Root Installing CM11/CM12/PAC on the L90 D415

hey i went on flashify and i made the recovery but the only options in the flash section are "Boot Image"
"recovery Image" and "Zip File" so how do i install the rom becuase there is no install rom option
Once you install the recovery. You need to reboot into recovery with flashify then there will be an install option
 
Finnaly got it all working, I installed cyanogen mod 12. I'm thinking of trying out the Pac Rom, can someone explain the differences/benifits, and I have noticed my battery life is WAY better.... But I don't know if thats just because I had a lot of stuff running on the stock rom all the time...
 
Sweet, I didn't realize there was an updated version for cyanogen mod 12, I'll have to try it out
Yeah, I am going to update the thread soon. I'm just a very busy person.

Anyways, I like PAC ROM because it has a lot of options. If you like to tweak settings, PAC is your way to go. As of now though, PAC ROM for the L90 has not been updated to Lollipop so you would be on KitKat
 
Cool, Let us know once the forms updated, I tried the Pac Rom but it didn't bring near the battery life and performance improvements the lollipop based cm12 did

Thread updated, Links for CM12.1 and the appropriate gapps are now open. Please let me know if you have any problems.

Also, soon enough there will be PAC ROM 5.1 Lollipop.

Let me know if you need anything. :)
 
Downgrade your firmware merely to Root easily?

I dunno ... I love Towelroot, but that's alotta fuss.

Isn't there an old-fashioned root procedure?

If you look at the downgrade to root thread, I posted a link a while back that should work but no one tried. Use that

Fantastic! Everything has been working well EXCEPT for a few issues I've been having with CM12.1.
First of all, the the most major thing is I can't record video at all. I've downloaded all different types of camera apps, and all of them fail to record. Also, ever sense I updated to CM12.1 my computer wouldn't recognize my device when I type "adb devices" in Command Prompt. I've searched a billion different methods for fixing this issue, and none of them have worked for me so I had to resort to adb over network. A few minor issues that are just annoying and not really too much of an issue is that my data connection and WiFi connection don't work at all until I do a soft reboot and my app drawer open animation is really choppy and gross every time I open it, and I don't know why that is an issue at all because it was working perfectly fine and smooth when I first updated to CM12.1. And one more thing is that I only get 3g connection instead of 4g connection. So I'm not sure if any of these issues are normal and everyone is having them with this specific CM12.1 version or it's just my own issues... (also, I thought it might be important for you to know that I am completely new to pretty much all of this)
 
This ROM Is great and I appluade the the creator for taking the time to set this up, it is confirmed working on my lg optimus l90, but beware it is not rooted, I didnt realize and have made a terrible mistake lol.... I cant use titanium backup to install all my files so yea..... But Cyanogen does give you a chance to reload all your files to the phone so
 
Looking forward to your Root Guide, Dev ...

Fwiw, I overlooked an important point: My D415 is 10e , not 12 ..... specifically: "Software Version D41510e" ... I've gathered the root procedures differ for this older version.

And it's true: I have no "Developer Options" ... I've looked throughout Settings, and nothing. Further, the terms 'developer' and 'debugging' are not mentioned anywhere in the L90's 122 page Owner's Manual..

So, I'm thinking Debugging is blocked, that's my problem ... that's why PurpleDrake stalled 3 or 4 times:

Thanks for your help.

Go into settings, then about phone, then tap build number many times quickly. That will open up developer settings
 
I got some issues, I follow the guide to the very end, but when I install rom and gapps and I reboot ... the device enter in a reboot loop.
What I see is the cyano logo, after a popup like Installing google apps and then the device reboot itself.
Any advice?
Can I install somehow also a stock rom to retry the downgrade?

Thanks
 
I'm Semi-bricked - I can get into TWRP recovery with the magic button presses after doing Factory Reset, but I can't install PAC ROM because the /system partition won't mount . The TWRP Mount screen will let me check the box to mount it, but then when I attempt to install PAC from the SD card, I get some quick screen then back to the main TWRP menu.

I can't get into fastboot mode, either.

I rooted the phone with Towelroot befor starting all this, and I also responded Yes when TWRP askedme if I wanted to install SuperSU.

How can I get the system partition to mount ? If I can't do that, I'm screwed ...

Does this require a unlocked bootloader?
No. This phones bootloader is to be loki'fied it's done in the recovery flashing process for us with flashify. I hard bricked mine got a different phone. Be careful do your research and verify this information please.

If you're using official T-Mobile CM you need the patch zip too. please reflash recovery from faatboot by turning phone on in recovery and issuing ADB command ADB reboot fastboot from a PC, reflash correct TWRP image via fastboot then reboot to TWRP via ADB reboot recovery. Wipe system data cache dalvik cache then flash ROM, then Patch, then GAPPS.reboot to bootloop, turn phone off then factory reset from recovery. Factory reset fixed the initial bootloop in recovery for me coming from stock. Something from stock sticks in the flash factory reset corrects it.
