[Q] Problems while installing bootloader for KFHD7 - General Questions and Answers

Hello.
I wanna install CM 10.2 on my KFHD7. It's unofficialy suported and my friend did it. So i try install second bootloader from this tutorial. Everything went well. All hashes matched. But when i faced this
Code:
adb push stack /sdcard
i get error
Code:
$ ./stuff/adb push stack /sdcard
failed to copy 'stack' to '/sdcard': Is a directory
The file stack is in current directory and md5sum match (3cee2b7f3233fc3a1e10373677b8c1a9) and its' size is 4096 bytes and its' content is as follows
Code:
$ cat stack

And when I list directories on my KFHD7, i can see this file there size 4096 and same content.
So the question is is everything fine or I've made a mistake somewhere? If it's my fault, what is wrong?
Thanks beforehand.

[TOOL] rkflashtool for Linux and rk2808, rk2818 and rk2918 based tablets

Hi,
Because I don't run Windows nor NetBSD, I rewrote rkflash from scratch with the use of libusb-1.0, so you can now read and write your rk2818-based tablet's flash memory under Linux (also w/o the need to root your tablet). Credit for reverse-engineering the protocol goes to the original author of rkflash (see source).
Small guide
- unzip the file
- compile
Linux (Debian, Ubuntu, ...)
Code:
sudo apt-get install libusb-1.0-0-dev
gcc -o rkflashtool rkflashtool.c -lusb-1.0 -O2 -W -Wall -s
Mac OS X (thanks to surfer63, binary here)
Code:
sudo port install libusb
gcc -I/opt/local/include -I/opt/local/include/libusb-1.0 \
-L/opt/local/lib -o rkflashtool rkflashtool.c -lusb-1.0 -O2 -W -Wall
Preparation
- powerdown your tablet
- disconnect all cables
To get into flash mode differs for many tablets. Google around or use trial and error
- insert the USB cable in computer
- hold vol+ (or put on/off/locked-switch in the locked position)
- insert the other end of your cable in the tablet
- wait a few seconds
- release vol+
Now if you run lsusb, the following line should appear:
Bus 001 Device 044: ID 2207:281a (290a for rk2918 based tablets)
Bus and device number may be different. The screen of your tablet stays black.
The USB device must be readable and writable for the user running rkflashtool. If that's not the case, you'll see an error like this:
Code:
$ ./rkflashtool b
libusb couldn't open USB device /dev/bus/usb/001/048: Permission denied.
libusb requires write access to USB device nodes.
rkflashtool: fatal: cannot open device
This can be fixed in several ways (chmod, run as root, udev rules) but that's beyond the scope of this posting. For now, chmod 666 the device mentioned in the error message.
Usage of rkflashtool
Code:
$ ./rkflashtool
rkflashtool: fatal: usage:
rkflashtool b reboot device
rkflashtool r offset size >file read flash
rkflashtool w offset size <file write flash
offset and size are in units of 512 bytes
On my tablet, the boot partition starts at offset 0x8000 (in blocks of 512 bytes)
Its size is 0x2000 blocks
To backup the partition, issue:
Code:
$ ./rkflashtool r 0x8000 0x2000 >boot.img.backup
rkflashtool: info: interface claimed
rkflashtool: info: reading flash memory at offset 0x00008000
rkflashtool: info: reading flash memory at offset 0x00008020
.......
rkflashtool: info: reading flash memory at offset 0x00009fe0
To write a new boot.img or an old backup back to the device:
Code:
$ ./rkflashtool w 0x8000 0x2000 <boot.img.backup
rkflashtool: info: interface claimed
rkflashtool: info: writing flash memory at offset 0x00008000
rkflashtool: info: writing flash memory at offset 0x00008020
.......
rkflashtool: info: writing flash memory at offset 0x00009fe0
You can find a list of all partitions of your tablet in the HWDEF file, which is inside the update.img for your tablet. If no such file is available, you can also look at /proc/cmdline on a running device (either through adb or a terminal app running on the device itself). Depending on the tablet, you might need root access to view /proc/cmdline. Another option is dumping the first 0x2000 blocks of nand flash by issuing rkflashtool r 0x0000 0x2000 >parm. View the file with hexedit, xxd, or a similar program. The kernel parameters contain a description of several mtd partitions (sizes and offsets).
After reading and writing at will, you can reboot your tablet by issuing
./rkflashtool b
Note that if your tablet has an on/off/locked-switch and it is still in the locked position, rebooting won't work.
If the file you are writing is smaller than the specified size, the rest is padded with zeroes. If it's bigger, it will be truncated. This is different from rkflash, which will overwrite blocks beyond the partition size.
rkflashtool does not support flashing a new bootloader directly.
If you have a different tablet, please try rkflashtool b and r first before flashing (w) something new.
Standard DISCLAIMER with regard to bricking your tablet applies.
Enjoy!
EDIT: better build instructions, clean up text
EDIT2: works on rk2918 tablets too (tested on Arnova 7 G2) if you change the USB product id from 0x281a to 0x290a before compilation
EDIT3: released version 2 of rkflashtool. now supports rk2918 tablets out of the box. if it doesn't find one, it falls back to rk2808/rk2818. also, updated the wording a bit.
EDIT4: new mac osx binary
EDIT5: more ways to find offsets and sizes of partitions on your tablet
EDIT6: small emphasis changes above and...
version 1 is here ONLY for archival purposes or if version 2 does not work on your rk28xx tablet. In all other cases, you need to download rkflashtool-v2.zip
Thanks a lot for this flash tool. I'm on MacOSX and Ubuntu and don't have Windows either. I tried the original rkflash as well but couldn't get it to work. On my Ubuntu boxes your rkflashtool compiles and works fine.
My Archos 7 HT V2 presents itself also as:
Code:
Bus 002 Device 004: ID 2207:281a
Reading partitions works fine and so does writing.
I did a quick modification of a system.img (left some files out) of my custom froyo rom and wrote it to my tablet.
That works fine. As /data is a separate partition I even have all my downloaded apps, data, settings, etc. This makes modifying a new rom much faster then building a complete update.img, flashing it, restore some data and then start testing.
Nice work.
great! finally I can remove one line from my todo list
thank you!
EDIT:
random notes (I don't see your code yet so it may be fixed, then sorry)
* I always specify b(reboot) for rk2818 tablets with my rkflash because it hanged easily if I try to write multiple times without b
* parameter file need to be converted with rkcrc -p. official RKAndroid tools flashed it 5 times with offsets. (read & check 1st 0x0-0x2000 block)
* I logged how to update bootloader, but it's complicated and I could not understand probably bootloader can be updated via misc partition. see update-script in update.img. (but not recommended/no reason to do it)
EDIT2:
there is libusb for Windows and OS X. rkflashtool may work on them.
on Windows, there is RKAndroidTool.exe (not batchupgrade). but "read" function in rkflash/rkflashtool may be useful on some case on Windows
Good to hear it works for others, too! I have not had a hanging tablet after several writes in one session, but this might depend on the tablet.
Thanks for mentioning that it should also work on other platforms supported by libusb. I'd forgotten to do that.
About using update.img to flash a new bootloader, this can be done, but if you brick the tablet by flashing a wrong/faulty bootloader, you can only unbrick it with the Windows tools
Which leads me to the question: could you send me the snooped log of updating the bootloader? Two people see more than one and perhaps we can eventually manage to do this through libusb too.

probably you also need a needle to short pins of NAND chip
so I don't recommend to flash bootloader

I made that log several months ago with another windows machine which is not used lately. I'm not sure log is still exist... if I find it, I'll send it to you (but please don't expect)
probably you may also get log on Windows on VM on Linux. it seems VMware has log function (refer http://vusb-analyzer.sourceforge.net/tutorial.html) or there is "usbmon" function in Linux.
actually I didn't try this way myself so it may be wrong, sorry.
I've tryed a couple of firmwares, cooking my own.
Every time after flashing, tablet shows boot animation and after few seconds display becomes dark.
My investigation led me to following:
Log shows:
Code:
ERROR/Lights(865): write_int failed to open /sys/class/backlight/rk28_button_light/brightness
in /sys/class/backlight I found symlink (rk28_bl):
rk28_bl -> ../../devices/platform/rk28_backlight/backlight/rk28_bl
Shouldn't be there another symlink named r28_button_light ?
I'm using MANTA MID001 from Poland.

My main platform is OSX and I immediately added libusb. So far I have not been able to compile rkflashtool despite declaring all kind of CFLAGS, CXXFLAGS and/or LDFLAGS.
Trying a little bit more.
Could you post the compiler warnings/errors here? I might be able to help out.

I managed to compile it. It took a lot of hurdles. I used the build environment I also use for Hugin for which I'm the OSX maintainer.
I now built a single combined 32/64bit (i386/x86_64) rkflashtool that will run on 10.4.x/10.5.x/10.6.x/10.7.x (building multi-architecture, multi-version binaries/libraries in one binary/library is possible on OSX. I'm not going to explain that here but it's a feature of OSX).
The compiled version is attached. You can also attach it to your first post if you like.
It works fine. I did some reading/writing of images without issues.
If you are on OSX and have macports installed, you can do the following to build rkflashtool.
Install libusb from Macports:
Code:
sudo port install libusb
cd into the folder where your rkflashtool.c is is and run the following command:
Code:
gcc -I/opt/local/include -I/opt/local/include/libusb-1.0 \
-L/opt/local/lib -o rkflashtool rkflashtool.c -lusb-1.0 -W -Wall
This will build rkflashtool for your native environment (OSX version, hardware and config).
--- removed the rest of the post as well as the attachments. He/She who is interested in building a complete universal distributable rkflashtool can ask via this thread ---
UPDATE: Works on rk2918 tablet too
Yesterday I have tested the tool on an Arnova 7 G2 tablet, which has an rk2918 CPU. If you change the ProductID before compilation, like this:
... libusb_open_device_with_vid_pid(c, 0x2207, 0x281a) ...
to
... libusb_open_device_with_vid_pid(c, 0x2207, 0x290a) ...
it'll work, except for rebooting the device if the tablet is still locked. To boot the tablet in bootloader mode, turn off the tablet completely, put the on/off-switch in the locked position and connect it to your computer. It should be visible now with lsusb. For further instructions, see first post. I advise dumping the first 0x2000 blocks at offset 0x0000 first as this contains the parameter block in which you can see where each partition starts and how big it is.

Feature request :
I's nice but could you also make it a startup option, like the b,r,w options, with an if-else option in the source code? Something like (RK)2818 and (RK)2918 and maybe even for the older ones: (RK)2808.
In that case you only need one binary. Users who are going to use the tool will definitely know what CPU they have.

I released a new version and updated the first post. It now tries to connect to an rk2918 tablet and if it doesn't find one, it falls back to rk2818.
The V2 version works fine too on MacOSX. The compilation is still the same for a "my machine only" version.
I compiled a universal Intel 32bit/64bit 10.4/10.5/10.6/10.7 V2 version as well.
See attached.
Note: I don't have a RK2918 so I can only test for a RK2818 tablet.
Hi,
Thanks for your thread it's very intersting.
I succeed flashing my boot partition with your tool but I don't success in remount,rw my system partition. It's cramFS and in init.rk28board.rc you can see those line :
Code:
# Mount /system rw first to give the filesystem a chance to save a checkpoint
mount cramfs [email protected] /system
mount cramfs [email protected] /system ro remount
I tried everything like replacing ro by rw, deleting the second line but my system stills in ReadOnly, don't understand why. I also tried deleting those lines to test if my flash process works properly and it's worked... So I'm lost. Any idea ?
----
Other thing, if I want to do same as flashing boot partition but with system partition is it possible with the same process ? Unfortunately I don't know the beginning offset of the partition. I don't know where to find HWDEF file. The size of partition is 00038000 (hex) bytes => 229376 (dec) bytes
Here is my /proc/mtd :
Code:
dev: size erasesize name
mtd0: 00002000 00000010 "misc"
mtd1: 00004000 00000010 "kernel"
mtd2: 00002000 00000010 "boot"
mtd3: 00004000 00000010 "recovery"
mtd4: 00038000 00000010 "system"
mtd5: 0003a000 00000010 "backup"
mtd6: 0003a000 00000010 "cache"
mtd7: 00080000 00000010 "userdata"
mtd8: 00534000 00000010 "user"
mtd9: 00020000 00000010 "pagecache"
mtd10: 00020000 00000010 "swap"
Thank you for your great job
My problem is solved. I was searching for a while but ivop gave the answer in a previous post
I advise dumping the first 0x2000 blocks at offset 0x0000 first as this contains the parameter block in which you can see where each partition starts and how big it is.

So I did it, after I opened an Hex Editor like GHex on Ubuntu and I can saw this :
Code:
[email protected](misc),
[email protected](kernel),
[email protected](boot),
[email protected](recovery),
[email protected](system),
[email protected](backup),
[email protected](cache),
[email protected](userdata),
[email protected](user)
So system partition starts at E000 and has a length of 38000 (hex) bytes.
Thanks for your help this thread is now in my bookmarks
And really nice job with this flashtool
I pushed latest my rkutils to https://github.com/naobsd/rkutils
rkunpack can unpack RKFW image used in RK2918 ROM, RKAF image (update.img), KRNL/PARM image used in some single partition image. unpack will be done recursively.
rkcrc can make KRNL/PARM images with -k/-p.
rkafpack can make RKAF image. (I need to write docs/howtos...)
little off-topic,
latest RK2918 ROMs which is based on "SDK2.0", new format for boot.img/recovery.img is introduced. it's almost same as common boot.img format for android. unpackbootimg/mkbootimg can be used to unpack/repack it with one exception...
there is SHA1 hash value in header of boot.img (offset 0x240 bytes). Rockchip changes it by some unknown way. normal mkbootimg can't generate same hash value as Rockchip, so we can't make custom boot.img with new format
fortunately, we can split new boot.img, and we can make separate kernel.img and boot.img(ramdisk) like as pre-SDK2.0 RK2918 ROMs, which is loadable with new bootloader in SDK2.0 ROMs.

My problem is solved. I was searching for a while but ivop gave the answer in a previous post
So I did it, after I opened an Hex Editor like GHex on Ubuntu and I can saw this :
Code:
[email protected](misc),
[email protected](kernel),
[email protected](boot),
[email protected](recovery),
[email protected](system),
[email protected](backup),
[email protected](cache),
[email protected](userdata),
[email protected](user)
So system partition starts at E000 and has a length of 38000 (hex) bytes.
Thanks for your help this thread is now in my bookmarks
And really nice job with this flashtool

I'll add that to my first post. Also, you can view /proc/cmdline to see a list of partitions. It's part of the kernel command line.
Note that the lengths are not in bytes but in blocks of 512 bytes. This happens to be the same as the requirements of the rkflashtool btw (length in blocks).
As for having a writable system partition, currently the system partition is cramfs which cannot be written to. Ever. If you want a writable system partition, you need to change it to ext3 for example. That means unpacking fun_'s system.img and recreating it as an ext3 partition.
In short:
Unpack cramfs img with cramfsck -x (as root, so you preserve permissions and uid/gid)
Create an empty file the size of your system partition (dd if=/dev/null of=fubar.img bs=512 count=...... et cetera, do the math)
mkfs.ext3 fubar.img
mount -o loop fubar.img /someplacemountable
copy contents of old image to /someplacemountable (use cp -a to preserve ownership etc)
umount
flash fubar.img to system partition
change init.rk28board.rc to reflect the changes
reflash boot.img
reboot device
This is untested, but should work in theory.
Another option is to keep the system partition read-only and use unionfs to overlay a writable partition. I'm not sure if this can be a file on your userdata partition mounted with -o loop, but I suppose it can. This depends on your kernel having unionfs and loopback support though.

Broken Webtop

During the weekend, I was testing few things in the webtop using Debian packages and I needed to use my backup image (I did it using dd) to restore the Webtop partition (/dev/block/webtop). The first time I used my backup, everything went fine and the Webtop was restored. But then I understand my mistake in the first trial and tryed install gcc again causing another brake in webtop. After that I restored one more time, but it stopped working.
From the point of view of the Linux system, it seens the problem is that it can't mount correctly the partitions. A df give me:
Filesystem Size Used Available Use% Mounted on
rootfs 1.3G 724.6M 587.0M 55% /
tmpfs 1.3G 724.6M 587.0M 55% /dev
devpts 1.3G 724.6M 587.0M 55% /dev/pts
sysfs 1.3G 724.6M 587.0M 55% /sys

df: /mnt/sdcard/.android_secure: No such file or directory
df: /mnt/sdcard: No such file or directory
df: /mnt/asec/com.quoord.tapatalkxda.activity-1: No such file or directory
And when I mkdir /mnt/secure/ or /mnt/sdcard/ it automaticly mounts /dev/block/webtop on it.
I can't even see any block device inside the webtop. A ls /dev/ gives me:
agpgart kmem midi1 ram1 ram9 stdout
audio loop0 midi2 ram10 random tty
audio1 loop1 midi3 ram11 rmidi0 tty0
audio2 loop2 mixer ram12 rmidi1 tty1

dsp3 midi00 ptmx ram5 smpte3 tty9
fd midi01 pts ram6 sndstat urandom
full midi02 ram ram7 stderr xconsole
fuse midi03 ram0 ram8 stdin zero
And I can't mount any loop device.
In the Android part, everything looks fine.
Anyone have any idea?
Thank you very much!
Cheers,
Luis.
Well, we will need more information before we can be of much help.
1) How were you able install gcc? Did you use my webtop hack, so that you can install using synaptic?
2) Were are you installing these deb packages from?
3) Are you sure you edited ONLY parts in the webtop partition and not the android filesystem? Both of them run a form of linux, and can be confused very easily if you are in the wrong directory, such as /etc and not /osh/etc.
4) Have you tried to flash just the webtop image from the fxz?
This is a good place to start the questions, so that we can be of more help here. Once you answer the above, I will know which way to go from here, hopefully.

Thank you very much for your repply!
So,
1) I was not abble to install gcc from the repositories (from Ubuntu Maverick one). I always get an error installing the libc6. After I tracked the error to readlink it almost worked, I was only getting a error to move a file. But then I gave up and decided to wait for my sdcard arrive.
2) From the repositories. I tried the first time using Debian Squeeze repository and, after that, using Ubuntu Maverick one. I didn't use your hack because I was trying to learn what exactly brake compability with moto's packages.
3) That's a excelent question! In first place I really thought I was changing only the /osh partition, but I saw today that the /etc/ is actualy /osh/etc even for Android. So I changed things for Android too.
But in principle, this partition was restored when I dd it back to my backup.
4) No. Actualy I was looking for a FXZ image to do this. The only one I found Online was this: InlineFlashing_edison_5.5.175.16_cfc_p3_APBP_CID285.zip in Filefactory site, but I could not Download it yet due site limitations.
Thank you very much!

Ok, there are a few issues here.
1) try to restore the webtop image from the fxz. Go and grab the correct version of the fxz from here:
http://sbf.droid-developers.org/edison/list.php
Then unzip and cd into the directory and, make sure you have the moto-fastboot command, and that adb works:
Motofastboot:
32bit for windows:
https://dl.dropbox.com/u/45576654/moto-fastboot-win32.zip
put it somwhere in your path and open a command line and cd into the directory where you unzipped the fxz and run the following, this will take a bit of time to complete, once started (about 10 min):
Code:
adb reboot bootloader
moto-fastboot flash webtop grfs.img
moto-fastboot reboot
2) Now go run my hack, once you have your SDcard, the issue you ran into is that the webtop instance had MACLs and FACLs inplace, and any changes you make to ANY files can have a BAD effect. That is why my hack exists.

Still broken webtop
Hi,
I tried to unlock the webtop, but I broken it.
Now I try to flash back the webtop, but I get following messages:
C:\Program Files\sdk\platform-tools>moto-fastboot flash webtop grfs.img
load_file: could not allocate 1400635392 bytes
error: cannot load 'grfs.img'
Seems to me that the webtop partition is to small for grfs.img (only 1GB space)
At the moment even HDMI out from my ATRIX2 do not show any response. :crying:

I am using 2.3.6, systemversion 55.28.37.MB865.MERetail.en.06, Build 5.5.1-EDEM-28-37, and webtob WT-1.3.0-176. It is an ATT device.
I tryed the webtop image from
InlineFlashing_edison_5.5.175.25_cfc_p3_APBP.xml.zip
and
Returntostock2.3.5script.zip (edison-user 2.3.5 5.5.1-175_EDFFW1-16 5.51.175.16)
Both with the same error:

Perhaps both version should be wrong? Where can I find the right one?
I was able to flash webtop via RDS light 6.0 using following script in InlineFlashing_edison_5.5.175.25_cfc_p3_APBP.xml and ndp.xml

It seems flashing without any error message.
But it sill not working ... no HDMI signal ...
After all I have to use the "Returntostock2.3.5script.zip" and reinstall my "MERetail-MEARET-55.28.37.zip" ROM and all apps.
Now webtop works and I will do a backup BEFORE I will try webtop2sd again ...

[Q] Stuck in splash screen but CAN access recovery

I have tried over and over and many different ways to figure this out.... here is what's happening.
"power on" is stuck in splash screen and WILL NOT recognize on my PC as a device or in ADB
"power + vol down" grants me recovery mode which WILL recognize.
SD card will not mount to device. (i purchased brand new)
Cannot seem to push any files to internal storage... this is what my CMD looks like.

When I hit enter it does nothing but go to the space below and won't let me type anything.
I have tried PERI which didn't work because when it starts rebooting my device it just boots to the splash screen where it won't recognize on my PC
PLEASE any help I'm ripping my hair out here!

I do have the slider and would prefer to find help pertaining to that but it seems there are way more guides on the TF101 not SL101
It specifically says you cannot use the NVflash for sl101....

You can check the file /proc/mtd and /proc/mounts and upload it here, so I can see if we are dealing with the same problem. You can try to mount external sdcard.
While in ADB use:
Code:
adb pull /proc/mtd backup/
adb pull /proc/mounts backup/
This will copy this 2 files to folder backup.

OK, do you have busybox installed?
Can you post files: (-> adb pull... or you can insert external SDCARD and copy the files on it)
- /etc/fstab? -> here is written which partition is mounted as sdcard, system, data...
- /proc/partitions -> here are listed all the partitions that you have on the tablet.

I do not have busy box. and cannot install any new apps on tablet as far as I know... unless downloading on my computer will send it to my tablet? still wouldn't be able to open anything.
I'm a little confused about

should i write in cmd adb pull /etc/fstab/ ?
Sorry I feel like i need someone to hold my hand while i do this. I am so frustrated with the millions of different ways I've tried but it seems I have a very unique problem that doesn't have many helps vids/threads out there.

You can try, but without / at the end of fstab since fstab is not directory but file.
Code:
PULL usage: adb pull "file on tablet" "copy to remote machine"
adb pull /etc/fstab backup/fstab
adb pull /proc/partitions backup/partitions
If this doesn't work, you can insert micro SD in tablet and use adb shell to write linux commands.

OK, I see. This is only time needed for transfer.
Go to your folder, where you have got adb.exe (you can search with windows). There is created new folder backup, where you can find fstab and partitions. Upload the files or open them with notepad++ or regular notepad and paste the content of files here (it is the best to use #-tag in the editor of the post so the code is easier to read.)

OK thank you, I will analyse and compare the files with mine and from other TF's. But so far, I discovered, that TF's don't have special partition for data as on other Android devices and this probably causes problem.
For posting code, you can use [ CODE ] You write here code [ /CODE ] - write CODE in brackets without spaces. In post editor there is a sign # for indicating code.
You can try mounting /dev/block/mmcblk0p7 to a folder:
Code:
adb shell
mkdir NEW
mount /dev/block/mmcblk0p7 NEW
It probably won't work and this will indicate, that we are issuing the same problem.

Use commands as I wrote them:
This will connect to your tablet and access tablet's terminal commands
Code:
adb shell
You need to create new folder to which you will mount partition
Code:
mkdir /NEW
Now you only need to mount the partition
Code:
mount /dev/block/mmcblk0p7 /NEW
Did you have external sdcard attached, when you uploaded file partitions?

I don't remember partitioning the SD card. I did not have an SD card when I rooted.
I followed the code lines and it only came back as ~ #

[Q] Soft bricked tab (GT-P3100)

Hello guys I've run into a weird problem.
I installed SlimLP alpha builds, everything was fine. One day, after trying to format /system etc. before flashing latest version, the tab started rebooting itself every 20 seconds. I tried to uninstall some apps, when I rebooted the tab the apps were back. I booted back into CWM recovery and when I tried to flash old version of this rom, it just stuck at the start. Moreover, when I try to exit recovery it always says "Root access probably lost. Fix?" But that does nothing.
I went into Odin and tried flashing two different stock roms, but it gave error "Complete(Write) operation failed" at system.img .It displayed my model number as "i9505" I then tried to flash through old Odin(v1.75) and it worked. But when I rebooted, it went back into SlimLP. I tried flashing TWRP and latest cwm version but it went back to previous version. The "download count" in Download Mode remained constant. I tried formatting /system and /data through cwm. There was no error but tab still boots straight into SlimLP.
I then tried my luck with ADB in cwm by trying to change file permission. With "chmod 755 /system" it gave the error "Read-only file system" With "mount" , it gave error "Operation not permitted". I booted into slimlp, quickly enabled root for "apps and ADB" through developer options and tried the commands but same error.
I also tried "NAND wipe all" in Odin, but it stuck at "Erase...." and then gave error after sometime.
Is there a way to completely wipe the OS now so I can flash stock one through Odin?
Which recovery version of cwm you have? Probably it will be lower than 6.0.4.4
It is 6.0.4.5
If you're tab still boots then try installing twrp using app called rashr
Tab reboots after 20 seconds, can't install app in that duration.
I9505 means you flashed the wrong firmware to your tablet, I 9505 is an international S4 phone rom.
You need a new tablet.
Reading is very important when it comes to flashing your Samsung devices.

I downloaded the correct firmware from sammobile, checked many times. Also, I flashed from other Odin version, which didin't display any model number. I just checked Odin3, and even without the device connected, it displays i9505 at top.
EDIT: Well downloaded Odin3 from another site, It didn't show any model number. Guess "i9505" was just a title edit.
I think there is a big in cwm, there are many having this problem with that recovery, all Android andi about it, try sending private message to him, our some other developer
Thanks, I'll try that and post it here.
Please do the following:
Boot/try to boot system
Try to get a dmesg using adb
Boot into recovery
Use adb to pull last_kmesg
Please get a recovery.log after wiping.
Attach the files here.

I tried the commands like "adb shell dmesg > dmesg.txt" But got error "access is denied" Then I copied dmesg from console window, and pulled other files.

Can you upload the cwm you flash first and send me on pm?
Want to check if it's for our tab.
Will check your logs later.

Did you used rommanager for cwm?

Nope
Looks like a broken EMMC...
Please boot into recovery and use "adb shell":
Code:
adb shell mount -t ext4 /dev/block/mmcblk0p9 /system
if it mounts without problems do the same for data
Code:
adb shell mount -t ext4 /dev/block/mmcblk0p10 /data
Moutns without problem?
Please unmount now.
Code:
adb shell umount /system
adb shell umount /data
Let´s try to check the partitions now:
Code:
adb shell e2fsck -vf /dev/block/mmcblk0p9
adb shell e2fsck -vf /dev/block/mmcblk0p10
if you got error messages, please inform me.
Maybe we can reformat the partition by using adb shell.

It doesn't proceed, tried typing Y, Yes and all other keys.
Can you give me the output from:

Please from recovery and booting rom.
Have you tried flashing stockrom + pit file to repartition?

Sorry for the late reply, here are the files.
EDIT: I tried flashing the pit file with stock rom 2 times with Odin version 1.75, it flashed successfully but tab booted straight into SlimLP again.

[SOLVED] Restore build.prop to default: adb shell doesn't let me write

ROM: LineageOS 18.1, Recovery: LineageOS 18.1 recovery
I messed up and put my build.prop in an invalid state. I got the default build.prop from the rom zip,rebooted the phone to recovery (lineageos 18.1 recovery), mounted the system partition on /mnt/system, and tried to write build.prop to default via adb shell and then cat >/mnt/system/system/build.prop and writing whatever stuff I want. However, even after remounting as rw, I get the following error message:
Code:
cat: xwrite: No space left on device
The same thing happens if I just edit on my PC and do adb push
Code:
$ adb push build.prop /mnt/system/system/build.prop
build.prop: 1 file pushed, 0 skipped. 89.9 MB/s (2662 bytes in 0.000s)
adb: error: failed to copy 'build.prop' to '/mnt/system/system/build.prop': remote write failed: No space left on device
Now what does this even mean?? There is 3.1M free space, as confirmed by df -h. I really searched I cannot find anything on this. Any help would be really appreciated!
---
I can confirm it is mounted as rw by checking this line in /proc/mounts
Code:
/dev/block/dm-0 /mnt/system ext4 rw,seclabel,relatime 0 0
adb remount also fails with
/system/bin/sh: remount: inaccessible or not found
I'm at my wit's end, any guidance here? I feel this should really not be this difficult! I just want to rewrite build.prop from adb/recovery!
---
It might have something to do with overlayfs, as seen here https://android.googlesource.com/platform/system/core/+/master/fs_mgr/README.overlayfs.md. However adb remount merely says /system/bin/sh: remount: inaccessible or not found! How should I get this to work?
---
Finally: maybe I could just try to flash a zip containing only the build.prop via adb sideload? Will adb sideload wipe anything (e.g. system) or just overwrite the files which are present in the zip?
---
Just ended up flashing again. It worked without deleting apps or data
