[GUIDE/TUTORIAL] Asus Transformer Pad TF300T Any version to Android 7.1 Nougat

[GUIDE/TUTORIAL/HOWTO] Asus Transformer Pad TF300T Stock to Android 7.1 Nougat with 2022 Bootloader unlock
This detailed step-by-step guide helps you transform your Asus Transformer Pad TF300T with Android 4.2.1 to a powerful one with Android 7.1 Nougat.
Don't expect Android 8 or newer on this tab, but 7.1 is already perfect ;-)
Netflix and Disney+ work.
This worked for me only with USB 2.
### I'll make a few notes using this style: PLEASE READ THEM.
Make sure you have latest official updates.
Connect tab to Wifi network.
Go to Settings > About > Update.
You may have to restart tab and do this step again to correctly fetch latest official update.
To check your tab is the correct model, go to Settings > About tablet. The details below are listed :
• Android 4.2.1 (Jelly Bean, versions from 4.1 to 4.3.1)
• GPS 7.9.11
• Wi-Fi 7.1.1.50
• BT 10.38
• Camera TF300T-000128
• Kernel 3.1.10*
• Build number
Tap 7 times on this item to unlock the developer options menu.
We need it later
It looks like J0P40D.WW_epad-10.6.1.27.5-20130902
################# TO GO FURTHER, your BOOTLOADER version MUST END IN 27.1 or 27.5 (27.5 in my case).
### If not: reboot tab and check again for system updates
### If it still not 27.1 or 27.5, go straight to the EXTRA part of this tutorial.

Open a Windows command prompt on the /djibe pack folder you unziped earlier:
select folder with left click, right click while holding SHIFT on keyboard > Open command windows here
or while in /djibe folder, type cmd in Windows address bar and confirm with Enter.
### Use fastboot.exe provided in archive. Latest Google binaries won't work.
In Windows Command Prompt (not Windows Powershell !), type:
Code:
fastboot devices
.
If the serial number is written, tab is well connected.
### If not: try this command :
Code:
./fastboot devices
### If still fails: try another USB port
### If still fails: Launch Windows Command prompt in Administrator mode
### If still fails: Check Universal Naked drivers installation
Now type:
Code:
fastboot -i 0x0b05 flash recovery twrp-3.4.0-0-tf300t.img
and wait for the "finished" success message,
### If it fails, try other tricks like above (change USB port, Run Command prompt in Administrator mode, redownload TWRP from official site)
then type:
Code:
fastboot -i 0x0b05 reboot-bootloader
and confirm with Volume+ to load RCK (recovery), it is now TWRP 3.4.
### FROM NOW ON, ONLY USE TWRP RECOVERY TO WIPE DATA OR PARTITIONS, never again bootloader's Wipe data icon !!!
8) SET FILESYSTEM TO F2FS AND NANDROID BACKUP
F2FS is the fastest filesystem for read and write partitions on flash memories. Compared to EXT4, gain is from 15 to 280 %.
No need to format the /System partition because it is Read only and Ext4 is still faster.
On TWRP first launch, check Never show this screen during boot again, then Swipe to Allow Modifications.
Go to Backup, make sure System, Data and Boot are checked.
Now tap on Select Storage button > set it on Micro SDCard,
Swipe to Backup.
Tap on the Home button.
Now go Wipe > Advanced Wipe.
Select Dalvik / ART Cache, System, Cache, Data, Internal Storage and Swipe to Wipe (NOT MICROSD).
Tap on Back button (to Advanced Wipe Menu).
Select Cache partition > Repair or Change File System > Change File System > F2FS and Swipe.
Go Back and back to Advanced Wipe Menu.
Select Data partition > Repair or Change File System > Change File System > F2FS and Swipe.
Tap on Home button.
9) FLASH ANDROID + GOOGLE APPS +/- MAGISK
Still on TWRP Home screen, Install > Storage: Internal Storage and change it to microSD card > OK.
### If it fails, use Kang Recovery (without F2FS partitions): https://androidfilehost.com/?fid=24052804347781183
Select KatKiss-7.1_TF300T*.zip, and Add More Zips,
then open_gapps-arm-7.1-pico*.zip and Swipe to Install.
### If it fails, install zips 1 by 1, make sure microSD is valid and that you downloaded OpenGapps ARM 7.1 PICO version.
OPTIONAL --------------
Go to Reboot > Recovery.
Back to TWRP, go to Install > Magisk.zip and Swipe to install.
Be patient.
Android 7.1 is installed.
When done prompts, tap on Wipe Cache/Dalvik and swype to confirm, wait.
Disconnect tab from PC.
Then Reboot System.
Let the tab start (long time).
10) ANDROID 7.1 Nougat
On Android first launch, immediately manually toggle Wifi ON or you'll run into an app crash (Wifi toggle button is on bottom right of screen).
If your Wi-Fi network is not listed, scroll down to Don't use any network for setup (and refer to chapter 12 to access it again)
Configure Android as you like.
Go to Settings > Performance
Check Set clock values on boot
For Maximum frequency, select 1700 MHz.
I/O Scheduler set zen and Set value on boot
In Settings > Mediascanner filters, uncheck Scan.
In Settings > About tablet, tap 7 times on build number, it unlocks the Options for developers in Settings.
Enter this new menu.
In the Hardware acceleration, make sure Force GPU rendering is NOT checked !!!
11) ROOT WITH MAGISK (OPTIONAL)
Magisk root is started with Android, no need for extra manipulation.
You can manage Superuser permissions and Magisk modules from Magisk Manager app.
12) OTHER APPS
- You can use GPS Status & Toolbox for faster GPS fix.
- Kernel Adiutor for advanced overclock
- KAT App to enhance Audio: https://forum.xda-developers.com/transformer-tf300t/development/app-t2824215
- Any Magisk Module or Xposed Module.
- Your tab doesn't see your local Wifi network? You are probably european and your Wifi is set to channel >= 11.
Go to Settings > Wi-Fi > 3 dots icon > Advanced > Change wifi regulatory domain > EMEA and Rest of World.
Reboot tablet, you now see your Wi-Fi listed.
### If not:
Go to Settings > Security > Switch Unknown sources ON
Download from Play Store Smartpack Kernel Manager or with KatBrowser go to m.apkpure.com
Reboot to TWRP recovery (hold power to shutdown > long press on Reboot)
Go to Mount > Check System partition
Go to Install > flash Magisk*.zip
Reboot > System
With Smartpack Kernel Manager, edit build.prop
Look for ro.wifi.channels and set a value of 14 (ro.wifi.channels = 14)
Reboot tab to list all Wifi networks.
- To uninstall Magisk, rename Magisk-v23.0.apk to uninstall.zip and flash it with TWRP recovery
- Edit build.prop
Reboot to recovery > Mount > select System
adb devices
adb root
adb remount
adb pull /system/build.prop
Edit with Notepad++ and save
adb push build.prop /system/build.prop
adb shell chmod 644 /system/build.prop
That's it.
Enjoy ;-)

EXTRA - UPGRADING BOOTLOADER VERSION OF ASUS TRANSFORMER PAD TF300T
- Either use latest official updates in Settings -> About -> Update (While connected to Internet).
But if you are here, it seems to fail ;-)
- Manually update
In your bootloader version, check for the 2 first letters.
If the letters are corresponding, download the file from the official link.
US : http://dlcdnet.asus.com/pub/ASUS/Ee...7.1996726876.1498828408-1286149849.1498586515

Now, unzip the archive once to obtain it like this : WW_epad-user-10.6.1.27.5.zip (WW or whatever 2 letters you require)
Rename WW_epad-user-10.6.1.27.5.zip to EP201_768_SDUPDATE.zip .
###Beware not to rename it to EP201_768_SDUPDATE.zip.zip !
Copy EP201_768_SDUPDATE.zip to the root of a microSD card formatted in FAT32.
Insert microSD in TF300T shut down.
Start tab in Bootloader Mode (Power + Volume-).
Go to Recovery Mode (RCK)
Flash zip, reboot.
Normally it worked ;-)
Check bootloader version again for xxx.27.5 .
Start this tutorial from start again if bootloader ends in 27.5 .
If not, ask for help in this thread.

You are right! It is very important to convert /Data only to F2FS, never /Cache, never /System.

Nope! Please stay on Kang TWRP as advised by Timduru in order to avoid any known issues caused by TWRP 3.0! Ever follow his install instruction for KatKiss 6.0.1 carefully.

I tried on a win7 machine but I cant install the drivers (INF file you selected doesn't support this method of installation)
Any help greatly appreciated ofc

Simply flash Kang TWRP 2.8.7.2 !!! (https://forum.xda-developers.com/transformer-tf300t/development/recovery-twrp-t3046479). This is the right one for TF300T.

Will I be able to do that without the drivers ? I'm under the impression that fastboot doesn't see my tab so I can't install a recovery.

I can't seem to pass the PC to tablet connection step. What could go wrong?
My PC's OS is Windows 10 Pro, 32bit version. I followed the below guide:
2 - INSTALL WINDOWS DRIVERS FOR ASUS TRANSFORMER PAD TF300T
- Windows 8/10 :
On keyboard, type combo : "Windows key + R"
In the command prompt, type : shutdown -o -r -t 0
it opens Windows Recovery menu:
Go to Troubleshoot -> Advanced Options -> Startup settings -> Restart
At reboot, hit 7 (Disable driver control) and follow instructions for Windows Vista/7.
when finished driver installation, reboot PC as usual.
- Windows Vista/Windows 7 :
Go to folder /Universal Naked Drivers 0.72 you unziped at start on your Desktop.
Select file android_apxusb.inf, then right click -> Install.
Force driver install and wait until a success message prompts.
Repeat operation with android_winusb.inf .
You can plug tab in USB for driver install completion.
Click to expand...
Click to collapse
Both installations responded "sucessful".
I then connect my TF300T to the PC with original charging/data cable, my PC doesn't seem to recognize the tablet. If I go to device manager, I will see an unknown USB with yellow (!).
What did I do wrong?
Thanks,

Please download the Asus PC Suite "ASUS PC Sync V1.0.97": https://www.asus.com/de/supportonly/ASUS Transformer Pad TF300T/HelpDesk_Download/
Install the PC Suite on your PC. Connect your Tablet with the PC via USB. Windows will ask for the driver. Point Windows on the folder of the PC Suite. The drivers will be there.

Still does not work.
*Windows did not ask for the driver.
*When try to update the driver through device manager (pointing to the folder:
ASUS Android USB Drivers
the result shows:
Update Driver Software - Unknown USB Device (Device Descriptor Request Failed)
The best driver software for your device is already installed
Windows has determined the driver software for your device is up to date
Same thing when I tried the "Universal Naked driver".

Look at this site: http://gsmusbdriver.com/asus-transformer-pad-tf300t. There you will also find "how to install the USB driver"!
PS: First of all, please check whether on your tablet "USB debugging" is checked on or not. If not check it on!
Then connect your tablet with the PC again. Open the device manager. If there is seen "Android Device" ->ASUS Android Composite ADB Interface or something like that and "Portable Devices"->TF300T, your tablet is known. Then you may check the driver if an update is necessary .

I've done all those things. I am wondering if my data cable is the culprit. Ever since Android 4.x.x whenever I am charging this tablet, and when the battery is 80% or higher, the screen will wake up and the speaker beeps. I have to mute the speaker and over the screen when charging.

Sorry for late reply, I have been on holiday.
All I know about f2fs is that Timduru recommends using it for data partition on his build. I just follow the experts advice when flashing.

djibe89,
Great job you did here!
Just a few comments. Timduru clearly emphasizes the following points in his installation guide and your guide may cause some confusion under the TF300T owners. I have seen newcomers on the Katkiss threads that had problems with their first install due to not following and using the prescribed versions and steps.
1) Timduru advises only to use twrp_tf300_kang_2.8.7.2.img and not TWRP 3.0.2-0
2) It is also suggested that UnLock_Device_App_V7.apk rather be used as some people had problems with V8.
3) He also suggests using UPDATE-SuperSU-V2.79-20161211114519.zip be used, but does not stipulate not using V2.52 which means this one is optional, your choice.
4) He also advises to ONLY change /data to from ext4fs to f2fs for /data and NOT to do this for /cache.
Just again, excellent job and thanks for sharing.

Hi, thx for posting.
I enhenced the tutorial with your statements.
However, for the TWRP and F2FS notes, it is related.
2.8 TWRP had problems with F2FS, and were buggy until latest 3.02-0. I have this version on all the devices I hack and have complete faith in it.
Enjoy.
See you

- Or restore a community TWRP backup with TWRP recovery (https://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860 see posts 2 & 3)
### With S-ON and keep device Unlocked
To find suitable backup for device, boot phone in Bootloader mode (Power + Volume-)
Look at your hboot version (hboot 3.19.0000 is most frequent)
Launch a fastboot command:
Code:
fastboot getvar all
Make sure IMEI is a valid number.
Look at your CID and MID values. Try to find exact same TWRP backups for your phone.
### Flash only exact model versions.
Then wipe all partitions and restore the correct TWRP backup an angel made for you.
- If TWRP restore fails, start with these posts :
You will need a Rom Update Utility (RUU) for your exact model version.
This is compatible with S-ON, will need to relock your Bootloader (save your Unlock_code.bin +++) and need original recovery

Hi, I updated pack with latest Magisk root version and checked download links.

For Windows 10 users, use HTC drivers version v4.17.0.001 - Download them from here - Zippyshare.com - HTC Mobile Driver v4.17.0.001.exe
Everything else works just fine. @djibe89 thank you.

Hi,
I'm at the stage of trying to unlock the bootloader. The phone restarts in fastboot mode but when i type in fastboot devices nothing happens.
and then if i skip that and type get_identifier_token. the return is waiting for any devices. and nothing happens.
What have I missed?
Thanks
i've since been able to get past this stage. I used htc driver 4.17. I'm now stuck on the token. cmd prompt keeps saying cannot load the file no such file or directory. but i'm so sure i have the file in the right folder

I've done this, then struggled a bit to pass safetynet, finally was able to install netflix, but it stays on boot logo and after a while gives me error 501 172. How can I make netflix work?

I'm back,
this tutorial worked like a charm for me at this hour: https://www.droidwin.com/how-to-pass-safetynet-on-rooted-android-12/

But I did pass the safetynet earlier, it is just the application still gave me error 501, 172. I will try to include missing steps because some are the same as I performed and see if application will run.

Add Netflix to Zygisk DenyList (+ other services like in Droidwin post) and clear Netflix app data

Done that once again (cleared app data of netflix and google play store, google play servcies and google services framework).
Unfortunately right now it is stuck on logo, and did not give me the error yet. Which method have you used?

Rom works pretty good on my K1, much better/faster than stock. Battery drain is still there but is nowhere near as bad on a stock rom (I have a brand new battery installed).
For some reason the headphone jack is not compatible with this rom at all (plugging in headphones does nothing). Anyone else notice this?
