[ROOT]Samsung Galaxy S2 Wimax-Japan

Kinda new at this but decided to give it a shot. There are many variants of the SG2 and recently in Japan, AU Kddi released a beast...

As reported by gsmarena.com-"The Galaxy S II ISW11SC has a 4.7-inch Super AMOLED HD display with a resolution of 1280 x 720 pixels, 1.4GHz dual-core Qualcomm QSC6085 processor, 8 megapixel rear camera with 1080p video recording, 2 megapixel front camera, 16GB internal memory, expandable memory, Wi-Fi 802.11a/b/g/n, Bluetooth 3.0 and NFC."

But being released in Japan there isn't much support for rooting on this phone. Part of the problem is most of its support and forums are in Japanese. After post a thread question, user tora201 showed me the light. He came across a japanese website with a super simple root for this phone. I decided to post it for all of us to use it with some simple instructions. Thanks tora201 for the help. None of this work is mine and all credit goes to the respective creators.

ROOT SCH-ISW11SC Samsung Galaxy S2 Wimax:

1.) Head over to this blog page, http://blog.livedoor.jp/kz_gin/archives/cat_136988.html, and download the two .zip files towards the bottom. They have the labels change_recovery_ISW11SC.zip, and root_ISW11SC.zip...or just use the attachments below...lol

2.) Copy the .zip files to a sd card. tora201 suggested using just an extra one you may have around. Place the sd card in your phone.

3.) With your phone powered off hold Volume Up, Home Button, and the Power Button at the same time until the phone boots into recovery mode.

4.) Using the Volume buttons and the Home Button as a select button, choose the change_recovery.zip from the sd card. (Y'all should know how to navigate these types of menus well, will help those that don't)

5.) Reboot the phone. Now power off the phone again and repeat step 3. Your phone should boot in to Clockworkmod Recovery. The Recovery is now navigated via the touch screen not the keys or buttons!!

6.) Like before go, select install .zip from sd....find your sd card and select root_.zip..then reboot....you should now notice Super User in your App Drawer!!!
Download Root Checker Basic to verify root access. Reinstall your primary sd card and your good to go!!

The only trouble I ran into was when installing the root.zip, it would not detect my external sd card. Repeatedly said "No Files Found". So I restarted the phone, went into the File Explorer, tracked down the root.zip on my external sd card, copied it to my internal sd card. Reboot into Clockworkmod Recovery, tracked down the root.zip through the same steps above expect in my internal sd card. Worked with no charm. Im not a programmer or anything like that, so if you guys have any questions I'll try to answer them the best I can. Thanks and good luck...As always not responsible for any damage to your phone..Come on though, this one is too easy to screw up...lol

Feel free to post some of your Quadrant Standard Scores...i got a high one unrooted...so just imagine what you root magic could do...

just be warned you will loose NFC and au Market access after rooting....the NFC is still there but the NFC.apk for this specific model is not there and it will not accept the NFC.apk thats floating around here...and I'm sure you weren't using au market to start with unless you read japanese fluently...lol

EDIT: let me know how the rooting went...i need to be sure my instructions are clear enough....and actually work

no other problems that I've ran into...my phone has been running just fine since early feb....just very slow support for it seeing as it being a Japanese phone...i know there is a lot of support but i don't read or speak japanese forums...im constantly trying to find and look up things though....feel free to through anything out there you find...

ok...imma give this a try..and let you know whats up....

Nope no go...here are the screen captures...any info on the nfc?

Sent from my ISW11SC using XDA

hmmm i didnt know there was a new version of the root....ill take a look at it....maybe its something to fixes the au Market and NFC faults....

well from what i get its a root method meant for LB# build before the update that you get from the network when you first turn it on. i emailed the guy to the best i could using Google Translate ( yeah i know) so hopefully he answers back. his instructions talk about using odin and what not. a little too much if you ask me...let me know if you install an ICS Rom...i been searching for answers on which ROM/baseband/kernel etc to use but to no luck..

well checked with the v2 root and all it is, is another way to root the device. i was told some people were having trouble with v2 so they came up with the one that is used in the guide...im seriously thinking of flashing a ROM from the Asian area built for the GS2 LTE...i dont want to lose signal and wimax function though...so i got to do more research..i think the SG2 LTE is the closest to our model

strange thing....theres an update today:for improved performance....40 mb ota but i cant install it..i guess because of the root....so im trying to find it manually and install using cwm...but cant locate it in the system...you guys come across it yet?

image didnt show up sooooo i have no idea what your working with...needs them specs
