It's a wild, stupid question but if I brought a screen for the Sensation XL, the processor from a Galaxy S II and the body (modified to be big enough) from a galaxy nexus how much work would be needed in to making this super phone?
Rip the other components from other phones.
I know that software and components would be problematic to say the least, but could it be done? Is it POSSIBLE?

GPU, correct power stuff, all that stuff. technically you could but it's a lot more than 3 words.
Possible: Yes.
Probable: NO.
Could be the new thing in phones! like in desktops.
It would be great though!
I'm guessing you'd need to build your own drivers and kernels and all that goodstuff. I think it is possible but itd be way to much work.

Android should have a universal kernel. That would be awesome.
Sent from my Wildfire S powered by .sense using my fingers.
Well, let's start from the beginning:
You need a SOC. I doubt you can find a SOC by itself, so you would have to take it from another phone. Another option is getting a mainboard from a device, and you can find spare mainboards.
Next, you need to do some research on how the display is connected, what parts you're going to use, if their way of connecting is supported by your mainboard, etc.
Then, you have to find a way to write something to that SOC. If you don't have a mainboard that's programmed, you'll need to make the partitions manually, which means you will need a programmer (not as in someone who can write code, but a device which can write stuff to NAND chips using JTAG or something like that) to write a NAND to that SOC's MTD.
And what you have to write to that NAND? You'll need a bootloader, so you could stick with a SOC from a HTC and use the default HBOOT, or I would prefer a clean bootloader. You could check the source code of cLK for HD2, which is a really decent bootloader.
Next up, you have to get hardware working. In other words, building a kernel. Get the Linux kernel, find all the parts for all of the hardware, and actually get it up and running. And I can tell you, this is a hell of a job. Compiling a kernel from source is easy, but implementing all of your hardware in a kernel is pretty difficult. You will have to get a barebone up and running, make it dump a log to somewhere in the RAM or NAND, read that dump out, check what it's saying, and you know where to continue. This will cost a LOT of time.
Once your kernel is running and it can echo something to the screen (which is already hard by itself), you have to build an Android image from source, which is not hard at all, and extract that image to a partition on the NAND. And then, set up the rootfs path in your kernel correctly so it knows where you put that filesystem of Android.
And then, boot it up, hope that logcat can tell you something, perhaps Android will boot, but the chance is pretty small that it will the first time you try. And when you finally get into Android, you have to get all the hardware working there again.
And then you have a working Android device, but I'm afraid you can't make this thing legal, as you need an IMEI, and as far as I know, extracting and messing with IMEI's (or ESN's as they're called in the USA I believe) is not allowed, so you do have to know something about all of that stuff to get a GSM radio up and running.
It's possible, but I suggest you start with replacing a display of an HD2 with a display from a Desire for example, try to get it working, continue replacing stuff, and you know if you're able to do this.
If you want it, you could get somewhere, but it will cost a lot of money (I think it'll cost about 600$), without knowing if it will do the trick.

Meh'
It's just words, there not going to be important in this instance.
If I were building a rocket then yes, words are important.
But I'm asking is it POSSIBLE to build a phone.
Possible... the simple way, get a working motherboard of s2 or gnote, get its display spec and wiring dia, get the display u need.. get its spec and wiring dia. Cross refer the two disp. If it match in some way, get it fixed to the board, build/get a body for the thing. Done.
Nearly impossible.. if any thing is not matching , and u fit it, well u gonna get a burned disp /board. And since u r doing some R&D, u will have to spent a lot, may be as much as for getting 2-3 top rated phones.

This is awful because of the licensing, test and certification requirements. Phones are only cheap because of economies of scale which you lose there. It isn't like a desktop where you can swap pieces easily. It is more akin to an even more ****ed laptop.

Microshaft doesn't exactly have a strong track record when it comes to security....
Unlike Linux, which Android *IS*.
That being said, rooting ANY Android device is *easy*. Just not necessarily through the conventional back doors.
If you can read and write the chips, you can very easily make any modifications you like into the root filesystem, which can include adding an 'su' command. Only problem with this is that it generally requires a hardware approach, which is beyond the scope of the average user... who probably shouldn't be messing with root anyways.
I do, however, feel a bit of a letdown in this issue though. The unfortunate thing is that the carriers still are trying to call the shots (and generally succeeding due to popular ignorance). I would like to see this change -- there was once a time when you bought your land phone from the phone company and this is not so any more. Right now, most people are still buying their mobile phone from the phone company, even though it isn't necessary. I would definitely like to see more dealers for non-carrier-specific cell phones, and to have them show up in popular places. I would like to see these sold at places like walmart and radio shack so that you can just walk in and buy a phone with no strings attached.
There are a few reasons why I opted for an ADP1...
1) no contract,
2) no controls,
3) no carrier,
I bought it outright, its mine, and I can do what I like with it. People who are interested in the freedom of an unrestricted device should opt for this approach. ADP1 is STILL AVAILABLE, and there is not much about the new devices that improves on it.. sure I admit that having a little more ram would be nice, but the keyboard sure makes up for it. Yes, the majority of devices can be converted into an unrestricted device, but it just isn't right that you would have to hack it.

Dude, vista was hacked before it was even released.
And fyi; hacked = got root. Guessing at some user's password doesn't count. Hacking some particular server (i.e. Apache) doesn't count since it is run jailed (unless the admin is an idiot) and therefore won't let you get root. There have been a VERY FEW true root compromises for Linux, each and every one has been patched within hours (if not minutes) of it being identified, and due to the differing culture around linux, it is a matter of extreme pride to publicly identify security issues, i.e. if you legitimately hack linux, you are most likely going to take full credit for it using your REAL NAME and probably even provide a patch at the same time. Hack windoze though and you release under a fake name using a secure proxy in russia or china, otherwise MS will sue your a$$ until you die of starvation either through judgement or through legal expenses.
In Linux, you are a hero for identifying a security hole and helping to bring the whole thing closer to perfection.
In windoze, you are a criminal for pointing out the ineptitude of MS.
Please be kind to me as this is my first post on XDA although I have been reading and utilizing these forums for quite some time. If this question has already been addressed, please let me know. I have already searched the forum and was unable to find anything on the subject but perhaps I wasn't as diligent as I could have been.
I left my G1 on the roof of my car and it fell off and was run over by a car. I already ordered a new one which will arrive in two days (I do nightly nandroid backups so all is well in that department). I would, however, like to donate the crushed G1 to one of the developers on this site so that they can salvage it for parts. Believe it or not, I was actually able to boot to the recovery screen and do a wipe (Alt-W). Obviously I could not see this as the screen is crushed but it rebooted after I hit Back+Home so I am pretty certain that there are some valuable working parts for someone who knows what they are doing.
I have taken advantage of the ROMs on this forum for awhile (Kavana's WinMo 6.1) as well as How-To posts (Apps2SD, Rooting G1, Nandroid, MAM, etc.) and countless other posts to keep my phone in perfect working order, and would like to give at least a little back to the hard working developers here. I would like a moderator to assist me in getting the phone into the hands of the right developer. I am sure it has some value to someone. I am pretty certain that the motherboard is in working condition as well as the keyboard and various other parts (it still vibrates on boot). I don't know much about hardware as I am largely a developer and a user. I don't want to take it apart only to find out that I have ruined what was once a good part. Ebay was an option but I figure that I will actually get more value out of donating it since XDA is literally my lifeline and smartphones would just plain suck without this site.
Please reference the attached photos. Sorry they are not so great. They were taken on my Dash because I was too lazy to take out my good camera.
Post replies here and we can go from there.

I am keeping the battery which still works. Now I have three! The battery door is crushed too. My goal is for the phone to better not just one person in need of parts but the community in general. If a developer can use this to help out the rest of us it will have been worth it.

A battery from HTC directly (after they first tried to deny my warranty status) is 37, shipping included.
As for a crushed device, I should try to find one in that condition since emulator will not run on my laptop. More or less the process goes make a program or update, open my sd card, load it, try it, improve it on the computer, delete the sd card copy, move the new one... very agravating.
Not to mention if you plug the device into the computer right, you can load your device AS the emulator (but I don't really want to do that to my "daily driver")
I would like to suggest a moment of silence to honor your G1.

Has anyone ever thought about whether it would be possible to increase the ram/upgrade memory in a G1. As outlandish as this might sound.. similar things have been done for a variety of devices.... if possible it would probably be the number one speed booster out there? or are there certain limitations out there that would make that impossible... Anyone ever opened up a G1?
This might be what you are looking for
http://forum.xda-developers.com/showthread.php?t=566410
Theres some ram on the g1 that isnt being utilized by default.. this hack, for specific roms, can push the g1 to use more of the rom that it initially comes with. as far as a PHYSICAL upgrade im not too sure how that would work out.. never opened a g1, due to warranty void
This does happen a lot nowadays. Original Xbox's (before v1.6) had extra 'spaces' for RAM chips.
Simple to do, if you can find the right RAM for your device, which was hard enough for the Xbox until a German manufacturer was found.
http://www.xbox-linux.org/wiki/Upgrading_Xbox_RAM_HOWTO
Edit: Also remember, this only works if there is an extra 'space,' piggybacking does not work 99% of the time (and I doubt there would be enough space within the housing...)
so the question would be is there anyway to open the g1 remove a ram chip and solder on a higher capacity one.... I mean wouldnt that be awesome...

There is nowhere to put it.
Ram and rom come integrated on the same chip: samsung k522f1gacm-a060
You need to find a compatible chip (as mentioned, the one from magic or hero *might* be compatible), you also need to program it with something... which you may need to hack together since there is no such thing as a dream with 256MB ram, etc.

I never said it wasn't possible. I simply said that what is there must necessarily COME OFF in order to put another one in its place.
And yes, you most definitely CAN program these chips outside the board, as long as you have the right equipment to do so, but the big question is to "program it with WHAT?".
Well according to this video our phone uses standard DDR ram made by Samsung. So I belive this is very possible.

As lbcoder has stated, finding a compatible chip isn't the problem.. it's a matter of what do you program onto the chip? Simply replacing the current chip with a blank one wouldn't do anything.
WELL, I don't know if this will work but I tune cars, where you use a eeprom reader get a dump off the old chip into a hex editor and then just burn it onto a new chip with changes made and just stick the new chip with new maps on it.
Would it be possible to do something like this with this chip? Just do a complete dump of one to another?

Yea thats the way it would be done. You'd have to hex-edit the dumped rom to address the right amount of memory for the new chip and it should work. I'm certainly not going to be trying this myself but it would be an interesting experiment.
Anyone know someone who has the smarts to do that... find me someone and I'll find you a few bricked g1s ...probably the only way to get them unbricked anyway.... or I have a g1 here whose wifi does not work. I bet you there are a ton of g1s out there where this or that does not work but that would be fully suited for something like that.
Anyway lets find a genius or a few that are brave enough to go where no one has gone before... I'd be pretty certain, that twice or four times the Ram would be a pretty dramatic experience.... imagine the possibilities with ram discs.... etc...

Believe it or not guys, my wife can do this. LOL. (I did marry the perfect woman, she also fixes my cars, folds the laundry and gives the best blowjob on earth). I digress <grin>.
If someone wants to donate a couple of bricked phones, I can get the chips swapped out. The issue of hex editing doesn't scare me at all I've been doing that for years, but finding the right addresses could be interesting. I'd probably need help with that as it is a lot different then bipassing a cd check on a video game
i work with embedded devices and here are my 2c about this, but take this lightly, I havent looked at how the G1 is setup on a board yet, nor do I know what hardware it is running.
if there is external ram, then perhaps it is a matter of swapping out the chips, given that they have the same pinout/packaging, etc.. if that was the case, you wouldnt get even another bit of more addressing because to get another bit, another wire is required to address it.
if the ram is internal on the microcontroller, then it would need to be swapped out, and good luck desoldering/soldering a BGA chip by hand. if you manage to find a new MCU with more internal ram to put on, the pinouts would have to be identical or else things might not work. additionally, you would need to have some method to kind of bootstrap the MCU because they typically come blank from the manufacturer.
Ok this is getting interesting... the easiest way to find out is probably contact HTC.. does anyone know someone, or is there a way to contact an engineer... or can anyone look up the specs? If it is using standard ddram by Samsung.. there might be a possibility.
Let me see what I can find for bricked G1's than we might have redir's wife take a look at it.. or John5788, if you'd volunteer. PM me your contact info...
We could just check the service manual, no?
edit: i tried to upload it, but the upload script here blows..
mediafire to the rescue! [download service manual here]
i just looked through the service manual, nothing specific about the ram/mcu locations. everything is just located on the mainboard without any sort of diagram. the people that look at the service manual dont need to know the device at that sort of hardware level.
Hi everyone
First I would like to thank the people who are here that make these awesome developments, I enjoyed them until today when I was trying to find a better
radio rom. I am/was using tytung's NexusHD2 NAND. I was going threw the radio roms listed in one of the threads and tried "Leo_RADIO_15.29.50.07U_2.06.50.04"
I had to get up for a second and when i returned about 5 min. later the phone was unresponsive. When I try to turn it on i can feel the vibrator motor spin for a split second and noda...No light with the wall charger pluged in or USB.
If anyone has an idea to what I did or what can be done I would be ever so grateful. This is my first smart phone and was so happy to have android running on it. I NEED it back. I've only had it for about a week and am lost with out it already.
I want to thank everyone in advance willing to give me some help!
Thanks from The NooB
Chris
I was reading some more and I'm sure its bricked but the PC does see it when its plugged into the USB...but it doesn't have drivers for it and it didn't have drivers for it before this problem.
I guess the problem is I shouldn't have loaded a TMOUS rom?
I thought It would be "OK" as long as it was a ".50" and not a ".51"
Such a sad day...first my little Leopard gecko broke her leg and then flying ants invade my house and go into my saltwater aquarium and mess that all up and now my new favorite toy is a fishing weight or new target.......I'm afraid to go outside to even go to McD's cause i'm sure i'll die somehow!?!?!?!
Someone please tell me there's hope.
I should have just traded it in for the G2X when I was up the mall today...
But I thought this Nexus NAND was the best thing in the world only problem with this phone was that I had no reception in my house.
Which is why I was messing w/ the radio in the first place...
If anyone figures anything out I'll be in the corner crying..
Thanks again fellas..
If you boot up with the volume down button held down, does it go into bootloader (tri-color screen, not MAGLDR)?
And does your pc have ActiveSync or Windows Mobile Device Center installed on it?
If you can get into bootloader, there is still hope...
Hey Huggs
Thanks for the the reply, No There is no bootloader screen, No nothing just a little blip from the vibrator motor for a tenth of a sec. when I try to just turn the power on, If I try to hold the Vol. key and power at the same time it wont do anything.
I did notice when I plug it into USB it try's to install drivers for a "QUALCOMM CDMA DEVICE" and after about 10min it starts to get warm near the bottom of the battery. I have windows vista so Windows Mobile Device is installed.
I left it go for about 4 hrs from 4am to am and then tried the battery again and again nothing, I'm pretty sure there's nothing I could do from USB.
Does anyone know if any JTAG will work or does it have to be the one I see people using, not the cheap Flea-BAY ones for $50?
also when using a JTAG do you have to have a special file or just the stock rom?
Or is there someone on here offering this service?
The phone never had reception in the house so I should be looking for other methods but this thing is like brand new and I would like to see it come alive.
THANKS AGAIN EVERYONE!
Sorry dude but you have 100% bricked your phone. You have no excuse other then lazyness as this is a very well documented fact and warnings against flashing and incorrect radio.
If you had taken time to read things properly you wouldn't have made this mistake.
Your only option now is to send it away for JTAG repair so they can replace your bootloader.
I wouldn't say its because of laziness. I looked up that rom and found a thread where people were using it. It was a ".50" and not ".51" rom and that was all I knew that was uncompilable.
Instead of starting the name calling or your this and that, How about some constructive criticism and say well "that particular rom isn't compatible because of"
I stayed up for 3 days strait and been reading for over a week trying to learn about flashing and what not. could I have spent more time reading YES but I flashed roms about a 2 dozen times and everything was OK. Like I said I used it because of the fact it was a ".50" and thought it was safe to use and the fact I seen the tread that it came from HTC and was safe to use. Guess not!
Thanks for your .02cents theatheist though.
Can someone tell me which JTAG box I have to use?
or what does the box have to support? I see others using the "RIFF BOX"
but 150 for a box is alot for one time use. does the box just have to support an arm7?
Again Thank you for taking the time to read this
Hope every ones have a nice holiday weekend
Can someone tell me why this particular radio rom bricked this phone?
and if anyone could tell me which JTAG box I would have to use?
would a cheap one from the BAY work?
what does the JTAG box have to support?
I am reading but I don't understand some of it.
Thank you for your time and reading this.
As soon as i finish posting this I will send you a PM with a link to someone that offers a JTAG service for $50 USD and lives in US. He is very good too, I would not recommend him if he was not very experienced with JTAGing HD2s.
I do not know why that Radio version brickedc your HD2 cause from what I know only the 2.04.50.xx or the 2.05.50.xx radio versions or the only radio versions with 50s that will brick a TMOUS. Looks like I might have to add 2.06,50,xx radio versions to that list. The reason why these radios with 50swill brick a TMOUS is because these radio versions were used in the Test TOM/Test T-Mobile HD2s which were actually regular HD2s and not the TMOUS that is out now with the extra ROM and RAM. There for these radios were not designed to run on the TMOUS.
Oh and you are correct about the %1 radio versions to0, they were all made for the regular HD2s also.
Thank you so much for your time Sir.
and thanks for the explanation, I would really like to try and JTAG it myself
do you know if any of the cheap JTAG boxes on ebay that support the ARM7 would work? I will shoot that guy a PM.
I hope you have a Safe Holiday weekend!

To be honest i do not know if the "cheap boxes" you refer to will work or not. Maybe a link to the exact box you are referring to would help.
I do know this if you want to try it yourself that is cool, but be warned you have to have a small torques head srew driver, a HTC HD2 JTAG, a Riffbox with proper connection cables, a Omnei Repair Tool (ORT), the software to use the Riffbox, and it is best if you have a small power supply for the mainboard but you can use the power from the HD2 battery. Plus you have to completely remove the mainboard of your HD2 to JTAG it, which means you pretty much have to totally disassemble the HD2.
So not only is JTAGing a HD2 just for yourself expensive, but you need to have some skill to do it as well.
PM the guy I referred you to is a very good idea, best of luck with however you decide to JTAG your HD2.
Thanks for the response...Your very helpful.
I didn't know If links were permitted.? Here's the link's
1&2 are the same but different prices, They both support ARM7 architecture Which I thought the QSD8250 was?
#1. http://cgi.ebay.com/JLINK-J-LINK-V8...155?pt=LH_DefaultDomain_0&hash=item4aab620ae3
#2 http://cgi.ebay.com/JLINK-J-LINK-V8...551?pt=LH_DefaultDomain_0&hash=item35b1f2c6e7
There is a RIFF for $150 that I found but I cant really pull that off ATM.
There is others that support the ARM also. I've also found a no-solder connecter for about 15 bucks but I don't know if the pin-out is the same on the ribbon cable as the ORT-JTAG box(company that has the connecter). I'm sure I could change it around If i could find a schematic for the both of them(connecter and box)
I do have the tools to dismantle this and power station(I also mess with the Arduino platform and circuit building when I have time and recently have just dismantled my HTC TP2 for craps and giggles and have fixed multiple IPOD touches) I have been also ripping everything apart that had a battery/wire connected to it since I could remember. And try to get it back together before my old man would come home and would find his stereo taken apart...
The only thing that has me is the programming part itself like the actual file.
I don't know if it's something special for the box or just the stock rom?
I have watched some youtube on it but nothing really helpful.
I'm thinking I could do it and maybe help some others if I could nail it and do some more reading. My brothers into IT(servers) and a HTC nightly rommer so I was hoping he could help he and I was really hoping for some help from you good fellas here.
I want to thank you for the PM (very helpful) and the reply.
I will probably end up sending it to him because it's about the same price and I don't have funds for a new phone if I toast it, and hes a very nice guy. I just love messing with stuff.
Have a good one.
Chris
To be honest I do not know if the JTAG Emulators your linked would work or not. It looks as though it might could but I can not saw proof positive it would work.
Ii seems like you might would be able to do it yourself. You have a lot of the needed tools. I think the software for the Riff Box comes with the Riff Box but not sure as I have never JTAGed a device. The software allows you to reload or as the program calls it "res-erect "the SPL, you see JTAG restores the bootloader and that is it. Then you just flash a ROM of your choice to the HD2 and you are good to go. But I do recommend you flash a stock Windows Mobile ROM just for precautionary purposes.
Yes you want the no solder JTAG that makes it a lot easier as far as the set up process.
Well being a noob in rom cooking, i have hard bricked my tab. It doesnt even turn on.
Im new to sammy stuff, so would appreciate some pointers, is this: http://mobiletechvideos.mybigcommerce.com/samsung-galaxy-tab-7-7-jtag-brick-repair/ the only way?
me and others flash the room from the stupied idiot guy in this post and got brick our devices, BTW i think he is working with the company you mintioned in web site, if like that he and the company are dirty.
any way, you are developer so try to recognize how flashing rom could make such problem. please.
the device have little hot in left side so maybe some hardware working ??thinking

Definitely not working for any company, and I have developed many Android ROMs and never had this problem. I've been here since 2005, for crying out loud. This is my first Samsung ROM, so I admit to being new there. I will even accept your "stupid idiot" comment, as I guess I deserve it. Although, I wonder why 150 people have downloaded it and only two or three people that I can see have been bricked. Something must connect those with issues. We need to find what it is.
Also, I am happy to pay for the de-bricking of those who are legitimately bricked i.e., followed instructions, have a receipt from JTAG, or whatever it is). Just PM me.
Steve
For reference, I am the only one who does anything for/with MobileTechVideos from a business stand point and two, I have successfully reverse engineered the world's (currently) only hard brick solution for this model as you will see above...

I have to apply the same rules for all. As the first post contains no development, it does not belong in said section

let us dry the tears and look forward to solve the problem.
steve, please pass the words came from reaction, it was chock as you seen. sorry for harming.
iam in middle east and not confidant to ship my device to unknown address because he mentioned in web page that he has solution, i mean JTAG and its not subject of who to pay steve.
supposedly that web site is true, and they didn't mention that they will change any part of device, what they will do to fix? the problem happened because we flashed non compatible files i think.
let us figure out the problem and try to find solution. right?

Absolutely. I understand. I have gotten into many messes since i started developing, and know that panic. I just need to know everything you.and the other user who had this problem can tell e about your device so i can find out what the common denominator is. So, confirm it is the wifi and 3g version you are using, and what build you are coming from, if you would. Are you using a sim card? Have you tried pressing power and volume up for a while? Thanks. Also, does your tablet feel hot at all?

Well I used yours as a base, just chopped the usual crap out, resigned, flashed, everything seemed OK. Initiated reboot, bam, doesn't turn on.
Charged all night, tab is hot along left edge, so I'm guessing still charging. 8600.

let us exchange the ideas
first we need to get the device powered so maybe remove and return battery could do something?? but how?
any external way to use it throw usb slot while charging ?
I would try pulling the battery but have no idea how to get the case off.
Steve, just wondering out loud whether those who have the hard-brick issue be because there are on pre-production hardware, so they have a slightly different hardware SKU. Hence your ROM does not work for them.

That seems to be the case for one of them. I am not positive about the others. I am having a hard time getting people to just tell me what build they were using prior to the flash...There seem to be 3 people who have had this porblem, and there must be something linking them, although it may be something random. Need to figure it out.

I came from P6800ZSKL2. Dont know if it was from the very first production line, but judging by the quality (i bought three, all with crap displays) they probably were.
Also, i believe the device is on and trying to unpack something because it is indeed warm.
This of course means that there may be hope of getting into download or recovery yet... i will drain it for 34 hours and then attempt to turn it back on.

Uh, not sure about the quotes, but yes, I am about to try something that might answer the question of why some bricked. If the answer is affirmative, however, the only solution likely is JTAG...

BTW, his "suggestion" was "incorrect." Still not sure what's up. Will keep posted, and like I said, I'll work something out with JTAG for those who got bricked yesterday and posted about in in the original thread before I responded.

For the record hard bricks on the Exynos 4210 will occur generally in one of 3 ways:
1) Mis-matched boot.bin and sbl.bin
2) Incompatible boot.bin and sbl.bin combo
3) Invalid PIT file flash from an earlier generation TAB or Galaxy S device
Anything else causing a black screen is simply hardware failure.
