Samsung galaxy tab s5e lte - flash different firmware - Samsung Galaxy Tab S5e Questions & Answers

Hey i have samsung galaxy tab s5e lte (sm-t727v) it is unlocked verizon tab i want to flash samsung stock firmware to remove varizon boatload & pre-installed apps & also some features like call & message continuity are blocked by verizon. So can you please suggest which firmware stall i flash & how. I’ve tried flsahing sm-t727 & sm-t725 via odin but it gives error (secure check fail : Pit)

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?

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!

anyone else have success with this? ive followed everything so far but i'm stuck trying to unlock bootloader. the option is there in developer options i can turn it on or off in there but when i power down and boot into download mode the option to unlock bootloader isnt there and it says OEM Lock On (u1)

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?

ok let me know ill be up a few more hrs

you didnt happen to do anything outlined in this thread did you?
https://forum.xda-developers.com/tab-s5e/how-to/samsung-galaxy-tab-s5e-debloat-root-info-t3935010
i wonder if you disabled a Knox apk at the right time to make KG status go away

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.

[Q] G930V to G930U Conversion (Explain please)

Hello, All!
I have a G930V (Verizon S7) Non-EDGE, and I wan't to convert it to a G930U Unbranded (Or at least bloat free).
## BY THE WAY ##
Yes, I have seen other threads on this topic. Doesn't answer my confusions though.
Threads by:
tvm2487 (G930U Firmware)
James.Markham0757 (Can someone send me in the right direction...)
DeathAngel66669 (Using SamFirm to download SM-G930U-G930UUEU2APG9...)
## BY THE WAY ##
So anyways here are my questions.
##
1. Looking through Sammobile or Updato I see that a the newest version is
(G930UUEU2APEH) on (XAA), Would that work for the VZW Variant if not, What can i use?
2. Regarding my phone's below details would i be able to convert it to any of the 'U' Firmwares?
3. I don't wan't to trip any security features or mess with KNOX, really don't want to root.
Really just wan't to keep my warranty. Granted I will probably lose that by not using VZW firmware.
4. I thought flashing firmwares not similar to your phone will brick it permenantly. Why does the 'U' firmware run on the 'V'?
5. If i can flash the firmware (Odin?), What should i tick in the boxes for it to flash perfectly fine without errors?
Given this would be my first Samsung Tweaking.
6. Besides the Verizon bloat, What other cons are in the 'U' firmware that I should know about before doing the procedure?
7. Chances of bricking the phone? Would it be reversible?
##
My current S7 VZW Details:
Model: SM-G930V
Ver: 6.0.1
Patch Level: October, 1, 2016
Baseband Ver: G930VVRU4API3
I appreciate the help and your time. Thanks !
1. Looking through Sammobile or Updato I see that a the newest version is
(G930UUEU2APEH) on (XAA), Would that work for the VZW Variant if not, What can i use?
I don’t think it would flash as it is bootloader 2(5th character from right) latest firmware is 4!
2. Regarding my phone's below details would i be able to convert it to any of the 'U' Firmwares?
From what I understand all the USA variants of the Galaxy S7's are the same hardware
3. I don't wan't to trip any security features or mess with KNOX, really don't want to root.
Really just wan't to keep my warranty. Granted I will probably lose that by not using VZW firmware.
I have an AT&T branded S7 SM-G930A and have flashed the U firmware and used it for a while. I have now switched carriers to T-Mobile used the U firmware without issues and now flashed the T-Mobile firmware and it works fine. KNOW IS NOT TRIPPED.
4. I thought flashing firmwares not similar to your phone will brick it permenantly. Why does the 'U' firmware run on the 'V'?
Not sure, Odin may just fail to complete install?
5. If i can flash the firmware (Odin?), What should i tick in the boxes for it to flash perfectly fine without errors?
Given this would be my first Samsung Tweaking.
I never had luck flashing the HOME-CSC file, had to use straight CSC.
6. Besides the Verizon bloat, What other cons are in the 'U' firmware that I should know about before doing the procedure?
One thing I did notice is the visual voicemail app tends to work better when using the specific carrier firmware(both AT&T & T-Mobile).
I'm using T-Mobile and I don't see a need to go back to U at this time as their is not much bloat on the T-Mobile firmware.
7. Chances of bricking the phone? Would it be reversible?
##
I just installed T-Mobile Nougat on my phone and got the error on phone and it was stuck on “You will need to use Smart Switch Recovery” to fix phone! SCARY!!! I managed to finally get firmware installed and running!
Understood.
When I get home today I'll try to install a newer version from SamMobile.
Updato has older versions. Sammobile has the latest which is.
G930U with code (VZW) on
G930UOYM4APL2
(https://www.sammobile.com/firmwares/download/118975/G930UUEU4APL2_G930UOYM4APL2_VZW/)
Would this be compatible?
G930UUEU4APL2 is the latest U-firmware. Everything flashes correctly, it won't trip KNOX, and it is super easy to go back to G930V firmware if you decide you want to send it back for warranty. You can't brick the phone by flashing signed files with Odin. The bootloader won't allow Odin to flash anything that could brick it.
I had already started replying before you posted above me. I'd recommend using my link to the firmware, as Sammobile downloads take FOREVER.
I see, I'm glad.
So, What would i need to make sure to do and not do in Odin 3.11.1?
AP/BL/CP/CSC from your zip? Just flash everything or only certain things?
Re-partition tick box? yes or no?
Flash all four of those files and DON'T CHANGE ANY Odin settings.
Okay. I just flashed it and now my phone repeatedly keeps booting into recovery.
The recovery logs and the red text at the bottom says:
dm-verity verification failed
Need to check DRK first...
Any ideas?
##PREVIOUS##
I think it might have to be because I used HOME_CSC rather than CSC.
What's the difference between both? Can i revert later?
##PREVIOUS##
@CVertigo1
I reflashed with the CSC file rather than the HOME_CSC file as according to your instructions in your thread (Latest G930U Firmware) and it worked perfectly fine!
KNOX is still at 0x0 and warranty void is fine.
( https://forum.xda-developers.com/verizon-galaxy-s7/how-to/g930u-firmware-pl2-g930v-success-t3558214 )
No bloat, amazingly fast, and some features i like are present. I'll report back to your thread on the battery life when i get more time with it.
I appreciate your patience.
(Will post screenshots later).
Home_CSC doesn't wipe user data, which causes issues when swapping firmware. That's what caused your bootloop.
Followed this, today, was sick and tired of the damn Verizon bloat slowing the phone down.
The phone runs faster - notably faster.
After installing the SIM, the phone returns, "Your device will restart to configure features supported by the new SIM card."
And then" It's useless. If I hard-power reset it, and take out the SIM, it's viable - it's just useless otherwise.
Phone is a G930V, flashed to G930U.
Any Suggestions? The phone is *NOT* rooted, so I can't easily take out or rename the AutoPreconfig.apk package.. Argh.
Will I get the android nougat update on this ROM?
Just converted G930V to G930U, all 100% working here in the UK. Fully debranded and no verizon warning about sim change. perfect
Mind telling me what thread you used to find the latest firmware? This forum for the phone is so rarely used anymore, it's hard to tell what info to go even go on anymore.
Is PL2 the latest for 930U? I'm VZW but US, not UK

S7 SM-G930P ~ Boot Loader Issues? SW REV CHECK FAIL : [ABOOT]FUSED 5 > BINARY 4

Hi All.
Thank you for any help you might give me in advance with this issue...
Last week, I tried to root the phone with the SM-G930P CF-Autoroot heroqltespr files with Odin found in this forum. I have rooted a few other phones but am no expert. The root after a few attempts failed (verified a few ways), however, some files must have been affected because the phone "identifies" as heroqltespr. Identifies as when I could plug into my PC heroqltespr would be the name. It was not set this way in the obvious name your device areas. I ended up doing a hard reset to clear the phone and other than the ghost naming everything was working fine.
A day or 2 ago Sprint rolled out a new OTA update which the phone installed. Since then the phone was draining battery life. After uninstalling and reinstalling the SD card today, it seems to have tripped a "Security Notice: Unauthorized Actions". That is when the trouble started. The phone started running hot, basically leaking battery power, and was all lagging. I'm assuming the CPU going Ludicrous speed.
Now, I am in a Samsung Splash screen loop, or or a recovery loop. The only thing it does is go into download mode.
I have tried flashing stock firmware, it fails. I've tried flashing with and without the SD or Sim card. Not really sure what I should be doing. The "P" version of my phone seems to be the bastard child of S7s. Any help you guys cold give me would be great. THANK YOU!

No it isn't.
I get this error message on the download screen. SW REV CHECK FAIL : [ABOOT]FUSED 5 > BINARY 4
I fixed it.
5 > BINARY 4 error, has to do with a Version 5 bootloader Sprint came out with in 2018. The fact that this is only affected by the SM-G390P further complicates things for the average user. Users on version 5 bootloader will need to wait until/If a version 5 universal bootloader for the SM-G930U to get unbloated firmware. Information on restoring your S7 SM-G930P to where you left off before you started trying to root your phone can be found below. More info on Sprint F'n us and BL Version 5 can be found here
https://www.arencambre.com/blog/2018/01/01/fused-firmware-version-locks-samsung-s7/comment-page-1/. There was a post on XDA (which I can't find) which gave the idea that Sprint came out with this version 5 bootloader to prevent people from flashing the phones to the U version and going overseas with them.
The stock files for the first version of Sprint Version 5 bootloader firmware dated 1-1-18 can be found here:
https://www.sammobile.com/firmwares/galaxy-s7/SM-G930P/SPR/download/G930PVPS5BRA1/206876/
Unzip. Only have auto reboot and Re-partition checked as options in Odin.
If you dont mind me asking, did you ever find a way to root the G930P with the 5th bootloader updates? Is it even possible at this point in time? Im new when it comes to rooting but with the amount of time Ive spent browsing the web it seems as if there is nothing. Thanks.

I got screwed by this, I accidentally installed the P firmware, and now I cannot load U firmware because of this 5 > 4 error. I went to the blog you posted (arencambre), and I am only able to install the U firmware modem (CP package in Odin), everything else has to be P. And because of the P firmware, I am unable to edit APN settings to enable my native Hotspot. Is there anything I can do, besides wait for U firmware to come out with a Version 5 bootloader?

Actually, I am on Sprint, and your directions were awesome, thank you so much! The only thing I had to do was change the line to:
settings put global tether_dun_apn "APNDUN,n.ispsn,,,,,,http://mms.sprintpcs.com,68.28.31.7,80,310,120,,default,dun,mms,supl"
I'm going to put a link to the thread so others can refer to it. https://forum.xda-developers.com/sprint-s7-edge/how-to/hotspot-bypass-nougat-ok-t3563446
Hi all,
EDIT: I posted this in another thread that was about two years old, where I followed the instructions that caused this: https://forum.xda-developers.com/sp...msung-galaxy-s7-sm-g930p-root-xposed-t3503599
That thread seems dead-ish and if you managed to fix this issue maybe you can help me also. Also what was lvpre's original post before he edited it, and would it apply here?
So the worst has happened - got a new (used) phone from Boost Mobile, tried this guide, and now I can only boot to the "An error has occured while updating the device software. Use the Emergency Recovery function in the Smart Switch PC software." screen. Sometimes it does take me to the original "Download mode" screen.
Now, I should be able to resolve this by flashing the original firmware correct? (As in, the firmware that was installed when it came)? Or does it just need to be firmware from the same date range that has the same bootloader? ODIN will still let me attempt flashing on this screen, but I still get the same error when I try again, which on the Download mode screen showed "SW REV CHECK FAIL : [system]Fused 4 > Binary 1"
Any advice here? My S6 bricked when somehow OEM unlock enabled itself and I can't get around the FRP lock, I will be VERY annoyed if the same thing happens with a NEW phone. If I can't fix this I am never buying Samsung again. Any advice on this is very welcome! I emailed Boost to ask them which firmware is installed (because I'm an idiot and didn't write it down but have never had flashing go this wrong before).
EDIT: Booting to recovery just shows a blue "RECOVERY BOOTING...." for a second in the corner and gives a recovery bootloop, just keeps flashing that.
EDIT: I apparently tried to flash an earlier bootloader/etc through ODIN according to the directions in the post I linked above, and after that I now have this problem. Nobody else in the thread seems to have had this problem, and your post is the closest to anything I can find on this issue. I would be in your eternal debt if you could help me out here.
PLEASE HELP!
EDIT: Theoretically if I can find the original firmware it was on I should be fine, right? Everywhere I read if flashing goes wrong you just flash the original stock on it. I guess worst case scenario I download gigs upon gigs of firmwares for Sprint 930P over the last year and find the one that sticks? Or is the fact my recovery is bootlooping and I can only go into download mode mean I'm bricked?
Hello all,
To follow up on my last post, I found success restoring to stock via this firmware:
G930PVPU4BQH1_G930PSPT4BQH1_SPR_7.0.zip
https://www.androidfilehost.com/?fid=817550096634799807
I left my original post just in case anyone messes this up the way I did. I still need root, but now I know how to reset to stock in the event this happens again.
For the record I bought a used Samsung Galaxy S7 off the Boost website.
IF YOU FOLLOW THIS GUIDE, OR ANY, MAKE SURE TO GO INTO "SETTINGS -> ABOUT PHONE" AND MARK DOWN WHAT FIRMWARE THE PHONE IS CURRENTLY ON AS STOCK. THIS WILL SAVE YOU A HEADACHE TRYING TO FIGURE OUT WHICH FIRMWARE YOU NEED TO DOWNLOAD IF THINGS GO WRONG. DO NOT PAY FOR A FIRMWARE DOWNLOAD OR USE FILESHARE SITES, GO HERE: https://simunlockremote.com/galaxy-s-series-firmware/ AND FIND THE VERSION YOU ARE ON AND IT WILL DIRECT YOU TO A FAST GOOGLE DRIVE LINK.
Thanks to all the hard work all the devs have done that have gotten use. I still need root soooooooooo if anyone knows how to do that let me know!
CHEERS! I am so happy right now

I've got a Galaxy S7 G930P from Sprint. I just switched to T-Mobile a couple months ago and brought my S7 phone with me. I was hoping to flash my rom to either the G930U or the G930T (T-Mobile) version, but both are still bootloader v4 and I hit the same error that everyone else on this thread was hitting.
My main problem is that my S7 phone can't send/receive MMS messages on T-Mobile, even after updating the APN settings, and, even worse for me personally - my phone gets below average reception everywhere I go, presumably because my Sprint G930P rom has locked down some of the bands that T-Mobile uses.
Aside from getting a new phone, do I have any options? Or am I stuck waiting for either a G930T or a G930U update based on bootloader 5?

If your phone is uicc [sim] unlocked from sprint... you can try the following.
1. Odin a dec/Jan firmware...like QJ3. But replace the cp slot with the file from the latest u firmware. This is the modem file.
2. When your phone starts, you will receive a pop up message, just hit cancel.
3. Install a package disabler like sabs, bk, adhell2. Disable securitylogagent . This should remove the annoying message. Sabs takes a little effort to setup, but you may need it for the disabler part. Restart after disabling.
4. Pop in sim. See if the additional bands are unlocked.
If you fail, you can always just odin back to a v5 sprint firmware. But don't try it unless you are stuck on the current firmware and your phone is doing nothing. It won't brick your phone.
While the firmware is not downloadable, modem files can downgrade one major update.
This worked for me, but I only have sprint and haven't tried it elsewhere.

U System firmware on BLv5/6 Phone

1. Thanks to @FP_XDA and GSMZambia for the great directions found here
2. The other stuff and ideas:
The above method does put the U firmware on your phone. I had trouble getting it to connect to the network. I did try different combinations of files in the AP tar; CP; and CSC, but it would either not connect after a factory data reset or loop with the message about my SIM has changed, please restart.
I tried just flashing the following combinations through flashfire, but maybe this is a Sprint SIM issue and it works on other SIM cards; however, I have Sprint.
The U firmware seemed to work fine on the software. Including boot.img in flashfire would take away the eng_boot and root. I just had trouble connecting to the Sprint network.
Do you need to use the v5 combo file and flash a certain CP/CSC before going through the rooting steps? The U firmware CSC file is different in size, so is it a partition (PIT) issue since that will write the cache.img.ext4 file and those vary in size from stock to the U? Is there a certain order to flash in flashfire to get it to work properly?
Anyway, I downloaded several U CSC firmwares (XAA, XAS, SPR (last two are sprint)), but ran into some network issue every time. The operating system seemed stable, but the lack of connection and some random entries under settings make it so close, but yet so far.
I don't mind the Sprint firmware, but can you unlock additional LTE bands if you use the stock sprint firmware on another carrier?
Thanks for any help!
Here is more info about the Settings submenu options:
Here is some more detailed info:
The submenus under settings give me options like K twophoneservice; T roaming; Giga LTE. I think it is CSC related as those carriers are Korean based. I think this may be my issue along with a few others I've seen on reddit. Just wondering why it says that though. I used the G930U version, so not sure why this would appear.
Any help or suggestions?
Thanks
Bootloop
Did you get Oreo working while running on v5? Have followed steps in that video but the phone always gets stuck in a boot loop. I extracted the latest Oreo files from the AP file and every seems to flash right but gets stuck in a boot loop after flashfire reboots. Have tried multiple times with same result. Would rather not upgrade to v6 but was trying to get Oreo working.

I didn't try Oreo, but I didn't have any success getting Nougat to work. It would install and run fine, but I never got it to connect to a network. I tried flashing different imgs and making zip files with additional files to add to the system and same result. I do have additional LTE bands unlocked (12,13,17), but since I still have sprint, I have no way to test it.
I assume that everything would work normal except for VoLTE, but I think you could add that with root.

You have to follow the other guide on here about disabling packages. The only problem: you can't disable packages anymore with the apps from the play store. Samsung stopped that. There are system level applications that are blocking you from connecting to sprints network after flashing eng_boot. My guess is you flashed eng_boot, phone booted, then shutdown and reboot, now no network connection? This happens with the binary 4 version as well. I have been on nougat rooted using U firmware for a good while. I once had to re-install everything and when I went to disable the apps, I couldn't. There is a way to disable them via ADB but its not easy and requires patience. But once those packages are disabled, you will have a perfectly running phone with root.
Here are the packages:

The version used by GSMZambia includes a boot.img file, which removes the eng_boot and root after a factory reset. It sounds like you are actually still b4 for everything. This version is for people on b5/6 and want to install the U firmware. However, you are correct about disabling those packages when rooting on the U firmware. You lose root and eng_boot by flashing the stock boot.img in flashfire. The point is to have the U firmware without root on a b5/6 Sprint S7/Edge.
Maybe it would work if you flash the eng_boot again and disable, but then you are stuck on the eng_boot. Plus it messes with Knox, so I'm not sure if something like SABS or Adhell would even work.

But from what I read in the original post is that BEFORE using flashfire to flash the original boot.img, you are running the eng_boot.img. Is this correct? Btw, flashfire NEEDS root. So you ARE rooted at some point. Therefore, this is why you are being kicked from the network. Thus, disabling those packages will prevent that. But SABS and Adhell no longer work, at least I couldn't get them to. I even paid for the one and used it once. So I'm a bit annoyed with that. But yes, I am still on binary 4 for the BL. It was a requirement when purchasing my phone on Craigslist xD
But, what you are after may not be feasible. This is what you want: 100% U firmware on Sprint Binary > 4 WITHOUT eng_boot?
I always thought the whole point of being on U firmware was for root access though. But anyhow, once you get the U firmware flashed, which BL version is on the device? Is this an exploit that allows for older Binary to be flashed?
I'm intrigued by this method for other reasons. I would really REALLY love for a custom boot.img to be allowed but you can't. If this method is a way to block checking of BL, AP, etc hash checks, then the similar method should be possible for a custom recovery and custom kernel. I miss my kernel.

AdHell 3 still works on Nougat at least. You have to get the newer version because Samsung changed their SDK keys program. I'm not on Oreo, so I'm not sure if it will work. But if you are rooted, you have better options. If you need the new version of AdHell3, I'll post a link.

Basically, when you finish. You'll have the U firmware on the phone, but the BL with still be 5/6. So some things like Knox, System Updates, etc..won't work because of the conflict and will say the phone has been compromised. Also, the phone doesn't bootloop because of those items you need to disable, because you did it before using flashfire.
It works fine after applying the changes after rooting, but it is after the flashfire flash and factory reset that doesn't. Modem you can flash, but the CSC files mostly get erased because parts of them are install to the system with the rom. When you check, the phone has no CSC setup available. Which is why it probably displays Korean carrier settings since that is the default with CSC files present.

The original point of U firmware was to get rid of carrier bloatware and the ability to use most carriers easily with most addons (VoLTE) available.

So in conclusion, you have the U4 firmware running on a Sprint S7 with b5/6 installed without root. Since the phone runs fine with the U firmware, something is causing connection issues to Sprint. I assume he is in Africa (Zambia) and by using a GSM only sim card, it will work.
Unless you want to upgrade to b5/6 and try it, that's probably the only true way to test it. Plus, who wants to be on b4 anyway?

Yeah I am currently rooted with the U firmware BL4. I want to upgrade to Oreo, hoping for performance improvements, better battery, etc. But I guess since the Oreo U firmware is still BL4, I can just downgrade if I can't get root back.

I never mentioned a bootloop? Is this about something else? The point I am trying to address is the loss of Sprint connectivity after flashing eng boot. This is because of the packages that need to be disabled.

So you flash everything, eng boot, and are currently rooted. You then flash the provided file via flash fire, factory reset, and now you no longer are able to connect to Sprint network? When you say "can't connect to Sprint network", are you referring to data or to Sprint network entirely? If you go under your "about phone" section, what does your IMEI and phone number display? Don't actually type it here, but it should be something comprehensible. It shouldn't say "unknown" or a bunch of zeros, etc. [/quote]

I do. A lot of people want to be back to BL4. There is NO difference in the newer bootloaders EXCEPT a special "key" type of thing that prevents downgrading. That is the only thing different. This is why the U firmware is still on BL4 despite having an Oreo update. Sprint changes the BL version just so people like us have extra hurdles to overcome when we want something different. Its very stupid tbh.
But, I would like to help you guys out, however, I AM NOT upgrading to the BL5/6. Noway nohow.
It actually shows a crossed out circle for the signal strength in the status bar. I'm pretty sure I tried it by flashing just the system and system with boot, which removes the root. Even entering apn info had slight issues.
I was hoping someone with more knowledge and a b5\6 phone would give this a whirl. If you get bored, maybe it would be like you flashing the U firmware with b2.
My wife's phone is still b4, so at least one of us didn't get the Sprint screw.

Hmm. That's weird. What does your about phone section say for IMEI and phone number? Everything good? I wonder if something is affecting the PRL. Try updating that via settings menu before you flash the firmware and factory reset. The CSC shouldn't really affect that part. I have changed mine multiple times to just eff around and see what/if anything changed. Its more for the phone to know what menu options are available and such. For instance, call recording shows up when its not a US branded carrier.
Sadly I will never flash the newer BL. But I will definitely keep trying via the thread and if you would like to discord or something similar I would be down. School starts in about 2 weeks so I'm basically free till then
sim boot loop
I have the same issue. I can install the g930u Nougat firmware on my BLv5 Sprint phone (you seem to need BLv6 for Oreo), however, the phone will not connect to the sprint network. I flashed the cache.img file and it does the same thing. It forces you to reboot to finish setup then errors out on the blue sim card screen in recovery. I removed the AutoPreconfig app through adb shell to bypass the forced reboot and tried to just select Sprint as the network under connection settings where you can search for available carriers. That too failed...it just sat there for a while then said that it couldn't connect and shows the emergency calls only as the network up top and low signal bars.

Thanks for posting this!!! I'm glad that I wasn't the only having this issue. I tried it again using a different method and still got the SIM boot loop. This method probably works great if you have anything other than Sprint or Sprint MVNO, but something is conflicting like it does during a typical root of the G930P. Anyway, hopefully, someone else will be able to figure this out.

G981U and G981U1 Firmware Links and Flashing Discussion Here

For those who aren't already aware, G981U is the model number of all of the US carrier versions of the S20. The G981U1 is the model number of the same device, but sold by Samsung SIM unlocked and with no carrier bloatware. Firmware is 100% interchangeable among these models: any U or U1 firmware version can be flashed to any U or U1 device at any time, assuming that you're not trying to downgrade the bootloader. A "U to U" or "U1 to U1" flash does not require a factory reset, but changing from one firmware to the other will require one. Also, U firmware is identical for the 4 base files (AP, BL, CP, CSC) for each individual build, no matter which carrier it comes from. So if you download 2 different carrier versions of the exact same build, the 4 base files will be identical. Where the firmware differs is in the USERDATA file - that's where the carrier bloatware and customizations reside.
Manual Odin flashing is designed for those who:
- want to manually update to a newer version of U firmware on their U device, either because they don't want to wait for their carrier's OTA or because OTAs aren't working on their device, or a different carrier got a new feature/patch before they did
- want to flash U1 firmware to their U device
- want to convert from U1 firmware to carrier U firmware
- want to convert from one carrier's U firmware (with all apps and bloatware) to a different carrier's U firmware (with all apps and bloatware)
For those who aren't already aware, anyone can now download firmware for almost any Samsung device any time that they want, via SamFirm or Frija. There are threads and info about them here on XDA so I won't waste time explaining - do a search if you're not already familiar with these tools. But they only provide whatever the latest/newest/current version is - nothing older. I pay for a subscription to a site that gets the official releases (usually) before they hit SamFirm/Frija, so that's where my files come from. However, I don't have unlimited bandwidth on the site, and it's also quite time consuming to download the files, zip them up, and upload them to AFH. And, I do threads like this for every single Sx and Note x model - so I won't be uploading every single version. The only full builds that I upload are ones where I get access to a new bootloader and/or Android version early, before they hit SamFirm/Frija.
This is not a "beginner's guide to Odin flashing" -type post/thread, so I won't list basic, step-by-step flashing instructions. My threads are geared towards those who already know what they're doing. If you're new to manually flashing Samsung firmware (or haven't done it in a long time), I recommend you consult one of those "beginner's" guides- there are tons of them here on XDA.
Happy flashing!

(Quebec tends to be the fastest download mirror, if it gives you that option)
Notes:
- DON'T QUOTE THE OP WHEN YOU REPLY, kthx
- I have lots of threads just like this one for other Samsung flagships, if it interests you. For those who have already made use of my previous threads for a different device and are upgrading to an S20, welcome back
- My zips are compressed extra small for space and bandwidth savings. The default Windows extractor can't handle it, so you'll need a 3rd party tool like 7zip, WinRAR, etc
- My naming method for folders on AFH is: build - bootloader - Android version
So "SAT - 1 - 9.0" means the full build number ends in SAT, it's bootloader version 1, and it's Android 9.0. When bootloader and Android versions increment, the first build to have those changes will have its folder notated appropriately.
- HOME CSC file keeps data intact; using the other CSC will wipe data. Flashing USERDATA will also wipe data.
- Since AT&T doesn't allow their firmware to be publicly available (for any of their devices), I'll try to always upload at least one USERDATA per bootloader increment for AT&T (and Cricket, if they get this model). I'll also upload any full builds if AT&T is the only carrier to get that specific build, because you won't be able to find the files anywhere else.
- For identifying USERDATAS, and to know what region/CSC to use in SamFirm/Frija:
AIO = Cricket (not available via SamFirm/Frija)
ATT = AT&T (not available via SamFirm/Frija)
BST = Boost Mobile
CCT = Xfinity Mobile (Comcast)
CHA = Spectrum Mobile (Charter)
SPR = Sprint
TMB = T-Mobile
TMK = Metro PCS
USC = US Cellular
VZW = Verizon (available via SamFirm/Frija, but Manual Entry is required - Auto will not work)
XAA = U1 firmware
- the correct procedure for switching from one carrier's firmware to another is:
1. Flash full U1 firmware package including non HOME CSC
2. Upon boot, insert a SIM of the carrier whose firmware you want
3. Watch for the popup that says "reboot to apply new carrier settings" etc, and do it
4. After that restart completes, reboot back to Download mode and flash the full U firmware package, with the USERDATA file of the carrier whose firmware you want
Pre-release notes:
1. I do not have one of these and do not plan to acquire one, so I have no idea if anything can actually be flashed at this moment - I'm just providing the firmware. Like all other models, I'm assuming patched Odin is needed for this, but it wouldn't surprise me if a new version is needed for this specific device. There's only one way to know though, so as soon as someone gets their hands on one and can try this, please let us know.
2. I don't know if using the HOME CSC will actually save data. I don't get access to that file straight from the source - I have to decompile the regular CSC, remove the parts that initiate the factory reset, and then re-compile it. Based on the S10 and Note 10, I've done what I think will avoid a factory reset. But the S20 has some new partitions, so we won't know for sure until someone tests it. So if you're willing to be that guinea pig, you're responsible for taking proper steps to avoid an FRP lock, make sure your data is backed up, etc
So I flashed with Odin with my unlocked from Samsung U1 firmware to the T-Mobile U firmware because I wanted the advanced messaging. Only issue in the beginning was not using the patched Odin, but once I did, no problems.

Since it's been awhile since I've done flashing or Odin, I followed this basic guide:
https://forum.xda-developers.com/s10-plus/how-to/guide-g975f-flashing-megathread-faqs-t3936704
Of note, only needed the files from the TAW folder only, did not need the T-Mobile specific U firmware as resetting the phone with a T-mobile sim automatically loaded it.
My quick rundown:
1)Extract the G981U_TAW firmware file you just downloaded. You should get 5 files:
AP (System & Recovery)
BL (Bootloader)
CP (Modem / Radio)
CSC_OXM (OXM CSC file, will wipe your phone)
HOME_CSC_OXM (OXM CSC file, will NOT wipe your phone)
2.)In Modified Odin I added each file to it's respective slot EXCEPT for HOME_CSC as I wanted to do a clean factory reset
3) Put the S20 in Download/ Odin mode. 2 different ways as outlined here https://www.youtube.com/watch?v=ZPSWEL6-gWg&t=8s
4) Once the phone was detected in the COM port number in Odin, I clicked the start button and waited til Odin said "PASS". One thing I noticed was the phone didn't reboot all the way automatically, it actually went into recovery mode and I ended up having to do a factory reset through there because at first it would bootloop and take me back into recovery mode, but after doing a factory reset in recovery mode it restarted just fine with the T-mobile firmware along with the t-mobile apps and advanced messaging working as it should be.

If you're saying that you want AT&T apps and bloatware and features, then all the files that you need are already linked in the OP
I'm worried that I already know the answer, but i'm asking it anyways. I'm currently on a SM-G981N (South Korean version), which is a Snapdragon865 phone. I'm wondering if I can change my firmware to the SM-G981U version to get rid of the bloatware on my phone. For what I read for other phone's this wouldn't work. Perhaps I should start looking for an unbloated SM-G981N rom? Thanks!

I'm assuming the flash would fail. But there's only one way to know for sure
I'll first try an unbloated korean firmware, until I'll find out if crossflashing between different region phones is safe and working...

I don't understand what you're asking
Tried to flash the unbloated (my assumption at least) of the Korean rom: KOO. Followed the correct steps, flashed without problems but bloatware was not removed, also bootlogo of the original carrier doesn't disappear.
@iBowToAndroid, have you tested this method yourself with the S20 series? Flashing from unlocked to carrier firmware should always work I would say, but the other way around, have you got confirmed results for the S20 series?
SM-G981U Carrier Aggregation for Europe
I have S20 SM-G981U1 that i flashed with SM-G981U with no problems but is there any way to make CA to work in Europe?
Any help will be greatly appreciated because i have way lower mobile data speed in EU with my US unlocked phone...

For U and U1 firmware, yes. You'll have to look elsewhere for discussions on Korean firmware
So you have tested flashing from (US) carrier firmware to unlocked carrier on the S20 succesfully? All bloatware and carrier bootscreens removed?
Any firmware (compatible with U1) that has CSC feature enabled for native call recording?

@iBowToAndroid. Have you got confirmed results that bloatware is indeed removed including boot animations when changing from a US carrier branded phone to the international firmware on the Galaxy S20? I'm starting to wonder if there have been new restrictions in the S20 series that won't allow the CSC to be modified and therefor bloatware/carrier logo's won't be removed.

International firmware can't be flashed to a US model - never have been able to, never will be able to. Just because it's bloatware free doesn't make it "international". But yes, flashing the U1 firmware package removes all of the bloatware - it's been that way ever since the S7

Sorry, typo, should have been "unlocked" firmware.
You still haven't answered my question though Have you got confirmed results? Proof? I see you had good results for the S10 series, but so far I can't seem to find similar results for the S20 series.

Unbrand an LTE Tab A Sprint unlocked sm-t517P

Hello, I am trying to unbrand my LTE Tab A from Sprint SM-T517P by flashing another CSC, or flashing another PIT on a patched version of ODIN with no success.
Can anyone tell me how to do it properly? I have read about Chimera, and Samkey, but they are too expensive, and I worry about bricking my LTE tablet (do not want to root, and there is no root anyway).
Any help?
I made little progress. I think I got the latest correct firmware for it downloaded, but it didn't want to flash with a patched Odin, but it did flash successfully with a non patched version of Odin.
After that, I tried flashing a CSC from another firmware of an LTE that is unbranded (SM-T515), but I always get a SECURE CHECK FAIL PIT error.
Does that mean I need to unlock the bootloader? Is that even possible? I wonder how Chimera, or Samkey is able to change CSC thru just software, but they are too expensive for me
Any help?
I soft bricked the tablet by flashing the AP, CP, and CSC of the latest firmware of International unlocked model SM-T515... I was able to recover by flashing its latest firmware for SM-T517P.
I worry about hard bricking it, but after so many tries with different things, I feel so close
Flashing only the CSC of any other firmware hasn't worked so far, and flashing anything other than Android 10 Q doesn't work either, even after unlocking bootloader.
I have NOT flashed bootloader of another firmware yet, super worried I may hard brick it if I flash another BL even after unlocking its bootloader.
hmmm i dont think there are many modifying the sm-t517p. i also own one of those on t mobile . i wanted to add twrp and root ....i cant seem to find any version made for it...so onto the magisk played with thatfor a couple days and locked it up a few times ...i think for now ill be okay with no modding ..idk why im compelled to screw p a perfectly fine working tab-phone. i did however just see that kali linux can be run on it without messing the os up..maybe ill ry that next... why did you want to modify yours? so you could switch carriers im guessing? luckily for me t-mobile took over sprint........just curious
bootloader unlock...
Unlocking Bootloader​Unlocking the bootloader on modern Samsung devices have some caveats. The newly introduced VaultKeeper service will make the bootloader reject any unofficial partitions in some circumstances.
Allow bootloader unlocking in Developer options → OEM unlocking
Reboot to download mode: power off your device and press the download mode key combo for your device
Long press volume up to unlock the bootloader. This will wipe your data and automatically reboot.
Go through the initial setup. Skip through all the steps since data will be wiped again in later steps. Connect the device to Internet during the setup.
Enable developer options, and confirm that the OEM unlocking option exists and is grayed out. This means the VaultKeeper service has unleashed the bootloader.
Your bootloader now accepts unofficial images in download mode

Hi, I also have a sm-t517p and have searching to find twrp and root. So you had no luck at all? No root even with magisk?
