That is working but that is not my problem. I am scripting a restore process to run at scheduled times and everything is working until it gets to the point where it needs to reboot to android after the restore.

Again, the restore command works and it lists my device when I run "adb devices" but "adb reboot" will hang. I did notice that the "ASUS Android MTP Device" has an exclamation point next to it in device manager which might mean something but everything else is working fine. I have tried several different drivers and have not been able to get it installed properly. It is driving me crazy!

Edit: I am having this same issue on the TF300, too.... :(
[Eee Pad Transformer Android Development] sidneyk:
I'll look into further, but I think I noticed the same thing that adb reboot didn't seem to work from recovery. I wasn't trying to script anything though so it wasn't a deal breaker for me. I'll see if I can determine whether it is by design or not. I know mtp is working for me in linux, I'll double check windows again. Of course, I may be using a newer adb driver and different USB drivers.
[Eee Pad Transformer Android Development] ccb1208:
adb reboot is not working on my linux box either. I actually checked on the twrp website for the TF300 and apparently this is a known issue right now. I am hoping there will be a resolution or work around soon enough but in the mean time, I am going to have to wait.

Update TWRP

Been using KatKiss-KitKat-ROM and very happy with it. Time to move on to Lollipop.

For the installation TWRP 2.8.1 is recommended. I'm still on 2.3, so I have update to 2.8.1.1

What is the easiest way to do this? I downloaded the new zip, but how to install?

I installed the older recovery on my TF101 with EasyFlasher (Frederuco's Guide to Root and ROM the TF101)

In that guide update is suggested with GOO Manager, but that isn't supported anymore.

Can I flash the new recovery with my current recovery or should I use something like TWRP Manager?
[Eee Pad Transformer Android Development] MatteoB92:
Being called 'flashable', install the zip just selecting it into recovery
[Eee Pad Transformer Android Development] Agret:
I wiped my /system because I was trying to flash KatKiss-Lollypop. Didn't have a new enough recovery though (2.3.x) so I just flashed the latest unofficial TWRP flashable but it didn't work properly as i'm stuck in a boot loop. There is no way to boot android as there is no system image installed. I don't want to lose anything on /sdcard (the internal storage) as I just did a titaniumbackup of all my user data onto it. Would like to somehow flash the TWRP and my ROM. Gonna look for a guide :) I'm going away tomorrow so really need to get this fixed for my trip ahhh

Edit: Okay so the solution is to download the Universal Naked Driver and use EasyFlasher to reflash an early version of TWRP. No matter how many times I try to flash the flashable TWRP from within that it just fails to boot that recovery though, something must be broken with the unofficial version. Shame.

Edit 2: Yep, was able to upgrade from the EasyFlasher TWRP 2.2.1 to the openrecovery-twrp-2.3.2.3-tf101.blob by using the dd method but going from that to signed_twrp-2.8.1.1_tf101.zip also results in being unable to enter recovery. Can confirm the 2.8.1.1 is broken for SBK1 TF101's (I imagine the dev uses an SBK2 and hasn't noticed any issue)

Edit 3: Great news is that the KitKat verison of KatKiss only requires 2.3.2.3 TWRP so you can still run KitKat on an SBK1. Unfortunately if you have an SBK1 you are out of luck as far as running Lollypop is concerned but at least you still have a recent ROM =) Great device that it can still keep up these days.

Edit 4: Up and running on KitKat now, didn't even have to reinstall my apps as they came across and upgraded from JellyBean. Time will tell if KitKat runs better/more stable than Jellybean on this device. Maybe I can download some sort of Lollypop material theme for the system. :good:
[Eee Pad Transformer Android Development] doppelhelix:
I don't think it has anything to do with SBKx. My device is SBK1 and I don't have any problems
[Eee Pad Transformer Android Development] Agret:
Well any version other than the unofficial version runs fine so I don't know how to explain it, unless I need to modify my partition table somehow but that isn't mentioned at all on any of the threads they say you just upgrade straight to it by flashing the zip or if that doesn't work use DD. Tried both methods and no-go. KitKat is running great btw :)
[Eee Pad Transformer Android Development] sidneyk:
Same here, my device is definitely sbk1 and I have no issues with either method of flashing 2.8.1.1. Are you you grabbing the MD5 file also to confirm you have a good file to flash? In fact, I've tested it on 2 sbk1 devices.
[Eee Pad Transformer Android Development] sidneyk:
Should work fine for the 2.8.1.1 in first post. I test with an sbk1 device before releasing.
[Eee Pad Transformer Android Development] Duchman:
First of all, thank you sidneyk for your continued work on this device, you and timduru are truly keeping it alive.

Now for my issue: I can't move any files to my device using MTP while in recovery. I've tried it from my PC running Windows 7 and with UND installed, then I booted Ubuntu from live USB, and lastly I tried it on my netbook running Linux Mint. If I try to move a folder, it is created and copying process window pops up, but the bar isn't moving. If I play around with enabling/disabling MTP in the recovery, the device isn't recognized anymore until I reboot the recovery (Linux gives "unable to mount" error). "Mount USB storage" doesn't work either, but I guess you disabled it since you said it was interfering with MTP. I've tried reflashing the recovery, but to no avail.

Thanks again
[Eee Pad Transformer Android Development] sidneyk:
I'll try to get a newer version up when I can where mtp works better. In the meantime you could use adb push to transfer files, it works, but isn't the fastest. Right now I have everything setup for the bigger partitions and am working on a newer kernel to fix selinux problems so we can maybe get omni lollipop going. If you care to do the repartitioning, I believe the twrp version in it works better with mtp, but that will wipe your device first.
[Eee Pad Transformer Android Development] Garrafone:
Im having a issue for fist time , im on 2.6.3.10 and katkiss #11 and im trying to update to #17.

I have put the zip as usual, make the wipes and when im try to flash i get

E: unable to mount /external1

E: unable to mount /external2

E: unable to mount /external3

E: unable to open zip file

I try to update to Twrp last version 2.8.11 but i get the same issue with the zip, i get that error, i have done wipe of everything and get the same :confused:

I get on mount system cache data and sdcard tagged, im unable to tag external 1 2 and 3 :rolleyes:

Any help please?

Thank you very much

Solved, estupid problem, bad sd , try with another sd card and solved
[Eee Pad Transformer Android Development] grofweg:
Try the following: download the latest TWRP zip to your external SD card. Boot into TWRP. Go to advanced and use the file manager to move the TWRP zip-file to the internal storage. Try to install it from there. After installing, reboot device once more and flash rom and gapps.
[Eee Pad Transformer Android Development] Garrafone:
Thank you! Yes, the issue was on the SD card, people with this problem can put the zips on another sd card and try again from recovery and should work!

It seems to be some kind of file corruption at the SD media
[Eee Pad Transformer Android Development] allard1997:
Is there a chance that this TWRP will be updated to 2.8.4.0?
[Eee Pad Transformer Android Development] DROITURK182:
+1

Sent from my HTC Space Banana
[Eee Pad Transformer Android Development] sidneyk:
Yes, and with some luck, a new kernel to boot - to use a pun.
[Eee Pad Transformer Android Development] Guichinga:
Hi Sidneyk,

I copy over from Timduru's thread some issues we do have since the last version when trying to restore update.zip. Maybe you have an idea what is wrong with TWRP and the restore option of the Titanimum Backup update.zip file.

I have exactly the same issue since TWRP 2.8.1.1 but I wasn't able to find a solution until now.
[Eee Pad Transformer Android Development] sidneyk:
I believe it's covered somewhere in this thread. It's a titanium issue, not twrp. They were using an older updater binary where newer twrp uses a newer binary, I believe.
[Eee Pad Transformer Android Development] Guichinga:
I saw that post already, but the same is working under 2.8.4.x on all my other devices without any issue.

Only on the TF101 I have that issue.
[Eee Pad Transformer Android Development] doppelhelix:
Open the zip and replace META-INF/com/google/android/update-binary with the binary found in your rom.zip.
[Eee Pad Transformer Android Development] sidneyk:
Actually, twrp only runs whatever updater binary is supplied, but my builds don't recognize some of the older binary commands.
[Eee Pad Transformer Android Development] Skyen:
I have problems too.

Tried install 2.8.1.1 from 2.3.2.3 recovery. Reboot to system fine. But when booting to recovery nothing happens after the volume up press. Stays with the Eee Pad logo, and text "Booting recovery kernel image".

I can still boot android, and reinstall 2.3.2.3 from blob file.

I tried several downloads, both on internal and sd. (When im flashing with check MD5 to on, it always fails. But checked MD5 through apps and is ok.)

I have no idea what version my TF101 is. The serial nr label is gone.

Edit:

I tried older versions 2.8.0.0 and 2.7.1.5 that are found under all downloads on the download link provided in post 1. Same problem. So i have to stay with 2.3.2.3 and kitkat.
[Eee Pad Transformer Android Development] sidneyk:
I don't really know what to tell you here. I've tested and used 2.8.1.1 on 2 different SBK1 TF101's with no problems. I haven't tested either of the TF101G or the SL101 versions or on other revisons of TF101 as I don't own these devices. If you're trying to use the TF101 versions on an actual TF101 (NOT tf101g or sl101) and having problems and you've downloaded the correct files, then it has to be either something awry with your downloaded files, the flashing or your device. Works fine for me.
[Eee Pad Transformer Android Development] Sni:
2.8.1.1 does not completely works for me (while 2.3.2.3 works good)

I got black screen after booting twrp. However MTP and ADB works.

Looks like something wrong with backlighting.

Lights flicking sometimes after button click, but turns off immediately.
[Eee Pad Transformer Android Development] sidneyk:
I'm going to retest in a bit with my wife's tf101 by downloading both the zip and md5 files and putting them on the external card and flashing. I'll let you know how it goes. That version has kernel based off timduru's kernel.
[Eee Pad Transformer Android Development] sidneyk:
Just downloaded and reflashed 2.8.1.1 on another sbk1 tf101 without issue. Might be something with your hardware or bad flash or download. Make sure to boot to android after flashing before trying it out.
[Eee Pad Transformer Android Development] Sni:
thanks for the tip!

I really have harware problem - my backlights turns off on high birghtness...
[Eee Pad Transformer Android Development] erikive:
I have the same issue coming from 2.5.0.0, is there a blob file for the 2.8.1.1?
[Eee Pad Transformer Android Development] sidneyk:
Yeah, just unzip the downloaded file, the blob is right there, ready to dd.
[Eee Pad Transformer Android Development] gdlin:
Hi, I have a TF101, with timduru's KitKat. I flashed with TWRP the new zip file, and then also tried with the "dd" method, but I still get the same behaviuor. When I enter into recovery, a few seconds after, the device's screen turns black and it seems to hang there, and I have to reboot it. The ammount of seconds it's not fixed, sometimes is 1 seconds, other times I can browse trough the menus. I've tried flashing from the internal and external memory.

Any suggestions ?
[Eee Pad Transformer Android Development] Harley:
hello, I installed on my tf101 TWRP 2.8.1.1, but the touchscrenn not working.

how do I fix? thanks
[Eee Pad Transformer Android Development] grofweg:
You could try to flash the 2.6 versions first reboot and then flash 2.8. You can find a link of Josteink's version here; http://nexfiles.kjonigsen.net/tf101/twrp/
[Eee Pad Transformer Android Development] Magissia:
Hello, are there plans to release a new version with inverted storage ? Or is the last version able to detect if the storage was inverted dynamically ?

[Eee Pad Transformer Android Development] sidneyk:
Not planning any updates at the moment. In trying to get newer kernel working discovered that what I thought was working wasn't, concerning selinux.
[Eee Pad Transformer Android Development] gdlin:
Hi [MENTION=4342873]sidneyk[/MENTION]

I'm also having the problem that after the update, the tablet reboots soon after entering the recovery. The thing is that now I can't use ANY TWRP version. I tried everything. I restored the original ASUS firmware using EasyFlash and NVFlash, and I also even tried flashing your image, that makes the partitions bigger, but as soon as I enter into recovery mode, the tablet reboots itself. I was thinking that the internal memory MUST had a problem, but if I flash CWM 5.5 or 5.8 it works. I've used it to flash KatKiss 4.4 without problems.

Any ideas??

Thanks
[Eee Pad Transformer Android Development] JJeng:
Hi all,

I'm having an issue booting to TWRP

Goal: Trying to install KatKiss ROM - Asus TF101 Lollipop 5.1.1 Release 30

Issue: Stuck on trying to update TWRP to 2.8.1.1

Symptoms: TWRP 2.8.1.1 does not start, Stuck at "Booting Recovery Kernel Image",

What was done: I don't remember when I rooted, but i rooted from stock. Started out using Rom Manager. Decided Rom Manager wasn't going to work after Clockwork Mod 6.0.1.3 failed to mount the SD Card... or do anything. Used TWRP Manager app to load TWRP 2.3.2.3. Flashed CM 9.1 image that Rom Manager downloaded. attempted to update to TWRP 2.8.1.1 listed in OP as per KatKiss Installation instructions. This displayed the symptoms as described above. adb pushed the blob in the zip and executed dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4 . This resulted in the boot screen with the blue progress bar, but I ended with the same symptoms. Then I used the dd method to load Josteink's build from the link grofweg provided in the above post. This loaded TWRP 2.6.0.0

Currently loaded: CM 9.1

Current recovery: TWRP 2.6.0.0 from Josteink's link a few posts above (using dd method)

TF101 SN:B40 so... SBK1?

Other utilities used:

Universal_Naked_Driver_0.72

EasyFlasher-0.8.3b-STABLE_TWRP2.6.3.0

Not sure what to try next, any suggestions?

Thank you,

JJeng
[Eee Pad Transformer Android Development] dbuckham:
Have you tried re-downloading 2.8.1.1. You could have a bad file.

Next question...why use ROM Manager? If I remember the last update to TWRP, I used TWRP to update it. Just flash the file like any other.
[Eee Pad Transformer Android Development] doppelhelix:
ROM Manager is the worst. Hard bricked my Gio back in the gingerbread days. Besides, it's abandoned. Last update was over 2 years ago.

It's just as useful as this
[Eee Pad Transformer Android Development] nbowman:
I keep consistently having issues with this recovery. Every version of twrp past 2.7 will just boot into a black screen, with a flash of the recovery screen if I press a button. I've looked through the thread and other people have had this issue with no solution. Any help here would be greatly appreciated.

How can I install trwp 2.8.1.1 in transformar tf101 from zip file?

I'm sorry but y don't know How I can install trwp 2.8.1.1 in asus transformer tf101 from zip file.
[Eee Pad Transformer Android Development] doppelhelix:
Do you already have a custom recovery on your device? Is the device rooted?
[Eee Pad Transformer Android Development] albert223:
Yes, twrp 2.3.2.3
[Eee Pad Transformer Android Development] doppelhelix:
OK. Just flash the zip with TWRP like any other flashable zip and reboot

Important: let the device reboot completely, before booting the new TWRP.
[Eee Pad Transformer Android Development] RomanSixty:
I have the same problem (installing 2.8.1 using 2.3.2.3). However when I do so I can't get into recovery afterwards. The device just hangs and I have to reinstall 2.3.2.3 from TWRP Manager afterwards to get a working recovery.

Two things may be related to that:

1) TWRP (2.3.2.3) won't mount my external SD card. The source device is missing from /etc/fstab, so I have to manually mount it using terminal commands.

2) After it's mounted I can't install the 2.8.1 ZIP using MD5 checks. Again in terminal mode I can check myself (md5sum *.zip) to see it's actually the correct checksum. But still TWRP complains about it not being right. When I install without MD5 checks, I get the result mentioned above (no working recovery).

Any ideas what I could try now?
[Eee Pad Transformer Android Development] RomanSixty:
Okay, I got around that. It seems TWRP expects the external SD to be it the microSD in the tablet itself, not the actual SD slot in the keyboard dock. So mounting works now.

However I'm still stuck with 2) and getting to work 2.8.1.
[Eee Pad Transformer Android Development] doppelhelix:
Try this:

Make sure you have the right recovery.zip

Extract twrp.blob from the zip to the root of your sdcard. Open terminal and type

su
dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4
exit

Reboot the device completely till you are back in the lockscreen. While rebooting, there must be a blue/green progress-bar, indicating that the recovery is installing.

Now reboot into the new recovery

If no progress-bar was visible, open the terminal again and type

su
dd if=/dev/zero of=/dev/block/mmcblk0p3
dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4
exit

Reboot again and see the progerss bar.

Now you can boot into the new recovery.
[Eee Pad Transformer Android Development] RomanSixty:
Thanks for the reply. I tried that but to no avail. The progress bar appears, I boot until I see the lock screen and reboot then. Now when I try to enter recovery all I get is:

Android WW_epad-user bootloader < e> released by "WW_epad-9.2.1.27-20120615".
Checking for android ota recovery

Checking for RCK.. press key <VOL_UP> in 5 sec to enter RCK

Booting recovery kernel image

And that's it. I tried leaving this screen for quite a while but even after a few minutes nothing changes.
[Eee Pad Transformer Android Development] doppelhelix:
Which device do you have? tf101/tf101g/sl101). Did you download the correct version from the op?
[Eee Pad Transformer Android Development] RomanSixty:
I have a TF101 and downloaded the corresponding version.

The latest version I got running was 2.6.0.0 from josteink (the ZIP file from here). However that version apparently still isn't sufficient to install the latest KatKiss releases.
[Eee Pad Transformer Android Development] Piehti:
You may want to install that one again then and from there a flashable twrp 2.8.x zip?

Else there is a tutorial on my blog about flashing a recovery to the TF101.
[Eee Pad Transformer Android Development] RomanSixty:
I also tried installing 2.8.1.1 via 2.6.0.0 but the result was the same.
[Eee Pad Transformer Android Development] Piehti:
Maybe you have to go back some steps – as annoying as I could be. Do you have a NAND / CM backup or anything like that? Something, that was created before this started out? Go back to there then. If not:

Reflash a stock ROM (or at least Timdurus KK 4.4.2, then 4.4.4 ROM (I'd start at the very beginning: stock ROM! – might save you another rollback...) From there go EXACTLY as told in any tutorial. A lot of ROMs have some dpendencies on files and stuff. Maybe you lost some of that on the way.

I got the strange feeling, that you might have corrupted some flashes on the device, which are not obviously to be seen. Maybe reflashing all possible flashes from the scratch might help.

There are many people how (accidently) destroy parts of flash memories while flashing theire phones / tablets. I know a lot of Wiko Rainbow users who suffer from NVRAM-errors and lost IMEIs.

Wish you luck! :/
[Eee Pad Transformer Android Development] RomanSixty:
Alright, I didn't suspect the installed ROM would have an effect on the function of the recovery tool. But indeed that did the trick. I installed KatKiss 4.2.2 using TWRP 2.6.0.0 (I had to google for the ZIPs since those linked here in the forums are already 404ed). Afterwards I finally could install TWRP 2.8.1.1 without further problems. Thanks.

TWRP 2.8 doesn't work and neither does your solution

Hi,

So when I flash twrp 2.8.xx form twrp 2.2.1, it says it was successful but it never goes to recovery, it locks. I tried to put those two lines of code in when in su they also seemed to work in the terminal but noting happened. I really want to get twrp 2.8 on my tf101! How can I do it?

thanks

---------- Post added at 09:52 PM ---------- Previous post was at 08:58 PM ----------

So you just flashed KatKiss 4.2.2 from twrp 2.6 and then went to recovery and flashed twrp 2.8 and it worked? I tried flashing twrp 2.8 from 2.6 but it got locked on the booting screen!

---------- Post added at 10:23 PM ---------- Previous post was at 09:52 PM ----------

This didn't work for me! When it gets stuck, I have to flash an older twrp 2.2.x version! I actually had to go back to stock rom!

So, I still can't flash twrp 2.8.x to get katkiss! Can you help with that?

Thanks

Hello guys! I need your help. I have tf101 with broken touchscreen.:( However, I can still use it with my dock.:cyclops: So, I have laptop-experience. Please, tell me, am I able to install KatKis 5.1.1 firmware using touchpad in TWRP, or it is not supported. If no, could you please tell me, how to install it without touch?:confused:

Wow, you are right. Just like you, I installed KatKiss 4.2.2 using TWRP 2.6.0.0 and then afterwards I finally could install TWRP 2.8.1.1 without further problems. Thanks for the tip!
[Eee Pad Transformer Android Development] chorra:
hi guys , throw me a hand please

I have one Memo Pad FHD 10, It is the same as the TF100? I would like to install TWRP, rom is in stock and Root.

someone could help me install TWRP on my tablet? I am a complete noob hehe.
[Eee Pad Transformer Android Development] Aloupha:
Disregard Please
[Eee Pad Transformer Android Development] lesebas:
Hello same request as chorra, could explain me how to install this version of twrp from a stock ROM with rooted device?
[Eee Pad Transformer Android Development] doppelhelix:
No. It's a completely different device. And a very exotic one. There's no xda forum for this device. You can search google for a german forum that achieved root. But no custom recovery and no custom ROM.

Assuming that you are indeed talking about the tf101 and it's already rooted, try this:

Make sure you have the right recovery.zip

Extract twrp.blob from the zip to the root of your sdcard. Open terminal and type

su
dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4
exit

Reboot the device completely till you are back in the lockscreen. While rebooting, there must be a blue/green progress-bar, indicating that the recovery is installing.

Now reboot into the new recovery

If no progress-bar was visible, open the terminal again and type

su
dd if=/dev/zero of=/dev/block/mmcblk0p3
dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4
exit

Reboot again and see the progerss bar.

Now you can boot into the new recovery.
[Eee Pad Transformer Android Development] lesebas:
Yes it is a TF101.

When you say ''type in terminal'', it is from adb console on my PC or do I have to install third party application to get the terminal on my TF101?
