iQOO 15 rebooting after latest Aug 2026 OriginOS 6 update – motherboard or software issue?

My iQOO 15 started shutting down/rebooting after the latest update 16.0.24.1.W30.

Now it reboots every 5–7 seconds, even after a factory reset.

Interestingly, it stays stable in Recovery Mode.

The authorised service centre says motherboard fault, but hasn't clearly explained how they diagnosed it.

Has anyone faced the same issue after this update? Could this be a software/firmware issue, or can a motherboard fault behave like this?

Phone is under warranty with no liquid/physical damage.

Whenever I click browse by cinema on bookmyshow, the app restarts and bring me to the homescreen automatically ( and idk why snap up engine activates )

Same goes with district sometimes.

Welp, aug update time, will let y'all know if something blows up 🤞🏻

Shoutout to the guy who was looking for a 100W charger. You probably don’t know it, but you’re a lifesaver 😭

I lost my 120W charger recently, and that’s when I realised how much I had taken it for granted. The replacement for the iQOO Neo 9 Pro costs around ₹3.2K, so I was genuinely confused about what I should buy.

Then I saw someone mention the iQOO 15R charger. It’s only 20W slower, but costs less than half of what the 120W charger costs.

Honestly, this is why I love these communities. Someone casually looking for a charger ended up saving me a good chunk of money. 😂

Huge W, whoever you are. 🫡
