I bought EBD-M05 Electronic load, from bellow link:
https://www.aliexpress.com/item/EBD-Mini-V3-battery-capacity-electronic-load-tester-tests-mobile-power-charging/32614219909.html

After downloading EB tester v1.8.5

I tried upgrading firmware but something went wrong and now device does not work, I have attached picture after firmware flashing, please help me to flash or restore with original firmware. Thanks in advance.

What MCU it has and how you tried to upgrade the FW?

Is it same as this, which has STM8 MCU?

If yes, then you might need something like STLINK programmer and proper FW binary to make it alive again. That JP4 is probably SWIM programming interface. See e.g. http://digital-wizard.net/stm8_tutorials/programming_stm8_using_swim for more info.

Hi @wictor

I'm looking into purchasing the same model (or an EDB-USB+). But this one looks more interresting for generic usage (not specific with USB)
Could you please kindly comment on your experience with this unit ?
Or if you know links to some evaluations & tests, I will appreciate.
Many thanks

Best regards
