[Q] Transformer not powering on?

Hey, I got my transformer yesterday, and for some reason this is the 2nd time this has happened, fully charged battery, but the device won't power on. Attempted to plug into power but no dice. Held the power button for 30 seconds, nothing, held the power and volume up and nothing. Yesterday when this happened I plugged it into my computer (Windows) and held the power and up buttons and it turned on though it could have been windows detecting the drivers. Anyone else having this? Any suggestions? I haven't had a chance to test again and see if I can bring it back through that trick yet, but I will. Then I'll try a factory reset and see if it resolves the issue. I would hate it if this is a defective unit, that's for sure esp since they are so backordered. Outside of that I love the device.

when your device isnt coming on, does your computer give you a usb notification? You could be putting it in apx mode on accident.

I will find out in a few. The thing is this has happened when I left the device unplugged and in sleep when driving to/from work. Yesterday plugging it back into the computer brought it to life. Nothing else did. Not sure what apx mode is even.

EDIT: Ok, turns out it get stuck in some weird power mode. I plugged it into the computer with no resolution, when I held the power button for 10 seconds, then waited 5 and pressed it again, the device powered on. I suspect it might be an issue involving detecting WiFi access points when driving or something else. I'll Factory Restore and see what happens.

try turning off screen lock.

I had that sometimes in the first day I had it, after that it hasn't happened. No factory reset, just make sure to do a hard shutdown (powerbutton 10 sec~) while it's booted and it should fix the issue.

Yea, it had happened once already, and again. I'll be testing today when I leave work, factory reset and see what happens. Should it continue, I'll go to the next step. I'm just not sure what it is. Interesting bug to say the least.

From the way you are describing getting it to work again, it sounds like you were in apx mode...

I still don't really know what APX mode is, from the limited things I have seen about it, in order to get into such, the device has to be powered off first. As far as I can tell, my device isn't randomly powering itself off and automatically going into APX mode. This happens without me touching the device. When I did the power off and on today, it wasn't plugged into the computer at all. There was no recognition from the computer that the device was plugged in.

Well as of today, my EEE Transformer is dead. Will not power on the screen, Asus offers a repair of 14 business days, unacceptable.

Powering on issue
Woah...I was scared to death when mine didn't turn on the next morning that I got the device. Charged it for an hour and try to turn on again, nothing.
Holding the buttons several different ways that I know how to reset it didn't work. Finally I held the button down for more than 10 seconds. Wait a few seconds, then it powered on. Why didn't they make a hard reset since you can't remove battery!??? Hope this is just some fluke and could be updated with firmware.

Alas, mine didn't get resolved with that, computer detects it now, but no screen response. Asus tells me 14 business days to fix then says try to restore it with the Kernel Source Code. Unfortunately I can't see a way to do such from the folder and they decided to disconnect me.

There is a bug with the default lock screen that makes it so the screen doesnt power on occasionally. In order to work around this you need to disable the lock screen in the settings, or change it from the default one.
Obviously in order to do this initially it needs to be powered on and so you can see it. Therein lies your problem of course. To get around this, charge up your device so you know it has power, use the force power off method (10-12 second press of the power button), wait a few seconds (30+), then power on the device normally (5-6 second press of the power button).
If your screen doesnt come on after that, try a couple more times. It really is an RMA job if it continues to fail. If it does come on, let it boot up to the lock screen, and dont let the screen go off, keep it 'alive', unlock the device and change the lock screen in the options, to either be switched off, or to anything other than default.
This wont work for everyone, as obviously a few may actually have duff screens, but for some of you, it may just be the lock screen bug you are getting unlucky with.

Yea, I seem to have not only the lock screen bug but a defective screen. Unacceptable to me, but hey, what can I do? I've been disconnected 5 times so far, waiting on a manager and will be requesting a faster resolution than what they are offering me. (10-14 Business days is unacceptable)

i am in the same boat as you, luckly i picked up the acer for the weekend because i didnt think i was going to get the asus. glad i did

I'm waiting on hold with Asus to see if they will do an Advance Repair, basically I get put on the line for the full price of the device until they declare mine broken since the return period on the Acer is 14 days at best buy. Quite outside of the repair period.

Had to escalate it up to management and expressed I wanted an advance repair and was willing to give them my credit card number so they could place a hold on the card for the amount of a replacement until they got mine. Has to be escalated above the rep should hear back in a couple hours. If not I have an extension and will call back

How To Unbrick Nexus S? Need Urgent Help.

Dear Geeks,
I need your urgent help/advice. i'm three weeks far to my wedding and have a lot of troubles to handle, of course i need this phone.
let me describe the matter i have.
My nexus s is not booting, not starting, nothing.
what i did?
Last night, power button stopped working. I have experienced this 4-5 months ago. I don't know why, the problem has been solved by itself after few days later. i did nothing at those days. the power button came back. (as to my opinion, this is happening due to software problem) Anyway, i have used the market and installed ''fix power button'' application to use volume buttons for opening the screen.
I slept and when i woke up, i saw that phone needs to be charged but i waited. there was %11 something. i tried to handle the power button, pressed many times on it, thought that it may come back again same as 4-5 months ago it happened.
I removed battery and replaced again. i tried this many times. removed, replaced, used the usb cable via AC charger and phone started but there was no result. power button still was not working.
i thought that if the battery runs out, and then, when i charge the phone, maybe this matter may be solved. (ok this was stupid idea)
phone started to charge. when i plug the usb cable, phone was booting and displaying the google and animation and later it was ok to use.
meanwhile i keep on removing battery and replacing battery while the usb cable connected. but when phone starts to boot, i removed battery and replaced again. phone was ok, it was booting. few times it was booting.
but baaaam.
it is now not starting not booting, nothing.
now, when i replace the battery, phone is getting hot, especially sim-card area. i m removing the battery and connecting the usb. same again phone is getting hot, same sim-card area again.
i have waited enough not to connect the battery or usb charging cable. but no result.
what can i do now? what are your opinions?
my opinions/guess:
-i am using 3500 mah lithium polymere battery. maybe the battery died. i m using that battery more than 1 year, around 15 months. i dont turn off wi-fi so i m charging phone everyday.
- phone crashed during booting. and now the phone is totally brick.(i dont wanna believe this, this phone can be usable, believe me i feel it i think whatever happens, this phone can be usable via software installing or rooting... of course if you dont throw it towards a wall etc.)
by the way, my phone was not rooted. no time to root these days. and of course the phone was not starting.
what is your idea? what happened phone? what should i do?
if you reply, i will be appreciated.
A big advice for people reading this, dont remove the battery when your phone is booting.

I hope someone has a solution, since I have the same probelm...
I searched everything and tried every tool in this forum, but no success...

dude, unfortunately those solutions not working on my device.
when i connect charger and i replace the battery, within seconds phone boots itself without power button. it should be this way. removing and replacing the battery helped me to start to boot.
i sense this case a bit different from that solutions.
i need to try with a different battery. my wife has nexus s also. she is very lucky she has no problems i have experienced so far. i will try with her battery.
i think there is a matter with mainboard.
by the way i forgot to say that i dropped my phone last evening. just after then phone was acting that i'm pressing long onto power button. and power button finally stopped working when i remove the battery.
i think this is happened because of dropping the phone from my belly high.
but the last thing i have done which removing the battery while the phone is booting, i wish, i should not have done. i could use it without the power button.

If you have not rooted your device, you should have you warranty, right? Take the phone back to the carrier, and tell them about your problem. o.o Sorry, I'm of no help, but you're in a horrible situation. Wanted to at least give a little help.

Same exact problem here.
2nd of August - mom's phone turned of and just would not boot or prompt at all. The modem heats up when power is turned on or connected.
Tried
The unbrickable methods (but the computer would not detect the device in any form)
A JTAG - I was able to write the recovery and bootloader - assembled the phone and it just won't boot or prompt
Need to try
Another battery to see if it solves the issue.
Removing the xOM5 resistor and converting to a development S5PC110

Tried another battery - no luck
Did the resistor removal and converted to a dev board - Unbrickable now detects the board!
trying to get the device into fastboot - will update

I had the same problem few months ago. Power button had died. While I was able to boot with remove battery and connect to charger option and I was rooted. But after a week I decided to take the phone to Samsung service center to get the power button replaced. My phone did not have warranty. Samsung took few hours to get the power button replaced and it costed me about $7. I think that's the easiest method. They did not have a stock of I9020 power button, so they fixed a I9023 power button.

Any update? I'm curious to see if you get it working. Had the same happen to my NS a few days ago and would like to see if I can get it going again so I can give it to my stepson.

I've given nexus s to samsung service. Actually, power button may be handled by replacing with new one, but with no hope, it will not come back when i read messages about mainboard failure. I will update news whenever it's possible.
we'll see.
I would like to hope it is kind of software matter.
Pls god give my nexus s back, i got extended 3500mah battery.
grrr....

So with the hardware mod - instead of selecting Nexus S -> I tied the Galaxy S in unbrickable - first time I've seen the screen alive! - puts the phone into download mode and I can disconnect from the usb and it stays in download mode! .. when i tried to flash odin I get a "There is no PIT partition" error -> this ofcourse is with re-partition and bootloader update UNCHECKED
When I tried Heimdall it wouldnt let me flash without a pit file. So trying Heimdall 1.1.1 - I get Failed to Access device Error: -3
Any chance some one with an i9020T can do me a huge favor? Use Heimdall 1.3.2 - download your PIT file and upload it here?
reaching for string ends out here :/

The power button had to be replaced. I shorted the connection when ever I had to press the power button during the boot sequence. That's how I fixed mine.

[Q] Nexus 5 constantly rebooting at 'Google'

Guys my gf's Nexus 5 shutdown today and just refuses to boot up. It doesn't do anything with any of the keys pressed in any of the combinations that are defined. But once it is plugged in to the charger or USB, the google logo pops up and the phone keeps on rebooting to that logo. If the volume down key is pressed when this is happening, the fastboot mode is visible for a second and the phone keeps rebooting. No action can be done in the fastboot mode due to the quick reboot. I am attaching the video of the problem. Any help guys?

If on battery, then the phone does nothing. If plugged in to charger and the key combination is tried then the phone keeps on doing as shown in the video.

Don't know what's going on.
Try doing that but with the phone connected to a PC that has adb and fastboot installed.

You have a fauilty or a stucked power key.
If it is just stucked then you can unstuck it by abusing the power key or taking the phone apart.
If it is fauilty then you have to claim your warranty.
If you disassemble the phone you will void your warranty

A few days back, she had got the power button fixed because the power button response had become intermittent and the phone was rebooting randomly. She had taken the phone to a LG service center first, but they told her that changing the button or trying to fix it might damage the board and told her to change the board altogether. So we took it to a local repair guy who fixed it and the phone was working fine till yesterday when it shutdown all of a sudden and then the rest is history.
Note: The phone is not under warranty as the phone was bought from Dubai and we stay in India. No international warranty.

Then you have to visit that local repairer guy pay him to replace the power key again or pay LG to replace the mother board.

Yeah the repair guy you dealt with must have fixed the button short-term but in doing so inadvertently caused it to short out. Meaning it needs to go back to a repair shop (better one) and cross your fingers that it didn't short out more important components

Okie. Will take the phone to LG tomorrow or over the weekend.
Guys please clear my one doubt. If it's the stuck power button, what does it have to do with the phone not doing anything when on battery but decides to go till 'Google' when plugged in?

Had my Nexus 5 for about a few month now, and have loved it till this morning, it decided to just shut off (full battery too) and i tried to turn it on and it is now just constantly starting up to the "Google" splash screen then shutting off.
Sometimes it gets to the the 4 color circles then shuts off.
I want to enter into recovery mode, but I have no time to click recovery mode as it reboots frequently
One thing i noticed when it did boot up was the power button seems to be extremely sensitive and volatile

I had this same problem.. It constantly rebooted and wouldn't let me get into recovery.. Every time I plugged in the charger it would reboot also. You have to let the battery completely drain.. I gave it a couple weeks.. then tried it again and it worked.

Found a solution
Well same thing started to happening with me yesterday after installing android L's developers' preview in my nexus 5. It worked well for first 4-5 hours but then after terminating a phone call when I put it back to my pocket problem started. I searched many forums for solution then I decided to re-install from image. I connected my phone to My PC (Which had driver installed & fastBoot setup) dramatically my phone started working well. And I detached my phone from PC. So I thought it might solved because after supplying charging. But after 3-4 hours it started again so I directly plugged in to electric socket but it kept on rebooting. Then I turned on my PC and attached my nexus 5 with it. Again it started dramatically.
Still I don't know the exact reason behind it. But good new is my phone is still working since last 16 hours... But I took care of not to launch some apps listed risky for developer's preview. So I thing some incompatible app launch may be a reason... but still its only "may be"

If it happens again try what I just answered and let us know if it worked for you? So we can come to know if solution was nexus 5 specific or android L specific. Also mention the OS version, please.

If it happens again try what I just answered and let us know if it worked for you? So we can come to know if solution was nexus 5 specific or android L specific. Also mention the OS version, please.

Nexus 5 DEAD - QHSUS_BULK

Hello everyone,
This morning while I was having coffee, my phone started playing jokes on me. At first it got really slow while doing the easiest things, like checking a mail, send a text and make a phone call. 10-15 After that I get a notification, Phone was locked, I tried to unlock it. I did spam the button like 5-10 times, Screen won't come up, but notification LED was working. At that point I thought that the power button was pretty much done for. Nope not the case. I held it down for 10 seconds, phone actually powered down. No chance in hell I could turn it back on. At that point I just went home. Got home plugged the phone into my PC. As soon as I did that, Windows started to check for a driver, had to wait almost 5 minutes to find QHSUSB_BULK.
Now, doing a bit of a search I found out that this could be the result of different problems, One that has to do with the memory just dying cause yeah, Nexus 5 and the eternal memory problem +Lollipop screw around with Data partitions, another that has to do with Roms, another that had to do with custom recovery.
What the hell is in my case? I run a custom Rom and a custom recovery, Atm I have Cyanogenmod 12.1 and lateste TWRP recovery.
I have a handful of tools at my disposal, a Cable, a good keyboard and a iron will.
In this case, Can I do something to fix my phone from home? Can't really send into warranty as I have custom software that's running on it and I'll just get a generic response that basically tells me that my warranty was voided due to custom software running on the terminal. We all love generic response like that, Don't we?
TLR: Phone died this morning, I couldn't unlock the screen and I thought it was the power button be cause, the notification led was still working. At that point I just powered it down by holding the power button down for 10 sec.
I wasn't able since to power it back on. If I connect it to my PC I get QHSUSB_BULK.
Hopefully there's some one who can point me in a direction ASAP. I have no backup phone atm and I really need this one to actually be ALIVE again.
Can't send it to Warranty because I run custom software on it. GSM Services/Fix Shops are out of the question too.
Pls halp ASAP
Will pay in Galactic Credits.
Thanks!

Your best bet is to try this, http://forum.xda-developers.com/showthread.php?p=51823398. Good luck, your device is not in a good state.

I have the exact same problem but this answer doesn't help. This solution requires that you can turn your phone on in the first place. He specifically said he can't turn the phone on at all. Same with me, no matter what I've got nothing. Need help!

Thanks to everyone.
I used the board diag - clicked Start and... it said "failed to open partition from EMMC". The test aborted. I think my phone is gone for good.
Oh and I had to take the battery out, plug it in, and sometimes re-attached to latch that goes over the battery several times before I could even get it to read anything in Device Manager. Before that it would say "failed USB connection".
This all started yesterday when the phone just spontaneously put itself into a boot loop while on charge. I tried to do a factory reset but it froze. After several hours I tried to cancel it. The Nexus went full brick.
Thanks again

Nexus 5 new screen is not working anymore

Hello,
I had an accident and after that my Nexus 5 screen was broken. So I decided to buy an new one from Amazon (~60$) and I tried to replace the screen on my own.
Yesterday I replaced the screen with a YT-Video, then I charged my Nexus 5 an the "Charging-Symbol" showed up.
After that I left the house for 2 hours and when I came back (I left the Nexus at home for charging ofc.) I tried to turn on the phone and nothing happened.
Then I tried to press power and volume down to get into the boot-menu and this also worked and the screen showed everything perfectly (!) and then I tried to start my handy from the boot-menu.
Until then everything has worked well but during the start progress I noticed that the (starting-)animation is really slow and laggy, so I decided to try to reboot my phone by holding power off for around 10 secs.
I tried to start my phone one or two times more and tried to get into the boot-menu, restart bootloader, etc. and then I realized that my phone didn't even want to work anymore. I could(and can) neither get into the bootmenu nor simply start it...
Do you have any ideas?
What suprised me the most is that it stopped working so quickly, so I concluded that I replaced the screen right but anything else went wrong...
Please help me :/
PS:
USB-Debugging is turned off and I cant access my phone with my pc or anythin else

Leave the phone on the charger for about an hour and then try to get into the bootloader.
When my phone is in the process of booting and I force it to power off by holding down the power button, it will not power up until I either leave it on a charger for a bit or leave it power off for a bit, usually 5 to 20 minutes.

Thanks, now I could get into my phone and enable USB-Debugging with much lock D)
My problem is, that my phone runs very unstable and shuts down often so I can't really work with it.
Do you know any solution and the more important question:
How can I save my data? I think, that I can save it anyhow if I enabled USB-Debugging with the bootloader and a pc, can't I?

Yes, you could pull the data from the phone using ADB commands.
You could also flash twrp to the phone. Once flashed, you could boot into twrp, mount the data partition, and copy data from the phone to the computer.
You could also use twrp to create a nandroid backup for safekeeping.
Is it possible that there is a loose connection in the phone? Have you tried disassembling and re-assembling?

I have now moved on!
My charger cabel was broken but now I got a new one!
I can start my Nexus (with some issues) and it runs but sometims it still shuts down and always when I try to plug in my cabel into the Nexus the screen gets black (but on the side you can see that the screen is light up in some way, idk...)
Is there a reason for the heating and for the shut downs? :/

I'm not sure but it seems like the screen has suffered a hardware malfunction because you can see that the backlight is on but no image.

And that means what?
And can I do anything for it? Maybe flash it or something?
Reset, etc..

With a hardware failure, there's nothing that software can fix. Did you try disassembling and re-assembling the phone?
With the old screen, can you see anything on screen? Did the phone power up and charge properly? If yes, put on the old screen to test the other components to see if it charges and powers up.

Yeah first sentence makes sence..
I swapped software and hardware, sry
my other screen doesn't work at all, completly destroyed...
The problem is that I can't imagine what should be the failure...
And yeah, I already tried disassembling and re-assembling it...
Still same problem

I have used cheap 3rd party screens to replace a few N5 phones and they quality is very inconsistent so I wouldn't be surprised if a 3rd party screen fails after a short period of use.

Nahh but the screen works I think..
Everything looks clear etc and the screen wasn't really cheap with 65$-70$ I guess..
I think it's something else because my phone gets really on near the CPU and this can't be because of the screen...

Where did you get the screen?
If it gets really hot near the cpu, then something else is going on. Could it be possible that there is a short-circuit somewhere?
Since the value Canadian dollar has dropped, I'm also paying about $60 for what was a $40 screen.

Yeah, I also thought about a short-circuit but I don't know how I can test this.
When I try to start my phone it fails like 4-5 times and then it works most of the time. The fail looks the following:
The "Google" logo appears and then suddenly the screen gets black, but not the "out"-Black (so that screen it out), I mean the "on, but black"-Black (hope u can understand.. xD)
During this 4-5 Tries my phone feels like 40°C-50°C (sry im from Germany, idk the conversion to °F value.. )
After this (I got the phone running one time for about 20 minutes) the phone doesn't heat up so much, if it starts right I think that the temparatur problem is over, but there is still the problem (also if the phone is running for 20 minutes) that it suddenly shuts down... :/
Sorry, idk much about canadian dollar, like I said im from germany and I payed around 65€
Google says, that this is around 67 (US-Dollar)

I don't know what to suggest other than either getting a new battery or new screen. Both items can be very expensive.
