Mytouch keeps going back to fastboot screen

Hello, I recently got a mytouch3g from my friend and it is stuck on the screen with the 3 androids at the bottom. I think this screen comes up when pressing vol down and power. Well, I tried to reload the factory firmware using the sappimg.nbh file, and it said OK for all the steps, but it just keeps going back to the white screen with the 3 androids. Any help please?

This might sound like a stupid suggestion, but have you checked if your volume down button is stuck? If so, every time you press the power button, its going to take you to the fastboot screen.

Lmao. Thanks. I did check that, but it is not stuck. The problem is I dont even know if someone tried to root it or not. It just keeps going back to that screen.

If its rooted, more than likely it will have a recovery image such as CM-Recovery 1.4 or RA_recovery 1.5.2, etc. Try powering down, then press home + power button for a couple seconds and release.

Thanks for the reply. I tried what you said but it goes back to the same white screen with 3 green androids at the bottom. I dont even want this rooted. Just back to normal.

[Q] Boot up screen

I installed Euro firmware, on the second flash everything just stay'ed black, and I waited awhile till I decided to power off then power back on. First thing I saw was AT&T connect boot screen, then it went black but I can still hear Samsung's power up theme, also device has a Vertical Line running down the right side. I noticed that If I press power button twice Tab comes on, and everything looks great, so I rooted my device and installed Titanium Backup,Everything seems okay. So my question is how do I get rid of the AT&T Boot logo and to be able to see Samsung logo on boot?
\\\\\\\Exactly what happens on fresh boot/////
-fresh boot- AT&T Connected screen comes up, then screen goes black with the line on the right, then Samsung's power up theme song comes on buttons light up screen stays black line goes away, then screen still black, then to initialize the screen I press power button twice. Comes on and works fine.
****Would love to fix that part, I would be most greatfull for life! Willing to pass on info, to all who want more!****

Install euro firmware with bootloaders. JJ4 is good one since it's bootloader is not signed. Then you can install newer euro firmware over it.
However, so far there is no known way to go back to AT&T bootloaders. So you ca't fully restore to AT&T if needed.

Wait a little to make sure its not just taking a while to turn on. Then just hold power button and once it shuts off quickly press power and volume buttons to get into boot loader before it reboots. From there plug it in and use the toolkit to restore to stock (this will wipe everything on the tablet even data). Or you could go into recovery and just do a full wipe. I think it should then turn on fine but again youll lose data. Try the second way first as its faster. If it doesn't work then try the first option.

I am having the exact same problem. I tried the toolkit, but nothing happened. It seems that this is a strong brick.

[Q] Bricked D800 after flashing 'boot animation'

Well, I finally bricked my first phone since starting with the Dream way back when.
I was flashing different boot animations on this D800 and came across one supposedly for T-Mobile. I had unlocked the phone, and changed from AT&T to TMO, so I thought it'd be appropriate. Boy was I wrong.
As soon as TWRP flashed that ZIP and rebooted, the screen went black. No LG logo. No animation, no sound, no nothing. So I looked into the ZIP file I downloaded (from somewhere on XDA, I'll have to find the thread) and it looks like a full TMO ROM. Great!
Now I can't even turn off the phone. I can see the backlight on the (black) screen, and when I press and hold power, it restarts after 10 seconds, but then comes back on. Something else strange is that a drive F: shows up on my PC, with about 70 MB of various files. Then there are about 10 other volumes, G: through T:, but they are empty.
Now what?

Have you tried to get into recovery using power+down? If so, how about download mode?

Yeah, I had just made a backup in TWRP, so my first thought was get back into recovery. However, Power+Vol Down doesn't do anything except reboot, just as it does when holding only the power button. Same thing with Power+Vol Up and holding all 3 buttons down.

You need to keep holding until the LG Logo comes back, then release and hold the buttons again :good:

Yeah, I have tried holding them down for multiple reboots but it's all black, every time. I haven't seen the LG logo come back up since I flashed that ROM. I've tried letting up on the Power+Vol Down button at various times to try to trigger it and I can't figure any way to get into recovery.

try this solution. It may help:

I assume you've tried shutting down completely first?

The multiple drives is good, you can resolve this. In not near my computer now but try looking for a thread about no recovery no download mode etc, in that thread it is suggested to connect phone with usb while running ubuntu.
I used that thread to revive my phone after a bad flash.
Keep in mind that the files mentioned there are maybe not for your model so you will have to find the correct files.

When I get a black screen after flashing a boot animation and the phone does not boot (just gives a black screen) I usually remove the boot animation via adb. This will use the generic Android boot animation and boot your phone up

Well, I don't think this was a boot animation, even though it was advertised as such. I wasn't thinking, because I know better than to accept a 798MB file as being just animation, no matter how elaborate. I mean, I've been doing this since 2008, but I flashed it anyway. Only after it blew up in my face did I look inside the ZIP and see all the stuff you'd have for a full-blown ROM. Ugh.
In any event, I don't have any adb shell or devices or anything when it boots, just those weird drives.
The real kicker is. this is my 2nd G2 -- the first one having gone into some kind of CPU thermal runaway. I had to send it to Samsung in TX and they replaced the system board. So I've "used" this phone, which I first bought December 5th, for only about 3 weeks total at this point.

I eventually figured out that I can get it to turn it off, by continuing to hold the power button, At first it will reboot, but after a few more seconds it turns it off. Or what looks like off -- nothing is ever drawn on the screen at this point, not even the LG logo. So I basically have to hold the phone up to my eye and watch for the backlight to be on or off.
I also left it "off" overnight, but it didn't help.

I just read your post saying that you had flashed an entire ROM. Do you have a ROM backup you can restore?
D803 up in this *****

Have you tried while it's powered off to turn it on and plugging in the usb cable(connected to pc of course) to see if it enters download mode(just incase I myself have never been able to access download mode using the button combination on the g2), if it enters download mode all you would need is the LG flash tool and a tot of the d800 to get back to stock?

Yeah, I was going to mention this. Once you have it completely powered down, hold volume up and plug it into your pc. That should throw you into download mode where you can restore through lg flashtool.
Alternatively, while powered down completely, you can attempt to boot into recovery by pressing and holding volume down and power, hopefully the lg logo will appear again, and you can release and press both again. I've been in situations where it took me a bit, meaning multiple tries and a few dirty pairs of underwear, to get it to work. But it eventually did. Admittedly, none of these instances occurred after flashing a rom for a different device, so your mileage may vary.

Samsung S4 stuck on first logo screen

I only use my S4 to listen to Spotify and Podcast, no other apps are present. I use it until I the replacement Headphone thingy comes for my Nexus 5x.
It's my old phone and it worked great until yesterday when my screen went completely pink and then my phone restarted. Now it's stuck on the first logo screen.
Not the Samsung animated logo screen, but the very first completely white text Samsung Galaxy S4 logo, I can't post pictures.
I am using a Cyanogenmod Rom because of the memory leak bug on stock rom.
I can't boot to recovery because it just boots for few seconds, then shuts off, vibrates 2 times and goes back into the boot screen where it's stuck.
The vibration thing happens everytime I try to boot the phone. The logo comes up, it shuts down, vibrates twice and then it gets stuck on the logo indefinitely.
I can boot to Download Mode and I can't boot to Safe Mode.
Any ideas what I could do? I really want to listen to stuff again.

Could be a power button issue. Open the phone, clean the power button contacts with a bit of pure alcohol, quickly press and release the power button several times in a row using a bit more pressure than usual, reassemble the phone, and see if it works.

It's still stuck the same way.

When I got to the Recovery Screen once, the screen turned yellow and phone restarted.

The power button may need to be replaced. Do you have a multimeter to test the connections?

@audit13: I've got a feeling the power button isn't his issue. On a properly working S4 the screen wouldn't flash a particular color before rebooting. Given that this happened to him suddenly, I think he has an issue with the SoC itself.

I have a almost dead S4 i9515 model here, it stopped working.
Here at home I plugged it in and it vibrated continue and nothing more.
Tried a couple of times to go to recovery (unrooted, so the standard recovery) and one time I got a Samsung logo with something blue in the top left side of the screen and nothing else.
Cleaned the power button and started the phone and got the Samsung boot logo, but it got stuck in the logo loop.
How can I check the power button with a multimeter? Is there a trick to get to the connectors?

You need to remove the back frame to access the power button connectors. There should be there of them. Without the power button pressed, touch the probe across the outer two and see if there is any current being passed.

Will try it this weekend, if it is the button I will just take it out, and try it that way till I get a new button.
Thanks for the tip!

Well, the button was not the problem, see next post

While starting it won't pass the Samsung logo boot,
while starting via recovery (power, home vol-up) I still won't pass the Samsung logo screen, but now with the message in the top left screen 'Recovery Booting...'

It's dead I believe, the power button is okay, but after a few difficult boots, it wouldn't pass the Samsung logo.
But now it doesn't respond at all anymore.
Is there a way to access this phone?
Via adb or Odin? I don't think so, if the phone doesn't startup I can't do anything...?
It is bye S4 I guess...

I am blocked here too with a GT-I9506, and can't fin anything, so yeah, i guess it's dead, mine too

Time for something new...

Anyone managed to revive his I9506? I have similar problem, if you can guys look into it and tell me that you have tried this already:

I think it will be the best way. It's third day of flashing stock firmware from 4.3 to 5.0.1 NEE an TPL. There ware two times that phone actually booted to recovery and green android appeared. But then phone rebooted and still can't get up.
