Hey guys,
I'm experiencing a weird problem with a Nexus 10 that was gifted to me. For some reason the Nexus 10 can't receive any updates and reverts to it's last state after a reboot. That probably doesn't make sense so here's an example:
I turn on the Nexus 10. I change the language in the settings. I connect to wireless. I install apps. When I reboot the nexus 10 has no history these changes were made.
Wiping/factory reset from Recovery does nothing. I can select the option but when I turn the tablet back on there is still a completely configured profile with personal data present.
It's currently stuck on 4.2.2. When I try to install the OTA update the installer downloads, the tablet reboots, then no record of the install is seen.
Finally, I've tried to flash Google factory images via ADB and fastboot. But, I can't complete the install because the bootloader doesn't remain unlocked after a reboot so the install never finishes. It seems to me the tablet memory is stuck in a state of read-only.
It seems to me the tablet is stuck on Read-Only somehow... does anyone know what else I can do? I've never experienced this problem before. Most of my research indicates an eMMC problem?
Thanks!

I cannot use the default "Encrypt Phone" option on the settings menu of my Nexus 4. When used, it just reboots the phone and I have done this process over 5 times with no success.
I used the Android Nexus 4 ToolKitv2.0.0 and the recommended root tools and am running obviously 4.2.2.
Any reason why it's doing this? Thanks.

Are you using a custom recovery - TWRP or CWM? You need to be using the stock recovery image to encrypt your phone. The nexus toolkit will allow you to re-flash the stock recovery.
One the stock recovery has been re-flashed, you should be able to encrypt your phone. I had to re-flash stock recovery, reboot the phone, then reflash the stock recovery again.
Once the device has been successfully encrypted using the stock recovery, you can re-flash either the TWRP or CWM as your recovery. TWRP supports reading data from encrypted devices, so it is probably the way to go (not sure if CWM dows now, but it didn't last time I looked).
Does encrypting the phone make a dramatic difference in speed (as in slow down) for the phone or does it mainly affect boot times?
Thanks for the tip about having stock recovery as I also wanted to encrypt phone as well. Would one have to de-encrypt phone then install custom recovery to update a custom Rom (I'm running paranoid android) then flash to stock recovery to encrypt phone again- seems long winded :-\
Just from reading the above post once flashed to stock recovery and then encrypted device, it's okay to flash back to TWRP and still have an encrypted device?
Is there another way to do this when running a custom rom?

I haven't noticed a difference in speed, however technically there will be a little bit of a slowdown.
I'm running stock Android, so I don't know how well it plays with custom ROMs, but you can re-flash a TWRP recovery after encrypting your phone with stock Android on it.
If the custom ROM installation wipes the data partition, it would remove the encryption.
I've tried flashing stock recovery using Nexus 4 Toolkit and recovery is back to stock. However the phone is still just rebooting when I press encrypt device. What am I doing wrong?
For some reason I had to reflash the stock recovery, reboot, then reflash the stock recovery again. No idea why, but it worked for me!

Booted back into stock recovery device is still rebooting itself after hitting the encrypt button, Encryption did not happen.
Found the problem but I can't seem to fix it. Flashing the stock recovery doesn't seem to actually do it. When I boot to recovery when flashed to stock, it just shows the android mascot with an open chest and a warning symbol. Have reflashed many times over 5, and still doesn't work. It seems like I need the actual image recovery file. something like Recovery.img?

The android with a warning symbol is the normal symbol of stock recovery.
However, I wonder, if you could solve the problem? My nexus doesn't want to encrypt itself too. Flashed stock recovery already twice and it just keeps rebooting when I start the encryption process.
Quick update: After trying it several times in a row it finally worked (after the fourth time or so). I have no clue why it didn't work before as I haven't change anything.

Thanks for your perseverance! I spent half a day trying to encrypt my rooted Galaxy S4 with the similar problem as you:
I go into System Settings, click "Encrypt Phone", then I get the green android and the phone just reboots itself as normal.
What worked for me: AIRPLANE MODE.
I was rebooting it time after time with no effect (following your suggestion). Once I turned on the Airplane Mode, the encryption started working.
My Current Setup:
Android 4.2.2 Jelly Bean
Samsung Galaxy S4 Google Edition (GT-I9505g) rooted via CF auto root. + Full disk encryption!
Works perfectly!
Now I can have different passwords for disk encryption (long strong password) and for locker screen (simple)

Old thread, same issue, HTC One w/ OmniROM (m7att). My Nexus 10 did it as well.
The person saying to reflash stock? DOn't listen to that. Doesn't need to be done. Encrypted all my devices w/ TWRP installed.
Airplane mode DID work, though.
I just had this issue with my N4, too. I read on the Google Product Forum that this was because a process prevents from unmounting the /data partition. ("Nexus 5 is not going through encryption process" - can't post link due to being new)
With that in mind, I rebooted into safe mode and then tried again and it worked on the first try (At least it started the encryption process, it's at 10% now)
I had this problem for a looooong time. Thankfully, I seem to have discovered a solution for those still encountering this issue.
Turn off SuperSU (Settings -> More -> Application manager -> All -> SuperSU -> Turn Off)
Reboot into Safe Mode (How to)
Run encryption (Settings -> More -> Security -> Encrypt Device)
Turn on SuperSU after complete (Settings -> More - > Application manager -> Turned Off -> SuperSU -> Turn On)
So as of today, the WiFi on my family's Nexus 7 tablet no longer wants to enable. Upon doing a factory reset, we found we could no longer get past the "Select a network" screen. It just got stuck on the message "Turning on wifi". There was no skip button as there would be usually and nothing else could be pressed. I suspect a hardware issue, because I've tried many solutions and the closest I've come is just making the device work again. It was unrooted at the time of the issue. When recovery was accessed we were met with a "No command" message.
So the first thing I did was get to work on re-flashing the device. I started back with the original OS from Google's stock ROMs. Fastboot worked great, but I was still facing the same problem on first run of the device. The wifi simply would not enable. After this, however, the recovery menu seemed to have fixed itself. Through this I did a reset process as well...with no results.
The last thing I tried, which restored basic functionality to the device, was installing the Paranoid Android custom ROM. At this point, you could access regular apps and other things. I reinstalled the Gapps and the device was back to normal, with the exception of the wifi. The wifi is a big reason we use the tablet. It would be preferable to find a fix, as we would rather not have to replace something that only has one problem.
As of now, the device is rooted, with superuser on Paranoid Android 4.4.2.
Anyways, I really hope there's a solution to this. It's a great tablet.
Hi guys,
I have searched around the forums and still unsure, weary of what to do. I got my nexus when they first came out. I used it for a while and eventually unlocked it so that i could get certain apps that needed root access. I dont think i flashed a custom rom on it though. I havnt updated android to 4.4 yet. Its been a long time since i updated anything. Hence the start of my dilemma. I went to backup my tablet. It told me SuperUser or the bootloader needed to be updated. So im like oh fine update. Tablet then restarts brings me to my boot screen and says downloading target do not turn off. Its been stuck like this and nothing happens. I held down the power and rocker buttons and got back to boot option screen. Here's where im lost and dont remember what to do. I have tried start, recovermode, restartbootloader, and nothing seems to work. They all bring me back to the dead little android guy
Here's the device info.
product name: manta
variant: wifi
h/w version 8
bootloader version: mantam03
carrier info: none
serial: ****
lock state: unlocked
reboot mode flag: recovery
I slightly recall when i first unlocked it using twrp or clockworkmod? I could be wrong. Either way i no longer have the rootkit nor the computer i originally used to unlock it. What software do i need to install to get me back up and running. I was worried i may brick it if i installed the wrong version kit. That maybe newer version wouldn't work with my n10 because it was running an old version. Any advice would be much appreciated.

Considering that you have not used the N10 in a very long time your user data may not be all that important so here are some options.
1) You could flash the factory image for Android 5 which will wipe out your user data but give you a clean system including stock recovery.
2) You could flash the factory image for Android 5 but first you need to change the "flash-all".(bat,sh) script by removing the "-w" option which will prevent your userdata from being wiped. That takes some knowledge to edit the script but all you need is a simple text editor.
After either of those options you can root and replace your recovery. Root before you change your recovery or you will run into an issue due to specific changes in Android 5.

I'm having similar issues! When trying to install lollipop over sideload it always errors and states not enough space.
I've formated all the data so I'm at a loss.
Any ideas to install lollipop?

I'm concerned I've bricked the device. To be honest I'd be happy just to get kitkat back!
When the device powers up it automatically goes into a "no command" bootloop. With the android on its side with an exclamation point sign coming out.
Holding power and the volume it then goes to the android recovery where I have four options: reboot, apply update from adb, factory reset, wipe cache.
When in command, typing adb devices shows my device.
Using adb sideload I've tried to update, but I always get the error "creating parent of system/app/KoreanIME/KoreanIME.apk failed. error no space left on device
E:Error in /tmp/update.zip
status 7 installation aborted"
So I downloaded the kitkat image and tried to run the script "flash all". But then the command screen just says "waiting for device"
After all that failed, I tried to hold power and the volume button when it restarts. That takes me to the odin screen, where it just states "downloading, do not remove target" The volume buttons do nothing. pressing the power button just reboots.
Any help would be much appreciated!
I have the same issue. There does not seem to be a way to install any (old) version of android. All I get is the same error message "creating parent of system/app/KoreanIME/KoreanIME.apk failed. error no space left on device
E:Error in /tmp/update.zip status 7 installation aborted"
I did not root my device nor did I install a custom rom. I just started installing the OTA update and that's when the tablet got stuck in the boot loop thingy.
I also searched the internet and all I found were similar instructions on how to install factory images etc. using adb sideload.... as I mentioned, following those instructions lead to the error message.
I can' believe this.
Thanks for your help
I also have similar issue. I had non rooted Kitkat 4.4.4 installed on N10. I received update intimation to Lollipop hence downloaded the update. While installing, message regarding error came followed with message "No command" . Now nothing is done further. Even tablet is not getting power off. Periodically screen displaying Google is coming followed with message "No command" I just checked. I can enter in to download and recovery. I now downloaded also Lollipop update for manual updating.
While connecting to PC, it starts searching for driver and after sometime message flashed "Driver not installed successfully" might be due to non detection of MTP. In such case if I try to maually install then ADB also is not recognising the connected device. As novice even I do not know to install ADB sideloaded.
Can you suggest how best I can revive N10?
Regards,
Guys,
I also had the exact problem. What finally worked for is to flash custom recovery (TWRP latest version) with "fastboot flash recovery <recovery.img>" command.
Then from the recovery I installed custom ROM (http://forum.xda-developers.com/showthread.php?t=1998585), as the official ROM also failed.
Hope it will help someone.
Shleim, this seems to just have worked out fine. Many thanks for your help!
I'm still kinda wondering why it wouldn't work with the official ROM. In any case, this is by far better than having a bricked tablet and at least now I know it still works.
Awesome, thanks for this tip!!!

Hi,
I recently tried to update my stock encyrpted Nexus 4 using the OTA Lollipop update. Now when I try to start the phone I can get past the decryption unlock screen as usual, but after that it gets perpetually stuck in the spinning circles sequence. Unfortunately, I have not backed up my data and would like to retrieve it if possible (I thought the backup to cloud feature was enabled, but I guess it wasn't...). I've tried pushing the official Lollipop update using adb sideload; everything seems to work fine (it unpacks and installs without any errors), but when I reboot the phone I still have the exact same problem as before.
Can anyone think of anything that I can do to recover my files? I'm holding out hope that my photos are still on the phone and can be recovered somehow.
Thanks!
I i had to reflash the firmware the correct one TB-X104F_S000024_180930_ROW_DCC. Anyway it wasn't booting at all before i flashed. Now it boots, shows the logo etc and constantly says Encryption unsuccessful!, so i reset it and factory reset it but nothing changes.
I have no idea where else to go, bootloader is locked and all i can do is flash the firmware. Would there be a way to remove this from the files within the firmware?. It seems like android is there in the background but i can't get away from that encryption unsuccessful screen!
Sorry if none of this makes sense.
Yo. I got the same tablet bro. Been trying to figure out a custom recovery for her. A stock ROM would be great to have and I haven't been able to find one anywhere. Might I inquire as to where you found yours? It would be a huge relief to know I can fix it if I break it lol.

If you download the Lenovo MOTO smart assistant from Lenovo support it has a resque option. I also used that to root my tb-x104f. It downloads the original everything and if you take the boot image from the file it downloads and replace it in one that has been modified from magisk it will rescue it and you will have root also thatd what I did with mine
same problem here, reflashed with stock rom. and not resloved

Did you fix this issue?
I am having the same problem.
Thanks
Same problem here (my error reads "Decryption unsuccesful", but I think it's the same as yours).
After a few tries, I believe that it is a problem with the internet connection. After the factory reset, if I skip the wifi connection step, it starts normally. And it is completely usable. I can load pdf documents or apks by the usb from a computer and it runs correctly. But whenever I try to set the wifi connection, it updates something and it causes the tablet that the next time I turn it off, I find the error on the picture when turning on. It asks for a password and no matter which password you enter, then it delivers this message.
In resume, right now it is a completely functional tablet if you NEVER connect it to the internet and load anything you need via usb or bluetooth.
I tried to reset it with Lenovo Smart Assistant, but the result is the same.
I am looking for custom roms to try if it's something about the stock rom, but I haven't found any. Can anyone reccomend me a rom for Lenovo E10 X104F 2GB?
Solution: (Worked for me)
Format Data as F2FS in TWRP. (Advanced Wipe)
Then reboot and wait.
