[Q] TF101 - upgrade or buy a new tablet ?

Hi All, new to this forum... what brought me here is trying to figure out if I can upgrade the TF101 to android higher than 4.0.3 that seems to be the "normal" latest version you can get.
Issues I have are: lockup, freeze, twitter post (crash twitter), screen weird colors (need reboot) etc... Maybe I have some hardware issue... planing to open the case and verify all connectors are ok and well seated.
I just spent 4 hours looking around this forum and saw the KatKiss 4.4.4 thing... I say thing because I have no clue (and did not find how) to install this thing.
So! Is it worth it that I spent hours more on understanding how to upgrade, debug and all... or I just go buy a new tablet?
I saw some post around the twitter issue that did not work either after KatKiss upgrade, so not sure if it's worth it ?
I was looking at the Samsung Pro tablets with 8 cores... seems amazing! But pricy!
Anyhow, recommendations?
If you say... sure try to upgrade to 4.4.4 with KatKiss... ok, I can try that, but from the last 4 hours of reading/looking around, I did not find instructions steps I could understand.
Most of those steps I have not clue what they are!
These builds are designed to be installed from your favorite recovery. MAKE SURE TO INSTALL A COMPATIBLE ANDROID 4.2/4.3 RECOVERY!
TWRP >= 2.3.2.3 is recommended, new TWRP available here
Backup everything !
Go to recovery
Make a full wipe / factory reset (you can skip this step if you're already on KatKiss-4.4, if ever you encounter a problem do the full wipe and try again before reporting )
Format /system (only if Version<026)
Flash the rom
Flash KatKiss gapps
Wipe cache/dalvik
Reboot

Thanks for any feedback

I have the tab pro and i like it a lot.
I also have the tf101 running katkiss.
The katkiss is running smooth for me.
All is well and no issues this far.
So I would say try katkiss.

Hi Simon.
Is your device already rooted?
You need to root your device first.
What android version are you running?

Device not rooted... Android 4.0.3.
I am looking for step-by-step instructions... if they exist?
Never did that type of mod before.
Thanks,
Simon

Easiest way, use Easyflasher (If your TF101 has a serial number B6O or eariler (Some B7O), it is an SBK1, most B7O and all higher are SBK2) choosing the wrong one in Easyflasher will not do any harm, it just won't work
http://forum.xda-developers.com/showthread.php?t=1688012
1: Flash TWRP recovery with Easyflasher
2. Download KatKiss ROM #33 & Latest Gapps and copy to your MicroSD, stick MicroSD Card into TF101
3: Boot to TWRP Recovery by powering off the TF, then pressing and holding Power & Volume Down until the white text appears at the top of the screen, then quickly hit Volume Up once
4: Goto the WIPE menu, and wipe everything apart from External Storage (This will 100% wipe your TF, so if you have anything you want to keep, back it up, you can also make a Nandroid backup inside of TWRP, so make sure your MicroSD Card has enough room if you choose that)
5: Once everything is wiped, goto the INSTALL menu and install KatKiss ROM you copied to the MicroSD Card (Might have to select External from the INSTALL menu to navigate to the MicroSD Card)
6: When the ROM says it is completed the install, go back to the INSTALL menu and install the GAPPS you also copied to the MicroSD Card
7: Once GAPPS have completed installing (Ignore any messages about failing to mount partitions etc) WIPE Cache and Dalvik Cache (Might ask you immediately after flashing Gapps, if not, do it from the WIPE menu
8: Choose REBOOT > SYSTEM or POWER OFF > REBOOT
9: All being well, you are now running the KatKiss ROM

TIPS:
When using Easyflasher, you're gonna need to install the "Universal Naked Drivers" from the Easyflasher thread - use a 32bit Windows 7 for least chance of any problems, 64bit windows requires driver signing, and so do all versions of Windows 8.x, you can use 8.x but you'll need to disable driver signing mode before installing them

Any problems, reply here and I`ll check every now and then

ok here's the detail steps I did...
1) I have a TF101, B60... S/N, thus SBK1 (what ever that means!)
2) Using this thread: http://forum.xda-developers.com/showthread.php?t=1688012

Found those instructions that partially work:
http://forum.xda-developers.com/showthread.php?t=1514942&page=4
Search in the start menu for Device Manager and open it.
Plug in your tablet via USB while in APX mode (hold power button and volume (+) until the screen turns off).
The driver should try to automatically install off the tablet upon plugging it in to your computer.
If it fails to install, you will have an "Unknown Devices" section in Device Manager.
Right click on Unknown Devices and hit update driver.
Then hit manually install driver. Point the file browser to the root folder of the extracted package that you downloaded.
For clarification: You downloaded the zip in the OP called Universal_Naked_Driver_0.72.zip.
When you extract it, you should get something like Universal Naked Driver 0.72 or something like that.
Point that file browser to the newly extracted folder, NOT the subfolders.
If you point it to the amd64 or the i386 subfolders it will not work. Hope this helps you out!
That is partly true... here's what I did:
1. power button + volume up
2. device manager showed "other devices" - APX
3. right-click APX and update driver
4. point to extracted naked driver folder
5. Cannot install - hash not present issue!

Do this detailed how-to exist somewhere?

CRAP!!! The main reason I updated this tablet was in the hopes to fix the twitter issue... that is, when trying to post a new tweet, the app crash and restart...
SAME issue!
Any tips on this one would be wonderful.

It's easy.
First root it. Rooting has a few basic common steps. just get the files right.
Then install the rom in recovery!
Voila!

I am essentially trying to do this although I have a C20 so I use SBK2 in Easy Flash. However, after I do my wipes, then go to flash my rom, I get an error message that it can't open the zip file What is strange is that I have done this before and have had KK installed on my tablet.

Unsure what you are referring to?
1) Rooting the TF101
2) Fixing Twitter issue
As you see in the thread, I have successfully installed 4.4.4 KatKiss.

Great pleased you managed to get it working in the end, you can now update TWRP to either the latest official 2.3.2.3 or the unofficial which has been taken over by another member, that's possibly why you ended up with the DATA failing to wipe
Twitter works ok for me, but there are 2 different types of KatKiss, there is the normal one which has a speed increase, and the NonLinaro version which has much better compatibility with apps
Its possible twitter is not liking the Linaro version (Normal one)
Anyway, you are set to flash whichever ROMs you like now you have TWRP, but Id advise updating to 2.3.2.3 to avoid issues, that's the version Ive been running since it was released
Oh and SBK1 and 2 mean, Secure Boot Key, SBK1 was leaked and therefore very easy to flash recovery and other stuff to that required the key, SBK2 did not leak, so devs had to find workarounds in order to flash recovery

Wow Simon.
Already so much.
By the way you sound like a pro already
Now just follow what *detection* says.
That Rom is fast and smooth.

I now want to update again since I have some issue with wifi disconnecting and would like to have original Twitter app working.
So here's a couple of questions:
1. TWRP... before I used EasyFlasher that have TWRP 2.2.1
- I did not find easy flasher with TWRP 2.3.2.3 what do you recommend to use to update TWRP? Link please.
2. You said Twitter work for you and you installed the NonLinaro... right?
- I would be using this link: http://forum.xda-developers.com/showthread.php?t=2592890
That's good?
Any other tips, new version since you last post?
Thanks,
Simon

Did you reboot fully into KK before trying to get into recovery after flashing 2.3.2.3?
You need flash 2.3.2.3 > reboot fully into KK to complete the install > then reboot into recovery
Also you can try powering off the TF, then hold Vol down and Power until you see the white text at the top of the screen, then release all buttons and quickly tap Vol up to enter recovery

After first attempt, yes I entered KK then did reboot in recovery and did not work.
I have tried many time to do power with vol down and vol up... I see "cold-booting linux"... then KK, not recovery mode

Beanstalk question .

Hi everybody, I'm new here and I hope my question does not sound too stupid . My grandson brought me his Galaxy tab 2 GT-P5113 and it is a rooted device . It has android version 4.2.2 installed and it will not update because the device has been modified appears . He does not have the original data cable just a cable that will charge . Here is the question. Do I need to hook up to a PC to install Beanstalk rom or can it be installed off of the SD card ? Any help and install procedure would be greatly appreciated . Thank you .

As long as it has a custom recovery installed such as TWRP you can download and flash any rom that you like without a pc

Search for twrp recovery and download and install the correct version for your device (if it's not already installed). Then install the rom using twrp (no pc needed for this).

Greetings,
THIS IS A LONG(will take upto 1 hour of your time) BUT EASY PROCESS. SO DON'T WORRY.
After reading your question I understood that you want to install beanstalk ROM on your device.
I suggest you NOT to install beanstalk as it is discontinued and not updated ROM.
To install the ROM you should have a custom recovery.
I will proceed you as following :
1. Installing a custom recovery.
- Download Flashify from play store.
- Download this recovery from here :- https://androidfilehost.com/?fid=962021903579495495
- Open Flashify and open the flash(or install tab), it must be opened by default anyways.
- Select 'Flash Custom Recovery' and navigate to the file downloaded.
- After you click install, you device will reboot.
- Now you have a custom recovery installed.
2. Downloading the ROM and correct gapps
I suggest you to install this ROM(as it is updated and supported at the moment) :-
- Download the ROM. :- https://androidfilehost.com/?fid=746010030569950580
- Open this website :- https://opengapps.org
- Select ARM, then 7.1, then Pico and download the GApps(google apps, play store and all).
3. Flashing
- Power off your device(make sure you have atleast 30% battery).
- Press Volume Up + Power button until your device vibrates.
- If you get some sort of message, just click "Keep read only".
- Click wipe.
- Click advanced.
- Select : Data, Dalvik/ART, System and cache.
- Swipe the slider to right and wait until you see " Done in the dialog box"
- Press the home button
- Click Install
- Locate the ROM first and select it and swipe the slide towards right again.
- Once you see "script succeeded result = 1.000000" press home button.
- Click install again.
- Locate to the GApps.
- Install it just as you did with ROM above.
- After installation click home button.
- Click wipe and select : Cache, Data and Dalvik/ART. DO NOT CLICK SYSTEM.
- Click the home button.
- Click reboot.
- Click system.
- Done!!
IMPORTANT :- The first boot will take around 5-15 minutes, this is normal. After your device boots, please connect it to your charger and keep it aside for 5 minutes and then set it up.
Thank you, if you have any problem or doubt just write me back.

I have downloaded everything you suggested and will try and install everything later . Thank you again for the instructions .

How I installed madOS (Oreo 8.1) on BLU Life One X (2016)

I finally succeeded it, after literally months of trial and error! So, I am writing this post in hope that someone who wants to install Oreo on Life One X in the future would find this post through Google search.
Here are the steps.
0. From this page (https://forum.xda-developers.com/android/development/rom-official-mados-wiko-fever-clones-t3762800), download the TWRP recovery and the madOS Oreo ROM.
1. Download the BLUEFEVER ROM from this page (https://www.npcglib.org/~stathis/blog/2016/04/13/turned-blu-life-one-x-wiko-fever-4g/).
2. Download the SP Flash Tool from the page above or through Google search. The version I used was 5.1812, which seemed to be the latest version.
3. Download the Universal ROM from this page (https://forum.xda-developers.com/android/development/flashable-wiko-fever-stock-marshmallow-t3720484)
4. The critical things is you should not flash the Universal ROM as it is, because that bricked my One X. You need to copy "preloader_l5460.bin" and "secro.img" from BLUEFEVER in step 1 and overwrite them to the Universal ROM.
5. You need to install the Mediatek Driver. I used "MT65XX USB VCOM" driver. I found it using Google search, but forgot where I got it from. But with that name, I think you can find it.
6. Now start the Flash Tool, and and select the download agent in the Flash Tool directory (MTK_AllInOne_DA.bin), and select the scatter file in the Universal rom (MMX BLU), and then select "Format all + Download". Then, this is very important, press the download button BEFORE connecting the phone, otherwise it will not work.
7. Now, turn off the phone (I mean, power off, not just screen off) and then connect it to the PC. If the tool does not recognise the phone, press volume up + down at the same time when you connect it until the device connected sound comes from Windows.
8. Now the tool flashs the rom. Wait. It may take a few minutes.
9. If it is bricked, just leave it for a month until the battery drains and completely turns off, and then try flashing again.
10. Now, boot up the phone, go to Settings -> About and hit the build number several times to enable the developer menu.
11. In the developer menu, enable OEM unlocking.
12. Now, install the Google USB Driver. This can be easily found through a Google search. You need to get the "platform-tools" directory of the Android SDK, which can also be easily found.
13. Now, turn off the phone, and hold volume up + power button. The phone shows tiny menu (really tiny...). The first is recovery, the second is fast boot, and the third is normal. Choose fast boot. Type "fastboot oem unlock". You need to press the volume up button on the phone now.
14. Now the phone is unlocked. Type "fastboot.exe flash recovery twrp_wiko_fever_oreo.img" to flash the recovery.
15. Restart in the recovery using the 13th step.
16. Go to Wipe -> Format data and format the data, otherwise the recovery will not recognise the storage and will not boot.
17. Go to Open Gapps and get ARM64, 8.1, micro. Editions above micro will NOT install with an error message that says insufficient storage.
18. Now connect the phone to the PC. The TWRP recovery automatically mounts the storage to the PC so that you can copy files into it. Copy the mad OS rom ZIP from step 0 and the OpenGapps from step 17.
19. Flash the two using the install menu of TWRP.
20. Done.
I do not use One X as a phone, so I skipped the radio flashing steps. It currently shows the baseband is unknown. If you want to use the phone feature, I think you need to flash the radio img or something using the instructions somewhere in the linked posts.

Hello everyone, lets root your ulefone power 5 and if you want: flash another rom. I'm kinda new here so don't mind if I'm telling things in a stupid way.
Code:
/*
* Your warranty is now void.
*
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.
*/
Ok, first of all, massive shout out to @gamr13 and @Dukino and @CarelMinnaar for providing some of the files.
Original threat: https://forum.xda-developers.com/android/help/ulefone-power-5-twrp-root-t3848501/
Link to the website I copied and translated the guide from: https://www.chinahandys.net/android-9-auf-dem-ulefone-power-5-anleitung/
Code:
If you are using any custom rom on your phone, I strongly
recommend reflashing your whole phone with the original
firmware provided by ulefone. I'll add the link.
I assume you know how to flash, otherwise search on youtube or
request it and I'll add a guide.
Most files you may need and worked in my case:
MediaFire
MediaFire is a simple to use free service that lets you put all your photos, documents, music, and video in a single place so you can access them anywhere and share them everywhere.
www.mediafire.com
More files in the spoiler below.
Let's begin!
First of all, make sure your phone is recognized by your pc and use a good cable. (the original one broke pretty quickly in my case)
Next, go to system and search for 'build number'.
Tap it untill it says: you are now developer.
Go to developer options and enable: OEM unlocking. Then power your phone off.
Next, download the fastboot and adb zip file I provided. If you already use adb and fastboot, download the recovery zip and you know how it works.
Extract the 'android' folder and put it on the root of your system disk (mostly /C).
Next, go to your command prompt and type: cd \android
Now you start your phone in bootloader. Press and hold volume up and power and let your phone cycle untill you enter bootloader.
Select 'fastboot'.
Plug your phone into your pc and type in the command prompt: fastboot devices
Now you should see the serial number of one device (in my case it was something like ABCD1234567890). If not, install some fastboot drivers and use device manager to select the fastboot driver for your phone.
Then, type: fastboot oem-unlock
Select Yes on your phone and let it reboot.
Re-enter fastboot on your phone.
To be sure: fastboot devices
Flash your recovery using: fastboot flash recovery TWRP_3.2.3_Ulefone_Power_5_AND_5S.img
Then, you need (maybe not but just do it) to reboot straight into bootloader. So press volume up and power untill it shows the bootloader, and then select recovery.
Now your phone may be encrypted or something like that. Select 'Wipe' and accept.
Next, put your gsi (A only, arm64), gapps and/or your decrypt file on your sdcard and flash it!
Known bugs:
- VoLTE - I needed to use a simcard from a different provider to get calling working.
- Hotspot
- Seems sticky to 2.4G?
- MTP not working in recovery
- When waking up your device you may encounter some weird behaviour. Just wait a second and it's gone.
Spoiler: The old guide
Files:
https://mega.nz/#!N2hijYAB!0LLshTYgW...SUfOKpV5BELo4A (seems to be down and dated)
or
http://www.mediafire.com/folder/55lxwzgdd938t/ulefone_power_5
or
https://drive.google.com/drive/folders/1totRbNzS1RBeSO66WW2O0hG2kPGbGERl?usp=sharing
So, the method.
1.) In the files above you will find a file ulefone power 5 twrp root. Extract it and find the map called SP_Flash_Tool. Open this and run the flash_tool.exe. Please download the firmware.zip and the flashtool.zip and extract them. Put the decrypt.zip on your sdcard. (in some cases you need also the 'MT65xx_USB_VCOM_DRIVERS.zip' to install properly)
2.) Once opened the flashtool.exe, go into the options menu, click the connection tag and make sure USB is selected. make sure its set to Full speed and auto detect.
3.) Browse through the map sp flashtool and use the MTK_AllInOne_DA.bin file as the DA file (may be selected by default).
4.) Select the scatter file found in the firmware folder with all the .img files. Its called: MT6763_Android_scatter.txt
5.) While unplugged, hold the volume up and power button to load the phone into it's bootloader mode.
(if your phone is bricked in any screen skip this step) Turn your phone totally off.
6.) Set the SP flash tool to download only and press the download button to start the download.
7.) Plug your phone in and as expected, nothing will happen.
8.) Now, hold the volume up and power button continuously. Keep holding it until the SP Flash tool starts start downloading and the bottom bar loads things. Be sure you immediately loose the buttons, otherwise it soft-bricks itself so you have to start the download again.
9.) Be patient and wait until you get the green check mark, then unplug your phone.
10.) Boot directly back into bootloader. (vol. up and power, hold it untill you get the fastboot screen. Sometimes it takes up to 4 reboots), select and boot recovery.
11.) Now it's all for you! Put something on your sdcard and flash it. Mine seems to be broken so I used an usb stick, wich is working fine. MTP is not working in the recovery.
12.) CarelMinnaar published the new decrypt file, wich I thrust more than the previous russian one. Put it on your sdcard, do a full wipe and install. This should ban the forced encryption.
12.)
A.) For root: flash the magisk .zip file from the files above or search on the internet for the right one.
Thanks to @gamr13

B.) 1. For another rom: search overhere for a system.img Download the A only variant. I'll keep you updated below. I am not using this phone frequently anymore, so updates may come later. @gamr13 will keep you updated
2. Wipe cache, dalvik cache, data and System.
3. Select flash .img and flash the .img at your System.
4. Flash magisk or other mods.
5. There may be some bugs. Sms was not working on the phh treble for me. The launcher crashed also.
13.) Boot up
14.) Enjoy! Feel free to ask anything.
Got some pm's asking what to do if stuck on boot/recovery, this video explains the return to stock process. In short: start spflashtool, select the scatter file in the stock firmware, select download only, firmware upgrade or download and format. Plug your cable in. Then click start, and press vol. up and power until you hear the 'new device found' sound on your pc and let it go. Then just reboot.
Feel free to use his files or mine. Doesn't really matter.

Working gsi images
These gsi images are tested on this phone:
Android 8.1
https://forum.xda-developers.com/pr...-development/experimental-phh-treble-t3709659
bugs: sometimes the screen flickers when powering on. (once or twice per month)
Android 9
https://forum.xda-developers.com/pr...0-resurrection-remix-v7-0-arm64-32-b-t3891636
bugs: a bit laggy. It takes up to 30 seconds to wake up from just screen off. Maybe a bug with the sleep state. When you use your phone frequently you don't suffer from this.
Thanks to @gamr13 :
Alright boys, yet another stride made today.
I've done some extensive testing on some Generic System Images for the Ulefone Power 5. This GSI seems to be the most stable I've used so far and best of all, it has root built-in (of course, it's LineageOS).
This is the only one I've gotten to work with ViPER4Android and root. Quick note that this still does have the screen flicker on the lock screen, but it's not as bad in this ROM compared to others I've tried.
Android Q GSIs currently do not work on the Ulefone Power 5, I've tried and fought hard with 'em but nothing. So, Pie it is for now.
Note: Magisk DOES NOT work. Please do not flash it on this ROM or you will break root access and need to reflash the system image.
First things first:
https://sourceforge.net/projects/andyyan-gsi/files/
1) Download the A-ONLY ROM.(avN): https://sourceforge.net/projects/an...309-UNOFFICIAL-treble_arm_avN.img.xz/download
2) Make a backup of your stock ROM as it is, just in case in TWRP.
3) WIPE System, Data, Cache and Dalvic in the Advanced Wipe section of TWRP.
4) Flash the image as a System Image in TWRP.
5) Flash Open Gapps
7) Reboot into ROM
8) Enable Developer Options and enable root for apps and adb
9) Download ViPER4Android 2.5.0.4 (This is critical as the newest release will not work)
10) Install the driver
11) On every reboot you will have to go into V4A and go to Settings > Turn on developer mode > Disable SELinux
12) Enjoy Android Pie with ViPER4Android on your Ulefone Power 5.

Havoc os
[11][OFFICIAL] Havoc-OS 4.1 [ARM64/ARM/A64][A/AB/AB-VNDKLITE][GApps/Vanilla]
Havoc-OS 4.x is based on AOSP, inspired by Google Pixel. Has a refined Material Design 2 UI crafted by @SKULSHADY. Many useful features that will blow your mind. All you can dream of and all you'll ever need. Just flash and enjoy... General...
forum.xda-developers.com
Not the quickest, but looks nice with the pixel inspired interface. No extra bugs found.

Handy thread!
I can’t get Magisk working though on any GSIs. I don’t ever get a prompt to allow root access to an app or even with it set to automatically grant, nothing happens and apps don’t detect it, yet, Magisk is installed and Magisk Modules install and work no problem.
Weird issue.

It works on (i guess) the android 8 gsi. I do not recommend magisk, as it messes with your /vendor partition. That partition can not be factory reset other than re-flashing the whole recovery/system/vendor/radio etc. Magisk is also not optimized for this device. Tweaks like viper4androidfx won't work. I don't use my phone anymore at this moment, so any tips, tricks or new information is always welcome to ensure that everybody can get the same good experience

That reply gave me serious doubt that you know a single thing about what you're doing. If it touches /vendor, you flash stock vendor.img in fastboot mode, ez pz. Not that it matters at all since nothing will get messed up at all. Magisk works perfectly fine on stock ROM. V4A works on stock, but when I use any GSI then no apps that require root work at all.

It is a problem, I know. We can't do anything than reporting these problems to the Magisk team and hope for help. In my case, Magisk worked for root, but not for the modules. I got also knocked out of Snapchat because of Magisk. Just one of those little things that are part of our development hobby

In my case I got root acces working in Magisk. I apologize for that part about the vendor. You are right about that. I am trying my best to share my experience. I am no expert in anything.

Android 10 and TWRP...
Me. I tested 10 different roms of Android 10 and none works correctly .. I always stay on the Android logo that lights up in a loop. if you find information and manipulations or roms that work and are stable, send me the link or download. Thank you. And if you also find a new TWRP custom 3.3.0 or 3.3.1, put the download here. Thanks ?

8 Days later and I can confirm the ROM has been really stable with no issues other than the lock screen flicker which rarely happens, especially compared to other ROMs. Battery life has had a significant increase even when putting the phone under heavy usage (Call of Duty: Mobile and other games). Performance has shown a decent increase compared to the stock ROM. All in all, very impressed with the substantial improvements the GSI has brought over the stock Oreo firmware that came with this phone.

Can not install ANDROID 10 AOSP v201 !
Hello, I tested all versions of Android 10 phhusson and none works ..
phhusson offers to do this manually but I do not understand where to put it and how to run it!
phhusson: "need to manually setprop ro.skia.ignore_swizzle true"
If you have a solution to my problem, tell me here because I'm tired of Android 9 .. I'd like to upgrade to the latest version and not bother with this Android 9 .. Thanks ​

Android 10 GSIs currently do not work with the Ulefone Power 5.

Tried to install the .xz gsi-image in TWRP but that doesn't work. Can anybody tell me how to install this image, because in TWRP you can only choose between .zip and .img install. Thanks in advance!

You have to extract the file and then you will have an .img
Extract it with Winrar or 7ZIP

I will tell you everything, I must first test it personally and after the upload on Mediafire.
In my opinion, I hope that the scienceillements of the TWRP will not be there ​

I have the files but I can not install it because it did not explain very well the steps ..

He told me this and I do not understand much and it is not clear enough... : no encryption mod first before install latest twrp if your phone doesnt boot from old twrp to twrp 3.3.1​

Rooting SM-T860 OneUi-3.1 and installing TWRP (UPDATE: Updating to latest version without losing data)

(EDIT)
OneUI 4.1 has finally arrived, if you haven't got your Tab s6 rooted, you can just follow the instructions below. This new part is for the people who followed the guide to root their Tab s6 and now want to update to the new firmware version without losing their data. This guide is inspired in https://forum.xda-developers.com/t/...te-rooted-device-whilst-keeping-data.4245989/. But for simplicity of search I have decided to place it here
(END OF EDIT)
I ran into some problems and took some time to figure out how to install TWRP and root the tablet. The normal procedure by which you flash TWRP and then flash Magisk doesn't work as the download mode won't accept non-official files.
Then, once I got my tablet rooted by the patching method of Magisk, I installed TWRP with their app and got stuck in the logo due to not formatting the data.
After some research and quite a lot of time, I managed to get around that and be able to do everything.
Here is a step by step detailed guide of how to do so.
ATTENTION: These modifications void your warranty and may brick your device. I am in no way responsible for any damage you may cause. Follow this guide at your own risk
Requirements:
-> Latest version of the firmware of your model (I used this site which had the latest version and decent download speeds https://galaxyfirmware.com/model/SM-T860)
(To find which version to download, go into the Phone app, and type *#1234#)
-> Latest Magisk.apk file (https://github.com/topjohnwu/Magisk/releases)
-> Disbale_Dm-Verity_ForceEncrypt zip file (https://zackptg5.com/android.php#disverfe)
-> Latest TWRP img (https://eu.dl.twrp.me/gts6l (europe) or https://dl.twrp.me/gts6l (americas))
-> Official TWRP tool (Play Store)
-> Samsung drivers (https://developer.samsung.com/android-usb-driver)
-> Latest Version of Odin (https://odindownload.com/SamsungOdin)
-> SD Card or Minimal ADB and Fastboot (https://forum.xda-developers.com/t/tool-minimal-adb-and-fastboot-2-9-18.2317790)
(If SD card)
Copy Magisk, AP file from the firmware zip, Disable_dm zip and TWRP img into the SD card, else, you will have to use adb sideload
0. Create a backup of all your data (we are going to wipe the data of the tablet)
(Tablet)
1. Activate developer settings (go to Settings->About Tablet->Software information, and tap 5 times on build number).
2. Go into developer settings and activate OEM unlocking and USB debugging.
3. Turn off the tablet and turn it back on pressing Power + Vol. Down buttons to enter Device Unlock Mode.
4. Press and hold Vol. Up and in the next menu, press Vol. Up to unlock the bootloader (attention, this will erase all of your data)
5. Run through the setup, but be sure to activate the internet (this will prevent the tablet from relocking).
6. Activate developer settings again, and go into it to check that OEM unlocking is greyed out.
7. Install Magisk
(PC)
8. (No SD) Copy the AP file to the Tablet.
(Tablet)
9. Go into Magisk, press Install->Patch a file->Recovery mode (on)->Select file (The AP file).
10. Copy the patched file back into your computer.
11. Shut down the tablet.
12. Press Vol. Up + Vol. Down and connect the tablet to your computer with a USB to enter download mode.
(PC)
13. Open Odin, it should show that your device is connected.
14. Go to the settings tab and uncheck the Auto-Reboot option.
15. Flash all the files of the latest firmware, using CSC (not HOME_CSC) but substituting the AP file with the patched one. (With the WiFi version, you might not have a CP file, don't worry)
CRITICAL STEP (if not followed correctly, may lead to bootloop)
(Tablet)
16. Once the flashing is complete, press Vol. Down + Power during 7 seconds to restart the tablet. As soon as the screen blacks out, swap to Vol. Up + Power (and keep pressing even though it asks to press power) to enter the recovery.
17. In the recovery, navigate to Wipe data/factory reset with the volume buttons and press power button to select. Confirm and reboot.
18. While rebooting, you need to press Vol. Up + Power during 3 seconds (Until the press power to continue appears). This is due to Magisk being installed in the recovery partition.
19. Run through the setup again, but this time you need to login into your google account to enter the Play Store.
20. You should have the Magisk app installed. Open it and it will configure itself.
21. When it reboots, press again Vol. Up + Power for 3 sec.
22. Download the Official TWRP app.
(PC)
23. (No SD) Copy the latest TWRP image previously downloaded into the tablet.
(Tablet)
24. Go into the TWRP app and give it root permissions.
25. Enter TWRP flash and select the latest TWRP img
26. Go into the reboot menu and select reboot recovery.
27. The phone will reboot into TWRP.
28. Tick don't show this message again and slide to allow modifications.
29. Wipe -> Wipe data, Cache and Dalvik and Format data.
30. Reboot -> Recovery.
31. (SD) Flash Disable_DM-Verity zip, and then flash Magisk zip.
32. (No SD) enter the advanced menu and open adb sideload. Connect to the PC, open Minimal adb and fastboot and adb sideload the zip files.
33. Reboot system
Congrats, you have a rooted Samsung Galaxy tab S6 with TWRP installed!
FAQ:
1) Ok, I f* up, I am now stuck in the Samsung logo, what do I do?
Press Power and Vol. Down for 7 seconds, this will auto reboot your tablet. Then, as soon as the screen goes off, try to press Vol. Down + Vol. Up and connect through USB to the PC. With some luck, you manage to get into download mode. If you don't, repeat.
Flash the files with the Magisk modified AP, reboot into recovery and factory reset (follow the next instructions if you want to install TWRP), or else flash the stock rom.
2) I am seeing some screens with some warning messages, is that Ok?
Yes, it is normal, Samsung does that to scare people off from installing modifications on their devices. Can I take them off? Yes, but it is not a simple process. If you really want to, follow this guide, but adapting to the device (https://forum.xda-developers.com/t/...sage-on-samsung-a30-after-root-device.3954589). Another important thing is, when you want to enter recovery, you need to keep pressing Vol. Up + Power, even when the tablet displays the message that asks to press the power button.
3) Don't know... You ask

Works perfectly, thank you!

I have a question: to decrypt the internal memory which files can I flash?
