[Q] Dead phone after update, any way to bring it back

Hi guys, need very quick help from you, as I think I have bricked the phone which suppose to be a Christmas gift for may son. I was trying to revert phone from root and custom rom to stock. I've downloaded older OTA update (one of very first ones with android 2.2) an installed it in bootloader. Phone booted fine, and I went for official update. It showed to me there is update available to android 2.3. I have downloaded it and phone rebooted in to update mode. After progress bar gone to the end it disappeared and phone stayed in that update mode (logo with phone and green arrows shaped it to circle) for nearly half an hour. I though, some thing had to vent wrong so I decided to turn off phone, but power button gave no effect, so I pulled battery out for few seconds. After I have putted it back phone never turned on again. I mean is completely not responding. Pressing power button for even minute doesn't wake it up, it is not possible to go to the bootloader. There is no characteristic vibration when it turns on. Basically it behaves like there is no battery in socket but there is, and it is fully loaded as I charged it before updating. When phone plugged to AC or computer LED is not lighting as well whatsoever.
Please, can any one help with this one? I in rush as phone is a Christmas present for my son who lives in Italy and I supposed to ship this today to make it arrive b4 Christmas. This is why I can not spend to much time on searching forums.
Thank you

Check battery pins

After reading what you said i think that you placed battery wrong. Check the pins inside the phone with battery pins.

That was my first idea too but, no m8, battery is placed ok....

Try pressing volume down+power button for a while then leave the power button while still pressing the voulme key. You should boot into the bootloader.

Tried that too, still dead

Try connecting you DHD to the PC.
Download one of these Stock RUU's : http://shipped-roms.com/index.php?category=android&model=Ace
Run the installer from PC. See if it detects the device.

I understand I should not be worried that all of these RUU's are listed as for model: ACE?

Not at all. 'Ace' is the codename HTC gave to Desire HD/Inspire. Just choose the RUU that fits your location(i.e. WWE stands for WorldWide Edition).

OMG! I was previously looking for stock roms and everytime I ended up on that site from your link I was annoyed that someone is giving a wrong link to roms for wrong phone. Silly me!
I am downloading right now.

My idea is to double check again the battery position in the socket and if it is ok try to leave it 5 minutes alone on the AC adapter. If this will not give good results, go to the appropriate HTC representative.

when you connected it to your computer... did it ask you to install qload drivers?
if not, go into device manager on your computer, then plug in your phone. If you see an unknown device that shows as qload something or other, then sorry to say, its bricked.
The only way to recover it now is via jtagging or replacing the mainboard (which generally is what they do when you send it in for warranty repair)

Yes, I thought about it as phone behave like it has no power at all. But this is not the case, as I have been flipping that and another battery in every possible position. And I know which one is correct as I can see where pins are in battery pocket. I left it alone under charging and other time with no battery at all hoping that will hard reset phone. No effect at all .

I had drivers previously installed. But I am not entirely sure are we talking about same thing as I don't know what QLOAD is. Anyway comp doesn't see any recognised or unrecognised device that could be my phone...
I am not worrying about damn phone as if it is hard bricked tech guys in service will not probably spot that it was rooted. So they will replace, or if not I will go to insurance company. Problem is it takes to much time, I wont make it b4 Christmas.
Thank you guys,
anyone has some other ideas? Please...

desperation bump

Sorry.. It really seems to be beyond software-repair, If it cannot boot in the bootloader or be recognized by PC there's really not much we can do. We need the device to start in some way.
Although one last thing that we haven't tried and can try is to see if it can be accessed via adb or fastboot. (Although I highly doubt it since the RUU also wasn't working).
I've attached the adb and fastboot files required to test that. Extract it, double-click on StartHere.bat and type "fastboot reboot" or "adb reboot". If it returns an error citing device not found then this too has failed.
(This probably wont work.. desperate action)
Another silly thing that might be tried is to try to put your phone on charging via a charger(not USB via PC) and then try to switch it on. Try normal switching, switching on to bootloader(volume down press)...
If these don't work then you really should give it to the repair center.. you're right that they wont probably realise that it was rooted and would probably change the main board.

Sigh... I got "waiting for device" forever in CMD... As you said, it's dead. Gonna send it to HTC in Monday...
Thank you all, appreciate your time

Hello hedeon,
I have the same experience today, as you state in the first post in this thread.
Did you, and how solve the problem?
Is there people with the same problem? This morning I receive notification about system update for my HTC Desire HD. The rest is exactly same problem from the top of this story = death + death + death.....

The problem is that you PULLED THE BATTERY WHILE UPDATING! Have some paitience. I switched on my DHD after 3 months and it needed updating. Takes around 20 mins to complete update

May be, but updating started with downloading, then resetting, and then green line was growing up to 1/3 of total size, and at that size stay more then 20 min. Then I try to to push every button, and every combination of buttons, and after 10 minutes more I had pull battery out.
Was it too impatient ?

What was the Android version before you rooted if you can remember and which tool did you use to root?
From what you wrote earlier, it asked you for a 2.3 update which means you probably flashed a Froyo RUU as stock, to bring the phone back to stock ofc.
However, if your DHD came with stock Gingerbread, flashing a Froyo RUU will most definitely screw the phone. I'm not sure if it's beyond repair atm or not, but if that was the case, even if you didn't mess with the battery, chances are the phone would never boot anyway.
Look into AAHK thread, I think there is a good how to there.

One X dead APX in device manager

I was just browsing my phone when something came up on the phone about an update, it wasn't the rom or htc update, then as I thought about what to do the screen went blank back light still on, I let it for a minute or so in the hope it would resolve itself but nothing, so I held the power button to reset the phone turned off and since then I have been unable to turn it on again, in the device manager when I connect the phone it says APX some times dropbox will show and ask if I want to scan for photo's
Help the phone is rooted and I'm worried about the warranty!!!
Thanks In advance

Stop worrying about the warranty. As far as a problem like this goes, you don't have one.
You say you held down power to reboot and now you can't turn on but you go on to say drop box sometimes works? Can you elaborate?

It came on once and said there were no photos to update, it hasn't come up since, all I get is APX, if I hold power it goes off for second then APX comes up in device manager, I've also installed the apx drivers and I can use nvflash but I wouldn't know the first thing about what to do here, nv flash does work though.

Could you explain to everybody here what you did exactly ? Might be interesting for a few people here !
1 : Did it happen just by waiting for some time ?
2 : Did it happen by rebooting the phone ?
3 : It went into recovery when i .......

through APX mode we can flash bootloader i think, so if we'll know how to use it properly (how to enter in it, work with it, and exit from it), we won't need s-off!
so if somebody came out from apx, it's a good starting

By rest do you mean with it charging or not? As I am now having this problem and need a way out!

I think its very difficult to flash stuff with nvflash on a protected apx mode.

I got out of this for leaving the phone on charge for a short while, then whilst still on charge powering on and it came back to life!

Has anyone else experienced dead one x in APX Mode

Hi all, I've began to realise that no one can help get me out of APX mode on my one x but after reading stories about the Asus Transformer battery reset and LG optimus reboot from apx I am convinced there must be a way to get the device to reboot into bootloader or perhaps flash a boot.img to reboot the phone.
I am just wondering if anyone else has experienced apx and what they did about it......?
And if anyone can explain what may have happened to cause the phone to simply go dead and stay stuck in APX mode. A bad boot.img, overheating(although it didn't seem to be hot)ect....?
If I was to have the phone repaired where would I be able to do that in the uk apart from the network and HTC?
Does anyone think that removing and replacing the battery will allow the phone to boot normally?

My phone is also in APX mode after a strange crash during flashing a ROM and a strange kernel flash...

what is apx mod?

Muy phone does not boot at all, when I plug into the pc it says apx in device manager, what ever I try it will not boot

a friend of mine had the same after playing for an hour or so.
The Device won't boot up at all and only showed apx in device manager.
Send it to htc or wait till there's a solution for that.

APX mode == NVFlash recovery mode. A low-level recovery mode that allows you to flash the whole device. There's no known way of getting to this mode, but several people are reporting it and suggesting a faulty device is to blame.
You can try using NVFlash utility for Tegra 3 to find out more. Fetch partition table, download partition data, flash new data etc. Search forums for more info on nvflash.
But, chances are that your phone is just busted.

HOX in APX mode
I have HOX indicating APX in device manager. Just tu add one more sad story with short description of attempts to solve it.
I have two HOX one is ok. Both handesets diassembled fixed WIFI issue changed battery from good one to bad with no results, when replaced motherboard everything works well but that is half of the phone. APX is still appearing in device manager when only motherboard connected.
Tried all other methods nvflash, drivers etc as others with no results. Hope something will leak soon.

I also bought two, one for my son. His has the same problem. It won't boot but shows in devices as apx device on the pc.
Took it to my supplier four weeks ago and after many emails they tell me it is fixed but they wont send it for another week.
It took ages to get it delivered the first time. Last time I buy gadgets online. Any other Aussies get one from Topbuy or Kogan and had trouble with warranty?

Sadly mine got stuck in apx mode and I returned it to my carrier 3UK. They said it was due to me loading illegal software on it and demanded I pay them £76 to repair it. So I want my phone back now and agreed to pay it on my next bill, I will dispute it when I get it back. Looks more and more like hardware to me.

APX Mode is supposed to allow access to an nVidia based device if it is soft-bricked, but unlike other nVidia based devices such as the ASUS Transformer TF 101/201 or LG Optimus 2X, it is impossible to revive an HTC One X that is stuck in APX Mode. No-one has a guaranteed way of getting into APX mode, let alone getting out of it. As you may or may not know, the One X is very locked down and restricted. The bootloader is locked, and it's very hard to get updated stock ROMs as RUUs. Surprisingly, it is easier to get a custom ROM working through fastboot/recovery than it is to get a stock ROM working due to all the restrictions.
In fact, the One X is so locked down that even NVFlash cannot access it in APX Mode.
For example, if you try to send any commands to a One X using NVFlash, all you'll get in return is this error due to its heavy restriction:
Code:
Command send failed (usb write failed)
I have wasted 5 hours trying to revive a One X stuck in APX Mode, only to discover that it is impossible. Even HTC themselves can't fix a One X stuck in APX Mode - that is why they accuse you of installing illegal software, but in truth they have to replace the motherboard because they locked themselves out of their own hardware. This is a result of flawed internal hardware design.
So in short, don't think just because a computer can dectect the One X means that you can still save it. There is a barrier in the device itself that is above software-level.

Ah yes, this "news" is not new ...... its a known problem for several months already.
But thank you for sharing
A search would have come up with several threads, this is one of them

i am trying to fix a one x stucked at apx mode :/...are there any news about this issue?? probably a fix?

my phone doesn't charge/boot... probably dead

i already searched a lot, but i didn't find anything useful so i post here hoping that someone can help me. i really need my phone so before send it to htc service i have to try to get it back working.
simply yesterday my phone went off because of low battery. when i got back home i try to charge it, but nothing happened. so i tried using pc in order to see if something happen, and led started to blink slow (orange led). so i turned it on, and it worked. then i was using it (connected to the wall charger) and it frozed, at 9% battery. so i tried to restart it (by pressing power and vol down), but nothing happened... it was completely dead, i tried:
-wall-charger;
-pc-usb;
-change different charger/different usb cables);
-i left it the night connected to the charger);
-no adb, and obviously i can't get the phone in recovery/bootloader/fastboot...
i was on hboot 1.3x... don't remember which number cause i updated the hboot a few days ago. i was on viper rom and i was using the tripndroid kernel based on official nvidia sources (really like their works )
hoping that someone can help me
however in the next days i will send it back to htc but i need to try something cause i really need my phone in those days and i have no replacement. will htc repair my phone for free? (remember that i unlocked it)

Crazy thing. U can't put the phone in bootloader mod?

That means your phone is broken. It needs a new motherboard.
Nobody has recovered from that. Some people have managed to get the phone working after APX, but it seems to go back to APX mode.
Sorry. Back to HTC it goes...

ok thanks... it is and hardware fault or it's because of the custom rom/kernel?

Hello ... Ive HOX With CID J_15 And Hboot 1.39

Get it repaired, you need a new mainboard

you can try to install the APX drivers made by Trip, maybe they'll fix this issue

You have to be very ....very lucky to get out of apx. And by most people the issue returned after a couple of hours....a day max !

yeah, pretty tricky too

Yes installing apx drivers doesn't fix anything by itself. It gives you the ability to communicate with the device in this mode.
But there is no discovered user way of entering this mode at present.
The only way that is known is an error before it gets to the bootloader. As the bootloader is the first thing to load software wise on the device during power on. The failure is happening before that which usually indicates that there is faulty hardware surfacing
