[Q] QHUSB_DLOAD: How to unbrick ?

I have bricked my phone while flashing RUU. My phone didn't restart after flash. It doesn't charge and also doesn't respond to long press key combination.
Now when I connect to computer the driver doesn't get installed. Error is "QHUSB_Dload missing".
I found that it is a Qualcomm driver used to identify the CPU serial number and establish any communication with my phone.
How do I unbrick ?
Do I need the JTAG method ?
Can a HTC service center fix this ?

Hi, sounds like a problem i encountered
after hours of digging and end up with not much..i put up a trick that actually worked for me(over and over again for me,cos my H0s keep entering qhsusb_dload mode each time i restart my phone.
u have to take apart your phone, get a torx T5 and a philips screwdriver(search or see at youtube how to take apart your phone.
just take apart the back cover to reveal the mainboard
-disconnect the battery
-connect the phone to charger(charger,not pc/usb)
-keep an eye on the notification led, it will light up(orange) for a couple of seconds after u connect it to charger,then went off
-after the notification led went off, reconnect the battery and pull off the charger from phone.
-(dont reassembly the phone yet)press the power button a few times to see if it will boot, or you can hold the power button for a 10 second.
-in my case,at this point the phone should be booting,but to a bootloop.
-i suggest you enter the recovery when it boots up and do a full wipe.
Try it,do tell me the result please, i hope it will help and do it safely, carefully because anything that happens, i ain't gonna be your warranty desk

I guess this method assumes that the battery has some charge left. Mine doesn't. I tried no result :crying:

I dont think it matters..when you are flashing the ruu how much juice you got left? if u start flashing when the battery is around 100% im sure there should be enough charge to at least turn the phone on..can you tell me more why it didnt work for you? what you went through?

Nothing happened when i connected to charger. No LEDs lighting up.
I think my battery might have drained completely.

Does your pc detect anything when you plug usb cable ?

Yes, it detects, but then disconnects, can it be a problem in the battery?

Chances are you have received a refurbished device or defective battery.
Try and find another Mi4 user for trial of the battery or let's see you need to contact the vendor soon.

Charge via wall adapter. Leave it for some time.
PS: When your battery reaches 9-10%, it is advisable to charge it back to 100%.

Hi,
Im having the same problem, Red LED when charging, nothing else on screen, cannot switch on, its not even detected when connected to pc.
were you able to solve your problem?

I just got this issue 10min ago. Havn't depleted the battery on the phone for a very long time, my guess is that it hasn't calibrated the battery in a while or something like that. Will keep it in the fast charger during the night and then i'll reply here.
EDIT: Normally the red LED is constantly on when the battery is low and it's in the charger, now it's flashing which makes it look a bit more scary.
EDIT2: Works fine now after a night of charging

Charger could be not pushing enough voltage to charge battery. Try another one to see if it remedies the issue.

I do have the same problem with my Mi4. I wanted to start the update in the Updater app (to Android 6 version of Xiaomi.eu) and suddenly it turned off (at 100% battery). When I connect my phone with my computer it is recognized and all the partitions are mounted. And with all I mean all. There are about 7 partitions mounted (Linux and Windows) and they keep being mounted until I disconnect the phone. I let my Mi4 on the wall charger for 24 hours (2A Samsung one which charges all my other devices without any problems) but I still have the blinking red light after connecting it to the charger. Any other things I can do to get it running again?
EDIT: I can't see the phone in fastboot or adb and when I keep the power button pressed for about 10s it seems to disconnect and instantly reconnect the phone.

I solved this problem on my own. Even though the phone doesn't show up on the fastboot devices list you can use the Mi Flash Tool to flash the fastboot update (http://xiaomiadvices.com/miui-7-flash-fastboot-rom-on-xiaomi-phones-using-mi-flash-tool/). The drivers installed with the Mi Flash Tool for the Windows 10 Mobile Release (http://en.miui.com/thread-189369-1-1.html) recognize all the partitions as one device and show it with a cryptical name in the flash list.

Hi ! I fully charged the phone and after it shuted down. It doesn't starts. PC doesn't see it. When I'm plugin the wire just half way into the phone the red light stays on for a few seconds and than nothing at all. Can anyone help me?

Push power+vol up for quite enough lets say 20 sec

same problem here i kept charging for whole night but phone not getting on.. only red LED comes when kept for charging and not detected in PC also. Can any 1 help on this

I had the same problem ( strangely,it occured after a whole night charging, f... knows what happened)
Tried to change charger. No luck. The phone won't even boot by pushing Vol down+ Power
Solution: I simply connected the phone to a portable external charger, and tadaaaa !!! it was brought back to life !
Hope this helps

Is my Nexus5 dead or only its battery?

Howdy!
My phone doesn't work anymore, and I try to assess what's going on. I searched before posting, and I decided to post here because I found mixed answers.
Context:
I bought my phone in January 2014. I took extra care of it, it has never fallen on the ground from high, no scratch, nothing. Regarding the battery, I tried as much as possible to charge when it was close to 0%, I wasn't a heavy user of my phone, and I was turning off a lot of things so that the battery would not deplete quickly (Wifi, localisation, Bluetooth, auto-typing, et cetera...).
However, recently (the last month), I was feeling the battery was weak, depleting more quickly than before. I also felt the phone was warmer than usual. Sometimes the phone would turn off suddenly when I was short on battery (under 15%) and using a "heavy" feature (photography with flash, video game).
A week ago, the phone suddenly turned off, never to turn on again. The phone died. I was just typing a message, the phone was charging and the battery was around 60%. I was surprised.
As of today, the phone doesn't turn on. Plugged on a wall outlet or on the USB port of my computer is the same.
I tried many combination of buttons to fastboot, reboot, reset, or whatever, nothing sparked any life in my phone. (I tried holding power key for 30s+, 15s+ ; I tried holding power key + volume up for 15s+ ; power key + volume down ; power key both volume ; in fact whatever combination I could read here on XDA forums, on Reddit, on Google Forums...).
My first insight was: it's just the battery. I can buy one off the internet, and voilà!
However, when I plug the Nexus 5 on my computer via USB, the computer reacts with the sounds when you connect something. Is it just the battery then?
At first, it was saying: "QHS_USB BULK", and the computer was trying to install whatever to make that peripheral work.
When it was done, it read "Qualcomm HS-USB QDLoader 9008 (COM4) has been correctly installed.
Hum, okay.
Still, nothing shows in the peripheral.
I continue to hear the plug in plug out sound when I... plug in and out my phone in the computer, but that's the only thing.
With all that, I can't really tell if all the phone is dead, something grilled inside or I don't know what; or if it's just the battery that is dead and the phone is unreachable and unrecognizable when "there is no battery" in it.
I'm not sure if I shall invest money into buying a new battery.
Do you guys can light my lantern on that matter?
I would greatly appreciate it.
Thanks,
Cheerio!

If I may just address a little bump on this very subject of particular interest to myself :3
Cheerio!

Any insights on this? mine´s doing the same. Doesn´t turn on or go into bootloader, when i connect to charge it red light blinks for like 10 sec and then goes off. Nothing happens after hours of charge.
Did you try replacing the battery as you mention on the post?

Sorry, but have to say this with caps: BLINKING RED NOTIFICATION LED MEANS ITS DEAD BATTERY. Can't be 100% sure, but usually it means that the phone doesn't have enough power to boot up. Mine did this when it drained to the absolute 0%
edit: There can be other problems with power going to phone, but if you are lucky its just the battery.

So i changed the battery. When i plugged it to charge no red lights came on, just the typical white battery with the light bolt appeared for a few seconds, after that it went on with screen off (or at least i thought it did). After 3 h of uninterrupted power charge i went to turn it on. Nothing happened. Can´t turn it on or go into bootloader.
Nothing happens on my pc when i plug it. No sound and nothing on Device manager (no drivers for nexus 5 installed, don´t know if that matters for windows to recognize it as any device even if its not as android device).
Edit: yeah, i got enlightened and literally unplugged the battery and plugged it back in and it worked like charm. I get stuck on the intro animation but i can get into bootloader and recovery just fine. Just gonna install those drivers and flash something. right? Thanks to everyone that read and even more to those who replied!

Yeah, search from youtube how to flash factory image nexus 5. It should make it work. And try to find video with using adb instead of toolkit, adb is way more stable/trustable. (ADB is the android debug bridge, it may look like very hard and confusing but in the end its just typing 1 command and it flashes everything needed) If you need help in flashing the image, just ask!
Try this, it installs only tools needed for adb (also drivers) http://forum.xda-developers.com/android/software/tool-platform-tools-adb-fasbootdrivers-t3061441
Edit: This should work https://www.youtube.com/watch?v=5ka5dnPghzI

Sudden Death Z3

Hello all,
For some strange reason my phone died on me friday, the last time i saw it on was while updating.
It wasn't charging at the time so i thought maybe the battery ran out, but when i connected it with the charger my phone wouldn't boot correctly.
My Z3 was in a bootloop, it could still be detected by my pc but i couldn't do anything due the fact it was turning off and on all the time.
I tried to enter recovery mode but it instantly restarted itself...
Pc Companion wasn't detecting my phone so i couldn't use that.
since my phone did get repaired already (my screen broke) i could manually disconnect the battery but that didn't work either, i tried a new battery too but to no succes.
I also tried all the button combinations, the only mode i could enter was fastboot mode (blue led) and it would stay on but still no sign of a normal booting process.
The yellow button near the sdcard slot didn't work either.
When i put my phone to charge at the wallsocket the led stays red and it won't reboot all the time, but after 15 minutes the red led disappears and it seems like the phone isn't charging at all.
Today it got worse, my pc can't detect my phone anymore and the bootloop stopped too, the led stays red when charging (usb and wallsocket) but after some time the led disappears.
I can't enter fastboot mode anymore.. plainly said; nothing works anymore.
Anyone knows how to fix this problem?
Sony doesn't want to repair it for me since i fixed my screen externally so i hope for solution

I had a similar behavior on a Xperia T when my battery was deeply discarged.
There was No way to load the battery inside the phone.
The phone has to start the bootloader or something like a "mini kernel" (dunno how it is called exactly) to start the loading sequence.
If you are under the -normally not reachable- minimum volatge (under normal conditions phone turns off before) there is too less juice to turn on the booloader and start the loading.
In my case I opened the phone put out the battery and charged it directly with a power supply by wire.
For me it worked.
I see you write that you tried other battery was this one full for sure.?
regards

I assume that you know that... but nevertheless
I advise you to be very careful with li-ion batterys the
are very sensitive with charging voltage.
There are some tutorials on youtube but do it on your
own risk I´m not responsible for anything...just saying.
Edit: for safety...I think it would be good to try to load the
li-ion battery only that much that it has enough power
to boot in the loading state...then put the battery back in the
phone and load it the normal way.
I wish you a succsessful charging let me know if it worked.
good luck :fingers-crossed:

What i am about to say is assuming that youve also tried to get the phone into download mode with the correct button press combo without any success
if the phone is going to be recoverable by methods most normal xda users are able to physically do, then youre going to need a couple of things. First and foremost a charged battery. If the battery drained so much that it wont even boot anymore, then we wont be able to help much past that. If the battery is charged, but the phone still wont boot, then you might want to try a USB Jig. Amazon link to show you an example of a Jig. Jigs look like the end of an older style charging cable but without the actual cable part of it. They have jumpers in them shorting out 2 of the pins inside the connector which causes the phone to boot into download mode. You can make your own Jig if you cant locate one to purchase with this tutorial. That should get the phone into download mode and from there youre in a really good position to fully recover the phone to how it was before it crashed. Be prepared for the possibility that the phone is actually dead tho
