[Q] How to update bootloader?

I cannot seem to be able to update my bootloader to flash new nightlys for Vanir. I have extracted the radio and bootloader from the factory image, but I cannot flash them. I keep getting an access denied from adb, while I'm in fastboot.

you cannot use adb in fastboot. You can only use fastboot in fastboot. adb only works in recovery or android

Correct me if wrong but what you want to update is your recovery.

So I managed to flash the bootloader and radio, but I still cannot flash any CM based ROM. I keep getting a Status 7 error.

Updating Nexus 5

Hello,
I have a Nexus 5 with root, stock rom, Franco Kernel and the custom recovery is TWRP. I accomplished this by following a guide around this forum, I know very little about Android. The Android version i'm running is the 4.4.2 and the phone keeps asking me to update do the newer version, however, when I try to do it, it takes me to the TWRP menu, and when I try to install it there, I get this error:
"/system/bin/thermal-engine-hh" has unexpected contents
E: Error executing updater binary in zip
Error flashing zip
How can I update the phone to the newer version of android? Can anyone help me? Thanks.

Start here, then still questions in that thread

First thing, turn off mobile data. Your phone may try re-download it over and over again and use up your mobile data plan.
To install the ota via the ota update on the stock rom you will need to return to stock recovery and maybe stock kernel (not sure about this one).
NOTE: Before trying the below steps as I haven't tested them myself, please backup your ROM first. Better safe than sorry.
You can try installing the OTA updates manually from TWRP. You can find the links in the post - http://forum.xda-developers.com/google-nexus-5/general/ref-nexus-5-stock-ota-urls-t2475327.
If you are running 4.4.2 KRT16M you will need to download three updates.
1. KTU84M from KOT49H (4.4.2 update to 4.4.3)
2.KTU84P from KTU84M (4.4.3 update to 4.4.4)
Download them together and also put on a flashable zip of TWRP in the same location as it looks like it will reinstall the stock recovery.
You can even put on one of Franco kernel just in case too.
In TWRP select install zip and install number 1 first, then install 2. and finally install TWRP again. You should be updated to 4.4.4.
You can then install Franco kernel again just in case.
I hope this makes it easier.
EDIT: follow the link in the previous post as it has different scenarios and the steps needed.

Just download the full rooted stock ROM in android development and flash it without wipe from recovery.
It's actually fewer steps anyway.
OTA = revert system changes and/or kernel, reboot into recovery, flash the OTA , boot to bootloader, connect to pc, fastboot flash recovery, reboot into recovery, flash supersu.
Rooted stock = reboot into recovery, flash the ROM.
No brainer really. Flashing an OTA if rooted is a fool's errand.

[Q] ota sideloading aborted

Hey group mates please help me
I'm currently using a nexus 5 and thought of sideloading the ota zip through nexus root toolkit so i first flashed stock recovery and then when i tried to sideload it, it started flashing till it reached 61% and which my phone said installation aborted for no reason.. Tried this more than 3-4 times but the result were all the same
I'm not sure what seems to be the issue here so it would be great if any one could help me solve this issue
Thanks in advance

I have the exact same problem. The sideload gets to 61%, then shows the following message:

I have a stock recovery, was rooted using Chainfire's first method for Lollipop (patched kernel) but flashed the stock kernel (fastboot flash boot boot.img) from the N5 5.0 image before the sideload.

You can't be rooted to use the OTA. Anything that is modified in the system will cause this.

I downloaded the full image and extracted just the radio, system and boot image files. Then just a few fastboot commands with bootloader reboots inbetween and 5.0.1 works.
For reference, I used the following:
fastboot flash radio radio.img
fastboot reboot-bootloader
fastboot flash system system.img
fastboot reboot-bootloader
fastboot flash boot boot.img

So while sideloading it should I unroot as well?

So to sideload I have to be in complete stock without even SuperSU.. Is that correct?

I was thinking about doing this, too... but am I correct to assume that this would cause data loss? I have TWRP and SuperSU installed at the moment.
Or, if there's an easy way to ditch these and do the OTA, I'd be okay with that, too.

It won't cause any data loss. It's about the only way to get the ota to work. But in your case, since you have twrp you should also flash the stock recovery.img
Sent from my Nexus 5 using XDA Free mobile app

No data loss (well, apart from root) if you flash just the radio, system and boot images. Worked great for me.

Thanks for the tips, guys. After extracting the full 5.0.1 firmware from the Factory Images page, there are system and boot .img files, but no radio. Is this normal?

There's a radio. It's in the first file you extracted, not the zip you also had to extract

Good thing I didn't get past this step -- I had downloaded the wrong factory image. D: That'll explain things a bit...
---------- Post added at 02:13 PM ---------- Previous post was at 01:54 PM ----------
Alrighty! New problem: After the phone boots, I get the battery and signal icons in the top right, but a black screen otherwise. If I hit the power button to put it in sleep mode and then hit the power button again, I get a quick flash of the "Welcome to Android, select your language" screen. Any pro-tips?
If I have to set up from scratch, it's no big deal. Most of the important stuff should be backed up; it'd just be annoying. All that Desert Golfing progress!!!
Finally managed to get around it. Ended up updating TWRP and re-flashing most of the .imgs a bunch, then using TWRP to first let me back up data to my computer and then wipe partitions. I'm on 5.0.1 again.
Welp, that was painful, haha. I'm sure I did something wrong leading into this, but I'm not sure what that was...

If i just flash the whole Firmware that i downloaded from Google, will i be able to flash it and loose root?
I am OK with loosing root and beeing back to stock.
At this moment i have Lolipop 5.0 that is rooted with Chainfire.

I was running rooted stock 5.0 with TWRP and had already flashed the 5.0.1 radio, so I just fastboot flashed the 5.0.1 system.img and rerooted. All is well so far.

So if I unroot and then sideload it will I loose all my data ?
P.s I'll be rooting it back immediately after I get 5.1
So is there any way which can avoid a data loss?

I still have a doubt, I saw rootjunky's video in which he sideload 5.1 to his nexus 7 using nrt..
Even I followed the same method but it didn't succeed for me

So after flashing your stock kernal and stock recovery did the sideload work.. I mean that it didn't get stuck at the 61% mark?

[5.0] Nexus 5 Refuses To Flash OTA or Different ROM's

Hello,
So I just discovered this while trying to flash the 5.0.1 OTA from 5.0. I'm rooted on LRX21O via the Nexus Root Toolkit 1.9.9 (which is what I've always used in the past with no issues).
1 Tried flashing the OTA via Google notification push. It reboot, and no changes occur.
2 Fine - I try to use the Root Toolkit again. Boots into bootloader, appears to flash the radio and other necessary components. Reboots - no changes occur.
3 I then tried to just download the 5.0.1 package and flash everything manually via adb. Everything appears to go smoothly, and upon bootup Android updates all of its apps - still nothing. I appear to be completely stuck on LRX21O without any way to reflash stock or OTA's.
Anyone have any clue why this is occurring or have heard of such an issue before?
Thanks all.

Just flash factory images. With fastboot/flash-all script.

You flash these in fastboot not adb
Sent from my Nexus 5 using Tapatalk

Did you not understand? I did flash in boot loader USING adb on my computer. All that bat script does is just automate the flashing of each image for you (system, radio, etc) so this is not helpful. I know how to flash, but flashing seems to have no effect despite successfully flashing via manually installing or just using the script

You use fastboot in bootloader, not adb.

I'm not the one asking for help. Anyways, carry on.

Your device's /system partition is tampered (you say you rooted it) and thus the OTA fails. Flash the 5.0 factory image (LRX21O) WITHOUT rooting/flashing kernels/whatever and then use the OTA zip to do adb sideload in the stock recovery to update to 5.0.1 LRX22C.

Manually use fastboot commands to flash system.img and boot.img of the full 5.0.1 factory image (not script). post the output please

I'm not the one asking for help. Anyways, carry on.

Sorry about that - didn't mean to come across snippy
It worked this time with fastboot. For future reference can this be done the same way with the OTA update zip instead of reflashing the entire image?

Would you mind explaining this? I've used sideload in cwm and twrp before but I'm unsure of how to operate anything within stock recovery. adb won't even connect while in recovery. I would like to just remain on unrooted stock until xposed eventually get's developed for ART and flash zips that way.

Sideloading in the stock recovery works much the same as in a custom recovery. Boot into the stock recovery and there is an option to sideload. Then on your pc in a command window you type adb sideload update.zip. or whatever the file name is that you're trying to sideload. Obviously, if you can't get adb to recognize your device that's a problem. But that's a separate driver issue.

How can this be possible though without a custom recovery with the sideload feature? Stock recovery is essentially unusable as it just displays a picture of a dead android on a black screen.
Perhaps we're on different pages, or am I just confused still?

sideloading an OTA update from stock recovery
Hello, to make it work you will need to use the Google USB drivers you downloaded when you go into stock recovery then press the power button and volume up once then you will see a menu option with the "install update from adb option select this and plug in your phone to the computer. After this is done you will need to go to device manager and install the USB drivers from the Google USB drivers you downloaded. at this point after that is done you then go into the folder that has ADB installed and use adb sideload filename.zip
at this point your phone will accept the ota update package and you wont lose any data, I hope this helps..

When you get the dead android you need to press vol up and then press and release power. That'll get you into the stock recovery. It's stupid and I don't know why they made it that way

Well you can't. The limitation of the stock recovery is you can only flash files signed by Google. That's why you need a custom recovery to flash most files

If you're trying to flash the update.zip to 5.0.1 you need to do that in the stock recovery. It will not work in twrp or cwm. I'm not sure what you're trying to do right now
Sent from my Nexus 9 using XDA Free mobile app

my apologies.
so originally i wanted to just flash the OTA. ended up performing a fresh install and un-rooted. but there's a few unsigned zips i like to have installed.
So I think I'm going to re-root, flash twrp, install my zips, and leave it at that. i'll just flash stock recovery whenever I need the OTA which should be quick now that I know what to do.
hope that sounds correct. thanks for all the help!

How to OTA upgrade to NOF26V?

a little background information
current build: NMF260
recovery: TWRP RC1
kernel: elemental x 1.03
rooted: yes
Mods: weta audio 9.1
So I have completely forgotten how to do a manual sideload for an OTA. Could someone give me step by step, hand holding instructions?
What I have downloaded onto PC
sailfish-ota-nof26v -4bbb310d.zip
twrp-3.0.2-0-RC1-fastboot-sailfish.img
boot.img from nof26v build (that is for recovery right?)
and i have twrp zips for supersu, elemental x, and twrp rc1
basically i forgot how to flash stock recovery, because I need to to manually update OTA right? also do I need to remove the weta audio 9.1 mod first before doing the OTA? or can i just flash over it? anyone know?
Thanks!

https://developers.google.com/android/images <---- Click Full OTA update and follow instructions. Will not wipe anything. You do need to be on official.
If you want to just flash the peices download all of them and boot into bootloader then use fastboot commands per each item. Google the commands for bootloader, radio and the kind. Very easy.

that is not in the ota.zip file and neither in the full factory image zip file

I'm not rooted but since no one answered as of yet then I do believe stock recovery is now in the boot.img file. Search the Pixel XL forums too.

Stock recovery is in the OTA under boot.
