I really want to flash a recovery (clockwork mod) through Flashify however many tutorials say that the Bootloader of any phone must be unlocked in order to flash recoveries through Flashify. I would like to know if the Bootloader is already unlocked or if it is possible? Thanks.
Also it is running Android version 5.0.1 Lollipop

Hi,
I was planning to flash TWRP on my S6 on 5.1.1 and I see that the OEM unlock option in the developer options is missing. I can vouch that this was there when I was updating to 5.1.1 and even when I installed a custom kernel. Just wondering what my options are. Is it safe to flash or do I have to flash the firmware again to restore the functionality.
Just bought the galaxy s6 edge. I wanna root it but there is no "oem unlock" option in developer mode. Does this mean that the bootloader is already unlock or it just cant be unlocked?
Any solution to this?

I have an g920F s6. There is in developer options no oem unlock option in my stockrom 5.1.1
To root your phone use unibase v8 kernel flash this file via odin 3.10.6. Its for all models of the s6 except sprint and verizon.
When the phones reboots your rooted. You can flash twrp recovery via flashify

I used Odin 3 to install TWRP and it went without a hitch. Guess not having this is not a big issue at all.
Samsung G920F on nougat 7.0 QEG also dosn't have oem unlock button in developers option but i used odin 3.12 and flash correct recovery file it worked (means Bootloader is still unlocked on Android 7.0 for G920F) and do not forget to flash root also.

G920f variants come with unlocked bootloaders by default
I want to install the XtreStoLite Deo-Mod Edition 2.4 rom, since i'm running 5.0.2 and that rom is a 5.1.1 mod it says i must flash the corresponding bootloader for my device (Galaxy S6), my question is: do i need to have an unlocked bootloader in order to successfully flash the required bootloader for that rom?
Hey everyone, I've been researching for days, trying to figure out how to Unlock my bootloader on a 4.2.2 OS d2vzw(Verizon SGS3) SCH-I535. it seems the only way I can start flashing new roms( specifically CM 12.1) is to install a custom recovery such as TWRP or CWM, but it locks up my recovery and I end up flashing the stock 4.2.2 over and over again. are there alternatives ways to flash roms? is it impossible to unlock my bootloader on a 4.2.2? is there a way I can downgrade my bootloader? help please nothing is working and I can't find current information....Thanks.

I'm assuming you mean 4.4.2 or 4.1.2. There is a huge difference between the two.
If you are on 4.4.2 you do not have the option to unlock the bootloader.
However if you are on 4.1.2 you do have the option to unlock the bootloader. There never was a 4.2.2 update for the VZW S3.

http://www.mobiletechvideos.com/samsung-galaxy-s-iii-s3-bootloader-downgrade-service/ I should start a thread with this LOL. This guy is the only guy I know of that can do it. It's done by soldering a jtag in 3 spots all within millimeters of each other. I've sent a bunch of business his way and never saw a bad review
Hi to All!: I'm new to this forum and you may consider me a newbie, willing to learn from you and share my experiences in the near future. Just recently I managed to root my Samsung Galaxy S5 SM-G900V running Lollipop latest release (OK3) following this tutorial (thanks a lot to jrkruse for that!!). Now I'm trying to install a Custom Recovery, I tried Safestrap (Safestrap-KLTEVZW-NCG-3.75-B03.apk), ClockworkMod (philz_touch_6.41.6-klte.tar) and TWRP (twrp-2.8.7.0-klte, tar & img versions) and this is what happened:
----Safestrap App installed successfully but failed to install Recovery.
----ClockworkMod (Philz Touch variant) failed to flash with Odin.
----TWRP succeeded to install via ADB shell, replaced Stock Recovery but gave this error:
''RECOVERY BOOTING...
RECOVERY IS NOT SEANDROID ENFORCING''
I ended flashing Stock OK3 to have at least Stock Recovery again!, it's known OE1, OG5 and OK3 updates prevent downgrading, I want to downgrade to 4.4.4 to solve some wi-fi issues I've been having since Lollipop updates.
Some help about this subject will be very appreciated!!
Thanks a lot in advance to all members of this awesome forum!!

On OK3 the bootloader is locked. You cannot downgrade to 4.4.2 or 4.4.4 or any other previous version. You also cannot install custom recoveries like ClockworkMod or TWRP. You are relegated to Safestrap or FlashFire as discussed in jrkruse's threads.
You can ONLY use SafeStrap. TWRP and Clockworkmod cannot load because we have a locked bootloader.
You must flash a kitkat kernel to boot into safestrap, which I gather you didn't do. Then when you're done in Safestrap, flash a safestrap-flashable lollipop kernel BEFORE EXITING SAFESTRAP to boot back into your ROM.

Thank both for your replies!, let's see if I misunderstood something: flashing NI2 Stock Kernel with Odin will give the possibility to boot into Safestrap and flash zip of Stock NI2 ROM (4.4.4) or will I remain tied to OK3 even if I flash the KitKat Kernel?

I'm just curious about the whole flashing a custom recovery part you were talking about..
It let you flash one?
Normally I'd just shrug a thread like this off but when you said you tried to boot into recovery and saw
Code:
RECOVERY BOOTING...
RECOVERY IS NOT SEANDROID ENFORCING
that means it actually let you flash a custom recovery.
So my real questions here are, in download mode, does it say Knox 0x1?
And/or after you tried to boot into twrp, did it say "set warranty bit: recovery"?
This part makes me curious because on a locked bootloader, we shouldn't be able to flash a custom recovery.
Or maybe we can and just can't boot into it.
I haven't looked into this much because I've always just accepted that a locked bootloader means we need to use SS or FF and can't flash custom ROMs like CM.
Although I am curious what makes Samsung phones different than my old Droid Bionic. It has a locked bootloader and can only use Safestrap but it can still flash CM13 in a non-stock ROM slot. Why can'take we?
Perhaps I should call someone like @jrkruse in to see if he can clarify or if he knows why.

Because on other phones they had ways to trick the phone into letting a custom kernel be flashed. These ways dont work on S5. Also Rom slots dont work on our phone either unless you go back to kitkat, but you were still booting off of main kernel,so still no go

Hi!
I have a Samsung Galaxy SM J100H with KitKat 4.4.4 that I would like to unlock the bootloader on.
The only tutorial that I can find online tells me that what is given will only work for a stock android ROM but not a custom like my Samsung touchwiz.
Does anyone have any suggestions?
Thank you!
Sadly to see you've got no reply from anyone on here! I am also having the kind of your phone and I really need to unlock bootloader. Although I already have root on it.

I don't think it matters that you're on a custom ROM, custom ROMs don't change your bootloader, it still has the stock bootloader you had before you flashed the custom ROM.
Either way, you can flash back to full stock via Odin then follow the instructions you found. Then flash TWRP the flash SuperSU.zip in TWRP to root, then you can flash custom ROMs.
