[Q] GT540 stuck on android screen HELP!!

Hi guy's
I have a few questions I'm really hoping someone could help or point me in the right direction..
I have looked for answers for a couple of days now when I had some free time but haven't found anything.
1. My brother's GT5-40 OPTIMUS is stuck on the android screen. Prior to it happening it was sitting idle. Would a hard reset fix this?
2. He would like to upgrade from 2.1 to maybe GB is it possible? And where can I find the correct thread to do this?
3. Is there anything I can do to optimize battery power?
I hate to annoy everyone with my questions but I'm new to this kind of thing I've only just started flashing my xu and exploring these things so don't have much to go on and would be grateful for any help at all.
Thanks for looking.

UPDATE:
I tried a hard reset - didn't work.
Tried phone recovery on kdz updater : nothing.
Not sure what's next.

you don't provide much info , but first, can you get phone connected to pc ? (example in download mode)
if you can then flash from kdz update is possible. (use this tutorial : link , if no go then try different phonemodes in kdz updater)

Hi
I can get into download mode but nothing else. I tried to flash in kdz bit didn't work for me all the modems seem to sit idle. What other info would be helpful? Sorry I'm in unknown territory with this.

It's been over a year since I've used KDZ, but if not mistaken you have to use fastboot (power on while holding camera) with KDZ. If you can get into fb mode you can try to get KDZ to work. If the modems remain idle you may need to reinstall drivers. If you can get to fastboot you can resolve your problem. G'luck

Hi
Can't get into fb mode I did try a few times. I guess I've hit a wall with this.

fb is not visible , it apperas as black screen ,, but you can confirm that with cable connected to usb (in androidsdk : "fastboot devices" )
also, try that method : unplug usb from phone,power off device (eg. battery out, to be sure), put kdz updater ready, and then plug usb cable and immedetly start kdz updateing... (i remember, i've had same problem and then somehow i've got it working with that method)
also try several times.
also, i cant understand why kdz updater doesn't work in download mode , are you sure that u have all drivers installed correctly ? tried several modes in kdz updater ? (cs_emurdiance and etc.)

I'll give it a try and report back. I really appreciate this. Kdz didn't seem to work I will double check all the drivers etc and see if I've missed something.

So I tried fb mode, nothing like what you describe happens when I attempt to get into fb mode. I double check that all kdz drivers were there -one was missing so when I got that I was intact able to flash the phone, but it made no difference, I get the LG logo on start up then it goes to the android screen and no further. When I try fb mode following your instructions I get the boot up as described above, I tried it a few times but always the same result.

did u flash fastboot enabled rom ?

Yes used the French v20b couldn't recover the phone even with that.
Sent from my ST25a using xda app-developers app

Enter the download mode (volume - and power button)and flash the official rom(should be in 7z format)

I tried downloading the official Rom but couldn't get it all the links are not working, well all the ones that I tried. Do you know of any? I'm really grateful of all the help.

with this tutorial I repair my gt540 [ROM][Gingerbread] 2.3.7 | CyanogenMod 7 | SwiftDroid ASIS| Mur4ik after that gets the rom of your choice, Since then I have not stopped trying roms heh, do not fear, it's okay, I encourage

Try my script: http://forum.xda-developers.com/showthread.php?t=1856553
See if the device has fastboot on it, try Volume Up+Search+Power or Volume up+Camera+Power (Let go of power when powered up and let go of other buttons when in black screen or if it says 'Fastboot Mode').
You need to install the drivers, look on google.
If there is no fastboot then your only luck is Hyper Terminal and KDZ Updater. (KDZ Updater for flashing and Hyper Terminal for wiping (That is why the device will not boot))
And of course you need to be in download mode (VolDown+Power)

Hyperterminal?? Still having no luck with kdz, I can flash stuff on the phone but it makes little or no difference as it still ends up on the android splash screen.

Yes Hyperterminal, you have to use it to wipe the data has KDZ does not help with it.
Sent from my Sony Tablet S using xda premium

Right so use hyperterminal yo wipe the data then go ahead with the rest of it. I will try this method and see what happens, the only other thing is that I can't get into fast boot mode at all, I have tried lots of times and nothing happens, can I safely do this in download mode?

[Q] Unable to unroot

Hey guys, im unable to unroot. even before the uptest.exe have reached 100% my phone has already booted up. when i enter download mode again, it says it is still rooted. anyone knows how to solve this?

only way to get rid of rootes status in download mode is to flash the stock rom via the way to return to stock lgg2. Its a thread somewhere on this forum.
even then sometimes it survives that flash. Then factory reset and try again. also try the lg software from lg with the repair recovery option

That is what he did. Uptest.exe is the flash tools used in that method.

Man, it IS unrooted, it just says it isn't in DL mode, try doing a factory wipe, Then flash the stock KDZ again, that should hopefully put it back to unrooted :good:
Also, the phone reboots at about 70% in the up test exe, if you look at the device it is at 100% while the flash tool is only at around 70%, don't worry that is normal.

yeah instead of that use the official lg flash tool. or try again, as sometimes with flashing it is maintained.

Uptest is LG's official tool, when you run uptest.exe it opens up the LG Mobile support tool, which flashes the KDZ to your device.
EDIT: sorry, i know what you mean now. I didn't know you could revert to stock with JUST the lg support tool from LG's site, i thought you had to have the uptest program :good:

when I download, install and run that tool I dont run uptest.exe, but the tool itself.
strange but ok. Learned something new.

now it's the original recovery, not twrp.it seems like ……i did wipe my internal data………………i forgot to backup…………what can do do

So your phone will boot but turns off.
You need to root install custom recovery and you could reflash one of the stock rooted roms.
You also could try to lg flasher and flash stock but must get into download mode.

D802 stuck in recovery in a weird way

Hi guys, I made a mess today. I decided to restore my stock LG software backup and everything went well. Then there were some LG updates and when they downloaded, I chose to install them. That took me to TWRP. I figured it needs the stock recovery to install the updates so I gave up on the updates and tried to reboot my device. It booted back to TWRP. I found it a bit weird, but I didn't care since I had a backup on the phone. I wiped data, cache, system and dalvik and restored the backup. Guess what, the phone would still only boot into recovery. I started freaking out so I wiped everything except internal again and flashed an AOSP based rom along with the gapps. Still wouldn't boot except recovery. Then I started to freak out even more and decided to wipe EVERYTHING, along with Internal storage. And here I am now, wiped every single thing on the device, stuck in recovery and can't connect my phone to the PC with usb. just a few minutes before I have to leave home. Any ideas on how to fix this? It was just some pointless LG update and it caused such a mess... ADB sideload won't work for me, I'm gonna attempt to find some drivers or something.

Anybody?

Dude, I've done my research and tried to fix it myself. The phone won't go into download mode and it won't connect to my PC. Drivers installed, LG tool installed. I just don't know what to do and I need help from someone who does know.

If you have twrp 2.6.3.4 you sideload rom but this may not help you.
You are going to have to go back to 100%stock.

In TWRP you have USB-OTG. If you have this cable you can install ROM from USB-flash)

I had the same issue. Only way to fix it was with the LG flashing tool. Make sure the usb port you are using on your computer is working and the cable isn't broken. I just followed the steps from this thread and it worked 100% for me.

LG G2 (D802) bricked (bootloop, no recovery) only boot loader

I've flashed a new ROM on my LG G2 (D802) 16 GB and now I'm in big trouble but maybe there's some help in the XDA-Forum?
Here are the facts:
- G2 starts and takes few seconds and then restarts
- Got no CWM Recovery etc.
- Installed the orig D80210A Firmware via Flash Tool
- Can flash anything via LG Mobile Flash Tool
- Can boot into download mode
- CAN NOT ACTIVATE DEVELOPER MODE (nothing happens while ticking on the Build-Number)
- Got NO IMEI (got a EFS Backup via ioroot but without developer Mode I cannot communicate with the G2 via USB-Debugging)
- Facory Reset doesn't change anything
- No network and no GSM (I think cause of the missing IMEI)
Can anybody help?

You need to first download the kdz and lg flash utility with drivers.
Install drivers
The factory reset deleting system, cache, internal sd.
Then shutdown your g2.
Start to downloaded mode connecting your g2
Flash kdz & voila... Done
I too bricked my phone before. My flashing stuck at 49%. Recovered using above method, all is well now
This works 1000%. I bet on it. Just remember to wipe the phone completely before flashing. You will return to stock with unrooted status in download mode. U will have your warranty back too

I've done this 10 times this morning. But I flashed the new kdz file and made the factory reset after flashing. Maybe it will work the other way? Gonna try it tomorrow but don't think this will change anything.
I've got the 49 % thing a few weeks before and the only thing needed was to change the COM Port to 41.
kind regards
