Fastboot Help!!! - LG Optimus G (International)

I tried to flash a new ROM (which I've done a million times) and now when I press the power I get the text in the lower left corner that says FASTBOOT MODE and then all the text following and I want to know how to boot into recovery to restore my backup. I'm using TWRP on the LS970.

Reboot into recovery and try clearing cache. Or do a full reset. If not load another ROM on. Did you perform a nandroid back up first?

You need to flash the boot.img included in the rom zip file, separately in fastboot.
Coz it wants to emphasize n make sure that u agree that its Quietly Brilliant ..
Just say out loud " ya I agree n its brilliant indeed..All hail HTC One X" ..n then its gonna move on for sure..
On a serious note..Did u flash the kernel correctly..I mean did u clear the cache in cmd?

To flash the boot.img, the command is "fastboot flash boot xxx.img"
With xxx.img the name of the boot file you want to flash.
You need to go in fastboot on the phone press and hold power + volume down.
On your PC, use fastboot on a cmd windows.
Hope this can help.
Please follow instructions on howto install custom roms they are included in first post of mostly every custom rom.
From what you say you probably didnt flash boot.img at all. So you are in a bootloop. Flash boot.img of the custom rom and restart your phone and it will boot correctly
Hi,
thanks for your help, i did not a perform a nandroid back up first.
I cannot enter in recovery mode, so i went to fastboot and installed Clockworkmod Touch Recovery 5.8.4.0. But i cannot enter again on recovery mode.
I started in fastboot and did the command fastboot flash recovery (the team win projects recovery image):
when pressed enter first time - failed battery low, second time - failed remote 00000008, third time is sending the recovery, does it take some time?

It takes the most a couple of seconds. Please read some how-to's before flashing !
Charge your batt to full !!!
1 : is to unlock bootloader
2 : to flash a custom recovery
3 : backup existing (original) rom
4 : wipe everything
5 : flash the boot.IMG with fastboot commands
6 : flash rom in recovery
And before flashing the boot.IMG erase cache and also after flashing the boot.IMG with fastboot command.
Also erase cache after flashing the custom recovery !
Please correct me if i'm wrong

Iam inside of clockworkMod recovery, what i have to do to clean everythink and start again?
You should have flashed the boot.img before flashing the ROM.
Steps to get out of boot loop
Hi,
You are probably in a boot loop because the boot.img you have is not compatible with the custom ROM or is not correctly flashed. First charge the phone upto at least 50% battery (to be safe). Then try following the steps below:
1. Download this pack>> Fastboot Pack http://forum.xda-developers.com/showthread.php?t=1616741
2. Extract the boot.img from the Custom Rom you are trying to install in a folder on your computer.
3. Extract Fastboot Pack into a folder on your computer and replace the boot.img by the boot.img extracted from the Custom Rom in Step.2
4. Turn your phone OFF
5. Turn your phone ON in bootloader mode by holding the power and vol down buttons at the same time, your phone will start in HBOOT mode. It will be displayed somewhere in the middle of the text.
6. Use the volume keys to move up and down the list, and select Fastboot, then press the power key. Now your phone will come in FASTBOOT mode.
7. Connect your phone to the computer via USB cable. Your phone will now display USB FASTOOT instead of just FASTBOOT.
8. Run 05-erase-cache.bat
9. Run 06-flash-custom-boot.bat
10. Run 08-install-clockwork-recovery.bat
11. Disconnect the USB cable. Your phone will now again say FASTBOOT.
12. Use the up or down volume key to select HBOOT and press the power button. This will take you back to HBOOT mode.
13. Use the volume keys to scroll to RECOVERY and press the power button.
14. This will take you to Recovery mode, now you can flash the Custom Rom you want using Recovery mode.
Let me know if I helped by clicking Thanks

[Q] HTC One V Recovery doesn't work, Phone Stuck

Hi Y'all, sometime lurker, first time poster.
I got an HTC One V (CDMA, Virgin Mobile) today and given the relative ease of rooting my old Droid Inc I thought it would be a breeze to do this phone as well, but I did not do enough research and messed it up. Here is what I did as best as I can recall:
I unlocked the bootloader without a problem using Fastboot.
Then I flashed CWM recovery through hasoon2000's all in one tool, but it didn't work. I believe I did not flash the correct CWM (CDMA). I tried reflashing stock recovery, and then CDMA CWM recovery, but I couldn't get past the white HTC with the red warning message.
Because I couldn't get recovery to work, I thought maybe I should flash the kernel. I was using hasoon2000's all in one tool, but I did not realize that it would try to boot into recovery in the middle of flashing the kernel (yeah, I'm a noob and an idiot).
So now it won't load into the standard ROM anymore, it just gets stuck on the HTC White screen with the Red Warning. I can get it to load the bootloader, and I tried flashing the kernel from the all in one tool through fastboot, but it didn't work.
Is there any way I can save my phone or am I out of luck?
Thanks for any help you can provide.
Get the stock boot.img and put it in your fast boot folder and go to cmd prompt and type
C:\fastboot
Fast boot flash boot boot.IMG
Make sure your in fastboot

Thanks XxlemonxX. I did that a few times and it didn't seem to stick.
But! While I was fastloading I went ahead and did the Superboot step found here:
http://forum.xda-developers.com/showthread.php?t=1598964
And the phone restarted! Huzzah! Now I just have to see if I can get a recovery actually working...
OK, so things got a little strange.
The phone booted up just fine, so I tried flashing CWM recovery again. It worked, and restarted into CWM recovery. The power button didn't seem to work for selecting various options for a while, it would just go to the screen with the cog and the top hat, until I held it down for a few seconds, after which the bottom buttons flashed, and at the bottom it said "back button enabled". Then the power button worked for selecting various options. (I'm not sure if this is how CWM recovery is supposed to work for the One V, as I can't find any definitive answers...). Anyways, ran a backup through recovery, but afterwards the phone wouldn't reboot again.
Since it worked before I ran the Superboot app through windows and bam, starts up again. Did a factory reset just to see if that would clear the rebooting problem, but it didn't. It did change, however. Now it goes to the white HTC screen with the red warning for a second, goes back to black, then goes to a really dark black with just the red warning barely visible for about 7~ seconds, then it powers down. The only way I can get a reboot into the ROM is to redo the Superboot app...
I'm a little nervous at this point. I tried flashing an MIUI rom through the CWM app but there was an error (I didn't write it down, sorry), and I can't find a reliable link to the stock RUU VM PrimoC Rom (jmz's links are down as far as I can tell). I just want a rom that will reboot without freezing, haha. Thanks again for any help.
tl;dr Phone only boots when Superboot app is flashed, try a different rom?

That is an old cwm. thats how it operates. Once your booted into the system you can install rom manager from play store and then you can update cwm so you wont have to enable the power button for use. But anyway seems you cant boot into a stable system right now. So If you are willing to follow theses instructions you can get back to factory conditions.
1. get the fastboot package if you dont have it. http://www.mediafire.com/?4dx982z93w8z7wk and put those files in a folder in the C drive.
2. Get the ruu from here its the top one if you are virgin mobile US. http://www.filefactory.com/f/0eafb9c43276c308/ look for RUU_PRIMO_C_ICS_40A_Sprint_WWE_VM_1.08.652.6_Radio_1.00.00.0521_2_NV_VM_3.46_0503_PRL61008_release_262414_signed.exe
3. This is how your going to get the stock recovery and stock kernel. run the ruu but dont do anything with it just yet. After the ruu is opened and is at the welcome screen just click and drag the window down out of the way and open ANY folder and type %temp% in the address bar of that folder and press enter. You will see a bunch of folders with titles like this "{B2B09672-51AB-4EF6-BDDF-50CB9719052B}" This is just an example. While in that temp folder just do a search for rom.zip and when you find it you can copy that file to your desktop and then just click cancel in the ruu welcome screen for now.
4. Open the rom.zip file with 7zip. You must use 7zip. The built in windows zip program wont work. Once its opened with 7zip, extract these two files 'recovery_signed.img' and 'boot_signed.img'. This is your stock recovery and stock kernel. Extract those to the fastboot folder.
5. You must somehow get your device into the bootloader again. I had the same symptoms as you did with the dark screen and dim red text. I just kept playing with the volume down during boot and eventualy got there. DO NOT USE VOLUME UP!!
6. Once your in the bootloader choose fastboot and plug your device in and it should now say fastboot usb at the top of the bootloader screen. Now run theses commands.
7. Commands to run.
fastboot flash recovery recovery_signed.img
fastboot reboot-bootloader
fastboot erase cache
fastboot flash boot boot_signed.img
fastboot reboot-bootloader
fastboot erase cache
fastboot oem lock
fastboot reboot-bootloader
fastboot erase cache
8. Now while in bootloader fastboot usb still just run the ruu and follow all instructions. Make sure you have atleast 30% battery while performing this. And if all goes well you will be back to square one.

[Q] Maybe in a bootloop?

Rooted my phone using Temporary CWM method, installed Titanium Backup and restored from my old phone. Selected All Apps and Data. Rebooted my phone and I assume that it is now stuck in a bootloop. It gets to the ASUS and Intel Inside screens, then I get a spinning circle forever (well, at least 3 minutes).
Where do I go from here? Reflash the ROM and start over and don't restore system data? Is there an easier/quicker way?
Thanks
Go to fastboot mode by holding the power and volume up button,connect USB cable be sure that you installedmusb and fastboot driver.go to folder of fastboot and hold shift key then right click open command window here and type:fastboot erase cache then enter fastboot reboot and voila..
Thanks for the reply, but that didn't do it.
I was able to execute the commands, but still no luck. I got into recovery to try and wipe from there, but got the dead android. I them held power up and tapped vol up to get into recovery. tried to wipe cache from there and the phone just sat there for 3-4 minutes with nothing. Now when I get into recovery, I get a flashing dead android, and the power/vol up trick doesn't work. I can still boot into fastboot.
Di I just need to reflash the stock image? Or is there something else I can do?

I had the same problem as yours and it took 3 hours before i figured it out and managed to run the phone normally.I downloaded all the files,drivers and latest prerooted system img. here in this forum.you can download it there and there is the instruction how to do it.
To Begin :
1. on Fastbootmode connect your device and on the flashtool folder hold shift key and right click and go to open command here,be sure that downloaded images are in the same folder.Recovery img.,Boot Img. and the big pre-rooted System img.
2. type fastboot devices then hit enter key - the device nos. should appear and you can start now to flash...
a. fastboot -w then hit enter this will erase the system
b.fastboot flash system system.img then hit enter key
c.fastboot erase userdata then hit enter key
d. fastboot erase cache then hit enter key
e. fastboot reboot then hit enter key..
THANK YOU!!!
Thank You, Thank You, 1000 times, Thank You.
I did everything you mentioned, with a few small exceptions
1. Make sure you have the lastest version of Fastboot
2. Instead of step b above, I did the following. Not sure if it was needed or not, but it worked for me
fastboot flash fastboot droidboot.img
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
3. At the end, after I did a Fastboot Reboot, I got the dreaded dead android again. I nearly cried. However, I rebooted again, and everything seemed to work. Note that on the first boot, it may take 2-3 minutes for the OS to come up.
4. All of the files and great insight can be found here: http://forum.xda-developers.com/zenfone2/general/asus-zenfone-2-flashing-recovery-mode-t3096596

Trying to install TWRP but the phone keeps overwriting it

Trying to install TWRP v3. Phone is unlocked (not rooted yet as not necessary atm). I'm able to sucesfully push the .img to the sdcard via adb and install via "fastboot flash recover twrp.img" but the moment I reboot the phone and try to access recovery to get into TWRP, all I get is a little icon of an android mascot lying down with his belly open. No TWRP.
I know the phone will auto-overwrite custom recovery's if the correct combination of hardware buttons are not pressed after the first TWRP install (as TWRP needs to patch the default recovery the first time to stop the phone from constantly trying to overwrite TWRP every time) but so far i've not been able to find out what it is (i.e. not the usual vol +- and power all at the same time. Its gotta be something else?).
Edit: Delete his post. I figured it out. Turns out it isn't a good idea to execute "fastboot reboot" immediately after TWRP installation
Don't restart the Phone!
Flash Recovery and the do the following:
Use the volume keys to scroll and power key to select the Reboot Bootloader option. Once the phone has booted back into the bootloader you can use the volume keys to scroll and the power key to boot into your newly flashed recovery. It's now safe to disconnect your usb cable.

Tried flashing CM13, now can't enter normal boot

So I already had a rooted (and I'm pretty sure unlocked bootlader) version of the stock Asus and wanted to put CM13 nightly on there. Everything was going smooth until I got to the stage where I have to load into TWRP and I got the error screen with the little dead alien and the red symbol.
Now I can't enter normal boot, but entering recovery mode seems to work. I tried the option to side load a package from ADB on that screen but nothing worked (.zip files extracted, but I got an error on the phone).
As you can tell, I'm really new to this so any help would be greatly appreciated. I tried looking around, but it seems the more common issue is people not being able to enter recovery mode or something similar.
Thanks
Looks like your doing it wrong. Being rooted does not necessarily mean that your bootloader is unlocked.
By the looks of it your in recovery mode with the dead robot with the "error" message. That is normal. To reboot back into system you either have to press (I don't remember) power button and volume up or down button. Then you should see some options with reboot to system. Or if that does not work you can hold the power button till it turns off.
Then you get back into Android, download the official bootloader unlock tool from ASUS and install it on your device. NOTE: If you updated to MM then this will not work and this will void your warranty.
Run the tool and press unlock and it should reboot into fastboot where it should begin the unlocking process. I believe it should automatically reboot and you should see that the Asus logo is now black instead of white. If not, repeat the process.
You can now proceed to flash twrp recovery. Boot into fastboot/bootloader mode either with "adb reboot bootloader" or hold a specific set of buttons while off to go directly into fastboot.
On the computer, connect your device and type in "fastboot flash recovery (path to twrp IMG without brackets)"
When done you should be able to reboot into twrp recovery where you can flash the cm13 zip.
Hope this helped.
