i have p9 EVA-LO9C432B182
it possible to change oeminfo to EVA-L19C185
and install firmware EVA-L19C185B210
you should rebrand it to C185 first with a proper cust zip to flash.
Last week I tried to de-brand from C34 to C636. No matter what I did, I always ended up with the C900 firmware.
Managed to flash back to C34 and in the process flashed the "optus/au" AND "hw/normal" folders to /CUST/
The result was a successful flash back to C34, build number reading correctly, Optus branding on startup and everything sorted. But I'm still trying to get to the bottom of how this all works.
What I noticed last night is that the Project Menu is now usable (*#*#2846579#*#*) previously blocked by the Optus build. On further inspection, I am also missing 'custom.bin' that by my understanding tells the phone where to look for build-specific files on the CUST partition.
Questions:
1. Without custom.bin - how does the phone know which folders to access in CUST?
2. If I were to add a custom.bin that directed to the /hw/normal folder on CUST, how will this affect my Optus firmware.
3. Still trying to work out why the de-brand didn't work to C636 and my best guess is that the oeminfo I flashed didn't match the exact build of the firmware OR I didn't flash it right- can anyone confirm how specific oeminfo is to the firmware version?
Any help is appreciated. Just trying to learn.
Thanks.

Where did you get the C636 oeminfo and custom.bin from?

oeminfo from this post.
Custom.bin I copied from the SKR tool files. Technically the C636 files on the SKR tool are for the dual sim variant - so I can't use the oeminfo, but the actual contents of custom.bin are a single file path, so it shouldn't matter.

I see, I did something similar but ultimately I just went to C432 and now I am rather happy I did change it to C432. I am getting updates much sooner and I have no issues at all with this firmware.
Also, when I backed up my oeminfo and custom.bin using the SRK and then restoring it, this broke my P9, so I dont trust the backup feature of the SRK tool.
How would you add a custom.bin manually? I've bricked my phone, but I have the backed up oeminfo and custom.bin and root access via the terminal in twrp. I found out where to flash the oeminfo but not the custom.bin. Thanks in advance!

Did You found solution?
Hello guys,
I've a question here: I installed nougat some time ago and untill yesterday I had the necessity to rollback my eva l09 to android mm. I installed the first update and so my p9 moved at the c900 cust. After I found that p9 firmware I downloaded was not correct for my phone and I discovered that not official eva l09 firmwares have been released till now. So now I have my p9 whit c900 cust where the original one was c432. Is it possible to restore my default cust without losing warranty?
Thanks

Hello!
I was on c185b361 but I wanted to change the cust to c432 ( for faster updates and atari's root ) so I opened bootloader installed twrp then I removed the system then I installed c432b161 but the cust changed to c900, I looked for an oeminfo but I didn't find one for l19, so can you tell me what to do? ( right now I'm on c900b182 )
