Debrand e blocco bande su ZTE MF286D TIM

nemo1988 Oddio, così spesso mi puzza. Non ci metterei la mano sul fuoco che sia il FW nel tuo caso. E non sei il solo quì che se ne è lamentato in passato però più di questo non so aiutarti perché andiamo in un campo complicato e rischierei di metterti fuori strada. Urge consiglio da esperti di reti mobile.

Ciao, per caso qualcuno sa come fare un backup del firmware originale di questo router? Grazie

Ma chi era rimasto bloccato al firmware Elisa B06, è poi riuscito ad aggiornare in qualche modo? Il mio sembra non volerne proprio sapere..

sam_martello Yes , you have to connect to terminal ,and temporarly set IMEI to router orginally from Elisa.
Or other advanced tricks with communication beetween MF286D and ZTE server and substituting this part in right place

I want to upgrade my router to b12. I changed the imei when the Internet was turned off with the nv set imei=866754040397403 command, saved it, it was displayed on the main page, but no updates are coming. What should I do?

update nordic mf286d firmware from ver b03 onwards
serial requirements to connect to the modem
modem with sim inserted
connect the serial port to the modem wait for the modem to finish starting up
on the gui on page 192.168.32.1 disconnect lte connection
via serial, give these three commands
nv set imei=866754043693436
nv set imei_tmp=866754043693436
nv save
these commands give a temporary imei (it resumes its original when restarted)
on the gui at page 192.168.32.1 reconnect lte connection and search for the update
it will probably go from b02 to b05 then every time you want to update to the latest b011 start over.

I did everything according to this guide, but starting with the Nordic_MF286D_B02 firmware, he does not want to look for new updates.

Does the new imei appear in the gui?
if the new imei does not appear with f5 refresh the page then look for the update

Yes, the new imei is displayed but "No new version found".

trenti60 It didn't help(

Ramil009 but what version of nordic do you have on the modem the one with admin password or different password

with a random password

Ramil009 I don't know what else to say, sorry

trenti60 Thank you for trying to help

Ramil009 You need to set the NTP to 03:00 AM.

This is the italian guide to update to Nordic B12: https://forum.fibra.click/d/15002-debrand-e-blocco-bande-su-zte-mf286d-tim/2308

MentalBreach This is if an update has already been found and in order not to wait for the night, you can change the time. For me, he just doesn't want to find new versions.

Ramil009 small note:
but you after you have changed imei and updated the page 192.168.0.1 and you see the new imei appear,
disconnect and reconnect lte connection
and then looking for the update?

trenti60 everything exactly as written in the instructions
