If you can determine pack is present at B+ and B- using a meter then you need to check for pack voltage between B- and the upper (towards center) end of the fuse. Keep in mind that the board is coated so it may be difficult to make a connection at the fuse. Or without battery connected check for continuity between B+ and upper end of fuse.

Have you tried using a different USB cable?

Gee, maybe open a ticket with Evolv and link to your posts in this thread. https://helpdesk.evolvapor.com/index.php?a=add&category=1

Sounds hopeful then

15 min later from default settings or the earlier "fix"?

The "Restore Defaults" button under the General tab will set it to how it left Evolv's facility. I recommend saving your existing settings first (File/save as) as a backup.

Just highlight the materials and note the values of the graph. If you put up the window to change it the settings for Ni (or last setting made with EScribe stilll open) will show but nothing changes till you push "OK"

They are not changing back...look at the graph values before you open the small window to change it to see that.

By using Device Monitor in EScribe you will be able to see the standing voltage and voltage under load of the cells when firing. It be good if you could post what they are. There could very well be a problem with the connection between the batteries and battery contacts or perhaps with the cells themselves.

That is how mine is also. There were some corrections made to SP5 so perhaps that reflects that. I really don't know. Edit: from the Early software page "[SP5a fixes a few minor EScribe bugs in SP5.]"

I'm at a loss for an answer, perhaps someone will have it.

Is the cold resistance the same as before you updated/ was the atty warm at the time of the update?

With the idea of keeping things peaceful I'm locking this thread.

On top edge of app, options/user interface/ select "manufacturer"

Samsung ICR18650 30B has a CDR of 5.9 amps. NO WAY, I'm not saying it won't work, I'm saying it won't be safe to do so.

Welcome Tamer, the board is quite efficient but watts is watts. The LED is not there like on the 75. If your concerned with EScribe settings for your batteries... well that will only make your battery gauge more accurate. The cell soft cutoff though can be lowered from 3.09 volts to 2.8 volts.....that will give you a bit more.

Not to worry, the mod is faster than the screen. It knew what the resistance was so it didn't need to ask. Look at it firing in EScribe device monitor to see.

A screen shot showing this (example)

All the screens work with DNA 75, DNA 200, DNA 250 and DNA 60 w/large screen. There is no off, only lock.

My guess is that the dark ones are shorting to each other.

I don't have any first hand experience with that but here's what I think. The ribbon is soldered on to the board and while it can be replaced it takes considerable skill. The extension cable will have to be fabricated or a similar ribbon modified and soldered to existing ribbon and board. You should be able to purchase a new screen for the DNA 20 by opening a ticket with Evolv. https://helpdesk.evolvapor.com/index.php?a=add

What model DNA board is it that you need the screen for?

Example: Here pack voltage dropped from 12.3 volts to 11.8 volts when firing 45/35 watts.
