Thanks

---------- Post added at 08:38 PM ---------- Previous post was at 07:51 PM ----------

OK I flashed the New Bootloader and TWRP and the Prime went to OS not back to TWRP so I rebooted to Recover( I used the Power Menu option to reboot to Recovery) but on the Video enclosed the the new TWRP is indicated as the new 2.6.0 at the top of the Screen my TWRP still looks like the old TWRP was installed when I went to 2.2. Should I see new 2.6.0 somewhere? I did not want to go to Wipe and install 2.3 ROM until I was sure.

Thanks
[Asus  Eee Pad Transformer Prime] flumpster:
Look at the top left of the settings page.
[Asus  Eee Pad Transformer Prime] RonH54:
Nope....Nothing is indicating it 2.6 there. Would it mattered that I rebooted to Recovery via the Power Menu option that was included in 2,2 with Stock Kernel instead of Button Method?

Edit: I shutdown Prime and went to recovery via Buttons and still no indication I am on 2.6 TWRP. When I flashed new Bootloader and TWRP I saw the "blue line" indicator showing it was updating so I am not sure the deal. I sort feel I am on 2.6 because the TWRP went to my Internal Storage as location of Zip files when before I had it set to go to my External SD card.
[Asus  Eee Pad Transformer Prime] flumpster:
Look in the wipe menu. Do you see loads of separate wipe options or do you just see an advanced button, data and a slide to factory reset.

Hi all,

I am new to this thread and a noob. I have followed the TF201 HairyBean 2.31 Noob guide posted by bpc23. Thanks to bcp23. I successfully completed from 1st step in the guide to the NvFlash to generate the blob files and to save all the images. Now I am at the last step to install the 2 zip files, Upgrade+Hairybean+2.31+(4.2.1)+Bootloader+&+TWRP+(2.5).zip and the Hairybean+2.31.zip. I used my pc to format the Micro SD card to FAT32 and copied these 2 files to the Micro SD card. I put this card to my TF201 tablet slot and reboot into the recovery mode. In CWM recovery which is left over from the NvFlash, I only saw "install zip from sdcard", and "install zip from sideload". There was no option to install zip from Micro SD. If I chose the "install zip from sdcard", I only saw the "apply /sdcard/update.zip". What is this update.zip file which I don't recognize it? Should I see the option to install zip from Micro SD? Is it because recovery cannot mount the Micro SD causing it not to show up in the recovery menu? I did a normal boot and I can see the external Micro SD and its contents. What can I do to install these 2 zip files? Please help and thanks in advance.
[Asus  Eee Pad Transformer Prime] Nektopoli:
I'm going to jump in and ask a few basic questions first;

1] Are you on a stock unmoded TF201 tablet?

2] If no to No1, have you unlocked your bootloader using the Asus unlocker?

3] Have you rooted your TF201?

NP
[Asus  Eee Pad Transformer Prime] tintin888:
Thanks for the responses. Here are my answers to the questions.

1) Yes, my TF201 is unmoded initially before I installed anything.

2) Yes, I unlock the bootloader by running Unlock_Device_App_V6.apk (based on the TF201 HairyBean 2.31 Noob guide -post 1772 posted by bpc23)

3) No, I did not root the TF201 since the TF201 HairyBean 2.31 Noob guide or the [ROM][Aug 29][JB 4.2.1] AndroWook Prime HairyBean v2.31 **Unleash The Beast!** does not mention that TF201 needs to be rooted.

I did some research in this thread and there are someones here encountered the same issue. They re-installed the TWRP2.6.3.0 (recovery/fastboot) and they were able to see the install zip from MicroSD and installed the Hairybean2.31. So, I re-installed the TWRP2.6.3.0 and I successfully installed the Upgrade+Hairybean+2.31+(4.2.1)+Bootloader+&+TWRP+( 2.5).zip and the Hairybean2.31.zip from MicroSD card (followed the steps in the TF201 HairyBean 2.31 Noob guide). After installing Hairybean2.31 and restarting the tablet normally, I am able to setup the tablet such as language, keyboard, time, etc.... The tablet boots up completely and I can swipe the unlock screen and see the menu screen . However, the tablet hangs and reboot itself. It keeps doing that. Basically, I can not use it since it keeps rebooting itself when it is in the menu screen.

Do you know why it hangs and keeps resetting itself? Did it brick my TF201?
[Asus  Eee Pad Transformer Prime] tintin888:
Also, when I boot in recovery, the bootloader still the old one. Here is what on the left corner at recovery.

Android cardhu-user bootloader <1.00 e> released by "WW_epad-10.4.2.15-20120917" A03.
[Asus  Eee Pad Transformer Prime] Nektopoli:
Ok when you boot in the recovery console, what bootloader version is your tablet on?

[Asus  Eee Pad Transformer Prime] tintin888:
I also ran MD5 on these 2 zip files and they all match.
[Asus  Eee Pad Transformer Prime] Nektopoli:
Tintin, do you want to use Android 4.1 or are you trying to install the bootloader so you can flash Android 7.1 on your TF201?

If you're trying to go to 7.1, I would try ONLY flashing the bootloader and TWRP found here: https://androidfilehost.com/?fid=23060877490002899

Then check and see if you are now on the correct bootloader version [10.6.1.27.1] once you correct the bootloader issue you

can upgrade the TWRP and flash any ROM you want 4.1 / 5.1 / 6.1 / 7.1.2 (the one I'm currently on)

NP
[Asus  Eee Pad Transformer Prime] tintin888:
That is the link I used to download and install Upgrade+Hairybean+2.31+(4.2.1)+Bootloader+&+TWRP+(2.5).zip, but the bootloader did not get updated. I have tried two times and the same result. I am not sure what went wrong. I plan to go to 7.1 like your. Any suggestion to install Upgrade+Hairybean+2.31+(4.2.1)+Bootloader+&+TWRP+(2.5).zip? Do I need to root the tablet in order to install this bootloader?
[Asus  Eee Pad Transformer Prime] Nektopoli:
I rooted my TF201 using the video here, that could be causing the hang up; https://www.youtube.com/watch?v=ggpsVortObY

NP
[Asus  Eee Pad Transformer Prime] tintin888:
In the TWRP2.6.3.0 recovery, when I do reboot, it says "Your device does not appear to be rooted. Install SuperSU now? This will root your device". Should I install SuperSU to root the device and try to re-install the Upgrade+Hairybean+2.31+(4.2.1)+Bootloader+&+TWRP+(2.5)?
[Asus  Eee Pad Transformer Prime] Nektopoli:
SuperSU is used to manage a rooted device, I would root you TF201 (using MotoChopper) like in the video, then install the correct bootloader.

NP
[Asus  Eee Pad Transformer Prime] tintin888:
I just watched the video. It looks like you need to be in stock ROM. Do you know how to put my TF201 back to stock rom? I did save blob.bin, bricksafe.img, factory-config.img through nvflash.
[Asus  Eee Pad Transformer Prime] Nektopoli:
What ROM are you on, I say that because other then the TWRP it looks like you're still on the stock bootloader and ROM

NP
[Asus  Eee Pad Transformer Prime] tintin888:
The bootloader is still a stock one. I am not sure how to tell the version of the ROM. I think the ROM is Hairybean2.31 since I check the About tablet the Android version is 4.2, instead of 4.1.1. How to thell the ROM version?
[Asus  Eee Pad Transformer Prime] Nektopoli:
Go to [SETTINGS] then at the bottom, under [ABOUT TABLET] is will tell you "Android X.X.X"

NP
[Asus  Eee Pad Transformer Prime] tintin888:
That what I did. In About tablet it says Android version is 4.2, instead of 4.1.1. Currently I cannot use motochopper to root since my tablet hangs and reboot itself when boot up.
[Asus  Eee Pad Transformer Prime] Nektopoli:
It might be rooted, I would go ahead with the SuperSU install, reboot, and see if SuperSU starts to ask for permission.

NP
[Asus  Eee Pad Transformer Prime] tintin888:
I will install the SuperSU to root and I will provide update. If it does not work I might need your help to restore the stock ROM. Thx

---------- Post added at 11:44 PM ---------- Previous post was at 10:58 PM ----------

I install the SuperSU from TWRP. Then I reinstall the Upgrade+Hairybean+2.31+(4.2.1)+Bootloader+&+TWRP+(2.5).zip and Hairybean+2.31.zip. it still does not work. My tablet still hangs and reboots itself after few minute of booting up. I check the bootloader again and it is still the stock bootloader "Android cardhu-user bootloader <1.00 e> released by "WW_epad-10.4.2.15-20120917" A03. ".

I think I need to start from scratch. Do you know how restore stock image?
[Asus  Eee Pad Transformer Prime] Nektopoli:
One thing, do you have a Windows 7 computer or laptop, you might have to flash the Hairybean files from ABD and fastboot, it might not be allowing the TWRP 2.5 to overwrite the newer 2.6 on there not.

NP
[Asus  Eee Pad Transformer Prime] tintin888:
[/COLOR]

My laptop does not work on ABD or fastboot. I use Window 7 pc for ABD and fastboot.

I look at the post #1273 page 128 in this thread , and this person has the same issue. He downgraded to TWRP2.5 from TWRP2.6.3.0 as you suggested. He stated "I did that and worked fine. Now I just noticed that when I load "Upgrade Hairybean 2.31 (4.2.1) Bootloader & TWRP (2.5).zip" via TWRP2.5 and it reboots to flash it, the message: "signature mismatch" is displayed in the top left corner and the push is cancelled", and there is no follow up threads of how to solve it. Thus, if I downgrade to TWRP2.5 manually, I will end up "signature mismatch" when I install "Upgrade Hairybean 2.31 (4.2.1) Bootloader & TWRP (2.5).zip" via TWRP2.5. So I am not sure this is a good option.
[Asus  Eee Pad Transformer Prime] Nektopoli:
When you get to the Install Zip screen in TWRP to flash the HairyBean file is the box next to "Zip Signature Verification" UNCHECKED ?

NP
[Asus  Eee Pad Transformer Prime] tintin888:
Yep, the "Zip Signature Verification" was UNCHECKED. I did try one time with this box check and it failed due to no MD5 file. However, I did run the MD5 tool on these 2 zip files and they all matched.
[Asus  Eee Pad Transformer Prime] Nektopoli:
Here's the link to the driver's for out TF's: https://www.asus.com/us/supportonly/Eee Pad Transformer Prime TF201/HelpDesk_BIOS/

And a direct D/Load link to the file: http://dlcdnet.asus.com/pub/ASUS/EeePAD/TF201/US_epaduser_10_4_2_18UpdateLauncher.zip

But it looks like you will have to flash the original ROM with fastboot shown here: https://xdaforums.com/transformer-prime/help/help-reverting-to-stock-rom-t2949423

NP
[Asus  Eee Pad Transformer Prime] tintin888:
Thanks, I will try to revert back to the stock ROM. and will provide status.
[Asus  Eee Pad Transformer Prime] tintin888:
Thanks for your help, Nektopoli . Now my tablet is back to stock ROM. Everything is running fine now. Do you thing I need to root my table in order to install Upgrade+Hairybean+2.31+(4.2.1)+Bootloader+&+TWRP+(2.5).zip and Hairybean+2.31.zip? If I root my table, do I need to install OTA RootKeeper?
[Asus  Eee Pad Transformer Prime] Nektopoli:
Try flashing the Bootloader and TWRP only, see if that gets you on the correct bootloader -> 10.6.1.27.1 Once you fix the bootloader issue, update to the TWRP to KANG's TWRP 2.8.5.1 and from there you can flash TWRP 3.1.0-1

After you update to the most current TWRP then start flashing the ROM, GAPPS and SuperSU.

NP
[Asus  Eee Pad Transformer Prime] tintin888:
Thx. So, I can flash the Upgrade+Hairybean+2.31+(4.2.1)+Bootloader+&+TWRP+( 2.5) without rooting the tablet. Is that correct? If it is correct, I will do that this weekend to see whether I can get the correct bootloader 10.6.1.27.1. Please confirm.

Also, I just re-read the guide, and I am confused. I am not sure how to flash the Upgrade+Hairybean+2.31+(4.2.1)+Bootloader+&+TWRP+( 2.5) . Should I use the TWRP2.6.3.0 or use the Nvflash to flash it. I am just afraid it will end up the the same issue that I encountered. Do you have a way to flash Upgrade+Hairybean+2.31+(4.2.1)+Bootloader+&+TWRP+( 2.5).zip file?
[Asus  Eee Pad Transformer Prime] Nektopoli:
It looks like you flash the new bootloader and TWRP 2.5 using the stock Asus recovery console and the file on a microSD card. I don't have the stock recovery anymore.

"1) Boot into recovery and flash "Upgrade Hairybean 2.31 (4.2.1) Bootloader & TWRP (2.5).zip" from Micro SD card.

2) Click restart after completion and on restart LET THE BLUE LINE FILL ALL THE WAY, WHEN IT IS FINISHED IT WILL RESTART ITSELF BACK INTO TWRP OR INTO OS.

3) If the Tablet does not boot back into TWRP or OS then hold down Power and VOLUME DOWN for 10 seconds until it restarts and the icons appear. Then select RCK manually."

NP
[Asus  Eee Pad Transformer Prime] tintin888:
I install TWRP2.2.2.1 successfully and then I use this TWRP version to install "Upgrade Hairybean 2.31 (4.2.1) Bootloader & TWRP (2.5).zip" from Micro SD card. It is installed successfully with no error. When it restart, this time it takes some time to fill the blue bar. When the bar is filled, it reboots back to recovery and at the left corner I can see that the bootloader is "ww_epad-10.6.1.27.1-20130711" A03, and I can see 3 icons(but no USB icon). I power off the tablet, do the normal power on, and it boots to stock ROM successfully. Then, I power off the tablet and power back on into the TWRP and it is version 2.5. I notice now my computer does not recognize my tablet USB any more. I am not sure why. Then in TWRP, I accidentally go to Mount (Mount icon), mount the system and power off the tablet. When I do normal power on and the tablet stays at the ASUS screen and does not boot into the stock ROM anymore :(. I am not sure what happens.

Edit: I am able to recover the PC to recognize the tablet USB in fastboot, ADB, and APX mode. I reinstall the "Upgrade Hairybean 2.31 (4.2.1) Bootloader & TWRP (2.5).zip" again, and normal boot still stay at ASUS screen and does not boot into the stock ROM.

Can mount the system in TWRP wipe out the stock ROM?

Nektopoli, please help to recover the ROM. Can I still use your procedure in post #1804 to recover the ROM?
[Asus  Eee Pad Transformer Prime] Nektopoli:
Right now don't worry about the ROM, once you get TWRP 3.1.0-1 you can install the KatKiss ROM v7.1.2

But 3.1.0-1 is an .IMG file and TWRP 2.5 wont flash image files, so you update to TWRP 2.8.5.1 here: https://androidfilehost.com/?fid=95916177934539154

Then you can update to 3.1.0-1 found here

THEN you can flash the new ROM.

NP
[Asus  Eee Pad Transformer Prime] tintin888:
Thanks for the response. Over the weekend I found out that the bootloader 10.6.1.27.1 does not work with stock ROM and I thought I bricked my table. As soon as I flashed the Hairybean2.31, everything works fine. I will uninstall the Hairybean and take your suggestion to install TWRP 2.8.5.1 and TWRP 3.1.0-1 then KatKiss ROM v7.1.2. Thanks for being patient.

Can you provide the link for TWRP 3.1.0-1 and KatKiss ROM v7.1.2?
[Asus  Eee Pad Transformer Prime] Nektopoli:
You don't really have to "uninstall" the old ROM, you wipe the system partition before you install the new ROM and that cleans off the old ROM

just make sure you get the TWRP installed before making the jump to 7.1, installing the wrong TWRP will brick you tablet.

So right now you're on 2.5 from here install 2.8.5.1 and then 3.1.0-1 then follow the instructions and install 7.1.2

TWRP 3.1.0-1 for our TF201s can be found here: https://androidfilehost.com/?fid=457095661767150802

The ROM here: https://xdaforums.com/devdb/project/?id=16947#downloads

[Asus  Eee Pad Transformer Prime] tintin888:
Thanks Nektopoli. I installed the TWRP 2.8.5.1 successfully from the 2.5. Then I installed the 3.1.0-1 image. In the isntall image there were 2 options, Recovery or Boot. I chose the Recovery. The 3.1.0-1 image was installed successfully. I reboot the tablet and went to recovery and it got an error in red. On the upper left corner of the tablet, it said the following:

[Asus  Eee Pad Transformer Prime] Nektopoli:
When you boot into the Fastboot menu, can you access the recovery console via the green RCK button?

Do you remember when you flashed the the TWRP if you checked the [STAGING] button?

NP
[Asus  Eee Pad Transformer Prime] tintin888:
I recovered the TWRP 2.5 and the bootloader 10.6.1.27.1. I used install zip to install TWRP 2.8.5.1. When I in TWRP 2.8.5.1 "install" menu, I don't see any [STAGING] button. So, I am not sure where this button is. When I choose "install image" from 2.8.5.1, I only see2 options, the Recovery or the Boot. Which option should I choose? Last time, I chose the Recovery, and I got the error.

Also, I found this thread https://xdaforums.com/transformer-prime/help/guide-tutorial-asus-transformer-prime-t3486237 which shows how to install TF201 stock to Android 7.1 Nougat. Should I use this guide?
[Asus  Eee Pad Transformer Prime] Nektopoli:
Ok, there's one step in TWRP3.1.0-1 that might get missed from time to time, so it might get missed with 2.8.5.1.

Before you flash the ROM you have to make sure you MOUNT the system partition, this is done from the main TWRP page;

Click [MOUNT] > Check box next to [SYSTEM] (top line under [Select Partitions to Mount:])

Click [Select Storage] (Bottom kind of centered, grey button)

You will get a pop-up, check circle next to [Internal Storage]

Also, you can toggle between [INSTALL IMAGE] and [INSTALL ZIP] on the page where you select the TWRP image file, it won't show the image file

if you have ZIP selected and vice versa.

And you should select [RECOVERY] when is give you the option, not [SYSTEM]

You are no longer using a "Stock" tablet because of the custom recovery.

NP
[Asus  Eee Pad Transformer Prime] tintin888:
Thanks. I just want to make sure I understand what you said. In order to install the TWRP3.1.0-1 image, I need to use the TWRP 2.8.5.1 to do a MOUNT to system partition. When I in the TWRP 2.8.5.1 main page, I select "MOUNT" and I see the "System" box is uncheck, the "Cache', "Data", and "Ext/card" boxes are check. I check the "System" box, but do I need to uncheck the the "Cache', "Data", and "Ext/card" boxes are?
[Asus  Eee Pad Transformer Prime] Nektopoli:
Yes, you must check the box next to system to make any changes, this also much be check to flash the ROM and support .zips files

leave the other boxes as they are.

NP
[Asus  Eee Pad Transformer Prime] tintin888:
Ok, I mount the System by checking its box and leave , the "Cache', "Data", and "Ext/card" boxes alone (checked). Then click the "Select Storage" and select "Internal Storage".

Since my tablet currently is at stock ROM 10.6.1.27.1, I might try the the Stock to 7.1 thread. If I have any questions, I can post them there and you can answer there. The Stock to 7.1 thread thread is more appropriate for my update.
[Asus  Eee Pad Transformer Prime] Nektopoli:
Without a working TWRP I wouldn't. Do you have a Windows 7 computer/laptop handy, you will need to install "minimal adb and fastboot" on the computer/laptop so you can flash TWRP from the Windows 7 system.

Minimal ADB and Fastboot: https://xdaforums.com/showthread.php?t=2317790

Once you can access the TF from a computer/laptop you can get a working TWRP on it, you have the correct bootloader on it now but I didn't know

you lost the recover console.

Installed the wrong TWRP - how to fix?

Hi everyone, I messed up my installation of AndroWook and I was wondering if somebody can help me turn back time.

What I did is install AndroWook (JB 4.2.1, HairyBean v2.31) on the TF201. Then many years passed and then I got back to the TF201 and wanted to install another ROM. I had forgotten about AndroWook so I flashed a custom TWRP (for TF201), which I could get into but then it asks me for a password, and can't seem to mount the partitions. It's a very similar situation to what is described here: https://xdaforums.com/showthread.php?t=2480790 with the exception that I could get into fastboot mode. But when I am there, flashing has no effect. I tried to flash another TWRP and it says it's completed, but then when I boot into recovery nothing has changed.

Does anybody know what is the best way to return to having a functional TWRP? I am fine with the one from AndroWook - I suppose I could take the ZIP and try to flash it from my current TWRP but I hesitate because it doesn't seem to be working well so I worry it would brick the device.

Any help most appreciated! Have a great day everyone.
[Asus  Eee Pad Transformer Prime] Nektopoli:
You are wiping the recovery partition before flashing the correct TWRP? [fastboot erase recovery]

NP
[Asus  Eee Pad Transformer Prime] florisvanvugt:
I didn't, actually (sorry I am really new to this). So I should run that command before flashing TWRP? And can you advise me at this point, which TWRP should I flash? One from AndroWook or one from dl.twrp.me/tf201/ ?

Thanks, appreciating your help a lot!
