OK I'm going to flash mpd-boost.IMG just to confirm that the black screen is gone for me

---------- Post added at 08:43 PM ---------- Previous post was at 08:38 PM ----------

I can confirm that running Ruu has fixed all black screen issues for me I am on MPD- boost right now typing this which previously gave me the black screen.

I highly suggest backing up data and running Ruu if you have the black screen issue. Also I did Ruu to the 2.16 AKA 4.4.3 ROM for sprint then did OTA to 4.4.4 but I believe that just running Ruu period will solve the issue.

Same here.

I posted logs on the Vanir thread yesterday.
[One (M8) Android Development] schnob:
I'm on Verizon, just RUUed to the latest firmware and all that good stuff. I'll give epsilon a try just for kicks, see if the RUU did something that simply updating the firmware won't.
[One (M8) Android Development] dandan2980:
Hope it works Epsilon is pretty boss too
[One (M8) Android Development] David 617:
Fyi, Epsilon did not work for me
[One (M8) Android Development] schnob:
Did you RUU or just flash the new firmware?
[One (M8) Android Development] dandan2980:
Even after running Ruu?
[One (M8) Android Development] David 617:
Just the latest firmware
[One (M8) Android Development] dandan2980:
Do did it flash for you??? No black screen??
[One (M8) Android Development] schnob:
Still DLing the latest slim to flash, we'll see afterwards.
[One (M8) Android Development] dandan2980:
Run a Ruu but back up data in your internal storage. Move it to your external or save on PC. It wipes the phone clean and installs rom like you just bought it from the store
[One (M8) Android Development] schnob:
We're golden! Verizon users, I would recommend running the latest 4.4.4 RUU, then giving epsilon a try.
[One (M8) Android Development] dandan2980:
SWEEEEETTTT!!!! could have possibly been caused by all the partition fixes that I had to flash because of the previous builds that messed up the partitions.

But then again NV9 was always golden.
[One (M8) Android Development] StarfishP:
So uh. How does one run an RUU. lol sorry for asking @_@

Edit. Just kidding I remember how now
[One (M8) Android Development] schnob:
Thanks for the recommendation man, I was really bummed not being able to run all these awesome kernels.

So you're telling me I should give this fancy new slim governor a try eh? Been a while since I've had any new governors to fool with.
[One (M8) Android Development] Rauch:
Incorrect. Using nv11 and 14 here on 3.18 and new fw from day one
[One (M8) Android Development] dandan2980:
Is amazing governor. It actually reminds me of intellidemand after observing the governor settings. But it send to run smoother than interactive. Also battery life is stellar. Went from 60ish% to 32% with 3 hours of SOT and listening to music for an hour and 45 min basically was staring at phone listening to music most of the time 3 hours straight, lol

I'm on the same exact hboot/os/carrier with no issues. Been running epsilon for 2 days now. That is very odd. Do you guys know how to retrieve your bin info for chip (the pvs number etc.)?

[One (M8) Android Development] droidphile:
Running CM nightlies on GSM M8, no img after nv9 worked for me like many of you out there. However I guess I got an exclusive problem. Because of ocd, I updated firmware by restoring a stock rom and downloading official 4.4.4 update. After that, going back to cm (29/10/2014 nightly) and on nv9, videos doesn't play for me. It's as if there is no video codec at all. (On same nightly and nv9, videos were fine before updating firmware and hboot. Video plays on default CM kernel too)

Hboot 3.19 (updated fw to 3.28.401.7)

International GSM M8

CM 29/10/2014 nightly

Img nv9

Attached is a dmesg grabbed while trying to play a video. Can OP or someone please have a look.

[One (M8) Android Development] StarfishP:
I flashed via flashify. ANd no I do not know how to obtain my bin sadly :(. I'm going to try to flash your zip right now and see how that goes since I did a clean install just now.

Edit: Still getting black screen even with the .zip

Also another thing, I was previously on ViperOne and now on PA. When I booted into bootloader on Viper it would show my OS version, but since switching to PA, the OS version space is blank
[One (M8) Android Development] dandan2980:
Run a Ruu that is for your carrier and it will solve the black screen issue worked for me
[One (M8) Android Development] david.degraw54:
So just run the latest RUU available? And then I will have to root again correct? Also, will i have to unlock the bootloader again?
[One (M8) Android Development] remicks:

[One (M8) Android Development] StarfishP:
I have installed TWRP version 2.8.0.5 of Captain_Throwback and proceeded to flash the zip. I am still getting the blackscreen. I really don't want to RUU my phone and re set up everything so hopefully a solution can be found.
[One (M8) Android Development] dandan2980:
That is the solution. Only take you a half hour to an hour just back up everything to your external SD if you have one or PC run the Ruu and profit. External SD isn't touched on Ruu.
[One (M8) Android Development] remicks:
For what it's worth I have NEVER ran an RUU or FUU on my m8. I have used the firmware zips posted by [MENTION=5317224]Tigerstown[/MENTION] both times (4.4.3 & 4.4.4) and experience no issues with the kernel. I honestly have no clue what's up with this, unless something in the firmware didn't take when flashed.

Spoiler content hidden.
[One (M8) Android Development] dandan2980:
Also the latest Twrp is the official 2.8.0.3 all of CPTB stuff has been merged

---------- Post added at 03:45 PM ---------- Previous post was at 03:41 PM ----------

Actually I ran the Fuu then updated that how I fixes the issue. With the Fuu I just downloaded extracted the 06PB.IMG and put it in the root of external SD and booted to bootloader to like 5-10 min and was done then OTA to 4.4.4. Looks like so.e peeps may need to do this just because one person doesn't have this problem doesn't mean that they shouldn't at least try this method. It actually worked for another user also he did RUU and his black screen is gone. Only thing I can think of is that something has been f'd up and only way to fix is start fresh as of right now.
[One (M8) Android Development] remicks:
Thanks for the input, that kinda confirms what I thought about bad firmware flashes being the culprit of this issue.

From this point forward I will not be attempting assistance for the black screen issue if the user hasn't at least attempted an RUU/FUU to fix the problem, this should help alleviate some of the headaches I keep getting thinking about this bug lol.

Spoiler content hidden.
[One (M8) Android Development] Maestertk:
Yup, I can further confirm updating the ruu fixes the black screen issue. Literally all I did was download captain throwbacks ruu, flash, turn phone on back into vanir, and flashify. Didn't lose any data, system, nothing.
[One (M8) Android Development] dandan2980:
What a minute you flashed thru bootloader??? And didn't lose any data.

Just checked his threads @ MikMik and he has firmware but not any Ruu looks like you may have flashed firmware and not the Ruu but it worked for you good
[One (M8) Android Development] BlackAlien92:
Just flashed on dirty unicorn. So far it works great. I'll b keep testing, also how do you OC?
[One (M8) Android Development] Maestertk:
You're 100% right lol my fault bad wording
[One (M8) Android Development] remicks:
OC is not implemented yet, [MENTION=4003363]xboxfanj[/MENTION] is wary of adding it since not all chips are stable at max clock of 2.8 and he wants stability to be a first priority. That being said, we did discuss this the other night and it is entirely possible at some point that he may build a kernel with a max clock of 2.5ghz. Don't hold your breath for it though.

[One (M8) Android Development] aj8600:
I looked through the forum for RUU files and whatnot and am a little confused. Did you guys flash abck to stock (updated) and reroot your phones? or is there a certain RUU that you would reccomend
[One (M8) Android Development] remicks:
RUU will depend on carrier, I used the firmware zips for Verizon found in that forum. I guess I'm the lucky guy that rooted and went s-off the first time and never had to RUU for anything lol.

Will a couple of the people having issues with black screen please try this:

Run RUU/FUU/firmware update to latest version for your carrier. (MAKE SURE IT'S SUCCESSFUL 100%)

Flash a sense ROM.

Wipe and install a cm/aosp based ROM.

Install epsilon via the IMG file or zip I provided earlier.

Report back.

Thank you in advance.

[One (M8) Android Development] StarfishP:
Yeah that's how my phone is too. Never had to RUU. I flash all the firmware zips fine and am s-off, but this kernel just isn't working for me. I'll probably do an RUU later this week.

The one thing I do notice however is that after flashing the zip and even img file, I go back into fastboot and notice that the OS version is completely blanked out. Can you check if that's the case for you?
[One (M8) Android Development] _moelle:
It was the latest from android-revolution website. 4.4.4 de-odexed....installed through twrp. I wonder that i had to install it via recovery, doesnt a ruu ve to installed through oemRUU? Can someone pls provide me link to that ruu he used? No matter what carrier, just to see if i did flashed the right "thing".
[One (M8) Android Development] dandan2980:
You cannot flash Ruu through recovery it has to be done thru bootloader. You flashed a ROM from what you posted just now. ROM and Ruu are not the same Ruu restores your phone to completely stock meaning everything is the way you bought it from the store.

I managed to fix my problem! I didn't run an RUU. All I did was was reflash the verizon firmware files in fastboot twice in a row.

[One (M8) Android Development] _moelle:
Ok thank you. I really wondered if i flashed tbe right stuff....thought there was something wrong. The main issue is, that for gsm there arent many ruu's available. Was at work yesterday and i didnt find a "real" one. ...but i grabbed one this night, installed it, flashed twrp and flashed vanir + epsilon -> ...black screen! ....i flashed newest firmware right away and got at least to the boot animation of vanir...yeah! But it stucks at that point. ...installed twrp again and reflashed vanir + epsilon -> black screen.

Damn. I think i have to flash newest firmware just after ruuing, right?
[One (M8) Android Development] dandan2980:
Try this what Remicks has posted in that order so yes go to your latest firmware if the Ruu isn't available then I would yes work my way up to the latest firmware

Id also like to report that the new Epsilon kernel doesn't black screen my Verizon m8. I flashed the latest 4.4.4 firmware a few days ago. I'm running the latest CM11 Nightlies. The past few nightlies with Excalibur .5 or epsilon, however, result in video not working for me. Video in youtube or gallery will not playback at all. Funny thing is that if I just flash the CM11 nightly with its stock kernel, video works fine. These Excalibur kernels are a must for me though because doubletap2wake functions flawlessly for me. Cm11 nightlies after 9/15 don't work reliably for me (with threir stock kernels) specifically with doubletap2wake, autobrightness and screen rotation.
[One (M8) Android Development] dandan2980:
Video playback is working just fine for me on elipson.IMG here is a screen shot on YouTube playing just fine I'm on PA based ROM just posted in Sprint android development thread that is all carriers but he posted in Sprint thread cause that's his carrier.

[One (M8) Android Development] _moelle:
Ok guys i think this was all i could try at the moment, leave me move on without me, game over! :D

The main problem at all: there seems to be not only one single RUU out there for gsm HTC_ul/WWE ...correct me pls if i m wrong but i searched the whole web and got nothing^^...so i had to take the RUU of m8_US DEVELOPER EDITION, which is usable aswell on gsm devices. So i ruu'ed the developer edition, (via 0P6BIMG.ZIP on bootloader)...installed latest twrp (same method as ruu) ....fullwipe, installed android revolutionHD 21 SENSE ROM and finally vanir and epsilon.......BOOM LONG TIME NO SEE MISTER BLACK SCREEN, nice to got u back :-/

But to be honest, even if this method work for many people, it makes no sense that this will fix the main problem why black screen appear. ...the rom is booting fine, i just can hear the keyboard sounds after a while, but no screenactivity. Nv9 works fine without all that silly flashing stuff. (Works on all firmwares, just no matter what u are running right now)....so there have to be some setting, done at the development piriod after nv9, that is really bad^^....i thing we gonna be need to find this value/setting and reverse it.
