Motorola devices are flashed with the RSD Lite program. The process is the same, but depending on the model, adjustments are made in the process. Let's take a closer look at this in the process of flashing the Razr M XT907 smartphone.
RSD Lite is Motorola's tool for installing software, downloading only official firmware and is not suitable for third-party modifications. The program checks the region of the device and will not allow you to install European or Asian firmware on an American smartphone, and vice versa. In addition, in most cases, it is impossible to downgrade the firmware version or certain partitions (except for an unlocked bootloader).
Specify the model of the device, guided by the information in the "About phone" section in the settings. This will help you select the correct file and avoid problems in the process.
Decide what type of firmware you need. The end of the file name contains combinations of CFC and 1FF, they do not differ in their structure, with the exception of the firmware file.
CFC - when flashing, all information from the phone is erased (flashes from scratch).
1FF - intended for updating and does not affect internal memory data
Download the firmware, but first, make sure that the disk space on your computer is at least 2 times more than the firmware itself weighs.
Download and install the drivers from the official page of Motorola, as well as the RSD Lite program from the link. Be sure to download the latest version of the driver and software.
Important! For security purposes, RSD will prevent the installation of inappropriate firmware, but exceptions occur that can damage the smartphone. As you should, prepare yourself and do not take hasty action.
Must Read:
For safety reasons, remove the SIM and MicroSD card, and make a backup of the data from the internal memory.
Make sure the battery is at least 75% charged.
Unpack the firmware you downloaded if it is in the archive.
The extracted folder contains an XML file, open it with WordPad or Notepad. In the code that appears, remove the lines, this will avoid software damage to the device:
<step operation="flash" partition="tz" filename="tz.mbn" MD5="… » />
<step operation="flash" partition="partition" filename="gpt.bin" MD5="…" />
Search by keywords - tz and gpt.
Also, if you have a device from the American operator Verizon, deleting the line <step operation="getvar" var="max-download-size" /> will solve a possible error during flashing. If there is no line, follow the instructions below.
Important! Installation of official Motorola firmware is the same for all models. In some cases, pre-editing of the XML file is required, and in others, it is not. The manual describes an example of upgrading Motorola Razr M XT907 firmware from Android 4.1.2 to Android 4.4.2. This does not require an unlocked boot, but to downgrade, for example from Android 4.4.2 to Android 4.1.2, an unlocked bootloader is required. Then we delete the following lines from the XML firmware of Android 4.1.2:
<step operation="getvar" var="max-download-size" />
<step operation="oem" var="fb_mode_set" />
<step operation="flash" partition="partition" filename="gpt_main0.bin" MD5="... />
<step operation="flash" partition="tz" filename="tz.mbn" MD5="…." />
Whether and what lines of code you need to remove for your model, check on the specialized forums.
5. Do a factory reset or delete the cache and date in recovery mode. To get into recovery (recovery mode), turn off the device, simultaneously hold down the power and volume buttons, and hold until the logo with text appears at the top of the screen. We find the desired item by scrolling down with the volume button (cyclic scrolling), the choice is made with the up key. In a new window (with a lying green robot), we simultaneously hold down both volume keys. In the list of actions that appears, clear the cache and data.
6. We transfer the smartphone to the firmware mode via RSD Lite, for devices before 2013 we do it manually, in other cases RSD will do it itself. The sequence of actions is the same as in the previous paragraph, only you need to select AP Fastboot.
1. Connect the USB cable to the connector on the back of the computer, do not use a USB hub or extension cables, use only the original cable or a high-quality analog. Close all background programs, make sure that the computer does not restart in the process, and that the cord is firmly inserted on both sides.
2. Run RSD Lite, in the "Filename" field, paste the path with the location of the firmware or look for it by clicking on the button with the ellipsis. Click the Show Device button to update the model list. Below, in the left window, information about the connected device will be displayed, and in the right window - about the selected firmware.
