This one can't for some reason. It fails. It needs to be flashed in fastboot
[One (M8) Android Development] old.splatterhand:
I'm not an expert on these things, but if all things like name of the bootloader zip and the android-info.txt were fine, it worked for all devices i had.

But there are rumors, HTC will encrypt firmware files in coming 4.4.3 and US carriers are a different story at all, so this might not work for all or anymore...
[One (M8) Android Development] Behold_this:
There have been two 4.4.3 otas pushed to the M8 since that rumor was made public and they have both proven that rumor false. Neither contained any encryption. There have been no M8 updates pushed with encryption. The two 4.4.3 otas updates that have been pushed are for Sprint and now the Developer Edition.

There was one update pushed for the developer edition M7 that was encrypted but at this point that is the exception not the rule. There are a number of factors that could have contributed to an encrypted OTA going out not the least of which being a simple mistake.

At this point it seems nothing more than a rumor and there has been good evidence to contradict that rumour.
[One (M8) Android Development] old.splatterhand:
No problem, i only wanted to point out some reasons why the radio.img did not flash in bootloader.

That's why i spoke about "rumors".

model id incorrect

facing some issues when flashing firmware.. it says model id incorrect.. im using an australian htc one m8 rooted and s off
[One (M8) Android Development] ckpv5:
You need to extract out the android-info.txt from the firmware.zip. Then edit it with Notepad++ to add in your device CID and MID (model id) to it. Drag back the edited android-info.txt to the firmware.zip, then try again.

Or you can change your device CID to SuperCID

I am asking again since I received no response..

So let me get this straight that once verizon comes out with the updated 4.4.3 firmware I can use this method without the worry of bricking my device?
[One (M8) Android Development] Clark Joseph Kent:
You will always have worry, and you will always have a chance of damaging your device no matter. Hence why manufacturers state Warranty is now voided when you Mod/Tweak your device from Stock. To ask this is off the edge as, you are the one following the directions and as seen so many have issues following directions. But in theory the method, if outlined would work, if tested first which these methods here have been and you follow the directions. Again the "bricking" lays in your hands....

Bottom-line this is not a fair question of yours....
[One (M8) Android Development] the_rooter:
I understand where your coming from, but from reading the thread and seeing the title as it states: Firmware flashing without the panic attacks, and in the main part of the thread it said something about the not worrying about flashing firmware using adb. Thank you for the response.
[One (M8) Android Development] Clark Joseph Kent:
No worries, I can say the method worked for me, with no issues at all. But I am on AT&T and I did get assistance on supercid'ing my device from the OP, since I am on Linux for my PC. ;)
[One (M8) Android Development] rotchcrocket04:
Woke up this morning and the phone was working like normal, hitting great LTE speeds.

Flashed the firmware you mentioned, everything continued to work fine (though I only tested for about 5 minutes).

Flashed the newest version of Insert Coin, broke again.

Play Store refuses to work at all unless on wifi. Every other app works

mostly

fine. However, I've noticed strange intermittent connectivity with apps using LTE. For example, I was browsing random websites to test, then went back to Google.com and it hung for nearly 3 minutes, then loaded the page. Same with the Speed Test app. While on LTE, the app wouldn't load and open properly (assuming because it was trying to gather LTE/server info). Launched the app while on wifi, turned wifi off, then ran the test and it once again pulled great LTE speeds. It now launches fine on LTE, like it should.

This issue is mind boggling to me. I've noticed things seem to "change" the most after reboots.

I'll reiterate, these are the exact issues I was having with my M7. Could this be network related - that somehow goes wrong after flashing different firmware/ROMs?

Thanks again for anybody following along.
[One (M8) Android Development] DROITURK182:
By chance are you clearing your dalvik and cache before and after every firmware and ROM flash? This is something I always do when going to a new firmware and ROM or ROM update. Plus try booting the phone to your boot loader and go into fastboot, and once it is detected run

fastboot erase cache

That has always helped when switching to new firmware.

[One (M8) Android Development] rotchcrocket04:
Thank you SOOOO much!! I regularly clear Dalvik and cache before ROM installs but never did *after* ROM/firmware installs. I cleared both, then did a fastboot erase cache and haven't had ANY issues since (over two days now, I believe).

I work in IT so the stability of certain apps working are important to me (not critical, but important). This has literally plagued me on and off for the last two devices. I noticed it would crop up for a week or two on and off, then go away entirely. PM your PayPal address, I wanna send you a couple bucks for a coffee or a beer. I know it seems like an easy fix but this was a big relief for me, it's the least I can do. Cheers!

RUU to bring FW up to date and erase phone

Flashed TWRP(mainver fixed version)

Flashed ViperOne, profit.

Running better than ever, phone does not get hot, battery is the best yet. Same as many others are reporting. The problem should only affect those who OTA from 4.4.2-4.4.3 on stock Rom. So using the RUU to update the FW and completely wipe the phone prior to flashing a custom Rom should not cause this problem. I may be incorrect, but based on the info and feedback so far, this looks to be fine.

My phone is running like a beast so far with 2.23 FW and ViperOne.

Why don't you run the RUU, then flash custom recovery and flash your Rom.

I am currently on unlock S-Off Verizon M8 running the original firmware (or pretty close).

Which firmware am I looking for from the links on the first page?

And when I flash, do I look lock or S-Off?

Thanks in advance!
[One (M8) Android Development] skulldreamz:
When I made this guide it was for a different way to flash firmware and I've described that in the op. It's not a guide that's supposed to teach people what firmware they need for their own phones. That's something you need to research first. Sorry but I don't understand your question about s-off.

You can always grab firmware from other threads that point you to what you need and then use the method I've posted.
[One (M8) Android Development] RedBullet:
Sorry types too quickly. In general does flashing the firmware this way affect S-Off or unlocked bootloader? Or it is only firmware for embedded hardware (like radios, etc...)?

I think verizon hasn't updated theirs yet, so I have some time to figure things out...
[One (M8) Android Development] skulldreamz:
You have to be s-off to use this method as it flashes firmware to partitions with the same outcome that it would if you flashed in ruu mode

Download 1 of the zips and open it if you want to see exactly what type of firmware this flashes
[One (M8) Android Development] RedBullet:
Yep, already S-Off, unlocked bootloader and custom recovery.

My question was whether flashing firmware affects any of those?
[One (M8) Android Development] redoregon:
Nope.

I'm going to flash the latest AT&T 2.23 with the assumption of it will not erase data/cache on my device. But still, do I need to re-flash rom after that? (viper 2.4.0/ fw 2.22.401.5)
[One (M8) Android Development] RedBullet:
I am not an expert and I don't play one on TV and I didn't stay at a holiday inn last night...

But if I understand it correctly the firmware upgrade shouldn't affect your system/data partitions.

That being said, do a complete backup. Worst case you would have to restore on top of your new firmware...

Someone school me if I have this wrong...

(waiting for my verizon update tomorrow, so I am interested...)
[One (M8) Android Development] walle4893:
Thanks! My thought exactly. But where do I find the latest fw 2.23 for AT&T? This guy here post a RADIO but im not sure if its the full firmware http://xdaforums.com/showpost.php?p=55117820&postcount=452

but as far as I know the full firmware already contains radio inside its zip file. So basically above it's the actual firmware correct ? (that one is ~ 21mb and the previous ver. 2.22 was 30mb)
[One (M8) Android Development] bruce7373:
No, it's only the radio. I'm interested in the 2.23 fw as well so I don't have to flash the whole RUU to get it. But having the radio is good, so thanks for the link.

Btw, has anyone else noticed better LTE speeds with this radio?
[One (M8) Android Development] skulldreamz:
Something I always check before I flash any zip is every .img inside the zip and also open the android-info.txt to make sure it's compatible for your device. With that said if dzdata is in the zip it will erase your data/cache but dzdata is almost always removed from a firmware zip by the person hosting the firmware. So in short just make sure that is not in the zip and you will not have to reflash your rom after updating firmware [emoji6]
[One (M8) Android Development] walle4893:
Did you manage to pull the latest 2.23 zip? Since upgrading to 4.4.3 Viper 2.4.0 we are strongly advised to update the fw plus some people say 2.23 gives you better signal, boot time, battery and all that jazz
