It can't have 5.0.0. PRA-LX1 was released with 7.0. It is possibile to update the phone to 8.0 without wiping it, essentially by deselecting userdata partition while flashing the phone with EFT Pro and then this method will work. Keep in mind that EFT is very pick picky about drivers and it's recommended to use the one they suggest (there's a link on gsmhosting forum) or you may be stuck without a lockscreen and abiltiy to retry the process.

I can make a decrypted full filesystem dump of it, no matter if the user lock is known or not, the FRP is locked or not or the phone BL is locked or not!!!

Thank you @arcaine2.

With all due respect but accordingly to EFT this phone has  PRA-LX1C432B162 software version which indicates EMUI 5.

Have you ever practiced upgrading firmware or it’s just theory?

And one more question.

I assume you have experience with EFT so, I have pattern locked ANE-LX1 with “ANE-LX18.0.0.180(C432)”. To unlock EFT needs “UPDATE.APP firmware that matches device version & security”. But their FTP doesn’t offer exactly such a firmware. Which one would you use?

Best regards.

@bogus: I found another way around it, without the need to flash anything, forget EFT or other "promising", but mostly not working tools...

It's not such a huge sum, I don't publish it here, but I send you a PM.

@passcodeunlock that sounds brilliant though, we don't doubt your ability to do it, but maybe you give us a little briefing about the process.

Also, PM me with the cost.

I won't tell the details, but the method is a decrypting on-the-fly acquisition combined with a slow brute force. The slow bottleneck is the device itself.

I sent you a PM.

I guess we misunderstood each other. I assumed you're talking about Android 5, while it was released with Android 7. In the end, this firmware is Android 7, with EMUI 5.

I used it and it works for firmware update. Flashing Huawei devices is always risky and troublesome so that's the last option i would try.

I'd look elsewhere. Using different firmware as UPDATE.APP resulted in wiped phone for me once (it was a test device so no harm was done). Surprisingly, you can find a lot of Huawei firmware files for free here https://androidhost.ru/search.html

 

EFT itself can be very picky with the drivers. It's fairly easy to be stuck on device without a lockscreen after once of the patch if you don't get "adb auth" dialog beucase of the drivers.
