After flashing the Honor 9 Mobile Customized Edition, why do there still freeze, flashback, black sc

Hello, it is recommended that you try a factory reset.

If the problem persists, we recommend that you bring the purchase invoice to the local Huawei after-sales service center for inspection and repair.

2. You can also have an after-sales outlet query address entrance at the bottom of the official website page of Huawei**;

If the service outlets are far away, you can choose to send repair services.

Mobile phone black screen, splash screen, flower screen, white screen, recommended:

1.Click the back button to see if you can exit the software. If you can, exit and re-enter.

2.If you can't quit the software, it is recommended to restart the machine and try: press and hold the power button and the down volume button at the same time for more than 7 seconds to restart the device;

4.If it comes with system software, it is recommended to update the system version of the mobile phone to try: please go to Settings - About the phone (about the device) - Software update (system update) - Update (please back up the data in the device before upgrading).

If the problem persists, it is recommended to bring the purchase invoice, repair card and mobile phone to the local mobile phone purchase office for repair or spend money nearby to repair it.

The glorious machines are all locked, and I can brush them.

Definitely not, because the signal frequency and band of different cards are different, and it has nothing to do with flashing.

Hi! Dear, may I ask what version of your Mi 3 customized machine?

It is risky to root your phone and then force it to upgrade, especially if the recovery mode is also modified. The forced upgrade may not be restored, so it is recommended to go to the service branch to solve the problem. If you do not have a rooted phone, it is recommended to bring the purchase invoice to Huawei for after-sales maintenance, and if you cannot back up the data, you can consult the maintenance personnel.

It is not recommended to flash your phone.

1. After flashing, the mobile phone may not be able to reach the best working state, and some functions may not operate normally. At the same time, because the third-party firmware is not fully tested, there may be problems such as poor compatibility and system susceptibility to virus intrusion.

2. The brushing machine will bring unpredictable negative effects, so you must be cautious. If the device cannot be used properly and cannot be restored, you do so at your own risk.

3. For software and hardware failures caused by flashing, Huawei's after-sales maintenance outlets can charge for ordinary out-of-warranty software maintenance.
