Is it possible to put the newer MSM7201A (the one in the new touch diamond), into a tilt's chip location and have it speed things up a bit? (528 vs 400 Mhz).
no as the chip is intergrated into the motherbaord.
Sure, with a very steady hand go on & solder it in, LOL
Not a problem
I have access to both the needed equipment, and a clean room to do it in. So that doesnt worry me, i really meant, what is neccesary to do so other than place the new chip. Will the software immediately recognize the difference? Or will it be a pain to make it work?
Blunt reply.
If you have to ask you don't have the skills to do it.
hah
I do it all the time for my PhD work. Really the physical work is not an issue at all.
Out of curiosity, where would you get the replacement MSM7201A chip? Assuming you are capable of replacing the CPU on a motherboard the size of the phone then you would also be capable of determining from the spec. sheet the similarity between the two and likelihood of utter catastrophic failure.
Personally I have no idea how feasible it is (sorry), but I would love to see someone potentially ruin their phone trying to be proven wrong

LOL exactly. You're going to have to buy a phone that has the MSM7101A chip in it already. Then your going to take the chip out of a perfectly good phone that is not even out yet mind you and then place it in the Kaiser. LOL. I just don't know why you would actually want to do this.
Here are my computer's specs:
http://h10025.www1.hp.com/ewfrf/wc/...4322&cc=us&dlc=en&lc=en&jumpid=reg_R1002_USEN
Only difference is that it's been upgraded to 4Gb of RAM.
My issue is this: My cpu cooling fan recently died and my comp has been overheating and shutting down. Under load it's been as high as 97*C before shutdown. Obviously I need a new fan but getting THAT hot has to be bad for the CPU so I might as well upgrade while I'm in there. I was just told by HP support that my motherboard (Narra2-GL8E) will only handle CPUs from 45W to 65W. I was really hoping to upgrade to amd 64 x2 6400+ processor but according to them it would be wayyy too much for the motherboard. I'm operating under the assumption that the rep was full o' **** and feeding me some standardized response so as not to encourage me to do something that *could* possibly be damaging to my pc.
My question is what's the best processor can I realistically upgrade to with my current set-up??
I've got the Pavilion Elite m9402f, almost exact same specs, except it has 7GB of RAM, and runs at 2.3GHz. Watch that GPU, it sucks! Seems like the NVIDIA card isn't supplied with enough power. It prob isn't the reason for the overheating, but if you use any graphic-intensive apps/games, it may not help the issue.
Believe it or not, but the HP rep may have been correct. Your motherboard won't support CPU's with the designation AM2+. When AMD released the AM2+ CPU's, they intended them to be backwards compatible with existing AM2 motherboards. However, most manufacturers have refused to release the BIOS updates to allow this.
http://en.wikipedia.org/wiki/Socket_AM2+
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01080282&lc=en&cc=ca&dlc=en&product=3445425
The 6400 is a special CPU that actually should have been released for the AM2+. But since the HT speed is the same as your stock processor, the wattage won't matter. I will warn you, the 6400 has been known to have severe overheating issues. You'll likely spend a good chunk in a high quality heatsink/fan for the processor.
The HP site doesn't list a PSU. What is the rating on yours? That may be what the rep was referring to... I couldn't imagine HP building a machine with more than enough wattage for the internal components. Usually PC Manufacturers cut those things pretty close to keep costs down.
I ended up deciding to err on the side of caution and bought an x2 5600+ processor to throw in there. My power supply is only 250W and that's definitely on the list of things to replace. Gonna need a better power supply to put a half decent GPU in there. Going to install the new CPU and heatsink/fan tomorrow and see if that doesn't help. I have a feeling there are other issues though...to be continued..?
**As a confusing little edit to the situation..upon closer inspection it turns out that the cpu fan IS actually working. So now I'm even more lost. It's understandable to run hot with no fan..but with a fully functional fan?!**
When the OMAP boots up it hashes a public key and compares it with a series of blown fuses. If they match then it uses the public key to verify the first stage bootloader. A novel idea idea is to swap out the OMAP 4430 from a development board with the chip inside the phone.
Forget that handsoldering BGA is difficult because I have heard of it being done. What differences are there between the a development board chip and the processor in the Droid 4?
Bumped.
Does anyone know of any instances where someone was capable of hand soldering a BGA chip like an OMAP?

Really, hand solder something that small?
Sent from my HTC_Amaze_4G using xda premium
hot air rework would do it, wouldn't it?
i did something simpler to replace the nand chip on my ps3 bluray drive, cant imagine this chip being to much smaller.
It could be done; I've done quite a bit of soldering with ultra-tiny contact points such as those you'd find on SMD-components. You'd definitely want to use a loupe (one of those monocle-style magnifying lenses that you always see the bad guy in cheesy movies analyzing diamonds with... hehe).
I'd be really interested to see if anyone could pull this off.
Really kind of a novel plan of mine for bypassing signature checks. Only problem is getting my hands on a chip without being being an OEM.
You're looking for the Pandaboard, available for $174 here http://www.digikey.com/product-detail/en/UEVM4430G-01-00-00/UEVM4430F-01-00-00-ND/2349866?cur=USD and http://www.mouser.com/Search/ProductDetail.aspx?qs=ySz5i1dyTooQYPawsE8fWA==

Hi everyone!
After months and months, and countless hours spent (and a good deal of destroyed Nexus 5 motherboards...) ,I have succeeded in expanding both RAM and storage of a Nexus 5!
The RAM:
I have been thinking about it for quite some time, then I decided to go for it, so I bought a 24Gb LPDDR3 memory chip from Aliexpress and attempted a replacement to my spare Nexus 5. Well, believe it or not, it worked!!! My N5 has 3 GB of RAM, and the difference, with my 242 apps installed, is very evident! It has been hard work, not easy at all, but if there is anyone who has the necessary skill/equipment and is wondering if it can be done, well, the answer is YES!
The memory chip I purchased is the K3QF7F70DM-QGCF.
Replacement requires removing the ePOP memory from the top of the Snapdragon chip, then cleaning carefully the BGA land pads from any resin/glue residue, then re-soldering the new chip. I am not going into details (unless requested) because those who know about BGA reworking know what it is all about and those who don't... Well, don't try it! Anyway, I am available to provide any further explanation.
The Flash:
Then... I could not stop there. RAM is nice, but I was running out of storage space... Plus, it seems it had been done before, even if not many details had been provided... Well, there is all sort of documentation and software one can desire for the Nexus 5... So let's go for it! Let's buy a 64 GB eMMC chip from Aliexpress and let's try to transplant it!
The operation has proven more complex than I could have imagined: I collected 13 (!) dead Nexus 5s so that I could experiment with them, I fixed some of them and then I destroyed them again in the attempt to transplant the chip! The endline is: "Don't try this at home unless you are willing to end up with a broken phone"! And, believe me, it is VERY likely this is going to happen!
But the screenshots speak for themselves:

https://photos.google.com/album/AF1.../AF1QipMCqe-Xn4x5l6PRykQDxyRnVhrbxZqTU0ZGumd4
If anyone is interested (be careful if you want to attempt the mod) I will provide all details of hardware equipment used, how to desolder chips, how to solder the new ones (but if you need to read my instructions then the operation is clearly out of your reach!) and how to flash the new chip with bootloader, recovery, ROM and everything. Just let me know!
Regards!
Hello, can you show in more detail and with screenshots where you soldered the memory. how long did it take you
Did you take any pictures through the process?
Hi guys,
unfortunately I have not taken any pictures, because I had not the slightest confidence in the outcome! However, I can summarize the process with pictures found online:
1- the memory chip (which is on top of the processor) is the one with the red dot on it; you must also remove the metal shield around it, which is fitted with just clips, so a small screwdriver and some care is enough to remove it;
2. you must heat up the chip with a hot air rework station; I also recommend to cover the rest of the board with kapton tape (or, at worst, with some aluminium foil);
3- use a thermocouple if possible; if you don't have it, monitor carefully the melting of the memory chip. Keep in mind you have to remove the memory only, not the entire chip (but the memory chip, being on top, is the first thing to come off);
4- using a needle or a thin razor blade, gently leverage one corner of the chip until you feel it softening and finally coming off;
5- after removing it, you must very carefully clean the pads from any glue left on them (yes, the memory is also glued!). The pads are not too delicate, however exert maximum care, you do not want to rip any of them off; I personally used the scalpel tip of my soldering iron to clean and level the pads;
6- use isopropyl alcohol, acetone and some sandpaper or a pencil rubber to clean the pads from any dirt and oxidation; you must end with some very clean pads, as in the picture (of course pads will not be gold but silver);
7- spread some gel flux on the pads and place the new chip on them, carefully aligning it with the processor underneath (careful about pin 1!);
8- heat up the chip again with the hot air gun; look at it from the side, until you see the balls melting and the whole chip settling down in the correct position;
9- remove hot air and let it cool nice and slow;
10- enjoy!
Please note that the process is extremely risky and complex; if you need to read the above steps, probably you should not attempt it; but if you succeed, results are worth the effort! The whole process took about 1-1.5 hours (I do not know exactly).
Next step will be to upgrade storage space (someone has already done it, if I remember correctly)!
If only i had rework station. I have broken display connector. 8 or 9 pins came off. I need to solder them and i do not have equipment. What is the cheapest hot air rework station i can get?
make youtube video, you will be a legend, really, my phone was stolen while leaving work, xiaomi mi6 6gb ram (powerful) and unfortunately I had to buy a lg g2, do you think you can add more ram to g6 ?, I'm very used to the speed of my once loved mi6: /, do the process please, it would be great!

I do not recommend hot air on that connector. It is very prone to desoldering, but your best bet would be a very thin soldering tip, like the Weller LT1S, for example.
As for a cheap hot air reworl station, this is a pretty standard one:

or even cheaper:
https://it.aliexpress.com/item/High...a0-4569-8e61-9b85979280bd&transAbTest=ae803_5
you will have to build your own stand, because it is impractical to hold it in your hand (you will need both at a certain point!). I attached it to a desktop spring loaded lamp, "Pixar style" to be clear.

I have ordered a new 4 GB memory chip, this time I will make a video when I attempt the mod!
can you please clarify to which device you would like to add RAM?
how about geekbench result?

Amazing! :fingers-crossed:Waiting for that!:good:
The new Snapdragon 801 has just arrived (yes, I am attempting to transplant that, too!), while the memory chip should come in any day now... Please stay tuned for some wild modifications! ?

It would be awesome if it worked, really awesome. But I don't think it will work right of the bat. A different processor will most probably need an update in the kernel code to accommodate for that hardware change. I think that this hardware change is significant enough to require an change in the kernel source. Same goes for upgrading the internal storage.
Actually, the Snapdragon 800 and 801 are pretty much the same processor with some very minor differences, so I would expect them to be swappable. The first attempt, however, has proven to be a real disaster due to the fact that all BGAs are glued to the PCB with some strong epoxy and removing them is really hard, because it is difficult to understand if the chip is holding on to the glue or if temperature is not high enough... So you raise it and raise it to the point the PCB gets delaminated... So I am waiting for a new PID and a new thermocouple so that I can monitor the temperature more accurately!

Maybe you're true about the processors, I hope you are it will make it much more easier for you . But is the difference between them really worth the effort? As far as I remember, it's just a slight increase in clock speeds (for both CPU and GPU).
I remember I saw someone on Youtube who upgraded the internal storage of their iPhone to 512 GB, he had to create new partition tables for the new storage chip. If my brain doesn't fail me, there's someone here on XDA who also managed to do it for the Nexus 5, he also had to create new partition tables and done some flashing for some stuff that were required to get it to boot. I'll try and find the link maybe it would help you
I'm really interested to see how much further can you push a Nexus 5 before it reaches its limits
Edit: Found it! Check the thread here. It was also featured on XDA news
Ok.

Jeezus, maybe 805 and with and it is a mini Nexus 6? xD
Hi all,
here I am back after quite some time, to report results which are disastrous to say the least. In the past week I have collected some malfunctioning Nexus 5 (some with broken switches, other with broken screens, others with broken eMMC chips), fixed some of them and then attempted the mods I had dreamed of, unfortunately so far I have managed to destroy them all, and must conclude that my very first attempt when I successfully swapped the original RAM chip for a 3GB one has been nothing but a lucky event and that my ability to perform such mods has been overestimated.
To summarize what happened so far:
1- attempt to replace the SD800 wirh a SD801 and concurrently mount a 4 GB RAM chip has ended up with a destroyed SD801 and a destroyed RAM chip;
2- 2 attempts to replace a defective eMMC chip on a working SD800 ended up with a non functioning phone;
3- replacement of a defective WiFi/BT chip succeeded, but the subsequent attempt to replace the eMMC chip ended up with a non functioning phone;
4- replacement of RAM chip with a 4 GB one ended up with a fried SD800; unsure about the RAM chip.
I am not giving up though; I am still convinced that it can be done, and that it is only a matter of finding the right way to desolder and then resolder memory chips... I am continuing experiments and collecting cheap damaged Nexus 5 phones. If you have one you can spare...
Here I am, and this time with great news! Finally, after 13 motherboards sacrificed in the name of knowledge, I have succeeded in expanding both RAM and storage of my Nexus 5! See OP and, if interested, I am willing to provide any detail you require!
Regards!
