[Q] PHONE is Dead, Not charging at ALL, No custom rom installed

Hey guys, i've done the search button and still can't find any answers. First of all, all i've done to my phone : S-off, superuser, root. No custom ROM installed. i did that 2days prior yesterday and it was working and charging fine. So yesterday when i was playing paradise island my phone died. I connected it to the USB wall charger and left my room. After 3-4hrs, my phone is still dead. So i thought maybe the USB or wall charger is not working. I tried using my cousin Mytouch wall charger with the htc USB, still doesnt work but using my wallcharger with the mytouch usb, my cousin's phone charges.
When i try to charge my phone, the amber light comes on but its flashing, then after 3 times, light will stop
Troubleshooting i've done
I've tried numerous times to go to HBOOT, nothing
Removed the battery several times, nothing
tried USB charging through my laptop nothing.
Any help guys??

Same issue!
Please help with this!!

CMW
If you search you'll find that there is a problem and after installing CMW Recovery most phones will not charge if they're off, so if you let your battery drain to the last you will be unable to charge your battery trought the phone, no solution at this moment for this
Work arounds
- Charge your battery on a wall charger directly not trought the phone
- Charge your battery on an stock untouched Sensation

Wallcharger, is there one i can purchase??
Is the battery itself the problem?? because t-mobile, will sent me a new battery. I've only had this phone for 3 weeks. IF the battery itself not the problem, they will send me a new phone but i'm assuming that i've going to have to send the old phone back, is there going to be an issue regarding the warranty when i send the old phone to them???

it's not the battery, it's the cmw what's the problem. You have an older version of cmw.

I see, where to get the latest CWM? There's a way to go back to stock right?
Now i kinda regret S-OFF,ROOt, CWM ...lol..-.- i know it's my fault tho...

Once you managed to boot the phone again, you can install rom manager, from there you can easily install the latest cmw.

i have the latest CMW Still doesn't charge when battery at 0%
You would think they would test CMW before releasing....

I used CWM 4.0.1.4. From what i know its suppose to fix the charging problem. As of right now, im trying to manually charge my battery by splitting on of my old USB cable +wall charger. So hopefully this will work.

None of the threads in the entire forum are even remotely helpful if you can't even get the phone to turn on.
I can't reflash the recovery - if there is no way for me to get into the bootloader.
A wall charger hasn't helped - nor my N1 battery taped in.
NOTHING.
Please stop jumping a million steps ahead to reflashing the recovery - start with HOW TO TURN THE PHONE ON - bearing in mind that NOTHING IN THE FORUM so far has worked.

I've been using my brothers G2 battery (which doesn't fit) to turn on my phone.
But since I don't have a universal charger, and my phone wont turn on (I tried EVERYTHING) than there is no point to attempt to get into recovery unless I'm going back to stock.
Tl;DR CWM Needs to fix there shhhhhheeeet.

I finally manage to turn on my fone by splitting my old usb cable...i know somone said, its dangerous but it work for me....so do it at your own risk....now im juz looking for a safe wayto revert to stock w/o cwm,root,super user....might keep S-off tho
Any suggestion
If u need to start you fone....get a spare usb cable...and split it..remove the battery from your fone. Now tape the red wire to positive and black to negative....attach the usb to ur wall charger.....then wait 10- 20 min. Now remove ur battery then insert it back to you phone and turn it on. Once it starts, connect it to ur htc usb+ wallcharger.... once again, someone said its dangerous....so make this your last resort

Yeah. That didn't work for me. After splitting two cables - I decided to cut my losses.
Unfortunately I'm not in the US - and that's where I bought the phone. I'm going to try and find and independent vendor and see if they have a battery I can buy.
If not - I am ROYALLY screwed.

Yeah the battery/cwm combo is ****ed. So angry.

Do you have the one with the blue text? It's supposed to fix these issues
Swyped from my HTC Sensation

Sorry to revive this thread, but I am in the same boat. After trying to flash android on my brother's hd2, I noticed that the battery died. I cannot charge it since it has no ROM currently installed... Has there been a fix?

[Q] Phone dead, but the problem is not the battery

Last night I changed the SIM of my Nexus S, put back the battery but did not close the phone with its battery cover since I was going to change the SIM again soon after. I turned the phone on, but the battery fell down and obviously the phone turned off. However, when I tried to put the battery back and turned on the phone, it did not. The phone seems dead and I'm pretty sure the problem is not the battery as it has always been working fine. Any help?

No charging animation right? Same here. it seems we have bricked our phones beyond repair.

Cache?
I am not too sure if this would work but try these steps however this will only work if you phone is rooted (ONLY UP TILL STEP 5, AFTER STEP 5 ROOT WILL BE NEEDED):
1) Pull of the back cover of the phone and then plug it into the computer via a usb cable
2) Hold down the power button for 15 seconds, in some lucky chances the phone may turn on if not continue to step 3
3) Pull out the battery but keep the usb plugged in DO NOT UNPLUG
4) Now hold down the power button for a further 15 seconds, in some lucky chances the phone may turn on if not continue to step 5
5) After this unplug the phone from the usb, reinsert the battery IF YOUR PHONE IS ROOTED attempt to turn it on but holding the volume UP button and the power button then navigate to the recovery section from here clear your cache then attempt to turn your phone on. IF YOU PHONE IS NOT ROOTED you can only try and turn it on the normal way (by holding down the power button).
Hope this works for you.

mine too, pulled off battery after it hang, and now it can't be turn on.

nope, didn't work for me.

JUST STOP !!!
My phone is getting scared.. :laugh:
Do you know how many times i've just pulled the battery when it hangs, or I was stupid and didn't have on the back cover, or it Was wednesday and I was bored?.. Here my phone is, all in a panic, and I'm afraid to pull it's battery to ease the pain of it being frozen, or pull it's battery when it gets sick with a bootlooping bug.. How am I supposed to pull the battery when my hands are shaking and my mind is telling me NO, but my heart just wants to help?? How am I supposed to look my phone in the camera and say, "I can't help you"??
I just can't do it,..
I just can't..
:crying:
:silly:

This sh1t happen to me last night, from my research the emmc is bricked the phone needs a new emmc or a repair using a tool like riff box or an external programmer of a kind.
The cost for this operation is really high i will try to do it with a simple smd work station and see how it goes
@mimimouchi if u don't have warranty, u will have to pay a huge amount to fix the phone which doesn't worth it if u take into consideration the current price and age of the phone
Why this happen on samsung mobiles ? is this company going down ? ffs

From my research, people which pull the battery during boot have a dead/bricked or whatever, emmc. Your first bet is the unbrickable mod if u have the soldering skills and the proper tools, after u apply the mod and u can't flash the phone ur emmc crapped and u need to replace it with a new one, u will need an smd station to remove the chip and solder the new one.
The cost of the operation is around 100$, another option is to try and find a new motherboard from a user / broken whatever nexus still at the price range of 100$++
My opinion ? ur phone is dead blame samsung for this **** and go buy a new one without samsung parts ....

Same situation, my battery fell out in my nexus-s phone the other day, and in my son nexus-s phone a few weeks ago. Now I have two dead nexus-s phone. WTF. Has anyone solved this issue or is the emmc mod the only option ? I've read about jtag etc. Has anyone tried that ?

If ur battery fell during the boot sequence then ur emmc is bricked, and u need to replace it ther is no mod to fix this nor jtag can fix it, if u have experience with smd soldering desoldering reballing reflowing etc etc then u can fix it urself
The cost for this will run around 100euros depends on the shop and the method that they will use to solder the new chip
You can ask local technicians how much they charge for something like this, my opinion is that if they want more than 50euros ur better off buying a newer phone

actually the battery fell out during the shutdown. Does that change the diagnosis ?

no cause ur phone acts completely dead 99% when a nexus s can't give a signal of life (despite battery heating when u plug the charger) it's an emmc brick which can be resolved only if u replace the actual chip all the emmc bricks happen when the battery is removed during boot / shutdown and rarely when the phone is already running android
But if u want to be 100% sure the only cheap solution IF U HAVE THE EXPERIENCE is to perform the unbrickable mod, which requires to remove a resistor on the motherboard and bridge 2 pads, then ur phone will be detected and if u can't flash a rom in this stage then u need to replace the emmc
As for me i'm sure that ur phone has an emmc brick, a nexus s that acts dead, no vibration, no lights, no nothing, except heating when u plug the charger indicates a hardware failure
You have 2 solutions bring it to a shop or fix it urself if u can ... nothing can be done with software at this point that's my opinion

Q: dead or still alive?

Hi all experts.
I have one inquiry about my Samsung galaxy S II lte (SGH-1727) Issue.
at the beginning I read too much here but I couldn't find any answer for my phone problem.
the problem happened yesterday, when I was using my phone as usual then suddenly restarted, this issue happen many times before and its ok for me, it tried to restart but suddenly stopped( black screen), I removed the battery then I tried to restart it again, I felt the vibrating start, then stopped, without any respond at all till now, I tried many times to remove the battery and restart it but without any respond, I connected it by using the usb cable, but nothing, ( no vibration, no battery charging) the only thing is my computer can`t recognize the hardware.
I tried to do hard reset or anything, but without any respond.
Kindly, I want to know weather if this phone is totally spoiled or there is something I can do for it to make it usable again, I have a good knowledge about WM5,6,6.1,6.5. but a little bit about android.
thanks

could be bad battery and/or battery contacts.

I have been read the button problems for sure, but I think it is not related to the button, there is no respond at all, even not charging, usually if I use the charger, it should start charging, correct me if I`m wrong.
the battery was full and working fine, I tried to clean the connectors too, nothing changed.

could be a bad cable, bad battery, bad phone port, or hw failure.
id keep trying to revive it by either changing cable/charger and/or battery and keeping it plugged in for a long time, if all else fails then it probably a bad mobo or memory, happened to my sons s2 where his was getting hot while recharging and his phone died, no response of any kind, under warranty i think they replaced his mobo

if battery is removed and phone is plugged in it should vibrate, mine does, seems as if yours does not have any life so mobo would be my first guess.
and yes battery could just up and die, but would give some symptoms b4 hand

Trullty Dead?
so i have spent lots of time looking for this issue with my Hercules. i had beeb trying some roms and i think i bricked it, bad,
so odin can see it (gets a yellow) but;
i can not power on the device, get it into recovery OR download mode,
my pc cant get to the information on the phone (i have tried with SD in/ out SIM in /out)
the pc makes the noise when i cycle thru power, but the screen shows nothing,
i have installed Kies but it dosent see the device,
there hasnt been a good post that comfirms that my phone is now a paper weight,
but there has to be a way other than spending $40 to have it repaired (not including shipping)
USB JIG looks interesting but i cant see how that will help in this case...
to be honest this is my first time at ROMing around with a Galaxy,
previously i had an Gooapple 3G and was able to ROM around quite abit no issues with a bad brick like this i was able to save it before
but if anyone has any ideas or can confirm its a hardbrick let me know i only have a few hours between jobs to fix it and cant at night gf takes laptop to night shifts.
thanks for your time reading over if you have questions about anything please ask, i payed for the phone outright to put on Rogers so there is no warrenty anymore and Rogers wont cover repair.

Oh thanks, I just noticed your comment because I thought there is no chance to get my phone alive again, I think I should try this, I have one question regarding the usb jig, is there a specific JIG for every samsung galaxy model? or it is all the same for the micro USB Samsung galaxy phones? and in this case, what is the indication that will make the device run again, is there a special software to install? or after plug this JIG I can be in the bootloader? and is there any possibility to get some of my data or contacts again? thanks for your respond regarding my phone issue.

Jigs don't with on this device. Don't waste your time.
You need to try to odin the stock firmware.

This is incorrect. Jigs do in fact work. However most of the time you will be able to enter download mode without one.
I have had my skyrocket completely unresponsive to any input/button combinations. I tried my homemade jig and was able to recover via Odin. Without the jig my skyrocket would not have been repaired.

hi toyes
just a question regarding your experience regarding this issue, do you mean it was totally unresponsive? not even yellow sign? not even vibrate by connecting the USB cable? and regarding USB JIG, is it the same with 301k resistance? or there is some modifications?
thanks a lot.

Read starting at post 6435 for the next page or so...
Basically I had zero response from the phone. Was playing around with the jig and buttons, put the phone down with the jig in it. Looked back 5 mins later and it was in download mode.
I do think there is something different with my device though. Ever since I got it back from JTAG it has never wanted to reboot. Selecting reboot just shuts the phone down. Every once in awhile it reboots from recovery ok, but that is about 1 in every 10 attempts. When it doesn't reboot I need to long-press the power for about 30s - 1m to get it to fire back up. I am thinking it is some type of hardware issue but not too concerned because at this point it is still 'working'.

Dead Nexus 5?

I just got this very neatly used 32GB Nexus 5 and on arrival yesterday afternoon it worked well except for the reboot problem the seller indicated. I flashed stock all over and rooted and installed ElementalX kernel for tap to wake and everything was going well, until last night when it just up and died on me. I thought maybe the battery was drained and I plugged it on the charger. It wasn't charging so I left it overnight. On waking up the phone is still dead. Doesn't charge, doesn't boot, nothing. I've opened it up, disassembled it to check all the parts, and everything looks fine. I also tested the battery by touching the tip of my tongue to the connector and I got the normal tingy feeling indicating the battery still has juice in it. I also checked the two LDIs and they are all still white; no water damage. I'm just at my wit's end now and considering getting another motherboard if that would fix it, but I just want to ask if there is any hope through any kind of fix before I commit to getting a new motherboard.

It might be that ?

Thanks for your response but my phone is not even booting up at all. It's just dead. Not booting, not charging, nothing. Thanks again.

IF you press power and the volume buttons and connect it to computer, did you have in device manager something?
If it was something like QHSUSB ... you can try that (it use and LG debuging software who reflash the nexus all at stock like in the factory) : http://forum.xda-developers.com/goo...-unbrick-nexus-5-stucked-qualcomm-hs-t3043301
If not it was possible that the EMMC is dead
I hope i have help you

I tried that but nothing comes up in Device Manager at all. The computer does not detect the phone in any way at all too. I think the motherboard is dead. I ordered another working Nexus 5 with a broken screen on ebay to use and swap out the motherboard.
Thanks for your replies. I appreciate it.

s7 hard bricked (qualcomm version)

Hi,
I flashed a rom that did something bad to my phone. After reboot it just stays black without any response at all.
I've tried all the key combinations and just tried the USB Jig (confirmed the jig worked on my S3) but nothing.
Is there any way to get into download mode?
I've heard about JTAG, but not sure if that will work.

First, try to connect the phone to your charger to see if any LED lights up, if this doesn't happen, try connecting the phone to your PC and see if ODIN detects the device, if that also doesn't work...the best course of action would be to send it in for repair, although chances are you've hardbricked it.

Thanks but I tried that already, pc doesn't even see the phone. Also charging gives no response.

Possible it is stuck in some sort of loop, without having any LED to indicate it would be impossible to know
The charger doing nothing seems strange though
If you had an LED showing I'd suggest waiting for the battery to drain then trying to enter download mode again, but I guess if you've tried everything else and are considering opening it anyway for a JTAG, then disconnect the battery first, see if you can get back in after reconnecting it

Yea tried all that but no luck.
I will try for the JTAG, but need a heater I doubt a hairdryer will be enough to pull the back off.
Also need the JTAG machine itself

opened the phone and removed battery but still nothing, it seems JTAG is the only way.
anyone knows how that works?

Are you getting some sort of output?
I'm using the Exynos variant, I've yet to encounter anything that wasn't solved by holding power+vol down+home for 40-50 seconds (it'll boot to download mode eventually usually)

Tried for one minute and no result.
No output at all, nothing gets recognised in windows. No LED, no nothing...

Well, some users also reported sudden blackout with no response at all, it turns out it was an emmc failure. He then proceeds to send in his phone and luckily, it was replaced. Your mileage may vary, you could try playing "dumb" with Samsung. After all, with the phone dead there's no solid way to tell if KNOX was tripped.
