Help: Note 7 SM-N930F no SIM-CARD Detection

[feiercrack]

Hi friends,

my Note 7 SM-N930F wont recognise the sim-card again.
if it reads it, after a split second the phone says: please insert sim card

my N7 is rooted, Hydra 1.45 rom and shieldx installed which prevents the phone from the disabling OTA updates etc

but now, since last saturday it wont use the sim card again. i tried several sim-cards, they work well in other smartphones and tablets.

what can i do now?

i´ve checked the IMEI status for beeing blacklisted or not, but a few websites says it is clean, other websites says not.. i dont know, which site to believe for now.

i dont have any special hardware to use current z3x samsung pro tool manager software...

i like to read the cert from inside, and add dual-sim function to test the other sim card slot inside (i have bought that dual tray separately)

how can i read/edit those certs without special hardware?

or

what can i do to get my phone back working?

i already flashed this stock rom,

AP_N930FXXU2BPI7, BL_N930FXXU2BPJ8, CP_N930FXXU2BPJ5, CSC_OXM_N930FOXM2BPI5 / HOME_CSC_OXM_N930FOXM2BPI5

format,wiped the phone and after that using my 2 weeks old backup via twrp, but the phone will not recognise the sim again...


its an N7 SM-N930F from THL, but i live in germany, using vodafone provider

many thanks in advance

cheers fc

p.s. i already had exactly that problem! that drives me to install the hydra rom and the shieldx software app on phone and files via adb from alliancex. org. then the phone worked well for about 2 weeks...
