[Q] I do seriously need help with my M8

Hello people,
i've bought a fresh (kinda thought of) HTC M8 blue color from a guy. It looked really nice outside & inside, not a single scratch, not laggy and cool phone so i decided to buy it.
Once i got home i saw that it's broken or something, that guy doesn't answer his phone so i think he lied to me.
About the problems: flashlight doesn't work, phone unlocks after 3 sec~ once you press unlock button, g-sensor doesn't work, and if you turn it off it doesn't turn on without factory reset through recovery mode, that's only thing you can do once phone got shut down or battery drowned. I've tried to install custom ROM's, still the same, can't even back to stock firmware now without Sunshine thing for 25$, but i think it's not even worthy if the phone is broken (?). Maybe some of you have passed through the same or kinda similar problem? Would be nice to hear something, and i could even donate for you if you would decide to help me pass it through. THANKS, community! :good:

yes you will have to go into fastboot usb mode to get the full info, the command is fastboot getvar all post the info here without imei and serial number please.

quite an easy one to try and sort out, but backup anything you want to keep first and then follow this post, its the same files for your phone:
ok you have to downloaded this file, put it in the same folder as ADB and fastboot files and rename it to RUU for ease: https://www.androidfilehost.com/?fid=95916177934518148
you will need to use the HTC_fastboot.exe to flash it, normal fastboot wont flash Lollipop RUU's, get the htc one from here and put in the same folder as your RUU.zip and other adb and fastboot files: https://www.androidfilehost.com/?fid=95916177934550031
then do these commands:
fastboot oem lock
fastboot erase cache
fastboot reboot-bootloader
fastboot oem rebootRUU (phone screen should go black with sliver HTC logo)
htc_fastboot flash zip RUU.zip (YOU MUST USE THE HTC_FASTBOOT to flash the zip, the normal fastboot wont work, now leave it alone to do its thing, takes about 10 mins, no need to issue this command twice as its automatic with the htc_fastboot)
now make sure when its finished and you have a command prompt and that it says successful at the end and OKAY
if so then type fastboot reboot-bootloader
now fastboot reboot
this will return your phone to full stock and fix any messing about that the last owner did to it.

I did that, it went successfully, but all of the problems still remains.. Now i'm starting to think that it's motherboard is faulty or some part, i don't know.. But i know, that i lost money by buying it, that's all.

Soft Bricked the HTC One M8

HTC One M8
Unlocked and S-off
From UK so with international network
Cyanogenmod 11 i think
Clockwork recovery
Soooo i bought the M8 secondhand with Cyanogenmod installed, however, i couldnt do any updates due to error status 7. i tried the normal fix (delete code which checked authorisation of phone) but to no avail. since then the error came back and i managed to get a different error on reboot: "root access possibly lost. fix?". I've cleared cache(s) and done a factory reset. No matter what i pressed it would be in a boot loop. I can still get to bootloader and recovery. then i tried to change the recovery to TWRP however when i try and fastboot, my device is not recognised by my laptop so i cannot add the ADB driver to the device.
sorry for sounding very vague / idiotic, i have no idea what i have done and no idea what i am doing to try and fix it. that means sadly i will need to be spoonfed the fix. if you need any more details or pictures of the problem let me know
thanks in advance

Are you trying to update to CM12.1? If so, the error is for a reason, and not to be bypassed in the way you describe.
If you are on an hboot older than 3.19, I don't think it will work with CM12 and 12.1. You'll need to update hboot (and rest of firmware, preferably) to proceed.
Also, CWM may be too old for CM12 as well.

Not sure what you mean here. Are you trying to install HTC Sync (and corresponding driver) by connecting the phone?
You can just do an XDA search for "simple adb" and you will find a couple really easy adb/fastboot installers.

how do i see what hboot i am on? and how would i update it?
i've installed HTC Sync but it doesn't recognise my phone being connected (so i cant view any files on the phone) and i've installed a simple ADB/fastboot but i can't see the driver option when trying to add it to my phone on Device manager. i have got to the stage whereby i have the ADB/fastboot folder and have the TWRP file in the same folder, just i cant get any further.
where would i begin getting to cyanogenmod 12.1, or would it be easier to revert back to a basic android os?
i know this is probably incredibly frustrating for you as i am a complete novice, but i greatly appreciate your help
i would post pictures to help but i cant as im a new member, i will when i can

This in itself does not mean the phone is not connecting by fastboot. And fastboot is the important thing here, so we can update TWRP, etc.
Try rebooting into fastboot mode, and try the command and see if your phone's ID is returned: fastboot devices
If you don't get the phone's ID and just "waiting for device" you do indeed have some type of USB connectivity problem.

Boot into bootloader, andyour hboot number is listed near the top of the screen.
Since you are s-off, its fairly easy to update the firmware (and I would suggest to update all the firmware, not just hboot) by flashing the proper firmware.zip. But let's determine whether that is even the problem, before we worry about flashing firmwares.

hboot is: 3.16.0
also my phone is detected by my laptop so all is well there
i have installed a simple 15 second ADB file but am unsure how to proceed from here

Your firmware is very old, so will need to be updated to run CM12.1. Also, newer versions of TWRP will not run with your old hboot.
Do a fastboot getvar all, and post the output, but delete your IMEI and serial numbers (as these are private info). Need more details on the phone (particularly CID) in order to know how to proceed.

I'm going to suggest WWE/International firmware. The updates are available way before O2 updates.
Download this firmware (it also includes TWRP2.8.4.0). Rename it to firmware.zip and place it into your fastboot folder.
Next, boot into fastboot and change your CID to superCID (it won't flash with the O2 CID)
fastboot devices to make sure you are connected (a bunch of letters and numbers/your serial# means you are)
fastboot oem rebootRUU (a black screen with the HTC logo means you are in RUU mode)
fastboot oem writecid 11111111 (eight ones) You are now superCID!
Now flash the firmware
fastboot flash zip firmware.zip
If you get "error 90 hboot pre-update" (and you probably will with how old your current firmware is) run the same command again and the firmware will flash properly. The first run only updated your hboot.
The process will stop at 75% to 90%. That's normal and gives you a chance to check your console output. The last few percentage is the reboot.
The bar will fill to 100% after you enter fastboot reboot-bootloader
That's it. Good luck!

thank you both so much! so now do i just download the appropriate cyanogenmod version and flash it over?

Yes. But there are more ROMs out there as well. Try them out and find the one that suits your needs best.

hi there i have htc one m8 rooted s-on & software status is modified
i got a new update so i flashed the stock recovery then downloaded the update and pressed install
it was loading the update and suddenly the screen frozen on the htc ONE screen without responding
i tried the volume down + power button nothing happened then i tried volume up + power button
it reboots and freezes on the same screen - tried to remove the sim & sd card but nothing happened
what should i do plz ???
cid : htc_j15
build number : 4.16.401.10

fastboot reboot without usb debugging enabled - phone now bricked?

I typed fastboot reboot into cmd while usb debugging mode was not activated in the phones settings, and now the phone has booted into a blank screen. Is there anyway to get out of this?

The phone is on, but a blank screen? Or not responsive at all (like its powered off)?
What happens if you hold power + vol up for 30 seconds or more? This should force a reboot in virtually all situations (except a true brick). But what it reboots to, is another question.

The phone was stuck on the bootloader screen. I could connect the phone to cmd and got serial number etc, but as a soon as I typed fastboot reboot into cmd and hit enter, the phone went blank screen and never came back on. I have tried all button combinations loads of times and left it on charge for hours.
I think the phone is done, all I see in device manager now is QHSUSB_BULK. Shame since it was on bootloader screen before hitting fastboot reboot and could have been repaired.

Did you do any fastboot command that may have led to this?
Did the phone previously boot into OS, then was unable to (stuck on bootloader screen).
I guess what I don't understand, is the exact sequence of events; and you exact actions, commands, etc.

when I got the phone it would not boot into recovery or OS. I tried reboot from the bootloader screen and the bootloader would reload. I tried recovery from the bootloader screen and the bootloader would reload.
I was advised to try this:
http://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
When I tried the first step; fastboot reboot-bootloader - my phone switched off and has never switched on since.
Im not 100% sure what the previous owner did to the phone, it did say software modified at the top of the bootloader screen, but thats all I know.
This was the fastboot devices output

Thanks for clarifying. Unfortunately, there wasn't anything obviously wrong done with the phone (that might lead us to a fix); and it doesn't look good if its charged for several hours, and no response to button combo power+vol up.
Try the button combos with and without the charger connected (a few folks have had luck with this - for no discernible reason). Other than that, I don't think there is much you can do, short of maybe JTAG.
A couple suspicions (and they are just guesses, really):
1) emmc was already fried, which caused the phone to no longer boot into OS in the first place. Then it eventually went from "virtually" bricked to a black screen brick when you were trying to work with it (by no wrong actions of your own). We've seen a couple instances on this forum, where this appeared to be the case.
2) previous owner flashed something they shouldn't have. Similar to case #1 above, just waiting to go to full-on black screen brick. But the effect of flashing something that bricks the phone is usually more immediate.

HTC One M8 stuck on bootloader

hi, thanks for letting me join. if this is posted in the wrong place im very sorry. 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
LOCKED
SECURITY WARNING
THEN LOTS OF GREEN WRITING.
any help would be great. thanks

You can follow this post instruction ( skip the part of relocking bootloader )
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

you can't flash RUU in recovery mode !!!!!!!!!!!
you tried to flash using sd card ( formatted as fat32 ) or the fastboot method ????
you said earlier your bootloader is locked
if it's unlocked relock it

Sir you are a GOD!!!!!!!! Phone is back to normal.
I followed your instructions and my M8 is now back to normal.
Thank you so much for your help and time. You saved my phone.

htc bootloader info

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

My responses to some of your points below, in red font:
gda_scooby said:

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.
