Would it be super hard to port roms from the i9100? Doesnt it kinda have the same bands as the skyrocket ? What makes it different if its drastically different? JW?
I'm not a developer but this is how I understand it (I might be wrong though): It would be akin to trying to port a HTC or Motorola ROM to our phone, because the T989 has almost nothing in common with the i9000. They use different hardware, specifically the CPU and Modem/Radio on the SoC (Socket on a Chip), and therefore a different kernel which needs different drivers, etc. Skyrocket uses almost identical hardware, so a lot of the core files are the same.
yup! what Mitallust said
understood my friends thanks for the answer. I dont know if you guys have been in that forum but they have a rom Called sensation that looks badass. i wish someone could make something like it,
Socket on a chip made me lol.
My corrections in red.

Hi everybody!
Little question appeared in my head- have anybody heard of replacement of CPU in the g2 or other htc models? Is ot possible?

Anything is possible with enough tools and knowledge

well, i understand that.
but maybe somebody from xda tryed this?
Never heard of it actually attempted but the question has been posed before.
Are you asking about replacing it with the same SOC that came with the G2 or a different one?

i think a different one, as an idea of maximizing productivity
Afaik, it hasn't been attempted before. The problem is it's not like the socket-based cpu's in pc's. These are system on chip, meaning everything is on them; cpu, gpu, everything, as far as I understand it. In a pc, as you know, these are separate parts that can be readily changed. Plus, no one really knows if the other hardware would be compatible. Then after all that, you need to get the software to work. It's a hell of a job.

Well I think it would theoretically be possible to change the CPU if they are pin compatible, which happens often with CPUs from a same series.
BUT
Where would you buy a cpu? what do you think it would cost?
and how would you assemble it on the mainboard, those modern IC's have very small pins/balls underneath it, which you can't just solder!
I was thinking after reading this yesterday and posting. Since we would be dealing with a SOC the baseband radio would be integrated into it - which means *if* this could be accomplished, it would give us the freedom to literally use a phone on any carrier we wanted will full data access speeds i.e. use the G2 on AT&T '4G'.
Obviously the 'easiest' method would be to use the SOC out of a Desire Z since everything would be the same except for the radio - thus eliminating software issues. Now all we need is a way to deal with the extreme micro scale of all the pins and such.
Now to switch out to say, a Tegra 2 - I doubt the pins match and that goes for any dual core. To go to something like an 8xXX series (are those dual or single?), now that might be possible but as far as single cores go the G2 has IMO the best out there. Sure there are some slightly upgraded 7xXX series processors out there but nothing worth the headache this would bring.

Its absolutely identical in every way. The radio amplifiers are NOT in the SOC, so this would NOT change the frequency. In addition, wouldn't it be easier to just swap phones than to rip them both apart to trade identical components first?

The 8xxx series is identical. In fact, the 7230 ***IS AN*** 8255, its just **DOWNCLOCKED**. They changed the model id number ONLY.
An 8260 would DEFINITELY NOT be pin compatible, so the limit is 8255, which is pointless.
Well I agree it would be easier to just switch phones, albeit cheaper I was just answering his hypothetical question.
I always figured being a SOC the radio would be itegrated into that, guess that remote purpose for switching out the SOC is out the window.

As for doing it you would need a micro balling and reflowing station

Is it possible we will see these on our phones at all? I think it would be fun.
unless some1 develops a new rom with that, then no
i wouldnt expect any of them to be ported because there wont be a lot of demand for that since one of the points of nexus is to be vanilla android
There is definitely not going to be a lot of demand for this. People buy the Nexus often for the specific reason of not using TouchWiz, Sense, or Blur.
And its definitely not going to happen until these companies start releasing phones based on Android 4 with the skin attached. Even then, its a lot of porting for a very small # of people.

Of course it's possible, and the one way you can be certain it happens is to port it yourself.
You'll probably have better luck with TW to start with, and it would make it much, much easier if you can find a phone that is almost identical to the Galaxy Nexus to port from. eg. same CPU, most same hardware, etc. A lot of times you can get it booting by just swapping the kernel with a native one and making a few minor changes to the ROM.
I'm attempting to port the leaked ics sense to the g nex today. Going to take some work but there are a few files that I know need changing and I'll use imoseyons kernel.
I recently purchase a epic 4g, and to my surprise look on phonearena.com to compare it to the nexus S. I found this is what the have in common:
Same processor clocked at same speed
Same screen(epic 4g is slightly bigger)
Same cameras(front and back)
And everything else
Only difference:
Epic 4g's hard keyboard
My questions is, will nexus s roms also work on it, has anyone tried? Thanks

umadbro? In your theory too many HTC phones would have universal ROMs...
Frankly speaking, never. Differences lie in where you can't usually see, like touch panel controller chip, SD card support, baseband (Nexus S is strictly a GSM/HSPA phone, while E4G is CDMA/WiMAX), storage size and partition table, etc... No devices are the same or, say, near-identical enough to make ROMs universal (that is, with the exception of some "unbranded" phones that are shipped to different manufacturers just to make their shells, so hardware could be identical)
However, based on this similarity across all phones with S5PC110 CPU ("aries" board), ROM codes can be shared to a certain extent, and some ROMs can be easily ported from Nexus S 4G to E4G or vice versa.
Satisfied?

No, these are almost identical phones actually (look at the shape and model number). Mesmerize is just a re-carrier-branded Fascinate with (minor) baseband difference.
I haven't looked into the files etc. in the ROMs, but from looking at the physical hardware specifications they are VERY similar in terms of processor, GPU, RAM, internal storage etc. The question I have is whether they should be very easy to port from one device to the other? Are the drivers for the sAMOLED massively different from the LCD in the Tab Pro?
I may have a go flashing one of the Tab S 10.5 ROMs on to my Tab Pro 10.1 and see what happens...
Does anyone know if there is anything obvious which would prevent it from working? Other than the model ID checks obviously...

I wouldn't try flashing a ROM for a different device on your Tab Pro, you could get yourself into a lot of trouble and you could end up with a Bricked tablet!!!!!

???? Look again. The Pro uses a Snapdragon 800 SoC from Qualcomm, the S an Exynos SoC from Samsung.
BTW, there is a sticky in this forum indicating that questions belong in the Q&A/Troubleshooting section, not here. The mods will move it shortly.
Apologies for putting in the wrong section.
that aside, the tab pro 10.1 comes with the exynos chipset here in the UK. The 5420 to be precise, the exact same chipset that the tab s comes with. The only differences between the tab pro 10.1 and the tab s 10.5 is the SAMOLED and the S-pen compatible touch matrix.
I know there are variants of the tab pro with snapdragon chipsets, but the 10.1 is exynos.
FYI
Having had a bit of a mess around with some of the ROMs for the SM-T800 (Galaxy Tab S Exynos) I managed to get some pleasing results. Some elements don't work, mainly the keyboard and WiFi at the moment (presumably they use different wireless chipsets). Managed to fix the Wifi but still working on some other bits and pieces.
May contact a ROM dev who works on the Tab S and see if I can produce a port of one of their ROMs. Mainly interested to see if I can port over a Lollipop ROM but thought starting with a 4.4.2 one was a good shout.
In the most light-hearted of ways - SHUN THE NON-BELIEVER!
If everything works as planned i'll set up a ROM port in the general development section of the forum. :good:

Kudos to you. I have a 10.1 pro and the chipset is Exynos (I'm in UK). Interested in the port which is likely to be successful. I'm also interested in rooting it whilst keeping Knox 0x0.

Apologies people, not made much headway recently as work has been manic (I'm a 25 year old IT account manager so free time is a rarity!)
I am still awaiting a response as to whether I can kang some bits from other ROMs as well so will do some chasing and see where we can get
I have been running my mash-up for a little while and there's still lots to fix before it becomes useable...
I'm glad people are interested in this, though
One thing to one of the posters, this is just a 'flat UI' style ROM based on 4.4.2/4.4.4 so is NOT a full LP ROM - that may change, but I haven't played with kernels enough yet to try and lob LP on it properly.
:highfive:
Keep trying your best. We are waiting. Do let us know if we can help.

A questions for any Australians out there , or anyone else that has the answer.
I have seen a lot of posts about the USB-C versions (2.0 vs 3.1 etc), I have also asked Samsung Aus directly and they cannot provide me an answer......(not sure why). Maybe they cant until the phone is released.
But i would like to know what version the Australian model will have......2.0 or 3.1?
This is the model number that comes up on my order; SM-N930FZKAXSA

As far as I'm aware all the Galaxy Note 7's have USB-C 3.1
Actually, disregard that... I just had a look around, apparently it varies from one chipset to the next. I'm guessing the Qualcomm Snapdragon models may have 3.1 and Australian Exynos models 2.0, but not 100% sure.

See, i thought they were all the same until i started digging around as well. Now im confused.
It would be nice to think that being the latest unit it would have 3.1, but i guess it depends on the chip handling it......and in saying that, dont the Exynos chips run better than SD? Im not tech savvy with that so i could be completely wrong in my thought process.

They are both very close in performance, but in majority of videos comparing the Exynos & SD variants of the Galaxy S7 the Exynos comes out as the better performer, although I did see one video that the SD variant won, so not sure what was going on there. The bigger difference it seems is that Qualcomm releases always up to date source code which is needed to get all components of their platform working on AOSP, Samsung does not, so many people tend to like the SDs more for this reason. But in the US the bootloaders are locked down by the phone carriers so they can't modify the software on them anyway.
