Question Any solution to remove the annoying bootloader unlocked message ?

[zinou213]

Hi everyone, this question is for developers who have some bases in hexadecimal programming, I would like to know if it is possible to remove the message after unlocking the bootloader, I had an LG V20 H990DS and I had followed the tutorial on this thread and it was working fine, is there a similar solution for the ROG 5.

That depends. I modified a Teclast T30 bootloader (Mediatek garbage) that forced a delay and printed an orange error message about the bootloader being unlocked. A bit of Arm64 reverse-engineering and I shorted the delay to 0ms (none, basically) and just cut the string short (null-byte) and it works fine on my junker tablet. I've just bought an ASUS ROG Phone 5, getting into it, but I'm nervous about touching anything without, say, TWRP or without knowing how to do a full raw backup and restore.

Thanks. Just waiting to figure out how to do a raw backup and restore, then I can get to it. If TWRP isn't required to do a raw backup and restore, then I can also begin work on porting TWRP. I've some experience, but not the most when it comes to TWRP porting.

*Edit* I'd like to add, reverse-engineering the ASUS Unlock Tool seems to show the limits on unlocking may be artificial by ASUS. Uses a call-home to fetch data to unlock with. The logic though may be in another castle, I mean package. The FOTA app does the same thing.

*Edit* By the way, does anyone have the exact message that displays about the bootloader being unlocked? I might be able to begin work tracking it down to remove as well as any delay (if there is one).

Some mods target the abl.img (possibly Android Boot Loader) so that may be one place to start. I personally never bother with backups, so I didn't really consider that. All of the data for my apps is synced and everything else is installed from Google Play. I guess that would be a bit more difficult if this were my primary phone.

The text for fussing is in tz.img, or at least it is *one location* with it. But since this is a stupid Tencent version, I can't flash anything to test, otherwise I'd have done it by now. Ah well. Sending the Tencent POS back.

OK , So the possible partitions to see deeper are abl.img and tz.img, can anyone help us with some more informations to remove this annoying message, thanks to all for your participation

Use payload_dumper and a hex editor to compare the original to yours.
