I have a several months old s10e, which turned to have no updates (Android 10, UI 2.0, security patch level March 2020(!) although was bought around April 2021). Not even an available "check for updates" button, anywhere. This is some real downer here, with Samsung semi-Android OS. I'm dealing with this issue for several weeks now, when I expected to simply update my device via OTAs.
Also verified with local Samsung service, according to IMEI, should be Android 11.
Anyway, as I found here,
S10e not receiving updates
Hi all, I'm a long time Samsung user (started with an S2, then S4, S7 and now S10e) though this is my first post here. I'm in the UK. A couple of years ago, I bought a Samsung Galaxy S10e from an ebay seller. It all worked fine and the whole family ended up getting S10e's to replace their aging...
eu.community.samsung.com
I've downloaded the correct firmware from Sammobile:

and followed the instructions: https://www.sammobile.com/wp-content/themes/sammobile-6/assets/static/instructions-fw-5file.pdf
During flash on Odin3 v3.14, process get stuck at "recovery.img" while on device's screen, "Secure fail check : (Bootloader)" is writen on red;
with no process bar shown on phone's screen. Next four lines happen when I exit "Download Mode". Tried different USB port, different cable, one prior firmware version (July 2021 release instead of Sep 2021) etc. Many times, same results.
BTW, "Download Mode" model (product name) and "about phone" model number are different: SM-G970N on "Download Mode" upper left corner of the screen (see image above), SM-G970F on "about phone" model number. Could it be that I've downloaded the wrong firmware (one shown under "about" menu)?
Checked "Phone info plus" app, I see that phone model (G970F, Israel) is different than CSC product code (G970N, Vietnam).
I've sent the device to a lab (warranty service). It was returned after over a week, with the exact same status + factory reset. I'm furious.
Do I have a 970F or 970N device?! Which exact firmware should I download\upload?
Any ideas?
Thanks in advance

Thanks for the super-fast reply!
Can you please tell me which one should I look for on SamMobile.com, i.e. which country should I look for?
And - would it be a problem, trying to install N firmware while the device is (for some reason) defined as an F under device model (about menu)? Why is there such a discrepancy?

1. Doesn't matter which country you choose
2. No, it won't be a problem. There's a discrepancy because the device was rooted and modified to look like an F model

Thanks again, I'll try and hope for the best..
About 2, if the device was rooted to look like an F model, will it change anything else (for an example - carrier related issues due to not looking like F anymore)? Is there a potential risk with "changing it back to N"? Why was it reasonable to modify it to look like an F at the first place?

You always take a risk, every time that you purchase a used device. You can't inherently damage the device by re-flashing the official stock firmware. But a used device is never guaranteed to work the way you want it to, and it carries no warranty. So you'll just have to do the flash and then try it and see what happens
I have no idea why it was reasonable. You would have to ask the person that you got it from

Actually, it is not a used device, at least for the best of my knowledge.. I've bought it as a new device, although not from the local official importer. You say that this rooting and model modification means that the device is used?

Samsung (nor any other manufacturer) does not sell rooted and modified devices. So yes, of course it is used. The S10e is more than 2 years old anyways, so it would be almost impossible to find one that is still brand new sealed in the box

hi
gotta jump on this thread too,
I have the exact same issue, bought the phone brand new from an online store in Israel and can't get updates, can't use the Samsung camera app(had to use a different app for it) and recently the mic stops working suddenly and comes back only if I enter safe mode. If i flash the phone with the n fimware will it work normally?

If your Baseband Version starts with G970N, then yes, probably
Hi
Thanks for the quick reply
I have flashed(with odin 3.14) the latest firmware according to the baseband version(g970n) and now the same problem persists with a warning message in Korean every time I turn on the phone and also skmobile animation. At least now the phone is capable of updating and is up to date with android 11 and one UI 3.5, and also, the about phone shows the correct model. Any idea how to fix the initial problem? (mic stops working, camera fail on Samsung stock app)
It’s funny how the warranty just expired a few days ago

Thanks for your help
just change the date to 2018 or 2019 with november 1
It's been a while even since the last message. I have to inform anyone who wishes to update their firmware to Android 12. You may prefer living with your Pie firmware because the Camera started to add some foggy effect on the captured images for no reason on my device after one of the updates -very likely after an April update at the time. I know because I'm not the only one with this. There are many complaints on this on the Samsung website and no one seems to care.
As far as I can guess, it is related to some effect added to the capured images during or after shooting. It resembles the photoshop effect Convert to HDR, creating some bright areas around edges while the remaining remaining image is foggy. How stupid of Samsung.
May be they just want you to replace a 4 year old phone, asuming you'll again buy a Samsung, even with the imposed circumstances.
Been a Samsung user for years but I'm looking for some other brand for my next phone due to this kind of Factory-Forced replacing necessities. Either your phone gets laggy in a year or two, or your battery inevitably dies and you can not find a single replacement one, roughly on a par with the original. I've tried dozens of different brands including the official service replaced battery. Your phone no longer runs as long as the first day you bought it and you eventually replace your phone.
Still having this crap device in my posession, I wonder if I can revert back to Android 9 Rom from Android 12? Or any ideas on this camera issue? (It happens on any other camera)

1. No device will accept any custom firmware without being bootloader unlocked. You never specified which device you have, so I don't know if it can be bootloader unlocked or not
2. Even if it can be bootloader unlocked, I highly doubt that an Android 9 custom ROM will boot on it, since its underlying firmware would be either Android 12 or Android 11

I've seen many threads about this issue originating because the apparent H900 model for some people turned out to be a vs990 somehow converted to look like this, and everyone had the exact same issues as me, namely
1. LG VPN has stopped working error
2. Fingerprint/security tab causes settings to crash
3. Attempting to uninstall apps causes instant soft reboot
Some folks mentioned fixing their phones by finding the actual model of their phone and flashing the correct firmware. But AFAIK, no flashing software allows flashing of a different model. And none of them was clear about the actual steps they did to fix it.
Since I'm on Marshmallow, I cannot root, and I cannot rollback to the firmware I had in my phone.
Can anyone please share how they fixed their phone or someone expert in the matter?
Warranty/Motherboard replacement are out of question for me.
Any help is appreciated.
I've got the same problem, and LGUP doesn't let me flash the firmware :/
The same problem exactly
i have the same 3 stupid problems and i really very upset, i tried all solutions on internet, nothing useful
the only working software to flash is LGUP and it doesnt let me flash lower versions, its blocked from everywhere
even you cant go to security to enable install from unknown sources to install Kingroot and root the phone to find away
and no one has real answers, we need answers please help us, alot of people are lying and saying your real model is vs990 and h901bk but LGUP is refusing everything in th world, it just insist to keep you very upset
ahhh i faced same issue unfortunately , if any one expert to change the name of vs990
Same problem here. Things were kinda fine on android 5. I was dissatisfied with the battery life and chose to "upgrade"(not) it. big mistake.
- fingerprint scanner crash, com.android.settings stopped, LG VPN stopped working and restart on uninstalling some apps.
I really hope there will be some kind of miracle and we can get a fix to this. The phone itself is very pleasing, just not with all these bull**** problems.. *venting nonstop*
i have same problem here did anyone try to flash vs990 kdz ?
Thanks

AT&T Problem
AT&T only sending updates to at&T active customers who living in US and has mobile connected to at&t towers. Even TMobile user cannot get updates for at&T mobiles.
So kindly don't buy at&t and Verizon carrier mobile even unlock. Anyway there is Salutation for uninstall apps and install APK.
Use ADB for uninstalling any 3rd party application and also use ADB for installing APK and open unknown Sources.
Google it and u will find easy Salutation regarding these 2 problem.
LG using Same Motherboard VS990 for Verizon & AT&T but there is very small number on board behind Main Camera cut area. So only u can identify from here if u have knowledge about mobiles Motherboards.

Hello,
I have the same problem, At&t software, verizon board but F600L body. I've try to flash vs990 dz with LGup on it after edit the dz with hex editor. The flashing was until 80% and then showing an error window. The phone is bricked since then, not even Qfil is able to flash it.
I'm interested on the very small number behind main camera, I see there're some numbers there. Would you please share a bit more about it? Thank you

Maybe it will change something if we get the H90022b .. i'm little skeptical though. Because our issues with H900 MM started because we Flashed a H900 ROM over a H901 or VS990 board. the way i see it, even if AT&T releases Nougat, we still gonna have issues, even worse.. we kinda screwed..
i've been thinking, maybe the H90021w was somehow corrupted or missing some files...
Also, i've been reading some threads, people talking about reflashing the correct ROM, either a H901 or VS990 ... but i'm not ready to dry that considering none has done that succesfully..
For me, the solution would be find a solution to go back to Lolipop... at least it no issues. outdated maybe, but everuthing was working fine on my phone.

Looks like it needs the FRP reset method done. This is my first post on the S8 forum, and starting research on the S8, as I have one arriving next week
I just did an FRP reset on an S7 Edge. It took me several days, all day long, to finally find the method which worked on my phone. There are a lot of videos and posts with various methods... egads.
Once that method was processed, it took about 30 minutes to finally have the FRP gone and the soft reset finalize it.
If the seller on eBay did not advertise it as being Google account locked, you may want to consider a refund. Given the hardware is all ok (?), you might/should be able to un'FRP it. As I just looked at a few google search results, seems similar to the S7 method. I wonder why the seller did not un-F(a)RP it?
Do a Google search for 'S8 FRP Bypass'.
Can I just re flash stock firmware and then custom Rom?

Good question. I asked that as well and never got an answer... frustrating, so I am not sure.
My thinking leads to 'why not', as a full re-flash I'd think also writes over the Persistence directory/file, however, if it were that simple I'd a thought I would have come across a post, how-to or video, or post reply to my questions, stating yes, it can be solved in that manner.
So my post research and experimentation experience thinks once the FRP is tripped, the system prevents a simple flashing over of the Persistence partition/file with stock.

How?
Ok so I got this phone frp unlocked remotely, but the imei number on the phone back and box is the same but the phone itself *#06# comes up as dual SIM G955FD...
The phone finds the sim but still says no service I have flashed multiple csc files but still no luck so what's the issue I spent so much time and money in this poop fone
Is it 'supposed' to be a dual SIM phone by OEM model?
If so does it have the original stock firmware on it, or if not what has it been changed to.. ?
My S8+ suddenly stopped working because it says "FRP Locked". So the phone won't even boot.
Any advice?

Mad Scientist, so when you (re)install the factory binary, it overwrites the Pervasive, or what ever it is called, partition as well, which holds the FRP breach/info?
I did not think that worked, as it was too obvious and too easy a fix.
Please clarify.

Interesting. I would have though there was a software/OS method, but then I thought that Samsung would have made entrance into the Persistence partition like a vault door.
So am I understanding you all, an Exynos phone can be flashed with a combination file(?), and afterwards the OEM ROM, and that deletes the FRP file/Persistence partition? What slot would the combo file be used with in Odin?
I learn something new every day.
The problem is, I forget at least two things I've learned, every day
Thanks.

Yes. You need to flash it as AP and flash Home Csc from your FW. Then you must go to setting and apply usb debugging. Then flash your Fw and you can to log in with other google account.

Or, if you're like me, you buy broken phones. Phones with shattered screens and non-responsive LCDs, that the previous owners sell trying to recoup some of their money rather than pay to repair it themselves. Often when I replace the screen, I'm faced with FRP lock.
One time, I sold a phone I purchased brand new and owned legally. Sold it on Swappa to a guy in Florida (I'm in Oklahoma). What did my stupid ass do? I forgot to remove my account before resetting it, thus tripping the FRP.
So you CAN actually legally buy a legitimate, not stolen phone, and have FRP on it.

Instructions
A. Prepare boot image
1. Download magisk manager apk
2. Download the exact firmware (including upgrade date) for your device from https://samfrew.com or https://www.samfirmware.net/ or https://www.full-repair-firmware.com/search?q=A20 or
https://samfw.com/
3. Use zarchiver to copy AP_20xxxxxxxx.md5 to download directory. It will extract it from the zip.
4. Rename AP_20xxxxxxxx.md5 to AP_20xxxxxxx.tar and extract using zarchiver
5. Copy boot.img.Iz4 to download directory and extract (resulting in boot.img)
6. Use magisk manager to patch boot.img (use top install) result magisk_patched.img
(If using Magisk (Canary) patch, options should be remove dm-verity and not via recovery, but allowing Persist Encrypt.)
7. Rename magisk_patched.img to boot.img
9. Use zarchiver to compress boot.img to boot.tar. If you have a A205xx June firmware (U2 bootloader), you can use my one of you're willing to take a risk. View attachment boot.zip. Just unzip it first.
9a. For a20e users, try this boot.img https://forum.xda-developers.com/showpost.php?p=81649257&postcount=260
10. Copy boot.tar to Windows pc or Windows Virtualbox.
11. On phone developer options in settings unlock OEM and enable usb debugging
(If using Linux
9. Don't compress `boot.img`
10. install heimdall flash with `sudo apt install heimdall-flash`, if you want front-end install it with `sudo apt install heimdall-flash-frontend`)
B. Unlock bootloader

12. Backup data. It will be wiped.
13. Turn phone off
14. Hold vol- and vol+ and plug in power cable attached to pc then release vol up to enter unlock screen.
15. Follow the instructions to unlock
(You might need to long press vol up to unlock bootloader)
vol + to select yes to confirm.
17. Press power key to unlock bootloader.
18. Reboot and reactivate developer options and enable usb debugging. Don't enter too much data at this stage as you will lose it again later.
C. Flash boot image.
19. Turn phone on in bootloader (download) mode (Hold power and vol+ to enter recovery mode then select bootloader download mode)
20. Connect phone to computer.
21. Use Odin in Windows to add boot.tar to phone. (Select AP). Some people recommend adding the other firmware parts to their slots at the same time.
22. Restart phone
23. select bootloader
24. Select factory reset (this will wipe data)
25. Restart phone
26. install data
26. install magisk manager

If you get a DTBO error after updating Magisk, flash this vbmeta https://drive.google.com/file/d/1-dogButfxKGlx_x2tSROOBDiq90SDlmc/view
(If using Linux
To flash:
20. Detect device with `heimdall detect`
21. Flash the `boot.img` with `heimdall flash --BOOT {location of the boot.img, you can also just drop the file into terminal and terminal should auto-fill it}` ex: `heimdall flash --BOOT '/home/utku/Programlar/ext/boot.img'`
P.S: an easy way to boot into download mode is `adb reboot bootloader`)

Yeah tried that option. Samsung has our model on a bootloader 2, means our device won't accept flashing from any other firmware but the original non-modded firmware only.
Tried prince Odin,patched Odin all versions, tried Heimdall etc..
Error is ...boot secure check failed..
I've tried to flash firmware a205G only with fail error Everytime.
Psa I've had my a205u for 10 days no OEM unlock option.
Main reason why I'm not buying another Samsung phone.
Bought a Moto g7 and the g7 power ..I rooted both within 10 min from purchase. Motorola emailed me my bootloader unlock code . Fastboot flashed and Bam good to go. I'm done .

I swapped mine out for the G7 Power and already done rooted, flashed, and wrote a guide while all the 205u users are waiting for the mythical OEM Unlock to magically appear which it ain't gonna. Sammy can kiss my techie ass...we are officially divorced. I won't even go back and buy an old Sammy like I wanted to (was thinking about getting that S7 edge). It's me and Moto for now.

Maybe Samsung has an issue with US tariffs.
Samsung have certainly turned an essentially good piece of hardware into a pile of rubbish with mega-invasive bloatware. I have barely started to strip back the garbage and the phone is springing to life. Need a working TWRP before getting too keen as the path back to functionality is long and arduous without a way of restoring partitions if anything gets screwed up. Here is what the phone looks like with Google Play junk removed plus a bit of Samsung bloat removed - not everyone is ready to kick the Alphabet addiction I know, but it has become an absolute monster that eats battery and cpu cycles....apart from the privacy invasion side of it
I am finding that many unknown, non-visible apps with innocent sounding names or "security" inferred in the name are likely to be ad server or data mining software - I got wise to this with my first and last Xiaomi device

The US doesn't have an issue with South Korea on tariffs, despite Trump's big mouth.
The problem is that Sammy wants to be essentially Apple Android. And that is what's driving this crap in the same of "security". Knox has been like the devil and even sentient since it came to power almost like Skynet. And all of this started when Verizon offered Sammy big bucks to lock it down ala Kyocera with the S5 era - which coincidentially is the last great breath of air they had to give.
They don't care about the developer models either - look in the forums, many of them are just as locked down.
Sammy knows ain't that many phone companies left in the US; Tmobile done bought out half the cell companies and AT&T got the other half in a duopoly, meaning they and other companies can continue this path of nanny phones on the general public that are going for more personalized computers they can't control than actual phones that work. Most Americans aren't going to turn to GooPhone nor will many XDA devs develop any type of TWRP or rom for those types. And that means they can dangle a bells and whistle carrot while their demographic signs their privacy away.
I ain't a fan of Lenovo-Moto, but at least they let half the phone companies unlock the variant to their devices. Sammy, on the other hand, does not and is playing Xiaomi type of games on that bootloader.

It aint strange, its common. Before it was locked exclusively to Verizon; after the S3 it became more and more carriers. Then the dev models started being locked up but "open".

hi forum,
i open a new discussion with the hope that someone (more expert than me) with a bit of patience can try to understand the situation of my 5 II (model XQAS52).
Since i've purchased this device, a couple of months ago, i' ve noticed different bugs in the daily use... Various bugs reported in another thread here on XDA. A bit annoying, if you ask me.
The firmware version is 58.1.A.3.87 and i think that OTA updates are... off.
It is possible? There is a way to understand if i'm right or not?
In case, and i don't know why, my device will not receive any kind of updates, what can i do to solve this?
I've tried to repair it with Xperia Companion but every time my device shutdown during the process, and of course it doesn't complete the repair.
My build # is 58.1.A.5.330. I would probably ask Sony why I wasn't getting updates? I might go to Sony Xperia Support and try manually downloading updates.

manual updates in the app are useless: the app indicates me that the system is already updated. Same for Xperia Companion on pc.
I've spent 700euro for this device (new, of course) only to find it in this situation... it's shameful.

All variants of XQ-AS52 are currently having 58.1.A.5.395 build: https://xpericheck.com/XQ-AS52
If you have bought it via official channel you can definitely raise this concern with Sony support.
You can alternately check Software Info from Service Menu to check the exact region of your device. I can't think of why but I vaguely remember that if you device is cross flashed or not in the region it initially supported then you sometime don't get OTA updates(I may be wrong too). But first step is to check with Sony support as Patrickt mentioned.

in fact, if i launch Xperifirm, my model on the left pane has that firmware .395 (Customized EEA).
I've bought the phone via Amazon.it (i'm from Italy), but the store is situated in London.

Anyway, me too think OTA services are deactivated, at this point.

Hmm, looks like it. Create a support topic on Sony mobile forum or chat with support(if available in your region) to check if this device is official under warranty and then follow-up with them to solve the issue.
There can be alternate solution if your device is not officially supported by Sony(use Xperifirm or something like that) but first check if it's under warranty.

the truth is... i only want my device works properly. I really like Xperia devices (SP, M5, X, XZ, XZ2 and now this), and i'm really disappointed this time, sorry.
I'm seriously thinking to flashing it with and old firmware with Android 10. Maybe i'm wrong? I don't care, later with future updates, i can always flash it again with updated firmware (hoping for the best). My personal problem is that i'm totally noob in this kind of things, i don't wank risk to ruins my phone.
So, if someone with a bit of patience can help me to flashing and old firmware (i have it already: Android 10 Customized EEA) would do make me a favor. It doesn't matter if my OTA Services would continue to stay deactivated. But, at least, my Xperia should be works great with A10.
i contacted SONY with email, but is not very helpful to me. They say, of course, to send the phone to the original Store in London, or to send it in Verona city (here in Italy) for assistance and repair.
The problem is i have no other spare phone to use, at the moment when my XPeria 5 II will be in Assistency.
Xperifirm show me the different firmwares available for my model (XQ-AS52).
I suppose to download the first, perhaps (?) and flash it.
Every updated firmware there in the list have italian language?
I would try first factory reset. power button and volume down and factory reset. If that doesnt work you can try and flash the newest europe firmware for your 52 model

hi Cptmfruitloops and thanks for your reply.
I will try your suggestion: if i push power button+volume down will appear to me some sort of... recovery with various options, i understand right?
yeah power down and then hold power button and volume down until it vibrates then let go and you will be greeted with recovery and from there you can factory reset your phone. Before you do though log out of google on the phone and remove the device from your account (not required but recomended)

Done, but for now with the smartphone connected on Wifi, no system-updates yet.
No Google account logged in, nothing of nothing, no sim-card inside (i use my number and my account on another phone at the moment), but i don't think all of that is a problem.
I will wait a few hours, 1/2 days perhaps, if the updates don't arrive, i will try again a software-repair with Xperia Companion.
Thanks Cptnfruitloops. If you have other suggetions, i'm all ears.

yeah, i've used Newflasher (by munjeni) and everything's ok. The problem is that OTA are always blocked. I think this is the situation, basing myself on other users experiences in the Newflasher official thread.
Every new firmware i should flash it manually with Newflasher. This is... a little annoying of course, so i think to flash my phone again in the future, maybe 1 year, when Android 12 is available and perhaps with future updates firmwares, more stable.
Hi I'm in the same situation, I buy my xperia 5 ii on Amazon.de from Italy and it doesn't update. I will make the return.

hi xire68, i'm sorry to read this. From what i've read on the past months, many users here and on the web, are encounters our problem, the same problem: no OTA updates on their devices.
I don't know yet why this happens: the only way to update our smartphones is to use Newflasher (by munjeni), download the firmware you want and flash it. The method is very very simple, but i understand this is not a good way to updates our phones. We've paid for this Xperia, in my case 699euro and i expect updates like should be. And not to solve the problem with alternative methods.
Anyway, i understand your move.
I've been doing at least 2 years of research trying to figure out even the slightest possibility of rooting Qualcomm chipsets, and I think I might've found it. Does anyone here think it's possible to use QPST and EDL to flash a modified stock rom with SuperSU in the system directory to root a locked bootloader?

Not necessarily. I can guarantee it's possible to root it because you can in fact load ROMs without unlocking the bootloader. I'm just curious if you can force the rooted rom into the system without the bootloader rejecting it.
Yeah, sure... if you can crack the EDL protocol instead.
AFAIK (at least on OnePlus) it lets you write to all flash partitions, and I'd assume that also means the ones that hold the crypto signatures used in trusted boot. You certainly could modify certain partitions, sign everything again, and create an image if you knew the format. Not listed in AOSP, though, like building your normal custom ROM.
Disclaimer: I've only ever gotten a custom OS with locked bootloader on Pixel, though (Calyx OS, modified with a few OS code changes and the Magisk stack) but I don't think that's a QC phone to have EDL in the first place.
Now Samsungs are notorious for the e-fuses and whatnot, so it may be they have some asinine defense against it... I stopped dealing with vendors that don't outright support custom ROMs (basically down to OnePlus, Google, and Asus if you can afford one). My life has been much easier for that.
Now of those, Verizon usually has a custom firmware to support their bands, which DOESN'T let you unlock bootloader. Some people have reported on some (OnePlus) phones flashing the international rom via EDL lets you overwrite that... but not sure if it loses the 5G mmWave and sub6 bands or whatever VZW uses that the rest of the world does not have.
Hope that helps...?

A locked bootloader means that it will refuse to load unsigned code. It's checking for system integrity and rooting/loading a custom ROM will always trip this check unless the custom ROM has the proper signature and I highly doubt it does.
Verizon phones are known for being locked down. There is nothing you can do.

I am definitely aware of that, but if you aren't flashing a *custom* rom and are just using a stock rom with added files, does that still change the integrity?

Now Samsungs are notorious for the e-fuses and whatnot, so it may be they have some asinine defense against it... I stopped dealing with vendors that don't outright support custom ROMs (basically down to OnePlus, Google, and Asus if you can afford one). My life has been much easier for that.
Now of those, Verizon usually has a custom firmware to support their bands, which DOESN'T let you unlock bootloader. Some people have reported on some (OnePlus) phones flashing the international rom via EDL lets you overwrite that... but not sure if it loses the 5G mmWave and sub6 bands or whatever VZW uses that the rest of the world does not have.
Hope that helps...?

Thanks for that. I honestly don't mind losing 5G, it's constantly an unstable connection anyways. I've been considering just buying a Pixel from overseas, but I've been chipping away at this for too long and am probably gonna keep trying.
I'd be ok with manually resigning everything if it meant rootable for QC Verizon chipsets.

I am definitely aware of that, but if you aren't flashing a *custom* rom and are just using a stock rom with added files, does that still change the integrity?

Yes. Changing one *bit* of any file will always change the integrity.

If I could manage this, would it still be possible? I understand this isn't documented in AOSP.

Doing it (re-signing) with CalyxOS was quite a challenge the first time (but cool as hell to cut your own OTA deltas after the fact, without needing to unlock or flash user partition!), can't fathom doing it with Samsung esp considering AOSP is just the start, you still have binary blobs for the radio, etc. I never figured out how to get raw partitions out of Fastboot (which wouldn't require root, at least on my phones) to get those blobs with an unsupportive vendor. After that, then make the EDL image, which I assume ALSO has a crypto signature with keys not available to sign with (but, y'know, there are ways around everything).
Like I said, I just gave up and went with supporting a phone vendor that wasn't fighting me... much easier and I still have all my customizations (e.g. root + annoyance free) with the security of a locked bootloader.
I *THINK* (maybe gsmarena.com can validate) that the Pixel 6 is like the iPhone and includes the VZW bands in the unlocked version. Buying the unlocked direct from Google shows "set up with any major carrier later", so I assume that includes VZW too.
PS: the fingerprint sensor on front sucks major, and you don't get the 50MP camera in the API used by the open source cameras... I returned the 6 and went with a 5G... but I don't think that one includes the sub6/mmW bands in the universal version.

You would need the keys from Verizon to sign it yourself.

Alright. Thanks for your help
I'll try out a few methods and bump the thread if it works

If you had the Verizon keys you could just do the system partition mods, sign, and reflash with fastboot, or even better, a OTA delta image of the su/magisk package.
I think @qwiri 's question is could you use EDL to get a layer lower than the Android trusted boot- which you certainly could, or at least on a OP phone. But... you'd have to be able to do the entire image, signing EVERYTHING as you'd be replacing the keys, too. Totally possible, just hard- but THEN you'd have to reverse engineer EDL mode images, which I assume is signed by someone at QC. That may be possible- sign up as a developer, OEM, whatever, social engineer it. But probably more expensive than just buying a phone that LETS you flash keys without EDL (if you want trusted boot) or just unlock the bootloader to permit custom partitions (if you don't have the wherewithal to get an AOSP build environment and do it from scratch)
