Since htc Incredible 2 ( VIVOW ) is now officially Supported by htc dev Site ( it was unofficially supported before that ) , and that Some members may want to use this htc Unlock Method .

And due to the Fact that this htc Unlock Method causes different kinds of errors which I could figure out why they happened and how to solve ( it does not prompt you that an error has happened )

I thought of adding this Post for Incredible 2 Also , I originally Posted it in Sensation Section

How htc dev unlock method Works

first of all , i don't like this method ( htc dev unlock method ) because it is tricky

this method unlocks some options for Bootloader ( Not All of them ) . htc dev site as i recall says unlocking your bootloader may or could void your warranty !!

the Boot.img and Bootloader are still locked , and of course the Radio area is still locked ( it is not the radio we flash to improve signal )

locked means those areas can not be over-written

it allows you to install Custom Roms , But what htc maybe forgot to tell you is that the custom rom should be using their htc Stock kernel in order to work without errors !!!!!!! . ( Otherwise for Roms with custom kernels , you have to install Custom Kernels in a certain Method to avoid errors like WiFi error !!!! )

this certain Method is to flash locked items ( like Boot.img that includes custom Kernel ) through fastboot ( i.e bootloader )

S-ON

htc dev unlock method does not give S-off , it only unlocks some options for Bootloader . so ,what you saw ( Unlocked and S-on ) is normal for htc method

Some mistakenly think that htc dev unlock method is the same as Revolutionary S-OFF ,

AND IT IS NOT

WiFi Error and Custom Roms

the following is for members who used htc dev to unlock bootloader instead of doing Revolutionary S-OFF . S-OFF devices will not have that WiFi error

Unlock Bootloader using htc dev Unlock Method ( may or could void your warranty ) or Super tool ( if it is legal to use it ) and ( use htc drivers v3.0.0.7 )

you can use a Custom Rom that uses a Custom Kernel ,and solve WiFi error ( while you still on htc dev unlock method , i.e NOT S-OFF ) by installing the Boot.img ( includes custom kernel ) bootloader

if the Custom rom uses the

Exact same version

of htc Stock Kernel ,you will not have WiFi Error

Wifi error is usually happens because of the kernel ( in your case it is because of kernel mismatch )

in htc Method the Boot.img is still locked , Note that the Boot.img includes the Kernel

the kernel is located inside Boot.img , and Also the kernel components ( when you install a rom ) are located in System \ lib \ modules . the Module Folder is a Kernel Folder . if there is a mismatch between kernel and kernel components you will have WiFi error

a sample case , the Boot.img is still the htc stock Boot.img ( i.e it includes the stock htc Kernel ) , and you installed a custom Rom that includes a custom Kernel

When the Custom rom is being installed it will not be able to replace htc Stock Boot.img ( i.e the Stock Kernel , because it is locked ) , But will be able to install kernel components System \ lib \ modules ( because it is Unlocked ) , and

Here comes the kernel mismatch and the WiFi Error

( the Kernel is still the htc stock kernel , and the Kernel components are for a different custom Kernel )

DISCLAIMER

Verify with HTC and your Carrier that you are legally Allowed to use any Method in this Post Before using it ,

and Don't use it if you are not legally allowed to

I am not responsible if following this Method results in bricking your phone

Whatever you do is at your Own Risk​

[FONT=&quot]Custom Rom Flash

[/FONT]

Unlocked bootloader using the htc dev unlock method ( may or could void your warranty ) or Super tool ( if it is legal to use it ) and ( use htc drivers v3.0.0.7 )

Do a NAND backup for your rom , then do a full wipe or use Super wipe

flash the Custom rom from Reboot into bootloader

Extract Boot.img from the

same

rom zip

you flashed , ( in Multi device Roms , extraxt the boot.img for your exact device ) , then Flash it as follows :

How to flash Boot.img in Bootloader

Bootloader should be unlocked using htc dev or super tool ( if it is legal to use it )

the phone should be in bootloader ( fastboot usb )

Put boot.img inside adb folder in same place your fastboot.exe

Start cmd

as administrator

and navigate to ADB Folder which includes fastboot.exe and type the command fastboot flash boot boot.img and press enter

type the command fastboot reboot and press enter

Reboot , the device may reboot several times before reaching the home screen

this Procedure souled be done for each custom rom you install to avoid WiFi error or other errors

[/FONT][ Update ] Alternative Method to Flash Boot.img for Custom Roms

Bootloader should be unlocked using htc dev or super tool ( if it is legal to use it )

the phone should be in bootloader ( fastboot usb )

Download recovery img for either CWM or 4EXT

Put recovery img ( recovery name.img ) inside ADB folder in same place your fastboot.exe ,

recovery name.

img

is the exact name for the downloaded recovery

img

that you put inside the ADB Folder

it is

NOT

PG58IMG.zip recovery

Start cmd

as administrator

and navigate to ADB Folder which includes fastboot.exe and type the command fastboot boot recovery name.img and press enter

your phone should now go to recovery screen ( loaded through fastboot )

install your custom rom as normal and reboot your phone , ( this will install the custom Rom and the Boot.img of the same Custom Rom in the same time )

Reboot , the device may reboot several times before reaching the home screen

if this method doesn't work , then go back to the original Method

Radio Flashing Problem

in htc dev unlock method , the Radio is also still locked and most probably htc dev

will not allow you

to flash a radio alone

and

in case

that htc dev shall allow it ( i doubt that ) ,

then theoretically

!!!! :

you have to flash an official release Radio

specific for your device

, htc method will only allow signed Radio specific for your device
