CM7 nandroid backup fails

DesireHD, latest clockwork, latest cm7nightly. When I go into recovery, nandroid backup fails on mounting SYSTEM partition. Any ideas? Tnx.
edit: system is ext4, latest rom manager installs obsolete recovery that doesn't support ext4. bleh.

[Q] Recommended version of CWM Recovery ?

Hi all,
the last few days, i did extensive reading concerning the whole matter of downgrading, rooting, s-offing and flashing a custom rom on my new DHD.
All steps are clear to me except one: which version of Clockworkmod Recovery should i use ?
I'm planning on flashing revolution hd where i supposedly can use either 2.5.1.3 or 3.0.0.6.
Am I right in the assumption, that its best to just use 2.5.1.3 since many modifications need this version to work. Where would i get it from ? If i download rom manager from the market, won't it just flash the latest version of CWM recovery (3.0.0.6 or .7) ?
And what makes the unofficial version "2.5.1.2 r2" from paul of modaco forums special ?
One last question: say i create a nandroid backup with 2.5.1.3 and later upgrade to a higher version (3XXX or whatever), will i still be able to restore this previously created nandroid backup ?
sorry if all these questions got answered somewhere else already, i searched but couldn't find any answers to these specific questions.

I'd stick with 2.5.1.3, everything works with it and I think if you create a backup with it and then upgrade to 3.x.x.x then it won't work when returning to your backup.
Personally, I don't see many benefits to using 3.x.x.x at all
Ah sorry, didn't notice your other question, Just download Clockwork and it will get it for you. If it wants to get 3.x.x.x then you can easily find 2.5.1.3 on a google search

thanks for the answers
just noticed that leedroid needs 2XXX, too. so i'll just get the older version.
thx again !

Actually you can restore nandroids from one version with the other. The important thing is which >filesystem< does the rom use.
I tried backing up stock rom with cwm3 and tried restoring but didn't get past boot. Reason was it was restoring it to ext4 partitions, which the stock rom doesn't support.
Then i booted cwm2.5 using fastboot and restored with that instead... no problems.
peace!

so you are saying that cwm2.5 always creates ext3 partitions on restore, and cwm3 creates ext4 ?
if that is the case, can i flash the newest revolution hd roms with cwm2.5 despite the fact that they use ext4 ?
p.s. sorry @ mods for creating this thread in the wrong forum...

What I do know is that cwm2.5 supposedly can't mount an existing ext4 partition whereas cwm3 can. Even if cwm2.5 lacked the support the rom you're talking about could still be flashed to ext3 and booted as ext4 (since it's forward compatible). But once it's used with ext4's new features (like extents) you're stuck.
Wiping a partition in cwm3 and then mounting it mounts it as ext4 (according to "adb shell mount". Booting cwm2.5 using fastboot and formatting same partition results in a ext3 partition.
Sorry if I confuse the matter further

no problem, i think i understand
flashing revolution hd with v2.X will create an ext3 partition, but the files that revoHD is creating later on will be kind of ext4 (does that even make sense?). but when i wipe everything it will be ext3 again, and restoring a CWM2.X backup with CWM2.x shoult be possible, is this correct ?

Sounds right to me Yeah it's a feature of ext4 that you can mount ext3 as ext4 but when you do so using the new features you can't go back (automatically atleast) and the partition is now ext4.
Restoring a 2.x backup with 2.x should always work since 2.x can only make backups of ext3 in the first place...
peace!

you can use 3.0.0.6 for both. Trust me.

[Q] quick CMW3.x.x question

My endgoal is to flashsyndicate to my Epic.
I started with DI18 and flashed (via recovery) to EB13. Which is where I currently am. I would like to us Titanium Backup to save all my data but I need root. Its my understanding that when I run the CMW 3.x.x one click I am going to have to immediately flash to an ext 4 compatible ROM, and therefore lose my EB13 data? I was thinking that I could use noobnl's root, backup with T.B. THEN CMW 3 one click and flash syndicate followed by the dual fs kernel? Is this sound reasoning?

You can go to cwm 3 without flashing an entire rom. You would just need to flash a EXT4 compatible kernel. The cwm ext4 conversion process backs up and restores your data so as long as you flash a ext kernel you should be good to boot into stock then backup then proceed with flashing your rom.
Or you could one click with cwm 2.5 then backup, then run one click with cwm3 and convert. This is what I did.

Awesome! Thanks for the help

[solved] Help! cannot restore stock rom!

few days ago I just flashed cwm recovery and made a backup for every partition, after that I flashed the cm7.2.
but now when I want to go back to stock, I cannot restore the backup. it seemed that the recovery cannot format the partitions into rfs. (even I used the rfs+ext4 recovery)
anyone has any ideas?

Did you have an ext4 partition when you did the backup? I've experienced problems with the CWM backup a couple of times because it's not getting along well with ext4 partitions so I had to go from scratch a couple of times because I couldn't do a restore. For Galaxy Gio, I would recommend you to use Titanium Backup instead of CWM Recovery from now on if don't want to get into trouble with backups and stuff.

Just flash a new firmware via ODIN.

thanks for replies but my original firmware contains chinese which cannot available here

Try this:
1) flash some stock multi-package firmware (that would format your FS to rfs from ext4); shouldn't matter much what firmware you flash, just something Gingerbread-ish to allow CWM to work, as you only need it to format partitions
2) flash CWM (or install via update.zip method from recovery) that works with stock firmware (I believe it's the one with rfs+ext4 support but you better check in CWM thread)
3) restore your stock ROM backup

Have you checked Samsung firmware websites like samfirmware to see if they had yours?
If not, there are instructions here on creating an Odin flashable backup, which you could do if you have access to another, unmodified Gio.
Otherwise, look into the workings of CWM. You may be capable of DD'ing the nandroid files manually, but don't take my word for it.

thanks everyone who replied, i finally figured out what's wrong.
It turned out to be the problem that no CWM for gio could format the partitions into rfs therefore they kept giving me errors when i tried to restore.
and after some trials, I found that the CWM for CM7 (cwm-v2.zip) can actually restore my backup, but with the system, data, cache formated in ext3. Therefore with the stock kernel, it won't boot.
Final remedy: use CWM for CM7 to restore the backup, then flash a custom kernel for stock rom.

Which kernel? Im in your exact situation, i got the cwm you mention and it restored the back up and flashing the kernel for stock rom with lots of options claiming to support ext4 i get boot loops. If you can tell me what kernel you booted with i will be very grateful. Tomorrow is my daughters bday and i need my korean gio with different wifi hardware to tether to my tablet for ideo chat, which only works with stock. Thank you.

[Q] Galaxy S3 I747M Rogers ROM unlocked and rooted How to Backup ROM to SD?

Guys,
I rooted GS3 using CFroot and Odin, SuperSU is running. I have i747m Rogers canadian version. How do I backup the current ROM?
I downloaded 'stock' ROM from SamMobile I747MVLUFNF2 for backup purpose. There is so many posts and videos everywhere on how to do backup of current ROM and I am very confused, and dont want to mess this phone up. I downloaded ROM Manager but when I boot into recover mode I dont have option to backup ROM, only restore from SD, reset, restore from flash, wipe cache , there is no backup option. I pulled the battery out and tried many times it did not see backup ROM option.
This is what I want to do, what is the best aproach ?
1. How to backup current Rooted ROM to sdcard, so I can recover if required. ROM Manager I have on the phone is v5.5.3.7. I watched video on galaxys3root.com but he used 9300 GS3 from different carrier.
2. I want to try a new ROM give the phone new life, with all functions working including front camera. WHich ROM do you recommend for my phone?
I also installed ROM Manager, Titanium Backup, Terminal Emulator, Nandroid Manager, and BusyBox. Not sure if I need these apps, but they are there.
Can someone point me in the right direction?
Thanks,

Install the latest version of Philz Touch or TWRP for the d2lte, boot into recovery, create a backup and save it to your external SD card and computer.

Thank you.

Thanks! Philz Rocks, it is exactly what I was looking for !
I loaded Philz Touch 6.48 for d2lte, and it worked great. Did full backup and I am ready to flash.
DO I NEED to keep ROM Manager for anything ?

I don't use ROM manager. I just flash a custom ROM and a quick reboot app which gives me the option to boot into download mode, power off, reboot system, or reboot into recovery.

Thanks.

Hi audit13,
1. how do I copy backup from SD to computer. These are hidden on SD card and not visible even to Android? Is there a trick to it?
2. Which ROM do you recommend for Galaxy S3 i747m (original Rogers now unlocked), so all the functions work well and stable on the phone? I was interested in CM11 Nightly.
This is ALL new to me, first time doing it.
Thanks again for you answers,

Both CWM and TWRP recoveries create a directory in /sdcard named either clockworkmod or TWRP and store the backups in a subdirectory. It is likely that PHILZ does the same. There may even be an option to store the backup to the external sdcard at the time of creation.

TWRP stores the backup in a folder called \TWRP\Backups\serial#ofphone\name of folder.
I'm not sure about CWM as I don't have a phone with CWM at the moment.
I run the Liquidsmooth milestone on a Nexus4 and Moto G because I love the dark theme.

I have a device on TWRP and another on CWM, I just didn't bother with the full path because he is on PHILZ, as you recommended, and I could not check that path.

Thanks to you guys, I have successfully converted GS3 stock Samsung 4.4.3 GS3 (rogers unlocked) to Philz Touch with CM11 rom, works great on Bell (Virgin) network.
But I have a question;
I would like to try TWRP If I want to switch from Philz to TWRP recovery instead, how much is involved to make a switch? Which recovery is more popular and better supported?
Is it as simple as flashing in Odin proper twrp .tar file for my d2lte?
Thanks.

If there is a flash able zip for twrp, you can boot into philz and flash it.
Any backups made with philz cannot be restored with twrp.
I tried twrp and switched to philz due to issues I had flashing custom roms with twrp.
I don't have my i747m because I have it to a relative in May so support has probably improved with newer versions of twrp.

Philz Touch to TWRP recovery migration.
I flashed TWRP over Philz Touch using Odin. I am going to wait until newer CM11 nightly comes out to test it, but Philz seems more intuitive to me. I can always flash back to restore backups I made with Philz Touch.
Thanks.
