for EDL stuff you need to dump module itself before.

It's an MDM9230, i think that there should be a loader for it

!!BE AWARE GUYS!!

we have found with MiG25 that swapping firmware on the module will break LED and RJ-11 port

Now we are trying to understand why..

good news guys

EDL recovery was succesfull, so my repack files are good.
Now i've to clean up QCN and check next steps to bring module back to it's normal operation

Hope to finish it tomorrow

when it's done yes, also repack files for the dump that i've (Vodafone IT AT1\AT2, Vodafone DE, T-Mobile PL), otherwise istructions are useless

oh sorry, you're right

just short them to each other while plug the module into USB port, when you get 9008 COM you can remove the short

if we use QFIL (instead of SB3.0) it will be more easily to flash
Let me work on repack stuff, now that I've HW EDL is it more easy to flash

Thanks
Waiting for your feedback

Look here how to open it: https://forum.fibra.click/d/32421-zte-m … dello-vfit

You need to remove all screw to get modem that is behind the mounting cover. Then it slide Mf286d, remove the two screw and it can be removed from the slot

As I've promised here is all stuff created to swap firmware on MF289F module:

https://mega.nz/folder/Lpx20LgJ#bxxiLuF2AH2B78T0vd6vGA

inside there are needed files to change firmware (boot, system, modem and config), qcn and istructions.
Take care when do the swap, if you erase wrong partition (different from boot, system, modem), you can send module into recovery (like MF286D). There are no NPRG/EPRG loaders and also no known EDL boot point, i've the firehose for EDL but without put it in 9008 mode is useless.

As for now, I've enabled VoLTE on two different modules but only in Italy (three different providers), same procedure seems to not work with PLUS sim on T-Mobile module (tested with MiG25)

I want to publicly thank MiG25 for the dump of T-Mobile unit.

Thanks to my experience on ZTE MC7010/801A I was able to repack firmware for MF289F module, now one on my module that was Vodafone IT (AT2 fw) was converted to T-Mobile PL:

Here is also a little speedtest:

Let's see if I can get VoLTE working

ok let's try to summarize (i've tried to create a procedure for Windows, but the modem kill itself after some seconds).

First of all you have to install or use LiveDVD from https://github.com/bkerler/edl/

When booted on this Linux Live, open a terminal. Check if you have adb installed, in case just type:

sudo apt install adb

Then download this firehose programmer: https://mega.nz/file/6g5nQSDD#mr1E2x2sG … KSpwgBHHkg and put on desktop folder

go into desktop folder from the terminal (usually 'cd Desktop' if you are in your home)

then attach the modem with USB adapter, wait 5 minutes and type this command: adb reboot edl

wait 2 minutes then type these commands:

mkdir dump_by_parts
edl rl dump_by_parts --memory=NAND --loader=prog_firehose_mf289f.mbn

If anything was fine it will start to dump all partition inside that folder

When finished, copy that folder into an usb stick and upload files into a Mega folder

Regarding QCN i think that anyone know how to do it, in case with EFSPro remove IMEI

hello guys,

loooong time from my last post

now that i've knowledge on reflash also embedded module, i'm searching a different one from Vodafone (that has some issue when you enable VoLTE).

I need a dump of the module itself (plus the board and QCN). Let me know if anyone can help me, I can share procedure to dump it (needs linux machine)

Thanks in advance!
