Help with Tesco Hudl1 restoration images

Recommended Posts

Hi All,

I have bought my children Hudl a few years back that has now be gathering dust due to a virus which affected the device. The virus manifest itself in showing all kind of indecent adverts and does not allow the user to gain control of the device. 

I tried the factory reset process but that didn't help so for the past few year I simply put them away as I could not afford my 8 and 10 year seeing these images. I recently bought myself a book with came with an epub version so I am now looking for a way of restoring these 3 tablets so I can use them for at least reading as the devices are physically and electronically in very good condition.

I tried downloading the images found here  but the URL no longer works. Over the weekend I came across rkflashtool which I was able to use for interrogating the hudl through Ubuntu 16.04 terminal. Using this interface I was able to read the various partition such as the "kernel, boot, system" etc.

I was also able to mount the "system" partition on to my my machine " see below.

 I was wondering if someone has hudl restore images that they can share so I can use to flash my devices back to its original state. I don't mind whatever solution is available Window 7 or Linux. A brief description on how to reprogram the device would be most highly appreciated. Many thanks in advance.

I believe you'll need rktools (windows), not rkflashtool (linux) to use this backup. It's a backup of the stock 1.3.1 software that I downloaded from here some years ago, but I've not used it myself.

Either way, the file is re-uploaded: here

Hi flurry,

Thanks for your reply, I was able to download image and re-flash one of my Tesco hudl's. I would try and repeat the process on the other 2 hudl tablets but thought to express my appreciation for your help.

Regards
