Random Reboots After a TWRP Backup - G2 Q&A, Help & Troubleshooting

My phone was running fine, all OK yesterday until I decided to do a backup in TWRP and then reboot. I like to have a recent backup just in case anything happens and since I was considering updating to 4.4 I made one. I've done backups before on this version of TWRP 2.6.3.4 without any problems and I also didn't flashed anything new.
The thing is that after I made the backup and rebooted my phone something got messed up and now the phone randomly reboots no matter what I do. I tried a clean install of the ROM (wiping cache, dalvik, system and data), restoring the backup I had just made, changing kernels, fixing perms and basically all I'm allowed to do from TWRP but none of that has stopped the random reboots.
It just boots, doesn't recognizes the SIM and after a minute or so it loops back to the LG logo. Some of the features of the phone are not working either and during this annoying process of booting and then looping back it is running very hot and draining a lot of battery.
My phone was running 100% before I made the TWRP backup which I've done many times before so I'm pretty sure that's not the problem. Right now I have no clue of what is causing this so any help would be very appreciated. Thanks in advance to anyone willing to help :good:

Got stuck in an endless reboot on a non journaled rom.. No problem!

I tried restoring the stock battery icon using ACS 1.1 and my phone got stuck in an endless reboot cycle. I kind of started freaking out as my phone had been acting flawlessly prior to this and I was scared of corrupting my data. I had a recent restore point saved (I have MyBackup make one every morning while I'm sleeping) but that would mean I'd have to wipe my phone and after everyone complaining about how hard it is for them getting ACS 1.1 to work on there phone I was scared to test my luck a second time. I thought the only other option would be a battery pull which would lead to bad data with bad backups. So instead of following one of those two options I three finger rebooted out of the loop and immediately three finger booted into CWM. I wiped only my cache and dalvik and then reflashed 1.1 over the existing one. I then rebooted and the only things I had to do were reflash my Vision kernel and delete a few apps that I did not want that come with the ACS rom that got reinstalled. I assume none of my data got corrupted and I know this probably won't save everybody from corrupted data due to endless reboots but just thought I'd share my method. So far everything has been running just as good as ever.

[Q] Phone bricked after battery replacement.

The last few days I had an experience that I want to share. Maybe it helps somebody else.
Last week I upgraded my Defy from Quarx's CM10.2 to CM11 version 20140724.
It ran for about two days. It was stable and the performance looked better than before.
Then, when I was outside, my battery was empty. I always have another battery with me, so I exchanged the battery.
Then, two seconds after I inserted the battery, a black screen with the following white text appeared spontaneously, without pressing a button:
Bootloader
09.10
Code Corrupt
Ready to Program
connect USB
I could not enter recovery, or anything else.
So, I decided to go back and flash the original Motorola Android 2.2 version.
On earlier occasions this worked perfectly when I bricked my phone, but this time, after flashing the SBF with RSDlite, the phone hang while booting with the android logo on the screen. Only after a few hours of trying different SBF systems, the idea popped up, that the problem was not in the SBF, but in the combination of the old Motorola system and the new CM11 data partition. So, I entered recovery and wiped the data partition.
Then the system booted normally and I could proceed with rooting the system, installing custom recovery and restoring the backup.
Everything is back to normal again.
Now, I wonder what could have caused this problem.
I am a bit suspicious about the backup method I used. I create backups with the online nandroid app. The CM11 system installed the TWRP 2.7 recovery. The first time I tried to restore a backup, I noticed that the TWRP recovery had a problem with the old (CM10) and the new (CM11) backups, because they contained files for partitions and-sec and recovery, that it could not handle. In later attempts to restore the backup I unticked these partitions and the restore seemed to work well. I rebooted it several times. Could it be that these attempts damaged the system in such a way, that only when inserting a battery, the corruption was detected?
Or should I assume that there was a hardware glitch when the battery was replaced?

iirc this was one of the bugs of cm11. if you let the battery runs completely down, it may not boot again. not sure if this has been fixed with the latest cm11.

[Q] Failed recovery of nandroid backup - why???

Hi all,
Some time ago i asked, and received, some support on these forums on how to properly carry out a nandroid backup... following the sound advice i got, i carried out my backup (using TWRP for the record, with all the options checked), and stored it away for a rainy day... said day came yesterday, when i messed up my system and rendered it instable (i tried to manually delete the dalvik cache directory in order to free up the 2,5GB of space it was taking)... since i knew there was i high chance of this ending in disaster, the last thing i did before the delete was carry out another nandroid, so i could easily return to where i had left off... how wrong i turned out to be
as soon as i the system became instable following my experiment of deleting the d. cache directory, i recovered the latest nandroid (i.e. the one i had made just hours before) and everything seemd to go smoothely until the first reboot... when the following happened:
- first reboot after recovery took ages, much like the first reboot following the flashing of a new rom... not the end of the world, but that was the first sign that all was not well
- the status bar disappeared, and there was no way of making it come back (i.e. nothing to do with the launcher, i typically use apex but i i tried switching to both nova and touchwiz which i also kept up to date but the stats bar was nowhere to be seen)
- even if not having a status bar with all the info on it is acceptable (which of course it isn't, but lets just say), the sytem became completely instable after 5minutes of operation... with each app taking turns to shutting down until i kept getting the message "system UI has closed" over and over, to the point that doing a reboot was challenging since i barely had the time to press on the screen between instances of this bloody error message appearing...
...i did of course try and return to my older nandroid backup, but... lo and behold... exactly same behaviour...
so now i have resorted to formatting the internal memory card and flashing a new rom and basically starting over... just what i hope the nandroid would spare me basically :/
question is: does this sort of error sound familiar to anyone? can someone give me a tip maybe on what i may have done wrong?
any opinion, tips& advice much appreciated
I have the exact same problem. It happens on TW Lollipop ROMs. Haven't found a fix. I'm using Philz Touch Recovery and the old no knox bootloader.
Anyone? I have researched this but cannot find any similar problems reported... it can't just be me and pavelcheto...
Maybe it a recovery fault. Faulty backup or faulty restore.
No problems with my older backups. I restored my KitKat TW backup, working fine. Restoring CM12 backups also works fine. I've looked for a new recovery, Philz is discontinued, CWM hasn't been updated for a year and I really don't like TWRP.
I use TWRP 2.8.3.0 and never have (and hopefully never will) encountered any issues with restoring backups.
Considering i recovered 2 separate backups for a total of 3 times (i tried recovering the first backup twice) i doubt the issue was with the recovery itself... however since pavelcheto had no issues with the kk recovery maybe it could be lollipop related?
Anyone successfully recovered a lollipop nandroid backup?

I recovered my lollipop gpe backup a couple of times without a problem.
Data encryption may cause restoring problems.
I have restored CM12 backups (based on 5.0.2) serveral times, no problem there. I've had issues only with TouchWiz Lollipop ROMs, I have tried different custom roms, all get bugged at restore.

Just to make sure I understand correctly : you mean all TW custom roms you've restored have had problems?
Wonder if anyone else has managed a bug-free restore of a 5.x TW?
Yes, but only on Lollipop. KitKat TW roms restore just fine. I am using Philz Touch Recovery. I have tried 3 different TW Lollipop roms and they all fail to restore properly. No wallpaper, black wallpaper and no status bar. And after a minute or two System UI starts crashing. If then I do factory reset from recovery and the rom starts normally (welcome guide and stuff) and works fine.
bumping this thread because i cant seem to find a solution for this anywhere.

There's no solution for this as per comments above. TW LP is not restorable. You can flash a new lollipop ROM tho'

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.

XT907 bricked (probably partitions in read-only)

Good morning.
After almost 3 years with no problems with a XT907, I have again an issue with it (this time, my father's one). Again, I come to you requesting help.
It all started with all apps crashing over and over. With an old XT907 I have for emergencies, the common fix method is flashing VZW_XT907_4.4.2-KDA20.62-15.1_1FF.xml.zip with RSD Lite v6.1.5 and all solved.
I tried that method with my father unit, and when it started again, all process were still crashing. I thought it was still nothing (just a harder issue), and tried flashing VZW_XT907_4.4.2-KDA20.62-15.1_CFC_1FF_SVC.xml.zip, just deleting all his data, to fix it.
When the process ended, it turned on and it had still the same problem. In this point, I got worried the /system and /data partitions got locked
I re-started, went to stock Recovery, and wiped system and cache. Then, went to Fastboot a third time and tried again flashing VZW_XT907_4.4.2-KDA20.62-15.1_CFC_1FF_SVC.xml.zip. Guess what? Still the same problem
The phone turns on, but ALL apps keep crashing over and over. I can't even take an screenshot, as it immediately reboots.
Someone know what happened with it? And... how to fix this issue?
