Hi, modiffying software and testing different mod's i a plaeure, but this leaves some files here and there and in the future this may become a problem.
In the root folder of the phone I see folders like: acct, cache, config, d, data, dev, vendor...and also some files: default.prop, init, init.goldfish.rc... Are these files and folders permament or there is way to format everything and make clear install after that?
For example I had to add label to my ext partition to be able to use app2sd on CM7, so I changed something in "vendor" folder(following instructions offcourse). But now If I want to cange the rom and use another one I wont need tis label or it can even cause some problems.
What exactly dissapear when whiping everything from recovery and installing new rom and what stays?
Thanks.
Hey.
Boot into recovery. Do a full wipe, and you can format yr SD card.
That'll completely wipe everything.

If you do a full wipe and flash a new rom only the sd is not affected. Some roms might not format the system partition but you can do that yourself, even tho i don't think it really matters.
If you wipe data/factory rest, cache and dalvik cache before flashing everything should be gone.

I need some HELP!i have htc desire rootes and s-off!(i had the official 2.3fist but still manage to make it).

4)reboot system
I used this rom and loved it but afterwhile when i press htc browser it "tells"me storagy full.
what i should do?????
How big is your EXT partition? And check if your EXT partition is being used with Quick System Info or Titanium Backup.

the firt is what i get when i try to open htc browser
the second is the what i see in quick system info
As far as i have understan AD2SDX is a program that moves cache-dalvik to sd-ex and helps mobile see sd-ex as ram.Furthermore most of .apk will be install to sd-ex after flashing AD2DSX.However cache is still on mobile's ex so that is why on xda site says:"boot into recovery, clear the Cache (but NOT the Dalvik cache) and then reboot. Then try installing the Cache Cleaner app."
Unfortunatelly i did that and still nothing.
The bad things is sometimes not only htc browser won't start and shows that picture that upload but there are some other programs that is forced to cloce such as market and facebook.(Even though all the above after wipe cache(using app)i am able to download opera mobile(25mb).Opera could browse and htc browser still gave me full storage message.)
My thought are that something went wrong at installation or it is the HBOOT.But i really don't know-understant so much thats why i need help.(it's about 1-2months i learned what root and s-off is!)
The solution is simple. Do not flash the ad2sdx. If you have titanium backup, on the first page, you can check your ext storage and see what I mean.

Your titanium backup info shows that you are using stock hboot (250MB system, 150MB data, 40MB cache). APP2SDX requires a CM7r2 hboot. Change hboot with Alpharev and try reflashing the rom again and see if you have this problem occurring again.
Sent from my HTC Original Desire with Android 4.0.4 ICS using Tapatalk
I was running this ROM until a few days ago. I have a stock hboot like you but I had plenty of space using the stock a2sd that comes with the ROM, no need to install run an extra script (even if it did work with stock hboot). From memory, I had 500 or 600MB remaining for apps on my 1GB ext4 partition.
Looking at your TB screen, your ext4/a2sd partition is quite small, showing a 154MB partition (not 1.2GB) with just 978kb free - this would explain the low memory errors that you are getting. It would be worth taking another look at your partition in GParted.

You don't seem to understand. He has this problem (low a2sd) because of the x script. There is no need to change the partition. If you really want to use the xscript, change the hboot to cm7r2. But I would strongly advise you not to use it. Switch your hboot to cm7r2 and use a2sd. You will get more speed and enough app space.

I just started everything from the beggining.
1)dowload and rename PB99IMG_cm7r2 to PB99IMG
2)make the partision from the begginig(just in case)
3)i put the PB99IMG the Runnymede AIO V6.0.4.3 Special Edition and my old file clockworkmod.Clockworkmod just in case.
4)update the phone with PB99IMG(did not reboot)
5)went into recovery flashed the Runnymede AIO V6.0.4.3 Special Edition
6)reboot the system
The only strange thing is between 5 and 6 i got this message:
"Aroma installer finished…
E:Error in /sdcard/Runnymede_AIO_V6.0.4.3_Special.Edition.zip

Installation adorted."
what does it mean???Shouldn't i get:instalation finished or something like that??
The second thing i was confused is that i get opera mobile app cache cleaner and titanium backup without downloading them if i remember well the does not come with rom!!right??
P.S:1)i didn't put the AD2SDX zip file in sd-fat32 but i did get the option of it at the preferations in the rom installation(i hadn't this option before)
2)i will use for some days the rom and tell you what i get!

Can you Post the aroma log here? I suspect it's because your have not fully wipe the partitions, hence the error. And the 2 apps it's possible that it came from before you reflashed the ROM.
The reason you have the A2SDX option now is because it is supposed to be used only with CM7r2 hboot and hence because you are using it, it appears as an option.

I didn't understant what do you mean by this :"Can you Post the aroma log here?"
I make the partision from the beggining so i believe that sd-fat32 an sd-ex4 was completely empty,so there were no app in sd.
Let's talk about the phone now i did a full wipe(1)wipe data/factory reset
2)wipe cache partision(wipe cache)
3)advanced->wipe dalvik cache
So if i am not wrong no rom and no app should be neither to sd nor to phone.Right?

1) Ignore the log part, I forgot that that's optional. Basically when you install a ROM with aroma, at the end there is an option to save log so that we can see what had gone wrong if problems cropped up like yours.
2) No. What you do just ensured that your sd-ext and data partition is empty. As such you will not have any apps, but your ROM (or most of it) is still intact as the system partition is not wiped. However, Sense roms from 3.0 and above will store some files on the sd-ext partition as there isn't enough space, so when you wipe the sd-ext (factory reset), you are left with an incomplete ROM.
Edit: To write system partition go to Advanced> format system

So you suggest to do all from the beggining adding one step before reboot system: Advanced->format system????
As i saw at recovery->advance->(i have these options: )
-reboot recovery
-wipe dalvik cache
-wipe battery stats
-report error
-key test
-show log
-partision SD card
-Fix permissions
By the way options at recovery are
-reboot system now
-apply update from sdcard
-wipe data/factory reset
-wipe cache partision
-install zip from sdcard
-backup and restore
-mounts and storage
-advanced
-power off
what should i choose??

The option should be in mounts and storage if I'm not mistaken. Sorry, all the recoveries place it at different places and I get mixed up with the locations.
So all you do is (presuming you've changed to CM7r2 and your ext partition is created)
1) Full Wipe (Factory Reset, Wipe cache, Dalvik, Format System)
2) Flash ROM
3) Flash mods (optional)
4) reboot system

Mods just means modifications to the original Rom. If you check the threads normally, other than the original rom zips, there are normally the 'addons' such as framework mods, a2sd scripts etc. which you add after flashing the Rom.

I've been working on this port for personal use, but I figured others may find this useful.
What is it?
It's a script flashed through recovery, same as when you flash a ROM, that wipes for you in one simple step!
What does it do? (Wipe)
Depending on which version you choose, it calls on mke2fs and e2fsk to format /cache /data /system, then check the partition afterwards.
It will wipe /cache for the cache only, or system, cache and data for the full wipe. It does not do the external SD card, but it WILL FORMAT INTERNAL SD!
What does it do?(Nullify)
Same as the wipe, however this first calls on DD to zero out the partition, leaving NO DATA behind. Its a full overwrite of all data in the partition, with no way to salvage after running. The chances of anyone being able to recover any data after this is run is pretty slim outside of extreme power users and like..the CIA or something. Even then the data would be so corrupted I doubt anything usable could be rebuilt. Best used when bugs come up regardless of wiping multiple times, or prepping the tab for sale, no personal data can be retrieved from the internal SD.
How do I use it?
This is assuming you run a custom recovery!
System Wipe:
Reboot into recovery (this has been tested on my personal device with CWM and TWRP).
Make a full backup.
Install from SD, pick the system wipe zip.
Install the zip.
Wait a bit, it should take a minute for full wipe.
You can either restore a backup or flash a new ROM zip.
OPTIONAL: Fix permissions
Reboot system
NOTE even on a restore first boot will take longer then normal.
Cache Wipe:
Reboot into recovery.
Make a full backup, just in case.
Install from SD, pick Cache Wipe zip.
It'll take a second.
OPTIONAL: Fix permissions
Reboot system
NOTE boot will take a little longer then normal.
Nullifier:
Make sure you have at LEAST 50% battery or are plugged in.
Copy all information and files you want to save from Internal SD to PC or external SD card (the slot one).
Reboot into recovery.
Make a nandroid backup.
Install zip from SD, pick the nullifier zip you want to run.
Cache nullify takes about 9 minutes, full system takes about 35-40.
Check if you can mount /system /data and /cache, if you can, proceed, if not, reboot recovery (recovery not system!)
Install from zip, pick your ROM zip, or restore a nandroid.
Reboot system, and do whatever the DEV suggests.
NOTE Boot will take longer then usual.
What's this ported from?
This is based on work by Volk's Nullifier script for the G2x, and based directly on the Hellfire Nullifier. It's no longer really even close, but the concept and work is still based on their work.
What does each version do?
Cache Wipe: Formats /cache and deletes /data/dalvik-cache.
System Wipe: Formats /cache /system and /data. Recovery mounts INTERNAL SD to /data/media, so THIS DELETES INTERNAL SD!
Please backup your INTERNAL SD before running this or you will lose everything on it!
Cache Nullify: Nullifies /cache and deletes Dalvik-cache.
System Nullify: Nullifies /cache /data /system. THIS DELETES INTERNAL SD!
Cache Wipe\Nullify is meant for cleaning up when things get buggy.
System Wipe is meant to format everything for a new rom install or nandroid backup restore. The recovery will remove directories around /media, not format, this will format /data completely in preparation for new data.
System Nullify is meant to destroy all data in /system /cache /data, including your internal SD, by zeroing out the partitions. In other words, writes 0s from start to end.
Who should we thank?
Volk, who created the initial concept and script Nullifier, which this is based roughly on.
x0hell0x who ported it to the Hellfire Kindle Series, which this is based directly on.
da-pharoah, who helped me through the process and dealing with different device IDs in different recoveries. If it weren't for him I'd have given up and made seperate zips for each recovery.
What's coming up?
Right now I think this is complete! I'm unsure of how it handles CWM, so I may need to create CWM versions.
Things to note! READ THIS!
This is intended to run on the Acer Iconia Tab A100 ONLY! I have not set this up to run on any other device, and doing so may result in a brick! This wipes partitions, and could wipe boot, recovery, or any number of other partitions if run on a different device!
This was created and tested on my personal device using TWRP recovery! Using any other recovery may or may not prevent the script from running correctly! System wipe\nullify erases internal SD please backup data and ensure your ROMs and Nandroids are stored on EXTERNAL SD CARD!
The wipes are meant for every flash, the nullifiers are NOT meant for every flash! They are meant for changes from one ROM to another rom, or every few flashes, say 10. Otherwise use manual wipes or my wipe scripts!
Porting:
I'll consider porting to other devices if I have time, please PM me if interested.
I am not responsible for any damage that may occur from use of this script! If you choose to use this, that is your choice. As with anything else, flashing can cause problems including data loss, hair loss, bricking, brick laying, and magical fairies cracking your screen.
Changelog:
5.25.12 v0.1
Initial attempt at porting over, full of fail.
5.26.12 V1.0
Wipe Cache only version completed and successfully run on my device in CWM and TWRP.
5.27.12 V1.0a
Minor changes to the script for cache only version.
5.28.12 V1.1
More changes, changed handling of device ID from recovery to handle both types of recovery reporting (thanks da-pharoah)
Adjusted the status bar indicator to better reflect where in the operation the script is (thanks da-pharoah)
5.30.12 V1.1a
Created post, minor clean up of spelling errors.
5.30.12 V1.3
System Wipe finished after some major changes to command arguments. Cache wipe getting updated as well to 1.3 with a fix to rm argument.
6.1.12 V1.4
Cleaned up an error with the cache being formatted and throwing errors. Updated and cleaned up Cache Nullifier, all scripts updated to 1.4.
6.1.12 V1.5a
I made a mistake and updated the wrong script versions, resulting in nothing being formatted due to the system not unmounting before carrying on with the script. My apologies, I hadn't noticed the issue until I attempted to use it today for a rom install. For now, use only 1.5a versions, updating them all now with the fix. Slight changes to output to help see what it's saying. Working on getting the status bar timing correct.
6.3.12 V1.5a Final
Rechecked each script, and should ALL now be FULLY working in TWRP. CWM may or may not handle the script correctly, if you run into issues like it not working, send me a PM or Email with /cache/recovery/last_log and if there dmesg. System Nullifier added finally!
Please bear with me, I'm finishing my High School course and only have limited time on any given day, and it mostly goes to schoolwork, I will update when I can, and I really hope to have the full wipe completed within a few days. Nullifier may take longer as I'm not sure why DD hangs.
Downloads: These are on my drop box for now, it's small so it shouldn't cause issues.

Right now all it does is format, or wipe, with mke2fs to whatever FS that partition uses, EXT4 or EXT3. Its not much different from using CWM wipe/format commands, just does it all for you. Once I figure out why DD hangs, it will then Nullify the partitions, complete and utter destruction of data by overwriting the partitions with 0s, leaving no traces behind at all. I'm currently hammering out the full system wipe script, which will do /cache /system /data and /data/dalvik-cache, the /cache/dalvik is done when /cache is formatted. The problem I ran into is for some strange reason, internal SD is mounted to /data/media in recovery, meaning formatting /data directly will erase the internal SD card as well. The recovery gets around this by deleting directories around it, but never formats it, which IMO can lead to issues and bugs down the line. I have only 1 method of dealing with this, and that's moving /data/media to the external SD card (SDC), formatting (or nullifying) then moving it back. As this can mean moving up to 8 GB, its not a liable method as it will take a LONG time to move it there and back.
I'm hoping to have the first full system wipe available tonight, however it WILL erase the internal SD, this is only to be used if you don't care what's there, or are having alot of bugs, and copy your stuff off before running. I can't test it since the wife is using the tab now, and I'm not gonna put it online without testing it first.
TL;DNR: It just erases it.
Updates
1.4 versions are up.
Now includes Cache only Nullifier! This is the wiping that I think joeyjojojjjjjj was looking for. Unrecoverable data destruction. Currently DDs /cache, then formats and checks, then deletes dalvik-cache. Overwrites the partition with 0s from beginning to end, leaving nothing but ZERO behind, hence blackhole nullifier.
Hoping to finish up System Nullifier tonight some time.
1.5a Final is done
Scripts are now up to 1.5a Final. The zips are still labeled as 1.5a but they are all updated. Added system nullifier! Please use caution with the wipes and nullifiers, and ensure internal SD is backed up and your nandroids and roms are stored on external SD card before using!
Tested working on TWRP Recovery, YMMV on CWM recoveries.

Wipes with Crossix Memory Swap?
I am using the Crossix memory swap.
If I use the system wipe script, will it erase the data on my *actual* internal sd (i.e the 5gb partition that I largely don't use). Or will it erase the data on my *tricked* internal (my 32gb microsd card)?
Thanks, I can't wait to try this stuff out!

Internal SD only. It will never touch your external SD card. And the reason is....
The crossix mount swap is only active when android runs from /system. This is run from recovery, so any system mods don't affect anything running in recovery.
So you're safe, only the included internal SD is wiped, regardless of crossix's mount swap.

Oh OK I didn't see the edits.
Anything using nvflash or apx mode needs the sbk, no way around it. It may yet be cracked like the a500s, but so far no.

From my understanding formatting the /system partition through CWM will remove the android OS completely from your device and you would have to flash a new one to replace it. Found the following information on the below website:
http://www.addictivetips.com/mobile...plained-boot-system-recovery-data-cache-misc/
/system
This partition basically contains the entire operating system, other than the kernel and the ramdisk. This includes the Android user interface as well as all the system applications that come pre-installed on the device. Wiping this partition will remove Android from the device without rendering it unbootable, and you will still be able to put the phone into recovery or bootloader mode to install a new ROM.
My question is, if I format the /system partition, does it remove all my currently saved pictures and videos on my internal memory? When I install a new ROM I typically wipe data /factory reset, then perform TDJs super wipe before installing the new ROM.
However, the instructions for installing the newest CM10 ROM also says to wipe /system partition. I know this will remove the OS, but will this also remove my pics and videos or should I back them up first before performing this step? Thanks.

Now i could be wrong as i am no Dev by any means but i do not think it will wipe your emmc as well. Reason i think it will be fine if you wipe /system is if you go in with root explorer and go to your /system folder your emmc is not located there so therefore if you were to wipe your /system patition it sould leave the emmc partition in tact.
But as always i would backup your emmc to your pc and give it a try. Hope this helps :good:

I was thinking the same thing as well but just had to ask because I have never processed the format /system action before. I am currently running a TW ROM ATM and looking through ES File Explorer my sdcard (which is the same as emmc on AOSP ROMs) isn't located located in the /system folder either.
Thanks for your reply, I tried to give you a thanks but I have reached my limit today

I'm no Dev either, but your right. Formatting system will not touch your emmc or sd cards. If you format system when flashing a new nightly (which I do every 3rd flash), you won't lose any user data at all. Only ROM and system apps, this is why you need to reflash Gapps as well if you format system.
When you use TDJ's wipe script, it formats everything (including system) except emmc and external sd cards.

Thanks so much, I run TDJ's wipe script with each install of a new ROM and completely didn't realize that is also wipes the /system partition. I just re-read his Superwipe thread and right in the OP it says
"This exceeds anything that CWM is capable of from the menu options. This will format and erase EVERYTHING on your /system, /data, /cache partions with EXT4 file system. It WILL NOT wipe SD CARD or EMMC... After it is complete with format and e****, it will align all disks partitions properly."
I was up extra early this morning, forgive me, I need to learn how to read better as well :laugh:
Thanks again.
Remember guys, wiping doesn't wipe everything. However, not wiping everything can bring its own issues.
Sorry for bumping up an old thread but it was very relevant to this topic. If I wipe the system before flashing a new ROM will my apps remain intact with their data? I know system apps will be gone but they will come back anyway so it doesn't matter.

No, I flash all the time and always format system, you will not lose your internal or SD memory

Yes, they will stay intact with a /system wipe. However, with a factory reset or /data wipe, your apps will be gone.

Sorry to bump old thread. I just deleted system, data, cache etc everything. Now when i attempt to
Reboot it warns that no OS installed. I m using TWRP. is it safe to power off the device? Will i be able to get back to recovery to flash a new rom afterwards, as i dont have one ready now??
Btw i hav nexus 7 , but didnt find this discussion there so i am posting here.
Thanks in advance for help....
I accidentally formatted system on my HTC desire HD. but i'm unable to install rom in it. If anyone can help me make it working(instruct how to install ROM in it) i'd be grateful.

Hello all,
Sorry for this semi-noob question. I have had many android phones and rooted all of them but this is my first Nexus device. I've unlocked my bootloader and have TWRP installed and I'm ready to install a ROM. Unfortunately I am unsure of how I can do a full wipe without wiping my internal storage too.
On every other phone I have had, I would go to advanced wipe and then wipe system, data, cache and dalvik cache but I just did that and it wiped my internal storage :/
I had to flash the stock system image through ADB because ADB sideload wasn't working. Now I'm afraid to wipe system again before trying again because I feel like it will wipe my internal storage again. How can I wipe system properly before installing a new ROM?
Thanks!
Now the interesting question here is: What is internal storage?
You seem to think it is the entire emmc, including your system, cache and data partitions but that is not how that term is used.
As far as I have been able to figure this out "Internal Storage" in Android refers to the entire /data partition which in itself again is divided into a user accessible part where your photos, videos, files are stored ( /data/media and mounted as /sdcard/0 ) and the rest of the /data partition which is used for apps you install and their data. That part is not accessible to the user unless you have root.
Now, for 99% of all wipe operations all you need to do when installing a new rom is to wipe the data partition of all user installed apps and their data, dalvik and cache - also called a 'clean install'.
Any rom installer worth a damn will format /system before installing a new rom, so wiping /system is redundant.
TWRP made this very easy: Enter the Wipe menu and swipe the button. Default is to wipe /data (without wiping /data/media), cache and Dalvik. Flash the rom - done.

"Internal Storage" as I used the term refers to just the user accessible part of the data partition where (as you said) photos, files, etc are stored. On previous versions of TWRP for phones I have had, you could wipe system, date, cache, etc and it would always leave internal storage intact. Ergo, after wiping, you could navigate to your downloads folder and find the ROM you wanted to flash. The issue I had was that I wiped "system" using TWRP and it wiped my "internal storage", meaning my downloads and photos and everything - leaving me with no ROM to flash.
You answered my question perfectly toward the end with this

I come from a series of phones where this was not standard behavior for ROM installers, so failing to wipe system would lead to a dirty flash and almost assuredly cause issues. Thanks for the input, I will just do a data wipe from now on.
You shouldn't count on roms wiping system automatically.
A well established rom like pure Nexus for instance does not wipe system at flashing, leaving it up to the user to clean or dirty flash.
Always read and follow the installation instructions that come with the rom and you should have little problems. If there aren't any instructions, stay away from the rom is my advice, especially of you are a new user.
As to your question: go to the wipe menu in twrp. Then do an advanced wipe. Check every box except internal storage and wipe. Then proceed to flash your rom.

This is exactly what I did when it wiped the ROM file (and all photos/sms backups) from my internal storage. That's how I have always wiped before flashing a new ROM in TWRP and this is the first time it ever wiped my internal storage, hence my question. I think I'll just stick to ROM installers that perform a system wipe. I plan on running the odex stock based ROM I just installed for a while anyway.

Sorry for assuming you're a newby. Last time i wiped that way in twrp (June 2016) it left my SD card alone. Maybe you checked the wrong box?

No worries, I appreciate the help either way. I suppose it's possible I checked the wrong box but I am very diligent about that because I have REALLY screwed myself over with that in the past. I accidentally wiped internal storage once or twice on my HTC One and had to RUU back to stock, losing everything including root. Luckily recovery is quicker and easier on the 5x (and the phone is brand new so it had no pictures on it).
I'm afraid to try it again even with a nandroid since the recovery files or stored on internal storage so wiping that would leave me SOL too. Like I said, I'll probably just ride on this ROM until the Nougat or so and then make a full cloud backup before trying a full wipe again.
Wiping system did not erase your files. /system is read only, so you nor your apps can store anything there.
I respectfully disagree with @peltus. In those parts of XDA where I "grew up" a dirty flash is a rom flash without wiping data. And I would be grateful for a link to a rom where the installation script does not involve formatting or wiping /system.
I could be wrong but I believe TWRP's wipe of data is without data/media.
Internal Storage wipes the entire data partition.
One if these days with more time I'll give it a try

BONUS: What is a data/media device?
https://twrp.me/faq/datamedia.html
The relevant part:
Since /data/media is part of /data, we pretty much never actually format the data partition. Formatting data, of course, also removes the media folder that contains the internal sdcard. When you choose a factory reset [or wipe data], instead of formatting, we use rm -rf commands to remove all the folders except for the media folder so that we can remove all of your apps and settings while leaving your "sdcard" intact. In TWRP we also have a wipe internal storage option that rm -rf's the media folder and a "Format Data" option that formats to recreate the entire file system in case something goes completely wrong or to remove device encryption.
