After the umpteenth request on Aliexpress for a firmware upgrade for the Likebook Note, following download links were provided:
* Document "T103-LB root instruction-(support google) .docx" via:
https://mega.nz/#!h0A0wQbR!vUnWhbjFO...TDljywOA8XOEO0
* Above mentioned document contains a link pointing to a newer firmware archive at:
https://mega.nz/#!7J4B2Sra!bUq-wgUxJ...luO5mAGqrbQtmk
* Requesting a download of the original firmware version Likebook-T103-V1.0.0-2018062819 following link was provided:
https://mega.nz/#!g15BWITQ!-YLzbGQRA...AFba3wbD9vKqeo
The contact person providing all these links warned that the updated firmware is not yet stable. Therefore I haven't yet dared to perform any upgrade since i can't afford to brick the device.
Maybe someone here with deeper Android knowledge could make some creative use of these firmware archives?
