The qualcomm card runs a cut down version of android, now how to get to adb from stock firmware to update the modem firmware.
Code:
The upgrade phase should be done one by one, so if your modem is at B03, you need to upgrade to B04, then B05 and so on.
To see which version you are currently running, use picocom or minicom and connect to /dev/ttyUSB1 and issue "ATI" command.
You will get an output like that:
Manufacturer: ZTE CORPORATION
Model: MF286DMODULE
Revision: BD_TELIAMF286DV1.0.0B11
SVN: 11
IMEI: 86XXXXXX
+GCAP: +CGSM,+DS
The reviersione is this one: BD_TELIAMF286DV1.0.0B11 <-- in this case is 1.0.0 B11
Extract each file called imageB0XnaB0Y (where X is the current build, and Y is the target version).
If your modem is at build 1.0.0B03, you should use files inside imageB03naB06 and so on.
On the folder where you need to update, copy the two files called "delta.package" and "delta.signature" into /tmp folder of your OpenWRT router (on that machine you should have also ADB package installed)
SSH into router, then goes on /tmp and copy these two files into /cache folder of the modem:
adb push delta.package /cache/
adb push delta.signature /cache/
Then open again a session with picocom/minicom to /dev/ttyUSB1 and to these commands:
at+fotactr=0
+FOTACTR: 0,0 <-- if 0, the modem see the update package
at+fotactr=1
+FOTACTR: 1,0 <-- if 0, validation is ok, 1 is failed, 2 is waiting
at+fotactr=5
+FOTACTR: 5,486202 <-- the last number is the byte of the update package (in this case is 486kbyte for the latest OTA to B11)
!!!! THIS COMMAND SHOULD BE DONE ON EACH UPDATE !!!!
at+fotactr=8
+FOTACTR: 8,0 <-- if 0, this will remove old *.flg file from the /cache directory used by latest upgrade
If everything is correct, issue this command will start the update
at+fotactr=2
After 5 minutes the modem will reboot and bring up again. It's necessary to do another "reboot" that will update the "ATI" command output.
You can do this "twice reboot" just on the latest update, so if you are con B03, go up to B11 (you have to copy each time the delta files), when you have done the latest update, just power cycle the router.
