I got it guys but I had to downgrade to lineage 18.1 2021-09-11 version. I do not know the change logs from the two versions but there should not be any major difference, I guess.

This build is now also available on the LineageOS build and download server. Does this mean we get now also builds from https://lineage.microg.org/ after some time ?

Was there a reason that this build was not available on LinageOS servers?

Yes.

The reason was simply that I did not have the LTE model myself, it probably was ready for a long time already.
Now haggertk got one, so thanks to him it's official now.

Thank you and also @haggertk for you effort and work. I‘m just bought this device because there was this LineageOS build by you guys. Thanks a lot!

I have a Motorola 9609 Samsung device and LineageOS has no signal, seems to be a modem aspect

Hi OP, ive now updated my wife's tablet from Lineage18.0, to this version lineage-18.1-20211010-UNOFFICIAL-gta4xlwifi.zip. Also managed to update and remove TWRP and install Lineage Recovery.

Obvious question but need to ask it. Now when I go on the tablet to update, it says my version Lineage 18.1, and there is a new version 19.1 (16/04/2022). Can I confirm I am NOT to attempt download this version, as the latest version for unofficial is 18.1 10/10/2021?

Well, I have to say that you haven't updated your wife's device in a long time, I would recommend a clean install to the latest versions You can migrate app data when you are booted with migrate app.


Of course you can also switch from unofficial to the official lineage

Haha yes, I have been bit slack on updates for her but at the same time it has been working fine for all this time.

From what I understand by OP, its not recommended to dirty flash from Unofficial to Official (hence why I didnt install the official). I wanted to minimise the least amount of disruption i.e. not installing her large apps. And considering i'm going from 18.0 unofficial, to 18.1 unofficial I felt it would have been no major issues with the dirty flash.

I just need some clarification about the 19.1 version, if you got some comment on this. Thank you.

I think I answered my own question going to https://forum.xda-developers.com/t/...os-19-1-for-galaxy-tab-s6-lite.4348847/page-4

The Answer is, I am not to do the install as it technically would mean I'm doing a dirty flash from Android 11 to Android 12.
Will leave the version as is for my wife for the moment.

Hi everyone,

for a customer project we have created a custom build of LineageOS 18.1 for SM-P610 and I have an image that is complete with our signage software.
I used to be able to flash these devices following the official installation instructions from the LineageOS page https://web.archive.org/web/20211002124915/https://wiki.lineageos.org/devices/gta4xlwifi/install

Now this doesn't work anymore. On some devices, I can't even unlock the bootloader. This has been discussed elsewhere and I have tried all the tricks from manipulating the datetime to logging on with a google or even a samsung account.
But even on the devices where I could onlock OEM, I can't seem to install the LineageOS recovery. I always get the error message "Only official released binaries are allowed to be flashed (RECOVERY)". FAP LOCK is OFF and OEM LOCK is OFF(U).

It says in the LineageOS install instructions that I must have the latest official Android 11 firmware installed. Previously, I would simply OTA update to this firmware, but nowadays, OTA goes directly to Android 12. So I tried downloading the only available Android 11 firmware from sammobile and flashing it in Heimdall. But unfortunately, I still get the same error message.

Can anybody please tell me which version of the Samsung bootloader I need exactly to install this version of the LineageOS recovery: lineage-18.1-20220112-recovery-gta4xlwifi.img?
Bonus question: Does anybody still have this firmware version mirrored somewhere?

edit: I have downloaded a newer recovery from the internet archives: lineage-18.1-20220504-recovery-gta4xlwifi.img
Now a get a different error message: "Custom binary(RECOVERY) blocked due to remaining installment balance".
Can somebody tell me what this means?

Update: I have found what seems to be the exact Samsung firmware that was the latest one at the time:

https://samfrew.com/de/download/Galaxy__Tab__S6__Lite__-Wi-Fi-__/0kd5/DBT/P610XXU2DUL9/P610OXM2DUL9/

I'm currently downloading.
Also, I have been able to bring one of the really old devices to exactly this firmware state by OTA by cycling through 3 consecutive incremental updates. I was pretty excited to bring it into download mode, only to see this strange error "Custom binary(RECOVERY) blocked due to remaining installment balance" yet again.

I don't know if this is the case, but there were Samsung tablets that were sold on installment plans. These devices had special bootloaders that required the seller to unlock once the last installment payment was made.

I highly doubt this was the case here. The devices are from a stockpile of retail demo devices. Other devices from suposedly the same sockpile were working just fine earlier this year.

Why else would there be a "remaining installment balance"? You don't think a retailer would have some that were demo versions and some returned "installment" ones?
