suppose i flashed a new rom to my device.. just the custom rom without a custom kernel.. but i want to go back to my stock rom and i have a nandroid backup of it.. is it safe or advisable to restore it via cwm? or do i need odin to get back to stock rom again?
you can just restore your nandroid backup if the custom rom is stock based without flashing stock rom via odin first
if it is cm/aosp based I would flash stock rom via odin first if you used percys kernel or kernel that converts system to ext then you can restore your nandroid backup
if the backup being restored is using the kernel used at time of backup you will get no errors
if the backup being restored is not using the kernel used at time of backup goto advanced restore and restore system and data only or flash the kernel that you were using when the backup was made first

rom yes kernel no - nandroid backup does not backup/restore your kernel
like I said - if the nandroid backup was made say on stock kernel then restore it on stock kernel or if using different kernel to which the backup was made on goto advance restore and restore only system and data

but i am using madteam's CWM. which i think backs up the kernel because there is boot.img in the backup files. correct me if im wrong

it doesnt restore it though - thats why I said if on different kernel advance restore system and data only because if you just do a normal restore your will get a boot.img failure and it wont restore
but you can always try and see what happens

I'm sorry in advance if it has been asked already.
Do I need to perform any wipes before restoring a backup? I'm currently on CM7.2 RC1 and made a backup of it and want to switch to Defy+ CM9 build for a while then go back to CM7.2. Last time I did it (restored CM7 backup after installing CM9) it just stuck on Boot logo and couldn't move on so I had to start from scratch (new installation). Any guides just mention clicking on restore and that's all. Thanks in advance for an answer!
Can anyone help me? I did as I wrote (switched for a while to CM9 GB build from CM7.2 FROYO) then wanted to restore CM7 backup, tried both with and without wipes (data, cache, dalvik) but it just gets stuck on boot logo and won't move on. What am I doing wrong?
You don't need to do a wipe for restoring a nandroid..
I assume you're using the same recovery with which you made the backup..

Thanks for an answer! I made a backup with CM7 (froyo) recovery and was restoring with the one that was installed along with CM9 (gb). So that was the cause?
You flashed the CM9 ROM through recovery.. right??
ROM's do not change recovery.. Its the same for both..

Why don't you try Dual Boot...
refer to the below mentionedlink:
http://forum.xda-developers.com/showthread.php?t=1364659
However, to install CM9 I'm not sure if someone uploaded itsnandroid backup. Please note that to use the backup and restore youcan only use a Nandroid backup as ROM.zip file can not be restored.
What I understand from your post is that you have CM9 rom in zipformat; if this is the case then you can only install it usingInstall from SD card option from Custom Recovery.

Wiping data removes Custom recovery. If the new ROM has aCustom recovery then only it appears otherwise we have to reinstallthe Custom recovery.

I think you got me wrong. I was using CM 7.2 Froyo build and made a backup of it through recovery. Then I installed CM9 GB build (wiped data, installed rom, kernel, gapps) and have been using it for a while then I wanted to switch back to my CM7.2 backup (went to the recovery, choosed restore) and it said restoring was succesfull but when I rebooted it just stuck on bootlogo and couldn't move on. Any idea what am I doing wrong?

Technically, you haven't done anything wrong. What I've learnt from my experience and posts, this is one heck of a weird phone.
Might be a chance your backup is corrupted or incomplete (highly unlikely bt I've seen it in a device)
Or some other glitch which m nt sure of..

Well as I said..this phone definitely acts senseless sometimes.. a data wipe in my case didn't remove the recovery or bootmenu.
Even reported it in the app thread..

Now, I understand your issue.
Try using below mentioned steps:
1. Boot into latest/custom recovery;
2. Wipe data/cache;
3. Restore the complete Nandroid backup;
4. Now from advance wipe dalvik cache and battery logs;
5. Now reboot the phone.
Please use above mentioned steps and share the results.
Hope this helps!!
Also try to install latest clockwordmod backup.

@MarcinRN
I think your problem is kernel related, if you switch to CM7 from CM9 with GB-Kernel you must restore the froyo-kernel for CM7.

That's the problem. You can find the kernels on epsy's site. Flash the kernel and restore the nand (there are also options in advanced restore if it still doesn't work, don't know if you need them)

Thanks guys I'll try it next time. However, I read somewhere that backup contains kernel too, don't know how much true is in that.
So, I thought I'd see what Jelly Bean was like on the Galaxy S. I have had CM9 on there for a while.
Thought I'd be sensible and do a Nandroid backup - never done that before but seems like a sensible thing.
It all backs up fine. So I reboot the phone and it's in a boot loop. I also can't use the three button combo to get back to recoverly - only the three button download combo works.
What is going on? I only did a backup!
Just to add the complete set of steps. I have the latest stable CM9 installed already.
Boot into recovery.
Select backup/restore.
Select backup.
Wait for backup to finish.
Back one screen.
Reboot phone.

I reflashed using stock 2.3.6 and Odin and then I could restore from the Nandroid backup.
Bit weird all in all. I could understand this if I had flashed or restored something, but I just did the backup!

Its possible when you reboot phone, your new settings might have taken effect that were there earlier . ( Normally for a complete change of ROM, you need to wipe before and after flashing a ROM, failing to do so, can have some effect when phone is rebooted. )

Stock kernel can be flashed by downloading hells fusion #50 kernel from dev section
when you flash hells fusion #50 kernel in cwm with system mounted select step 1 to flash stock kernel
Backup and restore options are found in cwm
simply select backup to backup
and restore & select backup date to restore

make a back up of your stock rom via cwm
download stock kernel from this link
https://mega.co.nz/#!LM4GUJ7D!UCxceA1wW2dQmxFezwC-6Re6xQZ5q07LU0ZrPZX45Ck
extract its boot.img put it in the root of sdcard then download kernel update.zip you would be able to find it in xda put this also in the root of the sdcard.
to come back to stock first flash kernel update.zip after that reboot your device and see which kernel is there in settings if its dell something then reboot into cwm recovery in restore option click advance restore and then restore everything except boot one by one.
if helped press thanxx

Got backup to work. But still unable to get custom rom aka update.zip to get past bootloader. Anyone kno how to fix this.
TeamBlaze
If you're talking about the update.zip made from Titanium, it is NOT a custom ROM.
It is simply a backup of your applications (and some settings) you can use to flash after flashing a ROM to 're-load' all your stuff.
If you get your current ROM configured the way you like it you can then create a nandroid to restore it later if that is what you want. And without any info on what version of Android you're on, what ROM you're on, or what version of the recovery you're on there is no way to tell you where to go from here.

Never tried that (make ROM from recovery in philz) myself.
I just make and restore loads of backups using Philz and TWRP. I consider a full backup (complete image(s) of all phone partitions) to be my ROM(s).
I would bet that with what you're doing that if, after you flash your custom made zip (and before rebooting) you stayed in recovery and then flashed (install zip) of the same recovery, rebooted back to recovery and flashed the kernel it may work.
Rebooting the recovery (or a battery pull) often clears out hangs.
Did you tried enabling se linux context from backup settings?

I want to make a backup of the original kernel that came with my G2 D802 32GB just in case I need it in the future if I mess up something.
I read that flashify can make a backup of the kernel, but also read this program can brick the G2.
Any other ways to backup the kernel of my original stock LG rom?
And how to restore it in the future if I need to do so?
Thanks a lot!

If you're rooted and have flashed twrp recovery all you have to do is back up the boot partition then you have a back up all you need to do is if you want it back just boot into recovery and restore the boot partition it's not really having a flashable kernel zip but it's one way

¡Perfect! ¡Thanks a lot! :good:
EDIT:
Two questions though.
Using that method, if I restore the boot then I would lose my custom recovery right?
Also, I've read that doing backups through TWRP or CWM doesn't backup the kernel installed at that moment. Is this true? Because if it's true then doing that backup wouldn't make a backup of the kernel.
Thanks!

First question the answer is no you won't lose your recovery and to answer the second question I know with twrp it does back up the kernel I do it with every custom ROM I flash I'll back up its kernel before I install a custom one just so i have it and decide to go back to it now with cwm I'm not sure I only used cwm for a short period of time and wasn't happy with it I prefer twrp
