So, I have CyanogenMod 7.0.3 Stable flashed in my Legend, and it's been working just fine. Until couple days ago when I made some theme changes through Theme Chooser and flashed some theme add-ons. Now the phone is acting just stupidly. It's in a bootloop (sometimes loops in HTC bootscreen, sometimes in the CyanogenMod bootscreen), usb connectivity doesn't work (fastboot usb works, adb/mass storage etc. doesn't). I have tried to wipe the phone and flash that rom/recovery again through fastboot, but fastboot says "remote: not allowed" or something like that. Bootloader works, fastboot works, even recovery works but it's no use 'cause adb driver doesn't recognize the phone.
Please guys, help me. What should I do to get my phone running again? (working CyanogenMod or even a stock without root, I don't care, I just want this thing up and running again)
EDIT: And the weird thing is, that couple times I was able to boot the phone normally using recovery by just sticking the usb cable into the phone. And also, couple times I was able to boot it normally by just using fastboot reboot (I was able to get to the HTC Setup screen and then it would crash and show just black screen with notification bar)
It's possible the you're USB bricked. A quick search of "USB unbrick" should bring the required thread to light (search in development)

Yeah, I have thought of that! Only problem is that how am I supposed to get the required files (flash_image and .img) to SD card without a way to manage SD card? Can I flash the image using fastboot?
I can't do it inside the phone 'cause I'm in a bootloop and can't boot the phone.
EDIT: Is there a chance to do a wipe and flash a new rom using only fastboot or something?
In theory you can flash without recovery, but only if you're S-OFF. You'll need the ROM in .img format too.
I used a microSD to SDCard reader to transfer the files., they're fairly cheap in high street stores. Or borrow a friends Android phone

Well, am I able to flash those files once they are in the SD card? I mean with S-ON cause I don't have S-OFF?
Or is my phone a complete brick? =( Cause I'm pretty much all out of ideas..
Once you've got the files needed for a USB unbrick on your SD card you'll be fine
if you have recovery access did you try to make apply update from SD card in order to pass in cwm recovery.
if you got a USB brick you can use a multifonction printer to mount your SD on your computer.
So in a nutshell, my problems are:
- My Legend is in a bootloop
- Apparently my phone is USB bricked cause only fastboot works
- I don't have a recovery, when I go manually into recovery (recovery -> POWER + VOL UP) it goes into stock recovery
- And also my phone is S-ON
Could you guys point me into the right direction with this, I really want my phone back working. What should I do?
When you get to the stock recovery, navigate to ans select "flash update.zip from SDcard" That should get you to ClockworkMOD. Once there you'll need to use ADB to push the files required for the USB unbrick procedure to the SDcard (adb push [files-on-pc] /sdcard/) You should no be able to perform the the USB unbrick.
You may need your phone plugged into a PC for it to boot

But I'm getting this blue recovery screen with only four options instead of the original green one including option to flash zip. So wtf has happened?
EDIT: In the blue recovery screen it says Can't open cache/recovery/command. And when I choose "apply sdcard:update.zip" it says "signature verification failed" and it aborts the installation.
Fakeflash.

So I am able to flash roms only using this menu? Am I correct? Just do a wipe and apply update.zip?
Why does it say "verification failed" then?
EDIT: Oh I see, I have to download fake-flash update.zip and apply update.zip takes me to the clockwork recovery? When I put the update.zip to the SD card and apply it, then it should go on with out any "verification failed" errors?

My main priority is just to get the phone to run normally again, I can worry about the USB Unbrick later. So I just want to do a full wipe and flash Cyanogenmod again. Am I able to do all that is required to run the phone again normally with fakeflash?
Thanks in advance TheGrammarFreak, I really appreciate your help!
The phone won't run normally until you do a USB unbrick.
One of the things that happens with this USB brick is that a flag for advanced debugging gets set. It's a very deep setting, and the setting is read ad the HBOOT level. If this flag is set to on (like it is in a USB brick) the phone will not boot unless it's plugged into a computer. Remember that
In order to get your phone back I believe you will need to plug your phone into the PC and turn it on. It should boot, if not you will need to get to recovery and wipe/reflash (you'll need to do this while plugged into a PC too). Once you have a running system/you're in recovery you can use ADB to push the files needed for a USB unbrick to your SD card.
Assuming you got that far, you should be in a prime position to follow the USB unbrick procedure.
I'm going away tomorrow for a week, and I will not be online at all. If you need more help you will need to get someone else in. That said, I believe that with the information in this thread, the USB unbrick thread, the fakeflash thread and Google you have enough information and help top fix your phone

Legend is up and running again! Thank you so much TheGrammarFreak!
Same problem here, but slightly different. He doesn't recognize my SD card (tried different ones) anymore ... out of the blue ... so how can I unbrick ??
http://forum.xda-developers.com/showthread.php?t=751265
follow this guide, helped me a lot.
you'll need root access.
Hello...I use a Samsung S Advance GT-I9070
Recently I tried to root it by copying root.zip , update.zip and TWRP file into the external SD card by connecting it to my PC.
Then I tried to install root.zip file using stock recovery I was facing this error "E: signature verification failed" every time I did it.
Then I tried to flash CWM via odin3 by putting my phone on download mode and connecting it to PC but after pressing stat in odin3..I got an error that the process failed. I tried 2 more times and still the process failed.
Then I thought of rebooting my phone but I was getting this message "firmware upgrade encountered an issue. please select recovery mode in kies and try again" so I tried kies to recover it but it wasn't working.
So then I put the phone again in download mode connected it to PC and then used odin3 to flash TWRP and the process was successful and the phone got recovered.
But the MAIN PROBLEM is that when I tried to put phone into TWRP recovery mode and install the root.zip file it's not showing me the contents of SD card. I tried to weep the phone do the factory reset and then try and it is still not working.
PLEASE HELP ME WITH THIS PROBLEM....I'll be very thankful to you!
PS: Basically I want to root my phone and install cyanogenmod 11 to get android 4.4 kitkat in my phone.
Hello, I'm a little bit new to all this, so any help and detailed instructions are very very helpfull.
So I have Gigabyte GSmart Aku A1 device (MediaTek 6589), I don't know if it's bricked or what but apparently is not working quite well.
When I turn on my phone, it just loads and loads and loads and nothing happens (waited for about 4-5 hours), that was starting to happen after I somehow installed CWM on my device with some tutorial, CWM worked for the first time and after next reboot, it disappeared and stock recovery came back (and the problem with infinite loading screen - only showing logo).
I have ADB drivers installed, SDK aswell, tried to put stock firmware (got it from official site) and in like 1/4 of installation it says:
Code:
symlink: some symlinks failed
After that, I tried to install few versions that I downloaded from that official site, but same error again and again. (I tried to install with SD card and with ADB too. ADB is only working when I go to "apply update from ADB" in recovery. I have also used 2 different types of SD cards.)
That didn't worked either, so I got to some russian forum, and using google translator I downloaded 5-6 types of custom ROM's / Firmwares. That didn't worked either, one time when installing one of those ROM's - it said something about signature..
After that I was trying to install those ROM's with ADB and with SD Cards aswell, but turns out that every single time I get error saying: "Installation aborted.".
I have ofcourse tried to wipe data/factory and to wipe cache too, but nothing helps..
Also, when I'm in ADB console, when I type any command besides adb sideload or adb devices, I get error saying: "error: closed". I cant get into fastboot with adb console.
I really don't know what to do anymore, so any help would be very very appreciated. Thank you for your help in advance, if you need any videos, pictures or something, just tell me.
Edit: When I go to "wipe data/factory reset" in recovery, it says: "Mount /data error.".

i would look for stock rom in form of full mtkdroidtools backup and preloader drivers for your mtk chipset
and flash it using flashtool (it uses preloader[you can determine if it's available/undamaged by turning phone off and opening device manager on pc and plugging phone to pc if there will be a flash in device manager before the charging starts it will flash ])
This is now DEPRECATED and NOT SUPPORTED ANYMORE since there is an easier method to do it! Links won't get updated! You can still use the written info!
If you want rooted kitkat head to my friend's thread @maxx_hr (THANK YOU FOR ALL YOUR WORK!) HERE: http://forum.xda-developers.com/optimus-l3-l5-l7-l9-ii/development/kk-kk-kdz-p710-root-t2950532
Hello to you all!Warning:
Code:
[COLOR="Red"][SIZE="4"]Your warranty is now void. I am not responsible for bricked devices, dead SD cards,
thermonuclear war, or you getting fired because the alarm app failed.
Please do some research if you have any concerns about all contained in this tutorial
before you follow it! YOU are choosing to make these modifications, and if
you point the finger at me for messing up your device, I will laugh at you.
But since i'm a nice dude i will try to guide you anyway:)[/SIZE][/COLOR]
In this tutorial we will learn how to:
- achieve root on our L7 II (Both single and dual-sim, so P715/P710 and all the derivated phones from them) by LG running a Custom Rom or Stock KK Rom.
FOR THIS FOLLOW ALL STEPS.
- unbrick/flash to a specific firmware using Lg Flash Tool (In this tutorial there are only 2 KDZ files stock JB for P710 and P715. If you want to recover from a brick or want a different KDZ file you can find them over here: http://lg-phone-firmware.com/)
FOR THIS FOLLOW STEP 1 AND STEP 2 (install all drivers including adb and download the files that are needed at Step 2).
- flash with CWM (There are 3 methods I describe. Use the one that suits you the best. You can flash any *.zip that is suitable for your device.)
FOR THIS FOLLOW STEP 5.
Save your data you need, you will lose all data so backup with Titanium Backup or a program you like the info you need.
ALL DOWNLOADS ARE AT THE BOTTOM OF THE POST!
This tutorial will be split in steps as the following:
1. Preparing the Windows machine with the right drivers and software.
2. Reverting back to Jellybean Stock Rom.
3. Rooting on Stock Rom (Jellybean).
4. Installing Unlocked Bootloader and ClockWorkMod Recovery (CWM).
5. Flashing KitKat or a Custom Rom through CWM.
6. Flashing Root through CWM.
So let's start the job.
1. Preparing the Windows machine with the right drivers and software.
Uninstall everything related to LG from Control Panel (Drivers, PC Sync etc).
Restart your PC.
Download and unrar the archive "LG Drivers.rar".
Install both files inside and restart your computer.
Download "adb-setup-1.4.2.exe" and install it (answers should be y y y and install the drivers when prompted).
Download "Framaroot-1.9.1.apk".
Download "LG Flash Tool 2014.rar".
Download "Free LG P710.rar"
Download "P710 Stock KK.zip". -> Stock KK image with Stock KK kernel in it made from the original V20 KDZ (Open Europe).
Download SuperSU
*Download "P715 Stock KK.zip" and "LG P715 (JellyBean).kdz" if you are running a dual-sim version of the phone.
*Download all the files you need!
From now on I will consider you have this files and I will just call their names when to use them.
2. Reverting back to Jellybean Stock Rom.
Open the back cover of your phone and pull the battery out. Wait about 10 seconds. Put the battery back in.
While HOLDING (keep pressed) the VOLUME DOWN BUTTON insert the USB Cable in the phone (you need to have your USB cable inserted in an USB 2 port from the back of your PC).
When you see the yellow screen with emergency mode stop pressing the button.
Unplug the USB from the phone and then plug it in again.
Unrar "LG Flash Tool 2014.rar" and open "LGFlashTool2014.exe" with right-click Run As Admin.
*If you cannot open this program you need to install "VC_RedistInstaller.exe". You are missing some libraries of visual C++*
*IF YOU HAVE ANOTHER PHONE (another LG or P715) DO THE SAME INSTRUCTION AND REPLACE JUST THE KDZ FILE ON "Select KDZ File" TO THE ONE YOU DOWNLOADED AND IS SUITABLE FOR YOUR OWN DEVICE.
Move PhoneMode from DIAG to EMERGENCY. Select KDZ File: you have a file called "V10J_00.kdz" in the same folder as the tool. Select that. Press CSE Flash (CAUTION!!! This will reflash the phone and YOU WILL LOSE ALL YOUR DATA SO BE WARNED).
Another screen will open and press START.
Another screen will open once again press OK.
At a point you will get an error like "Offline BLA BLA". DON'T DO ANYTHING DO NOT PRESS OK.
Wait until your phone reboots and then you can close this tool.
Remove USB cable.
IMPORTANT STEP:
Pull out the battery. Wait 10 seconds put it back. While holding VOLUME DOWN + HOME BUTTON press POWER BUTTON. Wait until you see LG logo and stop pressing POWER. Keep pressing the other 2 until you see android robot doing things. Wait until the phone boots.
CONGRATZ you are on JELLYBEAN (Or the KDZ you chose).
3. Rooting on Stock Rom (Jellybean).
When you see the welcome screen just fast forward everything.
Go to system settings->security->tick Unknown sources->OK.
Go to system settings->developer options->OK->tick USB debugging->YES.
With an SD card reader or with your USB connected as Media Sync (MTP) copy the "Framaroot-1.9.1.apk" to your SD Card.
Using the phone's FILE MANAGER go to external_SD and click the Framaroot you just copied. Run it using Package Installer Just Once and Install.
When finished press OPEN. At the first choice choose Install SuperSU and then press on "Gandalf". You will get Success. Press OK and reboot.
You will see SuperSU in you apps.
YAY! IT'S DONE.
4. Installing Unlocked Bootloader and ClockWorkMod Recovery (CWM).
*SAME FILE YOU NEED FOR LG P715
Earlier you have download "Free LG P710.rar" and in the first step you installed ADB. We will use that now.
Unrar the "Free LG P710.rar" and place the 2 files ON THE ROOT (only on root) of the SD card using device mounted in MTP mode or SD card reader. Put back the card if you use the second option.
WARNING!!!
This can mess up you device so just do what i say step by step!
Plug the USB Cable in the Phone once again and use MTP connection mode.
Click Start+R type CMD and press ENTER.
Run the Following with copy paste to CMD.
Code:
adb devices
You will see your device.
*IF YOU CANNOT MAKE YOUR DEVICE BE RECOGNIZED IN "adb devices" do this:
Install this: https://play.google.com/store/apps/details?id=jackpal.androidterm&hl=ro
Open terminal and continue with the steps down below.
Code:
adb shell
You will see something ending with $.
Code:
su
Unlock the dvice if it is locked and your phone will ask for superuser permission press GRANT.
Code:
dd if=/storage/external_SD/APPSSBL.bin of=/dev/block/mmcblk0p5
This will copy the unlocked bootloader to the bootloader partition.
Code:
dd if=/storage/external_SD/recovery.img of=/dev/block/mmcblk0p17
This will copy the CWM to recovery partition.
Code:
reboot recovery
This will reboot your phone in CWM if you followed all steps correctly.
GREAT SUCCES we have an unlocked bootloader and CWM.
Close your CMD.
Unplug USB.
5. Flashing KitKat or a Custom Rom through CWM.
*IF YOU WANT TO FLASH ANOTHER ZIP FILE OR YOU ARE ON P715 JUST USE THE ARCHIVE YOU NEED AS REFERENCE, NOT "P710 Stock KK.zip". CHOOSE THE FILE THAT IS MOST SUITABLE OR YOU THINK IT'S BEST FOR YOU
I made "P710 Stock KK.zip" you downloaded. This is the stock image for KK Open Europe. Here you can either flash mine or search for a Custom Rom for your device. Either way you will follow the exact same steps but with a different archive. I will take for reference the "P710 Stock KK.zip".
Plug USB in.
You Navigate using Volume Up Button (UP) and Volume Down Button (DOWN). The Power Button is OK.
Do this:
- Go to "wipe data/factory reset" and OK. Go to YES then OK. Wait until done.
- Go to "mounts and storage" and do the following: "format /cache" and "format /system" everytime with YES as second option. Press "go back" once.
- Go to "advance" and then "wipe dalvik cache" and YES. Press "go back".
Here you have 3 options.
OPTION 1.
Use an SD card reader copy the Zip file to the root of the SD card or copying using CWM. Using CWM you navigate with Volume Up and Volume Down to "mounts and storage" press POWER BUTTON (OK). Go to "mount USB storage" and your SD card will appear in windows and you can copy. After that you press "go back" 2 times to get to the main menu.
Go to "Install zip" and then "choose zip from sdcard". Search for the zip file and press OK then go to "YES" and press OK. Wait until done.
Go to "wipe data/factory reset" and OK. Go to YES then OK. Wait until done.
Press "Reboot System Now" and "yes" if asked (if you are asked about some fix or anything after you press reboot now choose the positive thing like the answer that is not no).
OPTION 2.
Copy the file using adb push. Open a CMD window in Windows (Start+R type CMD press ENTER). Copy this:
Code:
adb push
With the space. After space go where you downloaded the zip file highlight it and drag it in the CMD. Leave a space after that and type /sdcard (without space after).
Wait until done and close CMD.
After you copied the file to your sdcard go to "install zip" -> "choose zip from sdcard" -> search for the "P710 Stock KK.zip" press OK then go to "YES" and your installation will beging. Wait until it is done. Go to "wipe data/factory reset" and OK. Go to YES then OK. Wait until done.
Press "Reboot System Now" and "yes" if asked (if you are asked about some fix or anything after you press reboot now choose the positive thing like the answer that is not no).
NOTE: In the zip i made i don't know why i couldn't sideload it but usually you do not have to copy to SD card to flash something. You can sideload it. All you have to do is:
-Go to "install zip" -> "install from sideload"
On your computer open a CMD and copy this :
Code:
adb sideload
Copy with space and after what you copied grab the zip you want to flash and drag it to CMD. Hit ENTER. Sideload will send the zip to phone and process of flashing will start. After it is done reset to factory again.
Press "Reboot System Now" and "yes" if asked (if you are asked about some fix or anything after you press reboot now choose the positive thing like the answer that is not no).
CONGRATZ YOU ARE NOW ON KITKAT. I HONESTLY THINK THAT YOU SHOULD GO FOR THIS CUSTOM ROM OVER HERE BECAUSE IT IS LIKE 10 TIMES BETTER THAN THE STOCK KK. TO INSTALL JUST DOWNLOAD THE ZIP FILE FROM THERE (V2) AND FOLLOW THE TUTORIAL WITH JUST REPLACING THE ZIP WITH THE OTHER ZIP.

6. Flashing Root through CWM.
On some ROMS root will not be there. To avoid this we will flash the SuperSU zip.
To get to recovery you have 2 ways:
- From you ROM connect USB as MTP or in a way that ADB recognizes it (device gets detected by adb devices) type adb reboot recovery.
- Close your phone. At the same time press VOLUME DOWN + HOME BUTTON + POWER BUTTON. When you see the LG logo stop pressing POWER BUTTON. Keep the others 2 until you are in CWM.
Install the SuperSU zip with one of the ways you learnt at step 5.
You are rooted now.
Hope everything worked out fine for you and you are happy. Have a really nice day.

Does P713 have NFC?
This method actually works for dual sim too,you just have to use P715 kdz's.

Yeah it does. Maybe this weekend I will mod it. It is usefull for recoverying from soft bricks also just Step 1 and 2.
it was great till i get stuck on boot loop ,,, now how to solve ?
thanks for the useful guide.
I have a problem though, I cannot go after kdz extraction.
LG Tools stops with an cryptic error like [009.400.120.120.120]PC????? and looking at the log it seems there are troubles in unpacking the kdz file.
I have tried with different roms but still the same.
Does anyone has the same problem ?

I can't really understand you. The point of this guide is to get root on kitkat so flashing with lg flashtool will not work if you want kit kat rooted. I tested that V10J on my own l7 2 (p710). Also if you flashed Jellybean did you press CSE Flash not Normal Flash?

Ok do that step again. Flash with that tool using the image i provided. After the last ok. Even when you get the offline error don't touch it until phone reboots. If you get bootloop do this.
1. Pull out battery. Wait 10 seconds. Push battery back in.
2. While holding POWER DOWN + HOME BUTTON press POWER BUTTON. Wait until you see LG logo then stop presing POWER. You will get to see android guy doing stuff. Then tell me if it's ok.

Don't forget to press the thx button it's in the right . I will add this to the tutorial I didn't need it but who knows.
I managed to do the "root" step, but somehow cannot proceed with the next step.
When I check "USB debugging", the phone doesn't connect to the computer for some reason. I tried multiple computers, with no luck. The "adb devices" says just empty "List of devices attached".
If I disable the USB debugging, the phone gets connected just fine, if I enable it again, it gets stuck on "Connected as installer", and doesn't connect as MTP....
Any idea how to fix this?
Do you have drivers installed? Also when you press MTP cancel if your phone wants to install anything.

I tried everything, without luck. I ended just using terminal emulator to copy the files on phone directly (might be cool to add this to your tutorial, as someone else can also have this problem). So, now I'm on Amigas ROM - makes a HUGE difference! Thanks, looking forward for some other custom ROMs for this phone..

Strange huuummm. I don't know. Yeah i will add Terminal Emulator also in weekend. Never happened to any of my phones before... Maybe driver conflict on your PC or something like that.
Hello,
I recently attempted to root my Huawei Honor 9
I was able to successfully unlock my boot loader and (i think) install TWRP. I used a CMD command to reboot it into recovery mode, although from here-on out things went very bad. Here are some problems that I have been having
1) I CANNOT get out of TWRP. It says that I have no OS installed. Everytime I reboot I am greeted with the TWRP application I attempted to install a custom ROM, although now I am getting many errors [such as failed to mount '/cache' (invalid argument)]. These errors show up for everything I do, such as attempting to wipe my phone and also installing ROMS
2) My phone no longer shows up on my PC, although I have been able to use my micro-SD to transport files to and from my phone to my computer
3) The internal storage shows up as 0MB
pls help
many thanks if you can

Shutdown phone, connect USB cable to phone and press POWER plus Volume down button. This will bring you to Bootloader, use HWOTA script to upload stock firmware.

You can follow this guide:

Note:
I recommend you follow the second link, it will be easier for you. Get external SDCARD, copy UPDATE.APP in /dload folder and instead of dialing on phone (which you cannot), use enforced update:
Step 1. Copy the entire dload folder (with UPDATE.APP in it) to the root directory of the Micro SD card. Check the file list is right.
Step 2. Make sure your handset is power off. Insert the Micro SD card into the handset.Press the VOLUME UPandVOLUME DOWN key, and then press the POWER key to power on the phone and enter the Software Upgrade Mode.
Step 3. When the progress bar stop, the phone will restart automatically.
