[Q] Updating to 2.2.1 and Rooting?

[rogvid700]

Hey guys!

I have the US 16GB WiFi only model of the SHIELD tablet, it's rooted, bootloader is unlocked, and I'm running 5.0.1 with a custom recovery.
I'm just a little confused as to how to updated to the 2.2.1 software that was recently released. I'm still on 2.1, and when I try to update it asks to update to 2.2 rather than the current, 2.2.1.
However it's been awhile since the last time I installed an update and I forgot the process in order to flash updates and make sure SuperSU is installed, etc.

Can anybody help me out and give me the few steps I need to take in order to make sure I still have root and my custom recovery installed as well as the 2.2.1 update? Thanks.
If you need anymore info just ask.

*UPDATE*
I downloaded the Incremental OTA update for my model from here, and used the 2.1 - 2.2 MEGA file.
I put it on my /sdcard/0/, and tried flashing it via CWM and I got this error:

Package expects build fingerprint of nvidia/wx_na_wf/shieldtablet:5.0.1/LRX22C/29082_493.9700:user/release-keys or nvidia/wx_na_wf/shieldtablet:5.0.1/LRX22C/29979_512.4856:user/release-keys; this device has nvidia/wx_na_wf/shieldtablet:4.4.2/KOT49H/22229_

Any ideas?

Seems like your trying to upgrade from 1.2, to 2.2....

Are you currently on Android 4.4.4?

 

[rogvid700]

I can confirm that I am running Lollipop 5.0.1
But yeah I noticed that too. It thinks I'm running 4.4.2?

Anyone? Any ideas?

Maybe there's just a glitch, or a ghost line of code preventing it from flashing.

My only advice would be to do a full wipe and just flash the full OTA instead of the incremental one.

 

[rogvid700]

What's the safest way of doing this?
I have Titanium Backup, and do I just use CWM to do a full wipe? Or something else?
And I'm sure it'll lose root if I do a full wipe. Would I just flash SuperSU after flashing the full OTA in order to get it back?
Sorry for all the questions. I'm not a total amateur, just not an expert.

Exactly what you said. Full wipe, then reflash SuperSU.

You'll also have to reflash CWM, as flashing the full OTA in CWM, flashes the stock recovery.

 

[rogvid700]

Okay so, I need to put the full OTA on my device, and then wipe? Or vice versa?
Because won't the full wipe remove the full OTA if it's on my device?
So, full wipe, flash OTA, flash CWM, flash SuperSU? (Please correct me if this order is wrong)

Because u cant do that. You cant flash an incremental OTA via custom rec.

If u are rooted you need to flash latest FULL OTA vía custom recovery, reflash supersu andnyou should be ready

There is no need to full wipe everything. Just "dirty flash" it. Make a nandroid just in case.

1- Make nandroid
2- Flash full ota
3- Wipe cache & dalvik
4- Flash custom rec
5- Flash supersu

That should do it.

 

[rogvid700]

So the nandroid backup just won't work through CWM, it fails when trying to backup /data.

I've tried wiping the cache and still nothing. If I just want to go ahead and do a full wipe, where would that be in the steps you gave me?
Thanks!

Yes this is correct. And when I say full wipe, if it's not obious, DON'T wipe internal storage, or External SD card.
