HP slate 6 voice tab dual sim (HSTNH-B19C) factory image needed

I bought HP slate 6 voice tab dual sim (HSTNH-B19C) from Karachi 6 months back. Since then it was working fine on jellybean 4.2.2 until i got a system update Message from Hp. So i updated it with kitkat 4.4.2 successfully.
Now the problem is that most of the 3rd party applications doesn't support it. The updated software is working fine but i want to revert back to the jellybean 4.2.2 that originally came with the tablet.
If anyone knows from where can i get the factory image than please share a link.
If anyone have a same model with backup image of original firmware then please contact me on my cell no. [edited Cell Number by Moderator]

Hey @Paracha ,
Welcome to the HP Forums!
I understand you're looking to downgrade back to JellyBean on your HP Slate 6 VoiceTab.
The factory image files are hosted on the HP website for your product. The model you have posted is actually the regulatory information for the battery and not the tablets model. If you can provide me with the exact model I may be able to offer a link to the factory image. 
For information on finding your model number please see this guide: Locating the HP Slate 6 VoiceTab and Slate 7 VoiceTab model number.
If you would like the file faster you can go to HP - Drivers & Downloads and enter the model number. Once entered you will find the factory image listed under the Drivers section for your device. Keep in mind that typically the Android OS will fault when trying to downgrade and often rooting the device or using third party apps/software is needed to do this which HP cannot provide support for.
