i have the same problem.
i suspect the rooting process by flashing the supersu.zip is the culprit. maybe it has delete some important system file.
even after do unroot and clean system file also fail....
i think the only way is to flash using sp tools.
sadly my pc is kaput... Anyone live near seremban?

Do it manualy. U can get the s121 rom from last few page here.

Also download from here fail too. From ota also fail..might be need to install full rom s121. Got any link?

Funny thing about this phone's rom. Everybody is making their own rom, but nobody want to perfect it.

China Develope rom but loaded with bloatware. Other custom rom i dont know.
Row rom a bit heavy on battery, i think no big different between China rom.

I detected a strange thing with the K3N. Today left the phone in the car and it got a bit hot. After that I found that the wi-fi does not detect any signals unless I am VERY near the wi-fi hub.

I switched off the phone to let it cool down a bit. Powered on and everything back to normal. Anyone else encountered this problem?

Overheated.....is it under the hot sun? Today really very hot
Beware....electronics device can stand up to 134 degree celcius but li-ion battery can stand up to 65 degree celcius and will swell.....may cause explosion.
Please dont leave any li-ion or li-po battery in your car.....very risky.
Our K3N battery is Li-ion polymer.

I only tested limonchelo rom n has been happy with it
I do not faced so many issues reported even in stock rom
Phone performs well n battery life easily I could get 4-5 hours SOT

Can share link to aliexpress vendor?. I want to get a spare yellow. But I see all listings don't have heat pad inside.

Aliexpress
Before buying please ask the seller to confirm that it comes with the heat pad.
I bought black color from different seller....no heat pad but cheaper, yellow and white got heat pad.

P/S: Use your phone apps [aliexpress apps] scan the barcode on PC to get more discount.

Will do. Tq

I think cheapest way to buy are still on Lazada platform or 11street?

Most of these ROMs are ported ROMs with very minimal modification to the source.

It's not easy to make changes to source. Also, Lenovo only released the source for the India ROM and i dont think it's the latest. There's no git to grab sources from.

e.g.
I changed the resolution from 1920x1080 to 1280x720 for performance and some battery gains.
However, the touch buttons (menu, home, back) are now no longer working. This is because the touch buttons are part of the touch screen and as such are coded to work with the 1920x1080 resolution.

I went through the India ROM source and saw that there are a lot of touchscreen driver source codes. Dont know which one to modify.

Anyhow, here is the Antutu bench result on 720p.

Hi
Can someone translate this for me?
