    Huawei Nova 3 PAR-LX9C636 Error writing Bootloader problem

    Hello I tried repairing a Huawei Nova 3(PAR-LX9C636) deadboot, black screen, but it's detected on fastboot and com ports. I saw my device compatible with dc-phoenix so I bought a DC-Phoenix + HCU License(3 days) for 19 EUR. I tried every bootloader versions of Hisilicon Kirin 970 and update it through testpoint and fastboot mode but it's stuck on 'Error Writing Bootloader' everytime. Also i get stuck at 'looking for device in upgrade mode' in fastboot mode. It seems hopeless to repair my nova 3 and I'm requesting a refund.

          Did you read that we do not work on weekends? License extended, use temp bootloader unlock on dc-phoenix, make sure battery is connected to device and charged if it's bricked and you are trying to repair it. Perform it in this order:

          1. Restart DC-Phoenix.
          2. Press CTRL+L
          3. Select service - Load and temp bootloader unlock
          4. After unsuccessful service error close DC-phoenix
          5. Open directory where DC-phoenix software is placed in
          6. Look for .dgtkl file there, send it to me, please

                This is the dgtkl file that the dc-phoenix generated. It is inside the zip file. I selected the bootloader Kirin970_T1_A8.0_V1.

                  Are you sure it's PAR- and not PRA- ? in such case you would be using wrong loader, need to use kirin655. Logs also show that loader does not match device. License extended once more.

                    Yes I'm sure it's PAR. I tried to use kirin655 bootloader just like you ask but I yield the same results. Btw here is the dgtkl file when I used kirin655 bootloader.

                      Just to clarify regarding my device, it is a Huawei Nova 3(PAR-LX9/PAR-L29) which is listed on the supported models.

                        Sadly as it seems loaders for your phone does not fit, really strange and unique problem that sadly can not be resolved.
                        Refund is available, but due to changes in policy by PayPal regarding refunds, taxes are applied. If you see no use in those remaining credits we can do a refund, but you should be aware that refunded amount will be less than you paid because of these changes. Or I can freeze license of your 3 day license that we can add back. Please let me know your decision.
