[Q] Downgrade Android KitKat for Jelly Bean - Android Q&A, Help & Troubleshooting

Good morning (in Brazil)!
I am Brazilian and the level of my English is regular.
Recently upgraded my HP 1401 8 tablet to android 4.4.2 kitkat with the image I downloaded from the HP Web site and applied by the sdcard (apply update from external storage).
I've been trying to reverse the update without success. I can not go back to the factory system the jelly bean 4.2. Any of you could help?
The equipment does not have root access and still in the factory warranty.
I look back.
A hug. Thank U.

[Q] jelly bean 4.2 for rooted acer iconia b1-a71 tablet?

Hi there,
I recently purchased an acer iconia b1-a71 tablet. It has come with android 4.1.2, and there is no further system updates are available.
I would like to upgrade to jelly bean 4.2 - my reason for this is because I can't seem to bluetooth pair my tablet and htc one together for internet tethering. I've read that jelly bean 4.2 may fix this.
I've been searching around and found a few different posts here, notably regarding rooting and upgrading the operating system version.
I saw this one here:
http://forum.xda-developers.com/showthread.php?p=40418380
which says:
ps .My device ( Acer iconia b1-a71 8gB) OS is android 4.1.2 (B1-A71 RV04RC05_TWN_GEN1) want to upgrade to android 4.2(B1-A71.RV05RC05.TWN.GEN1)
so I upgraded to RV05RC05, which I was led to believe contained jelly bean 4.2 - but the tablet still says its 4.1.2.
I also rooted it using this page:
http://forum.xda-developers.com/showthread.php?t=2240029
but it's still the same.
So may I ask - is there actually an operating system update to jelly bean 4.2 that someone has developed?
Or, is there a way that I can bluetooth pair for internet tethering (from the phone, to the tablet) without the update?
I'm a little confused because my understanding with android was that it was essentially device agnostic - and that if I rooted the tablet, I could technically install any android version onto it, including the latest.
Any thoughts would be appreciated - I have a technical background but I'm relatively new to the android space.
Thank you

The latest updated stock version for b1-a71 is sadly still 4.1.2 RV05RC05 all over . Acer sucks too! Acer community mods never replies and instead delete accounts if people ask for its update, and just sends automated messages to be just dependant on other people if they get an update in their region and then we might get in our region and that poor stuff!

[Q] Updating from VRUDMI1 to 4.4 with root?

So I've been running stock rooted 4.2 for a ridiculously long time now, I've been putting off updating it, even though it seems like a pretty easy process. Now all the guides are for how to accept OTA from 4.2 to 4.3, or from 4.3 to 4.4. Any one know how to go directly from 4.2 to 4.4, or where to find a factory 4.3 image and flash with root so I can update to 4.4?
