When booting back to TWRP for trying a ROM backup, I was FRP blocked (I forgot to remove google account before booting)...

I was unable to boot back to system...

Flashing the ROM all over again...
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ThomasKHL:
FRP Lock on SM-T825C

Hi,

I've had TWRP, TWRP-Backup, Root & Xposed (Module Fonter) successfully run on my device.

But I need to remove my google account before my every reboot because of the FRP Lock issue...

Are there ways to permanently remove this FRP Lock?

Awaiting help!!!

Does the T825C boot with the T825 boot image?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ThomasKHL:
Hi,

Oh, I believe so...

I rooted mine with SR4-SuperSU-v2.82-SR4-20170918204844.zip

Not SuperSU. The T825 boot image from the stock firmware?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ThomasKHL:
Hi,

Sorry, I am a newbie.

My firmware before installing TWRP was the latest official Stock ROM for SM-T825C.

I flashed the following 4 files with Odin:

AP_T825CZHU1AQG1_CL11289290_QB14189443_REV00_user_low_ship_MULTI_CERT_meta.tar.md5

BL_T825CZHU1AQG1_CL11289290_QB14189443_REV00_user_low_ship_MULTI_CERT.tar.md5

CP_T825CZHU1AQG1_CP6896702_CL11289290_QB14189443_REV00_user_low_ship_MULTI_CERT.tar.md5

HOME_CSC_ZZH_T825CZZH1AQG1_CL11289290_QB14189443_REV00_user_low_ship_MULTI_CERT.tar.md5

I guess my boot image should be for T825C...

Where can I find my version of boot image?

---------- Post added at 12:35 PM ---------- Previous post was at 12:32 PM ----------

During the process, I didn't touch anything related to boot image or boot.img so I guess the boot image was from this T825C firmware...

Hi,

I've been trying to update my T-820 rom with the AQI2 firmware, none of them have booted past the Samsung logo.

Is it possible the recovery needs updating for the new firmware?

The earlier versions all worked fine based on the AQF5 firmware
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Thibor69:
Sorry if this is an obvious answer, but I am a little confused at this part of this TWRP / Rooting guide. The part that says " To disable forced encryption

mount internal storage (DATA) and disable dm-verify" My question(s) are:

Do I need to disable forced encryption? and why or why not?

And to do this, I would first flash 'SuperSU' then immediately flash 'no-verity-no-encrypt_ashyx' ?

Reboot

Thanks for any help !
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] vogemic:
1. Yes, otherwise your device won't boot.

2. I have always flashed dm-verify first and then root.

Hi,

What I did was:

1. Boot into TWRP.

2. Swipe to allow modifications.

3. Go to "Wipe", Choose "Format Data", Resize File to "exFat" (as I recall).

4. Flash SR4-SuperSU-v2.82-SR4-20170918204844.zip.

5. Flash no-verity-no-encrypt_ashyx.zip.

6. Flash 26-07-17-xposed-v87-sdk24-Xposed-by-PurifyOS.zip

I had all those zip files stored in my external SD Card.

So, choose "Storage" before flashing them.

You will see whether they're successfully installed or not if data is correctly mounted (they should be after the File Resizing, in my case).

7. Boot back to System & run com.sec.android.app.kwb_1.0.6-20160801_minAPI19(nodpi)_apkmirror.com.apk.

You will have root & xposed then.

Hope this helps.

PS: Don't Reboot Xposed with activated Modules that are not compatible with Nougat or your system.

If you do, you will run into bootloop.

If it happens, there's still way to solve it by going into TWRP & delete the modules.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Thibor69:
Ok first let me thank you for the reply. ( both of you ) ---- I will do it just like you wrote there Thomas. I have not used exposed before, but I know all about it

and I would like to try it. So you think I will be ok if I just follow what you wrote.... I guess my question is, you mention don't reboot Xposed with

activated Modules that are not compatible with NN. How will I know if they are compatible? and are some modules included in that zip or are you talking

about later when I do add modules? ALSO - 7. Boot back to System & run com.sec.android.app.kwb_1.0.6-20160801_minAPI19(nodpi)_apkmirror.com.apk

Were is that file ? Will it be there or I have to find it ??

Thanks again

PS... One more thing, you mention Resize File to "exFat" .... Is there a reason for that ? and are you sure I should do that ? :) I will try....
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ThomasKHL:
Hi,

1. For xposed modules working & not working on NN, you could try the link below. I myself consulted there...

https://xdaforums.com/xposed/unofficial-list-modules-nougat-xposed-t3639615

I love to tweak font. I've found Fonter & iFont working on NN.

2. For Xposed APK, I've attached it herewith.

In my case, I've tried installing it before the zip or after the zip.

Both ways work.

3. For File Resizing, I'm not a tech guy so I don't really know the reasons behind but it's necessary.

It's a workaround to temporarily decrypt & mount data, I guess.

I've used this method lots of time for my other Samsung devices with encrypted data successfully before.

Hope the above helps.

PS:

Don't try Module PerAppFont, my experience tells it no longer works on Lollipop & beyond.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Thibor69:
Thanks again for the info !! Any chance you or anyone has a link for the latest stock USA firmware ?

It is either: SM-T820 ( AQDC I think ?? ) OR T820-AQD6 ??

I would NOT ask because I know its at UpDato ..BUT.. at UpDato is says it will take over 4 HOURS to download.

just buy the sm-t825 int not sm-t825c
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ThomasKHL:
Oh.. No...

I've just bought it...

It's the official one available here in Hong Kong..

I'm happy with it... Everything works fine, I've yet to try the stylus yet though...

I can keep google account off coz most of my time is in mainland China where google is not accessible..

But I'm eager to fix this & hope someone here will find a fix for it in future...

Sorry to bump this but....

Hi,

I've been trying to update my T-820 rom with the AQI2 firmware, none of them have booted past the Samsung logo.

Is it possible the recovery needs updating for the new firmware?

The earlier versions all worked fine based on the AQF5 firmware
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Are you saying you can boot to system, but not to recovery?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
Thanks for answering...

No recovery appears to work to completion , but can't load zip successfully of rom based on the new firmware, it gets to the Samsung logo, which continues in the pulsing as usual, but no further even 30 min wait. So the recovery appears to have worked but not sure if it's possible that it could be the recovery or not.

Is that possibly the result of it needing update to TWRP or some other error with the ROM.

I've tried flashing over the new firmware as well as old with the new bootloader, and variations of wipe no wipe etc.

Couldn't get an odin flash of the new firmware that would leave the user apps intact, although the internal sd storage was still there which seemed odd.

Any thoughts,
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
You're trying to install stock firmware with TWRP?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
Sorry I may not have stated myself clearly.

To answer...

No,

I have re built the ROM published as a Tweaked ROM here, with the new firmware as a base.

I have tried flashing after full wipe, but also after loading the new firmware from odin then flashing both with and without wipe, all with the same result, I then attempted with a new ROM based on the new firmware but with minimal alterations.... Same result.

If the problem exists with my ROM build, I know that is my problem to find, but my question is...

Is it possible that a new build of TWRP may be required for ROMs built based on the new firmware?

Thanks

Sorry for the delay, I think we're in significantly different time zones
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
If it installs without issue, no warnings etc, then I wouldn't think it isn't related to TWRP.

However to verify try installing it with Flashfire.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] rorymc928:
Thanks still early Sunday morning here, I'll have a look a bit later
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] pgratz:
Hi Ashyx,

Just want to throw my voice in with [MENTION=2320544]rorymc928[/MENTION], I also tried this procedure to install TWRP and root with the dm hack on an AQI2 stock base rom. My tablet then would no longer boot into the system (I could boot into TWRP just fine though). Booting the system would bring up the initial Samsung logo then the screen would go black and flash once every few minutes (while getting quite hot). The only way to get back to a working system was to install an AQF5 rom via heimdall.

TBH, I'm not sure if it was TWRP, root or the dm hack that caused the bootloop though. If I have some time I might experiment with it (though an unrooted rom is not very interesting to me).

Paul
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
When you say dm hack, are you referring to the encryption patch?

Be aware that it requires a Formatted DATA partition to use the patch.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] pgratz:
Sorry, I couldn't remember what your patch was called, I was referring to the "no-verity-no-encrypt".

Correct, I did format the DATA partition, tried before and after (I tried a number of orderings and other incantations to see if I could get it to work). Ultimately, I was able to get things up and running using the AQF5 rom that rorymc928 posted. With that the SU patch worked and I was able to get a booting system with root.

Paul
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
It may take anywhere up to ten minutes after formatting then applying the patch for the system to boot while the OS rebuilds the file structure.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] pgratz:
Agreed, I left it for about 1-2 hours. It seemed to get stuck somewhere because every so often the screen would flash from black to reddish and back to black (very, very fast so easy to miss). Other than that it never seemed to come up.

Paul
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] old_man:
Same here with the new German AQI2 firmware

Going back to AQF3 - working fine
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
So then you guys need to be more specific as to what works or fails.

TWRP boots - y/n?

SuperSU roots and boots (which version) - y/n?

Boot patch works and device boots - y/n?

At which stage does the device fail to boot?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] pgratz:
Hi Ashyx,

Sorry that I'm going by memory at this point (I managed to accidentally erase my stock backup so I can't go back and retest it, rookie mistake on my part...). Following your procedure I was able to get TWRP installed via Hiemdall, then I booted into TWRP. From there I flashed SuperSU (the one from the link in your first post) following the instructions there, including formatting the data partition. I then flashed the no-verity-no-encrypt_ashyx (I see now that you only need one or the other so maybe that was a problem?). At that point I tried to reboot into the system. When I rebooted into the system I got the initial boot screen for some seconds then the screen went black and it just sat like that forever (with very quick red flashes every couple mins).

Hope this helps!

Hi ashyx,

- flashing new firmware AQI2 with odin

- rebooting, all working - I tried it with and without google account

- flashing twrp as in OP

- flashing different Supersu 2.82 SR5, aslo tried SR2 and 3, always the same

- flashing no-verity-no-encrypt_ashyx

- rebooting into system - initial Samsung boot screen, then the screen went black, waiting for an hour or so, only black screen, but I can reboot into twrp

- tried this multiple, always the same, ending with a black screen

- went back to AQF3

- flashing twrp, Supersu and boot patch, everything works

hope this helps
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] JWnSC:
Supersu may be the issue then. One phone I had a while back was picky with the supersu version I used. Thanks for posting this. I'll give it a go on my T820 and report back.

So I installed AQI2 USA (XAR) version. Installed twrp everything works. Wiped data and installed Boot patch. It booted up in a few minutes. So it's probably su causing the issues. I'll test a few su versions later to see if I can get one working. Vogemic already confirmed magisk 14.2 is working.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Ch3ck3rM0n:
So I still stay on the previous version and wait untill you/someone found a solution to use SuperSU on AQI2. I need SuperSU more than higher Patchlevel. I still want to use Xposed to get AppOnSD working.

Another thing is the update process himself:

Is it possible to get/do OTA update if I uninstall SuperSU via UPDATE-unSU.zip and flash stock revovery.img? And so I ask "do someone have the stock image for me"?

I would prefer magisk but xposed is still not working on it, isn't it?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] vogemic:
Sorry, don't use xposed myself. You could look in the forum of magisk if the combo works.

Supersu 2.82 works for me on latest update. First installed AQI2 via odin. Let the device fully boot. Booted into download mode, flashed recovery. Immediately booted into recovery. Enabled modifications to system. Wiped data and internal storage. Flashed the dm boot patch. Let it boot all the way. Then rebooted to recovery and flashed SuperSU 2.82. It did boot loop once like it usually does when installing supersu.

Guys is there any way to update t825 with the new firmware without repeating the whole process? I have installed lots of software and I want to avoid it.......

Also, found out the hard way that xposed works fine (kind of ) with supersu but DOES NOT work with magisk. Has anybody managed to install xposed under magisk?

Thanks in advance for any help
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:
Magisk comes with its own systemless xposed.

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] xpil:
That was my question, whether it works or not on t825.

What about the new roms? Do I have to wipe everything and start from scratch, or there is a way to update, keeping installed apps intact?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Thibor69:
I wish that was true ... I have a fast 50MB line that normally downloads everywhere around 10-15MB but

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Ch3ck3rM0n:
does not work with magisk and xposed..

you have to wipe data again..
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ashyx:

Why would you need to wipe data?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Ch3ck3rM0n:
I need to get it mountable?!

It's like you wrote in your introduction.

Okay it works, but do you have the some strange SETTING menu? I have some "tabs" twice and new tabs like "Serviceprovider --> KT-2...", which run in error on using.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] JWnSC:
Yes I believe it's the new settings menu since AQF5. It is wierd..I'm going to see if I can remove some of those settings and duplicates later when I get home. Looks like the T825 settings menu. It's from Samsung laziness I'm guessing.. Some of those settings are useless for us (with the T820 version) as we have no Sim card (T825 has Sim card).

Edit: the csc file didn't flash correctly. Thanks for the heads up hawk:good:
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] DeHAWK:
Sorry, but you're wrong. This happens because of wrong used or missing home csc.

Go to /system and see if the csc folder is actually there.

If no csc has been applied, a build in will appear.

I had exactly the same while I was doing some testing and didn't want to waste time installing my local csc.

DeHAWK
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Ch3ck3rM0n:
Another reason why I hope so much, we will get a LineageOS on that device soon (or for me the SDInternal usage mode on coming releases). I have the T825 (with sim support) but the menu is still useless for me because it is doubled.

But feel free to find a removal for it ;) Good thing is, it seems to be no xposed or root error.

There is no "csc" under /system at me. How to fix?

Flashing HOME_CSC_DBT_T825DBT1AQH4_CL12125141_QB14698938_REV00_user_low_ship_MULTI_CERT.tar.md5 brings no difference
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] JWnSC:
Thanks hawk :) flashed the home csc but I guess it didn't make a difference there was 2 included. I'll try the other one later
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] DeHAWK:
Hey bro

You must untick auto reboot and after a successful flash, go directly to STOCK recovery mode.

DO not flash the pit csc, only HOME CSC.

DEHAWK
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] xpil:
Sorry to bother everybody again.

Could somebody describe how to ubdate t825 rom without loosing installed software and data?

I have a t825 rooted with magisk, with twrp installed, working perefectly right now....

thanks
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Ch3ck3rM0n:
Why to Stock recovery? And what do you mean with successful flash - - > the AP or HOME-CSC?

At the moment we have TWRP..
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] DeHAWK:
Bro, the STOCK recovery is fully capable to flash your HOME CSC files the right way.

Do this: Fire up your Odin. Go to settings and untick the Auto Reboot option. Go back to Log.

Now load the AP Firmware in the AP slot and you HOME CSC in the CSC slot.

When all ready, put your TAB in Odin mode also called download mode.

Connect cable TAB to PC and wait for Odin to recognise it.

Now flash the AP and HOME CSC . Wait until you're sure the flash was successful - Odin will tell you.

Now wait a few seconds more and remove cable from TAB.

NOW - Press and hold HOME button, then press and hold Power and Volume up until you see the blue text telling you that it's entering recovery mode. RELEASE ALL 3 buttons.

Stock recovery will now install all the local CSC files into the /system. After that it will clean up and reboot.

You now have all your CSC files installed.

You can now re-install TWRP and make the flashes you wish.

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] JWnSC:
I see what I did now..I used an old version of Odin that was on my desktop when I originally flashed it. Used the Odin that was in my tab s3 folder this time. Thanks for looking out Hawk :good:
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Ch3ck3rM0n:
Okay, that explains the reboot into recovery/TWRP as I tried it without your introduction.

So last question:

Is it possible to flash only stock recovery over TWRP to do HOME CSC installation and prevent data from wiping OR do I have to install full rom?

Can't find stock recovery install guide or image...
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] DeHAWK:
Hey bro

Do this; in Windows, use 7-zip and unpack the APxxxxx.tar.md5 file. This will give you the stock boot, recovery and system files. Now you use the same 7-zip to create a zip file containing your stock boot and recovery. Name it: T820 or T825 depending on your model and then the firmware version XXU1AQxx. You should end up with a file named something like; T825XXU1AQF3.zip or.7zip... doesn't really mater. Now send me a PM with the zip file attached.

I'll then repack the 2 files for use with Odin and at the same time remove the force encrypt and verify from them.

They will, when flashed, NOT encrypt your /data partition as would happen if you flashed the stock AP file.

I'll then post the links here, WITH instructions, so others with same model and problem can use them.

Regards

DeHAWK
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ianmacd:
What needs to actually be done to remove force encrypt and verify from the files?

I would like to be able to do this myself for the multiple devices I own from which encryption has been removed.

If the technical details are described somewhere, I'd appreciate a pointer.

EDIT:

You replied to me, but then deleted the posting, so I'll have to respond to your comments here.

I use Linux, not Windows, and am comfortable with any level of technical detail. I've been a UNIX user for several decades and was a UNIX sysadmin and systems programmer for a long time before I retired.

If the explanation would take up too much of your time, I do understand, but don't be concerned about my being unable to use the information.

Hey bro

It's not so complicated as it sounds, but will require quite a long explanation. All my system and kernel work I do on a 1TB, 64bit Ubuntu 16.04 system. I don't use any kind of virtual box etc. On my system, this operation only takes a few minutes.

I unack the image files, make the changes and then create Odin flash-able files. This is just a part of my kernel building setup. That's no magic involved.

So you need to be able to work in a linux terminal and use scripting.

If all you want to do is flash stock boot and recovery then you can flash the images directly with TWRP.

To disable encryption and dmverity just flash the patch provided in the OP.
