I just flashed the .KDZ for v20c to replace v21d. Everything looks like it worked fine and says "LG Mobile Phone Software Update Completed." The phone rebooted and is now looping the Rogers logo. It stays on screen for maybe ten seconds, flashes, and shows the Rogers logo again. Rinse, repeat.
I had no issues going from V10 to V21d but something obviously went wrong here. Any ideas?

No need to do it twice. Just one should do the trick.

When I restart my phone it boots right into CW recovery. I tried to deodex but it didn't go through. Once in CW recovery I can hit restart and it loads up fine. Any reason this is happening or how to fix it?

Do this happen everytime... or just that one time when you tried to deodex??
I'm asking because the modded recovery is made so that if your phone never COMPLETELY boots... it will reboot to recovery the next time your phone restarts.
When it does restart COMPLETELY, it will restart as normal.. until it fails to boot again. (Which no one ever wishes to happen lol)
Hi everyone,
I have had Zeus 7.6 (GB based) for a long time, but the other day it started freezing a couple of times a day, and other weird things, so I thought: it's time to give ICS a go.
I then used SmartFlash Tool to install the latest official ICS for Spain... and there started my nightmare. Apparently the install went fine, but now every time the phone boots, I get the initial Android Install screen, which I can configure, but if I enter my google account, the phone goes crazy and I keep seeing warnings of processes crashing (even android.core or something like that). If I turn off my phone, and on again, it will get stuck in the LG logo. Then I remove battery, wait a while, turn on... and it boots again, but cannot do much.
I have tried doing hard reset using LG hidden menu, also from the Android settings did a reset, and everything seems to go well, but the 2nd time it boots, it always freezes in LG logo.
I have flashed Froyo, Gingerbread and ICS versions using smartflash tool, but no matter what, even when it seems to go ok, the version that always boots is ICS (after the software is upgraded, there is a reset of the phone, and LG logo again).
I have even tried recovery using the official LG mobile support tool.
Last thing I tried I read somewhere: I boot pressing Vol - and G button... and I only see a robot lying on the ground (scary!) with a warninig sign, can't get past it.
My guess is that something is corrupt, but I don't know how to do a full wipe without being able to go to recovery.
Can you suggest anything else to try? I'm really lost here and wouldn't want to be forced to buy a new phone yet!
Thanks so much in advance
If you have cwm backup of your 2.2 or 2.3 then you can try one more thing....install cwm patched 2.3 with sft and when it completes flash it will take you to cwm ...now directly restore your old cwm backup

If it still is zeus, simply keep pressing g key during boot and you should be able to get into recovery. Or is it always ics, that boots?
Sent from my LG-P970 using xda app-developers app
Yes, it's ICS (Spain version) that boots. I had it flashed after Zeus, and now no matter which ROM I flash, I have that ICS version (the flashing always goes fine, but when the phone reboots it hangs at LG logo)
Still trying to find a way to revive my little OB...
Thanks everyone for your suggestions!

It happens when you flash ICS....for me when I went back to 2.2 or 2.3 it failed to detect my internal memory....but as I always do a android backup. ...I flashed patched 2.3 and did a restore of my backup and my phone was all working again...that is why I suggested to use a backup if you have.

Not even this method worked? This is usually my "safety procedure", I always keep a v20s patched with CWM on my PC, to flash with SFT when something goes wrong. Then, when it ends, the phone reboots in recovery...

Hi,
My LG Optimus Black P970 is locked in boot loop and I can't fix it.
I did the whole procedure from this topic, until the last SFT screen with the message 'Download Complete' written in green. But the phone restarts and gets into boot loop again.
I tried to repair the phone with the LG Mobile Support Tool, but it didn't work either. In fact, after this last procedure the LG logo stopped appearing, now the screen just lights up (but does not show anything) and buttons LED blink.
What do I do?
Thank you
Initialization
Do yo turn off completely the phone and connect the usb cable without battery?

Thanks everyone for the replies. After several firmwares, I tried Europe V20S and it worked, at least partially. The boot loop is gone, but another problem appeared.
Now the screen is splitting into several. I think it might be a firmware conflict (for trying to install different firmwares repeatedly - do not know if I'm talking silly, noob here) and a wipe data / factory reset would help.
So I tried to follow this topic, since Optimus Black doesn't have a keycombination to get to Recoverymode on booting, but It didn't work.
Is there another way?
Thanks
hi!
i buy a used Optimus Black, now I have a problem, gets stuck in the boot logo amd blink lights, even after having used SmartFlash, someone will have an idea what to do?

Is it a patched v20 rom that you flashed? Flash again using SmartFlash and once the phone boots, it will take you to the CWM recovery screen and then do a factory reset and wipe Dalvik cache. Then reboot your phone and it will be just fine. BTW read the "Noob how to" section in the Q&A it helped me a lot.

The patched v20 bin/fls files should work for you. If not, try the hard reset unbricking method. You're welcome.

Issue: Phone suddenly shuts down, when trying to boot it, it just keeps restarting when hitting the bootanimation.
I use the phone less than 30 mins and suddenly it just shuts down and I have to do a full wipe for it to work again. Even after full wipe, it works perfectly fine for max 1 hour of use, then it shuts down and new wipe is required.
What I have tried:
Flashing PA, CM10.2, flashing full stock ICS V30A.kdz, repartion with AIO-Toolkit and even tried using Homero's ICS NvFlash version of ICS. Nothing helps, I use the phone a little, and then it just needs to be wiped again.
Anyone who had an issue similar to this? If not, then I think the O2X path ends here
Hoping someone can help.

Try to go back to old bootloader and use a GB rom and see if the problem persists. See the group on my signature on Facebook.

I tried using Homero V20S NvFlash ROM yes, which is on old bl, but it didn't help
After I use the phone like 1-2 hours maybe less, it just restarts and then won't boot again and I have to do full wipe again.
Yes psmax, I tried and sometimes, when I flash ROMs even in TWRP, the phone just shuts down in the middle of the flashing process. What the hell can be causing this?
Could it be an hardware problem?..

How can I know if its a hardware problem? That's what I am afraid of - because if it is, then its goodbye O2X
Sold the phone today.
Officially looking for a new phone now. Hmmmmmmm i wonder if i shall buy another o2x now that its being offered to me extremely cheap... i dunno what to do
Had almost same symptom: quick drop from fully charged to 60%, then random BSODs and reboots.
New battery did the trick for me.

A broken battery could send wrong readings to the kernel, which in turn responds with a shutdown or a crash. Most of the hw problems could depend on this...
