Freebie without lock screen code - Xperia Z3 Q&A, Help & Troubleshooting

Hey,
Our company some time ago exchanged all Android phones with iPhones. The Androids are still piled there and I got permission to get a Z3 for the kids. Loading worked despite the long time without power, but the user did not reset the phone before returning, so I am now facing the lock screen with no code and no Google account to reset. The methods described to enter recovery mode do not work, I assume due to missing USB-debug option.
It probably is a D6603 with a Deutsche Telekom branded software (shows the pink T before the lock screen).
Is there any chance to use this phone? I don't mind fiddling with hardware if necessary (actually I like fiddling with hardware ). If not, I didn't pay for it, so no damage, but I do not like to throw away things that could still be used ...

[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.

Locked out of phone in China!! :/ S6 SM-920F

Hi!
So I have a Galaxy S6 which came with a Dutch T-mobile package. On my way to China, where I moved a few weeks ago for an indefinite period, I cracked the screen and brought it to the local repairman to fix. That went perfectly well, but the phone didn't recognize my fingerprint anymore and I forgot my backup password. That's why I performed a factory reset, and that's where the real trouble began.
After the reset, I tried setting up the phone again, and got to the Samsung reactivation screen. I entered my account info, and provided the password for the wifi, after which the phone connected to wifi (with the corresponding message), but after a few seconds I get a pop up message saying "Unable to connect to the Internet" - even though the wifi symbol would still flash its arrows in the upper right corner. Thus, I can't get past this screen nor in my phone, which is quite a devastating fact as a poor new expat in China . Tried several other wifi networks, to no avail.
My guess is that it's the Great Firewall of China acting here, somehow preventing the phone to connect to the Samsung (and/or Google) network to check my info. I don't know if this is correct, the Samsung helpdesk couldn't say for sure as well, but I really really want to find a workaround here. Once I get the phone working again I can install a VPN to have the Google stuff working in China, but this way I can't get to that point. Now I am completely new to rooting/ installing ROMS and the works, but I am willing to try anything to get this expensive piece of electronics to work out here.
Any helping comment is an absolute lifesaver, and I will name my firstborn child after you!!
Thanks so much!
All the best, Maarten

Assistance with (partial)Bootloop and Locked Bootloader.

Hey there forums.
I've been an active browser of XDA but never really created an account but I've done so to have assistance with a particular situation with my device.
So the other week, i had spent 150 dollars on a Sony Xperia XA F3115 from Vodafone, Australia and it turns out that the bootloader was locked because of Vodafone and i wasn't going to pay 50 dollars to unlock it. I alternated and browsed the internet (Mostly XDA but other sources aswell) to figure out if there were any methods of bypassing this, whether it be easy or not - I was willing to try anything that seemed like it had a chance to work, without a 100% failure rate. Reading responses to particular methods, i was drawn into one method of just reflashing the stock firmware onto the device and then rooting, flashing and doing everything from there (as the device was no longer locked by Vodafone at that point).
I have completed this task as of this morning, and the device booted successfully. As soon as i unlocked my device, i had received the general android setup window but half way through, i got spammed with "Name has stopped responding" countless times to the point where the phone was literally unusable, it would just pop up again right after closing it - So i decided to restart the device. This was probably a big mistake, it booted fine but it said "Android is updating" and had the whole "Applications updating 100 out of 255" stuff happening. Then it booted to the lock screen, which i had previously setup before i flashed the device which didn't really surprise me too much.
Then it rebooted. Now every single time i boot the device, it reboots to the "Optimizing apps blah out of blah" and then will reboot upon the notification bar popping up, but no lock screen. I decided that my best cause of action was to download another firmware and try that one instead, but I'm unable to boot my device into bootloader mode as it's impossible to happen. I turn off my device, plug it in and hold the volume down button but it refuses to work anymore.
Now that the situation has been explained, I'd really like your help to see if i can have this resolved. I'm baffled as to why Vodafone even locked it to begin with, since the phone was prepaid and had nothing to do with any sort of plans - nor was it even available as a plan. I don't have the money to buy a new phone, and they have already denied me a refund. I need this phone for work and the mistakes i made were stupid - Please, i need assistance. You're all hopefully more tech savvy than i am in the field of mobile phones.

Locked out of Galaxy S7, can't afford to lose data on phone, need help now.

Hi,
Yesterday I set a fingerprint lock on my S7. It prompted me to enter a backup password and some other password, both with different requirements (one only had to be 4 letters, one was longer and had a number) and the longer one had to be confirmed whereas the shorter one did not. I set this up and tested it a few times, everything seemed to work great. Later I let my phone idle and it turned the screen off on its own for the first time, ever since then the phone has not been able to recognize my fingerprint. It doesn't even say "No match", it just acts like I'm not even putting a finger on it at all.
Tried over and over and eventually tried the backup password, which for some reason is the shorter one without a number. I put in what I am absolutely sure I put in, and it wouldn't take it. Tried a couple more times, even got so desperate as to emulate potential typing errors I might have made (since no confirmation for that password) and nothing worked.
Eventually I hit the timed lockout and I had to stop trying things then. So I went online and searched and discovered Google's Android Device Manager. I heard that if you lock the phone with it you can unlock it through the same manager and the phone will be unlocked. First thing that was odd was that ADM didn't give me an option to enter a password, just a contact message and phone number. I still put in a message and hit lock, and... nothing changed on ADM at all.
Now my phone shows the stupid message every time I wake it up and every few seconds on the lock screen (I can still attempt to unlock the phone with the password and use phone/camera though), but ADM doesn't even give an option to unlock, just change the locked message. I can't even get rid of the damn lock by changing it to blank. I heard Samsung offers a similar service but I never made a Samsung account and apparently one is required to use it.
Beyond that the only solution I've found is wiping the phone (which I can easily do, because there's an option in ADM for it which presumably works), which I really don't want to do since I have a lot of pictures and data on the phone that aren't backed up that I would absolutely hate to lose.
To make things worse it appears that this issue is specific to my phone/the S7/Samsung phones/something, as I have my old Nexus 4 listed in ADM as well and going through the options for it I see it has the ability to define a password, but no such thing for the S7. I really have no clue where to go from here, tons of googling hasn't found me any method I haven't already tried or can't do.
I'd be so grateful if someone here would at the very least find a way for me to recover data before wiping it to get rid of the lock.

Android 9 : Apps crash when screenlock verification ...

Hello folks,
Happy Sony user since stone age , I have a strange issue with my xperia XA2
Smartphone (powered by oficial Sony Android 9 ROM) :
When an app is requesting for screen lock verification (eg for Ms Authenticator, Volvo app, ...), the app restarts
or loops at security prompt, whatever I provide correct PIN or Biometric.
I already gave a try to unset screen lock and reconfigure biometric without success.
Turning off screen lock, prob is gone but phone is unsecured, being not possible.
For the rest, the phone works perfectly, great battey, no issue.
That makes me crazy, not being able to fix that small issue.
any idea what can be broken ? Any tips ?
Thanks
Cheers from Belgium

Do you really need a screen lock?
It's more likely to lock you out rather than a stranger.
Sometimes through no fault of your own as with a hardware issue or data corruption.
If no lock is set, no problem. I lost access to a laptop bios like that. Even after 5 years I remember the simple password I set... useless.
The only real security is physically possession. Anyone that wants my phone will pay a steep price... it stays with me, always.
Yes, need phone to be locked... And with eID, banking and MFA apps, having your unlocked phone lost/stolen/... is very dangerous !
Thanks anyway !

Trying to steal my phone is extremely dangerous... no free rides
You need to weigh usability verses risks.
You also should consider what will happen if you lose access to the phone especially at a bad moment. At the very least it will cost you time and loss of use.
