freefrog

I bought from aliexpress a DSO4254B in frebuary 2019.
Its serial Number is CN1842001002475

Currently, my DSO4254B is stuck.

It boots, I can see the hantek logo. then after 30secondes (in average) it prints alternativelly on screen: "ERROR-100" and"ERROR-200".
Then it stays stuck...

I have try to recover partition with F3 using the recover menu.

I tried F2 option too.
F2 and F3 do not solve the problem.
I'am affraid the oscilloscope flash is corrupted.
Could I get a recovering software to fix this problem ?

I thank in advance anybody who can help me.
