[Q] Xoom "Failed to boot LNX 0x0004"

[hlokk101]

Hi

I have been having this issue with my Xoom for quite some time after I tried to reset it back to stock and followed the instructions I found at a thread which I have lost, but included the instruction to lock the bootloader, which I have since learned is not advisable, and have not been able to fix it after many Google searches for solutions.

Each time I turn my Xoom on it comes up with this message:

So far I have tried solutions from these forum threads:

Failed to boot LNX 0x0004 Startinmg RSD mode 2 Xoom WIFI ONLY MZ604

Failed to boot LNX 0x0004 Startinmg RSD mode 2 Xoom WIFI ONLY MZ604

(Xoom WiFi Only MZ604) failed to boot lnx 0x0004 - starting rsd mode 2

Stuck at Motorola Dual-Core? [Wifi-Only]

Every time I get stuck at the same place: <waiting for device> on my command prompt, while my Xoom sits on this screen:

I have set up fastboot and adb on my pc using the tool I found on this thread:

[TOOL] [WINDOWS] ADB, Fastboot and Drivers - 15 seconds ADB Installer v1.4.2

My Xoom is a wi-fi only EU model (wingray), I do not have the original USB cable that it came with though I do not think that makes a difference. I am at a loss as to how to fix this problem.

Is there anyone with an up to date solution for this issue? Thanks.

what happens when you type "adb devices" ?
the commands for flashing the stock image are as follows (i have a copy, if you need it PM me)


fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock

Fixed!

Thanks for replying

After you questioned what happened when I typed 'adb devices' I had the very belated brainwave of maybe checking that it was correctly set up with one of my other devices (duh! ><). Thus it was I discovered that despite the installer I had used assuring me that it was correctly set up, I found that it wasn't actually correctly set up.

With my Nexus 7 as a test device, and the WugFresh Nexus Toolkit at my disposal I was able to set up ADB so that it worked with my N7. Plugging in my Xoom I found that it was still invisible to my computer, so I Googled for Motorola USB drivers and came up with the Motorola Device Manager which installed it's own ADB driver. Once that does done I was pleased to find that my PC was now able to see my Xoom and I have flashed the stock images I got from the Motorola website and my Xoom has now been fixed!

Thanks for your help and inspiration
