[Q] (Australia) HTC one M8 ROM/flashing. Please help me out thank you

Hey guys im new to xda and also ROMs in general so any help at all would be much appreciated!
Im trying to flash a ROM so i can use my HTC one M8, im currently stuck on bootloader/recovery.
I have tried to flash 6 different ROM.zip files with no success, i get all prompts as though the file flashed successfully but when i reboot system im still stuck on bootloader.
what i have been doing is
1. move .zip file to SD card
2. open TWRP wipe dalvik/cache
3.install .zip from SD using TWRP
Is there something missing or is it the ROMs i used?
i dunno if this is right but I was told i need a ROM that is specific to Australia, i havent found one

i have followed your steps and after flashing recovery img, then reboot. i get a red triangle in front of a phone screen.
if you could please stay with me until i fix this i promise to donate to you. you have my word. its either that or pay whatever they tell me to

Do you really follow all steps from 1 to 11 (step 11 is when you need to flash stock recovery image)
1. You need to use TWRP 2.8.1.0 as recommended.
2. When you do restore, do you see the progress till it said success ?
From your above post, it seems the restore was not successful or not correctly done.
You can try again .. reflash/install TWRP 2.8.1.0 and follow the steps again.
Note : I don't do this for donations ... so don't worry about that.

Great :good::good:
You're going to have multiples OTA (at least 3 OTAs) as your current base is too old. After one OTA done, check again for another one until it says no more updates.
After the last OTA which is Lollipop, to install a Sense based custom ROM, you need to flash/install TWRP 2.8.5.0 or 2.8.6.0 (recommended). Don't use any lower than 2.8.4.0
It's not needed .. thanks for the donation .. highly appreciated.

One M8 won't OTA update on stock

I restored my M8 International Unlocked Dual SIM Version to stock through a nandroid backup and then flashed one of the recoveries I found online but my phone won't update through OTA. I then tried restoring different backups. Some of which worked and some didn't even boot.
I finally came to the conclusion that it was because of the HBOOT version and maybe the version-main.
I want to know:
1- Understand version-main.
2- How can I know which nandroid backup is right for me. (and if possible point me to the right ones for me).
I searched quite some time but couldn't turn up with a complete answer. Forgive me if I missed something.

I don't own the dual SIM, and can't speak that specifically on it. But what I can say:
1) Main version is the firmware number. It won't change when you restore a nandroid.
2) You will want a nandroid that matches your firmware number. If you are trying to flash backups for the "regular" (single SIM) M8, these will never work on your phone. Dual SIM nandroids are probably pretty limited.

What's the error ?
Is it stuck on red triangle ? If yes, press & hold volume up button and press power button once. This will get you to recovery and read what error that you have there.

Thank you Redpoint,
I bricked my phone before, and was able to fix it using the backups and recovery from the below link and everything was fine, I was able to install two OTAs and get lollipop.
http://forum.xda-developers.com/htc-one-m8/help/rooted-m8-dual-sim-bricked-s-t2979774
But now, when I restore that backup and original recovery, then install any OTA update, the screen becomes black. I know the phone is working fine as I can hear the sound when pressing the volume key or when someone calls. But no screen! The link above is to a thread made by me and the only difference i can see between that time and now is the HBOOT version and the radio/baseband. This is driving me crazy!

This is sounding really rude. How about asking nicely?
Nobody here is getting paid for their time, or sitting at their computer 24 hours a day to help you. You need some patience.
Plus, the dual SIM version is not terribly common/popular, so getting the specific help and files needed may be a challenge. Folks here are helping as much as they can, when they can.
Its hard enough, that you can't figure it out, right?

What backup and what OTAs specifically? The statement is to vague for me to see what you did.
List the version of the backup (link to a link to a link doesn't help me) and what version OTAs did you try.
Where did you get the OTA files from (specific post, if applicable)?

This means your firmware is different for before. This is not a minor thing, its a huge difference.

That's because you restored a very low version of backup when you have a high version firmware installed.
What I understand here, you restored 1.45.401.12 but your firmware is 4.30.401.15
When you restore a backup (when your device is S-On), the lowest version that may work on your device is 3.33.401.6 but not 1.45.401.12.
And the correct version to restore is 4.30.401.15
If you don't have this 4.30.401.15 backup and unable to find it for now, just to have a good running device, you can install custom ROM made for your device.
I believe this is a good one : http://llabtoofer.com/2015/05/08/htc-one-m8-dual-sim-maximushd-3-0-0/
(note : you should have made your own backup when you first fixed your previous problem)

I assure you that I AM grateful for your help otherwise I wouldn't thank you for your first post which suggested to restore a nandroid backup for a dual SIM which I already did.
Anyway, please accept my apologies for this misunderstanding.

I restored the same backup that I used to fix my phone the first time. It is currently deleted but it said it was version 1.45.401.12. Which worked flawlessly and I was able to install OTA updates.
The update I'm trying to install currently is version: 3.33.401.6. for Android 4.4.4. It is an over the air update by the phone it self.

No worries, your apology is accepted. And I gave you your first "Thanks" too!
I look at most all new posts in this section, and respond if I have something to contribute when I have the time (and ckpv5 looks to operate very much the same way). So the lack or response was due to me not being online, and otherwise unable to spend the time on XDA (and nagging won't change that). Therefore, "bumping" a thread to the top is usually not necessary. Or if you choose to do so, try to pose it as a polite appeal for help (in the form of a question, and using the word "please" can work wonders).
The way you posted it, sounded more like you were making a demand or giving orders.

Did you install the 2.xx.401 OTA before trying 3.33.401? Because this is mandatory (OTAs need to be installed in sequence, and you can't skip any).

Your main version, hboot, and radio numbers given in your top post all indicate you are on the current Lollipop firmware.
The issue is getting a ROM on the phone that matches the firmware, as ckpv5 has given you suggestions on how to do (4.30.401 nandroid is what you want, if you can find it).
You may be confusing "firmware" with "ROM", as they are not the same thing.

He can use one version lower 3.33.401.6 too.
And he can find that 3.33.401.6 backup in the link that I posted above.

Why relock bootloader ? It's not needed. Unlock it again as you need to flash correct recovery.
Boot back to fastboot usually happen when you flash wrong recovery especially a recovery meant for other device.
From where you get the recovery ? You only mentioned somewhere on the net.
Use 3.33.401.6 recovery or 4.30.401.15 recovery. Either one should work. You can get them in link in my signature.

I flashed the stock recovery so I locked the bootloader to install the OTA. Don't you need a locked boot loader to install an OTA?
Man, don't make me feel stupid more than I do now. I'll get a Nokia and then kill myself. [emoji30] [emoji379]
I'll try one of your recoveries as soon as I'm home.

No .. no need a relocked bootloader for OTA. (doesn't matter your device is S-On or S-Off)
Relocked bootloader only needed when your device is S-On and you want to :
1. Install a HTC RUU
2. Install a HTC signed firmware

Ok, so I flashed that stock rom you mentioned earlier and and one of your stock recoveries and Voila! Everything is perfect, except WiFi. When I turn on WiFi, it says "Turning on.." and stays like this indefinitely. Any idea?

Well, I have tried everything to fix the WiFi problem to no avail. Finally I got fed up and decided to use the room you provided. Thanks ckpv for your help. I appreciate it.

I don't have your device version so I can't confirm anything why the wifi won't work on your device.

Running android 4.4.3 with root; how to upgrade to latest Marshmallow and retain root

As per the headline, I've got an HTC M8 that I rooted shortly after purchasing in 2014. When the Lollipop OTA upgrades came out, I was reading mixed reviews about battery life and system performance, so I used a quarantine app to freeze the auto-update app so that it would stop bothering me to upgrade all the time. Now that Marshmallow has been out for a few months, the reviews seem positive and say that battery life is improved and the device is just as responsive as it used to be, so now I want to upgrade my device to Marshmallow.
I'm more or less an android / phone newbie - I mainly just use my phone for email, web browsing, driving directions, taking photos and the occasional app like banking, I'm not into heavy customisation but would like to retain root for the ability to uninstall shovel-ware, freeze programs and so some minor customizations.
Anyway, since I have 4.4.3 Android rooted, which process should I follow to get Marshmallow rooted, while retaining all the current data on my phone (apps, phone contacts, etc)? Do I need to do an OTA upgrade to Lollipop, and from there do an upgrade to Marshmallow?
My phone is an unlocked HTC M8; it's not a GPE or other branded vendor phone. I live in New Zealand and I bought it parallel imported, I think it was originally from Hong Kong.
I already have some of the bootloader/recovery stuff sorted out from when I rooted it the first time. Going into bootloader this is what prints out for me:

Please upgrade your firmware first through RUU to flash other ROMs.
[Edited]

Would this be the same as stock OTA?
Also wouldn't flashing a ROM destroy all my apps and data?

No the ROM won't be same as stock OTA,there are more or less modification in every ROM.The way you can exactly stock update by flashing RUU.
And yes all your apps and data will be wiped.Why don't you try titanium backup?you can backup all apps and app data with it.

Upgrade TWRP to the latest version.
Flash any MM ROM with S-On support.Though most of the ROMs doesn't require S-On,but but read and read about the ROM before you flash it.
Edit:You can try ViperOne ROM for the first time,i find it more stable.

MM ROMs won't work properly with his old firmware. He will lose wifi, among other issues he will face. Updating his firmware is a MUST before he flashes a Marshmallow ROM

Sorry for the wrong infos.
I flashed other mm ROMs over lollipop firmware everything's working fine.
But just got to know about firmware upgrade myself an hour ago.
Sorry again.

First off, you need to update your recovery. Go with TWRP 2.8.7.0 or higher.
Secondly, you can update and keep all of your data. Make a nandroid backup with your new recovery, then run the appropriate RUU to update, or go back to complete stock and take the OTAs that will get downloaded to your phone, then restore your nandroid. The new firmware won't get overwritten by restoring your backup. That partition isn't included in the backups.
Hook up your phone to your PC, get into fastboot, and enter the command fastboot getvar all. Post the results here (minus your IMEI & serial# ~ that's private info) and I or someone else here will direct you on the easiest way for you to update.

Yeah, MM ROMs will work with Lollipop firmware, but not with KitKat like the OP has.

This implies that if I unfroze the OTA updater on my current software and let it simply upgrade, that it wouldn't work properly? So either way I have to "run the appropriate RUU", OR re-flash a stock 4.4.3 image and then do OTA upgrades on that?

No, a nandroid is a backup that is made by recovery (TWRP). It can back up the stock ROM, and user data (which is the goal in the above posted suggestion). After you update, you can restore the user data (but you don't want to restore the old ROM, since the goal is to get to MM - that part wasn't clear in the previous post).

RUU = ROM Update Utility
Its an official HTC tool that completely updates or restores the stock image.

Since you rooted, you can't simply unfreeze the updater and OTA.
OTA requires restoring the stock ROM (never rooted, unrooting does not work) and stock recovery (you have TWRP now, which is a custom recovery). RUU is an easy way to restore the whole phone to stock condition.

Ok, so if I'm understanding this correctly:
* To use the OTA updates, I need to have a stock ROM, as well as a stock recovery (not TWRP)
* I can make a nandroid backup of user data in TWRP, and then use RUU to go back to a completely stock phone
* From there I can do OTA upgrades to get up to MM
* Then I can install the TWRP recovery and restore my user data
Another approach might be:
* Backup the user data using TWRP
* Use an appropriate RUU, or series of RUU's, to upgrade to MM, without using any OTA updates at all
* Restore user data
It seems like path 2 would be easier and less risky of making a mistake. So what RUU's do I need? The output of "getvar all" is available a few posts up.
Also is there an easy guide somewhere for how to upgrade to a newer version of TWRP?

Yes, path 2 (RUU) would be easier in your case. But unfortunately, I don't think you version has RUU. You'd be looking for an RUU for 6.12.709.4
That being the case, you need to resort to path 1 (return to stock and OTA updates).

Fastboot install method is simple and reliable. Instructions and TWRP files here: https://twrp.me/devices/htconem8gsm.html
Since you already have fastboot working, just put the TWRP .img file in the same folder as wherever fastboot.exe is located, then connect the phone, and run the command:
fastboot flash recovery twrp.img

Right, I've just sat down to try and do this, and realised that I'm still not clear on what I actually need to do.
It seems there is no RUU for my phone for MM, which would be RUU for 6.12.709.4.
So instead I need any RUU that suits my phone for Kitkat or Lollipop, and then do OTA upgrades from there? So what RUU versions should I be looking for, since 6.12.709.4 does not exist?

There is no RUU for your device version. You can only restore to stock ROM and do OTAs up to the latest.
Your main mistake (I remember you have the same problem before) is restore your backup data after OTA done. Restoring old data that removed your apps like calculator & flashlight.
What you need to do (correctly):
1. Don't use that TWRP 2.7.0.2 .. install 2.8.10 or 2.8.3.0
2. Make a TWRP backup of your current data/system/boot
3. Restore non-rooted backup 2.22.709.3 (boot and system only - use your current data)
4. Install 2.22.709.3 stock recovery
5. Do multiple OTAs up to the latest 6.20.709.2
You'll upgrade your ROM and firmware but still have all your data intact.
All files needed are here : http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
If you happen to wipe all data & system before restore 2.22.709.3 (as per step 3), you can restore data only from your own backup before step 4 ... remember to restore your own data before OTA, not after OTA (if not you'll have your old problem again)

RUU Link - Removed | Wrong file, was not an RUU
Though I'm not sure whether it is official or not (signed or not) as the name of the file is really small.

That's not RUU ... it's a ROM flashable zip. Maybe you better remove the link so it won't confused others.

Right, I've finally gotten around to doing this, and the process was pretty straighforward. Thanks very much for your excellent help ckpv5.
So I'm now on 6.20.709.2, but I don't have root. How can I root this phone?

Need to update my Rooted M8 from lollipop to OTA marshmallow.

Hi folks, So finally i am ready to update my Supersu rooted,S-OFF, Rogers M8 to the marshmallow OTA update which has been showing as a notification from the last couple of months.I asked same question last year but at that time there was no easy way to update the rooted phone other than finding stock backup.
Any new way came to update without finding stock backup?I would really appreciate if someone can give step by step.Thanks.

hi
you can just flash the RUU which will update your device to official marshmallow ( and it will wipe your internal storage so make sure to backup all your data )
here is the RUU

The file says "signed". If that is true, there is virtually no way (at least form a practical/feasible sense) for it to be anything but an official HTC RUU. My understanding, the encryption involved with being a signed file is far too complicated for anyone to bother messing with (never heard of anyone breaking that encryption to make a file "signed"). At least, its not worth it to spend all the time to make it "signed" just for the purpose of malware, etc. Far too many other "lower hanging fruit" possibilities.
That being said, since are s-off, I don't know how you would verify that file is truly signed. With s-off, you can flash unsigned RUU files. With s-on, only signed RUUs will flash. But I don't know its worthwhile to go s-on just for the purpose of making sure the RUU is signed.
You've already flashed custom recovery and a SuperSU file, all from 3rd parties (maybe from reputable sources, or not). There is no more or less reason to believe those files are safe.

Its because i did rooting and S-off by myself (i am not an expert in any way.Did it by reading and getting help from XDA)on my brand new phone using third-party software (But well known and reputable sources-SuperSu and Sunshine).

You can use your TWRP backup 2.23.631.2 that you already have and you need to install 2.23.631.2 stock recovery to accept and install OTA but this is not productive. See option 2 below for the reason.
You have 3 options :
Option 1 :
You can install the RUU zip as mentioned in post #2 - http://forum.xda-developers.com/showpost.php?p=70110165&postcount=2
It is a HTC Signed RUU and that's the reason why you need to use htc_fastboot to install the RUU not the generic fastboot
Personally, I don't like to use RUU as it is a hassle to backup all my files from Internal Storage as this RUU will wipe everything on the phone.
Option 2 :
As you have a S-Off device, you can use your TWRP backup 2.23.631.2 that you already have but you need to have stock recovery 2.23.631.2 installed to proceed with OTA.
But this is not productive as you need to accept and install multiple OTAs
2.23.631.2 --> 3.34.631.4 --> 4.20.631.2 --> 4.20.631.3
Also you need to restore all boot, data & system from 2.23.631.2 as your current data on 4.20.631.3 won't work on 2.23.631.2
Option 3 :
As you are running a rooted stock ROM (if not, you won't receive OTA notification) and on 4.20.631.3 firmware, the best for you is restore a stock non-rooted 4.20.631.3 backup.
You only need to restore boot & system, no need to restore data. This way you have all your data intact, no need to re setup after OTA to Marshmallow 6.13.631.7
You can get the non-rooted stock 4.20.631.3 backup and stock recovery 4.20.631.3 from my thread - http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860

HTC One M8 Blocked on reboot after root

I wanted to root my HTC One M8 to uninstall unnecessary applications. I describe the procedure that I survived:
1- I unlock the HTC One M8 bootloader
2- I installed the CWM Recovery: recovery-clockwork-6.0.4.8-m8.img
3- I proceeded to the root with UPDATE-SuperSU-v2.46.zip
And at restart it's where everything gets complicated. It remains stuck on the logo of the boot and can not restart anything. I left for more than an hour to see but nothing moved.
I managed to enter bootloader by associating the volume + and Power key to restart, and when the phone turns off before restarting I do volume- and power.
And the I'm stuck I know more manipulation to make my HTC one M8 work again.
Is the phone ****ing kind unrecoverable?
How to recover my phone?
Help me please

The files (custom recovery and SuperSU) you used are horribly outdated. Unless your current firmware is something like Kitkat, the stuck on boot situation is expected.
Additionally, CWM never officially supported this phone, and that in itself may cause some problems (in addition to being outdated as well).
Correct versions depends on your current firmware number. Most folks (but not all) are on Marshmallow at this point. But you can tell us more by posting what it says for OS number on the bootloader screen. Also, if you know how, do fastboot getvar all, and post the results (delete IMEI and serial number before posting).
But likely, you should use a TWRP version 2.8.7 or later. And SuperSU 2.79 or later. Or Magisk to root (latest is 13.3, which should work).

Yes indeed I had chosen the wrong files (custom recovery and SuperSU). The phone was on Marshmallow. I opted for a simple solution: to install a stock rom Android Jelly Bean 4.4.2 and wait for the update Marshmallow. But before I have installed last version of TWRP. After installing my rom stock, I installed stock recovery and I relock the bootloader.
thank you for your help

I don't think this will work. Your firmware indicated by OS number (in bootloader, not in OS Settings) will still read as updated (MM) and you won't be prompted to update.
Additionally, just as FYI, it is not necessary to relock the bootloader for an OTA update, only for RUU or flashing stock signed firmware.
Stuck on HTC logo screen due to old version TWRP and SuperSU, can often be fixed simply by using the proper updated files. But in the current condition, you will need to unlock the bootloader again. In light of that, it might make sense to restore by RUU (if you version has one - you haven't provided the info requested) or otherwise restore to MM (so ROM matches your firmware) before trying to root again.

Excuse me for my absence. I need your help.
As I said earlier, I opted to go back to a Stock ROM.
Actually as you said, I can not install the update to Marshmallow. It downloads the update but it crashes at installation.
I am sending you the information you requested:

No surprise there. It's best you follow the advice given, instead of making up your own solutions, unless you really know what you are doing. This device has a lot of nuances, and what seems like common sense or a simple solution, often doesn't apply.
OTAs will not install on this device with TWRP, but rather require stock recovery. But it probably doesn't matter, as I stated before, since you are trying to load an update (ROM + firmware), when the firmware is already updated (even if the ROM is not updated), it will likely not install. Basically you have mismatched components, and this will prevent the update from installing. ROM is older, but firmware is updated (version main in getvar indicates firmware is Marshmallow 6.12.401.4).

What version TWRP? You mentioned before the "latest" but did not give a version number. I've had a lot of cases where folks thing they have the "latest" but when prompted for specific version number, it turns out to be an old version.
Just want to be sure before we proceed. After all, the other files you used are going on 3 years old.

I had installed a stock recovery and relocked the bootloader after installing the rom stock. I received an update for Marshmallow but that crashed at the installation.
After I wanted to install a Rom Custom Nougat for HTC M8, so I unlocked the bootloader, installed TWRP (version twrp-3.1.1-0-m8) then root with SuperSU (the SR1-SuperSU-v2 version. 82-SR1-20170608224931). I installed the rom that no more.
So I reinstalled the rom stock Jelly Bean 4.4.2. That's why I have the TWRP installed and the bootloader unlocked.

I'm not sure what that means (what the problem was after flashing the custom ROM). You may have some words missing/wrong in the last sentence.
Flashing the custom ROM should work (seems that it was the real goal here). Did you also flash gapps (Google Apps) which is normally required for AOSP type ROMs? This (or trying a different gapps) is a frequent cause for an AOSP ROM not booting after flashing.
If you still want to return to stock, restore the stock TWRP backup from the collection, using the instructions and files on the following thread. Only need to do through Step 9, and reboot: https://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
Also, keep in mind best practice is to make a TWRP backup of your stock ROM, before trying to root of flash a custom ROM. If you did that, returning to stock would have been as easy as restoring the backup you made.

The problem I had with the Custom Rom was that I could not see my Sim contacts. It was a Rom Mokee 7.1.2 for HTC M8.
And I did not backup either the Rom Stock or the Custom Rom.
That's why I installed the Rom Stock 4.4.2 again
Can I install a RUU for HTC M8?

The description of events that got you to the current condition, gets more and more convoluted every time you post.
Not critical in this case (returning to stock is fairly simple, and doesn't rely that much on the history). But for other issues, conveying the information this way could be a real problem for those trying to help you.

You can. It would require relocking the bootloader. Then if you want TWRP, root or custom ROM, you will need to unlock the bootloader again after RUU. RUU will also wipe all data on the phone.
Must flash with SD card method, or using htc_fastboot
Not gaining much versus what I previously recommended, especially if you want to still have TWRP for root, custom ROM, etc.

I understand I was wrong at first to solve my problem. I got into that. I did not think well before applying the solutions. Thank you for your help.
So, if I understood correctly to flash the RUU,
- relocked the bootloader
- to be S-ON
- flash by SD Card or Fastboot
Should I install a recovery stock before relocking the bootloafer?

My comments/responses below in red font:

- relocked the bootloader yes, using fastboot command: fastboot oem lock
- to be S-ON It's not a requirement to be s-on, but it's your current condition. With s-off, the requirement to lock the bootloader is bypassed (and RUU still works).
- flash by SD Card or Fastboot Either SD card method, or htc_fastboot specifically. Trying to use the "generic" fastboot will fail since the RUU file is too large. IF you need further info, see here: https://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
Should I install a recovery stock before relocking the bootloafer? NO. It's not needed when doing RUU.

I managed to flash the RUU with your advice. Everything works well.
The only problem is the recovery. When I go into the recovery it shows me a red triangle and nothing happens. But I intend to install the TWRP.
Thank you for your help.

That isn't a "problem", it is working as it should. It's the stock recovery. Press vol up and tap the power button to show the recovery menu options (although not much you can do in stock recovery).

You're welcome. Please click the "Thanks" button for any post you found helpful.
Some advice and "best practices" as it seems that you've missed a lot of important info when trying to mod the phone:
1) Always research the most up to date info on rooting a device, before you start anything. Files are updated often, and using old methods can (and will) lead to a lot of problems. I know a lot of the info for this device is outdated, or not entirely organized. So feel free to ask questions if you are confused.
2) Always make a TWRP backup of your stock ROM, before doing any mods (root, custom ROM, etc.).
3) Always know how to return to stock, before doing the mods.
4) At least for this device, after installing TWRP, you don't need to root, if you are then going to immediately flash a custom ROM. In other words, you don't need root to flash a ROM. Most ROMs are pre-rooted But the few that are not, you need to flash root (SuperSU or Magisk) after you flash the ROM.
