How to delete data securely to sell P10 with Custom ROM? - Huawei P10 Questions & Answers

Hi,
I want to sell my P10 with fRomFuture - Stock Rom L29 (B179) with the ROM and root. Before I want to delete all my data and the 32GB microSD securely. I think the normal factory reset is probably not enough so that the data will be deleted securely. What is the right way for selling a phone with custom rom?
Thanks and regards

Sd card put in computer and do a low level format. Phone should be securely deleted after factory reset. Otherwise twrp might help.

A Few Questions on my N7000

Hi everybody! I own an SG N7000 running the stock GB2.3.6. (not rooted) and I am new in this area of Android phones.
Kindly ask you to help please with answers to a few questions I have:
1. How can I change the location where the screen captures are saved from the phone memory to to the SD card?
2. How is it possible to deactivate in the Startup some of the installed applications so that they are completely blocked and are not consuming resources and battery? If possible, would that last over a phone restart?
3. I have performed (several times) a Factory Data reset including format usb storage from Settings > Privacy and I though the phone will be returned to the "new" estate. To my surprise I was able to see the names of the previous installed application by going to Android Assistant > Tools > Batch Installer. Why was the Factory Data reset not wiping out everything in phone's memory, what did I do wrong? What do I need to perform to wipe out all my private data (supposing I will sell my phone sometimes in the future)?
Many thansks for your answers!
My problem is my Data gets Auto shut in background & i dont get WhatsApp messages
how do i keep it on all the time
Please
You are not able to change the screen capture save location.As yours is official ROM,u cannot stop any of the startup apps.
Use wipe function to fully delete the phone or some ppl called it the hard reset function.
Yours Sincerely

Would rooting on GB 2.3.6. solve both questions or is it necessary to upgrade to stock ICS or even to flash a custom ROM?
If a custom ROM is required, which one would you recommend from the stability, battery and speed points of view, including abilility to wipe data without any trouble?

Did I get it right that running <wipe function> from the booting menu is different than performing Factory Data reset from Settings > Privacy?

Device Protection on Android One Useless

I was under the impression that device protection on lollipop for android one devices would work no different than nexus devices .it turned out to be untrue. I was using stock 5.1 lollipop (encrypted) with no changes to the bootloader or recovery. On downloading the 5.1.1 update I went to recovery amd factory reset the device and flashed it with OTA zip file 5.1.1 . I was then able to go through the setup screen on first boot without it asking me for me google credentials of the previous rom.
Thus proving even if your device is looked and encrypted it can be easily reused by flashing the rom.
that happened because you formatted data sir and do one thing re encrypt THE device and wipe data again see what happens

Thats the point.. thats exactly what a thief would do ie format the data and use the device again.Even after format it should have been locked to my google account.
You don't really get the point of the factory reset do you? The point of the factory reset is to wipe everything and set the phone to the factory conditions. That 'everything' also includes your google account. Name one device that keeps an account that it signed on to after a factory reset, I'll name a unsecure device. Even nexus devices don't do that.
Try not to lose you phone.

My dear friend let me explain the point to you. Device protection for lollipop devices acts as a deterrent for thieves. In case you loose your phone, for a thief it will be nothing more than a paper weight . If you read the first post . I forcefully cleared the phone from recovery just as a thief would do because he wouldn't know the unlock code. However on setting up the phone I should have it hit a dead end because the device should have been locked to the google account of the previous user.
Here read this article to know how it works..Hopefully then you will get the "point" http://www.greenbot.com/article/290...ow-about-device-protection-in-android-51.html
Besides device protection will not work on your phone as you have unlocked the bootloader and replaced the stock recovery which defeats the purpose
pardon my ignorance then...
apparently this feature is only working on N6 and N9.

still if a thief knows how to do a factory reset, he's also able to flash a custom rom or reflash the stock rom without having to login in to the device. Which is really easy process with most phones out there.

This is where the locked bootloader comes into play, an average user wouldn't tinker with the bootloader or stock recovery. To install a new rom one has to unlock the bootloader . Now for a thief he wouldn't be able to unlock the bootloader because the stolen phone will be already locked with the pin even the usb cable won't work. So all he can do is factory reset the device ...had device protection been working as it should have he would have hit a dead end there as well.
Don't know why google didn't enable this feature for android one devices .

Data recovery after sudden factory reset, possible?

Hi guys,
As the title says, will i be able to retrieve my lost files after sudden factory reset? i just saw my phone restarted then saw the emui logo which i thought was updating then all of a sudden asking me all the details which was present when using a new phone such as, gmail account, language, time etc.
I already rooted my phone because that was the requirement of all recovery software(dr fone, easeus mobisave, remo) but haven't got any luck of seeing at least some of the files i know was present before my phone did the factory reset.
I saw this post here in xda about internal memory recovery, will it be the solution to my problem? will it work on my phone? or i should stop looking for a solution?
here's the thread i'm talking about:
https://forum.xda-developers.com/ga...de-internal-memory-data-recovery-yes-t1994705
P.S.
after rooting my phone i disabled my wifi/mobile data, removed the sim card and memory card to prevent updates,etc. thus making it overwrite the files i want to recover <- this was the tip present in all sites i visit looking for a solution to my problem.
I learned my lesson now to always backup.
Thank you in advance guys, I hope you guys can help me, sorry if I wrote a long post asking for a solution.

If you are on Marshmallow or Nougat and if you had TWRP installed, you could copy DCIM folder from Internal memory to PC, via TWRP
But to install TWRP, you need to prepare some steps from the System (to obtain Bootloader code, to Unlock OEM) - without the PIN you cannot
With DC Phoenix tool and 15 EU credits, you could reset the phone and start using it again, but it will wipe Internal memory, with the DCIM folder and photos
https://www.dc-unlocker.com/DC-Phoenix-flash-repair-tutorial
Don't know if Ministry of Solutions (maybe little cheaper than DC Phoenix) could break over (Bypass FRP ?), without resetting the phone and wiping Internal memory

- at least, you can ask them in advance, for free

Can't load Andoid system. Your data might be corrupted.

Hi everyone,
Yesterday after pulling mi phone out of my pocket I found it with this message on the screen: "Can't load Andoid system. Your data might be corrupted. ..."
The only options are try again and Factory data reset.
I have tried now everything I could possibly imagine and find online but nothing worked.
Is there any way I can copy my pictures of the phone, from recovery mode via adb for example?
I could also imagine to updating the phone via adb sideload but I can't find a newer OTA then the one I have so it would not update.
Also I could not find a way to boot in safe mode which I think could be another option.
I hope you can help me.
Thanks
Hello,
My sister has that problem also.
You need to put out the SIM card. Do a factory reset, just connect a Google account to get the updates from Android One and install all the updates till September patch without the SIM card... Then put the SIM card in phone and restart.
Normally it's ok. By my sister works the phone now perfectly.
Good luck

Thanks for your answer!
Unfortunately my phone the xiaomi mi a2 doesn't have a sim card slot ... so no sim card. That means to my understanding that all the data is saved on the internal storage that will be deleted with the factory data reset....
Unfortunately due to how Android uses File Based Encryption, your data is effectively lost. Im sorry.
I had once faced this issue too.
As far as my experience goes — there are no way for us to fix this random occurrence. It rarely (extremely) happens, so it makes the situation much worse as it is akin to a ticking time bomb waiting to take down all of your precious data. Till this day I am still wondering what triggered the data to be "corrupted".
My advice is to make use of a backup solution. Whether DIY (simple FTP server on your desktop), or using a cloud solution (Google Drive, Google Photos (free if willing to sacrifice original photo quality)). Having a periodical backup can minimise the damage you would have to deal in the event of data corruption happening again

Thanks for that that honest "bad news". :-/
I spend all day trying to fix the problem and it is hard for me to give up.
So you think there is no way around it?
I will still try to wait until tomorrow if someone has an idea I guess and if not delete...

SIM card is the card to call, SMS and have 4G..
Not a external storage, mi a2 doesn't have it.
Try to restart the phone without a SIM card. By my sister it was that problem, and the phone run on android 8 with the issue. Need to update to android 9.
Hope you can fix it.

Sorry, apparently I was too tired when I read your reply and my brain replaced sim card with sd card :angel:
Never the less I tried now to restart without the sim card but it still boots to the same error.
When you said "Do a factory reset, just connect a Google account to get the updates from Android One and install all the updates till September patch without the SIM card" did you mean by choosing the option factory data reset? This will lead to total data loss right? Or did you mean using a different method?
I think with 10.0.14 my phone runs on the newest version that's why I could not run an update via adb sideload which I hoped could do the trick...
Yes, you need to do option 'factory data reset'. All data will be lost, no other options to fix this issue. Sorry.
Then do the steps I said in previous posts. And restart phone a couple of time without and with SIM card.
Normally it will be fixt and phone runs good.
Good luck!

That was the only solution for my sister's phone. And now it works very well. I hope for you to.

Ok ... Thanks!
All data is gone but the phone works again
I left the sim card inside and it still worked fine.

Again i am sorry. I understand how it feels to lose precious files. [emoji17]
Yes there is virtually nothing can be done. Due to how File Based Encryption works, your key is also encrypted. (yes FBE kind of encrypts the device twice). When you boot into TWRP for example, it would ask for the decryption key (usually your PIN). As for my past Corruption issue, TWRP keeps saying the entered key as incorrect. Until the key part is correct, we cannot get a copy of /data partition (nandroid) to tinker with it later on.
When this Corruption occurs, it effectively lock us out from our data. Even using TWRP won't cut it out. Unfortunately I myself is not expert enough on this matter as the fact that this happens out of blue kind of point out to a flaw with the Android itself. Fortunately it's rare, but i take no risk and subscribed to Google One ever since.
I do wish that in the event this happens again, the user (us) should at least able to use TWRP without providing decryption key, so that we could make an image copy of /data. Then i also wish android would allow us to export the decryption key whenever we want so we can keep it. Then when data "corrupts" we should theoretically able to use the decryption key to decrypt much needed files.
But hey i could only hope.
