CWM - Explanation of wiping bits... - Samsung Galaxy Nexus

Hey guys,
Sort of a noob at this still but getting there but just wanted a bit of an explanation on some of the things in CWM.
The wipe batt stats is pretty self explanatory but I've heard from some very term android users that this does nothing? Thoughts?
The other 2 things were, wiping the "cache" and the "dalvik cache" I know what the word cache means but in this application what are these referring too?
One last thing was, are the mounting options for backup purposes? As in, if you mount the "sd-ext" will it then back it up? Same with the other mounting options??
Thanks in advance guys.

The cache wipes temporary data, while the dalvik cache wipes kernel files which is recommended you do when flashing a kernel.

You're going to want to wipe dalvik and cache (as you always should when Flashing something). Possibly even battery stats if you want to play it safe
Treat kernels just like you do roms I don't want you to be paranoid

Don't wipe data
Do wipe cache
I never wipe battery stats, but I suppose you could.

Exactly...
Just make sure to ONLY wipe cache and dalvik cache. This will ensure that the kernel is flashed correctly with no traces of the previous kernel. Again, like said previously, treat flashing kernels as you do flashing ROMs. It's easy, and if anything goes wrong (rarely ever happens, unless you use a kernel not designed for the EVO, LoL) then it can always be undone by reflashing
Good luck and enjoy! You'll be fine br0
For completeness....(? it's Christmas)
Due to some possible wipe (recovery) issues:
Wipe cache , twice.
Wipe Dalvick , twice.
IIRC
Thanks all for your help. I looked at a couple of different kernels, which one do yall think is the best mainly for the battery anyway?

I'm running SBC-net 4.2.2. And it runs great for me. Good battery and is smooth.
Do you have a link that I can download that kernel?

Try wiping data/system,cache partition, and dalvik 3x and reinstall. If that doesn't work, really download the ROM. Didn't do that for me. But...check his new rom..Urban Fury...

You've tried literally everything? First and foremost you Wiped Data/Cache/Dalvik and then also Formatted System and Data manually before flashing? Formatting system and data is under "Mounts and Storage." I know a lot of people wouldn't get past the boot screen because they didn't do that...

Don't unmount anything.. just format /system under "Mounts and Storage"

I only format /system or /data (if need be) before flashing a rom, never cache or dalvik, which are hash signed. A new rom, a new flash, a new /system, has different hash, which leads to cache and dalvik being rebuilt on first boot after a flash.

Okay let me simplify everything for you and you will not need to pay anyone for assistance. All you have to do is initially erase all data and factory reset, then install the new JellyBean ROM using clockworkmod recovery and after that wipe cache and dalvik cache..you can run fix permissions (i did but not sure if it matters.) If it still is stuck on the boot screen then wipe data again, reinstall JB rom, wipe cache and dalvik cache and wipe anything else you can wipe. After all that mine started working normally. If you are still stuck sent me a PM and I can assist you from Atlanta GA and for free!

Go into ClockworkMod Recovery, then Advanced, then Fix Permissions
I had a very hard time doing it too. The first time I did it I, when I setup the phone, it kept having every app crash, one after another. Managed to get back into CWM and try to restore my ICS and it kept giving me errors. I finally read something about a super wipe, but it didn't say it worked for the GNex, so I just did a cache wipe, and did the data wipe 4 times, and then installed JB one more time, and it finally worked. I never had to fix permissions or anything like that. Perhaps your phone just needs some extra wipes like mine.

(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.

Really. The kernel has nothing to do with the cache partition, so wiping it is literally useless. No need for it, only when switching ROMs, etc, but for kernels, no need.

I believe several kernel devs themselves have said it's completely useless to wipe. Has nothing to do with the kernel at all.

it was something else thar caused the bootloop. dalvik cache and cache involve your apps(system and user).
