It doesn’t matter if you have an older phone or a newer one, you might be curious how long it takes to download a custom firmware. Although the answer may be slightly different for each device, it is easy to download a custom Rom in a matter of minutes. The actual time it takes to download a custom ROM will vary, depending on your connection speed and the size of the update.
Once you have downloaded the custom ROM, you must boot the device into recovery mode. The installation of the custom ROM will take some time, but will be worth it once it is finished. Your computer’s hard disk may be damaged or old, and it will take much longer to download. If you have a high-end computer that has a solid state drive (SSD), the custom ROM installation should take approximately three hours.
