To help you with the problem please contact us via live support chat during work hours when you have plenty of time, you will need to flash device with nv partitions backup for IMEI repair to work on your unit.
Will be able to try out model/country/vendor repair as well.

You can get certificate file by detecting it on HCU via testpoint. See guides on hcu page.
To get partitions backup may use dc-phoenix: https://www.dc-unlocker.com/dcphoenix-emmc-dump

After what it got stuck in testpoint mode? Maybe you used "enable software testpoint" or did something else to device?
