[Q] New N900 has bad signal and "your device has been modified" update error

[Q] New N900 has bad signal and "your device has been modified" update error
Hello forum,
I am in the UK using a Virgin sim and my girlfriend bought this phone new in china and flew it over to me. At the moment the signal is really bad wherever I go (the same SIM card in my old galaxy nexus had great signal in all these places) so I was wondering if there was any way to make the signal better?
Also I tried to do an update through the settings menu hoping this would sort out the signal problem and it is giving me the "your device has been modified. no updates available for this device." error even though the phone is new.
the information about the device is as follows:
when I type *#1234# I get:
AP: N900ZSUBMI5
CP:N900XXUBMI2
CSC:N900OZSBMI2
In my "about device" within settings, the following is given:
Model number: SM-N900
Android version: 4.3
Baseband version: N900XXUBMI2
Kernel version: 3.4.39-1625296
[email protected]#1
Wed Sep 11 19:49:31 KST 2013
Build number: JSS15J.N900ZSUBMI5
SELinux status: Enforcing
If I reboot to recover it opens:
CWM-based Recovery v6.0.4.5
Compiled by Xiaolu(20131121)
When I try to check knox I cant see it (I go into odin mode and the top left just says the following):
CURRENT BINARY: Custom
SYSTEM STATUS: Custom
(I now understand the N900 doesn't have knox)
Thanks for looking, any feedback at all would be much appreciated :good:

Well it looks great. At least I can be sure that your phone shouldn't be a fake. It is of Hong Kong or Taiwan origin, Exynos, running 4.3 on N900ZSUBMI5.
You have CWM Recovery, Xiaolu's port of it. Hence that device was probably rooted prior to getting it handed over to your girlfriend. KNOX is only present on the MJ and onward firmwares, and you happen to be on an MI firmware so you don't have it activated yet.
Check the section for Network/Bearer and Wireless Connectivity on this link: http://www.samsung.com/levant/consumer/mobile-phones/mobile-phones/galaxy-note/SM-N9000ZKEXSG-spec
Match it up with your country's network specifications. There's a reason why these phones don't get sold worldwide, as they aren't all compatible with every region. Also remember to set correct APN values for your country.

okay thanks for your reply, I believe the frequencies virgin use are 1800MHz and 2100MHz which can both be used with this phone. The APN settings were downloaded automatically when the phone was first booted and I also manually checked them and they are correct.

What is your network switch options in Settings?
Do you have it to HSPA/GSM (auto connect) set? [Sorry if it's not exactly the same, I don't have the N900 model]

My friend pointed this out to me just before I saw your message, the options available are only wcdma/gsm hspa isn't an option. Im guessing from my limited knowledge that this is the problem, what is it I would need to do to fix this? thanks again.

Actually, I asked my friend who has the N900, he's reporting the same as you. So no problem in that.
There must be something else that can be isolated to find what's going on. You can try to upgrade the phone to the latest modem by flashing the latest 4.4.2 ROM.

Okay, what would be the best way to flash the latest ROM? Would this be a custom ROM or is there a way to get the official one? Thanks again.
Edit: I have now tried putting Dr Ketans rom on it, telling it to use the ROMs modem, and that still didnt fix the problem. I have also tried flashing some other modems from the GSM modems collection thread but the problems persist. The symptoms are as follows:
Frequently looses signal
only ever shows the E or G symbol for mobile internet connection (whereas on my other phone with the same sim it instantly gets full signal and shows H+ or 3G)
the phone has also never been able to lock onto a GPS location it only ever shows searching for GPS in the notifications bar.

Lenovo K920 (vibe z2 pro) Baseband version: unknown

Hi, i have (or i had ) a lenovo k920 (chinese version) i have installed via qfil a modded row rom. After that it won't read sim cards anymore (it show only two red cross). by typing on the dialer *#06# i sow that both IMEI was lost (both value was 0) so i replaced the right ones with a little software found on the net. It still won't read sim cards and i noticed that in "version information" it show Baseband version: unknown.
I have done anything: reinstall modded rom, back to stock rom, try another rom...but nothing changed. Please someone can help me?
ty and sory for my English.

ROW software won't work on chinese version of the phone. The radio is different so it uses different software. Therefore you cannot get SIM signal. Flash CN rom, root and debloat manually. That's what I have found to work so far...

Hello, I bought the k920 (china mobile 4G) new from a chinese friend who bought it for me in china. It came pre-manipulated for the international market with K920_ROW_S226_150429_TWRP_ROW.zip , MODEM_CN1.zip and SuperSU_for_K920.zip still left on the internal storage. I got access to all the network types and only the telephone function doesnt work somehow if LTE is enabled. It seems like the network types are also not able to switch between eachother at loss and gain of signal strength. So I am wondering what methods the chinese guys used to achieve my set-up... Baseband version is DI.3.0. Build number 226 and Android Version 5.1.1. And I checked my bootloader and it seems like its locked, according to the adb output ( fastboot oem device-info)
Thanks in advance... EDIT: and sorry for necro bump.

From the hospital: SIM not working. Also, it it really i9500?

Hi
Background: I am usually very thorough when buying a new phone. This time I Wasn't well for many days and in the hospital. Urgently needed a new phone and ordered 1 online from a used shop. I specially wanted i9500.. no other variant..
I got one, it said i9500 on the back cover (echted in the plastics and well as the paper... which said made in india.. also the paper/sticker wasn't samsung quality but maybe since it was used, and indian made, i thought ok..
Now I inserted my sim and turned it on... Some chinese s***t! then samsung logo then the TouchWiz.. But there were many chinese apps as well. AND IT DID NOT DETECT MY SIM. Settings say its an i9500.. it felt like a samsung but something was off... In camera, as soon as I took a pic, phone got shut off! Had to take out battery... (btw, it says android 4.42 and when I go to Update.. .Samsung says it cant as device has been modified)
reformatted phone... more chinese sh*t, then Android loads up and there is no play store!
So I downoad a Darky ROM for i9500 and try flashing.. viola!! success.. Android 5.0.1
It said Sim not registered... then that message dissappears and now it shows me FULL SIGNALS but when I try to dial anything, it says Not registered on network! - WHen I went to settings... in device it is now saying:SM-903F (is that a ROM thing or is that the real phone model I have..?)
Can someone please help me.. the phone is very important here in my hosp.. cant type/read a lot of my laptop, it is very energy comsuming
Regards
P.S My location is Pakistan

See if you can enter download mode (Volume down and Power). If you can get into download mode, read off the model number displayed on screen. If you can't, the S4 is counterfeit.

The phone could also be a combination of various parts from different hardware versions of the s4.
Also, check to see if the imei is okay.

Yes bro, I can see the IMEI..
I tried flashing another ROM (TouchWiz) - Still sim is not recognized (but signal bars goes to full.. even if I take out the SIM.. guess thats a ROM issue)
Anyways, still stuck.. Which modem should I try flashing... :|

I was going to suggest a stock 9500 rom from sammobile.com but there are only ROMs for the 9500, not 9500chn.
Googling the model 9500chn links to other people that have the same problem when trying to flash another rom.

The phone model become GT-I9500CHN because of Chinese bootloader that unfortunately very hard to get rid of this stuff.
______
Your phone might be trying to connect to China Mobile or China Unicom that uses TD-SCDMA instead of WCDMA for most regions.
Also, after you install DarkLord S6 port on your device, you'll get phone model on About device as SM-G903F (Galaxy S5 Neo) instead of the normal one for more compatibility (according to the developer).
I would try to check the IMEI online to see if this is original or not (ilegally tampered from other device).

Cheap chinese fake replicas. All ib one line.
Do nothing about it. Ordering online was the worst decision.
Now there are threads here on how to manage these clones. Read one of them

I hate chinese like u do... but this is not cheap
and it is actually a REAL Samsung Galaxy
problem is its GT-i9500CHN - aargghhhhhh - pain doubling... due to me being in hospital. cant go outside to kill someone

If you flashed custom ROMs and them boot, it's not a clone. I9500 performs an Exynos CPU, Chinese clones a Mediatek one, so just for this ROMs couldn't even boot.
All you can do is try to flash a stock firmware from SamMobile, an I9500 firmware coming from China, and see what happens.
By the way, I think this guy bought a Chinese (Genuine) I9500, then rooted it for install Google Apps, that would probably be the reason of the GApps disappearing after formatting (as far as I know, Chinese phones have a backup partition where an emergency copy of the stock firmware is located, I don't know if Samsung does this as well).
For the SIM problem, it's probably simlock, and it probably works only with a determined Chinese operator (or, again, it probably doesn't supports Pakistan's signal bands).
All you can do is check your IMEI on some dedicated site and see if it's simlock, then if it's not, check if the bands that your phone supports are compatible with Pakistan ones.
Sorry for my bad english.

Again, China's bands are TD-SCDMA, not WCDMA as we use mostly over the world.

Once again, GT-I9500CHN is just from the bootloader. Installing any GT-I9500 firmware should work.

My XT1570 is recognized as XT1575 and is out of service all time.

Model: XT1570 China Dual Sim (using only 1 sim)
Carrier: China Telecom 4G
ROM: DU Official V10.6 (latest)
I have had great signals when I was on previous DU builds (Mashmallow) but the signal became unstable (completely on and off) on the latest build.
I tried changing a few options not knowing what they actually do in "Settings"->"Mobile". There was an option I can't remember but it seems I changed it from "automatic" to "home only". Since then my phone has been out of service forever. And this option has also disappeared from the "Mobile" submenu too.
I also noticed that my phone model in the info shows XT1575 instead of XT1570.
I guess I first need to make the phone to realize what model it actually is?

I flash a customized rom just to use google. So flashing back to stock is not my solution.
But I had used the DU rom for several months and all have worked well. So I think there is way to get it to work without using stock rom.

Can't you just roll back to an older version of DU and stay there until you can get the devs of DU to look at it?
In general, the Chinese models are identical to asian models, just without Google... Can't you just flash a gapps package on the stock ROM?

Identifying Yotaphone 2 model (YD206/YD201) using its hardware information

Hello
I ordered a Yotaphone 2 YD201 from china not long ago, and after recieving it I decided to check the phone's details to make sure I'd received the right version.
Unfortunately, I had received a YD206, which won't work well with 4G networks in the UK.
I contacted the seller, and he assured me that the phone I have received is in fact a YD201, stating the following:
"a few yotaphone YD201 was reflashed to YD206 before sending , pls check the phone after delivery . If your phone is YD206 system , don't worry ,it just softwareproblem , the hardware is original YD201 , we can give you reflash rom and tutorial to reflash it back to original YD201 . It will be YD201 system and work with B3/B7/B20 4G net"
My question is; is there a way I can find whether the phone was originally a YD201, or if the version I have been sent is actually just a YD206?
Attached are some screenshots containing my device's info.
Any help would be much appreciated
Thank you
- Luke

Imei = 356... -> yd201
imei = 359... -> yd206

The difference between 206 and 201 are the radio bands supported.
To flash radio only:
fastboot flash modem radio\NON-HLOS.bin
fastboot flash sbl1 radio\sbl1.mbn
fastboot flash rpm radio\rpm.mbn
fastboot flash tz radio\tz.mbn
The chinese model is compatible with 1800Mhz LTE band, that is used in some contries in Europe also,
On the phone dialer if you insert *#06# it will show the phone IMEI.
The I.M.E.I. stands for International Mobile Equipment Identity and is specific for each country,
IMEI numbers starting with 359 will be Chinese YD206, if this is your case, then you must flash the Chinese Radio even if you use other location ROM, the correct installed radio will give you better battery life and network speed.
Keep in mind that the Information on Android -> About the phone -> Model: YD201 or YD206 is not accurate because it gets its information from the ROM and not from the hardware.

Thanks for the help

Hi. I'm sitting with the same dilemma... I received the same explanation from Geeks Planet Store, word for word.
I do not even understand why they would even consider re-fashing something with a higher value (YD201) with the software that would make it look like something of lower value (YD206).
Anyway in your screenshot it says Baseband version ..._CN1_M05. Does this mean it uses the CN radio firmware?
I also downloaded their suggested firmware from the link they sent. In that there are no files under the radio folder. Does that mean the radio firmware is supposed to stay unchanged in this case? If so and if baseband _CN1_ means it is currently running CN radio firmware, does this mean the hardware is really YD206?
One more question: how reliable is the imei number check?
To me the best approach seems to be the suggestion by cvzalez to really test the radio with different firmware and see what works.

I'm confused too as to why they would re-flash a YD201 to a YD206. It doesn't make any sense.
According to this guide, the 'S01_003_3034_CN1_M05' baseband that we have is the one used by YD201s that's supposed to work with all available frequency bands. The reason for the radio folder being empty is so that flashing the phone leaves this baseband as it is.
As for the imei number, after a bit of research I've found that changing this number is relatively easy (even without root), so it's possible that Geeks Planet have just changed the imei number to make our phones seem like YD201s. However, it wouldn't make sense for them to do this and to not also flash the firmware to YD201 as well.
Have you tried flashing the phone to the YD201 using the instructions they've given you? I'm wondering whether or not to try this myself.

I might be wrong or blind, but when I look it says: "YD206 users have to change their modem components to CN version, in order to have all the available bands working. The modem version is written in "About Phone", under "baseband version". You must have the S01_003_3034_CN1_M05 version. "

I've asked the supplier if they can give me any assurance that they would help me out should I follow their flashing instructions and the phone be damaged as a result.
If they can give me this assurance, then I'll give it a go and give you the results.
Reading the comments on the youtube video Geeks Planet have sent me, it seems like this problem isn't exclusive to just Geeks Planet and is rather an issue with the main supplier of these YD201s. The comments state that both coolicool and e-fox have sold people phones with the same issue and have been linked to this same video.

The wording of this section is a little difficult to interpret. It's not really clear if baseband 'S01_003_3034_CN1_M05' is the original baseband or the international baseband.

It really looks like _RU1_ is for RU, APC, HK, EU, ME
and
_CN1_ is only for CN
(So YD206 needs _CN1_ ?)

Guys, you're lucky! You've a YD201, it doesn't matter if the firmware inside is from YD206, it can be easily changed looking at the guide you already linked.
The fact that they flashed a firmware for 206 to a 201 is because their phones are suited for Chinese market.
All you have to do is to flash the RU version (including its radio folder) and see that all LTE bands will be working as expected on a YD201!
Changing IMEI is possible, but not simple. And if your IMEI in "About phone" is the same on that written on the package of YotaPhone, you're good to go.
IMEI checking is the most reliable way to understand if it's a YD201 or YD206.

The fact that they flashed a firmware for 206 to a 201 is because their phones are suited for Chinese market.
All you have to do is to flash the RU version (including its radio folder) and see that all LTE bands will be working as expected on a YD201!
Changing IMEI is possible, but not simple. And if your IMEI in "About phone" is the same on that written on the package of YotaPhone, you're good to go.
IMEI checking is the most reliable way to understand if it's a YD201 or YD206.

Thank you for the clarification
I've been sent this reflash rom by the supplier. Would you recommend I use this or use the one on the yota website?

The one on Yota ftp site are official. I don't know if the firmware the seller sent to you is modified or they just downloaded it via ftp, repacked and sent to you. The firmware version is invisible looking at the files, first you have to flash it and them you will see which version it is.
Personally I would flash only official firmwares.

Ok, I've decided to try and flash using one of the official firmwares.
If I were to flash to one of the RU firmwares, which one of them would I need to use?

In this guide this information is already written down, anyway use the latest which is: 5.0.0-RU1.1.124.zip.
Let us know which version of firmware and baseband is the ROM the seller provided you!

Did it work? Could you test the LTE capabilities with the RU base band?

I've managed to flash the phone using the firmware the seller provided. I have also managed to install an OTA update.
I've attached a screenshot with the new device details.
Is this the correct version that I should be on now?

At least the baseband changed... which I guess is a good sign. For me now the big question is: Does LTE B20 work? (That is what I need where I live.)
