Hello, I'll tell you the problem, the equipment is new, at first I put a wrong hack on it and it went from 200 mhz to 100 mhz but it worked well, then I tried to install an official update and the equipment stayed on the logo, the only way I could get it out of there is to install another firmware of another model, a 4-channel version, it passed the logo but everything went crazy, the tips didn't work, then I tried with another firmware and from that moment on it didn't turn on again, not even the logo and the worst thing is that you can't force the firmware installation with the green help button, I think the pre boot was damaged or something like that.
If anyone has an SPI file to get rid of that error or some other solution, I would appreciate it.

Hi, dunno, am not familiar with your Rigol DS-1202Z,
but often updates are not so necessary for electronic measurment devices .
But I do know there is a bunch of differences between 100Mhz & 200Mhz.
And simply an update won't resolve that, periode.
There is a lot of hardware involved ;-?
You could try a "cold" re-flash, perhapse the system kept somewhere in a ROM-part
the original version, . . .
But please, quit thinkering with things you don't know about.
What amateur electronics hobbyist needs more than 100Mhz :phew:

hello,
see here for example:

what are you talking about "cold" re-flash, And as for the MHz, my oscilloscope was originally 200, but due to my clumsiness it was set to 100 MHz.

I have already tried all the options in that link, the problem is that the computer does not install the firmware by force when pressing the help button, the screen goes black and after 4 minutes it turns red with all the LEDs flashing.
-
The HELP button must be pressed three times immediately after the short beep.
Is there a short beep?
-
It no longer has a short beep when you turn it on, the lights only flash once and do nothing else until after 4 minutes the screen turns red and all the LEDs flash

If anyone has a solution, even if it involves risks, please tell me what to do. The truth is that I have that oscilloscope lost. If you have to unsolder the SPI, I have experience in micro electronics and I have a tool for programming memories. :-BROKE

I think for recovery you need a flash memory image of a working oscilloscope.
Of the pitfalls - the serial number and calibration may fly off.
Maybe it is easier to contact Rigol to clarify the actions.
