[GUIDE/TUTORIAL] Asus Transformer Pad TF300T Any version to Android 7.1 Nougat / Lineage OS 14.1
This detailed step-by-step guide helps you transform your Asus Transformer Pad with Android 4.2.1 to a powerful one with Android 7.1 Nougat.
This worked for me only with USB2.
Make sure you have latest official updates in Settings -> About -> Update (While connected to Internet).
To check your tab is the correct model, go to Settings -> About. 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*
Under kernel informations, tap 7 times on "build info" to unlock the developer options menu.
################# TO GO FURTHER, your BOOTLOADER MUST END IN 27.1 or 27.5.
### If not : see the end of this tutorial.
### I'll make a few notes using this style : PLEASE READ THEM.
How to know which bootloader version I have ?
Shutdown tab. Hold Volume- AND Power buttons till tab boots in bootloader.
On top line of the screen is written : ... released by "US_epad-10.6.1.27.5-datetime" A03 (so I have *.27.5 version. US can be CN, WW, or other letters).

Go to Settings -> Developer Menu -> check USB debugging.
- Windows 8/10 :
On keyboard, type combo : "Windows key + R"
In the command prompt, type :
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.
- Copy the UnLock_Device_App in internal memory
Tab should normaly be seen in Windows explorer as TF300.
Check MTP file transfer protocol is active on the tab.
Copy the UnLock_Device_App_V8.apk in the root folder of the tab.
3 - UNLOCK BOOTLOADER of Transformer Pad TF300T
Tablet must be fully charged to 100 %.
In Android, go to Settings -> Security -> Check Unknown Sources.
Then Settings -> Developer options -> Enable USB debugging.
Launch the preinstalled app : File Manager to install UnLock_Device_App_V8.apk.
### If it fails to install, delete your Google Account. Go to Settings -> Accounts. Delete the Google Account.
### If it fails again , manually set date and time of your tab.
### If it still fails, register on
https://www.asus.com/support/
### Timduru advises to use UnLock_Device_App_V7.apk :
http://dlcdnet.asus.com/pub/ASUS/EeePAD/TF300T/UnLock_Device_App_V7.apk.
### At least you know it, but V8 worked perfect for me.
Launch the UnlockApp.
Accept User agreements.
### YOUR WARRANTY IS NOW VOID (but I presume it is already).
Accept and click to unlock the tab,
let the tab restart and work.
After reboot , "This device is unlocked" is written on top left screen during boot logo.
### If it fails, manually set Tab date and time to local time.
4 - FLASH TWRP3.1 RECOVERY
Charge tab to 100% before continuing.
Start it in bootloader mode (Hold Power + Volume- till you see 3 icons).
Connect it to PC.
Open a 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
In Windows command, type :
Code:
fastboot devices[CODE].
If the serial number is written, tab is well connected.
### If not : Check Universal Naked drivers installation.
### NB. Timduru advises to use exclusively TWRP Kang 2.8.7.2 : https://www.androidfilehost.com/?fid=24052804347781183
### But this 2.8 TWRP has huge problems with F2FS. You can chose my version TWRP 3 or the official one ;)
Now type :
[CODE]fastboot -i 0x0b05 flash recovery twrp-3.1.0-0-tf300t.img
### OR
Code:
fastboot -i 0x0b05 flash recovery twrp-3.0.2-0-tf300t.img
if you are using the TWRP recovery from my zip.
and wait for the "finished" success message,
then type :
Code:
fastboot -i 0x0b05 reboot-bootloader
and confirm with Volume+ to get into RCK (recovery, again), it is now TWRP 3.1.0-0 (or 3.0.2-0 if you used the .img from my zip)
###### FROM NOW ON, ONLY USE TWRP TO WIPE DATA OR PARTITIONS, never again the Bootloader Wipe data icon.
5 - SET FILESYSTEM TO F2FS
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 cecked.
Now Select Storage -> 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.
Now chose Back (to Advanced Wipe Menu).
Select /cache partition -> Repair or Change File System -> Change File System -> F2FS, Swipe.
### If you used TWRP 2.8 Kang, let cache in EXT4 filesystem.
Go Back and back to Advanced Wipe Menu.
Select /data partition -> Repair or Change File System -> Change File System -> F2FS, Swipe.
Tap on Home button.
6 - INSTALL Android 7.1 Nougat + Root
Still on TWRP Home screen, Install -> Storage: Internal Storage and change it to microSD card -> OK.
Select KatKiss-7.1_TF300T* .zip, and Add More Zips,
superSU-2.79*.zip, and Add More Zips,
then open_gapps-arm-7.1-pico*.zip and Swipe to force install.
Be patient.
### If it fails, install zips 1 by 1, make sure microSD is valid and that you downloaded OpenGapps ARM 7.1 PICO version.
Custom ROM is installed and system is rooted.
When done prompts, tap on Wipe Cache/Dalvik and swype to confirm, wait.
Then Reboot System.
Let the tab start (at least 10 minutes).
7 - ANDROID 7.1 Nougat
On Android first launch, immediatly manually toggle Wifi ON or you'll run into an app crash.
Configure Android as you like.
Go to Settings -> Performance
Check Set clock values on boot
For Maximum frequency, select 1600 MHz.
In Settings -> Mediascanner filters, uncheck Scan.
In Settings -> About, tap 7 times on build number, it unlocks the Options for developers in Settings.
Enter this new menu.
In the Hardware acceleration, verify that GPU rendering is checked.
8 - CALIBRATE BATTERY
In Google Play Store, download App Battery Calibration (from NEMA, IMobS Ltd).
Launch the App.
Confirm root access.
Plug tab and wait till charge hits 100%, then hit BATTERY CALIBRATION and unplug it.
9 - OTHER APPS
- You can use GPS Status & Toolbox for faster GPS fix.
- Kernel Adiutor to overclock

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.
