I used the Framaroot app (v. 1.9.0) to root my Lenovo S5000 -- the Barahir exploit worked fine, I got root, was able to install Titanium Backup at long last, but then I made a mistake: since I also installed SuperSU and configured it for the "survival mode", I thought it would be probably OK to accept an OTA update. After the update, the tablet sort of starts, but all apps (including the launcher, keyboard etc. etc.) force stop and all I get is an endless sequence of "OK" buttons to click while the system tries to run them over and over again. Is there a way to "unbrick" the tablet? I have googled for help, but it seems this particular vendor does not publish any resources that could be of use in this situation. I'm able to get to a kind of diagnostic mode by pressing Vol Up during boot, but it's in Chinese, and I couldn't locate any option that would give an output resembling a "flash a zip file" option. And of course, I don't even have the zip file. All suggestions welcome (perhaps exept for "you shouldn't have bought a Lenovo" -- the tablet was a gift). Thanks.
