    Hello Ryogo,

    This seems to be very interesting, could you please still share some info with which FW should this work, have you tested on 10.1.0 or 11.2.x ? Based on your previous post I guess that if there is no difference in partition layout between the two, it would work on both, right ?

    Please rcommend if I can try on 10.1.0

    Thanks, Norbert

    I'm not sure what fw was used for testing, but I can find out if this is really crucial.
    Anyway, I compared partitions table on 10.1.0 and 11.2.3 - there are no differences.
    So, it should work regardless of FW version.

    Very good, I will try it out on my 2nd TVHD4 FW 10.1.0.

    Please allow still one perhaps silly question but I ask it anyway:
    Would this be a chance for those (like my sister) who unintentionally updated to FW 11.2.3 with Android 4.4.2 to go back like this:

    1. Someone creates Nandroid Backup with your TWRP on FW 10.1.0
    2. Then they install TWRP on their FR 11.2.3
    3. They restore backup taken on FW 10.1.0

    Please let me know your thoughts

    Thanks, Norbert

    Norbi24,
    actually, I'd rather suggest against using someone backup for downgrade.
    It should be possible to install modified vendor update.zip. I don't see a reason why this should not work.
    The only issue that may occur here is that uboot was updated during update to 11.x and it could be potentially not compatible with 10.x. And I'd better not downgrade u-boot since it may render device unusable if anything goes wrong with uboot.
    Anyway, I was going to try downgrade FW to 10.x a bit later so I could know for sure.
    Thanks Norbi24, kyôdai hat/haben sich bedankt

    Thanks to additional testing made by Waldy it is now clear now that TWRP currently boots only on 11.x fw.
    I'll be working on solving this issue soon.

    So, as far as I see - it is not possible to downgrade from 11.x to 10.x without downgrading u-boot.
    Also, I'm not really wiling trying to downgrade u-boot.

    It is already there: [Bitte einloggen oder registrieren um Links zu sehen.]
    Currently, I'm not tempted to try downgrading u-boot because in case anything goes wrong I would end up without working test device

    So, if anyone wants to take the risk for the sake of science - you're welcome

    Would you also publish the release build with improvements for FW 10.1.0 and issue with twrp boot if not connected with PC ?
    I currently am not able to build it but would like to try it out

    Thanks, Norbert

    Tolino 4HD
    What a coincidence, I've bricked my tolino 4HD (again lol), and it did not boot anymore, I was using 11.2 firmware and found the twrp in the original site. I was able to install the update.zip of the version 11.2.3 after modifiyng the updater-script (META-INF), before I do that I was getting the "error 7" during the update process. I was comming to post the twrp recovery here and it's already here! To me have worked fine, without it my device would still be bricked, now I have done a full twrp backup so I can restore easily.
    Thanks kyôdai, Waldy hat/haben sich bedankt

    So, I can confirm - I was able to downgrade from 11.2.3 to 10.1.0
    For this u-boot (bootloader), boot and system must be flashed.
    The issue is - you cannot install unmodified update.zip from vendor as it will not install u-boot.
