Software testpoint service works for device with up to 10.0 Android, EMUI 10!

Contact support if not sure!
"Software Testpoint" should never be considered a guaranteed way to put a mobile in TP mode

Step 1

Open "Update by TP" tab, choose "Enable software testpoint" option

Step 3 
Phone may be in following modes: 
 a: ADB (recommended to begin with, no need firmware file)
 b: Fastboot (need to select firmware (proceed to step 5))
 c: Update mode (need to select firmware (proceed to step 5))

Step 4

Enable usb debugging
If doing from FASTBOOT or UPDATE mode skip this step

for ADB mode necessary to enable USB debugging

Step 5
Select file
If doing ADB method skip this step

Select firmware file for your mobile, same or higher version Android, preferably same customization
(We don't have stock roms and do not help finding them - files on support area do not suit for this!!!)

If process ends with an error, try putting a check mark on the option below selection. Use it only if process without it failed or firmware is different region or lower version

Press "Do job"

Step 6
Monitor processs 

if ADB mode, allow usb RSA finger key if prompted


Wait for message indicating process success, Phone will switch to testpoint mode shortly after (Testpoint mode is completely black screen, phone only shows in ports if installed)

WARNING! If phone does not appear on DC-phoenix in ports window, you need to apply drivers manually! Go to device manager on computer and locate your device, should look like this:
