Symbol Repair Parts Co.,LTD. is a leader among handheld computer repair parts accessories for replacement suppliers. Our company concentrates on the development and production of handheld computer accessories. We have a bunch of MC9190s and one of them has started popping up messages saying 'xyz.exe cannot be opened. Either it is not signed or one of it's components cannot be found. I know this is an outdates thread but I did find the barcodes to restore Symbol MC9090, MC9190, MC9200 and many more to factory with the rapdi deployment tool. One of our Symbol MC9190s stopped during boot, the blue line on the top of screen went up just halfway, and stopped there. No warm or cold boot can help, my only hope is the reset from SD card. The Symbol MC9090s are now unsupported hardware and a Zebra sales rep won't sell me a support contract so I'm completely dead in the water even if I am willing to pay for the contract to get the files. There is some strange thing about the interrupt of keypad module. Some times too slow to send the key release interrupt, using same click on keypad，but sometimes keypad interrupt comes within 100ms，sometime 1s. The problem is caused by clock source, but the keypad controller of am572x has no other clock source, so the problem still no resolved. We often purchase the Keypad Module not realising that this is a discontinued product.
