DoCoMo SC-03E Samsung Galaxy S III alpha
How to change/modify Tethering DoCoMo preset APN[/size]​
This work has been edited collecting many info taken from many guides on-line… and tested by me.
A well known issue after SIM-Unlocking the SC-03E, is that you can’t change the APN on your own provider’s APN when you want use the Tethering.
Even if you set your provider’s APN in the APNs settings, when you switch on the Wi-Fi Tethering the APN automatically sets itself on a specified DoCoMo APN (dcmtrg.ne.jp) to check your data traffic by your PC.
So, if you decide to use a no-DoCoMo SIM Card, you can’t use your smartphone as modem for your PC.
There are 3 ways to get over this problem, but in all of them you need a rooted ROM (so, be careful at what you are doing).
If you need to keep a DoCoMo ROM, at present the only Rooted “DoCoMo” ROMs working for this job are the ROMs from aki0306.
You can find them here.
If you don’t need a DoCoMo, you can choose a Custom ROM as the CyanogenMod10.1 JP Remix for SC-03E.
Thaks to kizuki.buy and theDroidfanatic for some tips.
[size=+2]Read below for the 3 methods[/size]​

Method n. 1
[size=+1]Method n. 1 : Editing the "framework-res.apk" from DoCoMo SC-03E ROM.[/size]​
1. Flashing
Flash the aki0306 Rooted Stock ROM on your phone by the ODIN tool (there are thousands of guides about how to use it).
[N. B. after flashing this ROM, the “Download Mode” will display: that your phone has a “CUSTOM” ROM on board
Custom binary Download: No
Current binary: Samsung Official
System Status: Custom
(look here)]
2. On your Phone.
Go in Settings-Developers Options... Enable.
Enable USB debugging.
Then on Settings-Security, enable “Unknown sources” to let unsigned apps.
At this point, from Google Play, install on your phone the free apps:
SuperSU,
Root Browser Lite
ServiceMode Shortcut.
Install SuperSU, Open, Continue, Normal (to and let it install the SU binary).
Install Root Browser Lite.
By "Root Browser Lite" navigate to “\system\framework” and copy the system file “framework-res.apk” from there to your SD Card.
When the pop-up comes, grant to Root Browser Lite the permissions by SuperSU.
Then Cut and Paste “framework-res.apk” from the SD Card to your PC.
3. On your PC, download and install.
Download and install with default settings Java Development Kit (JDK).
Then, set the Environment Variables Paths [Go to Start, search for “Environment”, choose “Edit Environment Variables for your Account”.
Edit 'PATH,' and 'CLASSPATH.' (If you don't have them, just add them, and name them PATH and CLASSPATH)
For PATH, give as the Variable Value: C:\Program Files\Java\jdkXXX\bin; where XXX is the JDK version.
For CLASSPATH, give as the Variable Value: "C:\Program Files\Java\jdkXXX\jre\lib; where XXX is the JDK version)].
Download and install Notepad++.
Download and unzip somewhere APK Manager / APK Multi-Tool.
4. Edit “framework-res.apk” with APK Manager.
Go where you unzipped APK Manager and set the folders for working (\APK-Multi-Tool\Setup.bat, 3, Enter).
Then copy “framework-res.apk” from the place you saved it to the place-here-for-modding folder.
Then...
Script.bat, Enter, 24 (set current project), Enter, 1 (framework-res.apk), Enter, 9 (Decompile apk), Enter.
Wait for it complete.
Then go to
\APK-Multi-Toolv1.0.11\APK-Multi-Tool\projects\framework-res.apk\res\values
searching for the file strings.xml.
Open “strings.xml” with Notepad++ and edit the line number 57.
Changing the a part of the code from
docomo_hotspot,dcmtrg.ne.jp,,,,,,,,,440,10,,default,supl
to
docomo_hotspot,YOUR_APN,,,,,,,,,YOUR_MCC,YOUR_MNC,,YOUR_APN_TYPE
following the rule
NAME,APN,PROXY,PORT,USER_NAME,PASSWORD,SERVER,MMSC ,MMSPROXY,MMS_PORT,MCC,MNC,AUTHENTICATION_TYPE,APN _Type
Using the APN settings from your provider, but KEEPING docomo_hotspot at the first place (!).
Then, save.
Then, go back to Script.bat.
Select 11 (Compile System APK Files).
Enter.
Select “y”.
Then wait and DON’T PRESS Enter.
Then go in \APK-Multi-Tool\keep
There delete the file “resources.arsc”.
Then, go back to Script.bat window and I press “Enter”.
At the end of the process, go to
\APK-Multi-Toolv1.0.11\APK-Multi-Tool\place-apk-here-for-modding
You will find the file “unsignedframework-res.apk”.
Move the file “unsignedframework-res.apk” somewhere and rename it in “framework-res.apk”, then copy it into the Phone’s SD Card.
5. Overwrite the original “framework-res.apk”.
On the phone, using Root Browser Lite Copy and Paste that modified “framework-res.apk” from the SD Card to “\system\framework” folder and overwrite the original one.
It will need some time, in the meanwhile you will see some error messages.
Don’t worry and wait for the message about the complete overwriting.
Then restart the Phone.
If everything is gone in the right way, the Phone will reboot normally.
(In any case, if the phone goes in boot-loop, start the phone in “recovery mode” and perform a factory reset).
6. Checking the APN on Tethering.
Switch on the Wi-Fi Tethering then launch “ServiceMode Shortcut”.
Select ServiceMode->Docomo Debug Screen->PND information.
You should see the APN you did set in the XML file before.

Method n. 2
[size=+1]Method n. 2 : Xposed Installer ROM modding + “matsumod.apk” Module.[/size]​
1. Flash the aki0306 Rooted Stock ROM on your phone by the ODIN tool (there are thousands of guides about how to use it).
N. B. after flashing this ROM, the “Download Mode” will display: that your phone has a “CUSTOM” ROM on board
Custom binary Download: No
Current binary: Samsung Official
System Status: Custom
(look here)]
2. On your Phone
Go in Settings->Developers Options... Enable.
Enable USB debugging.
Then on Settings->Security, enable “Unknown sources” to let unsigned apps.
Download and install ServiceMode Shortcut.
Download and install SuperSU.
Install SuperSU, Open, Continue, Normal (to and let it install the SU binary).
Download XposedInstaller_X.X.X.apk and install it on your phone.
Open, then press Install/Update.
When the pop-up comes, grant to Root Browser Lite the permissions by SuperSU.
Wait, then press Reboot.
Download the Xposed Module “matsumod.apk" and install it on your phone.
Open then check “enable Tethering when use MVNO sim”.
3. Open again Xposed Installer and select the Modules tab and check (enable) Matsumod.
4. Set/edit the APN from your provider into
Settings->More Settings->Mobile networks->Access Point Names
and select it.
5. RESTART the Phone.
6. Switch on the Wi-Fi Tethering, then launch “ServiceMode Shortcut”.
Select, ServiceMode->Docomo Debug Screen->PND information.
You should see the APN you did set in APN settings before.
Note:
If you are using a DoCoMo SIM Card and you don’t wish DoCoMo to know if you are using the phone as modem for PC or just as smartphone for browsing, select SP Mode APN and enable Matsumod.
The Tethering will keep on SP Mode APN.

Method n. 3
[SIZE=+1]Method n. 3 : Custom recovery “CWM ClockworkMod” + Custom ROM “CyanogenMod10.1 JP Remix for SC-03E” [/SIZE]​
If you don’t need the DoCoMo ROM, you can use a custom ROM to have full control on your APNs even for Tethering.
[N. B. after flashing CWM and CyanogenMod10.1, the “Download Mode” will display: that your phone has “Custom” Binary and a “CUSTOM” ROM on board, so the counter will increase.
Custom binary Download: YES (1 counts)
Current binary: Samsung Official
System Status: Custom
(check here to reset)]
1. Download CyanogenMod10.1 JP Remix for SC-03E (cm-10.1-20130513-KBC-sc03e-signed.zip pw: 1234) and copy the ZIP file on your SD Card.
2. Download CWM ClockworkMod and flash it on your phone by the ODIN tool (there are thousands of guides about how to use it).
3. Restart your phone in Recovery Mode (Power+VolumeUP+Home).
Wipe cache partition, data/factory reset,
then "mounts and storage", "Mount /external_sd", "Go Back",
"install zip from sd card", "choose zip from external sdcard", select CyanogenMod10.1 JP Remix for SC-03E zip file, then install.
4. Enjoy your new ROM.

How to dual boot: ONLY FOR GALAXY S2
Warning: This procedure doesn't really work anymore. It only works with Android 4 (Ice Cream Sandwich) and Siyah Kernel v 5.0.1. Later versions of either won't work. Consider this guide archived, and use it at your own risk.
If you want to test B2G from time to time but continue using Android as your main OS and you have a Samsung Galaxy S2, you can choose to install B2G in a separate partition (which is already present on the phone) and choose where to boot into when your device starts.
Prerequisites
In order to dual boot Android and B2G, you have to meet these prerequisites:
You have to have built B2G for the Galaxy S2
You have to download the Siyah kernel v. 5.0.1 for the Galaxy S2
You need the tool simg2img, that you get automatically if you build B2G following the guide on MDN
You need the heimdall tool, best if version 1.3.1 as you may encounter problems with version 1.3.2
One-time operations
There are several operations to do in order to get a working dual boot. The following ones need to be done the first time only.
In order to use heimdall without requiring root access, you should create a file called android.rules (the portion of the name before the .rules extension is arbitrary) and place it in /etc/udev/rules.d. The file should contain a line line the following:
Code:
SUBSYSTEM=="usb", ATTRS{idVendor}=="04e8", MODE="0666"
In order to activate this rule, you should restart udev:
Code:
sudo service udev restart
and then unplug and replug in the phone. The above rule will also allow adb to access the SGS2 without requiring root privlidges.
Flashing the Siyah kernel
The Siyah kernel is mandatory for the dual boot, because it is this kernel that manages it. Once you have downloaded and decompressed the tar file, you'll be left with a file named zImage. In order to flash it on your phone you have to follow these steps:
Switch off your phone
Reboot in download mode (press together volume down + home + power buttons and then, when asked, volume up button)
Use heimdall to flash the kernel with the following command (your phone needs to be connected to your PC):
heimdall flash --kernel /path/to/zImage
Once the kernel is flashed the phone will reboot.
Preparing the B2G rom environment
Once you've installed the Siyah kernel, it's time to use its functions to prepare the environment to install your B2G image in the secondary partition. Follow these steps:
Switch off your phone
Reboot in recovery mode (press together volume up + home + power buttons)
In the CWMR Touch interface, go to dual-boot options -> Wipe 2ndROM data/cache -> Yes - Wipe. This operation will take some time
Once the operation is finished, select Go Back and then reboot system now to reboot your phone. If you check, inside the internal SD card of your phone you'll now have a .secondrom directory with inside two files named cache.img and data.img.
B2G update operations
The following operations need to be done every time you build a new version of B2G.
In order to simplify command line instructions, it's advised to copy all needed files in a same folder of your choice. These are the files that need to be copied inside the folder:
Code:
simg2img, found in B2G/out/target/product/galaxys2/system/bin/
system.img, found in B2G/out/target/product/galaxys2/
userdata.img, found in B2G/out/target/product/galaxys2/
Once you have all the files in one place, do the following:
Create a data.img file out of the sparse file userdata.img. You can do it with the following command:
Code:
simg2img userdata.img data.img
Put the data.img file on your phone's .secondrom folder. You can do this either by enabling file storage mode on your phone and connecting it to your PC or, if you have USB Debug active, you can use adb:
adb push /path/to/data.img /sdcard/.secondrom/data.img
Switch off your phone
Reboot in download mode (press together volume down + home + power buttons and then, when asked, volume up button)
Use heimdall to flash B2G firmware inside the second partition:
heimdall flash --hidden system.img
Once the flash is finished, your phone will reboot and at boot time you can boot into your second rom (the B2G one) by pressing the home button during the bootloader countdown. If everything has gone right, once you've finished booting B2G you'll have a black screen on your phone. You now have to install Gaia.
Note: Depending on how you want to test B2G, you may not want to put a new data.img file on the phone every time you update B2G, as it will wipe all of your preferences, installed applications and in general pretty much everything you've done while using B2G.
Boot operations
The following operations need to be done every time you boot inside B2G.
Unfortunately, there's no simple way to put Gaia inside the system.img B2G image, and it get lost when you switch off your phone, so you'll need to install Gaia again every time you boot inside B2G. To install Gaia, type the following on a console after you've booted your phone inside B2G (so you have a black screen) and have connected your phone to your PC:
cd B2G/gaia
GAIA_DOMAIN=foo.org make install-gaia
After the upload of Gaia is completed, on your phone's screen the B2G interface will appear.

Dual Boot for Galaxy S5 SM-G901F

Dual Boot your Galaxy S5 G901F
First i'm not a programmer, I am an enthusiast user who likes to use the full potential of his phone
I found a way to dual boot the G901F though there is little development support for it
(too bad despite the potential of this device)
I like to thanks @chenxiaolong for his dual boot app for the Galaxy S4 witch i used for this to happen
I also like to thanks @aukhan for his post on how to dual boot the Note4 from where i got the link for "swap roms.apk"
Now lets beggin
0. you should have a backup of your primary rom.zip and your actual kernel.zip
and of corce your device rooted
1. download and install DualBootPatcher for win 32 and android from @chenxiaolong post
http://forum.xda-developers.com/showthread.php?t=2447534
I installed DualBootPatcher.apk on the phone and for pathing i used DualBootPatcher for win32 on my pc
2. open DualBootPatcher for win32
3. on the new window hit the "chose file" tab
4. select your secondary rom.zip (eg.cm12.1 or cm13)
5. on "device" section select "trlte - SamsungGalaxyNote4(Snapdragon)"
i chose this thinking that Note4 Snapdragon has the same hardware as G901F and it could influence the instalation
6. on "install to" section select secondary
now hit the "start patching" tab and wait for the rom to be patched
7. inside the new rom_patched.zip in the "multiboot" folder you will find a file named "info.prop"
8. open it with a text editor and at the bottom you will find the line:
"mbtool.installer.ignore-codename=false"
9. change "false" to "true"
10. repeat steps 2-9 for your downloader version of gapps
11. install "swap roms.apk" from this link
https://www.dropbox.com/s/97st26iuk0jc9vc/Swap_Roms.3.apk?dl=0
but dont open it yet
12. with a file explorer on your phone go to sdcard/MultiBoot folder
13. there should be two folders "dual" and "primary"
14. if not, create them
asuming that you have both of your primary(actually installed) and secondary rom images (.zip files)
follow the next steps
15. copy boot.img from secondary patched rom to dual folder (sdcard/MultiBoot/dual)
16. copy boot.img from primary rom to primary folder (sdcard/MultiBoot/primary)
now copy rom_patched.zip and gapps_pathed.zip to your device
remember and don't forghet to edit "info.prop" from step 7 or the installation won't work
17. open DualBootPatcher installed on your device
18. hit the 3 lines menu from the top-left corner and select "roms"
19. hit the red icon on the bottom right corner, then the "+" one and install your secondary rom
after the istallation finishes install the gapps
20. after the install, exit the app
21. open "swap roms" witch you installed in step 11 and select dual
you should see a message telling that the kernel has been flashed
after it is done, click reboot
22. the device should boot to secondary rom
23. after configuring your new rom, repeat step 11 (install "swap roms.apk")
25. now to switch between roms use "swap roms" (select primary or dual depending on witch rom you are)
26. if anithing goes wrong go to recovery and flash your primary_kernel.zip
it should boot to primary rom
27. you can delete the secondary rom via DualBootPatcher->roms
For each .zip file you want to flash to your secondary rom repeat steps 2-9
I hope that you found this usefull and don't forget to press "thaks"​

Thx

@chenxiaolong at my request added full support to dual boot the G901F so use his app from this thread : http://forum.xda-developers.com/showthread.php?t=2447534

this being said it's time to close this thread

I have it working .
One thing ..
When you switch ROM .
Don't do it directly .
First update the ramdisk of that ROM on which you wanna switch .
Otherwise it doesn't boot
