Hi guys, i am new to android phones and i have a i9000 but i have 2 problems. First, although my signal appears to be full ( 3-4 bars ), sometimes i can't hear another person on the phone, or that person can't hear me...it's like i'm having bad reception. The second problem is that sometimes when somebody calls me, the phone doesn't ring and doesn't turn up...nothing happens, i don't even know that i was called.
Firmware version 2.3.4
Baseband XXJVR
Kernel 2.6.35.7-I9000-CL425308
Thanks.
anyone?
Is the phone still stock, and under warrenty?
If so take it back for repair
No, it's not stock, but i belive i have a backup somewhere... if i can't send it to warranty what should i do?
nobody?

If you don't have a backup, flash a stock rom with Odin.
Already tried different modems?
No, i didn't try any modems, that's why i've asked you guys, which modem should i try to improve the signal but also to have good battery life. Thanks

You have to try cause a modem that works for me maybe is not good for you. Good luck
Ok. Here is another question: if i put a different modem, will affect it the battery life? Or the battery life is connected to the kernel version?
From what I understand, changing modems does affect battery life in terms of searching for signal. As people stated earlier, you're going to have to try different modems to find the one that provides you with both the best signal and the best battery drain. If you live in a country where many people use the SGS and you use a popular carrier, it is possible for you to determine which modem is most likely going to work out well for you. Just run a search with your carrier, model number, etc.
Are the compatibility issues between modems and kernels? Can i try any modem with my kernel?
someone?
Firstly you need to eliminate, if its a carrier issue or phone. you can try a different sim card. or try your sim in another phone...
Also what is your signal in -Db (you can see this in phone status).
Another thing you appear to be on a very old ROM, try flashing to the latest official Samsung Rom.
if all this fails then it looks like hardware issue. You could try using headphones to eliminate if the speaker and mic issue.
just think logically...I'm sure it can be fixed.
Ok...first, it's not a carrier issue because my girlfried is using the same carrier and has no problems. Second the signal strength is "-75 dBm 19 asu", but like I said, the signal appears to be full when the phone conversation is stating to have problems and I'm not walking when I'm on the phone ( the signal can not be lost by changing the place from where the phone is used )...I have 3 or 4 bars all the time...so I don't think it's a hardware problem because if it were I shouldn't be able to have good signal at all, but I do. That problem doesn't always appear.
I know that I should change the modem but I don't want to decrease the battery life. So, my questions are:
1. If I change the modem will the battery life be affected? If yes, what is the best modem for battery lifetime? If no, it is deppending on kernel:
2. Are there compatibility issues between modems and kernels?
Thanks!
the modem changes depending on the area where you are and the operators.
In italy i use i9000xxjvu and this modem work very well and consumes very little battery
Yes different modem firmware will affect the battery performance.. some are better than others..... why don't you take a nandroid backup of your current rom...and test a complete new rom with latest modem firmware..just install a stock official latest rom for test purpose. If it still bad , you can easily restore from the backup But I think if your signal - 75 DB (which is like excellent) and your having problems hearing ' speaking ... then it looks like speaker ,mic.. use your supplied headphone to answer calls..as another test , to see how it responds
if you hve stock non rooted firmwre from your carrier or for your country it is plain stupid to play with modems. samsung knows how to fit proper modem for particular region.
parameters you presented also indicates that there is nothing wrong with modem<->bts communication, signal is more than decent.
this might be a problem with some application or some previously installed application that messed up with phone.
i would advise:
- backup of any data you will need
- backup of apps
- MAKE FACTORY RESET from recovery menu or via dialpad code
- retore APP ONLY and USER APP NOT SYSTEM APP
- do not restore app data, or retore app data one by one checking if that affects your phone
if that wont hellp, youre clear to send your phone to samsung repair center

Hi I am in fringe area reception. Find that this ROM seems to lock its AGC high eg after reasonable signal, then reduced, it seems to sometimes lose signal altogether, needing a reboot. Yesterday even in a strong signal area, and reboot a few times it took 3 reboots until the radio came 'unstuck' and started to receive again.
Question is for WM6, is there a radio rom that is more reliable than this one?
If so, url pse.
Thanks vm.
Alistair.
All U can do is to test also 1.13 version. There is also possibility of faulty GSM module.

I had problems with the radio that were caused by the old battery.
replacing a new battery, fixed many of my BA's strange problems.
If your BA's battery is old, too, then give it a shot by changing it.
True True, i had some weird problems which were solved by purchasing new battery

Can understand that, because the power saving mode would lock down on radio activity, however, the battery in this unit lasts at least 3 days, and the problem occurs regardless of battery level; eg it can be on the charger when it loses signal.
Why I asked is there was a thread a while back on various radio problems and I thought some indicated a different rom was the cure. Unfortunately, could not find the thread or url for the radio roms.
Cheers,
Alistair.
yep, i used to experience faulty battery stuffed up the radio big time.
Dain your battery completely.
I was having the same issues on my BA, so that when i dropped it (5" onto a desk) and cracked the digitizer, i went out and purchased an elfin.
But i couldn't abandon my BA, so i fitted a new digitizer last night, recharged the battery which was completely drained, installed a new rom "Black Diamond Manila2D", then loaded my sim card, i had signal straight away, where i was getting none at all. I would have to drive 5 K's away from where i live to be able to get the phone to "lock on" once it lost signal, so it was a bit of a shock.
Anyway give it a go and see if it works for you.
I usually get "no signal" when I restore "pim.vol" from previous rom, it resolves when I change the above file with original one.
I did try different radio versions with same result.
pls check if this is not your case as well.
I m on fido network in canada, and 1.13 work better according to my exprience.

which radio version are you using (and also which 6.5 rom)?
Hello,
I've been flashing for a long time and currently I'm running Bionix 1.2. I've got 2 major problems and I have a workaround for each; however I thought the community might know better than me.
The first one is about the signal bars and dropped calls. I live in an area (Maine) where you never experience a dropped call since there aren't many people living. At least with my old MyTouch and stock Vibrant, I never had one. So almost once a day I drop call and see the all the signals gone. Sometimes, I see signals but there is no data or GSM connection since I cannot login to GTalk and other services (FB, twitter, etc.). I read in the development section that turning flight mode on/off can help. Well for me, it sometimes helps, sometimes doesn't. I find myself rebooting to solve the problem at least. I am a little concerned since I might need my cell in case of an emergency and I definitely would not want to wait for a reboot to call 911.
The second one is about the GPS. If I open navigation and ask for turn-by-turn directions, almost every time, it gets stuck searching for GPS. The workaround for me is to launch Maps, wait a few minutes to locate my location; then ask for directions. Although, this might not work from time to time. Again, in the middle of nowhere, you are driving and need a quick and dirty turn-by-turn directions and your smart Vibrant makes you go thru a lot of hassle to accomplish your task.
Any advice from our community?
Thank you!
Flash to stock, call t mobile and tell them your gps is non functional even after the froyo update, and get an exchange. My gps works INSTANTLY. Cold. I type my destination in Navigation and when I press enter my navigation is already talking. No maps, no 10 minutes, no downloads, we all know these are often placebos and we are still waiting and waiting for a signal which can still go off road randomly, etc. none of that with a new phone.
I did not try the physical gps fix in the forums but that could work too. Your gps still not be fixed by software, its a hardware problem. It seems phones manufactured after October (?) do not have the gps issue. Worth the hassle for me, at no cost if you do it for the gps issues and there is no physical damage to your phone. Just make sure you flash back to stock before you call because they will ask you to go through your system information on the line. Back up EVERYTHING and put it on a computer, get your exchange and flash back to your favorite rom and enjoy your now fully functional Vibrant that works in every way you bought it to work. And make sure you not only factory reset before you send the old one in, but also delete anything incriminating on your internal sd because a factory reset won't do it.

Don't blame the rom...Your hardware sucks.
Been running TW roms since the Bionix 1.0 days and NEVER had any issues.
Those problems are not inherent to TW roms, it's a problem with the phone.
@TheSneakerWhore, @deadpass:
OK - it might the hardware, but how do you explain no dropping calls on stock 2.1? I've used on stock for at least couple months and never had to reboot my phone because it did not have signals (or had signals but no connection).
I also flash Axura roms and never have a similar issue but they are too customized for me.
PS: I am not trying to blame the TW roms specifically nor am I defending another rom. Actually, if you open the latest Development thread, you will see my post thanking those guys because of an excellent job they've done. I am just not happy with the data and GPS - which I never had an issue before starting flashing TW and thinking others might be experiencing the same.
Strangely my GPS and cell signals seem stronger on TW ROMs than most others... It might be just slightly different hardware (not all units are created 100% equal after all) reacting differently to the software?
Have you perhaps tried Trigger v1.5? I thought the theming was very tasteful, you may like it, and it seemed pretty solid on GPS and signals.
Thanks, @Oxirane. I will give it a try.
I would try out different modems. For instance jl5 and kb1 great with gps in my case. jfd, ji6, ka5-7 all were teh suck when it came to gps. It all depends on your phone and location too. So flash away and find whats right for you.

I lol'd @ this "I live in an area (Maine) where you never experience a dropped call since there aren't many people living."
I'm with the OP on the drop call and inconsistent data issue. By all means, I have flashed almost every ROM out there. Every single ROM on here is awesome and all respects to the devs. I'm currently on Bionix 1.2 now for the third time and what I have and still noticed is the inconsistent data drop 2-3 times a day. No biggie since I managed to turn airplane off and back on and everything's back to normal. At first I thought it was KB1 that's causing this so I decided to try out different modems/kernals. After playing around a bit, I decided to stay with KA6 for a few days and noticed data improvement but still inconsistent (loss data connection). I also flashed the ROMs (Axura and Einherjar) and I don't have the data loss. I also flashed all the way back to Nero 5 just to check it out. I do not have any data problems with Nero 5. Anyways, I don't really mind every now and then switching air plane mode off/on. However, the issue as mentioned by OP does exist on some phones.
I'm running Bionix V 1.2, and the last 4 ROM's before this were all also TW ROMs.
I have not experienced a single one of your issues. My phone is fast, smooth, and have excellent signal and data everywhere around my area.
I doubt it is the ROM, but I'm no expert and cant say that for a definite.
But if myself along as many others , including a few buddies of mine, don't see those issues it just seems unlikely to be the ROM.
But who knows....
Well im guessing its the change of modems that's causing your issues... im sure it has nothing to do with the rom espeically since you never had issues supposedly when using Axura (since axura is based on bionix). Almost all the roms on here are based on TW roms, just change modems, theme, add a few random options, from what i've seen in the code. Like other suggested tryin flashing different modems and find the one that works best for your area. I've been running Bionix V 1.2 since day one and have not experienced any of the issues you have describbed...

I know your not trying to act up or anything, but thats kind of just mean.
I mean these devs are helping us by giving us more options.
Most of them aren't based on TW.
some are, most aren't.
but your saying "almost all the rom on here are based on TW Roms, just change modems, theme, add a few random options"
I'd like to see YOU edit the modem and theme and add a few random options and make a ROM. go ahead.
I can say that TW is also just editing a few codes and theming on a ROM that Samsung made, and that they aren't developers.
TW set a standard, a precedent, and people will follow it, but they aren't copying it.
not complaining at all to any ROMs. just throwing out my input to let the OP knows that he's not alone in this world. To me, if there's a way around the problem, the problem is minor. Besides, I flashed and used different ROMs like changing diapers. LOL. I like to keep my Vibrant looked different every 2-3 wks. Pretty soon, we'll see a flow of new ROMs and I be all over every single one of them like "flies on sh!t". Dang, haven't used that expression in a long time. LOL

there is not "editing of modems" its changing modems... and theming is nothing more then changing pngs and .9s and edit xmls... its not very difficult... time consuming but not difficult. as far as what TW does to their roms in decompiling smalis and editing the Java, i've personally only seen a handful tru developers here actually doing it to what samsung has leaked. MOST of these so called roms have taken the edits that TW has done and just dropped their own changes on top of them. This has been proven time and time again! but regardless you are entitled to youre own opinions.
My point is that Axura IS based on TW's edit so if the issues persist in TW rom but not in Axura, one of the causes would most likely be due to the modem cuz im 99% sure that several Axura roms use different modems.... that is all i was trying to say.
One thing I have not seen in any of the posts that are having the issue is what modem you are using.
I will say it now, KB1 modem sucks monkey balls. I haven't had any dropped calls on it, but have stale connections all the time. What I mean by that is, my phone is sending data packets, but isn't receiving any for a good 30 seconds.
So, try a different modem. KA5 seems to be the best modem for signal and battery life.

THX Krylon360. To be perfectly honest, I tried different ROMs and modems and noticed some significant improvements. I totally agree that KA5 and KA6 are better for me in terms of signal hence KA6 is what I stick with as mentioned in my previous response.
surprisingly, these problems can come up from odd combos of apps or some configuration that is unique........ Lucky you
I had some phone disconnects on my phone when it was on a TW and Eugene kernel, but it was a custom mms I installed that caused the issue..... so you might look at what you got on your phone as well. Remember, some of the app developers did not or do not update their apps and this may cause an issue especially running a 2.2 platform (especially a ported 2.2 platform) if they are older apps. Food for thought
I was having the same issues with 1.2. dropped calls, no data, constantly switching from edge to 3g, etc. had no issues with nero. As everyone said, try a different modem. Worked for me.

Thanks everyone! krylon360, I should have mentioned the modem I've been using: KA5. So, it's weird how you and some others find KA5 and KA6 to work best and I had all these problems with it. Maybe it really is a unique combination of apps, configuration etc.
Last night I flashed KB1 and will give it a try for a few days. I tried GPS on my way to home; opened Navigation and entered directions, and I got instant lock. I see that as an improvement. Will follow closely. Thanks again!

There's nothing wrong with the roms i been flashing since i got my vibrant once flashing do you wait the initial 10 mins and then reboot before you start using your phone? if not you may want to try that. TW roms are pretty much flawless.
Hello,
Im having a most frustrating problem. Im not sure if its a modem issue or a hardware issue. What I am experiencing is this:
The phone shows no bars, but sees a carrier. This happened after flashing back to a stock GB rom after using a CM9 rom. I can receive texts and calls sometimes, but its not consistant. If it shows no bars I can get a call, if it shows one or two bars i cant, but get the missed call notification. I have done factory resets, cache clears. Its really making my phone unusable. I went back to using my 3 yr old Ericsson till I can get this figured out. Im hoping that someone has some advice for me as Im out of ideas. Ive tried to flash just the modem but no luck. Went from CyanTablet to xxjvt 2.3.5, rooted it so I could get the modded recovery. The pins for the where the sim card make contact are damaged but it has worked for the last 2 months that way. I really love this phone and dont want to replace it yet.

test with a network booster to increase signal strength, free from google but if you bring phone to another location, do you get a better signal? meaning location matters, if you far from your network cell site, its more difficult
Ill try the network booster. All of my old phones pick up 5 bars, I live about 1/4 mile from the cell tower. I have tried another flash with 2.3.3, repartitioned this time. Once its back up and running Ill get back to you. Is there anything else Im missing? Well I think its dead. Ive tried all my coworkers sims in it, nothing came up. It says no service permanently now, guess its a 4" tablet.
Try another radio, i had the same problem wit JW4 radio,flashed JVT and problem solved.
Some radios are better than others in different locations, it also depends on rom used.
I tried a completely new build, flashed a new modem, then flashed xxjvu. Still nothing, going to call Samsung and see if I can get the warranty to fix it. 2.3.6 tho has 364 megs of ram and has almost 200 free, thats cool. zsjw4 has a new look to it.
Hi,
I have seen some posts here with lost cell connectivity. However my issue is slightly different and started to appear few weeks back. I was rooted running stock 7.1.1 OS with Franco kernel. My phone started to loose signal all the time. You can just look at the signal bar and see the signal strength going all the way from 100% to 0% in every few seconds. I have tried different radio versions, new ROMs, restoring my Nandroid backup etc. Nothing seems to work. Changing to 3g shows the same issue and I have no signal on 2g only mode. I am in AT&T.
Also wanted to add that I can make out going calls from my phone. The issue is when its idle. I don't get any incoming calls due to this issue.
Any help will be highly appreciated. Currently using my office iPhone and feels terrible.

I'd run up to AT&T and ask for a new SIM. It's free and you rule out something on their end, and the SIM too when they provision it. Is your phone carrier (SIM) locked to AT&T? If so, I'd see about getting it unlocked so you can test other carriers. If already carrier unlocked have you tried borrowing a friends SIM on another network? If signal continues to drop it could be a hardware issue.

You sound proficient enough with flashing ROMS, radios, restoring Nandroids to know this already.... you are probably just postponing the inevitable: Back up and pull off all your data, format the partitions, and flash the latest full factory image from your PC using flash-all.bat. You will have your answer very quickly- in fact you will know even before you begin to set up your phone. If you are still under warranty this will be step number one with Google or Huawei.

Hi all,
I have an N910G in Australia. I have tried many different roms and different OS versions but always have the same problem of random shutdowns on low cell signal.
I'm currently running the Andycar rom because it's just a customised stock MM room and even uses the original CSC.
My phone has never been better but the random shutdowns are happening even on this room.
It can't be an EMMC issue because the phone is perfectly reliable on a stock factory rom.
My wife also has an N910G. I have the exact same issue on both device.
I just installed wakelock to see if it helps but it's too soon to know yet.
What am i missing?
Thanks in advance for any comments
Battery. There is a topic about it out there somewhere.
Only with non standard roms? Multiple phones and batteries, all working properly with stock roms, all will work for days with a reliable cell signal. All will reboot or turn off with a low or changing cell signal.
I'm not ruling battery out but it doesn't sound right to me.
My gut feeling is that it's CSC or BL related but I've tried original stock versions with the custom ROMs - same problems.
The last rom I tried was a customised debloated stock rom - same problem.
I'm lost ...

Hi all,
I have stared from scratch with another fresh install of Andycar customised stock MM 6.0.1 rom. I can use it around the house perfectly for days on end. Battery life and performance is awesome but when I go to work the phone will randomly shutdown every 10 minutes or so.
It's definitely not battery.
It's not EMC.
It's not the sim.
I've flashed modem.bin and NON-HLOS.bin from the stock rom (that works 100% reliably) but still I have the same problem that I've had with every single rom I've ever run apart from the stock Samsung rom.
Any time I go somewhere where signal is low the phone will soon shutdown instantly.
Is there anyone else in Australia running an SM-N910G on Telstra with a non standard rom?
Hi, I am not in australia, but can say this.... for what its worth, I have an n910v galaxy note 4 on a custom rom myself. I have set up 3 others exactly like mine. I have not used the rom you mentioned but am using the modestrom instead. none of the phones I set up have ever had random shutdowns. It may be a random problem with the rom itself. I know it isn't really helpful, but wanted to state it anyway.

Hey tattmann,
It doesn't specifically help me but I do appreciate the reply :good:
It's strange that i can produce the same problem on multiple (3) devices with so many different roms. I can't believe that no one else has had the same problems.
In every case I can restore a stock rom and the device will perform reliably - despite having horrible battery life, masses of bloatware and crappy performance...
Thanks again for the reply
With custom roms my phone is shutting down completely when i either open gallery or do two or multiple things at once. Weird thing is once its shut down i cant power it on immediately. I have to connect to charger or remove battery. Then its turning on when i press the button. Sometimes it happens irritatingly fast.
