im trying to recondition my battery. when im wiping my battery stats in clockwork, i encounter a weird problem. right when i confirm to wipe the stats, it just goes back to the menu options. What i mean is that clockwork doesn't tell me that the batttery has been wiped or anything, something that you would see from an Amon-RA recovery. does this mean that it didnt work? please confirm this. thanks
I think it works, just no notification, you just have to trust it
The cake is a lie!
Since I have seen alot of individuals within ROM threads stating things such as, "Your ROM bricked my phone." or "I can't get your new ROM to install." decided to make this guide. Hopefully it will solve this issue and help educate people.
What not flasing correctly can do:
1. Cause your phone not to boot
2. Cause Force closes and issues
3. POSSIBLY Brick your phone (though I have not seen an Eris Brick yet)
We must also remember that:
1. The devs of these ROMs are NOT responsible for any damage to your phone
2. The devs spend alot of time with testing to make sure the ROM works.
3. A ROM will NOT always flash over a previous ROM
OK.. So onto the main topic..
assuming you are rooted and using AMON's Recovery. I suggest AMON's because Clockwork has had recent issues. Big thanks to AMON for this!
How to install a ROM properly:
1. Boot into recovery ( with either reboot to recovery option or powerdown and then holding volume up and power )
2. Goto Backup/Restore and do a NAND Back-Up
3. Do a data/factory wipe ( NOTE: if the dev says you can flash over an old version you dont NEED to do this, but if you don't do this and the ROM is not booting then I suggest you restart this process [minus the back-up] and do a data/factory wipe)
4. Do a Dalvik Wipe... 3 times (ALWAYS ALWAYS ALWAYS do this)
5. Flash ROM
6. Reboot and Wait ( after a Dalvik wipe and flashing ROMs first boot can take 3+ minutes to load... BE PATIENT )
More to Come...
If you could, please explain what a Dalvik flash does. Thanks in adavnce, and thanks for this thread. I've never had any issues flashing, but it's nice to see someone explain the basics....

"Dalvik cache is a program cache area for the program Dalvik. Dalvik is a java based virtual machine that is the bases for running your programs (the ones that have the .apk extension). In order to make access times faster (because there's not JIT (just in time) compiler installed by default), the Dalvik-cache is the result of Dalvik doing a optimization of the running program." - Taken From Android forums
Basically it analyzes the phone before it boots. Then it sees what apps you have and will use and assigns cache to them. This way they will load quickly and properly.
When you flash a new ROM apps can change, or if you do a data/factory reset those apps are gone. SO wiping the Dalvik allows it to rebuild itself for what YOU are using.
This is also good to do after cleaning out or removing many unused apps from the phone. I usually do it once a week AT LEAST.
With the exception of a 2.1 ROM running apps2sd on an ext partition, is there really any point to wipe Dalvik if you have just done a wipe data/factory reset (which also wipes Dalvik cache)? And what exactly is the point of wiping Dalvik three times - why is once not enough? Is there something wrong with Amon Recovery which prevents a full Dalvik wipe unless you do it more than once?
It certainly doesn't hurt to wipe Dalvik after a wipe data/factory reset, but it should be already wiped.
I'm still fairly new, but I've flashed quite a bit. I didn't know to wipe dalvik x3. that's an interesting bit of info. Any reason why? Thanks

I believe the reason is that sometimes even after a wipe people have reported residual data in the cache, I personally don't do it three times but I do a wipe, dalvik, dalvik, wipe.
Its not going to hurt anything and it gives me piece of mind.

cool. Thanks for the good info.
x3? I do once before and once after. Frankly once before has been enough for me... though I suppose being safe has never hurt.
If the dalvik cache still won't clear after 3 times you can piss on your phone. That seems to really help.
in most cases once is enough but like I said, it's not likely to hurt anything to give it a couple of wipes to make sure all the junk data is cleared.
Let me put it this way...
I wont use a public toilet just by seeing it is clean... ill clean it like twice ...
This is why I dalvik 3 times lol

It would be interesting for someone like Amon to comment on the need to wipe data or recovery more than one time. In my opinion, once is enough. I'm 100% confident than wipes #2, #3, and so on are wiping blank space...

I personally and others have experienced residual data... so is three too much... maybe... but its safe... two might be a better choice... this guide was made to make sure you have no issues... therefore I said three times for safety... if you want to just do it once... be my guest

At the risk sounding like an idiot, I must ask this:
You mention wiping the Dalvik once a week. When you do this wipe, do you replace it (flash) something over it? Or can you simply wipe then reboot.

Yep, just wipe and boot. After wiping dalvik, it will redo your app tree or configuration if you will, just clears all the current info and rebuilds it fresh.
Great thread, people still need it I guess

Wondering something here...when i wiped my device, i went thru rom manager and did the wipe device thing to wipe all user data to clear out CM7.0.
after that i installed virtuous to try it out, and i noticed in root explorer in the system>app folder, there were CM apk's in there. does virtuous use CM stuff in their roms?
if not, why would they show up even after a full wipe?
Also, has anyone here ever had issues changing from a non sense rom to a sense and back to non sense in a matter of 2 hours?
well, if they are any of the CM specific apps like:
CMparts or CMstats or CMwallpapers (I think there are a few more, can't remember off the top of my head), then it sounds like a case of a "format" that didn't actually format. you wouldn't be the first person to deal with this problem with rom mgr and CWM recovery.. it is known to be finnicky when it comes to formatting partitions (among other things ).
thankfully, we have a tool now that will give you a true, clean format of /system /data and /cache partitions without having to manually run the commands every time (like I know some of us have been doing).
if you are the kind of guy, like myself, who likes to perform a clean wipe between roms, I'd highly recommend downloading that and using it instead of the rom manager/CWM recovery options.

Can't answer your first question, but on my old Hero, I swapped from an AOSP ROM to a Sense ROM once almost every hour for a day because I couldn't make up my mind. Nothing bad happened to it and my father is using it now with no ill effects.

yes i saw that program pop up when i was tying in the topic for this post! sounds like a great program wish it was posted a couple of days earlier lol. ill try when i get my device back.
wondering tho if these half ass wipes that CWM does caused my problems. i usually wipe when changing a type of rom, even with CM7 (nightly to RC for example). if i flash a nightly, i usually do a wipe every 2 nightlies.
Not sure what you mean by half ass wipes,lol, but I've never trusted the system wipe to do the job. I always do cache and dalvik along with it.

Yeah... as amazing as CWM recovery is, the wipe process can be a bit.... lacking sometimes. If you don't use amazinglarry's superg2wipe script, then I would at least manually wipe through recovery before switching roms - this way you can be at least get most of the artifacts and "ghosts" left over from your last rom.
Sorry for bumping this old thread, I came across it while googling.
I've always used "wipe data/factory reset" in CWM. But that only wipes your /data and /cache partition.
Now, i only recently found out "wipe /system" under "mounts" in CWM. Meaning, I had never wiped my /system partition before, while swapping between 50 roms (be it AOSP or Sense). And I never had any problems. But the best way to fully wipe your system, is to do every partition manually + dalvik and battery stats.
Does it matter to wipe battery stats after flashing a kernel, then doing a bump charge? ...Just to recalibrate it, and get an accurate read.
I've never wiped battery stats since I've had this phone.

I only wipe after major changes. Stuff that would effect performance a lot

No, it doesn't matter to wipe battery stats after flashing kernel. It only matters when the /data/ partition gets wiped, because that's where the battery stats file is stored. That only means whenever you do factory reset, which wipes /data/ of course

So basically when flashing a new ROM, I would do a full wipe, and that too would erase battery stats?
I don't let my phone die fully, charge it completely, or even bump charge it after I do a full wipe. Should I start doing that?
Evo SHIFT
If you're flashing an updated version of the same ROM over the old version, you usually don't have to wipe, and don't have to do anything with battery stats. I think if you do a full wipe and flash a new ROM, try to do it when your battery is full. If not, just charge it to full and wipe battery stats later. Bump charging is debatable, and up to you.
I have a question about wiping battery stats, I managed to soft brick my rom so I reflashed to stock. Should I wipe battery stats again just like installing custom roms or no?

no.
theres actually nothing you need to wipe the battery stats for. its more of a choice if you want to wipe them. it doesnt affect anything when flashing/reverting.
