HTC One M9 only Bootloader, no Download or Recovery modes
 

Hi, I've used XTC2clip successfully on M8 and M9 phones before, but I now have a M9 that only boots into Bootloader mode and so far I've been unable to sort it out.
The symptoms are that when started from off condition the white screen with green HTC logo appears with the red text 'This build is for development purposes only..... etc' underneath for a few seconds then goes to the Bootloader screen with 'Software status: Modified', 'LOCKED' and 'S-OFF' at the top.
If 'Boot to Download Mode' is selected it goes to a black screen with HTC logo also with the red text underneath as above. After about 30 seconds the screen goes to the white HTC screen for a few seconds then back to Bootloader.
I've tried fastboot flashing various hosd files, but without any change in condition. Unfortunately I don't know the history of this phone so don't know what the version-main number is.
I've read in various places that this condition can be as a result of emmc hardware failure, however I would like to explore possible cures before writing the phone off as dead.
Is there any way of getting more information from the phone using commands in bootloader mode?

Hello!

You can't get more info in bootloader, there are no commands for this.
Good that your phone is S-OFF.

Were you able to flash at least one HOSD successfully? If so, what was the name of the file?

I tried to reply with more detail, but was not allowed to send because the message said that I cannot use links until I've submitted at least 10 posts.
However there were no links in the post so I've informed the Webmaster and waiting for a reply.
I have a total of 7 posts (8 with this one).

any solution? i have planty phone

if after flashing hosd still no download mode than u can repair via emmc tools

You can download this:

Unpack and copy all files from HTC_M9_Repacked into xtc2clip except 0PJAIMG_UnZipped.zip
Then boot into FTM mode.
You can check Flash & H/W info.

If failed to boot into FTM then there's a hardware issue, i guess eMMC problem

Not yet, but still working on it!

Is emmc DL Tool suitable?

Emmc change/repair tools required

Since my original post I did boot into TWRP from the bootloader using
HTC_fastboot boot twrp-3.2.2-0-hima.img and then was able to to use ADB shell getprop to get more information. In the result there are references to OmniROM. The main one being [ro.modversion]: [OmniROM-6.0.1-20171209-hima-HOMEMADE]. I assume that someone has previously flashed OmniROM and this has caused the brick. As far as I know HTC One M9 is not supported by OmniROM. The CID is O2___001.
I tried all the hosd files without success.
Also tried various functions within TWRP but always end up with:
Failed to mount '/cache' '/system' '/data' (Invalid argument).

What was previous stock rom version before omnirom ?

I acquired the phone with the condition existing so unfortunately I don't know its history.
I assume that it originally had O2 UK stock ROM. I've tried restoring TWRP O2 L50 and M60 back-ups, but get the 'Failed to mount' messages as mentioned previously.

failed to mount message mostly emmc issues rarely software problems

It looks like eMMC, then you need a in circuit programmer to check eMMC.
Here is a nice example how to do this.

You could boot into stock recovery, if you get a red exclamation mark then press and hold power and pres vol-up and release. You should get into terminal mode and able to wipe. If you get CRC errors mounting partitions then eMMC is bad.
Also in download mode > System info you can see eMMC type & SMART life bytes.
Only thing you can do then is to replace the eMMC chip.
There are Samsung and Hynix chips, the last is known to go bad within 2 years.
