So its posible to go back to the V2.35 with the help of telnet access.
Hi!
There is easier way to downgrade.
I have flashed 2.39 a long before I found this site. But now I have 2.35 with just PC and USB-key
All has beed checked today on my MSO-X 2012 (originally it was standard 100MHz + MEMUP update with 2.39 firmware).
1. downgrade to 2.37 (it just works)
2. unpack 2000XSeries.02.37.2014052002.cab (ex with WinRAR)
3. extract file infiniiVisionLauncher.exe from infiniiVisionSetup.cab (2.37) (ex with WinCE CAB Manager)
4. unpack 2000XSeries.02.35.2013061800.cab (ex with WinRAR)
5. open infiniiVisionSetup.cab (from 2.35) file in WinCE CAB Manager, find infiniiVisionLauncher.exe on list and delete it
6. add infiniiVisionLauncher.exe (from 2.37 cab) to file list and set all properties like in old file (flags: uncheck all; location: \Secure\InfiniiVision; Hard-coded path checked)
7. file->save and exit WinCE CAB Manager
8. calc MD5 of edited infiniiVisionSetup.cab and update it in recipe.xml file
9. compress all files (ex with CabPack) from 2.35 firmware with edited infiniiVisionSetup.cab
10. flash new file
After this I reflashed scope once again with untouched 2.35 to update modified file but I don't know if it was necessary.
Also I don't know if there is possibility to downgrade directly from 2.39.
Now I have 2.35 in scope and 2.39 from USB (and I didn't need to use python script).
Starting scope from USB key:
NOT WORKS:
- Kingston DTSE9 (8GB)
- silicon power touch 830 (8GB)
- PQI connect 201 (16GB)
- all my no-name keys... (1GB..16GB)
WORKS:
- LEEF Spark 32GB
And I would like to thank everyone on this forum for files/instructions/descriptions.
