Meebook M7 Firmware Thread

[musickid]

For this nice device, I would like to see more support and an effort to root/twrp.

Here is what I have so far:

Firmware files from OTA Update v1.5.4: [Download]



Firmware Files Dumped using rkDumper: [Available upon request]


I have tried every utilty I could find and none are able to extract the boot.img nor system.img at this time - it appears.

I finally decided to look at the files in a hex editor and it turns out most (all) of them are empty or corrupt. I've had to delete the firmware linked above in case anyone tries to flash those files.

Here is a link to the captured OTA Update file: https://drive.google.com/file/d/15-w...ew?usp=sharing

I think the issue is this an incremental OTA update and I have yet to find a way to properly extract the contents.

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.

Yes I tried otadump and all alternatives. payload_dumper requires a dump of (or stock) firmware files.
