Hello,
I'm the administrator 's GadgeTwo !ヽ(´ー｀)ノ

This time I got a question from a foreign country.
So I will explain the method of SIM Unlock and DoCoMoization in English.

We will show you how to SIM Unlock and DoCoMoization at SCV33 / SCV35 / SCV36 / SCV37.
※Because the page has become plural, I integrated page.

・Corresponding terminal.
Galaxy S7 Edge SCV33 -> SC-02H
Galaxy S8 SCV35 -> SC-03J
Galaxy S8+ SCV36 -> SC-02J
Galaxy Note8 SCV37 -> SC-01K





Let's explain how to the SIM Unlock and DoCoMoization of the SCV3x.
Originally au does not accept SIM unlock unless it is 101 days after purchase date.
However, by doing this method, you can immediately release SIM lock.
In addition, Docomo's FOMA Plus Area (B6) and LTE Band (B19) will be available.
It is the best choice to use with MVNO carrier of Japanese career.
This can also be used outside of Japan !(*´∀｀*)b"

★Notes:
This work is an act of losing guarantee of career.
It is a complete self-responsibility work.
However, terminal remodeling judgment is not displayed in this work.
That is, the Knox counter does not go up.
Therefore, By returning to au Genuine ROM, repair can be accepted at au shop in Japan.
All data will be deleted. Please back up the data before work.

If you do not need Samsung application please unzip and install Samsung Android USB Driver (USB_Drivers_1.5.27.0.rar).
※Installing the driver takes some time.

By the way, with Smart Switch PC,
It is integrated software for Galaxy, it is software which can perform data backup, recovery, update, migration from other models and so on.
This includes the latest drivers for Galaxy.
In other words it is iTune of Galaxy version.

Prepare ROM burning with Odin3

Next, burn the docomo ROM on the terminal, then SIM Unlock and DoCoMoization.
If you do not make a mistake in the procedure, please do not worry because it will not break.
※Let's charge the phone before ROM burning.
After starting Odin 3, specify ROM to be burned.
Before specifying the ROM, connect the PC and the Phone and check if the Samsung driver is correctly installed.
When the terminal is connected to the personal computer with the power on, the connection status is OK if a light blue COM number is displayed at "ID: COM" on the upper left of Odin3.
The specification method of ROM is as follows.(Not press Start)。
BL Button → Those whose file name starts with "BL_xxx"
AP Button → Those whose file name starts with "AP_xxx"
CP Button → Those whose file name starts with "CP_xxx"
CSC Button → Those whose file name starts with "CSC_xxx"
※Attention!：Options and Pit items are for people who understand the contents.
Please do not touch Options and pit if you do not understand the meaning of the setting item.

Operate the terminal

Enter Download Mode to write the ROM to the terminal.

Turn off the terminal and press and hold down the [Power] button on the right while holding down the [Volume Down] + [Home] button.

・Galaxy S8/S8+/Note8
Turn off the terminal and press and hold down the [Power] button on the right while holding down the [Volume Down] + [Bixby] button on the left side.

Since the selection screen of DawnloadMode is displayed, press the [Volume Up button].
To stop ROM burning, press the [Volume Down] button to reboot.
※I did not take pictures of this part. Will use the photo of SC-02H instead.
　　　　

Burn DoCoMo ROM

When [Downloading ...] is displayed on the phone screen, connect the PC and the terminal with USB.
If you press the [Start] button of Odin3 prepared in 「3. Odin 3 ROM burn preparation」 in the previous section, ROM burning start.
Wait a few minutes as the progress bar appears on Odin3 screen.

How to start Recovery Mode

When the ROM burning is completed it will be restarted and "system update" will be displayed,
When the display disappears, enter RecoveryMode by pressing and holding the volume [UP] + [Bixby] + [Power] button on the main unit at the moment of disappearance.
If you miss the timing, you can press the [Volume Down] + [Power] button for a long time to force reset.
Press and hold [Volume UP] + [Bixby] + [Power] button at the moment of resetting and put it into RecoveryMode.

If you do not enter RecoveryMode and start up the system as it is,
A warning is issued due to ownership or signature of data and it can not be started.
I think I was urged to initialize.

Initialize terminal from Recovery Mode

After entering RecoveryMode, select "Wipe Date" and initialize the terminal.
After initialization is completed, if you perform Reboot, SIM Unlock and DoCoMoization are completed.
※Wipe Data/factory reset → Yes → Reboot system now

Return to the 3. Prepare ROM burning with Odin3 in the previous section.
By specifying the downloaded au genuine ROM in the same way and burning the ROM, you can return to the au genuine state.

◆Attention point of NFC/Felica.
If NFC/Felica is used with au genuine ROM, it will not be usable in a docomo state.
In that case you can use NFC/Felica if you return to au genuine ROM.
This is presumed to be because carrier information etc. are written in NFC/Felica chip when NFC/Felica is first initialized.
This is the end of work♪
If you can check the operation, I'm happy if you can post comments on this blog.(*´ω｀*)
