Help!! - Need assistance in moving to Lineage OS 14.1/15.1 - Xiaomi Redmi Note 3 Questions & Answers

Hi Folks,
Need some serious assistance in getting Lineage OS(14.1 / higher) and other custom ROMs in the Future.
Current state & issues :
1) current state :
--ZCX TWRP recovery installed (Flashed via EDL mode)
--Locked bootloader(yes, its locked)
--Lineage OS 13.0(marshmallow) installed, Up and working
2) Issues :
--SIM 2 undetected
--VoLTE doesnt work
--old ROM
History of my Rooting/tinkering :
1) Did I Unlock boot loader officially /unofficially ?
--Unofficially - ofcourse!
--As you all know that Xiaomi has dropped unlocking support to this phone, I waited for a good 4 months( until september 2018) before i tried the unofficial unlock method, very reluctantly though.
Method of unlocking :
-- https://www.youtube.com/watch?v=2FmaCdnLi58&t=5s (i was able to unlock the bootloader, install sTWRPv2 for Kenzo)
--MIUI 7.1.8 Global rom worked fine along with sTWRP v2
--FLashed official Lineage OS 14.1 (from Strixx). It went into eternal bootloop.
--Flashed ASOP/pixelrom/ressurectionremix/Los15.1/16.0 and they all went into eternal bootloop.
(I did not flash any firmware)
--Shutdown my phone, charged it to 100%
--Then followed this ZCX TWRP recovery method: https://www.youtube.com/watch?v=5EDoPtCe3C0 [or] https://forum.xda-developers.com/redmi-note-3/how-to/unlock-unofficially-install-zcx-twrp-t3586778
--Flashed Lineage OS 13.0 ( i thought it may work)
--Lineage OS 13.0 from https://forum.xda-developers.com/redmi-note-3/development/rom-lineageos-13-0-t3533744
--Finger print sensor didnt work, No SIM card detection.
--Flashed CM13-Firmware.zip(from Strixx), wiped cache, flashed LOS 13.0
--Wola, OS booted up, worked.
--As noted in the begining of this thread, bugs.
--Tried flashing LOS14 firmware+LOS14.1 from strixx, no go
--Kept getting Error 7 - which means my recovery is incompatible???
--I wanted to flash another recovery - specifically designed for KEnzo, by strixx.
--Hit the wall - Since I flashed ZCX TWRP from EDL mode, it locked the bootloader again.
--Now ***Only Cyanogen mode 13.0*** works now, with bugs of course!
Now that i've come so far... the questions for Mods/devs who can help me out!
A) what is the ask ?
--No MIUI, complete movement into Lineage OS 14.1 / 15.1
B) Will you flash other roms int the future ?
--Yes, would love to when i have the freedom to do so
C) do you need root access?
--Not an absolute necessity
D) can device boot into EDL mode and be detected on laptop ?
--Yes (using 2016.08.30.0 flash tool), windows 8.1 x64
E) do you have any backups ?
--No, i forgot to do it.
F) Current state of the phone ?
-Unlocked unofficially
-Flashed ZCX TWRP
-Locked bootloader again(because of ZCX TWRP)
-Lineage OS 13.0 works fine, CM13.0 Firmware was flashed before i flashed the ROM.
-VOLTE does not work, SIM2 does not work. SD card works.
G) Can you get the phone to service center to start afresh for a good movement into Lineage OS/ custom ROMs?
--Willing to do so
H) how experienced are you at this ?
--I'm a noob. Any help will be greatly appreciated.
I) Have you read other threads/forums to fix this ?
--Yes, i was extremely confused after seeing everyone of them and decided to seek help.
J) Will this phone be my daily driver ?
--Absolutely yes!!
K) Any specific links/files that you need ?
--Please point me to it, will try to get the link/files.
L) worried about battery backup ?
--Yes!! i would prefer a stable ROM with good battery backup & network coverage , over extreme performance.
Is this a duplicate ? please point me to the right thread. i'm all ears!

Install Miui 9 via fastboot or edl
I recommend you RED WOLF recovery
Resurrection Remix or AEX Nougat rom (for best battery backup)
Agni Kernel
In my opinion your problem is or Firmware or Recovery.
See in the forum for links, im in the phone now.
If you with this cant boot nougat rom i suspect of hardware issue.

Hi, I have an old Lolipop bootloader which is unoficially unlocked and I just updated to redfox TWRP
I have on the phone now perfectly working "ressurection remix" android 6.0 marshmallow but with unoficially unlocked Lolipop bootloader
so I understand this: if I upgrade to the last firmware without the emmc file it means that it won't upgrade my bootloader at all, that means it will remain the old Lolipop one unoficially unlocked
so my questions are:
1).will I be able to flash Nougat or Oreo custom ROMS if I upgrade the firmware without emmc file but I will STILL be on very old Lolipop bootloader? (as I understand newer Oreo ROMS need newer bootloader)
2).or I'm better updating the firmware with emmc file included, that means it will lock my bootloader but will also upgrade it to the newest bootloader so I'll be able to install newer Oreo ROMS ?
regarding my second question, I would use the 2nd method in this thread to install custom ROMS with locked bootloader https://forum.xda-developers.com/redmi-note-3/how-to/kate-guide-install-lineage-os-locked-t3546154
please advice what is the simplest way for me to install OREO custom ROMS with a very old unoficially unlocked Lollipop bootloader
thanks in advance!

MIUI Fastboot roms :
http://en.miui.com/a-234.html
★ Redmi Note 3 SD Latest Global Stable Version Fastboot File Download
★ Redmi Note 3 SD Lastest Global Developer Version Fastboot File Download
which one do you recommend ?
Also, could you please refer a guide for flashing fastboot ROM via EDL mode ?
Once i flash this fastboot ROM, i guess it will lock the bootloader again and I need to unlock it unofficially. If I were to unlock it unofficially on the latest fastboot ROM, how would i go about doing that ?
the only method i know is to flash 7.1.8 ROM with modified emmc file and then unlock bootloader. will this take my firmware back in time and be incompatible with newer custom roms ?

Please dont do that. The issue with ZCX could be that its designed for Android M. the newer ROMs will have issues since its not updated to suit android 7.1/8.1/9.0
I'm stuck with ZCX and none of the 7.1/8.1/9.0 ROMs are getting installed. I unofficially unlocked the bootloader, waited for 4 months.
This guide is good, but it does take you back to 7.1.8. if I can avoid that, it would work for me and you:

Until the bootloader unlock, its simple. beyond it is a little muddy.

Bump, please advise on this.

I have installed MIUI 10 based developer ROM 8.9.13. Did a clean wipe, everything is restored and working as expected. Could you please recommend an article for unlocking bootloader unofficially ?
OFficial unlock isnt working for me. I've been trying that from May 2018.

Dude I have officially unlocked. Its been 2 yrs i had been to miui global rom. Since then I m just flashing firmware emmc to keep my device uptodate.
I have never tried and no idea how to unlock unofficilay.
But if u need proper advise then install telegram chat app. All the xda followers and devs are more active on telegram compare to xda.
Just install telegram and search keyword like redmi note 3,
kenzo development,
kenzo news,
kenzo roms,
miui roms. Or any other specific group related to custom rom like resurrection, aex. U will get quicker response .

You can try unofficial unlock method if you really want to unlock boot loader.
I have been using my kenzo without unlocking boot loader with Redwolf or pitch black recovery and AEX N unofficial by pzqqt.
If you want custom ROM you can try without unlocking BL.

Hi Folks,
I’ve officially lost my Redmi note 3. It was snatched away, while waiting for a taxi. Anyways, Leaving a suggestion here if someone is unlocking Redmi note 3(kenzo) in 2018.
Before anyone starts!! Please read this once and then start.
 All credits to original developers
 I’ve just put in steps to unlock and install TWRP after multiple failures
 This unlocking is only for Kenzo. 32GB/3GB Indian Redmi note 3 model
 Try at your own risk
 Is there an option to revert to stock if you are fed up of trying ? Yes. Flash the Global stable ROM using this method : http://en.miui.com/thread-235865-1-1.html
Pre-requisites:
A) I don’t recommend ZCX TWRP method, it locked my bootloader again.
B) Disable driver signature enforcement on windows
https://www.howtogeek.com/167723/ho...8.1-so-that-you-can-install-unsigned-drivers/
C) Ensure that you have the phone connected to the PC always, until the end. Disconnecting it in the middle of a step could take you back to Step 1&2
D) Use only the older Mi flash tool - v20160830(which has Qualcomm Drivers - ), *NOT* the newer version of unlock tool
E) Charge your phone to 100%(to be on safer side) before start
F) Download the necessary files and keep them ready. *DO NOT keep the phone in EDL mode and then, start searching for it! Your phone does not charge in EDL mode*. if your phone shuts down while flashing, it will cause bigger issues.
*MIUI DEV ROM / https://en.miui.com/a-234.html
*(optional) Cofface TWRP by feds64 / http://en.miui.com/thread-296053-35-1.html
-> You can find “FIX” in the in 30-40 page. Not sure. This works with lineage OS 14.1 too.
*official TWRP / https://dl.twrp.me/kenzo/twrp-3.2.3-0-kenzo.img
*Redmi note 3 bootloader unlock files / http://en.miui.com/forum.php?mod=attachment&aid=Mzc0OTg4NnxlYjIwYjYxNnwxNTQxNjY1MDQ5fDB8MjQwNzgxOQ==
* Lineage OS 14.1 / https://download.lineageos.org/kenzo
*MIUI Flash tool 2016.08.30: http://api.bbs.miui.com/url/MiFlash [or] https://androidmtk.com/download-xiaomi-mi-flash-tool
* Open Gapps pico 7.1 , ARM x64 – https://opengapps.org
G) Create “C:\RedmiNote3\” folder and place all the downloaded files(ROMs/unlock files/TWRP etc) there. There should be no spaces in the folder path.
H) Ensure that you select “clean all” in the mi tool, always. Do NOT select “Clean all and lock”
I) Certain articles may be redundant, but more information always helps. IT took 2-3 days to get all the files that I need. If you cant find something that i’ve listed, let me know. Will try to get it.
Quick overview of the install sequence :
1) Reboot phone to EDL mode
2) Flash the Developer Fastboot ROM from Xiaomi
3) Set up the phone(with / without Mi account)
4) Enter EDL mode again
5) Unlock phone unofficially
6) Copy Lineage OS 14.1, open Gapps (x64 ARM – PICO) & TWRP in the memory card
7) Enter Fastboot mode
8) Flash TWRP official
9) Advanced wipe in TWRP : Wipe data, system, dalvik/cache, internal storage
10) Flash Lineage OS 14.1
11) OMG!!!! the Phone isn’t booting, what can I do to revert to factory settings?
Follow steps 1 & 2 and you are good to go!
Procedure that I followed :
I. Disable windows driver signing on your windows machine
II. Download redmi note 3 Developer fastboot rom(Global DEV) : https://en.miui.com/a-234.html
-select “★ Redmi Note 3 SD Lastest Global Developer Version Fastboot File Download”
III. Enter EDL Mode of Redmi note 3
-shutdown phone.
-Press Volume down+Power button for 5 seconds, you will see Mi Bunny in fastboot mode
-Use https://forum.xda-developers.com/redmi-note-3/how-to/guide-reboot-to-edl-mode-fastboot-test-t3398718
Download : https://www.androidfilehost.com/?fid=24591000424940129
-execute Reboot.bat
-Reboot to EDL mode (Red LED flashes)
-Your phone will show up in Windows OS’ “device manager” as Qualcomm 9008 diagnostics(it should come up this way)
IV. Flash the DEV Rom, using mi Flash tool : http://en.miui.com/thread-235865-1-1.html
a) Version of mi flash tool required: 2016.08.30(this worked for me)
b) Install MIUI Global DEV ROM via EDL mode by following instructions in the MIUI FORUM
V. Setup your phone after flashing DEV Rom. Tap “build number” 7 times to enable developer options
VI. Developer options  (I was signed into my MI account while unlocking bootloader UNOFFICIALLY) no issues there!!
VII. How to unlock unofficially ?
-Follow this : http://en.miui.com/thread-2407819-1-1.html
a) Follow First 7 steps
b) unlocking phone using following commands :
“Fastboot devices”
“fastboot oem device-info”
“fastboot oem unlock-go”
Quick check to see if unlocking worked “fastboot oem device-info”
c) “Flasher toolkit” by Feds64 seems to be broken, Install TWRP manually.
VIII. After you unlock your phone, reboot to Fastboot mode
IX. Flash TWRP official, manually
Download : https://dl.twrp.me/kenzo/twrp-3.2.3-0-kenzo.img
commands to flash TWRP :
“Fastboot devices”
“fastboot flash recovery C:\redminote3\twrp-3.2.3-0-kenzo.img”
X. Reboot to TWRP without booting to MIUI
“fastboot boot recovery C:\redminote3\twrp-3.2.3-0-kenzo.img”
“Swipe to allow modifications”, but ensure that you DO NOT modify partitions.
XI. Do you see CHINESE text in TWRP? switch language : https://www.youtube.com/watch?v=vxPeYJYsUYU
XII. Ensure that you have Lineage os 14.1 downloaded and stored in a memory card.
https://download.lineageos.org/kenzo
In TWRP, you need to do “advanced wipe”
Dalvik cache,
cache,
internal storage,
data,
system
XIII. Flash Lineage OS 14.1, Open Gapps – Pico, x64 ARM.
