Hi Martin

Thanks for your project. I've a problem with mit XZ2 (model H8216) and TWRP. I followed your instructions.

Installation of TWRP

[FASTBOOT] fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img <- IMPORTANT OR THE SYSTEM WON'T BOOT!

[FASTBOOT] fastboot boot twrp.img (Enter fastboot via adb, twrp, system, NOT via hardware buttons!)

[TWRP] Advanced menu -> "Install recovery ramdisk" -> Choose twrp.img

Reboot into installed TWRP

[TWRP] flash Magisk <- IMPORTANT OR THE SYSTEM WON'T BOOT!

Reboot into SYSTEM

(Optional) Switch SELinux to permissive <- Only if you really need it!

Reboot into installed TWRP

[TWRP] flash permissive.zip

Reboot into SYSTEM

Install the official Magisk App to gain root.

I'll paste my Linux terminal code and the names of the files I used.

root@Tim:/home/tim/Schreibtisch/platform-tools# ./fastboot boot /home/tim/Schreibtisch/twrp/twrp-xz2.img

I used "2019-04-24_14-09-06_sony_stock_twrp_xz2_52.0.A.8.25.tar.gz". Also step 3 is working. Temporally flashed TWRP and the TWRP button "Install recovery ramdisk" with file "twrp-xz2.img" from "2019-04-24_14-09-06_sony_stock_twrp_xz2_52.0.A.8.25.tar.gz" seems to work.

With step 4 I started into the installed TWRP permanently. The phone reboots and shows the TWRP boot screen for a part of a second. The display becomes blag a few seconds. Then the TWRP boot boot screen appears a part of a second. Endless flickering of TWRP boot screen. I can't use TWRP this wise. I don't see the TWRP buttons. I saw a button in TWRP, "fix TWRP bootloop" or similar. It doesn't helped. On my phone I installed the last stock ROM, "H8216_Customized+CH_1313-2246_52.0.A.3.84_R2B.tar.gz" Edit: Sorry, I flashed "H8216_52.0.A.8.25_1313-2246_R3B.ftf"

Hallo Tim,

the issue occur if the security patch version of the firmware is too old.

The encryption process won't work due to the roll back protection by google in AvB 2.0

Please flash and boot the newest stock rom from april first, please.

Viele Grüße

Martin
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Katzenstreu:
Hallo Martin :)

My fault! I flashed with Xperia Flashing Tool 0.9.25.0 with XperiFirm the image "H8216_52.0.A.8.25_1313-2246_R3B.ftf" . See attachment. It's too old?

Lieben Gruß

Tim
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Does it works now?

Because you said "On my phone I installed the last stock ROM, "H8216_Customized+CH_1313-2246_52.0.A.3.84_R2B.tar.gz""

:)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Katzenstreu:
No, does not worked. In my upper was an error. I wrote the wrong file name. I flashed H8216_52.0.A.8.25_1313-2246_R3B.ftf and then I followed your instructions.

Your failure analysis seems not to be correct. Is seems to be another reason.

I crossed-out the wrong information in the upper post. Sorry!
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Weird.

Could you try to fastboot boot twrp and install magisk 18.1 and reinstall the ramdisk?

Did you modify the bootimage before?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Katzenstreu:
Now I tried the following:

2. [FASTBOOT] fastboot boot twrp.img

Skipped: 3. [TWRP] Advanced menu -> "Install recovery ramdisk" -> Choose twrp.img

Skipped: 4. Reboot into installed TWRP

5. [TWRP] flash Magisk <- IMPORTANT OR THE SYSTEM WON'T BOOT!

6. Reboot into SYSTEM

I went with step 2 into temporallly falshed TWRP.

I dind't installed it again via step 3.

I flashed via temporally flashed TWRP MAGISK 18.1. Successfully.

I rebooted into permanently flashed TWRP. Same issue. Flickering TWRP boot screen.

I didn't modified the bootimage before. It was a clean Xperia Flash Tool with file "H8216_52.0.A.8.25_1313-2246_R3B.ftf".

Edit/Added: Should I use another ftf-file? Not the "H8216_52.0.A.8.25_1313-2246_R3B.ftf" from Switzerland? Which release you are using in/for Germany?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] dhacke:
I always flash the german version of the stock rom. Here the twrp (version for custom roms because i use OmniROM) works on my side (Xperia XZ2 Dual Sim).
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Hmm, could you reflash the ramdisk in fastboot boot twrp and then install magisk before restarting into recovery?

I also never flashed ftf files.

I download the firmware via xperifirm and flash it via newflasher (Both on XDA)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Hmm, the region shouldn't matter, specially on the aosp release where I can't choose a region for the aosp kernel. :)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Katzenstreu:
Another try: I flashed the German Telekom version successfully: "H8216_52.0.A.8.25_1313-9026_R4B.ftf". Downloaded via XperiFirm and flashed via Sony Moile Flasher/Xperia Flashing Tool 0.9.25.0. Now my console log:

TWRP (temp) started.

I pressed the TWRP "Advanced" button.

I clicked on "install recovery ramdisk" and choosed "twrp-xz2.img" from "2019-04-24_14-09-06_sony_stock_twrp_xz2_52.0.A.8.25.tar.gz"

I tried the critical step 4 again: Reboot into bootloader. TWRP is starting in TWRP bootloop/flickering.

After that I tried your advice: reflashed ramdisk and instantly Magisk 18.1. Same Issue. Flickering TWRP.

1. What I should do with the file "twrp-stock-installer-xz2.zip, which i fould also in "2019-04-24_14-09-06_sony_stock_twrp_xz2_52.0.A.8.25.tar.gz"?

2. Should I try your [ROM][AOSP][XZ2, XZ2C, XZ3] SonyAOSP 9.0_r35 [Stable]?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Katzenstreu:
Now I gave your [ROM][AOSP][XZ2, XZ2C, XZ3] SonyAOSP 9.0_r35 [Stable] a try. I installed it like you wrote, but first without gapps. Successful.

The system started normally. I folowd the known instruction:

1. [FASTBOOT] fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img <- IMPORTANT OR THE SYSTEM WON'T BOOT!
2. [FASTBOOT] fastboot boot twrp.img (Enter fastboot via adb, twrp, system, NOT via hardware buttons!)

I repeated the step 1. (I think we did it while installing your

In step 2 boot.img was successfully sended in 2 seconds. Booting was measured with 5 seconds. But (temporally) TWRP isn't starting. The screen keeps black, the LED is glowing blue. This is another failure.

This time I used vbmeta.img and twrp.img from "2019-04-24_16-08-30_sony_custom_rom_twrp_xz2.tar.gz".

It's really hard to install TWRP and your custom ROM. The update process isn't easier, either? I only want to use a stable ROM with Magisk. I can't see my failure.

---------- Post added at 05:04 PM ---------- Previous post was at 04:54 PM ----------

It's not correct to flash first your AOSP release and then trying to install TWRP? Is TWRP included in your AOSP release?

I started your recovery. "Android Recovery" and there I found your name, Martin.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
At the moment I have no time to look how to create a installer.zip to flash all of the partitions with it in twrp (except the OEM binaries of course). :)

Which fastboot version do you use?

./fastboot --version
fastboot version 28.0.1-4986621

This version or a bigger one works.

And also what's your bootloader version?

fastboot getvar all

bootloader version v118 is needed.

(Please censor the serial numbers in your output)

And did you wait a bit while the screen was black?

Sometimes it takes a bit time to show the twrp logo.

On my XZ2 it worked flawlessy.

Maybe you need to flash the stock firmware with newflasher v13 and not a ftf file.

And please first flash the aosp/custom rom dtbo.img before fastboot boot twrp.img or it won't work.

dtbo and twrp need to match.

And I can't include twrp with my roms.

The roms need to build as a -userdebug build, while twrp needs to get build as a -eng build.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Are you sure you're using the right twrp?

The installer.zip was removed since I fixed "fastboot boot twrp.img"
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Your logs are looking fine.

If I remember correctly, I had problems with other tools than newflasher and the twrp last year.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Katzenstreu:
I think this was the failure! I installed an old version of twrp.img with fastboot-TWRP from an old directory on my phone. That was't your curstom-rom TWRP.

Sorry! This was my fault. I was a little bit overchallenged:

Flashing a fresh stock ROM.

Flashing a custom ROM in many img parts.

Flashing some files again for TWRP. And the choosing of the files is subjected to the previous constellation.

Do you offer an instruction for updating your custom ROM? Or should we repeat all steps (without "fastboot flash userdata userdata.img")?

Best regards

Tim
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Yes, at the moment you need to reflash every single IMG file. But not the userdata.img if you don't want to wipe your phone :)

And niiice that it works now :D
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Katzenstreu:
I'm so happy! Thanks a lot, Martin! Great project!

Now I'll test your ROM :).
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Thank you very much :)

Nice to hear :D

[MENTION=6031898]MartinX3[/MENTION] - Anybody successfully installed Magisk 19 yet? There's quite a bit of info on the changelog, and hordes of users in Magisk thread who are getting errors/problems, but I don't understand much of it... Also, do you know what would be the cause of "...too many symlinks" error in terminal in recovery? It doesn't happen after initially installing recovery, but only after installing Magisk.

Thanks
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Hingbong:
use fastboot to flash omni from aosp, get into twrp ,all things in my internal storage can't be read

after reboot times, it is ok
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
19.1 is like russian roulette.

If you have luck, it works.

I heard from someone that a fullwipe fixed his problem too.

I wouldn't update to 19.1.

And 19.0 drained more battery on my device.

"...too many symlinks" do I only get with twrp because of the new system-as-root

the root is at /system, the real system is at /system/system

means, that if a symlink in /bin want to symlink on /system/bin, it symlinks on itself instead and that results in a loop where each loop run count as one symlink and of course this looping let the symlink limit explode.

I'll investigate + test further for a fix in my next free time.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] levone1:
I wondered about that /system/system thing... Also, I had a situation where I flashed a Magisk module that wrote an apk to /system/app, and it worked fine, but then I wanted to customize it, so I made a modified apk with apktool, and signed it, but I couldn't get it to copy to the app folder. It would always copy about half the size of the apk, and end with an error. I tried to copy it in terminal, and I got 'no space left... ' error. So, I went into recovery, to copy it there, and the app folder was not visible in /system/app. I rebooted, and there it was... I guess I need to relearn everything I thought I knew about Android system...

[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] FcukBloat:
hi [MENTION=6031898]MartinX3[/MENTION] long time no see. can I ask you one question: with unlocked BL, it is not possible to boot up the phone without magisk, correct? (of course with sony stock fw, oreo or pie)

and BL can not be relocked, right?

because I gave my xz2c to my brother, and he can't use his banking app because he finds the root. I am working to find the way to hide root, but if I can't, I am trying to find alternatives, like removing root etc

tia!
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Hellooo [MENTION=4695495]FcukBloat[/MENTION]

umh, I didn't test it for a long time, you could try it.

Anyway you can reinstall magisk in twrp.

or you can play with magisk hide to fix his banking account :)

Yes, sadly we can't relock the bootloader, even not for personal enterprise purpose with own certificates.

tiaaaaaaa!
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] FcukBloat:
thanks for the answer! on the phone I left oreo and drmfix, so without root, even if it could boot, I think it can't install permissive module, so drm fix won't work... in this case, without drmfix, I could also install pie... but it is crucial to see if phone can still boot without magisk... OK if I can't hide root in any way, i will try removing completely magisk... hope phone can boot but I don't think so because also in your OP you say "[TWRP] flash Magisk <- IMPORTANT OR THE SYSTEM WON'T BOOT!"... thanks! ;)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Yes, that was definitely the Oreo case, maybe PIE too.

I didn't had time to test it again, so I left it there, better than 100 users asking why their device bootloops. :P
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] aragorn771:
After Magisk 19.1 boot looped my phone, I went and flashed the regular boot.img and then re-rooted my phone. It worked fine for a little over 24 hours but now my phone is back in boot loop and installing the kernel isn't doing anything.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Please stay at 18.1 until a 19.2 or 19.3 comes with the right fixes.

19.1 is borked.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] aragorn771:
I did go back to 18.1 but my phone was only good for 24 hours...Now I have re-installed the rom, wiping my user data, and am re-installing backups as I type. Hopefully I am good...
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
So you did "fastboot flash boot boot.img" and didn't install a magisk and it still bootlooped?

Because I did (with omnirom)

install magisk 18.1 on my system without magisk

reboot into system

install magisk 19.1

boot into system (i had luck, no bootloop with 19.1)

fastboot flash boot boot.img

reboot into system

And the system was fine.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Seems like monthly twrp's are still important.

"fastboot boot twrp.img" works, but if the security patch date doesn't match, I am stuck at the twrp logo.

Even if I set the ro.build.version.security_patch to 3019-04-05 in the prop.default.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] aragorn771:
Yes. I am on stock rom. Fastboot flash boot boot.img then re-installed twrp, vbmeta, magisk 18.1.

Originally when I did this on Sunday night, all was fine. But it just started bootlooping out of nowhere this morning and doing the above wouldn't stop it this time.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Did you use newflasher or another tool to flash the bootimage?

Then you need to reapply the vbmeta parameters. (I think it is still important)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] aragorn771:
Newflasher and I do VBmeta
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
The omnirom looped me too on a fresh wiped system because I installed magisk before the very first boot of the system.

I needed to boot it once before flashing magisk 18.1.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] aragorn771:
did a reboot first as well....
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
but i lost my userdata too, due to the rollback protection (my may build needs a newer prebuild kernel from may and doesn't work correctly)

so I need to use my google backup and the "migrate" backup.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] HowTIZ:
xperifix.com is down, is it the end of the service?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Not sure, maybe a server issue (at the provider).

I lost the contact to him since the surgery accident of his girlfriend.

In the end I or any other with the binary could extract the drmfix out of the xperifix.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Try first the newest (april) stock firmware or maybe march comes now, and unlock your phone.

On PIE only the low light camera anti noise algorithms may not work.

Xperifix still exists, it was only a server failure.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] VeixES:
Anyone got xz3 dual 8.25 fw patched boot img with magisk 19 or older?

Or any other ideas how I could get 8.25 build rooted again?

seems when I tried to go back to the 3.202 I get corrupted android msg on boot. maybe that could be resolved?

Firmware Update

After I used the OREO firmware with TWRP all originally from the androidpit-link from from first post of this thread, with Magisk 19.1 and enabled permissive mode by using the Magisk SELinux Manager Module, now the "Xperia System-Update" shows me that an update to firmware version 52.0.A.8.50 was available. I suppose that I can not just tap "update" and everything is fine. :D Because... which components won't work anymore If I was doing so? And which steps should I perform in order to "update" to that offered version? Is it possible at all? My thoughts were the following:

Create a backup of almost all partitions with TWRP - for the case of "disaster"

Create App+Data backups with Titanium Backup - also for the case of "disaster"

Create a backup of phone data (contacts/phonebook...) because there where some former issues resoring them with Titanium Backup

Find and download a firmware image file of the version 52.0.A.8.50

Remove the userdata.sin from the firmware files

Flash the firmware with NewFlasher

(Maybe?) disable the verification again with the vbmeta.img file with "fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img"

Reboot to system and pray :eek:

Please let me know if this was the right way, or if there are steps missing, or if I could even simply tap "update"? :laugh: Also: Is another update of TWRP needed?

Thank you for every answer.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] levone1:
Definitely don't forget the 'pray' part... I think you're on the right track - do as much as possible, and something might work. Personally, (I have XZ2c), TWRP has not been able to restore data for me, (extractfork process error - known current bug), so I'm not in a rush to mess with it just for a new security patch. Maybe when / if a major update comes I'll spend some effort on it...

I was thinking if I really wanted to be sure, I could do a dd dump of userdata, and flash it back w/ fastboot, but I guess even that might have issues, depending on what's in the update.

Command would be

dd if=/dev/block/sda73 of=/sdcard/userdata.img

then you get a file in your storage that you can flash with fastboot to restore data.

Note:

- The img file might be very large

- Your userdata partition might not be sda73. Check it with

ls -al /dev/block/platform/soc/1d84000.ufshc/by-name
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Harry500:
Thanks for your reply. What whould you consider to be a major update? The currently installed OREO-firmware is (from the original post) version 51.1.A.11.51. The version suggested by "Xperia System-Update" is 52.0.A.8.50, just recognized that this was PIE. So this would also mean some more trouble concerning the camera issues. Would it be possible to perform an update to some latest OREO version instead?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] levone1:
I didn't realize that you were still on O. I have Pie, and the last update came yesterday, and was just a security patch, so I probably won't bother for now. I'm using eXistenZ rom, with Magisk, MicroG, EdXposed, and several other mods, so lots of chance to break something with an update. I probably wouldn't bother trying, unless it was a pretty significant update, (especially since TWRP hasn't been dependable).
[MENTION=6031898]MartinX3[/MENTION] has instructions in his Pie recovery thread about dealing with camera issues from O to P. Wasn't an issue for me, since I didn't unlock bootloader until I was on latest Pie, and Sony made it so that unlocking bootloader doesn't break camera anymore, (but still lose a couple of ta-based features)...
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Harry500:
Ok. :good: Is the "Pie recovery thread" that you mentioned this monster thread that we are currently writing on, or is there a seperate one for people who want to migrate from O to P? :) Maybe I should check again if this was an option...
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] levone1:
Oh yeah, sorry - I didn't even realize what thread we were on... This thread, first post, (screen shot).
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] Harry500:
Ok, thanks for this. But as far as I do understand that linked thread, it was not an option for me to update to PIE as I already unlocked my bootloader with OREO firmware installed. I would struggle into these described problems with the camera, wouldn't I?
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
Please flash your bootimage again

A fresh flashed 19.1 generates a corrupted error.
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
You need to fix the camera with xperifix in Oreo first. :)
[Sony Xperia XZ2 ROMs, Kernels, Recoveries, & Other] MartinX3:
I need to release a stock twrp each month.

Even with "fastboot boot twrp.img" we still can't use a twrp from last month correctly (google rollback protection; stuck at twrp logo, because decryption fails; the security date must match).

Same for the aosp twrp (there I need to wait for a new precompiled kernel with the llvm clang changes, they are tested and working, this also stops also my new ROM builds).

Actual probably a breaking bug
