Strange partitions on nexus 7
-
I bought a Nexus 7 on eBay that was broken and did not boot. Android recovery didn't work but Ubuntu touch fortunately installed without problems.
At the first analysis the hard disk is formatted in a strange way.Disk /dev/loop0: 2 GiB, 2097152000 bytes, 4096000 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 Disk /dev/loop1: 120,9 MiB, 126738432 bytes, 247536 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 Disk /dev/mmcblk0: 28,8 GiB, 30937186304 bytes, 60424192 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: gpt Disk identifier: 98101B32-BBE2-4BF2-A06E-2BB33D000C20 Device Start End Sectors Size Type /dev/mmcblk0p1 131072 306143 175072 85,5M Microsoft basic data /dev/mmcblk0p2 393216 399359 6144 3M unknown /dev/mmcblk0p3 399360 405503 6144 3M unknown /dev/mmcblk0p4 524288 554287 30000 14,7M Linux filesystem /dev/mmcblk0p5 655360 656919 1560 780K unknown /dev/mmcblk0p6 656920 658479 1560 780K unknown /dev/mmcblk0p7 786432 787991 1560 780K unknown /dev/mmcblk0p8 787992 794135 6144 3M unknown /dev/mmcblk0p9 917504 920503 3000 1,5M unknown /dev/mmcblk0p10 920504 923503 3000 1,5M unknown /dev/mmcblk0p11 923504 927599 4096 2M unknown /dev/mmcblk0p12 927600 937839 10240 5M unknown /dev/mmcblk0p13 937840 938863 1024 512K unknown /dev/mmcblk0p14 1048576 1081343 32768 16M unknown /dev/mmcblk0p15 1179648 1180671 1024 512K unknown /dev/mmcblk0p16 1180672 1180673 2 1K unknown /dev/mmcblk0p17 1180674 1183673 3000 1,5M unknown /dev/mmcblk0p18 1183674 1187769 4096 2M unknown /dev/mmcblk0p19 1187770 1198009 10240 5M unknown /dev/mmcblk0p20 1198010 1199033 1024 512K unknown /dev/mmcblk0p21 1199034 1200057 1024 512K unknown /dev/mmcblk0p22 1310720 3031039 1720320 840M Linux filesystem /dev/mmcblk0p23 3031040 4177919 1146880 560M Linux filesystem /dev/mmcblk0p24 4194304 4196351 2048 1M unknown /dev/mmcblk0p25 4325376 4345855 20480 10M unknown /dev/mmcblk0p26 4456448 4456463 16 8K unknown /dev/mmcblk0p27 4456464 4456479 16 8K unknown /dev/mmcblk0p28 4456480 4456481 2 1K unknown /dev/mmcblk0p29 4587520 4587583 64 32K unknown /dev/mmcblk0p30 4718592 60424158 55705567 26,6G Linux filesystem
Do I have a possibility to correct this

@kultex nexus 7 needed for installing Lineage 9 (8 also?) and forks of it a repartition. So maybe it has been repartitioned with a modified Twrp for that reason. In that case, it may help to partitionate with a former twrp that does not partitionate. (I do not know which version.)

Sorry i have no android experience....you mean i install twrp and delete there partitions and reinstall ubuntu touch?
Something like gparted is not available in ubuntu touch?

@eichenbast I just found a thread, that this 30 partitions are very normal in android???
https://forum.xda-developers.com/nexus-7-2013/general/guide-repartition-nexus72013-to-t3599907I guess UBports is using only p1 for recovery and p30 for the rest - everything else is unused from UBports??
So I guess I dont need twrp - I boot into UBports recovery and run from the PC
adb push parted / adb shell ~ # chmod +x parted ~ # /parted /dev/block/mmcblk0
??? and delete all partitions exept p1 ????
and my next question - is there a possibility for dual boot with postmarket os? I think, UBports is more advanced, but I am more familiar with Alpine Linux than with ubuntu...

@kultex said in Strange partitions on nexus 7:
??? and delete all partitions exept p1 ????
No. This will break the system. Don't delete partitions at random. It won'get get you more space, and will break the system.
and my next question - is there a possibility for dual boot with postmarket os? I think, UBports is more advanced, but I am more familiar with Alpine Linux than with ubuntu...
No, dual boot is not supported by Ubuntu Touch on any devices.

@kultex So looks the partitions on Pinephone https://forums.ubports.com/topic/4950/pinephone-as-a-daily-driver-test-report?_=1605342465632.
Multiboot works on Pinephone only.
