FAQ - Frequently asked questions:

Q: What are the differences between EXUV and UV kernel versions?

A: The EXUV kernel versions have extremely undervolted settings for the cpu frequencies, they allows to have a very low battery drain, instead the UV kernel versions have undervolted settings a bit higher than EXUV versions, but always lower than stock kernel settings.

The EXUV kernel versions could give some problems (freezes, shutdowns, huge lags) on some devices because the cpu doesn't support too low voltage settings.

For a lower battery consumption, I suggest you to try EXUV versions first and to switch to UV versions only if you encounter one of the above mentioned problems.

Q: For v1.0 kernel builds, what are the differences between 396MB, 406MB and 416MB versions?

A: 396MB, 406MB and 416MB kernel versions have different free ram available for user space, with a higher free ram your device will work better with heavy apps, many concurrently used apps, heavy games, etc.

- 396MB versions are more stable, everything is fully working, but you could have some slowdowns with apps that require a high amount of free memory.

- 406MB versions have additional 10 MB of free ram, they are suitable for the users that use the device primarly for calls, messages, simple apps and simple games. The camera, video recording (both 480p and 720p modes) and video playback are fully working.

- 416MB versions have additional 20 MB of free ram, they are suitable for the users that use the device also with heavy apps, various concurrently used apps and games. The camera, video recording (both 480p and 720p modes) and video playback are fully working.

Q: How can I get the Performance and Developer Options entries inside Settings menu?

A: Go inside Settings -> About Phone -> Scroll down and tap 7 times on Build number (it's an Easter Egg).

Q: How can I get the log after an unexpected shutdown / reboot?

A: After an unexpected shutdown / reboot of the device, if the problem may be kernel related, you should have the /proc/last_kmsg, if so, send me that log and I'll check it to find the possible cause of the problem.

Q: How can I get the logs when I encounter strange system issues while it's running?

A: Check first if the problems could be related to an app you're using and if you changed something in the last days before facing those issues.

If the problem started after installing the kernel, then let me have you logcat and dmesg:

- Open Terminal Emulator and execute these commands:

su
dmesg > /sdcard/dmesg.txt
locat -v time -d > /sdcard/logcat.txt

- Open you preferred file manager and go inside the internal sd card partition /sdcard

- Send me the dmesg.txt and logcat.txt files, if you want zip them first

Q: How can I mount a shared Windows folder with CIFS module?

1) By using Terminal Emulator

mount -o unc=\\\\[COLOR="DarkGreen"][I]ip[/I][/COLOR]\\[COLOR="Blue"][I]share[/I][/COLOR],noserverino,username=[I][COLOR="DarkOrange"]user[/COLOR][/I],password=[I][COLOR="Lime"]password[/COLOR][/I] -t cifs //[COLOR="DarkGreen"]ip[/COLOR]/[COLOR="Blue"]share[/COLOR] [I][COLOR="DarkSlateGray"]/mnt/cifs[/COLOR][/I]

2) Downloading and using CifsManager and configuring the new share as follow:

- Share Path = ip/share

- Mount Point = /mnt/cifs/share

- Username = username

- Password = password

- Options = unc=\\\\ip\\share,noserverino

Where:

ip is the ip address of your pc where the folder is shared

share is the shared folder name

user is the user name that can access the shared folder

password is the user password

/mnt/cifs is the mount point (must be created if you'd like to use the command approach with Terminal Emulator)
