Pls help a noob here

To install the twrp i must unlock the bootloader before is it right?

After unlocking there is any step by step guide?
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] Zaxx32:
Dunno if it's changed much...you'll prolly have to do some homework tho...not super 'noob friendly' but ask Qs in the Q & A section and search helps too...:geek:

I was able to flash it yes, however could not access any data on the device due to encryption password I could not get by. I assume wiping would fix this but did not test.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] d33dvb:
Installation steps I took that ultimately ended up wiping data for no reason and still twrp did not stick on reboot.

Reboot to fastboot mode.

fastboot flash boot_a sunfish_twrp11-test2.img

fastboot flash boot_b sunfish_twrp11-test2.img

Use volume buttons and select Recovery mode and tap power button.

WARNING YOU WILL LOSE YOUR DATA. MAKE A BACKUP FIRST

Tap wipe, Format Data

reboot recovery

adb push sunfish_twrp11-test2.img /sdcard

Install, then Install Image, choose /sdcard/sunfish_twrp11-test2.img

Install recovery ramdisk and swipe to flash

adb push lineage-18.1-20210617-nightly-sunfish-signed.zip /sdcard

adb push blu_spark_r105-pxl4a_f65bf4cba.zip /sdcard

Install and reboot, works, but back at lineage recovery on next boot, so Im at a loss. YMMV
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] mangokm40:
Interesting...

You flashed TWRP first, and custom kernel (blu_spark) at the end.

Nikamura's instructions here seem to indicate kernel installed first.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] Android.Addict:
You need to write TWRP to Ramdisk if you want it to boot into twrp after you reboot until we get recovery.zip

I built TWRP for android11 test3 build with June firmware.

There is link at OP.

I tested it with android11 FW(RQ3A.210605.005 Jun 2021).
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] DragonFire1024:
Was just about to tell you that safety net fails within a few minutes on test2. As soon as you flash your final safety net patch you get a few minutes where everything works as you expect it. Then within a few minutes safety net is completely lost. Have not tried test3 yet due to the frustration from test2.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] DragonFire1024:
The password or pattern, I can confirm the pattern works, is whatever password or pattern you set up for your lock screen. I'm not sure if it would ask you for a password or pattern if you had just set up FRP or biometrics, which is generally done when you first set up the device. If you just bypass the encryption by pressing cancel, yes you will be locked out of data functions or most of them.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] Nuke1999:
Hello, just tested test3 for the June firmware. Upon initially flashing the twrp_boot.img, I am able to use TWRP normally. As soon as I flash the twrp_boot.img via TWRP and save to ramdisk, then reboot to recovery, I get no touch response via TWRP. In case the context matters: I sideloaded the June OTA update via ADB from Feb stock image; I also ran the following commands to flash the image:

fastboot boot 'twrp_boot.img'
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] mangokm40:
Which custom kernel did you use?
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] Nuke1999:
no custom kernel was used.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] Slim2none4u:
Thats your problem. To install TWRP, you need LZMA support kernel.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] TheSayaMan:
How exactly is the kernel installed? I installed via EX Kernel manager app then installed TWRP by instructions and it won't boot. Stuck at animation.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] Nuke1999:
shoot, should've read up on it a bit more.

Edit: to be fair... test3 does not explicitly say that you need to use a kernel with LZMA support. whereas test2 does.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] TheSayaMan:
No clear instruction because I have no idea how to install the kernel. All it says is must use LZMA support kernel. I've tried flashing it in fastboot and even tried installing it through franco kernel manager and EX kernel manager apps and I can't get my phone to boot up. It stays at boot animation in either case for me.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] TheSayaMan:
ok, I got it to work but after flashing magisk to root, twrp is gone so I don't get the point in this.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] mangokm40:
Nikamura's instructions are here

Did everyone follow these steps? If TheSayaMan followed these, and lost twrp when reinstalling Magisk, nikamura probably should be alerted.

If you post here, maybe put details as to each step you took. That, in addition to the results, is going to be needed to troubleshoot.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] Zaxx32:
Absolutely following!!
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] TheSayaMan:
I'm pretty sure but not positive that on these

I'm pretty sure but not positive that recovery uses boot.img and so does magisk, so by flashing magisk patched boot, you are then overwriting the twrp boot flashed previously.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] Slim2none4u:
After installing twrp, to install magisk, don't patch the boot image. Instead change the magisk apk to a .zip by simply changing it from Magisk-v23.0.apk to Magisk-v23.0.zip and flash it in twrp.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] TheSayaMan:
Thanks a million. I'm going to do this!!!
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] TheSayaMan:
That did the trick. Thank you!!!
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] TheSayaMan:
I can answer this one. After you install lineage zip, and before you reboot, in twrp, re-install kernel image as boot and twrp recovery image as ramdisk per instructions, then twrp will stick. The problem is, after you flash lineage, the recovery is overwritten with the lineage recovery. If you reinstall twrp before reboot then lineage recovery will be overwritten with twrp and all will be good. Tested and works.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] TheSayaMan:
It is. I also tried flashing it with my USB flash drive with LOS recovery and it worked as well.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] thedemon786:
i love using the 'flashig magisk zip' method to get root. easy to update also. just unroot and install ota from adb sideload and then root again by temporary going to this twrp and flashing magisk again.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] Slim2none4u:
For those installing Magisk via custom recovery as I suggested earlier, you should read installation faq here

https://topjohnwu.github.io/Magisk/install.html

Just so you're informed.

Is there a step by step installation procedure somewhere? I'm on stock July. Missing TWRP back ups!
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] TheSayaMan:
First off

First off you need to flash back to June because this is untested on July update. Steps are located here. https://xdaforums.com/t/twrp-3-4-0-0-for-sunfish-testing.4179101/post-85165057
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] Zaxx32:
Didn't realize it was that sensitive to OTAs....damn :unsure:
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] TheSayaMan:
ok, so I ota'd to July and the kernel here does not work. I used the July Kernel from EX Kernel manager and it works fine, so if you update to July, do not use the kernel here.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] tcat007:
Are you using a PC for the fastboot commands, or are you using your phone for all? TWRP Test3, EX kernel, and magisk, are the 3 files needed, right? (On July stock). Do you lose any data?
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] TheSayaMan:
You will not lose data and the only fastboot command I use on PC is fastboot boot boot.img to temporarily boot twrp. After this, PC is not needed and once twrp is installed permanently, PC should not be needed. Just understand that if your on stock, you will more than likely not be able to OTA because it will probably fail because twrp is installed. I'm on LOS custom where it will update because its a custom rom. If you update on a custom though, after you install rom, you need to flash kernel and install twrp again before you reboot phone, otherwise twrp will be overwritten by whatever custom rom's recovery is.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] mangokm40:
Sir,

If we turn off "update LineageOS recovery" in the Updater screen, do you think we can keep

TWRP & kernel after OTA update?
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] TheSayaMan:
Do not auto update because twrp will be overwritten by LOS recovery and so will the kernel. I download the update on lineageos.org website and save to my internal storage along with the twrp.img, magisk.zip, and kernel.zip. I reboot to recovery. Install lineage update zip. Then install kernel then install twrp per directions noted on previous post. The gapps survive so no need to reboot to recovery and reflash those. Just flash the magisk.zip to get root back. Boot to system. It will finish updating and you will have permanent twrp and rooted if you flashed the magisk.zip.

[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] TheSayaMan:
This error pertains to the parallel apps or multi user ID. If you are not sure if you have parallel apps running on your phone, you can do a quick check by going into your Root browser and look in these locations.

/storage/emulated

/data/system/

data/system_ce/

data/system_de/

data/misc/

data/misc_ce/

data/misc_de/

data/user/

If you see any folder named 999 then you have parallel apps enabled on your device. TWRP in it's current form will not allow you to create a backup or restore a backup with parallel apps enabled.

[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] daemonspudguy:
For some reason mounting /data is an invalid argument. That's bizarre
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] daemonspudguy:
Anyone have any ideas as to why this is? @nikamura do you have any clue?
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] EngineerMind:
My guess is that @nikamura created this version of TWRP to work specifically on the Pixel 4a running stock A10 (maybe for his immediate needs), and he posted it anyway just in case it could be helpful to others.

And I thank him for that because I am sticking with stock A10 and combined with the custom kernel that supports compression, it is working fine for me - even the image backups and restores.

There is even a config mod for this TWRP that enables the "Internal Memory" checkbox so that the backups can also include the internal memory if desired.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] daemonspudguy:
Apparently this happened specifically with ROMs in August, as other ROMs from before August were supported and working.
[Google Pixel 4a ROMs, Kernels, Recoveries, & Other] EngineerMind:
That is strange.

[Android Q&A, Help & Troubleshooting] Kohlrak:
begin edit:

Eh, no one seems to have an answer. I'm just going to learn to live with it. If you found my post, may you have more luck than me.

end edit:

Lemme get the things out of the way that I don't think are particularly relevant:

I"m using a Samsung Galaxy TAB E, without the GSM slot, but this appears to be in google's area in particular, not Samsung's.

I'm using marshmellow, which might matter, but I bet this was never fixed, given how things like this work (mainly, once i rooted, i have gotten afraid of upgrading for fear that old apps i like quit working and possibly even loosing my root).

I had to replace the battery at one point (i doubt it's relevant, but apparently the camera autofocus bug involved what day of the week it was).

So, the actual problem. Smart Manager, powered by Clean Master, i can let that thing sit for hours or even days, and it'll never finishing checking how much space i have. I'm using adopted storage, not that it matters, because things appear to be installing to actual internal memory, anyway, because the actual space i have left is several gigabytes, but google play is saying i only have 1GB remaining, and it won't install updates that are only 200MB.... Meanwhile, I got a notification that I only have 2 or 3 GB remaining. If I use DF (via the Termux app), it tells me /mnt/knox has 1GB free, /storage/emulated has 22.9GB free, /efs, /cache, /persist, /firmware, etc are all incredibly low, but i think this was intentional. /su has 24.5MB, and /storage, /storage/self, /dev/sys/fs/cgroop, and the like are all reporting 704.5MB about.

The obvious conclusion to me is that DF is telling me the truth. I want to say that google play and other packages are using some sort of "free space cache" rather than actually calculating how much space is actually free on the device.

The question: How do i find said "free space cache" and forcibly delete/fix it and if it doesn't exist, how can I figure out what's actually on internal memory so i can move it and symlink to it with my root powers?

I have root.

This isn't my first rodeo with linux.

I have command line access through Termux.

Android Studio is way too bloated for my potato of a computer, but I do have access to gcc in Termux if necessary.

People on reddit seem convinced that because their phone doesn't work then no phones work, and google sucks and why don't google listen to me, and i'm getting an iphone.

I put a case (spigen tough armor) on my phone and I can't hear a squeak. Maybe if I took the case off and tried to squash my phone I'd hear a squeak, but why would I want to do that? I wouldn't have thought there'd be much give; it's unlikely to be a case of "first it squeaks and then it breaks" because you can't push it that far. Perhaps if you pushed it really hard.... But it reminds me of the old joke "Doctor, it hurts when I do this"..."Well, stop doing it then".

Despite the negative commentary your device clearly has a build problem and should be managed under warranty. While I always use a case (spigen) that should not be an expectation unless specified by manufacturer and included with device.

FWIW - I do not have that issue (phone still feels solid sans case) but also use & carry it in a manner that rarely flexes the body/frame.

Mine creaks sometimes but its a budget device made out of plastic. Can't be expecting flagship level build quality.
[Google Pixel 4a Guides, News, & Discussion] DB126:
Respectfully disagree. Used lower end Moto phones for years, some half the price of the 4a. Never had a build quality issue (might have got lucky too). Plastic can be fine if overall structure is properly engineered. So far no issues with my 4a but it also rides in a protective case.

[Google Pixel 4a Guides, News, & Discussion] DrupadSachania:

My pixel 4a was making noise when pressing in the back under the camera and between the power and volume buttons, as well as over the power button. I ordered a replacement from Google but after few days, the same noise at the same location came back on the new device.

Despite I love this phone, I wouldn't have bought this device if I knew about this issue. I believe this is due to a bad internal design plus the heat of the CPU (actually the heat comes from the same area as the noise, so this could be what is destroying the glue of the case).

[Google Pixel 4a Guides, News, & Discussion] Spaceminer:
How to fix your creak!

I actually just stopped mine from creaking. Hopefully this will help a few other people. It seems like the backs aren't securely locked in place. This is what I did.

1. Place both thumbs on the screen over the creaky spot, with your pointer fingers behind them on the back panel and pinch.

2. Apply ~1lbs (sorry EU...) of pressure and slide your thumbs slightly towards the center of the screen, while pushing up on the back panel with your pointer fingers, towards the edge of your phone. The motion is exactly like rolling a cigarette. Release slightly, and repeat this until the creak stops.

3. You'll probably notice that your phone creaks somewhere else now. Pinch the spot that used to creak with one hand. Use the other hand to pinch the edge of the screen and back panel with ~1lbs of pressure, then slowly pinch your way around the border of the phone. Also 360 the border of the back camera. You should hear small clicks as the back panel locks into place. Repeat the border pinching process and the creaks should eventually stop.

4. Enjoy your much quieter Pixel 4a!

* If you only have one hand, then bring a friend.

** If you have no friends, then use your face or a stray cat.

*** If you have no hands or friends, then I don't have a solution.

Jokes aside, if this doesn't work for you then I'd suggest exchanging your phone.
