[Barnes & Noble Nook Tablet] Harvick_29:
First, I'd like to say a huge thanks to the developers on XDA for everything you've done for my wife's new Nook Tablet and my old HTC Hero CDMA that's now running ICS (you rock jaybob)!

You guys are all awesome!

:D

On to my problems...

First, rooted the wife's Nook Tablet, did the partial debloat (worked flawlessly Indirect, after I fixed a driver issue on my end...had to uninstall it and grab it to install the proper drivers before it installed the usb mass storage device driver, otherwise ADB wouldn't see it).

All the B&N stuff is there and using Go Launcher on the "android" side. Here's my first issue...some menus (Beautiful Widgets & Astro File Manager to name a few) and a few other random apps have white text on the menu making it essentially impossible to read what that option is. I played around a little with the Go Launcher settings, but can't find anything to darken the text. Does anyone know how to fix this?

Second, wife doesn't like the stock android keyboard because each letter you press the preview of that character pops up right above it. I know it's a throwback to when you had small screens and it's just a confirmation of the letter your pressing, but she finds it very distracting (I don't even notice it! heh heh) Tried installing other keyboards but since there's no way to go to the stock android settings (only goes to nook settings), I can't enable the keyboards. I tried going to the nook hidden settings and selecting a new keyboard from there, but only the "android keyboard" shows up, not the other couple I tried installing.

Last, is there any way to bring up the stock android settings options?

Swore I'd never say this to keep like sounding like a noob instead of just a lurker, but I looked around the forums and didn't see any questions that addressed my "problems" ...so if there are answers to these somewhere, a link would be appreciated.

I have the feeling these are issues that can't be fixed until get access to the bootloader/recovery and get the ability to cook custom ROMs.

Thanks in advance for the help!

The stock android settings menu doesn't exist. Try using the Hidden Settings app to get to the most common settings.
[Barnes & Noble Nook Tablet] Harvick_29:
Ahh...that explains it...was looking in the wrong forum! lol I think I was searching my HTC Hero forum since that's where I default to. :) The keyboard fix worked. Gonna try the menu thing later after I finish reading all the posts.
[HTC Sensation] strabo100:
I flashed AHRD 5.01 and later flashed back to AHRD 3.19 and now my computer will not recognize the phone. It keeps on saying unknown device and unrecognized device. I tried installing the newest HTC sync and driver but still won't work.

I've tried different USB port, and also on my laptop and neither PC will recognize the phone.

I have HTC BMP USB Driver ver. 1.0.5375 and HTC Driver Installer 3.0.0.017

wrong board. can a mod move this to Q&A?
[HTC Sensation] jasminthoria:
Try using different DATA CABLE. if there is fault in your data cable it will not recognize. Other thing you can do is connect your phone to your PC then boot in to bootloader skin there are chance your PC will recognise android phone by generic driver.
[HTC Sensation] strabo100:
thanks that works...wierd, I've been using the other cable for a few months. So what is a good place to get good and CHEAP cables.

Don't wanna pay 9.99 for a micro USB cable >__<
[HTC Sensation] jasminthoria:
You can use NOKIA micro usb cable it will work for sure.
[Optimus One, P500, V General] MaKTaiL:
Hi guys. Lately my mom's Galaxy S2 was losing service all the time and we had to reboot to make it work again. One day it stopped completely and it did not want to go back.

I searched for this problem on XDA and I found a pretty interesting fix that happens to work on ALL Android devices. That's why I'm posting it here, since P500 is my phone.

Since I flashed CM 7.2.0 A4 I've been losing service for a few seconds and getting it back with 2G data only. It was becoming quite annoying so I decided to use the fix I used on Galaxy S2 and IT WORKED!

No more service lost, 3G all the time and much better signal. So here is how to do it:

1- Go to Dialer app on Application settings.

2- Delete Data then Force Close.

3- You will lose service for a few seconds.

4- It will come back with full force.

I know, it's a strange fix, but it works on ALL Android devices (Gingerbread only I think, I haven't tested on earlier builds).

If you guys are having problems with signal, 3G or anything related, try it. This fix also worked on my friend's Milestone 1.
[Optimus One, P500, V General] Hgamgoum:
no service problem on SGS2

and how you fix the no service problem on SGS2
[Optimus One, P500, V General] kemikelx:
It works. Just clear the cache, force close and then signal is back.

Hopefully this stays permanent.
[Optimus One, P500, V General] deniso177:
I was wondering why I see you on the S2 forums, as I am getting one very soon =)
[Optimus One, P500, V General] widita:
Hi mate,

I also got random no signal problem from on my Galaxy S 2, and I found your tutorial...

However I couldn't find the "Dialler" app on application settings, do you mean the Dialer Storage? on my phone that Dialer storage has about 4.5 MB data

Thanks in advance
[Optimus One, P500, V General] piciuletz:
yup. unfortunately, ive got the same issue... i get random no signal, i am losing a lot of phone calls with this stupid issue. and it all starts from the moment i intall 4.0.4 i cat find the Dialler. i have dialer storage... thats all. i sent it to the service and they told me it has no hardware problem. they tested it and it seems to be ok... but if u ask me, a simple end user, i'll tell you that is not!. bye dudes :-l
[Optimus One, P500, V General] bleritaezo:
It is working , thank you xP

fps kernel by dr4go​

This kernel is based on the newly released LG v20Q sources, but also includes every (still) needed fix from imperticus' NeoBlaze kernel. It should work on both Froyo and Gingerbread stock and MoDaCo based ROMs. It won't work with CyanogenMod based ROMs.

Prerequisites

:

For the SWAP Enabler you need at least 384MB of free disk space on your /data/ partition. And because the swap enabler just triggers the creation of a swapfile it would be best if the data partition wouldn't be too full when executing it (fragmentation will decrease the swap performance by a whole lot!)

Features

:

- EXT2/3/4 built in

- NTFS R/W built in

- OC/UV support, overclocking up to 1552MHz [based on cpasjuste] - I recommend SetCPU (http://xdaforums.com/showthread.php?t=505419)

- SDRAM, VDE and GPU overclock [morfic]

- Voodoo Sound [supercurio]

- VR I/O scheduler

- BFQ I/O scheduler (default)

- SLQB memory allocator

- CIFS, TUN

- SWAP support (including swap notify patch for people who want to play around with compcache)

INSTALLATION

1. Remove "boot settings" from Pimp My Cpu to reset to default values

2. Reboot into CWM (v5.0.2.7-r2 recommended)

3. Install zip file from SDCARD

4. Reboot

Kernel sources: Github

Personal note:

Although I've already been built a lot of kernels (for the HTC Desire HD and also the LG Optimus 2X) I've never released them to public. And I mainly decided to do it, because I'm really really unsatisfied by the performance of this device. Imho it could and should perform a lot better. Join me if you would like to be part of this adventure. ;)

And to conclude with imperticus words: Please also don't forget the 'Thanks button'. :D

FAQ

1. Does

fps

stand for

frames per second

?

No, it doesn't. And I will never ever release this information to anyone here. Sorry folks. ;)

2. What is the difference between the normal and the safe version?

Only the installer. If you're stuck when booting, please try the _safe version. Otherwise it is the same kernel.

3. ...more to follow... :)
[LG Optimus 2x] rexren:
It's a great news to have a new kernel to try!

Edit:

ROM:Gueste2x_v2.1(base on v20e&v20m)

1.After 3 times test, quadrant score is about 2800 at 1Ghz.(HP SR1 is about 3300)

2.Andrev OC can work. I really like Myrt's apps to set UV&OC.
[LG Optimus 2x] ryaneu:
installed kernel on stock gingerbread rom.

got a quadrant score of 5700+ at OC 1.2 ghz (VR I/O scheduler)

changed I/O scheduler to BFQ and my score jumped to 6000+
[LG Optimus 2x] feav:
dr4go,

Will you add swap support to your kernel? Because this is really great feature for our low memory device )
[LG Optimus 2x] montresor60:
Fast. Smooth. Thanks!
[LG Optimus 2x] sibbor:
How come these kernels doesn't work with both CM7 and stock (like MCR) based ROMs? Isn't it possible to fix it? Modles? Kernel version? Too much patches provided by LG?

Remember HTC Hero development back in the days; almost all kernels worked independent on ROM. It was an exception (more or less) if the kernel didn't work with a specific ROM.

Looks like a great kernel, but won't flash a stock based ROM over CM.
[LG Optimus 2x] sangriaman:
What about battery life?
[LG Optimus 2x] rexren:
Could you please tell me how to change I/O scheduler?
[LG Optimus 2x] dr4go:
Thanks, that is exactly the information I need to improve the kernel. During HTC Desire HD days, there was no better scheduler than the VR I/O scheduler.

Could you also share your results you get with the Anticipatory-, NoOp- and Deadline-I/O scheduler? That way I could select the best one of those.

Thank you in advance.

dr4go
[LG Optimus 2x] dr4go:
Noted. Imo you are right, that it would be a great feature for the LG Optimus P990. ;)

Still a lot on my todo list... I already wanted to release it a few days back (as you may have noted I made the last commit on December 12th - since then I'm using it on my device.

Lastly... regarding the todo list: it's done when it's done - and as always: No information released to public before a new kernel it's out. ;)

Stay tuned folks.
[LG Optimus 2x] dr4go:
Don't get me wrong: I never had CM installed on any of my previous Android devices. My kernel may work on CM, but honestly... I have no clue.

Yes I've also wanted to try CM once, but as you know... you don't have time for everything. :)

If you are willing to test it, just flash my kernel (but leave also any other working CM kernel on your SDCARD just in case it doesn't boot anymore) and if you do so... please report back... also what works or what doesn't work...

Thanks in advance,

dr4go
[LG Optimus 2x] KillerbeeNL:
I dealt want to try this kernel buy I do not want to f**k up my phone because it is very good with v20o and rock stable.

is it possible to post a stock kernel so I can return without a flash?

thanks
[LG Optimus 2x] dr4go:
You can find your current kernel inside your zip file of your current ROM. And I doubt that it's the stock kernel you've currently have...
[LG Optimus 2x] KillerbeeNL:
its the rebuild stock v20o from hell_97 with same changelog v20o (?)

EDIT its hypnos v2.0 sp1 v20o version
[LG Optimus 2x] dr4go:
This is your current kernel you have.

To restore it, there are two possibilities:

1) Copy it to your sdcard and flash it inside a root terminal using the commands:

dd if=/dev/zero of=/dev/block/mmcblk0p5
dd if=/sdcard/boot.img of=/dev/block/mmcblk0p5

2) Copy the boot.img file inside your nvflash folder, and execute:

nvflash --bl fastboot.bin --download 10 boot.img
[LG Optimus 2x] KillerbeeNL:
tnx ..i made a nandbackup with CWM from my current rom and now a have flashed your kernel so if anything goes wrong I can go back :D

I will test this kernel for a couple of days for stability and battery use.

what's with the "windowsmgr.max_events_per_sec 120 " ??

LG 2X lcd screen has a refreshrate of 72hz so anything higher than 72 fps (120) could cause tearing in animations (?)

thanks for your effort and time
[LG Optimus 2x] spica1234:
Max_events_per_sec sets OS(software opengl related params) related frames. While actual hw fps is setted in tegra frame buffer kernel driver. Increasing refresh rate at HW level(at kernel level) gives fake higher 2d (as benchmarking software read hw refresh rate to judge 2D),Infact worsen performance and in a long run it damages LCD Controllers and can be dangerous:) Actual supported refresh rate is 60hz for mobile QVGA and HVGA and you may find 60-62 with other company except LG.
[LG Optimus 2x] el_charlie:
So, which value is recommended??? Leave it at 60??? Or 72 in our case????

Cheers!
[LG Optimus 2x] spica1234:
windows.mgr_max_events_per_sec <---that value is not at all harmfull you can keep any if you want 150-200:)
[LG Optimus 2x] shpapy:
the B.T is not stable i re-checked today since some1 complained.

it disconnectes after 3-5 minutes.

the phone reboots fine to recovery here as well, but really games dont work good.

thats a major issue.
[LG Optimus 2x] ryaneu:
I've temporarily reverted to v0.2a as i do play 3d intensive games like gt racing hd and real racing.

I do not really need the ram hack.
[LG Optimus 2x] Lo_RaT_PeNaT:
indeed, it was that file in your kernel, once removed, I can finally test your work, thank you very much for that.
[LG Optimus 2x] KillerbeeNL:
I was writing some text here and multitasking to settings to see the version of the rom the screen freezes and had to pull battery

using the latest fps kernel an v20o hypnos 2x v2. and BB 725 from v20L (original)

if there's a problem like me I think it would be a good idea for the developer to mention the rom that your using, different roms means different results.

it's like cooking for different mouths and no one has the same taste......
[LG Optimus 2x] el_charlie:
I reverted back to 0.2a. It's the best for me. Deleted the file and I use SetCPU to set the max speed to 1,1GHz.

But now I have one question: Does this version uses both cores at all?? I find this kernel very fast and smooth. Antutu gives me a high score.

Cheers!
[LG Optimus 2x] KillerbeeNL:
you can use system panel from market and open the app ..click CPU and try to activate second core by using quick scrolling in app with finger movement.

that should "trigger' the second core.

cheers
[LG Optimus 2x] el_charlie:
Thanks!

Second core is inactive until I start the scrolling. That's fine I guess.

I still like 0.2a more.

Cheers!
[LG Optimus 2x] Wing_Zero85:
Finally a kernel with the ram-hack for the stock rom!! Great!

I'm gonna testing it :)

---------- Post added at 11:38 AM ---------- Previous post was at 10:41 AM ----------

RAMHACK DOES NOT WORK! -.-

380mb avaiable -.-"
[LG Optimus 2x] RohanAJoshi:
does this kernel support 2nd core sync like spica's RC-11 ?
[LG Optimus 2x] shpapy:
Yep supported
[LG Optimus 2x] carburano:
so guys...

Could you suggest me optimal settings to put on my new rom?:p
[LG Optimus 2x] spica1234:
Sorry for offtopic regarding your question,

First of all,

Remove many unneeded files from init.d folder. And if you integrate any of my PPs than these files are not at all needed:) they makes rom's functionality more completed rather than improving performance and cause many unpredictable issues hard to be traced;)
[LG Optimus 2x] Wing_Zero85:
the ram-hack on fps 0.3a doesn't work.
[LG Optimus 2x] carburano:
Hi Spica... My question was about OC and UV with this kernel...:o

Regarding PP, this time I won't use it...

Thanks for your suggestion!!
[LG Optimus 2x] rexren:
Blue tooth problem on v0.3a

+1 ,B.T. is also not stable in 0.3a. As I reported before,it was disconnected with headset in 5 mins but phone still show connected.:confused:

My rom is gueste 2x 2.1 and bb is v20m.

0.2a is the best choice for now.
[LG Optimus 2x] dr4go:
Well... v0.2a uses both cores with ~900MHz and up. v0.3a needs ~1040MHz for both cores to be active.
[LG Optimus 2x] dr4go:
It does work, but with 32MB on v0.3a instead of 64MB.
[LG Optimus 2x] dr4go:
No both cores are not directly sycned and I won't add that feature since I don't see any use in this - except a higher battery drain.

...i.e.: Both cores scale up and down independently.
[LG Optimus 2x] dr4go:
I don't see why BT would have problems in v0.3a - yet, but I will certainly take a look into it. :)
[LG Optimus 2x] dr4go:
Glad you can use my kernel without that file. It seems you must have a very "complicated" device when it comes down to UV. It would be interesting to know which frequencies cause you some troubles.

But strangely... I don't understand it at all, because v0.1 used exactly the same voltage table as v0.2 and/or (both the old and new) v0.2a. :(
[LG Optimus 2x] Wing_Zero85:
No that's not true. If you use "free" command in terminal emulator, you can clearly seet that are avaiable 380Mb of RAM.

IT-DOES-NOT-WORK.

Post a screenshot to prove that i'm wrong.

[LG Optimus 2x] shpapy:
@Dr4go any updates on the kernel?

issues are B.T and 50 hrz memory leak

Maybe incorporate lowmemorykiller.c from Spica?

And installation of apps is really slow
[LG Optimus 2x] Divyan:
Tested your kernel with Paul's GR6 version. For me everything works great..! Thank you so much for the kernel..!:D
[LG Optimus 2x] shpapy:
What about u.v on 1.2/4?

Thanks
[LG Optimus 2x] Divyan:
I have set UV for 1216 Mhz as1100 mV and for 1408 Mhz, 1225 mV. Works without a problem.
[LG Optimus 2x] shpapy:
o.k... so now i really wonder... i'm running the rom by hell and cannot uv @ 1.2/1.4

phone restarts.. i thought it supposed to be related to kernel only.
[LG Optimus 2x] SuperSkill:
It is the kernel, but your phone might not handle it while others don't. It's the same when example oc a computer ;)
[LG Optimus 2x] shpapy:
with spica and others its fine on my phone,
[LG Optimus 2x] dr4go:
Unfortunately not. Due to travelling, birthdays, once (when I would have had time) forgotten the notebook @ work and helping friends when moving to other flats I'm currently really lacking time. :(

Today also my internet refused to work - what a mess... I will keep you posted in the coming days.

By the way: lowmemorykiller.c is already there.
[LG Optimus 2x] dr4go:
Of course not... some cpus / chipsets are better than others. And also keep in mind, that there are different versions of our phone out there, too!

EDIT: And also keep in mind, that I ported some ARM CPU features of 2.6.35+ sources to our phone. That could also be the reason why the CPU doesn't like that much UV, but it of course is faster because of that.
[LG Optimus 2x] shpapy:
thanks for the update, hope you will find the time for stable this release more :-)

lowmem is there but not functioning properly since after 50 hrz phone lags big time.

i can send logs over the weekend if you are interested.
[LG Optimus 2x] erups:
Hi!

Running Topogigi's V2 SP3 with Neoblaze kernel (should be V20e).

Anything strange I should do before flashing this kernel?

I had problems with spica's kernel, it wasn't perfectly compatible with my rom.

And I'm still pretty happy with my rom, mostly the look and polish so don't ask me to change :p
[LG Optimus 2x] shpapy:
Nothing special just make sure to remove all oc / UV settings before flashing, this zip also cleans the cache for you

Let us know how it goes.

Its compatible with ext3 and 4 so no worries.
[LG Optimus 2x] Sckank:
Dr4ago: so if I limit the cpu to 1 ghz the 2nd core wont work?
[LG Optimus 2x] Lo_RaT_PeNaT:
dr4go any updates?:D
[LG Optimus 2x] dr4go:
The 2nd core won't work if you choose a frequency below 1040 MHz.
[LG Optimus 2x] dr4go:
Didn't you see the v0.4? :D

Just kidding. Sorry folks, I didn't have time to bring any update to you. Most probably I'll have again a bit more time for our phone.

The changelog:

- Based on LG's v20Q codebase

- Total removal of RAM hack (may be preliminary, hadn't the chance to look into a few issues, yet...)

- 1st try to fix 50hrs+ issue and a bluetooth incompatibility
[LG Optimus 2x] SuperSkill:
Nice comeback :) you're needed as most devs work on CM, thanks :)
[LG Optimus 2x] Lo_RaT_PeNaT:
dr4go, I congratulate you, surely did not expect what I found with his latest work, and I must say I was pleasantly surprised, I am delighted the few hours it took to operate the performance that brings to my phone, I sincerely thank you very much.
[LG Optimus 2x] shpapy:
here we go again!!!!! woooohooo!!!!

so lets test B.T and 50hrz issue.....

will be back soon (after lunch and B.T testing)

Sorry for all the editing, this is the feedback.

1. since memory hack was removed , reboot to recovery works fine with o2x recovery from the market.

2. after dirty boot (30 apps , mails, etc...) 160Mb used ram & 150 free (swap enabled)

3.

2nd core always offline i use 1200 so it should be online but it isnt.

4. after soft boot with older kernel the phone would start but there was no radio (i.e. calls) this seems to be solved now.

5. wifi = since v20q intruducted new wifi module its time to test.. ahha wait this post actually tests it :-) also reconnect / disconnect etc....

6. scrolling is so far really good (i scroll a lot in google+)

7. games cannot test since i work now ... maybe in the toilet break :-) update: N.f.S works very good for now we need to test after 20 hours at least of usage.

8. app installation still lags BIG TIMMMMMEEEEEE

more to follow.
[LG Optimus 2x] CaptainHook8:
Thanks man!

I will try it!
[LG Optimus 2x] dr4go:
Thanks for your feedback.

Regarding 3) I cannot reproduce this here on my phone. The 2nd core works fine either with 1040MHz and 1216MHz if it is really needed (i.e. SystemPanel with a lot of scrolling up/down).

Regarding 8) I will look into that, but since installing is not as important as actually using the phone, it is not that high of priority (as for example BT and / or 50hrs lag).

As for BT: I'm pretty sure it does work now, although I don't have access to any BT device right now. So let's see how it turns out. :)
