If wanted I can try to translate the solution... but my english is not so good. But if it is wanted i will do my best.
I and a few other german people have problems after Rooting the Vodafone SmartTab 4.
At first I would explain what i have done.
1.) Rooting the device with Framaroot -> all working good
2.) Want to flash the official 4.4.2 Update -> Warning that my device is rooted, but it is still downloaded
3.) Installing the Update -> getting this Error at automatic and manuel: Look at the Attachment please
4.) Unroot the Tablet with Framaroot -> didn´t function... Updater says the Tab is rootet... same if I trying it with the Unrootoption in SuperSU
I have the Original Recoverie on the Device and only the rooted Vodafone (yes i rooted it again... the unroot function correct, tested it with the Root Checker App).
Does anyone know a Custom Recoverie and a CustomROM for this Device? Or have anyone a Idea how i can put the 4.4.2 Update on this Device?
Thanks for all your help!
PS: If someone need the Update.zip from Vodafone... (<500MB) i can Post the Link in a PN.
PS2: From a other German i get the information that this Device should be a "Alcatel OneTouch Pop 8", Model: P323X, if this helps.
