G920T root/custom goodies on the G920T1

Hey guys,
So I just bought bought a G920T1 and I am aware that it is the same hardware as the G920T with a few software differences (missing download booster). Knowing this, is it safe for me to use the root methods/custom recoveries/custom firmwares of the G920T on my phone?
Thanks

Yes. And by custom firmwares I assume you mean custom roms

Yup, they are exactly the same phone. So use Unikernel to root, TWRP for recovery, and firmware of choosing.
One thing tho is if you wanna use the unlocking method with Metro which use codes. Then don't flash any TMO modem and bootloader as you will lose the unlock. Just update them to lastest 5.1.1 from sammobile or OTA if you need to. Other then that you should be good to go.

I bought the phone off swappa and it was listed under the T-mobile S6 section, but I noticed that the model number in the pictures was G920T1. I'll probably ask the seller how he unlocked his phone. So flashing a custom ROM should be fine, right? Based on my previous experience flashing my older S3, flashing modems were usually a different .zip than the ROMs and I don't really remember all too much about bootloaders.

Yeah flashing custom rom is fine as they don't include the modem nor bootloader. It's just that most newer roms require you to have the lastest bootloader and modem for best experience. Sorry didn't mean to confuse you more, but G920T and G20T1 are the same phone. Some people just swap firmwares between TMO and Metro as the G920T1 is easier to unlock. I have the same version G920T1 and bought code off of ebay to unlock easily.

Alright, then can I upgrade to the newest Metro bootloader to keep my unlock and then install the newer ROMs? Or would I lose my unlock that way.?

Hello again, about to get my S6 soon and was wondering if you could point me to some root methods that would work without breaking fingerprint scanner or tripping KNOX. It's been awhile since I've been back in the rooting scene and was hoping you could point me in the right direction. Also, if I want to keep my unlock and upgrade to Tmo 5.1.1 stock, I would flash the Tmo ROM with a Metro bootloader?

[HOW TO] Flash U1 firmware to U device

First of all, thanks to Raymonf (I dont know his XDA Username) for making these Odin files. This new version of modded Odin allows for flashing custom and official tars AND also compressed binaries, which Samsung will be using in all Odin firmwares from Oreo on.
Oh and doing this doesnt wipe data if you do exactly what I wrote below.
1. Download your devices firmware from below
2. Enable USB debugging by going to settings > about phone > software info > click build number 7 times and enter your password
3. Open command prompt on your PC and type adb reboot bootloader
4. Open odin and select the AP, BL, CP, and HOME_CSC file in their corresponding locations
5. Start it
6. You are there!
To go back, do the exact same thing with the U firmware files!

Thank you for this. In all of the download mirrors for the s9+ the free download is unavailable. Is it asking to much to upload to a site that will offer free downloads?

The modded/patched Odin has the model-ID and SHA hash check disabled, therefore allowing you to flash an unbranded "U1" firmware onto a branded "U" phone and vice versa.
As of now this works on most US Qualcom (QC) models, but an increasing number of international Exynos (EX) models now include a new RMM security which prevents this kind of cross-flashing unless you first disable the RMM, by flashing an RMM-Disabler package through TWRP.

Probably gives better chance to root huh?

What I'm not clear on is: after I flashed my factory unlocked s9 to the VZW U firmware to see if I could get video calling to work (it didn't) then flashing back to what has been described as stock U1 ARBG firmware, in my about phone it still says VZW/VZW/XAA. Is this set by the SIM. Will this only change when I put a different carriers SIM card into the phone?

Question, before i dive in...
My UICC is locked to Sprint right now (damn 50 day limit) and I was wondering, if I flash this U1 rom, would I be able to edit the APN? Has anyone else done this?

That's correct, the unbranded "U1" firmware sets the carrier parameters based on every different carrier sim card inserted.
Don't worry about the VZW/VZW/XAA, for all intended purposes the phone acts as Verizon phone.
It's just a flag, but if you can't sleep over it then do this while rooted:
adb shell su -c echo "VZW" > /efs/imei/mps_code.dat
adb shell su -c echo "VZW" > /efs/imei/omcnw_code.dat

Flashing the unbranded "U1" firmware will neither unlock the network nor the APN settings if you keep using a Sprint sim.
On the other hand, if you unlock the network and insert an AT&T or Tmobile sim then you should be able to edit the APN, but then again you don't have to edit it because it gets set automatically based on the type of sim inserted.

Thanks a lot, quick question, i have an at&t "U" model, manage to install the U1 software (wanna get rid of all the at&t apps), everything its working just fine, but when an update comes to the U1 model, can i install it the regular way on odin, or do a need to follow this steps again??
here's the link i use from another post to dowload the system a bit faster: https://androidfilehost.com/?w=files&flid=257047 greatings to the author.

Your Milage May Vary. I have a factory unlocked S9. When you flash firmware there are risk, don't hold me accountable if your Knox gets tripped some how. People hose their phones in flashing accidents then say someone gave them wrong info.

I wouldn't blame you lol, yes I know there's a risk. But you have stated earlier that you flashed a firmware and it didn't trip knox, so I'm wondering if you flashed a carrier firmware "U" on your SM-G960U1 device..

I'm glad to report that after flashing the Sprint firmware on my unlocked S9+ worked no issues and knox was not tripped. Now I've noticed that even though the Sprint splashscreen didn't show up at boot, while in setup the phone did detect the exact carrier I was on (Boost Mobile) and the phone showed the Boost Mobile splashscreen upon reboot and all the Boost Mobile apps as well as some bloatware loaded onto the phone as if it were a phone I purchased through them.

So if I flash my tmobile device to the u1 firmware can I then root my device and put twrp on it?

Is any root method available for the t-mobile version?

Is it possible to flash the n9600 firmware on an n960U1?

I'm hoping to get root on this phone and I remember reading somewhere that bootloader unlock was possible on the n9600 model. I have the n9600 firmware and the patched Odin on my computer and was wondering if anyone had tried this or if this phone would even boot after being flashed with this firmware. The n9600 from what I understand is a Snapdragon model and the only difference is the addition of a second Sim slot.

you do know the phone is almost 1 year old right?
if the n960u still dosent have root, its for a good reason.
if it were so simple as to flashing an other firmware, i can guarantee you the snapdragon dev thread would be flooded with roms and stuff instead of having 2 releases.( 1 recovery, 1 rom)
to me implied logic tells me that the above should have been self evident.
sorry if i pass as a realist.

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.

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.

Is it possible to change S20 FE G781B to G781U?

I was wondering if it is possible to flash G781U firmware on G781B since they have the same specs.
would love to hear what you think (or know).
Thanks

I'd keep the B model as it is as it can have it's bootloader unlocked. if you're taking that phone to the states someone would gladly buy it off you as is.
if you wanted updates after moving they could easily be manually downloaded and flashed. if you concerned about frequency bands then maybe there are ways to tackle that.

not sure to be honest, I suspect that the existing bootloader would generate a fail error before or just after you started but I can't say for sure.
if it did fail after starting to flash you'd need B firmware on hand to make it useable again.

Trying the same but switching from 781W to 781B. Had no success so far. Odin is failing to flash. At least so far I did not brick the device. Any advice is welcome

tried, but so far without success. I'm missing the "OEM unlocking" option that is stated in the manual. Trying now to update to latest firmware. Maybe this will enable the unlocking option.

hm... I just learned that there may be no OEM unlocking option on my snapdragon device. There really is a lot to consider... Somehow OEM unlocking does not work on snapdragon devices from north america. In latin america although this might work. I don't really get what the point of all this is. [some sauce]
edit: maybe it is possible to unlock it through fastboot, but so far i only get a command not found error when using ´´´fastboot oem unlock´´´

Yeah, from what I understand devices with U at the end of their model number are missing the OEM unlocking option. I think its stupid to only block the option to some of the world, I mean either block it completely or dont block it at all.
Maybe it is possible to change your model to W and then unlock it, I im not wrong you are supposed to be able to flash W firmware on your U device without unlocking the bootloader.
Just make sure you download firmware with the same binary number in the baseband (the fifth number from the right)

Unlike the original poster I am trying to go from SM-G781W to SM-G781B (or anything else that has german language).
To my understanding Samsung does this as the carriers in North America are requiring it, but not sure why.
