Hantek LCR 1832C unlock
ZhuraYuk:
I recently purchased Hantek 1832C nice looking LCR meter which promised good specs. There is older model 1833C which can go 100kHz and change test levels voltage. I hoped to unlock it with modifying firmware in same way as with similar portable oscilloscope Hantek 2C42 > 2C72. But after making changes the only thing that changed is system description, higher frequency setting remained locked. Obviously there is mode differences in firmware as well.
Does anyone have 1833C model to share their firmware? I would be good to have dump of main program flash and boot loader as well. You can easily dump it via ST Link adapter and SWD interface
Attached my original and edited firmware files.

Would be nice to share the original fw you dumped before making any modifications, someone could have poked in it ??

Also known as Hantek TO11 and TO22, they are ODM versions of the 1832c 1833c at cheaper price on Aliexpress

I buy 1833c and run calibrating with connected type-c external power, now a can`t use device on battery power - only with external power. I think this is firmware bug, a iam ready to help you for dumping stm, but my device are corrupted :(
