So i have seen many guys charging a good amount of money for this, DFS is charging like 50$ per phone. Many guys are struggling to get thr phone working since they are unable to flash Akey/SPC which is needed for some carriers like Reliance, TATA in India atleast.
I'm not going to put usual diag setup stuff right now, or may not able to update it at all.
The below commands should be sent step by step as mentioned through DFS or CDMA workshop or any other tools which you prefer to use. Also you need to first send the 16 digit password for your phone model. I believe for L720 it is "2012112120131219"
----To change SPC to 000000 or any anything

In the second last line i.e. "4B1305000000000000000000303030303030", the last 12 digits are your SPC hex value, if you want to change it to anything else like 123456, you need to edit the last 12 digits and make it look like "4B1305000000000000000000313233343536"
----To change the A-Key to anything, in the below case, akey decimal to be flashed is 11111111133333333785 (the akey hex will be: 9A3298B4E238A719)

In the above cmds, if you take a close look at the last 16 characters in the 2nd last line and the mentioned akey hex, you maybe observe that the akey hex in the cmd is in a reverse manner. You can change generate your akey online or via regular tools like DFS and arrange it in the similar manner to flash. You might need to downgrade your modem in order to get this working, please post here if it works without downgrading the modem.
This has been tested on 2xGalaxy Victory and one Sprint L720, so please test and report if this works for you.

Good write up. I flash phones and make tutorials. Some people on here claim they can do this and do that but, haven't written a clear guide yet on how to do it. Lol But, my guides are free and to the public.
Also this should be in the general section. Development is only for roms, etc.
as for resetting the SPC, you will need to downgrade the modem from MF9 to MDL or MDC... i have tried it with MF9 and didn't work...
thanks for sharing

If you dont mind someone asking, how do you downgrade the modem? I tried to downgrade the complete os from samsung-udpates but nothing has worked for me.... any other suggestions??? thx in advance
to downgrade the modem just download the old modem's tar file and flash it via odin.. it should work without any problems

I actually tried that and still nothing! Maybe i just have a phone that wont take....? I have tried several os downgrades and last resort was the modem downgrade and still the same result: UNABLE TO USE THE 16 DIGIT PASSWORD TO ACCEPT ON WORKSHOP.....
I appreciate your input and help brother thx again.
If you're serious about flashing phones you should invest the proper amount of money, in the proper tools.

Thank you this is the only thing i have seen that has actually had some success, at least i did not get any errors but how do i know if the akey is in if i press read i just get a lot of cps errors. DOes the trial version of dfs not let you do anything in the cave ?
anyway thanks again hopefully this works.
Many parameters on a number of phones are write only, so you won't be able to read them.
flashing rom fear
So I got my phone working on my cdma carrier in Indonesia. But now I am concerned about flashing New roms esp using Odin and factory resetting. Will I lose my settings with a factory reset?
How do I flash roms and still keep my network settings?
Thanks

Using cwm to flash another rom
Sent from my SPH-L720 using XDA Premium 4 mobile app
I have a Sprint SPH-L720. I tired to use the command 4B1305000000000000000000303030303030 it accepts it but responds back with a differnt command and the SPC doesn't change.
I did downgrade the baseband to both MDC and MDL with it still not working.
Any ideas how to change the SPC to 000000?
Been awhile but I thought I posted an update. Downgraded to the MDC modem and tired again and it solved my problem.
Thank you for the awesome post.

You need a PC software such as DFS to send these command to your phone. You also have to enable diag mode in your phone before connecting it to the PC's USB.

Hi! I have completely F***cked up my USA SM-T813. First post, so im sorry if i get posting etiquette wrong.
##TL;DR I turned my tablet into an asian one with firmware and idk how to change it back##
So, since about march of this year (2018), I had a galaxy tab s2 (sm-t813) rooted with SuperSu. I have just recently heard about Magisk and really wanted to switch. well, from what i saw on switching, i had to (obviously) uninstall SU and install magisk. while i was reading, i read that i had to do some abd bull***t and other crap. well, i guess i did that wrong, which soft bricked my tablet. I managed to fix the soft brick, but now my tablet has the firmware of an asian one. i have no clue what i need to do to fix this. I have downloaded the correct (fingers crossed) firmware, but odin wont let me put it in. It stops at "connection *something*", which when i looked up probably means i need to install the drivers for this firmware. The problem is, i dont know what nationality this firmware is.
The file i downloaded was T713ZCU2BRA4_T713CHN2BRA4_CHN
the CHN at the end made me assume it was Chinese, but when i installed the chinese drivers, it still didnt work.
if anyone could help me get this fixed and (possibly) help me get magisk installed, that would be amazing.
thanks in advance!
Coltonious
P.S. the firmware change unrooted my phone. so supersu is gone. thats a plus i guess!
##TL;DR I turned my tablet into an asian one with firmware and idk how to change it back##
What now? T713 or T813? The chinese firmware you mention is for 713 and not the other one. USA you say? Well that should be Country code XAR: https://www.sammobile.com/firmwares/galaxy-tab-s2/SM-T713/XAR/ OR https://www.sammobile.com/firmwares/galaxy-tab-s2/SM-T813/XAR/ load the most recent of these fitting to your device. And yes, CHN is China. Odin drivers are not country specific. You get one working and all is fine. If you get these errors you mention then the driver is not working or is the wrong one for another device. I use the same Odin driver for all my devices I have and had from Samsung. Some more detailed error description would be useful though. If you have problems loading with reasonable speed from sammobile: https://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647 try this tool.
I don't know if it matters but you stated you have the sm-T813 and you are trying to install firmware for the sm-T713.

Hi All,
Just got a VZW branded note 8 and I want to flash the US XAA unbranded firmware.
Can anyone point me to a location to get a decent download of the official firmware that will not take 17 hours?
updato, samfrew and sammobile are all predicting between 8 to 16 hours for download?
I'm looking for the XAA version of this one N950U1UEU6DSH3
It is on all the sites but the download crashes or is going to take a very long time.
Thanks

If you're on boot loader 6 it's more than likely not going to work.. I just tried to help someone else do this very thing with the boot loader version of 6 and it didn't work not with the regular Odin and not with the prince comey Odin.. I haven't seen any other way to do it or anyone else do it yet but you can check the page on here that has directions on how to do it but that's only for the lower boot loader versions..
Thanks so what you are saying is that I can't even go from BL6 to BL6 unbranded.
That sucks that it is not possible at all.
I'll reread the guides but since they were older versions, that was the one reason I asked the question about firmware location hoping some one had it on a Google drive or something I wanted to give it a shot.
I'll have to go the route of adb shell to disable stuff then.

You can always check https://androidfilehost.com that's only one I use since the rest of them are too slow and do that on purpose to try to make you want to pay for the higher speed. And no I don't think you can flash it at all at this point because like I said I just tried it with someone else and it would not work.

So i´ve been locked in the KG State Prenormal for about 2 months now, two weeks of it i kept the phone connected without rebooting or removing the SIM...
I´m on my limit right now, just a few sights of the word "Prenormal" away of smashing this pieceof sh*t (1000 euros piece of...) against a wall... the use of an hammer also crossed my mind...
I´m about to give up, and sell this pos to buy a phone that actually would belong to me and not to the brand that sold me... Cause Samsung is NOT that brand, also i might never buy anything from these control freaks psichos again... anyway i digress...
After testing all guides i could find, flashed several ROMs i realized that the mistake i made was to update to binary 4... now i´m stuck...
Anyway, after all this, i stumbled upon this file "COMBINATION_FAC_FA81_N960FXXU4ASJ2_FACFAC_CL13996359_QB26885160_REV00_user_mid_noship.tar" that i actualy can flash, but can´t do much else with it...
It has binary 4 and is a very slimed down version of Oreo 8.1. I can install custom binaries, including TWRP, but can´t boot to it.. the phone just reboots.
I can even flash the magisk_patched AP i got, but then the phone wont boot at all. Can´t overlapped it with my stock rom cause then i got the error that the binaries are mixed up...
Not even with the Oreo ROM cause the binaries wont match...
Once in the OS i can access lots of hardware tools, but can´t install any apk...
So i wonder, What is this crap for? How can i use this?
Anyone here used a Combination file before? For what?
As i guess i have a few more tries before i just smash this phone, any new tips regarding the KG issue are also welcome.
Special thanks to bober10113 for the incredible patience he has proven to have...
Also to Mr. Ketan, that despite his very detailed and awesome guides, i just can´t seem to get rid of this crap... Thank you for all your amazing work that certainly saved a lot of other users... just not me...
And people, DON´T GIVE REMOTE ACCESS TO YOUR PC TO ANYONE CLAIMING THAT HE CAN HELP YOU.... You know who you are! Scammer!
No Hangouts chats! If this sorry excuse for a human had a real solution, he should share it with the community, not pull you over aside...

Combination file is used mainly to remove google account locks or some other kind of locks, also to downgrade fw versions.

Can you explain HOW can make a downgrade of fw?
I updated to version U4, and at this moment can´t flash fw U3, because Samsung...
I tried to to flash U3 fw over this Combination file, but always got the error "...Device 4 Binaries 3..." even without the BL file on Odin.
In fact, even when flashed individually, BL, AP, CP and CSC give that error.
So, how can this file help me?

Hello there, I'm stuck with a situation and I can't fix the phone.
I live in Canada and I bought the phone here (Canadian software version and also unlocked) and gave it to a relative who lives in the USA to use. Recently, she has a firmware update notification from her phone, however, it always gets stuck at 28%, and the download fails. So she plugged the s10 device into her computer and used Smart Switch to download the new firmware. After she finished downloading it, she clicked to install the new firmware on her phone. That's when the problem starts... She got stuck on this screen forever and she even tried to soft reset/restart the phone but it just went back to that screen.
What I think happened was it's a Canadian version phone but the new firmware is the US version and it tried to install and crashed.
Could anyone give me some advice on fixing this problem?

for sure man, i sometimes skip the long winded Odin stuff because ive typed out like 3 paragraphs of Odin instructions and the person i was replying to already knew 75% of what i just typed LOL
aaaaanyways, downloading Odin from a trusted source isnt an issue. Ive downloaded soooo many versions of Odin over the years and from so many different places, i cant imagine an infected Odin. Im sure they exist, but ive never seen one. ive got Odin from here before, and it was fine. Also, yes, youd definitely want to download the canadian version of it. You should be able to flash the U1 version (fully unlocked) so long as you have a snapdragon processor, but youd need whats called "Patched Odin" to do it. The U1 thing is kind of a tangent, but youll find out that there are a TON of rabbit holes you can find yourself in from time to time. The best thing to do is to just flash the FW for the model of phone you own unless you plan on tinkering. sammobile.com/firmwares is where you want to search for the FW and samfirm is an exe youre going to want to use to actually download the FW itself. Samfirm downloads it literally 5x faster.

For the firmware, do I just download the latest one for Canada Version? There are so many links so do I just click on Canada (the one without Provider) and Do i download PDA or CSC or both? My phone is unlocked already btw. Also will i able to flash my phone even though it is currently stuck in the "BLUE SCREEN OF DEATH"?
I even tried to you the samfirm to download the firmware but it keeps saying authorization failed after I filled in the blank and clicked update.

yep. sorry, i forgot to mention that part. Zero worry tho, its just a thing caused by the bootloader that your phone was most recently on being too new for the FW youre trying to flash. Thats whats causing the binary error, the binary currently installed is greater than the one youre trying to install so the phone wont physically allow it. Its not even a software thing, it gets hard coded. Anyways, get the most current one and reflash. It wont fail again with the same reason on the newest firmware, but if it does fail, try a different cable, download the file again. it might have corrupted during the download. If youre not using patched Odin, you literally cant screw it up so badly you cant recover it

thanks you! I used Frija to download the latest Canadian version of the firmware. Next step do I just use the Odin to flash and follow the instruction on sammobile websites? Can I flash the new firmware without deleting data on my phone?

yep, when flashing the 4 parts of the FW, the home_csc will not wipe your userdata, csc will factory reset. let us know if you run into trouble, but you shouldnt have any issues. it sounds like you got this
Thank you so so much! I fixed the phone and it works now. For future firmware updates, I have to do this every time? Is there any option that i can change my firmware permanently to the US version so that I can get auto-update on the phone instead of using ODIN every time?
