First time CM7...fail...try again..

mkay o i'm kind of new to android and tonight i wet my pants cause i thoughy i bricked the optimus. I wanted to install CM7 but something went horribly wrong.
After I rooted and installed ROM manager I copied CM7 to my SD and installed. After it was done the CM7 boot screen kept looping. No way the phone was doing anything more than that.
The only other thing it would do was to sho a 'waiting for update' screen. After a lot of searching I mangaged to get stock ROM back by using smartflash, praise be...
Now that I know I can rescue the phone I'd like to know what whent wrong..any clues? Did I use the wrong build of CM7? I just used the latest of the 4th of july.
I want to try again but maybe some insight would be helpful, thanks...

Did you remember to tick the wipe data box in ROM Manager?

Well it would not install from rom
Manager (installation canceled by itself and ennded up with fresh install of LG rom...) so after that i did it from recovery. cant remember if i got the option to wjpe in there...

So when i installed from ROM manager i did xheck the wipe boxes. Then started installing from SD. The installation stopped, i have seen some sort of warning exclamation but i could not read what was wrong the message disappeared too fast. I think the 'wipe' was sucssesful though because all my apps and settings for stock LG firmaware were back to factory.

Ah ha.
ROM Manager and the stock ROM don't get on too well. Boot to recovery, wipe and install from there.

Assume you are using CWM recovery? It has the option to wipe on there if you look carefully so you can wipe it manually before flashing.

I tried again and it seems GB is now running cause I can see the battery icon on a different angle but it keeps givin me LG installation error messages after boot which i may ' forrxe close' but basicly nothing happens. Did i forget to wipe somerhing or forget to do smth else?

What recovery are you using? If it's 4.0.0.5, you might want to update to the newest 4.0.0.5, as the original one I built had some problems formatting.

The error messagel all seem to refer to LG apps or services. Device wont go beyond these messages.

I know, if it's what I'm thinking, they will have been left behind during the CM install, which shouldn't happen.

Ok so what do you think i should do? thanks for the snappy replies rusty.

Fyi, behind the error messages i can see a black background. The top bar with battery indicator is present, it charging. Signal indicator is there but has no signal.

Change recovery and flash again, either to 3.2.0.0 or the newest 4.0.0.5

this is what it looks like now. When i switch off and do volume down+ power its says waiting for S/W upgrade.

First i need to re-install syock again i guess? Wont do much else..

If you're getting software upgrade, you're letting go of power to early, keep em both held.
Edit: Or use 'adb reboot recovery'

hmkay im in recovery now thanks for that. It says 3.0.2.8
Signarure check enabled
Signature check disabled
Script asserts eneabled
Im not quite sure what you want me to do now. Thanks for your patience

Oh, 3.0.2.8 shouldn't have had any problems then, annoying.
Still, pik the wipe data/cache option, then install CM7

Im there thanks so much Rusty.

[Q] Stuck on LG screen [Solved]

Hello, this is my second post here though I visit this forum quite frequently.
I have a p990, and I have encountered a very strange problem with my phone:
Until yesterday, everything was normal, and every couple of weeks or so I installed a new/updated rom via CWM without any problem (usually).
Yesterday I installed the CM7 Kang from Ricardo, and this also worked well. However, when I tried to install my previous rom again (Gueste 3.1, after 3 wipes of course. The reason I didn't go back to a nandroid backup was because of problem in making the last backup) it got stuck on the 2ng LG screen. the buttons are lighted when I touch the screen, but even waiting 30 minutes doesn't change anything.
Since then, I tried to install many different roms (the latest CM7 nightly and some others), and all gave me the same problem. The only things that I've been able to do in order to boot successfully was to revert to an old backup that I had, or to install MIUI, which did work for some reason.
When I tried to install the same version of CM9 again, I always got a boot loop.
Any idea as to what could cause such a strange behavior and how can it be fixed?
Sorry for the long post, I just wanted to give as many details as possible, and I'll be happy to give more details if I can if there are things that I forgot.
Thanks,
Beorn

Try this: go to recovery > mounts and storage and wipe system, data and cache, and flash your rom.
If wiping system doesn't work neither, catch a logcat when the phone bootloops

This fixed the same issue for me.
Wiped everything and flashed CM9. Works great (but battery drain is incredible!!!)

Solved!

Thanks, I did this, and now I was able to boot again with Gueste 3.1 (I'd rather wait for a bit more stable and mature version of CM9).
Actually, I did this thing twice, and it still didn't help, and in the third time I tried to make a logcat (I'm rather new to this logcat thing), and while trying to boot and make a logcat at the same time it suddenly started workind
I just hope that it will stay good now, and that I won't have this problem again in future flashes...
Thanks!

Lg bricked?Noob mistake..

Well, i wanted to change my rom, CM 7.2, with DjangoManouche 1.2 and used the rom below..i backed up, and when i started flashing, it said that"this is not a ROM"..i..kind of panicked and after a minute, when i seen "nothing moves" i removed the battery. When i tried to start the phone, it only shows the LG logo..but does not boot(i waited for just 1-2 minutes..). I hope someone could help me.

I recall reading something about using NVFlash to force the stock rom on and allowing to recover from a bricking.
I'll defer to someone with experience in fixing bricked phones though.

Thank you...now..it wont even start, even when i plug-in the charger..it had pretty low battery..i am pretty ducked..

You have to reflash it with KDZ recovery method. Look up google and you'll get it working. I did this the first time too (what a bad joke to say "this is not a ROM")...

I'm sure you can still enter Cwm if you hold down volume- while pressing power button until it the Cwm menu appears.
Sent from my Optimus 2X using xda premium

First of all, don't worry, O2X is pretty unbrickable...at least in the level you're messing with it!
If you have recovery installed, you should be able to reboot into recovery : press and hold vol down button, then power button until you see blue halo of LG. before that, download another ROM and put it in your external SDcard. Flash that ROM.
You can also download and flash the original firmware of LG by using smartflash. You can find those in ANDROID DEVELOPMENT section!
Also check KDZ recovery!!

Thank you..it worked with recovery mode..i had back-ups. I got a bit scared because when i pressed vol_dwn+ shut down button..after i release the 2nd button, it turned off...but i menaged to make it. Again, thank you for help.
====================
well, today i tried again to install a new rom(temasek's cm7 last build)..but i couldn't..after it is installed it get's into boot and stays like that..i tried to AOKP and it worked..my backup also worked...i just can't get it, why these roms won't work?

The common mistake for new people is that they restore entire nandroid backup after flashing ROM. CWM doesn't have option to backup DATA only, so you have to restore DATA from nandroid backup using Titanium Backup etc.
Try this:
1. Restore into fully functioning ROM(+data) if you don't have already
2. Reboot to recovery
3. Format /system
4. Flash new ROM
5. Clear cache and dalvik cache
6. Check if phone successfully boots
7. Flash Gapps if needed.
8. DO NOT DO ANY RESTORES AFTER STEP 1!!
9. If it doesn't work out, try another ROM. There may be some error with the file!!

[Q] Custom rom went wrong (LG optimus 2x)

so i finally decided to root my lg optimus 2x, after a few tries, i finnaly did it. so after that i went to the google play store to download the app Rom Manager, after it finished installing, i went deeper into the app (Rom Manager), and found out that i could just download and install a custom rom directly from my phone, without any pc connectivity. so i choose one that was written stable on, after the custom rom was downloaded, i clicked on the icon in the notification tap to install. there were some preferences i could choose, so i decided not to backup the files from my build-in rom. after that, the phone rebooted and my phone was showing alot of text informations, and in the background of that the Rom Manager icon was showing. after the installation was done my phone got turned off. after that i decided to turn it on (obviously), and it just got stuck at the LG logo in the beginning.
so the question is, what do, i do now? i have tried everything.

please move this to questions and answers

you should look into more what you need to know, need to do before flashing a custom rom

well, you either try flashing a Stock rom via Smartflash and if that doesn't work, you'll have to use Nvflash, but don't worry, your phone is fine, there's nothing to be afraid about.
Next time you try a rom, you migh want to root the device, install cwm, then make a backup with the app Titanium Backup, after that, you go into the cwm, wipe as needend and install the rom. Do read the guides there are about flashing, because things like this could happen if you don't know what your doing.
If you have done a Backup of your Rom you just simply click restore in cwm and everything would get back to normal, but since you didn't, you have to use Smartflash.
But anyways, if I were you, instead of using Smartflash as my first choice, this is what i would do:
1.- Download a CM7 rom (or any other rom i like) for the O2X in its page with the gapps (google apps), if you like Stable versions, then go for it.
2.- I'd put that rom in a microsd card directly from my pc and then put that microSD card on the device.
3.- I'd go into cwm by doing this: While the phone is off, you click: Volume down + Power button at the same time and wait until the secong LG logo appears before releasing them.
4.- I'd do the firsts 2 wipes it shows there: Data wipe/factory reset (as I already have a Titanium backup) and Cache partition wipe
5.- Go into "Advanced" and wipe: Dalvik cache and Battery stats.
6.- Go back and choose: "Install zip from SD card" then "Choose zip from sd card"
7.- Locate the file and apply it
After that you'll see that "lots of text information" you saw the first time, that's fine, just wait a little, after it's done simply click "Reboot system now" and wait a little bit for the Rom to charge for its first time, if everything goes fine, you'll have CM7 installed and your phone will be functional again.
If you like the Rom, then look for tutorials so you can configure it the way you want and flash the gapps.
Hope this helps you
I think that the reason you got stuck in LG logo, was because you were installing a rom that doesn't automatically convert the EXT3 partition into EXT4 or something, or maybe what you installed wasn't a rom, i don't know, just be sure to check a little more in the future Good luck!
Note: not all roms require to flash gapps, only Cyanogenmods and some others.

Inviato dal mio LG-P990

Phone does not show battery charging status

Hi I am using CM10.1 nightly dated 8-Jan 2013; with the latest matching gapps file
(10.1-20130108-NIGHTLY-p970.zip)
I have followed the usual practice (wipe data/factory reset, wipe cache, wipe Dalvik cache, wipe battery status)
I always select the Status Bar to show battery level as circle with percentage. (I did that with CM10 and now CM10.1)
But this nightly has a peculiar problem: The phone does not display that it is being charged.
Two different displays are affected at once:
1. In the status bar (at the top of screen), the circle should rotate when phone is charging. It does not.
2. When the phone is locked, if I press the power button, the lock screen should show "Charging xx%".
Instead, it shows "Discharging xx%".
I guess a common mechanism for both these displays is broken.
The CM10 used to work fine.
Since I am not allowed to raise a bug for nightlies, I am raising it here.
In case any information is needed, please let me know.
Thanks in advance!

I used the one from 8 January but haven't encountered your problem. Like you i also use the circle mod and set the option to always show battery status in lockscreen. Also no problem with the nightly from 10 January.
Is it charging at all? Do you have this with other roms as well and have you tested this?

Yes, it charges normally (the charge percentage increases normally). But at the same time, the lock screen says "DIScharging XX%", and the circle in the status bar stays steady (no rotation).
So far I have flashed 3-4 nightlies in CM10 series. In all of them the display worked just fine.
I would like to mention a fact: I used the wipe routine only for the first CM10+gapps. For the subsequent nightlies, I did not wipe anything (just flashed the new CM10+gapps over the older set.) It simply updated some packages. I never had any issues.
In fact, I flashed the 10.1 also like that (old habit), and found the problems mentioned here. So I followed the wipe routine and then flashed the CM10.1+Gapps once again. But the problem remains.

I had this problem time ago..I am not sure about the way I resolved but I think this is a problem relatet to the custom theme..
Do you have some custom theme installed?
Try to change the UI theme (Settings-->theme) or if you do dot have one (different by the stock one) download it and set the theme.
Then reboot in CWM, whipe cache+dalvik and fix permissions.
Let me know if it will work..

Sorry for the late reply!
I must confess that I don't know where to get a decent free theme. So I searched around and came across a theme called Crystal 2.
I installed that, and then encountered "Unfortunately the UI has stopped working" messages (several-one after another). I also got a few "Unfortunately Trebuchet has stopped working" messages also. Actually the download page pre-warns the users about this possibility, and recommends a routine: Change to default theme>Reboot>Change to the new theme>reboot. So I followed that.
After this I rebooted in CWM, wiped cache, wiped dalvik cache and fixed the permissions.
Still both the problems remained: The lock screen does not say "Charging", and the percentage circle in the status bar does not rotate.
I reverted to the default theme. Yet the problems still remain.

I did that TWICE (including complete wipe, which resulted in re-downloading of all my apps, and also getting back all contacts from my Google account).
However, that did not resolve the issue.
I think this is a bug, after all. Several other people are facing it too!
Hope the developers take a note of this. (I can provide any debugging info as required).

AW: Phone does not show battery charging status
When i just recently had the pgroblem, i did the following. Flash a stock v30 ROM, do a factory reset from hidden menu, flash only v20 bin file with cwm patch, once in recovery, start setting up the rom again. Dont use a backup though... when I restored mine, i had the same problems afterwards

Thanks for the tip!
I just noticed that you mentioned v30, but I remembered having V20G.
So I tried to check it in my phone, and found a problem: Earlier I could see this firmware version in my phone setting.
But after installing CM10 (and later CM10.1), this setting is no longer visible.
So I Googled for a solution, and found that version number is embedded in the Baseband number.
Well, my Baseband number is LGP970AT-00-V20g-SEA-XXX-JUL-03-2012+0.
I also noticed that the following site lists a V30C for India. (I am in India).
http://lg-phone-firmware.com/index.php?id_mod=1#india
Does it mean I am indeed using V20G, and therefore an outdated firmware?
Just to confirm, (so that I don't mess up) is the following procedure ok?
A. UPDATING THE FIRMWARE:
1. Download USB driver and LG Mobile support tool from here:
http://www.lg.com/in/support-mobile/lg-P970
2. Install both on PC, and connect mobile to PC, to update the firmware.
B. UPDATE THE ROM:
1. Download the V30C ROM from: http://lg-phone-firmware.com/index.php?id_mod=1#india
2. Place it in the SD Card.
3. Reboot into recovery mode to run SWM, and select the "Install zip from sdcard" option, and select the V30C ROM.
4. Without exiting from SWM, select the "Wipe data/factory reset" option.
5. How do I flash just the V20 bin file (How do I avoid installing the whole V20G zip)?
Do I extract the bin file first from the zip and copy it to my SD Card?
6. In SWM menu, select the "Reboot" option and let the system restart.
********************
Thanks in advance!

AW: Phone does not show battery charging status
Wrong procedure. You need to extract bin and fls files from the downloaded .kdz file. Then you need to flash it as i said above using SmatFlashTool.
Plus you need to boot up the flashed v30 ROM, go to dialer, type 3845#*970# and from that hidden menu dp a factory reset. Yes it is different from a wipe in CWM. Then shut down your phone, bring it to download mode, flash a v20 bin file, once in cwm, do a factory reset, install any ROM you want, be happy

I am not well-versed in CM ways, so had expected something like this.
Here is the revised take on what I need to do:
1. Update firmware (follow all steps of Part A).
2. Download the V30C and V20G ROMs from: http://lg-phone-firmware.com/index.php?id_mod=1#india
Now extract the bin and fls files from the V20G ROM (.kdz file),
using the technique mentioned here: http://forum.xda-developers.com/showthread.php?t=1692191
Place all the files in the SD Card.
3. Download the SmartFlash Tool (as described here: http://forum.xda-developers.com/showthread.php?t=1448803)
4. Reboot into recovery mode to run SWM, and select the "Install zip from sdcard" option, and select the V30C ROM.
After installation, reboot to CM10.1.
5. Select dialer, enter 3845#*970# and press on the handset button (to actually enter the string).
From the menu that pops up, select "Factory Reset" option.
6. Now run the SmartFlash Tool (as described here: http://forum.xda-developers.com/showthread.php?t=1448803).
(The only difference is, point to the path of the bin and fls files that were placed in SD card in step-2)
At the end, the phone reboots automatically.
********
BTW I am facing another problem that could block the execution of the procedure listed above:
I am unable to connect my phone to PC through USB cable. The phone is not detected at all.
(It used to work in CM10, but problem started after I installed CM10.1).
I have seen that this problem is posted by a lot of people, and none have found any solution.
To transfer any content to the CD card, I actually swap my SD card into a Nokia feature phone and then transfer the files from PC to card.
Once that is done, I place the SD card back in my P970.
But I think this problem with USB port is going to create trouble for me.
Could you help with this issue?

[RESOLVED]
My further experiments were stalled because of my issue with USB connectivity (which turns out to be a driver issue, as the LG service center is able to connect the phone to their PC perfectly).
But I am glad to report that I installed the latest CM10.1 (dated 20130211), and both issues are taken care of.
I did see the release notes this week which talks about changes in charging logic.
Maybe this was the reason.
ISSUE IS RESOLVED.
Thanks for all the support, guys!

Can I add a question about device off charging? It seems to show full battery icon even when the battery is not full. Is that normal or should it be animated or blinking?

Hi,
Since the issue is marked "RESOLVED", people having the same issue may look at the end of this thread to learn what solution I found.
They will be confused to see a totally unrelated issue being discussed.
Please initiate a different thread.
Thanks.
