New android on locked Samsung SII Plus - Android Q&A, Help & Troubleshooting

Hello!
You may think this is a newbie question but I haven't found an clear answer to my question:
My gf has an locked Samsung SII Plus - I9105p (locked on Orange - Romania), curently running on Android 4.1.2. It runs very slow so I want to update it to some 4.4.2 found on the internet. Can I do this without sim unlocking the phone, is it gonna work?
*note: the 4.4.2 i'm talking about is not an official Orange - Romania OS. Kies tells me there is no newer version for this phone. Truth is that I heard the Orange team here in my country is very low on human resources so they didn't bother releasing anything new for this phone, and I don't blame them.
Thanks in advance!

Yes, you can update it. I am also using an i9105p locked on orange Romania and i've installed any version of android from 4.1.2 to 5.0.2

[Q] GT P7500 - proximus / belgacom

Hello everybody!
Just subscribed a contract with Belgacom / Proximus for a GT P7500 3G.
Heard of the just released update to HC 3.2 for this tablet but:
1. Kies, when hooked to the tab says "this product doesn't support firmware update"
2. also, OTA, no firmware update available
Does anybody know something more? Is it a problem due to the fact that this tab might be somehow branded and thus not allowed to get "generic" updates?
Or I just need to do something I don't know? (pretty new of android ... sorry)
Many thanks in advance to anyone can help.
Cheers.

[Q] Help required for Noob!!!!

Hi All,
I am new to this forum and new to android world.
I have purchased unlocked Optus Samsung Galaxy S2 (I9100) from Australia and currenlty i am using it in India with Airtel. My mobile is installed with ICS 4.0.4.
I want Offical Jelly Bean firmware in my mobile.
Can i install Official Jelly Bean Rom released in SPAIN? Will it lock the the mobile after i install this ROM?
Or If i need to wait for Jellybean to realese in my region, Did i able to update Australian Version or Indian Version of Jellybean ROM or only the OPTUS version of ROM through Samsung Kies?
Please help me on this request.
Thanks,
Arun Panneerselvam
yes, you can install the jellybean from spain and no it will not lock your phone.
The choice is up to you. You try one of the custom roms on this site or wait for an official version through kies.
Updating kies may not happen this year because the roll out for jelly bean wil be uneven, no one knows what countries will get and when or if they will get jellybean at all.
Before installing you have to root your device,
then check and search on internet for your original rom (it could be useful if you need to send it to assistance in warranty)
If the phone is branded usually official updates came from carriers ,and often they need more time to release update after the unbranded is released since they want to put on it their customizations

What the devil are you talking about? You don't need to root in order to install the stock Samsung Jelly Bean firmware.

[Q] Android update for Unlocked phones

Hello Experts,
I have bought a new Galaxy S2 mobile imported from Korea. The vendor says it is unlocked.
I had inserted my local sim and things are working fine.
The Android version currently running is Gingerbread.
I would like to know how can i update the version to JellyBean.
I read lot of articles and youtube videos on rooting the version, but i am confused and afraid.
My major doubts are, since it is from Korea, should i use the some Korean version of Jelly bean itslef to update.
When I connected to Kies, it says, this firmware cannot be update using Kies.
Can someone please help me here.
Ask in the S2 forums, they will help you better. Surely you will able to update your phone downloading the firmware from samfirmware.com to install it using Odin, but as I said, ask in the S2 forums to make sure.

Samsung Galaxy A9 Pro

Hello,
I got from my GF a Samsung Galaxy A9 Pro (Model Number SM-G887N, if you search for this one you will probably find A8s 2019 phone on SamMobile) with with a provider (KT) branding from Korea. This phone has currently Android 10 installed with the Build G887NKSU2CTI2. I would like to update the phone, but this didn't work on the phone directly.
So I thought about to remove the KT provider branding and install a clean Korean or European Software Build. I'm not new to flash phone (did this a few years ago, but since then a lot changed). I just wanted to ask if somebody can help me regarding the right Software and the possibility to remove the branding.
Can I remove the branding and install a clean SW from Europe/Korea? If yes, what for tools (Is ODIN enough?) and which SW would do I need? I guess there are tons of instructions but I do have a problem to figure out about the compatibility of SW and branding.
Thank you a lot
Android 10 seems like the latest version for your phone. Two OS-Updates done with that.

Hello Zentriks, thank you for the quick reply. I still get updates regarding security, same issue. Not possible to install. Apps also start to close itself after starting. This phone is a total mess. So I really would love to change the SW without any branding.
