[Q] Bootloader unlocked factory reset

Hi,
Today I tried to unlock my bootloader on Xperia T, because I recently downloaded android 4.3. When the bootloader was unlocked, I tried rooting the cell through usb debug. But it didn't work, I decided to look at it tomorrow, or at a later point. But when I restarted my phone, it was been factory reset. Some of the photos were recovered, but ALL my notes are gone and a lot of apps are gone, I never chose to format my phone or anything.
Is there a fix for this issue?
Thanks in advance!
EDIT: my phone contacts seem unlinked from WhatsApp too... So the contacts are there, but WhatsApp doesn't recognise them.... I think the internal memory and the phone memory are corrupting each other
EDIT2: the contacts don't even seem to be there now, not even on Google, while I am 100% sure I saved the contacts to my Google account

I never heard of this issue before, but a bootloader unlock always factory resets the phone. Are you sure that your bootloader can be unlocked, and that it is still unlocked now? For unlock just follow the instructions on the official Sony page, they're clear enough.
I don't know a method for recovering data after factory reset, other than restoring your nandroid backup.

I am sure the bootloader unlock is possible, it might be that I unlocked the bootloader, while it was unlocked already. I don't know if this is the problem.

Did you unlock your bootloader before? If not, then it is still locked. However, the status now is a bit unsure Did you check in the service menu? ('call' *#*#7378429#*#* (*#*#SERVICE#*#*) and check Service Info -> Configuration -> Rooting Status, what does it say?)

Thanks for the reply, I did this, my phones bootloader is UNLOCKED, I was confused and did it again, so i double unlocked the bootloader, this seems to be the problem. Is there any way to get the data back?

Well, good to see your bootloader is indeed unlocked
If you didn't make any backups, there is almost no way to recover your data. The only thing I can think of is trying to recover something with data recovery software like Recuva (from Windows, not an Android app), but you should stop using your phone immediately, because if sectors on SD or internal storage are overwritten with new data it diminishes the chances of recovery of old data.
Now would be a good time to start backing up regularly, or at least before you start flashing roms, unlocking things, etc. There is a reason why we say 'always make a nandroid backup!' :angel:

Thanks for the help and replies so far!

Got Locked out of my own phone

Have you tried wiping data? and photos are on your sd card/internal storage, which is not your system, data, or cache partitions.

or if ur phone is rooted then there are a lot of tutuorials to tell you how to bypass it

Lost pin code... How to unlock phone?

Help.. I have a Huawei P10 (VTR-L09) with Android 8.0 and stock rom and recovery. I've lost the pin code and now it requires the pin after a phone reboot... So I can't access my phone anymore.
Every solution I find on the internet is either only for Samsung or not supported for this phone. Does anyone know how to unlock it now?
Please note that USB Debugging is not enabled in settings as I got the phone back from repair only a few weeks ago so only got fastboot commands. But I really do not want to factory restore it...
Thanks for any assistance!

You could contact your Phone company and tell them you've lost your Pin and PUK. They only need the Numbers from your Sim-card.

Thx for your message GAMaus, but I've lost the phone pin and not the SIM pin. Do you think they can really help me with that?

my friend was with the same situation, he goes to service center and they fix it but he lose all data.
or try with some gsm repair service maybe they can unlock without losing any data, but if your device is encrypted in my opinion is not possible without factory reset

It's not possible to unlock your phone without the correct PIN. Only chance to get into your phone is to wipe data in eRecovery. But this will remove all your user data except the data on SD.
You're also not able to get your data through TWRP because the /data partition is encrypted. To decrypt, you need your PIN.
But there's one question I have: The P10 has a great fingerprint reader and you're telling me, that you didn't assign your fingerprint for unlocking your phone?

he probably was forced to put his pin because of that 3 days option

Yeah the fingerprint doesn't work after startup because Huawei wants you to remember your pin... But fortunately I could try endless possibilities with the pincode (only sometimes I needed to wait a few hours). But in the end I got the pincode correct, so I can use my phone again
Thanks everyone!

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

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.

I forget the password and I want to copy the photos

My phone is at&t LG V40 ThinQ (V405) and I have forgotten the pin password.
As you know, I cannot access to everything without the password. I connected it to the PC and the files won't show up.
It turns on without problems, but it asks for a password to unlock the screen.
I can hard rest it, but it will erase everything. I cannot even root it because I need to enable the developer mode and allow the bootloader to be unlocked via the setting.
Is there is any way that I can retrieve the files via PC?

Are the photos saved on the sd card? Another good reason to turn that on if you didn't.
There is an frp partition for vzw phones that enables oem unlock, not sure it would work for a different variant though. Have you ever connected it with qfil? U don't need root for that, and in edl mode, you could save off user data (which is huge, like 40 gig I think). Not sure if your pics would be in that or not actually.
interesting problem. good luck.

No. The files are not stored in the SD.
Any detailed instructions to your suggestion is highly appreciated. Thanks

wish I had detailed instructions to give you. I've never been in that situation, or resolved one like it. I pointed out some avenues I'd explore it it were me... but it's not.
maybe you'd like to look more closely at those avenues, maybe you wouldn't, that's your choice.
