I am trying to "revive" an ONDA V711. Had a problem with it stop reading a 32G external card. Tried a new formated (Fat 32) card. Would not mount. Tried doing a factory reset, and now everything is installed on internal memory. Cannot access the internal sd card or an external sd card. System starts and runs, can use all pre-installed apps, cannot install any apps from google play. If I run file browser app, I can see 4 folders on internal sd card DCIM, documents, KingsoftOffice. tencent but cannot do anything with them. Tried to do a factory reset using the Power on/Home hold sequence, but says it cannot fine anything on E: drive. Any ideas on what to try next.
Thanks
