Samsung Galaxy S2

Whats the difference between downloading the miui rom from miui.com or miuiandroid.com?

Different versions. MIUI.com is the original, all others like GalnetMIUI and MIUIandroid work off that base.

I am quite a hectic user. Always have WiFi or 3G on. Whatsapp, odd call, SMS etc...
I used to get 2 to 3 days when I had my GS2.
You won't achieve decent time on a stock ROM though. Siyah kernel is the key.

Cool - so is it a huge effort to switch to Siyah kernel? Does that mean reboot and losing all my data?

You need root first, then can start flashing.
Search this thread for Siyah. When I still had my GS2 I posted how to root, flash, etc... It's somewhere in here

No, it's a simple enough process. But make sure you are on ICS first! If not- same process as below, just need a ROM to do it with.

• First ensure that you make a backup of your data. Call Log Backup & Restore, SMS Backup & Restore and App Backup & Restore are good apps to use to backup most of your stuff. Your photo's, videos etc can just be copied onto your PC.
• Install your USB drivers onto your PC. You might want to install Samsung Kies for this, then uninstall it but do not remove the drivers. But I think the phone installs it automatically when connected?
• Download Odin and the Siyah kernel. Make sure that you download the .TAR kernel file. Either way- make sure that Kies is not running when you perform the flashing.
• Open Odin. It should open fine if your drivers are installed. Make sure that your phone is not connected via USB at this point.
• Switch off your phone. Then reboot it into download mode by holding power + volume up + home. It should then ask you to press volume up (if I remember) to boot into download mode.
• Connect your USB cable to your phone. Odin should now say "Detected!" and a yellow strip will appear with a COM port on it.
• Select the PDA option on Odin, and search for the kernel you have downloaded.
• Click "Start" and wait while it flashes and reboots. Done! You should now see SuperUser in your list of applications. From there, download ExTweaks from the market to start customising your profile.

EDIT: Reboot is required, but you shouldn't lose any data. Never hurts to backup though

With Siyah's kernel I'm dual-booting "Resurrection Remix" and "CM9 nightly" fine but can one dual-boot Resurrection Remix and MIUI?

[OGroteKoning]

I installed MIUI to the secondary rom and for some reason it thinks that it should use my external sd card for its installation. I also noticed during flashing that MIUI installs its own kernel so I would suggest installing it as the primary rom, but before reboot, flash Siyah again to retain the kernel and dual boot. Make nandroid backups before flashing

Switch off your phone. Then reboot it into download mode by holding power + volume down + home. It should then ask you to press volume up (if I remember) to boot into download mode.

Fixed it for ya ...
I made this mistake before

Is anyone using MIUI Scotland 2.6.15?

But flashing the kernel onto the second ROM in CWM should fix this? However, I often flashed it as my secondary ROM without losing Siyah.

Also- the external SD card issue is an MIUI issue in general. Can be worked around with the Android gallery and a proper file explorer as opposed to the MIUI stuff.

Thanks! I couldn't remember and was a bit too lazy to reboot into download mode (used to my ROM doing it for me)

Still on the AdyScorpius version. But this one seems quite impressive, based on the changelog.

I'm running Gingerbread me thinks the one it came out with. Do I just proceed with your steps? I just need better battery life.

You must be on an ICS rom (stock Samsung or modified roms) to flash the ICS version of Siyah.

EDIT: You can start by flashing stock Samsung firmware from here

I don't know if this is strictly a Samsung Galaxy SII problem or just an Android problem, but I didn't want to start an unnecessary thread on it.

Since the ICS update my Facebook contacts in my phone book doesn't sync with my Whatsapp. I've tried countless re-installs, but to know avail. Anyone else have this problem? It's really annoying and I don't smaak to add hundreds of contacts manually to my Whatsapp. Someone help please!!

The problem is with the Facebook app. Rather sync your contacts to Google then upload to Whatsapp.
