This thread is meant to address all the common hurdles that are commonly faced by people who are new to treble devices (chef to be specific) and help them to troubleshoot/avoid some small yet critical steps during flashing new ROMs and working with fastboot and recovery in general. It will be continually updated with new stuff as it goes along.
I will be referring to the Motorola One Power and Moto P30 Note as chef only from now on.
The unlocking guide is available in This XDA Thread!
IMPORTANT:
1. Flashing refers to the process of doing a clean flash, with the inclusion of fastboot -w command
2. Latest ADB and Fastboot drivers are required to be installed, else the installation may halt mid-way.
3. Stock ROM refers to the Android One ROM for the Motorola One Power [XT 1942-2]
IMPORTANT: AS OF RIGHT NOW, PEOPLE WHO HAVE INSTALLED STOCK PIE (EITHER VIA UPDATE OR FIRMWARE) WILL NOT BE ABLE TO USE ANY OTHER ROM OTHER THAN THE STOCK PIE ROM. RADIO INTERFACE LAYER IS BROKEN IN OREO SOURCE BUILT ROMS AND THAT CURRENTLY INCLUDES LINEAGE 16 SO PLEASE WAIT FOR PIE SOURCE CODE FROM MOTOROLA FOR THAT TO BE FIXED.
1. I unlocked my chef . How do I flash TWRP in place of the stock recovery?
Solution:Currently you cannot as there is no recovery partition in the device. You have to manually boot TWRP onto the device using fastboot to use it. Follow as directed:
Boot the device into fastboot mode
Use command fastboot boot <path/to/TWRP.img> to boot TWRP temporarily.
2. I am done with TWRP and I want to flash Lineage OS 16 on my chef. I simply flash the .zip archive right?
Solution:No. Before you flash anything,
Take a backup of atleast your EFS and PERSIST partitions using TWRP and off-load it for safekeeping to restore in future if needed. You can also trigger a full backup if you require.
SUPER IMPORTANT: Flash this .zip file to copy the System A/B partitions. If this step is skipped, you will be responsible to brick your own device. THIS STEP IS ONLY REQUIRED ONCE AND ONLY ONCE IN THE LIFETIME OF YOUR DEVICE! YOU WON'T BE NEEDING THIS THE NEXT TIME YOU FLASH ANY ROM. .
After that, flash your dearest custom ROM and get going.
For Lineage OS 16, follow This XDA Thread.
3. I am done testing LOS 16, I want to flash a GSI. Shall I use a stock Vendor Image for the GSI on my chef?
Solution:No. The stock Vendor image is causing bootloop issue in most GSIs. It is recommended to use Lineage OS Vendor to flash a GSI on chef. So flash LOS and then flash your favourite GSI.
Also, Super Important: for those who haven't used lineage before flahing a GSI, it is required to boot Lineage OS first before flashing a GSI.
4. I am done experimenting, I want to go back to the stock image. How do I proceed?
Solution:Follow this XDA thread for it. And don't install OTA updates directly from the device. It will come in the next step.
5. I want to install OTA updates on the stock ROM. How do I proceed?
Solution:Follow this XDA post for it. The installation process is described here. You have to be clever enough to get the appropriate OTA update.

Anyone have flashed GSI ROM? FOr me after flash GSI HavocOS have bootloop :/
DIdn't flash copy system A/B partitions, stuck on bootloop with custom roms.
Watched some youtube videos and didn't read this post before flashing custom ROM. Flashed Custom ROM without flashing A/B partitions. Now I have a phone stuck on bootloop when done anything in TWRP. or I can use my phone with stock ROM installed by fastboot method.
Installing or restoring anything from TWRP results in boot loop.
Restoring the backup I made before flashing, completes the restoration process normally. But when rebooting to system, TWRP prompts me that no OS is installed. If I reboot anyway, its either stuck on bootloop or reboots to recovery and asks me to try again or factory reset, or boots into bootloader mode.
Installing custom ROM begins with Step 1, takes a bit time and starts step 2 and shows completed. Doesn't echos any comments. But when i reboot, same prompt shows saying no OS installed. Reboot anyway and stuck on bootloop or reboots to recovery and aks me to try again or factory reset, or boots into bootloader mode.
Now I installed stock ROM with fastboot method and phone is boots up into system just fine.
Sometimes TWRP can't mount anything.
So am I stuck with stock rom or is there any solutions?
Also, installing stock ROM with fastboot mode showed this error in between scripts
(bootloader) is-logical:xxx_a: not found
and
(bootloader) is-logical:xxx_b: not found
but is able to use the phone just fine with stock ROM.
Hi there,
I read many old threads but I'm as confused as I can be. Some say there's no need to unlock the bootloader because you can just flash TWRP from ADB and root... other say you have to unlock the bootloader first. Anyway, I only find mixed and confused information.
Could someone please recap what should I do? I already downloaded the RR Oreo ROM, ready to be flashed...
Thanks a lot!

So here is a quik guide (skip steps if allready done)
- make sure stock ROM is latest (update)
1. Need to unlock bootloader (to be able to install TWRP)
- do it on moto official site. Just follow the steps there. Read carfeully
- install android sdk at best OR if want save space Google "simple adb installer xda"
2. Install TWRP (to be able flash ROMs or get ROOT)
- download latest version from TWRP site for our model (.img file - need only flash once)
- flash it via fastboot (google for the exact process for our moto on xda)
- boot into TWRP from bootloader menu (recovery in bootloader menu)
4. Installing a ROM:
Connect to PC while in TWRP (here you can backup your stock rom TO SD card, recommend)
- put ROM zip + GApps (GoogleApps - use Opengapps website: ARM32/8.1 for oreo/micro
& Magisk zip for ROOT (dl from xda) on your phone or SD card storage.
If switching ROMs, a clean flash IS needed: (all in TWRP)
Wipe - factory reset
Install ROM zip
Install gapps.zip
Install magisk zip
- boot & profit.
Good luck, ifs something unclear, ask!
peace.
This is a guide to get you from stock marshmallow on the SM-N910v all the way to Lineage OS 16.0 on Android Pie none of the work in this guide is my own end credits go to all respective Developers. I wrote this guide because I purchased a Galaxy Note 4 on eBay, and while I have some basic experience with android modding before I had never used Odin and found the instructions to be scattered and not noob friendly.
*WARNING THIS WILL WIPE ALL DATA*
*I am not responsible if you brick your phone, however if you do you can always try the verizon recovery utility which will download and flash the latest version of stock marshmallow*
Step 1: Marshmallow to Lollipop: In order to unlock the bootloader you must be on Android Lollipop if your phone has already been upgraded to Marshmallow you must downgrade using Odin the first step is to download the stock ROM from this forum post https://forum.xda-developers.com/note-4-verizon/development/firmware-firmware-kernel-modem-recovery-t2942937
YOU MUST DOWNLOAD THE BUILD ENDING IN BPA1
The next step is to download Odin: https://forum.xda-developers.com/showthread.php?t=2711451
Once you have downloaded Odin install the Samsung USB drivers and confirm your phone is recognized in Odin. once your phone is recognized disable reboot after flash and click on the AP button and select the ROM you just downloaded then boot your device into download mode (power/vol down) and flash your device. after flashing your device it will boot loop in order to resolve this you must put it into recovery mode by pressing power and volume up and clear the cache and user data.
Step 2: Bootloader unlock
now you can follow this tutorial to unlock the bootloader, however don’t flash anything wiht odin just yet https://forum.xda-developers.com/note-4-verizon/general/stabilized-process-to-unlock-bootloader-t3375527 (this guide uses this software https://forum.xda-developers.com/note-4-verizon/general/note-4-verizon-bootloader-unlock-t3358913)
Step 3: TWRP
Download the latest version of TWRP from here https://twrp.me/samsung/samsunggalaxynote4qualcomm.html make sure you download the .tar file and not the .img flash this in Odin by selecting AP and choicing the TWRP file, once again make sure auto reboot is not checked when this is done your recovery should be replace by TWRP
Step 4: Lineage OS 16
According to the post on XDA you must be on marshmallow in order to install lineage OS 16 however I didn't upgrade to marshmallow for fear of losing my unlocked bootloader and it works just fine this makes sense because you were flashing over all of the stock firmware and I assume it just said this because that's what it was tested on. Use https://forum.xda-developers.com/note-4/snapdragon-dev/rom-lineageos-16-0-t3900807 make sure to download the correct modem file and flash it using AP in odin, then just flash lineage and opengapps pico 9 ARM in TWRP, clear cache between each flash, follow any guides on the original post, this part is relatively straightforward.
Step 5: success!
Everything should be working now and you can begin to configure Lineage OS however you want!
Thanks for nice concise guide. Lot of what's on XDA discussion assume good deal of prior knowledge on the reader and it's easy to get lost. Yes I can confirm that even after unlocking boot loader on lollipop, flashing marshmallow stock rom will put you back on stock locked bootloader. It's good to know that lineageOS 16 works fine on verizon Note 4 when flashed on lollipop firmware with unlocked bootloader. I followed thread for lineageOS 18 for verizon Note 4 and there are many issues which looks like has not been resolved and debug efforts have mostly ended. There is only so much time someone could devote to sustaining volunteer projects such as lineageOS ports for Note 4. I tried lineageOS 18 on my Note 4 N910V and couldn't get it to recognize my sim. So best bet is still older lineageOS based roms flashed on lollipop firmware with unlocked bootloader.
Since in my last post I made a complete mess out of my first time trying to root my K20 and install lineage I wanted to my make a separate post so that I can list all the steps I need to take to correctly setup my phone how I want it.
What I actually want
A rooted device
Lineage OS
Minimal excess files (A clean Install)
Current Steps
Unlock and flash recovery
Backup
Format Data! (It's important if you come from Miui)
Install Q Firmware + vendor
Install LineageOS followed by gapps
Reboot into system and setup device.
Reboot into recovery and flash magisk
Profit???
Feel free to tell me how stupid I am and what I need to add to the list or steps I should take to make this process better.
I also dont know if its possible to get recovery and rom on android 10 versions.
Thanks
Did these steps not work?

They may work as it but I was just wondering if anyone could go into more detail or if there was a better approach and from what Kollachi said there clearly is a better way that what I said.
Since I'm in stock ROM and haven't ever flashed AOSP ROM in this phone I'll just back off lol

I like the details steps but I have a few questions.
(Unlock and flash recovery) From what I can tell there are two recovery's Orange fox and TWRP
(Format data) Just format data or are there other sections I should format/wipe
(Install Q Firmware + Vendor) I have no idea what Q firmware is or what vendor you are referring to
(Install Lineage + gapps) Is there a specific version from the Mi 9T pro since the official site doesn't list it
Any of the two recoveries will work. Q firmware means Android Q. Wile data/cache dalvik that's it. Regarding firmware, there's a clear topic of Lineage OS in K20 Pro forum which is still in unofficially state

1. You can take what you want. Orangefox is based on TWRP.
2. Format data is needed if you come from miui. If you did it you are good to go. But it wouldn't be false to wipe system, dalvic, cache
3.https://downloads.akhilnarang.me/MIUI/raphael/ --> Take 10.4.6.0 or 10.4.8.0 (Android 10 = Q)
4. No there is no specific version.

I would recommend the latest TWRP from here
https://forum.xda-developers.com/k2...icial-twrp-xiaomi-redmi-t3944363/post79823568
The dev is an official TWRP dev, so this version, or something very close to this, is likely to become official in the future.
OrangeFox is a heavily modified TWRP and has a lot of added functionality specific to MIUI. If you wanted to stay on stock MIUI, but debloat and have root, etc. then OF would be the better choice, as it has functionality that lets it play nicely with MIUI (it can remain installed when OTA updates are installed)
As someone new to flashing on Android, I would suggest downloading a 10.4.x fastboot ROM from the site I pointed to in your other post, then follow the same procedure to flash the ROM.
Make your choice based on Kollachi's info and what's important to you (HD Netflix - choose Indian, or a working NFC - choose Chinese)
However you MUST change the flash option to 'clean all'.
At this point you've got a nice squeaky clean starting point.
Boot into the ROM at least once, though it's not necessary to go through all the setup.
After that follow Kollachi's steps but you can now ignore the step to flash vendor and firmware as it's all part of the fastboot ROM already flashed.
Wipe cache and dalvik, format data.
There is no official LOS for this phone yet. Hopefully it will go official in the future.
For now just get the current Android 10 based LOS from here.

When ever I think I have the process memories and I follow the steps on my screen I still somehow **** this up and I cant understand how.
My current steps include
Flash the fastboot with the ROM that you linked me in my first post
Flash the recovery with TWRP (Every time I have then tried going back into TWRP is failed to work and prompted the original MIUI recovery)
Install the TWRP zip from custom recovery to try and fix the issue above (Only had this work once on orangefox and then never had success again)
So now I try to just flash the recovery and boot to it using CMD and it works fine
Move the lineageOS files from my PC to the phone SDCard
If I wipe data and the caches as suggested then the lineageOS zip is now go and I am back to flashing the fastboot ROM to restart the process
I know this might seem like im either stupid or just not getting it but could you or anyone else please make a bullet pointed list with links to what I have to download in order to actually achieve this since I cant do anything correctly even when trying to follow the steps.
(Im going to sleep since I have been trying to do this for hours now and I will check reply's in the morning.
Thanks for the help so far EVERYONE

I just told you what I have done and I'm running it so far without issues.
Robbo just said you should flash the whole Chinese or indian rom but I don't like his steps because:
1. File is much bigger
2. MiFlash is just meh
3. If you forgot to change the flash process you are bricked if you don't take the correct firmware for your phone.
Default option in Miflash is set to "Clean all and lock". Every time you use it, you will need to change it into "clean all" or something other.

Yes flashing the whole fastboot ROM does add the risk, if you forget to change the flash option, but you are guaranteed a clean slate and so less likely to have any niggling issues that nobody else has. I would bet large sums of money that many of the issues you see on here, where only one person has some problem and everyone else is fine, would be solved by fastboot flashing MIUI before installing the ROM of choice.
If you know what you're doing and know when you'll be OK with what you've got and know when it's best to start clean, then going with the vendor and firmware is easier.
But if your unsure and new to flashing on Android phones, I will always suggest go with the overkill and know you've got the clean slate to start with.

It's sounds like the main issue is stock recovery is being restored. This is something that MIUI will do when it boots up.
When you first install TWRP you cannot boot into MIUI before booting to TWRP as you instantly lose TWRP. So you need to boot into TWRP first in order to do something to prevent it being overwritten.
Options are
1
Code:
fastboot boot TWRP.img
2 Use the button combo whilst still in fastboot - power and vol+, hold both until the phone vibrates and the initial logo appears.
Now to keep TWRP you need to either flash a custom ROM, flash Magisk or flash the dm-verity script.
In your case you want to flash LOS, so now you've booted into TWRP go ahead and continue with the steps given.
Also, wait until after you've formatted data before copying everything over. You can access the phone as an MTP device when in TWRP, so you'll be able to connect it to a PC and drag everything across, or you can stick everything on a USB OTG pen, if you have one, TWRP can read data from them too.

The exact problem I have is that I cant transfer any files to the device after formatting the data. I follow the steps correctly and I get into TWRP successfully and then everyone has told me to format the data then install lineage but I cant install the OS if formatting the data removes it.
Get device into fastboot
Flash revocery with TWRP
power the device off
hold volume up and power
boot into custom recovery
format data
move lineageOS onto my device
install lineageOS
reboot
done.
This is the list of exact actions I am doing with no results is there something I am missing or something that is in the wrong order.

After format data, reboot your device into recovery again and transfer LOS, gapps and all files you need.
Format data kills the storage.
I always used to reboot from TWRP back in to TWRP after formatting data, but I've recently seen someone saying that they just unmount data then remount it again. I haven't tried it myself but it certainly makes sense and would be quicker too.

Yes I did that and it worked, unmounting and remounting helps detect the storage in PC

hello, I used to be a custom ROM junkie in the past but after some time i got bored and never did it again.
now looking at my current device which i never installed a customer ROM before its quite old as its running Android 8 and i would like to jump to 10 or 11.
I am confident i understand the process but its been a few years and i have some questions:
-for example this is the 1st device i encrypt so i am not sure if this affects.
-the device has no custom recovery so i have to start there but not sure if i have to remove encryption or if its ok.
-Also i would like to see if you have any advice for me or somehting i should pay attention beside install TWRP, format all but storage and install zip file for custom ROM
Thanks

So, you'll need to upgrade your firmware to 9.0.6 because all the latest ROMs require it. Take your time and carefully read https://forum.xda-developers.com/on...5-0-8-firmware-barrier-t3941164/post79758055.
You do not need to remove encryption (depending on how you upgrade your firmware).
If you've got a locked bootloader (which I'm expecting you do), them you need to unlock it so that you can flash TWRP. And unlocking will wipe all data from your phone. So backup everything you want to keep to your PC.
If you don't boot into recovery after flashing TWRP and install a patched boot image (see https://forum.xda-developers.com/on...ty-disable-oxygen-os-t3922324/post79357241)or flash Magisk, and reboot your phone, you'll lose TWRP because OOS automatically restores the stock recovery.
So the order is:
1. Backup
2. Unlock bootloader
3. Flash TWRP
3. In TWRP flash patched boot image (remember you're still on OOS 5.x so use the right one!) or Magisk.
4. Have fun moving to a custom rom.
