recovery mode – Unable to unlock the bootloader on the Mediatech tablet

I have a tablet that someone gave me to repair. It's just a generic Chinese mediatek tablet. It is stuck forever at startup. The Android logo appears and then stays in the animation forever. I've opened the recovery console and played with the available options. I reset it to the factory and cleared the user cache. adb will not see it with adb devices. Even if I go into the recovery console and click on the option "sideload from adb", adb refuses to see it. I can make the device boot into fastboot and fastboot can see it, but the problem is that the bootloader is not unlocked and every time I do a fastboot oem, that I select yes on the tablet, it fails for some reason. then restart in fastboot. When I try to start or write an img from fastboot, it does not allow me to write to boot or recovery partitions. I'd like to know if there is a devious way to janky to unlock the bootloader so that I can boot my recovery image or some sort of nuclear option that will allow me to reformat and rewrite the partitions. I do not know if this will help or not, but the processor claims to be a mt6580 and the motherboard has a number that lists it as kt961C12_80_216_v3.0. I looked into the problem and I successfully found a recovery image of the random Taiwanese company that created it. Therefore, if I can get it to allow me to start it, I can get the device unlocked.

Unable to refund on Magento 2.1.4

We used to refund orders via "Invoice" then "Have" all the time on Magento. However, the option has stopped working and every time we try to repay, it indicates that there has been an error and that the refund can not be processed.

We use as a means of payment and we have not changed anything to Magento or that could have caused this problem.

I am currently paying manually via, but since this leaves nothing on Magento indicating that the refund has occurred, it is causing all kinds of data problems.

Has anyone gone through the same problem and been able to find the solution?

Unable to position custom data labels in the center of Google Sheets cascading chart

The context

I've created a cascading chart stacked in Google Sheets, with custom data tags (guided by Ben Collin's tutorial on custom data labels).

My goal is to place the custom data label at the center of each segment of the stack.

When using the Value label type, the labels are positioned correctly using Center (Example 1 below).


When I change the type of custom label, the positioning becomes non-centered (example 2 below).

I have tested the following behavior when using custom labels:

  • The problem persists when selecting other types of items. The Center option is not unique
  • The problem persists when all segment values ​​are positive (see Example 3 below).


Is this a known problem with custom data labels? Are there any known fixes / workarounds?

Or should I use the addition of manually positioned text boxes on segments of the stack for custom, centered data labels?

Example 1 – Value tags & # 39; Are correctly positioned in the center
Value labels placed in the center

Example 2 – "Custom" labels are incorrectly positioned

Improperly positioned custom labels

Example 3 – The problem persists when all segment values ​​are positive. The custom labels below are not centered.
Example 3 - all positive values

Unable to change the MySQL port in Ubuntu 18.04

I have been trying for hours, and I can not find the problem.

vim /etc/mysql/my.cnf


!includedir /etc/mysql/conf.d/ 
!includedir /etc/mysql/mysql.conf.d/



And the following file:

vim /etc/mysql/mysql.conf.d/mysqld.cnf


socket          = /var/run/mysqld/mysqld.sock
nice            = 0

# * Basic Settings
user            = mysql
pid-file        = /var/run/mysqld/
socket          = /var/run/mysqld/mysqld.sock
port            = 3444
basedir         = /usr
datadir         = /var/lib/mysql
tmpdir          = /tmp
lc-messages-dir = /usr/share/mysql
# bind-address           =

Then I do a reboot:

systemctl restart mysql.service

But in the mysql console, I still see it. Even in systemctl status mysql

mysql> show variables like '%port%';

javascript – Unable to validate an email – MAGENTO api – comment

I tried unsuccessfully to validate the email of my website with MAGENTO's client API and send a message (exists or does not exist)

I mean, I have a website where customers are created; an e-mail is sent to each client (the e-mail is the primary key of each client in MAGENTO) and every time the client is created on my site, it is also created in MAGENTO (with a middleware) . The problem is that sometimes when a new client is created on my website when it tries to create the client in MAGENTO, an error message is displayed: the customer email already exists so I want to validate if the email does or does not exist in MAGENTO.

A few years ago, I wrote this code and it validates whether the e-mail exists or not. but it does not use a MAGENTO API



Email validator

This is my MAGENTO API, take a look at this:


Here is an example of the JSON code I received from MAGENTO when I clicked "SEND" on POSTMAN:

        "magento_id": "54678",
        "firstname": "Richard",
        "lastname": "Herther",
        "email": "",
        "password": null,
        "website_id": "8",
        "group_id": "7",
        "disable_auto_group_change": "0",
        "prefix": null,
        "middlename": null,
        "suffix": null,
        "taxvat": null,
        "account_id": (
        "document": "66958746845",
        "document_type": "15",
        "gender": null,
        "telephone": null

This is a brief explanation:


Could you please help me solve this problem? I need to change my code a little bit to use MAGENTO's API but I do not know how to do it.

Can you help me?

kali linux – Unable to connect to inverted shell – connection waits indefinitely

I've installed a simple Kali Linux machine on AWS and added a security group where all the ports are open and then I ran:

nc -vlp 4444

Now, on my own computer, I run a simple Go program:

package main

import (

const IP = "MY_PUBLIC_IP:4444"

func main() {
    conn, _ := net.Dial("tcp", IP)

Nothing really happens, the connection waits until the time expires. Am I missing a configuration?

Thank you.
