Problem with fastboot - LG Optimus G (International)

Hi
I currently unlocked my bootloader with installed cwm.Then i tryed cm10,1 but got back to stock again because of bad battery life with cm. I flashed my kdz and everythin works as usual. I even rooted it again but now i cant enter fastboot mode. Only hard reset menu and stock recovery but not fastboot. What the heck happened? I cant run freegee again because i already did it?

EDIT:
Fastboot works again. As i can see is that flashing KDZ locking phone again and you need to root and run FreeGee again in order to get into fastboot to choose recovery again.
It works now. I run FreeGee and now it enters fastboot menu and recovery.

Please Halp! Recovery Issues!??

Ok I have rooted my phone a Z00A with 16gb/2gb using this Video youtube.com/watch?v=9l-l96jtt10 and installed TWRP but whenever I try to install and boot into recovery it boots into fastboot instead same as when I try to install a rom. How do I get into TWRP and get rid of Fastboot?
The main problem is fastboot, it's the only thing my phone will load and all the options except for power off just reset the phone into fastboot. If i hook up to my pc and use Fastboot Recovery Launcher I can get it to boot into TWRP with all it's functionality but no matter what I do once I reboot it's back to fastboot screen. I have tried to install SuperZenR19 and the CM12 roms and even formatted data before installing a rom but still it reboots to fastboot.
Enable USB debugging and connect it to system.
Open up the fastboot (command prompt) and flash the recovery again.
Use SSJ Tethered Version (Permanent) version and then try.
Make sure you flash it by using fastboot
'fastboot flash recovery filename.img'
Remove ' '
Success!? Nope!
Ok I reran the CWM cai dat and finally booted in TWRP, just flashed SuperZen 19. Thanks for the replies and wish me luck! The stock os is just such memory hogging garbage that I hope I will get better performance now.
*** EDIT***
Spoke too soon, I was able to install SuperZen R19 but it won't boot into the system just goes to fastboot. The only way it seems I can get back into TWRP is to run cai bat hit T4 and TWRP will load but upon reboot it's back to the fastboot screen.
****EDIT**** It won't boot into anything but fastboot after a reboot, it's not bricked but pretty damn close. I can get it to load twrp only if I go through Cai bat but even so after I install and wipe it just boots into fastboot again. FIDDLESTICKS!!
You are following the old TWRP method Dude.
Follow the latest one and then flash a stock rom and check if the problem persists.
Unlock the bootloader too. To flash roms and permanent TWRP.
Tell us if any luck.
Factory reset from the menu also clear cache?

I got it working finally after I was able to flash boot and droid boot and then installed Barebones and it finally booted. I'm probably going to leave it alone for now.

Unable to flash custom recovery

Hi,
I have the Find 7 with the new display panel.
I wanted to flash the latest version of TWRP but failed. I do not know what I did wrong.
I can use adb and fastboot without any problem. When trying to flash recovery, it says there that the flash was successful but when I reboot to recovery, TWRP was not installed and the original Oppo recovery is still there.
The bootloader is unlocked. And I tried relocking and unlocking again but to no avail. Whenever I use the command "fastboot oem unlock", nothing happens to the phone.
I am currently on spectrum. I want to try other roms such as the lite COS 2.15 and also maxwen roms since that only those supports the new panel.
I am also trying to get root for my phone and it is impossible without custom recovery.
Thanks for any help.
I had poop loads of issues with getting custom recovery on my Find 7a. Eventually I used these instructions:
http://community.oppo.com/my/forum.php?mod=viewthread&tid=996
They work. Don't know if it's the versions of ADB or Fastboot or something.
Give it a go

I will give it a go when I get back. Thanks!
This is what a forumer from the official forum said and it works:
After you had successfully flash recovery via fastboot, you MUST NOT reboot the device. AFAIK, if you reboot the device it will restore the recovery back to stock oppo recovery.
So instead, you need to immediately press vol down & power button on the fastboot screen. Keep holding the button until you see the TWRP recovery screen. Hope that helps. Cheers!""

Unlocking bootloader erases data?
Mine wouldn't flash recovery. It said successful but I still had oppo recovery 1.2 and it only worked when I found the latest official twrp over version 3. after flashing, I disconnected usb and then held down power button to shut the phone down. It then was able to boot to twrp ok.
I used the latest one.

Only fastboot works on my zenfone.

Hi. I'm terribly lost.
I bought a ze500kl (z00ed) and played around with root, twrp and marshmallow. The last thing I did was installing marshmallow and then I wanted to flash twrp.
What I ended up with is a phone which you can't boot, you can't get into recovery and I'm not even able to flash any other recovery than the stock one. And even if I flash it 'successsuccessfully' I'm still not able to boot into it.
Code:
fastboot reboot-bootloader
yields the phone starting back into fastboot mode.
As far as I understood my bootloader seems to be locked.
How can I get my phone working again?
The command fastboot reboot-bootloader only boots you into the bootloader, meaning to the fastboot. If you want to boot to recovery, you need to select this option in the fastboot menu. I don't remember if you can use a fastboot command for that, and I can't turn off my phone to check.
On the ze500kl, when phone off, press vol- and power to enter recovery.
some progress
Thanks for the info. I did already try to wrok with the vol- button but it just keeps showing the ASUS and android logos and doesn't start twrp. I've succeeded to install the system thanks to the following site: (I c'an't post it cuz I'm not here long enough) however now I'm again not getting into twrp.

If you haven't unlocked your bootloader then you can't flash TWRP. You need to unlock bootloader. I have the 551ML so can't help here. Try the search function and read...
Try to erase your cache partition in fastboot with the command "fastboot erase cache", this might get you booting back into Android but since you've been playing around without doing the necessary reading, no guarantees...
To get to recovery, stock or custom, you must go through fastboot or bootloader mode. You need to use the volume key until it says recovery then hit power key. It will reboot the phone and most probably show you a droid on its back with "Error" above it (if it's still stock). Hold down power and press volume up to enter recovery.

I did qutite some experimenting today. What I'm currently ended up with is:
1) I can boot into the system.
2) I can't boot into the recovery of the Phone
3) I can boot the StockRecovery via fastboot however I can't boot TWRP by any procedure (Although I was able to do so during my experimenting. I don't understand why it sometimes works and sometimes doesn't)
4) My Phone is Rooted (at least it says so)
5) I have run the Unlock.Zip via TWRP when I had TWRP flashed however now I'm again at a point where I can't start TWRP at all.
I find this very confusing and I can't see any pattern to it. For now I'm OK with having a more or less functional phone but I'd like it to be more reliable and predictable in behaviour.
First of all you can't boot directly to recovery the way you are thinking. Booting into fastboot (actually called the bootloader) then selecting recovery is the normal way. You can't have 2 recoveries on your phone. So you probably did the tethered version of TWRP the first time. I don't have the link handy but you need to get the official TWRP and use fastboot to install.

You HAVEN'T UNLOCKED YOUR BOOTLOADER...
No recovery or custom rom will flash successfully... It will say it will, but you will either go into bootloop or just get stuck at ASUS logo...
Nothing will stick until the bootloader is unlocked, if you use tethered TWRP and flash a custom rom you will softbrick your phone until you flash a stock rom back on.
If you go ahead and flash TWRP onto your phone using fastboot then you will have NO recovery on your phone.
You have been warned...

Well I disagree and I think you are wrong . I strongly assume that I have TWRP installed as I'm able to boot into it without having the phone connected to the computer.
Consequently I HAVE unlocked my bootloader and I DO HAVE a recovery on my phone. And of course I'm not able to install a custom rom seing that there aren't any for my model yet.
I think however that I've (for now) [SOLVED] my problem and we're drifting away from the original topic. Thanks for your quick help :highfive:

Recovery is gone after boot unlock,twrp install attempt.

Recovery is gone after boot unlock,twrp install attempt.
I tried to instal TWRP before unlocking the bootloader, it failed so i tried uaing the official Asus unlock tool and the twrp again it still fails.
Now i cannot access recovery at all, it just reboots into fastboot. I choose recovery but dead android never shows up. Just fastboot again.
How can i flash the original recocery back?
I have tried through adb (failed) and using the microsd card (flash does not start, just reboots to fastboot) method.
Otherwise the phone works as normal.

After it reboots into Fastboot use your volume rocker to navigate it to Recovery. When the screen goes black, press power and Volume up and when you release volume up it will take you to stock recovery.

Along with an unlocked bootloader you Need USB debugging turned on. Then while you're in bootloader use 'fastboot flash recovery (IMG file) ' to flash your recovery

Success!
i didnt have the recovery.img file
downloaded it and flashed through ADB ( after disabling my screen lock or you get "permission denied")
i can now get back into recovery.
thanks very much. been battling with this for a week.

Phone can boot into fastboot, and system but wont go into recovery

Hi guys i flashed the 3.5.3 CM today but i decided to go back with 3.26 again, so i followed a guide that tells me to install stock recovery over twrp before i install the rom but after i fastboot flash the recovery i cannot go into the recovery anymore.
i tried to flashed the modified twrp and then boot to recovery but still wont open it.
the phone works and can go into fastboot still but it just wont access recovery
anyway to fix it? sorry if this has been discussed before. im on a mac for more info
TIA
1+3
Is your OS booting?
yea
Got the same problem here. Can boot into system and fastboot but if boot to recovery i get the oneplus logo and the bootloaderscreen and then i get a black screen where i should get my recovery. And if wanna Force shutdown my oneplus it freezes somehow. I tried everything to fix this with no result. Stock recovery doesnt work too.
Hi I just had the same problem, I have sent it back to Oneplus for repair. According to the ticket, I had a faulty motherboard, which has been replaced. If you can, do it. I only had to wait for a week before it was sent back.
Had the same problem last night. Following method nr 2 in thos thread solved it.

using fastboot to wipe the recovery partition then fastboot flashing modified twrp twice worked for me, i think the oneplus recovery image thats doing the rounds doesn't want to play nice lol
If youre phone boots in to system, download Flashify from play, flash recovery.img (you need to extract .img file). Go to recovery to check if it works. If not try other recovery.
after flashing the community build i cant boot my device in fastboot mode, it wont start the recovery or boot the system sucessfully.

If your device is unlocked, flash the recovery.img from fastboot.
You can download TWRP for oneplus 3 from their site.
Rename the downloaded recovery to recovery.img.
And open fastboot in the path of the recovery image.
Use the command:
Code:
fastboot flash recovery recovery.img
Hopefully this helps

managed to fix it the other day, by flashing the modded twrp.. somehow that one worked after that i flashed the 3.26 plus the 3.26 modem ones because if i didnt, my touch screen wont work...
For me, I flashed the twrp from fastboot.
But still the 1+ logo shows when I try to boot in to recovery for 5 sec and shuts down with 2 dots of lights in the navigation button area
The normal boot is working fine. Did flash the recovery using apps like TWRP Manager, Flashify etc. It will show successfulll. But when I try to boot in to recovery, same result.
Please help
