Hi, I'm no stranger to flashing custom ROMs on Samsung's. Been doing it to s3, s4, s7 and the s8 amongst having a plethora of nexus phones that went back and forth with Android pure or Los.
I plan on upgrading the software on my t805w to marshmallow since never received the update ota.
I also would like to install the UK BTU image as its my go to for stock firmware. Also I don't want to erase the data already on the tablet so I'm guessing in going to be using the home CSC.
Would someone please list what I need to flash so I can install the latest Canadian BL, Modem and then the right version of the UK android image without wiping my data.
I hope this would also remove any stock bloatware left over from the carrier on 5.0.2.
If this proves a pain to wipe without clearing data then I'll guess I'll go down the route of twrp and BTU flash then magisk to debloat BTU further with Titanium backup
Cheers

Okay, I'm aware that we're able to flash GT-N7105, AT&T, T-Mobile, and other GSM ROMs on our phones, but would it be possible to flash a completely stock one (from one of the variants) via ODIN, flash the proper CSC and modem and the device status not be "modified"? Also, if so, would it be possible to receive OTA updates, then (because I assume it'd be necessary), reflash CSC/modem as updates roll out?
Or should I just shut up and try to get an authentic GT-N7105? -____- I just want one that doesn't have bloatware, a SIM lock, and can be updated as often as they're rolled out. I was playing around with the aforementioned idea on my backup T889, but I don't know enough to come to a conclusion. I'm running a GT ROM, flashed the recovery back to stock, and unrooted, but it still says modified, so....
Anyone?
OK, I will be going to the UK and want to keep my ATT Note 8.0, also I have already flashed a UK ROM on my 5110 with success.
Knowing that ATT version has locked boot loader and other differences... Kies for example won't allow backups of Applications, as there is no option for it. But the 5110 has the option available.
Is it possible to flash a UK based 4.2.2 ROM over the stock ROM?
Odin or Kies?
I know I can root, but rather do it after new ROM has been installed.
I am not very much familiar with all intricacies of Android system but i have played around rooting and putting customer firmwares on few devices.
I have AT&T Galaxy S3 with following detals:
Baseband: I747UCUEMJB
Version: 4.3
I had the device rooted in the past but recently un-rooted it and reset the flash counter as well and did factory reset. Did all that since i wanted to use ISIS and couldn't make it work on a rooted S3. Seems it used to work before till they updated ISIS app to patch it.
Now AT&T got 4.4 update and my phone detects it, downloads it but while installing fails at 32%. I have seen many threads where people faced similar issues due to their phones being rooted. Seems something on my phone didn't reset to default.
I found one post which mentions that i can download UCUEMJB_to_UCUFNE4_Firmware_update.zip and load it to phone using TWRP. As i understand, this will update the baseband but android version still remains at 4.3 (?). Is that the path i should be looking for or i am shooting in wrong direction? I want to stay on default firmware since i like to use ISIS till they keep running those cashback promos
Would appreciate some feedback.
Download MJB firmware (thread in General) and flash with Odin. You can stop there or try the ota again.

Thanks for the reply.
Just to confirm so that i don't mess up, i will apply the following(is modem same as firmware?) and then try OTA.
I747UCUEMJB: modem_CWM_I747UCUEMJB.zip
No. The modem is only one part of the firmware. Firmware includes bootloaders, kernel, system, modem and more.
Hey guys,
little issue here, hopefully somebody can advice.
Phone is S9 F-Version (XSG CSC) rooted with SuperSU.
I download the latest firmware update via sammobile and have AP/BL/CP/HOME_CSC files. I download for XEF but from what I understand XSG/XEF/and certain others are OXM (multi CSC)-files, so the CSC doesn't matter, right?
I flash them with ODIN but my user-data is always gone. Not a big deal since I backup everything before, so a quick restore user-data partition and I'm all good, but its annoying.
Also everything that is NOT stored on this partition is gone as well and since I can't restore the system partition without going back "pre-update" this is more of an issue.
Is there any way to flash the new firmware without having those issues and without having to restore stuff after?
thanks
I have the same question as OP. How to update without losing data when rooted?
Can I flash this variant (SM-G990U) over to the ATT, or even a stock unlocked firmware?
The goals are to enable WiFi calling, and remove the metro splash screen.
I cannot root the device as my work requires official firmware.
I am open to suggestions on what is best. I have not tinkered with flashing in quite some time.
U could try to root phone and use safynet fix if your apps requie official firmware non root. if you have (when i check model) standard S21FE phone with branding from ATT (?) you could flash stock rom with odin. I don't know where u from but you could flash your stock firmware for example for spain distribution.
I was able to flash the phone with stock firmware, changed csc to ATT and all works well now. This place has gone downhill. I remember when almost immediate replies to help. Now, not so much. Thanks for trying.
