Two Major Problems w/ TW Roms

Two Major Problems w/ TW Roms - Vibrant General

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.

internet/data issue due to different rom?

Anyone here seeing some data issues on the D2 running Fission? I am in a major city, and it seem like I am kind of having some data issues since I starting running Fusion, specially when browsing the web. The internet seems to lag a bit, and connection seems a bit slow(good bit slower than normal). I got a message few times relating to the data connection. I want to say this could be a network issue, but my sister with a Droid Inc, says here data is fine? Any ideas?

Called VZW today up asking if there was an issue on their end, and they said no. Tech then told me to take out the battery for 10-15 seconds and they try the internet when back on. Tech said it could be due to the phone not properly switching from one tower to another. It did work, but about 2 hours latter I was having the same connection issue where pages would no open up, and data was a bit on the slow side. Did the same method again, and that worked. I didn't have this issue on the stock D2 rom, or with my Eris(well that always dropped 3G reception, this is full bars with connection problem). Could this be due to me being on Fission 2.2.2, or is it whole different matter not due to being in Fission? Thanks

Im running 2.2.2 and im not having that issue. My girl has a D1 and she gets the same crappy service i get i really dont think its the rom. And i dont think there is enough of a difference between 2.2.1 and 2.2.2 to have one get different reception than the other
Shot from my level 60 crossbow of awesomness!

Maybe it just my phone then? I guess will see what I can do.

Have your tried a root reset with a reinstall?

I have been having this problem, Data will just stop working all together. Text messages won't get sent or delivered. The 3G icon just shows uploading and not downloading or stops showing anything at all. I can't fix it unless I turn on Airplane Mode then back off or reboot the phone. Right now I'm running Fission 2.1 but I ran into Data issues with the default R2D2 rom.

So the issue your having is not related to a fission rom...

So, I may have solved the issue. I started clean again; cleared all data and status and stuff, then reinstalled 2.2.2, and then hard rested. Only thing I did different was not install the black status bar and all seems fine, and data seems normal.

I hate to say this man, but from my experience, the more "stuff" you throw on top of a rom, the more bugs your gonna encounter. And youll never have the same bug twice...

Why is that?

Im not a dev or anything, but here is an example. I was having problems with a rom i was running last night, reboots and such. The very first thing the dev who made the rom asked me was if i was running a theme. Now, im not saying you shouldnt use custom themes or addons with these roms, but every device is different and will react different. And when your flashing 3-4 different themes over a rom trying to find one you like, or flashing addons then trying to undo them your gonna create some issues. Of course, and i remind you again that im not a dev, this is completely based on my experience, and opinion

I guess with themes that can make sense. I wonder what team defused has to say about this?

Great reception, but no incoming calls/texts

I have this problem for long time.
I have great reception at my office and home, and I do not hold the phone all the time, so its not death grip thing.
Many people complained that I did not answer the phone....
I would, if it rings..... My phone is always charged and out of blue, I got few voice mails. I tried make a phone call, my vibrant says calling and call ended.
I had to reboot my phone and its fine again.
I called CS many times and changed my phone twice. I still have this problem.
I tried almost all roms and modems, and I still have this damn problem.
I have been with t-mobile when they were voice stream, never had this problem until I got vibrant.
If anyone know any solution about this, please let me know.
I hate to leave t-mobile, but I think I have to if I do not find solution for this.
Help!

how often do you flash things? i had very similar issues that resulted from something getting corrupted. i odin'd to stock and reflashed and havent had issues since, tho i never tried flashing an alternative modem. I would give that a shot but chances are that odin will be your best bet.
Cheers

try a differnt modem

Pls post more infos:
Rom, Kernel, Modem? Apps?

I tried many, if not all modems and roms, so I can't provide specific rom or modems.

I've tried all modems kb5, ka6, ka7 no luck. I've tried bionix trigger stock toxic and sgs2 clone rom and still see the issue

I have the same problem. on bionix v1.3.1 modem kb1.
I generally have the problem in lower reception areas, but others phones i have don't have the problem. You'd think a great phone like the vibrant would be able to handle lower bar reception...

Wifi Issues

I was wondering if someone could please help me with this or explain it
I'm a bit of a flash addict, I flash at least 2 ROMs a week sometimes a lot more, purely because I love one day having a completely different phone to the one I had the day before. I've been on XDA since before Christmas and have been flashing that long, mostly in the back.
But with some ROMs I've needed to input full ip settings before it'll connect to my home router and at school, both of which are different so I have to stand there for a while typing it all in, but with others it just connects
I've tried different kernels (And scheduler) but that doesn't seem to effect it, as I always use lees latest kernel, but have tried others to fix this problem and I've tried kernels that I've had working on ROMs, so from this I deduced there's something in the ROM.
Normally (and usually) I'd just switch ROMs, but I would really like to use synergy so any ideas or help?
Thanks, Joe

GPS not working on any ROM...only stock+stock kernel

Hello all,
I've finally decided to take this problem to the entire forum.
I am a rom-crack addict and have successfully installed dozens of roms on all my devices. But i'm having trouble with the GPS on both of my TF101's.
Every rom i've tried works perfectly except for the GPS.
I can only get GPS working with a stock install + stock kernel (9.2.1.24 & 27).
I've got my TF101 installed on my car dash and really need GPS.
I've tried EVERY rom available and tried all types of fixes. here's what i've tried:
- tried these roms: CM9, CM10, EOS2, EOS3, megatron, revolver, AOSP, AOKP, Revolution HD, etc.
- tried Clockworkmod & TWRP....format system, wipe system, wipe cache, wipe dalvik prior to every rom install.
- used the kernel that comes with the roms.
- installed .24 or .27 kernel's over the roms (no gps unless i revert from rom to stock with these kernels)
- tried Guvenors kernels (all versions),
- installed AGPS flash fix (mount system, install) (even modified build.prop with GPS settings...although i didn't see any of the modified code lines that AGPS was supposed to install in build.prop.)
- let the rom settle for 1 hour each time i install
- tried the regional reset app available on the market
- tried to get satellite fix indoors and outdoors
I haven't tried these:
- snort salt and throw the lime over my left shoulder (can't find limes b/c out of season)
- trade up for a Galaxy Tab
Logically, if none of the roms work on my tf101, then there's something wrong with my tf101.
but i have 2 tf101's. no luck on both.
and i can get great GPS on stock 9.1.2.24 & 27.
thinking of getting an external bluetooth gps receiver, but don't want to spend another $100.
not having a rom on my tf101 sucks almost as bad as having an ipad.
can anyone dig deep and help me solve this problem?
thank you, thank you.

I have the exact same problem. I haven't resorted to stock, but I have tried many, many roms. No GPS love for me, either.

I have heard this before from some peoples, no GPS with any custom ROM. GPS work for me on all ROM I've tried. Currently on Megatron with Guevors v21.5. The kernel that's been modified by ricardopvz.
Have toy tried the app "Faster Sat Fixes"?

I had good GPS on stock, OK on ARHD and Revolver ( faster fix helped with these ) and nothing no matter what I do with my ASOP JB ROM I'm currently on.

Yes, i've tried faster sat fixes. believe that just speeds up the satellite aquisition. i've left my tf101 searching for sats for 24 hours inside and 4 hours outside on my deck. both with fast fix and without.
since stock works perfectly on both of my tf101's, it must be the rom or kernel.
i've literally made a variables matrix of my attempts...it's 3 pages long. i've tried every combination of installation proceedures, rom types, kernal types, app fixes, build.prop modifications, etc. IE: a+b, a+c, a+d, a+e, a+f - b+c, b+d, b+e, b+f - c+d, c+e, etc.
there must be some coding variable that is missing or not correct in all the tf101 roms. something variable that some pads like and some don't.

I used "1-Click Transformer Root_1.1" (says it uses the Niloj TF300 Exploit) to root my tf101's.
could that introduce a variable that the rom's/kernel's don't like?

Had the same problem with all custom roms I tried so far, till an hour ago. I am using latest eos with kat 1.0.1 and no matter what I tried i couldn't make it to fix position. With gps essential it could see 4 to 5 sats but no fix. I tried gpsfix and fastfix as well with no luck. Then I accidentally left the tablet at my balcony with gpsfix left opened and left the house. I when I came back after an hour I think, I had a fix with 6 sats. From that time I had rebooted several times, turn on/off gps several times and I always get a fix within seconds with a-gps turned off. I also got the tablet to another location (where I'm right now). Turned on the tab, and in 10 secs I got a fix. I hope it's solved. So my suggestion, give it some time for the first fix.

thanks, ark...i'll give it a try in a few hours...busy now.
if you'd have told me to hold the tf101 in my left hand and throw a dead cat over my right shoulder...i would have tried it.
will let you know.
thanks for the effort.

nope...no joy.
it is certainly recognizing more satellites, but i've only achieved lock briefly a few times. no where close to being "useable".

Unfortunately I'll have to agree.it's unusable. I tried it in the car and it couldn't keep the fix.
Sent from my XT910 using Tapatalk 2

Success!!! Yes, yes!
although it took another hunderd dollars, but i acheive full lock (hehe..) in seconds.
i bought the Universal Bluetooth GPS receiver by Dual, followed the instructions, paired it with my tf101, allowed 'mock locations' in system settings, downloaded "Bluetooth GPS" app from store, made 2 app setting changes, and.....voila!...GPS lock instantaneously.
Tried this on ICS Megatron & Revolver - JellyBean TeamEOS nightlies. all works fine!
yea, it's another $100, but it now makes my $1000 tablet useful.
hope this helps others.

Well, my situation improved. I used the ARHD superwipe-full script, then formatted each partition a second time for good measure. I flashed CM9.1.0 just to check CM's progress. I can at least see satellites now (nothing before), but it would be pointless to try and navigate this way since it doesn't lock very long. GPS-Status shows 5-6 satellites, locking on and off after 20-30 seconds of searching, and sometimes dropping out. When I was on stock HC and stock ICS, it would lock startlingly fast, with 10-12 satellites within 5-10 seconds.

I followed what you did and got the same results.
i would really like to return the external bluetooth gps receiver and use the one i paid for in the tf101.
I am at a loss as to what to try next. i have tried everything.
hopefully someone will stumble across this thread and post a solution.
Buehler?
Buehler?

Not much chatter on the CM threads about it either. I just set mine up in my car too and I really need that GPS too. Hopefully a fix can be found soon!
The only time I get any kind of location lock is when I'm connected to WiFi. Not good enough.
I'm a pain in the ass and I don't want to go back to stock because everything else in CM10 is working so nicely!

try the external bluetooth gps receiver made by Dual. it works with my tf101 perfectly...locks in 1-2 seconds. USB powered for your car.
it's $100 but chances are you've spent quite a bit installing it to this point...what's another hunday?
with all the developers do when they write these roms, you'd think someone could solve this in 10minutes.
maybe someone will think of something or devote some time to solving.

Same problem.- wish there was a fix.

The trick for me, whether on stock iCS or custom ICS, JB, has been to take a stock ROM, extract it to directory, blobunpack it, if necessary, and do the same with whatever custom ROM you want to use. You have to get to the ramdisk, where you can change the gps related settings in init.ventana.rc to match the same user and group and permissions as in the stock ROM. On JB, I compared to the TF300T JB firmware and made a merge of the settings there with the stock ICS settings. Also, use the /etc/gps.conf from stock ICS, where there is only 1 line setting an NTP server. Asus seems to have gotten the gps right on stock firmware. Works like a charm for me. After the changes, you just repack the kernel and ramdisk, blobpack it back to a blob and recompress it with the 2 original folders and reflash and you will have working gps, barring broken hardware, of course. If you are on a stock based ICS ROM, you should be able to flash one of appropriate stock ICS kernels I have posted elsewhere in the development forum and achieve the same thing, although you will still have to manually make /etc/gps.conf match the stock setting.
I did this process earlier with K900's Jelly Bean AOKP ROM and now gps is working like a charm. It worked somewhat before, just very slowly and couldn't hold a fix very well. The first time takes a few minutes, but after that, I see 8 to 10 sats and get a fix in seconds, sometimes fixed to 8 at a time.

SidneyK,
many thanks for your input!!! so there may be a chance?!
I'm a dedicated crackflasher, but have never compiled, blobunpacked, etc.
I know it's alot to ask, but could you possibly post a detailed process? what apps to use, exactly what steps, etc.
I've had many, many PM's from members who are suffering this.
No rush, we're patient for news like this.
tell me how to buy you a beer and it's done!
many thanks in advance.

Well, I don't use PayPal, so don't worry about the beer. My wife had a PayPal account she hadn't used for years and it got hacked, so I don't trust them. When I get time, I'll try to put something together with the relevant links to threads with the supporting tools and a run through. It's kind of convoluted since everything isn't all in one place, but once you understand how the different pieces go together, then it makes sense. Mostly just remembering to do each part in the right order. Once you have the tools though, you'll see that you can make other changes like this or even further customize any ROM yourself the way you want it or to experiment with things.

Very much apprecieated.
just by your brief overview, it seemed logical. but i'm sure there are many nuances that go with it.
i'm also a cracktinkerer and can't wait to really see how rom's tick.
whenever you can post it, you'll gain even more fans.
thanks again.

[Q] Phone reception/broadcast on CM and ASOP roms

I have tried many times now to use CM or ASOP roms and their like and I find that I consistently have the same problem: no phone calls in (I would boot the rom and then call my cell from my house), can't hang up after a phone call and lousy GPS.
I don't have these problems when using a stock (Touch Wiz) based ROM.
Why is this?
Clearly it's a software issue, what could possibly be missing in the various roms that would make this happen?

Software version L720VPUFNAE
Hardware version L720 08
I'm running team acheron's super s4 right now and I therefore cannot update the prl or profile,
I'm international right now (in Israel) and I therefore used the radio unlock method from the forum here to unlock to phone for GSM and UMTS usage.

Has anyone experienced this problem and has suggestions as to how to fix it?
Thanks

I flash a LOT of roms. Sometimes two or three a day. (I am going to meetings but I will always be a flashaholic.) I am almost constantly on AOSP because I do not like how clunky TW feels and there are about three or four things an AOSP rom does easily that you cannot do easily or at all on TW. I have had all of the problems you mentioned at one time or another but never all at once. When I first bought my SG4 and started flashing roms the GPS was a big issue but that problem is pretty much nonexistent now. The same with the inability to make a call. I have not seen that in awhile. I recently flashed a rom that I thought was running perfectly until I made a phone call and could not get the phone to hang up. I had to reboot to get the phone to disconnect. That was the first and only rom I have had that problem with. I think I reinstalled it a few days later after it had been updated and it worked fine.
Other things I have noticed is that Google's voice recongition does not work as well on AOSP roms and there can sometimes be a problem with MMS.
I say all of this to say that first, these roms are in development. They are not perfect. They sometimes have problems. If a rom has a glitch you cannot live with, go to a different rom.
Next, you have to follow the installation instructions to the letter. If it says to stand on one foot while installing the rom do it. I have seen some roms that have really weird install instruction but if you do not do it, the rom is not going to work. Acheron's Super S4 has you use specific recoveries and reboot into recovery. That is a little odd.
Next, if you feel you are constantly having these problems with all AOSP roms, which is odd, try flashing a stable version. CM has milestones. I know Liquid Smooth has an official 3.1 that is supposed to be very stable. See if you have these problems are more stable versions and instead of nightlys.
Next, I have seen people on the exact same model phone and carrier have greatly different experience with a rom. Individual phones seems to have their own quirks you have to learn. I believe most of this type of issue though is user error and you just don't realize you are doing something wrong.
Finally, the one thing I know nothing about is unlocking your phone for the international version. I wonder if that has anything to do with your problems.
Good luck and don't give up!
