Help restore SDS1102CML+ after unsuccessful flashing

<< < (5/19) > >>

We are both working on this ATM and I have a unit unpacked trying a few things.
The recovery files from Siglent only work with V 19 or 20 FW according to them.   :-//
I will talk to them more in the next few days.


And BTW I'm looking at those CML+ key press sequences you posted a week or two back......no success with them yet.  :(
Others I know about  :-X work OK so I'm not sure if I'm in the right mode to get yours to work.  :-//

Zhenja:
Due to the rush and my carelessness, I “erased” the bootloader. The device no longer turns on at all.
There are 3 ways left:
1) Soldering iron and programmer - filling in the dump (here I just do not have it)
2) find a way to flash a nand flash without a soldering iron (but there is no dump)
3) buy a new device and NEVER UPDATE IT MORE.

Please leave the HW until we get a fix from Siglent, see my findings below.....

Oh FFS Siglent !  |O
Version 6.01.01.21R2 will NOT load over V20  >:(
Further, warnings that FW update is progressing so do not cut power NEVER finish, even after 10 minutes !
AND from the update instructions:
10. A window will open showing the system updating and progress bar . When it finished, The SPO will restart itself.
RUBBISH !  :horse: :horse: :horse: :horse:

Stern mail will be found in their inbox tomorrow, this is simply not good enough !

If these failings are the cause of Zhenja's problems then his unit should be fixed at zero cost !

The message to NOT cut power NEVER finishes !
The FW is NOT installed ....NO progress bar and the unit does NOT auto reboot as indicated in the update instructions.

3 different USB sticks tested ! Factory Default tried .......FW's broken JIM !
