It stores the OTA update.zip in /data/data/com.lenovo.ota somewhere (you need to be rooted to see it)... I'm just in the process of starting over from scratch, so I'll update when I'm done to say exactly where.. I wasn't able to flash that from custom recovery, though... It was showing a wrong "build fingerprint" or something like that?

That's a dev rom, not a stable rom. Also, it's the Chinese dev rom, so only has English and Chinese for languages. And is full of Chinese bloatware. And doesn't have Google Apps (Play Store, etc) installed, so you have to flash a custom recovery and a separate GApps package.

No matter what I did, I wasn't able to get it working. And the only way to get back the stock recovery is to do a full flash of the original rom in SP Flash tools.

As for fully automatic updating, I guess you're right.

I tried something else. After the OTA update had been downloaded, I located the zip file and copied it elsewhere.

Then I rebooted into TWRP and tried to install it, but without succes. 'Error executing updater binary in zip' is what I got. Since my device is rooted, I can imagine that this is causing some issues (not sure if this is the only issue for the method I've tried). Maybe I'll try to unroot and retry installing the update.

In case people want to try it themselves, here's the location where the OTA is stored after downloading: 'data/data/com.lenovo.ota'. You'll need a 3rd party explorer tool like Root Explorer to acces Android's complete file system.
[K3 Note Q&A, Help & Troubleshooting] hackerpower:
That is not a rom, it's an update, you already have to have the original chinese rom and a custom recovery to flash that update on top of it. If you try to flash it alone in the end it will say that you have no OS.

The rest has already been said.

In order for the update to download and install, you have to have stock recovery, fully functioning system updates and be unrooted.

Check the index thread in my sig, any doubts PM me.

Until now the best i've found was limonchelo novamod and yes you can flash roms meant for the K50-t5 and vice versa.
[K3 Note Q&A, Help & Troubleshooting] WearySky:
Yeah, I tried that too. The update does some kind of fingerprint check, and root/custom recovery seems to trigger that. I imagine there'd be a way to dig into the update zip file to change the fingerprint that it's looking for in the script, but I didn't get around to trying that since I had already gone back to stock unrooted to start from scratch.

re insert the battery

I had same invalid scatter file with latest vibeui 2.5 rom. So I downloaded it onto the phone and flashed it with CWM. It seems to have worked fine.

So I am running latest vibeui 2.5 rom (1523) from lenovo.

My problem now is that I need to root this ROM to uninstall apps I don't want, and to install google apps. However when I use the same method (first post in the "official" thread) to flash the CWM recovery image, it flashes ok but when I reboot to recovery the Lenovo Recovery always runs instead of CWM.

Can anyone point me in the right direction to correctly flash CWM when running the latest stock lenovo vibeui 2.5 ROM?

[K3 Note Q&A, Help & Troubleshooting] made_in_nz:
ok so I figured out how to reboot into CWM after flashing stock lenovo vibeui2.5 ROM.

I used was using the method in the first post from kangel to flash CWM, but every time I was rebooting it would either:

1. using Vol-up + Vol-down + power - it would just reboot the lenovo recovery.

2. removing battery while in fastboot, then doing the Vol-up + Vol-down + power would just boot the phone.

The trick to get it to boot into CWM was to:

1. remove the battery while in fastboot (ie straight after CWM is flashed to phone),

2. put battery back in.

3. press and hold power button until it vibrates. As soon as it vibrates, keep holding power button and:

4. press and hold vol-up and vol-down (while still holding power button).

This is the only way i can get CWM recovery to boot after flashing stock lenovo vibeUI 2.5 rom.

question

the phones with mediatek mt6752 and mali 760 mp2 gpu preforming well in gaming but why not the lenovo k3 note? it is same ? does any one have any idea how to reduce lag in asphalt 8?
[K3 Note Q&A, Help & Troubleshooting] dude_creative:
There is a solution for this. But may not be accurate. Lenovo throttles the CPU heavily after around 5mins of playing asphalt to keep the temperature below 50C.

So rename the /system/etc/.tp/thermal.conf to thermal.conf.bak - now no lags like 15fps (but framerate is still 20-25 because of the Full hd screen).

Next thing to do is install Gl tools and do a Texture 0.5x - and fake Mali T628 GPU. Now all perfect and continuous 30fps.

I heard The recent update s117 has solved those problems , but not sure how true it is.

Help

Hi guys

great thread.. Been reading pages and pages but I am a little confused. I also read Reddit and Whirlpool but I am not sure what to do.

I have a China version of K3 VIBeUI 2.5 1511 (it came in a sealed box from Gear Best and have play store installed)

following root junkies guide I install CWM and Super SU

But where should I go from here.

Ideally I would want a ROW ROM but I am reading that I shouldn't use CWM mod for this and instead use TWRP.

I am hesitant installing another boot loader as I am afraid of a brick. I am not an expert at this thing.

Otherwise Limonchelo seems fine but that's also the same problem right?

Finally maybe I should go with ASOPv4 which I can just install using CWM?

Any advice would be awesome.. Thanks
[K3 Note Q&A, Help & Troubleshooting] WearySky:
Nope. After 10 minutes of CSR Racing, it lags all to hell.

Those are other devices. Lenovo puts a fingerprint check into the OTA zip update script, which causes it to fail if you try to flash it with a custom recovery. I haven't been able to manually flash an OTA update and get it to work after rooting/custom recovery. Even unrooting and flashing the stock recovery back, it still fails.

One of the nice things about flashing with SP Flash tools is that it's pretty hard to brick your phone. You might lose your data accidentally (I've accidentally wiped out my userdata more times than I care to admit), but rarely will you be in a state where you can't re-flash.

If you're going to flash the ROW ROM, you're better off just flashing it with SP Flash tools. Clean install, good to go.
[K3 Note Q&A, Help & Troubleshooting] rydraj:
Does anyone know why the command "fastboot boot name_of_recovery.img" doesn't work for this device ? If it did, it would solve the whole issue as we could just boot from custom recovery to root but always go back to stock recovery so that OTA works fine.
