Sync a twrp minimal manifest, patch it for building Matrix Recovery, and sync the Matrix Recovery sources

To fetch the manifest for the first time, follow these steps:

---

1. Fetch these sync tools

mkdir ~/Matrix_Recovery_sync
cd ~/Matrix_Recovery_sync
git clone https://github.com/Matrix-Recovery/matrix-sync

2. Do the syncing (this can take up to 1-2 hours, and can use up to 40GB-80GB of disk space) - below is an example, for 12.1 (amend as required for other branches)

cd ~/Matrix_Recovery_sync
./matrix_sync.sh --branch 12.1 --path ~/matrix_12.1

Notes:

• You MUST supply an ABSOLUTE path name for the "--path" switch
• If the sync process gets stuck, you might need to terminate it with Ctrl-C and then run the script again
• If you want to use ssh for cloning the OrangeFox sources and vendor tree, export "USE_SSH=1" before starting, or supply "--ssh 1" on the command line
• After the initial sync process, you must then clone your device trees, before you can build for your device

These manifest branches are supported by the matrix_sync.sh script:

---

14.1
12.1

To update the manifest, and the recovery sources, and the vendor trees (given the example of the 12.1 branch above), follow these steps:

---

cd ~/matrix_12.1/
repo sync # (ignore all errors and suggestions relating to "android_bootable_recovery")
cd ~/matrix_12.1/bootable/recovery/
git pull
cd ~/matrix_12.1/vendor/recovery/
git pull

To update only the recovery sources (given the example of the 12.1 branch above), follow these steps:

---

cd ~/matrix_12.1/bootable/recovery/
git pull

To update only the vendor tree (given the example of the 12.1 branch above) follow these steps:

---

cd ~/matrix_12.1/vendor/recovery/
git pull

To update only the manifest (given the example of the 12.1 branch above), follow these steps:

---

cd ~/matrix_12.1/
repo sync # (ignore all errors and suggestions relating to "android_bootable_recovery")

To see the syntax of the matrix_sync.sh script, follow these steps:

---

cd ~/Matrix_Recovery_sync/sync/
./matrix_sync.sh --help
