[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.

I am using latest version: RS98810d
Step 4: flash recovery finished without error but cannot Power Off when press "Power" for 10 seconds so I unplug batterry then plugin again and press "Power+Volume down" but it cannot so I tried run command "fastboot boot twrp-3.0.2-1-rs988.img" after re-flash recovery but system shows:
=======================================

After flashing recovery, unplug USB cable and pull battery. Put battery back in, then press and hold volume down (hold volume down entire time) and press and hold the power button, when you see the lg logo, let go of power button for 1 second and then press and hold power button again until it reaches factory reset screen. One at factory reset screen select yes both times and you'll enter TWRP. When using the buttons remember to never let go of the volume down button only the power button for 1 second at lg logo.
You can also try after flashing it:
adb reboot recovery
Note: you must reflash TWRP if you allowed it to boot into os without flashing SuperSU or magisk.

It is stated instead of doing that you turn off the phone and boot into the recovery with power+voldown

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.

Is it work on h860?

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.
Here's the link and info for LG bridge and using it to check for updates:

flash TWRP successfully,how into TWRP recovery mode?

install TWRP successfully.
power off phone,
hold volume down +*power*button ...see lg logo,let go of power button then quickly press it again,into factory data reset screen,
it's show:
delete all user data(including LG and carrier apps) and reset all settings? choice ''yes'' twice,then it reboot to factory reset/wipe data,not into TWRP recovery,what's wrong? is TWRP flash failed?
How go to TWRP recovery mode??

Once your on the white page to format wipe just hit yes twice. This will boot to twrp.

For me it worked to
(backup all your data! If it fails, it erases everything on internal sd.)
1. flash twrp via adb
2. while phone is still in fastboot, press and hold volume down and power till lg bootlogo appears, release power for half a second, press it again till it asks you to wipe.
3. Where it asks you to wipe, choose yes, 2 times. It should not wipe but boot twrp.
4. I dont know if this step is necessary but i did it and it works now: Flash the twrp.img in twrp again (to see .img files in twrp, click on install image), choose recovery as partition.
Now it should be installed correctly. To boot twrp just power off your device and press and hold volume down and power till lg bootlogo appears, release power for half a second, press it again till it asks you to wipe. Choose yes 2 times.

at wipe screen，I hits yes 2 times,but it go erasing data screen, twrp not boot, what's wrong? flash twrp again?
thanks

When booted up, K4 note boots till boot logo and restarts in an infinte loop

Hey!
I tried to unlock the bootloader of my K4 note (with stock marshmallow rom) yesterday with
fastboot oem unlock
The unlock succeeded when I pressed the Volume Up button to confirm it. Then it showed me a screen to select where to boot(system, recovery, bootloader). I had to scroll the options with the volume down key, and then select it with the volume up key. But none of the volume rocker buttons responded. I couldn't select where to boot. Then, with the fastboot flash recovery command, I flashed the TWRP for stock ROM available in the Download section of this thread. But still the buttons did not respond, and fastboot reboot bootloader gave me this message:
C:\Users\Kartik Shankhavaram>fastboot reboot bootloader
rebooting into bootloader...
FAILED (remote: not support on security)
finished. total time: 0.012s
Click to expand...
Click to collapse
So I did fastboot reboot, and since then, the device has gone into an endless boot loop. It shows me the boot logo, then vibrates and restarts again.
When I press 'Power+Volume UP', I get the message
Have been in factory mode, Long press the power button and the normal boot
Click to expand...
Click to collapse
Then, it starts the loop again.
With 'Power+Volume Down', I get
Have been in meta mode, Long press the power button and the normal boot
Click to expand...
Click to collapse
and the same loop happens.
I read many articles about this and most of them suggest a problem with hardware or water in the phone. But my device was working when I connected it and not a drop of water fell on it, nor did it fall anywhere.
I'm at a loss and don't know what to do. Any help would be appreciated.
Thanks!

You need to flash stock ROM again.
And, after unlocking boot loader, you need to reboot to system properly and flash recovery

Stuck in fastboot after failed try to install lineageos for Redmi 7a

Newbie
I installed twrp on a Redmi 7A, I followed instruction to wipe the phone but at the moment to install the os image (which I am not even sure is working) I realised I copy the wrong file, so I poweredoff the pone to get the sd card to copy it and when I repowered I am stuck in fastmode.
sudo fastboot flash recovery recovery.img
sudo fastboot reboot
Keeps me in fast mode.
Is there anyway I can reboot with TWRP?

aside from the obvious power off then powering on pressing the power button and volume up, then releasing the power button when the phone starts, You might want to reflash via adb the boot.img and recovery.img you downloaded, to see those commands, go to this post:https://forum.xda-developers.com/redmi-7a/how-to/guide-twrp-root-magisk-custom-rom-t4027441

Thank you I'm now out of the fastboot and ave a working TWRP.
The only problem remaining is that my phone keeps on rebooting and again and again being stuck on the Redmi splash screen.

Unable to boot into newly-flashed recovery from fastboot (LineageOS 18.1)

Recently got a hold on the T-Mobile version of the OnePlus 6T. Already have a OnePlus5 running LineageOS as well and thought the installation would go as smooth.
Following these directions, I got through unlocking the bootloader (with the unlock_code.bin from OnePlus) and I thought I'd gone through flashing a custom recovery. I was able to boot into fastboot, ran # fastboot flash boot lineage-18.1-20210506-recovery-fajita.img, and shutoff the device. Now I'm stuck in a bootloop at the screen indicating that the device has been unlocked and data can't be verified.
While still connected to my PC, any combination of Power + Volume keys will flash the display and instantly go back to the bootload screen. The only way to shut-off the phone is to disconnect it and do either Power + Volume Up or Power + Volume Up + Volume Down; Power + Volume Down to try and boot into recovery does nothing. Plugging in the phone while off auto-starts it back to the bootload loop.
I can turn on the phone while disconnected, but the only way to escape the bootload loop is to boot straight into fastboot with Power + Volume Up + Volume Down. From here I can connect it to the computer and it's seen as a fastboot device. From here, however, any of the options will reboot into the bootloop.
Is there anything I can do from here? It's not a hard-brick, but I'm not sure why I'm stuck in a loop. The flashing of the recovery seems to have worked, no issues with A/B as stated could happen in the docs. I'm at a loss.
Code:
Sending 'boot_a' (65536 KB) OKAY [ 1.573s]
Writing 'boot_a' OKAY [ 0.365s]
Finished. Total time: 1.947s

Data can't be verified? It does let you run fastboot commands, just not send files?
Most people on this device use TWRP. I have a guide here.

Yes, I can get the fastboot menu, but trying to boot from the lineage recovery image would take me straight to the warning page indicating the device is unlocked and to not store confidential data.
I just tried using the guide you posted to go with TWRP, but I'm having issues again with booting the recovery. Followed every step: downloaded the ROMs, flashed them all to the phone as per your script, was able to boot, chose the language and wiped, and once in the phone rebooted into the bootloader. But similar to before, I run # fastboot boot twrp-3.5.2_9-0-fajita.img, but now the phone seems to be stuck on the OnePlus logo with the words Fastboot Mode underneath.

You may need to start over. I the unfortunate part here is the TMobile 6T is a bit different and complicates things. Recent TMobile MSM Tools have been posted in the TMobile thread, they just aren't in the OP. I'll be honest I don't follow the TMobile devices, so I don't know much about what's best to use between versions and international tools and what not. There are a few TMobile users that posted in my Guide thread that you may want to tag and see if they can help?
