same problem

hey, i have the same problem, i have not fixed it yet sorry. if you figure out how, can you message me?

---------- Post added at 04:30 AM ---------- Previous post was at 04:25 AM ----------

i dont think so. i am not really sure how that would work though because i cant seem to find any extension or the file being an extension. or am i looking at it in the wrong way?

---------- Post added at 04:51 AM ---------- Previous post was at 04:30 AM ----------

While i was reading though some of the past replies somewhere on page 11-15, i found out that the file has to be on the device, not an external memory like the sd card. well, im testing it now, and it seems to run perfectly. Ill update you guys if it worked on not.

EDIT:i was able to get it back to .17 and root it, and get it back to .29 without a problem. TYSVM Wolf

Hi there, post the output of this command ( in terminal ) ls -la /sdcard/

Excuse me, I forgott to mention that I have a Prime. >_<

Found a DE version on the internet anyways, sorry for the confusin
[Eee Pad Transformer General] billy197302:
Right im a complete novice, my prime is running .21 and is painful slow! So i unlocked the boot loader hoping this would allow me to install a custom rom. But now i cant as i need root. So how can i downgrade and gain root and then start over again? Will this one click method work for me?

Please help

just curious will method 2 or 3 work on the latest update for tf101 9.2.1.24
[Eee Pad Transformer General] phigafr:
hello,

is it possible to go deeper in details for Method 3?

1. Upload the RECOVERYBLOB file to internal storage of your tab. (mounted as /sdcard) (don't have any file as such)

2. Connect tablet to the computer and start ADB shell session.

What is "ADB shell session"?
[Eee Pad Transformer General] Thing O Doom:
type in a folder where you have adb.

adb shell

Then its started
[Eee Pad Transformer General] phigafr:
well, no devices detected...but I can browse it

will wait an apk to root my TF201 later on..
[Eee Pad Transformer General] DONNY TRUMP:
I got it working with method 3 on my .24 I was having trouble at first with the last "dd" command aka step #5 but then I figured out that I had to put the recoveryblob on the root of the phone memory and not the actual physical microsd card...which was my mistake as I misread the instructions. after I figured that out everything was a breeze.

---------- Post added at 10:46 PM ---------- Previous post was at 10:44 PM ----------

Well if you can browse it then you should be able to detect it, but reading your earlier post, should we assume you're not familiar with ADB? Just youtube it, im sure there are a few videos on how to get ADB working.
[Eee Pad Transformer General] idcrisis:
It may be better to use a tool to automate Method 3:

http://xdaforums.com/showthread.php?p=26918790

Safer if you ask me, no adb shell session first time use to do a naked dd to a recovery partition manually
[Eee Pad Transformer General] Jive Turkey:
A few people have commented that the TF101 and TF101G use the same blob. However, they have different firmwares, so I'm wondering if someone could explain why the blob is the same? It doesn't make sense to me :confused:
[Eee Pad Transformer General] skarfreak:
so great...

if only i have the courage to do this... i wish i cud send my Prime to anyone to downgrade and root it, then install ROM to it...
[Eee Pad Transformer General] jdineshk:
wow. this is amazing
[Eee Pad Transformer General] Ghisy:
I'm currently using Roach's Prime 2.1.1 ROM (HC) and I would like to try Revolver 4 (ICS) but I'm afraid I might not like it (performance-wise). Do I need to use method #1 if I wanna downgrade or can I just restore a nandroid backup of HC? Thanks!
[Eee Pad Transformer General] Thing O Doom:
You can Full-wipe and nandroid back if you have recovery.
[Eee Pad Transformer General] pkfox:
Hi there, congratulations on finding this workaround, its so obvious now that you've shown us how. The Holy Grail now must be to find a way of achieving this without adb or using a PC, once again very good effort.
[Eee Pad Transformer General] SUPERGAMERVN:
Thanks about this :x
[Eee Pad Transformer General] Ghisy:
Thanks! Does a full wipe also wipe the internal sd card on the TF101?

I've been searching around - has there been any development on getting the 201 on .21 rooted without using the ASUS bootloader?
[Eee Pad Transformer General] collinsac24:
This is what the thread is about....
[Eee Pad Transformer General] tranducnam:
2 month ago, i've rooted Asus TF201 and then updated ota to 9.4.2.21, by that way, i losted the root. i've tried to root FW 9.4.2.21 but it's not working. I want to follow your downgrade guide but i'm worry that i rooted and updated my Asus, and now if i downgraded FW to 9.4.2.15 and rooted again, would my Asus be dead?! please help me, thanks so muchhhhhhhhhh
[Eee Pad Transformer General] sparkym3:
There is a new root method that does not require downgrading, I don't have the link but it is in the TF301 threads. You better hurry though, with the update that will be released later this week that method and this one may no longer work.

Don't forget OTA rootkeeper to save your root.
[Eee Pad Transformer General] Thing O Doom:
if u use the superwipe script it does :D

so,

i am having issues after getting into shell.. wanting to restore back to stock...

[Eee Pad Transformer General] pkfox:
I have used this method dozens of times and it works perfectly, you MUST REBOOT after the mv /data/local/tmp /data/local/ tmp.bak and ln -s /dev/block/ mmcblk0p4 /data/local/tmp commands
[Eee Pad Transformer General] CMiles1979:
Strange, everything went good, went to .15, so my prime was rooted, downloaded latest firmwire and see that it is 9.4.2.28 and now my prime isn't rooted anymore. Is this easy to fix. Need rood for vnc server.
[Eee Pad Transformer General] pkfox:
All you need to do is do option 3 again to install CWM again then flash the root package again.

Method #3

I have successfully downgraded and rooted my Asus Slider with this method.

Thanks a million...you're absolutely a genius!!! :)
[Eee Pad Transformer General] kraju1:
Thank you very much

Thanks man, you're great!!! I was looking for an answer how to fix my tf for few months and i almost send it to the ASUS to fix it. It worked for me on TF101G with bootloop and without recovery :eek: Thank you very much ;)
[Eee Pad Transformer General] vc_stargazer:
hey thanks for the guide....i got a problem

when i tried to factory reset my transformer from setting, my sdcard(internal) is left unformated

and when i tried to factory reset via cwm, it says "Error mounting /sdcard/.android-secure!"

u guys encounter this issue?what's the solution?
[Eee Pad Transformer General] vc_stargazer:
thanks btw
[Eee Pad Transformer General] huub99:
You are the greatest

Short story

bought a TF300T

rooted without downgrading

removed some asus apps with titanium

reset settings

upgrade to .30 fails, both ota and manual

probable cause "removal of the apps"

used this method to uograde to .30

and it works!! Many thanks
[Eee Pad Transformer General] freak666999:
Very Good Work!

I downgrade from .21 to 15 but i cant OTA so i do the same steps to update my TFP so i get the OTA :D

I rolled back to honeycomb 8.2.2.6 and I think I flashed the unrooted WW version instead of US. Anyone know how to get back to new stock version .27?
[Eee Pad Transformer General] kjacksonmusic:
Hey guys trying do anything I can here to get a new recovery flashed on my tab, tried Method 3 Listed in the OP and I can start an adb shell it gives me an error message as follows "- exec '/system/bin/sh' failed: no such file or directory (2)-) This same error message appears when i try to run PERI as well.

To give you bkg on my issue I flashed a alpha rom to check it out, then when i tried to boot into recovery I couldn't (it showed the default one) I cant choose to wipe data or boot into android because my Vol up button is physically broken. So I was stuck in a bootloop I ran PERI it stopped the boot loop but couldn't do anything else as it just gave me that error message.

I am without a data connection or any connection really other than adb. I can open rom manager and press reboot to recovery but this does nothing, as it shows no recovery is flashed if i try to press flash recovery it of course states i need an internet connection.

Thanks for your help.
[Eee Pad Transformer General] qwertylesh:
(Regarding Prime/TF201 )

I thanked your OP months ago, finally got angry enough with how BAD .28 has been to flash back down to .15 with your instructions.

Which BLOB for TF300T?

Hi:

I've been reading around and I found that some of the BLOBs you posted can be used for TF300T, could you please tell me which one?

Thanks in advance

[Eee Pad Transformer General] Moothead2:
Nevermind, I put a '/' after blob.
[Eee Pad Transformer General] Pretoriano80:
Hi guys,

Do you known if these methods will also work on Asus Transformer Infinity (tf700)?
[Eee Pad Transformer General] sparkym3:
It should since the root method that uses this form of linking to get access to the partition still works. You will have to get the blob though, as it is not provided in the OP.
[Eee Pad Transformer General] Pretoriano80:
Thx mate, just wanted to be sure is working on Infinity so we can create a "how to" guide in the tf700 thread. As for the blobs yes, will provide the correct ones.
[Eee Pad Transformer General] rickc3k:
Thanks so much for this, like the person above, I got the chinese version of the tablet because I am currently living in China. It felt completely useless without the Google services, now I am finally happy with it. I was afraid to brick it or something, but it was simple enough.
[Eee Pad Transformer General] paedz718:
I had a bad upgrade to JB, all my Gapps force close as soon as I get to the JB Welcome setup screen and I can't get to the desktop. I believe the boot loader is updated when upgrading to JB so I am wondering if I can use Wolf's method (I have a locked BL) to flash back to .30/ICS firmware w/ no issues. Don't want to brick it and want to keep my warranty for the time being. Thanks for any help. This method seems pretty straightforward
[Eee Pad Transformer General] pkfox:
Give it a shot ' you can't do any damage if you follow the instructions carefully. Regarding your Gapps problem did you do a complete wipe before flashing the ROM and Gapps ?
[Eee Pad Transformer General] vipy:
please help

Hello please help a noob,

during the dd process i had a system failure.

It results in a broken device. It just stays on boot screen, locked.

Can get to standard recovery, but i was not able to flash a rom palced on the external sd as expected after reading around about how to do it.

Adb shows no device at all.

I also reinstalled windows transformer usb drivers but without result.

Pleas can suggest a method to have back adb or perform the restore by the recovery.

Thank you

Very inexperienced user here...I downgraded to Honeycomb using Method 3 and the WW 8.6.6.23 BLOB. It's worked out great since ICS was killing my device. Now I'm hearing Jelly Bean OTA may be coming but after Method 2 (without rooting) I understand that I'm no longer on the OTA path. Can someone help me with how to get back on OTA? I've tried searching the forums with no luck thus far. Thanks

TF201 JB downgrade

I somehow managed to lose su after updating to JB (locked with OTA update). I want root back and was considering downgrading to .21

Does anyone know of any additional risks & chances of success?
[Eee Pad Transformer General] ogg1e:
which blob version (.21, .28 etc) do you use? Is it the one of the firmware you are on, or the one of the firmware you wish to downgrade to?
[Eee Pad Transformer General] xmun:
I'm not sure what you mean. I am currently on build JRO03C.WW_epad-10.5.2.15-20120917. I though of downgrading to any version that would allow me to root the tablet then upgrade again.

[Eee Pad Transformer General] Grady:
Xmun,

Any luck? I am in the same exact boat. I updated to JB (without thinking to backup root) and lost it. I was thinking of a way to get back to ICS, so I could root again, save it, and then update to JB.
[Eee Pad Transformer General] moisaal:
Is it possible to use Wolf's method to downgrade A rooted tf300t running Jellybean to good ol' ICS ?
[Eee Pad Transformer General] mrfleetwood:
Well, I had the backup for root, but lost it anyway after manual update (automatic update failed, maybe because of the root?). SuperSU is still there, but cannot recover root :(
[Eee Pad Transformer General] ogg1e:
I get the same error as well.
[Eee Pad Transformer General] chleoj:
Did you execute the commands after typing " adb shell"? (without quotes)
[Eee Pad Transformer General] xmun:
Yeah, either adb shell or with terminal emulator off the device itself.
[Eee Pad Transformer General] chleoj:
after typing adb shell, you should get "#" sign, not $ sign. If not, try to type "su" to have root or admin rights and able to write on system files.
[Eee Pad Transformer General] klarmacker:
i only get $ and no # after adb shell...

i dont have su...

so when you are on jelly bean you have to wait ofr a bedder way?
[Eee Pad Transformer General] panthrosrevenge:
I am also interested if using this method is a viable way of downgrading OTA jelly bean back to ICS to recover root access that wasn't backed up
[Eee Pad Transformer General] ScriptJunkie:
does not work for going from jb to ics

I had to get rid of root to send it to RMA and it got updated without back up. So i'm stuck without root. And I tried this method but a permission denied message pops up on adb and terminal app. Turns out Asus has closed this exploit. Some people in this post get the same results (read the 2 previous pages). And I have been reading around and there is not a way to root in jelly bean if you have the bootloader locked. If you are willing to unlock use the search bar to find a method.

Otherwise, u are like me, waiting for the pros to get into the case. But it is unlikely this is going to happen soon. Many dev got feed up with noobs like us *****ing about root exploits for .21, and Asus looking up the forums to close this exploits on the next update. So they don't want to work out solutions again and again, and even if they find any, they may keep it to themselves so the exploits are not closed by Asus.

I hope this helps. If you really need root soon, your best bet is to unlock.

TF300T JB

Does this method work if my TF300T is already on JB?? I already unlocked it btw, if that info makes the difference =/
[Eee Pad Transformer General] socngill:
Hi. Looks like a promising way of regaining root.

I have a Prime. The bootloader is unlocked but I lost root access on update to JB. I've tried various ways of getting root from a part root but none of them work.

Do you think this should work for me? Any risk to my Prime if I give it a go???

Thanks in advance.

Hi, there

I have a TF700T and stupidly did the update to 9.4.5.30. And now I'm stuck with a version that can not use nvflash. I know I have to go back to version 9.4.5.26 or below in order to use nvflash. My TF700T only have root and do not have the bootloader unlocked. To get there I need your help.

With this process can downgrade to 9.4.5.26?

I can do the commands directly into the terminal, or necessarily have to be with the pc?

RMAed to stock jb

Hi. I had to RMA my (re-un)rooted ICS TF201 because of a display problem. What I received was my repaired TF201 upgraded from ICS 9.4.2.x-de (german firmware still is on ICS) to WorldWide JB. Now I'm stuck to JB ....

Using the ASUS unlock tool I only receive the well known "network error" message so it seems I can't root my TF that easy again. I maybe have to RMA it once more to let them unlock my TF which (for what I've read) costs me about 100 Euro + transport.

Any tips for me? :D
[Eee Pad Transformer General] bads3ctor:
They changed perms on /data/local in Jelly Bean so you can't rename tmp. Doesn't matter anyway because I got write access to /data on my TF300 locked Jelly Bean using this: http://xdaforums.com/showpost.php?p=35243317&postcount=3

and then I could do this:

mv /data/local /data/local.bak

mkdir local

ln -s /dev/block/mmcblk0p1 /data/local/tmp

All good! Except upon reboot, then I try this: http://xdaforums.com/showthread.php?t=1704209

to gain root but have no luck so far. This service should be running as root on device bootup and by creating /data/data/com.asus.LogTool/files/logdog-conf.sh and adding commands to remount /system rw and write su to /system/bin, I should be able to root the TF300....BUT....it does not work.
