Updating the modem firmware of the ZTE MF286d

@stich86 How can i send and receive AT commands in nordic stock firmware? I need to send ATI to see if the modem is still b11

I updated the modem via openwrt from b02 to b11 and minicom shows that the modem was updated to b11.

I then restored to the stock nordic firmware via ZTE Framework to "nordic to nordic b11pw admin" the flash was successful, but in the web ui there is an update that fails every time
 
If you have restore whole router with ZTE framework, internal module is back again to B02..

You have to update module using FOTA commands via ADB, then put back router to stock mode using uboot restore command (so the mtd8 and 9) and not ZTE Framework, otherwise it will reflash also the module with version B02

Oh. Well, now there's an hour completely wasted. 😅
Regarding my question on sending at commands is it possible without openwrt flashed?

@stich86 So i flashed the router with Nordic to Nordic zte mf286d 192.168.32.1 pw --- via ZTE framework and extracted the Password. the webui and modem are both b02
I followed your procedure but the It states " no updates found! Have the updates been removed from the ZTE server?

set time to 3am
1. Disconnect LTE
2. nv set imei=866754040397403
3. nv set imei_tmp=866754040397403
3. nv save
webui shows imei 866754040397403
4. turn LTE back on and click update

did you get update log using stock framework?

not sure that ZTE still have updates on their server, sorry I don't have this router anymore

Good call 😥. Where would I find the update logs?
Looks like its openwrt to update the modem and restore a B11 router image. I read somewhere that I only need to restore mtb8 and mtb9 is this true?
Do you know how to write mtb9 back from backup?
Thanks again mate

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 :))

Updates from B02 are not available on the server.
I suggest using OpenWrt to update the modem then flash Nordic_B12 partitions.

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 https://dl.eko.one.pl/orig/zte_mf286d/NORDIC/B11/mtd8.bin
mtd -r write /tmp/mtd8.bin /dev/mtd8

A hard reset now shows Nordic_MF286D_B11 in webui and the modem is BD_TELIAMF286DV1.0.0B11
the FOTA downloads the update for b12 but it fails to install :(
 
just take a look to update.log into /cache folder
past it on pastebin, so we can check why it's failing

i can't find a /cache folder
I renamed mtd8.bin to web.img and mtd9.bin to root_uImage_s and reflashed them to the router and its updated to b12 successfully now
thanks for your help

I have managed to flash openwrt to my 286d (Three router) and I'm trying to upgrade the modem firmware in the hope that it will fix an issue with QMI not being able to start the netowrk.

My modem firmware version is 07 and the modem firmware upgrade Mega link doesn't have a patch for the 07. Has anyone come across a patch for this version or know if one of the patches will still work?
