[Q] Unable to flash firmware

So I've just picked up myself a HTC One M8 on Optus in Australia, first thing I did was install TWRP and root the phone, only to discover that there was then OTA updates to install, so I installed a stock recovery that I downloaded from here, ran the process to get the OTA update and it started but displayed no progress on the screen, just a HTC logo that remained there for at least 20 mins, so I rebooted the phone, this time the logo only stayed up for about 4 mins, the device rebooted and it was updated. The only problem was that it looks like the firmware hadn't installed/crashed/shouldn't have been rebooted and I had no wifi (Whenever I tried turning it on it remained off and no networks were shown) so I'm assuming the firmware update failed when it either crashed or I got too impatient (20 mins isn't impatient is it?).
I tried putting the firmware.zip from the OTA install onto an SD as 0P6BIMG.zip which gave an error:
Loading [0P6BIMG.zip]
Checking
Wrong zipped image!
When trying to flash with fastboot I get:
fastboot flash zip firmware.zip

Any idea how I can flash this stock firmware to the device?

First of all, I assume you are trying to flash the firmware in rebootRUU mode right? or else it will fail
Second can you post the outcome of "fastboot getvar all" hiding first all the sensitive info like imei.

I connected the device to my PC with internet passthrough and there was another OTA update which I installed and looked correct this time and didn't take as long, I have my wifi back but I noticed in the earlier firmware there's a adsp.img that is missing from the latter. I'm guessing it's to do with the 'Enhanced sound' etc. features that came with that update so I'd like to check if it is on there.

This looks like the latest firmware for Optus so you must be ok.
(bootloader) version-bootloader: 3.18.0.0000 - This is the latest hboot version
(bootloader) version-baseband: 1.19.21331147A1.16G - This is the latest radio version
(bootloader) version-main: 2.07.980.2 - This must be the latest firmware but check your ROM settings about Software info to see if it's a 4.4.3 android version.
But it all looks good to me.
Edit: reboot to bootloader and check the dsp version. If it's v45.2 (if my memory serves me right) then you are on the latest adsp.img as well

Android version is correct but DSP is not up to date so it looks like the firmware didn't install that first time. Bootloader tells me DSP is @ V26.2 (Obviously someone doesn't like subversions much!)

Well maybe that's the latest DSP version that Optus released, i'm not really sure to tell you the truth. But still you have no other choice now as with s-on i don't think you can flash older firmwares.
Nothing to bother yourself though as you are on 4.4.3 with the latest hboot and radio from your carrier.

If I restore a stock NANDroid backup, will the OTA file update the firmware again or is the firmware version check saved elsewhere?

No, nandroid backup doesn't include firmware (hboot,radio,adsp,etc)

I mean, if I install a nandroid backup, can I apply the OTA updates (As it will be a base version) and will the OTA firmware files still install? Or does it skip the firmware install if it detects a newer version already installed?

i'm not really sure about this and you can try it after taking a nandroid of your current setup, but i believe the OTA will skip the rom installation since it will find a newer firmware.

Correct, OTAs need to be installed sequentially (no "downgrading"), so it will fail when it sees a higher hboot number.

Problems With My M8

Hello Friends:
I've a big problem on my M8: It doesn't load S.O and remains only in fastboot mode. Yesterday, when I arrived to my home, suddenly reboots and stayed in fastboot mode. I share with you screen captures of my M8 ASAP. I tried to install in fastboot mode a stock RUU but it gives me error code in the bootloader process.
Please, i need your help or any advice to know how to fix it.:crying:
Many thanks and salutes from Chile.

I can't load SC yet...the forum won't let me do it. :crying:

What CID, hboot, radio, number, OS number (in bootloader)?
What is the filename for the RUU you tried?
What is the specific error message when running the RUU? Try running it a 2nd time (not unusual for it to fail the first time).

I asked for the filename, that isn't a filename. I asked for a reason, since folks often think they have the right RUU, when in fact is completely the wrong one.
But probably irrelevant anyway. Based on the error message, you may have a fried emmc.

{HELP} HTC M8 won't open recovery

Hello.
I have M8 in bootloader and it wont bootup, wont go in recovery etc. Everything I press, it returns to bootloader.
I don't know what to do, I already read all day stuff on forum and I can't do anything.
(I bought the phone like that)

You have to give more informations - firmware versions,boot version etc.Also try to flash some recovery.Do you get any error or ? Can be hardware problem if everything doesnt work...

What version TWRP? Your firmware (hboot, radio, etc.) is really old, so most any version TWRP 2.8 or later will fail or cause other issues.
My recommendation would be to update to current firmware (by RUU may be the easiest way) then try to install TWRP again. If that is what you want to do, then I can give further info.
Also would be helpful if you do fastboot getvar all (if you know how) and post the output, so we can get more details on the phone's status (be sure to delete serial number and IMEI before posting).

I'd be gratefull if you guide me through firmware upgrade.

My advice would be to run the AT&T RUU (download link and instructions near the bottom of the following): http://www.htc.com/us/support/htc-one-m8-att/news/
You'll need to relock the bootloader to RUU with command: fastboot oem lock
RUU will wipe the phone, but it sounds like you haven't even had a chance to put any personal data on it yet, anyway.
RUU will put you on an updated, fully stock image including updated firmware. Hopefully will also get the phone booted back into OS.
After that, you can unlock the bootloader again, and flash TWRP if you like (to root, flash custom ROM, etc.).

Let me see if I undestand well.
1. Relock with that command
2. Double click od RUU file (I guess that ruu is system file and opens with CMD? ) and follow steps

RUU is a Windows executable program. Just double click it, and it will lead you through the rest (very little action needed on your part). You don't run it from CMD.
If the phone is booted into OS, the RUU should reboot into into fastboot-bootloader mode. If not, you will need to boot into bootloader-fastboot mode yourself.

My HTC One M8 is secondhand and Ive had it for about 1.5 years now. the other day it crashed and ended up in a boot loop. i have tried lots of stuff but to no help. is there a way i can load stuff on to the sd card to fix it. on two occations it has got to the setup screen but errors would not let me type wifi password so had to hard reset.
ive tried hard reset
ive tried recovery
ive tried wipecache/factory reset
ive tried factory reset......seemed to work on two occations but on setup came back with sense input error and google error.
the phone had all the newest updates and was unlocked to any network.
on bootlader its says....SOFTWARE STATUS MODIFIED

https://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
easy way :
Download the RUU.zip from the linked post and rename it to 0P6BIMG.zip then put it in your external sd card root and reboot to bootloader ( hboot )
It will ask you to update confirm it and wait for a few minutes till it finish and ask you to reboot,that's it

I followed your instructions and my M8 is now back to normal.

Bootloader info is great. But if you are asking for help, you really need to tell us more about what is going on with the phone. I gather from the subject of the thread, that your device is stuck in bootloader. But how did it get to that state? Did it just happen spontaneously (while using the phone, or when you tried to turn the screen on after idle for a while, etc.?). Or were you trying to do something, like unlock bootloader, install custom recovery TWRP, root, flash custom ROM, etc. Or some other function, like install an OTA update? If trying to flash something, provide exact details like version numbers, file names; as well as exactly what happened when you tried to install (changes to status of phone, error messages, etc.).
Have you tried anything so far to resolve the problem? If so, describe exactly what you tried, again with any applicable file names, version numbers, and outcomes (error messages, etc.).
The more specific details you provide, the better we can help you.

Stuck can't get phone to connect to PC
Hi, I have an HTC One M8 which I just got secondhand, it's stuck on bootloader screen, usual messages ('modified' 'locked' etc)... I followed the instructions for RUU flash on other posts and am all set to go, but annoyingly my phone will not connect to any PC I use....I have installed the drivers etc...I am well used to using ADB, just can't get the phone to be recognised.
I also can't boot into recovery, just ends up back in the bootloader screen again. If it does try and boot it hangs at the logo screen....
Would welcome some ideas on where to go next....

adb won't work in bootloader mode, by definition. You want fastboot for running RUU, which is related to adb, but with important differences.
As long as you are in bootloader-fastboot mode (fastboot is highlighted near the top of the bootloader screen) which is often default if phone is connected by USB, you should be able to use fastboot. Try the command:
fastboot devices
And as long as the phone's ID is returned, you should be good to go.
If the command just results in "waiting for response" or an error, try a different USB cable, or a different USB port on your PC.

Still no go... Tried connecting on different ports and with different cables but just doesn't seem to work. Best I've managed is with the Aruuwizard tool which seemed to connect but I couldn't get much further. If I run fast boot devices it returns no device... Just a blank line....

Hello. I have a similar problem with my HTC One Mini. It's stuck in fastboot mode and trying to reboot/boot into recovery or factory reset does nothing...goes black for a sec and then back to fastboot mode. Bootloader is unlocked and it's S-ON. Any help much appreciated! Cheers!

HTC m8 phone keeps booting into fastboot mode

hello,
after root my phone
every time i try to put it in recovery mode it goes back to fastboot mode ..
even if i tried to flash a recovery on it , it would boot to fastboot mode
even when trying to install a official htc software update it just boots into fastboot ..
now i want to get it back to stock..
please help me !!

Need more info.
What version SuperSU? What version TWRP?
What "official update" file did you use? Was it an OTA or an RUU (list the exact file name)?
Also, do fastoboot getvar all, and post the results (delete IMEI and serial number before posting).

In addition to the fastboot output, I asked 4 questions, none of which you answered.
You have the M8 eye, not the "standard" M8. Far as I can tell (not many folks on xda have the "eye") you need a special version of TWRP for this version. You can try the right version TWRP, and flash SUperSU again, see if that helps. No idea if this version TWRP will work on not (can't personally vouch for it): https://forum.xda-developers.com/htc-one-m8/general/m8-eye-recovery-root-t3159648
Depending on what you did to the phone by flashing the wrong TWRP, it's hard to tell what the proper way to proceed.

hi
can i have stock recovery download link in that phone pls

I have a similar issue, but with a standard M8
£10 off ebay, so not expecting ,much (also means no known history) . 1 week old noob reading here and flashing phones
1) only boots to fastboot, and even does this when you leave it powered off, but charging.
2) select hboot, then to recovery, recovery doesn't run, just resets back to fastboot eventually, after screen goes white not black.
3) can partially speak to phone in fastbook and get versions ok (included below)
Getver all as below:

4) never been able to boot to full o/s so not in developer mode, so cant get response in adb (and dont know how to use this anyway)
5) tried RUU.exe - fails with usb error after it tries to restart bootloader
6) tried ruu.zip from memory card - fails with partition update fail
7) tried fastboot recovery image 6.12.401.4 and it fails to write - error is 'remote:signature verify fail'
8) random google lead me to fastboot oem reboot RUU which does this:
E:\android tools>fastboot oem rebootRUU
...
(bootloader) Error: Command never completed

aim is to get a standard phone working again
Thanks

ok got my unlock token, seemed to flash it, but no status change/reaction on phone and rebooting still shows locked
E:\android tools>fastboot flash unlocktoken unlock_code.bin

My responses to some of your points below, in red font:
gda_scooby said:
(bootloader) version-main: 6.12.401.4
4) never been able to boot to full o/s so not in developer mode, so cant get response in adb (and dont know how to use this anyway) That is correct, you will not be able to use adb unless you can boot to OS or alternately TWRP custom recovery. So you are basically limited to fastboot in the current condition.
5) tried RUU.exe - fails with usb error after it tries to restart bootloader There isn't a valid exe format RUU for your version number (6.12.401.4) so you are probably using the wrong RUU. What is the version number or file name for the RUU.exe?
6) tried ruu.zip from memory card - fails with partition update fail Exactly what partition(s) is it failing to update? What is the version RUU you are using? The only valid one for your version would be the RUU.zip from here: https://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
7) tried fastboot recovery image 6.12.401.4 and it fails to write - error is 'remote:signature verify fail' You can't flash an unsigned recovery image, unless the bootloader is unlocked. It also seems you are trying to flash stock recovery, and I don't see how that is going to help your current condition.

I think your best bet right now, is to try the correct RUU.zip which I linked above.
