Well with the fact that i just 'Beginner' in android -developer world i spent two days (read and search) to just know what the right steps to have unofficial rom . So this is not thread from professional it's just what i understand so far . (SORRY FOR BAD ENGLISH)
It's some simple Steps :
1) First you need to root your Device to have fully adminstrator . (This make you can execute terminal order from you and the apps)
2)After you get root install flash tool To do Setup 4 . (Rasher or Flashify)
3)You must UNlocked you bootloader . (So the new rom can edit your boot process)
4)Install custom Recovery [CWM]or[PHILZ]or[TWRP]. (This make you can do zip install from external card)
5)Get your rom download and copy to your external card.
NOW YOUR READY
OK Now my guide is for LG G2 MINI (D618)
The custom rom is [ROM][5.1.1][D618/D620] Cyanogenmod 12.1 Stable
And my phone have OFFICIAL android 5.0.2 lollipop
1) ROOT : FOLLOW THIS GUIDE
http://forum.xda-developers.com/g2-mini/development/root-root-g2-mini-lollipop-t3123652
If it not success . do factory reset and start the root again but this time (don't setup superSU from store and don't restart your phone and IT's su Not Su) this should success .
2) DOWNLOAD THE FLASH TOOL FROM PLAY STORE AND KEEP IT
3) BOOTLOADER : FOLLOW THIS GUIDE (YOU MUST TAKE BACKUP FOR YOUR PHONE FIRST)
http://forum.xda-developers.com/g2-mini/development/bootloader-d620-d618-t3127819
4) CUSTOM RECOVERY : FOLLOW THIS GUIDE (CWM SUCCESS WITH ME) (JUST FLASH .IMG FILE WITH SETUP NUM (2))
http://forum.xda-developers.com/g2-mini/development/recovery-lg-g2-mini-d618-v10c-t2854493
5) DOWNLOAD THE FILE YOU NEED FROM HERE AND COPY TO EXTERNAL CARD AND FOLLOW Installation :
http://forum.xda-developers.com/g2-mini/development/rom-cyanogenmod-12-1-stable-t3175833
NOW IF THIS SETUP'S SUCCESS THE HARD PART IS OVER.
6) Now reboot into recovery mode (you will find this in Flash tool)
in recovery mode you need just two things (WIPE AND INSTALL)
7)CHOOSE "Wipe" CACHE, DATA and SYSTEM (THIS WILL DELETE YOUR PERSONAL DATA AND SETTING AND EVERY THING)
8)CHOOSE INSTALL ZIP FROM EXTERNAL CARD AND CHOOSE FIRST KK_BOOTSTACK_D618_1.1.ZIP THEN cm-12.1-20150828-UNOFFICIAL-g2m.ZIP
9) RECOMMENDED TO INSTALL GAPPS (tk_gapps-modular-pico(uni)-5.1.1-20150824-signed.ZIP)
10) NOW YOU HAVE DONE .. REBOOT YOUR PHONE AND IT WILL DO SOME INSTALL FOR ABOUT 10 MINUTE AND YOU WILL SEE SETTING SETUP ON THE SCREEN
11)F YOU HAVE unstable SIM signal JUST GO TO RECOVERY AND WIPE ONLY CACHE IT WILL BACK TO NORMAL.
THIS IS MY experience ON MY G2 D618 I DON'T KNOW ABOUT OTHER PHONE'S
THANK YOU XDA AND XDA-DEVELOPER'S FOR YOUR HARD WORK .
Thank you very very much for this great explanations!!!
Tried to flash custom recovery with Rashr after unlocking bootloader. Tried CWM, Philz and TWRP and always ended up with attached screen.
What do you think the mistake is? And what do you mean with setup Num 2? Do you mean kernel flash in Rashr?
Thank you!

Make sure that Unlock bootloader process success i have this problem to and i Discovered that the unsuccess unlocking bootloader operation the Responsible for this error as i understand.
Flash custom recovery process deleting the original recovery but because of unsuccess unlocking bootloader Rasher Deleting original recovery but he cannot install the new custom recovery so what i do in this case .
1)Download official android lollipop from here (chose your country ) its KDZ File and flash with LG Flashtool 2014 Here
Now do the setup from the First setup .. and setup Num 2 i just mean Flash Custom Recovery File (Dont use TWRP Use CWM with Flashify .. Rasher didn't success with me ) Hope you make it

this is the stock android recovery that means that you didn't or couldn't flash a custom recovery
make sur you extracted the zip file and flashed the recovery.img with flashify
Hmmm, did everything exactly like you've written until flashing recovery. Now I'm stuck with attached screen when entering recovery...
Any idea?
Thank you!

this is the fastboot screen
the recovery you tried to flash is corrupt make sur the file isn't corrupted and the that is matching your device
i think your device is d620r and your trying to flash the one from the thread [RECOVERY][CWM][PHILZ][TWRP] G2 Mini D618
if you can boot into system reflash the matching recovery TWRP for your device if you can't connect your phone to pc
use fastboot to flash the recovery

don't know what's wrong !! if bootloader was locked you will have a security error on boot not the fastboot screen when enterig to recovery maybe you're doing the wrong combination to access recovery try with an application or with flashify or rasher to reboot to recovery

The same happen with me so I put the general tool for all users and I mentions the successful tools that work with me
Sent from my LG-D618 using XDA Free mobile app
SGP-321 / LTE / pollux
Bootloader unlocked
CM13 installation:
- extracted boot.img and installed by: fastboot flash boot boot.img
- installed CM13 bei "update" from inside CM_recovery
- everything works OK until now.
TWRP 3.0.2.0 instal:
- installed by ADB "fastboot flash boot TWRP.img": sending/writing 'boot': OKAY
- fastboot reboot: rebooting into TWRP
In TWRP/Reboot SYSTEM: this reboots back into TWRP, does NOT boot CM13. Why?
CM13 installed again by "install" in TWRP: this installs CM13 but overwrites TWRP with the CM13_boot.img. So after the installation TWRP is gone and i have only the CM recovery.
Installing TWRP again has the same result as above: no booting of CM13, only booting into TWRP.
How can i solve this?
(PS: on my another xperia, "pollux_windy"/WiFi everything works ok, no issues with TWRP/CM13. )

Use CM13 kernel (boot.img) with TWRP integrated or if you don't have it, flash TWRP to FOTA:
dd if=/sdcard/twrp.img of=/dev/block/platform/msm_sdcc.1/by-name/FOTAKernel

Thanks a lot for the hint!
CM13 kernel (boot.img) with TWRP integrated: unfortunately i have not seen that anywhere mentionded until now. Where could i get that?
I have TWRP 3.0.2.0 for my "pollux_windy" that works fine, from the following download:
https://dl.twrp.me/pollux_windy/
I have been trying TWRP 3.0.2.0 for my "pollux" from the same site:
https://dl.twrp.me/pollux/
Is the TWRP for pollux_windy with integrated boot.img and the one for "pollux" without boot.img?

I actually don't know why it worked for you with windy, as when you flash fastboot flash boot TWRP.img it replaces stock CM boot.img and it won't boot, cause inside twrp.img is only recovery, but not kernel to boot system.
Thanks a lot for this excellent hint! It was a big help and it seems to work now perfectly.
pollux_windy / WiFi & TWRP:
After second thought i have to admit that i do not quite remember how exactly i installed TWRP on this one, it was some 2 months ago and i cannot remember any more:
- after unlocking the bootloader i extracted the "boot.img" from CM13 and installed it by "fastboot flash boot boot.img"
- then i installed CM13 by the option "update" in CM_recovery
- after that i maybe tried to install TWRP (from the link above) by the ADB command: fastboot flash recovery twrp.img. Would that have worked?
- or i did it by the app "TWRP manager" which i have also installed
In any case until your answer in this topic i have not heard about the "boot" part having to be integrated into TWRP for it to work on the xperia.
Anyway: it works on my pollux_windy ok.
BTW: if it should some time in the future be necessary to install TWRP again on my "windy" would you have a link for a TWRP+boot.img for the "windy" as well?

"fastboot flash recovery" command will not work, because sony devices (at least besides the very latest ones) don't have separate recovery partition, as nexus and other manufacturers have. That's why recovery should be integrated with kernel in boot.img
TWRP manager could have possibly installed it for you properly, but to FOTA partition which is used to install OTA updates on stock Sony firmware.
On unlocked bootloader it is not in use and could store TWRP recovery permanently (as normal recovery partition).

Yes, i did. But in your tutorial i do not mention anything about the sort of recovery it needs to wor properly: recovery inkluding the kernel. Did you read the hints by Rootk1t above in this topic?
Sony doesn't have a Recovery partition.
Hence you need a FOTAkernel compatible recovery (latest TWRP 3.x are) (hack that takes the Sony partition reserved for over the air updates, and turns it into a persistent recovery partition).
This guide : http://forum.xda-developers.com/xperia-s/general/twrp-recovery-to-fota-partition-guide-t3258821 looks good but read carefully.
Why don't you try to step back to my guide. Back to the recovery flash.
Fastboot flash temporary TWRP, enter TWRP, format partitions to F2FS, wipe data and then flash RESURECTION REMIX 5.7.4 + Black kernel for pollux + Gapps ?
I will update my tutorial this weekend to explain better.
Keep in touch
@Djibe: just take a look in this topic above, posting #4. This is a file including TWRP + kernel. Only this one i was able to successfully instal by the command:
fastboot flash boot twrp.img
The TWRP that you link in your guide does not work because it does not include the kernel.
You should have pointed it out better to be understandable better by beginners like me
Otherwise: thanks a lot for your help and support anyway

Hey dude try this way out...
- Download Magisk manager apk. , patched recovery_ramdisk and TWRP for 9.1:
https://mega.nz/#!ohkgwSzb!xD32btG_3Sax-V7bn6xbWR5fH0crPrry06cCxusf5Hg
https://mega.nz/#!tkcTlATI!A8UJGPBGtxJbLcUOJoxCGJj5PFZXzCnjbb3OkwqKTP8
https://mega.nz/#!xkd2ibKY!JCLNMNKRI1e0FI1bJ4YI5Lr9Hdg9eo4A9kv0MhxgIdA
Copy TWRP and patched recovery_ramdisk to SD Card, install Magisk manager apk.
- Install TWRP over eRecovery: flash downloaded TWRP 9.1 from fastboot, boot in TWRP, select storage - SD Card, select "Install image". Find TWRP-9.1.img file , mark eRecovery and confirm. Reboot system.
- When the yellow unlocked phone warning appears, press and hold Volume Up , phone will boot into TWRP.
- Select Install image, find Recovery_ramdisk-patch.img , mark Recovery, confirm.
- Go back to the main TWRP's menu > Reboot > Reboot recovery. Phone will reboot via Recovery , but not into Recovery mode. Now every time you want to boot phone with root access must hold volume up and power at the beginning . if you boot phone normaly (not thro recovery comand) your phone will not be rooted!
Now you have a rooted phone with TWRP on board.
Ok thanks, isn't it possible to workaround the volume up stuff? How do I boot twrp after I finished? Vol+ and power button or vol+ and cable? To my understanding, this boots two different recoveries?? Why is it so complicated lol

Is your patched_ramdisk "universal" ? I meant will it work on phone with different cust (mine is c55, most have c432 and maybe with different emui version? Where did you get it?)
- it is just an alternative, the method with patched recovery_ramdisk and fastboot should also work. Maybe you're doing something wrong.
- It is complicated due to emui 9.1, the ramdisk partition no longer exists. As a workaround, Magisk will be installed to the recovery_ramdisk partition.
- AFAIK partitions Recovery and eRecovery are the same for all build numbers and regions (we are talking about ANE- models and EMUI 9.1), so it should work.
- "How do I boot twrp after I finished?" - read carefully please: " Reboot system. When the yellow unlocked phone warning appears, press and hold Volume Up , phone will boot into TWRP."
P.S.: I never try to convince anyone of anything, it's your choice .
If you do not understand something here, than the tutorial might not be suitable for you.
There are plenty of guides on how to do these things. GL!

I tried the following:
Booting into TWRP, getting recovery_ramdisk with dd, patching image with manager, boot into twrp, flash new recovery_ramdisk with dd, reboot.
Getting recovery_ramdisk from official update, patching etc.
Flashing official Magisk v21.1 with zip. The new image is flashed because the second time it will say "magisk patched image detected" (even if i reboot into twrp again), but still no root.
Sincerely I do not understand what I'm doing wrong. I know myself it should be easy.
I understand the tutorial (and thank you for it, you are a very kind person) I just don't understand why huawei made things so unnecesarely complicated. How does the phone boot without a ramdisk? Is "normal" ramdisk included in the kernel partition or in the recovery_ramdisk partition? Ok I get it, if there is no ramdisk the phone boots directly from the system on root partition, so magisk should mod that partition but it can't because it defeats the purpose of "systemless". Right?
There are plenty of guides, yeah, but everyone says the same thing (magisk zip or patched ramdisk) and people just say it works... but in my case it just... doesn't
Will try to follow your guide to the letter... Thank you again...
Ramdisk is included in the recovery_ramdisk, that's why Magisk will be installed to the recovery_ramdisk partition. Read carefully bro
Note: if you want use TWRP on rooted EMUI 9.1, you MUST install TWRP over eRecovery.

Hello all,
It's a long time that's i haven't post a thread here but i have a question.I have a Poco with MIUI Global 9.6 Stable (9.6.25.0) for ROM with a Android Version 8.1.0 OPM 171019.011 with root acces, unlocking bootloader and TWRP 3.3.0-0 installed.
I would upgrade my phone to something "newer" (A ROM with Android 12 if possible) and conserv the root access and my apps.
I have read that now ,we should have 3 files to do that (firmware,system and vendor) to make a wipe and install new ROM with TWRP.
So my question:
-Is it possible to upgrade Android 8.1.0 to Android 12 witn a new ROM? (i have read something about kernel in Android12 but haven't understand all)
-Have i missed some steps or just download files,boot TWRP,wipe and install newer ROM+firmware and vendor appropriate is good?
-Which ROM do you recommend?
Thanks for the previous answers.

It's not possible to switch from stock ROM to custom without doing clean install. You will have to root again.
First update to latest Official Stock ROM, then take backup of your files to your PC or to SDCard (if you have one) , flash to latest Official TWRP and check my POCO F1 Ultimate Collection & Guides. You can find everything there. I have awarded recommended ROMs in my collection.
Feel free to ask if you have any question regarding the guides.
Thanks for the answer.I have begin to read your guides.
If i understand good,it's not possible to conserv my root,unlock bootloader and twrp when i upgrade to android 12? Automaticaly i should root again my phone and restore with titanium backup my files,contact,....?

Then you should update to latest version of MIUI via OTA if it's possible or via TWRP (you can use the stock recovery rom to do it via twrp). (You can also use my guides for clean install stock rom)
Then you should unlock your bootloader if it's not already unlocked.
Then flash latest Official TWRP.
Then flash latest firmware (not vendor) just to make sure you are on the latest. (You should be on latest firmware after updating to the latest MIUI version)
Then Wipe everything + format data according to my guides and flash the ROM you want. If you choose A12 Pixel Experience or crDroid keep in mind that these ROMs use their own recovery because these are encrypted by default ROMs and TWRP can't handle the decryption of A12 encrypted ROMs yet. So to make OTA updates and that stuff work correctly devs of these ROMs decide to use their own recovery which can handle the decryption of encrypted roms and as result to make OTA update work fine. Check the installation instructions of these roms in their threads. (Afterwards you can use adb sideload to flash stuff using these recoveries)
After that, flash Magisk since you want root.
Then you can restore titanium backup if you want.
OK i follow your instruction.Thanks
Hello retrial,
I have now updating my phone to MIUI Global 12.0.3 Stable with Android Version 10QKQ1.My phone is not yet rooted and now he is encrypted.The recovery is now Mi-Recovery 3.0
I have unlock again my bootloader.
Now to follow your instruction,i should flash the latest TWRP.
I have take TWRP-3.6.0_9-0-berylium in your guide.
I think i should do Fastboot Method because i'm now in Mi-Recovery?i'm right?
No problem with the encryption?
Thanks.
i have find this video.This is not the good phone but i think that the installation is the same:

Yes use Fastboot Method to flash TWRP. No problem with encryption.
After that follow my clean install custom rom guide to flash the ROM you want. Also please check the instructions in the threads of ROMs you want to flash. A12 crDroid and PE use their own recoveries.
Basically tell me which ROM you want to flash to help you exactly with steps.
Hello retrial,
i have a problem to install TWRP-3.6.0-9-0 on my pocophone.Everything working fine but in step 8 of your guide,i can't find my twrp.img that i have copied in 2 different case to test :
8. Boot into Recovery by typing in cmd: fastboot boot <recovery_filename>.img (The file may not be named identically to what stands in this command, so adjust accordingly and write the full path of it, check the example below).
This command will not flash permantly the recovery, it will just temporary boot into it and afterwards you will flash permantly the twrp.img you copied into your Internal Storage or SDcard in recovery partition.
For example: fastboot boot C:\Users\Retrial\Desktop\twrp-3.5.2_9-0-beryllium.img
Have you an idea to why i cannot find my twrp.img in the boot mode?

I have all the steps on my guide. Please read it carefully. It boots back to mi recovery because you haven't flash TWRP yet just booted into. After boot into TWRP u need to flash twrp in recovery section so it will stay after reboot.
Please read the steps.
Download portable Minimal ADB and Fastboot and latest Official TWRP recovery.
Open cmd from minimal adb and fastboot and write:
fastboot boot and the path you have TWRP.
Example:
Code:
fastboot boot C:\Users\Retrial\Desktop\twrp-3.6.0_9-0-beryllium.img
Then proceed with the rest steps in my guide. Connect ur device to pc while u are booted into TWRP and copy TWRP.img to your device. Then in TWRP press Install Image and select the twrp.img u just copied into ur device. Select recovery and done.
I have made a video to show you what happened (sorry for the bad quality and the moove) :
I think a video is easyest to understand my problem.For information my bootloader is unlock and usb debugging ok.

Hmm strange, probably of MIUI. Anyway since you are going to flash custom rom, when u flash twrp in recovery go back and select wipe and wipe everything (read my clean install guide), go back press format data type yes, and then reboot to TWRP.
EDIT: I just saw u rebooted to system. That's not what we want. Press reboot to recovery.
i reboot first to bootloader after have flash the twrp.img in recovery.That's only the second time that i reboot to system to use the normal mode of the phone and reboot after to recovery mode to show you that mi recovery is back.

The TWRP flashed correctly. You overlap it again by pressing reboot to recovery from MIUI updater.
Don't do that...do the combination to boot to TWRP after flashing it. Power+Volume Up.
And continue with clean install steps in my guide to flash custom rom.
In my guide I write nowhere to boot to MIUI and press from MIUI Updater reboot to recovery, please stick to my guide and you will be fine.
