I have tried reboot and reflashing..seems like custom ROMs simply wont detect my SIM. The only ROM that detects my SIM is the latest stock ROM. So every time I will start flashing custom ROM from that point, and once I boot into custom ROM its either SIM wont get detected or IMEI gets unknown.

I tried this, at working custom ROM I use TWRP backup /EFS. Flashed custom ROM. IMEI unknown. Restore the /EFS backup made earlier. But still to no success.

Are you sure u have the correct recovery? Last time i had this problem,, i accidentally download twrp for another type of s3. Yet make my sim unusable with custom rom

But even when I am on stock ROM I am using TWRP 2.8.6 and the SIM works. Is there any other reason why the SIM only works on stock ROM?

For which device? Are u sure it is for i9300? As for me. Last time i flash stock with odin and then flash recovery. Sim still working but after i flash custom rom with that recovery, error cant detect sim appear, and imei unknown

I just flashed aD3.1 on my son's S3 - no issue with IMEI.

This is the stock ROM I9300XXUGML3_I9300OLBGML3_I9300DXUGMK1_HOME.tar.md5 that works. So in the end how do you fix the issue? what is the root cause of your problem exactly?

In fact when I flashed AD3.1 to my i9300 my IMEI and baseband are correct but somehow I got the No service error.

I fix it by changing the recovery. U can try it.

err sorry, what does AD stand for?

Using it right now. So much better than build12 cm12.1. Expect ad3.1.1 to come next week as mentioned by justarchi.

Yes indeed - this AD 3.1 is so much better vs whatever build he has done b4.

ok tq

Ok I'll try it..which recovery are you using BTW. I was using https://dl.twrp.me/i9300/twrp-2.8.6.1-i9300.tar.html earlier.

used recovery TWRP that packed by Naveed
or the new philz recovery

How is it better compared to the previous build? any screenshot?

All i can remember comparing to almost stock rom by AD which was last year's rom.

LED bro...I need ur help...I flashed this AD v3.1...impressed with its performance..but there's something I can't fix myself after reading xda forum...hope you can help me out hahaha..

I would like to know if I can remove the google search? which is sticky on screen.. and how can I change my ring tone and notification tone? without stock media player seem not possible to change add custom ringtone?

Google search can't be removed - you have to untick it in aroma installer.
For adding ringtone - install root explorer - launch it - go to system - media - notification - ringtone.
I suggest you rename those whatever ringtones you have B4 copying to that folder.
And reboot.

Ok you won't believe this. Originally I have given up but I saw your reply so I turned on my i9300 to try your fix, but without even trying your fix, it works...SIM is detected. I have tried reboot, power off for few hours the other day but not a damn thing works. Now it works without any fix...so thanks guys.

BTW, although it works now (and I have made a full nandroid backup) but when I flashed the ROM last time, I untick Xposed just to save that lil bit amount of time. Now I wanna install Xposed manually as I was too afraid to reflash it again. I just wanna ask the Xposed originally included in AD3.1, is it the same with the one here http://forum.xda-developers.com/xposed/sup...xposed-t3072979 ? I wanna try to follow the instructions there.
