I've got XT720 around 1wks and root it before, when I use it with many task at the same time with around 60% battery, it sudden switch off and can not restart at that moment.
I tried to recharge & bought a new battery for this but it always no response when I press switch button & I can not entry the recovery mode also, I tried many many times for switch on, I found that I just only can switch on with bootloader mode(press upper volume, camera shutter & switch at the same time) & it only show "battery low, cannot program".
First, I used the desktop charger that I'm sure the batteries got fully charge, second, I tried to put out the battery with a moment & it can boot it normally (just few time only and switch button out of order that I need to reboot again....).
Besides, I used rsd lite for flash rom(sometime bootloader without problem) but it was failed at last step (I'll try to update screen cap later).
I just query bootloader with crash that it can not boot normally, can I update bootloader or it was hardware problem??
Pls kindly help me if any solution, I'm come from HK & I'm not in advance in Eng, pls forgive me if any problem. Thanks for help.

Hi. Can someone please help as I'm new to this this and would very much like my phone to work again...
My Defy kept restarting approximately 5 seconds after starting up. Without being able to access any settings I tried a factory reset via the on button / volume down button. I'm not sure how long this should have taken but decided after a few hours of nothing more than a yellow dot moving across the screen that it wasn't working! Button presses / screen taps had no affect so I pulled the battery.
On powering it up it now either gets as far as the Moto Blur or T-Mobile logos but just hangs there. Further attempts to factory reset give the same result as the first time.
I've noticed two lines of text when accessing the reset screen which read 'E:Can't open /cache/recovery/command' and 'E:Can't open /cache/recovery/caller'. I think these were present at the first attempt but I'm not totally sure of this.
In case it's relevant the phone shipped with Eclair, I changed this to Froyo using the Motorola software upgrade some months ago, it had been working fine since apart from not saving photos (?).
Aplolgies for the essay. Can someone please help?
I have same problem now.....but I didn't find any answer yet. I thought i could be the hardware
Could you try to boot into bootloader then use RSDLite to flash the original SBF to your phone from there? I used to do that in the past with my Milestone.
So, yesterday I decided to reboot my phone since it was very sluggish for whatever reason. I think it shut down properly but when it came back on, there was a very interesting problem that had come up - it didn't boot any further than the logo screen, which didn't even play its standard animation; it just stood there with the LED on the home button changing colors (like normal). I left it on overnight hoping the problem would be gone, but to no avail. It still hadn't booted when I woke up. If it matters, the only thing I can boot to is download mode. It doesn't let me get to safe mode or however it's called (the menu you navigate with volume up/down and the power button). Needless to say, I was very puzzled. Then I went on and tried to flash the latest kdz since I thought that would fix the problem. I hoped that would easily fix the problem. But no, it decided to be funny and give me more headache. I tried using this guide: http://forum.xda-developers.com/showthread.php?t=2409308 but after step 20 the LG Mobile Support Tool crashes and I can't continue. Sure thing, I will try the Upgrade Recovery that the tool has built in. It properly detects my phone, the software download and extraction goes smoothly. Then I reach the S/W Upgrade part of the process. The few first seconds everything is fine, but then the bar reaches 5% and just stops. Just like that. Now it's been 8 hours since I began the recovery and no progress has been made.
Can anybody help me? I'm lost here...

Good luck!
Thread closed.
It started a few days ago, I was testing a cardboard/gear vr unity game and the screen would turn black but the buttons were responsive and I could get it to hard reboot or make it come back again after plugging it back into the gear. I looked around but couldn't find anything that resembles my issue.
Now as soon as it boots it goes into a black screen after samsung and carrier logos show, i sometimes get a glimpse of the lock screen and respond to some input.
The phone is still on, I can feel the battery warm.
-No response to any input. Not even pwr+vol down.
-PC won't detect it when plugged.
-No lights on charging.
-I need to let it fully drain for it to shut down and try anything again.
-Did a factory reset from recovery mode, wipe cache. Still the same.
-No root.
-There was an update that may have installed overnight but can't confirm because can't access system info.
EDIT: New find! when booting to recovery, goes into "Installing Update" and then "No command".
Any thoughts??
Is there some pc software that i can use to try to reinstall firmware? Something like SEUS for sony phones back in the day?
Is odin safe or should i look into a samsung official tool? I've never used odin so i'm not sure of it's capabilities (this is my first sammy phone, I had it to get to test gear vr apps)
Sorry for the long post but wanted to get all the info out there.
Thanks!
Can you enter "Download Mode"? (By rebooting and pressing HOME + VOLUME DOWN)
If yes, I suggest that you try, as you suggested, reinstalling your firmware.
You will have to know your carrier, or specific phone model (G930X, where X represents carrier letter (Example: T for T-Mobile) )
Modified Odin (by PrinceComsy): https://androidfilehost.com/?fid=24591023225177749
Then I suggest downloading firmware from https://SamsungBay.com as all other sources restrict download speed (So it takes a minimum of 13 hours).
https://samsungbay.com/download-firmware/?device=&model=sm-G930&firmware=
Once you have Odin and Firmware, load the correct files.
(AP_G930X), (BL_G930X), (CP_G930X), and (CSC_G930X) into Odin.
Power off phone, and boot into download mode (Pressing HOME + VOLUME DOWN)
N.B/ You will lose all your phone data, sadly, but it seems you've already wiped it.
Hello all
just before i get started i did have a thread here regarding this issue before but sadly unable to find it now so seems i need to start over....
this is more of an update on what has been done so far but will just give detail about the issue from start
when this phone came to me it was not functioning i have no clue to what the wife done to it.... it appears that it may not be charging and something is stopping it from charging..... the charging indicator is on (( orange )) and the battery will display on screen with a lightening bolt in the center.... if i plug into laptop the laptop will sound off the USB connection and disconnection alert will do that 3 or 4 times
pressing power button will make phone vibrate and will display a battery with the lightening bolt assuming that means battery is flat as a pancake
holding volume up and power button brings me into the recovery option total of 3 options show 1) normal 2) fastboot 3) recovery whatever i select say for example recovery it will display the Asus and powered by Android this will last for about 3 to 5 seconds before going off again
so that is the state of the phone as of now and even after other things i have done as i will mention
in the past i have come across 2 phones with the very same issue the first one i flashed my self that phone only shown a charging indicator light but i found the flash tool and rom from the Alcatel website and it fixed the issue so assuming the same would apply with this Asus also the other phone i had with same issue was fixed with a flash
so here is what i have done so far using SP flash tools and following instructions from different places i have successfully flashed over the Stock Rom done it under download only also format + download and even tried firmware upgrade but i am still stuck with the same thing as mentioned above
obviously after flashing the phone it needs to power up to complete the setup process but as is clear i cannot do that if the battery has little to no juice
so what i am looking for is a solution to getting the phone to charge again or a way to charge the battery by other means (( bare in mind this phone has built in battery )) (( battery has been replaced new ))
what could be causing the phone to not charge or at least give battery the power it needs i ask because i do believe the phone is giving the battery some power but very little..... the way i look at this situation is like installing a sound card on a PC but not installing the driver the PC knows the sound card is there but cannot work without the driver same seems to apply with the phone
if i disconnect the battery from the main board the laptop will not pick up the phone even if i press down on the volume down button as i do when using SP flash and the orange charge light flashes so i don't see the issue being with mainboard but more likely a software glitch maybe the MTK chip is not doing its job properly or maybe it thinks the battery has full charge and stops the charger from adding more juice when in fact battery is flat
so can anyone enlighten me to what could be the problem and a solution
thanks in advance

Hello,
My wife's Sony Xperia XZ2 Compact with model number H8324 has an issue with booting or maybe the launcher getting stuck in a loop after getting to the lock screen for a split second.
The phone seems to boot like normal and gets to the lock screen, we are even able to punch in one or two digits of the 4 digit pass code. Then it goes into a loop of the notification bar and back button flickering. From then on the phone is not responding except for the power button which brings up the normal "Turn off, Reboot, and Lockdown" menu. The issue just started out of nowhere yesterday morning and we haven't been able to fix it yet. We haven't done any rooting or custom rom flashing, it's running the official Sony software but it's out of warranty.
Here's a video showing the issue. The video shows the whole boot process but the link takes you to the last part after the logos.
We would love to get some files off it so if there is a way anyone can help us with that we'd prefer it over a hard reset.
Things we've already tried
Turning the phone off and on again
Unlocking the phone in the split second the lock screen works, this is just too short to swipe up and then put in four digits.
Rebooting the phone
Booting while charging
Booting into safe mode (this has the same issue)
Connecting the phone with USB to a pc, the phone is recognized by Windows, but it doesn't share it's filesystem with Windows.
Connecting the ADB to it, alas usb debugging is not yet enabled on the phone
Trying to get into recovery mode, we haven't been able to get into the recovery menu. Googling seems to indicate it might be holding volume up + power button when the phone is off but then it doesn't seem to do anything at all.
We're currently trying to run out the battery of the phone to see if that will resolve the issue on it's own.
If anyone has any idea, we would love to hear it.

I think u just need to reinstall rom file with newflasher and stock rom , did u tried it ? with newflasher newest version , u still can keep the personal files and flash stock rom for the phone , then i think this phone will run normal again
If u dont know how to do that , reply comment here , but u should turn off the phone to keep battery well , if u can't turn off the phone , try to press and hold volume up button + power button within 5 sec , phone will vibrate 3 times and totally off
Is there a way to get a stock recovery if somehow the recovery has been deleted?
