i'm on aosp 5.1 lemonade. i dont use video app. but for notification i might have the solution.

i observed that my device having problem with notification on wifi, but it ok on data. from readings, i can confirm the problem have something to do with android rom handling gcm on ipv6.

quickfix: disable ipv6 on your device. use this app to disable ipv6. i suppose u are rooted. you need to do this on every wifi connection establishment. ipv6 tools

if you want to monitor further, use this app to check if gcm communication is ok. push notification status

enabling ipv6 again will maintain gcm ok status. i dont know why. hope this helps.
[K3 Note General] vonuzu:
Yes. Edit and modify.

Hold Volume + & - then press and hold power button. Once phone vibrates, release power, then volume buttons.

I am having the exact same problem you mentioned.. The notifications on the apps which should notify like WhatsApp don't work on Wi-Fi. And have been observing it closely.. Actually it works for a while like for 30 mins or so but after time passes I see the notifications don't come through and I have to go to the app to get the notifications.. And this problem goes away when I am on mobile data. The notifications work normally and I get it all the time..

And I have observed this WiFi issue on other ROMs as well. I am on Vibe UI dev 1532 and I see notifications don't come through for WhatsApp after many hours.. Initially its okay.. It was on S114_ROW ROM as well.. Limonchello also had the same issue on WiFi.. Hope it gets rectified soon

And thanks bro.. For the solution you gave.. I have installed the app and disabled ipv6 and I find its working fine for now.. I ll check it out and update the post soon if it gets rectified.

Update: Glad to know that notifications issues has been rectified on WiFi using ipv6tools suggested by uan. Now I am able to get the notifications on WiFi even after few hours. I left my phone overnight with WiFi on and I see my notifications were constantly coming through.. Thanks uan!

After flashing it using fastboot just right after doing fastboot reboot as soon as you type it just hold the volume up and down button until you see the recovery screen. And If you are powering it off then hold the volume up and down first then the power button until it vibrates then release the power button holding onto the volume buttons until you see the recovery screen.
[K3 Note General] meangreenie:
Changing wifi sleep settings from 'smart' to 'always on' might help with the notifications.

[K3 Note General] stephendt0:
Having issues with several apps on the VibeUI 1533 ROM... sigh. Examples include Speedtest.net and this Timesheet app. Did a factory reset and then couldn't get past a constant "WLAN has stopped" FC. Grrr...

Can someone please recommend a ROM which is stable. I've tried like 6 different ROMs and they all fail in one way or another. This is getting frustrating :crying:
[K3 Note General] JackSparrow17:
Nice ASOP Rom, but without theme chooser and cant install xposed....And battery life is amazing....
[K3 Note General] shrihari123:
Nah man. That doesn't solve the WiFi notification issue either. The thing that solves is disabling ipv6 suggested by uan. Hope they rectify this on the future update in the officially way.

So to guys who have the notifications don't come through on WiFi issue this can be a solution now. You need rooting privileges. Then download this app ipv6 tool from play store and disable the ipv6. You gotta do it every time you turn on WiFi. This can be a solution for now.

I am on twrp backup of vibe ui 1532 dev ROM and its quite stable and sexy. I like it. Its fast debloated has good sound output without the earphones. Its very stable with rooting privileges as well. One thing I find it lacks. The led notification doesn't work for all the app notifications. It works for only calls messages and few apps which is default there. Otherwise its a very good stable ROM. You can also solve the WiFi notifications issue as I have mentioned in the previous post. Everything is fine and every app is working good. Speedtest.net others you mentioned as well.. I will have this ROM until I find a better ROM in future. The twrp backup is in hackerpower's index thread. Have a nice day!

[K3 Note General] stephendt0:
Silly question I suppose, but is there a way to view notifications on the lock screen? They don't even appear in the status bar. Using the VibeUI 2.8 1529 DEV ROM. I can't believe Lenovo would remove this feature.
[K3 Note General] mickey78:
They messed on that one. You need to install another lock screen...

I can't get the Carbon ROM to work - after setting up the wifi, it gets stuck on 'checking for updates' which I can't skip.

Or you can simply reboot into recovery from recovery a few times.. Either way I guess.

---------- Post added at 08:05 PM ---------- Previous post was at 08:01 PM ----------

I'm on couco's 1529dev. Only way I've gotten it to work is make Google launcher a system app. Most the time it will disappear from app list, but if you then convert it back to a user app it will show up on the launcher list...

---------- Post added at 08:08 PM ---------- Previous post was at 08:05 PM ----------

---------- Post added at 08:15 PM ---------- Previous post was at 08:08 PM ----------

Be careful I did that by using the stock firmware update app on couco's 1528dev ROM by installing stock recovery, it will update. But be careful, once I was on that 1533 I was unable to install custom recovery.. Either by fastboot or sp flash tool. If someone figures it out let me know
[K3 Note General] elrasho:
I'm from the UK, is there a stable ROM that allows all the functions of the phone work? e.g. LED notifications, Google Play store etc...
[K3 Note General] vonuzu:
Yes. Indian ROW rom.
[K3 Note General] elrasho:
Is it called 'K50a40_S112_150610_ROW' ?
[K3 Note General] vonuzu:
Yes or there's updates, s117 and s121. But if you flash it with sp flash tools it will update itself via ota.
[K3 Note General] elrasho:
And they are fully functional in the UK? Will google store work?
[K3 Note General] Kodaro:
Yes it will all work. My led is only green tho.
[K3 Note General] mirchichamu:
Hi all,

I was able to do all the jobs mentioned here with success when the phone was on stock ROM. But yesterday I upgraded the ROM to version VIBEUI_V2.5_1529_5.1063.1_ST_K50-T5 (STABLE VERSION).... Now I repeated the whole process . It says that recovery is installed through command prompt but in fact it isn't. When I reboot in recovery, it shows Lenovo recovery. I installed twice through command prompt but the same result. What could be the reason and how to overcome this? I shall be much thankful in advance. Secondly after doing this procedure, there is no more updater in setting, although it is there in the applications.
[K3 Note General] BILLieve-I-DO:
You'll need to reboot into recovery from recovery a few times in order for it to stick. If you just reboot the stock recovery will still be there.
[K3 Note General] SteveCoops:
Yep I'm using the ROW S121 now on my phone with a Three and an O2 SIM in and it works perfectly.
[K3 Note General] mirchichamu:
Thank you very much for the reply. I rebooted more than ten times but in vain.
[K3 Note General] k@iserex:
If you have flashed custom recovery like TWRP you will need to boot into it. Hold the down and up volume keys then hit reboot on PC. Keep pressed until you see the recovery boot screen, release it and your in. While you are at it, root the phone by flashing SuperSU and recovery will stick. All the the info is available in index thread :) :) ?
[K3 Note General] mirchichamu:
A million thanks. It did the job. I was rebooting normally and restarting in recovery, which was wrong. This time I hold the volumes up and down plus power while hitting the command and it went straight to CWM. Thanks again.

Hi All,

Did someone installed the google camera app ? When done are you able to take a panorama or Sphere picture ? Seems that my accelero/gyro got a deviation... even when i do not move it goes on the left slowly.
[K3 Note General] vonuzu:
I tried the sphere, but i guess we don't have a proper gyro sensor. Its some sort of imitation or a combination of other sensors. See here:
[K3 Note General] mickey78:
That's weird because if I recall, in another ROM (I think it was Limonchelo) the camera app that was integrated had a similar functionality and it worked. But I do have ther same problem with Google's.

SP Flash Tools and TWRP Heads Up !!

Hello Everyone ,

I have this phone with me , i ask everyone to realise that we have a Mediatek Chipset inside ! , SP Flash Tools would work as we all know ,

hence please proceed in first doing a READ BACK ! ,

The File would be of a 16Gb Size ! , This is like an entire Image of your phone , NVRAM Inclusive !...

So Now we can safely proceed in Designing Roms , i see that Root is already out for this device

1) Is there a TWRP Recovery available ? ( If not we need this ready )

[K3 Note General] rob4x4:
You could try this ROM: http://www.movilesdualsim.com/tema/vibeui_s121_visnu_lemonade-18-08-2015.107124/

Its basically stock ROW s121 with xposed and gapps added and no bloatware. I've been using it for a few days and everything works well.

Flashable via TWRP or CWM.

I've installed Google Now launcher over the top so its almost AOSP.
[K3 Note General] vonuzu:
Yes I saw that, but in the comments the users were complaining about the ram..
[K3 Note General] rob4x4:
Everyone likes to complain about something. Depends on how you use the phone. I've got 20 apps open in recent app list and 666 MB of RAM free. Android is designed to use up the ram and free up more as it needs it. I'm not a gamer so can't comment on that. People complaining about Whatsapp notifications not coming through and battery drain too. That all works fine for me. I've switched from Lemonchelo as I found it very laggy and slow. Other people said how good it was.

Guess you'll have to try it the ROM for yourself and see.
[K3 Note General] Bidyadhar:
Guys I am on Vibe 2.81534 latest build.. Sometimes the recent task list doesnt show up at all.. Is it a bug??
[K3 Note General] Scorchgid:
Is English supported as the forum is I'm Spanish?
[K3 Note General] damanrico:
Yes.

I'm also using that ROM, but I'm having the lag at times. It seems when it drops to around 450-500MB of free RAM left, it starts to get laggy. The system itself already uses 1.0-1.2 GB RAM, so it happens quite often.

I also experienced this on other VibeUI ROMs, sadly these ROMs are very RAM hungry and that seems to cause the lag.

I have yet to find a ROM that doens't give me lag, but for now this ROM gives me the least lag and for the rest it works just fine.
[K3 Note General] vonuzu:
If you compare it with the dev versions, is there it less or more lag?

And how about battery life?
[K3 Note General] damanrico:
About the same.

The battery life is also very good for me. The ROM itself is working great for me, the only problem is the known lag issue that pretty much every other ROM also has.

For now I'll be sticking with this ROM, until one day there's a ROM that has no lag at all.

[K3 Note General] neverhood11:
You guys are writing about lags or other problems in different roms.. I`ve been using VIBEUI V2.5 1529 ST for some time now and didn`t experience any lag at all, don`t have any issues, battery life is very good, also gaming is very good. No reason to change the roms for me for the moment.. I use lenovo launcher... I think that some other launchers cause lags..
[K3 Note General] damanrico:
For me the lag isn't just in the launcher. It's everywhere.

It can be in the settings, it can be in the Reddit is fun app, in Chrome, etc. You notice it when you have your screen on but haven't touched the screen for like 5-10 seconds. Then when you start scrolling/swiping you notice lag / sluggish scrolling. If you keep scrolling after the short lag it's smooth, but when you let the phone idle again for 5-10 seconds the lag will occur again when you start scrolling/swiping.

But like I said, for me it only happens when the free RAM drops below ~500MB.

I could give VIBEUI V2.5 1529 ST a shot and see if that one is actually lag free.
[K3 Note General] SteveCoops:
I'm getting a fair bit of lag on ROW S121 - I don't remember having this at all on the original Limonchelo one. WhatsApp especially keeps freezing for up to 5-10 seconds at a time which is really irritating.

[K3 Note General] mirchichamu:
I think you are doing the same mistake which I did. At the last command of rebooting into recovery, you should immediately hold the volume up and down plus power button soon after the device shut down. Otherwise you will end with Lenovo recovery. This is Lenovo recovery what you are showing.

Repeat the command for recovery installation again and at reboot command hold the power plus volume up as well as volume down.
