Mount SD Card as USB Storage

Hello, I am desperately trying to mount the sd card of the phone as usb storage on windows. It worked before but since I flashed WIUI it won't show up. Now I have gone back to cm7 and it is still not working.

Here is what I did:

I thought it had to do with the phone having an internal and external SD, so I searched the forums and found this: Stock Mounting SDcard for Cyanogenmod and MIUI (universal!). I didn't understand what is meant by: "Before flashing make sure the patch folder /mnt/sdcard is present _ExternalSD

If there is not create it"

As there wasn't one I created a folder named "_ExternalSD" in the directory "/mnt/sdcard", then I flashed the zip which was located in a previously created folder named "/mnt/sdcard/ROMS" where I put all the Roms.

The result was that the sdcard was not recognized by es file explorer anymore, so either I made a mistake or the zip wasn't intended for my case.

Meanwhile I am back on CM7 after a full wipe. The SD Card can now be accessed by a file explorer again, but it still cannot be mounted as usb storage (neither from cwm). Is this a general problem or do I need a special fix? Any help is appreciated. :good:

Edit

: Okay, I can mount the SD Card as USB storage on all ICS roms but not on GB... ICS on the other hand comes with other critical issues such as no HWA. Is there any ROM that has all features necessary for daily use working?

Edit 2:

To everyone having the same problem like me and just searching for a clean ROM that you can use as daily driver -> Try Django Manouche. Easy to install thanks to Aroma installer which is started right after you choose the zip in cwm and everything works as intended.

Hey,

after I fixed my USB connection problem I now have trouble installing custom ROMs.

I have Paul's 4.0.0.5 - ClockworkMod Recovery flashed and both ROMs I've tried to install (CM9) freeze on the boot logo.

I got a stock Rom backup and can restore it converting back to EXT3.

Super One Click root works.

I know this might be a nooby question but I really don't know where to go from here.

Is CWM 5 required to flash CM9 ROMs?

Help would be really appreciated. I've rooted many phones before, but this one is really driving me mad.

EDIT: CWM-based Recovery 5.0.2.8, same problem ROMs freeze on boot.

[LG Optimus 2x] kohos:
Hey, thanks for the reply, it's working now.

I did complete wipes before installing each time but it just hung.

I'm sure it was an issue with the recoveries. CWM 4 did not work on any CM9 ROM in the end.

5.0.2.8 worked but not when I wanted to Install Domination first. I gave it 4 tries to boot but it always froze.

Then installed Nova and it worked, after flashing Nova, flashing Domination suddenly worked too.

I know this makes no sense, maybe I did something different along the line. Now I'm testing various ROMs and Kernels wee o/

I've got a question about a battery stats bug.

It might be a CM9 related thing since I never used a stock ROM on this phone, so I'm asking it here.

I got 2 batteries basically, which I swap almost daily.

It works for the first 1-2 days and then after a battery runs out and I swap the next fully charged in, the meter shows the stats from the previous battery 1%-4%.

Wiping battery stats in recovery fixes it only until the next swap. Was just wondering if there is a more elegant way to solve this.

EDIT: I got this on all CM9 ROMs I've tried. Paranoid, Domination, Nova.

tun module Lg Optimus 2X

Hi everyone Im new to this forum and it is also my first time to use custom rom so can someone help me on where i can get a tun module for my Lg Optimus 2x P990 CM7 UNOFFICIAL (JUL25) temasek's UNOFFICIAL BUILD 130 with kernel: 2.6.32.55-cyanogenmodroot@temasek#1 Im planning to use droidvpn. When I tried to use tun.ko installer from the Playstore it says: Cannot find compatible tun module for your device.

Thanks in advance
[LG Optimus 2x] aragorn7:
I've noticed the same, but also noticed that sometimes it shows the full 100% when I place he second one. I have a possible workaround but haven't confirmed with a controlled experiment, but try this next time you swap batteries: leave out the battery for at least 15 seconds before adding the new one. I am suspecting that this might help reset the battery stat.

Please report back when you swap next. I'll also try myself.
[LG Optimus 2x] kohos:
Haha awesome sarcasm aragorn : D
[LG Optimus 2x] aragorn7:
@kohos

I did the experiment today and it worked fine. Battery #1 dropped to 7%, powered off, waited 15 sec, popped in the fully charged Battery #2 and it correctly showed the 100% after boot.

I am currently recharging battery #1. When my battery#2 that my phone is using runs out of juice, I will do another experiment where I don't wait the 15sec to see if I can repeat getting the wrong battery percent value.

Best custom ROm

Hello

I just buy this phone.

I see that is a few problems ith the original ROM

Please tell me what custom rom is most recomended to flash in my phone.

I'm interested for maximum stability and to functin all things in the phone.

Thanks
[LG Optimus 2x] aragorn7:
I just finished the second experiment and yeah, my suspicion was correct.

When I change batteries, if I wait for a while (15 sec) before putting on the spare, then the battery level is correctly displayed.

But if I put on the spare quickly without any wait in between, then the reported battery level is at whatever value it had before the last power off.

CM7 Rom - Cannot End a call

HI All,

I've search this topic and did not find someone who has a same problem with mine.

I've flashed many rom. Stock based, CM7 (from Temasek Build) and MIUI.

This problem is when i used CM7 rom. It happened when I called someone or received any calls.

If the other person end the called earlier than me, then my phone cannot end a call immediately.

Even if i pressed "end call", the called cannot be ended, it just written "hanging up".

The sound "tut tut tut" always present until 30 seconds, before it end by itself.

This problem was not happened if I end a call earlier than the other person.

I've tried to flash many different combination of BB+RIL, such as:

725+ 725 (10d europe ril)

725+ 725 (20d Asia ril)

725+ 218 (10b ril)

521+ 218 (10b ril)

Just ask here if anybody have a same problem with me.

Hey guys,

the original headphones are worst. (The net of the membranes has come loose, thus there is zero damping and it is louder one one side and got horrible sound).

Therefore i searched for a new headphone. I decided to buy the Logitech UE200. Unfortunately there are several editions on the market.

amazon.de/dp/B005LGUZQW --> Ultimate Ears 200

amazon.de/gp/product/B004B8U7GO/ref=noref?ie=UTF8&psc=1&s=ce-de --> Ultimate Ears 200vi

amazon.de/dp/B005FYIL20 --> Ultimate Ears 200vi with Microphone for Ipad/Ipad2

(sry for not embedding the links, i am not allowed to do it! Dont have the 10 post requirement!)

the plug of the Ipad edition looks pretty much like the original one. Do I have to pay attention to which plug it is? is also a 3 pin plug working or has it to be a 4 pin one? Are there differences at the 4 pin (due to occupation of different setting on the pins?)

Would be nice if someone could help me! :good:

ISSUES

- No media acceleration: No video decoding, no video encoding.

- Apps made for Android 4 with their own specific graphics implementations (Chrome is a good example) will be glitchy.

(tnx to NVIDIA and LG for no drivers)

I tried until now Nova HD(hei1125), Domination(owain94) and ParanoidAndroid in this order and they are all really great work.

In my feeling they are all every day use ready but have style differeces thats why i started to change roms.

U want tipps?

One tipp is keep searching for the rom that fits to you.

Second is if u are beginner start with roms that provide AROMA installer like the Nova HD, because it is much easier if u dont need to think about right GAPPS, RIL and so one that things will come with time (very fast :D).

Hi,

As in Canada and north america in general, I can tell that the latest version is the one released by LG itself, 2.3 Gingerbread. However, you have so many other great ROMs that you can install (or flash) on your P990.

For rooting and installing the stable Cyanogenomd (cm7) rom, go to this:

http ://wiki.cyanogenmod.com/wiki/LG_Optimus_2X:_Full_Update_Guide

(i'm new to posts, but experienced in Android stuff, so no URL links for meh :()

After rooting, you can follow the same steps or similar steps, (otherwise specified steps by OP) to flash ROMs posted by OP, and

they generally are posted in Optimus 2X Android Development section of the forum.

Hope this helped. :)

---------- Post added at 07:38 AM ---------- Previous post was at 07:34 AM ----------

Just noticed this :)

For me, I love Paranoid Android. They have a ICS build which is official.

or

a JB build, which is still nightlies (correct me if I'm wrong).

I've tested both and they all work greatly without major bugs. Smooth enough for a device like P990.

You can try all kinds of ROMs yourself. For the best ones, I've simply Googled. :)
