Please helpThis is what I did|
1. I was on MIUI 10 Global 10.3.2
2. I flashed Xiaomi.EU Oreo... it was working fine
3. I flashed Xiaomi.EU Pie... it was also fine
4. I decided to flash back MIUI 10 Global 10.2.1
this is where my troubles began
1. No SIM detected when I insert both SIMs, sometimes SIM 1 is briefly detected then it disappears
2. Same Issue when I only insert SIM 1
3. When I insert SIM 2, I can only use 3G/2G data, phone calls are completely silent
4. When I try to flash any ZIP in a custom recovery, they always fail with:
Error 7 and
E1001: Failed to update system image
What I have tried
1. Flashing global rom
2. Flashing China rom
3. Flashing original MIUI 9 rom
4. Flashing above roms through EDL
5. Flashing modem only
6. Flashing old modem
7. Sent to a service center to have the SIM components changed.
Any help would be appreciated, please and thank you if you took the time to read this through.
