How to update firmware on LeTV Le 1s?
You can update, install or reinstall the original stock or custom firmware on your device with two different methods.
One is SD card update and the other is Smartphone SP Flash tool from PC.
If your phone supports SD card / internal phone storage update then you can copy the custom firmware e.g. update.zip file to your SD card's root directory or in internal phone storage and install the firmware using the phone's update mode also called download mode.
LETV 1S has no external SD card slot, but has internal phone storage which can be used for the procedure. Download the official ROM update for LETV 1S here.
Simply rename to update.zip and copy the update file e.g S1_x500-OS-OP-DHXOSOP5501406011S-5.5.014S.zip or FULL_X500_X500-OS-OP-DHXOSOP5801708261S-5.8.017S.zip to the phone's internal storage. In Windows 10 just drag and drop the downloaded firmware file to the LETV 1S's icon in the File explorer tree view window or copy / paste the file.
Please note: If you have the EUI 5.5.007S old EUI system on your phone then you must upgrade it to EUI 5.5.014S first, and then you can move to newer firmware EUI release like EUI5.8.017S (Marshmallow). Check it in Settings > About phone
Be sure your battery is in good condition and has enough power at least 80%.
Put the phone in Download mode and the phone will update itself with a few click/touch. To put your phone in Download mode, first turn off the device. LETV 1S has no removable battery, so just turn the phone off. Press the Volume DOWN button and the POWER button at the same time for a few seconds until the phone gently vibrates and the LETV LOGO appears. If you have the right firmware uploaded to the phone's internal memory the flashing procedure will not start automatically but a selection screen will show up. A check mark will be displayed next to the UPDATE system option. (If you have the chinese version see picture above and below the english version, just select the default button colored blue) Also check the Clear data option but only if you have a backup of your data and you want a clean install formatting the device after firmware update. It usually will take only a few minutes to update the system. (Do not forget to rename the firmware file to update.zip and double check the extension, if it is update.zip.zip or something, it can cause error and you will not be able to update your system.)
After you installed 5.5.014S version, you can upgrade to Android 6.0 Marshmallow based EUI 5.8.017S or later. Repeat the previous steps. If you have the LETV 1s chinese version ROM just select the upper option contains update.zip and the right button which is the START update button. If you want to cancel the firmware update just press the left button which will restart the phone without any modification. After you pressed the Start button you can step back using the power button, it will cancel the action.
