Fake-flash by Koush, launching recovery on your device without a PC

[Guest moran679]

I think this is all running away a bit too fast. I've been following these forums since before Paul's root method came out and have no idea what's going on here or why this is useful.

Hate to be a pain, but it would help me (and I presume others) if the first posts of these stickies actually explained what was going on and why these things are useful. For instance, what does it mean to have a test image installed? If I'm running an MCR, does that count? Are you supposed to keep the update.zip on your SD card permanently? If so how do you flash new roms? Alternatively some kind of tutorial or glossary would rock. I appreciate the time that goes into these things, but this is all getting a bit frustrating.

Sorry for being thick.

I'm with him.. I too have been following these forums since before the root method, and have no idea what the hell is going on.

What's this "test image" you all keep mentioning? I thought that when rooting I install a recovery. Does this all work with the custom kernel? How about the USB brick issue, does this recovery fix it? Why isn't it all a part of the rooting method? (the USB brick fix and this recovery). What about full write access to /system ? Why do we need it? Has it been accomplished? What are we doing without it?

Also, the whole A2SD situation is vague. What's A2SD+, why do I want it over A2SD, does it work, how does it even work?

The test image was what you flashed during step 1 of the rooting process.

It should work with a custom kernel, it did on mine anyway.

This recovery doesn't fix the usb brick issue, but this recovery shouldn't cause a usb brick (i don't think), so it should be safer.

Access to system has not been achieved yet, but full system access is available via recovery anyway.

A2sd+ is the same as a2sd except that dalvik-cache is moved to the SD card too, but I don't really know what it means.

I have a rooted device.

Just tried this method and it ended up badly.

I got some error that /sdcard/update.zip is not found... i rebooted my phone and when it booted the SD is shown as damaged. :) When I swap it into a card reader I can see all the content on my ubuntu... ext2, fat32, swap.. everything seems to be ok... what went wrong? How can i repair it? Please give some advice...

EDIT:

chkdsk stops at 10 percent in windows... nice

Koush and Paul: Thank you so much! This works great! You guys finally did it :)

[Guest akirita]

from where does one wipe the ext partition of sd?

[Guest leetLegend]

Notice that you DONT need to sign an update to apply in the recovery....

Nice Koush :)

waiting for "adb shell" to make my life a little easier :]

You can adb shell into CW recovery.

Maybe try formatting the FAT partition?

[Guest Loccy]

This is excellent work! One thing though, can I please ask you to keep plugging away at the EXT issue? I for one have no intention of ever using Froyo's A2SD, as it's a pile of shite, and intend to retain my EXT partition for apps. So without EXT support the usefulness of this is limited for me.

Tried already, getting :

- exec '/system/bin/sh' failed: No such file or directory (2) -

Will try! I hope it's the FAT partition only...

[Guest Koush]

Tried already, getting :

Oh, I have a fix for that. I'll provide a fix later. Adding RM support now.

[Guest GeoTrail]

When the recovery starts, it prints out:

E:Can't open /cache/recovery/command

When I run the Apply sdcard:update.zip I get the follow errors:

E:failed to verify whole-file signature

E:signatur verification failed

Installation aborted.

I have updated my device to the latest OTA update, including the 0.80 HB.

Any ideas?

[Guest StuMcBill]

Sorry if I am being dumb, but what's RM support?

This is great work, thanks for this guys!

[Guest xTc is loVe]

Will there follow Updates? Only need nandroid+adb+EXT WIPE =)

[Guest fxone]

Sorry if I am being dumb, but what's RM support?

This is great work, thanks for this guys!

i Think Rommanager but im not sure

[Guest StuMcBill]

i Think Rommanager but im not sure

Ah that makes sense. Doh. Ha ha :-)

[Guest daverave999]

Thanks both. Works as expected!

[Guest jcdz92]

Hi,

Everything worked as they should , copied the latest update, did a nandroid backup, md5 ok; But when I tried to apply a custom rom zip, what CW recovery showed me from my sd card was every folder but no zip (I have 7 zips in there update included)

Anybody have an idea , I'm running Froyo on my Desire and sd card is only FAT, don't use A2SD

Thanks

[Guest jdouce]

i got RM paid ... but everything is greyed out..

[Guest Jase Winter]

How do you wipe dalvik cache with this new method? Thanks!

[Guest spammyspam]

The test image was what you flashed during step 1 of the rooting process.

Okay, but what is it? And does it still exist after you flash with an MCR or rooted ROM?

Perhaps this isn't the right thread for this?

[Guest timothydonohue]

uh, how are those of us in the colonies that happen to use evos supposed to select anything?

without a trackball/pad, all pressing power does is turn the screen off

If your referring to this particualr Recovery menu then your in the wrong section my friend because this is only for the Desire/Legend. I can only assume a recovery image for EVO will most likely make use of one of the buttons you DO have (or will change the funtionality of your power button).

Awesome work Paul and Koush. The transcript made for interesting reading too, seeing how these things come together from you amazing devs!

Keep up the good work guys, its so appreciated by the community... and its amusing to see HTC trying their best to lockdown rooting (WHY?!) and you guys just ripping it apart. Love it :)
