"Object reference not set to an instance of an object" (2.9.2) and/or "Bootloader locked" (3.0 Pre2)

EpicLPer commented 1 month ago

Description

I've been trying to get my Lumia 950 (RM-1104) back to stock to try out a newly released Android ROM. As a few days ago the official servers have been turned off I've downloaded (hopefully) the right FFU and emergency files and tried flashing those. I also found an old backup dump I made a few years back and tried to flash that, however the same error "Object reference not set to an instance of an object" comes up.

Using the new 3.0 Pre2 version shows "Bootloader locked", however I'm certain that's not the case as I already ran Windows 11 on this device, further the 3.0 version is constantly waiting for the device to be in Flash mode despite it already being in Flash mode. On 2.9.2 it does recognize the device in Flash mode, however it still throws the reference error.

Choosing "Flash original FFU" just freezes WPI, then closes it a few seconds later.

Steps To Reproduce

Connect device
Try flashing FFU, a backup or unlocking Bootloader
Either "Object reference not set to an instance of an object" error occurs or the tool crashes

Expected behavior

Functions should work as described :(

Heya, I fixed the issue meanwhile and it seemed to be device related. So the only logs I'd have are the ones still being left behind after all my tests, tho I guess they would be huge to share here. If there's anything specific I can share or a specific section that would help you can of course provide then :)

I had Windows 11 flashed on it before, somehow it was stuck in a somewhat "limbo state" of WPI telling me my bootloader is locked but it... wasn't? After using thor2 directly to flash a FFU for my device it flashed just fine, however was then stuck at a red flash recovery screen. WPI at that point picked it up again and suddenly the bootloader unlock steps started working :) After like 20 failed attempts from WPI to try and unlock it it threw an error that it couldn't do so, however at that point Windows Mobile started booting... I then set everything up, shut down my 950 and then tried the bootloader unlock again which now worked.

So yeah, I think my Lumia was just in a somewhat weird semi-bricked state which confused WPI, would be my guess.

gus33000 commented 1 month ago

@EpicLPer these log sections could be useful but only if i knew what version of the app they matched for, could you try to fetch this? thank you.

gus33000 commented 1 month ago

@Cheikhabbas44 this is a separate issue you are having and is also offtopic and not in english, i would advise you to file a separate issue properly on this repo. thank you.

Cheikhabbas44 commented 1 month ago

Hello, how are you? I have a problem on my Lumia 950. I can't unlock the bootloader please. Help me how to flash my phone thank you you see every time I tried to flash I try that is displayed

gus33000 commented 1 month ago

@EpicLPer Please try to gather logs with preview 3 (https://github.com/ReneLergner/WPinternals/releases/tag/3.0-preview3)

Delete the old log file before, we added a lot more debug logging in this preview update. This should enable narrowing down the issue

EpicLPer commented 1 month ago

I sadly cannot reproduce the issue anymore or test the new release as I've managed to flash my Lumia already, so it's essentially "back to stock" and then flashed with an Android ROM :( Whatever weird partition layout or other issues my Lumia had with WPInternals is therefore gone now.

gus33000 commented 1 month ago

Alright if you ever get the issue again please let us know via a new issue then, good to know it got solved on your side thank you!
