Hi all,
Just followed the instructions below to get a new rom on my TF201.
Now I have Teamwin recovery booting showing V2.6.3.0 and asking for a password.
Teamwin does not show data in external or internal sdcards.
I am unable to get into fastboot mode, using power and vol down.
It has failed since running this line fastboot -i 0x0b05 flash recovery ne0zone75_tf300t.blob
I have all of the nvflash blobs etc.
Any ideas how to recover from this point?
Thanks
RR
This may help
Starting from a stock bootloader V 10.4.2.18
What you will need
Woking fastboot & adb / SDcard optional
TWRP for a 201 = twrp_tf201t.blob
@ne0zone75 TWRP for the 300 = ne0zone75_tf300t.blob
HairyBean BL & TWRP: This is effectively turn your 201 into a 300 <---- which is a flashable zip inside the zip that you downloasd
All 3 of the above file are in a zip in the Download section @ the top of every page of the thread ...... THIS ZIP IS NOT FLASHABLE...Your must unzip it to get to the real files !!! The name of this zip is 'upgrade_tf201_to_tf300t.zip'
CROMBI 201 ROM zip
A fully charged tablet
All the above files in the same directory as your fastboot.exe (if using windows) In your home folder on linux....
The process
Lets start with the TWRP recovery for the 201, let flash it with fastboot...
Power your tablet off and with the [ VOL DOWN & POWER ] buttons boot the tablet into the bootloader
Once there [ VOL DOWN ] untill the green box is on the USB ICON then [ VOL UP ] to select fastboot
Let make sure your PC can see your tablet with this command.
Code:
fastboot devices
Code:
fastboot -i 0x0b05 flash recovery twrp_tf201t.blob
Then
Code:
fastboot -i 0x0b05 reboot-bootloader
[ VOL UP ] ON RCK to enter recovery
Once in TWRP check to see if adb is working...
Code:
adb devices
Ok now that we know that is working let go ahead and push the HairyBean BL onto the tablet
Code:
adb push HairyBean_Bootloader_TWRP2.5.zip /sdcard
Now under the install tab in TWRP fine the folder and flash it....
reboot once it has fishined..If ask to install SuperUser say NO..........
LET THE BLUE BAR FILL !!!!!!!!! Once it has finished it will reboot into Hairybean TWRP....
Once booted into recovery, run this command to boot into fastboot
Code:
adb reboot-bootloader
You will see that the USB icon is missing now, this is good... If you still see the USB icon DON'T go to the next step
Now lets flash @ne0zone75 TWRP recovery
Code:
fastboot -i 0x0b05 flash recovery ne0zone75_tf300t.blob
Once that has finished let reboot into bootloader
Code:
fastboot -i 0x0b05 reboot-bootloader
Now enter recovery....
Make sure its verison 2.7.1.0
Go to Wipe////Format Data////Type yes
This can take up to 90 mins to format
DO NOT INTERRUPT THE FORMAT !!!!!!!
Now lets push CROMBI-KK onto your tab
Code:
adb push cm-11.0-2014xxxx-crombi-kk-tf201t.zip /sdcard
Find it under the install tab and flash it..
REBOOT into android, first boot can take up to 15 minutes
ADB interface working
Ok, lots of playing this morning tells me that the adb interface is working when the teamwin recovery is showing.
adb devices gives <number> recovery
Any ideas how to proceed from here, apart from carefully

Hello I was having a tough time trying to Flash Crombi KK rom. At 1 point I had to use a recovery blob because I was stuck. I started from there upgraded bootloader and twrp 2.5. Flashed twrp 2.8 and Crombi KK rom kept showing fail. I eventually gave up and tried to go from 2.8 TWRP back to 2.5 with JB Bootloader. Bad move I know. Whenever I pressed up to go to recovery it would get stuck. Then eventually I tried wiping data from Bootloader screen. Now the 3 options, recovery, coldboot and wipe data wont show. Stuck at Asus screen "The Device is Unlocked".
I downloaded naked drivers and android ADB drivers.. however I cannot get them to install on windows 7. I'd appreciate any help to try to this back running again

No blobs. I 've had this device since day one. Rooted it, bricked before but never this. I remember having a hard time making a NVFlashbackup for the same reason of my device showing up and eventually gave up. Any other suggestions?

I tried using this http://forum.xda-developers.com/showthread.php?t=2588979 to install ADB. It got to waiting for device and of course nothing. Is there something else needed to get the ADB to read the device? I downloaded the naked drivers as well but nothing showed up in device manager. No executable file to run. Am I missing something?

I'm keen to have specific instructions on how to recover from this point back to stock, then take a deep breath and try to get to custom.
My concern is that a lot of the threads with guidance for recovery and flashing are old, and I don't want to brick this thing.
So, is there a thread for recovery to stock from this point?
I have found this thread discussing recovery. http://forum.xda-developers.com/transformer-prime/help/guide-t2864946
am waiting for full charge of tablet at the moment.

You need the blob from the stock frimware downloaded from the Asus website ....
It will be in a zip file that needs unzipped twice ...... Make sure you get the correct 'SKU' for your tablet ......
Then follow this guide, skip to the first fastboot command and go from there .....

tf300 update required?
Ok, i seem to be failing when i apply neowin tf300 update, when following the crombikk instructions on post #4. The system does not now boot into recovery. Is this step absolutely required for the newer roms?

Did you get the message: Magic Value Mismatch:-.-.-.-.-.-?!
After flashing a new recovery it happens sometimes.
GREEN ZONE
Are you able to go to the recocery menu(power + vol up)? If not, go to BLUE ZONE. If yes, follow these steps
1. check whether you have copied your rom as "update.zip" to your SD card's root directory
2. Go to recovery menu and install update.zip
BLUE ZONE
You may did something wrong while flashing a new recovery. Here is the right method:
1. go back to fastboot mode(power+power+power+vol up) and type these commands on your PC
2. fastboot erase userdata
3. fastboot erase system
4. fastboot erase cache
5. fastboot erase linux
6. fastboot erase recovery
7. fastboot flash recovery recovery.img (change path, if recovery.img is not in the same directory as fastboot.exe)
8. fastboot reboot
Are you able now to go to the recovery menu? If yes, go to GREEN ZONE and follow steps. If not, go to ORANGE ZONE.
ORANGE ZONE
Are able to unpack the update.zip and find the system.img and boot.img files? If not, then go to RED ZONE. If yes, copy these 2 files to the directory where the fastboot.exe is, run these commands:
1. fastboot erase recovery
2. fastboot flash recovery recovery.img
3. fastboot -w
4. fastboot erase linux
5. fastboot erase system
6. fastboot flash system system.img
7. fastboot flash linux boot.img
8. fastboot reboot
ROM is installed. Enjoy it!
RED ZONE
Make sure, that you copied the same recovery.img to fastboot folder, that you had flashed before to your tablet.
Type this command in recovery mode:
1. fastboot boot recovery.img
This command will run the recovery from your PC. After the recovery menu is booted, go to GREEN ZONE and enjoy your ROM!
If this was helpful to you, please do not hesitate to click on Thanks!
Lol, nice to see my post copy/pasted without any links indicated. Anyway, I hope It's helpful for ppl.
Tried following these steps, however, I'm still getting this error... followed this thread

So you installed the recovery via fastboot. Did you manage to boot into recovery mode?
I had that issue, that I couldn't boot into recovery mod from my Folio, by pressing power+Up button. Thats why I added the RED ZONE method. Its like booting recovery from your PC. (fastboot boot recovery.img). All the times I wanna upgrade my current ROM, I have to do this step, because the power+up does not work, and the Folio skips booting in recovery and wanna do normal booting. However there is no Rom installed on machine, so I get the magic value mismatch message.
So try to boot recovery from your PC, but be sure you have copied to your fastboot folder the same recovery, that you flashed onto the tablet.
I hope it was helpful. If something is not clear, feel free to ask.
Hi there, thanks for the answer.
I am able to install recovery images via fastboot.
Device is showing up as a question mark with >fastboot devices
but recovery installs fine. CWM gives a series of e: can't opne/mount /cache errors.
Foliomod 1.4 installs no problem, thanks to the method here

Are you able to wipe cache from recovery? And what else errors are listed?
One more thing, try to flash your boot.img and system.img via fastboot as written above.
If I follow this
http://forum.xda-developers.com/showthread.php?t=1458876
and let it install cwm v 3, I get the cache error and cannot wipe or mount via recovery.
If I follow the ICS thread, and flash the new cwm v5 via fastboot, I don't get the cache error, but the rom simply won't start. If I open the package, there is a boot.img, but not a system.img, just a system folder...
I could try flashing boot.img, but I don't see how that could help

Well just to see it clear. So you are able to install Foliomod 1.4, so your Internal storage is not broken.
When I get home, I will check the system folder of ICS rom. There are some method to create system.img from an unpacked folder...
So, in CWM 5.5.0.4 you manage to install Zip from SD card, ROM and GAPPS as well, but the Rom does not boot?!
yup, that's exactly it.
Haven't tried installing Gapps since I can't even get the rom to boot.
I have a perfectly working tablet with foliomod 1.4, and I did get honeycomb to run but some apps crashed so I reverted back to foliomod.
with CWM CWM 5.5.0.4 everything seems to work great, except at reboot, nothing happens (somehow, I no longer even get the magic value mismatch)
------------------
PS. not sure if this is at all relevant, but I cannot fastboot from win7, I'm fastbooting in either ubuntu or xp via VirtualBox, and the device, when calling >fastboot devices shows up as ?????????? (ubuntu) and ? (xp)... :\

Hmmm strange. I ask it for you on developers forum. What you can still do, is to check the steps, that you did them correctly. In most of the cases users forget something, or do some steps incorrectly.
Try to erase userdata, cache, system, linux and recovery in fastboot. You mentioned you had problem with fastboot under Win7. Problem may occur, in case of not proper erasing.
Thanks, I'll give it another try tonight.
Fastboot in win7 is simply not seeing the device. It shows up in XP and Ubuntu, but as "??????" - not sure if that could be a symptom.
I'll post a reply as soon as I've tried, and let you know how it went.

For me it works perfectly on Win7. After Installing SDK and JDK the in the devicemanager it is shown as an Unknown device. Simply add the driver manually to it.
Download driver from attachment.
Copy it to SDK\USB_driver folder
That works for me. After its done, the Folio is shown as "Fastboot" in device manager. But connect the tablet in fastboot mode to your PC before you add driver manually to it.
Thanks for that.
Tried it, still not working in win7. It shows up correctly in device manager, but fastboot itself just doesn't want to see it...
I've attached a screenshot for you
EDIT: screenshot gets resized, but it shows device manager listing
NVIDIA Android Fastboot Device
and a terminal with fastboot not seeing the device

When You have win7, You have run the console as admin!
Or copy the complete Fastboot folder to another Destination like c:\temp...
Thanks stefannsv, tried it, still not showing...
But I can access fastboot on another platform, so I assume it's not an issue, I can just switch over to another OS to flash
no go, followed both this original post (tried all steps except orange, cause the rom I'm trying to install has a system folder, not a system.img)
Last method I tried was:
1) boot into fastboot
2) boot cwm-recovery-5.5.0.4.img directly from PC
3) wipe data/factory reset
4) wipe cache partition
5) install zip from SD card and chose the alpha 4 release
installing update...
then back to recovery, reboot and voilà... magic value mismatch again (it had disappeared for a while... )
Also, when booting into CWM 3.0.0.5, I get a series of "E: Can't mount/cache/recovery" type errors.. could this be related?
booting directly into recovery from PC doesn't alllow me to install any ROMS, not even foliomod 1.4 which works if using puppet13th's method
Yesterday, I unlocked and rooted my tf201, and proceeded to mess around with it. DL'd androwook, wiped everything and installed it. I think my mistake was choosing wipe internal SD when installing (it's where the installer was), and as a result, I was not able to get past the boot animation. I screwed around with it some more and eventually, after trying the Unbrick tool by MasterZen, was stuck at the splash screen with no recovery. Somehow, I had managed to screw up the boot and recovery. Oops.
However, I was able to fix it (boots normally, has recovery, etc..) with some knowledge of fastboot. This is what I did, as a complete amateur, so I probably can't answer specific questions and definitely cannot be held responsible for what you do to your tablet. Make sure you confirm files as non-corrupted with MD5s. This is basically a manual alternative to the Unbricker tool by MasterZen.
I used:
fastboot & adb
TWRP recovery twrp.blob
Ubuntu for Android boot image
[Optional] Stock .28 for unlocked (blob from inside the zip), which you will need to rename (system.blob)
Put these blobs in the folder with your fastboot.
1) get tf201 into fastboot (hold volume down + power on), connect to PC
2) command prompt, "cd [directory fastboot is in]"
3) "fastboot devices" & confirm your device is seen, otherwise go to devmgr and uninstall tf201 drivers and install the Universal Naked Drivers.
4) "fastboot -i 0x0b05 flash recovery twrp.blob" - flashes recovery so you have TWRP. You could try CWM if you'd like.
5) "fastboot -i 0x0b05 flash boot prime-sdlinux.blob" - flashes main kernel.
At this point you should be able to shut down, hold down volume down, and boot with the option of getting into recovery. In recovery, you could use ADB to push a specific rom you'd like and install zip from there. Alternatively, if you want to be able to boot into the system, and have downloaded the stock .28 for unlocked devices and placed the blob inside the folder with fastboot, you can type into command prompt:
6) "fastboot -i 0x0b05 flash system system.blob[or whatever you named it]"
And you should be able to boot up normally.
I've rooted and messed around with android phones before, but honestly I don't know enough about it to give 100% confident answers, and as such cannot be held accountable for what you do to your own device. I figured if someone also had this problem and wasn't able to get the Unbricker tool to work, they could benefit from what I learned. So good luck! Leave questions and feedback, and I'll do my best to answer.
Thanks to blade2k11, who in this post, made me realize that the main kernel was screwed, and that's why I couldn't access the recovery, and that I could fix it with the bootimage from the Ubuntu for Android post.
Thank you sooo much. This brought life back to my tablet!

Did you download the stock .28 rom and take out the system blob? Have you checked the MD5's to make sure they're downloaded without any corruptions?

Assuming you have access to adb, put the rom file in your adb folder you have been working from, in windows, right click the rom file, go to properieties, copy the name of the file.
In your adb command box you opened from within your adb folder (pressand hold shift while right clicking select command prompt here) type adb push then right click and paste the name of the rom you copied followed by .zip
This should take about 5 minutes to transfer, go get a coffee or something.
Once done, boot into recovery (twrp)
Under install you should see the rom, install, after the reboot you should be good....
i got stuck in a bootloop trying to unbrick, i can boot into recovery using this but when i try to transfer a rom with adb it gives an error that /sdcard is read-only so i cant put my rom on it. i tried using the stock .28 blob but im still in the same bootloop. not sure what else to
Deleted... whew!
Thanks guys for the help. I'm back up and running

Long time lurker and I appreciate all the work everyone does here. It makes owning an android device a great amount of fun...but as you can see by the title of the thread, a great amount of stress as well :laugh:
My device is unlocked and I've used CWM and recenlty noticed that along one of my flashes TWRP 2.4 installed over CWM. All is well because I was meaning to switch over and try this recovery out. Smooth, fast, I like. But I recently installed CM 10.1 using the october version with the JB bootloader because I did not have it. Everything was nice, but I wanted to update CM 10.1 to a more recent UNOFFICIAL build so I flased the 3/20 version on my device. Everything was smooth but the WiFi dropped all the time so I decided to wait out a more stable "official" version of CM 10.1. Take note that I have(had) TWRP 2.4. Now I wanted to stick with JB 4.2.X so I decided to flash Energy's 3/21 build but this hung up on the ASUS screen... So I decided to reflash the rom but first installing the JB bootloader and partitions zip. Still no luck and while exiting TWRP, I noticed that it stated that my device isn't rooted and would I like to root? So I swiped and did it but it seems that the JB bootloader and partitions zip file erased everything on my device, Roms, GAPPS, SU, backups...gone.
The next thing I did was execute Urkels fresh root and fresh start and that seemed to go through all the steps with no issue. When I went back into recovery I noticed that I now have TWRP 2.2.2.1 with a JB bootloader... so what ever I did downgraded TWRP? Ok... Now I wanted to play it safe and stick to the October version of CM 10.1 with the JB bootloader but while flashing the rom (ext SDCARD) i receive an error. I decided to re-execute Urkels fresh root and fresh start and now all my device does is boot into TWRP 2.2.2.1. I can't use fastboot even with holding the power button and vol down.
At this point I feel lost and defeated, I can't use external SD anymore and I can only mount the system. So I decided to see if ADB works. ADB works great in recovery and am able to send files to the device. I sent a ROM to see if I can install but it fails because it can't mount the cache and this is where I am now. Lost... confused and desperate for help :crying: I'll make sure XDA gets a nice donation if anyone can help me out!
What works -
boot to TWRP 2.2.2.1 (thats all)
ADB in recovery
What doesn't-
No rom installed
No backup
No fastboot
My troubleshooting
Again ANY help is appreciated!
Mike
Would I be able to update TWRP within TWRP using a 2.4.4.0 zip file?

This is happening because you are now on 4.2.1 bootloader with an old TWRP which is not compatible with the new bootloader.
When you say you cannot access fast boot do you mean the usb icon is missing? If you do that is part of the new bootloader. As soon as you get to where the icons are you are automatically in fast boot unless you select one of the icons.
I'm out at the moment but if you reply letting me know that you can get to the icons I will post a file when I get back and some instructions to downgrade you to old bootloader and compatible TWRP.

I figured my TWRP version might have been the culprit...
When I restart and hold the vol down button it normally would activate fastboot, now it goes directly to TWRP, no icons whatso ever. Before I would get the recovery icon, a usb (I think) and an option to wipe data. I can't get to that screen anymore. Is there a command in adb that will allow me to restart to fastboot from recovery? I myself am at work too so I will test anything I can in 3 - 4 hours. Thanks for taking the time to respond! :good:
So basically I won't be able to put TWRP 2.4.4.0 within my current version of TWRP?

The version of TWRP you have will not mount the partitions you need to flash anything. You either need to downgrade the bootloader so that version of TWRP will work or get the version of TWRP back on there that was edited to work with the new 4.2.1 bootloader.
When you installed that partition.zip from energy rom it installed the new bootloader and the compatible twrp the same time. To go back he also has a zip that will restore old bootloader and old twrp. This is what you should have done.
What I am worried about now is the fact that you cannot even get to fastboot from the buttons.
Try adb reboot bootloader.
If that lets you in then download this .. http://flumpster.lolcakes.com/android/blob and place it in your fastboot directory.
Now type.
fastboot -i 0x0B05 flash staging blob
wait for it to fully flash and then type
fastboot -i 0x0B05 reboot
Give it about 20 seconds, if it doesn't restart then you will have to hold the power button down for 10 seconds to force a restart.
When it restarts it should now start to fill the blue line on the Asus screen which will flash the old bootloader and compatible TWRP. If it does this then great, just wait until it has finished and it should put you back into twrp where you will be able to install a rom off your external SD.
If it does not do the blue line then we have bigger probs and I hope you have nvflash backup files.

Crossing my fingers... I will try what you mentioned and no, I don't have NVFLASH. Something that I have been meaning to do for a few weeks now too. Thanks for the help I will update when I get a chance to try.

You cannot do the nvflash process now. You could only do it while on ICS and there is no way back to ICS without having nvflash backups.

I am able to adb reboot bootloader, and it brings me to fastboot!
I successfully executed the steps you gave me but I didn't get the android screen with the blue line... it went back to TWRP 2.2.2.1. Can I fastboot the new version of TWRP?

Tried one more time with no success... Please let me know if I have any other options since I can get to fastboot via ADB.
I think the reason I am running into this mess is because I didn't download the JB update from ASUS and move the system.blob file according to Urkel fresh start

I was worried about this. I have seen loads of people with the same problem you have over on the tf300 forums.
They can access fastboot thru adb reboot fastboot and it appears to send the file over ok but then it doesn't work.
When you mentioned you couldn't get to fastboot by holding button combo it looked like the same prob as them.
Have a look at this thread. http://forum.xda-developers.com/showthread.php?t=2179874

So I probably need to send it to ASUS or wait for a solution? That is for the TF300 would I be able to use any steps for that device with mine?
Also,
I purchased this in January 2012 from best buy, any possibility I can go through them to have this issue fixed?

Flumpster thanks a bunch for all of your help. I ended up sending in the tablet, as expected they had to replace the motherboard.:
They quoted me this origionally:
Parts: $165
Labor: $65
Shipping $10
TOTAL $240!!!
I called and complained until my eyes popped out of my head and they ended up replacing the motherboad and shipped it back to me for $150. Now I think I'm going to sell this thing with the dock and buy a Nexus 10. Again, thanks for your help.
Another note... It will probably be a pain to unlock and root this thing again after the RMA im assuming. No more ASUS.
Hi All,
I'm trying to get into the correct state to be able to use a custom rom, following the instructions below.
When I get to the
Code:
fastboot -i 0x0b05 flash recovery ne0zone75_tf300t.blob
step, it flashes, but then the device will not enter recovery.
Is this step required for Crombikk or the Lollipop Roms?
I can get the hairybean bootloader on, does it matter what version of TWRP is on the tablet?
The first version that you flash using the instructions below works ok.
Thanks

UPGRADE INSTRUCTIONS, STEP BY STEP
This may help
Starting from a stock bootloader V 10.4.2.18
What you will need
Woking fastboot & adb / SDcard optional
TWRP for a 201 = twrp_tf201t.blob
@ne0zone75 TWRP for the 300 = ne0zone75_tf300t.blob
HairyBean BL & TWRP: This is effectively turn your 201 into a 300 <---- which is a flashable zip inside the zip that you downloasd
All 3 of the above file are in a zip in the Download section @ the top of every page of the thread ...... THIS ZIP IS NOT FLASHABLE...Your must unzip it to get to the real files !!! The name of this zip is 'upgrade_tf201_to_tf300t.zip'
CROMBI 201 ROM zip
A fully charged tablet
All the above files in the same directory as your fastboot.exe (if using windows) In your home folder on linux....
The process
Lets start with the TWRP recovery for the 201, let flash it with fastboot...
Power your tablet off and with the [ VOL DOWN & POWER ] buttons boot the tablet into the bootloader
Once there [ VOL DOWN ] untill the green box is on the USB ICON then [ VOL UP ] to select fastboot
Let make sure your PC can see your tablet with this command.
Code:
fastboot devices
Code:
fastboot -i 0x0b05 flash recovery twrp_tf201t.blob
Then
Code:
fastboot -i 0x0b05 reboot-bootloader
[ VOL UP ] ON RCK to enter recovery
Once in TWRP check to see if adb is working...
Code:
adb devices
Ok now that we know that is working let go ahead and push the HairyBean BL onto the tablet
Code:
adb push HairyBean_Bootloader_TWRP2.5.zip /sdcard
Now under the install tab in TWRP fine the folder and flash it....
reboot once it has fishined..If ask to install SuperUser say NO..........
LET THE BLUE BAR FILL !!!!!!!!! Once it has finished it will reboot into Hairybean TWRP....
Once booted into recovery, run this command to boot into fastboot
Code:
adb reboot-bootloader
You will see that the USB icon is missing now, this is good... If you still see the USB icon DON'T go to the next step
Now lets flash @ne0zone75 TWRP recovery
Code:
fastboot -i 0x0b05 flash recovery ne0zone75_tf300t.blob
Once that has finished let reboot into bootloader
Code:
fastboot -i 0x0b05 reboot-bootloader
Now enter recovery....
Make sure its verison 2.7.1.0
Go to Wipe////Format Data////Type yes
This can take up to 90 mins to format
DO NOT INTERRUPT THE FORMAT !!!!!!!
Now lets push CROMBI-KK onto your tab
Code:
adb push cm-11.0-2014xxxx-crombi-kk-tf201t.zip /sdcard
Find it under the install tab and flash it..

4 originally.
When I flash the Hairybean bootloader, 3
I think the intent of the question is to see if I have managed to get the bootloader on?
I think that I have as I no longer have the USB icon.
Thanks

Fix to be able to install CrombiKK and Lollipop
Hi All,
In answer to the question posed in the OP, these are the steps I used to be able to install Lollipop on my TF201.
They are slightly different from Josh's instructions, as I used the latest TWRP for a TF300T, after I flashed the Hairybean Bootloader. Ne0win blob did not work for me.
These steps worked for me. I also flashed the gapps package and TF201 compatability linked to in the original Lollipop thread.

Posting this to help others struggling for the first time to flash their tf201.

My TF201 was fine with stock 4.1.1 installed. I didn't have to enter a password to open it. Pressing power button was enough to reach the home screen.
I decided to install Nougat so I followed the thread "from stock to nougat" step by step (which is a great threat btw) but, of course, something went wrong.
I need help with getting the device out of the current status, which is :
- Only TWRP 2.6.3.0 is installed. I press Down + Power but no '3 icons' appear anymore.
- When I enter TWRP I get asked for a password. I highly doubt that I've (ever) set a password but somehow the device is now encrypted (?) / password protected. I can bypass the password screen by simply clicking 'cancel' but still can't mount anything inside TWRP, not system or external sd card, nor can I unzip / flash a Rom.
Before TWRP (this morning) HairyBean recovery was installed, but I couldn't flash anything there either, it ended always in an "can't unzip" error.
The good news is when connected to Win10 I have a working fastboot and adb connection !
What should be the next step to solve this (and to reach Nougat) ? How can I get the 3 icons back ?
You have the wrong TWRP installed for Nougat v7.1, you have to be on TWRP 2.8.0.0 or higher. You should flash the highest version available to date. LATEST TWRP: https://androidfilehost.com/?fid=457095661767150802
The BIG question is, what BOOTLOADER are you on? I think you have to be on bootloader version 10.6.1.27.1 to get the TWRP to work.

Last bootloader is from the HairyBean-Upgrade zip :
Upgrade+Hairybean+2.31+(4.2.1)+Bootloader+&+TWRP+( 2.5).zip
But again, I couldn't flash anything either. It all ended with "can't unzip" error.
Right now, I can't boot into fastboot. The device always boots into TWRP 2.6.3.0.
I did the steps on this page : [HOW-TO] Unbrick your Transformer Prime (or not) by Diamondback
- Type: "adb shell"
- You should see a "#" now
- Once you have that "#", please type: dd if=/dev/zero of=/dev/block/mmcblk0p4 bs=100 count=1 and press [Enter]
- Now type: dd if=/dev/zero of=/dev/block/mmcblk0p3 bs=16 count=1 and press [Enter]
- Exit the shell and reboot your Prime via CWM
- It should not reboot to CWM automatically now. It either boots your ROM or is stuck at the splash screen. If it is stuck, boot to recovery and install any ROM you want.

but the result is the same, the device ONLY boots into TWRP (and asks for a password).
Without being able to boot into fastboot, how can I install the latest TWRP ?
So holding the VOL bottom down when turning on the tablet doesn't bring to the screen with: [RCK] [ANDRIOD] [WIPE DATE] choices in the middle?

No. But I can send "adb reboot bootloader", and then it comes up after reboot.
So I've tried 2-3 times to flash recovery with :
fastboot flash recovery twrp-3.1.0-1-tf201t.img
but it always hangs at "writing 'recovery' ".
The device freezes.
Any suggestions what I should do now ?

Btw, bootloader is "WW_epad-10.6.1.27.1-20130711".
Have to tried renaming the TWRP.img file "TWRP.blob" then;
fastboot -i 0x0B05 flash recovery c:\adb\TF201t\TWRP.blob (you will need the to input the location of the file on you computer, that is where I flashed mine from) also did you wipe the recovery partition?

Two questions before I totally brick my TF201 :
1) how to I wipe recovery partition ? (note: In fastboot mode, is it the third 'wipe data' icon ? does that wipe recovery, too ?)
2) the page says "THIS LINK IS FOR TF201 RUNNING JB BOOTLOADER ONLY! DO NOT USE IT IF YOU ARE NOT SURE WHAT YOU ARE RUNNING STOP NOW!".
How can I be sure what bootloader I'm on ?
(the text at the top of the page where the 3 icons are says :
HTML:
Key driver not found.. Booting OS
Android cardhU-user bootloader <1.00 e> released by "WW_epad-10.6.1.27.1-20130711" A03
Starting Fastboot USB download protocol
WW_epad-10.6.1.27.1 - 20130771 A03 is the JB bootloader, same one I'm on. You just have to wipe the recovery partition using adb command;
fastboot erase recovery
Then
fastboot -i 0x0B05 flash recovery c:\TWRP.blob
Once you get the TWRP from the link working you can flash the new ROM using the TWRP recovery console.

I've tried many things, but right now when I try to enter recovery it says in red "unrecoverable bootloader error (0x0000000)"
fastboot erase system <- this end with an OK
fastboot erase recovery <- this doesn't end at all, command never ends
fastboot erase misc <- same as "erase recovery", doesn't end
flashing any blob, or any file doesn't end. Flashing blob says "sending.." and then doesn't continue, it is stuck there.
I also put the zip from inside the Asus blob zip onto an SD card, but since I don't have a recovery I can't start the process. -> unrecoverable bootloader error
So whatever I tried, it doesn't succeed. Either the tablet is stuck (the green RCK icon stops blinking) or it does nothing at all, for example after issuing a "fastboot flash recovery.." command, it just blinks the whole time and nothing happens.
The only successful commands are (so far) "fastboot reboot-bootloader" and "fastboot erase system".
Any suggestions are welcome..
Ok, good news, I have TWRP 3.1.0-1 installed.
I had the SD Card inside the tablet. the "unrecoverable bootloader error" was on screen.
The filename inside SD card is "EP201_SDUPDATE.zip".
So I did a Volume Down Button + Power button long press (as I did so many times before) and rebooted the tablet.. and somehow it recognized the zip file and started updating the system.
So, an Android robot appeared with a scroll-bar beneath it, and the the Android robot changed to a dead one with a red X on it.
After rebooting the tablet again I saw 4 icons, so that is the ICS bootloader, right ? at the top it says now "WW_epad-10.4.2.18-20121122" A03
Nevertheless I just flashed the latest TWRP through fastboot command.
Next I'll try to install a custom Rom.
But before that, do I need HairyBean recovery or bootloader first ?
Edit : I followed the steps here and everythning went fine so far. The tab is rebooting right now.
Thanks for your help !!
I'm using KatKiss 7.1.2 on my TF201 found here

Ok, good news, I have TWRP 3.1.0-1 installed.
I had the SD Card inside the tablet. the "unrecoverable bootloader error" was on screen.
The filename inside SD card is "EP201_SDUPDATE.zip".

You know need to install the JB bootloader but you're fine with TWRP,
The correct bootloader for the ROM is: WW_epad-10.6.1.27.1 - 20130771 A03
