For LG L90 D415, upgrading to Marshmallow 6.0 and doing stupid stuff along the way!
I'm new to flashing and ROMs, but I had to piece this together over eight hours last night, so I wanted to share the results in case anyone else ends up in the same situation. I'll include step-by-steps and download links below.
What Happened:
Decided to leave T-Mobile and use Hangouts over wifi for free phone service. (Which totally works, btw - I pay $15 a month for high speed wifi at home, and wifi is everywhere now, so there are just small travel gaps when I'm not reachable. You can use any wifi capable phone or tablet to do this without any kind of paid phone service.)
Got tired of T-Mobile bloatware and decided to break phone free by converting from Android 5.02 to Marshmallow.
Rooted phone with LG OneClickRoot.
Used Flashify, TWRP, CM13 and gapps to convert.
Internal storage was nearly full after conversion, so newbishly decided to delete CM13 and gapps zips from storage, deleted TWRP and Flashify folders, *and backups, doh* and then-
Tried activating Encrypt Phone function, which failed, locking me in a bootloop from LG logo to CM face to Decryption Unsuccessful - Reset Phone screens.
Being new to all this, I Googled solutions like crazy. I watched YouTube videos and tried anything I could find. If you're a newbie too and none of these work for you, now you know you're not alone.
What Didn't Work:
Powering off, then restarting while holding down Power and Volume Down. This sent it into TWRP, which would process something for a few seconds that I had no control over, and inevitably dumped me back into the bootloop.
Powering off, then restarting while holding Power, Volume Down and Volume Up. Apparently that isn't a function of this kind of phone.
Updating Drivers - Device Manager wouldn't let me install LG or universal ADB drivers. When the phone showed up at all, it registered as "MTP Device" and declared it had the correct drivers. Hand-picking drivers with Have Disk didn't work either.
All other attempts to get back into TWRP so I could wipe and reinstall.
Downloading Minimal ADB and Fastboot - "adb devices" in the command prompt couldn't find my phone.
Downloading Odin in the vain hope it would somehow see my device and magically make everything better.
Smashing phone repeatedly against forehead.
What Finally DID Work:
I found a page suggesting I power off, then immediately hold down Volume UP and Power, and plugged my phone by USB into my computer at the same time. This finally broke the cycle into a Firmware Upgrade screen.
This screen will tell you not to unplug the phone until the process is complete. Its progress bar will rest at 0% forever while you do other stuff to fix it.
While it waited, I downloaded the entire LG L90 firmware .KDZ file, and a program called LG Flash Tool 2014.
I extracted LG Flash Tool 2014, then extracted the .KDZ file into its folder.
I ran LG Flash Tool 2014, set Select Type to 3GQCT, set PhoneMode to EMERGENCY, selected my KDZ file and clicked Normal Flash.
It then asks you for country and language - select Different Country and English.
The first time it ran, all the text was ?????????, and the program errored out and closed. My phone *did* process the FirmWare Upgrade even after LG Flash Tool 2014 errored out, so I waited until it reached 100%.
I ran it again with the same settings, and this time the text was English. The Firmware Upgrade on my phone processed to 100% again. I think LG Flash Tool 2014 still errored out, but it looked successful.
On reboot, it took me to LG logo, CM face, and then a white "draw a pattern to unlock" screen, which is what I'd set as my security before I screwed everything up. However, drawing the pattern did nothing, it just stayed locked.
On re-reboot, I held Volume Down and Power, and this time it went to the Factory Reset screen. I selected Yes, and it loaded into TWRP again. PHEW.
At this point, I think my computer could see my phone again, so I plugged it in with USB and copied the CM13 and gapps zips back where they'd been.
In TWRP, I ran Wipe, then Installed CM, then gapps.
I selected Reboot System, and voila, booted properly into Marshmallow.
Unfortunately, Marshmallow was working, but Google Play was freaking out - I kept getting multiple "Unfortunately, Google has stopped working" messages every ten seconds. But I found downloading a different version of gapps, and using TWRP to wipe the system again, back it up properly, and reinstall fresh copies of CM13 and the new gapps fixed the problem.
Also, the CM13 zip I installed is apparently not the most current, so my phone told me there was a Nightly update available. I did a fresh wipe and install with that new one in TWRP. I don't know how to link to it, but your phone should tell you automatically that you can download it once Marshmallow is running.
Links to the programs I used to fix my phone and properly install Marshmallow:
LG OneClickRoot: https://drive.google.com/open?id=0BzczCljwgNnuSDZoSXBNTUptcDA&authuser=0
Flashify (you can download and install TWRP straight through this program): https://play.google.com/store/apps/details?id=com.cgollner.flashify&hl=en
CM13 (The original I used before my phone told me I could update): http://quarx2k.ru/index2.php?m&dir=lg_l90
gapps (The one that fixed the Google problem): https://www.androidfilehost.com/?fid=24052804347835438
LG Flash Tool 2014: http://lgflashtool.com/download/
LG Drivers (straight from official LG site): http://tool.lime.gdms.lge.com/dn/downloader.dev?fileKey=UW00120120425
LG D415 Firmware KDZ (To use with LG Flash Tool 2014): https://www.androidfilehost.com/?fid=24052804347759872
Theoretically, I think if you follow the steps here to root:
http://forum.xda-developers.com/lg-l90/general/root-lg-optimus-l90-44-2-5-0-2-android-t3110257
And here to install Marshmallow:
http://www.droidviews.com/install-android-6-0-marshmallow-for-lg-l90-with-cm-13/
But use the Benzo gapps from the link above, it should install properly the first time with no Google problems.
I hope this helps, and good luck to other newbs out there!

Hey all,
I have a problem with my lg p990. At this time, I am trying to figure it out whether is a software or hardware problem. I have searched each and every forum to over come this problem but went in vain.
problem:
1) lg p990 shows lg logo and goes blank.
2) when vol down and power is pressed the phone goes to s/w upgrade screen.
steps I tried:
1) I have used smart flash to flash my phone to stock ROM.
a) downloaded the stock ROM and flashed with smart flash. The smart flash says process complete successfully and the phone restarts and shows lg logo and goes blank.
b) I tried to flash different stock ROM with the smart flash but same result.
2) I tried using the lg update tool (offline procedure since lg blocked it).
The lg update tool successfully completes the update procedure and tells
the phone will restart. The phone goes to restart and the phone shows lg logo and goes blank again.
3) Last but not least, I tried to download the custom ROM.
a) I downloaded the ClockWorkMod recovery by using nvflash
b) after successfully download recovery image, wipe cache/factory reset/wipe cache partition/wipe dalvik cache.
c) copied ROM in the root of the internal sdcard (connect the phone-->mount it-->copied the ROM and Kernel--> installed the package--> says installation complete-->reboot phone--> the phone does not get pass through lg logo and stays blank. I have waited for 30 minutes but no luck.
I don't know what else to do. After I tried all the steps, the phone just powers on and shows the lg logo and goes blank but the menu,home,search button still lights up. I also resetted the phone but still same problem persists....
Any help would be greatly appreciated otherwise I have a paper weight worth $350.00
I had the same problem as you face here.
I tried everything NV-flash, smartflash, you name it, no luck. Then I did a emergency repair in the LG updater.
Start the Updater, select "emergency repair", make sure drivers are installed.
Battery out, press Volume Down and connect.
Enter IMEI and S/N and repair program starts.
I had to do it twice, before it finished. I maybe had a bad USB connection or cable, but after "S/W update" showed up in screen on second attempt, I reinserted battery and it went very smooth.
Let it boot.
And then root with NV-flash and you are back in business with normal GB partition table.
I can recommend Tonyp's CWM 6.0.1.5 touch for NV-flash, when you have finished rooting.
It took me 45 minutes, with a not too good internet connection.
PS.: I did not try this one: http://forum.xda-developers.com/show....php?t=1715272
but since I could not call up NV-flash, I did not want to spend even more time trying.

Exact same issue here...
You found a solution yet ?
My lg stuck on logo.I use this http://www.modaco.com/topic/335474-25-mar-nvflash-stock-rom-release-v10b-dated-1300166062-15032011/
and i use this for clean stock http://forum.xda-developers.com/showthread.php?t=1264289.
I have spent about 10 hours sitting here, with over 200 tab open trying to find a solution to my problems but I could not find one. My last option is to post here and hope someone can help me out.
I recently bought the tf701t which came with Android 4.2.2. Everything worked fine. A few days ago, I got pushed an update to android 4.3 but it was .1.7 not .1.18 (the newest apparently). With that update, my problems came. When I light up the device by pressing the power button, the lock screen was unresponsive. I pressed my pin numbers in but there was no response and it was as if the touchscreen was broken. However, the home and back button were all working fine. I had to randomly keep pressing until it finally started becoming responsive. When I got in, the quick management window (the one you get by swiping down), kept popping up the moment i press the screen. Because of this, I couldnt do anything. I couldn't even turn off the tablet as the power off option was unable to be pressed by me (When i did press, the window came up again).
After a while, i managed to get around this by again randomly pressing stuff. I got really frustrated and decided maybe if I install a custom rom, this problem might be fixed.
I read around a bit and found that the CROMix rom required firmware 1.18, which I did not have. Because of this, i decided to try install 1.18. First i used the asus unlock tool. Next I tried booting into recovery but here I met my problem. I have guides telling me to first boot using power button + volume down key. This worked. It then told me to choose the RCK option and press the volume up key. This however, did not work. When I selected the RCK option, the android figure appeared lying down with a red triangle and exclamation mark over it.
Unsure of what to do in this situation, i read one of the guides on this forum which said simply place the 1.18 zip file (yes i unziped the zip file from the file i downloaded), in the root folder then reboot and it would automatically update. This didnt happen.
I then tried using the adb thing but it said no devices were connected even when my tf701t was connected to the PC. I guessed that I needed to be in the recovery mode that I could not get into, before it would work.
I then read around and they said I had to first get Rom manager + the CMR recovery thing but Rom Manager said it needed root access. In order to get root access, I needed to get into the recovery mode yet again.
So now I am stuck. Whenever I try the RCK option, the error pops up and I can't get any further.
WIll someone please help me? I have no idea what to do anymore except throw the tablet out.

Did you try to put the update on the external sd card? Not sure if that would make a difference but i remember i used to put it there...
You could also flash a custom recovery and flash the update that way. You can find more info in this thread:
http://forum.xda-developers.com/showthread.php?t=2636093
You should safely be able to update your factory firmware first by putting it at /sdcard location.. Then just reboot. It automatic. I Thought there was also an update available in settings after that. Don't unlock til you are at 4.3.
To unlock with Asus unlock tool make sure Google 2 Step verification is disabled.
Then I used fastboot to flash CWM recovery from a computer. I think you flash with fastboot from the newly unlocked bootloader. Power + Vol DOWN.
After you have flash recovery then you can enter it. No scary man lying down.

I forgot to mention one thing at the start. I don't actually have on hand a external microSD card. Which I think might be why placing the zip file in the root of the internal storage did not work.
Should it work? Is there any way to get around it? I've been trying to use sideload with cwm (finally got cwm working), but it comes up with "failed to write data protocol fault no status"
EDIT: Through cwm, I chose "choose zip from /sdcard" then select the "0" file directory then i found my zip at the location. I selected it and confirmed install. However, it then comes up with "Error in data/media/0/(name of update here).zip status 6"
Thanks for the help so far but anyone have an idea about this?
Not sure. After googling I see this

You can put the zips anywhere when your recovery is installed.
Okay so I finally managed to get the custom rom installed and working. However, this did not fix my problem with the touchscreen. I think it is because it only changed the firmware but not the android version (still 4.3).
Is there any place I could find android 4.2.2 rom? This was the one the tablet was on before the update that screwed everything up. If I could downgrade to that version, it may work again.
Thanks
I gave up and just put on the android 4.3 ota from droidbasement. Now the tablet randomly restarts and is stick in reboot loop. It wont even allow me to boot into cwm recovery to delete the cache. But i accept that I now have a $600 piece of **** on my hands. Going to bed. Night.
Ya i dont like the whole void your warranty for "using it" idea. If it responds to fastboot you might be ok.
You should be able to download a 4.2.2 rom from Asus' website (.47 was the last build for 4.2.2). You can use fastboot to install it.

I tried that before but it stated "update aborted" immediately after i pressed confirm, in CWM.
But all that is in the past now. I am pretty sure that the tablet is hard bricked since it no longer even opens bootloader. I accidentally pressed the wipe data option and I read that irreversibly damages the tablet. When I hold pwr+vl down, nothing happens anymore, it keeps on its reboot loop.
I am having a hard time recovering from my curiosity with my XT1060, Developer's Edition (unlocked bootloader and all)
I had factory 5.1 ROM, xposed and all tweaked. But it's been months, phone's getting slow, and I'm itchy for MM...
So last night, I made a TWRP/nandroid backup onto my USB-OTG stuck, and then, installed Resurrection-Remix-M.
Works fine, until I tried to make a call. I can't hang up. After 30 seconds, the phone rebooted.
I had another guy call me. The phone rings, but the screen is blank. I cannot pick up the call. WTF? I tried turning screen back on, screen's blank. After a couple attempts to swipe blindly, power button, the phone rebooted.
At this point, I'm like WTF, that's enough. So I tried to plug in the USB-OTG and tried to restore.
TWRP does NOT see my backup. At this point, I realized that perhaps TWRP can't see the item due to MM's security structure.
So I engaged the RR's CM explorer and copy the Nandroid backup onto the built-in 32 GB . THere should be enough room.
I looked back X minutes later, the phone had rebooted itself (?!!) and it's stuck at the bootloader logo (I had replaced it with generic "White Google" logo)
I cursed a bit more, did the VOL-DOWN / POWER to bring up the Fastboot menu, and boot into recovery. I got the Team Win logo, then nothing. I waited 5 minutes. It's stuck too.
At this time, I'm cursing a blue streak. My phone has been dead for HOURS now, no end in sight.
I went back into Fastboot, did Factory (which I assume is "Factory Reset?") no effect. Still freezes both normal boot and recovery boot.
I boot back into Fastboot mode, I already have Minimal ADB and Fastboot loaded on PC, so I use that to flash the a new recovery.IMG (downloaded fresh off TWRP.ME for ghost) and rebooted. STILL FROZEN at TWRP. WTF?!?!?!
(FWIW, Ghost TWRP is still 2.8.7.0, while TWRP main is already at 3.0.2)
At this time I'm at a loss as on what to do.... I tried extracting one of the factory ROM's boot.img and flashed that via fastboot, nothing.
I just RSDLite the 292-ghost_verizon_51.... ROM onto the phone (with servicefile option). It rebooted to the bootloader warning, so flash did work, but it doesn't seem continue to boot either, but I guess I was supposed to have waited like 10 minutes just to get past the bootloader? I flashed the TWRP on there. Still waiting for TWRP to load. After a couple minutes, I decided it wasn't working.
I'm now using RSDLite with the Flashfile option (wipe out all the data). Wonder if this will do it?
EDIT: Now I'm past the bootloader logo and now it's kinda stuck on the Verizon logo, but I guess that's to be expected. Still charging... and waiting.
EDIT2: Verizon logo took about 5 minutes to boot into setup. I just hit skip / skip / skip until I got to launcher. Shut down, reboot into fastboot, flashed recovery again, and booted TWRP recovery successfully this time. (sigh)
Lessons to take away from this diversion that took HOURS away from my life... For no appreciable gain.
* Keep a flashable nandroid backup on the phone. I know it takes up GB's of space. But you'll be thanking yourself (and maybe me) when there's a problem and you need to recover, especially if you're into MM or N.
* And keep that nandroid backup UPDATED! (nightly, if possible)
* ALWAYS keep a copy of the stock ROM on your regular PC, and keep Minimal ADB/Fastboot (or whichever flavor recommended for your device) and Gapps loaded. Do update every once in a while.
* ALWAYS refer to XDA
Recently I tried out the Nougat preview on my EVA-L09C636. It was ok but seeing as there was a problem with fonts and I'd lost root access, I began thinking about going back to MM.
To prepare for downgrade I tried using srktool to bring TWRP back (and I think this is my big mistake as srktool uses a TWRP made for MM, not N, is that right?). After I tried to restore TWRP I noticed "not recognised" errors when I connected my phone to PC again.
System recovery using hajuuk's Firmware Updater and HiSuite looked like it would complete but near the end of the process (the restoring system part) HiSuite aborted itself saying my device wasn't supported. This has left my P9 is in an unusable state where the only thing I can access is fastboot. Also I can't turn off my phone - holding down power simply makes it reboot then get stuck at the "Your device ... can't be trusted / Your device is booting now" screen.
Reading around a bit I attempted to unbrick it without any luck:
1. downloaded EVA-L09C636B152 update.zip from http://forum.xda-developers.com/p9/development/rom-stock-rom-eva-l19c636b168-t3419586 and installed Snoop05's 15 seconds ADB Installer.
2. extracted images from update.zip using Huawei Update Extractor and did
Code:
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash cust cust.img
then tried rebooting holding volume up + power several times (but never got past untrusted device boot screen).
3. extracted contents of update.zip to folder 'dload' on a blank sd card, trying to force update several times by rebooting and holding down power + volume up + volume down (still never get past the screen saying my device is booting).
At this point I'd be happy to get anything happening on my phone - Marshmallow, Nougat or even some other ROM so I can use my device again.
Any ideas? I'm on EVA-L09 C636.

Hi! I'm not sure how to wipe data, cache or dalvik, because when I upgraded to Nougat this apparently removed TWRP.
Also I'm wondering if trying to use srktool to reinstall TWRP for 6.0 might have corrupted my 7.0 phone?
Is there any way to wipe data, cache, and/or dalvik now? Or are there other things I could try to unbrick?
Although my phone was in a pretty bizarre state - it would get hot and sit on the booting now screen until battery died - I was able to use DC Phoenix to make it boot up again. At that point it had no themes and only KitKat-esque icons. A reset and upgrade later icons and themes work and I'm back on stock Marshmallow. Here's an outline:
1. Google "Huawei Bricked phone repair guide with DC Phoenix", go to the first result and look at the instructions (I can't post URLs yet).
I used Method 1. But note! The newer versions of DC Phoenix are missing a feature that the instructions make clear you have to use. To get the original version used in their guide, you have to download the latest version of DC Phoenix, open it on your PC, then click "Enter Support Area" which logs you in to a download section. Find "DC Unlocker Softwares", "DC_Phoenix", then download DC_Phoenix_v14.rar and run that instead. Whether it's Method 1 or 2 make sure you complete it - i.e. the fastboot flash step AND a step they call "flashing in upgrade mode."
(Also note that for DC Phoenix you want to feed it the oldest version of firmware available for your phone, in my case b152. This is because themes and icons won't be fixed until it receives the next version of firmware as an update.)
2. Once I did the fastboot and upgrade flash, I did a system reset from the Settings app trying to get themes and current icons again. (This didn't work but doesn't do any harm or might have helped somehow further down the line).
3. I used hajuuk's Firmware Updater and HiSuite to upgrade to the next version of firmware available (in my case b168).
3. All fine and your phone is back to stock - icons look nice again and local themes are back. To get the original icons layout, go to Recents, hold down on the Trash Icon, show system apps, and Clear Data for Huawei Home.

Thanks for sharing! You saved me!
After months of deliberation I finally decided to root my Note 9. It was the first time I've ever tried rooting and it seems to have gone horribly wrong. To root the phone, I followed the guide in the video titled 'How to Root Galaxy Note 9! [EASIEST METHOD]' on youtube which has an instruction link in the description. As a new user here, the forum doesn't allow me to post links yet, so please just type the title on youtube and it'll come up as the first result.
What I did was:
- unlocking bootloader
- Flash AP file with TWRP version 3.4.0
- Wipe data
- Since I was worried about using a software from an unknown source, I then flashed the official magisk v20.4 instead of the 'N9-S9_root_for_oem_issue_devices_v3' file recommended in the video.
After doing so, the note 9 restarted and showed the error message "Verification Failed, Unable to restart your device. The Integrity verification has failed. You need to reset your device to factory default settings. This will erase all your data.". I allowed the phone to reset.
Following this, the phone restarted and showed exactly the same message of 'verification failed' and no amount of going through the rebooting process resolved the issue. I googled the issue and was advised to flash the phone with Odin by going into download mode. I then tried to go into download mode, but the phone will simply not go into it and tries to restart the normal way. I also tried to connect to my laptop to see if I can flash with odin but the phone was not recognised at all by the computer.
I then tried to reboot using the twrp key combo and this worked. I then decided to try flashing with the 'N9-S9_root_for_oem_issue_devices_v3' file in the tutorial. Yet, this led to the same issue as with the official magisk file.
Looking at some rooting tutorials, I see that some of them recommend flashing CSC, AP, BL and CP instead of just the AP in the tutorial I followed. I then thought that perhaps the issue is I need to install a ROM on the device. I therefore tried to load the lineage 17.1 ROM in the micro SD card and installed it (top left option on twrp 'install') as well as the magisk and disable_dm_verify_forceencrypt zip files.
In hindsight, this was a stupid move from me - I did so I was in full panic mode at that point and desperate for a solution.
After doing so, the phone rebooted and showed a booting animation of a single blue curved line stuck with a circle rolling from right to left on it.
I left it for a while, hoping that it meant the new ROM was booting. 30 min later it was still stuck on the animation!
I then tried to reboot the phone. Pressing power button did nothing. I then tried different combinations and eventually power + volume up + bixby allowed it to restart in TWRP mode.
As of now, the phone is still in TWRP mode. The phone is still not recognised by my laptop and will not enter download mode if I press volume down + bixby when restarting.
I am fully aware that I've screwed up the rooting process and feel awful about it. It was the first time I've ever tried rooting and I really hope it is only a 'soft brick' and that my phone can be saved. I would really appreciate if anyone here could advise what I can do to complete the root process correctly from here?
Many thanks,
Sam
Is there a "download" or "bootloader" option when you press the reboot button in TWRP? My Note9 is on stock, so I'm not 100% certain myself. However if there is, that should take you to Samsung's download screen. This way you can send yourself back to stock if you give up on rooting your device.
BTW, I do recommend following a note9 rooting guide on XDA (it's not too hard to find) over a youtube video, since YouTube videos can often be out of date or a little sketchy.
