If I do a Nandroid backup and then do a full wipe/reset and wipe the cache partition and dalvik-cache, will my Nandroid restore the cache's also?
The dalvik-cache will be rebuilt at next boot based on the applications present, so it shouldn't matter. You could clear dalvik now and reboot, and it would just regenerate for you. Some people do that to "clean up" every once in a while, I believe. I think the regular cache is similar, there shouldn't be anything there that can't be replaced (re-cached) when it's needed again.
Even so, I believe they do get backed up because my first boot after a Nandroid restore recently didn't take as long as it would have if the dalvik cache was being rebooted, but that's only an anecdotal answer.

Upon booting up via Vol. Down + Power, there are four options (fastboot, recovery, wipe cache, and simunlock). What happens when you wipe cache?
I just installed a new ROM (well updated), couldnt get it to boot as I was stuck on the custom boot screen, but after wipe cache it loads up?
Does this effect the functionality at all? Please help. Thanks
I believe this is a factory wipe, but is a dumbed down version, that does not wipe /sd-ext partitions etc. Just removes /data programs and user info, but won't touch any /system applications.
It is used to reset the phone without actually booting up the OS
Any particular reason why my ROM wouldnt boot up normally but requires a cache wipe in order to boot?

Soms roms will require you to wipe dalvik cache in order for the new rom to boot (conflicts can be caused), and wiping this cache would do it, however you can just wipe dalvik cache from recovery not this hboot menu.
For future reference when changing roms, especially when changing to someone elses rom (and especially especially when its a different base) you should be doing a full wipe
A full wipe is:
-Data (factory reset)
-Dalvik Cache
-Ext partition (although sometimes you can get away with skipping this one)
You should be able to wipe those three from both Amon-RA and Clockwork Mod recoveries.
NOTE: I am sleep deprived, so this will proberly not make alot of sense
I'm not that technical with the Android system (have worked with linux abit though)
Deleting the cache would remove any saved data from the system. These saved items may contain anything from images to which default program is loaded, to which widgets are loaded on the homscreen.
This is why after a new install the phone takes a little longer booting up, creating all the new files. If you need me to go into cache, use Google.
Another theory would be:
After an upgrade, some files and apps think that the system has changed owners, so their permissions change from read/write to read/only etc.
With this, some system files will become inaccessible, will be unable to be edited and so forth.
A way around this would be to "fix" the permissions of the data, changing the owner of the files allowing read/write permissions
Rom Manager has a nice little feature that allows you to fix permissions, and has come very helpful for me, with my switching to and from OD/Pinky, and restoring LauncherPro, which likes to FC at every restore -.-.
Ok, I don't know what I'm doing wrong, but I can never get rid of stuff completely.... like my Gapps are still there after everything and all I install is CM
I tried:
Wipe data/user settings
Wipe Cache
Wipe Davlik Cache
I also tried:
Wipe data/user settings
Wipe Cache
Wipe Davlik Cache
Format Data (in Partitions)
Format Cache (in Partitions)
Format Boot (in Partitions)
Format System (in Partitions)
I have tried both these options and I am still left with remnants of previous ROMs. Any suggestions? Do I have to load PC36IMG.zip and then root everytime to have a clean install? Seems a little extreme...

Clockwork 2.5 (previously), but I just switched to RA Recovery v2.2.2 still have Gapps on my phone... CM doesn't include Gapps right? I remember having to install them before unless something changed
Can't get rid of gapps, dude. CM requires it that they be there so they're protected files that you can't erase (unless you flash a new rom, which has all the gapps built in anyway).
I hope you like Google programs, because you are stuck with em

I love Gapps! I just suspect some of my FCs is because I had an older version of them. I am running CM7 now and I have the new GB Gapps but I thought it was odd that Gmail, Maps, etc was still on there before I even flashed the new Gapps
So to answer my original question, there is no way to completely wipe short of reimaging with PC36IMG and rooting again?
Run FORMAT_ALL from the post below. Once its down booting your new install, do not put your information into the setup wizard (just keep hitting skip). This will get you a clean install. REMEMBER FORMAT ALL WILL ERASE EVERYTHING ON YOUR PHONE (not sdcard/recovery/boot/s-off).

I'll give it a go, but according to Caulkin's thread all it is doing is what I did already! (wipe data, cache & format boot/system) I will try it out though. Thanks!
I did never try skipping the setup wizard... Hmm

This is the key, it will not restore the old apps, if you skip the wizard.
Well, I did it! Yippee!
I did the following this time around:
Wipe data/user settings
Wipe cache
Wipe Davlik cache
Ran Caulkin's Format_all.zip
Installed CM7 nightly
Funny thing is, it bypassed the setup altogether... I'm guessing because Gapps were finally gone! It brought me right to the home screen, I opened up apps and no Gmail, no Market, nothing! Finally!
So I rebooted Recovery, installed GB Gapps and I am running smooth as butter (No FCs yet!)
Thanks everyone! Especially bwcorvis for the link to Caulkin's script
Glad i could help
I'm currently running Synergy, and have been flashing nightlies every so often to keep up wit hthe changes and small errors that I encounter, hoping there's a fix in them, However reflashing a nightly every few days can be a pain as I keep having to reset all of my phone settings (ringtone, notifications, display, accounts, sms, etc...)
What is everyone's opinion of the best way to reliably backup your phone settings to easily restore them to a new rom after a flash?
I use Titanium Backup, but honestly I'm not sure what all the system settings are saved as, or even if that's a good idea as the way settings are setup might have changed from the las tbackup, and don't want to screw things up.
Ideas?
All you have to do is reboot into recovery, wipe cache and dalvik, and then create a nandroid backup of only the data. If you have an ext3 partition and your third party apps are stored there, then also select to backup the sd-ext and your android.secure (if you have paid apps). Now all you have to do after a clean install of Synergy or its nightly builds is to boot to your homescreen, bypass the sign-in stuff, and then remove all of the default homescreen widgets. After that, reboot into recovery, wipe cache & dalvik and then restore the aforementioned backup. When you reboot, all of your settings, data, apps and homescreens will be as they were on your previous installs.

thanks for the reply. just to be sure I understand you completely, using my current rom, would this be the proper order?
reboot into recovery (I use Amon Ra)
wipe CACHE, & DALVIK-CACHE
backup the following items: [ ]boot, [ ]system, [x]data, [ ]cache, [ ]recovery, [ ]wimax, [ ]sd-ext, [x].android_secure
wipe ALL userdata/factory reset
flash latest rom
boot to homescreen
remove all widgets/icons
reboot into recovery
restore nandroid backup created above
reboot normally
Also, as a side note, when wiping before flashing rom, I usually wipe ALL, CACHE, & DALVIK-CACHE, which are covered above. With the new Amon Ra, should I be wiping any of these as well before I flash? - DATA, SDCARD:.android_secure, BOOT, SYSTEM, SDCARD, SDEXT, DATA:battery stats, DATA:rotate settings?
Thanks for all the info! I appreciate it!
Include the sd-ext in the backup if you have an ext3 partition with apps on it. Other than that, you got it right. As for what to wipe before flashing, if I'm just flashing nightlies, I sometimes only wipe cache & dalvik, but I'm big on wiping EVERYTHING in amonRA's wipe menu EXCEPT the SD card before I flash a rom.
posting & replying via my EVO 4G
okay. thanks.
this is actually a follow up question, but the sd-ext, is that a special partition that I can setup that will expand the base storage of my EVO onto the SD card so I stop getting complaints about running out of space? And can that be setup through Amon Ra?
Hi all,
Somebody can tell me what are the results or issues when you wipe the different caches.
Because on the tutorials, they speak about "wipe cache", "wipe all", "wipe dalvick" and finally when I upgrade or install a new rom to avoid problem, I wipe data, partition an dalvick to avoid problem.
For a new rom, I can understand you need reinstall you apps.
But it's annoying when you update some rom.
Finally, the question is whose cache can be hold or wipe to avoid lost of installed apps and data when you update a rom.
Thanks for your answers.
Fred.
When people say Wipe cache or wipe dalvik, they mean wipe dalvik-cache. However if you wipe data, since dalvik-cache is in /data anyway, it also wipes dalvik cache.
Its wiping data that deletes apps and this is required as data and settings are more often than not, incompatible between different roms.
Its not a big deal if you backup with titanium backlup though and use the restore option "Missing apps with data"
Use sms backup+ or something to backup messages, then you just need to do your system settings again.
who can explain me how I can see where is my cache? on SD or phone...
For what do you need to know this?

I'm having issues with my ROM, and someone here suggested doing a nandroid backup, a clean install, then restore just DATA from nandroid.
But is this any different from just wiping SYSTEM and reinstalling ROM?
I was under the impression that a full wipe just wipes SYSTEM + DATA, whereas wiping SYSTEM just wiped SYSTEM.
I thought for a real "clean install" I need to wipe SYSTEM + DATA ("factory reset") then restore data with Titanium Backup, e.g.
Do the last one...
Restore Apps one by one. Don't make a nand data restore.

If your having issues with the Rom, a FULL Wipe, and Flash is usually your best bet. Try to avoid restoring to much Data. Especially system Data.
Use TiBu and restore apps only, and data only if you absolutely must, game saves, user apps that don't interfere with system on a per app basis. Use TiBu before wiping to backup your SMS and Call Log data as xml before wiping and then restore them the same way.
