Hi! I installed BIOS version 603 and Windows image version 1231 (see mega mirror at first post) and everything works now like a charm, right after the installation (no more work needed). No issues after full windows updates installation either. Wifi is perfect. My issues with 128 GB SanDisk MicroSD disappeared and now it is always detected without problems. The tablet turns on at first try (before sometimes I have to try it several times)
I have received, from vclemon (the seller), a new version to upgrade v200 from 32 to 64 bits. Right uploaded today by Chuwi. File is marked with no. 1231 (the link in the first post is for 1215).
I try to contact with vc Lemon for Win 10 32 bit and answer me :
my friend, it is confirmed that the chuwi factory has solved the problem of 64bit, and the technology person is now making the software for upgrade, will upgrade on the official web within 2weeks, please understand and later you can also uprgade on the official web, if anything more need our help please feel free to contact us, best regards-susan
