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.
One good explanation here : http://forum.xda-developers.com/showthread.php?t=2393289
You must wait for a GalaxySim unlock update or obtain the sim unlock code by asking your carrier.

Atrix network locked"phone is subsidy locked"or"network unlock request unsuccessful"
Hi, I have atrix, borught in last year and got reaplced with at&t in feb2012..It was under the at&t policy so got replaced with refub atrix in feb 2012.
I was travelling abroad in may2012 (india) so I asked the unlock code. they provided me the code.. But unforchunately I enter wrong code 10 to 20 times (i know I am stupid here)... So contacted to at&t cust care.. they said you have correct code... now it has not working with at&t sim also...
so could you guys please tell me the solution to unlock sim so I can use in India???
My atrix is 4.5.91 with baseband 1.77.36
I rooted, unlock bootloader, and factory reset few times already...
Even now it was asking "sim network" unlock code but it wasnt successfull...it give me message "phone is subsidy locked"or"network unlock request unsuccessful"
Is it possible to use custom rom or new update 4.5.141 or any international baseband to use in India or atlead accept unlock code so I can use it...
THanks
PS I am not expert in phone roots or customs etc..but I am above average (with instr I can format or updates roms)
all i can say is that i have read in the forum that if u change ur radio then even valid unlock code wont work. so my suggestion it to get back to stock every thing (as much as possible) and try the unlock code again.
try using fruitcake to get back to stock and best of luck with that

I have changed my radio many times and unlocked without any issues a few weeks back after getting the code from AT&T. I fail to see how a change in radio will prevent SIM/network unlock when AT&T themselves update the radio through their OTA upgrades. Even after unlock you can still continue to OTA with AT&T, have your radio updated through the OTA, (with a stock phone and locked bootloader of course), and not have problems. Without researching what you say further, I can only assume that changing the radio from AT&T to an international variant might cause problems. Do you have a link to where you read this?
Also, when you have used all attempts to network unlock, (10 tries I believe), you are hard locked.
I attempted to move on stock 4.5.91 and tried to unlock but still not able to
"phone is subsidy locked contact your network provider"
Is there way out from here

Now I can able to usee at&t but not other network...(cant use at&t due to roaming cost)

is anyone else having the issues that when they update there GT-I9300 to the newest update that they are loosing there unlock.
i have a phone that a client just dropped off and i guess he ran a update via Kias and after the update the phone will no longer except his sim card and the device is saying it is locked again
Firmware after EMG4 introduces v2 efs folder, which breaks previous unlock patches. No way around (that's why they did it) so you'll need an unlock code.

even if it was bought as a factory unlocked phone. guess i should of included that in the OP
'Bought as' and genuinely factory unlocked are two different things. If the phone is an unbranded handset bought as unlocked then you have a warranty claim, my unlocked phone went to 4..3 without issue.
You originally said "losing their unlock" which sounded like the more common case of handsets sold as unlocked, but only by patches which no longer work.

well the phone was bought out of the US as a factory unlocked phone. and the client ran some update via Kias. and after it booted up it would no longer take his net10 sim card. so i flashed it back to the UK unbranded 4.2.1 OTA and i am still getting the same msg asking for a unlock code.
when i run galaxysim is states that the phone is completely unlocked. and if i open the service mode menu to try and unlock that way the last menu is empty.
i have herd of the S3 getting this new region lock this but im not sure if that is what it is or if something is just really screwy. i have tried many diffrent version of the OTA. 4.0.4, 4.1, 4.2.1, 4.3.
if i go back to a update before july 2013 i run into the issue with the EFS folder so now i have the july 2013 UK BTU 4.2.1 OTA on the device. and im just not sure what to do anymore minus tell the client that he might have to buy another unlock code.

Doesn't the phone have to be complete stock when you do the unlock code? Once you unlock the SIM and put your new SIM in then you unlock the bootloader and do your root. Not sure but it could be the reason.

Hmm. Im stock just rooted and bootloader unlocked. I dnt think that would affect the unlocking procedure. But then again, im unsuccessful so far. I will try to revert to complete stock. And try the code again. Also should i revert back to jellybean? Or kitkat fine?

I would think as long as it is stock the version would not matter.

ok. i downloaded an RUU file. legit and with matching MD5. when i run it it asks to update to 4.20.502.1 ....from my 4.18.502.7. should i stay away from upodating it to 4.20.502.1 ....or its ok?
update: i have reverted back to stock 4.4.2
i removed s-off and locked the bootloader. and RUUed the 4.4.2 update.
but i am still getting incorrect code.
so frustrating.
I'm in the same boat. All stock kit Kat. Unlocked boot and rooted. If I figure it out will post here & would do like wise.

Hey XDA,
i want to carrier unlock a locked GT-I9300 i just bought.
If all else fails, i just wanted to know if flashing a whole stock firmware incl. Modem/Bootloader/CSC will get rid of the lock, also?
I read lots and lots about unlocking a 9300 with Android 4.3 here, unfortunately, i am less sure now than before...
got a prepaid SIM today, will see what happens later.
GalaxSim Unlock doesn't work; i doubt the code to enter will.
Is there sth one could do via ADB to get rid of a carrier lock...?
Dear community,
I unlocked my SGS3 for all carriers through a nearby shop one year ago. He told me I have two options: Either a much more expensive IMEI Unlock, or a much cheaper Software-Based SIM Unlock. There seemed to be no downsides to the Software Method, even though the guy there told me that I should not flash any new roms since that would destroy the Software Unlock (but resetting the Phone would be no problem).
As of lately, I have been looking into several new ROMs which look very nice, and I would like to flash them...but I am afraid that it would brick the SIM Unlock. Now here is my question: Is there any way to find out what that guy actually did to my Phone? And secondly: Since the S3 is already VERY old, is there a possibolity to unlock its IMEI? Or any other SIM Unlock Method which I could apply myself?
Btw: My carrier is "3" (Hutchison), Austria.
Any help is appreciated! Thank you!
The s3 can be unlocked via code as long as the unlocker can access the unlocking code database.
Usually, unlocking the s3 via code or software is permanent. I have unlocked s3 i747m phones, using a secret dialler menu and code, none of which have relocked after flashing stock or custom roms.
Thanks for your help!
So, should I just go for it and try it out? Maybe it will stay as it is but I am not sure...
Has the phone EVER seen a 4.3 rom?. If NOT, you CAN do the nvram unlock method. Out of 1-10 on difficulty its about a 6. You MUST BE VERY CAREFULL!.
The fact it was done software tells me that it would have been a galaxsim unlock which "should" be permanent.

Yes, as far as I know, it had a 4.3 Stock Rom at some point, but I installed the official 4.4.4 Stock Rom later on. Thats why I want to switch to another ROM, hoping that the performance increases.
There was no official 4.4.4 for the i9300. It stopped at 4.3 but seeing as you know it had 4.3 the only way to unlock the simlock is to pay for it.
I doubt you'll brick the device as there is always odin. The i9300 is quite resilient and in most software cockups flashing back to stock with odin will fix it to the point of a "working" device.
If it was me I'd risk it and odin if it goes wrong so make sure you have a usable stock rom before you start.
IF it does relock your phone you can pay about £10 - £20 (gbp) to have it permanently unlocked for any network and it should be unlocked while-u-wait, taking approximately 5 minutes.

One guy already tried to unlock it using the IMEI-Unlock method, but he did not manage to open the menu where he can enter the IMEI-Unlock code - even after inserting a SIM-Card from another carriert, there came no option where you can enter the Unlock Code. IF the device is locked again after I flash a new ROM, I hope that it can be at least unlocked once and for all by the IMEI-Unlock method...
Did you try flashing the stock 4.3 ROM from here: http://www.sammobile.com/firmwares/database/GT-I9300/ in order to enter the unlock code?

Thank you for your kind help, but there was no need for that. I actually flashed a new ROM and the SIM Unlock is still there! Very very nice!
A huge thanks to you all for offering me your help!
