can any one tell me what should i do
Remove battery press volume - or + I can't remember try two options, then plug in usb.
You should see blue screen with DOWNLOAD or EMERGENCY MODE text.
i tried all keys combination nothing work
my mobile internet went dead after flashing quarx rom (I did it wrong btw...), but everything else worked fine.
I couldn't get mobile internet back on track no matter what (it was disabled in quick settings when I flashed quarx), I even tried factory reset and flashing the baltic rom. during the flashing, the kdz updater gave me an error close to the end, and my phone became stuck at the android screen.
even though I have CWR installed, so I could flash it again, I sent it to LG claiming I was updating through their website and since my phone doesn't start. I didn't tell them anything about the mobile internet not working. Hopefully they'll clean the phone completely and that will fix it.
I'll be picking up my phone after work today, I'll let you know how it went.
Same thing Happened to me n almost **** my pants for killing my brand new phone..
follow these steps
1. volume +or-(i dont remember) +camera n power on. it should turn on n say downloading mode.
2. update( you can use kdz updater, it probably wont crash this time but even if gets stuck just w8 for it)
3. after updating, remove the usb cable n turn on the phone, hopefully it would work
4. ENJOY ( N THINK TWICE BEFORE EFFING WITH THE PHONE, )
i am not sure about the keys for emergency/downloading mode(i think it was vol-) GOOGLE IT IF KEYS DONT WORK.
Put to microwave on 2 sec without battery and send do service
my service provider fixed my phone in 3 days without any issues, they flashed the t-mobile branded 2.1 on it. went home and now I have the open europe with fastboot and cwr.
so if all else fails, just send it to LG or your provider.
cheers!
I'm having the following problems with my TAB and would like to know it's fixable. I treid almost everything to fix it without success. I'm hoping someone can help me. Anyone have these problems before?
1. Doesn't charge normally. It would charge but charge really slow like it's connected via us. It shows an x next to the lightening icon when I charge it using the original charger and cable.
2. I cannot go into recovery mode. I get the black screen with the white line. There's also no boot animation when it boots up.
3. The camera doesn't work. I get a fail message when I open it.
4. My computer doesn't detect it in download mode, kies or mass storage. My computer detect my samsung galaxy s i9000 without any problems so I know it's not the computer. I cannot change the firmware because my computer doesnt detect it.
5. I dont have the receipt to do a warranty repair. What are my other option?
AT&T SGH-i987
Firmware 2.2
Baseband P1000XXJHA
Kernel 2.6.32.9 [email protected] #19
Build XXJMA
Any help is much appreciated! Thanks!
Did you register your Tab with Samsung?
If so, they have a record of your purchase and will be able to provide support.
If not, then try this which I got from their online chat: Hope it helps.
"Kyle: To recover the device via the hardware keys, do the following:
Kyle: 1. Power off the handset.
Kyle: 2. Hold the Vol Down Key + Vol Up Key + Power Key for 15 seconds then release.
Kyle: 3.When the recovery screen comes up, use the volume up key and volume down key to navigate through the selections and the power key to select item.
Kyle: 4. Select Delete all user data to recover the device. To confirm, scroll down and select Yes – delete all user data. The phone reboots and again displays the recovery screen.
Kyle: 5. Select Reboot system to restart the handset again. "
Thanks but I cannot get to that recovery screen like I said above. All I get is a black screen with a white line when I try to go into recovery mode. I also purchase this used with no receipt.
U just need to flash a working rom. Try roto jm... in the dev forum
Your tab was modified. I wont blame Samsung if they wont fix it for u

How do i flash to a different rom if a computer wont detect it?
Do you have the latest kies installed? Is USB Debug on? If it still doesn't detect, have you tried android-sdk or heimdall. Each comes with usb driver. I find it hard to believe your PC doesn't detect the tab. I never heard such thing before unless you're the real first victim then...yeah, try to call Samsung and pay a fee.
Yes, I tried to use android-sdk and heimdall but they don't detect my TAB for me to do anything. I also installed the newest KIES software. I also don't understand why it doesn't detect it in download mode. This is the first time I encounter this problem. I flashed my Galaxy S I9000 phones many times without a problem. Is the combination of the firmware and kernal I have that is causing my computer not to detect the TAB?
Is there a way to root my TAB via an APK? I tried Z4Root but it's not working. It tries to acquirer shell and closes after a few vibrate. yes, debugging mode is on.

You've followed Heimdall's README and installed the included driver? Make sure you follow the instructions exactly.
If you have done that and your device still isn't recognised consider trying a another cable, USB port or entirely different PC.

Thanks for your advice but I already tried above. I didn't have any problems/trouble connecting my Verizon Tab and Galaxy S phone to the computers to change the roms. There is most likely something wrong with the Tab. I gave up and contacted Samsung yesterday. I sent the Tab to them yesterday and hopefully they won't charge me to fix it.
The main Samsung Approved Service Center here in Kenya has just given up on my SGS 1900 UK Model Nov 2010, originally 2.1 firmware upgrade via KIES to Froyo 2.21 in March 2011. They have handed it back unfixed after a week. Cant find a problem like this on any forum/google. Can find one that is fixable with the resistor jig, but Samsung dealer says his jigs don't help:
1) Press power, on comes B&W Samsung GT I900 screen, then the mosaic graphic that resolves to the glowing big "S". Then it buzzes feebly. Eventually it goes black but keeps buzzing now and then. Power off works.
If you poke around trying to get it into 3 touch reset, the Menu and Back keys light up and stay lit.
2) 3 Touch reset will not work. Dunno if it ever did as never tried before.
3) Plug into USB charger, it charges fine and shows the charger icon.
4) Plug into KIES and after a lot of attempts, KIES identifies it + firmware and connects. I can see and save my contacts and it displays CONTACTS, INTERNAL SD and CALENDAR folders in KIES. No more
5) ODIN ( which I dunno how 2 use but have) sees the SGS's COM when I plug it to my comp.
6) The dealer claims to have tried to resart/reflash with Samsung jigs. He has handed it back with a "cant fix".
What the heck is going on here? Looks like I have lost a few hundred bucks and have to throw it away.
When did this start? Phone was working perfectly. Suddenly a solid red icon with large white star labelled "Web Page" appeared on home page but no such App was found in SETTINGS>ETC. In any case, "Web Page" just led me to a totally innocuous page I use all the time as a homepage on INTERNET app. A few starts and shutdowns after that ( the battery was getting low so swx'd on and off like 3 times over an hour), it just went into (1) above.
Phone is STOCK, no mods, no reflashes,no rooting etc
Thanks

if odin can 'see' you handset, have you tried flashing the ROM again? find a stock froyo rom from one of the threads here in the general section (click here) or download from samfirmware.com .
Once you have the rom files, kill all the KIES tasks using the task-manager in windows. Get your phone into download mode by pressing volume down+menu button+power button until you get the yellow screen showing the android working. then open odin 1.7 and connect your handset. once odin connects, click on the buttons for PDA,PHONE and CSC in odin and browse to the appropraite file which you've download in the rom. also click on the PIT button, browse to the odin folder and select the 512.pit file. Once this is done, check the main odin window to make sure the check-box next to 're-partition' is checked. click start and it should flash the new firmware for you.
Disclaimer: I do not take responsibility for any harm that may come to your phone during the flashing process. The instuctions above are accurate but are to be performed at your own risk.
flash Darky Rom 10.1 with JVO Modem . Best GPS i´ve ever had, and my GPS was really bad.

@frostygenius
I don´t think that your instrunctions ARE accuarate. You don´t even mention that he has to be in Download mode if he wants to use Odin. Also you advise to connect phone right after opening Odin and than insert the files, but some versions of Odin are known that they malfunctioning if you do this in this order, You should first insert files and set odin and after that plug in your phone.
And if he claims that he is on stock since bought the phone, so maybe he never used it before.
@peterg123
I´m not exactly following what happens to your phone. If I understand correctly the Samsung released defective ROM via KIES and after a week turn it down? But you already updated and now your phone is broken? If yes, I think that Samsung service center should repair your phone or if its serious damage than even replace it.
Is the phone able to boot-up and work properly? Is your recovery mode and/or download mode working? If the download mode (use 3-button combo - VolDown+Home+Power) is working then you can try recover on your own, but be careful, dont do anything before you are sure that you know what you are doing. You can go through this post before start [HOWTO] [REF] [FAQ] [Guides] [Tutorials] Flash/Root/ADB/ROM [MUST READ!].
Also go through the forum or samfirmware.com and find your official version of rom (Eclair 2.1) to be sure that you can anytime revert to this one because of warranty.
EDIT: Also can you please post some photos or video showing what happens to your phone?
Ok, I dunno if this is gonna help but I had a very similar issue when I first got my phone, within a week of owning it.
Points 1-3, exactly what happened mine.
Points 4 & 5 I didn't try, (was fairly new to Android)
Left it in to my local Vodafone shop & within 5 days I had it back in perfect working order, the maintenance report stated faulty hardware, the display module had to be replaced. Maybe worth mentioning to the service guy?

Thanks for the heads-up I forgot to mention those points. I've updated my original post.

Thanks, it is not possible to get into download mode, or I would have done all that. As explained, the phone will not go past the giant "S" logo ( 3rd screen after power on). This problem has happened to many people, worldwide.
As explained the three button default firmware does not work.
The Samsung repair agent claims to have used the 301k resistor method to restart the phone and even that failed. I am not sure if this is true but he said so.. not sure because everybody reports success with this.
ODIN, as I said ( 1.8) recognises the COM connection just as does KIES. The problem is, I am not in download mode so can't reflash if I tried.
I have used the phone for 10 weeks since firmware upgrade from 2.1 to 2.2 during which I had no problems except the occasional process stopped errors.
Hope this help, thanks for trying for me
Yes you are correct, I can't get download mode. The phone has never been reflashed or messed with. It came with 2.1 and using KIES in March I reflashed to 2.2 and it worked perfectly for 10 weeks until it semi-bricked.
There is the Black Screen of eath...then there is the pulsasing S screen of limbo! That's what I have.
The only harwdare clue I have is the SGS blew the fuse in my car charger shortly before "expiring"...yet if connected to USB or other charger, it charges the battery and displays the logo.

..But download mode doesn't display the S logo or even the first Galaxy S 1900 logo...it goes straight in.
Try looking up in the Development section - I'm sure there is a jig method in there and it might be worth trying yourself, you've not got mush to lose now.
If you can get into download mode eventually, search for and flash Ezbase, that will get you onto a rooted firmware and it works EVERY single time for me. Good luck.
@R34L2Pac
Hi, thanks. As posted, the stock UK model SGS 1900 with 2.1 Eclair worked perfect from Nov to March 2011, was firmware upodated by KIES in March 2011 to 2.2.1 Froyo and worked like a dream until it went "semi-bricked" with the "Logo of Limbo" screen ( the pulsating giant S) for no reason.
A week before this, I changed SIMs when I changed countries and for some reason lost all added apps. I had to re-install them and even then, sometimes twice as I got many "android process stopped" errors --- even on some of the Sansung installed ones like Layar. That is the only problem I ever had.
The phone has only had apps from Market and never been modded whatsoever. Many thanks
Hi,
You said that you can see a pulsating S logo, sound to me like your phone is bootlooping. But you didnt mention if you can get at least to recovery(VolUp+Home+Power)? If you can get into recovery, you could try just factory reset your phone from recovery and reboot your system.
Also in the development forum you can find some kernels which can be flashed via recovery (like speedmod K13 for Froyo), so you can try to flash this kernel and after reboot into CWM recovery you could try to connect phone to ADB and type the command "adb reboot download".
I read on the forum that the home-made jig method worked for everyone, so looks like the samsung technician was doing something wrong. It is worth trying to made one a see what it does. Also found this thread, where user cuperus claims that even with charger can be simulated the jig by heating-up your device. So you can also try it, just plug your phone to a charger, let it charge for 1hour and than try use 3-button combo to go to download mode.

Sorry I should have mentioned that it will not get into 3 button recovery mode, that has zero effect or rather, just sends it to the "Logo of Limbo" ( pulsating "S") just as does the power button.
Will maybe try a long charge time and see if that helps! Many thanks
Try en carefully learn hw to use odin coz I gt tha same exact model. I hav flashed mine many tyms en am on 2.3.4 XXJVP. if u do gt into download mode odin will sort u. Regards frm K.poly.

how long have you tried holding down the 'volume down+menu+power' keys? a simple quick press of the three buttons does not work. you have to keep holding them all down for a bit (sometimes upto to 15-20 seconds) for it to go into download mode.
Sorry for the fast answer but I'm at work atm... I think he needs to do the 3 combo button fix on his phone first. I know it's on the forum somewhere... Can anyone check it for him? I lost the 3 combo the first time I updated with Keys from 2.1 to 2.2 and I had to fix it using a program that I can't remember to go on download mode and apply that fix.
Then he can use Odin to flash a stock rom as he needs, plus having 3 combo fixed!
Good luck mate!

Possible fix for your problem
Hi peterg,
I was looking through the general forum and found this post, where user beamzuk1 describes method how he fixed his semibricked phone. Symptoms are the same (not booting, glowing soft-keys, vibrating, no recovery and no download mode). So he used 'adb reboot recovery', I would say that proper command is 'adb reboot download', but you can try both. Also go through guide HOWTO use ADB, which I posted here the link in earlier post.
Hope this will help.
PS: Try follow beamzuk1 step-by-step, because if you start phone earlier than you connect it to pc, adb might not recognize the phone. Also be sure that you have correctly installed drivers and android-sdk before you try this.
These phones come with a 2 year warranty. Why don't you contact Samsung directly yourself - telling them that the local repair centre wouldn't fix/replace it for you. If you did nothing besides what you described, then I would have thought you were entitled to have it fixed or replaced by Samsung.

Also think that Samsung should repair it or replace it.
The fact your repair center has done nothing to fix your phone, in several occasions, now entitles you to brand new replacement or your money refunded in full, contract terminated and expenses paid for your losses incurred as a result of their negligence.
Why not hit them up for the SGS 2.
I had the same issue with my first Galaxy S...wifi stopped working at first, I turned it off then on again but nothing changed. So I rebooted to see if it would correct itself. Bootloops and no 3 button combo (download or recovery)
Sent it off to Samsung through the Carphone Warehouse in the UK. I'd contact a Samsung Service Centre directly if I were you.
Hey guys! Greetings from Spain
I've a Tablet Samsung Galaxy Tab A SM-T580 and it displays the following error each time I power on: "An error has ocurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software.".
I can not go to any menu or somewhere else and I've seen it's a common troubleshoot when root or flash custom ROMs, but I've never done anything like that.
I've already tried the following things:
Connect it with Smart Switch, but the software says my model is not supported. As I've seen in some guides with this troubleshooting, I've tried to test with an older SmartSwitch release or try some options with "More" button, like reinstall device drivers or use Emergency recovery software tool, but device was not displayed on the list and any of these options have worked.
Connect it with Samsung Kies, but device is on "Connecting" status everytime and nothing else happens.
Try to reinstall an official ROM with Odin, however, is not possible to put it in Download Mode as when I press Home + Power + Vol Down it reboots displaying again the same error.
Contact with Samsung support, but they just asked me to follow stupid steps for newbies and conclude telling me I should go to an official technical service and pay as is not under warantee anymore.
Any suggestions?
Thanks in advance.

The only thing I can suggest is to unplug it while showing the error screen, and let the battery run down completely. Then plug in a charger while holding the three buttons.

Pilot error.
You're not holding the 3 buttons for long enough. Keep held down until download mode appears.
Hi,
I have this problem with this same tablet. I've spent several days trying every option on xda.
The one solution that seem to work for some people is referenced in this post:
https://forum.xda-developers.com/showpost.php?p=79232815&postcount=40
I've tried to do this as well but odin fails while trying to flash system.img. Hopefully it works for you.
(somewhere in that same thread it said to get the "cellular south" firmware from sammobile and try to flash that as it is supposed to not have the FRP-lock feature which (among other things) blocks flashing from odin.)
After much grief with this tablet I think the best use case for it is to recycle it for parts, to use it as a paper weight or to throw it really hard into the head of the CEO of Samsung.
Samsung S10 + SM-F975F/DS IMEI stating Taiwan (Update: Very contradicting information if the phone is Snapdragon OR Exynos) if it even matters to solve the issue I dont know
Owner of the above since 2019 without issues; USB debugging mode activated in 2019 and never changed since then.
Samsung always updated which I assume the UI 3 Android got updated in January of my vague memory/recollection (honestly never paid attention of what is being updated, only that the phone needs to be on charge while doing ANY update)
Issue: phone in constant bootloop every 4 minutes with top message in red color "ERASE FAIL: READ ONLY" see photo attached
Cause: happened 4 days ago: Watched video stream on chrome browser; phone froze and applied a 10sec. power shut off (never had to do that before, 1st time)
Investigation:
I tried (found out by doing so) to interrupt the bootloop with pressing Power button and same time Volume Down Button in order to restart it and follow the following commands found on the internet as per UI 3 update:
Recovery Mode as followed does nothing:
Hold the Power button of your device till the power menu pops up and select Power Off. = does not apply as in bootloop
Wait for your device to turn off completely. = it does never turn off completely UNLESS I press Power button and same time Volume Down Button und plug into USB C Data cable of which the charging circle with the lightening strike appears without any percentage % of which photo is attached (phone charge can keep up with its bootloop in order to avoid battery drainage as there is no % indication)
Plug-in a USB-C data cable connected to your PC or USB-C earphones in your device. = I start from here whenever the phone restarts every 4 minutes or whenever I do it manually by pressing the buttons as I described in point 2.
Now, check if your device has a Bixby Button (Such as Galaxy S10/Note10):
Without Bixby Button: Press Volume Up + Power Button for a few seconds.
With Bixby Button: Press Volume Up + Bixby Button + Power Button for a few seconds
After the above steps, you will boot into Recovery mode.
Download Mode as followed does nothing: IT DOES WORK NOW you need to be very fast before the phone starts (recovery mode does not work)
Make sure you have a USB cable connected to the computer
Then press and hold the Volume Down and Bixby buttons at the same time
Continue holding these two buttons down while you insert the USB cable that is connected to the PC
Recovery Mode before update instructions as followed does nothing:
Step 1: Start by turning off your Galaxy S10.
Step 2: After it’s powered down, press and hold Volume Up button and Bixby button (this is the button underneath the volume buttons in case you didn’t know).
Step 3: Without letting go of the Volume Up and Bixby buttons, press and hold the Power button.
Step 4: As soon as your device turns on, let go of the Power button.
Step 5: After you see a blue screen, let go of the remaining two buttons. Now you are in Recovery mode.
Download Mode before update instructions as followed does nothing:
Step 1: Turn off your Galaxy S10.
Step 2: When it’s turned off, press and hold the Volume Down button and Bixby button.
Step 3: Without letting go of the two buttons, press and hold the Power button.
Step 4: You will get into Download Mode.
Have tried all the above methods several times the past 4 days.
Have drained the battery in terms of keeping the phone in bootloop resulting in no power.
Unhooked the battery by means of removing the rear panel and unhooking the battery cable for more then 15minutes and repeat the 4 different methods
Unhooked the mainboard from various connections and put together and repeat the 4 different methods
No indications in Windows 10 Device manager
Questions, doubts and thoughts:
Is it possible in this state to access with ADB of a professional in order to perhaps clear the cache, resolve the issue without having access to recovery mode?
Should I simply try to purchase a new battery even though I never had any battery issues?
I am aware that a motherboard change will resolve it to the cheapest way possible but as I like to save the data such as different accounts this is not an option besides the phone is physically in good condition (never went under water or dropped). maybe to unsolder the flash memory onto a new mainboard as recovery mode might be part of the processor where the RAM is saved.
Any way to drain the entire phone further which may resolve the issue without loosing data. Similar in removing a CMOS battery on a PC mainboard and using a jumper.
Willing to pay and currently living in Europe.
UPDATE: Odin firmware performed by skilled professional member of xda forum, but still not working. EMMC issue which needs to be addressed with ISP in order to fix the issue. unfortunately I was told by local professionals that they do not have the tools for it. Therefor I wonder if someone knows someone who knows someone who can be of help. Location is Spain but Europe would also work.
UPDATE2: Got the phone back from technician who has experience with ISP but still same Error remains as to his conclusion that this is not an Exynos phone of which he has not the hardware tool to fix it and probably no one in Europe will have it.
Thank you very much in advance
Sorry... my english not so good...
so the point is whether you can enter recovery or download mode or not ?

Thank you for following up.
these ones were tried out:
Samfw.com_SM-G975F_DBT_G975FXXS9DTI8_fac
Samfw.com_SM-G975F_DBT_G975FXXU9FUCD_fac
Samfw.com_SM-G975F_XSG_G975FXXU9FUBD_fac
I am not sure but that person who helped me remotely may explain better
According to technician its Qualcomm Snapdragon which can only be fixed with the right tools. Not in europe.
I been getting different information and do require some expertise if someone can please help me
any further advice, input or suggestion?
I also Own Samsung S10+.
its showing the same thing.
tried Flashing Via Odin it failed.
Tried to enter Recovery Mode but also failed to enter recovery mode.
OMG. I thought I was the only one in the world. I sent it yesterday to a data recovery technician to see what they will do since according to some insider in order to recover the data they would have to access the phone and fix the boot of which the problem get solved itself since they can not remove the memory chip itself as it would get ruined. They will diagnose the problem first before they do anything. Obviously a mainboard change would be the easiest but thats not an option.
Was your phone also updated to UI Android 3.0?
How did it happen if I may ask?
I wont give up since my phone is physically totally fine.
Update from a data recovery company its communication:
What we tried to do in order to recover your device's data was to load through the phone's bootloader (in Download Mode) a software agent that allows us (in some cases) to transfer the data stored in the data partition. This software agent has been developed by us together with some of our partners and as we are sure you will understand we cannot give you more details about what this particular software does or how it does it, since this information is covered by professional and business secrecy.
In this case the phone's firmware was damaged to a degree that made it impossible for the information to be accessed with this software.
At this moment, we doubt the data could be recovered by any software available now in the market. That's our opinion, but you can of course send it to other companies to see if they can recover it.
Since I am not the only one anymore with the same issue I recommend for people to come forward in order to get help
So far there is a tool needed to reprogram EMMC but I dont know which tool neither do I know where to find that person with this knowledge

Your device is powered by Snapdragon or Exynos?

I honestly dont know anymore since numerous people said contradicting things.
I am under the impression it is Exynos as of the research of the model SM-G975F/DS
Need to know exactly if it's Snap or not. If it is, then there're 2 options you can try.
1. Ask some one have the same device model as you, do a ROM dump ( you can google for more detail ). Once you got that, I can share with you the tool needed for restore your device from that dump.
2. Try find your device's Factory Images ( similar to Fastboot ROM, but a little different ), and an authenticated prog of your SoC ( this I can share too if you choose this option ) then boot your device into EDL mode by using fastboot2EDL script ( on Git, you can google too ) then use QFIL ( one tool in QPST Tools by Qualcomm ) and force flash the images into the device.
So far as my experience and understanding, there're only these 2 solutions to fix your device ( if it's Snap powered ).
According to the seller: "The phone is Taiwanese version and CPU should be Exynos 9820"
Maybe someone can help me please.. still
If its Exynos powered, then I have no solution for it. Sorry bro!!!

Hi mate, My phone is Snapdragon powered..
My problem is almost similar.. But not exactly.. After almost 2 months I am not able to find a solution.. But after this period of researching and googling about things related to my problem.. I feel now, either any one of the following is the cause of problem:
1. Emmc is stuck or locked in read-only mode `(Can move files from pc , delete already present files anywhere in any directory, but all changes vanish after reboot... all file and directory structure remain intact- moved files from pc gets deleted.. and deleted files which were already present come back after reboot )
2. Corrupted /data and /cache partition, as e2fsck in twrp terminal results shows "filesystem still has errors" and "e2fsck: unable to set superblock flags on /dev/block/mmcblk0p** ) in both these file system (I think they are preventing flashing procedures- Odin stock firmware flashes and twrp custom ROM flashes both are successful, but after reboot no changes can be seen... - Even Recovery.img and boot.img flashes don't seem to work even both are shown successfully flashed in twrp) After reboot current version twrp boots again instead of newly flashed different version recovery.img ... same with boot.img even after running magisk uninstaller zip files.. running uninstall.zip 2nd or 3rd time also shows magisk patched image detected in log which should be removed in 1st iteration itself..
3. Might be magisk is preventing these changes to be made.. or It might be the /System_root creation as mountpoint for system partition which used to be previously /system normally. This might be the superblock creation which not used to be there
My Samsung's twrp and Download Mode seems to be working but no changes made by them even after successful operations by both.
Can you suggest anything? You can look my thread as to get even more detailed overview of what's happening and whatever I'have tried here - https://forum.xda-developers.com/t/...t-not-changing-anything-after-reboot.4462639/
You can see my attachments in my above thread to see my directory structure of system_root and my download mode pictures and odin system ROM flash pictures.
