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

No, it doesn't. That site is also wrong about FM radio (it doesn't have one) and gyroscope sensor (it does have one).

That whole comparison is kinda strange. They really ding the Nitro for slower download and upload speeds, but both the Nitro and Skyrocket use the same Qualcomm SoC, which includes the cellular radio. They should be almost exactly the same if tested at the same time, on the same network, connected to the same tower. I think whatever testing was done wasn't exactly scientific. The battery life was a odd too, it looks like they took the time straight from LG (probably underestimated) and Samsung (probably overestimated) specifications directly. They also give the edge in display to the Skyrocket, even with its much lower resolution and PPI.
Anyways, on the original topic, the Nitro might have an FM transmitter. Someone asked about the P903s FM radio on Ricardo Cerqueira's Google+...
Hem Acharya - Thanks a lot. Just a quick query. By any chance is p930 going to have fm radio functionality discovered and enabled?
Ricardo Cerqueira - No idea, and it's not a priority...
FWIW, CM9 doesn't currently support FM at all, and even in CM7 we don't have FM support for the bcm4330 chip the p930 has.

They're probably talking about FM radio reception and not transmission but either way, even if the hardware is there, there doesn't like any software support coming in the near future.
According to here: http://www.ubmtechinsights.com/google-nexus-7-teardown/ there is an
AzureWave AW-NH665 chip which is endowed with an FM radio tuner. It would be really awesome if some talented soul could develop an app for that!

It depends on whether or not the bcm4330 chip actually sends power to that module. I haven't seen that module fire up in dmesg. That could mean that we simply need a driver for it. The fm framework is already out there. I'm not really a hardware guy but just some thoughts.

On another note, I have been playing with Samsung & HTC modules & drivers for the 4330 (Vivid & Captivate Glide) & I am getting 5Ghz wireless-n working sporadically. Just as HTC has added the capability to newer roms, it would also be possible for it to be supported quite easily by Asus as well. Would be great for streaming.
I would love to see this as I'm sure many would who wish to use the FM Radio for and N7 in a car install, I would gladly pay into double figures for this feature, any devs wishing to take it up there is a big market for getting fm radio working on the n7, do it and watch the £££ fly in ........
I doubt if a driver without an antenna would work - and I saw no sign of an FM antenna in the teardown.
5GHz support would be sweet... Antique adapters in the house really keep me speed limited on 2.4GHz (54MBS)..
That really sucks about the antenna. sometimes I like to listen to the football games out in the yard. Guess I'll have to use my phone.

I think perhaps the most definitive answer to this would be from Mike Reed, who I believe has a Nexus 7 and is also the author of the Spirit FM app. In this post it looks like he thinks it'll never happen.
Too bad... I use the FM Tuner in my phone all the time as well.
I just use Tunein Radio Pro. Was a FAOTD on Amazon. Used the free version before that. Gets the local stations I like...

Exactly. We got a hurricane bearing down on us right now. The last time this happened, We were without power for 3 weeks, and 3g was a laughable dream because all the cell towers were down. We NEED FM radio.

Your Nexus battery isn't going to last 3 days. If this is for disaster situations, just get a regular FM radio or one of the ones where you can power it with a hand crank. Either way we don't NEED to have FM on the N7. It would just be a nice perk.

Most mobile devices utilize a headset as the antenna. I wonder if this could be as simple as porting a FM tuner app from a device that has the same chip set with working FM tuner app?
Sent from my Nexus 7 using Tapatalk 2
I was wondering if anyone had any success? I was thinking about integrating a Nexus 7 as a car stereo replacement. Mount it in the dash (trimmed to make my GM Double DIN space a little wider), and route a line out into an EQ, which then would feed into a couple amps. ~$50 for a used 7-11 band EQ, ~$200 for the Nexus = a pretty kick butt deck if you don't need CD. But I would still like FM for traffic, news, games, radio contests, etc....
Last time I checked there need not be an internal FM antenna, most devices with tuners in them actually use the ground lead of your headphones. This is also why radio apps often fail without headphones or powered speakers attached.

Lol, are you serious? I don't know about you but I had my N7 under clocked at 900mHz with WiFi on, bluetooth off, and display all the way down, and I got a week on my battery. A Nexus 7 is a tank when it comes to battery you could EASILY get 3 days off a N7 battery.
You can have FM on your Nexus 7 now
Just get one of those cheapy RTL2832U based USB DVB-T dongles (they can be as low as £5.60 from eBay - http://www.ebay.co.uk/sch/i.html?LH_BIN=1&_fcid=3&_sacat=0&_from=R40&_clu=2&_nkw=RTL2832U&_sop=2)
Then download SDR Touch - https://play.google.com/store/apps/details?id=marto.androsdr
You don't even need to root your Nexus 7.
You might want to have a powered USB OTG cable in order to make it last for longer, since the tuner and the SDR decoding on the CPU is quite a battery eater. Another downside is that you can't charge your tablet while having something plugged in the USB port.
FM Stereo and even possibly RDS are features that will appear in SDR Touch soon enough
An added bonus is that you can now also listen to police frequencies or analogue TV sound while you drive as well

Tried that, not working, maybe because i do not have powered usb hub. But does anyone know what is the problem when device freezes and restarts whan plugging out otg?
Go for spirit radio on google play.....
I have read that gnex has hardware that supports Bluetooth 4.0, is there a rom or kernel that has enabled it to work or is it even possible?

Thanks. The reason I ask is that I saw this on Wikipedia. It states that it is Bluetooth 4.0 hardware compatible. 2nd reason is I bought those Bluetooth speakers with Bluetooth 4 and apt-x support. I just want to maximize it to it's full potential.

Wait wait wait, one moment, i don't understand. The hardware inside GNeX is bt4 but it has driver that doesn't support that but only bt3, is this what are you saying? It sound really strange to me, maybe that statement on wiki means that GNeX can use other hardware with bt4 even if it's bt3 but not at full power, am i wrong?

It'll be clearer if you check out the link in my previous post. Gnex contains a Samsung SWB-B42 BT 4.0 Dual Band Wlan FM Tx/Rx chip so the hardware is there. The thing is the driver that is currently installed on our gnex only has BT3 coded in. And even if the driver utilizes the phone's BT4.0 capabilities, Android in itself doesn't have native APIs to allow developers to take advantage of the new features.
Sorry if i didn't read the whole link but i was at work so, you can understand... Thank you for the very clear explanation, however it's really really strange this behaviour by google...
Will Google/Android ever get BT4/BLE working on the GNex? Or shall we move on to another device if we need/want it?
I have been searching for a teardown of DEB but cannot seem to find one. Does anyone know the differences in the hardware between FLO and DEB besides the obvious, one has a sim card and one doesnt.
Is the LTE capability integrated into the SoC on DEB but not FLO? If not, is the LTE chip located on the main board with the SoC or is it on the daughter board at the bottom of the tablet where the sim-card plugs in? Any help is appreciated.

It's my understanding that Deb is relatively the same as Flo with the exception of data and full GPS capabilities. Many have flashed Flo ROM's on Deb devices and they will work but will not have data and full GPS capabilities, which defeats the purpose of having a Deb. An actual Deb teardown I have not done though.

I don't remember seeing it anywhere, but can I flash Deb roms on my flo? Theoretically, it should be fully functional (the flo, that is...), but I haven't had the guts to try as yet.

I don't actually care to try...I was just curious. Curiosity isn't enough of a reason for me to run that risk.
I've flashed deb roms onto my flo in the course of doing testing: yes it will flash and boot fine.
I forget if it would work without bugs (testing mainly consisted of making sure it boots and nothing major is broken, like wifi, screen, or touch)
Obviously you wont magically get cellular support, it'll be like how it already is: the rom will simply see a radio that cannot connect/sense any type of network.
The biggest hardware difference is obviously the lack of the modem, it's an external module like on all S600 devices.
Software wise there isnt that much major differences:
They use the same bootloader
They use the same kernels
At launch they had the same basebands (flo's never gets updated though info on wiki)
The actual drivers and roms are not identical though, at the very least they're built in both 'deb' and 'flo' configurations, at the very least they have different names inside the drivers

My experience is that some ROMs will work between the "Deb" and "Flo" models but others won't. Some are even advertised as being bisexual. :silly:
It's entirely possible for the hardware on both models to be exactly the same, with some deeply rooted firmware switch to activate LTE. I'd think from a manufacturing and inventory management point of view, it'd be cheaper to build one version due to less tooling and inventory holding costs.

Regardless of if the modem is in flo or not, there's no sim card tray on flos.
They could hypothetically use deb boards that otherwise work 100%, except somehow recieved a faulty modem chip,
but without a sim tray you wouldnt be able to do much with just that.
Many old tegra 2 based tablets had a PCI-E mini slot (PCI-E mini can do either PCI-E and/or usb, only the latter was actually available and that was what was used) where the modem went, you could likely solder in a slot on the wifi model and get the same modem elsewhere, but you'd need to also get a sim slot and tray to actually make it useful.
