How to update Samsung Mesmerize with MIUI Custom ROM

Samsung Mesmerize LogoMesmerization is not what you will do after finishing reading this article as we will tell you on how you can power your Samsung Mesmerize device with the Gingerbread based 2.3.4 MIUI ROM. This update of ROM is applicable for all those whose phone is locked to the US Cellular as for also all those whose devices are open or locked to any other network. Basically the MIUI ROM is a non-stock ROM and is a customized built ROM which is developed by the Chinese developer community and comes with some cool features like great looks, speed and also comes with a whole new range of settings and is purely based on the latest Gingerbread 2.3.4 ROM. Proceed to the instructions if and only if your device is Mesmerize i500.

So, before we proceed to the actual instructions you will have to go through the pre upgrade instructions and then the procedure to update the phone with the simple instructions. Please note that we hold no responsibility if anything happens to your device as if you don’t follow the instructions then there is a high possibility that you may end up bricking up the phone for which we should not be held responsible. So, it’s always better to follow the instructions carefully before proceeding to the update.

Note: Please note that you will have to reconfigure the APN settings after updating the firmware to access the data services and the Internet services as all the Internet APN settings will be reset. You will have to contact your Service provider to get more info on the APN Settings or alternatively you too can make a note of it. Not to forget also configure the MMS Settings or take down the MMS Settings as this too will need to be re configured after the rooting process.Also, we take no responsibility if you download the files and apply the below procedure to root your phone.

  1. hi sir is any rom available for my galaxy fit in miui rom particularly

  2. Just tried to update my memorize, but it doesn’t ask where the update file is. It displays the white triangle with the orange explanation point with the green dude on it. I have followed it word for word unless I missed something with the Clock Work Mod.

  3. Here are the US Cellular APN settings you will need to add after updating to this custom ROM. If something is blank leave it blank. Also, you can find your MSID by going to SETTINGS>ABOUT PHONE>MORE INFO>STATUS. Your MSID is the number in the MIN field. This information helped me out greatly :

    Name: USCC
    APN: internet
    Port: 80
    Password: yourMSID
    MMS Proxy:
    MMS Port: 80
    MCC: 310
    MNC: 120
    Authentication Type: PAP or CHAP
    APN type: mms

    • I would like to also add that the link to the MIUI ROM Zip File you link to in this article is to an outdated version of the MIUI ROM. Being such, even if an individual tries to manually add in the above information they still might not be able to send/receive MMS picture or video messages. I couldn’t using this outdated ROM linked here. I however found success using the MIUI ROM Zip File I downloaded from this forum:

      I flashed that ROM, then added the APN settings I posted previously through an app I got off the market called, “APN Manager”.

      This newer ROM is quite nice too! A definite improvement from the older ROM posted in this article. The interfaces are overall a little different, a little more polished and more user friendly.
