It says you are S-ON, though further down security is off and you have SuperCID. You can flash any firmware package you like now. Do you know your original CID number or what stock RUU you need? You can also go here and take a Nandroid to get back to stock and then OTA to Marshmallow.

now a lot of rom says i need marshmallow base to flash that rom.now my quest is do i need to flash a marshmallow ruu to flash other mm custom roms?

and if i need to flash the ruu,do i need to change cid to the firmware cid or get s on?or can i just flash the ruu through fastboot with supercid and s-off?

and will ruu change my cid number or change my phone s off to s on?
[One (M8) Q&A, Help & Troubleshooting] Einwod:
Your firmware suggests AT&T, your MID is T-Mobile. Someone has already played about with the internals of your device. Do you know what the original CID/MID combination was before? You are S-OFF and should stay that way as it gives you complete control over the device. Running an RUU will not make it go back to S-ON, only you can do that with commands. The RUU, if you find the right one, will return you to a stock condition with stock recovery allowing you to obtain OTA updates. Your firmware is currently a Lollipop version, so you do really need to update. There are threads here where you can change the MID number to other variants, though you need to be very careful as you could possibly end up with an expensive paper weight. Have a look at this thread for changing MID. BE CAREFUL and follow instructions to the letter. Look at this page for RUU download for the US versions. Read everything carefully and you cannot go wrong.

[One (M8) Q&A, Help & Troubleshooting] xunholyx:
You can only downgrade firmware if you are S-Off. But since it's important to you, you can go here to gain S-Off (it costs $25), then flash/run an older RUU.
[One (M8) Q&A, Help & Troubleshooting] Fifa91:
I don't give 25$ for that i want do it for free i don't believe why HTC make that so much complicate i did not know that the stock rom file it can be flashed in custom recovery but this is too much for me then S-off then unlock bootloader why is so complicated i'm pissed off IR blaster is not working on 6.0 android when i call friend over a viber instead of turning ear speaker it turns upper main speaker like a tablet and its very poor battery life i'm realy sad, dissapointed and angry on HTC company i lost 2 days in searching of that how to downgrade my phone and still nothing i'm losing my precious time and nervs what i can to say. :(
[One (M8) Q&A, Help & Troubleshooting] xunholyx:
You can't flash firmware in recovery. And gaining S-Off also unlocks the bootloader. It's far from complicated.

And you don't have to flash a custom recovery. If you want to downgrade, you do need S-Off though.

Also, it isn't just HTC. Almost any model of phone won't let you downgrade from complete stock.
[One (M8) Q&A, Help & Troubleshooting] Fifa91:
Let's be honest its not like other phone its far diferent like other phones take SAMSUNG,SONY and some premium chinese (like a ONE PLUS ONE, MEIZU, XIAOMI) in example. Sony & samsung is very easy to modify and in few clicks you back phone to stock in the really short time so that's the reason i am not big fan of HTC sorry for strong langauge or insulting HTC company.

Hi, I have my HTC M8 on android 5.0.1 - build 4.16.401.13. I did root it but I can't update to Android 6.0 6.12.401.4 as I get status 7 error. What's the easiest way of updating to the newer version? It's not my main phone so I can backup apps with titanium and restore once updated.

Would I need to restore to stock unrooted 5.0.1 - build 4.16.401.13 and then OTA to 6.0 and then reroot? That seems easiest.

[One (M8) Q&A, Help & Troubleshooting] redpoint73:
You can't downgrade the OS on any stock Android device (you have to do some degree of modding, whether it be root, unlock the bootloader, etc.), from any manufacturer. This isn't anything HTC specific.

---------- Post added at 11:03 AM ---------- Previous post was at 10:42 AM ----------

Your other option (which is free) would be to unlock the bootloader via HTCDev.com, flash TWRP custom recovery, than install a stock Lollipop TWRP backup.

But you can't downgrade by RUU unless you have s-off, as xunholyx mentioned.

Once you start talking about downgrading, you are talking about a modification (mod) that isn't manufacturer sanctioned/recommended. So you can't blame HTC for making things "difficult", as you are doing something they don't intend for you to do.

And once you go down the road of modding the phone, that requires a significant amount of research and learning; which is expected on anyone that wants to mod their phone. My advice would be to stop complaining, and treat it as a valuable learning experience that will benefit you in the future.

HTC One M8 - Decrypt Storage "Bug"

I have googled and searched here.. seems to be a 'known' issue on certain devices? (Although I was never clear as to how/why this happens?)

Anyways..

I have an HTC One M8, my wife has an HTC One M7. and my son also has an M8..

My son brought me his phone the other morning and showed me the screen/message it was displaying when he turned it on. (The dreaded Decrypt Storage screen)

The phone is 'bone stock'..

never been rooted, never had any bootloaders added...no recovery anything.

when I booted the phone up holding vol down & power button..

I'm brought to the screen with the phones details..

It displays:

Software Status: Official

** LOCKED **

etc..etc..

along with some other stuff.. (I can post if relevant) ....

Is there an actual way to fix this?

All attempts at recovery and factory reset have failed... (cant mount /data..etc)

Obviously, the first choice would be to retain any data/apps..etc.. but if it can be done.. (so be it)..

I have read things, like TWRP, sideloads..etc.. but really, they are just words to me at this point. Without directions/steps on how to execute these tasks.. (they dont do me any good unfortunately)

I have read installing 'TWRP' and booting to recovery form that will help 'fix' things, leaving the data in tact?

How do I install 'TWRP' on an HTC One M8 phone? And is this the recommended approach?

I have seen things like the HTC Tool mentioned.. something call RUU?...

But cant put all these 'comments' (without context) into a 'plan' that I can actually execute.

Do I put some file(s) on the SD card and load/boot from there?

I dont think the ADB was ever turned on in the phone itself? (does it matter?).. as I said.. this is a new/stock, (1+ year old phone)...

AT&T are just trying to get me to buy a new phone.. (spit!)

Can anyone offer up some help/directions/steps to get this phone working again?

Thanks!

[One (M8) Q&A, Help & Troubleshooting] Einwod:
If you wish to return to stock, you can find the RUU here. It will wipe everything off the device. So backup what you want to keep, photos etc.

[MENTION=3741261]Einwod[/MENTION]

How do I 'back things up' if I cant even access any part of the phone?

This will be like the phone was just purchased?

Do I need to contact AT&T again to 'activate' the phone or anything afterwards?

Do you recommend this vs trying to install 'TWRP'? (whatever that is.. and however that is done)??

thanks
[One (M8) Q&A, Help & Troubleshooting] Einwod:
OK, you got me on that one. You would need TWRP to get pics etc off the phone, but then again, you can boot into a custom recovery without actually flashing it. The command is: fastboot boot recovery (name-of-recovery).img You would then be able to get things off. When you run the RUU it will be as the device came out of the box, yes. I have no idea about "activation", but if you need to, then just call them.

TWRP is a custom recovery which allows you to flash custom ROMs and other additions to your device. You would need to unlock the bootloader through HTCDev.com before flashing the recovery. There are lots of help threads here on XDA that will guide you through the process if you choose to go that direction.
[One (M8) Q&A, Help & Troubleshooting] xl97:
hmm.. well I dont think things are working well :(

I downloaded/installed:

HTC Sync Manager

RUU.exe file

I ran RUU.. followed directions..

clicked the 'next button' when told to..

watched the screen messages.. and the screen on phone where green progress bar was 'moving' .. in the end it finished.. progress bar was full, but had 1 exclamation point after progress bar.

I closed Syn Manager and tried RUU again.. this time its sorta 'hung' at 28% (Updating System)... I hope it 'takes' this time around..

---------- Post added at 04:53 PM ---------- Previous post was at 04:40 PM ----------

RUU failed (again)

ERROR [152]: IMAGE UPDATE ERROR

"The ROM update ultilty cannot update your Android phone."

"Please get the correct ROM Update Utility and try again."

(what a joke)

So if this was supposed to be 'the' fix (but wiping all data).. it still doesnt work.

ROM downloaded form the linked page:

RUU_M8_UL_L50_SENSE60_ATT_MR_Cingular_US_4.28.502.2_Radio_4.0.U605611@50319A_40.45.C33065.00_F_release_446225_signed_2.exe

Says same version as what is on the phone... (so has to be correct)

anybody have any suggestions on how to get this to work now?

thanks
[One (M8) Q&A, Help & Troubleshooting] Einwod:
You only install Sync Manager for the drivers. Once installed, uninstall it again. Reboot your PC and try again. If you want, you can put the device into bootloader mode and run the RUU again.
[One (M8) Q&A, Help & Troubleshooting] xl97:
So now "un-install" the sync manager?

When I connect phone I still get error of device drivers not installed (MTP Driver)

(doesnt look like it did a good job of installing drivers) :(

When you say this: " If you want, you can put the device into bootloader mode and run the RUU again"

I choose that from the (volume down and power button menu?)
[One (M8) Q&A, Help & Troubleshooting] Einwod:
Yes, vol down and power together. On your PC you should also have the new HTC-fastboot.exe file. I have attached it. Extract it and you can rename it to fastboot for easier commands, that's what I did. After doing that, open a command prompt and type: fastboot devices

You should see the serial number of the device in the output. If nothing shows in the output we'll have to change the usb drivers.
[One (M8) Q&A, Help & Troubleshooting] xl97:
downloaded .zip

ran fastboot command.. (returned nothing)

d-clicked on the adb.exe file. then ran your fastboot command.. and am NOW getting a serial number.

What steps do I take now?

Do I try to run the RUU again? Is that what this was in prep for?
[One (M8) Q&A, Help & Troubleshooting] Einwod:
You're ready to go again. Leave the phone in bootloader mode and run the RUU.exe again. Hopefully this time it will flash correctly. If you get the error again (152) start the RUU again without trying to boot the phone.
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
I recommend downloading the RUU again, and trying to run it again. Based the info given so far, there is no reason you should be getting Error 152, unless the download is corrupted.

If it still doesn't work, I'd suggest doing:

fastboot getvar all

And post the output (delete IMEI and serial number before posting). There is more info about your phone that I want to see. Error 152 is odd, and we may be missing something.

[One (M8) Q&A, Help & Troubleshooting] Einwod:
Good man, glad you got it sorted. :good::good::silly: Though surely the contacts and apps should be available thru Google. Or? usually taking the updates should restore the apps, if not they will still show in the ALL section of the Playstore, just download then again.
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
Unless the default was changed, contacts should have been automagically saved to the Google "cloud"; and will auto-restore once the phone is back up and running, and your kid logins to his Google account again.

If email is on Gmail, same thing. But if the HTC mail client was used, then its a different story.

Depending on what other built-in cloud backups were "opted-in" things like photos may have been backed up. Also, anything on the removable SD (if one is present) will still be there.

Take this as a lesson to take advantage of cloud backup solutions (or other backup methods) for all the devices in your house. If the data is important to you, back it up. Waiting to recover data after a disaster has happened, is often too late.

You haven't given us any information to answer that. Describe, in detail, what steps have you accomplished, where exactly did you get stuck, and what is the current status of the device? Screenshot is too small to read much of anything. But what I can see, you're using the toolkit, which is a mistake. TWRP version and SuperSU version included in the toolkit are obsolete, and will cause problems.

You've also posted to 3 different threads, and all those threads have different info (each has a portion of the story, but not the full story). Stick to one thread, and give all the details there. Otherwise its very difficult to follow what you are even talking about, much less help.

I'm not clear what your goal is. I know you want to downgrade, but I see in another thread you posted, you tried to root (which doesn't help your downgrade issue). What is your plan after you unlock the bootloader?

Also, not enough info about your phone. Do fastboot getvar all, and post the output (delete IMEI and serial number before posting).

Maybe the G2 its litlle worse than M8 but battery life is much better on G2 and that's important to me and offcourse big minus on HTC is very heavy to dissasemble their phones and each part looks very fragile for me.

p.s. good luck with the LGG2 , hope its a good phone for you.

and by the way ; if you ever get another m8 and get caught in a bootloop again , you dont have to take the phone apart and disconnect the battery. simply hold the power and volume up buttons till screen goes black ; release those buttons and hold volume down and that will take you to the bootloader screen. just sayin.
