[Q] HELP!! No recovery - G2 Q&A, Help & Troubleshooting

HELP!! i tried to use the TWRP app manager to install the latest version. Everything said successful but when I try to go into recovery screen is blank. I also tried to adb the recovery but for some reason i can not get to the # prompt to install the recovery.
I can hold down the power button to reboot my phone and everything works but i would like to be able to get into recovery.
Please advise.
thanks in advance.
EDIT: i was able to use flashify to flash recovery. All is well. May do a clean install now to clear up all the crap i tried to do.
Thanks anyway.

Flash roms from "rom manager"

Is it possible to flash roms directly from Rom Manager without having to start via recovery?
My question is because I cant start my phone in fastboot, recovery, bootloader etc. The screen turns all black if I try anything.
So in Rom Manager there is an option "Flash Rom from SD-card"...pretty much the same that you can see in recovery from clockworkmod. And if I click on it, then I can wipe data and cache also.
Is this a way to flash roms for me if I cant make it to recovery or start the phone in fastboot?
Yes you can flash roms directly from ROM Manager, that is how I do it atleast
nice, will test this! if it doesnt automaticly boots in recovery for the flashingprocess? Or does the rom manager creates a own recovery maybe?
It boots into Clockworkmod recovery I think

Yes it did! and cant boot into that!! Really this is a annoying thing for me!
And I cant run unrevoked again either because I cant boot into HBOOT, so cant install the android bootloader interface. AAAAHH!
Try installing a recovery from rom manager. If there is some problem with the original recovery, it might help. This works by placing the recovery image as 'update.zip' under your sdcard and rebooting. That will her flashed and HOPEFULLY you will have a working recovery.

Ensure you have the update.zip directly under your sdcard and go for a normal reboot. It should flash it and take you to recovery mode.

Have that, and have tryed different versions on the recovery, still only black screen for me when trying this!
Have you tried pressing the power button when in the black screen? I was caught unawares when the recovery mod boot and stays in the cloclworkmod image and not go to the options. I have to press the power button to reach the recovery mod options. I have run out of ideas, sorry.

Thanks for the effort! Have tryed it like 100 times, but cant make it into recovery! Have to take the battery out and restart the phone in normal mode. Thats all I can do, and have tryed all different ways to make it into recovery.
(from rom manager, voldown+power), restart-->recovery, restart-->bootloader)
same results every time...maybe works if I get a new battery or new sdcard or something!

I always find zedomax's videos to be extremely helpful for visuals. He also shows how to load custom roms.
http://forum.xda-developers.com/showthread.php?t=1997227
You'll need to download a recovery program like Clockwork Recovery or TWRP. Both have official websites with the latest release of their recovery programs. Just Google them.

Thanks for the reply, I have TWRP installed, so do i just flash the downloaded rom as per normal and use TWRP? Is there an option in TWRP?
Thanks!

Yeah, so for example. Download CleanROM which is pretty much a stock ROM and all functions of the tablet seem to work that I've tried so far, GPS, WiFi, Camera. Haven't tried HDMI or Audio port yet. Microphone works too.
http://forum.xda-developers.com/showthread.php?t=2113048
Once you download the .zip file for CleanROM to your tablet, it will be in the Downloads directory under the directory /sdcard/0/Dowload.
Then reboot in to fastboot by holding down the volume +/- at the same time along with the power button held. Once you get to the fastboot screen, use the volume rocker until you see Recovery Mode, then hit the power button. This should put you in to TWRP which you said you have loaded as the recovery program. I have Clockwork, it's just a different recovery program, but I've used both before fine. Watch this for TWRP and how to make backups. http://youtu.be/EDZ1WAwXvbE?t=1m30s
Normally, I do a complete clean install each time, but I've also been successful loading from one rom to another and not performing the factory reset. As long as you don't perform the factory reset your apps and settings should remain.
However, I'm a person who likes to do a clean install, so I usually wipe all cache options first, then perform a wipe/data/factory reset and load the rom I want. From there, there should be an option to install from a .zip file, that is where you would go to load the custom rom, then select it and let it do its thing. After installing the ROM, I repeat the steps of wiping cache and factory reset after the ROM install is complete, before I reboot the tablet. Once I do all that, I reboot the tablet and let it load.
People say you should perform a backup of your existing ROM/Settings by using the recovery program to do so, that's really up to you if you want to do it, but it does provide a method to restore your prior rom/settings. I don't, because I just got the tablet and don't have a lot of settings/programs installed at the moment.
If for some reason your tablet just gets stuck at the Nexus X when loading, you may need to perform the wipe data/factory reset from Recovery. If you need to do it from the PC, you can load in to Fastboot (power and volume +/-) let it sit there with your USB cord connected and from your PC go to the directory with fastboot.exe and run "fastboot -w" to wipe. You will lose all your settings and programs just like when doing the wipe through recovery.
Hope this helps. Note, some ROM's suggest loading GApps, I haven't messed with those ROMs yet, but imagine it just requires installing a 2nd .zip file after installing the rom .zip file with recovery.
ah that's how it's done. Thanks for clarifying this DizoA, that's really helpful, appreciate it!

Can't boot into custom recovery

Hey all, trying to flash CM10.2 on my G2 and I'm not able to boot into a custom recovery. Here's how I did everything.
Rooted - all was successful as far as I can tell. Was able to install Titanium backup and backup files and allow root.
I downloaded ROM Manager and installed CWM. When I went to boot into recovery, i get the error with the Android a red triangle exclamation point above him. So I tried to switch to TWRP through Rom manager, no luck. I tried to 'flash' TWRP through the command prompt and download of the recovery file, no luck.
I saw somewhere to download SuperSU, so I did that and tried again, and same issues. When I 'cleaned' SuperSU, uninstalled and reinstalled it but this time chose 'use custom recovery' - it tied to reboot into recovery, saw a standing up right android with a spinning icon, but then went to the same error.
Obviously I'm missing something somewhere. Can't figure out what.
Thanks for any help!
Don't use rom manager. Either use adb and push the recovery or use the app flashify to install the recovery. There are many threads ids the development sections on how to install recoveries

Thanks, Is there a way to undo what I've done from rom manager? Because I used adb to push the recovery and still had the same issue, and using flashify to flash the image doesn't seem to work. Booting into recovery just gets me to stock recovery asking 'do you want to factory wipe your device'
Edit: When I boot to recovery from within flashify, it gives a 'boot certification error' upon booting

Are you using a recovery that has been Loki'd. The G2 needs this to by pass the bootloader. By that error it does not seem you used the correct recovery file.

I used the one from here - http://forum.xda-developers.com/showthread.php?t=2449670 - 2.6.3.3 and just flashed it with flashify most recently. But I was having the same issue when I installed it via adb and 'option 1' as shown there.
Yeah, when flashing that recovery image using option 1, I still get "secure booting error - boot certification verify" after I reboot into recovery
Huh, I got it.
Reading this post here - http://forum.xda-developers.com/showpost.php?p=48118278&postcount=567
Someone else was having the same issue as me. The newest recovery gave him that same error. Flashed 2.6.3.2 and it worked fine. (So far)
Glad to hear. Good Luck.

[Q] Tried Installing TWRP & Now Lost Recovery

Ok so I could use some help. I've successfully rooted & flashed recoveries/roms on my older android phones (Droid Charge & Galaxy Nexus), but I'm having some trouble with my LG G2.
I've followed the IOroot & have root on my 980 but I cannot, for the life of me, get TWRP installed on this phone. I've tried Flishify, I've tried Clockwork Mod Manager, I've tried downloading & using a terminal in manually install it....no luck.
Clockword Mod Manager said it flashed a CWM recovery, but I would get the default standard recovery (no good for flashing roms). So I tried the terminal & typed the code exactly...then I lost recovery entirely. Now when I try to boot to recovery I get an LG screen & a Secure Boot Verification Error - then I have to do the Power & Vol Up to reboot the phone. I then tried Flashify, same results.
I downloaded Root Browser & verified that all my files for TWRP appear in the SDCard folder, so I don't think there should've been any issues w/the terminal, but that's where the trouble started.
Does anybody know how to regain recovery or how to salvage a custom recovery on 24A?
Much appreciated.
Thanks

How did you install cwm?
There's only two ways to get cwm on 5360
Temp cwm
Flash this in stock recovery every time you need cwm
Perminant cwm
This is built into a custom kernel & replaces stock kernel & recovery
If you chose the later it's most likely the kernel you
flashed is not compatible with the rom/file system you are using
More information about what you are using & what you did is required
If all else fails flash stock rom via odin and start again
