So I have an lg g2x originally running gingerbread 2.3.3 and I went through this procedure -> http://forum.xda-developers.com/showthread.php?t=1259852&highlight=linux+g2x+root
Everything seemed to work as described except that the phone now will not boot. I get to the LG screen but then the buttons just blink and shuts down and tries to boot again.
I must have missed a step somewhere, though I am not sure where that might have happened. In any case, I would like to get this working or, at the very least, get the phone back and working.
I am running linux and do *not* have access to windows at all.
Which LG screen are you getting? The static one or the one with a moving green bar underneath it? Can you still boot into Clockworkmod Recovery or was that a no go? You need to give more detailed information so people can figure out at what point in the boot process your phone is rebooting.
I get that initial booting LG screen with the face and the letters LG, there is no green bar. It sits in that screen for 15 or 20 seconds then attempts to reboot. Well, thats what I assume happens. The screen goes black, the buttons along the bottom flash and then after a few seconds that white LG screen comes back and it does it all again. It never gets past that and never into CWM. I can still put it in the flash mode that allows nvflash to connect and do its thing, but thats about it.
If you have successfully nvflashed cwm. Then you should be able to get into cwm by holding volume down+power until it goes to a blueish LG screen. Then flash a rooted rom from there.
That is the easiest/safest way of rooting a g2x. If you haven't done this you can Google "nvflash g2x Linux" and find guides on how to do it.

Right, thats exactly what should happen. Unfortunately, its not what actually happens. During bootup I a can hold power + volume down all day long and get the exact same behavior. Its a bit disconcerting.
[solved]
Guys, I found the problem and figured I would post it here for future folks.
I was unable to start my phone plugged into the charge (both to the computer and to the wall). I had to have the battery in for this to get to a good place. I guess initial startup just took too much power.
So if you do this, after using the restore script. Press the power button and volume down hold both, then *put in the battery*. Thats what worked for me.
thanks!
One of my friend tried to root his phone using odin and a firmware for version 9023 while he has a Nexus S GT-i9020t. I've been looking for some hours, and I couldn't find any solution for that problems.
This post has similar symptoms, but still no answer: http://forum.xda-developers.com/showthread.php?t=1436199
Symptoms
- No backlight at all (seems to be a problem version amoled vs slcd, as I could read)
- Screen is upside down (but buttons, keyboard, etc still react correctly, only the screen display is upside down, so you get to have two phones next to each other to press the right buttons...)
- Can't get into download mode to flash using Odin and the correct firmware. When you hold both volume buttons and plug the USB cable, you get the first attached image. Green lines, nothing else.
What it can do
- Phone can get into the bootloader, but screen is very dim, as you can see in the second screenshot
- Phone can boot normally, you may take screenshots, place phone calls (while guessing numbers), receive phone calls, but the screen backlight stays off, so it's pretty hard to read anything. Tried to get to the display settings to play with the luminosity, without success.
- No problems using adb to send commands to the phone, or using fastboot to flash the device.
What i've tried
1. Downloaded original firmware image from Google, and tried flashing the device using fastboot. Tried 2.3.6 and 4.0.4 for Nexus S worldwide (i9020t) - over here: https://developers.google.com/android/nexus/images . Still no backlight.
2. Tried the One-Click Unbrick for Samsung devices. Installed drivers and everything, the tool return the result Success, but still can't access download mode, or fix the problem.
It looks like the graphic part of the phone is messed up, and i've got no idea on how this could be possibly fixed.
Any help would be greatly appreciated !
I think your AMOLED Screen just died or is going to die. If it is still under warranty, get it replaced. If not, look on ebay and buy a replacement screen. Its a do it yourself procedure. Or take it to a phone repair shop and they'll do it for you.
It's not under warranty anymore, it's 1 year and 2 months old.
I doubt the screen died, since problems started when he installed the wrong firmware. Can a bad firmware cause physical damage to the screen ?
I honestly need help.
I'm not sure what to categorize my issue under.
I am stuck in a screen with the green android and the spinning thing in the middle, with a progress bar, but the bar just has a moving animation, looks like it is moving to the left, not getting longer or filling up like usual progress bars.
I am unable to get to the boot loader or recovery.
The issue started after I flashed Cyanogen Mod 10.2 Stable.
it booted fine then, but when I went to use it, it would have a never ending cycle of app not responding at the part where it asks to sign in to cyanogenmod account. I got to settings without signing in by quickly sliding the status bar and clicked on factory reset.
From there it proceded to reboot and now I am stuck in the screen described.
I have tried all the button combinations, reset with pin, nothing will get to bootloader or recovery.
ADB does not find the device, also no devices found when try fastboot devices line.
I have also tried putting the firmware zip on a microsd, but nothing new happens either.
any suggestions appreciated.
** edited ** Issue is resolved. Turns out I just needed to wait longer (about 2 hrs) ... I did turn it off using combo of power and Vol -, left it off overnight, turned it on in the morning and left it alone. I finished whatever it was trying to do, and now CyanogenMod 10.2 stable is working great.
Hello, my Photon started acting up really weird. First of all, it was really slow. I thought it's because I had like 150MB left and it was nearly full data-wise. However, I erased most of the data, and left it with 3GB left. Didn't work and it got worse.
I have these stripes around the display (just at sides, not at middle), while phone is turned on. Doesn't matter if in system, or at boot logo. Doesn't matter, because whenever I get to system, I can be in system for like 1 minute, then every application starts crashing (Apex launcher, Google play, whatever you pick) and I basically can't get anywhere. Also if I go to sleep mode, phone is basically dead and it's pure luck when I will turn on phone again. I am trying every few minutes and it's worthless, because any time I get to system anyway, I crash after few seconds.
What to do? I was planing to install custom ROM yesterday, but never got to that, because this all started to act up. So what should I do? Reset system? Any other ideas? Is phone dead?
Sorry for bad english, no bully please.
Thanks in advance
Update - now when I am trying to start up my phone, I have just black screen with white lines in the middle. Then phone shuts down. I will give more info when I will be at home and can get phone on charger
Well definitely try to charge the device up. You might try re-flashing the stock ROM using RSD Lite... Although from your description I fear your issue may be hardware related.
Could turn device on. Apparently that black screen with white lines was just discharged phone. When I put it on charger, I could again boot into system and it was working until I pressed power button to go to sleep mode and phone is again dead. Will try to flash RSD Lite later today and will post what happened

Charge the device as much as you possibly can before doing anything with RSD. Ideally you should have at least 50% battery in the device when flashing anything.
This is really miserable. I can't really get into bootloader. Because phone after that 'crash' or whatever you want to call it is dead and I can't even see if it's turned on or not. Basically I am randomly waiting when it's gonna restart and then I just get into system. Even if I fully discharge it, it will have black screen with white lines first, it flashes quite couple times and then it will finally boot into system. Also I remember it was ***** in past to get into recovery. Can I do anything from system? Because as soon as I don't turn off my screen by power button, phone is working, though it has those lines on side of LCD (I will try to borrow camera from someone and post it here today).
I set automatic turning screen off for 10 minutes and I am really careful about pressing power button. Sucks there is only option for just 10 minutes, so I have to tap on screen at least for once every 10 minutes or I will not have working phone. **** my life, really.

Why can't you turn the phone off and charge it while off, or boot to recovery and charge the phone in recovery?

About charging it while turned off - Can't because when I try to turn it on again, it's roulette when I get finally bootloader logo and not black screen with white stripes.
And boot to recovery. Is it possible to like download some command prompt application and boot to bootloader from there? I know when I had my G1 (and when I actually understood android ) you could boot to recovery or bootloader via console. I have astro installed on phone, so downloading some console application and installing it shouldn't be problem.
Btw as we are speaking, I tried to call someone and I basically get same thing like when I am going to sleep mode, I get black screen and now I am just waiting, when phone will eventually want to restart itself.

Still sounds like some sort of a hardware issue, is the phone new to you?
You can certainly force bootloader mode, in several ways. When it's off you can hold power + camera and it will give you a choice of what to boot. When it's in Android you can do "adb reboot recovery" or "adb reboot bootloader" depending on where you want to end up. There are various apps which can also do this for you, if you are on the stock ROM but rooted.

Phone is not new. I bought it used about one year ago.
I am not entirely new to android, but I didn't have android phone for 2 years and then I got this one. So I am really pretty **** with android atm
I will try reboot to bootloader from some console application.
I am rooted, opened bootloader, stock rom
Finally got into recovery, what now?
Also, when I once booted to system, I downloaded some root checking app, and root apparently isn't here. Well cornholio told me it is rooted back when I gave him my phone to perform sim card mod, but whatever. However, I am in recovery, but device is not detected by RSD Lite.

Well reading back thru this thread, I was suggesting RSD Lite back to stock. I'm not really sure what you want to achieve tho, what your "final" goal is here.
I'm not even sure what kind of recovery you are booted into - stock recovery? CWM?
Either way, if you want to RSD the phone back to stock, you need to boot into fastboot/bootloader mode - not recovery. Just make sure the phone is charged up as much as possible before flashing in RSD.
Oh, sorry - misunderstanding from my side, thought I can switch to fastboot from recovery, oh well.
Also yeah, stock recovery.
To spread more facts - in case somebody would have similiar problems, when I try to just turn phone on, I have zero success what so ever. There's just this blank black page flashing every few seconds. However, when I remove back cover, I somehow force phone to load to bootloader logo, then I finally get chance to force phone to get to recovery. I will try to get to fastboot

Not sure if stock recovery has adb enabled, but if you have adb you can 'adb reboot bootloader'.
Otherwise do the power+cam trick I mentioned earlier.

Did you remove the getvar lines from the xml file...?
Yes
Weird. I only recall seeing that when people were trying to downgrade... but you are flashing 4.1.2.
The phone is in fastboot mode? What happens when you click "show device"? The "Device Properties" section is eerily empty.
I know it sounds shady, when I am coming back here again in few weeks, just been a bit busy lately, sorry about that.
However, somehow I got phone to flash it. The white graphical lines on sides dissapeared, however I got some new bug - I can't use phone in portrait mode, just in landscape - aka I need to swipe keyboard to have phone working. Also, that thing when phone completely stops working now occurs only when I am in that portrait mode, but I can restart phone this time.
When I finished this, it was midnight so I went to bad, so I tried to set up alarm, if it's gonna randomly shutdown like before and unfortunately, yes it did. I was waken up with this classical white line graphical bug black screen and had to reboot the phone. Oh well, managed to boot to system and it takes 5 minutes to fetch sim card (I have sim card mod from cornholio) and as I said, those white lines on side aka mysterious graphical bug is back.
Unfortunately for me, starts looking like real hardware issue now
