It depends on the type of update, some are full updates which will wipe your phone (including removing root), some are incremental which will just replace some system files.

You can find out which though by going through the update process. If the uprade will wipe your phone you will get a warning stating so.

As for you wanting to go back to stock, you can simply download a stock rom from here on XDA, flash with smartflash, and you will be back to completely stock.

[LG Optimus 2x] Mr.Greg:
Thanx for reply. I downloaded stock rom and smartflash, but I don`t now exactly how do that... I open smartflash, click rom copy d/l, then in cp bin browse to find stock rom file, to drag in, but when i click browse in that map where the stock rom is, smartflash don`t see this file.. any idea????

Hi guys,

I just decided to install Honeycomb on my Nook's emmc, but I haven't played with it, other than the fact that the Market's fails whenever I try to install any app?? Any way to get around that? Any link to the newest HC release?

Also I was wondering if the newly released HC 3.2 (On Huawei Tab) may be of any help to the community, being that it is supposedly optimized for 7" tablets.

Thanks guys for you responses, Also a shout-out to Deeper-blue, Divine_madcat and all the devs who are making these ROMS available.
[Nook Color General] Divine_Madcat:
In terms of hardware compatibility, i do not see 3.2 being much help. While the Hauwei tablet is not a Tegra 2 cpu, it is still not the same CPU family as ours, making it still such that we could not port it.

The SDK might be more useful, but i am not too optimistic about that either.

One thing it would fix, is having to use 120 DPI on our nooks. Since that build would be compiled for screens like ours, a more natural setting of 160 DPI should be feasible.
[Nook Color General] s9pa:
That is a bummer :-( I was hoping that the HC on Huawei was going to be helpful. Well, what is the best HC (less buggy) that is currently available for Nook Color. Any link to the download would be appreciated.

Thanks

Hi,

Anyone know how to get the earphone volume increased on the galaxy S2.

I have read some posts which have samsung service codes, but when running them it says "invalid code".

Anyone know what code I need to turn the earphone volume up ?

Lots of posts but no one seems to have nailed it for GS2.

I concur. Volume level is too low even at max volume. Using my car's AUX jack, I only need VOL 30 with my iPhone 4 at max volume. I have to turn up to VOL 40 to get the same volume with the SGS2 at max volume. (2008 Mazdaspeed 3).

The code is a nice start, but not sure where to go from there.

[Galaxy S II Q&A, Help & Troubleshooting] Extreme184X:
this problem is not only a headset problem, its a over all volume issue (most importantly handset) I have that problem too, here is three possible solutions that worked for me, and "MIGHT" work for you.

Give these a try and be sure to give a feedback whether it works for you or not:

A) Enter service mode by typing below code on your dialer :

*#*#197328640#*#*

click the following:

[5] AUDIO

[1] NB (VOICE CALL)

Choose Handset, headset, Speaker (which ever you want higher volume)

[1] VOLUME

[1] SRC Speech RX Volume

Change default values and higher the values any number of your choosing, here is an example:

[0]0_lvl : 68

[1]1_lvl : 72

[2]2_lvl : 76

[3]3_lvl : 80

[4]4_lvl : 84

[5]5_lvl : 88 Higher these values to until hear volume improvement.

Can also edit the values from:

[2]DST I2S1 TX Volume

[3]SRC I2S1 RX Volume: 100

[4]DST Speech TX Volume: 94

This is Samsung volume setting, worked for several people but sadly only worked 2 times for me and values keep resetting for me (doesn't mean for you, so give it a try) Also this is based on STOCK firmware.

B) the second thing you might to try is app called Volume+:

http://androidaudiohacks.com/home/vo...bread/download

This app guarantees it higher the volume without the need of touching its default settings, BUT huge drawback it highers everything: Headset, speaker and Bluetooth EXCEPT HANDSET which is the most important :-(

(I also downloaded many volume increase apps, but Volume+ was the only one got the job done for everything but handset)

C) Lastly get GOOGLE VOICE app (create a GV account if you don't have one)

https://market.android.com/details?id=com.google.android.apps.googlevoice&feature=search_result

just by installing Google and logging on, every time you make a call, your calls get forwarded through Google voice and volume levels become acceptable in ALL HANDSET, HEADSET, SPEAKER, BLUETOOTH (just like phone should of have been) (this what i personally use fix my volume issues)

Hope one of these work for you.
[Galaxy S II Q&A, Help & Troubleshooting] marzocchi84:
hi thanks for the suggestions!

i'm on KF1 and lightning rom (rooted). Volume+ didnt work for me.

i tried method A and it works!(for headset and speaker, sorry didnt try handset)

No distortion at max. volume. Not sure if the settings will reset but I will monitor for a few days.

Below are my settings for reference:

Headset

[0]0_lvl : 72

[1]1_lvl : 76

[2]2_lvl : 80

[3]3_lvl : 84

[4]4_lvl : 87

[5]5_lvl : 92

Speaker

[0]0_lvl : 77

[1]1_lvl : 81

[2]2_lvl : 84

[3]3_lvl : 89

[4]4_lvl : 92

[5]5_lvl : 95

[Galaxy S II Q&A, Help & Troubleshooting] zaczek:
My workaround

I didn't want to play around with the service codes (the smartphone is supposed to be easy to use, it's not a text console). I noticed that when you plug in headphones, the sound level for media is decreased by half. For some reason, this impacts the level of conversation sound (this must be a bug).

I have worked around the problem with an app called Volume Locker. I simply lock the media volume to the max. It prevents a change in volume when you insert headphones. Of course, this is not suitable if you listen to music on your phone. I don't, so it's fine for me.

Hope this helps a bit.

[Galaxy S II Q&A, Help & Troubleshooting] furetcn:
I thought i'd keep this thread alive, since the issue with the S2 is still not fixed (currently owning an i9100).With the advent of the "S3" coming out one might think it is not important, but seeing the amount of S2 users out there I believe it is still relevant.

I tried all possible fixes I could find on the net and tinkered myself a bit.

What I can say about VOLUME+ (the app) is that it DOES boost pretty much everything, and it does all you want it to do, however, it does NOT manage to boost my headphones IN-CALL. And in the end, since the SGS2 is a phone above all, that what is most important to me.

The post on the first page with the service code *#197328640# is spot on though. It does STILL work for me on i9100 with ICS-XXLPH rooted.

The flipside of this fix is that it resets on every boot.

Currently i have not rebooted the phone for over 10 days and the settings have not reverted yet. So it appears to be on boot only.

Even though I have programming experience, I have never looked into developing apps for mobile phones, so here is my questions to people with more experience than I:

Would it not be possible to write an app that accesses the same data that is accessed through that service code, on boot, so that it would basically be set on boot to the user's desired value?

If there is such an app, what's the name?

If there isn't, is it possible to do? I'd be happy to give it a shot, however, if people tell me it is not possible, then there's no point in me scratching off the rust from my Java days to get into it.

Thanks in advance...

Low volume Galaxy S2 with original Headset

I think I have a perfect solution and explanation for low headset volume with original Samsung Galaxy S2 headphones.

At first I entered in to service mode and set the volume setting. I got so far that I had to do the hard reset back to factory settings and I had to load all my applications again.

As my father used to say” all good things are simple” that how is my solution to this problem and you will be amazed.

First of all the amplifier in galaxy S2 has high impedance (32 ohm) so headphones have to be 32 ohm (in case you would like to by a new pair).

But if you have an issue with original headphones, here is the explanation and the solution:

Take of the rubber parts from the earphones. If you have a close look you will notice that the chromium-plated parts are being peeled. These small particles are then attracted by earphones magnet into the exit hole of headphones. There is a net in the exit that catches this small chromium parts and block the exit.

Solution:

1 First brush of (use something sharp) all the chromium-plated parts to the plastic surface.

2 Remove the round net in the headphone exit (use tooth peek). It will come of easily. Use cotton stick that you use for cleaning ears and clean the exit headphones hole.

3 Plug in you head phones and you’ll be amazed.

Hope you’ll find this helpful 

[Galaxy S II Q&A, Help & Troubleshooting] stlior:
The solution is here!

So here's my contribution to the community:

First, two facts:

1) Audio menu is dependent on MODEM version (not kernel or android version)

2) (Almost) any modem version can work with any kernel or android version

Thus, the solution is to install a Gingerbeard modem (for example KE4). I did it yesterday, reception is the same and the audio menu reappeared!

Tested it today - talked using my headset (at volume of 100) and it worked like a charm :)

Enjoy!!!
