[Please help] SIM cards not detected after flashing stock rom - IMEI preserved [sc9863a phone]
(15-10-2021, 11:00 AM)johntrevor Hello everyone,
first of all I want to thank again the forum Creators and Moderators for this great community, there are a lots of stunning tutorials to learn many many procedures.
I ask for help, basically Thread title: on a Alcatel (TCL) 1SE 2020 (model 5030D, Android 10, chipset sc9863a)
which I succesfully rooted - it was model "a" from a previous thread - I wanted to revert back to stock firmware after some experimental mods on base OS.
- So first, I downloaded a stock .pac for my model (found one on needrom dot com)
- ReserachDownload tool, I flashed back all the backup firmware files except NV_LTE (software gave me an errore "Incompatible partition"
- So I flashed the NV_LTE information via fastboot: fastboot flash l_fixnv1 ltemodem.bin
At first OS setup, SIM cards are not detected.
In Setup>About IMEI are preserved like the original ones
In Engineer Menu, "Set IMEI" is absent and I cannot tweak any radio / LTE related function because "No SIM is deteted".
Please help, how can I do to make SIM detectable again? Thx

what files do you have in this backup of yours?
how and when did you make this backup? e.g before you flashed the device?
have you tried factory resetting the device?
have you tried flashing stock firmware without restoring any backup?

Flash the downloaded pac and try doing a factory reset. You could try factory download tool for flashing
