[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.
hi guys im a new android user. i bought my i9505 galaxy s4 3 weeks ago and everything is working perfectly except the mobile data. i can only connect to E/G signals with it (which doesnt really do anything because i cant even check emails). its on LTE/3G/WCDMA/GSM(automatically) setting and the APN is the correct settings with the carrier in my country(philippines). i tried my sim on a different i9505 phone and it was able to connect to 4g so i guess the carrier/sim being the problem is ruled out. i have restored to factory settings/rebooted multiple times and am still unsuccessful. the phone's IMEI is not blacklisted or banned and it is intact(dont really know what that means but it shows a long series of numbers and im not really sure its safe to post it here). My carrier also supports the frequencies listed on what the phone has. i have not installed any custom firmwares and have not re installed any official releases.
i would really appreciate it if someone can help me fix this problem. could it be a software problem or a hardware problem(praying it isn't)?
my phone specs are
GT-i9505 samsung galaxy s4
android version:4.3
baseband:i9505XXUEMJ7

Hi there,
I've been looking around this forum for more informations but was not able to find the exact answer, so here i am.
I'am using Galaxy S4 I9505 LTE ROOT, Honk Kong release:
Kitkat 4.4.2
PDA: I9505ZHUFNB3
CSC: I9505ZZHFNB3
MODEM: I9505ZHUFNB3
IMEI: FINE
My issue is unstable mobile network.
Sometimes working well, then unable to find any network for a day or fast reconnect using the connexion pannel.
I've been looking for threads about modem issues and i've found plenty of version but no one for this model in china (it's not sell in china) , it seems that i have the latest one for HongKong.
Is it possible to install another modem on my phone and do you have any idea which one is better for China mobile network and will also be able to work In the rest of the world.
I also need this version not to break my wifi or my sound cause i heard it might be possible with some realease.
Ressources i've been reading:
[REF]GALAXY S4 (I9500/I9505) GSM / NON-HLOS - MODEM'S Collection (Odin/CWM/TWRP)
GALAXY S4 (I9500/I9505) GSM / NON-HLOS - MODEM'S Collection Odin/CWM/TWRP)Post 2549(

Same for me with my sm-n910w8 in videotron - canada .... option lte not work stable ....
sounds weirdly
i flashed this, maybe it's due the ROM
PDA: N910FXXU1ANJ4
CSC: N910FTTR1ANJ3
MODEM: N910FXXU1ANJ4
i would like to try other ROM but does flashing stock to stock via ODIN wipe user data?
Hi All, nice to meet you all here. I came from Malaysia and i facing some problem with my N9005 - Samsung Note 3 LTE and hopefully can get some helps from here. It was actually a second hand phone but with perfect exterior condition, with Samsung warranty seal to prove that never been repair before or a recon phone. Below are the problem that i realize within this few days
1. Phone have signal, but sometime unable to call in or call out, especially on low battery status (50%-30%)
2. During a phone call, receiving party always unable to hear me, sometime they will hear some strange sound and dropped call, but from my side I can hear them very clearly
3. Always changing network mode. For example 4G to HSPA+ to HSPA to EDGE to No Service
4. When phone was inside a indoor room, very poor signal & unstable, internet speed also very slow or even unable to connect. But when I walk out from the room its become better
Remark:
1. Using Lollipop 5.0
2. Have changed a brand new Sim Card
3. Have tried to move my sim card to other phone, work perfectly
4. Have tried to use other sim card, but same problem remain

I don't need IMEI atm. Well the problem here is that the person who owned the device before you, flashed a Philippines (Globe) firmware on your device. You have weak signal, weird sound, etc for that reason.
Your phone is original unlocked of Malaysia (XME) but still without Lollipop firmware. You can check it: HERE.
* SOLUTION: All zones close yours (Philippines, Thailand, etc) still without Lollipop update. You will void your warranty if you downgrade your device to android 4.4.2. Here we go:
1. I recommend you flash the Slovakia (TMS) firmware via ODIN then coz it has the Lollipop update (like in pic attached). This won't void your warranty either.
2. Dial *#1234# when the process of flash finish and have to appear this. Reflash the same firmware if not:
AP: N9005XXUGBOD6
CP: ?
CSC: N9005TMSGBOE1
3. Wait latest firmware updates of Malaysia (XME) and flash them via ODIN for receive future OTA updates too.
Hi Joku1981, thanks so much for your reply. Since the phone was actually out of warranty period, so i tried to flash back with Malaysia (XME) version of 4.4.2 kitkat (PDA: N9005XXUGNI4, CSC: N9005OLBGNL1).
But unfortunately, the result still the same. Am i missed any important step?

leutzu, i has been tried to flash a few times with new firmware but it's still remain the same problem. I have also sent it to Samsung dealer for checking and they said probably on hardware problem. So end up to save up my time and cost, i decided to bought a new Note4 SM-N910C.
I end up sending it to Samsung, and they replaced motherboard, battery, and updated the soft.
Now it's working fine
