I was planning to flash LineageOS on my Asus Zenfone 2 Laser, but I recently found out it is no longer supported on my phone. However, this guide explains how to build then flash the ROM on my device (and possibly root it), and I truly want to go down this path.

What is unclear to me a this point is whether it is "safe" to do so. More specifically:

  • Will I be getting security updates ?
  • Will it be safe to use banking apps with the custom ROM ?
  • What can happen if I lose/someone steals my phone ?
  • Should I stick with my bloated stock ROM ?

Thank you in advance for your help !

  • Does your bloated stock ROM get regular security updates? Is it safe to use banking apps on it? I would argue that this can only be determined per device, since some devices lose support from their manufacturers quicker than others due to popularity in sales. – Lucas Ramage Aug 12 at 15:10
  • @LucasRamage Perhaps you're right. On mine, the "About" section indicates "Android security patch level : feb 5 2018" (or something like that, because it's in French). Does this look reasonably recent to you? – mEEGal Aug 13 at 4:55
  • That's better than many for sure. – Lucas Ramage Aug 13 at 12:02

  • Will I be getting security updates ?

LOS team will keep merging in Android-side security patches, so each time you sync and build you get the latest they've merged, but kernel-side ones are up to you.

  • Will it be safe to use banking apps with the custom ROM ?

Root is optional on LOS - if you don't opt into that, the risk is low.

  • What can happen if I lose/someone steals my phone ?

With encrypted data and a good enough lockscreen passcode, your data will be secure.

  • Should I stick with my bloated stock ROM ?

Why did you ask this question in the first place? ;)

  • BTW, if you just want to get any LineageOS build or even any custom ROM, check here for older LOS builds, and XDA for more stuff. – Andy Yan Aug 12 at 15:04

    I think it should be noted that to receive the LOS patches, OP will have to update their source, rebuild and flash the updated system. They won't be available OTA – Namnodorel Aug 12 at 18:05
  • @AndyYan Thank you for your quick response ! Supposing that I root while flashing, do I have to be as careful as with any other rooted phone ? (I'm thinking of using automation for advanced customization) – mEEGal Aug 12 at 21:10
  • @Namnodorel Done. – Andy Yan Aug 13 at 0:28
  • @mEEGal It's rooted, no different. Handle carefully. – Andy Yan Aug 13 at 0:29
