[Q] HTC M8 unbrick help

hello everyone.
Can anyone help me with unbricking my M8?
Its a live , its reacting on usb connection with my pc, but i can not communicate throug usb, i can not see anything on the phone screen, i can not get it in recovery/bootloader netiher download mode,

yes
Yes its possible.
Open device Manager in windows. Plug in your device an you must see for seconds a new device named qhusb.
You must be fast and right click on this for seconds pop uped device and click properties.
Then look for the Qualcomm bootloader driver With google.qhusb driver.
Then install this driver with the opened properties settings.
If you get this, make a post here.
Good luck.

Hi Konsolen,
Thanks for the reply. I connected the phone, and qualcom hs usb showed up and i have added some screenshot , but i dont exactly understand your last comments qualcom bootloader driver and so on.

It looks that your Windows install it automaticly.
Are the device always in the device manager or only for seconds?
I will upload some tools in my dropbox and send you a link with infos.

Does the M8's screen come on? Any charge LED (and what color)?
Very key detail (among others): what did you do to get the phone into this condition?

m8
the notification light flashes for a second when connecting to a charger. it flashes also when connecting to pc. also flashes when holding power butt for 15sec.
i installed cm12 but i couldnt use my navigation as the ohone couldnt find any sattelites.
so i tried several firmwares and after changing to supercid i managed to update firmware and hboot. after installing cm12 the phone asked me for a password and i found the installation was corrupt somehow. i find some commands i typed in recovery twrp but it freezed and after a forced restart i saw red triangles on each corner and has never seen anytging on scrreen since. always black.

That is remarkably vague. What commands exactly?

​
sorry, the color is orange.
i'm on phone now and can send the commands i have tried
but the codes never worked but i believe i managed to delete a wrong partition .
when onnecting Phone to pc, 14 disk partition shows up, only 4-5 of them has files inside.

Device is always in the device manager. If i remove the driver it shows up as qusb bulk with question-mark.
I tried to download several driver but i couldnt get the device in fastboot or download mode.
I look forward to your link
Thanks

TWRP after installing a rom giving me "unable to mount data" all the time.
I done a research and found out that i could type following commands and get it work.
cd /d c:\mini-sdk
adb push mkfs.ext4 /tmp
adb shell
chmod 777 /tmp/mkfs.ext4
/tmp/mkfs.ext4 -b 4096 -O ^huge_file,^dir_nlink,^ext_attr,^resize_inode,^ext ra_isize -m 0 /dev/block/mmcblk0p37
But i heard from somebody that these codes were for HTC M7 and not M8

What carrier or region (CID)?

Why not just try and flash the RUU?
http://forum.xda-developers.com/ver...zip-ruu-m8vzw-5-0-1-s-off-onlynewest-t3047103
That might at least get it working again, as you can do it via a microSD card

m8
i have now downloaded the standalone zip and copied that to sd card, renamed to 0P6BIMG.zip
as the screen doesnt show anything, i have powered on with vol down, i assume the hboot ask for vol up for continue to installing, now i wait but i dont thing anything happens
The exe RUU says "USB error, could not connect to the phone"

When connecting the phone to pc, as said before 14 disk partition opens up, and here are the folder which contains the files showed

When the phone connected to my pc , its shows in device-manager:

Ah, right. Yeah you've bricked the phones internal memory. Not sure if it's repairable but if it is it's WELL over my head...

Screen not coming on, and device showing as Qualcomm on PC is a bad sign. Agree it might not be recoverable.
Someone did the same thing (M7 internal storage "fix") a week or 2 ago. I'll see if I can find the thread, and if there was any favorable outcome.
But extreme care needs to be taken before manually messing with partitions like the OP did. A single mis-typed character can be disastrous. And there are safer ways to have recovered from the fairly common internal storage issue (format with computer or in TWRP).

[SOLVED] Can't Enter in Download mod / no boot / no Recovery

Hello,
So i am in BIG trouble right now.
i just flash my lg g3 D852 to stock firmware using LG Flash Tool. and after i setup my phone i reconnect my device to pc but i forgot to close that tool. and suddenly it start processing and then i remove my device.
so now basically my Os is gone, i can't go in download mode, i can't go in recoverymod either. and also phone is not connecting to pc .
any idea how can i fix that. PLEASE i need a solution ASAP.

You should wait the process to finish, unplugging usb cable is the cause. Now please tell me what you see in your device manager under ports tab, or as an unknown device when you connent your G3 to PC again ?
Use these drivers to identfy your new port then we will continue from there.

There is few things going on.
i already installed the drivers you gave me. after that.
1) when i connect g3(with battery) to pc with usb cable - it shows me nothing. and its keep restarting the phone.
2) when i connect g3 (without battery) to pc with usb cable - it shows me this

and also last thing. i dont even need to press power button when i connect g3(with battery) to my pc. it just turns on automatically and start restarting again and again.

I asked wrong question in first place, i always assume "dead" brick phones when i hear "no download mode, no recovery", so your phone powers up but in a boot loop, all your boot partitions are lost, corrupt, including bootloader and laf parititons ( recovery and download mode ). There is a fix for that too, now second question, can you open your G3 ? I mean tear down to mainboard ? Becouse if you can do and shortpin two tiny spots, then we will have our necessary Qualcomm port to go on and start the rescue mission.
A little reading might help too, the schema of these two magic spots is in this article , please take a look.

NO no ! Just a couple of screws, just hold up the back plastic part thats all, youll see the mainboard there. Sorry my mistake, not tear down completely.
After if you can manage to shortpin we will use LG's own BoardDiag to restore boot partitions, and your phone will be ok.

If everything goes well boot partitions will be fixed, if emmc passes the test but still no fix then we will try my fix, but boarddiag mostly handels these situations itself.

Of course i did tried myself, still fixing many G3's this way. I never say or write things without experience (without trying it myself before). I know this is a dangerous method, but its an upsolute fix what can we do ? I wished that LG did chosen Qualcomm port for repairing, but no, to gain more money from their customers in its own service centers ( mostly charging for motherboard change ) LG choose to hide that port, so here we are, hacking it internaly..
Im sad to hear your accident, no mobile repair shops in your town ? Its not that hard to fix it indeed..

thanks again very much for replying that fast , means to me a lot by the way as i feel i'm in a crisis
but everything works fine even after the dislocation of the capacitor , except the damn usb error that i get when i connect the phone without the battery , will try to short the pins for 3 mins cuz i only shorted them for 3 seconds (LOL)
i will try again and tell you if this capacitor ruined something or not
and yes i will try to go to an expert to put it back
thanks again hope i fix it so my mum can be proud (lol)

No OS, OTG not recognized. Am I bricked?

Accidental full wipe of my Nexus 7 has left me with a no OS paper weight.
Fastboot indicates it's locked but I can boot into TWRP, but can't get it to be recognized by any PC and it won't recognize my OTG-USB (which has been recognized by others).
Any ideas as to how to get her up and running would be greatly appreciated.

Did you mount the OTG usb in TWRP or just looked for it to auto detect?
Btw, this belongs in the Q & A section, so ask a mod to move it

I am unable to select/check mount the OTG while in TWRP. The OTG is formatted correctly as the OTG is readable on other devices, but it seems like it just isn't being found by the N7. I'm baffled.

Tried it on a full battery, still no luck.

tried to get it to work, any suggestions fellow XDAers? I'm in a real jam here

I am able to fastboot, but still can't get the pc to recognize that it's connected. The tablet takes a charge, but the pc never acknowledges that a device is connected, device manager never indicates a device is connected.

-If you don't have any Roms on internal storage, that's no good since you have TWRP.
-Try A different USB cable.
-Definitly make sure you have installed Google USB drivers.
-Have you tried ADB Sideload in twrp? Maybe TWRPs' adb will work better.
It looks like you need to update your bootloader as well, go with the latest factory images.
If you need to know where to find the above things I can point you to them. You must eventually get the PC to recognise it in fastboot though.

Thanks. Everything hinges on the PC being able to recognize that I'm attempting to connect the tablet (or for the tablet to recognize that I've attached the OTG).
I have tried multiple USB cables and ensured that the drivers are installed on the multiple PCs I've attached to.
I have tried to ADB sideload in TWRP, but since none of the PCs recognize that the tablet is connected to the PC, ADB won't work.
Again, it's not that the drivers are not installed, but rather the PC not recognizing that I have attached a device through the USB (no sound, no pop-up, nothing in the device manager). It is extremely frustrating, especially since the device charges via the USB from the PC.

Device Manager doesn't even show something like "qualcomm_qloader"? That's seems worse than any other hard brick I've seen.
-OTG should be FAT32 formated (probably is).
-We're you using Lollipop with that 4.02 bootloader? I believe that was A prerequisite for installing Lollipop which may have cause the tablet to not show on the PC.
- Nexus Root Toolkit has different methods for installing drivers http://www.wugfresh.com/faqs/
-Found this thread http://forum.xda-developers.com/showthread.php?t=2404297&page=1
Shows holding power for A minute got theres' to start doing stuff. It' A different recovery issue though.
Hate to be A downer, I hard bricked A galaxy s4 I had for only 5 days last month. That never turned on again. It's not fun.

I had the same issue. The only way I could fix was a full adb restore. I tried several other ways and none worked.

Nothing shows in the device manager. I was using KitKat on the tablet.
Turns on without an issue, opens TWRP with no issue.
when connected to the PC nothing occurs, not when it's on the Google screen, not when it's in TWRP, not in Fastboot, not when it's restarting. Nothing.
if it was the driver being missing, I'd at least see the device attached, just not communicating properly
sorry to hear about your GS4

if you truly had the same exact problem, how were you able to use ADB if your device wasn't recognized on a PC or OTG?

it's alright, thanks for the thought.
I'm just hoping since I can get into TWRP someone has an idea of how I can get it to recognize the OTG or the PC to see it and I can get into ADB.

Corrupted usb port on the tablet? Maybe broken pin. Try to examine it. It can happen that it is being charged but not identified by the pc because of a faulty port. Try live install of ubuntu to chech if it sees the device.

the port looks perfectly fine, I was thinking the same thing, but there doesn't seem to be any damage. I almost wish it was damaged so I could at least assume that's the problem and just trash the thing.

thinks i tried:
1. Install oneplus driver
2. Install ADB drive
3. Update driver from device manager

Instal ADB 1.43. It contains drivers for windows. When ask install them too.

I had similar issue about 2 years, when I had Oneplus One. Eventually it turned out it was coz windows 7s driver recognition went kaput, because some local usb device messed up windows 7s driver recognition

I am also having this same issue.., I am 100% sure it's not driver issue. I've tried in Linux PC., Even QCom Diag mode (to use unbrick tool) doesn't work... Only I'm able to charge phone at USB speed. Dash charge as will as OTG doesn't work. I even got a USB-C port replacement and still am having the issue. Last week gave my OP3 to OP service centre they also confirmed some issue in board and can't be fixed without replacing entire motherboard (Stupid folks!!).., I'm rooted and on Oreo.
Any leads/advice on this issue is much welcome...

I've visually inspected MB and found no clues of burnt components.. Also OP3 is one of well-built phones hence I suspect H/w issue in the last place..
Just because of my wildest dreams I got into this prob after Oreo OB fw update, (I remember I was dash charging that time) Can firmware files interfere USB data port interface?? @jamal2367 Pls provide your guesses...

Hi Guys,
Update on this thread:
Since I got no response, I was somehow managing with my OP3 but now this issue has grown like blocker for me. Now despite connecting with PC, Charging line is also not working properly.
So, I connected to charger last night. It charged only till ~70% and phone was fully heated up. I tried reconnecting charger and phone doesn't show its charging. Then assumed some cable/charger issue and continued using. Evening when I connected back, it was charging but dead slowly. Like from 20% to 50% in 3-4hours! So, this deems phones as almost dead, forcing me not to use it any longer. Pls help with any suggestions to resolve this...

I am having the same issue if anyone found any fix please let me know

I'm having weird problems with the PC to USB connection on a oneplus 3. Im trying to get it to recognise so that I can flash it back to stock, but my PC always gives the "the last device malfunctioned" error and it always shows up as "unknown usb device (device descriptor request failed)"...
This happens in MSM bulk mode, fastboot mode and even in recovery mode. Tried it on a windows 7 and 10 pc, no dice, can't even install the driver. Tried a different cable too. It works completely fine on another op3...
Replacing the USB c port didn't work either. Has anyone had a similar issue? Charging works fine...
I'm hoping it's somehow a software issue because otherwise it's looking like a mainboard issue and these seem quite expensive to replace... so any tips or advice are very welcome
Thanks already

Try a different usb cable. I was using an anker usb c which finally worked. Got an original dash charge and it craps out. The usb c port on our phones is just weak compared to modern phones. Mine is giving out slowly and gradually after more than 2.5 years and I have to angle the connector at times for the charging to start. Guess it's slowly dying

It's not the cable. It works fine on another phone and I tried a samsung and anker cable....

My particular issue was similar to ROKLAF here in this thread
thread
my phone entered Qualcoomm crash dump mode after flashing pixel experience. When connected to USB it would show up as "USB Device Not Recognized".
MSM downaloder tool also does not recognize my phone
After updating
Qualcomm HS-USB QDLoader 9008 Drivers - FOR THE 64-BIT ARCHITECTURE : https://www.mediafire.com/file/5wc5nk5adevatrj/QDLoader_HS-USB_Driver_64bit_Setup.exe/file
Qualcomm HS-USB QDLoader 9008 Drivers - FOR THE 32-BIT ARCHITECTURE : https://www.mediafire.com/file/q1uynnim8arbim9/QDLoader_HS-USB_Driver_32bit_Setup.exe/file
OnePlus Drivers - https://oneplususbdrivers.com/#choose-device
I pressed the volume up and volume down and power button for about ten seconds, oneplus fastboot logo shows up, then it boots into Qualcomm crash dump again.
After this step, turn off the device using volume up and power button for ten seconds
and immediately pressing volume up and volume down button I was able to sucessfully register my device on MSMDownloader tool and unbrick my device via a fresh install.

MTP options do not show when connected to Laptop

Hi All,
I hope someone here can help me with the issue I have been facing with my LG G7 from the last two weeks.
Earlier my phone used to show me the MTP options each time I connected it to my laptop using the cable. For some reason, the phone does not show me the MTP options anymore and only charges when connected to the laptop.
I have done the below to try & fix but nothing has helped.
Cleaned the charging port on my phone
Tried a different USB cable
Tried USB debugging
I also did a factory reset on the phone
While researching on the internet, I read about the three dots on the storage tab, I don't have that. Also in developer options the Select USB configuration does not pop-up and when I click it 5 to 6 times a window pops-up and vanishes in a fraction of a second.
Any leads on what needs to done to fix the issue I'm facing?

Hi.
Go to C:\Windows\INF\wpdmtp.inf, right click the file, then click 'Install' in the menu. See if that helps.

No Luck.

Hi Romkeris,
Thanks for the tip, tried that with both the phone connected to the laptop and without the phone connected to the laptop and it did not help.
Any other suggestion that you want me to try?

That helped me, with same problem some time ago. Also take a look at device manager if there are no devices with the exclamation mark, when you connect phone.
If there is, delete it and do the same as in my previous post. Also you may try to install latest LGMobileDriver_WHQL_Ver_4.4.2.exe.

Hi Romkeris,
Thanks for the additional tips. They did not seem to resolve the issue.
I do not have any devices with exclamation marks in my device manager and I have installed the drivers as suggested too. I have also tried using a different laptop and a different cable but both yielded the same output. Just to confirm if it not my laptop, I tried connecting my Pocofone F1 and my laptop was able to detect that but the laptop fails to detect the LG G7 with the same cable as well.
To mention again, I do not even get the MTP options that android devices get when they are connected to computers.

If you can, backup your important documents and try to reset Android to factory defaults. Its seams, it is G7 fault. I think it has big chance to resolve that issue.
This time is the only option I can suggest you.

What did you do with phone before that happened? Is this stock Android?

Hi Romkeris,
I have done nothing actually. It's not rooted and is running the OS that came with the phone.

I have no idea when it stopped working as I don't use the option that often but is must be after some update from LG? I don't know much about this stuff but think the only way to fix this is by LG update or patch?
Also strange that while searching for a solution it's as far as I know just us two having the problem?

As you describe the issue seems to be a physical failure in the USB Connection, do you have noticed slow charging or quick charge failure? Any notification about any USB concern? recent moisture? if yes I would suggest replace USB module, If warranty is not an option, ebay is your friend, go buy the spare and replace it.

I had issue with usb debugging being enabled. Sometimes disabling it helps. Sometimes going from mtp to ptp back to mtp. Or just installing the "standard MTP-device" driver on windows. I had an issue also because my windows was a KN version or N version. You need a media pack thought that didnt help me. I had to install a fresh Windows 10.

Thanks, Smariob.
I think having the USB module replaces may be my last resort as I have tried literally everything apart from this. It was a pain in the A** to have close to 100 GB of data transferred over a memory card as I did not have access to move data directly from the phone to the laptop. Formatting the laptop too did not help.
Thanks anyway, for all your suggestions!

Does this mean I'll not be able to root my device or run adb commands from my PC to the phone?

I have the same issue. I have tried factory reset, using a different charger, and all the other steps listed in this thread. If you have found any solution please share!

these two thing are totally different stuff
imho mtp is terrible and sometimes i've lost files, if the phone is ok the problem is in windows, and 90% times is windows problem.
now if i need to transfer files i use lan wifi with a good file manager, like mixplorer (is buggy but wifi transfer works so far) or any other famous file explorer with samba support.
OR remove sd and use a card reader to be 100% sure.
mtp is really disgusting.

Did you ever find any solution? I replaced my usb port and the problem still continues. I think it may be something with the android software itself and I cannot find anything on how to fix this problem.
