Emisar D4V2 Flash Kit Instructions (Official How To)

heat shrink: Keep in mind, I don't actually have one of Hank's kits (I had built my own, with a different key-pcb from OHS PARK). The kits will work out-of-the box. Those pins are pretty small. Good luck with that.

I also would like to neaten it up. The draft was written in Microsoft Word. Problem is, a lot of the formatting in Word gets lost when you cut and paste to the forum post window. I think I spent a good 30 min trying to fix the formatting in my post here.

I will make the video version and also for the Android phone app. The phone section done.
Terry if you don’t mind I will link your first post to my video when I upload it.

I might grab one at some stage (when I get a D4v2) and see if heatshink works.

And totally get what you mean about formatting and the forum. I’ve almost got it neat in a PDF now, need to fine-tune it a bit.

Sure, this is a collaborative project.

Here is the video of Emisar D4V2 reflashing with OTG capable Android phone. Terry please add a ling to the video or this post in the OP. BTW I found much easier to do flashing on phone app then on PC :slight_smile:

The reflashing kits will be for sale on our site within this week, it will be tested before shipping.

Thank you for this excellent video. Doing the flashing with my phone looks much less intimidating than doing it with Windows. I think I can do it.

Wow, nice to see that flashing suddenly got a whole lot easier! I didn’t know there even was an android app. Thanks for all the effort!

I've added your instructions to the first "reserved" reply to my original post. This is exactly the kind of thing I'm looking for - collaboration. I've also added a note at the beginning of my original post:

Note, as these alternate instructions from other BLF members become available, I will add them to the reserved replies below this post.

I guess there's no iPhone equivalent?

Edit: ZozzV6, you might want to add a link to the Nichia version of ToyKeeper's hex file in the comments under your YouTube video.

I don’t know if there is iPhone version.
I added Nichia link to description.

The reflashing kits are for sale now.

I’m not sure if we should offer the OTG adapter, if you already have the OTG adpater, please forget about it.

ok this time i need to learn how to flash :slight_smile:

im still using window 7 does it make much different? :open_mouth:

Wins7 does work, I have tested both Win7 and Win10, both work the same.
I recommend to use the phone to flash the firmware, much simpler.

Awesome!

Thank you,Hank. I just ordered mine. Many phones come with an OTG adapter, but it’s nice that you are offering these for those who misplaced theirs, or never had one.

Terry,
A good set of clear instructions. Most anyone should be able to follow.
Here’s a thought, Make a .BAT file that has the commands, along with the pauses for outputs to check for communication etc.
One for the Nichia and one for the rest.
Then it will be a no brainer for the PEBCAK challenged. The hardest part would be getting the driver installed.
BTY, heck of a soldering job on your homemade pin card. I would never got those darned pins on that card in line to work.
All the Best,
Jeff

Yes,with the app in the phone, the reflashing process is like a piece of cake.

haha, the last time I made a .BAT file, Ronald Reagon was president.

The soldering of the pins is really challenging, especially for the mass production.
We have finally managed to get it done with enough precision.

Before you hit “go” button, please make sure the pins are well in contact with the reflashing pads,
and hold your hand still in the reflashing process.
Well, even if you fail, not big deal, just try again. (I have tried to remove the pins in the reflashing process,
the light will not work anymore, but after reflashing again, the light will come back to normal)

This one could use a bat file… :smiley:
