Today, when I was testing some application, that I develop, on my Z2 the phone freezes on a black screen after installing the app but still ON. the only thing that works was the shutdown/reboot screen when i press and hold the power key. So i reboot the phone but after the xperia logo and the boot screen logo, it freezes again and still on a black screen. i tried to do a soft reset by pressing and holding the little red button but that did nothing. My phone is on android v5.1.1 not rooted, I'm trying to find a solution for this problem without losing my data on the internal storage. I need your help please !!
Try to flash phone with flashtool and uncheck wipinig data in olptions before flashinfg.That sholud be enough.
Yh, exaclty what he said, thats the only way out
Thanks for the reply guys In fact I found another solution for that using ADB and I will explain it step by step :
First, I tried to copy all the data in the internal storage via ADB and I did it using the command line adb pull /sdcard/ C:\My_Data This method is only available when USB debugging mode is enabled.
Then, my second step was to do a hard reset and wipe all data and fix the problem but fortunately before doing that I thought to uninstall the application that caused all those problems, so simply I tried this command line adb shell pm list packages -f to list all installed packages in the phone and recognize the bad one then apply adb uninstall <package> Just after uninstall finished the phone returned to his normal state
*im not developer, neither noob i just like to share what I know*
Maybe this is a noob guide, but i did my best to share something helpful
before you go deeper, be sure to check your phone able to get into fastboot mode. If you cant, use REAL unbrick method instead
If your phone soft or hard bricked, bootloop, stuck on logo etc you know you are f***ed unless you know what should to do.
Some time ago bootlooped my phone, but i cant go to recovery, cant ADB because I forgot to enable USB debugging, my computer wont recognize my phone poperly because my phone mad at me, and my phone flickering like hell *party hard*. Maybe this is a brick not bootloop but whatever
Good friend of mine tell me what should to do
What you need:
Working PC with minimal ADB and fastboot installed //see the thread here, your phone's USB and ADB driver installed //download here if you dont have it
Working USB DATA cable
Custom recovery everything will do, as long as its compatible with your current android version. Rename the img to recovery.img
ROM you prefer everything will do, as long as its compatible with your current android version. Move to your SD Card
The power of will
Step:
1. Make sure your phone is turned off
2. Boot into fastboot mode, you will see some chinese message
3. Plug your phone to to your PC
4. Check if your PC at least know that you are pluged in your phone (check via device manager by 'plug and un-plug' your phone and check for 'appear and disappear' device , mine listed as it is was a modem.)
5. Move the recovery.img inside minimal adb and recovery folder root usually under c:/programfiles directory
6. Run the minimal adb and fastboot, check your device by using /adb devices/ command without backslash
7. If your device is not listed, dont worry. We still able to use the fastboot
8. Boot your phone into recovery mode by using /fastboot boot recovery.img/ command without backslash
9. Wait for few secs, and your phone should touched down to recovery mode.
10. Do wipe (data, dalvik, cache, system, internal)
11. Flash your prefered ROM
12. ..........???
13. Profit
Troubleshooting:
If your PC unable to recognize your phone completely, try using another usb cable, usb ports, uninstall-reinstall, plug-unplug, and make sure your phone in fastboot mode before you plug your phone to the PC.
Feel free to critics, I hope this helped you :fingers-crossed:
Thank you for all who helped me making this post.

You may need to check some things:
Your PC actually know that you have inserted your phone. It doesn't have to know it's a phone (so it can be detected as unknown device or something similar, mine is detected as a modem)
Your phone is indeed in fastboot mode, you can tell yours is in fastboot mode by a Chinese message at the bottom of the screen
Change your cable data, make sure it is a cable data, not a normal charging cable
let me know if you need some help

Hello. I Tried a lot, but my PC doesn't recognise my phone. The phone is in fastboot mode. I've tried by changing cables too
same issue

I am also getting the same issue tried different cables but not working. Anyone please help me
The same issue. I think it's about getting it recognized in Fastboot mode. It's recognized in Android but not in Fastboot. All new devices are installed including those you get in Diagnostic 9091 mode (Power+V+). What do I need for Fastboot mode?
Hello friends , I am that stupid who is locked out of my phone for last 20 hours. Apparently I attempted to unlock my phone with wrong finger, and now it's stuck on PIN unlock, which i don remember because I never really used it. Here's the detailes:
I want to recover some data, before factory reset.
Device Name: Le2 X526
(only integrated memory, no sd card)
Device state:
Fully Functional
USB Debugging - OFF
Bootlocker Unlocked
Fastboot Mode enabled
I have a valid fingerprint (if it can be used to unlock somehow)
Full access to my Google ID of my phone..
Methods tried so far:
- Web google interface to lock out phone, does not replace PIN password of my phone.
-No forgot password button after repeated attempts
-Cannot flash anything from pc, cause no usb debbuging.
Some hope from methods, Please help on these:
-In Recovery mode, i can flash a zip named update.zip from usb otg.
Please elaborate?
-Any method to reset back to fingerprint. After battery drain? Internet cut off? Anything?
-Recovering data after factory reset.
I have spent many hours into it. Will appreciate any help.
Peace
Any help?:highfive:
Which Recovery? TWRP or stock recovery? if u have twrp just go to File Manager - data/system/password.key delete this file and reboot ,now enter any random password and unlock ur phone
Where did you store your data? Because if you used an SD card, you can just take it off and insert it into a card reader.

Hello,
I have Samsung A5 2017, my cell has virus attack and every minute it restart automatically, all things are stocks so not able to reflash,reset device
is there any way usb debugging enabled from recovery/download mode ?
Not adb, but hold volume down while the phone is starting. A watermark will appear, "Safe Mode", the "virus", if not a root exploit, will not load and you could uninstall it. Also remove it from the device administrators & accessibility settings. If it doesn't work, hold volume up. If it doesn't work, press and hold the menu/recents key when the "SAMSUNG" logo and the brightness changes.

If you know your Google account details and you don't mind losing all your data reset your device.
It's unlikely it has compromised the system partition unless you were rooted.
If you were rooted then you may as well just wipe data with twrp.
Failing that reinstall the stock firmware.
nothing worked, i think virus at boot level, because can able to enter stock recovery, after factory reset result is same, tried with safe mode, but not work, not able to connect internet and reset device because it turn only 50 Seconds and rebooted, if i tried with odin than got error - FRP Lock, i also tried google device reset from web but it required internet connection on phone , so this option also not worked

If you have installed the correct firmware with odin and factory reset and your device still has issues then your problem is not related to a virus. More likely a hardware issue.

May be, but when i tried to install Custom Recovery CWM, TWRP it gaves message - custom binary blocked by frp lock
If i tried same firmware - then stuck without any reason - log say - recovery.img cancelled
why i think this is virus because i enabled usb debug and after auto reboot again its shows disabled , even i change wallpaper and reboot its showing same old wallpaper, means anything i do after 50 seconds revert back as it is, one kind device is locked

You can't install anything custom until OEM UNLOCK is enabled in settings.
Install the stock firmware with odin then factory reset in stock recovery.
You will need to enter your Google account details once the device has fully booted to disable FRP.

Yes, i tried , but not successes, after complete reboot i get 50 Seconds only, in this time period i can only enable usb debug, but when i enabled OEM unlock option, its automatically turn off without any error, and device reboot, so neither able to uninstall anything nor accessing via adb because 50 seconds its too less
even i connect with pc and try to format phone memory , after reboot all deleted file again available, even renamed files back to with same name

Forget about USB debugging it's not going to help you right now. I would try enabling OEM UNLOCK and then immediately power down the device BEFORE it reboots.

i tried OEM , but automatically turn off without giving any message, i connect with Samsung Kies, it show " Your Device is Locked" i don't no why this message came
is there any chance to do from Download mode ? because odin not work, i flash with PIT file but nothing has to be worked, because Samsung Official Lock enabled so we cant flash anything but is there any alternative of Odin may be work
I'm in a bit of a pickle right here. My friend's P20 Lite got dropped and now the screen is dead. Backlight turns on, but the LCD is really, really broken. I can boot it up and unlock it using his swipe-code (by guessing where the dots are), but I cannot recover his data, because USB debugging is disabled
If I reboot into fastboot mode (Power + Vol Down), I can indeed see it on my PC as a fastboot device, but I can't use that for anything, as far as I know.
If I reboot into recovery mode (Power + Vol Up), adb doesn't work.
If I turn it on, unlock it, and plug in a Type-C to HDMI dongle (with power), it does not mirror the screen onto the display. I know the dongle works, as I've tested it with several devices.
HiSuite detects the device is in recovery mode, but then continues to say the device is not supported for system recovery.
What other options do I have? I can plug in a keyboard after it's unlocked, so maybe it's possible to navigate it that way? Like "press KEY to access settings, press down key 20 times, press enter to enter menu" etc. etc. Unfortunately I don't have a P20 spare laying around, so I can't use that for guidance.
The phone's bootloader is NOT unlocked, so I can't even flash TWRP and get into adb that way.
Hopefully someone can help!

Hi,
Cloud you maybe help me too? Because I have nearly the same problem. I have a Huawei P20 with a broken screen, the touch does not work and I have a password and therefore I cannot unlock it, I would like to be able to get all the data back from the phone and I have tried in many ways how to do it without being able to use it and the only solution is do it through a computer, I have already tried to activate usb debugging with a program, only it shows me the notification but I can not approve, I checked if there was active ADB but it says it is unauthorized and now I wonder if I should send the phone in recovery mode or fastboot mode so that I can control it from a pc or somehow receive the data, the question is how can I do? I have no idea how fastboot or recovery mode can be and whether it will make me lose everything or not so I would like to make sure by asking an expert, I would be very grateful if you could help me.
Hi.
Do anyone has a solution to this ? I'm in the exact same situation...
- normal mode no adb devices
- fastboot mode works, but... what to do in it ?
- recovery mode, no adb devices, nothing
- download Mode too, "adb devices" list it, but unauthorized... Maybe there is a way to copy a custom thing through SD ?
Need help please :'(

When is see on the internet what Download Mode is for, i imagine it's possible to copy a custom firmware/OS on the SD card, and then, install it automatically by this special mode.
I just want to retrieve my data... The only viable solution for the moment, is to buy a new P20 Lite screen and change it...
