0x0 Welcome

Donate via , or if you can, please simply go to my blog post here and click the Google advertisement for me to get a sip of coffee.

Note: Scripts and mods are only tested on MacOS. I do not plan to support all platforms. Use it at your own risks.

0x1 Special Thanks

Greatly thank

• shankerzhiwu and his friend at XDA who made the USB hack possible, and fixed my bricked DPT (not so easy)
• octavianx who sheds light on the hack
• janten who initiates the commandline tool for web APIs
• silvertriclops who points out bugs in get-su-bin and "forces" me to test it :D
• Thank all who who donated. Thanks for being supportive to all and we are a great community.

0x2 What does DPT stand for?

[cough cough] If you don't know what's DPT you won't need this.

0x3 Tools Intro

dpt-tools.py - Automation to gain root, adb, and sudo access

Heads up! Use this at your own risk. It has only been fully tested on Macbook Pro.

This is an interative shell commandline tool that wraps processes like updating firmware pkg, obtaining diagnosis access, etc.

fw_updater_packer_unpacker - Automation to pack/unpack pkg

Note for developers: Absolutely do NOT exit 1 while your script (in pkg) has errors. This will create an infinite loop of "system start -> update via pkg -> shutdown -> restart -> update -> shutdown -> ...". I learned the hard way and there is no way to fix it (soft bricked).

To flash pkg with unverified signature, you need to modify the updater file at /usr/local/bin/start_eufwupdater.sh.

Check this README for more details.

0x4 Tutorials

Most people would be interested in the Rooting Guide.

Details in wiki. I have made flashable PKGs so you do not need to go through nasty steps any more.

Note: if Launcher crashed, try in ADB sudo:

cd /data/system
mv ExtMgr.db ExtMgr.db_bak
mv ExtMgr.db-journal ExtMgr.db-journal_bak

0xF Mission Impossible

Well, to bypass pkg validation, you can also try to decrypt the RSA key and generate corresponding private key, when we actually have enough computation resources and time to do it lol:

> openssl rsa -pubin -in key.pub -modulus -text
