I recently unlocked an S3 for a friend, I did the whole downgrade to 4.1.1 method then the *#197338640# now my question is this, if she upgrades the phone when she's on the new network back to 4.1.2 will it ruin the phone being unlocked? Thanks, first time I've ever done this.

gt i9300 international SIII has no locked bootloader (only one I know is verizon one). so either you are in the wrong SIII forum or you have done something unnecessary...
Your right, sorry. Like I said I did this for a friend I don't own an S3 so I didn't know where to post. Thanks

No, SIM unlock is permanent and can not be reverted by flashing OTA.

I recently bought my galaxy note i717m from Bell in Canada and unlocked it with network unlock code purchased on internet. Then, I got someone from kijiji to root my phone and upgraded from ics to jb and made the phone to work with wind/mobilicity. I am now using a wind sim card on my phone but i found out that the jb system is very buggy and crashed too often, Anyone knows how to downgrade jb to ics or recommend a more stable jb rom? Does downgrading to ics or changing to a new rom will make my phone not supporting wind/mobilicity anymore? I dont know anything about android btw, anyone kind enough to write me a simple guide? Thanks a lot!

how to check?
Okay restart the phone by pressing power+ volume up and down at the same time until you see the first Samsung logo tht will take you to recovery that's is how you will see. Seems like you are new to this. Most of all the jb roms out there are good but buggy and also battery drainers I speak of past experience long story short if you want stability keep stock ics until jb is officially released...

Im now using Wind mobile, it is using the same frequency as tmobile. I just want to downgrade to ICS without touching on other things so that my phone can still support the AWS 1700 frequency.

Nice guide, thanks so much! However, my phone was bought from BELL store in Canada,does it the same stock rom as AT&T? When it was bought, it was locked to bell, unrooted and only support 1900/PCS frequency, does not support 1700/AWS frequency till I got someone from kijiji to help me turn on the AWS radio frequency support in the phone by flashing rom, rooting and stuff. If I follow your guide, would my phone get locked and lost support to AWS frequency?

This one you have to Odin it but ur ain't hard just make sure you back up all of your internal sdcard stuff since this Odin will wipe the crap out of the system lol happened to me luckily the external SD didn't got wiped. By the way
By doing this you will loose root and also clockworkmod you have to re root the phone

That means the phone would not support wind sim card and its AWS frequency just like when it was bought at the bell store, locked?

okay, thanks for your help, I will ask Wind about that.
A friend of a friend was giving us a lift today, and she asked if we could turn on navigation on her phone since she was in the middle of driving. Her phone is a Galaxy S II, definitely i9100 and not the other variants (4.3" not 4.5", physical home button). She was running it on Telus but she bought it second-hand a few weeks ago so I assume it was a Bell or Virgin model.
Anyway I could see from afar that it was most definitely still running Gingerbread, and I wondered why it hadn't gotten the ICS update. I asked if I could see the phone and I went to the About screen - it's running 2.3.6, and the build number says Super ROM. Then I looked in her app drawer and saw Superuser. She is not the type who knows how to root a phone or would even want to, so the likely explanation is that the seller had installed a custom ROM and neglected to revert it before sale.
I've never owned an i9100... If she were to ask for help returning it to stock, would the simplest way just be to flash the Bell ICS ROM using Odin? Are there any precautions I'd need to take in case something the last owner had installed would be incompatible with the flash?

To be clear, she is a non power user. The ideal ROM for her is whatever would've been on there by now if it had never been hacked. So I believe that'd be ICS.

Just flash the ics of bell version since shes not a power user i did the same for wife shes has no intentions of using any custom roms for her just basic use
and i assume you know where too get that and yes flash in odin the stock version either from here you can get it or samfilmware ics version for 19100m
cheers
Thanks!
Actually I should add... The SuperROM she had on there said the device was i9100G. Is it possible that's just because it's what it says in the ROM, and it's still really an i9100m? Cause now I see they have different processors...

Hey. You better first make sure that the Galaxy S unlock tool isn't there, otherwise that's how the seller sim-unlocked the phone. Putting it on ics may lock it back up but you can unlock it again. If you move it to jellybean though, the unlock tool doesn't work yet. Ics is good enough for her.

Hey I'm also looking to update my phone and I'm sort of in the same situation as this girl. I bought my phone second hand and found out later that it was rooted and has CyanogenMod 7.1 on it. My model is the I9100 and my provider is Telus. I was looking to update it to CM10, but one of my concerns is that it might get locked again and I won't be able to use my phone on Telus. Should I just settle for CM9? Will it for sure get locked again? I'm a noob.

Presumably if it's genuinely an i9100G and not m (I'm not sure, as I only saw the phone once), it wasn't from a Canadian carrier. In which case who knows how it was unlocked.

I'm new to the site so please excuse my potential ignorance if this has been previously answered or if I missed anything.
So, I have a Samsung Galaxy S3 i9305. It was originally on T-Mobile UK but was completely unbranded so on startup doesn't show t-mobile, no network bloatware etc... and I have since had it unlocked (via unlock code, not root)
Waiting for the premium suite update has prompted me to wonder... as I am unlocked am I still governed by t-mobiles wait times to release the update (I actually use a voda SIM in it)? Or as its unlocked/unbranded should I effectively be at the front of the queue as it wereand receive it with other unlocked handsets? Or will I not get it at all as I'm not using a t-mobile SIM?
I'm becoming very impatient waiting for the update as got rid of my note ii in anticipation for the s3 receiving the update. Which after giving more thought to I'm not even sure if I will receive as I have the i9305 rather than the i9300 and they didn't really say specifically who the update was for?
I am on the cusp of rooting just so that I can add the premium suite on the Rom but have limited experience in rooting (only done it a couple of times) worried that I'll miss something and wont be able to return it to stock once the upgrade becomes available via kies as there are so many different guides/roms/software
Appreciate your thoughts

Don't quote me but I don't think it matters what SIM you have in, you should still see the update when it rolls out to that model number.. so long as your not rooted.

Update has nothing to do with locked or unlocked .
You get the TMobile update for your phone .
Or join XDA and flash a stock rom .

Thanks for the info so far. Can someone tell me if I need to do something specific to ensure I can restore to its original non rooted state in the future as I can't wait for the update anymore.
The update is out in the UK but I haven't received it yet

This is probably a stupid question but hey, can't hurt to get some input.
I have recently found myself in possession of an AT&T Galaxy Mega. I have T-Mobile as my carrier so have no intention of using the built in 4G from AT&T. Can I flash a T Mobile rom and baseband to it? I assume this will brick it and I am better off just leaving it be and using it as a plain wifi-only tablet but want to verify with the experts.
I am no novice to flashing/roming and the occasional brick recovery
Sorry, but you can't flash ANY rom to the ATT Mega. No one has been able to unlock the bootloader.
But, I'm sure, if you search, you will find folks are using a t-mobile sim in the ATT version.

Yeah, was hoping a stock rom from another carrier wouldn't need an unlocked loader. Ah well,, am rooted and just waiting for the official 4.4 then.
Thanks for the input!
So I did a little searching before posting so don't ream me please ??
1) Does the dev edition s4 also have a locked bootloader? That would be f'in whack.. If it us unlocked and my second q doesn't pan I may try and swoop one up. ..
2) I have a friend with a tmobile s4 that he cracked the digitizer and just reported it lost... If I took his board could I unlock it to big red? If so what would be the consequences?

The Dev Edition S4 normally does not have a locked bootloader. I say normally because some users took an Over The Air update which did lock the bootloader. So it depends on whether the bootloader is a stock MDK bootloader or if the user took a subsequent OTA update which in turn locked / changed the bootloader. Also, there is no factor image for the Dev Edition, so if it is locked it is going to stay locked for the foreseeable future. As for your second question, I'm not sure that will work. I think the firmware differences between TMO and Verizon plus the difference between GSM and CDMA will not be easy to overcome. But I don't know that for sure.
I'm not trying to be a know it all trust me lol but the dev s4 never got otas I don't believe. The users who locked then up did so by using Odin and retail firmware.
Just throwing that out there.

I don't take that as you being a know it all, you're probably right. I just know some Dev owners did something to lock their bootloaders I just assumed (wrongfully) that it was an OTA of some sorts. Sorry for the misinformation.

I know one user who received his DevEd about the same time as me. He received an OTA that locked his bootloader. I have never received an OTA, and I'm still running stock (more or less) DevEd.
It's funny how I bought the DevEd, because I wanted a guarantee that I could ROM the device. But I fell in love with the stock OS, and don't care if I ever have KitKat.

No kidding? I didn't know any of them got OTAs. At least you have the option to flash whatever you want if you did get bored with stock.
