How to Install Android 6.0 Marshmallow ROM using TWRP! [Failproof Method]

Having trouble installing an Android 6.0 Marshmallow or Android 7.0 Nougat custom ROM?  Our failproof method for TWRP has worked flawless for many phones on Lollipop but with Marshmallow you may still have FC (force closing) problems when installing a custom ROM.

UPDATE: This method is the SAME for Android 7.0 Nougat custom ROMs!

Well, after spending nights and days trying to find a new failproof method, I think I finally have found one that will install Android 6.0 custom ROMs without FC every single time!

The process basically involves doing a factory reset “after” installing ROM and Gapps, which fixes all types of force close problems when installing a Marshmallow ROM.

*Note – This is ONLY for AOSP ROMs, not for TouchWiz ROMs for Samsung.

Here’s the step-by-step instructions:

Step 1. You will obviously need your custom ROM zip file and Gapps file downloaded or copied to your phone’s storage.  For Gapps, I highly recommend using the Gapps here on our site.

Reboot into TWRP recovery then choose “Wipe”.



Next, choose “Advanced Wipe”.


Choose “system” only and swipe to wipe.


Step 2. Go ahead and install your ROM using the “Install” menu button.



Step 3. After installing ROM, also install Gapps.


Step 4. Next go ahead and choose “Wipe”.


Then swipe to do a factory reset.


That’s it!  For some reason if you don’t do factory reset after install Gapps, it causes havoc on some Android 6.0 Marshmallow.

But if you do it “after”, everything boots up fine and your Gapps also works well.  This will work on ANY Android smartphone or tablet.
