Well I have scoured over all of the D2G forums and can't seem to find any information on replacing the signal bars in the phone with dBm, which is very irritating as the bars themselves don't seem to correspond to a specific number, at least not on my phone. I know CM6/7 built this feature in, would it be at all possible for another rom to build this in as well? or would that require modifications that the locked bootloader doesn't allow? Or is there a rom for the D2G that can do this and I just missed it or something? Any help would be greatly appreciated.

After much reading, and stumbling over the same posts repeatedly, I must ask for help.
Heres the phone:
Gt-i9100
2.3.6
i9100NEKF2
2.6.35.7-i9100XWKK5-CL754841 [email protected] #2
Checkrom RevoHD V4
CriskeloROM Gingerbreak v32
Currently have a Optus sim loaded into it, staying in Melbourne Australia.
Optus seems to be lousy, I've talked to several people who seem to agree. Since public perception is far from accurate, I cant really blame optus entirely. I havent tried any other SIM cards yet since I need the optus number at the moment.
I've tried quite a few ROMS and quite a few different Kernels, not being able to tell much of a difference in signal strength. The phone will have the 3g icon lit up, but refuse to do almost any activity. Then five minutes later in the same location it is working perfectly, with a ping of 147ms and download rate of 327.7kB/s (using Speedtest.net)
Since I am using KitchenPro I am able to change the modem easily, some dont work, others do. How do I narrow down which ones are best for the phone? The answer of "use it for a little while and you'll know" cant be the best answer. Is the carrier-shipped modem the best that is available? I've read the modem ref guide and it doesnt offer anything other than a list of letters and numbers. Some people have reported things working well with telstra on particular modems, but nothing on Optus.
1) Is a baseband or modem something that will either work, or not work? Or there a signal difference from one to the next.
2) I almost always have 3+ bars of connectivity for the cell service, it works fine, all the time, even with the modems that did not allow data connectivity the phone always seems to work. Does a modem package effect both cell service and data?
3) What would be the most effective method of testing a new modem?
4) Is there a guide somewhere that lists the guts behind the modem packages, ie frequency ranges, so that I can look up the carrier, and match it manually with a modem?
Please Help! With spotty services available, and no means of telling if my problems are carrier related or phone software issues, I find this quite frustrating.
Thanks for reading
I have one of the original GS3's that came with the 'No Sim' error from the factory. I have since installed CM10.1 and now instead of the error the phone just reboots. It works fine on certain towers but there are some Verizon towers I get close to and I cant place a call or text without the phone rebooting. Is there a different kernel or anything that someone knows of that I can flash to help this? I am getting tired of only being able to use my phone in certain parts of town. I have ran several versions of CM10 with the same results. Currently on CM10.1 RC4. Thanks

1. Kernels don't have anything to with the radio signal the modem however does .
2. I have mentioned this to others that your location and how well designed the radio is determines how good or bad is your signal strength.
3. You can flash different modems to see if that will help and here it is:http://goo.im/devs/invisiblek/i535/modems

Thanks for the response. Was the original NO SIM issue due to the modem? Also, are there any of the modems on that list that are preferred over others?

I honestly don't know as I got this phone 4 months after its release so that issue was resolved by then. Like I said in my previous post that your location and how well built the radio is determines the overall signal strength so the modem might not help. I live in New York City so I don't experience bad signal strength in most areas in the city. In the end you have to try for yourself as someone living one area won't likely to have the same results as you.
Hi everyone.
I owned a Nexus 5 one month ago, but unfortunately, it does not work as expected. On 4.4.0, I had multiple issues concerning network already (unable to switch to 3G networks only, very variable HSPA signal reception (from 4/4 bars to Edge exactly at the same place), ...). This issues were supposed to be fixed with 4.4.2 and most of them are, excepting HSPA signal which is still very weird. However 4.2.2 brings my phone another issue that I didn't noticed on 4.4.0 which is a very annoying and repetitive complete signal blackout (no reception at all (Edge/HSPA), even for emergency calls I guess). Signal drop can happen twice in an hour, twice in 10 minutes or may not happen at all 3-4-5 hours long. It's completely unpredictable. After a while, Edge signal (not HSPA !!) gets back by itself. If I wait 10-20 more minutes, HSPA comes back again, until it drops again.
Moreover, at phone boot, just after typing my PIN Code, it usually takes 2 or 3 minutes to catch a signal. Very slow isn't it ?
It does not seem to be a network issue, since my Samsung Galaxy S III doesn't encounter this using the same SIM card.
I read on Google forums and probably some XDA threads that I was not the only one to face this kind of network issues, even on 4.4.2, but issue description was each time a bit different from mine, thus I tought that it may be useful to post a new thread to describe precisely what was my problem.
Edit : My Nexus 5 is unlocked and rooted, but issue is present on untouched 4.2.2 also.
Edit 2 : http://forum.xda-developers.com/showthread.php?t=2525583 is probably my issue.
Do no hesitate to answer if you're thinking that you have the same issue (or kind of) or if you think that you know something that may help.
Thank you .

You can flash the radio from version 4.4 that helps a lot, I'm at work just search this forum the directions are here, it's easy.

^^ He appears to be talking about the link below. You can flash different modems that may work. Some people say different modems helped but I've had no such luck. I've flashed every modem available and still don't have data almost everywhere I go. I have data at home but that doesn't really matter since I don't need my phone at home.

Did you try flashing your carrier's specific radio?
Team Nexus 5 sucks

Were would one find the carrier specific radio? I'm on T-Mobile but have only found the thread with modems. Nothing carrier specific.
Thanks for your answers. Unfortunately, flashing different modems does not seem to help .
i've read, the .15 is good with t-mobile.
i'm testing it today too. my problem is not only a signal drop, i have only edge too and my modem won't switch back to umts or hspa(+).
i'm in germany with t-mobile (congstar).
I have searched this forum, but couldnt find any thread with this specific issue, however there are some threads regarding the different modems available... have browser them but the sollution for me is still to find
Using nightly CM-12 with included modem, global OPO on the Telenor network in Sweden(2100Mhz for UMTS, dont have LTE on this SIM).
I installed CM12 as a troubleshooting-step after I tired using both the stock CM11s and CM11 nightlies. CM12 gave me the best signal strenght over all.
This thing is, I can get a good signal so the phone seems to be able to communicate with the cell-tower on the frequency used by the nerwork... but it is very unstable... Jumping from H/H+, from full to none signal-stenght. Also seems to change Cell IDs, this is even when the phone is stationary...
Even if I have an OK signal on H/H+, trying to use the dataconnection sometimes works, but often it would result in time-outs etc, even if the up/down arrows in the indication icon shows activity... Also sometime trying to use dataconnection when the signalindicator looks OK, it will drop to nothing... And speed-tests gives very poor results...
Dont really know much about how the physical layer for the mobile networks work, so dont know how to interpret this behaviour...
I have described these symptoms also in the modems-thread in the General forum, but having tried most of the modems, this is still the best ROM/modem combo...
Dont know if related, but using a WLAN-connection the HSPA cell connection is stable at around -103dBm... no flapping...
I feel that I have tried the most often recomended action with no appearant improvement, dont really know what to do now? Change modems, try to unlock additional bands... Any suggestions?
If any developer wants me to try any thing, or provide any more information I will try to do/supply that!
Update
Took the phone out to the local shopping center and got some surprising results...
Consistent -59dBm and around 20Mb/s downstream on UMTS.. So this beggs the question, why is it flapping up and down at home, where an old galaxy s3 mini sits comfortably at the same usable signal-strenght most of the time on the same network?
Is this a modem firmware thing, or antenna?
Hello,
I am new to the Android world coming from the iphones I had jailbroken. I searched for and found answers to a bunch of issues I had with this last flash but am not finding anything specific to my question below so I hoped someone might shed some light or point me in the right direction. I have a Xperia z3 6603 on kitkat 23.0.A.2.93. I downgraded the firmware from what it came with to get root which it now has, BL still locked. Over time it started acting up so I re flashed last week with a new downloaded ROM I used D6603_23.0.A.2.93_Generic_20GLOBAL.ftf.
The one last major issue (I hope) is the weak signal. I am on AT&T and since the flash I get max one or two bars LTE (full bars before) in the big metropolitan areas...briefly it goes to 4 bars. I don't get the signal strength on H+ I got before either so checked my APN configuration based on a post I found dated 2015 and it matches. I thought since it was a global rom I shouldn't have issues with the modem. Is there something I need to install or configure to get my signal strength back to where it was pre flash?
Thanks again for any help....definite android newbie trying to learn as much as I can so don't have to bug anyone.
Every firmware has its own radio ROM which is responsible for the signal/cell radio modem settings.
You might want to flash the ROM specific to your country, not the global/generic one.
If you want to play and tinker a bit, go to phone and dial *#*#7378423#*#*(*#*#SERVICE#*#*) to play around with Network Mode or the Antenna RX diversity tests.
Or you could try *#*#4636#*#* (*#*#INFO#*#*) to play around with Phone information.
Enjoy and good luck
