First of all, Dear Admins and Mods, Please do not hate me if I have posted in the incorrect section

I have been reading the forum in XDA and following the steps. And I thought of making a fun and easy guide for clean installation of a ROM. Yeah why not. For this guide I'll take a Custom ROM.

Note: I always do a clean install just because I want to feel a new rom / device sensation after installation of the rom.

Fun thing to Remember: They (the world) says you need to fail before you succeed. But F-to_the-U-to_the-C-to_the-K them, you can succeed if you know what you are doing and if you are ok to fail a few times before your ultimate success. So Remember what I mentioned earlier in this paragraph. LOL. Just kidding. Sorry for the long post.

Prerequisites:

* Unlocked bootloader

* TWRP recovery installed (Version on my device 3.0.2-2)

* Nandroid backup of the current system and the same copied to the computer.

* A notebook/paper and a pen/pencil to write down any observations (this is really good if you mess up while trying the method of clean installation)

* Downloaded ROM and Gapps(My favourite is "pico" flavour).

* Phone atleast 50% of power remaining on the battery, USB Cable (for the phone) and a computer.

* Knowing that what you follow next is at your own risk :P

Before starting if you really like to know what these technical terms mean, do a google search on the terms and find out what they do and do not. I can say that I do not know many of the technical stuff but I google it up and ask people,

So here we go:

1. Make sure that you have fully understood what I have mentioned in the Prerequisites section.

2. Connect the device to the computer using the cable.

3. Restart the device using Recovery mode. (Power Menu > Reboot > Recovery).

4. Skip the informative screen from TWRP by mounting the partitions for R/W (just Swipe).

5. Check the device on the computer and check whether the storage is shown and accessible.

6. Let's start wiping. Hit Wipe > Advanced Wipe on TWRP.

7. Select all partitions and swipe to start wiping. (This will wipe the existing data / everything apart from recovery and bootloader)

8. Once completed go back to the starting screen of the TWRP.

9. Open the device partition on the computer and copy the downloaded ROM and Gapps packages to it.

10. On TWRP, click Install and select the required ROM, click Add more Zips and select Gapps package.

11. You can leave the device connected to computer or disconnect and connect the device to a charger.

12. Swipe again to confirm flash.

13. Once all are completed, reboot to the system.

14. The first reboot usually takes a good few minutes. (From all my custom and device manufacturer ROM installation experiences the longest was 9 minutes and a few seconds).

15. If the device does not boot up after 30 minutes and stuck at boot logo. This must be a cause of boot loop.

16. Once completed, set up the Google account details and once done do not install anything else, just reboot the device again.

17. Now once the device is up and runnnig, chase behind and hit it with some apps of your preference. lol just kidding. Seriously put some apps in :)

Questions? on the step 15?? Only happened once but never happened afterwards. I didn't do anything. Just repeated the steps from 1st point.

Any more questions: PM me :) or Google search, but make sure you add all the required details in the PM (such as what exactly happened or did before the error or issue) as I will be not always online due to work (Yeah I'm from a working class :D) But I often come online :)

Have fun :) Have a great Day :)

:good:
