Yes I know. It worked out for me. I used Opengapps before, but the stopped at Android 10. Oh, I saw now that Android 11 is also available with Opengapps. So if you want to go safe take this one with platform ARM. Here is a link : https://opengapps.org/

Thanks.But this package seems outdated (15 Feb 2022) I will try nikgapps.My tablet lags very much in point i can't use it.Also when i flash pitchblack recovery from twrp (scorpion 3.0.2) it asks me to install as boot or system.But when i flash as boot,it desapears after next boot.Can i choose install to system?

Yes, I think it's not working with TWRP. I also using the pitchblack recovery. But honestly I'm not sure if you can flash it to system. I flashed it with adb.

 

[kos25k]

Yes, I think it's not working with TWRP. I also using the pitchblack recovery. But honestly I'm not sure if you can flash it to system. I flashed it with adb.

And it stays permanent?Which command u used?You mean u straighly installed pitchblack from cmd or twrp and then pitcblack?

 

[Max8719]

Yes ofc, it's the recovery. You have to install it with a computer with adb.
fastboot flash FOTAKernel should work

 

[kos25k]

thanks didn't know!So this command flashes all recoveries permanently?

 

[Max8719]

Yes it should. There many commands to flash a recovery. But you should search a bit in the web how to do it, if you are not so familiar with it....

I'm having problems booting my Z3TC WiFi SGP611 to recovery. Flashing recovery using `fastboot flash FOTAKernel pbrp_9.0_z3tcw.img` seems to work, but when I try to reboot to recovery the device boots into stock ROM. I have tried

• fastboot reboot recovery
• adb reboot recovery
• Pressing Volume down + Power buttons

Am I missing something basic?

EDIT:
I also tried flashing with `fastboot flash recovery...` rather than `fastboot flash FOTAKernel..`, but same result

First of all thanks to OP and all the contributors. I got this working after a several tries and very happy with it overall. I have a couple of issues so thanks in advance to anyone who can point me to the right direction...

First issue is display related, Chrome was acting up for some reason (black line on top and wasn't responding) but after several wipes and factory resets that seems to be fixed. The other display issue I am having at the moment is with Here We Go app which causes constant flickering.

Second issue is with Magisk, even though I followed the instructions (renaming modded apk to zip and installing it that way and I see the icon , when I click on it it says it needs to download something but fails...

Thank you very much again.


Edit: 5ghz not working for me also, tablet was bought from Amazon Germany Sgp621 model.

Anyone? I really would like to be running this ROM on my tablet, but without a functioning recovery it's not going to happen

Any clues how to make progress?

Thanks in anticipation

put the rom on sd card, fastboot flash FOTAKernel pbrp_9.0_z3tcw.img . boot to prbp install the rom then reboot. your system should be Lineage and the recovery should be TWRP.

 

[petefoth]

boot to prbp

OK I'm being really dense: how do i boot to prbw?

I've tried

fastboot reboot FOTAKernel

fastboot reboot recovery

fastboot boot FOTAKernel

fastboot boot pbrp_9.0_z3tcw.img

None of them work

Did you unlock your bootloader ?

Did you unlock your bootloader ?

Yes. I followed the instructions from the SOny Open Devices site. The unlock succeeded, the 'fastboot flash...` operations reported success, and the 'Configuration' screen from the Service Menu in the stock ROM says `Bootloader nlocked: Yes`

Yes. I've read the whole thread and now I am more confused. I have unlocked the bootloader successfully, I don;t want or need root. And I don't understand why that thread talks about flashing to the `boot` partition, when on other Sony devices (including Z3 and Z3 Compact) I normally flash the recovery image to the `recovery` partition, and your instructions use `FOTAKernel`. But I can leave finding out about all that until later

All I want at the moment is to know how to "boot pbrp"

I'm following your instructions, from earlier

put the rom on sd card, fastboot flash FOTAKernel pbrp_9.0_z3tcw.img . boot to prbp install the rom then reboot. your system should be Lineage and the recovery should be TWRP.

The bootloader is unlocked
`fastboot flash...` command worked,

$ fastboot flash FOTAKernel pbrp_9.0_z3tcw.img
Sending 'FOTAKernel' (14868 KB)                    OKAY [  0.575s]
Writing 'FOTAKernel'                               OKAY [  0.987s]
Finished. Total time: 1.575s

But none of the usual ways I know of booting to recovery work: they all end with the Stock ROM running

It has been a while since I worked with this tablet, but if I remember correctly the fastboot commands for rebooting into recovery don't work for this device. The button combination (power and either vol - or +) works but timing of releasing the buttons is key to boot into recovery. If you release too early or too late you boot into system instead. Also the original recovery may be restored if you reboot into system, so you must reflash the custom recovery first after you failed to boot into recovery.

 

[petefoth]

Thanks. I'll give that some more tries.

But now - after experimenting wth `fastboot flash...` and `fastboot boot..` commands, the device won;y boot into stock IT displays the blue 'wavy line' startup animation indefinitely

I think I need to reflash the stock firmware, if I can find it anywhere

 

[Pfrinz]

@petefoth You can flash it quite easy with Flashtool and Emma, thats what I did for some times now after running into the same issues as you...
Also for making sure to be on the latest stock ROM version.
None of the special issues or even button timing was necessary on the several SPG621 devices I successfully flashed, hmmm...
