Help rolling back to the april bootloader? - Google Pixel Questions & Answers

The may security patch has kind of made this phone hell to do anything with thanks to the new android verified boot feature and i heard you can flash the april bootloader to get rid of this however my attempt to do so didnt work. If anyone has like a step by step guide on how to go about doing this it'd be much appreciated.

Update to the June factory image. It's just like April. No more signing the boot image.

Sideloading OTAs, in order or can skip?

So I was away from my computer when the January Security update came out so Im on the December update.
I would like to know can I just jump straight to the Feb update when its available or do I need to do Jan first then Feb?
im unlocked, rooted, ex kernel, google store phone. thanks.
You can just jump.
my phone is on the latest 8.1 april ota.
after the update the phone freezes when placing and recieving phone calls
is it possible to "downgrade" to the previous ota the one from march to test the phone app or will it break the phone
i googled the hell out of this but only found people flashing later releases and not previous ones
thanks

I think downgrading via OTA it's quite impossible.
You have to wipe and flash the full factory image.
damn it thats what i was afraid of.

You should've have to wipe. Just flash the full image but remove the -w from the flash all bat file. That saves data and settings. But backup to be sure.

i got the verizon varient. it seems i cant oem unlock the device.
i searched all day and cant find a technique that works so flashing the stock image is a no go apparently.
life was so much easier with my nexus 6.
damn verizon.

Time to start clearing data on the dialer related apps, or reset the phone. I am hopeful that will help you. If it was soley update related the forum would be blowing up with complaints.
Now did something go wrong with your update... I'll buy that.
i just assumed it was the april security update it started acting up around the same time. i thought maybe a crappy download
i already did a few factory resets. tried third party dialers. everything i could think of.
what really sucks is i am 3 months out of the 1 year google warranty. so i am pretty much screwed.
thanks for your help bro
i will try to sideload the latest ota.. if it is still jacked up then it is probably hardware related
what sucks is i am still paying it off and it is virtually unusable lol.. at least i can text

7.1.2 Upgrade Help

Hey guys. I think I, pretty familiar with what I need to do, but I haven't done it before. Currently I'm on the FEBRUARY security update (7.1.1) and have root. I am hoping to upgrade to 7.1.2 without losing any of my personal data and apps. I am weary to try flash fire, so could someone more experienced help me out?
I know I need to download the full OTA image and flash it and remove some -W flag, but I don't want to brick my device or lose my data, so I'll let you guys steer me. Thanks in advance, by the way!
P.S. I never fully installed TWRP.
Every time, I download the full factory image and flash via flash fire.
Everything is good, except losing twrp, but i do not mind. root still available

I have tried to stay away from flash fire because I know a couple buddies who soft-bricked by using it.

No you don't, because my way is flashing the whole 7.1.2 image, except data (reminder, remove the -w from flash-all.bat).

Alright thanks dude. Which version of 7.1.2 should I get. I know some are made for different carriers but I'm in the U.S. and have a Google Store Pixel (non-XL) and using it on Verizon prepaid. I assume that should grab N2G47E, but I just want to be sure.
The other 7.1.2 is for Dutch Telecom? I just don't want to flash the wrong one on lol.

No problem at all. Second to the last post in the same thread I linked you to before. It all still works fine on 7.1.2. Did all of this myself yesterday afternoon.
Sideload did not work, used flash-all.bat deleted out the -w. When the device booted up it automatically wiped everything anyways
Download the OTA, Flash it from TWRP, reflash twrp and reboot

Did you save the file after you edited it? Take a look at the flashall you used and see if the -w is still in there. Willing to bet it is. I've done this for every update since November. Never had a problem. The only thing I can think of that would cause your data to get wiped is that you didn't save the changes after you edited it.

yeah saved it. There was only one section that had the w- and it was right before the update image. I can try it again at some point later on but that's what I did. I tried to sideload adb the OTA first which does not wipe data but kept getting an error saying device not found and emulator.

Your instructions worked perfectly for me. I'm nor sure what setup the other guy had, but I did make sure I removed the -w like 20 times.

I'm stock rooted with elenentalX. Can I take the OTA now and just reroot and reflash after? Or do I need to unroot prior?
If I try to unroot by restoring images it says "Stock backup does not exist!"

I believe you'd fail the OTA if you have an altered boot, but you can try.

I dumped the old boot before rebooting just in case: https://drive.google.com/file/d/11MjB4kTOHuxbUyHe_kIwZ1d0wqp6-Nmf/view?usp=sharing
You can flash it to your boot slot while rooted, take the OTA, and then install magisk to the other slot before rebooting.
Drop a shell.
Determine current boot slot: getprop |grep boot.slot
Flash the boot: dd if=/path/to/boot_b.img of=/dev/block/by-name/boot_b (change to boot_a if that's your slot)
Of course, don't reboot since you'll lose root. Instead, you should now be able to take the OTA, and then use magisk to patch the other slot before rebooting.
Magisk should now have a backup for next time, so you can uninstall/ota/install in the future.
Nice...4 days in, and patched with the security update already.

Was curious cuz I was able to update the OTA on my pixel when rooted with custom kernel.
For some reason after I ran the magisk uninstaller and made sure to flash the stock boot image I still ran into problems updating via OTA and after sideloading the OTA for the Sept Update with success I found that TWRP would seem to freeze whenever it got to the main screen for some reason. I was able to use adb commands to reboot to bootloader and flash the stock kernel for the update and was able to boot normally. Just wondering if anybody else is having issues with TWRP freezing after installing the security update and yes I did remove fingerprint and lock screen security before booting into TWRP so I know its not something from that causing it to freeze.
Anyone try to Fastboot install the Sept update?
Tried 3 times and the screen was unresponsive every time after booting to setup
Finally went back to last months original P release and everything was as normal and updated from there...........
Just installed patch. Scrolling feels so much better, especially when scrolling slow.

That's exactly what happened to me.. a user on /r/essential said they had the same issue; frustrating!
I'm going to be going back to 8.1 via fastboot, and then flashing 9.0 august, THEN fastbooting september, and if that doesn't work, I'm going to fastboot 9.0 august and then try OTA to
get my screen back.
Really weird stuff.
EDIT: Here's a supposed fix for those with the touchscreen issue - https://www.reddit.com/r/essential/comments/9d0lg3/for_anyone_having_trouble_with_touchscreen_not/
I don't know if we're allowed to link to reddit or not, but I'm doing that fix now.
Thanks!
my PH-1 is no longer recognizing my T-Mobile SIM.
i bought this used & my SIM worked fine up until OTA install. i've tried a different T-Mo SIM & it produces same Invalid SIM error.
the bootloader does show Variant = Sprint. i never did check the bootloader after I purchased it a little more than a month ago.
i'm currently reinstalling August 2018 Release via fastboot & see if that helps.
EDIT:
August 2018 Release resulted in no touch response & unable to progress through setup.
giving June 2018 Release (Oreo 8.1 ) a try via fastboot.
i just want a working phone back

Are you rooted? Here are the unlocked modemst files: https://drive.google.com/file/d/1LQC-2QOC-PWX7vza-82tpwFrnUjaGZVq/view?usp=sharing
You can try to dd them:
Code:
dd if=/path/to/modemst1.img of=/dev/block/by-name/modemst1
dd if=/path/to/modemst2.img of=/dev/block/by-name/modemst2
Would be a good idea to backup your current images

There's no factory image right now so you can't use the corresponding boot image to flash magisk back, it might work with the May one but I wouldn't count on it. You can also try the A/B magisk feature (flash stock boot.img, apply OTA, install magisk to inactive slot). You will definitely lose TWRP though. This wouldn't be a problem if fastboot boot worked.. I'm sure they'll release the images soon enough.
I'm still @ feb patch lol
can never get the OTA
Can someone post the build number/build version of the update?
OPM1.171019.011-RZR-180803.6033
Android version...8.1.0
Was trying to see if I could grab the factory images...doesn't look like it.

They seem to be taking their time, last time it was within a day or so.
Out in HKG, and havent gotten the update yet

october security update Android 9 Mi A2 Lite

So I just received a new security update, I don't think there's anything more than just the latest security package
same here, just 65 MB. couldn't find any new features yet.
Scrolling is definitely smoother.
It seems like booting up takes shorter time to load unlike with the previous update patches.

Well at least i am not alone in this one, hopefully Xiaomi will fix this issue and we can update it normally. Gonna follow this thread.
Especially if you've rooted, you probably have modified system or vendor partitions.
You can see what the OTA doesn't like by looking at adb.
Code:
adb logcat | grep update_engine
There's been no 10.0.14.0 fastboot image but I do have backups of these partitions I made myself. They're huge but I might be able to get them on the internet if needed...

So, now with 10.0.16.0 released, I was able to skip the .15 version. I had to download the complete package (around 1 GB) but now I'm on latest version. Just need to root again .
