OMG you saved my transformer!!!

Long story short, my tablet, as of 20mins ago, was in such an awkward status:

- has su and superuser.apk in /system/xbin

- all root checker apps say I'm NOT rooted

- on stock recovery but stock images put on external SD card won't get recognized

- whenever an app requests root, it got automatically denied by SuperUser.

and I saw this post....I'm back on 9.2.17 stock now!!:D

Thanks a million! ln -s...genius!!
[Eee Pad Transformer General] Thing O Doom:
Nice exploit! I knew there was a way!
[Eee Pad Transformer General] kevchaps:
Did you start off with 9.2.1.21? Or just fixing your botched 9.2.1.17?
[Eee Pad Transformer General] alvin612:
9.2.1.21.

I messed up the rooting and recovery after ota from .17 to .21
[Eee Pad Transformer General] hearts king101:
You are genius wolf

:D:D:D:D:D:D:D:D:D

It worked :eek:. Yes Yes Yes Yes Yes

THANK YOU SO MUCH WOLF​

FYI: I copied 3 files named ( EP101_SDUPDATE, EP101-SDUPDATE, EP101SDUPDATE ) so i don't know which one worked bcuz i tried the 1st name yesterday but didn't work :confused:.
[Eee Pad Transformer General] kevchaps:
Great that it worked for you.

When I get a new data cable, i think I will be headed back to honeycomb.
[Eee Pad Transformer General] warlord234:
Sorry for asking! but Is 'rooted method 1' give any benefit over using CWM to flash stock ROM?
[Eee Pad Transformer General] wolf849:
Nope, I described it to show the differences between rooted and unrooted methods ;)
[Eee Pad Transformer General] Rodriger:
Sorry for asking. If I use this method on my tf101 to roll back to HC will it solve reboot and SoD problems?
[Eee Pad Transformer General] steven178s:
Im trying method 2 and it wont let me adb shell after reboot.
[Eee Pad Transformer General] wolf849:
It should, that depends whether you had such issues on HC. If you did not than by downgrading you should get rid of them.

After 1st reboot? Maybe give it a try after full bootup.
[Eee Pad Transformer General] Rodriger:
Should I try it if flashing stock HC by CWM didn't helped solve reboots and SoDs?
[Eee Pad Transformer General] msl400:
Thank you very much, i'm back on 8.6.6.23 from 9.2.2.23. The only thing i had, after the flashing Android want not boot. I made a wipe and everything is ok.

Thank you again.
[Eee Pad Transformer General] Shinare:
I have a Transformer Prime, I downgraded to .15, rooted, installed voodoo root keeper. Backed-up root, temp-unrooted, went to settings>About Tablet>System Firmware Update and its telling me "Failed to connect to internet. Please check your internet connection."

My internet connection is fine, I'm able to get out via browser and even got into Play Store to get voodoo root keeper. Not sure why its doing that. Anyone got an idea?

Edit: Realized I had droid wall (firewall) installed when I first got this tablet because I had t on my phone which was rooted. I uninstalled it thinking that was the problem, and now nothing can get out to the internet. :( any ideas?

Edit 2: Rebooted now other things can get out to internet but still getting same message from System Firmware Update. :confused:
[Eee Pad Transformer General] Archangel:
plus one on this now that Asus released the firmware??
[Eee Pad Transformer General] Lakitu7:
I'm a little confused. If I flash a blob via methods 1 or 2, does it touch recovery or kernel at all?

I have rooted .17 with a custom kernel and I am wondering if I could use this to get to rooted .21 with a custom kernel, after extracting the .21 blob from dlcdnet.asus.com/pub/ASUS/EeePAD/TF101/US_epaduser9_2_1_21UpdateLauncher.zip
[Eee Pad Transformer General] maatsby:
That's probably the problem

I think you have to have the same region as you originally had to receive the ota
[Eee Pad Transformer General] slixzen:
Well, I was originally on a .21 US, flashed a .15 US and I am now receiving the "Failed to connect to the Internet. Please check your Internet connection" message.

I downgraded my tablet to .15 successfully, and I also have root. I went to back up my root with VooDoo's OTA app. So now, when I attempt to do a OTA system update, it says I have no internet connection. However, if I open up the browser application, I can browse websites. If I power cycle the tablet, that doesn't seem to resolve the issue either.

While I am not saying this is the fix, try toggling or enabling USB Debugging Mode in the Developers options. I disabled mine after I was done rooting it. After I enabled it again, and checked for an update, it started working.
[Eee Pad Transformer General] Shinare:
Ok was able to get the update notification and downloaded the update. Told it to do it and it rebooted. Went to the android guy with the spinning wire mesh. Got about 25% on the progress bar and then the guy was on his back with a triangle and an exclamation point. Stayed there for a few minutes and the rebooted back to .15 saying there was an error and reverted. Downloaded the update a second time with the same result. Any idea? Do I need to do a factory wipe? I'd hate to loose everything but I'm willing if it will fix it.
[Eee Pad Transformer General] Archangel:
+1 got this and the update failed after downgrading and then rooting any way to fix?
[Eee Pad Transformer General] MrHassell:
just a thought..

Does it still boot? Do you have root?

Put the WW 9.4.2.11 blob on the sdcard, link to /dev/block/mmcblk0p4 as the instructions in the OP and allow it to restore, then use Voodoo OTA root keeper and ensure your SU and busybox work.
[Eee Pad Transformer General] Archangel:
I have the tf300 and yes it boots and everything is fine however, when I try to update to the .26 firmware it starts to do its thing then after about 25 percent it stops, the little android dude flips on his back and the red exclamation point appears. Then it reboots and says that the update failed? I have the blob on the root of the drive. I thought having it there might stop the update so I deleted it and still a no go?
[Eee Pad Transformer General] warlord234:
I'm using CWM to downgrade to HC and SOD is still happen.

Is this method gonna fix SOD?

Has anyone try and get positive effect?
[Eee Pad Transformer General] samuelson:
on method 3.

on step 5 i cant start another adb shell session untill the tablet gets to the lock screen, is that normal??

i then enter:dd if=/sdcard/recoveryblob of=/dev/block/mmcblk0p4

and this appears straight away:

8860+1 records in

8860+1 records out

4536396 bytes transferred in 1.718 secs (2640509 bytes/sec)

no 3-10 minute wait??

i then type exit then adb reboot and the tablet boots as normal?

really confused, been trying for the last 2 hours with no joy please help me:confused:
[Eee Pad Transformer General] mariox26:
Hi,one question.With this method can flash any rom i want?i make downgrade from .21 to .17 after i downgrade to 8.6.5.21 hc working fine,and i want to make sure if it working for another rom like android revolution hd 3.2.1
[Eee Pad Transformer General] e154037:
samuelson,

You may already have cwm recovery installed. Just boot you TF into recovery to check or to do next step in method 3 (flash superuser+su).
[Eee Pad Transformer General] Biofall:
Donwdgraded to .15 and rooted. Thanks so much man! I really didn't want to unnecessarily void my warranty.
[Eee Pad Transformer General] paul4haren:
Thank you!!!!

Some days ago .21 came OTA on my TF101, and - oohps - it unrooted my device.

After some googling I found this guide. It took me about 50 minutes to collect all files needed, and about five minits to unroot my device again following method 3.

It worked perfect!!!

Thank you for this guide!

Chalk up another one. Obtained .15 BLOB from a mirror in one of the responses in this thread. Down from .21 to .15 using option 2, used sparkyroot + rootkeeper, OTA took it back to .21 and root was restored perfectly.

Guys I did everything for method 2, and all went great until the point where I enter the command and wait 3-10 minutes for xxxxxx bytes. instead it just gave me a new command prompt line like it had previously and rebooted and now my Asus is stuck cycling in its boot cycle over and over. I can't even turn it off. This is my first endeavor into android and I just got it yesterday.

I was trying to downgrade to .17 from .21

Any ideas on how to fix this?

Just use the official firmware from Asus, flash it with cwm and you'll be unroot and stock recovery.

---------- Post added at 10:11 PM ---------- Previous post was at 10:03 PM ----------

This just means the move command failed because you don't have a /data/local/tmp dir. Is this the 2nd time you tried it? Anyway you can just skip that step since all it's doing is renaming your tmp directory which you don't have. Move on to the symlink (ln -s) step.

[Eee Pad Transformer General] Beermiester:
Thanks to Wolf!!!

This is soooooo awesome!

I had the "no serial" issue so when I manually upgraded from .15 to .21 and thus lost my root since Voodoo only works with OTAs.

RMA'd device to fix serial issue so I can OTA update. I had been debating unlocking device to install custom ROM. I'm so glad I didn't.

I've now gone from .21 down to .15 and am now rooted again!!!!

Thanks so much Wolf. :D

Edit to add:

I have since OTA updated back to .21 and have restored my root.

Need some help please.

Hello I have a TFP with a TW SKU and am wondering if I can use the .15 WW blob to downgrade my TFP root it then redo the OTA back to TW .21 . If that will not work does anyone know where I can download the TW .15 blob.

Thanks.
[Eee Pad Transformer General] Beermiester:
If you change the region you will no longer receive OTAs.

If you take the time to read through this thread I think you will find the TW blob you need. I do not feel like re-reading >20 pages for you to find what you need. But somewhere in this thread I saw a post from a guy (Russian) who's got them all available for download.

Reading is YOUR friend. Look and ye shall find.

[Eee Pad Transformer General] zAlbee:
This time you DO have the tmp directory. I guess it gets recreated whenever you reboot. So you will need to do the "mv" command before doing the symlink. (In other words, just follow the original instructions.)

Can you please explain where you started from?

You made a factory reset starting from stock .21 and then applied the method 3?

Thanks
[Eee Pad Transformer General] baseballfanz:
If all you want to do is go back to .17, use method 2.

If your goal is to root just use method 3.

To downlaod a blob, go to the OP, find the one you want and click on it to download.

I'm a total noob in this. I'm using mac Lion and installed android sdk with adb working (I think). I've downloaded the .11 firmware to the main storage of my prime and ready to go.

is there any way to get a Transformer prime 9.4.2.21 blob download in the US, i would love to downgrade and root so i dont have to void warranty. The links didnt work

thanks
[Eee Pad Transformer General] slopppy:
You shouldn't need the .21 blob for the prime. Downgrade to .15 with one of these blobs:

http://xdaforums.com/showpost.php?p=25489127&postcount=71

Then upgrade to .21 OTA (make sure you use OTA Root Keeper).

Unless I misunderstand?

Cheers,

Slopppy.

Edit: Maybe you just typo'd 9.4.2.21, when you meant .15? either way, maybe you hadn't seen that post I linked to with the extra mirrors :)
[Eee Pad Transformer General] npesa92:
downgrading

yes i did typo, my bad, i did mean .15, but this is a zip file correct? and so i could just root on .15 and then flash a rom that was made from .21 without actually updating through the tablet?

thanks

Edit: as well on step 2 how would i start the adb shell session with my android tablet, when i issue the first command 'mv /data/local/tmp /data/local/tmp.bak' how do i know tha tspeaking with the android device?
[Eee Pad Transformer General] slopppy:
Yep, that's a zip file. Unzip it, and unzip it again and you will have the blob file. That's the file you need.

This method gets you root ... it DOESN'T unlock the bootloader, which is what you need to flash another ROM.

Around page 5-10 ... maybe as high as 15 on this thread there is a script to do all the hard work for you. Just follow it.

Actually if you go a few pages back, there is an excellent guide by someone. I commented on how good it was ... just look for my post :D

Edit: It was freekers who wrote the guide, and here is the link - http://bit.ly/ICXrsw ... just follow that, it's very easy to follow.
