I'm all ready to flash a custom rom on my device and came across this: How To Load Custom ROM on Your Android Device (After Using the Revolutionary Method), ( <---- type this link into google apparently im not allowed to post outside links so just type it in to google) however no where in the instructions is he wiping the cache partition or dalvik cache, I've heard from most people if you don't wipe the cache you could end up with a phone eating a bowl of boot loops, or having a paperweight, so is he wrong or is it not important, please explain?

"Wipe data/factory reset" will clear both your cache and dalvik cache. You don't have to do it separately.

hi, I'm going to install new rom on my phone, but before I do that, it asks me to wipe date/fectory reset. I understand that part, but do I need to wipe cache partition too??
what exactly does it do?? is it safer to do it???
Cache Partition
wipe data/factory reset will wipe all user data on the device as well as cache. Doing this will leave your phone in the state it was in when you bought it.
wipe cache partition on the other hand wipes the cache partition of the device to clear all the data accumulated there over use.
I think if you want to start building your phone all over again, like a fresh start you could wipe cache partition too.
Nevertheless, I'd suggest you check-up with on of the more experienced developers and see if they second my opinion.
yep, wipe all of it when installing a new rom..
basic flashing 101...
The collective roms format cache and system themselves before installing everything. Only thing needed for our roms is to wipe data/factory reset.
its never a bad idea, especially for n00bs, to get used to a regime of the following:
format system
factory wipe (data /cache/ dalvik)
wipe batttery stats
then flash..
coming from 3 previous android phones, (2 htc, one sammy), as long as I followed this pattern, I never had issues, and, I am sure I have flashed my phone several hundred,(if not thousands) of times..
I ALWAYS perform the following steps when flashing new roms:
1. Nandroid backup
2. Wipe data/factory reset (x3)
3. Wipe cache partition (x3)
4. Wipe Dalvik cache (x3) (found under the "advanced" menu)
Sometimes i even go through the wipe cycle once after i finish, just for good measure!
...happy flashing!!

Its not necessary to do each three times, once is fine.
What you want to do is the wipe(s), then install your rom and let the rom boot. I have had numerous problems with wiping any data AFTER installing a rom but before a full boot into the rom. So basically, I do the wipe(s), then install the rom (WITHOUT rebooting), reboot and let the rom fully boot and you wont have any problems.
Oh, and my understanding is, if you do a factory reset in CWM, it is not necessary to wipe anything else as a factory reset also does the Davlik cache and cache partition, but not only does it not hurt to wipe all three just in case, a developer can feel free to correct me if Im wrong on this point.

I've flashed multiple roms onto 4 different phones and a tablet in the last 3 days (Captivate, SII, Skyrocket, Note, Xoom), and every guide except the one for the Xoom recommended at least 2 wipes of each (cache partition and dalvik, most in addition to factory). factory wipes are not always necessary, but unless the developer specifies that, it is always safest to just do the wipe. it definitely doesn't hurt.
it takes about an extra 30 seconds, with no risk, and lots of reward.
I dunno, Ive started seeing this come up alot in the last couple of months and Im not sure why. I guess it doesnt hurt to do it all 3 times but it makes no difference whether you do it once or three times.
this is an electronic device, its NOT your butt; one wipe does the job..
if you'll sleep better by doing multiples, knock your sox off, but, absolutely not needed, regardless of what you have read..
Hi,
I was using stock firmware up until yesterday I flashed to v5.2 successfully. Everything is working fine. But I just have a question, I remember that after the flash, and the phone rebooted and I connected to my wifi...the phone automatically started to download and install all the 4 apps that i had personnally installed on the stock firmware all by itself ..
I'm asking because I see that there a v6.0 available and would like to flash that. But before I flash, do I need to do the following wipes?
Wipe data/factory reset
Wipe Cache
Wipe Dalvik Cache
If so, do I need to do this for between EVERY Omega flashes to ensure it goes smoothly? Thanks

You should only have to wipe cache and dalvik then flash the ROM. You'll be fine, I also always format cache and system in the mount and storage part of Cwm recovery BEFORE flashing the ROM, never had an issue.

Is that considered a FULL wipe?

No, full wipe is when you delete all user data as well.

Ok I found the definitions of what a full wipe and no wipe is:
Full Wipe Install means:
- Wipe Data / Factory Reset
- Wipe Cache and Dalvik Cache
- Format System partition
- Install
No Wipe Install means:
- Wipe Cache and Dalvik Cache
- Install
Just a question, in the FULL WIPE listed above, where would I find "Format System Partition?" I don't recall seeing that..which category do I enter to do it?
CWM recovery mounts and storage format system .

Thanks, is there any harm if I do a full wipe EverytimeI upgrade an Omega ROM? I just want to stick to one way of things to minimize any issues.
Hi everybody, I'm a vietnamese. I never used a android phone before.
I see in StreakMod recovery:
+ Wipe Dalvik cache.
+ Wipe Cache partition.
+ Fix permissions.
+ Wipe data/Factory reset (not sure)
I usually do it (in order) whenever i flash a recovery or install a rom. But i don't know:
1. Must I do that?
2. When should I do that, after or before finishing a "factory reset"?
3. After I do a "factory reset", must I do it again?
Sorry about my bad English.

Usually if you are installing a custom ROM it will tell you whether or not you need to do a wipe of the Dalvik cache. Always Factory reset before installing a new ROM unless otherwise noted. Wiping the Cache and/or a factory reset after installing a ROM can usually fix most FC issues and issues adding accounts on a Streak

hi all.
i read many guide about flashing a rom, rom manager, recovery, etc... but i'd like to ask something about it.
wipe cache
i noticed that the "wipe data/factory reset" option also wipes the /cache partition. can i skip "wipe cache" in this case?
if not, should i wipe cache before flash a rom? after? both? i don't know, maybe the cache is involved in the flash process...
kernel/boot animation
is it safe to flash a rom, gapps, a kernel and a boot animation at the same time or should i reboot between some of them?
dalvik cache (with rom manager)
using rom manager with "wipe dalvik cache" checked, i'm not able to see any "dalvik cache wiped" message during the process.
did i miss it? is anyone else wondering this?
thanks very much.
ok guys...
too easy? too specific?
ok, i've just tried myself.

no, no trace of any dalvik message.
so? well, i'm experiencing a bug in my rom never seen before.
i'll try this all again soon to understand if there's really something wrong with my procedure or if it is just a coincidence.
in the meantime, feel free to post your opinions!

ok, i've just figured it out.
the dalvik cache wiping relies on /cache/dowipedalvikcache.sh.
anyway this script has no echo/print_ui lines so, questionable choise, the process is transparent to the user.
Assuming my Galaxy Note II phone has been unlocked successfully, if I do a factory reset to upgrade to note2_JellyBeans_B8.zip:
YOU MUST BE UNLOCKED
Step 1-
Wipe Data Factory Reset!
Step 2-
Wipe davlick cache
Step 3-
install zip and pick your options
Step 4-
Reboot and enjoy!
wouldn't this restore the phone back to stock?? Or is it just the bootloader partition that is left alone when you do a factory reset? Also, the instructions were not too clear when it mentions: "install zip and pick your options". Do I unzip the file and pick something in the install folder? A tad confused here...

You want to wipe system, factory reset, cache and dalvik cache. Factory reset will wipe data like Google account and apps and such.
Then the ROM installs with aroma which loads up a GUI that let's you choose what you want. Can choose apps installed clock location how many widgets you show at the top what kernel you run etc. Literally flash the zip and you'll understand.

Thanks. I am not sure how to "wipe system", but I read how to factory reset and clear dalvik cache. Also not sure how to load the jellybeans ROM(do I mount it.. is it an .iso? etc.)... lots of reading to do. Ty for the input m8.

If youre using TWRP click wipe, then factory reset, swipe to do so, then cache same way, then dalvik.
To flash rom click the install tab, find the rom, make sure you tell it to look at the internal or external at the top and find the rom, then swipe to flash it
sidenote: factory reset clears data, which is what most people do. system wipe actually clears out the partition where the rom is, in other words the phone will not reboot until youve flashed a rom to it

Put the ROM on your phone and go to the install section of your recovery (You must boot into recovery by holding power, home, and volume up while turning on your phone) and flash it from there.

My phone is now unlocked + jailbroken after following instructions from CASUAL. No issues.
When u say put the rom in your phone. U mean my SD card? Per littleguevara's post:
"To flash rom click the install tab, find the rom, make sure you tell it to look at the internal or external at the top and find the rom, then swipe to flash it
sidenote: factory reset clears data, which is what most people do. system wipe actually clears out the partition where the rom is, in other words the phone will not reboot until youve flashed a rom to it" <----- if the phone is wiped then everything is gone so I can't put the jellybeans rom there.
Also from "Originally Posted by nosympathy

Will I be able to wipe cache and dalvik cache WHILE in recovery mode? I just want to be as proactive as possible and avoid being reactive to anything that comes my way that I am not aware of. I believe I already have TWRP (i saw their logo while jailbreaking).. Any input is appreciated m8.
