A little hello here.
I'm Raph, I just purchase a second hand Kindle Paperwhite Signature (2024) for half its price (no problem, working good).
I bought it because, thru tests, i've seen it's one of the best ereaders on the market. I hacked it, and if I can use it as I want, I also look after modding.
I've seen a few helpfull sites such as:
https://kindlemodding.org/
https://kindlemodshelf.me/
This forum of course.
Some youtube channels (I have to search)
Have you got some other resources ?
Cheers,
Raph
