Cm7 rc4

I'm currently running cm7 rc3. Do I need to wipe cache and data if I'm upgrading to cm7 rc4?

I did a flash over, didn't wipe anything. No problems as of yet.

Its usually a good idea to at least wipe cache and dalvik. Shouldn't have to worry about data unless you are having problems.

Wipe cache and advanced>dalvik. Then apply the CM.zip, then GApps,zip if you use those, and then any custom kernel that you use.
Doing a backup beforehand is always recommended

Same thing here, no problems yet.

Rule of thumb is to just wipe the cache/dalvik if your updating to the same ROM, just a new update. It's really only when your cross-flashing a different ROM where you need to do a wipe data/factory reset.

Return after MIUI

I just sifted through the forum and couldnt find anything so is there a special thing you have to do if you want to return to Sense after CM 7 and MIUI? Or can you just flash a Sense rom?
I remember on the Fascinate we had to ODIN a stock ROM after because of MTD BLM.

No you can just flash. Well you should clear data/cache.
I normally wipe data factory
wipe cache
format system
clear davlik
clear battery
then flash.
Might be to much but thats normally what I do and Ive never had any problems.

I would definitely wipe all those, especially from an AOSP Rom to a Sense Rom

FWIW, I do the same, except I don't bother to wipe battery stats.

Make sure you return to a stock kernel as well (if you changed it). From what I have heard, sense and AOSP kernels are not compatible with each other.

This is TRUE!

Better yet... Couldn't U just make a backup of the sense then just restore it

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.

Did I Flash M5 right?

I flashed AOKP milestone 5, I was coming from M4. I backed up SMS, pics, music and synced to Google for contacts in anticipation that when I wipe/reset I'd lose everything...
Flashed m5 and gapps after wiping and when I rebooted Android started to upgrade them it said something about apps and went configuring apps 1/138 and so on until it was done.
I was booted back into exactly what I had before same settings, apps, music. I went to about screen and I'm on M5 and 4.04
Did something go wrong ? Should I of had to get all my stuff back? Did I do a dirty flash somehow?
Thanks for any help.

Sounds like you didn't wipe it properly if it is working good no need to now but if you have problems then you should wipe and reflash.

Did you wipe all 3 areas? And how many times did you wipe?

I went into recovery and did wipe/data reset

Should I have done something else? Why did it install fine but I had everything still.
Like music pics contacts sms

Any extra input on this? Shall I reflash, I've been going for a few hours now and haven't noticed any problems but I want to be on the safe side

Check the Android revolution thread for the super wipe zip. Flash that then re flash m5.

You are good. It was rebuilding dalvik cache from you wipe before the installation.

So any reason that when I wiped, it well, didn't wipe? I only did data/factory reset in the recovery menu.
Sent from my Galaxy Nexus using XDA

You didn't wipe cache and Dalvik cache.

Factory/data wipe formats cache & data.

I wiped, cache, dalvik cache and data/factory reset then flashed AOKP M5 and Gapps again. When i got rebooted, its the same thing.. all my music is there, pics,sms, contacts, apps.
Why wont the phone let me wipe and install a rom fresh?
Is it because im already coming for aokp m4?
It is something to do with Clockwork mod?
Please help.

Try that super wipe lite zip mention earlier or go into the mounts section and format data, cache and system. Then wipe dalvik. Flash rom & gapps again.

i had this problem before when doing factory reset from cwm. i just use fastboot to flash stock 4.0.4 then use cwm to flash aokp.

1) wipe data/factory reset
2) wipe /system (if you don't wipe this partition it leaves settings and files from the previous rom that could prove problematic)
3) wipe dalvik
4) flash rom
5) flash gapps
if installing a kernel after wards
6) wipe dalvik (again)
7) flash kernel

The music and pics should matter unless your wiping the sd card in recovery the SMS should have been gone after a wipe though

Yeah the SMS is still there.. idk what to do its not like the phone doesn't work or anything but its weird that I can't wipe and start clean I'll prolly have to unroot/ lock the boot loader and start all over. If anyone else has any input, please share

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.
