[Q] Problem with data2ext

hey guys, i have a smiple question, I am running Cyanogen7rc2 with data2ext applied. Now if i wiped data and it formatted everything, and i format sd card and sd-ext, i get this "(bad) installition aborted" when ever i flash that rom. Can anyone explain this to me in greater detail?

1st what version are you running??? If your able to nand back to when you had data2ext working do so. 2nd if you wipe sd-ext more than likely you'll end up in a boot loop. Also if you just wipe everything and flashed the rom without flashing the data2ext zip right after you might receive that msg. After you restore a nand always reflash the data2ext zip. If your rom is functioning fine and you want to update to a new one. Reboot into recovery make a nand+ext backup then flash the data2ext zip and reboot. Then reboot back into recovery and to keep all of your data just wipe cache & dev-cache then flash the rom then the data2ext zip and reboot. If your rom is running fine and you wanna do a fresh install do the same process of making a nand+ext backup then reboot. Then go back into recovery and wiped data,cache,dev-cache. "Don't wipe sd-ext". Then flash the rom & right after flash the data2ext zip and reboot. You will have to setup the data2ext again threw terminal or adb. This is what I do no guarantee it will work for you if your running cwm but it should. The reason I say this is because I'm running data2ext ext2 gf's mod and I'm using Ra1.7. Hope this helps. Also you might want to redownload the rom as it might be a bad dl.

That was a ginormous explation! thanks!
Im running dataext4 v4.
So let me get this straight, if i wipe data data/factory reset it wipes the partion off the sd card, or no?

Na not wipe it out as in making the partition disappear it just removes the link you had to it threw data2ext. Because you wiped all of the data from it. Your partition remains but the link is removed. Data2ext ext4 or ext2 wont carry over if you wipe data.

You might want to consider data2ext ext2 "IMO" It performs better. I've read a lot of posts about users having problems with ext4. Its a know fact ext2 can cause data loss if you do a battery pull or improper shut down. But I've been using it for quite some time and I've done batter pulls galore and have lost no data just had to boot into recovery and wipe cache & dev-cache and reflash the data2ext zip and I was good. Also if your not s-off I recommend it when using data2ext and just in general.

ok thanks ill do the data2ext2 and try that out.
So one last thing and im all good. the only way you can erase those partions is if you format the sd card, through a computer program?
ah man now im stuck, i nand back to a stock back up i had, then formatted my sd card through my computer
then went to recovery to flash CM7rc2 and i still get this (bad)installition aborted. do i need to re enable the data2ext in my stock rom, then flash CM7.

You can threw a computer program or threw your recovery.

Backup all of your data.
After you format threw your pc then format it threw your recovery. Then re partition your sd to 1024 ext2 or 1024 ext4 0swap and the rest fat. Then place all of your data back on your sd. Then wipe data, cache,dev-cache and sd-ext. Then flash your rom of choice followed by the data2ext zip and reboot. When you reboot you will have to resetup data2ext threw terminal or adb.

cheers to you man, hope this works. so as long as i dont run that command in adb it wont push the data over to the ext, though it is always partioned?

Yup your right. Even if you flash the data2ext zip it wont activate until you tell it to.

[Q] data2ext: Rom to Rom

Hey my xda'ers. I apologize with the bombardment of questions i have recently, theyre all things i have looked into and couldnt find exactly what i needed.
Its an easy question for those who use data to ext.
I had to go back to my backup (stock rom) to update my prl. This was from CM7.03 with data2ext applied. In recovery i wiped data/fac reset., cache partion, format boot, cahche, data, system, and sd-ext (this part is what i might mis understood) But anyway. I did what i had to do then decided to flash an AOSP rom. So in recovery i did the exact same wipe as above. Flashed rom, gapps, and data2ext4 v4. I didnt partion my card cause i though it was already partioned from my CM rom when i did it then (correct?) so i booted in and ran all the commands i needed for data2ext4 and it didnt run down my internal memory. so i decided to partion my sd card (again) to see if that would fix, it did NOT.
So can anyone shed light on what i did wrong and if i need to format and start over!?

When you were running data2ext you were supposed to do a nand+ext backup first and then flashed the data2ext zip and then rebooted. Then you were supposed to boot back into recovery and only wipe data,cache & dev-cache and then flashed your sense rom of choice. After you updated pri/prl power down and reboot back into recovery and make a regular nand and reboot. Then boot back into recovery and wipe data,cache & dev-cache then restore your nand+ext you made and then flash the data2ext zip and reboot. When your running data2ext ext don't wipe the sd-ext it will more than likely result in bootloops and could make your nands useless. Also your partition you setup on your sd should still be there unless you reformatted your sd. So when you wiped the sd-ext you essentially wiped out your data2ext link. And as far as if you have to start over well you could try to restore your nand+ext if you made one and then flash the data2ext and reboot to see if it will. If not then yes. But when you get it all set back up just make a nand+ext backup and remember not to wipe the sd-ext.

Oh and you don't have to reformat your sd your partitions should still be there as long as you didn't reformat your sd. You can just flash a fresh copy of your rom and just resetup the data2ext mod. But remember to make a nan+ext backup. Also always remember when you do and nand+ext backup always flash the data2ext zip and reboot. Then go back into recovery and continue. Same with restoring a nan+ext always reflash the data2ext zip right after.

im using CW 3.0.2.8 and it doesnt say nand+ext, so i assume you use RA?
But i also assume CW backs up the ex if it exsits?
Edit: also you say flash it then reboot, then go back into recovery.
When i reboot do i need to enable it while im there, or just simply boot and go back to recovery?

yes, CWM automatically backs up ext.

Thanks Il Duce!

From which part are you flashing the data2ext zip from???? And my bad. I'm using Ra, I should have asked you what recovery you were using. The same applys. And thanks duce for the cwm info.
Root/Hack-Mod_Always *

From the rom i had enabled with? yes. Cause i dont know how to disable it haha

If you already have the mod enabled and you want to do a update the same applys. Roms, kernels,etc. And since cwm already backs up the ext, then after you do the nand just flash the zip and reboot. Same applys for an update for pri/prl. And to disable data2ext in terminal do this
Su
data2ext --disable

[Q] sdcard help!

i was running cos-ds when i decide to try a new kernel: auto-boot-2.6.35.13-farmatito-pershoot-ds-BFS+-20110518 (1).zip . So i went to recovery (cwm) wiped cache partition and installed the kernel from the file menu. when i rebooted all my apps had gone since they had been on the sd-ext. when i checked the sd-ext under settings>storage and scroll down to sd-ext it says unavailable. so im wondering if i wasnt supposed to flash it via recovery. the previous times iv tried flashing a kernel it has worked. how do i get my apps back? is the sd corrupte and do i hsve to re partition? what do i do?

well im no pro on flashing kernels but im pretty sure your supposed to flash them after flashing a rom.... so maybe thats something to do with it...? since you lost all your apps anyway try to re flash rom than that kernel right after and see if anything happens... maybe you need to have a specific ext... 2,3,4 who knows.. lol sorry for your troubles

Sometime it's best to wipe the SD card and re-partition your SD card. I tipically do it when I flash a new ROM. Then re-install the apps.

i agree!!! every once in a while its a good idea to re partition your sd card because it's more like a complete wipe. sometimes ill even do an mtd removal here and there.. (i use custom mtd for my SenseLX rom )

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

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.

[Q] Partitioning and CM

Hi,
I constantly run into "not enough space" problems and the phone starts to get really slow due to this.
So I tried everything possible with my rooted nexus, removed apps with Titanium and so on.
But to no use, Dalvik Cache alone is over 60MB.
So I read that you can partition your SD-Card and move stuff from the phone over like the cache and app-storage.
Also I want to install CM for the first time cause I like to have additional options with the kind of kernel. Like support for battery calibration.
I'm a bit unsure about all this.
How many partitions do I have to create on my card?
What size should they be? (card is 16 GB)
How do I install CM with all this so it uses the partitions?
Is there a DAU step-by-step tutorial for this you can recommend?

Usually a 1GB ext4 partition would suffice. Some use smaller, some bigger, but 1GB is about average.
You can use Gparted to format it if using Linux. Otherwise I'd recommend installing 4ext recovery on your Nexus and use that to partition your SD Card. You could also use Amon Ra recovery if you have it, but avoid using cwm recovery to partition as it can cause corruption.
Finally what version of CM are you using? If BCM CM9 then that has mounts2sd built in.
If CM7 then you can try a multiple of options, including s2e, links2sd, darktreamer or even mounts2sd.
Everyone has their favourite, but I'd recommend you start with s2e which you can download from Google Play. It has a handy GUI.
Ensure you take a full backup of your card before partitioning it. Especially unsure you have good backups of your photos and music.
I use titanium backup for backing up apps. Use this before backing up your SD Card, so that your backup contains it.

Thanks for your reply.
It is my productive phone so I need a stable and fast rom.
Thus I plan to use the latest stable cm which happens to be 7.2 if I'm right.
I'm running Ubuntu on my desktop so I will def. use gparted
So do I get that right:
- wipe my card and partition it with gp
- then wipe my phone and flash CM7.2
- then install s2e (or else) and setup to use the partition

That's right, but imo it would be easier if you install another recovery and do all steps directly from your phone. Also its not necessary but recommended to fully wipe your card, you can just create the ext partition and maintain the other things you have.

what recovery can do all this?

There are lot of them, but I like 4Ext recovery

Okay what I actually did was:
- install ROM Manager
- install clockworkmod
- install Cyanogen via ROM Manager
- clear all caches and storages via the clockworkmod
- partition via clockworkmod (no swap)
- reformat the partition from ext3 to ext4
- install s2e
- choose mount-to-ext4
- reboot
- select what to move (no download cache)
Thanks to all!

Try do download an app from Google Play or update an app when using S2E and see you have any problem (e.g., reboot or can't update error message). I had problems with S2E when using CM7.

I really recommend you to stay away from Clockwork. I had a lot of problems with partitioning.
I thought I was a faulty SD Card ,so I threw it away but I was the recovery fault.
I have been using 4EXT Recovery for a while now and I still have encounter my first problem.

Yes I read that too somewhere else, that is why I formatted with gparted again.
Works fine so far, no problems.

i can't restore a file back up (back up by 4EXT) by CWM 5.0.0.2.
It don't work "restoring sd-ext....."

Use 4ext recovery to restore your 4ext backup
