[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.

Question 2
What makes different devices require different kernels?
If I get mt6592 source code from another device can I make it to work with mine
Please help

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] So...ICS issue.

So recently I've been trying to flash the CM9 nightlies and all attempts have led to boot-loops. I was wondering if it was just a bad download so I tried to install AOKP and got the same results...so then I tried the new Paranoid Android rom and still got boot-loops. So is my phone like rejecting 4.0? somebody please help me out with this!

I've had this problem before. What I had to do to fix it was flash another recovery. You can also try fixing permissions in CWM.

Thanks pure! I'm trying the method of fixing permissions first and if that's unsuccessful I'll try another recovery.

I'm still having issues. I've tried the permission fix and different recovery and still nothing.

You tried a new recovery as in you went from:
-CWM to Amon Ra?
OR
-CWM 5.0.0.x to CWM 3.0.0.8?
If you only did option 1, have you tried reflashing CWM in hboot?
If you only did option 2, try option 1 then. If that fails, try going into a saved nandroid, open Rom Manager, and select a different version of CWM. Make sure that you go onto settings and check "Erase Recovery."

I went from CWM to Amon.

So I've still had no luck getting anything to run but my current. I've done all three things mentioned and still absolutely nothing. I cleaned out my SD yesterday and pretty much got rid of a lot of useless stuff, could that have effected anything?

You probably are but i gotta ask, are you wiping everything before flashing? Meaning formating everything in the mounts and storrage menu in cwm except emmc and sd.

Yes I was, this pretty much goes with the whole reason I wanted s-on. I had this theory that if I returned to complete stock and re-rooted my phone that I could flash properly again, and I was correct.

Make sure u back up ur apps on titanium.
1. Wipe user data 2x
2. Wipe cache partition 2x
3. Wipe Dalvick Cache 3x
4. Format boot 2x
5. Format system 2x
6. Format datadata 2x
7. Format data 2x
8. Format cache 2x
9. Flash the Rom.
10. Boot up and enjoy ICS.
This is what I do to make sure it is done. I dont trust manual installation.
Do this every time.

Aha well thanks on the help but I already got everything working again. May I ask why you wipe everything so much? It doesn't really make a difference.

[Q] noob question on reflashing a rom

I flashed CM10 a week or so ago and I want to update to the newest version of cm10. How do I go about doing this? Is it as easy as I think? Download newest version, put it on sdcard, boot into recovery, and install from .zip or do I need to do something else? I'm sure this has been asked before l, sorry. Thanks for our help.

It's recommended to do a full wipe. Than flash the new update zip.

Does a full wipe consist of just booting into recovery and wipe cache partition, delvic cache etc.?

Anyone else know?

Preparation
Before doing the wipe, make sure you take the following precautionary steps:1. Perform a*Titanium backup*to ensure you have the latest versions of your apps saved. Its a good idea to save your internet bookmarks here too.2. Many apps have a backup/restore option so use this to back up your current settings (eg. JKay Deluxe settings, Go Launcher, Fancy Widgets, Simple Calendar etc.). Do this for such apps so that the settings can be easily restored later if required.3. Make a Nandroid backup through CWM Recovery.Be aware of any contacts with personalized ringtones etc. as these will have to be re-assigned after the wipe. There are apps on do download from the Play Store that can save these for you however.
Full Wipe
Boot into recovery
Wipe Data/factory reset
Wipe Cache
Wipe Dalvik-Cache
Wipe Battery Stats
Format /system

CM7 unstability fix..

No I don't have a fix...
So Im using cm7.2 kang and after 3 months of uses its not very stable anymore. As in it will be randomlly laggy and wont do what I tell it to.
Anyway I love CM7.2 so is there a way to make this stable again without a standard wipe and reflash.
Will wiping cache in CWR work? Will formatting system in CWR work?
Sent from my Incredible 2 using xda premium

Formatting the system will wipe the ROM, I would say clear the cache and see if that works.
Sent from my Incredible 2 using xda premium

I would try wiping just the Cache (and Dalvik Cache) from Clockwork. Like EVorhees said, don't wipe the system as you will have to re-flash the Rom.
