[TOOL] 11/Nov r2: BackToEXT3 - for converting your device, er, back to EXT3

If you have been using a EXT4 ROM and you want to restore a stock ROM that only has EXT3 support, it's a bit of a faff. Introducing BackToEXT3.
This ClockworkMod update zip simply converts your /system, /data and cache partitions back to EXT3. It wipes them both in the process, so you need to have an existing backup / ROM to restore to.

After installing FR12 custom ROM Vanilla Edition on my phone, I wanted to get back to stock so I installed - back to ext3 zip. Then when I tried to restore the stoc ROM, I got the error MD5 mismatch!
I want to specify that I tried a custom ROM before but with ext3, and I had no problem to return to the stock ROM.

Tool worked fine for me. fr10 back to stock.
Md5 error probably means ur nandroidbackup is damaged

Thanks MaBlo, I usually search everything on Google, but this time I forgot, lol.

Sorry guys, please correct me if I'm wrong as I'm trying to get it back to stock.
1. Copy img to ext SD card
2. Reboot into recovery e.g. CWM
3. update BackTOEXT3 image with CWM
4. run nandroid to restore stock image
Am I right? I keep getting stuck at the LG screen

What "img" are you talking about? Nandroid restore is for restoring a previous backup, not for flashing a rom image.
If you want to flash a stock rom image, you need to use smartflash or nvflash, unless you want to flash the 0622 one, which someone made available in CWM format. (Not completely stock though, as it is prerooted etc.)

ok solved, if anyone could delete this post

Updated to include cache partition.

please tell me is there any flashable which can convert to ext4?
It will be useful to convert from ext3 to ext4 before restoring a nandroid backup which was taken earlier from EXT4.

You don't need that. CWM automatically converts from ext3 to ext4 (if the backup is ext4), but not the other way round.

What version of CMW do you have? Did you do a Full Wipe?

And for better compatibility be sure to come back to ext3 with backtoext3.

Im using chucknorris custom ROM..
I already tried backtoext3

Yes, what version is your recovery? Where you flashes ROMs?

Do not use CWM touch recovery and you should be fine!

Maybe you could try to re-root your phone. I had the same problem and I figured it was because it wasn't rooted properly. What program did you use to root your phone?

Im using 5.0.2.0 without Touch.

I don't know what "Tor stock" is..
But when you try to flash Nova, what settings do you install? (In Aroma installer) And what rc version?

Latest rc
Aroma installer on default

As far as I know Nova HD had some issues with flashing with full wipe. You can try to flash it 2 ways:
1. Flash NovaHD with full wipe and then flash it once again WITHOUT wipe. This should do the job.
2. Make a full wipe in CWM and then flash NovaHD WITHOUT wipe.
Hope it helps.

So much smattering out here
formatting /sytem before flashing?
useless... nearly every rom-package runs its own format command for /system, so its bullsh* to do it manually before.
if you want to get sure that /data is ext formatted, just use the format or datawipe option of cwm.
rooting makes problems?
cmon! the "rooting" is just for being able to install cwm, not for using it.
cwm will always have root when its flashed once.
the missing root part in stock roms is missing in the stock kernel, not in the phone itself.
do your wiping/formatting before you flash any rom, if you wanna clear all system relevant partitions.
some rom-flashables are writing into /data and when you do the data wipe after that, it will delete those stuff again.
if you have any bootloop problems after flashing its a kernel or /data problem.
try to mount /data in cwm, if it fails you know what the the problem is.
remove battery, hold vol-down, power keys when you put the battery back in, to get back into cwm and try to format /data until your data partition is fine again.
if the bootloop is still there try another kernel.

[Q] LG P990 - Stuck on LG Boot screen after Nova HD v1.1.0 Installation - PLEASE HELP

Hi,
i've rooted my LG P990 and tried installating a couple of different custom ROMs. Firstly, I tried installing Paranoid android and after rebooting, I get an adroid grim reaper on the screen. I reflashed a few times but still get the same issue.
I then tried installing Nova HD 1.1.0 and just get stuck on the LG logo splashscreen.
I'm really confused and installation reports successful.
Please can somebody help?
p.s installing using CWM 5.0.2.0.

Hi, none of those ROMS booted. However, I did find a 'G2X' ROM running Android 2.3.3 that could be installed using 'NVflash'. This does work.
I really do want an ICS ROM on there though.
Yes, I install CWM using 'Superoneclick' and then factory reset/wipe the device before trying to install the custom rom and gapps zip via the SD card.
Is it worth trying CWM 5.0.2.7 or 5.0.2.8? Please can you provide instructions on how to do this as superoneclick just puts the cwm it has built in (I think).
Sorry, i've not done this sort of thing many times so am quite new to it all.

Hey dude, this happened with me before and I solved it by converting the file system back to ext3 as some roms are converting file system to ext4 , try both converters to ext 4 and to ext3 (I recommend back to ext3) those are the links

I installed a custom ROM, maybe the rom you tried flashing b4 has converted your file system to EXT4, most of Cyanogenmod does so, so give it a try

[Q] how to downgrade from CM7.1 to stock rom 2.3.4?

Hi,
I used CWM to backup stock rom(2.3.4), then I used CWM to try CM7.1 nightly. Now, I would like to go back to 2.3.4. I restored the backup rom. The step i took was:
full wipe
format /system
install http://nigella.modaco.com/files/r2-backtoext3-2x-unsigned.zip
restore backup rom
reboot
After that, I rebooted. There is bootloop. Just wonder if anyone know why and how to solve this? thanks in advance!

When you get back to stock lg from cm you must format all ext3 before restoring. Search for Dr4go tools.

Thanks for your reply.
I tried to use r2-backtoext3-2x-unsigned.zip to restore it.
Can you tell me the correct procedure?
1. enter CWM mode.
2. install r2-backtoext3-2x-unsigned.zip
3. full wipe
4. format /system (i think i dont need this step, right??)
5. restore 2.3.4 backup
6. reboot
Is this correct?
Maybe i should try to use Dr4go instead ofr2- backtoext3-2x-unsigned? thanks

Very simple:
1. Cwm install ext3 zip file from Dr4go
2. Cwm restore your stock backup
3. Restart
Edit: this is the link to Dr4go tools

Get the "old" file which means for the old bootloader.

thanks a lot for your detail reply, a bit busy this week, I will test it in this weekend.
In fact, I dont get the idea of old and new bootloader. I am confused if this refers to different file system ext3 vs ext4?

The bootloader is the first program which starts the phone (or any computer), ext3 and ext4 are different data mgmt systems.
Your case is old bootloader, the new bootloader was introduced by LG with ICS roms. But this is another story.

[Q] Doubt about Recovery (PhilZ and CWM) & wipes

Hi everyone!
Maybe I have a basic doubt, but because I don´t understand, I like have clear this. Yesterday I decided root, replace the recovery and install a custom rom on my Note (N7000). I choose the kernel from PhilZ and install following the recommended method (very easy).
After this all work perfect, I do a full backup of actual system (this is nandroid backup, right?) and after this I install the CM 10.1.3 that also work well. I not rememeber exactly, but following some steps to install this ROM I do before or after install this procedures also: WIPE/DATA FACTORY RESET, WIPE CACHE, WIPE DALVIK CACHE. This procedures are correct?
The device work well, but I have a big doubt because if I boot into recovery I not see anymore the PhilZ touch interface, now I see:
CWM Based Recovery 6.0.3.6
that is other recovery, right? Is normal this behavior? I not understand in what step I change the PhilZ recovery to CWM.
Thanks in advance for all info and help to clear this

This is the CWM recovery same as philz, the difference is that, the version you used before.. It was touch, and after flashing the recovery changes as the CM 10.1 flashed their own kernel...
so it is the same recovery, do not worry
and yes, AOSP/CM roms have their specific kernels, so please do not flash philz on the current recovery...
and one more thing... the process is correct, do a wipe data and factory reset and then format system and preload

Thanks NoteboyTech, yes, I know that work basically like PhilZ, but my main doubt is in what moment of all procedures are installed the CWM Based Recovery. This mean that this CWM are installed in the moment that I install the CM 10.1.3?
Now if I like keep the PhilZ, is safe if I boot again in recovery and install from the .zip file from PhilZ again? or not recommend this?
The wipe: I need made the wipe factory, cache and dalvik before each time that I like restore a ROM or also kernel?
Thanks!!!

You are using a cm rom. Philz kernel Tw doesn't work with cm rom. If you flash philz on cm, phone won't boot.
There is no need to wipe if you just changing the kernel.
If you want the touch recovery, you can install nx kernel which includes philz recovery and is a cm based kernel.

Thanks to all!
Now I believe that understand a bit more
Perfect. This mean that if I like keep the PhilZ as recovery I need install the nx kernel, right?
Now, if for example in the future I like try one new version or actual version of my stock ROM, is safe to download from Samsung Updates website, install from .zip like I do with the CM, and ready, I have the stock ROM. Is correct?
OK, I not need wipe anything for kernel installations, but yes for ROMs, right?
Only data/factory and cache or also dalvik?
This wipes I need made before install the ROM or after?
Thanks for all!

Today I try make a complete nandroid backup, but can be possible that the CWM Based Recovery 6.0.3.6 don´t have this option?
Some days back, with the PhilZ recovery, I can do very easy.
To restore a nandroid backup I need use the same recovery or the generated files are compatible with all recovery?

????
CWM 6 versions are compatible.. it can be restored using any recovery.
Why can you make a nandroid back on 6.0.3.6?

Have a link to read how backup the IMEI number?
Can be possible that I detect that after I made all these changes (change the recovery, root, install new rom, etc) the Serial number of the device has changed? I can change from any area to the original one?

Option to backup efs is in the philz recovery. Or you can use ktool from the playstore to backup efs. This has to be done as soon as you root. There is no point of backup if the imei has already changed.

No, the IMEI is correct, the change is in the SERIAL NUMBER of the device, not IMEI. This can be fixed writing the correct serial number?

Not sure how to correct the serial number.
Ktool is a good tool to backup efs.
