[HELP]My nexus 4 can not boot even after flash stock image correctly several times!

Hello everyone, I thought I've got a big problem here...
My nexus 4 originally crashed and stuck into a boot loop several days ago, and I flashed stock factory image(4.4.2), then it works again. After that, I imported my backup files into internal storage and using titanium backup restored my apps and data, unfortunately, crashed and boot loop again...So I flashed stock factory image again to find out what reason of this. After several restore from stock factory image, I found that my sms message and many mp3 files could lead to crash, after flash factory image, works fine, use it, reboot it ,fine, but after copy many mp3 files and restore my sms backup(about 2,000+ messages), reboot, stuck into boot loop... Now I try to flash stock image again, however, with no luck to boot my phone...
During my privious several times of flash stock image, it's always hard to boot the machine normally at the first time, I always try to wipe cache, factory reset in recovery even several times to manage to boot the machine normally.
This time when I flash stock image again, I just can't boot my nexus 4 anymore, even wipe cache, factory reset from recovery, whatever other tries...:crying:
Now I even tried several ways to flash stock image(4.4.2, which I used to managed boot up before):
1 Using the newest Nexus Root Toolkit: Boot into bootloader mode and click "Flash Stock+Unroot(soft bricked/boot loop)", everything says OK, however, it just can't boot and stuck in Google logo screen, even after I waited for 2 hours...
2 Using the flash-all.bat: Extract the .tgz image file into a folder which contains adb.exe and fastboot.exe, then execute flash-all.bat, everything reports OK, but just can't boot up, still stuck on Google screen.
3 Manually flash: Extract the .tgz and the .zip, put all files(including boot.zip, system.zip, recovery.zip etc) in one folder, flash bootloader and radio first, then "fastboot flash [partition] *.img", and everything says OK, just can't boot up and stuck on Google screen.
4 Manually flash using 3rd party recovery: Have tried to flash newest CWRP recovery and CMOD recovery separately first, then do manually flash as above.
I even do:
fastboot oem lock
fastboot oem unlock
fastboot reboot-bootloader
fastboot erase system(or fastboot format system)
fastboot erase userdata(or fastboot format userdata)
fastboot erase boot
fastboot erase recovery
fastboot erase cache(or fastboot format cache)
these commands before I try to do the four ways to restore factory image above, but nothing changed.
Now stuck on Google screen, what ever I wipe cache/factory reset how many times, it's just stucked... I even doubt if my flash memory was broken???
PELEASE HELP!

Flash CWM, wipe the partitions there (But not /boot or /persist, those will hardbrick if you reboot after wiping although I don't think it will let you wipe them), flash the latest radio (.98), and then flash a 4.4 ROM.
If that doesn't work, wait for more responses from others, then try this as a last resort. I suggest that you wait a few days, this can be dangerous
http://forum.xda-developers.com/nexus-4/general/tutorial-how-to-unbrick-n4-t2347060
Follow carefully, and read multiple times before starting. Take it slow and don't panic if the process doesn't go as expected at 85% (Mine wouldn't reboot on its own for some reason, it kept erroring but it was fine and worked itself out)
It should put the phone on a complete clean slate for flashing

Thanks for your reply

Hi lopezk38,
Thanks for your reply! And I do as your instruction:flash newest CWM recovery, then factory rest, wipe cache, and under mouts menu format system/cache/data and firmware(but error), then flash a latest CyanogenMod image for nexus 4, with no luck, everything remains the same
However, I saw the link you provided to unbrick nexus 4, I'll read it carefully several times. At the same time, I'll wait for any other kind help that anyone can provide. If finally there is no other way to repair it, I'll go through with your link.
Thanks again for the tip!

Yeah /firmware was another that won't wipe, I just forgot to mention it. Best of luck

It sounds like you have faulty nand block (s). Before no critical parts of the firmware got written to it, so it developed problems when you wrote data to it. Looks like this time you didn't get so lucky, or more failed. If it's under warranty I would RMA it; if it's not, I'm honestly not sure what your best option is. Maybe get one that has broken screen etc, then do a logic board transplant. Good luck.

Hi, I've carefully read the link several times, and finally go through with it without any problems, and I could flash 4.2.2 stock images and do the 8gb to 16gb part to restore my phone to 16gb storage...However I found that I only can flash 4.2.2 image to make the phone boot up normally, with 4.3 or 4.4.2 image, it fails at boot up. Most important and sad part is, when the phone complete initial setup and install some software, it crash and can not boot again:crying: I've given several tries but the same result.
Finally, I made decision to sold it to buyer who needs only a good glass screen for replacement purpose... Farewell, my nexus4...

[Q] Can't finish write to userdata

Nexus 4 with stock (originally 4.4.2), which wouldn't update to 4.4.3, due to TWRP being installed, so when 4.4.4 came around, thought I would download and flash myself. Not a huge expert, but have certainly flashed several phones successfully previously.
Initially using the Nexus Root Toolkit, unrooted etc, downloaded the correct file from https://developers.google.com/android/nexus/images, tried to update, and would not write the radio file (waited for ages), tried to do using adb etc, no go.
Finally downloaded the 4.4.2 image, and using fastboot, this successfully did everything up to userdata, erased userdata successfully, and sent file, but never completes writing. (writing 'userdata'...) If I reboot, just gets stuck on the 4 circles.
Have installed CWM and tried doing a factory reset, but can not mount data....
Anyone able to assist?
Thanks

Panic over...
Perseverence seemed to pay off. Just did more of the same, and tried installing the userdata by itself. Seems to have worked.
But now am stock, and still doesn't seem to want to install the updates....

Well, thought it was stock, but the latest OTA didn't install. Don't really know why, as I wasn't watching, but it did the download, then kicked off the install, but when I came back to it, was just sitting at the home screen, no messages and the update hadn't happened - still sitting on 4.4.2.
I had flashed 4.4.2, and I thought the only bit that hadn't worked was the userdata, which I flashed separately, recovery has been flashed to stock recovery...
Why hasn't it updated?
And how can I tell if 'everything' is stock?
Thanks.

I need your help guys. (bricked nexus 6p)

Okay, so I've been reading XDA for a while now to root my devices and install custom ROMs and its been incredibly helpful. However I have a huge issue with my nexus 6p and can't find a way to solve it.
Here goes....
I bought it of eBay a few months ago and unlocked the boot loader and rooted the phone plus i also installed twrp and made a nandroid backup. I then installed pure nexus rom and the phone was working incredibly well.
Fast forward to this week, I decided I wanted to upgrade to cm13, since I missed the cm theme engine. So I Wiped my device clean using twrp. And installed cm 13 and the gapps then rebooted.
The phone booted perfectly but on the optimising apps screen it would reboot and tell me to enter the password that I originally had on the pure nexus ROM. After doing so it would re optimise the apps but would crash and reboot. It was doing this continuously.
Twrp also asked for this password on every boot before it let me see the main recovery menu.
So then I took the logical next step and decided to wipe the phone clean again using twrp. Seeing as my password seemed to not clear the first time.
After the wipe, I decided to use the original nandroid backup to restore my device as the password thing was still showing up. And cm 13 was still not installing. Neither was pure nexus.
Okay this is where it went downhill. I hit restore and had everything checked. The process was going well but instead of the restore completing and twrp saying it was successful. It crashed halfway and rebooted.
Since then its stuck in a bootloop. Its on the google splash screen and then reboots to the google splash screen continuously. And does not boot to the os.
On another note. The bootloader is still unlocked. The recovery works. And so does adb/fastboot. So I wouldn't consider it hard bricked.
Here's what I've tried so far:
I've used the wugfresh root toolkit to flash stock and unroot the phone. With softbrick checked. Still nothing. Phone boots to the splash screen and then reboots to the splash screen.
I then reflashed twrp 3.0.2-1 . which worked And its not asking for my password anymore.
Again I tried restoring from my nandroid and it crashed midway which makes me think the nandroid backup is/was corrupted causing the issue in the first place?
I've also tried to just restore and Flash twrp again and then install pure nexus ROM. And still nothing?
I can also still mount my phone to the PC and copy and remove files.
On another note I find it interesting that although the ROM is installed. And the storage bar on my PC is partially filled showing that it clearly has a ROM installed. The phone does not have the standard android file system. Just the twrp backup folder and that's it.
I would be honoured if you could help me out here. And get my 6p up and running again.
Thank you . [emoji45]

I would suggest you flash the factory stock system image using fastboot to get your 6P back up and running.
If you don't have the factory image they can be downloaded from here
Extract the factory image then use fastboot to flash
Code:
fastboot flash bootloader C:\angler\images\bootloader-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash radio C:\angler\images\radio-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash boot C:\angler\images\boot.img
fastboot erase cache
fastboot flash cache C:\angler\images\cache.img
fastboot flash recovery C:\angler\images\recovery.img
fastboot flash system C:\angler\images\system.img
fastboot flash vendor C:\angler\images\vendor.img
Check out this guide which has all the information you need, especially around device encryption and flashing roms. Lastly gaining root is as simple as flashing SuperSU or Phh's SuperUser in TWRP.
I hope that helps, let me know if you get stuck.

Yea just flash stock image I had this happen to me before and flashing stock image fixed it.

Thanks guys. I'm going to read the guide and try it out. Then let you know how it all goes. Fingers crossed it all works

FYI don't backup efs partition with that version of twrp. It's a known issue.

i did not realize that twrp had that issue
And guys, I followed the fastboot process by the letter and although everything worked well. The nexus 6p is still bootlooping on the google splash screen and not going any further. :crying:
What should I do? i've added the cmd window screenshot so you guys can have a look.

Upgrade to TWRP 3.0.2-2 real quick. You didn't need that guide(in terms of his nandroid) but I am glad it worked. Just need to wipe efs partition using adb commands.

I see. And I have upgraded to the latest twrp so hopefully it doesn't not happen again

Good deal!!! There's a build that's unofficial of 3.0.2-3 that you can also jump onto. The current version 3.0.2-2 has a bug with backups on Android N. There was a comprehensive post that someone made about the issues with the different versions but I cannot find it for the life of me.

Cant get out of TWRP

So i just did the new update on my V20 and it sent me straight to TWRP and i cant get out of it. It always boots into TWRP. What can i do? ive already tried a factory reset and restoring my back up and nada. Help please.

Its now looking for stock boot image which on yours is currently modified with system rooted.
Try using lgbridge to repairs your boot image or if you have it flash the stock boot image using fast boot command or do a factory reset while in twrp then flash entire stock image with lgbridge.

Yeah none of those work. The OS is setting off some sort of flag that states it must go into recovery and wont stop going into recovery until that flag is changed which I assume is done by the update. I tried updating with UPPERCUT/LGUP and it errors out at 4%. So right now it's still stuck

It didnt install the update
type
Code:
fastboot erase fota
from bootloader and see if it boots after that.

This will for sure fix you up...
https://forum.xda-developers.com/v20/how-to/how-fixed-bricked-lg-v20-t3501310

listen to me2151
delete fota and then pull battery and reboot.
ota's downloaded to the fota folder will cause endless twrp loop.
freeze ota in system/privapps to avoid this again.

Sorry to post on here, but maybe we can get a few tips from each other.
Im also stuck at TWRP. I installed a ROM and went back and forth between both ROMS. After about 4 times of going back and forth between ROMS, my pattern didn't recognize on boot with my original backup and daily. I tried my pattern over 10 times and it wiped everything on me. The strange part was I was swiping my pattern 100% and it failed. Also, my tries were going up and down. It would say I have 6 tries left before my phone wipes, then I would stop anjd turn the screen off, and the screen would say I have 3 tries left, then 5 tries left. My tries were inconsistent, and it finally wiped everything.
I am now stuck on TWRP with no luck of restoring. I flashed the vs995 boot image and system image and it goes back to TWRP. I factory reset, wiped everything, made sure the system folder was clean, then flashed both images again and the same thing, no luck.
I also tried to restore with LGUP, but keeps stopping at 9%. I extracted the dll and copied it into the common folder and I get the same thing.
Error: Error Code = 0x2000, Flashing Fail
When I plug the phone into my computer it shows us996 and not vs995. Strange.
Any help would be amazing.
EDIT: Figured it out!
So, I extracted the dll file from the kdz file and I had to replace it with the one in the common folder. My error was not renaming the file, so the LGUP would stop at 9%. Make sure you pull the file, rename it, remove the old file from the folder, and flash on LGUP.

Nexus 6p bootloop (NOT same as Infamous BLOD)

Hi! Guys I have a problem, which doesn't resemble the BLOD, so here is what has happened. I was running stock android June build on 6p, rooted. And my phone started random reboots. I thought it could be fixed with either stock or custom rom. So I decided to flash AOSPA. I went into twrp but could not flash it, phone rebooted each time. I tried stock images via flash all command as well as manual. No rom worked although I could flash kernel etc. I used The Flash's custom twrp and fixed data and was able to flash rom easily, but it bootlooped on google logo, and rebooted. Now I can flash roms etc but it bootloops. Although Tesla rom did go into bootanimation before bootlooping.
So what can I do? Is it software related? What do you guys say!
PS. I did look into other threads, nothing was similar, although I did try a few mentioned fixes.

Use fastboot to FORMAT system, userdata and cache. Note any errors during the FORMAT process.... and then try flashing a full image from Google using flash-all.bat

I'd say you were squarely in a small group of people who are able to access and fully use Recovery but still boot loop after formatting and installing a clean image. If you've already tried a factory reset from the stock recovery I think you are done. Hardware issue. Replacing the motherboard is a fix, but not economically viable.

I had the same issue formatting data and cache to Ext4 and flashing modified stock ROM fixed. It would boot to Google logo freeze reboot and sometimes get to boot animation freeze and reboot.

Cortex ROM it's flashable stock firmware with extras . Though my symptoms where the same I hope I'm not giving you false hope. Worth a shot though.

The only was I recover my phone without replacing is using https://forum.xda-developers.com/nexus-6p/general/boot-images-bootloop-t3633723 < method from here... but the phone is lag af as it is only running 1 core on stock july build. Good luck for that.

I have the same issue going on. i was trying to flash magisx and suddenly it is stuck in bootloop. i tried flashing stock images and everything. i can access twrp and flash eveything and they are getting flashed fine but still it is stuck on the bootloop.

So have you used fastboot to FORMAT system, userdata and cache? Did each format command complete with no errors?
