Used recovery mode and there is no wipe cache partition shown. Any other way to do this?
I can't say it in more professional way, but newer Android does not need it, so they removed that option. I was reading some article which says that if something goes wrong, phone will automatically go to the nearest point, where it has not any issue with booting. If you need to delete something - delete app datas from application manager -> delete cache etc.

Why every time when i install ANY rom to my galaxy s2 after 2, 3 weeks this rom is crashed? It's start crashing with closing apps "application must be stopped". How to fix it? It's the same in every ROM which i install, it makes me crazy right now...
Still no reply?...
Wipe cache and dalvik cache in Recovery.
Sent from my Galaxy S2 GT i9100
I do it always and rom's are still going to be bugged for 7-14 days.
I think I saw you in Paranoid Rom thread mate. Did you come from GB? Just format everything and start again and report back. Format external and usb storage. Wipe data/factory reset. Wipe cache and dalvik and stats once or twice if you wish. Remove crap from init.d or voltage settings just to be sure. Then once you are happy flash rom. Follow instructions - fix permissions etc, etc..See how you go mate.
If it is a specific ROM you are having a problem with maybe post in that ROM's thread to get quicker replies.
EDIT: Also don't restore settings - start from scratch. Don't always restore App+data with Titanium just app only for now.
Before i had problems with every ROM after few days. Yes i come from GB without formatting storage. Thanks for professional response. That's what i did actually:
1. Format external and internal storage.
2. Wipe cache, Wipe data & Wipe dalvik cache.
3. Flash Paranoid 2.22 ROM.
4. Again point 2.
5. Titanium backup just necessary apps.
We will see how long everything will be fine.
PS. what about fix permission? When to do it? And how to remove this "crap" from init.d?
Point 4: Not sure about point 4 - just the dalvik cache and then select fix permissions here. I wouldn't wipe cache and data/factory reset all over again at point 4.
Point 5: Let ROM boot (will take a few minutes)
Point 6: Run an app or two then reboot to make sure..
Point 7: Begin restoring apps or play with governors etc and whatever you like
The "crap" I meant was if you had any additional scripts or tweaks that are in init.d folder during startup. So they don't interfere on first startup. Never tried a kernel cleaning script/cwm flashable file coz there have been some useless ones in the past but give that a try (someone else may be able to comment here).
Remove voltage settings if you were using voltage control app in GB. Reset to default in Extweaks if you were just using this. (Not sure if all this is necessary because I do this prior to formatting or factory resets - someone more knowledgeable can help here).
I'm going to be ROM-ing for the first time (well, other than Safestrapping the Bionic for a day or two) and want to make sure I have the right thought in terms of running and upgrading a ROM over the long term. If I'm moving to AndroWook as my daily driver, I want to make sure I have a good procedure in place for quickly and easily upgrading to the latest version of the ROM.
The following is my understanding of this whole process. Is this procedure correct? My main concern is making sure I am doing everything right to be able to quickly update to the latest version of the ROM when it comes out, not spend a day re-configuring. Is there anything I am missing?
BACKGROUND: Partitions
Main Partitions Involved With Wiping
/system = Where the OS lives, along with the apps that are preinstalled
/data = Where user installed programs & their associated data/settings live. This data/settings is the part that gets deleted when you go Settings -> Applications -> pick an application and click "Clear Data". This is what Titanium Backup backs up for user apps (both the "apps" and "data" backed up live here). Also has SMS, contacts, settings, etc... the "system data" in TiBu
/cache = Cache files that help programs to load quickly. Harmless to wipe, as it will regenerate.
/sdcard = Internal sd card area where you keep files and use file manager. some programs also put files here. Not usually wiped.
external sdcard = Physical external sd card, if applicable. Not usually wiped.
Other partitions
/boot = Kernel and ramdisk. Don't wipe unless you fix it before rebooting.
/recovery = Where the recovery (stock or custom) lives.
/misc = Other settings not normally touched.
BACKGROUND: Types of Wiping
Cache = harmless. Cache regenerates itself over time to speed up phone.
Dalvik = harmless. This is simply another cache, this one having to do with Java.
Factory Reset = wipe /data and /cache. internal and external sdcard is NOT wiped
Wipe system = wipes /system (where the os and its preinstalled apps live)
Format data = wipes /sdcard (the internal sdcard)
Format external sd = wipes external sd card
ASSUMPTIONS & NOTES
You are rooted
You have Titanium Backup (TiBu)
For multi-user environment, modify the instructions to account for the need to backup/restore with TiBu for each user. Backup for each user, flash, then restore for each user.
BACKING UP
1. TiBu: Batch Backup all user apps & data (everything) in current ROM
2. TiBu: Batch verify the backup
3. Make a sketch of how your widgets/homescreen is supposed to look
4. If you are doing a total deep clean that wipes sdcard (generally not), here is where we want to back up anything else (sdcard files, etc)
5. File Manager: Backup apk for both TiBu & TiBu Pro to SD card
Alternate: Do nothing now, and we use market in new ROM later6. Download ROM & put on SD
WIPING & FLASHING
This part subject to change based on ROM maker's recommendations
1. Boot into recovery
2. Wipe and flash:
Option A: Clean flash (typically done, does NOT wipe sdcard):
1. Factory reset
2. Wipe cache
3. Wipe dalvik
4. For a total deep clean (not usually done, DOES wipe sdcard): Wipe system; Format data
5. Flash zip
Option B: Dirty Flash (usually only OK for minor updates):
1. Wipe cache
2. Wipe dalvik
3. Flash zip
4. There is no need to set up the ROM again in this case.
SETTING UP NEW ROM
1. Boot into new ROM
It will take 30-60 minutes to get up to full speed. After that time, it will be full speed after a reboot.
You can tell it to keep backed up to Google (backups up TO Google), but tell it NOT to restore from Google right now (restores FROM Google right now).
2. System > Applications > Unknown Sources
Restore TiBu & TiBu Pro from apk backup
Alternate: get from market
3. TiBu: Batch Restore system data - ONLY THE GREEN ITEMS
Do not restore red items
Do not restore user stuff yet. We are doing system stuff first.
Note that icons will not show correctly yet... nothing to be concerned about.
If the new ROM is vastly different, take care to restore only what is necessary.
4. Reboot
5. TiBu: Batch Restore missing apps with data - ONLY THE WHITE ITEMS
6. Click Market Doctor to verify that everything is hooked back up to the Market OK
7. Fix up homescreen - widgets & wallpaper
One by one, delete empty Widget then add new one.
Also choose the wallpaper you want
8. Check:
Date & time, alarms, ringtone, voicemail number, other settings
Anti-theft is operating properly
9. Market Place > My apps > Update any other apps
10. If over the course of time you find any apps giving problems, use the market to uninstall them and reinstall them to clear out any problems it may have had in restoring from TiBu
I just glanced thru that and this is what I saw quickly.
Option A: clean flash..... I always wipe system as well. This is not a big deal if you don't do it because I format the system in the installer in case people have forgotten.
I also delete cache and dalvik in the installer also in case people forget but I still end up doing them on the wipe page.
The only one really you need to use for a major version update is factory reset. This is just on my rom tho.. I can't speak for how others do it so always best to do the manual wipes also.
Tibu : It is never advised to restore system apps. Even between minor updates in case I have changed a system app.
If there is one that you really need restored then try restoring just the data for that one app and test it properly.
In the installer I do not write all apps to system anyway. There is very little in there that would take more than a few seconds to set back up.
I know this is not a development thread but I must insist we have something like this in this area. I feel it's important to all development for accurate results and debug information.
I see this all the time. People think they are fully wiping when a developer asks for it. I believe that some people still don't understand what a full wipe is because there is no such single option in ClockWorkMod Recovery. Most likely the reason for that is because Koush didn't want too many posts about "I'm stuck on Google logo" or "my phone won't boot". So here is a test you can do yourself: Backup your ROM of course, and then do a full wipe. Then don't install anything and just reboot. If you end up pass the Google logo and onto the boot loop screen, then what you think is a full wipe is incorrect. If you are stuck on the Google logo and nothing is happening however, then congratulations... you know what you're doing 
For the rest of you, here are proper steps to fully wipe without leaving any trace of ROM on your phone:
* wipe data/factory reset
* format /system
* format /boot
Now most people think that the first option is enough. That may often be the case but because the developer can drastically change the contents of the /system folder, things can get messed up if you don't format it. And guess what, that first option will not do it. Wipe data/factory reset only wipes the /data folder which contains your personal settings and all the apps you installed. The ROM is then left blank as if you just flashed it and you can start over. FYI, the format of boot partition simply wipes the boot animation and you can restore it using the advance option in recovery from ROM to another.
I've seen some zip files which do this automatically so that's fine but at least you know what needs to be done to fully wipe.
There you go. I hope this clears some things. Now lets flash some ROMs!

I had to reflash system due to some boot loop. System did reboot and worked fine then. I reflashed gapps too, I'm wondering what was wiped? My system settings seems to all be here..
The only things gone will be root if you had it, maybe a few apps you manually installed to system, and maybe a few settings. Also wipe cache and dalvik because sometimes they don't migrate well. As long as you still have your /data folder you should be good app-wise.
Hey everyone, I am looking for a little clarification on something. I have a Canadian Rogers i717r. I am running the stock Rogers Jellybean ROM I717RUXMD1_I717RRWCMD1_RWC, with root. Recently, I have been noticing some issues with it hanging, and doing other odd things, so I just think it is time for a reinstall. I may have installed a bad app or something along the way, because it does happen from time to time. My main question is this: How do I do a complete system wipe? Now I am talking every old file, so there are no remnants of the old information left. I have done the factory wipe and dalvik wipe, along with the cache wipe, prior to installing a ROM, every time I have done a new ROM install.. It always seems to leave files behind though. Old game files will still be there and such. Is there a way to get rid of it all, so it is a complete clean slate for the install?
Now, I use TWRP, but the idea is generally the same when it comes to this procedure, and I have found these instructions online;
-- The correct procedure for doing a full wipe is below.
Go to clockworkmod recovery.
Volume up, power button, and home button all pressed together for a couple of seconds.
Go to Advanced menu and wipe the dalvik cache and batt stats if present!
Go to mounts and storage and select it.
Go to format / system and select it.
Scroll down to format system and select yes.
Go to format / data and select it
Scroll down to format data and select yes.
Go to format / cache and select it.
Scroll down to format cache and select yes.
Now go back and install the rom from the internal or external sd card.
This is the correct way of doing a full wipe everything is erased and formatted ready for the new rom, no old system files, old kernel remnants etc....
I am curious as to what will have to be done after the install is complete. I am going to lose ALL of the info. I would basically need to redo all the programming on the phone, including the IMEI and all the info for the networks and what the phone needs to recognize what network it is allowed to access and such. Is this what it will boil down to? I will basically need to reprogram the behind the scenes info also, or no?
Thanks in advance!

First, If you're currently using TWRP I'd suggest updating to the latest version, if you haven't already. There's a few of the newer ROMS which specifically require it. On the question of wiping, before you get too carried away it might help you to backup a few things. Within TWRP (ver 2.8.1.0) you have the options to backup EFS (anywhere you please, Internal storage, internal SDcard or MicroSD card) by clicking on the Storage: bar just above the swipe icon. Your IMEI >> located within EFS folder. Also, search the TWRP website for more specific instructions. What you posted is CW instructions. Hope it helps!
