you should ask this in the i9300 Q&A thread, they could help you out better, but as far as i know you will remain unlocked
once lock is removed you can flash what ever you like and it will still stay unlocked...even custom, or official samsung

Please help!

Hello Everyone,
Has anyone had any luck unlocking the bootloader for the Samsung Galaxy S3 Mini SM-G730A. I want to put another system on it but can't right now. I also want to use another carrier and can't do that either. Any help will be appreciated...

I did, but theres no other ROM made to put on it. d
Dont remember what i used but i do remember odin and framaroot but cant remember what else i used. I had it unlocked but found NO custom recovery for this fone and actually found 2 custom roms but neither one worked. Had phone rooted and unlocked then flased another program and lost root and locked the bootloader again. Crap, 3 days research down the drain. Challenging yes
but im just gonna keep using my Zenfone 2 with the CyanogenMod 13 Marshmello 6.0 as my main source of moding! stop wasting your time cuz it seems that noOne is working on custom recovery let alone custom ROMS for that old phone the Samsung Galaxy S3 mini SM-G730A. Too bad cuz its a solid phone that i have dragged around the world with me 2 xs. Samsung and AT&T both Suck.
Acually safestrap recovery was succesfully ported to the g730a.

if you update your i9305 via ota update or kies, you will get the knox bootloader (new bootloader since 4.3) and that crap is nothing but a pain in the ass!! read about KNOX here. I dont recommend updating to official 4.3 for now with ota or kies, instead of that use a custom stock rom 4.3 from any developer on the development thread of i9305 without knox. but first ask in the thread of the rom, if you will get knox by flashing it? knox itself is removed from those custom 4.3 roms but still i dont know for sure, i have the new bootloader with knox myself unfortunately
all this time since im on knox bootl. ive had no problems actually with the knox bootloader in all that custom roms/kernels/recoveries flashing etc. but some do have and maybe you will too...(i hope not of course, if you do update to official 4.3) but you are warned!
the problem is that I haven't getting any updates till now as my mobile is from oman nd im in india.....
Try this:
http://forum.xda-developers.com/galaxy-s3/development-i9305/rom-galaxy-s3-lte-jb-4-3-mod-t2607321
I'm also on 4.1 jb... and will try that as well...
Update to 4.3 isnt worth at all.
Well configured 4.1.2 with some useful application is much better.
I just recently updated my s3 to 4.3 and the knox app isn't installed its just a link to install it should I install it or not

I am still on 4.1, but as far as I know, the problem is not the Knox app, but the Bootloader for 4.3, which has Knox installed. Which means that you void your warranty if you install custom roms after updating to stock 4.3. Like MaHo said, read Here
The better advice would be to flash some custom K.K. 4.4.4 rom instead. It has A LOT more improvements than 4.3.

Update to 4.3 isnt worth at all.

i already did, everything seems to work, cwm is on, root is on, just didnt test to downgrade yet. And you cant install costum kernel for now
Thanks! Do I need to change modem after flashing or not? Or It is better to reflash 4.3 since I am rooted and Download 444 via OTA
i flashed it and works great...no need for wipe or modem...internet still work( 4G ).
My phone has been running Stock 4.3 since it went out. Fact is that I always used Screen Mirroring feature with no problems over that version, but yesterday I updated my Galaxy S3 i9305 to the latest firmware, 4.4.4. Now, don't know why my phone can't connect to my SmartTV as well as always it did.
Can anyone tell me any reason, please? My phone is running quite well, but not with that feature wich I use so often...
Thanks in advanced
