Desire Z wont power on :(

Hey guys,
Running ILWT CM7. Flashed about two weeks ago. My phone has been working fine except for the past few days where it's been constantly freezing, requiring a battery-out and turn on, and rebooting on it's own.
Last time it froze, I removed the battery and turned back on, and it got to the "htc" logo and froze. After ~25minutes, I took the battery out and tried again.
Phone seems completely dead, won't respond to power on, volume down and power on, no lights come on when charger cable is plugged in. When USB cable is plugged in and no buttons or anything on the phone is pressed, my laptop attempts to install drivers.
Tried leaving battery out for 30minutes and trying again, but no luck.
Any suggestions?
Cheers!

Stuck in RUU mode?

Looks like your phone is stuck in RUU mode.
In RUU mode you see the silver "HTC" logo as long as your phone is connected to your computer with an USB data cable. No charging lights will show in this mode.
You can use the following command to boot your phone to Android:
Code:
fastboot oem boot
When that does not work, because your partition table or system partition might be corrupted, then you would have to use the correct RUU (Rom Update Utility) for your phone to get it back to a working state.
When you have a bricked internal memory chip (emmc) than nothing will work properly to restore your phone to normal working conditions.
In the case you have an engineering HBOOT you could boot a ROM from SD card, but that is a far shot.
Best regards,

Thanks for the help
When plugged in with the USB cable -> computer, I still get no response from the phone itself. Screen doesn't turn on, still seems dead. My laptop still says "Installing device driver software" to no avail, and phone is still dead. No lights, screen is off, nada. As though it was powered-off.
ADB Devices lists nothing, and fastboot oem boot hangs on <waiting for device>.
Am I out of luck? I could send the phone off for repair, but as I'm rooted I think warranty is void.

Windows seems to need a driver installation for using fastboot. Did you try to automaticall install device driver software? Have you installed HTC sync on your Windows computer?
When your device does not respond at all, and even refuses to connect in fastboot, then nobody can tell that you have been rooted.
Best regards,

Sounds like your EMMC is fried, as of now I don't think there's a solution other than sending it back. Many say HTC accept and fix it even though it is s-off

did you get this worked out? i had a similar problem, ended up booting into fastboot by holding the trackpad and the power button, then just selected reboot and my phone powered on like nothing had happened, i was running the same rom.

Hey, did you alreasy tourned your phone to the fastboot mode?
Or does your device still have a black screen during boot?

I rooted this phone and when I was done trying S-OFF, phone would not respond to anything. It would only blink the orange notification light when I pressed Power and Vol+, or it would stay steady green with both Vol keys and Power. But the phone screen would never turn on. So after trying for hours to figure it out. I finally took the battery off, plugged the phone held pressed the power button and then put the battery in place the phone finally turned on and it worked. I turned the phone off again and it was doing the same issue. So I did the same step but this time with power and vol- to get in the bootloader and changed the hboot version to Desire Z. After that phone works perfectly, turns on and off with out any issues.
I did have to try the trick a couple of times idk why but it would work once in a while not everytime i tried it. Hope this helps anyone who also ends up with a similar issue.

Dead Lg G3

So I bought a used G3 knowing about the issue it had; it didn't boot. I thought I could find a workaround to this but the phone doesn't boot, doesn't enter recovery or download mode. All the info I have is that when I take off the battery the pc sees it as an unknown device, while it's connected I press the power button for several seconds and it disconnects from the pc, reconnects after several more seconds of pressing the power button. Screen remains dead. Seller told me he had a perfectly working phone before he tried to root it and it never turned on again. One more indication is that the LED notification only flashed red a few times when I connected it to the wall charger and that was it. No LED working after that. I'm open to any suggestions though I guess I'm here for someone to tell me there's no hope reviving the device. Thanks in advance!

Same proble with mine but i bricked mines when update to lollipop and never turn on again . still waiting to some one help to revive my LG

If I come across any solution I'll post it here. In the meantime I've tried the following method on a freshly formatted laptop and I still get "Unknown Device" in Device Manager..

same here
same problem, someone told me that if was the board or something like that and that it only can be fixed with a complete replacement of this, also, that it could be fixed with linux using comands to install .APK or .TOT.
linux sometimes sees it as Qualcomm CDMA Technologies MSM QHSUSB_BULK, using a virtual machine of linux ubuntu, windows 8.1 sees it as unknow device
LG dead since 3 months ago.................. i wasnt using the phone at all when this happended so........... :crying:

I tried using a boot usb drive to see if ubuntu saw the device but it didn't. Maybe there's some things needed that I didn't do. The thing I don't understand the most is why do windows see it as an unknown device only with the battery out while if I connect the G3 with the battery on, it doesn't show anything on device manager..

Hi there.
Please check these 2 threads out and see if any of it will help you. The one for the G2 can also be used for G3.
Here are the links:
http://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091 With this technique you would have to find the software online somewhere but this method does revive dead G3 with these symptoms.

If I helped somehow, hit the THANKS button.
Good luck!

The thing is I can only get the device to be recognized as an Unknown Device in Device Manager and only with its battery out. If I keep 'volume up' pressed nothing happens, it's only shown after I simply connect the USB cable and it pops up after 10 seconds or so. It's very consistent in the way it behaves..

A small update, sometimes when I pull and put the battery again, I connect the phone to a pc while holding down vol- and the pc makes the connected usb sound while the phone led is blinking red for a couple of minutes, then it stops. That's about all there is concerning the phone giving signs of life..

Soft Bricked LG G Pad II 8.0 (LGV498) Wifi only

So I soft bricked my LG G Pad II 8.0 Tablet... Not the worst thing in the world, except that 1.) There seems to be not much at all on the internet as far as stock ROMs or how to guides on fixing my particular tablet. 2.) My computer does not seem to be recognizing my tablet when trying to use ADB, despite having installed all the drivers etc.
My device is stuck in a BootLoop, it will allow me to try a Hard Reset, which is unsuccessful. But it will not go into recovery mode OR Download mode no matter what sequence of the buttons I push and i've scoured the internet trying different button sequences.
My Tablet will charge when plugged into USB, my comp will also go *ding* when i press the power button with the tablet plugged in as if it is reconginzing it and everything. Also Device Manager seems to have it listed with no Exclamation Point or any sign of trouble... Just when I go to use ADB and i search for the device it says *error no device found*
The Tablet just sits there with the LG Logo screen pissing me off more and more as my attempts fail.
I will say USB debugging was not enabled beforehand *cough cough* my mistake
Will reflashing it work by using the MicroSD card method? If that is the only way i will have to just buy one i guess. It did not come with it and it is a Wifi only tablet, no carrier attached.
And if I try the MicroSD method, will it still work without being able to put the tablet into recovery mode?
I believe I have the correct .IMG file for my stock ROM... I just can't seem to get anywhere with flashing it to the device at this point.......
Please Help!

*UPDATE* So I happened to stumble upon a random piece of information that proved REALLY useful in this situation. Someone put in a forum that Lollipop ONLY is detected when plugged into USB 2.0 ports NOT USB 3.0 ports like I was using. So I did this and was able to make my tablet enter into Download Mode FINALLY.... Anyone have any good methods on how to Flash Stock ROM using ADB and a connected soft bricked tablet?
I have already tried a couple methods that I have found and they were unsuccessful. One was using ODIN software and the other was using LG Flash Tool, unfortunately neither worked....

LG G3 F400K cannot go into USB MODE

Good day.
I was trying to restore my phone back to its original LG OS. Getting rid of the unsuccessful root. But I can't go to USB mode whenever I connect it to the USB. I can see the download mode if I press the vol up. But after that, the screen just turns black. I'm sure the PC is not the problem since my PC has a voice command whenever a device was putted or pulled out.
I am following this guide and I'm doing great with it. But my phone won't get recognize by my laptop (HP/Windows 8.0)

I hope you can all help me so that I can use my phone again. Thank you

Oneplus 3 just died out of no where

So i was using my phone and decided to restart it after updating my adaway files but my phone never turned back on. The two press the power button screens did not show up either. I tried to uses the MSMdownload tool since i thought my phone was somehow bricked but that didnt work either, it just kept restarting the download process after everything was completed. my computer makes a sound when its connected and it connects correctly as a quallcomm 9008 device but even after all this nothing is working. has anyone experienced something like this or does anyone have any advice?

did you try to long press both power button and vol up ...you should feel a vibration...
maybe it's not turned of maybe it's error causing the screen to be off... also is there any heat?

Which method of the unbrick tool did you use? First or second? If the first, then maybe you should give the second also a try.

I've tried everything and I used th me second method yet nothing happened. I can see my phone get recognized by the computer and get listed on the MSN device list yet nothing happens after it finishes the process. After the green line shows up telling me that it's completed everything the process restarts writhing a few minutes unless I unplug it. No vibration no nothing the phone just died on me after I restarted it .

Try doing MSM on a different PC with all drivers installed , hope it helps

Try to repeat flashing again, there is no other way. Use method 2only. Extract tool again and try flash.

When I was used Xperia Z1, I bricked my phone with a soft brick. So I installed driver in my PC and flash Kernel though FASTBOOT(ADB) either it's not show Device in my PC (I show just "Unknown Device").
After that my phone can connect to my PC again (Now It shown C9303 or something that meant it know it's a phone).
So I can flash by Flashtools again. Soft brick is not scary as Hard brick, you'll find some way to bring it back easily.
Hope this help!
PS. Bricked Phone is WEAK in Battery, always connect it with charger.
