Not able to go into recovery mode

Hi
I have a H815 Singapore version. Not rooted. No matter what method I tried that I found online it will just boot regularly and not able to go into recovery mode.
Anyone has any idea?

Although i have an international i had the same problem.
What i did was boot into fastboot. Then run the command "fastboot boot *whatever your recovery is called*
then copy your recovery into your internal storage. Once you have boot into twrp install the twrp image by clicking on the image button on the bottom right.

Any help on this? Plz...
Thank you!

1. fastboot boot recovery your_recovery_image.img
2. flash twrp image from booted twrp

Or fastboot flash recovery twrp.img

No ! This doesnt work. Read the official twrp xda thread.

Hi!
I tried all that, flashed all TWRP versions, all available versions of european rom for LG G4 H815, nothibg... the damn thing just don't work on my phone

Have you followed the right steps?
First use fastboot boot twrp.img (boot not flash)
Then within twrp copy the twrp image from your pc by adb or mtp then use the button to flash an image and then choose the copied twrp to flash to recovery

Now I think you got me... I followed the tutorial how to install twrp but, in the beggining I was having problems with the drivers. Win10 was changing them on every command, and after so much time (I went to sleep at 5 AM ) trying everything that it could work, maybe I just mess on that step....
Thanks for your help. As soon as I have time again, I'll check that step.

Thank you very much @steadfasterX !!!
It works
I followed this tutorial: http://www.technobuzz.net/install-twrp-recovery-on-lg-g4/
Thats why I got mistaken... Thanks once again

TWRP not persistent

Hi guys,
I've just updated to newest OOS firmware wich is 5.1.2 and I'm facing a weird problem.
Every time I flash codeworks TWRP and reboot to system, the next time i try to boot to recovery it boots to the original recovery.
It's like when I flash TWRP it doesn't remain persistent. When i flash it through fastboot and straightly boot from fastboot to recoverry I succeed to get in TWRP but as soon as I reboot to system and try to boot to recovery I reach the original OnePlus recovery.
Is anyone facing the same problem ?
And also do you have any idea about what i could do to solve this problem ?
Thanks in advance for your answers !

If you don't have root or custom kernel its normal, plus you should use blu spark's twrp, its newer and more reliable.

Indeed, I just needed to flash magisk to get it persistent. I'll try blu spark's one as you suggested.
Thank you very much for your answer !
Cheers !

Nothing to do with recoveries or kernel. After you do the fastboot flash recovery TWRP in fastboot, do this: "fastboot boot TWRP". I believe that's the right command. Basically after you flash it, manually boot to recovery through fastboot one time. After that it'll work from inside the phone or with the button combination with the phone off.

Jesus people are lazy these days.
First off there are official twrp versions for a reason!
Download the latest version: https://dl.twrp.me/dumpling/
Reboot into flash boot with the following command from your rom: adb reboot bootloader
With phone in fastboot mode: fastboot flash recovery 'twrp.img'
(You don't need to type out the entire file path you can just drag the file into the terminal and it'll insert the file location)
The reason you're not getting back into that recovery is because you're not booting into the recovery before you reboot into your ROM.
There is an option to boot straight into the recovery from the fastboot mode

Actually not that lazy because I used to do what you mentionned.
The thing is that a flash of Magik is needed to patch twrp. That's the step I forgot in the procedure and explained here.
So before being unpleasant, please know what you're talking about...
Cheers !

how to flash recovery img ?

Hello, on any custom roms we see recovery as img, so whats the ultimate good process to actually flash it?
img to tar bootloop
any other recovery bootloop
only one thats working is "twrp-z3s-3.5.0_10-A11_6+vbmeta_DUB5" BUT i have x1s, so pain to flash some rom.
Im currently on beyond rom 3.1, because i cant flash anything else.
Any help here?

Try flashing vbmeta.img after flashing recovery

like download mode -> recovery, then download mode again and only vbmeta?
didnt try that, ill try it right away
edit:
1) download mode -> AP EXYNOS-G98X-LINEAGE-RECOVERY-20200709
2) booted up rom
3) turned off -> download mode -> USERDATA vbmeta.tar from beyond rom
4) bootloop, up button and power same thing

i dont know if i should try stock and then go for root again or what exactly do.. i dont want to lose any data now. It got really complicated, since i go from root apk clockworkmod era.
maybe magisk is the issue? since i have it installed

Go to fastboot
Flash recovery
Flash vbmeta
Reboot
If fastboot doesn't like extensions of your images, change them to .img

how can i get to that? on TWRP if i do reboot -> fastboot, im still in TWRP and "fastboot devices" shows completely nothing (not even list of devices or whatever)
when i go to bootloader mode from magisk i just see "entering fastboot mode.." and thats about it, no fastboot commands work

Move vbmeta.img to your phone and go to Install section. Install it and reboot.
Also, TWRP offers an option to reboot to bootloader. You can try it too

well, i flashed lineage recovery img and then vbmeta, phone booted up, but got probably original recovery. its really frustrating. Do you have any valid and working "tutorial" to get the recovery working ?

i just need recovery thats x1s, so it should be probably lineage recovery, but cant install it. Im starting to hate these new phones.

I'm sorry, I don't have any specific tutorial, but in general:
adb reboot-fastboot
fastboot flash recovery recovery.img
fastboot flash vbmeta vbmeta.img
fastboot reboot-recovery
If this doesn't work, search for your specific device on XDA. You shouldn't hate new phones, you should hate people who sell them, because they make everything hard so you won't switch from their software, which spies on you.

tried TWRP that works, installed as img lineage-18.1-20210224-recovery-x1s.img and now it suddenly worked. Thank you for help, after 6 hours =)

Question installing custom recovery when device has AOSP recovery

So I installed a A13 AOSP rom (Evolution x) via orangefox and when I rebooted to recovery orangfox was gone and now I'm on AOSP recovery. I tried to "fastboot boot" TWRP but the phone restarts on black screen for several seconds then restarts again to system. and when I enter fastboot thro AOSP recovery and try to boot TWRP it just fails (says unrecognized command boot). how can I flash custom recovery? i was thinking of trying sideload but with fastboot not working properly, I dont want guessing and rather ask someone with more knowledge with AOSP recovery and what could be causing fastboot not working properly
PS/ AOSP recovery is not detecting otg, and when choosing apply updates from internal storage it says it cant mount /data

It is because flashing rom also flash the recovery packed along with the rom, and it will replace your old recovery. To prevent it you need to also tick on the reflash ofox option when you flash a rom, which is too late in your case.
So, if you want to reflash ofox recovery, download and extract the zip file, locate the recovery.img in the extracted folder, reboot to bootloader and issue this command:
Code:
fastboot boot /path/to/recovery.img
then reboot to recovery with the command:
Code:
fastboot reboot recovery
and your device will temporarily boot into ofox recovery
The last step is to flash the recovery to ramdisk to make it permanently, you can find this option in ofox settings.

Thank you mf this worked! Booting twrp through fastbood just gave me black screen so I didnt think that booting Ofox would be any different but it actually booted Ofox recovery and I flashed it no problem. If anyone's going to attempt this make sure to backup your data before cause you'll need to format data
