How downgrade MDI china - satmanek - 02-10-2019
I got MDI china without Wifi which was upgraded to version 8.3.103.117 and GlobalTis V32 supports MDI version 7.14.27.00.
SPS works as J2354 but no other functions. I have MDI Manager version that matches MDI, T2W also works but separate, not with GT32. GDS doesn't work anymore, can't see MDI. I would like to return to version 7.

You have to put it in recovery mode, see youtube. Arrange GM MDI manager the version you want, then connect MDI and press recover button on MDI manager.

You have to push and hold the Powerbutton on MDI and then connect it to a OBD 2 port so that it powerup. Hold it till it Beep / about 10-15 Seconds. After that it is in the recovery mode.
