Bootloop even inside bootloader - Nexus 5 Q&A, Help & Troubleshooting

Guys I really need your help, my nexus is boolooping even if i enter the booloader screen, I cant get to the recovery before it reboots, nor flash it with fastboot....
What should I go?
Thank you so much for your help,
Rob
PS another weird thing, it only does that when connected to the usb cable, when it's not, it's as good as dead...

Sounds like you may have a problem with the power button which is causing the bootloop.

I'm afraid that you are right...I guess there is no way out than to bring it to a LG point and beg for their mercy, right?

If it's not under warranty, you could have a local repair shop replace the button. If you're good at soldering, you could do the replacement yourself.
Before repairing the button, you could try this: remove the motherboard from the phone, clean around the power button using pure alcohol, quickly press and release the button several times in a row using more pressure than normal, put it back in the phone, and try to boot it. I did this on a couple of Nexus 5 phones and they continued to work for months before they were sold.

[PROBLEM]Very bricked. Geeks needed.

Hi!
Today I got from my friend a bricked Desire S.
He said, he tried updating a pile of apps at once and it froze. He left it to cope with that and when he was back it was turned off.
When turned on it would stuck on htc logo. He read somewhere that he has to perform a "factory reset". I'm not sure what exactly has he done later (he did this with holding the volume up and power buttons and than there had to be, as he said, an option to reset the device), but the result is, that the device doesn't respond at all.
Nothing happens when connected to USB or charger.
Is there anything I can do about it?
Maybe force push bootloader with adb?
Please, help guys
Hi,
it doesn't do anything at all?
Power button?
Power button + Volume down?
Recharge battery?
Connect to a PC with properly installed htc drivers?
Remove battery and put it back?
Unfortunately yes.
Tried different combinations several times - once or twice the led blinked for like a half a second, but than nothing.
I have some flashing experience and I learn quickly. If You have ANY ideas, I'll try to make them happen.
I will try everything, as I have nothing to loose
Regards.

Whenever we see “And I was updating apps and it froze up.....” we have a suspicion we perhaps have another case of the eMMC chip packing in. At least he didn’t do a battery pull. Holding UP + DOWN + POWER has a similar effect to hitting reset on a PC. You can’t get to recovery this way.
With the phone off, hold just the DOWN + POWER. Does the phone then boot into HBOOT? (white screen with coloured text and little green androids at the bottom). If it does, great. You can choose RECOVERY from this and do a factory reset. If the phone does a series of (seven?) quick vibrations maybe not so good.
Search for “eMMC” in this forum to get plenty of people who had this problem, and how (some of them) have been able to fix it. Knowing what to search for is half the battle!
For example check this thread out...

Geek out!
Thanks for the reply,
I actually have tried entering the hboot few times - with no success.
It doesn't respond at all.
I've read about this chip, but I want to make sure there is no option to force the phone to enter recovery. Than I would probably know what to do next.

Not sounding good I'm afraid. The last resort would be to contact HTC and try to get it repaired on warranty. They are very very aware of the problem, and once you tell them "I was updating all apps at once and it froze" they'll accept it as a known hardware failure. Like you say, you have nothing to loose in trying.
A friend recently had this, and sent if off to HTC for repair. As the description of the fault was a known hardware failure, they never bothered to test it first, so they didn't notice it had been rooted! It just went straight through to get a main board replacement. It took five weeks for them to return it though. Best fish out that battered Nokia in your drawer and charge it up ready!
Good luck!
Uh, these are quite bad news, but I'm pretty sure they will accept it on warranty, since my friend haven't done anything "illegal" with it
Thank You for Your fast replies
Regards.

Sorry dude if it doesn't connect via usb you've pretty much got a paper weight.
My moms basement.
Look up jtag. It's your only option at this point. Unless the phone was purchased under a year ago. So yeah, paperweight for now.
thanks for the help i figured the skyrocket would say sky rocket on it lol so i just jumped into the s2 i777 forum like a noob i feel so dumb but will the jtag thing for sure fix it
Almost nothings for sure but it's a pretty good chance they revive it. mobiletechvideos is who a lot of people have used.
ok what about the usb jig thing has anyone tried that an how much does the jtag fix usaully cost

yes i am for sure its hard bricked im so mad at my self i could rip my head off lol but i guess thats what i get for rushing into it im guessing everone would reccomend the mobiletechvideos fix for 50 instead of the 30 dollar ones on ebay or does it matter?
Spend the extra 20 bucks. lol It might matter or it might not. You don't wanna be the one that finds out it mattered though. lol
I would trust mobile techvideos over anyone on ebay. They have a stellar rep.

Hey there, Today my phone got stuck in a bootloop where the screen was black and there was an intermittent vibration. I couldn't get out of this bootloop at all. I tried getting into recovery mode, download mode, using Odin, holding down power for more than 20 seconds, removing the battery for 10 minutes, etc. Anyway, I figured, there has to be a solution without having to take apart my phone and trying to use JTAG, Geez! ANyway, I decided to try pressing the power and volume buttons in different combinations with and without the battery, and while being connected or disconnected to the PC. OK to make a long story short, here is the combination.
Plug USB into computer ( I used win7) without connecting it to your skyrocket.
Remove the battery from your phone.
Insert the Data cable into your phone without the battery.
Install battery and quickly press both the volume up/down button and the power button repeatedly (about 5-10 times) Basically press and release both sides at the same time over and over again until your skyrocket pops out of a bootloop. It took me only 5 presses.
I'm not saying this will work for everyone, but it worked for me. Due to the fact that this happened on a whim, I can't test it out to make sure the steps are just right. Whoever tries this, take note of the steps.
I hope this helps you guys out. Cheers.

what you have sir is a stuck power button, by repeadetly pressing the power button you momentarily "unstuck" the button, it can stay unstuck like that or it can become "sticky" once again, more info on that in the 1stop sticky

uhhhh, another person who is slightly misinformed. a boot loop doesn't equal JTAG. if your phone turns on AT ALL u should be able to recover it and get it working. JTAG is required for a brick, and like its name implies, a brick is just that. A phone that does absolutely nothing but sit there. No display, no sound, no vibrate, nuthin

I would like to know if i am able to achieve download mode, what do i need to do, what files and how to install to return this phone to stock?? please help!!!
Take out the battery for a few seconds and put it back; then while holding Volume UP (+) press the Power Button.
See what happens...

Nothing. Happens it don't light up or power on at all. It is not reconized on computer either. It's hard bricked.
Make sure the Battery is charging...
How can I make sure the battery is charging when no lights come on at all? All I do know is I had it plugged in for a while yesterday and it got really warm. But no lights whatsoever. The screen doesn't light up at all neither does the led.
??????
There are no notification lights on the D720, but when you plug it in with a charger, you should see a battery bar on the display.
Other than that, you are probably right about hard-brick.
I, luckily, never had a "brick" on the Nexus S, so someone else with experience may wanna chime in. But Google and YouTube are your friends.

Please help me, i have the same problem
been awhile since any action here. saved mine with JIG method once but this time it won't work ??!(why) , in search of a solution again! -> hardbrick #2 on this device!
You guys can try a USB Jig. If that does not help, I think JTAG is what you need.
Jesus... just to revive this thread (and this concept of hard bricking), I think I just accidentally bricked mine as well.
Here's exactly what I did:
One moment, it was working spectacularly - fully stock, but unlocked. I had just listed it on eBay, too.
So I ran a factory reset on it (from the Settings menu), also "erase USB storage".
Then, after it shut down for the reboot, I pulled the battery.
...
That was it. Now it doesn't turn on for anything whatsoever. No device detected on USB when plugged into PC. Remove, replace battery, hold VolUp+Power, nothing. Plug into power adapter, nothing. Nothing at all.
But the back does get lukewarm after a minute or so, as if it's alive in the head but frozen, unable to start the bootloader.
WTF? I also have 2 more of these Nexus S 4G's, and both of them seem to have Flash storage chips that exhibit the same behavior when their chips are placed in (this) working motherboard. They can't boot. When I try to "hot-flash" it by booting the bootloader then swapping the Flash chips, they can't flash anything (this is probably to be expected). So, if I can get my ONCE-WORKING phone back to life, there's a good chance I can get another working as well (one just has a cracked glass, otherwise working mainboard & peripherals).
It's old, yes, but it's a damn shame to E-waste these things for a stupid software problem like this!

Bootlooping contantly - Think i have a bad eMMC

My wife's Nexus 5 seems to have self-destructed...
I will randomly reboot, even in recovery & bootloader. then just cycle for a while, constantly showing the google screen, then black, then google again. Sometimes it'll boot, but then reboot within a few minutes and it all starts again.
The device is just out of warranty.
This started randomly, not after flashing a rom or anything. at first, it seemed like a rom issue, it was only rebooting every few hours, and hadn't in recovery or bootloader. So i rebooted in recovery and reflashed the same rom (Mahdi kitkat final). As soon as it finished flashing, it rebooted on it's own. The issue has gotten much worse now. It won't stay in fastboot for more than 1 second, and it won't boot into recovery (both via holding down buttons).
I think the phone's probably dead, and I've ordered a oneplus one for me (wife will get my hand-me-down nexus 5. Domino effect!). Does anyone have any ideas? or think they can fix it? i'll send it to you.
Thanks for reading!
It's a bad power button. Almost guaranteed. It would not be software if it happens in all modes.
Not too expensive to get fixed really.
Dead eMMC: fastboot oem lock, rebooting then it goes back to being unlocked
Broken power button: reboots without touching power button, even in bootloader
Really?!? WOW!
That kind of makes sense...
is it the physical button you push, or the clicker in the phone?
A quick google search didn't find any replacement power buttons. Any Ideas?
Thanks for the insight!

My nexus 5 had the power button issue which caused it to reboot randomly and also caused wifi to stuck at "turning on wifi". Was going to use my credit card extended warranty to cover the cost since it was out of warranty, but LG fixed it pro bono. called google nexus hotline and they will get LG online for you. Good luck.
I got a bad emmc, is there a script available for the nexus 5 to reparation it. Its already dead so i don't mind testing anything.

Damaged eMMC is a lost cause.

Boot loop after rooting MMB29V. Please help.

I was running the latest stock image (MMB29V) since yesterday on my Nexus 5 and today I used the Nexus root toolkit as always to root the device. Well TWRP flashed once and it said it copied the root files to the device. I had it in my pocket for a few minutes and after that it went into a crazy constant boot loop. It will stop eventually but if I keep the charging cable in it won't stop. I cannot get into recovery because I get the "Start" screen but I cannot advance because it reboots too quickly. I have found a few you tube videos where people push the power button like they are playing the old school game "Track and Field" but this does not work for me nor do I think it's a power button issue. I think I stupidly might have hit some kind of button combo while I'm my pocket believe it or not. I pulled the cover off and was hoping to pull the battery but Im not a fan of doing that since its not a simple task. Any help appreciated. This phone is dead to me and that is NOT good. I need to get this working.
TIA
Bill

It quickly restarts. I want to say its not a problem with the power button because it has been fine for a few years now w/out issue and only happened after rooting earlier today. Right now the only way I can even get the phone to turn on is the plug the charging cable in and then the restarting commences. Does it sound like a power button issue? Possibly but its hard to believe, I dunno. Waiting on a call back from Google tech support to see if they are any help.
It could be a power button issue. You'll have to remove the motherboard to find out.
Once removed from the housing, quickly press and release the power button several times in a row using more pressure than normal. While the motherboard is out of the phone, clean around the power button with pure alcohol.

Did NOT want to screw up my phone so I sent it to LG. Took a few weeks but it cost me 78.00 total for them to repair the power button issue. Whatever they replaced also fixed the low volume issue I was experiencing as well so it worked out.
