Please someone help me out regarding my AT&T gsm tab. It used to have 3G and voice b4 but after flashing gingerbread 2.3.3 all gone. Just flashed 2.3.6 base p1000xxjpz, build gingerbread. XWJQ9
Kernel 2.6.35.7 also not working no 3G no voice. Error MSG contact customer support. My phone carrier is AT&T with voice and unlimited data. I googled and xda'd the issue but can't find anything to resolve this issue. Thanks for the help in advance.

come on guys you can do that

what was your original modem baseband?
do you have a copy of it.
when you first flash gingerbread 2.3.3 which rom is it (stock or custom) and did it include a modem in the package?
how many AT&T modem have you tried?

no don't remember any thing about my stock rom but my first flash was roto rom and yes now i have tried lot of modems but nothing worked. Roto rom and modem worked for me but i dont know where is that link

googled and found roto jmi v2

Hi Tabing,
I use the JK3 modem, packet data enabled, auto, and the wap.cingular APN.
The only other possibility is the type of sim card you have. If it is a data only plan, then the APN is "BROADBAND".

Hey RC how are you? Thanks for the follow up. Can I use JK3 modem with jk5 rom? Right now I have jk5 build with i9000jk3 modem but as soon as I hit wifi network To connect tab restarts. Tab also restarts itself after the tab's screen timeout reached. I flashed 2.3.3 rom before but bcos of wifi and network not connecting easily I now go back to 2.2. Do you think downgrading made the restarting problem. Also my sim is both voice and data enabled with att

Thanks priyana

[Q] Omega ROM on I337M

I successfully flashed i9505 Omega ROM v7 on I337M (Canadian)
Everyhing works fine but the wifi. I can't seem to turn my wifi on.
Tried looking into it, something about flashing a kernel. So I tried but doesn't work...
Anybody else have same problem that can help me?

Did you manually add in your apn settings, because that rom does not add them automatically, and you said you flashed a different kernel, was it one for YOUR device...i337m kernel?
These 2 things will get you data and wifi for sure.
The Ax says good luck!

v11 on i337m
I didn't want to start a new topic as this one seems to be titled correctly and am hoping to keep XDA clean and getting all the Omega Rom and i337m questions in one place.
I installed Omega v11 on my i337m (Samsung s4) and the ROM worked perfectly however I was no longer able to bring up my IMEI number. When entering *#06# my phone would just show a black screen where the number should be shown. I of course got scared and ran around in circles for a while before calming down and flashing stock FIDO firmware. (phone was originally rogers, was unlocked and used on bell then sold to me) I rooted the phone, installed Omega and then had the issue with it not being able to show the IMEI.
Flashed Omega v11 for i9095
(also bought the omega files pro app because it's a bad ass ROM.) Hoping to go back to it but need to clear up this issue.
Any ideas on why this would happen?

[Q] - i9507: No service on KitKat - Can receive calls, can't dial (no service)

Hi Guys,
I'm from Australia and recently bought an Optus Galaxy S4 4G. Strangely, the model number is i9507. I double-checked this online and usually weird model numbers are just carrier-spin-offs. So I went ahead to root and flash just like you would with an International i9505.
So far no problems - 4.3.x PA rom works absolutely fine.
BUT:
I've tried some Kit Kat roms recently and they all flash fine but give me 'mobile network not available'. Strangely though, I can receive calls/text and talk on the phone, but when I try to dial or send text messages, I can't do it. My reception bar is completely empty as well.
WiFi is totally fine, just no data and mobile network
I've tried messing with the 'network operators' setting and if i select my carrier (I have a Vodafone sim) I'll get network reception until I turn off the screen and then my mobile network becomes unavailable again
Not sure what the problem is; modem? APN? or roms not suitable for my phone?
Current info:

I've been flashing for a while now but it's usually just basic stuff so you can probably tell I'm pretty amateur lol.
Any help is greatly appreciated!
Thanks =)

Hi Rich
As your baseband is quite out of sync with the firmware you are trying to run (MH2 is from 4.2.2 ,,, right?) I would suggest you change your baseband (modem) flashing an equivalent to the ROM firmware from here.
I've got yesterday the exactly same behaviour when finally and reluctantly I've added a data plan. I was running a successful low-baseband + high-firmware because was setted to "GSM Only" (try it ... will work flawless). When I've switched to LTE got what you've described in the face too . I've promptly updated my baseband and now all is fine :angel:
EDIT: please do nothing of the above described BEFORE taking a EFS backup with every tool you can find and preserving them in several highly fortified locations and 2 or 3 K7 Tapes too . Have an ODIN flashable copy of your MH2 baseband is advisable too.
Hope I've helped and please share your experience.
Nice regards.

Hey thanks for the reply! Helps heaps =)
While I still had those roms installed I did try flash a few modems within Odin, all failed though =S
Which one should I be flashing?
I believe I tried XXUFNA1 but the flash just doesn't go through
Does it make a difference which rom I flash the new modem from? I.e. flash when the new modem now or flash the new modem on the kitkat rom?
I'm currently using Pacman 4.3.1 since it's perfectly fine. Just can't wait to get on a KitKat rom though! haha

Hi Rich
Sorry, may be my fault, but quite didn't got your
You may proceed having the below as a rule of thumb:
Your baseband (modem) version should always match your ROM (firmware) version.
Failure to flash something is never good signal. As you have an i9507 (I own the 5) is very advisable to flash a modem built for your S4 flavour.
The above rule should apply to it too so, if the only modem available for the i9507 is the MH2 your firmware have to match or these issues reported will return.
Did you tested the "GSM Only" option to corroborate (or not) my hyphothesis? With this config, you should perceive no signal drops when waked. I know it isn't a viable operational mode but ... just for fun
Nice regards and keep sharing :laugh:

[Q] LG G2 D802T 3G after root?

Hi
There is a lot of information on various thread about this but nothing really makes it clear to me what I need to do to fix this issue. I'm posting as I'm sure I can't be the only Australian user with this issue.
I rooted my phone and am using a custom ROM, now I am unable to get 3G data. When my phone switches to 3G no data is sent or received.
My understanding is that this is a modem driver issue. But I'm unable to find any instruction on exactly how to fix this.
Android Version: 4.4.2
Kernel Version: KOT49I
Software Version: CloudyG3 2.0
Any help would be appreciated!

Its not a modem issue I thinks. Its band settings issue..
U have a custom ROM. What's ur default telephony network? In build.prop
*#*#4636#*#* what's the default settings? Its equal to default network. Also available in mobile networks as Set network mode.
If you change from the info command. Does settings sticks after reboot? If not then you have to edit build.prop

Galaxy S4 GT I9505 Modem Firmware

Hi All,
I am in a spot of bother. I am using a Galaxy S4 I9505 purchased from Scotland/United Kingdom (probably refurbished) in India. I have put latest Lineageos 14.1 (Android 7.1.2) on it, but phone's data connection has been giving me trouble ever since I started using it (when I flashed the default Samsung ROM with CM 11). Same goes for wifi connection. I would need to reset both mobile data & wifi connections on/off frequently to make them work. I installed some wifi analyser app, which kept on reporting dropping of wifi connection every now and then.
I managed to learn from the internet that I may need to upgrade the modem firmware of my phone to resolve the issue. Problem is, all the necessary information like country of origin, Product Code, CSC Code, Firmware CSC Code, CSC Country, PDA Version, CSC Version from Phone Info app are empty. How would I know which firmware version to flash ?
Baseband Version as of now is I9505XXUDMGG.
Please help. Thanks in advance.
