My Mate originally is L29C636 running on Nougat beta (I forgot the exact version)
Because I wanted to get Oreo, I downgrading to MM using rollback package, debrand to DL00 (Which I think unsuccessful) and then flash DL00 ROM. Along the way I think I mess up pretty badly. In MM TWRP I tried to flash Oreo ROM and it stuck halfway. I think the fastboot and EMUI dload got replaced during this process.
Now what is working are I can boot fastboot and it show my device is unlocked. eRecovery also can be accessed. EMUI dload can also be accessed. Don't have TWRP and no System/OS so can't boot up.
In fastboot I can't flash anything at all it seems. Oreo/Nougat/MM TWRP recovery, Nougat and MM system.img/userdata.img/cust.img/cache.img, all failed. I manage to get some info on my current brand:
With eRecovery, it always "Getting package info failed" message. I've tried changing my wifi DNS to 81.177.139.39 and also 188.225.84.142 but both same result. Maybe because my oeminfo all screw up?
In EMUI dload I tried using UPDATE.APP from L29C636's Nougat and MM, both fail. Oreo "DL00C17B828 (8.0.0.828) " and "DL00C17B839 (8.0.0.839)" also fail, but using HuaweiUpdateExtractor_0.9.9.5 when I tried to open UPDATE.APP content, it give
So I don't know is it Oreo ROM not compatible with HuaweiUpdateExtractor? But the file that come together in the zip "update_NXT-DL00_dualcu_cn.app" content can be viewed by HuaweiUpdateExtractor, thought when I try to fastboot flash CUST.img and USERDATA.img that I extracted from "update_NXT-DL00_dualcu_cn.app", it still getting FAILED message.
I'm really out of idea now whats more can I do. I already spend tens of hours trying different ways or combination and reading as many info to see if I missed out something. If anyone can give some suggestion what else should I try, I really appreciate it. :crying: :fingers-crossed:
