I wanted to upgrade my Galaxy 3 to Froyo but could not find how to do it. Couple of days of online research and I landed on this beautiful explaination. The linked page gives every detail and it helped me upgrade to froyo in just one day with some hit and trial.
The linked page gives all the details as to how to froyo your galaxy 3.
Here I would just mention my own experience of upgrading.
I downloaded ODIN multi downloader, ops file and the Froyo rom along with the default factory rom for my phone, just in case something goes wrong.
I factory reseted my phone, connected it to laptop and fired up odin, after lots of trial and error I am now sure that to get to the ROM download mode you have to press – Menu + Home + Volume down + Power on Galaxy 3.
It takes less than 5 minutes to copy the ROM.
And then it takes 4 to 5 minutes to restart and Voila! You have the colourful froyo.
A warning though… Froyo is not meant for low level hardware. At times Galaxy 3’s 667 MHz processor and 256 MB RAM fail to cope with Froyo.
Android 2.2 needs a decent hardware to run in full glory with all bells and whistles.
I first of all configured my office exchange email and suddenly I noticed all the things becoming dead slow and later a intense search online revealed that exchange has issues with Froyo. I did factory reset my phone more than 10 times and it was still the same.
I guess it was time to unFroyo and be back to éclair. The process was simple, only the ROM package was the one that I downloaded just for this situation.
One thing that I would like to confess is that after seeing Froyo with all its colors and menus I just wanted to go back to Froyo and was thinking how to go about it.
Today I did it again but this time I just copied the ROM with Odin without the factory reset.
All was going well but in some time the processes started to fail and I thought of rolling back to éclair, but just to be sure for the final time, I did a factory reset, installed improved email from market, configured exchange and somehow it didn’t slow down the phone,
Now here I am with Samsung Galaxy 3 running Android 2.2 Froyo with exchange email and the other 2 most popular apps Dailer one and Handcent SMS. The battery life is better and the interface looks really vibrant. At times the phone becomes slow but I can live with that as I have installed Advanced task killer.
Apart from all this I still am unable to root this phone on Froyo, It will be great if any of you could suggest how to root it. I have already tried super one click root and z4root.
This is so far my experience with Galaxy 3 has been satisfactory, although it’s my first android, I learnt a lot from it. I am looking for a new android and would buy a new one soon that can run Gingerbread without sweating itself out.
