Hi, I am on TF101 .21 at the moment, rooted, custom kernel, OTA rootkeeper installed.
I wonder is that safe to update .24 using the official firmware update? Will I lost my root or custom kernel?
Or do I have to download the file on this page and flash it?

Download the file at the link. Since you are running a custom kernel I am going to assume you have a custom recovery installed which won't allow you to properly flash the OTA, and by that I mean it will just error out.
1-Use OTA rootkeeper to verify that root is saved
2-Update with .24
3-After upgrade, use OTA rootkeeper to restore root

He has a custom recovery therefore doing it this way will just result in failure, please just do it how I said, I did it that way and had no trouble what so ever.

Thanks, I downloaded from this link http://forum.xda-developers.com/show....php?t=1627301, no kernel version and I flash that zip file from CWM upgrade to .24.
I use rootkeeper to restore my root, everything works well. Thanks guys
That's what I did and it worked
Glad to hear OP, don't forget to chime in on the SOD/RR thread after a couple days and let us know how the new update is working for you.
So my tpt is rooted. can i get the ics update when its released??? Also when i check for updates it searches and returns nothing... not even the up to date message
The upgrade will download and be saved to your tablet. But it will only install if you have all the stock lenovo apps. I froze them with titanium backup, so I will have to thaw them to install the ics.
You should install and use the ota rootkeeper app to save your root. Of course the update won't be rooted, and we probably won't get it rooted because we don't have enough developer support.

i heard there was problems because of busybox
US versions need to install the 086 version of busybox, and the gps.conf file, and any of the missing lenovo apps. Use OTA Rootkeeper to temp unroot before and reroot after the update. I had problems, but it eventually worked for me.
You will lose CWR if you have it.
I had Google Play problems after the update and had to wipe.
It has been a long time since I have ever done an OTA update.
On most devices I'm typically running a custom ROM and do updates by flashing a new zip from a custom recovery.
I am currently running 4.2 that I got from here:
https://developers.google.com/android/nexus/images#nakasi
I flashed a custom recovery, flashed SuperSU via recovery, and installed BusyBox from the Play Store.
Now my Nexus 7 says it has an update.
Questions:
Will I be able to use OTA Rootkeeper and do this update?
Does OTA Rootkeeper also keep busybox?
Will I have to re-install my programs?
If there is an update to 4.2 why is 4.2 the latest thing I see on the google website I linked to above?

Root keeper should work fine since of is only a minor update.

Busybox won't be removed with an OTA update.

No, all your programs will still be there after the upgrade.

Google hasn't built the new factory images for 4.2.1 yet.

How is it that su gets removed during an OTA but not but not the busybox executables?
How are the busybox executables different?
Does an OTA explicitly go after su?
I have a notification for an android update as well. I'm rooted and unlocked, running stock. So, I just want to install an app from the market called root keeper before installing the update and all is well?
OTA rootkeeper is the app.
It worked for me, and app usage is fairly simple.
The SU app doesn't get removed, it's still there, it just doesn't have access, but OTA rootkeeper restores it.
I updated yesterday I think, the update mostly fixes that December issue, nothing major, it's a <1,5MB update.

Technically, what is going on here under the hood?
What do you mean by "doesn't have access"?
I don't fully understand how root works on Android between the binary su and the SuperSU Android app.
Does the OTA mess with setuid bits or something?
Does it lose access during the "Android is upgrading... Optimizing Apps" after it reboots?
I will do the update using OTA rootkeeper, right now I'm just trying to gain a higher understanding of what is going on.
Edit: Update successful. I have TWRP installed and this is what it looked like. Gave me a scare for a second.

I honestly don't know what is it that OTA rootkeeper does, I had doubts too. I'm not a developer of said app, so the questions you have should really be addressed towards the dev.
I know the feeling, I have TWRP too, and it gave me a mini heart attack
I'm glad everything worked out!

OTA rootkeeper makes a backup of the such binary and restores it after the upgrade. It works quite well, actually.

It does work well indeed. So basically, root access isn't lost, but OTA update removes the su apk, and rootkeeper restores it?
I don't understand how it can restore root without root access

I'm running a rooted stock nexus with twrp. I screwed up with the first 4.2 OTA and had to reroot with fastboot, supersu, etc. When this new one came up last night I installed OTA RootKeeper from the playstore and backed up su with it. I ran the update this morning and had root back in seconds with rootkeeper. Works well, just as described above. The googling involved in my last screwup saved some headaches this time.
Thanks to ALL on this forum.

It doesn't need root access to restore root because BusyBox remains installed. Basically what the app does to restore su is remount the system as read and write then use BusyBox to copy the su binary back to where it should be.

This is a link to the OTA Update for 12.15.15.
Download and install through stock recovery. Keep in mind if your missing any system apps or have them frozen this will not work.

After installation refer to this thread to root if you so choose.
