New Baseband Signal Loss - T-Mobile LG G2x

Not sure what is happening, but I constantly lose data signal either completely (with an X in place of the signal strength), or just the data like internet and email (but can still make phone calls and texting).
I'm using v21y with various ROMs, I have the new baseband fix that I'm flashing after whatever ROM i'm installing. The data drop will last for minutes, or until I restart the phone, or it will be gone until it decides to come back.
lastly I haven't received an email on my phone (but I have on my computer) since I've updated the baseband and started flashing ROMs. I'm considering reflashing the kdz file and leaving it unrooted.

I have this same issue, but I've had random data drops on previous basebands as well. The most "radio stable" I've seen this was with CM 7.1 on the v21e baseband after running GetRIL.
Currently running CM 7.2 RC w/ March 2012 baseband. Default kernel/voltage settings.

Alright well I've had good luck as of right now, I'm using the "slightly modded stock 2.3.4" that's in the Development section and I just downloaded GetRIL. The RIL is already matching my baseband, I'm also using Faux's latest v14b2 kernel for GB. I haven't had a signal drop for a few hours, which is saying a lot considering with other ROM's i've had data drops a hand full of times every hour.
Thanks for reminding me though, COMPLETELY forgot about GetRIL for some reason. Makes me second guess all the previous ROM's i've blowed over.
So yea, go this route if you want something that's actually reliable, so far at least.

Any signal loss since your last post?

Yup, I was using the MIUI that was built for v21y, and ran getRIL to fix the RIL but still didn't receive any e-mails overnight (i flashed the ROM a little before i went to sleep), I normally get at least 2 or 3 per night, never without ANY e-mails.
Saw I had the "H" in the signal bar, turned on Browser, "cannot connect..." bla blah, but I could text and call.
I was running Eagles Blood AOSP ICS yesterday AFTER I posted this thread, and I had NO problems all day, and I've flashed the Eagles Blood ROM again once I got to work and sure enough, NO signal loss.
As of now, for ICS, it seems like everything is good to go with EaglesBlood, and ONLY that ICS ROM.
As for GB, it's BuruROM P999 2.3.4 "slightly" modified stock.
Those are the only two ROMs, I haven't tried CM7, but those are the only two that don't give any signal drop.

I started with Stock 21y 2.3.4 -- everything was great, but I was missing the customization ofo other roms -- once 7.2 RC3 came out .. and the new libs.. i started trying other ROMS, but it just isn't as stable as stock 21y 2.3.4 was, so i reverted -- but I had lots of data drops/gps drops.
I re-ran GetRIL to download 21y again on stock (rooted) 2.3.4 --- and this solved the problems. So, if you are having data loss, my suggestion is to go back to 2.3.4 and reflash 21y RIL - this seems to do the trick..

Mobile Data- Total sudden loss.

Never had this issue where wifi will function without issues, although anything independent of wifi, which is data related, such as market, GT,will simply not work at all.
I attempted some common sense approaches to Apn, sip toggle but nothing.
Full connectivity is present in statusbar.
Regarding ROM. I thought is was my Rom when upgrading to a different version of Faux kernal, but unsure as I even reverted to stock kernal.
I decided to perform a super wipe and flash a new T-Mobile based custom rom with Faux built in.
previous ROM- Beast ROM.
Current ROM- HTC super light- HTC CLAY
This is where I stand now....
Suggestions?
Hi,
The same thing happened to me today. I updated my radio to no avail. Wasn't prepared to re-flash the ROM.
About 5 hours later, mobile data reconnected! It may have been a network-side issue, not my phone.
Has yours come back on?
Thanks for the post. Yea it actually did recently reconnect.
Maybe down as you referenced.

[Q] ICS on GRK39F I9020A (Rogers)

Hello, everyone!
I have a Nexus S from Rogers, Canada.
The Build number is GRK39F
Baseband: I9020AUCKF1
I'm running 2.3.6 and I'd like to know if anyone here has updated to ICS successfully with this phone. I want to force the update but I'm in doubt if it is currently working well.
Anyone?
No official OTA for the I9020A yet, but you could always flash a custom ROM from the development section if you are rooted.
Still waiting for the official OTA for my Nexus as well, but I think I am going to try CM9.
I9020A ICS Update
My experience with the AT&T/US version is that I was on 2.3.5 and would not get any other OTA updates.
I did manually update to 2.3.6 and did not experience issues with it.
I then unlocked the bootloader and rooted. No change to experience.
I then flashed the official full 4.0.3 ROM for the I9020T (at my own risk!) and then flashed a compatible radio and did not have any serious functionality issues, but did experience quite a performance lag.
Based on this experience, my take is that there is much to be done for the official I9020A ICS ROM with acceptable performance, and if you are going to wait for official, you are probably going to be waiting for a while.
I have been very pleased with the performance of a custom ROM dedicated to the stock ICS experience along with the recommended custom kernel. Blazing fast compared to my short experience with the official. I have done this all at some risk, but the XDA community is pretty awesome and with a lot of reading of feedback put me at ease and made it very easy to experiment.
I feel your pain
Same situation as you, forcing the checkin doesn't work because there simply isn't an OTA yet for the 9020a
hope it get's here soon!
Cheers,
JM
Worked for me
I have a Nexus S from Fido and I'm using ICS.
I flashed this ROM: http://forum.xda-developers.com/showpost.php?p=20456900&postcount=1
I didn't have to flash a different radio or anything. It all seems to work great. Should be the same for Rogers network.
Hope that helps.
ICS on Rogers 9020A
I did the same as ProfBurz yesterday. So far so good. no issues with battery life of reboots. Having some fun with my work exchange account right now but I'm not sure that has anything to do with this ROM.
My exchange account works
My work email is functioning fine. It didn't work the first few times I tried though. No idea why, I rebooted the phone and it worked.
One thing I notice is my contacts with pictures show up pixelated when someone calls. Wrong image size or something? They look fine in text messaging, just show up enlarged when calling.
I have a i9020a on AT&T and here is my ICS info:
Verision: 4.0.3
Baseband Version: I9020xxKB3
Kernel Version (stock): 3.0.8-gb55e9ac; [email protected]#1
I am also running Nova Launcher (beta 13).
My experience with this has been very good overal. I had some initial problems with data speeds with an earlier radio (can't remember which one), but with the new one (XXKB3) I'm getting about 2mbps down and 1mbps up which is good for the area I am in. I was watching last night at work and I got about 10 hours on a battery and I was only at about 46% then with moderate use (internet job searching some pandora streaming ect).
And just for clarification, this is the 4.0.3 ROM for the I9020T, as mentioned by the_real_nwags.
The few complaints I have are minimal and forgettable, but the app drawer takes a few seconds to open (slight lag), but once your in the drawer everything is silky smooth. The other issue I have is Google Wallet doesn't seem to work. Now whether that is my fault or not I can't be sure . The only other issue I have is while streaming Pandora, sometimes it will get stuck "Loading" the next song, but that usually happens right before a comercial, it normally goes right to the next track without a pause.
There is a slight lag to the system, but nothing horrible... I have used worse. So if your interested in trying ICS, this is a good start. I am thinking about trying a new kernal for increased cpu speeds, but I don't know about that yet.
I have a nexus s i9020A on rogers and as long as you flash a rom with no radio, like CM9 or cyberGR. I also have the AUCKF1 radio and 4.0.3 and all is well make sure to download the auckf1 radio just in case your radio goes wrong somehow. Good luck!

Signal

I have flashed a lot of Roms successfully, ever since I got the inspire (over a year ago). Sure in the early stages of learning the device I had some boot loops, flashes that didn't take, or just random items.
However, as time has past I have noticed a problem when it comes to signal.
When I flash a Rom I always use the recommended radio, and ril combo that is suggested, however, I flash all available radios for our device, to make sure I have the right one for my area. (Mississippi, Alabama, and Louisiana)
I have a device that doesn't like overclocking, past 1.2 normally, no matter the Rom or kernal.
So I keep the device a hair over 1G, for stability.
Now to my question.
When I flash GB with sense 2.1, I get the best signal, and GPS lock of any build.
When I flash GB with sense 3.0, the signal drops some, but still ok.
When I flash GB with sense 3.5, the signal goes away. (I know some Roms have a glitch in the display) however I totally lose signal, where I had full service with the above.
My question is? Is there a way to pull the radio set up from GB 2.1 and align it with GB 3.0, GB 3.5 or even ICS?
Or is this based off the RUU that the Rom is based off of?
The Rom that gives me the best radio and GPS is Rumrunner 4.0, and the worst is any sensation port.
I have found a lot of stable, clean, and fast Roms that I like, however, I always have to return to a GB 2.1 Rom, because of signal issues.
Any insight on this would be awesome!!
"This has occured on multiple devices I have rooted, and flashed for others, so I know it is not just my device."

What are you using to measure signal strength? If you are counting bars, each rom calculates them slightly different, only creating the illusion of different strength levels. Changing radios and rils often also isnt going to help you gain much. ive never seen a signal strength different between roms but i also have mine set to show -dbm so i know actual signal. Me personally, im using my gb ota radio as its given me the best signal retention out of the ones ive tried.
By the way, recommended radio ril that rom devs suggest is simply what they use on their device. They state this because this is the combination they know for 100% that it works. You are free to use whatever radio you want. and with sense roms flash the respective ril. aosp/aokp roms, do not flash ril (it will cause modem to not work until a reflash)

[Q] Why is Virtuous Inquisition v4.0.2 the only ICS that mobile data works on for me?

Please help if I am missing something. I am s-off wire trick. I believe I have the most recent radio. 11.59.3504.00P_11.16.3504.20_2.
I can flash the 3.0.53v8 or v9 kernels over this rom and most everything works but wifi so I am sticking with the 3.0.16virt kernel that is available with this rom. But I cannot flash any other of the CM9 or CM10 roms and get data. I have flashed them multiple times, tooled around with the vpn's got a new sim card, got a new phone (warranty), spent too much time with customer service at TMobile. Still, no dice. I am pretty happy with this ROM aside from not having DSP Manager or the ability to add it. Is it because there are still some elements of sense there like the camera? I thought it was a APN input issue but I have dialed in the same APN's as Inquisition for any other CM9 or 10 roms and nothing. Any help would be appreciated.

I know this is no help to your situation, but I've run all the available ICS and JB roms that are for the MT4GS and I have mobile data and wifi on all of them. There have been some issues where data drops occasionally, but it will reconnect in a matter of seconds. With the later kernels like r8 and r9 I had no dropouts.
I believe that Sense-based ROMS require a kernel that is built for Sense, so using a CM-based kernel (like r8 or r9) would definitely cause problems. Likewise, using a Sense-based kernel on a CM ROM would be unwise.
If you like Sense based ROMs, have you tried either the Bliss ROM from sun_dream (the XE 3.32 version, not the 3.33) or the MikXE ROM? Of the ICS Sense ROMs, I found them to be the most stable and battery-friendly right out of the box. For a CM/AOKP, the AOKP JB Milestone 1 is very stable and functional, and gets you Jelly Bean... even Google Now works well on it. CM9.1r9 is a great, very stable release, as well.
Just make sure you're doing a very thorough wipe before flashing any new ROM. Even go to Mounts and format the /system, /data, and /cache manually wouldn't hurt.
Thanks

So, I did the full wipe and flashed the newest cm nightly on my phone. No data. Did it again, full reformat et all. No data.Flashed the v9 kernel on top with no wipe. DATA! Thanks. I must have to flash things a few times for them to take. This wasn't a problem with the roms that had some "sense" to them. Weird. I've done the reformating before when I was s-on and never noticed any effect. Now I'm gonna try the CM10 you recommended. I like this phone a lot. The market is based around people buying new phones once a year at least. It's crazy. It's not fair that you can purchase a phone that 6 months latter has a totally obsolete Rom. I am so glad you responded. This makes my life a lot easier. Thanks!

It almost sounds like you're S-ON or still locked. Could you be S-OFF but Locked? You could always fastboot flash the kernel after you flash the ROM just to be sure, but if doing what you just did got the data working for you, then I wouldn't mess with it. If you do want the Jelly Bean without too many issues, I would go with the AOKP JB Milestone 1. The Paranoid Android JB ROM is also very nice, but it does require a little bit more tinkering.
I'm s-off jb from doing the wire trick. I have flashed that cm10 rom with v9 kernel. Have any issues with mms? Got any apn tips?

When you say cm10 rom, do you mean the AOKP JB Milestone 1? When I was running it I didn't have any issues with MMS, but I use Handcent SMS as my messaging client, not the built-in client. I also use T-Mobile and the standard T-Mobile APNs worked fine. I do see that some people are having issues with the r9 kernel, maybe if you flash the r7b kernel (standard, not experimental) it will be more stable. That seems to be the kernel some people find is the best combo of performance and stability.
Yes

Sorry I should have specified. I am in the middle of My CCNA2 and Comptia+ hardware exams this week and I was writing from my phone. AOKP Milestone 1, yes. I think it is the best CM10 I have flashed for MT4gs yet. Just a bit of a battery drainer and I've got an Anker. I tried hand scent this morning. Tweeked the APN's and now know way too much about the ins and outs of this phone not to just learn to become a developer
I got the rom to send MMS but not receive without it being marked as a download. So, coupled with that and the battery drain, I decided to go straight for the r9 kernel and it's rom. Supercharged and ultimate jar patched it. Pimp my rom'd it. And it runs very well, sends and receives mms fine. My issues seem to stem from a combination of problems. Yes doing a complete wipe and manual formats and flashing the specific rom and kernel helped ingrain the rom I believe. But the main culprit is those darn APN's. I finally found alternate APN's and after going through them all in every combination, turning on and off my wifi to check the mobile data latency in terms of how long it took to come on, I have discovered that a T-Mobile Data APN named wap.voicestream.com with the mmsc set to the /mms/wapenc, the MCC:310, MNC:260, and APN protocol of IPv4, with everything else not set of unspecified, allows my phone to come and go between wifi and mobile data with no latency, just like the sense based roms did. So far no drops, but have been bunkered down studying and doing last minute work. When I leave the house in a minute I am gonna be driving around for about an hour to and from where I am going playing spotify, so that should be some kind of test. I also tried internet2.voicestream.com but it was not as consistent of a mobile data signal. They are trying their best to control all bandwidth and software so we can spend a fortune upgrading our services and buying 3 phones a year just to have a proper interface. Most phones are going to only one LTE radio soon as opposed to one that will do data and one that will do voice, effectively making the devices less expensive for them to manufacture, but not for us to buy! Hopefully there will be enough of a niche market to have qwerty hard keyboard devices that are decent released periodically.
Has gone from a well intentioned but flawed technology to a stable streaming around this corner of my city. No drops. And spotify kind of sucks in comparison to other streaming services in terms of quality and performance. I don't wanna get too excited though, ill have to wait a month until I begin to have confidence again that ill have consistent data.

What city? Are you on a T-Mobile account? I'm in Atlanta and T-Mobile data is pretty good here, and I use the standard APNs (epc.tmobile.com). I also used my phone while in China, bought a China Unicom SIM and had excellent data using their system as they use the 2100MHz frequency for HSPA+.
Dallas, TX. Its solid around here but streaming high quality in a 40 mile radius could still be spoty with the meh quality of spotify, probably a load on their servers at rush hour, coupled with the fact that I've been so use to data drops. I'm telling you, the apn fixed my problem. It seems to be a known issue on these threads. Massive data drops. There needs to be a thread compiling alternate apns for people that have that issue with cm 9 and up. Double flash, full wipes, apn config. I'm on the cm 10 unofficial now with its standard kernel. Seems solid. Better battery life for my phone. Every time I flash a kernel I get intermittent data until I change to that apn above. Like zero to occasional. But now my data is tough as nails.

no wifi!
hey guys im s-on unlocked n currently running [ROM] [01-DEC-2012][r9] CM 9.1 + bat drain fix + usb trans speed fix + other tweaks right now and not getting any wifi. i am coming from the only rom that would give me wifi (virtuous inquisition) but that rom got too heavy too fast n was done on my phone. so i switched between a few other ics roms and none of them r giving me wifi.
i dont want to go back to virtuous inquisition but i need wifi. my setting just wont slide over. any help would be appreciated. THANKS!
Have you tried "fastboot flash boot boot.img" ? Using one of the boot.img files from the CM9.1 ROM you're running? It's a necessity when changing ROMs with S-On.
The big issue with no wifi as I've experienced s-on or s-off is that the rom is not sticking. If you are s-on do not try to switch out different kernels, just flash the whole rom. Also, id try the v8 version of that rom because it seems more stable. Go into your recovery, wipe cache, wipe data, wipe delvic cache, go into mount/format and format cache, data, and system, flash rom zip, flash gapps, fastboot boot.img, then let the phone reboot and don't touch it for at least ten minutes, reboot into recovery, wipe cache, data, and delvik cache again, flash rom, fastboot boot.img, and wait again another ten minutes or so while itg reboots. Don't touch it even if the droid comes up and asks you for what language. It is still loading. This is the usual issue regarding roms not sticking. Multiple flash of the same rom over itself and not touching for ten minutes or so after flashing. If you don't know how to fastboot boot.img get hasoon 2000's mt4g all in one program. It'll instruct you to remove the boot.img from the rom and place it into one of the folders in the program and will fastboot the boot.img for you. And btw, the wire trick is real easy. I didn't do it for a year but when I did I was suprised at how easy it was. Makes flashing roms less of a headache.

When flashing a ROM with S-On it isn't actually the ROM not sticking (although that may happen in certain circumstances) but it is that With S-On (security on) the kernel doesn't get installed at all thru CWM. You HAVE to flash that independantly & seperately & LAST And ALWAYS this way thru ADB with S-On. There IS no other way. (Save perhaps pushing that to the right partition thru terminal but that is another discussion altogether).
Yeah, what he said. And if your not savy with adb get hasoon 2000s all in one and it'll do it for you.

[Q] No Data after flashing Harsh Kernal w/ HellfirePhoenix 2.4.2

I was having a lot of FCs with the stock kernal(FAUX123). I flashed the HARSH kernal, and everything runs perfect on WIFI, except Talkatone is no longer compatable???. When I leave the house, I get no data signal -3G/4G. Any help? I looked through the Harsh Thread for the P999, but it is REALLY long now, and I gave up. Also, if anyone can tell me why I cant register for the ROM updates, that would be kewl, too.
Any help?
I should mention that this ROM/Kernal combo is the ****. got over 13hours battery time with wifi.
