[Q] Lg Optimus V (New screen) Help! Black screen, no adb shell, some recovery menu - Optimus One, P500, V General

So i have been stuck at the black screen for days. Searching online for answers and no luck. I am on the brink of just returning but i won't give up yet. So i got the new lg optimus v on black friday and rooted it. I installed busybox and superuser and clockwordmod. I put recovery from clockwordmod. Then being dumb at the time, i clicked factory reset. Now, i get black screen after the lg logo pops up. I look online and use androidscreencast. I use that to find out that i have recovery, but i can't see it because of those hittachi drivers. So, what i do is these instructions
Nandroid Instructions:
1) Extract the "BCDS-20110203-0357" file into the "nandroid" folder, under the "mem=477M" subfolder.
1a) For Clockwork Recovery, place the "BCDS-20110203-0357" file in /sdcard/clockworkmod/backup
2) Boot into recovery
3) Go into the "Backup/Restore" menu, and select "Nand Restore"
4) Allow it to restore
5) Reboot! System should be stock
6) Go below and flash stock recovery
Recovery Instructions:
1) Download flash_image and the stock recovery and nandroid back up
2) Extract stock recovery.img and flash_image to the root of your sdcard
3) Open up an adb shell, or terminal emulator on your phone
4) Enter the following codes:
flash_image recovery /sdcard/recovery.img
reboot recovery
right so now it worked. i then flashed a new rom i think. reboot and it works right? WRong. It loads up but I CAN"T SEE IT. I can hear the virgin mobile saying and androidscreencast shows me the android logo before crashing on me.
So i find out that i can do everything on it but can't see it. SO i go back to recovery with the 3 finger method. home + volume down + power. So then i decide to flash a new recovery.
So i go to adb. I type adb devices. IT shows my device and says its in recovery. Now i can't see it. So i try to use androidscreencast and it comes with an error.
Error attachment at the bottom for androidscreencast.
So i skip that and go back to adb. I try my last hope and try adb shell. Now that comes up with an error.
Error attachment at the bottom for adb shell issue.
Please if anyone could help with good detailed instructions. I don't want a link, some of those are super confusing. I need a good step by step instructions because i may be missing something and i don't know if that is the case.
EDIT: So i started with clockworkmod recovery menu some werid version. Then i put the recovery i was given here . Then after that i flashed this stock optimus v. The new recovery i flashed did not get rid of the black screen, i was still using android screencast. So, now when i boot up into "recovery" i don't know what to press or do and since android screencast + adb aren't there for me. I will have to do it blindly, but i need help.

Sorry to bump, but anyone help me?

To see if the recovery flashed right but isn't visible, boot into recovery, wait about one minute, press camera, then menu, then home. Depending on which recovery those are the select keys.
if the phone reboots after pressing those keys, the recovery works. Otherwise it didn't install right.
You can try
adb remount
Before
adb shell
to maybe get /system mounted for a shell prompt if recovery is broken.
Problems: the stock backup and recovery you flashed are for older ov's with a different screen driver, and stock recovery isn't rooted. Adb remount may not work unless you flashed the right stock zip.

Ok i booted into recovery with the volume down + home + power button and let go when the lg logo popped up. I waited for 1 minute. I pressed the camera button first. No go , nothing happened. Then i pressed the home button (The button with the house on it). It then rebooted into android with the virgin mobile saying (I could hear it) So, recap I pressed home button and booted into black screen android couldn't see anything. Going to try adb when i get home.

if it's stock recovery, adb will not work. if it's xionia recovery (might be, with the home instead of menu being select) you'll be ok with adb probably in recovery. if it won't work it'll say 'device not present' or 'connection refused.'
you'll probably have to turn on usb debugging blind in the blacked-out rom install to use adb to fix the recovery. Someone I helped with this some time back used a youtube video (here's the post) to find the right places to press on the screen to do that, then he was able to use android screencast to see recovery on his pc and fix it that way. if you can get debugging on, you can also use adb to fix it.

UPDATE: I did it. I turned on usb debugging with the black screen. I got android screencast and ddms. I can see the screen through android screencast. Now i have no root. So .
1. Root i want a good root for Lg Optimus V (New Screen Hittachi Screen)
2. How to flash working recovery that i can see . I want direct link to the recovery so i don't screw up.
3. How to flash working rom that i can see. Same thing direct link i ain't screwing up now.
4. How to flash a working stock Lg Optimus V New screen rom that i can use.
5. Do i need a new kernal or just working recovery???

nicely done.
you'll have to use screencast several times, then it'll get easier.
you'll need a few apps from market.
oi file manager to install apps from card.
flash_image gui to flash recovery
you need to check "allow install of non-market apps" under settings>applications
download gingerbreak 1.20.apk from here
copy it to your sd card. find it with oi file manager. click it and select install.
then run gingerbreak.
if you're lucky it'll work first try.
some people have had better luck using gingerbreak with the phone plugged into a pc.
it might take many tries if your phone is stubborn.
after it reboots, you can use flash_image gui to install this recovery
it's up-to-date and made to handle new or old screens.
then go to the iho thread herefor a gingerbread 2.3.7 rom, or Harmonia here
for froyo 2.2 rom.
both work without tweaking on your new screen.
both have install instructions in the linked threads.
after flash_image gui does it's thing you can turn off the phone and reboot into recovery
hold home+volume down, then hold power too, until after the silver lg logo goes away.
you could make a backup, it's normally advised.
use camera button to select.
good luck!

Thank you Very MUCH!!!!
One question about flashing the recovery. Can i use adb or some other method of flashing that recovery. Like say adb. I saw this somewhere wondered can i use this instead of flash_gui apk.
# su
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system
# cat /sdcard/flash_image > /system/bin/flash_image
# chmod 755 /system/bin/flash_image
# mount -o remount,ro -t yaffs2 /dev/block/mtdblock5
# flash_image recovery /sdcard/recovery.img
# reboot recovery
Just wondering, it would be easier for me.

Yes, definitely.
you'll need flash_image copied to the card like the recovery for that.
just change "recovery.img" to the actual recovery filename, or rename the recovery itself to recovery.img first.

Thank You agian very much! I got everything working and i am running CM 7.2. Very happy that i don't have get another phone. Very very helpful.

[TOOL] Viewpad 7 Backup, Root & Recovery

In order to install custom firmware on the Viewpad 7 and equivalent devices (Cherry Mobile Superion, Commtiva Linx N700, Olivepad VT-100, Spice MI700, and Camangi FM600) you must use an alternative recovery partition. There are several methods to accomplish this, but in this thread I will document what I use personally.
For starters ALWAYS create a backup of your original 'stock' firmware.
Rooting:
1. Download version 1.7 of Super One Click. Some users have reported issues with the latest version, but previous versions can be found in the thread.
2. Place your Android device into debugging mode, and connect to computer.
3. Right-click the Super One Click executable and select 'Run As Administrator'.
4. At program launch select 'rageagainstthecage' exploit method, then select 'Root'.
5. If there is no activity for more than 30 seconds and the terminal display is stuck at 'Running rageagainstthecage....' remove the USB plug momentarily and plug back in.
6. You should get the message “***IF IT KEEPS LOOPING, TRY DISABLING USB DEBUGGING NOW***” followed by an ADB reset, waiting for device, and finally a successful rooting message. (Apparently the looping issue is a known bug).
7. Once this process is complete your prompted to test the root condition. Follow the steps to verify.
Stock Backup:
1. Open up ADB shell within a terminal.
2. Get the list of partitions:
cat /proc/mtd
3. Pull each original partition from the device onto the SD card:
cat /dev/mtd/mtd3 > /sdcard/recovery.img (example...change for each partition)
Install Alternative Recovery Partition:
1. Copy the flash_image and clockwork recovery image to your SD Card (Find Attached Below).
2. Open a terminal (via computer or terminal emulator). Enter ADB shell.
3. Within ADB shell enter the following to change permissions for the flash_image:
chmod 755 /system/bin/flash_image
4. Replace the original stock recovery image by copying the clockwork image in it's place:
flash_image recovery /sdcard/cwrecovery.img
Installing Custom Firmware:
1. Copy the custom firmware of your choice to the SD card.
2. Power down your device.
3. Depress both volume keys simultaneously followed by holding in the power switch for a few seconds.
4. Upon power up you will see the birds logo and 'enter recovery' text in the top left corner of the screen.
5. Use the volume keys to step through the menu.
6. Select 'Backup & Restore' followed by 'Backup' to make a 'NANDROID' backup of the current firmware. The backed up ROM should be located in: /sdcard/clockworkmod/backup/date&time/
7. Once the backup process completes you will be back at the main recovery menu.
8. Select 'apply sdcard: update.zip.
9. Once complete select 'reboot device'.
DISCLAIMER: I cannot be held liable for anything you do to your Viewpad 7 (or equivalent device). Make sure you are comfortable with recovery tools, such as ClockworkMod, before proceeding.

Installed, working ok. but the UP/DOWN button always jump 2 steps.
same. rooted. 2 spot jump on recovery menu. looks like pressing down moves one and then releasing the button goes another.

TNT Lite is for the gTab.....NOT the Viewpad...therefore it will not work. There are only a couple modified ROMs available at this time for the Viewpad 7. I made a mod to stock ROM which can be found in this thread:
http://forum.xda-developers.com/showthread.php?t=1008673
I believe there is someone else working on a Gingerbread ROM (as am I), but I don't know any details of they're progress.
As for the recovery menu navigation problem (moves two spaces instead of one), I think it came that way from the manufacturer (FIH). Not sure how to remedy it at this point.

May want to update the OP to reflect that one should be downloading SuperOneClick version 1.7, not 1.8. The latter doesn't include the RageAgainstTheCage exploit method and will not root the device.
Took me a few tries to get my new Viewpad 7 rooted, but it finally is.

I second that, took me a few tries also... Used SOC 1.7 and it was a bit confusing on my Win Xp (xp-home SP3) machine about VP7 drivers and its USB Mass storage state (should remove SD card in VP7 if you have it installed).
It finally worked when the " Synchronation Tool " was also installed and running off of the virtual "CD-Rom" that was installed when the VP7 is plugged in...
Anyways keep up the good work!!! Hope to see more updates/ROMs/mods/etc... for the VP7, I personally think its a solid device with the exception of the small internal storage it has...
Can anyone please help me? /system/bin/flash_image does not excist on my viewpad 7...

Thanks for pointing that out. At the time of writing the latest was 1.7. I will make the correction.

Have you installed an alternative recovery (like clockwork)? If so you will need to copy the original recovery partition over, and then copy the remaining original partitions over. You can perform these tasks using ADB shell, and by using flash_image for the recovery partitions. You can find more information on this with a quick search.
So...this might be answered in another thread, but since there's no subforum for this device, it's hard to tell, but I digress...
How do I get around the "jump 2 spots" issue when in recovery? I've got clockwork in there just fine now, but I want to back up my system before I do any more serious "playing" and since I can't ever get it to land on "backup and recovery", I'm not sure how to proceed. Thoughts?

This double-step issue when navigating the recovery menu is definitely an annoyance. To get around it and only move one selection just keep the applicable volume key pressed down, and then hit the power button to choose the selection.
Sweet...got the backup going. Now just need to figure out how to partition the SD card and get link2sd working. Appreciate your help!

You have to download the flash_image file from this thread (look in the first post), and copy it to your device.
This is what I'm getting:
Unable to chmod /system/bin/flash_image: No such file or directory

[Q] gtab rooting 101

I'm new to Android, my first step was to research hardware and functionality. The choice, you guest it, gtab!
Now of to the good stuff. I ultimately want to root and update my Rom to vegan5.1. So far I have downloaded cwv08, upload downgrade and vegan. The problem is that when I try to restart using power + volume +, I do see the open box screen but then it just loads tnt and resumes boot. There has to be a step I must be missing here. Like I said I'm new to grab and android. Where do I start?
To my understanding, power with volume + without cwm install will run the command file in recovery folder. Preharps u are missing the file, preharps u are not naming the file correctly; too little details provided to tell..
try reading : http://forum.xda-developers.com/showthread.php?t=865245
same box with green arrow
I too have installed clockwork. Downgrade the bootloader then try to reboot into clockwork using the + and power. The tab acts like it is going to enter recovery says "Detect recover key press
Booting to recovery image"
Then it goes to that screen with he box with a green down arrow coming out of it and a progress bar. When it finishes it reboots. Still at stock rom, no joy at all.
A couple things I have tried. Copying a new update.zip to the root of the internal memory and the sd card, reboot with and without the sdcard inserted, rebooting normal then trying to get reboot recovery with + and power, copying the cwm update and recovery folder into root. No joy each time it it is the update box. I have not tried holding the recovery keys down in the dark while chanting xda but I think I missed my chance for that working last Friday.... when is the next Friday the 13th?
Thanks for any help or insight anyone can give us.
Bednab,I could not have explained any better. This is exactly what happens with mine. Today I encountered another challenge. My gtab will not connect to my-fy on open iphone. I have to figure this out before my road trip next month.
and there was much rejoicing
I kept at this and finally found a solution. A post pointed me to the answer on androidforums about the command file getting deleted out of the recovery folder after a successful update. I opened the recovery folter on the g tab and it was empty so I opened the one from cwm and edited it to this:
--update_package=SDCARD2:/update.zip
This way it points to my external card where I had a few custom roms. Copied it to the recovery folder in the root of the gtab, reboot into recovery mode and much joy!

Help needed

Long story short, I messed up my phone while changing the partitions to EXT4.
EDIT: accidently clicked enter, let me finish the rest before posting!
My phone is more or less a brick now. When I boot up, it doesn't take me to the moto logo, instead I get a blank screen that looks something like this
Unlocked
PwrReason: SW_AP_RESET
OS will boot up in 5 seconds
Press a key to stop countdown
Available modes are:
1 RSD
2 Fastboot
3 NvFlash
yadada all you would find while normally booting while holding vol down.
-----------------------------------------------------------------------------
Volume up to select, volume down for next choice
Current choice mode is: (the mode I pick)
If I wait it out, it boots
Powering on BP
Cold-booting Linux
Reading ODM Fuse: 1
Then boots up normally - EXCEPT. my touch orientation is all off. It is lower then where I tap, For example I have to tap the menu button area to access the space bar while typing, and since the orientation is off, I cannot select the menu buttons.
I cannot flash a backup or a new rom because I cannot access my recovery, when I vol up on the android reocvery option it just scrolls down and resets the whole menu..
Help would be greatly appreciated, I am on a Bell Atrix, rooted/unlocked.
Another (possibly stupid) question, will factory resetting through setting->privacy brick my phone? I vaguely remember reading something stating that but I am not 100% sure if I read it wrong or something of the sort.
Update:
I have successfully flashed a sbf file but touch screen orientation is still off.. Any solutions?

[Q] Need help getting my E970 to boot

Ok, so I rooted my LGOG E970. I figured I better unlock it as well, so I used FreeGee and unlocked it. I tried to download CWM but it said it couldnt download file. So I thought I would reboot my phone. Now, all I get is the google logo, with the unlocked key underneath, and it then goes to the LG logo and back to Google and shuts off. I tried to hold down power and volume down, nothing, and power volume up nothing.:crying:
any ideas? Thanks in advance! I love this phone!
CJ
You too, huh?
I did this the other night, and when the CWM failed to install I went to download it myself... That's when I saw that CWM for geeb is 6.0.3.8, not 6.0.4.5 like FreeGee shows. (Looks like FreeGee has moved on to targeting G2 or another... Oops.)
I hope you backed up your EFS, because mine was screwed up and I needed to manually restore it from the backup I'd taken. (I've had my phone rooted for 9+ months, finally got fed up with stock and was looking to get onto a 4.4 ROM)
So here's what I did:
Held power button until phone was properly off (failed boot seemed to be a still partially on state)
Held volumn up first, then started holding power.
When phone vibrated slightly, I let go of power and kept holding volume up... You should be in boot loader now.
When your phone is in the bootloader, connect to your PC (Make sure you have the proper drivers if you use Windows; I use Linux which doesn't have the same nonsense setup for drivers like Windows does)
Make sure "fastboot devices" shows your phone and then type: fastboot flash recovery _____recovery file name.img____
Press volume down twice to select "Recovery", and press power once to select it... You should be booted into the recovery that you just installed.
Once you're in a recovery, you can push a ROM zip via ADB, flash, wipe data/dalvik cache and reboot.
thanks, Just a little more help

Yeah, the stock recovery won't boot if you try it either. I forgot to tell you that. If you drop in a custom recovery (TWRP or CWM), it will work fine and you can both create a backup of your data and flash a new ROM...
If you want to try to get back to stock, LGNPST is what you should try. But to be completely honest, I don't know if you can LGNPST from the state that it's in. I haven't tried, and I'm using a custom ROM now (the whole reason I unlocked the bootloader to begin with).
bummer

Yeah, I got that too. I don't know if I got it fixed due to changing ROM, using the suggested recovery from the ROM, or if it was due to me restoring my EFS backup.
I flashed the TeamWin recovery found in the PSX instructions. Then I flashed PSX + Latest kernel + Banks Gapps + Banks Google Camera + AT&T NFC fix + SuperSU. I manually restored EFS from an ADB shell while in recovery.
When I booted I had: LTE works, Wifi works, NFC works, Camera works, ART works... The only things failing for me are the following:
Cell provider shows up as "Maritime" (display bug; as mentioned, LTE works fine and I'm on AT&T)
Settings > Developer Tools > Geeky Process Stats (does nothing)
Settings > Lockscreen > Slider Shortcuts (crashes as soon as I tap the middle ring)
LogCat is spammed with "QCOM PowerLock: Failed to acquire lock" whenever my finger is on the screen.
/system/xbin/mount --bind doesn't work (neither does mount -o bind). It gets sorta half-way-there, because the target directory can't be removed, but isn't bound properly it seems.
Other than that, it's been fast and smooth.

If so, (Not sure if cm recovery us close to twrp, but if it is) then you should be able to copy the data folder to one of those and then flash a new Rom and then copy and paste some of the directories. Orr do a nandroid backup if /data, and then flash a new ROM and restore that data backup afterwards. They would have to be the same Rom as you have now though
Sorry it took me so long. Next time quote me so I get a notification

No, twrp that I'm aware if will not wipe data. Unlocking the bootloader will though if it's not already unlocked

Hold down a set of buttons (Not sure which ones for you, but force restart it and then switch to buttons to boot into recovery. Google the button combo )
How did you flash cmw recovery? Should be the same as that

I found this guide on how to flash twrp and root, you shouldn't worry about rooting until you get booted up first... As for the force reboot, I couldn't find out how to force power it off, so try some of the following:
- Take our battery (if there is a removable one)
- Hold down the volume down and power simultaneously for about 10 seconds (maybe less, maybe more)
- If there is a physical home button, try holding volume down, power and home. (Or volume up)
Once powered off (when the screen turns off, you maybe have to be quick before it restarts. If it does just re-power it off and try again) then hold down power and volume up to boot into recovery mode. You shouldn't need twrp if you can boot into cmw. But I do recommend it when we are finished...
You'll also need a custom (or stock) ROM to flash. I'll show you how to push to your phone with adb if mtp doesn't work in cmw.

Alrighty so if you have fill adb drivers than great, if not this should still work fine...
Download this: https://androidfilehost.com/?fid=673368273298958289
Has adb in it, ignore all the root stuff. So extract the file to your desktop and open the folder. Put your ROM in the folder and name it something easy like rom.zip (important it's not rom.zip.zip)
When in the folder, hold shift and then right click inside the folder and select "open command window here" and then type "adb devices" and make sure something comes up with a ton of random characters. If nothing comes up (make sure phone is plugged in lol) then install your phone's drivers. Then try again. Next type this exactly as follows (if you names it rom.zip)
Code:
"adb push rom.zip /sdcard/rom.zip"
**NOTE the space between rom.zip and /sdcard**
This should take awhile, depending on how big the file is. You should see a pulsing dash in the left side of the command prompt. It will stop blinking and bring up a new line when done. Now go into cmw and flash the file in your sd card (rom.zip)
Going to sleep, I'll reply early in the morning before school

Root.bat is for Samsung yes, but adb is universal. We aren't worrying about root
Since you didn't have adb installed this is a lightweight version so you don't have to install it. This is just the file link I had on hand
