Install Official CyanogenMod 10.1 M1 build ROM for Samsung Galaxy S I9000 and I9000B
CM 1o.1 has now reached its first Milestone (M) release build and now you can learn how to install it on your device. Read all the instructions that I’ve posted in the lines below and you should be able to flash the new official CM10.1 M1 Build ROM on your Galaxy S I9000. Remember that this is a guide for advanced Android users.
The CM10.1 M1 ROM is great and it compiles all the best stock Android 4.2.1 and CM10.1 Nightlies functions and features. It is a Monthly release and it is more stable than the Nightlies builds. If you want to install it, then you first have to go over the preparation guide below. It will teach you what steps you need to take in order to make sure that the new ROM will install at your first attempt.
Here’s what you need to know before getting to the tutorial:
- Use this tutorial only with the Samsung Galaxy S model number I9000 or I9000B. Both versions of the ROM and the download links are listed at Step 1.
- Your phone has to be rooted and running a custom recovery image. The tutorial contains the instructions for CWM Recovery but these aren’t any different from TWRP Recovery. You can ask for extra help in comments.
- Use the custom recovery mode to create a full NANDROID backup of the currently installed ROM. It will set a ROM restore point and it can be used in case your can’t boot after installing the new ROM.
- Backup all your important data by moving it to your PC. The tutorial will tell you to factory reset the device, action that will delete the contents of the /system partition. That’s why you should choose to backup SMS, Call Logs. Use these tools: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore | AppBack for Android application. NOTE: the contents of the internal SD card will not be deleted by the new ROM install process.
- Save all your Contacts details using this guide HERE. It teaches you how to sync Contacts with Gmail.
- Enable USB debugging option from the Android developer options.
- Charge the phone’s battery until its power level goes over 50%. This will prevent the phone from powering off in the middle of the updating process.
- Don’t blame us if you lose any data or you brick the device. This is a guide for an advanced Android user.
- Use the comments section for any extra questions.
These were all the guidelines that you had to go over and now you should move to the next part of this post.
NOTE: In case your device is already running on a CM10.1 ROM then you can install the new M1 release without applying the ‘factory reset’ step.
