Hello all, haven't been on this forum for awhile, Ha!
Anyways, my m8 wasn't receiving calls a couple years ago so I of course thought it was my ROM. I flashed several, and most calls didn't come through. I could make calls, just almost all didn't go through (very few did)
So, took it into the att store and the guy said the antenna was probably corroded. I don't think that's the case, as data worked fine and texting did as well. Just recently, it hit me to try and update the modem. I've searched and searched but couldn't find out how. Here's some info:
HBOOT: 3.19.0.0000
RADIO: [email protected]
Unlocked - S-ON
TWRP v3.2.1-0
Any help on updating modem would be great. I'm looking to get rid of my s7 edge (Locked bootloader can kiss it)
*Id like to do this without relocking my bootloader
"Corroded antenna" sounds like hogwash, and the store employee just making up crap, so he didn't have do anything (or didn't know what he was talking about).
Since you mention the AT&T store, I will assume you are using the AT&T network. Is so, I think (pretty sure) you have the problem described in the following thread, and the solution should work for you: https://forum.xda-developers.com/htc-one-m8/help/receive-calls-make-detailed-thread-t3146670
You may need an AT&T Tier 2 tech support to turn off HD Voice. Tier 1 tech support may not know what you are talking about - or may claim incorrectly that it can be done (this has been reported by others).

It does appear from your radio number, that it is on the older side (Lollipop). Therefore, it may not be a bad idea to update to Marshmallow firmware (the latest you will be able to get, since HTC doesn't support the device any longer).
You aren't going to see any major differences from updating the firmware (as mentioned, it's probably not the cause of your voice call problem). In fact, I was running MM custom ROMs on the M8 for a long time, with LP firmware; with no negative results observed. But it's typically recommended to have the most updated firmware for maximum compatibility with the current ROMs.
Unfortunately, you can't do this with an unlocked bootloader (since you are s-on). You unfortunately cannot flash firmware with an unlocked bootloader, on this device. For that matter (what you are asking originally) you can't flash the radio separately with s-on, at all. But you can flash the signed firmware (which includes radio) with a relocked bootloader.
You can flash the AT&T Marshmallow firmware using the following guide: https://forum.xda-developers.com/showpost.php?p=67123738&postcount=7
No need to do the part "Install RUU" if you want to continue using a custom ROM (with HD Voice disabled on your ATT account). So the process would be something like:
1) Backup any data you want to keep, by method of your choice
2) Relock bootloader with command: fastboot oem lock
3) Flash firmware using guide linked above
4) Unlock bootloader again, using the old unlock bin code, or get a new one from HTCDev.com
5) Install TWRP again (flashing firmware replaces TWRP with stock recovery)
6) Flash the custom ROM of your choice again

I just bought a new at&t HTC One (M8) and I'd like to have a fresh stock backup in case of return/warranty problems. I'd like to make this myself so I can ensure that I'll be able to put the exact software that came with my phone back if need be. Also I'd just like to know how to do this in general. What I've found via search has been for rooted phones or different brands. Is it possible to use ADB or any other tool to do this? I guess I'm confused because I see posts for flashing back to stock. How do devs get these stock roms? If someone could point me to a good guide/tutorial it would be much appreciated.
Not without a rooted device or an unsecure [email protected] backup...there is an ruu posted for the 1.58.502.1, thats as close to being a backup without altering the phone in anyway
As long as you are a current account holder, AT&T does not give a crap what software is on your phone, bootloader unlocked, even a custom ROM installed in regards to warranty service based on many reports on XDA.
If you are still wondering about returning to stock, as mentioned in the above, your version (AT&T) if fortunate enough to have a 1.58 RUU. The ROM Update Utility is a useful means of installing a full stock image (ROM, radio, recovery, etc.) via connection to a PC.
But it can still be determined the bootloader is unlocked, no matter what you do to the phone to return it to stock. Your IMEI is tracked by HTCDev.com when you unlock the bootloader. But again, as long as you go through AT&T for warranty service (highly recommended for this reason) they don't care if the phone is modded.
I believe the stock ROMs you mention are system dumps done after bootloader unlock.
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.
I just bought an AT&T HTC One M8 that came with android 4.4.2 KitKat. It apparently doesn't have any available android lollipop updates since checking for updates using the "AT&T Software Update" option in settings returns a "no updates available" which was weird, but I didn't mind since I was planning to root this and flash a custom rom.
I read up on guides on rooting and unlocking the bootloader which was pretty standard for most android devices. However, S-on/S-off and hboot are 2 things that are confusing me a bit right now despite doing quite a lot of searching on XDA. To my understanding, S-on/S-off is some kind of HTC protection that needs to be disabled to flash certain roms, and hboot seems to be what people are calling the HTC Bootloader (someone correct me if I'm wrong). If I'm correct, I seem to have hboot version 3.16 according to CPU-Z (I checked the Bootloader version number).
After enough reading, it seems like having the latest hboot version is relatively important for flashing many roms (3.18-3.19 I believe), but I have found no guides on how to do this. My only lead so far is the following thread with 1 reply: http://forum.xda-developers.com/att-htc-one-m8/help/update-hboot-3-18-3-19-t3236897
"Backup any personal data you want to keep (off phone, it will be wiped). Relock the bootloader, run the latest AT&T RUU."
So ok, I guess it's a good thing I'm doing this before rooting the device. However, What's the AT&T RUU? My closest guess was using the HTC Sync Manager on windows to find firmware updates manually, but upon trying this (installing htc sync manager and connecting my HTC One M8) and on the menu clickling "Check for updates", I just get an error message saying "Unable to connect to the live update service".
Then, after some more searching I found this thread: http://forum.xda-developers.com/att-htc-one-m8/help/how-update-bootloader-to-3-18-0-0000-t3006738 which said the following:
"Follow instruction on the following thread for updating firmware, and select the 3.28.1540 firmware file: http://forum.xda-developers.com/att-htc-one-m8/development/att-4-4-3-2-22-1540-3-debloated-sense-6-n"
So, here I am. Unsure whether to follow this instructions since I have no idea what that firmware is or if it will brick my device, or whether it will work since I still haven't rooted or unlocked my device's bootloader and I don't have S-Off (and that thread clearly states S-Off is mandatory for flashing to work). Any ideas?
---------------------------------------------------
edit: I just found out what RUU stands for, but I have been unable to find this "Rom Update Utility". It's spoken as Windows software, but I can't find where to download it. Any help would be very appreciated

S-off is not needed to flash any ROMs. S-off is one way to update the firmware needed to run a ROM (more on what "firmware" is in a bit), but s-off isn't strictly need to update firmware either (other ways to do it s-on).
s-off is needed to modify (hack) certain partitions that are protected even with the bootloader unlocked. Such as hboot, radio, and some others. But its only needed for those specific things; and not needed to flash custom recovery or ROMs. And note that you can still update hboot, radio, and other firmware by "official" means even with s-on.

Yes, hboot and bootloader are the same thing, as far as HTC devices are concerned.
Not only is the latest hboot needed to flash the current ROMs, but its important to update the entire firmware package. Firmware includes not only hboot, but also a number of other critical modules such as radio, WiFi, Bluetooth, and others; that all need to be updated in order for the current ROMs to function properly.
Good news, you are on the right track, and the proper RUU will update not only hboot, but all the firmware.

I've created an AT&T index thread to catalog such things (sticky to the top of the General AT&T M8 section). It explains what an RUU is, and has links to all AT&T RUUs. You will want the latest RUU (4.28.502.1 or 4.28.502.2 - they are mainly the same except the latter has the Stagefright fix):
http://forum.xda-developers.com/showthread.php?t=2751432
The RUU is rather self-explanatory. As mentioned previously in this thread (and on the Index) your phone will be wiped by the RUU. So backup anything you want to keep by your method of choice. Then simply download the RUU to a PC, connect the phone. Then run the RUU program, and it will walk you through the process (you basically just need to confirm a couple dialogue boxes, and the RUU will do the rest and automatically update all the software/firmware).
After that, what you want to do in short is:
1) Unlock the bootloader using HTCDev.com
2) Install TWRP 2.8.7
3) Flash your custom ROM of choice
4) Beer
just wanted to say i had been running my verizon note 3 (non-dev edition) like everyone else here
with the bl unlocked to dev edition and rooted most likely with either kingo or supersu through teamyemin or proyemin and i think there is another one too.
basically if you want to go back 100% original (including your original cid) its not as easy as you might think.
first thing i did was wipe everything that was possible to wipe from within twrp recovery.
next i booted to odin download mode
from there i flashed the OB6 official firmware
then i rooted using the kingo method as this seemed the most likely not to infect my computer and possibly only stole info from my phone. (this used the 2 files 1.tar and 2.tar flashed with odin for pc)
i then verified my root and installed terminal emulator end es file explorer root
i copied samsung_cid to phone sd card and used es file explorer root to move to ./data/local/tmp
changed my cid back to original and rebooted phone
booted to stock recovery and wiped everything i could and booted into odin download mode
flashed OF1 official
there is a very important part that could get alot of ppl phones into brick mode.
when you goto change the cid back to original you better already have the stock BL on and running and >>>NOT<<< the DEV-BL
that is why i chose to flash an official OB6 rom first
if you try to change the cid to original non-dev edition and reboot your phone this could have problems since you would have the dev bl flashed with a non dev bl cid
when the cid for the dev edition became available you could change the cid first and boot into the bl and it would say something like developer mode enabled or someting like that even if you had the stock bl flashed (not the dev bl)
this is fine
only problem is if you change that cid back to stock/original non-dev while you are running the dev bl
i dont know what would happen but i bet it wouldnt be good.
ok next part i think is important is getting rid of kingo root as much as possible and that is why i flashed the OB6 firmware first and then OF1 for my very last step.
ok thanks.
i know alot of ppl are probably gonna say why would you want to go back to stock original cid and my answer is this.
phone is really stable and also if i want to sell it which im thinking about.
hope it helped some ppl.
Where do we get our original Cid?
The method used to do the unlocking runs the tool in two passes, like this:
pass1: change the CID.
pass2: (create debrick image &) alter the aboot partition sig to the DevEd sig.
There is no reason this can not be reversed (assuming you have root on ANY ROM) e.g. :
pass_negative_2: flash stock aboot to aboot partition.**
pass_negative_1: revert the CID by altering the original code to write your CID (minor code change and recompile).
** must be from the exact same version of boot firmware you have on the phone; you could use "dd" for this.
There's no reports of people trying this explicitly, but OTOH note this: there were owners of DevEd devices that accidentally flashed stock bootloaders. They didn't change their CID, and they didn't brick. They just couldn't go back to an unlocked bootloader any longer, or boot custom kernels: they converted their phones to retail without ever changing their CID.
Anyhow, it appears that you went through a ton of effort, when all you needed to do was flash the stock "aboot" back into place.
It probably isn't even necessary to revert the CID back.

You recorded it - as a precaution - when you went through the unlocking process. Didn't you?
As I mentioned above, it probably doesn't matter anyway.
@OP: did your "Custom" boot logo disappear eventually?
PS even after doing this the phone will still have a blown knox warranty flag and certain TZ/qseecom functionality will no longer work, even with 100% pure stock on the phone.

Does by record do you mean by using a tool or like taking a picture of the cid

Cut-n-paste to a text file.
The tool spews out onto the screen the device's CID before it goes about changing it.
That assumes you followed the directions in the OP and used ADB. Or, didn't follow those instructions and used a terminal emulator. (I don't know whether or not the app shows you the output from the binary).
As I mentioned, folks that had DevEd devices (that is, "factory unlocked" bootloaders) that made the mistake of flashing stock firmware turned their DevEd phones into retail phones - without ever changing the CID to some other value. So it may not even matter - you end up with a "retail" phone with the same CID that you currently have.
In any event, if you didn't record the previous CID, there's nothing to do about it.
The OP mentions something called "samsung_cid". I presume he is talking about a mod of the original code that allows you to re-write the CID to an arbitrary value.
There is a master list of stock recovery versions for the HTC One. How do I determine which version I should be using?
None of those. That is hardly a "master" list. It's over 3 years old, never updated past the original Kitkat (M8 release) recoveries, and woefully obsolete. You'll want your recovery number to match your OS number (main version on bootloader screen or getvar all). Also, none of those are valid for AT&T version M8 (which is what I assume you have, since this section is specifically for the AT&T M8). It would need to have "502" in the version number x.xx.502.x which specifically denotes AT&T.
Why exactly do you want stock recovery? Most folks want this, in order to get OTA updates. But you will also need a stock, never rooted ROM (unrooting doesn't work), and also must be connected to the AT&T network. It's probably easier to relock the bootloader, and update by RUU. Note that RUU will wipe all data from the phone. See RUU section in my Index thread: https://forum.xda-developers.com/showthread.php?t=2751432
If you really want stock recovery, you should be able to extract it from the firmware.zip. Find the right firmware version number from the firmware collection, and extract recovery.img from the "Stock, Full Wipe" firmware zip:

That is definitely helpful. Thank you. I didn't realize that I could pull the bootloader out of the firmware.zip. The phone was AT&T and later unlocked and made in to a rooted Cyanogenmod phone. I had to un-root and install Android GPE. It's not really AT&T anymore. Now I can download OTA updates, but cannot install them because TWRP is still the bootloader. I would rather do the OTA updates since the phone is already stock-ish and resetting everything is only slightly preferable to stabbing my eye out.
Since I'm unlocked on marshmallow, it looks like I want the 6.12.1540.4 zip.

Recovery and bootloader are two completely different things! You can pull recovery.img from firmware.zip, and flash with fastboot. I would not do this with bootloader, which would require s-off (to flash manually) and it would still be risky. Better to flash the whole firmware.zip or RUU, if you want to update bootloader. But I don't think that is what you meant.

Your description is confusing, and I think you're mixing the terms up again. 6.12.1540.4 is the version number for the US Developer's Edition, which is Sense, and not the same as Google Play Edition (GPE) which is not Sense.
To OTA, the version number of the current stock ROM needs to match your firmware number (in bootloader and getar all), and you also need matching stock recovery.
To be clear, what is the current ROM (and version number) as shown in Settings? And also do fastboot getvar all, and post the result (delete IMEI and serial number). Need those pieces of info, before I can properly advise what stock recovery to use.
