How can I change product name on odin mode ?

Hi, I'm using gt-p6201.
Maybe it will be some strange.
Anyway, I flashed 6200 rom for my 6201.
It works great.
But!! It changed my bootscreen(original bootscreen was
galaxy tab plus 7.0 N, now just galaxy tab plus 7.0)
And, prodct name on odin mode changed.(gt-p6201 -> gt-p6200)
Anyone can help me ? I need you help. Please T_T

Um, i believe GT P6200 and P6201 is only differ at design, so i think that's okay and no need to change ?

unless your sending it for repair/etc. Then its recommended to flash a stock Odin anyways, which should restore your model number.

Thank you for reply.
I considered refund this device.
But, bootanimation & product name makes me crazy. T_T

So, I just need it. T_T
I try to flash original firmware(p6201) by odin,

Wipe every single partition, then flash the latest stock from fus downloader.

Thanks.
How can I wipe every single partition ?
It means just factory reset/wipe cache ?
If it is not, please tell me how I can do.
I really need your help

actually I would try Odin'ing to the earliest firmware for your device first, as that will likely contain the bootloaders, then you can Odin or OTA to the latest Firmware for your device.
Im quite certain these are low level images/strings (I had to JTAG repair mine for flashing custom bootloader), which are not easily changeable.
If you had to send it back for a refund, I would suggest trying to find the official firmware, possibly including .pit file.
as a last resort... you could have somebody get their PIT file and manually pull those .img's (dd if= , dd of=, etc.) VERY DANGEROUS!
or just unroot and hope they dont notice!

Really Thanks !!
But, I didn't back up my own rom files. Oh my god... T_T
So, I searched pit files and csc file for my device, I didn't get it.
But, I found how can back up pit file.
By using 'heimdall suites'
I'll find p6201 users !!
Really Thanks !!

No problem. You can do it.
And, Can you extract your pit file from your phone ? (Before flashing)
I need file, but you'll be too.
If your model name change, you can't get customer service.
So, you need back it up.
Please help me T-T.

No need posting a useless utube , we already know it won't boot.
Can't help you if you can;t describe what you have done and what you are doing in detail.
Do not know how you got in this situation and don;t know what errors might have happened when you flash by odin. If you can;'t be more descriptive, we're done.

Sorry, i try to explain what i do (sorry for my bad english)
I rooted the tab and flashed cyanogen rom, and the tab works normally for weeks.
Some days ago i wanted to use the tab but happened what i described in the other post...
I didn't flash nothing after cyanogen..

Flashing by ODIN the proper stock ROM should fix everything. Make sure you have the stock ROM for your exact model and country.
Make sure you get a good flash result from ODIN. It must finish and say SUCCESS. Again, make sure you have the correct Stock ROM for your model tab.

[Q] Stock GT-N8013 Samsung ROM

Does anyone know where or even if there are just plain vanilla stock unrooted Samsung ROMS for the Galaxy Note 10.1 GT-N8013 (US variant)?? I rooted and flashed a custom ROM to my tablet and after awhile, I decided I wanted to go back to complete stock. I have seen threads with the original stock kernel and recovery, but I sort of wanted a full, 1gig+ stock unrooted ROM offered by Samsung.. I have seen stock ROMs for other series of this tablet, but I have been unable to find any for the N8013. Any help would be great! Thanks!

Sammobile.com has it, but ics only.

Go to www.samfirmware.com and select the firmware tab. Once you enter your tab details, the available firmware is there to download.
Install with Odin and you'll have your stock tab back.
I did that recently having installed the UK JB firmware, but managed to get a binary count of 12 (increased by 2 per flash)
Now I am back to standard and waiting for the official OTA upgrade *yawn*
Good luck

Goto samsung-updates.com/device/?id=GT-N8013 CMA3 v4.1.2 date 09.01.2013

I just want to point out to stop any confusion, GT-N8013 US country name is cellular south (XAR) and not United States.
Also, here is the link for sammobile:

Can't Get Firmware
Unfortunately, SamFirmWare.com won't let me download the firmware. It asks me to log in, and I do. Then when I go to the Firmware page, it forgets who I am, and tells me to log in again. It doesn't forget anywhere else, JUST on the firmware page.
I tried setting up another account, but they want my credit card info for that now, and I ain't giving that out!

I know that this is the name of the file you are looking for. Do a search for it and this will get you back to a stock ROM.
I know because I had to use it once to recover a quasi-brick issue on my tablet.

Israel:good:

Not exactly what you're looking for but this one is all stock, latest firmware except it is deodexed and retains root. You can re-odex the ROM if you want. Been running it for a while now and it's been pretty damn good.

Here is the download link for N8013UEUCMI3_N8013XARCMI3_XAR.zip, it is the latest factory firmware for the GT-N8013 USA version http://terafile.co/03043e576832/N8013UEUCMI3_N8013XARCMI3_XAR.zip
When the page opens you will see a clock for wait time, click on "Regular" and then wait your 10 seconds, enter captcha code and download file.
If your coming from root clear firmware counts with Triangle Away first, then do your firmware flash then a factory reset after firmware install.

It's only needed to reset the flash count, if your not worried about the count and or out of warranty then you don't really need it.

so do I put it in the root of the internal storage and then ....go into recovery mode and flash with Triangle away already installed?

As stated in post #14 above......
Install Triangle Away first then run the app to clear firmware counts.
Connect tablet to a PC via factory USB cable.
Boot tablet into Odin mode, start Odin app on PC and in PDA line direct the app to the N8013UEUCMI3_N8013XARCMI3_XAR.zip
file and press Start in Odin app.
After restart do a factory reset from tablet recover mode.

if you download your stock rom from sammobile or samsungupdates, it will include only the necessary files. if it includes a .pit, use it, otherwise dont. (usually there isnt one)

how did you update to 4.3? if its a custom rom, you can just flash 4.2.2 again, then install the rom. if its by ota or kies, install 4.2.2 and update the same way again.

I dont think its a custom rom.. After i bricked my old motherboard i bought this new one from ebay.. It had 4.3 pre installed from OTA update i think.. Then i rooted the phone and kept getting the "system ui" error, then i unrooted the phone and hard reset it, didnt fix the problem. So im trying to flash UCUEMK2 which my phone already has.. 4.2.2 has many bugs and i cant send apps to memory card in 4.2.2 thats why im trying to get 4.3.. Thanks

well, you can try without the .pit, if it dosent work do it again with, its simple. if you brick it, then use the 4..2.2 to uynbrick then try the other method, so no matter what its not a biggie.

Yeah if u hard brick it, the phone doesnt do anything.. Not even charge or flash a light.. Its just completely dead.. You could get it unbricked if ur living in USA or UK and few other countries using JTag method but in ireland they dont have the tools to do it, not even the samsung repair shop, so i had to buy a new motherboard.. Thats why im very scared to do this..

I bricked my S7... can it be fixed?

So I modded the hell out of my stock rom and eventually broke it. After failing to flash the stock firmware about 50 times I gave up and put Lineage OS on my phone. Eventually I decided I wanted to try putting the stock back on and somehow screwed up my IMEI crap and don't have a backup. Basically all my phone can do is run stock rom but without any mobile network support or the same thing with Lineage OS. I've spent hours trying to fix it but nothing's worked. I checked just about every guide I've been able to find and none of them work. the issue is either not fixed or there's some kind of an error/change during the process that makes it so I can't continue. I downloaded some combination file that is supposed to help fix the issue but it won't flash via ODIN like the guide says so i can't do that.
I really need this phone up and working again. Anyone got any ideas? As of right now I have a paper weight that I can browse the internet on.
Update: I fixed it by flashing Android 8.0.0 firmware onto my phone instead of 7.0.0. I'm not sure why that fixed it because even lineage OS couldn't get my IMEI number but it's working now.

Quickest way to solve the issue as you've found out is to flash latest stock for device. Bootloader was the source of your problems, once upgraded it cannot be downgraded no matter what. All these bull sh1t guides saying you can just end up with a bricked phone.
Now BACK UP your EFS partition so this doesn't happen again.

I am planning on install a One UI Based rom on my S7, my phone is running stock without any rood or something like this.
How to flash the Rom without making a stupid thing that will brick my phone? i mean how to start all the process from zero?
And another thing i wonder about, what is the IMEI thing that you guys talked about?

1. Go here to download TWRP an install it via ODIN,
https://twrp.me/Devices/Samsung/
2. In TWRP select backup and choose only EFS and back it up to your external card (preferably also to your PC)
that will backup your IMEI etc
