How to unlock bootloader on d405n v20a ? - LG Optimus L90

Hi !
Didn't find the correct aboot.bin file for my device... Anyone help ?
My phone is already rooted...
Is there a way to manually dump the bootloader and patch it ?
Thanks,
Bruno.

Dump your aboot with:
Code:
dd if=/dev/block/platform/msm_sdcc.1/by-name/aboot of=/storage/external_SD/aboot.img
And post here.

write
PHP:
adb dd if=/system/hboot_7230ddr2_Runnymede_1.28.0006_20120424.nb0 of=/dev/block/mmcblk0p25
or
PHP:
adb shell
and than
PHP:
dd if=/system/hboot_7230ddr2_Runnymede_1.28.0006_20120424.nb0 of=/dev/block/mmcblk0p25
This operation does not break down your rom. All you have to do after this operation to change the file vold.fstab to 34 - This mean is nothing changing to your rom, no changes, no need reset factory etc. Only 1 what you need to do is change file called vold.fstab to see your sdcard on new hboot.
C:\Android>adb shell

where you find this patch? mmcblk0p25 - is /system folder
and your are trying to start it from this folder /data/local/tmp/ - its block 18
why i will get 'Operation not permitted'
when cmd
adb remount
basically, i have the problem on update to Hboot 1.28 by using your guide.
1. What we need to start:
- Unlocked bootloader (unlocked)
- S-OFF (ok... using FARDJADB method)
2. Download:
HBOOT 1.28 (PROBLEM)
Radio 3831.16.00.16_M (UPDATED)
3. Put the files in SDK Android Tools folder.

Which means i can use either way
dd if=/data/local/tmp/hboot_7230ddr2_Runnymede_1.28.0006_20120424.nb0 of=/dev/block/mmcblk0p18
or
dd if=/system/hboot_7230ddr2_Runnymede_1.28.0006_20120424.nb0 of=/dev/block/mmcblk0p25

How to backup a partition

How to backup - let's say boot - partition to a fastboot flashable file (*.img) format?
For example:
Code:
dd if=/dev/block/platform/hi_mci.0/by-name/boot of=/sdcard/boot.img
and so on.

Thanks. So fastboot is using dd images. Please do confirm.
Regards.
You can use only boot and recovery images extracted by dd for flashing via fastboot.

I have done the backup to the image file as you have suggested.
I have copied image file to the linux computer, but when I try to mount the image file I get:
mount -o loop boot_orig_B830.img /mnt/boot/
mount: /dev/loop0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
What is the file system for this image?
Length of the image file is:
ls -l boot_orig_B830.img
-rw-rw-r-- 1 test test 16777216 Lis 13 22:04 boot_orig_B830.img
For Linux: google "unpackbootimg", "gunzip" and "cpio".
For Windows: google "AndImgTool".

Request OEMinfo for Honor 5C (NEM-AL10/NEM-AL00)

Hi all,
Can someone please export and share oeminfo from Honor 5C(NEM-AL10/NEM-AL00)? It would be helpful for changing regions & flashing firmwares.
If rooted, you can easily dump oeminfo to the sdcard by the command :
Code:
adb shell su -c "dd if=/dev/block/platform/hi_mci.0/by-name/oeminfo of=/sdcard/oeminfo"
Thanks.
What U have firmware now?
