Ok, I don't know if I have the worst luck ever with Apple products but I must be close. Here goes the problem:
A few months ago, an iPad 4 was - out of the blue - stuck in a boot loop. After a few attempts to reboot it, it turned on, only to skip straight to the Apple logo. After being in the boot loop for a few minutes, it didn't turn on anymore. I plugged it into iTunes: Recovery mode. Weird. Ok, let's try to restore it (I'd lose iOS 8, but I just want it to work). Error 4050. I tried on a different computer with a different cable: error 4050. The screen never turned on before, during or after the restore.
Well, nevermind, I'll eventually take it to Apple - task for which I have to travel to another country -, let's use the other iPad 4 (my family uses both of them, not me).
Fast forward a few months to two days ago: The other iPad, after being on for a few seconds, had a weird black "overlay" vertically travel the screen, after the "curtain" reached the bottom, it shut off. I rebooted it, the same thing happened 7, 8, 9 times. Then, it wouldn't turn on anymore. Ok, let's plug it into iTunes. Recovery mode. Wouldn't exit, the screen wouldn't respond. Again. A restore attempt: error 4050. Different cable, different computer: error 4050. The screen, again, never turned on anymore. Contacted Apple, the usual: might not be software, bring it in for inspection. I'm not in a country with an Apple Store, so I have to wait until I travel. Both iPads are stuck in a drawer, "broken".
Has this happened to anyone, and went to the Apple Store? What did they tell you? Thanks everyone.

Can’t say anything about the second one, but here’s what I would try for the first device. Make sure you have a good cable and an up to date iTunes on computer. Now, DFU that bad boy like 6-8 times. Just keep doing it even when you get errors. Apple’s error code descriptions are vague at best, but I’ve personally gotten multiple iPads through various errors by just continual DFUs. I don’t have an answer on why or how it will eventually work, but a theory is that parts of the flash storage where it is writing the OS are getting bad sectors, and maybe with continual attempts to restore and write the OS, the sectors are getting marked as bad for the next DFU attempt. Could be entirely wrong, but I think it’s worth a shot.

For the second device, without seeing it, your description sounds like a hardware issue.

I'll try that, thanks. I figure that anything is worth trying, as the Apple website quotes $300 for the repair. For 329, you can buy the iPad 2018. It would be absolutely pointless to pay to repair this, so I'll try. Thanks again.

It failed, oddly, with error 4014 every single time, around 8 times. It's gone. I'll try the other one, but I'm not hopeful. Apple has that error in the same category as the 4050 which showed up earlier. Also oddly, my Mac with a slightly outdated iTunes version restored it - and failed. A windows computer with the newest iTunes version didn't even recognise the iPad.
The second one failed, too.
