Lg g2 Boot loops

I am not sure if I can post this solution in this thread as I am not a developer and merely sharing my experience, It seems several people are having issues with bootloops after installing att update or for some other reason, my post deals with helping only a certain issue. You should be able to boot into recovery by any means in order to use my solution.
The problem I had was I was trying to flash a new Rom and copied Rom and gapps into my phone( of course I was rooted and had recovery flashed) and then out of curiosity I wiped everything in advanced wipe in twrp so now I have no Rom to boot into or no file to flash and either download mode would not work, I was p******g in my shorts as I my phone was only a week old and its dead that's what I at least thought. And after spending the whole night no solution was found in xda website and neither did Google help any, now the solution. now u should compare this to ur problem and find where u stand. I installed pdanet on my pc as stock lg drivers don't seem to help pc recognize my phone in recovery mode, then I plugged my phone to pc while phone is still in recovery mode and then opened pdanet in pc and installed lg drivers through it and then adb was able to see my device(until now I was trying adb sideload and it wasn't working) so when adb was able to see my device, I used sideload in twrp and pushed Rom from pc to phone using sideload commands and my phone was back and I am the happiest man in the world. So in short
1. This method works only for people who can boot into twrp recovery but not into phone.
2. Have ur desired roms and gapps ready 3. Make sure u have a working adb in ur pc and if not install minimal adb and fastboot application only onto ur desktop for easy access, and copy ur desired Rom and gapps into that folder and rename them to 1.zip and 2.zip for easy reference and easy adb commands.
4. Download and install pdanet on your pc. Power on ur device into recovery and plug it into your pc. Start adb from the folder u installed on your desktop(hold shift and right click within the folder(minimal adb and fastboot) and click on start command here option, command opens up and it will show in which folder ur in and then type adb devices and if everything is right your phone in sideload mode should show up as adb sideload and if not (this is where the problem is) run pdanet and install lg drivers through it and then unplug exit sideload and restart sideload in ur phone and plug it back to pc and ur pdanet will notify u have connected ur lg phone. Then run adb again and type adb devices and it will show up as adb sideload and now (you should search how to use sideload as I don't remember those commands) and push Rom into (the ones u renamed for easy access and reboot and all should be all. Sorry for the lengthy post but I typed this solution into several posts individually and so decided to put it up as sticky and if anyone feels to remove part of or all the post I have no problem, just wanted to do my help to others with similar problem.

I have more or less the same issue. Was with StockMod for D802 and received an official OTA and accepted and installed it. Now I'm stuck in bootloop. Unlike you, I can go into recovery (CWM not TWRP) BUT I can't seem to go into fastboot mode. When I hold the Volume Up and connect the phone through cable to my laptop, the phone boots but goes automatically into recovery mode. Did system wipe as well (which I shouldn't have) and at that point my phone has no OS to boot into so I used ADB to transfer CM 10.2 and GAPPS to my phone hoping that if I do it like I'm flashing a custom rom will help but unfortunately it didn't. I'm still stuck in bootloop and can't go into fastboot. help please...:crying:

Try a stock Rom and see if it helps.

[SOLVED][HELP] Lg G2 is stuck at cwm recovery

Dear people of xda,
Recenlty ive receive a FOTA update to my device which runs 4.2.2. Being stupid, i did the update although i had cwm recovery installed on my devices. Now my device keeps bootlooping into cwm without being able to do anything.
Ive read tons of threads talking about this issue but i still cant get my to boot normally.
Yingy in this thread http://forum.xda-developers.com/showthread.php?t=2563527 had the same problem but the only diffrence is my pc cant recognize my device in order to do the adb fix by thecubed.
Im plugging my G2 for the first time in this computer and that is why i think my pc is failing to install drivers. I downloaded and instellad latest driver although windows device manger shows error devices not detected and the end of the process.
In order to fix my phone i just need to make me pc recognize my phone in adb although phone was never plugged before to this pc so i think my G2 wont let it access. I tried installing universal driver such as Pdanet as offered in threat but still when i write adb devices in cmd i get device offline!
Download latest adb drviers, lates lg g2 driver, lg user support tool does not recognize plugged device as well. All me sdk manger tools are patched to latest version.
PLEASE ive tried anything possible. spend like 9 hours and still nothing. i would really appriciate your help.
Thanks.
Edit: here my problem with pdanet drivers, it asks me to allow pc usb debbuging as shown in screenshot below but icant do it since im stuck at cwm recovery!

Solved!
BOOM!! after 12 hours i FINALLY manged to solved this problem. Really simple actually lol.
If anyone come across the issue please do the following:
1. Go to clockwork recovery as always, go to install zip from sdcard, choose install zip from sideload.
2. Plug your phone to pc.
3. Run adb with lastest drivers and sdk tools.
4. At the adb folder press shift+right click and start cmd.
5. write adb devices it should show your device id like this (xxxxxxxxx sideload).
6.Download latest twrp recovery from here http://teamw.in/project/twrp2/197 and if you have open europe version G2 like me download latest version from here: http://techerrata.com/browse/twrp2/g2d802
7.put the zip file in the adb folder, do not unzip it.
8. write in cmd console adb sideload xxxx.zip (xxxx is the name of twrp file).
9. cwm will flash twrp recovery over cwm.
10. reboot in recovery in advanced options.
11. now you have twrp recovery.
12. follow this guide : http://forum.xda-developers.com/showthread.php?t=2451696&nocache=1
13. THATS IT!!!
finally after going through this mess, im never using cwm recovery again. twrp is the best
good luck everyone!

X800 Fastboot brick

Hi guys I tried to root my LeTV 1 Pro but it didn't worked.
My phone keeps rebooting in fastboot ( I see the penguin 10-15sec and it reboot again and again) or it stays alight with the penguin.
Computer doesn't recognize it.
Thanks.

Try and plug it to your computer then keep power and wol down pressed for like 15 sec: now fastboot should stick and device shouldn't reboot, so you can flash a recovery (TWRP?) and start over with a new ROM.

Thank you for your reply,
It still doesn't work, penguin stays on screen but it's not recognized by computer ( before the brick it was)
I'm not very experienced in rooting btw.
Edit : The recovery.bat in the file X1_X800_TWRP_Recovery2.8.7.0 says "Complete! The device is ready to reboot into Recovery." which I do but it keeps reboot with the pinguin on.

I recieved my phone today and it just wont stay in fastboot mode. I can do anything I want but it just keeps rebooting before I can flash anything. Any suggestions on how I should keep the Phone in Fastboot mode?

You need to install drivers. After that it will not reboot anymore. That worked for me atleast.

What kind of drivers do I need? Please link them to me I have tried a lot of drivers. The thing is that the phone also does not stay in Fastboot mode when not plugged into the PC.

It's my topic for my problem so don't ask questions for you on it please u_u

I have downloaded drivers (I think) from https://twrp.me/devices/letvle1pro.html where I also get twrp 3.0.2.0
Btw if you are using Windows you can open Device Manager and there you will see your device and what drivers it has installed (you can always use update drivers function, maybe that will help too).
Here is a little guide how I managed to get twrp:
Just download it (drivers and intall them) (and download twrp also). Place twrp file to the folder where you have your adb installed.
In phone settings go to developer menu (first you need to unlock it) and you need to switch on usb debugging.
Connect phone to the pc via usb.
Open command prompt in your adb folder and type Adb devices (if you have drivers installed corectly you will se your devices connected under some code).
Then just write Adb reboot booloader and phone will restart to the recovery.
Type into the comand prompt: fastboot flash recovery name***.img (where the name is the file name of twrp you have downloaded- just a tip: rename it so it is easier to remember for example to twrp. Then the command will look like: fastboot flash recovery twrp.img)
If succesful, write fastboot reboot and that is all.
Btw for me it did not work first time. I had to load twrp for second time and when I wrote fastboot reboot then I immediately pressed volume up so It went directly to twrp recovery.
Hope it helps. Cheers

I have this problem
Hello

Hi guys. I have a problem! My letv x800 CN boots to TWRP but doesn't start the system (EUI logo loading all the time) I don't know how to transfer ROM into the phone in order to flash it. I installed all the drivers and PC recognize it. PLEASE HELP!!!

Sideload issue

Hiya. I managed to unlock bootloader/install twrp and root and went to see if i can put it back to stock.
When i try and sideload the stock firmware, my pc wont recognize adb while it's in sideload mode but it does in normal state.
I also get these errors (see pics)
I have tried installing all the drivers/changed usb ports but now i have no clue what it can be.
Any help please?
Thanks
PS. Using Windows 10

I'm having the exact same issue and I'm also really interested in a solution for this. Also tried uninstalling and reinstalling the drivers and switched USB Ports. The device gets detected without any problems in fastboot mode but as soon as I switch to Sideload Mode in stock recovery, Win 10 shows me this error and doesn't detect my device for sideloading.
Temporarily I could flash TWRP and sideload the zip via TWRP and cmd but I would also like to be able doing it without TWRP again.
Thanks in advance.

Can't anybody help us?

Just download the latest Android Studio software it contains the last ADB driver, i had the same issues after installing reboot, and ADB sideload will work !

Can't copy files to /sdcard/

Hello everyone,
I recently decided too install the LineageOS.
Everything went fine, but I forgot Gapps and didnt want too use my phone without them so I decided too install the ROM again but this time with the apps.
I followed the linageos guide but accidently wiped everything before I could
Code:
adb push filename.zip /sdcard/
(dunno if thats the problem)
Im using TWRP 3.1.1-1. I can get into Recovery Mode. While in fastboot modus my pc detects my phone as an OnePlus, in Recovery modus its just android.
Code:
fastboot devices
shows my serial number. OEM is unlocked.
while in recovery mode
Code:
adb push filename.zip /sdcard/
gets me
Code:
No such file or directory
Code:
adb push C:\User\...filename.zip /sdcard/
gets me
Code:
failed to copy.. remote couldnt create file
while in fastboot mode I get
Code:
no devices/emulator found
Copying by dragging the file into internal storage doesnt work neighter.
I dont know what I did different besides the wipe before the copying. Maybe the wipe deactivates USB Debugging?
Maybe someone sees where my problem is.
Thanks

I guess you don't have an OTG Drive.
you could always go 100% stock again and then flash LineageOS
http://downloads.oneplus.net/oneplus-5/oneplus_5_oxygenos_4.5.13/

well first thanks for your reply. I flashed the original recovery and tried 2 sideload now. Seems to be driver problems. So I have to try every solution with Win10 and OP5 drivers I guess?

Make sure the Android drivers on your computer are up to date and also that you don't have any old drivers from a previous phone. I accidentally wiped everything on my OP5 once but when I connected it to my Windows 10 computer the OP5 was still recognized as a storage device--but I used TWRP not the stock recovery and also used the file explorer in TWRP. With the stock recovery you should still be able to side load flash the stock ROM from your computer. If you can't it's likely a driver issue.

I had once a similar issue, although not exactly this, just something with drivers.
A long process to fix was to install Linux as a virtual machine in Windows and that worked well. I could do all I needed, the phone was quickly recognized.
Virtualbox or VMware both are free/have a free version and I used Ubuntu.
Give it a try if all else fails.
