Problem with step 8 - INSTALL Android 6 ROM

Hello djibe89,

First of all, I would like to thank you very much for this well documented step-by-step guide for upgrading the TF201! It was no problem for me, a novice in this, to follow.

However i do have encountered a problem with booting after the installation of step 8. And i hope you are able to help me with this. When i try to boot the device after Successful installing KatKiss-6.0_TF201_029.zip, open_gapps-arm-6.0-pico-20160320.zip, and Beta-superSU-v2.52.zip, the device seems to be in a boot-loop. The OS never starts up.

I also tried the older KatKiss-6.0_TF201_028.zip with the two other zip files, but the result is the same.

Until step 8, all installations went without major problems. (i made a document from your instructions and documented every step i did, (including serial number received from fastboot etc). So my TF201 is now Unlocked and the bootloader TWRP is at version 2.8.3.0.

There is only one thing i received at step 7, wich i think i should mention. When i do Wipe -> Format Data, i receive the following message when it's Done:

Updating partition details ...

... done

Full SELinux Support is present.

(in red) E: Failed to get default contexts and file node for storage files.

MTP Enabled

Formatting Data using make_extfs function

You may need to reboot recovery to be able to use /data again.

Updating partition details ...

... done​

I did not pay attention to this message, because there was also the Successful message.

But perhaps it does have something to do with my problem of not being able to boot into KatKiss.

Hope you are able to help me with this.

(Maybe i will try to install Nougat for the TF201, since the recovery with TWRP is OK.)

Kind regards, Bert

Hi, I'm glad you liked it.

Seems like you chose wrong Filesystem format " Formatting Data using make_extfs function".

We need a F2FS partition.

Go back to your TWRP 2.8 recovery,

wipe all partitions,

chose /data partition and change filesystem to F2FS.

Make sure /Cache partition is F2FS too.

Then you can Install the zips.

Keep in touch.

Merry christmas from France

Hello djibe89,

Thank you for answering my question.

But before receiving your answer I was already trying to do the steps again (from step 4), which was (looking back) obviously a bad idea. I am afraid I made a mess of it right now. First of all i should have read the error msg carefully to see the file system type. I was aware that

this

KatKiss is using f2fs?

I already send you a pm describing what i had done, and that i had to stop experimenting until after Christmas :)

Today (27 dec.) i tried an other attempt to revive my tab, and started by: 2ND PART, NvFlash---

Got the tab in APX mode again (Windows Device Manager shows Asus T. P. APX..)

So i went on with 5 - RECOVERY

I do get the fastboot screen; with the menu's RCK - Android - USB - Wipe Date, and went to USB.

Giving the command fastboot devices gives the serial number, so its connected.

Then i gave fastboot -i 0x0b05 flash recovery twrp_tf201t.blob which gave

sending 'recovery' <7934 KB>...

OKAY [2.213s]

writing 'recovery'...

OKAY [ 3.534s]

finished. total time: 5.747s​

then a reboot bootloader with: fastboot -i 0x0b05 reboot-bootloader

After this i had the TWEAMWIN screen again.

with adb devices i get the 012345678ABCDEF recovery message. So, adb can connect.

But re-installing HairyBean_Bootloader with

adb push HairyBean_Bootloader_TWRP2.5.zip /sdcard​

gives an error on the tab.

Then i realized that i have just re-installed TWRP 2.6, which is intended for JB bootloader! So i booted the tab to fastboot and installed the TWRP 2.8 with:

fastboot -i 0x0b05 flash recovery twrp.blob That went OK.

Now i tried to install KatKitt6 again, now with all partitions formatted as f2fs.

But i stil don't get Katkitt6 booting. It keeps rebooting.

===============================================================

Today, 28 dec. i did an other attempt and made photo's from the screen of the tab.

From within TRWP 2.8.3.0, I started at Step 7 – SET FILESYSTEM TO F2FS

Wipe :: Format Data, uses ext4 filesystem (as described in the tutorial) and takes indeed a long time.

Next Wipe :: Advanced Wipe ONLY the data folder, and set to F2FS

Also with the Cache partition also set to F2FS

Step 8 – Install Android 6 ROM. From TWRP Wipe :: Advanced Wipe. Select Dalvik Cache, System, Cache and Internal Storage. Swipe to cleanup. NO mention of changing the filesystem to F2FS so I left these as they are!

Installation of the tree .ZIP files, see pictures below:

Unfortunately, i am only able to put links to photo's when i have at least posted 10 posts. Since i am new here i try an other way of linking to the photos:

Step 7 and 8 - Photo 1 https: // deltabert.stackstorage.com/s/gszDWyVd9sqHiQs

Step 7 and 8 - photo 2 https: // deltabert.stackstorage.com/s/Ju0tmwMIUjJXHg4

Step 7 and 8 - photo 3 https: // deltabert.stackstorage.com/s/o0tTQ3tPBHF85Wu

Step 7 and 8 - photo 4 https: // deltabert.stackstorage.com/s/Cls41PHHcCa0TKr

And when I press Reboot, after Wiping Dalvik Cache, the tab keeps rebooting! This time I see no error messages.

And believe me, I left it booting for hours…

Any idea as what I could do next?
[Asus  Eee Pad Transformer Prime] ALDO_MAC12:
did you ever get through this part?

im on the same boat.....finished everything successfully but once i install the ROM it keeps rebooting and stays on the TWRP until i reboot again
[Asus  Eee Pad Transformer Prime] deltabert:
Hi ALDO-MAC12,

Unfortunately, i have not yet got my TF201 working. I'l wait now until djibe89 has time to react.

(When i opened his zip file i noticed he has also a France language description, and he is at the moment in France, So i guess he is a French-Canadian, on vacation in France.)

I did study the original posts from timduru and TacoNikky, but i can find no differences with the description of djibe89. Noticed there is also a Android 7 rom from timduru. But i think i should first get to manage the hole process.

For me all this is new. My tab became so horribly slow that i only sparsely used it anymore. So that's why i would like to give it a try.

BTW, i do get the tab in APX mode; with volume up and power, i get a black screen but in Windows Device Manager there shows up the Asus Transformer Prime APX ... driver.
[Asus  Eee Pad Transformer Prime] lazuhrus:
If you're running Windows 10, you need to delete all your other android drivers, then disable the signature checking on your driver installation and install the Naked Universal driver.

Super SU wants update

Works for me on windows 10. Make sure tablet is plugged in directly and not into keyboard also. Although Super SU is now reporting an update in necessary. Is it recommended in update Super SU after installation? Btw thanks for bringing new life to my tablet!
[Asus  Eee Pad Transformer Prime] shaDNfro:
Have you tried not to change /cache partition to f2s2. The original KatshMallow thread says:

...
[Asus  Eee Pad Transformer Prime] deltabert:
Hello all,

Thank you for thinking with me, I appreciate this very much! I will react to the suggestions given.

[MENTION=4001520]lazuhrus[/MENTION], I think the Universal Naked Drivers 0.72 are correctly installed on my Win-10 PC. I followed the procedure for Win-10 to disable driver control. To confirm this: I am able to use fastboot from Win-10; fastboot devices gives me the serial number of the tf201.

Also the command adb devices gives me: 012345678ABCDEF recovery.

Further, when I bring the tf201 (with volume UP and power) in APX mode, I get a dark screen on the tab, but in Windows Device Manager there shows up the Android device: Asus Transformer Prime APX Interface.

So for me this seems OK. This lets me conclude that the Universal Naked Drivers 0.72 are correctly installed and working. Or am I overlooking something here?

Btw, I do this on the bare tablet, without the keyboard dock.

With volume DOWN and power, I get the tab in TWRP version 2.8.3.0.

And installing KatKiss seems to go well (see the screenshots I posted in #10 from the TWRP format and install process).

@ shaDNfro, I did change the /cache partition to f2fs, as the screenshots are showing too.

However, there is one strange thing. After the last install (post #10) when I am in TWRP and connect the tab to my PC (win10) I see in the File Explorer an entry for an ASUS Transformer Pad TF300T; while mine is an TF201!!

Picture File Explorer: https: // deltabert.stackstorage.com/s/Nj1C01jTyZ5MoWB

And in the Device Manager I see also references to the wrong tab type!

(But you can see the Asus Android Composite ADB Interface.

Picture Win10 Device Manager: https: // deltabert.stackstorage.com/s/zK2LIoAthr4jKJ7

(added spaces around // because i am as novice not (yet) able to post links)

Hopefully anyone can help me with this...
[Asus  Eee Pad Transformer Prime] djibe89:
Hi guys,

I am French from France indeed ;)

- Maybe try to reformat the /cache partition in EXT4 (instead of F2FS).

Then wipe all partitions and install all zips again.

- It is normal that your tab is seen as TF300 as the TWRP 2.8.3.0 is originaly openrecovery-twrp-2.8.3.0-tf300t.blob.

I no longer have my tab so it's tricky to help you. I'll try anyway ;)
[Asus  Eee Pad Transformer Prime] deltabert:
Thank you djibe89,

I really hope you can help me with this, I become a little desperate...

I wonder if there is something wrong with the bootloader (HairyBean_Bootloader_TWRP2.5.zip). When I boot the tab with vol-down and power I get the following bootloader info: Android cardhu-user bootloader <1.00 e> released by â€œWW_epad-10.4.2.15-20120917â€ A03

Do you know if this is correct?

OK, I put the tab in TWRP 2.8.3.0 mode.

Formatted the /Cache partition using make_ext4fs

Then I wiped Dalvik Cache, followed by /System, which formats to ext4fs.

Then format /Data, first with make_ext4fs, and when finished, I change the filesystem of /Data to f2fs. Wiped all other partitions, except Micro SDcard (not sure if this is the internal or external SDcard)

Then I installed the three .zip files. KatKiss-6.0_TF201_029.zip, open_gapps-arm-6.0-pico-20160320.zip and BETA-SuperSU-v2.52.zip.

I also put the MD5 checksum file of KatKiss-6.0_TF201_029.zip on the sdcard and the install procedure checks the .zip successful.

When install is done: Successful, I wiped Dalvik Cache and rebooted the tab.

But then I have the same reboot problem: First i see a blue bar for one second, then the tab boots with the ASUS splash screen at medium intensity, then switches for a moment to high intensity and back to medium intensity, and after a few seconds it reboots and it starts over again.

When I leave the tab booting for two hours, I can feel it is doing something; the backside is becoming slightly warm; processor: ~ 45Â°C.

The bootloader is part of HairyBeen isn't it? Could I re-install the correct HairyBean_Bootloader_TWRP2.5.zip again, by putting it on the external sdcard and selecting it from TWRP 2.8.3.0?

fastboot, adb and Nvidia APX Mode are still functioning, so there must be a solution...

Hopefully you have a good suggestion?

Kind regards, Bert
[Asus  Eee Pad Transformer Prime] djibe89:
Yo Bert,

you must be in distress.

Maybe it's time to look for a NVIDIA APX restoration.

I hope you still have your backup files.

I don't know anything about it,

so read all Google carefully to proceed.

That's why I motivated you to backup APX in my tutorial, since we never what can happen with Android hardware.

Keep in touch
[Asus  Eee Pad Transformer Prime] deltabert:
Hi djibe89,

I will look into the restoration option. I do have the APX backup files.

Will be continued....

I have the revers X-axis on mine when I'm in TWRP so I use a USB mouse with the keyboard dock. Now with that bootloader I don't think TWRP 2.6.3 will work, you might have to flash back to TWRP 2.4.4.0, I just don't if you need the ICS or JB version. You can find the TWRP here: https://dl.twrp.me/tf201/

Once you get 2.4.4.0 installed and working you can then flash bootloader version 10.6.1.27.1 found here: https://androidfilehost.com/?fid=23060877490002899 this will also install TWRP 2.5.0.0

From diasjairo

I too have this same problem and cant seem to advance from here!
[Asus  Eee Pad Transformer Prime] Nektopoli:
1st question is have you unlocked the stock tablet's bootloader using the tool from Asus? -NP
[Asus  Eee Pad Transformer Prime] AuroraDelta:
Yes the stock bootloader is unlocked. I get the "The device is unlocked" message in the top left corner of the screen when i turn the tablet on.

Thanks.
[Asus  Eee Pad Transformer Prime] Nektopoli:
You might need to push the bootloader zip file from the adb directory on the computer and not the sd card. - NP
[Asus  Eee Pad Transformer Prime] AuroraDelta:
I tried again unlocking the bootloader and i removed the google account first. The tablet is now stuck trying to boot. it seems to be stuck trying to unlock the bootloader. I can't get into any recovery mode only APX mode. The tablet will turn on for 1 second then reboot.
[Asus  Eee Pad Transformer Prime] Nektopoli:
Can you access the tablet from a computer or laptop using "Minimal ADB and Fastboot"? - NP
[Asus  Eee Pad Transformer Prime] AuroraDelta:
No i cant access the tablet at all! I tried "adb reboot-bootloader" and "fastboot reboot-bootloader" but they can not detect the device.

I cant even turn the tablet off when it gets stuck in the boot loop. I have to let the battery die.
[Asus  Eee Pad Transformer Prime] Nektopoli:
Is the computer running Windows 7, 8 or 10? - NP
[Asus  Eee Pad Transformer Prime] AuroraDelta:
Im using Windows 7.
[Asus  Eee Pad Transformer Prime] allancoblu:
Hi, Firstly many thanks for this great tutorial, my TF201 has been hidden away for some while as I couldn't get it to charge. Have started to play with it again as I found the cause (dodgy usb lead and PSU).

I haven't done anything like this for a few years so I have been taking it slowly and so far so good, I've finished part 1, but I'm immediately confused by Part 2:

"2ND PART, NvFlash	----------------

Copy these 7 files in the folder "files/nvflash" (Another copy, in addition to the backup you made).

Connect tab to PC."

Where are the 7 files copied to? I created the first copy and placed them on a usb drive and the originals are still in the NVflash folder which is in the Files Folder, so where does the 2nd copy go?
[Asus  Eee Pad Transformer Prime] markelmad:
Hi, first of all, thank you so much for this detailed instruction. I am on the installing the bootloader stage. unfortunately, my device has broken digitizer so can't do any on-screen clicks. Is there a way to install zip files on TWRP using ADB? I can only use my PC, volume btns and power button to interact with the device (tf201). Also tried a mouse and keyboard dock with no luck. Sideloading seems unlikely an option as well coz i still need to go to advanced page of TWRP (using touch again).

Thanks in advance.
[Asus  Eee Pad Transformer Prime] plascoch:
Thanks for a great guide

Hi my wife bought a tf201 about a year ago it was useless always locking up and stating browser / any other app is not responding do you want to close or wait, virtually unusable except for minor tasks. She who must be obeyed told me to fix it so that it could be used properly. I came upon this guide and voila after about 4 hours of reading and updating we finally have a a very usable tablet. The ICS implementation on the tf201 is rubbish Asus should be ashamed at leaving the device with such an unusable operating system.

Once again big thanks for the guide and to the guys who developed the katkiss version of nougat.:):)
[Asus  Eee Pad Transformer Prime] djibe89:
I'm glad you did it !

I remember it took me more than 5 days when no tutorial was available !

Enjoy
[Asus  Eee Pad Transformer Prime] B3nihana:
Did you manage to fix this? I have exactly the same issue trying to flash that hairybean rom, device is unlocked via the official app mentioned in the instructions.
[Asus  Eee Pad Transformer Prime] chrisps:
Same... does anyone know how to get past this?

I have unlocked the device (It says "This device is unlocked" while booting).

I have installed TWRP, which shows it is version 2.6.

When I then try to flash the Hairybean bootloader in TWRP, it only takes a second or so, doesn't ask anything about SuperSU. I reboot the tablet, a blue bar appears for a second or so, then the tablet reboots into the normal OS.

I have tried various versions of HairyBean and all have the same problem. Do I need a different TWRP?

Thanks!

Is anyone still having problems with google play services after doing all this? I just hate to do all this work and still get the play services error. I have 2 Tf101 tablets and this Tf201 and i update the play services and youtube and other google app just wont work.
[Asus  Eee Pad Transformer Prime] plast59:
First of all thanks for this guide, I've been fed up with my TFP for some time and I gave this change a go (though I'm a noob in this kind of things...).

Everything went alright (but I had to update twice drivers on W7, on step 4 and step 6) up to step 6, of course I made a mistake... On step 6, I installed SuperSU...

I now have the HairyBean TWRP recovery on, but I don't want to continue without fixing this.

Can someone tell me how to uninstall SuperSu and "Unroot" the device ?

Or is it not necessary ?

Furthermore, the device is not recognized in W7 anymore, and I can not install the special driver from the "Drivers android_winusb if hairybeen TWRP not recognized" folder.

W7 says (translated from French) : "Windows found a driver for your device but an error occurred while installing / "Asus Transformer ADB Interface" : the specific file was not found".

Any ideas ?

Thanks in advance for the support.
[Asus  Eee Pad Transformer Prime] Nektopoli:
[MENTION=9782695]plast59[/MENTION], if you have a working TWRP and an unlocked TF201 why not move forward and install KatKiss 7.1? - NP
[Asus  Eee Pad Transformer Prime] plast59:
Actually, I managed to go further and get the TWRP Kang 3.2.3-0 Recovery ( I just rebooted and typed the prompts without entering Androwook, which was logical...).

BUT, some part on my screen on the right is not responsive anymore, so I can't swipe the button to allow changing the System Partition...

And at this point the deck doesn't work so I can't use the touchpad either...

What a mess...
[Asus  Eee Pad Transformer Prime] plast59:
Well, with a subtle combinations of finger touches, I did it !

Went all the way up to step 10 and the new Transformer Prime is here !

Indeed it feels like a whole new tablet.

Thanks a lot again to djibe89 for the tutorial and everyone involved in this project :good:

GREAT, glad you got it going. - NP

I just dug out my old TF201 which I had given up on completely since their last official update basically made it worthless. I ran through these steps and have it up and running again. Now I have no desire to go out and buy myself a new tab!!

Doing this on Linux

Hey guys, first of all, thanks for this amazing tutorial and for the work the dev keeps doing for the custom rom of this old hardware (hope he can read this).

So I was trying to find a step by step guide for doing this on Linux (Debian), but I just couldn't, and because I'm not very tech savvy, I just began following the steps here (commands are the same for Windows and Linux, and I could find most of the software).

I got to successfully complete step 4 until the first part (bootloader is unlocked, backups until that part are safe). But when I got to the second part, I couldn't find nvflash, and most importantly, wheelie, for Linux. Anyone has any leads to where I can get them?

Also, has anyone seen a step by step guide like this one for Linux users?

I really don't wanna continue without doing the wheelie part, and don't have access to a Windows machine. I know it's optional, but this is my first experience with 'bootload unlocking'/rooting/'custom rom flashing' for any device, I don't really wanna brick it.

Thanks in advance.
[Asus  Eee Pad Transformer Prime] djibe89:
Hi, glad the tuto helps you.

You are right, saving wheelie blobs is really necessary.

Find a Windows 7 or 10 anywhere, it is already complicated, using Linux will make it even more difficult.

See you,

JB
[Asus  Eee Pad Transformer Prime] sven23:
Ok, so just after posting this, I found the tools for Windows and Linux (nvflash and wheelie) over here:

https://github.com/AndroidRoot/androidroot.github.io/blob/master/download/tf201_nvflash.zip

With those, I was able to finish the process and my TF201T is working better than ever before.

I'll come back here if I try different configurations.

About my experience, couldn't find App Battery Calibration (from IMobS Ltd) on Play Store, ended up downloading a different Battery Calibration App:

https://play.google.com/store/apps/details?id=com.blogspot.superthomaslab.batterycalibration

Seems to work fine, both the dock and the tablet's battery did really good from 100% to 0% after calibration.

Went for the 1600 Mhz overclocking for now. Readhead 1024. Seems to work fine. Although I didn't spend any time without overclocking so I got no reference.

In a nutshell, you can follow this tutorial on Debian. You don't need the windows Asus drivers on Linux. You can get Fastboot and adb from the official Debian repositories. And you can download nvflash and wheelie binaries for Linux from the link I posted before. All the other files, you can get from this tutorial (APKs, and thingis for the Tablet).

Hope this helps someone.
