Guest tcpaulh Posted October 22, 2013 Report Posted October 22, 2013 Ok, I hope Dazzozo doesn't mind me posting this. It looks like we need a volunteer, a guinea pig, a brave tester who has a g300 with Hynix memory. Worse case scenario is that your device could be bricked to the extent only a service centre or riff/jtag box could recover it!
Guest tcpaulh Posted October 22, 2013 Report Posted October 22, 2013 (edited) To find out what memory you have installed, copy the following into the terminal emulator app: cat /sys/class/block/mmcblk0/device/name xinyh = Hynix Edited October 22, 2013 by tcpaulh
Guest wards5150 Posted October 22, 2013 Report Posted October 22, 2013 Can someone explain the difference between the two memories.
Guest dalyer Posted October 22, 2013 Report Posted October 22, 2013 (edited) Can someone explain the difference between the two memories. Probably not unless somebody has the actual part numbers in which case the datasheets can be looked up. But in general different flash chips may have different pinouts, voltages, erase/programming sequences etc. There may be more info in the IRC logs but as far as I can see the XINYH chip is a most likely a Hynix (the clue is in the name :)) and the SJS00M chip seems to be a Samsung according to a Google search. But without specific part numbers it's difficult to say anything else - unless somebody knows the "most common" (?) Hynix/Samsung "eMMC" chips used in phones or something...?

Guest dalyer Posted October 22, 2013 Report Posted October 22, 2013 Thanks. Is it actually KMSJS000KM? http://www.samsung.com/global/business/semiconductor/product/mcp/detail?productId=7525&iaId=860
Guest rhen Posted October 22, 2013 Report Posted October 22, 2013 (edited) yes, you are right.but what eMMC(4GB)+MDDR(4Gb) means?I search for eMMC(4GB)+MDDR(512MB) thinking that MDDR is RAM. Edited October 22, 2013 by rhen
Guest george109 Posted October 22, 2013 Report Posted October 22, 2013 yes, you are right. but what eMMC(4GB)+MDDR(4Gb) means? I search for eMMC(4GB)+MDDR(512MB) thinking that MDDR is RAM. Maybe its short for Mobile MDDR https://en.wikipedia.org/wiki/Mobile_DDR
Guest rhen Posted October 22, 2013 Report Posted October 22, 2013 Maybe its short for Mobile MDDR https://en.wikipedia.org/wiki/Mobile_DDR I think the same, but G300 doesn't have 4GB memory for sure :)
Guest tcpaulh Posted October 22, 2013 Report Posted October 22, 2013 I think the same, but G300 doesn't have 4GB memory for sure :) It does, in total.
Guest george109 Posted October 22, 2013 Report Posted October 22, 2013 (edited) I think the same, but G300 doesn't have 4GB memory for sure :) It does, in total. There is 2 point something for the internal SD card, 700MB for Data, 350 for System, 800 for cache and about 150 for something else! I assume that Huawei get the memory and RAM separately... Edited October 22, 2013 by george109
Guest rhen Posted October 22, 2013 Report Posted October 22, 2013 It does, in total. OK, but eMMC(4GB)+MDDR(4Gb) is 8 GB total and this chip is in my G300.
Guest tcpaulh Posted October 22, 2013 Report Posted October 22, 2013 That was my first thought. I'm not sure but I think it refers to two different options. One or the other but not both.
Guest dalyer Posted October 22, 2013 Report Posted October 22, 2013 (edited) It's 4GB(ytes) of eMMC + 4Gb(its) of RAM. 4Gb(its) of RAM = 0.5GB(ytes) or 512KB(ytes) of RAM. This matches the G300 specs exactly. The B and b make a difference! :D The Samsung part mentioned above is an eMCP - embedded Multi Chip Package with eMMC and DDR dies in a single package. You can get more general info here: http://www.samsung.com/global/business/semiconductor/product/mcp/overview And I posted the link to the page for the specific part used in the G300 above. http://www.modaco.com/topic/365989-req-guinea-pig/#entry2167537 I presume that there's a similar (pin compatible?) Hynix part used in the other G300s but I haven't been able to figure out what is a likely candidate part. Edited October 22, 2013 by dalyer
Guest wards5150 Posted October 22, 2013 Report Posted October 22, 2013 Thanks for all the info. It amazes me the wealth of knowledge on this forum. Looks like I am a lucky one with the Samsung chip. As a thought I have done a lot if flashing on my phone with no trouble. Not one has my Imei code been set to zero. Just putting out a suggestion as to why some have been bricked while others have not.
Guest tcpaulh Posted October 22, 2013 Report Posted October 22, 2013 Heh, that small b eluded me /theshame
Guest tcpaulh Posted October 23, 2013 Report Posted October 23, 2013 Probably no more nightly builds till someone steps up. It's a tough one.
Guest matskevichm Posted October 23, 2013 Report Posted October 23, 2013 (edited) Probably no more nightly builds till someone steps up. It's a tough one. Why no nightlies on 3.0.8 like it was before?, i can live with small green camera problem. Speed, functionality-all fine. 3.0.8 not so bad for me and for this phone. Edited October 23, 2013 by matskevichm
Guest dalyer Posted October 23, 2013 Report Posted October 23, 2013 (edited) You mean 3.0.8 kernel? Has somebody determined that it is the 3.4 kernel that is the issue here? I didn't see that anywhere but admittedly haven't checked the IRC logs. Edit: just checked the IRC log and it looks like the 3.4 kernel is suspected alright... http://g300.valicek.name/show.php?day=2013-10-22 Dazzozo 3.4 kernel 15:53:55 Dazzozo on mmc chips 15:54:01 Dazzozo reporting themselves as XINYH 15:54:05 Dazzozo which is hynix backwards 15:54:08 Dazzozo die Edited October 23, 2013 by dalyer
Guest tcpaulh Posted October 23, 2013 Report Posted October 23, 2013 But also: tcpaulh Lol. Can assert script determine memory type? 14:27:36 Dazzozo you could probably do something like that 14:29:42 Dazzozo but its the recovery causing the issue
Guest dalyer Posted October 23, 2013 Report Posted October 23, 2013 OK - thanks. I just skimmed the logs....
Guest tcpaulh Posted October 23, 2013 Report Posted October 23, 2013 It's a thorny issue. I can't pretend to understand it fully.
Guest Gabriel94 Posted October 23, 2013 Report Posted October 23, 2013 Sorry, I'm lucky I have the Samsung RAM, SJS00M
Guest dalyer Posted October 23, 2013 Report Posted October 23, 2013 Sorry, I'm lucky I have the Samsung RAM, SJS00M It's not RAM - it's the eMMC that's at issue here. http://www.modaco.com/topic/365989-req-guinea-pig/#entry2167757
