ADB, Recovery and some issues

Hello XDA-Community,
I have an HTC One M8 (M8_UL) with the following details:
Software Status: Modified
*** UNLOCKED ***
And I have Cyanogenmod installed (latest nightly build 12.1-20151118-NIGHTLY-m8 Android 5.1.1) and TWRP 2.8.7.0
Now my GPS is not working since a while now (I can't really tell if it has even started when I moved to CM or if it happened afterwards).But GPS Status never gives me a single satellite. I have read in another topic here in the board, that getting back to Sense Stock could help. Then back to CM and everything could be fine.
But here my questions start:
1) What exactly does this S-ON mean?
2) So how do I know which firmware/recovery/system (I figured out that there is some difference between all this and that now my TWRP 2.8.7.0 obviously is my Recovery Tool installed at the moment.
3) What is RUU and OTA ? As I understood its like a Operating System Update out of windows? I once downloaded a version but it always claims my battery would not be full so it would not let me update/upgrade/recover?
4) Why is my version-main info empty? (see below)
Sorry for all these questions and thanks in advance for your help

1) What exactly does this S-ON mean?
S-on/s-off is a HTC specific security flag. S-off means "security off" and in the past meant that all security checks are bypassed. On the M8, its a little more complicated than that, some things are bypassed, some are not. But it allows you to do things like flashing modified hboots, radios, unsigned RUUs and downgrade firmware. S-off is kind of a "back door" that HTC leaves for itself. But when exploited by users, such as the devs here at XDA, is handy for some pretty useful things. S-on is the "stock" condition, and means you don't have the ability to do these things. In order to get s-off, you need to use the sunshine method, which costs $25. But s-off is not required to flash ROMs, root, or return to stock.
2) So how do I know which firmware/recovery/system (I figured out that there is some difference between all this and that now my TWRP 2.8.7.0 obviously is my Recovery Tool installed at the moment.
Firmware number is indicated by main version in getvar output, or by the "OS" number on the bootloader screen.
If you want to go back to stock recovery, you will want the stock recovery file that matches your firmware number. But for what you describe, I don't think you need or want to flash stock recovery.
System is the ROM version number, and again if you are returning to stock, you should find the nandroid that has the same number as your firmware.
Don't confuse any of the above with the software number in the phone's settings (common mistake). That number is related to the current ROM. So if you flash a custom ROM, that number just corresponds to the custom ROM, not the firmware or stock ROM number.
3) What is RUU and OTA ? As I understood its like a Operating System Update out of windows? I once downloaded a version but it always claims my battery would not be full so it would not let me update/upgrade/recover?
RUU and OTA are related, but two very different things:
RUU = ROM update utility. Its a Windows executable, normally an official HTC tool that will completely re-image your phone to stock, every single partition, and will also wipe your phone. The CID and MID of your phone need to match what the RUU is intended for. Does not require stock ROM or stock recovery to run, but has to be same or greater version number than main version (or hboot) on the phone - meaning you can't "downgrade" (unless you have s-off). Relocking the bootloader is required to RUU (again, unless you have s-off).
OTA = over the air. Its an incremental OS update, sent out by HTC. It normally requires the software number directly proceeding it, meaning you need to install them in sequence, and can't skip any. And may not be a complete image, but simply a "patch". It also requires stock recovery to be present, as well as the stock ROM. No need to relock bootloader to OTA (unlike RUU). Also, OTA will not typically wipe the phone (but you should backup before OTA to be safe, as it does sometimes wipe data).
4) Why is my version-main info empty?
Common issue. This is usually because an outdated 2.7 version of TWRP was installed at some point, wiping out the main version info (known TWRP bug).
On the bootloader screen, does it read a number after "OS" in green letter?

So if I don't know my firmware/OS - number? how do I choose a proper nandroid backup? and does a nandroid backup does return my phone to sense ROM?

I'm not a CM user on this device, so I'm not too familiar with the issue.

I believe your firmware is 4.16.401.x (possibly "8" where the "x" is), based on your CID, and hboot and radio numbers indicating you are on Lollipop firmware.
Are you sure its a nandroid that is being discussed in the "fix" and not RUU to stock? If you direct me to the thread/post that discusses the fix, maybe I can take a look and see if I can figure anything out.
But yes, a stock nandroid for 4.16.401 will return you to the Sense ROM.

On http://forum.xda-developers.com/showthread.php?t=2701376 I can not find a nandroid stock backup that is working. The link to 4.16.401.10 - TWRP Thanks to sneakyghost is not working anymore on mega :/
How do I create a nandroid backup myself (after hopefully I get fixed everything)?

I could replace my Cyanogenmod with a stock nandroid backup of htc sense. but it did not fix the GPS problem. Still not a single satellite to receive :/
Even erase modemst1 and erase modemst2 did not fix anything :/
Anyone has a hint what to do?

M8 No OS After Flash

Hi,
Having issues trying to put SuperSU on my M8. Heres what I've done:
- Unlocked bootloader
- Fastbooted TWRP on the phone
- Tried Flashing the ROM, says No OS installed. Rebooting stops at Android screen
- Tried downloading RUU and going back to stock, however the RUU tells me that there's an error and it can't continue.
- Tried switching between TWRP and CWM.
- Tried sideloading from my pc with a few different versions of SuperSU
Nothing seems to work.
Can anyone point me in the right direction?
Any help will be greatly appreciated.
If there's any more information you would like me to provide, just let me know.
Thanks Again,
Nick

Having issues trying to put SuperSU on my M8. Are you trying to root the stock ROM, or flash a custom ROM? Because they are 2 different things, with different approaches. And your steps described below contradict each other on this matter..
Heres what I've done:
- Unlocked bootloader
- Fastbooted TWRP on the phone What version TWRP?
- Tried Flashing the ROM, says No OS installed. Rebooting stops at Android screen Which ROM exactly? Did you try another ROM? Did the ROM install properly (any error messages in TWRP when you flashed?
- Tried downloading RUU and going back to stock, however the RUU tells me that there's an error and it can't continue. What RUU (exact file name)? What was the error message and error number? These are important, as they tell you why the RUU failed.
- Tried switching between TWRP and CWM. Not recommended. CWM hasn't been updated in a long time, and can cause some problems in itself.
- Tried sideloading from my pc with a few different versions of SuperSU If you have no OS, flashing SuperSU isn't going to help matters.

Additonally, do fastboot getvar all, so we can see more info about the phone. Delete IMEI and serial number before posting.

Are you trying to root the stock ROM, or flash a custom ROM?
Originally I tried to put SuperSU2.37 on there, that didn't work, so I tried SuperSU2.77, which failed. I then tried to RUU to stock, which I'm having issues with also.
- What version TWRP?
3.0.2-0
- Any error messages in TWRP when you flashed?
It doesn't show any errors. After it's finished it says No OS Installed, are you sure you want to reboot?
- What RUU (exact file name)?
RUU_M8_UL_M60_SENSE70_MR_BrightstarUS_WWE_6.12.1540.4.exe

SuperSU version 2.37 is really old. Not sure how you even came about it (old toolkit maybe?), that version probably wouldn't work on Lollipop, much less your current Marshmallow firmware.
SuperSU 2.77 should be okay, its current and updated for MM. I might suggest the latest "STABLE" version, which is 2.76 from here. But honestly, they are all pretty stable from what I've seen, and it probably wouldn't make a huge difference wither way (the version 2.77 should be ok). And it seems like the main problem is that we need to solve the "No OS" issue before proceeding.

My guess, is that you did something to delete the OS, that maybe you missed when listing the steps you did. Since, I can't see how OS could be wiped/missing with what you indicated. At least up until you tried RUU, since if you relocked the bootloader to RUU (which is a requirement unless you have s-off), that wipes the OS (so maybe you just have the order of steps you tried, mixed up?).

That RUU isn't for your version. Maybe the "WWE" in the file name has you confused, but its actually for the US Developer's Edition. What you need would have version number with "401" instead of "1540", but you would only know that from experience or reading it somewhere on the forums.
You should be able to use the following RUU (zip format, not exe - so follow the instructions to flash): http://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
Alternately, restore the stock TWRP backup 6.12.401.4 using the file and instructions here: http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
Not sure whether your bootloader is currently relocked or unlocked, as you haven't indicated, either way. It needs to be relocked to RUU, or alternately it needs to be unlocked to do the TWRP stock backup method.

Sprint M8 Stock Roms

Hi, I made this post in the Sprint section a few days ago, but figured I'd post here as well to see if maybe this section has more traffic. If that's not allowed, I apologize in advance.
https://forum.xda-developers.com/sprint-htc-one-m8/help/stock-roms-t3669676
Basically, I'm looking for a stock rom for Sprint that would work with 1.54.651.8 firmware. All the links I can find on the forums seem to be dead.
Alternatively, a nandroid backup or way to extract the rom from the 1.54.651.8 RUU I do have (but won't successfully flash for whatever reason)
Any help would be appreciated. Thanks!

A custom ROM would need to support the Sprint M8, and be based on 4.4.2. Most any newer (newer than KitKat) ROMs will suffer major incompatibility with your ancient firmware, including extreme long boot time or no boot, and broken WiFi.
Suggest stocking with updating the firmware. Is the device s-on or s-off?
Problems with the RUU while "sending" are usually on the PC side. Try to re-install HTC drivers, try another USB port (USB 2.0 works best), and try another cable. Or even try another PC if possible.

Yeah I was able to find one custom 4.4.4 ROM (It was labelled 4.4.2, but it works so I guess it's close enough). There are just a few issues with it and I've always been more of a stock person anyway so I'd rather use a stock rom if I have the option.
As far as updating firmware, I am S-ON - I only originally rooted for a wifi hotspot app, so I didn't have a need to go S-OFF.
I guess it wouldn't hurt to give the RUUs a shot on a different computer. I'll just have to talk a friend into letting me install the drivers and giving it a go. One thing I'm not sure about - is it safe to go straight to the lastest RUU on HTC's site? I was willing to try it back when I had no rom at all, but now that I have a custom rom that mostly works, I'd rather not totally crap the bed.

You can "skip" RUUs, and go the latest. However, you may (probably) need to update to the Marshmallow firmware anyway, before you can RUU. There is a strange limitation on most US version M8, where the RUU will fail with Error 155, if you try to go to Marshmallow from any former version (be it Kitkat or Lollipop) without first updating the firmware.
So the steps would be:
1) Relock bootloader
2) Flash to Marshmallow signed firmware (Sprint), in fastbootRUU mode
3) RUU to Marshmallow
4) Unlock bootloader again
5) Flash TWRP, root, and do whatever mods you want
Seeing as RUU will also wipe the phone. All this might be more than you want to do, if you are fairly happy with the phone as it is.

I don't so much mind the wipe, but I am a bit nervous about updating the firmware since that sounds like it could leave me in limbo if the RUU still didn't want to work for whatever reason. I guess I'll search around for where I can get that firmware and the procedure of how to do it and see how comfortable I feel with it in case I go that route.
If I knew for sure that it would all go through, I'd be fine with the reset. But that seems to take the attractive part of the RUU away in that it's no longer an "all in one" or one step process. (Not counting unlocking/relocking the bootloader since that's a quick and easy thing).

The firmware is posted in the same thread as the RUUs. And instructions on how to flash, as well.

You can also opt for the Lollipop RUU (does not require flashing the firmware first). While not the latest, it's obviously more updated than what you presently have. And most of the current MM ROMs should work with LP firmware. There isn't much difference in the firmware it seems, for LP versus MM. Much different from KK to LP, which causes the problems I mentioned earlier (if you try to run KK firmware with LP or MM ROMs).
For maximum compatibility, matching the firmware is usually best. But I was running LP firmware with MM ROMs for a while (was simply to lazy to flash the MM firmware or RUU).

Ok so it sounds like the easiest option for me at this point is to grab a Lollipop RUU and try to flash it from a new computer with a fresh install of all the drivers. That way, at least if it fails to recognize my phone like the newest one did, I'll still be where I currently am with the stock (though outdated) firmware and custom rom.
Otherwise, I'll keep my fingers crossed that someone stumbles across this thread that has a meticulous archive of all old stock Sprint roms
Thanks so much for all your help and answering my questions so quickly. Much appreciated.

Hi

after jail break it's supported Indian GSM sims there after only outgoing calls are working incoming calls are not working.

"Jail break" is a term specific to only iPhones. There is not such thing as "jail break" on an Android device. I assume you mean s-off, or some other mod? I can only guess, if you don't use the specific and proper terminology.

All in one Toolkit is obsolete, you shouldn't be using it. It contains a very old version of TWRP which will cause problems for many folks.
System partition is the OS/ROM. Should be obvious, that wiping the system partition results in no OS. Can't boot to an OS that isn't there any more. If you didn't know what the result would be from wiping a partition, you should be touching it in the first place!!!! Those options are listed under "Advanced" for a reason. If you aren't an advanced user, don't mess with them, unless you are following directions form an experienced user, or know what the result is going to be.

Not enough info to know why the RUU failed. You linked a post with multiple RUUs, so we don't know which one you tried. We also don't know your current phone configuration.
Which version number RUU did you try? For HK version, you typically will need to flash the one that contains the digits "654". The RUU with digits "651" is for non-HK Sprint version. Assuming CID/MID has not been modified (which we don't know, if you don't provide more info).
Post specific info about your phone. Do fastboot getvar all, and post the results (delete IMEI and serial number before posting).
If the phone is s-on, you need to lock it in order to RUU. I don't know if you are s-on of s--off.
You can't run a lower number (downgrade) RUU unless you have s-off. Again, I don't know what version number RUU you tried, your current version number on the phone, or whether you are s-on or s-off.

Hi Sir,
Thank you for replying. Sim Unlocked from mobile store. actually I also don't know witch method they are using to unlock. After unlocking network signals showing in GSM mode. When I am changing to LTE mode again signals disappeared. In GSM mode incoming calls are not working. SMS both incoming and outgoing working fine.

LTE is difficult (maybe impossible) to get working in cases where the device is not intended for your region/carrier (which I assume is the case, that you are not located in US, on the Sprint carrier). GSM should work (as you indicated) as well as 3G (HSPA) provided that your carrier uses a band(s) supported by the Sprint version M8
I tried to change CID and s-off but it's not working. I don't know what that means "it's not working". Most folks who say they have trouble with getting s-off, are trying the hopeless waste of time, which is trying to usethe long obsolete "free" s-off method of firewater. It's never going to work.
Also, you should also be careful here, when changing CID. Only use a Sprint CID, or SuperCID with a Sprint firmware/RUU. Trying to use any other firmware or RUU will result in a radio brick (possibly permanent).
TWRP I used version v2.7.0.2 these recovery installed from all in one twrp (sprint). when i come back in to bootloader it will asking No OS installed are you sure you wish to reboot? That version is too old (over 4 years) and you should have used current TWRP. This was probably caused by using the toolkit (which I mentioned is not advised anymore). Old versions of TWRP was not compatible with Sprint M8 (it had it's own "CDMA" version TWRP) and it probably caused the wrong partition to be overwritten.
What was I do is
First Re-locked bootloader using with all in one and rename firmware as 0P6BIMG.ZIP then flash from SD Card Installed Successfully. Bootloader also showing OS version 6.20.654.3 Try flashing firmware again, the number should show up in getvar all (below) under "version-main". Flashing firmware twice is usually a good idea.
Next using exe file "RUU_M8_WHL_M60_SENSE70_SPCS_MR_Sprint_WWE_Harman_6.20.654.3.exe" everything going well when the process bar reaching to 100% then it's showing error 155. I Checked the error guide provide by exe file there Unsupported RUU please try again with supported RUU.
Error 155 is common, if flashing a US Marshmallow RUU, without being on the matching firmware. Flashing firmware again, as indicated above, may solve it.
Next using with ZIP file "0P6BIMG_Sprint_HTC_One_M8_Harman_6.20.654.3_RUU.zip" flash from SD Card it will showing not enough memory but internal is full empty.

Which version is the M8 I bought ? Tampered/compromised phone ?

Hello, sorry for the probably completely noob question that might have already been answered but I searched for this answer and dinn't find anything really relevant.
I'd like to check the version of the unit I received so I can install a proper ROM without killing the phone as I'm aware certain versions of the M8 (GSM/CDMA) might get into troubles if wrong roms are used.
So I bought this phone from a chinese reseller. Phone is obviously refurbished (phone was rooted "out of the box" with all bloatware removed). There is a sticker on the back of the phone with 3 barcode (P/N, S/N amnd IMEI). What's strange is IMEI is similar on sticker and "about phone" but S/N doesn't match, as if it had been tampered/manually modified... So, definitely, the motherboard or the case had been replaced and I couldn't rely on the model number wirtten on the back of the phone.
First thing I tried was using the IMEI to check version but it matches an HTC Desire 820, I wasn't aware you could modify IMEI or dupe. Anyway, I moved on to the next step, which was going into bootloader. Bootloader says CID-1111111, which is, from my understanding, a way of making the phone open to any roms, from any country. Ok, one more info that doesn't help.
So I used the fastboot getvar all and it gave me this :
Code:
(bootloader) version: 0.5
(bootloader) version-bootloader: 3.19.0.0000
(bootloader) version-baseband: 1.24.21331147A1.09G

(bootloader) commitno-bootloader: 3aa067db
(bootloader) hbootpreupdate: 11
(bootloader) gencheckpt: 0
I googled "0P6B6****" (it comes with the ****, I didn't replaced any digits, only hidden IMEI and S/N) and it didn't gave me any solid information. Since phone was rooted and seemingly heavily tampered, I went back to stock and possibly get OTA to get Marshmallow (current os is 4.18.708.12) but there's no more updates so I'm "stuck" with 5.0.1. I thought the phone was initially a taiwanese version since it had the Snapdragon [email protected] but there's a lot of chinese bloatware.
So I can't update to M and therefore convert the phone to GPe or even use any custom roms (unless I missed something and I'm completely wrong). Can you help me trying to figure out what I received and if there's anything I can do with it or if I'm stuck with the stock rom.
Thank you.

Your device is GSM which is good if you're not on US CDMA carrier.
0P6B6**** is SuperMID, 11111111 is SuperCID.
Depends on what you want your device to be, I suggest to change SuperMID to actual MID of your intended region.
If EU, change it to 0P6B10000, leave SuperCID as it is now then install latest Marshmallow RUU. You also can try to install RUU with SuperMID and see whether it works or not. AFAIK it should work with SuperMID.

Thank you for your quick answer. Yes, I use it in Europe so it works fine with my carrier (even if LTE B20 is missing but it's ok). I'll do as you suggested. I'm glad I got a GSM-only phone, I thought I received a hybrid unit. Thank you again.

Ok, so I modifed MID 0P6B10000 and then tried to install latest Marshmallow RUU 6.12.401.4 via fastboot but phone is not booting up (stuck on HTC One logo). So i restored with my previous clean Nandroid backup. I'm back to 4.18.708.12 (phone is 100% working)
First question : bootloader tells me os is 6.12.401.4 while I'm actually running 4.18.708.12. Is it a problem or not ?
Second question : in order to have a working (eu) MM rom on my phone, I guess I'm supposed to flash the firmware to the latest right (which is something I haven't done in my previous attempt to flash MM) ? But which one am I supposed to grab ? 6.12.401.4 or 6.16.708.1 ? I'll use your guide to do it (https://forum.xda-developers.com/showpost.php?p=60218734&postcount=5). Can you confirm updating the firmware is mandatory before flashing stock MM rom when upgrading from Lollipop stock ? I can't install MM RUU, coming from LP, without flashing the fw first ?
Once firmware is updated, I can safely flash MM 6.12.401.4 ? I might as well flash to MM with TWRP and use one of your stock MM backup. Can it be done coming from my current LP rom version ?
Last question : let's say I flash the 6.12.401.4 firmware and keep the 4.18.708.12 LP rom, phone won't boot right ? Keep in mind I have a phone with a ModelID 0P6B10000 and a stock LP rom 4.18.708.12
I'm sorry for the noob questions and to bother you with these but I tried a lot of different things (and I don't want to go to fast and kill the phone) without any success, and since this is my first HTC phone, there are some novelties in the flashing process. And I recovered the phone several times so I might run out of luck next time.
Thank you again for your help.

Which RUU you tried ?
Try this - https://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
Your bootloader now 6.12.401.4, is it written as single not double in red ? If single then it is ok
Lollipop ROM can work when firmware is MM.
Most of the time you need to install MM firmware first to install MM RUU but the above linked RUU, you don't need to.
Since your firmware already updated to 6.12.401.4 you can restore 6.12.401.4 backup available in my backup thread to have stock ROM running or install any custom ROM that you like. You don't really need to make it stock MM rom first if your plan is to install custom rom. Only you need MM firmware installed, install latest TWRP 3.x then install rom
To your last question, when you have lollipop rom running and you flash only MM firmware, it won't boot as boot.img installed now is MM and the LP rom needs LP boot.img to boot

OS line is green and single so I'm good.
So if I'm understanding correctly, if OS in bootloader says 6.12.401.4, then it means firmware actually installed on phone is 6.12.401.4.
Now, when installing the RUU zip provided there (https://forum.xda-developers.com/showpost.php?p=64926626&postcount=6), the file is corrupt, on both links. File size is correct in Windows but when I open the archive (for example to add 11111111 in android-info.txt), it says archive is corrupt and file size of the different files in this archive are way too small.
I'm gonna try Nandroid backup.

Don't do thing that is not in the instructions. No where I wrote you need to add anything to the RUU zip. It's simple process, why need to make it harder ?
RUU zip is a htc signed zip. No windows archiver such as winzip, winrar, 7-zip and etc can properly open it and you're not supposed to open it.
Read the instruction again. No need to add 11111111 to the zip as there is no such thing as SuperRUU or SuperFirmware. 11111111 is for the device which means your M8 is SuperCID and you can install the zip regardless what your device CID is.

You are absolutely right about me doing unnecessary steps. That probably explain why I didn't manage to get it working. Anyway, I used twrp to restore one the MM Nandroid backup you provided in one of your post (+ recovery) and it went smoothly. I'm now on MM and phone is working fine. I'll see if it's worth flashing a custom rom if I can find one that fits my needs.
Thank you for your answers, it did help me quite a lot. Your guides (+ all the different files you provide) are excellent, as long as you follow the instructions and don't do unnecessary steps
Have a nice day/evening.

hi,
I also have a htc m8 with modelid: 0P6B6**** and sid=1111111 which I want to use in the UK, but mine is the dual sim version of the phone
I tried following the instructions at https://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
It seemed to be installing but after about 20mins it failed with the error - "(bootloader) shift signature_size for header checking...FAILED (remote: 32 header error)"
I then found another RUU which I think is the correct one but received the same error (0P6BIMG_M8_DUGL_M60_SENSE70_MR_HTC_Europe_6.16.401.1_Radio_1.24.30336021.13G_30.69.336021.00_F_release_465001_signed.zip)
btw - i tried changing the mid to 0P6B10000 but this also failed (i downloaded an app which runs in twrp to do it, is this the correct way?)

Finally you post your question in right section instead of ROM development thread.
I read all your questions before but I ignored them as they were posted in wrong section as I don't want to clutter ROM development thread with Off-Topics.
I don't think you can update your device directly to the latest Marshmallow as your current firmware is Lollipop. In order to do that you need to install Marshmallow firmware first then RUU but I don't see Marshmallow firmware is available anywhere except the RUU.
So my suggestion is install the Lollipop RUU then do OTA to Marshmallow. You may need to do 2 or 3 OTAs to reach that level.
1. No need to change anything to your MID yet. Let it be as it is now 0P6B6****
Only when the RUU fails to install due to MID error, then you need to change it to 0P6B64000 NOT 0P6B10000
https://forum.xda-developers.com/showthread.php?t=2708581
2. Download 0P6BIMG_M8_DUGL_L50_SENSE60_MR_HTC_Europe_4.30.401.15_Radio_1.24.30336021.13G_30.69.336021.00_F__signed.zip
from here - https://easy-firmware.com/home/browse/category/id/7825/
3. Install the RUU as instructed here - https://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
but use the above downloaded RUU
or you can rename it to 0P6BIMG.zip and place it on your microsd and boot to bootloader to install.
Make sure you don't rename it to 0P6BIMG.zip.zip

Hi,
Thanks for your reply - sorry if I posted in the wrong place etc. - I struggle as I can't get the xda search to work so find it difficult to find anything.
As you know I keep giving up on this but then end up trying again and spending all night messing about with it.....
I tried installing *0P6BIMG_M8_DUGL_L50_SENSE60_MR_HTC_Europe_4.30.401.15_Radio_1.24.30336021.13G_30.69.336021.00_F__signed.zip* but get the same error.
I am not sure if this includes the firmware or if that is separate to the RUU (as I have tried to install new firmwares so the installed one may well not be the correct one).
update: I have now installed the firmware to match (i.e. a 40mb zip file version 4.30.40 1.15) but still getting the error when i try to install the RUU
btw - I tried copying to the sd card but that gives error "device halted due to large image update fail"

I guess you need to change your MID 0P6B6**** to 0P6B64000
then try again the RUU.
I already gave you link on how to do it as in item #1

I changed the MID but then when I rebooted in to fastboot I was no longer able to connect via the fastboot command on my computer (just stayed in "waiting for device" although ADB still works ok).....
But I copied the RUU to the SD card and it installed ok
I am just doing a first boot in to android and will let you know how it goes
Thanks again for your help

The update applied ok and I booted in to the new version of android no problem
but still when I try to use fastboot it just stays in "waiting for device" on my computer (Linux) so I am now stuck as you need fastboot to be able to install twrp.
bootloader on the phone detects when I plug the pc in with "BOOTLOADER USB". This text is highlighted in red, I think this is normal?
"htc-fastboot devices" shows nothing
btw - I have tried it on another computer and is the same

First thing is why did you relock bootloader. I never say you need to that because your device is S-Off
I'm not familiar with linux, never see BOOTLOADER USB, only FASTBOOT USB. Do you have access to any windows PC ?
You don't really need to do fastboot oem get_identifier_token to unlock bootloader, what you need is only a flashable TWRP zip and use adb command to unlock bootloader. Later tonight when I'm home I'll upload the flashable TWRP zip and instructions on how to unlock it.
Mean time please advise the OS no. written on bootloader so I can write the same to TWRP zip.

Hi,
I had assumed it had re-locked the bootloader but later realised it was still S-off

My phone shows OS-4.30.401.15

On another subject, the GPS on this phone seems to be dead (it has never seen a single satellite), is this a known problem with these phones do you happen to know?
thanks

I thought you want to update to the latest so you can install LOS14 or LOS15 or any custom ROM later.
Once you successfully back on stock 4.30.401.15, you should check for OTA and install. I believe you will have 2 or 3 OTA to get to Marshmallow firmware.
Have you check for OTA & update ?
About GPS, maybe you have faulty gps cable in it. I don't have M8 dual SIM but no reason why it is not working unless it is hardware issue. I can't help when it comes to hardware.

I don't make mistake as I understand what you are trying to do. If you unlock bootloader and install twrp now, you're back to earlier problem.
To install LOS 14, you must have Marshmallow firmware installed. Now you're on stock 4.30.401.15. You don't need to do unlocking & install twrp yet. You need to do OTA until you get final OTA either 6.16.401.1 or 6.16.401.101 then only you proceed to unlock bootloader and install twrp and install LOS 14.
Forget about link to GPS matter for now as that require device teardown.
Most important now OTA. Without OTA it serves no purpose on what you're doing now and intend to do later.

ok - thanks, I think I now know what I need to do (how many times have I thought that in the last few days - lol)
I Just tried fastboot on a windows laptop and it works! (no idea what is going on there - but at least I can now use it again)
it now shows modelid = 0P6B640000
BTW-I think the universe has it in for me regarding this project as apart from wanting to use LineageOS, the main reason I bought a new phone is that my existing phones GPS stopped working.........

In case you're not sure what OTA I'm talking about, go to settings - about - software update - check here for OTA. When there is one, download and install. Again repeat the process until it says there is no update available.
Every time you install OTA, you OS no. on bootloader will change to current firmware. You need this until the OS no. is written as 6.16.401.1 or 6.16.401.101.
Then only you unlock bootloader and install latest twrp 3.x and install LOS 14

Need Help with HTC m8 Demo Unit *Stock Rom* - Wants to Flash Custom ROM

Hey everyone!
I just got HTC M8 from a friend, and figured out it is a demo unit. It comes with a demo app, which I am unable to get rid off. It was firstly rooted and mistakenly I removed the internal storage. After all the mayhem, researching for hours on this forum, I am finally able to get my device back running but still the demo app is there. I am unable to make any changes in developer options or through control center. I am new to all modding, HTC, Android and custom / stock roms.
I have few questions after reading a lot. After accidentally deleting the OS, and wiping internal memory - I was able to get it back, but now wants to run a custom ROM on it but not sure if I am able to do it with current status of my device.
Information about device:
HBoot: 3.16.000
S-ON
HTC__002
Unlocked Bootloader
TWRP installed (but throws error whenever I try flashing a zip file)
The question: Can I install a custom rom without getting S-OFF and if yes, which custom ROM can I use on my device? I understand there is some limitation to HBoot version, but I am unable to figure out how to update it to latest version. I would like to update my device from Android Kitkat to Marshmallow or some custom ROM which doesn't have a demo app.
P.S: A noob!
Update:
After reading lots of threads, I finally bought Sunshine license and activated S-OFF, now, I am with SuperCID 11111111 on my demo unit. Now, I want know about which Custom ROM I can run, and how can I update my Hboot to latest version?

You can use this ROM

Might help, if you tell us what error message TWRP gives you.
Hboot version is too old to flash most ROMs. Also, such an old hboot version, is not compatible with many TWRP versions (might be the reason zip won't flash in TWRP).
What TWRP version?
Do fastboot getvar all, and post the result (delete IMEI and serial number before posting).
I believe @ckpv5 knows some about how to get the demo versions working or modded. The demo versions pops up infrequently enough, I can't remember the exact details.

He says TWRP gives an error flashing zips. So how is he supposed to install that ROM?
Most likely, his Hboot version is too old to support that ROM.

Yes, Hboot version is too old. I had a long fight with getting it restored. I had to try every other TWRP version and suddenly TWRP 2.8.0.0 worked for me!

Problem I face:
- Current TWRP is old, I am unable to make most out of it. (v2.8.0.0)
- Hboot is like hanging in stone age, I need to update it - but I have a demo unit (it comes with annoying demo app!)
- I want to run Custom ROM or at least a newer Android version.

Might help, if you tell us what error message TWRP gives you.
Hboot version is too old to flash most ROMs. Also, such an old hboot version, is not compatible with many TWRP versions (might be the reason zip won't flash in TWRP).
What TWRP version?
Do fastboot getvar all, and post the result (delete IMEI and serial number before posting).
I believe @ckpv5 knows some about how to get the demo versions working or modded. The demo versions pops up infrequently enough, I can't remember the exact details.

He says TWRP gives an error flashing zips. So how is he supposed to install that ROM?
Most likely, his Hboot version is too old to support that ROM.

You should be able to disable the demo app, using the "alternative method" indicated in the following post: https://forum.xda-developers.com/showpost.php?p=59735868&postcount=10
You can update to a newer version using the RUU and instructions on the following post. You will need to relock the bootloader in order to RUU: https://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
Be aware that RUU will wipe all data on the phone! Again, you will need to disable the demo app if you intend to stay on the Marshmallow "stock" ROM.
Updating to newer version (Marshmallow) by RUU, will also update the hboot, and other firmware (radio, WiFi, etc.). So after that you should be able to use the current version TWRP (3.1) and the current custom ROMs. Again, I'm not 100% knowledgeable on the demo model. But I don't see how the demo version CID (which is what triggers the demo app) would prevent you from doing the above. Especially if you disable the demo app, or flash a custom ROM (non-Sense) that doesn't have the demo app to begin with.

Thanks @redpoint73 for the help. Here is an update:
I finally able to get rid of demo app using SuperCID - means, now I have S-OFF device. I used Sunshine apk. Now I would like to update my device to latest Android (Marshmallow) - so should I follow the instructions on the thread you pointed me or is there something else I can try instead of locking the bootloader again?

Meanwhile, I tried following the details on thread and got myself stuck on error:
FAILED (remote: 32 header error)
Whenever I try to flash the RUU, it gives this error!

1. No need to relock bootloader as you already S-Off your device
2. You got error because you don't use htc_fastboot as in the instructions.

Lots of love man! I finally got it. It worked like a charm through HTC_fastboot.exe. I was on macOS earlier and tried flashing ruu.zip through it, but after your message. I tried on Windows with HTC fastboot and wow!
I did a small mess and eventually relocked my bootloader! No issues with that, I can re-unlock it!
Thanks @ckpv5 for the final tip, and lots of love for @redpoint73 for pointing me at right direction!

Honest mistake. Relocking the bootloader is mandatory to run an RUU with s-on. So it's easy to miss the fact that the requirement (to relock the bootloader to RUU) is bypassed with s-off.
As you said, you can always unlock the bootloader again, if you want to install custom recovery, root, flash custom ROM, etc. Alternately, if you want to stay stock with no root, you can just leave it relocked.

You're very welcome. I wasn't sure if you wanted to pay for sunshine, so that is why I was suggesting some possible solutions with s-on. But glad to have pointed you in the right direction, regardless.

That is a very open-ended and subjective question. It's completely up to your preference, if you want to do any more mods. You can try custom ROMs, root, custom kernels, and much more. There really isn't much limit on what you can try.
