You will need the firmware file to flash with Odin. Use this link to grab the firmware file: https://www.wuala.com/Samsung Galax...riginal Firmwares/Asia/July/?key=AfzUZSU4SpKU
NOTE: This link is provided by "darkstriker" the author of this brilliant post: http://forum.xda-developers.com/showthread.php?t=723596
You can also use that as a reference in case you get stuck somewhere.
Coming back to the point, download Odin v1.3 and the PIT file (512 specifically) from this link: https://www.wuala.com/Samsung Galax...din/Odin & Bootloader(.PIT)/?key=AfzUZSU4SpKU
Follow these simple steps: (DO NOT CONNECT YOUR PHONE JUST YET. IF IT IS ALREADY CONNECTED, REMOVE THE USB CABLE FIRST)
1. Make sure Kies is not running. Ensure it is also not running in the notification area.
2. Start Odin v1.3 and make sure these options are TICKED / CHECKED
a. Re-Partition
b. Auto Reboot
c. F. Reset Time
3. Click on the PIT button and select the PIT file downloaded earlier (512 specifically)
4. Click the PDA button and select the file "ADD_ODD"
NOTE: This firmware archive does not contain any other files needed by Odin.
5. Switch off your phone and start into "DOWNLOAD MODE" using the key combination: VOLUME DOWN + HOME + POWER BUTTON.
6. Now connect the phone to the computer and wait for Odin to pick up a COM port and show "available" status.
7. Click on the "Start" button and wait for the process to complete and the phone to subsequently reboot. DO NOT INTERRUPT THIS PROCESS BY ANY MEANS.
If all done well, you will be back to JG4 in no time.....
Cheers.....

Hey there,
Any luck getting it running properly??
Cheers....

The easiest way would be to update via kies, I tried to get the update notification in the Kies, not updated though, follow these steps to get the update notification in kies.
Connect the phone to kies, and then run regedit.exe , change the regedit keys
[HKEY_CURRENT_USER\Software\Samsung\Kies\DeviceDB\X]
"SoftwareRevision"="I9000DDJF3/I9000ODDJF3/I9000DDJF3/I9000DDJF3"
"ProductCode"="GT-I9000HKAINU"
"HIDSWVER"="I9000DDJF3/I9000ODDJF3/I9000DDJF3/I9000DDJF3"
"DEVCONINFO"=""
X = Device Number
and run the upgrade frimware in kies and you will see JG4 to be available to be updated through kies!!

What were the modifications in the registry. I know modifying the productcode can make a difference with respect to the available firmwares but does changing the SoftwareRevision and HIDSWVER enables us to downgrade the firmware?
On a side not I wanted to revert from JPC to JM1 (through kies with XUE productcode hack). So I first flashed JF3 trhough odin. Now it seems that there is some swisscom stuff left. For instance the start page of my internet browser is now in a german language swisscom site. Any1 can give me directions how to get back to my original stock configuration? Which is dutch OS language and dutch swype JM1.

That i suspect is because the upgrade was done through Kies. Odin on the other hand gives you the option to re-partition. At least that is what I think is causing this. Have you tried the "Factory data reset" option under Settings - Privacy? Or perhaps getting into recovery mode and then doing a factory reset? That might do the trick for you.
Cheers....

Thanks a lot, it worked quite smoothly

The market works properly for you? You can download apps?

I have this same problem.
Was uprading firmware to JG4 via kies then boom Kies went error - send report to MS crap.
Now when I try to odin flash i get
error cache/sec_csc.zip
tried to go back to JF4 tried lots of JG4 firmwares but i still get the same error on reboot.

Yes the market works properly for me, i can download stuff

Hi,
I didn't want to open a new topic so I'll just reply here.
I'm about to flash a custom ROM on my GalaxyS, but I'd like to have an option to revert to original ROM if needed.
I understand that I need that original ROM in order to revert/reflash it, but I'm having trouble finding it.
This is my current, original ROM:

Hello I have a small question I have 4.4.2 version and sim unlocked so i can use any GSM and CDMA My question is: If I got the official version 5.0.1 Is SIM will be closed I will not use GSM in my city Thank you

If you upgrade to 5.0.1 you will lose the unlock at first ask you have to do is install the modem I left in the link and your unlock will return you don't have to input anything else since you already have domestic unlock

my SIM is global unlock
i mean i dont need domestic unlock
i need international unlock work after upgrade to 5.0.1

Not that much different from mine

awesome
First, thank you so much. I followed these directions carefully and successfully unlocked my sprint galaxy s4 sph-l720 (5.0.1) for use with a T-Mobile SIM card.
I had initially installed the StageFright vulnerability patch but after following these directions and flashing everything it keeps bugging me to install the patch again. Will I be able to install this without reversing the unlock?
Also, the phone seems to be unable to send or receive mms (pictures). Is there a solution for this?

I have not tried to install the patch myself
Those are untested waters so I would not be able to tell you if it would mess up the unlock
That would have to be tested firsthand you can always just redo the process if it does not work I have heard

Any ideas about being unable to send or receive MMS? Do I need to flash T-Mobile version of the OS?

So it seems to work when WiFi is off. Sending works perfect but when I receive it comes in as a group with me and the person sending the picture... odd but at least it works. I only have one APN that I copied from my other Galaxy device that I actually bought through T-Mobile.
I should also mention that I performed a step that wasn't listed. I went into my network options and set my preferred network to GSM.
Here are the values for the APN I added:
Name
T-Mobile US LTE
APN
fast*t-mobile*com (replace asterisk with period)
Proxy

I really like having this phone unlocked with 5.0.1 Lillipop but I only get 3G/H+. Is there any way to get 4G LTE? Does it matter? Are the speeds comparable?

As far as I know LTE is not compatible with our model on GSM I've looked for quite a while and came up with nothing

Thanx man
Every things work perficts

Welcome, don't thank me thank s4 devs on XDA the best community ever ......but please feel free to hit the thanks button for me xD

Anyone try this while still on muniz_ri's OD2 100% Stock Pre-Rooted Firmware (flashed via Odin) and still on mf9 bootloader? I'm currently on a custom OD2 stock rooted rom, OD2 modem, and mf9 bootloader, and would like to get on the official OD2 stock rooted rom with domestic unlocked while retaining mf9 bootloader. I haven't read anywhere that it wouldn't work (probably because nobody is still on mf9) but I'm willing to give this a shot tonight if anyone has thoughts on this?

Shouldn't be a problem, just start at step 2.

It's not physically possible. The SPH-L720 only supports B25 for LTE which is only used by sprint it appears.

Enter *#06# in the phone dialer to obtain the IMEI number for the device. You can then enter *#272*Device IMEI#. It shows list of csc s available to you. select INS (THIS WILL RESET YOUR PHONE).

In my device also its not there in system folder. Don't worry its normal. Just dial *#272* your phn imei no #, double check imei. No need to type the last digit ather " / " . Definitely it goes to config menu there you can change the csc. You can copy the imei with s pen from settings menu. Try this.

ATT Note9 Stuck on N960USQU1CSAA

I'm somehow stuck on N960USQU1CSAA, and each time I check for an update, I'm told that my "software is up to date"...
I have an ATT Sim card, and active ATT Service, but somehow my software updates broke...
How can I get N960USQU1CSC1 or N960USQS1CSD1?
Although, I'd prefer to do update.zip, and not ODIN... Any hope for this?
Thanks in Advance...

Why not ODIN man? It may solve your problem.
Sent from my SM-N960F using Tapatalk

Okay, I could odin... Just desperate to get this thing solved... (although confused how I got hung up on an old version)
Where can I get the ATT version of this firmware?
I see a Verizon CSD1 -- is that identical to the ATT CSD1? Should I get OTAs if I install the Verizon version?

Here ya go.

Can I straight ODIN this, or do I have to do anything special?

I always factory reset 1st for best results. Many dont like to lose data but me..clean install is best.
Sent from my Still Rooted NOTE 8

I'm downloading this file now (thanks for the link) - am I correct in assuming that this particular file is specific for AT&T-carrier-branded Note9's? I've been pulling my hair out (what little I have left), since I got this phone, it's NEVER received an OTA update - EVER. After much trial from AT&T tech's, their last-ditch solution was factory reset & wait for system to update. So, I'm gonna do something I haven't done since my Note 2, & ODIN this FW.

I have the same exact problem, I downloaded this last night. Does it need to be odin or can I flash through recovery?

Hi All! I believe this was the Verizon version, but I did it anyway.
Had to use ODIN...
GREAT NEWS:
1.I DID NOT LOSE DATA using ODIN (NON ATT VERSIONS DO NOT WIPE DEVICE~!)
2. It booted up with the ATT Logo.
3. I Immediately got a notification of the April update upon reboot, and it downloaded the ATT update, and installed it NO PROBLEM!.

do bl,ap,cp,home_csc.md5
userdata is just more carrier bloat. but might have things u want. but the one that might cause data loss is csc.md5. but home_csc.md5 should keep it.
but its always good to stars fresh sometimes.... so id actually say fill in all slots and USE csc.md5 to wipe clean.

I have a Galaxy Note 9 that was originally an AT&T Phone in USA. I purchased it unlocked in Canada and I use it on Fido Network. The Baseband version is N960USQU1CSAA. It is running One UI 1.0 and Android 9. Is there any way to root this phone? Do I have to use same baseband version?

Wired Issues (973U1) after downgrade from Android 10 to 9

I was trying to dowgrade my 973U1 from official Android 10 to a previous 9 version. I chose XAA CSC which I wasn't sure if it is correct and the latest 9 firmware (G973U1UES2BSKA_G973U1OYM2BSKA_XAA).
I used HOME_CSC to keep my data. Odin reported success when it was done, but the phone failed to start saying:" can't load android system. you data might be corrupted". I had to do a factory swipe and it worked.
This is where things went wrong. First the adaptive brightness was completely gone. Instead there was an "outdoor mode" toggle, which I learned was a deprecated feature in S6?? There's no mentioning it anywhere after S7. How was this even possible?? The adaptive brightness toggle in the settings is actually for outdoor mode since it just simply put the screen brightness to its maximum.

Later I found that most sensors failed to work, gyrometer,accelerometer and heart rate sensor.
Is any of this due to I flashed the (possibly different ) CSC firmware ? I am about to do another flash again, but could a bad flash bring damage to the hardware?

no. its probably just a bad flash. re-download the firmware from sammobile.com/firmwares and try it again. Use the regular CSC since youve recently used it and shouldnt disrupt too much.
factory reset from within the phones OS first, then factory reset it via stock recovery, then flash the firmware with the CSC and see whats what

Wait if U1 firmware will allow a downgrade, will U firmware allow it too?

It turned out the home-CSC ruined it. Simply use csc, always worked and no additional reset required.
Though it doesn't matter anymore, why would HomeCSC fail every time. Doe something changed in the firmware recently so no data retention anymore?

Now I can downgrade it to any 9 version using odin.

you can flash anything within the same bootloader revision.

im not making absolute sense out of your question, but the reason a HOME_CSC flash wouldnt work is because of the base OS change. Parts of 9 arent compatible with 10 and reverting is way different than upgrading.
