[Help] My o2x doenst boot, keep rebooting - LG Optimus 2x

Well, my o2x keeps rebooting, and stucking on boot.. i tryied flash v10b with nvflash and v20l with smartflash and its keep rebooting.. the phone doenst boot, i cant get into home screen.. anyone knows what can be? how i can fix it?
Thx

Have you come from a custom ROM before flashing v10b? If you have then you will probably have to use Paul obriens backtoext3 which is just flashed in cwm.
If its not then that's as far as my helpfulness can go...

i was on modaco, then i restore back the original backup with cwm.
after i tryied install v20l, phone doesnt boot, then i tryied v10b and phone doesnt boot..
now i cant install CWM since the android system doesnt up.. any other idea? maybe a backtoext3 without cwm?

You should still be able to get cwm even in a boot loop. Keep holding power and volume down until you get to it and then flash backtoext3.
Was it boot looping after you restored your original. If it was then you might only be able to nv flash an original rom.
If it wasn't then you should be able to get to recovery and flash backtoext3

Install CWM via NVFLash. Follow the first 3 steps of this guide to install it.

No. He said he smartflashed 20L, which means CWM has been overwritten with the stock recovery. All this will achieve is a wipe.

Yes, it does. I suggested you install CWM so you can restore a backup or flash a new one.
Both of the flashing procedures (NVFlash, Smartflash) should have restored your phone to a working state no matter what, so either your phone is faulty, or your USB-connection is flaky, lets hope its the last. (I assume you have read how, and most importantly, how not to connect USB when flashing.)
So run back2ext3, install a ROM and see if that works.

Primarily it was a hint to go search and read about how to flash before you flash. But since you ask:
Do not connect to USB via a hub, always connect directly to the computer. When something doesn't work, try a different cable. Do not use an overclocked computer to flash. etc. etc. etc.

Try to flash a rom or restore a backup via CWM. Doing the same thing over and over is not likely to help.
Download one of these: http://forum.xda-developers.com/showthread.php?t=1328656
Put it on your sdcard.
Install CWM via NVFLash. (If not already there.)
Start CWM.
Wipe/Factory reset.
Flash it.

Stock firmware problem after Cyanogenmod

A friend of mine suggested that I try Cyanogenmod, so I decided to flash my Galaxy Mini. The first problem was the bootloop, and no matter how many times I wiped the phone, it was always stuck at the Android text. So I decided to try the Honeycomb mod. Same happened. So I decided to flash it with Android 2.3.6 from sammobile.com. At last, it started working. However, Google Play still sees every application as "installed" (but of course they aren't), and when I try to delete from GP, nothing happens. After trying to install other applications, I realized that I cannot install anything from the market. Any idea how I could solve this problem? I would be very grateful.

Yes I did. I used CWM 5.0.2.6. The funny part is that after being turned off 3 times, Google Play started working But if there's a solution to the bootloop problem I would love to hear it. I searched this forum and the internet and nothing, even though I followed a cyanogenmod wiki's guide.
did you wipe two times before and after flashing cyanogenmod rom
How old is your sd card? because same happened to me. I needed to format my sd card.

No, I didn't see the sign, and to be honest, I didn't even know that there was a 5.0.2.8 version. Do you think it would work with that?

So I downloaded the new recovery, flashed it via Odin, and now nothing works. When I enter recovery it says that it can't mount /cache/log and /cache/recovery (I think it says these two). I looked around and found that it could be stuck in a bootloop, but luckily Android loads. However, I can't root my phone due to several errors, so I can't install Cyanogen mod. I think I'll give up now But thanks for all the help!

This happens because you are in stock ROM, this errors are normal.If you want ONLY to root your phone you should use stock recovery. Otherwise you can proceed.

Thanks very much Here is what I did step by step:
I returned to the stock recovery by installing the stock firmware. I rooted the phone with stock recovery. Then I installed CWM recovery 5.2.0.8, but I still get the same error in CWM: it can't mount a few things. I still tried installing Cyanogen without wiping, and of course it's stuck at the boot screen with the Android text (I had a feeling that it wouldn't work if the recovery is not fully operational, so I did not want to lose every contact for nothing again). I read that this problem can be solved by formatting the SDCard, so I tried formatting it with PC and the phone also, but nothing. So now I'm back to the stock firmware and recovery with my phone rooted and no idea how to solve any of the problems.

Flasging CyanogenMod without wipes? Seriously? Thats exactly why it never worked!! CWM cant mount somethings because you were in stock ROM
Use some backup program to backup contacts, apps, whatever and flash cyanogenmod wiping data and cache before and after.

This was just a trial run due to the new CWM recovery. If you read back, I already wrote that I tried wiping both data and cache before and after flashing Cyanogen mod. This "mounting" problem only came up with the new CWM recovery, 5.2.0.8.
The basic Google Apps were all there, since I used a rom from sammobile.com, downloaded programs like poweramp were the ones that did not work.

And you tried wipes using 5.2.0.8 version? The mounting problem happened with me only in this recovery too, maybe because it is updated, different or whatever but I flashed and everything was good. Anyway, stay with stock, it seems better for you.

[Help] Boot Loop everytime I go to recovery

here's the thing..
i'm running on v20g, i rooted it using LG extract and injected CWM, flashed it using smart flash. but everytime i go to Reboot to recovery i always end up on a boot loop.
will someone help me? is there any way to downgrade from v20g to v20o??
please help me, i'm unable to use my phone for about a week now. :crying: :crying: :crying:
try using smartflash.... works for me everytime... and also try flashing the normal cwm not the touch one... might help...

still boot loop.
Hey buddy! I have same problem with you! I noticed that when i'm on stock rooted rom i always ended into bootloop going into recovery using either rom manager or quickboot. When i'm on custom rom like marvel, zeus etc. i also ended into bootloop going into recovery but after 1 hr or more, i will turn on the phone and then it will boot into recovery. I have a hard time flashing different custom rom because of this. Its like there is a time out before entering cwm recovery. It also happened to me everytime i used smartflash tool. It takes an hour before my phone got boot. 2 weeks ago someone upload a flashable V20s spain stock rom that has capable of entering cwm recovery after flashing the stock rom and luckily i manage to save it to my computer. I flash it using smartflash tool, after flashing it will reboot and then it will stock into bootloop. I will remove the battery and wait for atleast 1 hr and then i will turn on my phone and it will automatically boot into recovery. I do data factory reset, clear cache 1st then install superuser zip and then after that i flash the custom rom. I suggest that look for a flashable stock rom that has capable of entering cwm automatically after flashing and once you got the cwm do all you want but install first the superuser zip before flashing custom rom.
EDIT:
Here's the link buddy but i don't know if its available to download.

To simplify things, you flash this using ClockWorkMod. It will replace your recovery to the default LG one, and your files (unrooted). As I have said, everything you need to know is in the OP (Original Post/er).
Since you are coming from Gingerbread (Zeus), that's all you need.

You said you're on Zeus ROM right? How did you flash it? You reboot to recovery (ClockWorkMod), make wipes, then flash the zip. Right?
Now download the file/ROM on that thread at post #22, save it to your SD Card. Reboot to recovery, wipe and flash it. It's just the same procedure when you flashed Zeus ROM.
You need not to be an expert. If you managed to flash Zeus, you can flash this too. There's no abracadabra involved.
Again:
Save the file from the thread
Save it on your SD card
Reboot to recovery either by long pressing power button (Zeus has reboot to recovery added), or go to market and download Quick Boot.
If you are in recovery, wipe data/cache/dalvik cache, so as to remove SuperUser files, and have a clean one.
Flash the zip you saved
Done? Reboot!

[Q] USB not working, just charging. Bricked or damaged by wiping system or data?

Hello guys, you're the only hope to fix this, I'm sure! I'm facing a very annoying issue, (I'm having an old BL) mine USB cable is not working properly (just charges the phone, and nothing more happens, all drivers are up - to-date. Strange bug, happened after few days while being on CM 10.1. I don't know if that is related but while using CM10.1 I used battery calibration app , tried to solve that long charging issue D) after using cm10.1 I have advance-wiped not only cache, dalvik, but also system, data , etc..then moved to 7.2 stable, still got no USB functions, computer just does not see my phone(tried 3 computers using windows 7 32/64 bit,Nvflash is also not seeing the device.) I wonder if someone could help me to fix that mess. Really would like to flash a stock rom, but nothing except charging is working. I forgot to mention that while being on Cm10.1 I used this http://forum.xda-developers.com/showthread.php?t=1800935 to mount storage, also some google mounting apps with no luck. CWM also does not mount mass storage. What could be wrong? Help will be appreciated ! :good:
If your cable is not working properly, only charge your phone, then there is no way to use nvflash, smartflash or cwm to copy rom to your internal sdcard. What you can do is that you buy a new cable or borrow one from your friends or from someone. If you have external sdcard then use a cardreader to copy rom to your phone.

If it is the cable what is broken just simply change to another cable. If it is the usb port itself on your phone then use sdcard to copy rom to your phone. There is no other option

Oh okay okay I got it now.
You were on old bootloader right? If so then I am uploading a backup of gingerbread v20s.
Do you remember what version of rom did you have before you flashed cm? So We could match up the baseband and the rom.
Do you want to replace cwm recovery with stock recovery?
What version of cwm do you have? It is essential to know, because backup formats are differs between cwm versions

Yeah, Im on an old bootloader, because lots of roms use this BL. I flashed Gb V20 d or e, i don't know now, because these days I'm not at home. Tomorrow will be able to look at my computer and tell you the exact version. Probably its v20d.for baltic countries.now just need to backup it, remove Root, clockworkmod and take a phone to warranty. Its the only way to do it. Very change how these chips go out. Confusing . after all, very thank you for your help!
*Okay, I watched the version which was flashed previously CM, it was BIN_LGP990AT-00-V20c-BAL-XXX-MAR-16-2012-0. I'm uploading it to the dropbox, it will take time, because of the DSL upload speed (76 kb/s). Can I ask you to make a backup of this ROM, using CWM 6.0.3.1 with a root? Here's the link, it might be uploaded after 3 or more hours. https://dl.dropboxusercontent.com/u/64768144/BIN_LGP990AT-00-V20c-BAL-XXX-MAR-16-2012-0.zip very thank you if you can !

[Q] [20a] stuck in cwm bootloop after installing 20b update

Hi,
i am stuck in a bootloop.
i have an unlocked bootloader and had CM10.1 previously.
i then went back to an old 20a backup i made some month ago.
that worked fine.
my phone downloaded an update to 20b then, and i installed it.
after that i am stuck in a bootloop now. normal booting gives me cwm.
i am not able to turn the phone off and charge it, as mentioned somewhere else, to clear the "boot to recovery" flag.
someone knows a way to clear this flag?
Its not important for me if i run stock or CM, but even when i install my CM backup now it still boots into recovery.
holding <down> while rebooting gives me "S/W Upgrade - Please wait while upgrading".
it seems the 20b update is still present and trying to boot into stock recovery, resulting in cwm getting loaded everytime.
(cwm works fine, i can upload a zip and execute it)
greetings

i had the same, if you want to install ota updates you should have the "original" recovery.
i flashed it back to stock with LG .kdz flasher. if i remember correct flashing a backup from sd card won't slove this problem.

hm, i remember having the same problem while installing CM. there was something i did to interrupt the loop, and yes, i think the original LG suite or kdz was involved. but i should not need to reflash the original rom.. its just a flag, i should be able to clear it with sideload/zip/button combination.
[edit] maybe i wasnt clear about that: i dont need the 20b upgrade, i would love to cancel the update process, if that makes my phone boot again.

sorry but i can't help you with the flag... i solved it by reflashing but i have to admit it's quite drastic.
well..
i will reflash stock i guess.
do you remember which thread/tool/drivers you used to reflash?
i am on win7 and my PC isnt able to load fastboot nor LG mobile usb drivers.
i have them installed but get the yellow warning on both in windows hardware administration page

Easiest way to reflash stock is to force an update using the LGMobile Support Tool. Once your phone is connected (I suggest the S/W Update mode) look for the option somewhere in the upper right menu.
Edit: This will also revert to the stock recovery.

if i recall correctly, the LGMobile Support Tool tool wont recognize my phone, since i have a custom kernel, unlocked bootloader and a custom ROM.
i am trying to flash stock ROM now with kdz updater ( http://forum.xda-developers.com/showthread.php?t=2069723 ), and if this does not work i am going through every method thats there..
total overkill for a working phone thats just too stupid to boot the right option..
@moneyvirus: thx

Not sure about this, but the S/W mode might make a difference here. No harm in trying, right?
well. i was able to install stock 20a with kdz updater and link above.
cwm is gone now ofc, but everything at least works.
in some hours i will be rooted and cwm'ed again, but well... its always the same lesson: never touch a running system.
but maybe here's the wrong place to insist on this wisdom
