[Q] When recovering/reverting back to a nandroid, necessary to wipe first? - Android Q&A, Help & Troubleshooting

If I need to restore a nandroid do I need to wipe/factory reset everything prior as instructed when installing new roms?
Or if I need to restore a nandroid can I just boot into cwm, go to restore nandroid, restore and go?
Is there a difference?

Just restore the nandroid. Recovery first formats all partitions and then copies the backup images. It's all automatic, so it's redundant if you format manually first and then restore.

Wipe first the backup nandroid

shall i wipe first then backup nandroid , or vice versa , i am about to install custom rom and want to know this before i start.
i am on official htc firmware at the moment
if you wipe first and then do the backup you have a backup of your wiped phone. you make the backup at a point that you want to be able to restore. you can do a wipe everytime, so why would you want to do a backup of a fresh wiped phone?

[Q] Nandroid Backup

Q1:
I have root + CWM Recovery from CF-root.
Im on stock TouchWiz 5.0 and all stock from Samsung. Only thing I've done is the CF-Root.
If i make a nandroid backup now in CWM recovery before I install a custom rom, will I then later, if I want to go back to the stock Touchwiz and firmware, CSC etc. Can i just restore the backup?
Or do I still need to flash stock firmware and that through Odin?
Q2:
If i make the backup to the Internal SD Card, will using the Wipe data/factory reset in CWM recovery, remove my backup?
Q3:
How much space does a backup take?

1. Yes you must restore Nanbackup from the same Rom you made the Backup with.
2. I think yes, so make Nanbackup in ExtSd, I think is factory default in ExtSd, at least mine does it...
3. About 2Gb

Installing nandroid

I see nandroid images how do I reinstall in case of a failure
Sent from my SAMSUNG-SGH-I717 using xda premium
Nandroid images are restored from within your recovery...
You would boot to the recovery, data wipe, cache wipe, and dalvik cache wipe, then restore the nandroid backup from the restore sub-menu of the recovery...
Note: you must ensure that you have the same recovery that created the nandroid image...I.E. CWM for those images, or TWRP for their respective image.
They are "NOT" compatible..
It's toooo easy....g

[Q] Does Nandroid backup restore modem?

Hi everyone,Before Installing WanamLite V6.0 I made a Nandroid backup. Now I want to revert to stock ROM which is the Nandroid backup I made,but wanted to know,does Nandroid Backup Also Restore MODEM? Cause I don't want modem to be restored.
Thanks in advance! :fingers-crossed:
A standard Nandroid does not.
CWM does not backup or restore the modem.
Not too sure about other recoveries though....
I'm using Official CWM 6.0.3.1! And what about folders on the internal SDCard? Cause WanamLiteV6 is Android 4.2.2 and messed up Internal SDCard with emulated/0 folder...
you should be ok.
sdcard/0 might still exist after you've restored but can be deleted....
Will try to restore then,will let you know
If you face problems going back to your nandroid try using philz recovery and completely wiping the phone before you restore. It should get rid of everything.

CWM noob question

If I restore back up I made with CWM with it will it flash Rom too?
I mean let's say I have stock Samsung Rom then I flash the cm back will it be like flashing new cm Rom but with my apps and settings already?
Restoring android backup take your phone exactly at the moment the backup was done. Rom, kernel, apps, data, everything.

A Nandroid backup takes images of your partitions.
If you want to restore a previously made Nandroid backup, enter Recovery Mode select Restore. Everything should go back to how it was when you made the backup.
If you choose the ‘Advanced Restore’ option, you can select which component of the backup to restore – like the boot, system, data or cache.
Downloaded apps, apps and OS settings, contacts, messages are backed up in data (/data)
boot has the initrd.gz and zImage.
system has the system files (/system)
cache has the cache (/cache).
SD-ext has the ext partition
