I've been able to flash custom ROMs onto my HD2 without problems for a long time.
However since recently when I flash a ROM (e.g. radio) it goes into a constant reboot mode:
- Does not turn on without power cable anymore
- When I plug in power, it vibrates and the white screen comes up
- After a few seconds it goes black then comes the white screen again
- Goes on forever...
I was able to get the it to run again by first doing Task29, then installing the latest original ROM (1.66.405.2). However, as soon as I install another ROM (e.g. RADIO_2.07.50.27_2) I get into the endless reboot again.
Update: After another try to get a different ROM onto the device, I'm not even able to flash anything working (endless reboot).
Please help!
bent battery pins.
Thanks a lot that actually seemed to be it.
I noticed a pin was bent when I finished my flashing crusade but I didn't connect it to the issues I noticed.
i have the same problem today, but no bent pin. I cant even charge it, when plug into charger it charges for 5 seconds then boots up to HTC logo white screen without any info for 10 sec then reboots itself forever, I cant even charge it at the moment because once it boots up it goes to HTC logo screen and reboots the whole time rendenring the battery unchargeable. I assume the battery is faulty eventhough the phone is brand new.
any ideas?

try this, it might work .
Remove battery for 10 minutes, plug in charger and wait 5 minutes, hold power for 10 seconds then release, insert battery normally, should charge fine now

I was bought a LGOG ATT model from US, it was working with full battery but suddenly in on condition, it goes blank and not able to on again.
when i insert power cable/charger cable it shows only stable red light (it is not flashing).
also i open the phone and removed the battery and then plug it with charger but still it shows stable red light (without battery).
as i m not able to switch on so not able to go in download mode or any thing else.
is it perm bricked???

I would do the battery remove again, leave it disconnected for at least 10 minutes. With no battery and no charger connected, press the power button for 10 seconds, then let it rest.
Make absolutely sure that you did not damage the connector for the battery to the motherboard. With no power cord, reconnect battery and try to boot. If a 10 minute battery pull doesn't work, it may indeed be bricked.
The phone can act very strange and then go completely normal forever also, some people have left it plugged in for hours with the red light and it magically began to work again. Best of luck.

I haven't used LGNPST but I understand that it does get stuck at 85%, from what I have read.
A lot of others on this forum have experience with flashing, try searching or asking someone. Glad your phone powers on again.
Same Problem
I know this thread is quite old but I didn't want to bother anyone by posting another thread about the exact same problem. Anyways, my phone is behaving in the exact same way as the OP's and I have tried the aforementioned fix to no avail. I know this is a bit of a toss up but does anybody have any other ideas?
New issue ..
Today i didn't have a charger with me so phone drained completely. Now it no matter how long i charge it it will not boot right.
This is what it is doing, two kind of behaviors:
1, when it is plugged into an outlet screen remain slightly lit, able to boot into bootloader, able to boot into recovery (once phone turned off itself in recovery..). when trying to boot into android phone hangs on LG loading screen and LG loading screen disappear as soon as unplug the phone from the outlet . LED light remain off while plugged in, it should be lit when being charged.
2, when it is plugged into a computer phone seems to boot itself, LG logo flashing on and off quickly seeming like bootloop.
I have flashed the rom again it didnt help.
Edit 1: fixed by factory restore

CWM supports charging your battery, so use the strongest charger you have (spec is 2amp charger) and leave it there for a few hours. the reason it flips on usb connection is because most usb is only 0.5 amp or maybe 1amp if you're lucky.
You should be ok gotta be patient though.
fixed

Yea you just have to leave the charger in for a while..mine did this...but you can also try this
Unplug the charger hold down the power button of 15sec and then put the charger back in (the red light should come on)
Then the screen will show the LG logo about two times and then the battery charging logo
And just give it a minute or two and power it up
The LG charger is 1.2a
Sent from my LG Optimus G using XDA Premium 4 mobile app
Here's the story: I'll try to make it as short as possible (I'll also put on a TL;DR at the end)
My phone is rooted, flashed to Cyanogenmod 11 nightly build, no problems when I flashed these guys.
I installed Lucky Patcher to patch an app, put some files on my SD card (bunch of PSX games)
just put it out there if that changed anything
My battery was low at that time and I did not expect that if I let it shut down by itself, I could still open it just like I do in the past.
Phone totally has no charge on my battery 0%. I plugged in my charger, the phone opens up but it only opens the M logo with Dual core technology (not the pulsing M). Tried to charge it overnight, still stuck on dual core screen, tried resetting using Power + Volume Down, and also going through where AP fastboot, BP Tools was, If I choose any of them (except for fastboot) it would redirect me again to the dual core logo.
sometimes I get lucky if I choose BP tools and goes to TWRP recovery (safestrap installed), tried to boot there and still no luck.
also tried unplugging charger while on the selection of AP fastboot and just shutdowns my phone. also one time it redirects me to one with a battery icon and a question mark.
I also don't have access to factory cable, can't buy one because it's not available in here in the Philippines, tried making one but I reaally suck at soldering, also when I opened up the wires, it only shows up 3 wires, red, green, and white, the other one I opened was only red and black.
TL;DR : Phone battery is dead, when plugged in charger, Motorola Razr Stuck on M logo (with Dual core technology). I also don't have access to factory cable, can't buy one because it's not available in here in the Philippines. Also there's no more Motorola stores that I can get a fix (I think they got bankrupt :silly
I really love this phone and I would really appreciate if I could get a quick fix
Sad, it seems that the questions here seldomly get answered, hope the experts go online soon

It's OK don't worry. Just charge the phone for about two hours, unplug the carger and faster reset the phone wiht power + volume up + volume down. This way you can boot to safestrap. You will see that battery is on 0%, so plug the phone in the charger and wait. Until you are in safestrap the phone will charge. The battery needs at least 5% to boot the OS, I myself prefer to reach 20 even 30 percent. Then on safestrap's homescreen press reboot, then system and after the phone reboots wait or press search when safestrap's splash screen shows and the OS will load.

It Worked! Thank you so much for your help. The only problem I have now is that everytime I get my battery low, it doesn't go on charge mode when turned off. is there a fix in that? But overall, the trick that you thought me worked, and I'm using that trick when my battery gets low.
It seems hard to get a fix for this issue, so I used the app "Tablet Auto Power Off ★ root" and set the auto shut down when the battery reach 5%. It gives me enough power to restart the phone when I'm ready to charge it.
Im on a trip, and my battery died. When I got to the hotel, I immediately plugged in my tablet. As soon as it got to 1%, it started booting up, but because of how much battery it uses just to boot, it basically died a second or two after it booted up. Then, it repeats. As soon as it gest 1%, it starts turning on again, then when it gets to the lockscreen, it powers down. It's like a bootloop, but I can't get out of it :crying:

You try holding the pwr button for about 10 seconds or maybe longer when it's trying to boot? It might force it to just shut down.
There's a "forced Shutdown" button right by the SD card slot (it's colored yellow in my sgp561, maybe different for other sub-models). Press that button for 10+ seconds using paper clip tip or similar pointed object and it will shutdown completely.
Another possible solution is to plug the charging usb cable to a high current usb charger (4 amp+) that should be able to supply the energy demand at close to 0% battery charge.
Another option will be to boot into bootloader. Bootloader uses barely any battery. When it's not plugged in and off, press and hold power+volume down. Then plug in. You could try to do that while plugged in, but likely not to work.
Is it hardbricked? I hope it isn't. I had 5.1.1 flashed on it and then wanted to downgrade back to 4.4.4, I had backup in TWPR, so I recovered it. Everything went fine, then I restarted the phone, it vibrates on start, screen turns on but is black and in about 10 seconds it restarts without logo appearing, can't access recovery and it restarts without stopping, the only way to turn the phone off is simulated battery pull. Am I done for sure or can I somehow save it? I am panicking very hard right now. It is in warranty, but I doubt they would fix it for me.
Also - when connecting to PC, the phone doesn't show up.
The problem will be solved if the phone was left to drain to zero! (Don't charge the device untill the vibrations stop . It could take 2 or so days but worth it!!. ). (Or you can remove the back panel by unscrewing 8 screws total and disconnect and reconnect the battery flux cable which is near to the sim slot 2) then charge the device to 100% and turn it on normally.
