[Q] RomManager issues with N1: soft-bricking when creating backup

Hello all,
I have successfully installed CM7 on my Nexus One. However, I have the following problem with CWM: if I ask it to make a backup from within the recovery or from RomManager, CWM (3.0.0.5, latest version available apparently for Nexus One) makes the backup, but after restarting, I am stuck on the CM7 splashscreen: I see the blue Android on his skateboard and the arrow goes around in circles (left it going for 15 minutes just to be sure).
Also, on a sidenote, when I made the initial nandroid backup in CWM from my stock Froyo, after the backup was done I had to go in RomManager and "fix permissions", because all my resident apps kept crashing with "forced close" errors. No idea where that came from. Restoring that backup did the same thing as well. I did not investigate that issue any more though as I was on my way to a CM7 upgrade anyways.
So I now have a perfectly good install of CM7 running, but I am scared of doing a CWM backup. This is far from an ideal situation, and I would love to be able to resolve this
Thanks for any help

Anyone? I really am quite upset with this situation

Use this instead?

Thanks, I will try it... though I have to admit I am nervous at the idea of having to again reinstall everything. Crossing my fingers!

Uh oh? It is just a custom recovery, no need to reinstall everything. You only flash the recovery and do the backup you cannot now with the broken CWM. (For my phone, there are even flashable zip files so you can switch b/w CWM and AmonRA "on the fly" via flash zip from recovery, not sure there are some for N1, try to search. )

Actually, the current problem I have is that after performing a backup, my phone doesn't boot anymore. The only solution I have at that point is to re-flash a complete ROM (flashing the backup doesn't work either), thus losing everything.
In short: making a backup means I then have to format and said backup is unworkable...
Which is why I am nervous at the idea of trying to make such a backup.
On a sidenote, RomManager is indeed able to flash both CWM and RA recoveries for N1 directly, which is quite nice indeed.

I still do not understand why all this. Just flash a working recovery from fastboot (should press power and trackball IIRC on your phone). (And obviously do not use CWM to perform backups when it bricks your phone.)
On another note, flashing removery via ROM Manager resulted in bricked phones for many users, would avoid it personally.

[Q] (Clockwork Mod) What is Nandroid Backup and How Does it Work?

This is a noob question, but I have a bit of experience under my belt just so you don't have to worry too much about using "confusing" terminology.
I have rooted/ROMed many devices in the past and have heard guides talking about doing a Nandroid backup. My question is how exactly does it work? Say for example: I am on the stock ROM (rooted of course) and I do a Nandroid backup while on stock. If go to say Cyanogen and I don't like it can I just restore from my nandroid backup like I would flash any other ROM to go back to stock. And if that will get me back to stock does it also preserve all of the user data that was in that ROM when it was backed up?
Any other information about about nandroid backups would be appreciated. Thanks in advance!

From my understanding, the backup backs up all the stuff on your phone EXCEPT for what's on the SD card.
The idea is that you do a back up. Then install a new rom that you want to try out. BUt you don't like it, so you just restore the backup and woolah! your old phone is back along with all your settings, data, etc.
I'm not sure why it's called a nandroid backup, but from what I gather, you can do it with clockworkmod, just boot into recovery. And use the backup and restore option.

That was my understanding as well. I just wasn't sure on the situation with the user data (or the backup in general really). So all it takes is a nandrid backup to revert back to (rooted) stock?

A Android backup takes all the files on your device and saves them as a data.img,system.I mg,cache.I mg,user data,and recovery.img. It is also restorable through fastboot. It can also get you out of a tough spot. Say you are messing with a new theme and it causes your device not to boot up or causes unwanted problems. You can restore a backup to a time when your device was working correctly.

this is true unless you do a nandroid+android_secure backup. this also backs up your external app data

Yes you're correct. You can restore but just remember some app might have ext data in sdcard. If you don't delete it, when you restore you'll get the same as before

So if you want to restore say just your data can you just delete the images you do not wish to restore from the backup folder and it will just keep the ones you have? Or won't it work at all if you start deleting images?

i wouldnt tamper with a nandroid backup, but if you have clockwordmod recovery, that is possible. clockwordmod recovery gives you the option to restore one of those images (but only one at a time).

does a nandroid backup include your kernel?

It does! It's a compelete "snapshot" of your phone with all apps/settings etc.

Does it also backup the stuff which has been stored on the external ext2-Partition, which is mounted to enlarge the space for apps?
Same with restore of this nandroid-backup. Will it also place the backup again to the same space?
As I know there's a (symbolic) link put into /data which might get problems.

If you install another ROM with different kernel and then you want to go back to nandroid backup, does it work ?

Nandroid backups
I was wondering if the framework is saved as well. I recently updated to the ICS firmware and am wondering if I restore with a backup from the old GB firmware will that be restored as well or will it still stay on the ICS? From my understanding ICS firmware will run previous versions

will nandroid backup (made from cwm) un-brick your phone if say, you installed a custom rom via cwm and it bricked it?

Yes,It restores all data and apps nandroid backup is a mirror copy of your phone.after restoring you will get your previous stock ROM.

im not sure, i think nandroid backup will unbrick your phone as long as you can boot to recovery. atleast when i installed a roms pach it didnt fully boot, got stuck at bootanimation, no loop, just froze, then i got it back with nandroid backup

I have the latest CWM 5.xxx, but there is no Nandroid backup option.
but only those below';
- backup and restore and under it
- backup
- restore
- advanced restore
- backup to internal sd card
- advanced restore from internal sdcard
Where is NANDROID Backup?

NANDROID??

ok since we getting more roms and have hellraiser over there opening the door. i have ALOT of nandroid back ups.
now having never had to actually use one of these i wanted to know somethings.
is a nandroid like a Rom, i just have to flash over another rom, or from stock and boom i have that Rom back with all my apps and info.
or do i need to load up the rom then nandroid on top of that for it work??
just have never had a use, but i would like to go back to some of my prior setups.

A nandroid is a system restore basically. If you fubar something and can get into recovery you can restore that nandroid to exactly where the phone was before. You don't need to flash anything just be able to get into recovery.

A nandroid will reflash system, data, cache - everything. The only thing a Nandroid won't flash is a kernel if you're doing a major change (e.g. Froyo to Gingerbread or either of those to CM7 - while it's also GB, it requires special kernels.)

ok with that said, you should flash the Kernel before the nandroid to make sure there is a compatible kernel there for the nandroid to use??
basically match up froyo roms and kernels and visa versa for BG before i decide to flash a Nandroid?

Yup, that would be a good idea - since if you restore the nandroid on an incompatible kernel, you'll have the phone be very unhappy. (Will refuse to boot.)

Much thanks E.........appreciate the time bruh.
this can be closed.

I completely failed here E, i tried to restore a nandroid. i loaded the Infusion GB Kernel then proceeded to restore the nandroid and just get boot loops no matter how i do it.
any thoughts??

Hmm I think I need to look at this later in the week. Starting to sound like Nandroid might be broken in red CWM.

i got it, but i had to load the Kernel - Rom - then do the nandroid. but that kinda of defeats the purpose in my eyes....lol
but yea, if you find something that would be cool to know E.

[Q] Need reassurance about backup process

Hi. I've been using a ROM for the last little while (SlimICS), and I like it, more or less. There's a feature in another ROM (ParanoidAndroid, per-app density), that I'd really like to try out, but this ROM also has a lot of features I don't want (tablet mode) and doubt I would like. I use TWRP as my recovery...if I use TWRP to make a backup of System, Data, Boot, Recovery, .android_secure, and EFS, will I be able to flash this other ROM, then restore the backup to go back to my old ROM after I play with the new one a bit? Will the backup of these items bring me back to exactly how it was before, if I do a Wipe Cache/Dalvik Cache/Factory Reset?
Sorry if these questions are answered elsewhere, I'm just trying to make sure that my limited understanding of all this isn't incorrect, in my specific situation.

If you make a backup through recovery, when you restore, it'll be exactly where you left off, settings and all, when you shut the phone down.

When backing up in Recovery, you are backing up the OS and apps. This is called a nandroid. This does not backup anything on the sdcard.
Yesterday, I flashed a different kernel version on my NS. Before flashing, I did a nandroid backup using Reovery. Unfortunately, the kernel failed to load properly and I was stuck in a boot loop. I restored my backup I have done previously, and my phone was back where it was, few minutes before. It is very easy to do and backups/restores and verified using MD5 checksum.
Keep in mind that some apps put stuff on the sdcard. So if you flash your phone to a new ROM, upgrade apps and then go back to another ROM, it is possible that some apps won't work anymore. I've never seen this happen but this is a possibility.

Does restoring TWRP backup maintain all settings, apps, configurations?

I'm considering trying out a different ROM on my T-Mobile Galaxy S2. I've done quite a bit of modifications to my stock 4.1 ROM.
I made a complete backup of my phone using TWRP recovery (both system & data backed up).
Now, if i decide that after trying someother ROMS, i decide to revert back to the stock ROM i was using, can i just restore my backup with TWRP Recovery and all my settings, apps, screens, etc. everying will be restored just like it was before i put another ROM on?
I've been very hesitant to try this for fear of needing to reconfigure everything again.
I assume everythig restores as original but i need confirmation.
Thanks.
