LG LGMS550 Stylo 2 Plus?

Just delete this if it's considered in the wrong place. If and when is the the Stylo 2 Plus getting its own forum and has anyone come up with an exploit for rooting this phone yet?

Hiya
Yes this is the wrong place. This is for the g stylo not the stylo 2 plus as can be seen in the name of the forum.
No there is not an exploit yet. Kingroot, kangoroot, one clove root, etc all do not work yet. Soon i would imagine
I even have trouble looking on the web for things because it seems we share a model number ms550 with the lg optimus m. Weird

You think my signature would say I probably know this. Granted, I haven't worked for them in a while, for XDA, even longer. I was talking to the mods of the forum, sorry, if I confused you.

Root recovery and boot loader unlock have been achieved on the Gsm Variants . you can find the link if you look for it .

Should say lg something
If it does fastboot oem unlock
Reboot the phone
Enable developer options again in the settings menu by clicking build number
Go back to command window put it back in boot loader screen type fastboot flash recovery recovery.img

Now click thanks!!! If I helped.

I followed all of these steps. Fastboot flash recovery recovery.img from the directory where the tools are. When I get to the part of pressing volume down, power, then releasing power, and pressing again, and releasing both this is what happens:
Factory data reset screen
Erase all user data & restore default settings?
No
Yes
I've already been through that and TWRP doesn't load if I pick Yes, it just wipes my phone data, fresh Android, start over.

Fastboot said it flashed successfully. It copies the file, says it's ok. I would think if it didn't flash, it would fail the fastboot flash command. So is my phone jacked? I've read about how Android can rewrite the recovery partition as a security measure, or disable flashing by other means. Some kind of added security possibly?
Why would it say OK when I flash recovery, but NOT actually flash it?

The recovery.img you sent also said it flashed, but I got to the same Android factory reset screen after the key press procedure (volume down, power, release power, repress power, release all)

Once you boot into recovery, let the screen fully dim, do not touch it... once the screen is completely blacked out, turn it back on and all touch features will be up and running... and don't mess with the adoptable storage feature..migrating data.. because TWRP will not recognise any data if you have this enabled.

okay, um....u can just save urself a lot of trouble, because there is no stock android firmware directly from google EMUI is all you get for this phone
u can only install google apps, an alternative launcher and clean up your system apps via root to get "closer" to stocl android, but it still wont be stock android!
concerninf reboot into recovery, try all button combinations!
1: vol up + power
2: vol down + power

[Root][RS988] Rooting RS988

Now that LG has released the bootloader unlock for the RS988 it can now be rooted.
------------------------------------------------------------------------Disclaimer---------------------------------------------------------------------------------------
This post is meant to be educational and I am not responsible for any lost data or damaged devices resulting from the following instructions
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
-----Instructions on Unlocking your bootloader can be found here---------
WARNING THIS WILL FORMAT YOUR DEVICE
https://forum.xda-developers.com/lg-g5/development/official-european-lg-g5-h850-bootloader-t3363040
The only difference is selecting RS988 when selecting your device
---------------------------------------------------------------------------------------
Requierments:
ADB
fastboot
An RS988 LGG5
The working (though not entirely tested!) TWRP image is found here https://build.nethunter.com/test-builds/twrp/lge/twrp-3.0.2-1-rs988.img (Thank you jeffsga88 for finding this link)
The Latest SuperSu Binary
Step 1:
Make sure your RS988 is fully updated, the rebooting into the bootloader is only unlocked in the most recent updates.
Step 2:
Enable Developer options and USB Debugging
Step 3:
Enter Command
Code:
adb reboot bootloder
Step 4:
Once in bootloader run
Code:
fastboot flash recovery [path to twrp image on your pc]
Step 5:
Turn off the device DO NOT let it boot back into android!!
If you do boot back into android, you will need to re-flash TWRP (Steps 1-4)
Step 6:
With your device unplugged, hold power and volume down, releasing the power button for a moment when you see the LG logo, then
re-pressing the button to enter recovery, on the following screen select yes both times
Step 7:
(The Following Text other than step numbers is written by and entirely created by jcadduono, and can be also found at his post at https://forum.xda-developers.com/lg-g5/development/recovery-team-win-recovery-project-lg-g5-t3363047)
At this point, you will see the TWRP splash and reach a screen asking you if you want to allow system modifications.
By swiping right, you will trigger dm-verity, and if you don't follow step 8 you will be unable to boot!
If you are going to root your device or follow the rest of these steps, then it is safe to swipe right and enable modifications.
Step 8:
Only if you want internal storage or data to work in TWRP:
Go to [Wipe] -> [Format Data] (not advanced wipe) -> type "yes".
WARNING: This will wipe your internal storage, disable encryption, and factory reset your phone!
Go to [Reboot] -> [Recovery].
Step 9:
Please consider backing up your stock boot partition in TWRP before proceeding to the next steps!
Step 10:
If you want to be rooted with SuperSU:
Download the latest SuperSU stable by Chainfire.
Without exiting TWRP, transfer the SuperSU zip to your device over MTP* and flash it using [Install] in TWRP.
-or-
If you only want a bootable system partition or writable data in TWRP:
Download dm-verity and force encryption disabler.
Without exiting TWRP, transfer the no-verity-opt-encrypt zip to your device over MTP* and flash it using [Install] in TWRP.
Step 11:
Go to [Reboot] -> [System].
---------End of jcadduono post clip-------------
Now upon reboot, the phone may loop a few times and take up to 5 minutes to complete the process.
When you get into the device, run through setup as normal and you will have SuperSu installed and you will be rooted.
I can not verify Magisk Root Yet but will be attempting to do so soon.

You guys that have the rs988 you may want to ask one of the devs to add support for LOS and custom ROMs. But don't bug them either.
Maybe @King_lilrowrow could help if he has time, although I know he's been busy lately with other things. Hopefully someone will help you guys out. I have no idea how to, otherwise I would try and help. Nice you guys have rootr and twrp finally though.

You can also try after flashing it:

No problem! Glad we finally have it on RS988

I've held off on unlocking the bootloader and rooting, since it seems there currently are no ROMs available for the RS988 to flash. Basically you just end up with rooted stock?

Yes, currently all you can do is install TWRP and root stock. You can also install some audio mods like viper, but no custom ROMs yet for this version of the device.

Is there a touch TWRP recovery available? Granted I'm not sure if I will be able to flash it, since my power button is broken.

Yes it's touch TWRP, can't even remember last time I saw a non-touch based one, been at least 3 years or so. Anyways it's located in the op. As far as flashing it, I believe you can do it without the power button. The issue will be rebooting to recovery after flashing it to flash SuperSU or magisk (if you don't do that or at least get into TWRP before first bit after flashing and delete the recovery from boot.p file, TWRP will be overwritten by default recovery and you have to flash again). While in fastboot mode, after flashing you could try and use:
Code:
adb reboot recovery
Not sure if that will get work or not while in fastboot mode, but something to try since your power button is broke.

You can always check using LG bridge and use update feature. If just wanting to know because your wanting to root and get TWRP, try and follow the guide. If you're not on latest version you'll know because you won't be able to unlock the bootloader using fastboot. If you can unlock your bootloader, you're good to go.

[Solved] Trying to flash TWRP, fails to boot into recovery.

Hi everyone,
I'm no stranger to flashing custom ROMs or recovery on my devices, but I can't figure out for the life of me how to get TWRP on my LG G6 (H870)..
I flashed the recovery partition using fastboot, which outputs:
Code:
> fastboot flash recovery twrp-3.1.1-0-h870.img
target reported max download size of 536870912 bytes
sending 'recovery' (21348 KB)...
OKAY [ 0.567s]
writing 'recovery'...
OKAY [ 0.218s]
finished. total time: 0.786s
Then I use
Code:
>fastboot reboot-bootloader
rebooting into bootloader...
OKAY [ 0.020s]
finished. total time: 0.021s
This restarts the device.
I then immediately start holding the power and volume down buttons and as soon as the logo appears, I let go and hold the buttons again. (this is described by a few websites as the way to do it).
The device reboots twice and then boots straight back into the stock ROM that was shipped with the device. TWRP is gone after that.
Does anyone know how to get into TWRP before it is overwritten by the stock ROM on boot?
EDIT:
When trying to boot from the recovery image, I get the following error:
Code:
>fastboot boot twrp-3.1.1-0-h870.img
downloading 'boot.img'...
OKAY [ 0.546s]

Hi everyone,
I'm no stranger to flashing custom ROMs or recovery on my devices, but I can't figure out for the life of me how to get TWRP on my LG G6 (H870)..
I flashed the recovery partition using fastboot, which outputs:
Then I use
This restarts the device.
I then immediately start holding the power and volume down buttons and as soon as the logo appears, I let go and hold the buttons again. (this is described by a few websites as the way to do it).
The device reboots twice and then boots straight back into the stock ROM that was shipped with the device. TWRP is gone after that.
Does anyone know how to get into TWRP before it is overwritten by the stock ROM on boot?
EDIT:
When trying to boot from the recovery image, I get the following error:

This has been repeted endlessly, after flashing twrp you need to press and keep pressing power and vol- until it turns off, then press and keep press both until the lg logo, leave the power button and immediately press it and keep press it until you reach the reset instructions, follow them and it'll boot in twrp.
Oh and this is written in the installation instructions in the official twrp thread, both fastboot boot and fastboot reboot recovery command won't work.

So to be clear:
adb reboot bootloader
fastboot flash recovery twrp.img
fastboot reboot
hold POWER + VOL- until LG logo
release POWER briefly but keep holding VOL-
hold POWER + VOL- again while the logo is still displaying
wait for reset instructions
?
Because, at step 6~7, the phone just reboots because I'm holding POWER and VOL- too long (about 7~10 seconds).
It also shows the orange warning that points to http://g.co/ABH while I'm holding the buttons.

This is the correct way to reboot in TWRP the first time, good luck :fingers-crossed:

Yep, that's what I've been doing the whole time.
I think the recovery file I downloaded was corrupted during download or whatever, because I downloaded it again (same link, exact same filesize) and tried again and now it worked first try!
Thanks for your help and patience !

No, you didn't follow the procedure and you don't read carefully what @Killua96 wrote: you don't have to use “3. fastboot reboot“ adb command. Instead of it follow Killua96`s advice “after flashing twrp you need to press and keep pressing power and vol- until it turns off“
Just simple as that.

I guess I didn't explicitly mention this, but I have tried both ways.
Maybe my timing was off, I don't know. Anyway it's working now. Thanks for the suggestion!

You're always welcome.

Is there a way to flash twrp without wipe all data? I flashed a newer version but couldn't use twrp anymore, because I should wipe my data... (like the first flash....) with the old version of twrp I couldn't mount my external SD card, so it wasn't able to made a full backup. (not enough free space on internal sd)

Excuse my double posting... ?

The 1st time it tries to boot in system. If you stop it with the same key combination (vol-, power), the 2nd time you will get into recovery!
(then the decryption issue will start, where I am still blocked)

I have the same issue. I've downloaded the twrp 3.2.3 for my G6 H870. I've unlocked the bootloader and it seems I flashed the recovery successfull. After flashing it I shut down the phone by pressing Vol- and Power and try to boot into recovery by the known Vol- and power with short release of the power-button. But still it brings me to the factory-reset-page. What am I doing wrong?

When you successfully flash twrp using your computer by typing "fastboot flash recovery recovery.img"
You will see something similar to this:
target reported max download size of 536870912 bytes
sending 'recovery' (21348 KB)...
OKAY [ 0.567s]
writing 'recovery'...
OKAY [ 0.218s]
finished. total time: 0.786s
When you seee this......Unplug phone from computer then hold power and volume down.
Then after a few seconds it will restart.
Keep holding power and volume down.
Soon as you see lg logo keep holding power and volume down....but soon as you see lg logo keep holding volume down but release finger off volume for half a second and press and hold power again until you get to the white reset screen.
Use volume down to select "yes"
And again on next screen use volune down and select "yes"
It will NOT reset your device....it wil instead, after a few seconds boot into recovery.
Then in recovery flash either supersu.zip or magisk.zip
.
30 seconds at most it will then be successfully rooted.
Then restart your phone.
If it says that recovery is not instslled or do you want to install recovery...select NO....restart phone and voila...you have twrp and a rooted G6.
Matt.

For me, the problem was that the latest TWRP version https://dl.twrp.me/h870/twrp-3.4.0-0-h870.img.html did not boot into recovery. Instead, only the previous version https://dl.twrp.me/h870/twrp-3.3.1-0-h870.img.html works. Very strange. Apparently there will be a new version of TWRP soon so lets hope and see.

[SOLVED]Tried to update Magisk from app, stuck at Fastboot screen, TWRP may be gone

I fixed the problem by just booting into the LG Factory Reset menu, in order to get into TWRP. I hesitated to do that for a while because I had no way to verify TWRP was still on my device. After running out of options, I decided to just go for it. To my (and probably no one elses) surprise, it went straight into TWRP, where I was able to flash H91820s and Magisk 16.0 in the same TWRP session. Rebooted, everything was how it was except on a new version of Android. Root was retained.
Tried to update Magisk on my TMobile H918 from Magisk version 16.x using the app, and selected Direct Installation. The device is now stuck at the fastboot screen, and I cannot boot into recovery from adb.
Is there a way I can repair things? I am unsure exactly what got deleted/corrupted in the process of the update.
EDIT: When I try to boot into TWRP, I get this error:
fastboot: error: cannot load 'recovery': No such file or directory

and when I try to re-flash TWRP, I get this error:

Can you get in Twrp with button combo? For me its while boot hold vol down and power then at lg logo release the power for a sec and re hold until the while screen and then select yes twice.
There is also download mode and reflashing twrp that way I believe...
Dont 100% me on that .

I tried to boot into recovery, but adb detected no recoveries on the system.
I don't want to do the System Format Yes Twice thing because I believe TWRP is gone. And I am unable to re-flash due to "no such command."
The recovery is unable to be written to the device.

Is the phone in download mode ?
adb doesn't work in download mode
What does the command fastboot devices return?
