Thanks ems328i. It has worked. Now S is Off! I didnt have wifi ready at the time so couldnt install clock work mod recovery.
PS: Best way to flash newrom? All I want is hacking audio as it is low and inbuilt sip settings to accept 3G connections. Thanks again.
This version will also download and flash custom recovery if you want to, after getting S-OFF.
Note: the very first download missed some DLLs for the windows version, that should be included now.
Note2: There have been some reports (on dinc2) that the windows version might not always work like it should. Please report errors with that as descriptive as possible. The linux version should always work like it should.
Well basically these are the steps that worked for me:
1. Download the Android SDK from here: http://developer.android.com/sdk/index.html
2. Unzip and go into the folder you just downloaded
3. Run the 'android' application within the 'Tools' folder
4. Select 'Available Packages', and select 'Android SDK Platform-tools' and 'Android Compatibility package', and install these.
5. Make sure ADB can see your device by cd-ing into the SDK folder, and then the 'platform-tools' folder, and running './adb devices'. Your device should show up (mine had a string of question marks, but it should work as long as it is there)
6. Download AlphaRevX and get your beta key
7. Run AlphaRevX as root, and follow the instructions, and you should have S-OFF
These hboots are 'downgrade protected'. This is to ensure you don't accidently take an OTA or RUU, overwriting HBOOT, losing S-OFF (and might leave you in an unrootable state).
We will be releasing downgrader HBOOTs for several devices as soon as time permits.
You flash these first, then RUU, and go back to stock S-ON.
TBH: If you immediately want to revert to S-ON, why the hell are you flashing S-OFF in the first place? (except for warranty purposes - hw defects)
But I'm assuming that won't spontaneously happen 5 minutes after you S-OFF, right? So have some patience. It will be revertable.
