I've used your TWRP recovery which asked if I wanted to make it non read only which I agreed too. Things went wrong after I agreed to that. I think that's where the root of this issue was. However I reflashed it with SPFtools it didn't solve the issue and I am still unable to install a rom through recovery

I've gone back and forth between that one and the clockwork mod in the main K3 thread.

none of them are able to install roms. I'm still stuck I thought I figured it but it seems I haven't

"flashed a recovery that's not meant for your phone. "

I've only used recoveries that were on these threads.
[K3 Note Q&A, Help & Troubleshooting] badbug:
Hi all. A noob here. I bought the phone from aliexpress and it came with the vibeui Chinese version. It was unusable in Finland as it did not have any gapps etc. I managed to flash a ROI ROM successfully using flash tool. But I have two problems. It constantly thinks the SIM is in roaming so keeps giving data roaming warnings. Also data connection drops all the time. wifi is quite fine. Also, it doesn't recognise 4G et all. I have saunalahti which has FDD 4g and should give around 50mbps. But the phone only recognises it as UMTS 3G sim. Any suggestions? Thanks.

[K3 Note Q&A, Help & Troubleshooting] mickey78:
I've been reading here for some time never heard of it. Did you try disabling roaming completely in settings?

SETTINGS -> MOBILE NETWORKS -> ROAMING = OFF

Guys, in 1533 DEV, there is this additional line in updater-script, should we get rid of it as well? IT's the last line of the file below the part that we usually need to remove.

apply_sig(package_extract_file("sig/boot.sig"), "bootimg");
[K3 Note Q&A, Help & Troubleshooting] badbug:
No the problem is opposite. So the data only works if I keep the roaming on. If I turn it off the phone complains that "you have lost data connection as you have data roaming turned off" or something like that. Not a major issue as such but more annoying. I will also try to call my network. Could it be as the ROM is Indian?

Anyone successfully flashed TWRP or CWM on 1522 Stable? and how?

Or via fastboot?

And what custom recovery have you flashed?

I flashed official 1522 stable via sp flash tool,

but I can't flash twrp or cwm.

The flashing of the recovery went fine either with sp flash tool or fastboot I have No errors,

but when I reboot to recovery via adb or by pressing vol+ and vol- and power i'm stuck with the stock lenovo recovery.

I read in the post above mine that I need to remove the battery and hold power and vol+ and vol- and so on...

Hello,

I followed these steps to install the new ROM from VIBE UI but it's only in English and Chinese... I tried to install another one but it failed because my phone was no longer rooted. I tried to follow the same tuto to get it rooted but it failed saying "unauthorized" in step 1 of writing command lines.

Can you help me ? I can have access to the recovery but it's not allowing me to install anything, only update the ROM or wiping user data.

K3 Note Game Problem

I have some problems with games!specially HD games!

I installed many HD games but I could play just FIFA 14 and asphalt 8! these two games wasn't without problems too. asphalt 8 was laggy and FIFA 14 was slow.

I was played FIFA 14 in my LG L40 without any lag or low speed.

what's wrong with this phone?I updated my rom to Vibe UI 2.5_1523 and I didn't test any game on my previous rom.

what should I do?

Please Help
[K3 Note Q&A, Help & Troubleshooting] ErebosGR:
The MTK6752 in the K3 Note, while very fast on the CPU side, is coupled with a not-so-fast Mali T760 GPU.

The K3 Note also has a FullHD screen, meaning it has to draw a lot more pixels than your old LG.

That's why you get subpar framerates in very demanding AAA 3D games.

Bottom line, it's not an ideal gaming platform.

You should be able to pull the battery, put it back in and boot straight to recovery (hold power + volume up + volume down).

Though I I've stopped doing the fastboot flash method, I just flash this TWRP using SP Flash Tools instead (this is my personal Google drive folder, I downloaded that copy of TWRP from the 4pda.ru K3 note thread, but it's 404ing there now so I hosted my own copy). I prefer it to CWM personally.

Very slow charge... :(

Hi,

Have anybody experienced very slow battery charge ?

It happened to me with my brand new K3 Note (Rom VIBEUI_V2.5_V2_K50-T5_Gfan multilanguages from Needrom) during my second charge (the first one was before using the phone)

The problem occured this night when I put the device on charge using the original charger, when I woke up I was surprised the charge was not finished (it was only 25%)

When I checked the Battery widget app that shows battery charge graphics I could see a strange thing : the charge graphic curve is normal at the beginning and suddenly it became flat and the charge is very very slow as if the battery controler suddenly died.

I tried with another charger, the same thing it need at least 10 hours for charging !

I tried a factory reset but the problem is still here.

Thanks for your help.

Regards.

You cant update with custom recovery and with root. You need to unroot and then flash the lenovo stock recovery in the index thread. Guess you are on the ROW version.. Unroot your phone and flash stock recovery from fastboot then you can update via OTA. Everything is available on the index thread.

Good luck!

---------- Post added at 06:11 AM ---------- Previous post was at 06:05 AM ----------

Check the index thread.

---------- Post added at 06:16 AM ---------- Previous post was at 06:11 AM ----------

SO you're on a custom recovery i guess.. Try flashing any other ROM using TWRP/CWM recovery. Check the index thread. Everything is available. Or if you want the ROW ROM specifically you can flash it using SP flashtool. Next time if you want to root just flash the supersu.zip using custom recovery. No need to install through Kingroot or something.

[K3 Note Q&A, Help & Troubleshooting] shrihari123:
It is a little slow when it comes to charging. It doesn't have any quick charge. Its just the normal charge for a 2900 mAh battery so it will take time. But not like you said. It takes around 2 and half hours from empty to full. Its not detective. You just got the phone right so it must be charged fully till 100 and keep it charged for another 2 hours. It must get calibrated. After then use it normally and after it reaches to low, charge it again to 100%. It should solve the issue.
