LS980 can't install recovery - Sprint LG G2

i'm trying to install a twrp recovery on the Sprint G2, but for some reason i can't and i can't figure out why,
i had 5.0.2 running and i couldn't root it with "one click root",
so i downgraded it to 4.2.2(LS980ZV8) and rooted it with ioroot25,
i installed the twrp-2.8.6.0-ls980 recovery with terminal emulator using the "dd if=/sdcard/twrp.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery" command,
it went through fine but i couldn't enter the recovery, it would just normally boot the phone instead of entering recovery,
then i installed the "twrp manager", it wouldn't detect the installed recovery, so i installed it again using the manager (twrp-2.8.7.0-ls980.img),
it went through fine but when it asked me to reboot into recovery it wouldn't reboot after i pressed "yes",
so i tried to do it manually and still couldn't enter it, so i ran the manager again and it doesn't recognize the recovery it just installed, and i can't reinstall it because it gives me an error that "i already have it installed or another error have occurred",
i though that i might need to downgrade the modem but my modem is already v8 and it enters the "download mode" just fine, so i don't know what to do now, it's my first time modding the g2, help please

ok so i just figured out that to enter "factory reset " i need to press "power + volume up" not "power + volume down , release, repeat" like most everybody says,
either way i can get into the factory reset but after pressing the powerbutton 3 times i get a black screen for about a minute before i can boot the phone again,

i used flashify to install the recovery image and it worked

[Q] cant access the recovey thing..

'hey guys/girls.
Im new at installing custom ROMS and all that.
I got my desire rooted with unrevoked 3.0 and it worked fine.
I installed a custom ROM and it worked fine,but i didnt like it so I tried a new one.
I can´t remember the name of it but I didnt like that either. Again i found a new ROM i´d like to try but when I turn off my phone and turn it on again trying to get to Hboot/recovery mode or what its called nothing happens i just stay turn off until i remove my finger from volume down buttom, then it just start then phone normally.
Do any one know what to do?
There are a couple of ways.
Way 1
1) Turn off your phone
2) Hold vol down + power until it loads the bootloader
3) When it's finished checking SD card, move to recovery using volume keys and press power to select recovery
4) It should load into recovery
Way 2
1) Have the Android SDK installed with the platform-tools downloaded and working
2) Make sure you plug your phone cable in your phone and PC
3) Open up command prompt or terminal (depending on your OS)
4) Type "adb reboot recovery" (no quotes) and it will reboot to recovery.
i have similar problem, cant access recovery anymore. that happened after installing a custom rom (leedroid). when i try to access recovery phone just hangs up on that red triangle. to turn it on again i have to pull of the battery. btw, phone works normaly itself only problem is that i cant access recovery to install some other rom :/

Click to expand...
Click to collapse
The red triangle is the stock recovery, so you're actually in recovery there.
Download a recovery and read this. Should get recovery back on your phone again.
but i had normal recovery i installed dozens of custom roms :/ and now phone just stucks in that screen with phone and triangle :/
How the hell can you install custom roms with the stock recovery.
thats the point, i had normal recovery and now i cant access it im using custom roms from the times desire was released and now almost after a year this **** happened :/
Ok... 2 posts ago I linked you to an article that can get the a custom recovery back onto your phone.
can u explain me info in that link a little? what .zip file do i need and where to get it? and WTF is terminal?
1) Download Clockwork Recovery or if you have PVT4 download Amon_RA (GSM)
2) Put it on your SD card
3) Download terminal emulator from the market
4) Type "su" (without quotes) and press allow when it comes up
5) Type "flash_image recovery /sdcard/recovery.img" (without quotes) and it will write the file to your phone.
To check which PVT you have, boot into bootloader. Turn off phone and hold vol down + power.
installed better terminal emulator pro. downloaded img, renamed it to recovery, inserted it to sdcard in terminal typed:
su (enter)
flash_image recovery /sdcard/recovery.img (enter)
and terminal says:
flash_image: not found
Did you put the img into a folder?
no, in the root of sd card
Weird. I don't know. Just tinker around with it. I tried it once and it worked for me. Check spelling, check in a file manager to see if the file is there.
i think i get this. thing is my rom does not have flash_image. now looking how to get it.
yep, there is no flash_image in system.
Are you using the new Sense ROMS/Gingerbread? If so 'Fast Boot' mode will screw with getting into recovery. I have to hold down volume while replacing the battery or turn off fast boot from within settings....
OFC if you have no recovery image anymore this won't help one little bit
KYI
yes im using new leedroid gb. i turned off that fast boot, its not that :/ now trying to push flash_image through adb, but it says "failed to copy....bla bla bla...: out of memmory" getting little desperate
If I was you I would back everything up. Contacts, SMS all that good stuff. I would then use an RUU and get the stock rom back on and just root that. Could of done it by now really.
Ok 2 problems:
1. to the topic starter. The reason you can't access recovery is that your rom uses fast boot up(sleep mode). When this is activated the phone doesn't really shut down when you tell it to, so it also cannot actually enter recovery or fastboot. Just turn it off in the settings menu and you'll be fine.
2. to Drunk Moose.
You have the original htc-recovery installed. I bet that you rooted back before unrevoked, and you probably have been using fakeflash since then. Try making rom manager dl cwm and choose reboot to recovery from rom manager. It should enter clockwork mod. If that is the case, this means that your phone have a modified version of the stock recovery, which allows test-keys. if that is not the case, and you still get the triangle, you somehow overwrote your recovery with a stock one.
Either way to fix this, you need to replace the recovery image with a cwm one. This can only be done in 2 ways for the desire:
1. Use unrevoked even though your phone is rooted and it'll flash it using a known exploit.
2. run alpharev to gain s-off. When you have s-off you will be able to flash the recovery through fastboot or from the system like described by meaple.
The reason it doesn't work for you when you do like meaple descriped, is that the commands tell the phone to use a custom binary called flash_img and passes it the parameters "recovery" and the "recovery.img" file. Then the binary will tell the android system how to write the img file to the recovery partition(it cannot do this entirely by itself). However this bynary is very unlikely to be included on your rom(like you figured out yourself ), so you need to place it somewhere you can access it from the terminal. And even if you had had the file, you wouldn't have been able to do so, as the recovery partition is write-protected doing runtime, when you are s-on.
So I'll recommend that you do one of the 2 mentioned solutions(I'll be glad to provide further help)
edit: and for god sake don't just flash a ruu every time you are in doubt... There are almost certainly an easier solution, and by doing s-off, you can avoid ever having to run a ruu again, as you can restore the system 1 partition at a time if you feel like it.(sorry this was not directed at you but people in general, as meaple just suggested doing so)
in fact i was just trying to use unrevoked bu it stucks on bootloader, tells to check for drivers, despite the drives is installed. :/
p.s. and yes i have rooted my desire almost a year ago there was no unrevoked
any other suggestions? or just try to install ruu?
and about the rom manager, it gets me to the same red triangle. btw the recovery was fine till i installed leedroids rom about a month, and i noticed it only few days ago, when i tryed to update my rom.

Rom Manager won't enter into recovery

Hello
I am now rooted, I have my custom rom and full wipe on SD not extracted of course.
Installed the Rom Manager, flashed the clockwork recovery...but doesn't matter what I do it won't enter into recovery.
Even bought the droid bootstrap, tried it manually and still the same.....the triangle and ! shows every time.
Please help me...what should I do? what is it that I'm doing wrong?
Try shutting down the device and starting it up by holding the volume down key at the same time. When the bootloader shows, navigate by volume keys to recovery.
Try flashing recovery from fastboot

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.

Can't flash new recovery or exit bootloader

Hi, I use a Asus Zenfone 2 ZOOAD
A few days ago I decided to flash the CM13 (Marshmallow) ROM on my phone. My phone is rooted. Anyway, when I tried to enter the recovery mode using the bootloader screen ( I selected "recovery mode" by using volume up and down) I couldn't do it. So, I decided to use the adb method. I'd already done it to put the Xposed Framework. So I connected my phone to my Windows 10 laptop and tried to enter recovery. Same story. It got stuck on the bootloader. I even tried flashing the custom twrp recovery; twrp is getting installed (or so it shows on the command window) but I can't enter the recovery mode. Worst part is I can't even boot into my normal screen. When I connect my phone to my laptop, it's detected but when I try to use adb it says "device not found". I am able to execute the fastboot commands though. But all in all, I can't get out of the bootloader.
When you are in bootloader you must choose recovery then agreed (ON OFF Button) then when it reboots : "VOLUME UP + ON/OFF" *click several time*
Here it is : http://forum.xda-developers.com/zenfone2/general/asus-zenfone-2-flashing-recovery-mode-t3096596

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.
