[Vibrant Q&A, Help & Troubleshooting] ezspassov:
Hi everyone,

I recently began experiencing network issues on my Vibrant (would not work on 3G, only EDGE) which did not go away with any troubleshooting steps.

Yesterday, it crapped out completely and refused to connect to the network at all. No calls, no data, just a "Not Registered On Network" message. It wasn't the SIM card either.

I did a soft reset, hard reset, factory reset, and ended up flashing the latest Bionix rom (1.9?) with Voodoo and the whole deal. That still didn't work so I called T-mobile and requested they replace it under warranty.

So my questions are:

1) The phone is not only rooted, but flashed with Bionix 1.9 (JAC UV Voodoo). Will that cause problems with the warranty?

2) If yes, would flashing to a stock ROM fix that (disable Voodoo and restore from Odin)?

3) If the warranty is VOID, what will TMO do?

I asked the rep but she wasn't very helpful at all.

Thanks!

You coyld just delete everything on the phone all apk all apps and send it in all there going to so is reinstall there info when you send it back I don't think that they communicate with eachother about stuff like that if they did customer service would know more about flashing roms and actually be able to help more when something gos wrong other than a series of resets

I would flash it back to stock via odin... why take the risk they might say something. Its easy takes and takes next to no time to do.
[Vibrant Q&A, Help & Troubleshooting] ezspassov:
That's what I'm thinking too. I'm going to do that. Does that clear root though?

@willsnews, I'll try that too. I don't want any trace of my stuff on the phone anyway.
[Vibrant Q&A, Help & Troubleshooting] s00thsayer:
replacement phone

ezspassov ... mind sharing the status of your replacement? my tmo samsung vibrant (18 days old) crapped out on the 12th within 24 hours of receiving the JI6 update from tmo. phone will no longer boot. got it to boot a couple of times but all the apps force close even after a user data wipe (guessing it's a hardware problem). tmo was to express ship out a replacement but today the order status was changed to BACKORDERED! :mad: did you get your phone or is it also backordered?
[Vibrant Q&A, Help & Troubleshooting] cthach11:
Yes, flashing the stock rom through odin will remove any system traces of root. On the other hand, make sure your smart and delete any evidence manually through the file manager on your internal and external sd card. For example: Don't leave a bunch of zip files lying around named "Root", "Bionix rom", etc....Be smart...
[Vibrant Q&A, Help & Troubleshooting] likeitnot:
That's crazy because I am having the same issue actually. I had to order a new one.

Anyway, the loyalty rep assured me it would be easier for me to just do a warranty exchange (and assured me it would be brand new, which I doubt very much but eh whatever) instead of of sending back this one and doing a whole new order and waiting long times for my account to be credited and all this crap.... anyway I went along with it. Well I called today to get the tracking number cause she told me to and found out it was on backorder. Hoping it isn't on backorder for to long cause I want to get to enjoy my phone fully.

I asked if I could just send this phone back, they could cancel the exchange, and then place a new order (the backorder is only for exchanges they told me) that way I know for sure I am receiving a new phone cause I am still under the 14 day buyers remorse period but after a 20 minute wait, yes 20 minutes, they came back and said they couldn't place the order at all (I was going to pay with my cc).

So I said eh whatever just go ahead with the exchange in hopes that it won't be to long before they come. I know the rep told me they've been on backorder since the 13th, smh.
[Vibrant Q&A, Help & Troubleshooting] OmniNut:
So..

So what if I had flashed nero beta 2 and the phones rooted and not only can I not enter clockwork recovery anymore but my phone isn't recognized on the USB ports so I can't Odin back to stock. I get the "USB device not recognized" even though I've manually installed all samsung vibrant drivers. How would I go about erasing all the data now? Any help would be great cause I'm not sure what I can do with the phone now.
[Vibrant General] nights62:
I have read these forums for a long time but this is my first post. I recently updated the JI6 via the official T-Mobile over the air method. I have been on JI6 for two days now and have noticed that my battery life is terrible. Usually I am able to make it through a day of average use without any problems and I charge at night. Yesterday my phone did not make it through the day and it was a low use day at that. When I got home from work I started charging the phone, before bed I unplugged it and figured it would be no problem to just leave it in standby all night, my previous experience was that a night of standby only dropped my battery by a few percent. When I got up and looked at my phone before leaving for work it had already dropped to 21%, I looked at the battery usage statistics and found that Cell Standy and Phone idle had leapfrogged over display which is usually the biggest draw of power and were now using significantly more power than even the display. Also I do not live in an area of poor cell phone reception so that could not have contributed to this.

My phone was pretty much stock besides being rooted to run the WiFi tether. My wife also has the same phone and she said she is experiencing pretty much the same thing since the JI6 update.

Below is the list of the top 4 batter using processes were on my phone and their percentages.

Cell Standby 41%

Phone idle 30%

Display12%

Android System 9%

Is anyone else experiencing similar battery usage since the JI6? Is there a known problem with this JI6? Has T-Mobile or Samsung acknowledged this problem? Any suggestions for fixing the problem at least until Froyo comes out?

Perhaps others can post their experiences with battery performance post JI6 here as well so we can get a consensus.
[Vibrant General] kangxi:
The radio in JI6 is stronger than previous versions to help with reception. That being said, it drains battery more. However, the stats your provided seem to point to you having apps on your phone that are pulling internet information too often. My cell standy or phone idle is never higher than my display and I do use widgets and apps that update a lot.
[Vibrant General] heygrl:
There just seems to be a bug somewhere that causes random drain, I've seen what people are saying about and I pulled the battery, it stopped draining for me until I guess I trigger it again.
[Vibrant General] nights62:
I do have some apps that are pulling data down from time to time, but I have been careful about setting these apps to not update too frequently. Also last night I specifically went in and closed any unwanted running apps, I think the only apps I left running were Seesmic, K9 Mail, and Gmail.
[Vibrant General] kevoh:
This thread is precisely the reason for why:

a) I finally registered to xda-developers for support

b) I decided to root my Vibrant

I received the JI6 OTA update around 5 AM on Wednesday, thinking *oh sweet this must be 2.2* I didn't hesitate to install it...the first 24 hours after didn't seem to show much signage of battery drain, but by Thursday morning things seemed...off.

6:00 AM - 100% charge, fresh off the cord

Around 11-noon - 15%, low battery notification pops up

This was by far the quickest drain I've seen, and even though I've only had my Vibrant for a month...right out of the box I was getting spectacular batt. performance with light-moderate use + wifi + sync, lowest brightness*(auto off), somewhere around 24-30 hours.

My initial reaction was to reset to factory, only to discover here that it did absolutely nothing to remove the JI6 update.

Now, post-root I've been reading through similar threads about the OTA effects and finding all types of tricks to extend the batt. life. Today the battery hasn't been as bad (with nearly everything off...sync, intervals, gps, blah blah), lasting around 11 hours. Not sure if there's any fix in sight, though I'm not really anticipating it reading how the cell standby / baseband is cranking out more power and in effect more juice.
[Vibrant General] lolcopter:
My battery is about the same as before, getting 24-30 hours out of normal use. I'm currently 14.5 hours unplugged sitting at 42%
[Vibrant General] lftl:
Flashed JI6 via Odin, and my battery life has sucked since. Talking on the phone kills it especially fast. I talked for about 45 mins yesterday morning and the battery gave out after 7 hours. Today it at least lasted 12 hours, but that was with pretty much everything turned off. Anyone flashed back to JFD? It's not like JI6 brought anything to the table.
[Vibrant General] Yellow C6:
My battery drains while idle after the update. Yet my wife's phone battery is fine. Hers is stock and mine is rooted with mobile AP flashed. I even reconditioned the battery.

Tonight I decided to flash bionix 1.91 rom to see if that would fix the battery drain issue. So far it's looking good. I'll know better tomorrow after a full charge.
[Vibrant General] boomerbubba:
JI6 installed Media Hub, right?

Sprint Epic users found that when Media Hub was installed on that platform a couple of revs back, it loaded a DRM background service that is constantly running even if Media Hub is never used. It is now pretty standard practice among knowledgeable Epic users to stop the DRM service whenever the phone boots. Many rooted users go further and delete it.

Vibrant users might try the same methods to improve battery life.
[Vibrant General] tissimo:
My battery usage has been fine. I installed through mini kies though rather then the ota.

Sent from my SGS Vibrant.
[Vibrant General] sumasage:
It totally sucks for me. I have tested it throughly this past week. Ran JDF and left it idle over night, barely lose any battery life. Update to JI6 via kies mini and lost 30% over night while i'm sleeping. I also tested the various versions of JI6 posted on xda and all of them give me horrible battery life (losing 3-5% per hour doing nothing).

I'm flashing the JDF modem file on the JI6 from kies mini. Will report back...
[Vibrant General] lolcopter:
Again I'm completely confused here. Running stock JI6, went to sleep last night at 24%, woke up this morning at 21%
[Vibrant General] kevoh:
I removed mediahub via titanium and a bunch of bloatware while I was at it yesterday morning, I can report that last night before dozing off (11:45 pm) battery was at 90%, this morning (8:30 am) its at 63%...37% loss in almost 9 hours. Only wifi on throughout the night:

Display: 41% (brightness 0)

Cell standby: 27%

Phone idle: 19%

Android system: 7%
[Vibrant General] heygrl:
That makes no sense, if you're on WiFi it wouldn't be the cause of this. Are you sure it's set to be on WiFi 100% of the time/when the screen is off?
[Vibrant General] lolcopter:
That's ridiculous, something is awry
[Vibrant General] kevoh:
Just kidding stupid me, just checked wifi sleep policy...changed it to 'never' now. Yeaaa that might've helped lol.
[Vibrant General] Yellow C6:
Switching to bionix 1.91 stock kernel solved my idle battery drain issue. I was losing ~4% an hour and now with bionix it's not draining. Unplugged the phone this morning at 100% and an hour later it was still at 100%. Same as before the JI6 update. I'm happy now. Bionix is smooth as butter.
[Vibrant General] kevoh:
I'm contemplating this option, how long have you been on bionix now? Any stats on batt performance afterward, hours?
[Vibrant General] natecglenn:
After the update I got horrible lag and bad drain. I'm talking 4 hours on average usage.
[Vibrant General] 12paq:
Does anyone else see the irony or possible logic that Samsung gave us a stronger modem that uses more power and a new task manager to monitor what else is running draining power with the Ji6 update? Granted there are better task managers for root, but kinda clicks in my head.

Also after all my settings have been checked, apps, wifi sleep (used OCLF), widgets and internet, syncing frequency, wallpaper etc. I used Rom Manager to recalibrate my batteries. I thought that the battery data might have been wiped during the update and at first my phone behaved like it.

All good now. I'll never have the stand by of a flip phone, but it all seems reasonable. I use my phone a lot, a real lot. I go through 2-3 charges a day, mostly 2. I have extra batteries also. Stand buy time almost seems better, but I have not recorded data and I have made many changes.

Theres a good thread a dude put up in the Vibrant general section about his anal battery saving habits, he uncovered more ideas and things I didn't know. Hes admitedly extreme put its a good read. Also a couple of threads on how to recal the battery, some disagreement there so I did not chime in here with specs.
[Vibrant General] Tarzanman:
Was completely stock with no real issues (GPS worked, even if it was a bit slow).

Upgraded to JI6 and now my battery life is horrible. About half a day (or a bit less) with normal use (which is one or two calls and maybe 3 mobile sites for me).

How disappointing. This might be the straw that breaks the camels back and pushes me over the edge for a custom ROM.

Samsung sucks. The only thing they are good at is making display screens.

This is ridiculous. No screen is worth 4 hours of talk time.

I am going to look very hard at the MyTouch HD when it comes out
[Vibrant General] rmeden:
it's the radio! (at least for me)

I live in a weak signal area. To improve battery life, I normally keep the radio at 2G (now "GSM") mode.

After the JI6 update, overnight (idle) sent from 10% to 40% (IIRC, but huge).

As suggested, I changed advanced WiFi settings to "sleep never", and overnight loss dropped to about 5%! So, I think it's the radio power.

The radio power is variable, so those not noticing increased drain are probably in a strong signal area.

[Vibrant General] kstar54:
My phone is rooted, but stock....unplugged less then 5 hours, battery totally dead with almost no use and no apps running.

Updated thru kies mini.

Mad....
[Vibrant General] presence06:
I'm going on 34hrs since yesterday. I've used it for calls, text, gps/foursquare, text and a bunch of pictures and email. I check the services and kill the stupid download manager for Media Hub and I get decent battery.

But where I work signal is variable, and my battery takes a hit but on a regular day I can get a full days work of use. It still could be better though.
[Vibrant General] kelkee:
how do you kill the download manager for media hub?
[Vibrant General] Ms_Vibrant:
I noticed that too.. so I had to stop the omadrmconfigservice blah blah... it is connected to media hub... i stopped those 2 on running services/manage application... andmy battery seems better :)... mine last up to0 18hours or more with moderate use..

as for the lag... the new Youtube widget is buggy it makes my phone hangs... not sure though but this is just my observation.. i've been looking for the old Youtube app version but I can't find it..

these are just mere observations..
[Vibrant General] chui101:
Try resetting your battery stats in Clockwork Recovery. I was experiencing significantly decreased battery life (JFD was ~16-20 hours with average use, JI6 was about 8-10 hours average use), but after doing a full charge overnight and then resetting battery stats, I was able to get a full day of use out of the phone today again.

I will try out bionix soon, though. I want to do a bit more research before I dive in though, to see what I'm getting myself into.
[Vibrant General] presence06:
How does this make battery life better? You're only removing the stats, not the "memory" of the battery.
[Vibrant General] Ms_Vibrant:
I stand corrected... i stopped the omadrmconfigservice blah on running services... not the DRMprotectedDRMprotected protected on manage application..

my bad... good thing I double checked... still, this is just an observation..
[Vibrant General] presence06:
Lol. I read your post and killed both the imadrm and the media downloader, I have been at 6% left for the past half hour now, thanks! lol.
[Vibrant General] Ms_Vibrant:
Hahahha I apologize... but hey just trying to help :)but I believe it's OK to kill those too coz those are for movies right? like like the avatar?
[Vibrant General] Ms_Vibrant:
Actually I read on android central about that media hub

​

being connected to omadrmconfigservice. Epic users were having huge battery drain since the media hub update... it was suggested to kill that on running services..

based on my observation, stopping media hub/download manager and omadrmconfigservice made my battery lasts longer..
[Vibrant General] presence06:
Yea, before I was just killing the media hub download manager, and the battery life would decline still pretty fast. Now that I'ved killed both the battery is steady for more than 15-20 minutes. So hopefully they won't restart themselves. Media hub should be optional and have the option to remove.. I for one will never use it.
[Vibrant General] boomerbubba:
That is good confirmation. And it does sometimes help to at least skim the comments higher in the thread. :)
[Vibrant General] sumasage:
How is your battery life now after killing those services? I am still running JDF so want to know if this is the fix for the battery drain. I wonder if we delete the Media Hub application would make it better.
[Vibrant General] heygrl:
I deleted Media Hub and things seem slightly better. I'm usually on WiFi (way less battery drain during intensive data transfer) unless I turn it off and forget to turn it back on so I can't say for sure.
[Vibrant General] presence06:
How did you delete it? Did you use titanium?
[Vibrant General] heygrl:
I used Super Manager. If you decide to keep it, disable the auto memory wipe stuff and any other automated services.
[Vibrant General] presence06:
I just rooted my Vibrant and installed Titanium Backup (Free version) and backed up and removed/uninstalled Media Hub. I'm pretty new to rooting, so me backing up is that just so If I want to reinstall it I could?
[Vibrant General] Shrivel:
I have seen so many posts about the poor battery life of JI6, and I am one of the handful of people that answered this poll saying that I believe I'm getting better battery now than I was prior to the update.

I did a non-scientific test today to truly test my battery's performance. The purpose of the test is not to say "all you folks that claim poor battery life are wrong" but instead to demonstrate that IT IS POSSIBLE TO GET GOOD, IF NOT EXCELLENT BATTERY LIFE FROM JI6.

I should first describe my typical usage pattern. I use my phone primarily for three purposes: voice calls, as a music/MP3/podcast player in my car and via headphones, and to read online forums and RSS feeds (mostly by apps). I drive a bunch traveling to client's homes and my office, and I am constantly using the phone for media while in the car and it is also usually plugged into my cigarette lighter adapter. It is highly unusual for my phone to fall much under 90% unless I am out all day long away from my car.

Today, I decided I was going to use my phone the typical way I do throughout the day, except I was not going to power it from my power adapter. At the end of the day I had the following results:

Time since unplugged: 8h 51m 53s

Percent left: 73%

During this 9 hr period, I USED my phone. In fact, I used it today slightly more than I would have in a typical day on voice calls. If I were to continue to use it at the same level, I could expect close to 36 hrs use before I would need to plug it in again.

So, what's my secret for such good (IMHO) battery life?

NOTHING.

Honestly, I do nothing special in order to obtain these results. My GPS is always on. 3G is always on. I don't run any task killers or Juice Defenders or any special software of the kind. My Gmail is set to auto-sync. Weatherbug is set to update every hour. The only thing out of the ordinary about my phone is 1) root and 2) the accurate battery mod. I've never "calibrated" my battery.

Now granted, my phone is not constantly stuck to my face and I'm not sending more than a handful of texts each day, but even if we factor in DOUBLE the usage I have, that would still amount to 15-18 hrs. of active use.

If you are only getting 3-4 hrs. of use from your phone, SOMETHING IS WRONG. A Vibrant is capable of good battery life.
[Vibrant General] nights62:
Ok, so its been a while since I started this thread, I have been following it over the past week and testing out things on my phone. I am convinced that I am seeing far worse battery performance on JI6 than I was before. I have two phones, one work phone(iPhone4) and one personal phone(Samsung Vibrant). During the work week I am usually on my work phone and not on the Vibrant very much. Before the update during a normal week I did not have to charge my phone until I got home, and I usually had plenty of power left. Over the course of this week I have run dead by around 9PM every night with very little use.

Yesterday I decided that I would reboot the phone disable media hub and the DRM service associated with it. Today it is now 9:30PM and I used the phone more than I have all week and my battery is at 28%. I realize this is not a scientific test, but either there is a random bug that has not effected me since my last reboot, or Media Hub and that DRM service is the culprit.

I do find it interesting that cell standby was the primary battery drain before I disabled the DRM service and Media hub, I wonder if this means that the new DRM service is pinging something out there on the net a lot, because media hub and this service do not even show up in the battery usage list.

Bottom line is I am pretty confused as to what is causing my battery woes, but what I do know for certain is my battery has been bad since JI6. I will keep media hub disabled this week and check back with you guys in a week or so to see if my battery continues to last longer.
[Vibrant General] moridinga:
I agree that something IS wrong, the question is what and how did the JI6 update cause it. After the update I get numbers like the following for the battery drain:

Cell standy: 58%

Phone Idle: 17%

Display: 16%

System: 5%

Angry Birds: 3%

Yes my wife was playing Angry Birds on the phone. Before the update, display would 60%. How the hell can cell standby now be 60%? Before the update, battery life was very reasonable and made sense (and we have never had issues with cell service). The phone is mostly at home, where we have wifi, so the cell data connection should be off most of the time.

Besides installing Angry Birds, nothing else changed on the phone except the update. Phone was rooted prior to the update, but I unrooted before performing the update and haven't re-rooted. Will messing with these DRM/MediaHub services change anything?
[Vibrant General] nights62:
Try killing media hub and the DRM service. It sounds like you are seeing the exact same problem as I am. Cell Standby for me was through the roof as well. If you get a chance kill those two services and run it for a few days and let us know if anything changes. For me after one day I have seen an improvement.
[Vibrant General] Shrivel:
The problem with that theory is that I have done neither of these things and am still getting excellent life from my battery. I did my "experiment" again yesterday and got similar results again. If I were to guess, something that you are doing and I am not is triggering those two services. Rather than disabling those services, we need to figure how why they get triggered for you and not for me.
