[Q] One Week trying to save a P920 and Failed [ Help Appreciated ]

Hello Everyone,
So I've been dealing with a P920 for the last 7 days trying to Flash it and it's not working.
1- Device is booting to Android but all applications are crashing ( unexpected error com.x.x ) force close.
2- I tried LG recover mode, phone flashed but once successful and rebooted, same error upon loading desktop.
3- Tried rooting the phone with SuperOneClick2.3 ; Rooting successful, upon reboot, rooting is lost
4- Downloaded KDZ original firmware V21A Europe based from lg-firmware site and used offline installation ( shttps + modified host file etc..) . Installation successful and flashing is OK; rebooting = same error on startup.
5- Downloaded firmware V10B and flashed it successfully. Rebooted, phone version is still showing V21A !
6- Rooted phone + installed CWM -> successful, rebooted, it's gone.
Now this is the first time since 10 years that I get into such thing and the device is getting me on my nerves.
Any idea or advice is much appreciated!

Well
Looks like a hardware issue. ROM, RAM, Internal memory. U need to find a way to delete partitions and re do them somehow. Have no idea if there is a software for that. I had it for my SGS. It should help.
Just repartition whole internal memory.
UPDATE:
Here you go ! Good Luck ! and tell us did it worked for you

Remember not to switch internet with external memory or u will brick it totally!

Great, I will give it a try thanks.
Do you think I will have to delete all partitions and create them again ? or I should only specific ones ?

Have no idea. Try to make some research I don't want to give you wrong answer. Should be only one where rom data is, but I'm not sure.

Hello MinedSafe; As I mentioned earlier, whenever I root the device and reboot, it's not rooted anymore. It is not possible to install CWM ( changes are not applied )
I have managed to root the device and tried the parted command, I get command not found.
I have noticed that once I get into the stock recover and wipe everything, I do not get the first welcome screen to setup the device, it's booting with the same error.
I have started to lose hope. Device is no longer under warranty

Have you try to recover it from LG mobile support tools ?

Yes, I tried, it downloaded 404 MBs and flashed the device. When it boots, it still goes into the menu as if i have not done any update. No first setup screen and the crashing application error shows up.

i try everything but nothing respon.

It looks like the partitions are damaged or eprom/rom ( no commands ) memory is gone. So the only way is to send this to LG service where they can upgrade/rapair with their 'hardware' tools. If you try on you own you might get to a stage where even they wont be able to fix it.
What kind of software you where putting in to it ? Froyo or GB ?

Another person, so its now more likely then when upgrading the partition table was screwed up. It could be a mistake in addressing the memory when flashing.

2.3.5 Europe open V21A !
So basically this is what we call " bricked device " ?

Yep, sorry to say that. Depends on where you live, but the cost of repair should not be to high.

Is someone here know what is the adress to send my phone to get fix in europ?

Thanks for your help bro but even when I flash stock ics i can't get sim to work
If i just flash only the stock ics i get invalid sim card
And when i install cm10 over it the problem is still there

try these:
--> remove sim card and place it again correctly (works sometimes)
--> when you enter the CWM make sure you completely wipe your data includes- wipe cache, wipe /system, wipe dalvik cache, format /data /cache and then click on reboot the system now and remove the battery. go back to flashboot mode and flash the ICS firmware and i hope this might help coz this is what i did to my phone

Nothing bro! still the same
my phone asks for the sim password "PIN" and it only accepts the right pin code, what means that the phone reads the sim card
but i don't know why there's no signal and appears the message "invalid sim card"
I've tested many different sim cards and nothing solves
if I did something wrong
theoretically I just need to reflash an stock ftf and everything should be ok
but that doesn't solve the problem

it is because of trim area damage
you should have backup your trim area before unlocking bootloader
trim area, google it

[Q] Help!! IMEI NOT WORKING

Hello all,
I have a KArbonn A2 phone with gingerbread.... i tried flashing the ICS firmware of KArbonn A2+ since i knew both phone have exact hardware with no change at all. After flashing ICS it was runing all good and smooth but the only problem is i couldnt get the network on it. It shows the SIM name
but always NO SERVICE .. i flashed back to original now but is there any tweaks to make network work on ICS?? It would be great if all those users like get to upgrade to ICS since it is one of the most cheapest android phone. Thanks

net work not working
mybe you can try this:
press *#*#4636#*#* and then. choose the right model.
if you have GSM sim card so just switch to gsm if not switch all.

Your issue is that your efs partition got corrupted and this can only be fixed by the OEM legally. I would send it in for repair.

Your problem is that when you are flashing a new rom your imei number is getting deleted and hence you are not able to connect to any network. You have to take backup of your imei before flashing a new rom. You should check this link out

Invalid IMEI.

After flashing a Rom, my phone didn't recognize my SIM. Thinking it was a bug,I restored my old Rom. But then also my sim is not bring recognized.I did a factory reset yet no use. Please help me out.
thank you.

Bro wipe everything and then flash any rom for xperia c...
Then select the network in gsm mode...
If still the problem persist then ur sim card maybe not working...
Try exchanging sim positions.

Well, at first I tried to flash vanilla Rom to my Xperia c. Then after flashing it, I booted up. But the rom had many bugs like no navigation soft keys, SIM card not detected and so on. So I restored my latest backup of my phone. Then I booted up, to see my SIM not being recognized. So I triedto restore other backups I had, but no use.I did a factory reset, flashed stock Rom, but no use. This ous what happened.

[Q] Help! OPO cant detect sim card & restart every minute or so..

Before : CM12S YNG1TAS17L rooted.. Works perfectly fine.. perform nandroid back up using TWRP before flash kernel. until I flashed Franco kernel r42.
After : Upon 1 boot after flash kernel, screen colour turns very unsual. The phone cannot detect simcard network at all. I've tried friends Simcard and several different carrier network. All cannot detect the sim card. & the phone freezes for 1-2 second then restart by itself its been doing this everytime I boot up. When I shut down the phone, it automatically start it self. I've tried restore back nandroid backup , wipe & install new stock rom or custom rom, everything doesn't work. Not Simcard detected, freezes and restart by it self no matter what rom I've installed.
I have no idea what to do... :crying:

Why not? There's information all over the place that informs people that it's crucial to have a backup of your EFS partition. The backup is the best way to fix your problem, with you don't have one your chances are slimmer. There are a couple of threads here in the q&a section and in the general section that propose fixes, track them down and start reading.
