Some thought it might be impossible, others simply felt that only God's hands could code a software downgrader for the unfortunate TA-082 people. Well, let's just say that 0okm might have finally broken the shackles imposed by the TA-082 PSPs.

Firstly, a small primer for anyone new to the whole TA-082 thing. A while back, before the Undiluted Platinum modchip came out, most people were quite oblivious to the whole mobo-mania. Then it was revealed that the modchip wouldn't work with the TA-082 motherboards. Even Dark_Alex's "downdater" couldn't downgrade 'em. Few people who were brave enough to still try it were greeted by shiny bricks. Here's how you can check if you're one of the unlucky ones to have a TA-082 mobo PSP.

The reason was quite unknown. A lot of theories existed, but it was difficult to pinpoint the real problem. Well, we can safely consider it as part of the past now, because 0okm states that he has successfully downgraded a 2.50 TA-082 PSP using a software downgrader. Until now, the only other way to accomplish a downgrade was by using hardware hacks, like 0okm's multi firmware module.

Not anymore though, because we might just have a solution for the TA-082 motherboards! Here's what he states in his blog:

"Success SoftDown FW2.50 TA-082 to FW1.00/1.50

Had found a method SoftDown TA-082's FW2.50 PSP to FW1.00/1.50
But the method is quite complex, SoftDown a TA-082's PSP need about 45min

1. Use software Read Data From TA-082's NandFlash & DDR DRam
2. Analyzes the Data than make a "FW1.00/1.50 NandFlash img" that can Boot on TA-082
3. Use software Write that "FW1.00/1.50 NandFlash img" to TA-082

maybe late i will make a software to let "FW2.50 TA-082" user to dump "NandFlash & DDR DRam" data to me
than i can make the "FW1.00/1.50 NandFlash img" to help them SoftDown their TA-082 :P"

Well, so the method might take a while and it might be a bit complex. But trust the great programmers to make an easy installation method for everyone to use. 0okm has said that he might release something as a proof of concept. Keep the fireworks ready!

刚不早我发了个0okm网站出现【捐赠】链接的帖子，并怀疑他是不是要发布什么了。
因为Fanjita等破解的人，一贯也采用这一手法，希望在破解的同时也捞点外快。
这不，还没有过2个小时（我做PSP汉化游戏去了哈哈），新的新闻就出来了。大意如下：

成功实现软件降级2.5版本（包括升级到2.6的原厂2.5 psp，出厂时候是2.6的暂时不行！）TA82到 固件1.0和1.5

1   我找到一种方法可以软件降级到1.5和1.0固件。
2   但是这种方法比较复杂，分析数据大概需要花45分钟。

方法如下：

   a 利用软件读取TA-082PSP的 NandFlash & DDR DRam。
   b 分析这些数据，然后制作 TA82可以启动的FW1.00/1.50 NandFlash 镜像文件。
   c 利用软件把这些"FW1.00/1.50 NandFlash 镜像数据写入TA82的PSP

   我大概会在晚些时候发布软件，利用这个软件便可把TA82的 "NandFlash & DDR DRam" 数据dump出来。然后发给我，这样一来，我可以制作出
可以使用的"FW1.00/1.50 NandFlash img" 镜像，帮助他们达到软件降级的目的。

相信Ookm本人已经成功做出了软件并已经实验成功了。
大家不要高兴太早，但是本人有两个问题。

1  他说要把数据发给他处理才能最终实现软件降级，这样一来，人数不是一个两个人，何况Ookm也不是善角色。所以他先前的【捐助】链接就是有明显目的的。

2  0okm怎么从来都表现地这么明显，对钱。无论是他的多固件模块，还是现在。。
  不过好在他的捐款也只要10美元就可以了，想想也对得住良心。。。何况软件降级比较保险。

3 分析数据大约要花45分钟，这个也是Ookm自己说是就是说不是就不是，最终还是为了一点，自己付出了劳动，大家就要付出Money！！

各位xd 无论是TA82的，2.5的，2.6的，还有2.7的2.8的，所有想玩1.5固件的xd都要沉住气，等，死等！！

UPdate 1：
1  每个TA82的“NandFlash img（暂且称为镜像文件）”都不一样，无法使用其他PSP的，如果使用的话会变砖。所以每个数据分析需要花45分钟。
2  如果你出厂的是2.5固件（包括升级到2.6的）可以使用这种方法，如果出厂是2.6的则不行。也行我晚些时候，会研究出厂2.6的机器。
