As title says when I flash or install a recovered LG based rom the handset gets into a bootloop. Lollipop or MM doesn't matter.
I see the BIOS type of screen for a few seconds then 3 seconds of boot animation and back to BIOS.
Cyanogenmod 13 based roms work just fine.
background: After receiving MM ota update rooted and downgraded to lollipop. Installed a modem file in the process as well.
Then I decided that I don't like it either. FLashed cyanogenmod straightaway.
Then flashed genesys rom which is LG based 6.0.1.
Still no problems.
Installed xposed framework and the bootloops started.
Then I run the xposed uninstall script, wipe everything and install LG MM rom. bootloop again.
Sorry for the long post. Didn't know which detail is relevant so wrote it all
Any help would be much appreciated as I am stuck with cyanogen...
Try to go back to stock with lgup
lgup doesn't recognize the handset when CM is installed.
Anyway finally found a solution after trying every trick in the book. Basically flashing modem, boot and bootloader solved the problem.
Now I need to find a way to flash xposed framework without bricking the phone.

Hi, i have a strange problem. i have been using alot of roms.changing different roms off and on. but i thought of trying original 187 kdz file. then i rooted it. removed inwanted programes and it was functioning great. but when i wanted to use 3G net,it was not shifting from G to 3G service. i tried alot of methods but failed.
then i installeted cm 6.0.4.5 and tried to install sphinx rom. it booted normally but stuck at setup screen. then started boot looping. i again flashed. but same thing. now i am able to install 4.2.2 but not 4.1.2 some how. 4.2.2 color os rom is working great but not 4.1.2 rom. i have repeated kdz flashing rooting bit no avail.
any advice suggestion.
Hi there guys i bought the sprint g2 quite a while ago and have been dangling with roms for quite some time on it the problem that i'm sharing with you guys arised today.
I flashed the newest version of Resurrection Remix 5.4.6 on it and while it worked buttery smooth it had no sound whatsoever and couldn't auto-rotate so i flashed the lp baseband and zv8 modem on it to see if it remedies that, no solution, so i reverted it back to 5.4.5 with my nand backup, it worked fine until i found out i couldn't d2w when it was working flawlessly before so i flashed(foolishly) the kitkat baseband and this leads me to the problem i'm sharing with you people.
My phone is now stuck in a bootloop restarting to the lg screen again and again, giving me a secure boot error on download mode so i can't use the .tot and .dll stock files on it and i can't seem to get into hard factory reset so i can just get into twrp and flash the lp baseband again and relieve me of this nightmare it also gives me multiple windows drives with one accessible one with an image folder when i go to download mode
[EDIT] fixed it somehow got into recovery and flashed the lp modem, can a mod close this?
Hello guys,
It's been a while since the last time I visited the SGS3 section, over a year ago I remember updating the bootloader in order to upgrade/flash to 4.4.4 which went very smooth and was a success. I gave the phone to a sibling who has been very happy with it for the last year and a half. Lately, the phone has been very unstable with the 4.4.4 KitKat ROM, WiFi doesn't turn on, Bluetooth is unstable, Unstable apps/Force closes. I tried a wipe/factory restore and re-flashed the ROM but the problems persisted.
I did a little research and liked what CyanogenMod is doing and since they are actively supporting the phone I decided to flash CM12.1 and the provided Open Google-Apps, CM12.1 flashed successfully but Open Google-apps refused to install, CWM displayed (Section 6) error which upon research it is common with CWM and the solution is to flash TWRP. I booted with CM12.1 in order to install TWRP Manager through the APK and flash TWRP but it force-closed when it searched for the device model. WiFi was working but Bluetooth was still unstable.
I would like to know what would be the best way to proceed in this case, I would like to upgrade the recovery to TWRP and flash CM12.1 or any other stable Lollipop ROM.
Thanks,
Oscar

I'm currently running my OP3 on Resurrection Remix 5.7.4 (MM 6.01), the phone has the latest version of TWRP and I've flashed other ROMs in the past without any issue
RR has proven to be quite unstable for me, the system UI keeps crashing, which renders the phone unusable until after a reboot so I wanted to flash Freedom OS as that worked quite well for me previously. When I tried to flash the ROM in TWRP the ROM seemed to flash successfully but when I rebooted, only the boot logo showed and then the screen went black and the phone refused to respond at all for about two hours, after that exactly the same thing happened. I managed to boot into recovery and tried flashing a different ROM but the result was the same every time, the only way to get the phone to work normally was to flash RR again/restore from a Nandroid backup, either way, the result is the same, I'm stuck on an unstable ROM and I don't know why, the last time I flashed these ROMs they worked fine, I followed all of the instructions for flashing said ROMs to the letter, I have the latest version of TWRP, etc, does anyone know what the problem could be?
Have you flashed the latest firmware? If not, I think this is why due to you being on a very old version (6.0.1) and as you are not flashing official OxygenOS you are not getting the newest firmware.
Download and flash the latest firmware here:
https://forum.xda-developers.com/oneplus-3/how-to/radio-modem-collection-flashable-zips-t3468628
Pick the right one for the ROM you are flashing (For Freedom OS installing firmware Open Beta 14 - Firmware + Modem under 7.1.1 should be good.)
Note: After you have flashed the firmware the next time you reboot the phone it will appear to not turn on for a few seconds, this is normal while it updates, don't worry
Let me know if you have any questions
So I have a T-Mobile LG G4 that like every other G4 had the bootloop problem when I got it. I sent it to LG and they promptly fixed the issue. My current issue has nothing to do with the bootloop I believe.
Because the G4 wasn't getting the Android N update fast enough and also because I wanted to play around with Android's full potential, I decided to root the phone a little over two weeks ago. The process worked and I decided to install a custom ROM. That also worked. I have installed four or five custom ROMs built on Android 7.1 without issue, or at least without any major issue.
However last night I decided to flash Genysis ROM on Android 6.0 because I wanted to play with Xposed. I made a full Nandroid backup of the CRdroid ROM it had been running and then wiped and flashed it using TWRP. When I installed the ROM it didn't work for whatever reason, freezing up and frequently becoming unresponsive. Over about 30 minutes I managed to enable USB debugging and reboot it to recovery (why I didn't shut factory wipe it from bios I'm not sure).
Now any ROM I try to install doesn't boot up. It never gets past the OS loading screen with the ROM logo. On 6.0 ROMs it says it has optimized the apps but gets stuck on starting them. The Nandroid backup I made does the same thing, even ones I made early that day and one from several days ago.
The backups had that one app installed that shows the logcat while booting up and while I'm no expert it seems to get a loop loading the audio drivers. I don't know if that's the cause or if it's just coincidental, as I've never heard of audio drivers preventing a boot, albeit my experience is with Windows PCs.
If it would help I can attempt to take a picture of the screen while stuck, although the text moves very fast. I can access the TWRP recovery just fine but don't know how to/if you can dump logs.
Any help would be much appreciated! I can attempt to supply an information that may be needed as well.

why not start from 0 and flash latest KDZ with LGUP.
https://forum.xda-developers.com/tmobile-g4/development/h811-kdz-file-t3607807
For sure I'll try that. I'll let you know if it works, thanks!
Follow up- I eventually found the free time to work on this and flashing the kdz worked! I actually had to use LG Bridge as LGUP only found my device as unknown.
Thanks for the help! Back to flashing ROMs for me.
