Guest Ygreck Posted March 2, 2013 Report Posted March 2, 2013 we have to change the base like zte blade with tpt this is hard to dev and can brick easiely
Guest hecatae Posted March 2, 2013 Report Posted March 2, 2013 change the cwm recovery fstab to recognise a new layout create a new cwm recovery with new layout flash it create roms with new layout flash them stock mount points # mount point fstype device [device2] fstype2 /recovery emmc /dev/block/mmcblk0p17 /boot emmc /dev/block/mmcblk0p9 /cache ext4 /dev/block/mmcblk0p16 /data ext4 /dev/block/mmcblk0p21 /emmc vfat /dev/block/mmcblk0p20 /sdcard vfat /dev/block/mmcblk1 /dev/block/mmcblk1p1 /system ext4 /dev/block/mmcblk0p14[/code] new mount points [code]# mount point fstype device [device2] fstype2 /recovery emmc /dev/block/mmcblk0p17 /boot emmc /dev/block/mmcblk0p9 /cache ext4 /dev/block/mmcblk0p16 /data ext4 /dev/block/mmcblk0p20 /emmc vfat /dev/block/mmcblk0p21 /sdcard vfat /dev/block/mmcblk1 /dev/block/mmcblk1p1 /system ext4 /dev/block/mmcblk0p14 only one change made, but would change data partition from 150mb to 1024mb.
Guest Ygreck Posted March 2, 2013 Report Posted March 2, 2013 okay, this was new for me! can you do that? is this save?
Guest bredwolf Posted March 3, 2013 Report Posted March 3, 2013 hmm,i don`t know to do that...Maybe one developer will read hecatae`s post and will do that,or maybe hecatae will do if he has some time:D.Thanks.
Guest hecatae Posted March 3, 2013 Report Posted March 3, 2013 okay, this was new for me! can you do that? is this save? I could do that but every cwm I've built you have tested for me never looked right.

Guest bredwolf Posted March 3, 2013 Report Posted March 3, 2013 so,yayakuya,you will try to do this?Please keep us at currency with all news,and when you need help please say:D.
Guest hecatae Posted March 3, 2013 Report Posted March 3, 2013 can i use this mount points on editing ramdisk? which file(s) should be edited? init.rc? you will need to repo sync cyanogenmod to build a new cwm, otherwise I can see problems
Guest SudeepDuhoon Posted March 8, 2013 Report Posted March 8, 2013 (edited) this is for the partition structure created to use with link2sd (ie fat, ext, fat32) REMOVE ALL SCRIPTS U ARE USING TO MOUNT EXT PARTITION AND MAKE A TITANIUM BACKUP OF ALL APPS extract init.rc of boot.img and edit it. do the following 1. search 'on fs' on fs comment out 'mount yaffs2 mtd@userdata /data nosuid nodev' with # like this # mount mtd partitions # Mount /system rw first to give the filesystem a chance to save a checkpoint mount yaffs2 mtd@system /system #mount yaffs2 mtd@system /system ro remount #mount yaffs2 mtd@userdata /data nosuid nodev mount yaffs2 mtd@persist /persist nosuid nodev mount yaffs2 mtd@cache /cache nosuid nodev mount yaffs2 mtd@persist /persist nosuid nodev now on 'on emmc-fs' replace wait /dev/block/mmcblk0p21 exec /system/bin/demigod_make_ext4fs -l 160M /dev/block/mmcblk0p21 /data exec /system/bin/e2fsck -y /dev/block/mmcblk0p21 mount ext4 /dev/block/mmcblk0p21 /data nosuid nodev noatime barrier=1 data=ordered noauto_da_alloc errors=continue with wait /dev/block/mmcblk1p2 wait /dev/block/mmcblk1p2 wait /dev/block/mmcblk1p2 exec /system/bin/demigod_make_ext4fs -e /dev/block/mmcblk1p2 /data exec /system/bin/e2fsck -y /dev/block/mmcblk1p2 mount ext4 /dev/block/mmcblk1p2 /data nosuid nodev noatime barrier=1 data=ordered noauto_da_alloc errors=continue save it pack the boot.img and flash it using cwm if u have any cwm flashable package with u then extract 'META-INF>com>google>android>updater-script' and edit it with notepad++ delete everithing it it and paste this run_program("/sbin/busybox", "mount", "/system"); package_extract_file("boot.img", "/tmp/boot.img"); assert(run_program("/system/bin/dd", "if=/tmp/boot.img", "of=/dev/block/mmcblk0p9")=="0"); run_program("/sbin/busybox", "umount", "/system"); save it and drag and drop it to it's location, i.e. 'META-INF>com>google>android> here' now drag and drop boot.img in the zip (no folder, the zip itself) make a nandroid backup and flash this. now, advance restore ONLY data using cwm recovery and reboot if you want to mount external sd as internal sd do this in int.rc (this may have bugs) search this #exec /system/bin/resize2fs /dev/block/mmcblk0p20 now remove all # from # [sTART] LGE_USE_INTERNAL_FAT #wait /dev/block/mmcblk0p20 #exec /system/bin/resize2fs /dev/block/mmcblk0p20 #exec /system/bin/e2fsck -y /dev/block/mmcblk0p20 #mount vfat /dev/block/mmcblk0p20 /mnt/sdcard # [END] LGE_USE_INTERNAL_FAT to make it like to like like this # [sTART] LGE_USE_INTERNAL_FAT wait /dev/block/mmcblk1p3 exec /system/bin/resize2fs /dev/block/mmcblk1p3 exec /system/bin/e2fsck -y /dev/block/mmcblk1p3 mount vfat /dev/block/mmcblk1p3 /mnt/sdcard # [END] LGE_USE_INTERNAL_FAT add this above "mount vfat /dev/block/mmcblk1p3 /mnt/sdcard" if not mounting unmount /dev/block/mmcblk0p20 save, pack, flash, enjoy. and no need to do anything with the recovery. your backup of data will be huge now. ;) Edited March 8, 2013 by SudeepDuhoon
Guest gellmar Posted March 9, 2013 Report Posted March 9, 2013 thanks for the info, will try to implement it too,especially with encryption ) By the way, anybody needs a flashable zip enabling ICS native encryption for us? I made a post in a big topic and can advance it with flash.
Guest Ygreck Posted March 9, 2013 Report Posted March 9, 2013 hm, maybe someone, but I'm not interested in the encryption make this sense? I mean, kernel 3.0 will came soon, and with that 4.1-4.2 will arrived and encryption is a main feature of jellybean... it woud be nice if you dev the ICS native encryption, but I don't want you to do something for nothing ;P
Guest gellmar Posted March 9, 2013 Report Posted March 9, 2013 (edited) Native ICS encryption works, and it fails only because CWM format full data partition not leaving the footer of 16KB, and due to one commented string in init.rc :) The chargerfix also uncomments it and a zip will contain a chargerfix bootimg and data repartition command I posted before. Do you ever know if Jelly Bean supports encrypting SD cards along with conventional data encryption? Edited March 9, 2013 by gellmar
Guest gellmar Posted March 9, 2013 Report Posted March 9, 2013 Dumped mmcblk0 partitions and tried to parse what is what -
