I inherited a Galaxy Mini model GT-i5503t. It comes with Android 2.1 which is getting a bit old and unsupported, it is more than capable of running 2.3 and isn’t too hard to upgrade. This phone is also called the Galaxy 5 which is the same as the i5500 and i5508. These are the steps that worked for me to install CyanogenMod 7. Unfortunately you need to use a proprietary tool to flash a new Baseband image and ClockWorkMod to start with, but you can update to future CM versions without it. I’m not an expert in this so I’d recommend you redirect any questions to the XDA forums
(Google for download links)
- Odin Multi Downloader v4.28.exe
- Remove the SIM from the phone. Backup any data on the SD card, wipe it and copy the following files on to it:
- Find a Windows computer to download and run Odin Multi Downloader v4.28.exe
- Upgrade the baseband:
- Put phone into download mode by powering off then sequentially holding Volume Down + Centre Button + Power Button
- Start Odin, select One Package and the file AMSS-I5503TAJJP9.tar.
- Plug phone into computer via USB, it should show up in Odin (if not get the drivers from Samsung website), once detected click ‘Start’ and hopefully it will copy successfully and then the device will reboot.
- Install ClockWorkMod (CWM) with the same procedure as above but instead select the file ClockworkMod-Galaxy5-v0.7.tar
- When the device reboots it will start CWM. Wipe all the data phone:
- wipe data/factory reset
- wipe cache partition
- advanced > Wipe Dalvik Cache
- Install the roms
- install zip from sdcard > choose zip from sdcard > cm-7-20120702-MADTEAM-galaxy5.zip
- install zip from sdcard > choose zip from sdcard > hotfix5-cm-7-20120702-MADTEAM-galaxy5.zip
NOTE: This one is important! WiFi didn’t work without it
- install zip from sdcard > choose zip from sdcard > gapps-gb-20110828-signed.zip
- Once they’ve all installed, select the reboot option and wait for the first boot up which can take a long time (5 min)
- Done! It’s working great for me and I can now run apps that weren’t available on Android 2.1. If you’ve got any problems probably best to check out the XDA forums
I’ve been running this version of CM7 for 6 weeks now and I would definitely recommend it. I get better battery life, it’s more responsive, the phone no longer turns off daily (like it did with the stock firmware) and I’m having no problem running newer apps.
