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.....

I have a note 8 on AT&t prepaid. The bootloader is locked. I would like to upgrade to the 9. Is there a variant that works on AT&t prepaid that will allow me to root? Unlocked phone are just carrier unlocked right? Will the unlocked Sammy still let me root?
Thanks in advance.

I don't use AT&T, but yes unlocked phones just mean sim unlocked. Not the same as bootloader unlocked.
U.S. models are bootloader locked so no root there. Exynos models and N9600 are bootloader unlocked. You would need to check the available bands on those models to ensure they match your carrier, or wait until someone on AT&T confirms
Though carrier and bootloader unlock are different subjects, if an S20 FE 5G is Samsung *FACTORY* carrier unlocked, can I assume its bootloader is therefore unlockable? If it is, where can I get the unlock code? Bestbuy, for example, is offering this phone with both carrier unlocked and locked versions, https://www.bestbuy.com/site/search...rue&iht=y&usc=All+Categories&ks=960&keys=keys
Further, can I assume if a model is carrier locked, then the bootloader cannot be unlocked to enforce the carrier lock?
My objective is to root the phone and also install TWRP. I have no plans to switch my carrier, T-Mobile, and thus a model locked to T-Mobile is fine as long as its bootloader can be unlocked since a carrier-locked one is cheaper.
My understanding is S20 FE 5G is based on the Snapdragon processor. Some have claimed Snapdragon is impossible to unlock the bootloader, but I assume they mean you can't do it if Samsung doesn't allow it. Unfortunately, I simply can't find a Samsung site where they would give out bootloader unlock code for approved models.
No you can't not unlocked the boot loader I went with unlocked version bc of bloat software on carrier phones you will never get to unlock the bootloader

Thread closed. 2nd post contains the answer to op's inquiry. Thread is no longer needed
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.

when you say "out of the box" do you mean there is NO possible way to unlock them or it takes a process?

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.

how much does the paid service cost and do you have a link? i didnt see you mention it before. also do you have the aseries discord invite or telegram?

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
so i got a s21 about 1 month ago and it's a exynos model and its canada variant, i want to root it but it does not have a oem unlock option in dev settings so, hwo could i root it?

Do you don't have a exynos that's a Canadian variant.
The Canadian variant is a North American snap dragon.
Have to unlock bootloader first then install magisk. See developer threads for bootloader unlock service only if it's on bootloader version 1. To check bootloader version it look in settings/about/software the number 5th from the right is the bootloader version. Your 991w should be a snapdragon processor. The exynos model is 991F and you can unlock bootloader for free you can get oem unlock to show up by following guides on google.
Sorry to just drop a question, but I can't find the answer. Can the snapdragon S10 SM-G973u1 bootloader be unlocked? If not is there another way to root it?
Thank you
Chris
HelloChris333333, just when you post on a forum the courtesy of saying hello. Yes you can root just with the firmware of your model S10 SM-G973U1 US model so not compatible with EU firmware.

I'm not sure that's true, but I would love to find out I'm wrong.
In my research, the SD phones cannot be unlocked unless you are on (and remain on) an older BL version. The last unlockable BL version was 4, as I recall... if you're running updated firmware you are likely on BL 6. Even on 4, the process was not free and once you did it you could not update to a newer version of FW without losing the unlock.
For this reason, I gave up on getting root/BLunlock on my phone... and honestly, I have not missed it. This is also why I have not seen much development of FW for the SD phones anywhere.
Again, if I'm wrong, I'd love to learn how it's done!
Hello meric57
Can you share a link to the firmware I need? I just bought this phone and there is no OEM unlock option, it is a US phone. If I cannot root it I will have to sell it and get another phone.
Thanks
Chris
I guess another question would be where can I get a S10 with the Exynos chip?
Thanks
Chris
Using ADB I keep getting "waiting for device" and then I find I need to unlock the bootloader. This crap is an endless circle.
U4 can be unlocked before , I can unlock it , Special engineering documents need to be made
I'm V6 nothing available. I bought a G973F instead. G973u1 going on ebay.
Exactly, there is really no root/unlock for snapdragon phones unless you're on a very old BL (and you have to stay there so you can't update). IMO, that's not "can be unlocked" even with "special" steps, particularly since most phones today will have newer BLs (even a year ago, I couldn't find a BL4 phone)... but, yes, it's technically true to say it can be unlocked, but only in very limited cases.
@Chris33333 For this reason, I get that you may want to go to the Exynos instead... I'm curious, if you're in the US, how does that work with carriers? Does it? I've found most US carriers refuse to activate phones that don't match their list of "compatible" IMEIs... I imagine an F-series phone won't be on that list.
I'm in the US using Straight Talk with T-mobile. I've had a Galaxy S5 rooted for years. With straight talk I can use AT&T, T-mobile, or Verizon. But this international phone does not do Verizon.
And StraightTalk will activate the F-series phone without complaint or issues? If so, that's great to hear... because I know VZ and ATT typically won't...
I haven't put the SIM in it yet. Still trying to delete all the crap off the phone.
Lol
