[OP7T T-MOBILE][OOS 11.0.1.5 HD63CB] Unbrick tool to restore your device to OxygenOS

[kjullian19]

Hi! This guide is great. I have an issue with the firehose file where I found the right firehose file from my device using firehose finder on GitHub. However, that file is in .bin format instead of .elf. How can I convert it, and is that safe?

After unbrick, I get no data, or phone calls, anyone know why? It's detecting my sim card, and phone number, but cant make calls or access internet through data. Wifi works

FAQ:

My device isn't detected when I click on "Enum" button

Go to device manager and make sure your phone shows up as QDLOADER 9008.
If it shows up as QHUSB_BULK, it means Qualcomm driver wasn't installed automatically by Windows Update. Download the latest one from Microsoft website at http://download.windowsupdate.com/c..._fba473728483260906ba044af3c063e309e6259d.cab (source https://www.catalog.update.microsoft.com/Search.aspx?q=qualcomm hs usb 9008 ) and install it manually by right clicking on QHUSB_BULK and selecting "Update driver software" and "Browse my computer for driver software" to where you downloaded CAB file.

MSM tool is stuck on "Param pre-processing"

Ensure you're using the Qualcomm drivers linked in first part of this FAQ.

What is SMT Download mode?

Just don't try to unlock that mode, it will wipe your IMEI and your Widevine certificate if you use it.
