Hello all! I've got myself a dandy Galaxy 9 plus from America that cannot be rooted (sm-g965U), I'm told it is impossible to root this phone. I am also told something referred to as a bootstrap cannot be loaded except the 'stock' one that loaded the last cycle. So, my question to the experts is what, short of a new phone (currently researching older models), is needed to achieve either/or 1. Custom ROM? 2. Rollback Android? I would like certain features unavailable in 9 and 10 to be restored. And, I am told this is not possible as long as 9/10 are running the show.
Lastly, my apologies, I wanted to get some expert advice from this site. I suspect that much like in the name Boy Scouts, you know you should probably be a boy, I suspect I should also be a developer to be here. I'm not. (in case you were on the fence (wondering)). Cheers! Weeee!

Hello,
I would like to buy the cheapest tablet I can find. I found an eBay insertion featuring a Chinese tablet running Android 2.1.
While I wait for the seller to provide me (if known) some information about brand and model name to find more information about this device, I would like to ask a couple of questions that might sound stupid a little for you experts, but as I don't know much about the Android OS I'm still going to ask (if this was WinMo, I already knew the answer was NO)
1. Is it possible to upgrade Android to a newer version, ie. Gingerbread or even Honeycomb, on any device that supports it? Like, some kind of software upgrade tool? Or, how could somebody make an upgraded ROM without spending months in reasearching, experimenting and breaking?
2. Is it possible at least to root devices like the one I mentioned?
Thank you
Hi,
So, I am buying a new tablet soon, and I will be giving my Nook Tablet (8GB) to my 7 yo nephew. I want to find a ROM that satisfies the following conditions:
1. Supports Japanese (not just a keyboard to type but as a system language)
2. Stable without any issues (he lives in Japan, and I live in U.S., so I won't be able to fix any issues for him, so I want to make sure it's a very stable ROM).
3. Doesn't have issues with Google Playstore (when I searched and read through some ROM's threads, I saw some of them having compatibility issues with apps)
4. (preferably) based on newer Android builds because nobody around him will know how to update it, so this ROM will be the last ROM this tablet will ever use till it dies.
If you can think of any ROMs that satisfy the above conditions, please let me know. I very much appreciate your help/input in advance.

I recently got a Kindle HDX and I despise the way the store is laid out.
I want to install Google play but of course amazon took away that freedom so everything is purchased through their market... I've never owned an android before and don't know any technical guides, but all the easier ways/ways I understand are for earlier versions, and with forced updates Im at the newest version which apparently cant be rooted. If someone could explain how to:
1) Downgrade / regrade my kindle
2) Root the kindle
&
3) Get the google play store in terms I could understand, it would help alot.

You really need some Android experience to pull off the required steps without bricking your device. My recommendation to wait for a solution to come to the level of firmware your device is running. If FireOS (Amazon Store) is too unpalatable suggest returning your device and pick-up a Nexus 7 instead.
I also recommend avoiding 'hacks' that allow installing Google Play/Services on FireOS. Problems abound. You can obtain the current version of many free android applications from other marketplaces such as 1Mobile. It is an imperfect solution but better than the alternatives IMO - especially for inexperienced users.
I'm thinking about getting a HDX 7 with the current firmware. Just wanted to ask whether or not it is currently possibly (or work in progress) to install a custom ROM ? If not, I won't buy it.

Yes, but the process is tedious and carries some risk. If successful you have the option of Nexus v4 or cm11. In your shoes I would look at something else.
First, please forgive me if this is the wrong place, but this is the General Forum, and the forum software has changed a lot since when I was really active here as an active phone modder and active poster!
So like I said I've been away from the forums for a long time... trying to rereading a lot and trying to get back into MY PHONE.
I hate my modem sometimes because T-Mobile just sucks in some areas and is great in others [Greater Houston Texas Area, but mostly south side and towards the Galveston Bay].
I would like to know if the newer modems are interchangeable with the below config on my G900T?
And if there is any advantage to upgrading my modem? Wondering what modem I might be able to upgrade to with that below config and if there would be any advancements/pluses/gotmeinabadways/or other things I should be aware of if I did?
Also I'm wanting to upgrade to Marshmellow maybe, should I or should I just forget it? I will be reading more about the ROMs available. I've read a lot of posts about how buggy 5.1.x is. So I don't want to even go there...
Basic Phone info, Stock T-Mobile ROM [Damn bloatware] rooted awhile back with I think towelroot. I would really like to change to a slicker ROM that is debloated and maybe deoxed maybe. Will have to read hella lot more about that for sure..
Model SM-G900T Rooted
edit: Nova launcher
Android 5 not 5.1.x
BaseBand G900TUVU1D0B1
Kernel 3.4.0
TWRP 2.8.6.0 recovery installed
Broken Xposed :crying::crying::crying:
Can anyone recommend an app that will give modem info without having to decipher the baseband? or is there a very good break down of what each part of baseband means? I know go search!!! and I'm trying to reacquaint myself with the forums but the newer software is far different than I remember EKK! And search always hated me!! And even the different forum headers have changed due to time marching on and me being well Techtarded the last year or more due to things better left unsaid...
Have Xposed installed as noted above, but its been f00ked for a long time due to the ARM processor if I remember correctly and the Framework installer not being compatible..... Wish I could used the Xposed but........ I originally got into Xposed due to the Hex icons I actually paid for Xposed because I liked and used some of the modules made by smart people. Again but!!!

The most recent firmware and modem for the TMo S5 is version OL1,that came out in late December.
muniz_ri has been nice enough to put together a ROM that is the Stock ROM, already rooted, and ready to go:
http://forum.xda-developers.com/tmo...t/how-to-update-to-g900tof6-5-1-1-pc-t3141404
There are links there to the ROM, including the modem, or just the modem files themselves.

@daspazz the following website has decent basic info that seems to address the questions you ask: http://androidmodguide.blogspot.de/p/other.html
TLDR: yes modems are interchangeable
As for Marshmallow, I'm pretty sure for now, since there has been no official 6.0 update yet, you'll have to go with Cyanogenmod 13 (or one of the variants like Bliss 6.0 or Resurrection-Remix), they're in the unified development section (our phone's development codename is KLTE).
As for deciphering the baseband, look at the last three characters, let's assign them generic letters XYZ. X is the year (M being 2013, N being 2014, O being 2015, P being 2016, etc.), Y is the month (substitute the actual letter for its position in the alphabet), and Z is the revision number. So taking the most recent firmware (G900TUVS1FOL1) as an example: OL1: O means 2015, L means December, and 1 means 1st revision. Another example, build number G900TUVU1ANE6: NE6: N means 2014, E means May, and 6 means 6th revision.
It seems to me there's been some consensus that the most recent modem (which rlichtefeld linked to in the post above mine) is the best
Much Thanks!!!!
@rlichtefeld and @thisisapoorusernamechoice
I really appreciate the information gentlemen!!!! I've been reading through the info you both provided.
I did flashed my modem (only) to the newest one, G900T_OG6_Stock_Modem.tar. Ended up having to flash back to the modem for 5.0, G900TUVU1DOB1-MODEM.tar, because I literally could not hear anyone when I made or received calls.....
Also had to used Odin v3.09, because v3.10.6 wouldn't recognize my phone. Strange that!!
This ADB installer was very helpful!! It fixed problems I was having on the PC I was using to flash my phone. Much thanks to @Snoop05 for the ADB installer for the PC. It keeps you from having to install the full SDK for Android.
Thread moved to proper forum.
Hello,
I recently acquired a refurbished S9+ and as many other people, I realise now that someone must have been messing around with the internal software. This is my secondary phone so it's no big deal but I would like to understand what was done on it nevertheless, and maybe turning it back to a cleaner state, if possible, and if it has not too many drawbacks.
-apparently, Samsung Pay is not working. It hangs indefinitely on the screen where you must choose the type of security.
-when looking into the Play Store settings, the device is not certified
-WiFi calls apparently are unavailable
-OTA update is not working (nothing happens when I try to check for an update manually. What's more, no information about the last update is available. By the way, the phone software is outdated. (last Android security fix is dated from Feb 2019)
From what I read, it looks like the CSC was modified, right ? Would it be a good idea to change it back to original ? (I may need some guidance about that but we are not there yet) Would such a procedure restore, for instance, the OTA update feature ?
(see pictures attached - there is what is written on the phone's back cover too, if it can help)
Thank you very much in advance. Please tell me if you need some other specific screenshots.
PS : I also bought a Note 10+ from the same refurbisher and it ended up being a Korean model. But the firmware seems clean. I know Samsung Pay won't work in France, WiFi calls either, and I will be stuck in "LTE" 4G instead of 4G+ but at least OTA updating is functionnal (I got an update a few days ago) and honestly ? That's fine with me for the price.
Anyone ?
From what I've read researching on similar issues, the previous owner who messed around with the internal software must've flashed custom firmware on your S9+, and probably tripped Knox (and is why your Samsung Pay app won't work). According to some developers on here, you're able to hide the fact that you've rooted the phone, but I don't think you can un-trip Knox once it's been done.
Prior to your post, I didn't know a single thing about CSC and I'm not sure how it's really relevant when flashing a mobile device (unless it's carrier-related), but I think all that's required when flashing a device is the model number. Luckily, I stumbled upon a thread that is actually your exact, same model! Do what you please with it, and I hope I helped — I'm not a professional, nor am I really knowledgeable about all of this stuff, but I'm trying.
This is the thread I was talking about:
Official Stock Firmware Thread (11 August 2022) - Galaxy S9+ (SM-G965F)
UPDATE (7 APRIL 2022): Samsung has officially declared the Galaxy S9 and S9+ EOL. They will no longer be supported, and FVB4 will most probably be the final build for this device. Latest stable firmware: G965FXXUHFVG4 / G965FOXMHFVB4 /...

You're welcome! Was it what you were searching for?
Not sure, but I hope it will help me understand the firmware/CSC stuff better
Alright so apparently this phone actually is a SM-965N, judging by what is displayed when booting into download mode.
Unfortunately I only saw this after starting a flashing attempt with Odin and now it's stuck at "system.img" so... I'm gonna let it run a few more hours but...
It's most likely bricked at this point, isn't it ? (edit : interestingly, after I forced-closed Odin and reboot the phone, it was not)
If you ask me I find this kind of "refurbishing" a little bit sketchy to say the least.
