A strange problem. I flashed 18.1 and it seems to work (I can boot into a minimal system) but now I can't get into TWRP Recovery even though I used it to flash 18.1 in the first place. The phone powers up fine but when I hold down Vol- and power, it does not boot into TWRP but boots into Lineagos. If I try ADB, then it sees the phone but it's offline and I've tried all the tricks to get it back online.
I also notice that when the android on his back is displayed, then Download Mode at the bottom is indicating Disabled.
Any ideas, or is it completely stuffed?

Hey there,
so I wanted to update LineageOS to the latest nightly (1st August) coming from an April nightly. I did it OTA, entered TWRP, installed the update and got stuck in TWRP, which is apparently a known issue with TWRP 3.0.2.0. But I didn't know that, and tried to fix it by installing a backup of CM 13 WITHOUT wiping data, because I did not want to lose my data. Stupid, I know.
I then found a fix to leave TWRP and tried booting into CM 13 but now I'm stuck in a bootloop. It shows the CM logo, then prepares apps, shows the logo, prepares apps, logo, and so on...
I can't enter Download mode or Recovery mode using the keys and adb/fastboot commands don't work while the phone is turned off or booting.
Any ideas what I can do?
Some more info:
It only bootloops when plugged into my pc. When it's unplugged (or plugged in to just power) it stays at "preparing to start". Sometimes it even leaves that screen but then the System UI keeps crashing leaving me with nothing to do but hard reboot. I still can't Recovery or Download mode tho. And whenever I plug it into my PC, it reboots
So you can't get into downloadmode with holding [Vol Up (+)] and plugin the cable into your pc at the same time?
[Edit]: Sorry, [Vol Up] is the right key.
So I got myself a cheap TF201 tablet and decided to put Android 7.1 on it using this guide. I followed the instructions completely and everything went perfectly well.
Had TWRP 3.2.3.0 installed, Android 7.1 installed and it was working great. Rebooted a few times, set up my Google account in Android, started installing a few usual apps such as Chrome, etc. when suddenly the Pad completely locked up. It then rebooted and went straight to the TWRP logo screen, sat there for 10-20 seconds then rebooted. And now that is all it does - ASUS screen comes up for a couple of seconds with "This device is unlocked" in the upper left, then tries to go into recovery but it reboots instead.
I cannot access fastboot mode at all - holding PWR + Vol DN does nothing. I can access APX mode and I can briefly use ADB while the TWRP is up.
I have backups of all blobs and I have nvflash installed - I got through the whole guide step by step without a single problem.
Any help would be hugely appreciated!
I got quite the same issue here, I also flashed 7.1.2 yesterday and installed some stuff. Then today I wanted to install Magisk to root it. After the installation (I can't remember that it was successful but I think it wasn't because there was no Magisk app to find) I wanted to boot another time to the recovery and went into a bootloop. When I'm trying to boot to TWRP it stucks at the teamwin logo. Sadly I have no cable here at the moment to maybe reflash the recovery or try some other stuff.
Hi everybody,
I tried to install Magisk 21.2 on my stock Oreo rom with Magisk 20.4 already installed. I've used the recommended method for installation in Magisk Manager, and I left the AVB/dm-verity option unchecked. It resulted in a bootloop.
Before updating I did a backup of the boot partition, so I could restore the previously working Magisk 20.4. Now I have two questions:
1) Is there something else I should do other than restoring the boot partition after a bootloop?
2) Is there a way to install the new Magisk or should I just dismiss the update notification?
Happened to me As well on my G6.
I had to reinstall the rom. good thing i had backup.
I've downloaded the zip file of Magisk 21.2 and flashed it with the rom after wiping almost everything, and even tried flashing a different rom with it (I'm using stock A9)., but it seems it resulted in a bootloop every time.
There is a new magisk 21.3 from yesterday, which i hope fixed those issues as i am not planning to go though that hassle again.
I tried the new 21.3, and still it causes bootloop, at least I'm glad I'm not the only one.

It happened to me, same setup as the OP and did the direct install method from Magisk Manager. My phone is stuck in bootloop at the triangle/! scrren and I can't access TWRP via the normal buttons manner. Also, can't get any ADB to detect the phone (I am using a new PC that probably never connected to this phone despite loading ADB, drivers, etc. - I am going to resurrect the previous PC to see if can connect).
May I ask how you restored the saved boot image? via TWRP restore?
I've rooted and played with many ROMs on various android devices, but I'm no expert and this one has me stumped.
Yes, I did a backup of the boot partition before flashing Magisk and then I restored using TWRP restore. It's not the first time that a new Magisk version causes bootloops on the G5, to I was prepared this time.
By the way, if you don't have a backup, you may try to flash the Magisk Uninstaller zip, and without rebooting, the old Magisk 20.4. In theory it should do the job.

Thanks, But how to access TWRP or flash the zip? I haven't found any technique to access recovery (Power+VolDn doesn't work, only allows Factory Reset screen). How to access Fastboot to use ADB (I assume that would be the technique)? I did manage to bring up some odd screen that had a two-line message about fastboot by, I believe, using Power+VolUp.
For clarification this is what I now have:
Phone off (remove battery). Insert battery. Press power button until brief vibrate (1-2 seconds). Release power button. Triangle with "!" displayed "Your device cannot be checked for corruption. Lock the bootloader. " screen displays for about 3 seconds, screen goes black a second or less. Back to the previous warning screen.
Press and hold Power button + Vol Dn acts just like the above, but if I press power + press/release/press/release... I can get the factory data reset (Yes or No(Exit) options) - I haven't accepted that.
I've tried connecting PC to the USB port and two things: as soon as I connect it, the phone powers on and does the looping again. My PC doesn't see the phone in Device Manager and ADB won't list it. I did (one time) manage to bring up the two-line fastboot message at the top of the screen.
BTW: when it first tries to power on, before the Lock the bootloader screen, there is a small, scrambled white area (text?) at the bottom of the screen.
I don't know when was the last time (if ever) I attached to the phone via USB (probably a few years ago when I initially installed TWRP). Haven't really done much other than upgrading TWRP (via TWRP), Magisk (via Magisk Manager), and the very occasional nandoid backup via TWRP (I have one from 3 months ago).
Any further assistance or info would be greatly appreciated.
To access TWRP, turn off the phone, then keep pressed Volume down+Power and once you see the LG logo release the power button and press it again. The phone should ask you if you want to reset everything: if you press yes and then confirm, you will:
1) Enter in TWRP, if you have TWRP installed, or
2) Erase the whole internal memory, if you don't have TWRP installed.
As you already have TWRP installed, it should be quite safe to go through the reset procedure, or at least that's what happens on my phone. If you don't want to take the risk, you can still use fastboot to boot a TWRP image you have on the pc, just write
Code:
fastboot boot <path_to_twrp.img_on_pc>/twrp.img
To do so, you first need to boot into fastboot: you can just turn off the phone and, keeping the Vol- pressed, connect the USB power cable to the phone. It will boot into fastboot.
One more method could be booting into download mode (Vol+ and connect the USB cable) and flashing an original firmware using LGUP, but that is way too much for a phone that already has both TWRP and fastboot accessible.

My phone never got past the bootloader screen (i.e. never got to the LG logo screen). When I booted into fastboot mode with the Vol+ button, I could issue commands like "fastboot devices" which would return that it saw my phone, but attempting to use fastboot to reload TWRP didn't work - some say the LG fastboot has been neutered.
Eventually, I had to indeed use LGUP/Uppercut and reload the stock Oreo and the phone came back up. BUT attempting to reboot into bootloader not only didn't come up in TWRP, but I got the little dead Android image. I ultimately had to downgrade to OEM nougat, jump through a few hoops, and finally got TWRP installed. Then it was just a matter of restoring a backup or reflashing a newer ROM (I ended up loading lineage 16, no gapps, with microg etc.).
Somehow the magisk upgrade really trashed my recovery partition somehow (??). I've always made sure to have at least a couple of TWRP backups, but this time I was screwed royally when I couldn't access recovery. I forgot what an ordeal it was to get TWRP & root on this phone originally.
Thanks for your help.
Hi Community,
I read some posts how to fix my Problem, but i cant go to a service Point.
So I was using the Evolution X for a long Time (Installed with TWRP 3.1.0).
And now i wanted to change to the Nusantara Project (Vanilla), I did a clean Flash, everything worked i could access the System.
Than i had problems installing Play Store, so i rebooted into Recovery via the System. But now im Stuck in the Loop.
Can i Somehow connect my Phone to the PC and Reset?
Can someone tell me if i Hard/soft bricked my phone ?
Just a little advice, would be really appreciated.
Thanks a lot
Go to TWRP, wipe system, cache, data and dalvik. Now flash nusantra and whichever GApps are recommended for it (if there are no recommendations then use OpenGApps, make sure the architecture is correct). Now wipe dalvik and restart. Sometimes, certain roms begin to bootloop if you boot into the rom first, then try to install gapps later.
If you still have issues, just reflash the stock rom.
I cant access the TWRP anymore, im just stuck on the Bootloader, no matter how i turn on The Phone (Volume Up + Power ON ), (Volume Down + Power), (All 3 Buttons)
Nothing works anymore i dont understand ....
Im searching the net but i cant go to fastboot or something else, its just keeps on rebooting ...
So it's bootlooping, but you cant access recovery?
When the screen turns off, press the key combo and it should go to recovery.
Your best bet is to take it to a service centre, but if that really isn't possible for you, then wait for its battery to drain completely, then when you plug in the charger, instead of turning the phone on, press the key combo to enter the recovery. From there, wipe and flash some other OS.
I've also heard that certain versions of TWRP don't support some roms, leading to a bootloop. In that case, you'll have to use orangefox recovery to flash the rom (orangefox is flashable via twrp)
Yes its Bootlooping.
When i turn it on, on the Left Corner "Recovery Mode" blinks for one second. Than the usual Text appears:
"Orange State
Your Device has been unlocked and cant be trusted
Your Device will boot in 5 Seconds".
So after a couple of seconds (around 10-20 sec)
It turns off and immediately on again. I Just can turn it OFF when i hold all 3 Buttons.
Than i try starting it with Volume up + Power / Volume down + Power, But i cant access Recovery or TWRP.
So i should wait til the battery gets low and try it again ?
Like i said, my custom Rom (Evolutionx) and TWRP just worked fine. I dont know man ...
Well since your bootloader is unlocked, try flashing the stock rom again. Look for a tutorial and follow it.
Hi I managed to unbrick my device with this guide, and im back on a stock rom
Unbrick
i ran following commands to get to my custom rom:
I run adb reboot bootloader,
add executed following commands.
(Pitch Black recovery 3.1)
- adb reboot bootloader
- fastboot flash recovery recovery.img
-fasboot reboot recovery
It just hang up and booted after a while into the normal system.
But im not able to get to the recovery menu ?
When I restart and hold Volume up + Power, i go in a loop and the phone keeps restarting over and over again.
what have i Fu**ed up ?
Do i need another recovery tool ?
sorry guys, i appreciate your help a lot tho !
EDIT: Is my bootloader unlocked ?
I can access via "adb reboot bootloader" the phone
and on the blackscreen on the phone it is written:
oppo verfiy pass
fastboot_unlock_verify ok
Update:
So i tried some Stuff and i got Red State. No Problem i Unbricked it once again and now im on Stock Android 10.
Now im Trying to enable the bootloader again.
I downloaded the In Depth Test_Realme_6.apk but i keep getting the Error that i should update the system.
So should i update the system ?
I cant find a CURRENT Tutorial to make this work, please help...
If you cant find a tutorial for your version, why not downgrade back to a previous one if possible.
Sooooo a while back I really screwed up my OnePlus N20 5G (CPH2459). Currently, it will turn on, but after one try at the OnePlus logo it reboots to recovery. I can get it to go into fastboot mode but ADB doesn't detect it.
It was rooted using Magisk.
My first question is, does anyone have the full firmware for CPH2459?
And...
What can I do to get ADB to recognize the phone so I can flash the firmware?
Ok yes I'm using the red cable
I was using the driver's from the website.
I was trying to use rom2box.
I tried.
ADB won't recognize it because of the problem if not booting past the logo and going straight into recovery. Fastboot didn't recognize in that mode either.
Everything leads back to my issue of needing firmware for the CPH2459 model.
I figure if I just flash stock it'll be fine, right? But I can't find full stock...
I know adb and fastboot are different. But I'm in fastboot mode right now and I can't get the phone to show up. Also when I hold only the power button, it vibrates, shows the OnePlus logo restarts on its own, vibrates again, shows the OnePlus logo again, then loads ColorOS Recovery
