[Q] Help in unlocking bootloader of samsung galaxy S5

Hi Team,
I am trying to unlock bootloader of samsung galaxy S5, but not getting clear answer how to do. I searched a lot on internet but didn't found much. Observation i got from internet .apks are avilable to unlock bootloader of samsung galaxyS3 but not such .apk are avilable for galaxy S5.
Since fastboot mode is also not supported by galaxy S5, so fastboot unlocking method also not work here.
Please help to unlock bootloader of samsung galaxy SM-G900R7.

Can't install TWRP on SM-J700T1

Hey guys!
I am a little new to xda, but I've been trying to customize my Samsung Galaxy J7 (2016, metropcs) for a long time. I've looked through the forums to try to find out how to unlock my bootloader. I've tried the unlock bootloader guide but it's no use. Apparently, one user said samsung doesn't support fastboot anymore, only odin .
So instead, I've enabled oem unlock to unlock my bootloader. When I tried to flash TWRP onto my phone via. Odin, TWRP doesn't get installed. I've also used their app, no budge either.
I strongly suspect that my bootloader is locked. Can anyone help me?
Thank You in Advance.

I was going thru same turmoil when I watched a YouTube demo in desperation of a fix. Guess what My error was, I was pushing volume down button for twrp not up button. Use up home off to boot to twrp recovery.

Question Is the SM-A125U different?

Is my A12 (a125u) different and unable to be bl unlocked/rooted, etc? It has OEM unlock in dev options....?

Did you figure this out? Looking to do the same... Also can't find a firmware for it, please share what you did if you had success. Thanks!

Yes, the A125U has OEM UNLOCK in the developer options......you can turn that ON by going into : settings > about phone > software information ...and then tap BUILD NUMBER several times until you see that you have enabled "developer options". Then you go into developer options and turn on OEM UNLOCKING.
Before updating firmware recently OEM UNLOCKING was greyed out. But now I can switch it on. Now the question is, can this variant be properly bootloader unlocked and rooted. The known repository for downloadable firmwares for Samsung phones DOES NOT seem to have this variant firmware for download. And I wonder if that is required for this to be properly rooted.

Galaxy firmware has the firmware for this variant. I have the att version and I can't seem to unlock the bootloader. Holding volume up in the download screen does nothing. Any luck?

Bump, I have all same questions.... Anyone figure anything out?

Before I had tmo Sim unlock my phone the I set the oen unlock to unlock now its not there at all

Anybody rooted this yet ?

anyone know the interchangeability of the firmware between the a125u and other versions

I wish to know as well

What if the OEM unlock not showing how do you get it to show

I'd like to know this too. I believe the internal are all the same for the MediaTek devices. I got a SM-A125F for free and want to use it in the US. It looks like I could if I can convert it to SM-A125U or MS-A125M. I already bricked it once trying to flash U firmware and has to flash back to F

i was able to root this sm-a125u very easily... downloaded A125WVLS3AUL1 firmware (canadian unlocked) flash the full stock rom and was able to unlock bootloader as simple as holding down all buttons when going into download mode, it unlocked it that way and was able to flash twrp, magisk and its all good

I have a similar issue but vice versa. I bought a US version (SM-A125U1) only to find out months after that the dual sim option is locked and i think the only way to unlock it is changing the firmware. Now I need help to know what I can do to, please.

Thanks for the info.
-Was there an "OEM UNLOCK" option in the Developer's Options?
-What did you do in DOWNLOAD mode to unlock?

Thanks man but unfortunately I tried this as well, I don't have the third option for unlocking, all I have in recovery is cancel and continue, holding volume up doesn't do anything

Hello ? Can someone tell me at least if it's doable ?

Someone ?

I've been in the same boat for a couple of months now. It seems that Samsung does not allow this option in the UI (or anywhere else I can find for that matter) for Qualcomm versions. Hopefully someone will come up with a proper hack soon because the bloatware on s10e is just disgustingly invasive and desktop mode is definitely lacking compared with Linux alternatives.
