How to Update Samsung Galaxy S GT I9000 with ICS 4.0.3 RC1 Firmware

Quick Pre Requisites:

  • Ensure that you have installed the MIUI Custom ROM as it is an MTD based ROM. Please note that if you are on any of the firmwares then you cannot update your device with this firmware.
  • Assuming that you are already on the MIUI custom ROM, you need to ensure that you have taken a backup of all your data so as to just ensure that if any data is lost or corrupted, the same can be restored easily. With the help of below mentioned tips, you can easily backup or restore the data.

SMS – Use “SMS Backup & Restore app”,
Contacts – Sync with the Gmail application,
Call Log – Call Log and Restore
Images, Songs, Videos, Files – Copy to internal / External SD Card,
APN and MMS Settings – Note down from the path “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names”

  • Disable all the Security Suites, Firewall tools and also the KIES PC Suite as these tools tend to interrupt the process of firmware update. Note that the device is left with the minimum of 60% battery charge so as to ensure that it doesn’t get turned Off in the middle of firmware update.

Special Instructions for Users on Custom ROMs:
If you have installed any Custom ROMs in your phone, then you need to first turn Off your phone to enter into the recovery mode. The recovery mode can be entered by pressing Volume Up Key + OK button, and holding both simultaneously press the Power Button. In recovery mode, select options “Wipe data/factory reset”, “Wipe Cache partition” and after this you need to also select “reboot system” so as to restart the phone.

Note: We will soon come up with an article which will help you in Rooting your Galaxy S on 4.0.3 Firmware.
So, let’s get started to the next page where we will see on what is the procedure to update with this firmware.

    After MUI installed, the installation is done correctly.

  20. When the next update arrives, will it be a fresh install or an update that maintains all apps, contacts etc?

  21. HI Neela,

    I updated my SGS GT-I9000 with RC1 one week back and it seems that it is working good but i noticed that when someone calls me then after picking the phone i can hear the caller voice perfectly but on the otherside the caller has problem to listen my voice. earlier i thought it may be network issue. but later i intensionally check it while calling from my other mobile/landline then it confirms that there is some issue in RC1 of ICS.But when the same caller again calls me immediately then there is no such problem on either side.

    Now intended to go for RC2.1 but while the reading the comments it feels that it is not the good time to go ahead for RC2.1.

    So I request you to please advise/suggest what should be done or any fix is there for this problem.

    Thanks

  22. can you explain me how i install this update.my phone on gingerbread 2.3.4 xxjvp

  23. Hi,

    Is there a way to get notification like the numbers in the red balloon on the msg and phone in home screen. I can’t seem to find option for it. Also is the better notifications for the lock screen like in 2.3, I’m only getting a small text symbol in the notification bar.
    Thanks

  24. issues i’ve found with ics 4.0.3 rc1…
    No radio

    Third party music app like mixzing force closes all the time
    No labels when browsing through video files and images in gallery.

    all in all this rom has to many foce closes,i hope they get rid of most of this bugs in the next update…

  58. Hi Neal,

    I am currently running CM7.1 Rom on my Galaxy S, will I need to apply the MIUI Cutom ROM prior to the ICS update?

  59. i flashed it it works great mostly every thing is working fine. huge battery improvement
    but there is some minor bugs i want to share
    first the video recording doesnt reach the 30 fps its at about 23fps which you feel that’s it little bit laggy
    second when i tried quadrant to see its rating (standard quadrant ) there were great performance for the fps in every test but when it came to the rendering of the moon revolving around the planet the graphics were glitchy and very low fps at about 15fps and may be thats what is causing the video recording to be bad on 720p

    when i found any other thing i will post it

    thanks NEAL
