Ok. Tnx ..

You can remove the battery IF YOU WERE FLASHING BASEBAND ONLY
then put battery back and press vol up + back + power and phone will go in emergency mode
disable all lg modems in device manager, then flash baseband again and it will work

I remove battery ~10 times, and phone always automatticly go in emergency mode when i back up battery, but device is not recognize by tool like a LGMDP-v1.5, lg studio kdz updater on computer.

1. remove battery
2. put battery back
3. press power button+ volume up button + back button together
4. keep buttons pressed and phone will go in emergency mode
5. now lgmdp will recognize device

@TheAndroidGeek

What next?

Disable modem drivers (LG) in Device manager!

In Device Manager is disabled only LGE Virtual Modem because he is only there. But error is still there in lgmdp.

Hooo ...
I back phone in life with this tutorial: http://forum.xda-developers.com/showthread.php?t=1197111
Thanks to xzet2 for that tutorial.
Now, i installed this ROM: http://forum.xda-developers.com/showthread.php?t=1818219
But i dont have service again (no signal - baseband is unknown). With android 2.2.2. is all ok (have service, baseband v10e is show and all work ok) but i want ics.
I trie to flash baseband to P500-v20G but lgmdp dont see phone when this ics rom installed. When installed android 2.2.2 lgmdp see phone.
In Device manager LGE Virtual Modem is disabled.
What to do?
Does ok to install ROM with android 2.2.2 and then flash baseband on v20g version and then install ics, or what?

And again hoooo ...
I start phone in emergency mode, run lgmdp and flash baseband. That all work 10 seconds, and wala ... now i have new baseband and ics rom.
Thanks!

is there any hope to bring it into life ?????
Please help me
p.s :
1. KDZ UPDATE : I TRIED V20D.00.KDZ FILE . it show " upgrade error error code =6" .
( tried all three mode " DIAG, EMERGENCY, CS_EMERGENCY) but got same error for all the mode option.
2. lgmdp : upon connecting doesnt shows any thing in NV backup .

OMAP4430 appears and disappears again and again

Hi, its been almost half a year now since i bricked my O3D, im still having problem solving this. I'm still newbie at this so i dont how to solve it. Still stuck at where you fastboot the omap thingy. I cant get into download mode i've tried all sorts of ways and still no luck. Did install OMAP4430 and after that the fastbooot one, tried holding vol+ and plug the cable and no logo appeard on my screen its pitched black only the search/back/home/menu buttons lights on. Then after a minute or less its turn off and the OMAP4430 in the device manager started to appear and disappear all the time, also i cant seem to find the LG port device on my device manger Help?

for pc driver installation. It is rather fiddly, so proceed slowly and read all details carefully. Once it is correct, however, you can use LG Flash Tool, Fastboot, ADB, or whatever for this device.

did all its says from the top still i cant find the LG port and my device manager keeps on refreshing and the OMAP device also keeps on appearing and disappearing.
Btw i did went(last year ago) to LG costumer service and after a week they said that the main board is the problem, and it cost more likely 40-50% of the original price of my phone Up until now im still hoping for my phone to be fixed.

I would try again; there are a lot of little details there that are easy to miss the first 5 or so times trying to do it. Rebooting pc between each step, for instance. You must be logged onto pc as administrator also. It took me some time before I was able to install the drivers correctly and that was before I wrote it all down in detail.
If it really is the board (I picture a scenario where they want to sell you a new phone) then none of this will help. However, the omap4430 blinking on and off tells me it is trying to connect, but is not installed correctly.
Take your time with each part and carefully check every detail.

omapboot and sw are two different modes.
the "LG port device" appears only in sw mode
omapboot:
you need omap for flashing the custom bootloader
enter the mode: remove the battery and plug your phone to usb while holding vol +, for me its working also when i just plug the phone without battery. if the device is appearing to fast in the devicemanager plug the battery into the phone, and the device should stay and you can install the driver,
sw mode:
is needed when flashing wit lg flashtool or smartflash etc for flashing stock roms or simliar.
you can enter that mode:
plug your phone to usb while holding vol+ with battery insert, and keep holding until the phone screen shows sw and some korean letters.
now you can set the port to 41 in the device manager

yes, in the sw mode, thats where i got stucked did hold vol+ w/ and/or w/o battery (tried both) no logo and korean letters appeared on my screen totally pitched black only the search/back/home/menu lights up after that the omap keeps on appearing and disappearing. Tried different cables btw im using win8 and i also tried fresh start on other laptop's of my friends. It's very frustrating

anyone had some success here? I have as well OMAP device on-off, I can go to SW Upgrade mode (no Korean letters though) and to stock recovery.... Tried LGFLashTool2014 (but it crashes on "Read Phone information) and "Flashtool"-Tool, which can enable fastboot and flash uboot, etc. But to no success...

HELP! ROM Manager bricked my O3D - Is it fixable?

NOTE: Before we start, I have now googled it and in hindsight I probably should of left RM alone!
Anyway as the title states my O3D seems totally goosed! I selected the recovery flash in ROM Manager for P920, it rebooted and all it does now is show the logo for a second, vibrate then off. I tried the usual tutorial stuff...
Power button, Vol up battery in - it comes up 'USB Device Unrecognised' and then It also keeps popping up 'Unknown Device' however when I click on properties every entry is 'Unavailable'
Power button, Vol Down, battery in does nothing (tried it a million times)
If I do...
Power button, Vol up then apply the battery - Device Manager finds... 'LG Mobile USB Modem', 'MAP SMS' (Other Devices) and 'LGE Mobile Composite USB Device'
No sign of OMAP44xx so the flash tools don't see it... strangely LG Mobile Support Tool sees the phone and tries to update it however it says it has the latest firmware, when I use the update recover option it gets to 15% but then complains that it can't communicate with the phone.
Is it dead? :crying:
Any help would be much appreciated.

dont worry. its not dead. has happened to my phone a trillion times ..
all you need to is try as below:
1. without connecting phone to usb first hold down 3d button then volume down and keep pressing power untill it starts up and then off again , then release all 3 together as it is off and repeat (remember first 3d then volume down and then power). this time just let the power button go on lg logo but keep pressing the other 2.
2. if this doesnt work, then easiest method - download omap4boot for optimus v1.21 or all in one p920 v1.3 by XDA, remove battery, only press down the volume up button and while pressing connect usb. make sure you hear 1 ding of connect , 1 dong of disconnect then 2 dings of connect. after this the ding dong should end .. if you have all drivers installed , then it will install omap drivers. a window will pop up and everything will have a green check. once it does that you can install a custom recovery twrp or cwm using fastboot . boot into recovery and flash a rom.
still if doesnt work, have patience, post a reply and will tell other steps to proceed with .....

Thanks for your time RVBSD, unfortunately (although I will keep trying!)
In No. 1 - I get the first logo, but when I re-apply the 3D/V and power, I don't get the second logo.
In No.2 - I get the first ding/dong then just 1 ding, no sign of Mr OMAP! - I'll keep trying though.

Once u get the second ding and then this music stops, Open device manager. Look for lg usb modem and disable it. Then look for omap44 something. The device manager may be refreshing quickly. Somehow i had a chance to right click on omap device and chose update driver. Select manual and choose omap.inf from the folder that u have to download as per my previous reply. Restart computer and check again.
Alternatively you can install all inf manually, right click and install, before connecting the device.
Let me know

Again, thanks again for your input but I am still no further. I manually clicked the inf and it said it installed fine... but nothing changed in Device Manager. I then attempted to 'force' the driver on the unknown device, however after it installed it returned a 'Code 10' error... unable to start.
Even tried the service software 'LGNPST' but it couldn't even connect to the port! ho-hum...

i tried it again. even on my computer it didnt take the omap drivers this time.... strange .....
but i could install fastboot, then installed cwm recovery . then flashed a rooted rom and its working ...
1. Turn off your Phone, pull out battery.
2. download omap4boot-for_optimus-v1.21 (run "start_fastboot.bat" (it will wait until phone connected)
3. connect phone with USB cable without battery, the usbboot will start
4. insert battery while the usbboot is waiting, it gives 5 secs only
5. unplug USB cable the LG logo will appear with fastboot on top
6. download the attached files to your desktop and extract
7. open cmd and in cmd navigate to fastboot.exe location, where ever downloaded
8. run fastboot.exe from cmd and choose the cwm file to be pushed to your phone
command : fastboot -s flash recovery recovery-clockwork-6.0.1.9-p920.img
9. reboot device into recovery , try to wipe cache and factory reset and try to reboot
if this works it will take you to existing installed rom, then you can reboot to recovery and flash Su_Bbox_1.20.2_gazhead_signed.zip to root it
10. else copy a custom rom to sd card , insert in the mobile , reboot into recovery and flash the cutom rom

PLease help
CAn you tell me how can mount recovery partition

Neffos X-1 stuck in bootloop

Heya folks,
I have just attempted my first time flashing TWRP on my TP-Link Neffos X-1 following this guide: https://rootmygalaxy.net/twrp-root-...nd_Install_TWRP_Recovery_On_TP-Link_Neffos_X1.
Its looking kinda grim. It starts with the orange state Message and that the device will boot in 5 seconds, however after that it starts with an infinite bootloop. I also cannot access the Recovery (vol up + power), for it simply doesnt work anymore after the guide. When I plug it into my pc, it will automatically start with the bootloop (I can shut the phone off with vol down + power).
Attempting to get into fastboot mode over ADB (adb reboot bootloader), returns with the message error: device '(null)' not found. I think that is due to it not being recognized in the device manager(it doesnt show my phone anymore but unknown device). I tried to install the phone driver for the uknown device, however that keeps failing. I think its due to the phone permanently connecting and reconnecting to the pc.
So I'm wondering of what to do. I guess the biggest issue is that the drivers are not recognized, but as long as the phone keeps on restarting every couple of seconds i doubt i can properly install the driver. You guys got any ideas?

My guess is you haven't installed on Windows PC the appropriate Android USB Driver matching the device

I mean the appropriate USB driver had to be there for me to flash it with the TWRP in the first place, right?

Think I clearly said that the additionally required USB-driver has to be installed on Windows PC.

I have this one installed https://rootmydevice.com/download-neffos-usb-drivers/, is this the additionally required usb driver?

So far, despite what driver I pick for the device, it shows the code 10, device couldnt be started - probably because it never gets past the starting screen but keeps rebooting

Try this TWRP file: TWRP_3.2.3_NeffosX1_TP902A_by_kiruha_21.img

The thing is, I cannot flash anything due to my phone constantly rebooting while inserted in the pc usb-slot. Neither ADB nor my device manager recognize the device and as mentioned before, I cannot install any drivers

Some MTK devices has this: Press both VOL+ & Power buttons. Only remove 2 buttons when you see Bootloader mode (recovery; fastboot; reboot system) or directly in the Recovery mode. Now you can use fastboot.
With the SPFT you can use same tip above. In the SPFT choose DOWNLOAD and plug USB device. Process to flash stock ROM or stock recovery.img & boot.img start.
If not start pugging USB: choose DOWNLOAD - press VOL- and plug USV device. You can try with buttons like only VOL- or VOL+ or combo buttons VOL+&VOL- or VOL-&VOL+ or other button combination.
You can try FIRMWARE UPGRADE too.
That's depend about LOCKED or Unlocked bootloader process that you made before actions!
If you unlocked bootloader so only need patience. If not so that's no good.

Bootloop after trying to install LineageOS 18.1

Hi,
I'm having troubles after following the guide here - https://wiki.lineageos.org/devices/guacamole/install
I initially had stock Android 11 with latest update. I've followed the instructions, all went well until I rebooted to system. It just tries to boot for a few minutes, then it restarts and does this again. Doesn't seem to boot.
Is there a way to fix this?
Also, would be possible to get back to stock rom and how?
Thank you in advance!

Managed to fix, in the end. Was a real headache.
If anyone is having similar problem and they have to unbrick their phone, I suggest this thread - https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.3954325/
Follow the steps in that thread. To enter EDL mode, you will have to turn off your device, hold Volume UP and Volume down (without power button) and while holding insert the USB cable into the phone and into your PC. By doing so, it will be detected by the computer and will show up in Device Manager.
The most annoying issue I had was the phone was connecting for a few seconds, then disconnect. What worked for me after many many tries was using a newer image, mine being an international device I used 10.3.8. I opened MSM from the 10.3.8 package and Device Manager, connected the cable to the computer, but not to the phone, I've pressed volume up and down, connected the cable to the phone while holding volume buttons and as soon as Qualcom driver showed up in Ports (COM & LPT), I hit start on MSM.
If it still gives you the error "Sahara Communication Failed. Please try again after power off phone" try with a different package version, for me this one worked, but before that I've tried with a different one and I was getting this error.
Hope it will help someone, at some point. I know how frustrating it is and if I helped you be less frustrated than I was, that's a win.
