Hi all,
I desperate need help. After an unsuccessful radio flash, my Desire won't even turn on. No response from any buttons or lights. Here's how it happened:
I'm relatively new to Android. I recently bought a Desire, to replace my Touch HD, which has seen about 25 different WM ROMs, over it's life.
I successfully rooted my Desire and had tried a few ROMs. I was sitting on the MoDaCo Custom ROM r17, which was all customised and running perfectly. I'd even used ADB to successfully update my wifi config to connect to my company LEAP-authenticated network.
I decided to flash the latest radio (32.37.00.32U_4.06.00.16_2), from this thread:
http://forum.xda-developers.com/showthread.php?t=687464
I entered Recovery using 'Fake-Flash';
I started flashing the radio image;
All the good messages were scrolling down the screen;
I kept one eye on the phone while I worked on my laptop;
I saw a message saying something to the effect of "Finished installing radio..." (sorry, I don't remember the exact wording);
The blue recovery menu had returned, with 'reboot device' as the default selection;
As I clicked the trackball, I saw another message appear under the 'finished' messages, which said "Writing rad " I guess it didn't have time to print the whole message, when I selected reboot.
The screen went blank then a graphic appeared in the middle (where the recovery exclamation mark and triangle usually appear), of a software box with a curved yellow arrow over it and the android icon peeking out from behind it. I left it for a while (already had that sinking feeling) then pressed the power button. It switched off and stayed there.
Since then, nothing that I've tried has received any response. Various combination's of button pushes, USB connection, removed SIM, SD and battery...nothing, not even an LED.
I've searched and haven't been able to find any solutions to this particular situation. Can anyone help, or am I totally bricked?
Regards, PF.
The radio update does 2 reboots to install it. The software box with yellow arrow is the default graphic used by the fake flash recovery as far as I know so that wasn't any real problem.
I know this might sound silly, but is the battery charged?

No question is silly under this circumstance!
Yes. I'd just taken it off overnight charge. 100%. If I plug the USB cable in now, there is no response from the LED.
Leave the charger plugged into it for about 5 minutes and see if there is any response to it. With the usb bricks it would take nearly 5 mins to register and the led to light up.
I know this isn't a usb brick, but I've not seen anyone with a failed radio flash that has caused the phone to totally die to the extent that it won't even switch on.
I take it you have tried the usual power and volume button combos etc?
I suppose if there is no quick fix for this, the fact that it's totally dead may go in your favour if you try to get it repaired/replaced under warranty

ok. The charger has been plugged in for 35 minutes and still no response.
Also don't want to sound patronizing, but have you taken the battery out and turned on with the back button helld?
Ignore me, just reread your original post.
the procedure u said sounds rite, thats whats ment to happen, when you flash a radio, only other thing that comes to mind is, sure the radio u flashed was for the gsm desire?
so what youre saying is that your phone simply doesnt turn on, not for a second?
if you press the power button NOTHING happens?
are you sure your charger isnt broken?
have you tried charging it through your pc?
have you seen if its recognised through adb devices on your computer?
have you tried a new battery?
if your phone is simply dead, it must be a hardware problem, in which case you can probably send it off for repair and not have your warranty void as the whole phone will need to be replaced. they cant identify if you have voided your warranty if your device doesnt turn on.

Right first time. It won't turn on at all. It doesn't react in any way to any of the button combinations I'm aware of from rooting and flashing it. Nothing happens at all.
I live in an HTC household, so I've tried a number of chargers and cables, including the PC's USB port. I haven't tried another battery...but the incumbent battery was holdng a good charge and was 100% at the time. What's more, I remember that the phone can run on the charger without the battery.
Not surprisingly, adb devices shows no connected devices.
I think everyone is right, it's back to HTC. I *hope* you're right that they cover it under warranty. I'm going on the weekend, so I'll let you all know the result.
Thanks to all for your help.
I think you can try to remove battery, leave the phone with no battery for 30 minutes and then try to insert battery and connect to usb without power it on to check if LED (and than the phone) is revived.
I had an Acer Liquid that gave me same problem, pratically when a flash on the radio go wrong, the device go in "protection mode". You must also check on the net if there is a protection mode on Desire too, and if there is a button combination to unlock it. I repeat: i just giving an idea becouse the same problem happened for me on an Acer Liquid, so i'm not sure if it's the same for the Desire.
Good Luck
Maybe a usb brick? No usb is no charging. So when you didn't had a full battery, it may be went wrong on that.
Try another battery, if you can get to one.

In the usb brick situation you can still charge. This isn't it!

Ok i didn't know that.
If the phone doesn't turn on at all, you can maybe try sending it back to the shop for replacement. Chances are, they won't be able to know what happened, so you can pretend it just stopped working.
If it gets back to HTC, they probably won't bother to figure out what's wrong with the phone and just give you a replacement. Otherwise, they'll just send you the phone back and you won't have lost much (maybe postage costs?).

Thanks for the suggestion. I left the battery out overnight. Then tried to activate it (all the usual button combos) with:
Battery out, USB cable plugged in;
Battery in, USB unplugged;
Battery in, USB in.
I scoured the 'net for anything on protection mode for the Desire...no luck. If there is one, it hasn't been posted yet.
I would just act stupid and try to return it under warranty!
I think it should be ok to RMA this, if its completely bricked there is no way of them knowing that you tried a different radio.

Yes, if it's totally bricked then just send it back to HTC and they will change it with no problems just same as acer done with my Liquid
All's well that ends well
Good news...
The HTC service centre were kind enough to replace my 'faulty' handset.
Re-flashed with r19 and radio updated (patiently) successfully.
Thanks all for your support.
Nice one. Glad it worked out for you
My Desire HD (original Rom, never rooted or done anything fancy) died while connected to a solar charger overnight.
- factory reset (volume down + pwr button) does nothing.
- removed battery, tried other battery, put it on a "real"charger, different cable, nothing works; the thing is dead.
- Charging light does not turn on (checked voltages, battery voltage, everything is good)
- The only thing it does, is register as "QHSUSB_DLOAD" when connected to my PC.
I suspect the charging / power ciruit got fried (it was a solar charger that I tried for the first time), but the fact that it had been charging fine during day (sun) and it died during the night, and the fact that it still does _something_ when connected to USB keeps me from throwing it in the bin.
So my question to you experts is:
Does the fact that it connects as QHSUSB_DLOAD mean anything promising for restoring it?
And if so, what would be the recommended steps for fixing it (preferably myself).
I've never rooted a phone, wouldn't know where to start (other than here), but I'm not exactly an idiot and there's a first time for everything.
O yeah, I've already voided warranty by opening it up and partially dis- and re-assembling it. I'm always amazed how many times that fixes a problem; though not this time...
Looking forward to some positive answers..
I believe that has something to do with accessing the processor chip and I don't think it's fixable without changing the motherboard. You could try sending it back for warranty repair and just hope they don't notice you've taken it apart. The don't always notice especially if all the screws/parts are where they should be. Good luck.

Buy some aftermarket void stickers, slap them on the phone and send it in for repairs.
How long have you tried charging it for?
Give it a charge over night and see if it is doing something in the morning (charge it on a real charger
Yeah, tried charging it overnight, but nothing happens.
Is there anything that can be done when it's in the QHSUSB_DLOAD mode? Uploading new firmware, for instance?
I bought a replacement phone (HTC One S), so I'm ready to experiment on my DHD..
Hi,
my battery ran very low (~2%), and I put it in a car charger, and used it for a call. I've heard of car chargers or combination of different cables etc. causing problems, but I think I can rule out a burned out motherboard, as the phone was functioning for the call and a text was sent after.
About 5 min after I took it out of the car charger (got home) I noticed that the capacitive buttons were lit. I tried turning the phone screen on, nothing happened. So I held down the power button for 20 seconds or so, again nothing. Then I held down the power button and volume down, and it went into recovery (twrp)
Not sure why I did this, but I wiped the cache and dalvik cache, and hit reboot system. Now at this point I don't know if the battery died, or if it tried to reboot and didn't work. Either way, it is now dead
I have tried the following;
Hold power button, no response
Hold power button, and volume down, no response
Hold power button, volume down and volume up, no response
Left charger plugged in for an hour, no response
There is no led light on when the charger is plugged in
I have tried connecting to a pc, it makes the 'new device connected' sound, and soon after, the disconnect sound. Windows states that the usb device is not recognised.
Any ideas?
Forgot to mention I'm on Slimrom 4.2.2 build 8 official
Is it true that the phone can't be charged while in TWRP?
Any help would be appreciated, I need to flash KK!!
Shameless bump
I have tried the script to get the phone to charge/ get battery voltage here;
http://www.hackmyandroid.com/comprehensive-guide-on-unbricking-the-htc-one-x/4216
Also, I have read that there could be a script to get the phone to charge, post #4 here mentions that;
http://forums.androidcentral.com/htc-one-x/300271-htc-one-x-will-not-turn.html
Can anyone pls help with this script mentioned in post #4??
I've rooted/ custom rom'd about 9 phones, I can't believe that it can be bricked by losing battery power while in recovery... nothing has ever gone wrong like this, please help!!
Try leaving it charging for ~24 hours
Try unplugging the battery from the motherboard and plugging it back in, if not get a new battery HOX is only about 5 pounds or you can upgrade to a HOX+ battery for about 20 pounds.
tried charging overnight ~12 hrs, no joy, but thanks
I have it opened up now, so might try disonnecting and re-connecting battery, thanks
I have been speaking to the team at TWRP on irc chat. Somebody suggested to strip USB cable back and connect bare wires to terminals of battery to see if it will charge. Will this cause problems as USB is ~5v and the battery is 3.7v??

I wouldn't risk the USB thing. You might as well get a new battery. I have a spare HOX+ battery which is 2040mah bigger than the HOX, I could sell that to you for a cheaper price than everyone elses.
I have since replaced the battery, and also a new power flex cable (that I broke during disassembly!) and something has changed at least......
Beforehand, Windows did not recognise the device at all, sometimes the 'USB device not recognised' dialogue box wouldn't even appear, although it would make a sound
Anyway, now it says that it's not recognised, but in Device Manager, it says it is a APX device (before it was an unknown device)
Can anyone shed any light on this?

Hello!
Well, I had the really bad luck of a very bad hard brick... my xperia was on low battery (around 15%) the last time that I use it, then around 20min later I got it and try to check, but screen didn't turn on, and the Led was blinking White color, since I deal in the past with this issues (around 3 or 4 times), I connect the usb cable to power adapter and simply did the reset button under sim flap, and my phone made the normal 3 vibrations, so, I hope that everything was fine, however, after that, I simply try turn on it, but never happen, No led of charge, no more vibrations and no power on, no signal of operation at all... so, I test remove and reconnect the usb cable and nothing, so, I try make another sim flap reset button test, but at this time and until now, no more 3 vibrations response and nothing else... and now, after reading some many posts, and try everything suggested in other posts about I really sad and hope for some help or feedback, if somebody may help...
By now I tested on my windows 7 notebook, and at first the phone was not recognized by drivers however it shows the bad message QHUSB_BULK error usb device, in later attempts, I made after some buttons tests looking for some response I got the phone change the messague, at the moment of connect it with usb cable to my pc, it was recognized as SEMC Flash Device... In both cases windows didnt allow or recognized for a proper driver installation....
But after other attempts, I lost the SEMC Flash Device status, and by now not remember what I did to get this mode or if it may be of some help...
By now I am really worry, since I got my phone from Hong Kong, and it came and worked fine until today, but in my country there is no service for this model since it not still on sale at official dealers/ carriers, and I believe that I don't have warranty service (since is an international purchase and not on local dealer) and also because I Unlock Bootloader for getting root and Sony records that information for warranty purposes (since I unlocked BL, I installed TWRP then I installed the romAUR custom rom and I upgraded it to 1.25 version with last kernel available from the same rom thread but thas was a month ago and phone worked fine after all custom rom installation)...
By now, I would like to ask if may be possible please, some guidance and help...
1) I was made attempts by the last 6 hours after brick without luck, and I wonder and suppose that the battery may be very low, but since I don't get any charging led, I wonder if by left It connected to the original sony charger with original sony cable (almost new and working both, and also tested both with other cell), my bricked phone may still get some charge on the battery.... somebody konws if possible to charge an xperia bricked?... I wonder/hope about that, if may be a charged battery may help in got the 3 vibes reset again that I hope may fix the issue and return my phone to boot...
2) Since seems that i don't have chance to get repair service on warranty since I unlocked my phone (and in my country the cost service for such model could easily be so high as almost a new phone), and also low chance for a warranty replacement from seller, I wonder about take the chance of open it and try to remove battery connector at a last resort since , I may suppose that this may allow for clear internal electrical charged registers of system and may allow me for a reset, but I wonder if the white flap sim buttons really did the same, that is simply open the battery connections, but, I doubt about that, since in this procedure the cel made 3 vibes and the energy for the vibes need to come form a connected battery...
3) May somebody with more luck, knowledge and experience, may suggest or share some help or advice about this issue...
I am a long time cell phone fan and long time in the issues of unlocking and installing custom roms, but until today, and after I survived many other phones bricks, my highest and loved phone of all my time, is bricked in a way that I am start to desperate, since I almost no clue by now about what could I try looking for a fix....
So, thanks in advance and if some body may help, I would be very grateful....
Is there really a reset button under the sim flap? Maybe you damaged the internals when trying this..

Yes, I've used it many times it's highly unlikely to damage it from that. Unless you press it harder than a gentle touch.

Yes, there it is, well, by now I am collecting more info and try about fully discharge my phone in order to get a RED permanent charging Led light (for future reference, seems that a Pulsing RED charging led means NO detection of battery...), by no today at morning I put my phone on charger and it only warn a little, and according with some info, the best chance by now is to plug it for a long time (other models of xperia reports around wait 24+ hours for get a RED permanent light...)
By now, I already purchased a set of adhesive gaskets, in preparation to open my phone (I did in the past and have some skills for doing it, but not that I really like to do over a so new and expensive phone... ), since by now, if I fail in got a RED permanent charging light, seems that the next step is to open back cover a remove battery connector, plug in usb cable connected to wall charger and then after 3 minutes wait, reconnect battery connector with the usb cable still attached, this would reset a really brick phone, and suppose tho reset the charging process of xperias...
By now, and in case of help other people that may need it now or in future, the guide that I am following advice is this:
[GUIDE] Recover 2012 and newer XPERIAs from SOFT-brick
http://forum.xda-developers.com/showthread.php?t=1849170
The info in the page seems with lots of sense, and the charging process description seems very similar at I would believe could be used in my previously Z2 and my now in comma, Z5P.... But by now, I need to get a RED light in order to try to unbrick without need to open back cover glass....
Any info, advice, comments or better, experience share, would be very gratefull...
Best regards...
Did you ever solve the problem? My Z5 died and wont turn on. Flashing lights when the usb is plugged in. Tried unplugging the battery and charging for hours
you have no fastboot ( vol+ blue led ) and no flashmode ( vol- green led )?
No, only a flashing red light when plugged in. The phone dos not react to any buttons.
Sony Xperia Companion does not recognize the phone.
"lsusb" in linux shows nothing when i plug the phone in.

I know you probably have but did you try holding volume up and power to force reset it?
You say you couldn't get a proper installation of hardware, so the computer can see the device? Is it showing an exclamation point next to the device driver?

Edit: Go to device manager and right click phone and do update drivers.
Click browse for update yourself and direct it to WINDOWS/INF folder and check "include subfolders".
Then click where it says "let me pick from a list of device drivers on my computer"
Then click Android phone from the list and click MTP USB driver and click OK for install.
Your phone should be installed correctly.
Then try fastboot etc.
Hey everyone,
I have an HTC One M8 that I threw in a box after I upgraded to a new phone. However, recently I've tried to pull it out to try to experiment with it, since it has an IR Blaster built in and I wanted to try making it into a spare remote.
The phone is refusing to boot at all. I've searched the issue and I've tried all the suggestions I've found: Letting it charge for a bit then trying to reset the battery, letting it charge overnight to try again, ect. Holding anything doesn't give me any response from the phone at all. While it's plugged in, the phone has an amber LED that lights up for a few seconds and turns off, lights up for a few more seconds, then turns off for a little while more before starting the cycle again.
If I try to plug the phone into my computer, it recognizes it as a 'Qualcomm hs-usb qdloader 9008', which from more searching tells me that the phone could be bricked... but I've never tried to flash anything on this phone. It should be running stock Android. I don't know which version of android since it's been in a box for so long, but I'm about 95% sure it's stock.
Is the phone just entirely dead from sitting in a box for a few months, or is there a way to salvage it?
There are 2 options: Your phone is hard bricked and maybe it can be repaired, maybe not.
Or your battery is dead and need to be replaced.
How does a phone brick itself by being in a box for a few months?
Are those the only two options? Either it's dead or dead?

Make sure you charge with wall charger (not connected to a computer) and try another charger and cable. Charge overnight, and then try holding power+vol up for a minute or more. The last part is key in the current situation. I've seen a number of folks (myself included) that freaked out that the phone wouldn't come on, when we just needed to hold the buttons longer.

The Qualcomm "download mode" message (when plugging the phone to computer) will come up if the phone is bricked, but that is not the only situation that will give the Qualcomm message. This message will come up, whenever the phone is powered off, even a perfectly working M8. No USB interfaces can connect when the phone is powered off, that is all the message can conclusively tell you. That can be from a brick situation, or low battery, or simply if the phone is turned off.

The battery won't take a charge, if the voltage is allowed to drop too low. Usually, there are safeguards to prevent that from happening. But it does happen in some circumstances. Leaving it powered off for a long time can be one of those circumstances.
If charging overnight, and holding power+vol up doesn't show any improvement, you can try taking it to a repair shop. Some shops have special battery chargers that have a "boost" function, that can get the voltage high enough the battery "bring it back to life". But they may need to take the phone apart to do this. At that point, you may as well get a new battery.
