[Q] Anyone knows the difference between bootloader 4.13 and 4.18 ?

Bootloader is the last thing I would like to touch unless it is absolutely necessary. So is wondering what is the key changes that warrant to flash it.

I've been wondering the same... Also, excuse my ignorance, but bootloader is not updated when you do OTA from 4.21 to 4.22 ? It has to be update separately?

I upgraded mine using the adb sideload method, and it also changed my bootloader to 4.18. I don't know if there are any significant changes, but I think its best to upgrade to the latest bootloader as you will have the latest and greatest, and most development will stem using 4.18 anyway. So just upgrade.

I'm also wondering... by the way, dalanik, the bootloader IS updated via the OTA... it's in the UPDATER SCRIPT. (And it's how I got updated).
Code:
...
....
ui_print("Writing bootloader...");
package_extract_file("bootloader.raw", "/dev/block/platform/sdhci-tegra.3/by-name/USP");
...
..
Interestingly, in the FLASH-ALL.bat/sh script, in the FACTORY IMAGE of JDQ39, the new bootloader is flashed by the more traditional method, using fastboot...
Code:
..
...
fastboot flash bootloader bootloader-grouper-4.18.img
fastboot reboot-bootloader
...
..
----
Anyway, I've subsequently NANDROID restored back to my 4.2.1 based CyanogenMod ROM... with the updated bootloader... only issue is, when in FASTBOOT mode, the Vol UP/DOWN keys, when USB plugged in (to PC or charger, it doesn't matter), sometimes become non-responsive - meaning I can't select recovery, for example. It's a minor quirk, easily resolved by disconnecting and then reconnecting again.
What we need here, is a BOOTLOADER guru; some guy, who knows everything there is to know about BOOTLOADERS... I'm sure there is one out there, somewhere.
Rgrds,

If you update your N7 OTA, everything will be updated. You DO NOT NEED to update the bootloader. It's a whole package that is ready for installation.

But I cannot use OTA without reverting back a number of things
I would assume bootloader in android is just the equivalent of GRUB. The reason I don't want to touch it is that it is if I am not mistaken the supervisor of the device so if I get a bad flash, I would lose access to it even in fastboot.

In fact, the bootloader actually flashes it in place in both instances.
"USP" (or "staging") is kind of a garbage partition - do a dd (read dump) of yours right now and you will easily convince yourself that the bootloader ain't in there.
Whenever a hardware reset occurs, the bootloader regains control of the device. I have to presume that on every hardware reset cycle, the existing bootloader inspects the USP. Clearly it can not simply blind-flash whatever is in there; that would suggest that the the bootloader blob thrown into USP has a MIC (crypto Message Integrity Check) and the existing bootloader can perform a signing check on it.
Don't know if the same is true of a fastboot flash - but then who wants to run an experiment where they purposely flash garbage into the bootloader in order to find out?
On other (HTC) devices I had, the bootloader would inspect (bootloader version) strings stored in the misc partition, and resolutely refuse to flash factory ROM files if it got a whiff of a potential downgrade install. That was easily overcome by byte-patching the misc partition from a rooted OS, though.
[speculation]With this USP -> real_bootloader_location funny business going on, I am wondering - if the MIC key is version stepped (that is, the public key provided in the current version of the bootloader is updated with every revision, and the *next* version of the bootloader is signed with this key) then this would create a upgrade-only-lockstep sequence.[/speculation]
Has anybody ever downgraded their bootloader - either with a "recovery-flashable zip", or fastboot? Just curious.

I have downgraded my bootloader for my N7 from some version to the 3.44 then upgraded to 4.13 then upgraded to 4.18. The reason I downgraded I cannot remember.
And no I did not use a recovery flashable zip, I went into fastboot and flashed it with an img.

Flashing stock recovery to Homecare TN7

I was able to flash an EVGA ROM successfully and also Shaky156's CWM recovery. Primary reason was to get rid of Chinese notifications completely. Problem is that I cannot get the 1.1 OTA update to install because of the CWM recovery. I tried to flash stock recovery via fastboot but was not successful. Tried different versions even the BAT_CWM_recovery but it won't accept any except Shaky's version. Also tried the Super Tool but it won't recognize the tablet. I have previously installed the SDK and can get fastboot to run. Will try version 1.5 if it works.

Always erase the partition beforehand.
fastboot erase boot
then... as an example
fastboot flash boot boot.img
or
fastboot erase recovery
then... as an example
fastboot flash recovery recovery.img
Make sure you are cautious never to loose fastboot ability. Other words if your bootloader can't be obtained from restarting and hold buttons down, then make sure you don't restart till you get a successful flashing. Always have the system ADB enabled and certified with the computer.

Did what you said but still no stock recovery installed. When I reboot after erasing the old recover and flashing the stock instead of going to recovery it just boots up. Looks like the recovery never gets flashed. I did check if the tablet is being recognized by the computer before any flashing. After flashing the stock recovery it says okay so I don't know what's happening.

Yes, tablet is unlocked. Says so when I boot into the bootloader. I have flashed Shaky's CWM and it installed fine. Don't know why the tablet does not like the stock recovery. Even tried BAT-cwm recovery but also failed to install. I'll just have to wait for someone to come up with a flashable ROM if the Kitkat update comes around.

Do your best to get Bat_recovery for the recovery parititon and the 4.3.1 boot.img for the boot partition, shared on my Tegra Note Discoveries thread. Never flash the bootloader partition unless you are really know what you're doing. Then possible flash the system partition with Tom's system.img with;
fastboot erase system
fastboot flash system system.img
Tom's image should patch and is an English styled setup so you get all the Google Apps, etc.

Here's what I did:
1. Erased the system and flashed the 4.3plus system zip.
2. Erased the boot image and flashed the 4.3plus boot image.
3. Erased the recovery and flashed the bat recovery.
4. Rebooted and got stuck on the Tegra Note screen. (flashing on and off).
Tried to experiment and flashed another boot image and this time got stuck on the Tegra Note screen but this time it was not flashing on and off. Turned it off but nothing happened, Pressed the key combination to boot to the bootloader mode but failed. I thought I bricked it and then tried to go the the apx mode and was successful. This time I pressed the bootloader key combination and thankfully was successful. I thought I bricked the tablet.
Is there a way to flash the 4.2.2 ROM? Read somewhere that someone flashed the old ROM and the stock recovery. Once done he was able to update to 4.3plus. I thought there was a flashable 4.2.2 ROM at rootjunky.com but when I clicked on the link I got an error message saying that the file does not exist. I asked the poster where he got the ROM and recovery but never got a reply.
I'll try to flash the 4.3 ROM back

Don't know how to do that.

I've managed to flash a 4.2.2 ROM (tried the deodex version first) but not the stock recovery. Funny thing is that only Shaky156's version can be flashed. The big problem with the ROM is that there's no wifi and that sucks big time. It means I can't update the the firmware. Will try to flash the odex version and see the wifi works. There's no access to the files too. Good thing the bluetooth works.

The no wifi problem is endemic of a broken/mismatched boot.img to system version. Get an original (eg EVGA version) boot.img not a modified rooted version, since SuperSU sideloaded will give proper root later on top of an original boot.img.
I have boot.img shared on Tegra Note Discovery thread.

Try using rootjunkie supertool and get new kit kat or flash another ROM very easy to use

No luck. I tried what e8hfff suggested but still got no wifi. I used to have a Korean version of the Galaxy S3 and I could flash the modded ROMS made for the international version only if it is converted. Some guy came up with a converter and you flash it after you have flashed the modded ROM. We might have to get something similar if we want to flash EVGA ROMs.
Right now I'm not that concerned with getting the Kitkat update since there's something wrong with it (write to SD card). Once they have come up with an update to correct the bug then I'll give it another try. SO for now, I'll stick to the 4.3 ROM.

Yes try, TegraNote_bootimg_4p3p1rip.zip first as I haven't tested the 4.4 boot.img, and only use the boot.img within as there is another directory of the uncompress boot.

December build are up

Go to the Google site guys...build is up...looks like one to rule them all

Here is a link to the OTA https://developers.google.com/android/ota#sailfish
Or if you want the factory image
https://developers.google.com/android/images#sailfish

Interesting there aren't separate builds...

Do they post a changelog anywhere? Curious what changes are in store.

More interesting... it looks like the 6P will have a separate build for Verizon this month...

Waiting for non verizon build like the one from November

This build NMF26O seems to have a newer baseband than the Canadian update (NPF26J). Hopefully LTE issues sorted for those who have it.

I haven't finished extracting it...is the bootloader the same or has it changed?

do i need to flash every OTA or just the last one? currently on 7.1.0 (Europe, NDE63U, Nov 2016)
google is not really informative at this point

I'm getting the December OTA as I type this. I have a 32GB Pixel with locked bootloader, from the Google Store.
EDIT: Now I'm getting it on my N5x as well. I haven't seen an OTA roll out this swiftly before.

OTA just popped up... Verizon pixel 128gb

Do those of us on Verizon have to worry about thisessing up unlocked bootloader if it's already unlocked??
Also curious if this patched the bootloader exploit used

has anyone flashed the factory image or side loaded the OTA for a non-VZ device yet?

very nice, which commands did you use to flash?
I'm currently rooted with TWRP alpha2 and SuperSU SR5. I'd like to update without losing data.
My system is on Sot B so I'm thinking:
Code:
fastboot flash bootloader bootloader.img
fastboot reboot bootloader
fastboot flash radio radio.img
fastboot reboot bootloader
fastboot flash boot_a boot.img
fastboot flash boot_b boot.img
fastboot flash system_b system.img
fastboot flash vendor vendor.img
and then to get TWRP back:
fastboot boot twrp.img
- TWRP install twrp.zip
Reboot into recovery
- TWRP install supersu.zip
Does the above sound accurate?

I just sideloaded the OTA onto my VZW Pixel with unlocked bootloader. My bootloader remains unlocked and I flashed twrp and SuperSU SR5. So far everything is working fine.
According to the dePixel8 website (http://theroot.ninja/depixel8.html) "dePixel8 is patched in Android 7.1.1 and newer, do not ask for future support or any kind of support."
So if you take this OTA from the phone (on an unlocked bootloader) you may well be locked out for good (unless someone finds another exploit).

Thanks for the reply. I did some more reading and realized it's safe to install the OTA since I'm already unlocked. The update can't relock it. I already installed it via OTA and everything is ok

Stock unrooted device in soft-brick bootloop running 7.1.1

Hi,
So quick summary of what happened. I went to make coffee, came back to desk and my N6P has been stuck in boot loop.
It was running the latest Android 7.1.1 build (NPF26F)
I can access fastboot and recovery fine. However, I can't flash anything from fastboot as the device wasn't unlocked.
I tried wiping data / factory & cache from fastboot and recovery with no difference in result.
I also can't seem to sideload anything as all the OTA's from google come back with 'Can't install this package (%Date of build%) over newer build.
The latest OTA i can find is: 7.1.1 NMF26F (angler-ota-nmf26f-61b4a915.zip)
I also tried the official 7.0 NBD91K (angler-ota-nbd91k-32c2eac8.zip) with the same result.
Is there a different OTA I can use or can I force it to sideload an older version or any other suggestions?
I really don't want to have to deal with my telco. I'll be without a phone for weeks if I have to :'(

I have a phone with the same problem. Haven't gotten an answer yet. I am starting to wonder if it's an issue with the build.

You can unlock bootloader if you have fast boot. The computer needs to recognise your phone. Then just follow the steps in the beginner's guide.

You never went into Developer Options and toggled the "allow OEM Unlock"? If not, you will not be able to unlock bootloader via fastboot.
And are you positive you did a proper "factory reset" from recovery? From stock, this should get you out of a boot loop. The naming convention Google used for DP2/Public Release was screwed up and I've seen others reporting the inability to flash OTA's but the solution was to flash the full Google image. As someone else suggested, until a new OTA hits with a newer (higher) number, you may be out of luck. Maybe someone with more experience can help with perhaps altering the OTA signature?

Yup never did it :'(
Didn't think I needed to unlock / root my devices anymore since I can get all the functionality out of stock android these days. Though now I feel like I'm being punished for not unlocking it :'(
I'm positive I did a factory reset from recovery. I do believe flashing a full google image would fix the issue, but im unable to from fastboot as device is locked and sideload images appear to be older :'(

Really sorry to hear this, and I know being without the phone even for a day or two is inconvenient at best. Could be critical for your work or school. Most every bootloop I have encountered, I've been able to fix by re-flashing the kernel. Either stock or custom... like EX Kernel. Have you ever played with WugFresh's NRT? You can temp flash TWRP and maybe temp flash or flash the kernel? This probably won't work with a locked bootloader If you could just start the OS, you could toggle the OEM unlock. At a minimum, TWRP will give you a file manager, MTP file transfer, wiping and other tools. If you have time, it may be worth a try. Other than that, successfully altering the signature of the OTA may work, but I've not seen any work on this, but have never had to look. I'd keep searching for ppl having the difficulty of going from DP2 to Public Release (older/newer) and see if there was another solution other than flashing the full image, which obviously you can't do right now. Good luck, and let us know if you make any progress.
Edit : Read here for possible help. This may work in conjunction with getting TWRP installed via NRT.

Many ppl have had problems sideloading the OTA coming from DP2 to Public Release NPF26F->>NMF26F and not just the 6P. Because the Public release numerically is "older" the OTA will not flash. When unlocked, the solution was to flash the full Google image, rather than the OTA. Why in their infinite wisdom Google did this I have no idea. Options are very slim when your bootloader is locked and you are stuck in a boot loop. OP cannot flash a full image when the NMF26F OTA is parsed as being "older".

How can flashing the latest factory images released on 6 December can give this error? Make sure you download the 6 December factory images

I believe it's because the latest OTA on https://developers.google.com/android/ota is 7.1.1 (NMF26F) and my phone is already running 7.1.1 build (NPF26F).

This guy gets it!!! Yeah, I've unlocked a lot of my older devices and am comfortable with 'messing' my devices, but I didn't with the 6p as the stock experience is great now. But now I feel like I'm being punished because my device is dead with no recourse for action. Unless google release a newer full OTA.

If you haven't given up yet and gone back to the carrier with the phone, try the NRT toolkit to temp flash TWRP, and then FORMAT each partition, then try to reflash OTA with TWRP. Under "Advanced Utilities".

This will work on a locked device? I'll give it a crack and report back.

Firstly your link is broken: It's http://forum.xda-developers.com/nexus-6p/general/guide-fool-noob-proof-to-clean-installs-t3518311
Secondly as I've mentioned a few times including the OP. The device is locked. You need access to Android OS to unlock. It can not be done just from bootloader. So this does not work, but thanks for posting the suggestion anyway.

Sorry I thought it would have worked you should wait until the January security patch as all the other users said best of luck

Update — February 2019

- There are no Pixel security patches in the February 2019 Pixel Update Bulletin.
-Functional patches
All Pixel devices running Android 9 will receive an Android 9 update as part of the February OTA. This quarterly release contains many functional updates and improvements to various parts of the Android platform and
supported Pixel devices.
Now it is installing. I still don't know what is changed. The Update is 111.6MB.
https://source.android.com/security/bulletin/pixel/2019-02-01.html
Security patch levels of 2019-02-05 or later address all issues associated with the 2019-02-05 security patch level and all previous patch levels. To learn how to check a device's security patch level, read the instructions on the Pixel update schedule.

Has anyone had issues updating to FEB then applying Magisk?
Thanks

I'm having issues flashing the factory image without "-w," gives me the "Your device is corrupt and cannot be trusted" screen. Anyone else?
EDIT: flashing the Jan update fixes this and allows my device to boot again

So, I found this little egg by tapping, then pressing on device number. Is this new?

Paint.apk ?

Nope, it's been there before.
The only visual change I have noticed on my Pixel 2 XL so far is a slightly different color on the About Phone section in Settings.

It's the Easter egg:
"The new Easter Egg can be found by going to ‘System’ > ‘About phone’ > ‘Android version’ > and tapping the nine multiple times, then the old P Easter egg will appear on a Pixel 3. If you keep taping the ‘P’ a few more times, the drawing UI appears."

The about phone option is no more in the system section.

I had issues with the update in general, but it was my fault. Everything worked out in the end. I think more than a little of it was because of the changes under the hood that Google applied.

Updated perfectly. Downloaded OTA, flashed in TWRP with TWRP zip, reboot to recovery to flash kernel then magisk. No issues whatsoever.
February feels much better, although could just be a placebo ?

I flashed with Duece script at usual. I'm no longer able to fastboot flash TWRP because it just hangs at the initial TWRP screen. Then I have to flash the ota or stock boot.img for the phone to boot. The old process to root doesn't work for me on the February update. I still was able and flash a magical patched stock boot image. So now I'm rooted with no recovery to flash a custom kernel.

Fastboot boot twrp and then once booted install the twrp zip. Get away from doing things thru a tool kit.

When I fastboot TWRP it hangs at the initial screen and never starts. On January and every other update I've had no issues booting TWRP.

I'm not sure what state your device is in so I'd flash the feb factory image using the flash all batch file with the -w removed. That'll return your device to stock without wiping it. Then fastboot twrp, then install twrp, if you want it, then install magisk.

Neither of those are the issue because I was able to fastboot flash the magisk patched kernel image. I'm kinda leaning towards TWRP issue. If I go back to January update I can then fastboot flash TWRP . I'm actually shocked no one else is having this issue.

Not sure if I'd consider Deuces flash script a toolkit per se...

It's a toolkit. Toolkits generally simplify processes and hide output that advanced users can use to achieve the same results without the toolkit.
