Is it possible to flash dev-edition firmware on our s5's to get the bootloader unlocked? No matter the cid/emmc of the device?

if its locked bootloader cid then no the bootloader will prevent any unsinged firmwares to be loaded.
it would probly hard brick your device trying.
I may be wrong but this is how its been for most of time

I am sure, people did that the day the Dev S5's firmware was made available. The reverse however is most definitely true, several people ended up locking their Dev S5's bootloader by flashing regular S5 firmware. They weren't able to get them unlocked until when the exploit for CID 15s was discovered and released.

Alright, so as the title says, I'm not asking if the bootloader is unlocked. I know it's not and its quite depressing. Anywho, I was curious what the process of unlocking is. If someone could explain in detail, that'd be awesome. I read somewhere there's something about brute forcing a SHA-256 key or RSA-1024.
If you could explain, I'd love to know!
Thanks!
Don't know about unlock process, but I found some interesting video. Some guy changes imei on g935v. After the process there is unlocked padlock at Samsung boot logo. Does it means that bootloader unlocked?

Or look here some guy claims that he flashed g930v to g930f with UAE version . And again unlocked padlock.

When the guy changed the imei did he have to root?
If so that's where the custom padlock came from most likely.
The padlock often means custom binary, which means root/non stock ROM. To see if the bootloader is unlocked you must boot to loader (vol down + power + home? Maybe vol up). There it will tell you if you are unlocked. Cool videos and thanks for sharing!

Guys this g930v to g930f is a really big deal, right? Doesn't having g930f signify the fact we can unlock the bootloader? Or does it have to be the exynos proc?

Flashing the F firmware is basically like flashing the U firmware. The F's stock phone is Exynos though meaning it's bootloader unlockable. The F firmware itself won't unlock the bootloader unfortunately. I see what you are getting at though. Thanks for taking a look!

Yes, but the F isn't just a different firmware. It's a different phone. Nothing you ever do will change our phone into the F. And you can never flash the F firmware on our phone (or vice versa).

I was looking into buying a J727V, it looks like the bootloader may be locked, obviously this stops me from putting in my own custom rom, can anyone confirm?
Last time I bought a (I think) Note 4 I had to get a developer version so that the boot loader was not locked in order to put on a custom rom.
If it is bootloader locked is there a different version of the J7 that I can get that I can use on Verizon?

yes all carrier bootloader is locked you need to buy unlocked phone or i think there are some unique processes are available also on xda to unlock boot loader but i am not confirm.
Have s8+ on HK firmware. Cant flash anything custom due to blocked binary by frp. No oem in dev options, removed google account and samsung account, unlocked BL via CROM. Please help how to fix it. Thanks
It's a Snapdragon 835 device, which means the bootloader cannot be unlocked, just like the US carrier variant bootloaders. If your bootloader really was unlocked, FRP wouldn't be blocking custom firmware. Exynos bootloaders can be unlocked from dev settings, but not Snapdragon bootloaders.

You're saying that you unlocked the BL via CROM, but it's not unlocked if you can't flash custom firmware in download mode. Having a locked bootloader means that flashing custom firwmare is blocked, exactly what's happening here. If the BL can be unlocked, just unlock it, I don't get what the problem is?

explaining again.. CROM told that bootloader is unlocked( i dont know any other tools or ways to unlock bootloader on that device), but i still getting message, that it is blocked by frp, which means that something is not setted up like it should be. THat is why Im asking here fo any way to fix that issue on current device.
I'm also having this problem. Upon trying to either install TWRP 3.2.1 or chainfire's root file via ODIN, I get the error "Custom Binary (recovery) Blocked by C-ROM". I have tried to run the CROM service apk, versions 1.0.4, 1.0.6 and 1.0.7; however, upon opening, they all freeze and close, which seems to mean they didn't do anything. When going into download mode after running the CROM Service app, CROM Service is on and, when trying to install via ODIN, I get my errors.
I have the Samsung Galaxy 8+, G9550, 128gb and 6gb rom, Snapdragon Variant. I have found articles saying that the 9550 variant can be rooted since it's the HK version, although some say that it needs HK firmware. I'm on the AQF7 build.
Any help is greatly appreciated!

There is no way the bootloader can be unlocked currently, the decision was made by the carriers to lock the bootloaders I think as all exynos versions can so there has to be influence from somwhere, that's why the only other sd that can is the Chinese variant.

It doesn't really matter, you'll be using a carrier one way or another. The reason why I say American and Canadian carriers is because China has the snapdragon variant and there bootloader can be unlocked, so influence is coming from somewhere other wise the Chinese variant would be locked also.
It's been so long since I last rooted my phones, maybe 6 or 7 years now... I don't even know where to start. Is TWRP still the go-to method for rooting these Android devices?
I couldn't find anything specifically for the T-Mobile variants, dunno if that's been done yet.
Thanks,
Nick
Your bootloader is locked and cannot be unlocked. No root or TWRP available.

Is this device always going to have a locked bootloader? Flashing an unlocked firmware wouldn't change anything? Im new to samsung and have been out of the rom game a long time.

These devices will always be locked down. The last U.S. Samsung phone to get root was the S9, the S10 line are locked up tight. Flashing unlocked firmware just makes your phone carrier free so you can use it with any carrier, it doesn't unlock the bootloader.
What phones are best for modding these days then? Just came from a Pixel 4 XL and it had a locked bootloader plus tons of hardware issues that ended in me getting this phone
I would say a One Plus phone is probably the most versatile as far as modding goes these days. You could also get an exynos S10 variant which can be rooted and custom recovery installed.
