Hello, i've converted my htc one m8 uefa champions league edition to gpe and used it for a month. Then i started to have some problems, some apps disapeared, half menu dissapeared and i tried to restore to sense edition.
Got bootloops, got errors, got problems and i'm unable to get back to stock sense rom. I have supercid, i tried to do it trough RUU mode and through fastboot.
When i'm on fastboot mode i get an error like this: Update error. Device halted due to large image update fail. when flashing system.
In RUU mode i'm unable to install due to not enough space.
I don't get which is the problem and why i can't go back to stock.
Tried many firmwares and i can't.
Here i paste my var codes:

If it is not hardware problem, you can try a RUU to get back to Sense and see how it goes.

You need to use htc_fastboot.exe instead of using the usual/google fastboot.exe

You need to flash 4.16.401.10 firmware.zip before run the RUU

You need to change MID to 0P6B10000 first before you attempt to flash firmware.zip and RUU.zip or RUU.exe
change MID
install firmware.zip
install RUU.zip (you need htc_fastboot.exe)
or
install RUU.exe (you need windows PC with USB2.0 and latest HTC USB drivers installed)
I have an htc one m8 ATT phone I want to install the ViperOneM8 5.02 rom on which says I need to update the firmware to a marshmellow firmware I think.
Or the latest.
While I have found some documentation how to do this on the net, I am not sure where I obtain these files.
The firmware.zip I believe it is
Help on this would be appreciated
Right now I am using hboot 3.16 and twrp 2.7
I found this link
http://android-revolution-hd.blogspot.com/p/android-revolution-hd-mirror-site-var.html
https://www.androidfilehost.com/?w=files&flid=32780
and grabbed the 4.16.1540.8.zip but want to make sure I am grabbing the correct and latest version. Because I don't want to brick my phone
Post your fastboot getvar all result without serial & imei no.
You may need a different firmware if it's AT&T & S-On and also don't use that outdated 2.7 TWRP.

For some devices, TWRP 2.7 is recommended due to how older boot loaders may not take it well.
I like TWRP. When its workable, its array of tools is superior to CWM. But after I tried 2.8.x, I decided CWM or TWRP at or below 2.7.0.2 is safer and less crash prone.
When I attempted to boot to recovery it would boot loop. Please be mindful of boot signing. If you so slightly make your OEM software notice things a fuse will make your phone implode.

Read again what he is trying to do man ... he's going to update to Marshmallow firmware and that outdated TWRP 2.7 won't work for him (he can't even install his intended ViperOneM8 5.02 ROM with that outdated TWRP)
..... that's why I said don't use that outdated TWRP

Good point. For some odd reason CM pairs ROMs and Recoveries. If you check the Dev Auto update option would that be unnecessary.
It's been an itching question I actually had...
Sent from my HTC M8 GPE
? Mass Transit Honchkrow ?
I originally had twrp 2.8 on and tried to install the latest. But it was freezing because I think I need a newer version of hboot. which I have 3.16 on it.
I then downgraded to 2.7 to get it working. I installed ViperOnem8 Rom not reading the website successfully. but have issues with wifi, and 2 minute boot times.
"The 5.0.x ROM is based on HTC’s latest M8 Sense 7 Android 6.0.x base and requires you to update your firmware to at least the 6.0.x (Marshmallow) version! If you don’t you will run into some issues such as Wi-Fi not working or No Boot, etc.
We cannot install the firmware for you during ROM installation so you will need to take the steps to update the firmware on your own."
So I need to update my firmware. I have an ATT S-ON phone. But I have no clue where to get the firmware from, and make sure it is the right one and recent.
I need to update my firmware in order for this rom and a newer version of twrp to work correctly
ok, so
I upgraded to 3.11.1700.5 firmware I found. and that was successful.
Then I upgraded my twrp to twrp-3.0.2-0-m8 and that was successful
Now I am trying to install either Revolution Rom, or ViperOnem8 and both have the same problem. After install they keep booting into twrp and won't load.
I tried Cynamod and that installed and booted fine.
I believe both Revolution and Viper use the Aroma installer. Anyone know what is going on with these and a fix to stop it from booting into twrp?
Need advice

Wrong firmware. You installed an old version of GPE firmware.
You can't install Sense ROM like Revolution and Viper on GPE firmware.
I asked you to post fastboot getvar all to help you but it seems that you made it harder now because you installed a wrong firmware. If it is S-Off, then it is easy to fix.

First - remove all serial & imei no. from your above post.
As I said, it is not easy to fix this with S-On device. What you can try is to install the latest AT&T 6.20.502.5 firmware first then run 6.20.502.5 RUU
Read this for the firmware and how-to : http://forum.xda-developers.com/showpost.php?p=66886759&postcount=23
You can get the RUU here : http://www.htc.com/us/support/htc-one-m8-att/news/

so your saying, install the ruu, update the firmware, then re install viper?
Can't I just update the firmware like I did before? It was S-On before I updated the firmware
The ruu won't install. it says needs more then 30% battery, yet it is fully charged

No .. I don't say that ... read again ...
Flash firmware.zip first then RUU ...
or install ROM first, don't reboot the system, but reboot to bootloader, relock bootloader then flash firmware.zip
As you already flashed a wrong firmware, as I said this may work and may not work but the only way that you can try to fix the wrong firmware installed.

ok .. now that I understand what you are saying. because you had the RUU .exe and also were explaining how to update the firmware at the same time while the firmware was burried a couple of levels of posts, I didn't understand what you were saying.
so it looks like the firmware updated successfully

I unlocked the firmware through the htc website with the Unlock_code.bin
because fastbook oem unlock didn't work.
had to reinstall twrp and that worked after reinstall. although lots of mounting file system errors. with /Data I don't know if that's normal.
seems to be fixed after formatting
Now I will try installing a rom

Now you got it.
And yes, after changing from GPE to Sense GSM (AT&T) firmware, you need to reinstall TWRP (the latest 3.0.2-0) and you MUST format data partition, in TWRP - select WIPE, Format Data - yes ... because GPE & Sense data partition is of different size.
Please where can i get compatible firmware for my htc one m8s with S.O 1.12.1405.6 . I have been on this over 3 weeks now but all no avail.
Hey guys
like described in the thread title, i need a little help here, i got a HTC one M8, thats stock in fastboot.
it will not bootup to anything else than fastboot and RUU. no custom recovery is working or any rom.
i have read multiple threads by now and look 3 days and i can't find the right RUU for the device at all.
If someone could point me in the right direction here i would be grateful

for the steps to do here:
since device is S-ON, i need to relock the bootloader with fastboot oem lock
using the HTC_fastboot.exe with command prompt to get the device into RUU mode and after that flashing the correct RUU for it, after renaming the .zip itself to RUU.zip, right?
or is there any other way to get the device back to stock or at least a custom recovery / root whatever to set the device S-OFF?
i know the topic was here multiple times, but since device isn't mine and i really don't know what exactly was done before with it, i need a helping hand here.
any fitting android version, 5.0.1 or 6.0 would be fine, since the device will get root and later on S-OFF and a custom recovery and another nougat based android version.
as long as i can boot up with root, i would appreciate every help here.
Cheers

1. This device is not M8 but M8s.
2. There is no way to S-Off this device currently. Not supported by Sunshine.
3. There is no Nougat rom for M8s, only Marshmallow as current latest.
4. You shouldn't relock bootloader before you have a correct RUU in hand.
5. I know a lower RUU version is available for free but won't work on your device due to S-On
6. No same version but higher version 2.11.161.1 is available but will cost money
7. If you can unlock bootloader then you can restore 1.11.161.10 twrp backup and then OTA to current version 1.21.161.1 and OTA up to the latest.
https://www.androidfilehost.com/?fid=24591000424942287
8. Here is section for M8s - https://forum.xda-developers.com/htc-one-m8/one-m8s-general
So I've been trying to upgrade a T-Mobile HTC One M8 that was stuck on Lollipop to the official Marshmallow update RUU. However, when I downloaded the RUU and attempted to run it to flash the phone, it gave me Error 155, despite the fact that I had relocked the bootloader before I ran the RUU. No matter how many times I redownloaded the RUU.exe and ran it, it always gave me an Error 155. At this point, I do not know what is causing this to happen and I don't really know how to solve this issue. Help is appreciated!
I should add that the M8 was rooted and had TWRP installed before I tried running the RUU.

There's a weird glitch with US versions that you have to flash the firmware before you run any 6.xx RUUs
Download this
Put it in your fastboot folder and:
fastboot oem rebootRUU
fastboot flash zip fw_6.20.531.5.zip
then run the RUU again

Thanks for your help! I was able to run the RUU after flashing the firmware. The M8 is now running smoothy with Android Marshmallow and Sense 7!
Hi all,
I have an old HTC one m8 which was working fine when I stored it away last year. Today I tried to turn it on and found myself looking at safe mode menu with the heading
"Software status: Modified"
LOCKED
Security Warning
Now I have been going through the form for the last couple of hours trying different things but they dont seem to work.
e.g) I got a ver 4.20 RUU for my phone mentioned in this link
https://forum.xda-developers.com/htc-one-m8/help/finding-ruu-t3283633
but that does not work because my phone currently is on OS-6.13 and apparently I can not downgrade to OS-4 while my phone is S-ON. (I get ERROR 159 IMAGE ERROR)
So i tried to make it S-OFF. Unfortunately from what I have read they only way to do that is through the adb tool which does not work in the fastboot mode I am currently stuck on (fastboot commands work fine from my PC). So I can't downgrade to the only RUU I have found for my modelid and cid. I have no idea how to proceed now.

Any ideas?

Correct. Downgrading is not allowed with s-on.

There is no (current) valid method to s-off using adb. If you are talking about firewater, that method has not worked since 2014, and nothing you do will make it work.
The valid current method to s-off is with sunshine app ($25 US) but also requires a working OS.
You also do not need s-off to get the phone working again. Since a Marshmallow version RUU for your CID/MID is not available, you can restore the stock TWRP backup from the collection in the link below: https://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
Unlock bootloader using HTCDev.com, install custom recovery TWRP, then restore the TWRP backup 6.13.206.5 using the instruction in the link above.
