Stuck in TWRP Loop - G2 Q&A, Help & Troubleshooting

Can't get the phone to boot on anything other than twrp. I reboot, it goes back to it, I do a recovery, it goes back to it. I can not get my phone to turn on and get past this.

Did you try this?
http://forum.xda-developers.com/showthread.php?t=2451696

Yes, and that put me in an LG Screen bootloop. I can access adb on my pc but when I try to use the code:
dd if=/dev/block/platform/msm_sdcc.1/by-name/fota of=/sdcard/fota-backup.img
I get: 'dd' is not recognized as an internal or external command, operable program or batch file.

Hi , I've tried the method without adb, after I run the command I get a "no space left on device, 65537+0 records in,65536+0 records out, 32 mb copied."I have about 15gb of internal storage available. I'm new to adb pushing, how do I get my pc to recognize my phone while in twrp? I have the correct drivers installed. Btw I'm on Tmo, flashed the recovery img thru flashify, now stuck in twrp loop. When I go to download mode it automatically shows a screen saying firmware update,don't unplug usb. And on bottom left it says rooted. tried doing a factory reset in twrp, took about 7 min, completed, rebooted, still in twrp loop. would doing an advanced wipe or formatting data help?

The last thing I saw in twrp was a screen asking me to reboot and telling me that I am no longer rooted. I don't even know how this is possible.

I would put your phone in download mode and use the LG Mobile support tool to do a recovery on it.

Thank you all for the help so far. I feel I am making progress to restoring the phone but I have been "installing drivers" for a long time now with them never completing so I am just waiting on that before using all those tools.

i tryed the drivers still nothing my computer is litterly not reading the phone at all
Same issue here. My pocket got warm earlier and i pulled out my phone and it was in CWM. Rebooting only brought it back to CWM. Phone is not recognized by PC (with correct drivers) and I can't get into download mode at all. Was able to flash TWRP through CWM because i had a zip of it on the phone. But even with TWRP, every reboot to... option just takes me back to recovery.
Install pdanet, while phone is connected in recovery mode to pc open pdanet and install lg drivers through it and then open adb in ur pc and type adb devices and if it sees then open sideload in twrp or cwm and push Rom to phone.

[Q] D802 Bricked, computer won't recognize it

Hi,
I recently updated to the official 4.4.2 kitkat update.I then proceeded to root the phone, and then stupidly, installed CWM. I rebooted, and was greeted with an endless LG Splash screen. Now, I tried a HEAP of ways to restore to stock, all of them returning the same problem, my computer won't pick up my phone. In download mode, nothing happens, nothing in device manager, and same when I'm stuck on the LG splash screen. When I go into CWM, it then recogizes my phone, but the methods of restoring to stock won't work with CWM running in the background. CWM also won't let me mount the usb...
The methods return the same error: Phone not detected, please plug the USB cable and retry.
Ubuntu won't recognize the phone in all three modes, and another computer does the same thing. (Both Windows 8)
Methods of stock restoration tried:
-KDZ
-LGMobile support tool
-Ubuntu (This: http://forum.xda-developers.com/showthread.php?t=2582142)
Can anyone help?

Yes, it does work now. I was able to restore to stock by adb pushing phillz recovery, and then flashing that, then adb pushing the stock ROM. Everything works as it should, now.

Does it recognize your phone when it's in the custom recovery? That was the only way I could do it on my phone.
Good luck!
I tried ADB devices nothing came out.
I have the same problem as listed in this thread. Tried everything to SHort circuit the chip. Basically everything.
I think the last thing i haven't try is dump it into the bin.

Only one question,
Do you have any ROM installed currently or stuck without any rom. Like boot loop and secure boot issue etc.
If you have TWRP at least installed on your device, you may use "adb push xxxx.zip /sdcard/xxxx.zip" command if the device is discoverable in "adb discover" command. You may follow the guide here "http://www.droidviews.com/android-4-4-2-kitkat-rom-on-lg-g2-d802-install-twrp/"
If you are able to boot in X rom you may use this guide to shine yourself in stock rom

Firstly you may not go do download mode for flashing factory rom. You can do the same even from recovery. However, the guide in http://forum.xda-developers.com/showthread.php?p=51693321#post51693321 seems working for many. You may give that a try.

You need flash required partitions (like aboot and laf) to boot phone to download mod. Then, you can install stock ROM from LG Mobile Support Tool.

Big problem with my htc U Ultra :(

Hello, I've a problem with my htc U Ultra (ocedugl). In fact, I upgraded supersu and when the phone was supposed to restart, I was stuck at the htc logo. I then had a backup of the boot and the system in reserve on my SD card, but when I wanted to restore them, I had the error 255. Only during the restoration of the system.
I do not know what to do, this phone is a real mystery to me. I have an internship tomorrow, not very practical suddenly. :/
The most problematic in all this is that twrp asks me for a password to decrypt the data at startup and I have the impression that I have only worsened the case. If anyone could help me quickly enough please.
PS: Me who I usually do alone, I must admit that I dry.
PS 2: I installed root switch for snapchat just before too, I do not know if that affects.

Turn off your phone. Press Power and volume down at the same time to boot in to download mode. connect to PC and flash TWRP
Install via ADB
Open the folder where your TWRP Recovery .img file is saved.
Then open a CMD window inside that folder. To do that, Shift + Right click on any empty white space inside the folder and then select Open command window here.
Connect your Android device to the PC. Type the following into the command window to boot your device into bootloader/fastboot mode:
Once your device boots into download mode, type this into the command line.
fastboot flash recovery twrp-3.2.1-1.img
Once TWRP is successfully flashed on your device, you can use TWRP now

HTC u ultra Oreo messed up my phone and now I need help.
My story:
Bought a HTC U Ultra European.
I was kind of satisfied with it. The device didn't really live up to my expectations. But when it was upgraded to Oreo the screen start to flash when opening apps and Bluetooth sound went bad. It looks like the app opens twice. After a while it went even worse with the flashing.
Anyways I unlocked the bootloader and flashed TWRP 3.2. That process went fine then I wanted to flash leedroid to test something else (yes I saved a recovery file).
The result is now my device is working but I'm unable to flash twrp again. Since Oreo still sucks to u ultra and I want to downgrade to nougat since it works.
My adb (Linux) detects my device but when I start my HTC in download mode I'm unable to flash to since my PC says:
<waiting for device>
When I try to start it in recovery mode it sticks in a reboot loop.
And BTW I can't restore factory settings.
So if anyone can give me any answers it would be great.

I already installed drivers and tried other cables. Did the procedure again bit with no results.
I think the big problem actually is that since the phone can't boot into recovery mode it get messed up.
I try to do a hard reset but every time I either get stuck in a bootloop or the phone boots into regular mode. So I literally can't do anything to fix this problem as far as I know.
Getting a little bit of frustrated over here.

Because I can't boot to recovery mode. Either I get stuck in a boot loop or the device boots just like I rebooted it. So I can't get to twrp and I can't flash anything. I can't hard reset either. All I can do is reboot, enter bootloader and enter download mode.
So I guess I'm stuck with Oreo that's a mess on my device.
