[Q] Unusual symbol: Phone -- ! -- Computer

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

[Q] POWER RESET or UNKNOWN UPLOAD MODE

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.

By the coincidence, is your batt serial no beginning with BD? If so, look on the battery. Is it swollen a bit? If so - call samsung, they will replace battery free of charge.
If not, try to connect phone to charger, insert battery, go to recovery and make full wipe.

it might be a power button issue

ok, this may be tricky.
while keeping volume down and home - slice battery in. If phone would boot in download mode (even just for a while) - then it will be power button issue.

it boots up on download mode for seconds and then powered off again....

Im digging up this post because this is the same problem i had.
I ended up removing the power button all together, carefully popped it off the motherboard. The phone no longer boots for a couple secs and powers off again so i think the power button was the issue. Now i have the problem of powering on the phone. I tried booting into download mode (to have the reboot option) by holding volume down+home while plugging it in but nothing happens, all i get is the battery charging icon. Ive been into download mode before i removed the button, but like the OP, it would only be a second or 2 before rebooting. Am i doing the correct procedure for download mode? Perhaps my timing is off? Any suggestions?
At least i do get the battery charge and it stays until i unplug the phone, no more boot loop!

Ok so i managed to get the phone to power up without going into download mode using this method i found on youtube. No boot loop and fully powered up now, the only thing is that im stuck on the lock screen. My friend cant remember his pin so i cant get in, the only option left now is to boot into recovery and do a factory reset yes? Well, how can i do that without a power button? Any suggestions?

[S7 edge]Cannot go to access download mode

My S7 edge often dies suddenly and everytime I need to restart or wait until it is out of battery to restart it. However today, unlike usual I couldn't restart my phone after waiting it out of battery. I even tried to hold volume down + home + power constantly in order to access to download mode, but nothing happened except a black screen.
I wonder do we have any way to fix this problem? Can a jig usb fix this problem?

Recover Data from Dropped Phone

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

How to use your broken smartphone from a PC | nextpit
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)?
