How to recover your device after flashing incorrect DDR xbl images

[semdoc]

No matter how you are experienced or skilled in flashing ROM's, the things sometimes just happens. And you are here now...

Even I was aware which DDR model was my device, yes.. I did it - flashed by mistake DDR4 xbl.img to my DDR5 noodlep.

Of'coz, I wasn't that happy when I achieved it. Many googling, many searches - nothing. The only option was to return to OnePlus for repair.

But; there is a way. The idea came from Tom Marshall ( @tdm ) - he said that I can try to force "deep flash method" using EDL CABLE.

How to recover ? It's really simple.

Pre-requisites:

1. Windows 7 - 10 based PC (for msmtool) with properly installed 9008 COM port drivers.
Follow this guide to set and prepare: [OP8PRO][OOS 11AA/BA/DA] Unbrick tool to restore your device to OxygenOS


2. Buy EDL cable. it looks like that:

Now to revive your toy !

1. Start msmtool, click others (as it's recommended for msmtool), choose region of your device. Get ready to start flashing.
You'll see that the line with COM port says it's not connected (yet)
2. Connect the cable to your device - but not to PC yet.
3. Press the button on the cable - It's called "deep flash" button...
4. While you are still pressing the button, connect the other side of the cable to your PC (where msmtool is opened and ready to go).
5. Release the button and you'll hear that your device is connected. Check the line with COM port and you'll see it's connected.
EDL port will be opened for about 10 seconds. so you must be ready to start the installation.
6. Start the msmtool and wait till the finish.
7. The rest is well known msmtool flashing way.


Enjoy !!!

Haha, thanks for the confirmation, everyone said that the ram is fried and you have to change mobo, i said that there is no proof of that, and i was right.
Btw could you share link to where you got that cable?

Okay first off Qualcomm has multiple things in their source code that tell you you can ram flash your phone back secondly software can't fry hardware

Thank you @semdoc for the suggestion

Because I used similar like semdoc attached image deep flash cable and followed the steps, its seems to be not work. (no new notification in Device Manager)

1. @jef_00 do you mind share what type of deep flash cable/ shopping link?
2. After wrongly flashed XBL, is that normal the phone will be hot?
   (I have just unplug the battery so it won't over heat mobo)

 

[jef_00]

1. I used a hydra EDL v2 cable i get mine from AliExpress

2. Not noticed that

Hi everyone, I might need some help here...I have a OnePlus 8T EU model and I too have flashed the wrong xbl.img (DDR5 instead of DDR4X in my case). Reading this post gave me some hope and I bought an EDL cable, looking just as the one in the picture OP posted.

My phone has never been in EDL mode before, therefore it is not showing up at all in device manager, no QHUSB_BULK, no anything. It is therefore impossibile for me to try and install the drivers by updating the device entry there, as specified in the guide.

I tried to install the drivers in several other ways, using an installer executable or manually installing the .inf files, but the outcome is always the same: after following all the steps given, MSM, as well as Device manager, do not read my device.

What can I possibly try differently here?

İssues are with your Windows and quallcom drivers probably... I remember I had to switch to safemod in order to installl quallcom drivers.

I'm facing the same issue. Flashed ddr5 firmware instead of ddr4. The phone is completely hard bricked and is not showing on device manager as well.

Will the edl cable enable the connectivity so that i can do MSM?

Ordered youkiloon hydra v2 edl cable and planning to test tomorrow.
