Hello, I decided to go back to the stock rom on my Optimus 4X HD. I did so by following this guide by Demetris: http://forum.xda-developers.com/optimus-4x-hd/general/lg-p880-firmware-flash-upgrade-t2919195
I flashed V20B kdz in upgrade mode through the LGflashtool and everything worked fine. When rebooting I can hear the bootup sound and see the logo but it stays in a bootloop. The thread I linked above suggests that I do a factory reset.
I can access the stock recovery but it's not working properly. When I press factory reset I see the android guy with an Error! icon above him and nothing happens.
adb sideload fails everytime but I can use adb shell and access the phones storage that way.
Bootloader is unlocked. Another thing to mention is that on the back of the battery it says not for "resale". It might be a developer preview phone because I bought on display for half the price in a phone store.
How can I recover from this bootloop? Any help ?
I'm new to the development side of Android and I bought a ROOTED phone from a Co-worker. Well my phone tried to do a software update and the phone is stuck in a CWM boot loop. Me not being familiar with CWM or ROOT, I pressed the factory reset button in CWM. Now I am unable to fix it. I have tried ADB sideload to load ROMS to the phone. They will say they are installed but then it will just go right back to CWM. I am trying the LG flash tool now but my phone will not go into download mode. Can anyone help me, please. I love this phone....

Can you get into clockwork mod without it looping
If not try command
Adb reboot recovery
Chances are previous owner has some Roms saved on the SD card
In the download folder
Keep in mind Roms are carrier specific on this phone
Yes it boots into CWM recovery and I accidentally wiped everything. I am trying to use the LG flash tool but it will not even go to download mode....
In recovery factory reset clear your cache and dalvic
And try sideload again,if it doesn't work try pushing the file with adb
If you can't get that pm me and I'll troubleshoot with you.
D950 on LG logo
I have a D950 only boots to the LG logo. I rooted the phone and then tried to install CWM. I didn't know about Freedom Flex then, so i used a forum post to try and do it. I successfully got CWM on the phone, but now it won't boot past the LG logo (also boots to CWM, I think it'll go into download mode). I'm not sure if I did any of it correctly, but I've tried CWM, ADB, LG Flash Tool, Odin, etc to somehow get the phone working again to no avail. I'm not even sure if anything can connect/detect the phone. If there's nothing I can do then fine, but if anyone can help/try to help please do. It was a nice phone an i'd love to have it working again, its been so long.
Hello,
I tried to unlock my bootloader, but I made a mistake and I flashed the 10b instead of the 20a on my D405n, I flashed TWRP with Flashify and then I rebooted my phone. But I had no recovery and a black screen.
Then, I saw a guide (http://androidforums.com/threads/gu...oad-mode-no-recovery-mode-no-fastboot.893311/) and I did what they said. But I don't know why, it still doesn't work and in addition, my computer doesn't recognize my phone at all.
A precision: when I plug my phone without battery, I can see the logo "Where's the battery on my phone"
Can you help me please ?
Thanks in advance
Hey guys as the title States I have my old d950 g flex that I ended up selling to a friend. The phone was rooted on the stock ROM, well all was good when I sold him the phone but being is a unlocked at&t phone when we got it did automatic ota updates which at that point bricked the phone. So now at this point the phone only boots to custom twrp recovery . shows the LG logo then goes straight to twrp every time. I've tried wiping the data, DAV cache, etc still to no avail to fix the boot. Now I've tried to get it into download mode so that I can flash it back to stock but the phone will not enter download mode. Every time it still goes to twrp. Is there a way to force it to Download mode so i can flash back to stock using rhe flash tool. And or even a way just to flash back to stock without the flash tool and download mode ? I've been searching and trying to get to work for days to no avail. So if you guys could help I'd greatly appreciate at the point were I'm about to just throw the phone in a fire and then have to give my friend his money so I'd really not want to do that lol so please help if you can. Thanks in advance
Update:*** So after searching the internet for days finally found out this fix for bootloop (recovery or normal bootloop) because of the phone being stuck in twrp recovery upon boot it would not let me go into download mode. I did this fix.." http://forum.xda-developers.com/lg-g3/development/fix-stuck-custom-recovery-trying-ota-t2907508 "and phone immediately booted as normal then was able to flash back to stock using flash tool as ive been trying to do for days now so if anyone has bootloop issues forward to this thread
Hi all,
I have put myself in horrible situation look like phone is bricked . I can not start my phone in recovery or download mode even.
here are the series of step I had performed:
1)Unlock bootloader and intalled latest twrp-3.0.2-1-h815.img 16.5M 2016-09-15 07:23:54 EDT for ( since 815/811) has same twrp on twrp website.
2) tried to install lineage OS rom for 811 but the recovery gave me problem that device is 815. Please install 815 rom, so I flashed 815 and it flashed fine and device booted and worked fine.
3)Now the problem starts, it crashed after some time and stuck in boot loop.
4)I had tried to boot in recovery and tried to restore back up image, but it crashed in the middle and after that I was not able to start to recovery.
5) Then I used the LG UP and flash kdz file H811V20r_00_0111.kdz for stock rom.
6) It flashed successfully, but device never got boot up and now I am unable to go to download mode.
7) Displaying small download mode symbol but device is stuck on the symbol and not going to Download mode.
I am stuck now, Is there any solution to come out of it. Please help me.
Thanks
Now my phone starts into download mode, and I flashed the original kdz h81120v_00_0425 using download mode, after flashing first time, it went to opitmizing Apps screen but restated in middle.
After that I tried multiple times sing hard reset, but it always freeze on 2nd screen when I press yes to reset.
I flashed kdz multiple time using LG up, but it stuck on LG logo with unlocked boot loader msg. not going to the bootloop.
Current condition is now I am unable to enter download mode it respond but freeze before entering download.
I can not hard reset as it always freezes on 2nd hard reset screen and not formatting.
No charging.
I am not sure, If this is some hardware issue or emmc fault , Please help me on this..

I know I have done few things wrong in confusion, but realized later on. It is H811 TMO model for sure.
I did select refurbished while using LG UP
My phone is not completely dead.
Pressing power button it stuck on LG logo with unlocked boot loader msg. not going to the bootloop.
I am unable to enter download mode, it responds but freeze before entering download showing 4 blue dots.
I am able to enter recovery but I can not hard reset as it always freezes on 2nd hard reset screen and not formatting.
No charging, Device Manager shows nothing.
Is there a way to recover??
