Hello everyone,
I recently wanted to root my galaxy tab s2 and install a custom rom on it to enhance performance, someting i've done before with my old phone where everything worked fine. So i used autoroot to root the tablet which worked fine and choose to install lineageos afterwards. i found a fitting version of lineage on their official website, installed twrp on my tablet and used it to install lineageos and GApps. However i did not unlock my bootloader using adb since i didnt have to do that back when i rooted my phone and i read on a forum that unlocking oem in the developer settings would be enough. This is where the problems start. After i installed the custom rom the tablet would try to boot into the os for a couple of minutes only showing a loading animation just to boot straight into recovery mode afterwards. In an attempt to fix the error i used odin to install a stock rom from sammobile on the tablet. However now it doesnt even boot into recovery anymore. instead it only shows the stock rom loading animation until the battery emptys. Though i can enter download mode from that position and then cancel it in order to reboot the device which enables me to enter recovery mode. Does anyone have an idea how i could boot a normal os again or is the device hard bricked? The only idea i have left is trying to install a new os from an sd card.
I have the same issue. I installed unofficial lineageos 16 to exynos 2015 t810. I have newest odin and twrp. Im wondering if i need to install or unlock the bootloader to get past the logo loop then recovery bootup after 5 minutes. I followed clean tutorials.
Update: i found this to try.

- addonsu-16.0-arm-signed.zip
- open_gapps-arm-9.0-pico-20191009.zip (some with nano or stock)
I am doing a full clean install every time (over 10x so far) but only get it to boot using the ROM alone. Any mod, such as addonsu, gapps or even trwp app cause it to show the Lineage boot screen for quite a while until dropping back into TWRP. Since there is a virtually infinite amount of permutations which versions to try - can someone who is successfully installed 16.0 with Gapps on a T710 let me know their version combination please?
Thanks.
pico-20191009 is giving problems with the 1009 build on my T810 too. Pico-20191006 and Magisk 19.4 are doing the trick for me.
Don't know about other combinations
BTW, it's advised not to install the TWRP app as it is known for causing bootloops on this rom.
Don't know for sure, but wiping internal storage before installing rom might be useful too.
hello, I used to be a custom ROM junkie in the past but after some time i got bored and never did it again.
now looking at my current device which i never installed a customer ROM before its quite old as its running Android 8 and i would like to jump to 10 or 11.
I am confident i understand the process but its been a few years and i have some questions:
-for example this is the 1st device i encrypt so i am not sure if this affects.
-the device has no custom recovery so i have to start there but not sure if i have to remove encryption or if its ok.
-Also i would like to see if you have any advice for me or somehting i should pay attention beside install TWRP, format all but storage and install zip file for custom ROM
Thanks

You've missed all the fun with the upgrade to OOS 9.
So, you'll need to upgrade your firmware to 9.0.6 because all the latest ROMs require it. Take your time and carefully read https://forum.xda-developers.com/on...5-0-8-firmware-barrier-t3941164/post79758055.
You do not need to remove encryption (depending on how you upgrade your firmware).
If you've got a locked bootloader (which I'm expecting you do), them you need to unlock it so that you can flash TWRP. And unlocking will wipe all data from your phone. So backup everything you want to keep to your PC.
If you don't boot into recovery after flashing TWRP and install a patched boot image (see https://forum.xda-developers.com/on...ty-disable-oxygen-os-t3922324/post79357241)or flash Magisk, and reboot your phone, you'll lose TWRP because OOS automatically restores the stock recovery.
So the order is:
1. Backup
2. Unlock bootloader
3. Flash TWRP
3. In TWRP flash patched boot image (remember you're still on OOS 5.x so use the right one!) or Magisk.
4. Have fun moving to a custom rom.

I decided to upgrade to the G9+ after finding a LineageOS ROM for the phone. Root via TWRP & Magisk worked without a hitch. Then I installed the LineageOS 18.1 ROM from here: https://www.getdroidtips.com/lineage-os-18-1-moto-g9-plus/
Next I went to install GApps via the Aroma setup, but found that TWRP was gone. There was some limited recovery from the ROM installation which didn't seem to be of any use, so I reflashed TWRP & then Magisk, but I didn't get root back.
The phone now has a working version of LineageOS, but I can't even get the Google crap I need.
When I try to flash something via TWRP I get an error saying there was a "Zip signature verification failure", so I can't even get back to stock ROM to try again. (I guess this error is related to not having root.)
(I installed TWRP & Magisk on another G9+ with stock ROM and everything seems as expected. The phone is rooted. I just want to get rid off all the Google software I can.)
Anyone got an idea how I can get root back?

And any reason why "ADB devices" doesn't list the attached phone? "Fastboot devices" works fine.
Have u tested lineage, is
everything working fine?

Everything seems to be there, seems normal. Except root.

Have u tried superoot or something else instead of magisk?

The ROM that you're using is not meant to be daily driven, Erfan compiled that for experimental purposes, but that aside, there's a few things that you should take in consideration when using Lineage; It's not meant to be used with TWRP, that's why they ship their own recovery (Lineage Recovery). It's still possible to flash custom files with it (That doesn't match their original signature), you just need to skip a warning.
For Magisk, download the latest stable build from here: Download
(The .apk has the flashing script built-in, so just rename that to .zip).
One major difference from TWRP, is that Lineage Recovery doesn't support decrypting userdata, so the files must be flashed using ADB or USB OTG.
Use ADB Sideload as follows:adb sideload magisk.zip
As for me, I didn't unlocked my device yet, so if you could confirm me something: I need to know if I will lose my DRM certification, used for Netflix, Disney+, Prime Video and such.
Download Castro from Play Store, go to the DRM tab, and check the Widevine status, tell me if it remains L1, or if it downgraded to L3. That's what's holding me back from testing, or even compiling for this device.

Thanks for the response.
1. I'm using the Github Magisk 23.
2. Lineage Recovery is gone. I reflashed TWRP.
3. Attempting to use "ADB sideload Magisk-v23.0.zip" ADB responds "cannot read 'Magisk-v23.0.zip'"
4. I haven't got Play Store on the phone as I can't flash the aroma package (1.7GB) via TWRP.

I don't know anything about the other methods for getting root. I've always used Magisk.
(I'm working under the idea that as TWRP + Magisk works fine on one phone, they aren't the problem.)
Sapper Morton said:
The idea is to rollback to Lineage Recovery, you can even flash only the boot.img that it's inside the ROM flashable file, instead of reflashing the whole thing again. It's probably in payload.bin format, so you'll need a payload firmware extractor (Easily found on GitHub), in case you choose the first option.
• Aroma is not supported on Lineage Recovery, so I would recommend something smaller, like OpenGapps nano or stock.

What sort of idiots build in a crap recovery when one has obviously already installed a functional recovery, needed in the process of gaining root and installing LineasgeOS? This unnecessary included recovery wasn't in previous versions of LOS I've used.
Yes, this is an unpleasant surprise and I'm ticked off. I'm an end user who wants a relatively de-Googled phone, but now to maybe get a functional recovery I have to extract stuff from a payload file, but to do that I have to install more crud so that I can run the tool that does the extracting.
And I need Aroma to be able to select what I must have from Google. My partner needs their voice tech. I could dump almost everything else and use Pico. </rant> Sorry.
Is there no way to wipe the slate clean, get rid of this Lineage, and start again?
(I don't understand how installing their recovery could ruin the functionality of another recovery.)

On the second G9+ which I rooted but left the stock ROM, I installed Castro and it indicates L3.

Lineage is working fine, some details that will be fixed when releasing the new kernel
There is a method to root with magisk by patching the ramdisk its a way better rooting method then with twrp in fact magisk dev recommends this way of rooting if you have not tried this here is a magisk official link https://topjohnwu.github.io/Magisk/install.html
Hope This helped you bro
The ROM in the O.P. works.
Folks, I actually made a number of mistakes in this process.
The major one was to muff the fastboot command for flashing TWRP. I had followed instructions which said to boot TWRP, which didn't install TWRP, just loaded it into phone memory. But...
The ROM cited in the O.P. doesn't seem to have any problems that I have noticed in my usage, which is basically as a hand computer, not as a phone.
LineageOS now overwrites recovery with its own recovery, which is pretty moronic, because the user has already had to install a recovery to root the device.
But fortunately, if you have your ADB/fastboot apps handy with TWRP in the same folder it's an easy fix.
You should already have this stuff, but use the following software:
sebastian3367HD has provided TWRP for G9+ users onsight here. I'll assume it's called "twrp.img".
Magisk-v23 here -- put it somewhere easy on your phone.
Also get GApps 11. I used core NikGapps here, select latest date, then the version of GApps you want. (The core version 82MB just gives you Play Store & support software.) Put it the same place on the phone you put Magisk.
Assuming you've flashed the O.P. LineageOS ROM, which overwrites trusty TWRP, put your phone in fastboot mode, either using
1. power button + volume down
until you get the droid image on its back, or get there with your phone on, sending
2. adb reboot bootloader
via the windows command shell.
You're now in fastboot mode. You can now flash TWRP back onto the phone. Note that the phone has two slots of memory, so that the phone can hold two operating systems. If you send
fastboot flash recovery twrp.img
it will be flashed to the current slot, either A or B. To be safe you should flash both:
fastboot flash recovery_a twrp.img
fastboot flash recovery_b twrp.img
That gives you the safety of having TWRP in both slots. (Incidentally, TWRP allows you to changes slots.) (Also remember if you reflash LineageOS you'll have to put TWRP back on if you want a decent recovery program.)
Use TRWP to Reboot to Recovery.
Now install Magisk using TWRP:
Spoiler: (You know this)
a) choose Install
b) if the bottom right button says Install Zip press it and it will change to Install Image
c) if you put Magisk on your external SD card Select Storage to choose the SD
d) find and select Magisk-v23.0.apk, then
e) swipe to flash.
Then install GApps, basically the same as for Magisk.
Reboot to System. You should be rooted now and should have Play Store (and whatever else you opted for).

Thanks for the info. My problem was simple to fix, using the right commands!
I haven't installed that rom because afaik the source tree isn't available anywhere which seems kind of fishy, if anyone knows where they are please let us know
Hi
A few months ago I was able to flash on angelica lineage-17.1-20210326-UNOFFICIAL-angelica.zip and this worked well. Yesterday I tried to flash the s same image again and after several attempts I get a black backlit screen when lineage is meant to start. I reflash stock _V12.0.10.0.QCRMIXM then a recovery - PBRP 3.0.1. From there I was having issue
What is the flashing process for an unlocked device that has something like TWRP/Pitch Back/Orange Fox installed?
I guess once you unlock and can flash the recover you use the recover to flash the zip, then reboot and flash magisk.zip and everything should work? Or is there some step missing.
I had this problem too with the google pixel 7 pro. Can't help ya there on that one. I even tried re installing older firmware and it still didn't work. Maybe the bootloader is permanetly downgradable but the firmware of the stock is. Just a guess. Lineage os 20 is an unofficial build at the moment that receives hardly any updates.
Hi guys,
I recently purchased a Pixel 4xl and absolutely love it so far. I managed to install lineageos, magisk, and LSPosed. It took me a little while to get things working as I am new to root etc. I am basically learning as I go.
I am getting bored with lineageos. I would like to try some other ROMs out. Is there an easier way to flash custom ROMs instead of using a PC? I my video card in my PC bit the dust so I am waiting for a replacement.
Thanks,
Rocky
Flash TWRP. Download ROM.zip on the phone and put it in a known place.
TWRP always allows flash custom ROM, while recovery from lineage - not always.

I was under the impression that you could only temporarily boot into twrp on the Pixel 4/xl?
