[Q] G2x stuck at LG logo/cannot access recovery

Hey all
Before anyone mentions that i should be searching around more, i would like to say that i've been on multiple threads and they all state the same thing (use NVflash to flash CWM and then boot into CWM but the solution did not work for me past flashing CWM and then trying to access recovery after) and i wasn't able to find one that had a similar problem as mine.
I have CWM flashed through NVflash and was running CM7.1 RC1. I took a screenshot with the 'shootme' app and proceeded to look at the gallery to make sure it came out okay. The gallery crashed and i was sent to the home screen. I swiped to a different homescreen when my phone froze halfway through the transition to the next screen. No combination of buttons/long presses were able to get me out of it so i went ahead and did a battery pull. So my dilemma is that now i'm stuck at the LG boot logo with no blue status bar under it. It freezes there and will not do anything every time i boot up. volume down+power does not give me access to recovery nor does any other button combo get me past the LG boot logo.
Are there any other methods i might be able to use like ADB or what not to get myself out of this situation? or at least into recovery? Any comments or suggestions would be greatly appreciated as i've been searching for hours with little help and my eyes are starting to get strained.

hmmm.. I know it's a simple question, but I gotta ask.. are you holding the pwr and volume down button long enough? you have to keep holding it even after you see the LG screen.. Keep holding until you see the 2nd screen?
If so.. do the nvflash again? Edit: Not sure if I would do this without getting further guidance tho..

This. I remember when I boot looped my phone I had the problem of letting go of the volume key too early, you need to hold down volume and power from a totally powered off phone until recovery actually starts and you see the green "android" logo of CWM.
Try re-flashing CWM, NVFlash CAN fail. There is literally nothing you can do within the OS that will prevent recovery from working. Either you did something wrong somewhere along the recovery process or you discovered an entirely new problem with the phone. I'm going to hazard a guess and say it's the former.

Thanks for the response guys. I wish that it was the case of not holding the buttons long enough. I have tried numerous times with the buttons held down for a long period of time. I even held the combo down for almost 5 minutes a few times.
Every time i try to boot up, it won't go past the LG boot screen so i would pull the battery out and go through flashing CWM through NVflash again. I'm sure I'm not missing anything because everything goes through and gets sent to the phone successfully.
I did happen to run into a thread that was closely similar to mine but his method was to just keep reflashing CWM and the stock recovery back and forth every time it failed until it turned on. I might have to try that if i cannot figure out this problem out soon. Not being able to use this phone is killing me! heh.

I just joined your club. Wow this sucks.

So apparently this is a whole new problem that's been found? Every other help thread seems to point to using NVflash or remaking the partitions due to a bad flash using an O2x based file instead of G2x.
But none of those solutions come close to doing anything. There has been some people with the same problem as me but aren't proactive at all enough to get someone's attention, so i'm guessing this problem is getting pushed to the side with people just going about getting their phones replaces/buying new ones.
I did happen to run into a thread on paulobrien/modaco's forum that had people using NVflash to get out of any sticky situation like this. It just reverts everything back to the stock factory settings but with root. We cannot use this though because he hasn't built it to be compatible with our LGP999's because everything was built for their UK LGP990's. Maybe that's a start to getting this solution fixed?

I hate to say this, bit you might have to call t mobile and get a replacement. Flash back to stock recovery and they won't know you messed with anything.

Don't send back....you'll get same defacement a battery pull go into nvflah and go back stock then flash nv flash fix pArtitions

As I have mentioned before, NVflash does NOT give me access to my recovery let alone solve anything else. NVflash DOES work and does sucessfully send both CWM and the stock recovery but when I try to boot into either of them, let alone just power on normally, it simply DOES NOT go past the LG boot screen. it just hangs there doing nothing at all until I pull the battery out and do the same process over until it just hangs again.
while it is on/stuck at the LG screen, my computer does not recognize it so i cannot even try and run ADB commands. It does however, recognize it when I plug it in using the volume buttons held down when I use NVflash but there's nothing else I can do besides use NVflash obviously.

Did you ever find a solution to this issue? Because my phone is doing this...
I attempted to restore my phone back to the wrong backup that was from a galaxy sII (2.3.4 i think); needless to say, the restore failed. I then restarted my phone from CWM and it gets stuck at LG screen.
I have tried to NVflash back to stock; nothing. same thing reflashing back to CWM.
ideas?

have you tried this link out yet?

same problem..... anybody find something to fix this yet?

From what I heard is that you need to remove the battery, then boot into recovery or something.

Use smartflash for the p990 but only use the p999 ap.bin file which will put the rom and kernel back to stock p999.

Rom for recovery always fixes any soft brick back to stock 2.3.3 OTA. It's saved my phone multiple times from stuck on S/W screen to being stuck on lg logo or even the dreaded can't mount sdcard-cache errors in cwm.

I used the following method when Clockworkmod became corrupted and was unable to mount my sd card. I had just wiped everything on my phone intending to install a new rom when the issue happened. I could not even get to the S/W upgrade screen. It saved my phone. Hope it works for you.

Glad for you that it worked.
Kwes1020 pointed me in the right direction last week. Be sure to give a thanks to ILUHA_89 who came up with the fix.

Amazing how people are soo lost without providing them link after link to other threads. They are soo lazy and can't follow simple directions, each time i get a new phone i go to that section on xda and soak up all the information as it usually is already there. It's just funny is all i guess.

It's really not that big a deal. I was brand new to android once and asked all sorts of things.
I, like you, happen to read everything I can get my hands on. Some struggle going through all the info. I was here the day the forum opened, so I kind of remember where everything is.
Some are lazy and others just have no idea what the heck is going on and are intimidated by certain processes. I would rather help someone instead of listening to them ***** about their broken phone.

[Q] Can't get blue recovery screen to load up

I have been running on the gb 2.3.3 rom (rooted) that I have flashed using odin back in summer and now decided to do some more upgrading . So I found a new rom that was very intriguing to me: http://forum.xda-developers.com/showthread.php?t=1305145 After doing some research I realized I needed to do a different type of flashing (cwm?), and not through odin. So I downloaded root explorer into my phone and followed the procedures in this forum: http://forum.xda-developers.com/showthread.php?t=1122508 but every time I try to put my phone in the recovery mode (holding volume up + down + power) it wouldn't go into the blue screen. Instead, it would just restart, and restart, etc.. Any suggestions? Do I need to do something with the kernels?
p.s.hahah after messing around and looking through forums all day, I got a little impatient and flashed gb 2.3.6 using odin in the mean time

Try this.
Basically do what youre doing but instead of keeping on holding to it, hold on to Volup+voldown+power for 2 reboots, then on the 3rd reboot, the gs4g screen in the beginning lights up a slight lighter than usual. Let go of the power button, See if this works.

Download the Odin KJ1 version.

Just making a quick check. You ARE using a galaxy s 4g right? if so, then from that link, download the kg4.tar from the odin section. Then flash via odin. .

Hi I have the same problem but I still cant get into recovery, I go straight into Download mode. Please Help

It might be because your phone is connected to the computer? If so, try disconnecting it

This thread says the original GB rom changed the key mapping. Any ideas on where I can find a fix. I think thats what happened to me.

hmm I'm still relativley new to this kind of stuff as well, so the only route I know that you can do that will most likley fix the problem is to odin to a newer rom, perhaps the one I have linked above, then odin the kernal as well to get it rooted and follow the guide on how to do it if you're confused. Then turn off your phone, hold (volume up + volume down + power), screen should boot up then dissapear, boot up again, then disappear, and on the third boot up, just release the power button but continue holding on to the volume up + volume down buttons and just wait. The cwm screen should come up from what I experienced on two different sgs4g's. Hope that helps somewhat lol. I'm sure there might be a easier way to just fix the key mapping but I'm not to sure on how to do it. gl

I just verified that method works for me as well. I'm lazy, though, and downloaded Quick Boot from the app store as it lets you boot into recovery or download mode. Less fuss.

[Q] Bricked or maybe Soft brick (bootloops help) sorry its a lengthy explanation

LOL same thing happened to me, except i was flashing a tw4 file that was meant for a GS2 (idiotic). Try holding the up volume button and power until the screen goes off, or pull the battery. Then hold both volume rockers and power until samsung screen comes. Hold it like one second after, should work. Then probably restoring from in cwm is best bet, there are no kernels that are made for infuse on cm7. Sorry, if you recently made a backup then restore the phone then do that. Make backups often, incase stupid decisions like this happens lol. If you can not even get into cwm, then this is your friend. http://forum.xda-developers.com/showthread.php?t=1116251
EDIT: O wait, if cwm does work, then contact linux bozo over on compiled cm7, he may be able to provide you with a cwm flashable kernel.

Ok...you cannot flash any kernel...(infusion,entropy...ect...ect) with cm7 or miui ...the have their own kernel compatible with that build...and if u look in cyanogenmod settings in settings/cyanigenmod settings/performance....it has its own governor and can be overclocked or underclocked from there...really don't need another kernel with cm7...

Bricked from odin tutorial!!!!

Hello all! Im new here, but have been using alot of the tutorials and mods. I recently decided to move from FROYO to ICS, using several tutorials, but didnt even make it to gingerbread I was using this tutorial http://forum.xda-developers.com/showthread.php?t=1705260 and at first when I ran odin, all was well, except it wouldnt boot past the ATT splash screen, and it also had the 'rainbow' screen before the samsung loading screen, so i followed this :
2.) I have rainbow distortion in recovery or in the boot animation. How can I get Gingerbread bootloaders to fix this?:
If you have rainbow distortion, you still have Froyo bootloaders. You can download THIS .rar file, extract using 7zip, and flash the tar.md5 package in Odin (use the pda slot). Flashing Gingerbread bootloaders will correct rainbow distortion in recovery and in the boot animation. Only flash these if you are having issues with rainbow distortion, and only if you have had success flashing other, less dangerous items in Odin.
After re flashing with odin, my phone will no longer turn on... at all. Ive tried getting it to go into download mode, tried using the three button recovery, and nothing. Is there anyone that could help with this!? If i cant figure it out, I might not be on the infuse forums much longer... lol

Rainbows only appear on ics or above, so if you saw rainbows, you must have flashed ics.
As the warning said, a failed bootloader flash would leave you with a brick. Did odin stop during the flash or did it say it completed succesfully?
You may try using a jig and see if that forces download mode, but i doubt you will get results from that.

The new bootloader I loaded was supposed to be a gingerbread bootloader, and it said that if I saw the rainbow screen it was becuase i had the froyo bootloader, as quoted above. Ive read in alot of different forums, and ive tried charging it, removing the battery for 10 minutes and trying to get it into d/l mode, but nothing works. I think i may just have to chalk this one up as a very mislead failure. When I used odin, it said it was completed successfully as well... Im pretty sure that the 'gingerbread bootloader' is just a bad file.

As Andros11 said, you might try using a jig, for me it would be worth the $2. price to give it a try. If it does not work there are unbrick services available for about $50.00- not too bad, considering.

Go back to that page DL the one unbrick root 1.1 flash in Odin,
http://forum.xda-developers.com/showthread.php?t=1613523
Toto that link DL the cwm with root extras then as soon as you are done flashing the first one reboot for good measure, shut it off go into download mode flash that giving you a cwm recovery, somewhere in that post I seen gingerbread loader a link maybe getting you to them, I flashed to gingerbread bootloaders, forget where I got them off xda, then flash a cm9 rom taking you to ics, somehow in that process my rainbow screen went away and I have not had that problem every since.
I did have a small problem with Odin hanging on do not turn off and it just sits there. I got tired of waiting over five minutes nothing happening, I unplugged it, pulled battery, then when I went to download mode I had that rainbow screen, but not to worry it is still in download mode, with my infuse, I has to toggle the volume button up, after it sets to the first screen then you are in complete DL mode, check Odin to be sure you got that yellow check box to be sure it sees the phone then do the flash again, the BIG TRICK HERE IS, before you maybe find the rainbow screen in DL MODE, after you pull the USB cable pull the battery, replace the battery, then turn on the phone and let it hang up in what ever screen, then pull the battery again to turn it off, replace the battery then go into download mode, and the flash will take off and only be a few minutes. That worked for me more then once. Hope that helps,

[Q] Rooted Froyo to Frozen Galaxy S 9I000 after a flash with SGS Kernel Flasher

I have like many, played with my Android for 2 years now. I have a bricked Infuse GB (finally toyed with it to its death last week), so I pulled out my old Froyo unrooted backup. I rooted with SuperOneClick - easy. I made some kernel tweaks in Rom Toolbox Pro, and also changed a few status bar icons. I did several reboots and all was running well. I did need to adjust some more tweaks but I saved those for my next big change, when I decided to.
...look into more of what I could do and downloaded the zip file for Voodoo Sound. I read that this could do wonders on my Froyo stock rom and was compatible - actually, I read fairly safe. So I can't say if this caused this or not. It could have been my lack of booting after each simple change, font, notification icons..etc. But I didn't do much more before I flashed Voodoo Sound
I downloaded SGS Kernal Flasher from the market, and when I flashed and it booted, I got the SAMSUNG screen. Then followed by a new black screen with GALAXY S GT-I9000 in white with Samsung logo on bottom. And it stays frozen. I cannot enter recovery mode or download mode to my knowledge - or should I say, experience.
Since this was my backup and what I was doing seemed relatively harmless Im a bit shocked. I loved that my font and icons were changing, something I couldn't do with my gingerbread infuse using rom toolbox pro.
So now I am stuck on a bootscreen I've never seen before, nor intended to flash if that is what happened. Was this flashing Voodoo Sound or was it my negligence with other? I just rooted this yesterday after getting too frustrated to fix the GB. I don't think I had but 4 apps downloaded and really left most of the build.prop stuff alone beyond some minor adjustments for battery life.
So I'm stuck on a boot screen with a phone model I am not familiar with, cannot get into download mode or into recovery mode. I had a TWRP Recovery zip file I never set up yet, never got CWM recovery working - regardless, I just started playing with it so I'm lost as I thought I could just wipe, reinstall packages and reboot fresh. I hate this to be my first post, but I usually find all the answers I need from you guys and I appreciate all the efforts you put into this site to help noobs like myself from creating disasters. I just didn't know what to do and if I'm not hard bricked, I don't want to end up that way.
I thought unrooting would work, but I can't get into the phone so it won't connect to the computer. Also, when plugged in, it shows a battery frozen at zero. I know it's probably charging but that must mean I messed up something that starts at boot. Anyone willing to help me resolve this issue and get me back on so I can make phone calls again - something I should probably stick too, haha. But sometimes, mistakes are the best teachers...so maybe I'll learn something easy from the pros here.

Well u have the wrong kernel flashed some how
I would try a different computer and go for the heimdall package to take phone back to stock.
As soon as you do get to download mode and I know it sucks with bad kernel flash I did before my self. Gotta just keep trying ..... If you got power u can get download mode.
For more information go to qkster thread ...

Thank you, I'll search that out. Well, I thought bricking was more potential, but if I can do a recovery on both that'd be great. I backed all up to laptop and gdrive before - and actually thought about leaving it "new". As my first root and tweaking, or "modding" out the GB was great. And I never picked Froyo back up, but I just wiped it and rooted it yesterday, and I only used it for a month when I got it (long story with phone provider and a dent on the side (but I have two Infuses,Froy and GB)
But I am going to stay away from flashing. That got the GB...but since you brought up the power option. I thought they were toast. If it takes me a few days to learn, I'd do it in a heart beat - they both have power and that means I can get them both working. The GB has a PC on left, Phone on right and a triangle in middle. I didn't read into fixing that - which I thought would be tougher than grabbing my other. Maybe I can get both working and get some more insight.
I appreciate it, and anyone else who inputs. I'll start reading into that other thread after dinner, cross your fingers for me. :fingers-crossed:

I cannot find the specific thread you were directing me to. But I was successful after many attempts to enter download mode. It is being recognized but unable to access the insides of my phone. If I click reboot from download mode (volume down), it boots to the stuck Samsung logo. If I push up, it's in download mode, but I have nothing to send commands to it as it's not being recognized beyond the Samsung USB composite.
Can someone direct me to where the thread may be about the frozen/stuck Samsung boot logo? Also, frozen 0% battery level but charged all night.
I'm trying to find something specific on this but it's difficult being an Infuse Froyo and I'm stuck on the Galaxy S GTI900 which was never there before my last reboot - obviously whatever I flashed was probably for the Galaxy S. I get SAMSUNG, then the Galaxy S screen...can't seem to get into recovery because it's too fast before stuck again.

Take out the battery, put it back in do not turn it on hit volume up and volume down plug in USB that's the download mode you are looking for
