Help: Problem Flashing Any 2.1 ROM's

I cant flash any 2.1 Roms. I could only nandroid restore my backed up 1.5 stock rom. I can't restore my 2.1 Sushi Rom. Whats the problem? I went from Fresh Toast to try and flash a 2.1 rom. and partitioned my SD card in between to a FAT32.

nandroid corrupted? when you say you cant flash, do you mean after a clean wipe and flash, or you cant restore...?

Nandroid work for cm7?

I want to try some kernels for cm 7.1 to see if ocing could help speed up some games. If I don't like them I would like to get stock kernel back and I know I can't use sgs kernel flasher to back up current kernel because cm7 is different. I think I read that you could do a Nandroid and this would back up the current complete setup. Is this true? (sorry can't seem to search efficiently on this Tapatalk and don't have access to a computer). If so does it also backup apps, data and all? Is it done on the backup rom from rom manager or recovery? Thank you for your help.

nandroid backs up everything just as it is. definitely use cwm not rom manager.
you could also just put d/l the stable kernel as a cwm flashable zip.
2 cents

Thank you for your help. Where can I find the kernel?

Don't know for sure (I don't run cm7), but I would check the op of the cm7 thread.

nandroids do not backup kernel or modem.
have you ever made a backup of one set up and tried to restore onto a completly different rom? well if you have then you know there is a high chance that it will bootloop because of a now incompatible kernel. the procedure for a proper nandroid restore is to flash the rom it was backed up on (thus flashing the kernel that is compatible with it) and THEN restoring the nandroid. then it will be like you never flashed away from that rom at all. (this is speaking of tw roms as i have never run an aosp so i could be mistaken about it not backing up kernel on cm7)

Yea, I kinda thought that, but thought it worked for cm7.

Nandroid backup queries?

Hi , some questions.Will appreciate if anyone could take the time and answer.
1. What things are left out in a nandroid backup? Are kernels included?
2. I can't restore a nandroid backup of froyo on GB without flashing a stock froyo build first, is that right?
3. Can I restore a Nandroid backup of GB 2.3.3 (say) while on GB 2.3.7 or any other 2.3.x? If yes, what if I am on different kernel than the backup kernel, can i still do it?
4. Suppose I am on 2.3.x based custom rom (say MIUI) and I restore a 2.3.x based CyanogenMod Nandroid backup, will I get my whole CM back or all my apps/settings of CM on MIUI?
Thanks a lot.

I'm not sure I can answer all your questions but I'll tell you what I've done.
From stock, after making a nandroid backup using CWM, I've flashed a CM7 having done all the usual wipe(cache,etc) procedures and gone back to stock using the backup. Everything is restored, including my settings, old messages, kernel, apps, everything. Be warned, you will obviously lose all the messages and call records that you received after you flashed the new ROM, unless you use an SMS/call log backup app. Same with CM7 to CM9 and back. So if you plan to flash a new ROM, the nandroid should be able to get you back to the exact same state that you were in when you made the backup.
I'm not much of an expert though, so I might be wrong. Feel free to improve on this answer!

1) Yes
2) Yes. Because of change of Linux kernel version.
3) Yes.
4) You will get whole CM back!

Thanks a lot guys...
One more question.
As you said, since I can't restore a backup of froyo on GB (because of linux kernel change), how can i restore a 2.3.x with a different kernel on a different 2.3.x with a custom kernel. Or is this kernel different from a linux kernel?
Asking because you answered the b part of 3rd question as yes (or maybe you didn't answer it at all, i am implying here)

Since GB to froyo is not allowed then CM9 (ICS) to CM7 (GB) should also be not allowed? Just want to clarify, have you restored CM7 backup on CM9?

Cm9 for the Ace still uses the old 2.6 linux kernel(same as the gb kernel) because linux kernel 3.x of ICS is difficult to port for our device!
I have restored a CM7 nandroid backup from CM9 and CM10 and it works perfectly!
Any Gb to gb rom restore works.

Cant restore my contacts,sms,apps and data from Gingerbread nandroid backup
Hi,
I have a similar problem.
Thought of posting a new thread but afraid that i would flood the forum.
I have taken NANDROID backup of my Gingerbread Stock ROM(rooted) using CWM.
Currently im in Cyanogenmod 7.2 for galaxy ace S5830.
I thought of restoring my Contacts,Sms,Apps using Advanced restore from Recovery mode.
Result: "MD5 mismatch" hence unsuccessful.
I tried restoring my Entire NANDROID back up.
Result: The Ace was stuck up with Samsung LOGO.
I flashed CM7.2 again after restoring factory settings.Things work but a blank phone.
So im in 7.2 again. How do i restore the GB Rom? I just want to safely export Sms,contacts and data using .APKs and retrieve back in CM7.2 ????
(BTW CM 7.2 gives me 2 days battery backup at 480 Mhz (underclock) with many useful apps customized as ROM. Quite Delighted. Thanks to Mclaw)

Custom and stock roms use different file systems. Custom uses ext4, stock uses rfs. You need to convert file systems before restoring backup.
Ways to do it:
-flashing stock firmware with odin.
-using the cf-root ext4 manager app, which you can extract from cf-root flashable zip.
Good luck

[Q] How to get back to Stock Rom from ICS!

Hey Guys,
I have a rooted LG p990 from FIDO in Canada. I was wondering if i can get back to stock rom in order to get the ics OTA update.
I have NOVA HD REBUILD 1.1.0 (unofficial cyanogenmod 9) on it currently with the 2.6.32.59-HP-CM9-ICS-SUPERSONIC-RC2 Kernel.
I also have a nandroid backup of GB, but dont want to backup because i read online that the kernels are different and something to do
with the file system so you can brick your phone. Can i just restore the nandroid? or go back to stock? and how?
New to flashing, ROMS, Kernels etc. so i need help

You can restore the Nandroid without any problem. Everytime you change the ROM, Kernel will also be changed along with that. So after you restore the nandroid backup, your kernel will also be changed to Stock Kernel along with ROM. There wont be any problems.
Press THANKS if my answer is helpful.

If you are in Canada then I don't see how you will get ICS ota when LG Canada have said they won't release it there.
I doubt any release of ICS will be ota.
You'll possibly need to flash a downloaded rom to ICS anyway. Not sure if just changing regional settings will work but someone else can chime in on that one.

Are you sure, because i read online that ics changes the file system rendering the nandroid backup useless. And finally I don't need to flash a gingerbread kernel before right?, as nandroid restores my stock kernel.

Stock kernel is a gingerbread, one

Yes... The nandroid restore will restore the stock kernel as well. I have tried a few ICS Custom ROMs and restored my Nandroid backup and it restored the stock kernel.

One more question
Will the nandroid backup also restore the stock baseband and RIL?

Help - boot loop
I did the restore and it restored successfully, but when i reboot im in a boot loop and cant get past the white lg logo! HELP

FIXED
Changed to ext3 file system and it works now

Yes. Download a stock image from xda threads and flash it. You might have flash a new kernel if your coming from ics.
