[HBOOT][11/14/12] JET - The Jewel/Evita Toolkit (Linux)

---

Disclaimer: This is BETA. It works well, but may still set fire to your house if you anger it.


UPDATE 11/14/12 - Updated OP with SLS's fix for device detection.


JET - The Jewel/Evita Tool "kit."

JET performs several useful functions, including:

• Downgrading your HBOOT to 1.12, allowing the use of LazyPanda instead of DirtyRacun (S-OFF without having to wipe the phone if you already have root) Note that this is unsupported by Team Unlimited, however it works just fine.
  
• SuperCID (For downgrading firmware via RUU)
• 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.

Changelog

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 downgrading idea belongs to Mac_Gyver as seen in this post:

This post refined that process and can still be referenced for manual downgrading:

Requirements

• Unlocked bootloader and a recent TWRP already flashed. (RegawMOD Rooter works well for this)
• A NATIVE Linux installation, or a LiveCD/Wubi install. Virtual Machines are NOT SUPPORTED.
  
• A 32 bit Linux installation/CD, or install ia32-libs or ia32-libs-multiarch
• Linux Kernel v3.0 or higher (Ubuntu 12.04 LiveCDs meet this requirement)
• USB Debugging turned on

FAQ

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.

Instructions:

1. Boot Linux.
2. Download attached package.
3. Unzip to somewhere you have write access (/home/ubuntu for Ubuntu LiveCD users)
4. Open terminal.
5. cd to working directory.
6. $ chmod +x jet
7. $ sudo ./jet
8. Follow the onscreen instructions.
9. /happydance

Command Line Options

-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?)
-r  or  --recover  :  Load HBOOT 1.12 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)

To do:

• P4 file generation from user entered MEID.
• Merge both HW versions of JET and detect device at load.
• LiveCD

LiveCD Development is underway. You can follow the code here:

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

A big Thank You to all who've sent donations! Caffeine and beer help generate code, and a few extra bucks convinces the wife it's worth the time I spend glued to my PC/phone. Your donation money is also being used to buy devices to further test/develop with.

o yut!!!! ill take 1#

i'll take #2!

I already have s-off but this is sweet!

Fixin' to unlock mine. I might give this a shot.

nice to have this around

Never done anything like this, but I understand all the terminology and I'm pretty sure I understand what happens every step along the way. Never used Linux, but I can follow directions, so I think I might try this...

PM me.... I'm about to start round 2 of testing and I need a couple more testers.

Done and Done

I'd volunteer but my partitions are borked somehow and now I have to try and back up my data so I can reinstall everything. Somehow this has to be the gf's fault, I caught her running as root the other day just so she could change the font color on the time. *sigh*

Take it out of that $200 you owe her.
