Hi,
I have followed the instructions from Cnet in order to root my phone.
When I download GalaxySim Unlock, it says Unable to read NV data.
Any advice on how I can unlock my phone?
Best Regards

Hi, I have a Samsung Galaxy s3 on three Ireland. I was wondering if flashing an open stock rom would unlock the phone. If yes then where can I download it. If no then what would be the easiest 'free' way to do so!?
Thank you in advance.
Flashing will not unlock your phone
Try this app
Would this app unlock my phone permanently? Would it stay unlocked if I unroot again?
Yep!
Unlock is permanent
Hi everyone. I have a GT-I9300 phone running on stock 4.1.2 that I can't get unlocked with the very acclaimed app GalaxSim Unlock (GSU). The app says my phone is unlocked, but it isn't, because I've never unlocked it and it prompts for a SIM unlock code after inserting a SIM card from a different carrier. I'll explain what I did with more detail:
First I flashed an Argentina unbranded ROM 4.1.2 (I9300UBEMH2). When I installed GSU there was a message saying "NV data inconsistency". I restored the efs folder backup I had but the message didn't change. So I tried flashing an Argentina branded 4.1.2 (I9300UBELL6) that was from the same carrier the phone was locked to (no particular reason, just a blind guess to fix it). Now GSU said "invalid IMEI" (0049...). The efs backup didn't fix it. Then I flashed the same unbranded again because at least it was recognizing the IMEI and, at my surprise, GSU said that the phone was already unlocked and there was no problem with IMEI, Serial No or NV data consistency. But now I can't use GSU to unlock my phone and I haven't tried any other app to unlock it. I've also tried an older version of GSU that was on a thread on this forum but I had the same problem.
Do you have any suggestions on how to fix this? Maybe try flashing another unbranded ROM? Downgrade to 4.0.4? Change something in efs folder? Another permanent unlock method without GSU?
I appreciate any help provided and I apologize if this problem has already been answered before (I've been looking for hours here with no luck). Just in case there is no solution I'll ask (and I'm not sure if this is against the rules, in which case this line can be deleted) if you know of a trusted and cheap website where I could buy a SIM unlock code (carrier charges way too much).
Thanks in advance.
GalaxySim Unlock does not work with release EFSv2. Modem version upper than MG4.

You must wait for a GalaxySim unlock update or obtain the sim unlock code by asking your carrier.

Thanks for the info. It doesn't solve my problem but at least I know why it doesn't work.
Hello everyone, I was able to unlock my bootloader and install AntonX Unofficial CM11. Now I got my sim unlock code from MetroPCS but when I try to access the unlock menu (2945#*769#) I got the error "Mobile network is not available." After going through very hard process to root and unlock my bootloader I don't want to go back to stock. Is there any way to enter the code on custom rom? Thank you in advance.

Hello,
I live in India and I purchased t-mobile s5 online and it already came unlocked and rooted. It was a bad esn set. I don't know how the previous owner unlocked it, but it was just 1 week old. So my guess is, he didn't asked T-Mobile for unlock code, but rather used some online services. Also, I'm unable to update my s5 via OTA and Kies method. While trying to update via OTA method, the following error message pops up:
"The operating system on your device has been modified in an unauthorized way. Try downloading software updates using Samsung Kies on your PC, or visit a customer service center."
And while trying to update it via Kies, it simply fails with a error message.
So my question is, while upgrading my s5 (to android 5.0) via Odin method, will I loose my sim unlock? Will it revert back to being region locked and I would have to purchase an unlock code?
Thank you.

It does not update via OTA because it's rooted. If he used the network unlock code then is should be safe to upgrade via Odin. If it's properly network unlocked it's very hard to lock it again. Rooting and flashing will not affect that.
Also, you can unroot (search the thread on rooting to see how to unroot) the phone and then it should successfully update via OTA.
Plus, if you have the contact info from the original owner you might be able to get him to send you the unlock codes. That way you would have them.

Oh! I see. Thanks for the info, but I'm not sure how he unlocked it.
I'm no longer in contact with him. I sent him couple of messages inquiring about the same about a month ago, but he hasn't replied me since.
I tried unrooting the phone, but it had no effects. I was getting the same error message.
BTW, I used "Kingo Android root" software to unroot it. But since it didn't worked, I rooted it again using the same software.
Flash a rom and forget about official ota

It's not the OTA that I'm worried about. I'm worried about loosing my sim unlock.
Problem Solved
PROBLEM SOLVED
I went ahead and flashed my phone anyway, and I'm happy to find out that I didn't lost my sim unlock.
Thank you for help guys.
was researching into cf-auto root and on the repository instructions it says if you flash the root with a phone that has a locked bootloader, then the phone will probably be bricked.
Is that the case with this phone? Do you have to unlock bootloader prior to rooting?
thanks
