[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

How do you get into download mode?

I'm holding volume down and power. I hear the jingle but it just stays on the "Vibrant" screen... Ugh. My phone is brokedy broke.

Are you rooted?

I rooted with RyanZa's OCLF but unrooted right before doing the recent OTA update. After doing that, my phone wouldn't boot past the Vibrant screen. So now, I'm trying to get in download mode so I can use Odin to get back to stock. Nothing is working for me right now though.

Ok, I was going to tell you the easiest way to get into download mode, but your phone has to be on. It is still possible if you know how to use ADB and your phone was in debug mode.
Also, how long did you wait on the Vibrant screen before restarting it? It can take awhile. Did you have any lag fixes installed?

the best and easiest way i have found to get in to download mode is this.
1. remove batt.
2.plug usb into computer
3.put batt. in
4.hold volume down+up
5. plug usb into phone.
if you need more help with getting your phone up and running, feel free to PM me cuz i just went through this my self, i know how confusing it can get.

I had done RyanZa's lag fix but I also undid that before doing the OTA update. My phone was in debug mode, but unfortunately I don't know how to use ADB. I waited a while on the Vibrant screen but I'll try it again in case I really didn't wait long enough.
Btw, thanks for the continued assistance.

Yea.
Try this also:
Plug in your phone til you see the big battery charging icon
hold down both volume keys and power.
As soon as the battery goes away, release the power key but continue to hold volumes.. Try that..

You are essentially holding down the wrong buttons...
There after two "modes" your phone can be put into...
1. Download mode:
Done by having your phone off and then quickly turning it on and holding down JUST the up and down volume controls while having the usb already plugged in (easist I've found is stated above regarding taking the battery out, plug in usb, hold both volume buttons, then while holding them put battery back in)
2. Recovery mode:
Done by holding both up and down volume buttons AND the power button. (note: after the vibrant screen comes up, release only the power button while still holding volume buttons or else the vibrant screen will just reboot over and over)

Thanks all, I realized that I didn't have the right drivers installed. (duh). Thanks goes out to those who pointed me in the right direction.
The new problem I have came after accidentally pulling the USB cord out of my laptop while running ODIN. Now, all I get when trying to get in download mode is a graphic of a phone, a yellow triangle with exclamation mark, and a computer.
Anyone know what do do?

Replacement Galaxy Tab?

Someone gave me their Galaxy Tab yesterday and said, "Here. If you can fix it, it's yours" The only background I have is one day it charged and turned on like normal, then it just stopped.
I've already done all the known fixes such as holding the power and volume buttons for a REALLY long time in all the known configurations. No luck. I took it apart and there's no signs of physical damage. I only have a wall charger so I don't know if my PC will detect it or not.
Is it possible to get a replacement from Samsung? I have no idea what warranty is on it (I'm sure none) but I know there are often still ways of getting replacement stuff from companies. Any suggestions?

I was in the same situation and I tried the following.
Plug Tab into the USB port on your computer, and make sure your have the Samsung drivers installed.
Hold power button for 30 seconds and release.
Now hold down the power button and vol down button for 30 secs and release.
Now hold the power button again and this should put you into fastboot.
Hit vol down then vol up. If tab is rooted, it should go into clockwork, if not, it will take you into Samsung restore.
Select factory reset.
Once completed, the tab should power up.
It took me about 4 tried to get this to work so I can't guarantee it will work for you, but just offering my 2 cents.

Thanks! I will try that. I don't have a USB cord for this Tab. It appears to only have a wall adapter. Do you know where I can track one down easily?
EDIT: I'll just order one via Amazon and try this out once it arrives

crap, I just realized I posted this in the wrong forum. I have the regular Galaxy Tab, not the 10.1. Mods...

How do you put SATV into fastboot/recovery using the power button?

Anyone have a link to a video showing how to use the power button to put this thing into fastboot/recovery?
I have a unresponsive unit that I want to flash. Seems like I can't get it into recovery but I'm not sure if I'm doing it correctly.
Here are my steps:
- Unplug everything from shield and unplug power from wall
- Plug in USB OTG cable from computer to shield tv (no lights from shield at this point)
- Plug in power cable to shield tv (power still unplugged from wall, no change to shield)
- Hold power button on shield tv for 3 seconds (nothing happens on shield, no lights or indication)
- Let go of power button and plug in power adapter to wall (light on shield turns on at this point)
- Nothing happens, no HDMI output and no indication from PC that a device is connected.
Any help?
FYI from nVidia website:
Code:
HW method:
- Disconnect power cable
- Insert USB OTG cable and make sure to connect other end to a host PC
- Connect power cable to SHIELD
- Quickly start pressing power button for ~3 seconds
- Do not hold the button and connect power supply afterwards
- HDMI TV should be always connected to SHIELD

I've booted mine over 100 times and only got in to work once, and can't reproduce the results. I have posted a similar thread, and couldn't find anything, but I'm terrified of something causing an unbootable device again because of this reason. If I find anything else to help out, I'll let you know, but my best advice is just keep trying, a lot. Don't quote me here, bit I think when I got it to boot sucessfully, I wasn't holding the button, I was tapping it for 3 seconds. Fairly quickly, but not super fast tapping. Some users report holding it works, but that didn't seem to for me.

Its a ***** to do with the hardware buttons but I have done it when I had a bootloop. If you can get it to boot normally its far easier to do it via adb "adb reboot bootloader". And if your rooted you can just use a sideloaded reboot manager app.

Yes doing it with a rebooting app or by connecting to a computer is the way to go.

It's not responding, so they basically need to recover a soft brick, which is why I'm going to assume that they posted here. Someone needs to figure out a better trick, or they need a better method for any successor to this. Especially since it supports fastboot oem unlock.

i hope nvidia put a timer trick or something to boot it in recovery mode ,maybie hold the button some secs.
maybie you will find some info in the shield documentation?
edit:found something i guess :
HW method:
- Disconnect power cable
- Insert USB OTG cable and make sure to connect other end to a host PC
- Connect power cable to SHIELD
- Quickly start pressing power button for ~3 seconds
- Do not hold the button and connect power supply afterwards
- HDMI TV should be always connected to SHIELD
Alternative method:
- Perform software shutdown on SHIELD by holding Power button for 10 seconds
- Connect USB OTG cable to SHIELD
- Start pressing power button for 3 seconds
- HDMI TV should be always connected to SHIELD
then you can use nvidia full recovery images to flash the shield to factory firmware.

Been through it all. Soft bricked my shield, and spent an hour trying that. Only got it to work once and stopped playing with it.

I got it to work with the hardware (plugging in the power cable) method as mine was in a bootloop. I found it difficult because it hard to know exactly where the power button was because its not a raised button. Once I figured out the specific location of the power button I could do it reasonably consistently, like 1 in every 3 attempts. Of course your device may just be faulty unfortunately.

Correct me if I'm wrong, but the power button is the whole thing. If I touch anywhere on the button at all, it'll put my shield to sleep, or wake it. That being said, I could have a faulty device as you have stated. I'd really like someone to put a video on youtube of a sucessfull run just to try to match it as close as possible, because 1/. runs is much better than my 1/100 or so runs.

No,it is just the nvidia logo,it is written in the manual and on the plastic cover when you un box it.

A user from another german forum got the right trick for timing, so it should work nearly every time to enter the bootloader :

If you want only to test how to enter the bootloader, it's not mandantory atm.

- Now WAIT for ~2 seconds

Just count: 21...22.. if you don't know how long are ~2 seconds

Is there a visual cue for holding for 6 seconds? I noticed the NVIDIA splash screen appears right around 2.5-3 seconds, is that too late or right when I should begin holding power?

What worked for me was letting the unit sit unplugged WITHOUT the OTG cable for about 10 or 15 minutes. I then prepared myself to plug the ac adapter back in and almost immediately pressing the 'on' button thereafter. Got to the bootloader and was able to recover from there.

According to the Nvidia Shield information page, you plug the computer into the Shield's micro usb. Unplug the Shield's power. Wait like 10 seconds or so. Plug it back in. As soon as you see the light come on, wait for about 2 secs. Then hold down the power button till the bootloader comes up. It should come up within 6 secs, maybe sooner. That's it. Basically like what scorpio16v quoted. What Nvidia doesn't tell you, is that it doesn't have to be plugged into your computer. For example, I was able to get my Shield TV to bootloader using this built in hardware method by plugging it into my OG Shield via otg adapter on the micro usb cable.

Saw this on the Shield User Guide:
Reset Using NVIDIA Button on SHIELD
To access the fastboot menu:
1.
Turn off your SHIELD.
2.
Unplug the power cable from your SHIELD..
3.
Connect your SHIELD to your PC/Mac/Linux machine's micro USB port.
4.
Plug the power cable back into your SHIELD.
5.
Wait 2 seconds, and then hold the NVIDIA button for 5-6 seconds until you see the fastboot menu on the display.
Here's a link to the guide

I don't know about fastboot but to reboot into Recovery, simply attach a USB keyboard and press ALT +PRINT SCREEN + i (same as the Ouya)

S7 Edge Dead

Hi guys, so I was flashing the FloydQ and once booted it asked me to put WiFi password. I did it but then it gave me black screen and the smartphone won't turn on no matter what I do and it was at 100% battery. I tried:
- Recovery combination (Home Button + Vol Up + Power)
- Fastboot combination (Home Button + Vol Down + Power)
- Connect it to the PC with windows
- Conncet it to the PC with Linux
- Tried to see if magically the ADB would find it
- Disconnect battery for hours
- Charging it the whole night (about 6 hours)
The result was always the same, absolutely nothing. I have also an USB Volt Meter and it take 5.10V and 0.23A that I think is reasonable because it has the battery at 100%. What can I do to try to revive it? Any suggestion?

Flashing a rom should not make any phone dead, your phone seems to be hard stuck simply, you need to hold vol down+home+power buttons to force reboot..
Read your rom's f.a.q, avoid any things/accessories which may cause compatibility issue..
If above fix doesn't work, hold power button while connecting phone to pc, or holding keys for download mode.
If still not work, you may need to use a usb jig i fear, but this shouldn't happen..

So I found this schematics and noticed that the phone get hot where the U7000 AP PMIC that is the power IC. It can be find online like S535 Power IC, already ordered and I hope to restore the phone. It couldn't be the ROM because I managed to boot it, and also trying like you said, nothing appear on my PC

Ah, really a bad luck/co-incidence to happen, a hardware fault at the same time after flashing a custom rom..
Maybe you should report it to the respective rom developer, who knows if there maybe a correlation between driver and wrong irq values and causing hardware damage ?
It is a known fact that samsung ufs chips can take millions of flashes, but its a fact too that an interrupted flash process or disconnecting cable in the middle of flashing when happens multiple times, can cause memory chip damage.
But all in all a phone board being killed by a wrong/incompatible driver is very unlikely.. you may just have been one of the unlucky ones, still report to the devs of your rom. Good luck

Hi,
I have the same issue with my S7. Did you fix this problem by replacing the U7000?

If its not yet solved after 2 years, my suggestion is to flash a stock rom in it.
STOCK ROMS FOR S7 EDGE
Just search your device model in the link, Download it and flash it using odin.
I hope it helps even if i'm 2 years late
