Previously we have seen Galaxy S4 Mini and Galaxy S4 I9505 being updated to Android 5.0 Lollipop via CyanogenMod 12 Custom ROM. The official Android 5.0 Lollipop will take quite a time to reach such devices, although we had a good surprise in this category when we saw the Sprint Galaxy S5 receiving the official update of Android 5.0 Lollipop. There’s no telling if Samsung will release an official Firmware for Galaxy S4 as well. We do not know if that is going to happen anytime soon or not, till then you can enjoy Android 5.0 Lollipop on your device using CM 12 custom ROM. CM 12 is one of the best, or should I say the only option available for now and Galaxy S4 I9500 is also getting the CyanogenMod 12 Custom ROM.
If you are looking forward to updating your device to this ROM, just make sure that you visit the official thread once and read out all the known issues found in this ROM for I9500. The developer has mentioned that this ROM is not a daily driver so you’ll face a lot of issues in it. The source code is also there, so if you are into coding, then you can make this ROM even better on your own. In this article, we will show you How to Install Android 5.0 Lollipop CyanogenMod 12 Custom ROM on Galaxy S4 I9500. But If you are interested in Other ROMs, you can Visit our Custom ROMs section or you can install this ROM on your Galaxy S4 I9500 by following our tutorial below. This is not an official release from Samsung but a Custom ROM. You need to install a Custom Recovery on your device to install this. Your device must be rooted. Let’s go through the ROM features and early preparations and then flash this ROM.
1. This is only for Galaxy S4 I9500!
This custom ROM is only for the device mentioned above. Make sure that your model number matches the one listed above. To do so, go to Settings > About Device on your device and see your model number. Flashing this ROM on any other device will result in bricking it so make sure that you meet this requirement first of all.
2. Battery should be charged at least over 60%
Make sure that your battery is charged enough to complete the flashing process. In case your battery is low and your device goes dead during the flashing process, you may end up soft bricking your device as it won’t complete the flashing process.
3. Flash a Custom Recovery and Root Your device
4. Backup everything!
Just to be on the safe side, you may consider backing up each and everything from your Android device. This is highly recommended so that in case anything goes wrong, you still have the access to all of your data and you can restore it immediately. You may backup everything as listed below.
- Backup SMS Messages
- Backup Call Logs
- Backup Contacts
- Backup Media – Copy your files manually to your PC or Laptop.
- Backup EFS
- Titanium Backup – If already rooted, use Titanium Backup to backup all of your apps, system data and other important content.
- Backup Nandroid – If CWM or TWRP installed previously, otherwise skip this step and perform this at the end of flashing.
The methods involved in flashing custom recoveries, roms and rooting your phone are highly custom and may result in bricking your device, and has nothing to do with Google or the device manufacturer that is SAMSUNG in our case. Also rooting your device will void its warranty and you will be no longer eligible for any kind of free device services by the manufacturers/warranty providers. In case of any mishap we may not be held responsible. Follow these instructions to the letter to avoid any mishap or bricking. Make sure that whatever you do, you are doing it at your own responsibility.
