[Q] Installing new kernel and dalvik cache

I just installed a new kernel and afterwards read about clearing the dalvik cache before installing kernels. Since I never did this should I clear it now, or do I have to clear it and then install the kernel?

clear then install

Is this the same thing as "cleaning" the dalvik cache using Titanium or do you actually have to delete the entire cache folder?

To be on the safe side i do it both in Titanium and then when i am in Clockworkmod, I do it in the advanced section too - by the way if you do not have partition done on your sd card u will see an E: error message. You can ignore that.

Thanks alot .... I did it the way you suggested and am rebooting now. I appreciate the help.

For kernels, you want to delete the cache partition, kernel stuff usually isn't help in the dalvik cache. On Amon_Ra style, it's wipe cache. On CWM I think it's wipe cache partition (Don't know, have not used CWM in a while).

Cleaning in Ti only deletes unneeded files. Do this after you uninstall an app or two. Wiping in Recovery clears it out completely, so you'll have a longer next boot time while it's rebuilt. You only need to wipe it when changing to and from one of King's with HAVS.

So I don't need to wipe when updating Chads incredikernel?

You should always wipe caches when swapping kernels, even it its switching kernels from the same dev. It takes like no time to do so why not? I've forgotten to and usually it makes no difference. Sometimes its just forced closed's until I can restart and do it right.

Is it necessary to wipe data and cache data when I restore backups

Is it necessary to do a cache, data and delvik wipe when I am restoring a back up?
I always have back up of different ROMs and very often I try out new ROMs. I always wipe everything but is it necessary?

Actually, so do I but I'm not sure whether we need to either! I just don't want to take a chance that a residual file screws something up...

If you are restoring from a nandroid, no it is not needed. The backup restores EVERYTHING data/cache/davlik/kernel/etc...

That's good to know.
I am restoring from the nandroid backup.

I've gotten alot of errors before when restoring a sense rom from an aosp without wiping... And by errors I mean it restored fine then was unusably buggy...

Just go into recovery wipe data and cache then restore. Its not rocket science.

No, it's not rocket science, but that's not what the OP asked.
It was a valid question: is wiping needed when restoring a backup, or is it a superfluous step? No need to offer a condescending non-answer.
For what it's worth, I don't wipe before I restore a backup and have yet to run into an issue. That's not to say I'm right; just that it hasn't yet caused me headache.

[Q] Noob ?

Whay exactly does a full wipe consist of? Using RA 2.3 recovery.

I usually wipe system, cache, and dalvik that way I keep all my dl app but some wipe data also. U can wipe boot as well.

A full wipe, in preparation to flash a new rom would consist of wiping:
data/factory reset
cache
dalvik cache
boot
system
I always wipe everything 2 or 3 times. I also flash Calkulin's Format All after wiping all of the above. That might be overkill, but it makes me feel better before I flash a rom, lol. You get a completely clean start.

What would happen if i wiped everything and rebooted? not that i wanna try it or anything just curious

My definition of a full wipe using amon RA is EVERYTHING in the wipe menu except the SD card and when I flash a different rom, I wipe everything on that list with the exception of the card itself. Technically speaking, however, the list that k2buckley posted is correct.

If you tried to boot after wiping what I mentioned, you will either hang at the splash screen or it will boot you right to fastboot (not sure really though, as I've never tried, but it wouldn't boot, for sure). Since it wipes system and boot image, there would be nothing installed for you to boot into. Btw, I would avoid trying that lol.

That's crazy. Wiping everything like that is over kill. No need to wipe data as its all the apps that uve downloaded from the market. The only ones really needed are dalvik, cache, boot, and system. And I've only ever had to do it one time then flash a rom and it works everytime plus I have all my data and apps there still

He asked what a FULL wipe was. Not if it was necessary or required. And not wiping data when going from one rom to a different one (not an update of the same rom, but to a totally different rom) has ALWAYS left me with weird issues, such as wake locks, cm Widgets on salvage mod, reboots etc.
Oh well, we all have our own methods and rituals for flashing, lol. I will stick to my methods, and everyone else can use theirs.

I'm guessing u know this but have u ever looked at ur data folder with root exployer or what ever. The app folder might have 5-6 apps in it and the app-private folder holds the apps u dl from market. So wiping it in recovery makes little sense. I've flashed plenty of different roms without wiping data and never had a problem. Plus on an upnote all ihave to do is flash the roms and gapps if needed and restart and that's it. No need to sit there for an hour restoring apps or settings

(Request) cwm flashable super wipe script.

Looking to see if one of the awesome devs here can whip something up. On previous devices we seemed to have some flashable wipe scripts that would do a thorough job of cleaning the device before a flash. For instance one could wipe cache, dalvic, data, and system, as well as do some sort of disc alignment in one flashable script. It would mount the proper partitions and ensure that the device was clean for a fresh install. With all the choices between aosp, ics, and jelly bean roms, this may help alleviate some of the questions about what,and how to wipe properly. I for one would love to see a similar file for this device.

If people have any questions about how to wipe or what wipes are necessary for there particular flash I believe they should read more and learn about there device inside and out so they won't need to ask such questions and can fix problems themselves, not spoon feed them a do all script that they have no clue what it's doing or afterwards if something goes wrong they will have no clue how they got there or how to fix it. My 2c.
I do see your point of making it easier for power users however, but in reality most fresh install require 3 different wipes all located right next to each other(twrp) and dirty installs even less, I don't really see that 10 seconds it takes to wipe the phone clean to be such an issue, but that's just me. Not trying to argue or flame, just my thoughts.

I don't know about disk alignment but this will do the wiping for you.
I know this is obvious but don't run this from the internal storage. Only do it from external.

No clue on how they got there or how to fix it? It is a wipe script, not a magically fix and load custom stuff on there phone script. Again if you cant help then don't post.

Does this wipe internal storage? Based on your instructions I am assuming so.

That's the problem to use a script to wipe data also wipe your internal sdcard. The only safe way is to use a custom recovery that doesn't wipe /data/media. I can look into it and see if it can be done without wiping data/media but no promises...
The link above just deletes the directories, including data so i wouldn't recommend using that if you want to keep your internal sd contents.

Here is the one we used on the hercules, maybe you can try to make it work on this device.

You could have it backup /data/media and restore it after the wipe. Of course the better way would be to just skip it but I am not sure how to do that.

OK here is a new one that will wipe data but not /data/media.

Edit: It still wipes cache, system and dalvik just to be clear.

So it wipes data, system, cache, and dalvic. I was only concerned because i thought your original one wiped sdcard.
Edit. Did you see the file i posted from the last script i used?

Yeah it wipes all of those but doesn't wipe /data/media. The original one did wipe all of data so I fixed it to skip media.
I must have missed that post but to be honest I am weary of the disk align thing. I have never done it and have never had a problem so I likely never would use it.

Cannot open gallery

Hey everyone,
I recently flashed jedi invasion 5 rom to my tmobile galaxy s3. For some reason I can't seem to open my gallery, it tells me I don't have enough space, however, I have plenty of space in both my internal memory and my 32gb sd card. Any help would be great, thanks

What were the steps you took in flashing the rom, we need a little more info to help you out.

Go into manage applications setting and clear app data for anything that has to do with media storage & gallery in the system apps list, then reboot. That may or may not help.

Sorry about that. So prior to Jedi invasion rom i was rooted with some stock rom. I basically went into clockwork recovery mode, i wiped user data, wiped cache, wiped dalvik, and then i flashed the jedi invasion rom. I have actually redid this process over a few times already, still however the gallery fails to load telling me that there isn't enough space. I have tried formatting my sd card, cleaning out my internal storage, clearing my gallery cache... all of those didn't help fix the issue either. Although, when i downloaded a different gallery from play store, that worked just fine.

It is strange... By wiping system do you mean wipe data/factory reset in recovery mode? Or is there another way you're referring to that does a more, for lack of better words, cleaner wipe?

I can't remember where it is under on CWM I'm a TWRP kinda guy. I think Mounts and Storage, and yes is't where all the system files are (the ones that aren't delete-able without Root Access). Like gallery and such. My guess some bad left overs from the other rom/gallery/camera aren't compatible with the rom/gallery/camera you have now.
