recovery the bricked phone, but how can I upgrade to android 9?

[2anyone]

just use MsmDownloadTool V4.0.exe to recovery my op5 to oos, but the version is quite low as Android 7.1.1.

checked the system update, it told me up to date. which is of course not true.

tried to clean the cache of google framework service and oneplus framework service, still nothing in updating.

tried installed oxygen updater, and download 3 update zip from 7.1.4, 8, last version of 8, but each time I use local install in system uploading, then reboot to recovery, it shows me "failed". none of version works.

I even tried to install in recovery, wipe cache and data or just wipe data, then install from internal disk, none of the file works, even don't have any popup fail notice, just go back to file chooser interface.

I can still go back to system by switch off and on again.

How can I upgrade the old version of android in my oneplus 5?





original:

used use lineages os with Twrp, and I would like to flash to original oxygen.

download full rom zip in https://www.oneplus.com/uk/support/softwareupgrade/details?code=PM1574156143164
copied to phone disk
went to twrp
wipe Dalvik, System, Data, and Cache
then tried to install the full rom zip, but met "no Digest File found" error
found it must be twrp old, so I download new one in https://dl.twrp.me/cheeseburger_dumpling/twrp-3.4.0-0-cheeseburger_dumpling.img.html
copy to phone and flash it to recovery.
select "reboot to recovery"
then problem coming: I can only see the oneplus logo with powered by Android. it won't go any further.

I am not sure any thing wrong during my processing, but maybe 2 things:
1, I wiped the system
2, I didn't clean the screen lock pin before I flash

so, my question here is, if possible I can flash the original oxygen os in this situation?

if positive, could you please give me a step by step instruction?
by the way, the zip rom I download from oneplus site isn't have the "flash-all" script.

please please help me .

First install OxygenOS 5.1.4 based on Android Oreo and boot to that version to create /vendor partition for Treble support

Please help. I bought a phone with Beta installed. I wanted to switch to the original system. So I screwed up something so using the MsmDownloadTool tool I wanted to use it by uploading everything from scratch. I fell into the Chinese H2Os system. I searched again and I already have the original ColorOS based on Android 9. But I can't update it to 10. What do I have to do? Oh .... the bootloader is unlocked ...

Use an EDL Flasher (unbrick tool) here on XDA

thanks for replying

I had figure out my problem.

it seems the rom I flashed using MsmDownloadTool had something wrong,
I've changed another one, it shows me the update from the first start after flashing.

if you are directly flash to coloros android 9 from lower version other than android 8, it might be the problem you won't got the update in the system. It might be have issue in wifi or gps as well, which I bet you didn't well test yet.

that's all about the system partitions messed up. regarding my understanding.

solution is simple, but time consuming:

you have to flash an original rom using msmdownloadtool, make sure that rom will have update notification in the system menu of settings. then upgrade from there one level up each time, till to the android 10. (chinese version do have 10 available)

than, you can download oxygen os android 10 to flash on the coloros android 10 (hydrogen os android 10) you just done the upgrade, don't forget wipe data/cache before flashing.

hope that's helps.
