[Samsung Galaxy S II Plus] Maxiride:
I understand that maybe it is getting a bit of a mess so I thought a summary could help.

I always wipe Cache\Dalvik after doing any change, so even if I don't write it in every step, I always do it.

First Scenario

Stock firmware

Flashed latest TWRP recovery

Wrongly flashed 20141116 because in a hurry I thought the repo list was newest to oldest and I didn't read the filename ^^ and flashed GApps minimal edition and Bloatware- Phone\

NFC-Enabled SIM works

Flashed 20150330

without

wiping Data\System\Internal Storage - Phone works,

NFC-Enabled SIM don't work

Changed the SIM -> Removed NFC-Enabled and inserted a 128k old SIM - Phone works\

128k sim don't work

Flashed again 20141116 with wiping Data\System\Internal Storage - Phone\

NFC-Enabled SIM works

Since both NFC-Enabled SIM and 128k SIM didn't worked in the 20150330 I thought was something related to corrupted EFS partition, turns out EFS is completely fine.

Second Scenario

Flashed Stock firmware downloaded from Sammobile (I9105PXXUBNG1_I9105PITVBNG1_ITV) - Phone works,

128kSIM works

(the NFC-Enabled one was busy in my work phone which is my main number and I need to keep it available)

Flashed TWRP Recovery

Flashed 20150330 wiping Data\System\Internal Storage and flashed GApps minimal edition and Bloatware- Phone\

128k SIM works

Flashed SuperSU and I even managed to run smoothly Xposed Framework! =) - Done a Backup with TWRP (System\Data)

Flashed Resurrection Remix as suggested - Phone\

128k SIM works

Flashed the backup made with TWRP (Data\System) - Phone\

128k SIM works

This evening I had time to switch back the SIMs, removed the 128k and inserted the NFC-Enabled SIM - Phone works,

NFC-Enabled don't work

Switched back the SIMs, removed the NFC-Enabled SIM and inserted the 128k SIM - Phone works,

128k SIM don't work

Tried to flash the previous backup again - Nothing changed, both 128k and NFC-Enabled SIM doesn't work

Wiped Data\System\Internal Storage and flashed as a clean install the 20150330 - 128k SIM and NFC-Enabled SIM doesn't work. During the first boot setup the Cyanogenmod setup process notified about no SIM detected.

WIped Data\System\Internal Storage and flashed the 20141116 as a clean install -

128k and NFC-Enabled SIM both works

Wiped Data\System\Internal Storage and flashed Resurrection Remix 20150409 - Phone works,

NFC-Enabled SIM doesn't work

The mere action of inserting the NFC SIM (to just discover that it doesn't work) and then inserting back the 128k SIM corrupted something and made it don't work again... Between the two state 128k\NFC SIM nothing changed on the system, just unplugged on SIM and plugged the other one.

Very odd behavior however that reflashing the 20150330 doesn't solve the issue, but reflashing the 20141116 solves it.

I can ensure it is not a "corrupted NFC-Enabled SIM" because in Nexus 4 AOSP it works like a charm, the SIM socket also isn't damaged otherwise no SIM will work regardless of ROM version.

The NFC-Enabled SIM also works fine with stock firmware. So.. I'm sorry to say it but there must be something buggy in your ROMs, I'd really like to use it and bring back my phone to life, with the stock firmware full of crap is almost unusable. I firstly choose this ROM because I know and trust the Cyanogenmod base source code.

What additional information can I submit to you guys to help the troubleshoot? I really really would like to use Lollipop.

When I say that a SIM doesn't work, what I can experience is that:

the signal icon is an empty triangle (No Service)

in the About Phone Menu, Phone Number and IMEI are missing

From the hidden menu (*#*#4636#*#*) under the "Phone Information" screen the IMEI is instead correctly shown, the Phone number is missing. Always in the hidden menu the Radio is constantly switching from ON\OFF states an d the GSM Service switches from "Radio OFF" to "Emergency calls only".

A notification saying that the SIM card is full and it is needed to deleted some SMS appear in the notification area.

Edit 2:

Damn god, now it works with NFC-Enabled SIM and 20150330 version

Flashed stock - NFC-Enabled SIM works

Flashed TWRP

Flashed 20150330 - NFC-Enabled SIM works - Made a TWRP backup

Restored TWRP backup made at point 4 "Second Scenario" - NFC-Enabled SIM WORKS

There must be something in the stock firmware that survive all the twrp, rom flashes and makes the NFC-Enabled SIM works.. or is there any kind of block when SIM is changed? If so how the hell does this block survive a clean install after wiping everything betwen rom changing?
