Update: I tried TFTP upgrade using 5.2.3 from HikvisionEurope.com, but it did not complete. It got stuck at "Complete file transmit". I tried 5.3.0 from same site, and a couple from overseas.hikvision.com, but same result. Later, I tied 5.3.0 from www.hikvision.com/cn and that succeeded. However, not the web UI is Chinese and the language ID (from prtHardInfo) is 2.
By reading some other posts I understand that I can downgrade to 5.2.5 and using mtd hack, get UI back to English. Is that right? if yes, which 5.2.5 should I use - CN version or EN version?
