Hello there..!!
I just got a XT1521, as a secondary device. Its currently on stock Android 6.0 with baseband M8916_2020629.41.03.21.51R SURNIA_EMEA_DSDS_CUST
I want to make it just like the Pixel. I do know where to get the required files, and don't need any help regarding that.
All I wanna know is :-
1. What's the procedure to unlock bootloader on this device? Unlocked successfully
2. Which recovery should I use? I used Squid2's TWRP v3.0.2-r1
3. Which ROM can be used as a daily driver? (need 7.0+ to get Google Assistant working). My preferences are good battery life (if not extreme) but the performance should be smooth without any lags, unlike the stock M. Also, wifi, OTG support and other features should be working properly.
Flash Seraph08's CM14.1, its totally smooth with wifi, otg and everything working. Also, I've managed to install Google Assistant successfully
4. What's this adoptable storage thing that people are having problem with..?
Didn't faced this problem myself. Maybe because Im not using ext sd card.
5. Should I flash a custom kernel too? If yes, which one and why?
Didn't found any need to do so, stock CM kernel works just fine for me.
Thanks to you for reading through all of this and please be kind enough to answer. :silly:
Heres the link for pixel experience by faserf
http://forum.xda-developers.com/android/apps-games/google-pixel-experience-launcher-dialer-t3478907
2. Twrp recovery by squid2
3.CM14.1 by seraph08 (reubenPCA is the thread operator)
Here's the link-http://forum.xda-developers.com/moto-e-2015/orig-development/rom-cyanogenmod-14-1-t3492794
4. I faced no such issue in cm14.1.
5.nope you don't need any kernel, cz the stock one performs excellent.

First of all, thanks bro for the reply.
Have you tried the CypherOS 3.1.3?? That seems good too but is having wifi problem, though in the latest version only.
Everything works fine in the CM14.1 you suggested, right? Even the wifi / tethering, VoLTE and OTG..?
VOLTE is still not available in any ROMs as far as i know, and for everything else works also i had tried cypheros 3.1.3 but i had some issue with that lyk the music would play on loudspeaker even if my headphones were connected(it also showed in the status bar , the headset icon after i connected my headphones) so yes i found cm14.1 better than cypheros in terms of performance

Thanks mate..!! I appreciate your reply. BTW, stock Marshmallow does support VoLTE, but since its my secondary device, I can live without that.
Yeah stock mm firmware supports VOLTE but then my phone would lag a lot on stock, so it's really difficult to stay on stock and that on jio half the calls wouldn't be placed due to interconnectivity issues, so i used stock for hardly 2-3 days.

I have being examinating the ROM and I have seen less things in configurations than in Dhinesh´s version, but they are minimun compared to the App2SD. Now I have liberated a lot of memory, THANKS KARTHICK!

Audio not working on S5310
Rom works great on my S5310, I use my phone principally as a modem and for messaging but I recently got a new plan from my provider that gives me 1000 minutes of telephone credit, it was then that I realised that the speaker and microphone are not working, it does vibrate though. Any one know how to fix the audio? or I will just have to wait for a new rom for the S5310. I do use the camera and the CM12/13 versions currently seem to have problems with that.

Tried CM 6.0.1 by appav but device overheats even on standby mode.will try AOKP.......
I think I used all the available roms here and I am slightly disappointed. Each of these rom has a lot of errors and underdeveloped.
Both 5.1 and 6.0 at the beginning of a great work. All nice and beautiful works, but after a few days / weeks of use there are mistakes and there are more and more.
A) I'm currently using 6.0.1 and after a week of use:
- Frequent suspension of the touch screen (software).
- Rom memory permanently at 1.1 GB (1.3 GB available), which causes the system begins to slow down much (I have literally several applications uploaded).
- Lack of front camera and the rear camera outside very often turns off only helps remove the battery)
B) previously had the 5.1.1:
- Need less RAM (700-800 MB of applications)
- After uploading fix, and so there were frequent errors sim card
- Speaker on one sim card did not work during the call.
several times I installed accordance with the instructions, the system worked well for a few days, then returned errors.
In conclusion I would like to finally upload a stable rom!

Stuck On Checking For Updates
Good morning, I have noticed each time I try to install this ROM, it hangs on the "Checking for updates" step during the initial start up of the ROM. The only way around it is to power the phone off, then when I power it back up it goes bacxk through the initial set up process again, and again hangs on this step.
Any ideas how to get around this or to even bypass that step entirely?
My method to getting V4A working on this Rom
I Used ( lineage-14.1-20170624-UNOFFICIAL-himawhl )
which actually installed way faster, booted up even faster then Bad Boyz.
And sounded great.
The Process===
What I ended up doing was do a Wipe, then Flashed the Rom and then afterwards I flashed
SuperSU 2.78 ( but I think it will work with the ( Super Su 2.82SR5 ),
So after that was done I flashed ( V4a+2.5.0.5 )
After testing
LTE Data works, idk about calls or texts or even, I didn't get to test it that far just yet.
i have tested the camera some cool features but its not the 60FPS im lookin forward to still,
and teven then its so much smooth than the s6 and Note 4 on deodexed roms and even then
before i tired out liquid smooth.
So what I'm thinking now is whenever i Can i will try to..
Flash same rom again, and then Flash SuperSu 82SR5 Upgrade, and then Flash V4A, reboot, Profit??
go back into TWRP or REcovery and FLash g Apps....profit??
For me it's a bit of ways to get into recoverys,
because for my method i went into recovery by using, ADB reboot Recovery
since my volume dowbn button works on and off, so Adb Debuggin in Developer options.
I'd prob look for an app to have those extra power option menus and then probably, a more 60fps camera apps.
Or Idk if you have any suggestions i will try it out definietly.
Wow.... ROM works great for me. So far everything works smooth. I'm just facing 2 minor issues:
1. Bad notification sounds. Sound really distorted unless notification volume reduced to 60%. YouTube etc sound perfect at full volume so nothing wrong with the speakers.
2. Weather and Time Widget doesn't pick up any weather services (installed Yahoo, AccuWeather etc., to no avail)
Anyone else experienced this... or any ideas ?

Hey guys, need help here. I'm unable to root the ROM. Downloaded files to flash SU "addonsu-14.1-arm64-signed.zip" from here: https://download.lineageos.org/extras
and flashed it, to no avail. Then tried removing it by flashing "addonsu-remove-14.1-arm64-signed.zip", rebooting, and flashing again. No luck.
Also, tried installing V4A hoping that it would solve the bad sound quality on notifications etc.... but need root for that to work, so am kind of stuck.
Any tips?

Hello
here is a Android 10 release of crDroid 6.5 from 16.4.20 for download:
https://yadi.sk/d/TD-kDw6UvZbvoQ
I got it running on my Mi 9T, without any issues.
Even the fingerprint sensor works very fine, its my daily driver.
It has lots of customization options
It is official rom?
Can I flash it on indian k20
I dont think its official.
I am not the developer , but I am very happy with crDroid on my Davinci.
I tested very much other roms, every one had issues with something.
Mostly with the fingerprint sensor or the customization options.
With a backup from your previous system its worth a test
Is it smooth ROM like, for instance, Pixel Expirience? Does ANX Camera works in it? Which gapps do you use on this ROM?
does all functions works ok?
I didnt find anything what is not working.
Pixel Exp. is nothing for me, to less options. But yes, it runs smooth.
The battery life is amazing.
I use opengapps nano, because when pixel launcher is installed the orignal laucher has problems.
And the gcam port from urnyx works very fine. Havent anx cam installed yet.
Volte/vowifi working? And stupid question but does it ask for FP when double tapping a notification or just pin?
Used to use crDroid back in my Samy S2 days so interested to see how its come along.

Then who is the developer !!!
I found the download with Google.
Dont know whos the dev.
Crdroid is my absolute favorite rom , hope there will be an official build on the crdroid page
@nikc0069
You can unlock with fingerprint or pattern.
How can I test Volte/vowifi ?
Volte is on per default, Wi-Fi calling can be enabled
Found the ROM on 4pda, the develop name is Razziell of that forum, this is the know bugs written on the post:
ANX camera not supported!
After making calls on the bt headset while playing music, you need to reconnect the headset / headphones, since the audio stops playing (the same applies to the GU)
It is better to write about the problems found in telegram (link in the profile) or in qms.

Cannot be activated means that you don't see any devices on the list?
If that's the case it means you need to enable the wireless display setting within build.prop. It may has been disabled because your device doesn't support it very well or because it causes greater stability issue with the ROM. So think about it before doing any modifications.

Thank you i tried adding the line in the build.prop but still not working it was working perfectly with stock rom but it will not with the 3 custom roms now i am using crdroid but no luck i even used the mirror enabler but is not compatible with android 10.
