Help! Accidentally hit the OTA upgrade while runing TWRP (bootloop)

I hit the "OK" on the OTA box without thinking, and only realized my mistake when TWRP came up after it started it's process.
I can get all the way back into the Launcher, but after about 60 seconds is reboots.
I'm guessing all I need to to undo one thing, or maybe flash a new/stock bootloader, but I don't really know where to start. I am coming from Samsung phones, so the terminology is rather different with HTC.
I've already made a backup of boot, system, and data, from within TWRP and copied it off the phone. I also quickly moved the OTA zip off my phone as well in order to keep a copy of it. Lastly, I can boot into "Safe Mode" (which I discovered by accident) and it doesn't do the reboot thing.
Any help at all is appreciated.
Thank you.
EDIT: Success!
Turns out I needed to re-flash my SuperSU binary from TWRP. I re-flashed the version I had first which actually removed the SuperSU apk. I re-downloaded it from Play Store, then flashed the 2.01 update. Runs like a charm.
Thanks to everyone for the help.

Hi,if you already backup your ROM before OTA,just restore it

I only did the backup after I got into the reboot cycle.
I haven't tried restoring it, but I don't imagine that it will work.

Can u please post your cid?u can find the stock nandroid backup that linked at my signature

No it will not work. Just delete the backup and save you the time and trouble messing with it. If you can grab a good backup from someone then you will be ok. Simply restore and all should be well. Then, make sure you remove your custom recovery prior to accepting the OTA.

Another method you could do would be to heavily modify the updater-script within the OTA. Removing the checks should suffice and thereby allow you to install the OTA via your custom recovery but it is easier said than done lol. A lot of lines to go through.

Ok, I need to do a bit of reading it seems.
I installed TWRP and SuperSu, but didn't modify my CID or get S-OFF (yet). I have a Bell Mobility version if that helps.

Thanks, I kinda figured the backup wouldn't help.
I would at least like to be able to restore the /data partition to keep my apps and such. I assume the /data backup I made after ****ing this thing up will not work for restoring /system files, but my data does matter to me.
I looked into the OTA zip file and found a /firmware.zip/recovery.img file. Will that recovery image work?

The recovery image is based for the new OTA. Won't necessarily be the same as what your device currently used but it should still work. If by any chance it does not then it is because of the Bootloader version you are currently running which is causing the problem. Which at that point you will need to grab the other stock recovery.img prior to the update.

I don't have your device so I can't really provide any links to assist even further but I ca build you a foundation to go off of. The logic with this stuff is relatively universal across common android devices for the most part.

Since you have the OTA, can you put the details of android-info.txt that you have inside it ?? This will definitely help you to find the right recovery/backup.

Have you actually seen this done? AFAIK stock recovery is required to install OTA; but perhaps I'm mistaken. In any case, its far easier to restore stock recovery if the intent is to install OTA. However, the current installed ROM must also have no system files altered, as this is also a requirement for OTA installation.
Another (probably easiest) way out of this loop would be to mount the memory, find the OTA file and delete it. The phone should then stop trying to find stock recovery to install the OTA (which is the cause of the bootloop).

@redpoint73, that is a valid question to ask. I have not seen any guides made available to the public however, I can vouch it works. I once did it myself many many many months ago once I did some extensive studies on how an OTA was applied. Though, I won't hesitate to mention that it's a tedious process and I wouldn't recommend it less it were your only absolute option since there are so many easier methods to use.

Good to know, thanks for the explanation. Interesting that custom recovery will actually work (technically) with an OTA, that its just security checks that keep if from happening.
As you mentioned, there are many much easier options to recovery; so what you mentioned is just a method of "last resort".

So, if those links are offline, do you have another source or just use the one I got with the OTA?

Did you try to just find the OTA file and delete it, as I previously suggested? This should get the bootloop to stop.

Yes, the OTA is no longer on the phone.
It's not really "bootlooping", it boots normally into the Sense launcher, then after about a minute it restarts. It's not stuck on the HTC logo or anything; it's more like a restart-cycle.

Were you on a stock ROM, or custom before this OTA mess started? My recommendation would just be to pick a custom ROM of your choice on the phone (either via adb push or on the removable SD) and flash it in TWRP and forget this OTA business. Making it more complicated than it needs to be, and OTAs don't really have any business on modded phones anyway, for the most part.

I was on stock Sense6. I had previously unlocked and loaded TWRP since I assumed I'd switch ROMs very shortly after getting the phone. I was coming from Samsung's world where running my own ROM was mandatory since TouchWiz was so awful.
The only thing keeping me from flashing a custom ROM right now is my data/apps. In my sleep deprived state, I didn't think to make a backup (or to not accept the OTA in the first place). If I can flash a customized Sense6 ROM and keep my apps/data then I will.

The phone isn't really working for more than a minute or so. So I'd just do a wipe and install a custom ROM. Something is broken now, so a clean slate is probably your best bet.

Yeah, I'm just trying a few last things.
I tried flashing the newest TWRP and the stock recovery.img I got with the OTA; no luck.
I still have the full OTA zip though... Is there any way for me to adb push that file on the /sdcard/ to force it to complete the update? That way I can just re-flash TWRP and SuperSu and keep my data.
Thanks for all the help.

[Q] Rooted phone and want to install OTA update

The OTA 4.4.3 update is now available for my phone, but I've rooted it, and I've read the horror stories so I'm not going to blunder blindly into this
My rooting experience went a little poorly - I thought I was doing the right thing by backing everything up on the phone first, using Helium. Unfortunately Helium simply did the backup onto the internal storage itself, so it all got wiped during the process anyway.
Anyway, I got over that, but now I want to install the OTA 4.4.3 update. So here's the things I've done which I think are relevant:
1. Installed TWRP recovery, as required for rooting
2. Have flashed the SuperSU program for root
3. AFAIK I'm still on "stock" - I haven't gone out to find any special roms etc
4. Had to reinstall the calc and flashlight apps as they were missing after the whole exercise (so many I'm not on stock, or they would be there?)
5. I have installed Xposed Framework and the Sense 6 tweaks and GravityBox apps.
6. I tried to uninstall some system apps (Facebook, Twitter, things I don't use) with a root uninstaller program, but every time the phone reboots they re-appear, so I think I need s-off to do that properly?
7. I've 'Disabled' the weibo app through the standard app info button
I understand I have to go back to the "stock recovery" in order to do the OTA update, but is there anything else in the above list that I need to do anything about?
Will going back to the stock recovery mean I lose all of the content on my device again, and have to restore it from a backup? If I use the HTC backup app to back up all my phone data on the rooted 4.4.2 I'm running, can this then be restored onto the 4.4.3 version?
Also is the problem I mention in #6 solved by going s-off?

Flashing back stock recovery you won't loose anything. This just happens during the unlock process if done with HTCDev.
Good that you are not S-Off and FB, Twitter and so on are still installed, as otherwise you wouldn't be abled to perform the OTA. An OTA is only going to run if the whole system is unchanged.
Only thing that's quite likely going to happen, is that you root is lost after the OTA. Tthus you would have to flash TWRP and the SuperSu again, after the OTA.

I thought it didn't matter if you were s/off or not, so long as recovery and OS were stock and CID matched (or were SuperCID).

It doesn't matter in general. But it matters in case that you used S-Off to uninstall system APPs Thus an OTA wouldn't succeed.
That's what I wanted to say in my post above
Sent from my HTC One_M8 using XDA Free mobile app

Wow found my answer already. Just to confirm. I'm in the same situation. Rooted. Installed twrp and su. Went to s-off with firewater but got the whelp message.
Got the OTA update in this morning. Tried installing it, went to my recovery so I tried to install it. It failed of course. Phone is still ok.
I'm just making sure I'll do this ok. Gotta go back to original recovery then install it or am I just better off going to a custom rom?
On my vivid, I used paranoid when it was available, used pacman for a bit. Also used the CyanogenMod. I know recommendation shouldn't be made but i know on my vivid there were lots of issues since there wasn't a specific team rolling out the roms but someone porting them from the specific team. Is there a team dedicated to this phone? If so are their roms leaps ahead of the ones ported over? Just looking at the downloads you can tell which one is the most popular, that doesn't always mean they are the best.
Thanks for any advice.

I would revert to stock recovery and get me this OTA. And you need a 2.22.xxx FW for some of the custom ROMs currently available.
It's the fastest way to update your firmware anyway
Alternatively you could try to perform an S-Off using SunShine and paying 25$ for it, as I did to flash the newest FW.

I had the Vivid as well and ended up with a 4.4.2 ROM which seemed to be the most current that was available at the time, but can't remember the name or the dev.
As for the M8, I've been on ARHD almost exclusively and think it's one of the best ROMs out there. I've tried Viper, MaximusHD, Renovate also, but always come back to ARHD.

I have the WWE edition and am currently with ATT. I'm considering their new update mainly to see if the new firmware/radio will give me better LTE speeds. The fw is 2.23 based. Will that be a problem if or when I return to ARHD which is on 2.22?

That's a really good question. Regarding ViperOne I could tell that running 1.8.0 (which was on 1.54.xx base) with 2.22.xxx FW worked flawlessly. So I would guess this should work just fine.
At least it's worth a try. Maybe better ask in the ROM thread.

Used arhd on my vivid for a bit. Must say it was an ok rom but lots of issues in general with all new roms on the vivid. Hardware too outdated. Maybe I'll give it a shot. Really leaning to a de-senced one.

Ok, that's encouraging.
My CID is HTC__621 although I don't think I need that for just flashing back to stock recovery. My version is 1.54.709.12, so I downloaded the matching recovery from here http://forum.xda-developers.com/showthread.php?t=2701376 and flashed it. I confirmed that the stock recovery was installed by booting to it and getting the red triangle etc.
Then I downloaded the OTA upgrade and told it to install. I didn't watch the installation progress, but eventually it went to the red triangle screen and finally rebooted. But I'm still on 1.54.709.12, so I take that to mean the OTA failed. When I go to system update, it checks and finds one available and offers to download it again, which I haven't done.
I'm wondering if 'disabling' the weibo program could have caused the update to fail? Or possibly I *did* actually uninstall a stock program or two that I mentioned at #6 and that's what's preventing the update?
Anyway, I made a complete nandroid backup on the external SD card before I flashed the recovery. It seems like the easiest approach now would be to flash a stock ROM for HTC__621 then do the OTA upgrade. After that, I could restore my HTC sync (the app) backup from the cloud, but if I wasn't happy with that I could recover the data portion of my nandroid backup?

In fact you are right. The OTA fails as something on the system has been changed that's critical to the OTA.
So I would back up the data on the phone I need, download a stock nandroid backup for your CID, install with twrp, re-flash stock recovery and perform the OTA again.

Ok, so I put on a stock nadroid backup for HTC__621, changed to stock recovery, but the OTA update is still failing at around the 30% mark.
Actually I've just noticed that the stock ROM I put on doesn't have the calc or flashlight apps, but when I originally bought the phone they were on there. I had subsequently installed them using the apps on this thread here: http://forum.xda-developers.com/showthread.php?t=2699906
But maybe that is what is preventing me from doing the OTA now?
Edit: Right, so doing some more reading, it seems that HTC included these 'stock' apps in the /data directory instead of /system, so when doing the HTCDev install, they get wiped. But there was a note in that thread saying that for the One M7, they would actually do a hash of those apps too and if they weren't there the update would fail.
Someone linked to this thread http://forum.xda-developers.com/showthread.php?t=2703759 which says the APKs in the first one were from the M7, and these are from M8, and it also included another one called Seven Digital (yet another bloatware app I don't care about, hence why I didn't notice it was gone). Anyway I installed those 3 apps, but the OTA update still fails at around the 30% mark. I notice that the thread says preload APKs for 1.54.401.5, but my phone is running 1.54.709.12, so if they really are doing hashing for all of these apps, the update might be expectly a slightly different version and therefore fail the hash check?

Resolved!
Right, posting as new post because I solved it!
I searched through the collection thread and luckily found someone else who has HTC__621 who wanted to do the 4.4.3 upgrade as well. ckpv5 stepped in to lend a hand with this post: http://forum.xda-developers.com/showpost.php?p=54598052&postcount=1514
The TWRP stock ROM he posted there includes the flashlight and calculator app, as well as another one that looks like it was missing - WeChat. So now the OTA update has applied as expected. :highfive
I'll suggest Mr Hofs remove the existing nandroid backup for HTC__621 that he has there because it isn't complete.

Weirdly after all that was done, now that I have 4.4.3, the calc and flashlight apps are again missing; no sign of WeChat either. So I'll probably have to go through this whole performance again next time I want to OTA update?
Edit: More findings. In installing Xposed Framework on my phone, it can't do the 'classical' install because of S-on, instead it flashes it through recovery. So I suspect this could have been preventing the OTA update as well.

Because you relocked bootloader when you did the OTA update. So those files were deleted when you re-unlocked bootloader after OTA done.
There's a TWRP backup for the latest here : http://forum.xda-developers.com/showpost.php?p=55097943&postcount=1744
Just a note : there is no need to relock bootloader to do OTA update.

Ok, at least there's an explanation for what happened, but I didn't at any point explicitly lock the bootloader. All I did was:
1. Flash TWRP recovery
2. Flash the ROM you provided
3. Boot the phone, going through the setup stuff to configure wifi etc
4. Booted to fastboot and flashed to stock recovery
5. Rebooted phone, downloaded and installed OTA update
6. Booted to fastboot and re-flashed TWRP, ran nandroid backup and then installed superSU when offered
At what point would the locking of the bootloader have occurred?

Re-unlocking bootloader is one scenario that may happen that remove the preload folder.
Restoring an old backup which doesn't have the preload folder is another scenario.
Anyway that is easily can be fix by pushing the preload folder from OTA zip to /data
then make a new backup for future OTA

Ok, well like I said, I didn't explicitly choose the lock the bootloader at any point, and the nandroid backup that you created *did* have the extra apps in there (I confirmed their presence at step 3 in my sequence).

Verizon LG G Pad 8.3 system update

I rooted this tablet last week (just rooted, I left it stock) and this morning I notice there is a system update waiting to be installed. I am reading Lollipop is starting to roll out in Asia somewhere now but I am in the US lol. I thought it wasn't possible to get OTA updates once you root? If I allow this to update will I get unrooted, would it even work?
I foolishly allowed it to update after checking in Supersu to not allow the root to be lost and now I keep booting directly into TWRP lol. How do I wipe this tablet from TWRP so that it is fully stock again (NO ROOT)? I see a factory reset option in TWRP do I need to include all the partitions in the advanced wipe or is just the normal wipe method enough? Or will this not work at all? I already tried to restore the phone using TWRP to my backup and that didn't seem to work.

Simply rooting a device doesn't keep it from TRYing to update via OTA. Rooting can prevent an OTA from succeeding, plus can hard or soft brick if you try to take an OTA, although usually only if you've gone beyond just rooting by installing a custom recovery or changing the contents of any partition besides Data by, fire example, downgrading your bootloader (aboot.img) or modem, running a custom kernel, debloating system apps, etc.
There are at least three variants of the G Pad 8.3. I have the VK810.4G, which do you have?
I know on the VK810.4G, Verizon just released a very, very minor update from LG build #23A to 24A. Still KitKat.

There's the main problem, you had a custom recovery installed. OTAs are applied with the stock recovery, that's why it (probably soft) bricked it.

You might not be able to fix it from TWRP. You could try @autoprime 's fix recovery zip available the same page his flash2 scripts are. You'll have to Google:
autoprime flash2

.
Otherwise, you'll have to restore to 100% stock unrooted and start from scratch. Two methods.
One is using LG's official Mobile Tool, which will download the latest official ROM in KDZ format (takes 20+ minutes to download) and flash it with your tablet in Download mode (probably with the tablet off, hold both up and down volume buttons in and while holding them, turn the tablet on.
I've got to go do something so hopefully someone else will help further or I can get back to you later, dont know when though.
Good luck!

OK now that I am up and running fine the system update message keeps popping up. This time I KNOW not to try and upgrade while rooted. Is there any way I can stop the tablet from constantly giving me the upgrade message? Can I do anything from TWRP to stop this?

Can I uninstall TWRP, keep root , do the update and then reinstall TWRP? If so how? Is there any other way around this issue, any way of not having the tablet continue to ask me to upgrade? Thanks BTW...

Yes, you can do that, but I don't know the steps. Others here do.
Why do you want TWRP? I thought the usual reason was to install custom ROMs (in which case you won't receive any OTA updates). If you just want to root, it's an unnecessary complication (as you have discovered).

Thanks Dean, and yes I do agree with you about it being a complication. I was always under the assumption if I rooted a phone that I needed to also use some sort of recovery god forbid I had an issue with the phone not booting up or something so I could possibly fix the issue, make a backup/install a backup etc. Maybe I will ****can it if someone will tell me how to do so without losing my data or root.

root problem please help

Hello everyone im new to this forum and i got a problem i think u guys can help me with.. . First of all i have to tell that i know nothing about rooting. Recently i bought an used HTC one m8 from a friend and had kitkat on the device. so i tried to check for updates. but i saw the option is missing. so after few minutes i get to know that this device is rooted, when i see the information about the phone. there is an app called super su and when i open it it says "there is no super su binary installed and super su cannot install it.....( ithink you guys know the rest) so i tried two days googling the problem and did everythin i can. but no results. root checking apps say that this device is not rooted but it is.. (some kind of half rooted i think ) so can anyone please be so kind to help me.....?. (sorry for my bad english if it is )

Then that is the stock TWRP backup and stock recovery you want to restore, from the thread I posted. After you restore to stock, it should OTA update to Marshmallow.

In s-on devices, it is not giving access to stock recovery directly. The first coming exclamation mark is normal. In that occasion if you want to access recovery; while pressing power button, press volume up. However you don't need to go to recovery.
1) If your bootloader is locked, unlock it. http://www.htcdev.com/bootloader/
2) flash twrp (TWRP 2.8.7.0)
3) restore backup (4.16.401.13)
4) flash stock recovery (4.16.401.13)
5) check updates
(the thread given by redpoint73 includes information A-Z to stock)

thank you both redpoint73 and umesh. Really appreciate the help. Im gonna try this and return to you if i have any problem

That is the stock (official HTC) recovery; from there you can press power+vol up to show the stock recovery menu options. But as a previous reply mentioned, stock recovery isn't going to help you (restore stock TWRP backup, etc.). For that, you need to unlock the bootloader (if not already) and install TWRP custom recovery.
The bootloader screen, near the top, will indicate whether the bootloader is LOCKED, RELOCKED or UNLOCKED. If LOCKED or RELOCKED, unlock it as mentioned in Post #9 above.
My guess is that the previous owner restored stock recovery in a botched attempt to return the phone to stock. By "botched" I mean they didn't properly restore the stock ROM to remove root. But following the guide I linked previously will do that properly.

The version we told you to restore is not for a demo version. I don't think you restored as you were advised, at least not properly.
Also, factory reset only wipes user data, it doesn't affect anything with the ROM; and you should not be mistaken in thinking it would.

Help – I'm lost. New to HTC and quite confused about flashing/rooting/...

Hey there,
I've got my first HTC device some days ago (-> HTC 10), but coming from a Nexus 5 where things are handled differently, I'm currently quite confused on how all of this works with my HTC 10.
I'd like to apologize in advance if the following questions seem to be stupid or unnecessary, but I'd like to use my device to the fullest and therefore I need your help.
My device is not branded (as far as I can tell) and I've already unlocked it via the steps on htcdev.com + I've installed TWRP + SuperSU (thanks to my previous knowledge with my N5 this was somewhat easy).
Now I got my first OTA update and this is when things got complicated. Several questions popped up and I tried to answer them myself while looking over here, but after reading all those threads I'm even more confused than before :/
My questions are the following:
1) Is there any way to manually update your device with the newest OTA update WITHOUT losing any data? (see question 2)
2) Do I need a microSD card in order to do so? I've seen several YT videos where they did a backup of the current system, but there still was a data wipe after flashing, so why even bother doing a backup at all?
3) My device is unlocked but with S-ON. Do I need S-OFF after all? As far as I can tell I don't need this, but is there any scenario I'd probably need it? (see question 4)
4) I'm thinking about getting a custom rom (Leedroid seems to be pretty decent). Can you recommend any of those custom roms and do I need S-OFF in order to flash them?
5) S-OFF + Locked or S-OFF + Unlocked? What's the difference? Any issues with the warranty?
6) If I do use a custom rom (e.g. Leedroid), is there also a way to update it to further versions without losing any data?
7) Where do I get the latest firmware for manually updating my device? I've already found a thread for it (http://forum.xda-developers.com/htc-10/how-to/stock-stock-collection-recovery-ruu-ota-t3359297), but my current firmware (1.90.401.5) or the one for the OTA update that already popped up (1.95.401.3) isn't listed over there. [EDIT: found my current firmware. Do I need to flash to it in order to do the OTA update?)
8) One last general question: as far as I understand it, unlocking your device is also the same as debranding it? I'm not sure if I'm mixing things up when reading about this. Is there any way to see if my device was branded before I did unlock/root it though?
I'm completely fine with losing my current data if that means that I can set it up my device in such a way that I can avoid any further data wipes when flasing/updating.
I'd be absolutely grateful if someone would answer those questions and help me to understand all of this.
Greetings,

1) Yes..you can apply the OTA manually, which won't flash the firmware image in the update but you can then find a no-wipe version of the new firmware on xda and flash it. Check out the faq in the twrp thread
2) for flashing firmware packages generally yes its better to have an SD card but I *think* it's possible to do it by issuing fastboot commands
3) s-off is needed if you wanna flash a new firmware I believe
4) you don't need S-off to flash a new ROM that's compatible with your firmware. Leedroid should work for you (this answer can be easily found by checking out each ROM thread and reading the Prerequisites section)
5) yes, most of the time you can "dirty flash" a new version of the same rom on top of the old one without wiping. If any issues pop up, or if it's a new base with large differences, then a wipe is needed. You can usually tell if a wipe is required by checking out what the developer says in the thread when a new updated is posted
6) I'm sure it's in a thread somewhere, you gotta search (I think sneakyghost's thread might have them)! And again you need S-off if you wanna flash firmwares

not an expert but here's my thoughts...
1) Is there any way to manually update your device with the newest OTA update WITHOUT losing any data? (see question 2) Yes. But if you want official update from HTC or your carrier via OTA you should be on stock. If you're on custom ROM, you can always dirty flash. But updating to a newer build, ROM dev sometimes recommend a full wipe
2) Do I need a microSD card in order to do so? I've seen several YT videos where they did a backup of the current system, but there still was a data wipe after flashing, so why even bother doing a backup at all?
SD card is not a requirement but is recommended since a full back-up size is ranging from 5gb-10gb maybe more depending in how many apps you installed. Backup is also recommended so you can always go back/restore your working ROM in case you messed up updating.
3) My device is unlocked but with S-ON. Do I need S-OFF after all? As far as I can tell I don't need this, but is there any scenario I'd probably need it? (see question 4). You need s-off mostly on updating your firmware or converting your device to other carrier or if you want to be unlocked. Right now you can flash any custom roms you like since we do not have a major update yet eg.1.x to 2.x. Once 2.x firmware is released, You can easily flash this firmware. But if you're S-ON, you can only update your firmware via official OTA from your carrier or if @Sneakyghost provide specific firmware for your carrier (matching cid and mid) in this thread else you're stock at 1.x firmware and ROMs that will only work on that specific firmware.
4) I'm thinking about getting a custom rom (Leedroid seems to be pretty decent). Can you recommend any of those custom roms and do I need S-OFF in order to flash them? See my answer in #3
5) S-OFF + Locked or S-OFF + Unlocked? What's the difference? Any issues with the warranty? If you're S-off you can always revert back to S-on and return to stock for warranty purposes.
6) If I do use a custom rom (e.g. Leedroid), is there also a way to update it to further versions without losing any data? Yes. see also #1
7) Where do I get the latest firmware for manually updating my device?

[EDIT: found my current firmware. Do I need to flash to it in order to do the OTA update?)See @Sneakyghost thread linked in #3. Firmware updating can be done via OTA or via fastboot(firmware zip can be downloaded) or full RUU (updating both ROM and firmware).
8) One last general question: as far as I understand it, unlocking your device is also the same as debranding it? I'm not sure if I'm mixing things up when reading about this. Is there any way to see if my device was branded before I did unlock/root it though? I think you meant sim unlocking here?? Generally, "unlocking" mostly mentioned in xda refers to bootloader

On the device itself, I don't think so as long as you return it in full stock state. But if I remember correctly HTC dev requires you to provide your imei when requesting for unlock token bin file used to unlock bootloader, So if your unlock you device via HTC dev they have your imei in their record. They know that you already unlocked your device and warranty is void already.

Take a look at this link. It provides you a complete explanation between ROM and Firmware.

Click to expand...
Click to collapse
Updating via official OTA usually updates ROM and firmware.
Installing a custom rom does not update firmware. Yes, it only alters ROM. But your ROM should always match your firmware at least the first digit of the firmware version (eg. 1.xx). For instance Android N (firmware veraion to be 2.x) arrives and LeeDroid updates its ROM to this, to be able to flash this latest custom rom, your firmware should also be at latest 2.x firmware else it will not boot. In this case, you need to update your firmware either via OTA, Fastboot or RUU.

Do you mean like this? (found in another forum):
1. First step is to unlock bootloader:
a) If bootloader unlock is turned off on your phone, you need to turn it on first:
- Boot to Android OS and perform initial setup if necessary
- Go to Menu -> Developer settings and tick "Enable OEM unlock"
Run XTC 2 Tool and open "Bootloader unlock" tab, follow instructions to unlock your bootloader.
2. Reboot to download mode, open "HTC 10" tab and install twrp recovery, you can get it here:

On the device itself, I don't think so as long as you return it in full stock state. But if I remember correctly HTC dev requires you to provide your imei when requesting for unlock token bin file used to unlock bootloader, So if your unlock you device via HTC dev they have your imei in their record. They know that you already unlocked your device and warranty is void already.

Yeah, I've done it this way. Sucks. But maybe it's not this bad at all. As I'm trying to be safe anyway, I probably only need to make use of the warranty if I'd accidentally drop my device. Those cases are still valid for warranty as far as I can tell (extract from the htcdev.com site: 'Please understand that you will not be able to return your device to the original state and going forward your device may not be held covered under the warranty for all claims resulting from the unlocking of the bootloader.'). Do you also know anything about this?

Thanks, will look into it.

Updating via official OTA usually updates ROM and firmware.
Installing a custom rom does not update firmware. Yes, it only alters ROM. But your ROM should always match your firmware at least the first digit of the firmware version (eg. 1.xx). For instance Android N (firmware veraion to be 2.x) arrives and LeeDroid updates its ROM to this, to be able to flash this latest custom rom, your firmware should also be at latest 2.x firmware else it will not boot. In this case, you need to update your firmware either via OTA, Fastboot or RUU.

Good to know. So in order to use the latest Leedroid and get rid of that OTA update notification, I should do the following:
1) Go back to stock (flash via RUU)
2) Hardware S-OFF (see above)
3) Flash latest OTA update
4) Custom Recovery again (TWRP) + Root (SuperSU)
5) Install latest Leedroid (have to read about it first, but afaik I have to install the zip of it via TWRP)
6) done
Is this correct or are there any mistakes?
And thanks a ton, you've helped me so much already!

If you are stock with only SU, then this is how I've gone about installing OTAs without wiping data:
1. Download ota (Settings>About>Software Updates) and move downloaded OTA from /data/data/com.htc.updater/files to sd card
2. In TWRP restore stock 'System Image' and 'Boot'
3. Reboot to Downloader
4. Flash stock recovery (fastboot.exe flash recovery xxx.img) --> can use current ota.zip > extract firmware.img from zip (if using 7zip -> rename .zip to .rar to extract fw)
5. Reboot to stock recovery
6. Install OTA in stock recovery
7. Reboot to Downloader
8. Reinstall TWRP (fastboot.exe flash recovery twrpxxx.img)
9. Backup stock 'System Image' and 'Boot'
10. In TWRP reflash SuperSu/Xposed/etc

This sounds very convenient and not far too different than what I was used to with my N5. Guess I'll give it a go! Already found a way to disable the HTC lock screen http://forum.xda-developers.com/htc-10/help/disable-htc-10-lockscreen-t3418108 (which is annoying especially when using a different launcher as the lock screen background is still the one from the stock launcher). Only thing bugging me now is that BoomSound notification, but I guess I can live with that

may look at installing XPosed as they have a module "XNotifications" that lets you hide any type of notification

Will also look into this. I've used Xposed on my N5 but wasn't sure the HTC 10 is already fully supported (have read something about that, but those threads were already 3-4 months old). Thanks!

So I'm trying to do the step-by-step instructions from yankee1390 because I guess that's the easiest way for me to handle things. Now I've already got my first (and hopefully only) issue with it: I did no backup when I first installed TWRP and before I've rooted my device. So in order to accomplisch step 2) (restore stock system image + boot in TWRP), can I use the files from the RUU provided here -> http://forum.xda-developers.com/htc-10/how-to/stock-stock-collection-recovery-ruu-ota-t3359297?
I've found the one matching my current firmware (1.90.401.5), so is it ok if I use those for step 2?
And by the way, I guess I have to do a backup after every OTA update (and before rooting) so I always have the right files for restoring, huh?

Link didn't work on my app so can't confirm if that will work. However any TWRP stock backup that matches your current version should work. RUUs will wipe your data if you use them.
Definitely good idea to backup after each ota before modifying system partition to make next ota easier. Though usually someone on here can provide a backup if you don't get one.

I know that app by name, but never used it. Will take a look into it

If you mean OTA notification from HTC, most of the custom ROMs already disabled that, I believe. And they provide you with their own OTA update (Not all, some do. Like ViperRom)

This is correct but there is an easier way after you s-offed.
1. Download the latest firmware.zip, if you're not on the latest yet. Flash it via fastboot commands in download.
mode. Instruction is available in the link I provided earlier in @Sneakyghost firmware thread.
2. Flash TWRP.
3. Download your desired custom ROM (LeeDroid). This is in .zip file.
4. Reboot to recovery, wipe data/factory reset then flash the LeeDroid.zip. Just follow the instructions in aroma.
by the way, if you'll flash firmware.zip make you select the matching CID and MID of your device. You might end up bricking your device flashing a wrong firmware. If you can provide me your CID and MID, I'll link you to the correct firmware for your device. To do so, reboot to bootloader and type the following commands in cmd, remove your IMEI and SN and post the result here.
And thanks a ton, you've helped me so much already!

I never done updating software via HTC official update. I don't know but for me I don't see any reason sticking to stock ROM. There are a lot of custom ROMs out there tweaked for better performance and battery life. They are also always updated to latest build.

I love using stock android, that's why I also loved using my Nexus 5. I used CyanogenMod with another device many years ago but I am willing to use a custom ROM for my HTC 10, but only after I already know how it feels with stock ROM. So I will stick with it for several weeks and see how it feels, and when I'm farmiliar with it, I will switch to a custom ROM So thanks a lot, you've given me a lot of information I will still need for further experimenting with my phone!

Piggybacking on this thread because my new-to-me HTC 10 is coming in the mail and I'm planning what to do with it. It is already bootloader unlocked and s-off. I would like to use Leedroid, ElementalX, Magisk, and Xposed.
I've never had an HTC device so I just want to make sure I'm doing this right. So I think this is what I need to do:
1) Flash TWRP via ADB
2) Flash SuperSU in TWRP
3) Flash everything else...Leedroid, ElementX, Xposed, Magisk. In that order? Can I flash them all at once (just keep adding zips to the TWRP list) or do I have to boot between each one?
Xposed is more important to me than a custom ROM, because I need to use Amplify and PowerNap to improve my battery life. Would it be better just to stay on stock instead of Leedroid?

@jrbmed08
TWRP is flashed via fastboot, not ADB.
No need to flash SuperSU via recovery since LeeDroid has root already.
You can flash everything at once.

When I said stock ROM, i meant stock HTC ROM and it's not stock Android. It's a skinned android called HTC sense. . If you want a stock android to run in your HTC 10 you can flash a AOSP based custom ROM.

Ah yeah, sorry, fastboot is what I meant. Thank you! I haven't had an unlocked bootloader in quite a while (was using TWRP and Sony stock-based ROMs on a locked Z3c), so it will be interesting to flash kernels and such again.

I think with firmware they mean bootloader. But nobody gave me a good answer till now...

not only bootloader, it contains everything. radio.img and any other thing. "low-lewel-stuff", kernel etc, recovery (if stock signed firmware, which is not modded/removed). there are many important things inside.
but firmware is meant for every device the same. it contains everything so that this device can run/work properly.
