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

Wrongly done S-ON with Security Warning - Downgrade New S-ON Devices Firmware For Revolutionary S-OFF

you have to verify with htc or your carrier if you are allowed to use this method

htc dev method is used to solve this Problem , this method is

the only known working solution

for that Brick problem till now

Revolutionary will not work with the New Firmware that comes with some New Devices or Devices that accepted the OTA update

Also this Method is implemented through using htc dev method to Downgrade that New Firmware and Successfully Get Revolutionary S-OFF

Install any ICS Custom Rom for ( S-ON Devices with hboot 1.27.0000 )

See post # 2 in my other thread here ,

for how to install any ICS custom Rom

while you are S-ON with hboot 1.27.0000

WiFi Error and Custom Roms

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

Unlock Bootloader using htc dev Unlock Method ( may or could void your warranty ) or Super tool or Check this Post in XDA Portal ( if it is legal to use them ) 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 )

How to flash Boot.img in Bootloader

Update there is now a new version of 4EXT recovery for S-ON devices v 1.0.0.5 , enable smart flashing in recovery \ tools and it will flash the boot.img by itself " read the restrictions for that method in 4EXT recovery thread "

Bootloader should be unlocked using htc dev or super tool or Check this Post in XDA Portal ( if it is legal to use them )

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

to install your custom Rom ( See link in " Other Posts Links "above or click here ) , Follow title " Custom Rom Flash " and " [FONT=&quot][ Implementation ][/FONT][FONT=&quot] using the above method by member su-27 "[/FONT]

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

Update there is now a new version of 4EXT recovery for S-ON devices v 1.0.0.5 , enable smart flashing in recovery \ tools and it will flash the boot.img by itself " read the restrictions for that method in 4EXT recovery thread "

Bootloader should be unlocked using htc dev or super tool or Check this Post in XDA Portal ( if it is legal to use them )

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 Sensation version

( Sensation , Sensation 4G , Sensation XE ) , htc method will only allow signed Radio specific for your device , and

i guess

( not sure ) it will not allow you to flash a radio for a different Sensation device !!!

Example is (

not sure

) , ARHD ROM is Based on sensation XE and most probably their recommended Radio is a sensation XE Radio , if this radio is not officially assigned to your Device by htc , then

i guess

htc method will not allow that ( because i guess the option in bootloader is still locked )
