Hello guys

Today i am going to give you a very small tip may you people like it ....
i used 2.3.4_283 firmware in Arc for a long time , after that i flashed 42 firmware and feel that its drain battery fast as compare to 283 firmware either you are using you phone or it is in deep sleep mod
Then i flashed 58 firmware and after that 62 firmware but battery drains still fast
then i try one thing on my arc i get the Kernel from 283 firmware and flashed it on all three version of firmwares ( 42, 58, 62 ) and notice that the issue of fast battery drain is solved it is only because of 283 kernel "

now i am using 42 firmware with baseband 64 and kernel from 283 firmware

It does'n matter what ever the firmware you are using or what ever the baseband you are using ....... you need to use kernel from 283 firmware only for low battery drains ..............

i attached kernel from global generic wold 283 firmware also...

How to flash different Kernels

1) connect your phone into fast boot

2) open cmd

3) fastboot devices
(write this command and enter it to check your phone is connected in
fastboot or not)

4) then write this and enter

fastboot flash boot kernel.sin

Done ..........

remember to copy kernel .sin file in that folder from where you are going to launch cmd

=============================================================================================================

I have done this already and my ARC S works completely fine.

This how I have done it

-----------------------------------------------------------------------------

Requirements:

LT18i_4.0.2.A.0.58(2.3.4)_HK firmware (Download from here)
The Kernel from .283 (Download the KERNEL here)
Flash Tool ( Download from here)
WinZip/Winrar or any other similar software.

Steps

---------------------------------------------------------------------------------------------------------------------------------------------------------

Step 1: Download the LT18i_4.0.2.A.0.58 (2.3.4) _HK firmware

Unzip the firmware *.ftf file using WinZip or Winrar.
You will get a folder like this.

Step 2: Download the Kernel file

Unzip the file
You will get a file named “Kernel.sin

Step 3: Copy the “Kernel.sin” file

Paste the file to the firmware (LT18i_4.0.2.A.0.58 (2.3.4) _HK) folder and replace it.

NOW OPEN FLASH TOOL FOLDER. YOU SHOULD SEE FIVE FOLDERS WITHIN IT.

Step 4: Copy the LT18i_4.0.2.A.0.58 (2.3.4) _HK folder

Step 5: Paste the folder within firmwares folder

Step 5: Click on Flash Tool .exe

Click on Advanced from the menu
Select bundle creation

Step 6: Click “select source folder” (click on the doted button)

Step 7: Select the folder that you have copied in Flash Tool/ firmwares folder (LT18i_4.0.2.A.0.58 (2.3.4)

Step 8: You will get all the file list on the left side

Step 9: Select all file and click on the “Right Arrow” button.

All files should be now at right side.

Step 10: Put anything in this 3 boxes (doesn’t really matter)

I have put following

Device: LT18i
Version: 0.58_283
Branding: Stock SE

Step 11: Click OK and wait.

Step 12: When you will see the "Finished bundle creation" message, then the firmware is ready.

Step 13: Check the Flash Tool/firmwares folder. You should get your new firmware “LT18i_0.58_283_Stock SE.ftf” file there.

IF you DO, then just flash your device with this firmware.

All done.

**Important**:

I am not responsible if anything goes wrong, so proceed carefully, do not miss any step.
I have tested this kernel combination with both 0.42 & 0.58 firmware and it works fine in ARC S.
0.62 firmware (didn’t worked for me)
You can easily root this firmware using the zergRush method.
