How can i get my HTC M8 EUROPE model to completely STOCK - One (M8) Q&A, Help & Troubleshooting

I have a htc M8 UL
Radio_1.29.214500021.12
OP6B10000
S OFF
Unlocked bootloader
Ive tried relocking the bootloader and using htc RUU exe but it didnt work
ive tried the hboot with the ( maybe ) PROPER ruu zip ( 0P6BIMG_M8_UL_M60_SENSE70_MR_HTC_Europe_6.12.401.4_Radio_1.29.214500021.12G_20.72.4196t.01_release_464360_signed.zip)
BUT it said ' error saying device halted due to large image update fail!
press power to reboot.
Do i really need to turn s off and rewrite the cid and mid or there is another way ??
Please help ( my first thread)

The problem is
To get the stock ruu flashed i need to modify the cid and mid
to modify them i need to turn s on to s off
to do that i need sunshine witch it says " there is a problem with your rom"
im stuck i guess

Try this method. I just reverted back to stock tonight and I'm now completing my OTAs. Seems to be working just fine for now. Make sure you follow each and every steps. Make sure you choose the version with good CID and MID.

Based on what you posted, the phone is already s-off.
However, the "large image" error is NOT a result of wrong MID/CID. It means something else is wrong. Are you using the SD card method to flash the RUU, or fastboot? If fastboot, what are the exact commands you are using?
Also, you do not need to change CID/MID if you are running the signed RUU intended for your specific model. There are many "Euro" versions of the M8. And not all of them will work with that particular RUU. In order to verify whether the RUU is correct or not, we need more info. Do fastboot getvar all, and post the results (delete IMEI and serial number before posting).

This method is certainly valid. Although requires more steps than running RUU. If in fact, the OP has the correct RUU for his version.

[Q] How do I change my CID (and get EU RUU)

I have gotten myself a s-offed HTC One X from a local carrier with their firmware on it so I have no real hope of fast updates...
CIDgetter says in the top left I have CID of 11111111, yet going down to ro.aa.maincid says TELENZ001 - the carrier
Obviously I am s-offed and can get into the bootloader, how do I go about changing my CID and flashing a European RUU?
Have you tried just plugging in when in fastboot and running the RUU? If you really do have Super CID it'll just work
Sorry to ask this but have you contacted the guys in the s-off thread? They may be interested in hearing from you.

Can you make a picture of the bootloader. To see what version HBOOT and radio you have. Maybe this is causing the issue.

Boot phone into fastboot, connect to PC, run RUU - not a lot else to do!
It'll either work or give you an error and reboot, with no changes made
Cid-11111111

I realise that ofcourse, its the maincid I want changing. I assume flashing the EU RUU will change that maincid?
On that note can anyone link me to the RUU I would want?

If you have superCID then choose whatever RUU you want from HERE. It will not change your CID if you flash a particular RUU.
May I hook on to this.
My CID is O2__001. So I want to change it into 111111.
When I boot into fastboot and give 'fastboot oem writecid 11111111' it says:
FAILED (status read failed (Too many links).
I've tried different usb-ports, different usb-cables
Or is there another way to change the CID?
Bootloader is unlocked (HTCDev)
HBoot: 0.43.0000
Softwareversion is still 1.26.206.2, no updates available
Someone can help me?
Thanks in advance

If you have S-OFF you don't have any need for HTCdev. Being superCID your phone can get OTA updates as long as you have stock recovery.

Thought that might be the case, as for flashing the RUU, is it the standard CWM way or with the fastboot files you mentioned in the video in your sig? Do the same instructions apply from it for me?

[SOLVED] T-Mobile M8 Stuck In Recovery With ReLocked Bootloader and No ROM!

The title basically says it all but I'll describe what I did so hopefully you guys can help.
Today I got tired of the ROM I was running and I figured I'd update my firmware before I flashed a new one just cause I hadn't done it in months. So I went and followed this guide: http://forum.xda-developers.com/showthread.php?t=2696282
I used this firmware: https://www.androidfilehost.com/?w=files&flid=32788
My CID is T-MOB010 just like the firmware's and I thought it would be a pretty simple thing, so I got to work.
First I rebooted to fastboot USB and did fastboot getvar all to make sure everything lined up, then I relocked the bootloader and did fastboot oem rebootRUU, all successfully.
Then I flashed the firmware and it all went great but I forgot to flash it a second time. I'm not sure if it's required, but anyway...
After it flashed successfully I did a fastboot reboot and my phone tried to reboot but it stalled on the white HTC splash screen, then went black, then the splash screen returned, then black, then it went into the stock recovery.
The stock recovery functions just fine and I attempted to just clear the cache and reboot but it did the exact same thing.
I don't currently have a stock Nandroid or RUU on my phone and I'm not even sure I have a way to get one on there besides using someone else's phone to put one on my SD.
Can anyone help me out? Is it even possible to get out of this? My bootloader is relocked and my phone can't get S-OFF (tried awhile ago multiple times). As of now I am all out of ideas/experience so I'm hoping you guys can help me. Thank you!!
UPDATE: I got myself into the HBOOT so I think I should be good now but I'll keep this around just in case.
Update: Once I got into hboot all was well, I just flashed TWRP again and got it going. Thanks everyone for the help!
Did you get it going again?

Just use the official RUU.exe which runs from a PC (with phone connected), not from the phone.
http://www.htc.com/us/support/htc-one-m8-t-mobile/news/
RUU will also update your firmware.
Also, the firmware you linked is not the latest. Its the Android 4.4.4 firmware. The 5.0 (Lollipop) firmware would be 4.20.531.4

Its not what your top post says, so its not clear whether you were trying to put the RUU.exe on the phone (which is incorrect), unsuccessful in putting on the phone or running an RUU.zip, or did the latter in addition to trying to run the RUU.exe from the PC (which was not originally mentioned). If the last one didn't work, it would help to have more details on failure mode, error messages, etc.

Same kinda problem.
I'm stuck in bootloader.
Any key I just brings me back to this again.
Even in HBOOT selecting Recovery or Factory reset does nothing other than bring up this screen.
Powering down and then on again has the same result.
I was trying to get back to stock. Typed in fastboot oem lock and after that... the problem started!!
Any ideas??

This is intentional. When you relock the bootloader, it renders the phone unbootable and expects the RUU to be run.

You shouldn't be assuming what RUU to run. What is your CID and hboot number? What RUU did you try to run?
HBOOT is 3.19.0.0000 CID, can't find.
RUU is M8_4.16.401.10_Europe.exe

The OS number (3.32.206.9) shown on your hboot screen (pic in your top post) indicates that is not the right RUU. The number in the x.xx.206.x is carrier specific,and seems to indicate that your phone is the O2 UK version. Running an RUU with version x.xx.401.x won't work. The number in the "401" spot would need to "206" for it to be the right RUU.
Not sure, but I don't think your CID has RUUs. If that is the case, your best bet it to unlock the bootloader again, flash TWRP back to the phone, and restore a nandroid with your software number (3.32.206.9) if you can find it. Then flash stock recovery back to the phone. That is as close to "stock" as you will get, if there is no RUU for your CID version.

Thanks redpoint73. Looks like that's the only way to go!!
By looking at the radio, you need the Euro Version RUU. Looks like we gotta be detectives sometimes, lol.
Ok, I've unlocked the bootloader and am back to where it was.
It's running 5.0.1, Sense 6.0 and Android Revolution HD 34.6 by mike1986
I would like to clear that off and get back to stock with OTT updates.
Revolution HD 34.6 seems to use an awful lot of data. My other M8 has stock on-board, has identical apps etc and doesn't use nearly as much data as this one!!
Any further ideas??

I'm downloading that now. BUT...........
Because of all my faffing on!! there's NO OS on the phone.
I'm really struggling now:crying:
This is my position now. Totally unusable phone!!
I would appreciate ANY help on getting back to as near as normal as possible.
Thank you.
I should add, the RUU messages are from trying post #16.
And the saga continues!
I found a nandroid backup with the same s/w number as mine, downloaded it from MEGA (it seemed to d/l ok).
When I ran it through TWRP I got signature verification failed.
This phone could end up in the depths of the river Tyne

What hack14u neglected to mention, is that to run another version's RUU, you need s-off ($25 by sunshine), and then you need to change your MID and CID.
Relocking the bootloader (to run RUU) renders the phone with no OS, this is by design.

Hang in there, modding phones can often be an exercise in frustration. But the phone is quite recoverable, as long as you perform the correct steps.
A nandroid is not a flashable zip (such as a ROM). It needs to be restored in a very different way, its described in Post 3 of the stock nandroid thread (assuming that is where you go it from) under Question & Answers.
To summarize, you need to:
1) Unpack the zipk, which is a number of folders
2) Move the folders to the proper location on the phone's internal storage (removable SD is also possible, if you setup TWRP to back and restore to that location)
The exact location if very important (its described in Post 3 of the stock nandroid thread), since when restoring a nandroid, TWRP will not see the file to restore if you have it wrong. This is in direct contrast to installing a ROM zip, in which TWRP allows you to browse anywhere on the storage to find the file to flash.
3) Choose the menu option to RESTORE, not INSTALL

Can you downgrade an update?

I have an s off unlocked phone. Any of you know if its possible to downgrade to an older update? The new us update is affecting my calls and signal so i need to go back.
Just run the old RUU exe and you'll be set.

Depends. If his handset is s-on he can't "just" run the old ruu. With s-on you can't downgrade the bootloader to a lower version.
So it's either doable with s-off or look for the OS via a backup and try to restore that and run it on the new firmware.

So in the meantime i reflashed twrp and recovery and restored a backup.
But in the conclusion all i want now is to revert to full stock (i have no backup of that). Can i do that with s-off and bootloader re-locked? the reason that i want to do that is to recieve further updates ota. The reason i did all this to my phone was because the 4g was working when it wanted (not only 4g but mobile data in general). Now i'm thinking of reversing to stock, maybe future updates will solve this or to send the phone back for waranty.
So i need to flash stock, can you guide me from this point to achieve that?
My current software is 1.95.401.3, the phone was unlocked but not developer edition.Cid is HTC__34.
Help me what to do next and i will do one by one until i succeed (sry for my bad english)
@pocutzz you need SuperCID. In download mode, connect phone to pc and open a command window on your computer, type out "fastboot oem writecid 11111111" (I advice you copy and paste this but without the quotation marks), and then you will gain SuperCID. With this, you will be able to install any firmware/RUU regardless of CID.
@ OP, if you want to downgrade, since you are S-OFF there is no need to relock bootloader. As long as your have SuperCID you can downgrade to any firmware just like that. Download RUU and run it.

if you RUU you should still be able to receive OTA afterwards but don't count on me for that one as I've never restored back to stock before. You can search for previous HTC 10 RUUs on google, I recommend not going too far back and just going on the update before the 1.95 one (1.90 I think). Not every version has an RUU so if you can't find an RUU you want, try and find an older version.

It should be fine, yes. Make sure you have SuperCID and remember that you do not have to relock your bootloader when running the RUU as you are already S-OFF

i re-locked before i run sunshine for s-off. i will try to do that in a few minutes
i have done superCID, but before i try to flas the ruu, wanted to ask you, after that what remains? like s-off,root,twrp,custom recovery?
Okey so i did the superCID, in download mode it shows me the 1111111 but on the phone when i run CID Getter still says HTC__034 (that is how it suppose to show?), i copied from here like you said.Downloaded the ruu.exe from htc website,and when it runs it resets my phone to download mode,the bar goes instantly to 100% and the ruu installer says the 155 error,incorect version i think.
What do i do next?
Maybe MID problem?i've read something about it for HTC M8 i have mid 2PS620000. Maybe the ruu.exe on htc website is for US and i need EU?
Later edit: So i put the global variant with .401. in the sd card and it started to flash, i will se what is what...

S-OFF will never be wiped, if you have relocked then it will remain relocked state. Everything else is wiped and restored to stock including recovery, system, data, Internal Storage MIGHT BE WIPED I am not so sure.
if it shows SuperCID in download mode it should be fine. All you needed to do to get it was to execute that command line I posted before.

if it shows SuperCID in download mode it should be fine. All you needed to do to get it was to execute that command line I posted before.

thank You for the info.i just flashed from sd card the 401 version, an got the updates,think everything is okey,i will write again after all is good. Ty very much
about 3 friends of mine have bricked htc 10 when trying to downgrade the firmware (Sprint, KKDI and unlocked variant all s-off) I want to ask if I can use the image to sdcard method to unbrick ???

boot loader . .

How do I unlock the boot loader when there is no oem setting to allow unlocking the boot loader in developer options? I have the token the phone is running marshmallow. It is S off and has CID 11111111. One thing can I flash TWRP to my phone without messing with the boot loader. If so then I can just use TWRP to flash the model ID and EU RRU thanks in advance. Just read I cannot flash TWRP without unlocking the boot loader.

I'm not sure what your exact situation is but i don't think OEM unlocking through Settings is an option. Have you tried this ... See link below

Yes my comment is vague, I want to unlock my boot loader but cannot. All settings on the M8 are set such as USB debugging and I have the unlocking code from HTC. When I proceed to unlock the phone and choose option to unlock the phone, phone reboots but the boot loader is still locked. On the HTC web site it states with Marshmallow this can happen and you must go to developers options and highlight OEM option to unlock the boot loader but the option is not there and I'm stuck. Thank you for your reply
Did you try fastboot oem unlock? If it's soff and supercid, should be all that is needed

Far as I know, this will not work.
May need to use the following method (if unlock token doesn't work) and root is also required:

It is correct, you cannot flash TWRP with a locked bootloader (needs to be unlocked) by definition.
But you also don't flash an RUU in TWRP. You also may not need to change the MID, depending on what version you have.
Please do fastboot getvar all, and post the results (delete IMEI and serial number before posting). Need to verify some details before supplying advice, which may be harmful to your device.

Your model ID (MID) is for AT&T and Developer's Edition.
You may or may not need to change the MID, in order to run the Euro RUU. Sometimes (often) having SuperCID (11111111) will bypass the MID check for RUUs. So I would suggest running the RUU, and see if it gives you model ID error, or if it just work (before messing with the MID, if you don't have to).

Actually this whole thing started when I installed the developer RUU on the phone. After this I noticed when I launched the camera a message came that the lens is blocked. I think it's a RUU issue. You see the RUU I had before which was Kit Kat camera worked but many other issues. The marshmallow RUU was downloaded from a member of this forum forget his name

Unlikely an issue with the RUU itself. I was on the Dev Edition RUU for a while (as have many others), and the camera worked fine. But it's not a bad idea to try the Euro RUU, and see if that helps.

Wow, that is remarkably vague. The file doesn't have a version number, or name? Not providing any useful info, forces us to guess. Lucky for you, I have a pretty good guess.
Try the following Euro RUU, and instructions:
https://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
Alternately, if you have an SD card, rename the RUU zip to 0P6BIMG.zip put the file on the SD card, insert in phone, and reboot to bootloader, and it should install automatically.
Let us know if it installs, or if you get error messages (and what the error messages are, specifically).

Recovery doesn't matter for RUU install, it will be overwritten by stock recovery regardless of what is presently there.
Model ID is what I mentioned before. The RUU may or may not work with your MID. If it fails with model ID error, we know we need to change the MID. If it works, then it works.

AT&T has nothing to do with it, it's not what "oem blocked" means. This is probably pilot error. Do you have root, since it's required to change the MID?
And you are not following my advice why, because of some assumed or imagined fear that isn't based on any fact? Flashing the RUU with the wrong MID is not going to harm the device. The worst that will happen is an error message (wrong model) and the RUU will not install. The phone remains exactly as it was before you tried the RUU. And meaning you have to change the MID to run the RUU.
Best case, the RUU works, and you no longer have to mess with changing the MID.

oem unlocking being "missing" is not the problem. It wasn't on most OS builds for the M8, and was only added later. In fact, I'm not sure it was ever present on this device (or maybe just some versions). If it's not there, you don't need to enable it. Unlocking the bootloader should work normally.
So clearly, something is wrong, if you are doing the bootloader unlock, and it doesn't work. Let's try to run the RUU, and go from there.

Guys please get me a RUU for HTC_J15 arabic.

i have an S-on , bootloader unlocked device.
its showing 3.16.401.2 .

EDIT, NOT SURE IF THIS WORKS WITH S-ON. YOU WILL HAVE TO DO SOME DIGGING. I HAVEN'T BEEN S-ON IN PROB 7 YEARS, SO I FORGET. YOU WILL NEED TO DO YOUR OWN SEARCHING TO MAKE SURE THESE DIRECTIONS WORK. THEY ARE FINE FOR S-OFF, AND MAYBE S-ON. 4a, SD-Card METHOD, SHOULD BE FINE TO TEST. IT IS THE SAFEST METHOD AS IS.
1) Download the RUU:
https://androidfilehost.com/?fid=673956719939830809
2) Download this htc_fastboot.exe
https://androidfilehost.com/?fid=95897840722646249
3) Put RUU and htc_fastboot.exe in the same folder with your adb files in it. If you don't have them, I have kindly uploaded the files for you... All you need to do is extract it.. Right click, Extract to htc_Fastboot10/
4) Instructions to flash the RUU:
Code:
adb reboot bootloader
htc_fastboot oem rebootRUU
htc_fastboot flash zip 2PS6IMG_PERFUME_UHL_O80_SENSE90GP_MR_HTC_Europe_3.16.401.2_R4_release_519849.zip
htc_fastboot reboot
4a) Instructions to flash the RUU - SD-Card Method:
Code:
rename
2PS6IMG_PERFUME_UHL_O80_SENSE90GP_MR_HTC_Europe_3.16.401.2_R4_release_519849.zip
to
2PS6IMG.zip
Place onto root on phone SD-Card
Reboot to download mode
Press VolUp to confirm and proceed with the flash, or press VolDown to cancel
It should stop at "end UI updating. Press Power to continue" - the phone will now shut off. To turn it back on, press and briefly hold power again.

This is the exact thing,
Unlocked bootloader throught HTC dev. installed TWRP. Downloaded Leedroid files and i saved them in sd card. And went to TWRP and wiped . then i flashed . went through the customization options which leedroid gives, i chose a kernal too in the option. and flashed.
Flashing finished.
I rebooted the phone. A leedroid logo came up . it stayed their for like 10 - 15 mins. i switched it off by pressing the power button more than 10-15 seconds i guess. Then i went to recovery and restored the backup. and i was on a black screen. I tried to Flash a RUU but it was failed(i guess the CID no. was not right) . Then i wiped again and restored again. I thought my phone was dead . i was trying to remove the sim card from my phone and put it in an old lenovo. By mistakely i removed the SD card and error came while restoring. i simply pressed reboot and my phone was somehow turned on. It was factory default. But my sim card is not working.
Between, i am having a doubt. The RUU is only based on the CID number ? the number in download mode (...401.2) has anything to do with it ?
Are you on Oreo Firmware? As i know there are no RUU for oreo firmware, so you must to downgrade. On S-ON, you can't just flash RUU if you want to downgrade. Follow step from this thread https://forum.xda-developers.com/htc-10/how-to/how-to-rollback-oreo-to-marshmallow-s-t3787101/page2 (see post #15). I just downgrade from oreo to nougat using this guide.

No, you shouldn't
So you are pulling SD cards and or sim cards out of the devixe while it's booting/flashing.....for god sake man. Thats stupid.
A RUU is made for many cids, actually the 3.16.401 RUU is for every device that has that number is the Download mode. So if your phone has that the RUU is correct. When the download mode says 2.41.401 then you need that RUU which is also available here at xda. There is no other. And flash leedroid again and wait longer. Have patience.
Or flash the RUU, rename the zip and put it on the sdcard, boot to download mode and let it flash.

No it's kinda disturbing that you are going from left to right as you also said you successfully downgraded your device to nougat so why do you need the RUU ? If you successfully downgraded to nougat you can also update officially again to oreo so that would disable the need of the RUU. You are giving the idea that you need the 3.16.401 RUU but you don't even need that one.
The only thing you are doing in this thread is repeating people's answers and confusing the original poster.
To the original poster of this thread :
Download the 3.16.401 RUU i linked, use the SD card method and follow that. It will flash the device back to stock. If that doesn't work you are doing something wrong.
