Is the One M8 easy to flash ROM's ? - AT&T HTC One (M8)

I have an upgrade available on ATT, looking at the One M8 or the S5. I like to flash stock ROM's that have been tweaked to remove bloatware, and add better battery life. Been using Android phones for years, had the first four Nexus phones ( N1, N-S, G Nex, N4 ), a couple of HTC ( EVO 4G and One X ), and a few Samsung Galaxy phones ( S2, Note 2, S4 ).
My last HTC was an international One X, and man did that phone piss me off flashing ROM's, had to go through all this fast boot crap, and command prompt stuff, and all these extra steps just to flash a new ROM or kernel, and then always had to make sure I was up to date on my bootloader update or something ? Bottom line it was a big pain in the balls, and frustrating.
My Nexus 4 was easy as pie to flash ROM's and stuff, but the battery life sucked. And I currently have the ATT S4, and this phone is locked down tight, no flashing custom ROM's or kernels on this, only root that's it. So I think I am done with Samsung on U.S. carriers for now.
So lets say I get the ATT One M8, I see it can be rooted pretty easily, and a custom Recovery installed ? What about flashing new ROM's ? Is it as simple as just rebooting the phone to Recovery, and wiping data, etc... then flash the ROM zip and reboot and all good ? Or do we have to go through the bootloader and command prompt stuff on this phone ?
Thank you

Depending on how good you are with ADB and your computer Command Prompt, the hardest part to rooting and flashing custom roms would be unlocking the bootloader as you need to take additional steps to unlock it unlike the Nexus line of devices.
But it's a AIO(All In One Toolkit) in the international threads that haven you just click, copy and paste pretty much.
After that all you need to do is install a recovery and flash away. No more need of a computer every time you want to flash a rom like the One X did

Thanks. I understand that rooting and unlocking the One M8 is more in depth and longer process than a Nexus phone, but once that's completed, and a Recovery installed on the phone I just want to be able to download ROM zips to the sd/card, and quickly reboot and flash a ROM and be done. I was really turned off by that international One X crap, flashing a ROM became a major ordeal.

Yup you can just download the rom to your SD card and flash from there

Are the international roms compatible like with the m7

its not hard at all and shouldnt take you more than 20-30 mins. its relatively simple actually.

i just got the att m8 , it has hboot 3.16. i was able to unlock with htc dev, s-off was easy on firewater, but i have not been ablle to successfully flash other roms. the phone will finish successfully but upon rebooting into the new rom, the phone will get to the screen when u chose language then reboot itself every min or so from booting up. i havent tryied to flash any aosp roms yet, i have a feeling that aosp roms would work fine, but i dont want an aosp rom yet. i feel like its a sense thing. i have tryed to change my phone to a developer edition, changed cid to supercid, flash developer nandroid, same problem, i sim unlocked and using tmobile sim card no issues there, but the stock rom my phone came with is the only one that works.

I would go with the M8 I had the note 3 as my last At&t phone and no one was ever able to unlock the bootloader.

Do I really need To Unlock Bootloader?

OK so I have been searching for this and im seeing somethings come up about unlocking bootloader for the photon and that you will lose 4g data. I kind dont want to lol.. But I do want to root the phone and flash some Roms. Do you really need to unlock bootloader to flash roms. Or it depends on the flashable rom that needs to have bootloader unlocked. Im reading about the unlock bootloader and not seeing why I need to do so. Or do you have to do so to flash ANY roms/kernels?
I see in the deve threads about rooting the the photon. looks simple enough which I have rooted others. But just double checking on these methods here. So any advice will be very helpful.
Unlocking the bootloader allows you to write to partitions that would normally not be allowed, even with root - like recovery. I think -though I have never done it - that you can use bootstrap recovery and get the same effect, but it is more of a hassle. Personally theres no WiMax near me without a 20 minute drive, then I can only get it if I am standing still and its no faster than 3G....so it was no question for me.
But I think that you can unlock, flash, and relock and some other steps to keep 4G active.
So you really don't need to unlock bootloader? Cause I'm rooting my friends once he gets in . So in trying to get all the info about rooting. But the 4g data connection will be good as the H huspa/3G is different cause its sprint. Just want to make that unlocking the bootloader is not a must do step. And when I root the photon I'm still able to use Rom manager to back up current roms etc.. and boot into recovery to flash any Rom

You'll have to look at how the bootstrap recovery works - i've never used it. but I think thats the route you need to take.
You can get bootstrap recovery and flash p-roms. They dont require unlocked bootloader.

I think the Laser ROM is the only P-ROM we have isn't it?
Where is that boot scrap at? And I notice not a lot of rons yet for the photon. So most of the roms will or will not need unlocked bootloader. What did u guys do for rooting,.and did you guys use the unlock bootloader.
Cause I seen then the one where u can root with hot the dock using that torpedo set up

Okay, so the Laser ROM which is in the Dev section some place, if you can't find it, I can hunt it down for you is a P-ROM that can be flashed via Boot Strap Recovery and doesn't require an unlocked bootloader.
As for Home Base, Alien, and Star Wars those are full ROM's so you will need to unlock the bootloader for reasons KCarpenter has mentioned.
I personally did the torpedo root method myself, was easy enough if you have a decent understand of command prompt and can follow written instructions, if not, there is also the AIO one click root method that is pretty easy and a lot of people use.
As for unlocking the bootloader, I think there is a thread here, if not, I can post a link that will help.
Also, I included the bootstrap recovery apk in this reply. Hope this helps.
Soon as I get back to my pc I'm thank u and the other member. Where is that aio located so I can that to and yeah I rooted some other stuff before and my inspire.
So might as well do the unlock bootloader and when I do I'll lose the 4g connection but still have 3g though.
What does that boot strap do.and.u need root to load that right..

Bootstrap is pretty much a recovery for a locked bootloader. It works more or less like CWM does on unlocked bootloaders. But...if you're going to unlock, don't worry about Bootstrap, just do the CWM recovery.

No worries Man. If you have any questions, I'll see what I can do to help ya.
awesome deal.. so once I root and then unlock bootloader. Which will allow me to install any roms and have clockwork mod so then I can back up my roms that install.. also where is thread for this where if need to unroot and restore all back to factory like out of the box.
and Im watching that youtube video about AIO root looks simple enough. But also see another video about rooting and unlocking bootloader.. Im still like 50/50 if I should unlock boot loader or not lol
I have been thinking about unlocking the bootloader as well and have chosen not to at this time. This is primarily because there are only 2 custom ROMs in existence for the Photon. We need more ROM choices for me to take the leap even though there is no 4G where I work or where I live.

So really dont need to worry about like as in doing that method(unlocking bootloader) right away cause I only see like 3 roms lol I think. But i was thinking of flashing the Alien Rom seems to be the most popular one out right now but at the same time that needs to have unlock bootloader..
What roms are you guys you using
I'm on Home Base. V1.5 with the 4.2 update. Do you want the green color scheme from the Alien ROM?
Also. There is an overclock kernal which I run that you nees to be unlocked for. There was a stock file floating around. But just flash the latest SBF file. That SHOULD take you to stock. But you would have to ask in thay specific thread.

Is it rough switching devices

I love my epic 4g but am concerned that if I switched to another device I would be wondering all day how to root and maintain it. I love Odin for Samsung but do alot of other companies like HTC or LG have similar programs or will I have to go to night school just to use my phone and flash new roms and kernels? I wouldn't consider myself a complete noob I have rooted my epic, HD2, And mytouch3gslide. Just wondering what to expect as I further my development experience and possibly start making my own roms
Sent from my SPH-D700 using XDA
With HTC devices, you generally use fastboot for flashing a custom recovery, after unlocking the bootloader via the official HTC bootloader unlocking website. Then you can use the custom recovery to install custom ROMs or a .zip that will root the stock ROM.
As I understand it, fastboot is sort of a "universal" tool for Android phones, most phones will have a fastboot mode where you can use fastboot to flash images to the phone (not just recovery, you can also flash boot.img, system.img etc.). It's a command line tool (i.e. you need to open a command prompt and type in commands to use it), but it's fairly easy to use. Generally you'll be able to find a tutorial to root or install custom ROMs, and they'll tell you exactly what to type, or even better provide a .bat which will run the commands for you.
For non-HTC devices, they can often be rooted using a tool like SuperOneClick or UnlockRoot. After they're rooted, provided the bootloader isn't locked, ROM Manager should be able to install a custom recovery and custom ROMs.

Asking for information again.

I just got the new HTC One yesterday, I upgraded from a One X and had that rooted, unlocked , and flashed several roms back and forth.
Is this HTC One like the HTC One X for rooting and flashing custom recoveries?
Another question off this subject. But, is there any way to get rid of the Blink Feed without rooting

I don't know about the One X, but for the One, in general it's: unlock bootloader --> flash custom recovery --> anything you want (root/flash roms & modules/etc)
About the second question: your only option to get rid of Blinkfeed completely is to install a different launcher, but you'll lose Sense. You can also push Blinkfeed screen out of the way by making another screen as your home screen, and just pretend that that screen doesn't exist.

Sounds like the HTC one and the HTC One X is about the same,get token, unlock, flash recovery then whatever on the roms and mods.
I think thats what I did, pushed it over to another screen and don't use it. I don't like having multiple screeens but that is what I have . Guess maybe to get rid of it, is unlock, and flash another rom.
Thanks

To point you in the right direction...
First thing with a HTC is to understand S-ON / S-OFF vs Unlocked / Locked Boot-loader vs Root.
S-ON / S-OFF is Security, and unique to HTC phones.
With the phone S-ON you can still flash a new kernel (boot.img) and flash new ROM's such as Cyanogenmod (and many more!).
With the phone S-OFF you can flash things like the radio, change the CID (Carrier ID) and more, but being unable to S-OFF is not the end of the world.
Bootloader Locked / Unlocked.
With a locked bootloader, you can still gain root, however depends heavily on the exploit and version of android. A locked bootloader is the main restriction on any device.
With an unlocked bootloader, you can now flash custom recoveries (or just boot into them). Flash custom ROM's, and Flash custom Kernels.
HTCdev.com will allow you to unlock your bootloader by following the instructions on there.
Root = Root, i.e. performing commands or having apps perform functions as the systems Superuser (Administrator) account on your device.
You can have your device S-ON, unlock your device, flash a custom ROM, and not be rooted. It's just most custom ROM's ship with root enabled.
Hopefully the above explains (very basically) the differences between a few terms.
And you most certainly do not need to flash a custom recovery in order to install a custom ROM.
Rob
in all honesty
Unless you really really need it to be unlocked I would honestly advise against unlocking and rooting for this device... when i got mine I loved how smooth the original rom was, but being a long time samsung user I was used to flashing anything with minimal impact. But right now this device has 0 development happening and most people who have unlocked and rooted the EU version of this phone have ended up regretting it as there is no way to restore the original eu firmware...
If you do decided to do it please please please make a full backup of the eu rom before hand... and if you do god i think so many members would love you for posting it on here
but in my own opinion I wouldn't go through with the process again...
@torchwolfery we're sharing exactly the same opinion

Hi Guys,
As I mentioned in my brief explanation of the different terms of rooting / unlocking etc.
You can unlock, and root, while still keeping the stock recovery, and stock ROM.
This means you can root the original ROM to use root apps, and have root, but then simply factory reset to go back to full stock (albeit with an unlocked bootloader).
When you unlock your boot-loader the device will do a factory reset, take a backup at this point, by booting into TWRP (but you don't need to flash TWRP permanently onto the phone.
Instead of >fastboot flash recovery recovery.img
Simply type >fastboot boot recovery.img
Your device will load TWRP, allow you to do a full backup, install superuser / supersu.
Once you exit the recovery, your phone still contains the stock recovery.img, stock boot.img, and stock system.
Hope that helps some others before they flash recovery.img (no need!) and then flash an AT&T ROM on the international version.

Phone won't let me unlock bootloader

So I've been unlocking and rooting/flashing phones since the HTC Universal but i'm stumped. I've downloaded the toolkit to unlock my bootloader, downloaded my .bin file and the toolkit says my bootloader is unlocked but the screen on my phone asking me whether i want to unlock it never comes out...any senior members willing to point me in the right direction? I'm using my AT&T M8 on T-mobile and i haven't had a single update since i bought the M8 so i need to update it ASAP.
Update: So I used the sunshine method to try and finally root my phone. Now I'm in the interesting situation where my boot loader is unlocked, it's s-off, yet there is still the stock recovery and not rooted yet. Quite the last 12 hours trying to get root access. I should be able to root it on the PC now that my boot loader is unlocked.

The Toolkit hasn't been updated in forever, is very obsolete, and will therefore cause more problems than anything.
Toolkit just does functions that are easy to do yourself "manually" anyway. You don't need the toolkit, and you didn't need to s-off to unlock the bootloader (although it can be handy for other things).

OTA updates for the AT&T version will only be received when connected to AT&T's network (an AT&T specific annoyance). You could have updated to Lollipop using RUU.

Now that the bootloader is unlocked, just flash TWRP via fastboot. Then flash SuperSU 2.46 using TWRP to obtain root.
But your OP says you want to update. Here it says you want to root. Those are 2 very different things, so its not clear what your actual goal is.

Thanks for the help and sorry for the confusion.
I'm looking to update my phone AND root just because I've always rooted my phones but just now got a replacement for my old laptop that broke down shortly before I got the M8. I figured since I was on T-Mobile my best bet to update it would be to root it and upload a new ROM anyway. Your suggestion is easy enough so I'll be doing that after work.
My last question is this: On the M7, I was able to use an international M7 ROM as everything apart from the radios was the same. Is that the case with the M8 as well? I typically like having Sense ROM's but hate the bloat carriers put on their RUU's....
thanks again!

In that case, I would suggest updating by RUU first, and then root.
Reason I say that, is that RUU would wipe out root anyway, so no point in having to do it twice.
Whether you unlock the bootloader (via HTCDev.com) before or after RUU is somewhat irrelevant. Especially since you have s-off, so its not required to relock the bootloader to RUU (which is required with s-on).
But one other thing to consider. Since you are using the AT&T version on the T-Mobile US network; the ATT version is actually missing support for the AWS band that T-Mob uses in most areas for HSPA (3G). If you are in an area with good LTE coverage (and I'll assume NYC is) you may have not even noticed this. But if you move into an area where T-Mob doesn't have LTE, you might find that you don't have 3G either, and be pushed down to 2G (EDGE) data speed.
One cool thing about the M8, is the band support is actually software based. So one option would be to change your device's carrier ID (CID) and model ID (MID) which are possible with s-off, then flash the T-Mobile firmware or RUU to "convert" the phone to a T-Mob device including the proper T-Mob band support. After that, you can unlock the bootloader, root, flash a custom ROM.

Yes, its a similar situation on the M8. All international ROMs should work on the M8. But note that your firmware (hboot, radio, etc.) needs to be the proper version supported by the ROM. So for instance, if you are still on KitKat (sounds like you are) you will want to update firmware first, otherwise if you flash a Lollipop ROM, you will likely suffer major issues such as broken WiFi and extreme long boot times (10+ min).

I gave previous advice to stop using the toolkit, so I don't know why you insist on ignoring that advice.
Older versions of TWRP don't work on newer hboots; and the opposite is true where older hboots don't work with newer TWRP builds. This is the most frequent reason for TWRP not working properly.The toolkit worked fine at the time it was updated. But it hasn't been updated in a very long time, and therefore won't work on many M8 versions now. The issue is more your lack of understanding, and lack of following advice given to you.
Flashing TWRP is just a matter of downloading the proper version, and flashing with a single fastboot command (2 commands, if you want to be thorough and wipe cache before flashing TWRP). You don't need a toolkit for that, and again I advise stopping its use altogether.
Its not clear whether you chose to update before TWRP and root (current device status) and once I know the main version (OS number on bootloader screen) and present hboot number I can probably advice what version TWRP you need to flash.
And you're absolutely right about that. It was my fault for not listening. I was being lazy about it honestly.
I did end up using the lollipop pre rooted RUU and that worked after two atttempts. I think the issue was that the toolkit flashed the recovery without root. Add that to the fact that the toolkit caused the SD card issue to pop up made it a nightmare. Thankfully, I was able to fix it and now I'm running the AT&T lollipop ROM rooted.
You truly are the best and I thank you for the advice and help. Let me know your PayPal so I can send you beer money for the trouble.

I don't follow. Root isn't needed to install custom recovery; nor does flashing custom recovery automatically root the phone (this has to be done as an additional step, usually by flashing SuperSU in TWRP).
I think the main issue was that the toolkit flashed an old TWRP version that was not compatible with the software/firmware that was on your phone.

I appreciate the thought; but your thanks is all I expect in return. I've benefited plenty from XDA from folks that don't ask for any monetary compensation; so I just like to give back to the community by helping how I can.
