One X will not turn on

Hi there,
I have a 6 day old One X, Telecom NZ phone.
Last night while using maps the phone locked up, I allowed 30 seconds for it to come right and it didn't so I held down power for 10 seconds to reboot. Upon reboot I was presented with the HTC Quietly Brilliant screen with the message below in red "This build is for development purposes only. Do not distribute outside of HTC without HTC's written permission. Failure to comply may lead to legal action." The aforementioned boot screen would remain indefinitely until I pressed the power button upon which it would momentarily turn off before rebooting to the same boot screen.
I feel at this point I should note that the phone is completely stock and I have not begun to tweak anything at all yet.
So after this screen being on for an hour or so, possibly enough to drain the battery (battery was near 40% before the phone began acting up), I long pressed the power button and it turned off, that was the last time I saw my screen display anything. Assuming the battery may have died coincidentally at the same time I pressed the button I was hoping a stint on the charger at home may fix everything. Charged for a couple hours on my PC with no sign of life from the phone, then a couple hours on my wall charger with nothing, then all night approx 10 hours on my PC again and still nothing.
I have also tried all the button combinations including those recommended by HTC for hard reboot and hard reset.
These include: Hold vol down + briefly push power; 30 seconds hold power; hold power with both and either of the vol up or down (tried all combinations).
By the look of it I am in for a warranty claim, do you think so?
If so shall I talk to the chain store I bought the phone from or to HTC directly?
Thanks for reading
Van

I don't know NZ consumer law, but try to get a replacement from the store.

I believe I have the right to a repair, replacement or refund, which option is of their choosing, usually the repair option, and from past experiences that can take multiple weeks I'm also reasonably confident a courtesy or loan phone wont be on offer either.

Even if it's a week old?

Yeah I'm pretty sure it doesnt matter if its not working out of the box, they have the option to send for repair
I will go in and talk to them this afternoon

Is it just a dodgy Power-On button...
I Think with a lot of HTC handsets there is a replacement power button, I think it's VOL+ on most handsets...

Hi thanks for your suggestion but I have tried all buttons and all combinations repeatedly before taking it back.
I have now taken it back and due to lack of HTC One X stock and decreased price on the Galaxy S3 I was able to exchange the phones directly, really happy they agreed to direct replacement rather than repair as select chain sotres have done to me before even when only 2 days after purchase.
I do not know how to but this thread should now be closed despite not being solved
Thanks

Hey,
I had the same problem, send it in for warranty and got it back If i want to replace mainboard for 223,36 euro.
Broke as I am I went searching and found a thread. I will search the thread for you and link it. It is a script you run with your phone connected to your pc/notebook. That's how I charged my one x. Unlocked it with htcdev.com flashed cwm and installed custom Rom. Or run RUU.
http://forum.xda-developers.com/showthread.php?t=1658084
At first it didn't load to 3860Mv (above 30%) this was due my pc after it tried the script on my girlfriends laptop it charged!
You can also try to send it in to HTC and cross your fingers. =)
All credits to the OP of the thread.

[Q] Please help - real noob!

So my One X got stolen for the second time now (yeah, lucky me) and this time I wanted to buy it used. Well I got one very cheap, but it seems to have a software defect of some sort.
I charged it briefly and it actually seemed to work. The red light was on and so I left it for another two hours to charge some more. Unfortunately this did not help (would have been too easy). The guy I bought it from showed me, that when he plugged it after a minute or so, the led would blink red for a few times. This does not happen every time however. I tried the hard reset with no response. I tried to restart it by holding down the top button with no response. Only once it was vibrating like when it is booting, but the screen stayed black and the button row was blinking shortly.
When I connected it to the PC it was able to install the HTC Android Phone USB Device but showed that there was no driver found for APX. I have never seen that one before.
I've tried to find some answers on this board, but I don't understand jack I don't want to learn all there is about smartphones, I don't root them, I don't install anything that doesn't come from the market. Usually. As I said, I am a total noob, so please use noob-language
PS: The seller couldn't tell me anything about the mobile. He said he would sell it for a friend. I fear it's stolen, but that's tomorrows problem since I can't see the IMEI w/o getting the phone to work

The original sim tray has the IMEI on it.
Are you saying that the device is reported as APX in device manager? Then it's back to the retailer or HTC, it's not recoverable.

Thanks a lot for the tip with the IMEI. I went to the police station today and checked it out, luckily it's not stolen
About the software: The PC does recognize the phone as HTC Android Phone USB device, however it also finds another new hardware called APX for which it can't find any software. So does that really mean it can't be fixed at home?
And if that's so would I have to pay if I send it in (I do not have a receipt) or does HTC know whether I have warranty (which should be obvious since this mobile is new on the market).

- Turn off your phone by holding the power button.
- Hold the Volume-Down button and turn on your phone (while keeping the Vol-Down pressed).
- Do you get to hboot?

No, I've tried that before, it didn't work. I did send it in yesterday. They said I should get it back in 10 days time. I hope this is covered and I don't have to pay for it.
Thanks for you help!

Good luck mate! Hopefully you won't have to pay anything

So I did get it back, but it won't recognize my SIM card. HTC told me to send it in again and I am really pissed. I don't want that. It seems to work just fine, it just won't accept the SIM. It asks for the PIN code but then it says my SIM is not right for this network (which is any network I am trying). Any solution for this?

Phone sounds goosed. Get your money back

Any news?

[HowTo] Getting out of APX Mode

Hey guys,
Please stop PM'ing me about APX Mode. I get like 10 PM's a day.
How to get in
Nobody really knows. The most common way has been pressing volume up and down together while device is off and then plugin USB while connected to a computer.
How to get out
When your device is in APX Mode, HTC fixes it in repair. Someone here on XDA PM'd me with this video and said it should work: http://www.youtube.com/watch?v=rsnl_LIgzt0
I have not tried it myself, so just give it a try and share with the rest.
All the other discussions about APX can be done here, please stop pm'ing me.
Thank you!

Pressing vol up and down while phone is off works only on some devices. Some pm'd me about getting into apx mode with this. PC will recognize the device as "APX something something"

I too have joined the APX club.
I bought the phone off eBay, with a damaged screen not displaying anything.
When plugged into USB, it would charge, and the PC recognized it as a HTC One X.
When playing with the buttons, I could hear the startup tone.
Since fitting the new screen- very carefully - the phone has gone into the APX mode.
The charge light has come on once whilst plugged into the computer, after which I swapped it over to the mains charger. The red charging light stayed lit for 10 minutes, then went out.
Since then, I've seen no life whatsoever other than the APX mode.
I have tried the YouTube video above, and many combinations. I have tried charging up the battery directly via a hacked USB cable. I have tried powering on the phone with what I think has been every possible combination. I have tried leaving it plugged in overnight. I have tried plugging in the mains/USB charger while pressing buttons. Something isn't right.
The battery can light up a 3V LED, and today I have just found up a multimeter, so I will check the voltage of the battery as I believe it needs at least 3.6 or 7 volts to start up.
Yesterday I tried speaking to Vodafone, who didn't have any software to flash the HTC other than the publicly available software from the HTC site. I also spoke to Carphone Warehouse, who also didn't have any equipment. Neither assistants or the engineers in the shops had come across the APX mode before.
I'll update this thread with any more of my findings, as it is one of the top results in google and I suggest others do the same. Hopefully together we can work a way out of this without the need to send to HTC.

Try holding the power button for roughly 40 seconds with charger disconnected. It might work.

You could also try "nvflash" reboot commands. Since there's no nvflash package/drivers for the HOX I'd try with the Asus TF packages. Though, I'm pretty sure someone has already tried it without success
Also, are you able to connect the device in adb mode? Adb without being in OS works if you power off, wait couple of seconds an connect it to the PC without powering on. You should see the red led constantly on. If it works try "abd reboot oem-34". I'd appreciate it if you could report if it did work.

Afraid I've tried all that. ADB isn't available, only appears in APX mode.
Phone does nothing.
Only interaction I can have with the phone is to connect via usb, and holding the power button for 10 seconds changes it to APX mode. Otherwise it's an unknown device, for which no drivers are available- I can force drivers onto it, but its hard to tell exactly what it's looking for.
I have also tried the NVflash utility for tegra 3 devices- I have a transformer prime, this is what made me purchase a tegra 3 based phone.
Anyway, the NVflash utility cannot operate with the phone, it merely displays as an unknown device.
No red LEDs, no nothing.
Cronus, trust me, I've tried
Still, I've just popped the battery out and checked the voltage- 2.64V - WAY below where it needs to be- around 3.7 volts to boot up.
I've popped the terminals out of the battery connector, and connected them to the hacked USB on the positive and negative. It's currently plugged in to the HTC wallcharger, and it is charging the battery up.
I'm going to leave it on for an hour, then I'll stick it back in the phone. More updates to come :good:

Just send it to htc or your carrier mate. This happened to me b4 xmas and I sent it back to my carrier. They charged me 76 pounds and gave me a brand new phone even tho they said they had to change a circuit board. Sorry to say this but if everyone that gets their phone into apx mode should sent it to htc so they realise that this is a design fault and not just caused by unlocking the bootloader. Maybe some haven't unlocked and are also experiencing apx mode?

I bought it off eBay, the warranty is void. As far as I know the bootloader hasn't been unlocked, as the previous owner said they'd only had it 5 days before they dropped it on the floor and the screen popped out. But I have had it working properly- I could hear the startup sound being played when I had it.
I've spent £58 on a new screen, to spend another £76 just isn't economical.
The battery is now back in the phone after being charged to 3.8 volts, it still doesn't appear to be doing anything- I'll post back if there are any further developments.

I have found a company which say they have encountered and fixed the APX mode on the HTC One X before - www.uk-repair.com
Quoted me £44 to get it fixed. I've politely requested any information they feel comfortable contributing about the APX mode be posted on the forum.
Fingers crossed

I made an insurance claim for my APX'd phone as it was only £25 excess; it was sent to thefoneclinic.com who have deemed it beyond economical repair so i'm getting a replacement. I'm guessing either something on the motherboard was actually fried or only HTC themselves can recover from APX mode

AW: [HowTo] Getting out of APX Mode
To the people stuck in APX mode; try constantly rebooting. Like powering on hundreds of times. TripNnRaver got his device out of APX this way, but obviously he is stuck in APX again after a reboot. At least he managed to boot into the OS for a short time.

This happened to my phone. Installed Trip's endeavor unleashed v003 and it bricked my htc one x. I kept on rebooting it and managed to get back once to the OS but when I restarted the device again it never go back now its bricked!
I don't know though if my ONE X is on APX mode. I can still go to fastboot and recovery but everytime i copy files thru ADB, from my pc command line it says success but when i try to flash it from clockwork the file i copied isnt there. I tried flashing a different recovery but it seems that the device is readonly and i couldnt delete or write to it.

APX is not a battery or a software issue, it's a hardware issue !

M8 Bricked, i need help please.

my m8 is bricked, is not in recovery mode, does not enter fastboot, not turn on, only red light blinks when plugging the charger a few times, but the pc recognize me how Qualcomm HS-USB QDLoader 9008.
someone I can spend some method to restore the system?

Those symptoms typically mean the phone is bricked. Qualcomm download mode is a bad thing, not a good thing. Were you doing anything to possibly cause this condition, or did it occur spontaneously?

Its possible the update was overwriting something critical like hboot, and some error occurred. Doesn't sound good, between the symptoms described, and the fact an update was being applied.
Try charging for several hours (overnight) on the wall charger (not connected to PC) then try the different button combos (holding each combo for a minute or more): power+vol up, power + vol down, power + vol down and vol up, power by itself.
Try the button combos with and without the charger connected to the phone. If none of that works, I'm inclined to believe the phone is toast. If the phone is stock, applying stock update, and less than a year old, you might have some recourse by warranty (although folks having any kind of warranty is becoming less and less likely as this phone ages).
Otherwise you may try to find a local repair shop that can JTAG the phone.

That's true. Other possible options would a (reputable) repair shop that can replace the motherboard. Or you may see if HTC will do that (for a fee). But as its a US version, I'm not sure HTC will provide that service.

Question The device doesn't start

Hey guys... I'm having a problem with my brand new Pad 5. As soon as I received it and opened the box, I tried to turn it on, but it just flashes the first bootscreen (with "Mi" and "Android" signs) for 1 second or less and then shuts down.
I already tried to long press the power button, press the vol- and power button at the same time, vol+ and power button... And the result was the same with the boot screen flashing and nothing more.
Anyone else had the same problem? If yes, how can I solve this?

Did you charge it first?!

I don't know how to do it (the firmware)... The device doesn't enter fastboot or respond to any command I knew... Return it maybe is the only option for me, but it will be a pain in the @$$, cause I bought it on Aliexpress and had to wait 30 days to receive it... The forum is (was?) my chance to avoid this headache

No sense buying broke phone... life has much worse surprises than this.
This just an inconvenience.

Take pictures before packing, double box it and insure it. Call the credit card company and explain what happened. Hopefully the seller won't cause any problems but... cover your ass-ets.
