Mar 2nd Update

Sorry I didn't keep this post update regularly.

But I didn't rest. I have already gathered more than 200 people in China fighting against Samsung over the N7102 Baseband issue. (QQ group 289956485 )

We are trying in every possible way to push Samsung, and force them to face us.

We already have a lot of media following this issue about Samsung's false advertisement, and we are trying to taking Samsung China to the court as well.

At the same time, Samsung is trying to stop us.

They negotiated with a lot of medias to stop their news on their website and megzine.
They bribed most of chinese video hosting site to delete my demonstration video.

We will not stop !

Here's two things that you can do if you want to help us:

1. We are trying to gather as many as possible signned paper to file 315 report.(BBB in China)
download the docment below, sign, and send to our email 631265979@qq.com


2. If you live in New York, please contact me right away. I hope we can have some people go to
March 14th's Galaxy S IV lauch event with a big sign to tell Samsung head office, N7102 have a problem.
I beleive if Samsung Korea or their head office are aware of these issue, a solution will come out very fast.

--------------------------------------------------------------------------------------------------------------------
Feb 16th Update

After took apart the N7102, the Base Band chipset in the phone is Qualcomm ESC6270+ Intel XG626

Intel XG626 supports GSM 850/900/1900/2100 + WCDMA 850/900/1900/2100 without a problem, a lot of phones are using this chipset.

But I can't find any information about Qualcomm ESC6270

The only thing I found is a LG C320 phone with repair manual HERE

This phone use ESC6270 with Support GSM 850, but in this manual, some places says it has ESC6270, some places says it has QSC6270.

If any one can figure out more from here, please let me know.







--------------------------------------------------------------------------------------------------------------------
Original Post


According to 60 pages thread in here,

the conclusion is N7102 will not work on 850 1900 WCDMA in Slot1 and 850 1900 GSM Slot2

I already sent report to Samsung China official website, and hope they can finish the update soon


===========================
here is a possible way that might let the 850 and 1900 work. But with current ROM version, it's not working.

May be we can try flash international N7102 rom instead of the China Unicom one.
I don't know where to find it tho...
=============================

Summary of the Problem:

Micro Sim, Slot1
Should be
GSM 850/900/1900/2100
Plus
WCDMA 850/900/1900/2100

Actual:
GSM 850/900/1900/2100 ALL works
WCDMA 900/2100 works
WCDMA 850/1900 not working


Big Sim, Slot2

=============================
There are two ROMs for this phone. The China Unicorn and the other Chinese. I'm using the other, but I live in Europe and can't test 850 and 1900 bands. However I see, that the band selection menu has had some changes lately. So they might working on it. I guess there must be some Chinese people traveling to the US - at least from Hong-Kong - who want to make use of their phone out there. Or from Taiwan or Korea...
I suspect the hardware must be capable of handling those bands. I don't believe Samsung would ever produce intentionally a non-quad band phone...

I'd put it that way, the questions are :
- is it a HW related issue: embedded HW doesn't support other bands than 900/2100 then you are stuck with Slot 1 WCDMA 900/2100/Quad Band GSM and Slot 2 GSM 900 2100.
- is it a SW issue : then it could be at 2 levels: Radio chipset firmware (which seems to be reconfigurable using QPST tool, but no proper qcn file for now ...) or ROM level (using a different modem file when flashing).

If anyone has "the guts" to open his N7102 to take a look at the chipset (or knows a way to fins out what radio chipset is in there).... This could answer quite a lot of questions...
Galaxy Note 2 - N7102 (dual active sim, dual standby) - Stock ROM
Samsung Captivate Glide - I927UCLG9 - 4.0.4 ICS - "Official" Leak
HTC Rhodium (Touch Pro 2) - WiMo - ROM : 1.86.406.1 FRE, Radio : 4.49.25.17

i'm sure the radio is h/w base, but needs the s/w or drivers to enable it, thats if samsung has disabled the band.

I have official response from Samsung support team about wcdma/gsm 850mhz frequency support in N7102.

尊敬的三星用户,您好!



非常感谢您对三星电子及三星电子产品的关注!我是三星电子在线服务手机产品组负责人。



您本次邮件中咨询的问题是:N7102不能在美国使用。



您好,很抱歉给您带来不便了,此款N7102是联通的双卡双待手机,由于不同国家地区电话卡的制式是有一定 区别的,对于美国的电话卡能否使用,需要您联系美国电话卡网络运行商确认。



此款手机支持的网络频段是:WCDMA:850/900/1900/2100MHz;GSM:850/900/1800/1900MHz。对于国内卡在美国能否使用,需要取决于美国的网络频率和手机的网络和网络频率是否一致 。 国内电话卡需要开通国际漫游业务。



美国是一个多频率的国家,不同的州之间网络和网络频段可能会有所不同。由于美国的网络或网络频率我们没有相 关信息,请您联系您当地网络运营商或办理签证的地方咨询。



联通的3G卡需要插入卡槽1中,使用联通3G网络信号,需要满足以下条件:



1.需要使用联通3G卡,并且周围有联通3G网络信号。


2.更改网络模式尝试:设置-更多设置-移动网络-网络模式-WCDMA。



3.建议您更换其他位置尝试。







非常感谢您对三星电子以及三星电子产品的支持,希望我们为您提供的回复对您有所帮助。

Samsung China might want to test out their units and verify first before they respond. That reply seems like they didn't even investigate, just wrote something to say that they replied asap.

There is no official email of Samsung support. To send them an email you need to open N7102 support page on samsung.cn website, then open email support, choose needed criteria and send email request to them. I used google translate.
