Permanently Lock Boot Loader - Xperia Z3 Q&A, Help & Troubleshooting

Good Morning,
/* Intro
I am new to this forum and I have just received my Z3. Was made week 49 of 2015. So far this is the best phone I have ever owned even though its an "old" device (I had an Xperia E4g prior to this, and before a Samsung Galaxy Grand Prime).
Anyway when I was deciding on my phone, I wanted to get the Xiaomi Redmi Note 3 Pro 3/32Gb but the shipping was 25days and I am generally iffy about devices that come in regular post. I pulled the trigger. Snappy phone no complaints at all.
End Intro
*/
Now with Xiaomi to get your bootloader unlocked is a pain in the behind and I believe it takes two weeks. What I want to know is can I permanently lock my bootloader on my Z3. I live in a region where phones get stolen and flashed, am happy with Lollipop and will wait for MM to come out and get it via the official update. I would like to take advantage of Device Protection but as we know any smart thief flashes custom rom or recovery rom to get around that. I am assuming if my boot loader is locked permanently that would increase my chances of recovering a device should it go missing. If that is the case, how do I lock the bootloader permanently.
Weird question especially on this forum I know but if I am going to do custom roms it will be with a secondary device not this one.

I guess no one has information on this?

Even with locked bootloader phone can be flashed.

Thanks for the reply.
As you can tell I am new to this.
That said I was under the impression that the protection was built into the bootloader and turned USB of in lock down.

Locked bootloader means that you can't flash custom rom but phone can be flashed with stock rom.

Thats false. You can flash custom stock-based ROM's with a LB (locked bootloader), but you cant flash custom kernels unless you have a UB (unlocked bootloader).

What happens in Lockdown?
Essentially, Lockdown will render the device completely useless unless you have the correct Google credentials to validate the device:
• All running applications are stopped.
• You can no longer maximize the notification panel.
• Incoming calls are sent to voicemail (if available).
• Outgoing calls (except emergency calls) are blocked.
• The USB port will only be available for charging. It will not be possible for a PC or Mac to detect the device.
So how does the device get flashed?

Now I realised that you are talking about mxtp. When in lockdown the only way to access the phone is signing in with your Google account.

I have a Galaxy s21 snapdragon with a locked bootloader, can not be unlocked. I have flashed many custom roms in my days on unlocked bootloaders but this is the first ive heard of flashing custom stock based roms and id like more info into doing this if youd be willing. How would i go about it?

You've stumbled on a very old Sony thread my friend, your comment is the first in 6 and a half years .
What I was talking about wouldnt be compatible with the latest Android versions with a locked bootloader anymore.
Disregard my comment in your case.

Help a Xperia noob out with some questions please :L

So this is my first xperia device since the Xperia Arc was released way back when, and I have been using HTC phones. Which are WAY different in terms of Rooting / Unlocking / Etc.
So long story short, What I want to know is what Can I currently do to the Xperia Z5? I see there's no custom ROM's yet which is expected , but I see mixed results about unlocked BootLoader & Root , the main thread says that a bootloader hasn't been achieved, yet there's a few root methods which have been successfully completed , requiring an unlocked bootloader, so naturally you could see the confusion..... Can someone point a SONY noob towards the right direction in terms of bootloader unlock / rooting? Running the E6653 ( not sure if there's variants )
Basically you currently need to unlock the bootloader to to get root. And doing so loses some features which u may possibly never get back. So most people are currently waiting for another way around to be figured out

My heart literally dropped as I read this..... Because I already unlocked the bootloader. I'm assuming it's the bootloader unlocking that destroys some features? If so , which ones?
And how can I tell if they were actually destroyed / bootloader unlock actually worked
Unlocking the bootloader on Xperias will delete the device's DRM keys. These keys are unique per device and once gone are gone forever. They're needed for Image enhancements like X-Reality/Bravia/Super-Vivid and some camera features too - low light and noise reduction algorithms I think. Sound improvements (ClearAudio+...) too.

Well crap lol, is there any way to actually make sure that the DRM's were deleted or if the bootloader unlock was actually successful? I still have a few days to swap the phone out if anything goes wrong ( Bell wouldn't be able to tell a bootloader unlock ) , I haven't had enough play time with the phone before the process to actually see a difference with the camera, I read somewhere that if TrackID works, than it's not unlocked, is that true?

Looking to buy the Galaxy S7; couple questions

Hello,
I'm planning to buy this (Exynos) variant of the Galaxy S7. It has great specs and the availability of custom ROMs pleasantly surprised me. Therefore, I have some questions:
1. How do you go from full stock to being able to flash custom ROMs? Is it difficult to unlock the bootloader? I'm used to Nexus devices where you'd reboot to bootloader, fastboot oem/flashing unlock and that's it, but the procedure is certainly different on the Galaxy S7.
2. Are there any things I should be aware of? e.g. Can I brick my phone with flashing something or doing something that wouldn't brick some other phones?
3. Is it possible to return from custom ROMs to full stock? I guess I won't have KNOX back since that's a physical detail AFAIK, but I can live with it, I guess. Modded stock ROMs can also be flashed from TWRP, right?
4. I was really surprised that the Exynos variant got so much dev support. Normally I would expect that from a Snapdragon device, but the Snapdragon variant's BL is locked. How come Exynos got so much dev support and ROMs with practically no issues on this device (and some other like the Galaxy S6)? From what I've heard in the past, the Exynos phones aren't exactly the most dev-friendly ones. What has changed since? I may be completely wrong though
That's all for now.
Thanks in advance!

You need to flash TWRP custom recovery (Instructions in the TWRP thread)
Unlocking the bootloader is a simple toggle switch in developer options

Once KNOX is tripped that's permanent, but you can return to stock using ODIN and a stock ROM from sammobile or other sources scattered around the forum

So, to unlock the bootloader, I literally have to toggle "Enable OEM unlock" in developer options? That's it? I'll have this switch regardless if I'm on Marshmallow or Nougat, right?

Correct
Don't make the same mistake a few members have, and disabled it once they had TWRP installed, you need to leave it unlocked while you are running custom

It gets stuck trying to boot with custom binary blocked errors iirc
Then you need to spend time working out how to bypass the lock and reflash stock etc
If i was you then i would keep the s7 with the stock rom because this stock rom is pretty awesome and i like having the secure folder functions etc.

Question [Q] Why do we need to unlock the bootloader before rooting?

hi! so i just bought my rog phone 5, coming from xperia z (yeah i know). so based on my experience using xperia phone, rooting doesnt require unlocked bootloader, right? or did i just forget it coz im using custom roms?
im just not ready to unlock the bootloader and I WANT ROOT. theres so many ads

AFAIK, unlocking bl is a prerequisite for rooting. Or else, the device wouldn't be able to execute 'fastboot flash' or 'fastboot boot' adb commands.
As for the ad issue, try 'dns.adguard.com' w/o quotes as private dns address (dns over tls).
because you need to modify the boot partition by flashing the patched boot. hence it has to be unlocked. otherwise you will not be able to flash the patched boot.
as simple as this.
By default, the bootloader only supports official signed images from the manufacturer. Since no engineering bootloader is available and we don't have the signing tools, the next best thing is to disable the restriction.
thanks everyone! this sure cleared things up. anyway is there a available custom rom? like cyanogenmod for phone 5?

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

I did as you mention but it didnt work. It made me reset the system. But I Fallowed the naldotech.com guide. At the end, being in dawnload mode, I pressed power and volume down, when the screen got black I pressed power and volumen up, I entered recovery mod, cleared cache and re- started the system: Voila my phone is rooted

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.

I have to be a little skeptical when my rooted Note 8 came out a year after the S7. There are other reasons, but they tend to make the trolls restless. We'll skip them.

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.

BL unlocking/custom ROM Question: What is permanently lost if I do that?

Hi,
Just grabbed an Xperia 5 II on a great deal and I'm loving this device. It's an A002SO. I have noticed in other threads that there is some loss with original functionality of the phone (maybe Dolby or some other features are broken even if phone is restored to stock). Is it true? And if so what features are broken.
I noticed that Xperia camera software are available for other roms too which is great but what about device fingerprint and BL unlock sensing protection for banking apps? (I am not interested in rooting the phone after flashing lineage/AOSP roms but more concerned about the broken safety net in-case I go custom ROM route)
Also, is there a risk of losing IMEI with all this process? Not talking about crossflashing here but would love an AIO guide about BL unlock > recovery > ROM and the Back to stock locked bootloader guides if there are any.
Thank you!

I have a different model, but I recently went from stock to Lineage OS, then back to stock. I haven't had any issues. Dolby works, my data/LTE works, and I can still use my banking app just fine. Fingerprint detection was a bit more finnicky with Lineage OS, though.
I should also note, I'm currently rooted with my bootloader unlocked, and still no issues.

I gave up in the end because my device is Japan Softbank with bootloader unlocking not allowed. Crossflashing instructions have alot of "you can", "I think" but no definite root-to-fruit guide so I may convert it to global model and BL unlock without losing imei / 4G. Thank you for taking time to write the clarification.

I don't actually know if that would work... I don't mean to give you another indefinite answer, but I tried that once on a Japanese Xperia 10 II. I know it's a different device, but it may still apply in your situation. I would still try it, though. Worse case scenario, you have to use Sony's repair tool to get back to stock.
(Also, if you're interested in a non Japanese model, I am currently selling my 5 II.)

I am from Pakistan so it's gonna cost me double the actual price to pay customs taxes and get it cleared for use in-country. Our country has a rule about only the devices which are approved after paying hefty taxes, are permitted on Pakistan's cellular operators.
This was discussed before, in short you seem to lose out certain manufacturer keys and your phone remembers you have unlocked its bootloader before. As for functionality, iirc they seem to come back after relocking.
