Guide to Update Redmi 1S to Android 4.4.4 with CyanogenMod 11 ROM –
Step 1 – Install CWM recovery (For Redmi 1S Indian version). Download here.
To install CWM on Redmi 1S, download signed_cwm_update.zip and rename it to update.zip. Transfer the update.zip to the root directory of phone. Go to Updater app, press menu button and then click “Reboot to recovery mode”. Choose English, then select ‘Install update.zip to system’ and select Yes. Now go back and reboot to system.

Step 2 – Make sure your device has a microSD card inserted, 2GB one would be sufficient.
Download the required files:

• cm-11-20140920-UNOFFICIAL-armani.zip (CM11 R3 based on 4.4.4) – 230 MB
• gapps-kk-20140105-signed.zip (micro GAPPS) – 83 MB
• Or gapps-kk-20140606-signed.zip (Full GAPPS) – 150 MB

Then transfer both the above files to the root directory of your external storage (/sdcard1).
Step 3 – Flashing CM11 ROM on Redmi 1S using CWM Recovery

• Reboot into CWM Recovery (Go to Tools > Updater > press Menu key and select ‘Reboot to Recovery mode’)

Take a Nandroid backup of your device – It’s highly recommended to take a backup via CWM in case you want to revert back to MIUI. To do so, go to ‘backup and restore’ and select the backup option. The backup includes MIUI ROM, user installed apps and their data and your settings. The backup will be saved on your external SDcard in the “clockworkmod” folder. Note: If you get an error while taking the backup then first perform a factory reset using CWM and then take the backup again. (This won’t backup your installed apps though).

• Select ‘Wipe data/ factory reset’ and confirm to wipe.
  
• Select ‘Wipe cache partition’ and confirm.
  
• Go back and select ‘Install zip’. Select ‘choose zip from sdcard’ and then choose the ‘cm-11-20140920-UNOFFICIAL-armani.zip’ file and install it. Similarly, install the gapps.zip. (Make sure to flash the CM11 ROM file first).
  
• Now go back and perform a Wipe data/ factory reset and Wipe cache again. Go to Advanced and ‘wipe dalvik cache’ too.
  
• Reboot your phone by selecting ‘reboot system now’. That’s it!
  

Your phone should now boot up running CyanogenMod custom ROM.
