[Q] Why we don't have more custom roms for our p6200/6210 device's?

I am sorry if this is stupid noob question, but why we don't have many custom roms since that our device's sharing same exynos 4210 hardware, like Samsung galaxy SII?
I own SII for myself and there is every day something new in development thread, and here nothing
My P 6200 is crying for fix WiFi problem and some great custom rom :crying:

I have been using Android since it was released and have collected various devices. This is just me, there is nothing better than stock rooted and tweaked rom. Just debloat the rom and you will be ok. My P6210 is amazingly fast with NO error or any single issues. I got both apple and Samsung products and my P3113 and my P6210 are my main tab. It is a must for me to go stock rooted and tweaked. Just me.
Cheers

I always asked myself the ssame question too... but it turns out we dont hhave so many devs here and this device wasn't a hit like the S series from samsung. Making custom roms isn't so hard but it needs alot of learning if ur a biggener. I tried making custom roms myself but what else do u need from a custom rom if you already have CM9, cm10, paranoid android and soon to be AOKP? But who knows we might see new stuff I mean I bought this tab before there was even a functional cm9 build and I was thinking of selling it. But it pulled through aand I must say his device is rock solid we just need to nail the wifi issue.

I had wifi problems as well on stock ics (UK version).
It all disappeared when I flashed the US version, give it a try...
This said, cm, aokp and stuff are nice but not stable enough for my taste yet, I don't like bugs (I am not a very patient character) and for me so far there's nothing like a good home tweaked, rooted and deodexed stock ics rom.
When cm10 is completely stable then I will eagerly flash it, I check xda every day waiting for that day to come

I have actually did a lot of things with the ICS stock rooted but never have wifi issues. Anywhere I go with wifi access, I never have problems or any issues. Would it be router related? With my P3113, its fine but with my YP-G70, there was. I have to install another stock rom to solve it. Otherwise, everything works fine with me. These products are actually very nice IMHO. I'm just waiting for the JB update for my P6210 and P3113, if there will be.

Early in ANdroid the stock ROMs were often terrible and there was a lot of room to make easy improvements. Now the stock ROMs are really quite good and there is not much that can be improved on easily. IF you like a different style you have the CM based ROMs with some UI differences but not much in the way of performance improvements and you lose stability and some hardware features like IR Remote. Even with the Nexus, by the time some individual developer takes the time to customize a ROM, Google has new features out in the stock ROM so its just not worth it to build from scratch.
SO called debloating is mostly a placebo because the new devices like this tab have lots of memory and apps you don;t use aren't doing anything or taking resources.
Curious to know if you have found anything unique and useful in SII development. TO me it seems like all retreads of repackaged stock or CM based stuff with a few different apps from samsung or sony thrown in for good measure.

Stock rom is full with unneeded application.
Custom rom bring more speed and space.
I'm currently running custom rom based on JB leak on my Samsung SII, which is full with super functions from S3 and Note 2. Above all that rom is great for daily use For me that is enough

Does this phone just hate custom ROMs?

I don't see many options here. Mostly stock roms in this forum topic. I had a ton of problems with boot loops and such and just couldn't get anything to work. OTAs still force a bootloop sequence unless I zero out: "/dev/block/platform/msm_sdcc.1/by-name/misc". I just disabled the notification for them and everything is fine now, but I was wondering if there was any point to using anything other than the stock ROM.
I kept root and just removed TMO bloatware. The 4.4.2 stock ROM seems pretty damn fast, but I have nothing to compare it too. I'm basically just trying to decide if it's even worth it to attempt another ROM install. Are there any real advantages to any of the other ROMs out there over stock? I'm looking for stability above all else, then speed. Features I don't really care about.

Stock or at least stock based with dorimanx kernel is about as good as it gets for tmo...most of our developers have moved on to newer devices...and non tmo roms don't have Wi-Fi calling

yeah wifi calling is irrelevant to me, but frankly this stock ROM is amazing compared to the performance of my Relay 4G.... H/W keyboard android phones RIP.
Cheers

I have the Intl version which sports more custom roms but they are all the same more or less.... im on stock KK too even though i was a die hard software updater (had 5.1.1 on previous Nexus 4).
Have to agree with you this phone hates modding and is really feeble, it will get bricked quite easy unlike the Nexus 4 which can take a lot of abuse

Try the new cloudy rom. It's a port from LG G4 with various elements.

why dont you guys check in the G2 Android Development. most roms cover all variants there.

For me CynaogenMod's Privacy Guard feature is a must-have on any Android phone. But right now I'm finding that the official CM12 nightlies seems to screw up the modem settings for my local carrier here in Canda (Wind), so I lose access to the service. Constructive suggestions will be greatly appreciated.

Guide to root S5 from Lollipop to Marshmallow

Hi. First post and I have never rooted a phone before.
My S5 is a G900F on EE network.
It has an issue where after switching to wifi it cannot switch to mobile data without a restart hence I restart it about 3x a day. Every day. This appears to be an issue with EE on the S5.
The phone is unlocked and I'm not with the EE network for my calls.
I would like to get rid of any trace of EE but also would very much like the sound of marshmallow.
It sound like the touch wiz functionality Is useful so I would like to keep that.
So what are my options and is there a step by step guide to do this for newbies?
Thanks in advance.
Sent from my SM-G900F using Tapatalk

With the restarting issue try airplane mode on/off instead and see if that fixes it.
I'm also with EE on my S5 and as it is there is no Marshmallow Touchwiz for the S5 (apart from the one that'll be built probably tomorrow by the devs on here). You can use an S6 ported ROM themed like marshmallow however I have found they are fast at first but after long usage they seem to slow down a lot. You can get marshmallow via ROMs like CyanogenMod 13 which are crazy fast however that's based on stock Android and not TouchWiz. Rooting is a great idea as you can do just that (rid of all the EE branded stuff like Lookout, Amazon Appstore etc.) and also it doesn't require installing custom ROMs (however awesome custom ROMs are). Or you could install a debloated ROM (Generally makes your phone faster, declutters it).
Right now i'm running on stock 5.0 rooted until a stable 6.0.1 ROM is built, then I'll flash it to check it out.
Hope this helps
Edit: Also buddy you might want to have posted this in the Q/A section for future reference

Shaolin thanks for the reply.
The aeroplane mode on off works which is a bit less of a pita thanks.
Did you not find the cyanogen mod stable or did it slow down?
Any idea when a stable 6.01 will be released?
Any idea when 6.01 with touch wiz will be available?
Maybe it is better for me to wait for one of these also I'm concerned with 6.01 the sd card is integrated which is brilliant but sounds like it is difficult or impossible to get data off the card if I change the rom?
Sent from my SM-G900F using Tapatalk

CyanogenMod is very stable however the cons for me are the lower camera quality (due to the fact it uses the Stock android api) and also the missing cool touchwiz features like air view and gestures
I'm running a 6.0.1 touchwiz build right now but it is harder to install than standard ROM due to the fact you must use ADB to replace your bootloader/system etc.
The 6.0.1 official update will probably start dripping out at the end of the month or its predicted for April think
In my opinion, just wait for the official 6.0.1 touchwiz build because this build I'm running now is the smoothest I've ever had my S5 (so it will probably be even better in official build)
Let me know if you'd like a link the to thread for 6.0.1 touchwiz for S5. If you do wanna install it early then I must urge you BE CAREFUL! Backup everything

Custom ROMs... Are they still worth it?

I have been a flashaholic for some time, probably the Eclair days, but I really question if it's worth it now days.
Most Lollipop and newer ROMs, except for Nexus devices, seem to have some kind of issues... If not immediately, then over time. While at the same time factory ROMs get better, partially because the base code is better and because many manufacturers are getting better at it.
And now, some features are being blocked just by unlocking of bootloader, even if you're otherwise stock, like Android Pay and others like Pok�©mon Go.
I find all I really do now on custom roms is some interface tweaks... Change the battery icon, add a clear all button to recents, and add arrows to the navigation bar, all minor stuff. Otherwise things like Nova Launcher, SwiftKey, and GSAM largely don't even require root anymore much less a custom ROM. Part of it used to be for battery life, but now, at least on modern Moto devices, most custom roms struggle just to match the battery life of stock.
I've tried every rom for this device I can find, here and other places, and they all seem to have a variety of things that fail, from minor annoyances to major services broken like GPS, or they fail over time.
My question for discussion is it still worth it, and why do you ROM or even root anymore?

I used to run a variety CM ROM's on Samsung Galaxy & Note devices. Starting with the Galaxy S2 Skyrocket and then every decent device Samsung released until the bootloaders stopped getting cracked.
There was always something that just didn't work right and I'd have random crashes.
But for me it was semi-worth it. I like to tinker and customize a lot.
Fast forward to the last thirteen months with my first non-Samsung since. A Motorola Moto X Pure.
Best damn phone I've ever had.
And there is CM available, but I quickly discovered AOSP ROM's like Dirty Unicorn and Broken OS.
Both these ROM's are FULL of customization not found in Xposed modules, and both ROM's have been 100% reliable.
I may have had one lockup in the last 13 months. And everything from GPS to Bluetooth, etc. have all worked perfectly.
So for me, yes... custom ROM's are more than worth it once you find the right ROM. My phone is heavily customized to my needs and super reliable.
The only thing lacking with MotoX was kernel development. Which I guess is where you start losing some reliability.
But it's also where I'm hoping the Pixel will get some good development and I'm looking forward to it. :good:

Non-rooted stock MM has been going great for me lately. Lots of great built in features like Moto actions, etc. I play Pokemon while walking on my breaks at work, and the last few updates forced my hand to go back to stock. I was (am) also a flashoholic, and it was mainly to have custom features and better performance on outdated and mfg abandoned phones. It was also a must for my Kindle Fire. I really don't see myself going away from stock MM (soon to be Nougat) on my MXPE at this point. I still flash ROMs on my G2 and Note 3 though, but barely use them outside the house.

Hmm... I have been on that "rom that shan't be named on XDA" for a while now. After a month started suffering SoD randomly and Play Services has stopped issues. DU 10.6 couldn't maintain GPS lock, but 10.5 was fine, seemed to effect only a handful of devices, lucky me.
Anyway, thanks for your input.

I also have been a avid user of the "rom that shan't be named on XDA" for many months now with no real issues. By chance have you tried a fresh install again. The latest release was back in late August a 4.9.1 version that made corrections to some issues on the 4.9 release.

If anything try a fresh install and see if your issues were only from maybe a bad original install. If they show up again then I would say they are isolated to your device.

I'm out of town for the weekend, in a rather rural area, so maybe will try tomorrow evening.

LMT pie, adaway, naptime, and general tweaking are the only reasons I root on a phone this close to stock android.
I didn't run custom ROMs on this phone until about August of this year. That was when battery life on aicp started to get comparable with stock for me. I can get most of the features I want from gravitybox, but I prefer them baked into the ROM. Xposed always seems a little problematic even when you don't install janky modules. I really like the notification led; missed that when I got this phone. I know we're supposed to use moto display, but I think that makes more sense on amoled than a great big LCD. Never had good luck with lightflow or the led enabler apps, but the custom roms work great. I really like slim recents too. I haven't found any modules that work to put KitKat like recents on M ROMs.

TruPureXMM + GravityBox
Loved my MXP so much I bought one for my mom who was hating her iPhone5. Kept it stock (for obvious reasons), so I have a good baseline to compare to my MXP running TruPureXMM + GravityBox. I've tried a bunch of ROMS for this phone but I always come back to TruPureXMM + GravityBox. Oh, and Tasker.
There is no way in hell I would go back to stock.

I used Cyanogenmod on my HTC Incredible and Verizon Galaxy Nexus. Didn't root or ROM for a while due to using the stock ROM on the 2nd generation Verizon Moto X 2014 and stock Android on the Nexus 5X and 6P. But, I had the itch to unlock the bootloader on my Moto X Pure, due to curiousity, and because it's likely that we will only see one more Nougat update. I tried CM13, but I was getting UI freeze ups and slowdowns on multiple builds, so I tried Dirty Unicorns 10.6, and that has been working fine. I may return to the stock ROM after the Nougat update, but in the meantime, I'm happy experimenting with different ROMs on the Pure.

I'd be cool with stock- as long as I could debloat it.
And it was updated fairly quickly.

Stock for this phone is great. Better than most. Only issue really is Moto is so far behind on security updates. They are on what, May I believe? CM13 is Oct.

Stock here, never a issue. With Nougat in the horizon, a custom ROM is a big NO for me.

I would say TruPureX with a few mods is a very solid and stable way to go. I myself am on TurboROM which has ceased current development, but have ZERO issues. AICP's MM build is the most feature filled and works flawlessly aside from one issue I don't have on other ROMs, where my bank app only shows black when using the camera to deposit checks, making AICP unusable for me, but highly recommended for others to try as that's the absolute only issue I could find after a week full of testing (Kind of what I do as a hobby is push ROMs to their limits to find the issues.)
So in short: TruPureXMM, TurboROM, AICP - are all great choices without the negatives associated with many custom ROMs.

Pretty sure we are all here to push the ROMs to he limits lol?

Speaking of custom ROMs, I just searched android file host for Clark and there are new 7.0 builds of zephyros, pure nexus, aosp, and cos.
I'm in a limited data area so I haven't downloaded or tried them out yet.

Running the latest Zephyr after trying AICP and CM14. Uses substratum and SuperSU. Camera recording isn't working with snapdragon camera (FC), google camera (records but doesn't save). Had an android.phone FC but replaced with google phone/contacts and no problems so far. Still need to test speakerphone and bluetooth, but assuming those work as well as 6.0.1 I'm pretty impressed by Birdman.

Any roms that anyone can recommend? CM13 and OrionOS both have very bad stuttering after some time of use. Has anyone tried Pure Nexus or Slim6? Just need a good daily driver that can handle games without heating up so hot, and handle most social apps great...

Best s7 stock based rom

Hi guys I am new with this devices.
I want know what are your opinion about what are the best stock based costum rom for s7 flat for battery and performance. Sorry if my English isn't very good. Thanks in advice.
Inviato dal mio SM-G930F utilizzando Tapatalk

It's very hard to determine "best rom" everyone have their own taste / preference. In my opinion (ROMS which I tested) Helios ROM if you want minimalism stability and samsung features (like My KNOX and Secure Folder) work with root. SuperMan ROM if You want many advanced features and customization mods.
Hope this helps

Yes Im agree with you but I was thinking thet create a thread for confront our varius opinion, it may be helpful. ?Anyway, I have tested helios and I I found it little bit slow. Now im using the stock rom by ambasadii, but the drain for me is very hight.maybe I will try superman Rom. How is the battery drain in Superman rom and is better superman or superstock for you?

SuperMan and SuperStock is basically the same. SuperMan has much more customization features added. About battery drain I got around 5-6 hours screen on time (sometimes I had standby drain up to 10% overnight) but that was on Marshmallow I didn't have enough free time to test nougat as I need usable device at work. I'll try new SuperMan version this weekend. I think SuperMan ROM is best choice it is smooth, fast, battery friendly, fast updates and very active community.

Great! Thanks bro. Is only few time that I use this Galaxy. First I had a bullhead (nexus 5x) and this is my first Samsung so I don't know a lot the various rom for this device. After A bit of test I te I will tell you my considerations ?
Inviato dal mio SM-G930F utilizzando Tapatalk

As always is said, each device is a different world, in my case the rom of ambasadii goes very well I get up to 7 hours of screen with the AOD deactivated and in battery saving mode (And without energy saving mode and with the activated AOD I arrive to 6 hours calmly), with superman rom otherwise the battery is discharged a lot Faster but I have not tried its latest version.
PD: I always return to rom of ambasadii.

Hi, I found this Post and I would also like to ask now that it is 2019 (seems S7 will only be getting security patches from now on and no more Pie), Is Superman ROM is still the best stable Stock Based ROM? Or are there newer ROMs you would suggest. I'm a newbie to this though I have experienced rooting on other devices before.
I'm planning to Flash my S7 (SM-G930FD) and someone advised me to Root First then proceed to Stock-based ROM before going to AOSP-based ROMs. I feel like skipping to Stock-based ROM.
My Search leads me to the Following ROMS:
LightROM
The Galaxy Project
Superman ROM, seems like this thread support is closed, EOL.
Superstock ROM, Thread Closed too.
Can you also answer some of my worries below:
Mainly I want to use Tincore to Simulate touch input in games, will a Stock-based ROM deliver properly?
I have a Gear IconX 2018 (Samsung's BT Headset), will it pair properly and be useful in calls? (I've read BT problems with AOSP but haven't checked with stock-based ROMs)
Will Screen mirroring (Smart View) still work? (I have Samsung Smart TV at home, which I use to show my mother my taken photos)
Will the Camera have Problems too (same with AOSP-based ROMS)
What's OTA? (it seems direct updating of Custom OS from Settings Menu?
What's Dirty Flashing?

I can try to answer some, some are rom specific.
The BT headset should pair fine- it's stock based.
Screen mirroring should work if the rom supports it, don't use it so I can't say for sure, but I think lightrom has it.
The camera will have no problems at all, same as the stock rom. Gcam and other camera mods via magisk work as well such as 4k60.
OTA's are over the air updates so that manufacturers can give out updates wirelessly- stock-based roms do not support this and you have to flash new versions manually.
Dirty flashing is flashing a rom without wiping data etc., it isn't recommended as it can introduce issues, check with the rom and developer to see if they recommend it or not. Devbase is usually fine with dirty flashing updates.
Personally, I don't see the need for rooting or flashing anymore unless you need extra features or android pie, reduces the resale value as Knox is tripped and loses Knox functionality such as Samsung pay.

Can you also give me a list of most stable ROMs for S7 Flat (SM-G930FD), if I'm not troubling you a lot?
I still feel like flashing my device for learning purposes too. Anyway, I don't think I'll be using Samsung Pay and my Warranty period is also over, so I guess I have no issue with the knox thinggy.
