Hi Friends
I have got a One plus 7 phone having 128GB Internal memory from a friend who has accidentally Reset it causing loss of photos.
I want to access phone's internal memory fully to recover data.
I have asked him to root it and bring to me for recovery. He has taken it to some expert who has enabled Developer mode and Rooted phone.
So when I check Debugging mode is enabled , Developer options are selected and phone is rooted.
However Still internal memory is not accessible. I have checked with person who has done rooting.
He said he has done System rooting and storage Rooting also needed to fully access internal memory. I tried Kingosoft Rooting software which failed to Root the phone.
Can someone pls. let me know how to make Storage Rooting ?
Thanks.
If a Factory Reset was applied then all user-data got wiped, means they no longer are accesssible by you: it would need forensic tools to recover them.
To create a bitwise copy of the storage space where the wiped data physically still are located - typically in partition /data - phone's Android must be rooted and accessible by ADB.
BTW: A phone's Android is rooted when in Android OS a binary called su is present and executable.

jwoegerbauer​Thanks for replying. I want to recover data and whatever software needed I will buy, My concern is already I have done what you say but still phone memory is not accessible.
As you said A phone's Android is rooted when in Android OS a binary called su is present and executable.
Can you pls. outline how to achieve this
How utterly st-.-pid is that? Why not doing it right and backup the pictures in the first place to Google or sth? No backup, no mercy. How can people be that ....... and run around taking pictures and only having the version inside the phone? I would not invest a single dime in this and if it is you who lost the pictures let it be a lesson to you.
Btw, pretty sure, there is no way of recovering anything here after that wipe.
Dear terry
Not every person in the world is having similar knowledge and resources for backup learn technology. In countries like India 60% population even does not know what is mobile forget about rooting and backing up. Household peoples , housewifes students kids are there who know basic only. I think you will have to to broaden your knowledge about the world
There is no internet ,staorage cloud space with 90% poor population.
What you are telling is considering europe /USA and developed countries.
Don't forget developing and poor countries as well.
I will try even if it is not going to work. But doing nothing and simply telling its not recoverable is not good idea.

Hi there,
I was wondering if there would be a possibility to "DD" or image a android phone. It would be awesome to root a phone and install it to my needs and 'shoot' the image to 20 phones.
Thanks for any answers
grtz
This is both very dangerous, and very specific to the device. Some phones have a dozen partitions on the internal memory, some only a couple. Identifying information, such as the IMEI, is stored in the internal memory. Using dd (also known as 'disk destroy') would copy the same information to all phones, rendering them useless on the cellular network. You could potentially use dd to write to only certain partitions, but why not just use adb?

Sorry for late response,
So there isn't a way to like "Skip" the IMEI etc. and just hardcopy files? These phones are exept for the IMEI / MAC Address identical. So i'm guessing also partitioning is the same?
Partitioning is very likely the same. You risk making a whole bunch of phones useless, however. If you don't mind leaving a custom recovery on the phones, it would be much easier to make a flashable zip file you can flash on all the phones, to put your custom software, APNs, etc. on all of them. You could even restore the stock recovery afterwards, if you prefer (though how you do that would depend entirely on which device you've got).
If you're talking about tens of phones, you might contact the business division of your planned carrier, and they might take care of all this for you, seeing as how you'd be signing tens of contracts.
I am the kind of person who likes to get into an operating system to see what it can really do and have recently rooted my P5110 - I went for the tablet first because I didnt want to "learn" on my more vital device, my S3. After few false starts I got it rooted. However coming across so many things I don't understand, and therefore don't want to touch yet, that I want to find an easy way to learn more about the OS and how it can be tweaked. I realise there is a lot of information here, but mostly you have to know what you are looking for and so a few videos or step by step guides about how and what you can do would be really useful I feel. I also find that that the rooting world seems to have more than a few myths about it- for example one thing I wanted to get around is the crazy and annoying restriction of no longer being able to install apps on, and move apps to, an external SD card. I am finding that although people are saying you can only do this if you are rooted, now that I am rooted I still cant, despite having downloaed apps that claim to do it. They will move to SD but not to extSD which is pretty pointless on the tab because from what I can see apps already go to the internal SD storage. Some people tell me its a Google thing and some say its Samsung.
A few weeks ago there was something on the UK news about smart phone data and how when you sell/recycle your phone most people leave accessible data on the phone after a factory reset. There was lots of trying to shock people (reading out text messages and browser history) but the solutions were barely discussed, all that was said was something like "There are programs that can overwrite your data"
So what do people do when they sell their android phone? I've seen an app in the play store called nuke my device, it basically overwrites the internal SD card then does a factory reset, I'm still not sure that would totally erase all data though?
I know all about methods for PC hard drives, but I too wouldn't mind knowing how android systems should be handled.
Yeah I know about PC Hard drives too. I have bought the nuke my device app from the play store, its cheap, I haven't used it yet!
To block undeleters it's sufficient to fill space with "generic" data then delete the file
As for removing the chip and using an external programmers, some indeed expose raw memory over the pins (MTD chips) and there's no reasonable way to wipe the hidden areas (well, assuming you want a device that still works - otherwise there's the Cobra 6 method), others have on-chip mappers (all SD cards including eMMC) which can have a TRIM command -- which however has historically been a major cause of bricks on some controller firmwares...
When I posted I was looking at some similar threads, someone made a program that deleted everything on the phone except the recovery (then you could flash another rom - I don't know if it overwrote or just deleted) I think it was for an Asus transformer tablet.
Whenever I've sold something before I have just connected it to my computer and written large files to all the available space. I don't have any sensitive data but I like to make sure everything is deleted before I sell something.
I'm surprised there's not more information/apps or whatever on this subject (wiping android) there's lots of programs for PC's to securely wipe drives. Some sites mention about encrypting the phone then wiping it, I guess that's the way to go.
My first thought was too, that it must be different from hard drives.
My initial idea would be to encrypt everything. Luckily since Honeycomb, Android supports this out of the box(but it's not hardware based) So even if data can be restored, it'd be nonsense(if the manufactorer implemented it correctly). You could choose a strong password, because you won't need to remember it anyway since you wipe the phone afterwards.
I found this article that agrees with me androidcentral.com/securely-wiping-your-android-phone-makes-it-just-fine-sell-fud
Then there is this article on lifehacker: lifehacker.com/5808280/what-should-i-do-with-my-phone-before-i-sell-it
Money quote:
Alternatively, there's the ultimate security tool if you're worried about someone pulling data from your phone: don't sell it.

A little off topic: Another solution would be to just store sensitive data on a SD card and remove it before selling. Plus you could use tools like EDS(Lite) to store sensitive data in container. Sync them via a cloud service and open them on your computer with TrueCrypt.
Any updates how to do this?
Boot into recovery and dd /dev/urandom over the /data, /cache and /sdcard partitions, then from the GUI reformat them...
Not perfect but well enough to prevent someone imaging from those partitions to their PC and running an undeleter (or hex editor) on the partition images!
Thanks
Hello,
I am a new Android use, but I have some knowledge and experience with computers (wintel platform mainly).
The Android tablet that I own was given to me as a present, at the beginning of this year (I did not choose it). It's technical characteristics can be seen in the pictures contained in the attached zip file.
My problem is the following: the partitioning of its built-in storage (which I think is 16GB), for reasons unknown to me, is such that the "internal storage" of 1GB (almost) very quickly becomes full from the installed apps that soon these apps cannot even be updated. Most of them cannot be moved to what is referred to as "USB storage" or to the external SD storage.
I would be grateful if somebody would tell me how to re-install the system with e;ither one partition (whatever remains of the 16GB after the OS and other system s/w is installed) or, if the presence of an "internal storage" partition and a "USB storage" partition is "obligatory", then I would like the "USB storage" to be the smaller one (the minimum "required"). Any "data" (music, videos, photos) I will put in the external SD storage.
If the solution that will be proposed requires the installation of a ROM different from the one supplied by the OEM of the tablet, which in turn will mean that I loose whatevet warranty I have, that's OK with me.
Thank you to anybody who will take the time to read this and offer a suggestion for the solution of my problem.

Hi, thank you for using XDA Assist. Android uses many different partitions to operate properly. You really don't want to be messing with them. Unless you really,really,really know what you're doing you will brick your device and make it inoperable. You also won't gain much in usable space. So, while 16 gigs isn't that big, I'd learn to live with it.

Hi jd1639,
Thank you for taking the time to read my post and respond.
Actually, I am not complaining for the 16GB, which is probably adequate for the purposes that I intend to use the tablet for. I am complaining about the fact that the manufacturer saw fit to allow only 1GB (of the 16, minus the approx. 3 that the "system" consumes) for the partition where everything seems to want to work in, mainly the applications that are downloaded from Google Play store. After a very little while, this partition becomes full, to the point where the already installed apps can't update themselves, when the OS finds out there is an update available and "prompts" the user to proceed with the update.
I most ecrtainly don't want to brick the tablet, and because I am not an experienced Android user (as I already mentioned in my original post) I am asking for guidance.
Best regards,
George (geokats56)
I really don't recommend you mess with the partitions. But see this, http://forum.xda-developers.com/showthread.php?t=2234515. Read it very carefully and make sure you understand what you're doing first. If you have any doubts ask in that thread. The guide is for a specific device. Your partitions will be different.

Thanks!
Thanks again jd1639, for taking the time to send me the info.

I'm not at all Tech savvy.
When I go to my Calendar, how do I change the keyboard to numerical and back?
Also, can I change the keypad from Qwerty to a traditional keyboard?
I watched a video that claimed "Quick Charging" is detrimental to battery life.
Is that true? That's the only charger that came with my unit.

So is that like granting you 3 wishes?
What is the device in question?

But that's a discussion for another time.
Yes, well... be careful what you wish for
Your Android is only as good as you organize and configure it to be. Always keep in my mind what do you would need to fully restore the phone if it crashed right this second. That way you will learn to do this almost effortlessly in time. Ask yourself the hard questions, like what would I do if I lost all my contacts? Answer, create multiple backup files that are stored on the PC and data hdds. Do this with all critical data that can't be replaced.
Fast charging is more stressful on the battery. Not sure about that Samsung but if it has the app Device Care you can disable fast charging there.
As for the rest use the gear icon on the keyboard to access settings.
Play with it, that's how you learn. It's almost impossible to crash* a stock Android so explore it.
Do Google searches and learn from others by reading.
Eventually it will become intuitive how to fix issues even when you see behavior you never saw before. The Android platform is many times much easier to use and troubleshoot than the Windows platform.
Play with it... Android wuv attention
* always backup all critical data on the phone redundantly to at least 2 hdds that are physically and electronically isolated from each other and the PC. Otherwise you will lose data, sooner or latter.
If you have a SD card slot, get a V30 rated card and use it as a data drive. All critical data and backups go here. Then backup the SD card regularly. Only the apps, the temporary download folder and the DCIM folder go on the internal memory.
Backup the contents on the DCIM folder to the SD card regularly however Do Not name that DCIM, name it something like Photos 2021.

You're welcome.
Lots to do. It takes time but make backing up your data and the ability to fully restore the apps and data after a crash a priority.
One data is lost, it is gone for ever.
Any apps that allow you to backup their settings, do so. Don't forget backing up important passwords.
NEVER encrypt data drives!!! Do not rely on Samsung SmartSwitch as a stand alone data backup!
You can use Apk Export to make installable copies of all your loaded apps even updates so you can reload them without Playstore. All my apps are backed up like this. Even if Playstore discontinues them... I have a copy.
