K3 note black screen wont boot

Hi, So after numerous attempts to root this phone, tried root junkies guide, all being not succsesful, i used spf tools to try and flash CWM custom recovery. I got a green succsesful and then tried to boot into recovery. The phone vibrates once and then just nothing. The red charge light comes on when plugged in but my pc unable to recognize device as it keeps starting up and shutting down all the time i guess all i hear is that windows plug in plug out sound the whole time. I was running the stable 1524 rom.... pls help
[K3 Note Q&A, Help & Troubleshooting] Marg3latu:
I fcked up

This is a sad story but I still hope it will end well.

So I was using the official 1527 ROM, rooted and removed some of the Lenovo apps, everything was working great. But then I noticed they released a new version, 1528 and thought I should give that a try via OTA. I have downloaded the updated and confirmed that I wanted to update, updated successfully, but, of course, the root was gone and also google services was crashing. So the first thing I tried was a simple restart, just to see if google services will keep crashing.

To my surprise after booting the screen was not responding anymore. Not being able to re-enable USB debugging, I searched for hard reset options, I turned off the phone and started it back on pressing VOL UP and the Power button and going into a chinese menu I erased the EMMC. MY phone now boots and ends up in the first configuration menu (the one that asks for the language: EN/CN) but the screen still won't respond to touching.

Any suggestions are welcome.

I used the cwm posted here, but after following the steps in my post you should be able to flash any recovery that is meant for this phone (look on the official lenovo k3 note reddit wiki). I also used gapps 5.0 minimal and they worked ok. For me it's the worst decision I've ever made that I have updated to 1527. Maxaudio stopped working and there are bugs everywhere. Can't wait for someone to post a link to the official india row rom version. If you or anyone else has it please post it for every stock-rom lover that uses this phone :)

You just saved me from flashing 1528 and bricking the phone like you did. Latest official DEV roms are terrible and EVERYONE should avoid them. As of your problem, sorry I can't help you as I'm not a very experienced about that kind of problems. Hope you'll find a way to recover it, and if successful post the solution here for anyone who encounters the same problem.

Hello guys , I am new here and totally lost ,

I got this phone from a very popular Chinese retailer(GearBest)

the phone unfortunately has lots of bloatware(AVG, DU SPEEDBOOSTER, DU BATTERY SAVER and malwares that show ads in youtube(youtube can't be updated too) app and fake twitter app its named "twiter" in the package)

where to start? I need to take the risk and flash the indian official verson and stay clean and be supported BY OTA from Lenovo

I have no idea what recovery is installed , and what to do , I have never flashed a firmware before

I need someone to direct me to the correct lane , thanks to everyone

3) Flashed CWM recovery with SPtools.

the key is to do this - Press and hold the Volume Down Button + Volume Up Button + Power Button.

When you see the Boot Screen, Release the Power Button but keep the Volume Buttons pressed until you see the Recovery Screen.

I got Chinese menu in the CWM, I could read the word ZIP in one of the options and from there I installed the UPDATE SU and rebooted with the top menu option, I googled Reboot for Chinese and compared the script with the menu and rebooted. I have not installed custom ROM, I just removed bloat ware and installed google launcher, the lenovo launched has not app drawer.

So i'm still trying to make a flashable recovery zip from a Nandroid backup, now with the new lollipop .dat files it's more complicated.

So for now i leave you here my TWRP backup (system and boot only):

K50a40_S114_150618_ROW

It's untouched stock, latest OTA, every app updated and rooted!

The first boot takes a long time optimizing all the apps...

This way nobody else has to flash the entire rom via SP Flashtools and go through all the troubles we have seen.

Just enter recovery, do wipes, restore, reboot, Done!

It thanks if i helped you;)

Does OTA update still work if ROW ROM is rooted?

I'm looking for a ROM which has official OTA and could be rooted?

Or is it any method to unroot a ROW ROM? I only need root for restore all my apps using TitaniumBackup (tons of configuration which I don't want to do again) and after that I don't need root any more.
[K3 Note Q&A, Help & Troubleshooting] hackerpower:
Of course it works, but you have to flash stock recovery to be able to flash the OTA update downloaded and after it's flashed you will also lose root acess.

Everytime you OTA update, you'll have to flash custom recovery and then root again.

Without "data" backup after you restore, it will be as you just installed the rom, every setting gone, including system settings. Not the best choice...

Flash stock rom via SP Flashtools, use rom in 1st post.

I think i will try the 2nd option, i tried the 1st one a long time without luck, just need to ask permission from mods.

The bugs that Limonchelo has, the indian A40 rom also has them. The only difference is that indian rom has functional OTA updates.

Then there's little differences, Indian rom has less free RAM, different quick setting toggles, etc...

Try both and choose.

Hello all,

This is my first post here and I am facing an issue with my Lenovo K3 note. Please help me with it.

I bought Lenovo k3 note a week ago online here in India. Evrything is great with this phone. The only issue I am facing is it doesn't give any Notifications for any app!!!! I have installed numerous online shopping apps but K3 never give me any new events' notifications from these apps. Moreover it doesn't even give any new incoming email notification from Gmail too!!!! I am a noob in using Android phones. This is my first ever Android phone so I don't have much idea about setting it up. But some of my friends said that all these notifications are enabled by default in all the phones. I have tinkered with my K3 Note's settings related to notifications but to no avail. Might be possible that I am missing out some mandatory settings. So please, friends, help me out in this weird situation.
