Your PSP is then a useless "Birck".
It can be reverted to a prior firmware but it is very very long and excruciatingly painful process to do.
Recently you can not make your psp with a custom firmware with out Pandora, Think about buying a Pandora battery on eBay, they are cheap.
Im not quite sure, but from what ive heard there are mixed reviews. Some say that you cant downgrade a 3.90 firmwire. Some say that you can downgrade any firmwire with a pandora's battery. Its quite confusing to me. I havent do it because im not sure what will happen. I, too, have a 3.90 firmwire. I dont want to waste a perfectly good battery trying to make a pandora's that might not even work. But i am getting closer to my answer. Im still leaning toward making the magic memory stick and pandora's battery. Ive read so many instructions on how to do it I can make my own forum and tell people how to do it.
you need: - Pandora's battery- you can buy it from Deal extreme.com - Pandora's memory stick - you can buy it, or you can make it using a computer; search Google for "how to make a Pandora's memory stick" - computer by anonymous457
Follow this guide http://forums.noobz.eu/downgrader-support/pandoras-battery-jigkick-battery-and-magic-memory-stick-tutorial-guide/0/ it will show you how to make a MMS, and its the guide I used.
you can only go from 3.72 official firmware to 3.90 custom by using a Pandora battery to downgrade your psp to 1.5 then upgrade to 3.90. to obtain a Pandora battery you cam buy one from eBay or if you know someone on custom firmware, they can make one. (WARNING, once your psp battery has been turned into a Pandora battery it can't be used as a normal battery)
There are two types of this battery,when opened,if yours has the motherboard at the top of the battery,were you charge it,it can be turned into a pandora battery,the best idea is to search "pandora psp-280 3.6v 2200 mAh battery" in youtube,youll have it in two secs ;) . if the motherboard is beneth the front panel,i believe it can NOT be hacked. I have one of the same battery and can not find a tutorial on doing it. I hope this helps, Yours Sincerely, M1lk3y

Here's all the info that the other sellers are trying to sell you. What they don't want you to know is that it's all available freely on the internet. First, some basic facts: 1. The Pandora Battery is actually a combination of specially-modified PSP battery, and specially-modified PSP pro duo memory stick. 2. It allows you to unbrick, or downgrade, ANY PSP, regardless of current firmware, as many times as you like. 3. Although you can convert the Pandora Battery back to an ordinary battery, you're recommended to use a spare battery, as it is more convenient and flexible. 4. To make a Pandora Battery, you need a homebrew-capable PSP. If you don't have a homebrew-capable PSP, you should find a friend who does, or use the information below to find someone who can make a battery for you, for free. So how do you get started? 1. Click here for the original release article, that contains links to download all of the software that you could need. 2. Here's a set of lists of volunteers who will unbrick, downgrade or make a Pandora Battery for you for free, or a minimal donation: 1. Via the Noobz Forums 2. Collected from the QJ / MaxConsole Forums 3. Click here for an easy-to-follow guide for creating and using the Pandora Battery. 4. For cheap prices on spare PSP batteries that are guaranteed for compatibility, click here (UK) or here (US) . Some scams to beware of: 1. Some people are selling the battery on its own, plus instructions on how to make the memory stick. Making the battery is the easy part, and if your PSP is unable to do that, then you will be unable to make the memory stick. 2. Selling the memory stick is illegal. 3. Many people will try to sell you just the instructions. There are some excellent instructions available for free on the internet, including those linked to above. 4. Many people are simply selling you a link to the website containing the download.
