Got an LG 540. Was on 2.3 CM7. Used KDZ to downgrade to stock 2.1, but forgot to wipe cache, user data etc. Now phone is in bootloop and sticks on Android logo.
Only thing I can do is enter Download Mode. From there I can reflash a ROM but whatever ROM I flash it always sticks at the Android logo. Can't access recovery mode to wipe cache etc. Am now on 2.1 rom with fastboot but of course that doesn't help because it doesn't boot up.
Any way of getting my phone to work? Advice extremely appreciated.
well if you can enter fastboot mode you shoud just flash any 2.3 rom
can you get it into fastboot mode ?
if yes you can wipe it via PC.
If not you have to install 2.1 via download mode

Thanks to those who helped, I really appreciate it. I just used my phone warranty to get it fixed (restoring the old boot and recovery image file first). The downside was that I waited to months for 2 months before I can get my hands back on it... . Thank you again very much

do you have the engineering hBoot or the stock hBoot? Can you boot into a fully working ROM?
it happened to mine as well...did you flash a new kernel on it....sometimes on a rom if you flash a new kernel to lets say overclock your phone or some sort it goes into a BootLoop where the Mytouch boot screen keeps rebooting but does not go into any rom...if you can get to recovery wipe cache and try to reboot..if you cant get to recovery try getting to it through the normal Hboot (volume down +power key)..hope it helps

If you can boot completely, install ROM Manager and flash a recovery with it. If you can't boot, then you can flash a recovery using the fastboot tool from the Android SDK, but only if you have the engineering bootloader (0.85.2007)

I see only stock bot. ( turning phone on while holding vol- down rocker button)
i only see stock menu
When adb said my device was offline I just typed in (While it was connected)
Code:
adb kill-server
adb start-server
any my device was online.
Are there anyone who knows what they are talking about? Or, most people just say things to be busy or something. Come on people if you dont know how, why waste your time

Solution: http://forum.xda-developers.com/one...bootloader-locked-t3212187/page2#post63494201
================================
Hello,
This afternoon, I was preparing to flash Oxygen OS 2.1 through twrp but I wanted to make a backup first. Attempting to load up twrp by holding Vol- and Power, my OPT flashed the starting frame of the boot animation for half a second before turning off. This repeated every 5 seconds. I could still boot OOS normally at this stage.
I decided to reflash twrp so as to make the backups, but on attempting to flash it, I saw that my bootloader was locked. So into fastboot mode I went, but trying to unlock it, it did the same as trying to get into recovery. As soon as I sent the command, "fastboot oem unlock", the screen went dark, flashed the starting frame for the boot animation, and promptly when dark again.
I now can't boot up normally, nor can I enter recovery. I can access fastboot mode, but I can't seem to make any changes.
I've attempted to use this solution as well as several other similar ones with no success.
I've had my OPT since 17th of August with absolutely no signs of trouble until this afternoon.
To me, it seems like it could be a hardware issue, but I'd hope it would last more than 40 days.
Any suggestions?
Thanks.

I'm not sure what I was doing, I was going to flash different ak kernel as my wifi didn't work.
HOWEVER
I read someone suggesting if you still have bootloop after trying the qualcomm recovery tool, try booting to fastboot and use: fastboot continue
my opt booted nicely to hydrogen os and after I shut it down it no longer bootlooped and I was able to get to recovery.
I'll post this to your reddit thread too, maybe it might help somebody one day, hopefully this works for you too

Mate! that worked for me too!
However... It only seems to skip the bootloop for that power on. After power off, it returns to the boot loop. I also still can't unlock the bootloader and can't access recovery.
But at least it can boot into OS with fastboot continue!
Thank you.
Weird, after the first successful boot I rebooted and a chinese menu prompted me if I wanted to unlock the bootloader, and I did.
Maybe you should try different recovery packages.
But I'm glad to hear you at least got past the boot loop

Can't flash a new one since the bootloader won't unlock :/
I guess the phone is in working order at the moment, I just can't let it get turned off without my computer next to me...

Nono I mean different qualcomm recovery packages, the ones with MSM8994DownloadTool, I also replaced the stock recovery in the qualcomm package with twrp just in case if that matters

but it might have also been this: https://drive.google.com/file/d/0B14IjYN3PtxcSlJ5aGQxX3JERHM/view?usp=sharing
It's also worth mentioning I flashed both a few times before I tried the fastboot continue command so try both a few times and see if that helps, also I replaced the stock recovery with twrp in both recovery packages before flashing.
Edit: And best of luck, I'm rather confident your OPT is going to work properly again.
Boot Loop
I got the same problem.
Phone is rooted and i can't unlock it in cmd, just reboot itself when i try it.
The only way for me to even start the OPT is to (volume+ and power), to get to fastboot mode, then run "fastboot continue" twice in cmd.
If i reboot the phone it get cought in a boot loop where i can see the logo, reboots about every 2 sec.
Is there a solution for this? I've been searching 2 for two days now.
I don't care if i have to reset the entire phone.

I finally got my OPT working again, tried Qualcomm recovery tool, wasn't able to complete the "MSM8994DownloadTool"
So i downloaded "A2001_14_A.03_150805" in a guide from technobuzz.net/unbrick-oneplus-2/
A similar but it does a entire wipe of the phone, nothing left at all. WARNING!
But i was okey with it.
Well the phone was in Chinese when it was all done but to change language was no problem.
I finally managed to solve it on mine. I had been cautious over the past weeks to not let it run out of battery or get turned off while away from my computer as
Code:
fastboot continue
was the only way I could get past the boot loop.
My core issue to solve was that I couldn't get it recognised as the USB Diagnostic 9006 under Ports in Device Manager. I installed the driver from here manually by right clicking the /qcser/x64/qcser.inf file and selecting install from the context menu. Then, I powered off my OP2. While only holding Vol+ (not power or Vol-), I plugged in my OP2 to the computer and it was finally recognised as the 9006. Then using the recovery tool from the prior link, it installed and rebooted my OP2. The moment of truth was when it rebooted and didn't enter a boot loop!
Then with the Chinese recovery prompt, I selected the top/first option and it brought me to the welcome/first setup screen of OOS.
It wiped the internal memory, and installed OSS 2.0.2 (don't know if coincidence or not as that was my prior OS as well). Now to install twrp and update to the latest OOS hopefully without a hitch.
Happy to finally know it wasn't a hardware issue like a failed eeprom or a dud nand controller as my prior phone (Samsung Note 10.1) died to a failed nand controller as well.
Will update with news of twrp and OOS, but I feel that should go smoothly now. Thanks to the others that helped in this thread too!
Yeap, all good!
Flashed official twrp through fastboot and batch installed OOS2 through 2.1.1 patches and SuperSU. Everything working like new!
Phew.

I am using stock recovery,unrooted phone,OOS 3.0.2
Well this is my first post here.I flashed cm 14.1 on my devices with gapps through twrp.I managed to get to recovery with the adb drivers (as I mentioned I have a broken button so pressing Volume Down+Power+Home won't work).Everything was ok but due to the critical bugs of this rom (was still in development) I decided to downgrade to cm 13 which had less bugs.So I tried getting into recovery but everytime I gave the command in it would reboot to the system (not even in stock recovery).So I decided to flash the stock rom with odin and then try entering recovery mode.After flashing I actually realised that I f*cked up cuz I couldn't wipe the system data/davik cache,due to the fact that my home button is broken and so i cant access my stock recovery.Now my device is in bootloop...I already have a usb jig and it will just make it boot into download mode where i cant really do much.Any help would be appreciated.

Then you'll need to fix home button, it's not part of screen. It's got its own circuit underneath
I do not have a great track record when flashing ROMS etc on LG devices..
Today I decided to flash my device back to total stock in prep for the incoming Oreo update and also the dreadful battery life i've been experiencing.
I tried using LGUP first but found that once the device completed it's boot, it got to the 'Android is starting' screen before rebooting.. It did this a few times before I turned it off and booted it into download mode.
I then used LG bridge and flashed everything directly through the Bridge software - This was successful however when it boots it is now doing the same thing.
It will show the boot animation, flash very quick the 'Android is updating/booting/upgrading' white screen before rebooting, showing 'erasing' very quickly then showing the boot animation again.
What am I missing here? Why is this happening?
For some reason flashing stock bricks the phone just factory reset it though the recovery. Tell me did you succeed...

So yes, I managed to resolve this somehow.
As I managed to get into fastboot mode, reflashed TWRP and formatted the data partition - reflashing via bridge tool causes the same issue again and I only managed to get eh device to boot after I accidentally booting into safemode and allowing the device to finish optimising. Rebooting into normal mode then worked just fine.
