No video after kernel update? - myTouch 4G Q&A, Help & Troubleshooting

Strange problem I have been having... I have been running RG 2.1 for a long time with ckisgen 1.4 kernel for a long time and recently my battery life started to suck.
I flashed to 2.0 an was getting way better battery life but noticed that I couldn't play any videos (youtube, flash, even ones i took with the cam). So I restored to the backup I made and the videos were back.
Decided to try a completely different kernel today and the results were the same.
So I am back to the 1.4 kernel and crappy battery but at least I have video... Any ideas?

Advice on going from 2.2.2 back to 2.2.1

Hi,
ever since last week when I updated to 2.2.2, my battery life has been crap. In the half hour it takes me to get ready and drive into work, the battery goes down to 60%. with 2.2.1 it was like 98% so something is messed up.
Nothing else has changed, no new apps.
I did the froyo update manually so I sort of know the mechanics of the process but I'm just wondering if I need to go back to stock and then to froyo and then the updates or if I can just download the 2.2.1 image and update with it.
thanks,
I have the same problem :/
Obvious answer but have you tried a factory reset? I would take a stab at it before using more aggressive solutions.
Failing that you can flash a stock rom using the passimg.zip method and OTA back up but at some point you will be back on 2.2.1 and getting nagged to update to 2.2.2 again.*
*It could be that i'm using the European varient of the firmware but i've not had the best of luck flashing back to older versions (It's a long story). Suffice it to say, every method failed at some stage so i flashed a 2.2.2 stock/custom ROM instead.
I'm getting consistent 20hrs+ to 30% running CM7 nightly. Can understand wanting to keep it simply stock and CM7 is pre alpha but my battery performance is about double.

Did I understand you correctly? You could only get 10 hours of your battery on stock rom?! And is there really a positive difference in CM7 battery performance? I know that some people (including me) had problems with that on CM6 so in my eyes CM is not the most battery efficient rom. Just curious..
About OP's battery problem. My N1 no different than before 2.2.2 update. Battery life seems the same. +1 for factory reset.
Cheers!
it could be time to root and go cutom
I had the same problem
And found out that it was google syncing (which i could not fix whatever i did). I wiped everything and started again.
This fixed it, however here are some tips to get good life on the nexus.
(This worked for me and saw my nexus 1 last 1.5 - 2 days before getting to 30%)
1: goto dial pad and do the *#*#info#*#* under phone set it from WCDMA to GSM perfered
2: Always use wifi where you can, wifi uses less battery than 3G, (this was a major saving in battery power for me) Set your wifi to always on (even when the screen is off). The 2 main places you spend most of your time is at home and work, set it up for those places and you will see your battery lasting a crap load
(my battery went from a drain of 7% a hour down to 2-3% by doing this).

Thanks XDA

I want to start off by saying that I am a NOOB at this rooting and custom ROM stuff. I was getting ready to toss this Vibrant in the trash when I said to read up on rooting, follow the steps provided, and install a custom rom. XDA you have saved my phone. I want to thank all of you who provide all of the support here. I installed Bionix 1.3 and I am in shock at this phone now. GPS actually works in real time. The phone is superfast as well. The only issue I have is that I can't surf the web or check FB without my battery draining like 3-5% in a ten minute span. Its crazy. Battery does well in standby mode. Extremely well as a matter of fact. not sure why it drains so quickly when I actually use it. I have wiped the battery stats and done the battery cycle. Overall still love the new look. Keep em coming.
Glad you found a new appreciation for your phone through xda. As we all did.
Your issue is with the kernal used in 1.3. The OverStock kernel. I've had the same issue. Great life in standby 1% an hour vs on a vanilla kernel + voodoo 3-4% an hour drain. Whenever I have my screen on battery drain is insane. 30% increase with the screen on vs how it norally would be. I would recommend flashing ka7/kb1 + voodoo kernel. That should fix it right up.
2 things
Check and make sure there are not background apps engaged when using those apps (sounds like there may be)
Also if you want you can buy a 4g battery it is 1650 mah that will help. But I use my phone alot and Battery really not an issue anymore.
check your background apps see what is not necessary to run.
i believe Team Whiskey removed the OverStock kernel and replaced it with the regualar VooDoo kernel in Bionix-V 1.3.1....
Maybe you should try that....
I'm using Categorically Worthless kernel on Binix-V 1.3.1 and my battery life is great
I must say THANKS as well. Tried rooting yesterday but something went wrong, was on official 2.2 and couldn't get 3e-2e fix to work. Nearly bricked phone. Searched xda. Now rooted with Bionix v (not tw version). Loving this speed. Battery isn't an issue since I have a spare w/charger.

Go to team whiskey's website,register,go to forums look for shory's files near top of page download kb1+voodoo kernal and flash it w/clockwork ...that will overwrite the over clock kernal and give you much better battery life or you can just flash bionix 1.3.1,personaly i like 1.3 and i just switch back and forth between kb1 and overstock it only takes about 20 seconds to flash
Bionix-V 1.3 w/a Splash of Color
Thanks for the response everyone. Will flashing the kernel wipe everything? I will be doing a backup though clockwork anyway. I was just wondering..... Thanks.

No, it will just overwrite the kernal files, so your sd card and all that should be fine, but go ahead and get in the habit of making backups regularly. Trust me, it can happen.

Thanks SamSprint! (words I thought I'd never say)

So, I don't post too often, but I lurk a lot and like to think I'm pretty experienced with different ROMs. I've used Midnight, ACE, Bonsai, Frankenstein, and a few others. All of them pretty great in their own way. The devs involved are dedicated and brilliant and when you think of the base they were working from, they did nothing short of dark magic. I can't wait to see what they do with this amazing release.
Today, I'm officially back to (rooted) stock. Here's why:
The things I look for in a ROM are battery life, speed, and stability. I think that's a pretty standard list for your average XDA member. EF02 meets and exceeds every item on that list.
First for foremost is battery life. I see that some users are reporting atrocious battery life and some (like me) amazingly (ridiculously good!) battery life. I've been using the phone almost non-stop for 5.5 hours now and I'm still at 58%. That's with some netflix, Rdio streaming, calls, tons of txts, Doggcatcher through the main speaker at full volume, and endless configuration, installs, and tweaking. I'm coming from Bonsai which has some pretty amazing battery life, but it's (seemingly) geared more towards "standby" battery endurance and always drained quickly when I was using my phone a lot. I thought this might be a fluke, but I've rebooted twice now and battery stayed within 2%. All I did was plug in over night and ran battery calibration (the market app) this morning.
Other than that, everything just WORKS. GPS locks stupid fast (after clearing a-data state). 3g/4g. Almost no FCs. Wi-Fi doesn't disconnect. No volume stuttering. No bluetooth weirdness. Nada. It just WORKS!
I was playing asphault, Backbreaker football, and recording HD video today, everything was snappy and flawless. When you consider it's RFS, stock speeds, with bloat and no governor or scheduler tweaks I really am in awe of what the Epic has under the hood and how solid SamSprint have made this.
There's been a lot of contention about how to apply this. There's a flashable rooted/deoxed version out now, but just by nature of that install procedure, I think you're best to use Odin to flash the EF02 tar and then the CWM tar and then flash the su in recovery. Those are the steps I did and I'm running rock solid.
My setup:
EF02 Odin'd
Launcher Pro w/ twitter and gmail widgets (although TW was feeling great when I was tweaking the phone)
Rdio widget
Data and background sync enabled
Screen timeout 30 seconds
Wi-Fi on most the time
SwiftKey (although the new Swype is pretty great)
PS I flashed the zip version last night and had endless issues. Battery heat, no GPS, no audio, wonky data, and eventually a boot loop of death. Odin the way I described above got rid of all the issues.
Ya. Samsung... Thnx u skanky sweaty hog! U pissed with off with the delay on froyo. But u made it up with ginger. I was already convinced froyo would be the end. So thxs u hor.

I have to agree. I followed the OP steps myself as soon as it launched. I am debating on flashing the kernel out but will wait till something else is out. I prefer more app space so staying on odex for now. I have been removing bloat apps that I dont want slowly to ensure nothing is acting funny. I didn't have to clear agps o nothing for my gps to work properly with that set up. I am running ef10 modem.

Felt like sharing my experience..

Anyone running stock ec05 with the geno kernel? Decided to do this a few days ago. Despite the rfs, overclocked at 1.4 stable is giving me the best experience I've had yet. Also ran titanium backup and froze every piece of crap I found. My battery is amazing. Just yesterday I went 26 hours. For stock that's pwnage. Everything is extremely stable. Xda is the number one force closing app for me and it hasn't happened once. Everything is speedy and snappy even with rfs. And I dunno if its me but custom epic roms seem to screw up gpu drivers somewhere. Dungeon defenders is running better than it ever has at a smooth 40 plus fps. Scoring a 1300 in quadrant, 2700 in antutu. Here's my smartbench 2010 for kicks ) cheers lentlemen.
also found this weird battery snapshot I took of ef02 or something last week.

Roms aren't the answer for everyone. I kicked around going stock myself but the grip of the rom is too strong. I have been running the Urban Fury series' from CompKid and SRF 1.x.x. Haven't ran 1.2 yet and I doubt I will. Just doesn't have anything over 1.1 that I would want.
1.4 OC is very nice.
I have a similar experience with the GPU. Even though custom roms would give me better bench scores and overall snappiness, I'd get noticable lag and choppiness in some games. I've been back to stock for a while now and it pretty much runs every app smoothly. The Gingerbread leak was silky smooth and snappy, but after a while random reboots made me go back to Froyo. Between the game lag and clicks/pops I'd get in music playback with voodoo, stock has been the best for me even though there are several things I liked about a couple of the customs. I may have to give genocide another go around by itself rather than paired with a rom to see how it goes.
Ever since I nailed down what was draining my phone over wifi, I get excellent battery on stock. Went 30+ hours the other day with about an hour or so of display time on, and still had 25% left before I plugged it in. Most of the battery issues with this phone (from my experience anyway) is simply the phone not going into deep sleep properly, whether it's an app or in my case, something on wifi network. I have things like LP Facebook widget and weather syncs set to 3 hours.

What was draining your mini nuke over wifi?? Also app freezing is the ****. All drm and **** that drains my battery while in sleep mode is gone. Going to power cycle the battery and then give it a test run with the [email protected] 1.3 and 1.4 are awesome but require overvolting. Trying to go for amazing battery life here. Also running the phone @600MHz Compared to 1GHz you barely notice a difference.

Starburst ROM + Pershoot's 1.4ghz Kernel Stats

Hello, Just thought I would post my stats using the new Starburst rom with Pershoot's Kernel. Getting great speed and the system runs very smooth but it feels like my battery is draining quite abit faster...
I have setcpu set as "OnDemand" 300mhz-1400, 256mhz when screen is off. Is this battery drain normal? Ran for 4 hours idle while working, then during break i used my tablet for about 15 min, idle another 4 hours and then after work I only got about 2 1/2 hours of use from my tablet before getting the 15% battery warning (79% to 15% in two and a half hours).
Before installing any TW rom and using Pershoot's older (non-TW) kernel with same settings I was getting atleast 4 hours after having the system idle all day while i work (10 hrs), this was with about 40%+ battery left to spare. Please take a look at my stats and feel free to give any suggestions to help me get more battery
The performance now is very good, but before TW i was getting about 150 less points in quadrant (2950ish)with the extra battery life. Also i dont let any apps run wild while idle and have gps,bluetooth,wifi turned off during working hours.
Quadrant Score, Starburst TW + Pershoot's Kernel Aug/9/2011 builds (score:3100).

Battery Stats, notice the steep drop at the end? Thats the only time I really used my tablet... about 2 1/2 hours, web surfing (14 hours 35min total on battery).

why is your screen on and awake bar completely full if you only used it for the last 2:30?
In GENERAL
Screen on time 8-10 hours
Standby time ~100-500 hours depending on whats on/apps installed.
No idea why it says the screen was on, it was not... And I had the unit on but as far as i know there isn't a sleep option so the unit was awake but not being used.
If you know of a sleep option please let me know, thanks for your reply
Yeah I'm still testing this exact rom/kernel combo and there is something up with it.
On a reboot, does the battery level go up? Does it stay up for a little while then drop back down?
Also have you done a battery calibration? If so, how?
I'm just trying to narrow down what could be causing the problem. I'm no dev by any stretch of the imagination, but for some reason I really want to find out what is causing this. It doesnt seem to affect all machines so in finding the simularities of those that are having this issue, we can squash this bug....
I was using this combo and my google music kept force closing.

it should goto sleep automatically, and if screen was off it should be indicated as off. maybe something is wrong. im currently on pershoot's kernel as well and have had some issues with battery calibration (reporting bogus stats).
i think pershoot is looking into the issues on his thread.
im using 10.1-Wifi, Touchwiz UX (OTA, GT-P7510)
It's a kernel problem. Try going back to stock or an older version of pershoots.
It'll be fixed today from what I've read.
Late last night reinstalled Starburst with its original rom, after my 10 hour work day it still has 95% battery left (after some galaxy on fire 2 during my break), hella lot better than it was yesterday.
I will wait for Pershoot's revised kernel and test it out again. And thanks again for all the devs making custom roms and kernels! Much love to ya! <3
*Stock Starburst kernel is showing my screen being off (when it is off) and my system as not awake when screen is off under battery usage in settings

From what I've read, he claims there is no problem with the kernel, the problem is with the user. We havent calibrated the battery correctly according to pershoot himself. Problem is, I cant figure out the secret to a correct calibration process....

Flash Starburst or stock rom then charge your tablet 100%, once your battery is fully charged flash Pershoot's kernel.
I have not tried this myself but from what I have read it works, right now im happy with the performance on stock Starburst kernel, quadrant is at 2300 compared to Pershoot's 3100 but its running so smooth I cannot notice the difference. Going to wait for Pershoot's reworked kernel and then flash it, I gots to have my voodoo!
Update:
Today I reset my battery, and installed Pershoot's kernel. I'm still getting battery drain, used for 5 min this morning and its down to 80% (just browsing web)... Also my clock got stuck at around 5:08am and my alarm did not work this morning until i turned my screen on. After I installed Pershoots kernel alot of apps were acting up and not running properly but after a reboot my clock and apps started working as normal.
And I have to hit/hold the power button like 5 times to turn on the unit now. Going back to original Starburst for now.

Darn. I was just about to give this a try. Oh well I'll try it anyways, nothing to lose. Just remember all the issues that may or may not be caused by the kernel is actually user error
Did anyone try the newest version of the kernel? Posted 19/aug/2011.

I'm using it now & it's a very good finish product. His last version gave me battery issues like no other. I believe he withdrew it after numerous complaints over battery issues.
Working great.
I always wipe Dalvik and Cache before flashing the new kernel.

sorry for the noob question but what does dalvik and cache contain?
Edit: Nvrmind. Found out my answer. I shall do this the next round of installing kernel
