نعم إذا كنت تملك 2.00 يمكنك أن تعيد الفيرجن إلى 1.50
وهذه الطريقة : (مأخودة من الكتاب pspHelp المذكور أعلاه)

Before you can downgrade you need to make sure you have 2.0 firmware. If you are using 1.51 or 1.52 make sure you download the 2.0 Eboot from your favorite PSP website. This does not include Sony's site, they have 2.50 on their site, and same goes for Network Update from within the PSP's homemenu.) If you update to 2.01 or 2.50 you will not be able to downgrade!!!
I will explain how to upgrade before downgrading for all of you 1.5x's. Even if you have 1.50 and want to upgrade to 2.0 to check out the features you can follow along. Upgrading is pretty simple; you want to make sure you have a working version of the 2.0 update firmware. I would recommend getting it from PSPUpdates or PSP-Hacks. Once you have the file, you want to create an UPDATE folder under PSP/GAME. Now there have been a lot of people saying the folder has to be all caps. But, I am updating as I am typing this and I made an update folder with all lower case letters, and it is working so I am guessing the update folder name is not case sensitive. Now that we have the UPDATE folder created lets put the 2.0 update in there. Before going further you want to make sure you have the AC Adapter or USB power plugged into the PSP. On the homemenu go to Game/Memory Stick, Hit X and you should see the Update file. Make sure that the update file says "PSP Update ver 2.00". If this is the case lets hit X, If not download the 2.0 Update Eboot from another site. Now, Hit X on the Update and it will load. Give it a few seconds then follow the onscreen prompts. Some people have had trouble updating to 2.0 after using a version changer. If you have used a version changer and can not update, make sure to change your version back to 1.50 and restore Default Settings in System Settings on the homemenu. If the update loads without a problem, you will have to hit right a few times, and then hit down to Accept the agreement. Once you agree you will see a status bar counting up. Give it 3-5 minutes to complete the update. At the end it will say to hit X to reboot the PSP. Do what it says and when it reboots you will have 2.0! The only features in this firmware that I really wish 1.50 had, is the Web Browser which you will see the icon for as soon as the homemenu loads, and the Themes settings. Themes allow you to set a full size background and also change the color scheme. All of the other features can be accomplished with homebrew. Take your time and mess with 2.0 and use its browser, its quite cool. As long as you have the 1.50 Eboot and MPH's Downgrader you can return to 1.50 anytime you want.
::CAUTION:: I have heard stories that the flash memory where the firmware is stored can only be written to so many times before it becomes corrupt. No one knows for sure how many times till this happens and I have heard numbers from 250 times to 1000 times. Which ever number is correct, you don’t want to upgrade and downgrade constantly. Also, there are a lot of people that are worried about bricking their PSP's from downgrading. No one I have spoken to has bricked their PSP yet. I've read on the forums that people have, but I have also read in a forum that someone hung out with Elvis, Jimmy Hoffa and Aliens from 3 galaxies away just last week. So take what you hear from these lamers and use it at your own discretion.
On to the downgrading…Now before we downgrade, you want to make sure to have two things: first you need the 1.50 Update Eboot and MPH’s Downgrader. Both of these files can be downloaded from PSPUpdates or PSP-Hacks. If you still have the UPDATE folder from updating to 2.0, just delete the Eboot for 2.0 and put the 1.50 Eboot in there. If you haven’t extracted MPH’s downgrader yet, do so now. In Windows Explorer go to the folder that you extracted the downgrader to, holding cntrl while you click on the PSP folder, h.bin and index.dat, will highlight those three files, right click in the blue space on the files and hit copy. The only other file that should be in the .RAR file is a downgrader.txt, this you do not need to copy to the PSP. (Doesn’t hurt anything if you do, but it is not needed.) Now if the PSP is not in USB Mode turn it on and right click in the white space of ROOT and click paste. Hit yes to copy over the PSP folder and if anything else comes up hit yes.
Your PSP folders should look like this:
حمل الكتاب و سترى الصور هنا :D
This is the ROOT
This is the path to UPDATE
Ok we are now ready to downgrade. Go to the homemenu and scroll to photo. Click X and your PSP screen should turn black with some white characters. Looks kind of weird but that’s ok, it’s doing its job in the background. Give it about 30 seconds then hold your power switch up for about 10 seconds till the psp shuts down. When you turn it back on it will go to the homemenu like normal, but if you scroll to System Settings/ System Information, you will notice that your System Software Version will be 1.00. Scroll to Game, click X and run the PSP Update ver 1.50. Now you want to hit right on the d-pad once and then hit X. It will start to install 1.50. The update will go to 99% and give you an error. The error says “The update failed. Contact the Sony Computer Entertainment technical support line for assistance. (ffffffff) But this is fine. We don’t have to contact Sony ( they would most likely laugh at us if we did) We are going to shutdown the PSP by holding the power switch up for 10 seconds. Once it shuts off turn it back on. You will get a blue screen saying “Setting information is corrupted. Press O button to repair and restore default settings.” Well let’s listen to the damn thing and hit O. Your memory stick light will flicker for a second or two and the PSP will reboot itself and you will have to go thru the initial setup again. The initial setup is what you had to do the first time you powered on your PSP. Set your language, time zone, time and date, and name you’re PSP, then hit X to save settings and you are now running a homebrew enabled 1.50 PSP!!! Once you have finished this you can either format your memory stick or delete the files from it manually, they are no longer needed. Read the rest of this helpfile to learn all about homebrew games and tools.
و إذا كنت مستعجلاً فهذه نصيحتي :
- إبحت عن psp 1.50 فإن لم تجد فأي فيرجن حتى 2.00 يفي بالغرض فإن لم تجد فأي فرجن حتى 2.60 لماذا ؟
لأن الفيرجن 2.5/2.6 يمكن تنزيلهما إلى 1.50 وهذه طريقة حديتة و قد لاقت نجاح كبير كما قلت لك سابقاً المهم أن هناك أمل
ومن كل هذا إياك تم إياك إقتناء psp بالفيرجن 2.70 فما فوق 
- عند شرائك لـpsp تأكد أنها ليست من النوع TA-082 و ذلك بعدم وجود الكتابة "IC1003" في مكان UMD كما هو مبين هنا
لأن psp AT-082 لا يوجد لها طريقة تنزيل إلى 1.50 ولا تعمل معها المود شيب (mod-chip) المتواجدة في الأسواق
- نعم كما قرأت هناك mod-chip بإسم Undiluted Platinium تسمح لك بالتنقل بين الفيرجن 1.5 و أي فيرجن أكبر من 2.00 (لأن هناك ألعاب تتطلب فيرجن 2.5 أو أكتر لنعمل على psp لكنها عدد هذه الألعاب قليل على العموم هناك برنامج devhook)
سلبيات الـmodchip هو أن تتبيتها مهمة معقدة و تختلف حسب نوع psp و كذالك تمنها مرتفع (حوالي 90 euro تقريباً)
هذا متال لطريقة تتبيتها على psp من نوع TA-081
- و لا تنسى أن تتأكد من أخد psp بجميع لوازمها من memory 32 Mb و سماعات sony بـجهاز تحكم و كذلك بطارية شحن من نوع sony لأن غيرها سيؤدي إلى تخريب psp 
...إلخ
أرجو أني كنت واضح
سلام ...
