just a question - i did a CWM backup. is it a complete 100% image that fully restores everything back to that point (like windows 7 PC backup) with one click?

Yep. Very handy to have when flashing. :)

I use it every time I flash roms and themes, and occasionally transfer a copy to my pc (just in case...)

Do make a back-up of your EFS though. There's a simple tool here for that. The companion tool will back up and restore the efs and help remove the warning triangle.

I didn't back-up mine for ages, now I've got a copy on the pc. ;)

The triangle isn't a problem, have a go at using the companion tool I linked before. There's a procedure listed with the tool. It only shows that you've flashed a non stock kernel, not really a problem unless you have to send your phone back. It affects nothing.

Cheers for that K1000716! Procedure looks easy. As you said, not a major unless I was sending the phone back.

fergis: So many guides about updating to 2.3.4 say "Install Supercore using ODIN" but I have been unable to find any detailed instructions of how to do this. Any ideas?

I have looked through Brendan's guide and canot see anything relevant...

Make sure your phone is rooted (as per the faq), and install the rom of your choice. They are all 2.3.4.

Damager: Okay

Telecom Galaxy S II users, which custom roms have you got running?

Lite'ning Rom v6.1 with SpeedMod K1-T39 kernel

Cheers K1000716!

Any particular reason over other ROMS? Just wondering which one to flash as my first custom ROM.

I have been favoring the criskelorom myself; lots of features, reliable, etc.

On 2degrees. But that shouldn't matter - just flash the appropriate modem for telecom. You'll have to do that for all roms.

I've been running Cognition S2 with the SpeedMod kernel for a while, and the combo works great. Not too many changes from stock, and I'm easily getting 2 days between charges.

You don't have to worry too much about finding a Telecom modem with this phone. The original Galaxy S needed different modems because the Telecom version ran on different frequencies to the Vodafone/international version, and the phone hardware was slightly different. The SGS2 has quad-band 3G, so the hardware is the same for all networks in NZ.

Some people with the sgs2 are finding modems specifically written for the 850mhz band give better and more reliable performance.

The sgs 1 had different models for 850mhz and 900mhz; a simple swap of modem firmware was not all that was required to change bands; however the sgs2 is quad band as you say and does not suffer that annoyance. Still, picking the right firmware for the modem for your provider can reportedly improve results. Threads on XDA about it IIRC.

Thanks everyone for the input! Used your guide Brendan to get initial root. Thanks for that. I did wonder with the s2 being quad band 3g, the necessity to flash a modem separately but i can certainly understand that some modems may optimise performance on certain 3g bands. I did flash litening rom initially. but i'm slightly confused on something after the flash.

The original telecom wallpaper remained after the flash, which tells me it is a non wipe rom. Is this correct? I expected everything to be completely wiped. This surprised me, or have i done something wrong?

Pleased to help.

No, it simply means that particular rom did not replace that particular image. There are various messages on XDA about removing or changing such things, but my advice is to leave it - it's not worth the bother.

Some roms change all that stuff - I never had such a screen, as mine was a parallel import.

Cheers for that Brendan. I actually used your guide for the whole flashing procedure and gave me confidence to use Odin and havent used it often in the past. No probs, won't worry about things left over, I assumed it was a "bad flash" .

I can understand that.

But after you have flashed a few roms, you'll start to notice that sometimes they leave a boot graphic there sometimes. The better rom cooks clean it better.

You might get rid of it if you used odin to flash a stock samsung rom, but I'd leave that until you actually have a actual os problem as any flashing has the potential to go wrong.

No, not quite - it doesn't back up the EFS partition or the boot sectors (or the sd cards). As far as I know (correct me if i'm wrong). Just the OS itself and user settings.

It is imperative to backup your EFS before any custom roms are installed. Someone elses efs will NOT EVER work.

Speedtest.net results on Telecom XT

Averaging around 7000 kb/s down and 1600 kb/s up. Nawton, Hamilton.

I backed up my TiBu folder to the pc and was trying to find out which of the files relate to ShootMe which was a regular app reload for me, but is now no longer on the Market.

What is the name of the ShootMe file or files in this folder? Looking for "Shootme" but can't see it.

Is there another screenshot and/or video recording app just as good or even better?

Thanks in advance for the assistance!

I'm interested to know if anyone with a Telecom i9100T got a update for their phone on Saturday?

Reason is that my SGSII had some strange display issues that I wrote about in my review here

http://www.youtube.com/watch?v=3mf7IWenFIM

But on Saturday suddenly these problems are gone - the display is much better than it was on Friday.

Now I know that problems don't generally fix themselves so interested to hear if there has been an update?

Brendan:Some people with the sgs2 are finding modems specifically written for the 850mhz band give better and more reliable performance.

If in doubt, buy a contract-free SGS2 retail from JB etc - none of this worry about the T variant or any branding that way.

Anecdotal evidence in THIS thread is that the T variant works better with the matched modem due to the lower SAR which is apparently the only difference (relates to the radio although still quadband)

And I did, but I got mine from einfo.co.nz. Was cheaper than any other nz seller at the time, and they do honour warranty and etc.

Ah, yes that sounds familiar.

I;ll have the higher sar variant thanks, I think it'd have a stronger signal.

what is EFS? (is it the network provider settings?)

my phone only ever had 2 things done to it:

rooted with custom kernel (Chainfire)

then flashed with "no wipe" rom (cognition 2.1)

will this have changed the:
"EFS"
"boot sectors"

everything still works (network connection much better, but no longer able to do samsung dive phone tracking due to corrupted/malfunctioning IMEItracker)
