UPDATE 11/14/12 - Updated OP with SLS's device detection code fixes.
Update 2: Fixed bug in device detection loop causing freeze at "Waking Device"
JET - The Jewel/Evita Tool "kit."
This all started as a downgrade script for the Jewel. You can follow the original JET thread in the EVO 4G LTE forums. I'm creating this thread to track/support issues from Evita users.
JET performs several useful functions, including:
- Downgrading your HBOOT to 1.09 for easier radio flashing.
- SuperCID (For HTCDev unlocking)
- Partition/IMEI backup.
- Detection of eMMC partitions on a phone stuck in Qualcomm download mode
- Possible unbricking of your device (depending on circumstances)
JET is and always will be 100% open source and with full support given here on XDA.
11/9/12 - Name change to better reflect the direction of this project. Ported to Evita. Rewrote device detection code.
11/1/2012 - Added SuperCID capability
10/24/2012 - Modified emmc_recover to catch stalls at "Wait device /dev/sdXXX......" and try to recover.
10/21/2012 - Added --recover and --unbrick command line options
10/19/2012 - Beta posted
Credit for the original EVO downgrading idea belongs to Mac_Gyver as seen in this post:
This post refined that process and can still be referenced for manual downgrading:

Q: Help! The tool keeps saying "Failed to flash HBoot" repeatedly. What do I do?
A: This is a timing issue. If the tool can't get a good lock on your phone, it will give and error and then try again. It will keep trying until it locks onto the phone and can flash. In addition, it is safe to unplug and replug the USB cable during this step, even to another USB port.
Q: This thing is taking forever!! Is it supposed to?
A: The process usually takes about 10 minutes but can take 15 or longer depending. Unfortunately the process for flashing the bootloader is rather painful, and has to be done in very small pieces. Thank HTC for that one. Ubuntu is also partially to blame.
Q: Is this a bootable CD? Can I use this from Windows?
A: This is NOT a bootable LiveCD. A LiveCD version (with further enhancements) is in the works.
Q: Is there/Will there be a Windows version?
A: No. Nor are there plans to make a Windows native version. There are some inherent issues with the way Windows deals with USB devices that prohibits us from accessing QDL. If you're not comfortable trying/using Linux, I suggest you wait for the LiveCD to be finished.
-b or --backup : Backup mode only (make bakp4 and fsp4, don't force QDL) -c or --cidpreserve : Don't SuperCID the backup P4 file -d or --detect : Find device (/dev/sd?) -k or --kill : Soft brick the phone by corrupting P4 (be careful with this) -r or --recover : Load HBOOT 1.09 and existing backup P4 (for people who stalled after QDL force) -s or --supercid : SuperCID mod for nonbricked phones -u or --unbrick : Load existing backup P4 file ONLY. (Quit QDL without downgrade)

I use a modified version of Fuses emmc_recover. I have forked his source here:
