SM-G781B/DS Bootloader - Samsung Galaxy S20 FE Questions & Answers

If I purchase a SM-G781B/DS or a SM-G781B "should" the bootloader be unlockable or do I run the risk of it being permanantly locked?

Hi how are things
I have a G781B.
G781B
G780G
G780F
they are unlockable.
The only ones that would have problems are:
G781U
G781U1
G781V
G781W

So this next one might be a fairly stupid question, but my brain has not been at top form lately. I should have no problem with a "carrier" lock since the bootloader can be unlocked correct?

you can unlock and lock the bootloader.
if you use samsung pass and other related, you will lose that option.
you have the control you want in G781B
root, encryption, etc.

To unlock boot loader, buy an Exynos chipset version?

From what I have read, buying a US-based Note 9 (Snapdragon chipset), I will not be able to unlock the bootloader.
1) Is that correct?
If I buy an "international version" (Exynos chipset), I will definitely be able to unlock the bootloader.
2) Is that correct?

No, you can unlock the boatloader on both of these devices. However doing it will trip Knox.

Unless you are talking about the N9600, the USA versions N960U and N960U1 cannot be bootloader unlocked.

Edit: thanks for the info, but I found an eBay auction that gave me an IMEI and Ting said that the N9600 will not work on their network.

Does a *factory* carrier-unlocked Samsung S20 FE 5G have an unlockable bootloader?

It's said that U.S. carriers almost always lock down the bootloader of a phone permanently. Thus, if a phone is carrier unlocked at the *FACTORY*, ie. it is not manufactured for any specific carrier, is it safe to assume the bootloader would be unlockable? Would this apply to a Samsung S20 FE 5G? Thanks
I live in Australia. Just bought an unlocked (carrier) 5G version and successfully unlocked the bootloader.
Nope, not the US variant unlocked model
Yea I wish I knew that before I bought the US unlocked one.
But I saw in another thread talks of flashing EU snapdragon firmware to see if it lets us US unlocked phones have access to oem unlock

Tried it, and it doesn't let you flash. But hopefully someone can figure out how to bypass that.....

Question Bootloader unlock

I've been away from Samsung a little while, the S21 Ultra has tempted me back.
Can't see myself not tripping them Knox for long, but does unlocking the bootloader alone cause this to trip? Thought id unlock this day one so I don't have to reset if/when the flashing starts. I will be getting an unlocked international Exynos variant.
From memory, factory images through Odin wont trip Knox?
Thanks!!

Why are you getting the Exynos version if I may ask, Lots of people rather the Snapdragon.

Largely it is way easier to unlock bootloaders on Global variants so the Exynos while not better per say it won't hold you back much and will give a better unlocking process as in the U.S. at least many Samsung devices get locked down.

Easy..... No need to pay to unlock bootloader and lots more development of Roms.

Hi guys, it's since some years that I don't have a galaxy s (last was s7). Since S21 ultra seems very interesting I'm thinking about to buy it, but how is the situation for what concern bootload unlock and root? It's easy to unlock and apply magisk without drawbacks?

I'm not too knowledgeable with this kind of stuff, but if you look at how Galaxy S8/S8+ root went, there was a bounty thread with a lot of money and in the end, no one was able to unlock the bootloader on the Snapdragon phones. It was way too hard, so everyone had to give up. They did figure out how to root the phone, but you had to use an old development version of the OS, battery was locked to 80%, and you couldn't install Magisk.

Answering your original question, unlocking the bootloader (either selecting OEM Unlock in Dev. Settings, and/or long pressing Vol+ on the DL screen, does *NOT* trip KNOX.
KNOX is tripped when you flash a customized boot.img file, not before

Yeh thanks bud, as I thought.
When you root and install custom kernel. It will trip knox. You can go for Samsung galaxy s21 ultra other country variant. USA version and Asian version (may be unlocked bootloader) are different. You can try custom recovery.

A71 SM-A715F/DS and A-716U questions

is the unlocked A-716U rootable using magisk and does anyone think there will be development on it(ie Custom recoveries ? One last question one this specific model; assuming root is possible on unlocked would it be possible to get a carrier locked version (cost saving) and reflash firmware similar to oneplus's MSMtool?
lastly is the A71 SM-A715F/DS root-able with TWRP support?
Thank you
ps
I will also contribute to bounties
everyone is going to say/think "search the forum!!!" but unfortunately the posts available dont list specific model numbers when talking about successful root/custom recovery,.
U.S. variants usually can't be unlocked and therefore you can't install custom stuff like magisk patched files.
That used to be the case until recently that a person was offering bootloader unlock as a service to many 2019 and onward devices, as you can see here: https://forum.xda-developers.com/t/sampwnd-usa-model-bl-unlock-info-u-u1-w.4201689/
But, you would have to ask if the A71 is supported. It probably would need to be tested, but the owner of the thread was quite confident that it could be possible.

Oh okay, so there is no MSMtool like with oneplus devices where you can just change to international firmware? If so if there an international 5g version of the a71 (any a-series) with 5G? sorry the model/SKU's for samsung devices is confusing and there is an insane amount of them.

I'm sort of guessing that's the Odin equivalent of Samsung devices, not sure I've never owned a OnePlus device.
You can use Odin to flash different firmware on the device as long as it's the same SoC. For example, I've flashed Galaxy S9+ Unlocked firmware on my T-Mobile Galaxy S9+. One is variant SM-G965U and the other is SM-G965U1. However on this case, both firmware were US. One was unbranded U.S. firmware and the other was T-mobile branded firmware. I've also flashed Poland firmware on my Mexican A71, they're both model SM-A715F on this case.
I don't know if there's an international variant of the A71 5G. I guess you'll have to look that part up on your own. I think there is though.
The MSM tool enable users to take a carrier locked oneplus device and unlock it among other things. can odin unlock bootloaders ?

Not really. Odin can only flash firmware, either stock or custom (you use it to flash TWRP and then basically everything else you flash with TWRP).
And no, Odin doesn't do any bootloader unlocking, any unlocking is done with the device itself. But as I mentioned, U.S devices aren't unlockable out the box.

There is no possible way to do it... for free as of now. If you want to unlock the U.S. variant you have to do it via the paid service I pointed out and thats only IF it works (as I mentioned, its been untested on the A71)
In comparison, you can buy the F variant, turn it on, head to developer settings and select OEM unlock and then unlock the bootloader.
If we ignore the paid service, sampwnd, that I pointed out in my other response then it is impossible to unlock the bootloader of the US variant and therefore, impossible to root.

I'm not really sure about the cost as I've never used the service myself, but I know the person running the thread is very reliable

There are a few A71 groups on Telegram, you can just search with @A71 on there, most groups are public

Question T-Mobile version to Global... Best route currently?

I am looking for the best way to convert my T-Mobile model to the Global version... I'm guessing via Fastboot and fastbootd mode? I've seen a few threads on here but was slightly confused as some people said it worked and some say it didn't? Please advise
Same
Careful, there's no way back unless you pay someone shady. Make sure you are fully network unlocked, because the unlock tool doesn't exist on global
The best way is to buy a global version
Buy it? Is that a thing that happens now?

No. Check out the other threads on MSM work, it's not pretty.
I've retired my op10, don't have to deal with oppo anymore
Yeah, flashing away from TMobile is possible with the full Downgrade zips iirc. But there's no way back to NE2217, so be careful. I can confirm my NE2215 works great on TMobile but I bought mine from Best Buy, fully unlocked, global edition.
EDIT: Two people have Qualcomm crash dumped now in this thread, it seems the TMO variant (NE2217) does not like to be flashed away in traditional methods.
I'm sure flashing to NE2215 wouldn't harm service, but why would you want to when NE2217 seems to get similar support for now?

Dual-Sim doesn't work with NE2215 from what I know, that's an NE2213/1/0 specific feature. Although NE2215 has the contacts for it, I don't think you can actually use the dual sim. Pretty sure the conclusion reached was the 2215 doesn't have a second IMEI from Manufacture.
EDIT: Just googling "OnePlus 10 Pro Downgrade Android 13 to Android 12" You'll find the full rollback zips. There's 3, NA, INDIA, and EU.

Use NA in the US. But as the other's have said, you won't get dual SIM. If you have already SIM Unlocked your device and won't need to go back to 2217 for any reason, then go for it.
Is the process the same as other models?
If that is the case then why would anyone want to go back to a T-Mobile variant?
Surely the main benefit to change region would be to get timely updates and not be isolated with a rarer model.
I'm just curious as I've had carrier locked devices before and the first thing I did was to change it. In the end I sent my device off to get fixed (unrelated issue) they sent me the unlocked version for my country, I guess being rarer is prevalent not her on XDA but with oppo too.

As I've stated, if you didn't unlock your SIM from T-Mobile (these come locked), you will never be able to unlock it without TMobile rom if you end up on global.

So if the user isn't in the need to change sim carrier then that's fine then isn't it..
I'll ask again, is the process for changing region the same?

Yep.
If it's the same as the UK, the network has to unlock the phone for you to other sims, usually in the shape of a code you enter..
May be different in the US
Bootloader unlock is a code that you have to get from Oneplus (Token) and you have to have the carrier (T-mobile) unlock the network and they are very reluctant to do it. You have to have paid off the device and have had to be a customer for some time.

Then that would be required prior to changing region... I'm not sure why the region would be a requirement to unlock the device to other networks.
May be worth asking the method used for unlocking the device to other networks.
I got them to unlock my network while I'm still paying for the device, I don't want to rock the boat. I'm sure if anyone other than the guy who did it they would lock it down again.
