[Q] Cant Upgrade to Lollipop (Error Msg included)

Hi Everyone
I've got a HTC One M8 which I bought off a forum which was already rooted and runs GPE.
Everything has been fine, but I've been receiving the notifications to update to Lollipop, which I'd like to do. I click on the update and it downloads it. When it goes to install the update the phone reboots and boots into TWRP. I click on install and select the update zip. but I then get an error, please see the attached images.
Can anyone shed on any light on whats going wrong?
THanks in advance fo all replies

1) Its the update to 4.4.4 that is rolling out for AT&T, not 5.0.
2) You need to re-install stock recovery in order to install OTA. Also, the system needs to be stock (stock ROM). Root is okay (although you will lose root). Unlocked bootloader is also okay.

Hi thanks for the reply.
I'm based in the UK, so not sure that applies to me?
When I bought the phone the bloke said it would receive updates OTA. I'm hoping someone can explain the error messages in getting and help me upgrade to 5.01.
Thanks

Is it the AT&T version? This is the AT&T specific forum section.

Sorry, no it's not an AT&T version.
How do I go about getting it moved to the correct forum?
Thanks

I'll notify the mods to move to the correct section.
My 2nd point from Post#2 above still holds. You can't install an OTA with custom recovery (TWRP). You need to install stock recovery for your version from here: http://forum.xda-developers.com/showthread.php?t=2701376
Also need to restore to stock ROM, if its been altered by root in any way.

[Q] Best way to upgrade US i-467 (AT&T) to 4.4.2

Sorry for the post, but I've looked elsewhere and searched can't seem to find the best, fastest, and easiest way to accomplish this.
1. I have an AT&T GN8.0 (SGH-i467) on 4.1.2. Build CAMF2. I'd like to upgrade to 4.4.2 The device is rooted, with locked bootloader and stock recovery. I also have an AT&T Pay-as-you-go SIM installed.
2. I'd like to end up on 4.4.2 rooted. I have never been offered the 4.4.2 upgrade on my device and I'm not sure if it's because I have a PAYG sim or it's cause I'm rooted.
3. I'm not afraid of Odin, download mode, etc., so if anyone can help me figure out the best way to get myself upgraded, I'd appreciate it. If you want to point out some posts, threads, etc., that can help, that would be great too, but I've scanned all of those and it all just gels together to where I'm not sure what's what anymore.
Thanks.

Don't try to update via OTA with a rooted ROM as it may cause a softbrick. I recommend unrooting and trying to update or flashing a stock ROM from sammobile.com and then try to update to KK.

Thanks, that make sense.
Going back to stock shouldn't be a problem, but any thought to if I can update to 4.4.2 with a PAYG SIM? If not, is there a flashable file and method that you can point me to?

It has been my experience with various phones that OTA updates should work regardless of whether a sim is or is not inserted.

Just need a bit of help getting going

So Ive searched around and I just can't find a definitive answer so here is what I got.
I understand that this here; is how you use marshmallow with the new bootloader unlock and root: http://forum.xda-developers.com/not...t/howto-bootloader-unlock-upgrade-to-t3398144
I also know that I have to do this exploit first to unlock the bootloader: http://forum.xda-developers.com/note-4-verizon/general/note-4-verizon-bootloader-unlock-t3358913
My issue is I ended up getting forced OTA 2 weeks ago. So my current question is, Do I have to roll back to lollipop? Is root/unlock even possible for me? If so, How do I do that since I haven't rolled back before. Its been a while since I've been into rooting/roms. Is there a link to doing it for marshmallow to lollipop? Also what about the firmware?
Current Stats:
Model: SM-N910V
Baseband: N910VVRU2CPD1
Android Version: 6.0.1
Build: MMB29M.N910VVRU2CPD1
Kernel Version: 3.10.40
I just need an answer since Ive been reading threads the last 2 hours. Its confusing since the titles of most are how to unlock bootloader THEN goto marshmallow. Thanks Guys!

I think I solved it myself. Looking like I'm effed with this bootloader. Since I don't think its rootable or unlockable.

You can try to roll back to 5.1.1 by flashing the full firmware (thanks, hsbadr!) using ODIN. You can unlock the bootloader on this version.
The question is, will your phone let you. In another thread, the success rate appears to be something less than 100%. I don't know what the harm would be... if you can't do it, ODIN will likely fail. At any rate, the attempt is on you. I can't be responsible for what happens.

Just frustrated right now trying to get Wifi to work. It looks like its suggested to try Flashing MM Stock, Reroot and Re-unlock bootloader here:
http://forum.xda-developers.com/not...t/howto-bootloader-unlock-upgrade-to-t3398144
Then use TWRP after all that.

Just make sure you're paying attention to what you're flashing. There are only three roms in the verizon development section that are able to utilize the 6.01 bootloader and modem. JASMINE ROM, PAULPIZZ 6.01 Beta and Cm13. The other roms are ports based on 5.1.1 so you may need to stay on the previous setup until more roms are updated
Tip the OP usually states what works/does not work and updates when things are fixed . The information changes quickly so sometimes you may need to read the thread from the end back to the beginning to see if your issues have been addressed

It was actually super simple once I found the thread on how to go back to 5.1.1 then how to take that and go unlocked w/ marshmallow chain. Last thing to figure out is disabling OTA on Jasmin ROM

Software Update ATT.

Hello,
I updated my HTC One M8 first time since I first buy the phone. My Original ROM was 4.4.2 and I updated to 4.4.4 (OTA update ATT). I rooted phone and did S-OFF. But recently I changed ROM back to 4.4.2 using hard reset and install back very first original factory ATT Rom (4.4.2). Now when try to update my ROM through ATT OTA, it gives me message to "Wait (24 Hrs)" I already wait for 4 days, clicking back on Software Update. Also my MMS service is not working ( My MMS service was working before with both 4.4.2 and 4.4.4).
My questions is " Is there anything which I have to wipe or clear to make it completely fresh like brand new first time OS ?"
Thank you so much for reading my post!

Since you have an AT&T branded M8, and are S-off, you can just use a RUU to switch versions. No need to take an OTA (other than to preserve data, but it sounds like that isn't an issue if you have already downgraded)
The most recent is here: http://www.htc.com/us/support/rom-downloads.html
Older versions are available, but I don't have a direct link for them.

I would appreciate if you can attach link for 4.4.4 RUU file or .zip file(Install from TWRP). I dont like Marshmallow.

Check AT&T General section forum... it is available under stickied thread

Question on mismatch of OS version in download mode compared to sw information

Hey everyone,
Apologize if this is something that has been asked before, haven't been able to find much information on it using search. Also still a relative newbie to android, so hope you folks will bear with me. I'm seeing the OS version in download mode showing as OS-3.36.709.3, while the software number in software information shows 4.30.617.12. Is this considered normal, or did I mess something up?
I previously had Marshmallow on my phone, and used TWRP to install the developer edition of Nougat. Was trying to do OTA, which unsurprisingly didn't work with TWRP installed. My plan is to reflash the recovery.img, but I'm unsure whether I should be using the recovery.img for 4.30.617.12, or the one for 3.36.709.3? Is there something I should do to get the versions aligned properly? Trying to make sure I avoid bricking the phone

The easiest solution would be downloading the latest version of the rom that you installed in the past and flashing it via TWRP.
Some advices: Please read the ReadMe thread. It explains why the version numbers differ (e.g. in the RUU section). In addition it will explain to you, that installing OTAs with TWRP actually is possible (c.f. the OTA section) but not in your case. Even with the correct stock recovery for your phone (the 709 one) you wouldn't be able to achieve your goal. You're trying to install an update for a completely different firmware than the current one of your phone. That's not possible. OTAs are incremental. That means you need to be using the firmware that the OTA is supposed to update (4.30.617.12) and not 3.36.709.3. You would need to convert your phone if you want to install that update.
You might want to read the article that I called "the difference between rom and firmware" in the further reading section of the ReadMe thread, as well, after you finished reading the ReadMe thread itself.
Be aware that it's always best to use a system that has the same version (or at least the same mayor version - e.g. 3.x for marshmallow or 4.x for nougat) as your phone. This way you can be sure that system and firmware are optimized for each other. Mismatches can cause unforseen side effects like battery drainage, lags or bugs.

I read the ROM vs. firmware article, and also based on your last comment, I think it would be best to align the firmware and ROM versions. If I'm understanding things correctly, I either need to flash the firmware to a version matching my ROM (4.30.617.12) by following the steps in the 's-off firmware flashing thread', or else I need to go back to a 3.36.709.3 rom and use OTA to update the firmware/ROM. If I use TWRP to update the ROM, I'll still be stuck with an older firmware. Is my understanding on this correct?
I originally go the phone second hand, and am not sure what ROM was on it to begin with. Had previously tried to get it back to stock to update to Nougat via OTA, but kept getting the your device software has been modified regardless of what I did, so ended up using TWRP.
P.S. will make sure to put questions in the right forum in the future.

Then the phone had been modified before you got it. Since android 5 google is using block-based OTAs. That means re-flashing the stock recovery isn't sufficent if you want to update your phone and modified it, beforehand. You need to restore a completely untouched system image.
Check the ReadMe thread. The RUU section as well as the TWRP section II should contain the files and instructions that you need for restoring the OTA function of your phone. It's up to you which of the methods you prefer to use.

Appreciate the information and the advice. Decided to RUU back to a 3.x version, and use OTA to upgrade to Nougat. Took a lot of updates to get it to the latest version, but everything is working well now
