[Q] Data signal problem - Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help &

I am on PA Rom with Yanks Kernel, i have tried many roms on my i9305 , but i am facing a lot of issues with my data signal.
I have to restart my mobile to use internet.
3g internet is slow like 2g internet.
2g doesnt works at all . Most of the time even the normal signal bars go invisible.
What might be the issue ?
Do i need to flash other modem or something ?
Ps- I am from India.

So what happens with stock rom modem and CSC ???

It could be your modem/CSC. Have a look here. There is loads of info and flashable csc's

Somebody please help me out !!

Flash your original stock firmware .
Test and if it works leave well alone .
Or extract modem from the rom .

No signal after flashing

I flashed it with many firmwares..Big ****ing mistake :crying: . Now i need to know how to fix it , ergo i come here .
I'm in India so i think the baseband shouldn't be XXJVT . Help a brother out ?
What rom are you on?
If I understand you right, you flashed many roms and NOW don't have a signal any more?
Try flashing another kernel via odin, if that doesn't help I would wipe cache/data etc.

Its possible you are on the wrong Network, some network providers belong to the same group as such your phone may be getting signals from their sister network and not from the network your sim originates from
check menu> settings> wireless and network > mobile networks > and select the correct network , if its on another

Before doing something, make a nandroid backup & then flash this baseband.
I think that's not the problem
I think that's not the problem, should improve the signal reception, I've tried and I can only call at certain points in the city, out of town does not detect the network.
I tried XXAMg4, XXAMJ1

Yes, you're right. This is a known bug in maclaw's & oliver's roms, but maybe it works for him, nothing to lose, just need to try it.
I tried the XXAMG4 baseband but doesn't work...
I don't know where to download the XXAMJ1. Someone have the link?
kernel and baseband
No network/data bug still exists also for me, I use an S3 mini H3g with a WIND ITALIA SIM.
I've just tried to change my baseband with AMG4 nothing change, also now I've random reboot when I'm on GMS/WCDMA or GMS network :/

Yes, simply flash it & then reboot twice, because first time, phone will be very laggy
Read my FAQ (click on my signature) to see the latest baseband.

I asked this because I'm one of those who can't have signal working on Maclaw's works. (ITA H3G brand)
How do I backup things overwritten by this zip first?
