Hantek DSO1152S - Wont boot after firmware update
« on: July 13, 2014, 02:27:01 pm »
Hello,

I was just wondering if there is anyone on here who may be able to help.

My scope was running the stock factory firmware on my Hantek DSO1152S (Handheld 150Mhz isolated scope), and I noticed there was an update available as there were a few bugs I had found, such as the MEAS button not being able to measure any other channel other than CH1. So I thought I would try a firmware update.

I went on the Hantek website and downloaded the latest update. Put it on a USB drive, went to the update menu and placed the USB drive in the scope, waited for it to be detected and then clicked update.
It did 10/10 on the process update and then restarted. All looked fine.
Now I am in a boot loop and it will not get past the main start screens. The first shows the Handheld oscilloscope picture, and then the 2nd screen shows the Hantek name, website and the version number. It then restarts and repeats over and over.

Not sure what could have happened, unless the firmware was somehow corrupt?
Was plugged into AC, didn't touch it during the update.

Is there a way to force an update or restore it?

Any help would be appreciated. Currently dead in the water and urgently needing the scope working again

Kind Regards
WanaGo

Seems someone else may have encountered a similar thing to me...

I couldnt get the hantek.org forum up, so I had to seek out a cached version, here: http://webcache.googleusercontent.com/search?q=cache:http://www.hantek.org/asken/iaskdetail.aspx?id=2014052620325673

Can someone please explain if they know the process to fix this. I am happy to open the case and connect a TTL to serial cable and do something with Linux if required.
I have a Ubuntu VM I could use, and have 3.3V TTL cables, may even find a 5V one...

If someone could help that would be highly appreciated

Kind Regards
WanaGo

Here are some photos of the internals if this helps

I assume the UART header is the one marked J801, and the pin with the arrow marks the 3.3V pin, followed by GND, TXD and RXD ?

How do I connect to it, what program? What baud rate etc?
What do I need to do?

Any help would be appreciated

Thanks in advance

OK Yip that seems to be the UART port.

Baud seems to be 115200

Here is the output after pressing power button ON.

It talks about pressing Space at the start, to enter download mode
Would this then let me download an older firmware to correct this mess?

It talks about pressing Enter later on. I did this and it enters the Linux prompt.

Not sure what to do in either though

Yes thanks - have sent him a quick PM. Thank you.

Pressing Space resulted in this, which is the download option.

Not sure what I need though.

More playing, but nothing discovered, just more questions..

Thought I would try to decrypt the update file. Found a bit of info on this site, but I didnt know the password for the up file.

> gpg -d dso1kb_2.01.1_DSO1152S\(140408.0\).up > dso1kb_2.01.1.gz
gpg: CAST5 encrypted data
gpg: encrypted with 1 passphrase
gpg: decryption failed: bad key
gpg: block_filter 0xaf0730: read error (size=16233,a->size=16233)
gpg: block_filter: pending bytes!

tried what I found on here, and guessed at a dozen more, but nothing seemed to work.

Had a bit of a look around in linux, but it seems after a very short time, maybe 30 seconds?... it reboots

CAST uses 128-bit keys, so if you brute force it  expect to take 2^127 attempts. Also, many keys may end up giving you an executable binary, just not the right one. Note the universe is roughly 2^80 microseconds old. Source: The Block Cipher Companion, Knudsen and Robshaw.

If you want to save time, the key is somewhere in the machine doing the decryption and CAST is a symmetric cipher so you can encrypt with the same key if you want to load your own software.

yeah wasnt hopeful guessing would work, however the passwords I had seen on this forum and others were the model numbers of the scope, or the family models.

I tried:
dso1000
dso1000s
dso1152
dso1152s
etc

No joy.
In terms of hunting out the key on this machine - wouldnt know where to start to be honest.

Is it a linux process that decrypts the file? If you're lucky it'll be a script so they'll probably use the openssl command. I use a script like this:
Code: [Select]
#!/bin/sh
openssl des3 -d -salt -in secret_file.tar.gz.des3 -out secret_file.tar.gz
Somewhere on that machine will be a similar script using cast instead of des3. Maybe try an update and run "ps" at the same time to see what is doing the decryption. If it's a binary linked with the openssl libs then hexdump that binary looking for the password which you know will probably start with "dso" and be NUL terminated.

Edit: Maybe just build your own openssl libs that dump debug info giving you the passwords used on the machine. That would be quickest.

great, thanks!

Ready when you are.

Noticed when logged in to the linux console, after a few minutes one of the relay clicks on and off, and then again, and then again... and gets faster and faster. I shut it down after a couple of clicks as I dont know why its doing it.
Thought it was due to it getting hot, but I have put a big case fan above the scope board and its still doing it.

I have 2 firmware files, downloaded one a while back but didnt upgrade as I was looking at the 2.01.1 rather than the date.
Didnt think anything had changed.

dso1kb_2.01.1_DSO1152S(140408.0).up

Its that 2nd one that I tried today which got me into this mess.

Looks like I was running 121207.1 prior to that.

i'm on windows, so some steps might be different on windows:

1- go to Hantek OneDrive http://1drv.ms/1cA9vjg and download firmware for your model (DSO1152S_Firmware.zip)
2- unzip that file, you will get dso1kb_2.01.1_DSO1152S(140408.0).up
3- get gnupg, run in command prompt from directory with the *.up file like
 gpg -o fw.tar.tar.gz dso1kb_2.01.1_DSO1152S(140408.0).up
4- when asked type password: 111111
5- now you should have that file fw.tar.tar.gz created in this directory
6- open it with winrar, then the content again with winrar - you will see "tekwayup_client" directory, unpack it to harddrive
7- in that directoy there will be "update" script, in my opinion there is bug, there should be

[cmd] mv /tmp/tekwayup_client/dso.exe   /dso_update.exe

and not

[cmd] mv /tmp/tekwayup_client/dso.exe   /dso.exe

I don't know, maybe it's only me, but i never managed to overwrite dso.exe when it was started, it crashed or didn't got overwritten properly on linux 2.6.13 and 2.6.30 (that might work on 3.x, so on other models, but you have 2.6.30.4).
I think these guys from Hantek, they already forgot that  :palm: One can see in the bootlog "no update file to foud" which
is message coming from script which checks if there is /dso_update.exe in place and renames it to /dso.exe before this will be started (right after first rebot after fw update) .. anyway, maybe that's only me hehe, but i can kill all my s3c2440 dev boards
with all the DSO/MSO firmwares on it when i do what they did on latest S, B and BV models updates.

Anyway, copy that dso.exe to flash drive (and ensure windows copied it properly before you remove flash drive).

Now let' got to the linux console on your DSO. Luckily you did the major work already, so do following:

1- power up DSO
2- do not push any buttons or you will be in boot menu and we dont need that!
3- as soon you see "Please press Enter to activate this console" push ENTER and or CTRL+C and ENTER.
4- now tpe as fast you can following (and then ENTER)
 
  killall dsod

and then arrow key up (to reply last command) and ENTER, and again :) Until you get "dsod: no process killed".
The dsod is watchdog, rebooting your DSO over and over again because dso.exe not started. Normally one could check with ps x the process id and kill -9 processid, but killall dsod is faster typed (at least for my fat fingers).

Now you should be on the linux shell, without any reboot over and over again. Insert now the flash drive into DSO,
you should see now some messages that it got monted. Check that with

 ls /mnt/udisk/

You should see that copied before dso.exe. Copy it now to root of the DSO, like

 cp /mnt/udisk/dso.exe /dso.exe

then flush the cash with

 sync
 sync

and give executo rights

 chmod 777 /dso.exe

No check if your DSO is working. Go back to / ( cd / ), and type /dso.exe and enter. The firmwar should start now.
I assume you executed before that update file dso1kb_2.01.1_DSO1152S(140408.0).up anyway, so there is not need
to copy other files from that "tekway_client" directory. In case you applied different update, let me know this, then
you will have to copy other files as well.

thank you!

I am on windows too.
Only know how to drive linux as good as I can find answers on google. Assumed that would be the method to use.

Already downloaded the firmware, which got me in this mess in the first place, however will get it from where you stated.

Will report back shortly

Thank you!

btw, when you DSO anyway open, can you please make pictures of the other side of the PCB as well ? I wish to see how they made the isolation, and all these parts from isolation (ADCs, FPGA and SoC as well - but they known) are of the other PCB side.

OK, did all the fix, however still got the boot loop.

Yes I updated the firmware as per the update menu on that latest update prior to all this, then got the boot loop.

copied the dso.exe file over as you said, restarted the unit and its still got a boot loop.

Any ideas?

Ill take photos of the other side while I await your reply

Regards

so you copied the dso.exe, changed the execution rights and when you kill the dsod and run /dso.exe it reboot then still after few seconds? Try to do this as well:

rm /param/sav/run*

and then try to run the /dso.exe

EDIT: once dsod killed there should be no reboot. It would be interessting as well to see what message is coming right before reboot.

What I mean is, before I did what you said....

Start the unit up, Press Enter to get to linux prompt.
If I sit there it will reboot after about 20 seconds.
So to prevent that, I did the killall dsod.
I then put in the flash drive and copied over the dso.exe file I extracted from the up file.
i then did the rest of your instructions about the chmod etc, sync etc. running /dso.exe at this point starts the scope, no problem. All seems fine.
However rebooting the scope again, results in a boot loop like before.

Whatever is normally opening dso.exe it seems is not working.
I still get that same first warning message: "*** Warning - bad CRC or NAND, using default environment"
When I am looking at the UART.

Hope that makes sense

Opening scope now.
