著名PSP非官方固件編寫員Dark_AleX指出﹐PSP新型底板 (編號 TA88v3) 暫時沒有方法能進行破解. 以下是部份簡介內容, 想參看全文請按下面的來源連結:

When the PSP boots, the boot code (aka pre-ipl or ipl loader) loads the ipl from either the nand or memory stick. The IPL is splitted into pieces of 0×1000 bytes.

First 0xA0 bytes of each block is a header for the kirk hardware command 1. It contains keys, the size of the cipher data, and two hashes, one for part the header itself, and another one for the body. The 0xF60 remaining bytes are the ciphered body, which will decrypt to 0xF60 plain bytes… if the hashes, which are checked by kirk hardware itself, are OK. (Note: ciphered body can actually be less than 0xF60, in this case, remaining bytes are ignored… before TA88v3)

What has Sony added to fix this?

The answer can be found in 4.00+ slim ipl’s. They decreased the size of the ciphered body to 0xF40 to leave 0×20 bytes at the end of each block (at offset 0xFE0). In newest pre-ipl’s, these 0×20 bytes have a meaning.

…

…

This protection also destroys any possibility of downgrading below 4.00, as these new cpu’s won’t be able to boot previous firmwares ipl’s.

重點翻譯:
現時最新型的PSP CPU都是以0×20 bytes數值計算來設置的, 如果能找出pre-ipl漏洞﹐新的機種便能破解.

注意: PSP-3000很有可能會用這個(編號 TA88v3)底板.

最近一些在pspgen的網友流傳Sony已發佈出PSP Firmware 固件版本 5.0 (測試版)給一些PSP研發人員測試.
這次更新更推出了Youtube視頻, 有興趣的可觀看,但可惜的是視頻語言不是英文/中文發音.

根據流傳資料顯示, 新的5.0固件版本將提供以下更新:
- 直接連線到PlayStation Store.
- 全新的RSS顯示器.
- 新增儲存PSP畫面功能, 有點像現有的自制軟件FuSa screenShoot.

注意: 本版本的更新資訊還沒有被Sony官方確定, 所有官方資訊都以Sony官方網站為準. 本版本很有機會與PSP-3000同時推出.

期待已久的 PSP 官方固件終於有消息了! 今天, Eric Lempel- PlayStation Network Operations Director 宣佈了一些有關 Sony PSP 官方固件 4.0 的資訊.

…v4.00, will be released soon, adding Google Internet search directly to the XMB (XrossMediaBar) interface.

This new upgrade replicates the Google Internet search experience, delivering the same search results that you’d get at www.google.com. And with a search history recall of 20 items, Web searches couldn’t be easier.

After you download and install the firmware on your PSP, click on the XMB’s Network icon and then the new Internet Search icon. Enter your keywords and then let Google’s algorithms do the work. You’ll need to be connected to the Internet via a wireless access point or Wi-Fi hotspot. Googling something on the go has never been more convenient on your PSP.

Another new feature delivered through the 4.00 update is the ability to change viewing speed during playback of videos stored on your Memory Stick PRO Duo, so you can speed through or slow down what you’re watching. To do this simply press the up or down directional buttons while playing a video.
