Openwrt for zte-mf269

I want to install OPENWRT on the MF269 router model, but the snapshot version is available and there is no tutorial. Has anyone here installed this snapshot version for this model and guide me?
This link is the snapshot of this model:https://firmware-selector.openwrt.org/?version=SNAPSHOT&target=qualcommax%2Fipq807x&id=zte_mf269

See what is in the commit.

For the initramfs mentioned in the sparse instructions,
You can take a look HERE

KERNEL from the link OP posted, is the initramfs you mention.

Hi fellows. Is there a way to recover a bricked MF269 ? Stock firmware ? How to activate recovery/download mode ?

via serial ... ?

Yes, please. Or any other way around

please what ?
you own the device, what else do you need from us ?

I need a way to flash stock firmware to the device I own

I'm asking again, what do you want from us ?

Do you know how to set the device to download/recovery mode ?

reread and understand Openwrt for zte-mf269 - #6 by frollic ?

I do have a serial access to the board, is that the answer you were expecting ?

great, then try using the boot loader commands to perform a device recovery, and reflash it with stock fw.

we know how you recover back to openwrt, but that's not what you want here.

In fact, getting to run openwrt is my final aim. I have two MF269, one is running stock firwmare but the bootloader won't be intrrupted by keyboard. i.e. Not possible to launch tftpd server. The other one is bricked. Was running and working on openwrt as descibed here but stopped suddenly and has no reponse to serial nor eth. Which way is easier to get there ?

a different USB TTL might solve this issue, it's knows ZTE MFs have problems with some of those.

if serial's dead, it's bricked, you'll need a flash writer to recover, assuming it's not a hw failure.

Used these unsuccessfully.

Where would I find flash writer ?

the one to the right is FT232, they're known to have issues. the other ones I can't tell what they are.

internet ?

Ok. How to set it to recovery mode for flash writer ?
