What is Custom ROM?
When we buy a phone it always ships with a veirsion of operationg system. And the operating system that comes with your phone is called stock ROM. And custom Rom is the opposiete of stock ROM and it's a totally standalone version of the operating system.
Why we need to flash Custom ROMs?
- Upgarding to a better version of Android OS
- Improve the performance and efficiency
- Frequently update
The reason why most android users flash a custom ROMs to their phone is that they want to get a better version of Android OS prior to the official version or the version of their phone's OS may never be released officially in this situation they may find the better version for their device by flashing a custom ROM.
Since there is no useless garbage and the kernel is optimized by the developer the custom ROMs are often faster and more efficient.
After flashing a custom ROM there will be more frequent updates in order to fix bugs and introduce new features.
After you make clear of the custom ROMs you can flash a custom ROM by using ROM Manager APP. ROM Manager is used to flash custom ROMs without losing the phone's functionality. This app makes it easy to change the ROMs and experience the new version of android through the simple interface provided.
How to flash a custom ROM via ROM Manager

- Tap on the ROM there will be a popup menu which has two options: Backup Existing ROM(if you have not backed up you should do here) and Wipe Data and Cache (Please note: this wipes the internal memory but not the SD card data ) if you do not upgrade from the stock ROM you should do this.
- Just follw the rest tips and the new ROM will be installed.
Before flash a custom ROMs via the app a rooted device is needed. If your phone has not rooted yet I highly recommend you have a try on KingoROOT which has two versions: KingoRoot Android (PC Version) and KingoRoot (APK Version) and offers the easiest and fastest Android rooting experience for almost all devices and has the highest success rate.
Search ROM Manager from the Google Play Store and download it to your phone. There are three parts used most on the menu: RECOVERY, ROM MANAGEMENT and BACKUP AND RESTORE. You can backup and restore as well as flash new ROMs in one interface.
If you want to fully backup your device we recommend you try Nandroid Backup which is also used on rooted device. Before backup we need to install a Recovery Image Specific to your phone.
This recovery image contains a boot loader which will replace your original boot loader. The boot loader allows your device to run Nandroid backup, restore commands outside of the OS and install ROMs. Since the OS cannot back itself up fully while running, ROM Manager will reboot into this boot loader to perform Nandroid operations.
You can backup just by clicking the "Backup Current ROM" and your phone will restart and the full backup will be restored onto your SD card. After the backup is done you can find the backup files on your SD card in the clockworkmod/backup/SOMEDATETIME directory.
Before you find the custom ROMs you should use your phone model to find your wanted Android version on Google. You should be aware that each ROM will be based on a specific Android version.
Download the ROM image which is usually a zip archive and just copy it (but not unzip the .zip file ) into the root folder of your SD card.
The process of installing new firmwares or low-level system softwares in general is called flashing.
The process will take you 5-10 minutes to install everything and will take another 10~20 minutes during the first boot. So do it in your spare time. After all these done you will find your phone run in a new ROM.
ROM Manager is a must-have app for the Android users. If you are looking one app to flash a new Custom ROM the app is worthy to have a try.
