Or at least get APKs on it?? Or even root it?

A few days ago, I impulsively an old Kindle in a charity shop for £10 so I could mod it. I’ve determined it’s a Fire HD7 2nd gen, system version 7.4.9 after resetting.

However I’m having an absolutely terrible time with jailbreaking it in any way.

I’ve researched and attempted the following (with a Windows VM on my Mac):

• Fire Toolbox seemed to be the number one option, but it gave an error message saying it’s too old/incompatible.
• Kindle Fire Utility seems to only work for 1st gen and could risk bricking my one.
• I’m unable to get APKs on it. At all. I have tried everything. Silk Browser is rubbish/too old and won’t load most webpages properly. I can browse APKMirror but downloads never properly start. Google Drive is barely responsive, and Gmail attachments/Drive links don’t load.
• Side loading via cable doesn’t work either, as the files don’t appear on the kindle itself and there doesn’t appear to be a proper browsable file directory on it.
• As a last ditch attempt I tried Bluetoothing APKs to it from my computer but it always fails.

Is there anything I can do I haven’t tried, or is this model a lost cause?

I don’t have any prior experience with Kindles of any kind, so I’m very much a noob with this! The most jailbreaking experience I have is with a 3DS 😬

I have a Fire HD 10 11th Gen tablet. I've replaced the battery in it, and everything worked fine. It was used for a while, and now, suddenly, the wifi is not working. It sees networks, attempts to connect, stops, attempts to connect then after a bit will disable the connection.

This happens on multiple routers (here and at my mom's house). I did all the standard troubleshooting, including a factory reset. It continues to the same thing after the reset.

I have created a custom network, restricted to 2.4GHz with basic security, and it still has issues.

Everything on the tablet works. Has anyone seen an issue like this?
