Hi,
After a serious software problems (crashed with 4.0.3 OTA update) i managed install a ROM, but my screentouch doesnt respond to my touch. The screen and all buttons function very well but i cant put the pin because touchscreen doenst work.
Could it be Software or is definitely Hardware?
Could be software. Have you tried flashing a new ROM (and appropriately wiping beforehand)?
Have you tried to access to the recovery ? Some recoveries use the touchscreen as the TWRP for example

I can acess to recovery sometimes
When it fails push it in PC via fastboot.
Now i cant enter in recovery and cant connect via usb to flash another recovery
I'm screwed!
I cant get into recovery, when i pressed appears a android toy whith a warning sine.
I cant connect to PC, when in bootloader and connect to PC, in bottom appears "fastboot fails invalid command".
I´ve installed a stock rom 2.3.6 and the touch screen doesn´t work to iniciate the phone. Try to install franco kernell but it´s the same situation.
When i can connect the phone to PC i´ve try´de 3 different custom roms and none works.
Going to warranty.
Looks like your touchscreen may have just given up. Everything else is normal, you probably don't have fastboot/adb setup properly and that warning sign is the stock recovery. I'd sort out fastboot and lock the bootloader before sending it in. Also, if you don't have a backup of your sdcard you can mount it through a custom recovery (use "fastboot boot recovery.img").

I´ve format SD card and have nothing inside.
"I'd sort out fastboot and lock the bootloader before sending it in"
How can i do that?
Remember that i cant access to recovery or turn on by computer.
Read the rooting guide or check out NexusSHacks.com, all the info you'll need.
How are you "pushing" recoverys via fastboot if you don't have fast boot set up properly?
Anyways. Speaking of fastboot. Get the official fastboot images for your phone and flash them all. If you still have issues with the screen its a hardware problem.
You should make a full backup and then flash the official factory images (ICS 4.0.4), made for your hardware version, through fastboot. You can find the exact version beneath your battery on a sticker.
If the problem persists after this, it's most likely a HW problem.
If the mobile is not recognized in bootloader / fastboot mode, then connect it to a Linux PC, and then post here the output of the following commands (as root):
Code:
tail /var/log/messages

After trying to unlock my phone and flashing stock rom through CWM I accidently downloaded the rom for the at&t model. I own the sprint model. After flashing the incorrect boot img and radio img the fastboot just spat out errors so closed the CMD and booted up the phone. No longer does the USB work i have tried several computers none detecting it in either bootloader or within the android os. The android os doesnt even ask to mount it it just charges. Any help would really be aprreciated!

OK firstly never close CMD when it is doing stuff that can cause damage to your PC, device etc. It can cause serious damage
I haven't tried this myself but you could try using a different USB connector. If that still doesn't recognise your device then it is a hardware problem or you have messed up you device.
If it works then download the sprint version and flash.
Hope this helped,

Wait what ?
So you wanted to unlock to flash stock ROM with cwm recovery but you used fastboot to flash boot radio etc .img's ?

CWM Is no longer there after i restored it I was able to flash a stock ICS through normal recovery but the usb is still not working.
From a powered off state, if you hold VOL down and then press POWER, can you access download mode?
If yes, and you connect it to your computer (I'm going to assume you are using a windows computer), can you hear the device connected sound? It should get detected.
Hi,
I tried to install a ROM but it got stuck on the white screen with the HTC logo. I tried to do factory reset but it gets stuck again. I don't have clockwork recovery, and I rooted my phone using adb and ace recovery, which is not on my phone. I only temporarily used it to flash my rom, stupid I know. :-/ When I connect my phone to the PC it is not being recognized. I tried putting the PD98IMG.zip file on my sd card but it just says that it the image is incorrect. Is there anything I can do? Is this fixable?

I just went through some similar stuff. What type of computer are you using? PC/Mac? Are you using the original cable? What troubleshooting steps for connectivity have you done? Different cable? USB port?
Can you access the bootloader screen when you pull the battery and reboot while holding the volume button down and holding the power button? By accident, I found that the phone and PC will communicate with each other when "Fastboot" is selected on the bootloader screen (you should hear a connection chime and it should change to "Fastboot USB") except I could only get fastboot commands to work. The good news is that should be enough to flash a boot or whatever else you need to get back in business.

Hi, Thanks for the reply.I am using windows 7. I downloaded the drivers for HTC, and I am using a data cable and the USB port in the back of my computer, nearest the mother board. I do see "Fastboot USB" on the phone but when i type in the command prompt "adb devices" I get nothing.

That's great you're getting the fastboot usb message! As long as you're not using a hub or some other usb extender, any functioning usb port on the pc will do. Again, I learned this by accident (ie the hard way) and found that in this mode, only fastboot commands will work, not adb. (on a side note, and others should correct me here, adb and fastboot work together when the phone is rebooted normally or in recovery but not in the bootloader screen)
Great test for connection: fastboot devices (if you get anything else except a serial # with fastboot after it, then close the cmd window, unplug, and pull battery/reboot to bootloader), fastboot reboot-bootloader. Once it reboots back into the bootloader screen, make sure you press the power button while fastboot is selected and you should again hear the chime and see fastboot usb come up. This is your phone saying it's ready to accept your fastboot commands.
Do let us know how it works.

As far as I know, fastboot only works when your phone is in fastboot mode. ADB works in recovery or system.

Flash a rooted stock ROM from recovery. Whether you have root is in your system partition. Whether your bootloader is unlocked is in your bootloader. Whether you have a custom recovery is in your recovery partition. Three separate things.

I'm guessing that you're trying to flash a PD98IMG.zip or a RUU. You need an actual stock rooted ROM, probably from here on the forum. Or just flash Android Revolution HD, an optimized rooted stock ROM, also from here on the forum in the development section. For more specific steps read the Ace Think Tank linked in my signature.

Dear friends,
I have this problem: I got a brand new TCL S720 and the Google Play did not work, being a known rom issue. So, before doing anything, I've managed to make a backup of it's original rom with MTK Droid tools whichI supose it did it well. Then I've tried to install a CWM recovery to try a custom rom for it. The CWM recovery seemed to install succesfully but I didn't manage to install the new rom. If I remember well, it stucked on boot logo. Then tried to revert at it's original stock recovery, managed to have the phone back as it was in initial state, but doing more tries, It remained stucked on boot logo. The problem is that my computer doesn't recognise it anymore, when I connect it to USB it tries to install MTP usb driver but even before the driver was installed well, now it refuse to install, like the driver is not good or the proper driver doesn't exist. So the only thing I can do is to boot on stock recovery but even I tried to copy the original rom update.zip on external SD and to flash the phone using install update from sd card in recovery mode, It doesn't find the external sd card. So I'm stuck here, the computer doesn't detect the phone to try flashing it with SP flash tool or MTK Droid tool, and I also can't flash it from sd card. Have you any idea how to make it work again?
Thanks in advance.
Hi there,
Im still kinda a noob with android...
but i managed to unlock my htc sensation trough the steps @HTC,
changed the recovery, tried to flash a rom.
it failed due to my phone not being S-off. so i flashed it back :/
no problem there i thought just a rooted htc.
downloaded an app to remove bloat. and all seemed fine...
I was playing Clash of Clans, and it gave a message that the Google play services stopped and the phone rebooted.
when booted the lock screen was frozen, i pulled out the battery to find out my phone is unresponsive..
When i connect to windows 8, it cant recognize my phone at all
When i connect it to a charger i dont see the charging light.
and the worse thing is.. i cant get into the recovery.
any idea's what i can try?
i checked out the [unbrick] tread but i cant seem to figure out which "Package" i need and the links on the bottom of the page dont work when i click them
Thanks in advance

At first you have not to be S-OFF in order to flash a rom.
Your rom will get installed just fine.You just need to flash the kernel of your rom manually through fastboot using the command fastboot flash boot boot.img.
What exactly do you mean by telling "so i flashed it back"?
Did you relocked your bootloader with fastboot oem lock and you flashed an RUU?
You said you are just rooted.If my theory was right you probably unlocked your bootloader again by flashing the unlock.bin and a cwm recovery and then you had to use a (Superuser , SuperSU zip).
The first time you unlocked your device was you using the same computer with windows 8?
If yes this is a problem.Check your device manager for unrecognised devices.Can you see the device?
Check this out.You can also check this.
(You can try with win7 or a linux destribution instead.)
Are you still able to boot into bootloader (hboot) using (Power)+(Vol-) Buttons?
If you have enabled usb-debugging and a working adb shell despite you are in a bootloop you can try:
Code:
adb shell
su ------>(If you don't see # instead of $)
reboot oem-78 -------> To get in RUU mode
or
reboot bootloader -------->(To reboot into hboot)
* reboot recovery could bring you to recovery *
If you can get into hboot or RUU mode give the command fastboot getvar all and copy-paste what it prints.
I know it was possible to flash with S-on,
thats what i tried and it failed (manually flashed the boot.img resulted in a bootloop)
so i flashed back to the "stock" rom.
resulting in a "normal" rooted device
since i've replaced my recovery and got root access
it never has been oem locked again.(still isnt)
i cant get into my bootloader/ruu mode. nor start up.
when i plug it into my computer (windows 8) it makes the sound as it does when you connect a device.
but in device manager it shows nothing, not even a yellow ! as it normally would if it can recognize a device.

As you have not access to bootloader but your device is still seems to get connected i think you can only try HTC Unbricking Project.If the brickdetect.sh is not working you can try a different linux destribution.

Hello,
I just broke my nexus 5 screen but the device is still working. I'd like to retrieve some files from my phone before buying a new one, like pictures or SMS for example.
Here is what I can do :
- Boot in fastboot mode
- Flash a custom recovery (ex : TWRP)
Here is what is not working :
- Device is not recognized in Windows file folder, then I suppose that MTP is not enabled
- no developer mode enabled
- no USB debugging mode enabled
- Then ADB is not working
By the way, the device is not unlocked and not rooted.
I tried to flash and boot into TWRP mode but I don't know how to "drive" it from my computer as the device screen is not working.
Could somebody help me please ?

You can`t, the bootloader is locked so you can`t flash custom stuff like a recovery. And even then you couldn`t know what buttons you`ld press if you can`t see what you`re doing.

Unlocking the device wipes the device, so this kills the whole purpouse of your question. Might as well do nothing and get the phone repaired or buy a another one.

if bl is not unlocked... you won't be able to flash a custom recovery to use ADB to pull files.. so.. you're done here.
I maybe found a solution but I need a specific apk.
I may use the sideload mode to push and install a ROM or an apk. The best would be to push/install an apk from sideload mode, and this apk would automatically launch itself at device startup and will activate USB debugging mode which will allow me to fully use adb.
What do you think about that ? Would you know an apk which would do that ?
Or secondary option, push a specific ROM with USB debugging enabled by default. But I'm afraid that it could erase all my data.

Well I guess you're a bit stuck unfortunately.
Can you try ubuntu.
download a live cd version and boot into ubuntu or maybe a smaller version of linux (i know ubuntu works)
once booted into ubuntu plug in the phone.
usually linux can read the file system even when windows can't
You can't flash anything unsigned with stock recovery.

Yes it does. And it's responding in fastboot and sideload mode. So the phone is working, it's just the screen which ia dead.
The only way is to install a custom recovery. There is no other way. However as you said, unlocking the bootloader will erase everything.

sorry that did not work.
when connected to ubuntu and you type "fastboot devices" do you get a response?
If so ubuntu can not browse file system in fastboot mode, you need to reboot back to the OS.
type fastboot reboot and when the phone reboots try to browse the file system.
