This is absolutely unfathomable.
I find it nearly improbable that in order to create a FULL backup of a phone, you must root it, first.
With the possibility existing that an attempt to do exactly that, may well brick it.
And then we don't need a backup. We need a new phone. :silly:
But, an actual backup would have us able to re-start and try again (and again, and again, ad infinitum).
In hand, one bricked handset (ZTE N9132, and not actually via failed rooting). Let's call it TARGET.
And, luckily, one un-bricked handset of same (ain't eBay great). Let's call it SOURCE. They are running under version 5.1.1
Yes, I know, swap the SIM, change IMEI with carrier, back in business ... er, SOURCE broken glass and just ugly condition notwithstanding. BUT, as a learning experience for me, and a wish-I-had-done-that re-do for others with a similar brick, here's my desire.
I've been all over the web and just when something sounds promising you read, "this next step requires a rooted phone" .
So, here is a working SOURCE phone. stock. just as received from vendor. not setup. factory reset. no SIM.
I want to create a COPY/BACKUP/ROM (correct my wording, please) of this SOURCE phone. Wait... format requirement coming.
Then need to PUSH/SIDELOAD/UPDATE that SOURCE image onto TARGET, and we must note for record that TARGET only boots in recovery mode (i.e., not recognized by PC). That pretty much leaves the "from SDcard" option.
ADB, fastboot, FTM, something else? ... any and all NOT requiring "root".
Because both phones are wiped/reset, user data, settings, etc. are immaterial.
We would be only concerned with creating the minimum image from SOURCE possible to allow TARGET to "snap out of it".
How about it guys ?
Can this actually be done WITHOUT ROOT?
Thanks in Advance
Hi !
I wish you would post a little bit less fancy because some of us aren`t native English speakers , like me ... anyway , let me tell you what I`ve understood so far
You have 2 devices which are the same (note that "same" doesn`t mean same brand but exactly same brand VARIANT as same brand may have multiple variants)
You want to transfer a nandroid backup from one to another directly using a PC when both connected to the same PC
First , that`s impossible
Second , even if would be , one of them isn`t recognized by PC due to "brick" status
So , disconnect them both , get a coffee , pull the backup from the working one , save it on the PC , keep on drinking coffee and find a way to un-brick the other device
When done ... hum ... well , if the bricked device gets back to life , no need to restore any backup , right ?
I understand what you want , you think that pushing a backup from a working device onto a bricked one may fix it , nope , it won`t work
How to unbrick your device , as I couldn`t find any support here on XDA for it , can be posted here https://forum.xda-developers.com/android/help
And to make a nandroid you don`t actually need root , you need an unlocked bootloader which allows you to flash a custom recovery which has this function
Here is an interesting tool
Good luck !

YES! That's exactly what I want.
And "IT WON'T WORK" is the part that blows my mind.
Exactly the situation when you restore a dorked device from a bad/failed upgrade via recent backup.
But, in this case, WHY doesn't that work?

New posting coming to /help
The process of writing the partitions is not just a simply copy /paste (it's above my understanding especially on Samsung devices...) connect to Odin and you'll see how many processes are used in
Follow that tutorial and also post there you're findings or concerns, I'm sure more skilled people will be able to offer help, Haraso camarad! ?

First of all, let me introduce myself. My name's Rafael and this is my 1st post in this forum. I hope humbly that you can to help me with the problem that I'll show you then:
Well. To begin, the issue is this... I am working with a telephone that's not mine. Somebody sent it to me to fix it, they said me that the phone doesn't download more apps because of "full memory". When I checked it, apparently it had the internal memory partitioned incorrectly, it said it was 16gb total storage with 7 GB available, but when I was installing some apps and went back to see the memory, it showed the Available Storage Memory with a large negative number, and it wasn't letting me install more apps. Some of the features of the phone are the following (according to MTK Droid Tools):
MTK6589 <---------(Actually it's MTK6571)
Model Name: Galaxy S5
Android Version: 4.4.4 <---------(Questionable)
Model Number: SM-G900H
Base Band: G900HXXU1ANCE
Then, to see if I could make some change, I decided to install a custom ROM, apparently for MTK6589 (at that time I didn't suspect about the horrible phone's falsehood). I wanted to see if this ROM brought the partition configured correctly. I tried to carry out the installation by the CWM Recovery from SD card. It turned out that the installation did not exceed 10% and it froze there. Then I removed the battery of the phone and inserted it again. When I try to turn it back on, it stays on the screen Mediatek. And from there, it does absolutely nothing more.
I've tried to flash back the backup that I made to the phone with MTK Droid Tools, both version 5 of SP Flash Tool as version 3, but I'm still not achieving positive results, always it throws me errors errors and more errors . I've searched all over the web, compatible ROMs for this phone, but apparently there is not anything. The only way in which (at least) it begins to flash from SPFT v5, is loading a ROM MTK6571; if not, it only throws errors. However, I've already tried, but it gave me error. It appears when the yellow bar that says Download Flash reaches 3%, and then it throws the error.
The only possible solution I see is to make a ROM (from the backup I made to the phone with MTK Droid Tools before to **** it up) installable from recovery (CWM) that is the only thing that works relatively well. And I have not reached that conclusion alone, but in bilateral agreement with an expert from another forum with who I have almost a month discussing the issue.
I really need help buddies. I am desperate because I'm a bit under pressure because I have almost a month with the phone without achieving the desired results. :crying:
Greetings and thanks in advance to any of you who want to help me.
PD: Sorry for my bad English if I committed mistakes.

Do NOT do this. None of them will work.
Your issue is that 99% of the time clones dont not have the software they claim and are never made by the company they claim they are. You could try porting a rom over that has the same chip but ill be honest. XDA doesnt really do anything with cheap knock off devices. Most people avoid them like the plague.
Sorry for my previous post..... I didn't read carefully. It's not s5 its clone....
Another way...

I was thinking about to take system.ubifs.tar and boot.img from the backup, to turn it into a bootable (installable) ROM from the recovery. Is it somehow possible?

Best advise is that you can try. Like I said we dont deal with clones at all really.
Worst thing that will happen is that it wont work and you learned a lesson about clone devices.
I have a Wacom Cintiq Companion Hybrid ( DTH-A1300L ) android version needs help in so many ways. I bought it because I really need one for one of my jobs, yet can't really afford the crazy overpriced insanity that is a new Wacom so the reason it was so cheap was "can't connect to the Play Store. I know, hella foolish, I thought I could fix it by rooting it, but this thing is like level 10 as there is so little info as no one wanted to touch them it seems. I did find one guy on this forum that at one point rooted I am fair to average at rooting and the understanding of all that surrounds it. I have happily and successfully rooted my phones and tablet but I am no pro and fairly good at having gaping invisible holes in my info or logic when it comes to things like this.
Most frustrating is this thing is stuck on android 4 . 1 . 1 for no good reason I can imagine. It has dev tools installed after factory data reset but no google apps. (It arrived factory data reset)
I tried the relevant framework and store and the delete the cache trick to no avail. It can not update and can not even get to the Play Store.
Sooo the bad news is; no Google apps. No updates offered and stuck on some weird what looks like not stock version of 4 .1 .1 Jellybean.
When I plug it into my PC via USB it does not even show up in device manager.
The good news is I rooted it. Checked with root checker (unfortunately for now its Kingroot)
1. I have no idea how to make a back up from here. (no USB connection to PC issue)
or
2. what rom will work as my device is not listed on any of them. It would be great to find the stock rom as I am afraid this things cool and weird cintiq mode, pen function like abilities may be disabled or rendered useless with just any android rom.
Is there anyway to somehow find the stock OS on my device through boot loader? A place to find my stock or like rom. A clever work around?
Thanks in advance. for any who take up the challenge and offer any help or thoughts.
Cheers
Anyone know
What clockwork or custom recovery should I use?

Excuse my noobness. Flashify looks good, I installed it, but don't I need some image from somewhere either the stock OS or a new one for it to work? Not sure how to get Gapps from there.
It did I think, find something, a "restore kernel" and "stock recovery" I am unsure did it find my stock kernel and recovery and or ROM and I should boot from that? ( again apologies a-lot of new info and its getting a bit swirly) In otherwords since my device is not listed any where and at this point any working Android version will do, I am wrong to try and reboot from this? These devices are supposed to come stock on 4.2.2, so I am hoping perhaps incorrectly it will go back to that? That would be ideal at this point.
So I can work again whatever works.
Also I a bit concerned about the "date" I posted from on one of these. I think I posted from the Wacom. Perhaps the problem in deeper than I thought as that is Linux time 0?
I think it self corrected but originally it said I posted on Jan 1 1970...
As for custom ROM, I probably wont be able to make my own custom ROM, even though I would love to take to the time to learn, for now I have too many art and work related deadlines.
I was hoping for one that already existed that would work with my device.
Perhaps I misunderstood something about how all this works? Also I do not have Unbuntu. I should as I support an open internet, but WINE really does not run the Adobe products I need for work so
I am stuck with Windows.

If you just want to be able to install apps from the playstore then this is a simple alternative
https://www.xda-developers.com/unshackle-your-device-from-the-google-play-store-with-apkupdater/
If your phone is rooted then flashify can flash zips like gapps without the need for a custom recovery. If you are serious about trying to make your own rom/recovery then use a virtualbox in windows. http://www.osboxes.org/ has plenty of prebuilt virtual linux machines that will run on windows
Regards
Sawdoctor
I appreciate all your help. I got the "google of every kind from Gapps on has stopped" is over, which was intense as it popped up every few seconds, I somehow got that to quit by reloading the proper one from the APK Pure app which was an odd work around but nothing else was working. Still have this unsettling bare bones screen and none of the stock apps as well as it being stuck in 4.1.1. This device was made for 4.2. and I assume it was on here at one point.
I wonder if that alone could cause hardware issues. I thought about taking out the battery, until I realized that thing is inaccessible as a thing can be without wrecking the industrial glues and taking the entire thing apart which sounds
like an accident waiting to happen and possible making things worse. I imagine that is last case scenario.
Like I said I would love to make my stock reload, at this point that would be great as this thing seems unstable and no trick makes the play store work or allow me to sign into the device with my google email.
I think you are saying to make my own recovery/ROM of my own device I need to do the virtual box thing. Correct? Or is that for writing your own custom ROM? I can try that; make my own recovery that is, as it is not on CWM or TWRPs supported devices list so I have no choice and all in all would prefer the thing to load as if it was fresh out of the box not this 4.1. One serious hiccup I have found trying to use my PC is my device is not recognized as a storage device or otherwise. Not sure if this is due to the weird settings of Cintiq mode or simply because the thing is in a very weird state of 4.1.1. So that may make making changes via computer impossible. I am not the type to give up. Thanks again Saw
Here also is a sum up I added to a the just basic question of Can you find the Stock from a recovery device. Basically is there any way to return a device to stock with no ROMs available to do so, as in extract if from the device itself.
Additional backstory if helpful.
"I have a Wacom Cintiq Hybrid running Android 4.1 that is ( now ) rooted..
This is a very bad thing. The Real Stock ROM has palm rejection and all the drivers to make it work as a tool. So stock is the ideal but it is clearly not stock as my device supposedly came in the
box running 4.2 and with software and drivers to make it work properly with the pen. This has nothing. No software and the smallest amount of apps possible. Worse this is no custom ROM its on ( I think) as it would be the worst one ever and it was not rooted on arrival. I have no idea what happened before I got it. I may have made the mistake of rooting it really as I found out to my dismay there is no ROM support. So back to square one. I bought it ( very cheap for one of these ) "stuck and unable to go to the play store" and I did not realize until I got it, on a version of Android it was not meant for. Wacom is totally and woefully unhelpful in every way. They seem to want to quietly put this device behind them at the expense literally of their customers."
My question current is really about better understanding something in this whole Root and Linux learning adventure I think I am totally confused about.
Basically if no custom ROM exist or your device is not listed on the supported list of devices in any recovery program....
OR as in my case you want desperately to get the thing back running on it's true stock what do you do?
Your rooted, but stuck.
So my main question is:
What is the best way to bring a device back to stock if there is no stock ROMs available and factory reset will not work?
On any device in this situation. Mostly I am hoping to have it explained in a way I can really finalize this confusing hole in my logic.
Like can a recovery program find it if it is still on the device somewhere and if not, why not?
Thanks in advance.

Hello & welcome to xda-assist,
If you rooted the device you changed the system /kernel in the process, if root is all you done you should be able to unroot by using the unroot option in your root management application, if you did further changes like deleting system apps and so on it gets more complex, the best and easiest way to get back to the original state would be a copy of the latest firmware.. If it doesn't exist you're somewhat out of luck, please refer to this link for further help & information..

Thanks for the reply. So no way to get the extract the original firmware? I don't wish to un-root. The device was set to a very sad state of affairs when I got it, unrooted, with something very unlike the stock firmware and factory date reset not helping at all. Persistently locked into a lower version of Android than it was not meant for and not running the drivers or software it would seem I need to make it function properly that came with the device.
Basically it lead to my curiosity of how one goes about extracting or mining the data that is stored somewhere on the device if all I did was root. Which is all I did.
It should still be there. Basically how do I get to it?
The link takes me back to the forums for help, however I found no help there after much searching before I asked here but thanks

Totally cool. It's a tough question.
The OG firmware thing is the toughest part to understand. Just wanted to make sure I was clear in my explanation and question.
HI there.
i read this :
Soft Brick
Soft brick is the state of android device due to some software problems like bootloops or device freezing at some point during boot. This may occur if some software problem occurred in the device mainly during OS upgrade or flashing something such as a custom ROM, camera mod or app in your custom recovery mode. A soft-bricked device is only half-dead. Because of this, your device is not booting anymore or is constantly crashing but can be recognised by a computer.
When your phone is soft brick, don't be panic. You can revive your Android device as long as it is only soft-bricked. The basic solution for this issue is flashing a clean and working version of Android to your device. While, during this process, you may need to restore a backup, flash a custom ROM or stock images to your device.
Hard Brick
Hard brick is the state of android device that occurs when your device is unbootable without a bootloop. A hard Brick device generally show little to no signs of life. If this happens, you had better to buy a new device since your device is showing you a black or grey screen at this point.
A phone get hard-bricked due to trying install ROM not made for the device or use ROM Manager incorrectly. Hard brick is more difficult to resolve and you may require an expert to give you professional advice. However you can recover from hard brick by using JTAG or send your Phone to JTAG service center to get it fixed, which means you no longer need to buy a new one.

Is it true that even hard bricked device can be high percent recoverable?
I own service and want to know the things good and be normally good. If i have to i will take loan to buy nessesary stuff to be successful.
Is that with JTAG true for tablets too? I have buyd from AliExpress Phone Box 2017 version but still havent used it.
If i have to be more specific. Have one client`s tablet here. It is recognised by Windows as MTK something and gone after seconds from device manager then recognised again and that...
history : it was virused and install OS to it was really needed. I shot in the dark and install it some OS for these parameters:
mt6582 1G+16G and flashed it successfull with SP Flash Tool but now the device does not boot and is half recogniseable in Device Manager. I did that because the device/'beauty' chinese tablet/ has no ID on the back side of it.
I hope this time someone to tell something good and usefull.
Thanks

history : it was virused and install OS to it was really needed. I shot in the dark and install it some OS for these parameters:
mt6582 1G+16G and flashed it successfull with SP Flash Tool but now the device does not boot and is half recogniseable in Device Manager. I did that because the device/'beauty' chinese tablet/ has no ID on the back side of it.
I hope this time someone to tell something good and usefull.
Thanks

Yes, it is "possible" to recover hard bricked devices with a JTAG but there are no guarantees it will work and no way to guarantee each customer that there device will be fixed.
As for the MTK device you are trying to repair, you can't just flash a firmware from another mt6582 device, there is quite a bit more involved than just the same CPU. Firmware from another device must be ported to work with the other hardware on the device.
You need to identify more about the device than just it's CPU if you want to find a firmware that will work without modifications.

If that's the device after you flashed it, it seems to be booting fine. Is it having issues where some features and functions aren't working correctly?

Unfortunately this is the device before flash.
It`s labeled as pc703 in the seller site/bulgarian not China/
The back cover of the device is

Can you give me a link to the seller site?
Usually these cheap off branded Chinese tablets are almost impossible to identify properly because the hardware varies so much even among separate devices with the same model number. It is like this because there is no actual "manufacturer", these devices are pieced together with cheap discounted components that were bought in bulk and they use whatever they can get to work, even if it involves using completely different components. This makes it virtually impossible to say exactly which firmware you need.
When a device is bricked and the device is one of these cheap devices that can't be identified properly and has no available stock firmware or stock source code and has no support from the manufacturer, typically, the only solution is to just try different firmwares and hope one works or piece together your own firmware with pieces of others that might compatible.
You'd have to have a lot of time and android development skills to make your own firmware.
You've got a difficult road ahead, I'd suggest they replace the device because the cost of repair will be more than the device costs.
When you flashed the device with SP Flashtool, did you happen to pull anything important from the device or did you by chance make a backup of some sort before you flashed it?

Man usually understand his mistakes after he did it.
Maybe I will never take again unknown tablet for service. The problem is that the customers are waiting and I am tired of buy customers devices either second hand or new.
The site should be 4sales.BG
That said the woman.
The 'cool' is that I find there version not with 1g+16g
Good night.
In simple words, Soft brick is messing a little with your Android from which you can recover easily.
Hard Brick is like screwing up your device completely, yes, you can recover, but it needs lots of technical process.

Technical or not that`s not bad. Just want to have the nessesary tools if they are not too expensive. I just wont desolder very very small smd resistances and transistors
If someone can help in my chinese tablet case i will be a little more not unhappy.
Hi there!!!
may be this is an academy question, but in my case it is really true:
I have got 2 identical android device, the first is working 100%, the other it's bricked, coz i flashed on it a wrong rom.
Unfortunelly it's old and the producer is now not available..... in other way I may not restore with an original rom, coz I dont have got it.
Is there any possibility to perform a full clone copy from the working device?
I'm referring to a VR-TEK AVR1-WTK170000B, it's an ancient VR all-in-one visor, but the situation may be the follow also for any smarthphone device when the original rom is unavailable.
I have just try with "adb backup -all" but the result (of course)== 0
I would like to try in loading (without install if possible) a "general recovery image" like f.e. TWRP, but more "android generich".
The broken device btw still respond to both adb and fastboot command, but I have no idea to obtain the result.
Please apologize for my terrible english and for my inexperienced, many term I have utilized I know are NOT technically precise.
At least I hope btw that the concept was clear.
Is this an "impossible mission", or maybe I have any chances?
Thanks for read me, and greatings to ALL.
