Im curious about tthis myself, but ive kind of resignes myself to the fact im probably goong to have to get an s6 directly from samsung that allows the option to unlock the bootloadr out of the box. There is a new "security update" from verizon though, im curious about what it actually patches before I update.

Sorry for the double post, but I need information by those much more experienced.

So thanks to the 3D patched Odin, my T727V is now a T727U. So basically It's like I bought the thing from Samsung with no carrier bloat and all the nice little things like calling and texting through the phone that Verizon blocks and things like that. Things is I still have no OEM unlock in the dev options, so now I have a few options. Apparently the remote OEM Unlock enable in Pie is CSC based? So obviously the csc is still registered as a VZW, so does that immediately kill the chances and thus it would be a waste of time to wait for the RMM lock (which I'm pretty sure I would have triggered), right?

Also, even though transforming the tablet into a fully featured unbranded is really nice, I still would love custom firmware, and I'm at a catch-22. If OEM Unlock is governed by the csc or imei and not the firmware, I really have no way to change either without root, which I can't accomplish without custom recovery, which of course I need OEM unlock. A question and a tidbit though, question being why I can flash between carriers and unbranded, but I cannot flash to say the Turkish T727 firmware. The interesting tidbit being in the recovery logs for the T727U firmware flash I did, one of the build.prop properties that was set at flash by the firmware is "ro.oem_unlock_supported = 1" This does NOT appear when flashing the Verizon firmware.

Edit: Welp. To any other Verizon S5e owners, flash the T727R4 US cellular firmware. OEM Unlock toggle available immediately.

Where did you find the T727R4 firmware?

Where did you find the T727R4 firmware?

Frija! Use CSC code USC on auto mode, boom. Now it's US cellular, which did not like my Verizon sim card at all, so here's a really short summary and links to much better help to do all this (knowing all risks and pitfalls etc.) and end up rooted and your Verizon sim still functioning.

Few things, one this was written up with a Verizon s5e in mind, I don't know if the PITs are different for the other carriers, so this one operates with Verizon's in mind. Two, you MUST have a patched Odin. Also standard advice of backing up everything before hand, and finally, I was dumb and had my SIM card in during the whole process. I'm not sure it had any ill effect but if you want to be super safe, go ahead and keep it out until you're on T727U firmware.

Pre-note: I have no clue if you can substitute t727v for t727u in the following write up. I wanted all traces of Verizon out of my tablet when I was figuring how to enable the Bootloader unlock. We're using the R4 BL files for the whole process so it may or may not effect anything as far as that goes.

1. Do a standard flash of the R4 official Samsung firmware. (You might have to use the us cellular pit for this flash. If so remember to use either the U or V pit for step 3.)

2. Follow AHE_XDA's fantastic guide, right now only the parts about unlocking the bootloader.

3.Once that's done, flash The AP of T727U firmware, with the cp and csc ofT727V Note: Not the BL. We do not flash anything to the BL after the R4 firmware in step 1.
Addendum: Use the Verizon pit (usa_open) when flashing to t727U the first time if you get a "could not open file on line ****" error from odin.

4: Follow the rest of AHE_XDA's guide on rooting and there you go!

I hate that, that was the part that was no hassle for me so I dont know where to begin...I used the December R4 us cellular firmware, if that helps at all. The same thing that unlocks the toggle should have given the long press up option in download mode. You started with a US T727 Verizon model, right? Now I had changed it to t727U first, maybe that had something to do with it?

It was cuz i was on a newer fw version for R4 (feb4) i downgraded to the Dec one and i now i have my bootloader unlocked (shows in dev settings, get notification at boot, and says oem lock off in download mode) but i keep getting a error about "only being able to flash official firmware versions (vbmeta)" . turns out this is from my KG Status being PRENORMAL instead of Checking. you can check this in download mode as well. did you have any issues with that or kknow what i'm talking about? there are guides that say to do things like roll the date back on your phone manually then check for updates but it doesnt work

also i'm a little confisued about the end of your directions. I am not a Verizon Subscriber i bought this 2nd hand for a deal i am on TMO (not planning on really using data on thin atm but still) Am i correct in thinking after you flashed R4 BL AP CP and CSC, then booted into the R4 firmware and went through initial setup, then reboot to recovery to unlock bootloader and then flashed the t727u AP, left the R4 bootloader, and flasshed VZW CP and CSC? i cant seem to get mine to boot if i do that i get hash check errors when it tries to boot and spits me out into download mode. if this is the case do you remember or can you check the exact versions of CP, AP, and CSC you flashed? right now what i did was flash all R4 tars to go from 727v to 727r4, went though setup and verified i have oem unlock option in dev options then rebooted to download mode and unlocked bootloader THEN i FLASHED 727u versions of AP CP and CSC since my error with the vzw ones i mentioned earlier. Last question. should i be putting my sim in? i notice when i flash the U firmware i get a message about carrier settings update and it makes it reboot

thanks for replying btw

could you check something for me real quick? could you boot to download mode and look for "KG STATUS" and tell me what it says. i think my issue is somewhere in the processs of flashing the different firmwares KG gets set to "PRENORMAL" which acts kind of like a secondary bl lock. if i restore to the oldest vzw firmware i could find (june24) it puts it back to "CHECKING" which is good but i loose bootloader unlock in the process obviously thus the catch 22.

See, as soon as I switched from T727V to T727U I stopped even seeing kg status in download mode. In my original post in this thread I thought that meant I had tripped it. I really have no clue why just switching to unbranded firmware would make that difference either. I just lucked out on the magic cocktail to unlock Verizons bootloder, I was kind of hoping it would be easy peasy for others. Like, my poor tablet went through odin every day for a straight month.

E: Just saw your edit in your post. I'll have exact firmwares I used asap. In the meantime, my hotspot worked just fine on the unbranded CP and CSC, maybe try that?

I'm really scared of bricking my LTE AT&T tablet if I flash the only firmware I was able to grab.

Any way to find the specific stock firmware for my sm-t727A? I've tried Frija, and went all over google to no avail; I can only find other stock firmware.

If I just want to switch to sm-t727u firmware from sm-t727v firmware without rooting do I need to go through the extra step of flashing the us cellular version first?

I get to the unlock the bootloader part but then when I go back in and try to flash the U software according to your instructions, it doesn't work. Could it be that the software has been updated since the instructions were written and it won't work now?

I have tried every version of Patched Odin and followed these directions to a T. I even went back and tried other things and can't get this to work. If someone can help me get the U software to flash on my SM-T727V, I got $20 I'll Venmo or Zelle you.

I am trying to copy your process with a Tab A 2019 unlocked, but Sprint variant with no success so far. I have bricked it a lot, but it doesn't seem to want an unlocked firmware for the same model :(. I haven't tried flashing it's bootloader though, out of fear of bricking it ( I have unlocked its bootloader already).

Hey guys, just found the thread. Anyone know if an unlocked SM-T727A can be OEM unlocked? I mean the bootloader. The option is always missing no matter how many time I try according to the tutorials, which makes me doubt if a branded S5e doesn't even have this capabililty. Perhaps that's why I am here seeking a chance to flash it to an SM-T727U. Thanks for anyone who replies.

Ok so after three months I turned my mind back to this topic again. And yes, I struggled for a couple of hours overnight last night and got the ATT T727A flashed with Lineage. There are a few tricks: First, the USC R4 firmware can be flashed, with the modified version (3B) of Odin, which bypasses the SHA256 error check; Second, when the USC R4 firmware (latest for now is Mar 2021 version, Android 10) is flashed, the start logo changes from slick ATT to full screen big fat US Cellular. Need to wait for a few minutes and let it do its work. Through this flash, user data will not be lost. Third, the USC R4 version does have OEM Unlock automatically present and all it needs is to flip the switch, then go to download mode to unlock the bootloader. This will erase the user data. Fourth, from then on it's all standard procedures to flash any third party roms like LineageOS with MicroG pursuant to their instructions. Four hours work made a good result, and the cellular data is usable without problem.

PS: the concept of timed OEM unlock switch (a week after factory reset) is wrong. It's non-existent so do not waste time on it. Just straigntly flash the USC R4 Version. To flash other roms like Lineage, it would be better to download the Odin with their specified version to prevent hiccups.

    Good news everyone! o.o My SM-T727A is now running LineageOS! Here are the step by step instructions:

    PLEASE NOTE: After the whole process is complete, my tablet states it's an SM-T725 in the Android About screen because you need to flash the US Cellular firmware as a workaround to unlock the bootloader. Also, when restarting the tablet, a screen appears that states "This tablet's bootloader is unlocked and its software integrity can't be verified." Then another screen states "The tablet is not running Samsung's official software." Then the LineageOS splash screen appears and the system loads. :) The information below is provided for your informational purposes only. Proceed at your own risk.

    DOWNLOAD US CELLULAR FIRMWARE
    Download Frija at https://forum.xda-developers.com/t/tool-frija-samsung-firmware-downloader-checker.3910594/
    Extract the zip file.
    Open Frija.exe as an administrator.
    Enter the following information into the program:
    Model:SM-T727R4
    CSC:USC
    Auto:checked
    Click check update.
    Click download and save.
    My Frija downloaded: SM-T727R4_2_20211029161118_ijtwqlgpl4_fac.zip.enc4

    FLASH FIRMWARE
    Download a patched version of Odin at https://forum.xda-developers.com/t/patched-odin-3-13-1.3762572/
    I downloaded "Odin3 v3.14.1_3B_PatcheD.zip".
    Extract the zip file.
    Open "Odin3 v3.14.1_3B_PatcheD.exe" as an administrator.
    Power off the tablet and boot it into download mode: with the tablet powered off, hold Volume up + Volume Down + Power. At the prompt, click the button that on the onscreen instructions that correlates to “Continue.”
    Download and install the newest Samsung drivers "SAMSUNG_USB_Driver_for_Mobile_Phones.exe" from https://developer.samsung.com/android-usb-driver
    Connect the tablet to your computer using a USB cable. It should appear in Odin above where it says "ID:COM" as something like "0:[COM3]" or "COM0".
    Load the BL, AP, CP, and HOME_CSC files from the US Cellular firmware folder that you extracted into their respective places in Odin. Ignore the other "CSC_..." file.
    Click start. A progress bar should appear at the bottom of your tablet screen.
    WAIT until Odin displays PASS! on the top left and "All threads completed." in the log.
    Your tablet will restart automatically and show the US Cellular logo.

    UNLOCK THE BOOTLOADER
    Go through setup wizard inputting the minimal amount necessary, skipping as many things as you can but do connect to a Wi-Fi network during setup. This allows the tablet to adjust the date/time automatically.
    Once at the Android home screen (YAYY!), go to Settings (swipe down from the very top and hit the gear icon) > About Tablet > Software information.
    Tap on "Build number" until Developer options is activated.
    Go to Settings > Developer options.
    Tap on the switch next to "OEM unlocking" and tap "Turn on" at the prompt.
    Tap on the switch next to "USB debugging" and tap "OK" at the prompt.

    FLASH LINEAGEOS
    Continue with the instructions on the LineageOS site after the "OEM unlock" step.

    Thank you purplerose1414, Wieczorkiewicz and everyone on this thread for your help.
