Stuck on lg logo after rom installation - G3 Q&A, Help & Troubleshooting

My phone was on v30g. I wanted to root it so i downgraded it to v30b and rooted with kingoroot app. Then i installed twrp with Autorec MM. Then i updated TWRP with official twrp app. Until then there was any problem i successfully booted into twrp. Wiped system data cache and dalvik, installed rom. But when i reboot the device, it only shows lg logo that's all, it doesn't boot. I tried 3 or 4 rom but none of them worked. What can cause this ? Any ideas ?

Sometimes this happens to me, all I need to do is do a full wipe, that means wipe all partitions, you will lose all your data so better backup first.

[Q] Stuck in recovery mode bootloop!

Hello everyone,
This is what is happening to me. I was trying to flash Miroslav's Cyanogenmod 11 RC2 with Philz Touch 6.07.9, but none of the recomended methods worked for me, I just got stuck on lg logo bootloop - I really want this rom but it is hard as f**k to flash -. So I tried to go back to CM 10.2.1 and got the "Status 7" error. Very frustrated, I finally used my stock recovery image and it worked fine.
From this point, i was recovering my apps and data using titanium back up and when it finished, a notification asked if I wanted the official system update. I refused it and proceded to reboot. Now the phone boots instantly to recovery mode and show the purple screen of Philz touch. First I wiped cache and dalvik and got the same bootloop. Then I wiped cache, dalvik and factory reset and got the same bootloop. Finally, I formated system, factory reset, wiped cache, wiped dalvik and flashed again my recovery image, and got again the recovery mode bootloop.
Any Ideas? Thank you for your help.
Best regards.
EDIT: I must clarify that when I flash my recovery image, it ALWAYS get suck on a part that says something like "installing android security". I have to press power button 10 seconds to restart but it boots normaly in the stock rom.

When in vain , unbrick your phone again using unbricking guide and use CWM , not all guide is working for the same type of phone . No need to wipe system clean cache watevr **** you were told unless recommended by developer and just factory reset then flash the rom

Thanks for the answer and the advice about factory reset. Yes, I had to unbrick my phone and by the way, still could not install miroslav's cm11 RC3 using Philz touch 6.19.3.
But I have another issue: I successfully got back to CM 10.2.1 but after I restored my apps using Titanium Backup, I rebooted the phone and got stuck on CM logo for half hour. I wiped dalvik and got the same result. Then wiped cache and dalvik and still stuck. What should I do? Flash again the rom? The restored data is from CM 10.2.1 so I don't see any problem....

check again what you restore, user apps will have no problem to restore but system apps will cause incompatibility to the rom and crash it

The phone is good now, I restored the stock rom and from there I flashed CM 10.2.1 just making a factory reset. Plus I flashed adreno drivers and gapps. Once it booted, I restored my apps without sistem data and now the phone works properly.
Thank you Mr.201

Glad it worked, make sure you untick 'system' in filter in titanium backup so that you can only see your user apps .

[Q] G2 Stuck on CM Spash Screen Loop

Hey All,
Here's a basic synopsis of my issue: I just flashed CyanogenMod on my Sprint LG G2. Now when it boots - or attempts to - it hangs on the CyanogenMod Splash Screen with the spinning cyan arrow.
Here's some more detail:
I've been trying for a few days to get this to work, and I'm finally stumped. I learned the hard way about the LS980ZVA radio and how it's not compatible with non-ZVA ROMs, and whatnot, and I've restored my phone using a .tot 3 times. This most recent time I used the LS980ZV8.tot to enable me to flash CM.
Here's what I did:
Restored phone to LS980ZV8 using LG Flash Tools
Rooted using ioroot
Checked Root
Installed FreeGee Free
Used FreeGee to install CWM 6.0.7.4
Rebooted to recovery
Made a backup
Copied backup to PC
Copied CM-11-20140708-SNAPSHOT-M8-ls980.zip to root of internal storage
Flashed said CM-11.zip from 'sdcard' (It was in sdcard/0/ for some reason)
Rebooted
Got stuck at CM screen.
Did some research on Google
Went back into CWM
Cleared cache
Reflashed CM-11.zip from sdcard
Rebooted System
Stuck at CM screen.

Any ideas? I can't figure this out for the life of me. I've read something about flashing the boot.img from fastboot, but I can't figure out how to get into the fastboot on the LG G2, and besides that was for an HTC. If you need more info, let me know.
=====Phone Details=====
Carrier: Sprint
Model: LG-LS980

Did you do a full wipe? I would recommend TWRP recovery over CWM. I've used both, but for this phone I prefer TWRP. There are numerous threads with details on how to install it. If you prefer CWM make sure to factory reset/ wipe data, wipe cache, wipe dalvik cache, then flash your rom. Manually shut down your phone then reboot. I've flashed cyanogen Roms on several different phones and they can be finicky. if you choose TWRP then you would do wipe-advanced wipe- check boot, system, data, dalvik, everything except Internal storage. In same recovery session flash your CM rom. Hope this helps. Oh and I would recommend making a backup in TWRP as well if you choose it.

No I didn't do a full wipe. I'll take your advice and flash TWRP. I've been out of the Android scene for a couple years and I've had more experience with CWM, didn't know how well recommended TWRP was. I'll flash TWRP, make a new Nandroid, then follow your instructions. Thanks. I'll report back.

[Q] HELP. HTC One X Stuck in bootloop. Almost all famous solutions tried out

So I wanted to go to Lollipop and I happened to flash the twrp recovery for new layout(as i was getting boot loop when flashing the rom with cwm recovery)
The things i tried until now.
1. Installed twrp and formatted it to get the new layout. Wiped everything, system, cache, data, dalvik cache
2. It was supporting MTP so i transferred the roms to the device being in recovery. Installed CM 12 + gapps for lollipop.
3. Rebooted to bootloader again. flashed boot.img, and did fastboot erase cache.
4. Rebooted again and stuck at CM boot logo.
I wiped the cache, dalvik cache(actually did a factory reset in the twrp recovery) and tried installing Resurrection Remix. Again flashed the relevant boot.img too. But the same result..
Did i destroy my phone?

can you enter in recovery ?
wipe dalik,chace,chace,data then go to,mount select system,chace,data,2gb extra data ,and disabel mtp
if your phone dot show up just leave it on select partions to mount ,unplug cable then plug it back,go to device manager btw and see will it show there

Yes I can enter recovery. But again I just cant get any lollipop ROM's working. I dont know whether i have to restore to kitkat(i really dont want too..
I dont get it.. Wipe dalvik cache, cache, data and then disable mtp and then enable mtp.. I mean at the end what does this do?
And in the meanwhile did you mean HTC Sync Manager for device manager. FYI I use a mac(if this helps to get into the problem). And i had flashed kitkat roms from the same without a hiccup but lollipop is failing

its hard to explain with recovery you can mount ur sdcard and put another room and install ,the easy way its to start from the begin and install clear CM12 and you will get out from bootloop that help me i was in bootloop like 3920489208420984920 times hahaha
anoopknayak
Have you solve the bootloop issue? I am having the same problem on my International One X
thanks
Probably both of you encountered the same problem as me.
If you are S-on, you have to flash rom and kernel separately. Also, if you try to revert any changes with twrp you have to flash kernel you were using during creation of backup, and then restore backup.
In other words: your current kernel is incompatible with rom.
Mwys
Yes i am S-ON. Can you tell me what the steps are to flash the kernel? I do not have a backup.
What is did was flash New Layout TWRP, did a complete wipe, then copied the ROM and G-Apps zips to the phone, installed them and then flashed boot.img.
Thanks for the help
Yup I also tried the same. but no luck. I tried to revert back to kitkat(by installing cwm, format the storage, sideloaded the ROM and gapps, flashed the boot.img) and still again in bootloop.
Sorry for the delay. I was a lot too busy with work.

Wiped Internal Storage; now phone reboots on loading ROMs

Hey guys,
So last night I accidentally wiped internal storage in TWRP. I guess that messed up my partitions or something, I don't know. Anyway, I can still access recovery, and I've tried to do a restore (one that I made back when I was on stock 4.4.2 I think) but after that it tries to boot, gets to "Android is upgrading... Optimizing app Y of X." and once that operation completes it shows the lockscreen for about a tenth of a second, and the phone reboots.
I'm stumped. Anyone know what can I do?
Sorry if this has been asked a hundred times. For some reason the search function in the forums isn't working for me. And I've been looking for a solution all morning.
EDIT: FYI when I tried the restore I did only System and Data and not Boot, because I was afraid that'd cause more problems.
Did you try restoring and performing a factory wipe before booting the newly-restored ROM?
It seems that Marshmallow based roms aren't working, but Lollipop ones will boot. Not sure why as I didn't have any problem with the same MM roms in the past.
More info:
MM roms wont flash in TWRP; after the failed attempt, TWRP says system cannot be mounted until I either wipe or install a 12.1 rom.
Tried to install a stock rom (4.4.2) and it failed in TWRP. Just says "Error Flashing"
Are you performing a full wipe (system, Dalvik, cache, data) before installing or restoring a ROM? Is the phone running the latest version of TWRP?

Yes to full wipe. TWRP is 2.8.7.0, so yeah I think it's the newest? Not 100% sure.
Wiping internal storage should not affect the partitions. I'm not sure that TWRP even has the ability to change partitions.
Yes, 2.8.7.0 is the latester version of TWRP.
If you are on the nj2 bootloader, try flashing this in TWRP: http://forum.xda-developers.com/galaxy-s3-att/general/rooted-ucufnj1-stock-rom-t2985006
Welp, seems to be all good now. Not sure if I really did anything to fix it or not. I tried to install a stock ROM but it wouldn't boot (stuck on Samsung logo) but after that my CM13 ROM installed properly again. The one CM13 ROM I have still wont install at all - maybe that file became corrupt or something? Not sure if that's even possible.
Either way I'm all fixed up. Thanks for all your help.
Cheers
Glad you got it sorted out. If you do figure out what you did to get it working, post your answer as it may help others that are in a similar situation.
