[Q] fastboot mode - G2 Q&A, Help & Troubleshooting

I have read some articles on here about this but my problem is slightly different. My ROM works fine but when I select to put my phone into recovery mode the fastboot mode text comes up I power my device off and it starts back up in cm 10.2. Since these seems to be a little different than others problems I've read on here I've been hesitant to try any of the solutions. And if it requires me to use a computer I only have access to a mac

So, install Windows on it... or run a live version. Or VM one.

That doesn't answer the problem on my phone.

Are you trying to reboot through the Rom our another app like titanium? Some if the root apps cab tell you if you have a recovery. Maybe the recovery is messed up so it forces to fastboot. Just my thoughts, no expert.

I am using ROM manager. thats what the problem is im pretty sure is the recovery is messed up. I don't know how to fix it.

Get flashify. Flash twrp or cwm recovery per your variant. They are posted around here on forums. Never flash anything again with ROM manager. It is what blew your recovery. You're lucky your ROM even works.

Didn't know that about Rom manager. Is it just because of our g2 or compatibility with the recovery?

I'm not sure, I just know it cant flash them right. Never looked into it. Could be due to boot loader problems, partitions, ect. Probably something simple.

Please be more specific.
What tutorial did you use?
Did you download clockwork recovery?
Do you have the superuser zip?
If you can enable fast boot and fastboot flash recovery you should be able to mount your usb storage in CWM and then install a ROM and the su zip.

i used the one mentioned in addictive tips website (http://www.addictivetips.com/mobile/how-to-root-nexus-s-with-a-single-click-using-superboot/). i basically followed what these guys had mentioned.
since this failed i read that the other option is to go through fastboot > recovery > and clear everything but this did not change anything.
can someone give me a step by step guideline on how to continue. i dont mind going back to the stock 2.3.4 android. i just bought the phone yesterday
Which version do you have? The sprint or t mobile? Check if you can go into fast boot hold down volume up and then powerbutton. If not you may have to Odin it if not. That super one click looks old..

If your ROM flashed incorrectly, it would lead to your phone being in a state where it just shows a GOOGLE with a Padlock; kind of like turning on a computer without an operating system.
You would have to read the instructions on rooting your phone, which involves using fastboot and flash recovery from fastboot (All this is in the rooting guide). Simply reflash the recovery so you boot up back in recovery and try flash the rom again.
The same happened to me, I fixed it buy flashing a stock boot.img

thanks for the replies. how do i flash from the fastboot mode? when i plug it in to my computer i cant see the drive but my computer can detect the nexus s is plugged in
Set up adb first, they have the guides in the dev section, I used wolverines guide, you'll have to look for the software img, I don't know where it is at for the GSM model. Good luck

Sounds like you're rooted and have recovery installed, but your OS is hosed.
Flash a ROM.
thanks for the replies guys. i have the adb setup on my laptop. i took it to one of the stores and he said he cant reflash it for some reason. he said he needs to get some software off samsung and it will take him a day. my phone is brand new and i didnt wanna trust him. do u guys think i should use odin? one of my friend has a galaxy s and he said odin should work fine on my phone.
Can you get into the ClockworkMod recovery menu? Turn the phone completely off then hold VolUp and Power until you get into Recovery.
If you get there, you're golden. Just download a ROM (I recommend Deck's) and away you go.
i can get into recovery but it gives me option like wipe everything and i selected that. but when i reboot the phone the same locked screen pops up. anyone from toronto here who i can contact?

Basically with those wipe commands you make the Rom unuseable. You have to flash a new one or apply it via Odin. There are various guides on this forum section. Odin requires less technical knowledge but is a bit more risky then flashing via recovery. Odin and the Roms for that method can be obtained from samfirmware.com. Zipped roms can be found in the development section here.

Help me please

So I've been messing around with android phones for a while now and I'm stuck. I was on the oxygen 2.1.6 Rom then decided to make a back up. However instead of going into CWR it just went into fast boot. When I go into recovery it just says fast boot mode no reboot or recovery img. I tried to odin back to stock like I usually do but adb wont recognize my device like it usually does. Please don't tell me I'm bricked and that I messed up bad. Any help would be appreciated. Thanks in advance.
I tried reinstalling drivers etc etc. Somebody help me lol

It sounds like you flashed a bad recovery. Download a new recovery , boot into fastboot, and

Adb only works when the phone is booted normally, provided usb debugging is on.
Use fastboot. If you want to make sure it's working, boot into fastboot mode and
Code:
fastboot devices
If it's working, you will see your serial number.
If the other options can't help you get your problem solved try Odin.
www.samfirmware.com
get the right files for your device and Odin program itself. There are tutorials on here how to use it.
sorry I was being an idiot. I tried fastboot and it showed nothing connected. When I flashed a recovery it just hung waiting for device. I have all the drivers loaded on the computer but my device is still unknown and wont be recognized. I have all the odin files and I have used odin before. This sucks
btw appreciate the help guys

Try installing pdanet, that will install all the drivers you need for fastboot and Odin.

my one click works on both versions, as all it does it just gets you root. if you want cwm then use rom manager afterwards.
but for his problem no it relies on adb and fastboot

Maybe not, but it does include some handy files. ;-)
Download and unzip Shabby's OneClickRoot
Install pdanet. (See the readme for which one.)
Reboot your computer.
Then try using his version of fastboot.
I'm assuming you are in fastboot mode (it will say so) and that you're using the usb cable that came with the phone.
I will give it a go now I do have PDA installed too

I think I broke it

Not sure exactly what happened. I was using the tablet and all of a sudden the bottom three buttons disappeared as well as the top bar. The system kept getting force closes. I rebooted and it just sat in the reboot mode. I tried to recover from the system but that is not working. I cant seem to get the system to mount via usb now. I am in clockwork mod v5.8.0.2 and do not see an option. If I could mount it I could put an img file back on and get it to work. Any help would be great.

You could try to flash back the stock software to see if that helps? Look here for some help.
Are you running a custom ROM or anything else? ALSO, once you do manage to get everything fixed, I would upgrade your CWM to the most current version 6.0.1.0 by flashing this in the older (5.8.0.2) version.
Sounds like it might be permission related, you could try a 'fix permissions' in recovery

Did you download the nakasi file from the google site? You shouldn't have an issue with that. And you can update CWM using ADB, just check over in the Android Development section.

ok. i was on stock. rooted with the IO method. wanted to flash a ROM (clean rom). downloaded ROM, wipe dalvik/cache/data. after reboot, phone booted into recovery mode. tried going into download mode to revert back to stock and LG FlashTool failed. said phone was the wrong model number (D802). the ROM i Downloaded said it was for VZW G2. obviously it wasnt. so i finally ended up using fastboot to push boot image and it booted, but in about phone, it says it D802 model (i just got it to boot, where as before i was stuck in fastboot mode). now i need to return to stock, but dont know how. any ideas?

I was thinking the same thing. It's best to stay out of those modes. Get a recovery installed ASAP and do everything that you need to do from there. I recommend TWRP Recovery.
Sent from my LG-D802 using XDA Premium 4 mobile app
Maybe because when flashing stock rom download mode is needed (atleast in my old sammy phone, maybe same in moto phones)
What's wrong with restoring the backup of the stock rom that should have been made before wiping and flashing a different rom? Not sure what I'm missing here.
Sent from my Nexus 10 using XDA Premium HD app
Download mode is useful to flash the entire phone back to stock using the OEM tools. It's not just for the stock ROM. It's everything. It's useful if you get a bit carried away in TWRP and wipe partitions you really shouldn't be touching. Or if you somehow manage to bork your recovery, or at least can't get into it. It's also good if you want your phone to be completely stock to sell it or to send it in on warranty. I'm sure someone could come up with other scenarios where it's useful.
But yes, it is a good idea to keep a backup of your stock ROM. And as always, know what you're flashing, make sure it's for your phone and check md5s. And be mindful of what you're doing in recovery. You should be able to avoid most issues. Download mode is indeed something you shouldn't be using often but as I said above there are situations where it is useful or necessary. It's actually something I suggest you know how to use. I say it's always a good idea to know how to get back to complete stock for warranty stuff, selling, or if something just goes majorly wrong.
The Rom I was trying to flash was apparently for a different model number, yet it was under the Verizon thread. There was no md5 to cross reference. In the end I ended up finding the proper boot image/twrp files and pushed them via fastboot (since I was unable to use adb) which then allowed more to restore a backup of the original Rom. Just took me all night to finally get back to stock. Then I decided to restore to out-of-the-box stock just to make sure all files weren't corrupted our anything.

You can you adb side load which is the same for flashing rom, pushing, or pulling file from the phone which is the first thing to learn before flashing anything to the new device that you got and know nothing about.

Here's one thread. You should Google it for other I instructions but there are tons of them. Also try to find the adb and/or SDK download files.
Sent from my LG-G2 using Tapatalk
OK, still working on this. Dont have but a few hours here and there to get this running again. Been to tons of pages reading, reading and more reading. Downloaded and installed SDK manager. I guess it also installs ADB. I found it within the SKD Platform-tools folder but when I click on it all it does is open, goes thru a ton of commands then closes. I also found it in C:ADB folder. Does the same thing. Doesnt stay open so I can type anything in it? Ive got flashtool installed also. I cant get into download mode on my phone either.
Also trying to go this route LG G2 Stock Firmware (Go Back to Stock) in General section but dont know exactly which file to download. Right now downloading the VS98010B_13 file. Probably need the VS98011A_01 but man it takes an hour to download. Which one do I use? Also dont know if I have the D800 or D802? My box says LG-VS980. Dont know if that matters. But again I dont think I can use this method as I cant get into download mode.
I do download the KDZ files and not the TOT files right?
Any other help would be greatly appreciated. thanks
Try the return to stock method with the vs98010b file first. Sounds like ur phone took an OTA hence the recovery bootloop. If u can get back to stock I'd root right away and stop any of the OTAs. U can just flash the 12B ROM and radios after installing a recovery.
Don't flash or use any files for d800 or d802, Verizon model is vs980.

If your in twrp have you tried to aideload a ROM then see if it flashes? Just need adb installed on PC and setup, drivers installed and ROM on hand.....
