Lock Bootloader With Custom Firmware

Consider this a PREVIEW, everything is at your own risk. Needs some cleaning up and more scrutiny.

Please test.


Here’s an example of what you can make:

I only tested with the v1 f21 firmware.

There is a check script, so you can verify before starting the process.

Also, this whole thing in general can kinda be forked into a crb like tool for Linux (yes, I know crb is already technically Linux based).

Haha q25 vulnerable too

It seems from this not like that:

That was on the f25 thread, I’m talking about zinwa q25.

Does that mean we can get it to work in the US?

No relation

Here’s another:

if i use dumbdroid and lock the bootloader, will it pass play integrity? (no root)

No.

First of all, thanks

I have a question and I hope I’m not straying from the topic. This tool can help solve the problem on Lom S9 devices Or the future mini-dumber who are blocked from using the app Google Wallet One of the reasons for the blocking is because the bootloader is open and Google detects this and blocks the device.

Am I assuming correctly?

The question is whether the bootloader can be locked, whether the manufacturer used the device’s test keys without encryption, as far as I know the bootloader can also be locked on other Dumbledroid devices, so if so, then one part of Google’s security test will pass successfully.

There is no hardware attestation on these devices. Will not pass without hacks, regardless of bootloader status.

I may be missing the boat but the new dumberos device will have NFC.

@ars18 whats with the tcl?

Nopes

Can you post your findings on the sonim xp39?

(And if you have time maybe another topic with modified partitions and guide)

Need someone to upload stock to make sure I didn’t make a mistake that time.

It’s in the repo

I forgot who but there are people on the forum if I remember correctly that have the phone. Not sure how they’ll pull it though. If anyone has it…

xp3900? i got one.
