So you came to find help with your HTC One M8?Well, this is your thread!

I was surprised to see that a help thread hadn't been created in this forum yet (especially considering it's usually one of the first threads created in a device forum). Due to that, I thought it would be a good idea to set this up :)

Hello new user and welcome to XDA-Developers. We are a developer’s forum, with the purpose of development. Our work can be used in several ways, and, we know that sometimes it could help you. So, in order to maintain our forums clean and properly organized, maintaining a proper development environment while at the same time to give you a chance to join our forums, we created this thread.

This thread is for sensible questions from new or inexpert users. If you think your question may be a little basic for the wild Q&A forum then this is the place to ask it.

Here you shall find an atmosphere free of prejudice, where we will try to help you in your problem, answer your most basic questions and aid you on troubleshooting your device. We know that learning all the technicalities takes time, however they are necessary in order to interact with us.

Bare in mind that we are not technical support, we do not work for any company or get paid to help, we are just independent developers gathered in a community called XDA-Developers. Therefore all we will do is guide you into troubleshooting your device yourself, but under no circumstance we are abided to do so.

We want you to become the kind of user we see as productive to a developer’s community, and why not?, to be a developer yourself!

Note to General users:
This is a chance for more advanced users to “give back” to XDA-Developers the knowledge we have gathered together in a decade of development. This is a thread to behave in a tolerant way, taking into consideration that the user posting queries might have never even heard words such as “adb” or “ROM", so, if you are not willing to be helpful, I kindly invite you to browse into another thread.

Before asking a question in this thread, I suggest reading through the HTC One M8 Frequently Asked Questions as it's possible that your question may have already been answered in that thread :)

Moderators will not tolerate "flaming" or "trolling" in this thread as it is specifically provided for those who are still learning the basics.. We will delete and sanction without warning any post that show intention other than to help the new user.

As you may notice, I kanged this thread layout from @D.O.C from the M7 help thread. Thanks sir ;)

SIM card and IMEI issues after converting to GPE

Hello everyone!

So I just bought an asian HTC one M8 developer edition from a friend and I wish I couldnt be more happy, but Im facing some issues and I hope you could help me! :eek:

I converted my HTC dev to a GPE by flashing the RUU. Before that my SIM card and network worked just fine.
But now my baseband, network, IMEI etc are all shown by "unknown" and dont work.

I actually found a forum where someone had virtually the same issue: http://forum.xda-developers.com/general/help/urgent-help-required-htc-one-m8-sim-t2810468
But while he was able to fix it by flashing a radio image of his device's original CID, that same image doesnt appear to be available anymore! (i have the same original CID as the case mentioned).
http://forum.xda-developers.com/showthread.php?t=2736921

Right now I have super CID (11111111) and my radio shows up as 1.14.21331931.LA02_2G

my original CID was BS_US002

Does anybody knows if i have to find and flash my orginal's CID radio image, or is there any other way around...

Please help me guys! xDD
thanks in advance

@rafael.trad From looking at the OP of the radio thread, there's a couple of files showing under BS_US002 (quoted below):


Have you tried either of those 2 yet to see if it'll fix your issue?
I have tried them. But those two files are actually the only ones I can't open.
When i click on any of them it opens a Dropbox page with an error (404), saying that the files are no longer there. =/

I probably should've checked those links before posting that ;)

Try the following dev edition radio posted by donmarkoni - http://www.mediafire.com/?7i0jz8axi77ic06

Hello guys. I've been googling around why I can't root or unlock boot loader on my HTC one model id 0P6B12000. BS_US001 from what I understand it's the at&t dev edition. I've tried everything from towel root to sunshine to HTC dev unlock. Nothing works. Root fails, sunshine reboots, HTC unlock token is successful but does not unlock. Fastboot oem unlock returns err. Any ideas? Am I missing something?

Yeah, I'm getting the same problem. Flashed the unlock token and I unlocked the bootloader, but when I reboot into fastboot, it still says it is locked.

HTC Sync Manager

Sorry if this has already been asked somewhere, but I couldn't find an answer.

I have ViperOne up and running on my phone. Since I loaded it, HTC Sync Manager canont see my phone. When I plug my phone in, Android File Transfer Tool opens.

I saw another thread where they said you have to turn off fast charging. That leads me to another potential issue. The guide for ViperOne says that option is under kernels. The only thing I have listed under kernels is "Apply Kernel Settings On Boot." I don't see any of the other options.

Htc one m8 without OS trying to install viper

Hey XDA'ers

few days ago I tried to reset my phone to stock settings and I had stock Rom and everything on except it was rooted and I had twrp on it.
I accidently wiped everything on my phone including the OS itself and thats what you call having a soft bricked phone i think
cause I can still turn in on and enter Bootloader and TWRP.
so I looked everywhere on the internet for the Stock Htc one m8 OS ROM and found nothing at all but lookalikes etc so I searched through some the ROMS and found viper. I have downloaded ViperOne and put it on my SDcard i dont know if im supposed to have S-off to use viper ? or if im supposed to have stock OS and apply Viper to that ? but after successful installation it Reboots and enters Bootloader instantly everythime i turn it on I used to have to turn phone on and hold power button plus volume up then down to enter bootloader but now it just goes straight into that. ive wiped all data chache everything except SDcard
many times and tried to reinstall viper after deleting everything again but with no luck

i have Ruu for my model but my pc doesnt recognize my phone and i have tried sideloading stock rom and GApps but my phone still boots into bootloader when i turn it on

i will apreciate it alot if any one could help me since i have no other phone and my Htc one m8 is pretty new
Thanks in advance

help

i created a thread already, but I dont think it's garnering much attention.....I wouldnt even know where to begin to search for what im searching for, so Ill ask here....I have an AT&T M8. i have the latest baseband (3.28.xxx.6).....everything up til this point was working fine. I had vanir up and running, but after downloading MaxiumusHD and the ota manual update. i wanted to try something different, so I booted into recovery and attempted to wipe everything when I started getting red error messages. Im using CT's latest (non-multiboot recovery). Ive seen these red errors before, so i attempted to flash MaximusHD but b4 it finished the aroma installation, it booted automatically into the htc white screen. Currently I am able to boot into bootloader, and I can bring up fastboot devices and see that my computer recognizes my device. Everytime Ive tried going into recovery to wipe, it autmoatically boots into the that white screen without finishing the wipe process....Im using Hasoon's all in one toolkit so i dont have a computer android sdk package......Does anyone have any idea what I did wrong, b/c I have literally flashed hundreds of roms in the past and never once had this red error message when trying to wipe data in preperation for a rom flash......Right now my phone is in bootloader mode, fastboot usb...

I'm not 100% sure on this, but someone might be able to back me up. ViperOne uses the existing ROM when it installs. I don't believe that ViperOne is a full base OS. I don't know enough about the backups to say if you can use the backup off another phone or not.

If you unlocked your phone, that means you registered with HTC as a developer. You could ask them for the bad OS. I'm not sure if they will give it to you or not. It's at least worth a shot.

Got a new HTC one M8 from Verizon. S off, unlocked, rooted. Everything was working fine until tonight. Did a nandroid backup then installed an Xposed module (advanced power menu) and things started getting funky. Android system ui started force closing so using TWRP attempted a system restore. After a few minutes the restore completed so hit the reboot button. An error message came up and said "appears that device is not rooted, slide button to restore root". Root restore failed, device rebooted and white screen with green HTC logo and powered by ANDROID on came up. Phone vibrates then stays on that screen indefinitely. When I powered off using power and vol up buttons, powers down then immediately reboots and white HTC screen comes up. Can't get it to do anything else. Tried Squabbi's HTC toolkit to send fastboot / ADB reboot commands but wouldn't work. Any suggestions would be appreciated.

Viper, like all other ROM's, is a complete OS on its own. Partitions are another story, but usually not relevant to the average flasher except for an occasional firmware update.

Hi guys,

I've had my M8 for a couple of weeks now, and I love it. I haven't even rooted the thing yet, which is very surprising for me!

One issue I have with my phone, is the music app by HTC is frozen when I launch it. It does not force close. I have tried wiping data and cache, to no avail. It may be unrelated, but my phone doesn't sound too great when plugged into my speakers - maybe the EQ is frozen also. Sounds very virtualized, like I'm in a massive hangar.

I'm on 4.4.3, EE in UK. Thank you!

Sent from my HTC One M8. Long live the Galaxy S3 and S. Those forums will be missed!

Please Help Soft bricked HTC one M8 Sasktel(Canada)

Can someone Please help? I tried to flash custom ROM and erased everything. Only thing I can do now is get into boot loader and Flash recovery. Won't let me flash any custom ROMS. TWRP just aborts the install and won't install. CWM states that md5 file not found and then stops installing.
Here is what my boot loader getvar all states. (See below)
