Hello,
My friend has an LG Optimus 3D running stock froyo which i rooted for him and installed ClockworkMod Touch Recovery 5.8.1.5. Everything was fine until a notification for an upgrade to gingerbread was available and he clicked install.
Now the phone can only boot into recovery. I tried to restore a previous backup, flash the zip of a froyo rom. But to no avail.
Any idea what might be cause and solution?
Thanks in advance
UPDATE: I connected to adb and gave the command "adb reboot-bootloader" and it still boots into recovery. Is it normal?
UPDATE 1: I tried using the LGMobileUpdate tool to install the update in the hope that it solved the problem, it detects the phone, downloads and extracts the rom, start the update process and then gives a connection error. The error isn't given during the detecting phone phase but when it start to apply the update.
Bump... Please, anyone?
Try flashing an entire ROM. The kernel may be botched.

Thanks for your reply
I have already tried to install through clockworkmod the zip of the stock froyo rom (from the thread of official roms). Nothing changes. Neither restoring a backup from clockworkmod changed anything.
As I remember that the kernel is part of the rom zip, I think the problem is more low level.
Tomorrow I'll try doing this http://forum.xda-developers.com/showthread.php?t=1244490
Any other suggestions or ideas?
UPDATE: Followed the guide here http://forum.xda-developers.com/showthread.php?t=1540163 and managed to flash the kdz of v21a. Problems solved

try installing stock rom with lg app then reroot and install custom rom
Sent from my LG-P920 using xda premium
hello everyone.
m new to this world of rooting & all
i already successfully rooted my lg p690 & want to install recovery image to make a nandroid backup,
plz guide me how to proceed...
thanks
The easiest way, though somewhat dangerous, is to install ROM Manager from the Play store. Do not attempt a backup! Though it works fine for many devices, some devices are bricked by attempting a backup through ROM Manager.
Use it to install custom recovery, then exit the app.
Alternatively, if you have the .img or .zip file of the specific recovery you want to install, use Android Flash Recovery through your computer. It's safer, but you have to download the custom recovery image yourself.

for root you must flashe bootloader and twrp with os_hacking 1.25 tool
1-ics bootloader
2-GBtwrp
3-Su_Bbox_1.20.2_gazhead_signed flashe this zip withe recovery mode and you get acces root

I think but not 100% sure that once you root and install cwm you can reflash original bootloader again.

I am almost sure, plus I think I read about it somewhere.
GUYS:
You can flash custom bootloaders, flash recovery, root from recovery and reflash stock bootloaders and kernel afterwards, using xbsall's rebooter tool (if you want it, search it in his v8 rom thread).
OR (and this is better if you want to keep it stock)
You can root using 2nd init recovery, without changing stock bootloaders and kernel.
Just install 2nd init recovery with the attached P940RecoveryInstaller (Thanks to Milaq) (just put in sd card and install it).
Enter 2nd init recovery by pressing VolDown while booting or by pressing key inside the program.
NOTE: flash the attached Root_P920_ICS from recovery to root.

That's odd, never had any error while installing it, and also xbsall uses it in his roms...
In what rom are you?
Try to install it after rebooting the phone.
I have root ics v30a by these steps:
1/ flash wpark v1.25 bootloader
2/ flash twrp recovery (step 1 and 2 by all in one tool)
3/ flash super user by twrp
4/ flash back ics stock bootloader and done
For me now i think i have stock and rooted v30a.
All thinks for 4 steps above can be found in this forum ( all in one tool topic and noob guide for xbsall topic)
Im not sure but when i come from ics port from su760 to stock p920 ics, my touch screen has problems (i have a dead spot that cant touch able at bottom right corner). And flashing freroot v28b from xbsall may be the cause. After a week try to test its hardware or software problem ive found it.
Now i solve touch screen problem by these steps:
1/ flash v21e stock bin posted by xbsall guide and attached.
2/ setup complete stock v21e and make a back up.
3/ flash v30a stock and root as above and the stock screen problem are gone.
I dont know why but if i skip step 2 and flash v30a inmediately and the touch screen problems still there

about the second one, did you mean we can install a recovery without rooting the phone? that's never happen before, are you sure this would works?

Well...
Actually you're right.
You must root before installing the 2nd init recovery.
This recovery will, however, allow you to keep stock boot and kernel.

Be careful.
When I reverted to the ICS stock bootloader I ended up with LG Security Error (and had to flash back the wkparks 1.25a boot & cwm recovery !)
If you want custom ROM you need custom bootloader.
You MIGHT be OK with stock boot if staying on stock (rooted) ROM...

No, that's not it.
You may have custom rom with stock bootloaders, that's ok.
What's incompatible is stock bootloaders with custom kernels.
You got that security error because you had custom kernel installed.
So, the option is:
1. stock bootloaders and stock kernel
2. if you want custom kernel, you must flash modified bootloaders.
Well...80% of custom ROM's have custom kernels these days or/and require modified bootloaders...
Used all in one tool and flashed ics bootloader and gingerbread twrp. all good. flashed su root.zip from recovery[twrp]. allgood flashed ics stock bootloader. all good BUT cannot get into twrp recovery by using vol+ and 3D and power on. Has flashing stock bootloader wiped the twrp recovery? Or has the method of getting into recovery been altered by the stock bootloader.
Many thanks, KW

Stock bootloaders include stock recovery.
If you want custom recovery (twrp or cwm) you must flash again modified bootloaders.

Well, actually most of the existing custom roms come in zip (flashable in recovery) format, and those don't include any bootloaders or kernels.
Only bin or kdz roms come with bootloaders and kernel (for example, xbsall's pre-rooted bins).
Hi there,
After gaining Root access (SuperOneClick) and istalling Rom Manager I flashed a custum ROM (installed from SD Card) on LP optimus One P500 (Android 2.2.1). Rom was supposed to get me to android 4.1

Did you do a complete clear or did you skip some steps? What recovery program are you using - can you boot back into it (using the alternative methods), clear everything and try again? Are you sure the ROM you picked is the right one for your phone? You might have to use the LG tool to flash it back to stock and start over. However since you are getting to the boot animation (and you did give it a good 15 to 20 minutes before declaring an issue I hope as some ROMS can be really slow setting up for the first time) it isn't completely bricked. Keep hunting here and you will likely find a resolution.
to be able to revive you phone you need to instal a recovery, witch I see you didn't and tried to instal a custom rom without it directly from RomManager, one thing, RomManager isn't compatible anymore with p500 so that made your phone softbrick
step 1. go here http://forum.xda-developers.com/showthread.php?t=1827723 download the tool read all abouth it, flash recovery on your phone (press THANKS to THE MAN)
step 2. find a rom in development section an flash it via recovery
step 3. boot phone
step zeo read all FAQ and sticky threads to avoid further problems

Hey there. I have a big problem with my LG P920. I've rooted it, and flashed CWM With Rom Manager on it. When I made a backup, I have some problems as it has got stuck on the LG Logo on start up. I fixed it anyhow, so I tried installing the Rom now. When I rebooted into CWM Recovery, it gets stuck at the LG Logo again.. Any tips ? Thanks !
(wanted to flash ICS! )
are you on GB or ICS in any case you probably need WKparts bootloader so go and install that first if you want to flash ICS from GB do you need to follow this Guide https://www.youtube.com/watch?v=FqC5qw6WRaY&feature=youtube_gdata_player
Im on Android 2.3.3 or something haha.
Edit : That Guide doesnt work for me as "Ports" aren't showing up for me at Device Manager.
