installing a custom recovery

Hello, I'm right in between an illiterate and a noob when it comes to android Xd.

My device is LG G2 D802 30b running stock lollipop 5.0.2 rooted.

I've been trying to install a custom recovery like CWM or TWRP. every time i reboot to recovery I get the secure booting error.

Tried autorec, the flashing button was missing (apparently my supersu version 2.65 doesn't support it)

I tried rerooting to get a 2.46 supersu, it didn't work.

Is the boot loader locked?!

What are :loki, bootstack ,bump? and which one is right for my device?

how to fix this?

thank you in advance
[G2 Q&A, Help & Troubleshooting] Sunandroid:
There is at least one link in my signature that could help you a lot.

For TWRP: Get autorec from the playstore (there are different ones, but the one from the playstore (for your d802 of course) is the right one for stock lollipop).
[G2 Q&A, Help & Troubleshooting] h4mid9:
Hi

Is there a way to reduce the vibration to its minimal

Amount?

Also i checked the setting but it was not enough!
[G2 Q&A, Help & Troubleshooting] Doppler Effect:
Thanks for answering. I have tried autorec, as i said it didn't work do to superus incompatibility. the developer recommended installing supersu v2.46, the problem is that I have no idea how to downgrade from 2.65. I've tried rerooting and flashing su2.46 but it won't change!

I think I have TWRP installed with Flashify but i keep getting secure booting error, any idea on how to install/put/flash loki?? or another bootloader bypass/unlocker??
[G2 Q&A, Help & Troubleshooting] Sunandroid:
Did at least installing the bootloader work with autorec?

I never had any issues with autorec btw. So imo it's pretty weird that it isn't working for you...

If patching down the bootloader worked, youu could flash blastagators TWRP through flashify. Otherwise you'll just get the secure boot error again.

Have you read my post about the software on the G2? Do it. Maybe you can elaborate an answer yourself then. That's always easier.

If you can't: Can you tell me what exactly doesn't work with autorec.
[G2 Q&A, Help & Troubleshooting] KoronadalKid:
Do you guys have a download link for the PowerG2 3.0 ROM? The download link posted on the thread does not work anymore. Thanks
[G2 Q&A, Help & Troubleshooting] Doppler Effect:
It is a known issue with the app. If you type "(D802) LG G2 AutoRec-Lollipop" in google play, you'll find in the description the developer talking about it.

He referred to this solution that I tried.

Maybe I wasn't doing it the right way, it didn't work, the supersu won't downgrade.

I haven't read your post, if you can refer me to it pleas do.

The flash button in autorec was missing so, no patch was installed.

I have a couple questions:

How to downgrade supersu?

How to do what autorec is doing, using adb?

Much appreciated :)

Thank you all guys!

I've unrooted the device from suppersu, rerooted it with (one click root v1.3) the other one didn't work.

That rooting software came with suppersu 2.46, then I used autorec, it worked!!!

I now have CM13,

small problem though, after flashing CM13 I downloaded suppersu from playstore, it won't update it's binaries and i can't access recovery mode :D
[G2 Q&A, Help & Troubleshooting] bender_007:
I suggest you flash twrp using flashify and then via twrp flash the updated supersu package

[G2 Q&A, Help & Troubleshooting] El Niche:
Hello,

I have a few questions I'm hoping someone will clarify. I've always owned a Nexus but bought a G2 bc I broke my screen. I have the D800 variant running ATT stock 5.0.2 LP. I want to try out both Cloudy and Dirty Unicorns. Can someone please confirm the steps Im taking are OK as even though I've read about it, these bootstacks thing has me a bit confused:

1. Root with One Click root 1.3v

2. Auto-rec to get TWRP

3. Go into TWRP and flash Blastigator new TWRP (does this step make sense?)

4. Do a backup of current ROM

5. Reboot, Flash 5.0.2 Bootstack with KitKat (Bump) bootloader for D800

6. Reboot, Clean Wipe, Reboot, Flash Cloudy/D.U. + Gapps.

Question, if I flash one of the ROMs, make a backup I can just switch between them using the Nandroid?

If I get the LG and blank screen, the only way to access the phone is with a OTG and USB drive?
[G2 Q&A, Help & Troubleshooting] Sunandroid:
Yeah, makes sense. Especially step 3. ;D

Take the autorec version from the playstore.

Yeah, you can switch between the ROMs using the nandroid. But: I guess you won't do it many times. Backing up and restoring data takes quite a lot of time.
[G2 Q&A, Help & Troubleshooting] El Niche:
Thanks for your answer. Then when switching from Rom to Rom it is not necessary to do the full TOT KDZ restore to KitKat.

Thanks for your answer and time. My last flashing experience outside of a nexus device was pretty much in 2010.

No, as long as you have a working download mode, it doesn't matter what's installed. But if you wanna switch between a custom rom and stock, I'd go with the nandroid way you mentioned before.

A working download mode should always be the the case and even if there is not, there are ways to get back to stock if you need it.

[G2 Q&A, Help & Troubleshooting] tekweezle:
That would be the logical location but seems like the ability to add or edit APN is not there.

Funny thing is that I believe it was there when I got the phone from Freedom pop because there was a freedom pop APN. But since then, the phone has been Ota updated to a newer version of the os.

Odd thing is that It works fine on Freedom pop even without any freedompop specific settings.

[G2 Q&A, Help & Troubleshooting] mgmgb:
Today my phone started acting really strange, it would scroll from the home screen to the other pages on it's own and open apps on it's own. It hasn't been dropped or come into contact with any kind of moisture, always in a protective case etc.

I updated to kitkat a couple of weeks ago and although I wasn't impressed I didn't have any problems until today.

I decided to do a factory reset and that has stopped the scrolling and opening of apps but now the knock on feature doesn't work, knock off does however.

I tried to use one of my back ups (most recent just before upgrading to Kitkat) and it hangs at 15% so I'm stuck with what I have, basically an out of the box phone which is fine, I'd just like to have the knock on feature back.

Any ideas?

It's a tmobile G2.

New phone already rooted?

So I just picked up a Verizon G2 from Costco, rather spur of the moment.

Get on XDA/Rootzwiki to see if anything negative about the phone like locked bootloader, wife has Sammy S4 and locked bootloader :rolleyes:

Nothing bad so I let the OTA to Kitkat roll

Haven't even connected it to USB yet, look in About Phone > Status > Rooting Status > Rooted???

Hi, I had touchscreen issues and had all the phone front replaced officially at LG. I received the phone repaired something like 2 weeks ago and the other night I noticed some white light coming from the side of the screen. I looked closer and noticed the screen (just the glass part) is coming out, I can see that it's a little bit higher than the plastic frame and feel the "screen sharpness" when I touch it with my finger. I don't remember this happening earlier, is this normal? Should I send it back to repair shop? Thanks

Try pressing the glass back into the frame. If it stays there, leave it as it is. If it doesn't and you can get it fixed for free (warrant on a repair), I'd go the way and send it back again.

I've had that too. You don't really have to worry about it, since it doesn't affect your phones behaviour.
