Xiaomi Redmi 7 Y3 (India)
Works with selinux=permissive, VoLTE untested, all other hardware works.
Using the Xiami tool or Penn5's tool
2. Flash stock rom V11.0.2.0.PFLMIXM_20191022
Not sure if you need this, but this is what worked for me.
Note: I've made sure the device is not rebooting after this step by uncommenting "fastboot reboot" in the second last line of "flash_all.sh" below. This enables the GSI ROM to run the device encryption.
$ wget https://bigota.d.miui.com/V11.0.2.0.PFLMIXM/onclite_global_images_V11.0.2.0.PFLMIXM_20191022.0000.00_9.0_global_b0cd3cab92.tgz
$ tar -xzvf onclite_global_images_V11.0.2.0.PFLMIXM_20191022.0000.00_9.0_global_b0cd3cab92.tgz
$ cd onclite_global_images_V11.0.2.0.PFLMIXM_20191022.0000.00_9.0_global
$ cat ./flash_all.sh | sed "s/fastboot reboot/#fastboot reboot/g" > flash_all_no_reboot.sh
$ chmod u+x ./flash_all_no_reboot.sh
$ ./flash_all_no_reboot.sh
This was necessary because otherwise the boot img halted with a dm-verity exception and the device was stuck in a boot loop.
Note: Flashing with --disable-verity AND --disable-verification did NOT enable the device to boot (stuck in bootloader). Flashing with --disable-verity ONLY worked for me.
$ fastboot flash --disable-verity vbmeta images/vbmeta.img
This was necessary because the the GSI ROM I used got stuck while booting with selinux exceptions in adb logcat.
The following commands basically add "androidboot.selinux=permissive" to the end of the kernel cmdline in boot img.
$ cp images/boot.img stock-boot-with-bootarg-permissive.img
$ echo "6d6dd34f63ab42785186e01ca036a751 stock-boot-with-bootarg-permissive.img" | md5sum -c
$ if [ $? -ne 0 ] ; then echo "MD5 checksum of input boot.img not as expected"; fi
$ printf " androidboot.selinux=permissive" | dd if=/dev/stdin of=stock-boot-with-bootarg-permissive.img obs=1 seek=388 conv=notrunc
$ echo "be80a5217ebe846c1e547c14092c4efe stock-boot-with-bootarg-permissive.img" | md5sum -c
$ if [ $? -eq 0 ] ; then echo "MD5 checksum of patched boot.img is OK - patching successful"; fi
If the above patching is successful (you should see the "patching successful message"), you need to flash the result:
$ fastboot flash boot stock-boot-with-bootarg-permissive.img
5. Flash the GSI system image (I've used the current Ressurection Remix GSI)
$ fastboot flash system ARM64_AB_20191205.img
$ fastboot reboot
In Recovery, resize the Data and System filesystems.
Flashing OpenGApps with official TWRP twrp-3.3.1-1-onclite doesn't work, it fails with error 64.
Unofficial version TWRP-Redmi7-LRTeam.img works (mirror, md5 51237373ab26b3057124b3d03bc93f7a, sha256 5cabff51556b2c141b894c8612c347ac7a83be476ad0e77dbbe93d2a943e98b0).
To make video recording work, add media.camera.ts.monotonic=0 to /vendor/build.prop
Enjoy!
