[Q] Black Screen

On my HTC One V I unlock bootloader and rooted it successfully. It was working fine, but about 1-2 weeks later, when I was chatting with my friends on Messenger, it was starting to lag like hell until i couldn't do antyhing. I tried to turn it off and on with the power button. When I turned it on, firstly the logo "Quietly Brilliant" appeared and then...there was just a black screen. The phone was still turned on, but just with a black screen.. a slightly lighter black screen. I tried to turn it on and of. I can go to fast boot mode with Volume down+power button. I tried factory reset, but there was still the black screen. I send it to the manufacture, but they said, that the hardware is destroyed, because I've changed it. I think they mean I changed it with root and unlocking the bootloader...but I think that's not true? I don't think root or unlocking bootloader can change hardware. Yet I tried to unroot and relock the bootloader, but I can't do It if I can't connect my phone to my pc anymore. So my questions are:
1)How could I change the hardware?
2)How can I connect my phone to pc?
3)Is there a way to save my phone?
4)How does the manufacture know, that my phone is rooted when it can't be turned on, or connected to pc
5)Do they just lie about the hardware, so I must pay for it?

first of all, are you gsm or cdma? (do you have a sim?) If you can access bootloader, then you can fix your phone (99,9% of times). all you need to do is flash another rom with the correct kernel

Yes, I have s sim..so I have gsm i think? Right now, the manufacture is sending me back my phone. What is the bootloader exactly? Do you mean the combination of the keys volume down+power button?
If yes and I can acces to bootloader, how can I flash the rom with the correct kernel? Does it mean, my phone will be back to normal like it was at the start?
If I can't acces to bootloader, is there still a way to repair my phone?
btw I can't connect my phone to my pc...at least It didn't worked.

Don't worry, when you get back your phone tell me. If you can access your bootloader we will get your phone back to normal :thumbup:

first thing, when you get your phone back access the bootloader, hit fastboot and connect the phone to the pc (then after some seconds try vol up or down), it should say fastboot usb. tell me if it does (write it here)

When It's turned off, I hold the volume down button and power button together for 10 seconds. Then I let it go, but there's no bootloader mode. Before I sended it to the manufacture, I somehow did it, but I don't remember how.

Hey sorry I have to go to school now.. I'll write a little guide as soon as I come back, be patient. In order you have to unlock and root (if you haven't done it already), flash a recovery (I suggest twrp recovery, you can find it in android development or original android development-This also only if you don't have that already), factory reset from recovery, mount usb storage, copy rom to your phone, unmount, flash the rom, reboot into bootloader and flash the correct kernel found in the rom thread. This should work. I'll give you a hit when I get back tough.

Its bootloader is unlocked and it's rooted. Now for the recovery i found this:
http://www.teamw.in/project/twrp2/119
They say I should download the newest recovery img, access bootloader, select fastboot, plug the device into computer and run the command:
fastboot flash recovery recoveryfilename.img into command prompt right?

Yes its right. Then you boot into recovery, and mount usb storage and with the pc copy a rom into the sd card, then unmount, from the recovery go to wipe - > factory reset, once it's done go to install and select the zip of the rom. When it's done, go back to the home page of recovery, and from there press reboot bootloader. Now do fastboot, and from the pc, put kernel in fastboot folder (the same place where you put your recovery to flash it), open cmd and type fastboot flash boot nameofkernel.img, wait for it to complete, reboot and enjoy!

When I type "fastboot flash recovery recoveryfilename.img" into the command prompt..it tells me:'fastboot' is not recognized as an internal or external command, operable program or batch file

Have you downloaded the fastboot folder? And have you located it in cmd?

I have a folder named Android an there's: adb.exe, AdbWinApi.dll, fastboot.exe, Unlock_code.bin
Do you mean this?

Yes, now create a folder on the desktop called fastboot and copy those files in that folder. Then in cmd type cd desktop (enter) cd fastboot (enter), put the recovery in that folder, connect the phone on fastboot usb and type the recovery command

If you are able to boot into fastboot, search the latest TWRP and flash it via adb. Connect your device while in fastboot mode and see if it recognize it.
If it does put the recovery file you have downloaded on your desktop and open a command window, press shift and right click at the same time and click on Open command window here.
Type adb devices, if you see a serial number go on and type adb reboot bootloader, then type fastboot flash recovery [ the name of the recovery file you have just downloaded ]
You can do this just by powering on your phone, no need to be already in fastboot mode, just follow the commands.
Press shift and right click : open command window here : adb devices : adb reboot bootloader : fastboot flash recovery [ the name of the recovery file you have just downloaded, do not forget the .img extension ]
fastboot reboot
Once you have a working TWRP you can flash your corresponding backup and go back to stock. The backup will be flashed from TWRP, search for instructions.

http://teamw.in/project/twrp2 and click on the upper right Get TWRP for your device.
Choose your device recovery and download the adb version. That is the .img
Once you have downloaded TWRP put it on your desktop.
Connect your device with your laptop/pc with the unknown sources checked also the usb debugging checked.
Move your mouse over a free space on your desktop, click once just to be sure there is no app or file clicked.
Then press shift and keep it pressed while you right click your mouse.
Press open command window here
in that command window type : adb devices
if you see a serial number type : adb reboot bootloader
then type : fastboot flash recovery openrecovery-twrp-2.8.1.0-m8.img
fastboot reboot
openrecovery-twrp-2.8.1.0-m8 : This is an example, you will write the name of your recovery but it should be pretty much the same.
Good luck.

Are you familiar with
adb/fastboot commands?

You say "pushing a ROM" with what?
You don't push a ROM with TWRP you just flash it.
Or are you talking about pushing the ROM with fastboot?
If you have TWRP than download a stock backup and flash it.
Take a long look at my profile man and if you look just right you will see I've done and asked some stupid things in my travels here on XDA.I can tell you I remember every phone and ridiculous thing I've done to each of them,I still feel crunchy when I think of the mistakes.
We really need more info about the full process.please I'm not trying to offend you and I'm trying to help

If you can't remember what you did, or at least even try to list in detail the steps you did as best you can remember; it makes it very hard for anyone to help.
Saying you followed some tutorials on an entire website (3 websites actually) doesn't tell us jack, and isn't any better than telling us nothing.
Its not even clear the current condition of the phone. Your OP says TWRP doesn't work, then a later post says you are trying things with TWRP, so presumably you have TWRP. But since you never stated that, we can only guess.
What happens when you try to adb push or sideload? What error messages, does it make the phone reboot, stuck on boot screen, etc?
TWRP working? Bootloader is unlocked? If yes to both of those, you should be able to just adb push a ROM, or put one on removable SD with a card reader attached to your computer. Than flash the ROM in TWRP.

I recently decided to root and install a custom rom on my old stock sprint HTC one m8. I unlocked the boot loader via HTC Dev website. I then flashed the TWRP recovery. Since doing the latter step, it's been booting into fast boot all the time! Did you ever figure out what was wrong with your phone?

You only flashed TWRP onto the phone? Or did you root also?
Not nearly enough info to provide the proper help.
Please do fastboot getvar all, and post the results (delete IMEI and serial number before posting).
What version TWRP?
What version SuperSU did you flash (if you got that far)?

ROOT Elephone S7 4gb on Windows 10x64 at last!

For those that, like me, could not get driver recognition on the latest Win 10 x64 no matter what you tried. And ,yes, using every tutorial I could find on this and two "other Forums". Odin failed to see my device (still can't) Cydia impactor allows rebooting into fastboot and D/L but doesn't connect in either alt. mode. Yes, drivers all removed and replaced in varying states (usbdeview, etc.).
But ADB/Fastboot works!
Make sure you have your adb/fastboot drivers installed universally (Check this Fabulous Forum)
Download device-specific TWRP - I used this one for the 4gb version - https://www.dropbox.com/s/b7u3k1mgpppxlyx/recovery.img?dl=0
L.Shift-R. click in the folder you downloaded to (Open Command Window Here) - "adb devices" (to make sure device registers) then - "adb reboot bootloader" gets you into fastboot. - "fastoot boot {your-recovery-name}.img"
I got a fully functional TOUCH CAPABLE TWRP. Which I proceeded to load this - https://www.dropbox.com/s/j1owqv7mjkdpo75/UPDATE-SuperSU-v2.46.zip?dl=0 - and, VOILA! ROOT!!

I had similar issues with my laptop and drivers. Used a friend laptop in the end to "see" the phone and install twrp.

When I try to boot the recovery.img with fastboot it says that my OEM is locked. I check OEM unlock in developer options, then I do: adb reboot bootloader, then fastboot oem unlock. A warning appears saying to press VOLUME UP button to continue, voiding the warranty or VOLUME DOWN to go back. I try to press VOLUME UP and nothing happens... how did you do it?

Hi there, I have the same issue. No success

I found a way, instead of volume up, use the home button this worked for me.. however after I unlocked the OEM and flashed TWRP the phone didn't want to boot anymore. It was stuck on Elephone logo with warning: "Orange State: The phone has been unlocked and can't be trusted. Your device will boot in 5s", however it didn't boot and stayed like that for almost an hour. Had to flash back the stock firmware to boot. Tried 1 more time the procedure to root but again the same. Maybe I do something wrong?

stock fw flash back
Hi, please can you help me with how you flashed back the stock firmware?
I get an error message with twrp : invalid zip file format.
Thank you in advance!

I read somewhere the is a zip inside the update.zip & is that one that is flash able with twrp.
Have a look

During the main time I managed to flash the 0218 stock rom.
I still got the orange message but the phone finally boot. Then I just called the twrp recovery img via atb. I did nothing only touch the reboot in the twrp screen and since then "Orange status...." again.
May be the twrp recovery img is not the right one...

Bad command "fastoot boot {your-recovery-name}.img"
after OEM alow (informacion phone/compilacion number touch fast 9 times/access/alow oem)
fastboot oem unlock
"fastboot boot {your-recovery-name}.img" for me is fastboot boot recovery.img and all OK
bat still not working (phone not thrust unlocked bootloader cleaning data in 5..4..3..2..1.. and rebot)

How to wipe android partitons while NO access to Fastboot? PLZ help

Hi,
I have a unique problem. I cant go into fastboot. Yes, fastboot on my OPT is not a opltion.
I cant instal TWRP. I can't wipe the OS to flash a new one.
My question is this:
Is there a way to wipe the partitions on a android phone via windows or something?
This problem is created by me. Somehow I flash OOS over CM (??)
So when my phone boots (bootloader is unlocked) I will see 2 boot sequences wich prevents me from accesing the fastboot menu.
The solution I see is this: Enter TWRP --> Wipe all but USB-OTG ...
Anyway, I hope there is a android Einstein here because I'm at a loss..
Feel free to ask any questions and pls help me!

If you are getting two boot screens, please confirm if this is what you see in your first boot screen:
some text which goes like "Your device cannot be trusted etc etc. fastboot oem lock something something"
If yes, press the volume buttons at this screen, which will take you to an "Options menu"
This will have options to power off, restart, recovery, fastboot, back to previous page.
use volume down buttons to move selection to fastboot and press power button to select fastboot.
This will take you to bootloader.
Alternatively:
Is the device getting identified by your computer when connected?
If yes, and if you have adb tools installed, try this command, after connecting to computer and selecting usb configuration as transfer files
adb devices
The result of this should show your device
then type:
adb reboot bootloader
This should take you to your bootloader screen.

Thank you for your replay.
I have done all of this and i do understand how this works.
I have adb drivers installed, my computer does reconizes my phone and everything works even the reboot to bootloader via CMD. (adb devices, it shows, etc)
When my phone then tries to access the bootloader, it will show those messeges " this devices cant be trusted etc etc." afther 5 seconds again I see the the android logo (with a few lines of static on the bottom) (( that clearly is not right )) but it will show me again the same message " this devices cant be trusted etc etc" ... then it will just show me the battery icon and power precentage (this if I choose to boot to bootloader) or else it starts normally..
Clearly the flashing of CM failed. And with a sideload to install OxygenOS I can use it.. But it does prevents me from accessing the fastboot mode..
So Is there an alternative way to install TWRP without using the fastboot mode? Or is there an other way i can try to wipe the partitions inc. the os?
From there I know what to do.

When the display shows the battery % check if fastboot devices shows your device?
If not I'm sorry, I would not be of any more help to you my friend.
Hope someone more knowledgeable comes along and clears your problem....

Thank you for your replay.
I have done all of this and i do understand how this works.
I have adb drivers installed, my computer does reconizes my phone and everything works even the reboot to bootloader via CMD. (adb devices, it shows, etc)
When my phone then tries to access the bootloader, it will show those messeges " this devices cant be trusted etc etc." afther 5 seconds again I see the the android logo (with a few lines of static on the bottom) (( that clearly is not right )) but it will show me again the same message " this devices cant be trusted etc etc" ... then it will just show me the battery icon and power precentage (this if I choose to boot to bootloader) or else it starts normally..
Clearly the flashing of CM failed. And with a sideload to install OxygenOS I can use it.. But it does prevents me from accessing the fastboot mode..
So Is there an alternative way to install TWRP without using the fastboot mode? Or is there an other way i can try to wipe the partitions inc. the os?
From there I know what to do.

If nothing works, try method 2 from the Hard Brick guide from Naman Bhalla.

Is there any way to turn s-off from bootload mode? Because there is no way to turn this on so i can turn off it from programmer options

I cant post links as a new user so please copy it yourself.

You need to flash recovery from download not bootloader and you need an unlocked bootloader.
Also you can't flash ruu from recovery, you need to put the file named as 0PJAIMG.zip in the root of your fat32 formatted sdcard and boot in download.
If you need more help you need to boot in download and run "fastboot getvar all" then post the result here(remove imei, sn).

No, you need to enable oem unlocking in settings to be able to unlock it.
Your only option is to flash it by ruu.
This is the ruu for your phone: https://androidfilehost.com/?fid=457095661767124956
Rename it to 0PJA100.zip and put in root of your fat32 formatted sdcard then boot in download and follow onscreen instructions.

Well did as you said and problem is the same - when I start it from download mode it just keeps rebooting phone with HTC logo.
Looks like this phone is really dead thanks for your support

The process completed successfully, without any errors? If so, the nand is most probably dead.
Also you can try the fastboot method to flash, maybe you have some luck...
You need htc_fastboot.exe for this
"fastboot oem rebootRUU"
"fastboot flash zip RUU.zip" - do the command again when/if it asks.
"fastboot reboot" - when the process finish.
