ZTE MF269 Stock firmware backup/restore and memory mod (MF269/AX6/AX3600)

For Developers
1

Good morning everyone!

Since the stock firmware of the ZTE MF269 (OpenWrt info page) is not available online, I would like to know if anyone has managed to find a working procedure to extract it from the device and then use it to return to the stock version. Here on the forum I have read several posts and procedures regarding other models and, as I understand, there is no universal method to do it unfortunately.. https://forum.openwrt.org/t/copy-original-firmware-dev-mtd-for-restore/172916/1

I also wanted to point out that there is the possibility to increase the internal memory available, for MF269/AX6/AX3600, but I have not been able to find precise information about it.

I hope someone will go into more detail about this because it is really a good device. Unfortunately I am not a programmer and I have only installed openwrt on some devices!

Thanks to all!

When i was installing OWRT on my MF269, before flashing the firmware i took a full backup of entire flash contained stock firmware.
I think it's gonna work for you if you find a way to restore the necessary partitions from my backup.
As I know the origin flash has some partitions. when installing OWRT, only one or two of them are replaced with the OWRT stuff. so you need to find out which are those partitions and find a way (script, linux command, ..) to restore those partition back you got it.
here is my back up partition list:

hope it's usable for you. please let me know if you need this back up.
