[LG Optimus 2x] Piter1225:
I would bet this was around 20%, not 40%, but I guess the early reviews will cover the battery life for sure.

Android always presents a bit less battery, than it really is.

It would be better, if manufacturers would use percentage batt indicator instead of default one.

EDIT:

Also, look at the clock: until 5:44 min of the video, when the battery is about 70%, it is 19:30 on the clock.

After 5:44 min of the video the clock changes to 20:17, batt indicates around 60%, and stays at this level until end of video, even if he uses most of functions (like HD video, web browsing) after 5:44.

Also, notice that WiFi is all the time on.

I would say, that's nothing uncommon in this battery life, but again - we will see it in early reviews.

As you can say our Korean friends could help us!

BUT STILL NO SECTION ON XDA..

I wonder what is the reason that prevents the opening of a section in the forum.

Will Xda not support Optimus 2x?
[LG Optimus 2x] Piter1225:
Yes, thats strange. The Motorola Xoom/Xperia Arc is not even out (while 2X is) and has own section, the device is very popular (almost every known tech blog writes about it).

Hope that mods will add the section in following days.
[LG Optimus 2x] STHNS:
I mean you want dual core but you don't want to burn juice? What did you think they would have? Keep in mind stock is 1500mAh as cpu using more current due to having dual die.

Really? Never heard this one maybe you should look into your batt stats and see what you have in first place. Hopefully you didn't fall victim to those notorious chinese fakes.
[LG Optimus 2x] yyhoney:
2x will be realeased tomorrow in Korea.
[LG Optimus 2x] yyhoney:
not yet...

2x will be realeased tomorrow. then i'll check that i can rooting the device.

if it'll be possible, u can get a system dump.

And i anxiously wait for your FroyoSenseDefy Edition. Many korean wants that, too.
[LG Optimus 2x] Piter1225:
I heared that nVIDIA prepared the Tegra2 in way which will reduce to power usage, take a look:
[LG Optimus 2x] Dexter_nlb:
if you can make a quick dump of 2x, its very much appreciated. i am even willing to share a special edition of sensedefy for that big favour if you figure it out and you can dump it :-) looking forward to hearing good news on that topic.
[LG Optimus 2x] DJ Palmis:
The Xperia Arc is far to be released.. Well and Motorola does not allow to customize ROMs!

But they have a forum.. That's funny!

Maybe there are no moderators..

Well.. We can talk here! :)
[LG Optimus 2x] Dexter_nlb:
thats not true.. i got some pretty customized roms on my moto's.. and thats not just graphcis/app mod, thats hardcore modding and so on. but yes they do not allow us to change kernel for now.. and filesystems we got around that one..

check my sig if you doubt moto has custom roms on their locked mobiles. and please do not say its not a mod, Mod=modified which can be everything, so custom it is indeed.
[LG Optimus 2x] DJ Palmis:
I don't dare say anything.. I was just referring to this news: http://www.androidcentral.com/moto-employee-confirms-locked-bootloaders-and-bad-attitude

I don't know NOTHING about android world and I know only HTC policies!

That's why I am hesitant to buy Optimus 2x: I don't know LG policies about custom ROMs.
[LG Optimus 2x] DJ Palmis:
Wow we have the forum!!
[LG Optimus 2x] hdurina:
and my journey will continue with XDA from the TP2 forum to the LG Optimus 2x forum...if only they release the fone with as much dedication of the forum mods here! Awesome job in creating separate forums for the soon-to-be-unleashed monsters.

Helping with Development?

Hi everyone-

I am an expat currently living in South Korea and I have just bought the Optimus 2x. I would like to contribute to development for this phone, but I have no idea how (this is my first android phone ever). I read earlier in this thread that someone requested a system dump. I am glad to help in anyway I can, but I need detailed instructions on how I can get you guys the pertinent information. Let me know how I can assist!
[LG Optimus 2x] Dexter_nlb:
Nice :-) and thanks for your reply here.

please try the OneClickroot from this thread, ver. 1.6.2 you should use..

of course use need the SDK installed to have ADB enabled..

your drivers that comes with the mobile, might already enable ADB, but i suspect it not to.

an introduction to ADB here ignore the platform, parts of it (tools) is still standard and needed.

this one is a reference to another Tegra2 based product, where ADB is installed with small changes to configs (hope you get it working)

see here

when you finally got ADB installed, and you see windows registering the driver, you need to enable usb debugging in development

ie. goto MENU -> settings -> applications -> development . and enable usb debugging, you pc should now install a new driver when you attach the mobile to your pc.

then in a CMD shell window, try this "adb shell", and see if you get a connect with a prompt. you might need to switch to location where adb got installed/copied to.

if it works. try run the oneclickroot on your windows, its very easy to use and automated process.

lastly if it works.

re-run the "adb shell" and run these commands

Suggestion 1

cd /system
busybox tar cf /sdcard/2xdump.tar . /init.*

if no busybox is available , then do it the simple way

Suggestion 2

cd /system
mkdir /sdcard/mydump
cp -a * /sdcard/mydump/
cp /init.* /sdcard/mydump/

a folder on your sdcard now contains all files, where you can zip them on your pc.

if suggestion 1 or 2 works, copy the file(s) from your sdcard to your pc and upload to multiupload.com or similar . and post the link ie. maybe as PM to me or someone who can upload to a EU location too, before maybe link goes down because of too many getting it from asian location.
[LG Optimus 2x] cvitur1:
Thanks for the instructions!

I gave the Universal Androot a try and it was unable to root my phone. I will try the other methods suggested in the thread, but it will have to wait as I am currently at work. Will keep you updated and try to get this thing rooted as soon as possible.
[LG Optimus 2x] bypass23:
You don't need to ROOT your phone in order to dump the system...

LG do have USB drivers with ADB included : LG Mobile Support Tool

LG P990 is not listed, LG P500 should be tried...

Obviously will not have busybox installed and doesn't need to have access to the sdcard :

adb pull /system C:\P990system

This seems to be the easiest way of getting the system files for now since cvitur1 as he said is new to android.

Not a complete dump but a start... I'm willing to help him step by step in order to get the real system.img and boot.img which is important to me :D
[LG Optimus 2x] cvitur1:
I believe I have gotten root access and installed busybox and followed your instructions. I copied 2xdump.tar to my computer, however, the file is 387 mb in size...is it supposed to be this large?
[LG Optimus 2x] bypass23:
yes make sense you can always verify with this :

adb shell
df -h

It will output the file partitions and you can compare actually if you could post the output it would be great too :D
[LG Optimus 2x] Dexter_nlb:
you can pack with zip, but just inform that you did, or leave filename intact. because a .tar is not not used with zip , but with gzip(linux)
[LG Optimus 2x] Dexter_nlb:
of course you do, as some files will not be copied (its not shown with busybox, just skipped) , so you end up with missing files..

but i agree, most files will be dumped, but its will not be perfect..
[LG Optimus 2x] bypass23:
Symlinks are not being copied with root or not...

you need to extract the system.img in order to have them.
[LG Optimus 2x] Dexter_nlb:
huh?

what does symbolic linked files has to do with tar or root? of course the "link" is by default tar'd and not the referenced file, otherwise we would be in some bad s... if that were the case, and always need to do a dd or similar :-)

as long as /system is the starting point, most files will be included, also those symlink'd too... (you get the file AND the symlink which is a proper way of extracting a mirror of the system)
[LG Optimus 2x] cvitur1:
all waaaay above my head....I have what i hope to be the system dump file, it is 387 mb, what is a convenient way to get that to you?

also, i am in the process of doing the "adb pull /system c:\p990system" command and when that is finished, i will zip it up and post it in the same manner...just let me know the best way to get the files to you :)
[LG Optimus 2x] Dexter_nlb:
anyway you find it possible to upload the file to.. as long as you know we can access it.. and no rapidshare link, those are limited to 10 download i think, which is annoying..
[LG Optimus 2x] bypass23:
just saying that adb pull wont get the symlinks rooted or not

and busybox can be installed in /data/local without root
[LG Optimus 2x] bypass23:
Both method will result the same so you don't need to create another, the .tar one you did is just fine.

The next step is to extract the .imgs instead of copying files...

If you can post the output of df -h I can prolly make a step by step guide for you.

I am looking to buy this card soon, and was wondering if Desire does actually support class 10 cards. I know, it's serioux, but hell, 8gb and class 10 for 12 euro sounds too friggin good. Will it be fine with my phone?
[Desire Accessories] RaivoNaama:
It supports it, yes. But in my opinion class 10 is a bit overkill for the day-to-day things you do with your phone. A friend of mine had a class 10 8gb card and bought a class 6 16gb card. He said he noticed no difference..

But yeah, with that price! :D
[Desire Accessories] lvnatic:
I mostly need it for app2sd ROMs as well as for the DHD ports, so big speed is what I need. Aside from that, more space for movies and music is always good. I am currently using the stock one that came with the phone, class 2, 4gb and sometimes I really need more space.
[Desire Accessories] m4dm4n123:
Umm, SDHC vs. microSDHC ? Link is for SDHC, you can't fit that one in Desire . :)
[Desire Accessories] kl_arnet:
You will spot BIG difference in running any DHD (or normal) + DATA2SD Rom on class 6 and 10. If you are using the phone "on daily basis" you don't even need root. If you want to have full custom lil monster of space (DATA2SD), performance (Custom ROM) and speed (Class 10 SD Card + Overclocking), class 10 16 GB card is must have ;)
[Desire Accessories] Feltwo:
Yes it supports Class 10 . I completely agree with the previous post ;)
[Desire Accessories] Kalavere:
Yup yup, like m4dm4n said, it's physically about four times to big to fit in the Desire. Wrong card type. :)
[Desire Accessories] stingerpl:
Can you prove that with any benchmarks or is it just your imagination?

Class 10 means it's capable of writing 10MB/s. Apps2SD is mostly about reading data and I'm pretty sure you wont get much difference in speed between class 4 and class 10 in reading on a phone.

Also I'm afraid that the phone/app itself might not be able to write that fast.

I would spend the money on class 2/4 32GB card and have all my music with me.
[Desire Accessories] GuySmiles:
I just recently bought the Patriot 32gb microSDHC class 10 card and after careful troubleshooting I found that it was the cause of my screen not waking up and random crashes. Perhaps older class 10 cards would work, or maybe it's the mix of 32gb with class 10? I'm getting the sandisk 32gb class 2. Hopefully that will work better.
[Desire Accessories] stingerpl:
I didn't know they make 32gb class 10. If the card makes your phone buggy that is surely not because its class 10. Maybe you should get the card replaced?
[Desire Accessories] Ben86:
I can confirm 16GB Class 10 MicroSDHC works fine on Desire:

http://cgi.ebay.de/Team-Class-10-Mi...MemoryCards&hash=item45f7e46ce0#ht_2460wt_905

I use A2SD+ and its way faster than the shipped class 2
[Desire Accessories] harvin23:
I bought a kingmax 16 gb class 10 and im very happy with the performance. I use DHD rom with data2ext and its very fast. Plus the mounting time or should I say preparing sd card time during the startup is much much faster compare to me previous class 2 memory card. If u have the money go for class 10. Otherwise class 6 will do fine.
[Desire Accessories] kl_arnet:
I didn't follow the thread. I've bought class 10 16 gb a-data card and collecting it today. I'll post the benchmarks of class 2, class 10 and maybe class 4 cards running on StarBurst DATA2 ROM.

[Desire Accessories] kl_arnet:
All tests on phone are with running DATA2SD script, so please note they would be higher on clean stock rom (as DATA2SD script is constantly using card). That is why I insist class 10 is must have if you want to get good performance over DATA2SD ROM.

[Desire Accessories] OpusX11:
kl_arnet: of the cards you tested, which would you recommend for speed/performance vs cost as the best "bang for your buck" ?? I am returning a Patriot LX Series 8GB Class 10 (PSF8GMCSDHC10) as I could only achieve an average of 2.5 for write speeds using StarBurst 1.2.1. The read speeds were fantastic at greater than 12. But the write speeds made the phone a bit too laggy, so I have reverted back to my stock 8gb samsung class 2 and Modaco R9 until I can find a decent class 6 or class 10 card that will have guaranteed decent write speeds in StarBurst.

thanks!
[Desire Accessories] kl_arnet:
This ADATA class 10 16 gb just amazed me.

Model:

They are sold in 2 versions but card itself is the same. Difference is only in add-ons.

AUSDH16GCL10-RM3RDRD Cheaper with red USB adapter (the one I've got)

AUSDH16GCL10-RM3BKBL More expensive (about 8 $ more) with SD card adapter (that you don't need or have plenty of those), with black/blue light USB adapter (wich U will use probably once for benchmarks)

Both USB Adapters are really small and you can show off with MicroSD card literally going under the USB plug.

Price:

I've paid 125 PLN that is about 40 $ at internet shop (be careful on ebay as they sell chinese cheap fake crap from dealextreme.com). Card is doing very well especially if you compare speed and price to Kingston or SanDisk.

Speed:

I'm not professional IT technician so I was really surprised that home made benchmark went better than Kingston's (usually overboosted) found on benchmarking site.

Performance:

StarBurst with Siebre's dedicated DATA2SD runs smoothly, especially after last Siebre's dalvik2nand update.

Long Story Short:

I'm happy with cheap genuine ADATA Class 10 16 gb card.

Swyped via StarBurst Desire.
[Desire Accessories] OpusX11:
Thanks, A-Data and Wintec seem to be recommended for cheaper cards, though the prices in Canada are not nearly as good as where you are it seems. I may have to try and get the 8GB A-Data class 6 when it is back in stock at a Canadian online retailer.

thanks again for the metrics and recommendation.
[Desire Accessories] Mike Philippens:
Please consider a few things:

There are 2 very important factors that seem to be overlooked. First is the maximum speed if the SD card controller in the Desire. A card can be as quick as it wants, but it won't transfer data any quicker than the controller is capable of.

Second is the speed of the card itself. Sounds obvious, but it isn't that easy. The class in itself says absolutely nothing about the actual speed of it. The class tells us a minimum. So a 'fast' class 4 card can perform as good as a 'slow' class 6 card.

And about the 'benchmarks': a benchmark is just another statistic. Speed is influenced by many factors. A full card is slower, and a card in a busy system too. Testing a card through a USB cable on a PC is useless because the USB connection is a factor too. Filesize is also a factor. A card can be quick with one big file and very slow with many small files or the other way around.

Ergo: look for a quick card, which is not always the card with the highest class. Not all class 10 cards are quick!

BTW:

The Antutu benchmark tests my Transcend Class6 8Gb card as 8,3MB/s Write and 13,4MB/s Read speed. A previous test was a bit quicker with 9MB/s write and 14MB/s read. My Desire is not overclocked. I don't know how this program tests, but another test program gave a much slower speed. But that one used 1 big file. I guess Antutu uses small files. So be carefull with reading too much into the benchmarks.

[edit]

The 'SD Tools' app is in a league of it's own. It tells me that my card has a write speed of 9.2MB/s and a read speed of (are you sitting down?) of 27.8MB/s. Just shows you how different (and realistic) benchmark results are.
[Desire Accessories] naruz:
Mustang 16 go classe 10

12 Mo write

19 Mo read
[Desire Accessories] Draqula:
I have read in many threads about problems with class 10 cards, making Desire unstable. Perhaps it was only the first class 10 cards and technology being not mature enough - I don't know.

But in my opinion:

Consider class 10 if you have received positive feedback on that specific card model and need the extra speed.

Get a class 6 card from a respected manufacturer if you want to play it safe and just want it to be fast (not the fastest).
[Desire Accessories] stonegroover:
Just want to add to what Mike Philippens has written.

As far as I know, many of the higher class cards have been produced by biasing performance to continuous read/write speeds, for use in camcorders/cameras etc so they can record ultra HD or burst capture etc. HOWEVER, for use in a phone, which needs greater random read/write access they can suffer compared to a regular class 4 which is a better balanced card. There is a lot of this going on in the HTC Mozart pages here on XDA, where I've been spending time (had a Mozart, ROM'd it and gave it to my girlfriend, she loves it).

Many people have tried different 32gb/16gb cards, different classes from 2-10 and the results have been surprising. WP7 seems to be unusually fussy about the cards that will actually work with it, and the only card guaranteed to work everytime is SANDISK which says a lot about the quality, and people have been finding that performance with a Class 4 SanDisk card is better than performance with a supposed Class 10 card by another manufacturer such as Integral, Transcend etc or even Samsung and Kingston.

In the end I bought a 32gb SanDisk Class 4 off Amazon, for a lot more than they are on eBay at around £28, apparently there are loads of near-fakes on eBay (only way I could guarantee it was genuine- the chinese are using genuine 4gb SanDisk cards and then re-branding and re-coding them as 32gb, the card thinks it's a 32gb, reports that it's a 32gb card but obviously runs out of room and has errors as soon as you try to put stuff on it).

Hope this helps anyone thinking about buying a card- generally you get what you pay for and if it sounds too good to be true it usually is.
[Desire Accessories] Backfisch:
Hey, I have bought a class 10 Samsung card with 32gb.

[Desire Accessories] Spatnonkl:
Why do you guys only post sequential transfer rates?

Shouldn't A2SD+ be more about access times?

I'm not a dev. Just asking.

good thread

Nice to have a thread like this with a lot of recommendations and benchmarks. I use the stock card that came with the Desire, but I am pretty sure it is slowing me down after I started using an sd-ext partition.

WIll buy new sd card based on this thread.
[Desire Accessories] jim2san:
I am using sd 8 gb class 10 and works fine
[Desire Accessories] akhillad:
No.. the desire supports till class 6... A class 10 card vll work at the speed class 6....

So better u buy class 6 nd don't waste money....
[Desire Accessories] Looloup:
True, but if you put the card into another device ie a PC to transfer films, music etc then you can still profit from the higher speed.

Just got a 16gb class 10 card from Amazon for £11, so not even too much money.
[Desire Accessories] agismaniax:
yes, i agree.

i have apacer 8gb class 10. with sd-tools, i only get write arround 6-7MB/s and read arround 14-16MB/s.

my desire's stock memcard can write 4-5MB/s and read 12-14MB/s.
[Desire Accessories] NiteAngyl:
Exactly. Class 10 is an unnecessary luxury.
[Desire Accessories] InMyBedNow:
Class 10 SD cards are only leading when transferring large files usually over 100MB. Small files e.g Dalvik Cache and app data would really ruin the point of a class 10. Class 4 or 6 would be great for A2SD/Data2Ext etc.

And for your original question. Yes, out Desire does support class 10.
[Desire Accessories] eevilgenius:
Yes it does support it. Using Lexar 32Gb Class 10. Works great.
[Desire Accessories] Eon83:
Generally a class 6 card will be enough. I dun find any performance difference when i switch to a class 10
