.:Downgrade bootloader from 0A.52 to 0A.30:.

[__susanu__]

Guys here is a new method for downgrading bootloader from 0A.52 to 0A.30....

I have tested this method and worked just great...the original author of this method is DXM Dreamer

Necessary files:

1. F&B 3.0.7 [Download]

2. ramldr2_0.31 [Download]

3. boot_0A30_V3i [Download]

Dissamble v3i:















Testpoint v3i:









Connect the usb cable



Now connect the battery



Make sure the phone is detected like "S blank" if not the tp was not perform correct...check with rsd lite

Open F&B3.0.7

>> go to flash terminal
>> select from command ENUM
>> click Send button
>> everything is fine Flash & Backup write "ENUM = SBLANK"



Remove the Testpoint



Write 0A.30 boot instead 0A.52:

Start ramldr2_0.31 and connect the phone (if the phone is connected you will see bottom left corner "connected"



Press "Send loader" button if everything you will see the message "Ready"



Press "Write boot" button and choose "boot_0A30_V3i"

If everything is ok you will see the follow message

Write BOOT
OK
Shutdown
OK



Reassemble your v3i and you have 0A.30 bootloader and you will be able to do all available mods

happy modding

Where do you buy the test point cables from?

Radio Shack?
Wal-Mart?
Target?

That guide really looks easy and simple.

it's only a weird cable no need to buy one....nothing special...
