I have two identical xooms. The model number lists as "Xoom". Android version is 4 .1.2 , build JZ054K, kernal version 2.6.39.4-g4e32b94 . I've been trying for days to update at least one of them. I'm using a Linux Mint 17 desktop. No Windows available.
I've tried everything I found on these forums, and nothing has worked. I have 32gb external sd cards in both of them. My first trak was to do it from the SD card but I found that recovery cannot see my SD card. I also tried putting " BigPart" in a directory called downloads, but that didn't help. I also tried loading it onto the internal card. Can't see it either way.
I downloaded the Linux android files and plugged in the USB cable. I could talk to the Xoom, and tell it to reboot the bootlooder into fastboot or recovery, and the Xoom would reboot but lock up at the "loading fastboot" screen. I tried sideloading the BigPart file, but the install would fail on validation. If I try to enter fastboot by rebooting it locks on the loading screen. If I load recovery on boot it appears to come up but It can't see the SD cards or accept the files from the computer (From adb).
One of these Xoom's I gedfied and the other was a google device when I bought it. Both got all of their last bunch of updates thru Google, until Google dropped them. Could the google updates have left something needed out??
As I understand the process getting Big part on the device is the first step. I have all needed files for the upgrade,on my SD cards and on my Linux machine. I just can't use them. Anyone have any ideas? Does anyone know where and what the OS is looking for during that attempted USB update??

Ok after 70 views and no responses, I'm giving up for now. Turn off deleloper options, and letting Google have their way with my Xoom android 4.1.2 . "I think" part of the problem is my Xooms will NOT boot into Fastboot. For what ever reason I do not know. The bootloader is still locked because I can't get to it to unlock it (using my Linux box) I know they can be unlocked because I did it a few years ago with my XP box (long gone). Is JellyBean the end for my Xooms?
