Click to collapse
try disabling your wLAN security and try again
Have you tried factory reset ?
I think that the factory reset would solve the problem
Go into recovery and erase data, cache and dalvik-cache.
That will hopefully fix it
If not, try turning bluetooth on then using wifi

TB-X505F (Lenovo Tab M10), could not activate wifi and bluetooth any more

Hello,
I have a TB-X505F (Lenovo Tab M10) with the stock ROM TB_X505F_S001149_221115_ROW.
It is rooted and I tried different Magsiks/Zygisk modules.
From one moment to the next, WLAN and BT can no longer be activated. If you move the slider for turning on WLAN to the right, it jumps back to off a few seconds later; the same with BT.
What I have already done:
- Reset network settings via Settings -> System
- Factory reset via Android
- Factory reset via TWRP
- Factory reset via StockRom recovery
- reinstalled the rom with LRSA.
- Reboot with and without SD card
Do you have any idea what that could be or what else I could try?
With a cellphone module I read that an IMEI can get lost and that the module can no longer connect to the cellphone network.
Is there something like that with the MAC address of the Wifi and BT interface?
Thanks.
