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

---------- Post added at 05:02 PM ---------- Previous post was at 04:56 PM ----------

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
[Samsung Galaxy Tab S5e Questions & Answers] albinoman887:
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.
[Samsung Galaxy Tab S5e Questions & Answers] purplerose1414:
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.
[Samsung Galaxy Tab S5e Questions & Answers] Wrightperspective:
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?
[Samsung Galaxy Tab S5e Questions & Answers] Wrightperspective:
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?
[Samsung Galaxy Tab S5e Questions & Answers] Wrightperspective:
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).
[Samsung Galaxy Tab S5e Questions & Answers] Wieczorkiewicz:
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.
[Samsung Galaxy Tab S5e Questions & Answers] Wieczorkiewicz:
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.

Help me ola if u r there. I have same t727a of att live outside The US. I just want to skip Att block and use SMS app, so flash Usc t727r4 via Odin patched is enough for me? And if i want update from android 9 to 10 i just do same thing with Q firmware?

Thanks a lot, I have followed your tutorial to the dot with my Samsung T727v.02 official firmware that was full of bloatware, and it worked perfectly.

Just a note for future readers: the "HOME_CSC" goes into the "CSC" field, still, and every time you load one of those files, there is a loading time (checking the checksum), just be patient…

Also, as usual, the first time the tablet reboots, it takes quite a while.
[Samsung Galaxy Tab S5e Questions & Answers] tbtbtata:
Just FYI, the exact info about this tablet (in French, sorry, but the serial and version numbers are universal :-))

And, just one last note: for some reason I was never able to make the recovery.img given by lineage at

https://mirrorbits.lineageos.org/recovery/gts4lv/20220122/lineage-18.1-20220122-recovery-gts4lv.img

So, I have used twrp instead, the version from

Nevermind, it turns out I had accidentally booted into the stock recovery from Samsung and that is why it was falling when I rebooted and reflashed TWRP and booted directly into that, it worked.
[Samsung Galaxy Tab S5e Questions & Answers] taney:
Thanks so much for all your help, @purplerose1414! I was able to convert my SM-T727V to US Carrier and install Lineage 20 (Android 13). Everything works EXCEPT receiving and making calls. I can even send and receive text messages when I throw in my mobile SIM (T-mobile). I'm assuming it doesn't work due to voLTE. I tried reflashing US Cellular firmware but I'm assuming it doesn't work that way since it's limited to data?

Anyways, I'm very grateful! Thank you all!

I am getting stuck trying to install a custom recovery.

I installed the US Cellular Firmware, and am able to check OEM unlocking & USB debugging, but when I boot into download mode and try to install TWRP it says blocked by OEM lock.

Note that I am trying to do this from Linux using "./odin4 -a twrp-3.7.0_9-0-gts4lv.img.tar" so maybe this doesn't work the same as the GUI / windows version?

####

Nevermind, I didnt follow the instruction exactly. I just used "adb reboot download" which never showed my the option to OEM unlock. When I did it the physical way I got the option to OEM unlock =]
[Samsung Galaxy Tab S5e Questions & Answers] josh4trunks:
I guess I still do have an issue. Patched Odin is only available for Windows. Any way I can flash the recovery from linux now that my OEM is unlocked?

####

I am able to access download mode, from a Windows virtual machine where I can run the PatcheD Odin3B.

But now whenever I try to flash AP I get FAIL and on the tablet it says "Only officical released binaries are allowed to be flashed"

Any idea what I am missing?
[Samsung Galaxy Tab S5e Questions & Answers] Jobudden:
im thinking about getting this tablet to run in my truck i need an lte version.

what im gathering by reading this is that i can get the verizon unlocked model. flash a different os then install a root?
[Samsung Galaxy Tab S5e Questions & Answers] josh4trunks:
It took me a few hours, but probably would be simplier if I had a normal Windows machine (not Linux) to run Odin. But yes, you can get it running LOS, rooted with Magisk, and it still recognized the Verizon (or any) SIM I had in there. I didn't test SIM functionality but I think it should work based on other's experience.
[Samsung Galaxy Tab S5e Questions & Answers] Jobudden:
Thanks for responding! ive never rooted a device. but i see the leanage os seems to be pretty popular. i really hope to get this sorted fairly easily lol i if i can just get android auto working properly. (as it would on a cell phone ) ill be a happy camper.
[Samsung Galaxy Tab S5e Questions & Answers] josh4trunks:
I actually just bought another Verizon Galaxy Tab S5e yesterday, lol. And was able to get it to LOS in less than 2-hours this time, and didn't even need Windows except to download the US Cellular files.

Android Auto should work, my Pixel 5 phone is on LOS and Android Auto works good with my 2017 Honda CRV

also so to get lte i reverted back to att firmware. but after finding out that i couldnt get oem unlocking back i tried to install T727R4TYS4DVI2 but it fails every time.. i can load any firmware but this one.. i lied i can not load any firmware that has cdma bands
[Samsung Galaxy Tab S5e Questions & Answers] goldspeckledriver:
Hey, sorry, maybe a dumb question, but I successfully completed everything in this post but I'm confused on where to pick it back up at the LineageOS instructions. I'm not sure whether I need to install vbmeta.img and if I do whether I do it with patched Odin or with Odin_3.13.1.zip per the LOS page.

Edit: for all future readers, if you're also confused, just follow the instructions precisely on the LOS page from the top after you finish the instructions here. Do install vbmeta and do it with the Odin on the LOS page.

Besides that, I also had trouble with booting into recovery. The protip is, after pressing the volume down + power buttons for 8~10 seconds and your screen going black, do volume up + power even if the samsung galaxy s5e screen pops up. The instructions are unclear so I thought the screen had to be black for it to be "off" to do the volume up + power, but no, doing it during the samsung galaxy s5e screen worked fine to open recovery. I'm now a very happy tablet owner. I haven't checked for whether the SIM works bc I'm not interested in using it anyway.

Those who failed booting to recovery using LineageOS recovery try this:​

These are just the basic steps you may need to read more on how to use TWRP but this will get you started. I was able to get my tablet working with the steps below. I followed @lawofone steps for unlocking the bootloader exactly.

After Unlocking the boot loader install Lineage like this.

1. Flashing the VBMeta Image:​

Download the vbmeta.img file as per the instructions given by LineageOS team (use their file).

Use Odin to flash this vbmeta.img file to your device. Use Odin lineageos supplied.

2. Installing TWRP Recovery:​

Download the TWRP recovery image (twrp-3.6.0_9-0-gts4lv.img.tar)

Use Odin to flash the TWRP recovery image.

Boot into TWRP recovery by using the key combination specific to your device.

3. Transfer LineageOS ROM to Device:​

Download the LineageOS zip file on your computer.

Transfer the zip file to your device’s internal storage (TWRP folder or any accessible directory).

4. Installing LineageOS using TWRP:​

In TWRP, select "Install" and navigate to the directory where the LineageOS zip file was transferred.

Select the LineageOS zip file and swipe to confirm the installation.

(Optional) If you want to wipe data, you can do it in TWRP before installing the ROM.

After installation, reboot your device.

5. First Boot and Setup:​

Allow the device some time to boot up; the first boot may take longer.

Go through the initial setup process of LineageOS, configuring preferences, and connection

Sounds like from your next post you got the Tablet unlocked but for those others like me that got stuck at this point…

Frija for me is downloading now the SM-T727R4_2_20230822180050_8d1pirui5t_fac.zip

You can still find the SM-T727R4_2_20211029161118_ijtwqlgpl4_fac.zip (The firmware indicated in @lawofone instructions) online, however I’d already flashed the 2023 version above so the 2021 flashing failed via Odin, my guess because the version was older.

But in any case for w/e reason after flashing 8d1pirui5t_fac the tablet indicated it was erasing as expected and showed the US cellular logo however it booted rather quickly and did not prompt for a new google setup and just logged in… User data/ cache wasn’t cleared?

And in this state a slider for OEM unlocking was not available.

Resolving this was simply to do a factory reset and after getting back in there was the OEM unlock slider.

##Hurray my transistors flip floop like I tell them to##

On a side note I noticed in the instruction “but do connect to a Wi-Fi network during setup. This allows the tablet to adjust the date/time automatically”

I only do this sorta thing every 3-4 years so I forget all the minutiae of hoops you have to jump through but is this for like OEM time jail or w/e?

--

I actually ran into this issue one more time with needing a factory reset

After going through the steps to unlock the boot loader I noticed that even with the bootloader unlocked after restarting the OEM unlock slider was again missing, I didn’t think anything of it until I tried flashing vbmeta.img per the LOS instructions and found it (I’m forgetting the exact error now) failed to authenticate.

Again ran a factory reset, and this time through the OEM lock slider re-appeared (switched on but greyed out) after which going back into download mode vbmeta.img flashed successfully.

Rest of it went pretty smoothly, except for some weird ADB issues sideloading LOS (it would just fail at 0%) but that seemed to be due to the usual “how is USB-C so bad” shenanigans, and eventually worked with the right cable (a USB 2.0 to USB C one lol)

For ref this was done on a SM-T727V
[Samsung Galaxy Tab S5e Questions & Answers] Topher227:
Did you ever find a solution to this? I have the same exact issue.
[Samsung Galaxy Tab S5e Questions & Answers] shaglord:
Does this T727V and T727A oem unlock still work in 2024? My fear is that the firmware "bit" as it's called becomes too new and so the firmwares that the tutotial instructs to install, can't be installed as Samsung doesn't support downgrading firmwares to an earlier "bit" number.

The bit is as many know the fifth from last digit in the firmware name. Once it's 2, you can't flash firmwares with a 1 in them.
[Samsung Galaxy Tab S5e Questions & Answers] jerrbe:
I too am having the exact same issue. I have a SM-T727U with the latest official firmware (SWREV 6). I am downloading firmware from https://samfw.com/. There are two versions of SWREV 6 firmware for the SM-T727U and two versions for SM-T727R4. I have tried two different patched Odin versions (3.13.1 and 3.14.1) with identical results. I have not tried loading any older SWREV files because everything I read said it would not work.

I can flash either of the T727U versions and everything works fine (which proves usb cable and drivers and odin are all working), but I don't have the OEM Unlock option.

When I attempt to flash the T727R4 versions (BL, AP, CL, and CSC) I get an error in Odin on system.img.ext4 every time. I tried flashing just the CSC and that flashes correctly, but I get errors on boot (error validating footer) and cannot get past the bootloader download screen. I tried a few other combinations and I can successfully flash BL, CL, and CSC. It is only AP and the system.img.ext4 that seems to be a problem, but I have never successfully booted with anything except the T727U firmware and I don't have the OEM unlock. I either get the footer error or a "hash of data does not match digest" error if I mix and match any files.

I also tried booting into recovery mode (holding Power + Volume Up on boot) and using that to clear the cache and user data and then immediately booting into bootloader and trying to load the T727R4 firmware and it still didn't work so I don't think my issues are related to having user settings in there.

One other interesting note: with BL loaded from T727R4 if I reboot and hold Power + Volume Up + Volume Down and select download mode with Volume Up I see an extra line in the status screen saying "OEM Lock : On (L)" which does not show up with the T727U files loaded. So I think this might have worked as everyone else described if I could have got the system image loaded....

Anyone have any advice? This is starting to feel impossible with a SM-T727U that has been updated to SWREV 6....

At least I have always been able to recover from my soft-brick state using Odin and the latest factory firmware image for SM-T727U...
[Samsung Galaxy Tab S5e Questions & Answers] technical_man_02:
I tried this myself today on my SM-T727V to change to the SM-T727R4, and while process itself works, Frija would not give me any form of firmware. I tried to leave the IMEI/Serial blank, but it would not let me, and if I tried to do the automatic detection, it would just give me the Verizon firmware. I had to surf the web by myself in order to find it, where I found it from here(ver T727R4TYU6DWH2), and the flashing worked. Hopefully this will help out for the future.
[Samsung Galaxy Tab S5e Questions & Answers] technical_man_02:
Sorry for the double post. For this, with my SM-T727V, I was able to follow the directions from lawofone's post and it worked like a charm for me. The only difference between what we did was that he automatically got his USCelluar firmware using Frija, whereas I got mine from searching the web, and archived the exact firmware I used in the above post. Besides the difference in obtaining the proper firmware two years later, the process was identical:

Get the proper firmware that has OEM unlocking (USCellular in this case)

Flash the OEM-unlocking enabled firmware with the specified version of modified Odin (make sure to sign out of your Samsung account before doing so. If you do not have the credentials, such as buying a used one and the seller did not properly reset, you can follow this guide to sign out using ADB)

Unlock the bootloader in developer settings

Follow the LineageOS documentation for flashing onto your device. The site doesn't say anything about the SM-T727R4 (the USCellular) model number, but the flashing still does work, and changes the model number on LineageOS to SM-T725

Hopefully this helps.
