Hi to everyone,
I bought the S860 -1GB version, and the only major drawback that I see is the 1GB RAM. Can somebody explain whats the difference between CN and ROW versions (beside the oblivious)? Is it hardware, software, or both. What are the difference in the ROM's of the two versions? It seems VERY strange to me, that LENOVO would go for two different assemblies, only excluding the memory chip. If this is the case, than I can easily solder the missing chip.
I am noob in Android development, but I understand hardware, so if anyone have interest in investigating, I can post pics of the phone's guts and see what's what.

I wouldn't advise soldering another chip to your tablet for an extra 1GB. If it's that important buy the ROW version but as far as I can see the 1GB is the only difference.
However it's still advised not to solder the chip as the controler for the RAM may be set for 1GB not 2GB

I have a htc touch pro that i want to gut and place in a htc g1 case a white new one. I have a non working htc g1 and i want to use that touch screen and the question i have the touch pro has a 528 mhz processor and 512 of rom and 288 of ram. I want to add the g1's 256 of rom and 192 of ram the the touch pro to have 768 mb of rom and 480 mb of ram is this possible. Also is there a way to use the g1's 528 mhz processor to make the phone a dual processor phone 2 528 mhz processors to make it super fast. Any help schematics guidance would be awesome.......
Thanks
Matt
No offense but. What are you smoking?
Resolution on both devices is different. So video chip versus screen incompatibilities would arise. Main board could not accommodate having or stacking 2 different ram chips. Also main board could not even identify or utilize 2 processors. Do you have extensive knowledge of mounting or removing surface mounted integrated circuits? Watch video below and wait till he shows the penny. And its way easier to mount an ic versus trying to remove one with out damaging main board or the ic.
good day.
Theres got to be a way whether its getting a new board and buying ram and rom chip sets and and mounting an existing processor or buying a new one as well. I figure if i replace rom and ram chips the phones existing os should remain intact or at least i think it would. Its an idea to build a phone with the hardware you want then unlock and flash an os of choice to it. I would love to find a gig ram chip and a gig rom chip and place a faster processor in it but i have a 528 pn hand.
You're proposing concepts that exist in pc building and modding. That just doesn't translate to mobile devices. Yes there are some older mods where you could send your device to a technician and he would turn your 64mb device to a 128mb plus that came with a noticeably higher battery drain. But I couldn't even imagine trying to unsolder the estimated 110 legs (which are about 5 times the size of a human hair) of a processor and expect that it would work after mounting it on another main board that may not be expecting it. Why do you think repair facilities just throw the mobo away and mount a new one or replace device. Because the guy hunting down the multiple micro ic's that might be bad and replacing them would get paid as much as a surgeon.
good day.
I need your opinion on tablet hardware. it seems like a good deal so i just want to run by you pro's for a quickie
It's name is Vivax TPC-7150, and it's a dual core 1,5ghz, 1gb DDR3, 7" tablet.
it has a rockchip RK3066 A9 cpu and Mali-400MP gpu, 8gb storage, wi-fi, 1024x600 at 169ppi (at 5:3 ratio) (dont know exactly is it ips or regular tft matrix. one site says ips, another site says tft)
2 MP front camera, microusb, microSD and 3500mAh battery.
on local pc magazine test ("VIDI"), it scored like this:
Quadrant standard
Total 4036
CPU 7278
MEM 4237
I/O 6011
2D/3D 317/2337
Vellamo HTML5/Metal 1655/523
PassMark
System/CPU 1811/5626
Disk/Memory 1152/1427
2D/3D graphics 2989/767
It sells from 110€ and it's a product of a chinese factory and engineered by a croatian company
any opinion will be useful, but ofcourse i'll have to check it myself somewhere in the store first...
edit: sry, here's a link
There probably won‘t be any gurantee or warranty with it. If you can live with that then... it might be a risk worth taking.
I have seen chinese tablets before which have specs that are different than the one promised on the box.
It's decent. You might be able to do better for the same money, but I can't say with what off the top of my head. The 5:3 is kind of weird. You might be able to get away with the 8Gb since it has an external SD slot - but consider you'll have to spend another $20 on that - and you can't put all apps and such on it.
If it is legitimate and that will be actually what you are getting, of course.
why do you think i cant put apps on microsd card?
and sorry for my misexplaining. It's a local croatian company (Vivax) that has "developed" the tablet and has it produced in china (like many other companies do), so i think there shouldnt be any problems with warranty....
what about rooting and flashing different ROM? how can i tell which ROM i can use and what tool to root it with?
I only have my x8 so i'm not so familiar with other devices...
can you please help me only with an answer for rooting and flashing rom?
can i flash any rom that is programmed for similar characteristics tablet? and is there a unique tool for rooting or is it device specific?

No. It needs to be made for you exact device or you will brick it and turn it into an expensive paperweight that will not turn on again.
Not all apps can be moved to the SD card. There might be ways around it, but it can be hit or miss and I wouldn't count on it.
I was wondering for light to moderate use which model between the 6gb and 8gb do you think would be more taxing on battery.
I'm assuming I would likely never fill 6gb as I close apps when not in use and only use a handful anyway.
What are your thoughts?
I'm no developer but if I had to guess, I don't think the difference in RAM has any effect on battery life. If it does, I'm sure it's so little it would be impossible to notice. Anyone who is more knowledgeable than me on this, feel free to correct me if I'm wrong!

Good question ! I was also wondering the same thing. Logically speaking there should be a difference but only significant if there are less physical chips on board for the 6GB model. I am very much inclined to order the 6GB model for a bit better battery life - 64GB of storage is plenty for me anyway.

Thing is, just like with flash storage, the controller and actual configuration of the chips will make power consumption vary wildly. We don't know the clock speed of the LPDDR4X RAM they are using, maybe it's different between the 6 and 8gb version.
Same as with the NAND chips, many factors have an influence on the electrical consumption and maybe they tweaked the 128 and 256gb version to be more energy conservative at the cost of speed.... speed that may be regained due to the fact that NAND arrays/strings are faster when there are more cells in them.
Then there's the use-case... IF the 8GB version has worse energy consumption values, maybe it still has better battery life because it can store more apps in RAM and has less need to constantly access the flash memory ?
TL;DR : we can make hypothesis but in the end there's just too much we don't know to really say if one is more energy efficient than the other.
more goods is better always !!
now with 8gb ram I can open all my apps and keeps them opened all day which will stress less processor power and keep battery.
Also, I need as much as possible storage, 256gb is ok for now.
We don't know how to get fine the kernel and OS for more ram, I would hope they would reduce compression so it strains the CPU less i.e. zram, or use the extra space to cache more things across the OS to keep things more consistent. I don't notice anymore apps open on the 8gb op6 Vs 6gb op5t.
In saying that my op6 has yet to use more than 5gb ram
ram uses the same power regardless
if the chip is the same - both use the same amount of power
only difference will be one can have more apps in memory than the other (assuming you can fill 6GB of ram... on a phone...)
other than that zero difference
Considering how experiences on the battery related threads seem to vary wildly, I wonder if this is the cause?
I was considering downgrading from an 8Gb version to 6Gb, but if I plan to keep this phone for a few years is it better to hold on to the 8Gb?
3Gb seemed like overkill when I first got my OPO but now it is less than some budget phones provide.
My OP6 - 6Gb close Google Maps and Sportify with 2,1 GB free...

Nothing to do with battery life, but there seems to be some very aggressive ram management on the OP6 which affects the 6Gb version much more than the 8Gb: https://youtu.be/t5UEN2vpchQ
Maybe I will keep the 8Gb version after all.
My Nexus 5 has always full Storage and it p****s me off. I searched for Storage Upgrade posibilities and found a thread from a dude upgrading his storage to 64gb. So i decided to try that too with an spare nexus 5. I also found a post about nexus 5x users upgrading their ram to 4gb. So I researched and found out that the Nexus 5 uses the "H9CKNNNBPTMRLR-NTM" RAM-Chip.
It says that it has 216-ball fbga socket and i searched for similar chips with 216-ball socket with more capacity. Since the snapdragon 800 is a 32-bit chip it'll "only" support 4gb ram (I suggest). I found the "H9CKNNNBPTATDR" and need to know if it has the same pinout as the "H9CKNNNBPTMRLR-NTM".
I cant find enough information about the chips and contacting the Manufacturer doesn't work for me (cant register somehow). Maybe one of you is a dev in a company, which can get into contact with the chip manufacturer. Or you are just better st finding datasheets than me
Hope you can help me
Hello guys
My cellphone's ram is MICRON brand and Im very upset about that because all note 6 pro use samsung ram expet my cellphone !!!
Do you know whats the difference between them?
and which one is better?
I dont know why Xiaomi change the brand of ram ?!!
Both are high quality RAM brands, there's nothing bad about Micron. As to why Xiaomi changed brands, I can only guess either Samsung couldn't deliver enough chips or maybe Micron cut them a better deal.
Both maker can produce those low specs RAM chips very easily, they have decades of experience so I doubt there's any difference on paper.
If you have both part numbers, you can find the datasheets online.
