Root Flash ROM Wipe All Neccessary Stuff

[TrevorX5J9]

Is there a way to wipe just the required system files, leaving behind apps and user data? Isn't the ROM only replacing certain parts of the system, not everything?

wipe davik and cache should do it.
I personally use Titanium Backup and do a complete wipe Before installing a new rom.
You are asking for trouble if you take short cut.

Everyone usually Factory Resets though. I want to go from stock 5.0.1 to Cataclysm. Dalvik and Cache only? Wouldn't I also want System?

From Stock to a custom rom wiping davik and the cache should be fine.

It really just depends... If you notice any odd behavior or apps and etc Force closing on you after flashing Cataclysm, then you'll want to perform a Factory Data Reset (which I'd recommend anyway) and that should resolve any issues that you may incur. Just make sure you have everything backed up and a current nandroid before moving on.


From the Cataclysm thread -

How should i install Cataclysm?
- Do a Wipe/Factory reset and then flash. Strongly suggested to update to latest recovery.
- Should be safe to dirty flash new releases over the old ones unless android version bump.

Alright I'm going to make a nandroid, I'm familiar, I just hate wiping because my WiFi is complete crap. I'm just going to wipe System and Cache. Should that be enough?

Wiped System and Cache, Cataclysm tells me updater zip crashed or something???

Do you know what the exact error through recovery was?
I'd have to see the output from the recovery to try and help with better answer.
I think it's because you wiped the system partition. So follow these instructions and you should be OK.

Quote from cataclysm -
- Don't wipe system. Don't mount system. If you did, reboot again to recovery before flashing.

If you haven't already, I'd also recommend updating your N5's bootloader, radio/modem and recovery to the newst versions for 5.0+ compatibility. (TWRP 2.8.1 is a good one)
You can either fastboot flash the newest bootloader, radio/modem or TWRP through your PC or you can also find all the files in a flashable zip that you can flash through your current recovery.
If you haven't, I would make sure that you're updated in these areas first.

If you need any help flashing the bootloader, radio or TWRP just ask and hope this helps
