[TOOL] G2X Cleanup Batch * WARNING * WILL FORMAT INTERNAL SD

mansa_noob · Apr 9, 2012

If you are going to flash and ICS ROM after this tool please make sure to first install a GB then ICS otherwise your SD card will not be accessible. I am trying to find a fix but it has been illusive. This statement will be removed once a fix has been found and OP updated.

Now with CWM Touch!

This method uses NVFLASH to recreate all partitions and formats them, thereby getting rid of the file allocation pointers and hence renders data inaccessible without effort.

Note: I have never seen a file come back to life or its data affect other files without effort on the users part or a temporary glitch once the partitions and pointers have been overwritten. Please post a reply with evidence if you have seen it.

Benefits:

The contents of the zip file can be used to super clean G2X before a new ROM flash. This tool recreates all the partitions in the phone so wipes the pointers to all files (everything). The method it employes has existed from before. The files here will stop short of pushing a ROM, so that you can push your favorite ROM.

Prerequisites:

G2X (Will not work on O2X due to different partition table)
Desire to have a clean install of your favorite ROM
Backup your data

*** WARNING ***

This tool will wipe both phone internal memory and internal SD card. External SD card content is safe.

Don't say you haven't been warned!

What to do:

Download the attached Zip file.
Take out the battery (assuming you have backed up your data on external SD card, computer or elsewhere), connect the device via USB while holding VOL+ and VOL- together. Don't let go of the volume buttons until the device is recognized.
(I typically leave Device Manager open to see when it shows up in the list under "USB Controllers").
Launch flash.bat, sit back and wait until the process finishes (generally a good idea to open a command prompt, CD to the directory and then run the file).
Unplug, put battery in, reboot into CWM recovery (pushed by this tool) by holding VOL- first, then pressing and holding POWER).
Flash your favorite ROM.
Enjoy!

I made this package because I could not get the bluetooth to work with G2x GB 2.3.3 (and below). The issue was a disconnect problem where both the phone and headset would still think they were connected but in audio would not be routed for a call or media. After this procedure my phone has not had an issue for almost 3 weeks now. I have tried it with two ROMs and 3 different headsets without any issues.

I guess I will not toss this phone after all

.

Putting it out there in the hope that it may help others solve some of their issues as well. I suspect bad data stays in places not touched by other methods.

Your comments are most welcome.

[Update]

Klathmon has made an newer version with CWM 5.0.2.8. RP by Klathmon can be found here:

I have tested the windows version but linux one is untested. Use at your own risk.

[Update]

Now with CWM Touch!

Thanks to everyone who has contributed on this thread with a drive to positive change! You work/comments/suggestions are very much appreciated.

[EDIT] The zip file should be fixed now. Darn work machine does something to the upload.

was just about to flash the new hellfire rom and saw this tool! will try it out and see how things go
edit: yeah corrupt zip on my end too.

kesara · Apr 9, 2012

The zip file seems to be corrupt. Could you re-upload plz

khanggle · Apr 9, 2012

worked great on my end, no problems.

The real test is how stable your ROM would stay with this method to wipe than any of the other methods.

I guess only time will tell

wow this method really blaze hellfire much thanks to your( you) & (rom dev)

buru898 · Apr 9, 2012

Ohh I like this. Thank you for sharing

This thing is faster than nullifier, and I especially like how you don't need to be in CWM to use it. It just seems like doing it in "update mode" would allow better manipulation of the phone's internals.

so this tool DOES format and nullify in addition to recreating the partitions?

deleting and recreating partitions does not remove data. only by writing over existing data can you get rid of it (like nullifier does)

He states in OP that it doesn't write anything, therefor doesn't "nullify". It formats and partitions.

Actually you are right. Deleting, recreating and formatting partitions does not get did of the 1s and 0s, so in that sense the data is still there. However the pointers are gone, and hence even though the data is still there it can't be accessed without effort.

What do you think the nand has on it when the device is shipped... I can assure you its not ask zeroes!

Well no, it has a next to worthless version of android

Also, the point he was trying to get across is that it would be better for you to present the script for what it is and not try to compare it to other scripts that do something entirely different. You do kind of imply that you accomplish the same thing as the Nullifier script and more, when in fact you simply do something different.

Some may and probably will prefer your script, at least for specific purposes, while others will prefer the Nullifier script.

Done. OP updated to reflect. Thanks for clarifying that. It was not my intention to state that this tool does anything any other does, or does not.

I think we are all trying to do the same thing... get rid of the issues when swapping ROMs like _____. I can't seem to think of a good analogy here

.

DsturbD · Apr 10, 2012

thanks for clarifying the OP, that makes much more sense

and no i wasnt trying to say you were reinenting the wheel, just trying to understand what your tool is actually doing

and also i do understand that it would take effort to get data off any type of storage device once the partition has been erased. i deal with wiping hard drives in a data center all the time. we use a DOD wipe tool that writes 1s and 0s over a drive a minimum of three full times to eradicate the data

but with this tool doing it outside of CWM, it sounds like it may do a better job of it

but i must ask, why do you need to push CWM? what if i have a newer version of it already on my phone?

There is no need to push CWM 5.02. As I said in the OP it is a mod of the script found in the reference. In that script it was pushing default recovery. Since the recovery partition is being overwritten as well you will loose existing one and you need a recovery to be able to push a new ROM. Hence the need to push recovery (instead of using super one click).

As long as the recovery is not bigger than the partition that holds it

we should be able to push a newer version. However I can't leave it empty or people will look for me with a shotgun (myself included

).

I was thinking the same thing but seems easy enough .. add the cwm img to the dir and edit the .cfg file. Hopefully that should get the new CWM flashed

So would it be benefitial or pointless to nullify to clear the data then run this script for a... super clean?

i think it would be pointless unless you are super paranoid

Nobody is twisting any arms here... Use it if you want to, don't if you don't want to.

I saw benefit so posted so that others may benefit as well.

Ok so question, why are you killing all the data on your internal SD card? Why not just the individual partitions that the phone uses? Your destroying data that don't need to be destroyed before flashing a rom...

mansa_noob · Apr 10, 2012

It does not have to be destroyed. I just haven't had a chance to test without recreating emmc yet.

Next step. Likely tomorrow. Would like to test before release.

[edit] BTW, I do want to restate that there is some data that needs to be destroyed which is not being taken care of by other methods. I don't believe it is in the emmc, but rather it resides in one of the other partitions. Most methods out there are only working in the /data, /system and /cache domain.

My original problem (bluetooth disconnect) which happens to be a problem for some in the community even now was only completely fixed by this method.
