I know this is kinda old news at this point, but I have a Kindle 4th generation non-touch that I would like to keep using for the foreseeable future. I already jailbroke it and enjoy sideloading .epub books over WiFi using calibre to read with koreader.

Ever since the EOL announcement from Amazon, I have kept my kindle in airplane mode out of paranoia, mainly due to the ominous phrase "If you deregister or factory reset these devices, you will not be able to re-register or use these devices in any way." I know that this is probably not necessarily true for older devices since I'm pretty sure you can skip Amazon account registration in the setup but it is still concerningly vague phrasing.

Because I set my device in airplane mode, I cannot use WiFi sync with calibre or pull up wikipedia articles like I used to. I really want to turn WiFi back on to get these features back. Has anyone heard of Amazon pushing an update or something that actually removes books or breaks homebrew apps? I am aware they don't have the greatest track record for doing the right thing in this regard.

Also, is it possible to set up my kindle or my network so that it can only access wikipedia, my local LAN, and koreader update servers? This may ease my worries about keeping my kindle's WiFi on.

I typically don't like using closed source software when I can avoid it. To my knowledge, QMK is open source, but VIA is not (as convenient as it is to use). It also requires your browser to use the WebHID API, which is problematic computer-security wise IMO.

Because of this, I was considering trying an open source version of VIA called vial. Does anyone have any experience with using it? How does it compare to VIA?

I think I could also try using QMK configurator to remap my keyboard/create new firmware, and to use QMK Toolbox to flash the firmware onto the keyboard. However, I was reading this keychron blog post: https://www.keychron.com/blogs/archived/how-to-factory-reset-or-flash-your-qmk-via-enabled-keychron-v6-keyboard. It says that "If everything works fine with your keyboard. Please don’t flash the firmware. There is a chance it can damage your keyboard". I am aware that if I unplugged during a firmware update it could brick it, but otherwise it would work out fine, right? Would the reset button underneath the spacebar save me in that situation? It is hard to tell whether this is just keychron trying to go the safest route to avoid tech support calls or if this is actually a valid recommendation.

Overall, what software should I use to remap keys and program macros on my keychron v6 (encoder version)?

I have been using a cheap TKL AliExpress hot swap board for a little while, and I want to upgrade because:

1. I miss the numpad
2. Build quality is better than the average membrane keyboard, but still not great

I'm planning to get the keychron V6 because it is is one of the few keyboards that are:

1. Not ultra expensive
2. Full size
3. Has a knob for volume control
4. Reasonable build quality
5. Hot swap
6. QMK/VIA support is nice

The only issue is that I am not sure what switches and keycaps to get. I was considering saving my money and going with stock switches (keychron k pro reds) and keycaps (in-house "OSA" profile), but I do not know if I will like this keycap profile. My current board has OEM profile keycaps, and those are fine, but I want to try more "spherical" rather than "cylindrical" profiles, and it doesn't seem like the stock keychron keycaps are particularly spherical, at least in photos. If they are more spherical in person, I might go this route.

My other plan I was considering was to try keychron's other in-house profile, "KSA", which seems more spherical to me (https://www.keychron.com/products/double-shot-ksa-pbt-keycap-full-keycap-set), or maybe a mt3 set (but I'm not sure about getting an abs set, my current keycaps are getting shiny). For switches, I was thinking of buying the tried-and-true gateron milky yellows, but I am not sure if there are better bang for the buck options out there for smooth linear switches.

TL;DR: Should I go with stock switches and keycaps to start out? Or should I get the bare bones keychron V6, a spherical keycap set (KSA or mt3), and budget linears like gateron milky yellows?
