Need some advice to fix phone

Thank you in advance for any help!
So I flashed my phone (with the newest RomEo ROM) and everything installed correctly. After install phone starts up and I calibrate my stylus. It then proceeds to install some stuff automatically and reboots on its own. Everything is still great. On restart I'm asked for my sim so I turn off the phone, throw the sim in, and then.....NOTHING. Phone will not turn on or respond to anything. Any advice?

Did you hard reset after flashin the rom? (when you got to the calibrate stylus screen)

Damn. Forgot. Any solution?

Im not sure, Ive heard that if you can get to the bootloader screen your ok. I would suggest just trying to flash again.

First, thanks for your input thusfar.
I would try to flash again but the phone is dead. It doesn't turn on at all and it doesn't sync with the computer. Hell, it doesn't even charge. I just bought the phone from AT&T the other day so I guess I'll walk in and tell them it died and see if they give me a new one, unless I can fix this thing tonight.

i dont know if this would be a problem but do you have HARDSPL on it? and maybe you just have a bad battery. Might want to test that first before taking it to the store and them getting it to work and then see the new ROM and void the warranty.

Im new to all of this so I dont know what advice to give. Did you pust in the Roms thread?
Since you have flashed a new Rom your carrier may not give you a refund.
You did flash GSM rom to a GSM phone and not to a CDMA one right?

he flashed the right rom because Romeos does not have a CDMA rom. I just hope he had hard spl. I mean i dont know what would happen if he flashed a rom and did not have hard spl. I dont know if it would even let him flash the new rom with out hard spl. So that is one possible reason i can think or his battery might have just given out. Since he says nothing turns on and it does not charge.

I do have hardSPL. I check and double checked that everything was the right version and everything was compatible. I'm hoping it's the battery but it's so weird if that is the case because I just got the phone a few days ago! Well, I guess I'll roll the dice and take the phone in and try to get a replacement for either the battery or phone.
Thanks for the input everyone.

If is was the battery, though, shouldn't the phone still boot up when it is connected to the power, even if the battery is dead? If you take the battery out of your phone and connect it to the power, does it still startup?

Nevermind. I took the sim out (again -- for the 10th time) and played with the battery prongs and, thank god, it worked. Thanks one last time for all the input and concern.

awesome! glad to hear it was just a battery problem

My TF thinks the battery is empty

I am now under the assumption that my TF thinks the battery is dead even though there was a full charge in it before I shut it down yesterday. I have been having issues regarding turning it on and couldn't even get into APX mode. I have just tried APX again and manged to get connected, started to run NVflash, then the screen came on showing the large battery image with the red power amount tne just disconnected. I had the TF on charge all night to so there should be full battery.
Anyone else have this issue or know about a fix?
Thanks

Can you get to recovery? Have you tried reseting battery stats?
Also are you using stock charger or have you charged the tablet with another device?

Cheers for your reply m8. At this moment in time, I can't get into anything. Managed to get APX mode earlier, but like I say, it shut down thinking it had no battery, even though it should have been full. Yes it is stock charger and not I haven't used any other method of charging. I am unrooted and stock so other than using CWM, I don't know how to wipe battery stats. Will wiping Battery stats help? What does it wipe?
Thanks

Well I emailed ASUS this morning and have got an email back from them saying it needs to go for service. Just filled out the form for RMA, now just waiting for return details.
Gutted, not even 4 weeks old.

Wiping battery stats clears the data that the device has of the battery. Its like reseting or recalibrating it if the device's battery level isn't displayed as it should be.
EDIT: Seems you posted before I finished with this one... Since ASUS told you to service it, it might came like that from the start. Good thing you didn't root or install a custom ROM.

Thanks Azureus.
I looked at wiping the battery stats when I first rooted, but wasn't sure what it did so just left it.
Yeah it is a good job it aint rooted. Just wondering now on what the turn around will be. This thing has grown to be like my right hand, lol

Well looks like I am getting a replacement tommorrow all being well. Just got an email back from the place where I bought my TF from and they have 1 left in stock. Gonna leave the RMA ongoing until I have the new one in my hands.
Ooooh, can't wait.

[Q] Wiping Battery Stats?

Hi Guys.
Hooray! My TF finally turned on again this morning after 1 and a half days of not turning on.
Is there any way to clear/reset/wipe battery stats without being rooted. As in previous posts, my TF thinks the battery is dead when I restart it even though it is either full or nearly full. Thought I would try and wipe the battery stats to see if that helps. I don't want to root as I may have to send back to ASUS and if I can't turn it back on again, then I can't unroot.
I haven't been able to turn on for a day and a half, nor could I get into APX mode. I did however get the large depleted battery flash on screen when trying to start up yesterday.

Didn't you get a replaced one?
Battery Stats can be deleted from CWM, but I don't know if there's another way of doing it if you're not rooted. Also if you've got a new device, I will suggest you run it a couple of times to see if it works as intended or not before deleting the stats...

Hi Azureus.
Unfortunately I couldnt get a replacement as the box it came in was somehow thrown out with the christmas rubbish, so they wont take it back. They will only send it off to Asus for me. Im not sure now whether to root and then wipe stats, Just worried it wont come back on at all.

IIRC someone else posted something similar a while back.
Try a factory reset before you do anything else.

Do you reckon factory reset will help? The battery reads fine i android, its just when you try to power up it shows the depleted battery icon sometimes and then doesnt show anything other times, just doesnt start.

I can't say for certainty, I just remember that's what was posted. Trying to find that post but it's buried somewhere.
At the least it doesn't hurt to try a factory reset. If it still doesn't help than you can root after that.
I think your problem is related to the "deep sleep" trouble more than the battery stats itself.

Cheers Baseball.
I was reluctant to do a factory reset as this would require a restart and I really didnt want to wait a day and a half for the damn thing to start back up again. While I was at the shop today, I got them to check the charger, he in turn said it wasnt working and gave me a new one. Strange how my battery was telling me that I had 99%. Anyway, I bit the bullet and downgraded to .19 so I could root again and do the wipe battery stats. Low and behold, after my TF turned off to restart and do the install of the .19 software, it didnt turn back on. So I thought I would plug it in and then press the power button as this had become the norm. To my amazement, after plugging in and before I could press the power button, the TF fired up and continued to install the downgrade. Hooray!!!
I am now just pumping in the last 2% of battery needed then going to wipe cache, date, dalvik and battery, then hopefully, and I say this with fingers crossed, that that might be the end to my issues.

[Q] Damaged Captivate - Any help would be appreciated.

I've searched the forums and have not seen anything quite like my problem, so if I missed an important thread, I'm sorry.
Over the weekend, I plugged my Captivate (using a stock battery) into the official Samsung charger and overnight my roommate semi-dislodged the charger. When I woke up and grabbed my phone it only registered a few hours of charging yet still had almost full battery. Upon rebooting the phone, I was sent into a bootloop. Not at the ROM, not at the Kernel, not even at the bootloader. It goes so far as to show the white loading ring at the center of the screen which never moves. At one point, a thin pink line appears halfway through the screen as it shuts down and reboots, never making it any farther. If I plug the phone in, it will boot normally though it does not accurately report battery levels or charging.
Other oddities: after 5 minutes of a phone call, the phone hard crashes. Not FC's, but just goes black. Upon a reboot, I get stuck into the same boot loop. If I plug the phone into the wall charger without a battery, it will go into the turned-off charging animation and show a 100% charged battery. Furthermore, my other roommate has a brand new i9000 so I tried that battery (again, stock Samsung) and it continues in the same bootloop. I have tried flashing other ROMS and going back to stock, but that does not seem to help.
Other info: I was running OneCosmic's ICS 3.1 with no overclock and light undervolting at the time. It was perfectly stable for the few days until the charger dislodged. I am also out of warranty and am not eligible for a hardware upgrade so repairing my Captivate would be ideal. I also have a usb jig if that is of any use to this scenario.
Has anyone experienced anything remotely like this? If not, what debugging steps should I attempt?

What I would suggest is using one of the ODIN one clicks and flash back to stock
Sent from my SGH-I897 using xda premium

I've flashed back to Rogers 2.2 stock. Doesn't help. It actually made it harder for me to get the phone started though I have yet to make a phone call from it.

Have you had the phone for less than a year? if so call at&t(or rogers) and they'll replace it for you.
then try factory reset
then try using odin or rom manager to flash back to stock
When all else fails, flash to cm7. that will completely wipe everything and start from scratch.
if that STILL dost work.... than you can be sure that its a hardware problem :/ theres nothing you can do except replace and sell for for parts.. sorry

You may want to try clearing the battery stats. Something in there may be telling the phone that the battery is completely dead and it shuts the phone down in the middle of the boot. Just a guess, though.
It sounds to me like the phone might have gotten confused aobut how much battery life it actually has. You might also try getting it loaded up and then letting it drain the battery completely down. Reset the stats and then fully recharge the phone.

I have exactly the same problem, I did the reset of the battery stats and still not working.
Did you solve the problem?
thanks

Thanks to everyone for their suggestions, however, no amount of battery calibration could get it to work. Furthermore, a bad flash has made the situation even worse. Now Im bootlooping even when plugged in and when unplugged my jig is of no help. I have declared my Captivate dead.
Best of luck toominds, if you get it to work, let me know. I'd love to have a spare phone sitting around.

Boot Loop, sort of...

I'm having a weird issue that literally just started yesterday. First of all, I didn't do any changes yesterday before this occurred. Anyway, my G3 just started freezing, then rebooting randomly, BUT that's not all! When it tries to reboot, it flashes the LG screen, and SOMETIMES makes it to the AT&T screen....and even, sometimes makes it all the way booted up. But, at any point, it can/will reboot and start the process all over. I read on another site that it could be a battery going bad, but I only trust XDA. So, could someone chime in with some help or info pointing me in the right direction?
Thanks in advance,
Ontabok

same issue i am having ..i thought about the battery thing so i pulled it out and put in a fully charged one and no bootloop..but now 3 hours later and 85 percent left on battery and bootloops have started again..btw other battery was a 20 percent when changed it out for fully charged batt..so im just as lost trying to figure it out

Sadly that sounds like a hardware issue

How can I figure out what part of the hardware could be causing this? Is there a diagnostics or something I can use? I've tried factory reset (multiple times), LG Flash Tools to flash previous version, and the strange thing is it may not even make it through the process without restarting again. It's been rooted, but I've never had a problem until this. I never deleted anything.

Not really other than swapping out parts. If using flash tool won't work and it won't go back to stock then it's definitely a hardware issue.
What percent does it get too before rebooting? If 80% that's normal. If before it's definitely a hardware problem.

I can try Flash Tools again. Maybe it just didn't take. I just noticed another thing. When it's trying to boot, if the notification light flash when the LG screen is on, it will load. But, if it doesn't flash, then it will just go black, then flash the LG screen again.

Yeah. It's really weird. It seems to do it less when the battery is charged, but if I get down to 40-50%, it could go into a loop that runs the battery into the red. Also, it seems to heat up around the power button when it's stuck in the loop. And, to top it off, my software update popped up yesterday. I've been anxiously awaiting Marshmallow for a while, but I'm afraid to update because of boot-looping right in the middle and bricking the whole thing. I already have a bricked G2 due to something weird that happened while trying to update to Lollipop. I'm going to the AT&T store today, I think. I'll let you know what I find out. Maybe, it can help you.
Thanks,

Ok. So, first of all, sorry for the long wait on a reply.
I did manage to get through a factory reset, but it still is doing the boot loop. I'm going to take it in to AT&T today. You can see my reply above to see more info. I unrooted everything and factory reset, but it still loops. I think it's a problem with the phone. I may have to go to LG, depending on what AT&T says.
Thanks for the help!
Ontabok

So, final update. I had to go into the AT&T tech store. I was having the random boot loop for about a week, then, on Saturday, I got the Demigod green screen. I had went in the day before and ordered a new battery, but I couldn't find any information on the green screen error. I took it in and they immediately (after checking for rooting) replaced it (warranty). They said they had never seen/heard of this screen. They had to actually Google it to see if it's attached to rooting. (It's not) Anyway, so I'm back in the saddle with a brand new phone. ?

ok so my g/fs g3 just started doing this. updated to mm about 3 or 4 days ago. was doing fine. haven't changed anything software wise. completely stock. no root.
what is really odd is that it doesn't loop when plugged into a power source. take it off the charger= insta loop ...
hoping a rom might solve the issue but from the sounds of the replies maybe that isn't the case.
any help greatly appreciated. i've not owned this phone myself or i would already have it rooted and custom recovery..
is there even a root method for MM? recovery?
i'd love to see if its a software issue. the phone worked swell before the update...
im trying to get to the bottom of this tonight if i can my g/f has a final tmr early in the morning and i'd like to make sure she has a phone to go with her. prob send her with mine if i can't get this working. but thats less than ideal PM if you've got anything i can try or links to get me started... i'll be reading in the mean time...
