HTC One M9 Hard Bricked + corrput download mode - One (M9) Q&A, Help & Troubleshooting

Hey there!
I had problems with my HTC before but I managed to fix it by unlocking bootloader and reflashing the stock recovery.
Then after a few weeks my HTC suddenly rebooted itself and got stuck in a bootloop. It then said Phone Storage is encrypted and decryption failed. So i went to recovery mode and did a factory reset which did not work.
Right now bootloader says this: "STATUS:MODIFIED / RELOCKED / S-ON / SECURITY WARNING"
When I try booting to download mode it says: "FAILED TO BOOT TO DOWNLOAD MODE" with the security warning
When I boot to recovery mode it says: "MOUNT /CACHE FAIL" , "CAN'T FIND DEVICE NODE FOR MOUNT POINT /CACHE", but I can navigate normal through its options.
When I try applying an update from SD card oder sideload it always fails and puts out more "FAILED TO MOUNT /CACHE /DEVLOG..." warnings.
When I try to apply the RUU.exe it says my phone isn't charged more than 30%.
fastboot getvar all in bootloader mode wont say anything except my SN.
Wipe data/factory reset or wiping cache will fail and output more "CAN'T MOUNT ..." errors
I can't install a new recovery like TWRP since my bootloader is relocked and download mode is inaccessable.
Also, if my phone is connected to any power source and I power it down it will show the charge animation for a second and hop right back into bootloader.
Anything else I could try?
Thanks (can't put in any images because i just registered..)

I have same porblems but i have the phone unlocked with s-off. Can you help me to fix it? thanks.

I hate to say it, but you might be having some hardware issues with the motherboard. I'm not sure what solution (if any) is available: without download mode or recovery (and a locked bootloader), you may well be out of luck. I'm sorry.

[Solve] Stuck in Jelly Bean OTA update

Hi there !
I have a little problem with the JellyBean update on my rooted One X. I didn't know that I must go back to a stock recovery before doing the update so i discovered it when it refuse to do the update.
I have done some research and i find how to flash a stock recovery (i did it with fastboot) but now i'm stuck. I reboot with holding power+volume down to get acces to the recovery, then i choose it and the update icon appear but then i have an warning panel with a phone on his side (i hope you know what i'm talking about..). Now i have a boot loop and i don't know how to fix that..
I hope someone will be able to answer me !
And sorry for my english, tell me if something is not clear.
P.S: If possible, i would prefer not having to lose my data
Did you flash the stock recovery or were you stuck before that??
Yes i flash it and i get stuck after. Now when i boot i press power+volume down and when i am in the menu i choose "Recovery", a black screen with the icon update, and then the same black screen but with a phone and a warning panel on his side.

Are you sure you got the right stock recovery, did u modify something in your rom, did u change the stock kernel to custom kernel ?
did u restore to fully stock (not just the recovery)
stock rom
stock kernel
stock recovery
I have a stock rom and a stock recovery (i guess, i have downloaded a file named endeavoru_recovery_signed.img) but i don't know for the kernel, how can i check it? The only thing i did was unlock the bootloader and root the phone, does it change the kernel?
it's much easier if you just relock the bootloader and run the RUU.
I would prefer to keep my data and installed data if it's possible.

No that does not change the kernel.
Put the phone in Fastboot USB mode and Do
Fastboot getvar version-main
You might have a old recovery installed.
Ok i have the version 2.17.401.2, is it good or not?
Edit: It's the ICS version so it isn't the right recovery version, right? I have to search a 4.0.4 version? The higher version of recovery i have found is version 1.29.401.11
This is the 2.17 stock recovery
http://db.tt/U5CK4noo
If your main version says 2.17.***.** you need this recovery !
Thank you for the link, i flashed this recovery but i still have the same problem :-/
Edit: Now i can acces to the recovery menu when i press power+volume up on the screen with the warning panel. I have some error message:
E:Can't open /cache/recovery/command
E:failed to mount /sdcard (No such file or directory)
E:failed to mount /sdcard (No such file or directory)
E:failed to mount /sdcard (No such file or directory)
Edit 2: I forgot to say that I wipe and format some things (don't remember which one, i try to find again the tutorial that i found) but nothing that delete data.
Edit 3: Ok i find it, that's what i did:
Wipe the cache partition
Go to Advanced and wipe dalvik and batt stats
Go to Mounts and Storage and format system, then data, then cache.

The errors ...that's fine because the stock recovery can't mount the sdcard that's normal.
The wiping caused it that it not boots. You did practically a full wipe ! Do you have the RUU or a nandroid backup from the rom.
Give your cid here, we have the main version already ... going back with a ruu is the easiest now....

OMG...
Dude, you better go RUU way, really.
I assume you have a Windows computer and HTC drivers are installed on it properly.
Looks like you've lost your data and cache but you may still have the data in your sdcard, so first, try to backup them...
Launch the CWM recovery... Connect your USB cable to the phone and then in the CWM custom recovery window, go to "mounts and storage" and select "mount USB storage".
This shall allow your computer to access the storage of your phone.
You shall see a drive on your computer named "HTC STORAGE".
That is your phone storage so copy everything you think that you need.
Then...
Download the correct RUU for your phone >> http://www.htcruu.com/?dir=Endeavor
Note: One X is called "Endeavoru", if international model. Otherwise "Endeavor".
When downloaded, power off the phone.
Press Vol down and Power buttons together till you reach the HBOOT screen.
Select fastboot.
Plug your USB cable and "fastboot" will change to "fastboot usb".
From your computer, which is on the other end of the USB cable, launch command line, from the folder which you keep your adb, fastboot files.
type "fastboot devices" and hit enter.
You shall see some serial number if you have correctly installed the drivers of the phone and if it is correctly plugged.
Now, you need to re-lock you bootloader.
This is required for RUU to perform; if your bootloader is not in "locked" or "relocked" state, RUU won't perform.
Next, type "fastboot oem lock" and hit enter.
Now, bootloader is "relocked".
Now, run the RUU executable you've downloaded and follow the instructions on the screen.
This will take you back to stock status, then, without messing with it, do the 4.1.1 update from system settings and right after your first boot of 4.1.1, go to CWM recovery again and get a BACKUP.
Good luck.

[Q] "Can't mount storage" error after formatting cache in CWM

After using for some days with sling rom 2.1 my phone was running li'l bit slow. So i went to CWM recovery, formatted the cache partition. After that when i reboot to system, it shows an error like this:
" SECURE BOOTING ERROR
==========================
Cause: Device unlock, So boot success "
and goes to recovery every time instead of booting into phone. When i didn't understand what i did wrong, I decided to flash a rom from the memory card and it shows me another error "Can't mount sdcard". After that i wanted to flash with kdz but surprisingly i couldn't get it to the download mode either. It just goes into recovery. What should i do now?

How did you go to download mode? Try this:
- Turn off device (in recovery: advanced > power off).
- Wait 20-30s. Unplug cable.
- Hold volume up and down + plug quickly.
Try several times.

I have tried with this key combination like 20-30 times but no luck Now I'm fearing of loosing my beloved device...
Go in cwm mount system then format system it worked for me i don't know if it will work for you so i don't hold me responsible over this but if you can't do anything else you can try it

Stuck on load screen, unabled to enter recovery, adb erase cache has no effect

So my second zenfone is dead.
Like many others, it gets stuck at the asus loading screen with the spinning wheel.
This did not happen after any obvious action, like an update - it was just turned off when i woke up, and wont load beyond the spinning wheel of death.
I have booted into fast boot mode (power and vol +), selected [recover mode] and got the broken android logo.
I then hit power and vol+, then release vol+ as suggested, but instead of a menu, i get a bunch of yellow console output, 3rd line of which is:
E: failed to mount /cache (invalid argument)
This appears for less than a second, then back to flashing broken android logo.
Repeating ( power and vol+, then release vol+) results in the same briefly visible console output
I turn off, and reboot into fast boot mode, and try using adb.
I enter the command 'fastboot erase cache' and it completes in 0.4 seconds, no errors. Has no effect on phone (reboot stuck loading, recovery mode same error as above).
Next i try 'fastboot format cache' - the command appears to work, but again completes in just over a second, and has no effect on the phone.
The only info i could find directly relating to this error is on a random .info website, so im reluctant to follow the steps:

Anyone here solved this issue? Or is it time for a warranty claim?
Thanks

Just don't do step 15 (factory reset) if you want to keep your old data.

Thanks for the link - it looks much the same as the one i posted, with the addition of flashing the system image.
Do you know if there is any danger in trying without flashing system 1st?
Also, have you used or seen this method used specifically to fix the mount failure i have described, or its just a general 'de-bricking' guide?
Finally, do you or anyone else have any insight into why this might have happened in the 1st place - as i mention, i did not do anything beyond normal use prior to the issue.
thanks
Sounds like the recovery corrupted... could be a range of things from improper shutdown to an improperly coded app that caused the error. If you want to flash just the recovery and see if that fixes it, go right ahead, but don't forget to erase your cache after you flash recovery.
Whenever I get stuck in a bootloop, the steps I follow are:
1) clear the cache and see if it fixes it, as something might be there that's preventing you from booting
2) flash the most current firmware to see if it fixes it, as something might have modified a section of one of the partitions that's preventing you from booting (make sure to clear cache after flashing)
3) contact support because it's more likely hardware failure
There's no danger in flashing any of those partitions, at most you'd lose the Xposed framework, root and busybox - which are easy to reinstall. It doesn't affect much else, and your info should be intact. I would advise getting the firmware from a reputable source though... I just get it off the Asus website, then root the phone after.
Try reinstall recovery
Download stock recovery(there is download link from zenfone2 index)>go fastboot mode>then flash recovery using command :
fastboot flash recovery (recovery image name).img
>Reboot to recovery>adb sideload full firmware

Mi Max 3 stuck in fastboot

Long story short, I tried to flash a global ROM on my Mi phone. However, after a few unsuccessful attempts at doing so, my phone is now stuck in the fast boot screen.
I tried all I know and what I can find online, but the problem still persists, where when holding the power button it would boot to main power screen and then make a buzz and go back to the fastboot screen.
Have tried:
- Resetting through recovery mode (pow + vol up)
- plugging phone into my computer to reflash the ROM (error remote: unknown command) / on my phone it would switch out of fastboot and instead display this message: "press any key/button to shutdown"
- pow + vol down (held for more than 1 minute)
- pow (held for more than 5 minutes, everytime it would boot and then boot back into fastboot mode with the buzz in between)
- ADB console commands:
- fastboot reboot
- fastboot device
- tried using MiPCSuite, plugged my phone in, but application didn't detect my phone
- running all applicable applications as mentioned above as admin
- when resetting phone progress bar would stop at 1.03% then it would say reset completed (I don't think did reset the phone, but whatever...)
- tried different ROM versions, Global and China (Once again it would either switch out of fastboot on screen OR in the flash tool it would display the error "unknown command" which I assume would be something to do with the communication between my PC and the device itself)
At this point I don't know what else to do, watched every tut on youtube, read pretty much all the forums I could find related to this issue.
Any help would be much appreciated!
Is it locked or unlocked?
I whould try to update firmware, then recovery (wipe all at this point) and at the end ROM (format data, wipe dalvik and cache at this point), always worked for me. But - the phone should be unlocked for this

I have tried going into recovery mode and wiping all data, and trying to update the firmware via the flash tool. But as I said above I can't it gives me the error "error: FAILED(remote:unknown command)" and since I can't get into my phone, I can't use mipcsuite either or enable and settings.
Note - wipe data and format data is not the same
I've stuck with some stupid error ("erase all data" message and reboot to twrp) for hours until I formated data

Made an stupid error when flashing my phone - help needed eventually

Hi,
have to say it was my first try ever to flash a phone.
I've followed the ReadMe-Thread to the letter and with a little bit of try&error I got it done smoothely until I came to flashing the CustomRom "lineage-18.1-20210311-UNOFFICIAL-hima".
The instruction is " Choose "Wipe" and wipe everything except for "Micro SDcard", "USB-OTG" and "SD-Ext" via the advanced wipe. ".
What I did was exactly the opposite. I did mark "Micro SDcard", "USB-OTG" and "SD-Ext" and wiped it. There was an error message but as I was shocked about my mistake I can not remember any detail.
I've done it the right way after this error without booting the device and as far as I see it the flash was successful. The phone now starts Lineage and seems to work. Not sure yet as I have not got a new prepaid SIM but it's underway already. But the "rest" of it works. Have installed some apps with adb already.
BUT: It seems as I have destroyed the recovery mode at least. When I try to boot into recovery I only get a normal boot into LineageOS. Means that I start to bootloader mode and then select "Boot to recovery" the screen becomes black and then after some time the LineageOS starts. I can also switch between download ans bootloader mode but can not reach recovery.
AND the htc_fastboot command does not have any effect, will say NO devices are visible.
May someone in the know please enlighten me what I've done and how I may eventually recover the recovery mode?
Thank you very much for reading this and if I've written absolute nonsense here please bear with me, I'm German.
I guess you can flash custom recovery again using fastboot and reinstall Lineage!
Thanks.
When I try to use htc_fastboot there is no reaction and "htc_fastboot devices" shows nothing.
Same problem with me. to negligence, i didn't do this " "Wipe" and wipe everything except for "Micro SDcard", "USB-OTG" and "SD-Ext" via the advanced wipe" and installed the lineage 18.1. and now I don't have Recovery and the phone boot to lineage os but it will not boot totally. it will shut down and then boot again. (loop)
please help me.
I can boot to download mode
unlocked
s-on
Os-4.28.401.3
any help is much appreciated. thank you in advance
Hello,
I have a similar problem. It is an m9 with an unblocked bootloader. I got it from a colleague.
It had a cyanogen mod and TWRP on it. I set the cyandogen mod to factory settings and then activated the developer options so that I can boot directly into the recovery from the operating system.
It also worked perfectly. Then I wanted to update TWRP with the TWRP app.
It worked until I was asked whether I wanted to flash TWRP into the recovery or into the boot.
I chose recovery and thus rendered the phone unusable. It only boots into the bootloader or into download mode.
My attempts to flash a stockrom via adb or an executable file on a windows pc failed.
With the latter, the smartphone at least responds via the usb port. But so far I have not found the right RUU file for the phone.
Unfortunately, it also does not respond to 0PJAIMG.zip files on an sdcard formatted with FAT32.
Is there a way to force-flash TWRP onto the phone?
Many greetings
Draal
