Problem on cellular network - Lenovo ZUK Z2 (Plus) Questions & Answers

I have a problem with the phone reception. I installed the various versions of Zוk 2 and all of them have a problem of absorption except for Chinese rםm. I thought of flipping the Chinese modem. Does anyone know how to do this? I'm not an expert.

Is anyone else having signal issues? Possible baseband update?

I recently purchased a samsung captivate glide and I have noticed very spotty coverage and dropped cell connections. Whenever I am indoors I cannot get a signal. The cell reception is very sensitive and constantly shows no connection. I was unsure if anyone else was having this problem?
I found another thread that had a loose sim card issue and attempted the fix but this did not work. I've also tried my sim in another phone in which i had no problem with cell reception. I've relashed the ROM and Kernal multiple times, rooted, unrooted, nothing seems to fix my reception issue... I was not sure i there was a baseband update or I just have faulty hardware. I'm eager to get this phone working at full capacity. How can I get it working properly?
Pertinent Info:
Android Version 2.3.5
Basband Version I927UCKI3
Kernal Version 2.6.36.3
Build Number GINGERBREAD.UCKI3
Carrier AT&T
Thanks in advance.

Sounds like status quo for AT&T
On a serious note; I am not having any such issues here in southern Louisiana where I usually don't get anything but Extended; rarely ever see 3G.
Been looking around for more information. I'm going to try and get a new sim and see what happens. Looks like i'm stuck for the time being :/

Try pulling the battery cover and see if your SIM card is loose? I've advised for a couple different folks having signal issues the same thing, nobody else seems to have the same problem I did - using a smartphone SIM, it looked like the metal cage for the SIM card was a millimeter too large in width and height, I used some strong clear tape to hold the SIM in place and havent had any issues since...
HTH!

//Edit - I need to read the _ENTIRE_ post before replying - sorry, I'm fresh out of ideas if the loose SIM card wasn't the problem :\ -tidE\\
Ok I take no credit for this, but felt bad about the useless post above, crawled a couple more posts this morning, and it looks like mariol66 may have found another solution -

Japan Docomo Note 2 No reception No service

Got a Japan version note 2 SC-02e, after flashing MIUI rom, everything works fine except the phone function. There is no data, no signal, no reception whatsoever. I tried to manually search the service operator, but it turns out nothing. I suspect it may be a problem caused by its unique band. I appreciated any fix suggestion.:laugh:
you might have accidentally unknowingly regretfully ****ed up your imei i.e. ****ed phone features.
before regretting try restoring nand/stock firmware etc.
if you made a backup of your efs then there shouldn't be much to worry.
if not and restoring stock doesn't work, then go to a service center and convince them that you are a innocent cute little guy whose phone was ****ed up in the morning.
Good Luck
Most common mistake for most people or noobs is that they did not know what they are
doing with their devices. Most probably you have screwed your EFS folder.

you have to do it the hard way.

I hope this isn't too late to help you but are you running the SC-02E in Japan, and if so are you using Docomo or are you trying to use it on a different network?
I've experienced similar problems in the past and in my case the cause there were two separate causes. First of all Docomo Xi phones sometimes have issues when trying to connect to a non-LTE network (such as with B-mobile or softbank) yet often have had the menu options for turning off LTE removed. I had a similar issue when I used my SC-06D with a 3G B-mobile sim (which uses the same 3G network as Docomo) and at first I had the issue of not getting any connection. However after I used a 3rd party app to disable LTE (LTEOnOff) I was able to connect without any issues.
The other cause may be as you said from the unique bandwidths. Japan's LTE network is different from other countries, and traditionally the only common 3G bandwidth used in Japan that is used in other countries often is the 2100mhz one (although Softbank did recently implement 900). Therefore if you managed to flash a ROM for one of the overseas N7105's then it's quite possible your phone is having trouble due to the LTE bandwidths. You could try disabling LTE (as above) and then seeing if your phone connects via the 2100 bandwidth. If that works then then you will probably need to try flashing a Japanese radio (from the SC-02E) to get it to work. This is something that I am trying to get working myself.
For the record Docomo's network runs on 2100/1700/800 for 3G (although 1700 seems to be rarely used) and 2100/1500 and possibly 850 for LTE. Softbank has 2100/900 for 3G and 2100 for LTE. AU runs on CDMA and CDMA2000 technology and thus their network isn't compatible with Docomo's phones.

Unexplained weak signal and poor reception on an unlocked i317m, please help!

Hi all, this is my first time posting in these forums.
I've recently purchased a used rogers model i317m galaxy note 2 and used the dialer code so I could use it on Telus.
Since doing so, I have experienced intermittent, unexplainable signal drops, especially going into indoor areas. I have a friend with the same model phone, but Telus stock, and we have compared signal strength over the last two weeks. In a friends basement, he gets full reception on his note 2, while I get nothing.
In dealing with this issue, I have perused these forums for weeks. A variety of threads in the various note 2 forums all point to something fishy going on with galaxy note 2's that have been unlocked with the dialer code, and no conclusive evidence or answers regarding what the problem is, or how it can be fixed. It seems like those threads simply die because people cannot provide an explanation.
I have taken the phone to multiple repair shops, but their answers were all varying and they were more interested in trying to sell me on replacing the main board for $300 than helping me (no idea if it would actually fix anything if it's software related). I originally thought it could be a hardware antenna issue, but looking online and inquiring at the shops, antenna problems are so rare they don't even have stock, and have never been asked to replace one.
I doubt it's a hardware problem, and the other loose threads regarding this issue seem to confirm that it is software related, and only happens to dialer unlocked note 2's. And since I am getting reception (3bars and let outside, 1 bar and no data inside), the antennas do seem to be working.
ive tried a variety of solutions suggested on* the forums, but to no avail.
1) factory reset, no results
2) new sim card, no results
3) flashing a stock Telus rom, changing csc code, nothing
4) flashing new telus radio (even though I know rogers, Telus, sasktel all use the same radio), nothing
5) flashing aws band, made reception worse (maybe)
6) using *#*#2236# code, changing options, nothing
7) calling Telus, explaining the situation, having them make sure everything was fine on their side. Everything checked out and the Telus guy was equally confused by the problem.
8) main Samsung tech support, same issue. The representative was confused as well, and started cruising xda to try to help me!
This has been incredibly frustrating. The signal drop is so bad it basically renders the phone unusable. Right now I'm sitting in a house on the main floor on wifi next to big windows, and I'm getting one bar of reception and no data at all. On my nexus in the same room I was getting full signal.
The only thing I haven't tried is flashing modded baseband radios, but another person with the same problem on xda tried that and it didn't work for them at all.
I think I'm out of options. Planning on selling it to a used store for cheap and buying one fresh from Telus, or ordering an international model so this won't happen again.
Can anyone help?
Thanks so much.

I had the same problem, reset flash counter to zero and returned it to Samsung for warranty. They fixed it for me. I am on my phone now so i can't link to the thread, but if you Google reset flash counter to zero gn2 xda, you should find the answer. Hope this helps.

Thanks. Was it confirmed to be a hardware problem? Will they accept used phones under warranty?

Try flashing this rom and flash your modem/radio before you reboot system. I am using it right now and my signal increased with this stock rom. I am using Ma3 modem with it and works great.

Yes, they told me it hard ware, and yes, it was used and still under warranty. Try contacting Samsung through online chat via their help center.

It's a hidden menu, that's within the phone. Same way you unlock it by using the hidden menu!

I was having the same problem on my Note 2 i317 and seem to have fixed it with the latest modem i317UCAMH3. It still fluxuates, but now I get a full 5 bars of reception and it lasts much longer. I also downloaded an app call OpenSignal, that seems to help...cannot image exactly why, but when I get low reception, I open this app and watch it jump to at least 2 bars and then I can make a call again (this was before flashing the newer modem), now I just use the app for visual purposes, as the Beanstalk image for reception is hard to see, OpenSignal has nice big green bars that are easy to see. Try the new modem and give it at least 15 minutes to connect, then it seems to stay connected for me...except when it locks and goes to sleep...it still loses reception when that happens, but that is an issue for another day.
Cheers!

[Q] Network issues with SGH-T999

Hello there , I hope everyone is enjoying their holidays..
Need help , i have sgh-t999 which came from USA, its unlocked but i have signals issues, whenever i enter my home, the signals are gone, but signals are fine when I'm outdoor. I have tried flashing different modems from doc's thread , but the problem is still there. I m running on the ENC2 firmware, which is the latest one. I have also tried to change different carriers.
I think sgh-t999 antenna is not strong enough to catch signals in congested areas. Tell me your thoughts , or suggest me something.

Problem with IMEI and signal

Hello I bought an used ATT Note4 unlocked and I use it with TMobile. I have two problems maybe related. I have very low signal and the phone dont connect in my home and my previous phones didnt have that problem. In works in other places but you know it disconnects inside buildings and low signal areas. I was thinking in flash a TMobile modem and I think its not possible. The other problem is the IMEi that shows in settings is not the same as the sticker behind the battery so something has be done to the phone. Its possible to fix the IMEI to the real one?
Thanks a lot.
It might be a fake, install cpu z and compare the hardware results to a real one
