Hello guys!

I am using V10A stock ROM. Could somebody tell me advantages of this kernel compared to stock kernel 2.6.32.9?
[LG Optimus 2x] lws803:
+1. Yeah are there any benchmark changes and so on in this new kernel? Also are there any bugs in this kernel like browser lags or something?
[LG Optimus 2x] rwtt:
Hi,

Thanks for this Kernel, Cifs support changed my life ;)

However I sometimes have some big lags. Phone doesn't response for 30 secondes or more. Even sometimes i have to remove the battery to reboot.

I had not noticed this pb with original Kernel.

Am I the only one having this issue?

Is there a new version of this kernel available?

Thank you
[HTC Inspire 4G] bfrd:
First, I hope I am in the right spot. I am looking to get some help with a Bluetooth problem. I love the rom, but I am having some issues with bluetooth connectivity. I do not recall which radio I am using, nor do I know how to tell. The rooting process was somewhat of a blur.

Problem Details:

Bluetooth pairs with my car exactly as I would expect. Transfers the entire contact list to my car's internal phone book (after a security warning). This works perfectly (waaaaay better than my iPhone 3GS did). However, when I get in the car to leave, the bluetooth connection rarely happens. I get a connection failed. Sometimes I can manually re-connect, but lately I am having to reboot the phone. Once rebooted things usually work. I am also occasionally getting a Force Close on the "Phone" app when dialing from the car.

I first used attn1's hack kit and used the current CoreDroid which was 4.7. It had the same intermittent connect issues, so I updated to the latest version. This version actually seems like it could be a little worse.

Any suggestions? Please let me know what additional information you may need.

Thanks
[HTC Inspire 4G] anit77:
Hi bfrd,

Welcome to XDA.

Unfortunately this is not the right spot to post your question. What you should have done is searched the CoreDroid thread for the issue you're having and see if there is any info about the problem you are having. Here is a link to the search results for "Bluetooth" in that thread.

http://xdaforums.com/search.php?searchid=65753748

If you can't find what you're looking for via searching then post a question in that thread of the rom you are using. The Development sub-forum for any device is for Dev's to post or for the occasionally helpful instructional post. Otherwise you should post rom specific questions within the rom's thread and non rom questions in the General sub-forum.

Good luck with your problem and happy searching.

Hello all

The following post are on the frontpage of XDA today.

xdaforums.com/showthread.php?t=1010807

The hack is ment to increase the cashe size used for SD card reading and thus increase the overall performance of the phone (when it reads from the SD).

I noticed that this hack only affect the internal SD card on the Galaxy S phone and that the results aint that great as reported in the original post. I wonder if any one can make this hack for the external SD card, so we can test the effect. we might just have to change the value at

/sys/devices/virtual/bdi/179:8/read_ahead_kb

but I dont know how to test it since SD Tools seems to pick the internal at all time.

NOTICE: since this should only affect the read speed, I would ignore the results of the write speed (it might have some kind of effect, but I simply dont know).

Bias: It is also a fact that SD Tools seems to give different results if you run the tests continously (with the same amount of cashe) without closing SD Tools down, compared to Running one test, kill SD Tools, run a new test.

Tests

The avg score is what I

think

it is after looking at the test. It is not any number reported, since the score reported by SD tools is just the last read/write speed. I also ignore the vary high number at the start of the test, since it seems like an outlier.

128 kb cashe:

Write: Interval = [5 mb/s ; 40 MB/s]

Avg = 11 MB/s

Read: Interval = [8 mb/s ; 18 MB/s]

Avg = 11.4 MB/s

1024 kb cashe:

Write: Interval = [3.8 mb/s ; 20 MB/s]

Avg = 5 MB/s

Read: Interval = [15 mb/s ; 19 MB/s]

Avg = 18 MB/s

2048 kb cashe:

Write: Interval = [11 mb/s ; 40 MB/s]

Avg = 25 MB/s

Read: Interval = [15 mb/s ; 22 MB/s]

Avg = 17 MB/s

3074 kb cashe:

Write: Interval = [4 mb/s ; 20.5 MB/s]

Avg = 5 MB/s

Read: Interval = [10 mb/s ; 40 MB/s]

Avg = 20 MB/s

As you can see, the write speed on 2048 kb seems all wrong, but as said before, I ignore the write speed.

From this test, it seems like 1024 kb is just fine.

Feel free to comment and post your results.

Hey everyone,

I currently run CM7 off an SD but I was wondering if there are benefits to replacing the stock os on the emmc?

Are there any speed differences or technical pros to it?

Thanks for the input! This is a really fantastic forum!

sent from my nook color
[Nook Color General] pbcal:
From my experience the booting time is almost half if using emmc version. (SD card version ran on a class 4 card). After booting the performance is almost same. You may get better boot time for sd card using a class 6 or class 10 card.
[Nook Color General] JustusIV:
I dont have an answer for you as i picked mine up yesterday and decided to go the SD route at the start i am curious on this question myself.
[Nook Color General] joelszs:
Well from my experience, running from the SD card is very smooth... so for ease of use i highly recommend it for a first go.

I have a follow up question- for some reason my macbook recognizes the second partition of my sd card but my pc desktop does not. I am referring to the partition generated for storage by the CM7 installation process that allows storage on the data card simultaneously.

Any ideas why this would be?

sent from my nook color
[Nook Color General] rogerdugans:
I use Macs and Windows machines rarely (and I am guessing you run Windows on the desktop) but my guess is the ext4 partitioning that CM7 uses.

I seem to recall that working- at least somewhat- on Mac but not on Windows, but I am not positive.
[Nook Color General] dexx0008:
i chose sd, because it's super easy to backup my sd card as an image by popping it into my laptop. I can then burn that image back to a sd card if i want to try a new android build without messing up my default android install. I can always boot into the original nook os if i want as it is unmodified.

i used a class 2 and it was pretty slow. moving up to a class 6 and 10 has really helped and i don't notice any slowness.

i have not run off internal memory though so i don't have a baseline to compare.
[Nook Color General] nerdtaco:
eMMC is faster than my class 2 uSD cards, and it's easier to swa stuff back and forth from a computer/phone/camera/whatever with a removable uSD.
[Nook Color General] JRSly:
Cool, I've been wondering about this myself and was about to make this same thread.

I was concerned because I get a ton of force closes running off the SD, and I wondered if that was a problem that would be solved by going to eemc. Or if somehow I've made a mistake setting up my card and that's the issue. I'm very knew to this whole scene, so I'm still a bit scared of rooting at the moment and would love to iron out the problems I'm having with the SD booting. Things run fast, and fairly smoothly but eventually something will force close, like Market, and then Google Frameworks and then pretty much everything will refuse to run after I tap their icon. Forcing me to restart. Also, some things, trying to download new skins for Beautiful Widgets is impossible. Only get force closes.

I can't figure out if it's anything in particular that causes it to spiral out of control. And what makes it more annoying is this is my girlfriend's new Nook, I'm trying to get it set up for her to work as smoothly as possible. If it was just mine, I wouldn't be as bothered by messing around and trying different configurations and whatnot. But I know she won't be as patient and tolerant of these issues and won't want to keep bugging me with every problem that pops up.

Would you say this is likely a localized problem on my end through some fault of my own? From this thread, it seems people are having pretty great experiences with the SD method. Which might be reassuring. I think I'll do a backup and start from scratch this evening.
[Nook Color General] ax135:
@JRSly: What type of uSD card are you using. I was experiencing the same problems you had with booting, force close, refuse to run, thus a final restart. After swapping out four different types of uSD cards, SanDisk (class 2 and 4), A-DATA (class 6), Patriot (class10), I finally deteremined that the Nook is very picky about the type of card. All the cards work fine in my digital camera or PCs, but the A-DATA and Patriot are slow and often hang in the Nook. I am now using the three Sandisk cards with no problem. I recently updated to Nookie Froyo 6.8.5 and it runs great on the SanDisk cards. Just for the test if it will run faster on A-Data (class 6), wouldn't you know it starts to hang and FC just like before. I guess I'll use the A-Data card in my digicam. Try a Sandisk card and see what happens. I even try one of my old Sandisk 2GB card from my Blackberry which is unmarked but has a class 10 performance when measured.
[Nook Color General] BlizzofOZ:
I'm very new to this... and I keep seeing emmc.

What is this? Internal memory?
[Nook Color General] JRSly:
I feared that this might be a possibility too. My first attempts were with a little 2Gb card I'd had lying around and it didn't work very well at all. I couldn't get past installing Gapps for all the force closes. The next day I went to Target to get a larger 8 Gb one so I could also play around with Honeycomb, it's a Class 6 Lexar card. I started over last night and tried a couple of attempts at wiping and burning the image and inevitably ran into the same problems. It looks like a crummy(at least in terms of what the Nook likes) card is a distinct possibility. I'll give Sandisk a shot.
[Nook Color General] xdabr:
Yup. (I didn't get it either.) :)

Since MMC is a sibling of SD cards, it's basically dedicated internal SD storage with a controller.

http://en.wikipedia.org/wiki/MultiMediaCard#eMMC
[Nook Color General] rogerdugans:
You got it in one. :)

sd card is self explanatory, of course, and emmc is the internal memory of the NC.

The only DISADVANTAGE to running on emmc is that you lose the stock B&N version of Android.

Other than that- it boots a bit faster, may run a bit faster and be less likely to have force closes and similar problems.
[Nook Color General] BlizzofOZ:
That's what I thought!

Thanks for the cofirmation :o
[Quantum General] danix:
While the unlock works as described and I can deploy applications on the phone I cannot debug from Visual studio. The application deploys and it can be manually run but I cannot debug. The following error displays when I hit F5

---------------------------

Microsoft Visual Studio

---------------------------

The application could not be launched for debugging. Ensure that the target device screen is unlocked and that the application is installed.

---------------------------

OK

---------------------------

Any ideas would be appreciated, I've tryied pretty much everything so far including a clean install of the latest VS + WP7 sdk and a factory reset of the phone.
[Quantum General] KiwiGeek:
Same here

I have the same issue with debugging that you do. The only way I've managed to resolve it was restoring to a pre NoDo backup, unlocking with Chevron and then updating to NoDo again. I can only guess that Chevron must do more than change that one registry key (or rather, that the phone does more than change that key when it's told by chevron to unlock) but unless we can figure out what that extra step is we're probably stuck.
[Quantum General] jlott069:
Your Problem

Well, that is your problem right there, lol. Both of you mentioned using Chevron to unlock. If you are using Chevron to unlock, AND using MFG, well, chances are ur pissing it off somewhere. dont use both. MFG makes it so that you DO NOT NEED chevron with the LG Quantum, not to unlock. and everything else works just fine - the chevron ringtone thing, ect. Thats probably where ur extra step is... ur unlocking it two different ways and making it upset.
[Quantum General] danix:
No Chevron in my case, I've only used the MFG on a NoDo updated phone. I don't think you can debug using only these registry keys. There is something else. :(
[Quantum General] jlott069:
have you tried actually calling LG and talkin to tech support? I honestly cant think of anything myself... and ive been thinkin about it and working on it since it was brought to my attention. Its LG's software, they should know something.
[Quantum General] Steven855:
I guess you could try a hard reset to see if anything happens
[Quantum General] derausgewanderte:
thanks for putting this up here. I've discovered this as well a while back and still find a lot of people with LGs that are being told to roll back or reset their phones after they got their NoDo in the WP7 forums. Many people believe what doesn't work with their device applies to all devices. Luckily for us LG included the registry editor right on the device ;)

Your title should include that this works after NoDo and it should be made a sticky!

cheers

I have tried this several times but my phone still shows the following error when I use a SIM other than AT&T:

"This SIM card can only be used on specific networks. Contact your service center for the unlock code"

Any ideas on solving this would be appreciated

And does the "debranding hack" remove the AT&T boot screen?
[Quantum General] surrender420:
-FIXED- Seems in my triple checking wasn't thorough enough, for the path's I was including "\" before the path and the whole string was showing HKEY_LOCAL_MACHINE\\ (the \\ being my issue) just fyi for any other spacey people X)

I attempted the registry hacks to unlock, keep unlocked, and change app limit on my post NoDo AT&T quantum and triple checked my registry after connecting to my x64 win7 ultimate machine and trying to load my chevron prepared ringtone. With most package loaders I get an error of an app limit but I believe with Tom's XAP installer along with the chevron unlocking tool I tried after realizing the registry hack didn't work, I get a phone not detected error when it is clearly shown in Zune which I have open during the whole process. Could it be nodo interfering or an issue within windows? Should I try a restore and chevron post nodo? The debranding isn't required for the unlock to have an effect is it? Any advice would be appreciated as I get bored with these ringtones!

-Update: Error received when attempting to deploy XAP to device using Windows Phone Development Tools Application Deployment.

Error - Unable to install application. The maximum number of developer applications on this phone has been reached. Please uninstall a developer application and try again.

-Note: I have never been ABLE to install a developer application so I don't think it's possible I have any to uninstall. I have changed the app limit registry key and it seems to have no effect, unless the problem is that my phone isn't unlocked, would I get the same error if that were the issue? It is possible to unlock post NoDo with MFG right? Wish i could figure out how ... :confused:

When attempting with Tom's XAP installer it says Make sure your phone is unlocked, make sure you've connected device to pc and zune launched.

Seems to me the phone just isn't unlocking...

Is it possible to rollback to pre nodo amd attempt? would it better my odds?
[Quantum General] jlott069:
its not removing the subsidiary lock from the phone. you are misunderstanding the information. when it debrands, the provider no longer has control over whether or not you get updates and such. the debrand does not remove the logo. check around, im sure someone has figured out how to do that. as far as the unlock goes, it is simply allowing sideloading. not moving over to another carrier. basically you are changing the code to a devel code. if you want to unlock, well i doubt it if that can be done just yet. check around, i might be wrong. but i know that the carriers are not going to release the unlock codes yet, but call your carrier, u might get lucky.
[Quantum General] jlott069:
as far as the app limit change goes, the only devices i am aware of that working on at the moment is HTC, but that is only for sideloaded apps. debranding isint required for the unlock to work, but that still does not matter. at the moment, my understanding is that pre and post nodo there is a 10 sideload app limit on all LG devices. the HTC code may differ slightly for whatever reason. your problem is that is just is not possible to do more. when your computer says it needs to be unlocked, it is ALSO talking about your screen, not just the phone. if you are doing something like sideloading ringtones, remember, u can load them, then remove the app that installed them. uninstall, then reload, that way you dont end up filling it up. a developer app is anything you are attempting to sideload. anything you are not getting from the marketplace. it IS possible to unlock post no-do. sounds like u just have too many sideloaded apps. remove some, then try. and make sure your phone is on the start screen.
[Quantum General] jlott069:
oh, and I would put the reference, accept that wasnt where I found it. I cant remember where I got all of it, thats why I apoligised for reposting anyones info.

Another useful registry key: Allow max number of unsigned apps

[HKEY_LOCAL_MACHINE\Software\Microsoft\DeviceReg\Install]
"MaxUnsignedApp"=dword:7fffffff
[Quantum General] surrender420:
jlott069, problem was i wasn't able to sideload any apps, so i couldnt have had too many installed. but problem resolved, thanks for the advice!
[Quantum General] surrender420:
Now this is just crazy, reflashed my phone. and i hgot all the updates again, now i'm trying to unlock it and once again am having the same issues.... seems like it isn't unlocked after changing the registry keys

-fixed after resetting to factory defaults and trying just the unlock key, i think it has issues trying to do the unlock and 2 keep-unlock keys at the same time

Another odd thing i notcied and i'm not sure what causes it, but either after unlocking my phone or installing touchxperience, i lose the capability to browse the memory via USB mass storage (zune registry hack)
[Quantum General] jlott069:
I still have that option, but I dont use touch experience, and i just still have it unlocked. I had to re-unlock it after my update to mango? I dont know why... but it unlocked just fine and im side-loading apps again with no problem. maybe the issue is in the zune registry hack? I duno...
[Quantum General] derausgewanderte:
happened to me too when going from NoDo to Mango it was locked even though relock was disabled. I think it's normal and it will stay unlocked if you followed the known steps.

cheers
[Quantum General] phihung07:
so after i install mango i think to relock again, will this process still work for the offical mango, thanks
