I am confused: if I scroll up to the beginning of this post, I see 2.4 B?
If any of them were alphas or betas it would probably have said so. Ideally the 1.7 firmware should probably have been posted in this thread together with the rest of them (or all of them in the other thread), but there’s a lot of stuff going on here and it’s hard to keep track of everything, so I think we can excuse Pablo if he makes a minor mistake sometimes
We are working on a complete database for all firmwares. It’s almost completed and it will become an important part of our website. But we still have some problems to contend with. And since we all only do this as a hobby, we are also limited in time.
Please be patient, we need some more time.

Yep. Heart rate sensor improvements for dark skin. 
Im mean this topic The Kospet PRIME Official post Now i understand that you moved firmware thread here. But maybe better idea is link this topic not version 1.7b in first post in official post.
Its normal that im not getting any ota updates?
We are a small team of people who do what we can in our spare time to provide this community for everyone.
There is a lot of work to do and obviously one of these things is to tidy up the firmware situation and consolidate threads.
We are nearly there and appreciate your patience while we do our best to sort this out.
Cheers

v2.6 added as full flash in the OP - OTA is already out there.
This one does fix the HRS issue for people with dark skin.

Good idea.
Hello after updating to version 2.6B, after a short time of use the touch screen begins to fail until it stops working completely and you can only use the power and back button you can not even turn off the phone, after many reboots I managed to turn it off and reinstall version 2.5B with the pc. Anyone else have happened ?

You used the firmware upgrade option in the SP flash tool?
You have the 3+32gb Prime 1 ?
There are two versions of the watch - one has 2gb ram and 16gb storage - Kospet Prime light
The other is 3gb + 32gb - Kospet Prime.
