Hey
Currentrly i would like to analyze boostloader/download mode behavior and its internals. Coud someone help me to download bootloader binary ( or img or even some executable codes no matter ) from the i9300?
Through adb i didnt see any bootloader devices attached ( and that's right coz it already executed =D ) But i tried to locate it through
-adb shell
mount
Here is list of mounted devices:

PS:
Just to clarify:
I'm researching commands that are sent by ODIN to do its job. Also implemented heimdall-based sample that send "control codes" through libusb to the device. But without any success. ( found 0x68 command that was not used in heimdall, but device responses to it ). That's why i'm looking for a way to extract device's bootloader for short arm reverse engineering :fingers-crossed:

Did you find any solution? I'm having the same issue
Hello,
I'm using CyanogenMod 10.2 (on CM 10.1 that happened too) by Dazzozo.
My problem is, that apps can't access internal storage (File Explorer on Root permissions is able to). I've tried to reinstall system for a few times, formatting internal storage but nothing works.
I spent ab. 2 hours on studying google results, trying to understand what is wrong with this.
I don't know if this is helpful, but I've found, that when I will su on system/sdcard_rw I'm able to create/delete files and folders, but on default user at Terminal Emulator (u0_a44) I'm only able to read files and I can't create new ones or delete them.

hello,
i have two sch-r930 phones. (samsung galaxy s aviators) and through countless forums's and googling i cannot for the life of me find the recovery partitions, among others. even tho i have attempted all possibilities (the ones i found atleast) to find these, i ask others for assistance.
anything needed as far as output's from any commands or binaries can be provided.
help?
Looks like this might do the trick:
https://play.google.com/store/apps/details?id=com.cls.partition
or if you prefer to know how manually, then there might be some helpful info on this thread:

already attempted those. actually any app with partition in the title ive downloaded from the playstore and tried.
i have tried to ls -l /dev/block/platform and looked for a by-name in either location to no end. i have chekced the last_log from the cache/partition. i have used onandroid, romgen, romdump, flash_image, dump_image, etc to no end.
i need someone who can help me narrow it down by some other means.
is it possible that its wrapped up in with the kernel?

Hi all,
I have a Samsung Galaxy S4 (gt-i9505) on which I have Philz CWM Recovery and have install CyanogenMod 11.
I have two identical phones on which I have done exactly the same procedure (I thought!) to install the new ROM and recovery and one of them is perfectly fine whereas the other one is experiencing the following issue...
Everything has worked fine and the phone functions ok except while I was installing the ROM I found that I couldn't save anything to my external SD card. Now, since the ROM has been installed the external SD card is not accessible and attempting to mount it under the Storage menu says 'mounting ...' in the notification area but then doesn't nothing and the card is not mounted.
I assume I have done something to the permissions or symlinks when in the recovery but can't figure out what I did. I have inspected the file system of both phones via adb and the layout of folders and symlinks looks identical. The fstab.qcom and init.qcom.rc files also look identical.
When running the mount command on the phone with the SD card issue I get the following output:
Code:

How did I end up here?
1. Installed CM 12.1 Beta 4 from our friendly user forumber via TWRP
2. As GPS and camera didn't work, tried to get back to stock
3. Tried to flash 5 different roms (2 custom & 3 officials) but "error executing updater binary" just wouldn't let me
4. I don't know how but I finally managed to flash Yoigo stock one (Actualizacion_Blade_Vec_4G_Yoigo_V1.0.0B04.zip)
5. TWRP & Root went off. The entire internal memory is now on read-only memory.
Can't download a single file from the phone but somehow I can install apps via Play Store (pretty much the only thing I can do).
The only progress I made so far is to get root back again via Windows Kingroot.
Adb is working properly but mount command tells me operation not permitted
What should I do now? Replace Kingroot with Supersu? Change ro.secure parameter modding boot.img?
And most important: giving the circumstances, how could I do what you suggest me?
I should point out that I know nothing about programming and having got so far surprised me.
Thank you everybody in advance.
P.D. I don't know if the code I'll post will tell you something, but this is what cat /proc/mounts tells me:
