[Help] system reset when reboot, stuck on LG splash screen

[feishenfeng4294]

I formated the system, boot and
I flashed xionia_cwma_12518.4 to the lg optimus v.
now there is not rom in the system, and every time I reboot, the phone will go through
android system recovery
do not pull out the bettery
formatting data:...
formatting cache:...
factory reset...
rebooting...

and stuck on the lg splash screen.

when the phone is connected to usb, the computer is trying to install the driver, but because it automatically go throught the process described above, it will disconnect before the driver can be installed.
so adb cannot see the device.

what should I do? thanks.

I had this same problem
There is a thread called
[FIX] ADB method to break factory reset bootloop by wiping /mtd8
By bigsupersquid
I fixed mine like this
Sorry cant give u a link im on the mobile site of the forum

**EDIT** sorry didnt read the part that adb did not reconize it

 

[arnold1997]

Leave the phone on then connect to computer then check of adb sees it wether or not if the drivers installed

thank you. Tried this.
in command line. it shows:
Erasing 128 Kibyte @160000 -- 91% complete
/sbin/sh: adb: not found

Now the recovery is gone, only the lg splash screen left

I guess the phone is now without a recovery nor any rom.

 

[arnold1997]

Does adb still sees tge device?

 

[arnold1997]

Also have u tried booting into recovery?

 

[feishenfeng4294]

adb can't see it anymore. the phone does not even trigger the usb connection to pc.
cannot boot into recovery also.

 

[clodfelterac]

try reinstalling the drivers on your pc... perhaps that will help... im pretty sure youre gonna have to push new recovery and rom via adb to save your v... but... it CAN be saved!...

edit: go to leslies2012ov reference guide... post#10... hope this helps...

Try this
Take out the battery
Press the recovery combo (Home+Volume Down+Power)
Then while holding that insert battery again
And maybe boot to recovery

It worked!!
In the Xionia CWMA v1.2518.4 now.

should I replace the recovery to something else using adb now?
(I installed xionia cwma in order to break the boot loop ealier)

or what should I do next?

 

[arnold1997]

Good!
Now do this:
Wipe data/factory reset
Then wipe cache
Then go to advanced and wipe dalvic cache
Then flash ROM
Then flash gapps(if needed)
Then reboot
Post the results

 

[feishenfeng4294]

keeped the xionia, and installed IHO rom. everything seems fine now. you guys are awesome

 

[arnold1997]

Now reboot normally just to make sure everything is fine
Glad i could help

Now you should flash a rom, just DON'T factory reset.

Edit: to late
