I want to upgrade my Galaxy S3 that i got second hand from someone, but i have had a very hard time finding a way to do so due to the phone's model type. The phones model number is SCH-R530x, I have no knowledge of who the phone's carrier was, but i have been told that it is a generic unbranded cdma without LTE version, carried by nTelos. I was told to check here for help with it, I want to upgrade the phone to where it can download and play Pokemon go so 4.4 kit kat is fine if that's easiest route.
Anyone at all? i really want to figure out how to upgrade my phone.
Did you get the model number from download mode? Search for the latest stock rom on sammobile.com.

Hi,
Bought a Samsung Galaxy SII (SGH S959G) and flashed it, unlocked it (before January 26th (which was legal back then(and I am using Ultra Mobile as my carrier and rooted it.
The thing is that now it's an SGH S959G (Straight Talk phone) that has an OTA update and when the download starts it says it's downloading the new version for this phone, but, when I browse to the "About Phone" section of the settings, it says that the Model Number is Samsung SGH - I777 with a baseband version I777UCKH7, Kernel version 2.6.35.7, Build number GINGERBREAD.UCKH7, AND, when I power on the phone, the splash screen shows that it's an GT - I9100.
Today I connected my phone to Kies and (obviously) showed that an update was available for I777 (Android Version: 4.1.2 / Baseband Version: I777UCMD8)
My hands are itching to upgrade my phone because when I bought it and rooted it I had JellyBean in there, and now I have Gingerbread, but:
Should I upgrade my phone?
I want to keep root on my phone, will it be possible?
Will my phone still be flashed?
Will I loose the unlocking that I did to the phone?, I really just don't like the service at Straight Talk, besides, Ultra Mobile is much cheaper.
Now, one more thing, this phone was not activated on any network when I purchased it (got it at craig list (for those who know what that is)), checked the IMEI number and was not reported either stolen or lost, but couldn't register it with Straight Talk since I didn't have the original purchase ticket from WalMart, so I had to change the IMEI number on it too ... will I loose this if I update it?
Thanks, in advanced, for your help, sorry it's such a long explanation, but just wanted to let you know the whole story so you could get all the facts you need for helping me, and if you need more, please just let me know.
Again, thanks.

Thanks samprocat, to unlock the phone, first, I downloaded an app from gogle play store that actually stated that it unlocked the phone for me, then I sent the phone to someone to change the IMEI number (I looked my IMEI up on the IMEI black list on the internet but it wasn't black listed but a message kept popping up stating that the phone's IMEI was not registered) so I don't know how they did the IMEI change, except, that they did change the IMEI while the phone had the sgh s959g image on, but could not put on the modems, that's why they used the I777 image.
I know that if the phone gets back it's original IMEI, it's not going to work anymore, plus, I don't know if it's going to stay unlocked either. To tell you the truth, I don't want it to go back to it's original state. If there's a chance for me to loose the phone's unlocked feature, or get back my original IMEI number, then, I'll just stay with the phone this way.
Hello. Very quick question I'm hoping someone might be able to answer definitively. I picked up a Galaxy Note 3 Neo today (model SM-N507) which is the Taiwanese version. It has only been updated to 4.3 whereas some other territories are on 4.4.X. My question is, would it be possible to flash one of the Official Firmware builds from Sammobile and NOT risk bricking the phone?
For example, in the event that the flashed build has different LTE bands, would a problem like this actually brick the phone, or would I (theoretically) be able to use it, just without LTE? I am willing to experiment so to speak, so long as it doesn't actually prevent me from using the device.
In the past I had purchased a Hong Kong Galaxy Tab 7.7 that wasn't updated to JellyBean and flashed a Malaysian Firmware without a hitch, but in said case the model numbers were the same. With this, I would be flashing SM-N505 or such.
Any help would be appreciated, thanks.
i have a Verizon s4 . its unlocked. i am using it in india . i cant find any lollipop firmware without Verizon carrier . how do i upgrade my device to 5.0 ?
I'm guessing you want t update to lolipop but can't because Verizon isn't in India? There's Muniz's rooted stock OF1 in the general section.

thank you for your help i am new to flashing . can you give me link please . i don't know what is munzi or of1 . . can i flash it with Odin ? is it safe like original roms?
are you rooted? If not could you tell me which build number your phone is currently at?
As for Muniz, he's a guy who works on rooting our galaxy s4 =)
the latest build for verizon galaxy s4 ends in OF1. it is Android Lolipop, 5.0.1
his instructions are here.
you'll need root to follow the directions.

from the looks of things , this looks risky . i would rather have a unbricked s4 without lollipop thanks for your help. is it possible to root s4 with iroot ?
It's not really that risky.
best way to root kitkat Verizon galaxy s4 is to use towelroot with NC5 build kernal
Verizon's Galaxy s4 is supposed to be unlocked by default, its just rooting is an option just in case you dont like the look of the s4's lolipop. if you want just complete current stock lolipop build OF1 you can download it here and use ODIN to flash, or just use Samsung kies software.
just so you know if you use the sammobile method or kies method to update to lolipop, you cannot go back down to kitkat. Muniz's method with root allows you to return to kitkat builds if you so desire.
by the way what happens when we flash a rom with carrier to a unlocked phone ?

wait a minute . the link you just send me . . isn't it a rom with Verizon carrier . my phone will remain unlocked if i flash it ?????
You do realize that Verizon phones are supposed to be GSM unlocked by default due to some agreement with FCC for their bands?
From here
Unlocking a Verizon phone
Even though Verizon uses CDMA instead of GSM, most of Big Red’s devices come with an unlocked SIM card slot. According to Verizon, its 4G LTE devices aren’t locked and, if you want to bring one of them to another carrier, there is no code needed to program the phone to play nice with it.
However, even though SIM-equipped Verizon phones can be used on AT&T, T-Mobile, or other GSM carriers, the phone will need to have roaming GSM radios in order to make phone calls and send texts in the United States. While most recent Verizon handsets will work just fine on American GSM bands, your mileage will vary when it comes to LTE support.
Even though Verizon doesn’t have an online unlock request, you can call 1-800-711-8300 and request a SIM unlock.

sorry for my lack of knowledge . i didn't know that . i bought it from my friend . i thought it was locked by verizon and he got it unlocked for Indian sims .
well, then the choice is yours, you can root your phone and use muniz's method to allow you the option of going back to kitkat if you desire, or just use normal methods like samsung kies to update normally, which will lock the bootloader so you can't downgrade.
As for me, I'm going to(try to) sleep. 3 AM here X(

thanks buddy you were very helpful . my last question what happens when we flash a rom with carrier to an unlocked phone .
well... if it was one of those international versions of the galaxy s4 like the GT-I9500, then you'd probably brick it by flashing a rom for a carrier version like the SCH-i545. or at the very least softbrick it.
I think unlocking phones is something more hard coded than the rom itself. cause, even if for example you have a att phone unlocked, it still has a att rom, and should be able to update the rom while using an att sim
though in your case, I have a feeling whoever "unlocked" your phone never bothered anything other than change the APN settings to that of whatever Indian carrier you were using.
your phone shoulnt have any problems with flashing an update via kies.
check your build number under settings> more> about phone. if they match any of the PDA here, you're on stock. using network signal info app in the play store can also tell you the build number (build ID) and bootloader.
though if your phone doesn't say "custom" when you boot it from power'ed off, that you're probably on a stock rom with no root
Hello everyone first time posting on her, anyway my brother in France sent me a Galaxy s5 it was running lollipop 5.0 so naturally i wanted to upgrade i did a manual update search but it said that's the recent one so i took a look under the battery and the stickers says my phone model is SM-G900T but when you boot in odin mode at the top it says the model is SM-G900P so i got confused after that i went to sammobile and downloaded marshmallow for both models and tried to flash them m. The T-Mobile's one failed odin said something about authorization but the sprint one went okay the phone works okay great in fact i rooted it and everything exept i can't get 4g to work only 3g i searched in the forums and found out about unlocking band 3 but i have to have an MSL code or something and i have no idea how to do that. The phone is unlocked by the way i live in Tunisia and get data and calls fine so my questions are
1- what's the correct model of my phone?
2- how to enable band 3 so i can get 4g on my phone?
Any help would be appreciated thank you guys
HI, I switched carriers yesterday and my S9+ still appears to be on AT&T software. Is there a guide somewhere that shows you in detail how to get the T-Mobile software on it? I'm not very knowledgeable in flashing, but have seen around the site that ODIN is a solution? Thanks
edit: I know i need to get from U to U1 back to U i'm just not sure how
