Problem with esp32 program uploading,thanks in advance

[elboundganesh]

I am totally newbie with ESP32.but i am familiar with arduino,cypress.
I have esp32 -evb board,using that board i worked in ethernet ,ir ,relay control ,wifi,bluetooth using arduino ide and obtained desired output.
yesterday my esp32 ic in esp32 evb board malfunctioned and got short circuited (still figuring reason for short circuit),the esp32-evb board have esp32 WROOM,now i bought a esp32 WRover ic ,i de-soldered ESP32 wROOM and soldered esp32 WROVER's gnd,vcc,tx(UART),RX(UART) to respective gpio pins of ESP32 evb development board.now when i dump a example program it shows following error in arduino ide when uploading:

Global variables use 38032 bytes (12%) of dynamic memory, leaving 256880 bytes for local variables. Maximum is 294912 bytes.
esptool.py v2.3.1
Connecting........_____....._____....._____....._____....._____....._____....._____....._____....._____....._____

so i followed different approach,
approach 1:i took a arduino uno used it as usb to uart converter by removing the atmel micro controller and connected 3.3v,gnd,uart tx,uart rx to ESP32 WROVER .I connected a button with pullup resistor to en pin,gpio0(when corresponding button is pressed gpio0 or en pin will be grounded).now when i upload program same problem occurs.
approach 2:i used cypress usb to uard converter instead of arduino,still same error occurs.
approach 3:i programmed it with ESP32-IDF(i have alreadey worked with this meathod,so the software configuration is perfect),now it displays with following error
Flashing binaries to serial port COM10 (app at offset 0x10000)...
esptool.py v2.3.1
Connecting........_____....._____....._____....._____....._____....._____.....__ ___....._____....._____....._____

A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
make: *** [/c/esp32/esp-idf/components/esptool_py/Makefile.projbuild:55: flash] Error 2

i have also tried holding the boot button and pressing the enable button to initiate the firmware download mode,still the program doesn't get uploaded.sorry for my bad English,your help is very much appreciated,thanks in advance.
