[Q] Unstable signal after ROM flash? - Galaxy S III Q&A, Help & Troubleshooting

Hello
Yesterday I tried flashing my GT-I9300 with MIUI 4.9.20 rom with Danish language..
But I have some problems with the new rom.. My wifi and phone signal seems to have become unstable, when looking at the signal strength it jumps between full, low and no signal..
Don't know much about flashing roms, last time I did it was about year ago..
Looking at the forum, I see people talk about flashing modems etc. on the mobile.. Do I need to do this??
Anybody know how I can fix this?
If you need more information please ask..

ROM suggestion to use in Turkey

Hi all,
I have an AT&T fuze that I use on Turkcell here in Turkey. This is a GSM 900 network. At the moment we don't have 3G.
My question:
Which of the raphael roms (6.5 based preferred) would you suggest for best network performance on the 900mhz and also in terms of battery life.
At the present I am getting like 1.5 days or so (the phone is never swithced off) with about 30-40 minutes of talk time, about 10 minutes of gps and almost no wifi use. I feel that is a rather short time for the battery.
Thanks
Hi there,
I think that it's most a radio problem than a ROM problem.
Try to change your Radio version and see what happens.
(Pros answer may be better than mine, so wait for them...)

Try different radios, it's a matter of luck ;-) I've just flashed 1.14.25.35, will keep you posted about the mileage.

[Q] WiFi Woes; Would love some help. [Already did thorough searching/troubleshooting]

So guys, I've been having some issues with WiFi on my S3 and I resort to posting here only after trying everything else that I can think of. I'm well aware of the rules regarding noobs on XDA and I hope that I haven't broken any of them.
The Problem: All networks are detected within normal range, but attempting to connect to them results in a "Saved, secured/open" result, while not connecting. Sometimes, by spamming the connect button, I can connect to a network for a few minutes, but will not get a working internet connection, just WLAN connection. Finally, when anything related to WiFi is left on, I experience extreme battery drain, surpassing even screen use in battery consumption.
What I've done:
Tried CM10.1 and CM10.2 AOSP ROMS, as well as Omni 4.4 ROMs.
Did some searching, tried various Stock based ROMs, same issue present.
Searched some more, tried flashing a stock ROM through Odin..same issue. (Although I did not leave it long enough to test battery drain.)
Tried that wifi patch for custom roms floating around, makes no difference.
Deleted files (on a fresh install) in the /data/ folders as suggested in several posts. No help.
Tried flashing a few modems, one did in fact seem to help my mobile data signal, but no luck for WiFi.
Tried the AOSP roms above with 1-2 different kernels.
Hit phone lightly against wall.
Remove MicroSD card.
I cannot remember exactly what happened when I noticed the issue because it was during the Christmas celebrations and I was staying at family. I chalked it up to their possibly shoddy router and made a mental note to reflash my rom when I got home, which is when I realised it wouldn't be such a simple fix.
I'm already preparing to buy a new phone (thinking Xperia Z), but I decided to post here as a last resort. I know this has been asked a lot, but I decided to post because I experience the same issue on the stock ROM, a symptom not listed in any of the reported cases posted.
Thank you guys for your help, I'd love to just be able to fix this issue and be done with it rather than shell out for a new phone. Hope everyone has a happy new year!

[Q] Poor signal

Hi guys
I got a poor signal after I used is rom :
DocDroid_Extreme_V1.3_XXAMI4
I liked this rom so much but the signal is a big issue to me
so plz help me
I realy don't know what shoud I do
Signal is not an issue of the ROM. Try changing your baseband to one of your region.

Best firmware?

I'm currently looking for the best firmware for kenzo in terms of signal, currently I'm running 6.12.22 and it's not bad, although sometimes signal is pretty low. I tried also newest firmware from one of the threads but it was even worse, a lot of time with no signal or no mobile data. So what firmware are you guys using?
