I have been running Zeus Rom for months now and everything has been fine. Until today. I was just on my phone today and it cut off. Then it went into a boot loop. Won't go past the Samsung screen. I can't find any solution to get the phone into download mode. I have read everything. Switched computers, tried different ports and even switched usb cords. Even tried several combinations of buttons to no avail.
Here is what happens when I try to get into download mode:
I hold down up and down volume, insert battery and then plug in usb cord. I see a spinning wheel and empty battery sign. Then it cuts right back off and does it all over again. Could this be a battery issue or what?
My phone has been bricked before I fixed it with no problems. This has got me stumped. Something is preventing me from getting into download mode and keeping me in boot loop.

To get to download mode, be sure to plug in USB before putting the battery in, and keep holding down the volume buttons down for some time.
If the battery isn't showing a charge, though, then let it charge. If it isn't charging, try another cable, and then maybe a new battery.

Tried another battery I had, not fully charged, and the first time I put it in the bottom buttons lit up and the phone booted up, only to cut back off and do the same thing again with the boot loops. It too showed this battery to be completley dead. I am not sure if that is so or not as I have't used this battery in a while.
I am charging both batteries now to try to get them charged. I have one in a wall charger and hte other in the phone plugged into the wall. The one in the phone is still showing no charge as the phone keeps cutting on and off and showing the battery sign witha spinning circle.
I have no idea whats going on but need to find out soon!

You dont have to plug it in before puting the battery in...i never do...
How i get in download
1) pull battery
2) put battery back in
3) hold volume up + down simutaniously
4) while holding volume plug usb cord into phone
it sounds like he is pretty much doing it the way i do except for the volume he does before putting in battery...should work either way
Could it be a problem with your motherboard/mainboard whatever you wanna call it? When did you get the phone? If its been under a year i would file warranty with samsung...not att. If it is the mother board they probably will never even know its rooted or anything since it wont even turn on...and no software will fix it...
There still is a chance they will find out its rooted and has a custom rom on it...but i think the chances of that are highly unlikely...so i would go for warranty...

UPDATE:
This is so weird. After nothing working all day, I finally remembered something. About 15 mins before my phone started this today, I dropped my phone while getting out of my truck. I didn't think anything about because I have a double layer case on it. But this evening, I remembered that and I thought maybe that had somethign to do with it. So what else could I do? Bang the phone on the ground again. So I tapped it a few hard times on the ground and sure enough the lights on teh bottom on the phone came on and it booted up and has stayed up.
Apparently the drop this morning has done something inside the phone. Do you guys have any idea what this could be? What could dropping the phone have to do with a boot loop and what could be solved by banging it on the ground again?
Maybe it is luck, but it is working. I just feel it will happen again soon as something is wrong inside the phone.

Oh, okay, cool. I always do it how I described, so it must work either way. I was just trying to help the OP not go into the battery charging screen.
And to the OP: Bummer, it sounds like you have some busted hardware, but hopefully it will keep working now.

loose connection insider vs corrosion issue I mentioned to you earlier.
if you're under warranty, flash a stock package and warranty.
if you're not under warranty, learn how to drop your phone correctly.

Oh my god. the same thing happened to me last night. I've been searching all day trying to figure out how to fix it and I came across your post saying you just banged it on the ground a few times and it started working. I did the same thing and sure enough, it started working again! It's so weird. What I don't get is that I didn't drop my phone at all yesterday. It just did it randomly while i was texting.
So my phone battery was dieing. In fact the phone powered itself off. So I went to plug it into my car charger, but the charger port (on the car adapter) was damaged so i never plugged it in. Instead I grabbed a usb charger out of the glove box that I had bought on ebay and never used before. I plugged it in, saw the big battery icon and a few seconds later the phone booted up and I saw the HTC logo. I left the truck and went back to work. When I got doe about an hour later I discovered the charge light on the phone was no longer lit and the phone would not respond to pushing the power button. At this point I figured I killed the battery and would need to try to charge it manually when I got home.
Upon getting home I put the battery in my wifes inspire. It curiously charged it up no problem. So I put the charged battery back in my phone and nothing. It wont do anything. I tried her battery, nothing. No lights, no vibe no nothing. Like the battery is completely dead... But its not.
I actually just bought this phone used about 2 weeks ago its been workign great until now. Im really bummed. I had 2 atrix's get the boot loop problem and another phones screen went. All in the last 3 months.. so annoying.
Im figuring that the usb charger might have an over-volted output and somethign got fried? I have no idea but if anyone can help me that would be great.. I've spent almost 400 in phones in the last 4 months
Thanks!

Also all covers must be on (sim) (battery) to turn on. Sorry dont know what to tell you, phone may have bit the dust. When you left it in the truck charging was it a hot sunny day. You may have damaged internal hardware. If you purchased phone on ebay open a claim against seller. I had a phone I purchased for 400 that kept frying the battery. Ebay made seller refund money back.
See if you can hboot power up holding power button and volume down button at same time.
After my issues with my One X, my daughter looks to have bricked her One S after dropping her phone in the sink....
Early on Saturday morning my daughter ran through shouting that her One S had just fallen from her pocket and landed in the sink. It was in the water just a second or two. She brought it straight through to me and it was working fine, but the phone was on a constant vibrate. I pulled the sim, and removed the top and bottom cover, and got the hairdryer out. I dried it on cold for 30 minutes (no heat at all) and put it straight in a sealed tupperware box of rice in the boiler cupboard. I had expected to pull it out this lunch time (a full 48 hours later) expecting it to be fine, but after plugging it in to charge on the mains for 4 hours, it wont boot.
At the moment it flashes green and red when on charge, but this disappears when it is removed from charge. This is the same whether it is charged via USB or mains.
When I first tried to start it up, the screen flashed around a third of the way down and the nothing.
Second attempt, I held down the lock button and held it. After a few seconds the three buttons at the bottom flashed 15 (I counted them) times and then nothing.
Third time, as above, but flashed 5 times.
Since then nothing. No flashing, no noise, blank screen.
Incidentally, when it seemed to want to boot it never vibrated (if that helps the diagnosis?)
I haven't got the tools, so I had planned to pick some up tomorrow and order a replacement battery from Ebay. My reasoning is because I have read that the lights I have flashing relate to battery issues.
Any other options? Is there any hope for this phone now?
AW: Water damaged - now flashing green and orange. Wont turn on.
Does it geht recognized when you plug it into you computer?
OK I don't know of it even gets recognized if its turned off, bit its worth a try.

It could be that the device has 0% battery.
Try to plug it in the charger and hold the power button for so 15 min.
Then try constantly to turn on(plluged im the charger)
This should help

No no no don't plug it in! There's likely still water in there that could short the circuits and permanently damage the phone, if it hasn't happened already. Power it off fully, put it in rice or some sort of dessicant, and let it sit for at least a week. The longer you wait, the better chance you have of saving it.
Thanks guys for the quick replies.
The phone won't connect to my laptop or computer and won't let me access HTC Sync. The 3 lights at the bottom will only flash when the phone is plugged in, if I unplug it won't do anything at all.
I can't see there being any liquid left in there at all. It was thoroughly dried with a cool hair dryer (and worked perfectly) before I shut it down manually and placed it in the rice for 2 days. I think that I'm at the stage where I can be confident of that.
Sounds like a dead battery to me.. But just to be safe wait a while before charging it

Update:
I was ready to bleach the water marker and/or get some phone insurance, but when I went back to the phone a couple of days after my last post, I plugged it in to charge again and when I checked it a couple of hours later it was working.
it's well over a week later, and there are no obvious I'll effects now.
I'm really surprised, but obviously delighted.
Hi
I bought my relay from ebay http://goo.gl/GbQ1Nt just started using the phone today.. I put my SIM card of a carrier from Peru and it worked just fine. Everything was running smoothly.. I was making phonecalls and texting.. I put my gmail account and started downloadign some apps..
After a couple of hours, the battery was almost dead so I plugged it..
After five minutes, the screen turned off out of the blue.. and I haven't been able to turn it on since
It won't turn on, nor enter recovery or download mode
I'm not even sure it is charging.. when i plug it the red led turns on.. but there is no other charging indicator..
I'm in Peru so returning it is a bit o f a challenge.. I was just wondering if any of you guys know what could be wrong..
Thanks

The link you posted for the auction doesn't work. Wanted to check if you got it new or used. One thing I've noticed with mine is that I have to hold down the power button for a second or two to get it to turn on (seemed like it was a little bit longer than other phones I've had).
Outside of that it sounds like it might be some kind of hardware problem. Might even just be a bad battery. One thing you could try is using an external charger for the battery if you have a universal lithium ion charger or if you know someone who has one. That way you might be able to narrow it down to a problem with the charging circuit in the phone.

thanks for replying
I've edited the link
I tried an external power bank but it didn't even turn it on.. so I narrowed it like you said to: the battery is so messed up it won't even charge or the battery is fine but the whole charging circuit is wrong.
Then I took it to an electrician and he said the battery had energy and should start the phone, but it didn't.
After that he charged the battery alone for a little bit with his "whatever kind of car-battery-like thing" but it still was not turning the phone on.
When I came home I plugged it once more to the external powerbank and some how the charging animation appeared..
I let it charge for a while but it didn't seem to progress, so i turned it on and holly crap it turned on
but after the boot animation it vibrated and turned off and now it's not charging again
man.. i thought i had it
any thoughts?
i've read about something called sticky power button.. its a hardware problem in the galaxy sII model.. could it be related?
Not sure about the sticky power button I've never had it happen to me. I would think that when you had it on it would have popped up the reboot menu like when the power button is being held down. If it were me I would contact the seller.
i returned to the electrician and he recharged a little bit more the battery..
this time it did turned on and it reached the lockscreen it said 1%
so I plugged it.. and it now stays on.. and it says charging but stays at 0%.. doesn't advance.. is it a battery issue or a charging circuit issue?
forget about the sticky power button
Never thought I would run into this moment that I need to ask for help on the forum, but I guess this is my last hope.
Here's the story:
I was on Oreo firmware and thinking of going back to Nougat because there are some apps only work on Nougat at this moment and I overall prefer Nougat design.
My phone was on S-off so I thought it would be perfectly fine for me to just flash Nougat firmware then flash the Nougat rom I desired like the good old days.
So then I launched Sunshine app, passed the compatibility test and the phone rebooted to download mode with S-off shown, everything was working fine so far.
And here was the problem happened, I typed in the command"fastboot flash zip firmwareXXX.zip".
Terminal showed error needs to reboot and flash again immediately as normal, the phone rebooted but never come back to download mode.
Now it only stays on black screen, if I tilt the phone a bit I can see the backlight glowing.
I've tried hard reset by holding power and volume down, it will reboot but still stays on black screen, neither system nor bootloader is accessible.
Even plugging to the computer detects nothing, not even QHSUSB_BULK mode.
However, the phone is able to charge though, I hook up the usb cable with a digital meter and it shows 5 volts and 0.5 amp.
I'm running out of solutions, I've searched through the entire forum and see no one has the similar experience.
This is the first time I hard brick a phone, been a loyal HTC user since good old Desire HD days.
If anyone has experience or solution for this, a kindly help is appreciated, thanks!

Have you held the power and volume down button both together for exactly 1 minute,
I have a u11 that took for ever to reboot with corrupt os youll notice the capacative buttons start flash if its doing something or going to reset after about 30 seconds if not and nothin happens
Take the backing off and unplug the battery,
To do this heat the backing up with a hair dryer and get some really fine guitar picks, work your way arround slowly, in my case the U11 was not glass backed only plastic and was original backing ive heard they are glass now though so be careful,
Now with the backing off and exposed, take all of the 5 or 6 screws out from the plastic ariel cover with NFC chip attached (chip is gold bend it up off battery it is not glued down)
Then from the left of the device at the bottom of the plastic cover with ncf chip on it you should see a slight gap where the vibration motor is located and sits
Get a rounded pair of tweezer and insert just the tip into the opening and very carefully pry it up, it make take a while as some of the adhesive from the backing will be holding it down,
After that is off you have now exposed the devices PCB,
From the battery youll see the connector making its way to the PCB port disconnect it and reconnect it now try to boot directly to download mode with
Power
Volume down
Both at the same time, if this did not work the disconnect the battery again and wait 24hrs for the static electricity to disperse and try again, had this work on a completely frozen unresponisve evo 10 and u11 + and also my U11
Still no luck id say the emmc on the board has gone haywire either that or possibly one of the thermal transistors has blown in which youll see either black and burnt or white and powdery,
Im a phone tech you shouldnt have any problems doing all this just take your time,
Good luck mate

I've tried holding volume down and power buttons both for around 5 mins, no capacitive button blinking.
However I can tell the phone reboots several times during the procedure by seeing the backlight goes black and light up.
And about the reconnect battery route, I guess I'll just do it anyway, since the repairing price might be the same as buying a new one.
Thanks for the reply, mate!

Sounds like the logic board is trying to initialize but there isnt sufficient power to boot it,
its kinda like when you take the battery out of a phone then plug it on to charge without a battery and there is nothing but a lit up black screen and nothing else happens as theres not enough power to boot, this sounds the same to me as there are no red or green light after the orange when plugged in,
Get a hair dryer and heat the back of the phone up a few times and then plug it into charge to see if you cant boost the cells back to life, do this a few times,
If no change id most certainly suggest removing your back cover and unplugging and replugging the battery, once unplugged leave it for a few minutes, then plug back this will refresh the chips (especially emmc as this contains your entire system and bootloader, including download mode, RUU mode)
as soon as battery is reconnected plug it in on charge and try to boot it to download mode straight away also look for any change in the batteries light colour and any blinking,
the orange light when first plugged in is normal but should blink once or twice only then change to a solid red for discharged and charging or solid green green when near on 100% charged
If the above does not work disconnect the battery for 24 hours and try again, this will fully drain any static electricity in the device that may be lingering,
If still nothing after the 24 hours buy an OEM battery from ebay and install yourself, once you have the back cover off youll see the battery takes up 3/4 of the phones actual internal size,
Same as the back cover get your hair dryer place a shamwow or thick cloth over the PCB board then heat the battery up (NOT TO MUCH THOUGH only so its hot to the touch), then with the really thin guitar picks again (they should be bendable easily and flexible) work your way around the battery to cut through the adhesive securing it down,
CAUTION be very very careful the adhesive is strong keep the battery heated at all times to avoid pericing the battery and or damaaging the lcd as this is what its secured to, just take your time and work slowly do not force it out, once all the adhesive is cut it will remove easily by using the guitar pick insert between battery and housing and gently turn the pick from left to right and will pop out, (you will see the battery move when using pick from left to right if not you havent cut the adhesive properly work around the battery once again until you get movement from it)
Sorry for the long reply haha but dont send it to htc they are absolute rubbish hope this helps ive tried to be as detailed as i can its actually alot harder trying to explain it than it actually is to do it

Same as the back cover get your hair dryer place a shamwow or thick cloth over the PCB board then heat the battery up (NOT TO MUCH THOUGH only so its hot to the touch), then with the really thin guitar picks again (they should be bendable easily and flexible) work your way around the battery to cut through the adhesive securing it down,
CAUTION be very very careful the adhesive is strong keep the battery heated at all times to avoid pericing the battery and or damaaging the lcd as this is what its secured to, just take your time and work slowly do not force it out, once all the adhesive is cut it will remove easily by using the guitar pick insert between battery and housing and gently turn the pick from left to right and will pop out, (you will see the battery move when using pick from left to right if not you havent cut the adhesive properly work around the battery once again until you get movement from it)
