Flashing Previous Rom

2018-07-20, 13:16 PM

Hello everybody, i have been working for the past few weeks with lenovo tab4 8 tablets (TB-8504F), and there was sort of a break between shipments in order for us here to configure all of them with our custom settings and application to be distributed before more arrived. All was going well until we noticed that that tablets with the older rom worked well when it camed to start the app on boot but with the newest version it doesn't work. Is there any way of me getting an official rom from Lenovo and flashing into these newer devices?

Best Regards.

Factory images can be downloaded from the lenovo russian forum. Unzip the package for instructions, the flashing tool, and the factory rom.

I cannot find a link to the actual rom on the russian forums and I get malware warning messages all over the place. How is it that Lenovo is not providing links to download the stock images for these devices. The Lenovo Smart Assistant works for me except on this one device I have that is stuck and can only boot into fastboot mode.

Hey, might be a long shot but do you still have this file somewhere on your pc? It is not availible anymore at https://cloud.mail.ru/public/M98p/GqWBPJexy. If you do still have it, could you please share it with me?
