I have replaced successfully the touch screen as per the instruction given. Now mobile is working perfectly but unfortunately there is no signal. so not able to make calls and changed SIM cards for my satisfaction. I have done flashing with latest ROM available in MIUI website, but nothing works.

Please help me to fix the problem.

I have a problem with gyroscope and accelerometer. It all started when I dropped my phone on the floor, broke the screen and changed it by myself. This problem was fixed, but I had to look inside my phone few times more to change some parts killed during screen change. It was fully functioning for some time(maybe month), but then screen stopped rotating, compass stopped..other words gyroscope and accelerometer died. After some experiments I noticed, that it starts working when my phone is uncovered till the motherboard. But as soon as I cover the motherboard and push on the cover(as screws do) gyroscope stops. Gyroscope chip soldered to the board good(tried to heat it) and the contact on the other side is also good. I can't understand what's happened because gyroscope stops when I push on the connector, so it could be bad contact, but also other problem caused by board deflection, and also gyroscope stops working when I push on the board near the chip(from the other side), once again board deflection or bad contact caused by board deflection. Last time I opened my Mi3 sensor stopped working in any conditions. Please find attached photos of 330DC gyroscope chip and the connector on the other side

If anybody met such problems or has any idea what to do - I kindly ask for help

Any tip or tutorial to change it?

How should I remove the metal piece that cover the SIM pins? Just unsoldering?

Thanks!

My phone goes off and when i try to charge it, it was just red light blinking.

Can't be open and just dead.

But I'm too desperate to give up. I tried to revive my battery using my magnetic charger.

I mean i charged the battery by using magnetic charger. Not through the usb port.

It works. It opens. I connected the charger while it was opening. And it works!

The battery is working, and charging.

The system is fine, everything is working fine.

I can use the phone well and play well.

I thought it was fixed but no.

As soon i disconnect the charger, it can't be charged again. And the battery drains in less than an hour.

It works everytime i disconnect the battery, open it in before 10sec has passed. And connect the charger before it starts up.

Take note: it is still broken, when i restart the phone it wont work again and again. Just red light blinking.

What do you guys think the problem is?

Tbh my battery is really dead, i mean it normally drains from 100 to 0 in less than an hour.

But now it wont charge anymore without doing this trick.

I have replaced the display once and now I had the minor crack and my display, again, not reacting to my touch.

I am tired of this prone to die display and I am seeking insight on what is the weakness of this display, why is it so easy to crack and dies?
