Phone unable to get past CM13 boot logo (with video) - LG Optimus L90

Basically, I had to do a battery pull on my LG D415, after the better pull, I booted up the device like I normally would. After starting the device, I am now experiencing an issue where I am unable to get past the CM13 boot logo, where it will continue the booting animation with the CM13 logo, and then the device will just shut down. Attached is a video of this happening.
Is this essentially the inevitable bootloop that is found in many Android devices? If so, how can I go about fixing the issue? I had a lot of stuff on the device and would prefer to not have to reflash anything, as I spent already hours setting up the device in the first place.

Usually a bootloop restarts your phone or doesn't pass the CM (in this case) logo.. I think u can classify as bootloop nevertheless.. u can try reflashing the same version of cm13 on top of that.. you maybe won't loose anything important but I don't know what you had done in your device.. it's just my opinion..

So if I were to flash CM13 (without wiping anything) I should be safe in terms of not wiping anything? Would I also need to flash GAPPS again?

I don't know.. again it's your decision.. but if your going to flash, try 1st without Gapps.. if they don't stay then flash Gapps.. btw I saw u want to download cm13.. that's a bummer because cyanogen is over.. they closed CyanogenMod OS. So no more cm's for anyone. Instead u have lineage OS that's made by CM team and we don't have official. It's the same with changed brand.. I don't know if you will succeed downloading a cm13 version but search here in L90 forums.. maybe you find a solution..

Oh yeah, I totally forgot that CyanogenMod closed down its OS. This is a huge bummer, as this essentially means I need to find a new ROM anyways...
Any suggestions? Anything super stable, and runs fast is what I was looking for. If not, I might just go back to the stock ROM and stay rooted or something.

Thanks for the advice, I'll go ahead and take a look at it! As long as it's stable, and good to use as a daily driver, it works for me.
Though, I am currently having an issue with booting into TWRP to flash the ROMs, as I keep trying the volume up + power button steps to get into recovery, but it's just sending me directly to the CM13 loading logo. And because I can't even get into CM13 because of the boot issue, I am not sure if I can connect the device to a computer... Any advice on how I can fix this issue?

Its power button and volume down.. I read that ur going to give your L90 To another person.. I think u should not flash nougat Roms yet.. they are still "beta ish" Roms.. Instead try this https://www.androidfilehost.com/?fid=673368273298925163
Its a unofficial build of lineage 13 made by @slimshadys and is basically cm13 last nightly made.. should be very stable.. doesn't bring root by default but just flash SuperSU 2.79 (last version I think) and will work ok

Haha silly me, yes volume down + power did the trick. I always get confused with that because it seems to be different for many devices. Yeah as I posted in my other thread, this phone is meant for a friend who uses it daily, it sounds like that lineage 13 is pretty much fit for the task? Would it receive updates in the future? I am always open for trying other ROMS of course, as long as they are 100% working and have no issues/

As it is now lineage 13 is the best option for stable.. But dont expect updates on 13.. Later you can use 14.1 but now it have some issues..

Oh okay, thanks! I'll go ahead and just do a fresh install since I forgot this phone has an SD card, so the majority of the data needed is already there. Thanks for your help! I'll keep looking at 14.1 and rest of the Nougat ROMs, and consider flashing it if they become stable soon.

So I installed lineage OS, but for some reason can't provide root access to apps? Attached a screenshot, not sure why it's not allowing me to select apps, and only showing ADB...
EDIT: No idea how, but the SIM card reader stopped working... I tried flashing another ROM just to see if it was lineage, but it wasn't. The phone is still under warranty, but I assume if I send it back it'd have to be unrooted... any idea how I can go about that?

Oh great, thanks! I used to have the old myTouch 4G, and unrooting that phone was such a pain, I nearly spent 6 full hours because of all the steps needed and it was so easy to mess up. This looks pretty straight forward. On the bright side, I now know once I get the phone back I can flash lineage OS and should be good to go.

Before you flash kdz maybe the problem was bootstack.. Dont really know if that was the problem because its supposed to work if you still have a KitKat bootstack installed but try changing that.. Just be carefull to choose the right one..

Some questions about root and roms

I was never into following what is going on with smartphones. So i have a few questions so that i dont feel lost.
So i want to root my phone. I have done it before, its pretty simple, i will just follow the guide. Are there any reported bricks coming out because of rooting moto g2 or is it relatively safe?
Then since i was going to do a hard reset for the root i thought about using another ROM. I dont generally know anything about mods. I only know the famous cyanogen mod. Is it working good with moto g2? Are there any problems? Is development ongoing? I think i saw a guide but i missed the link btw.
Now i generally dont care about my phone looking great with 3D stuff and gimmicks for showing. I want it to be as fast as it can be and ready to do as many things as it can. Thats why i am rooting it btw. So that i can do things that unrooted wont permit me and so that i can block adds for example in order to make it a bit faster and less power/data draining.
So is the CM mod okay with what i need?
And finally, since lollipop is coming out, should i wait for it to be available before i do anything in case that there would be a lollipop CM for moto g 2 or this would probably take too much time so i better do the hard reset now? Btw i am not sure if CM mod can be upgraded without hard reset in which case i am good to go.
P.S. I am not even sure if CM is really better than official. Any hints why it is better?
Thanks for your time.
U can easily root without brick.

No bricks reported from rooting only so far. It's a relatively safe procedure. CM12 is still in it's early days. Across all devices there are still various bugs. If you like to try lollipop there are two possibilities. Wait for ota (be sure to unroot and restore stock recovery. OTA won't install if you are rooted or have a custom recovery). Or you can try TitanPrimeROM (not the cm version). Its based on stock and runs quite nicely.
Thank you for the replies.
So i think i am going to just root the phone. But i wanna ask why is this thread locked? Is there any problems with this guide?

Damn i just rooted it with 2.7.1.1 cause i saw there were backs with the one i posted but couldnt find a more recent one.
I guess i will have to do it again... Thanks though!
And one final question, every time i want to change a rom it is like doing a hard reset right? There isnt anything like backup or something that will help me keep apps and data while changing roms.

You can try Titanium Backup.. It allows you to backup your apps and reload them in a new ROM..

[Q] Introductory help

Wanting to get rid of bloatware I didn't want in the first place and explore more on the Android mobile operating system I decided to make the jump towards a custom ROM and here I am. I have been impressed with my first flash of CyanogenMod 12 so far but unfortunately have run into a various amount of problem which I have tried to explore before coming here. The only problem I've sorted so far is the normal "install core Google apps without additiona bloatwarel"... But that was easy.
I have the following problems:
1. No LTE.
I'm on o2 PAYG and have entered what I think are the correct settings for use of the Internet, but unfortunately I still have no Internet capabilities beyond WiFi. When going on search for networks it will spend time before going "error while searching for networks".
2. Audio and video.
-Most noticeably on Snapchat, when I record a video the phone goes haywire and may spend 5 seconds vibrating before spending the remainder of its time being generally slow until I restart it.
-When I bring up the music playing app, I press to play a song and the audio doesn't work, nor is the song actually playing. The track bar may go to 0:01 with no sound before going back to 0:00. The device also lag once again, but not as bad as SnapChat instance. The system audio works fine as button response audio is fine and calling works fine with ringing and hearing the recipients voice.
I have gone through a couple of threads to try and find answers so far, but unsuccessful. Any help would be appreciated.
My current set-up is:
Phone: Sony Xperia SP
Android version: 5.0.2
ROM version:12-20150120-UNOFFICIAL-Ibhuashan (would be happy to change up ROM if advised so)
Kernal version: 3.4.0
I would be happy to supply additional information to help.
I'm hoping to get to know my phone and start contributing in some what possible way on the forum, but for now I just want to find my feet in this exciting new adventure
Many thanks for all help given.

Hi, I had a check and retraced my steps of unlocking and rooting before I installed CM12. The device is unlocked but is not rooted any more. The rooting method via towelroot no longer works for me and ends in constant rebooting.
Hope this helps!

Sorry for the late reply, I had only found the time to start this today.
What benefit do I gain from changing up my kernel? Is the ROM previously mentioned alongside the kernel update only available for devices running a particular kernel?
Many thanks for all help so far!

the benefit is like faux sound ...you can control your cpu and gpu and a lot of things ....last update of the ROM that i gave you is only working with costume kernel (t-kernel) so yes you have yo flash ROM then t-kernel and then reboot ....if want there are like cm12.1 ...it doesn't need a costume kernel ...just flash cm12.1 and reboot......so you can choose .....happy flashing
good luck :good:
Soft-bricked the device after I wiped,attempted to install the 12.1 ROM but failed due to it saying its not the right device, and then accidentally restarted not paying too much attention to the yes and no's of CWM. Sony logo starts up but nothing else at present. Trying volume{up, down} + USB but nothing at the moment vibration or light wise. Hopefully this is fixable, not too worried at this point in time unless I should be?
Currently following this thread for instructions. Unless you can advise me on better or even if you have to tell me its straight up gone...

don't be afraid ...you tried to flash cm12.1 that mean you are UBL....flash t-kernel v2.2 twrp via fastboot mode and you will gain recovery to flash again the cm12.1
Fortunately kept calm and have gotten back to having an OS present. I've currently status quo'd back to CM12.
I have PhilZ, can I just use the PhilZ instructions for t-kernal?

yes of course ! .....if you want my opinion> wait until the AICP\ RR \ROMs to be up to date ...they will update it today or tmw(very soon)
Installed t-kernel and AICP. It boots and then gets to optimizing apps. Once it completes the 82 optimizations it goes "starting apps" it reboots... should I faactory reset & wipe the caches and reinstall? Almost there haha.

do as following
,,,,please do a full wipe and then flash AICP and flash t-kernel v3.0 and then reboot
Wiped data&caches, flashed AICP then flashed 3.0 t-kernel. It reaches starting apps and completely freezes instead of rebooting now. waited 15 mins hoping it was really slow but it's frozen. I then wiped and tried to reflash but that particular recovery setting doesn't like the checksum of the t-kernal so doesn't allow installing, so i flashed back to CM11 and reflashed AICP & t-kernel, completely following the steps given.. but once again freezes at starting apps.
Any more ideas? Thank you for all effort given so far!

Once again... wiped entire user + cache and first installed 12.1, then gapps core and finally t-kernel 3.0. It gets to starting apps and freezes. I'm able to flash CM11 or CM12, but that would mean the original problems encountered which makes my phone half -useless. I've tried to boot into safe mode, not knowing if you can do that with an un-optimized android.
It's all getting a little bit weird now. Something is going wrong somewhere, but I don't know.

wiped and attempted to reflash and the installation failed. Next I connected it to my pc and went into fastboot mode and wiped data/cache/system and flashed 12.1. It boots (sign of t-kernal is gone) but has so fa yet to do anything else, the current screen is blank b ut it is on.
I hope this information was useful to you. It seems to me to more up the current ROMs I go, the more they seem broken.

this is far from weird ....the last hope for problems like these ...to start from scratch ....to flash ftf ROM via flashtool and re install recovery then twrp then reflash the ROM (5.1) ..only few users had this problem and solved it with flashing ftf ....sorry man for that but i think you have to do it or stick with cm11 or something
good luck ...if you need any further help i'll help you :good:
---------- Post added at 10:04 PM ---------- Previous post was at 09:52 PM ----------
you use twrp last version right ?....boot into any ROM you can go to ...install rashr app and flash via rashr this twrp recovery and from that recovery flash cm12,1
i'm sorry i have to go to sleep now ...but first try to flash twrp ....etc...if that didn't help flash ftf ....

help with no data on any ROM coming back from M from maybe?

Hey guys, I am having some problems going from JDX down to a 5.1 ROM. I cannot get data on any of the ROMS I am trying.
I have tried to download a few radios seperate and flash them at the start, or after the fact and still nothing. I also manually went to the apn to set it up but the correct one is already there and that didn't work.
Is there something I need to flash to make it work correctly? I'm stumped!

Did you check and make sure the bootloader was configured correctly? I don't know if it even changes it, I will see what mine says. If you have to downdrage it, you will have to search further, I don't know how to do that on this particular phone

Downgrading is a Hassle
If you do decide to try the Android M beta release, you’ll have to completely erase your entire device and start over from a fresh install of Android. Users will need to backup apps and pictures, transfer all their data, re-download everything and set of the device the way they’d like. Then, if you decide you want to go back to Android 5 Lollipop, users will need to erase the device and do this all over again. It can be quite the hassle, time consuming, and frustrating for those new to Android, or aren’t used to doing this often.
Here is a youtube vid on how to downgrahttps://www.youtube.com/watch?v=TazsmCuA5Cwde
BL moto-apg8084-71.08 (sha-32b8854, then the date it was made
baseband d4.0-9625-02.95
product variant shamu xt1103 32gb p3a0
cpu apq8084 esi.1
That's what mine says, and your issue does sound like the BL got changed
Sorry I'm not more help, but that's what comes to mind rightaway
wow thank you do much for replying. That is what I thought too. I had 0 problems before with any ROM then I decided to try the JDX M preview ROM and since then going back hasn't worked.
I tried to download several bootloaders and radios and flashing them and using the toolkit to flash them. No luck I will watch that video and read that post and see if it helps me any.
Again, thank you!
so I downloaded it his way and flashed it his way and I still get no data.
gah!

You flashed the stock RUU? right? you should have gone to a google page that had the stock roms in them, it had links as well on the YT link I gave you, try again, I watched the vid and the maker was talking pretty fast, if you still have issues DL teamviewer to your computer and I will get on your puter and help ya out
lol, downgrading the bootloader will do nothing. im on m, with the m bootloader, and have hone to 5.1.1 a few times. always keeping my m bootliader.
if your apn is 100% correct, id just boot up, and eventually youll catch the signal, as long as its not disabled, or data isnt disabled.
of course, your sim card cohld have gone bad. they do die every now and then.

Hi Hi sorry for the delayted response.
Basically for whatever reason no CM ROMS would work at all. I tried some AOSP ones and they are completely fine and have no problems with them.
I Downloaded ROM Manager and will give a look into other CM ROMs in a little while to see if it works.
Thanks so much for all the help!

How do you like M? I was thinking about giving it a twirl, decided to wait until the bugs were gone, and it's more refined

Help flashing CM

I screwed up somehow. Maybe things changed since I last messed around with Android phones. I went into twrp and did a factory reset then installed latest nightly and these gapps ( https://github.com/cgapps/vendor_google/tree/builds/arm > gapps-5.1-arm-2015-07-17-13-29.zip), were they the right gapps? . Now phone won't boot or go into recovery mode so can't go back to my stock nandroid. I'll try going back to stock using wugys toolkit :/
Edit: I used the toolkit to flash stock + unroot option without wiping data but it finished too fast somehow and the options in bootloader were fixed. I booted up phone and now CM booting up. What did I do wrong and how did I fix it? I'm really confused and would appreciate some help.

my guess would be the gapps, mainly because i have never heard of the one you used.
perhaps, try a more notable one, like tk, slim, or banks.

I'll try that if my current setup fails me but why would gapps mess up the recovery? The buttons in bootloader kinda changed to just small text as well and the text under it which had the device details changed but I didn't make note of the changes.
I got the gapps link from the cm page. I guess it might be outdated but that's kind of their fault for not updating in their OP.

i cant explain it sorry.
gapps is usually the weak link then there are issues.

[Question] S6 Flat SM-G920T 6.0.1 Rooting

Hello Everyone!
Quick (stupid) question. How would one root the Samsung Galaxy S6 (Flat, T-Mobile Variant) running Android 6.0.1 (Stock)? Last night (As of this post) I've tried installing TWRP but ended in a bootloop at the Samsung logo, and (Thankfully) Smart Switch saved my ass. At this point, tripping KNOX isn't of my concern, as my phone's warranty has expired. Attached is my phone's Model, Build, etc.
Any help is appreciated.
-Matt
Use CF-Auto-Root.

Looking through all the builds, I don't see my build number. The closest one to mine (which is MMB29K.G920TUVU4EPF1), is MMB29K.G920TUVU3EPD1. Now, I would use this, but I don't want a 600$ brick, so unless it's compatible with my build, I'm gonna have to wait.

Ah, yeah, looks like you're running the latest update and it seems to early to tell if CF-Auto-Root will even work on it (I don't think anyone has tried yet).
Anyways, here's all the information you'll need: http://forum.xda-developers.com/showpost.php?p=67623487&postcount=7
Rest assured that you can't brick anything as long as you have access to download mode to reflash stock firmware.

Thanks for the reply. Hmm...last time I flashed TWRP on my phone, It got stuck on the "Samsung Galaxy" logo, stayed there no matter what, thankfully I was able to use "Emergency Firmware Reset." I've been snooping around forms, and some people state to, "UNCHECK AUTO REBOOT, when finished installing, reboot manually." Of course, I'm hesitant to try that, after all Smart Switch only backs up photos, videos, apps, etc, but not the actual Android operating system.
I'm gonna do a back up of what I can and try EncryptedCurse's suggestion. Wish me luck!

Did as instructed, still didn't work, freezes and shuts down at the Samsung Logo. Doing a Emergency Device Initialization now, and then restoring my stuff. Thanks anyway, I knew I shouldn't have updated to 6.0... :sigh:
So im guessing theres no way to root it yet huh?

From what I've tried, no. I had a feeling this would happen as soon as I upgraded.
On a side note, is anyone developing a kernel for build MMB29K.G920TUVU4EPF1? Twisted Six's kernel only goes up to EPD1...
What if you just downgrade back to lolipop ??

The latest update expressly prevents downgrading.
