EDIT: finally got it working

1- boot just the oldest recovery image of twrp 2.6.0 using: fastboot.exe boot twrp2.6.0.img (or whatever you're calling it)

2- be sure to have the SuperSU on your phone because you'll need to flash it, have the latest twrp.img on your phone too

3- flash SuperSU

4- go to install and select image

5- flash the twrp.img

6- enjoy and thank me later

Please help. I rooted my phone then I flashifyed TPRW 2.8.7 from t-mobile subforum. After I booted into TWRP and after a back up, I am not able to do a system reboot to back to Android OS. I tried all the reboot options but I keep going back to TWRP. I also tried restoring and still no success. Is there anyway if I could flash factory t-mobile image and lock the bootloader again? Or any other suggestions?

Edit: I re-flashed the factory image. Everything is back to normal. I will have to do everything again.

It would probably be a breeze if the bootloader was unlocked for that model. Sadly, it isn't, so until LG gives the go-ahead, there's nothing to be done.

[MENTION=912474]Dees_Troy[/MENTION] : quick friendly suggestion - would the title of the topic better be changed to mention version 2.8.7.0? In fact I started off with 2.8.6.0 but I was unable to restore nandroid backup with that version. When I use TWRP manager from the play store to flash recovery it nicely presents me with 2.8.7.0 which does everything right. (altough i have to mention that TWRP manager gives me an "unsuccessful flash" message after flash everytime, but when rebooting into recovery it's working anyhow). I have unlocked bootloader on H815 EUR model of course.
[G4 Original Android Development] pen²:
Is 2.8.7.0 able to split backups? I somehow lost exfat support and with a fat formatted sd, almost everything works - but twrp backups fail for the 4gb limit
[G4 Original Android Development] AfterForever666:
Just checked my backup files with total commander. My backup (all partitions) has a total size of around 8GB and the data partition is nicely cut up in slices of 1.4GB. So, I think that's good news for you.

Thanks for your reply, I already found that article, but I was wondering what a "read only mode" has to do with a backup option? Are you implying that, in order to later restore a clean state, one has to backup a "system image" first? (while a backup of system, boot, data would not suffice?)
[G4 Original Android Development] El Presidente81:
It's been a while since I've unlocked a bootloader and flashed anything so can I confirm this is still the way to go?

1. Unlock the bootloader (obviously)

2. Using ADB, enter "adb reboot bootloader"

3. Whilst in the bootloader, use the command "fastboot flash recovery twrp.img"

4. Once flashed, boot back in to the OS, then using ADB, type "adb reboot recovery"

5. Flash the SuperSU.zip from here: https://download.chainfire.eu/696/SuperSU/UPDATE-SuperSU-v2.46.zip

6. Reboot

7. Install SuperSU & TWRP Manager from the Play store

8. Success.

Sorry for asking something potentially stupid, but I'd rather ask a stupid question before I mess around, than deal with a balls up afterwards.
[G4 Original Android Development] 12890:
Is recovery also works on h815t?
[G4 Original Android Development] Jackering:
That is correct, when you boot TWRP though just press reboot and it'll detect root isn't installed and ask if you want it to install root for you, saves step 5+

[G4 Original Android Development] marcadam:
No it's not possible, you definitely need an unlocked boot loader to install a recovery.

[G4 Original Android Development] hauhauhau7:
Hello, sorry if it is a stupid question, i have the H815 international version and in the Developer options i have the "Enable OEM unlock" option, is this the same thing as unlocking the bootloader via the official LG unlock tool? i know that it will void my warranty if i unlock it via LG unlock tool, i want to know if i can restore the phone exactly how it came the first time i opened the box.

Thank you.
[G4 Original Android Development] nitrous²:
No. Simply and only activating this option will not unlock your bootloader.

When this option under Developer Options is enabled, you can unlock the bootloader using the official method. If it's not activated and you try to unlock, ADB will return an error and ask you to enable that option. If you enabled "Enable OEM unlock" you then have to visit LG's official page with instructions on how to do it. Once you unlock the bootloader it is permanent and can't be relocked unless someone finds a way to relock it (highly doubt it).

IMPORTANT

"Logs or it didn't happen" applies to all scenarios. If you encounter issues with TWRP on this device got to "Advanced" and hit "Copy Log To SdCard". Still in recovery, pull the log via ADB or mount the device's storage and transfer the log via USB to your PC or Mac and attach it to your post. This is because the famous "Crystall Ball" hasn't been built yet because the manufacturers Plumbus stocks are extremely depleted and reproduction is impossible due to the ban on Dinglebobs by the intergalactic trading comission.

So this is what I have been doing without any luck.

I am on marshmallow stock flashed through flashfire on a previously rooted lollipop.

I have an unlocked bootloader and am trying to install twrp.

1. Unlock the bootloader (done)

2. Using ADB, enter "adb reboot bootloader"

3. Whilst in the bootloader, use the command "fastboot flash recovery twrp.img"

4. Once flashed, boot back in to the OS, then using ADB, type "adb reboot recovery

Cant get into any recovery from here. Twrp or stock.

There is an android sign with a red triangle.

Reboot again and everything works perfect except recovery.

Just cant get twrp working.

Hey guys. I hope I'm in the right thread. I always get a dead android with a red triangle when I installed TWRP. I tried both methods via 'fastboot flash [twrp.img]' and booting the recovery on my phone via 'fastboot boot [twrp.img]' and then install it from within TWRP. To my desperation both methods didn't work and I'm stuck with this lousy dead android. Can anybody maybe give me a hint of what I'm doing wrong? :(

Any help would be highly appreciated
[G4 Original Android Development] Shadicbypass:
What variant of the g4 are you using and is the bootloader unlocked.
[G4 Original Android Development] Follow_and_Feel:
Bootloader is unlocked. And I have the international version of the LG g4 (H815). I tried to do it with the latest twrp and the oldest, to no avail. It just seems like I'm not installing it correctly. As I mentioned above I used two methods to install it - doesn't work either way. Help would be so nice. Regards
[G4 Original Android Development] josito_zgz:
I have exactly the same problem...:(
[G4 Original Android Development] navendugoyal:
happy to help. I had the same problem. this is what solved for me.

first install stock 5.1 using the new LGUP and the 5.1 kdz - if on marshmallow - else go to step 2.

Step 2 - Root it using the low effort root method.

Step 3 - Once rooted - very easy to install twrp. Download flashify and just flash the twrp img file.

Easy

this is what did it for me after fiddling with the same problem you have.

Let me know
[G4 Original Android Development] Follow_and_Feel:
Ok I will try this today, but if you upgrade back to marshmallow will the Recovery still be there?

Thanks for helping :)
[G4 Original Android Development] navendugoyal:
Recovery will be there if you install via TWRP. e.g Seven Hd Rom

It will be lost if you flash stock by LGUP.

[G4 Original Android Development] Follow_and_Feel:
Thanks a lot for the help that i got already! But I'm wondering why I can't install twrp properly the normal way? Why is it not working? I actually don't want to downgrade to 5.1, because I'm tired of setting everything back as I am used to on my phone, since you lose all the data (Had to set up my phone since I tried to install TWRP like 6 times).

Does anybody know why I'll always get this dead android after flashing TWRP exactly? Again:

- Bootloader unlocker

- Getting "Success" message when installing TWRP

- I'm on android 6.0

- Every time I install TWRP img and try to enter recovery I get a dead Android with a red warning sign

There must be a way to flash it without wiping, downgrading etc. :confused:

I'd really like to solve this riddle :(

EDIT: I am NOT rooted, since the only way I found to root android 6.0 is via TWRP, which I can't do because TWRP isn't working :( A vicious cycle that never ends :D Is there anybody out there with android 6.0 on the LG G4 and TWRP working???
[G4 Original Android Development] navendugoyal:
Hmmmmmm.

Read this article post on backup apps if you are worried about your setup.

It is easy to set it up as your current setup after flashing a new rom.

http://www.tomsguide.com/us/pictures-story/633-best-android-backup-apps.html

You have to go back to 5.1 --> root the phone --> install twrp --> install android 6.0 (rooted versions and custom roms available at xda - flash whatever).

This is because there is no root method for 6.0 as such available unless you have pre-existing custom recovery.

In your case you have to wait till someone releases a root method for android 6.0 without having a custom recovery or do as I have advised you to.

Choice is in your hands
[G4 Original Android Development] Follow_and_Feel:
Thank you very much! That was pretty enlightening :)

I think I stick around with the stock 6.0 OS and no TWRP running on my phone, until I really find something that needs to be flashed via TWRP. But thanks very much for helping :)

cheers

EDIT: I've done it like you said and I'm running rooted 6.0 with TWRP working. Thx a lot!

Hello,

If I am already on Android 6.0, Bootloader unlocked, is there any method to install twrp or to root without going back to 5.1?
[G4 Original Android Development] galerio:
What? So there is no adb fastboot to flash the recovery if I'm already on 6?

The followeng doesn't work?

fastboot flash recovery twrp.img
adb reboot recovery
<flash su>

Just tried: install goes well, but after entering recovery I get only an image of a dead android with a red triangle.

Ok, just installed the TWRP in this way:

So, it is possible to install recovery and also root directly on MM 20B

End of my story :)
[G4 Original Android Development] raduth:
It's not working for me.

When I type "adb reboot bootloader" in adb floder all I get is a dead android laying on the back
[G4 Original Android Development] galerio:
Follow this:

INSTALL TWRP

1 Make sure you have ADB and Fastboot installed on pc.

2 put TWRP.img in the ADB folder of pc

3 boot into TWRP with out installing it:

open a command prompt in the ADB folder (VERY IMPORTANT) and type:

adb reboot bootloader
fastboot boot TWRP.img <or whatever your TWRP image is called in your ADB folder>

That will re-start your phone straight into TWRP - You can transfer files to and from your computer while in recovery.

4 If you want to install TWRP permanently, copy your TWRP image to your mobile "while you are in TWRP RECOVERY mode" using the mount option in twrp.

5 then press install,

6 then select "images" ,

7 then select the twrp.img file on your phone

8 then select "recovery" NOT "boot" ,

9 then swipe to flash.
[G4 Original Android Development] raduth:
I did it till step 3. When I press mount, I have:

System, Date, Cashe, External_sd and USB-OTG. I have twrp image in my phone, how can i install it?
[G4 Original Android Development] galerio:
If you already have TWRP.img file on your phone then proceed with step 5 (install button is in home of the recovery)

I presume that you have already unlocked your bootloader, true?
[G4 Original Android Development] raduth:
Yes, I have already unlocked your bootloader.

I've managed to install twrp, but after this I flashed it with beta super su v2.52 and now I can not pass the vodafone logo. I cant make a fatory reset, also, after I pres Yes twice....nothing. What can I do?

When you install TWRP do NOT boot back into the OS.

Pull the battery and hold volume and power and go straight into recovery

When I installed twrp I kept rebooting and the OS was reinstalling the original recovery.

Boot into TWRP once installed.
