Sorry for late testings, the university got me from balls in matters of time
I've done tests with NIGHTLIES.
I've been working with the April's 24th Nightly.
The installation steps that I did:
1- Wipe, full wipe. System, boot, data, cache, all those partitions, FULLY WIPED.
2- Flash the CM9 zip package.
3- Flash the GAPPS package (

4- Sign-in to my GAccount, sync and in the case of the Nightly, install aLogcat from GPlay.
5- Start testing!
The modem that I'm using is the KB5 one.
After every test, I did a reboot of the phone.
For the Nightly tests, the results with the SIM card IN are these:
First call: Good. Rebooted.
Second call: Fail. 9 secs connected with no sound, and then call ends. Rebooted.
Third call: Did a EFS restore in here. Same as second call. Rebooted.
Fourth call: Same as second call. Rebooted.
Fifth call: What the heck... same as second call. Did another call without rebooting the phone and it did connect. Rebooted.
Sixth call: Good. Rebooted.
With the SIM card OUT:
First call: Got out of service first. Tried again, call did connect. Rebooted.
Second call: Good. Rebooted.
Third call: Good. Rebooted.
Fourth call: Good. Rebooted.
Also, I don't know why, but every time that the phone boot up, I'd to wait around 2~3 mins to have signal. In one case, I also needed to restore a EFS backup, I got a wrong IMEI!
In none test case I'd signal down after calling, magic reboots, freezes, FC's, etc. It was like a simple not connected call, nothing more.
All the logcats have been sent via PM to protect some info that's confidential and is saved in those logcats.
I've not done any dumps with the Test Build. When I run the dumpstate command, at the 30 secs the phone freezes and it won't unfreeze. Tried many things, but hadn't luck. However, I got results that are like the Nightly ones, 60 % fails, 40 % good with SIM with six calls. Totally good results without SIM and another six calls.
Any question, extra info, or whatever, don't dude to post or PM for it!
