Installed Cyanogen 13, bootloop and i can't get in recovery mode. - G4 Q&A, Help & Troubleshooting

Note : I have never posted on XDA before, when I'm posting this I'm stressed as hell so I searched quickly on the internet but nothing helped so
Here I go, I recently rooted (with twrp) my LG G4 and I installed Cyanogen 13 on it. (i followed this guide : /watch?v=P_9HasZKwWA)
Then I installed Flashfire and it told me I didn't have root access (which I had) and because I'm stupid I installed SuperSU which told me to do someting with the recovery mode, which the phone did. It flashed something with TWRP and now I'm stuck in Bootloop (the little blue droid) and I can't get in recovery mode with the Power+Downvolume technique.
I am desperate, please help me... My PC recognizes the phone (you know it makes this little noise) but doesn't show it...

I GOT IT!!!
You need to hardreset the phone (find on google) and then it's all good!

Probably you have lost recovery system.
The only way to get rid is fastboot mode.
Is phone booting in fastboot ? If bootlogo is coming then probably it will.
Google for it how to enter & flash image in fastboot mode.
Learn how to use ADB & Minimal Fastboot
As you will be doing first time,
1. do not flash all the partitions i.e. boot, rcovery, system, data, cache etc.
2. Download suitable TWRP version for your phone , Start your phone in fastboot and give a comand in adb "fastboot boot twrp.img" this will boot in to twrp mode & you can acess your phone. If this is sucessfull then,
2. First only flash recovery i.e. "fastboot flash recovery twrp.img" command only.
goto "en.miui.com/thread-307022-1-1.html" here is a complete guide but this is for xiomi phone, LG will have similer type of arrangement.
Flash TWRP in recovery partition i.e. "fastboot flash recovery TWRP.img" then enter into TWRP by rebooting and flash any ROM thru TWRP.

My OP3 won´t boot into recovery even after flashing stock image via fastboot

Hello everyone,
i think my OP3 is bricked, cuz after i wanted to install new custom ROM with TWRP it went south. When I swiped to install the ROM it showed, it´s corrupt so i wanted so i wanted to push some other .zip to the phone through adb, but no device showed after adb devices or fastboot devices in fastboot. So I tried restore phone from backup i had via TWRP and the phone just wouldnt boot. Oneplus logo showed for a few seconds then it disappears and phone goes dark. Have to hold start button for 10 sec for hard restart phone and then i can go only to fastboot (now it will show fastboot devices in command line). Recovery won´t boot. Tried flashing stock recovery, some versions of TWRP and still just OP logo and dark.
Thanks for every help.
I think for:
fastboot -w
fastboot flash recovery recovery_of_ur_choice.img
on flashboot mode obviously ^^
With that, u must have access to twrp

I killed my watch

1 week ago i bought in china the watch .i dont know Chinese and i was just there for business so i thought that when i will connect to my phone it will automatically change to English but that never happend . So i tried several threads in xda to understand how it is working and what can i do . And i followed the thread that says to flash another system img recovery and boot . So i first unlocked the bootloader and booted on it and i flash the images and tried to reboot to recovery but already the recovey option in the bootloader is missing i get only shutdown , reboot , reboot bootloader , so i thought that i haven't correct flash the recovery.img so i flash it again but still the same . I also tried twrp recoveries and other recoveries that i found in other threads but still the same i can only boot to bootloader and nothing else . Has any one had the same problem and fixed it ? And if not were can i find the stock chinese firmware to try to flash it maybe it will come back to life .. thanks in advance
Have you tried using adb and fastboot commands?
Ex::
adb reboot-bootloader (for bootloader)
adb push xxxxxxx.img or xxxxxxx.zip /sdcard/ (for transfer files to sdcard)
adb push recovery.img /sdcard/ (for transfer yours custom recovery - i recommend the latest 3.1.1.0 because the others have some bugs)
after that boot to recovery: fastboot boot recovery.img (personally i never tried to flash the recovery but just boot it, baut it works)
from recovery just install the files that you have transferred earlier to sdcard (oh, and prior that erase everything except internal memory, or that toot but you have to transfer your files again)
ex: install zip (i recommend negalite) after that install kernel (negalite too) and install performance or battery booster .
Oh, after kernel install, it will automatically reboot, so you have to repeat the process to install the booster.
Reboot.
p.s. - the reboot process take LOOONG, so wait patiently.
Hope i could help you.

If you want to enter the bootloader, to choose, where u want to reboot and you are stuck:
Hold the button on your watch...hold it, till you feel the first vibration after the restart at the HUAWEI-Logo. Then, press the button once again (Its just timing).
It should show you your bootloader and you can restart into recovery or wherever you want.
Hope I could help :highfive:

Can't boot in recovery anymore after flashing a recovery in recovery

Hello
I wanted to flash Orange Fox 9 on my redmi note 5 pro, i was on orange fox R10 (because impossible to do a simple factory reset on this recovery don't know why, the dev tried to help me but even him don't know why it don't work)
I flash it trough the recovery R10 (by flashing the recovery.img and check recovery partition in orangefox) , because in fastboot it say "anti rollback failed" but after that, my phone won't boot in recovery mode anymore.
Even if i use "fastboot boot recovery.img" it doesn't work, i tried this command with twrp (who work before but password issue) and the stock recovery miui. It won't start in recovery mode
So i tried the command "fastboot erase recovery" but it also doesn't work the "anti rollback failed" error show out.
The good news is i can still use my phone, but without recovery i can do nothing so i'm looking for a solution to recover the stock recovery of my phone
After all of that, i tried to flash twrp trough the app of the playstore, but it does nothing also. Its seems that my recovery part is corrupted and it can't be replaced by another. .
So what can i do with that, it's a pretty annoying issue..
Thanks in advance
Solution founded :
After i flashes orange fox 9, it was impossible to boot on third party recovery i think.
Because i tried one more time to boot on stock recovery and it work. But after I boot in my stock recovery i was not able to boot in my system
So I tried to go back on orangefox 10 butthere is big issue with the anti rollback and many errors in fastboot like (too many links) (file limit error). It's very hard to perform a simple fastboot because of that.
To bypass it, the phone need to be unplugged, I type the fastboot command (fastboot boot recovery.img) I press enter and fastboot show "waiting for device" and then I plug my phone.
90% of time it work. But I don't know if I let the phone plugged and I do it, it will show me an error.
Anyway, after I just format all partition on the phone then I flashed the stock rom and the phone reboot.
But impossible to factory reset in orange fox which was the original issue and don't Kno Ho to do it

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 Hard brick Poco f3 no recovery

Hello community, first of all I clarify that I am using the google translator.
As the title says, my poco f3 has a hard brick, I was trying to flash the miui global rom via fastboot(stock rom was global miui for turkey) but an error occurred in the process (the same as attached in the image), at that moment I got scared because the phone did not start the system.
The bootloader was obviously unlocked, I tried to recover with XiaoMitool but nothing, I couldn't flash super.img either in Xiaomiflash, then I decided to download its stock rom and redo the process but it failed.
Before all this I had tried to install TWRP or OrangeFox but none could be installed, I only got to the TWRP boot but the option to flash the current TWRP did not appear and it did not recognize the internal memory and the OTG with the zip. Right now it only shows the POCO logo and goes directly to fastboot mode.
I'd appreciate your help.
Edit: It does not have the recovery stock

try booting twrp via fastboot and then format data.
Obviously you'll lose your data, but it might give you access to your phone back.
Good morning.
Try to enter with quiet fastboot mode, both in twrp and orange fox, it's the same process. Put the phone in fastboot mode and then open minimal adb.
1. Put the fastboot devices command, the serial number of your mobile should appear on the command screen.
2. Put the command fastboot boot orangefox.img or twrp.img, take a good look at the file you have downloaded, to make the boot easy, it has to be an .img image and not a zip file.
3. If you can get into both fastboot and orangefox, please format the data.
4. Try to flash the miui stock rom with the same process where the error appeared, remember that this rom (it worked for me) has to be the rom for the poco f3 fastboot, since there are 2 versions (I think I have seen this) one which is fastboot and another which is not.
LUCK!

Hello, i had already tried to boot with twrp.img but without success, the good news is that I have already recovered it and the solution was as simple as taking the flash_all.bat from the rom and it could already be in any version of miui.
What I don't understand is why it hadn't worked with XiaoMitool and Xiaomiflash, and I still can't install TWRP because it doesn't recognize internal memory and OTG.
Anyway thanks for your help.

Glad you got it sorted, When installing a MIUI stock rom remember to put the Firm wear folder on your C: Drive and remove any spaces from title,
As for TWRP & Orangefox recoverry, i installed these in fast boot mode and use "Temporary Recovery" by downloading RUN_TWRP-Orange Fox FIXED.bat /unzipping/ and running the "RUN_TWRP-Orange Fox FIXED.bat File, once in temporary OF Recovery you can choose to make OF Recovery permanent by installing current version of OF from within OF, Check my post on the EVO-X Thread post 20,
you will also find my post regarding OTG issues,
--------------------------------------------------------------------------
OTG is no longer Now working with Orangefox recovery.
To overcome the OTG showing 0MB or .., remove the OTG adaptor,
reboot into OF Recovery, re-connect your OTG adaptor and
tap ☰ in the bottom right of the main screen to open the MENU,
open Mount, tap USB-STORAGE (wait 5 seconds) the (USB-STORAGE background will turn black), shortly after the check box will enabled, many thanks to Rafsf for the Workaround.
I hope this helps a bit
