Like many of you, this device does not have the "OEM Unlock" option in the Settings - Developer Options.

Hence, I believe the OEM unlock is actually enabled. Following this, I used adb reboot bootloader and then entered the fastboot flashing unlock command to successfully unlock the device.

Next, I attempted to sideload a userdebug mode GSI (i use "andyyan-gsi") using the "dsu sideload" tool, but it didn't work as the device got stuck at the logo during boot. However, I noticed that the device was still accessible via adb. I discovered that the adb shell could switch to root using su -. This indicated that the GSI was successfully flashed, but some customizations from the manufacturer prevented it from taking control of the display.

Afterwards, I reinserted the TF card to get it recognized (on my device, its name is mmcblk0p1, and you need to manually mount it to an empty directory). Then, I used "dd if=/dev/block/mmcblk2 | gzip -c > /xxx/xxx/xxx.img.gz" to back up the entire eMMC to the memory card and "dd if=/dev/block/by-name/boot_a of=/xxx/xxx/xxx.img.gz" to back up the boot partition. The next steps were straightforward: use Magisk to patch the boot image and flash it (note the fastboot a/b slot). The first boot after flashing will be slow, so just wait patiently.

which gsi package you used? could you share you boot.img?

Confirmed, on the Meebook M6, the system image can be obtained by sideloading the GSI image on the DSU.
Package lineage-19.1-20250118-UNOFFICIAL-a64_bvS.img.gz from Andy Yan is available. Remember to back up the entire eMMC data first.
It should be noted that Meebook M6 does not support temporary boot using " fastboot boot <boot.img> " commands. also, adb on recovery is broken.

Rename to .zip (or open with 7zip). However because this is an 'incremental' update, it cannot be extracted (properly) with any of the existing tools available.

I am very close to getting working firmware files (to restore bricked devices), and will update the thread as soon as I have them.

pls update link
