[Q] script for wiping tablet for a real clean install

Hello,
I was wondering if such a thing as described in subject exists.
I am looking for something which wipes everything but the CWM bootloader and the sd card directory.

The option is already there in cwr

Is it cenwesi? I know the wiping section, but for instance there's no option to format or resize the /recovery partition for example.

if you format the recovery you would lose CWM. A data wipe should be suffient, if not plug it into a computer and delete everything on the "sdcard"

thanks, I now have 13 Gb available, is the rest taken by the recovery partition? is resizing an option?
(pls forgive me for being ignorant

I think the devs would have to put a wipe script in their ROMs so the user doesn't have to do it manually. At least that's what the devs at my smartphone's forum (Vibrant) do. Albeit, sometimes it is best to do some manual cleaning, and TWICE at it (the system isn't infallible).

create ext4 for use with a2sd

hi,
i'm usin ra passion 2.2.1 and wan't to use a2sd from ics 4.0.3 evervolv. how can i create a part ext4?

Google:
"a2sd partition sd card".
Enjoy.

Try 4EXT recovery www.4ext.net
I think its the easiest way to create partition.
Or else you can do it in pc via partition managers(i use minitool partition wizard)
You can google it and also can search in youtube for video tutorials.

thanks for your help, i've done it in recovery.
one question is left:
what happen if i format the partioned sd-card under windows and do a full wipe in preparation for installing a new rom. i've read sd-ext even survive a full wipe? what does that mean? stays the partition untouched when i format the sd-card with windows? and what about the apps in the partition? are they still there even after a full wipe and can i use them after flashing a new rom out of the box?

Glad u succeeded in partitioning
Now if you format the fat32 partition in windows using those partition tools doesnt affect ur ext. Ext stays untouched but all the data on fat32 will be wiped(so backup first to pc)
If u want to merge there is an option called merge for that.
There is an free windows software called sdformatter, that formats the entire sdcard(fat32+ext)
Hope i helped a bit :thumbup:

ok. i wan't to format it with the windows internal function via right click. is it the same and the ext4 stays untouched?

Full wipe in recovery wipes SD-EXT too.

i do beleive that it should be untouched, cos normally windows cannot see the ext partition and hence only fat32 will be formatted

ok. when ext4 stay untouched and i flash a new rom the apps are still in the launcher after flashing?

when i flash a new rom i use the format.zip form the xda user temasek which wipes system, boot, data and cache. so is sd-ext untouched when i use this file?

You insist on not listening and/or not understanding.
When you select "wipe data/factory reset" in custom recovery, EXT partition IS WIPED COMPLETELY. It doesn't stay.
I believe the same happens when using temasek's script, never bothered using it, so I can't say with 100% certainty.
If you don't wipe your phone and install a new ROM - be prepared for crashes of anything to everything, unless you install a ROM which is 100% compatible with what you have already - the next generation of the same ROM, usually.
If you're using A2SD and don't wipe EXT partition - you'll have crashes as soon as you boot, since system apps' data will be there (and wrong).
To keep your apps and their data, use one of the backup apps available in the Market, like Titanium Backup.

as Jack_R1 explained its always better to wipe everything(system,cache,dalvik n sdext) to be on safer side to avoid crashes n FCs.

Temasek's Extreme Wipe does Data/System/Boot partitions but don't remember seeing ext in the list
However, as alluded too, I would format all outside phone with sdformatter or I think gparted, although never used that one
I thought I read a long time ago Windows formatter not recommended and do a full wipe not partial with whatever you use
Back up sdcard first
also, I believe you can use the Alignment Cool zip to get ext 4 from 3 on Amon and not lose anything--still backup
you do know MeDroid uses Ia2sd and different from a2sd on implementation

You don't need to wipe the regular FAT partition on SD card between flashes, because there's nothing there that loads automatically. And "wipe data/factory reset" option in recovery also wipes /sdcard/.android_secure.

hey guys, thanks for your answers i will keep them in mind.
edit:
one more question:
if i uses temaseks script and the sd-ext is untouched and i flash a newer version of my rom, are the apps then still there after flashing and booting the updated system? or is there another step i've to do?

No, the apps aren't there anymore - or to be correct, the apps are there, their data is gone (because the app data doesn't reside on EXT partition, unless you use specific mounting methods).
When you flash an updated version of your ROM, just don't wipe anything at all unless the instructions specifically mention having to wipe before installing that version. That means - don't execute temasek's script at all.

"Full" Wipe

It seem CWM full wipe isnt enough, it left the data in sdcard and root. How to "clean' up totally and safely. If possible I dont want to mess with the repartitioning maybe some full format would be nice. Any guide from experienced user...thanks

If you are on safe kernel you can wipe/format sd card by following these two methods :-
Go to Settings>Storage>Format SD Card (Internal)
oR
Reboot in CWM Recovery
Go To Mount & Storage
Format SD Card (Internal)
Hope it helps
Cheers!!!

this will full wipe
*2767*3855#
recommended only if you are on GB OR ICS with safe kernel.
Root will not still remove, you need to reflash Stock ROM(recommended GB) with PC odin to unroot.

on cwm and safe kernel.
Take out out external sd card
wipe factory, cache and dalvik
Then in mounts format everything except efs. Phone wont boot but will boot recovery and download mode.
Put external back in and install zip, or pc odin your prefered way. With regular pitfile if switching GB or ICS.
Cleanest way possible to my knowledge.
When not switching and on safe kernel dr ketans way is the way.

Go to Settings>Storage>Format SD Card (Internal)
This one I supposed /mnt/sdcard only right?

To Brick or NOT to brick

I have searched many posts & not found substantial information or answers...........so
2. I have tried various ROM's....CM9, CM10, Liquid RC3, asylum & slim 2.7 (current) amongst others including sock Gb &ICS
3. all this flashing has eaten up my INTERNAL storage what I understand as being emmc (or part of) partitions for rom, bootloaders,etc ............. SO
Q, if I format emmc in mounts & storage in CWM recovery 6.0.x.x will I brick my phone? I just wish to clean the emmc & breath a bit of life back into my note without flashing back to GB, I have read it can be done via PC on USB connection method & I will use this facility to copy files that need keeping before formatting.
Many thanks in advance

Is ur partition broken???

Flashing a new ROM from a safe kernel and doing a wipe data/factory reset should take care of everything but the sdcard partition, and that you can clean yourself with a file manager.

actually what he wants to ask is
what will
format /emmc do in cwm?

If on a safe KERNEL, then formatting is safe from bricking. Be careful though, some cwm recovieries have emmc as EXTERNAL SDcard.

so just remove the sd card before u try it

[Q] Format emmc in cwm

So the title says it all. I'm looking to clean house a bit and just delete everything on the internal memory and install something from the sdcard. I normally just do a factory reset and wipe caches but there's remnants of passed ROM installations and general clutter that still linger. I saw the options to format emmc but chickened out before doing it. Will this do as I describe or is it something else entirely?
Thanks in advance!

Just did that recently on the Nook and have done that multiple times on other tablets. But I normally have an externalSD hooked up (with all the files I need).
Once I formatted the whole nine yards and was in a panic until I realized I could take out the microSD over to the PC to get the files back on, plugged it back and
reboot the recovery to get back.

That's pretty much what I was hoping would happen. I'd just have my new ROM and gapps on the sdcard and flash from that in recovery after formatting everything on internal memory.
Groovy, thanks.

If you are installing a new ROM on emmc, you do not need to format /system with CWM, the zip does that for you. The only thing you want to do in CWM is wipe data/factory reset. That formats /data, /cache and clears the dalvik cache for you. It will leave your internal media files intact. Be very careful with formatting anything else. It can brick your device.
