unbricking – Huawei P9 lite enter bootloader without volume keys and system access / recovery

About the phone: Huawei P9 lite VNS-L21C432B161 (Central Europe)

First modifications
A long time ago, I unlocked the boot loader and managed to root the phone. I've disabled the OEM unlock option in the settings after rooting because someone said I had to do it for security reasons. Then came EMUI 5 OTA. It is somehow updated without me accepting it. Android nougat detected that the bootloader was unlocked and so it assumed that the OEM unlock option was also turned on while it was really not, which made me prevented from reactivating it.
I've used the https://forum.xda-developers.com/huawei-p9lite/how-to/tutorial-rollback-n-to-mm-c432-devices-t3563955432-devices-t3563955 "<- Official restore package and installed ROM stock by Dload.

This is the part where I planted myself horribly
Now, I wanted to update Android 7 again, but Updater did not give it to me and I could not get it through TWRP. I've reinstalled the cancel package in download mode because it allows to add any ROM, hoping to then install Android 7 in download mode. ROM.

Current situation
Now I'm stuck on the "Your device has been unlocked and can not be trusted anymore. TWRP 3.0.1 must be installed but it never starts. Unable to access the boot loader, the phone does not seem to detect the power + volume reduction combination. Recovery remains stuck on the shortest warning screen at startup, recovery is also clogged. It was like that even before I tried, I do not know what caused it. I can not even access the download mode, which remains stuck also on the screen shorter warning.

Objective: to get to the boot loader without using the volume keys (this just does not work for any reason) and without going into system / recovery / erecovery because they also broke.

Thanks in advance

ram – why can not I move the files from the internal storage to the SD card on the Huawei P9?

I'm using EMUI 5.0.3 with Huawei P9.
I can not find any of the recommended menu steps above.
They simply do not exist. So it seems that I can not move files or application data on the SD card.
It seems that Huawei wants users to buy a new phone every time the internal memory is full (or that the battery no longer works) !!?

How to make WiFi measured on Huawei with Android 9 Pie?

I want to set a Wi-Fi network (mobile access point) measured on a Huawei phone equipped with Android 9 – so that it is treated as if you were using data from a network mobile.

I've been looking for ways to do that. Generally, Android 9 supports this mode by clicking on the WiFi name and then selecting Advanced. But on the Huawei P20, there does not seem to be any advanced option. Has Huawei changed the Android stock for this option to disappear?

huawei – Bluetooth continues to turn off and disconnect in the car when the charging cable is not connected

I can connect my phone via Bluetooth to the car without any problem. But every 2 to 10 minutes, it disconnects and deactivates Bluetooth on my phone and, after about 1 minute, is automatically activated and reconnects.

This only happens if I do not charge the phone. So, I think it has to do with the optimization of the battery. But I can not find any Bluetooth application or settings to change something like this.

The same problem occurs in Ford, BMW and Mini.

rooting – best opensource Android for Huawei MediaPad M5

This question already has an answer here:

I have a Haewei Mediapad M5 tablet (model BAH2-W19). Android 8.0.0 with a Logitech Bluetooth Keyboard

I am a 60 year old Linux guru (using Linux since 1993, Unix since 1987, coding Bismon, holding a PhD in computer science since 1990, etc.) and all five home computers use a Linux distribution (often Debian) or Ubuntu). I have contributed to GCC (its plug-in system) and compiled many Linux kernels (for all the PCs that I had since the previous century).

I want to root my tablet and install an Android opensource on it. I do not care about losing all the data, but I do not want to make up my tablet.

What are the concrete steps?

file management – pyRenamer does not rename some Huawei P20 images

j & # 39; uses pyrenamer for many years without problems. Now I have some pictures of the camera Huawei P20 and pyRenamer do not rename approx. 10% of the images. Instead of the date and time, I am stressed instead. The name change model that I've been using for many years is as follows:

`{imageyear}-{imagemonth}-{imageday}_{imagetime}_{rand1000-9999,4}_{cameramaker}_{cameramodel}.JPG`

After some research, I discovered that

  • about. 90% of all images have no description. pyRenamer works well with these files (left side of screen capture)

  • about. 10% of all images have a description (to the right of the screenshot). All files seem to have a hexadecimal description.

enter the description of the image here

I guess the description tag is the reason why pyRenamer does not work. Any ideas for which Huawei adds a hexadecimal description tag to some images? Now, how can I remove the image description tag? Bash orders are welcome.

AppData backup on Huawei P7 Lite without root

Hi, I'm looking for a way to make an appData backup on

Device: Huawei P7 Lite (2017)
ROM: Emui 5.0.3, Android 7

So, for example, appData from applications:

  • Remarks
  • Chromium
  • Brave Navigator

The TitaniumBackup method needs the root, and the root implies 'erasing the data', so I need an alternative method.

It's a failure, an Android / ROM-side error that is causing so many problems with user backup, local policies and methods.

The phone is encrypted and the user password enabled, I am the owner, so the data is accessible, but I can delete it if it is problematic to perform backups.

I had never phoned the root of the phone because the official updates of the warranty and Ota.

security – Why do more than 300 Huawei robots explore my forum?

Since a few days, I have noticed a huge increase in the traffic on my forum by the invited users. All use the same range of IP addresses that goes back to China, Huawei being more specific.

Is there any indication of why this is happening and, from a security point of view, should I preemptively disallow the entire range of IP addresses?
