[Q] HELP! Partition lock

Hi all,
My nexus 7 has flashed with PA 3.65.
Now, I want to back to stock 4.2.2 ROM. I use the two tool kits-- Nexus 7 Toolkit and Nexus Root Toolkit
But my device is like locked, I use all kinds of commands to erase/flash it, my device is still run as PA version.
Go into TWRP and factory reset, the PA system still exist...
Use the Toolkit to flash, the PA system still exist...
Use adb/fastboot command to flash recovery image from TWRP 2.5.0.0 to 2.6, it always run as TWRP 2.5.0.0.
I feel my nexus 7's partition is locked, I can NOT add/delete anything. For example, if I delete a file in internal storage, the file will appear at the next reboot. If I add a file in internal storage, it will disappear at the next reboot time.
Anyone can help me? I have no idea to solve it.:crying:

Download the Nexus 7 4.2.2 factory package and unzip the contents to your ADB/Fastboot directory then reboot your device into Bootloader. Start > Run > CMD > cd (your directory) e.g. "cd c:/platform-tools" > "flash-all.bat" will your erase all current partitions and replace them with the factory images including the recovery, system, boot, data, etc.

The package includes the stock recovery, not a custom one. You can also flash stock images individually such as the system and data, which will restore the stock OS.

Yes, I know the package included the stock recovery. I flashed it, but it didn't restore my nexus 7 to stock OS. My nexus 7 always running in PA ROM even I flashed all stock images.
thanks!

[Q] Updated Nexus 4 with Android 4.4 Factory image. Only seeing boot animation

Hello,
My name is Rahul. This is the first time I am posting.
I flashed the latest factory image for Android Kitkat onto the Nexus 4. the image was occam KRT16O. I followed the instructions and used fastboot on mac and ran the flash-all.sh script that was provided.
The log of the script was as indicated below and the device rebooted. However, it was stuck in the boot animation for a long time.
What can I do next? The options I can consider are:
1. force reboot the nexus 4 by holding the power button [if that would work] and flashing the image again.
2. go to the bootloader (if reboot works) and switch away to the previous ROM (I was using CM and PAC for some time now flashing them nightly) and wait for a new more days.
I would love to try the new factory image for KitKat on my phone and would appreciate if you could provide some direction.
Thanks in advance for your help.
- Rahul

I opened the zip file image-occam-krt16o.zip and found userdata.img and i used fastboot to flash userdata with that image. I am still waiting for my phone to move ahead from the boot animation...crossed fingers.

I guess that you, like me, took the wipe flag off the fastboot bat file right?
Well I was told that 4.3 --> 4.4 needs a full wipe so I put that -w back in place and everything works, my 4.4 works
and my phone looks fresher than fresh.
Good luck

opssemnik, I downloaded the file again, unzipped and tried again. It gave me the same log. I then opened the zip which contained user data.img and flashed it and it still waits at the boot animation for a long time. I think its already been twenty minutes.
Is there anything else I can try?
Thanks for your response.

Yes. The flash-all.sh uses -w which fully wipes the device. I remember reading about -w somewhere.

I had the same problem, came from PA 3.99 and flashed the kitkat google image and phone got stuck in bootloop. Only way i could fix it was to get the new sdk studio and use the fastboot from that

the last log u gave looks like mine so i guess its ok, but u were using a really outdated adb huh? im using the minimal adb + fastboot from like 6 to 7 months ago(so the fastboot / adb is from that time witch means is old) and i can flash the stock images

can you send your "platform tools" somehow? I downloaded everything today and tried flashing 4.4. Stuck at boot screen. How long did you have to wait before it went past the boot screen?

just ask him for the link as of which he got it from probably easier.
Edit: May I ask you guys a question if you skimmed through this forum prior to making a decision to upgrade you would see so many people with the same issue and post day in and day out about flashing images. I am confused as to why those of you want to flash images instead of just flashing through a custom recovery. There is no difference? other than less headaches from what I see

Already tried that. Didn't work. Always gets stuck at the boot animation. That's why I thought of trying a different recovery. Neither works

May have to start from scratch since this is how all others have gotten past that screen or simply why not flash a zip. So much easier than dealing with images

Can't wipe or factory reset Nexus 7 (2102) using multiple methods

A month or so ago my Nexus 7 (2012) started rebooting itself after a minute or so of turning on - I think this may have been during OTA upgrade from JWR66Y to new release. I tried to fix this by clearing app data and booting into CWM recovery and deleting cache and dalvik cache but the problem persisted. So I decided to reset the Nexus 7 back to factory image and have tried every means of doing so but every time I keep getting back to my original data and the app crashes and reboot continues. I have never had any issues connecting to the device on USB and ADB so this is not a driver issue. Things I have tried:
* Hard reset on phone from recovery (plus endless deleting of cache and dalvik)
* Hard reset using Wugfresh toolkit (plus near every other tool on there)
* Hard refresh from recovery mode
* Hard refresh using ADB and deleting user data etc.
* Flash recovery from ADB (also using Wugfresh as per above)
* ADB sideload from recovery of factory images, bootloaders and other ROM's
* Lock/unlock/root/unroot - using ADB commands as well as Wugfresh and other toolkits
* Delete data, system, cache
It seems like the Nexus 7 going into read only mode? Erasing /data and everything else in recovery has no effect and also when trying to overwrite the bootloader I get "writing 'bootloader'... FAILED (remote: (InvalidState))" using Wugfresh toolkit as per below. The device is still running JWR66Y.
I'm totally stuck now as to how I get my Nexus 7 back again! I have seen other people having issues with the JWR66Y bootloader (http://forum.xda-developers.com/showthread.php?t=1907796) but have tried all the workarounds and can't seem to find a way to overwrite the bootloader...

Groundhog Day
Hi there
I too have the same problem.
Whatever I do it is Groundhog Day... Seems to be Read-Only.
I have given up & consider it to be a hardware issue. Ordered another motherboard for mine.

A month or so ago my Nexus 7 (2012) started rebooting itself after a minute or so of turning on - I think this may have been during OTA upgrade from JWR66Y to new release. I tried to fix this by clearing app data and booting into CWM recovery and deleting cache and dalvik cache but the problem persisted. So I decided to reset the Nexus 7 back to factory image and have tried every means of doing so but every time I keep getting back to my original data and the app crashes and reboot continues. I have never had any issues connecting to the device on USB and ADB so this is not a driver issue. Things I have tried:
* Hard reset on phone from recovery (plus endless deleting of cache and dalvik)
* Hard reset using Wugfresh toolkit (plus near every other tool on there)
* Hard refresh from recovery mode
* Hard refresh using ADB and deleting user data etc.
* Flash recovery from ADB (also using Wugfresh as per above)
* ADB sideload from recovery of factory images, bootloaders and other ROM's
* Lock/unlock/root/unroot - using ADB commands as well as Wugfresh and other toolkits
* Delete data, system, cache
It seems like the Nexus 7 going into read only mode? Erasing /data and everything else in recovery has no effect and also when trying to overwrite the bootloader I get "writing 'bootloader'... FAILED (remote: (InvalidState))" using Wugfresh toolkit as per below. The device is still running JWR66Y.
I'm totally stuck now as to how I get my Nexus 7 back again! I have seen other people having issues with the JWR66Y bootloader (http://forum.xda-developers.com/showthread.php?t=1907796) but have tried all the workarounds and can't seem to find a way to overwrite the bootloader...

Glad to hear I'm not the only one in this loop! I'll be gutted if it turns out to be hardware issue. Just been on ifixit.com to see how difficult it is to replace motherboard - maybe this will be opportunity to upgrade to the new Nexus 7 2013 version.....

No joy for me. Think I've read every forum and tried every single possible command or procedure and after all of them I end up rebooting back into the same login screen and crashing apps. The fact I can't wipe the data with any command makes me think it's pretty much a hardware issue. Now looking to see how feasible it is to swap out CPU/motherboard......

Very frustrating. I'd even contacted Google support as a last ditch effort but as soon as they learned my 1 year warranty had expired they dropped me and sent me Asus' contact info.
I understand warranties but I'm still rather annoyed.

Yeah I tried Google support too but no joy as warranty long gone. As you say can accept that but annoyed that I now have a £200 paperweight that I can spend another £50 on in the hope of fixing but no guarantee.....

Nexus 7 2012 help
It is not a hardware issue as I can use fastboot to write correct boot loader from jrrv version and it says success. I can't wipe system cache or data. It says its erasing or if I use format command it says its formatting but when I boot up the device nothing is wiped. I found another guy in the same boat woth his Alcatel phone. Its obviously is a software glitch. Any one can help me with this.

Hello,
Does any one know the answer to this issue. Please help

me. AtHey all I have same problem after installing omni ROM on my nexus 7 2012. Its version 4.4.2. Please help me

Add another soul to this helpless ship ... My nexus 7 became like this during the night... not erasing anything. Nobody find any help with this?!

Hi there
I too have the same problem.
Has become so during the night while in recharge.
Impossible ... delete ... restore ... wipe ... flash ... anything.

I am glad I am not the only one in this boat.
My N7 started acting up this weekend. Like the OP, I have just about tried everything under the sun in reflashing the kernel, the rom, etc but nothing works.
If anyone has any ideas, please share.
Thanks.

Could you try relocking then unlocking the bootloader? This guarantees a data wipe.

I tried to relock the tablet last night, but it didn't work. I originally tried to do it manually via "fastboot oem lock", and it seemed to work. The "tablet is now locked" message appeared on screen. However, the command line on my desktop froze until I manually rebooted the tablet, which caused a failure message to appear in the DOS window.
I then tried WUG's toolkit. Again, everything on the surface appears to be a success until the tablet reboots. But, the Google screen continues to show the unlock symbol.
It is very weird that fastboot and adb seem to communicate properly and get the correct responses but the actual data on the tablet doesn't change. The only way I can alter any data is when I boot TWRP via WUG (I have CWM on the tablet) and delete folders in the \sdcard folder. Unfortunately, the virtual TWRP app won't connect for ADB sideload and I can't seem to get TWRP to replace CWM on the tablet either.

RIP Nexus 7
If anyone finds a fix for this , thanks in advance.

I've got the same problem - will buy new mobo
Can't unlock the bootloader the normal way (fastboot oem-unlock). Don't have the "blobs", so nvflash won't work. Can't believe there isn't a way to completely "nuke and pave" so to speak. I might hold out for the Nexus 9, or just get a new mobo from ebay.

Hey I am in the same boat with nexus 7 2012 WiFi. Can't even flash factory image back. Unable to install any new apps. When I reboot any new apps installed are wiped out and tablet returns to old state with same data

Crap, how did I miss this tread before I started a new one .
Add me to the list, I have the same issue:

I am pretty sure this one is a doozy, or that I am missing something very simple... you know, one or the other
First the facts: 2012 Wifi Nexus 7 running 5.0, stock rom, unlocked bootloader - nothing fancy about it.
Some background: I've been having a constant reboot issue for a while now... not quite a bootloop, as it allows me to enter my screenlock and even open the settings menu before suddenly rebooting again (at random intervals). Any changes I make in that time are lost upon reboot and it takes me right back to my 5.0 lockscreen (even if I disabled it the last time it was booted) - Same thing happens if I uninstall any apps, they are there when I reboot again.
I am able to see my device in both fastboot and recovery.
I've tried a factory reset from the Settings menu - no go, right back to my 5.0 lockscreen.
I've tried to reset from recovery - no go, right back to my 5.0 lockscreen.
I reflashed the image from the bootloader - no go, right back to my 5.0 lockscreen.
I flashed 4.4.4 - no go, right back to my 5.0 lockscreen.
I flashed 4.4.2 - no go, right back to my 5.0 lockscreen.
I flashed 5.0.2 and the same thing happened - no go, right back to my 5.0 lockscreen. (I was able to check About Tablet... no changes there either)
same thing with Safe Mode- no go, right back to my 5.0 lockscreen.
Wug's toolkit failed on me when I tried that, after the bootloader and boot image failed I got an out of memory error. (tried a couple versions here, Jelly bean actually forced fastboot to close on me)
I did a Remote Erase Request from Android Device Manager, it did not work either.
This is sounding like a hardware issue, right? Anything I can do about that if so?

I have the same problem.
Asus Service Support in Spain (cygitsolutions.com) considers it is a hardware issue. They want a motherboard replacement for 190€ (like a new one).

my google nexus can't wipe data/factory reset,,,is there any solution???it is restarting again and again,,,,

Free Beer to anyone who can help!!!

Free Beer* for anyone who can help!
I have a serious problem with my nexus 7 (2012) which I have been researching and working on for many months now to no avail. For this reason I am offering a free beer to anyone who can help (t's&c's apply)!
Background:
The device has stock 4.2.2 rooted installed along with Multirom which has CM10, paranoid android and Ubuntu (desktop).
All this ran fine for a while. I then noticed that if I made any change to the stock rom, update an app, download an app, change the wallpaper, download a file to any part of the filesystem... that when I rebooted the tablet that change would not be there... The wallpaper would be back as it was or the file simply didn't exist! It was as if the filesystem was mounted as non - persistent.
So I tried the other rooms on the tablet and realised they would not boot. All except Ubuntu which was working fine however doesn't mount the internal storage so I couldn't test any further.
I attempted to re flash back to stock. Using flashboot I cleared the cache, system, user data etc and had no errors and then flashed the stock rom. After rebooting my old system appeared to my surprise.
I have tried since then to re flash everything. Recovery won't update (currently TWRP) and the only time I get any error message is when trying to re flash the bootloader which is currently 4.18, everything seems to go well and then "signature match" appears on the tablet screen and it hangs leaving an error in the fastboot terminal reading "Remote: ()"
If anyone can help me fix this issue then the beer is yours... The only stipulation is you have to be in Ireland to claim it but what better excuse for a holiday
Thanks in advance.

Booting up your freshly flashed stock device...
--------------------------------------------------------------
Wait for your device to finish booting up...
- It may appear to be boot looping; just wait...
- It could take 5-10 minutes; please be patient...
When its finally booted back up, please remember
to re-enable USB debugging if you plan on using
the toolkit to perform other operations.
NOTE: If this process was too quick and your device
is still in bootloader mode, then flashing stock may
have failed or been incomplete. Simply check the
log above: if you notice it skipped steps because it
didn't meet certain requirements, like the bootloader
or baseband version, then consider enabling 'Force Flash'
mode in the toolkits options menu and trying the
'Flash Stock + Unroot' processs again. Cheers.

I used the same stock rom I am using so I ddn't have to flash the bootloader which is an issue (see above).
I can't see any errors in that terminal, everything looks fine but when the tablet reboots it has not changed a single thing!! Multirom is still there as it was and my old rom and userdata and everything down to the crappy wallpaper I put on 8 months ago is still there!!
Can anyone PLEASE HELP!!!

So what do you want to do? Get rid of the multirom and get back to stock? If so do you care about your data?

Exactly that! Don't care about data, just want a stock working image.

I'm having the exact same issue. Tablet reboots after 5 seconds after the lock screen loads so I thought I'd erase user data and re flash the rom. Except that it doesn't actually flash, or erase anything. I've tried toolkits and fastboot. And the log always says the flash has performed successfully but it always reboots to the same old rom, wallpaper, all data still intact.
It's almost like the partitions are write protected and won't allow any data changes.
If anyone can help with this issue, I'll double the free beer offer!

Can I just ask, are you using multirom aswell? Your the only other person I've heard of with the problem, we should go more notes and try and narrow this down.

No multi-rom. I've found about a half dozen other threads with people experiencing the same thing. It's rare, but it's not just me. Being completely unable to wipe data has me thinking there might be a hardware issue at play.
I'll post links to some of the other threads. Thanks for offering to help. I'm willing to try anything at this point.

Nexus 10: Stuck in Reboot, Tried Flashing Stock ROM With Error

Infinite reboot problem
I need help, my nexus has been continously rebooting by itself. It starts, goes to my homescreen for a few seconds and reboots. I can boot in the bootloader and have tried to do a factory reset, but it just stays a long time in formatting data. After waiting a complete day I decided to stop the process and start again my tablet. It just went to my home screen and again it kept rebooting. It didn't wipe anything.
Next I tried to fastboot flash a stock image, it never gave me any kind of error. My tablet rebooted, but it just went to my home screen, and clearly the image wasn't installed. And again it started the rebooting process.

Hello, did you try to boot on a custom recovery ?
fastboot boot recovery x.img will work.
From there you might try formatting / installing a custom rom.

Yeah, I tried to do a factory reset with twrp, but it didn't work. It stays a long time in formatting cache using make_ext4fs function and doesn't make any progress. I left it like that for 6 hours after I decided to finish the process. It started again, went to my homescreen and kept rebooting.

What is the output of " adb shell dmesg" when you are inside the recovery mode ?

Seems that most likey your eMMC is dead.

You could try formatting with f2fs but fi you already tried unlock/lock I don't think it will helpas it erase the whole storage.

Thanks a lot for your help, I'm going to send it under warranty and see if they can fix it. I hope they don't reject it because the bootloader is unlocked.

PIT files
My nexus 10 has the boot loop problem and I think I have been left with the only option of Re-Partition but I need the PIT file. Can anybody help or provide this file?
I have tried everything else (fastboot, adb, temporary custom recoveries, Nexus Root Toolkit) with no success.
