Edit: I was misusing the term boot loop. Stuck at LG screen / CM boot animation.
Last night I rooted my phone, installed clockworkmodrecovery, and made a backup. I installed CM7 and all was more or less fine at this point from an OS point of view.
The SD card wouldn't mount, the brightness and volume were both way too low even at max, and there were other minor annoyances, so I decided to put things back the way they were while I did some more research and restored the backup I made.
This was apparently a bad idea. It's stuck at the LG logo permanently.
I can still access CWM recovery and have tried wiping everything it lets me wipe, restoring to factory, redoing the restore, reinstalling CM after a restore, and various combinations thereof.
With CM installed the boot animation keeps looping so I assume that's boot looping. I also assume the constant LG logo is a boot loop.
The screen never turns off though. Is it still a bootloop or am I misunderstanding anything? Any suggestions on what I can try?
Thanks.
Bootloop is when the phone won't start completely; it shuts off after a second or two. Stuck at LG should theoretically be cured by factory reset. Try doing that in cwm.
Or, long press power to shut down phone. Then hold volume down and power for several seconds. You should get a black screen with white text. Press power twice to confirm.

Factory reset through CWM still leaves me stuck at LG after restarting.
I assume the second part of your message was how to accomplish the same thing if CWM weren't installed, but Power+VolDn brings me to CWM.
Would the following link be a good start to try fixing it?

Looks like it to me, but figured I'd run it past somebody else before I just start making things worse.
I'm not totally sure how/if the two are different. The second option is 'factory hard reset.' Try holding vol down and then also press and hold power. It might take a few trys to get it right.
Xbsall's unbrick guide is for if you have a really bad brick from installing a wrong rom, etc. It does not sound like you have that. If the factory hard reset does not work, personally I would instead flash one of xbsall's rooted ICS files:
http://forum.xda-developers.com/showthread.php?p=39269819
But that is just my take.
I'll assume you know what you're talking about and I'm just not getting it, but Power+VolDn is how I've been accessing CWM this whole time. If there's an alternate timing of pressing those buttons to get back to the other factory restore method, I'm not seeing how. CWM wipe / factory restore remains ineffective.
I've got the files from your last post downloading and I'll try the ICS route in a bit.
Thanks for your help so far.
Phone is up and running. Thanks a bunch, your tutorial was rather well done.
I wasn't able to use v1.1 of the flash tool as it wouldn't launch, but 1.2 worked just as well.
Super! You seem to be someone that can read and follow instructions
On my phone (xbsall's ICS) I access recovery by pressing volume down when keys flash during boot. FYI If you want to change from twrp to cwm, you can install cwm from the included 'P940 recovery' app included in the .bin.

@Wulf2k Hey, question... I have not set up a permanent Dev-Host account, so I am wondering:
Are the links for 'bag of goodies' and the P920 .dll still good?
I think they go dead if noone downloads for 30 days or something like that.
Every link was still active for me, I didn't have to find alternate download links for anything.
TWRP wasn't something I'd ever used before, but it seemed good enough for my purposes. Think I'll stick with it.
I haven't really looked into online storage of large files for a while, but have you considered Dropbox? I've used it for small stuff in the past and I don't think it disappears after a month.

I was curious if anybody could help me. I have a g2x from Wind (p-999dw). I am pretty new to rooting and such but wanted to update my phone. I got it rooted successfully and then tried installing the CM7 Rom update. Backed up with cwm first and then continued. Now my phone is pretty f'd. Every time i try to turn it on it just hangs on the LG screen. I tried the flash recovery method with nv flash and was able to get a cwm recovery menu up but when i try loading the previous working setup, it says successful, i restart the phone and now i get the LG logo with the blue status bar below (which wasn't there before I used the flashing tool) it which moves for a few seconds, then freezes. I've tried every option in the menu and i still cant get past the LG logo screen. Can anybody help me? I've spent hours trying and can't seem find a way to fix it. Don't care if i lose all my data and apps just want my phone to work. Any help would be much appreciated. Thanks.
I believe you need to remove the battery then try to boot into recovery (hold volume down and power)
Sent from my G2X
Need to pull battery let sit for a couple seconds reinsert battery. Hold volume rocker down and power until you see the second LG screen should have some blue and purple surrounding the LG logo. After that select wipe data factory reset, then go to mounts and storage and select wipe cache/data/system. If you want do each one twice. Then you can go through the process to flash cm7, don't forget to flash gapps (google apps) as well. If you don't flash those you won't be able to sync your phone with Google and retrieve your contacts and such... hope this helps.

If none of the above works, rom for recovery will definetly fix your problem. Check the development thread it's in there.

Hi,
I will prefix this (as there are a few people around with this problem who can get into recovery mode) with the fact that holding down Vol- on boot is not getting me to the recovery / bootloader screen.
I have a rooted HTC Desire S (rooted it nearly a year ago, so info about the hboot etc is a distant memory).
Anyhoo, I decided to have a play about with one of the ICS roms but it was a bit buggy and the camera drivers still aren't working for video so I decided to go back to Endymion V3.4 - http://forum.xda-developers.com/showthread.php?t=1310845
I did a full wipe, installed base rom, installed optional addons and then upgraded to 3.4 - booted fine into the OS so set about getting my system set up the way I like it.
I noticed that endy came with a theme installer so clicked on one of them to have a look, it asked for root, said it was installed and would need to reboot to take effect...
SO
the problem is, it now won't boot and is stuck on the white HTC boot screen.
Holding vol+/- and power buttons reset it but it just ends up back hanging on the boot screen.
Have tried pulling battery and trying again.
Holding Volume Down when powering up is no longer doing anything
So, I either need a saviour to point me in the direction of a fix.. or a kindly sould to break it to me gently when they tell me my phone has gone to the USB Dock in the sky..
Any help will be greatly appreciated.
Thanks
update:
After pulling battery again, pulling out sim and sd cards, booting with vol- held down, i got into recovery. Am going to try and flash a different rom after doing a full wipe, I'll update once it's done but any insights in the meanwhile will still be appreciated
Sorted, cleared the thing out, stuck reaper CM rom on it, rebooted and everything is peachy for now.
Thanks me
Curious if anyone knows why this might have happened?
because you didnt flash the addon zip which was released alongside endymon and then tried to use the addons,it does say on the screen do not use these unless you have installed the addons
I pulled my vortex out of storage the other day to tinker. It was rooted but fully updated stock 2.2.2
When I booted it up, it stayed on the boot animation 20+ minutes, until the battery ran out. I've tried booting it up again but it keeps bootlooping.
I figured I'd just flash a new ROM onto it, but I never put a custom recovery onto it and the only Vortex Recovery I found was this;
http://androidforums.com/getitnowmarketing/330813-all-one-recovery-thread.html
However, it says I need to do on-device commands and stuff to get it working, which obviously isn't an option.
Is there any other way you guys could think to resurrect my old Vortex? My Droid Charge is my phone now, this thing doesn't get much use anymore, but I'd still like to get it back in a usable form.
EDIT: FYI, already tried everything relevant in this thread: http://forum.xda-developers.com/showthread.php?t=1031596
If you flashed stock rom. Try hard reset.
Home+vol down / vol up+ power.
thank you! that button trick did the job!
EDIT:
well, it worked once, but the phone had been uncharged for a while so the battery died, and now i can't get the trick to work again >_<
is there a way to re-flash stock without a custom recovery?
Hi there everyone, recently signed up on here as xda seems to be the holy grail when it comes to all thing smartphone.
I'm fairly new to these type of phones and recently was given an infuse 4g that was suffering a power button problem.
The power button problem has been resolved with a new one and the phone was working fine for 3 / 4 weeks.
One day the phone shut down by itself and entered the boot loop syndrome. Factory clearing it hasnt seemed to do anything to resolve the problem as it continued to reboot continuosly.
I came across the thread about gtg ultimate unbrick guide in the developers forum and this seemed like a good way to go, get the phone all the way back to stock and then work from there.
Kies installed and all drivers installed fine. downloaded the gtg unbrick pack and followed the instructions line for line. Odin reports everything passed, took about 2:59 to complete.
phone rebooted and continued to do boot loop so went into recovery as stated and wiped data and cache and rebooted again.
phone is still stuck in some sort of boot loop, but it gets to display the 1st of the setup android phone screens, then just as you get a chance to select next to go onto the next screen, the phone reboots.
Any one have any idea what could be going wrong or as im fairly new to this, is there anything im doing or not doing right that is causing this.
The phone is an at&t infuse.
regards
Trevor
sound like an issue with stuck power button. it's a know issue with this model. google "infuse 4g boot loop" there's few youtube videos you can try.

Click to expand...
Click to collapse
I've already replaced the power button with a new one, but the technician i use did say he will remove the power button completely to see if it does the same, just to rule that out

just redone the gtg flash and it boots into the os (ver2.2.1) and then within about 5 seconds turns off and reboots
can the new on off switch be faulty......im not so sure as in recovery mode, i can leave it on that screen forever and it doesnt attempt to reboot
Tried the one click repair with hemdial or what its called, updating thisnpost via a moto defy mini so excuse any typos.. The hemdiaOl just seemed to meas it up further. So got baxk into downliad mode with odin and reflashed to gtg brick recovery. Not fixed, still booting but at least the screen is now viewable.
To recover one of these phones, is there like a definitive guide as to what to do to first prepare one of these phones for recovery, ie, first, flash to this with cwm and then clear data, cache, dalcik etc. like an idiots fuide, i feel i may need one

Hi guys,
New to flashing custom ROMS. Good news - flashed CM12, then LiquidSmooth and I'm learning a lot after having soft bricked my phone a few times. Bad news - After trying to get back to Stock I'm not able to get out of this LG Logo bootloop. The LG logo will flash, screen will go black and the whole process starts again. It doesn’t progress past that. I'm unable to get to TWRP recovery or download mode.
My idiotic move:
Iffy stability with camera and mobile data with CM and LiquidSmooth. Decided to go back to Stock.
I flashed my nandroid backup, which I believe led to a bootloop (can’t remember). Was able to boot to TWRP and get back to CM12. Then I had the genius idea of using AutoREC and selecting the “Go Back to Stock” option. Yes, it’s already sounding like a bad, and nonsensical idea as I say it now. Can't remember exactly what I did next - I either flashed my nandroid backup or did a factory reset through CM settings. Threw me into this bootloop.
The details:
Model - D800 - Am sure of this.
Stock software before flashing CM12 was Lollipop 5.0.2 via OTA.
TWRP Recovery 2.8x something or other. Used AutoRec to flash.
I can interrupt the bootloop and access Factory Hard Reset through Power + Volume Down
Had to go to JB Bootloader in order to Flash ROMs. Errors returned otherwise.
Roadblocks:
No download mode. Holding Volume Up & Inserting USB cable doesn't work. Although am able to get bootloop to include a blank screen with red flashing LED through this method from time to time.
Phone boots up, and goes directly into bootloop when plugging USB cable into phone. This happens both when plugging into a wall charger or into a computer. I think this is probably the biggest pain and is holding up things from progressing. Can turn off phone by holding down power for a few seconds, BUT if the phone is plugged in it will continue to boot on its own.
Phone not recognized by computer & ADB However, was at times able to get Device Manager to recognize the phone as an "Unknown Device" after going to the Factory Hard Reset screen. This is no longer working after trying different drivers. I’ve went through LG Mobile Universal Driver as well as the Koush driver.
Going through Factory Hard Reset via hardware buttons only throws phone back into BootLoop
Can’t boot into TWRP
Any insight or help guys? Thanks in advance. I think getting into Download Mode will be a quiet victory. I’d like to try to use Supersports guide once I get there to go back to stock.
