[Q] Help!!! Soft Brick and don't know what to do! - G2 Q&A, Help & Troubleshooting

OK, I managed to really really screw my phone up!!!
I installed a 4.4.2 rom (crDroid) and everything was working fine.... USB debugging on and rooted.
Next I started playing with LCD Density settings and managed to get get a device that won't show anything past the LG logo.... just a blank screen.
I have tried connect it to my computer and using adb to push a new build.prop to fix it, but I can't seem to get this thing recognized via adb anymore.... all I see is an "unauthorized" device and I can't see the screen (b/c it blank) to make any changes to actual device.
I am really really worried that I have completely borked this device.... PLEASE PLEASE PLEASE HELP ME!!!!

Another thing I should note.... I have tried many many times to boot directly into CWM (which I have installed version 6.0.4.4.). Unfortunately I think the LCD problem is killing me here.... I hold down the power+vol-down and then press them again when I hit the LG logo, but at this point the thing just goes blank.... I never actually see a CWM screen.
Again, thank in advance for your help... I am very very desperate and really have no idea what to do at this point.

OK, sorry for the freakout... I got this sorted out... it turns out I was following the wrong instructions on how to get into hardware reset mode.... for the vs980 you need to do the following...
1. press and hold power + vol-down
2. as soon as you see the LG Logo...
- release the power + vol-down buttons
- then immediately re-press only the power button
This should do it... some people were (I'm guessing for the other versions of the G2) were saying you needed to "re-press" both the power and the vol-down button and this was not working for me.

[Q] ?Bricked? LG G2 (D800) *Seriously Bad*

So I tried getting Cyanogenmod 10.2 for my LG G2 (D800). I did some stuff and ended up rebooting and getting this screen.
[650] Fastboot mode started
[700] udc_start()
http://forum.xda-developers.com/attachment.php?attachmentid=2403056&stc=1&d=1384904247
I used TWRP for backup, but can't even get into phone to do anything.
Also it won't come up on my computer when I plug it in with usb. I tried both my computers and they both had the drivers but the phone won't even connect to either pc. I could connect easily the day before though.
http://forum.xda-developers.com/attachment.php?attachmentid=2403058&stc=1&d=1384904247
I also got this while pushing Power and both Volume buttons at same time.
http://forum.xda-developers.com/attachment.php?attachmentid=2403059&stc=1&d=1384904390
What should I do? :crying: If you guys need more info or pictures just tell me, I'll do anything to fix my phone.
Hold power down for 15+ seconds. Then hold volume up and plug in USB. This should get you into download mode to kdz. May take a few attempts.

I see your using Utorrent you pirate! JK
It looks as if your phone has some life left, not really too familiar with D800. Have You tried the key combo to get into TWRP? Does the D800 have download mode?
Also did you by chance flash the wrong rom (different carrier)? Did you wipe the internal storage?
It looks like the incorrect ROM was flashed, it did not like your boot.img. You should be fine. Hold down the power button for +-15s as he said. During that time the screen should turn off, back on to the LG screen, then back off again. The phone should stay powered off. Then, hold the vol- & pwr buttons, releasing them when you see the LG screen. While still on the LG screen, press and hold the power button until you arrive at the LG factory reset menu. Press the power button to confirm a factory reset, which will actually boot you into TWRP so you can restore your backup.

I got it to work again! Thanks everyone for helping me, I'll try not to break my phone again :laugh:
Thank you for these threads

I have the lg g2 d800 as well and I also had a similiar issue. I wiped to clean for new rom and accidently before installing cm-10.2 I hit the reboot button. I just want to say thank you guys for all the knowledge base. Reading this thread fixed mine too.
I had similar issue couple weeks ago bad flash,no backups and unable to mount sd from custom recovery, the only way for me to fix this was to install rom via sideload, which was pain for two days.

Sorry to revive an old post, but this doesn't work for me. My G2 shows the same codes again. It will not go to the factory reset menu... How can I fix this?
Thanks.

[Q] VS980 Totally Bricked - no logo, no ADB, no fastboot

I had originally installed the wrong version of a ROM, D802 instead of VS980. Got stuck in an error with fastboot only, and I ended up following the directions here :
http://forum.xda-developers.com/showthread.php?t=2582142
But I must have messed something up. Now the phone does not start at all. Pushing power buttons does nothing, no buzz, no lights, no logo, no combination of power button, power button + volume down, all 3 buttons, plugged in or not, none of it seems to do anything. The only thing that DOES happen, is that plugged into Windows it shows up as QSHSHUB_BULK device, and that's it. So something in there is on, I guess?
Don't know what to do. Might be completely gone. Anyone have any ideas?
I dont have the intellect to help you now, but for future referance if you flash the wrong thing and end up in fast boot, just use the hard keys to enter your recovery. As opposed to trying to enter fastboot commands, and flash your backup, or a different rom.
Send a pm to xdabbeb. Hes pretty compitent with fastboot

[Q] How can I get into fastboot mode without volume key?

Hello guys, I'm new here and I hope you can help me out.
Let me make the story short.
My phone's screen broke and I replaced.
In that processes I lost the rubber that stick
to the panel of the volume. I was fine with that since my phone
in vibrate mode and I really don't use ring tone in my daily basis.
I tried to download Android 5.0 lollipop and flash it.
How did I get there? well since I did not have a volume button,
I downloaded an app that restarted my phone and got me into
fastboot mode without the key (I did got me where I wanted).
Then the problem was that in the middle of writing the .img
the freaking cheap bastard micro usb unplugged!!!
BAMM!! phone now is bricked, I cannot get into recovery/fastboot mode
since I cannot press the volume key and my phone is bricked.
I tried going through fastboot mode via my computer again,
but the computer doesn't recognize the device since it still
looping there forever at the google logo. I try installing USB
DRIVERS to see if I could do some "magic" haha. Got
error "This device cannot start ..." And still at the same problem.
I know I can get back to my recovery if order the part for the volume
key, I ordered the part to replace it, but trust me I was 3 weeks without
my phone and now this problem
Is there any way that I can get to fastboot mode to factory reset my phone
without volume key with a bricked forever looping a "google" logo ? :fingers-crossed: :fingers-crossed:
I appreciate any help.

Im not sure why your text is like this? But paraphrasing buddy comes a long way
Just hold the power button, until it dies, or just let it die in general since your volume button (You only need Vol down and Power) to power it off completely. Since your Volume keys are gone, the best solution is to wait for the replacement before doing so, unless you can get the contact keys to trigger the Volume button, you're in a loss atm. No OS or Volume keys means you can't trigger ADB commands or boot into fastboot. Just wait it out I guess?

I think I bricked my ZTE Blade C2 v809

Please help me. I am in a sort of panic right now.
I have a ZTE Blade C2 v809, sold here in Portugal as Meo Smart A12. It was rooted and working fine. I was however getting some error 24's trying to install apps. I thought this might have had to do with using Titanium Backup to remove TouchPal (I did make a backup first), so I decided to restore TouchPal. There were however some errors in the restore and it was stuck there, so I decided to reboot the phone.
Chaos. Now it wont boot. If I press the button normally, the phone boots, I see the android logo, the screen goes black (Not shutdown black, a sort of light black background) and nothing happens. If I try to boot into Recovery mode by holding the power button and the volume down key, I just get the android logo stuck there, nothing happens. If I hold the power button and the volume up key, I get the picture of that laying down android with the message error.
Any more info I must provide please tell me, I am desperate for a solution, If I lose this phone I wont be able to get another one.
Okay I fixed it. Turns out the recovery menu DID work if I waited for a long time and tapped the screen. Used the update.zip available from the site, and it works like a charm
Yay, I bricked my phone, too.
I did something similar, changed recovery-from-boot.p name to recovery-from-boot.p-bak and install-recovery.sh to install-recovery.sh-bak
Now the phone doesn't boot properly, in fact it's stuck in a boot loop:
>starts
>shows white ZTE logo on screen
>restarts
Tried connecting the phone via USB cable and used fastboot devices & adb devices commands, no devices found.
Also tried pressing "power + vol down" and "power + vol up", nothing. I can't enter recovery mode or bootloader.
Apparently the remaining way to get in it's trough the SD slot, or maybe there's another way.
I kindly ask for help, couldn't be possible that I ruined this cell phone so fast.
Ideas, somebody?

N7 (tilapia) stuck at logo - no fastboot access ...

Hello everybody,
I hope somebody can help me to save my N7 (2012).
I installed TWRP without problems and after that I tried to flash a custom rom - which, for some reasons, didn't work.
After reboot my Nexus is stuck at Google logo with an opened lock at bottom...
I can't get to fastboot because when I power on while pushing VOL - button it just get stuck at the same logo screen.
If I keep power button pressed for about 10s, it shuts down but after a few seconds it boots again just to get stuck again at the logo screen...
The only way to shut it down completely is to keep VOL+ button pressed while pressing the power button.
My Windows 7 computer won't recognize the N7 at all anymore, but when I shut it down completely (Power & VOL+), windows says "Unknown device".
Is my Nexus still to be saved or I can throw it away?
Thank you in advance for each advice.

Hi, Conrad-007...
This is very strange - your Nexus 7 is clearly 'bootable' (sort of), with a functioning bootloader, ie., it's not hardbricked... or you wouldn't be seeing the Google logo.
In the distant past, back when I used to experiment with custom kernels on my Nexus 7, it sometimes required the POWER BUTTON+VOL DOWN buttons be pressed and held down for a good 30 seconds or more, to generate the necessary 'interrupt', and force the device into the bootloader.
My first instinct, is to suggest you may possibly have a problem with your VOL DOWN button, and maybe it's stuck somehow or not making contact.
It also occurred to me, that you might be able to access the bootloader with...
Code:
adb reboot bootloader
...or possibly...
Code:
adb reboot fastboot
...and even...
Code:
adb reboot recovery
But unfortunately, I'm pretty sure you need to be running fully booted Android or booted into a custom recovery (eg., TWRP) before you can issue ADB commands. I haven't tinkered around in this area of Android for a couple of years now, so my memory of the specifics is a little hazy.
Anyhow, here's a fairly comprehensive listing of Nexus 7 button presses/interrupts, which maybe of some use...
https://forum.xda-developers.com/showthread.php?p=37606945#post37606945
--------------------------------
Anyway, just some thoughts that might give you some clues/ideas, that may resolve your problem.
Good luck, and I hope you find something that works.
Rgrds,
Ged.
Thanks Ged for the detailed answer.
Unfortunately it seems that my Nexus is not booting complete (not finishing the booting sequence due to corrupted bootloader?) and so I cannot send to it any adb or fastboot command...
I read in the meantime that holding the VOL up button while powering up the Nexus, it will bring it in the APX mode (whatever this mean) and indeed, my computer recognize it as "APX" device.
I hope at least that this is a good sign and a first step to bring my Nexus back to life... but I have no idea what is the APX mode and what can I do in this mode to attempt to save my device...
Do you (or somebody else) have (has) an advice or tutorial for me concerning this?
Regards,
Conrad
Hi Conrad.
I'm in exactly the same situation (I've mistakenly posted a duplicate thread here https://forum.xda-developers.com/nexus-7/general/bricked-tilapia-t4005149). Let's continue here. So:
1. I spent 4 hours trying all possible button press combinations, including VERY long presses. I didn't notice any APX device or Uknown device connected to Windows. I might have missed it, you gave me hope. I will check again.
2. APX mode enables low level access to the chipset via nVidia tool nvflash. You probably came accross these threads here on xda:

https://forum.xda-developers.com/showthread.php?t=2455927
https://forum.xda-developers.com/showthread.php?t=2340237
I haven't so far, as I was not aware of the visibilty of the tablet in Windows. I will check again.
Well, I must have been blind not to have seen all the posts here on xda and everywhere else. I went through the threads and now I know:
1. I can see the tablet in APX mode in Windows. Possibly I could correctly set up the driver.
2. This would be totally useless, since I hadn't backed up necessary blob.
I have a new paperweight
