Hello,
a friend of mine dropped his phone into water. However, I dried the phone as good as possible without opening it. Now when I start the phone it gets stucked at the Samsung Galaxy A40 secured by knox display. I let it for hours but nothing happens. When I restart the phone by holding volume down + power and after that I press power + volume up I can enter the recovery mode. Before I make any mistake I wanted to ask if I can get acces to the internal storage of the phone to get back the pictures and videos. May it help to wipe the cache? Or can I install any apk to get the phone connected to the computer?
Kind regards
Stefan from Germany

Has your phone screen cracked, leaving you unable to access your data? All is not lost! We'll show you various solutions on how to recover your data!
www.nextpit.com
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
I'm having a similar, but worse problem: a friend of mine let her A40 fall into the toilet at a party. When she came back home, the phone wasn't working anymore and the battery was swoolen. We've tried to dry the phone with the good old bag of rice for a week, then I dissassembled it to take out the battery and see if there was any damage inside.
While there is no visible damage, the phone doesn't give any sign of life, not even with the usb cable plugged in.
So I have two questions: is the A40 supposed to boot without a battery plugged in, just using the USB cable as a power source? In the worst case, is there a way to recover the data from the phone if it's not possible to boot it (I bet the answer to the last question is no)?

So, I've been trying to restore my phone after some modding gone bad...but now, I've gotten to the point where I can't even get to the green battery screen. My phone won't turn on, and it'll only display this screen with a phone icon connecting to a yellow triangle which is connecting to a computer.
Has anyone gotten this before?
More importantly, is this fixable? Or am I gonna have to file an insurance claim for a "phone that got dropped in a lake" this week?
Use the search option. It will do wonders. This has happened plenty of times before. ODIN can fix the problem.
1. Take out battery, put it back in. (to turn the phone fully off)
2. Don't turn it the phone on!
3. Plug the phone into your PC, do not hit the power button!
4. See if the phone shows anything on the screen
IF the phone screen does show the battery charger or something else on the screen after being plugged in without you hitting the power button, so far so good.
5. Now while it's on like this, hold the volume up and volume down buttons.
6. Hold the power button as well as the volume buttons until the screen goes black.
7. As soon as the screen goes black, let go of the power button! But DON'T let go of the volume buttons!

The best luck i had getting my phone into download mode was pulling the battery, putting it back in. holding vol up+down and plugging it in. instead of going to charging, it goes to download immediately.
All messages related to "3 hardware key combo to get back to download mode so that you can use ODIN to restore", or "use adb to get to download mode so you can use ODIN" only work when the 3 hardware key combo work in the first place, or your PC can recognize the phone for adb to work
I am one of the unlucky one that does not have this 3 hardware key combo working, and am also in this sad state (Phone-!-PC). As a result, PC is not seeing the phone, so adb is out of the question right now
My phone has been like this since last Thursday (a failed attempt to use ODIN to flash JAC's OC/Ext4 kernel). All my reading so far does not give me a fuzzy feeling that I can ever get back to Download mode (ON MY PHONE)
I called my carrier for a replacement, and it should arrive this morning...
If someone can actually get to download mode WITHOUT the 3 hardware key combo OR adb access, I would love to know how
Had the EXACT same problem. Here is how I fixed it:

Glad that this work for you
But not for me, for some unknown reason
No SIM
No SD Card
Pulled battery out
Make sure screen is off
Put battery in
Hold Volume up/down
plug USB cable to phone
plug USB cable to PC
Bam! Phone-!-PC
Update: Got my replacement phone.
Have SIM in
Have SD Card in
Leave Battery in
Turn off Phone
Hold Volume up/down
plug USB cable to phone
plug USB cable to PC
Instant Download mode!
Just as I read, it's a luck of the draw whether you have a TMobile Vibrant that has the 3 button key combo disabled. My first one doesn't have it. My second one does
Anyone having boot problems?
Waiting the case, i have put my tab in his box moving from a place to another, when i took it i saw a green andoid image with the message "POWER RESET or UNKNOWN UPLOAD MODE".
Now it is blocked in this message state. Can't turn off, reboot ...use it...
Anyone know the way to reboot (key combination)? if galaxy tab has a recovery system? or something in order to resolve this problem?
Just to know, no root attempts, only some application normal installed from the market...
hi, i think if you press the power button and leave it pressed, it will reboot.
after the battery charge finished and the recharged all work fine...
i think the "block state" has been caused from the home+volume keys that probably were were pressed in the box..
it would be usefull to know these key-press effects
They are standard android combos. Google is your friend.
I stumbled across this screen while my Samsung SGH-I897 (Captivate) was powered down, hooked up to my PC using the USB cable and the battery was half way charged. I held down both the power and volume up buttons for a few seconds and got to this screen before the unit attempted to boot. It remained there until I held down the same key sequence for about 5-7 seconds. It's now back to a powered off state, still hooked up to my PC via the USB cable, and the display has the standard large battery icon showing it at about 50% charged. Leaving the Captivate idle will continue to charge my phone via USB (abeit slower than having it attached to the power adapter) and the screen shuts itself off. It practically looks like it's fully off or fully dead like this, but it's not.
So few days ago my phone suddenly turned off and kept rebotting itself (It would reach the samsung galaxy logo and then turn off). I thought it was a battery issue so I removed it for 30mins and tried again, worked fine for an hour then problem started again. I left it over night to charge in the wall socket incase.
Same issue next morning and no solution.
I replaced the battery with a friends and the same issue happened on my phone (i used my battery on his and it works fine on his) so I removed the issue of battery itself.
That evening the phone then just stopped responding at all. It would not respond to pressing the power button (no load, no vibration).
Tried entering download mode using vol down + home + power. Nothing. (So cant use Odin)
Tried entering recovery mode using vol up + power. Nothing
Tried hard reset using vol up + power + home. Nothing.
(All the steps I used a fully charged battery from another s4 phone and removed/re-entered before trying again)
So I check online and notice some people having issues with power button, but even if that is the case - wouldn't my phone still charge? I dont even get the battery chargning icon on the screen when plugged in either PC or wall socket.
I opened it up and changed the motherboard with another samsung s4 and my original problem mobo still does not load on the new s4. (My new mobo worked on the old device though).
The ONLY response I got was when I used my original mobo on new s4 device and plugged it into PC, it popped connect and then disconnect sound and thats it (doesnt recognize usb port).
What are my options apart from getting another motherboard or going to a shop for a JTAG repair? I was contemplating just removing the power button and seeing if that helps in getting a charge response lol
Well your power button is broken for sure. Replace it and then test it.

Wouldn't the phone still recognize charging even if the power button is faulty?

It always takes a few seconds before it starts to charge. So maybe the device reboots before reaching the charging phase. I'm guessing though. But since your problems started with power button issues it would be the logic place to start.
The part only costs a few dollars.
Well I'm exactly in the same situation as you, since this morning on a i9505 running JFLTPE-GPE 5.0 ROM. The screen appears for 1 second or 2 (Samsung logo) then it powers off . I need to remove the battery to try something else.
Same behaviour, even for recovery mode, so Odin is not an option.
I thought that changing some kernel settings have caused that, but as I just put them back to default values, it should not happen.
I didn't have some power button issues, it was just powered off at my wake up this morning. In your case, does your phone vibrate and power up instantly when you put the battery ? That's the case for me, but it should not be the normal.
My problem is actually solved : indeed, it was the power button. I removed all the screws and played a little with this power button (air dust, etc...), enough to make it start correctly !
I managed to do some backups, and now I hope that it won't break again.

Yeah, that happened before (automatically powering up, vibrating, going to samsung logo and then shutting down and doing it again until I removed battery - putting the battery back in with start it up without pressing the power button).
When it was in that phase, the one thing that did work was doing a soft reset (home+power+down vol, and then holding just power) - however that only worked for like an hour before it went back to the restart phase.
However now it doesn't respond to anything at all. (Any kind of response I got was when I put that mobo in another s4 and plugged in usb, which just gave a connected/disconnect sound on w7, no life on the phone itself).
Be very careful as to what you do, I suggest you do NOT leave the battery on it and charge it (which was the last thing I did before it went unresponsive) - my guess is phone went haywire trying to turn on/off continously.
Hi! I managed to hard brick my galaxy s7 edge and i wanna see if someone here knows if its hard bricked or soft.
Got root and had renovate rom 2.0 ( n7 port) then i wiped my phone and flashed renovate 3.3 (s7 edge stock)
my phone worked fine on startup and i started to restore my old apps through gmail. i thought it would take a while so put my phone in my pocked and let it be fore about 20 minutes then when i took it up it was complete dead. i had about 67% before it died i tried everything (vol up down home all together) for at least 15+ sec. had it charge over the night ( i noticed that the phone didnt get warm or any leds shown) in the morning i tried everything again and nothing. when i connect my phone to my computer i hear the connect sound and then it disconnect a sec later. if i hold power button down and connect it ( and dont release power) my computer recognize it as onyx8890 and if i release powerbutton it disconnects. cant boot it in any way whatsoever. so what do you think? its only a week old thats the worst part of it!
I have left it to the store I bought it from for warrantable but its still rooted and have a rom on it. well if its complete dead they cant see if its rooted so thats one good thing.
still want to hear you opinion
sorry for bad english
so, from what I understand, u cant boot into any mode, are u even able to see something on screen? (logo, boot screen, etc.) U can try JIG (it somehow make any samsung device go to download mode). otherwise idk.
Hi guys, I have the same problem with my S7 Edge.
Can anyone help?
OK. So I managed to recover my phone.
The phone was dead because of a software crash(nothing on display, no LED light, power+vol. down for reset not working) and when connected to my PC - nothing (just a connect and after 1 sec. a disconnect sound).
But if I kept the power button pressed without letting go, my PC would detect the phone as exynos8890.
I tried to keep pressing the power+vol. down while connected to PC and I realized that the combo worked because after ~7 seconds the phone would disconnect and reconnect itself (but still as exynos8890).
But I tried a different approach. While connected to the PC I tried to keep on pressing power+vol. down. And I could hear that it disconnected and reconnected. But I did not let go of the buttons. And again a connect and disconnect. And again. And after literally 5 minutes of the buttons kept pressed down without letting go and countless reconnects there was finally a change. The disconnect sound was not heard after the connect sound. At that point I stopeed pressing the buttons and when I looked at the phone I could see that the battery icon appeared. Since the phone was connected to my PC, after 1 min. the battery started charging (it was charged 31%). And after that my phone booted fine.
wow
Hi I have just bought an s7 which turned out to be a Korean G930L but I cant get any response out if it apart from the 2 bottom leds and and the blue one. No response from trying to get into recovery or download mode, basically a black screen though it does vibrate on what i think is start up. It is found by pc and Odin and charges ok, I can tell as I can see properties on pc. But no other response. Is it possible that the previous owner tried to root it using non korean rom or TWRP? Any advice on how to fix either getting TWRP on or screen to light up. I am sorry for being so vague I have pulled it apart and checked all of the connections, screen, motherboard etc but nothing. Or chuck it out or put back on eBay. I tried your idea but it only booted once in that 5 minute period so I tried without it plugged in and rebooted several times but still no screen response.
Hello All,
Yesterday I dropped my phone and the power button got stuck. I opened the phone with my tools and was able to fix the button. I didn't power it off, I didn't think it was needed since the button itself has nothing to do with the electronics inside. While I was closing its back It suddenly turned off. I was very gentle, didn't do any fast or unsafe moves. Since then the phone shows no sign of life. I plugged the phone the my pc but there wasn't any sign of life either. The phone didn't show up on Device Manager or anywhere else. One time, I heard a connection sound but I am not even sure if it was because of the phone since the sound came like 5 minutes after I plugged in the phone.
I already tried pressing all 3 buttons for a long time but it didn't do anything.
So what do you think? What might have caused it? And can you help me?
Thanks
First thing i would do is tear down and disconect/conect the battery flat. After that, hold volume keys while conect to pc usb and see if you can get edl mode. Than flash all that has to be flashed with miflash and edltools.
