[Q] Screen completely unusable after Autorec - G2 Q&A, Help & Troubleshooting

Hi guys,
I got my brand new LG G2 in the mail today. I was following a guide to root it (which went fine). I then installed autorec to get the TWRP recovery. After clicking the 'to recovery' button in autorec and rebooting the screen is completely covered in colored lines as you can see in the attached picture. From my research I suspect I need the jdi patch for the kernel but I have no idea how to install this with the screen out of action. I'm not even sure if TWRP was installed properly. I would reply appreciate some help with this.

Try to reflash a stock rom with kdz.

I tried to enter download mode to reflash but it makes the usually booting up sound so I don't think download mode is working (of course I can't see anything on the screen). Anything else I can try?

I was just able to do a stock re-flash. It didn't fix the issue

When you say stock re-flash, do you mean through the LG Flash Tool? If you flashed the stock ROM that way, it would replace the kernel and solve the problem. I don't think your stock ROM flashed properly. Once you get it back, there is a version of Autorec with the JDI panel kernel. Here's a link to download the Autorec with JDI patch: https://drive.google.com/open?id=0BxVbJlj3DLzKd2QyQ1Y1Vmh1dTQ

Just follow this method and all will be ok.

[Q] LG-G2 D800 LGG2 Recovery Problems

I bought a phone pre rooted and everything. It was nice, but the problem is I am having trouble changing the recovery on the phone.
For a long time I had TWRP 2.6.3.4. I could not flash any recovery over it. I was finally able to flash TWRP 2.6.3.1 using the same method to get TWRP. At that point I'm still not able to flash a recovery over TWRP.
I just discovered "flashify" tonight where I had flashed the CWR image for the d800. Now I can't even boot into recovery. It acts like I have non. I can boot into android no-problem though.
When I use "flashify" or "Recovery Tools" they claim I still have TWRP 2.6.3.1.
______________________________________________________________________________________________________________________
Can someone please help me.
I too tried flashing CWM over TWRP using Flashify, but it didn't work, it still said I had TWRP. However, Flashify did work to revert back to Stock Recovery.
I still have the backup file of the Stock Recovery, I can upload it somewhere if you want to, then maybe you can install CWM.
I have a D802 myself, not sure if my backup would work with your D800 though. but if you're adventurous...

I was able to get back a version of TWRP following this: http://theunlockr.com/2013/11/03/flash-custom-recovery-lg-g2-versions-video/
Still don't know why I can't get other recoveries like CWR or why almost all versions of CM will fail to flash using TWRP
EDIT
I miss read you post. I thought you had a copy of TWRP. Go ahead and send the the stock recovery as that's one thing I have yet to try..

Well now I'm not sure if it's a good idea. Even for custom recoveries there are different files to download for D800 and D802. I don't think my backup would be compatible with your variant.
If you want CM, try flashing Official Nightlies. I've heard they are stable. I flashed CM11 Nightly with TWRP 2.6.3.4 just fine. You can grab it for D800 here.

Mine never works. I think its a MD5 error or something. I can only get one version of CM running and I think it's 10.2, I assume my whole phone is just messed up. Not being able to flash CM or recoveries.
Try going back to stock and starting over? Did you by chance take the 10o ota? That seems to be causing issues for others.

Recovery Broken

Hey guys,
I have a Rogers p705G. I tried flashing a recovery. However I accidentally flashed one for L3. Now when I go into recovery the graphics is completely messed up and I cant read anything. Before this I flashed Kitkat Prime. For some reason I have lost root. I am trying to reinstall a proper recovery for the L7 so I can properly flash another rom or go to stock. Can anyone please help me with this? Thanks.
Oppiee
Hmm... I think I'd tried a hard reset with the hardware buttoms, if not I'd tried to install a stock room in download mode. Then, you can try it (root, recovery, flashing) again.

download cwm for your device place it on your internal sdcard and download flashify apk from google play or any other marker you may be using. And flash the recovery from the app.

Help the learning noob somewhat LG G2 T-Mobile D8o130b

Okay so i have a few questions here its been a while since i have placed a Rom onto my device the last one was a Sprint model of the G2 and i was able to successfully install CM12 nightly onto it.
With my T-Mobile G2 i had used the once click root application to do so and used auto rec from the app store to install TWRP recovery hopefully i didn't do anything wrong at this point. So now i try to boot into recovery using the power and the down key at the same time but when i did this i was prompted with do you want to reset all data or not and i of course i chose no and booted back home.
Yes i have Super Su with granting access so to solve this minor problem. I had the quick boot application here to boot into recovery but another problem persisted. I cant flash anything over it fails every time and i am trying to flash 5.1.1 cm 12 i think with gapps with 5.1 i believe but in doing so still failed it matched up and everything. I thought that maybe i was trying to flash something that's really not compatible with my phone so i tried to use the same rom but different carriers.
It was cm-12-20150406-NIGHTLY-D801.zip and gapps-lp-20150222-signed but still failed to install the rom? is there something im doing wrong? May i have a tutorial step by step on what to do to successfully flash? and why cant i boot into recovery with the button configuration did i do something wrong with that i just want to so that if theirs a boot load epidermic and i need to use that to restore and see what the problem is? just need help please

There's no way anyone can read that without any punctuation marks or any paragraph order.
Basically, the data reset function doesn't work when you have a custom recovery, that's how you enter it. But the TWRP version installed is usually old, somewhat like 2.7.0.0, so you need to update it before installing any roms.
If you really do have recovery installed when you get to the screen about erasing data just choose yes and yes and it will just take you to recovery. If that's too scary for you then just boot into recovery using an app like rebooter from the play store.
As far as flashing it sounds like you may have downloaded bad files. If you're using your phone to download the roms maybe try using a pc then transferring to your phone. And DON'T flash roms for a different carrier, you're just asking for trouble.

The problem might be that you are on the wrong bootloader so v30 lollipop. As loki and bump don't work on it it will result into an failed flash. What you can do is flash the right bootloader or easily downgrade bootloader and bootstack with autorec for your phone. Read carefully which one you need for your tmobile d801. If there is an loki error then just flash the jellybean bootloader what you easily can do with autorec.

Well you download the right version for your d801
https://www.androidfilehost.com/?w=files&flid=13763
Then you need to install it
Click on the lollipop and let it do its job. If it asks for root then allow it.
It will probably reboot and you are done. Only need to flash then a newer recovery. Also search bender_007 on xda and leave him a thanks perhaps for his app

Well, as far as I know autorec downgrades to jb bootloader, to boot into stock you could find d801 lp modem and d801 lp bootstack/bootloader as it might need kk bootloader

With cm12 I am not sure but the cause could be perhaps the wrong modem, and or bootloader. I also suggest to check out newer custom roms the only cyanogenmod as some custom roms are already running on lollipop modem and caf. CAF is code aurora forum so kinda it will also have changes specifically for qualcomm devices.

Help with AT&T LGG2 .. stuck in mud

Problem: Can't boot into OS on my D800. When booting the screen stays at LG logo and LED keeps flashing green and blue.
Hisotry:
1) Had original AT&T D800 not rooted, no recovery. Got OTA upgrade to Lollipop.
2) Got new phone so decide to debloat to give phone to my wife (on T-mobile)
3) Read xda forums. Downgraded to d80010o using LG flash utility. rooted. installed older version of twrp using autorec. now phone won't boot but can get into download/twrp
4) got into firmware download mode and flashed d80010d using lg flash utility. this time copied new twrp on sdcard and stripped version of rom (http://forum.xda-developers.com/att-g2/development/rom-stock-lollipop-30b-stripped-t3144195) along with dorilp kernel
5) went back to twrp. flashed stripped rom and kernal.
Still no dice. Exact same situation. I can get into download mode/twrp but when booting system gets stuck on LG logo with led slowly flashing.
what am I doing wrong ?
Are you able to get into recovery? With a lolipo ROM you have to download KitKat boot stack or simply download blastgator lollipop ROM patch from here http://blastagator.ddns.net

From what I read in the OP of that ROM, you're supposed to just flash the rom zip, boot up, go back into recovery and flash the kernel.
"To install ROM, just flash the zip! (Note: The zip isn't signed.) My zip flashes everything you need for the ROM to work correctly.
Recommended: Flash @dorimanx kernel after install. My zip includes stock 30f kernel."
Maybe that's the problem?
Click to expand...
Click to collapse
okay.. installed the patch. still no dice. still getting same stuck at LG logo with led flashing.
also dorimanx kernal is installed. still getting the issue. btw i am not married to this ROM. Any AT&T rom will work. I think there is some mismatch of bootloader/kernal/rom and what not.
what things I can check ?
pulling my hair out.
whatever rom I install using twrp it gets stuck on LG logo. i think i see some message about not being able to unmount /system (but rest of install succeeds).
only way I can get back in OS is to use LG flash utility and flash d80010d or d80010o which basically wipes away everything (recovery, root etc).
assuming I am on stock d80010d, can someone please give idiot proof step by step direction (do i need to check modem version/baseband/bootloader/radio/recovery versions or something to make sure it is compatible ?)

Ok flash back via tot to kitkat and take ota to lollipop. Then use autorec v2. *Do not use the twrp thats comes autorec as it does not flash roms* flash a BUMPED twrp using twrp. Then install your lolipop rom then afterwards install the dormainx d800 lollipop patch just for safe measure but it should work without flashing it.

Yeah it can be rooted. Download stumproot and install it, follow it thru the steps and do the brute force root. Takes a few minutes but it works. I've done it on stock a couple of times. Get autorec v2 on playstore.

i just read that stumproot is not supported anymore..
Actually instead of stumproot, use srk tool to root stock lollipop. I have had success with that.

How can I Install CM in Bootloader Mode?

Until today I had the impression that my LG G2 was done.
You see, a year ago I had this problem with an update, I carry the phone to my carrier as was under warranty, the Fixed the problem but after that I couldn't boot in recovery mode.
No Power and Volume Down or Up Working, nor the 3 times power combination and then I've just came across this boot into bootloader instructions that I didn't know about it.
Code:
Bootloader: With the device powered down, plug in a USB cable while pressing Volume Up.
Which works like a charm.
So can somebody please point me in the right direction to Install CM13 in bootloader mode?
Best regards
you can't, you can only flash a stock rom in download mode

steps are like this.
you are on KK, you need to search for files as that variant i dont know..
you must root phone and install custom recovery
so cehck here for root..
http://forum.xda-developers.com/showpost.php?p=63327417&postcount=4
when you rooted. then proceed to install twrp. use the same link above and look in recovery
click on recovery.. remeber you are in KK so use the one for kitkat dont use Lollipop.
when you find recovery install it..when you have it installed. update it with this one
2.8.7.3
http://forum.xda-developers.com/lg-g2/development/twrp-twrp-2-8-0-0-kernel-f2fs-tools-t2898705
install bootstacks for your variant. 5.02 KK bumped.
http://forum.xda-developers.com/lg-g2/development/lg-g2-bootstacks-t3173715
then you need to find a flashable rom in zip format.. for d805. lollipop. once you flashed it and are in stock lollipop
then find root for lollipop use the links above , i thnk theres root for LP.
when roo is rooted then go to playstore and download autorec for lollipop for your variant..
install and install twrp.. update it with 2.8.7.3 thermal one..
then install hybrids bootsacks. for your variant
http://forum.xda-developers.com/lg-g2/development/boot-g2-hybrid-bootstacks-t3183219
when installing hybrid.. reboot from recovery into recovery again to take effect ... then flash rom and gapps for cm13.
Already rooted. Will check the instructions, overall the one about the recovery...as I said before I don't have a recovery options, when I install TWRP and try to reboot into the recovery mode the phone just reboot.
I believe you gave me the instructions to fix this, fix the recovery, will follow your instructions and will be back.
Thank you for your time.
If it doesn't work try to install the stock kk again and do all the above process again
