Please Help with Bricked Xoom?

[nomadman]

Hi all,

I've exhausted all my resources in trying to get this tablet to work. It might be hard bricked if that's even possible. Just a little back ground on what happened. The device was running very slow after 3yrs of using wingray (wifi MZ604?) [ROM][4.4.4] OmniROM - Wingray - bigPart. Anyway it's from Verizon and it only has wifi. But as I said, it was running very slow so I figured i'd flash back to stock ROM. The stock ROM flash fine and it was pretty responsive. Then this where everything went to sh!*.. I received an update notification, it updated, rebooted and the tablet is stuck on Dual Core M boot screen. I have tried to restore by flashing OmniROM - Wingray - bigPart and RDS back to stock ROM, both stuck on Dual Core M boot screen.

I spent over 48 man hours reading through the forums on how to unbrick this tablet. Unlocking the botloader and pushing twrp big part and flashing a custom ROM, to using One Click Tool made by XxLordxX to try to get it back to stock and installing Omni ROM. None of which seam to work. It always ends up stuck on Dual Core M boot screen until it runs out of battery charge. There is no way I can get into any type of recovery.

I have access to the following items:

- fastboot
- RDS

I don't have access to the following:

- bootloader
- ADB
- default or custom recovery

If anyone can assist, I would really appreciate it.

Edit: if it helps, this is what i extracted from the device in fastboot

(bootloader) version-bootloader: 1045
(bootloader) product: xoom-cdma
(bootloader) secure: yes
(bootloader) model: MZ600

download twrp img file and use fastboot to upload the recovery? "fastboot flash recovery twrp-3.0.x.x-xxx.img" just gotta find which twrp you want. by the by, I just flashed the files from here and now I am getting a boot screen instead of stuck at bootloader like you ;

Unfortunately any twrp recovery I flash with fastboot doesn't allow me into recovery. Without recovery I can't flash those archives. Very annoying. But thanks for the heads up. I guess the main priority is to get a working recovery.

Change the usb cable. I'm not joking, that might be the problem!
If that doesn't work, use RSD lite to flash the original ROM (the SBF file, you will find it on the internet). Make sure to flash the corresponding SBF to your tablet.

Yea I believe you about the USB cable but unfortunately this was a hand me down and the original cable was lost.

I've tried all the SBF files I can get my hands on and it still gets stuck on the M logo screen and I can't get into recovery mode. I can list all the sbf files I've tried. They are still stored on my NAS.

Hello nomadman,

Check a zip from this thread according to your Xoom model version and area:

https://forum.xda-developers.com/showthread.php?t=1049485

Unzip the file. And do these commands to boot your rom:

fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash userdata userdata.img

Use this method to your own risk. I think it should work, but... I suppose it is your only chance to have stock rom again.

Thanks @Manuallama. I will give this a shot since I don't really have a choice. Before I flash I usually fastboot clear those boot, user, and system. We do this when I get home from work. Cheers
