Symbian smartphones have hidden disk Z :. It is not displayed in the built-in file manager, but it can be seen using third-party programs (FExplorer, X-Plore and Y-Browser). The user can freely view the entire tree of folders on this disk, view any files, but you cannot delete any of them or change its content. This is due to the fact that the Z: drive is designed to store the phone's firmware, and write protection was introduced specifically so that the virus could not completely disable the device.
If the file is located on a disk that is not write-protected, but you still cannot delete it, first check its attributes. Use a file manager for this third party developer... Select the menu item corresponding to the mode of changing the attributes (the location of this item depends on the version of the program) and do inactive attribute Read only.

If it does not help either, check the position of the write-protect switch on the card itself (if any). Finally, the card can force itself into Read only mode in order to prevent data loss if it is badly worn out. Then immediately do backup card and format it. If the situation repeats, replace the card with another.

Today, you will not surprise anyone with a smartphone with the capabilities of a computer. Powerful and "heavy" graphic games, movies in HD quality, VoIP telephony via GPRS and Wi-Fi ... top models mobile devices... The design of the phone is gradually becoming more complicated, there are special firmware that are responsible for effective work the entire device. The problem is that when such a firmware flies, the phone turns into a "brick".
Operational, display, flash memory, processor, accelerator. This is not a listing of the working parts of a computer. It is these details that make up the modern, in fact, standing on the ladder of technical progress much closer to full computer than just a phone. It should be noted that it is flash memory that is very important for modern telephone set, it is a chip in which hardware settings and software are imprinted in a special way. Popularly, these settings are called firmware, and the software update is, respectively, flashing.
The device freezes, shutdown, spontaneous reboot Disabling Bluetooth or Wi-Fi ports are some of the most common symptoms of impending firmware issues that need your attention. By themselves, these problems will not go away, on the contrary, they will only increase. It is very rare when it flies just like that, without warning. The reasons may vary. A new, just released device may have a so-called "raw" firmware, which the manufacturer is going to refine in the future. The smartphone can also break down as a result of the actions of its owner, for example, due to the installation of custom firmware that was collected by users on the basis of the factory and are in pure form experimental.
A smartphone with a flashed firmware can be referred to a specialist service. Moreover, it is better to do this if the device is still under warranty. For those who have guarantee period ended, there is an opportunity to cope with the problem on your own. I must say that manufacturers have different attitudes towards self-repair their products. Let's say Sony ericsson and until recently Nokia even encouraged experiments on, posted new firmware directly on the official website, provided users with special software for communication between a smartphone and a computer. And HTC and Apple blocked access to the system files of their phones, forbidding users to change their structure.
To make a phone yourself, look on the Internet for sites and forums of fans of your brand of phone. Usually these sites have experienced people who will always help a newbie.
To restore the firmware, you will need a USB cable, version software, downloaded from the official website of the manufacturer and a special program that allows you to replace the old software with a new one. Pay attention to the fact that when replacing the firmware, all data on internal memory phone will be erased, including notebook, photos and other media content. Data on external map memory, if there is one in yours, will remain safe and sound.
Firmware recovery may take a long time. Follow the manufacturer's directions for your brand of phone, take your time and don't be afraid to make a mistake. After all, you will not be able to "kill" the phone by flashing it. But the unfinished process of flashing can easily send you to the service, turning your smartphone into a "brick". To prevent this from happening, it is enough to provide the phone uninterrupted power supply from the mains.

The second reason could be an attempt to delete a file of a running program. Finally, the file to be deleted may be a virus file that has anti-deletion mechanisms. If you need to delete or replace an operating system file, the easiest way to do this is to boot from a second OS - if it is installed on your computer. If it is not there, you can boot using the boot Live disk CD. This is a shortened but fully functional version of the operating system. It is useful in very many cases - for example, when it is impossible to boot a computer from the main OS. With its help, you can and delete the file of your main operating system.

For example, when you delete a file, you can get a system failure under the "sauce" that it is protected from records, cannot be moved and so on.

If the prohibition is programmatic, it can be removed or bypassed.
Some time ago, our site talked about the one running under the Android OS. You probably remember that you can do this. different ways depending on the firmware. The same goes for deleting a folder.
For example, take stock Android 4.4.4. To delete a folder on this version of the operating system, you must click on the folder and, while holding your finger, pull up to the word "Delete" (on some versions, the trashcan is shown instead of the word "Delete").
After that, the folder will be removed from the desktop, but the applications themselves will not be removed. Most modern launchers and firmwares are configured in the same way.
On some firmware, it is impossible to delete folders in a similar way. These include Flyme from Meizu or MIUI from Xiaomi. On these firmwares, by default, applications are removed directly from the desktop, similar to iOS. And so that the user does not delete anything superfluous, folders cannot be deleted, they can only be disbanded. This means that you just need to remove all applications from the folder to the desktop, and when there is one application left in it, the folder itself will disappear, leaving behind the icon of the last application.
In the next screenshot, you can see that the folder cannot be deleted, it can only be moved.
The above does not apply to all firmwares. So, for example, on Samsung Galaxy even if you delete all applications from the folder, the latter does not disappear anywhere. However, it can be removed along with the application icons.
In general, friends, try it. If you did not succeed in deleting a folder from the desktop in one way, try another and everything will work out.
