[Q]S2 kernels and rom's to S2 Plus - Galaxy S II Q&A, Help & Troubleshooting

Hello. I have S2 Plus and i wonder can i flash kernels and roms from S2 to S2 Plus? Becouse i feel the phone laggy and slow.

Not unless you want to break your phone, no. Only flash firmware specifically for your device unless you want a very unhappy ending.

CPU and GPU differs.DO NOT TRY!

lol thank you : Then i think buying a S2+ was a mistake.. Thread can be locked.

Yes it was, use the device as what it is, a smartphone.
Sent from the little guy

S2+ is a good smartphone, but has far less support here on XDA.
Main things however have been developed (root, recovery, roms) and also some kernel (such as bnl).
Maybe could try to exchange with an "old" S2...

[Q] optimized Kernels

Hi, Everbody
First of all excuse me for my bad English. I was a Galaxy s user until my phone was stolen. I am thinking of buying a Atrix, but before i do this i would love to know some things.
On my galaxy s it was very easy to make modification by flash en that kind of stuff. I want to know if this will be available for the artix to ? Manly i want to know if KERNEL modification is possible for faster, compatible, stable, and good battery life. On my galaxys these kernel modification really made a lot of differences. Other points are :
Improving the display or video and sound quality by modification of kernels.
Universal lagfixes Like changing the file system or something like this.
Brightness tweaks
Adjusted kernel HZ value to increase smoothness.
On atrix, the bootloader hasnt been hacked into yet but it is in progress so no kernels as of now. The problems suchs as lag fix and HZ values I feel are not neccesary on this device but I am sure we will see custom kernels soon enough
Thank you very much. I dont remember anything about bootloader with the galaxy s. Must be the downlaod mode in wich you can flash kernels in to the phone ?
Motorola has locked the bootloader on this device(and many others) so right now custom kernels are not possible and nobody knows when...if ever.
If you want kernels I would not hold out on the Atrix, it has an encrypted bootloader. This will be very hard to hack, but if anyone could do it it's the devs on XDA. If you want something on ATT that will give you lots of development options go for the inspire or buy another captivate. I bought the inspire and i like it alot. But you don't get the dual core and some other features that the atrix has. I guess you gotta just know what you want, either development or better specs. For me I will always go for the development.
I love development , but i also like the atrix. I get the feeling that motorola is not so development friendly. I'll wait a little longer maybe somebody can change this development problem.

[Q] difference between SII 9100 and SII 9100G

HI
i;m will to by SII galaxy , but i found 2 models in the market 9100 and 9100G , i found only the difference in the chipset and the GUP only , i need to know which one in better and the newest one ? and i read that you are not allowed to install custom rom on 9100G is that right ? and please if there are any other difference between these 2 models tell me ..
Definitely get an I9100.
Has a better processor, capable of faster data speeds if your network supports them due to the better processor. Lots more options on here/elsewhere so far as custom roms/kernels are concerned.
Do a Google search for the exact differences/specs.
You can install custom roms on I9100G, there just doesn't seem to be a lot of them around. That's certainly the case on here, put it that way.
i found a comparison here between the 2 models , like i said in my previous post all the difference i found in 3G speed, chipset and GPU , nothing else... so do you think regarding the previous differences the 9100 is better? by the way is 9100 is newest than 9100G ?
For me, the I9100 is better because there's far more custom roms & kernels for it on here (about a 20:1 ratio). Technically speaking by way of an "inferior" processor, the I9100G wouldn't even be on my radar. We have networks in Australia capable of much faster than 7.2mpbs.
If something is superior processor/GPU-wise, newest has nothing to do with it

As far as i understood from your reply that 9100 is better from custom ROM and kernels perspective but 9100G is better from specification perspective.. Right ?
No. Wrong.
I9100/T has a better processor/GPU and a billion times more custom/rom kernel options.

when i was googling i found this nice comparison
That's a good article so far as the specs go, there's a bit of opinion in there tho (the mention of the heat issue with the SGS2, never had these problems running stock & have rarely encountered them running custom roms/kernels).
At the end of the day if having choices so far as different custom roms/kernels are important to you, then you'd probably get a I9100/T. If not, you'd get any other I9100 you like.
With the SGS3 due later this year, the lack of custom firmware available for the I9100G is very unlikely to change, as well as most of the developers living in countries where the I9100/T is the most commonly/readily available device and those devices having seemingly larger userbases (at least on here anyways).
It's entirely up to you.
G = very very BIG no 99% of users regret buying the G model .
But your choice .
jje
here is also another useful comparison see the last paragraph "Which phone to buy?"
OK. So you should have enough info to make an informed choice then.
after a lot of searching and according to my requirements i think 9100 will be suitable for my needs.. Thanks guys for your help..
Definitely the GT-I9100 !!
If you are interested in modding, playing and getting support for ANY phone, NEVER EVER go with models that have been branched-off from initial model. They just cause trouble regarding updating, developer support, and OEM support. They're a cheap sales trick, used by companies (Samsung) who are more interested in selling NEW phones without any long term commitment to support like Apple's 3+ years.
Just look at what happened to the I9000! It is still my opinion the best phone ever created by Samsung, but they already stopped supporting it long time ago, including by Google Android ICS, even though there is no apparent reason for not having that support...

That's not entirely true. Yeah the S1 may not be getting ICS, but support has not stopped.
On the S1 forum the latest firmware is a leaked JVU 2.3.6, same version as the latest S2 firmware. It also has plenty of new changes, including the Note lockscreen & faceunlock

Sent from my GT-I9100T
hi,
so after reading about the differences between the two models i feel kinda screwed. after my i9100 got wet i got some cash from the insurance company and went to buy a replacement.
good thing i'm a newb and didn't think about the possibility of a cheap rip-off version of my phone existing. so i just got a new "sgs2". well great. aside from more than lacking custom dev support it's also supposed to be slower and weaker in regards of game performance.
do you guys think, this will improve or should i throw my phone into the sh*tter and try to get another replacement? if they even had any non-g models. i feel cheated! thinking that for only 50€ more i could have gotten a nexus at the same store.
/edit: i do not acutally plan to heavily mod my phone. just use bacis (root) apps and all that. no custom rom or anything. i only fear that updating to non-official android os versions in the future (like when the sgs2 is outdated in ~2 years) might prove difficult. if i can't get ics on this phone i'm going to murder everyone at that store.
My first SGS2 was i9100 but it crashed and seller gave me my money back. So I ordered the same phone from another seller and he sent me i9100G but on his site was clearly said he is selling i9100 with MALI400 GPU.
So I sent it back again and I am waiting for answer from seller now.
Here is my comparison i9100G to i9100 version:
- i9100G was slower in rendering web sites in Chrome and opera
- same battery time
- G was slower in apps
- I had problems with many apps on the G version, they were crashing all the time: opera, email, games...
I didn't like the i9100G at all, it was slower, less powerful phone with crashing apps for the same price.

i9100g vs i9100 roms

Hi i'm new to this device, sorry if this has been asked before.
I noticed for CM10.1, the i9100G variant has RC4 for it, compared with only nightlies for the i9100.
Does this mean there's better dev support for the i9100G model? But the i9100G sub-forum seems smaller?
I want to buy the one that had better dev support & custom roms run better on, so please advise, thanks.

9100G has a TI-OMAP chipset and all sources are out.The 9100 has Exynos and not all the sources are out.But overall the 9100 has slightly better specs.Well, for custom roms as CM the G version is better.
It's not the support that's missing but the sources.But it's also true that the last nightlies for 9100 are absolutely stable.There are just few games that are not working well.

So the custom roms for the G are more stable? Does camera well work on both versions?
The I9100 (still) has much more dev support than the I9100G and always has. This talk about sources has nothing to do with anything.
Having said that, given the phone was released two years ago, I wouldn't be buying one now. I'd be buying an S3 (which also has a lot of development) or even an S4.

The camera is working well on both.But you just cannot tell, that custom roms on G are more stable.Custom roms are not just a phone thing but also developer's and 9100 has much more dev support.I gave you an answer based on your question about CM. I have a 9100 version and I wouldn't change it for a G.Few non working games on CM and CM based roms are just not enough for me.The Mali GPU is much better for me as the Power on G.And imho the G version was made by Samsung just to reduce the production costs.

Sources has nothing to do with anything? Tell it then to "codeworkx".
Codeworkx has a bee in his arse over Samsung not releasing sources & enjoys the attention he gets when he regularly cracks the ****s over same. Every other dev sucks it up & produces the best rom/kernel/whatever they possibly can in spite of same.
The I9100 is the 'superior' device in every possible way (hardware, sheer variety/volume of both past & present development). If you're going to buy a two year old phone, you don't buy the I9100G unless it's either given to you for free or it's a helluva lot cheaper than the I9100 (And I mean a lot cheaper; even then I wouldn't).
I'm waiting for the nexus 5, but want something a little faster in the meantime...
Just got offered a GS2 i9100 variant for $150 (USD) great condition, should i accept it, then sell it when the N5 comes out? I wouldn't make too much of a loss i think, the value might be down $50 at most after 6mths?
Oh and gaming isn't important to me....

Should i buy the S2?

Hi guys. I know the S2 is one old phone, but i found one, slightly used for just over 110 dollars. I want it mostly for messing with it and putting kitkat on it (since he hates Samsungs bloat), but I intend on giving it to my father to replace his Galaxy Ace 2 which is stock, untouched.
Is it worth it?
No.

Get moto g instead
Sent from my Nexus 4 using Tapatalk
i am using it its one of the best phone around moto g is good but newly launched s2 is old and has good support from devs
It's really old, mate. Most of the dedicated S2 devs have moved on. We do have good ROMs but most are made for a variety of devices including S2 (CM, SlimRom, Omny).
Also, the S2 hardware is no match to current gen chipsets are way better. Faster GPS, better WiFi connectivity and IPS-LCD tip the scale for me....
I'd go for a current gen device with modest specs. Sony have good simple devices, MotoG is a good choice. The Nexus4 comes to mind too.

Have my words.... No ...
Reason - 1.most of the developers have moved on .
2.Although we have kitkat.. Its still no where near to what real kitkat is...
Fanboys will try to prove me wrong but i have seen kitkat on moto g and s2 ... And belive me u cant compare how bad kitkat we have (no disrespect here ) all thanks to sammy...
3.Official cm support for kitkat came very late .. Very late i mean very late... Probably we wont see official cm support for next version of android...
If it wasnt for wayland_ace ...we would have no kitkat yet .
4. KITKAT still has lots of minor bugs.
5. Eek i run stock rooted deoxed ics and its the best stock rom combo for fast performance and xtreme battery life... Only for this benefit.. A YES is present

[Q] Samsung S2 Variants.... what one?

Hi,
I'm going to be buying a Samsung S2 for a family member as a backup phone but want to put CynanogenMod on it and change the pit size... but the variants of S2 are confusing, the family member currently has a Samsung S2 9100G and has http://forum.xda-developers.com/galaxy-s2/development-derivatives/rom-cyanogenmod-12-t2955551 installed.
I have the option of buying a cheap working phone from someone I know but it is an 9100 model, one of their original batch, is this compatible with the ROM and pit files from above?
Or should I pass on buying it and instead get an 9100G? What other ones are ok and obviously work in the UK?

I would go with the international version(i9100). It is more common, and there is more development for it. The "G" version has a different chipset, which makes it incompatible with roms from the i9100. From what I've heard the TI chip isn't as good overall as the exynos chip in performance either, although the numbers are the same(1.2ghz)

Which is going against what I read kind off... According to wikipedia:
Galaxy S II - Model GT-I9100G
The Samsung Galaxy S II GT-I9100G was released in late 2011, and is usually sold instead of the original GT-I9100 in certain markets (mostly Asia and some parts of Europe). An overview of the Samsung Galaxy S II GT-I9100G can be seen on Samsung's official website.[61] It features a Texas Instruments OMAP4430 SoC instead of the Exynos 4210 in the GT-I9100. It is visually identical to the GT-I9100, as well as having the same 1.2 GHz processor speed and dual-core ARM Cortex A9 processor technology. However, the SoC is of a different design and the Mali-400 GPU has been replaced by a PowerVR SGX 540 GPU. This difference in the SoC makes this variant incompatible with custom ROMs intended for the I9100, but it has been steadily gaining its own aftermarket support (such as from CyanogenMod[62]) due to the relative ease of development and the openness of the TI OMAP platform..

More common worldwide, meaning it has more developers and variety of roms etc. Perhaps where you are the "G" is more common as it was only introduced into a limited market.
The difference in hardware is negligable though, I only meant to say they are incompatible between them. The TI is indeed open source, so if you want to develop your own rom/kernels and create your own device tree/kernel tree etc. it would be much easier from a purely aosp base.
I guess at the end of the day, if you just want to install a rom, then forget it, either one will do. And the fact you have the files already for the "G" it might be easier to get another. If you plan to update the rom in the future or try a few different ones to see which one you prefer, I would recommend the i9100

I have no idea!! I don't have a i9100g, but everthing I've read indicates it is not possible. Can you take a couple of screenshots in "About phone" in settings with rom build and device variant? The only thing I can think of is if they used the same chipset as i9100 for some of the i9100g's at some point?? I don't know

I checked one and it was the i9100, I swear the other is an i9100G though, if it isn't then I'm seeing things and got incredibly lucky flashing that ROM lol, silly me.
