Tab2 upgraded, major encryption gotcha, Titanium Backup to the rescue, and all's well

To my surprise, connecting the Galaxy Tab 2 via cable to a PC and using Samsung's much improved Kies did permit the upgrade.

And then locked me out of the tablet entirely, demanding a decryption password at bootup ... although the tablet wasn't encrypted. Oops. A left-over, to be sure, from the botched encryption job I did when I first rooted the tablet. Heh heh. Titanium Backup Pro to the rescue!

Now all upgraded, programs and data restored, encryption working quite correctly at last, and Swype not being quite so much of a performance hog as before!

unroot upgrade then root

So I have a rooted samsung. If I unroot my device and then upgrade the firmware, would I be able to root it again using cf root?

Looking in the other forums, I now know the answer to this. For others that were wondering, the simple answer is "no." However, if you use SuperSU Pro, there is a possibility that you will maintain root.

I have been having issues getting this method to work on my S3 for about a week now. The COM port icon stays BLUE and doesn't turn YELLOW, it does however recognize that my phone is connected by saying 'added". If I try and proceed with the root method anyways the program will sit there for about 5 minutes or so once I click start and then I get the FAIL message in red...I have tried doing it on two computers and I have also tried to reinstall the S3 driver as well as download the other two necessary files a few different times.

Does anyone have any suggestions?

Hi

I have some stupid questions myself.

I got new SGS 3 International version

Updated to 4.1.2 and rooted with this cf-auto-root. Everything works fine so far

1. If I want to install custom Rom now I guess I cant just go into recovery and flash cm10.1 with only cf-auto-root on my phone?

2. I have latest CWM Recovery (CWM Recovery Touch 6.0.1.9) ready to flash with odin, can I just flash over my rooted phone or do I need 1st to remove this cf-auto-root???

thx
[Android Software/Hacking General [Developers Only]] melvinaury:
You only need to wipe factory reset and then install the ROM for a clean install or dirty flash just wiping dalvik cache and install. It is recommended to wipe factory reset before installing a new ROM. You can backup you're apps and data with Tibu (titanium backup), but only user apps not system apps.

Is that, i have to use the old CF root to make traingle away work. BTW i used Triangle away 3.26 and i was able to successfully unroot my Galaxy S3 rooted with CF root. Or is that the triangle away will not work with lollipop root ?

Hi [MENTION=631273]Chainfire[/MENTION],

Thanks for such a fantastic method for doing this!

I also just tried the Nexus 5 (hammerhead) CF-AutoRoot after reflashing with the 6.0.0 factory image released yesterday. Booting CF-AutoRoot (the version for Android 5.0 on your site) went fine, the whole thing ran as per usual without any apparent errors, but when the phone rebooted it got stuck on the booting animation (four animating coloured circles). At this point adb still worked so I could get a shell on the device, but I'm not really sure what to look for - the su binaries were in the expected locations and running them did nothing (they just exited immediately returning 1) which I assumed was because the boot process was still active.

Note that I did all this *after* booting the device with 6.0.0 for the first time, so it wasn't the app cache being rebuilt - that did indeed take a while, but finished successfully before I ran CF-AutoRoot.

In the end I just reflashed the system partition and everything went back to normal and the phone finished booting, but of course without SuperSU installed.

If there's anything I can do to help test or work out what happened, let me know. I'm also happy to beta test any changes if you don't have access to a Nexus 5. You've asked for a recovery image for unsupported devices, so here's the one for Nexus 5 / hammerhead for Android 6.0.0 (9.8MB) in case that helps. But like I say, the install process ran with no errors I could see, so perhaps that won't be so helpful.

Thanks again for your amazing efforts!
