Unlock Samsung galaxy s3 GT-I9305

Found 14th Sep 2014
Hi

I have got a contract phone from T-mobile/EE which is locked with their network. I asked T-mobile to unlock it but they are asking £35 for that. Even after contract ends, I will have to pay that for unlocking it.

Is there any other way to unlock this phone as £35 looks too much for it. Any free way or cheap way to do it?

Phone details: Samsung galaxy s3 GT - I9305 (it's not the regular s3, it's the 4g ready or LTE one).

Any suggestions or guidance will be helpful.

I have seen few on eBay charging between £10-20 but I really want something under £5.

Regards,

G33H1

I have done all possible DIYs. None worked. Mine is Android 4.3 and all of the googled DIYs work on 4.1.1 or below.

sorry didnt read the full question. but those are decent prices. few locals charge upto £20 dont think you will get better than that.

You can either pay or loose all your data by resetting the phone via odin and flashing a 4.1.1 jellybean. Then using the trick then upgrading

Not a problem. Thank you for looking. I did check in local stores, they do charge £20. I am still in hope to find in cheaper. Found one

ebay.co.uk/itm…AIT

but don't know if it's legit and will work. Have left message for seller asking what he is selling, a code or something else.

It doesn't require rooting u just put your phone in download mode and add the required files to odin then flash. Then once you've done that do the thing to unlock your phone then update to 4.4

You are suggesting, I can downgrade it to 4.1, unlock and upgrade to 4.4 then still phone is as it should be without causing any issue with the contract (i.e. if there is any problem in the phone and I have to ask them to repair, it will not breach contract term that I messed up with the phone myself?)?

Is it true and doable?

If yes, please tell me how I can do it oO

Yes it's true.


You have to download the correct 4.1 jellybean update for your phone and install it via the odin tool you can Google how to use odin to flash sg5

Then you do the thing that unlocks your phone and then you update to the lasteat firmware.

Just make sure that you reset download counter once you've finished

I searched and found that it will root my phone. I decided to go for code instead. But, thank you so much for guidance and help.

Flashing the official 4.1 through odin won't void anything.

I might try one out of contract to check this.

Any updates on this g33h1? I'm in the same position with 4.3 and would prefer a cheap unlock code instead of flashing 4.1

I used ebay for this. I bought the code from complete_comms_solutions.
