[Q] Installing acustom kernel - Acer Iconia A500

I interested in flashing a custom kernel but not clear on the steps. Do I need to wipe data/factory reset or just wipe cache before installing? A noob's guide for this is needed and should be added to the sticky thread in the Dev section.thanks for any help.

I just did my first kernel change a couple weeks ago, so I am new at the process myself - all I did ( as advised by members of the xda community) was to
1) boot into cwm and use nandroid to take a full system backup.
2) use cwm to install the custom kernel, just tossed the zip file onto the micro SD, selected install from SD in cwm, took about 10 seconds to install.
3) reboot
4) install set CPU and dance around like a idiot after realizing how sweet my Iconia runs
5) ???
6) Profit
In my experience, make sure to take that full backup and move it off tablet - just in case.
Hope that helps.

you might want to add step 2.5: clear dalvik-cache and cache.

I did not bother with this step - but now I wish I had if it is recommended
What's the logic behind this step? Just random curiosity.

so, do I wipe the dalvik cache and cache before or after flashing kernel? Step 2.5 sounds like after flashing just wanna be sure I do it right. Thanks for help.
Is there an option in CWM to make a backup of the stock kernel before flashing a new one?

[Q] Odin vs. One Click Recovery

To return to stock I was wondering if it was better to use odin or the One Click Recovery.
Do they both do the same thing?
Is one better than the other?

Odin is only true way to go back to stock

I know odin completely wipes everything... if i just wanted to flash a new rom and kernel would that still be the way to go?

You need Recovery to change your Roms. Odin won't do that. If you looking to flash Roms, One Click by noobnl. If you wanna go back to Factory. Odin.
so then in all the threads when they say wipe everything they mean the clockwork recovery stuff. not a system wipe
Simple explination: When they say wipe, they mean inside of clockwork recovery you choose the option to wipe the cache, it would be like formatting a hard drive before you install a new windows os, u want to make sure all the old files and disk errors are gone. Same thing here, the cache is where the data/settings are stored.

awesome guys.. thanks for all your help
Not to be mean but no cache does not wipe your data. It's the equivalent to clearing cache on your browser. When a rom thread calls for a wipe they mean wipe data/factory reset, wipe cache, and go to advanced wipe dalvik cache.
Sent from my SPH-D700 using XDA App
I don't know about the whole format thing... guess you look at it that way. It only clears a part, and there's a few of those. But when you wipe your clearing all your data and setting. Each rom is built different. So in some cases you'll need to wipe to make sure nothing from the previous messes you up. The OP (thread starter) of the rom will say when to wipe. Should always wipe between roms. Cool thing is, you can advance restore your stuff back. ; ) or Titanium Backup. But something will alway catch you off guard or you'll forget. So have multi ways of backup. In clockwork you will see back up (Nand Backup as they call it), this backs everything up, if you mess up you can always go back like it was with restore. Have fun and don't let it piss you off.

With respect a454nova it should be clearer than that. If a rom says to wipe, the clockwork recovery probably should not be used to restore data because the ROM poster is probably putting something in data along with changing the system files. Titanium can be used judiciously to restore data files but only with full knowledge of what the OP has put in the data directory. Best practice is to use listables and download everything new then restore only items that could not be downloaded from the market

You basically need to:
- Download clockworkmod recovery and the ROM
- Copy the ROM to the phone
- Reboot to bootloader
- Flash clockworkmod recovery
- Reboot to recovery
- Make a Nandroid backup
- Wipe cache, data and dalvik cache
- Apply the update
- Reboot

Dalvik is the android Java virtual machine. A cache is made of your current programs to speed things up. Best to clear to let your new ROM build a new version.
Nandroid does a complete system backup. It means if things go wrong, you can restore to a working state. This is done through recovery.

Making a nandroid backup is completely optional. You don't have to, but it does give you a good opportunity to go back in time.
You want to wipe: Factory/Data/Dalvik before flashing a new ROM. Otherwise problems will occur.

[Q] Format system,data, boot, Wipe cache, dalvic!!! Please help clarify

I am going from Autonootered 1.1 to the latest nightly CM7 with Dalgrins Kernel using CWM
Please advise
1. Before installing CM7 what all should I wipe / format
2. After installing CM7 and kernel what all should I wipe/format
Also when I update to a newer nightly later
1. Before installing the newer nightly what all should I wipe / format
2. After installing newer nightly what all should I wipe/format
3. When updating to a newer nightly do I nned to install Dalgrins kernel again
Thanks very much
Anyone ? would appreciate some help
Whenever I try to install a new nightly I have to wipe everything. If I don't all the apps when I try to open them just flash real quick then close. I have titanium backup so its not very hard restoring sense I can just restore all apps + data which makes it a very painless process.
In the Nook General forum user eyeballer has an excellent step-by-step guide for installing CM7. Follow his directions and you will be fine. In general, you do not need to do a complete wipe of everything to install CM7 or to update between versions of CM7.

If you look in my tips thread linked in my signature, I explain what you need to wipe in what situation. But I will explain just a little here.
Ordinarily if you are moving from just one nightly to another nightly of the same rom, just wipe dalvik cache.
If you are moving from one type of rom to another, it is best to do just a factory reset. A factory reset wipes /data, /cache and clears any apps you installed to SD. (And a factory reset automatically wipes dalvik cache since it is located in /data and /cache.)
Never wipe /boot and the new rom automatically wipes /system so you should not have to ordinarily wipe that.
But I have found if you are moving from a CM rom back to stock you need to do a full format with my format zip in my tips thread. It formats /system, /data and /cache completely where using CWM does not.

Wipe is the same as formatting.
Factory reset is listed in CWM as 'factory reset/wipe data'. And it is shown on the main menu. It does what I said earlier, it wipes /data, /cache and clears apps installed to SD.
Wipe dalvik is shown in CWM in the 'advanced' menu.
Those wipes or formats that are shown in CWM under 'mounts and storage' should rarely be used.

If you are going to flash the new JB ROM over the top of stock, you do not have to do anything to the stock ROM first. It will be wiped entirely by the new JB ROM as it is installed. But I would do a factory reset/wipe data first as I said in my earlier post.

No, no, no. Are you not reading my posts? You do not wipe data, cache, and dalvik when you install a new ROM. Just do a 'factory reset/wipe data'. That wipes everything for you. The other wipes are redundant!
And to re-iterate, you have to do NOTHING to stock before flashing the JB ROM. Leave it exactly as is.

Can I pick your brain a little bit?
I had an odd thing happen to me......I rooted and went all delete-happy and deleted a bunch of stuff from system/app without making a nandroid backup...of course stuff stopped working properly, so I downloaded the stock rom rooted and flashed that (with wiping data, cache, and dalvik---even though wiping cache and davlik is unncessary as you explained), but those files I deleted were still missing
The only way I got them back was to do what is listed here (http://forum.xda-developers.com/show....php?t=1904099) and start all over from a non rooted state
Any idea why? If I would have flashed the rooted stock ROM, wouldn't it have wiped my /system too?

You said you downloaded the 'stock rom rooted'. Where did you get that? Also as I explained in my tips thread, sometimes CWM does not wipe things as cleanly as it should. I cannot explain why. In those circumstances I flash my format zip from my tips thread. I suspect that that rom you said you downloaded that you said was rooted was not set up to format the /system.
Also that link you quoted does not work so I can't look at that page.

LOL, well I learned something here. If users start asking questions that do not quite jib with having a Nook Color, I had better ask more questions before I start spouting stuff. I am really glad I added assert statements to my zips to make sure the user is on a Nook Color before the flash will attempt to install.

I am going to make sure I have that assert statement in every zip I make, just to protect users.

Nope, if you continue to use the nightlies, just wipe dalvik cache,
If you come from different rom, just wipe data and cache and dalvik cache.
Once you are on the nightlies you never wipe anything. Don't listen to any nonsense about caches and dalviks just go to recovery, flash nightly, reboot!

You are so wrong. Of course he needs to wipe Dalvik and Cache even if he installs another nightly. Its because the new nighlties bring new apps versions, or new kernel changes. Deleting Dalvik and cache forces the Android to reload the Dalvik cache for all the apps. Also, it saves you from trouble of incompatibility or FC's.

Well you can have your superstitions but there is no rational reason to manually wipe your cache or your dalvik cache when upgrading CM nightlies, and that comes straight from the developers of the ROM who are more knowledgeable than I am. None of the CM devs have EVER suggested it, and when asked, have said that it is not something that should be done. I will take their word over yours.
EDIT: This is the closest I think we will find to a definitive answer: http://review.cyanogenmod.com/#change,4933
So, CM development team does not suggest a wipe of dalvik or cache when upgrading. The nightly installation instructions do not mention wiping dalvik or cache. I personally have flashed several hundred nightlies over the last year and have never wiped cache or dalvik when upgrading. Many many other users have flashed hundreds of nightlies each and have not wiped cache or dalvik and have not had problems. There is no reason to do this action, it is completely pointless. It is like saying "you must have your phone pointing to the east when you boot." Sure maybe it does not hurt anything but we don't really need to keep spreading this superstition.
EDIT: In re-reading this I feel like my posts come across as disrespectful and/or antagonistic. I simply disagree with what was said and I feel I have good reason to. But the OP can read about both points of view and then try for himself and choose what works best for him.
CWM recovery was developed from CM7 devs. So why do you think that they've integrated or made a option to wipe dalvik if that is not needed?
Especially if installing another kernel, wiping Dalvik is a must.
But you are right, the OP can choose himself either he will do that or not.
I don't think that your post is disrespectful and/or antagonistic, you have just expressed your opinion. If we don't discus issues with each other we are not gonna make any progress on learning.

There are lots of options in CWM recovery that are not needed when flashing
Like I said, in the link it is expressed very clearly that the developers of the ROM feel it is "completely pointless" (exact words) to wipe cache and dalvik when updating to newer CM build.
There are times when a user or developer might want to wipe cache or dalvik and so those options do exist. There are other partitions that a user or developer might want to format from time to time for various reasons as well. And the option to do those things is there in CWM recovery. But that does not mean they should be done every time, just because they are there.
In the link I posted, a submission was made to CM code to make it easier for users to wipe dalvik and cache and install a zip all in one command. The submission was rejected because the reviewers agreed that it was "completely pointless."
Why after so much time do you think "Wipe Dalvik Cache" is still obscurely placed in the "Advanced" menu of CWM Recovery? It would be very easy and simple to wipe cache and dalvik automatically when installing a ROM through CWM Recovery or at least put the option on the main page. Do you think that Koush just likes to give users a hard time? Do you think he wants it to be difficult for them to update their ROMs? I don't think so. I think he understand that it is an advanced function that can be useful in some circumstances but is not typically needed in 99% of cases.
The developers also note that the cache is invalidated via hashes automatically. So its basically auto wiped.
The only reason that I wipe is when the nightly contains a new kernel, dalvik should be wiped to eliminate possible problems.

Help with Cyanogensmod 2.3.5 nightly

I have cyanogen mod 7.1.0 RC 1-vision installed on G2 already. Can somebody explain to me how I get to v 2.3.5? I know it has something to do with nightly builds and xboarder56. Im just a little confused on how and what order to flash things. Do I have to install every Nightly update or will the newest one be fine? And exactly what it xboarder56? Is that a modification of Cyanogensmod?
Thanks Sean.....
just install the newest nightly and youll have 2.3.5
xboarder56 is a guy that made a thread on how to install the stock launcher over the ADWlauncher
but you can alternately download a gingerbread launcher from the market and install it
Wipe, and flash the newest nightly just how you flashed RC1

download the latest nightly, put on your SDcard
1) enter recovery (power button -> reboot -> 'recovery')
2) 'backup and restore' -> backup current ROM
3) wipe cache, advanced -> wipe dalvik cache
4) 'Install zip from SDcard' -> Flash nightly.zip
5) reboot
6) fix permissions (ROM manager -> 'fix permissions'
7) reboot again
xboarder56 is a dev on here. he makes several different mods for CM7. The main one that people use is to put the stock GB launcher on CM7. CM7 by default has ADW launcher, but some prefer the stock one. Xboarder56 isn't the only one that has a stock launcher.zip available.
If you want the stock launcher, check the post in my sig. follow the directions carefully if you intend to re-flash nightlies and want to keep your screen placement.
Do I have to download each nightly build? Or can I skip builds from time to time? Are these beta builds? and if so any idea on a final version?
Thanks... Sean...

You can download and install every nightly. But you dont HAVE to. There is a group that only flashes one every few weeks. Either way you will be fine but if you want to be on the cutting edge of new features i would recommend installing it every day. For our phone specifically they come out between 115 am and 130 am. Like said above, wipe cache wipe dalvik install nightly fix permissions reboot with each nightly

Dalvik cache is under advanced. I believe if you're not running Apps2SD you can go without it.

Apps2SD has nothing to do with the Dalvik cache. Wipe it regardless of whether or not you use Apps2SD (which is unneeded unless ur still on a G1).

They are effectively beta builds. They're not official and not necessarily meant for the general flashing community, as they often contain bugs and untested changes.

like I said above, its under advanced -> wipe dalvik cache.
It has nothing to do with Apps2SD. On a related note, there's no need to run Apps2SD unless you have several gigantic games or something filling up internal memory. You should have more than enough internal memory to keep all apps on the phone itself.
When I wipe my Dalvik Cache, CWM says it cannot find the drive/partition for it. Its never caused a problem for me. I assumed it was due to sdcard partitions, which I used to use for Swap and Apps2SD only. Is it an internal memory partition for performance related caching? If so somethings messed up with my partitions.

What exactly is it saying? usually it will throw an error about SD-EXT. disregard the error.
For me when I flash new ROMs I use Superwipe+ to do all my wiping in one step. Its quick and effective.
Check it out:
http://forum.xda-developers.com/showthread.php?t=1044992
Each and every morning, I make it my habit to launch Rom Manager (paid version), and select 'Check for updateds'. After it tells me there's an update available, I approve it and select to download (via wifi) gapps. Once it done downloading it then prompts me to choose wipe data & cashed, backup existing rom, or wipe dalvik cashe. I always select wipe Dalvik cashe, then I approve it to power off.
Bamb! easy sneesy .. My nightly rom gets updated!

I had the same question as the OP. I've been running CM v.7.1 RC1 for a while now and I love it. But I would like to check out the nightlies. Just so I am clear, to go from my current ROM to the latest nightly, I only need to to wipe cache and dalvik cache - and that's it? Somehow I thought the process was more difficult. I thought I'd have to restore my apps with TB and reconfigure all my settings...
And one last quick question. I've never needed to run 'fix permissions.' The sole FC I get is with LauncherPro, but only when I reboot. It doesn't bother me, and it seems like I've read about users who have problems after running the 'fix permissions' in RM. Can anyone elaborate on why that might be?
Thanks so much, guys.

upgrading from an older version of CM7 to a Nightly you don't have to wipe data. Just cache/dalvik and flash the nightly.

Fixing permissions is just a good rule of thumb to follow after flashing a new ROM so all your apps are setup properly. I haven't heard of Fix Permissions breaking anything.
