Hello, i have a nexus 7 (2012) that started to act weirdly. restarts a lot just after booting. i tried to flash it with factory images, reinitialise it, hard reset it, flashing custom recovery, nothing.. it returns to the same position like it was frozen on that state. i tried also to delete some apps but they return after restart. it seems to be write protected or something. btw, the bootloader is already unlocked. please help

my shiny new nexus seems to be stuck in the boot loop of death...
it starts up, shows the google logo, then the nexus logo and then it just starts over... rinse/repeat etc...
i can get into the bootloader no problem, but since i have no roms installed my options there are limited to restarting the bootloader (does nothing to fix the problem), recovery (hangs on the google logo forever and does nothing, but at least does not loop) and shutdown...
again, i have no roms installed (haven't had a chance to yet)... this is pretty much a stock device with some games/apps installed from the market...
i got my nexus about 3 weeks ago from microcenter, so i have just under a week to fix this or i will have to exchange it for another unit...
so how bad is this ? fixable, or should i not even bother and just take a ride and exchange it ?
Completely fixable.
Have a look at wugfresh's toolkit if you havnt seen it yet.
It allows you to flash stock from bootloader mode which will wipe all your data, but fix the problem
So I just attempted rooting my nexus 7 (2013) the other day and after the unlock process rooting wouldn't process through (no SU installed). Anyway I was trying to flash back to stock using the nexus root toolkit. Now my tablet will not leave the bootloop mode, I can scroll through recovery, rebooter etc. but none of them work even with power>up vol., it will go to the black screen with google logo with a lock at the bottom but just freezes at this screen till I turn off/on. Any help would be much appreciated I feel like I have tried everything I've found to no avail. I have dl'd the 4.4.2 (KOT49H) factory image and tried the CMW recovery twrp but nothing is working.
Have a standard Nexus 7(2012), 18m old. OTA upped to Android 4.4.4. a month+ ago. Never rooted. From then on it has lasted a week or less before freezes/reboots while using apps or even nothing at all.
Have undertaken boots to fastboot mode (android on its back, door open but no red triangle) and then entered recovery mode to wipe system cache and then do a factory reset. This sometimes progresses thru startup restoring apps ok. Sometimes it crashes part way thru. Often get background Chrome and Maps crashes of late as it redownloads my old apps.
Google HW support line recommended this course of action until last time when desperate Indian woman out of her depth tried to say it was a hardware fault and palmed me off on Ausus(uk) saying they did a 2yr warranty... which I think they don't. Still to investigate that one.
The reboots kicked off again today. So did the usual: did a cache clear then factory reset and it restarted. Now it crashed while the Android coloured balls still rotating! And forcing into fast mode to do a 2nd factory reset failed as when I select Recovery Mode it now says "Booting failed" in small letters at the top and dumps u back in Recovery mode, though less the Android logo on its back. Cannot restart bootloader either, same error. Rebooting just freezes with "Google" displayed.
Have I "bricked it" somehow. How to I get past this?
As a novice, I have got Nexus Root Toolkit v1.8.5and tried to reflash to stock 4.4.4 rom on it. But bootloader is locked, as it is delivered, and it will not unlock it. (read from The Definitive Guide on How to Restore Your Nexus 7 Tablet (Even if You've Bricked It from nexus7 wonderhowto site)
Anyone got any info on what to do here? Better reflash tool/instructions? Is it hardware problem? Do Asus uk do a 2yr warranty that I need after 18months? Is this tablet permanently a dead parrot?
Any help, I am desperate here. Thanks
Hello guys, i'm having a problem ;f
I was on cm12 nightly when i decided to reboot my device after few days of running, strange thing happend and i ended up in bootloop.
I've downloaded 4.4.2/4.4.4/5.0.1 stock images and tried to flash it guided by the instructions in this thread, however i still get a bootloop, even after clean installation, even after wiping cache and doing a factory reset.. I've managed to boot up my device twice since yesterday, after getting stock image to work i pushed cm12 and gapps on my phone and flashed them.
At the first try, i got bootloop again, so i decided to go through the whole process again, many attempts later i've managed to boot up my device again, and again i decided to flash cm12 and gapps, this time my device booted up properly so i wanted to gain root access, in order to do so I flashed UPDATE-SuperSU.zip file and as a result end up in bootloop again.. I have no idea wtf is wrong with my nexus. I am still trying to flash factory image, and i always end up with bootloop.. I'm out of ideas here, HALP! ;(
@update:
I have uninstalled all drivers, and mount my device to another usb port, then with NRT i installed google's drivers, by using nrt i have flashed 5.0.1 factory image, rebooted into recovery and wiped/factory reset, after that i rebooted my device and still no luck - hanging on floating dots for 15 minutes..
Before all of this I tried formatting my cache to FAT and to sdf4 and it didn't help, I literally tried every single instruction i could've found ;/
What's wired is that when i encountered bootloop yesterday and wiped/factory reset i booted fine, after restart it went into bootloop again, so i thought i would wipe/factory reset again i'll be good to go, but.. it didn't help this time oO
things i've already performed:
1. fastboot oem lock/unlock
2. wipe data/cache/factory reset
3. flash factory images of 4.4.2/4.4.4/5.0.2 through NRT/manually
4. converting partition to fat and next to sdf4
5. reinstalling drivers
6. different ports and usb cords
6. i even tried switching motherboard from my old n4 and i still stuck at bootloop *LOL!?*
7. after 6 i thought it may be related to usb port so i switched usb port from my old n4 and it did help but.. until next reboot ;/
from time to time, after flashing it boots up just to make my hopes and then it gets the bootloop after restart ;/
@update2:
It seems it's hardware related issue. I have tearn down my nexus device and left only motherboard with fron/back cameras and audio jack, daughterboard, i even disattached the speaker along with antena. At this point i flashed factory 5.0.1 and it works, i'm in the moment when i plug peace after peace and turn on the device to check if it still works. I'll update when i find out what was the cause of the problem.
@update3
Stupid as it sounds the issue was caused by the vibrator module, while it was disattached, the device was booting up without any problem.
Good day! I wanted to ask how to remove the bootloader for zenfone max (the old one 2015 model) without using the app from ASUS as I cannot really use my phone. It boots then restarts. I already tried Wiping/Factory Data reset and Wipe cache with the Power and Volume down (Is it Recovery mode?) but still bootloops, by the way when I factory reset, my phone showed "Unknown volume for path /factory". My friend told me it could be that my OS was corrupted. So here I am wanting to unlock the bootloader so I could install OS for my phone.
**Note1: Sometimes it would boot to the "Welcome!" screen, then when I reach to the Wifi selection, it would always restart.
***Note2: This bootlooping happened when I restarted my phone because my wifi suddenly couldn't connect. After I restarted, it looped.
Noob here btw. Sorry and I would be glad to provide additional information if needed be.
