I ported cm 12.1 for my device on 3.4.67 kernel on mt6582 chipset..
ReplyDeleteNow when I open any music app and play songs... They just keep on going to next song and doesn't actually play...
It looks like a memory issue. media player is not able to access your songs that's why it is jumping to next song. If you are using xinternalsd. go in option and disable music player and media storage in it.

ReplyDeleteYou did not mention on which rom you are facing this problem. Base chipset etc.?
DeleteThere could be two conditions hear one is that rom is not ported correctly. re-port the rom. make sure your mount points are correct in updater script.

To fix the signal (RIL) I need to copy the whole system/etc/permissions folder from stock to port?
ReplyDeleteTo fix the signal (RIL) I need to copy the whole system/etc/permissions folder from stock to port?
ReplyDeleteIn kitkat based roms you have to use permission files from port rom.
DeleteOnly use below files from stock.
1. features.xml
2. handheld_core_hardware.xml
3. media_codecs.xml
4. platform.xml
If your port rom have signal issue then your ported rom will also face signal issue.
It is rare to face signal issues or unstable signal.
Normally in kitkat roms this issue occurs because of Invalid IMEI/Baseband.
Check imei with *#06# if it says unknown
view this guide to fix it

DeleteSir I try to port:
ReplyDeleteMt6582 to Mt6582
Kitkat to Kitkat
3.4.67 to 3.4.67
I used many guide. But after flash it stuck and reboot,like many reboot later it booted,but after boot it again started to reboot
Is there anyway to fix ?
(I'm getting same problem on color is ROM on mt6572 kk)
Have you tried the guides from this blog.
DeleteI recommend to port lollipop because it is lot easier then porting kitkat. when you get master in lollipop after that you can try kitkat.
Still if you want kitkat. make sure your partitions are correct. Open vold and storage.xml and see if the storage paths are correct.
And if its stuck on bootanimation. DO this
Do a full wipe before flashing rom then
1. flash rom > boot > if stuck > boot into recovery > factory reset > reboot.
2. flash rom > boot > if stuck > boot into recovery > flash rom again > reboot.
Sir the rom booted
ReplyDeleteBut the main problem is :the rom is auto rebooting(mt6582)
I tried to Port lollipop, there is no problem(mt6572)
On all roms? If its happening only on color os. please take a logcat so i can find what the actual problem is.
DeleteAnd this same problem on my mt6572 kk on color os rom

ReplyDeletei upguard iris x5(mtk6582) kitkat to lollipop i have 1 & 2. sim2 is working correctly but problem in sim1 when i call from sim 1 it say no cellular network abvailable.
ReplyDeleteMethod – 1
DeleteThis method is used to select network operator manually.
Go to Menu-> Setting
Find and Click on Wireless and Networks
Tap on Mobile Networks
There will be option to choose Mobile Operator
Tap on Manual and find your operator
After choosing operator Restart your mobile
Yea, you did it!
Method – 2
Due to improper broadcasting of radio signals from your device may get this error. Here is a solution that will overcome mobile network not available problem.
Open dialer and dial *#*#4636#*#*
Testing Menu will be prompt
Now tap on Phone/Device Information
Then you’ll find ‘Run Ping Test’ button, click on that
One drop-down menu will appear, click on that and select GSM Auto (PRL)
Now click on Turn Radio Off button
Restart your device, done!
Method – 3
If none of above method works then this is the last option you have to do.
Reflash the whole firmware if the SP tool flashable files are available then flash that. search this blog for the method.
