[Q] Stuck In Recovery Mode - Optimus One, P500, V General

Hi Guys,
I am getting kind of desperate. I keep rebooting into recovery mode. Then, the screen shows Fastboot mode started... udc_start (). I think it is stuck. I am using LG Optimus ONE (P500). I have tried battery pull a lot of times. Doesn't work. Any suggestions? If you suggest I reflash stock rom or something, tell me how please. Thanks.

If you choose to reflash stock ROM, here is what you need:
- tools: http://forum.xda-developers.com/showthread.php?t=875881
- ROMs: http://forum.xda-developers.com/showthread.php?t=944881 or the link suggested in the tools thread
You may wait a little bit longer before reflashing to see if anybody has a better solution to your problem. Good luck!

More Questions... Help please if you can... Thanks
Hi All,
Thanks to those who have responded so far. I kind of needed the phone fixed ASAP, so I sent it for repair. But anyway, I have a few questions:
1)Is it possible to reflash stock ROM or a new ROM even if the the computer or Android SDK can't detect your device? (This is with the correct driver installed. When my phone was in the fastboot mode screen, it couldn't be detected as an LG Device at all when plugged in.) If you can, how?
2)For those who have successfully gotten a new ROM onto their Optimus One, how did you do it? Is there anywhere where the procedure can be found? And is it relatively safe? (I know there is always a chance you might brick your phone unless you are some expert, but there are some procedures that are safer than others right?)
3)This last question isn't really relevant to this forum section, but I'll ask anyway. Which phone models (any brand, preferably 2.2 onwards) are good for rooting and installing custom ROMs? Like, are there any phones that most rooting/ROM installing software supports? (For instance, I have heard that HTC phones can usually be flashed with custom ROMs without bricking that easily 'cos they are supported by stuff like ROM Manager etc.) And one more thing: what are the easiest/safest ways found to root/flash a new ROM?
Thanks everyone.

Yes it is possible, you'll need to firstly boot into 'emergency mode', by pressing volume up + back + power when the phone is off. Then follow these steps to flash stock rom. You do not use Android SDK at all, all you need is for the phone to get into the emergency mode, it is what most people with bricked phones do to reflash.

Personally, it was relatively easy for me even though I'm a new user to android. I've had my phone for 2 weeks and bricked it 3 times within the first 72 hours. But there are methods to get it back as I explained in Q1 XD In order to flash a new ROM, there are 3 MAIN steps.
1. root your phone
2. install custom recovery
3. make backup and flash new ROM
if you need help on certain individual steps, just post it here and I'm sure someone will help you.

In terms of the easiest method to root, it is definitely to simply run an app that can automatically root the phone for you, such as z4root, or SuperOneClick are just 2 examples. So I'll say whichever phones these app support, will be the easiest to root. ROMs will depend on the users of those phones and their dedication to creating customisable ROM. You can find most of the phones and available ROMs on this forum anyway.

Is it possible to exit emergency mode? Do you do a battery pull or something? I am planning to test out booting into emergency mode when my phone comes back from repair. Will it harm my phone? (Does it do stuff like wiping system data or my installed apps?) Thanks in advance to anyone who will reply.

I think you can just hold power to turn your phone off in emergency mode, but if it doesn't work, you can always pull the battery out. You didn't mention what you did for this problem to start but unless you perform the same thing, you won't need to use emergency mode.

when you said install a new rom, did you install it through kdz? if you did, try installing an optimus s rom through recovery. heres how:
download a rom on your computer
plug your phone in to you computer (with it already booted in recovery)
toggle usbms on your phone
transfer the rom to your phone
flash the rom

[Q] 2.2.1 - complications on downgrade and root.

Phone: LG P500h - ANDROID v 2.2.1 buildnumber FRG83.
Country: Brazil
Anyway, what I know is that i have to downgrade it to 2.2 in order to be able to root. I've looked through a bunch of tutorials on a bunch of websites but there are a few questions i have about the process that isn't answered anywhere i've looked.
Apparently downgrading requires me to get a stock ROM from LG, there is a topic here for that but it does not have the right ROM for my country, i tried a couple codes but they all got me 404.
Can I just flash any standard ROM from, US maybe, will it work?
And if yes, how do I flash it? Apparently you can do that by booting into recovery mode, but to get there you need it to be rooted which I can't do.
I've read about KDZ and downloaded that but... it crashes a lot in my PC (whenever i try the Read Device) it gives me error and closes the program (windows program not responding dialog).
I'm afraid it might crash in the middle of it if i try flashing and that would brick my device.
Is there a simple way to flash a new ROM? Is that the first thing I have to do in order to get a custom ROM say Ubuntdroid? It says I need a new recovery... but for that I need to downgrade first? It's a lot to do... and I don't really get the order in which I should do it all in...
Can somebody post me a little "do this, then do that, then finally do that" so that I can understand it all finally?
Thanks in advance, and sorry for long post, was trying to be as informative as possible.
This shows what happens when I try reading the phone on KDZ... also a little part showing that I got my device to be recognized by windows...
also disabled the LGE modem on device manager, read that if I don't it'll get bricked.
Well it won't let me link the image so... just paste the name together.

1. Find a suitable v2.2 stock ROM for flashing (link)
2. Use KDZ to flash it (I am not aware of another tool capable of doing that). Try doing that on a PC running Windows XP (important - that's where you're stuck now and I guess you're using Windows 7).
3. Root your phone - search for "z4root" on Market, install it.
4. Install Custom recovery, which will replace your current (stock) recovery mode (link - you may need to create an account on another forum in order to download).
5. Using Custom recovery you can now install any custom ROM and create nandroid backups to restore your phone to a certain (working) state.
You will have to use KDZ again if you ever want to flash a stock ROM, also losing the custom recovery. But you will have no reason to do that, except if you need to take your phone to some warranty repairs.
Good luck!
NEW PROBLEM: About step 1... i finally found a way to get my country's rom, but... it's.. the same thats on my device right now, it says V10a_02 and thats the same on my phone (the kdz read phone tells me that) so... won't I just be flashing the same 2.2.1 again?
http://csmg.lgmobile.com:9002/swdata/WEBSW/LGP500H/ABRABK/V10A_02/V10A_02.kdz <---- the rom the topic tells me to get.
How do I know what version of android is in that rom? and if i can't, can you link me to a rom that does?
I found one from another country that the guy said is 2.2... but... will it work if i flash that one? does it HAVE to be for my country? also my model is p500h (the h) is it different from the p500 (different as in flashing p500 without h roms on it will kill it?)
As for flashing it...
I think maybe a computer with win xp will do the trick for kdz.
i've found this post today:
http://forum.xda-developers.com/showthread.php?t=944881
is it better to use that than kdz? theres no replies on topic saying "hey it worked" so i'm a little worried, but apart from a few errors it seems to work on my win 7....
i guess the reply would be "i only know kdz, do it with kdz" but i thought i might ask...
Indeed, I have not tried that method and therefore I can't recommend it. At least KDZ is successfully tested. If you are patient enough to wait for some replies either here or in that topic, you may find out if it works. I would recommend it only if you have no other choice, like if you're unable to try KDZ on an XP machine.
In the mean time, I remembered that a newer version of Custom recovery is available (v1.2) - here. But you still need to download a file and read the tutorial from that other forum I mentioned in the previous post.
what about the first part of the post? i think i might have added that after you replied i don't know... asking about the rom i found if it isn't the same i have on my phone. and asking if i can just add another country's one...

First backup your data, then download a factory ROM, it doesn't matter which version u download, what matters is the version. Make sure that it's 2.2 and not 2.2.1 or 2.2.2. Follow all the below steps without skippin any, no matter how simple or stupid they are.
Link for shipped ROM - http://forum.xda-developers.com/showthread.php?t=865479
Now download KDZ updater and uncompress it
http://www.4shared.com/file/UleS4dP3/KDZ_FW_UPD_EN.html
Install msxml.msi from the uncompressed directory
Charge your battery to almost full state (I'm not sure, but it can be reason if phone doesn't start)
Turn phone off somehow (remove battery etc.)
Install drivers properly
Get rid of all usb drivers like Nokia, microsoft visual ++ run time environments
Install the LG drivers by selecting the update manager from the lg site
Disable LGE Virtual Modem. In your Windows operating system, go to Control Panel > System > Hardware > Device Manager > Modems > Right click on LGE Virtual Modem and click Disable.
Press and keep pressed "Volume up"+"Return" and connect USB cable to phone
Yellow screen with text emergency mode should appeared
Shake the handset (I know, it sounds ... strange, but it helps for ones, so... why don't try it?) UPDATE: Read some quotes on bottom.
Run KDZ_FW_UPD.exe (Has administrator).
Select Type : 3GQCT (I have one report that CDMA mod works too)
Select PhoneMode : DIAG (in case of fail try EMERGENCY, and as last chance use CS_EMERGENCY)
I Recommend do not switch phone off. There was some people, which done it and after they was not be able to turn it on again. If flashing failed, just select some another mode and try it again, again, try shake/connect disconnect, again, again....
In KDZ file : Choose the ROM file you downloaded in the first step
Press Launch software update
Shake the handset (I know, it sounds ... strange, but it helps for ones, so... why don't try it?) UPDATE: Read some quotes on bottom.
Now Root it via Z4root - http://forum.xda-developers.com/showthread.php?t=833953
Then install custom recovery - http://forum.xda-developers.com/showthread.php?t=844483
Then download n flash any ROM of your choice, I wud sugget install Void or LOL.
Edit :- By the time I replied, many have already replied. Anyways you can check my reply too :-D
Mithun.
"it doesn't matter which version u download, what matters is the version."
does that mean it doesn't matter what country or operator the rom is for, as long as it is android version 2.2?
i have one from portugal (not my country) and that one is made for P500 mine is P500H... if that makes a difference i don't know, but i do know that rom is android 2.2. can i flash that one?
i also have one that i got from that topic following the instructions of putting my serial number, it linked me to a rom V10A_02... on KDZ when i try to read my device it says i have V10A_02 too. isn't that the same one i have now? with android 2.2.1? if it is it's very pointless to flash the same rom already in it.
any way to check?
because that is my last doubt ;p

As far as my knowledge goes, the LG P500h you have is the same phone as the P500, only branded for Telus. The hardware should be identical, therefore you may use any ROM designed for the P500 family.
The only thing you may miss if you install a ROM not customized for a Brasil (or South America) network operator is the internet acces point name, thus rendering your phone unable to acces the internet trough its data service connection, but only trough WiFi. Nevertheless, the phone's APN can be configured manually, all you need are the correct settings from your mobile operator and you're good to go.
Ok since you guys told me i can go ahead and flash any country ROM i just did and now my device burst into flames and then the flames consumed my apartment.
ok, not. it worked too well actually, i did the kdz procedure on my win 7 anyway, despite the errors when reading device info, and it took like, 1 minute, rebooted, took like 2 minutes on the android screen then it came back, with all my data still there... i thought it didn't do anything but... its now version 2.2
i tried z4root, worked ... got the superuser app and.... i'm happy ^^ thaaaanks!
anyway about the custom recovery thing..
i'm going to install the one in that post you gave me...
but i read something about the best one being clockwork something...
shouldn't i go ahead and install that one?
or can i do everything i need with this one you guys linked?

You can do anything you need with ThunderG. Now that version 1.2 supports backup and restore of ext4 partitons (a feature you don't need if you don't plan on installing a custom ROM... but you will, eventually ), it is complete.
Moreover, in ClockworkMod's first topic says: "This recovery will not allow you to flash every ZIP file". ThunderG does, if you choose to allow flashing of unsigned zip files. Sometimes this is useful.
Peeeeeerfect
Recovery installed, LOL ROM installed, all fast smooth and error-free.
no more screen touch lag, it's soooooo much faster now, overclocked, i have yet to test my emulators but i can only guess they're gonna be at least 150% better lol.
thank you all very much for taking the time to help me ^^
ONE LAST QUESTION: I PLAN ON BUYING A NEW SD CARD, JUST PLUG IT IN AND IT'LL FORMAT THEN CREATE THE NEEDED FILES THEN I INSTALL STUFF BACK ON IT, SIMPLE AS THAT?
Simple as that =D
Although there are some criteria with the sd card or you'll get unmounting problems.
Use a class 4 or higher card
format with fat32
I've never officially tried this method but its apparently supposed to help

"The Saga of the KU3700 User" Custom Recovery Working!!!

Chapter 1: The Foolishness of the User
Hi, I have the korean version of the optimus one(KU3700). It was on gingerbread(2.3.4) stock. I was trying to root it by downgrading it. I entered "adb reboot recovery" and I'm stuck. I tried to reflash it by going to emergency mode with the button combinations using the KDZ updater with this
"csmg. lgmobile. com:9002/swdata/WEBSW/LGKU3700/AKTFBK/KU370040_00/KU370040_00.kdz"
and it worked without any errors but when it when it came up it was still on recovery mode. Is there any way I can change the phone mode to the regular mode
Chapter 2: Journey to Salvation
For anyone who has this korean optimus one, after days of searching, I've found a web site that gave me hints to solve the problem. I just needed a different kdz file and I got it here:
h t t p://sirospace.tistory.com/category/Android%E2%97%86
popped it in google translate because I'm Filipino and can't read korean.
Downloaded the froyo kdz and flashed. I hope this can help other people stupid enough to play with their phones by typing random commands without knowing what it does, like me, LOL...so happy, now it's time to root
Chapter 3: False Hope
OK so I have successfully unbricked and rooted my KU3700, now The problem I have is installing a custom recovery on this phone, none of the images I try work.
Recovery images I have tried are as follows:
recovery-RA-GNM-thunderg-1.1.0.img
recovery-RA-GNM-thunderg-2.2.1.img
recovery-RA-GNM-thunderg-3.0.6.img
Every time it finishes and reboots, it gets stuck at the LG logo.
Chapter 4: Wisdom Within
Found the problem. The images above are for the P500.Even if the KU3700 hardware is similar to the P500, flashing firmwares made for the other model will result in errors. The same holds true for custom recoveries.
Chapter 5: The Plea to the Gods
I've contacted drellisdee and submitted the files needed for custom recovery creation for the KU3700.
Just waiting for the flash image now. Thank you everyone
Chapter 6: The Forgotten
It seems drellisdee is busy right now. I'm a windows user and knows nothing about programing. So if anybody can help I'm sure the KU3700 community would be greatful. I've attached the files I think are needed to make a custom recovery.
Chapter 7: Quest for the Custom Recovery
I got tired of waiting. So as a windows user with no experience in programming, I did a lot of copying and pasting, I managed to port clockwork mod using virtualbox following this website:
h t t p://www.koushikdutta.com/2010/10/porting-clockwork-recovery-to-new.html
So I have got a bootable and flashable custom recovery but nothing works yet. I still need to configure it according to the device.
I have uploaded the image and the build files. Please help me configure it and tell me what's wrong. I really don't know that I'm doing
PS: you can try flashing the custom recovery by doing "fastboot flash recovery /Path to/recovery.img and you can go to recovery by using android terminal and type "boot recovery". It will boot, but that's that LOL. Take out the battery to boot to normal mode.
Chapter 8: The Holy Grail
LOL, I found the answer again. I was so frustrated that I kept squishing the phone in recovery and found out that it was just a button configuration problem. A bit of research and I found out that I can toggle it by pressing volume up and volume down at the same time. WOOHOO!!! Custom Recovery at last
Chapter 9: Invasion of the ROMS
And here at last, the user is retired. But the adventure is far from over. It is foretold that the creation of the Custom Recovery will begin a new era. The key to open the gate has been found. So our hero will await the invasion of the ROMS<background music...> END

Thank you for the reply but as I said, I can flash fine without errors it's getting back to regular mode I have a problem with. Rebooting and reflashing does not take me out of the recovery screen(it's just a opened box with an orange arrow and the android logo).

This is just a shot in the dark because i didn't understand what you did entirely : have you used the combination to actually recover the stock rom after you flashed with KDZ ? (Home+VolDown+Power)
Yes already did. The computer can see the phone whenever I connect it except that I can't access adb. I may have to take this back to the store

Are you sure you flashed the right rom for your phone? There's an application that downloads the required rom for your phone according to your IMEI/SN, but i don't know if it works with the korean version.
Yes it's the KDZ file, unfortunately it's the only KDZ file out there for ku3700. Shouldn't have settled for this korean version
why you wanna downgrade the latest version?
Dude I have the same Korean edition as you.
Actually why you wanna downgrade the latest version.?
My phone had 2.2.2 and I did upgrade it into 2.3.4 I did it officially and I can tell you How to re-install 2.3.4 if you want.

Thanks for the reply. I wanted to downgrade it to root it. And now I'm rooted. My only problem now is installing a custom recovery. I've already tried several custom recoveries:
recovery-RA-GNM-thunderg-1.1.0.img
recovery-RA-GNM-thunderg-2.2.1.img
recovery-RA-GNM-thunderg-3.0.6.img
but I get stuck at the LG logo when it reboots. I think it's because it's for the p500. So if you have a custom recovery for the ku3700 please help
I dont get it ,p504,p505,p506 are versions of p500??? And why some of our roms work on those phones?? So by logic this stock work on p500???

this method worked for my working KU3700 when I'm using my 1st KU3700 I also was struck as you and finely I realized there are No custom roms for Optimus one Korean edition (KU3700/SU370) and I had to connect my phone to an Octopus box (lg softwere box) via software box installed the official firmware. if this method not working you have to connect to a software box.
connect to the internet your PC and 1st install Driver and 2nd install the LG update tool. after installation connect your phone to computer and wait a five seconds for comport installation. after install your phone Run LG Update application.
it is connect to the server automatically indicating red line and after search for latest firmware.
if you can Update your phone it is shows Update butten.

Thank you all for the quick answers, but I already have a rooted ku3700. All I need now is a working custom recovery. If someone has the same phone, please tell me which image is compatible
you can appear the emergency mood with android logo.
it means you have an Empty phone. your Os was been erased. You have to connect your phone to Octopus software box and box server has you original Os for your IMEI. this is the only solution. if you will able to solve this problem without a Software box please inform me. we can open a New Thread for Korean edition.
(ku3700/su370)
I already got out of the emergency mode without an octobus box. It's really simple, you just need to use a different kdz file. The hard part was looking for the kdz file. I have 3 kdz files. KU370017(froyo), KU370033(gingerbread-rootable), KU370040(latest one from LG, gingerbread-unable to root). Just flash with the KDZ updater. I'm on the second firmware because I can't root the latest firmware. To root it, I used super one click(latest version, use zerg rush option). Now I'm just waiting for a custom recovery from drellisdee so I can use custom roms. When I get it, I'll ask him if I can post it so we all can have uber phones LOL

If you have flashed a working clockworkmod you can enter into clockworkmod via ROMManager (search in google play aka market). In ROMManager you have "reboot to recovery" option in case you want to go to recovery to flash something. Also you can try to flash from ROMManager a custom recovery (5.0.2.0 for oldBB or 5.0.2.7 for newBB), try to choose to phone model LGP500 oldBB, try and test if it's working. Wish you luck.
Thanks but I already have a working recovery. I just need some ROM makers now

Have you tried CM7.2? if your phone is very similar with Optimus One i doubt it isn't compatible with your phone.
If your phone use 2.6.35.10 or 2.6.35.14 kernel you can give a shot to try CM7.2 on your phone, but before try this make a backup first.
Check this thread Post Your CyanogenMod 7.2.0-RC1 Nightly Questions HERE!! for CM7 custom rom.
yep, it doesn't work. Is there a tutorial for building cyanogen for unsupported devices? All I can find are tutorials for supported devices. I've already got the source code from LG. The problem is just incorporating it in the cyanogen mod. I wish this phone had more users LOL

[SOLVED] [Q] Bricked LG L9 P769, locked BL, JB, Rooted, LG Bootloop

Hey all,
I have a CWM backup of my current rom and have backups of apps and data but am stuck at a bootloop.
As I have read countless articles, it seems my error is because I have a locked bootloader(not actually sure). Though, I only tried to flash
clockcycle's wiped v20d cwm backup file. It failed part way saying it couldn't write to /system.
Since then, I haven't been able to fully enter CWM. just see the red triangle with the droid guy on his back.
I have read Cmahendra's unbricking guide but it doesn't work as I have installed JB and even the tips to unplug, wait 10s and reopen the program to flash again it still won't work. Still stops at 15% saying error connecting to the phone.
There is a similar thread which had this exact problem which said to
use the online method to recover your phone since I had already installed JB. I edited the hosts file to remove the fake offline server and opened up the b2CAppsetup.exe, clicked on customer support,
entered my model LGP769BK and my S/N and it began to start the process and 'analyze' then crashed and said "updating is not possible any longer due to a fatal error while the LG mobile phone software Update"
I've tried to search this out myself and not waste any space but I'm at loss here. If anyone has any help, it would be much appreciated
as I don't have a phone while this is not working.
I've tried all the ways to to hard reset, master reset and still I get the droid guy on his back. I can get to S/w mode like all the other posts say to do but none of those fixes seem to work for me. Am I missing something?
Do I have any options here? I have kind of read that I should just unlock the bootloader but I don't think that applies in my case as I can't turn on my phone fully.
edit: for the online method(LG support tool), it basically cancels when it goes to the 'downloading' phase --> this is what I've seen as most of the answers but doesn't work
Upon further reading,
many seemed to need to replace their u-boot and x-loader
I did so and installed fastboot using Lelus' script here:
http://forum.xda-developers.com/showpost.php?p=41768774&postcount=1
I used option 6 which allowed me to flash the u-boot and x-loader from p760(works with my 769 and others as it says in the options) for JB
I'm not sure if I needed this as I don't have an unlocked bootloader.
I'm not sure of commands in fastboot but I ran
fastboot devices and it showed something
I also ran: fastboot flash recovery recovery.img
and I put one of my cwm backups in the "yours" folder
After I activate fastboot, it brings me to the C:\fastboot\yours folder
I assume this is for me to put my intended files in but I'm unsure if I should use my cwm backup or something else?
After it flashed the recovery img, I sent a fastboot reboot command
but it still went back to the droid lying down with a red triangle.
As some of you may see, I'm not too great with this but I feel like I'm close. Does anybody have an idea of what I should be doing?
should I flash an update.zip?
I don't know many commands but hopefully this gets me going in the right direction.
PLEASE HELP ME!!!!
I guess your cmw restore formatted your system but couldnt load the new system
the recovery you run with a locked bootloader uses a technique called 2nd init which i think is somewhere stored in the system partition. so when the recovery formatted the system, it lost itself too.
I've had a similar problem. the way out would be booting into the SW upgrade mode--switch off the device, remove the battery, remove the usb cable. press the volume up button and connect the phone to the computer. wait for a couple of seconds and then insert the battery.
you should be in the SW upgrade mode
now use the B2C client. if it gives an option to upgrade, use that otherwise, go to the customer support menu and press recovery phone
I have already done earlier. It may have gotten lost in my frenzy of information. I have put the phone into software mode, as you said, and it won't work either; There's no option to click upgrade because it's JB(V20D) and when I click recovery phone and enter my imei, LG mobile support tool(B2capp.exe) analyzes and then has a 'fatal error'
Since I flashed the new u-boot and x-loader my screens are all backwards/mirrored. Maybe the tool flashed an unlocked u-boot and x-loader if that's possible.
Is a recovery possible by fastboot?
I have a clean and full copy of my cwm recovery as well as apps and data backed up, I just need to get this phone in working order

If you fastboot flash the u-boot and x-loader from p769(ICS) it should go thru with the offline flash detailed in cmahendras guide.
http://forum.xda-developers.com/showthread.php?t=2085344
Use the KDZ_FW_UPD.zip from this thread
Or try this
Remove all of the stuff you have downloaded for this. Download the original B2C client from LG's site and use that

I have the updated kdz fw upd .zip from the unbrick and root thread as well as downloaded a new, official B2C client but they all still hang at the download part during phone recovery.
Tablechair, that did the trick.
Is this because the tool we use to flash for the offline method doesn't recognize the x and u-boot loaderse of JB?
After I installed the ICS boot loaders, my software upgrade mode wasn't mirrored anymore.
I did as tablechair and flashed the V20D.
Does anyone understand why this problem happened in the firstplace? Maybe I didn't get a full copy of clockcycle's backup cwm
or should I have not flashed his recovery in the first place since I didn't have an unlocked bootloader?
Again thank you for all your help and if anyone can provide answers to my other supplemental questions, that'd be great.
Off to root and probably unlock bootloader to be sure.
edit: I can't find the thanks button. but thank you very much tablechair. much appreciated. Hope this can help someone else
p.s. also big thanks to those who made the fastboot program for p769(Artas182x and sguerrini97). really an invaluable tool as I now know.

Things don't always go according to plan, maybe his Clockworkmod backup was made from the touch version and he didn't have artas182x second init recovery installed. So when the cwm failed the first time, did you try to restore your cwm backup?

Not yet. having problems flashing a kdz again. I've tried the 2 different software modes, as well as setting emerg and diag but still getting stuck at 15% again.
Do i have to replace my uboot and xloader with the ICS ones every time I want to use the offline flash method?
edit: yup, after replacing with ICS loaders again i'm able to flash using software upgrade. will update on whether I can restore cwm

I realized I misread your question. When I flashed before the incident, it failed to write to system and I didn't restore my other folder. I rebooted and it was all missed up. Anyway, now that I've got everything back and now with an unlocked bootloader, i was able to recover my old image. However, data isn't working so I have to find the radio to flash as I recall reading in other threads.
Can someone explain in laymen terms why this is? recap, i was on unlocked bl rooted jb and I flashed my old cwm backup when I was rooted but had a locked bl. My apps and messages were all there but the radio was different. I'd understand if I was going from ICS to JB but I was on JB both times. The only difference being a locked BL. It's got to be something about the Radio from p760 or V20B that didn't work on my earlier backup or something like that because the layout status bar is different with a "data" button and showing H instead of 4g(which are the same afaik).
Since, I restored to my backup from after my bootloader unlock and root so data is working showing 'H' with the different layout
Also, I had problems backing up and restoring until I noticed that it works better when I power off the phone and do the manual commands to enter recovery as opposed to using the app to send me to recovery(where I incurred /system backup errors).
My last question is which cwm recovery should I use? I currently have the one for a locked bootloader installed as per Artas182x's website. On that post he has a link for an unlocked bootloader recovery on the xda forums but that thread was updated to not working. Are there any disadvantages to me using a locked bootloader cwm recovery?
I don't think I have any option but to try it as I want to flash CM10.1 for p769. I also read that if your bootloader is unlocked, you can download the cwm from the googleplay. If this is true, can I just install over or should I uninstall the Artas182x locked bootloader one????
update: have to remove l9 recovery by deleting the appropriate system folders and then flash the appropriate .img through adb commands
Help.

Although I might be late, I have the same problem and the same phone and I really need help. I have a soft bricked phone lg optimus l9 and I had the same problems that you had exactly... Which is weird exept I don't have Clock Work Mod or anything ... If you get this I would really appreciate some help. Thanks
yup me too
I finally got software upgrade to work with my lg p769 that was security error cuz i still haven't unlocked the bootloader, if i knew what a good job lg and T-Mobile did in locking it i would have waited and got a g3 that my buddy rooted in like 5 min and unlocked the boot....
What worked for me is this LG FLASH TOOL 2014 THREAD ON XDA
http://forum.xda-developers.com/showthread.php?t=2797190
flashed both the 20H and 20D successfully i uninstalled everything lg in the control panel first though.
Hope this works for you cuz i was struggling on and off for a month to get this far lol
the 2014 tool ultimately worked for me too, once I fixed a couple things. I had rooted and forgotten to unlock, so it was at Security Error, and it would also disconnect at 15% .. in the 2014 tool, I had to install all the updates even though I'm in windows 7 or it would keep doing it. All good now.
I have been trying all these methods and I am still not able to get in the S/W upgrade mode. The only thing I am getting from the device is being able to put it fastboot mode (The inverted one). I really want to revive this phone
Thanks in advance for any help given

Hey, it's been ages since I have done any of this but IIRC, if you can get into fastbood mode u can still get into software mode,
- turn phone into fastboot mode
- open the software upgrader thing as you normally do
- maybe switch emerg to diag or something like that
- this part is where it's slightly different than the normal way(same program but u select a different option than the default 1st option on
I think if yoiu look through the tutorials it does mention an alternative method for getting into software mode
in one instance in my past, i had to reflash the ICS boot drivers so the software installer would recognize that
the flashing of the ICS boot drivers is done through fastboot. Should be a post in my history where I asked a question regarding this.
Sorry for the chaos but maybe this will help you get in the right direction since I don't know any of your phone history and what you've done etc
best of luck mate

Hey, I have been trying it with the fastboot but it keeps timing out and not allowing me to finish. One thing I should let you know is that, ever since I had put the device in fastboot, I am not able to get back the S/W upgrade mode. Dont know if that will help in seeing what my problem is or if you want me to explain everything from the beginning again, I am more than happy to.
Have you followed the steps that I linked to in the first 3 posts of this thread?
Follow the steps to flash the ICS bootloaders in fastboot and then you can do the fastboot trick for getting the software to recognize your device.
Right now your phone has the JB boot loader on it and is thus not recognized by the software.
recap:
step 1: flash the ICS bootloaders in fastboot (look at the linked thread in post 2)
step 2: use the software in emerg or diag mode but sitll follow the same steps as the tutorial. I think my earlier posts should explain precisely.
if you dont flash the ICS bootloaders, it won't be recognized by the KDZ installer

lg l9 p769 - droid 4.0.4 - i'm lost, could use help, linux user

i have been seeing a lot of threads about rooting this phone, but, they all have windows scripts, even the thread that is said to have a runme.sh does not have it in any of the links that i unzipped - only a runme.bat, but yet, people keep mentioning a runme.sh in it... also, i really don't see any one lying out the steps for doing this with linux.
i'm a noob, and dont really know much about this stuff, but i've done this ONCE before with a galxy exhibit, but it was very easy, i just copied a file to the phone (stock rom?), rebooted into recovery, told it to recover from that file, and i was done.
i have no idea how to do it with my new phone, and so i'm wondering:
1: where can i find the files i need to do this with linux - i just want root, nothing special
2: where can i find the steps necessary to do it - in the easiest manner possible?
3: it says i have droid 4.0.4, ICS, but every one who talks about lg l9 p769 says its JB, so, thats a bit odd...
any help is appreciated.

Your phone is running ICS 4.0, that is the version which it shipped with. Pretty much everyone on here has upgraded to JB either with software update on the phone or they have manually updated with the offline KDZ flash method.
I dont have any experience in linux so I cant help. I hope you can get your phone rooted!

but even if it does upgrade to JB, i still wouldn't know how to do it on linux. i figured there would just be some files to download, and a sequence of adb commands that i could type into bash, but, i'm kinda lost. i guess i'll wait and see if it upgrades to JB before asking more questions.

Option #1
If you are rooted on stock T-Mobile 10e or 10g ROM and have the CWM installed from this thread:http://forum.xda-developers.com/showthread.php?t=2095825 follow my instructions.
Place one of these CWM ROM images on your SD-Card:
http://forum.xda-developers.com/showthread.php?t=2136204
Place this JB radio firmware from T-Mobile 20d ROM on your SD-Card:
http://forum.xda-developers.com/showthread.php?t=2256350
Power off the device.
After power on the back/menu capacitive buttons will flash repetedly. Press Volume down while the lights are flashing and the phone should go into recovery.
Flash the ROM first.
Flash the radio second.
Reboot.
***Notes***
1.) 20d is the latest T-Mobile, 21b is the latest Wind Mobile. Both work.
2.) 21b is lighter/faster but has no wifi-calling.
3.) 21b will require you to manually enter your APN settings for cellular data and MMS. Be sure to write down your APN settings before flashing this ROM.
4.) Some users say battery life sucks on JB. I notice that 21b is better on battery life than 20d.
Option #2.
In Linux install a Windows VM and follow the standard instructions here:
http://forum.xda-developers.com/showthread.php?t=2173465
Use KVM with a GUI or even easier use VirtualBox.
I'm a die hard linux geek too. I even run linux at work while all of our msp software was written for windows. You are better off just running an old copy of xp inside virtualbox trust me its just easier that way. You can use adb if you like (its the same thing the windows users use in their batch files and just rewrite the bash script, but you will save yourself lots of headaches just using virtualbox. -- my .02

i'm not exactly sure what the end result of your instructions are, as i assumed it was to BE rooted, but the first line of your post says "if you are rooted ...", so, i'm guessing you're telling us how to ... unlock the boot loader?
by the way, that reminds me, i still haven't come across any posts on this site that tell noobs:
# what's the unlocked boot loader FOR - why do you need this - what does it do?
# what's the difference between unlocked boot loaders and being rooted?
# do you have to unlock the bootloader to get root access?
all some one like ME needs, is root access, so that i can edit the /etc/hosts file and test mobile compatibility of web apps on the development server before making them live - and to remove t-mobile damned bloat-ware. i hope this helps others who are trying to understand the basic concepts of getting control over the phone they paid money for.
thanks again. now to find a winxp image to load into a virtual machine...
My bad. I should have read through your original question all the way before posting. I see that you are not rooted.

It will require rewriting the batch script as a Linux shell script. It is possible but nobody has done it yet.
If you are on 10g you will need Windows. I have also answered your questions below.

i'm not exactly sure what the end result of your instructions are, as i assumed it was to BE rooted, but the first line of your post says "if you are rooted ...", so, i'm guessing you're telling us how to ... unlock the boot loader?
by the way, that reminds me, i still haven't come across any posts on this site that tell noobs:
# what's the unlocked boot loader FOR - why do you need this - what does it do?
It allows you to boot an un-signed kernel. You can boot custom ROMs basically.
# what's the difference between unlocked boot loaders and being rooted?
Root allows you to `su -` to the root user and own the whole system.
# do you have to unlock the bootloader to get root access?
No.
all some one like ME needs, is root access, so that i can edit the /etc/hosts file and test mobile compatibility of web apps on the development server before making them live - and to remove t-mobile damned bloat-ware. i hope this helps others who are trying to understand the basic concepts of getting control over the phone they paid money for.
thanks again. now to find a winxp image to load into a virtual machine...

yeah, the one t-mobile is selling now is a v10g - so, it's time to play with virtual machine, and hope that usb-access is passed through from ubuntu to the VM.
thanks for answering the other questions. i think this essentially sets things straight.
peace! \m/ (>_<) \m/

Welcome!
I know that a long time ago when I ran VirtualBox in Ubuntu there was something I had to do to allow USB access to the VM.
Here are the current instructions directly from Ubuntu:
https://help.ubuntu.com/community/VirtualBox/USB
Good luck.
hey, i've got 1 more quick question: is there a way to simply load a pre-rooted ROM onto it, like i did with my samsung? where you put it onto the device, the go into recovery mode and choose the pre-rooted ROM? i haven't seen any mention of that, so i'm not sure if that's an option...
also, how the hell do you make this boot into recovery mode? i still haven't been able to get it to do that?
thanks \m/ (>_<) \m/

Yes you can flash a pre-rooted image. They are available. Use the search?
I posted instructions on the first page showing how to boot recovery.
that's great news - that's all i really needed - i didn't see them before, at least, not conspicuously, but i'll search around again.
and, i must have some how missed your instructions, i'll look again.
thanks!

those steps assume i have CWM installed, and i don't. i looked at installing CWM, and it doesn't have an official recovery app for the p769, and when i went to look at that thread you linked to, it says you must be rooted already. this is the aggravating part of us ignorant people dealing with people who know many things: it appears to us that you have to do some thing that requires that it is already done before you can do it. it doesn't make any sense - just a bunch of circualar requirements, with no beginning.
so, let me ask this a different way: how do i reboot into recovery mode, on a STOCK LG P769 v10g? the lights do not flash, and i'm assuming that is a CWM feature - but CWM is not installed - this is COMPLETELY STOCK - fresh out of the box. so, what do you press, when turning it on, to make it go into recovery mode, so that you can recover from a pre-rooted rom (which i am still looking for)?
i just want to "recover" to a pre-rooted rom, that's it, so that i can delete bloatware and edit the /etc/hosts file (for web app testing). this thread says you cant do this for LG phones http://forum.xda-developers.com/showthread.php?t=2174767 - i got the same result the last guy got . trying to borrow a windows computer now...
also, does any one know if it is safe to put a jelly bean rom onto a device that was using ice cream sandwich? is there a difference between the versions that would brick the device? is it not recommended, or is it highly recommended?
thanks again. sorry for all the confusion.
you know, as a side note: it may help more noobs understand this stuff if there was a sort of simplified glossary, perhaps as an official site thread, for the orientation of noobs, that would give an outline of the basic concepts, AND their order of operation. exmaple: "rooting is when you... bootloader unlocking is when you... CWM is for people who want to... you MUST do A before you can do B and then you can optionally do C if so desired...". that would help them understand where to START, then, where to GO next.
well, borrowed a windows computer and i got it rooted, but, i found out a few things about this exact model: it has no "boot to recovery" option, by default - it's locked down pretty good. you can not use any of the other root methods on this model, and you can not do it from linux (f*ck me).
so, that long-winded fake-software-update-while-switched-out-a-hex-edited-binary-file is the ONLY way for this exact model, it seems...
but, at least i can confirm that this exact model CAN be rooted at all
now to remove alllllllll the bloatware... and look into this CWM more and learn more about what is actually IS and WHY so many people install/use/flash it...
hey, does any one know if cyenogenmod ever got themselve's an "app/marketplace"??? that was one of the draw-backs to installing it, last i checked.
thanks @everyone for your help.

I've decided to help you out This page will give you some more info on the P769 and several kdz (roms) for the P769
The fastest way to root is to flash the V21B kdz (this is the Jelly Bean version for Canada) using this guide, http://forum.xda-developers.com/showthread.php?p=36351786
The reason why you want this rom is because it has a vulnerability that is easy to exploit with Jcase apk
Once your followed everything (and rooted), install Super Su and Busybox
Next install artas182x second init CWM (in case you can't find it on his page, the link is here )
Note: you will see blinking led lights when you see the LG logo (booting up) appear after a couple of seconds. To enter the CWM press the vol (-) when the lights start flashing.
After you installed Artas182x CWM you can recover from someones clockworkmod backup.
following info from Cmahendra's thread
Note: only restore CWM backups from P769 versions or MS769!!!!
Or check out the V10B (MetroPCS "JellyBean") CWM backup
Now the only 2 reasons to unlock the bootloader are:
1. Install a safer and better CWM
The reason why is because Artas182x CWM is a second init (bootstrap), so if you mess around with a busybox apk and something goes wrong or you remove a file that is required (for CWM), it will stop operating. You will have to reflash the kdz or fix what you changed to get it working again.) I've had this problem several times while messing around with different busybox apps and etc.
2. Custom roms
(which you stated you are not looking for) not worth talking about right now.
Answer to questions
The only pre rooted roms are clockworkmod backups, lol
The default recovery is useless to us (unless you feel like solving the problem)
Flashing back and forth (ice to jelly) comes with risk, the program used on Windows to flash is buggy at times. The best way (in my opinion) is to flash only when really required and mostly restore from clockwormod backups. The device is actually hard to hard brick, but it will require at lot more knowledge to get your device running again.

So what version are you on right now
Ice? Jelly?
i'm still on ICS for the moment. still trying to understand what i need to do next. re-reading your post for the 2nd time, and all the threads it references. making sure i don't screw any thing up. thinking about upgrading to JB, and trying this CWM. and looking into this "cyanogenmod" some more, to understand why i never see any one on this site mention it, and what all these "other roms" are about. lmao, like i said, i'm way new to this . it's a lot to take in, even for a web developer .
thanks \m/ (>_<) \m/

Android Unusable

Hi, good evening to the community!
(EDIT: Anyway, I want to apologize if I'm doing something wrong. I recently joined).
I believe I made the biggest mess of my life, and now I'm desperate. I downloaded the latest version of TWRP, to update the one I already used; the problem is that. Now he is no longer in Recovery Mode. And worst of all? I had already deleted my OS. So, there's no way I can authorize OEM unlocking. So I can not use ADB & Fastboot. And I think I have to throw my device away as it is unusable. What should I do? I'm desperate and there are no solutions.
-Thanks

There is no need to worry if you corrupt you recover, just enter into bootloader mode then flash the recovery.
code:-fastboot flash recovery moto.img
Note:- Moto should be replaced with the recovery name
If you want to return to stock ROM then here is the procedure:-
Firmware:-https://mirrors.lolinet.com/firmware/moto/surnia/official/
Procedure:-https://www.google.com/amp/s/forum....tore-moto-e-2015-stock-firmware-t3044936/amp/
Done now you are now stock ROM .

Yes thanks! I did it yesterday, watching a Brazilian video. I had to download 3 different ROMs to be able to do such a process; so I did the process through Fastboot. Thank God I did not have to buy another device, hehe. And I'm already using another Custom Rom at the moment (RR, but I plan to change it as soon as I find another great new one that does not bug WhatsApp). Thank you again!
