Hello, you just need to connect the device with a USB data cable, turn on the USB debug mode of the device, then open FileToMisPOS.exe and click Download FSK. pls check.

thanks, but we can't do anything on the device, the error message block any function... We couldn't turn on the USB debug mode, please help us!!!
And the tool FileToMisPOS.exe show an error to open (0xc0000279), opening in Windows 10 22H2, please, we really need help, we have 50 devices all TPS900 with the same error...

After install correct drivers, the app work perfectly!!! Thank you so much...
But we have 50 devices with the same problem, the app don't work for all??? we need a different app for each???

---

If you have 50 devices, you need to unlock them by scanning the code. When you turn on the device, it will be prompted with FSK, and there is an option below that is OFFLINE repair. Click it and a QR code will appear. After scanning the code, a string of serial numbers will appear, and you need to send the serial number to me.

we don't show the option "OFFLINE repair", and other issue is that device show "Developer Version", how we fix it for all???

Considering that the machine is very old, it may be caused by the RTC battery, which can be solved by replacing the battery.

---

yes, the battery RTC is a problem, we solve that in each device, but the problem continue after that, with the tool FileToMiPOS.exe we solve the FSK error in the first device, how we solve the same error in the others???
The other problem is the "Developer Version", how fix it???

---

Hi. There are some questions I want to know.
1. How many machines still have FSK problems? 2. Why are some machines converted to development versions? How many machines have been converted to development versions?

By the way, pls check the Anti dismantling Conductive colloid is installed well or not. The FSK problem may be caused by the Anti dismantling Conductive colloid falling off during disassembly.
