No WIFI when flashing back to stock

I have a strange problem.
When flashing back to stock from josalaito's repacked 4.4.2 rom, my wifi stop working.
It doesn't matter what firmware I flash:
Ive done it with:
Blur_Version.14.91.11.falcon_umts.Retail.en.DE
Blur_Version.14.71.8.falcon_umts.Retail.en.GB
Blur_Version.14.14.16.falcon_umts.Retail.en.US
and today with the new
Blur_Version.172.44.4.falcon_umts.Retail.en.US (4.4.2 Firmware)
there is no way to get wifi working on my device. (I can't turn it on in settings, also there is no MAC Address in settings.. )
The only rom where Wifi works is the repacked from josalaito.
Thanks for any help.

I have that same problem. :/ I tried that same rom and it looks like it deleted something? My phone is xt1032 GB retail 16gb model.

Have any of You get this problem solved?

[Bug][Solved] Can't make or receive calls when Wifi is enabled

For a week or two now, I've been having a strange issue, if my WiFi is on I can't call or people who try to call me get the notice that I'm unreachable.. SMS works fine. If I disable WiFi and use mobile internet everything's fine.
Don't know what triggered this?!
I don't have the time to investigate properly, so I thought I'd throw it on XDA..
I have flashed different Radios and a few 4.4.4 AOSP Roms, no luck..

I would flash the factory image and see if you still have the problem. If you do it's probably a hardware issue and I'd rma the device

when you receive this problem just go menu about and scroll down , you will see KTU84P or TU84M or other , so you need just to flash this one as same version i men if you cell KTU84P so use same to Radio file
and for wipe device , you do it or no , no problem because on my shop i reveice allot of phones so no have time to backup i just flash radio to preserve information for customer and 60% working and network 3G/LTE fixed if not fixed so you need to pass to second step (full flash )
for full flash i use : Factory Images "hammerhead" for Nexus 5 (GSM/LTE) from thsi site : https://developers.google.com/android/nexus/images
ask me any time if you still need help

Finally!
I managed to fix it.. W00t!!
I think I get it now, I tried reflashing factory image, KTU84P latest for me (I'm in Belgium), but that didn't work, then I thought about wat the stock rom was when it was shipped, I guessed it was the KOT49H build, so I kept the system image from KTU84P and flashed the radio image from the KOT49H build and voila! it worked.. So I think you have to flash the radio that the cellphone was originally shipped with..
Anywayzz I'll keep you posted how things end up when I flash other roms again.
Thanks again for the advice hitibiti !!

I know..

**BUMP**
So i've been f****** around some more and found out that I only experience the no calling during wifi bug using a modem version radio-hammerhead-m8974a-2.0.XX.X.XX I can always fix it again by flashing a previous version starting with 1.0.XX.X.XX this is all on stock rom on every android version. Running LRX21O now with radio 1.0.25.0.23
Still think this is some weird sh** and why only handfull of people have this?
So simply said: from radio v2 upwards (which came with 4.4.3 update) when wifi is enabled I can't make calls and people can't call me..

[Q] Wifi not working. Not a noob

Hi,
FIrstly I'd like to say I'm not noob. So please dont treat me like one and tell me to search the forum. I've already did it many times.
Secondly, I've tried MANY Roms. Like a lot. But all I want is something very stable. So I decided to use Stock.
I've tried these ROMs and some more I cant remember:
CM11
CM12
Honami
DextroDroid (wifi worked very well here.. just hated the nav bar and icon size. Coudn't live with it hahaha)
Clean 'n' Tweaked
Matrix
LiquidSmooth
Carbon
PAC-Man
And ALL Stock versions
Sometimes the wifi works after I reflash stock. But then I decide to do something else and the phone gets int oa bootloop and I have to reflash. Then the wifi is messed up again =(
Now I'm testing Kernels.
ThunderZap 4.1 and Extended Stock v6 are the best bets.
I would like to know if you guys have been through this too.
How to make the wifi work again and avoid bootloops?
I'm almost buying a new phone. I'm spending too many hours trying to fix Xperia L.

Ok, now the wifi doesn't work at all.
I've reflashed the stock roms in this order:
15.0.A.2.17
15.3.A.0.26
15.3.A.1.14
Wifi didn't work in any of them.
Flashed Extended Stock Kernel v6. Still no wifi.
Don't know what to do =(

Tried DextroDroid, now.
Didn't work either.
Don't know what to do anymore =(

Hi,
First flash stock ftf 15.3.A.1.14 stock firmware.
After that flash latest Thunderzap kernel and then flash LS milestone.
I never faced wifi issue with LS or CM11.
But only flash CM11 or LS on 1.14 fw not previous versions.

By latest TZ you mean 4.10 or 4.1 for JB ?

Tried with TZ 4.10
Didn't work..
I'm lost

Could make it work skipping the TZ step!
It was working perfectly!!
But then the phone suddenly rebooted and the wifi is not working anymore.
Bluetooth not working either.
I guess it's not a modules problem. Unless there are more people with the same problem.
Where can I find the wifi files in the internal memory? Can they be read ? I'll try changing them manually.

I mean... The same problem happens in every ROM.
Possibly with every Kernel.. Not sure.
What to do now?

Now I've tested:
ThunderZap 4.10
Phantom v17 for KK
None fixed the wifi =/
And yes.. I've wiped cache and Dalvik cache before flashing them.

Holy!!
I think it's hardware problem!!
I'll update you guys later.
Edit:
SOLVED
The hardware was a bit loose. I dissabled it, cleaned and put the screws very very tight.
Everything working =)

Strange Baseband; Strange problems

Hello everyone, this is my first post, after having read a lot in this forum already.
tl;dr: I flashed several ROMs onto the phone and always had the same problem: Connection to network goes away completely when mobile data is turned on. My baseband is S7652XXMA1 for which I cannot find a stock rom. Don't know what to do now.
Comprehensive description:
So I got a Samsung Galaxy S Duos (GT-S7652) and thought I flash some fancy ROM on it to gather some experience before I go and try with my main phone. So I installed TWRP, which went fine, then I flashed PMP Light ROM, because I read that would improve the performance and I liked the ROM.
The problem is, that as soon as I turn on the mobile data, the phone loses network. I double checked APN settings and tried the same SIM card with my other phone and those settings and everything works fine.
I tried to flash back Stock ROMs, but the problem stays the same.
Now I see two potential sources:
1. Baseband of my phone is S7652XXMA1 and I cannot find the right stock rom for this (although I tried some other Stock ROMs, because I thought they would change the baseband, which they did not)
2. When flashing process reaches the fat.bin (which I read contains the baseband) it gives me an error:
Code:
99%
100%
ERROR: Failed to confirm end of file transfer sequence!
ERROR: FAT upload failed!
Does anyone know how to proceed? Does anyone know where to get a Stock ROM for this Baseband S7562XXMA1? All help is much appreciated

Ok, telephony also doesn't work, if one tries it loses network just as in the mobile data case.
Has no one any ideas, how I could overwrite the Baseband?

Try cm11 with Hungarian baseband.
Is network working on phone properly?
You can also try to flash indian baseband, but keep a backup of old baseband

Wifi works without problems, for mobile network see my posts above.
I have not kept a backup, as I thought just reinstalling stock rom would bring me back to original.
Why do you recommend to flash Hungarian Baseband cm11, so far no baseband rom could overwrite my fat.bin, what does this do differently?

So far I was mostly trying various Stock ROMs and PMP Light Rom. Ok, I will try the Hungarian Baseband cm, if that promises better results. I will report back if that worked.

CM11 gives good performance than stock rom for sure.

Hey, I managed to override the baseband with the Hungarian one through the zip from here: [CM11][GT-S7562] Samsung Galaxy S Duos Kitkat 4.4.4
The problems are still the same. I tried to install the cm11 from the same thread (through TWRP), but I get an error (Updater process ended with ERROR: 7) telling me that I am trying to install on top of incompatible data. I tried doing a factory reset, but to no avail.
Right now I am on |DisContinued| COSMIC ROM | Version 2.5 |KitKat-Mod|Galaxy S Dous|Smooth|Fast|Stylish, which also is based on cm11.
I will try to flash some other ROM from PC, but I don't have much hope that will solve anything. Does anyone know where I could obtain a Stock ROM, that is compatible with Hungarian Baseband? There is a link in the Kitkat Thread above (http://d-h.st/do72), but it only gives me some exe-file instead of the tar.gz that I look for...

I don't think cosmic is based on cm11 its just kitkat themed stock.
Try to again download cm11, u will find a new experimental build on last pages.
U can find the stock firmware from this thread.

Its hosted at http://d-h.st... The only thing I can manage to get from there is a 7z1602.exe, which seems like a bad idea to execute. Can you download from there? If yes, maybe you could then upload it to a different file hoster, I would be very grateful.

Yes i tried to download stock Hungarian firmware from cm11 thread, it isn't working.
i reported it their.
Have you tried to download from here, download your country firmware - https://www.sammobile.com/firmwares/database/GT-S7562/
You will have to flash with odin , their are many good guides available for that on Google

I know that site, but they don't have the version for Hungarian Baseband. I tried some other stock roms from there though, but no success.

They provide flash file which can be used with odin through computer. It will install stock samsung firmware of your country, so it will make the whole phone new, don't forget to backup your data.

I started this Thread because that messed up my mobile network connection, so it is not "new". I need some firmware, that will work with my (now) Hungarian Baseband.

You say that you cant flash basebands through recovery, so now the best option is odin only, now i am out of ideas about for your problem

I was able to flash the hungarian baseband only, no other worked. Now I do need some ROM that works with that Baseband. I posted a request for a new link in the Thread, maybe I then can proceed and make some progress.

Just if anyone is still following this, I have managed to restore the network connection by using the Hungarian Stock ROM, which I finally managed to locate. If anyone needs it too, here is a link:

Suddenly no cellular connection anymore

Dear forum,
a few days ago my cellular connection (i can't connect to my provider) doesn't work anymore. Sometimes a day it works for a few minutes, but mostly not.
I have a Galaxy S4 with Lineage OS (was perfectly running) and there was no update when it stopped working.
Meanwhile i tried to wipe and flash the OS but the error is still there.
My sim card is working in other devices and other sims in my don't work too.
Thank you for your help
Mrluca

Flash stock rom via odin
if after you flashed stock rom via odin it still doesnt work it could be a hardware fault
To eliminate any software problems you must flash stock firmware via odin

Flashed the stock rom as you said, but the error is still there :/
Even when it displays that there is a connection, every call just stops after dialing
So i guess it is a hardware fault?
