I'm getting this phone soon, never had a Samsung before. When rooting this, is there a bootloader to unlock? And does Odin unlock it during the root process?
Thanks
If you want an unlocked bootloader, you have to purchase the Developer Edition.
The retail edition has a locked bootloader. You need to use safestrap if you want to flash roms, you will not be able to flash custom kernels. Odin is used to restore your phone, not unlock it.

I've rooted my S4, and I'm running 5.0.1 Stock rooted firmware.
I'd like to re-lock the bootloader so that no one can hack my phone by flashing a zip with a lock screen bypass, if I lose it.
Is there anything that can re-lock the bootloader, while maintaining root?
Thanks.
i have galaxy s4 i9505 and i want to know if i need to unlock the bootloader in order to instal custom rom(cyanogen).the phone is in stock condition(not rooted no roms or anything)ive checked the first 10 pages of google results and some guides say i if i dont unlock the bootloader i will brick the phone and some say i dont need to unlock it.i searched this forum aswell but i just end up with 100 tabs open and still cant find my answer.
The only thing you need to do is this. Install TWRP using Odin, then flash your ROM using TWRP. The only mention of locked bootloaders comes if you own an AT&T or Verizon Galaxy S4. Those two models have a locked bootloader that cannot be unlocked, and attempts to change the bootloader on those devices have led to soft bricks which can be resolved by flashing the correct bootloader in the BL slot in Odin.
Hi,
I am running on rooted stocked OC4. This was done following the instruction which uses Flashfire to flash ROM and then ODIN to flash bootloader.
I am now looking to flash custom ROM (T-Mobile ROM specifically). From what I can read, the suggestion is to use safestrap which get around the locked boot loader in order to flash ROM.
However, there has been no update for saftstrap on 5.0.
Flashfire was able to flash stock ROM. Does it mean it has ways to get around locked bootloader?
Thanks
The phone's bootloader is probably locked. It has never been unlocked, and I believe model SM-G900M was sold with the bootloader locked. (I tried to check if the bootloader is indeed locked, but fastboot did not detect the phone.)
I understand that in this scenario there is currently no way to root an S5, right?
It appears that the only way to go is to perform an Android downgrade. I would have to use Odin to flash a stock 4.4 ROM (is this correct?), then I would be able to root the phone with towelroot, unlock the bootloader and install flashfire on my device. Does this sound like a doable approach?
Suggestions/advice very much appreciated.
Thanks!
I have sg4 activate unlocked att software that it's unlocked can I install custom recovery or do have to do the whole firmware downgrade thing I have no pc so I don't wanna brick it it's rooted but with king root I bricked a sg4 damb near killed the recovery by not knowing better but it was locked at gave me unlock code I think that's my boot loader but I'm not sure safestrap defetes my perpouse of stream lining wanna try a customer from for the first time any body walk me through a safe way to proceed can't brick this ****er please
If the bootloader is locked, you won't be able to install a twrp or Cwm and you can only use custom roms that are based on a stock ROM.
