Sounds like issue with disk quota management
Use this instead of using no-verity zip to disable disk quota.

You will have to re-name the file to add 'quota ' to the file name.

Can't decrypt Galaxy Nexus after OTA

Just applied the 4.0.2 OTA update to my GSM Galaxy Nexus and after the reboot, even though i type in the correct password, my phone wont decrypt.
I read on android forums people with the 4.0.3 OTA having the same problems.
How can i reset my phone? How does Odin work? Somehow i am stuck at the screen with the android and his open chest
ok i got odin workin, needed to install the android sdk, wiping my phone now
Please note: YOU WILL LOSE ALL DATA
everything seems ok, i got into odin mode like this:
-connect your GN with usb to your computer
-start with power + volume down
-use volume up / down to select recovery mode
-confirm by pressing power
-you will see an android with a triangle
-press power and volume
-select factory reset
-confirm with power
-reboot
this worked for me only after i installed the android sdk, before that somehow i was stuck at the android with his chest open and couldnt select anything because somehow my device wasnt recognized
hope this helps
This also caught me out. Not happy.
Method I used (posted on OTA thread) worked without installing SDK:
Power off
Hold Volume + , volume - and power
You should get a green android image with the body opened with "Start" on the screen
Press Down till you get to recovery mode
Press power
Phone will reboot
You will then get same image of android (smaller) with red warning triangle
Wait a minute or two and then press volume + and power (not sure exactly what I did for this maybe it's just waiting)
Use volume down to select wipe data/factory reset and hit power
Select Yes - delete all user data and hit power
Once done select reboot system now and hit power
You are now back to zero and can start again.
Hi I have roote, and installed cwm, I the applied the encryption proces, now I want to flash a ROM (revert to stock) thru cwm, it says can't mount SD card. I try do a factory reset through cwm but also says can't mount....
Any tips on how to remove the encryption?

The only way to decrypt an encrypted phone is using fastboot. Fastboot is a developer tool that runs on your computer. You need to download the full Google factory image or a full rom, and flash all of the files to your phone using fastboot.
CWM and other recovery software will not be able to factory reset the device.

This is not entirely true. You should be able to use TWRP 2.2.0. As well, have a look through this thread.

[Q] Root Help Please SM T210R

I have CWM installed on my Tab 7 and when I go to install the universal root that I copied and pasted into the external SD I get two messages saying in red
"failed to verify whole file signature"
and one saying in red
"failed file signature"
I downloaded the universal zipped root file twice and its the same thing over and over. I have USB de bugging on too. Any help would be greatly appreciated. I have been up all night and been at it for hours trying to fix this issue.

Thank you for the timely response. Unfortunately I just noticed in the background in CWM that my droid man has a red triangle with ! point inside him. The options given to me are as follows...
Reboot system now
Apply update from ADB
Apply uopdate from Ext. Storage
Wipe data/factory reset
Wipe cache partition
Apply update from cache
Which of these options should I use if any and or should I flash CWM again on Odin in order to get the screen you are speaking about?
If I do need to flash again what are the correct steps to clear what CWM is already in place? Thank you again for all of your help. I am a noob that rooted my SIII a while back and obviously it is a little different with the Tab 7.0.

Ok I did that and got a pass on Odin. Now my screen is still in Odin mode with a green droid in the middle and under that it says in white letters Downloading....Under that it says Do not turn off target!! in green letters. How do I properly restart? In CWM as normal? (Hold POWER, Volume UP, and the HOME button all at the same time. When you see the Samsung Logo, let go of the POWER button, but keep holding the Volume UP and HOME until you see the recovery screen). Thanks...

Update...Just re read this
--Auto Reboot can be un-checked if CWM doesn't flash correctly on your device. Some have reported that un-checking Auto Reboot fixes this issue. If you un-check Auto Reboot, you will need to reboot the device yourself (refer back to step 10).
Trying now fingers crossed!!!

Help! N7 stucked at loading screen while attempting to root

Hi all,
I tried to root my Nexus 7 according to this youtube link
http://www.youtube.com/watch?v=X1cD-JXRGX8
During the step to install" super SU", i copied the the "unzipped" version of the file into the device, and couldn't install it as per video.
So i tried restating the device to try to copy the right file to the device, but now it just stucked at the loading screen (circle & square alternating, not the X screen) and i couldn't power it off too.
What should i do? Help please! Thanks!

Is it still recognised by the computer?
As in, if you plug it in with USB does it appear on your device manager?
Anyway, I would recommend using Wug's Toolkit (http://forum.xda-developers.com/showthread.php?t=2389107) to sort you out.
It's pretty straight forward so you should be able to fix it easly.

No it's not recognized by my PC too. So the toolkit won't be useful too i presume?
Any other options? Just wait it out till the battery is dead?

Long press the power button and that will make it reboot, as soon as the screen turns OFF, hold down the volume down button and it will boot into the bootloader, use the volume button to select recovery, press the start button to go into recovery. In recovery (TWRP) click on wipe then do a factory reset. If it is off, press and hold volume down and power button together and that will get you to the bootloader screen.

This whole rooting process confuse me. So you're saying after doing this, just start over the rooting process as per youtube link again or continue the step where i did wrong?
P/S is it easier to root using that rootkit as per post above?

You're two thirds of the way there. You supposedly have the bootloader unlocked, you can see that when it boots up at the "Google" screen the lock will be unlocked, It will also say unlocked in the bootloader screen. And you should have TWRP installed if you tried to flash supersu. So.. at this point, you need to flash the supersu "zip" in TWRP. Before you start making any changes I would recommend making a backup in TWRP.

What you are using is part of the android sdk (adb/fastboot), the platform-tools folder with the usb drivers moved into it, not really a toolkit. I've never used a toolkit so I can't say a lot about them, I have the complete sdk installed, you were using part of it. Were you able to boot into recovery and do a factory reset?
You should not have followed that guide.
1st: Go to here: http://forum.xda-developers.com/showthread.php?t=1538053. Download the zip. DO NOT UNZIP.
2nd: Make sure that ADB is set up on your computer. To download, go to https://developer.android.com/sdk/index.html. Follow the instructions to install. Open the SDK (should be in C\development\adt-bundle-windows-x86_64-20131030\, or whereever you installed, it is an execultable file. It should have a little green android logo next to it, and it is called "SDK Manager". It will take a couple seconds to open. Once it has opened, install "Android SDK Platform-tools".
3rd: Move the Super SU zip into the C\development\adt-bundle-windows-x86_64-20131030\sdk\platform-tools, or wherever you installed the platform-tools. It should be inside the SDK folder. Just paste the zip there.
4th: Boot your Nexus 7 into recovery. Push and hold the power button and volume down button at the same time and boot into the bootloader.
5th: Boot into recovery. Do so by pressing the power button for a while, and eventually it will shut off, as mentioned above.
6th: Press and hold power button and volume down to boot into bootloader. Once in the bootloader, push the volume down button until recovery is selected.
7th: Boot into recovery by pressing the power button.
8th: In recovery, wipe the cache and dalvik under the advanced wipe in the wipe menu. Go back and click install. Click "apply from sideload", or something like that, I forgot the exact wording. Connect your tablet to your computer through a USB cable.
9th: Go back to your computer. Go to C\development\adt-bundle-windows-x86_64-20131030\sdk\ or wherever you installed the sdk. Press shift, and then right click on the folder that says "platform-tools". In the menu, click "open command window here".
10th: Copy the exact name of the supersu zip file in the platform-tools folder.
11th: In the command window type: adb sideload UPDATE-SuperSU-v1.86.zip
12th: Press enter. The name of the super su file may not be exactly that, but similar to it.
13: Reboot your tablet.
I don't know if you are a noob, or very experienced, so I made this as noob-friendly as posisble, sorry if I offended you in any way. Here are some pictures.
I did manage to boot into bootloader screen 7 the option to start, but same thing happen, it still stucked at the "4 colors" circle screen. Problem is guys i couldn't get the PC to recognise my tablet even in the bootloader screen. What should i do now?

Ok i can boot to recovery mode and get to TWRP. But as my post above the superSU is not in zipped form, what should i do then? And i couldn't copy the zipped verison into the tablet as my PC won't recognise the tablet. Do i choose wipe to start all over again from scratch? (assuming that's what wipe will do?) or browse into subfolder of superSU "i.e. app, bin, etc, xbi" and install form there manually? Dam im confused without knowing any basic of rooting...I thnk you're the closest to understanding where i am now, please help! Thanks!
ok guys i think my N7 got some serious problem!!
Now it would just stucked on the Google screen and won't even go to the recovery mode!!!

Try and do a factory reset. Just remember a factory reset is not a restore and it will not put your device back to the way it was before you tried to root. A factory reset will wipe the cache and data, not the system. Any changes to the system, kernel or recovery that you made will still be there after a factory reset. Go ahead and dot a reset and let's see if that will get your N7 to boot up. And we can go from there.

Anyway... getting supersu installed is a non-issue if you can't get it to boot up. When you were trying to download supersu what you were looking for was the installable zip at Chainfires thread."CWM / TWRP / MobileODIN installable ZIP: http://download.chainfire.eu/supersu."

Any manual hardware reset option on N7?
If a factory reset didn't clear it up you might be able to get away with just flashing the system image. Long pressing won't make it reboot?
I'll tell you how the tablet is right now, and hopefully you have some ideas where to go from here.
Atm, when i turn on and off the tablet.
but when i turn it on, it will go straight to the google screen with lock image at the bottom, then it will just stuck there
I tried going to recovery mode, and it won't come up with TWRP , and after a black screen, it will go back to boot screen
Tried "restart bootloader", did nothing too, just gone back original boot screen .
So now what? Gosh did i just break my brand new N7?

you may want to flash your phone back. so this consist of
1) read up how to access to Temp CWM
2) download and transfer the full rom to your SD card
3) do a wipe all partition and go to advanced setting, wipe cache
4) install zip and choose from external SD, point to that .zip file for the full rom and apply.
5) installation may take 10min or so do not switch it off. after installation you are good as new.
I believe this should solve your problem, normal if things get bricked is due to config file error could be [syntax, corrupted, missing, setting].
Flashing should solve mostly of it unless the file that you previously accessed require root and cwm does not give permission to the file. that is a permanent bricking.
As always, newbie should not try tweaking permission required files, you end up having bricking the device as there might be no solution to recover it due to access rights. ALWAYS have a back up file so you can at least copy the file back and chmod it.

my problem right now is my pc wont detect my phone. Ive already installed the drivers.
Same thing happened to me when I tried flashing the OTA update with my phone being rooted. You have get into recovery mode on the phone and then use ADB to put the original image back to the device to get it back to stock so it will reboot. It worked for me

here is the stock firmware.
https://www.asus.com/Phones/ZenFone_2_ZE551ML/HelpDesk_Download/
its fine if your phone does not talk to your PC now. copy the firmware to your SD card via other means. [card reader etc]
then try my method of flashing it back to original state, you stated that adb dont work, have you tried the temp CWM method yet?
the main goal is to wipe dalvik cache under advanced menu in CWM, and cache partition and all hard reset.
then you flash back your original file.
hope it works for you.

ive read about the temp cmw method and i cant figure out how to go about it. it says on the instruction that you need to turn on phone before running the cai_dat_CWM. how am i going to do this as my phone will only boot to the asus logo? thanks
just figured it out. I need to boot in fastboot so the phone will get recognized. However, the latest build available on the asus website is still 2.17.40.12. I already have the 2.18.40.12 version. The 2.17 firmware can't overwrite the newer build in temp CWM recovery. Anybody knows where i can download the full rom? Z00A-WW-2.18.40.12?

here is the link for stock but pre-rooted img for latest 2.18.40.12 firmware,,make sure to download Z00A firmware if you have ZE551ML device.. and if I was not mistaken, you may choose to FULL UNROOT in SuperSU apps to go back to stock rom..

you may want to flash your phone back. so this consist of
1) read up how to access to Temp CWM
2) download and transfer the full rom to your SD card
3) do a wipe all partition and go to advanced setting, wipe cache
4) install zip and choose from external SD, point to that .zip file for the full rom and apply.
5) installation may take 10min or so do not switch it off. after installation you are good as new.
I believe this should solve your problem, normal if things get bricked is due to config file error could be [syntax, corrupted, missing, setting].
Flashing should solve mostly of it unless the file that you previously accessed require root and cwm does not give permission to the file. that is a permanent bricking.
As always, newbie should not try tweaking permission required files, you end up having bricking the device as there might be no solution to recover it due to access rights. ALWAYS have a back up file so you can at least copy the file back and chmod it.

Same thing happened to me when I tried flashing the OTA update with my phone being rooted. You have get into recovery mode on the phone and then use ADB to put the original image back to the device to get it back to stock so it will reboot. It worked for me

I already tried it like 20 or more times. The ASUS logo still shown for like 10 seconds and died and came back again (ASUS logo). When I tried to connect it with my laptop, the computer won't recognize the device.

I will try to tell you step by step:
1. Press Power Button + Volume Button

then press Power Button (From Recovery Mode), it restart.
2. Then after Restart it shows you (Mostly) Sleeping Android Screen with Error text, then Press First Volume Up Button, and Press Power Button (Power button for a second or two then leave it, IF YOU PRESS MORE TIME, IT WILL RESTART THE PHONE).
3. You can now see the Recovery Menu with Normally appear in other phones also - Reset, Restart, Etc Option.
Hope you will now able to reset your phone...

Trying to get root android lollipop leads to bootloop

I flashed lollipop on my tablet. I am trying to get root access but I get bootloop. Crash occurs after installing SuperSU. I tried to install in CWM and TWRP, wipe or not wipe, install SuperSU before install patched boot, but bootloop stays.
What tablet do you have?

Same story with SM-J200G. Installed latest 5.1.1 firmware. Flashed TWRP also. But when i flash Supersu 2.46 0r 2.52 beta, bootloops start....! Really annoying since i cant root this device with any methods.
Factory Reset device in Menu/Backup
Reboot
Turn off
Go in Download mode power+ volume down
Fire up Odin

Reboot
Set everything up
Place boot.img extracted and rename from the patched file post here in post 1 to the root of your internal sdcard
Power off
Go in Download mode power+ volume down
Fire up odin
Unthick auto reboot in options
Flash TWRP 2.8.7.0xxx.tar that you have download previously
The device will not reboot
Press power off button until device reboot
Boot should be successful
Power off
Reboot in recovery press power+ volume up until screen flash briefly, release power and volume up after
Wait until unit boot in recovery, take out your pen
Select install
Select SD card and select the boot.img previously copied here
Reboot but avoid fixing Supersu if requested by TWRP (Square at the center of the screen before rebooting)
You should be able to reboot with no loop
Copy SuperSU 2.52.zip to root of your SD card
Power off
Reboot in recovery
install
Look with the pen for SuperSU.zip in root of SD Card
Flash it
Reboot
Same here if requested to fix SuperSu don't do it
You should be able to have a root system working with no boot loop

What's your device? If it's the SM J200 you mentioned in your post, the attached files won't work.
You can try making a patched boot image from your firmware. Steps are in OP.

No success too.
Thanks, everyone! I have installed boot. The problem was that initially installed the wrong boot. I found it somewhere in the thread of the installation root, but not in the header.
