[Q] Can´t access fastboot

Hi,
I rooted my N4 and instaled CWM and CM11 but after instaling gapps my GUI go complete crazy and turn black. I can ´t get to settings but I can start apps from lockscreen shortcuts. When i tried go to bootloader or fastboot it didnt work and I cant get to them in any way. So question is how can I reinstall the ROM or fix CMW? I tried to connect to ADB but whitout possibility to accest setting I cant get device found.
Thank you a lot
Can you boot your phone into the bootloader? And if so does your pc recognize the device? I'd the issue with your phone or the pc recognizing your phone?

No I cant get into bootloader or fastboot (power-vol) but system starts normally except i cant get into settings or applications menu because it crases instantly. My PC recognizes the phone and i can put files in phone. I have probably turn of USB debugging and cant find phone in ADB.
Thank you for response

Can you boot into recovery from your system, or does it crash too soon? If you can flash a nandroid backup

No basically I start to a system and have black screen. Only things I can start-up are apps on lockscreen shortcut and top panel (contacts,flashlight,GPS, calendar).
If your phone is booting normally and you can't access bootloader then either your buttons are broken or you're pressing it wrong.
Turn the phone off completely then hold both volume up and down together then continue to hold them while pressing power until it vibrates.
You were right Easyiest way is the best way! I disassembled the phone adapt the buttons and now it works perfect with bootloader etc.
Thanks for remind me other possibility

[Q] ZC520TL - Recover half-brick Zenfone Max 3

Hello to everyone,
I received a system notification this morning which was telling me that there was a new software update for the Zenfone 3 Max. So I've clicked on it to update the system, and, during the update, something went wrontg and it "crashed", rebooting in a strange korean (?) screen:
Now I can't boot properly the Zenfone and if I try to move inside the screen it just changes some english text from eMMC or FM to BT or GPS. It's like it is doing a device check and something isn't working.
It can't be turned off, so I just let the battery go dead to see if this would fix the issue.
I've charged it while it was switched off, and after a couple of minutes it turned on with the same korean (?) screen. I've also tried the hard reset by keeping pressed the power on button, but it only went off.
The last thing I've tried is to connect it via USB on my laptop while it is in this strange screen and checked that is recognised by the ADB. I've never unlocked the bootloader or ever rooted this model, so the response of the command "adb devices" is a model and the text "Unauthorized".
Is it something that I can actually do? I'd like to try an hard reset or force it to go in recovery mode and try to reinstall the firmware... but since the device is "unauthorized" I'm not sure that it will let me flash the firmware...
Do you have any advice on how to handle this situation?
Thanks in advance
(I do apologize for my grammar mistakes)
My English is really really bad, so try to understand this
Frst if ur phone is hang or stock in any ways u can reboot or power it off by pressing the power button for atleast 10 sec. Press and hold.
Second u can reinstall the firmware in any case even if ur phone is dead.
Frst u need to install the usb driver

Then u can reinstall the firmware using the following files
https://m.youtube.com/watch?list=PL4PNn1kmbOalk-kuEUO3hrJWA9hOAzl9Z&v=rh2m1Pgof2s and u need the latest firmware updates in zip.
U can get from here

First of all, thank you for the explanation, as far as I've searched this seems to be the "factory mode" screen of the asus zenfone max 3 with the chinese language setted... And the fact is that this mode is used for test purposes only, in fact if I randomly choose any option it just seems to test a random phone function. Anyway, I've tried to reboot it by choosing the 8th option, which is supposed to reboot the phone normally, and it kept on going in that screen again. I've also tried to reboot by forcing the reboot via (Vol Down + Power) buttons together.. and for my bad luck it still resets in this "factory mode".
I watched the video and not sure about it because I'm not familiar with SP Flash Tool: does my zenfone needs to have the bootloader unlocked? or it should have been rooted? Will I be able to flash the firmware while the phone is in the status, even if in ADB devices it is shown as "Unauthorized" ?
I'm asking all these questions because I've never done any firmware operations on this smartphone, I've only made ordinary system updates.
Thanks in advance for your patience and your attention!
Pressing volume down + power is going to that screen. I dont know if Chinese or Korean
Pressing volume up + power key for default recovery mode screen,
Press and hold the power key is for normal boot.
I dont know if zen3max need a bootloader unlock.
Because im able to install a custom recovery in my zen3max and my phone is rooted and im able to install back the stock recovery so i dont get any trouble Everytime i received a notification update.
Well if u r worried. Get another smartphone and use the google translator with the camera to translate that Chinese language on ur zenfone 3 max. Maybe u can find the format option or clear cache blah blah blah.

When you said that volume down + power key is the combo of keys to press to go in that screen... it kinda rang me a bell: recently my smartphone fell and it got damaged on the right edge, causing the volume down button to get inside the cover, and now it is like unpushable... I've never powered off my zenfone until I had to do this system update. So I thought that probably there isn't anything wrong with the firmware, it just keeps going in factory mode each time I try to power it on due to the fact that the volume down seems to be pressed all the time. So I decided to contact the ASUS support team to give it to them and let them repair the buttons.
Thanks for the info!
so must be thats the problem boot looping​ in to that screen because the volume down is broken. I guess.
Well thats the best u can do to fix it.

Screen black (broken) - How to recovery data (no usb-debug)

Hi all,
I have a particularly tricky case here. A OnePlus 3T with a broken screen (its black, can't tell if its registering taps) which I need to recovery data (photos) from. Normally I'd just use ADB but of course usb-debugging isn't enabled. I've tried rebooting into recovery... hold the power button and vol-down until the phone vibrates, keep holding for a few seconds. Then wait. Then vol down twice and power again to hopefully select English but the when I try
Code:
adb devices
nothing comes up on the list.
I'm wondering if anyone has any ideas how I can recover data/photos from this device.
One again the facts are:
-OnePlus 3T
-screen is broken, black, doesn't display anything
-usb-debugging is NOT enabled
-i can see the device in fastboot mode (boot w/ vol-up+power)
Thanks!
Maybe try a mouse with OTG. Would be horribly difficult i guess. But can probably work.
Also with any recovery, it would require your pin to enter the recovery (for decrypting the partitions); so that's a no go.
All you can try is to just boot the phone normally and try any input with an external mouse with OTG. Bring it to a point where the phone is powered on and unlocked so that you can copy data off the flash storage in MTP mode.
Ps: why don't you try to normally boot the phone and use fingerprint unlock?
did you trying with this link?

Using this tutorial in this case would make no sense, since the damage is physical and this way you're going to lose all the data currently stored on the phone.

if you have no usb-debugging and cannot see screen you are out of luck. same thing happen to me. the only thing that worked was I had twrp recovery and was able to boot into it. Recovery by default is in mtp so you will be able to see all your folders and transfer pics or backup files. last resort was to send it to oneplus repair which will cost about 100 bucks and you will get your phone back within 7 days remember to tell them to not reset phone because they will if you dont. good luck
You can also recover the data very easy through data recovery softwares. No usb-debugging and cannot see screen you are out of luck. I also have to face same problem the only thing that worked was I had twrp recovery and was able to boot into it.
You can try to flash TWRP in fastboot, then reboot recovery via fastboot command. MTP would work unless a pin is required in TWRP.
I can feel the situation,the phone doesn't work properly.

How to backup data on broken screen device

Hello !
I recently have an accident with my Samsung Galaxy J5 2017 (SM-J530) and now the screen is totally broken, he stay black.
But I think the phone is always working , because it vibrate when I force reboot with power and volume down buttons.
I would like to recover my datas because i didnt save them with my google and Samsung accounts.
I know that the USB debugging is enable and probably OEM unlock (not really sure, don't remember).
I tested ADB commands and the device is detected but unauthorized because I can't allow acces on the screen.
My phone is also detected by Odin in download mode and I know that we can use ADB in custom recovery like TWRP but to install it permanantly and see internal storage we need to do a format data.
If someone have a solution and can help me,
Thanks !

Flash twrp then try to go to it
And plug phone into your pc
Your internal storage will be there
To install twrp you don't need to format data btw!
The only thing that is needed to know is about oem luck to not f$uck up your device!
Thank you for your answer, I tried to flash TWRP with Odin and I didn't have any error.
After that, I rebooted in recovery mode and I can see my device on windows explorer but i see nothing, like when a device isn't unlock.
So I'm not sure if i am really in recovery mode, after flash in download mode I pushed Power + Home + Volume down buttons and just after that my device is disconect on Odin, I replace volume down by volume up.
If my OEM is lock, is Odin return error ? Otherwise how to know ?
Thanks (and excuse my bad english, i'm french...) !

Broken display, backup data / pictures?

My display is broken. I can't see anything on my Samsung Galaxy A40.
From the internal storage I would like to backup the pictures and videos.
USB Debugging is not activated.
When I turn it on it vibrates. So the phone seems to work.
But I can't see anything and therefore can't enter my PIN.
Is there any way to access the data without using the screen?
Is the bootloader unlocked?
Then you can fastboot boot twrp.img
And you should get a root shell to backup /sdcard folder

I have the same situation on my device. However I can't upload a new recovery image as the bootloader is not unlocked. Did you managed to recover your data somehow?

That's a big mistake my friend. Always remember first thing to do when you get a brand new device is to unlock that bootloader and enable USB debugging! It can come in very handy in such situations.
I'm afraid the only option for you is to look for a temp root shell PoC in the Sony cross device development section
Good luck!

This site shows the option to connect A40, if still Android 9.0, via usb hub to external screen and mouse and unlock. For Android >10 this doesn't work anymore
I have the same issue and neither usb-debugging on nor fastboot enabled. A40 doesn't show up in adb. So I also read when putting A40 via Power and Volume up into download/recovery mode, at least a backup of data should work.
My current idea is I have to replace display in repair shop or unlock via usb-hub + mouse.
Something I don't get right. How do you power off the A40 without screen to get safely the SIM card out? Power and volume down 7 sec, then release power off, then volume down? When I do this the A40 reboots with vibration. Power and volume up apparently reboots to recovery mode. Long pressing Power also doesn't turn off A40. Also in the A40 manual nothing is written on this
