What are the worst tech purchases you or your family have ever made?

I watched a video recently and wanted to know what other have bought over the years.

I bought a fucking Xioami Poco F4 GT near the launch date because I wanted a gaming phone and back in the time I was naive to think mobile games were a thing. It came with a top of the line chipset from the time I bought it (Snapdragon 8 Gen 1), and this shit overheats as fuck and eats your battery even on average use.

I was able to unlock the bootloader around 2023 and so far used only LineageOS, but this year I had to relock the bootloader for a specific usage, and guess what Xiaomi is making nearly impossible to unlock the bootloader again, I didn't know about that and now I'm stuck on Xiaomi stock ROM with 24/7 spyware (I know because I can see the requests log with an app, the fucking package installer app is reaching the facebook domain every few hours).

Such regret OMG. Suck unfortunate series of events. I'm not even using my phone, just basic stuff.

Good thing: I just bought a second hand Redmi Note 10 Pro in a pretty reasonable state and cheap, there are dozens of ROMs to this phone and easy to unlock the bootloader (actually I already started the process just need to wait more 160h). Not just that but the phone supports jack connector and micro SD. A truly piece of technology.

Learned a lesson don't buy any phone launched after 2022. Unless it's Linux phone or pro-consumer brands like Murena and Fairphone.

I used to go for Xiaomi phones but I stopped because I had too many issues with the OS. The amount of times it would close an app almost as soon as it leaves the screen was too much, tried every setting ever to fix until I just starting doing 2FA with a floating/split screen.

8 years ago the OS was one of the best, 3 years ago it was one of the worst, not sure how it is now.

It's worse every day, I also had good experience like 8 years ago, if I'm not wrong it was MIUI 12. Xiaomi renamed it to HyperOS a few years ago and it's terrible.

I already knew it was garbage but after I put my hands on a OneUI smartphone I got sure that Xiaomi OS is probably the worst.

I bought the Poco F1, which i think was the first with a internal heatpipe back then? Well, geared at gamers. Still was fairly powerful 7 years later when it broke. So, there's that at least.

What app are you using to log the requests?

[–] Wispy2891@lemmy.world 2 points 5 days ago (1 children)

What happened about the bootloader? Afaik there's "only" a 7 days waiting time but that is to be done only once, if the serial number is tied to the Xiaomi account that makes the request, the next bootloader unlock has no waiting time.

And devices that run a ROM for the Chinese market only accept a bootloader unlock request from a Chinese IP address

[–] CodenameDarlen@lemmy.world 5 points 5 days ago* (last edited 4 days ago) (1 children)

No, devices from China region are gone completely locked forever I guess. Chinese government made a new law that makes Chinese manufacturers enforce locking any system modification.

For non-Chinese using recent OS (HyperOS) you need to apply for unlock and it has a global quota of 2000 devices per day. People need to time it exactly 00:00 Benjin time to send a request to server to MAYBE get permission for unlocking. Some people made scripts that send requests automatically and still very few people are able to unlock it. Most of the time you'll get "quota limit reached", and it's only possible to try once a day.

I tried for 4 days and gave up.

Chinese government decision:

  1. Manufacturers should improve the authority management mechanism for mobile smart terminals, improve the security of the operating system, and take technical and management measures to prevent the replacement of the operating system and the installation of application software in the product circulation link.

This is the main thread about it: https://xdaforums.com/t/how-to-unlock-bootloader-on-xiaomi-hyperos-all-devices-except-cn.4654009/

The 7 days unlock process (which I did) is only valid for old OS versions like MIUI 14 (Not HyperOS). My second hand phone comes with MIUI 14 so it was simple to be done.

Wow good to know, that means Xiaomi is dead for me now.

2000 devices globally is a ridiculously low number
