i bet you have deleted the preinstall.apk as well aren't you? i think if i didn't delete it, with the factory reset should be able to retrieve all the apps preinstalled.
anyone could provide a help here please?

Warning: Here be Dragons. I managed to restore the needed apps without bricking my tablet. If you mess this up, you won't have a working tablet and Lenovo probably will not flash it for you.
You can get a copy of the 75US /system here:
Make a backup of root using OTA Rootkeeper
To restore, all you have to do is copy that system folder onto your /system folder. My root was acting up and kept remounting /system as ro once a second, so I needed to copy using an adb shell over USB. You may have better luck than I did with root explorer or ES.
It may be possible to just run the preinstall apk. I also had issues replacing things in /system while running, but I managed to finish the copy and reboot before the tablet shut down. If you're careful, you could probably load fastboot or something to copy while /system is not mounted.
Tempoarily disable root and apply OTA2
Restore root and check that it works.
Temporarily disable root and apply OTA 2.5
Restore root and check. You should be fully updated with root.
I decided I'm going to leave the stock apps this time. We're 2 to 3 months from ICS, and I really want that update. Since Lenovo doesn't release full, signed images, it's very likely you can get in a position where you cannot update.

I had the same problem with my row tpt. I downloaded the 74_ROW from here:
Copied it to an sd card and update it from the recovery menu. The tablet froze after updating (the android animation stopped) and i had to reboot it manually but it worked. iirc i did a factory reset here but i'm not sure if it was necessary.
After that i was able to update to 89_ROW.
