Before flashing, charge the phone by more than 30%!
Method 1 - recommended. 1) Connect the included phone to the computer with a cable;
2) Make sure that an ActiveSync (or Windows Mobile Center) session is established;
3) Run the firmware file on the computer and follow the instructions on the screen.
Method 2 .
Used when the phone does not load or is loaded incorrectly. 1) Connect the switched off phone to the computer;
2) Press the volume key down and, while holding it, turn on the phone. Boot bootloader, the so-called "mattress";
3) Run the firmware file on the computer and follow the instructions on the screen.
Method 3 - from microSD memory card. It is recommended only if you want to change the SPL version (and you know what it is and why), or when methods 1 and 2 are not available. 1) Unpack the firmware on the computer (if the exe file is just to run it, do not press anything, go to the TEMP directory and look there);
2) Write to the memory card RUU_Signed.nbh and rename it to LEOIMG.nbh. As a rule, it is not required to format the card;
3) Press the volume key down and, while holding it down, turn on the phone. Boot bootloader, the so-called "mattress". The firmware from the memory card will start automatically.
After flashing, some recommend immediately making a hard reset (see
FAQ), but the expediency of this is not proven by anyone.
Attention! Official firmware without problems can be put on those phones for which they are released (Russian - in Russian, T-mobile on T-mobile, and etc.). To install official firmware on a phone for which it is not intended (for example, from another region) you may have to use HSPL - to install the entire firmware, or SSPL - to install the PART OF the firmware without a radio module. For details, see the cap in the topic.
