WIFI issues on oreo Roms - Xiaomi Redmi Note 4 Questions & Answers

Hey guys,
right now there are lots oft oreo Roms supporting mido, but everytime i flashed one (like cardinal which is working for many users) i cant connect to my home wifi network. It tries to connect, then the signal is dropping and it says "saved" again. On other phones running oreo this wifi is working perfectly. I already disabled IPv6 and it didnt help. So I hope anyone knows how to fix it!

Same here, i had problems connecting to hidden WiFi in every oreo rom i tested. By the way what firmware did you flash when installing your Rom

I have this problem ...happens with Oreo and sometimes with nought

Just tried to install Pixel Experience, Aosp Extended and LineageOs, still same wifi problem with all roms.
Has anyone been able to fix it?

Same here! hope someone gets a fix

Using AEX 5.1 a few days now, no wifi problems. Are you on latest firmware? I got cellular signal improvement with the latest firmware, don't know if it fixes wifi probs too, but if you are not on latest firmware you should try that.

Yeah, I have flashed firmwares since they were extracted and posted here. By the way, I also noted that none of that firmware has helped me with the signal drop issue that was reported since LineageOs 14.1

I'm not sure about it. Because I tested from several wifi connections. And all of them work ok if I try to connect from any Miui rom or any Nougat based custom rom.

i have same problem

Help plz! Cyanogen No Wifi i9300

So my bro got a i9300 S3 (international), its his first android after iphones for years.
Anyway he has tried to install Cyanogenmod and reckons there is no wifi (will show his router but not connect)
Stock works fine but he hates touchwiz.
The steps he has taken are....
updates to 4.3 from Kies
rooted via odin
installed cwm
installed cm10.2 and gapps
He says everything is perfect except wifi, its sees router and saves connection but doesnt connect.
His baseband is i9300buugj3
Now he is really gutted as he loves the stock android look.
Any fixes and steps would be appreciated! (I cant get to him to have a look myself hence the post!)
Perhaps update baseband would fix?? (And if so how would he do that? Via odin? Does CWM being installed affect anything?
Thanks in advance!!

whats the build information of the cyanogenmod that is flashed, i think its a nightly build, sometimes there are different issues in nightly builds, did you tried a stable one i mean M Snapshot, thats a stable one and also does not have wifi issues.

He says he's tried most builds inc Snapshot builds and doesnt work on any, hence he thought about his old baseband (not that he knows the problem)

this happens sometimes, i m too using cyanogenmod myself, when i was using stock rom i was able to connect to my college's router, but after flashing cyanogenmod, i was not able to connect to it, nowdays they have replaced with new router, n there is no problem inn connecting to it, even i never had problem to connect to my home's router, this happens with some router.. maybe this time with your's.. try to connect to other router than your's.
I have the exact same problem
my phone sees the router and saves connection but doesnt connect.
I also tried Wifi tether from my other phone and even that doesnt connect, it just saves the network...
this is happening on all CM based 4.2.2 roms...
havent tried 4.3 and AOSP roms...

are any other devices connecting to the same wifi network? if yes, try factory reset of the phone from recovery and then flashing the custom roms.
Yes the router connects to other devices fine.
He wipes data and cache and dalvik before flashing so??

[Q] Oneplus One(Chinese) WIFI Issue

I can't connect to any wifi network even after data reset. It seems that my wifi is messed up. I came from Color OS cause its chinese version and flashed cm11S and then flashed franco kernel. After sometime i can't see or connect to any wifi even at home, I tried flashing almost all roms but it didn't solve the issue. Phone without wifi is a crap, please help I don't know what to do.

You'll want to install the newer CM11s based firmware. Once you do that, you should have wifi working again, and possibly a better cell signal as well.

Did you install the full firmware? Because it sounds like you just flashed a rom.

[Radio][Modem][5.X.X] Updated Modem and radio files from oxygen os

I thought I might share the updated radio, modem and environment files from oxygen os. So I made this flashable zip. I have tested it on my device and working with cm12 nightly right now. So hope it will work on yours too.
Link: Download Whole Firmware
Only modem
Mirror:
Full firmware
Only Modem
tested os with this firmware: CM12 nightly, Blisspop, CM12.1, Oxygen OS, Temasek rom, euphoria, Tugapower V5
Note: There is some changes I noticed. there is new file called reserve4.img which is being flashed in "/dev/block/platform/msm_sdcc.1/by-name/reserve4". And also the previous sdi.mbn file from "/dev/block/platform/msm_sdcc.1/by-name/dbi" is missing. Now I checked the updater script in oxygen os and noticed that its not removing the old sdi.mbn. Its just installing the reserve4.img as an addon. So I kept both the files in the flashable zip and it seems to work good. No issue so far.
Caution: DO NOT USE IT WITH CM11/CM11s/or ANY KITKAT ROM!
It will brick your device. Only flash on lolipop based roms. After you flash this, if you want to go back to cm11/cm11s, flash the latest cm12 nightly first and then install the cm11s files.
Are you saying that cm12 boots fine with this firmware? Sorry I don't understand well your post.

yes! using cm12 nightly 02/04 release with this firmware right now
But then if you want to go back to the old modem Cyano ... How should we do ??? But by flashing this new modem, you have to flash even the Fix for Proximity Sensor?

Official cm nightly contains it's own firmware. If you flash cm nightly it will rewrite the oxygenos firmware.

You also apparent to you?

https://www.sendspace.com/file/p92byr
I remember having issues to install CM12.1 after trying OxygenOS ,I had to flash CM12 to overwrite OxygenOS firmware . So I hope there will be no issues installing next CM12.1 build
Any improvement with reception?

For me, I'd say that the signal strength is more stable than it is stronger... but I do feel it's a tad bit stronger. Could be placebo.
am i on oxygen's modem or cm12's? thankss!!

Based on this, Oxygen.

Flashed it and all working great so far. Anyone else noticed that the capacitive buttons light brighter? It's definitely noticeable in a dark room.
works fine here on cm12.1 04042015 unofficial!
for get the signal are necessary only 5 second! fastest than cm12 modem!
might be able to get away with changing the tz check script in the cm update zip if you've flashed this.
if youre using a custom build then might get your dev to change the tz version check to at least 1.09 rather than specific as the new is 1.39
Thank for sharing this modem.
I'm not sure if it's a placebo effect or the OxygenOS modem really works better.
Anyway it feels better and thanks for that.
Signal is def more stable!!
I just flashed it over the last nighlty blisspop http://downloads.blissroms.com/Blis...lissPop-v2.3-bacon-OFFICIAL-20150403-0935.zip - and it's working like a charm ...
Yeah the signal is more stable and faster to lock LTE here, and also 3G ... i can notice when i loose wifi and it changes to mobile data plan ... let's see if keeps like this.
Btw, everytime i flash new blisspop i should flash this modem / radio again !? right !?
flashed it over katinatez's Temasek rom.. so far no issues...

Camera blinking green on recording video after flashing LineageOS

Greetings,
On my S9+ (Exynos) camera blinking green when recording video after flashing custom ROM. On lower FPS (30) blinking slower. After first try of video recording camera still blinking until restarting app. What can I do?
Thank you in advance
Same thing is happening to me. I've used LOS 15.1 6/12 and 6/19 with the same problem. I updated to the latest stock ROM to get past the black camera problem, and now this. I don't see a fix for this listed in the next nightly either.

Thank you for your reply. I think that's only LineageOS's trouble, after flashing another ROM all is fine

This one https://forum.xda-developers.com/ga...elopment/g96xf-ard4-rooted-stock-rom-t3789326 after flashing my modem and bl was updated automatically
Before that I flashed https://forum.xda-developers.com/ga...ross-device-development/rom-lightrom-t3770243 but there after try to root I have camera issue with any camera app and stock. Maybe that's because of old bl and modem, so will try to flash it after ROM above
samsung s9 locked after reset ?
The problem also persists when using Carbon ROM, all Stock based ROMs I tried so far worked well with the Camera

Thanks for the link. Very helpful for the stock rooted ROM as well as the firmware and vendor flashes. I have gone to this for now as well, at least until folks report no issues with the camera in LOS. I use this for a camera more than a phone.

If you mean OEM Unlock, after first unlocking it wasn't lock again never except when you flash stock without any modification with multifile ROM.

Had the same problem. Now I use OpenCamera, and switched on the option to use Android-5-Camera2-Api.
Flickering doesn't occur anymore (in this app).

Installed Havoc, and Lineage, and ended up getting random reboots, and wifi issues.
Tried restoring the modem from oreo - didnt work
tried the fix that copied the wlan whatever file - didn't work either
tried the haumeakernel - nope...
how did you manage to get Android 10 working well? what am I missing here?

What's your variant? I've h930 and i used Los 17.1 for a very long time without any bugs or issues. Los 17.1 is the best and stable aosp rom i've ever tested.
