[Q] Screen stays black when unlocking. - T-Mobile LG G2x

My dad's screen stays off when he tries to unlock the phone or when receiving a call. It takes a few tries to get the screen on. CM7 screen wont turn on at all. What can I do.

What?
Sent from my HTC Vision using XDA App

All SD cards have a class. Class 2 to 10 ten being The best .the better the class The better the file transfer. Cause it sounds like you got a bad download. also did you wipe cache dalvic cache format system before updating to cm7

This was happening on stock too.

Then I would say flash back to stock and send it in for warranty

Lol I'm glad someone else finally actually posted something helpful for him. Timothy was like an IT guy "did you try turning it off and on?" No offense.

THANK YOU! I'll try that when he's not using it. However how would the SD card cause his problem?
Sent from my HTC Vision using XDA App

I fought with this issue for a long time, ended up using EaglesBlood's ROM and it didn't have the same issue. It's also not happening with EB's ICS ROM. Just in case the SD card isn't the problem...

The SD card could have a bad file on it or if its not a higher class it could lose some important files when transfering
Sent from my LG-P999 using XDA App

SD was not the issue, I'll look into EaglesBlood's ROM now

The same thing started happening with my phone recently. It stays black when trying to wake the device and stays black during a phone call. It's only happening sporadically though. Kind of like a bratty child, only working when it wants to.
I've had this phone for about three months now but I rooted this device the same day it came out the box. I'm running CM7.1.01 Stable.
My SD card is a 32GB class 10, but I don't see how this could be an issue with the ROM.
When it happens and it won't respond to power button or volume key I just yank the battery and reboot..
Could it be a hardware issue?

Two recoveries?

After downloading the newest ROM manager from the market, it now looks like I have two recoveries installed. If I boot into recovery from ROM Manager, I get the new blue one (with int SD support). But if I boot from the power menu, I get the old one. Something tells me I screwed something up, and I'm not touching anything until somebody tells me how this is even possible. WTF did I do?

No problem there. ROM manager is only updated false flash rom. Old one is the nvflashed real one.

Ah. So is it safe to flash from either one? Having access to the internal SD would be a lot more convenient.
Also, is there a thread somewhere pertaining to this situation?
Sent from my LG-P999 using xda premium
There is an even better scenario...download the utility by tgagunmann in the development section, and flash the latest cwm, which allows both internal and external from boot recovery.

[Q] SD card issues on CM7

I am having lots of trouble with CM7.....I have a G2x runing Cm7.1.0.1....Everything works perfectly expect SD card....Whenever I use the camera to take a pic I can't get it...it takes the pics and then deletes it in one minute.....I can't even transfer files on the sd card cuz it gets deleted by CM7.HELP ME OUT GUYS!!!!!
That's weird, I'm on the exact same rom and don't have this problem. Does the SD card work when using in other phones or other roms or even in your computer? If it doesn't, your SD card is corrupted.

Works on HTC hd2 and my HTC wildfire but has this aerodynamic issue on my g2x only.

Try reflashing the ROM and see if that fixes the problem. That is usually the best fix for major problems like this. Just make sure to do some sort of back up first so you don't lose any data.

i'm using liquidbeats
had upgraded the baseband and flashed liquidbeats via CWM and had problems with no service but reflashed stock rom and baseband,that resolved the no service problems but since then the phone aint been picking up my sd card,
the card works in my fiancee's sgs2
and no other card works in the o3d
never had this problem with my hero when i rooted that
only other thing i have done that might cause this is the fact i used Rom manager to install CWM....
seen threads about some other devices that have had the same issues.
Anyone have any ideas in fixing this?

Anyone know how to fix the sdcard security issue?

Ever since I upgraded from cm10 to the jellywiz rom I have been getting "Cannot access external sdcard for security reasons." I paraphrased because I can't remember the exact wording. Anyways anyone know why that is or if there is a workaround for it? I have tried multiple ROMs and even changed the kernel but it didn't work. I wanted to try to go back to ICS then back to another jellybean build but I am not sure how to do that. I hear it has bricked a lot of phones. Has anyone had this same issue and somehow fixed it? I miss my music.

Yeah it won't even recognize it when I plug my phone in my computer. It will recognize that there is one on my device but it says "blank sdcard or unsupported file system" It is the correct file system and it worked in ICS and CM10.

Sounds like you figured it out. Now have you tried formatting the card to see if it can be saved. Obviously after you back everything up, since your computer reads it.

Certain basics
You don't have cwm in a Rom zip
/data.. internal memory
/system... system memory.. this is where your Rom is
/boot... kernel is here
/recovery... independent of all other partitions and can be flashed either in Android using flash image binary or fastboot..
Google what other recoveries you have for your phone.. it should be in index /sticky for your phone in your forum thread.

if can't solve by clean flashing, it is high possibility that chip is faulty, this is hardware issue.

This thing happened a month ago and broke a memory card for me but the issue is that i have had the phone for a year and couple of months if its a hardware issue shouldnt it have happened earlier ?

you have answer ur own question..lol
think..memory card own do not supply own power to operate. the phone does. why your memory card broken? the phone brack it. why still the card be use in normal, thats complicated. intermediate current or voltage supply to the card may cause this. same principal as some phone can oc 1.3ghz some can't.
