[Q] Noob Questions - Thunderbolt Q&A, Help & Troubleshooting

Im very new to all of this but also very interested. Iv been reading allot of your posts but there still are a few things that im not grasping. If anyone can sum up one or all of these questions, it would help allot.
I just rooted my TB and have been flashing a few different ROMS(BAMF, Vanilla, and one other i cant think of) but on all 3 ROMS, my GPS will not work and my google calendar will not sync. Is this normal? I flashed plainjanev1 and it seemed to solve most of my problems, but its just like the stock and the whole reason i wanted to root was the possibility of changing my phone without losing GPS, Calendars, ect.. Does rooting and flashing a ROM usually mean i can lose things like GPS and Calendar?
Also, im lost on the concept of kernels and radio. Is a kernel something i can download to fix a problem i am having with my phone such as no GPS signal? And is a new radio download something that will help me better connect to my phone service?
I have many more questions, but dont want to bore you guys too much. Still reading through posts and trying to learn. i respect all of you that know this so well.
Thanks.

When you change ROMs, make sure you WIPE so that the new ROM gets a clean slate.

You should probably wipe your caches and even reset your user data when flashing a ROM. A backup app makes this a lot less of a pita than it sounds.

Nope, but you can have problems like this if you don't clean things up between ROMS.

I'll give this a shot but there are much more complete and better explanation than I am capable of.
The kernel sits between apps and physical hardware and manages the system resources.
The radio is firmware for the LTE, CDMA, etc. hardware in the phone.

The pic shows a basic outline of a kernel.

So basically, a kernel is the driver that help run the OS. And if i flash a new kernel, it will have a direct effect on how my OS operates.

basically. kernels are most often used to affect the way your cpu is utilized, affecting things like speed and battery life. they will not affect things like gps and calendars. those are caused by not wiping data. the easiest way to do this is to install the rom with rom manager. when you do it gives you the option to wipe data and cache, as well as make a complete backup of everything on your phone (including apps, data, homescreens, its basically an image of the moment on your phone). i cant help you with radios as im new to that topic as well. +1 to anyone who can give me a good description of that.

Kernels CAN screw up things like GPS and WiFi. Not on purpose of course but sometimes certain ROM and Kernel combinations don't get along.

Radio is basically what a previous poster said. When thinking radio think of signal. A cell tower broadcasts a signal to the antenna in your phone, and the radio is what turns that signal into reception. Its a piece of software, a bit like a driver, that regulates that interaction. You can turn on/off the radio, which cuts the 4g/3g/1x connection to your phone on/off.

VZW vs DCD

Ok so here is a quick question for you. I got my new device and whats better to flash on it? DCD or the new VZW release? Let me know and I will do it?
DCD is way ahead of the curb to any software release from any company, with his software it pays in spades what you originally got from the phone out of the box. GPS, PAN, DUN, sting SMS, faster better use of CPU and RAM the list is endless. hands down DCD's ROM is the industry standard.
the added value to the phone is nothing short of outstanding.
no question. dcd.
There is absolutely no way you can dobetter than DCD's Roms.

Oh boy, don't get me started. Read my rants in the thread I started about the official release. The only think worse you could do to your phone other than putting the VZW release on it is running it over with your car after pulling it out of the back of a dump truck thats filled with molten lava, uranium, and fast flying neutrino radiation. I would rather try conjuring the spirits of my dead grand mother in hopes that she could build a better ROM than this crappy, late to the game, outdated months before it came out, non supported, lacking GPS , bullsh*t ass VZW ROM.
I guess what I am trying to say is I would go with DCD's ROM ;c)
DISCLAIMER: Before anyone gets offended, this is solely my opinion (granted taken to an extreme!). Thank you for taking the time to view.
what i think is sad is all the people who won't flash anything but stock have suffered through all these months with 2.09 only to be rewarded with a crippled 6.1 with useless gps.
at least now you can unlock and flash to dcd knowing that you can revert to stock without bricking since you now have a stock gps rom. that is going to be the only thing this rom is good for.

Why do people continue to insist that the phone GPS is all that and a side of fries?
Has it ever occurred to you that some people dont give a rat's behind about GPS functionality on their phone? Guess what, I dont - I have a dedicated autonomous GPS which blows the crap out of anything you will get on your 6800's "gps" function.
Its not all about GPS you know - imagine that? There is a universe where things other than GPS is important
I've also tried a few of dcd's roms - great stuff - no doubt about it. But for the apps I run, the stock ROM seems to be better - blows your mind, I know.

I have a number of dedicated business and medical applications that run better with the stock rom than a few custom roms I've tried. For what/how I use my 6800 for, stock edges out custom roms.
If you use your 6800 like a toy, than its possible that a dcd or similar rom offers benefits. But for my purposes, the custom roms werent cutting.

Sorry, but those applications are just that - applications. They arent the same thing as what you can get on a dedicated unit. They are nothing more than maps - just like mapquest
But if you want something that a dedicated GPS unit can do that the 6800 cant with GPS enabled I'll tell you....
Real-Time traffic
And no, you dont have true real-time traffic on the 6800 since it isnt capable of accepting FM RDS signals
Listen, there is no sense arguing about it further - if you are happy with the GPS on the 6800 then isnt that what matters? I was not, hence, the reason I dont care about the whole GPS/custom rom thing. Enabling GPS on the 6800 was such a low priority for me since I didnt need it.
If you are happy with it and it serves your needs, then great.
If you want to continue this conversation, PM me - no sense clogging up this thread anymore
Well, I asked. I have never ran one of those programs so I have no idea how they compare to stock/DCD roms.
I use my device like a "toy" as much as I use it for e-mail, Excel editing and other business type applications.
Thanks for educating us.

I usually refrain from posting, but err wha? This confusingly senseless posts seems to have dragged me out of my cave...
Is FM not only used as a very low cost alternative to using Cell Phone Data Networks? It is the same network built out by MS to support their MSN Direct Watches that they are now leasing to services like Garmin for GPS Traffic... Since the tech you mentioned is simply there to give the "real" GPS device access to data, how is it any "better"?
Do they release updates to their non-PDA GPS setups faster? Otherwise, it should be the same (provided the cell phone has data coverage)...
Unless Garmin doesn't provide real time traffic at all on their PDA stuff?
I too am curious on the apps though... As DCD 3.2.6 is the fastest ROM I've ever touched on my Mogul (not saying much since I've only owned it 1.5 months and have only ran Stock + Stock latest + DCD 3.2.5 and 3.2.6). It runs everything faster and just "better".
I don't use my PDA as a "toy" so I'd recommend you not lump anyone who doesn't do exactly what you do into the kid with a toy category.
Depending on your applications needs you might be better off using the kitchen for DCD roms to be sure the stuff you need is included.
I had to add the Enterprise option to my ROM so it would sync with my exchange server (as my phone has to be able to enforce my corporate exchange policies).

Its only a pointless post if you didnt go back far enough in the thread to see where someone was asking me about something specific.
Either the 6800 is capable of receiving live traffic updates or its not - it obviously cant get RDS so we know its not getting updates there. Can it get it over another network?

EXACTLY! Thats what I've been saying all along - depending on your needs, the stock rom will be fine or you may need to go with a custom rom
Now we are back on topic
My TomTom software pulls real-time traffic. Live Search can even pull the traffic in real time..provided you have a data connection.
That is the real difference, not that it cannot get the traffic but the method it does and if it costs anything. I got the unlimited data so it is a non-issue to me, but with a limited data plan a dedicated GPS will win out based on that function alone.

What medical app runs better on a stock ROM than on a dcd ROM? Please name any specific app? Lexi-...? PocketMed? Harrison's? Even Epocrates?
If you're going to make this claim publicly, back it up with ANY specific app you've used which runs better on stock in your opinion so others can weigh in or test your claims. That's only fair when you're slandering dcd ROM's as better for "play" than "work." If you have "a number of..... apps that run better with the stock rom" surely you can name at least one, but I notice you don't.
I say, put up or shut up.

Then why waste your time posting here then? If stock if great for you then why waste your time on a forum for making custom ROMs? I think the GPS in the Titan is just as good as any hand held. TomTom, Live Search, Google Maps and others all can receive realtime traffic through the standard data network. Also TomTom devices are Windows CE embedded devices and use bluetooth connection to a data phone for the real time traffic and other services. So for me having one unit that I can carry to do GPS, email (work and personal), Geocaching, Bible, and internet search is invaluable. Since VZW seems to want to charge for using the GPS then we have DCD. If you don't care about the internal GPS then be happy with the stock ROMs. Better or faster is a matter of opinion that is true, but if I don't have to deal with all the bloatware that comes with the stock ROM the less that will take up precious memory. For me DCD/GC has made my phone a tool that enables me to work outside of my office, it is definitely not a toy.

I've read every page of this thread prior to posting. I read far more than I post by a long shot. I rarely post without listening (reading) first.
I posted because FM RDS is simply a data connection. Nothing more, Nothing less. With that in mind it would mean as long as the 6800 has a data connection it should show the same exact traffic information as a standalone "real" GPS device, unless either real-time traffic isn't a provided feature or the traffic provider prioritizes one device class over another.
Sorry but I tried 3.2.5 and 3.2.6 and found the stock rom to be faster

I wasn't slamming you as being inaccurate in your usage findings. There are far too many variations of this device to be absolutely certain they don't have more than just cosmetic differences. I was just adding to the thread collective my experience of DCD being a LOT faster than stock. As I also pointed out, my experience with the Mogul doesn't run that long. I just recently moved to it from my HTC Wizard.
Although it does help if you cite specifics. Such as "App XYZ runs faster" or whatnot so someone else using it can chime in and agree or what not. Unless you wrote the app for yourself you can't assume none of us run it

Please helpppp.. ICS is ruining my Note experience. I hate my phone right now.

Alright so I've never rooted my phone or done anything fancy with it as far as that goes. Recently the ICS update was released and I didn't update right away, wasn't sure how bad it would mess up my current settings etc. After reading that it retained all my settings and functionality I decided to upgrade. Ok so first off I can't Tether anymore and my portable wifi hotspot does not work either, I'm on Rogers and in Canada, never heard of 'tethering plans' such as other people refer to with AT&T. I have my 4g enabled, can retrieve internet access, and as soon as I turn on my portable hotspot my phone is unable to access the 4g anymore, It enables a wifi hotspot but anything that connects to it gets limited connectivity and can't access the internet either. It's like the phone just shuts it off automatically. I used to use this all the time and was one of my favorite features about my phone.. If I'm unable to use this I don't even want the data plan that I currently have, the data plan I decided on DUE to this feature.. So I'm gonna be pretty pissed off if this amazing little update is trying to force me to pay for something that I already pay extra to utilize properly.
I could be wrong here but I'm pretty damn sure that the battery life has dropped by close to 20% I can watch the percentage go down while I'm doing stuff and it seems to be losing life a lot quicker now, and I noticed that after the first day of using ICS. The resolution on the unlock screen seems to be botched, It's very squished... My old version never did this, and it's kind of annoying for my background images and having the clock looking out of whack.
I'm not sure what to do, there doesn't seem to be an update and as far as I know the update has been out for awhile now, why hasn't this stuff been fixed, who can I make official complaints to as far as Samsung or Rogers goes? I've checked these forums a bit and people seem to be having a lot of issues, some similar to mine some not, some I may have just had the luck to avoid so far. Is factory reset the only real option to fix things, and will that even help my tethering issues?
Also things like browsing through Facebook can eat up 5% of my battery in five or ten minutes... I know for sure that it never used to do that. I don't get why the battery life would be effected so drastically, but even when It's just sitting around while I sleep I lose a higher % of battery life than I did before... I've browsed through various threads but there doesn't seem to be many options, is anyone able to respond to the issues I'm having?
Flash a custom ROM. It's easy, and the experience is much better. There are guides in the stickies on everything you need to do.

Like he said above me, flashing a custom rom would fix your problems. I'd recommend CM9 ICS. It's pretty stable and my favorite so far. Downside is you lose S-Pen functionality.

I had the same problem and found two possible solutions:
1- I installed foxfi and i was able to use the wifi hotspot. I still wasn't able to access the native wifi hotspot functionality on the phone, but foxfi did the same thing so no big deal.
2- factory reset. this option is a little radical, but as has been explained elsewhere on this forum, the upgrade doesn't clear some configurations that remain from the GB ROM and those conflict with things like wifi hotspot and cardock and several other things.
I had to eventually do the factory reset. It was a nuisance because i had to reinstall everything, but now my phone works great and I can access all the native functionality.
You could also flash a custom ROM, but I have done it and while they are faster and sexier than the STOK ROM you always have to give up some functionality and they always have some bugs, and once you start flashing custom ROMs you can get OFD and we may lose you forever... (I had it from my windows mobile days and I would flash a new ROM sometimes more than once per day)..
Root (flash cwm with Odin), do a factory reset, and then flash the rooted/deodexed version of the UCLF6 stock rom. You won't lose ANY functionality, and your phone will be quick as hell again -- or even faster.
Like paleh0rse state...
Here is the thread with all the listing for stock LF6; tools that may be required. Along with all the ROMs.
http://forum.xda-developers.com/showthread.php?t=1740367
If you gonna flash a rooted/deodexed version of the UCLF6 stock ROM, no need to root before hand, just put CWM on and flash away.
Foxfi worked for me. But it doesn't connect right away to the Internet, had to inniate a browser then it connected.

XDA is no longer worth my time.
Factory reset fixed it for me.
TimOster; I did not use Klies, I am with Rogers so I assume it was one of their Roms, It was a wireless download but through my homes Wifi I believe. And I don't really think I did it manually, I got an update message on my phone one day didn't even realize it was ICS at first, but of course it gave me lots of warnings and obviously realized what it was before doing it, but I wasn't expecting this lol, I wish I had checked it out online first I would have seen all the complaints and just stuck with the old version.
I'm thinking about trying a factory reset first, and if that doesn't fix things, mainly the battery issues, then I'll try a stock rom.
No one seems to mention anything about the battery usage though, am I the only one noticing this effect? :\
XDA is no longer worth my time.

I'm in Modem-Hell, please help me get out!

Hello fellow XDAers,
after switching over to my dads old SGS2 (i9100) i'm having nothing but problems. I'm in germany and use a O2 prepaid reseller for phone and mobile internet. I'm a happy user of CM ... have been, anyways. After a while of use (~2 months) somehow mobile data would be unavailable after leaving WiFi. After a while and trying virtually every fix proposed on
code.google.com/p/android/issues/detail?id=40514
i started thinking "uh, maybe my old modem firmware isn't quite the best idea ... after all, many users report that new modems both fixed that problem AND increased battery life and mobile data performance".
This is where
all
started
going
down.
I've since tried many Roms, including the ages old official samsung one, and every 2nd or so CM since CM9.0. I've tried many Modems, including the ones reviewt on
eric10234.wordpress.com/2012/07/13/samsung-galaxy-sii-i9100-which-modem-is-best-part-4/
As well as the "good" ones such as BVLP*, XXLP6, XXLQ6, NELP2, NELP4. Each on many Roms. I've tried each Modem with the stockroms RIL, the CM versions RIL, as well as the "correct" RIL obtained by the GetRIL app.
NONE OF THEM WORKED. Some worked better ... whereas better means "sometimes a connection ... maybe even phonecalls for 30 seconds", whereas worse means a 40°C Cellphone after 5min and not even a signal indicator in the Statusbar... yay.
Now i'm kind of lost. I don't know what else to try -- especially if even the stock roms fail. I somehow have the feeling that this is not hardware or carrier related, so i still suspect this to be some kind of software ****up.
Please help me getting this straight again ;(. Thanks in Advance / for reading. Best Regards
- Dario Ernst

NONE OF THEM WORKED. Some worked better ... whereas better means "sometimes a connection ... maybe even phonecalls for 30 seconds", whereas worse means a 40°C Cellphone after 5min and not even a signal indicator in the Statusbar... yay.
Now i'm kind of lost. I don't know what else to try -- especially if even the stock roms fail. I somehow have the feeling that this is not hardware or carrier related, so i still suspect this to be some kind of software ****up.
Please help me getting this straight again ;(. Thanks in Advance / for reading. Best Regards

*EDIT: I've also dumped a radio log of my current combination (UNKNOWN RIL, BVLP6 Modem, CM10.2-NIGHTLY): tmp.kanojo.de/radio.log ... unfortunately its not very informative to me ... except ~something~ goes wrong.

Have you run GS2RomNuke @hawkerpaul inbetween new roms?

I must admit that i haven't. However, i somehow fail to understand how not doing this could lead to my problems. The modem firmwares and RILs are ~5 files which, as far as i understand and can try to verify using strace, ltrace and gdb, do neither read any config files, nor read additional binaries or libraries.
That said, i'll still try making a titanium + CWM backup, backup those on my computer, and try this and reflashing a current CM. Lets see whether that helps.
Thanks for the pointer, i haven't stumbled upon that script collection yet .

Have you tried getRIL to verify and ensure you have the RIL? Find it also on google play :good:
Still - if you have been flashing different roms and never done a thorough clean I recommend you do!

With each iteration of flashing a certain Modem on a certain ROM, i've tried both, the defaul RIL that came with that ROM as well as the matching RIL that GetRIL suggested for this modem. It usually made things worse for me though -- sometimes as bad as bootloops ;/.

Well, depends on what a thorough clean is. I always format /system, format /data, format /cache before i flash a ROM. I then restore the apps + datas backup i've made with titanium.
To be on the safe side, however, i'm going to take a few hours to tinker around with those wipescripts JimSilver posted before...
Thanks for your help! I'll report back .

Heyyas Everyone,
soooo, after a few days of use i must say ... i do not understand why this works! NOT AT ALL! I've left the BVLP7 Modem that i had, and used the RomNuker/RomWiper Scripts, then reflashed CM stable, restored all my stuff with Titanium and ... IT WORKS! I get very good reception almost everywhere, and Mobile Data is available directly after leaving WiFi, with only minimal noticable handover time. PERFECT!
THANK YOU GUYS!!!111oneoneone
The only thing thats left now is that the modem seems to drain battery *quite* heavily. No matter what resource intensive applications i use, not even 3D OpenGLES Games get the cellphone warm. One 250kb/s download and the thing is BOILING. Also it tends to eat up lots of battery when there is no signal. That was way better before, but i'll start digging around and searching for a fix.
Again, i wouldn't have thought that something so simple makes such a difference! THANKS!
Best Regards

[Q] Unstable performance with all ROMs

My EVO 4G LTE has, with all custom ROMs, lost stability after a month or two, developing different arrays of performance quirks or problems.
I'm interested in if there's a way to test the hardware on the phone? I'm tired of switching / reinstalling ROMs.
At first I thought the problem was that the ROMs were unstable but I've chosen from the bet ones available - PACman, Viper, a couple others I can't recall right now. The phone is rooted via Dirty Racun FYI...
Currently, with Carbon, the problems consist of:
With screen lock off, when waking the phone via the power button, something on the current screen will activate, whether it's an app shortcut on the homescreen, or a function inside of an active app.
Setting for LTE / 3G will not stay on 3G (LTE coverage is spotty enough that I just don't use it)
Random crashes / resets / bootloops; occasionally the phone will freeze on the loading screen with the Carbon logo and require me to hard-reset it.
Once in a while it's ignored my alarm clock.
Usually when dialing out, the phone will hang and fail to connect / ring, and I'll have to hang up and dial out a 2nd time to connect / ring through.
With ROMs I've used in the past, the arrays of problems have been different but of similar nature. At first I was inclined to blame the ROM in use but as my phone is the common element between them, I'm interested in how I can determine if I have a lemon on my hands or what.
Thanks for reading this.
Go back to stock rooted and see how it runs.

I'm not unwilling to do that, but I have extra time this weekend to run diagnostics as well if there's any method by which that's possible? It seems to take a few weeks for problems to start developing when I install a fresh ROM.

Any such diagnostics when not on a stock ROM can be issues with the custom ROM, not the device. If they occur when on stock, that helps determine hardware may be at fault.
Most of the AOSP ROMs suffer from kernel and data issues because they use the same base. You might want to try the Android 4.3 RUU as well since that's the latest we have for the device.

Ah, thanks for this. I didn't think it would be reasonable to blame the ROMs across the board. I'll look into the 4.3 RUU.

Custom ROMS - Poor Mobile signal & reboot for mobile data req'd after wifi

So I have been trying various MM roms but have finally admitted defeat and gone back to stock.
For what ever reason mobile signals for Virgin (EE) by us is not great, but the OPx has proved the worst phone I have owned yet with regard to making best use of what reception we do get, (Still have OP1 and S7 owners in the house, so have comparison).
However, all of the many MM roms I tried only made things worse with either weaker signal (or that's how it appeared) or they were unable to handle the swap between Wifi and Mobile, always requiring reboot, once I left the homes Wifi in order to get mobile data working!
It's so bad that I am even considering replacing the phone, but it's hard to find anything else in budget and size with same spec.
Thanks to everyone here who builds these custom roms and all the accompanying support, but for now I will continue with stock until I miss MM facilities too much.

It's just face value which shows yellow line in battery graph as far as I can tell. I do not see any difference now. Transition from wifi to mobile data is fine here. I am using turbo at the moment. Give it a try. If you wanna switch to a new phone, moto g4 plus should be good choice.

Hi, sorry not sure I understand the first part of your reply.
Anyway, the truth is that apart from this recent damned data issue, this is close to the perfect phone for me (seriously couldn't go for anything as large as the g4).
I have owned the OPx since release and though mobile data was never the best, it wasn't as bad as it has appeared this last couple of weeks. I am hoping that I have had a 'perfect storm' of events that led to 2 weeks of poor data connections/transfers. Bad roms, poorly implemented, weak mobile data areas etc etc.
Therefore, I am going to continue with testing different roms and set ups and hope that I can fix the issue, because there is no other phone on the market that comes as close to my perfect phone as the X.
I second Turbo ROM but also try Validius. Using it right now I think they feed it steroids.
For me this solution worked when facing troubles with mobile data on custom roms:
(Re)install the stock rom, backup EFS in Twrp, do a complete wipe, flash custom rom, restore EFS in TWRP, reboot to rom, restore standard settings in APN / mobile data settings, reboot.
It solved my frustrating issues, hopefully it does the same for you!

Many thanks for replying, I had indeed seen your thread and tried the solution, though initially I didn't think it had solved my issue. However, due to there being no other phone I care for, I tried another rom and then reflashed the EFS backup.
And you know what, I think it may just have worked this time.
Thanks for your help and others.
Go try Sultans ROM. He recently switched to Oxygens RIL

That's the one I'm trying and so far so good
It would be great if someone could create a flashable zip with oxygen RIL to use on any custom ROM. Don't even know if it's possible? Perhaps @RJDTWO can enlighten us, do you have the expertise? ?
Sultan's rom is the most stable regarding cell signal quality and speed. I have tried lots of roms, his rom is the only rom that comes near oxygen, every other custom rom has considerably worse lte speed and signal quality
@cokesucker it needs integration with the rom as far as i know, i think Sultan made the modifications needed for the rom to work with oxygen RIL
Folks, Ive dirty flashed the latest Rom, which I assume writes over the stoc EFS restore I had applied previous version of this Rom
Regardless, the difference in signal (as well as other areas) is noticeable.
I love this phone again, thanks everyone.

This is unfortunately not possible. The RIL itself is built with the ROM.
been on o2os, cm12, cm13 now - never had issues you describe, you can try development settings keep phone data always active could easily solve your issue since data wont never disconnect

I tried most things and thought that occasionally I had solved it by 'forcing wifi' or whatever.
However, because much I what I did was reactionary rather than trying scientifically to identify the main issues, the causes probably got lost in location, reboots, resets, etc etc.
What I can say is that for 2 days, I have been using Sultanas latest Rom and it has worked flawlessly.
Nice, good to hear Bob!
I'm using that rom too, it's a real gem!
(Oxygen EFS restoring was still necessary despite the oxygen ril though)

That's interesting, I'm using "as is", and so far so good. I'm off on travels tomorrow will keep an eye on performance. Any issues and I'll restore stock EFS.
