Hi, I rooted my Froyo 2.2 Optimus One (LG-P500) with z4root (http://xdaforums.com/showthread.php?t=833953) then I installed CWM with ROM manager.
I installed CM11 v.12 (http://xdaforums.com/showthread.php?t=2589303) following AROMA installer steps; I rebooted my phone and I saw this:

I read this guide to unbrick the phone (http://xdaforums.com/showthread.php?t=1088046&page=9) but it seems for people that have bricked their recovery while I can correctly run it. Have I to follow this guide anyway? Then? Where I'm wrong?

Thank you all!

Still can run recovery? Did you do a backup before attempting any of this? If so, restore it. If not, well, live and learn :(

Recovery is ok

As I wrote, recovery is working fine; unfortunately, I have no backup.

EDIT: I tried flashing CM11-v.11, no way. Is the problem what I flash? Or it's nothing to do about it? (I'm thinking about flashing stock rom)

Can certainly try it. Newer ROMs do work better than this, however. If you were on Froyo, you will need the old baseband fix for any of these ROMs. It's OK, I use it myself.

Note that for KitKat, you need the newer recovery Clockwork 6.0.4.8. For others, the older 6.0.2.7, etc.
Maybe get your phone working again with that backkup before trying any other ROMs.

OK thanks! I notice now that ROM manager installed me a 5.0.2.0 CWM recovery! Is this the problem?
How can I upgrade it?

Regards

brick

I flashed CWMod-6.0.4.8-June04 "img" file (taken here "http://xdaforums.com/showthread.php?t=2564767") through the command "fastboot flash recovery recovery.img" in fastboot mode, and now it's a total brick (black screen).
I'm not really lucky :(

EDIT = i can't enter fastboot mode neither. I'm not sure if it's because the back button is faulty (that is true but I succeded the first time) or even fastboot mode is broken (is it possible?)

Looking for a new phone, thanks all :(

You can get these phones dirt cheep in some places now.

Last try.
Take out battery, press home/volume-down/power, replacing battery. Or variations of this scheme. Since I have never succeded in running fastboot, this is how I got my phone back after similar mishaps. Try several times. (Make sure you have charge on that battery because that will to it as well!)

I flashed that image from adb shell: flash_image recover /sdcard/....img. There is also a normal zipped version that can be flashed from whatever recovery you have up, but not recommended. Using the adb method, if it fails, one can IMMEDIATELY flash an img that is known to work and not be bricked!

is this the recovery combination? I tried but I'll try again.

where I was wrong?

are you talking about flashing a recovery with a recovery? why it's not recommended?

sorry, I don't understand this part.

Yes, but more physical action. Sometimes manipulating the battery can get back into recovery. Cost nothing to try.

If the flash that recovery zip (overwriting the current one) and this fails. Brick.
If I am alive in adb and I flash_image the recovery .img and it fails, I now have no valid recovery but am still alive, and can then flash_image another that is known to succeed..

Problem is that our phones are restricted to a 5 meg recovery section. The dev worked hard to get the new CWM small enough (taking out some functionality such as partioning sdcards to do so), but it is right on the line. On some phones, unluckily maybe yours, it doesn't quite fit on. There is also a new TWRP recovery around, same restriction but maybe would be OK.

I flashed the recovery that bricked the phone exactly through fastboot shell with the command above. So where I was wrong? :(
Is it possible I've "bricked" fastboot mode too? Or I can't enter fastboot anymore just because my back button is faulty?

thanks!!!

I have never succeded in getting fastboot from my PC. Did it in an adb shell session (which means android or recovery was alive and kicking).

What messages did you see on the flash_image? Any error? Did it fit?

From the adb shell, if the flash_image fails, I can flash another img which I know is OK (must have that around on the sdcard). Then, no harm done. Otherwise, it is possible that the flash over-wrote the existing recovery, but failed. Thar's the problem.

recovery

When I flashed recovery from fastboot shell, everything was ok and no errors showed up.
From that moment, screen is always black.
