Google edition bootloader

Hey I'm sorry if this is a really noobish question. When the google edition gs4 is released would we be able to take an unlocked bootloader from it and flash it over the att stock bootloader, thus unlocking the phone?

No, not possible.

Galaxy s4 to Google Edition S4

Hello
is there anyway you can flash the stock image and recovery from a GE s4 onto to standard s4? so will pick up updaes etc..?
see this done on HTC One... wondered if it can be done? or does it have to be via a Rom?
thanks
would like to know the same
Not yet. Bootloader needs to be unlocked to transform S4 in S4G
Not possible at the moment, you can have the google edition roms though but again no OTA's and same partition sizes

Really a little confused about this answers...
We all can flash a custom recover on the S4's, previously rooted, so this by reading some explanations on XDA:

Means that the bootloader is already unlocked. Or not?
F.
Bootloader does nothing. Janjan 4.2.2 ge rom ftw

I'm sure you can carrier unlock your S4 and allow you to use another Sim card. Try searching for it

I think you can carrier unlock for 3G data only. But I think Sprint has to give you the code, and you have to be off contract or paid up on your phone.
If you look around you will see the domestic unlock only rolls when you are on mf9 bootloader and can go back to mdc If you are on 4.4.2 the best you can do is foreign unlock after 90 days on Sprint and then they will unlock it.

[Q] Is it still possible to unlock AT&T Galaxy S4 4.4.2 with IMEI

Im just wondering.
You should be able to used the IMEI to get your unlock code.

bootloader unlock questions

I am curious as to what kind of methods can be used to unlock a bootloader. I must mention I am VERY grateful with hashcode's hard work in getting us safestrap. However I am still curious about the bootloader. Can it be unlocked by exploits or only by cracking the lock code?
