TISH1TTY

TISH1TTY is a modification of BadRecovery (formerly OlyBmmer) and is a tool allowing you to perform an RSU unlock on Ti50 devices such as nissa and corsola.

Usage

First download a nissa or corsola R124 image and run these commands:

git clone https://github.com/kuromuiroha/TISH1TTY
cd TISH1TTY
sudo ./build_badrecovery.sh -i <image.bin>

Then flash to a USB drive

Alternatively, download a prebuilt for nissa or corsola and flash to a USB drive

Now, enter recovery mode (power + esc + refresh) and plug the USB in. After recovery, it will run the BadRecovery payload, then prompt you to run a TISH1TTY payload, which will process codes. Once the code is found, it will RSU unlock, which will enable factory mode and restart, also disabling WP.

Testing

If you want to run the scripts on a device in chromeOS, run these in VT2
for nissa:

cd /home/chronos/user/Downloads
curl -O https://raw.githubusercontent.com/kuromuiroha/TISH1TTY/postinst/TISH1TTYnissa
chmod +x ./TISH1TTYnissa
./TISH1TTYnissa

for corsola:

cd /home/chronos/user/Downloads
curl -O https://raw.githubusercontent.com/kuromuiroha/TISH1TTY/postinst/TISH1TTYcorsola
chmod +x ./TISH1TTYcorsola
./TISH1TTYcorsola

for bash version:

cd /home/chronos/user/Downloads
curl -O https://raw.githubusercontent.com/kuromuiroha/TISH1TTY/postinst/TISH1TTY.sh
chmod +x ./TISH1TTY.sh
./TISH1TTY.sh
