Wifi issue on AOSP Roms

Hi guys,
I have had the s2,s3,galaxy nexus,original note and i am used to flashing and modifying,but i have a serious issue with the note 2.
The problem is whenever i flash AOSP rom(cm,aokp,pa) my wifi would not connect.It shows the name of the network and when i click conenct nothing happens.Flashing back TW rom fixes it,wifi works like a charm. I've done full wipes but it doesn't seem to resolve the issue.I tried different kernels,but that doesn't help either.
So I am stuck at TW roms and i hate that.Anyone has any ideas?

You can try options 2 and 3 from this thread.

Thanks for your reply,but i tried this and it didn't solve my problem.

Anyone?

I Have the same problem...

Not sure that it will help you but I read something yesterday about this issue.
The solution was to NOT restore your Google profile during first boot so you should full wipe and try again.

This actually has nothing to do with the problem.
After a few days I finally found the cause ,and therefore,a decision to the problem.
It is the bootloader from 4.3 sammy leaks.It seems that this new leaks(probably the reason being KNOX) cause malfunction of wifi in aosp roms.What i did was ODIN flash stock MG1 from sammobile .This brought back stock recovery so i had to flash TWRP again and it solved the issue for me.
Before that i had tried changing roms,kernels,recovery,modems and nothing worked so I am pretty sure it is the new 4.3 leaks bootloader.
Some people will say that it can\t be the issue because they are using 4.3 sammy and do not experience the same problem on aosp roms,but i think thats because they flash it through CMW ,which doesn't change bootloader,while flashing through ODIN does.

With my Note2 this is not the solution. I've tried everything. What you said, move file "pit" ..... but nothing. I can not connect wifi. The connection does not appear region Spain, and have opted to choose europe, but neither. I do not know to do. CM 10.1 also does not work WIFI. In Stock ROM or Custom ROM works fine fine, but in ROM CM 10.1, 10.2, AOKP don't work.

[Q] Installing rom(slimkat) from Stock 4.4.2

Hello. I've been flashing/installing customs roms all day..
I can't seem to solve my problem. Wi-fi wont connect in any of 4.4.x custom roms(slimkat,paranoid..etc)
however it works fine on 4.2.2, 4.4.2 stock and LRS rom
full packaged rom seems to be only solution for me.
heres what i did
My device came with 4.4.2.
I downgraded to 4.2.2
rooted
used loki/twrp package to install twrp 2.6.3.2
wiped data/cache/dalvik
installed custom rom
boots device fine but wifi wont connect(i do see list of wifi network)
tried following
higher version of twrp(s)
tried 4.2.2/4.4.2 flashable bootstacks
tried different type of roms from infected website
tried flashing custom roms after flashing 4.2.2 + 4.4.2 flashable stock roms
none seems to be working.
=( are there any other steps i need to do?
perhaps missing correct kernels?
thanks in advance.

What model gpad do you have? It looks like a v500. Sometimes a factory reset after ROM install helps. Does android settings show the WiFi MAC address?
If it does the kernel at least detects the WiFi hardware on a basic level.
I do know that slimkat after installing seems to require a reboot for things to settle. However as i recall that was for some of the sensors not wifi. Did you reboot after install?
Also did you set the WiFi region in the advanced part of the WiFi settings?

v500
did reset/reboot still doesnt work.
mac address/region information(changed to us/can/europe for test) is there.
i did notice that there is no bluetooth address however i did install many other custom rom.
this isn't the only rom with the problem.

What did you use to downgrade to 4.2.2?

[Q] Battery drainage because of mobile data

Hi Guys,
I am new to this forum and got a small question. My girlfriend has an Oppo Find 7a. You guys probably know that the stock ROM is ColorOS. In my opinion it's crappy as hell, lots of bugs and issues, so I decided to flash Dirty Unicorns 5.02 on it. I did that yesterday and all is working fine so far, except that the battery drained from 100% to 64% last night (in 8 hours). See the photos attached. According to the photos it seems clear that the issue is the mobile data usage. I've checked the settings and it seems mobile data loses connection, connects again and loses connection everytime. Probably this is the cause of the battery drainage. Somewhere on this forum I read something about flashing Alucard 1.1a kernel on it to fix this issue. I want to try this in the evening, but does anyone know the correct type of this kernel as I found different alucard 1.1a download links?

Can someone please help me out with this? Yesterday evening I just flashed the Alucard 1.1a kernel via the custom recovery. I also removed dalvik/cache and rebooted after that. The Oppo boot logo appeared, but it stayed like this for 20 minutes. I'm not sure if I have to wait any longer to make it work or if the phone is just not booting up anymore with this kernel. Any advice?

before flashing DU did you flash proper modem and trustzone firmware?

Nope, actually I didn't. I wasn't aware of the fact that this was necessary. I had ColorOS 2.0.0i on it and flashed DU directly on it.
Can you maybe tell me what the proper modem and trustzone firmware is? And can these still be installed now even if DU is already flashed on it?

well you can do a clean flash again but this time you have to follow this for how and why to flash modem and TZ firmware:

So, one more thing If I may ask. What is the best thing to do from here on:
1. Flash modem, flash firmware, flash DU (directly over the DU rom that is installed now without doing a factory reset / wipe)
2. Flash modem, flash firmware, perform a factory reset / full wipe and then flash DU.
And will the newly flashed modem and firmware stay on the phone when i do a full wipe?

do a clean wipe, then flash modem, then firmware (in bootloader) and then rom along with gapps.

It's been a few weeks, but I finally had the time to do this. I've done a full wipe in TWRP and then flashed the modem on it. This showed succesful. It took about 10 minutes before the phone booted up afterwards. After that all seemed fine, so i've put the phone in bootloader via a command in cmd and installed the firmware. This also went succesful, but now I still have the same issues on the Oppo regarding the provider issue as mentioned earlier. The data connection is still being lost very often and it still seems to be draining battery (although less than before). Is there something else I can do to fix this ?

If you have recently done a clean install, give it some time to settle down. For Data connection issue, make sure to check your APN and also try a different sim or this sim in some other phone, could be signal reception issue.

I will give the battery thing some time to settle down then. About the data connection issue; This was not an issue on coloros, but I will check apn and try another sim. Thanks again!

I've changed the APN settings, as they stood on some kind of roaming setting. It's now been set to live.vodafone and seems to be functioning better already . If I still run into some issues I'll let it know. Thanks for helping me out

Hi
XDA newbie, still learning where everything is! I posted this question in the general help thread but got no replies, then I found this section so please pardon the repost
I have a rooted Galaxy Note 2 N7105 (t0lte I think) running Samsung Stock software 4.4.2. I have previously installed various version of CyanogenMod and Ditto Note, and somewhere along the line have lost my GPS functionality! Running CWM recover, not sure what version off the top of my head. The exact issue is that when I turn GPS on, it shows the "searching" symbol endlessly and will not lock to any satellites.
I have tried reflashing the modem and every GPS fix app that I've seen suggested on forums, and it still will not lock my location by GPS. Power saving (wi-fi and mobile network) location still works.
From my research, I believe the NV Rebuild method (listed here http://forum.xda-developers.com/showthread.php?t=2211690) is what I need to do in order to fix the problem. However when I access the hidden dialer menu and select NV Rebuild it tells me "Not Support in Custom Binary!" Other people have had this issue and posted asking for help in the thread, but nobody replied or helped them.
As I mentioned, I am running stock Samsung software, not a custom ROM. The phone is rooted, and I do have a few Xposed modules installed. I also used Triangle Away and my bootloader shows the device status as Samsung Official. It also showed Official in settings when I tried to run the NV Rebuild. As far as the information went, this should be all I needed to make NV Rebuild work, but it still gave the custom binary error.
Does anyone have any suggestions for how to get around this? Do I need to completely unroot my phone and reflash a vanilla copy of Samsung 4.4.2 before it will work, or is there a workaround to make the service menu read my phone as official and run the NV Rebuild?
Any thoughts or ideas would be HUGELY appreciated as this issue has been driving me mental! (Please let me know if you need further information and I will try to provide it ASAP)
Thanks in advance!

Try lineageOS 14.1. My GPS was dead after going back to kitkat after lineage. NV rebuild also not support in custom binary. Found the solution here https://forum.xda-developers.com/ga...nt-n7105/rom-lineageos-n7105-t3538310/page136
From lineage I did only a format(not wipe or factory reset, I dont know what is the difference) in TWRP 3.2.3 and flashed zip of the omnirom kitkat, and GPS was working, then format and flashed official FTM ROM. Maybe not need to go via omnirom, for me it was clear that kitkat is not getting the fix and it was easier to flash a zip kitkat than an image from Odin.

Your solution gains my interest. I am using GT-N7105 too. The road of Roms I have been through is Lineage 14.1 -> Resurrection Remix 5.8.5 -> Stock 4.4.2
When I went back to the Stock rom, GPS totally unable to detect any satellite using any GPS tools app. IMEI blank but Baseband is still there, the weird thing is the phone network signal works without issue. :angel:
Have been trying many ways to fix GPS including reflash stock rom but still failed. I went back to resurrection remix 5.8.5 and GPS works without issue but IMEI is still blank.
Any recommended omni rom as you mentioned? and what is official FTM rom? A stock rom?
