Is my phone hopelessly locked or there's still second chance? (Forgot pattern, USB debugging on but not OEM unlock so can't flash) - Xperia Z3 Q&A, Help & Troubleshooting

So basically I have a Stock Sony Xperia Z3 Docomo variant (if I recall correctly it was D6653) that I used all the way from 2017, until I had to let it rest in 2020 because the screen was broken (although at that time before the screen went completely messed up, I managed to enable USB debugging in order to mirror the screen on my laptop with scrcpy so I can use it). It's just laying down on my desk cabinet for two years. Until finally I got a chance to replace the screen, the battery and the back cover earlier this weekend. Problem is, I already forgot the pattern to unlock it. Not even my brother (who used it sometimes to game back then) remember the pattern. Worse part is some of the SIM card, even when it does have data plan (I just simply put the SIM from my other phone), the phone is just going to show as full bar Roaming (R) and no internet at all so this phone completely have no network (although I do also have suspicion that data connection is probably disabled), and obviously that means I can't use google account to unlock it
Wanted to use TWRP or Aroma File Manager to delete the pattern lock file, but then I realized I have to flash this thing, and even if I do now understand how to install TWRP on my Z3 model because I already read various tutorial on this forum since Saturday, the problem is that OEM unlock isn't even enabled simply because at the time it was still a bit functional, I don't see it as something I need as I don't root any phone that I use. And as additional note, as time goes on obviously all of the laptop at home had gone many clean reinstall, which means no ADB key backup, and I can't authorize because pattern lock
Is there hope left, or this phone is completely locked?
(TLDR: Phone locked because I forgot lock pattern, no Internet, data stuck at R, no connection so I can't recover with google account, USB Debugging on but not OEM unlock)

[Q] Xperia J locked in Emergency mode- but an unusual tale maybe Mission Impossible

Hi all,
I will be eternally grateful for your help but I am not holding much hope.
I got this new phone from my operator Three in the UK back in January this year.
All works ok except for the screen calibration which I did not get round to fix.
On Monday I decided to put a pin lock on my phone, as I haven't been using
the pin lock for a few years now. I chose the pin code, then I stupidly tried
"Lock Sim". Then the screen came up with sim locked, PUK needed.
I did not make even one attempt with the PUK code as I decided to phone
my operator for it. We went through the procedure, he gave me the PUK
code and we managed to unlock the sim card and then I remember the
pin code (as I always have) and inputted it and the phone is unpinned.
I need to mention that we did have one or two bad attempts where
I couldn't hear the technical guy too well and I did enter the wrong pin
once or twice, but less than the 3 attempts limit and we did have to
take the battery out 3-4 times due to this and also because
I kept putting the sim card the wrong way round being very careless.
The sim is unlocked but on the screen it is "no service" emergency
calls only, where if you choose the emergency option green button
it will give you a menu and * # . I can see some symbols on the top
such as wifi connected. If I call this mobile phone I can pick up
the call, the screen has the usual answer or reject phone symbol on.
But during and after the call pressing the home/back/menu button
on the phone (off the screen ) have no effect. I told the technical
guy about this. He suggested a new sim but if I put my old sim
in my other three pre-smartphones phones it works. However
this phone is tied to this sim card/phone number only as I try
my other sims on it and they do not work.
I have tried a few things:
the 7378423 thing with all the right *#, doesn't work. but 06 works to get IMEI
cannot enter fastboot mode holding down the volume up button and plugging
USB in, but can enter flash mode.
I do not want to lose data as I have some important data which I haven't
backup to my sin so I don't want to use PCC or SUS to install either
the current OS (I think it is ICE cream 4.04 ish) or the new jelly bean.
To complicate matters my phone is not USB debugged enabled so I
cannot use software to do a quick backup of my phone I tried
mobile me from wonderware(?) and its needs usb debugging.
PC companion doesn't have restore and backup anymore, or at least
not for xperia J as the Sony support guy told me, if it does it probably
needs debugging enabled.
Talked to Sony support, he said the only way is to use PCC to reinstall
software and I will lose data as expected. I asked him if Experia J
and the newer Xperia phones have disabled the 7378432 service
code and if there is a new one which he can tell me. He says there
are no new codes.
The phone is not totally now working, I managed to get into "safe mode".
I wonder if the phone actually is rooted or has bootloader unlocked I
read if that is the case it may explain why the 7378432 does not work
as it only works on sony stock rom. But then I came across other people
whose phones may not be bootloader unlocked and this code does not work.
I also came across people who cannot get into fastboot mode.
Maybe because my batch of xperia J, together with customisation by
my phone operator has disabled 7378432 and fastboot which I don't thin
so as Sony themselves mentioned the use of these two important
elements in their unofficial but be warned section on unlocking the
bootloader. I wonder when I took out the battery a few times when
I spoke to the technical guy my phone is locked due to security but
as I said before the PUK code was entered correctly first time round
if not second time round, so is the pin, We just took the battery out
and retried about 2 times as my sim was in the wrong way round.
Finally my apologies for the long post, the phone still has my wallpaper
on it and the error message I used to get from an app (telling me the
app is not working) when I turned on the phone. If the phone was
flashed/rooted then it was not done by me, it might have been done
by a previous owner and then returned to the operator within 14 days
and then my supposedly new phone is this rooted phone. Without
usb debugging enabled its hard to go into recovery mode via
usb link/flashrom/boot etc? But if we know which rom we can
try to go into recovery mode without a usb link by pressing a few buttons?
At the end if I have enough money which I don't sadly someone at sony
can probably take the phone out and do some high level fixing, as long
as the memory is still in tact which I hope it is. For some reason the
phone is locked in this emergency calls only mode. I have not made
any attempts to root it etc before Monday and no attempts to root it.
I just thought the 7378432 can "unlock" a phone lock like the much
discussed xperia Z - if the phone is on a pin/pattern lock etc.
My attempt to go into fastboot mode is to hope that by getting in
and getting out of it the phone will reverse back to normal. My situation
is mainly complicated by that I really want not to lose the data, sms
particularly when we try to unlock/unfreeze the phone.
Extremely sorry for the long post, if anyone can help I will be
most most grateful, bye for now.

Xperia Z3+ dual - Need to remove screen lock

Due to some personal issues, I was not using my phone since the past 6 months. Now when I started it back, I am not able to enter the proper screen lock(Pattern) and I never ever made an account on myXperia. I tried many ways which included google find my device but find my device is not allowing me to change screen lock, it just allows to make sound and "Lock and erase" option which basically does nothing.
I actually need my data intact and after a little search on internet, I came to know that i need to unlock my bootloader and then flash a recovery and remove the screen lock file but unlocking bootloader will result in factory reset and hence my data will be lost.
By default the phone doesn't allow usb debugging when connected to pc, if some how I am able to allow usb debugging then I can recover my data.
Please help guys.

Forgot KnockCode Lock on LS777, need help figuring out my options

Hello, I recently found an LG Stylo 3 in one of my drawers that has a knock code on it. I don't remember the code and I already tried 66 times to unlock it (it now takes 240 seconds between each attempt). No "Forgot Password" or backup pin option shows up, USB Debugging is on but it's unauthorized, and the mode that it's on when I connect the phone to my PC is Charging Only. I just want to know what pictures I have saved on it, or if I can pull out my photos or something. I can't reboot into bootloader from the recovery options, it just reboots my phone. I'm able to go into recovery, and safemode, update from adb puts it into sideload mode, and it's connected to my wifi but because I changed my passwords on my google accounts already, the phone doesn't show up in any of my google device manager accounts.
Everything is stock, no custom recovery or firmware and it's not rooted.
What can I do now? Is there a way to reset my password or bypass it entirely? I don't care how technical it is, if given a good guide I can do it. I can't find anything to help me, hopefully someone can help my problem here.
Before anything, I didn't steal the phone, it's my old phone I had when on Virgin Mobile, I can give as much proof as I can to show that it is my phone if needed. I just don't remember the knock code
Thanks!

Recovering data through USB

Today my phone felt down totally flat. The screen hits the floor directly.
It carries a protector above the screen, and apparently it is the only part that broke down
The screen seems to be in perfect status.
But the problem is screen is not working. None light is shown, and no reaction is performed.
If I touch the power button during 20s, the phone vibrates and it seems to be restarted.
When I connect the charger, the led works fine. Although no sound is played.
I would like to repair the phone, but at least (and this is important) I need to download all the data to the PC.
Question: is there any way to access to the data in the phone without having the screen available?

If you did not USB debugging enabled in system settings before the screen broke, you will not be able retrieve your data. Now that your screen is broken, there is no way for you to enable USB debugging in order to retrieve your data.
Your options are:
1) repair the screen so you can retrieve your data.
2) forget about your data and get a new device.
Live and learn. I keep USB debugging enabled on all my devices for this very reason.
I found that I can retrieved my data thanks to custom recovery. I had a bit of lucky because with adb, data can be retrieved trhough custom recovery.
Usually, I have USB debugging activated but this time it was not activated as from last ROM update it is deactivated by default.
Now, I will deassembly the phone just to understand which is the root cause as touch sensor is working fine. So I need to understand if the problem comes from the screen or in the worst-case from connectors or PCB. In this last case I would need to get a new device, and I would like to keep this one for a few more time, even when there is no more OS update.

I was going to suggest that but wasn't sure you would actually be able to install it or even if a custom recovery existed for your device since you didn't post what model you have. Also, if you had needed to unlock your bootloader to flash a custom recovery, unlocking the bootloader would have wiped your data.
Yes, you were lucky, most users in this condition are screwed out of recovering their data.
