Bootloop after backup - Nexus 6 Q&A, Help & Troubleshooting

Could use some advice here guys. I'm stuck in bootloop from simply backing up my system. It seems anything I do in twrp other than doing a reflash of the Rom and gapps is bootlooping me. Again I can flash fresh and start over but I can't do anything else in twrp without a loop. I even tried restoring the phone to the backup that I made just before the loop

From bootloader, enter the following fastboot command:
fastboot format cache
See if that helps.

By chance..... did you save your backup to an OTG drive?
Sent from my Nexus 6

No I did not. Any chance it's a corrupt version of Twrp?

Doubt it.... I had the same thing happen when I did a backup to my flashdrive.
I ended up clean flashing and downloading all apps.

Tried.... didn't work. That really screwed things up. That's why I had to clean flash and download my apps.

Nope. All I did was clean flash. I don't know what happened. It happened during the backup though, that's all I know. Had to clean flash to get back up and running. Also, it was rastapop that it happened to. I am running euphoria now.

I downloaded twrp in the play store. It has an SD fix on it and I re installed the latest twrp recovery. It seemed to boot up after doing dalvik and cache but not after backup. Issue still remains.

I've tried that mate. I've deleted all backups and done fresh installs of a few different roms, but to no avail. It's got to the point that I have to keep updating my backups because the phone becomes unusable so often

If nothing helps then you can try this as the last option. You can reflash your firmware via Odin then custom recovery after rooting your phone and finally the custom rom you are using.

How exactly you perform clean install? And what scripts you flash?
Try going back to a stock ROM release, then flash CWM via ODIN and from there, a rom of your choice

I flashed SlaidyBoostV2.3, it made my phone completely unusable. I flashed the Beats script too, and that had the same effect.
I perform a clean install by wiping data and cache/dalvik. Then I flash the rom and repeat the wiping process. Am I doing something wrong?

I'm having trouble getting the stock firmware for my phone. It says the firmware is for SIM unlocked phones, and my phone is locked to one network. Looks like I'm gonna have to get my phone unlocked. I'll do this as a last resort if I can't find a solution.

[Q] Constant Restarting

Hi, I'm new to this whole Android business, and got a HTC One about a month ago. I rooted + unlocked my bootloader + flashed with ARHD. Everything was going fine till about a few hours ago, when my phone restarted by itself and basically entered a constantly restarting loop. It'll get to the main page, where I can see the top status bar (i.imgur.com/rLbIFVl.jpg) and then restart. I guess the easiest solution would be to do a factory reset, but I have data on the phone that I need. Is there a way to retrieve this data without losing it? I can get into recovery and make a backup and everything, but the problem is I can't access the data on my phone...
Any help would be greatly appreciated!
Reflash ARHD, AFAIK, it wont wipe your /data partition.. Good luck!

Reflashing didn't work. I managed to back up my data, but now I don't know what to do. I tried a factory reset, flashed back to stock, and still no go.
Hope someone can help!
Do you have an RUU for your region/carrier? Flash the RUU if you can.. Or else search for a nandroid and flash it from recovery..

I used a nandroid backup I made when I first got my phone. I'm not sure if I screwed up somehow, but it's not working either...
Can you explain what exactly happens? And a little more details about your phone..

My phone boots up, but only to the screen as per the attached image. Then a couple of mins later, it restarts again. In an endless cycle.
As for details, what other details do you need?
Try downloading a fresh ROM (try trickdroid or sth), check the file hashes after you're done downloading. Boot into TWRP, do a full wipe, it will wipe the phone clean. Then ADB sideload the ROM (Google it) and then flash.. That should work.. :thumbup:

[Q] AOSP Alpha Build 6 ROM install failure

This is my first time installing a custom ROM. The phone has been rooted for some time now. I downloaded the AOSP ROM and GAPP 2012011, and flashed both packages. I did not use any third-party software to flash, and it appears the process was successful. When the phone reboots, it hangs at the point where the glowing X (like when my Nexus 7 starts up) appears, and nothing else happens.
Where did I go wrong?
Thanks to anyone who has a suggestion.
Maybe it was a corrupted download or you forgot to wipe

Did you forget to wipe your data, cache, and dalvik cache before you flashed. Also are you sure your downloads are not corrupted :cyclops:
Assuming you mean this AOSP right http://forum.xda-developers.com/showthread.php?t=2081011&highlight=aosp
I would just use Supernexus 4.2.2 plus AOIP kernel whitescreen fix or if you want 4.1 use camcorys 4.1.2 build
Also what recovery and build are you using?

I don't know what you mean by recovery. I used the file AOSP_ancora_tmo_tim1928-4.1.2-Build 6.
And no, I did not wipe the data before I installed the ROM the first time. However I have tried that, and then reinstalled the ROM. Same results.
I feel there is some app or more detailed procedure to installing this ROM, but I don't find specific instructions anyplace.
Thanks for the help I've gotten so far. Any other pointers or suggestions?

Please help with endless boot loop animation.

My phone was unlocked and rooted but running the factory 5.1 ROM. I had a 5.1.1 update this morning but it erred during install. I removed the root using Kingo Root and that's when the endless boot looping began. It appears as if my phone now both locked and unrooted but won't complete the boot process.
I tried unlocking the phone again using Nexus Root Toolkit but it tries to boot the phone, so I can turn on USB Debugging maybe, which doesn't work so I can't find a way to unlock my phone at this point.
I tried flashing a factory image using Nexus Root Toolkit and get the below errors. Nothing changes after completion.
TWRP will not install, I assume because the phone is currently locked.
Can somebody please give me some options to try? I'll do whatever works. I don't mind stock rom, I don't mind a custom ROM. Anything that works is OK with me.
I would love to get TWRP on there if possible.
I think my first step should be to get the phone unlocked again but is there a way to do it with a phone that boot loops constantly?
Thanks.
Also, doing a wipe and reset in recovery didn't help at all.
If fastboot format userdata and cache doesn't fix it, there's nothing you can do.
This is the image I get when I try to unlock using Nexus Root Toolkit. Obviously the boot loop starts and I'm unable to complete the unlocking procedure.

Install twrp over adb?

Did you fastboot format userdata and fastboot format cache? If so all you can do is send it repair.

Think what you will. But the answer is no.
I have two options in recovery; Wipe Cache Partition & Wipe Data/Factory Reset.
I've done both and it still boot loops.
So this phone needs to go in to the shop for service?

If you don't even know what phone this is, please stop giving advice and leave it to the people who know the phone and the options.
1) following incorrect and useless advice wastes time
2) it detracts from real advice
3) is dangerous

Sorry my bad. I just used fastboot to format userdata and cache. Restarted phone, still in boot loop animation now.
Never said that this is one
Lol
Sent from my GT-I8190 using XDA Free mobile app
fastboot format userdata and cache is your only option.
It appears that the boot loop is still present after fastboot formats.
There is nothing else I can try, correct?
If not, I'll take it in.

[SOLVED] Problems install custom ROMs

Is there a proper way to install roms? Okay let me refrase that... I dont think ive flash twrp correctly because whenever i install a custom rom it doesnt boot. Ive wiped and full wipe before flashing and even tried flashing from internal sd to ext sd with no avail.*
I flashed twrp through Flashify.
I'm so excited we have root now! Im so thankful for you guys that put your time and effort for us!
Thanks devs!
Edit: just a bad download

Sent from my LG-H811 using XDA Free mobile app
not sure how you tried to install TWRP, but make sure you hit "recovery image" to flash TWRP and not "boot image" on flashify.
hope this helps.
I reflashed the recovery and the same result...
I tried flashing the same custom ROM twice in a row and went back to the main menu of the recovery then power off. i turned it back on and it booted into the ROM.
so i tried a different ROM the same way and its not working again...
I have no idea whats going on here. this is so weird
looks like the stock rooted rom is the only one the flashes flawlessly
Redownload the twrp file and flash it through flashify also are you just flashing the ROM and not doing wipes
Sent from my SM-G386T using Tapatalk
Did you check md5 of the rom that keeps failing? Sounds like a bad download.

it might help if you outlined exactly what you are doing, step by step
also what rom are you flashing?
