i have heard that it is due to kernel.
the hardware and software need a kernel to communicate with eachother.when u flash a rom,the versions of both are mismatched.
try flashing the appropriate kernel too,matching with the rom.
what kernel?where to find it?i am sorry i dont know this,
just want to give u idea ,of which nature your problem is .
hope you find what you need.

[Q] - Ruined for all other ROMs?

So I have a little bit of a strange issue.
I had flashed the AOKP Milestone 5 on my TF, and although I managed to fix the CWM bootloop, it doesn't appear I'm able to install any other ROM.
Since I've flashed it, any other ROM I attempt to flash either fails to complete it's first boot (watched a few different ones try for hours yesterday) or wifi will not turn on. The wifi issue is also present in my backup from stock.
Perhaps for the ROMs that are booting for me there is a different kernel I may have better luck with? Thoughts, anyone?

What recovery are you using? might pay to try another (Recommended: http://forum.xda-developers.com/showthread.php?t=1759452)
You may want to obtain a kernel compatible with the ROM you want to try and flash both the ROM and kernel at the same time. The wrong kernel could definitely cause both the booting problems and the wifi not turning on.
I think about a kernel problem too, go to your ROM thread and you'll see the best kernel to flash with it...

[Q] What is the best Kernel for this issue... (xt925)

I flashed it with this TWRP version just fine:
http://forum.xda-developers.com/showthread.php?t=2476238
I know it is an old build - I tried to update to the latest 2.7.xxx but it has been giving me constant errors.. It flashes perfectly fine on my XT925 with this version of TWRP.
Thanks for the help, i tried twrp, i flashed miui but still crashing every 2min...

Interesting.. I never had that happen.. I wouldn't say it is a fluid and ultra stable experience, but can't say I had any FCs or anything other than random freezes on the gallery....
What caused me a lot of performance issues was the Xiaomi download engine and the rom felt overall much more resonsive and fluent after I disabled it.. maybe you want to try that.. just go to the "Downloads" app => Settings and disable the Xiaomi Donwload engine/manager.
It will warn you about bad internet speeds.. just ignore, the opposite is the case =)
good luck
Hum, I already tried that i was thinking my problem was solved but 15min later, crash, crash and crash ...

[Q] XT925 CM-Nightly 2014.10.28 - Not getting any GPS-Fix

Hi,
maybe anyone has some suggestions...i'm not getting any GPS Fix...i've flashed the Stock 4.4.2 and flashed the 10.28 Nightly.
I'm not getting any GPS-Fix. I've tried probably anything i can think of: GPS-Status Apps, Sygic, Google Maps and other Stuff...
A-GPS is working, but also not very well.
Hopefully someone can put me in the right direction...

Hi David. You have to flash your phone back the stock firmware. And turn on your GPS and Wifi manually on the Settings. While your phone is on stock, run your GPS apps and teu to obtain the signals. DO NOT turn off your GPS and WiFi settings. Now you can flash your phone to any ROMs.
Only stock firmware have ability to activate the GPS hardware sensor.
Hi saranay
thanks for your reply. Right now i'm a bit confused, because i never actually did that with the JBBL Cyanogenmod Versions. Or at least, i never did that on purpose...
Do you know, if i can flash the stock Rom with CWM/TWRP? Or do i have to use RSD Lite? I know that i have to use Deodexed Roms on a Samsung Galaxy...probably the same with the Razr HD?

I don't think you can flash sbf stock files on CWM/TWRP, but only on Fastboot Mode.
But you can try de/odexed files for Razr HD to flash back to stock to see if you can get your GPS and Wifi to work first.
From my experience. I just used RSD Lite to get a fresh start.

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:
