Hi!
I flashed my P1000 Tab to Firmware 2.3.3 from Overcome before I sold it to a friend. He now wants to resell it on so I want to reflash it back to a standard Samsung ROM so they in turn can do updates in Kies etc.
What is the easiest way to do it - go back to a factory ROM?
I have had a look on Overcome and they say to go to the samfirmware site but I'm not sure which one I want as I seem to be going around in circles.
The tablet is in Australia so it would need to be a ROM for Australia.
Can someone point me in the right direction of what I need to do and where I get the ROM I need etc?
Thanks

Not sure where you'd find one but there were Roto backups of the Telstra ROM floating around somewhere. I don't think theres any ROM dumps for Optus (I've been looking for one for ages) anywhere, but you might be able to try using one of the stock Euro ROMs and see what Kies will do with that.
Remember, however that neither Telstra nor Optus ever released a Gingerbread update and are unlikely to at this point, so Kies probably won't be all that useful.
Hi
So I downloaded this files called P1000NUBJP7_UUBJP7_UBJP3, but now dunno what to do.
Do I install it via Odin somehow, the file above contains a PIT file and also a .rfs file which I guess is the firmware as it is 250Mb.
When I try and add the item for CSC and PDA in Odin there are none in that archive!
Thanks

I bought a Metro PCS galaxy s4 that has the T-Mobile 4.3 rom flashed to it. I'd like to downgrade to either an earlier Tmobile rom. Phone is currently not rooted. I do not care about the warranty flag. Any advice you can provide with regards to the downgrade, would be much appreciated. I've used ODIN before, but I found out that ODIN doesn't work with 4.3. Please help.
U cant come back to 4.2.2
I'm reading that I should be able to. Folks are referencing rooting and flashing the South Africa region specific 4.2.2 rom and from there i should be able to flash any rom I want. Is that not the case with my version??

I guess you're stuck with trying it & see what happens. Generally speaking, Joku is right, but, if someone claims it can be done using the method in that thread, then it might be possible. If you're looking for a definite answer, ask the person who suggested the workaround in that thread whether it actually worked for them or not.
Hello,
It's been a long time since I've been these to these forums and an even much longer time since I last had to modify any kind of software on a phone. I recently upgraded to an S7 edge on Sprint and would like to know where to find the tools, roms, and files needed to go to the unlocked firmware version for the S7 edge and go back to Sprint's stock firmware if need be.
More importantly, I'd like to know what risks I encounter especially with Samsung's KNOX. Again, it's been a while so please don't flame.
Any information or direction is very much appreciated.
Thanks in advance!

There's not much for roms echoe is pretty nice. It lags pretty hard but theirs a fix http://forum.xda-developers.com/verizon-galaxy-s7/how-to/guide-to-fix-s7-lag-root-s7-variants-t3441715
As far as firmware your somewhat limited as well depending on your current firmware you may only have the latest 935p and 935U to choose from.
P.s you don't have to worry about tripping Knox I've flashed xposed govtuner viper modified Odin tars that failed miserably I'm still 0x0
Thanks for getting back to me vegoja. So as far as flashing the firmware, where can I get the necessary files? I've seen some threads mentioning or linking the ROMs so I think I'm okay there. Also, I think I'm supposed to use a special version of Odin, not sure why. Lastly, where do I get all those other necessary files like the CSC etc.?
Thanks.

Once you flash the U firmware, you can't currently go back to sprint's firmware. Something to do with the upgraded bootloader. But the U firmware is stable and smooth and has good battery performance. You can enable hotspot to without root which is a perk.

935U PI3: https://drive.google.com/file/d/0BzXeLw4AsxZHZlM1OTJZYXBOQW8/view

Hi nghia0423 and Soooperstar,
Thanks for getting back to me. So to make sure I have this correct...I can flash a 935U firmware on my phone and go back to Sprint stock firmware, but it has to be PJ2.
If this is the case, then I have a few additional questions if you don't mind. First, do the AP, BL, CSC, and CP files differ between firmware versions? If so, where do I get those files for each version?
Second, if I go back to Sprint stock firmware PJ2 (which I assume is located here: http://forum.xda-developers.com/spr...rmware-g935p-pe1-official-sprint-6-0-t3414654), will I then be able to follow the standard firmware upgrade path by allowing system updates and going through the standard update process?
Lastly, is there some risk I'm missing or haven't addressed? If I go to unlocked firmware I want to make sure I can always go back to the current Sprint stock firmware.
Thank you again for all the help and information!

Both pathways - 935P firmware & 935U firmware - offer updates via OTA. They're both official Samsung pathways. As of right now, the 935P pathway offers more frequent updates (monthly) opposed to 935U's mostly every other month update cycle.
The most current firmwares on the 935P & 935U pathways are on the same bootloader version. Therefore, one can flash back and forth with no issues. I recently came to PJ2 935P from PI3 935U so I could download the Nougat beta.
The benefit of the 935U firmware is the lack of bloatware which leads to higher performance, smoother UI, better battery life, and easy to add Hotspot functionality.

Hi optimummind,
Thanks for letting me know that I can flash back and forth between Sprint's firmware and the official unlocked firmware. I did have additional questions. Are teh AP, BL, CSC, and CP files different for each firmware version? Where do I get them?
Thanks!
I want to go back to a normal nougat from Samsung. Does anyone know how. Just saying my Samsung is sm-g935f Vodafone UK. Thanks.
Flash the stock firmware in Odin. As for the firmware I don't have your phone so Idk but do a little lurking on the forums and you'll find what you need. You could even flash the unlocked firmware if you want.
If you find any solution, I would be grateful. I am looking also the same.
Hi,
I am trying to flash my SM-G935A AT&T S7 Edge (not carrier unlocked) with the new SM-G935U firmware (G935UUES4CRG3/G935UOYM4CRG3/G935UUES4CRG3/G935UUES4CRG3) that I dowloaded for my US AT&T S7 Edge. I upgraded my S7 Edge to the latest Oreo firmware via OTA around a month ago.
I used SamFirm to download the image to flash. Anyhow, even though I put every file into its respective category on Odin 3.13.1, I get an "SHA256" mismatch error. I've seen some instruction that say to only add the AP file onto Odin and others say to use the prince cosmey version of Odin. What could be the problem? Does the phone need to be carrier unlocked? Is my firmware too new or of the same version? Do I need to use the prince cosmey version? Is it not possible to flash the g935u firmware onto a g935a phone? Should I use another download source? Should I use the slightly older G2 firmware? Anything else I should consider?
Also, I noticed that I could not download firmware for the SM-G935A using the ATT code with SamFirm? Any reason as to why?
I realize that there are many other threads that touch upon this problem but they are either with a different edition of the phone, firmware version or some other variant. I'm posting a new thread because I want to be as thorough as possible and make sure not to brick my phone by receiving safe advice before moving forward. Thank you for your time!
Below are the SamFirm download details:
SamFirm v0.3.6.0

Correct Thread?
Did I post in the wrong thread or something? Is that why there is no response? Would someone be kind enought to point me in the right direction if this isn't the right section for such a question?
Thank You
Hi did you find any answers to this issue? i got stuck on same point as you...
Stock Odin checks the version on the device and fails because the U version doesn't match the A version you are "upgrading". There are patched versions of Odin that skip this check, and that is what you need to do a cross-carrier upload.

Use a patched odin to flash the firmware, it will go through.
