Whichever rom doesn't give you a security error :) I've always used stock ROMs on the g2. If you like aosp roms then my favourite one (on the oneplus one) is blisspop. But read carefully, be aware of your partitions and what's compatible with what. If you not sure just post back here.

Hi guys,

I've been on PA for a while now, made the step from KK to LP and was running an early march build for over a month when suddenly my phone decided not to boot anymore. It booted till the PA boot animation but that animation just kept animating. Long story short, I had to revert to stock rom, rescued my phone using linux, tried the first 5.1 nightly and ended up with the continuous boot animation again. Reverted to stock again and I am now on a KK rom. As you'll understand, it's rather frustrating to have a phone with which I hadn't done any rom-related stuff for a month and which was running rather smooth and suddenly it doesn't boot anymore.

The last few weeks I've been reading a lot of topics trying to understand the lg g2 story. I was somehow missing the big picture, I knew there is a difficulty going on with the JB/KK/LP bootloaders but I hadn't had a clear image until I've just found this post;

http://xdaforums.com/showpost.php?p=59965746&postcount=1226

My phone is one and a half year old now and I'm running custom roms for all that time but I didn't know how the bootloader story actually went until just now... (I do follow the PA threads but it never became quite clear to me)

Now I would like to return to LP but I'm not sure which bootloader I'm running, since I'm extra careful because of the boot animation loops, I'm going to take small steps to get back to LP.

Is there a way to find out which bootloader I'm running? What is the safest way to go from where I am now to a LP rom?

Thanks in advance
[G2 Q&A, Help & Troubleshooting] Art Vanderlay:
That guides a really roundabout way of fixing it. I've been thinking of making a video guide of security error/secure boot error. We can also make an FAQ. This thread op needs updating. A lot of changes need to made in this forum.
[G2 Q&A, Help & Troubleshooting] bender_007:
Or automatic way :). I like creating automatic stuff.
[G2 Q&A, Help & Troubleshooting] Art Vanderlay:
So you reverted to stock kk now? That means you're on the kk bootloader. If you want to run most aosp roms like pa you need to be on the jb bootloader. Therefore you should use kk autorec (which puts you on the jb bootloader) and then flash pa.

Here's a similar thread to that the one you read that might help :)

Bender's choice. I personally run ubuntu natively with windows in VMware. But whatever the doctor ordered..
[G2 Q&A, Help & Troubleshooting] bender_007:
Slax is based on Slackware <3, my favorite.

+1

+2 - slax has a lot of modules, you can build it very easy on your own (or put addons via module directory)

+3 it's waaaaay faster and small (it was around 150 mb some time ago, now it grew)

+4 Some people which didn't have success on ubuntu had success on slax (and other linux flavours), I prefer minimalistic "a' la slitaz"

+5 boots much faster etc etc etc

I just flashed the efficient kernel ( http://xdaforums.com/lg-g2/development/kernel-efficient-kernel-1-0-0a-aosp-t3042534 ) trough twrp and now, my phone doesnt boots. I can only enter download mode, but even then, white lines appear on the screen and my phone isnt recocgnized by the software on my pc (lg mobile support tool and lg pc suite). I cant boot into recovery, and when trying to normally reboot, the logo gets darker and the screen turns white and then black after 1 minute.

I tested it. It works. Just make sure you are running it as administrator. Afterwards I recommend you to use autorec for LP. Afterwards you can stay on this bootloader if you want to go with stock based roms. If you want to go for AOSP roms, downgrade to the JB bootloader.

[G2 Q&A, Help & Troubleshooting] karazz:
Thanks, that was exactly the topic I should've found myself. Sorry for that.

The only strange thing that remains, any idea how it could've happened that I powered down my phone, put in on the charger for the night and tried to power it up in the morning and it would only loop the rom boot animation? I hadn't changed anything rom/kernel/partition related before I powered it down... I know that's in some way the price to pay when playing around with custom roms, but I would like to understand what exactly happened there and how I can prevent it in the future...

Regards
[G2 Q&A, Help & Troubleshooting] karazz:
Strange things keep happening (probably just me not understanding things). I'll try to explain what happened

- started on the kk factory image

- installed twrp 2.8.6.1 (blastagator's bumped version)

- installed pardus rom

- found this topic

- ran autorec (which installed older twrp version)

- installed twrp 2.8.6.1 again (using flashify)

- read a lot and thought it would be more safe to go to twrp 2.8.6.0 because that one is loki'd

- tried to flash twrp 2.8.6.0 but ended up with no bootable recovery, phone showed fastboot mode

- flashed 2.8.6.0 through fastboot (fastboot flash recovery recovery.img)

- ended up with a boot verification error every time I try to boot into recovery

- ran autorec again

- installed twrp 2.8.6.1 again (using flashify)

Quite some things are unclear to me. Since I ran autorec, I should be on JB bootloader. Why can't I flash the 2.8.6.0 twrp recovery? And why didn't it boot into recovery before, but showed fastboot? Is there also a major difference between loki and bumped recoveries? I searched for it but I am under the impression that when the recovery is bumped, it also supports loki.
[G2 Q&A, Help & Troubleshooting] Sunandroid:
Be aware: There are different versions of TWRP. The one for LP flashes the KK bootloader, the one for KK flashes the JB bootloader. So make sure you flash the KK one. Otherwise you will still be on KK bootloader after autorec.
[G2 Q&A, Help & Troubleshooting] karazz:
So, if I update my recovery, my bootloader will be updated as well? I thought that would only overwrite the recovery. What actions cause the bootloader to be overwritten?

And how can I see the bootloader difference between the different TWRP versions, do I have to go through the changelogs?

LG G2 D802, NO signals for WCDMA

Hi All,

Yesterday I bought an LG G2 D802. It seems it is Chinese/hong kong variant. The issue is when I switched the Network to WCDMA there is no signal and I am unable to connect to 3G. The signals are full in GSM mode and EDGE is working fine. Can anyone help to sort this is out? I am in Pakistan and here 3g frequency is 2100Mhz. please see attached images for proper build/kernel etc. I am not sure is this due to china Variant as I guess it is Chinese variant but not certain about it. while googling I went through Time zone etc stuff in china that won't work other than china but I am not clear about it. thanks and cheers.

PS: it only shows GSM/WCDMA in network selection where as I Have optimus g PRO e988 which shows GSM/WCDMA/LTE and when I switch my G PRO to WCDMA it works fine and I can connect to 3G (In the same room, confirming it is not carrier's signal issue).

Other Variant G2 D802 Rom

One thing more, can I flash any other variant rom on my G2? like If I want to install D802 UK variant rom on my G2 will it work? and will this also change the Baseband version? as it seems may be baseband version is the culprit here.
[G2 Q&A, Help & Troubleshooting] Sunandroid:
No, no. You missunderstood it. Autorec changes (as you said correctly) the bootloader. What I want to tell you is that you should be aware of the different versions of AUTOREC.

To look what bootloader you have it's best if you try to enter the recovery with the button combo. If you have to press vol-&power after the lg logo shows up, you have the JB bootloader. If you have to press vol-&vol+ inestead, you have the kk bootloader.

Hello to everyone taking the time to read this. I am brand new to flashing roms and I am having a major problem that I can't seem to find any information on how to fix .

I just got my D800 and rooted it . Then I loaded TWRP and made a backup. After that I wiped everything except the sd card. I then flashed CM 12 and gapps and that's when the problems started .

The only google app on the phone was the play store and it would not load and I couldn't add my google account to the phone anywhere. I was also not able to boot into TWRP. I eventually tried enabling debugging in the cm settings, clicked on the root access settings, and selected the cm setting that allowed me to boot straight to recovery . This worked, and I then wiped everything again and next I flashed another version of cm 12 and the newest gapps.

Now I am stuck on the CM 12 initial setup process , because I am not able to get passed the error message "Unfortunately, google Play services has stopped". I do not know how to get back to TWRP without enabling those settings that seemed to have work after my first failed attempt. Any help that I could get with this will be greatly appreciated . I have given out all the information to the best of my ability and if more information is needed please ask the question in the most simplest form since I am a total noob. I was also wondering if I need flash a new modem when flashing CM 12.
[G2 Q&A, Help & Troubleshooting] Sunandroid:
First of all what android version were you running before installing CM12? 4.4 KitKat, 4.2 JellyBean or 5.0Lollipop?

Second: how have you got TWRP? And what version of TWRP is installed right now. If you used autorec, please post a link to the thread where you found it. You can enter TWRP this way: shut down the phone, wait 10 secs. Then hold vol- and power, release and immediately press the buttons again when the LG logo shows up. You will then be asked if you will wipe your data. Confirm with the power button twice and you will enter the recovery. No data will be lost, no matter what it says on the screen. ;)

It happened before the other day, and when I went to a tech store, he just used the buttons to power it on. He told me he did a hard reset, but he probably means something else since none of the data were lost, just took more time to reboot and that's it everything was the same.

[G2 Q&A, Help & Troubleshooting] Art Vanderlay:
Lets give all this one last shot, I'm sure we can fix this if we do everything right.

Download your KK kdz here. Pick the right one for your phone model. V20 are KK and V30 are LP. Run a CSE flash with it.

Root your phone and run kk autorec. Flash TWRP 2.8.6.1 through recovery. Nevermind loki, bump works on JB bootloaders.

Now wipe cache, dalvik, system, data and flash PA and these gapps.

Flashing a kdz gets rid of any software issues you might have. So if you still have issues after doing that then I'm not sure what the problem could be.
[G2 Q&A, Help & Troubleshooting] karazz:

[G2 Q&A, Help & Troubleshooting] Sunandroid:
To be honest, I can't really tell you what to use. Often the devs themselfes don't know which baseband to pick. Personally, I just stick to one (I think it's the AOSP-modded-kk one, atm) and flash another one if it doesn't work.

Most people recommend the KK Baseband. Theoretically CM ist still based on JB sources. So a JB Baseband would be neccessary. But most are sure, that a KK one is the right one. If you ask in the CM thread, everyone tells you to flash the KK Baseband, but no one wants to post a link because it might still not be working after flashing it.

So the only advice I can give you is to try the stuff out. Here are a few JB ones.

I'd recommend you to try these out: The ones by dr87. Here you can find the proper KK ones by cloudyfa. I recommend you to try out the ones found on the last two links first.

If you get it working, I'd really appreciate it if you'd report, what worked for you.
