[Completed] Galaxy Tab4 Firmware problem - XDA Assist

Hi All I wonder if some kind soul can help with a problem I have with a Samsung Galaxy Tab 4 10.1. (SM-T530) when switched on it displayed the Samsung banner after this the pretty Samsung logo appears with like coloured spots flying around it, I have not seen this Samsung log before and I wonder if this is some indication of the software it is trying to run.
After a short while a screen appears with a message in "SPANISH" which translated says. "data partition is damaged. need to reset your device to factory defaults. so all data will be cleared" at this time the up down volume seems to work as should, and displays the slider graphic. Other things seem to work OK with this screen when buttons are pressed they make the squishy noise.
I have tied to get into the boot recovery screen but get a graphic of the Android for a second then the Android on its back with flap open and the triangle then the thing reboots.
I can enter Odin mode but when I try to recover the device with a load everything seems OK with the initialisation until the start of the flash then I see "MMC: mmc_write fail" on the Tab.
I have tried different PCs, different MS platforms, different USB leads and ports. Kies sees the tab seems happy downloads latest software then same thing again "MMC: mmc_write fail" I have no idea what software was on the Tab, I also think that there is more info available on the USB port which I cannot see.
When I plug the Tab into the USB port of my Linux pc it is seen in "Places" as Samsung tab but when you double click on it an error message comes up on the PC "unable to mount file" could some one with some engine room knowledge pleas help.

Try to flash stock firmware with 4 files & with pit too , if no luck then center services its better for you ..
Good luck ,,

Hi Thereassaad, Thank you very much for you reply to my post. I have tried your suggestion and this has failed to fix my problem, I also tried to run the .pit file in Odin but still the same results, I did suspect that my problem could be a hardware issue as I have read in other posts that there may be a problem with memory damage under some types of memory write operation although I am not sure that this applied to SM-T530.
I obtained this Tab from ebay as a project in self learning and I have had plenty of fun tinkering with it already. I have found that there is not much in-depth information on the web about the architectural structure of the firmware on Samsung devices but I shall continue to tinker. The Tab I have has no indication of being tampered with ether by attempts to root it or tampering with the innards. I only want to return it to stock Samsung firmware eventually. I do feel that the firmware is unable to write enable the flash and I am still not sure whether this is a firmware or hardware issue.
I am going to try a comms program to see what information is available at the usb connector as there is quite a lot going on which we do not see with Odin and Kies such as serial number confirmation, firmware versions, etc. I may try to use my comms program as a sniffer when Odin or Kies talks to the Tab on initialisation.
If you or anyone else has any good ideas, I would love to hear
Thanks again for your help.

Have you tried accesing the recovery or download mode, by pressing the top/bottom volume? If so, you should be able to just flash a new fimware onto it.

I too am experiencing this with my N8000.
What you should do is when you start or power on the device, Just leave it sit frozen with the writing you too.
Eventually, the device does boot, its like has a corrupt partition, or some type of corrupt memory or drive, or at least thats what I suspect.
Still experimenting and equally frustrated by this.
I also bought a used fully functional N8020 4G version to see if I could replicate or assist trouble shooting.
My efforts show that both S Pens works on the N8020 fine, and both S Pens do not work on the N8000 which has the boot issue too.
Tell me, does your S Pen work fine if and when you get your device booted?
Its really weird but if I dont get it sorted soon, I might just keep the N8020 and ebay off my N8000 which is a shame as both are cool, but I only need one & especially one that works.
Would be keen to hear from other users with similar issues or fixes.
ps:
I have tried a couple of stock roms, and issues (slow boot appears frozen and no S Pen functionality) are the same.
When in recovery, caches cleared and full factory date wipe data and install.
Other symptoms.
After doing the total wipe and reboot, the device still takes it time booting to do the install.
With and without charger inserted, its still the same.
Another point, when you turn off the device, the battery icon appears, it hangs on the battery picture with a little circle on it.
After about 2 minutes, the full battery colour progress icon shows and shows the charge happening.
Hence, suspicions towards potentially corrupt memory or drive, plus maybe cracked circuit board even? I rule nothing out here.
There you have it, appreciate feedback or other recommendations.
after installing a stock rom the tablet starts in bootloop then I discovered that letting the battery becomes exhausted, re-starting recovery screen appeared, I pressed on wipe memory rekindled and tablet restarted without encountering any difficulties.
The s-pen did not work because the csc was unknown, after flashing the right csc the spen has started to work well.
Anyway attentive to the stock rom you have installed I Have flashed a (4 files) from a site very close to samsung and it was fine, another downloaded from another site (1 file) not good.
Excuse for my bad english and I hope to help you

Hi Sirduffy,
Hey, thanks mate.
I only just finished doing some testing and made some progress myself.
It seems that it was one ROM that I seemed to get bogged down on.
Here is what happened for me.
I was using
Australia 2013 February 4.1.2 N8000XXCMB1 N8000XSACMB1
http://www.hotfile.com/dl/197957288/5d7de66/N8000XXCMB1_N8000XSACMB1_XSA.zip.html (GAVE SLOW STARTUP + FREEZING)
I then just installed this, and then did a cache wipe and full wipe reset. Now it boots perfectly every time.
Australia 2013 March 4.1.2 N8000XXCMC4 N8000XSACMB1

Excellent, this is likely exactly the info I am looking for.
Can you tell me, is it possible to update only a CSC file with Odin 3.07 flash??
Or do I need to redo the whole ROM above and also include a individual added CSC file?
If so, where do or can we access these files or choices of files to match my Rom, or country, N8000 model etc etc.
Or where or how did you get your one?

You out there still SirDuffy?
Can you please elaborate a bit more on where to get such csc for the S Pen to work.
My Rom as mentioned boots up fine and shuts down and does everything perfectly except S Pen which does not work.
Or at least when I pull the pen out of the tablet the Shortcut sidebar pops out confirming the pen is in use.
Would really appreciate more info or instruction if you can help.
I read on a few other threads about how to change CSC but I do not know where to get or what I am meant to be changing as yet.
Plus I am wondering why this would even be the issue when the CSC (Consumer Software Customization) denotes to a specific geographical region or carrier. The CSC code contains the info about software packages specific to a particular region, carrier branding and also APN (Access Point Name) settings for data connection. (as written from droid views).
So a little lost in the S Pen department.
Any body else out there got any suggestions to why my S Pen does not work?
I have done some tests as mentioned above previously and any suggestions would be great.

Hi again folks,
Just replying to myself to advise others who may also have similar experiences as this, that I have now fixed my issue with S Pen.
I went back to ICS Stock Samsung 4.0.1 XSA, done a cache clean, then full data/wipe to finish install.
(with the SPen always inserted).
I then updated to JB Stock Samsung 4.1.2 via Kies, which also shows that the Pen is still working.
This is a very weird problem when it happens, how it happens, or why is not exactly known.
But my guess would be a partial corruption at some stage, some where through a process or a combination event that corrupts something obviously.
Anyway, persistence wins the race in the long run.
I have never rooted my device and always installed Stock Sammy Roms which for this model for me there are only 2 (but a 3rd using a different country as I did also use a German JB Rom to also try a CSC change, which also needs to have a cache reset and Data/Wipe type install too. And then when moving back to the Rom of your country of requirements, also do these cache cleans and full Wipes each step of the way which also enables the correct CSC as shown in Recovery Mode.
Eventually its like the device just gives in and surrenders back to S Pen Functionality.
The last thing I am going to say is that my device was or is still under warranty through Kogan.
I told them via email that I had been trying a few ideas from reading this site and they then in some way accused me of flashing with a custom rom which I have not.
---edited---
To this day, my N8000 has had NO Custom Roms on it, and I am totally Sickened by the fact of their reply which still shocks me.
But then, hence my reply.
All the best out there to those with S Pen issues or Bootup Freezing, as XSA through time will help you be persistent and move forward with or without warranty providing you have the patience to succeed.
Cheers~!
I have sent you a private messagge

Guess you'll wait forever.
What a sick advice that was.
Read about flashing with odin in download mode + go to sammobile web page and download a for your device - it's a BASIC knowledge, you must know.
Bootloop does not mean that the internal drive is corrupted; it is the least possible issue which may happen.
Bootloop means that the system files are messed up or kernel is wrong or blah blah blah
Don't think too much about CSC... just flash the full firmware with odin and your device will be working again. Btw, firmwares are described with CSC names: i.e. XEO for Poland, EUR for Greece, etc. Choose one your CSC - or any other you wish (it will work without issues; you will have your language version; some not essential added content may differ only...).
And if after that your device will still refuse to recognize s-pen then it's a good point to admit that it's a hardware issue.
You may want to regulate spen potentiometers hidden under the button, with a knife. But that's the other story.

[Q] I9000 Not working due software mess-up

Hey guys!
First off, i was searching through loads of forums and attempted different solutions. Anything to get it back working. This only made it worse
What happened was as follows:
After having CM 10.1 or some version of it (had the OS at 4.3 i believe), my phone was very slow, so slow in fact that i got so mad at it that i almost bit through it. So one day when i was in a tent at the foot of a mountain all alone (not that long ago) i decided to rollback the phone to its original state from backup i made some months ago before i upgraded the OS. At the same time just before this i backed up the current build just in case. Using ClockWorkMod 3pointsomething.
It went through everything and then asked me: Do you want to root this device? (or something in those lines). I, having no clue, clicked one of the million "no" on the screen.
After this it rebooted with errors saying "Can't detect this drive can't detect that drive". In other words, it couldn't detect niether Internal SD nor External SD. While having the Samsung logo being displayed without booting if i didn't go into "Volume Up, Menu Key and Start your tiny engines!".
I thought i could fix it and looked through tremendous amount of internets in attempt to fix it. Neither Odin nor Heimdall Frontend could detect the device even after installing the drivers and samsung kies and messing about with those two in between.
After a while i ended up with "Phone . . ! in a orange triangle . . PC" aka black screen of death, while the phone can go into download mode. Which in my hand is equally useless as no program can detect it still.
Now i just decided to start a new thread even though there is endless amount of other threads but none seem to cover exactly this as i haven't yet managed to fix it. Plus a response on progress is always pleasant as i personally don't know when i succeed unless phone works fully again.
How bad off am i?
Any input will be greatly appreciated! :victory:
Hoping not to have to spend money on a new one and as far as i've gathered this can be solved - Anybody can give me some tips on where to look or what i could try?

First you are posting in the wrong location as i9000 has its own forum here for Q&A and others too
second click on My Android Solutions (link below) and try methods to fix USB connection problems first after that get into download mode and use a rescue kit from MY Android Collections (link below) or follow this to flash a Gingerbread JVU stock ROM
Check this out! You , YES! you are an " Android ". Not your phone but U.​

[Q] Got Galaxy S6 live demo unit. Model no. SM-G920X. Need help

Anyone else have one? I want to completely remove the demo software and use it as a tablet. Now please note I am looking for an answer that puts the instructions in steps like you're talking to a baby. Assume I have no experience in any of this. I also only want answers from people who have been successful at doing this and own the device.
Also I want to know: are the specs of a demo unit exactly the same as the normal retail version?
Build number if needed is: LRX22G.G920XXXU1AOD7_LLK
Bought in the UK.
So far I've turned the demo stuff off as far as I can. I entered the password 5444 and whatnot to disable it.
Also:
Fast charge doesn't seem to work. Charges quite slowly.
I get this error when I try to install certain apps: unknown error -501.

If it's a live demo unit it's probably crippled in most ways. Wifi, Fast Charging, Cell Radio, things like that are all probably affected by this. Live demo units are primarly there to show a "finished" product. It's there to show of how pretty the exterior of the phone and the screen. Maybe the camera. But it's probably a pre-release version. You're going to have a bad time trying to make it work for your needs. Best of luck.
Thanks but I'm looking for help from people who have the demo unit. I have a galaxy s4 demo unit as well and it's fine, had no problems
OT why are u fun of getting demo units, aren't these supposedly be for demo purposes only?
Why not get the retail and get rid of issues. If u bought it then you should be getting a retail/production phone than demo UNLESS you paid it for less ... Lol

Yes I bought it for 1/3 the price of the normal phone, and I don't need the phone features. I am asking how I can completely remove the demo software. I prefer someone who already owns it and has tried it, to answer.
I've bought the same. mine is clearly removed from display because it's had a bash. So I think it shouldn't be a problem.
I've been trying for the last couple of hours. Can you get yours to be recognised by odin? I couldn't at all.
I turned developer mode on to use adb sideload but it has been no use. the device says everything has the wrong footer and validation denied.
what else do you have besides 5444? That's the first I've heard of that.
Hey Quarzar, the other password needed to turn disable factory reset off is M729Q16K8546, after you've entered 5444 to enter the Samsung Retial software. But even after factory reset I'm stuck with the demo software. I haven't tried Odin, will have a look. I don't want to flash something and risk bricking it.
Quatzar can you try something? Can you try installing 3DMark and run the ice storm unlimited benchmark on your demo unit and tell me what you get?
I would love to but I went looking for what you'd used. found the factory reset code. wiped.
signed in including the fingerprint thing. Samsung installed a software update even though I didn't sign in for samsung. wouldn't let me cancel it. It auto rebooted. Now I can't unlock the damn thing. It knows it should check for thumb prints. won't do it. There is a backup password thing but it won't let me use it.... I'm locked out.
It might be deliberate.
Darn that is annoying, so glad I never tried the fingerprint thing now. It auto installed two updates for me as well without asking me
Easy easy dude
Hi, look its very simple!
You have to ROOT your device, then istall Titanium Backup on it and the open up the Programm and through its options you can UNINSTALL anything you want, even the retail software! Thats it:good:

Ok back awake now.
If anybody gets locked out, just use android device manager in a browser and wipe the device.
If you download this.
https://download.chainfire.eu/733/CF-Root/CF-Auto-Root/CF-Auto-Root-zeroflte-zerofltexx-smg920f.zip
Extract it. There is a copy of Odin in there and the file you need to flash with Odin.
Run Odin. The window will open....
Shutdown the demo unit. Then hold down down+home+power until the logo "demo unit" etc comes on.
It will go into the warning page. Press up to put it in download mode.
Connect your computer to the unit with the USB.
But my guess is of yours is the same as mine Odin won't recognise the unit.
Does Odin show a blue/green bar?
Does text come up in the message window?
If it does find the zip file that came along with Odin inside the original file I linked. Put it in the box that says PDA (or its PA now I think from memory they relabelled it.)
Press start.
I bet it doesn't work and nothing will change.

Please can you show me how to root it in baby steps? The most important thing is, have you done it yourself on a galaxy s6 demo unit? I don't want to follow a procedure for the normal s6 and then end up bricking my device.

Hi Quatzar, yes Odin recognises it I think. It says 'added!!' and the blue bar under ID:COM. When I plugged the S6 in at first it did have to download 'Serial Gadget' update and Samsung something. But I don't want to flash anything until someone else has already tried it and succeeded, in case it ends up going wrong.

Does Odin show a blue/green bar?
Does text come up in the message window?
If it does find the zip file that came along with Odin inside the original file I linked. Put it in the box that says PDA (or its PA now I think from memory they relabelled it.)
Press start.
I bet it doesn't work and nothing will change.

After flashing this file my demo live unit stuck on Samsung logo, any help please

Bypass Factory Reset Protection on Samsung Galaxy Tab S2 without using Sidesync? HELP

Okay so,
I've been up and down the internet for the last few days reading a plethora of articles and how-to's about how I can bypass the Factory Reset Protection on my Samsung tablet. Out of all of those articles, I have struggled to find one that doesn't rely on the use of Samsungs "SideSync" screen mirroring program. I run Windows 10 on both my laptop and desktop computer. For some reason it seems to have trouble starting the Sidesync program... This could have something to do with the FRP lock being activated on the device, because I dont have the Sidesync app on my tablet, and I can't very well install it when I can't get into the tablet to begin with, so my computer's version of sidesync might not register the device as being there..? idk
I do know that my computer recognizes my Tablet as a Samsung Tab S2 and any other file transfers from my hard drive to tablet have been operating normally.. So I have all the correct drivers for my device, and for Sidesync (I re-installed just to be sure) but when I plug my tablet it, I fail to get the "Open With" pop-up that the articles mentioned that my tablet should get, and Sidesync never gets past the initial screen... I press start, and it shows the directions on how to use it, with the word "Starting..." and a time wheel, like its loading up.. but never does. It stays like that until I close it... its not frozen. It just never recogizes that a device has been connected.
Can anyone help me with this dilemma? I need a way to bypass the FRP "Google Account Verification" lock that doesn't rely on Sidesync, or someone that knows what I'm doing wrong to make Sidesync behave like this. I've been able to flash different versions of Android onto the Tablet, and have even downgraded my version a couple times to see if it made a difference.. annnd it didnt.
So I'm stumped... if anyone knows what I can do It'd be greatly appreciated!

Tab A help - bricked with nothing but 'Warning: -CMDLINE Parameter Modified'

I tried to sort out a never used Tab A (2019) that had a locked build (MDM, no access to system). I used Odin to install a ROM image which I believed at the time to be correct. It didn't seem to go right, halted at Param. Eventually i had to close Odin and now the Tab A will only charge and, when i do power+vol up+home all I can get is the red error message and the lightening bolt even though it's not charging. When I connect to my PC it is not detected.
I have searched for previous questions like this and watched Youtube vids but no-one seems to have a solution for my example. Thanks
