How to do a clean installation on my device with twrp??
wipe Delvik cache, System, Cache and Data and flash your ROM

Hi all, I'm new to android and just receive my HTC One X and have ARHD custom rom installed. I read somewhere stating that when flashing roms, I have to clear cache and dalvik cache. But when I did so, I received this error.
dalvik cache e:unknown volume for path [/sd-ext]
Read somewhere that this is normal, is it? just want to confirm.
Also hope some of the veterans here can assist, when installing a kernel/ rom/ radio what do I have to do? I've read this post and am unsure if this is correct.
Rule of thumb for flashing and wiping - in recovery mode
flashing a rom - wipe data, cache partition, dalvik cache, format /system
flashing a kernel or a theme - wipe cache partition, dalvik cache, format /system
flashing a radio - wipe cache and dalvik and format system

my ROM is clearing dalvik-cache during the installation process. No need to do it manually.
Wipe:
System
Cache
Dalvik
Install:
ROM
GAPPS
Format "sdcard"
REBOOT
Yes it will.
Updating aokp for example, the aokp updater told me about the update but is it the same process as installing for the first time? Will I lose my apps and everything or does it only wipe cache? What step in roms delete everything, format data or factory reset or both?
Cheers.
No wipe needed if updating.I recommend wiping cache and dalvik-cache for good measure tho. And you have to reinstall gapps after the rom as well.
When a wipe is needed you want to select factory reset. Never select wipe/format data as it'll wipe the internal storage too.
Then what about...
If you are already on AOKP and doing an update:
1. Make a nandroid (backup in CWM)
2. Format /system
3. Wipe cache
4. Wipe dalvik
5. Install new ROM zip
6. Install gapps
If you end up with issue or coming from another ROM, do this:
1. Wipe data/factory reset
2. Format /system
3. Wipe cache
4. Wipe dalvik
5. Install new ROM zip
6. Install gapps

Isn't a Format/system wiping the apps? Or does that not affect the apps? By format on my recovery it says formatting the sd card deletes everything (on TWRP).
Cheers.
hellooooo.
i've got some issues.
I did every point(without dalvik cache) in instruction, I mean:
1. wipe data
2. wipe cache
3. install zip from sd-card
4. wait untill flash
5. wipe data again
6. wipe cache again
7. wipe dalvik cache
8. Hit reboot and enjoy

then I flashed gapps light for 10.1... and I haven't Google Play Store, why? ((
(sorry for my bad english xd)
edit:
if I wipe my dalvik cache and then I would like to restore my previous rom (backed up 1week ago)... would be everything okay? without bugs?
i'm asking about it, because I dont know what is 'wipe dalvik cache' xd
Try this method.
1. Boot into recovery
2. Wipe data
3. Wipe cache
4. Install zip from sd-card and wait till it flashes
5. Wipe data again
6. Wipe cache again
7. Install gapps from sd-card
8. Wipe cache after flash
9. Wipe dalvik cache now
10. Hit reboot and enjoy
For anyone that doesnt know,when you get bootlooped for flashing a bad zip dont erase data just reflash the rom and wipe cache and dalvik cache
