首先，現確定你有以下幾樣東西：
First of all, let's make sure that you have following things :
1. 你必須是1.50或者2.71SE-B/C的系統。
1. Your psp has to be FW 1.50 or 2.71SE.
2. 你準備好了2.71和2.82的兩個升級文件的EBOOT.請某人補上這兩個文件的地址。
2. You have both 2.71 and 2.82 update eboot, which is required to generate the file dumps for devhook 0.50.
3. 你有一個可以解開PBP文件格式的工具。推薦用PSP UNPACKER : 下載
3. You have a tool that is able to unpack PBP file, I personally suggest you get a PSP Unpacker. download here
4. 你有一個PSAR dumper,可以從Dark_AleX的網站上下載。
http://dax.lan.st/ 4. You have D_A's PSAR dumper. grab one from his website.
http://dax.lan.st/ 5. 當然最後就是需要Devhook 0.50了。
5. Devhook 0.50 from Booster.
有了以上幾樣東西，你就可以開始了。
once you have these things, you're ready for the following.

複製需要的文件到PSP
copy necessarily files into your psp:
如果是1.50，那麼只需要把壓縮包內的MS_ROOT文件夾裡的所有東西複製到PSP的根目錄。
If your psp is still tucked in FW 1.50, just simply copy everything inside MS_ROOT folder to ms0:/
如果是2.71SE-B/C，需要把壓縮包內的MS_ROOT文件夾裡的所有東西複製到PSP的根目錄。然後因為devhook是1.50的程序，所以你知道該怎麼做拉。
If it's a 2.71SE, copy everything inside MS_ROOT folder to ms0:/. Now since devhook is an 1.50 homebrew, chose your folder (game or game150) to put these __SCE__DH_ENG and %__SCE__DH_ENG folders.
建議，先把你原來的ms0:/dh和ms0:/psp 這兩個目錄改名，不然如果你想換回0.46版的時候就不太方便了.
Tip : I suggest you to backup your ms0:/dh and ms0:/psp, in case if you want to go back to devhook 0.46.
然後，複製PSAR dumper到你的ms0:/PSP/game或者ms0:/PSP/game150。視你的系統版本而定。
Then, copy PSAR dumper to your PSP, ms0:/psp/game or game150, depends on which fw version do you currently have.

拿到需要的文件
Install the file dumps.
1. 用PSP Unpacker打開2.71的升級EBOOT.PBP,然後選擇下方文件列表中的 DATA.PSAR，然後選 Extract ...並指定把這個文件解壓縮(Extract）到psp的跟目錄下。
1. Open and extract the DATA.PSAR from 2.71's update eboot by using PSP Unpacker(or any app you prefer). Save this file in ms0:/
2. 從PSP裡運行PSAR dumper 0.2B，然後按方塊按鈕。程序就會開始解壓，完成後會自動退出。
2. Run PSAR dumper 0.2B, when the screen appeared, press SQUARE button. then wait for a while, when it's finished, it will automatically return to the XMB.
3. 在PSP根目錄下你會看到一個F0目錄，這就是剛才解壓出來的文件。你需要進入F0/kd，並把裡面的audio.prx這個文件複製到其他地方。我們後面用得著。這步相當重要，否則
2.82沒有聲音。保存好這個文件後，就刪除掉這個F0目錄。
3. Now copy ms0:/F0/kd/audio.prx and save it to somewhere else. this file is very important, without it your 2.82 will be muted. When this file is saved, you can delete the whole F0 folder. we don't need it anymore.
4. 重複步驟1～2，不同的是，這次我們要搞定的是2.82的升級EBOOT. 還有就是這次運行PSAR dumper的時候，切記要按X按鈕。
4. repeat setp 1 and 2, but this time you'll need to do it with 2.82 update eboot, and this time when you run PSAR dumper, press CROSS button.
5. 完成解壓縮後程序自動退出，這時候你的PSP根目錄下有一個F0文件夾。你需要把剛才保存的audio.prx覆蓋到F0/kd目錄中。
5. When it's finished you'll return to XMB, and there is a ms0:/F0. Now, remember the 2.71 audio.prx you've saved at step 3? you have to copy that file and overwrite to ms0:/F0/kd.
6. 然後，我們複製（或剪切）整個F0文件夾，並把它粘貼到ms0:/dh/282目錄下。
6. we're almost done, now copy and paste ms0:/F0 to ms0:/dh/282, overwrite everything.
文件生成的部分完成了。
file dumps is now installed.

設置devhook
setting up devhook with FW 2.82 emulation.
要使用devhook 0.50來模擬2.82，你必須要把配置文件刷到Flash1，Devhook會幫你做這一步。如果你還是對刷機這個詞過敏，建議你老老實實用0.46就好了。
Note: In order to emulate FW 2.82 with devhook 0.50, you'll HAVE to flash configure file into your PSP, don't worry Devhook 0.50 will take care of it. if you're not comfortable with flashing, well...devhook 0.46 might be your best choice.
以下是步驟：
1. 運行 DEVHOOK0.50 ENG launcher
1. Run DEVHOOK0.50 ENG launcher from XMB
2. 選擇"FLASH ROM" ，然後選擇 "flash1: < ms0: install configfile" 並按住O鍵不放。——1.50的用戶注意，如果你之前用過這個功能，那麼你必須先選flash1 remove all devhook files 來刪除原先的文件，否則便不會通過這步；2.71SE-B/C的用戶不用擔心，只管刷下去就好了。、
2. Go to 'FLASH ROM' and select "flash1: < ms0: install configfile", some warning shows up, don't worry just press and hold O key for more than 1 second, let it flash configure file to your Flash1. Note to 1.50 users, if you have used this feature in any previously devhook releases, you'll have first to 'remove all devhook files' before go any forward, otherwise you won't be succeed.
3. 在Firmware菜單裡，選擇2.82
3. In "FIRMWARE", select 2.82
4. 因為第一次啟動2.82的時候會提示系統損壞，所以我會建議你在BOOT MODE裡面選擇XMB MENU.否則如果按默認的選擇DEVHOK MENU的話，多語言藍屏出現的時候會死機。
4. Now, go to 'BOOT MODE' and choose "XMB MENU". because when the first time 2.82 boots up, It will show you the muilt-language erroe screen and you have to press O key to fix it. At this point if you chose "DEVHOOK MENU", your PSP will hang.
5. 接下來就是按START來啟動devhook了。 在XMB界面可以按HOME按鈕呼出菜單。
5. Now we're ready to go. press HOME button at XMB will bring up setup menu.

-----------------------------
加入： 按下Home 按鈕時可設定GUI。
加入： 可以隨時切換ISO/UMD模式而不用重新啟動。
加入： 2.80/2.82 Firmware 模擬啟動。
對源碼進行的維護：
刪除： 1.50, 2.00, 2.50 和 2.60的支持。
刪除： 對應1.50版本遊戲的NOUMD代碼。
改變： devhook的 API大幅度更改，增加simple registry system。
改變： 增進了界面菜單。
改變： launcher界面的配置文件結構更改。
加入： mokr04a的更改字體系統（個人認為Chunglam的才是王道)
以及其他的一些驅動更改。
已知的問題
使用快捷鍵從Devhook回到普通firmware無法正確執行。
從菜單界面中是完全無法退出到普通firmware的。
Vshex （XMB的設置界面)有時會卡死
