On July 7, I wrote to technical support, because my hantek DSO4254B stopped starting, the screen remains black after showing the hantek logo, when pressing F2, it said, failed recovery, they answer me and they refer me the Next link https://www.eediscuss.com/forum.php?mod=viewthread&tid=14831&extra=  I did what I was saying, which is to extract the file in a USB and then go to hantek and choose the F3 option, the process starts, the device restarts, but the same thing happens again, it does not start, I will comment on what happened and for 10 days they did not answer me anymore.

I need to repair my problem !!

I have the same problem, the screen went black

The nand files are corrupt
Also the recovery ones to solve this we need a copy of the complete Nand, you need a nand programmer and reprogram it...


But first we need
#1 A person with this device working in perfect condition.
# 2 And with a Nand programmer to donate all his information to us ...

This should solve any problems regarding: boot, firmware, recovery, and OS problems ...
