phone stuck on HTC boot screen and other stuff

I recently got a htc one m8 that is stuck on the boot screen.
i can get into the bootloader and fastboot seems to work.
I seem to be able to flash twrp but when i reboot into recovery it goes right back to the bootloader
if i reboot normally it goes back to the bootscreen with the green htc logo.
if i try to go to hboot adb doesn't recognize the device.
so i'm stuck now. i've read several tutorials and tried various things but have no idea where to go from here.
i can tell you that the bootloader says its unlocked and that its set to s-on and there is no os installed.
help

Try fastboot erase cache, and flash TWRP again with fastboot.
What is your hboot number, and what TWRP version are you trying?
Also, was your phone recently updated OTA for the Stagefright patch? If so, its a known issue that this recent update does not work with TWRP for some folks.

This is as it should be. adb doesn't work in hboot. You need to be booted into OS to use adb, possibly will work in recovery (but you can't boot into recovery, so that doesn't really matter).

my hboot version is 3.19.0.0000
i am trying to flash the latest twrp
I have not gotten the ota, this phone has been sitting in a drawer for about 6 months so nothing new has been applied.
I will try erase the cache and reflash the twrp

What number TWRP exactly? And you're sure its the TWRP file for the M8, right?
I ask for the number, since I've seen at least a couple times where the person claims they are trying to use the "latest" or "current" TWRP. But when I ask for more info, it turns out the version is not even close to current.
Best to be specific when talking about version numbers.

Sorry the version I'm trying to install is 2.8.7.0...
The actual filename is twrp-2.8.7.0-m8.IMG
I also tried your advice and from a command window erased the cache and then reflashed. It didn't work this time so I'm downloading some older versions of twrp and will try flashing them.
One question. Does it hurt anything to erase multiple times or for that matter flash a recovery image multiple times. With my old Motorola it was recommended to flash multiple times.
Sent from my A0001 using XDA Free mobile app

oh, it worked. I am one step closer as it booted into the custom recovery.....whoohooo
I ran the command "fastboot format cache" from a dos prompt a couple of times, there were errors the first two times, then the 3rd time it created it without error.
ok onto the next steps that are in Vomers guides....
thanks for all your help

You are correct, that is latest version (and correct one for the M8). You might re-download just to eliminate the possibility the file wasn't corrupted.

If you are still intending on doing this, don't try any version older than 2.8.4.0 or so. TWRP versions much older than that, won't work on hboot 3.19. TWRP will install and seem to work fine, but after you flash the ROM, the ROM won't boot.

In the technical sense, the emmc chip does have a finite number of times it can be flashed.
But in reality, I think the number of times the emmc can be flashed before failing is (supposedly) something in the thousands.
Of course, things sometimes fail before they are supposed to, and every extra flash may put you closer to that point (in theory). But I don't let that stop me from flashing what I want, whenever I want to. And flashing recovery a few extra times is not going to hurt anything much IMO.

TWRP install on G4 H815 20A mm, doesn't stick (unlocked bootloader by LG official)

Hi,
I get TWRP running on phone , but when I boot into recovery , I always get the Standard Recovery, only option being a factory reset. Have opted for this factory reset and that is exactly what I get, no TWRP :crying:
Thanks

Also if you reboot to recovery through TWRP itself, it won't stick? If not: Is rooting an option for you? If yes: Try Flashify and flash it through this nifty little app .

This happened to me, too. Here is what i did:
Boot your device into fastboot mode via adb, straight up boot to recovery ("fastboot boot twrp-2.8.7.0-h815.img"), transfer the recovery image to your device, then flash it from within TWRP (there is an option for that within the normal install menu, its called "install image" or something like that). Hope this helps, it did for me.
Edit: Just realized you already found a solution. Never mind.

Ive the same problem. I unlocked the bootloader by the official procedure. Then i tried to flash twrp but it doesnt install truly. It always appear the stock recovery. I tried also clockrecovery but nothing. No recovery wants to get installed. Pls help me i want a custom rom on my g4

use twrp v2.8.7.0 on 20A mm....... adb reboot bootloader, fastboot boot twrp-2.8.7.0-h815.img, and to double check you have recovery,adb reboot recovery and then flash STOCK-20a-ROOTED

you can upgrade twrp with the twrp manager from playstore (once youve got twrp and root of course)

Try to wipe cache again, and install TWRP 3.0.0.0. The version 3.0.0.1 is really new, so maybe there are some issues.

I believe it is another issue...

I've tried with all the images below:
twrp-2.7.0.1-m8
twrp-2.7.0.2-m8
twrp-2.8.5.0-m8
and the problem is the same... after upload the recover image, I select RECOVERY in my phone but nothing happen

You might want to give HTC-fastboot.exe a try. I've had troubles flashing the recovery as well with the standard ADB toolset.
You should be ablo to find the HTC fastboot utility somewhere around here

Pretty sure TWRMP version 2.7 are known to cause problems with Android 5 or later; and not booting into recovery is the known result. TWRP 2.8.5 might be okay, but I'm not sure. I'd try 2.8.7 or (as I already mentioned) 3.0.0.0.

I tried almost everything, now I will try via Linux.
because via adb I did not get hit "device not found" (tried all drives and nothing happened) only via fastboot I got connection. I believe I first need to remove the S-ON.

Why do you think that? Folks always jump to the conclusion that s-off is the magical answer to all their problems. S-off doesn't have any bearing on the ability to install custom recovery, or whether you can connect to adb or not.
Waste $25 is you want (as sunshine is the only working s-off method), but it won't solve your problem.

Yes, I tryed 2.8.7 and 3.0.0, but dosen't work. After select RECOVEY , the phone vibrates and nothing happens, forcing a physical reboot it gets stuck on the HTC home screen.

Do fastboot getvar all, and post the output (delete IMEI and serial number before posting) so we can see more info about the device.
Something else is going on here.

Problem in TWRP?

I was on GPe so today i changed CID to SuperCID and my model is 0P6B13000,installed new firmware by given method in convertion post,installed TWRP and had no problem,but during factory reset i get Failed to mount /system (Invalid argument).Btw,after that i was able to boot in LineageOS,but was unable to boot into S-ROM,which i tried before flashing LineageOS.Also,i was unable to flash Stock Backup.Any ideas what's going on?

Fixed it.you can delete this

No idea if the comversion post is still valid for current firmware as I don't know which one you refered to.
It' a simple process - (after SuperCID done)
1. Install 6.xx firmware
2. Install latest TWRP 3.x
3. Boot to recovery (TWRP) - select wipe, advance, select format data - type yes. Then main menu select reboot - recovery
4. Once in recovery again you can install any ROM that you like.
To revert to Gpe, same process but using Gpe firmware for no. 1 and follow the rest

Well i used just the Instructions,not the old firmware.I flashed 6.xx firmware(From your collection) . Did it all but can't install S-ROM(only this one).I guess it's just ROM problem.Don't know.Btw i got stock twrp backup from your collection,but twrp doesnt recognize it(i have it on my ExSDCard,yes).Any ideas about that?

Did you do no. 3 ? That's very important.
What color is the bootloader now ? What is written on bootloader OS - xxxxxxx, any double no. ?
To restore a nandroid, you need to extract the zip and place it in right location as explained in its instruction on post #1.
In other thread you mentioned to convert it to tmob us.. why don't just use RUU ?

Another error occured during restoration. extractTarFor() process ended with ERROR:255

Which version TWRP that you installed ?
Used to get that error due to wrong version.
You can try 2.8.7.0 but don't accept any root offered by twrp.
Also you can try RUU - http://www.htc.com/us/support/htc-one-m8-t-mobile/news/
RUU will usually fix all errors unless it's hardware problem
Another thing .. you do not answer my previous question .. did you do no. 3 when doing conversion ?

Not needed for S-Off device.
What you need :
Windows with usb 2.0
Latest htc usb drivers installed which you can get by installing latest htc sync manager (then uninstall syc manager but leave the drivers)
A note about S.ROM - it may have alter your system partitiom & firmware because yours is S-Off. Always advisable to reflash firmware before installing other ROM. RUU will fix these.

I've just run RUU and ERROR occured around 50%.Now i'm left without everything ... Any way to get at least the stock recovery and stuff so i can get back to bootloader?

What error that you have ?
To get back to bootloader, press & hold both power & vol up buttons. When it turns black, release both buttons & press and hold vol down button only.
Also you can try to run command fastboot reboot-bootloader
Once on bootloader try to flash firmware again. (Your current bootloader has modified dsp which I believe comes from S.ROM)

I don't remember what was the number of error,but now i get htc logo with four exclamation marks(one in each corner)... when i fastboot reboot bootloader this screen appears.I ran RUU twice,same happend both times...

When you said this
but during factory reset i get Failed to mount /system (Invalid argument)
Did you do factory reset on bootloader while TWRP was installed instead of stock recovery ? AFAIK you're not supposed to factory reset on bootloader with TWRP installed unless it is stock recovery

I did Factory Reset before flashing TWRP.Now as you told me i flashed firmware again.Now my bootloader seems fine.I still dont get why RUU doesn't work.I'm S-OFF with unlocked Bootloader and as you said,re-locking is not needed.I don't get what's going on here ;d

Your first post made me understand that you factory reset after TWRP was installed .. because your problem always related to that.
Maybe try a different RUU, try the Developer Edition RUU.
Before that can you try to restore nandroid backup again using twrp 2.8.7.0 and see the error 255 still there.
Also you mentioned you can install LineageOS ?
How about installing other Sense ROM (other than S.ROM), try that too.

That's not normal. This is where you need to format data in twrp then reboot to recovery again. You should see internal storage

Does the "fastboot boot" command work for anyone here?

I'm using the fastboot binary from HTC's website. I tried to use it to boot TWRP without flashing it, but in download mode, it just hangs forever after saying "Flash images success (1/1)" and "Start downloading", with the cursor stuck on the second of those. The fastboot command is also hung, after printing "booting..." I eventually have to force reset the phone using all 3 buttons.
I also tried it from the bootloader screen and that just fails immediately, saying "booting... FAILED (remote: unlock device to use this command)" even though I'm unlocked (and S-OFF).
The reason I'm doing this btw is so I can try to back up the stock recovery before overwriting it with TWRP, but I don't know how to do that without root, for which I need TWRP... so if anyone knows another way, that'd be great too!

You need 2 phones.
Taken from twrp faq
6. How do I backup stock recovery prior to flashing TWRP? You can't. The "fastboot boot" command appears to be disabled on the 10's ABOOT, so TWRP must be fastboot flashed over stock recovery. You can however, extract the stock recovery.img from the OTA firmware.zip when it's received and use that to install the OTA.
[*]An alternate method to obtain a stock recovery is listed below, but it requires 2 devices (either owned by you, or help from someone else in the forum):
Someone fastboot flash twrp and immediately make a backup of boot and upload it to XDA.
Once the above is available, someone else download that boot.img to their device, and fastboot flash twrp to the BOOT partition of their device.
Once the above is done, reboot the device, which will bring up TWRP, and then backup stock RECOVERY in TWRP, and upload to XDA.
Then, from within TWRP, use the Image install feature in TWRP to flash the stock boot.img

They're probably pulled from the RUUs.

Download the latest RUU for your model, and use nkk71's RUU decrypt tool to extract the firmware (with the -f flag). The stock recovery will be in there.

Duh, OK, that should have been obvious. Thanks.

It's not obvious if you don't know about the decrypt tool, and a lot of people don't. You're welcome
