Hello
I'm relatively new to Android an have never done any rooting or flashing custom ROMs. I'm looking for something where I can fully back up my device with the system so in case something goes wrong I still have my original ROM. When I searched for ways to backup Android I found lots of ways where you can backup your media but none where the actual OS is missing. All I want to prevent is basically ending up with no OS at all, how can I make sure.
Samsung Galaxy Tab S 8.4 SM-T700, Touchwiz, unrooted
Well if anything does go wrong you can download your firmware for your device and flash it with Odin on your PC but putting your tab s into download mode. Also to backup your ROM as it is, you would have to install twrp for your device. To find out how search it on google on how to install it on your device with the right model of your device. After you installed twrp, boot into twrp recovery and hit backup and check each box you would like backup. Then slide the slider and it should backup everything. I can tell you how to install twrp recovery and I'm not sure if it requires root. Hope this helps. And the downloadable Roms are on sammobile

Sorry for the noob question, what are the recovery roms for? Wouldn't you just need a stock to revert to if you messed up the phone royally? Also, where can you find them? I haven't seen the aman-ra anywhere, though people regularly refer to it.
Also, do all of the ROMs listed on the wiki work with 1.47? It doesn't mention the version.

A recovery ROM is what you use to manage full ROMs, you can backup, restore, wipe, mount as USB, all outside of the ROM loaded. These functionalities aren't available from within the system itself.
It's kind of like an advanced BIOS. You can't make a full backup of Windows XP while your IN Windows XP. (ASFAIK)
Edit : Amons recovery is included in all the full root method tutorials. It's called recovery.img
So, the recovery is more of a utility than just a backup. Usually you flash what is called the recovery partition with a recovery image. Once you do that, you don't need a computer to get into recovery. Anyway, the recovery does alia you to do a backup and restore, but it is actually the utility that you flash roms with. It also let's you wipe cache and stuff which is critical to flashing your own Rom.
You would use recovery to restore, instead of flashing stock, because it would return your phone to the exact state it was in when you did the backup. You don't lose any settings or apps or anything.
When you root via toast pt 2 you wind up flashing amon recovery. There is also a thread in the dev section with a different version I think, just search amon.
And most roms on the wiki have the newest ota integrated in the Rom, but you should always consult the first post in the roms thread to see more about that.
hi xda
first post, 2 week old first android phone (galaxy s GT-I9000).
I've just rooted my phone using super one click. im always reading that i HAVE to perform a nandroid backup before i do ANYTHING after i've rooted my device.
When i google "how to nandroid", i just get "get into recovery mode, select 'nandroid backup'.
But there isn't any back up options, only the standard 4 options: reboot, apply update, wipe data/facotry reset and wipe cache.
2 questions:
1) what must i do after rooting to make the nandroid option available? Surely doing THAT is doing something, therefore putting my phone at risk?
and thus,
2) what can i exactly do after rooting, before performing a nandroid? one click lag fix? normal use? installing a ROM? My understanding is that the nandroid backup is in case installing a ROM goes wrong, but then again a lot of the 'how tos' say you should instal clockworkmod, or rom manager before making a nandroid.
Please shed light.

You need a custom recovery like cwm installed to do a backup and for flashing ROMs. Whether you choose to do so is up to you, but there are advantages to being rooted either way i.e Apps that require root access to work.
thanks for your reply - please clear something up for me...
Everything i read says do a nandroid before you flash anything, but then it sounds like you have to flash a recovery ROM in order to do a nandroid?
Please let me know
1) how to install cwm recovery ROM and
2) what can go wrong? (since i'm doing this before making a nandroid)
3) can i install the recovery ROM before i root?
okay
at the moment i've got this far:
rooted? check. (super1click)
rom manager installed? check.
problem:
when i click flash clockworkrecovery ROM in ROM manager, it prompts me to choose my model (Galaxy I9000 International). Then it prompts me to allow poweruser functions, which i do. Then it saus something to the effect of "ClockworkRecovery ROM has been downloaded!"
note: not flashed, or installed, downloaded.
That finished the 'flashing' process. Now, if i select back up, it boots into recovery mode, but its still running the stock android recovery (2e), without any option to perform a nandroid backup!
How the hell do i do this? aargh.
help would be apprciated.
Go back into Rom Manager and again select install CWM and then backup current ROM. (sometimes it just needs doing again).
While you are using a stock ROM the stock Recovery will reassert itself on every boot, so having to flash CWM multiple times is not uncommon. Of course, this behaviour stops if you flash a custom ROM.
I've flashed it 3 times.. still no cwm recovery Rom... how many timed should I do this before trying something else, and what is that something else?
Just flashed another 3 times. Still nothing... please help!
THIS is the correct section for your device. I'm sure you'll find the answers you need there.
Good luck.
Hello everybody,
I got a new s4 mini from Poland, and I live in ISRAEL, some guy here opened the region locked problem somehow, when rooted the phone he triggered the knox 0X1.
today I installed CM10.2 on my phone (not with ClockworkMod but with Team Win Recovery Project), and I would like to go back to the original stock rom.
I think I've used backup, but after it I pressed on factory reset, and I can't find a way to restore it, does anyone know how? and if not, how can I install the stock rom again without triggering the region locking thing?
thank you for you help.

At TWRP there's menu for restore, if you see nothing under restore, that means no backups were made. Factory reset has nothing to do with restore a nandroid backup. It simply restore to the 'original state' of the current installed ROM.
If you already triggered KNOX, there's no going back. I have no idea what the 'guy' did, but rooting has nothing to do with region lock.
If you want stock ROM, you need to download the ROM file for you phone and use ODIN to flash it back.

So no backup. I mentioned the Knox because I'm afraid to downgrade back to jelly bean4.2.2. Anyway, I can't find ROM stock file for Israel for i9195. Can I use something else? Thank you for you help.
Hi,
I have to install CM11 on three different smartphones, being Galaxy SII, S4 mini and another one.
I wish to ask how can I create a firmware backup of default factory setting phone so that if I wish to go back to original device I can restore the Samsung Firmware.
I have never done it though I am trying to document myself on the Internet.
What are the tools and the steps in creating a firmware backup? Obviously, I will factory reset the device before doing so.
Thank you

you could do the following
install twrp recovery
then select the backup option and follow the screen guide
if you one day wanna restore it, use the restore option
There are many tutorials to install recovery in the dev thread.
As mentionned above, TWRP is highly recommended.
Thing done, you can make backup of any patition you want.

I tried flashing a rom into my phone.
It didn't work and I wanted to restore from the backup I made from TWRP.
I restored my original OS from TWRP, and it's booting up to it, but once it gets to my lockscreen and after a minute or so, it reboots. This happens every single time. Does anyone have any ideas of what to do?
Something is false with backup I would say.
Flash stock firmware, root it again and then play with custom rom again.
Since, I'm relatively new at flashing. I just want to make sure I am doing this correct.
So I can get the stock firmware from this site:
lgg3root (turns out I can't post the url yet since I'm a new user)
Then I would have to choose the ADB sideload option in TWRP since there would be no other way for me to flash it correct?
Also would flashing the stock firmware delete everything in my internal storage?
