I have yet to find an answer to this while searching for the past day, so I'm going to ask about it here.
My LG Optimus V's (just got it a few days ago as a birthday present) screen seems to be permanently blank... In case someone asks... yes, it is activated.
What Happened:
I rooted the phone using Gingerbreak 1.2, installed rom manager/clockwork recovery mod, then attempted to backup my phone in case something went wrong. However, when I started the backup, I noticed that the screen was completely blank. I was kinda freaking out, so I just took a shower while it did it's thing. When I came back, it was done creating the backup and it showed up in Rom Manager. After toying with some of the things I can do with it rooted (I only rooted it to see how much of a difference it would make without changing the kernel), I decided to recover that backup. When my phone restarted to recover the backup, the screen was blank once again. After waiting for over an hour, I concluded that it must have finished (since my HTC Hero would finish restoring and never reboot until I tell it to) and took out the battery. Afterwards, it would show the LG splash screen... then the blank screen.
What I Did:
I was thinking about the android screencast java application a few hours after my problem first developed. I plugged my phone into my computer, got adb working, and android screencast showed me that my phone was actually getting stuck at the clockwork recovery mod screen. I tried many things... I installed a CM7 rom, flashed 3 different recoveries, flashed an overclocked stock rom, etc. Eventually, I flashed the stock rom (no changes whatsoever) and stock recovery. Now I can hear my phone, but cannot see it. However, I should note that while using CM7 the same thing happened. The only difference being that I could use android screencast to see the screen (the phone was actually working) with CM7. Now with the stock rom, adb is disabled and I cannot see the screen or do... anything.
What I Think I Should Do:
I'm thinking about calling Virgin Mobile and telling them that my screen is defected. If they see the issue they'll probably think that it's a hardware issue (for all I know, it could be) and they'll probably give me a replacement. However, if anyone as had the same problem and fixed it, I would love to know.
I would love you hear your opinion on this and, if possible, a fix. Thanks in advance!
(JIC, if I posed in the wrong section, I'm sorry...)
you poor souls reporting the symptoms of getting the newer screen hardware from the optimus s in your v's don't number in the double digits yet, but it's getting closer.
I posted a fix on AndroidCentral, see it:
here
good luck! the fix has worked for everyone I pointed to it so far.
btw, the screencast idea is excellent!
crud. stock recovery, you may be SOL.
you'll probably have to boot into custom recovery to use screencast or adb now.
use the unplug phone -> pull&replace battery -> hold home+volume down -> keep holding, press and hold power until lg screen goes blank to enter recovery. maybe adb will work in stock recovery, I dunno.
Thank you very much for the reply!
Yeah, you're right, I'm probably SOL... I still have one option though! Theoretically, I should be able to turn on ADB without being able to see my screen. I know how to access the settings without seeing it, but navigating myself to the "Applications", "Development", "USB Debugging" may be a little hard. I will attempt to do so. I will report my progress in a bit.
However, if you (or somebody else) could provide screenshots of a step-by-step process to turn on USB Debugging in the stock rom (since it's kinda hard to do remember where everything is and screenshots of different phones is kinda different) then I would appreciate it VERY much!
I shall update this in an hour or so.
UPDATE (9/2/11 - 9 PM):
I'm going to take a break for now. Good thing I give everyone my Google Voice number, I doubt anyone will notice a change. I'm going to flash a stock rom onto my HTC Hero so I can figure out where things are on the LG Optimus V (Same screen size) in an hour or so. I'll update my progress in like 2 hours.
UPDATE (9/3/11 - 8:10 AM):
I have been unable to turn on USB Debugging and it seems to be because I don't know where the confirmation after turning it on is located. However, I should note that when I boot into (I think) recovery, "adb devices" states that the device is attached but offline. If there is a way to make it "online" from stock recovery then I would love to know. For now, I will try everything I can.
UPDATE (9/3/11 - 8:22 AM):
Ok. I plugged my phone into the back of my computer and now when I do "adb devices" it detects the device in recovery mode. However, when I try "adb shell" it says "- exec '/system/bin/sh' failed: No such file or directory <2> -". I'll try some more stuff, but does anyone have any idea of what I can do? Android Screencast doesn't work either, so that's not an option.
UPDATE (9/3/11 - 9:42 AM):
Crap... now it's indefinatly booting into recovery... I had something like this happen before, I'll report my status in an hour or so...
UPDATE (9/3/11 - 12:36 PM):
My friend finally got my phone booting out of recovery again! Now all I have to do is get "USB Debugging" on and it SHOULD work!
I <think> there's a key combination to power up into the bootloader. if you can find it with searching here and android central.
I haven't been able to track that down today. If you can get into the bootloader, you can fix it. Search for asadullah's fastboot root instructions here if you find a way to get into the blue screen (the bootloader, which fastboot talks to.)
otherwise, I'll be done taking the kids to the (ugh) pool in a few hours and I'll search more.
try pulling your battery for a few minutes and see if the reboot cyle stops that way, at least it might get into recovery or the rom.
glad you got back into recovery again, not too sure how to help at this stage though, since I can't find a way to get into the bootloader with a power-on key combo. just emergency mode (useless to the V since the firmware from LG is missing a file) and safe mode. boo.
there is a youtube video for enabling usb debugging on the v, maybe it'll help you find the right spots to press.

edit: you can also try to reboot into the bootloader with adb, even though it's missing the shell... it's worth a try, and if it works you can flash xionia recovery with fastboot and things would be a lot easier from that point.
Code:
adb reboot bootloader
if that works but you need more help, a battery pull is the only way to power off with the bootloader except "fastboot reboot" will try to boot your rom.
Awesome, thanks for the replies! I'm going to try your suggestions now. I'll let you know how things work out in a few hours. I would have replied earlier, but to my satisfaction there was a surprise party planned for me, lol. I will defiantly try these out now.
Once again, thank you very much. I honestly did not expect a reply for something that happens to such few people.

Click to expand...
Click to collapse
I'm honestly not sure what my friend did, lol. She was just messing with it while it was, apparently, in recovery and it ended up rebooting and loading the rom. I, honestly, don't want to risk getting stuck in recovery anymore since taking out the battery for an hour didn't do anything... If I'm unable to get adb on using what I know from that video then I'll try booting into the bootloader. Like I said before, I'll report my status in a few hours. I really appreciate your help up to now!
EXTREMELY HAPPY UPDATE!!! (9/4/11 - 1:22 AM)
I was able to turn on ADB! I used what I learned from that video and how turning on ADB works on my HTC Hero to get it working and it's FINALLY ON! Now I can attempt to flash the recovery, kernel, and everything else in order to get it working! Thank you VERY much! I will let you know how everything turn out
Another Wonderful Update! (9/4/11 - 2:03 AM)
I have flashed the recovery.img (the Xionia CWMA one) and can see my screen in recovery! I haven't seen anything on my screen besides the LG splash screen so I'm overwhelmed with joy! I'm flashing a new ROM and the other stuff now!
Final Update! (9/4/11 - 2:09 AM)
2:05 AM - I see the rom's boot screen!
2:06 AM - I see the CM7 Mod boot screen!
2:08 AM - I see the UI on my screen and everything seems to be working! Thank you VERY much!
Quick question though... If I want to install a new ROM, do I need to flash the xionia anykernel one directly afterwards?
ah, excellent! glad it's working now.
you're the most persistent (and maybe technically apt) person I've helped with this so far.
I still think that using screencast was the best new idea I've seen yet.
yes, you'll need to flash the xionia kernel after flashing any rom or rom update.
roms come with their own kernel in the boot.img, and none of them currently out for the v have the video drivers from the newer sprint kernels.
right now, xionia kernel is the only thing that works.
and, you'll need to flash the key swap after changing roms, as well, but at least forgetting to do that won't take out your display.
now that you've got xionia recovery on your phone, it should be a lot easier next time.
Thank you for both the help and the compliment!
I don't like giving up when it's something I know I can do. I figured that if I was able to mount my SD card without being able to see the screen, I should be able to turn on USB Debugging as well. About the Android Screencast... I didn't actually think about it until it until I plugged in my phone while the screen was blank, ran "adb devices", and saw that my device was detected within recovery. I figured that I might as well give it a shot... and it worked.
Alright, that's what I figured. Hopefully someone realizes what's happening with refurbished Optimus V smartphones and ports the newer sprint kernels to the Optimus V. I feel like I got ripped-off though... I bought my phone "new" and got a refurbished one. I can't really do anything though, we're not technically supposed to be rooting our Virgin Mobile phones anyways, lol. I'll be sure to do that everytime now though. For now, I think I'm good with the Bumblebee rom.
Once again, thank you VERY much for your help! I know I would not have been able to fix my phone without your help.
EDIT:
Oh yeah, btw, if the Optimus V ever gets stuck in stock recovery, press the "back" button then "home" button to boot into the rom. Not sure why it works (I was never able to see the screen), but it worked.
There is a key combo!
First time caller long time listener... I bricked my own Optmus V with a bogus ROM. To boot into recovery without adb press (Home)+(Volume Down)+(Power) Now rocking CM7!
I have an AT&T HTC One I bought off swappa. It was fully converted to the Google Play Edition. About a week ago I clicked install update when it popped up (dumb probably). It rebooted and showed a "no command" screen with a keeled over android guy with his stomach open and a caution sign there.
I took it to Seattle Android Guy who tried to get it all stock by locking the bootloader and turning s-on, but it wouldn't take it because the bootloader was still the dark bootloader. I took it back home and managed to get TWRP Recovery on it, but it won't take any of the roms I try to flash over to it or install via TWRP. I am pretty new to everything so if you have a solution, the more detailed the better. I've read that it's possible it is bricked, but I really want to keep looking for a solution. I paid almost $400 for this device and only got a couple weeks use out of it. Any suggestions, ideas, or help would be greatly appreciated.
Thanks.
Ok, first up I know there are many posts out there about this issue because I've looked at most of them and tried them so please bear with me.
I have a Samsung Galaxy GT-N8010, about 4 years old. I have never rooted or done anything to the firmware in all that time except OTA updates & the occasional factory reset to clean things up.
Couple of months ago it was on, i had been using it and put it down and when i came back it was on the Samsung logo screen and has been ever since.
Since i could get into the download page even though it was already bricked I figured i'd try rooting to see if i could fix the problem. Now possibly i should have attempted to get into recovery mode first but I attempted to install CWM (as per posts here). It appeared to install fine. But no recovery partition, screen blinks and goes back to the logo.
I've tried flashing stock firmware, TWRP, CWM - all 'appear' to install successfully according to ODIN, but nothing changes, still stuck on the logo screen.
So does this sound like a hardware issue or am i missing something? The Tab A 10.1 with s-pen looks great, would be a perfect replacement, but is not available in NL
Thanks guys (& gals)

Hey,
I'm pretty new here, so don't hate on my lack of knowledge^^
Maybe I'm even in the wrong sub-forum
(I think there was a sub-forum dedicated to moto x, but this isn't a device-specific issue, so here should be fine - no?)
Got the following problem:
My moto x (2nd gen) is stuck in a loop. I get to the logo-screen, then it goes to "Encryption unsuccessful" and when I click "Reset", it restarts and fails upon trying to reset.
How I got here:
1) A while ago I wanted to encrypt the phone for the lulz (using its' own encryption-tool)
Followed the simple steps, as in having it charged up, but the encryption did not go through.
Don't remember having it to reset at first, it just booted, even though it had bugs after that:
-whenever I charged it, I had problems turning it back on after charging, had to turn off and back on for it to actually work.
-those notifications on top which one can normally open via sliding down, that sliding down did not work after that.
Eventually I did a hard-reset and it fixed the sliding-problem.
Charging also worked fine at first until it did not.
2) I ended up stuck in a boot-loop that went to the logo-screen back and forth (got to logo-screen, restarted, got to logo-screen, restarted, ...)
Tried to soft-/hard-reset using the VOL- and POWER combo.
The hard-reset itself threw some errors at me, something like "can't delete [whatever]".
Still, after a few tries it eventually went past the logo-screen to the encryption-step.
After another few failed resets and emptied cache via recovery-screen, it somehow ignored the encryption-step and turned on the phone (was a fresh version).
3) Worked fine for 1 whole evening, no crashes/glitches/anything until I had to charge it up.
Then it was back to the broken state.
Note: during 2) I tried to boot with a custom recovery-mode(TWRP), but couldn't get it running.
Then I tried to flash it, but anything I tried to install failed.
I had my suspicions, but eventually I got it straightened out: my phone isn't rooted, and the bootloader is locked.
I did get the code to root it via some steps and the motorola service, but the code did not work as it wanted me to unlock the phone first.
From what I've read, to do that I need to get into the settings and unlock/root it...
Funny thing: I can not turn on the phone to get into the settings.
So - anyone got ideas?
Warranty is gone since apparently my tinkering with the locked bootloader and unrooted phone still was visible and they voided the warranty.
Not sure I broke much/anything with that, though, since it DID work at some point after that (even if it was for a few hours before needing recharging)
Therefore I'm open to any suggestions since the alternative stop would be throwing it into the bin^^
Can I unlock the bootloader without having a working system?
Can I root it somehow without having to get into settings (since I can not turn it on in the first place)?
I did a fair share of reading, but most times the guides just assumed that I already rooted it, or forwarded me to a guide where it said "go into settings and spam the build to get advanced options, then simply root/unlock that damn thing". Tried to find a way to unlock/root it without being able to turn it on, but did not get lucky with the search.
If I could unlock and root it, I probably could go from there. Guides are pretty specific and seem to work for most.
Also, I would try the original android version first before searching for any custom systems.
(that is the smartest way to do, right? since I'm just a user and dont plan on doing more hacking/breaking)
Hope all that above wasn't too much to read
Thx for any advice in advance.
Edit:
Well, after what feels like 50 restarts it miraculously did not send me to the "Encryption unsuccessful" but instead booted like it should (as a fresh version, though - so had to backup).
Now I've turned on the thing in the settings so next time it breaks, which I expect to happen by tomorrow, I can flash that sucker.
Still - anyone knows how to enable all that stuff one normally does via settings some way that does not involve successfully booting it?
I mean, there should be a way to root/unlock it without having to turn it on first, right?
Edit2:
As expected, the flashing part was pretty easy, so I'm now sitting with a fresh android 6.0.
Two days in and it's still working fine, haven't had any complications (except battery draining faster then at the very beginning, but I think that's due to it hanging too much on the usb-cable during all those sessions of me trying to fix it - and generally I've had it charge over night a few times to often)
Still would appreciate any advice on how to unlock developer mode and usb-debugging within the bootloader or recovery-mode.
So I admit I am an idiot and did this to myself. I installed the latest FireOS OTA through TWRP then thought to keep TWRP I would install it before I rebooted. I know I probably should have read threads about keeping root and the horribleness of 5.6.0.1 but I did not. So I can boot into the OS and I can boot to bootloader but I have no recovery at all. Any one know how to recover from this? Found out the unbrick method I have used before does not work. Fastboot give me an error about locked hw.
Been working on this anyone know or have a fastboot zip or image. I am getting a errors trying to flash the amazon bin with fastboot.
I know I am the only one posting here. I read through a bunch of threads that seem to be people in the same issue. I have now managed to get it stuck in demo mode. I also cannot seem to accomplish much from fastboot because I get a locked hw error. Bought a couple for parts HD6s off ebay. So hopefully I can make something work and get at least one working tablet. This has really put a damper on trying to create a device tree to try and build cm12.
Closer to being a brick. Some how I managed to have root in adb and managed to wipe all. Which I guess really meant all. Now all I get is the amazon logo. No desktop. No adb. No way to get to fastboot.
So ebay tablets came in, bout a lot that had 2. The one was listed as a demo model, so a simple ;demo in the search and resell the device and viola fully working tablet. It still had 4.1.1 on it so a simple update to 4.5.3, Kingroot, and TWRP install and back on CM11. The second was "black screen" so I assumed bricked as it did not seem to turn on when plugged in, initially. Tried running through unbrick but nothing from ./reader.sh so assumed on newer FireOS that blocked that function. After setting the first up I was rearranging my stack on now 2, what I thought where, badly bricked devices. Hit the power button and booted to lock screen with 7% battery. So I now have an extra HD6 to mess with. Best part is I got both of them for $20 total.
