Hi,
I've recently been exploring this forum and finally bit the bullet this evening and decided to try and de-brand my EE branded M8.
Steps I took were:
1) Used Sunshine to S-Off
2) Installed TWRP
3) Changed my SID from ORANG001 to HTC__001
3) Installed SuperUser
4) Downloaded the TWRP Nandroid for 1.54.401.5 - TWRP from http://forum.xda-developers.com/show....php?t=2701376
5) Used TWRP to restore the Nandroid and confirmed the software version was now 1.54.401.5
I have a few questions:
A) After the install the apps I had installed (but not the EE bloatware) , my unlock pattern, contacts and wallpapers were all still visibile - is this normal? I had assumed the Nandroid backup would act like a factory reset.
B) Is it safe to perform a factory reset, or do I need to somehow install a new image for it to restore from? I mean going through Settings -> Backup and Restore rather than anything TWRP based. Ideally having downgranded the software I'd like a "clean slate" - but I'm worried it will try and install a newer version and fail
C) Is it safe to perform an OTA update (this was one of my reasons for debranding)? Anything else I need to do? (e.g. put stock recovery back on?)
D) Anything else I should be aware of? Any danger to leaving S-OFF and the bootloader unlocked? TWRP as the Recovery image?
Thanks
Hmm, even more strange, it seems my phone is confused about which software version is installed.
If I go to Settings -> Software Information -> Software Number = 1.54.401.5
But using fastboot to dump the variables I see:
(bootloader) version-bootloader: 3.16.0.0000
(bootloader) version-baseband: 1.17.2133156.UA20G
(bootloader) version-cpld: None

How does the Main Version not match the version I see through settings?
Does this explain why I can't install the OTA update (trying to use OTA simply gets stuck on Checking for Update)
Any ideas?

From what u told me in PM ur missing your correct firmware version (thats why the verion-main is different to ur nand and yes thats why ur OTA is failing
Check ur PM mate i have included instructions that should sort things
There are risks associated with staying S-off and BL unlocked. Just as taking control of the administrator account of a computer involves added responsibility and risk, so too does S-off and running with an unlocked bootloader.
1) It might be possible for a malicious app to seriously screw with your phone. If Sunshine can temp-root, so can other apps. With S-off, there is no protection from such things. Just as S-off allows you to truly own your phone, a clever, malicious hacker can also pwn your phone. You have to be vigilant, only install apps you trust, and keep an eye on things.
2) If your phone is stolen, all of the protective mechanisms have been disabled. Unlocking the boot loader normally wipes the phone, so the next "owner" can't get your data by simply installing a new OS. With S-off, you can completely bypass that. I consider this fairly esoteric because most phone thieves just want to sell the phone to someone else before the EMEI gets reported stolen. If they are even halfway clever, they might try to factory wipe it, but I doubt most of them are even that bright.
However, on the flip side, you also have the ability to fix and change things completely. You are the system administrator, not your carrier.
Just an update to let you know I did flash the firmware as suggested in exocetdj's PM back to stock and have since had two OTA updates install successfully. Since restoring to stock recovery and then performing a factory reset (via the HTC method, I did this before seeing I could do it via TWRP) I've successfully OTA updated like this:
1.54.401.5 -> 1.54.401.10 -> 2.22.401.5
I've decided to remain bootloader unlocked and S-OFF for the time being, in case I decide to play about some more.
Thanks to everyone for their help - I'm very pleased with my debranded M8!

If the nandroid does not include the data partition (and the stock ones posted to the collection presumably do not), it won't overwrite that partition on restore.

All factory reset does is wipe the user data partition. Reset in itself does not affect the ROM in any way.
I want to debrand as well but am totally noob to all this. As a result of what you did, are you now rooted or unrooted?

I am unrooted but this is by choice. I'm still s-off though should I decide to root again in future! I was a total noob a week ago but reading lots of guides and asking my questions here I've learned a lot.
Good luck!

I would like to follow your sequence in post #1 but I'm assuming that were additional steps that you had to do that you got via PM to get it truly WWE. Can you summarise the steps I'll need to do to debrand my O2 M8? I'd want to stay unrooted as well.
Also, the link in step #4 doesn't work. How did you know which version of Nandroid you needed? Thanks so much in advance

If you want to go International then you need one of the International backups. WWE English is x.xx.401.x which is why he went with 1.54.401.5

Thanks for your help. I've taken the plunge and washed my phone of O2. Phew!
Just a comment, I think if you've installed SuperUser, it means you're rooted? I avoided that route...
I was but I've since removed it. Congratulations on you're debranding!
Forget this sorted it all out, now running SRom ported lollipop with sense 7 from the M9. Hboot no red text and faux locked/original/son. Super CID.
For the record, it's always a firmware/dalvic cache problem (98%)
Hi Guys so Im rooted running Android Revoluton HD ROMs on an international O2 phone S-on
I thought I would wipe the entire phone, bleach it like a PC and reinstall.
Not a problem except various elements dont work.
I installed Stock ROM (I think KitKat)
I installed ARHD 22. (Kit Kat) everything worked
I installed ARHD 34.(Jellybean Sense 6) no wifi
I installed ARDH 40.(Jellybean Sense 7) no HTC TV
I installed ARHD 41.(Jellybean Sense7) no images in Blinkfeed?
I know its probably because I wiped the misc folder but up until I did a clean wipe I could use all of these roms without a glitch.
So is it firmware?
What do I need to put back on my phone for them all to work
I am S-on at the moment and I know that isnt whats stopping these roms working.
Any suggestions?

It's firmware. You most probably have kitkat firmware and lolipop based roms will mess up your wifi and stuff. Take an ota or stay on kitkat.
Thanks will try
Do I just flash the zip file?
Im sure I probs do

If you are S-ON don't flash firmware. Just don't. You can flash rom zips, recoveries, kernels. You can write on these partitions with s-on: recovery, boot, system and data.
I've just used Sunshine to get S-off, what a joy to use!
So now I can just flash them right?
I've got my cid number matched it up with the ota and bingo?
Right?

well im come from HTC One M7, and as long as the M8 is pretty much the same, you dont need s-off to flash the same firmware which your already on, or the next one step up, after all, this is exactly what an OTA does for you.
However, now your s-off anyway, you canflash any RUU or firmware you like, just make sure cid and mid match first. :good:
EDIT: there ia also no need to lock or re-lock the bootloader to flash anything now that your S-off, leave it unlocked all the time for everything, its a common problem on the M7 forums at the moment, people who are s-off or even s-on, locking bootloaders with custom rom's or recovery's on thier phones.
Thanks, so with the ota there are two for O2 my cid is O2___001 am I right that I can take the 001 OR the 002?

in all honesty, I would of thought the CID 001 and 002 were in the same ota, have you checked the android-info.txt file within the OTA itself, its just a zip file.
possible to post your fastboot getvar all without imei and serial number please, also a link to the OTA's your downloading would be good.
Well I've just tried to flash both....I enter recovery instal zip right?
It's giving me an error.
Will tell you that info in a minute when I get on my pc

personnaly, if your just trying to get to Lollipop, I would change my CID to HTC__001 (thats 2 underscores, CID is always 8 digits)
Change MID if required.
and then flash the WWE International Lollipop full RUU, piece of cake. http://forum.xda-developers.com/htc-one-m8/general/htc-one-m8-european-signed-ruu-0p6bimg-t2911563
But if the original isn't flashing what hope have I got with an HTC one. It's interesting to know though that I can change it.

Flashing an OTA manually is a different kettle of fish, its just an OTA not a full RUU, and you would still have to be full stock in order for it to succeed.
however, if you just require the firmware in order to use a custom LP rom, then just pull the firmware.zip out of the OTA and flash it.
you would then have to put a custom recovery back on your phone, copy a rom to your sdcard, and flash it from within TWRP recovery.
And im trying to flash O2 OTA

you already have the latest firmware on your phone !!!
I installed ARHD 41.( Sense7) no images in Blinkfeed? ------ pulled from your first post, this is a common problem, if you mean its face ache, there is a fix for it on playstore.
OK is tere an RUU for O2 uk?
So im extracting the firmware at the mo, then I will flash it then I will try and install ARHD 41....
Im right that the O2___002 is an upgraded version of the 001 and its what I need right?
Otherwise im just replacing like for like.

nope O2___002 is a different cid, you need to use the 001 files, however, its the same as you already have on your phone.
CID is just carrier ID, so O2___001 will be something like O2 UK and 002 might be something like O2 france, no difference in files, just different regions.

Make sure of a couple of things when flashing a custom ROM, check for problems other are having with it, by reading some of the later posts is what I always do, just a few pages, also and this is a must, read the OP's flashing instructions, so many people bypass this step, the most important step is to make sure your using the dev's recommended custom recovery for flashing.
I always full wipe before flashing anything, so in TWRP first factory reset, and then goto wipe - advanced - select everything except your internal storage and SDcard, and then always reboot back into recovery after the wipes before flashing the rom, it will nag you and say you have no OS installed, ignore it and Do Not Intall to SuperSU, the custom rom flash will do that for you.
During the rom installation, again I always select full wipe when given the option, you then know you have a clean slate to build the rom on.

Your firmware is already current, and should work with latest ARHD. Blinkfeed not showing image is a known issue reported by others.
No need to mess with RUUs or firmware zips.
Hey there.
I'm fairly new-ish to the Android modification scene. I've had android phones for a while but only recently started rooting etc one my One M8. I've got the Bootloader Unlocked with S-Off and am also on just the stock rom (or I was as I'm in the middle of attempting to get custom roms. :L). My custom recovery is TWRP 2.8.7.0, the latest and the roms I have been trying to install so far are the latest SkyDragon v10 Sense 7 and ViperOne 4.6.0 roms.
In TWRP, when doing this, it will go through the custom installation setup stuff and afterwards it will go into a never ending bootloop for around an hour before I decide to hold volume up and power to switch it off.
Now, before I do the initial installation of the rom, I have wiped data, system, cache and the Dalvik. Regardless, it still causes a boot loop. I have switched the phone off and waited 30 seconds. Still a bootloop. I have gone back into recovery and re-wiped the cache and dalvik and still get this bootloop.
Another thing to note, I have a pending update which is to fix the something which I received at the end of August for the OTA thing and when I put stock recovery back onto the phone to try and do an OTA for that as well, I get the same issue. The only difference is that due to that being the official rom, it also has sound during the bootup but one thing to note (aside from it doing exactly the same and doing a bootloop), the boot animation sound is also delayed by 5 seconds or so, unlike before the update where it plays at the same time as the boot animation.
I am able to successfully restore my TWRP backup of my OS before it attempts something like this and was last working but that's as far as it goes.
I am at a complete loss as I am following any and all tutorials I can find online to the letter and yet I am still having no luck here.
Can anyone assist me on this? It would be much appreciated. Thank you in advance and for reading.

That show your TWRP backup is not stock enough or it is a rooted stock and that is why the OTA failed.
You need a pure non-rooted backup or RUU to successfully update.
What's your device details ?
Run command fastboot getvar all and post here minus the serial & imei no.. maybe someone will be able to point you to right direction.

It's stock firmware that came on the phone, although it is rooted with SuperSU. Whenever I looked online, every forum board said that having a rooted phone wouldn't prevent an OTA, although having a custom recovery would so I would flash the stock recovery back onto the phone and do the update that way which would in turn create this boot loop.
My RUU is/ should be exactly the same as I haven't done anything to change it and also, the updates still come through and are downloaded that way. It also installs (so I think as it goes through the normal process of updating that my phone has always done showing an image of an updating phone with a loading bar at the bottom whilst rebooting a couple of times).
In terms of the details requested, I'm not sure if it will be affected by the rom I just tried installing again for ViperOneM8, but they can be found below:

The version I am on on the stock rom is 4.16.401.10. I'm not sure why that is showing, unless it's because of the ViperoneM8 mod I installed which also features the same patch released by HTC apparently.
Yeah, almost everyone say the same thing and those forum are correct for ROMs prior to lollipop.
On lollipop .. root works differently that is why you can't do update on a rooted lollipop stock ROM.
The only suggestion I have is keep your TWRP backup.
Restore a non-rooted 4.16.401.10 TWRP backup and its stock recovery and do the update. After the update, restore your saved data and re-root or install any ROM that you like.

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:

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
and you are right it is "FASTBOOT USB", not "BOOTLOADER USB" - sorry for the confusion
My phone shows OS-4.30.401.15
I can use a friends Windows laptop and will see if I can give it a try
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
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.

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.
