Hydron:
As mentioned, there's four screws (and a warranty void sticker :P) holding the back on. Inside you'll find a bunch more screws, and will also need to unscrew the BNC nut and unclip the power supply and fan (I think) to get the internal steel shell and PSU fully off the motherboard.
To disassemble further just keep going with the motherboard/front panel screws, and you'll need to take the knobs off as mentioned. There are probably some more BNC nuts to remove, but as far as I can remember, no nasty plastic clips or anything to trip you up.
DC1MC:
Thanks all for the advice.
I was wondering if anybody knows the mainboard connectors for imx28 serial interface for debugging and FPGA RDY signal ?

It works like a charm, the issue, as I've imagined, was the crappy NAND flash, probably 95% of all the non-booting scopes with different colored screens.

EDIT:
It was the  >:D >:D >:D gremlins with missing keys in the memory dump, second memory dump was OK, all options available, now  is a MSO1104Z  ^-^ plus extra options 0.5mV/DIV, "DG" and "Power Ana(log ?)", does anybody know what is with last two options ?

"DG" could mean Data Generator, how can one access or control it ?
"Power ana", well this is a full mystery to me :-//, any help is very appreciated.
I'll make a new topic about them, this could be interesting for other people as well.

On the other side:
"...dumped 67108863 bytes in 8789.756836s (7.456 KiB/s)"

Please, if you have any ideas about a fast and relatively cheap JTAG adapter either reply here or in my "Other Devices" topic, this "USB Blaster" is beyond pathetic.

Now finally we can close this topic.

As a last resort you can always hardware-enable the 100MHz bandwidth, un-mounting both bandwidth limiting capacitors on all four channels.

Careful! Probably this would require a new calibration of the scope.
