2.3 rootable? Maybe not? Who knows....

Has anyone thought that maybe google has made 2.3 unrootable? Scary thought i know, but its kind of like a cat and mouse game with the developers and google/manufacturers with root patches.
Maybe google finally will put the nail in the coffin here?
WOOT. It's rooted, im happily wrong.

It's a developer phone, so why would Google want to make devs waste time trying to root.

could it be possible that Google enable root access by default, then?

Definately not.

Dev phones have always been rootable, i doubt that will change.
The phones that have trouble being rooted are always manufacture customized ones.

it's still able to fastboot oem unlock from what i've heard. Will be rooted same day it's available for purchase guaranteed.

I'd bet that it will be rooted BEFORE!

The developer build on my Nexus One is already rooted. I don't imagine the release build will be any different from all of the previous OTAs.

You are correct.

Samsung never locked their (Android?) phones. Personally I've installed custom ROMs on the Galaxy Spica and international S and both came factory unlocked. Unlike with some of HTC's devices you can flash anything you want without using exploits.

Your right, as of now I don't think Samsung locked any of their phones, but the only thing Samsung has on this phone is the hardware aspect. All the software aspect is by Google.

Then how do you explain threads like this (on the samsung galaxy sub forums):
[HOWTO] [REF] [FAQ] [Guides] [Tutorials] Flash/Root/ADB/ROM [MUST READ!]
It seems like you have carrier/sim lock and root confused. Just like nearly every phone on the market, they are locked. You will also need root to do anything that says "please root your phone". They do not ship this way...

I'm sure it will be rootable... Google doesn't want to block out developers

Just food for thought i guess, we cant know until its released anyways.
What exactly is fastboot oem unlock ?

that's unlocked for carriers with gsm...that's not root. Simply meaning it will work with at&t or tmobile by changing the sim card. Root lets you edit system files and a custom recovery to flash roms

Lmao no one so far in this thread should get one of these developer phones as you plainly do not understand what you are doing here when it comes to deciding what the difference is between root permissions and unlocked to all networks.
lets put it this way, if you are one of the above who are having trouble, dream on and steer clear from the prospects of rooting all together
unless that is you fancy yourself a very expensive paperweight?

This command unlocks your bootloader on the N1/N-S allowing you to flash custom roms, but visibly voids your warranty (bootloader screen shows that it's unlocked)

How To Guide Rooting the SM-F711B (on Version F711BXXU2AUI4) working

First of all:
I'm no Dev...just someone who likes to play lego.
From this point of view everything I post here is taken from somewhere else in the Internet and used by your own risk.
I've read a good startup here.
Hopefully this makes this thread clear enough so that i dont need to describe the whole procedure step by step.
(https://www.naldotech.com/root-samsung-galaxy-z-flip-3-5g-magisk/)
(1.OEM-Unlock,2.BL-Unlock,3.extract boot.img,4.patch boot.img via magisk on the unrooted mobile,5.patch boot.img.tar to AP&BL via Odin, 6.pray)
Anyways...here are maybe small hints to avoid a few traps.
a) Just do the oem-unlock in the dev-options (enabled by tapping buildnumber 5 times) is just half of the rent.
Afterwards i had to go in Download-mode (switch of mobile, press volUp+volDown and connect PC-cable.)
There appears a possibility of choice.
Press VolUp short: get the mobile on standby to flash the rom via odin.
Press VolUp LOONG: get the mobile to the menu where the bootloader can finally get unlocked. (Otherwhise every try to patch a rooted img will be blocked by bootloader-protection.)
Of course this can possibly be done via adb/fastboot commands.
Funny side note: OEM-Unlock-option will completely disappear from Dev-options and waranty is lost. Also the mobile stops to get Updates OTA which means that you have to update manually whenever a new version will appear in the net.
b) patching boot.img via magisk should work as described in many other magisk-rooting-manuals.
Flashing the tar back to the mobile via odin was little bit tricky.
It doesnt reach out just to provide the magisk_patched.tar to Odin just on the AB-line.
I had to patch it to BL too.
Cheers

When you boot into bootloader after unlocking, is the message something about "a custom OS can cause critical problems"?
As it stands now, the only reason I have to believe the US bootloader can't be unlocked (or isn't already) was the lack of an OEM unlock button and some cranky kid on the internet saying it hasn't been possible since the S7.
It doesn't make sense why I would have a warning about a custom OS if there is no possible way to install one, though.

@boot into bootloader after unlocking it...:
Yess you are right. Thats exactly the message.
Then you can enter the Device unlock mode again (long press VolUp) to lock bootloader again (then it resets automaticaly to factory-defaults and all work is gone.)
or
continue to flash something (short press VolUp).
Dont know about the US versions. Could be that there is a difference to my EU-models.
But either i rooted nearly every every mobile since the S2

I think you misunderstood what I was asking, but ended up answering it anyway.
It seems the message about installing custom OS versions may be a boilerplate for the bootloader, not any indication that it's possible.

naldotech.com, the link you provide is pretty clear about the process. What it doesnt say is what to do at the end. When you untick "reboot" in odin, and you finish flashing, your phone will stay in download mode. Then what to do?. Press power and volume down to leave and restart the phone? or, power and volume down, screen goes black imediately power and volume up, enter recovery and restart from there.? please someone ?

Press the power and volume down buttons for about 7 seconds and it will reboot

The USA version (snapdragon soc) can't be rooted as far as I know. There is no way to unlock the bootloader in dev options, at least on Verizon and that holds true even if you bought a unlocked phone. As soon as you insert a Verizon sim and the phone updates it's all over.
I had the same issue with the original Pixel. I bought it unlocked but before rooting it I allowed it to update like a fool. Luckily my son wanted the same phone so I gave him mine then rooted and installed TWRP before putting a Verizon sim in.
Back to Samsung...as far as I know you haven't been able to root the USA version since the note 8. The rest of the planet gets the Exynos SOC but we get the snapdragon and no root method works. My note 9, 10+ and z Flip3 didn't have an unlock bootloader option even before putting a sim in it.

Ok I might be off by a year or 2 but I can say with 100% certainty that the note 9, 10, 10+ and flip3 don't have an unlock bootloader option.
I bought all 4 from Samsung all unlocked and not tied to any carrier. First boot with no sim I checked dev options and there was no option to unlock the bootloader. My note 9 might have had the option in the menu but it was grayed out and I couldn't find anyway to make it work.
A quick Google search for rooting the snapdragon version of any of these devices essentially says "NOPE".
The only way to root one is to buy a non US version. If it has a snapdragon soc you're out of luck.

I didn't see that sentence in any of the posts but perhaps I just missed it.
It doesn't change anything either way. Anything is possible, even you somehow getting a device with this setting. That being said you also seem to be the only person ever to receive a USA device with said option.
It's hard to believe because it would mean the wrong firmware was installed (which makes no sense in itself) but with that firmware the device should have been a brick. The soc is completely different. It would be somewhat like trying to use Nvidia drivers on an AMD GPU... It just wouldn't work.
I dunno... I don't disbelieve you but I don't believe you either. It's just so far fetched for many reasons

I have a general question. I am unfamiliar with rooting/unlocking bootloader on Samsung devices. Is it possible to revert unlocking the bootloader and going back to stock traceless?

Partially. I just did that: I have AfWall running on my old phone, tried to unlock the Flip with this manual here in order to use the firewall there, did something wrong - and stumbled upon Netguard while searching what might have happened and decided to give it a try first. (Unless there is a custom ROM for the phone available, I have no other need for root or an unlocked bootloader.)
From what I could find on my Flip 3, you can unlock and relock the bootloader as you like - but as soon as you install a non-genuine bootloader (i.e. one chnaged by Magisk) you will trip Knox - and this cannot be reverted.
In such a case you can still re-lock your bootloader and unlock it later (on my phone, that "7-day-no-switch-indeveloper-options" routine kicked in, but you can circumvent that) - but Knox will stay in its state. From what I read this means some things will not work such as Samsung Pay, but I do not know the details (yet) apart from that it does not bother me ;-), and the nag screen during boot is gone.

Thanks for your reply. Kinda sucks. Never had problems with my former mobiles to get back totally to stock without traces. Guess I disregard rooting for now

Well, it's better than my Sony - there it is "once unlocked, always unlocked" with no way back at all
But I have to admit I understand the logic why the manufacturers do that, at least to the degree that they trip a fuse as Samsung does.
By rooting the phone, you shift the responsibility for the software state of the phone from the manufacturer to the user, so I think it is okay to implement something to make it clear to possible future buyers that it is or has been in that state.
(This does not include however all the other stones they put in the way of people wanting to develop or use custom ROMs!)

I remember I also had a Xperia Z3 compact.
Main reason for me for rooting, is the ability to use tools like tasker without non root restrictions or just trying customs roms without bloat, but usefull features. Guess u shouldn't have bought a Samsung lol.

Sadly there is no Fairphone mini or Fairphone Flip - or would it be Fairfliphone? ... Flipfairphone?... - yet (if ever), so the only current alternative would be Motorola. And the price tag for the Razr is simply too much, even if I personally think it looks better than the Samsung. Additionally, I do not know if they are in any way better when it comes to rooting or loading custom ROMs.

Unfortunately the SM-S908U1 cannot have its bootloader unlocked normally. Unless there's some other method or exploit, it will be locked forever.

There is an exploit out there. It has been in the news lately. It is whether or not it actually ever makes it to anyone that can use it to root our devices. But it does work for the s22. Here is an article about it.

I came across a defcon presentation called,
"Breaking the Android Bootloader on the Qualcomm Snapdragon 660".
It would appear that it is certainly possible to bypass a locked bootloader, Two interesting methods that were mentioned,
"The most commonly used approach is to access Qualcomm Emergency Download mode. This is a low-level emergency state boot mode, where diagnostics tools can be used to upload a signed “loader” payload to the chip, which can be used to modify the device’s partitions directly. While this approach is effective, it requires the ability to boot into the mode, which is not always made directly available to users, and access to a signed loader ELF which may not be available for the device.
The second common approach is to attack the device at a hardware level. By disassembling the phone, and connecting to EMMC chip on the board, it is possible to set the “unlock” bit in the configuration partition and gain unlocked access. Public resources exist which outline which pins should be connected to, however this usually requires some hardware knowledge and steady hands. There is also a high risk of irreparably damaging the device."
The rest of the presentation explains how the bootloader lock was bypassed via an exploit.
Ive also heard that exploiting flaws in Qualcomm's chips has become a common way to root bootloader locked devices, If root is all your after.

Possible to Downgrade From Android 11 to 10 on XT2113-2? If so, how?

I have a new XT2113-2 (TM) that is yet to be boot loader unlocked/rooted/etc. I don't want to do that until I am sure. I got this variant of the phone so I could unlock the bootloader, root, TWRP, etc and was afraid the "global" variant -3 might not work with USA 5G. The phone came with Android 11 installed (and has since auto-installed at least one security update). It shows the build as RZKS31.Q3-45-16-3-11 and the baseband ends with Kiev_TMO_CUST. I am using it on ATT (via Red Pocket) since TM service just sucks where I live. And I do get the 5G icon on it now.
But ideally, I want to get this to the original TM Android 10, which I think is shown here as the file XT2113-2_KIEV_TMO_10_QZKS30.Q4-40-95-6_subsidy-TMO_SPR_RSU_QCOM_regulatory-DEFAULT_CFC.xml.zip as I hope it will undo some of the "security" crap Google has added to Android with each successive release.
So I need to be sure of the following:
1. Can I downgrade from 11 to 10?
2. Is there some reason to NOT use the firmware mentioned above? Should I use retail US (RETUS) instead? I am not sure the differences (it would be great if that would permit me to use this phone on Red Pocket Verizon but the IMEI now shows as incompatible on Verizon).
3. Must I unlock the boot loader to downgrade? I know I must to do other stuff and I have the unlock code on hand and ready to put it if needed. If I must unlock the boot loader to downgrade, will I have to re-unlock it afterwards? And, if so, will I have to go through the same process of getting a code or will the code I have now work?
4. How do I flash to do the downgrade? I have the Lenovo Rescue/Smart Assistant installed on my PC and was able to download the stock firmware (I assume it matches what is on there now) and stashed it aside. But is there some other tool needed?
5. Once I achieve downgrade, what is the best way to avoid having the thing auto-update to Android 11?
Thanks for your help with these questions.

If you are going to take this phone to AT&T, you will not get 5G if you unlock the bootloader. The NR band will be restricted. Downgrading from 11 to 10 generally doesn't work either.
I can't answer the rest of your questions.

Thanks for this response. I do have it on ATT (via Red Pocket) now and it does appear to get 5G now. I have not yet unlocked the bootloader, was thinking to do it, but considering that it would cause loss of 5G I think I will not and will just return the phone. Wow!

If you are going to take this phone to AT&T, you will not get 5G if you unlock the bootloader. The NR band will be restricted. Downgrading from 11 to 10 generally doesn't work either.
I can't answer the rest of your questions.

BTW - have you any references on this behavior? I am wondering if this is something that would affect ALL phones with unlocked boot loaders (like Pixel, OnePlus, etc). Thanks for the heads-up.

WARNING: ONLY DO THAT IF YOU ARE REALLY SURE AND DO BE CAREFULLY. I recommend you: do it not.
By downgrading to an older software, the bootloader in many cases can be destroyed, so your phone is completly bricked!
I write this from EXPERIENCE. My amazon fire is completed bricked, when i have flash a older SYSTEM. It can't turn on, no fastboot, no recovery!

I suspect, but don't know, that all phones with unlocked bootloaders are blocked from 5g from AT&T. I know my kiev (RETUS) is.

Thanks. Yet another reason to dislike ATT, I guess. Sadly, in my area TM coverage stinks. And this phone will not work on Verizon (unclear why but they reject the IMEI). And getting the Verizon variant will preclude ever rooting the thing. So I really feel trapped!

Likewise

I always figured it was this
English Community-Lenovo Community
as my IMEI SV on the Metro/TMO variant is 05 rather than 07. Never tested with a locked bootloader though.

Bootloader unlocked Pixels work fine on ATT 5G, don't know about OnePlus.
