[OnePlus 5 Questions & Answers] m0nss7erKill:
Hello! I got 128gb board from aliexpress to erplace my 64g, because the phone works pretty well, but I desperately needed space. (Because of about 40GB of music)

So the board came with H2OS, and android 5.1.1 if Im not mistaken.. Board works fine, but H2OS is useless for me. I wanted to install OOS or something coustom, like any android 12 for example.

I have all the drivers, unlocked bootleader, fastboot etc, bull****, phone is recognised in ADB and fastboot, even in EDL mode. But every time I try to flash ANYTHING, twrp, another stock ROM, the 1.8GB OTAs just nothing happens.

With the H2OS, i tried to flash something for about 10 hours. When I managed to soft brick my phone, I took it to the shop, and they installed OSS 5.

1st problem. Thats old AF. 2nd problem: Cant update Google Play services, which makes installing anything from google play impossible. Managed to install Vivaldi and AIMP player from apk, but still need tons of other APPs. I dont really want to leave my phone again, stay without a phone, got out off work etc.. Its kinda waste of time. (Not like im not wasting time trying to do it myself, but its not really the same)

So... Whatever BS I wrote above, what I did was:

Enabled USB debugging, OEM change, unlocked bootloader and critical bootloader or something like that.

Tried to flash different stock ROMs, many versions of TWRP. ADB Devices and Fastboot devices see my phone. I get the serial number after executing the command

I followed many different guides, after "Fastboot flash" "fastboot boot" and whatever the different guides used I just get plain nothing. Nothing happens but a frozen console. I tried to run it as administrator, navigate to the folder - always the same - nothing.

When I Soft bricked the phone, I installed some official ROM (the big ones 1,6-1,8GB) manually through the "system updates" menu in the phone. I got the OOS boot logo and I was stuck there (it was probably OOS 5)

Before I brought my phone to the shop, tried the MSM tool, that is supposed to pretty much bring your phone from the grave. disabled the driver siganture, installed drivers, phone shows as the Qualcomm BS, View attachment 5804463

So I try to start the process Aaaaand... Nothing. It got stuck at Param Prelaod for 6h and the tool said "Thats too long bro, not gonna happen"

And now because I have OOS I thought that I might be able to flash it through MSM to the latest OOS and have my stupid apps, and perfectly functioning phone. Nope. Its the same deal. Its just stuck at "Param Preload" (Took the photo after I disconnected the phone) View attachment 5804465

I was thinking about reinstalling my PC, and try again.

I tried these and many more files, zips, msm versions etc..

4 USB cables, USB 3, USB 2 ports, different charging ports for the phone.

Somewhere I saw a warning that if there are problems, you could try Intel based PC. I run Ryzen 5 1600., and I dont have any other PC to try with.

I always remove the Pin on my phone before I try anything.

Also, the only ROM/OTA that I was able to install was the one that bricked my phone. First I did it though the System Updates menu, then install adb, internal storage, etc.. I was abe to install this thing from anywhere, it was the only one that cooperated somehow.

Now I tried to install "OnePlus5Oxygen_23_OTA_069_all_2010292138_6700" from internal storage, it loaded it for a bit and then it just got back to the internal storage menu.

After that I tried the MSM (photo above)- nothing.

Phone works atm, not bricked yet.
