Note: The recommended install method for fake-flash is now 'ROM Manager' on the Android Market.

This morning, Koush and I have been working on / stumbling through getting recovery running on a Desire without using a PC for devices rooted with a test image. The same technique also applies to the Legend. Presenting...

fake-flash!

Fake-flash using a similar concept to the original root method, it launches a recovery image from the test image recovery, but instead of pushing the files from a PC, the files are extracted from an update.zip on the SD card. Here's how it works...

Preperation
  • Download the fake-flash update zip from one of the links below
  • Copy the update.zip to the root of your SD card (the name MUST remain as update.zip)
When you want to launch the recovery image
  • Turn on your device with 'volume down' pressed and select 'Recovery'
  • When the exclamation mark appears, press and hold 'volume up' then press 'power'
  • Select the second option, 'Apply sdcard:update.zip
  • That's it, ClockworkMod recovery should launch! :)
Neat eh?

DOWNLOAD

Just to caveat this initial release, we've yet to carry out extensive testing and you are constrained somewhat by the limitations of the stock kernel (e.g. no support for EXT4).

That's it for now... enjoy... i'll update this post as further advances are made. If you'd like to support Koush's work, consider buying 'ROM Manager Premium' from the Android Market.

I read the transcript, you are being too modest, you guys did helluva job.
Makes me want to buy the desire and not wait for the evo to come to Europe.

Paul, just to clarify, when you say 'constrained somewhat by limitations of the stock kernel' are you saying we should not use this if we have a custom kernel?

I suspect not but I can see the question cropping up :)

Brilliant, just used it to do a nandroid backup and re-flash a froyo rom. Excellent job Koush and Paul :)

Just an update, didnt notice at the time but as Nicke below me says, nandroid is currently not working - goes through the backup procedure then fails on generating md5 sum

I tried nandroid and got:
"Generating md5 sum...
Error while generating md5 sum!"
when backup was done.

I seem to get a black screen when I select any of the options from the Recovery menu. I have an HTC Desire with 0.80 HBoot and stock rooted ROM.

Oh, I get it. I was using the power on button to select options which turns the screen off. Anyway, you have to use the trackpad press to select an option. Great work!

There might be a few quirks to iron out... Koush had to sleep (it's nearly 3am there, lol!)
