I am pretty sure I saw some backups for the dso5072p on tinheads microsoft cloud drive. I heard he has also shared some files on his google drive. You can also find schematics for most of these scopes on his cloud.

The way in which the backup .txt HELP description should read is as follows: (since english was not his first language, this is what I was able to determine and I have tested and it works)
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Note - the backup will create a dump of all "or" specified "mtd" (aka Mounted) partitions, using the following .TXT files and or params:
- If you create an empty .TXT file with the file name 'oob.txt' on the root of the flash drive, a dump of the OOB file(s) will be created. If you create a empty TXT file named 'omitoob.txt', then an OOB file will NOT be created. (if you break down the .txt file name, the first 4 letters of the second file name is "OMIT" aka "ignore")
- If you create an empty .TXT file with the file name 'dumpbad.txt' on the root of the flash drive, a dump of the file(s) PEBs will be created. If you create a empty TXT file named 'omitbad.txt' the the PEB file(s) will NOT be created.
- If you create an empty .TXT file with the file name 'mtd.txt', a 'grep -f mtd.txt' will be used as filter for /proc/mtd output. (meaning the system will look with this txt file to see what partitions you want to copy to the USB drive). If you DON'T create a file called 'mtd.txt', then ALL MTD partition found in the /proc/mtd directory will be dumped. (meaning, DON'T create this .txt file, so that you will copy all the MOUNTED drives into your USB)
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Keep in mind, each of these files that you create (oob.txt, and dumpbad.txt) must be in the root of the USB drive where your backup script file is located. When you execute the "Firmware Update" feature on any DSO5000 device, the backup script will look for these files and take the predefined action. I did this on my device (a DSO5102P) just last night and I got all the necessary files I needed to conduct a restore should I need to do one via UART/USB.....
Hope this helps in claifying what the file "options" are when doing the backup of the scope's files.
Cheers

dam i love this community.
Thanks so much Rich. That clears up all my doubts.
It would be a big help if you also mentioned what options you used to get your back up. Along with what options will give us the safest and most comprehensive back up.
My original plan was to take backups using all the options and hope that if things went south one of the backups would save me.
But reading your post it would seem you only used the options oob.txt, and dumpbad.txt
Keep us posted on your progress.

Look at the bottom of this threaded post... you will see a link to a file called "Tools_P_models.zip" - the instructions for use are the same as other models.... see a previous post in this thread (on page 128) where I clear up the information regarding the use of the .txt files needed to appear on the blank USB drive (along with the backup script file)

Yes, this hack is still functional for all models of the Hantek DSO's.... on the first page of this thread you will find the necessary information about the various hacks as well as some other features that your scope may be able to do....
