Waiting for bootloader

I'm having the same problem as ba11inncali in post 267.

Here's my details:

Installed AOSP Gingerbread v1.1.6 a few days ago. Ran fine, no problems, no random reboots or shutdowns. Haven't installed any new apps for about 24 hours. Last night I left the phone alone for a bit with GPS off and wifi on. I come back to find it really hot and dead. Figured I would let it charge overnight to see if it's alive in the morning. No go, still dead. Holding volume down and power at the same time with the battery in does nothing.

I've tried to flash it using NVFlash following the instructions. I installed the APX and the phone shows as "NVIDIA USB Boot-recovery driver for Mobile devices".

I've held both volume buttons down while plugging in the USB cable and then clicked the flash button (I've tried both the ClockworkMod and stock flashes). I've tried various USB cables which I know are good.

I've let the command window run while holding the up and down volume buttons for 30 minutes at one point (used a hand clamp, I didn't actually hold them) and it just sits at the following:

Any clues or suggestions? Is the phone truly and utterly bricked?
[T-Mobile LG G2x] vibrantcm7:
Waiting for the second LG to come up(blue one) the recovery menu came up...flashed to original and all is good. Thank you sooooo much :)
[T-Mobile LG G2x] TGA_Gunnman:
can you take it back to tmobile
[T-Mobile LG G2x] dsalac:
I'm going to try. Haven't a clue about what might make this irreversible. Oh well, live and learn.
[T-Mobile LG G2x] jthein1989:
Ok, since day one I have had no issues flashing any rom i decided to. Now, after the update, everytime I flash ANY rom, my screen locks up at boot? I have attempted every rom and every kernel available on this forums (for this phone, of course, lol). No matter what I do, I just get boot locked (made up that term). Unless I recover my "EB 1.0.2" I cannot boot? Any suggestions? May try to re-flash recovery here shortly?

Edit: A re-flash did the trick.
[T-Mobile LG G2x] TGA_Gunnman:
I'm just not ok with the fact you overheated. I'm thinkin that its a hardware/cooling issue with the device.

You might want to lay off overclocking for now with you new device (if you did it)

Id take it back vs try to fix, due to the nature of the failure.
[T-Mobile LG G2x] dsalac:
Thanks for the responses. I haven't done any overclocking on the phone (not since I fried a computer CPU way back when), so I really don't know what might have caused the phone to overheat. Maybe my dog sat on it and activated an unknown nuke function.
[T-Mobile LG G2x] jthein1989:
Ha, I need to find that function... I've dropped this phone like 4 times, and the insurance doesn't cover negligence... Lol
[T-Mobile LG G2x] TGA_Gunnman:
it does cover lost or stolen , hint hint
[T-Mobile LG G2x] jthein1989:
Nice, what is the deductible? I hate how bad my screen bleed is, and the fact that somehow there are two little black specs behind the glass (You can see them when the phone is powered down, therefor no dead pixels). Sorry for getting off topic.
[T-Mobile LG G2x] Prod1702:
the insurance does cover negligence. The insurance coers the phone if you drop it in water or drop it and break it. I know i sell the T-Mobile insurance everyday at work. you just have the pay the rate to replace the phone. Its just like car insurance. the deductible for the G2X is $130.
[T-Mobile LG G2x] jthein1989:
Thank you, I honestly didn't know that.
[T-Mobile LG G2x] soukie:
I have the same problem.
[T-Mobile LG G2x] Wildchld:
If you brick it T-Mobile will replace it. Hint free

E:Can't Mount /sdcard

Following instructions in OP. Seems to have worked. Rebooted into recovery via VOL DOWN + POWER get the red ClockworkMOD Recovery menu. However, when I try to flash a file I get the following error:

E:Can't Mount /sdcard

I flashed ClockWorkMod ExternelSD /ext4 option with the NVIDIA utility posted in OP. Anyone know what's up??

EDIT: Reflashed Recovery with INTERNAL SD/ext 4 option and it works. Duh...
[T-Mobile LG G2x] krylon360:
Do you have a external SD?
[T-Mobile LG G2x] petep86:
Thanks alot!!! YOUR THE MAN!
[T-Mobile LG G2x] TGA_Gunnman:
OP Updated with new CWM updates

Krylon360's Updates to CWM 3.1.0.1 (5-24-11):

ext4 support

Internal / External SD Support

Updated 2nd Boot Logo, now no longer Blue LG

Fixed USB Mass Storage option. Now mounts to the PC when selecting.

Reboot option is due to a kernel issue. Hopefully will be able to fix with the next update.
[T-Mobile LG G2x] TGA_Gunnman:
Just tested it and the SD mounts in CWM. Totally cool! This will save time. Thanks Krylon
[T-Mobile LG G2x] TGA_Gunnman:
known issue, its a kernel issue. We will all have to wait for the fix.
[T-Mobile LG G2x] tenbeau:
thank you for your kind and generous work. I just followed the op to the letter and here is what I have for results: I flashed to ext sd and when in rom manager I can only reboot to 3.0.2.7 when I have the phone off and hold volume down and power I get to the 3.1.0.1 Is this correct? Rom manger still does not see the backups I have made but when accessing recovery they show up, is this also correct?

thanks for any and all info:):)
[T-Mobile LG G2x] fcisco13:
So now we can select files to flash from internal if we nvflashed external version???

G2X
[T-Mobile LG G2x] TGA_Gunnman:
2.7 has some bugs but they are liveable. Test2 is more stable right now.
[T-Mobile LG G2x] tgerbracht:
Do I need to uninstall the rom manager cwr before I try this? Thanks.
[T-Mobile LG G2x] TGA_Gunnman:
No, go for it.
[T-Mobile LG G2x] shovelhead83:
I have windows xp 32bit. Anyway I can get a recovery to work?
[T-Mobile LG G2x] fcisco13:
Mine is 32 bit xp, got it done before the app (thanx allot, great work) got everything done in less than 5 minutes. The hardest part is installing nvflash, other than that it works flawless

G2X
[T-Mobile LG G2x] j0hnee:
Thanks for posting this but I have installed everything and when I try to install CWR it says "no USB device found" Any suggestions why Im getting this?? Please help
[T-Mobile LG G2x] TGA_Gunnman:
Go through the windows driver install step again. Do it correctly and you will be flying.

Sent from my T-Mobile G2x
[T-Mobile LG G2x] j0hnee:
so uninstall the driver and reinstall it??
[T-Mobile LG G2x] TGA_Gunnman:
If the driver is installled, try flashing again. You must hold both volume buttons down. Make sure you follow every step exactly.

Sent from my T-Mobile G2x
[T-Mobile LG G2x] j0hnee:
After I installed the driver I held both up/down buttons and I would get the no usb message. I just uninstalled the driver and Im going to reinstall it. ill post here with my results..
[T-Mobile LG G2x] j0hnee:
I just reinstalled everything and Im still getting the error.. Any ideas?? BTW my phone is in a bootloop if that helps..
[T-Mobile LG G2x] protechcertifiedrepair:
Thanks alot for this. I hadn't flashed with nv yet just cause I didn't have any roms to play with. But this makes it so easy I might as well with or with out Roms yet.

Thank YOU!
[T-Mobile LG G2x] swoleface:
Can you make a tutorial video for the noobs? PLEASE!
[T-Mobile LG G2x] C0dy:
It worked without a hitch for me. Thanks a lot!
[T-Mobile LG G2x] j0hnee:
Im not sure what to do .. Im stuck in a bootloop and I dont know what else to do..
[T-Mobile LG G2x] Waldano:
Thanks man :)
[T-Mobile LG G2x] TGA_Gunnman:
So you pull your battery. plug in usb. Push and hold volume up and down. Keeping them held down while you push the flash recovery button on the app. Still holding the volume buttons down?

Sent from my T-Mobile G2x
[T-Mobile LG G2x] j0hnee:
I pull my battery,I plug in my phone, I open oneclick recovery.exe, than I unplug my phone and then I hold volume up/down and click install CWR and I just get the "no usb device found" error.???
[T-Mobile LG G2x] TGA_Gunnman:
You have to hold the buttons down first. And keep them held. Then plug in usb still holding buttons down. Then push one click flash button on app while still holding down volume buttons. Keep them held until flash is completed.

Sent from my T-Mobile G2x
[T-Mobile LG G2x] TGA_Gunnman:
its in the op
[T-Mobile LG G2x] TGA_Gunnman:
no, now you can connect your phone to you pc. Got to mounts in recovery and turn on usb mass storage. Basically you can access your sd from your pc while in recovery.
[T-Mobile LG G2x] oophus:
Hey, I've got some problems.

I did my recovery with the ROM manager. And after some screwups, I tried to do a recovery which ended badly. My phone doesnt start up, its totally blank.

I tried to flash it from the guide you get on the CM forums.

I got the "S/W Upgrade" message there, so I guess I did everything right according to their guide. But the phone is still dead after that..

So now I found this thread, and I tried to do the steps here. Now when I press the OneClock exe file, I don't even get that "S/W Upgrade" message, and in the CMD panel I get the text saying:

Command failure: bootloader download failed (bad data)

bootloader status: Bct file not found (code: 21) message: flags: 107384014.

So does anyone have any tip for what I can try to do now? And yes, I followed the steps the video showed 100% as I did it 10 times or so.

Question though: Does this procedure only work with T-Mobile phones? I'm from Norway so I've bought this phone from somewhere else.

I've been trying to fix this now for 7-8 hours, so I'm starting to get a bit frustrating. I guess modding isn't my thing.. heh.
[T-Mobile LG G2x] TGA_Gunnman:
I thought there was one G2X and that is a T-Mobile phone?!?!? I dont know.

Soulds like the file E1108_Hynix_512MB_H8TBR00U0MLR-0DM_300MHz_final_emmc_x8.bct is missing from your nvflash directory.
[T-Mobile LG G2x] reisaru:
I'm guessing he's got the Optimus 2x, the G2x was only released in the US. Do you know if the images used by your utility have been tested on the O2x?
[T-Mobile LG G2x] ThC23:
Worked great thanks!

.....
[T-Mobile LG G2x] krylon360:
No. I would need to compile a recovery for the O2X. Recovery partitions are different in the G2x and O2x, same with Data partitions.
[T-Mobile LG G2x] reisaru:
I think we've determined the source of oophus' problem, then. ;)
[T-Mobile LG G2x] krylon360:
If you have the Optimus2x, Way to tell (top of screen, do you see LG or T-Mobile?) If you see LG, then you have a Optimus2x. Get Paul O'Brien's O2x Recovery Flasher.

It will flash the CWM for your phone.
[T-Mobile LG G2x] josemetallica:
multiupload is down someone have a mirror??

edit: never mind is up again
[T-Mobile LG G2x] TGA_Gunnman:
I figured since this is a G2x forum that X2 users would not attempt to flash. Yes as Krylon said, go with Paul's recovery.

Using this one will flash partition 5 which is not the correct partition that X2 uses.
[T-Mobile LG G2x] hire4blood:
I flashed a earlier version of this and now I try to update. I follow the tutorial and do the following:

Take battery out of phone

Add USB cable to PC

Hold Volume up and Volume down

Connect to PC

The PC does not detect the phone like it did when I flashed the first time. The phone is running EB1.04.

Any suggestions?
[T-Mobile LG G2x] TGA_Gunnman:
It should work like before. Can you try a different USB cable or computer.
[T-Mobile LG G2x] krylon360:
unplug the cable from both ends, and plug into PC, then vol up vol down plug into phone.

Happens to me about every other NVFlash... and I do a lot of NVFlashing. lol
[T-Mobile LG G2x] :
Hey guys, why wont my external sd card mount (i flashed the external sd support), is it because i need cyanogen? Im on stock btw... if i reboot to recov. through rom man. it works fine.... help?

EDIT: do i need ext 4 for this to work or should my sd card mount even if i have stock froyo?
[T-Mobile LG G2x] krylon360:
You answered your own question in this and didn't even know it. Delete the update.zip from your internalsd. Dont use Rom manager recovery options. Delete it from your external also if its there. Now, power down the phone, hold volume down and power till you see the new android logo then let go.
[T-Mobile LG G2x] flexnix:
I'm planning on going with the new CWM which offers ext4 today. Several questions though.

- One I install CWM w/ ext4 support does it automatically convert my file system to ext4 or is there an option in there to convert?

- Once I convert should I wipe everything and reinstall a new ROM or I don't have to re-flash a new rom, kernal, gapps, etc?

- Since I'll be in ext4 now can I flash back to Froyo Stock rooted in the near future. Reason I ask is because the GPS seems to be the best on it and I'm traveling soon. Or do I have to revert to ext3 then flash Froyo.

- Lastly, flashing the new CWM version. Do I go thru the same method with connecting it to the PC via USB, load program, flash, etc etc even though I already have 3.1.0.1? Or is there a different method if upgrading?

Thanks!
[T-Mobile LG G2x] TGA_Gunnman:
CWM just supports ext4 fs. It doesnt convert. You need a rom and kernel that will:

A: support ext4

B: convert your /data/app and /system to ext4.

This CWM just adds support for future performance tweeks.

The new CWM also adds the ability to turn on USB Mass Storage so you can access your SD card from your pc in recovery.
[T-Mobile LG G2x] hire4blood:
Again, thats what I'm doing:

Take battery out

Connect USB cable to PC

Hold Volume up + Volumen down on phone

Plug USB cable into phone

Nothing happens. I'm running ClockworkMod Recovery v3.0.2.7. I can boot into it via Power + VolumeDown without a problem. I tried different Computer and different USB cable. I also noticed when phone is on and I plug it into the computer it starts charging only...
[T-Mobile LG G2x] Kratz17:
TX!!! work perfect
[T-Mobile LG G2x] mannyg78:
When i boot into recovery and i navigate to the sim card to install a rom it says cant mount sd card. any suggestions? Please Help!
[T-Mobile LG G2x] mbh87:
Mine was doing this also, tried a different card and it worked. It must have to be formatted to fat32 (just a guess), try pulling everything off the card, formatting it in your phone and try again.
[T-Mobile LG G2x] mannyg78:
Thanks. Ill try that
[T-Mobile LG G2x] TGA_Gunnman:
how exactly are you navigating to your sim through recovery? what exact menu items are you selecting?

because ext-sd is for apps2sd ,etc....
[T-Mobile LG G2x] mannyg78:
I hold down the volume down and power button and it loads into recovery. Now the font is all red. It's v3.1.0.1. I scroll down to install zip from sdcard and then choose zip from sdcard and I get cant mount /sdcard. Ive already formatted my sdcard and still cant get it to read.
[T-Mobile LG G2x] hypmatize:
You might of installed the wrong recovery image... one is for the internal memory and the other is for the external sd card
[T-Mobile LG G2x] mannyg78:
I tried both and when i flash internal im able to scroll through the internal card. When i flash external thats when i get cant mount sd card. It's weird. I don't understand why it's not working.
[T-Mobile LG G2x] TGA_Gunnman:
did you install an external sd card?
[T-Mobile LG G2x] edward6790:
c

So i'm a n00b so please, be gentle :/

From my understanding, there was a release on 5/24 correct?

if so, we'll i've flahsed the previous version. How do i flash this one?

Thank you :)
[T-Mobile LG G2x] allbizzness:
Do you have extended warranty bundle... there's no deductible for warranty replacements......ie: screen bleeding ....
[T-Mobile LG G2x] schmit:
you flash it exactly the same way... by reading the instructions in the original post.
[T-Mobile LG G2x] mannyg78:
Yes I have a 16gb external SD card. When I plug my phone into my computer it comes up as F drive for internal and G drive for external. My computer and phone read the card fine its just in recovery where it doesn't pick up my external.
[T-Mobile LG G2x] TGA_Gunnman:
Just flash over it. Flash away
[T-Mobile LG G2x] TGA_Gunnman:
Did you try reformatting your sd
[T-Mobile LG G2x] mannyg78:
Yes. It doesn't allow me to do it from the phone though. For some reason that option isn't high lighted. I formatted it using fat 32 from the PC. Do I need to do it from the phone? If so how do I do it?
[T-Mobile LG G2x] TGA_Gunnman:
from the phone choose unmount then format is available
[T-Mobile LG G2x] Maisum:
Just did this today. Drivers installation was successful [when I plug in my phone via USB, it correctly detects the newly installed driver]. The cmd prompt window said successful, I hit enter to continue, gave it a minute, and unplugged. I

can

successfully boot into the recovery, but my phone is boot-looping whenever I try to turn it on. If I flash a custom ROM, will it fix this?

Btw, thanks! The recovery is looking good and very easy/helpful method!

EDIT - Suppose it does fix it, and I flash a custom ROM, would I lose all my apps/media etc. I didn't get a chance to back anything up and I do not have an external storage device on this phone.
[T-Mobile LG G2x] Maisum:
Fixed. Did a wipe and it took it out of the bootloop. Lost a lot of personal data though :(

Oh well, recovery looks great! Can't wait to try out some custom ROMS.

Thanks again.
[T-Mobile LG G2x] robecu123:
Hello, why is it that when i plug my phone into the computer, and click mount sd card it, unmounts my external sd card, then tells me to mount again this time its mounts but only my phone storge of mounting both, so i can't mount my external sd only the internal one. Thanks in advanced. and i did flash both options in the new cwm.
[T-Mobile LG G2x] N3xt2N0N3:
I can confirm this. I also have a 16gb SD card and ClockworkMod with ext 4 fixed USB Mass Storage doesn't mount my SD card. I reverted back to ClockworkMod 3.0.2.7
[T-Mobile LG G2x] mannyg78:
That worked. Formatted the card from my phone and booted into recovery and it read my external SD. Thanks for the help!
[T-Mobile LG G2x] TGA_Gunnman:
I can confirm this I too have a 16GB sdcard (an old class 2 at that) and mine works perfectly! :D
[T-Mobile LG G2x] LaNsLyDe:
My 16 GB microSD class 2 card is not detected by this recovery. Oh fooey
[T-Mobile LG G2x] TGA_Gunnman:
format it in the phone os
[T-Mobile LG G2x] hiko36:
edited out of existence.
[T-Mobile LG G2x] stormin4:
Huge thanks!

Thanks guys you saved my phone. This worked PERFECTLY after I couldn't get into recovery and my phone was endlessly looping with LG. Ya'll that developed this are very brilliant. Thanks again!:p;):D:D:D
[T-Mobile LG G2x] vn00914361:
I'm wondering when we can mount both internal and external sdcard ? Is it possible to mount both?
[T-Mobile LG G2x] g2xpolak:
Ok this worked for me finally.
[T-Mobile LG G2x] osugsxr:
Okay, just purchased this phone this morning. Find out that it is has been rooted and is currently stock. The recovery currently on here is 3.02.7, I am able to reboot into recovery from ROM manager, also from holding power button and down key. The "Reboot option" in recovery does work, it doesnt turn the phone off.

Should I go ahead and use the nvflasher? Or do I already have it?
[T-Mobile LG G2x] TGA_Gunnman:
Go ahead and flash over with the latest. Yes
[T-Mobile LG G2x] tq745:

There's no exe, to.install. you have to pull battery and unplug USB. Next hold power, volume up and down, then plug in USB without battery! Once your PC pics it up u may see failure to find driver. The way I direct my path is go to computer, right click and hit manage. Go to device's, and find the one that has a hello triangle, or may say apx! Next click it and hit update drivers, and direct your path to your extracted apx location. Should be it

@TGA_Gunnman:

I'm sorry for asking, but is there any possibility of you releasing something like this for linux?

NvFlasher is awesome but I really hate having to boot into windows just to use it. I'd really love some type of linux port, but it's cool if you cant. Just thought i'd put it out there

[T-Mobile LG G2x] :
ext4?

I have stock froyo build and when i flash the recovery it has a red font and doesnt find any sd card, i guess because its ext4, how can i make this work?
[T-Mobile LG G2x] TGA_Gunnman:
You really just don't have a clue, do ya?
[T-Mobile LG G2x] TGA_Gunnman:
OK ignore ext4 has nothing to do with seeing SD in recovery.

Next if you don't have a external SD that you bought then make sure you flash the internal version of cwm
[T-Mobile LG G2x] :
Lol i dont have a clue.... i have a sd and flashed external sd version. Does my sd card have to be partitioned?

Thanx for reply btw
[T-Mobile LG G2x] TGA_Gunnman:
No partition needed. Format it with your phone. In settings

Wow thanx bro worked!

Sorry i didnt read the earlier posts i need to develop a habit of that! But thanx for helping me nonetheless.
