Convert At&t HTC One M8 to developers edition - One (M8) Q&A, Help & Troubleshooting

Hello XDA members, before I explain the predicament that I found myself in. Let me first start off by saying, I am a Noob at its earliest stage, and with that being said please be patient with me. For I might sound like I don't know what I am saying or doing. I hope to grow as an XDA member. That way I too can help somebody that maybe in the same situation I'm in one day.
Ok. I have a rooted At&t HTC One M8. Unlocked bootloader and S-off. I was once running TWRP (the best custom recovery imo), switch to Philz, and lastly I am stuck on a weaker version of CWM. I didn't make a nandroid backup of the original kitkat rom. So I am stuck currently running a stable version of ViperRom, keep in mind that it is a kitkat version since I never updated the original software to lollipop. I would like to ask for help from the awesome XDA community to ultimately get my M8 to run as a developer edition with root, get back on twrp, and last but not least find a way that I can flash Sense 7 marshmallow with working radios. I've seen plenty of videos on how to do this. But always come back in a circle to step one (Due to me being a super Noob). I am afraid the way I keep foolishly putting my faith on video instructions, I will one day brick my favorite android phone. I once saw in a comment the best way to get help for tinkering android phones is to be a part of XDA. Please my fellow members help me.

wow this is hard

coming from other android phones that i always was able to flash new roms,i find that reading the threads it seems a lot more complicated ,one thread saying do it this way ,another saying that way ,i dont know where to start,i would dearly like to flash a custom rom because i dont think T MOBILE will ever update[they could not even get the color phone i wanted,they said yes white ,they sent me grey].
is there a step by step instruction someone could point me to,i would be ever so greatfull
Coming from motorola droid 1 and gs2 this is definitely more work. I'm waiting a couple of days before I put cwm, make backup, root, and try roms.

Did you buy the global version and drop a tmo sim into it? I'm with tmo and only the S is available. I've been reading and hoping tmo makes this their next flagship device with the vanilla rom. I want this phone but dont want to pay the 300-400 for it.

He is using international version TMO UK. The phone is pretty new also as time goes by rooting tools will become simplified. There is an all in one tool in dev section.

This is the method I followed step by step. Coming from htc Hero the rooting method for the One X seemed complicated for me too but after a few attempts I managed to get it rooted and flashed successfully.
Just don't forget to flash the Boot.img first before flashing the rom. I forgot and it took me a while to figure out why my apps wouldn't run. Hope this helps.
well i took the plunge ,everything went perfectly ,now i have unlocked bootloader and cwm and a rom cheers

[Q] Please Help

to the great minds of our community. I have a one x and have managed to have it stuck in bootloader loop everytime displaying "This build is for development purposes only. Do not distribute outside of HTC......" I think I have made a series of mistakes most likely due to me rushing into this and not quite comprehending the process. I used to flash my phone all the time during the Windows Classic however have never attempted an android until now. Alots changed
From what I can see I have made the mistake of not creating a recovery image of my stock rom and not installing clockmod.
can anyone help in getting me out of this please. I have attempted to read the recovery guides however maybe im not doing something or not understanding the new lingo but I am unable to restore my phones functionality.
Again any help on this would be greatly appreciated and apologies in advance for a noob mistake. any and all suggestions welcome
haha you can see how long its been since ive been on here just by my signature
Does your bootloader say EVITA?
If it does, this is the wrong forum, installing software from here is a bad idea.
Try the AT&T/One XL forum.

[Q] Help out a new guy?

Hi.
I am very new to the world of rooting and all that stuff, in fact, I have never even attempted to root any of my phones. I currently own HTC One X (International version) which is running the newest Sense 5 Android 4.2.2. update. I tried to follow some youtube videos on how to root my One X but they are all a year old at least and are demonstrated on the stock version of Sense that was on my One X when I got it.. Now I know I am a huge noob at this but I would just like to ask if somebody can guide me trough or at least give me a link to some kind of guide/tutorial which will work on the newest update for my One X. I am very cautious because I don't want to harm my phone by doing something stupid or wrong. Anyways, hope somebody can spare a minute and help me out. And also thanks for taking the time to read my post!

So this works for Sense 5 update? Does it even matter which version I am running on my phone for rooting?

Things are starting to get a little bit more clear now. I managed to unlock the bootloader so far. Before I go any further, is there anything I should look out for, what could go wrong? I've read that if I mess something up I could brick my phone, how can I avoid that? Also, thanks a lot for helping me out!

after you unlocked the bootloader flash custom recovery. then do a nandroid backup. then flash supersu/superuser then do nandroid backup again. you now have 2 backups of stock rom and stock rom(rooted) and when you flash custom rom make a backup again. eat will eat up space in storage but its better be safe.

Question Concerning LG G4

Hey guy, sorry if this is going to be a bit of a noob question but please try and bear with me. In lieu of the recent nexus 5x which i found to be a huge disappointment I decided to pick myself up an lg g4. I'm not the biggest fan of the stock lg Rom and immediately looked for Cyanaogenmod.
I know that no stable build has yet been release for this phone yet and that i just need to have some patience, but I have some questions regardless. I'm wondering if there is a difference between root and an install of cyanogenmod. By this i mean that there are certain installer which will complete the process for you without you having to do any rooting yourself. If i understand correctly the phone is still being rooted but just by a program. My question is, is it only this latter feature that is not yet available for my phone. Like, if I were to root it myself would I then be able to install a cyanogenmod ROM. Or is it that there is not yet any compatible ROM for my device. If it is of any help I have the LG-H812 version of the phone.
Also, I recently saw a video on the XDA developers YouTube channel where it was discussed how TWRP is now available for the G4. what exactly does this mean and is it something that I would want.
Thank you very much for putting up with me.
Sounds like you need to do a bit more research before you do anything. I don't think TWRP is available for your model at the moment, which rules out custom roms/cyanogenmod. You just have to be patient and hope TWRP becomes available, then wait for a stable rom to come along. Or trade/sell your H812 for the international H815 (careful there are a few variants of the H815).

He's right man you Really should start hammering google especially with a more technically involved root with our g4s. No matter what anyone tells you TWRP or another custom recovery is the number one absolute most important thing to do with any root and immediately after you root before you make any modifications beyond normal app installs whatsoever. Custom recovery is what is going to save your ass in a bootloop or brick situation where you cannot get to the OS or even get a response from the device. As long as you have a backup in storage, you can use hardware key combos to enter TWRP and wipe the system and the problem and reflash the backup. Recovery is completely separate from the Rom that's how you can get around a total Rom disaster when nothing else works. The main reason there's no Roms for them yet is cuz only that one variant's bootloader can be unlocked which is required in most devices to flash a Rom or recovery and the reason that even with my capabilities I won't even bother rooting my expensive ass main important phone I'm still paying for every month lol I just fulfill my flash addiction on an l70 on a daily basis and daily I get outta bootloop and bricks thanks to TWRP... The g3 is perfect for playing with and I'm considering buying a used one and o I recommend the same until the g4 is fully cracked......also CM only comes pretty rooted because it does the same thing as normal just by flashing supersu which is a breeze with TWRP also
Through my ancient eyes comes the certainty of decay... LG G4 & L 70

Newcomer Questions

Hello, so I'm going to be receiving my HTC One M9 tommorrow morning, and I was hoping the XDA community could help me with some fundemental questions regarding my new phone.
So, first off, this is a Verizon version, but I'm 95% certain that it comes factory unlocked. HTC6535LVWSG. I hear some people have issues rooting/S-OFFing the Verizon version (VZW at least, but I don't think mine is), but if it's not that version (or already unlocked, for that matter), does that mean that I will be able to load up any recovery from here? Assuming that I've gotten a recovery installed (my past phone was an EVO 3D, which I've tinkered quite a bit with), will I be able to use ROMs posted here? Or will I need to use specially made Verizon ROMs?
All of that aside, do you know where I can find the Marshmellow RUU that I heard just came out for the M9? As mentioned in the earlier paragraph, will I need a special GSM version for it?
EDIT: I found the news post at HTC, I'm assuming that it would work for any M9.
Thanks for anyone who responds!

NO! SLOW DOWN!
If you get a Verizon M9 do not flash anything!! Unless its specifically for the Verizon M9 or the developer of the ROM/Kernel states it will work with CDMA or Verizon M9's.
As of right now only the GSM Marshmallow update is out. Do not flash this RUU/update on a Verizon M9. It's better if you start off by just looking around for Verizon M9 threads. Ask questions in other threads if that particular ROM or file will work on a Verizon M9 or better yet read through most if not all the posts in those threads because more often than not someone in your shoes has already asked the same question.
But if you received a locked/S-ON device do not update/change anything on that phone until you've freshen up on whether or not S-OFF/Rooting is available for the software that comes already on it. It'll save you the headache of playing around with a new phone and it auto updates now your stuck without S-OFF.
Also don't ask questions in "General" that's what the Q&A section is for.
Congratulations! I think you'll be pleased with the M9.
Diaclaimer: I'm a hobbyist and not an expert - you should do some reading of threads and
research before attempting to hack your phone.
A few things:
- you may find better help in the Verizon HTC M9 forums (http://forum.xda-developers.com/verizon-one-m9)
- S-OFF is currently only possible on Verizon's variant of the M9 via a Java Clip. They're expensive, but there are fellow XDA members who own them and are willing to use theirs on your phone, usually for a reasonable fee
- until your bootloader is unlocked (pretty sure that your phone will NOT come that way - Verizon is not user-friendly) or you are S-OFF, you will not be able to flash a custom anything (recovery or ROM). Attempting to do so may render your phone unusable.
- Marshmallow has been released officially for the developer/unlocked variant of the M9, which is GSM-only. The Verizon variant is CDMA; the RUU will fail to install on your device.
Hope this is helpful. You probably have a bit more effort to go through to be able to hack your phone, but it's very doable and worth the effort. The M9 is a solid device and all the moreso once you have S-OFF (or an unlocked bootloader) and root.
Unfortunately, UPS Next Day Air has failed me, with yet another delay, so I won't have the phone today. :v
I know it's already paid off, and I'm pretty sure it's factory unlocked. What determines if it's a VWZ version or not? How does this affect my modding processes? I hear of several people who can do stuff to "non-VWZ" versions.

Not for the vzw m9. Big difference is the versions they can do already can use htc dev to bootloader unlock and root. Vzw is another can of worms because we need a root exploit before anything can happen.

So, I got the phone today. It was supposed to be delayed but I guess they managed to deliver it! I have to go, so the phone is gonna sit here for a couple hours, but it can boot into the bootloader (I'm not sure if this is a sign that it can be unlocked, but we'll see, I guess.)

Any phone can boot into the bootloader. To determine your phone's status, you'll need to look at the upper left corner when you are in bootloader mode: does it say 'unlocked' or 'locked'? Similarly, does it say 'S-ON' or 'S-OFF'?
First of all you should, in my opinion, deal with the differences of a CDSM to a GSM device in detail and read especially the Verizon specific threads in this forum very carefull.
Seconed to it you should pick up the full information about block based OTA politics, and the major changes regarding moddifications to Android 5.1.1. If never done before you should also read the basic threads abaut unlocking, rooting, fastboot as well as adb commands. If need for further help occurs it is hightly important to be able to explain when, where and assumingly why a problem/error occured.
Besides this have fun with your One M9!

Ah, I know the ins and outs of adb and fastboot already, as I've had my fair share of working with the HTC bootloader-- however I just wanted to clarify some things that I had not previously known. Thanks for the advise, though.
Guys please, anyone can verify that the buttons (power and volume) are a bit 'down after a few months of use??
