Question [Q] How to Root Toshiba Regza IS04

I'm a complete noob and I've searched the forums and can't find an answer to my questions. (I'm sure there's some answer in Japanese on a Japanese forum somewhere, but my Japanese is not up to that level.)

I have a Toshiba Regza IS04 from AU (in Japan).
Running Android 2.2.2
Baseband Version 5014.1907.39
Kernel Version 2.6.32.9-rel ftml-android@ftml #1
Build Number FFK300

I have been researching rooting on and off for months since I first got the phone and have decided I would like to root it. My reasons for rooting:
1. I want to get rid of all the apps that were pre-installed that I don't use.
2. I would like to have the latest version of Android 4.0 Ice Cream Sandwich. (I doubt that another authorized upgrade from au is ever going to happen, since the 2.1 to 2.2 upgrade.)

It seems from reading forums that there are special builds of an OS depending on the phone?

My questions:
1. What is the best way to backup my phone before rooting?
2. What would be the best rooting method for my phone (SuperOneClick?)?
3. How can I (or even can I) upgrade my Android to 4.0?

Thanks for any help!!
Sam

To answer my own question, in case any one else wants to know:

Okay... it looks like I cannot post external links... until I post 8 times, which I don't really predict doing... so I'm going to try just removing the http at the beginning and see if it will go.


Superoneclick v2.2 does NOT work with this phone. It gets through "Rooting device... Step #7" but cannot remount.
Unrevoked does not work.
Z4root also does not work.

But I found a Japanese site with directions that did work! YES!!
hibari.2ch.net/test/read.cgi/smartphone/1320415141/

Somewhere in the page was the following information and link:
■auto_rootkit_is04_v0.5+suhax
hotfile.com/dl/134084004/f59084e/auto_rootkit_is04_v0.5suhax.zip.html

I downloaded the zip file and extracted it. I clicked on adb.exe first and then clicked on the auto_rootkit_is04 batch file. I just hit enter after each step. (It's in Japanese, but all it says is each step it is doing and then to hit any key.)

The first time I ran it, it did not work. The second time, I turned my phone off and on again before trying anything, and bingo: I had root!

Some of the Japanese threads were saying something about the problem with superoneclick was that the is04 took too long to mount and so there was an error. At least, I think that's what it said. My Japanese is okay, but not always good enough for this type of stuff.

I hope this can help someone else.

Thank you so much for this response!

I have the same phone, and I've been wanting to root it for a long time. There were so many pre-installed applications that are just hogging room, especially since I can't read Japanese well enough (yet).

I hope it works for you too!

I spent probably the equivalent of 2-3 days searching over the last few weeks, but couldn't find anything that I was comfortable with trying.

This morning, I finally got the nerve up to try superoneclick and was really disappointed when it wouldn't work. Then I started trying all kinds of methods, and about 8 hours later finally came across the method that worked!

It's probably the only thing frustrating sometimes about having a Japanese phone: lack of English support!

Now I'm just hoping I don't break it! I'm backing up all the apps with Titanium backup before I start deleting them one by one. I would hate to delete something that is crucial to the system and not be able to restore it. I'm also looking into other ways to backup the system.

One word of warning. Your au one market will not work unless you do one more step. It's mentioned in English in the readme file. I didn't bother because I never download from it anyway. (Although, I probably should just so I'll keep getting updates on some of the J apps that I do have.)

Default The File

I'm not sure if this is against the forum rules, but I have a copy of the zip file (well, a zipped up copy of the folder) from my computer. If you pm me, and I can send you it.
