Another DSO+DMM - Zeeweii DSO3D12, claimed 120MHz/250MSps (june 2023)

[Cricri]

Strange, I've got firmware 3.0.6III, I go through the flashing process with Update tool v1.5.9, Load dso3d12_v3.0.6_III_mod_v2.0.fls, it tells me "0 lost, file success", reboots automatically but I'm still on old graphics.

Hi all,
my DSO3D12 just failed after 6 months of really ocassional use. I believe it was a first really full charge cycle from zero to hero . I used my trusty 5V/2A charger without any QC functions. Unfortunately I did not monitor a charge process - i just found the DSO hot after 3 or 4 hours of being connected. The battery connector is currently shorted, but the PCM did the job - the battery voltage is 4.1V. There is no heatsink on IP2312 (board version 2.0-III) an the IC clearly was on the way to desolder itself. Hopefully it's the only electronic damage... unfortunately the PCB under IP2312 is overheated and slightly puffed.
I sent an email and message to Zeeweii asking for contact, but they did not answer.

Edit: After removing fried IP2312 the DSO works .
