AT&T LG v20 (H910) boots to AT&T logo and hangs - LG V20 Questions & Answers

Hello Anyone,
I have the LG v20 rooted for some time now with Android N and working good.
Two days ago, I removed some apps with titanium backup and i think one of them was a facebook installer apk, one was the visual voicemail apk and the other was something like tether provision apk. Then I placed the phone on a charge for a bit.
When I came back to the phone, it seemed to have rebooted but was stuck on the AT&T logo after the LG Logo. I did a battery pull and same thing. I removed the sim card, same thing happened. Since it was hot, I let it cool and then tried again, no difference.
I backed up the partitions and then did a wipe and reinstalled the rom, it works taking me to the homescreen. I then tried to reinstall the backup and it goes back to the AT&T logo and hangs.
Is there any way to figure out what file I deleted that is causing the hang and how to put it back with TWRP so I can start booting the phone properly again?
Thanks.

If you're rooted and have access to twrp just dirty flash your rom

No it won't just wipe system, davlik, and cache also don't forget to flash supersu or magisk right after you flash the rom before you boot to system

ok, thanks. I ran into some trouble when i did that where my phone was asking for the passcode and eveytime i entered it, it came back as the wrong code. Then my phone rebooted into TWRP after the 10th attempt and then got stuck in a TWRP boot loop.
I got out of the twrp boot loop and reflashed the rom, then restored only my data file since my system file backup was not booting (original problem)
In case anyone else has this issue, if you have the TWRP recovery and your phone does a reboot into the recovery for factory reset, your phone will only reboot into TWRP unless you do a battery pull (or force shutdown) and then manually boot the phone into TWRP, then reboot into the system.

[Q] Unmodified Nexus 4- boot loop?

Hi,
I am writing this on behalf of my mother's phone. She has a completely stock Nexus 4 on Net10.
This phone hasn't been touched by a computer. Any development settings are also disabled.
I came home from work and my mom showed me that her phone wouldn't boot. It was boot looping on the "X" boot animation.
So I went ahead and accessed the boot menu and selected recovery and did a cache wipe. No help. I let the phone run out of battery and charged it back up, no help.
I have no clue what happened. The phone was working fine previously. Again, the phone has NOT been unlocked, rooted, etc. Completely stock Nexus 4.
I would like to fix her phone but I would also like to keep her data intact. She even told me it is very important to "keep everything on the phone".
Any assistance would be great.

Try the following:
- wipe cache and dalvik cache
- Flash a custom kernel
- See if boots
- Make a complete UROOTED backup and save it in the computer
- Flash factory image and relock bootloader
- Restore backup
Tell us if worked
By flashing a custom kernel it is required to unlock the bootloader which will wipe the entire phone.
Your only hope is to use stock recovery to install a signed OTA package (if it's on 4.3 wait for 4.4 ota package).

[Q] Hard Bricked Verizon LG G2

Alright, my friend has a Verizon LG G2 and i helped him install Malladus 2.0.1. He was previously on Malladus v1.2.5, and he followed this guide here: https://docs.google.com/document/d/1xsU9W656TA-Lw1LAlL7hqROf2QjiOI2puyDU-DDP41Q/edit and everything went okay. When he tried to restore his apps via Titanium Backup by trying to restore the apps from the nandroid, the apps didn't show up. In the guide, it said if you need to go back to android 4.2.2, you need to flash the 12B radio, so he flashed the 12B radio and restored his backup of Malladus 1.2.5. After rebooting into system, he got stuck in a boot loop, so he tried to get back into recovery, but wasn't able to because it wouldn't turn off. Also, he could not get adb access and now his device doesn't respond at all when clicking any buttons or plugging it into the charger/computer. Any ideas?
edit: charger doesn't charge the device

Has he tried removing the battery?

Unfortunately, you can't remove the battery on the lg g2, but he left the phone plugged in over night and he is now able to get into download mode
edit:he got into recovery, so i think we're good now

[Q] !HELP PLEASE! I think I bricked/boot loop my LG G2

Ok, so when I got my LG G2 the first thing that I noticed was the notification drop down menu and I really didn't like it as I prefer the stock android one much more. So I decided that i was going to root it, install TWRP and then install CM12. None of these went too well but defiantly the last one went the worst. I used the one click LG root application for pc to root it, I was a bit scared of this but it went alright. Then I tried to install a custom recovery and figured that I would use rom manager to install CWM recovery but for some reason after that it just booted into stock android recovery. After getting annoyed by this I looked for another app and settled for AutoRec to install TWRP and it worked fine. I booted into it all ok and I was happy. So I charged it up to 90% as some people say you need at least 80% to install a rom. I downloaded the latest CM12 nightly from their website and then the Google apps and saved them into a folder I named cm12files. I booted into recovery and did a ?Nandroid? backup (I think) and saved those files to both my phone and now onto my laptop. I wiped Dalvik Cache, System, Data and Cache. Then clicked install and selected my cm12 download. Then it came up with 'e:error executing updater binary in zip' and said that the install Failed. I googled the error and some post said that I should reboot it or something and as the retard I am I did that and as I have wiped it there is no android so it just showed this (tinyurl link: o2sylpp (if you dont want to click it it is just the lg boot logo)) then this (tinyurl link: nsduxck (if you dont want to click it it is just the lg logo with a message saying security error)) and keeps doing it over and over again (they are not pictures of my phone but they are exactly what my phone shows. Is there anything that I could do? I don't really mind if I get the LG android back.
Answer
Oh I fixed it. When I plug the phone in and then unplug it, the phone turns off and when it was off I held down the volume down and power until the lg logo popped up. I then just for half a second let go and pressed them both down again, a reset screen should come up but it didn't work so I just selected NO and it booted me into TWRP. From here I selected restore, chose by nandroid backup and it all worked!!!

Nexus 6P stopped booting, nothing I do is now working. PLEASE HELP ME.

At this point I have completely run out of options. I AM CALLING UPON THE XDA COMMUNITY TO PLEASE HELP ME. Little bit of background info, nexus 6p was rooted and modified through xposed. Had some modules installed, mostly quality of life and visual/theme modules, as well as the latest version of SuperSU.
These past few days my Nexus 6P has completely stopped responding at times. Extremely laggy and could not do **** with it, systemui kept restarting over and over and over again for no reason. Had to keep force rebooting (holding down the power button for 10 seconds) multiple times over and over again, to the point where it suddenly stopped booting into the OS, it just kept giving me the boot animation loop, i could only access the TWRP recovery i had installed. Before all of this **** went down, I had created a TWRP backup because it would be my safety net if i could somehow miraculously get it to work. Now i have a backup of my TWRP BACKUP FILE on my desktop.
I have wiped caches more times than i can count, have tried factory restoring and formatted the data, and tried flashing the stock google image (the same one that i originally flashed at the time that I got the phone when i started to root) as well as flashed the old TWRP version i had, as well as the current latest version of TWRP, and then transferred the backup i made back onto the phone's internal storage. Tried restoring the old backup from TWRP, and each time it restores, it just reboots without reaching 100% and once it reboots, it still gives me a bootloop, this time, no boot animation, it just gets stuck at the Google text with a little "unlocked" logo at the bottom. I have completely run out of options, and have A LOT of EXTREMELY IMPORTANT information i have saved on the phone.
I will say it again. I am EXTREMELY DESPERATE to get my data back, to the point where i am even willing to offer a cash reward for any help to get my phone working back to the way it used to, or even at least to extract the information through the backup, if at all possible.
Additional information about the files and images I used:
angler-mdb08k is the name of the google image i had back when i had the phone and have flashed again
twrp-2.8.7.2-angler is the TWRP version i had back when i had the phone originally at the time
I had flashed and followed guides online through adb method.

SystemUi constantly restart

Hi, I've been using this phone for last 2 weeks and ive experience this SystemUi constantly restart by itself. No error or crash popup, just the mobile data goes to error sign -> no sim card -> mobile data. Sometimes rebooting the device does help but most of time it does not.
Ive excounter this problem either unroot or root.
Have anyone experience this issue too?
OnePlus 6t, 8gb, Matte Black, International Ver
Stock OOS, Stock Kernel
Yeah I've noticed something like that. It's frozen up for a few seconds. Screen touches become unresponsive. Last time it happened I was just going back pages on Amazon app and it froze. Unrooted T-Mobile latest update. Maybe that's why they have a on/off schedule in settings.

I had the same issue. I tried to recover by restarting. Now i am stuck in boot loop and constantly rebooting. Please help here.
This isuue happened to me since upgraded to OB1. My phone was rebooting randomly after booted for just a few minutes. I have tried get rid of all Magisk modules, dirty flash rom, reflash twrp and magisk. Etc ... After that I can't access the phone anymore. The phone just kept on shutting down after logged in. So i tried to get it recoverd by twrp but sadly, twrp didnt show the login screen so the data was encrypted including my backup recoveries.
I ended up fixing by rebranding with stock ota fastboot.
I think you should first backing up your data to external storage if you still have access to twrp. And just do whatever needs after that.
Don't be dumb like me and Good luck.
