I did the exact same mod to my CH341A but followed this post https://www.chucknemeth.com/usb-devices/ch341a/3v-ch341a-mod
The seller from whom I bought this dead board actually bricked it while downgrading the BIOS.
He attempted to flash it via CH341A and 1.8V adapter but broke 2 pins of the...
Hi @rsaeon the board was successfully revived.
Just installing the 1.8V chip on ch341a in 25XX slot and avoiding the connection between the PIN 8 of chip and respective connection point on ch341a does the job.
For programming the chip I used CH341A v1.31(1.4) (CH341AFree) version and my cheap...

He was the first guy who reported Gigabyte exploding PSUs in October 2020, his reviews are pretty extensive.

Check their reviews if they have any.
This is beyond repair.
I assumed that the mmcx connectors were ok and only the wires where they make connection with connectors had the issue.
If you can source cheap mmcx male connectors a good quality aux cable then a cable for your Tin Audio T2 can be made.
It can be a fun DIY project too...
CH341A IC work between 3.3V and 5V according to datasheet so simply replacing the Vreg would not work.
I was successfully able to read, erase, write and verify a 1.8V BIOS chip without the 1.8V adapter.
The BIOS chip was MX25U12873F 1.8V 16Mb its from the MSI A320M Pro-VH Plus motherboard...
Hi, thanks for the reply.
I had also thought about this but my main concern is that mine CH341A is a genric Chinese one and it currently delivers 5V on some pins and 3.3V on some pins.
There are multiple threads on internet about converting it to complete 3.3V one, like this thread...
