Thanks to digiblur, whose tasmota flash I did today. Here is a link to digiblur's original article. I struggled a bit to find any recent examples of this. So my goal is to let folks know that digiblur's method still works, and add some photos and notes I had on the process.
Coincidently, I have the same kit that digiblur recommends, great minds and all that. You can see the tools in the pics. I also concur that the iFixit kit was indispensible for this project.
Notice it has some little rubber plugs covering the screws. Not sure if they are an improvement, but they aren't glued in.
The rubber plugs popped out pretty easily. Make sure you keep an eye on them, I lost one of them more than once with hiding behind things and such. I love my Weller mat but it was hiding one of those plugs in the corner because they are small. The triangle screws are still there.
The weather seal on it holds pretty tight so I did have to use the plastic pry tools from the iFixit kit.
Looks the same as far as I could tell, but I did a far from thorough check.
Here is with the flashing wires soldered in place. I will blame my solder job on too much caffiene too.
I could not get it to flash any way except the online Tasmota Flasher.My goal is to put esphome on this, but I can't get the bin to build so I will do that later.
One thing to check. I believe the template provided by digiblur is backwards. A quick switch here solved that without issue.
