Custom Rom Installation help - Lenovo K6 / K6 Power / K6 Note Questions & Answers

Hi guys
I am Sujit and I have a Lenovo K6 power rooted with TWRP installed.
Android version- 7.0
Model- Lenovo k33a42
Android Security patch- May 1, 2017
BaseBand version - JO.2.0.c1-00122-8937 K33a42_DS
Kernal Version - 3.18.31-perf-gdedd3c8
Build Number - K33_S223_170610_ROW
I want to install a custom rom. Do I need to unlock any boot loader or I should just download the rom and flash through recovery.
Regards,
Sujit

You have installed twrp then your bootloader must be unlocked, if you have locked it manually then you have to unlock it before flashing custom rom, as you might loose your current OS too, it will be better to unlock bootloader, take nandroidbackup from current os to prevent any undesirable situation, before flashing clear, system, data, delvik cache and then flash, select appropriate GAPPS to flash after rom

How to Root OP2 running on the latest update 3.6.1?

I recently downloaded the latest upgrades to the firmware. Need help with rooting this device now. It's running Oxygen OS 3.6.1 and Android 6.0.1.
u can use same methods .. like unlock boot loader and flashing any custom recovery!
You need to unlock your bootloader, then flash TWRP recovery through fastboot, and then flash Magisk or SuperSU through TWRP.

Moto G4 Plus (XT1644) Bricked

Hey, so I wanted to install a custom ROM (LineageOS 14.1) anyway, I found this site that was showing me how to but first i needed to unlock bootloader and install TWRP, i clicked on the steps for that and it brought me here:
https://devsjournal.com/how-to-root...to_unlock_Bootloader_of_Motorola_Moto_G4_Plus
I followed all the steps on that page, even installing the SuperSU, but this is where the problem began. After rebooting from installing SuperSU i was stuck on a black screen (not even backlight) and a white blinking LED light next to the fingerprint scanner. I began to look around for a fix and i found this site:
https://forum.xda-developers.com/2015-moto-g/help/problem-boot-flashing-supersu-t3507127
I followed the steps but nothing worked. Then i tried this:
https://forum.xda-developers.com/moto-g4/help/troubleshooting-twrp-boot-loop-ota-t3714325
but that still didn't work. Flashing a new ROM does not fix the problem, and it seems nothing will. I am able to get into the bootloader and I am also still able to get into TWRP but i can't boot into ROM. I need help.
I should have attached this before but here is a picture of the bootloader. After typing in all those command the only thing that changed was the yellow text that says Software status: Modified
1) What ROM are you trying to flash onto your device?
2)The issue here appears to be that you've rooted on the stock ROM - what those pages don't mention is that those steps only work for Marshmallow stock ROMs - attempting to root on the stock Motorola Nougat ROM may cause you to bootloop and you need a custom kernel to root on stock Nougat ROMs. One way around this may be to flash a custom kernel such as ElementalX 2.0.1 https://forum.xda-developers.com/moto-g4-plus/development/kernel-elementalx-g4-0-01-t3424836 then attempt to boot. You can boot to TWRP, connect your device to your computer, which should show up as internal storage. There, you should be able to copy a download of the custom kernel to your device and flash through TWRP. If you made a backup before rooting, you could re-flash just the boot (kernel) partition to restore a clean stock kernel then attempt to flash the custom kernel and then root.
3)You could alternatively boot to TWRP and flash Lineage. You do not need root at all to flash custom ROMs - just an unlocked bootloader. Root for installing custom ROMs is unnecessary. Be aware to flash the Lineage build matching your TWRP (i.e. 32 bit Lineage if you're running the official TWRP or any other 32 bit TWRP recovery for athene, 64 bit Lineage only is flashable with the 64 bit TWRP, else you'll get an error 255 on flashing). As always, flashing a new custom ROM requires a /system, /data and /cache wipe at least - possibly an internal storage wipe, so back up to your computer or the cloud as necessary.
4)As for the modified status, that may have been from rooting on the stock kernel. That can disappear if you were to flash a stock OTA onto your device, but that would mean flashing the NPJ25.93-14.7 Sept 2017 security patch stock ROM (latest leak we have for XT1644 devices as far as I recall), and then taking OTA updates up to April 2018 which may be risky.

Yea i should have been more clear on what ROM i was trying to flash, i wanted to flash LineageOS but when i try to flash it and boot i still get the same problem, the led light just blinks over and over until i unplug the phone or go into the bootloader. Maybe i have the wrong version of something? All i know is that the phone was working perfectly fine before and it is the XT1644 model. It had all its updates up to date but i just wanted to install LineageOS, i do now realize that you don't need root to flash a custom ROM but also i don't know where to find files for the kernel you are talking about, I also did not make a backup (lets just say im pretty stupid and i know i should have). If you have any info or need any more to further assist me, let me know. Thank you for responding!
So i tried flashing the custom kernel and it looked like everything was working, but the phone still won't boot, it just flashes the LED light, also i reinstalled LineageOS after wiping all the cache and internal storage and stuff but it still hasn't worked.
Hey, i got good news, i was able to get the phone to boot by downloading and following these steps here: https://forum.xda-developers.com/mo...e-npj25-93-t3549369/post70843323#post70843323
The phone now is working and i will attempt to install LineageOS once more. Thank you for you help!

Another soft bricked Moto g4 plus XT1642

Hi all,
So I am new to the game, I had an old(ish) phone and attempted to root the device. As some of you might have read on here before, I failed, I thought I had followed all the correct steps. I used the following steps as a guide: (from the unlockr). After attempting to install supersu I was left with a black screen. I can however access my recovery mode in bootloader, the thing is that bootloader is the only thing I can access. I cannot access my moto g4 plus via USB on windows, but for some reason I can access both internal and external memory on a mac. I can see the supersu version, my TWRP etc. I was wondering if someone could help me out, I know this has probably been posted before but I have not been able to find a possible solution as of yet. Thanks in advance
Is your device running stock Nougat (7.0) firmware? If so, then attempting to root on the stock Nougat Motorola kernel may result in a black screen and failure to boot, which appears to be what you've experienced. What those guides generally fail to mention (as they're quite old) is that rooting on the G4/Plus running Nougat requires flashing a custom kernel before you root. Failure to do so appears to trip the anti-rooting measures built into the stock kernel. A more recent guide that I've used for a stable root on a G4 Plus is this https://forum.xda-developers.com/mo...de-root-moto-g4-plus-supersu-android-t3587918 Bear in mind you do not need root to flash custom ROMs whatsoever, just TWRP.
If you can still access TWRP, you may have a way out. One thing to try is to flash a custom kernel onto your device - ElementalX is a good choice. https://forum.xda-developers.com/moto-g4-plus/development/kernel-elementalx-g4-0-01-t3424836 for ElementalX v2.0.1 for stock . Download the kernel to your computer, ensure your device is connected to your computer and booted to TWRP, and copy the custom kernel to your device. Try to flash the kernel and then see if your device boots.
If your device still fails to boot, you could try flashing the stock kernel from your backup (you did make a backup before rooting?) or if you're running a more recent OS build, I've uploaded the Feb 2018 and April 2018 security patch stock kernels here: https://drive.google.com/drive/folders/0B-GUyOfb8OgzcUl1NUtHYWNIR2M To flash this in general:
a)Download the kernel boot.img to your device.
b)In TWRP, tap Install.
c)Tap Install image at the bottom of the screen.
d)Navigate to where you downloaded the boot.img and select the image file.
e)Target the image to boot (not recovery).
f)Flash, and wipe cache.
g)Reboot and see if that works.
If those don't work, restore your backup if you made one or you may have to re-flash your stock firmware - you do not have to re-lock your bootloader or wipe your device with this re-flash of the stock firmware.

Which TWRP version to install?

I have moto x play xt1562 and on this page i see that there are different unofficial TWRP versions. Which version i have to install? ALso, if i have other custom recovery already installed, like linage custom recovery, do i have to take and precautions?
hi peter,
it depends on which image you want to install. since may 2020 there is a bug in twrp which no longer starts the phone with the ota update.
if you want to backup, delete or install your partitions you can install the current version 3.4.0. when you have everything set up you either have to import the updates manually or use its recovery as with lineage. twrp should also work in version 3.3.0 (or any other version before may 2020).
I am currently using the lineage with lineage recovery and it works. should you need more settings for the recovery you can simply boot twrp without installing! thus it is possible to set everything in twrp and still have the lineage recovery because of ota on the device.
if you want the recovery boot (no install) you have to execute this command:
Code:
fastboot boot twrpname.img
cheers
