As anyone EVER recovered data after a Factory reset? There are so many people who just give blind advice to use android recovery software which actually doesn't work. I have contacted all data recovery they claim it's not possible after Android 8. If anyone has recovered data after a Factory Reset in Android 10. Please Share your thoughts. Also, I have contacted Data recovery specialists across the World who mentioned It's not possible after a factory reset.
Rooting OnePlus 8 ain't easy task. Also I spoke with stellar they don't support after Android 8.

Never got any answer
the answer is keys are lost with the deletion.
Ok. So you mean anything which is permanently deleted on android 10 is not recoverable? I am not sure of key deletion I just googled and got tons of articles with different opinions. I will be glad if you explain it better here.
there are tons of opinions but there is only one truth.
Completely securely deleting a single file
My impression is that, if one wishes to be able to delete a certain file completely, without wiping an entire drive, one should never store it on an SSD. Is that right? Even with whole-disk-encry...
unix.stackexchange.com
True. My last question which I need some clarity. I read encryption works only when the screen password or lock has been set. Since this phone was used by my parent they never had any screen lock or password set. Not sure if it's encrypted without a screen lock or password. As I read it phone encrypts only when the screen password is set,. can you throw some light on this? I would really appreciate it.
Doesn't matter. In case no screen lock provided, KDF generates KEK without credentials. each file is encrypted with Per File Key that gets deleted together with file.

I permanently deleted some pics from my Android phone. Is there any way I can recover the pictures? This is Oneplus 8. Android version 10. I believe they come with file-based encryption from the factory not sure though. As I did a lot of googling I understood the key is lost with the deletion. can someone share if there is some way that I can recover the data?

It seems possible to recover the photos, as long as they were not overwritten by other data.

Hope that helps.
@wenyendev kindly read the answer you have just linked:
But first of all, see this answer to make sure your data is recoverable.
In short, recovery is more or less possible only if:
Your deleted data hasn't been TRIMmed or discarded.
And you haven't done a factory reset on encrypted /data partition.

I have been using the GS2 for 3 months now with no issue. This Saturday when I was out with some friends I tried to use the camera and couldn't get it to turn on and a line "security policy restricts the use of camera" popped up. I checked the Exchange Policy in my Exchange account and sure enough it was disallowed but it mysteriously went back to normal after 24 hours. I then checked with my company's IT and he said he didn't touch it at all over the weekend. However after hearing about it he then proceeded to turn off the use of camera as he felt this is a security threat. Now both my GS2 and Galaxy Tab's camera is inoperable. However, other phones that are connected to the same Exchange including HTC Android phones, Blackberry and iPhone are unaffected with their camera still working. My IT is convinced that the Samsung exchange client is the problem. Has anyone else has this problem? I love my GS2 but if I cannot use Exchange then I will have to force to use something else.
Have you solve this Issue??
I`m having the same problem with Tablet and Exchange. I will check exchange policies.
Easily overcome, there are modded apks which bypass the policy. Here's my version which I've modified.
http://db.tt/oFqciCcF
I assume your rooted, just copy and paste the apk into system/app using a root explorer and change permissions to:

Please wipe data after replacing it, and reboot device.

how can i remove remove this security? its also restricted "Mass Storage" "USB connection" and the "Camera".
I already did "Flashing PDA" , "Factory Reset" and also I tried JTAG. I killed it because I tried to flash some file. but now its revive again.
policy lock is still on the phone, it has sign of padlock on top of the screen.
i think EFS reset can remove this kind of lock.
Better and simple (but it took hours for me to find it):
- Your GN2 needs root
- With Root Explorer or Total Commander, delete all files into \efs\security (especially the ones regarding DMM...)
- Backup with Titanium Backup if you wish to recover your apps.
- Boot into Recovery (Vol Up + Home + On/off) - Wipe all Data/Factory Reset - Wipe Cache
Of course, this will erase all on your mobile... including each security policy that has been implemented: Camera, SD Card, Bluetooth, USB connection, ....
Deleting DMM... without wiping will leave the security policies unchanged as DMM is read first by the GN2 at booting, and then other system files are modified accordingly.

Though it would help anyone who would want to try and help if you provided some more information on the nature of the issue and phone.
For example knowing the disposition of the phone (how you got it, is it a demo/retail/company provided/etc), what kind of phone it is (snapdragon, exynos), model of the phone and how MDM was (or would have been) activated on the phone. MDM isn't there for no reason, and it would seem (reading what little I did on those Google Searches) the solutions would kinda seem too tailor towards the reason:
For example:
You work for a company (or of your own accord) that installed Mobile Device Management profiles
This is a demo unit from a store
You installed an application that configured MDM
You may have tried installing firmware (official, custom, unofficial, etc)
well i think im gonna keep using it as demo there is no help any where .exept the 120 usd to drop the file for parmanent remove of that demo .

Hi there. I had the same issue on my samsung Note 10.1 2014 edition I purchased as a demo unit. tried flashing stock ROM using ODIN with no effect and unable to factory reset. finally, this was how I was able to factory reset by tablet with all the retail settings including all the preinstalled videos and images gone.
1. Firstly, your device should be signed into your google account.
2.Enable find my phone in settings
3.Go to your google account (in the same device or different device).
4.Go to devices and select lost device
5.press "consider erasing" device
And Voila, the tablet was reset to stock android with no retail apps or data.
Hope this helps someone.
Thanks

Interesting
But I doubt this flaw will work on latest devices note 8, j7 pro,. Just to mention two of the devices I have got.
Also some MDM implementations will not allow you to enter settings menu.

My Phone Storage is supposed to be 16 GB & it is supposed to be free because I just got it a few days ago yet it's full & you can't even know where the data is distributed
there is more than 8 GB that's missing in air
I tried most of the known apps to clean or to remove cache & nothing happened
there is an app that I installed once & didn't start up saying that the phone is rooted
so I downloaded root checker & it said that it'sn't rooted properly
then I used Storage Space app & it said that the phone is only 8 GB
& all the apps say that the phone is only 1 GB Ram
What do I do is the phone rooted or not or is it rooted non properly or is it damaged in storage or what
It's Huawei G9 LTE it's read in many apps U2 or Honor something
here is pics of every information about it

It looks like you got a fake clone phone, not an authentic Huawei G9 LTE. Your firmware / build number is not authentic Huawei firmware.

Flashing a ROM when your phone is rooted is generally a bad idea.
Wish I could help you but clone phones are a huge pain in the butt to work with. I've seen them with corrupted recovery etc, no way to format the phone, limited fastboot commands, etc....
You probably won't get a lot of help on XDA for a clone phone but you can try the "Chinese Models & Cloned Phones" forum over at GSMHosting, it seems active with lots of topics / information
Its a forum specifically for clone phone software etc.

Hello, I am a Redmi Note 9 user,
And I want to the bootloader of my phone
My warranty is already expired, so it won't be voided,
I Have a Qualcomm processor on my phone, so any Mediatek methods will not work,
I already said that I have a laptop and I have introduced myself in this thread:
Hello, I own a phone that I want to root
Hello guys, I own a Xiaomi Redmi Note 9 Pro and I want to unlock the bootloader and root it without losing any data. But I can't find a method that works for me, I have a Qualcomm processor, and no method works. I also don't want to buy any...
forum.xda-developers.com
I recommend you to visit this thread first.
Is there any method I could unlock the bootloader and root my phone without losing any data?
And also don't tell me that I need to buy any paid programs, I don't want to pay to unlock my bootloader.
Is there any way to do it without erasing all data?
There is no way to unlock bootloader without wiping data.
I really am surprised sometimes that people prefer to write some new post that is the same as other posts 89653654645762 instead of using a search engine and finding a topic that interests you. You have written a post in the Redmi Note 9 Pro device section and it was hard for you to go to the guides section and look for answers to your questions?
Here are 2 topics that have answers to your questions:
First link
Second link
It took me a few seconds to find these two answers, it's not really hard, just people are lazy.
You can't. Just it.

It is like a factory reset - the phone goes back to stock, no user installed apps, no user files, no user data, no user settings. Do a backup first (google or MIUI).
I want to ask another question: what is the best free backup tool that I can install on my laptop and connect my phone so I can backup EVERYTHING, like the data of the apps, all the files, all the setting and everything!
And also: Will it erase data on the SD card?
I don't have a need for backup other than built-in Google. There are other solutions, you should use Google search or Forum search for that.
Regarding SD card - if it is setup as removable storage then it should not be erased, but to be safe I always remove it b4 factory reset. If SD card is setup as phone storage, then it will be erased.

That looks like portable storage. To be sure, unmount it, remove from phone, attach to computer and check you can see all the content in a file explorer.
Hello, guys, this is an update, I removed the SD card from my phone and now I'm using Xiaomi cloud backup tool. What will it backup?
I want to backup Apps, The entire filesystem, app data, settings, and everything.
Will it backup all of that?
Edit: It finished backing up and it's the total size of 3.9 GB but I have 74.43 GB of space occupied by the filesystem, what did it actually back up?
I know that google play store can back up you installed apps, but not the data! Please tell me what did it back up.

Thank you so much
This you?
Make sure all needed permissions are enabled including in all associated apps like Wearables.
Try a network reset.
Try a hard reboot.
Clear system cache on the boot menu.
Try in safe mode.
Was the phone factory reset after the last major firmware upgrade? Was SmartSwitch used?
What do you mean by "Make sure all needed permissions are enabled". Which apps are needed to check the permissions?
Why should I need to reset network settings?
Already tried cache clear but did not work.
I think I should need to know on which apps this function depend as I disabled bixby, AR and other things i don't need when i bought the phone 2 years ago. But the Device output function was working then.
Tanks in advanced,

Look in the individual app settings under permissions. Android 12 may have other grouped options for this. The app may not have auto setup permissions properly.
Always try network reset when having connectivity issues; you'll need to reconfigure bt and wifi settings after this. Probably VPN too if you use it.
Those apps you disabled aren't dependencies or parent apps. Others may be... Google play Services maybe as well as some Samsung system apps. Not sure as Pie doesn't have that feature. Not present in Q either, I believe.
Play with it, explore settings, read other's solution (doesn't need to be the same model or even OS version to be applicable many times) eventually you'll find the solution.
Which is the app are you alking about checking its permissions?

All related apps... I'm not holding the device. Unfortunately there's always a learning curve with Androids.
edit: On second thought I'm sure a factory reset would do something for you.
What I tried to pilitely point is that your answersars have no value. And, of course there's a learning curve everywhere so it would be nice next time you reply on the forums you make sure you've already attained the learning curve point.
If someone knows what should I check in order to fix the issue, it would be nice to let me know
If it's not the case, It would also be very nice to not make people lose their time.
Thank you so much.
