Great find!!

I can confirm it worked like a charm on my TF700 with JB 4.2.1 :laugh:

Thanks a lot!

Your zip file is broken.

Becides, there is no point, as SuperSU will update itself. (app from the market, binary fom the app itself)

Busybox can be updated using a Busybox app from the market.

Successfully rooted my TF201 (without unlocking).

Thanks a billion Morlok8k :good:

your welcome!

HI guys, this is really awesome. I have me301t and I want root. But is it really working right (I have JB 4.1.1)?? And when i root it, can I normally update to JB 4.2.1 when update comes to my region, or should i wait untill update comes and then root it??

THX ALOT AND SORRY FOR MY ENGLISH...

Root it now. Get Voodoo OTA rootkeeper. Backup your root!

(and if you somehow loose root, just run motochopper again after the update)

Can I unroot it back? Or flash back original firmware???

yep! you can unroot within SuperSU. (or any of the other unroot methods)

Sonofa.... figures. I finally take the plunge and unlock so I can root only to find out hours later someone FINALLY finds a way to root w/o unlock. Damn...someone should have shouted this from the rooftops (or all over the forums and IRC!)

Good job though and great find!

I posted this just a few hours after the motochopper exploit was released.
I didnt want to spam other threads or forums. and i dont use IRC.

new links work.
Although like i said, i really don't see the point.

in a month or two, they will just be outdated again and will need to be updated - but all that can be done on the tablet as part of regular maintenance...


Also, I don't like that you are including the PRO version of SuperSU. That is for people who have paid, and the developer has not released it for free elsewhere.
If people want to pirate it, that's their decision, but that can be easily be done after the tablet is rooted.
And since your version of SuperSU is hacked, would it get updates from the play store?

I used the tool but throughout it i kept getting a ADP is out of date error but it said it had rooted.

SuperSU is on but no busybox

what device (& version)?
what OS? Windows, Mac, Linux?

Is it just the SuperSU app, or did the su binary install?

Didn't work for me on TF 201

Hi,

i had a Root on ICS and Voodoo Keeper.. (Transformer Prime TF201, WIN 7 64 bit)
Still couldn't keep the root when it updatet to 4.1.1 (not on purpose)

tried severall methods including the partial root thing (cant mount system nor get su rights) and this one..

looked promising (no errors), since the ota voodoo keeper told me that it is now rooted but it still isn't (only option not checked is 'Root permission granted')..
also tried reseting the tablet an root again => still the same..

also can't make the SU Bin update (cause it's not rooted, no permission)

what to do? (shouldn't unlock bootloader since its not really mine..)

SU App installed and then i opened it and the binary installed.

TF700.

Windows 8 -

i've already used it in the past to root via debugfs method so it's weird i got ADP errors.

It worked like I said but after every step i got an ADP out of date error

ahh, you have a broken root if Voodoo say you are rooted.


there are instructions elsewhere that can help with that.

I had the same issue with my droid 4 when it got jellybean, but i was able to restore root using the chainsDD superuser app by clicking on OTA Survival.



your superuser backup is saved here:
/system/usr/we-need-root
and its called:
su-backup

in a terminal emulator do the following: (or something like it)

cd /system/usr/we-need-root
./su-backup
cp su-backup /system/xbin/su

well, then download the latest version of ADP and copy it into the motochopper folder.

or just install busybox manually... using the app on the market

thx for your reply, here's what i found out
"OTA Survival" => Superuser crashes

cp:
cp: can't create '/system/xbin/su': File exists

 

[bads3ctor]

thx for your reply, here's what i found out

cp:
cp: can't create '/system/xbin/su': File exists

Try this:
cd /system/usr/we-need-root
./su-backup
mount -o rw,remount /system
cp su-backup /system/xbin/su

 

[Morlok8k]

Try this:
cd /system/usr/we-need-root
./su-backup
mount -o rw,remount /system
cp su-backup /system/xbin/su

I forgot about remounting!

since he has a su file there, he should try this:

cd /system/usr/we-need-root
./su-backup
mount -o rw,remount /system
chattr -i /system/xbin/su
chmod 755 /system/xbin/su
chown 0:0 /system/xbin/su
chmod 6755 /system/xbin/su

if that doesnt work:

cd /system/usr/we-need-root
./su-backup
mount -o rw,remount /system
chattr -i /system/xbin/su
rm /system/xbin/su
cp su-backup /system/xbin/su

you may need to do this instead if the remount doesn't work:

busybox mount -o rw,remount /system

Question

This method is not working for me. I press enter and it says the deamon started successfully. but even after a few minutes nothing happens. If i lost root during an OTA will that cause problems because superuser is already installed or something like that?

 

[tryfrie]

Try this:
cd /system/usr/we-need-root
./su-backup
mount -o rw,remount /system
cp su-backup /system/xbin/su

thank you guys so much!
it worked.. so i got the partial root back (probably with ./su-backup) and could then mount the system to finally do this:
matthill.eu/mobile/root-transformer-prime-jellybean-update/

 

[penfold99]

Worked first time on latest official firmware, took just 15 seconds plus reboot time.

Thanks

awesome!
Glad you got it working again!

Broken roots can be a pain... OTA updates reset all the file permissions on the system files (including su) which is why your su file was there, but not accessible...

you probably have the same issue as tryfrie did.

did you back up your root? if so, follow the same instructions.

if not... let us know!

I did backup my root but I lost my superuser data after i rushed into something without reading and uninstalled super user because someone said they had success after uninstalling super user on their phone.and im afraid to do a factory reset because I have some apps frozen from before I lost root.


I am a n00b do I just open a command prompt and type those lines exactly? If I do that will i be able to just go to rootkeeper and restore?
