I want to disable charging a battery while my phone is connected to my computer.
I found a solution and tried it but it didn't work at all.
1. Open any root file manager
2. Connect your mobile to the charger/USB
3. Open the following file: /sys/class/power_supply/battery/charging_enabled (It should be 1 by default)
4. Make it 0 while connected and save the file.
Does anyone know why it doesn't work?
And please let me know if you have a better idea.

This is very good for calibration battery in your new system
1. Turn on Wifi and connect on your network..
2. Turn on Bluetooth
3. Add Music widget on your desktop and play anything
4. Set volume on highest, and put it deep under feather bed because it will be very loud
5. Download any very very big file with Browser (e.g. files from Rapidshare or Megaupload)
6. Set Screen Timeout on "Never Timeout"
7. Set Max Brightness
8. If you can. Put Camera widget on your HomeScreen
9. Run Google maps and go anywhere in that
Optional (but very effective)
1a. install any FTP server (e.g. SwiFTP below FTPs)
Config it - OK - and hit Start
From your computer connect to your Phone with FTP client.
In your phone show iP on FTPs homescreen
And Download many files from your phone.. you can copy music to phone or to computer..
1b. you can download THIS tiwlan.ini (Its'nt my. So thanks to author)
Run Terminal and write this:
su
rwsystem
cp /"source"/tiwlan.ini /system/etc/wifi/tiwlan.ini
You need restart your wifi.. So Turn off Wifi and Turn on again.. This is for higher consumption.
If you have problem with anything, PM me and i can help you
If you know some more tweaks so write it..

Reserve for me
Hi there, I am using CM7 RC1v2 on my motorola defy. I am facing a problem which whenever i connect my phone to windows using phone portal the usb tether cnt be checked. But when i connect using "charge only" the things become available again but i still could not connect. Anybody face this problem and can help me to solve it? Thx very much!
Phone portal run on specific IP number and it uses different port and this explain why USB tether won't run.
I'm using it and here's my steps.
AFAIK, the pc required the USB tether driver for it to run properly. It should automatic install of the required driver. Once the driver is installed, you could perform a few steps here. I'm using Windows 7
1) Goto Control Panel - Network and Sharing Center - Change Adaptor settings.
2) Disable any active Local Area Connection if there are any of them running
3) Enable the one USB tether(it might already enabled by default but you could double check it).
4) It will auto verifying and connect once it done verified.
5) Start your internet browser and enjoy(you may need to do: Internet Option - Connections - Lan Settings - Unchecked proxy server .

I have tried following ur steps but it still can't work. My pc was able to install all the driver except that when installing MTP USB driver, it failed.
Hi,
Can some one help me in changing the Mac address.
Tried Busy box bit is not working...
I could get it working perfectly on my Note 2. I'm on the custom Eclipse V3 ROM.
Requirements : Root
0) Switch OFF WIFI
1) Use a file browser. Navigate to /efs/wifi/
2) Backup the file ".mac.info" (you need to enable "show hidden files" to be able to see this one)
3) Edit the file and put in the MAC address you want.
4) Save the file to the same location
5) Switch on wifi (reboot not required)
I enabled FS access, per instructions here: http://forum.xda-developers.com/win...e/tutorial-how-to-change-icons-quick-t3256590 and upon reboot of the phone, connecting the phone via USB no longer works (I can't access anything through file explorer)
I'm attaching a screenshot of how it shows up in device manager.
I have already made this change to the phone's registry:
HKLM/software/microsoft/mtp/datastore changed back to C:\Data\Users\PUBLIC - still no luck.
Is there another registry key that needs to be modified? Other USBs and devices work on the computer, so its not an issue with the computer.
EDIT:
This solution is fixed, although I don't know what caused it.
I installed the WPTweaker app: http://forum.xda-developers.com/win...ptweakers-2015-08-17-added-5th-quick-t3180474
Toggled the "FS Access" setting; reboot the phone (left USB plugged into PC).
Upon restart, toggled again, restart (left USB plugged into PC).
On the 2nd restart, Windows Explorer just loaded my phone, with full FS Access.
The settings (and FS access) survived a third reboot and I still have USB access!
If anyone knows WHY the USB access was originally lost in the first place, I'd love to hear any suggestions. It's great it's "fixed," but knowing why would be awesome. I am wondering if CustomPFD's FS Access settings/registry save to the Data key is somehow imperfect and either saves corrupt or doesn't save. CustomPFD writes other keys successfully and changes are saved upon subsequent reboots, but for some reason, FS Access just would not play nice.
(For reference, my phone is Lumia 830 RM-985 with Windows 10 Insider, Slow ring build)
I have fixed mine.
There was no MAC address programmed to the device at factory. That's an omission. So the WIFI driver when activated after restart or by turning wifi off/on notices that and gives a temporary MAC address.
That address changes in the last bytes.
The solution is to write a WIFI MAC address with an appropriate tool. I did use SN_Writer just be careful to leave the other data alone.
I guess the same happens with the Bluetooth address but did not check that out yet.
0) Choose a valid MAC just look under settings the temporary one that your phone uses that's ok
1) Install VCOM Driver if you don't have it yet
If you use Windows 10 then you have to temporarily disable Driver Signature check since those drivers are not signed
Instructions and download here
http://forum.xda-developers.com/elephone-m2/help/windows-10-mtk-vcom-usb-drivers-32-64-t3267033
2) Download the SN_Writer I did use that one, password is mtk2000
http://mtk2000.ucoz.ru/down18/SN_Writer_Tool_v1.1648.rar
3) Download the right stock rom for your device you need the file which is named like the one I did use
APDB_MT6797_S01_alps-mp-m0.mp9_W16.48
4) Power off phone
5) In SN_Writer hit System Config uncheck everything and check Wifi Adress on the left side
In database file AP_DB use the file from 3)
That should do it.
Hit Start and entry the MAC just the digits no dashes etc.
Connect the phone while holding Volume Down.
That should do it.
Thanks for the write up, I got my S7 WiFi MAC address fixed now too, with your steps !!
Bluetooth appears already fixed/correct. (Also I haven't noticed my paired bluetooth devices loosing pairing..)

Great! Also good that Bluetooth is correct. Did not pair anything yet but good to know there won't be similar problems.

Sorry for my late answer.
Double check step 3) you need the correct file from the correct stock rom for your device.
If that still doesn't work I would try reflashing the bootloader preloader (only) from stock ROM and try again.
It should work.
I'm not having any luck with my device on windows 10.
Whenever I try to connect my device to windows via usb, a pop appears - (USB device not recognized-the last USB device you connected to this computer malfunctioned ,and Windows does not recognize it) .
I've also tried to clean up my usb drivers and re-install MTK preloader.
Any advice how I might fix this?
File APDB_MT6797_S01_alps-mp-m0.mp9_W16.48?
