ROM for Kingzone N3

[Athos]

okay, that sounds about right. If you have a lower class SD card lying around, maybe you can try popping that in.
Have you tried unmounting and re-mounting the SD card?
Also, try and see if maybe the ROM has the two mixed up. Set the default write disk to internal storage, and see if app data goes to SD card.
I haven't encountered this issue, but these are some things I'd try.

About the camera problem, I just saw your other thread. I would have to agree with Sniper47, that could be a hardware issue. If there are any ROM updates for your phone, it's worth a shot to try as well.
I saw this [Only registered and activated users can see links Click here to register] but i would recommend contacting the uploader to find out if this is a compatible ROM for your phone. Please be cautious, and have a backup ready.

So I managed to install the update N3 rom, all the issues are magically solved ; the spot is gone and when I'm using the camera the folder DCIM is now on the sdcard. Except the force closed smallwindow in google play music (post #3) it still persists. Otherwise I lost root on it ; can you tell me another method how I should recover it please. Thanks again

How did you root your phone before?
You can try the auto root tools here http://www.chinaphonearena.com/forum/Forum-Rooting-Tools
Is the update KitKat? Try iroot first (PC version), if it doesn't work, move along and try the others.

A last resort would be creating and installing CWM then pushing SuperSU through CWM.
After that, you boot and update binaries in the SuperSU app.
Tutorial to creating CWM while unrooted: http://www.chinaphonearena.com/forum/Thread-Tutorial-Ultimate-no-root-backup-CWM-MT6582-MT6592-MT6589-MT6589T-MT6577-MT6595
Link to SuperSU download: http://www.chinaphonearena.com/forum/Thread-Tool-SuperSU-for-rooting-from-recovery
Download and unrar the file, place the zip file (not rar) in the root of your SD card.
Install it through CWM.

For the Google play problem, make sure your gapps are updated. try clearing the cache for the suspicious app from Settings > Apps > All. If that doesn't work, you can try clearing the cache through recovery.

Hello there,
I'm sorry to bugging you again, there were another bug found with my kingzone phone ; it seems that the imei number is not listed in the database of our service provider ; so the 4G network is locked because in their database the phone may be listed as a 3G device ; you can check that here [Only registered and activated users can see links Click here to register] . Most of 4G smartphones imported from China have the same issue, we have a lot of complaints. I think it can be solved by replacing the imei number or contact directly the manufacturer to update the database. What would you think ?

I guess you can try changing your IMEI to one that will get you 4G service. See this tutorial [Only registered and activated users can see links Click here to register]

But before you do, make a backup of your existing IMEI, just in case changing it makes things worse. Take a look at this one [Only registered and activated users can see links Click here to register] To make a backup, just follow the second part of the guide (done on your phone), and at the end, choose Backup IMEI to SDCARD (MTK).
If you will need to restore your original IMEIs later, just use the backup.

That's nice to hear from you Athos ; but now I must find the right imei which is known by our provider. On the other hand, I've heard that a lollipop rom is out for this phone, do you have some news about ?
