I want to go from TWRP recovery to stock recovery so I can take the latest OTA and update to latest version of viper. When I try to flash stock recovery through fastboot, I can't reboot into recovery, but I can boot into the my current ROM. After I flash TWRP back, I try to RUU using the RUU zip, but it says that "it doesn't have enough space."
My 2 questions are
What steps should I take to return to stock so I can update the firmware?
On my fastboot menu, it shows the OS - spot as blank, what should I do about that?

Have you tried putting the RUU on an SD card and booting into bootloader mode and letting it automatically detect it and install it? This would usually take a few minutes all the way up to 20 minutes, just incase you were expecting something quicker and may have exited out of it previously.
To my knowledge the RUU would/should fix the OS issue as it installs everything again back to stock.

I have had this exact same issue on the last two M8s I've had to RMA, so I have to return them to stock/locked/S-On. I had to use the SD card option that SilentShadows is referencing above to get the stock bootloader on my previous phone. But I can't find my old SD card that I used before now, so I went back to this thread to see if anyone had posted a solution to it from the last time I posted in there asking the same question you have. I found this nice post which may explain it for me at least. I was using my laptop that only has a 120GB SSD that stays pretty full, so that may have been the issue for me. Make sure you have at least 2GBs free on the PC/partition you're flashing the RUU from.
I have a Nexus 5 running stock Lollipop (5.0). My phone is rooted and has CWM Recovery installed. I've tried to update OTA to 5.0.1 twice now. Both time, it has downloaded the update and rebooted as usual. Then CWM Recovery prompts me to install the update. After hitting "Yes" it appears to install the update and then informs me that root may have been lost. I've tried saying both "yes" and "no" to fixing that. In both cases, I've retained root, but my phone remains at 5.0 instead of 5.0.1.
From my limited rooting knowledge, I can see flashing the factory image would be the most straightforward way to updating, but obviously that would wipe my phone. Titanium can only back up so much. Plus I want a simpler way to do this in the future. To me, it seems another solution would be to revert to the stock recovery and have that install the update. However, I don't know how to revert to the factory recovery without flashing the factory image. All of that being said, what is the best way to OTA with a stock ROM but a custom recovery?

It's been said about a million times on this forum:
You have to be stock or the OTA won't work. Stock system, stock recovery, stock kernel etc. Extract and flash files from the factory image just don't flash the userdata.img file.

Thanks. I don't spend much time on here and I didn't see a post that gave me something concrete.
I'm currently downloading the 5.0.1 factory image from Google, but since it's such a large file and my internet is quite slow, it's going to be over an hour yet before its finished. That being said, I downloaded the .zip version of the OTA update as linked on phandroid and attempted to install it with CWM. Dispite the fact that I'm running Lollipop, I got the following error. I've shortened the name of the .zip because its quite long.

I flashed the factory image for Android 5.0 a couple of weeks ago so I don't see any reason why it should see the KRT16M fingerprint. Any ideas?
EDIT: Never mind. Looks like this has the same effect and won't work if I'm not completely stock. I'll just wait for the factory image to download and flash that. Correct me if I'm wrong.
I am getting the same error.

I actually tried reverting to stock recovery using Flashify. Though it shows success but when I try to run the update, it doesn't get past the recovery mode, android with the red exclamation mark. Not sure where I am going wrong with it specially when I have been flashing since last 3 years.
Ok, let me start by saying that I'm fully capable of updating my phone with a computer, I'm just hoping there is a better way. So far every time I've downloaded a new firmware, update the flash-all.bat and run it, something will fail towards the end of the update and the only way I've been able to successfully update is by using one of those tool kits (forget which one, it's on my computer). I'm not that concerned about all of that with this thread. I'm wondering if there is a way to do it without a PC.
I'm on NMF26O (root, ElementalX, etc) and tried flashing Pure Nexus over the weekend. Since it's based on NMF26V, I kept receiving an error on boot about updating my vendor.img. So I downloaded that firmware, extracted it, and flashed the vendor.img in TWRP. That led to a plethora of other issues that I couldn't resolve by flashing the boot.img, reflashing the rom, ect. Several hours later I ended up flashing the boot.img and vendor.img for NMF26O, restoring my backup, re-installing Elemental, and rooting again.
Since these updates will be coming out every month, and roms will always be based on the latest update, I feel like I'll be pulling out the computer every month, downloading the updates, modifying the flash-all.bat, and running it through the tool, just to be able to update my rom. The first time I forget to update flash-all.bat, I'll lose the 60+ GB's I keep in internal storage. There has to be an easier way. TWRP is capable of flashing images. Has anyone been able to update without using a computer? I don't care if my radio is out dated, or something is mismatched as long as my phone works as intended.

Not sure why you ran into issues with PN. You need to be on the latest build NMF26U. You can flash the ROM via recovery. Then tku have to reboot once and go back to recovery and flash the V vendor image because the ROM is based on NMF26V. Each time a new ROM comes out on a new build you can flash in recovery.
If your talking about flashing stock OTAs via recovery that's not possible yet. No need to do this if you're going to be using custom ROMs though

I'm on NMF26O. What's the difference between it and NMF26U and why would the vendor image from NMF26V work with NMF26U but not NMF26O?
Seems like all you would need is the /system from the rom, the vendor image, and maybe the boot image (or a custom kernel). I think I'm missing something here.

If you install PN its based on NMF26V. So unless you are already on that then you would need to flash the ROM, reboot back to recovery, then flash the NMF26V vendor image.
I'll play devil's advocate here... Yeah there is an easier way, use your Pixel stock and take OTA's. Enjoy a phone that always works, with or without a laptop!
I understand my audience and realize this isn't a popular mantra here but I felt exactly like you did with my 6p and vendor images. I got to the point where I sacrifice root now just for my own sanity. My phone works for me, not the other way around.
What I do is side load the full OTA ( which you can get from the same place you get the factory images ). I only use the fastboot boot version of TWRP so that my stock recovery stays in place. Then all you have to do is boot into the stock recovery, adb side load the OTA file and re root. Then you're fully up to date without worries of your data being wiped :laugh:!
( Although if you look in the flash fire thread from Chainfire, he's working on a version that will let rooted pixels flash otas like normal ones :fingers-crossed: )
I think you guys are missing the point. I have no desire to ever be stock, which rules out the possibility for an OTA in any form.
What I'm trying to figure out is exactly what is necessary to make a custom rom (based on the latest OTA), work if flashed over an older build, without first somehow applying the full OTA. Or is it impossible?
On just about every other phone I've owned, we could piecemeal the files needed for minor updates, along with a custom rom. The only time we'd have to flash a full update is for major updates ( 4 to 5 to 6, etc).

Ok, I figured it out. Just download the OTA.zip (not the full firmware), flash in TWRP, immediately flash TWRP again, and reboot.
I'm now on nmf26u.

I don't think we can just flash OTAs in twrp yet. Haven't heard of Antone doing it. There is a beta Flashfire out that I guess works to flash updates. J have it but haven't needed to try it cause I'm running PN and DU

I've done it several times tonight. Went from O to U to V, flashed Pure Nexus, screwed up the rom, restored to O, then O flashed back to U and V.
Just flash it like a rom in TWRP RC1. Make sure you flash TWRP again before rebooting if you want to keep it.

I'm thinking about unlocking my bootloader (well I will eventually, it just depends on how long I can last without root), but I've forgotten, is it still possible to take OTA's after you unlock your bootloader?
Thanks
Probably not.
Why shouldn't he be able to. Up until now the last four HTC devices M7, M8, M9, and 10 all received OTA updates even though the bootloader has been unlocked. There's just one new thing which startet with the change to Block-Based-OTA updates. An OTA won't install as soon as you change anything on the system partition (meaning that even mounting r/w in TWRP causes this!), due to a change in its md5 checksum.

Wait, so if I flash magisk, I won't be able to take OTA?
Dang. If I just flash the stock recovery, will everything work, or will I have to restore to stock and take the OTA, then re-root?
When you unlock, then flash TWRP, first thing you do is Keep System Read Only. Then make a backup of System Image, boot image. When its time for OTA. restore system image, boot img and flash stock recovery. Reboot and then take OTA. You can now fastboot boot TWRP from download mode to make a backup of stock recovery(before flashing TWRP).

Since TWRP can flash OTAs (firmware part of OTAs needs to be flashed separately via fastboot), restoring (and backing up) stock recovery is not mandatory.
Do you think Sunshine will come to U 11 or it's un-crackable?

Thanks! For some reason though, when I tried to fastboot boot twrp, it would flash successfully but hang on the rebooting part. I have no idea what was going on. Pretty frustrating.
No laughing now- I'm on an old Galaxy s4 & U11 seems like my next device, VZW is too much & Sprint has a 1yr free program. I have rooted B4, & used Odin, but I got into other things & I don't recall how Fastbooting works… PLS help the once again Fastbooy noob & explain. Since the Sprint program requires you bring an already-paid-for 'bring your own phone' this is a BIG up front investment & I can't imagine going w/out Root/TitaniumBU/ or twrp to save images to pull my coals out of potential fires… TIA, oldwolf
IMHO, fastboot commands and such to get TWRP installed is waaaaaaay easier and faster than ODIN. I actually try every few phone generations to use a samsung device, but the pains of doing updates and such through odin isn't worth it to me. Pretty much you can unlock your phone through HTC.dev and then with the bootloader unlocked you can load your own recovery like TWRP. they walk you through all the steps and everything.
tacotoy, thanks for the reply; but what constitutes a FB command, & fm what program & in what status of android boot is it run? tia, oldwolf
Yeah, lost... New VZW OTA out today, but since I'm unlocked with TWRP, won't install. Trying to find the zip in the cache so that TWRP can install it, no joy so far, re-reading the TWRP thread.

just google Minimal ADB and Fastboot. Download the lastest and place all your zips and images in that folder. It is a standalone program easy and pain free.

I just used the latest RUU that OBJ posted in the Collection Post. This time I'll make sure to do the initial TWRP recovery in read-only... HTC noob...
I have a Shield Tablet (post battery fire exchange) and I would like to update it to the newest firmware/os... It is currently rooted, running BitO-Kernel, and stock nvidia rom. I did all the rooting and flashing on this tablet originally, but I never kept it up to date with newer updates. I heard on this forum awhile back that it's not just as simple as flashing a new rom, something about having to flash some other system stuff first or some partition or something. Basically I'm looking for a guide on how to update a Shield Tablet from rooted 5.1.1 to the newest OS version avalible. I tried sreaching the forum, but I couldn't find what I was looking for (maybe I'm not using the right search keyworks).
Agreed, that it is typically best to keep devices updated with the whole OTA update, which include firmware, modems, and whatever other partitions (not always flashed with custom ROMs). Although I'm not sure if there is much changed in those partitions between 5.1.s and 5.2.
That is the original Shield tablet (not the K1) right?
If so, I think you can just download the full OTA zip, and flash in TWRP: https://forum.xda-developers.com/showpost.php?p=72501806&postcount=35
Then root (flash Magisk or SuperSU) right away before rebooting, if you want to keep TWRP. If you don't root, the update will cause TWRP to be replaced with stock recovery.
Another option, if you made a backup of the stock ROM before installing custom ROM (I suggest always doing that) you can restore it, and should get the OTA notification. Then you should be able to just download and update that way. Again, root before rebooting, if you want to retain TWRP.
If all the above fail, you can download the recovery OS, and flash all the components using fastboot, as described in the supplied instructions:

Thanks I appreciate the help! Yes it's an original tablet (not the k1). It's currently rooted with the Bit-O kernel running over the stock Nvidia 5.1.1 os (also has twrp on it as well). I'd like to keep root. I'll have to do some more search to see if I can find the old thread where I was told it's more difficult the a simple flash, I remember it was explained fairly clearly, I just can remember exactly what that was lol.
EDIT: found the original post where I was asking about this from last year, the issue revolves around the Staging Blob which I've never worked with before and know nothing about it (usually just ROMs and kernel flashes and occasionally radio images).

You won't be able to update the OS and keep root. Which is pretty typical when updating most Android devices (root will be lost). But for the 1st and 2nd options I gave (flashing the OTA zips in TWRP), it's easy to just root the device again. Just have your preferred root zip (Magisk or SuperSU) on the phone when you update. Then after the update (before rebooting to OS) while still in TWRP, just flash the root zip. Then you will be rooted, and TWRP will not be wiped (replaced by stock recovery).
3rd option (flash Recoveyr OS in fastboot), getting root again is a few more steps, but still not that hard. After flashing all the components, reboot and verify everything is working. Then go to fastboot again, flash TWRP. Then boot into TWRP, and flash the root file (Magisk or SuperSU).
For any of the options 1-3, if you want to then flash your custom kernel again after rooting, you are free to do so. I'd probably verify the stock OS is working. Then boot to TWRP, make a backup of the stock kernel & ROM, then flash your desired kernel.

On the 3rd option (flash Recovery OS in fastboot), if you go to the link then click the desired version 5.2, it will expand, and you will see Downloads for the Windows or Linux files, and instructions below that. Click on "instructions" and you will see there are steps to extraxt various components, than flash each one individually using fastboot:
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot flash staging blob
If you do the other methods (flash OTA zip with TWRP) I believe all these components are included, and just flash automatically.

Oh ok thanks! I'll definitely try to flash that 5.2 OTA zip from twrp and see if that works. After that, I should be able to flash any current update (like 6.0) also, correct? And I assume I need to flash 5.2 first before flashing 6.0 (or whatever the most current shield tablet OTA is), correct?

Pretty sure it's how I updated to 5.2 (then rooted), and probably the easiest of the options. It's been a busy last couple months, so it's all a little blurry!

Not 100% sure. It's a full OTA zip, not an incremental update. So in those cases (full OTA) it may not need the preceding update installed. But again, I'm not sure.

Ok thanks again, I appreciate all the help! One last question I promise lol. Do I need to wipe anything in twrp before I flash an OTA zip? In the past I've been told wipes are not required for incremental updates (like 5.0 to 5.1 to 5.2) but they are usually recommended for larger os revisions like 5.0 to 6.0, does that still hold true?

I would say that is still true. Don't think you need to wipe anything (except cache and Dalvik - which I usually wipe when flashing anything), and I don't think I did either. Make a TWRP backup, in case anything goes wrong, as well as any other backups of apps, data, etc. (such as Titanium)..
Ask all the questions you like. It's fun to help, although I may not necessarily always know the answer!

On my shield tablet, I have a 128gb SDcard in it, and I use Folder Mount to move all my large apps and games to the SDcard. Do these backup through TWRP if I check every box (I don't think it does cause there isn't a check box to backup the sdcard)? Would titanium backup work better to backup and restore these large apps & games that were moved with Folder Mount?

You can't backup internal storage or SD card in TWRP.
I don't personally use anything like Folder Mount. I would think as long as the folders are where they are supposed to be, and the data for Folder Mount is preserved/migrated properly, then it will all still work as it did before the update. If you are really paranoid, you can make a copy of the folders on your SD card to your computer as a "backup".

I just noticed on that download link you posted earlier, that Nvidia lists the newest update as 5.2.0, but that is actually Android os version 7.0. Earlier when I said on was on 5.1.1 I meant Android os 5.1.1 (as in Lollipop), not shield os version 5.1 (which is Nougat). Sorry if that wasn't clear in the beginning. Does that effect any of your original advise? Just thought I should double-check that.

I'm not sure if it matters with the OTA. My feeling is, that it won't matter, and it will still install.
My guess is that in the worst case, the OTA fails, and you have to resort to flashing the recovery OS version.
