Connect to computer and hold down both volume keys
If that brings you to the download mode you can reinstall all your firmware using odin

i have the a207m and unfortunately it did not work thanks anyway
so i could actually see it turn on and got the unlock screen and saw that battery was dead and did not have a charging symbol it turned off 2 seconds later. can it be the baterry that causes this?

It can be the battery but it could be a dirty charge port or even cable. When the battery is extremely low you're not going to be able to flash it, nor should you try. See if you can get anything out of the charger connect area on the phone.... maybe it's lint.. At this point there isn't much else besides ensuring you have a clean connection.

[Q] Phone won't boot - Sapo a5 ZTE Blade

Hello, new user here, I have a technical problem and I could use some advice. If I posted on the wrong thread or if this is already solved, please forgive me.
Anyways, It was like 02:00, my phone was at around 38% battery at the time, I figured this would be enhough for me to make a backup of my CM9 ROM and then restore CM7. I set Clockworkmod to backup CM9, and that was successful. Then I restored CM7 from a backup of it I made earlier. I think it was successful but I fell asleep before I could notice. (Staring at clockworkmod restoring data puts you to sleep) It most likely ran out of batteries after completing the restore in Clockworkmod.
When I woke up today, I found my phone shut down and with no battery. I proceeded to plug it in to my PC. No charging... I saw that was wierd, and then when I tried again I figured out my phone was essentially dead.
Here's the problem, when I press the power button, it vibrates successively, and shows no signs of booting. I began reading forums, including Modaco (I had to use google cache because it just happened to be offline at the worst possible time), and they say that it's because the battery is dead. So I put it in my wall charger. After an hour or so, same problem. No boot, always vibrating in succession, and also even though I press volume up and down I get no signs of clockworkmod.
When I plug it into my USB, strangely my mouse disconnects from my PC. I use a laptop, and this never happened before today, and it is possibly related to my problem. In short, Blade plugs into USB, Mouse dead.
I don't know if my phone is refusing to charge or if it's bricked, I can't tell, and I really fear it may be bricked, because I can't afford a replacement. (No job, still living with my mom, I'm 19) I also have no clue if my computer can even recognize it, nothing shows up except for this wierd mouse problem.
So, can anyone help me?
Connect charger with blade,then boot into recovery....
Is it booting into recovery?
Nope
Nope, I wish. : ( When I connect it to the charger and try to turn it on, it only vibrates, nothing else, no recovery, no Android logo.

Do a tpt or use the adb method.. I experienced this issue before.. after tpt,it worked fine..
Sent from my ZTE Blade using XDA app
Okay
Very well, I'll go look it up. If I have any doubts I'll post here again.
Uhhh
Well I tried the TPT method, I did the manual steps as described in a website I can't link to because I have too few posts ( : ( ), and the phone does nothing, it just keeps vibrating in succession as I hold the power, volume buttons and other buttons, even with the TPT in my SDCard, is there anything I'm doing wrong, and how do I do the ADB method, is there a basic tutorial on that that's easily explained? Thanks in advance.
EDIT: I've got dim signs of life from my phone as the red led light appeared for a brief moment. I'll see what happens next.
FINAL EDIT: After a while of waiting, the red light greeted me again. And I pressed the power on button and my phone turned on like normal! : O I didn't even need to TPT! 1% Battery... My phone scared the heck out of me by being half-dead... Note to self: Never let your phone discharge too much.
Somebody close this thread ; D
my mobile having same problem

N4 Bricked!! No responses! Just red led when I plug in to AC/USB

Hello guys, first than nothing, sorry for my bad english, isnt my native languaje. I got this problem yesterday in the night of the new year!!!!!!!:crying: I was rooted, using Xylon and Faux Kernel, but the problem appears from nothing!!
The first thing that I detected was, the phone take a WHILE!!! for charge.... then, out of the power, the phone get overheating and discharging so fast, never in life that happends, when N4 got discharged i try to turn on again but download mode appers in the screen, finally I get in the recovery, then I did a wipe cache/system and factory reset. Install again the Xylon... but when phone finally turns off, when I plugged in to AC absolutelly nothing happends, the led just turn in red, and the N4 dont start in FB, dont get charge, dont do a sh*t !!!! I conect it to the PC but also nothing appends, the N4 doesnt appear in my device list.
So... my N4 its broken?
There was possibly something wrong with the kernel and rom combination that caused your phone to overheat. I think eventually the heat may have damaged your hardware. Sorry but, if something was wrong in the first place it was not a good idea to reinstall the same thing that was causing the problem, if I were you I would have flashed a stock ROM. My only advice now would be to RMA it and pray
EDIT: I found this if it helps at all:
If you are unable to access the settings menu of your device, you can still reset your phone by performing a Hard Reset. Here are the instructions:
If your phone is on, power it off.
Press and hold Power until the device powers on, then immediately press and hold Volume Down (while still pressing Power). You will see the word Start with an arrow drawn around it.
Press Volume Down twice to designate Recovery mode.
Press Power to restart into Recovery mode. You will see an image of an Android robot with a red exclamation mark.
While holding down Power, press Volume Up.
Use the volume keys to scroll to "wipe data/factory reset" and press Power to select it.
Scroll down to "Yes - erase all user data" and press Power to select it.
Note: If at any point during the above steps your phone becomes unresponsive, you can restart it by holding down the power button for several seconds.
Before you try anything else, try and leaving it plugged in for a while and then try turning it on. Or leave it plugged in to a computer then try turning it on.

Try this. I haven't had it happen to me, but I do have a friend who this exact same thing happened and he thought it was bricked. He left it plugged into AC over night, and in the morning it would turn back on.
First than nothing, thanks for reply, I appreciate your intentions to help me.
I will leave it charging all the night and while Im working too... I hope after that, the phone at least turn on.
I dont install the STOCK ROM because I dont have it in my internal memory and I was in my girlfriend house, the night of the 12/31/12, there is not much to do...

It could be bad battery, how long did bought of you had working phone, how many times did you charge?
Did you use out of the box charger?
Did you have problems with usb jack?

I bought it the 13/nov..
I received it 29/nov.
I ALWAYS use stock charger, only 1 time i try to charge it in my car, but it was less thant 5 minutes, I decided dont charge with the car because the energy variates when I accelerate...
After that, I use my phone quiet normal.
I had this problem with my nexus 7. I think my battery died all the way and it couldn't charge. The stick charger wasn't doing anything. But I plugged it into my computer for a few minutes and tried turning it on. Then when the loading screen appeared I ran it to it's stock charger and charged it to full. Your battery probably died. Try different combinations of ways to get it to take a charge. Just long enough to turn on then plug it into its charger. Though the overheating could have fried it

my device has just quit workin all together

my att g2 4.2 rooted stock rom worked normally last night, this morning I plugged it into the car charger and it displayed it was charging with 2% charge present. I pressed the power button the boot animation began I set it down and when I picked it back up a few minutes later to use it...well nothing...the charging indicator led wasn't lit and when I pressed the power button LG appeared for only a split second then went black. when I plug it in same thing, LG logo for a brief second then disappears. I haven't done anything recently except xposed modules, no flashing of anything. any ideas? thank you guys
It happened to me (on other devices) when I let them discharged too far. Just allow it to charge awhile then try to hold the power button
for 10-20secs ... The NookHD+ were the worst in this situation (it won't charge sometimes, I had to plug/unplug a few times to initiate a charge, I was almost about to RMA one of them).
something else that's odd
when I plugged my device into my laptop the laptop acted like I just plugged in 12 different things that all needed to have their disk formatted. what is going on? wierd

try charging the device in offline mode ( turn it off and let it charrge for a while) and then turn it on . mind wouldnt turn on because of very low charge yesterday. doing this helped
update
I let it charge for several hours, nothing...it appears to be in some kind of boot loop. I can't turn it off all the way, I hold the powwer button for tensec or so and the LG will appear for a second then disapear and then the back light stays on. oh ya, when I plugged it in a few hours ago it wouldn't turn on but the red LED was flashing. I'm not sure how long it stayed on, but it was off when i got back to it several hours later. thank you for your time fellas!
If you can get to recovery at all, leaving it on charge in there. Has saved me in a similar situation.

Could have been the power switch that makes the phone short circuit and goes off anytime.

Thank you sirs, unfortunately still no good
it sounds like you had the same thing as everyone else yesterday that had twrp installed and the carrier automatically updated the system.
I could not get my phone recognized by the laptop and had to use pdanet drivers, which finally worked, but I still had to dig for the device. then had to flash back to stock. There is a pretty good thread on this topic, already. Search for it in the developer section. Do not skip any steps, such as setting the date back to jan2012 and turning off the internet. go slow and methodically, or you will miss a step and get frustrated.

My g900F is Hard Bricked - Help me please

Hello.
I've flashed my s5 with popwizh and everything went well. But after a full battery discharge the phone won't turn back on.
Battery is good and charger.
volUp+home+power doesn't do anything
volDown+home+power doesn't start download recovery
tried to boot from sdcard with a debrick img but no luck.
What more can I do? I don't want a paperweight please.
Charge it?
Battery is good and charged
If you can't get it to even turn on or enter download mode, there's not a lot you can do
Try removing everything like SIM and SDCard, remove the battery too and only connect the charger, see if you can get any signs of life at all
If not, it sounds like a hardware problem
Its to much of a coincidence to be a hardware problem, I refuse to give up just yet.
So far all the posts that resemble to my situation go on an on about flashing a debrick.img to the sdcard and boot from there. Dead boots and stuff.
I did this: http://forum.xda-developers.com/galaxy-s5/general/g900f-debrick-img-lollipop-t3240626 but without success
You said it won't even power on ?
How you going to flash anything without power?
I'm not saying 100% this is the problem, but most devices die when they are powered on, as that is when they are put under the highest stress
For example, I put away my treadmill in the corner of the room about 6 months ago, working - came to use it a few weeks ago, dead
Looks like pixies killed it, but actually it was when it was powered up again, just looks like it died when it was off
--
Is the phones power button working?
If you at least had a sign of life, we could go from there, but without any power at all, I have no clue
Battery connection contacts not bent or snapped?
From what I understand the phone won't turn on because the boot partition is gone, so if I manage to boot from the sd card to the download recovery, I can then use odin to flash it back to stock android.
Am i wrong?
Are you even getting the logo on screen when you turn it on?
Does the screen even light up?
You said there is no power at all, that's not a boot partition problem
Man if it's not turning on and there's no reaction when you press the power button then there's two things I can suggest : the power button is not working; or when the battery went completely dead its safety system thing could have turned on, which means you have to put it to charge as long as it takes for it to turn on again. Plus if your phone was exposed to water which I doubt its power controller could have gotten burnt
Have you plugged it into a pc? See if it registers with that and if it dies but still doesn't boot just try to leave it on the charger for a few hours even if it's fully charged. Then battery out for 10 secs wait... wait... wait... and turn it on plugged into the wall. Or at least try. If that still won't work samsung repair Centre for you
Still no life, I've tried everything said so far. My only hope is a debrick.img to boot from the sd card, which I don't have.

What did you do to 'reset'?
When I've had similar issues, I've held the power and volume up buttons for over a minute and eventually it turned on. If not, then volume down and power for over a minute. If you haven't, try that with and without the charger plugged in.

Mine does this all the time if I let it die you gotta have the oem charger if I recall correctly wish I could find the post about it I wanna say with oem charger you hold vol up or down try either while you plug it in and if you get the charging graphic you wanna then leave it charging for a while then retry the power button it's stuck in some sort of Sahara type mode from what I could see when that happens...let us have a bit more detail when it's plugged in do you see the charging graphics at all? If not and only seeing the LED light I'd bet it's in the mode others have mentioned here if you do then I am not certain but other times I had same prob just left it on charge for couple hours then it finally booted.

I am facing similar problem with my G4 Plus. The difference is that my phone kept on hanging while doing normal tasks and then it used to restart. The weird thing was that while the phone booted up, there this boot animation where a person is doing flips there my phone used to hang and then it restarts. Only after that it used to completely boot up. But after 10-15 mins of usage it used to hang and restart.
One more weird thing that used to happen is that with every restart the battery used to drain drastically.
Then finally the phone died. And while charging the white led kept on blinking.
I took my phone for repair and even they were not able to figure out the problem. They replaced the battery but still the same issue. At the end they said that the problem is with motherboard and needed to be replaced.
Now I'm using Honor 7X but I still have my G4 Plus with me.
If anyone was able to boot up his device then please do reply on this thread.

Hmm, have you tried a firmware re-flash? Here's a stock firmware that should work on XT1643 devices - https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138 You do not have to re-lock the bootloader if you do not wish to (skip the OEM lock begin and OEM lock commands). I would recommend a full device wipe though (using the 'fastboot erase userdata' command) unless there's crucial data you still want to try to save on your G4 Plus. A full wipe however with the full flash should help us troubleshoot.
However, if a firmware flash doesn't work, then it does start to suggest there is a hardware issue. Do you experience reboots if booted to the bootloader or the recovery?
Also, do you recall if the hangs were random or were in a particular app or with a particular task?

I tried to boot my device to fastboot after one and half month, as I was busy with my exams, and fortunately today it booted (Earlier it was not at all booting). But the hang and reboot problem still persists. So, now I'll try to re-flash the firmware and then I'll update about the status.
Currently my device is running on December Patch Firmware.
No, till now no reboots in bootloader and recovery. And yes, I forgot to mention, my recovery is stock. In December I went back to stock from rooted. But the bootloader was not locking. It still has that warning at the starting of boot process.
The reboots were random, it still are. The device is rebooting within 5 minutes of reboot.

Sorry for late reply, I did tried it and also tried to replace the battery but it didn't boot up. So I took my phone to Service Centre where they kept the phone for 2 days and returned the phone saying that the problem is with the motherboard and it has to be replaced.
Hi,
I have a problem with my G4+.
The screen looks black even when turned on however when I shine a torch on the screen I can vaguely see the graphics but not enough to do anything with the phone.
My son suggests a problem with the back light. Is this a known fault and can it be fixed or is it a case of a new phone.
Thanks for any suggestions,
Martin
i got solution
the problem is a flex, it is the one that contains the camera's flash, that flex has a small resistance, when it dies the phone stops charging, your phone is not briqueado just does not charge. replace that flex and the phone charging again

I am facing similar issue with G4 plus. phone's battery was low to about 13%, and was heating up in charging, so i thought to switch it off for faster charging. but its not booting up back after that. white led near fingerprint sensor keeps blinking when i put it to charge. i read this thread and tried the methods of holding power button, or power+volume up, or power+volume down, or power+volume up+volume down. but nothing works. i did all with and without charging. tried all these last night and this morning as well. meanwhile i left the phone in charge over night, for approx 8 hours. no charging screen, not booting up. now what ??
It's the battery.
Go to your nearby Motorola service center and either get your battery replaced, or ask them to boost your battery (if it works you'll save money.)
