Issues with updateing to 4.3 and loosing Unlock - Galaxy S III Q&A, Help & Troubleshooting

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.

Atrix network locked"phone is subsidy locked"or"network unlock request unsuccessful"

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

if its hard locked, what are my chances to unlock for other network.and how....
Now I can able to usee at&t but not other network...(cant use at&t due to roaming cost)

[Q] SIM-Unlock Issues

TL, DR:
HTC HBoot 1.55, Bootloader Unlocked, Rumrunner S-OFFed, SIM LOCKED Unlock sites such as 247unlock can't find an unlock code. Any solutions?
Long Version:
I purchased my T-mobile HTC One 32gb for use on a Canadian Wind Carrier in August, paid for an unlock code via 247unlock, worked great, used it trouble free for 4 months; everything was stock. Until November 1, when the phone received the OTA 4.3 update; worked great for one week than it bricked itself when the battery dropped under 10%, would not boot up not matter what I tried...literally tried everything.
Ended up sending it back to HTC, they repaired it free of charge, sent it back, and now it's locked again. The problem is that I can't seem to find an unlocking service that can unlock it. I am 100% that it is the same device as the Serial No. is the same but the IMEI seems to have changed, as it is different from my records. Is that unheard of?
Out of desperation; I scoured the internet, a couple websites make mention of using S-OFF to sim unlock the phone; so I unlocked the bootloader via htcdevs, and S-OFFed the phone via Rumrunner (1.55 Hboot, which only worked after I flashed it to Viper, stock wouldn't S-Off). So, where do I go now? What can I possibly do to unlock this phone?

OK youre talking about two different things here. the s-off business is for the bootloader. Has nothing to do with the SIM. A SIM unlocked normally has to be done by the carrier (they give you a code) but there are 3rd party companies online who can supposedly do it, for a fee.

Yeah, I am aware that SIM unlocking and S-OFF are completely different things; I was referring to online articles that state S-OFF could facilitate SIM unlocking. I have read through the whole thread about SIM unlocking the HTC One, seems as if little progress has been made.
UPDATE: I eventually took the phone to a Brick and Mortar unlocking store, and they were able to unlock it in 30 minutes...I'm puzzled to how they did this. Special hardware?

Will flashing my t-mobile s5 reset my sim unlock?

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.

Carrier unlocking a GT-I9300 on 4.3

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...?

Question regarding SIM Unlock and ROM flashing

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.

Thanks!
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!
