Wifi problems after installing new rom.

I installed a newer version of Ultimate HD for the Sony Xperia Arc/s, Link here.
And after that my Wifi didn't work anymore, so I searched around for hours and eventually updated my kernel which was Lupus v10, and now is v16 link
It says in the thread "Wifi is build in NO NEED for WIFI MODULES.ZIP" So I flashed that and then installed Ultimate HD again and still have no wifi now, it just keeps saying Connecting..
I would be very grateful if one of you guys can help me out!, thanks.
Sander.

That seems like something to do with some bug in ROM...
Q 4: My WiFi doesn't work. What can I do?
A: Flash WiFi Modules for your Kernel. If you are on stock kernel, reflash stock WiFi Modules. If you use Lupus, reflash the kernel and make sure you have a few mb left on the /system partition. If that, doesn't work, reflash the ROM and Check MD5 Sums.

Reflash back the stock ROM and see if WiFi works.. if it works, you better flash some other custom rom rather than This,....

XT925 - Wifi not working after Custom Rom install (but bluetooth works?)

So I'm new to rooting and flashing custom roms on android devices. This also shows that I'm new because I forgot to make a backup of my stock system before moving forward, hence this problem.
So I currently have CM 10.2 flashed on my phone and so far I can't get the wifi to work. My bluetooth works perfectly fine (I've read that if one fails usually the other should too), so I don't know what to do.
At this point I'm sure i'm stuck because I've flashed a few different roms already to see if i can fix it (10.0, 10.1, 10.2, and hacker's aosp 4.4) but the wifi isn't working in either so I stuck to the rom that had the fewest bugs.
What's weird was that it was working when I had 4.4 flashed, but when i found it too buggy and flashed CM 10.2, now it doesn't work.
Anyone else have this problem? I guess I can live with it for a while until maybe I purchase a new phone.
Thanks

Did you flash 10.2 directly over 4.4 without wiping system data and both caches?

The first time, no. I thought I may have installed 4.4 incorrectly so after installing 10.2 i tried flashing 4.4 again, but I did wipe the caches, system, data and dalvik caches the second time going back after reading in this forum how to flash over a custom rom. But then seeing that the bugs were still there, i wiped again and went back to 10.2 and I've been there for a day now.

Missed Wifi
I'm facing the same trouble , same conditions.

[Q] GSM support for alien rom on xperia J

[Q] Is there any way to get GSM network to work on cyanogen based Alien rom, in xperia j?
I just rooted my Xperia J 4.1.2 (.31) yesterday and went ahead with AVD which supposed to be based on stock xperia rom. But unfortunately its was a bit buggy. SystemUI.apk suddenly stops working and many apps kept crashing on me .. few other roms like slim were asking to be downgraded to ICS which i dont want to... then came Alien rom to my rescue. this rom is really clean not to mention the Acid Audio ENgine and stuff ...T____T I so badly want to keep this rom its ****ing perfect..!!! if only if the GSM would work, which while installing i didn't know that no cyanogenmod 10 based rom has GSM support !
Now i'm whining here because i just want someone more knowledgeable than me to give me the confirmation that that i have absolutely no other choice, other than going back to the AVD. LIke the GSM fix for the ICS baseband is there positively NOTHING out there for JB :crying:

You need to downgrade to ics first, then flash any cm10 based rom, or gsm.will not work.

just one more doubt...

getting out of alien rom and reinstalling AVD i screwd up and soft bricked my phone.
SO i had to use a pc to reflash the stock JB. BUt that has locked the bootloader again coz the PC companion can detect my phone again.
so just need to confirm certain things...
SO if i flash stock ICS then i will have to unlock my bootloader again right...? I presume i will have to root my phone too all over again... ? before installing the rom ?

PLease HELP!!!
Ok this is sooo irritating...!!! T____T
I flashed my phone with 4.0.4 ICS, st26i_11.0.a.3.18_global.ftf form Matej X's 4shared folder.
http://www.4shared.com/folder/25Mb7Dws/Xperia_J.html
the ST26i_11.0.A.7.5_CE.ftf from that folder when put into firmwares folder of flashtools, doesn't even show up !!!
i figured to root st26i_11.0.a.3.18_global.ftf from this guide http://http://forum.xda-developers.com/showthread.php?t=2033114&highlight=st26i+root+ics
but not inspite of downgrading to ics, when i installed MIUI5 rom i'm i'm getting no simcard ad hense GSM is not working all manually scanned networks are shown as "UNKNOWN" !
Now i have flashed back to stock ICS rom...
when i flast the stock rom using flashtool the simlock.ta file gets ignored. what's up with that, wherever i have read about its not supposed to be a issue...
Can someone help me this is really getting frustrating....
Can some one help me find the link for ST26i_11.0.A.7.5_CE.ftf ICS stock rom which will be detected by flashtool...
MIUI5 was really nice, I would like to use it. Its based on cyanogenmod10 fxp 226 ... My issue with that is i use the instruction here to install it, but its condusing.
https://sites.google.com/site/projectfreexperia/download/howto-install
It says "6.Wipe device
from cm9 device wipe is necessary only at first flash or when you switch cm version
!!! if after boot you experience ForceClose then is recomended to reboot to recovery and wipe device
7.Partition format
is not recomended to format your partitions unless you are advised to do otherwise"
Now in CWM what do i have to wipe...???
There are too many options to wipe....
1. wipe data/factory rest
2. wipe catch partition
Under advanced
Wipe delvic catch ...
Which and all am i supposed to wipe ?
Please bare with me guys i'm at my witt's end here...T____T
I just want one CM 10 based rom working for me... That's all ...

Here's the thing mate, AlienRom works perfectly fine for me. Just flash over stock ICS and Not JB and select Use 2G network on settings. Give it another try , oh and I highly discourage MIUI, it may look pretty but it is lag as hell. Browser takes sooo long to load and so lag

Hey Racer X,
I was thinking about the same thing... Alien rom is the only rom where i encoutered absolutely "0" lag, Brilliant work there man thanks a lot.
Would it be possible to flash it directly on rooted 11.0.a.3.18 ICS because i'm not able to root ST26i_11.0.A.7.5_CE.ftf with any tutorial here...
SO far i have tried this guide http://forum.xda-developers.com/showthread.php?t=2071817
and the other option being flashing to stock 11.0.A.7.5 and using Unlockroot.exe
But windows won't even detect the exe file and Google chrome's calling it a malicious file and won't let me download it .
SO i have sort of hit a roadblock with 11.0.a.7.5
So i was hoping i can flash alien rom straight on rooted 11.0.a.3.18 ICS, which i rooted with this guide http://forum.xda-developers.com/showthread.php?t=2033114&highlight=st26i+root+ics

Omg...!!! I did it ... :d
OMG... I just went ahead and did it... this is sooo f****** AWWWWSOME...!!!
Now i have Alien rom with GSM WORKING !!!:good:
I didn't even go for 7.5 i just stuck with .18 and went to alien rom 4.1.2
BTW can i keep the cyanogenmod upates setting to weekly or should i keep it at manual/???
I don't want to loose the gms connection just coz it updated on its own ... ?
What do you think ?

[Q] Anyone succeed with GPS with custom rom

Hi all,
Did anyone able to use gps with custom rom ( I would say CM base). I research and try everything that's I could find here but not success.
Every time I do clean wipe everything including a internal storage. So that will nothing left behind.
I know that stock is work fine with gps. some said that install and replace stock but I have no idea that what file will left in our device when we delete all.

Always had the same problem when running Paranoid Android (not tried other ROMs). Had to return to stock, where GPS runs fine. Would also love to kknow how people have got it functioning.

I am trying too. I modified gps.conf files, tried some workarounds mentioned in cm11 thread like restoring GPS Status backup from stock with titanium so far with no success. Some people say that it works but it doesn't on mine whatever I do.

I run on CM and I don't have any problem. Everything works fine with gps and I didn't use any fix or something similar.
I'm on CM 11-20140627 and I have 1032 phone.

Interesting, why does it work on some while it doesn't on others? Maybe some variants are having problems...
I have xt1033 asia version.

Which recovery did you use?

CWM

As I wonder is about library missing or some partition need from stock ?

I've also been using the micro gapps package, would this matter?

I had problems with Paranoid Android and GPS too... If anyone know something about that, please comment!

I am having he same problem on XT1032 running Carbon ROM. GPS worked fine on stock, no signal with Carbon.
I found many answers saying to flash stock and then reflash custom ROM. I will try it, but I wonder, how does this help? Isn't the phone restoring the whole system? Do I have to keep the gps.conf from stock?

I've read in some CM thread on here you need to flash stock ROM then enable GPS and get a lock. Once you've done that then flash your custom rom. Sounds STUPID and dosent make sense I know, but a lot of people say this is how they got it to work.
EDIT: I can confirm. I've just flashed stock 4.4.4 and played around with google maps. Flashed CM11 nightly and my GPS is now working ok

Did you wipe anything, like Dalvik, Cache and Data, or you just flashed it over?

Sorry people, I was so happy to have my phone back working, I forgot to write it back here.
Yes it worked indeed, all I did was flashing back the stock, going outside to have a gps lock with gmaps, then re-flashing back the Carbon. I also kept a copy of the gps.conf, but I never needed it, the GPS got a fix quickly. Working fine so far, it only takes some tens of seconds to fix, from time to time.
I can't remember if I also did all the wiping, I think I didn't, but I made so many trials in a couple days, I am not sure.
Thanks a lot guys!

Yes, this worked for me too on PA.
I couldn't even see a single sat (it wasn't just a lock problem). No matter with gps patch, gpx fix app, or gps.conf I used.
What I did?: Back to stock, lock GPS, flash again the custom ROM (but don't wipe /system!).
Good luck on that guys, it should work for you too.

GPS works fine on this unofficial CM11 rom for me. Stable daily driver rom for me, YMMV.
General advice is to:
- make sure you get a GPS lock on stock rom first
- flash CM11 (or other custom rom)
There may not be a file left on the device. it may just be that stock contains the code to initialize the GPS functionality on the SoC or chipset firmware. Whatever, it works...

WI-FI and Bluetooth is not working!

Hello! People please help. I'm not working WI FI and Bluetooth. He rarely worked after a successful restart on cyclic sink firmware 4.2.2. I'm sick of this, I decided to reboot and flash it on a stable firmware version 2.17. But why is the drain is not working 2.17 NFC WI fi Bluetooth. Then again I pierced it at 1.12, 1.14, 1.17. But there again repeated cyclic restart, but it is not working WI FI Bluetooth, NFC for work. I can not understand the smartphone fully working, why stop vayfay and bluetooth does not work? Read all forums and many of the same problem with not working Wifi and Bluetooth. Prompt, whether there is a solution?:смущенный: Smart SONY XPERIA L

I couldn't understand the question clearly .
Could explain it to me??!
If the WiFi didn't work after flashing the latest firmware I think you should Check the ftf file maybe it's not for c2105 (or you mobile model) COZ I read that the different between these two devices is just networking, So get the suitable one for your device model(if this was the question)

At first everything was working fine in original firmware ,
Even after flashing cm12.1 everything was fine,
once updated to cm13 later there is a problem of wifi and bluetooth sometimes it works fine and at some point mobile will reboot by itself later on both wifi and bluetooth doesn't work (They cant be turned on)
I re flashed original firmware,
re flashed cm12.1,Even tried many roms (Thunderzap,Resurrection_Remix,Temasek) but still problem remains same.

Try this it may work:
First of all try to change the ftf file (download other one)
If didn't work flash this boot.IMG via fastboot on stock ROM just on stock ROM.
After flashing it flash the kernal and Fota kernal from the same ftf via flashtool .
As I told you flash it on stock ROM then flash the kernal and the fora kernal

Thanks to @Joel16 for the link
I mean by kernal the kernal in the ftf exclude everything while flashing in flashtool except the kernal and the fota kernal

I'm having the same issue. But it started out of nowhere, so I'm guessing its a hardware problem.
After it happened, I flashed almost every kind of ROM and Kernel around here. Nothing worked.
Also I flashed the official Sony's firmware for my country and it still not working.
Tried the PC Companion's repair function, didn't work too.
When I try to turn WIFI on, I get a "fail to load wifi driver" message at logcat.
I'm not new into flashing ROMs, so I'm almost sure it is not a system issue despite the error message I get.
