When a thread's instruction to install a custom ROM or a very complicated hack/plugin and says do a "complete wipe first" or "make a nandroid". What exactly do they mean?
Please correct me if I'm wrong--
Complete Wipe is when we delete the following prior to flashing something:
/data
/cache
/system
/dalvik cache
And making a nandroid is making a backup of your complete setup via CWM's "Backup and Restore" option, right?
Can someone please clarify this?
LOL
You're not alone, lady
I was seeing so many nandroid and have no clue what it is but base on my own definition, it is Nook Android, meaning the stock ROM, meaning, make a backup of the original stock ROM.
That's how I understand.
Complete wipe? I only wipe /cache and /Davik cache and factory reset (sometimes)
That's all.
Nandroid is a complete 1:1 backup of whatever rom, apps, and data that are on your nook.

A complete backup would include /data,/system,/cache, and /dalvic cache. Sometimes folks also do a factory reset
A nandroid backup is done using clockwork to backup your current Rom as well as your files and settings so you can restore to a working system if something goes wrong.

Noob here. It doesn't "seem" like Acer Recovery is actually making backups of my ROMs. I'm really missing something either in terminology or execution and I'd like to understand what it is.
I don't know how to explain it other than to relate exactly what happened
I purchased one A500, but had to return it. I kept the backups taken with Acer Recovery, all Build A500_4.010.13_COM_GEN2
Got a new tab with Build Acer_A500_4.010.07_COM_GEN2
I immediately did a full backup:
Root (Iconiaroot 1.3)
Acer Recovery Installer
select "ClockworkMod Recovery rev1.3.4 by thor2002ro"
click "Install Recovery Image"
click "Yes" when asked to backup the current image!!!
Reboot into CW recovery.
Create a full backup: "backup and restore" -> "Full Backup"
The backup proceeded normally.
Rather than re-installing everything, I restored one of the backups from the old tab with Build A500_4.010.13_COM_GEN2
Backup installed fine, but instead of Build A500_4.010.13_COM_GEN2, I had Acer_A500_4.010.07_COM_GEN2, the same as the new tab.
I thought that was odd and I still don't know why it happened, but as I had just made a fresh new backup, I let the new tab go through the OTA updates to Build A500_4.010.13_COM_GEN2
Got everything working OK and decided to restore my new stock backup and make fresh incrementals of all the OTA updates.
Restored the original backup and now my original backup shows Build A500_4.010.13_COM_GEN2 instead of the original Build Acer_A500_4.010.07_COM_GEN2.
From these two instances, it doesn't "seem" like Acer Recovery is actually backing up or restoring the original ROM.
What is it that I'm either missing or don't understand about this process?
Thanks
If I understand the process, Acer Recovery will make backups of your recovery image. CWM does a full backup of ROM/kernel.
So, I'm not sure if I understand where you are restoring from.
If you restore through the Acer Recovery Installer, you should be just getting the old recovery image.
If you restore through the CWM menus after botting into recovery, then you are doing a full restore.
First.. it's not Acer recovery installer that's giving you the issue. The backup and restore are functions of clockworkmod.
The problem was that your flexrom did not get restored due to a bug that I demonstrated on thor's clockworkmod thread.
When doing a restore that restores data.img, it will also attempt to restore .android_secure.img and will fail, skipping flexrom which is supposed to follow. I bet you don't ever see the "Restore Successful" message after a full restore.
You need to either delete .android_secure.img from your backup set or restore flexrom separately.

PS. Clockworkmod does not backup anything from /data/media

So how to do a full backup of the image and restore if not from cwm.

Thanks Euclid,
Sorry about the confusion in the thread title. I thought Acer Recovery Installer had several functions: backup and restore recovery images and load CWM recovery to do the actual backup and recovery. Since I thought it did both, I assumed it was O.K. to use Acer Recovery Installer generically.
I did another restore to check what was done:
Fixing a500 Boot/recovery Checksums...
Running itsmagic
Done
Checking MD5 sums...
Erasing boot before restore
Restoring Boot Image
Restoring System
Restoring Data
Done
Screen refreshed to "Reboot Now".
As you said no "Restore Complete" message.
I wonder how many people including myself, assumed that the restore had completed successfully when they got the "done" message?
Both fixes worked well. I hope this helps someone else.
Below is the text from within CWM Recovery when .android_secure.img was deleted from the backup folder and a restore was run:
Fixing a500 Boot/recovery Checksums...
Running itsmagic
Done!
Checking MD5 sums...
Erasing boot before restore
Restoring Boot Image
Restoring System
Restoring Data
.android_secure.img not found, Skipping restore of /sdcard/.android_secure.
Restoring cache
Restoring flextrom
Restore Complete!
Restored my original stock ROM. So nice of it to ask me to update to a newer version immediately after the restore!
I did have one problem. I tried deleting .android_secure.img while rooted, using ES File Explorer with the Root Explorer and Mount File System options selected. I could never see the file on my external SD in the clockworkmod/backup
folder, so I pulled the card and manuall deleted it from my PC. I'm curios as to why this happened, but it didn't affect the result.
It was just as easy using backup and restore/advanced restore/your restore folder/ - Restore flexrom from within CWM Recovery.
I've read hundreds of post, in I don't know how many threads, sticky's included and never saw the advice about deleting .android_secure.img, manually restoring flexrom or even checking to make sure that you got "Restore Complete" I wish these things were part of an updated guide.
Lesson learned,
Thanks again
Just wondering, is there anyone working on a new recovery which will complete backups and restores without additional deletions, etc.?
bug was in thors post
The bug was mentioned.but I don't think there was much discussion about it.I don't think Thor acknowledged or tried ti fix.
With that said I could be incorrect. I however even with the bug think its a awesome tool.don't. Consider this as complaint.
Its like on page 3 or 4of the Thor recovery thread if im not mistaken

Yeah we need something reliable when restoring from backup. I tried once, cwm sees it but can't do the restore so I gave up even though I had all my apps backed up so did all one by one.

Hi Everyone,
I have an P5110 running stock Samsung 4.04 ICS firmware it's rooted and has cwm touch recovery installed and titanium backup pro (root) installed.
My question is this how do i verify a Nanodroid backup ?
I have read it checks the backups before a restore.
However, When running version 5.xx of CWM recovery it failed twice to restore data and since i couldn't i find a way to check the data before i restored it.
Data was overwritten, however cwm reported a fail to write to data, and sure enough no data had been written but /data had been formatted.
Is their a way to verify a backup before i choose to restore it ?
i am now using ClockworkMod-Recovery_6.0.1.0
thanks
Col

,,,You have to backup EFS once (via non-buggy twrp) and keep it stored on mobile and PC
... For ROMs..You just BACKUP system data boot
And restore them
... when shifting () different builds marshmallow to nougat... nougat 7.0 to 7.1 or whatever.. you need to INSTALL (not backup or restore) the CORRESPONDING vendor
That's it
Guys, do TWRP backups work well? I still have the stock and I made a backup of the rom with TWRP, if you install a custom and if you want to go back to the stock, just format data and do the wipes cache date and system, and install the backup?
