[Galaxy S II General] iovaniorgovan:
Hi guys,

It is a long time since I've been planing to write here, so here is my story.

I'm a big S2 fan, probably as most of you here. Since May 2011, I had 3 x i9100, and currently I use two of them on which I test, install, swap around different official and custom roms.

For about one year, I had no signal issues, but approximately after the official ICS introduction for i9100, I started experiencing different signal interruptions. I use them both on the Orange network in Romania.

At first, I found the phone out of network on "Emergency calls only". It was about 6 moths ago and I was running Omega 15 and I described accurately here.

I thought it was a SIM card issue. I changed it with a brand new one but the problem won't go away. Then I started changing modems, but as the OP on this thread said, they were made by various people and we don't have the certainty of it's content.

With time, I saw different signal interruptions, even if I was in the middle of the city with full signal:

-while speaking on the phone, the call was interrupted and the phone leaved the network for about half a minute. This was very very annoying.

-while in standby, the phone leaves the network and it sits in "emergency calls only" and only rejoins the network after a reboot.

-while in standby, the phone leaves the network, goes to "emergency calls only" and rejoins the network after about 20 sec.

-while in standby, the phone leaves the network, shows "no signal" symbol and rejoins the network after about 20 sec.

I had many missed called from my friends and family. Some told me to throw away this brick and move to dumb nokia phone which never fails.

These signal interruption happen often, for half a year now and I tried many official and custom roms (omega, neat, wanam), ICS and even the latest JB.

All of them had problems with the signal at some point, on both i9100. The problems didn't looked identical on both. For example, with BBS I monitored how much time these phones spent without a valid data signal, and it varied from 1 to 30 min per 8 hours testing time (overnight).

I have a few prerequisites: I'm a jkay fan. Jkay's framework is a that holds many improvements to the ICS firmware, like custom lock screen and taskbar, custom actions for volume buttons, many many other features that I love

- Jkay Samsung Galaxy S II I9100 > Galaxy S II Original Android Development > [MOD][ICS] JKay Deluxe framework 14.1 - XWLPI/G/F/D/9/8/7,XXLPW/S, UHLPS [2012-7-19]

Unfortunately, the author, Jkay, only made it available for a few versions of ICS 4.0.3, and I'm sticking with what it is said to be the best of them - XWLPI.

And out of all the XWLPI's out there (official and custom), I am running now with the one modded by Salesale: Neat Rom Lite, as it was recommended to be a stable and fast rom.

This was the official rom who Salesale modified:

GT-I9100 - Germany

PDA: I9100XWLPI

CSC: I9100DBTLP6

Version: 4.0.3

Date: 2012-06-18

Please tell me if, in order to fix my issues, this thinking is correct:

Since my SIM card is on Orange Ro, I need to download and extract the files from an Orange Ro firmware. And since I'm using ICS 403 XWLPI, I should go for a close match, like:

Romania (Orange)	2012 May	Android 4.0.3

PDA: I9100BVLPD

CSC: I9100OROLPB

Version: 4.0.3

Date: 2012-05-25

The I should reap the heart out of this rom and extract:

1. /system/lib/libril.so

2. /system/lib/libsec-ril.so

3. /system/lib/libsecril-client.so

4. /system/lib/libsecril-client-sap.so(4.0.4+) -- not the case for 4.0.3

5. /system/bin/drexe

And then replace them into my device, so is this correct?
