[Q] HTC M9 Possible Brick?

Hi
I recently received my shiny new M9 and like I have with many HTC phones prior to it unlocked the bootloader installed TWRP (latest beta version) and installed my rom of choice (LeeDroid). For about 10 days now the phone has been great working well on the new rom and all was well with the world.......
Last night the phone rebooted on me and boot looped about or 6 times before finally booting correctly and then behaving normally. Today however the phone is constantly boot looping and failing to boot. I can access the bootloader menu via vol up and down and power button but if i select recovery or download mode the phone simply boot loops over and over. RUU mode also does this.
Once in a blue moon if the phone is left looping over and over it will actually boot into the rom and work ok but as soon as the phone is reset or runs out of juice its all aboard the boot loop express.
regards
Brian
Fastboot commands work however adb commands do not. I have fixed boot loops previously but on this occasion a solution appears to be evading me.

Sounds like a tricky one, you cant get to download mode to flash a new recovery and cant boot recovery. So if you can do fastboot commands do you mean at the bootloader? If so you are limited without s-off in what commands you can do from bootloader menu. I would be looking for an RUU based on your cid to get you back to stock at this point. You may have to wait. You say adb commands dont work.. have you enabled developer options and installer drivers on your pc?

Dev options have indeed been enabled and all drivers installed I can use adb on my partners phone with no issues. Fastboot commands as you say only work at the bootloader screen,
Sadly I cant even flash a RUU the moment i try it simply reboots the phone back into the bootloop :crying:

Try updating to very latest fastboot, I had to update my sdk a while back as fastboot wasnt working properly with newer phones. Worth a try

Still fubar
Once in a blue moon the phone boots into the rom fine and you can use the phone its very weird I literally am all out of ideas now.

Think im gonna bite the bullet and send it back to Vodaphone and pay to get it fixed. I cannot enter download or recovery mode by any method that I have been advised or have read about thanks to those who tried to help it was appreciated.

Well you can try this in the bootloader. Open up a cmd window with fastboot in the directory and type fastboot erase cache
then type fastboot reboot

Download an ruu for your device. Rename the file to 0PJAIMG.zip
Place it on a sdcard with lower than 32gb and flash it. Need to flash it twice. Directly after each other. All done in download mode

I can'r get into download mode sadly and I have tried many many methods from threads about how to do so. Recovery mode and Downlode mode are just not working hence I think It's going to have to be repaired :crying:

That's not possible, do u press power and up volume for 10 secs so it restarts and then immediately volume down?

I do indeed and the phone then either shows the battery indicator for about 5 or 6 seconds then reboots or simply reboots. If i selected recovery mode in bootloader the phone just reboots as well.

How did you get into boot loader?
You could choose download there, or reboot into ruu mode

I can get into bootloader by holding power + volume up+down but If I select either recovery or download mode the phone simply reboots normally and commences boot looping again. If RUU mode is selected the phone DOES reboot into RUU mode but if you try and flash the RUU the phone simply reboots and boot loops.

Try placing the zip I mentioned above on SD card.

Still unable to enter download mode via any means so I think it's going to have to go in the freezer till it wont boot and I can send it back
Things I still CANNOT do
Enter Recovery (Phone simply reboots and commences boot loop)
Enter Download Mode (Phone simply reboots and commences boot loop)
If I try and charge the phone with it turned off as soon as it gets power it boots up and boot loops Once in every few hundred boot loops the phone will make it into the rom and will work ok untill eventually it decides to bootloop again after a few hours.

LG G4 won't stay in download mode. Bricked?

Hi!
Today, while using my G4 it shut down and did not not want to boot up anymore.
At home, when connecting it in download mode, I flashed a stock KDZ (been on Genysis rom before). It went smooth, but the screen kept showing the Life's good screen (it didn't even enter the animated part, which makes sound). Then I wanted to reflash it again, but it does not stay in download mode.
I can't force shut it down, I can only remove the battery, but once I place it back it powers on (doesn't stay off).
I can quickly put in the cable and volume down to enter download mode for a brief second, however LGUP, doesn't recognize it and after 2 - 3 second it goes on to the main LG screen.
Is there anything I can do?
Thank you

Same problem! Fastboot does not recognise it either when I do fastboot devices. My G4 is also the Taiwan version so no chance of unlocking bootloader. It can't even do a hard reset. Please help!

Open "device manager" on your computer (and keep it open) and see if the driver is the correct one and if it doesn't change during the flash or while you need it. Specially on Windows 10.

Please try a live Linux instead. On windows you will always have problems with drivers.

To clarify, are you saying that selecting any of the options except 'Power Down' cause you to reboot back into download mode?

boot to bootloader white screen only if i slect boot to download it reboots to white bootloader screen everytime

Well, you've already tried RUU via sdcard. From your choice of ROM, it looks like you're using a Verizon-branded device - is that correct?
It may be worth connecting your phone to a PC and attempting to repair your phone using Verizon's Software Upgrade Assistant (start with HTC's Sync Manager) to repair the phone. Verizon provides instructions on it's website.
Assuming this works - and that's a bit of a long shot, given your symptoms - you'll almost certainly be returned to a S-ON state. If your phone is currently non-functional, that seems worthwhile but you'll have to make that decision.

HTC's Sync Manager come up auto when phone gets connected but cant get phone to connect to it good idea tho-i will leave it hooked awhile mabe it will --------

I have a very similar problem. My phone is Unlocked and S-OFF. I tried to install TWRP after I had gone back to a standard rom. When I went to recovery it boot looped. To get back to bootloader I have to hold volume up and down if I try to go to download mode it boot loops if I power down with whilst connected to the computer it boot loops. I have tried to install a standard rom but get partition errors "remote: partition table doesn't exist". Does anyone have any Ideas?

Unable to boot into system or recovery after locking bootloader

So after locking the bootloader in an attempt to get Android Pay to work, my OP3 tried to reboot itself but the only thing that happens is the Android logo flashes for half a second and the phone vibrates as it usually does when I boot it, then the screen goes dark for a second, and it repeats continuously like this. I'm completely unable to use my phone because of this.
I've tried entering fastboot mode which seems to work but when I try to enter recovery mode or start the phone, the same thing happens. I can only power off or restart the bootloader from this screen.
I'm assuming the bootloader is locked because the device state is displayed as locked in red while I'm in fastboot mode (or bootloader mode?).

Turns out I just needed to unlock the bootloader again. That seems to have done the trick for this issue.

OK that's fine, mine suffered the same things but the bootloader was still unlocked.

N975F/DS can't Unlock Bootloader, but OEM Option ON

Hello everyone,
Sorry for disturbing you but I'm desperate, I tried everything and I can't find a way to unlock my bootloader, Here are the steps I've done so far ... First I've activated the OEM Unlock option in the dev mode, then I've turned off my phone and booted into recovery by pressing bixby boutton + Volume up, Then I choose Reboot into bootloader and so far from there I got only a screen saying to hold Bixby + Volume down for more than 7 sec to reboot the device and also got a bar code there ... I don't got the function to unlock the bootloader as everyone else ...
Also I've bought my phone yesterday here in saudi arabia, and I got the latest firmware version and that it N975FXXU1BSL7/N975FOXM1BSL9
Model N975F/DS

If you must unlock your boot loader, plug your usb into a pc, turn off the phone, hold volume up and volume down together, and plug the usb cable in.
Then you will find the unlock option.
