looks like my SGS2 corrupted it's /system and /data ext4 partitions so now they're read-only:
/dev/block/mmcblk0p9 /system ext4 ro,relatime,barrier=1,data=ordered 0 0
/dev/block/mmcblk0p10 /data ext4 ro,nosuid,nodev,noatime,barrier=1,data=ordered,noauto_da_alloc,discard 0 0
so now it's pretty much unusable.
how can I force fsck of those partitions or otherwise remount them as read-write?

Hmm ... let me guess ...
You have a real problem, if you want to keep the information in those partitions.
I would recommend to make a factory reset and flash the ROM you want to have with pit file and re-partion option in Odin.
Good luck !
I have same problem,
So there is no solutions at all?
What about booting into recovery then using a adb shell to run fsck on the partitions.
Note system is supposed to be read only but it couldn't hurt to check it.

Can some confirm if I understand correctly
As I understand internal GS2 memory is divided into several partitions:
/dev/block/mmcblk0p9 on /system type ext4
/dev/block/mmcblk0p7 on /cache type ext4
/dev/block/mmcblk0p1 on /efs type ext4
nil on /sys/kernel/debug type debugfs
/dev/block/mmcblk0p10 on /data type ext4
/dev/block/mmcblk0p4 on /mnt/.lfs type j4fs
/dev/block/vold/179:11 on /mnt/sdcard type vfat
So as I understand in CWM recovery:
format data formats dev/block/mmcblk0p10 on /data type ext4
format system formats /dev/block/mmcblk0p9 on /system type ext4
format cache formats /dev/block/mmcblk0p7 on /cache type ext4
wipe data / factory reset - on stock deletes everything from dir /data or just some files from dir /data
wipe cash - deletes all files from from /cache or just some files from dir /cache
wipe dalvik- deletes all files from from /data/dalvik-cache or just some files from dir /data/dalvik-cache
format /sdcard formats /dev/block/vold/179:11 on /mnt/sdcard type vfat ????
format /emmc formats what????
In what partition is bootloader?
In what partition is kernel?
In what partition is CWM recovery?
Where are located download mode (home+down+power) system/files?
From recent experience I understood that nandroid is not doing backup of all partitions. EFS partition is not backed up.
What else is not backed up and what partitions are backed up?
What partition is backed up in nandroid boot.img file?
Don't mess with them until you really know what you are doing
if bootloader gets messed up then its a brick
I really don't want to have problem and that's why I'm asking.
When you know simple basics it much safer to change ROM's
Well, if you'd search before asking questions, you'd have the information already.
Basically:
Code:
0 '/tmp' 'ramdisk' '(null)' '(null)' 0
1 '/efs' 'ext4' '/dev/block/mmcblk0p1' '(null)' 0
2 '/boot' 'emmc' '/dev/block/mmcblk0p2' '(null)' 0
3 '/recovery' 'emmc' '/dev/block/mmcblk0p6' '(null)' 0
4 '/cache' 'ext4' '/dev/block/mmcblk0p7' '(null)' 0
5 '/system' 'ext4' '/dev/block/mmcblk0p9' '(null)' 0
6 '/data' 'ext4' '/dev/block/mmcblk0p10' '(null)' -16384
7 '/preload' 'ext4' '/dev/block/mmcblk0p12' '(null)' 0
' 0 '/sdcard' 'vfat' '/dev/block/mmcblk1p1' '/dev/block/mmcblk1
9 '/sdcard1' 'vfat' '/dev/block/mmcblk0p11' '(null)' 0
Bootloader is in p2 and p3.
Kernel is in p5.
Recovery is inside the kernel.
Download mode (home+down+power) system/files is in initramfs (also kernel, basically).
Boot.img file contains the kernel if I remember correctly.
If you're concerned about partitions, back them all up with dd. However, be careful goes without saying
Sure I was looking, but short and simple answer couldn't find
Thanx
And additional questions:
So if /system (/dev/block/mmcblk0p9) is deleted, then phone still should be able to boot into download or recovery mode? (because Bootloader is in p2 and p3; Kernel is in p5.)
Can it be that in boot.img is packed p2, p3, p5 partitions?
/system comes with the ROM, so yes - you can delete it and still have recovery.
Why don't you extract the boot.img and see what's in it?
Sure I've tried to extract but..
In phone "Nandroid browser" can't open
In windows "unyaffs" says "broken image file"
In windows "DiskInternals Linux Reader" also not working
If you search you will find the post that shows how to extract on SGS2 and tools required .

i always formats system and boot in cwm 4.x.x but since 5.x.x only system is present, meaning formating boot is good but is more dangerous for all users to access.
formating system solves many issues.
this is a new idea,but not ok yet,just for suggest
(sorry for my poor english )
precondition:have root BEFORE update to r5a,(and NOT use ""double flash")
background:tablet s have 2 system partition,but only one is used.if your first system boot fail,system will try to boot use 2nd one
detail:
as precondition,you have root files in 2nd(backup) system,
so todo is try make system boot fail,then it will boot to backup system,
in backup system(have root) mount 1st partition and add root files
boot back to 1st system,
now you should have root
so how to make system boot fail(success flag not set)is the largest problem
my opinion is use reset button,break boot in right time.(near sony logo show)
and in more step, decompilation bin sysmount maybe get more info.
/init.nbx03.rc
Code:
on fs
wait /dev/block/mmcblk0p2
setprop ro.crypto.tmpfs_options size=128m,mode=0771,uid=1000,gid=1000
wait /dev/block/mmcblk0p3

mount ext4 /dev/block/mmcblk0p9 /log wait noatime nosuid nodev

Interesting, have you tried?
:good:

Hey guys, i have managed to root my Sony Tablet S (sgpt111gb/s) with the KingRoot app which you can download from the link below. You download APK on your device and install it as you would do normally and just run it and watch the show! I have to say that latest version of KingRoot DID NOT WORK with ver. 4.0.3 r5a currently installed on my tablet s but i've downloaded ''kingroot_global'' (link below) and it worked like a charm! My Sony Table S is now rooted
P.S. THIS ALSO WORKS FOR ALL OTHER ANDROID TABLETS/PHONES!
Link: kingroot dot net download or look for version 4.9.6_C151_B299....:fingers-crossed:
Hello all,
I'm new to the world of ROMS and custom recoveries, I've rooted my phone and for educational purposes, I wanted to build CWM 6 but I have trouble with my recovery.fstab or something because I only get a blank screen flashing periodically.
Here's the stock recovery.fstab of the recovery.img
Code:
/dev/block/platform/sprd-sdhci.0/mmcblk1p1 /sdcard vfat default recoveryonly
/dev/block/platform/sprd-sdhci.3/by-name/system /system ext4 default recoveryonly
/dev/block/platform/sprd-sdhci.3/by-name/HIDDEN /preload ext4 default recoveryonly
/dev/block/platform/sprd-sdhci.3/by-name/userdata /data ext4 default wait,length=-16384
/dev/block/platform/sprd-sdhci.3/by-name/CSC /cache ext4 default recoveryonly
/dev/block/platform/sprd-sdhci.3/by-name/efs /efs ext4 default recoveryonly
/dev/block/platform/sprd-sdhci.3/by-name/PRODNV /productinfo ext4 default recoveryonly
/dev/block/platform/sprd-sdhci.3/by-name/KERNEL /boot emmc default recoveryonly

/dev/block/platform/sprd-sdhci.3/by-name/modem /modem emmc default recoveryonly
/dev/block/platform/sprd-sdhci.3/by-name/DSP /modem2 emmc default recoveryonly
I've also tried this version (after changing the names with partitions)
Code:
# mount point fstype device
/system ext4 /dev/block/mmcblk0p18
/preload ext4 /dev/block/mmcblk0p19
/data ext4 /dev/block/mmcblk0p20
/cache ext4 /dev/block/mmcblk0p17
/efs ext4 /dev/block/mmcblk0p7
/productinfo ext4 /dev/block/mmcblk0p5

/modem emmc /dev/block/mmcblk0p13
/modem2 emmc /dev/block/mmcblk0p14
/sdcard vfat /dev/block/platform/sprd-sdhci.0/mmcblk1p1
but to no avail, the only result that I got was when I used the fstab of the boot.img
Code:
# Android fstab file.
# The filesystem that contains the filesystem checker binary (typically /system) cannot
# specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK

would you please tell me what I'm missing here ?
Just want to know
Could you tell me how you got root for this phone..? Been searching all over with no luck
This is my first time rooting and flashing custom rom. I think my phone's emmc is damaged because TWRP can't wipe or format data it says
Unable to mount /data/media/TWRP/ .twrp
Failed to mount '/3rdmodem' (Invalid argument) and so on
When I use this command cat /etc/fstab I get only this
/3rdmodem ext4 rw 0 0
/cache ext4 rw 0 0
/data f2fs rw 0 0
and so on
but I must be getting something like this
/dev/block/mmcblk0p13 /system ext4 rw 0 0
/dev/block/mmcblk0p14 /cache f2fs rw 0 0
/dev/block/mmcblk0p15 /data f2fs rw 0 0
this is missing /dev/block/mmcblkXXXX
and when I try this command
ls /dev/block/bootdevice/by-name/ or mount -t ext4 /dev/block/bootdevice/by-name/userdata /data
I get No such file or directory
Can someone please help me if my phone's emmc is damaged or not. If my phone's emmc is damaged than I will be wasting my time fixing my phone.
Thank you
Regards
Hi everybody
Currently i have attached a F1 to my pc which has some weird conditions...
The phone itself seems to be flashed to latest LineageOS, but it is encrypted.
Maybe because of the latest sideload, i can't really tell because the owner gave this to a friend...
So, prefered solution would be: decrypt the phone, get all the pictures/videos from it.
Another acceptable solution would be: install from scratch.
But:
fastboot seems to be botched.
Code:
C:\adb>adb devices
List of devices attached
22fd65f3 recovery
Looking good, adb can access this device.
So, if i could flash some decrypt-voodoo that the device boots and decrypts system...
But no, failing so far.
Then i thought, well, as it is already gone, just fastboot flash and forward.
Nope:
Code:
C:\adb>fastboot devices
???????????? fastboot
And the device goes back to bootloop.
Booting to recovery gives me a TWRP 3.5.2_10-0
Full access, except the encrypted data.
recovery is fully working, so i tried to flash vbmeta with fastboot (--disable-verity --disable-verification) but fastboot seems to be broken.
So... any thoughts where to start first?
Thx

If the phone doesn't recognize in fastboot you need the fix and the drivers.
You can find everything you need in my POCO F1 Ultimate Collection & Guides.
Check AMD/Intel Fastboot Fix.
If you know pin/pattern you can flash the TWRP by REIGNZ go to recovery put pin/pattern to decrypt then connect your device to pc while you are in twrp (if MTP doesn't work at first go advanced>file manager> and choose sdcard0 (internal storage) then your device shoule recognized in pc and get your data.
To clean flash follow my clean installation guide.
Everything you need is on my thread I mentioned above.
Okay, this is interesting...
My own Poco F1 had no issues with the drivers installed before.
After updating, the actual bugged F1 can fastboot but my own can't anymore.
WTF?
I also switched cables, doesn't matter.
Okay, nevertheless, mine is not broken, so this will be a task for later...
Thank you so far for this working hint!
So, i now finally have rescued all the pictures, videos and Whatsapp stuff.
My friend is happy.
The next step would be flashing the Pixel Experience.
But: how to find out which Android version is currently installed?
Or should i flash the latest stock rom from Xiaomi? I mean, it can't be higher than that, right?
Thank you for your response!
