Big words of encouragement! And does "fall(ing) hard" have a 90% chance of occuring or a 5% only? That's what I'm asking from this post. If it's actually worth flashing a custom ROM or currently there are too many obstacles in front of what I'm trying to do
First off, the instructions provided by the ROM developer is a simplified list of objectives. You will have to figure out how to go about each and everyone of them if you have not gone through the process before.
Second, the ROM dev might be missing out crucial installation info in his instructions. You will need to have flashing experience and/or an idea of your end result in order to find out if that is the case.
Third, many custom roms have quirks in the installation process not accounted for by the rom developer. You are going to have to read through the rom thread to find out what they are and how other users of the rom managed to work around these issues.
Last but not least, you will want to establish a course of action if something goes wrong. Refer to unbrick guides for your phone in the Guides section for your phone on XDA.
With a custom ROM installed, you no longer receive official updates from the phone manufacturer or your cell carrier. The ROM developer may instead (at his description) provide updates for HIS custom rom to users where available. These updates are not guaranteed to not result in loss of functionality or outright soft brick.
Most cases of bricking are soft bricks which can be fixed by following the appropriate unbrick guide. And then you will have to re-do everything whatever you were trying to do. In the case of a hard brick you will have no choice but to send it to the manufacturer and hope they will be willing to fix it for you (physical bootloader chip replacement)
As long as your phone is not hard bricked, you can always follow the unbrick guide to flash back the stock firmware. If you are back to stock firmware, you will receive official updates from the manufacturer and/or carrier again. Keep in mind none of these official updates remain on the phone if you install a custom ROM.
Installing a custom ROM worth it? Totally depends on you.
