Encryption unsuccessful help

[bcwest]

Hello,

I turned on my Xoom to see "Encryption Unsuccessful" tonight. If i boot into stock recovery and try to factory reset, it cannot mount Cache. If I plug the device into my computer, fastboot can find it but ADB cannot. I have the proper drivers installed. I can't get into my tablet to turn on USB debugging. I just bought an OTG cable to try to fix it, but cannot find the update.zip file that I need. If i try to fastboot oem unlock, it fails. I've tried everything I can find, I've done hours worth of playing/trial and error to no avail. Any help would be fantastic. Truly at a stand still. Please ask with any specifics needed to assist me.

Is it possible to flash to CWM recovery without being able to boot/find it in ADB?

Thank you,
Bradon

>.<

Nearly to the point of offering some sort of payment for assisting me. I'd rather not ship it out, but more than glad to work something out paypal or giftcard wise. This tablet is the only thing keeping my wife entertained, and another tablet is not in the budget.

Probably you will lose all data on it ... Why u wanted to encrypt u device ...
I did it too but it was missunderstanding specialy when flashing a lot .

Alright so...
I've used fast boot flash user data, system, recovery and boot. Those are all successful, but if I reboot.. Nothing changes.
I've loaded many zips onto a flash drive with an otg cable, boot into the stock recovery and try to update, unable to verify signature.
Adv will not find the device, reinstalled drivers many times
Rsd will not find the device
Factory reset fails, cannot mount cache and about 10 other cache/recovery errors
Fast boot OEM unlock fails, unable to write a certain 3 letter file

I'm at work right now, so I can post specifics/pics later.

I didn't try to encrypt it, it seemed like a virus that my wife got. She clicks on advertisements, downloads sketchy files/apps.

It is unrooted, stock recovery.

20+ hours of research and trial.. No success.

Use 2 method.

You have to unlock bootloader

And u do not need any special otg cabel - use stock xoom from package. OTG is for host-usb.

Anyway u will have to do it with fastboot , probably /cache partialy encrypted.

Alright, I just followed the CWM recovery guide.

First off, ADB does not find my device, meaning I cannot reboot into the bootloader. I can flash the recovery only after flashing userdata for some reason. After flashing, it says complete though when I reboot nothing changes. The other 2 links, first one I can't use because adb doesn't find my device, and the 2nd one.. I don't think xoom has a "download mode".

Thanks

Ok, so when u push down button in booting u have only recovery ?
U should have fastboot too ... try to press up vol 1 s after booting, then connect to pc, and check in device manager rmb on "My pc"
And ? .... This must working ... Use fastboot.exe in cmd ( in windows 7 ) on Administrator User.

Also, when I first boot up recovery I get

E: failed to mount /cache (invalid argument.)
E: Can't mount /cache/recovery/command
E: Failed to mount /cache (invalid argument)
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:failed to mount /cache (invalid argument)
E:can't mount /cache/recovery/last_log

E:can't mount /cache/recovery/last_install

If i try to factory reset or clear the cache, I get the same message.

U do not understand what u reading, u cant do this from recovery ...

U have partialy crypted storage ... its normal!

1. download fastboot on windows
2. install drivers from

1) Get the Motorola USB drivers MOTODEV > Documentation & Tools > USB Drivers (you need to sign up on their but maybe you can google this and find it as well)

2) Get the Android SDK Android SDK | Android Developers (you only really need the fastboot executable file for your host OS)

3. run fastboot protocol on xoom press down vol "find fastboot" if not press top vol in booting - should fastboot protocol ... in output
4. Use fastboot.exe from android sdk - run in in cmd ( Run ad Administrator , right click on cmd)
4. unlock bootloader
5. flash rom boot recovery in *.img format!

This must working...

When I connect it to my PC in fastboot mode, it comes up as "Mot Single ADB Interface"

Is it bad ? - now when u show up "fastboot protocol ... " on xoom run fastboot from android sdk .

unplug mmc card from xoom and try again, where did u get files ... system.img ,recovery.img,boot.img ?

 

[bcwest]

I've tried with both the mSD card in, and out. I got the boot/system/recovery/userdata from the stock image post from XDA.

 

[gucio1200]

ok, I didnt tryed this with stock rom, try to change recovery with http://forum.xda-developers.com/showthread.php?t=1074979
reboot and try to get to new recovery.
do this:
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img <- from http://forum.xda-developers.com/showthread.php?t=1074979
fastboot flash userdata userdata.img
fastboot erase cache
fastboot erase userdata
fastboot reboot

Which model of xoom u have ? Did u restart xoom after flashing ? Is there any output ? (without up,down vol )

 

[bcwest]

mx600 is the model that I have.

All of the flashing goes through fine
fastboot erase cache fails instantly (Failed to format PDB)
fastboot erase userdata fails instantly (Failed to format PDB)
fastboot reboot
volume down for recovery to see if CWM changes went through
stock android recovery

 

[bcwest]

If I put my mSD card back into the unit, and try to do it all over again..

Flashes go through fine
Cache fails instantly, same error
Erase userdata causes my cmd to hang up, and the xoom sits at "StorMgr Formatting UDA STATUS: | | |"
5 minutes later, still sitting at that message.

 

[bcwest]

Mx600, I restarted the device after flashing everything, If I let it go past the Dual Core Technology big red M, it boots into android but all that I get is the Encryption Unsuccessful screen. It says push restart, but it does nothing.
