Brand New SM-T530 problems - Galaxy Tab 4 Q&A, Help & Troubleshooting

Can only flash the 4.4 root, any other causes the boot loop error, also no custom recovery's or ROM's works..
Sure i can work around this and create the system I like, but it seems like entirely to much work to "reinvent the wheel" as this would be!
Easier to figure out where I went wrong to begin with..
Anything other then pure 4.4 stock and the root from here results this message and refuses to boot
kernel is not seandroid enforcing
set warranty bit : kernel
and sometimes
set warranty bit : recovery
First of all I'd address that nowhere do it say that to use the latest root you need to upgrade the stock firmware, and that messed me over, now i cant update to stock lollipop as it says the original is modified, even if i fully restore from Samsung so that ship has sailed!

Whoa whoa calm down there, we'll figure this out together. You're bringing up a lot of issues, all of which can be addressed, if we tackle them one by one methodically Stay tuned for my next post

OK. First off, you need to update to lollipop for custom roms to work. Use my thread here to download an official lollipop firmware; factory reset your tablet then flash it with Odin and you'll be on lollipop. Yay!
This:
Code:
kernel is not seandroid enforcing
set warranty bit : kernel
and sometimes
set warranty bit : recovery
is not an error. I have successfully flashed about a dozen roms on my Tab 4 10.1 and this always comes up on boot. The reason no roms or recoveries will boot for you is because you have not updated to lollipop yet, which is required for roms to boot properly.
So again, you're mentioning several different issues, all of which can be fixed by updating to lollipop, which you CAN do even with your tab all modified and whatnot. See the Root your Tab 4 with TWRP link in my signature to root your Tab 4 once you've installed the stock lollipop firmware. Trust me this is all doable, I and countless others before you have done this before

Ok downloaded the UK version and installed without major issues
It complained that ext4 was faulty on file first time through but not on second try
(Wi-Fi SM-T530 XXU1BOG2 BTU Region (UK))
Booted for first time, reading Android 5.0.2 as version..
Build Number : LRX22G.T530XXU1BOD8
So now to root it (got premium for most root stuff including busybox and SU)

You can root it with twrp. I would recommend using the tar file for 2.8.6.0 and the supersu 2.49 zip. That's how I've done it successfully multiple times. Once you've got that done you can always update twrp and flash a custom rom

TYVM, althou there are still minor things those i can solve on my end, at least I'm up and running with BlissPop 3.6 on my Tab 4 now

[Q] Rooting Android 5.0?

I've been poking around the forums trying to figure out an answer to this, but nothing so far has worked. My question is a simple one:
How do I root a stock ROM of Android 5.0?
First, the tech stuff:
Device: SM-N900A / AT&T
Android: build LRX21V.n900AUCUEOC1
I had Android 4.4.3 (rooted with Towelroot), which I was finally able to force to upgrade to 4.4.4 by using ODIN to flash a firmware update. In the process, root access disappeared, but my overriding concern was to get Android 5. I found a stock ROM of it here, which I downloaded and which did install perfectly.
Now, I've tried a bunch of different things to get it rooted--including trying to flash the pre-rooted Android that Walter.White posted in another thread (my phone kicks back an "invalid signature" error when I try, the install always fails and what I get is a device that's like it's fresh out of the box)--I also tried the CF-Auto-Root route, with ODIN says fails and which causes my phone to freeze. Towelroot doesn't work, and I can't get Safestrap to work either (it complains that there is no root access and there's no Safestrap option in the restart dialogue box).
I know that I'm missing something, and I know that it's probably something absurdly simple. I've got no doubt someone else has cracked this, any chance someone out there could help me figure out what I'm getting wrong?
You must go back to android 4.4.3 and root like you once did, then flash the pre-rooted version android 5.0 and you're all set. Sounds like you have everything you need, just need to do it in the right order.
I rooted my wife's N9008V which was running Android 5.0 with Kingoroot and afterwards removed Kingoroot with Super-Sume. After that I installed SuperSu.
I know that I'm missing something, and I know that it's probably something absurdly simple.
very simple .
Op you are in the wrong forum this is NOT Note 3 AT&T forum .
I rooted my note 3 by flashing TWRP through odin then flashing the SuperSU.Zip package through TWRP
The n900a can't be flashed with twrp if it has a locked bootloader.

N910TUVS2EPG2 - Caution & Info

Be cautious with the latest N910TUVS2EPG2.
You might not be able to downgrade the bootloader once its updated.
If you look back at the history of builds for the N910T you will see the following:
N910TUV U2 EPE3 = 6.0.1
N910TUV U2 DOK2 = 5.1.1
N910TUV U1 COG2 = 5.0.2
Pay attention to the U1 & U2 numbers.
Notice that you can upgrade and downgrade between 6.0.1 and 5.1.1 but cannot downgrade to 5.0.1
Both 6.0.1 and 5.1.1 have U2 in their build. In the past (at least on some devices) once these numbers change is when you cannot downgrade to a different number.
So whats my point? Look at the latest build. N910TUV S2 EPG2.
"S2" This very well could mean you can not downgrade to 5.1.1 and or PE3 6.0.1.
It also could mean that there have been some other bootloader changes.
There have been some reports that some on the latest N910TUVS2EPG2 have had trouble flashing TWRP.
Disclaimer: This info is not to be taken as golden fact. I'm just providing it so people can look out and be aware this has been the case in the past.
Since a lot of this information has not been confirmed and will not be confirmed by Samsung we can only go by past situations.
This has been indeed the case on both the Note 4 and the Galaxy Tab S2
To everyone that has indeed updated to this new Firmware version (N910TUVS2EPG2) please post any experiences from it.
Any problems? Any confirmed known changes. Anything.
Thanks!
I updated, and I was able to install twrp, root, and xposed. However, I have heard reports that twrp doesn't work for some people.
I updated yesterday. Took a couple of tries, but I got it to install twrp & supersu. Currently rooted on epg2
Can anyone point me in the direction of installing xposed on 6.0.1?
N910T here. Updated to EPG2 and I was able flash twrp, supersu v2.76 and custom ROM. I haven't tried rolling back to 5.1.1 bootloader yet.

Any chance one of you could try rolling back to 5.1.1 or even PE3?
Regarding Xposed it should be the same one as PE3.

Also, How is PG2 running for you both? Anything worth mentioning?

IM NOT RESPONSABLE IF A HEART ATTACK OCCUR OR YOUR PHONE BLOW UP WITH ALL THE ROOF :silly:
IF YOU HAVE YOUR PHONE IN MM PG2 STOCK rooted with super SU systemless and last TWRP instaled (like me) YOU CAN DOWNGRADE TO D0K2 LOLLIPOP :
******REMEMBER Disable Reactivation lock (see picture below) and activate USB debuggin, Before DO this procedure!!*******
1-Download the DOK2 BOOTLOADER HERE https://www.androidfilehost.com/?fid=24269982087008410 and the D0K2 modem here: https://www.androidfilehost.com/?fid=24269982087008409 ( i did use 3.0.9 Odin) >>>>>>>>>thanks to @xoxo_xdagirl91 for post the links!
2- Download The 5.1.1 rom here: http://forum.xda-developers.com/note-4-tmobile/development/rom-maximum-ovrdrive-v15-1-1-t3196653 its an awsome rom by @OvrDriVE and so Thanks for that!
3-Put the ovrDrive 5.1.1 rom into the external sd card together with the upgrade. (because need erase all in the internal memory, remember, make a back up of your data in the phone or in the internal memory if you want).
4-now GO to your TWRP and wipe cache-dalvik-system-data-INTERNALmemory x3 ..........DONT TOUCH YOUR EXTERNAL SD, REMEMBER THE OVRDRIVE 5.1.1 ROM IS THERE!
******REMEMBER WHEN YOU ERASE YOUR INTERNAL MEMORY JUST REBOOT AGAIN IN RECOVERY, each time you erase yor internal memory, when reboot in TWRP you see the warning and said that you need to click in "never show this screen during boot again" just click there and swipe to allow Modifications or the stock recovery will rewrite again. TURN OF YOUR PHONE!
5-GO TO DOWNLOAD MODE TO USE Odin and flash the 5.1.1 bootloader FIRST, WHEN FINISH, Flash the modem ..... REMEMBER: put the bootloader in the BL section FIRST AND FLASH & FOLLOWING THE modem in the CP section of odin
6- When finish the step 5, go to your recovery TWRP>install>go to ext sd>flash the ROM first, when finish, wipe dalvik, cache and reboot again in TWRP
7- Just flash the othe part of the rom........the upgrade zip file, when finish just reboot the system aaaaaaaand
WALAAAAAHHHHHH!!!!!!
I DID IT EXACTLY AS DIRECTED AND I HAVE A CLEAN OVRdrive
rooted rom in 5.1.1. Now you can flash via ODIN the original firmware on 5.1.1:good::good:
Just wanted to share my experience for posterity. Here's what I did (and promptly undid). I don't know much about anything, so feel free to laugh and/or point out where I went wrong:
1. Installed the stock N910TUVS2EPG2 from Odin on my 910T.
2. Flashed SuperSU System Mode (which is wrong, I think...should have done systemless, right?)
3. Got the scary yellow "set warranty bit kernel" message and nothing else on the screen.
4. After a couple of attempted reboots, I got the message saying something to the effect of unauthorized software being installed and I'd have to send it in to get it repaired.
5. After a couple of reboots (pulled the battery and tried turning it on again a couple of time), it went through a full boot. After the boot was complete, I got another message within the OS about unauthorized software.
6. Opened SuperSU, unrooted and restored stock recovery.
Everything seems fine now, like nothing ever happened. Calls, data, wifi, and all that are working. I'll wait for the experts to chime in before I attempt this again. I'm just happy it works...at least as far as I can tell.

Those scary red and yellow warnings are standard. Just lets you know the phone has been modified, nothing to worry about. To keep it simple, you can use either systemmode or systemless. And of course you will get a message saying the phone is using an unauthorized software, because you just flashed a custom ROM. Haha. That only pops up when you check for system updates.

Thanks for the response! I gave it another shot this morning.
Used CF Auto Root, installed TWRP, no issues. I was having random restarts on non-stock roms, but none on this one even with rigorous testing.

Glad that everything is running smooth for you! I normally like to run stock, install TWRP, root, and then tweak whatever I don't like. Right now I'm running an S7E Port located HERE. Process requires a little work; 1st) flash the ROM, 2) flash kernel, 3) flash data fix, 4) ??? , 5) profit. :laugh:

That is correct; presently you cannot downgrade from EPG2 to a lower version due to security policy changes. Maybe there will be a workaround soon; however, I have 0 issues on EPG2. :good:

Conflicting reports on here. I haven't tried this myself yet but THIS post states a successful downgrade. YMMV.

Could you list the exact steps. I would like to try that ROM as well, considering we don't have any MM ports for our T-Mo Note 4. How is it working so far?

Sure bud.
1) Download the M6 ROM from Dev-Host or from MediaFire.
Put this file in your external SD card.
2) Download the BeastMode kernel.
Put this file in your external SD card.
3) Download the Data Fix - MM_DataFixs7rebootmenu.zip.
Put this file in your external SD card.
4) Boot into recovery. Make a backup of your current ROM just in case. :fingers-crossed:
5) Go into Advanced Wipe (if you're using TWRP) and wipe dalvik, system, data, cache, internal storage (or whichever options are available in the recovery you are using).
6) Flash M6 Rom from Step 1. Do not restart.
7) Flash kernel from Step 2. Do not restart.
8) Flash data fix from Step 3.
9) Now wipe cache and dalvik cahe. Restart.
Once you restart, it will look like your phone crashed or is stuck in a bootloop, it's not. Let it sit there for about 10-15 minutes and it will boot into the setup screen. Good luck. :good:

[mini-GUIDE] BRICKED / DOWNGRADE / SAME / UPGRADE - also ALTERNATIVE to RSDlite

I am not responsible for your bricked phone or pigeon poo on your toupe. Do at your own risk.
Many thanks to @SupahCookie for idea and motivation!
INTENTIONALLY DOES --NOT-- LOCK BOOTLOADER!!!
Get factory images here:
https://forum.xda-developers.com/mo...ock-images-t3736767/post75236696#post75236696
THIS GUIDE IS FOR FACTORY/STOCK ROMs - NOT YOUR AVERAGE CUSTOM ROM which may not have bootloaders!!! (thanks!!!!! @echo92 )
FIX:
IF YOU ARE ABLE TO GET TO FASTBOOT THIS SHOULD WORK.
IF YOU HAVE 8.x bootloaders AND ARE DOWNGRADING TO 7, use "Alternative to RSDlite" below.
1 boot to win - 7 or 10 works fine.
2 boot phone to fastboot, and connect phone to computer.
3 start RSDlite
pick a ROM. I believe I used a 7.1.1 rom
3Nov9-ADDISON_NPNS26.118-22-2-8_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip
RSDlite installed it and fixed the problem.
- -
I was then able to use RSDlite to install @rafikowy 's signed 8.0 . - going up from 7 to 8.
- -
- -
If you are on 8.x bootloaders and want to go to 7.x bootloaders, use this (RSDlite throws an error and stops):
ALTERNATIVE TO RSDlite:
1 I used 7zip to extract that 7.1.1 zip (or any ROM zip) into a folder x,
2 add all the adb and fastboot junk to folder x,
3 add the attached file (rename it to flash.bat) to folder x.
4 boot phone to fastboot and connect to computer.
5 click on flash.bat - it throws a lot of "slot" errors but works just fine.
6 reboot your phone if it hasn't already and go through the 7.x install stuffs.
7 you will not show an IMEI if you are coming from an 8.x bootloader. However, it IS there.
NOTE: you may need to add a line to the flash.bat if there are more/less sparsechunk's in your FACTORY/STOCK ROM...
THIS IS NOT FOR CUSTOM ROMs!!!!!!!
EDIT: 3-8-19: I just did this myself to go back very briefly to 7.1 - be sure you don't flash TWRP to it if your going to take OTAs - it will brick it. boot to TWRP if you need TWRP briefly: fastboot boot twrpimg.img
----------
If you can boot to fastboot screen, you can do anything.
Never OTA a ROM if you have modified recovery (TWRP, etc) or if magisk is present.
https://forum.xda-developers.com/mo...p-flashing-t3813498/post77011495#post77011495
I changed the attached file to add pause and reboot and exit to make it slightly more automated.
I have successfully used this many times going back and forth. If you can boot to fastboot screen, you can save your phone and flash anything you want.
You may wish to advise users that if they downgrade to Nougat not to use Nougat OTA updates. The reason being that a downgraded stock Oreo device may still have the Oreo bootloader on it. Thus, attempting to use Nougat OTA updates may hard brick their device (as the bootloader is likely corrupted, meaning no fastboot).
Users could either use the Feb 2018 NPN26.118-22-2-17 firmware from your link https://mirrors.lolinet.com/firmware/moto/addison/official/RETAIL/ as that was the last Nougat firmware (and thus no Nougat OTA updates) or avoid using OTA updates whilst downgraded.

Interesting. I used the above GUIDE to go up and down a number of times on my phone (about 20 total) , installing and running on both 7 and 8, and then went down to a Nov 7.1.1 and let it ota all the way up to 8.0 and that is what I am using now. I found that when i used a factory zip, and the above procedure, it corrected the bootloaders to the appropriate version that i was flashing - either RSDlite or the more manual path which ignores the errors worked for me.
Using the above procedure , you get the correct bootloaders, which are in the zip.
Please correct me if i am wrong!

That's intriguing - we saw previously on Z Play that users downgrading their stock firmware (e.g. https://forum.xda-developers.com/moto-z-play/help/hard-brick-moto-z-play-patch-abril-t3782927 )and then using OTA updates hard bricked their device (hence the number of users asking for a blankflash, as fastboot no longer works). I don't know if these users hard bricked by downgrading their firmware too far and then flashed an OTA radically different to their previous firmware, or whether it's a risk that's taken by any downgrading of firmware.
When you used fastboot, did you see any 'security downgrade errors' when you flashed the bootloader, and is your bootloader version now C180, as you've flashed the Oreo OTA?

YES - that's why I wrote these 3 guides - before, it was quite possible to wind up with a bootloader mix - esp depending on the zip you use! - factory/stock only!!!
I added a line to the guide saying that it is only intended to be used for the factory/stock zips as these have (I believe) the bootloaders appropriate to the ROM.
Many thanks for pursuing this! - I wonder if we'll have to exclude certain ROMs that are in the factory lists?????

If you have TWRP (or I assume any custom recovery) present when you try to ota, it can download just fine and then reboot to the update. I had TWRP and wound up in a situation where my phone would only boot to twrp no matter what I flashed or restored. I booted phone to fastboot, RSDlite'ed that 11-09-17 factory zip and all was well. In that particular case I did not fully install 7.x but immediately RSDlite'ed rafikowy's 8.0 signed stock and went on with my testing. Since then I always boot to TWRP rather than intalling it and do my thing. (thanks @jceballos )
When you used fastboot, did you see any 'security downgrade errors' when you flashed the bootloader, and is your bootloader version now C180, as you've flashed the Oreo OTA?

Sorry - since it throws a million errors I never look at it if it works.
The particular build I am on at the moment - is BL: C1.82
This one started from that Nov '17 build and ota'ed all the way to 8.0 Apr.
I root and unroot as needed per rafikowy's method but using a boot to TWRP - never an install TWRP.
I'll put up a new guide ref ota and recovery and brick.

1) If you have TWRP, then using an OTA will fail - as you've not got stock recovery (and likely other modifications, including possibly a system partition set to read-write status). As you noted, having TWRP seems to cause a bootloop when rebooting - I'm not sure if the OTA sets a boot flag to stay in recovery until the update is completed. For the G4/Plus, there's a possible solution by wiping the misc partition but I don't know if there's a similar partition for Z Play devices: https://forum.xda-developers.com/moto-g4/help/troubleshooting-twrp-boot-loop-ota-t3714325
The only other solution I've seen is a clean flash of the stock ROM to get your device booting properly.
Booting to TWRP rather than flashing would mean your stock recovery is still present on your device. The only downside is if you need to make modifications, you'd need your computer to boot to TWRP.
2)BL C1.82 seems to be the bootloader provided by the Oreo April 2018 security patch update, so your device looks to be on the right bootloader. It's still curious that the Nov 2017 firmware worked whereas countless other 'factory' stock ROMs caused hard bricks when downgraded to and then OTA updates were installed.
As you mentioned, custom ROMs don't have bootloaders and thus don't care about your bootloader version usually (though I've seen some ROMs require a certain bootloader). However, stock ROMs and stock OTA updates do have bootloaders, which is why downgrading can be risky.

Downgrading is a piece of cake if you don't use RSDlite - it throws an error and stops. Using the bat file it can happily throw all the errors it wants and all I care is at the end I have what I want.
It does indeed change the entire environment when you bat file the zip contents. You can bat file to get from 8 to 7 and then use RSDlite to flash a different 7 OR 8 zip file. There is no resulting difference in whether you RSDlite it or bat file it - the bat file simply comes from the .xml file that is within the zip. There is very little or no difference between that among addison factory/stock zips. Other zips are different (custom ROMs.)
Grab any factory/stock zip for addison and expand it and you will see modems, bootloaders, indeed absolutely everything you would find on that phone if you went to a store and bought it. SupahCookie simply added a couple lock command lines because it was intended for folks who somehow thought that if phone was locked they could take it back to the store and get their money back. Or some such. I found that ATT folk didn't care if you were on CM or whatever if you just needed to swap SIMs or whatever.
I DON'T want to lock the phone as it prevents me from modifying forever. Oh yeah that reminds me I was going to post the obligatory guide (again) about how to flash a white boot logo so you don't get that message - it's still there LOL but since the font is in white, you can't see it.
I have a Moto Z2 Play and used this to get out of a rather sticky situation.. My IEMI shows 0 now and I'm curious if there's a way to fix this? Also, You say you've done OTA updates? My phone is telling my I have some, is it safe to try?

Thanks for feedback and great on success.
IMEI will show zero if using oreo, It will show again if using N. Remember that if you go from O to N you need to use the "Alternative to RSD" as RSD will simply throw an error and stop.
If you have TWRP and/or Magisk you must get rid of them before ota - if twrp present you will soft brick and have to do alternative again - flash a stock recovery. Simply uninstalling/flash magisk will probably not be enough - it will likely d/l but error part way through update. If you are sitting on rafikowy's stock oreo, and haven't modified it, you should be fine. I know Apr and June are out there. I flashed his stock 8.0 and took June fine. Z2 should be no different though of course I can't guarantee it
If you have success, let us know what you have done so others looking in will know. Thanks!

I actually flashed to this: ALBUS_C_7.1.1_NPS26.118-24_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip Which is a 7.1.1 variant and it is showing 0 when I check settings and when I dial *#06#. However upon connecting to the computer and running mfastboot getvar imei it returned a value. I only did the steps above which would mean I don't have TWRP or Magisk (when I fastboot and click recovery I get "no command")

What rom was on phone when you got it and what have you done to it? Has it ever run 8.x?
original country of phone?
The bat file will always throw a lot of slot errors.

It had 7.1.1 stock. I rooted it, and then flashed Resurrection Remix (which was yes 8.1 I believe) and the upgraded bootloader. I then found out my service wouldn't work with that.. so I attempted to flash back to stock which gave me a flurry of issues.. eventually getting to nothing but fastboot working. Flashed back to working with your guide to 7.1.1
If it helps in in fastboot it tells me BL: C0.CD

Custom ROMs won't usually update the bootloader (even if they are newer) as stock ROMs typically only have the bootloader firmware.
You could look into flashing the stock Oreo albus 8.0 ROM https://forum.xda-developers.com/z2-play/how-to/fastboot-rom-oreo-retail-via-fastboot-t3786153 or the 8.0 June 2018 firmware https://forum.xda-developers.com/z2-play/how-to/fastboot-rom-albusretail8-0-0opss27-76-t3822195 but please check that firmware has been released for your device variant.
I don't know if updating your baseband to stock Oreo formally may fix your IMEI issue.

"BL: C0.CD" even right after flashing that albus 7.1.1 using "alternative" above?
What happens if you flash one of the oreo roms from the links I gave you above?
Yeah, RR wouldn't change bootloaders... so you upgraded bootloaders independendently?- that could easily lead to a soft brick... -
I read RR on Z2 and it says nothing about bootloaders even though it says 8.1 based, so i wonder if it needs 7.x bootloaders? I did not read entire thread...
In a reverse, I would wonder if you put an 8 on there if you wouldn't see your IMEI. (On the Z if you flash 8 You won't see the IMEI until you return to 7.)(wondering if z2 is reversed)

Yes, right after flashing that is the BL that fastboot is showing me. I don't recall updating the bootloader so to speak, however RR did require an updated variant of twrp which I flashed 3.2.2 I believe to get (unsure if that would have changed the bootloader or not). I also tried flashing a stock Oreo (which you've stated stock Roms usually only have the bootloaders so maybe somewhere during this process I updated it?). I wish I had all the notes for what I did to give more precise information, but I'm in a position where I really need my phone so I kinda just panicked and started flashing things when my service wouldn't work.
I'm highly considering trying to run an OTA (though very afraid of bricking). - On a side note though, it wouldn't even tell me I had OTA's until I did the steps in the original post here (doing the different 7.1.1. and 8.0 flashes, it wouldn't ever tell me I had updates, and now it does).
*** Edit ***
Looks like I'm able to enter stock recovery, which makes me believe everything is stock at the moment.

If you flashed a stock O that would have changed bl to O, but doing the above with the stock 7.1.1 would have changed them back to N. No matter (other than academic) that you don't remember the path - flashing a stock anything reverts it to that point in time. However, IMEI may have been moved - don't know. It will likely show on EITHER 7.x or 8.x stock - just don't know which.
If you flash a stock 8.x from those links I gave you above, it should offer you ota, ASSUMING there are any at this point in time(Z has 2). Adding Magisk at any point seems to hose you for receiving any more ota's - don't understand why, even with magisk uninstall, so that would mean going back to the latest stock and losing what you have (which is why I try to take a TBPro and copy that backup to PC (because re-flashing 8.x stock will likely reset internal storage.).
yes, if you enter stock recovery, you are likely at stock, though you could reflash the latest 7 or 8 stock to be sure, depending on which you want to use as base. Since 8 is having security fixes released, I choose 8 and will likely have no more interest (no time!) in 7.
So, ran the OTA and it was fine running the update and staying on N. I also downloaded the OTA for Oreo, when trying to update the recovery error'd out. It looked like the error said "Error in modem unexpected results" or something similar.

did it offer to let you d/l it again? you could try that.
However, there exist O stock zips in those links I gave you so you could just flash the latest...

Oreo 8.1 Update T585XXU4CRJ8 problems

Hello all
I installed the latest T585XXU4CRJ8 Oreo 8.1 update over Nougat 7 on the SM-T585. (BTU / UK)
Everything went well using Odin and the Oreo stock rom from the Updato website.
Cleared the cache and factory reset from recovery mode as normal practice. Booted up ok.
The problem is the device doesn't recognise the network sim card anymore (worked perfectly on Marshmallow & Nougat).
I've tried factory reset a few times, no difference.
Removed and reinserted the sim, even tried another sim.
Having checked 'about tablet > software details' , carrier is unknown and the IMEI has dissapeared !
I've tried to reinstall Nougat 7 and Marshmallow 6 back on the SM-T585 and Odin fails every time.
Tried 2 computers and 3 different usb cables.
Even trying to reinstall Oreo 8.1 again Odin fails!
Theres no frp lock activated, and the oem unlock tab is checked, usb debugging enabled too.
I've read somewhere Samsung have done something to Oreos BootLoader file to stop people downgrading back to earlier software.
I know its early days, but if anyone can offer any solutions, it'd be appreciated.:good:
How to change the BL file version, so i can reinstall earlier stock roms back?
The Oreo update seems more hassle than its worth and I didnt expect the sim card to be unrecognised once updated, let alone being faced with the puzzle of how to downgrade the software.
Thanks for reading. :good:
I think the problem was I used all four files (AP, BL,CP & CSC) from the Netherlands rom and that's whats screwed the device up!
As in no SIM card acknowledgement. I ran the IMEI number off the rear casing through a blacklist checking site and it came back clean.
After many attempts trying every Odin program variant possible and even tried mixing and matching files from different stock roms ( MM 6.0.1 , N7 and Oreo 8.1). To try and get the network carrier file installed, Odin refused to install anything.

https://download.chainfire.eu/1069/CF-Root/CF-Auto-Root/CF-Auto-Root-gtaxllte-gtaxlltexx-smt585.zip
https://twrp.me/samsung/samsunggalaxytaba101wifi2016.html
Tried the above routes to root to no avail, but Magisk worked by patching the boot.img file (which worked ok). Then tried Odin to install TWRP recovery, again from the site above, nothing but blue and fuzzy lines on the boot screen. The device wouldn't boot into the OS, had to go straight to download mode. Prior to that, I even installed the TWRP manager apk and connected to wifi to flash the TWRP.img from inside the OS environment and the same happened again with all variants of TWRP! Wouldn't boot, properly, no screen visuals, but lines......
Surely someone else on here has the same device (BTU UK) SM T585 that has a working TWRP recovery?
After many hours, I couldn't get Odin to play ball , so the only option left was to try the route of root, twrp recovery then installing a custom rom from twrp.
(https://forum.xda-developers.com/ga...-ultra-lean-rom-galaxy-tab-10-1-2016-t3467942)
But it's a no go as TWRP wouldn't install properly, I'm totally miffed by the damage the software has done.
Surely just reflashing the CP file should have reinstated the network facility, but it hasn't.
The last resort is for me to wait until Samsung actually release the UK version of Oreo 8.1 and see if I can get the sim card working again.
Moral of the story is wait until a UK version of the update is released, and even then you have to question is it worth it, if Samsung are making bootloader files so no downgrades are possible, nor allowing any modifications.
Hopefully this info may help others out who are thinking of upgrading or having similar issues.
Cheers for reading

I had the same problem, went from Lineage 14.1 to Oreo stock rom (the flashable one you can find on this site, i flashed also the Bootloader/modem file in the thread). No imei, no baseband. Returned back to lineage and got back imei and baseband, but after my screen was going to sleep (after the regular 1 min) I had only black screen and vertical red lines. I flashed then Resurrection Remix 6.2, Lineage 15, Lineage 16, always the same problem. Then I used Odin and the original firmware of Nougat from SamMobile, at the first attempt i flashed only the AP file. I turned to have the same problem, but this time the lines were white. I flashed all the 4 files again with Odin, problem solved and back to Lineage 14.1 (the only custom rom were everything works)

What version of TWRP have you installed for the T585 and from what site?
Also what root method did you use?
I have tried all available and all seem corrupt i.e don't install properly, no proper boot up with onscreen options. Just fuzzy lines.
Again root i've tried many, but don't work with this Oreo 8.1., even Magisk is problematic.
I think its pretty sad of Samsung sending out poor quality updates for us to use. Their heading the same way as Apple and the way they control customers.
If I could go back to a custom MM or Nougat, I would. But TWRP / ROOT are an issue. i.e no TWRP no custom rom!
If anyones thinking of updating and reading this topic, stay clear of the Oreo 8.1 update for the SM T585. Once installed theres no turning back.....so it seems
Thanks for replying.

just flash the nougat firmware from SamMobile. You have to flash all the 4 files in the zip you are going to download. AP, CSC, etc. Once you have your tablet completely stock you can install again TWRP and flash whatever CUSTOM rom you want.
I easily rooted the phone with odin flashing only the TWRP in AP box (twrp taken from this post https://forum.xda-developers.com/showpost.php?p=78145080&postcount=160) avoid the auto-reboot. You have to put the tab in DL mode, connect it to pc, start odin flash the twrp in AP file e unselect Auto-reboot. As soon as the process is done you have to log in recovery mode at the first boot with home + power + vol up and flash dm-verity. I rooted with Magisk without any problem just flashing the v17.3. Now i' m back to nougat (from Oreo) and i can install whatever custom rom i want. But honestly the only one fully working is Lineage 14.1. Resurrection remix 6.2 has problem with camera and gps don't lock. Same for Oreo version. Tried Pie, same problem.
Domenico F
Thanks for the info.
I tried to install MM 6.01 & Nougat 7 stock rom and they wouldn't install, no matter what I did. ( see Odin pictures )
The last chance was to try Oreo 8.1 again and I did manage to reflash the 'Netherlands stock Oreo 8.1 rom' (after 10 hours!) using all four files (AP,BL,CP,CSC).
I then reset the device a couple of times via stock recovery. Took the OEM lock off, theres no FRP lock either. Enabled developer mode > debug mode (all the usual setting changes prior to rooting / twrp install).
At this point the imei and sim card network ARE recognised and work on the device as normal.
HOWEVER I found once I rooted by any genuine means > Magisk v16 (patched boot img taken from stock rom) and also the CF gtaxlltex sm t585 auto root method.
And when the device booted back up, the 'imei and sim card' WERE NOT usable, nor recognised, no network...........I also noticed BusyBox wouldn't install at all, message about integrity of root.
Adaway and Lucky Patcher recognised root.
I also then tried installing TWRP 3.0.2.0 -3.2.3.0 from many locations and again, none of them worked at all. Just blue lines, fuzzy screen etc. On some occasions Odin wouldn't even process the files.
I include pictures of the files I used.
Its evident to me that I can use the device normally i.e sim card , make calls, data etc if I don't attempt to install root / twrp recovery.
So no root , no twrp , then no custom rom usable or installable. It sounds like Samsung are out to stop custom software on their products.
If the Netherlands stock rom 'BL' (boot loader) file is encrypted with this new binary v3 or v4 to stop OS modifications. I wouldn't recommend using it when flashing the new Oreo 8.1 rom or future new releases.
The best way is to just use the AP file ONLY and overlap Nougat 7 or MM 6. And because you've kept your original BL from earlier stock roms, it may be possible to downgrade back to MM or Nougat if need be.
Once the latest new Oreo / Pie 'BL files' are used in the Odin flashing process, it causes big problems.
Hopefully, maybe someone smart enough can find away to decipher these new BL files and offer a replacement method. which will allow software downgrades and modifications

The last chance was to try Oreo 8.1 again and I did manage to reflash the 'Netherlands stock Oreo 8.1 rom' (after 10 hours!) using all four files (AP,BL,CP,CSC).
I then reset the device a couple of times via stock recovery. Took the OEM lock off, theres no FRP lock either. Enabled developer mode > debug mode (all the usual setting changes prior to rooting / twrp install).
At this point the imei and sim card network ARE recognised and work on the device as normal.
HOWEVER I found once I rooted by any genuine means > Magisk v16 (patched boot img taken from stock rom) and also the CF gtaxlltex sm t585 auto root method.
And when the device booted back up, the 'imei and sim card' WERE NOT usable, nor recognised, no network...........I also noticed BusyBox wouldn't install at all, message about integrity of root.
Adaway and Lucky Patcher recognised root.
I also then tried installing TWRP 3.0.2.0 -3.2.3.0 from many locations and again, none of them worked at all. Just blue lines, fuzzy screen etc. On some occasions Odin wouldn't even process the files.
I include pictures of the files I used.
Its evident to me that I can use the device normally i.e sim card , make calls, data etc if I don't attempt to install root / twrp recovery.
So no root , no twrp , then no custom rom usable or installable. It sounds like Samsung are out to stop custom software on their products.
If the Netherlands stock rom 'BL' (boot loader) file is encrypted with this new binary v3 or v4 to stop OS modifications. I wouldn't recommend using it when flashing the new Oreo 8.1 rom or future new releases.
The best way is to just use the AP file ONLY and overlap Nougat 7 or MM 6. And because you've kept your original BL from earlier stock roms, it may be possible to downgrade back to MM or Nougat if need be.
Once the latest new Oreo / Pie 'BL files' are used in the Odin flashing process, it causes big problems.
Hopefully, maybe someone smart enough can find away to decipher these new BL files and offer a replacement method. which will allow software downgrades and modifications

Honestly i think this run for Oreo it's not really worth. I said you what I did and now i have no problems. I'm not in hurry to use Oreo (as stock rom). I think Lineage 14.1 is the most stable and fastest rom i tried till now, and most of all everything is working. I think i'll give a try via Odin to the official stock rom when it will be available for download (i live in Germany) but sadly I don't use most of the Samsung bloatware installed by default.
WRP Oreo 8.1 on Galaxy Tab 10.1 (T585)
Then I've tried
twrp_3.2.3-1_sm-t585_29918 which gives only stripes when booting into recovery
Do I have to flash the stock boot/recovery before flashing this one,
or this is broken, as well.
Many thanks for a hint,
Helmut
Hope this helps.
So, as I was trying to search for my Galaxy Tab A6 (SM-T585) for Deodexed Stock ROM, I stumbled upon this thread https://forum.xda-developers.com/galaxy-tab-a/themes/mod-twrp-odin-t3650215 just follow the instructions to fully flash Oreo. By the way when flashing Root, I would recommend Magisk Beta https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
it does not damage the IMEI at all(Thread here, read the comment:https: //forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445) . The TWRP, I think we should leave it be, don't flash an update for the TWRP.
Thanks. Hope this helps.

Neither does a custom recovery, so not sure what your point is?
I mean if your having problems using MAGISK use the beta version

Unable to install custom roms

I have a Tab E 8 (SM-T377P) and I cannot get any version of TWRP new than 2.8.7.0 to flash, Magisk will not flash, and no custom roms will install.
I've tried both lineage 15.1 and 16, both the standard and GO versions.
It's on stock firmware, 5.1
I rooted with cfautoroot with Odin 3.10.7.
Hopefully someone has an idea on what I need to do.
:edit:
I was able to get magisk installed by rerooting with cfautoroot and then doing a full unroot and restoring bootimage with supersu. Still can't install any roms though
So I was able to update to Nougat using the rom posted in this thread. It was the ONLY place I was able to find the stock firmware. I was hoping that installing 7.1.1 would put me on a new bootloader/kernel that might allow me to install an Oreo rom.
Still, the only TWRP that I can get to boot is the one posted in this thread, which is 2.8.7. The dev posted links to 3.0.2-1 that do not work, but I've tried multiple different versions of TWRP, and they all boot loop and I have to reinstall 2.8.7 via Odin.
All roms say that they are intended for SM-T377P and cancel, although my device is exactly that.
So, after doing a total wipe and flash back to stock 7.1.1 using Odin, I was able to boot back into Download mode and install the latest version of the TWRP posted in this thread - https://forum.xda-developers.com/ga...official-lineageos-16-0-galaxy-tab-e-t3847488
Still won't let me install a custom rom though...
Alright got it up and running on Lineage 16.
I bought this off of eBay to use as a dashboard for my smart home. When I opened it and put it into download mode for the first time, I noticed that it said it was running a custom binary even though everything looked bone stock, it wasn't even rooted. I didn't pay it any mind and went about trying to root it and install TWRP as the dew guides stated. Nothing would work, so I decided to upgrade it to stock 7.1 since it was on 5.1. After I did this, I noticed that in download mode it stated that it was on stock binary and I was able to update to the most recent TWRP for this device. Then I was able to install Lineage and all is well now.
This thread doesn't appear to be getting any traction, but I figured I'd update it in case someone searches a similar issue in the future.

Thank you for documenting your progress.
I am in a similar situation.
I am the original owner of my t377p.
I'm going to try your steps to see if it will work for me.
UPDATE:
Flashing back to Stock and starting the process all over again, as you described above--fixed the problem. I am now running LineageOS16.
Thank you!
I'm glad it worked for you!
That's exactly why I updated the thread, I knew I wouldn't be the last one have this odd issue.
Do you have a copy of twrp the servers are down and I've been trying for week to download it
