mt3g stuck at box-arrow-phone icon on power up

Hi,
I have a MT3G that my brother likes a lot, so he bought a second-hand MT3G on craigslist and asked me to help him make it work, since it is apparently broken.
On power-up it goes to a screen with an icon of a software box with a yellow arrow coming out of it and pointing down to a phone. Is this the "recovery screen" icon?
I put SAPPIMG.NBH on the root of a FAT formatted 2GB Kingston microSD card (the card works fine in my MT3G) and tried each of these key combos after removing and reinserting the battery:
hold voldown while click power = still the same logo and no progress bar
hold home while click power = same thing
hold back while click power = same thing
I also turned the 2GB card into a "gold card" using instructions on XDA and put on it the sappimg.zip that is supposed to fix perfectSPL. Re-did all key combos above. Same logo.
The only thing that results in something different is when I hold the trackball while powering on, and then I get a blue power light and blank screen.
Plugging the phone into the computer with USB with the power off and battery in shows the orange charging light, but the phone is never recognized as a USB device when it is powered on and connected.
Any help would be appreciated. I thoroughly searched the XDA boards and tried as much as I could. I don't think my brother can get his money back from the guy who sold it to him, and I have already yelled at him for not testing before he walked away with the phone.
Thanks!

the only thing I can think of not sure why right now this is only thing coming to me is while in the screen press home and back for a while or, hold some and power for alot longer even after the screen pops up just keep holding for at least a minute... another thing is hold home and power while inserting the battery.... also tell us what happens when you try to power the phone normally

Thanks so much for your ideas, mt3g
I tried home and back for a couple of minutes and still just stay stuck at the box-arrow-phone icon.
I then pulled the battery and held home and power for 2 minutes, and then released the power button but held the home for another 2 minutes, and then let go of home and waited another 5 minutes, but still stuck at box-arrow-phone icon.
Then I tried holding home and power while inserting the battery and it still stayed at the box-arrow-phone icon.
When I power the phone normally it still just comes up with the box-arrow-phone icon.
Any other ideas?
Thanks again.

Either a paperweight or a BRICK!!

your brother's been scammed... If you can't get into fastboot or recovery the device is considered bricked (well, not "techincally" as HTC could still fix it but you can't ). The guy apparently tried to flash an incompatible SPL (or something went wrong during the process) and then sold the brick...

the only way to fix this is to hold volume down when phone is turned off, then turn on the phone but keep holding volume down! this should boot it into fastboot mode, if it doesnt then its bricked.

Have you tried downloading the Android SDK and running adb devices while the phone is plugged in? You could possibly run a logcat as well and see what the phone is doing.

Thanks for the suggestions, Dixi789! No combination of buttons will get me to fastboot or any other screen than the one with the box-arrow-phone icon, and when I plug the phone into the computer via USB it is never recognized as a USB device, so the Android SDK tools don't see it as being connected.

Boot into TWRP... then follow my other directions.

From the op of KFU thread:
Known Tricks
•If you end up stuck at the yellow triangle, in KF Utility select Boot Normal, wait for it to say <waiting for device> and then press and hold the power button 20 seconds until the fire turns off, then when its off turn it back on. This sometimes happens, I have yet to find a clean solution
•If you end up stuck with a yellow triangle, do not EVER unplug it. Leave it plugged in. Check the windows drivers to make sure it isnt showing as "kindle" again. Fastboot is different and can cause this.
That fixed my issues in fastboot when I was trying to install TWRP the first time. If that doesn't work then [URL="http://forum.xda-developers.com/showpost.php?p=20945694&postcount=506]check out this post[/URL]

I cannot boot into TWRP because the kindle keeps shutting off because it is dead. It isn't read by the computer.

Plug it into electrical outlet and leave it alone for three hours.
While waitin for three hours assess your problem and find the solution. Search.
Then execute solution after fire is charged.

Will it charge even when it keeps turning on and off?

Yes it will keep charging.

It did not charge... At least I don't think it did..

When you plug it in do you get a solid color or is the light flashing?
When it's plugged in to the wall and the light is solid you should perform a hard reset by holding power for 20 seconds. This will fully shut down your KF and it will accept the charge

If by flashing you mean turning on and off by itself than yes, it is flashing.

Please help..I'm losing it
Same problem here. It does not seem to charge when plugged into either wall or computer. The green light flashes on and off repeatedly and the recovery screen (yellow triangle) just comes on and off (it eventually just goes black while the green power light continues to turn on and off)
in order to help myself I have done a few things
1: KFU isnt working.
I updated the drivers through KFU
I tried to change bootmode to "normal" and it hung on "waiting for device" I tried hard reset here and nada
2: I tried booting into normal fastboot 4000 through command prompt and hung on "waiting for device" tried reset..nada
So just like the poster above I cannot get into TWRP as the computer never truly recognizes the KF. This all happened when my wife turned on my kf and didnt know what the TWRP was and hit the power button for recovery. It loaded back to the stock kindle set (I had been using CM7) and since then I've been eating FUBAR soup as it doesnt work
Seriously..im pulling my hair out here...any help? I'd try to return the kf to Amazon and save myself the pain but I think we know what would happen when they plug it in and see the flashing triangle...lol

1. Plug your kindle in to the wall for 3 hours like someone mentioned previously (it will charge) The issue with the device being in a boot loop has nothing to do with the kindle fire not charging, this is perfectly normal if you have modified system files and the system can't boot the Android OS. It is also normal to never get past the Yellow Triangle if for some reason that you have changed to FastBoot mode. (Some people may be misinformed thinking that FastBoot does what it sounds like it does (boot fast - not the case), that's how this usually happens)
2. After you know the kindle has been charged for at least 3 hours on a known working power outlet. Press and hold the power button on the kindle for 20 seconds or longer until the device powers down completely.
3. Press the Power button to turn the kindle fire back on, and be ready, as it comes back on press the power button as soon as the Yellow Triangle (firefirefire) logo first appears. Press it up to 5 times rapidly. If you get to TWRP then you can relax. - If you get to the Yellow Triangle and you have pressed the Power button a few times but it is still stuck in a boot loop before giving up try one more time to shut down completely and reboot while pressing Power button rapidly.. You want to be sure to do this before the Yellow Triangle screen goes dim .
4. When you are in TWRP you should be able to use KFU or ADB. You may want to change the boot mode if it is not already to "Normal" if you are having this problem with "Normal" then try to reflash the Kindle with a recovery image or a new ROM.
Hopefully you can at least get to TWRP by following this, so that you can at least flash the kindle with a different update.zip. Good Luck

Charged like you said...still no charge. Flashes on and off and when you pull the power cord goes to black like its dead and will not turn on at all whether you hold it down or just push it...
Never had a problem like this before, could always at least get it to turn on or off not a mix of both lol. Thanks for the help...any more ideas on how to get it where I can at least get it into recovery?

I'm experiencing the same thing.

I'm still confused... are you guys trying to charge it while it is in the boot loop?
Have you tried turning it off (holding down the power button for 20-30 seconds until the screen and the power button go dark and stay dark)? And then plugging it in? I wouldn't expect you to see the firefirefire triangle if the device is off while charging.
The other thing that you might want to look into is the factory cable. Supposedly charges the device and can access it w/o any battery power at all - if I understand that thread correctly.

The point is you can't turn it off, it's dead. If you try to put it on charger either through wall charger or USB, it blinks on and off repeatedly and the power button does nothing at all. The computer won't recognize (tried several diff ports and pcs)
I'm beginning to think the factory cable is my only option to bypass the bootloop and fix it, just hoping I wouldn't have to wait so long for a cable or drop 40 bucks on it. I guess that's what I get for messing something up!

I left it bootlooping for like 6 hours on the charger. Unplug it and you can't turn it on. Plug it in and it bootloops and you can't turn it off. So is this just bricked for good with no possible fix?

Sorry. I was obviously hoping I was misinterpreting.

You may want to PM SkOrPn, http://forum.xda-developers.com/showpost.php?p=23024666&postcount=108, seems like he has them for $15/$19 depending on length (if your location is accurate.)

Kindle fire turning on and off by itself and won't charge
The only way I know around that problem is unfortunately to remove the back cover and remove the battery with a good adjustable power supply apply 3.7V to the battery for a 30 to 60sec it will draw approx. 3.4A and over the 30 - 60sec the current draw by the battery will drop. Be very careful as you don’t want to blow it up. Put the battery back in and you should find the kindle will charge again. Good luck

Hmmm, I wonder if the factory cable would be an alternative as last I checked an adjustable power supply (if you're without one) can run 70-100 bucks which is half of the kindle itself, I'd almost just take my chances sending it back in to amazon. Thanks for the help though from someone who has had the problem

Boot Logo Repeating

I have a galaxy s4 (i9500) and got it in used condition, a year ago. Never suspected a single problem in it.
Today I powered off my mobile for charging then after 25 minutes I took it off. I held the power button then I saw my boot logo(Where there is written Samsung Galaxy S4 GT-i9500). That logo kept showing as usual for 2 seconds and screen went black and again that logo appeared for 2 seconds and screen gone black and again it appeared, so, I'm stuck in kinda loop not a bootlooop exactly(maybe because bootloop refers to being stuck on boot screen while in my case its boot logo). I then removed the battery and inserted it back after an hour and as soon as I inserted it back the mobile itself turned on as if I held power button but this time again I was stuck in that loop. Moreover when I tried going into download mode, I didn't even need to hold the power button along with the volume down and home, it itself proceeded to confirmation screen of odin mode. And after that confirmation screen appeared saying that whether I really want to boot into download mode, disappeared itself after like 3 or 4 seconds even though I didn't press any key. And in case I press vol up key confirming to boot to download mode, then it again takes me to that loop. I'm too much confused . I can't even flash the firmware as it won;t boot to download mode neither am I able to boot into recovery.
Now do u really think the problem might be the power button(Which is maybe stuck in the state of pressed).
Or else it can be the battery coz my battery is also just average not too good?
I also inserted the command( in build.prop file) for enabling nav. bar and the code was correct but I never rebooted after inserting that. this was the first time I rebooted after that.
SOrry for some bad English.

Do you have something like this? I'm now having problem with getting my phone back to work...

From what you say it seams like power button problem, try to start the phone and connect it to the charger. When it start take out the battery, it will be powered by charger and you will eliminate battery problem.

Some help needed with my beloved Defy+

Hello,
As a newcomer to the forums, I'd like to ask for some help. I tried some of the methods described in several posts, to no avail. The situation is this:
Yesterday, I forgot my Defy+ on my desk and the alarm went of at 21:00 as programmed. It went for about 30 mins after that it was cancelled by default. I switched the wifi on and the phone restarted. In fact it stuck in a restart loop, mostly with the Motorola logo on screen. I took the battery out, kept it for like 30 mins, popped it back in and it went to the recovery console with the exclamation mark and the little droid icon. It stayed there for 30 sec, after that it went dark. Now this happened before so I did not panic and tried the battery swap again.
However, this time the phone is silent. Dead. If I plug it into a PC it gives me the notification sound (like when you pull out a usb drive from your PC) and the battery still gives out 3.7V.
No reaction for pressing the power button or volume up/down or any combination of that.
My question is: Is there a way to revive my beloved phone or is it just a piece of history now?
Additional info: Yes, it was a stock Defy+ with Android 2.3.4.
Any help is appreciated!

Update
Update: When I plug it into a PC with the Volume- button pressed down, a white LED starts to light until I disconnect it. During this if I try to enter bootloader mode, the PC recognises it as an unknown device and immediately prompts me to reconnect it.
Any ideas?

Bricked but not bricked?

So I bricked my phone a little while ago. I was flashing the deodexed and when it rebooted back to the bootloader I got nothing. Doesnt respond to anything. Well I was about to send it in to essential so I was taking the screen protector off and all that when I thought I saw a essential logo burnt into the screen.... Turns out its the Essential boot screen just SUPER light almost like a ghost or burnt image...
I can reset the phone over and over, it never responds to anything, no charge light from plugging it in, never appears as a port on my computer or anything... But I can watch the logo disappear and reappear by holding the power button for 10+ seconds...
Options to try to get to recovery/bootloader?
I have tried every combo of power, power vol+, power vol-, power vol+-, while unplugged, plugged into wall and plugged into laptop.... Tried all options holding for just 10secs and tried each one holding for 2 full min each to make sure I went passed the 45sec reset...
Not sure what else I can do.
Any ideas?
