Hi guys,
I had posted a brief thread a couple weeks ago stating that my Nexus 4 restarted by itself, and got stuck in the bootloader animation loop. I couldn't remember whether I had enabled USB debugging in my phone prior to it killing itself (not rooted, completely stock, did the OTA 4.4.3 update just a few days before my phone died, and phone's been out of warranty for quite a while now ).
So I installed the SDK developer tooklit, and followed instructions to set up ADB.
However, everytime I boot my nexus 4 into recovery mode/"safe" mode, I get the following screen ("Screenshot 1" below).
From there, when I boot into recovery mode, I get the following screen ("Screenshot 2").
Every time I connected my phone to my laptop (keep in mind that I cannot start it .. I always plug it in when I'm in "Screenshot 1" mode) and try to used "adb devices", I get the following cmd screen ("CMD ADB Devices" picture below). I've repeated this process and tried plugging the nexus in during various points in different "safe mode" options. Same result: nothing is detected.
So I got frustrated at trying to backup any data from my phone, and just chose the "wipe data/factory reset" option from the nexus recovery mode, and I got this screen ("Screenshot 3"). I've tried this several times, and I keep getting this screen.
So my nexus committed suicide, and I'm totally not sure what to do. I've been trying to learn how to use ADB etc for the past couple of days by scouring through the xda nexus 4 forums, but I'm still very much a n00b. Do you guys have any advice as to what I can do to get my nexus 4 back to a usable state again?
Things I've already tried (in order):
http://forum.xda-developers.com/nexus-4/general/how-to-how-to-flash-factory-image-t2010312
http://forum.xda-developers.com/galaxy-nexus/general/guide-phone-backup-unlock-root-t1420351
I also tried to ADB sideload a stock Nexus 4.4.3 factory image, but it is useless since my device won't even show up in CMD when i enter ADB devices.
However, the problem is that my nexus is never detected in CMD no matter what combination of things I tried, so I can't even do half of the things both of those thread instructions state.
I would greatly appreciate ANY ways to factory reset or flash working firmware on my phone! :highfive:
Edit: I reinstalled Android SDK, and connected my nexus to my laptop after entering fastboot ("safe" mode; volume down + power from phone off state), and I was able to get a slightly better looking CMD window when running ADB Devices command (See "CMD ADB Devices 2" picture). However, same problem as before, where my phone isn't even registering via ADB.
So again, your input would be tremendously appreciated.
If you boot in the bootloader (Volume- and Power) it's normal that you can't use adb. You have to use fastboot in the bootloader.
What is the output of fastboot devices?
Code:
fastboot devices
Have you already tried to flash the factory image or did this fail, too? You have to download the factory image from google, extract it and connect the phone in the bootloader/fastboot mode. Run the flash-all.bat then and it will reflash the stock rom. This will wipe your data, but I guess this shouldn't be a problem for you anymore because you already tried to do a factory reset!
If this worked, boot your phone and if it works fine, I would recommend to relock the bootloader (because it gets unlocked automatically if you flash the factory image and if you don't want to root/modify your phone in any way, your bootloader is usually locked):
Code:
fastboot oem lock
Try it and if there are any other problems or if it doesn't work, just ask again
Hi,
yesterday I got d802 phone to fix it. First the phone was stuck at LG screen with certification error which I fixed. Phone was recognized by PC and i installed twrp on phone. I tried everything (i guess) and now phone is stuck at LG screen and it doesnt move. Now i cannot go back to twrp recovery but i can get to download mode but phone isn't recognized by pc so i cannot flash kdz file to phone. I'm really stuck at this point. Is this real hard brick or is there any way to fix it? Any ideas what should i do or something i can try?
I tried to plug phone in other computers and it's the same thing. My laptop recognized that something is plugged in once but it didn't know what was it so by now. Somehow from time to time phone doesn't go to download mode but it goes in hardware key control mode.
Hope someone can help...
So far i manged to get to recovery mode but adb sideload isn't working. I tried to wipe everything and that didn't help. As we speak factory reset is in progress but I think it's stuck on formatting cache. I hope I'll be able to get the phone recognized in download mode. Any suggestions are appreciated
I have made some progress. ADB is working now and i pushed cyanogenmod and on installation it says that it cannot mount data and cache. I think that main problem is that phone isn't rooted and now I'm trying to root phone via adb. If someone knows anyway to do this that would be great
I recently bought a LG G2 for a great price, when I got it back to my home and turned it on, I discovered something. I found that it wouldn't boot and Download Mode is REALLY BROKEN. I can still get into TWRP, but the UI is in ruins and I can't navigate. When I try to enter Download mode, I get used to get an error code. Something like: error: cannot verify download mode, or something like that and when I try for a normal boot, I just get stuck at pixelated display. Really what to get this phone working, I can't disassemble the phone and I don't have the tools nor money to get said tools. When I power it on, I get an extremely pixelated display and I don't see the LG logo anywhere when I boot it up. I have been able to get the logo to appear once or twice. There is no warranty on this phone, can't afford to send it back to LG. I am getting very stress out over this device.
Things/Methods I have tried:
1) I tried to enter Download Mode, but it 'crashed' per se, and it then proceeds to wreck my PC, by flooding my display with Windows Explorer pop-ups.
2) Tried a normal boot after I restored my previous ROM before this stuff began, and it did no good.
3) Tried to get into fastboot, but apparently, it doesn't seem to exist on it, so I can't use other methods.
4) I downloaded the appropriate KDZ file for my phone to try and flash it back to stock, but the LG Flash Tool didn't recognize my device. I attempted to try and use the Minimal ADB and Fastboot tool, but it didn't to anything for my phone. Everytime I entered a command, it's say "<Waiting for Device>" and then it'd proceed to freeze there not do ANYTHING.
5) Tried a normal boot and that did nothing.
6)Tried using the ADB Sideload feature in TWRP, but that proceeded to crash the UI even more and then the device would freeze.
7) Wiped the Dalvik, System, Data, and Cache and then attempted to restore the OS, but then when I tried to get it into the the OS, it'd just boot loop at the pixelated 'boot screen', if that's what you'd call it.
8) Tried to get into fastboot, through Minimal ADB and Fastboot, but nothing happened.
9) Tired to fix Download Mode, but then the error arrives and then the device proceeds to a completely black screen.
10) Contemplated on physically removing the G2 from this plane of terrestrial existence.
I would appreciate the help. I want to get this phone back to Stock Firmware and then use it as my primary device and sell my Moto G.

First verify model number of the phone viz D802/ D803/ 802T. Download original firmware file and Flash appropriate bootstack, download bootstack from https://github.com/lg-devs/bootstacks here.
After flashing boot stack, connect phone with cable to PC.
Use key combination (depending upot the bootstack you choose) to boot into download mode.
Use LG Flash tool to flash original firmware file.
You are good to go!

Download your recovery for your model, try flashing in TWRP if you can, then flash correct ROM for your device *Link*http://www.gregtwallace.com/lgg2-projects/twrp/?version=2.8.7.3
first thing you should do is to know if phone was refurbished, some phone claim to be d802 and they are not..
you do this by opening phone and checking MOTHERBOARD model or variant.

I opened up the phone, to an extent, and it is in fact the model I thought it was. D801

I don't understand how I can flash the boot stack when I cannot connect my G2 to my PC and it work. When I put it into 'Download Mode' I get an error and it crashes, then a bunch of unformatted drives appear and I can't use a flash tool, because my PC doesn't detect that it is connected to the computer.

I can't get anything into the TWRP recovery, I am able to get into TWRP. Outside of that, I can't do much. I can restore my back up, but both of them were post-crash and I can't do anything. I tried the ADB sideload, but it wouldn't launch the file. I enabled MTP (Media Transfer Protocol?) but I didn't see my device.

Update: My sibling, when they came over, smashed the screen out of it, so I can't do anything with it until I get the screen replaced.
Hi,
I'm opening a thread because I just couldn't find any way to unbrick my device. In the past I used the FlashTool2014 to go back to the stock LP KDZ for my device.
I was in the stock rom when I decided to mess with the build.prop and then went back to the stock backup. When I restarted the phone it showed the LG logo, screen went black and never booted android. I could access the stock recovery but the Factory Reset won't work.
Then I decided to go to download mode, it connects and the PC detects it as an MTP device. I open the FlashTool2014 and it detects the device OK. When the LGUserCSTool opens it says the Upgrade stopped due to an error and the device stays on 0% and shows USER B70 in the console. I can press Retry, turn off the phone and reconnect in Download mode but the LGCSTool just wont push the firmware.
I suspected I had a driver issue so I tried using a clean win8 install I have for this purposes without success. I cant flash with the TOT method since the other LG Flash Tool wont detect the device in download mode when connected to the pc. This is really weird.
Any ideas ?
Thanks in advance.
EDIT: Solved with another tot file (almost lost all hope), took me 20+ hours to download it, I'll better make a backup of this files on the cloud. Still having problems with STOCK firmwares but could install TWRP and get CM13 which doesn't give any problems.

enjoy:good:
The phone went into bootloop randomly, it loops at the cyanogen intro and sometimes after the android is optimizing message. I can go into recovery(cyanogen), it has no option to connect to a pc or anything similar. It shows option to enter bootloader, install update from storage etc. I want to recover the images, videos from the device and don't care if i'm unable to use the device after recovering it. Couldn't install twrp as the device doesn't show up in fastboot devices, i'm guessing this is due to usb debugging and such other options not turned on. But i can't do these now as the device is stuck in a bootloop. Is it possible to recover the data or all i can do is flash rom using qfil and lose my data??

Hello, seems your bootloader isn't unlocked and you have the stock recovery, no custom recovery like twrp. So your device cannot be recognized by adb when you have it not enabled.
Try to shut it off by pressing the power button for some time and try to charge it full, then switch on. Also clearing cache in stock recovery can help.
