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.

KDZ flash instruction by @hoangthuong266
If you have rooted or installed a ROM or a recovery, flash 10b tot before flashing 20b kdz so as to restore the firmware to factory condition.

First, install B2Cappsetup.exe.
Second, delete C:\ProgramData\LGMOBILEAX folder and replace by LGMOBILEAX folder.
Third, run ScriptByMe.cmd in LG_Mobile_offline_mode folder, after that we enter to show this and select each dialog as below.

まずB2Cappsetup.exeをインストールします。
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.

    Followed your instructions and i've have my isai 20b rooted. Thank you.
    But no custom recovery, right?

    yes , you are right.
    It needs new loki method or other.



    Sent from my L-01F using XDA Premium 4 mobile app
    4
    I found following notes from other site:

    The 4.4 root is still not a full root.
    Current Limitations:
    1) it can't mount read/write full access to /system.
    2) no custom recovery
    3) stock recovery becomes black screen

    1) it can't mount read/write full access to /system.
    -> known issue, I improved it a little, but some apk such as using internal busybox can not yet.

    2) no custom recovery
    -> this is not limitation of rooting.

    3) stock recovery becomes black screen
    -> this is normal at LGL22 stock recovery.
    if use recovery mode , you shuld run "adb reboot recovery" by PC.

    Thank you.
