For update logs I mean the pop-up that will shown when you click on the check button. If now messages, probabily the ZTE server has been cleaned.
To flash back sto firmware just stop uboot at the begining, do a
printenv or
env print (i don't remember which one is correct) and check for alias command to write
root_uImage_s and
web.img. Use the whole commands after the alias to write back the two mtd.
Note that you need a TFTP server and the ip address of your PC should be the one into value
serverip
If you haven't erased the mtd9 on OpenWRT, just restore mtd8 (or viceversa, you need to restore only rootfs

)
Hey mate sorry for the million questions.
I have flashed to b11
( i was hoping to see if the b12 update would install FOTA, idk why just wanted to see)
I'm really stuck on how to flash back to nordic b11
I dont not where to get or make root_uImage_s and web.img or how to flash them.
I flashed mtd8.bin in uboot from a nordic b11 dump but the webui is showing NORDIC_MF286D_B02 modem is still b11 though
load mtd9 into ram via tftp server by:
tftp mtd9.bin
- erase mtd9 by:
nand erase 0x1800000 0x1d00000
- write ram into mtd9 by:
nand write 0x84000000 0x1800000 0x1d00000
####################
I did write mtd8.bin in open wrt before mtd9.bin

cd /tmp
wget
