MZ602 stuck on splash screen
I'm at the end of my rope. No matter what I try, I can't get my MZ602 to work again. If I try to boot normally, I get stuck at the "M" splash screen. If I try to go into recovery mode, I get stuck at "reading ODM fuse 1". Fastboot and RSD modes work. Here's what I've tried:
Flash HLK75D (stock 3.2.2) in fastboot
Flash HLK75D using RSD/SBF method
Flash recovery-Tiamat-R4c-100611-1150-cwm.img in fastboot
Lock / unlock the device
All of these ran successfully, but didn't make a difference. I have a bootloader to try and flash, but, from what I understand, it has to be done in CWM recovery manager, which I can't get into. Is there anything else I can try, or do I have a genuine brick on my hands? Any help would be greatly appreciated.

Welcome to the forum. Glad you decided to join us. What exactly where you doing when this happened?

perhaps your rom/backup is corrupted
is usb debugging enabled? if so, fast boot the stock boot loader image.
instead of trying to restore a root/rom fastboot the original stock build/baseband/bootloader for the lte xoom (you are sure its a verizon 4g lte xoom, right)
or try the jellybean 4.2 version: How To Install Android 4.2.1 Jelly Bean on MZ602 Xoom LTE via Custom Firmware

I got it secondhand with this going on, so I'm not sure how it got to this state.

If I do nothing, it will juts get stuck at the splash screen while RSD Lite asks for a manual reboot.

I fixed it! I downloaded and flashed Everest 1.35 which I found here in the forums. That got me out of the boot loop. Then I flashed CWM recovery in fastboot mode (thanks to Astrix's rookie guide), and put the LTE baseband update as update.zip on my SD card (found that here). I booted into recovery and selected to run the update and followed the prompts. When that rebooted after finishing, I went back into RSD mode and flashed IMM76L (thank you Rive). Though at that point, I'm sure you have the freedom to flash whatever image you like.
