Progress
What's been done:
- device-htc-vision builds
- linux-htc-vision builds (using milaq's kernel)
- device boots
Cmdrwgls created pull request !810 with his work. This work was later finished by mberndt in pmaports!132.
Installation Notes
Obviously you need an unlocked bootloader; refer to [1] for instructions about that. S-OFF is not needed.
Installing the rootfs using fastboot doesn't work due to size limitations in the bootloader, therefore if you want to install postmarketOS to the internal memory, do an Android Recovery Zip Installation. postmarketOS is picky when it comes to the recovery. It works with CWM 6.0.5.0, see [2]. It does not work with CWM 6.0.4.5 or TWRP 2.6.3.0.
Next steps
- test more hardware: audio, camera, radio, bluetooth…
- probably more firmware blobs are needed to get some of these working
Partition layout
Note that the practical partitions are small. The mmcblk0p25 (system) is 558M, mmcblk0p26 (data) is 1.1G.
For some reason fdisk -l shows overlapping entries. The first 29 partitions seem to be the real ones.
$ fdisk -l /dev/mmcblk0 Omitting partitions after #60. They will be deleted if you save this partition table. Disk /dev/mmcblk0: 2.1 GiB, 2256535552 bytes, 4407296 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x00000000 Device Boot Start End Sectors Size Id Type /dev/mmcblk0p1 * 1 1000 1000 500K 4d QNX4.x /dev/mmcblk0p2 1001 1128 128 64K 45 unknown /dev/mmcblk0p3 1129 10128 9000 4.4M 46 unknown /dev/mmcblk0p4 10129 4407294 4397166 2.1G 5 Extended /dev/mmcblk0p5 10130 70129 60000 29.3M 49 unknown /dev/mmcblk0p6 70131 95130 25000 12.2M 50 OnTrack DM /dev/mmcblk0p7 95132 99227 4096 2M 51 OnTrack DM6 Aux1 /dev/mmcblk0p8 99229 105372 6144 3M 52 CP/M /dev/mmcblk0p9 105374 109469 4096 2M 53 OnTrack DM6 Aux3 /dev/mmcblk0p10 109471 111518 2048 1M 54 OnTrackDM6 /dev/mmcblk0p11 111520 113567 2048 1M 56 Golden Bow /dev/mmcblk0p12 113569 131071 17503 8.5M 55 EZ-Drive /dev/mmcblk0p13 131073 137216 6144 3M 4a unknown /dev/mmcblk0p14 137218 143361 6144 3M 4b unknown /dev/mmcblk0p15 143363 145410 2048 1M 74 unknown /dev/mmcblk0p16 145412 163326 17915 8.7M 75 PC/IX /dev/mmcblk0p17 163328 163839 512 256K 76 unknown /dev/mmcblk0p18 163841 165888 2048 1M 47 unknown /dev/mmcblk0p19 165890 167937 2048 1M 34 unknown /dev/mmcblk0p20 167939 170498 2560 1.3M 36 unknown /dev/mmcblk0p21 170500 187901 17402 8.5M 71 unknown /dev/mmcblk0p22 187903 196094 8192 4M 48 unknown /dev/mmcblk0p23 196096 196607 512 256K 73 unknown /dev/mmcblk0p24 196609 200702 4094 2M 26 unknown /dev/mmcblk0p25 200704 1343486 1142783 558M 83 Linux /dev/mmcblk0p26 1343488 3577854 2234367 1.1G 83 Linux /dev/mmcblk0p27 3577856 4192254 614399 300M 83 Linux /dev/mmcblk0p28 4192256 4234750 42495 20.7M 19 unknown /dev/mmcblk0p29 4234752 4235263 512 256K 23 unknown /dev/mmcblk0p30 10130 70129 60000 29.3M 49 unknown /dev/mmcblk0p31 70131 95130 25000 12.2M 50 OnTrack DM /dev/mmcblk0p32 95132 99227 4096 2M 51 OnTrack DM6 Aux1 /dev/mmcblk0p33 99229 105372 6144 3M 52 CP/M /dev/mmcblk0p34 105374 109469 4096 2M 53 OnTrack DM6 Aux3 /dev/mmcblk0p35 109471 111518 2048 1M 54 OnTrackDM6 /dev/mmcblk0p36 111520 113567 2048 1M 56 Golden Bow /dev/mmcblk0p37 113569 131071 17503 8.5M 55 EZ-Drive /dev/mmcblk0p38 131073 137216 6144 3M 4a unknown /dev/mmcblk0p39 137218 143361 6144 3M 4b unknown /dev/mmcblk0p40 143363 145410 2048 1M 74 unknown /dev/mmcblk0p41 145412 163326 17915 8.7M 75 PC/IX /dev/mmcblk0p42 163328 163839 512 256K 76 unknown /dev/mmcblk0p43 163841 165888 2048 1M 47 unknown /dev/mmcblk0p44 165890 167937 2048 1M 34 unknown /dev/mmcblk0p45 167939 170498 2560 1.3M 36 unknown /dev/mmcblk0p46 170500 187901 17402 8.5M 71 unknown /dev/mmcblk0p47 187903 196094 8192 4M 48 unknown /dev/mmcblk0p48 196096 196607 512 256K 73 unknown /dev/mmcblk0p49 196609 200702 4094 2M 26 unknown /dev/mmcblk0p50 200704 1343486 1142783 558M 83 Linux /dev/mmcblk0p51 1343488 3577854 2234367 1.1G 83 Linux /dev/mmcblk0p52 3577856 4192254 614399 300M 83 Linux /dev/mmcblk0p53 4192256 4234750 42495 20.7M 19 unknown /dev/mmcblk0p54 4234752 4235263 512 256K 23 unknown /dev/mmcblk0p55 10130 70129 60000 29.3M 49 unknown /dev/mmcblk0p56 70131 95130 25000 12.2M 50 OnTrack DM /dev/mmcblk0p57 95132 99227 4096 2M 51 OnTrack DM6 Aux1 /dev/mmcblk0p58 99229 105372 6144 3M 52 CP/M /dev/mmcblk0p59 105374 109469 4096 2M 53 OnTrack DM6 Aux3 /dev/mmcblk0p60 109471 111518 2048 1M 54 OnTrackDM6 Partition table entries are not in disk order.
