[I9100G] Network lock

Hello,
I received a Galaxy SII I9100G as a present last april in Morocco (I'm in France right now). They told me it was an "unlocked" phone (not bought from any operator).
The phone worked wonders with my SIM card (SFR, a french operator) from april until 2 days ago. It seems like it locked itself all of a sudden and asks me a code to unblock the network. That same SIM card worked well the same morning.
Anyone to explain what happened? I'm confused since I don't understand how it can lock itself without having to change the SIM card/flash/anything...
I called SFR and Samsung France to have the code, each one tells me to call the other.
I rooted my phone and used Galaxy S Unlock, it tells me that the phone is unlocked but after the reboot nothing happens. Tried also Galaxy S2 SIM Unlock, but it doesn't find the code.
I'm quite desperate right now since I'm waiting for some important calls this week and I tried everything, every tutorial but nothing seems to work.
I really don't know what to do to unblock it, I asked for help on many forums, spent yesterday looking for solutions but still nothing.
Please tell me there's a solution to this problem?
Thanks in advance for any help~
Samsung Galaxy SII I9100G
Version: 4.0.3 - I9100GXXLPN
PS: Actually, it does seem to work with a Meditel (moroccan operator) SIM card... Which I don't understand since it was supposed to be unlocked, hence why it worked with my SFT SIM card since april...
Hey i think some persons before you has coneckt it with a Samsung account and locked it now over the samsung dive webside. You can try to flash a new Firmeware to fix it
First, thanks for trying to help me.
I already flashed it with a new firmware (2.3.6 >> 4.0.3, always using official samsung), but still didn't work.
Unless should I go back to a previous firmware?
Any other idea please?

[Q] Samsung SCH-I939D

Hi guys,
I got in hands a Samsung SCH-I939D in China (where I live). Of course the Android version in it is a chinese Android with all kind of app sI don't want, no market, no google apps ect...
I looked on the forum for some info about this phone but the search engine didn't give me any relevant result.
Main question : Is it possible to find any custom Rom or at least non chinese rom possible to install on this phone?
Second question : Has anyone tried to hack this phone and is it possible to install google apps, root the phone or anything?
I have some intermediate knowledge about android (rooted, installed custom roms, unlocked... several android phones)
Thanks.

It works for my Audi A7, not able to manually connect every time though. Annoying. Phone going back anyway
Do you have the dual sim-version?
After some googling it seems like single sim-version supports rSAP while dual-sim versions doesn't..

Yes was single sim version. Now to try make my mate 10 connect via rSAP
That explains a lot, here in Norway the dual-sim version is the only one available..
The Mate 10 is not an option for me as the Huawei Mate 10 doesn't have QI charging.

Are you not able to flash the single sim firmware onto it?
I haven't tried that.. Is it safe to do so?
If you root, you may be able to install rSAP:

Seems rsap on exynos is supported. But not on the snapdragon. Damn. Cause I have both and and snapdragon is better right now. Snappier and less battery
Did someone try to root and install this
http://www.android-rsap.com/bluetoot...s-profile.html
on the DUOS version? I like this phone but I hate the missing RSAP funcionality...
(I have the Exynos version)
Same thing in France/Belgium/Holland/Luxembourg , the single sim version is not sold in those countries, therefore no RSAP profile in any of those countries... It's really a scandal!
It's time for everybody to contact your sales support in your countries to ask for a software update to activate RSAP, only pressure will make them create an update
anyone ???

RSAP on S9 Duos
I tried it now on several variants without success.
Stock Rom Rooted, Stock Rom PIE Rooted, Custom Rom on PIE (The Galaxy Project) Root or without root. The RSAP installer does not work. Even the expensive paid version from a different supplier does not work at all. Has anyone found a fix for it. Since i really need this feature to connect the phone to my car. Otherwise it is kind of useless to me.

In the same boat s7 edge worked a treat thought s9 plus would be the same but no :/
last week some people with S10/S10+ duos started to report after update to A10 that rSAP is available when only one SIM is inserted in phone, can someone with official FW with A10 for S9+ for Germany can confirm this?
recommended is remove car from paired devices and also remove phone from list of paired devices in car
My S9 should be single SIM ... It's from Vodafone Italy but rSAP seems not working on my VW Touareg RNS 850 Infotainment System.
How can I check which HW version is my S9 ?
Is there any trick to activate it ?

Rsap works perfect in Android 10 in the s9 Duos even with two Sims inserted. But only in a stock Rom or stock custom Rom. Trying lineageos 17.1 right now, but it does not Seem to work
