I'm about to move to Australia and wanted to unlock my Samsung S3 LTE, which is currently locked to EE. I've looked at doing it via the network, who charge about £20 and also on Ebay, who don't seem to support my phone. Is there a way of unlocking it?
The phone is running Android 4.3 and hasn't been rooted or customised in any way.

that guide is useless... you can't downgrade to 4.1.1 once you got 4.3

Stop saying crap. You can downgrade if you didn't install a stock 4.3.

Hi,Pianoman91,you can unlock your device method downgrade- flashing firmware 4.1.1 from this forum:http://www.htcmania.com/showthread.php?t=738977
You need previously root your device,install a custom recovery and then flash firmware 4.1.1. Then use the hidden menu.This must to work!Before you must to make all backups.
Once done,you can flash again 4.3 frmware.You have to be aware that this proces will change Knox status from 0X0 to 0X1. This method is tested and works.Make on your own risk.
Thanks a develloper fzeta !
Best regards!

Need to explain that is not downgrade to Bootloader 4.3/KNOX/-this is impossible for the moment.This way we make downgrade to firmware 4.3-4.1.1.:good:

As mentioned, using this does trigger the Knox counter- but if that doesn't bother you then it's worth doing this method to unlock your phone. After I'd used Odin to go back to 4.1 and unlocked the networks I just reconnected the phone to Kies and it then updated the firmware back to 4.3. Tried a Vodafone Sim card in my phone today to make sure it was unlocked and it worked perfectly.

We are talking about two different methods,Pianoman91.I think if you try flash oficial firmware from 4.3/official/ to 4.1.1 trough Odin you will not be able to do it.Downgrade to bootloader 4.3 it is impossible in this time. But if we apply the method I mentioned should work .You should flashing trough Custom recovery a firmware modified.

I read that the Cricket Galaxy S5 (G900AZ) is a rebranded AT&T S5 (G900A). Has anyone tried ODIN flashing the stock AT&T rom on the Cricket model?
For instance, i have read people flashing the Tmobile S5 stock rom on the MetroPCS version and it works fine even though the model numbers are slightly different. It changes the phone into the Tmobile version.

Did you ever get an answer to this?
NO, but....
The Cricket S5 is indeed a rebranded AT&T model. I have both of those models including a LA G900M (TTT.) Major difference is nowhere near as much bloatware, and most importantly an unlocked bootloader. The only advantage would be upgrading to MM if you want stock, since the January update still has it on LP. You're better off trying a LA stock ROM though (I say this because they use the same custom recovery) But cutom ROM's can take you there as far as 7.1 Nougat right now.
I just recently rooted my Cricket model with CF Auto-root (klteaio), flashed the latest TWRP (klte) recovery and installed Xposed Framework (by dkcldark... wanam custom won't work.) Had a little of lag first couple of days, but I guess that's to be expected. Hope this helps in some way.

This gives me an idea.... What if we use flashfire to flash G900AZ firmware on the G900A (including the UNLOCKED BOOTLOADER)

You could always try it. I don't know exactly how well it will work.
You would have to be rooted FIRST on the G900A in order for FlashFire to work. If i remember correctly anything already on LP can't be rooted or downgraded back to KK.

Y'know what would be really nice???: Seeing that android updates are only good for 2yrs on a particular model after its initial released, and the given the fact that most carries plans are only 2yrs; wouldn't it be nice if (for sake of argument in THIS thread) AT&T would release a firmware for their phones, that would unlock the bootloader and possibly SIM unlock the phone as well. I mean after 2yrs the device is paid for and quite frankly no longer belongs to them. I hate the idea of being forced to either get a new device once my plan has expired or use MY phone with the carrier its branded under. Of course it probably has everything to with them making their money from those of us who can't do without having a new device every year.
So I can pull a copy of the G900AZ engineering firmware I found, but I doubt we'll be able to flash it. What is was thinking is that we use beaups CID changer to make our device into one similar to the cricket wireless one. Since it is essentially a dev edition of our phone.
You cant just flash a unlocked bootloader to a locked bootloader phone. A specific explout must be developed to defeat the bootloader. Simply shashing over it will never work.
The G900AZ is just a rebranded version of the G900A though. I don't think there are any glaring differences like there would be from G900T to G900A. If the aboot does flash then it would be a simple unlock.
@NavSad @AptLogic
If you wanna try this, here's a link to their firmwares:
https://www.sammobile.com/firmwares/database/SM-G900AZ/
You'd most likely need to extract the correct files and be on the correct versions before flashing these.
Apparently, something similar happened with the T-Mobile Galaxy S6, where the MetroPCS firmware was flashed on the T-mobile firmware.

So I tried using FlashFire to flash the G900AZ firmware and I HARD BRICKED MY PHONE.
If anyone wants to give me advice on how to unbrick it PLEASE DO because I have to put all my development on hold indefinitely until I can unbrick it or buy a new one (which isn't likely because I don't have the cash for that right now).

I would try this method:
Grab a sdcard
Grab a debrick image here:https://www.androidfilehost.com/?fid=457095661767140194
Then put the sdcard in your computer and use Win32 DiskImager to write to the sdcard. After that, put the sdcard in your phone and boot into Download Mode.
If your phone isn't fixable using this method you'd have to try JTAG.

Hi guys I had thes8 plus and first thing I did was root and flash custom Rom when it come to selling it to get the note 8 I hated how many apps where still broken from tripping knox
My question is I don't want to trip knox again on my note 8 but how easy is it to trip knox?
Can any apps from app store trip it by mistake or using adb to say go to full immersive mode?
Or a couple off modded apps like YouTube modded?
Thanks

The only thing that will trip knox is flashing a custom recovery - which is required to root.
Don't root and you will be fine.
no apps can trip knox
adb wont either

You can use Odin without tripping Knox, you can flash other Samsung firmware and it won't be tripped just don't Odin a custom recovery.

Kind of you could still flash stock firmware fine if you needed to recover from a soft brick of some sort.

It has the recovery needed to root (trip Knox) and has instructions on how to flash it. Does not get any more straight forward than this.

Check out the samfail thread. They can help if the answers aren't already posted there.
No help there I think I'm screwed unless they find away to unlock snapdragon bootloader or some way to downgrade from rev3 to 1 or a remove/bypass solution.

It can't be very legit if you bought something that shouldn't actually have been sold in the first place! Either way, these are not retail models so I honestly have no idea where to get the firmware for them.

No, locked bootloader on that model. There used to be SamFail for root, but I believe it's been patched by Samsung through firmware updates.
Ok, thanks, I already have it rooted through samfail from when I first got it. (I never update unless it is buying a new phone) I was just hoping i could get twrp after so long. Thanks
