Congratulations  ?? for your working Lenovo K8 Note this fix is 100%  working  as many have already confirmed to me on YouTube. By the way you can up with new method of baking the motherboard on Iron box?, one of my subscriber on YouTube heated his motherboard by keeping it 25cm away from the stove flame and his K8 note started working. Though I don't recommend this method as it's very dangerous and he himself in the process forgot to remove the selfie camera and eventually burnt it completely. So now he has a working Lenovo K8 note but without a selfie camera.....by the way you can easily buy a selfie camera online for Ra 1300.

Re: Lenovo K8 Note - Auto Restart issue/Boot Loop (SOLVED - Bake the Motherboard inside the Oven)

Hello... Tried it out in the first half today..

Initial comments:

1. Phone boots

2. 24 apps updated from PlayStore with temp of phone as it used to be before bootloop issue i.e. hot..

3. AnTuTu Benchark's Stress test completed while I type this comment. => Test runtime: 15mins, Phone temperature: 66°C on the run.

Seems some CPU Thermal sensor is blown or service couldn't read it, as after sometime during the test temperature stopped updating and was shown 0°C...Even after reboot it stays as 0°C, so no ways to know the temperature anymore.. (Anyone can confirm, it ever worked as I can't remember)

 

Trying 3DMark now, whole purpose is to see if it bootloops or not...

 

Procedure I followed from the steps given, however I couldn't attain the temperature of 230°C as my IFB appliance didn't have any temperature beyond 200°C...

 

Steps I followed:

1. Pre-Heat in CONVECTION mode only (Not any other mode or mixed mode)  at temperature 200°C for 5mins

2. Once pre-heat completes, place the motherboard on the glass turn top for 10mins

3. Let it cool..

 

Then I realized I did't remove the heat dissipation covers (Shields)..

 

4. Removed those covers

5. Repeated step 1, 2 and 3

6. Added Thermal compound on the chips, covers and also above covers..

End of story...

 

Ok, bored.. Stopped the test for 3DMark.. It scored around 1030. and ran for about 5mins..

 

 

Thanks bro... Hope it continues to work...

Re: Lenovo K8 Note - Auto Restart issue/Boot Loop

Hello Lenovo Support Team,

I am facing boot loop issue on my Lenovo K8 note, there is no water damage or any other reason because of which it started.
It all just started suddenly.
I like this phone very much and I want this to get fixed. 
I had taken my phone to Lenovo care center, but they just returned it saying Motherboard is damaged.
They tried flashing it but issue is still the same.

Below are the troubleshooting steps taken so far-

1) Factory reset
2) Hard reset
3) Flash

IMEI No. 864510030253655 / 864510030362738

Please provide solution for this issue. I am a happy customer so far and hopes to maintain the same.
My Mobile no. +918421166344.
