Reverse engineering 2XL VZW OEM switch? - General Questions and Answers

What's the status on reverse engineering a 2XL VZW? Surely there must be a condition where the OEM Unlockable switch can be set to on, whether by a network request or device status flag (which I would assume is out of limits for end-users to set). Or has the community already concluded this? By conclusion, I mean not a simple "no". I'm looking for a detailed insight on why us consumers are not able to OEM unlock our bootloader. I'd love to work on this if there is currently an ongoing project.

The OEM Unlock ( read: unlock ability ) flag is stored in Android's system file called build.prop.

Ouch, that's definitely tough to get into without having root already

How are you doing with editing build.prop?
I think through a PC you can get to the main section, but I don’t know how to do it.

build.prop is read only, no? You can probably *read* it from a PC and even direct on the device, but I don't think you can edit it

You can drag a copy of build.prop from your phone to a pc, change the values, and change it via adb via recovery

Well why hasn't this allowed us to root our P2XL's then?

I don't know why, but it seems to me that it might work, you just need to figure out how to get build.prop, change it, and send it back to your phone.
And you also need to find the lines responsible for OEM-Unlocking.

We're gonna need some actual sources here. I don't want this to be a thread of loose assumptions. No offense, but it litters the thread. I highly doubt Google will let Android owners modify a critical, core part of the Android system without root. @jwoegerbauer as well. If this is the case, then why hasn't this been posted anywhere?
By the way, I'm on topic for current Android versions; people who have upgraded to 10 and above or relevant versions.

All well-known manufacturers of phones in the past had to struggle with the fact that people who tried to root their phone's Android and got a soft-brick came to their service centers and demanded a free remedy.
So they pulled the emergency brake and secured Android against such tamperings. This brake is known as Android Verified Boot (AVB).
This means that all Android versions ( 8 and up ) implemented by manufacturers can no longer be modified without disabling AVB, which requires the booloader to be unlocked.

Lucky you, check the hspl/spl to see if it's locked or unlocked. If unlocked, contact the user, I mean The Living Legend called COTULLA and tell him about your phone. Actually, just contact him, he will tell you to do a few things and if someone can help in here, it's him. We owe him the HSPL for HTC WP7 1st and 2nd generation phones and the 1st Titan custom rom (DFT) among other things.

Security Unlocked probably means UEFI is off, or otherwise the bootloader is unlocked. Could be very wrong on that, though. Either way, doesn't matter since we don't have a 8X ROM to cook and modify.

This is so very serious and huge news...if it has the UEFI unlocked like an ES is supposed to be. Can you access the file system/mount device in bootloader mode?
Also, could you try and install a WP7.* xap file ( just download an app/game xap from xda or this one from here, not a sys messing one) on it? Just copy it inside phone's int meme and click on it, the installer ''should" handle the xap...
BTW,if tha XAP installs and runs I could say that phone is worth its weight in gold...cough...cough...for us and MS.

Email it to you as an attachment and try to open it on the phone.
Also, depending on your time and availability, you could contact E:V:A by PM or posting in this thread http://forum.xda-developers.com/showthread.php?t=1934388 so you could dump whatever is on that phone.
Wow, this is real HW porn! I posted partition dump instructions in that thread, but I now see that this could be even more useful in the future, for allowing us to have unlocked bootloaders with all engineering features intact. So if you could somehow get us, either a full "disk image" or preferably all of the individual partitions, that would be awesome!
All the tools needed can be found in the links of my footer. It could be that you need to install some additional USB drivers as well.. But we'll see.

EDIT: I got into the 'bootloader mode' (not sure if it is). I plugged it into my notebook and it installed Windows Mobile Device Center (forgot the exact name lol) and the 'Serial' mode changed into 'USB'. ?

It's not that hard and it can't be done via remote support unless you have two machines ( you need one running linux and the other one with a IM that has video also). Your best shot is to find a friend that knows Linux and has a Linux distro installed and "beg" him to do it for you.
Also, it would be wise to keep secret the rest of the info about the device. It's been known that MS roams XDA and this thread isn't good news for them, just let me put this in another way : it's like you've got a WIN8 key generator in your hands ( though this is not a solution to activate W8). Stick to PM the devs.

I am trying to find what part of a file is being read for an on/off tag, so I can modify it to bypass the bootloader. The file that is read is just a data file, full of 0's and 1's. As far as I can tell, the system reads the specific flag using an offset-length system, but the program that runs it is compiled and a few megabytes, plus I have no idea what I am doing with assembly.

The file is named "misc". I am not sure which partition it is on, probably the bootloader's (mmcblk0p5), since that is what uses it.

I had a link, a few months ago, that was notes from an assembly programmer to another team, for another similar device, but I don't have the link anymore, got lost when I upgraded to windows 7. From what I understand, the bootloader looks at the tag in the other file, if it is set to true, it does a signature check on the boot partition. If not, it boots with no security, aka unlocked.

Boot Animation

There two level of boot animation of an android device, right? And to change the system one is to go to /system/media or /system/customize/resource to change the boouanimation.zip. But is there any method for me to change the animation show earlier than the system one ( perhaps it is from /boot ? I dont know, I want to search for clues but I even dont know what the keyword is ).
I am using an htc 2014 phone btw.

To install a modified bootloader, usually it needs to be cryptographically signed, and only the OEM has the signing keys. So in practical terms, it is not possible for us users to modify the bootloader in any way.
There are some cases where some of the files used by the bootloader are stored on user-accessible storage, and in this case modifying those is feasible. But this is more exception than norm, and you'll need to read through your device forums to see if anyone has investigated this.
I will take a look in it. Thanks for your reply after all!!!

Change Splash/Boot Logo for OnePlus 7 Pro???

Is there currently a working solution to change boot logo/splash on the OnePlus 7 pro???
I have scoured the internet & XDA and haven't found anything on the subject besides a general guide for Snapdragon devices and SplashInjector. I used the directions on the general guide to extract (for op7pro we have all these) Splash, LOGO_a & LOGO_b and will attach files. However the OP of said thread hasn't been responding or continuing to make/find solutions. Thread can be found here https://forum.xda-developers.com/t/...en-for-snapdragon-devices-splash-img.3470473/. SplashInjector is a git bash program that runs on Linux and to a good extent Windows, created by EthanBanker2042, @makers_mark, boblagus but it only works for OnePlus devices up to the 5. I used it to mod the splash of my OnePlus 5 on Windows and it worked great. Find it here https://forum.xda-developers.com/t/tool-splashinjector-op5.3650374/post-73282055.
I was hoping to find a dev or someone with more knowledge/skills than myself who has or is willing to create a solution for modding the splash/boot logo on our OnePlus 7 Pro devices. I imagine it would be somewhat more complicated than on previous devices due to treble A/B structure. I found in /dev/block/bootdevice/by-name/ 3 related files: 'Splash', 'LOGO_a' & 'LOGO_b'. My guess is that LOGO_a & LOGO_b are the same, and are the actual splash image of the OnePlus logo in the center with "powered by Android" at the bottom and 'Splash' might be the bootloader unlocked screen, however I'm not totally sure. I used FX file explorer to view binary of the files and the 'Splash' was, as far as it would show (file too large to completely display), nothing. However, the LOGO_a/b files state "Splash" at the beginning and contain actual data beyond 0's.
If anyone has any relevant information I would be very grateful. I am ready and willing to set time aside to help/work on this as much as needed.
Thanks in advance
*My device that files were extracted from is a GM-1910
Attached is the 'Splash.img' extracted from /dev/block/bootdevice/by-name/Splash.

When I say modified secured. I meant it's using an android system. But have very limited function. Like don't allow user to add apps. And no wifi or cell services. No memory slot. Only way I could think about adding apps to there is through an OTG cable

It would help if you would just post more informations. For example, if I want to flash a file on samsung, I would use Odin. You cannot use Odin with other brands, like xiaomi, Huawei, oneplus. Post as much information you can. Do you want our help or not? So far you ve only said that the device is secured. That's not helpful at all, given there are many ways of securing a device, some devices have more means of securing them. What methods to bypass said security work on some and don't work on others. So, if you want help, post as much information as possible.

It would help if you would just post more informations. For example, if I want to flash a file on samsung, I would use Odin. You cannot use Odin with other brands, like xiaomi, Huawei, oneplus. Post as much information you can. Do you want our help or not? So far you ve only said that the device is secured. That's not helpful at all, given there are many ways of securing a device, some devices have more means of securing them. What methods to bypass said security work on some and don't work on others. So, if you want help, post as much information as possible.

1st, he said in it post #5.
2nd, with a proprietary protocol on the USB port? That would be a major flaw, considering what this device is meant for (providing entertainment to inmates).
