I have been rooting and flashing for quite some time now. However, I am fairly new to Samsung devices. I have only rooted HTC devices before. I have a Galaxy Note5 for T-mobile that is the Hong Kong variant. It was purchased with a crappy ROM and I want to unroot, then reroot again to be sure I get a clean phone ready to be used. I need help with unrooting and restoring the device back to its factory state. I have faith in the XDA community to solve this as I am not sure exactly sure what I can do to do this.
I know that HTC phones have an RUU that you can flash that completely restores the phone back to out-of-the-box condition. Does Samsung have something similar to the RUU of HTC? Please let me know what I can do to restore the phone back to its original conditions.

Hello.
I just bought a new Galaxy S phone online. The phone was unlocked (originally T-mobile). The phone has firmware 2.1 update 1. When I run the Samsung Kies utility, it tells me that there is an update for the phone (probably firmware 2.2). If I update the phone will it continue to work or it will become locked again?
Sorry if the question sounds stupid but I am a newbie to this and I don't want to mess something up. Is there a way to backup the existing firmware so that if anything goes wrong I can restore it?
Thanks
I recently purchased the G920t factory unlocked version on Amazon. I rooted it and installed a custom ROM. I was hoping that someone could help me out with finding the stock firmware for the factory unlocked variant. I believe it is slightly different from the standard T-mobile firmware, as it didn't include any t-mobile apps, etc. The reason I was asking is I've been having call quality issues and wanted to flash back to stock to see if it would be resolved, but didn't want to flash to the standard t-mobile stock as I believe it is slightly different. I know I should have made a back up before flashing a custom ROM but I failed to do so and am now trying to fix the issue afterwards.
Thank you so much for any help you can offer.
What firmware was on it originally? What baseband?
My USA factory unlocked 920T shows a baseband of G920TUEU3COK1 after the latest OTA update was installed. XDA rules don't allow me to post links to SamMobile firmwares. You can search their site for "920T", but don't used the "SM-G920T1" search result. The proper firmware has "Cellular South" as the Country/Carrier.
Thank you so, so much. So that'll allow me to roll it back to the way it was right out of the box?

yes, but I don't think it'll reset the knox counter to zero.
can I flash Canadian firmware (SM-N920W8) on a SM-N920T from t-mobile?
I find it hard to believe nobody can answer this question.
I am with Rogers but purchased the phone outright as a refurb and would like to take advantage of their wifi calling but cannot with t-mobile firmware
How about changing the CSC and if that is possible, how to do?
guess not huh?
I'd love to get an answer to this question. I bought a Note 5 that was originally TMobile and now I'm using it in Canada on freedom mobile. The phone was working great until a few weeks ago when I tried to remove the root that was on it and now I'm stuck in a bootloop. I've tried to flash the N920W8 firmware from Canada but it fails... the backof the device says N920W8.. but when it connects to twrp it says its a N920T.
Guess I should try the 920T firmware with odin... ?

Did you wipe system?
i would like an answer as well. have a note 5 bought here in Canada that was branded tmobile. but unlocked. tried flashing a rom and have had nothing but problems with imei/csc/service with sim card ever since. flashed stock n920t firmware 3 times with 3 different up-to-date firmware files and it hasn't fixed the issue. oddly enough i found out the number on the phones back is actually n920v so it's been rebranded once already. apparently because all phone info and twrp say it's n920t . will flashing Verizon firmware fix this? also if it's already been done once why can't i make the system n920w8 instead of n920t? how was it done than? or can i flash international rom ? really need to get service/imei/baseband/csc in working order. i can't afford a new phone .... so many questions...
Morning All!
I am getting ready to file a claim with Samsung Complete Care for a cracked screen replacement. The Note 8 was originally an AT&T branded that I flashed over to Verizon firmware and then rooted. Do I need to flash it back to the original stock firmware or can I leave it as it is? Will I receive the same phone back?

Not exactly the same, but I had to send my Note 8 in for Warranty Screen Replacement for Burn-In. I did receive the same phone back but I was advised to wipe it before sending it in, as they have an entire QA process once repaired to warranty the work. I would suggest flashing back to stock FW and definitely unrooting it, to avoid any issues once there. Good Luck.
