I have a Tesco Hudl HT7S3 which was rooted and i corrupted a file in the system and it is stuck in a bootloop. All i can use is adb sideload. I found the stock image and have sent it to the device with adb, but when it opens it i get this error:
In case you can't see the image, here's what's on my hudl's screen:
Recovery system v4.2.41 Now send the package you want to apply to the device with "adb sideload <filename>"... Finding update package... Opening update package... Verifying update package... Installation aborted.
