Problem with unlock and EFS Folder - Galaxy S III Mini Q&A, Help & Troubleshooting

Hi i bought an Simlocked S3 Mini with crashed LCD.
Then i repaired it and flashed new Stock rom for provider A1 from Austria over it. Then i saw the Pre Rooted Rom i flashed it and Rootet my phone.
Then i wanted to unlock it via the Service menu but no Network lock Menu was there. So i flashed Dmod rom and hoped it will be unlocked, because in my galaxy note i only flashed pre rootet rom did Triangle away and flashed a Custom rom and had no simlock. Same on the htc Desire from my girlfriend, after flashing Custom rom no simlock. But s3 mini flashing custom rom simlock stayed.
Now i looked for the nv_data.bin method did not work then i wanted to make it with the nv_core.bak but in my efs folder there is no file named like that?!
What can i do? i have no warranty on this phone. i mean real warranty ^^ because i bought it. i can use it only with a1 sim.
Thx for help or other instructions. greetz tom

Have you tried to flash other official firmware throught ODIN?

Yes i flashed Stock Roms with odin to geht the EFS folder rebuild but always same. i flashed the DBT Germany Rom the Open Austria rom then the Stock Provider rom nothing.. what can i do now?

its pay in some dedicate web for your network unlock code.

Ah like on Sammobile? i choose model and type in the imdi number and then get the unlock code? then i have to put in another Sim and when network lock pops up i give that code in therE? is that then a Permanent unlock or will i loose the unlock after flashing a new rom or making a Factory Reset?
Hope u can answer this Question.

The FIRST thing you have to do after anything is to backup your EFS folder...

I did. Yesterday i then shut down phone. it shuttet down in split second and then today i wanted to start it but nothing happened.
I cant start it and no recovery and no download mode. if i plug it in to a/c nothing. nice ****ing bricked phone.
first phone which is bricked for me....... man or is it only a security shutdown?

No. A custom ROM wouldn't lock or unlock the phone. It can be unlocked for any SIM and still be stock firmware, it can also be unlocked for any SIM and have a custom rom.
The two things are completely different.
Hope this helps.
You can do whatever you want to any rom, and that won't affect anything that makes it unlocked
thx for replying,
so meaning, currently the phone is unlocked, and i downgrade to RC29
so it wont be locked again ?
because need to downgrade to root-ed the firmware....
is this mean, downgrade my unlocked phone firmware to RC29
in the process, it will not reset my phone from unlock back to lock status ??
if it will not make my phone locked back again during the process
and i success downgrade to RC29 i can gain root access, then i can update to custom firmware
so another question, in the upgrading process (flasing to custom firmware or cupcake 1.5) will it set back from unlock to locked ??
sorry for my bad english
appreciate for replying, i need to know before i done anything
in the process,
Hi. I also have an unlocked phone. It was unlocked prior I downgraded it, and flashed new custom roms, and it is still unlocked. As the others said no need to worry, if i'm right the locking thing is in deeper level. Of course everything you do with your phone is your responsibility.

Can T-mobile still unlock the phone after I rooted it or would they know that I put a custom rom on it??

Yes, you can still unlock it through T-Mo. No one at T-Mo needs to have physical access to your phone, they can give you an unlock code over the phone.

One has nothing to do with the other. ROMs have nothing to do with the SIM cards and SIM cards have nothing to do with ROMs. T-Mobile isn't going to come to your house and spank you for having a custom ROM because they "know"

Why unlocking befor flashing?

I want to flash my samsung with the newest firmware from "samsung-firmwares",
but why i have to remove before my simlock (it´s a branded from A1).
And what happens if I flash without removing the simlock?
Thanks.
I also have the same question on my thread, no body seems to know if we can really flash simlocked units.
errors on boot i suppose ?
So Android phones actually combine simlock with different firmware locking (CID lock?) ??
The hell with that, then. In any other phone we can flash the firmware without the worry about simlock.
i rooted mine and it is sim-locked. never tried to flash tho.
just chiming in that we need some sort of confirmation/assurance that flashing is/ain't possible.

i got the same qeustion, mine is root as wel but can some1 confirm that we can flash the phone when its locked?
and is there a way to check if your phone is simlocked??
Mine is SIM lock (i think, never tested) because it was A1/Vodafone branded when i bought it..
After flash the brand was gone, but dunno with the simlock, as i have A1...
you can flash a locked phone without any problem. it will stay locked though after reflashing. if you flash a generic firmware you will get rid of the carrier personalisation.

Is it safe to flash simlocked Galaxy S?

Is it safe to flash simlocked i9000 with odin?
IMO theres no connections between flashing and simlock, but want to be sure.
Cheers.
I flashed my simlocked SGS using Odin and I had no problems. There are other few cases in the same situation and they had no problems.
Will a new ROM get rid of the simlock?
no, it wont, this would be to easy to dream of...

No problem to flash, I did it many times already, try also 2.1 and 2.2 android on it, lag fix, etc. Everything working normally...and, of course, the lock remain in place!

Mine is simlocked. Flashed sever times and all is perfectly !
just make sure to run Odin on a windows machine with English US settings
i screwed up a flash because it was running on a machine with Non English US, it got stuck on the 512.pit mode, but it wouldn't continue
My phone has simlock.
But i dont now of i can flash it to JM5?
Somebody now how i can unlock my phone ?
My precious is simlocked and I had no problems flashing other firmware. For example now I'm running a pre-rooted XXJP3 flashed through Odin. You cannot get rid of the simlock by flashing other firmware, you have to buy the unlock code. I'm waiting mine.

Hi where are you getting your unlock from
I tried with globalunlock but they were not serious, I had to raise a dispute/claim to Paypal to get my money back. Now I'm trying with someone from my country (i know his name and address in case of.... )
Hi!
My Galaxy S was locked too.
I tried unlocksamsung.co.uk and they sent me back an unlock code in one day. Everything is fine now.
I got my unlock code in 24 hours using a romanian guy services found on an ebay-like site in romania (okazii). Everything went smoothly and now my precious is sim unlocked
My phone is simlocked and ive flashed it several times already.
Will it be OK then to flash a sim locked tmobile 2.1 with a vodafone 2.2 with the kies registry fix

Signal problem

Hi , my friend asked me if I can unlock her X8 from T-mobile . After few theards on this x8 forum I thinked I can . I rooted the phone , installed cwm recovery , unlocked the bootloader and flashed nAa kernel, and I flashed a CM7 rom. The phone ask for pin code with an O2 SIM but there is no signal at all and a small icon like sim erro or something like that, When i go to settings and research for networks an try connect to o2 there is a message (cant connect to network). I read somewhere that relock the bootloader would help. Thanks .
AND I´am not such a noob, i had 3 android phones all were rooted , now I have an I9100(Galaxy s2) and i unlocked the phone.
Ehw, sorry wrong thread , can someone redirect it to Q and A
I don't think that if you unlock BT it will Sim Unlock phone. It only allow you to use Custom Kernel. Correct me if I'm wrong

Unlocking Bootloader or relocking it won't sim unlock ur phone.
Also flashing custom recovery or custom rom won't help.
you sure you using the right kernel? check the date under the battery first, then use this tutorial: http://forum.xda-developers.com/showthread.php?t=1254225
same error
Hey, my x8 has no 3g signal after official update, i think that maybe because he is imported. Anyway, i changed basebands in this new version( 2.1.1.a.0.6) and no 3g, update to 2.1.1.C.0.0 and all basebands and nothing 3g. I want the 2.0.2 firmware to install.
And i think that your problem dude, your version isn'r compatible with your signal, u will ahve to install another version

Flash stock rom without Sim Unlock

Ive just got my new P9 on O2 UK contract, which comes with O2 splash screen and Bloat.. As Ive just unboxed the phone... Can I flash the unbranded UK/EU stock rom without Sim Unlocking my P9, I know you can do this with Samsung and XPERIA handsets..
Thanks
OK, took some searching .. but found it.. Answer is Yes... you dont need Sim unlock or Bootloader unlock to use a stock Rom.. but you do need to force flash. Its all in here:
YOU do this at your own Risk..
