Dead phone in APX mode, now what ?

Hi,
I've got a HTC One x, which worked fine untill i flashed it with Cyanogenmod.
To start from the beginning.
I never liked the HTC Sense stuff to much, so i did with my HOX what ive done with all my other android phones. I unlocked it and installed Cyanogenmod. When i did that i started having stability problems, suddenly acore stoped, then gmail stoped and so on.
So i decided i wanted to try another rom, without much luck. After fidling around with it for a couple of days, it started behaving strangely.
Suddenly it could wouldnt turn on after beeing powered down, i had to leave it for days, then suddenly it would pop back on when left connected to a computer for a while.
I RUU'ed the phone, going back to HTC Sense, still giving me acore and other application errors. Then i installed a another ROM ( Jellybean ), and when i woke up one morning the phone was dead. It would not boot, not in normal mode, not into recovery, nothing. Ive tried all the tricks in the book, volum down + power, volume up&down + power, just power, just volum down and so on.
Ive been googling alot trying to figure out if the phone is beyond repair, or if there is any hope left. I noticed one day when fidling with it that when i connected to my windows 7 machine, the computer made a "USB CONNECTED sound". i looked in the device manager section, and there i see a unknown device called APX. I unplug the phone and it goes away, so i google and find that this is some low lever mode on the phone. My hopes are that this is a way of flashing some sanity back into the phone.
I found some APX drivers lying around on the net, and now it identitfies itself as "NVIDIA USB Boot-recovery driver for Mobile devices", not that this helps my in any way.
I read somewhere that you can use nvflash, but its not giving me much info.
Soooo....i have a phone which is pretty much dead, except for entering into APX mode ( the screen is black as if the phone is dead, no leds, no nothing ). Anyone have any smart ideas to how i can get the phone back to life ?

Nope. If you search this forum, the only APX advice I've seen is to drop the phone. Actually serious. (Don't do that)
Anyway, looks like you'll be returning it and hoping it gets fixed without them figuring out that you broke it.

hey do you already solve this problem ?? i solved mine by pressing volume + then plug the charger .. wait for sec. a red light will apear in your phone and it will charge.. charge it for atleast one night or for an hour. then try to boot in fastboot.. when you boot in fastboot flash RUU file or if you have a custom recovery try to flash a custom rom. ) press thanks if you helped you . )

contact xmoo he might be able to help, so far all i can tell you is that your phone is dead. htc should fix it if you act stupid and say it stopped working overnight.

[Q] Recovering an old Desire

Hi,
I had an old desire which I had given to my cousin. Sadly, one of his friends flashed something over it and since then, the device can't boot up.
prior to handing it over to my cousin, the desire was having an unlocked bootloader with CM 9 installed.
I've been trying to recover the device but with little luck.
After I pull out the battery and put it back in and plug in the charger, i can see the led which indicates that the device is charging glows orange. But the screen never starts.
Then, when I hold the volume down button and power button to get it into HBOOT, still nothing though it does vibrate.
Any idea how can I recover this device??
:-S

After the phone vibrates from trying to get in hboot, connect it to your PC. Does your PC find anything?

[q] htc one m8: Very very urgent assistance needed please!!!

Hi there
I've been writing about my problem for days now and I still haven't sorted it out. I'm just making the problem worse everytime I read all these forums. I messed up. I rooted when I shouldn't have. I get that. Please, I beg one of you to help me.
I tried to load software this morning and it just died. Screen went back. It seeemed to have been hard bricked. But then on the XDA forum I read how to keep playing with the up down volume buttons and the power buttons and it sometimes goes on.
Mine came on and it seems to have gone to recovery / install / etc screen (big buttons). Whatever I select, it always shows restarting and then the screen dies again and I have to play with it again. Obviously the software is messed up.
What software do I load here at this screen? What do I select? Recover or install or what? Please guys, the phone is on sufficiently enough that HTC will be able to see the phone was rooted. So I won't be able to get them to help. I need your help. Please???

Can't you go to bootloader > fastboot and use RUU?
i had almost same problem and managed to do this .
connect phone to charger or to pc via usb , keep pressing power and volume up bottons , unless phone starts charging (with charging battery logo),it will take 1 minute or so , after that remove cable and push Volume down and Power button together, keep pressing for a few second and phone should boot in bootloader , then you can choose fastboot mode and do RUU method , or if you have custom recovery , you can install some rom with it or restore backup (if you have one)

1. Put your device in bootloader/fastboot mode and run command fastboot getvar all and post result here (minus serial no. & imei no.)
2. Which recovery is that (you mentioned big button), TWRP ?

Hey guys
Thanks for the responses. It was just too daunting for me, so I took it to a repair centre. They will load the stock htc software on it.
Thanks anyway

OK ... no problem ...that's what we're going to suggest to you too. We have almost all the files needed on XDA

[Q] Htc one m8 black screen, won't boot up PLEASE HELP

So, I tried to restore a backup from TWRP. During the process, the system and cache were restored fine, but couldn't restore the data (for some reason, it said failed), so I figured it's alright, I'll just have to install all the apps again, no big deal. But, after I clicked the "reboot system", the screen went off and never turn back on.
I can't get in bootloader screen in any way, I haven't tried the Vol up + power button for 10s, and the vol down + power button, and the 3 button all together... Nothing works.
When I press the power button normally, nothing happens, not even the Htc logo screen.
When I plug it in, it only shows the battery charging icon. So I tried the buttons combination again (coz I thought at least the screen turns on now), but still, nothing happens, just the screen switch between black and the charging icon.
So, I left it charging overnight, and tried the buttons combination again, nothing works still.
Now I have no idea what to do, can anyone please help me?

It sounds like you hard bricked your phone. Try using this guide youtu . be/ rpA71FXddyU[/ but Im not sure it will work.
Only thing what you need is that computer recognize your phone, because when It doesnt then you should take your phone to local phone repair.

Hard bricked my M8 (help appreciated)

Hello,
Ill tell you a short story how I got this phone bricked.
So i got a OTA update to 6.0.1 (as I remember) and the phone started acting crazy. "system UI stopped working" message showed up once an hour and after that phone reboots. I got tired of my phone rebooting all the time so Ive decided to root it and install a custom ROM. Ive successfully rooted it, instelled TWRP and flashed a HTC M8 google play eddition rom on my phone. Everything was smooth except that it didnt recognize the SIM card and (again) it kept rebooting once an hour out of nowhere (this time the restart was immediate. No "system UI has stopped" message appeared). So i flashed another rom.. (silly me). I flashed a M8 HD Revolution rom because it was the most popular one and I thought it will fix all my problems. I flashed it successfully, the phone booted, it started optimizing apps and then shut down. I tried to turn it on again, it started optimizing apps again and after it finished optimizing ir shut down again. And that was the last time I saw my phone atleast trying to boot.
After all that I tried all the button combinations (vol up + power, vol down + power, vol up + vol down + power), Ive red alot and tried the same combinations with different timing. IT WONT BOOT INTO BOOTLOADER. adb and fastboot commands does not work also. When I connect my phone to a pc i was able to hear a windows connection sound, after 5-10 secs i hear a disconnect sound, after 5 secs it connects again, and disconects again ang again and again.... I managed to screen shot my device manager screen and saw Qualcomm HS-USB QDLoader 9008 in the device list appearing and disappearing every 10 secs. I googled it and found some info that I might have hard bricked my htc. I didnt have much time at that moment to dive into the ocean of information and decided to leave my phone connected to a charger overnight. NOW my phone is dead (100%). No flashing lights, no *connected/disconnected to a pc* sound, the screen is black, it wont turn on - no signs of life..
Is there anything that I can do? (the warranty is voided)
Could it be that the battery was damaged and it was the issue of my phone restarting all the time?
Any help will be much appreciated
*dont mind my english*

Are you s-on or off? Its very hard to brick this device flashing ROMs with s-on.
Try leaving the phone on charger for a few hours, then hold power+vol up for a minute or so. Most folks don't realize you have to hold the buttons for so long in this "no boot" condition, and start to freak out. I've done it myself!

Ive tried your technique, few times actully. Phone does not want to show any indication of life. I might have flashed the rom on low battery I just found out that the cable I was using to flash roms ir damaged and does not function properly. Now Im using a new power cable to charge the device but still, no signs of life.
Thank you very much for helping

I left my phone to charge overnight and the LED light came on (Its a really good sign). At first it was flashing orange, later it was only orange and now its green, so that means that my battery was fully drained. However, I tried holdin power + vol up for atleast 3-4 minutes but nothing happened except that the LED light is not greeen nor orange anymore. If I connect my phone to a pc, in the device manager "Qualcomm HS-usb qdloader 9008" shows up for 20-30 seconds and dissapears, after few secs it reappears again and so on. I was looking for a solution for a few hours and I think I found a decent tutorial how to unbrick it but Im not able to find neccesary firmware for my phone because I dont know my CID (link: http://www.droidsavvy.com/unbrick-qualcomm-mobiles/). Any other ideas?
BTW, thank you very much for trying to help

I've never seen these "unbricking" guides work on this device. If you can't get to at least bootloader, you are probably looking at JTAG, new motherboard, or new phone.
Really, your best bet is to keep playing with the button combos with the charger attached and unattached.
