WiFi not working after flashing custom Rom - Redmi 9 / Poco M2 Questions & Answers

(NOOB ALERT)
Hey
today i flashed magisk on and got root but i couldn't turn on WiFi, and right now i cant do anything with that, any help please?
(my first post sorry if did smt wrong)

Following the thread with the same problem
I'm on LG V30 H930, I've tried Lineage 16, 17.1, 18.1 and the newest Dirty Unicorns OS + Magisk 22, couldn't turn on the wifi on any of them (it just showed "looking for wifi networks" and didn't detect any)
EDIT: Apparently it's because I'd flashed PIE after downgrading to oreo to root the device and it made permanent changes to it. One way out is to use a permissive kernel but it only solves some problems.

This guide fixed it in my case (it's a different device but maybe you'll find it useful): https://aakashverma.com/guide-on-lg-v30-aosp-roms-troubleshooting-recommendations/

[PROBLEM] Kernel Panic and Wifi greyed

A friend of mine asked me to repair his brother's phone that recently showed a "Kernel Panic" error message on 4.1.2 stock rom (followed by reboot). I read on the internet that it could be caused by a hardware failure but someone "fixed" the problem installing an AOSP rom (I know, it doesn't make much sense but it seems to be working for now). I installed cm11 by janice and AOSP Rc3 by J-Team (I can't provide you the links but they should be both in the Developement section for this phone). They both worked smoothly and kernel panic has not showed up (for now) but then, when I got everything working, I noticed I couldn't use the wifi function because the on-off switch is greyed out and unable to work. In the Wifi tab I got this constant message (Searching for Wifi network - translation may be inaccurate). Is there anything I can do to fix this problem via software?

Rom HTCLegacy CM12.1 Can't turn wifi on

Hi everyone,
I just installed the HTCLegacy Unofficial Cyanogenmod 12.1 rom (CM12.1 Beta 0) and I can't turn the wifi on, the option even seems to be completely disable.
Is there anyway I can fix this ?
Others don't have this porblem, I may have done something wrong when flashing the rom...
EDIT : I solved the problem by re-installing completely the rom, clean and fresh. Wifi is now working

boot.img incorrect -> lost Wifi features, how to get correct boot.img back?

Hello,
I had the intention to install CM13 on my newly purchased Mi5 (that came with "MIUI 7.3.4.0 Global stable"), so after unlocking, I tried to install TWRP on it at first. Because of the technical problems this currently still involves, looking for a solution, I stupidly flashed an incorrect boot.img on my device (originating from this thread that was about another MI5 ROM version). Now the device still works again after a factory reset, but without any Wifi features (Wifi connection, thethering).
Does anyone know how to fix this? I couldn't find any resource linking to another boot.img (I guess I'd need one for 7.3.4 Global) so far and I'm not familiar with Xiaomi phones enough to help myself otherwise.
thanks, r.

WiFi Issue on LineageOS

Hey, I've got a problem with my OnePlus3T.
When I install LineageOS from https://lineageos.org/ for the 3T, I'm getting WiFi Issues.
It's connecting on and off and I don't know why.
I tested Firmware OB10. 11 and 12 and all of these firmwares I'm facing the same issue with the wifi.
I already installed OOS Openbeta (the latest, 12) and then installed lineageos over it, but I'm still having this wifi problems.
Anyone who can help ?
Can be closed, the normal OOS OB11 doesn't work somehow, but this of Boeffla.

Reverting from Lineage 14.1 to Stock 6.0.1

Hello.
I had my z3 compact on MM and then I rooted it and installed the now-Discontinued ROM by Wajk Wich was pretty stable and everything works.
Then when Nougat came I tried Lineage 14.1 by tomascus Wich was all good and new things, but the hotspot didn't work.
After that I tired the https://forum.xda-developers.com/z3-compact/orig-development/oreo-unofficial-omnirom-t3696536"]Omni Oreo 8.1 by devil188[/URL] that had more features and new stuff than those two.
Of course I liked it but I'm missing the stability 6.0.6 had... Wich everything at least worked as they should.
I now have GPS issue(maximum accuracy is 1KM... Always shows a radius instead of pinpointing me, can't navigate with that in cities) and hotspot issue (can't share my internet to my other devices) and can't use the wifi (finds nothing) so I wanted to get back to 6.0.6.
I tired flashing the 6.0.6 but the flashtools said "bundle invalid" and my device was "unknown" and I had to select it manually.
I tired a lot and I always end up at nothing ... So I flashed the 6.0.6 twrp and them wiped everything and installed the flash able ZIP, and got bootloop, waited an hour and many restarts but nothing happened.
So I tired the Nougat and finally that came up, but still same issues (a bit better thought, wifi works at least).
So how to revert back to 6.0.6? Flashing the .ftf didn't worked, device is unknown... And "bundle invalid" in flash tools (tried the latest and 9.18 version).
Have anyone gone through such a process?
Any ideas?

* You can download Emma a flash tool from Sony.
* When you start Emma and it shows up a login screen, then you have to make a new file in the install folder which is called: "customization.ini" and its content: "developerworld/enable = true" After adding this file the Program should start normaly.
* Then you press volume down 5s and connect the cable to your computer.
* Emma should recognise your phone and give you a flashable stock rom.
greetings

Did you try Omni Nougat? For me everything worked on that rom, no reboots/ loops/ crashes. GPS, wifi, hotspot and bluetooth worked fine for me (I'm an everyday GPS user).

Hello, no I haven't tried Omni Nougat, only Omni Oreo and Lineage 14.1 Wich I am at now, and SliMM 6.0.1 Wich I was back then.
Thanks for the reply, can you send me the link so I can try it before reverting to MM?
