Almost no empty space

Hey!
I'm having a problem with my Note 3 which is getting pretty annoying.
After doing a clean install I only got about 2gb left on my 32gb phone, it tells me theres 21gb in miscellaneous files, but if I enter to see what it is, theres almost nothing there.
I read another thread about the same issue and he got an answer which told him that the other files probably were hidden on the phone and only accessible via a root explorer, which I have.
The problem is that I don't really know what files belong there anymore and which files should be gone.
The Note is running X-Note 20.0

[Discussion] An alternative for Tab 2 emmc bug & brick backup

Well, I have been going through many tab owner problems on this forum who have tried everything on the book to get their tab back running. this experimental process is only for those people who have no option left than to throw away their tab as a dead glorious paperweight or play with it as a Frisbee. hopefully it can recover or at least it can open a new way for getting out of a brick or perhaps be a good learning experience, just for the sake of it. what else would you want to do? if your device is un-repairable? at least this can take a backup for the complete device in a different way though.
So what really is this about?
Well, Samsung tab 2 emmc is pretty much notoriously getting scarier, either it is happening because of flashing a wrong kernel or doing wrong with your tab, or in some cases where people had no clue. A sudden attack and the tab was dead. you may be lucky to get a replacement and get the tab running up again. but not all could be solved and resolved.
but what if we provide the tab a second emmc(your external card emulated and working as an exact image of the internal emmc with all the system files with their partition on it?) sounds good eh? there are 2 sides of this coin. one, our device is not made that way and it's definitely not going to work at all, second, it can work after a little hardware modification provided you have the right files and right tools and a insanely expert brain. Now the chances of this working is like that of flipped coin landing on it's edges. very tricky.
But how we can achieve this then?
Well, there are users on the internet that have some sort of success in this, while it wasn't guaranteed for their device, that this process can work for all and there is definitely nothing like this sort ever found for our device. which is on omap chipset, it's the debrick method. you can't tell unless you are from the development department of Samsung. So, I would say even if it's 0.0000000001 percent of having a chance to work for us. I would like to keep it.
Debrick.img? what does it do? how to get it?
Well, this file is generally taken out from a stock rom from location /dev/block/mmcblk0 which is where pit stores the data for all the partition and from there we can extract all the important parts, including the boot-loader, recovery, cache, hidden, sbl1, sbl2, factoryfs param, modem, EFS, DataEFS to a .img file. (as far as my definition goes for better understanding). please feel free to go through all the post that you can find about the debrick, or if you have more knowledge please share.
I was just going through these posts.
The whole process for sg s3 http://forum.xda-developers.com/showthread.php?t=2660566
http://forum.xda-developers.com/showthread.php?t=1818321 a guide that explains about taking backup of the entire memory block with all partitions or single partition. it's quite old but informative.
fixing a bootloader
http://forum.xda-developers.com/showthread.php?t=2345860
there are different parts to it, first is getting the bootloader written on a external sd card. but we still don't know if our device will be able to treat the external sd card as an internal emmc. it is yet to be found out.
my theory is suppose if we can get out the whole partition along with system written on a external card, can we make the device treat it as a internal emmc? will it then be possible to revive a dead internal emmc tab? there are chances it might. still no practical though and no guarantees for sure.
but it makes you feel better, I managed to get out those partition on a .img file which could be written on a external card as well. basically an image of your emmc. this might be a good backup too for those who would like to be safe in case a emmc bug hits them too.
Now, To get this data we need volunteers to take these files from their working rooted stock rom and upload these files for every model of samsung tab, if they wish to contribute to our community, you are welcome. or at least keep it safe on their disks. although, this process will require atmost care as we are dealing with bootloaders here, and one wrong bootloder and it
won't work, as much as my knowledge goes, there are two- the ics and jb for our tab 2. still there are many other variants and I really have no clue, how to work this out all by myself. so, I would like other great minds share their wisdom upon this and please before sharing files, mention everything you can, right from your
1. Device model number
2. 8gb or 16gb
3. Bootloader(ics or jb)
4. Stock rom, custom rom,
5. firmware
6. Baseband
7. Country and to your name.
Now before pulling out this file, I have a doubt, as I have got few imgs option. there is 128mb, 200mb, 256mb, 512mb and also I have got one img of around 2.17gb as well which is the complete backup I could take out from my device.
I am not sure which one to choose that's going to work. people have mostly used 128mb file to get access to the download mode, I guess in that 128mb, there is enough files needed to boot your device into download mode and recover from hard bricks, but there is no evidence as for now in our device section as to which is suffient for us. So for first try, we take 128mb, and keep doubt aside for one process.
but suppose it's our emmc bug and we want to use the external as a image of the damaged internal, in that case I suppose we need to take out the whole info! is it really possible with the 2.17gb of my device complete data? ah, I would really like to know about the answer myself, in case it hits my device, I would be prepared myself
anyways to try this you must have a sd card reader and use a external card of 16gb or 8gb depending upon your device variant (card class 10 required, on others it has high chance of not working at all)
Now the process to extract the file
The script that you need to enter into terminal emulator(download one from playstore) this will backup a 128mb file on your sdcard.
Code:
#su
#busybox dd if=/dev/block/mmcblk0 of=/sdcard/debrick.img bs=1M count=128
128MB is arbitrary. on some devices 70MB was sufficient, on our device? maybe or maybe not. please test or help me answer this correctly, if I'm wrong. but untill then, use 128mb, if we fail, we will look for other options.
other dd commands
Code:
1. dd if=/dev/block/mmcblk0 of=/sdcard/backup.img
backup whole partitons thus will be large size and takes more time.
Code:
2. dd if=/dev/block/mmcblk0 of=/sdcard/debrick.img bs=1M count=70
70mb data from mmcblk0 will be copied to sd card
Code:
3 dd if=/dev/block/mmcblk0 of=/sdcard/debrick.img bs=1M count=512
512mb data from mmcblk0 will be copied to sd card
Code:
4. dd if=/dev/block/mmcblk0 of=/sdcard/backup.img bs=4096
large size more than 4GB and more time consuming
Procedure
1. Connect the external sd card to the card reader move all the files to your pc and format it.
2. find the correct debrick.img image from post 2.
3. Download and extract this software win iso burner
4. Open the software win32diskimager.exe and browse the debrick.img
5. Successfully Write the debrick.img onto it.
6. Put the sdcard in your device
7. Pray, or do the cha cha, praise the droid lord.
8. switch it on or press power button + volume down/up, whatever you can.
9. if you can then get into download mode, you can try to flash stock firmware or dance your way around.
10. report us back what happened.​

So, you're one of those lucky ones. Getting a replacement is still the best way. So, do you think my theory here could work? Anyways it would be an interesting answer to find out. But people would need to share files here first for any samsung tab 2 model. I hope it becomes helpful rather than just interesting.

Well I still haven't faced the emmc bug, so can't really test on my device yet. nobody else who faced this issue had tried this and posted or shared any of the findings here.

Updating the emmc firmware via. ISP gives back life to >80% of affected devices.
16 GB Tab 2 have a known faulty EMMC (MAG2GA). It can happen, that your EMMC get "read only", so you can't perform any write actions (also you can't format) anymore.
From the EMMC data sheet:
5.1.7 End of Life Management:
The end of device life time is defined when there is no more available reserved block for bad block management in the device. When the device reaches to end of its life time, device shall change its state to permanent write protection state. In this case, write operation is not allowed any more but read operation are still allowed.
But, reliability of the operation can not be guaranteed after end of life.

On a faulty EMMC firmware it happens a lot faster if the emmc reaches a wrong value.
Sadly Patching the emmc fw isn't possible running the device, at least there's no known kernel on chip power-on Method...
Those from europe can contact @html6405 , he is able to update the emmc firmware and he can also replace the emmc if needed.
Note:
Sharing a whole copy if mmcblk0 isn't good, because it will include efs partition which is sensible data.

Found something interesting printing the pit using heimdall:

Someone knows what the GANG partition is for?
I wonder if it is the emmc firmware because emmc.bin is stored there...
I am waiting to get the fixed emmc firmware, i might be able to tell you once i have it.

Yes, better to keep them private. Users do not share, just keep a backup with yourself.
thanks for your thorough research.

I did notice the GANG partition since you mentioned it(strange I never realized this before as I have looked at the pit file many times earlier as well.) located at 0x64C.
it does look like the emmc firmware partition. what else it should have?

Look at this on eBay http://www.ebay.com/itm/192025936615
Sent from my SAMSUNG-SM-G870A using XDA Free mobile app

Hi,
I just tried this method. The tab boot on the sdcard, i have the charging logo displayed, and then screen turns black. The driver change from omap4430 to Android, and keep this driver until i unplug the usb cable.
On linux, the tab device is recognized as Android. Same on windows (loaded in virtualbox from linux).
adb device display an unauthorized device.
So from this step, it is still impossible to flash the tab.
Anyway thanks for sharing this; even if its painfull to lose a tab, it is nice to learn how all this work.
if other people have more information to share, i would appreciate any new info on this subject

LG G2 802 still uses 10.77 GB instead of 25 GB

Hello together, I'm searching for a solution since a few days now and i tried many things but none of them fixed my problem.
I got a problem that some of you may had before as well. I once tried to flash LineAgeOS on my LG G2 D802 but it was unsucessful. After i flashed back on Stock Rom i realized that i now just got 10 GB free space, instead of 25 GB. The Phone even shows i got 32 GB but System-Data folder got 21.5 GB.
I tried it with the following instruction: I tried it using the xbin folder, because i wasnt able to copy the files into the bin folder, eventhough i got root access.
[url]https://forum.xda-developers.com/showthread.php?t=2470207&page=1[/URL]
Anyway, when i use the command print it first showed on line 36 the 15,7 GB. I did all the other commands, then did a CSE-Flash with D80230D_00.kdz. After that i did a Hard-Reset but my phone did not show the 25 GB free Space.
I tried it again and when i used the print command, it now shows that i got 32 GB on line 36. Anyway did again the CSE-Flash with the same file (which i downloaded from LG due to my IMEI number, so it should defenitly be the right kdz), i did a factory reset again but still no 32 GB.
I don't know whats the problem here. Could it be, that i have to do a normal flash instead of CSE-Flash? Could it be that the CSE-Flash deletes the files in /system/xbin but i need them still for the Factory Reset? Or does a Flash genrally delets all the /system/xbin files?
If anybody got a solution here, i would be very happy, 10 GB is way to less for me

Is there noone with the same issues?

i have the same problem as i can see that there is 21G for system and i cannot find the files which should be deleted

Try to search your phone (the kdz for it) here
http://storagecow.eu/index.php?dir=Xda/LG+G2/Stock/
download the kdz. If i download "Lollipop" "32GB" and then flashing my Land kdz "Germany D80230b.kdz" it shows normally 24gb of my 32gb.
Probably youre flashing 16gb Kdz. try the 32gb one
I hope i could help :good:

So I just found that my Mi5s has eMMC 5.1 instead of UFS 2.0

After a year of usage I've run ROM benchmark which resulted in 230MB read and 118MB write (sequential ofc). I also found (and lost) thread on MIUI site. There was a table that compared storage speeds. This results are almost perfect match for eMMC 5.1. also "cat /proc/scsi/scsi" command reported that I have "Toshiba thglf2g9j8lbatrh" memory chip. I could not find it on Toshiba site neither in eMMC section, nor in UFS.
I have a silver 3/64 version, probably one of the first ones, bought it on "11th of November" a year ago.
So go ahead check your devices. Please, let me know what results you will get.

I'm getting 433MB/s read, 131MB/s write (both sequential). Bought my phone in April 2017 and still running Nougat.

Can you please run the command from OP? It requires root though. You can execute it from PC using ADB: you would have to download it if you have not already, then add "ADB shell su " before the command from OP and execute it from command line. You can also do it from device itself: download some terminal app, add just "su " to the command and run it

Same here eMMC on my device, and I bought it in 06.2017... But I am not power user, so I don't care

Sure! I got the same result: TOSHIBA Model: THGLF2G9J8LBATRH

My XiaoMi Mi5s 128gb version , purchased on 13.10.2016 use the KLUDG8J1CB-C0B1 UFS 2.0 memory. I think all 128gb variants use this memory according to this:
http://deviceinfohw.ru/devices/variants.php?model=MI 5s&set_brand=Xiaomi&set_vendor=Xiaomi.

I have the 128 GB version and used A1 SD Benchmark, result of internal memory is:
480 MB/s read and 127 MB/s write
Using the latest official Global ROM 9.2.1.0.

If your device doesn't have enough free space, the io performance will drop off a lot.

Well, it kinda seems like a false alarm. I've conducted more benchmarks and found out that results are heavily dependent on read-ahead value that you can set in Kernel Adiutor at i\o scheduler tab. If it is set to a minimum default value of 128 then you get results that are natural to eMMC 5.1, but as soon as I increased value to 512 and then 1024 I've got 358 and 160 r/w (for 1024) speeds. Values were used in this order 128->512->128->1024. I forgot to take screenshot of 512 and can't compare it to 1024, but it was close to it and really far away from 128. It might be a lucky coincidence, but this parameter is the only thing that was changed between measurements.

Increasing the read-ahead value will increase your RAM usage and keep the flash, in cases of random reads, longer busy and thus can cause lower performance.

I also have Toshiba UFS memory. Read and write are good.

Well, I'm having like 288 MB/s on read, and only 31 MB/s on write, with ~7 GB of free space.

Once you get below 10-15% of free space, the write rate will drastically decrease on every flash based storage type.

Samsung Note 3 Not Reading exFAT mSD Card Correctly?

Only use my Note 3 to play audio and video files.
Recently noticed some video files missing on a 64GB exFAT mSD card.
1st thought they had been deleted by Note 3.
Just did a chkdsk scan and everything OK. Have a screen capture of this but do not know how to attach.
Additional Info: My Note 3 has stock Android 4.4.2 (KitCat) and never rooted.
Am Open to all suggestions how to correct this problem.

Hey I might can offer some assistance. BUT IM A FRESH NEWBIE TO THIS. I MEAN I JUST STARTED REALLY MESSING WITH MY PHONE 2 DAYS AGO. First what type of note 3 do you have? (ie. Sprint=SM-N900P) do you have service on your phone? Do you have any experience with custom ROMs?

SurageBook said:
? (ie. Sprint=SM-N900P) do you have service on your phone?
I hope not as this is not the Sprint model forum .
OP i would copy data off then full format sd card as a starter .
Damaged files look in the Lost Files folders .

SurageBook "what type of note 3 do you have?" Verizon "have service on your phone?" No "Do you have any experience with custom ROMs?" No
JJEgan "...i would copy data off then full format sd card as a starter." Agree did copy the wanted data.
As previously mentioned have used Windows longer than Android so used chkdsk to examine & fix the mSD Card. Everything was OK and all the missing files were shown and Not damaged,
Since posting I backed up all the wanted data and then put the mSD card back in my Note 3. All the missing files were there and undamaged. Can anyone explain this?
From experience most Windows users reload the OS every few years.
Am wondering if I should Factory reset my Android 4.4.2 OS?
Any recommendations?

Man if you just use that phone for a media device just create a backup of your phone, SD card, and copy it to your PC then install custom ROMs until you find one you like and root that bad boy. My note 3 is my primary phone with service and I have about 10 custom ROMs on my SD card that I switch every couple of days. Earlier today I was on Havco OS 2.8 android 9 now I'm on some rom that when it turns on theres a pink unicorn and its on android 7. Its easier than you think. Things you need are 1. TWRP(for your phone model) 2. Odin(on PC to flash things to your phone*optional) 3. Custom ROM 4. magisk(to root your phone) 5. Gapps (for the android version that's on the custom rom*optional) 6. Enjoy

SurageBook Thanks for the tips!
Do you know if any good tutorials concerning how to root the Verizon version of Note 3?

I don't know about Verizon I'm on sprint but if you go to the Verizon section you'll find a guide for your firmware. https://forum.xda-developers.com/verizon-galaxy-note-3/general

Please guys post in the forum for your phones .
Otherwise i see a reply on here not your models leading to a bricked phone .
