letv_le_1sletv_le_1sHOW TO UNBRICK LETV X500 (RED LIGHT problem)

Requirements:-First, and most important, you need some drivers to install for MTK preload to work, if you have windows 10 it wont work! I try on win7 and installation goes well.
PDAnet drivers doesn`t work with this problem, because you can`t turn on USB debugging ON on phone. Driver 


2. Download This Firmware – LeTv_S1_x500-multilanguages-5.5.007stable or S1_x500-CN-OP-DBXCNOP5501001211S-5.5.010S


3.Download  and extract SP-Flash-Tool-v5.1532.00 (only this version works with my phone without any errors)

FLASHING: – Install drivers

LE

  • Then open flash tool.

LE2

  • Extract ROM to desktop and find scatter file in flashtool.

LE3

  • Choose update firmware and FIRST press DOWNLOAD button and AFTER THAT CONNECT PHONE TO USB, REMEMBER THAT IF YOU CHOSE “FORMAT ALL+DOWNLOAD” YOU WILL LOSE YOUR IMEI! I BACK MY IMEI ON EVERY PHONE FIRST DAY WHEN I GET IT AND THAT’S REALY GOOD FOR THIS CASE SCENARIO.

LE4

  • AFTER FLASHING IF YOU STILL GET RED LIGHT, PUT PHONE ON ORIGINAL CHARGER AND AFTER 15-20 MIN TRY TO PRESS POWER MORE 10 SEC , PHONE SHOULD BE VIBRATE AND POWER UP FEW SECONDS!
