    Hi, I followed this guide exactly and it worked fine. However, when I rebooted the phone would not turn on and only the back camera light came in when the power button was pressed. What could have caused this as I now have a new phone that is not bricked!

    Thanks.

    Is this for nexus s 4g as well?

    Nope. There isn’t an official update for that yet.

    You can in fact do a whole ROM update to go directly from 2.3.1 to 4.0.3 without updating to 2.3.6 in the interim. This is what I did on my new Nexus S and it worked a dream first time. The ZD3PyN0t.zip allows this without issue through the built in bootloader. No root required and all stock :-)

    I did read here http://www.zdnet.co.uk/blogs/communication-breakdown-10000030/google-stays-quiet-on-nexus-s-ics-android-battery-fix-10025093/ that there were 2 ICS updates available, a 125MB one that seemed to cause a lot of issues, and this was the OTA one, and the 160MB listed here which seemed to be more stable. I’ve applied it to my Carphone Warehouse sale Nexus S without the mid-step, and it seems OK, but i guess only time will tell if there’s any faults that don’t show up in the first day or so.

    Awesome run through Rav, much love!

    In case anyone’s interested, in the week I’ve been running ICS on the nexus S, no problems so far, and far from poor battery, I get very good battery. I tend to only switch on 3g or wifi when needed (as I do on all my phones), but I’m easily getting about 2 to 3 days on average use, so certainly for me, no disadvantages at all.

    Thank you great guide worked exactly as you said

    I bought my Nexus s from Carphonewarehouse on Monday, last one available in store for £199.95.
    Yesterday I updated it to ICS, as above.  Put it on charge last night about 10pm, with 15% battery, left it all night, until this morning about 7.30am, and it had 63% battery.  I used the Samsung charger that came with the phone, so surely it should have fully charged over night.  Is this an ICS issue, or a Nexus S issue, or a stock charger issue?  Any ideas?

    I did find that the phone was quite slow to charge but it got quicker after a few days. But if you left it overnight it should have been fully charged. Very strange.

     A little bit better laat night, I used my HTC charger (a bit more umph 5V/1A vs 5V 0.7A).  On charge from about 10pm, decided to turn it off this time, this morning 5 bars on the battery display before turning on.  But when I turned it on, the battery status said 83% charge.  Perhaps the phone is training the battery, getting to understand its capacity.  This is the only explanation I have.  We’ll see how it goes over the coming days.

    Excellent run through—-applied it to my nexus s in January but had to revert to gingerbread  last week, but only because, very occasionally, the phone would not ring on an incoming call.I stress this only happened only very occasionally,the battery life was excellent as was everything else about it.but how can you trust a phone that may not ring .very sad really.I shall wait until a newer update comes along.
