Does anyone know if the EVO 4g's processor can be swapped out with an aftermarket dual core processor like the one in the 3D. If so will it break other parts in the phone. Just a thought.

dont think it will just be easy as that i think we will need a modified rom and kernel that can work with the processor and some other stuff if it were that easy i think most people would do that
Thanks just a thought.

If it were only this easy. But my buddy Afteraffekt has some reasons why this would never work.
Chipsets arent comaptible
CPU is soldered on
RAM isn't compatible
Just physically doing the swap is nearly prohibitive. With surface mounted chips like this, you can't just grab a soldering iron from Radio Shack and have at it. You need special equipment, and I don't even know if HTC themselves would remove processors and replace them (i.e., for servicing). They probably just pitch the board. Add to that the fact that the chip size probably isn't the same, so it wouldn't match up with the leads from the old processor, and even if it did, the pin-outs might be different.
Finally, even if you could make it physically work, other parts on the board may not be designed to work with it, and you'd probably need to put together a custom kernel at least to get the thing to boot.
So....short answer...no.

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

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.

Lol, total brain fart there. Thanks!
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?

Thanks, guess I'll get to porting. I just thought that it might be possible because you can use samsung fasicanate roms on the samsung mesmerize.

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.
Hello all
I just bought a out-of-factory conditioned Desire Z on flea market. I had this phenomenal phone 6-7 years ago, and I bought it for 3 euros now
I fell in love again, this device is a lesson to all these new designers what a build quality and designer solutions are.
Reading couple of threads here, I figured, Desire Z became unusable. One can eventually use it for phone calls and SMS.
Seeing that the biggest problem is lack of RAM memory and possibility of upgrading to newer versions of android, couple of things came to mind:
Could it be possible to replace RAM chip ? I know from experience that many board manufacturers make RAM memory on top/underneath CPU chip, but if that is not the case, would it be possible to solder the same BGA layout chip with higher memory ?
Also, a wild idea, but would it be possible to install a board from a newer phone ? Form factor surely is a problem, but for example, LG G2 motherboard is really small, maybe some other motherboard could actually be fit in Desire Z ? If that would be somehow possible, all that remains are few tweaks on the system to make keyboard work.
Has anyone else thought about this, and maybe took it further than just an idea ?
Hello there,
I was wondering if there could be a chance that I could swap ram chips between my S9 and the Note 9.
They have both the same SoC but with different ram chips on the very top of the SoC, I know you can physically swap the ram chips but I was worried if the Stock software could boot the phone without any changes made to it. I was also considering a full SoC swap, maybe that could increase the success rate of the SoC not dying.
Thanks in advance
short answer no. Long answer will be posted soon

Not that I know of. That's why I'm asking. Of this was possible it would open up some DIY ram upgrades for a lot of phones if it works.
I've seen similar things before, with the old Sony UX UMPC, they figured out to solder another 1GB or RAM on top of the existing 1GB RAM

Nice, it's basically the same thing on the S9 in theory. You de-solder the SoC from the original phone, you get the SoC (the same SoC with different Ram capacity)that you want from an other phone and then you solder it on the original phone. I was wondering if there was a software compatibility issue. You could de-solder the Dram chip that is located on top of the SoC but I think that's a little bit more complicated. I have never done this, I've only seen photos of the motherboard of the S9 and how it's made.
