Huawei Mate 7 (MT7-L09): "phone not found"

[JackMate7]

Hello
I try to obtain bootloader unlock code. I've followed tutorial and I've got 4 credits.
But everytime I try, I get "phone not found".
I've tried with "auto detect", with "mate 7", with "hisilcon kirin android", same result.
Is MT7-L09 (with Android 5.1.1) supported ?
Thanks

Have you followed detect instructions? Put phone into manufacturer mode? guide https://www.dc-unlocker.com/huawei-a...n-unlock-guide

[JackMate7]

Yes I'm in manufacturer mode.
Drivers are installed. I can see COM ports in device manager.

Ok, what happens when you try to detect it manually by selecting com port on software? If possible attach screenshot of your device manager modems/ports sections.

Looks like one of the beta firmwares of this phone, unlocking for them not available yet, this problem is being investigated. If you do not want to wait you should downgrade to one of the standard firmware and then do detect/unlock.

[JackMate7]

Ok, it works after downgrading to MT7-L09V100R001C00B137SP03

Thanks !

Great news, thank you for letting us know it.

I've a stupid question: if I upgrade now to MT7-L09C900B324, will the bootloader code change ?

Since this firmware is beta we can not guarantee, in general it shouldn't.

Hi,
I've the same problem. MT7-L09C900B324 is not beta! It's the official 5.1.1 firmware from Huawei. My phone was OTA updated to B331, which is also from Huawei.
Since I'm not happy with downgrading to B137, is there any plan to support B324/B331?
Thanks!
