[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.

Help: New ROM = Force Close Everything!

Hey guys so I just flashed this rom on to my phone:
http://forum.xda-developers.com/showthread.php?t=1175842
It looks amazing, but how do I get it to work without all the force closes?
Nils says this in the thread:
"If you choose to flash over without a wipe and have lags, FC's, things missing, or things just don't work right then flash again with a complete wipe"
What does he mean by a complete wipe? and how do I do this? Thanks everyone!

Use Rom manager(found in market) boot into recovery. You will see 2 wipe options Data and cache partition. Wipe both 3 times each. Still in recovery click on advanced. Wipe dalvick cache 3 times. Then install rom.
Full wipe

You don't need to wipe each thing 3 times; it's the same code executing, so once is perfectly fine.
anyway, like MagnaCore said, a full wipe is:
Factory Reset
Wipe Data/Cache partition
go to advanced
wipe system
wipe data
wipe dalvik cache
I think that's where they're located; can't remember 100% for sure tho.

I'd do what the poster above me said, and /system is actually in the "mounts and storage" menu in recovery.

Ah that's right couldn't remember where it was for sure. Thanks for the correction.

No problem. Always a good thing to remember to wipe,since it isn't covered by the wipe data/factory reset option. IMO it's better to be more thorough with WHAT you're wiping as opposed to doing it multiple times..

Exactly.
I usually do the factory reset, wipe data/cache, go to mounts, wipe system/data/cache again, and then go to advanced and wipe dalvik cache; just to make sure I got everything.

Bmw, you have .92 hboot, yes? You'll find force closes with this if not.

I think there is something to multiple wipes!

I was on here late last night and was looking thru a thread and someone said when you wipe cache and dalvik you should do so several times. I had some issues with my phone the other day. Evidently my phone doesn't like being severely undervolted. Thank God for nandroid. Also system tuner pro was giving me fits to. So I decided to reflash my rom. I had been running faux kernel with the skyrocket mods. So I wiped data/ reset twice then wiped cache and dalvik twice . Flashed rom and fixed permissions twice. My phone is now smoother then its ever been. I'm not using fauxs kernel either. So the moral of the story is next time you flash or wipe. Make sure you do so a few times. Hope everyone had a great new year! !

Yeah I use to only wipe things once, but the past few roms I've been wiping everything 3 times with no problems that I would run into after only wiping once. I've also read a few people saying that after you wipe everything multiple times and flash your rom..flash the rom again directly after...not sure what exactly that does if anything, but a few do it. If anyone knows what exactly that does flashing the rom twice in a row please let me know. Not possible to have too many good habits if your a flashaholik lol.

Is there a superwipe script like there is for the sensation and the amaze it seems to work great. I always get a clean flash and it works great gives you one thing to do before you flash a rom and a clean install.

Ive never wiped cache and dalvik when flashing roms. Maybe I should. Can I do this now after the fact or would this erase all my data?
When exactly do you wipe dalvik and cache? before and after a new rom install?

I guess if your not having any issues then you don't need to worry about. I always wipe dalvik and cache in recovery before a flash a rom or kernel or a theme.

You are lucky if you don't have any problems. You suppose to wipe dalvik and cache partition before flash/install a new rom. Wipe the dalvik and cache partition in recovery shouldn't erase your data, but if you don't have any problems then I guess you're ok.

Lawl. Funny thread.

[Q] Questions about wiping before flashing

I was recently on TDJ's Darkside Rom. I decided to flash the Infamous Resurrection. I followed the instructions Wipe Flash etc. However when I rebooted almost all of my apps are still there and then they start force closing like CRAAAAZY. I know I can go and "fix permissions" however I want a FULL CLEAN INSTALL. The other rom was giving me weird issues and I am ready for something else. I use TWRP. What's up? How can I do a system wipe and cache wipe and still have most of my apps? This doesn't seem right. How can I fix this? Thanks sincerely for any help given .

You need to write your data, or "factory reset", because your apps and stuff are kept in the data partition, not the system partition. Just do the factory reset, wipe system, cache, and dalvik, and then flash again.

[Q] Settings stopped working unexpectedly

I'm using FullySamsung 1.0.1. + FIX. As soon as I select Settings> Language and Input, Settings panel crashes. Before flashing the FIX zip, I'm able to access Language & Input from Settings panel. Any suggestions is highly appreciated. Do I need to clear Dalvik Cache after flashing the base ROM and before flashing the FIX?

Go into menu then manage apps and see if you can clear cache for settings there then try to reopen. If that don't work try flashing the fix again with wiping cache and dalvik see if that solves it.

Thanks for the reply Reinaldo. Tried rebooting into recovery and first wiped cache then cache + dalvik. Then wiped dalvik cache. Then flashed the fix again and reboot. Still the same issue with settings panel. Any more suggestions? Am I doing something wrong?
