Galaxy S4 Custom RoM - Rooted & On KitKat

[Anonymous]

Hi all,

I am going round in circles trying to work this out and i am hoping someone on here can help.

I have rooted my Galaxy S4, installed GooManager and TWRP and ready to install a custom RoM however i needed to unlock my phone in order to continue i think.

Anyway have been sent an email from O2 with a code to enter IF i put in another SiM Card. Is this the right option? They have called this "unlatching" is this the right term in order to allow a custom RoM.

Any help would be much appreciated, i don't want to brick the phone and have to use Odin to re-recover.

Thanks

@MI5 One for you I think

Yes, you need to complete the "unlatching" before flashing a CR.
Once you place a non O2 sim card in your phone and boot up, it will ask for the code that O2 have provided you. Once entered correctly the phone will boot up and the non O2 sim will be working if all was successful.
Note: Do not use one of O2's MVNO's such as giffgaff or Tesco as it will not work to complete the unlock - It must be an EE, Voda or Three sim card.

Or you can get one free from any of those providers just by popping into one of their stores or you can order online.
