HTC M8- Developer Won't turn on, some settings are blocked and useless ads - One (M8) Q&A, Help & Troubleshooting

Hello, I recently got this HTC M8 from a friend, and it's really annoying.
Let me start with begining:
1. I got some ads with HTC EYE , HTC BOOMSOUND that distrubs me, they just pop up even if phone is in stand by:
2. I tapped on that build no and made developer optins appear, but they won't turn on( I need to turn them on so I can de-activate the USB debugging. :
3. I can't do some functions for example: I can't choose a lock screen, I can't change brightness and many more things. What is the problem? :
Please help me!
!!! I'VE ATTACHED PHOTOS BECAUSE NEW USERS LIKE ME CAN'T POST OUTSIDE LINKS!!!

Well, if the phone is stock you can perform a factory reset and see if that solves, otherwise you can flash a custom rom and this should solve issue :good:

WTF?! - Extreme colorflickering when touching LCD AFTER htcdev unlock

Hi,
i'm really confused.
I got my One X since it was released and fighted with myself all the time about unlocking the bootloader or waiting for S-OFF.
Now i did the htcdev unlock and flashed the latest unofficial cwm - Nothing more.
After restarting the phone it flickers extremely heavy in all colors when touching the lcd. Wtf is this? I did not install or change the ROM, i',m on the latest official 1.29.xx.11.
This is really annoying as i am really afraid of my warranty now. I think i don't flash any other ROM and just flash the stock recovery back.
Does anyone have the german / wwe unbranded 1.29.xx.11 RUU NOT on filefactory available?
Here is the video of the flickering
After rebooting it seemed to be gone, after a couple of minutes it occured again, but in another way:
Red frame around the screen
What is this!?

It was not checked! But i have to say that i rebooted in the meantime and the issue changed (see main post).
I can reproduce the first issue when checking the setting you mentioned. I noticed that "strict mode" (i don't know the name of the setting in english) was activated. Is this maybe responsible for the red frames?

Make a backup, Install a custom Rom and see if that goes away
Also on Development options DO NOT tick any of the options under "User Interface" except "Force GPU Renering"
edit: nevermind, I should have read your post properly. I've seen the red screen border thing before. No idea what's causing it though. I'd suggest flashing a new ROM to see if that fixes it, you can always return to the stock firmware if you want.
As mentioned in the last post I would highly recommend wiping everything on your phone and then flashing a new ROM. Preferably a new kernel too
Couldn't you just flash back stock recovery and perform the stock format back to factory settings?

One of the developer options gives you red boxes, it could be strict mode.
Tick it, come out of the options, then go back and untick it.
Flashing a Rom seems like overkill for getting default settings when you can just untick the box.
Everything should be unchecked except USB debugging and animations.

I flashed a custom rom now and the red border seems to be gone. I'll watch it
Thanks so far!

Mobile Data drops when screen locked

When ever I lock my screen, my data will drop resulting in me not able to receive any updates from any apps. I use whatsapp and messenger as my main form of communication, and I do not know when people message me as the data drops. As soon as I turn my screen on, the signal bar turns blue, and all my messages comes through.
I have tried reflashing several kernels and ROMS, but they all do the same thing.
Will wiping the SD card every time i flash a new ROM cause this issue? I have tried everything and nothing works.
Please heeelp
Thaanksss
Do you have battery saver turned on perhaps?. Sounds like its set to disable data while screen is off. Power menu in settings should sort you out

Thanks for your reply!
But there is nothing, no apps nothing. I just flashed the ROm and only installed whatsapp.
It still does that. The radio and mobile network works fine so it probably is not a hardware issue.
Battery saver is not an app, its a setting within the power menu, settings/power/power saver. You then have the option to to turn off various things when the phone sleeps. I'm on viperx 3.5.5 but most Roms will be similar to reach the battery saver settings

From your previous posts it looks like you've had this problem in January with a nexus using cyanogen ?. Strange that you have the same problem on 2 entirely different devices, maybe its something to do with the way you're flashing....

That is exactly my worry.
The way i flash is wipe sd card, then flash the kernel via fastboot then flash the ROM chosen.
Now i am not wiping SD card, just making a full wipe. Is there a way to fix this error? I locked and unlocked my bootloader, upgraded my hboot and it still doesnt work. What can i do :3
Don't flash the Kernel first sheesh !!
Do all neccessary wipes e.g. Cache/Dalvik
Flash the ROM.
Boot
Let it boot then back to recovery
Flash Kernel

Not sure if you've already tried this or not, but check this out
go to settings / data usage
flip your mobile data on / off
choose settings, enable Data Roaming, not to worry, your going to turn it off again right away
wait a few secs for it to 'take, then settings disable data roaming, now reboot the phone
hope this helps!

Why don't you try latest viperx, I'm using it and I know everything is working straight from flashing without having to change any settings. Maybe it can help with your camera problem too. If that doesn't help then only option really is back to stock and try get it changed or repaired under warranty and hope they don't notice that its been relocked. Sounds like you bought a bad one though if the camera and radio are faulty.

[Q] Help me in flashing firmware of One M8

hey, guys. I'm new to android. I bought a HTC one M8 used (not totally, it's a phone of a HTC developer I think) yesterday. But it's firmware or android is weird. First I thought it's a clone but it's real. All HTC features are present. But another weird thing was when I updated a new build, a girl named Jennifer showed up like first time on my card & a bunch of contacts saved. In details I found out all of them are HTC developers. So, I think it's a real HTC one M8. It has a demo app which stay open when display sleeps, prevent it from sleeping. Also many settings are locked. Like power saving quick settings, Airplane mode. Also it's in full brightness & both quick setting + main setting is locked. I can see & trap it but don't work. Most of the settings are locked including developer options. It's white & tapping on/off doesn't work. The retailer shop keeper said flashing a new firmware will solve it. But their shop is really far away & I've no ideas on android firmware flashing. I know about Symbian flashing though but that's no use. Please somebody help me. I need a procedure for flashing & link of M8's firmware. My phone is Europe version. & also it'd be nice if you can tell me how can I see or edit my external memory card. Please help. Thanks in advance

You don't know how to take a screenshot? Hold power button and press home button at same time.
Good luck with getting it sorted! Can't you ask the previous owner for help or do you not know them?

Dude, I know how to take screenshots but dunno how to post in XDA. And I thought my phone is used cuz a girl from demo app was set up as user. Then I found out their is a about 700MB zip file with those pictures and stuffs. Whatever, I'm gonna try hard resetting now. Wish me luck
You can factory reset from bootloader or from stock recovery.
To get to bootloader, press and hold power + volume up. Eventually the phone will shut off and the screen will go black. Let go of power and volume up. Press and hold volume down until the bootloader comes up.

How to remove retail mode?

Hi,
I have a galaxy note 2014 edition that has retail mode on, it was a demo ex. Is there anyway to remove this from the device? Maybe through factory reset with stock firmware or something? Have no idea how to do a factory reset with stock firmware if that works.

Hi,
To do a factory reset: Switch off the tablet.
Then power it up by pressing simultaneously and holding : Volume up + Home + Power
When in Recovery mode move the cursor with the volume key and execute with the power key.
Select Factory reset and execute it.

Hi,
OK, the first thing to know is which device you have: Sm-P600/601/605 ??
Then to know which ROM is installed on the tablet ?
If you can go to setting : then scroll down to "About the phone" you should see the version of the ROM.
With that you go to sammobile
You put your device type and you will get all the stock ROM's
You click on the one you want and on the next windows you will have the URL to download and the way to install it.
To be able to download the ROM you have to register on this site but it's free of charge !!

You can try from HERE
But I am not sure it will be any faster.
Those ROM's are quite big > 1.xx Gb so if your internet connection is slow it's take time.

One more question, I can´t seem to set some kind of password for the lockscreen since the lock screen option is gone in some way. It says something about Knox but what is that?
Can i add some other app that handles the lock screen?
About Knox: it's some kind of security introduced by Samsung some months ago, a real pain in the back..
Have a look HERE (for example) for more details.
Yes you can install applications w/o problem.
Knox will only get involved when you start playing with the ROM's, Bootloader etc ..
Hi
Hello guys, I have an Galaxy S6 Edge Demo version, I want to know if I change the motherboard with another with GSM function, it will work fine ?
The digital finger print doesn't work, I have to change the button or how can I fix this ?
And another thing, in the background of display, you can barely notice a text, this : Samsung Galaxy S6 Edge, this thing is from display or motherboard ? Because I want to know, if I change the motherboard, it will dissapear that text ?
Thank you.
I would like to remove the starting screen ''Live demo unit'' on SM-T800X tablet to the stock one, and after flashing I have got the demo pieces of text in the bottom of the screen.
I tried to re-partition the install with ODIN and used a PIT file but no changes. Anybody can help with this problem please ? Is there any solution to change the demo unit to look as a stock SM-T800 ?
Also if there any solution to change KNOX value to 0 would be great.

how to downgrade to android 6

hi
I have an HTC 10 Nougat 7.0 v2.41.401.4
phone is unlocked and S-ON
It's camera stopped working so I googled and I did a lot of work (clearing cash ,master reset , .....)some told it might be a software problem so there is a chance by downgrading to Android 6 and camera might work!
how could I do that?
I'm not professional at this would you please explain with detail?
Is there any official Rom higher than mine(v2.41.401.4 )?

I don't see how that would fix your issue, but in any case the only way to downgrade to 6.0 would be to pay for S-Off first.
You could try running the ruu for your current version and see if it helps. It would restore your phone to a fully virgin state.
I really dont know how could it help (downgrading)but some people who had same problem told downgrading to android 6 helped camera came back!
you mean I download RUU with the my current version and flash it ?

Yeah that's one thing you could try first and see if it helps. Don't forget that it completely wipes your phone so back everything up.

You don't really need TWRP to clear cache.
To do that, you go to setting -> Apps -> Camera
Click on Storage, at the very bottom, there is clear data and clear cache buttons. <You want to back up all your pictures before clearing anything!>
A factory reset will also do the same thing, but that would erase everything on the phone.
Both the steps assume something in the software is messed up, and you are returning the phone to virgin state to start over.
Clearing cache/data in camera app resets the app in case some setting is messed up. Factory reset should restore all settings of the phone to default, get rids of all added apps, etc. More drastic step is to reinstall the firmware in case it is corrupted. You can do that with TWRP if you have a nandroid backup, or use an RUU from HTC.
(I downloaded TWRP for HTC 10 -one file about 30 MB- and after installing through twrp I wiped all cash and after reboot camera came back also with auto focus problem and bad picture quality)
well only it was OK for one hour and after that camera gone!!!
Its a hardware problem
All things done by me was useless !!!
I recommend you send it to HTC support (warranty)
and don not waste your time like me!!!
