Try this modems from directory MODEMS FOR S221 : https://drive.google.com/folderview?id=0B2ORIgaV4iacOVpDTDcxYW4taDQ&usp=sharing
ROM S221 is KK - modems for JB not working, U must install only those from this directory (Modems for S221)

To reflash your ROM you will find a lot of tutorials in this forum. To know what is the problem, is to root and install custom recovery and change modems one by one till something is going on.

I have tried all modem versions for my p780 and they dont work properly.Is there a way to find out if it is a hardware problem by myself?I bought the phone from China and I live in Greece so I think it is going to be a long time I guess till it returns.So I d preffer to fix it on my own.

I think it may be hardware antena problem, because before U had excelent signal. Or try flash the same ROM and modem which U had before (when everything was OK) On Youtube is a video how ro repare hardware antena on P780 (it was russian video).

my device is gt-i9300
i use 4.2.2 firmware
base band i9300xxufme7
and kernel is 3.0.31-702147
but the problem starts when i had my phone root and the firmware it was 4.1.2
thanks for the reply
Do a mega wipe and flash a full stock 4.1.2 ROM and see if the problem still exists.
If yes then it's hardware.

yes. try as instructed above. (making you aware: XXUFME7 doesn't have a modem by default. it continues to use the modem you already have on your phone before flashing it. also it will show all the previous apps as you have just flashed an update.zip from recovery mode! it even shows the super user if you were rooted! so you need to wipe everything immediately after flashing ME7 from odin. if not: messaging app crashes. and the problems you are facing). good luck
:good:
finally i found the problem thanks for the help the problem it was that the sim card slot it was broken

we are in indonesia and you in malaysia haven't get the latest update, if you want we can use the latest modem from germany..
basically to instal modem is just put it in your external sd card and then flash it with philz_recovery or via odin

not always, but base on my experience mostly it because you had dirty flash without cleaning wipe at first flashing or if you have weak signal it because the modem not base on our region.

Good move Just make sure you backup everything and i mean everything efs data rom etc please also read the guides in the stickies if you have not done this before.
best kernel for i-9300 is the latest boeffla kernel dude, you can get it here http://boeffla.df-kunde.de/sgs3/boeffla-kernel/Test_jb43/
pick 5.4 beta 3, almost perfect for me, very fast and stable :good:

Most likely then it could be hardware related especially if it was working before.Have you tried on someone else's router to see if it connects ok to theirs? Have you tried changing router channels?

3G coverage in India is very bad and that is the highest possible reason. Do you get GSM signal to make and receive calls? Whenever I saw 'x' near the signal icon, the problem was IMEI lost or wrong Radio flash. Try retrieving your IMEIs using Mobile uncle if you have backed up them. Else try different Modems which is also explained with steps in one of the other thread in this Forum.

S820 dualsim chinese model no network after upgrade to 4.4.2

Hi all mighty forum members.
I've upgraded my S820, dualsim model, chinese version to AOSP_4-4-2 but lost network. Rooted of course.
I have tested all modem drivers suggested in forums, the suggestion to go with P780.v52,2013/11/06 didn't work either.
I have tested changeing IMEI to new one, set different IMEI to the sims, tested same IMEI to both sims, no luck. I also tested different simcard from different provider to rule out gsm/g3 issue, no good...
I'm a bit stuck here and would appreciate some hint to get throu this nightmare..
Al the best!

Do not ever change IMEI when you have IMEI ok and have no signal! Modem software is faulty!
Here are some modems for JellyBean and KitKat. You have there custom recovery TWRP too.
Good Luck.
Hi,
I've tested all of those modems for kitkat, no good, but the twrp makes life a bit easier when testing
What I can see it that some of the modems removes the imei after install, but easy to restore with mobileuncle.
Anyone else have any idea what to do or test?

What ROM did you used before the update ? Did you tried to use another ROM except AOSP ?
I think is a ROM problem !
It was the stock ROM I guess.. Didn't write down what version. I don't mind downgrade as long I get a working phone. Could anyone tip me of witch one I could use? That is a version known to be working.

Hi,
thanks for the files. I installed the 4.4.2 (s820_ROW_s221), twrp 2.7.1.1 and tested with all the modems but no luck what so ever.
I've tested moving the sim from 1:st to 2:nd, no luck, I installed the IMEI stated on the phone, only one and with same number on both, no luck.
Wifi, however, works well as before...
I'm a bit out of ideas and would appreciate some suggestions that not includes using the phone as door stop....
