[Q] Network Unlocking a UK Samsung S3 LTE?

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.

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!

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.

OMG! It seems we're gonna have many problems with this firmware version. Yesterday, after flashing the new 4.4.4 via Odin, I wanted to reinstall it for twice, and PC Odin brings me FAILED in step SetupConnection. Then, I tried to do a Downgrade to 4.3, getting the same error. I don't know what's happening but I don't wanna be stuck in this firmware forever!
Please, can anyone lend a hand?

most probably we won't be able to downgrade as it was 4.3->4.1, so we can't 4.4->4.3 due to some bootloader changes
I think you'd have to wait until 4.4.4 for non-N model is released as odin package

of course I don't know how risky it could be with new bootloader, but keeping in mind that people downgraded from 4.3 to 4.1 using mobile odin (no bootloader change) it could be worth trying

wanam xposed can fake the system status, but I don't know if it'd work in this particular case
anyway, full odin package for 4.4 non-N appeared, so no need to tamper at 4.3 DBT just to be able to update anymore http://live.samsung-updates.com/details/34084/Galaxy_S_3_LTE/GT-I9305/DBT/I9305XXUFNI3.html

[Q] SIM Unlock i9305 on CM11

Hi all,
Been reading all about SIM unlocking my i9305 - seems it's a bit of a minefield. I've got newer Knox bootloader, would appreciate best method / things to avoid!
I think I need to downgrade to official JB - was thinking this: http://forum.xda-developers.com/gal...305/rom-13-5-2014-official-stock-rom-t2573524
Then use the code I already have from eBay to unlock, as I understand I need a stock dialler.
Should then be able to flash CM11 again.
Couple of questions:
Would I lose custom recovery / root in this process and have to do that again?
Am I ok to downgrade provided I do full wipes?
All help gratefully received!
Cheers

Oh and one more question - if I go to official 4.3 and the unlock code works - can I just restore my nandroid CM11 backup or do I have to reflash from scratch?
Thanks

Best ask a moderator to move your post to the correct forum, anything from here can brick your phone.

Ah yes, please move to i9305 forum

Ok I bit the bullet and flashed stock (rooted) 4.3, all gone well and SIM unlock code worked.
Now can I nandroid restore my CM11 setup or will that revert the SIM unlock?
Thanks

[Q] Anyone downgraded from 5.0.2. to 4.4.4

Hello, I have upgraded to 5.0.2. via OTA a few days ago. My phone was RetEU .23, and the update notification that 5.0.2. became so annoying, so I decided to give it a shot. Lollipop is a disappointment for me, battery drain issues, lagging all over the menus, slow dialer, the phone was running better with KK installed, so I want to return back to 4.4.4.
Unfortunately there is no clear opinion whether this could be done, some say that when you have 5.0.2. bootloader installed with the OTA, you cannot go back, others say that it is no problem to do so. Really confusing.
Anyone tried to go back to 4.4.4. after getting the OTA? Could you please share how did you do so? Unlocking the bootloader and flashing one of the 4.4.4 stock ROMs from the General Section?

Hello,
i actually switched from 5.0.2 back to KK 4.4.4 from Pizza_dox
when your bootloader is unlocked and you have TWRP installed
follow these instructions
1, go do a factory reset
2, go to advanced wipe and select :dalvik cache/system/data/internal storage/cache
when you did that there is no system on your phone so when you restart you will be going into an endless bootloop.
3, go press install and select the Microkat.zip file from Pizza_Dox
when that is done you have agian kitkat on your device
i think there some other methods but this is how i did it succesfully.
Also dont forget to make a backup because you will lose everything.

Thanks for your comment. I actually plan to go back to the stock 4.4.4. I have a basic idea of bootloader and things but not deep into this and have never done it before. From what I have read , I will have to:
1. First I need to unlock the bootloader, as per the instructions in the Moto website.
2. Then I will need to do a factory reset. (settings-secuirity-factory reset or some other way of doing this?)
3. Download 4.4.4 firmware + script.
4. Start up with Power+VolDown buttons and have bootloader menu on screen
5. Run the downloaded script from its .bat file.
6. Wait for some time for the flashing to end, then have stock 4.4.4
Please correct me if something is wrong or missed.

What i did...
Download the correct kk stock rom
Setup my drivers and mfastboot correctly (simple fast boot works too)
Unlocked bootloader. (Voids warranty coz gives bootloader status 3)
Reboot in bootloader now...
Flash all files of kitkat except gpt.bin and motoboot.bin (they never flash for me lol )
Flash all other files (i typed filenames manually)
Fastboot reboot
Ps - no matter what i do..i have not been able to lock my bootloader once i downgraded from 5.0.2 to 4.4.4
Locking bootloader works well on 5.0.2

well guess im gonna try - but no need to do, as makes no difference except to downgrading.... So best off unlocked
simply use the 4.4.4 link in my signature and pick firmware 2 or B called DSDSALL to go back to 4.4.4 .23 ret(xx)

So, it has been confirmed by several forums that when you have officially received the 5.0.2 OTA download update, you cannot go back to KK.
It has something to do with the new L bootloader. I guess that there is no way of doing this, up to now at least. Don't know if someone has tried and succeeded.
When you have flashed the 5.0.2. OTA however, you can have KK installed back, as most of the users on xda.

No there is no hardbrick . If you are not on the right bootloader and modem the rom may not boot , so you just flash the right ones.
If you want to came back to LP flash lollipop last booloader and modem and you are ready to go.
Basically , bootloader allows you to boot the rom , modem is everything related to signal , wifi...etc if you are in the wrong one you will not have signal or some things working

Yes, you can. First backup your android 6.0.1 from your recovery, in case something go wrong, you can go back.

Won't flashing/ downgrading the bootloader brick the phone ? How do you flash the LP bootloader and modem?Please can you give a step by step guide and where the correct files can be found? Thanks
