PostmarketOS rant / plea for help

feddit.uk/post/33980675

feddit.ukPostmarketOS rant / plea for help - Feddit UKHas anyone actually successfully installed PostmarketOS on an old device recently? I’ve had a long struggle through trying to prepare a Nexus 7 (2012) and the result seems to be a dead device before I even got to actually installing PostmarketOS. The rough steps I followed are listed here [https://wiki.postmarketos.org/wiki/Nvidia_Tegra_armv7_(nvidia-tegra-armv7)]: - Create backups [https://androidroot.github.io/pages/guides/tegra3-guide-nvflash-jellybean/] - Get SBK [https://gitlab.com/grate-driver/fusee-tools#dumping-sbk] - Build and prepare U-Boot [https://docs.u-boot.org/en/latest/board/asus/grouper.html] - Actually flashing U-Boot seems to be where things went wrong - Running ./run_bootloader.sh -s T30 -t ./bct/grouper.bct -b ../re-crypt/repart-block.bin or ./run_bootloader.sh -s T30 -t ./bct/grouper.bct -b ../generated-wheelie-blobs/AndroidRoot/blob.bin from fusee-tools hung on waiting for bootloader to initialize - Running ./run_bootloader.sh -s T30 -t ./bct/grouper.bct -b ../u-boot/u-boot-dtb-tegra.bin failed like this [https://xdaforums.com/t/trying-to-flash-uboot-on-2012-nexus7-grouper-failed-to-persist-efi-variables.4684381/] - skipping that step and running ./utils/nvflash_v1.13.87205 --resume --rawdevicewrite 0 1024 ../re-crypt/repart-block.bin hung on [resume mode] - Consulting a different version of the docs [https://docs.u-boot.org/en/v2024.04/board/asus/grouper_common.html] and running ./wheelie --blob ./generated-wheelie-blobs/AndroidRoot/blob.bin seemed to work so I ran ./nvflash --resume --rawdevicewrite 0 1024 ./re-crypt/repart-block.bin which also seemed to work - I then powered off as instructed and the device has been completely unresponsive since I’ve tried connecting to a charger, disconnecting and reconnecting the battery, and every combination of holding down buttons but it appears to be completely dead. Any suggestions as to what I did wrong or anything I might be able to do now? Obviously it’s not the end of the world to have lost a 13 year old tablet that was just gathering dust, but at the moment I’m not feeling positive about ever trying this again on another device!

Sometimes, I think... I just wish there was some sort of hardware that does X Y or Z, that would make things so much simpler...

Most recently, I was wishing for a #Serial adapter with a tiny screen, and sure enough...

... someone was listening... or thinking the same thing, but with more follow-through...

Very excited!

This would be very useful for the various #LinuxPhones or my #MNTReform ... which are just quirky enough to occasionally need portable serial access.

How to get started in postmarketOS?

Since for this project I am willing to spend money on a dedicated device, I don’t want to make a purchase I’ll regret because they decided to move on to a newer device (or disappear from the internet completely). > > I am not looking for a device with “perfect” support, as I feel like that would be useless. I want a device that works already well enough but that I can actually contribute with. > > My own Poco X3 NFC seems good for this, but I don’t think I want to commit my main smartphone yet. My older smartphone, the ASUS Zenfone 3 Laser, is completely unmentioned (but the base model is). Maybe I should simply use the latter and contribute by adding this extra device, or is it better to get something like a Google Pixel 3 or Motorola Moto G4 first?
