e2fsck /dev/block/platform/msm_sdcc.1/by-name/persist
e2fsck 1.41.14 (22-Dec-2010)
/dev/block/platform/msm_sdcc.1/by-name/persist: recovering journal
Superblock needs_recovery flag is clear, but journal has data.
Run journal anyway<y>? y

e2fsck: unable to set superblock flags on /dev/block/platform/msm_sdcc.1/by-name/persist

also the "make" command is not working
anyone found the solution for this so far?

Hi evbdy,

My N5 can't register on any network. I tried to follow that guide to solve this supposing my persist partitions is broken (I may be wrong, I'm a newbie in this, I try many stuff to fix my phone, is there a way to be sure?)
But I have this result :
$ adb shell
id: unknown ID 2000
2000@hammerhead:/ $ su
root@hammerhead:/ # e2fsck /dev/block/platform/msm_sdcc.1/by-name/persist
e2fsck /dev/block/platform/msm_sdcc.1/by-name/persist
e2fsck 1.42.9 (28-Dec-2013)
e2fsck: Permission denied while trying to open /dev/block/platform/msm_sdcc.1/by-name/persist
You must have r/w access to the filesystem or be root
My phone is rooted, Android 6.0.1. Any idea?

Ok I'm an idiot, I wasn't in recovery...
$ adb shell
~ # e2fsck /dev/block/platform/msm_sdcc.1/by-name/persist
e2fsck /dev/block/platform/msm_sdcc.1/by-name/persist
e2fsck 1.42.9 (28-Dec-2013)
/dev/block/platform/msm_sdcc.1/by-name/persist: clean, 15/1024 files, 1109/4096 blocks
~ # make_ext4fs /dev/block/platform/msm_sdcc.1/by-name/persist
make_ext4fs /dev/block/platform/msm_sdcc.1/by-name/persist
Creating filesystem with parameters:
    Size: 16777216
    Block size: 4096
    Blocks per group: 32768
    Inodes per group: 1024
    Inode size: 256
    Journal blocks: 1024
    Blocks: 4096
    Block groups: 1
    Reserved block group size: 7
Created filesystem with 11/1024 inodes and 1102/4096 blocks
But it still not working, I can't access to any network...
Do you think it can be other than a software problem?
I can see networks when I look for them, but no way to register. I try with a SIM of a friend (other provider) and no more success.

When I enter "adb shell", it starts the daemon, and says "error: no devices found". Then I tried "e2fsck /dev/block/platform/msm_sdcc.1/by-name/persist", and it returned the good old "... is not recognized as an internal or external command, operable program or batch file.". I have android studio installed, and the command line I am using is opened at platform tools. Help?
