data recovery from dead gpu z3 - Xperia Z3 Q&A, Help & Troubleshooting

Hello
so after filming for 5 seconds underwater my z3's screen turned black and turned off permanently. though it seems to still turn on normally
after unsuccessful replacements and search on the internet the logical explanation was that the gpu is dead
so now i want to recover the data (photos, videos, music) i have on the internal memory
the device is locked by pattern lock so i can't access it when i plug it (it just detects the device)
i want to know if flashing will remove the lock without clearing my data
and if so how can i do it with a dead screen
best regards

I can think some ways of doing data recovery...
1: Safe method if you have recovery!
you can do a soft reset by pressing the button on the side of the sd card/sim tray.

}
Press it till it vibrates for a second time, this time it will shut down.
After this, you can turn on your phone and enter recovery (if you have a custom rom or kernel), in this mode you can fetch your files from the internal storage by connecting it via usb to your computer.
2: Use as last resort and confirm the internal storage wiping before doing anything...
Unlock bootloader (I cant remember if it does erase the internal storage partition or not) to install a custom kernel that has recovery.
3: Probably the second safest but it's needs searching the tools if you don't know how to use adb.
If you do have USB Debugging enabled in the phone, you can try to fetch files by using adb in your computer.
Open a CMD in the directory where adb.exe is located and write this code
adb.exe pull /sdcard/ c:/sdcardbackup/
Click to expand...
Click to collapse
It will fetch your files from internal storage to a folder called sdcardbackup on your C:/ drive
Hope this can help you!
If you're going with flashtool, you need to wipe the data partition called userdata since there is where the config is stored but it also wipes the internal storage

hello thanks for the reply
1. tried no luck
2. bootloader is already unlocked and phone is rooted
3. i remember unlocking usb debugging (always do on android) so i will try this, i'll keep you updated on the results
best regards
update :
for whatever reason the phone isn't authorized anymore and i can't access it. anything i can do about it

Hi, as your bootloader is already unlocked try to continue with 2.
If you haven't installed a custom kernel try to install a kernel like EliteKernel, you can find it here in the forums.
Use flashtools and flash boot.img via fastboot mode on your phone, that way you will have a recovery working.

update
flashed Z3FotaTWRPV5.img into it and got it to boot to recovery
i just got my pictures including the picture that killed my gpu (ironic)
anyway thanks for the help... can i edit this to solved?

Cannot Factory Reset Phone

I have an HTC One XL(Evita, At&t)? I purchased it from a third party. The device is rooted and unlocked.
My phone's battery died. Once I went home to recharge it, the device was unable to get past the white HTC quietly brilliant screen. I would reboot it by pressing the volume down button + power button to reboot it and factory reset it. However, it continued to do this action. Then, I chose to reboot it under some setting. After I rebooted it, the device went to a "teamwins" screen. I erased everything, including the rom. Once I did this, it re-booted the device and continued to be on the same screen. Since this action happened, I connected it to my Windows 7 PC. I noticed that my HTC could not be identified as an external hard drive, it was identified as a CD rom drive.
I tried to fix this problem by looking at other forums containing this topic. Here is what I tried:
- I tried to go to HTC support. I downloaded the current system, and tried to use it. When I tried to use it, it kept saying error.
- I uninstalled the driver and tried to re-install it, it came back as a CD rom drive.
- I restarted my computer, pressed f8, and put disable driver signature.
- The driver re-installed as a CD rom drive.
Can anybody help me identify my problem, and a solution for it?!? Thank you so much
You need to relock the boot loader before running an ruu.
Fastboot oem lock
Did you do a reset in the boot loader or recovery? If you did it in the boot loader you just corrupted the sdcard and need to reformat that

How do you relock the bootleader, do fastboom oem lock, adnd reformat the sd card?
I resetted in both, I believe. I haven't touched my phone in over a week

Do a quick Google search for 'fastboot files'
Extract somewhere like C:\
Open command prompt
cd C:\fastboot
fastboot oem lock
Don't format the SDcard

And when you wiped system in recovery your phone had no Rom to boot up into so that's why you couldn't...search fastboot and learn a bit on it like grim said and than in fastboot do the command he said to lock your bl than run the ruu

Should I connect the phone turned off or on?
Also, when I type in the command without the phone, I get: 'not reecognized as an internal or external command, operable program or batch file'

Samsung GT-I9060 Phone Stuck at Battery Charging Animation

I have a Samsung phone model GT-i9060 with Android 4.4 and suddenly one day phone suddenly switched off and refused to start.
On powering on it would get stuck to this battery animation screen:
{
"lightbox_close": "Close",
"lightbox_next": "Next",

}
On holding the Power+VolDwn+HomeKey I get this Warning screen with two options to continue to recovery (VolUp) or reboot
and selecting either of those options leads to these following screens: recover mode boot screen
But nothing happens then, It switches off again after 5-10 seconds on both the screens and I tried
Code:
adb devices
during all those stages but phone is not detected on PC
I need to recover some critical data from this phone which is paramount. Can someone guide me as how should i proceed with data recovery or extraction?

Seems to me that your issue is caused one of these 3 reasons.
1) the battery is failing
2) the internal sdcard is failing.
3) the internal storage is completely full and has no more room to cache files when booting or running.
If it caused by the lack of space to cache files, try booting into stock recovery then use the "wipe cache partition" option(do not choose the "factory reset" option) this will clear the cache and allow the device to boot if that was the issue.
If you know the exact firmware build number version that is currently installed on your device, you can download a copy of that specific build number firmware and flash it via Odin. As long as you use the exact version that you have, it should not wipe your data when you flash it. Then, if it works, you should be able to boot the device normally and retrieve your data.
If the issue is caused by a faulty battery or a faulty internal sdcard, it may fail during flashing, if this happens, it may render the device inoperable.

Trying to backup a locked Android Phone

So I have a small problem that has giving me a headache the past few days. I got an old Nokia 6.1 from my mom & was asked to get the pictures & documents from it. I removed her pattern lock, because I was annoyed to use it all the time. A couple of days later, the phone has out of the blue a security pin. Which obviously no one knows, because no one configured it...
I spent hours looking different ways to extract the data or to bypass the lock & sofar I think I ran out of all the options.
Here is my current state & I would really appreciate some advice how to proceed.
1. Find my device:
The phone is on the list. But it shows that the last activity was on the 10th january & can't be reached it even though it's connected to the internet via my mobile data. Furthermore it seems that I wouldn't be able to unlock it anyways because it only gives me two options "Call the Phone" & "Set up secure & delete".
2. Installing Aroma to extract the data/remove lock files:
I can't do that because there is no custom recovery installed on the phone. Just the stock.
3. Installing a custom recovery:
I can't install/flash anything on the phone because the developer options, usb debugging & bootloader are not unlocked/enabled.
I came as far as being able to see my dive with adb on my pc, but I couldn't flash anything of it, because the signature fails.
I'm now posting this threar, to see if anybody has some advice for me, how I could get the pictures from the phone.
Thank you all in advance~

The door to any Android device is ADB.
You say

hence ADB obviously is fullly working, means it should be possible to pull out the data in question by means of ADB.
Hi, thank you for your answer, I have expressed myself wrong/mixed adb & fastboot up. What I wanted to say, is that I can see the device via fastboot. Unfortunately not over adb.

as you can also see in the screen
If I understood what I read, there is no way to access the phone like this, is that correct?
Is there anything else I can do?
The Phone itself gives me an option to "Apply Update from ADB". My knowledge about this stuff is barely anything. But is there a way for example I could install/update an android version/new system without losing the internal data? At that point I don't care about the phone working properly, as I would like to get the pictures from it & root + wipe everything from it.
push
As "Apply Update from ADB" implies this option is used to flash an OS's update provided by OEM/carrier: updating an OS doesn't affect user data stored on phone.
Have you ever tried to exit phone's fastboot mode by running Fastboot commands
Code:
fastboot devices
fastboot reboot
I ended up factory resetting the phone. This Thread can be closed
If you have usb debugging on. Then you can use ADB. You can try to mount user partition and you can copy that partition.

Can recover data/restore factory rom via adb/fastboot/PC only (w bootloader locked)?

in brief:
the data should be there on the phone, so there's hope it should be easier to recover than deleted data but i run out of ideas how to get adb to find and pull it... maybe a more advanced user has better knowledge (better commands or tools)
adb devices and fastboot devices communicate with phone, so i have all drivers installed, i can only tackle with it via usb from windows 7 based computer
the detailed story:
i have a huawei g620s-L01, stuck in bootloop (just loading huawei logo forever or until battery empty but does not restart) and also "volume down" button does nothing... the bootloader is locked and huawei seems to have stopped providing unlock codes...the touch works but is shattered so i was told repair the button is not an option...
i can boot it into recovery mode using "volume up + power" but i can't use the recovery menu due to the dead "volume down"
from recovery menu i can only "reboot system now" but that re-enters the bootloop,
also i get bootloop if i try to boot into download mode via adb command
i can use some adb commands (i say some because some return errors, others say i don't have permissions)
i can boot into fastboot via adb command too...i can not find my dcim folder or any data folder to use the pull commnad, i tried the generic commands to pull sdcrd or dcim or all files with *.jpg
the user data is not accesible, i could browse some system directories but they did not contain my files via cd commands
i found some threads saying maybe i need mount or root commands
but trying to mount partitions or access su via adb also gives errors
su is not found, i do remember there was a su when android was working on the devices but is useless if i can't find/access it
i found the factory rom and some tools to try to restore rom to the phone due to claims that same rom might find my data, but the tools failed to start due to locked bootloader
i also tried several versions of full android sdk (old and new) trying to find "monitor or file browser" tools but the menu is not there...perhaps it will not activate those tools when device is in fastboot/recovery modes

}
i also found a 3rd party full android browser but can't connect with it either
also recovery softs are useless, they need a working android to try to recover anything...some recovery softs claimed they can fix bootloop but don't support my device
free tools that try to unlock bootloader also failed
so at this point i am running out of things to try
this is what i figured so far: i can see my data but can't touch it
i seem to have 4 partitions on the device:
1 is called sdcard but has nothing accesible on it, could be the feature for external card
2 is called ext , total size is 711,49mb , used 124,98 and available 586,5
3 is called system , total size 1,64 gb, used 1,23gb, available 418,1mb
4 is called data, total size 3,96gb, used 3,75gb, available 218,16mb
clearly the data partition is still keeping my data
i can not see my installed apps, so i guess they are also on that partition
i can see some system apps, namely 49 out of 146
so i'm guessing the issue is with one application, likely system app since i can't see them all
the phone may be partly rooted, the android may have some rooted features but the adb on it is not rooted
so i can not use the adb root command to get to my data
and i can not try to flash recovery or rom or custom boot img from adb due to bootloader locked and asking for unknown code

[Help] Why does my phone's boot screen look like this?

I got a pixel4a phone, but the startup screen looks like a factory mode screen. how can i remove this screen, thanks a lot

that's not a lot of info to go by. what did you do prior to getting this screen? since when has this screen been showing? is it rooted? did you do low level stuff with it, and if so, did you do it through a computer or on the phone directly?
the first thing you would want to do is to check if you can enter recovery mode (stock will do if you don't have an aftermarket) and see if you can do something with that, like, say; factory reset.
the next thing you could try is to first backup your flash, and I mean from sector 0 to EOF, and a second backup per partition, then flash a stock rom you could get online.
I WOULD preffer to just diagnose the problem and fix it non-destructively but phones and their OSes are not built to accomodate repair beyond changing the screen/batery and resetting/flasing the ROM
P.S. throw in the chipset type while you're at it I.E. MTK or QLM
Thank you for your response, bro! This phone is a second-hand phone. When I received it, it only had the factory mode. I flashed Android 11 through the website flash.android.com, but every time I boot up the phone, the screen will display for a few seconds before entering the system. I searched online and it seems that the phone is still in factory mode and needs to be activated to normal mode, but I haven't found a way to switch to normal mode.
1. Enable ADB ( AKA USB Debugging ) on phone
2. Connect computer and phone via USB-cable
3. On computer run ADB command
Code:
adb reboot

well, taht just sounds like the ROM didn't come with a boot animation/logo so I suggest if you want one you can well... there's not much you can do without tripping tamper triggers I.E. install rootkit & modify system partition (can't be done post pie) or unpack system image, insert the animation/logo and repack, but then you have an orange state device and that's not much better than that factory logo, or you lock it without image verification enabled and hope that something doesn't rely on it
android isn't built to be moded, so you have to mod it before building an hoo boy is that a wild ride
P.S. on second read, the ROM might be in eng mode instead of userdebug or user
you could check it by either terminal emulator, issueing the command `getprop` and search for build variant or do so through adb
