[K3 Note Q&A, Help & Troubleshooting] ibidem:
Hi. Unfortunately, my K3 Note cannot get up after my tries to root it. Moreover, it has now no system at all and Chinese recovery. Would somebody be so kind and guide me to undo to the phase it had a working system at least?
[K3 Note Q&A, Help & Troubleshooting] dreambo:
If it can be recognized by SPFlashTool, no warry :)

only find a rom flashable with SPFlashTool (not a a zip flashable only with a recovery) : http://4pda.ru/forum/index.php?showtopic=659110&st=0#entry39545579 (choose the link after flashtool, I can not read Russian too)

the rom's name is : K50-T5_USR_ST1511_5.444.1_1503111505-Lang-EKL2.zip

Very Important : for SPFlashTool, you must check the option "DL DA all with checksum"

the recovery that I give you the link in my post is in English and china, just choose English on startup.
[K3 Note Q&A, Help & Troubleshooting] XPSprobs:
All right, thanks for the help. Could you please give some steps as what I should do exactly? I'm a bit weary of ticking the wrong options now ;)
[K3 Note Q&A, Help & Troubleshooting] dreambo:
1/ download the rom and unzip it in a folder (because it is flashable by SPFlashTool only, not a zip update flashable within the recovery)

2/ open with SPFlashTool the scatter in the rom folder

3/ In the options of SPFlashTool, check the option "DL DA All checksum"

4/ completely power off the phone and unplug it from USB

5/ In SPFlashTool, click on "download"

6/ Connect the phone to the computer via the USB cable : it must be detected by SPFlashTool and the flash begin

If you have an error, instead of "download" on step 5/ do a "firmware update" but never "format all & download"

If you are not familiar with SPFlashTool and its drivers, please search for tutorials, it is not specific to lenovo k3 note, all Chinese phones uses the same soft.
[K3 Note Q&A, Help & Troubleshooting] XPSprobs:
First of all, I would like to express my sincerest gratitude for helping me.

On both occasions (using the option 'download' and 'firmware update') I get the following error.

Any suggestions on how I might resolve this?
[K3 Note Q&A, Help & Troubleshooting] Armacryss:
I think dreambo will be more helpful but, as far as I know, I had the same problem when my drivers were not OK.

The russian link offers a driver + SPFlashTools... maybe you should try : 4pda.ru/forum/dl/post/6169412/LenovoUsbDriver_autorun_1.0.9.zip

Just add "http"... I don't have the rights to post link yet.
[K3 Note Q&A, Help & Troubleshooting] XPSprobs:
Hmm... it used to work though. I also got another driver from an earlier link, which is called MTK_UsbDriver_autorun_1.0.14_internal

When using the link I get a 404 error (I assume). Here is the direct link to the mentioned driver for other people needing it: https://mega.co.nz/#!JwxjTTzT!Re4wDq9yyESAL_ELST4-p5beIZnaKbdO7dMfy8dHrlA

It still doesn't work, even with the driver kindly provided.

Which system apps should be removed?

I'm afraif of damaging OS in the device.
[K3 Note Q&A, Help & Troubleshooting] Armacryss:
Basically, I ran ESET and removed the stuff that ticked it off.

For me, it was Twitter and User Experience (both trojan).

Since I used ESET, I also removed the other antivirus already installed.

I had a couple of warning but nothing since then.

Hope it helps...

[K3 Note Q&A, Help & Troubleshooting] MONA RIZA®:
I tried to uninstall the unwanted apps using the "system app remover) but it leaves some trash after the removal. So i didn't like it.

Just tried Titanium Backup to uninstall those apps. But TBP is giving a error message like "APK not found"

So I frozed the apps. Antivirus, Boyaa Poker, Clean Master, Battery Saver, Speed Booster, I Love Wallpaper, Safe Search, Twitter. Only I could delete MaxxAudio and a chinese crap app...

The real question is; is it okay to freeze apps with Titanium Backup? Does it matter removing or freezing?

Maybe an obvious question, but have you tried using a different VPN?

[K3 Note Q&A, Help & Troubleshooting] dreambo:
Try to use the latest version of SPFlashTool : http://mtk2000.ucoz.ru/bbk/SPW504.rar

Or this one : http://www.needrom.com/wp-content/uploads/2015/04/SP_Flash_Tool_Windows_v5.1512.00.zip
[K3 Note Q&A, Help & Troubleshooting] XPSprobs:
That... worked. Wow. That's so incredibly basic. I've downloaded flashtool very recently so it didn't look like a proplem.

It's downloading now, we'll see if I've celebrated to early.

Anyway, thank you so much! If this was reddit I'd have given you gold, but unfortunately it isn't ;)

Edit: it gave a 'download ok' and the phone buzzed the first time I turned it on, but otherwise doesn't seem to be doing much. I do have a charging LED now, which is an improvement. Trying to turn it on again doesn't yield any results.

I'll leave it charging for the night and try taking out the battery tomorrow morning, we'll see what happens.

Again, thanks a lot for the help so far.

Edit 2: It's giving a short buzz every few minutes now...

Edit 3: When I shine a lamp on it I can see the "Lenovo Powered by ANDROID" logos. The backlight seems to be the only part missing now. I have full confidence that it'll be working by morning when it has repented all its sins and rethought its life.
[K3 Note Q&A, Help & Troubleshooting] dreambo:
Have you cheched in the Options the checkbox : "DA DL all with chechsum" ??
[K3 Note Q&A, Help & Troubleshooting] XPSprobs:
I thought I had, but obviously installing the newer version would mess with that. Thanks, trying again.

Edit: It's all working now, but without root and with tonnes of bloatware. I'll try rooting it again then ;)

Wow, this has only gotten worse. It's trying to continuously install browsers and I'm getting ads on my homescreen. D: Lemme just get that root working real quick...
[K3 Note Q&A, Help & Troubleshooting] XPSprobs:
A little update to my adventure. The best way to root seems to me the one dreambo has posted, but with a few tweaks. The Gapps package he posted is no longer available. You can't just pull any gapps from the web as this is a 64-bit phone. Link updated.

Here's the way that I think works best:

1. Download the recovery, ROM, Gapps, superSU and the USB driver.

2. Meanwhile, connect your phone to your PC and make a new folder on your phone. Give it an easily recogniseable name and put the rom, gapps and superSU in it when it's all finished downloading (root folder most likely won't work).

3. Install the driver.

4. Download the latest version of SPflashtool.

5. Unzip the recovery folder you downloaded earlier while the download's going on in the background

6. Open flashtool, go to options, then download and check the DA DL all with checksum option

7. Click scatter-loading, browse to the recovery folder and select the scatter file

8. Click download and plug in your (turned off) phone, it should start downloading, and you'll get a 'download OK' window.

9. Close the download OK window and boot into recovery (press the on button and keep holding it down, when you feel a buzz, press the volume up and down buttons and keep holding them down until the recovery opens)

10. Select install zip from SDcard and install the files in this order: 1. ROM, 2. SuperSU, 3. Gapps

11. Go back to the main menu and reboot system

Your phone should be up and running :good:

Small note: you still can't disable or uninstall apps from the settings. You are rooted though, just download system app remover to your phone and you'll be able to remove all the bloatware.

The icons will remain in your app drawer/homesceen, a reboot fixes this.

One problem that I have with this phone is that the battery gets low fast, even with the phone in standby , this is the only thing I dont like in the K3 note, I was thiking that maybe a software update would resolve this.

If someone had a clue how to fix that, i would appreciate.

Thanks.
[K3 Note Q&A, Help & Troubleshooting] goose25:
Yeah, I am having the same issue. The battery isn't lasting a whole day with any usage.

Also, there seems to be a memory leak somewhere, as I am always sitting on roughly 300mb unused ram.

Can't wait for a stable cm12 or slim rom for this phone...
[K3 Note Q&A, Help & Troubleshooting] smms1973:
Ok , It seams that this phone was made by Lenovo for China only, and some company's are altering the original firmware to sell it on the international market, so the altered firmware is not working very well and like in my case it has a Trojan.

So it seams to me that a way of solving this problems is put the original ROM in the phone

my question is if it is possible to load the phone with the original ROM and where can I get that?

Thanks
[K3 Note Q&A, Help & Troubleshooting] smms73:
Ignore my question on the previous post :o

After reading better the thread I think I can change the rom.

Bro just install the official Rom of Leonovo vlwhich is 1518 has shown the picture every problem in my K3 note has been solved by installing this Rom. Even the battery life of my phone is increased alot. But still VPN and 4g are not working in my K3 may be some problem in the phone itself beside that every thing is working fine in my k3 note now after installing ROM version 1518. :o
[K3 Note Q&A, Help & Troubleshooting] Armacryss:
It looks like you can also install the "VIBEUI_V2.5_1519_7.113.1_DEV_K50-T5" (using the link provided by dreambo on the first page of this topic).
[K3 Note Q&A, Help & Troubleshooting] itzikd1:
did you try puting the sim in the other slot?

did you try puting a diffrent sim (from a friend) in phone?

or puting the sim in a diffrent phone and see if 4g works (might be a sim issu)?

did you check sim setting at bottom of "settings" in "sim mangment"

when going into mobile network "4g" is with a V?

did you check if you maybe need to put a V by "roaming" option (check with cellular company)

setting -->mobile network -->operator selection -->serach network - wait 60 seconds and send us a screenshoot of what you see there

hope any of this tips above help.

[K3 Note Q&A, Help & Troubleshooting] asif3366:
Yes I checked every possible way and I am using two sims available in my country both support 4g FDD band 1800 MHz has lenovo k3 note supports 1800 MHz FDD band. Also I was using the same sim in my samsung S4 and 4G was working fine in my Samsung s4. Most likely Lenovo k3 note does not support 4g FDD or K3 note just supports TTD 4g not FDD 4g may be that's why 4g is not working in my K3 note. But 4g is not much important for me has I need VPN to work in my K3 note bcuz I use VPN for VoIP apps and calls has VoIP calls are blocked here in UAE the country I live. So without VPN I can't use skype, Viber, WhatsApp voice call etc. Thats why I want VPN in my k3 note and I don't know why such a monster phone like lenovo k3 note is not supporting VPN or may lenovo itself have blocked VPN service in k3 note has is it illegal to use VPN in China or its just a bug which is in ROM :confused:
[K3 Note Q&A, Help & Troubleshooting] smms73:
Thanks, today I have installed the version 1519 let's see how it performs, it feels better than before.

Hope you can get your problem solve, have you check the 4G frequency in your country?

I think the k3 note doesn't have the 800Mhz band.
[K3 Note Q&A, Help & Troubleshooting] XPSprobs:
As I said, I haven't been able to get a VPN working either, so it might be a phone issue. I don't know what your use case is, but my solution would be to just use skype on your PC... Not really a solution, but I don't think there's anything else to do other than waiting for a custom ROM that does support it.

On another note: have any of you gotten an SD card to work? I've tried formatting it as both exFAT and NTFS, but with either option it gives me the 'blank SD card or unsupported file system' error, after which it wants to format the SD card. Problem is, it formats it to universal file system hierarchy (or something, can't remember exactly) which spotify can't use... Is it just my phone or does this phone in general not support the most basic and universal file systems...?
[K3 Note Q&A, Help & Troubleshooting] smms73:
This phone only supports a maximum of 32GB SD card, I have try a 64Gb and didn't work, ntfs also don't work, I think I have my card formated with exfat
[K3 Note Q&A, Help & Troubleshooting] XPSprobs:
Hmm... that could indeed be it. Thanks for the suggestion, I'll try looking into that.
[K3 Note Q&A, Help & Troubleshooting] asif3366:
Bro why should I use Skype and other VoIP apps on PC bcuz I am still using Samsung s4 has my spare phone beside lenovo k3 note currently has my primary phone which disappointed me a lot bcuz of VPN and 4G not working in my K3 Note. Has on my Samsung s4 every thing is working fine has I get internet speed of 50+ mega bits every where in 4g connection plus VPN connects like a charm or I can say like piece of a cake and never had any issue with 4G and VPN on my Samsung S4 but it is lenovo k3 note which is pissing off my mode with many problems like VPN,4G etc. That's why we should never buy phones from China every phone will have a problem like the one I am currently facing on my K3 note. Anyways beside VPN and 4G problem I am using a 32 GB SD card on my k3 note and its working fine has picture uploaded below. Now I think only solution for 4g or at least VPN will only be solved by a custom made ROM like from cyanogenmod, miui or colors os etc can only fix this problems. Now I thing the problems of 4g and VPN not working on K3 note most likely would be bcuz of official Lenovo k3 note ROM which lenovo itself have blocked this services like VPN and FDD 4g to make it usable in China itself. :confused:
[K3 Note Q&A, Help & Troubleshooting] XPSprobs:
Indeed, a custom ROM would most likely fix your problem.

Hi asif, when you flashed the latest official ROM, what apps came preinstalled? And is performance significantly better?

What about 4g is that also working for you with this ROM bcuz for me after installing this ROM 4g is the only problem I am facing currently :p
[K3 Note Q&A, Help & Troubleshooting] XPSprobs:
I don't have a 4G plan (yet), but you should check the 4G bands your provider supports. This phone uses LTE bands: 1 (2100MHz), 3 (1800MHz), 7 (2600MHz), 38 (2600MHz), 39 (1900MHz), 40 (2300MHz). You'll be able to recieve 4G coverage if your provider supports either one of those bands in your region. If they don't, you can only fix it by getting a different phone :/
