Hi man, 2 months I patched the demo firmware version of these huawei, but these have the B120 firmware I do not know if it works in your B100, if you want to try I send you a perfect guide to make your huawei complete, it's a bit complicated but I think you can succeed, add me on Facebook: "Evolazio DePianetis - Fourth Evolved Humans System" direct FB Link: http://bit.ly/2EwZvty and I'll explain everything you need to do. PS: I already have all the files ready for the patch to get you downloaded, the only problem is that if it does not work on your B100, it stays stuck on the BootLoader, until I can not find a working solution for your firmware (for this reason I have not released any guide around the web and because I do not know how many huawei P8 Lite 2017 demo firmware versions there are around the planet).
I had a similar problem,.the fix for me was to debrand my phone and change it from pra-al00 to pra-lx1, now it works fully. You can find a lot of posts about this in this thread.

Are not branded are only demo firmware and are already PRA-LX1, what you say you can not do, you need a patched firmware that I have already done for these B120.
So, is there any fix for this yet?

Hi,
The only way to have custom rom is by rebranding to chinese firmware using Tecalote's HWOTA7 (you find it in the modding thread). Then, you will be on EMUI 8, and then you can flash Openkirin's roms (you find them in their website: openkirin.net).
Hope I've helped you.
Thanks guys.. but got problem how to get bootloader unlocked code.. can somebody point me the latest way to get the code..
unlocked code
use dc unlocker in playstore,work for me on VIE-AL10 and now change to VIE L29

Best way to get upgrade from EMUI 8 to EMUI 9

Good evening all,
I am currently running a P20 Pro (CLT-L09 8.1.0.159(C782)) with Stock EMUI 8 firmware, TWRP recovery and Magisk root.
I am looking for the best way to upgrade to Android Pie (EMUI9).
where do I begin, the huawei app is obviously showing no updates as I am in the UK and apparently a second class citizen!
I have tried the funky huawei method and unfortunately the update fails.
what other method can I use to get to v9 (primarily so I can jump to a custom rom like Lineage
thanks in advance,
Dan.
ps. if I have missed any important info please shout.

I think it's impossible. I'm in the same step. I downgraded from Official Hisuite to EMUI 11 and then downgraded again from HisuiteProxy to EMUI 10, but it was .178 which don't work with LZplay. So I need to go back to an older version of MIUI 10. We have to update to MIUI 11 and then downgrade to EMUI 10 with dload method, but the problem is that we can't use older versions because they don't allow us to install the firmware due to a ERROR message at the moment of checking the formware version. I suppose the problem is that we are on EMUI 11 (11.0.0.151) and we have to downgrade to an older MIUI 11 version to be able to downgrade through dload.

Hey waldoud, there are many threads on the internet about how to relock the bootloader . If you face network problems try reset to factory settings
If not try the indian rom.
