* Another approach would be to unsolder the battery connector from the PCB and either replacing it with one that faces up and offers more clearance or using its pieces to achieve something similar.

Soldering the battery directly to the PCB seems quite easy, just remember you have done it to avoid ripping the contacts if you pull the cables. If the battery last for some years you can apply hot glue to avoid it.

But upon writing this post, I astarted thinking that simply trimming the top with sharp scissors is the quickest of all quick-and-dirty approaches, allowing to insert a card at an angle and bypassing the battery connector. After trying that with my donor socket mentioned above, I decided to carefully bend the oscilloscope's microSD socket top up with a small screwdriver instead, allowing me to insert and remove cards after unplugging the battery without further modding.
Please note that the nineth contact of the microSD card socket (allowing to detect whether a card is present or not) is not connected to the F1C100s (while all others are). Hotplugging is probably a bad idea.

BTW, I have PCB V9.15 with FW 1.3.0C

FYI. A few weeks ago I desoldered the battery connector and replaced it with a compatible connector that had red/black wires attached to it, so I could insert a microSD card without having to mod/replace the microSD card socket. I tried that special "jump to FEL mode" SD card image but it did not work. Either I did something wrong or the microSD socket is not wired up fully/correctly for the F1C100s bootrom to detect/read from the microSD card :(

Hi
could anybody offer to download the mos recent  DSO2512G firmware compatible for the pcb v 9.15?
I'm also have a problem with the channel 1.   the offset  it is starting with 5VRMS . It looks  any internal reference is damaged. Did anyone have this problem? if yes , is it a HW problem or  just FW update could fix the problem?

Hello friend, I would like to join your discord server, and also know how you linked the oscilloscope in that way through the java app to widnows, greetings

I actualy , tested the channel 1 and noted  the imput is not working. The equipment is not measuring anything. When i connect the osciloscope - input 1 to the signal generator , the osciloscope doesnot measures , in fact i feel it is instable, like the signal isnot going to the measuremet circuit. the offset also  set to -5V RMS. Does anyone have any idea about the origin of this problem? I suppose the input 1 burned. I do not have the schematics of DSO2512G, so , any information would be helpful.
Detal: Channel 2 is working properly , only channel 1 has this strange behavior......
