Fixing a borked Hantek DSO5102P
(1/1)
aijii:
Hi guys,
First up, what a great resource this forum is.
My father in law has a of DSO5102P.. that doesn't work. I'm trying to fix it. It worked once, then wasn't used for a year, then now it doesn't boot, just a boot loop with a blue screen.
I've read through Tinhead's extensive thread covering the hantek hacking business... connected a usb-uart to the serial por and can see the following:
*** Warning - bad CRC or NAND, using default environment

This Board: SDRAM is 64MB; LCD display size is: 800 X 480
Press Space key to Download Mode.!
SD:File System init failed!

And then I get the following later on:
UBIFS error (pid 420): ubifs_decompress: cannot decompress 2753 bytes, compresso
r lzo, error -22
UBIFS error (pid 420): read_block: bad data node (block 195, inode 649)

I'm hoping that the NANDflash memory isn't toast and I can recover it. The problem is, I don't have anything to recover it from. I'm struggling to find a whole NAND dump on the web that I can download and try out, just individual firmware upgrades which I read aren't enough for a complete recovery.
Any suggestions ? Not sure what to do..
