User2288 Yes, you are right. I am not a rom maker. Devices in metion are (way) past their official support. But I am not comfortable with recycling or scrapping them. Thanks for the replies. I gave it a thought and will find alternative offline use for them like ebook reader, tv remote/ps4 controller, note taking and so on.
Worth checking out https://divestos.org they do the best they can to keep devices secure as they get older, they make the securoty implications clear
There are charities out there that are looking to obtain old devices even just for their ability to dial 911 such as https://charity.lovetoknow.com/donate-cell-phones and also some charities looking for 911 devices for homeless people etc for emergency use only. Check your area for these.
I have removed a post promoting dubious "debloating" guides, since that often does more harm than good, and it can result in you damaging your device. While OP here is considering doing this on otherwise old and osbolete devices, others may stumble across this thread in the future. Thank you for your understanding.
I will not be locking the thread at this time as there seem to be a couple questions that haven't been answered by OP yet, but let's not treat this thread as a space to recommend dubious stuff please.
zzz I would say both reasons.
Anyway guys, thanks, you've been helpful.
