LG G4: TWRP Recovery not working

Dear folks,
today I ran into a problem while trying to root my new LG G4 (H815).
It seems I succesfully unlocked my bootloader since it writes "BOOTLOADER STATUS: UNLOCKED" at every startup.
Now I tried to install TWRP recovery; I downloaded the newest version for my device from the official TWRP website.
I used the following command:
Code:
fastboot flash recovery twrp.img
I got the following output:
Code:
target reported max download size of 536870912 bytes
sending 'recovery' (31620 KB)...
OKAY [ 0.923s]
writing 'recovery'...
OKAY [ 0.303s]
finished. total time: 1.226s
Then I left fastboot via
Code:
fastboot reboot
.
But when I try to boot into recovery mode via
Code:
adb reboot recovery
I just get a picture of a broken android figure with a red triangle over its chest.
When I use the hardware key combinations and then answer "YES" it simply does a default factory reset.
I'm using elementaryOS 0.3 (based on Ubuntu Linux). I already tried different ways (with or without sudo, using the adb version which comes with the full Android SDK or the version featured in the Ubuntu repositories).
Nothing seems to work...
I hope I described my problem right and you can help me.
Thanks for all replys and greetings from Germany.
EDIT:
I now got into recovery using
Code:
fastboot boot twrp.img
.
From there I installed stock-20a-rooted.zip. That seemed to work. But when I boot the phone normally it just shows me the LG logo forever and doesn't boot into normal os. Only removing the battery gets it off again. Factory reset doesn't help either.

I would suggest to put a copy of the TWRP recovery to your sd card. Then simply boot into the recovery via the command: "fastboot boot twrp.img" and then flash the copy of the recovery from sd card permanently via the so far only booted but not permanently flashed recovery...good luck!

I did that but now I get a bootloop while starting the normal os. Factory reset doesn't help.

Update: When I connect my device with my PC while the bootloop is active, sometimes a Window pops up on my desktop asking for my PIN to unlock it. When I enter it nothing happens.

Ouch...corrupt twrp.img file?
---------- Post added at 12:49 PM ---------- Previous post was at 12:42 PM ----------
So maybe its best to start all over again...get into download mode via holding volume up and Power on. Then install original kdz via LGUP tool. Maybe you have a look at the german Android Hilfe forum, there are also the kdz files for download. Good luck!

Maybe... While in TWRP it looked like always...
EDIT:
Yes, I'm just downloading the KDZ files... Gonna flash it today. However, Thanks for your support!

I just succesfully installed autoroot kernel, flashing kdz was the solution. However, I still can't write TWRP into recovery partition, but at least I got what I wanted.
Thanks for your support!

you can write twrp by using twrp manager from playstore(2.8.7.0) then when you're IN recovery flash 3.0.0.0 (download from official twrp site or from orginal android development of LG G4) or use in adb fastboot boot (recovery).img

HELP!

Hi everybody. I'm a newbie in root, xda and forums in general, so please don't shoot me and help me if you can..
I rooted my lg g4 te first time thanks xda, but after having installed nougat via twrp, root is missing in any check, and twrp can be installed but not launched in fastboot. I tried EVERY guide i found in xda, but that famous command "fastboot boot something.img" is still not working... any idea?
Thanks

Oneplus 3 Boot Loop

So I tried to flash another rom by flashing TWRP and unlocking the bootloader, which worked and I then had installed Freedom Os. Then I locked the Bootloader to get the Message away, but know when you charge it or turn it on it is in an boot loop which repeats the Oneplus Logo what you normally see, but very short and after that it bobrates turns the screen off and it atart again. Or I can go into fastboot mode, but when I try to go into the recovery, it goes into the Boot Loop again. Is there a way to get the Original OS back? Ive already dopwnloaded it but I cant get in on there. Can you tell me how to fix it on my own?

[GUIDE] Mega Unbrick Guide for A Hard Bricked OnePlus 3 > METHOD 1

If you can access fastboot mode, connect the phone to a PC, then go to ADB and erase recovery using the command " fastboot erase recovery" and install TWRP 3.0.4-1 using the command " <fastboot flash recovery <recovery.zip/img> again.
Once you do that, boot into TWRP, go to wipe and wipe everything. Once you do that, transfer the stock OOS into the internal memory using copy-paste , then go to install , select the transferred file to install the OS or else go to advance setting in TWRP and select adb sideload and use the command "adb sideload <filename.zip>".
This should install the OS on the phone.
If you want to go complete stock, then you also need to install the stock recovery. Search the forum to get the relevent files or else you can download it from the OnePlus website and later on update to latest OS via OTA.
NEVER EVER LOCK THE BOOTLOADER , IF YOU'RE USING ANY ROM OTHER THAN STOCK OS AND STOCK RECOVERY

Connect your phone to the PC and then navigate to installed folder, right click holding SHIFT key and select "Open command window here"
Inside command window type
adb devices
If all the drivers are installed properly, you should see you're device ID here.
then type
adb reboot bootloader
your phone will enter fastboot mode.
then type
fastboot devices
again you should see you're device ID here.
then follow the instruction , i've given earlier.

So i've downloaded the software, installed the driver and typed in cmd adb devices "adb devices List of devices attached" is returned, so it seems like there is going something wrong. Is it because the Driver is installed wrong or because "target reported max download size of 440401920 bytes
sending 'recovery' (22605 KB)...
OKAY [ 0.528s]
writing 'recovery'...
FAILED (remote: Partition flashing is not allowed)
finished. total time: 0.551s"
This is returned when trying to flash. Do I have to be in fastboot mode or something else to be able to follow your instructions? In Fast Boot is written that the Device State is locked and Secure Boot is enabled. I messaged Oneplus and hope they have a solution which can just unlock the Bootloader when being in fastboot mode, so everything is fine again. I hope you can help me, but I still wanna say thank your for now

Thank you, but it dont works because i forgot to re-enable the oem modification and usb debugging in freedom os, maybe there is an option to do this without having this enabled but I didnt found it. So I wait for a helpful answer from somebody here or from Oneplus, I consider sending my smartphone to oneplus to let them repair it if I cant do it. Just saying that modding an S3, Asus transformer pad and nvidia shield is way easier.

Yeah I'm sorry I can't help you in your case. I'm just stating the fact. Sorry if I offended you.

Shouldn't it still be possible to reflash the properly signed official updates? TBH I never had such a problem and thus never had to cope with it. Same with recovery: http://oxygenos.oneplus.net.s3.amazonaws.com/recovery_op3.img Try flashing this one with fastboot. It's the official one. By flashing this one you might fix your stuff over adb sideloading the official full update zips.

Try the unbrick guide provided in the 2nd post to your query. It should definitely help. Better contact OnePlus tech2 support and they'll flash your phone for you. They're really helpful.

The MSM Software disconnects the smartphone while the process works

U cannot flash in adb while the bootloader is locked, u can not unlock the bootloader unless u can access ur OS, I am not sure y people was trying to get u to flash via fastboot the answer was provided to u in the 2nd post

^^^ This!
It's pretty much obvious fastboot flash will not work with a locked bootloader.
It's pretty obvious unlocking the bootloader will not work, while one can not access the OS.
Unbrick tool is the only option to bring it back to life, or sending it for RMA. If unbrick tool fails, try using different drivers and make sure it is connected with the stock cable (I've only tried with a Nilkin cable besides the stock one, which always failed at different stages during the process).
Not even sure drivers must be installed manually, I've never done that myself on Windows 10, as they were automatically installed (3 different's PC's, both on x86 and x64).

Which version of stock firmware did you last have? If it was 4.0.1 or earlier, then you can use
Code:
fastboot oem 4F500301
to issue a flash command even without unlocking the bootloader. If you are on that, then use that command and flash stock recovery and then flash stock zip.

[SOLVED] Could not install TWRP

Hi,
I want to enable dualsim on my singlesim device and for that the TWRP has to be installed. After checking many threads, which less or more describe the same steps, I managed to unlock the bootloader and downloaded an "unofficial" twrp image for the Moto Z Play. But on the last step while trying to flash it I got the error "Image not signed or corrupt" and the image is not installed. Here is the output by flashing:
Code:
D:\Programs\Minimal ADB and Fastboot>fastboot.exe flash recovery twrp-3.1.1-0-addison.img
(bootloader) slot-count: not found
(bootloader) slot-suffixes: not found

Is there a way to avoid this error ?

Use: "fastboot flash recovery twrp.img" no quotes. I change the filename to just "twrp.img" less chance of typing something wrong.
and no the .exe you did.

I think it is flashed. After flashing the twrp via fastboot and u see that error then just ignore it, instead directly boot your phone in recovery mode using the volume buttons and look for the word "recovery" then press on power button then it booted there.

which were downloaded from the url: https://www.androidfilehost.com/?w=files&flid=126925
The result is the same by all of them.
Just to be sure, the image should be copied within the "ADB/Fastboot" folder on my PC and not on the device storage/SD card, isn't it ?

I wanted twrp just to create a backup and configure my device to support dualsim. Therefore and as mentioned in a previous post, TWRP is installed only momentarly and after a reboot it would be overwritten.
My OS is the Moto Android 7.0.
What is the issue that you have now ?

As I told earlier I am not able to install twrp due to which I am not able to install custom rom. I tried many times to install twrp, everytime it showed "image is not found" as you guys said I tried going recovery but again it shows you already unlocked boot loader, your device can't be trusted then says " your device will reboot in 5 seconds" this is what my issue is.

It makes no sense then to flash it. Why don't you just use
fastboot boot twrp.img
when you want to start it? Then no flash will be involved, and twrp will be just booted for this single usage. You can repeat this whenever you need it.

trying to flash twrp?

I'm attempting to flash the initial image via fastboot to get into twrp so I can flash it and root but when I do it I get an error saying FAILED (remote: partition [recovery] doesn't exist) also when i try to swap slots to b with the -set-active= b command it says waiting for device and nothing happens... even if i unplug and replug the phone in and hear the sound it makes when its connected the bootloader is unlocked and im currently running 7.1.2 also when i try to switch firmwares it only flashes to one

You dont flash the initial .img file. You boot to it after copying the twrp zip to your phone.
Fastboot boot TWRPfilename.img
Using the real filename of course.
Then in TWRP you install the zip.

Unable to Install any TWRP Image on my Nokia 6.1 (2018) - Getting Stuck on Splash Screen

Hi Team,
I have an spare Nokia 6.1 (2018) smartphone (Model # - TA -1089)) at my home which I wasn't using since 2-3 years.
Today, I got hands on it, and tried to use it for my development needs.
To begin with, I unlocked its boot-loader using this guide to unlock Nokia 6.1 (2018)
and within "Developer Options", I can see that the "OEM Unlocking" option reads - "Bootloader is already unlocked."
Now, as a next step, I am trying to install TWRP recovery, but nothing seems to be working. No matter which image I try, I get stuck on the TWRP splash screen.
I have tried TWRP Images from the following websites and many more:
TWRP.me
Get Droid Tips - Here when I click on the "Download" option, I get redirected to the "TWRP.me" website only, whose images are not working.
In addition, I have ensured that "ADB and Fastboot" + "Nokia USB Drivers" & other contingencies are properly installed on my system & are not the underlying issue.
I tried running the code
Code:
fastboot flash recovery twrp.img
and my phone got stuck on the TWRP splash screen. Ultimately, I had to use OSA tool and flash the STOCK ROM to get my device working again.
Many websites suggested to simply boot the TWRP and so I used this command:
Code:
fastboot boot twrp.img
in the "Download" mode and then again, nothing happened and I got stuck on the TWRP splash screen.
Note: The only difference between above two commands being - my stock recovery worked fine after executing the 2nd command, and I could boot into my device without much trouble.
Here's my Device Overview:
Device Name - Nokia 6.1
Model & hardware = TA-1089
OS version - Android 10
Security Patch Level - May 1, 2020
Build Number - 00WW_4_15c
Can someone now please suggest where I could be going wrong?
What's my goal:
Root Nokia 6.1 & to be able to install Custom ROM's on Nokia 6.1 and use that device for development purposes
and in case anything goes wrong,
Flash the STOCK ROM again using OSA Tool and bring the device back to its current state.

Hi @White_devil_04200
Thank you for redirecting me to this Telegram channel.
However, let me share that - On the channel, I found "twrp-3.3.1-1-PL2.img" listed as the TWRP image that works.
The conflict is that - I downloaded this version only from multiple sites & after flashing it, got stuck on TWRP splash screen. I had to use OSA tool to reflash Android OS & restore the stock recovery.
And, when I ran the code -
Code:
fastboot boot twrp.img
, then also I got stuck on the splash screen, but was able to reboot into the OS successfully.
Note: Also, I tried switching the slots too (from 'a' to 'b' or vice versa') but then also, nothing worked for me.
I hope you get my problem, and would now assist me accordingly.

this is how i use twrp on nokia 6 2018 (since i unlocked it):
1. connect my phone with download mode to my pc:
2. run 2 code lines:
fastboot flash recovery twrp.img
fastboot boot twrp.img
3. and done.
The only disadvantage of this way is that every time I go to twrp, I have to run those 2 code lines with my pc. Still, it worked (at least for me).
You can try my twrp version.

Thanks @Bảo Dora for sharing your TWRP file and for the instructions.
I was finally able to boot into TWRP (used another file, of course), and then successfully get "root" access on my device.
Also, I read that if you execute the command:
fastboot flash recovery twrp.img
Click to expand...
Click to collapse
you shall permanently install TWRP on your device, which may or may not be the first preference of many users.
Having said that, am glad that it worked out for you. However, I still prefer to use just the "boot" command to avoid changing my stock recovery.
Thanks for your help again.
Cheers,
Manu

For potential readers of this thread, I would like to explain one thing here.
"fastboot flash recovery twrp.img" does NOT change your stock recovery on Nokia 6.1. Because this phone has "A/B system updates" and due to that the recovery RAM disk is now contained in the boot.img file. So Nokia 6.1 has not recovery partition so if you execute the "fastboot flash recovery twrp.img" command it only shows an error message and nothing is changed on your device.
Common issue on Nokia 6.1 is that when you execute only this one command "fastboot boot twrp.img" then it stucks on androidone logo.
But for some special reason, if you execute "fastboot flash recovery twrp.img" and then "fastboot boot twrp.img" it successfully boots into TWRP recovery.
Really there is nothing to worry about. This procedure is safe and really works.

Thanks @Bảo Dora for sharing your TWRP file and for the instructions.
I was finally able to boot into TWRP (used another file, of course), and then successfully get "root" access on my device.
Also, I read that if you execute the command:
you shall permanently install TWRP on your device, which may or may not be the first preference of many users.
Having said that, am glad that it worked out for you. However, I still prefer to use just the "boot" command to avoid changing my stock recovery.
Thanks for your help again.
Cheers,
Manu

Let me try and find that file link again bro. It's been time I performed the root process, so I will have to search for it.
Will share it with you at the earliest.
Till then, stay calm and be safe.

this is how i use twrp on nokia 6 2018 (since i unlocked it):
1. connect my phone with download mode to my pc:
2. run 2 code lines:
fastboot flash recovery twrp.img
fastboot boot twrp.img
3. and done.
The only disadvantage of this way is that every time I go to twrp, I have to run those 2 code lines with my pc. Still, it worked (at least for me).
You can try my twrp version.

Hello,
i have nearly the same problem atm.
I successfully unlocked the device.
When i do to 'fastboot boot twrp.img' in 8 of 10 cases it stucks on Android One screen but sometimes it stucks at twrp boot screen.
I have tried multible twrp versions for Nokia 6.1 PL2.
I also tried 'fastboot flash recovery twrp.img' but here comes a adb error that says:
Sending 'recovery' (38592 KB) OKAY [ 1.064s]
Writing 'recovery' FAILED (remote: '(recovery_a) No such partition')
fastboot: error: Command failed
On Galaxy S6 this works fine for installing permanently but here i event cant boot into twrb.
Any advices pls?
