How to switch ROMs easier? - Google Pixel 4 XL Questions & Answers

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?

Help with Treble ROMs

I have the PRA-LX1 with already unlocked bootloader and got it rooted with TWRP + Magisk before the last OTA.
I'm not a beginner with rooting this phone but only got Problems with installing any Treble Rom (tried Lineage and Aosp) and every try ended with a bootloop I don't know what I'm doing wrong.
So please can anyone give me a step by step instruction?
Which Treble Rom is a good one and recommended for this phone?
Which TWRP do I need?
And how exactly do I flash them correctly? What do I wipe?
Sorry for this noob questions but I failed so many times with Treble and don't want to do the reinstall with erecovery for the 10000 time :crying:
Thanks

I googled it, pretty much every source says that you require a custom recovery in order to flash a GSI or any custom ROM.

Oh, well that's pretty cool. Either way, I just tried flashing Official Resurrection Remix GSI with no luck. Stock recovery, attempted to flash through fastboot and it just gives me a bootloop, exactly like TWRP does. Followed the guide you linked to etc, just keeps rebooting.

Well, I finally got it all working.
You know the risks, don't blame me if something goes wrong, I did these exact steps to manage to root my phone without breaking it. C432, Dual SIM and PRA-LX1.
Have everything stock before following this short guide: Firmware, all stock recovery etc.
Installing the ROM and GApps
First, download necessary GSI files.
(Personally I got Official Oreo Resurrection Remix, here).
(Although you could find yourself using virtually any other GSI, I like the look and feel of RR, though I'll be changing my boot animation with root). Many people would probably recommend you to use something like an AOSP, or LOS which I was also considering on installing. They may also come bundled with GApps, which would negate the later need for installation or download of separate GApps.
This may include GAPPS but you should understand this from the GSI page, so for example on RR I had to download both the latest base ROM .img and the micro GApps.
So to do this I had to use the right architecture (For the P8 Lite 2017, this is ARMx64, do your good research, since my problem was getting this wrong with my PRA-LX1 (Mine was A-ONLY), this stands for the base ROM and GApps.
After this I actually didn't use TWRP as user @ppdr07 advised. I followed the guide he linked us to and did as so, without following the -u command, since it wasn't working for me (didn't affect anything, try it, if it doesn't work, just take that bit out).
The ROM ended up installing and posting through, everything set up perfectly.
After this I was like "Huh, so what now? How am I to flash GApps on this without TWRP?". I went for it and booted into fastboot where I flashed Askuccio's TWRP for hi6250 devices. At this point I worried that the ROM wouldn't post again - though it did, so from there I enabled dev options and switched on advanced power options just for ease of usage. From there I rebooted straight to recovery which posted fine, too.
At this point, you need to flash the GApps. Go for the one that the original GSI page recommends. Flash it to the System Image partition. Don't wipe anything. At this point I recommend that if you realise that you forgot to transfer any files to the SD card, you should do it from the system. It works better compared to the MTP on TWRP. Either way, that should work properly. Now, reboot the system, and it should work perfectly.
Enjoy, it took me months to get to this point lol
Rooting Your New ROM With Magisk
(Before installing this consider the other root options. I believe there's SuperSU and another possibly that I'm less aware of. Either way, in my opinion Magisk comes with the most benefits so I'll be helping you out with that).
After this I ended up flashing Magisk in order to use Snapchat and other apps similar to it. Firstly you'll want to set up Google stuff which has been newly added to the system, and then you'll want to go to chrome and download the Magisk Manager .apk from here. The main and most reliable place to get it is from the creator's project page found here, all main links stand out in the middle fairly well.
(Remember to enable downloading of unknown apps for Chrome in it's app settings, otherwise it won't download or install.)
If it still doesn't work at this point, I ended up holding down on the Magisk Manager link and pressing Download Link (or something to that effect). From this point just install it as you would any other out-of-store app.
Now, you'll need to download these two files from the Magisk page onto your computer: Stable Installer and Uninstaller. Next, while booted into Android, copy them over to either Internal or External storage and when it's done, reboot into TWRP again, either by advanced power menu or using the button commands for recovery. Personally, I think I need the power options with this phone.
In TWRP, simply go to Install, navigate to /externalsd/***[WHEREVER YOU PLACED YOUR MAGISK FILES]***, then install the Magisk installer .zip. If unchanged, the filename should be something like "Magisk-v17.1.zip". Install it, then give rebooting a go. Hopefully it'll post, if not, go back into TWRP and run the Uninstaller .zip, it's saved me a bunch of times.
Unblocking Apps That Say Something Like "Your Phone is Rooted or Modified, no access blah blah blah..."
(Snapchat is the example used here. It won't work upon login if you don't follow this step. Some apps don't work with this alone however, though somebody may have produced a separate guide or easily installable Magisk module with a solution for it. One that won't be fixed singularly with Magisk Hide is Google Pay).
After posting, if you need to unblock Snapchat or something, go to Magisk Manager (which should now be more green), open the top left context menu, tap on Magisk Hide, and search "snap" until you see the Snapchat logo pop up, then select it, then back out with the back button. It should stay selected in Magisk, and the app should now be usable and shouldn't give you any annoying errors, if not give it a reboot and see if it's solved.
Good luck!

going to back to custom ROMS

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.

After rooting G9+ & installing an unofficial LineageOS 18.1, root was lost & need help getting it back

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?

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.

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!

Installing LineageOS via TWRP and not Lineage Recovery

Hello,
So after 7 years, I decided it was about time to get a new phone. I have an HTC M8, and will be slowly migrating to the Pixel 4a5g. I just bought one and it has been sitting in the box sealed for about a week. I havn't touched it yet. I've been reading the various guides for this phone, trying to do my homework before plunging in or asking questions. My goal in the end is to have a rooted 4a5g running lineage 18.1 with ability (Lineage or Proton or Elemental kernel--which ever works) of ACCA power via module.
The install guide for Lineage assumes you will use their recovery and not TWRP. And one of the steps has you temporally flash their recovery. According to previous posts the redfin test TWRP gives liimited functionality more so with a custom kernal (touch). And it seems one can get by without actually flshing a custom recovery and just booting it to the device via ADB.
So what I was wondering was if I could install Lineage without having to actually flash (temp, perm, or otherwise) a recovery, and actually do this via just booting twrp.img via ADB and thus doing the further required steps to install the rom and flashing the boot.img to root if desired. Just trying to get all my ducks im a row--I love turducken.

How to flash ASOP based ROMs?

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.
