In the new year, I'll focus on ways to avoid a permanent brick, and making flashable PKGs to ease every installs and mods.
|
|
|
|
Greatly thank all who donated. Thanks for being supportive to all and we are a great community. Happy new year!
|
|
|

Note on 12/28/2018: :D great news! My DPT is alive (not in my hand yet)! I'll be much more careful in the new year.

# 0x1 Special Thanks

Greatly thank

* [shankerzhiwu and his friend at XDA](https://forum.xda-developers.com/general/help/idea-to-root-sonys-e-reader-dpt-rp1-t3654725/post78153143) who made the USB hack possible, and fixed my bricked DPT (not so easy)
|
|
* [octavianx](https://github.com/octavianx/Unpack-and-rebuild-the-DPT-RP1-upgrade-firmware) who sheds light on the hack
|
|
* [janten](https://github.com/janten/dpt-rp1-py) who initiates the commandline tool for web APIs
|
|
* `silvertriclops` who points out bugs in `get-su-bin` and "forces" me to test it :D

# 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](https://github.com/HappyZ/dpt-tools/blob/master/fw_updater_packer_unpacker/README.md) for more details.

# 0x4 Tutorials

|
|
Most people would be interested in [the Rooting Guide](https://github.com/HappyZ/dpt-tools/wiki/The-Ultimate-Rooting-Guide).
|
|
|
|
Details in [wiki](https://github.com/HappyZ/dpt-tools/wiki).

|
|
|
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:
|
|
|
|

|
|
