[Q] Twrp recovery -- do I also wipe system before flashing new rom?

[WilDip]

Hello. I have backed up my stock rom and would like to flash a new custom rom. Team Win Recovery is all new to me as I used clockwork recovery and Amon RA on my old evo 4g. Before I flash a new rom, I know I'm supposed to wipe cache and dalvik, but do I also wipe system? Thank you for your help in advance.

If you're flashing a different ROM all together, then I usually do Factory Reset, Cache, Dalvik Cache. (in that order)

I don't know that the order matters, it's just my way of doing it, and I've never had any problems.

Thanks for your quick response. Gladly appreciate it! But there's also an option in the wipe menu to wipe "system". In the wipe menu, there's: cache, dalvik cache, factory reset, battery stats, rotation, system. I wiped cache, dalvik and battery, anything else I neeed to wipe before I install a custom rom? In clockwork recovery, all I used to do is wipe data, cache and dalvik.

Yes, when flashing a fresh ROM wipe EVERYTHING, including system. I usually wipe a few times just to make sure I'm starting fresh. I haven't used this super wipe but you can also check this thread

Edit: I don't usually worry with wiping battery stats or rotation

Got It

Thank you. I wiped everything and performed a factory reset.

You don't need to wipe system. Any decent rom out there will wipe the system for you before the rom flashes.

If I'm not mistaken, I believe that the factory reset wipes system anyway.

No factory reset does not wipe system. Also do not use super wipe zips. They are bad for you

Factory reset wipes the data partition. It does the same thing as the factory reset within the phone settings. If you wipe system, it completely wipes out the OS, and there will be nothing to boot. Of course you can still get back to recovery. When you flash a rom, by default it should wipe the system for you and replace the system with the rom you are flashing. There may be a case where you are flashing an incremental upgrade, which will not wipe the system.

The reason you do a factory reset (data wipe) when flashing between roms is because settings and other stuff that was saved on the data partition may not be compatible with the rom and cause issues.

Based on what?

Based on what developers have said. Super wipe originated from a CWM issue back on the EVO 4G and people never seemed to of forgotten.

The issue was with cwm not superwipe. The superwipe created for this device works fine.

 

[Spyderekz]

the issue was with cwm, the superwipe was made to combat that issue. a good dev will set his rom to wipe system. all a user has to do is factory reset in recovery. Superwipe is a unnecessary step and could be bad for the phone if its corrupted or the person who made it did it wrong.

So if i wipe the system, i can still get back to recocery?

Yes. A system wipe doesn't affect recovery. It just wipes the system partition on your phone. The recovery partition remains unaffected.
