Correct way to lock the bootloader? - Google Pixel 5 Questions & Answers

What is the correct steps to factory reset and lock the boot loader.
I don't want to brick the P5.
I am trading in the P5 and I am second guessing myself on the step for this method.

Use the Android Flash Tool. It's foolproof and gives you the option to relock the bootloader and wipe data.
To manually lock the bootloader, reboot to bootloader, and use ADB:
fastboot flashing lock
If you intend to manually flash the factory image via ADB, make sure this is the LAST thing you do.

Kool, I did not know that the flash tool would do this.

Yep. You can force flash all partitions too, as well as disable verity and verification. It's honestly the easiest way to factory flash.

[Q] From TWRP back to stock Recovery & locked Bootloader, keeping root & Custom ROM?

[Q] From TWRP back to stock Recovery & locked Bootloader, keeping root & Custom ROM?
Hey everyone,
around new years eve I found out that the Android Device Manger's remote wipe is not secure enough for my needs, as it doesn't wipe the data (pictures, app data etc.) on the virtual "sdcard" of the HTC One's storage. So a potential thief could easily access my Custom Recovery and simply by flashing a custom ROM gain access to the data.
I described the problem in more detail over here: http://forum.xda-developers.com/showthread.php?t=2598154
While unlocking a friend's phone I noticed that during the "fastboot oem unlock" procedure all data is wiped from the device. Something I totally forgot about.
This behavior is exactly what I want if my device gets stolen.
I can accept the hassle to deal with a temporary custom recovery or ways to perform an online nandroid, without the comfort of a Custom Recovery and having to lock the Bootloader again after every Custom ROM upgrade. (Yes, it will be a pain in the b*ttocks, but I want my data to be inaccessible.)
What do I have:
HTC One (international GSM version)
HTCdev.com unlocked
SuperCID
TWRP as Custom Recovery
Rooted CustomRom (SinLess in my case) installed
What I want:
Bootloader to be locked (so that you can't simply flash a Custom Recovery)
Stock Recovery (so that you can't simply flash a Custom ROM)
being able to make a nandroid backup, before unlocking again
keeping root and the Custom ROM
keeping SuperCID (req. for SinLess)
I don't want to make a mistake, so I am asking for some guidance. :angel:
I am assuming correctly that just flashing the Stock Recovery image is enough to get rid of TWRP?
I know that this temporary loading of a Recovery was a thing some time ago (HTC Desire), but I haven't looked into it for years now.
Is this still possible and how do I do it? Does this allow me to perform a nandroid backup with a locked bootloader?
Otherweise: If my bootloader is locked and my recovery reverted to stock, is there a way to nandroid backup my HTC One? I know about the App "Online Nandroid" (Play Store Link) that allows to perform a nandroid backup on a rooted phone without booting to recovery. Does it work with the HTC One?
What happens if I "relock" this htcdev.com unlocked phone? Will I simply be able to use "fastboot oem unlock" (followed by a full wipe) to unlock the bootloader again? Or are there more strings attached, like requiring htcdev.com again or any other problems?
Is the CID setting affected by any of this?
Am I missing something else?
Will the following routine be my way to go if I want to flash something (ROM, Kernel etc.)?
Backup Apps: Titanium Backup
Perform full nandroid Backup (App: Online Nandroid?)
Pull nandroid Backup, Titanium Backup Files and all Data from /sdcard/
Unlock phone --> result: full wipe of device (no big deal, as everything is backed up)
Flash Custom Recovery
Push Installation files for (rooted) Custom ROM, Kernel etc.
Push Titanium Backup Files
Install (rooted) Custom ROM, Kernel etc.
Boot Phone, set it up as usual and restore Titanium Backup
Push Data back to /sdcard/
Flash Stock Recovery
Relock Bootloader
Is this correct?
Or did I miss something?
Thanks in advance
noone? :angel:
I would highly appreciate any guidance on this. Thanks in advance

Well, instead of doing what ur trying to do, you can encrypt the phone. A full phone encryption will prevent any changes made to any of the phone partitions. Thus, a ROM cannot be flashed in TWRP recovery, which serves your purpose and is easier than what u mentioned. However, decryption will factory reset the phone.
To answer your points:
1. Yes, flashing the Stock Recovery image will get rid of TWRP. But, im not 100% sure whether the ROM will work properly on stock recovery
2. You can definitely load a recovery without flashing it. Not tried on a locked bootloader. Sorry
3. Not sure whether the Root will be maintained after locking the bootloader and flashing stock recovery. If it is, then the Online Nandroid will definitely work
4. No strings attached. oem unlock will definitely do the trick
5. Nope, u will still be S-OFF. No CID is changed

Since you have s-off just use revone to unlock the bootloader without wiping data.
Procedure to lock things down:
Code:
fastboot flash recovery stock_recovery.img
fastboot oem lock
Procedure to return to unlocked/custom recovery:
Code:
adb push revone /data/local/tmp
adb shell
su
cd /data/local/tmp
chmod 755 revone
./revone -u
reboot bootloader
fastboot flash recovery twrp_recovery.img
You could also do revone with file explorer and terminal emulator and then flash TWRP directly in the OS using Flashify. This would allow you to return to unlocked with custom recovery without needing a computer.

Well I looked into encryption and it would require to use a PIN or Password lock instead of the Patternlock I prefer.
There was some mod that derived a PIN from a pattern input to work around this limitation, but I don't think it's the best idea to fiddle around with system files of that level.
But after reacing cschmitt's post, about the fact that there is a way to unlock the bootloader without wiping, my whole thoughts from the initial post are pointless
I guess using Android encryption is the only way.
Is it possible to use phone encryption together with location-based (wifi-based) disabling of the encryption using the "SecureSettings Plugin" for Tasker?

Wow! Thanks for pointing that out.
So the bootloader lock does not offer the sufficient protection that I am looking for
Unless...I return to S-On each and every time a I want to flash a rom or an Update.
Can I be sure that with S-On revone does not work to unlock the bootloader without wiping?

The locked bootloader still offers the same level of protection. Unlocking via fastboot still wipes data, and the only way to unlock it via revone (which does not wipe data) is to be booted into the OS, which is protected by your password/PIN/pattern lock. (You might want to disable ADB while not using it, but in current versions ADB require authorization before it will connect to a new computer, and that would require unlocking your device with the password/PIN/pattern in order to approve the connection.)
If you have a locked bootloader with stock recovery it's not possible to use revone to unlock the bootloader via fastboot or adb, so you're still protected.
You cannot use revone to unlock bootloader if s-on.
An whatever you do do not go back to s-on.

There have been a number of cases of going back to s-on with locked bootloader and then not being able to unlock the bootloader again or regain root, so could not s-off again.

I thought the revone command was operable via fastboot/adb from the bootloader as well.
That is good news.
So one question remains.
Is there a way to access data from the stock recovery (maybe locating via "adb shell ls..." and then using "adb pull...") when s-off with a locked bootloader?
Assuming adb is turned off in the OS (developer options) if not used?
If this isn't possible this seems to be the perfect solution
I thank you sincerely!

All that's available in stock recovery in the ability to flash an HTC signed zip (official OTA, for example) and to factory reset.
There is no backup/restore/adb access/file manager like in a custom recovery.
Perfect :good: :laugh:
Sorry for asking that many questions, but as user the motto is "better safe than sorry".
I unlocked and s-offed my HTC One around June-August 2013 and besides a quick TWRP update here and there and a monthly ROM upgrade there was absolutely no need to fiddle around with it more.
Aftermarket development has become that reliable that it's actually possible to find a good "set it and forget it" daily driver setup.
And since I am not a developer and don't deal with those questions on a regular basis, I'm always not 100% sure if I get all the facts right.
Thanks for helping me out with this one!
I'm going to try it next weekend or next week: Going to backup my data and simulate a potential theft with the locked bootloader and reverted to stock recovery. Remote-Wiping the device, unlocking the bootloader conventionally via fastboot and making sure that this wipes all user-data on the phone. And then I'm going to give that booted into OS, revone unlock a try and simulate a potential rom upgrade, just as you described it.
Right now I just can't risk my daily driver phone, as I wouldn't have the time to set it up again.
Thanks for your extended help
Finally feeling secure again on Android.

Re-Lock bootloader?

I unlocked my bootloader, installed twrp and several roms to try them out, then decided to go back to stock. Currently have OOS 3.5.4 installed with stock recovery (that came with the toolkit). However, whenever I try to lock the booltloader again, the phone won't boot up. It will bootloop, or just stay off with the led glowing white. I tried to sideload the stock ROM from OnePlus, but it fails after about 45% completion. I tried both 3.5.3 and 3.5.4 and both fail after about 45%. The only way to get the phone to boot again is by unlocking the bootloader again, then it boots just fine. Tried unlocking with the toolkit as well as fastboot oem lock. Both give me the prompt on the phone, then wipe the phone and go into the bootloop.
Any suggestions on how to re-lock the bootloader? I want to be able to get the OTA update, which I think will fail with an unlocked bootloader. Note, I have also tried loading the Nougat update from settings - system update - local upgade (both full and update) and they also fail to load shortly after booting to recovery.
Thanks,
TR
Instead of using the toolkit, try just doing it manually.
fastboot oem lock IS the correct way to lock the bootloader.
If you're running into all those issues, try to reflash the stock rom from the official site. OR try this
NOTE: This WILL wipe everything on your phone so make a backup first!
First Unlock booloader​1. On your phone go into Developer screen (Settings --> Developer Options)
If you don't have this go back to Settings --> About Device. Tap "Build number" 7-10 times to unlok developer options
2. In Developer Options turn on "USB Debugging" and "OEM Unlock"
3. Open ADB in command prompt and go to the directory where ADB is.
Type adb reboot bootloader
4. Once your device is in fastboot mode, type in fastboot devices to make sure your device is listed
5. Type in fastboot oem unlock to unlock your device bootloader
You can check to make sure it was properly unlocked by typing in fastboot oem device-info.
6. Reboot into your system
Files we need​7. Download the following files:
TWRP - https://build.nethunter.com/test-builds/twrp/oneplus/twrp-3.0.2-0-oneplus3t.img
No-verity-opt-encrypt - https://build.nethunter.com/android-tools/no-verity-opt-encrypt/no-verity-opt-encrypt-5.0.zip
Magisk - http://tiny.cc/latestmagisk
Phh-Superuser - https://forum.xda-developers.com/attachment.php?attachmentid=3988488&d=1483407725
Latest Stable Nougat Rom - http://otafsc.h2os.com/patch/amazon...s3TOxygen_28_OTA_035_all_1612310259_2dc0c.zip
8. Copy all the files to your phone (keep the original on your pc just in case)
9. Load back up to fastboot mode
In ADB type adb reboot bootloader
10. Flash twrp img we downloaded above by typing
fastboot flash recovery twrp-3.0.2-0-oneplus3t.img
11. After this reboot into the system
Install all of our downloaded files through TWRP​12. Now boot into recovery by issuing the following ADB command
adb reboot recovery (you should go into TWRP)
13. Once you're in twrp flash the "no-verity-opt-encrypt-5.0.zip" file OR you can format the data partition to f2fs to prevent the dm-verity error.
14. Now install the stock stable nougat rom we downloaded above
15. Do a factory system wipe / cache & dalvik
16. Install magisk through TWRP
17. Wipe cache/dalvik
18. Install phh SuperUser
19. Now reboot into the system normally.
NOTE: This *COULD* take a while since you did a clean install of nougat so just be patient and you should be good to go after this.
Thanks for the reply.
I did do fastboot oem lock, and it results in an unbootable system. fastboot oem unlock makes it bootable again. Not sure why. Also, whenever I do adb sideload <any_rom> it fails after about 45%. Not sure what's happening. Your instructions would get me to Nougat with TWRP and an unlocked bootloader, which may be what I end up doing, but I was trying to get back to fully stock, and locked again, so that OTA's will work properly. If nothing else works, I will go the route you suggest above.
Thanks again!
I just figured I'd try to get you to a working system/phone. After you get all that working you can probably lock your bootloader back to default. Now, I'm not 100% sure, but I believe that if you have a custom recovery you will need to restore that to stock as well before setting the bootloader back to locked.

I also have the same problem, after the bootloader lock the phone does not start.
I tried with all the possible procedures, also even the rom flash in local and sideload it does not work, It comes to 45% and then fails.
we will highlight the problem, so everyone will know and maybe there is a solution

But of course, you can't relock phone with a non standard recovery. Replace TWRP with the ROMs real recovery and relock will work again.
That's what I figured. Thanks for the confirmation.

You can a unbick tutorial. It worked for my OnePlus 3T. Just search up How to unbrick (whatever OnePlus device you have) on Google. Then follow all the instructions carefully. If you need help with it I could try to do a remote session with you. Edit: It will erase all data and you will boot with oos 3.5.3 ( I also had the same issue as you. But I couldn't install any zip with stock recovery or adb side load.

Only if you have modified the phone in some way or another (like rooting and installing twrp) before trying to re-lock.
If you keep it stock, you should be able to re-lock. Or else, just use the Qualcomm restore method to re-lock.
tried this
OK what i did was when the phone was starting and vibrating I push the power bottom and volume down bottom at the same time ,then i connected the phone to the PC,from the panel in the phone there are 3 categories to erase everything on the phone I did it all(1,2,3) and then I put the phone in ADB mode from the control panel in the phone,After that I flash via fastboot the original .zip from one plus for the version 4.0.3 (1.4 GB) ,when it finished I restarted and the phone started normal again,I hope this help someone alse,I was so desesperated:silly:.
I think the problem in re-locking it is the modified boot image. Locked bootloaders don't support those.

OTA update over Magisk? What's gonna happen?

If I have a P9 on Nougat B391, I receive an OTA, am currently rooted on Magisk v14. If I install the OTA anyway? What will happen? I know I will lose root, but will my bootloader be relocked? Am I going to lose any data?
Would like to know what will happen next as I am thinking of installing it. thanks!
there are 2 posible outcomes, maybe 3.
1. update will be successfull and you will lose root, twrp, bootloader can be locked too, but on fastboot it will shown as unlocked, if you cant instal twrp, then you need to unlock bootloader even if there is tuped unlocked.
2. update will fail and you will be back on same build you was.
3. never hapened to me, but are possible, that phone got bricked!

IMO, (2) is most possible utcome. (3) may happen if you force DLOAD and other manual methods.
Better:
1) unroot by Magisk Uninstaller, find the download link in the post https://forum.xda-developers.com/showpost.php?p=74913863&postcount=1
2) flash from TWRP original stock boot img
3) wipe Dalwik and Cache from TWRP
3) flash from fastboot original stock recovery
4) let it make OTA update but select in the System Update settings to use Full (not differential) update - it will not delete your apps and settings
Of course, you will loose root and TWRP but bootloader will remain unlocked and you will not risk bricking the phone.

Magisk Uninstaller does not wipe your phone.
However, unlocking or relocking Bootloader (from Fastboot) triggers Factory restore

Did you try blank flash yet?
Forget everything, and try to manually boot into TWRP.
Download TWRP for payton from the TWRP site (Img and Zip files for V3.2). Download and install Minimal ADB, Copy TWRP img file into the ADB install directory, put your phone into bootloader mode, connect to PC and run "fastboot boot twrp-3.2.3-1-payton.img" on the ADB commandline. The phone will boot into TWRP. You'll have to mount the storage and copy the TWRP .zip file into your phone and flash that from TWRP. Now you got TWRP flashed as the recovery.
Now it's a matter of flashing a ROM. I'm not really sure about stock firmware because i haven't flashed them before, but if you want to flash a custom ROM, make sure you flash TWRP after flashing the ROM without rebooting into system or recovery.
PS: I assumed you know how to do this with this explanation. Let me know if you need more instructions.

Question Can't find valid os??

I was locking my bootloader to try to reroot and pass safetynet. So, I factory reset it, set it up, and then went into the bootloader and typed "fastboot flashing lock". I selected yes to confirm the locking of my bootloader and then my phone rebooted. But now my phone says "Can't find valid operating system" and I can't boot into Android. i was able to unlock the bootloader again but now i don't have magisk installed and I can't even boot into Android to install anything. Is there anything i can do to fix this?
Yes, if you're bootloader is unlocked then you can fastboot flash (or use Chrome web based Android Flash Tool) factory images from https://developers.google.com/android/images
If you want to root extract the boot.img from the zip and patch with Magisk, then fastboot flash boot magisk_patched.img after you boot the phone once on stock unrooted kernel.
Thank you. I did it with the flash tool. Then later, it happened again and I realized I could use the boot.img. I'm glad these Google pixels are noob friendly.
Never lock your bootloader unless you know for a fact that you are on bone stock OEM firmware.
