Like alot of other people, my phone did not recognize my sim card / no signal or data on 1-28-15. I am dev converted running latest firmware.
[One (M8) Original Android Development] Hybridnoob:
To balance things out, I'm on 1/28 and have no SIM/data issues. LTE works fine. I'm running the latest GPE firmware.
[One (M8) Original Android Development] SiK TL:
i posted this exact same issue on the BlissPop thread. They use the CM12 base but never got a response. I have since converted to dev. edition and upgraded firmware. No issues yet. I would have to register my network after every boot and no signal was picked up after clean installs. Hope you get your situation figured out. I really like this rom when its running smooth.
[One (M8) Original Android Development] explode1991:
Do you mean the ATT dev edition? What is your MID and CID? I fixed mine to the point that I can use CM11 again im just curious, I will post the fix here in a minute or so.
[One (M8) Original Android Development] SiK TL:
I'm on T-Mobile but used the same method. I'm running BS_US002/0P6B12000 4.16.1540.8

Im Android Revolution HD 34.0 only cause I'm scared to flash a CM12 based Rom and have that happen again. It's easy to RUU if it did. But it's too time consuming lol
[One (M8) Original Android Development] ErbyTux:
How did you fix it where you can use CM11 again? I can't even get that to work.
[One (M8) Original Android Development] explode1991:
Alrighty for those of you who said you cannot get a signal/IMEI/Baseband in the ROM on CM11 or CM12 after updating to the newest firmware (at least to HBOOT 3.19, cant comment on 3.18), I have found a fix to at least use CM11 again without downgrading the HBOOT. All I did was downgrade my radio, details below:

THIS REQUIRES S-OFF, NO WAY AROUND IT

I was kicking myself for not doing firewater when I still could but oh well, if you need s-off use the sunshine method. Its 25$ well spent (at least for me). Sunshine will only work from a stock ROM, so either restore a backup or download a nandroid from somewhere on xda.

HOW TO FLASH

This will only work for ATT users (MID 12000 and CID CWS__001). I honestly dont think its affecting anyone else anyways. If you wish to confirm your MID and CID type the following in fastboot:

fastboot getvar all

You are looking for model-id and CID.

There are a couple ways this can be done but I'm just gonna post how I did it. First you want to download the old firmware package from this thread:

http://xdaforums.com/showthread.php?t=2696282

The folder you want is 502 and the zip you want is 1.58.502.1, this specific zip is an older firmware package for ATT M8.

1. Extract the zip to a folder, you will see a bunch of img files and an android-info.txt, for funsies you can open the txt to confirm it is for MID 12000 and CID CWS__001

2. Select the "radio.img" and "android-info.txt" and zip them with winzip/winrar/whatever just make sure its a zip. Name it whatever you want.

3. Put your phone in fastboot and open a command window in your fastboot folder.

4. Type the following, remember if you do not have s-off this will not work. It wont brick or anything it just wont work:

fastboot oem rebootRUU

This will put your phone in RUU mode, wait for the HTC logo to show with a black screen

fastboot flash zip *name.zip*

Obviously replace "name.zip" with the name of the zip you made, make sure to complete the next command or the process will be incomplete and you might screw up your radio, beats me. Just do it.

fastboot reboot-bootloader

This will put you back into bootloader, after this go into recovery and install CM11 with gapps. I tried to use CM12 with this radio and although when initial setup started the signal bar was working the OS crashed immediately after setup and after some bootlooping my data got corrupted and I had to format it and push CM11 from inside TWRP, so dont try to use CM12 with this radio (at least not the 1-28 nightly, install at your own risk).

This will put you on an older radio (ill post the version if anyone really wants it) and you will still have HBOOT 3.19. If you want to downgrade the ENTIRE firmware simply flash the zip that you downloaded from the thread I linked; without removing anything; in the same fashion I described. If you wish to downgrade the firmware entirely without removing your custom recovery remove the "recovery.img" from the zip first.

Hope this helps!!!!!

*Please thanks me if this helps, I have been lurking xda for many years and this is my first contribution to the community*

Anyone else getting a horrible 10 second delay when opening apps? Running the latest nightly with the latest lollipop firmware?
[One (M8) Original Android Development] LeVvE:
Nvm.
[One (M8) Original Android Development] ECloud7:
Thanks for this tutorial I hope it will work. I will probably try this weekend. Do you have any idea why it won't work with CM12? Did you happen to try flashing CM12 straight over CM11? I wonder if that would make a difference.

Also when you said you can downgrade the firmware as a whole would that move me back to bootloader 3.18 or 3.16. The only reason I took the over the air update was to change the bootloader to 3.19 from 3.16 so it would be compatible with CM12. As I understand it 3.18 and .19 are both compatible with CM12.
[One (M8) Original Android Development] explode1991:
Honestly I want to say its 3.16 because my radio is now something like 1.12 but without flashing it myself I'm not sure, I have a hard time finding any info correlating firmware versions to hboot and radio versions. I don't think dirty flashing will work for a couple reasons. The radio is independent of the ROM itself which means that no matter what ROM you use or install your radio will not change unless you change it yourself or get an OTA firmware update from your carrier. The other reason is that I BELIEVE that you cannot dirty flash cm11 to cm12 because its an entirely different android version and the left over user data would just confuse it and cause major issues or just stop it from booting altogether.

If someone who is running cm12 on ATT with working cell signal could tell me what radio version they are using and if its GPE or whatever I would love to test it on my phone. Heck just pm me if so inclined and I'll tell you how to extract your radio to send it to me. I really want to get cm12 running on my phone its just too nice to wait for.
[One (M8) Original Android Development] MacFett:
The sound modes in cm12 are frustrating. I can seem to get loud, blow my speaker loud, or vibrate. No silent mode unless I sacrifice my alarm.

Is silent plus alarm possible?
[One (M8) Original Android Development] ECloud7:
Got it got it. Thanks for figuring all of this out! I will probably just hold off on cm11 or 12 for little while longer and see if they release an official fix for all of the radio issues. Why must you do this to us ATT?!
[One (M8) Original Android Development] explode1991:
I don't think its ATTs fault (I only say I think because it shouldn't be since it works fine if you use stock). CM11 still runs fine on the old radio.
[One (M8) Original Android Development] foamerman:
Hey got a question for you guys I'm having trouble with themes all the CM12 themes I've installed say they are there but when I go into themes the only one in there is the default anyone having that trouble and if so how do I fix it? Or is it just me? O clean install and when the new nightly comes out I will do another clean install
[One (M8) Original Android Development] krazie1:
Swipe from the left in Theme Chooser and choose "Styles" they will all be in there
[One (M8) Original Android Development] Fenny:
So, I have been able to reliably reproduce the issue with no audio immediately after connecting to A2DP bluetooth speakers.

It only happens when the audio volume is artificially raised after a notification. (There is also noticeable audio distortion after a notification.) Changing the volume up or down not only fixes the distortion, but also will prevent the issue with no audio from bluetooth devices. I suspect that the volume is being set to too high of a value after a notification finishes. I also noticed that the volume does strange things at around ~80% when connected to bluetooth speakers.

In short, if you change volume up or down just before connecting to a bluetooth speaker device you will avoid the no-sound issue.
[One (M8) Original Android Development] SpaceCadetWilliam:
I'm having this same issue. you can fix it by selecting 'themes', but that just seems like a quick fix because before I could see all my themes and what they included on the home screen. now when I get a new theme I have to go through each option to see if my new theme has new fonts or wallpapers etc.

hopefully this is fixed and isn't a new feature...

ps I love cm12 and am having such a beautiful time with it. I love the themes and tweaks I can make while still remaining as close to stock as possible.
[One (M8) Original Android Development] john_matrix:
Hello!

Are the HTC applications (Gallery, Camera, etc...) working on CM12?

I would say, can we install them from Play Store?

Thanks!
[One (M8) Original Android Development] foamerman:
Yes they were there Thank you :D
[One (M8) Original Android Development] Bobbi lim:
Try to install HTC service pack and install those app. It may work

Is there any issues with the latest CM12 nightlies?
[One (M8) Original Android Development] SpaceCadetWilliam:
I just updated to the latest nightly and everything seems smooth except one random thing, my home button fades away when I pull down the notification tray.

is this a setting I can change? it never did this before.

edit: I changed my dpi and had to reboot and that seems to have fixed the issue.
[One (M8) Original Android Development] msshalim123:
Is over loud sound fixed ??
[One (M8) Original Android Development] lotusboi:
So the sim card issue is gone now?
[One (M8) Original Android Development] farru503:
Viper4android is the solution, you know it
[One (M8) Original Android Development] ECloud7:
On my device the sim card issue is not resolved. Explode1991 created a work around so that CM11 has cellular connection but CM12 still does not.
[One (M8) Original Android Development] carman594:
Sorry to be the noob but are there installation settings for this? It's been awhile since I've done flashing on a phone, lol. Probably since my One X.
[One (M8) Original Android Development] Darknites:
It's the same without the fastboot boot.img bit.
[One (M8) Original Android Development] carman594:
Not sure why I said settings. I meant installation guide.
[One (M8) Original Android Development] sheva7_:
sorry guys, i have a problem.

I have c.m. 11 (2014.11.30) and i would like to install new c.m.12.

After i download the new nightly, i try to install but i wrote me "failed" and i can't install.

I haven't wipe anything but only tried to install the new nightly like other people on the web...

Can you help me?

Do you know which could be the problem??

thanks you very much
[One (M8) Original Android Development] ECloud7:
Do you know if you have bootloader 3.16 or 3.19? When I had trouble installing cm12 that was the issue. CM12 requires that you have bootloader 3.18 or 3.19
[One (M8) Original Android Development] sheva7_:
i have hboot 3.16.0.0000

you think this is the problem?

And, how can i update hboot?
[One (M8) Original Android Development] 3's&7's:

[One (M8) Original Android Development] Rouz.:
I always hated that thing on One X
[One (M8) Original Android Development] Darknites:
Same here but on One S.
[One (M8) Original Android Development] ECloud7:
So updating Hboot is something I struggled with about a month ago when CM12 first came out for the m8. So there are two options to update the hboot. You can either turn s-off which allows you to flash new firmware (including the bootloader), or you can go all the way back to stock, take the latest OTA update and then reload your custom recovery and flash CM.

The old method to turn s-off was with a program called firewater that you sent to your device via ADB. Firewater however no longer works and is no longer supported by the folks who made it. Now to my knowledge the only other method is through an app called "sunshine" which can be downloaded on your device. However it costs $25 to turn s-off but should work (I haven't tried it myself). Once you have s-off you can search for and download the 3.18 or 3.19 bootloader and flash it to your device.

The method I used (Since firewater didn't work) was to return my phone to 100% stock Sense 6 and take the OTA update. In order to get an OTA update the recovery also has to be stock. Here are a couple of links that I followed on how to do this: http://theunlockr.com/2014/06/08/how-to-unroot-the-htc-one-m8-video/

http://www.andromods.com/download-files/htc-one-m8-stock-recovery-verizon-sprint-att-tmobile.html

Once you take the OTA update you will have android version 4.4.4 and Hboot 3.19. Now I thought after doing this I would be fine and dandy but there is ( of course) a problem. So once I had the OTA update I changed the recovery to TWRP and then flashed CM12 with the 5.0 Gapps. CM12 booted and worked fine except there is no cellular signal. It turns out CM12 cannot communicate properly with the most recent OTA update radios, causing CM to think that you do not have a sim card installed.

There is currently no fix for CM12 with the most recent OTA firmware that I am aware of. This is a very recent issue (as of Monday when the OTA was released) so there isn't anything that can be done to fix it yet. I am following the official CM12 thread in XDA closely to see if anyone has a fix or if CyanogenMod releases a new nightly to fix that bug.

Hope this helps!

Found that skydragon kernel may fix the cellular issue. I will hopefully flash today and test for myself!
[One (M8) Original Android Development] ECloud7:
EDIT

Skydragon kernel did not fix the issue in CM12
[One (M8) Original Android Development] explode1991:
Didnt work for me either, same as you said CM12 wouldnt even boot with it installed. I will be reverting back to the old radio and CM11 for now =(

Edit: Lots of weird stuff going on with my internal storage, flashed CM11 M12 but gapps wasnt readable so I repushed thru adb in recovery and then the CM11 zip was gone but I was able to flash gapps. Boot into CM11 and both zips are gone. Reaaaalllly weirding me out.
[One (M8) Original Android Development] SpaceCadetWilliam:
hey gang, so after the update to the latest nightly everything was fine but now I'm experiencing the lock screen issue again.

when I type in my 4 digit number code no numbers appear when I type, yet it unlocks. but after about 4 or 5 unlocks it will stop unlocking and I have to reboot to get access to my phone.

it is strange because once I updated everything was fine and it only just started again now.
[One (M8) Original Android Development] lotusboi:
Is flashing older cm 12 builds working with the sim?
[One (M8) Original Android Development] ECloud7:
No it wasn't. I tried a couple different builds and it didn't work. What you can do is flash the skydragon gpe firmware for all versions of the m8 off of their website. First flash cm12 and let it finish installing and boot up, then go back to recovery and flash the kernel. Cellular works now but video playback is spotty as is WiFi. As of right know that's all I know that works for the cell signal.
[One (M8) Original Android Development] DavySprockett:
Is there a workaround for this, by chance? Wifi is completely disabled for me.

Anyone notice a very long boot time in today's nightly? Also whenever it first boots and I unlock the screen I'm greeted with process system not responding. After that it takes a long time to get data, but after that its fine.

Blows my mind that CMhas hardly any issues. They turned down investment from Google that would have valued Cyanogen Inc @ $1b USD and JUST accepted $70m from Microsoft.

Not sure why ppl are having problems with this ROM. I just installed 1/31 and I'm having zero problems with major functionality. Bluetooth, WiFi, Mobile network all working great. What's interesting is that I'm running a sense/lollipop firmware that's from a Chinese port! So far so good... However, I'm getting frustrated because I can't figure out how to get the mic on my keyboard! Do I need something installed?

Edit: No sound distortion yet either on Pandora or phone call using BT. Will test speakerphone on call next.

[One (M8) Original Android Development] ArtificialMusik:
Can anyone test and see if the bug in which upon reciveing notification or audio from any outside source (ie, navigation prompts, bluetooth pairing requests) if the sound suddenly becomes heavily distorted and sounds as if it's breaking the speakers? The last nightly I've flashed was from 1-29 and the issue presisted. Just asking because I'm at work right now and can not test myself, and would like to know if the issue has been addressed.

---------- Post added at 10:53 AM ---------- Previous post was at 10:49 AM ----------

The issue was not that devices could not be paired, the issue was that devices would simply malfunction after a while or upon connection ((where device is paired, and the guest device(aka, car system, bluetooth headphones) is being turned on))

It could be replicated very easily and seems to do something with the default music player. My guess is a driver is crashing when the default music player crashes and does not automatically reboot itself. To fix the issue, the user needs to completely reboot the host device(phone) to make the bluetooth reconnect and function properly, until the default player crashes again.
[One (M8) Original Android Development] Macke93:
I havent got any of this problem with 31/1-2015 nightly like I said in an earlier post, some bluetooth issue is resolved since 30/1 nightly and it's hopefully solved this problem for those who had it. :)

My phone never gave any sound to my Bluetooth headset or Bluetooth car stereo, it wouldn't even if I rebooted my phone. I used Spotify as music source if that matters, haven't tried any locally stored music trough stock music app :)

My issues with Bluetooth is now gone, so those with similar problems can try if latest nightly solves the problem. :)
[One (M8) Original Android Development] Krunk_Kracker:

Here's the skydragon kernel I used. "https://www.androidfilehost.com/?w=files&flid=14906

I flashed cm12 with gapps and let it boot and setup then went back to recovery and flashed the kernel. I used the kernel from January 28th and it's working alright. WiFi doesn't work but cellular does and that was my main concern.

---------- Post added at 12:24 AM ---------- Previous post was at 12:09 AM ----------

So when you guys say you don't have any issues with Cyanogenmod 12 did you come from hboot 3.19 and the latest ATT firmware version? I updated from the OTA on January 23rd and flashed cm12 and the cellular didn't work. All nightlies through the last one I flashed version 28 all read no sim card. The skydragon kernel let me connect to cellular but not WiFi.
[One (M8) Original Android Development] Rescue9:
This seems to work initially, but after about a day the phone goes wonky. The person on the other end can't hear me at all about 30 seconds into the call. If I don't try to install viper I don't have any problems.

That's a GPE kernel you linked, is that what you meant to link?

So what are the run down of the latest bugs in the newest nightly?
[One (M8) Original Android Development] Krunk_Kracker:
I went ahead and tried the most recent nightly for the Skydragon kernel and my touchscreen would stop working once it booted the Aroma installer. I could sort of navigate with the volume keys and power, but wasn't able to proceed with the install.
[One (M8) Original Android Development] 3's&7's:
Kernels...

Should us CM 12 users steer clear of any Kernel that does not specifically state "CM" on the description? In other words...can GPE be enough of a go ahead for us?

I am totally new to flashing kernels on the m8 (outside of nexus / oneplus).
[One (M8) Original Android Development] lotusboi:
I just flashed cm 12 on my phone without flashing any kernels and the wifi and sim issue is still there.

[One (M8) Original Android Development] polaric:
It seems that the new 02/1 nightly still has the weird bootup issue for me. I've narrowed it down to the system process hanging on boot, for roughly 30 seconds. It also takes it a very long time to pick up data once its booted when before it took seconds. Anyone else getting this?
