Had this same issue a couple of times, on different ROMs. Ive tried many many ROMs, first time it happened was on a fresh install, when I tried loggin in to the wifi network it was like stuck, never said connected to network, it was looping on authenticating and going back to searching, all kinds of "$#%. Tried re-flashing, nothing... well decided to go on another MIUI based ROM, worked fine. Second time it happened was trying EUI 5.0 everything was soooo fine, until out of the blue after a reboot (3 days using the ROM with no issues), same crap happened with the WIfi. Didnt want to re-flash cause all of the chinesse bloat, decided to try cyanechy 2.1 based on CM12.1 working fine. Anyways, try a different ROM it will work at some point. Weird issue though.
It's a helio x10 bug I think they were supposed to fix it with an update
I've flashed sMIUI 8 but still no WiFi
I'll try cm13 if that change anything...

I've tried flashing the full raw ROM from Xiaomi but stii no Mac and imei
So the point is how to restore it??

Problem with WLan Mac address and WiFi not turning on

Hi all..
I'm running miui.eu ROM ... latest weekly .... been running for a few months now ...
recently, my Wifi refuses to turn on ... the mac address shows 02:00:00......
as a temp workaround, I need to activate airplane mode, turn on wifi , reboot , connect to the wifi AP and then turn off Airplane mode ....
I searched a lot but all threads are for different devices and none for the Poco F1 ...
Could someone please guide me in the right direction ?
I instaled miui eu 9.4.18 and then dirty flashed the newest one mini eu and wifi now is ok

On OP3, I also had no wifi all of a sudden. If I turn on wifi, it will automatically switch back to off in a couple of seconds. A dirty flash of the ROM solved it. Try it though it is a different device.

No Wifi on Android 10 Roms

I've been running Floko Rom v2 ever since I got this tablet without any problems. I've now tried the following Android 10 roms Bliss, Floko, Pixel Experience, crDroid they all have the same issue; I cannot turn wifi on, I select the toggle the tablet thinks about it for a few seconds then wifi toggles off. I reflash Floko Rom v2 and wifi is back again. Does anyone know how to resolve this issue? I would really like to try one of the Android 10 roms.
Thanks

does custom os fix random reboot during call issue on redmi note 9 pro

hi
my friend own redmi note 9 pro
and have 'known' issue of random phone reboots during calls - like at least once a week during call his phone reboots itself
it was send to 'warranty' repair 3 times ! but they did not fixed anything.
so my question is
IS THERE ANY CHANCE THAT CUSTOM OS WILL SOLVE THIS ISSUE? lineageos for example?
or does anyone had this kind of issue with his one and custom os was the solution ?
thanks and regards !
It happened to me that my RN9P joyeuse restarted several times during a phone call or just while using it. The problem was fixed for me during the update (I think miui 12.5). It was probably a software bug when the phone tried to switch between LTE and another network which caused a restart. I am currently using the ForkLineageOS custom rom on android 12 and there are no reboot issues, previously i used lineageOS and pixel experience on android 11 and there were no problems either.

Can you review lineageOS for me?, is it good?, stable, and how to install it
not on rn9pro but on my redmi 9 everytime I try to call "*143#" my phone just magically reboots, and also the reboot persists too when I try to maxxed out the volume.
