LG isai LGL22 [Water-resistant and microSD slot available Japanese G2 variant]
General Q&A

Q. Is this a G2 variant though called isai?
A. Yes. Search LG OpenSource Code Distribution for "LGL22" and you can see it's classified as G2.

Q. What are the differences with original G2?
A. This device has a microSD card slot, a IR port, Osaifu-Keitai and TV. In addition, it's IPX5 / IPX7 water-resistant but water submersion can cause damage. The battery capacity is 2500mAh and it's reduced more than original G2's.

Q. Can I use this phone on GSM network?
A. Yes. A number of XDA members unlocked their phone and they are using in their countries. A unlock code for international LG G2 works on this phone.

Development Q&A

Q. Can I root by using IORoot?
A. No. IORoot exploit has been patched in all Japanese G2 variants. You need to use g2_support_tool in OP.

Q. Has Loki exploit been patched?
A. Loki is executable on JellyBean firmwares. On KitKat firmwares it has been patched, however, Bump! vulnerability hasn't been patched.

次にC:\ProgramData\LGMOBILEAXフォルダの中身をすべて削除し、ダウンロードした LGMOBILEAXフォルダの中身で置き換えます。
そうしたらLG_Mobile_offline_modeにあるScriptByMe.cmdを実行すると このような画面が表示されますので、以下のように選択して進めてください。

Thank you for your feedback.
It seems that the baseband is recognized but it can't recognize a SIM card yet due to a bug.
I heard about a sleep mode issue for the first time.

Issues is added in OP.
