Everything seems to be running smooth, except for an error which pops up on after restart/shutdown. The message reads " this build is not for end user" once you get pass the error message, everything else is smooth and normal.
My question to you is, if the error is expected and if i can still avail official OTA from LG or should I have to roll back to Lollypop manually and then upgrade?

As per the news LG is rolling out official marshmallow to users only through LG Bridge only not OTA update.
The question to your answer will be revealed once you recieve official marshmallow to your device on LG Bridge.
But if marshmallow is officially released in your place and when you sync the device with LG Bridge if you get it is up to date then you have to download your official .KDZ file of your device and flash as you did now.No need to roll back Lollipop again...

Lg G5 H850 sucessfully changed region and firmware on stock non rooted

Hello. Great news from me ?
I sucessfully changed my ISR firmware to EU firmware. And guess what, no cust error on boot. Yeahh
Its like this:
Just download latest 20p firmware and flash it via lgup 1.14 and uppercut. First set lgup to refurbish and click start. Phone will go to download mode and start flashing. It will give known error *kdz not supporting refurbish* and stop on 4%. Do not exit from download mode on phone. Reopen uppercut and flash 20p firmware in upgrade mode and wait.
After flashing make factory reset phone and voila U have 20p firmware without cust error message
I used this firmware
H85020p_00_EEO_GB_OP_0916.kdz
Happy flashing ?

Pics or screenshots would be appreciated ! Don't get me wrong ! No one wants to brick their phone

It is for H850 eu model. Read for differences between models. If there is no difference, flashing will work. I dont know specs for Canadian model sorry

oh,and one more thing, it starts with new carrier apps from Orange (France) i bought i phone from there, i have no idea,i can't even root my phone cause of <waiting for any device> issue in adb fastboot

have changed my fw from 20k open EU to 20 p EEE for GB now. (but device was rooted!) No problems until now.
security level (as expected) Sep. 01/2017
Edit:
Ok, i have found my fault.To use 20p, it was necessary for me to backup cust folder from 20k at first and then to restore him to 20p!
Now i have no problems with BT and my secure level is 9.2017

Hi,
I've got H850 with v20c-ISR-XX firmware, I want to try your guide...
I'm in France, wich .kdz do you suggest for me ? H85020p_00_EEO_GB_OP_0916.kdz is good for me ?
Can you unlock your bootloader now with a EU rom ?
Regards.

i recommand to update your whole cust folder with all other folders in it at first before updating to 20p!!
You should restore cust folder from 20c ( or your old version!) after backup!
And of curse edit your cust_path_mapping.cfg to your country code ( for me it was ffffffff,11 )
you will find your code entering *#546368#*850#
without this steps, i had many problems with system stability and BT!!!

No way. How to backup cust folder or edit it when our isr g5 is not rootable. We cant unlock bootloader. I'm using 20p firmware after flash from 20c and apsolutely no problems at all. Cust folder is market depending for provider apps, network settings or similar. Firmware is same for all g5 h850 and hardware also.
Cheers

@jaskooo
if you think, it is working alright, ok.....
the main thing is, that you are fully satisfied now!

Thanks to fahad. I have lg g5 h820 oreo firmware but i m unable to update it using lg up tool 1.4 version ... As it does not detect my model ... While in pc ports it shows lg com port 3 etc ....
Now tell me how can i update ...

Kindly first try and then tell me method thank you

I did not try to update it yet. What I tried to take it, is to connect it in MTP mode of file transfer, and run uppercut directly and read it there (when you run uppercut opens LGUP where I take the device). Hope this can help you!

I need someone expert who experiment on his device bcoz i m not an expert and in case of any problem i cannot unbrick my device .. So need some people review first ....
