H3G__001 stock lollipop nandroid

Hi im trying to update to lollipop on my 3 UK branded m8 but im having serious issues upgrading to 4.4.4 eye experience version 3.32.771.3 was wondering if anyone has or could get a nandroid of the stock 4.20.771.2 ROM. I can see an OTA in http://forum.xda-developers.com/showthread.php?t=2701376 but I have no idea how to use those OTA files. Any help would be appreciated.

Post your fastboot getvar all result (minus serial no. & imei no.)
then we know which backup that you really need.
No point to give you 4.20.771.2 backup for now.

cool thanks. I tried your nandroid backup and it starts up fine but I cant connect to my wifi network. It sees the network but it wont connect. It does allow me to connect to another open network I can see but not my own. This happened on one of the stock updates I did too. Any ideas why this might be? or how it might be fixed?

There are two options :
1. Restore 3.32.771.10 backup and its stock recovery image then do OTA to 4.20.771.2
You can have all the needed files here : http://forum.xda-developers.com/showpost.php?p=55322461&postcount=1897
Or
2. Reflashed the untouched 4.20.771.2 firmware that linked here : http://forum.xda-developers.com/showpost.php?p=58781201&postcount=4598
but you need to relock bootloader in order to do that.
a. put your device in bootloader/fastboot mode
b. relock bootloader - fastboot oem lock
c. run these commands
fastboot oem rebootRUU
fastboot flash zip 4.20.771.2_firmware.zip
fastboot flash zip 4.20.771.2_firmware.zip .....( again for the 2nd time)
fastboot reboot
d. check your wifi
For me .. 1st option is a better choice

so I tried option 2 first and that didnt work Then I tried option 1. Flashing 3.32.... worked ok wifi working etc. I then did the OTA that popped up. That flashed and it boots up but system ui force closes and wifi doesnt turn on at all Is there anyway to flash your OTA update specifically and avoid downloading and flashing the one that pops up on screen?

You can't flash OTA manually because your device is S-On.
When you have system ui force close and wifi doesn't turn on at all ... that's a good sign.
What you need to do now is unlock bootloader again with unlock_code.bin that you received from HTC. Then install TWRP 2.8.5.0. Boot to TWRP recovery, select mount - advance - format data - yes
Reboot - check your wifi again - system ui should work and wifi should work too.
Then restore my 4.20.771.2 backup (reason is when re-unlock bootloader and format data .. all data files such as calculator & flashlight & etc are removed)
EDIT : before you do the above, please try boot to recovery where you see the red triangle .. press & hold volume up & press power once.
In stock recovery, select factory reset/wipe data ... reboot

before I saw your message I did a factory rest from stock recovery as you suggested in your edit and system ui force close was fixed and wifi does turn on... but im back to the problem of not being able to connect to my wifi network. I've managed to connect to 2 separate open (public) networks fine but cant connect to mine for some reason. I cant understand why this might be happening.
Thanks for all the help by the way really appreciate it!

That's something I'm not familiar with as I never have that problem before. I read a few thread of this kind of wifi problem .. there are a few suggestions such as reset the router, try change wifi password and a few more like 2.4GHz & 5.0 GHz problem
Maybe someone else more familiar with this kind of problem will step in.

I had a look around and came across this http://www.pcadvisor.co.uk/how-to/g...llipop-solve-wi-fi-problems-on-nexus-devices/ where it suggests changing wifi router channel. I did and it works
Cant thank you enough dude. i've tried to thank all your posts to reflect how many thanks you deserve! At one point when one of the software updates went bad and the screen wouldnt turn on I was told HTC would charge around £200 to fix it! so yeah, thanks

Great :good::good:
Will keep that in mind in case someone else has same problem

Lost RUU backup
Hi I to am trying to revert back to stock on my HTC one M8 (Three UK H3g__00)1 but I have lost my original backups do to an hdd fail the RUU files you posted on here I believe I could have used but the links no longer work
My phone is in a bad way at the moment it is softbricked with the latest version of CWRM on and no OS currently installed, is this why my version main appears blank?
My phone has ended up in this state after trying to install the latest android revolution rom (5.0.1). The rom seemed to install ok booted and setup fine but my Wifi wouldn't turn ON at all. After I rebooted the phone for the first time it got stuck in a boot loop.
I deally would like to get lollipop on the phone and doing some reading I believe with the situation I'm in I have to go back to stock and do the OTA updates to raise my hboot version to 3.18 or above, that way I could install cyanogen 12.1
Apologies for noob question still learning.

Hi ckpv5, thanks I will give this a try now, I did try to flash TWRP 2.8.7.0 recently but when I tried to enter the recovery it just hung and I never figured out why. I will give 2.8.1.0 a go now.
Last night, just to get my phone working I flashed on cm-11-20141112-SNAPSHOT-M12-m8 with open_gapps-arm-4.4-mini-20151203. It all seemed to be working fine and I liked the look and feel of the KitKat cyanogenmod but after I received my first phone call my phone speaker went crazy and gave some nasty distortion out, I rebooted the phone to stop it and now I have the noise on everything if I turn my volume up to mid/high, I'm worried my speakers are damaged. I followed a couple of threads to install the viperapp but with no success, any ideas on this one?
Cheers,

Thanks
CHeers ckpv5 Ifollowed the guide used the files and its all sorted now.
Looks like CM11 has damaged my bottom speaker though i have ordered a replacement.
I do have 1 last question, after all the updating i have now put cm12.1 on and it seems to be running ok however when im booted into the OS my SD card is not being detected. If i drop back into TWRP recovery it does recognise the SD card, any ideas? im searching for a solution now.

I can't comment anything on CM as I never use one .. no experience on CM .. sorry.

[Solved] No OS, No Recovery HELP please HTC One (M8) Unlocked

I have a US HTC One M8 that I bought direct unlocked from htc's site direct in January 2015.
I rooted my device, and was running Paranoid Android 5.1 with TWRP recovery and decided to switch back to stock so I could sell the device.
I downloaded the RUU for my device from htc's site (ruu 6.12.1540.4 for unlocked/developer htc one m8).
I plugged in my device, typed in "fastboot oem lock" until the top of the bootloader said "Software status: modified" and "RELOCKED."
Then I ran the RUU but got Error 155 saying it was the wrong RUU. My device now had a silver HTC logo stuck in the middle. I pressed the power + volume down and got to the bootloader.
But now there is no option for "Recovery" in the bootloader, and the "Reboot" option just takes me straight back to the bootloader.
Here is what it says at the bootloader now:
***Software status: Modified***
*** RELOCKED***
***Security Warning ***
It says OS-4.16.1540.8
In addition, I can't charge without the screen being on. I plug in my phone and it shows the battery icon for a few seconds and then goes back into the booloader with "fastboot ac"
Please help me get my device working & back to stock. Any information or tips will help. I can take photos and provide with any additional information if needed.
Thanks.

Are you S-Off? Is your device Developer Edition?

about error 155, try the following
1. Lock your bootloader through by booting into hboot and then going into fastboot and issuing the command "fasboot oem lock".
2. Once locked, reboot your system.
3. Open RUU and follow onscreen instructions.
Should work. Best of luck

How do I flash a new recovery?
SergioRmz, My device is S-ON, not developer edition, just factory unlocked from htc
Rawfire, I can't flash a RUU. The RUU just gives me an error after a few seconds from starting it - it says try again with a different RUU / wrong RUU (error 155).
Also, could you help me flash a new recovery? Could I flash a new recovery, then flash someone's stock nandroid backup & recovery to get my device to stock? Can I do all of this with a RELOCKED & S-ON device?
I have no idea how to flash a new recovery so instructions would be very very helpful
One final question - Can you tell me the best way in my current sitatution to get my device to stock without S-OFF? I'm willing to try anything (except S-off) to get my device to stock so I can sell it / trade it in.

I can suggest couple of things, unlock the bootloader to install custom recovery and then you can flash any compatible rom,
Or to suggest some exact RUU, what's your device's exact model?

Just tried this, said "Device was already locked!"
Then tried RUU again, still said Error 155 "please get the correct RUU and try again"
When I unplug the phone it says error zip file with RUU written under it, and I had to press power + volume down to get it to the bootloader again.
Thanks for your continued help rawfire.

Is that os-4.16.1540.8 written on the bootloader ? If yes, you have a Dev Ed device, the other RUU meant for EU won't work for you.
Post fastboot getvar all (without serial & imei no.) then we know the actual device version
If it is indeed a Dev Ed device, what you need to do :
1. flash the 6.12.1540.4 firmware
See this : http://forum.xda-developers.com/showpost.php?p=64407841&postcount=2862
How-to, see this : http://forum.xda-developers.com/showpost.php?p=64416322&postcount=2864
2. Run RUU 6.12.1540.4 after the firmware is installed
Or the easy way is :
find 4.16.1540.8 RUU and install this then after, do OTA to 4.17.1540.9 then 6.12.1540.4
Edit : here is the direct HTC link for 4.16.1540.8 RUU - http://dl3.htc.com/application/RUU_...G_20.68.4196.01_F_release_411207_signed_2.exe

Then it is confirmed that you have a Dev Ed device.
Go with the easy way that I posted above. Install RUU 4.16.1540.8 then do OTA to the latest, done.
Additional - as you mentioned you're going to sell this device, I suggest after the last OTA 6.12.1540.4 is done, run RUU 6.12.1540.4 to remove all the OTA leftovers in device. You'll have a clean device after the last RUU.

4.16.1540.8 RUU has been stuck at "Updating.. (0/7) Sending....." for 20+ minutes now. Phone is showing just the silver htc logo, no progress bar or anything else.
Should I try flashing the 6.12.1540.4 firmware now? Thanks for the help so far ckpv5
Also, is the phone charging while connected to the computer & updating? Just asking since I can't see the battery percent (no OS) and don't want the phone to die while flashing.

This show you have USB/PC connection problem. To run RUU you need Windows PC with USB2.0 and the latest HTC USB drivers installed.
See the How-To linked above for the HTC Sync Manager download page, install it as it will install the USB Driver, then uninstall the Sync Manager but leave the driver
While flashing .. charging is minimal, won''t be enough if you don't have at least 70% battery

Thanks for the info, going to reinstall HTC Sync Manager and try again. Does it need to be USB 2.0, or can it be USB 3.0?
Also, how long can I charge without having the screen burn because when I plug in the phone to the wall or the the computer, it shows the bootloader screen. It stays in that screen while charging so I don't want to charge for extended periods otherwise screen will burn. Can you tell me if I am right on this?

You must use USB2.0
When in bootloader, choose power down then charge it, you'll see the progress and there will be no screen burn.
If you don't have a USB2.0 - other options :
Option 1:
Clean your PC temp folder - just select "run" then type %temp% and clear all that your can.
Run the RUU again (not necessary to connect to phone), when the RUU dialog open, check in %temp% you should see two new folders are created. Find ROM.zip in one of the folder, copy out the ROM.zip to your desktop. You can close the RUU dialog box.
Rename the RUU.zip to 0P6BIMG.zip (that's a zero not "O") then put it on your microSD.
boot to bootloader then select hboot or boot to hboot - it's your choice
hboot will scan the file and ask to volume up to update
volume up
finish, press power to reboot and do all the setup stuff
remove 0P6BIMG.zip from your microSD
now you have ROM installed then can proceed with OTA and the rest.
Option 2:
Re unlock your bootloader again with your unlock_code.bin that you got from HTC.
Install TWRP 2.8.7.0
Restore a clean non-rooted 4.16.1540.8 nandroid backup and its stock recovery
Reboot.. setup.. OTA..OTA.. done.
You can get all the needed files in the link shown in my signature
So now .. you have 3 options to choose.
1. RUU method
2. 0P6BIMG.zip method
3. Nandroid method
I got to go now ... good luck

Thanks a TON ckpv5. I followed your instructions & reinstalled HTC Sync Manager, then connected the cable to a USB 2.0 port instead of 3.0. The RUU method you originally suggested worked like a charm. I now have stock HTC software, stock recovery just like I wanted. I then did an OTA to the latest software. When I sell my device in a few days, I'll be sure to follow your tip and run the latest 6.12.1540.4 RUU to clear off all the old OTA files.
Many thanks again for your help - hopefully others will see the 3 solutions you posted.

Marshmallow OTA failed

Hi All,
I'd like a bit of advice/help.
I went to update my phone to Marshmallow OTA and it did it's thing. I left the phone for hours and it appeared to be stuck on android is starting. I restarted the phone and it's now stuck on the HTC splash screen. Recovery options don't work etc.
I've searched around and there are loads of guides but these tend to lean towards rooting. I'm not looking to root but instead looking to get the phone back to factory software that it was originally on.
It's a UK model locked to the 3 network. See below for info taken from the phone.
Thanks in advance.

Can anyone assist? I'm desperate here. I've not had a working phone for days here. The guides I've seen appear to apply to either previously rooted phones or suggest I get the file from the HTC us site but my software versions is newer than those listed.
I have HTC tool kit installed and android studio so any tips would be greatly appreciated.
Thanks.

Is the bootloader UNLOCKED ? or LOCKED or RELOCKED ?
If it is UNLOCKED, I can suggest to restore a non-rooted stock backup.
If it is LOCKED, you can try going to recovery and do data wipe from there (provided that is stock recovery)
and don't use Toolkit .. it brings more harm for less experience user

I've managed to unlock the boot loader. How do restore using a non rooted standard backup? Thanks for replying.

1. You need these files adb/fastboot and HTC USB drivers installed
Read this for the files : http://forum.xda-developers.com/showpost.php?p=64926362&postcount=4
2. Read this thread post #1 on How-To restore a backup and install stock recovery
http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
3. Install TWRP 3.0.0.1 - https://dl.twrp.me/m8/
4. Download and restore 6.13.771.4 backup (from post #3 from link on no.2)
5. Download and install 6.13.771.4 stock recovery (from post #4 link on no.2)
6. Reboot and see whether it works or not

Thanks for that.
It's now at the stage where the apps have been optimized and it's now just hanging at the "Android is starting..." "Starting Apps...".
This was my original issue I had when the software was updated first time round.
Any clues on how to get past that?
Thanks

No clues ... hopefully it's not hardware problem.
What you can try .. restore one version lower, then do OTA becuase OTA will reinstall the firmware.
Restore 4.25.771.6 backup & its recovery.img then check for OTA, download and install.

The downgrade worked and I updated to Marshmallow but for some reason, the phone still hangs on Android is upgrading and starting apps. I'm at a loss as to what to do next. I don't want to use a phone on an old version of software and never upgrade.

So you can boot the lollipop but not Marshmallow ?
I don't know whether you can find htc signed 6.13.771.4 firmware.zip .. this is the only thing I have in mind. Maybe manually flashing the firmware.zip will fix your problem.
I'm already in bed as I will be outstation in the morning. If you can wait, just run the lollipop for the time being. I will give you the firmware.zip on Sunday night (GMT +8) to try to fix it.
Hopefully someone else will be able to help you while I'm not around.

Would changing the CID and MID and selecting a different software package work perhaps?

You only can change CID & MID on a S-Off device.
To S-Off your device you need to pay usd25 for the Sunshine app.
Why don't you try a Marsmallow custom ROM to see whether you can boot it.
If you can at least you can run a Marshmallow ROM until you fix your problem.
I'm signing off now .. goodnight & good luck

Thanks, if anyone else could assist that would be appreciated. I've installed a custom marshmallow rom and all went well but it still suffers with the same fault. It hangs on starting apps. No matter what I do this phone doesn't like Marshmallow!

Hi, I'll wait for your offer of the firmware zip and try that. For some reason this phone doesn't like anything to do with marshmallow.

Sure can .. I get back to you once I'm back from outstation tomorrow evening.
1. Restore the Marshmallow 6.13.771.4 backup if you're on different ROM
2. Download firmware.zip
3. Put your device on bootloader/fastboot mode and put the firmware.zip in your fastboot/adb folder and open a command prompt from this folder
4. Run below commands
fastboot oem lock - to relock your bootloader because your device is S-On
fastboot reboot-bootloader
fastboot oem rebootRUU
fastboot flash zip firmware.zip
You'll see -
if failed : FAILED (remote: 90 hboot pre-update! please flush image again immediately)
repeat fastboot flash zip firmware.zip
fastboot reboot
check whether your wifi is working now ..

Thanks for that, what I did in the mean time was use the sunshine app to S-Off and change my CID and MID to a deveolper phone. All was fine until the phone upgraded to marshmallow. It still hangs on the Android is upgrading starting apps. It seems no matter what I do this phone will not accept marshmallow.
Any other ideas as to why? So odd why marshmallow doesnt boot past this screen.

Since now your device is S-Off .. instead of updating it to Marshmallow, have you tried running a Marshmallow RUU on it ?
(Assuming your current firmware installed is 6.12.1540.4)
Here is the RUU : http://www.htc.com/us/support/htc-one-m8/news/
If after running the RUU and still the same problem .. I have to say that I'm out of idea.

I'm downloading one now. I'll update you with the outcome. I'm at a loss as to why this is happening. What does the RRU contain?

It has every images that a device need. Means it removes everything on your device and replace them with new images that come from the RUU.
One thing to note, other that those drivers and HTC USB Drivers that you need (in my previous post), you need a PC with USB2.0

It's currently optimizing apps so we'll see if it boots up. Is there much difference between doing an OTA through all the various updates and going straight via an RRU?

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.

"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.
I tried to change CID and s-off but it's not working.

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.

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.

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-baseband: 1.24.21331147A1.09G

(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

update: Well, a partial success
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
Alan

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
