[Q] fastboot - no boot or img file

hey guys i'm having some trouble. i just got the nexus (it's my first smartphone, ever) and i've tried to hit the ground running. here's what i've done to the phone so far.
i got all the drivers running on my win7 machine and also installed the android SDK folder onto C: as was described in this thread: http://forum.xda-developers.com/showthread.php?t=878786
i then unlocked the bootloader using the above guide as well. when I power on the phone using UP+POWER it says UNLOCKED.
I then proceeded to follow this guide: http://forum.xda-developers.com/showthread.php?t=875875
i used ADB to flash the clockwork crespo recovery. i then used fastboot to install Superuser.
at that point i had an unlocked bootloader, clockword recovery image and superuser permissions.
i then saw that the 2.3.1 update had been released. i wanted to learn how to tackle that so i started reading up. i noticed that people were using ROM Manager and Titanium. I got titanium and installed the BusyBox addon and it allowed me to do a full Batch Backup of all my programs, etc. i've got the 50MB or so backup folder on my PC now.
anyway, i then messed with Rom Manager. I installed the 3.0.0.0 ClockworkMod Recovery and everything went smoothly. now this is where my troubles begin.
when i go to Download ROM all i get is a Free Stuff area.
when i go to Check for ROM Updates it tells me my device isnt set up for OTA updates.
those are just minor issues.
this is the big and scary issue i have:
when i click on reboot to recovery, it takes me to the same screen that i go to when i power on with VOLUME UP+POWER. it doesnt take me to the recovery screen that i see in various youtube videos. instead, i'm at the main screen where it says UNLOCKED and i have 4 choices (reboot bootloader, recovery, reboot, power off). and on the very top in RED letters it says fastboot - no boot or img file. <-- this is the part that makes me nervous. If i manually power down the phone and boot to fastboot and click recovery, it just goes back to this same screen and says fastboot - no boot or img file. when i first rooted the phone, clicking recovery actually took me to a different screen where i was able to load up superuser.zip and install it.
did i accidetnally delete something that i wasnt supposed to? did installing ROM manager mess something up? i typically dont do anything until i confirm that i am supposed to. i think the problem is that i dont yet know how one thing i do on the phone affects another. i'm guessing when i used rom manager to update the CWmod it changed some folders/files? i dunno!
otherwise, the phone works fine and there are no glitches or hiccups or crashes. So if someone can please take a moment to just explain to me what i did wrong or what i failed to do i'd really, really appreciate it.

you don't have a recovery partition. Either flash one over manually using fastboot, or boot up and try to use ROM Manager to flash CWR.

when you say flash one over using fastboot, do you mean put my phone using VOLUME UP + POWER, connect usb cable, then use command line to do this:
fastboot flash recovery recovery-clockwork-crespo.img
?

Yes, 'cept it will be "fastboot flash recoveryrecovery-clockwork-3.0.0.0-crespo.img" without the quotes now.
But does it say that you're missing a boot.img or recovery.img?
Also, the "not set up for OTA" thing isn't for official OTAs. Some developers have made their custom ROMs capable of being updated that way.

thank you luxferro and unremarked. i did it and it works perfectly. i am now able to access clockworkmod recovery 3.0.0.0. next step is backup my existing ROM and also to figure out how to put the OTA 2.3.1 on and restore all my data
oh and unremarked: it basically said no boot or img file and thats it after i would click on recovery or reboot to recovery trhough rom manager. it was just in red at the top. but now it takes me to the ClockworkMod Recovery

[Q] From 2.2.1 to 2.1

hello everyone
i'm not pro in things like this so don't use the hard terms or something. A few days back, i updated my phone to cyanogen 2.2.1. A friend helped me. I want to downgrade now. But, he hasn't made a backup and he hasn't one. So we tried a few options to downgrade, but all of them doesn't work. So my question is: Has someone a backup? We tried already a backup, but the 'data was to large'. So if you upload, please, be sure that it works!!
Thanks in advance

There is no way to put your LG to original state. From now you can only install moddified ROMs, but you cannot put original ROMs ( from LG)
First you need to enter in fastboot mode and make command "fastboot -w"
That will wipe all data that current ROM create. Now when LG is without that data put it in Download mode, and with KDZ updatr update to any fastboot ROM you can find on this or similar page. It should work without any problems.
P.S If you dont wont to setup phone any time you change ROM, make one backup with Clockworkrecovery or vit Amon Ra.
So if you do something bad, you just eneter to recovery mode, and put all data back .

when installed a fastboot rom you could flash an original rom?

pashinator- I read your instruction you give "long time ago": but nothing.
I can always install any room, but only roms with fastboot works.
Any other roms stuck on LG logo.

I dont understand it even more. Could i downgrade to a 2.1 version with all the old function? And what's a modified ROM? And what happens if i follow your commands a what should i do next? Sorry, but like i said: I'm not a pro in things like this.

Yes you can downgrade from 2.2.1 to 2.1
Process have two steps
in first step you enter fastboot and enter command
fastboot -w
now when your data are wiped pull battery , put it back, press down vol + power to enter into download mode, and flash with any fastboot 2.1 rom.
I didn't success to flash original rom, so I assume you will not succeed also
When I flash original rom, LG 540 stuck in first android animation.
But with fastboot roms, LG540 work perfect.

And where did i get a fastboot 2.1ROM?

since you say this in first post "A few days back, i updated my phone to cyanogen 2.2.1" you already have fastboot rom

But where? The only fastboot ROM i have that i know is the one i have on my phone. And that's 2.2.1
Or am i wrong?
EDIT: or did you mean to update it in fastboot?

And is it possible to use both ROM's the same? So that i can choose which ROM i want to use without up- and downgrade again and again?

Look you must have had a kdz file that you used to flash 2.2.1

fastboot rom is modified rom
but thing that all of us use is clockwork recovery ( home + power)
From recovery you can make restore and backup.
You enter in fast boot
fastboot -w ( to erase data files and cache)
then install new 2.1 rom via fastboot options
reboot LG 540 and voila , you have downgraded your phone.
When you all setup in new rom, go to home + power, make backup of system and then you can change systems by using recovery in clockwork recovery.
So you can have many backups, bat cannot have two active roms in same time, only one.

So after type fastboot -w i can instal the Original v20__A 2.1 LG ROM. And can i make a backup from 2.1 and 2.2.1? And use them both without change ROM?
PS: I haven't seen any clockwork after i let him update. Is that right?

YOU CANNOT MAKE BACKUP OF ORIGINAL ROM.
You can only make backup of modified roms.
But since I , and many other cannot flash original rom after flashing any modified rom I gues that you cannot also.
When you wont to flash original rom then you not need to use fastboot -w , since KDZ updater or original LG service tool will do it for you.
Clockwork is rom like any other. You must flash also recovery image, and then when you power up LG 540 with combination HOME + POWER and then you will see it.

Market
Okay. Sounds maybe crazy but after update, i LOVE 2.2.1 . except one thing. my market is 'unfortunately stopped'. So does anyone know a thing or something to fix it, or an other market? thanks in advance

[Q] Bricked my Desire Z

It seems I bricked my Desire Z. That'll teach me for messing with custom roms
I only get the bootloader (the white screen with coloured text). Everything I do from there either does nothing or just goes to a white screen with a green HTC logo and then hangs.
I tried flashing Cyanogenmod by renaming the zip pc10img.zip, this failed. I tried installing an official G2 rom from the SD, this also failed. When I turn the thing on I get a green HTC logo, when I try to go to recovery it's the same story.
Can anyone help me get my phone back to life?

When you get in to recovery are you getting any error messages?
Have you tried restoring a nandroid backup or trying a different sd card?
And re-naming a rom to PC10IMG.zip will never work

I don't get an error message, it just hangs at the HTC logo. Same when I reboot the phone.
I don't have a backup since the last time I tried using one, it didn't work. Besides, I don't have Clockwork so I wouldn't be able to restore it even if I had one

You cant get in to clockwork. have you tried using adb?

Not yet. Is it possible to flash a rom or even just clockwork through adb?
I'm sorry for being such a n00b about this, I'm just not that experienced yet with android devices. Used to change roms on my WinMo device all the time but Android's... quite different

If you have the ENG Hboot you can flash the recovery from fastboot....
If you have the sdk set up on your computer do the command (after putting the clockwork recovery in your sdk folder):
fastboot flash recovery recovery.img
then go to the recovery, wipe and flash

I now have the issue that ADB won't see the phone. The phone says HBOOT USB PLUG so it knows it's connected through USB, it shows up in my device manager but ADB won't recognise it. Any suggestions?

adb won't work in hboot/fastboot mode, you need to get the fastboot executable.
It might be in your tools folder for adb.
You can make sure its working by running 'fastboot devices'

Thanks! Fastboot detects the device Now I can try to fix stuff.

It worked! I managed to install Clockwork Recovery using Fastboot and after that installing Cyanogenmod was a piece of cake Thanks you guys!

The most important thing I learned from playing with roms is how to read the manual. Be careful out there.

Ahem, guys, where can I find fastboot executable? I checked everywhere in the android-sdk directory but I can't find it. I even updated to the latest SDK tools, and yet fastboot is still MIA.

Always and I mean ALWAYS create backups of your working roms, I cannot stress this enough.
You can copy files onto your sdcard using adb then force boot into cwm. Thank goodness for adb

I bricked my Nexus S. Please help.

I tried looking around the forums to see if someone has had this problem before. Couldn't find something similar.
I had stock 4.0.3 installed and I saw today that 4.0.4 was being pushed out. Since 4.0.3 wasn't a stock build I tried to downgrade to 2.3.6 in order to keep everything stock. I rooted the phone, installed the ROM Manager and flashed 2.3.6 through Clockworkmod Recovery. Everything went smoothly but when I powered on the phone force quit messages kept popping up and I can't get past the welcome screen. When I go into Fastboot mode and try to go in Recovery mode it just shows the Android symbol and a warning sign. I tried flashing a recovery .zip file I found online through fastboot but couldn't manage to do it (I'm on Mac OSX)
Can someone please help me? I'm completely desperate and wouldn't care about erasing everything (I think I already did, actually).
Thanks in advance.

flash a recovery.img
that multiple fc happened to me when i installed a i9023 rom on my i9020a.
unzip the recovery.zip and flash the .img file through fastboot and make sure you have the right rom for your model

Thank man, but that's what I tried to do. I got confused and wrote that it was a .zip up there. I'm really confused and couldn't flash the .img. Could you walk me through it? or point me to a thread that shows me how to do it?

im not sure how a mac is set up, i can walk you through flashing it on windows through command prompt ...

Please do that. I guess I can try to work it out.
Thanks

memorize that lol it saved me.
you can skip the root part, but it explains how to set up the pc so it'll read the nexus with the correct drivers and whatnot, and what commands to run to flash the recovery. then when youre in the recovery, mount as usb, copy over 2.3.6 (the right one!) and install from zip.

I just tried that. I get this message: "error: cannot load 'twrp-crespo-2.0.0RC0.img'" I don't know what to do!

Can you get into boot loader mode?
Have you tried to use Odin?

[Q] hours for searching for nothing help plz!

I ****ed up my phone today I did full wipe (formatted internal storage too, so i can't flash any rom in recovery because there is nothing) and now i've been searching hours someone who can help me? In TWRP i can't mount anything to my pc (i do not know why?) AND adb says me "devices not found" or something like that so can't push any zip-file to my phone via adb sideload. Is there any way to reapir my phone? can someone help me? Thanks alot!

There was a bug in a bunch of recent twrp releases that causes adb to not work in recovery. Patched versions have been made, try finding one for your device.
Added:
If you can't find a patched version, flash cwm or philz recovery with fastboot, adb is working on both of those. You just need a rrcovery image and do
"fastboot flash recovery <recovery-file>.img"
In fastboot mode.

let's try it out!

See the edit to my first response. Fastboot is done in fastboot mode, not recovery, so you should be good. You just need the basic .img file of cwm or philz recovery.

If you are on win 7 try this:
http://adbdriver.com/downloads/
(Adb driver installer)
Run it when you turn adb sideload on in G2 and connect it to PC.
If it fails you still can go buy somewhere USB OTG cable (few bucks) and flash ROM from usb stick like me.

It appears that accessing fastboot pn the lg g2 is not so simple. Sorta like samsung phone deal, where a manufacturer download is used instead. From what I gather, recovery might need to be wiped to access fastboot, which you could do from terminal in twrp, but thats risky. Apparently, a lot of people have gotten stuck in fastboot mode. Best bet would be to reflash stock firmware through lg download mode. Also see this thread for a method to return to stock firmware:
http://forum.xda-developers.com/showthread.php?t=2432476
Once you are back to stock, just reroot and flash revovery, etc.

downloadmode should still work. go back to any kdz for your version
also source and versions post next time
