Hi there,
I am new to xda and new to Android hacking.
What I wanna ask is, (I guess it's of most newbies concern as well), can we have a 100% backup of our system (stock ROM)? Obviously, it is important because:
If we perform an official (OTA) update to a new Android version. And we don't like it. It is possible to get back to the old original one which we are used to. (not everybody likes new things, and/or not every new thing is good)
If our phones are having some problems. And we have to give it back to the company for a fix. In most cases they will flash a new ROM for us. If we wanna keep using the old one (explained in #1), we have to keep a copy of it by ourselves.
If we want to try new custom ROMs, we may want to switch it back after trying.
Whenever we do any modifications, it's always better to keep a backup/roll-back point. In case anything goes wrong, we have a safeguard.
For the official warranty issue.
Yup I do see there are some official stock ROMs downloads for some particular phones. But those are not really a backup of our original ROMs. And it's always hard to verify if those downloads are the original official releases. And, if those downloads are 100% stock ROMs, this means some guys out there could make it, so what is the way to do so?
Or, how those mobile phone companies do it in their labs?
I have been doing researches on this topic for a few days. Some posts claim that their methods are "backup stock ROM" or "backup before rooting". But after digging into it, they requires rooting and/or flashing CWM. Here comes a few questions:
Questions
Rooting will in fact changes some files/data of the system. So backup after root is NOT getting the original stock ROM. Is it?
Is there a method to "un-root", so ALL the changes are TOTALLY reverted?
Installing/flashing things like CWM in phone requires rooting, which would make the ROM not original. Is there a way to extract the system backup from a computer externally?
In addition, I have found some related pieces. which could be useful to anyone viewing this post, and might be useful for you to solve this (my) question. :fingers-crossed:

ht tp://www .modaco .com/topic/351269-backup-original-rom/
In reply #5, user C3C0 raised a method of backing up the original stock ROM without root. But it seems he is flashing CWM and that method is only for ZTE Skate.
adb backup tool of Android SDK
At the first sight i came across this approach, I thought it is the official method to do whole system (ROM) backup (WOW - how nice!). But after studying for a few more posts, I think adb backup can only backup app+app_data, and possibly some system settings only. Am I correct? And also, adb backup is only for ICS (Android 4.0), isn't it?
adb backup usage: ht tp://forum.xda-developers .com/showthread.php?t=1420351
(But mentioned in the bottom of #1 the poster is having some issues on using adb backup. Perhaps there are some bugs and not reliable(?)
One more question on adb backup: Can it backup just one app+app_data, and restore just one app+app_data, without affecting other things? If yes, we don't need to root and don't need Titanium Backup (which requires root) for backup app+app_data. Isn't it?
** In case I have said anything or any terms wrongly in this thread, please DO correct me, for helping me and helping others.
P.S. i am using LG Optimus 3D.
Thanks a lot, wholeheartedly,

Backup phone before root
Hello all this is my first post here...woohoo!:fingers-crossed: This forum is amazing as to the amount of information available. I just wish that in looking for what I need to do I did not need to look in so many places. I feel that if I want to root my T-Mobile GS3 that all the information should be in one subsection of the forum, but it is not that simple I guess....lol Anyway any help would be greatly appreciated.
I have a Samsung GS3 with T-Mobile that I want to root. Everyone says to back up the phone before you do it but I am not really seeing how to make a backup before I start. It appears that most of the guides to root just say to backup without telling you how to fo it. Another thing (correct me if I am wrong) I see the nandroid backup that I think is a backup of the phone however it seems to be done after you make changes to the phone and I thought the backup was supposed to be done before you do anything. Is it that there is not a way to make a complete backup with an unrooted phone?
My question is basically the same as the OP here. I have been reading and reading and reading posts here in the forum. There is much information here and much of it is duplicated with slight variances in some of the duplicates. I am not certain as to which rooting method I should use. There seem to be so many choices. As a new person to this forum I will say that you can find just about everything about any phone which is awesome. The hard thing is sifting through the many options to pick one to use for your issue.
I do see that Mr. Robinson has a thread with backups of the original roms. The only thing is that they are default roms that are like an out of the box phone and not my phone with my apps and my settings. That is what I want to backup...My phone with my settings and my apps.
:good: Thank you in advance for any one that can shed some light on this for me and the OP'er

Hi ya,
It's so nice that you are having the same concern as I do.
As far as i know, the approaches of rooting differ from phones to phones. So we may have to find our own specific rooting method in the phone model sub-forums. It won't be hard for your popular S3
I would like to have a look at that Mr. Robinson's thread. If he can backup the stock ROM, those app+app_data wont a big issue (i guess).
cheers,

Hi midnight, welcome to a new and exciting world of Android and trying new things. First, let me assure you, what you want is NOT something new. People have been doing this type of thing for years. That is flashing and testing roms. As you will learn, it actually becomes quite addictive. We call those folks that get addicted to flashing: Flashaholics or crackflashers, lol
First let me talk about "root". This process consists of unlocking a lower level of the Android system known as the bootloader. Unlocking the bootloader of your device allows you to flash a custom recovery, flashing a custom recovery allows you to flash the Superuser binary and Superuser.apk, This is what allows you to use apps that require "root". The bootloader is not an OS file. So when you are unlocking your bootloader you are not modifying your stock rom. Only when you have flashed the Superuser package have you modified your stock rom. And even that isn't really modifying anything. When you flash the Superuser package, it adds two files to your rom at certain locations of the file system. It adds the Superuser.apk file to system/app and it adds the SU binary to system/bin. Basically you CAN have a totally S-OFF (unlocked) bootloader and still have an entirely stock rom if you want. But the real benifit is flashing a custom recovery like ClockworkMod Recovery and then flash the superuser package.
As far as extracting the stock system, you should try giving adb a go. Do it right now if you like. Ensure you have the android sdk installed and properly set up on your computer and your computer can recognize your phone. Ensure your phone is in debugging mode, connect your phone to your computer, open up a command window, and run this command:
Code:
adb pull \
This command will pull everything off your phone except for data which is where your market or Google Play apps are stored.
Beyond XDA there are aso more resources to learn from. For example, http://www.android.com is a good place to start, and to learn more about adb check out http://developer.android.com/tools/help/adb.html
If you need to learn how to setup the sdk here is the place to learn how: http://developer.android.com/sdk/index.html
I'm sure others will add to this as well which is the good thing about this community.
Welcome to XDA, I hope you have fun learning, and maybe share back someday things you learn along the way.

Hi Wildstang,
Thanks very much for your warm welcome and very informative reply. So are you a Flashaholics or Crackflashers yet?
As I am a newbie, please forgive me if I am asking dumb questions.
As far as I understand,
The steps of root is
1. Unlock the bootloader
2. Flash Superuser binary & Superuser.apk
** does "flash a custom recovery" means "flash Superuser binary & Superuser.apk"?
"Flash Superuser binary & Superuser.apk" is just "add SU binary to system/bin" and "add Superuser.apk to system/app". Then why not just copy them into place?
I just found on the web that "flashing" means replacing the OS of the phone with a new ROM. Would that still keeping the stock ROM?
To have a backup of the original stock ROM, can I
1. Unlock the bootloader
2. Flash Superuser binary & Superuser.apk
3. Perform the backup
And later, after I have flashed a new ROM, or whatever I do, as long as I didn't brick it, when I want to rollback my phone to its original, I can
1. Restore the backup
2. Delete "SU binary in system/bin" and "Superuser.apk in system/app"
3. re-lock the bootloader
Is this correct?
I don't mean to challenge you. But does adb pull \ really backup the system, or just all the files?
Thanks very much again!

Hey midnite_,
I am a newbie too and have a lot of blank spots in my understanding of what we can do with android. I also came here with same question. I found how to root, this isn't a secret. Like you, I want to know how do I fix it if I break it.
So, with regards to your questions.
1. Unlock the bootloader
Not clear on this one, as not every tutorial even mentions this part. My feeling is that this might be specific to some phones, like HTC.
2. Flash Custom Recovery (such as AmonRa, CWR, TWRP...)
Recovery is an intermediate stage of phone booting process after bootloader but before OS.
It is there to allow OTA (Over the air) updates. During those, the OS is halted and replaced with a newer one.
What this means for us is that the recovery is capable of replacing OS (ROM - are these terms interchangeable?).
Recovery is the same as hidden partition on windows, that is sometimes present on a PC. It has a limited interface.
It can replace one OS image with another. It probably checks the checksum and creates the new one after the update. It is probably the gatekeeper.
Stock recovery will not replace OS with an image from SD card or from PC through USB. Only OTA.
This is the reason for flashing the custom (hacked) recovery on.
Custom recovery is made to allow additional options, such as allowing image sources such as PC or SD card, and also a ROM backup (write OS image to PC).
3. Flash update file using "upgrade from SD card" function of custom recovery now in place.
In this step, the Superuser.apk and bin files are placed. Stock recovery will not let us do that.
Also, I think the reason we can't just use ADB to "copy" superuser package to phone is because the system is either running or exists as an image (compressed?), and is probably protective of its modification. (So, likely the superuser package also replaces the checksum that the OS uses to check if it has been compromised?) Yes, this modifies your rom.
I assume that unrooting could be done after this by updating again with a file that removes superuser package and that would make your rom stock again.
4 OR flash custom ROM, which usually includes superuser package. Of course using custom rom means you no longer have stock rom.
To have a backup of original ROM, you would :
1 Unlock bootloader,
2 Flash (install) custom recovery
3 superuser doesn't matter here
4 Use custom recovery function to back up your stock ROM.
I want to know the answers to the rest of your questions as well as some clarifications to mine.
Personally, I am looking for a way to backup the stock recovery as well.
I know there are some people asking about this. The procedure appears to be as follows:
(pieced together so don't take it as a tutorial)
1 Unlock bootloader (again, unclear on this. Also some mention S-OFF and others don't)
2 With USB debugging allowed (meaning connect as device requiring a driver), Connect to a PC with ABD, and a driver installed.
3 From ADB, issue a command "adb boot recoveryimage.name" instead of the usual "adb flash recoveryimage.name".
This will make the phone boot into a custom recovery image that is residing on PC, without first writing it to the phone.
4 Unclear how, but make that custom recovery now being live to back up stock rom to pc.
5 Unclear how, but make that custom recovery now being live to flash either root or custom rom to the phone.
6 Disconnect, reboot the phone. Once in OS, use root privileges to mount recovery partition ? (this makes it visible as drive)
7 Don't know how, but use root privileges to back up now visible stock recovery partition to PC as image.
( This should give you two out of three original parts.)
Keep in mind that even if my peace-by-peace "know-how" ever works, there is at least one clearly faulty step:
The back up of the original state of the boot loader has been never made. I do not know if it is easily can be toggled back and forth from lock to unlock and back without leaving any trace. Also, like yourself, I probably don't quite understand what am I talking about, but I have tried to make as much sense of what I have read here and there.
This is my first smart phone, and my experience with linux is limited to building a minecraft server on MineOS, which was pre-made so that not much was required to make it run. I have "mounted" a partition for the first time last week, trying to break Win7recovery, booting it with Knoppix. This is why I think this is probably will come in play here too, as the recovery partition on W7 was hidden. Until then I didn't understand what mounting means, as windows always does it for you. So, take everything I say with a bunch of salt.
Please, let me know too, if you find out more. I want to flash the hell out of my Prism, but I want to be smart about it.

Hi Descent2,
Yes i am still around but i am busy with other stuffs at this moment. Thanks very much for your reply. You have studied a lot and you really did good summarisations. Very informative and I learnt a lot from it. Hope some of the masters or experienced ones would come by and bring us out of the mist

Thanks mf2112. But those resources are seem only for GS3. And it seems it is not teaching us to backup our stock ROMs, it provides stock ROMs for us to download instead. Is there a general way to backup our stock ROMs?

You must unlock your bootloader then flash a custom recovery. You will then use that custom recovery to make a backup of your rom. That backup will be stored on your sd card.
Now, I have tried to help you and so have a couple other folks. You expect us to just give you answers step by step. I am sorry but this is simply not how XDA works. XDA is set up in a way which makes it for any users to find quickly what they want to know. Use the search feature on the site and you will find many answers. I tell you to go do your own research now and be proud of what you learn on your own. And if you cannot, please do not try to modify your phone further, you may just brick it if you aren't careful.

I put in the GS3 links since the OP was using that phone. Every phone will be different so I don't think a general way or guide would be practical.

Hello! So this should be an interesting first post. First, a little background:
I'm relatively new to this, and I've been trying to root my NEC Terrain for a little while now. I've followed the instructions on numerous pages in order to understand how to do things. And now I have been able to rip any partition from the phone. I've looked through everything I could in both the boot and recovery partitions but I haven't found anything I can use (I also explored /system but there doesn't seem to be anything in there either). Also, I tried to do everything on this page: http://forum.xda-developers.com/showthread.php?t=2337642 but I can't get SuperSU or TiBu to work. (As an aside, if anybody can point me in the right direction for the most recent su binary, that would be awesome). SuperSU wants to update the binary but fails. I would assume it's because it tries to install it directly into /system/bin, which isn't writable. If I could make it install it into /data/sbin, it might work, but that's off topic right now.
I would like to explore more of the partitions to understand what they are and what they do (I can't seem to find much information about them anywhere). I'm hoping to find something in the code to give a hint as to how to get into the bootloader. So, I have things like "aboot", "firmware", "MM", and "GROW", among others. Is there any way to decode or decompile those images so I can see what coding goes into them? Am I going about this the wrong way?
Thanks in advance to anyone that can help!
Maybe this will help you
In this post by E:V:A you can find some information about partitions and links to more!
I think latest SuperSU should be with latest SU binary (I can be wrong about this), so you could download "CWM / TWRP / MobileODIN installable ZIP" from this post and take one from "x86" folder.
Good luck.
Thanks for the links! Some of these may be very helpful. However, the su binary I got from that link was much older than the other most recent I had. It's a version 2.0 and they're up to at least 3.2 (I'll check the link again to see if I missed something). Also, for these phones, if anybody is wondering, they are ARM, not x86.
There seems to be only one direction I can go with this: Find an exploit that can run at boot that will interrupt it at the right time and allow editing of the /system partition. I can get a root shell with that script and a bind mount, but it's not enough to get anything else to work (ro.secure is still active, so there's no way to change it after the system is booted). Root is granted to root, and that's all. Any app requesting root does not get it.
The guys on that other thread said they got SuperSU and TiBu to work, but they provided very limited information and I can't seem to make them work. I wonder though, if that would matter as long as ro.secure is still enabled.
Found my old phone from high school. Turned it on and looks like I never factory reset it, and I would love to see all of the photos and messages I left behind, however I can not for the life of me remember the pin I used. Browsed around and tried to delete the gesture.key using ADB but permission is denied, and I wasn't able to find a custom recovery tool for this specific phone either. Anyone have any possible solutions? Thank you

If you cannot remember the PIN, you're most likely going to have to factory reset. There is no way around this that I know of, unfortunately.
you can just dump the whole userdata partition off flash memory in EDL mode, loop mount partition image from linux and modify it's content (like deleting locksettings.db)

1: can I just take the locksettings.db and somehow retrieve my pin from it instead of modifying and dumping?
2: if I do end up having to dump, will the environment be the same (IE logged in apps, id like to see my message history in apps that are there)
Thanks so much, and sorry for disturbing.

you need a firehose programmer matching your SoC and OEM. the tool comes with collection (loaders) for quite few devices, just give it a try.
1. might be possible with password.key
2. yes by just deleting locksettings.db nothing is changed
