[Q] Brick? (Phone won't stay in download mode)

Hey guys, I'm not sure if my phone is dead. It was running fine this morning, Task & Ktoonsez' AOKP with Ktoonsez kernel. However, I tried to unlock it a little while ago and it wouldn't go on. It boots to the splash screen, both normally and going into recovery, but it doesn't last long enough to go into recovery or boot normally. I try to boot into download mode and it boots, but the phone turns off after a few seconds.
I tried to flash back to stock in Odin, but the phone doesn't stay in download mode long enough for the flash to finish.
I'm not sure what to do. Any help would be appreciated.

Pretty sure if it was bricked it wouldn't boot into download mode at all. It sounds like it is losing power or something. The only thing I can think of is maybe your battery is bad. Download mode can run off of USB power if you remove the battery after booting into it. Maybe plug your phone in and boot into download mode, then take your battery out before it shuts off and see if it stays on.

No dice. It just did the same thing it's been doing. I went into download, popped the battery, it stayed in download for a few seconds, and then powered off.
Could it be a faulty power button? The phone is constantly vibrating by itself and if the power button was messed up it could be causing the phone to leave download mode.

As far as I can tell pressing or holding the power button in download mode will only restart it, but won't shut it off. Also it takes about 10 seconds. I don't think it's your power button.

Ah, okay.
In that case, though, I have no clue what's causing the problem here. At this point the only thing I can do is enter download mode for a few seconds, but I can't get it to be enough time to flash a ROM in Odin.

Might be a dumb question... Is your battery charged? I'd plug it in for a while off and see if the battery logo comes up and than try putting it in recovery or download.

I tried that too. It's been plugged in for a while and the same thing happens. It just stays in download mode for a few seconds and then turns off. Also, I tried flashing back to stock in Odin but it failed because the phone turned off before the flash could finish. Now the phone says "Firmware upgrade encountered an issue. Please select Recovery mode in Kies and try again."
So it's basically stuck in download mode cause of a corrupted flash. If I could get the phone to stay in download mode, I could flash it back to stock with Odin, but it's not giving me enough time at this point.

I'm running into the same problem currently, I was wondering if you were able to find a solution. Same ROM same Kernel. I've been using my current version of the ROM since October and haven't flashed anything recently, It just died on me last nigth and now I'm experiencing what you are as well. I was able to turn on the phone somehow last night but it stayed on for couple of mins and turned off again. At the time I had 60% charge.
Thanks

Unfortunately not. Sent my phone back to AT&T and they honored the warranty (despite it being very clear that I was rooted and on custom software).

Thanks. I got the phone when it launched so it's been over a year hence I'm well over the one year manufacturer warranty. Doubt they'll honor it for me =/.

Bad news, It's not about software, it's a hardware issue.
I had that issue with a Sprint S3,
The power button switch is stuck pressed all the time, you can try to hit it a little and maybe it pops out but the issue is gonna still there.
If you remove and insert the battery does it vibrates and tries to turn on without pressing the power button?

yup I just realized it was the power button issue. I managed to fix the problem[kind of], i kept trying to get into download mode while connected to AC Adapter with official charging cables. And it stayed in download mode long enough for me to go back to stock ROM. I'm just trying to avoid hitting the power button as much as possible because every time I do something goes crazy and phone turns off.
I'm gonna try and go to AT&T store tomorrow to see if they can do anything about this.
Thanks again for your help. I really appreciate it.

You're welcome. Good luck dude :thumbup:

Power off completely, then hold volume up and power to get to bootloader. Press volume down until you get to recovery and hit power button. It should reset and then a android appears. If it then says error hold power and press up volume. You should get to recovery menu that way.
Wipe cache...
Reboot and see what happens...

Try tapping up volume 3 times but remember to let go of power at roughly the same time or 10 seconds later the phone will power off...

It just do not enter this recovery mode... no matter what

Mine is the same and won't boot up, just vibrates once and does nothing....

i resolved simply reflashing the old pre rooted firmware 2.19.40.18 and installing ota 2.19.40.20 with adb sideload after complete unroot with supersu.i forgot to uninstall xposed and this was the reason of my botloop after update to 2.19.40.20.luckily i had twrp so before reflashing i backupped all my stuff.that's it.you need to reflash droidboot,recovery,boot and system imgs from bootloader with the usually way.no other way out.hope you installed a custom recovery before loop,so you can backup

how did you do it ?
I have the same problem
---------- Post added at 12:33 AM ---------- Previous post was at 12:07 AM ----------
my device is in error screen, and with the dead robot.

Hi guys, please help, maybe some of you could do that for me... Problem is strange and I just did not find solution jet... So, I just can not power down my ZE551ML completly. Device is trying somehow to boot up, getting some kind of loop. First of all, phone came to me totaly dead - I have to plug it in to charger for 3-4 hours to ligh up notification led... After that it turned on normally. After first boot and setting things up, updates showed up. So I did update - for 4 times, OTA. It looks ok (now I have 2.20.40.90 clean, I mean no root or unlocked BL). But strange comes when I want to turn it off (power down) - device is shutting down, screean is going black and... bum! - the battery icon is showing up: emty for the very first few seconds, then it changeing to green (showing actually power state, I mean accu capacity), then device reboot itself and whole process starts over and over again... I can not stop it. Well, I think if the battery would be full, that could completly discharge it - couse is unstopable... I found, that when I press vol- when the battery is green, phone shuts off its screen, but after 20 seconds the process begins over again... i can boot it normally by pressing vol+ and power - it leads me to the bootloader manu, then boot normally - done. but it is very annoing... beside that phone is ok. Can someone help? BTW - I did factory reset from stock recovery, but it did not help...

I had the same problem. My solution was to unplug the usb charger. After that, the update was successfully.

on me Z007 I did a factory reset because my phone would not start and when it did it kept giving me messages about unfortunately this stopped and that stopped BBM, Zenui, google play store etc. Once i did the factory reset the phone worked again but I had no data so I thought I would just restart. Now all I get is ASUS and the spinning wheel. any suggestions??

Hello, I own model Asus Zenfone 2 laser 5.5 ( ZE550KL ) I have also same problem, phone keeps on rebooting....... Showing Asus logo and then vibrates and again start rebooting
I have installed asus firmware from SD card from recovery mode which was successfully installed .... did every thing after pressing volume and power button and even performed necessary actions by doing fastbood mode.
but phone is on same condition.... showed every where.. even service center people raised there hands
Kindly help me to recover my phone back.

Tablet won't turn on - HELP

Hi,
I can't get my tablet (G Pad 8.3) to turn on. It has TWRP recovery on it but there doesn't seem to be any life in the tablet to get into recovery.
I flashed fishears custom kernel and the tablet was working fine, I rebooted it and it started to loop and then just seemed to die on me.
I think I've tried download mode (both volume buttons) but can't get into that either.
I've tried the hold power button for 20 seconds then plug a charger in trick but nothing there either.
Before this happened the tablet had 50% battery so it wasn't really all that low.
Any ideas?
Thanks

hardbrick man, try fix http://http://forum.xda-developers.com/lg-g-pad-83/help/how-recovered-lg-g-pad-detected-t3207079

Hmm, I'm guessing my tablet has a hardware problem as it is not showing up at all in device manager.
I've got some tools coming tomorrow so I can open the tablet up, hoping a simple battery unplug might revive it! Hmm, I'm guessing my tablet has a hardware problem as it is not showing up at all in device manager.

Charge device all day, you try fix link up

I do not seem to be having any luck with this tablet. I re-installed the stock rom and now I am in an endless boot loop. The LG logo comes up and then the screen goes off then it comes back on again with the logo then off again. No amount of button pressing or sequences will load recovery.
I can't get the bloody thing in the download mode either. I'm holing both volume buttons then plugging in but it does nothing. I've tried volume up and power and nothing. Any ideas how can I sort this, as there is life in it it just won't respond to anything?
Thanks

infinite boot loop

Hey,
Yesterday I ran out of battery, when I got home I charged it.
After 15-20 mins or so, I tried turning it on, since then the phone is on an infinite loop.
It's displaying the lg logo, buttons are flashing and the home button changes colors.
If i unplug it from the charger it wont turn on at all.
It has cyanogen mode, not sure which version.
I've tried almost everything:
Removed the battery a million times, tried every button combination possible to enter recovery mode, connected it to my PC.
I have managed to get to the hard reset screen, pressed the power button twice to confirm, but still nothing happens and the infinite loop returns.
Any suggestions?
Thanks and sorry for my english.

Does it show charging screen or is just stuck on LG boot splash? Let it charge for a while, and then try booting without cable.

Nothing appearing over LG logo? Try booting with Power+Vol UP and release them and press Vol Down as soon as keys flash, I've managed to boot mine with broken battery that way.
Also, last resort - if you're sure your battery is 100% functioning, try entering download mode and reflashing.

a505fm bootlooping

I wanted to install a different rom, i have done it before, didnt quite remember how i did it so i followed a tutorial just to be safe. Followed the wrong tutorial, installed the wrong twrp recovery onto my A50 and i didnt untick autoreboot in Odin. Now its bootlooping, wont react to anything, cant power it off, cant go to download mode, cant go to recovery. Any time i plug it in, it will continue bootlooping. Any power source, it will continue bootlooping. When its on low battery it will turn off, but when i press the power button, it will continue for a few seconds. From this state it wont power on using vol down + pwr, wont power on using vol up + pwr, only the power button alone. I have tried anything i found, disconnected the battery for some time, nothing would help. I already lost hope, but someone on here might know whats up.
