Under no circumstances can restore QCN, but can backup NO ESN, NO IMEI, NO BASEBAND, NO WIFI, NO SIM( i remember that i clear both 1 and 2, restart, then restore both them to original ,restart, then clear 1, but restore 2 and modem, fixed it) Wifi is normal but SIM shows no signal or just no SIM Some other situations i can't remember for a moment, but i have encountered: Then i restart several times, there's no problem with anything ( i didn't note the checksum again, but in the past situations that i remember, the checksum of modemst2 will not change if there are not special reasons ) Then i note checksum of modemst1 and 2,restart, both of them changed, restart again,modemst1 change, but 2 no changeĪfter that, i use QPST to backup XQCN, restart, modemst2 changed then i clear modemst1, restore modemst2, restore modem (it's baseband, cause i edited mbn_ota.txt before, don't know if it will be helpful to you), restart, work fine, and NV_item have been restored. i restore original modemst1 and 2,restart, it shows no SIM.Ħ. i clear both modemst1 and 2, restart, still no signal.
after switching volte, it didn't work, restart, then the phone shows no signal.Ĥ. after editing mbn_ota.txt, then clear both modemst1 and 2, restart, nothing happened.ģ. first, i edit NV_item 06828, and then restart, nothing happened.Ģ. This may seem too confusing, let me recall the last time i did thatġ.
