[Q] Help with bootloop - Nexus 7 Q&A, Help & Troubleshooting

Hi folks,
I'm having some issues with my Nexus 7 as it's stuck in a boot loop on KitKat. It's still under warranty and it's unrooted. I'm at the point of sending it back but I just wanted to check if there were any suggestions coming from helpful folks around here. It's only a couple of months old but it's a refurbished device that I got on the cheap.
A factory reset with only the default Google apps on it still initiates the boot loop. However when I manage to restart it in safe mode it seems to be stable. I've read some account of battery connections being the cause but if this was the case then I would think that it would still restart in safe mode.
So if there anything else I can try or should I just go ahead and return it?

Better go for a replacement...

[Q] Note 3. Suffering from bootloop after TWRP restore

Recently I just sent my phone to warranty for my S-pen,samsung changed my board and sorts things out.
When i got my Phone back i restored my twrp back up, nightmare happens afterthat,bootloop all the time apps force close,.systemui has stop. I tried flashing stock ROM,format my phone,wiping all data and cache and even my SD card.
I went back to samsung today and my warranty is over they checked thgs out and said that its my battery problem,should I get a new battery or is there anyway to sort my bootloop problems? I just got my phone for one year and i cant afford a new one. pls help out
Hi, thank you for using XDA Assist. I would flash your stock firmware with odin and then not restore your nandroid. I'm going to move your thread here, http://forum.xda-developers.com/galaxy-note-3/help where experts on your device can help you.
Good luck and welcome to XDA.

Help with Note 4 boot loop...

Phone: Note 4
Version: 4.4.4 custom rom
Model: SM-N910F
Hi all looking for some advise. Rooted my phone a long time ago and never had a problem til recently. Within the last month my phone keeps going into boot loop and I need to put on charge to stop it, even if I have battery. Certain apps like the camera cause the boot loop and sometimes its just random.
Just wondering the best way to stop this? Isit safe to just install another custom rom over the one I've got and will that solve the problem? Haven't played around with custom roms in a long time so can't remember anything.
Any help would be greatly appreciated.....
Any suggestions please I'm desperate? Just getting worse my phone has to be on charge now or it goes into the boot loop every 10 mins or so.
make a nadroid backup and do a factory reset thru the phone settings? I'm thinking it could just be a misbehaving app update, if you didn't make any new modifications to your note 4.

I did that yesterday and it's helped a little. Still get the boot loop but not as often. The camera is usable now but I'm still getting the boot loop sometimes..... Any other ideas?
Install a different custom ROM or simply Odin flash a stock firmware.
Instructions of installing a custom ROM is stated in the OPs of the ROMs.

Anybody else have a main board failure? Here is my story.

Last week I was minding my own business, doing usual stuff on my phone and the device spontaneously rebooted into a bootloop at the Google logo. So I think "OK, no problem... I can try wiping cache/dalvik or at worst I have a recent nandroid backup" and proceed to reboot into recovery... except that it still hangs on the Google logo. Stuck at work I did a bunch of googling and found one other user who had the same thing happen recently.
When I got home I tried to fastboot flash TWRP again... but alas was still stuck at the Google logo. Next was a full flash of Google stock images, but that did nothing either... so I relocked the bootloader and had my provider (TELUS) send it in for warranty repair. I just had it returned with the repair stating the main board was replaced.
I have noticed a few users posting about being stuck on the Google logo and this concerns me a bit, as it almost seems like there may be some inherent hardware flaw causing the issue.
So I'm throwing the questions out there: Has anyone else had similar problems and is this something we should start to be concerned with?
You're not alone buddy. I'm in the same boat. Have sent mine for repair yesterday.
Thats discouraging news. How long have you guys owned the phone? Did you buy it new?
I love my 6p but if enough of these units are defective they should probably be recalled. Hard to gauge if its an anomaly or a serious issue. Hope for the former...
I think I may have the same problem. My phone wont boot past the logo at all. IDK what to do at all.
I have the same problem, stuck on the google logo, I already wiped the cache partition and nothing, did a factory reset and nothing, what else can I do??

Check if you can boot twrp. If you're not successful send the phone for repair. No option available to recover from this king of hard brick yet.
Weird thing is anything and everything is doable in fastboot. Moment you try to boot OS or recovery, gets stuck indefinitely in Google logo and reboot.

this exact thing literally just happened to me on Thursday. I was fully stock never unlocked the bootloader or anything. phone suddenly started looping, tried wiping cache, doing factory reset, finally went nuclear and unlocked the bootloader and flashed system images. nothing worked. warranty replacement is enroute.
I bought it on release day.
Old issue with Nexus devices. Has been going on since Nexus 5

I got the phone new from TELUS at the end of December, so about 6mo before I had the issue... Thankfully fastboot still worked so I could return to stock and relock the bootloader before warranty claim...
Starting to wish I had done the insurance option if these things are failing after 6mo and I'm on a 2yr contract

Did they give a new/refurb or was it they changed motherboard/memory chip?

Was my original exterior, the dings were still on the corners so it was just motherboard replacement

Thanks. Just was curious on what I could expect.

I'm also having this issue, but I get stuck at the boot animation instead.
I have Nexus 6P, Stock Android 6.0.1 July, SuperSu v2.74, franco kernel r23, Xposed v85. Everything was running fine when suddenly the phone rebooted and got stuck in boot. I reboot into recovery, deleted the /data/data/de.robv.android.xposed.installer/conf/modules.xml, flashed xposed unistaller zip, cleared cache and rebooted. Still stuck in boot. I reboot into bootloader, flash boot, system, vendor image of July factory image and reboot. Still get stuck at boot. This is happening for the third time to me. Happened in May, in June and now in July. Only thing that works is restoring a nandroid and then again flashing the latest factory image. But that way, I lose days / weeks of data, depending on when that last nandroid was created.
That really sucks, but doesn't sound like a hardware failure from my understanding... I lost ALL my data when I had to send it in, since my failure resulted in no access to the internal memory... Lost a few pictures which was a real bummer, but lesson learned and now I'll be backing up my memory more frequently and also setting up cloud backup for photos

It's likely a software failure. When you flash via fastboot, do you reboot back to bootloader after flashing radio and bootloader? If not then that's likely what's causing the fast boot method to fail for you. The first time after I did a complete fastboot flash of the software I fell asleep and woke up in the morning to my 6p still at the boot screen. When I re-traced my steps I found out that my mistake was not properly rebooting after flashing radio image, then doing another reboot after flashing bootloader.
Got my device back. Same exterior. Was told that motherboard was changed. I could notice that from fastboot.
eMMC changed from Samsung to Toshiba
DRAM changed from Hynix to Samsung.
My device joins this list. Gonna send it for repair tomorrow and hoping it is covered under warranty.
Additional update. I know I missed the bigger scheme that changed. My IMEI.
Just curious what happens if I restore my previous efs partition backup after backing up current.

my phone randomly locked up, then rebooted today. But when it rebooted it was stuck with the white google logo flashing. I can get into the bootloader mode, but from there, choosing recovery or anything else gets back into the white google bootloop. I called service and they're sending me a replacement. Phone was stock with a locked bootloader.

[Noob] Nexus 6p bootloop Help

I sincerely hope there's something else going on but it is most likely the well documented problem with no fix. Heres just one thread of several. This one's right from this very section of the forum
https://forum.xda-developers.com/nexus-6p/help/boot-loop-death-nexus-6p-t3533528
Hope this isn't your issue but if it is I hope you're under warranty....
Side note--this really sucks. I've got like 2 months left under warranty but think Google should extend that if they can't find a fix. Ive had no issues-best phone ever for me personally but of course that doesn't count for much if its dead after a year.

Is my phone bricked?

Hi!
So i've recently had some issues with my Samsung galaxy s8+
With the introduction of the new Pie Beta update i thought it would be cool to try it out!
I had to downgrade my firmware and so i did via ODIN.
This failed initially duo to a bad cable, i quickly replaced with OEM one.
Alright! We are able to boot into the OS, i stuck my SD card in the phone and updated its firmware succesfully.
HOWEVER; My phone would reboot once in a while out of nowhere and i figured i was on a Beta that might cause issues
started removing all of my apps in hopes it would help. Unfortunately in either safe mode OR clean factory wipe.. I was still running into reboots.
Alright ok, eventho no one on the forum complained about reboots.. I'll take my loss and i'll just flash back to stock..
However; it seems like the phone just freezes up now in everything!
Freezes up in Download mode; Freezes up during boot of new OS
i was able to reflash via ODIN by the way it just wont let me load into the OS. I've tried different ROMS
I can't wrap my head around it!
Should i just take my loss and buy a pixel 3 ? i was hoping to extend my contract with the new Samsung Galaxy S10+ but i can't do without a phone for a month.
Thank you in advance!
UPDATE:
I've succesfully been able to load into the OS at the moment. Let's see how long this lasts!
Aaand about 6 Minutes later i get a reboot
Yeaaah, it's dead.. After rebooting more and more frequent
It doesn't turn on anymore.
