Xiaomi Mi 11/Pro/Ultra Wifi dead

[Martin | Mi 11]

I've seen that I'm not the only one facing this issue. So I want to open a thread so we can discuss how we are solving the problem. Here's how it looks if you have the issue:

The issue is caused by the heat of the Snapdragon 888 and poor thermal handling, which causes the solder of the Wifi chip to melt

Xiaomi knows this and has extended the warranty of these phones by 6 months for Chinese phones. But in order to redeem the extra warranty you have to apply for it in the Chinese Mi Community App, which I haven't figured out yet.

If anyone knows what the repair without warranty costs or if you can repair it yourself please comment below

I have a Mi 11.
The WiFi problem also happened to me. Around March of this year.
In September the problem involving the Snapdragon 888 got worse and the phone died completely.

The seller (tradin******hen) asked €300 and about 4 months minimum to replace the motherboard.
I looked for alternatives and almost no repair shop wanted to try the repair.

Fortunately I found an excellent technician in Portugal who did a reballing and solved the problem.
Look into this type of repair.

I've just returned my Mi 11 for this exact issue. Fortunately still under warranty (just). The official diagnosis by the repair facility states that it's an electrical fault on the wifi hardware caused by the battery overheating.

If anyone in the UK has this issue, if your phone is out of warranty, you should still be able to claim free or reduced cost repair for overheat damage as it's inherent to the model and known by the manufacturer (under Consumer Rights - https://www.gov.uk/consumer-protection-rights)

if it was purchased in France and you have proof of purchase check if you're covered under french/european consumer rights. Your warranty is linked to the country of purchase not your country of residence

I guess now my phone is dead. Might need to look into this reball thing

At first my phone "came back to life" but the Wi-Fi failed again but after a new technical intervention everything is ok and functional.

Guys, have the same issue. Bought my 11 Ultra on August 2022, wifi died after a week of usage, lol. In November the onboard sound started to glitch and randomly turn off (what's interesting, both analog and bluetooth headphones still worked fine). Yesterday the device entered a bootloop, and eventually turned off with low battery. Today I've been able to revive it for about an hour (almost enough to get some vital data from it) and then it started to reboot again and finally is stuck in fastboot mode. Did anyone else have any success with reball procedure?

P.S.
My colleague also had Mi 11 Ultra. And it just died a week ago. Love that modern flagship quality.
Once had Mi 3, and it worked fine for five years. Replaced it just because it was obsolete, it's still alive tho.
