Title: JB 4.3
Post by: CBers on July 25, 2013, 04:39:17 PM: Anyone tried flashing their Nexus 7 (or 4 or 10) with JB 4.3 yet?

Images are already available, but it doesn't seem to be as straight forward as before.

This indicates a kernel that is "not stock", so I restored the stock kernel and tried the zip update again and had the same results. My next attempt was a sideload of the zip update file and I had the same error. I am looking at the stock rom 4.3 on xda Here (http://forum.xda-developers.com/showthread.php?t=2376881), but I am curious as to whether the OTA will give the same error, so until I receive feedback that the OTA fails for the same reason, I will wait a day or two before trying the xda 4.3 stock rom. Be advised, that the App Store version of SU has issues with 4.3, so make sure you read xda 4.3 stock rom post if you fail to access SU after applying the update with CWM.

This is the method that I used, trying option 1 and 2. I would be interested in hearing, if anyone achieves success.

Think I'll wait a few days before trying to update.

Yes unfreeze any apps that came pre-installed on your Nexus 7 and then install Voodoo OTA RootKeeper and run it to protect Root (just to be safe) and if you have CWM recovery, answer "NO" when asked on startup after the update, "do you want to replace your current recovery?" Answering yes will replace CWM with the stock recovery.

Post by: JayJ on July 26, 2013, 02:59:22 PM: Root is broken on 4.3 even with Chainfires updated SuperSU zip.
Anybody that flashes the OTA will need to re-root, Voodoo OTA RootKeeper does not work because of the security changes Google have made to Android in 4.3.

I've updated my Nexus 4 but not my Nexus 7.

Post by: CBers on July 26, 2013, 03:24:05 PM: Can't get my Nexus 10 into recovery mode (TWRP).

It boots and reboots just fine, but if I try manual recovery mode (power+volume down) it sits saying "Downloading - do not turn off target".

Will try again tomorrow via ADB sideload.

Post by: CBers on July 27, 2013, 12:20:00 AM: I can't get into TWRP so gonna try installing it via ADB, as GooManager can't do it as SUPERSU isn't available.

Unless there's another way.

Post by: CBers on July 27, 2013, 05:21:18 AM: Just did my Nexus 10 using WugFresh toolkit (http://forum.xda-developers.com/showthread.php?t=1766475).

Manually downloaded TWRP (v2.6.0.0) & SuperSU v1.43 zip.

Changed Recovery Image to v2.6.0.0.

Installed TWRP via toolkit (ROOT button) then flashed SuperSU zip when TWRP started up.

All rooted again 8)

Post by: radiocycle on July 30, 2013, 08:36:35 PM: Hmm, I see the OTA waiting but how 'complicated' is it to re-root CBers? I'm holding off on the update 'til I know the procedure to get back to my unlocked, rooted device... 'course I'll have my new Gen 2, 32GB by Friday so I'll prolly want to just put this one back to stock.

Title: Re: JB 4.3
Post by: CBers on July 31, 2013, 12:16:30 AM: @radiocycle - it's very easy.

As I said above, I used Wug's toolkit to do it.

I just downloaded the latest TWRP and SuperSU.

Then started the toolkit and pointed it at the downloaded TWRP, then hit the ROOT button.

It copies and installs TWRP.

Once done, it boots into TWRP, where I flashed SuperSU.

I have had issues installing latest SuperSU from GP.

I've had to reflash via TWRP each time.
