No more bootloader no more nothing, after rom upgrade s200

Hi All,
I've tried to upgrade the ROM of my QTEK S200.
It got completely stuck!!! I had to remove the battery. Now it stays black. Even a hard-reset does nothing. No bootloader, no white screen, nothing. It's like the device doesn't recognize the battery anymore. Same problem with another battery. When I connect the power supply, the light stays red for 5 seconds and then goes out again. No charging (orange) light.
Does this mean that the device was short-cutted (hardware problem) or can this be fixed with some manipulation?
Anybody an idea how I can fix the hardware (if broken) myself? Can't be to difficult if it just blew a fuse ;-)
Thanks

If the accu not charge, I think he is dead. You need a new one. For flashing new rom, you need a good acco over 50 %. Than you go to bootloader modus and flash a WM5 Rom WM5Rom.

Yep, hes dead alrite, make a good paper weight sorry bro...

not the battery
of course I tried a new battery
same problem

Can you make a downgrade to WM5 ? Ist the battery charged now ?

DC Adapter 4,5 V
I had the same problem.
Remove the battery and connect the pin nr 1 (nearest to the cam) to + and the pin nr 5 to -. I think 3,7 to 5 V is ok. Then bootloader and connect to computer.
Don't blame me if anything goes bad ;-)

how to proceed?
I've tried to do as explained...
I've taken an old charger (5v) and connected the cables (black/white striped to 1 and black to 5). I'm not 100 percent sure about + and -, but normally black is always -, if I'm not mistakin'
What should happen? How should I proceed?
My device does nothing... No light. Power button does nothing, hard reset does nothing.
Does this procedure work with a QTEK S200?
Maybe the charger (old gsm) is too old or broken?
Maybe + is black...
Sooo many options ;-)

Worked on mine S200
Of course You must know if the adapter is working and +/-.
When I connected 1 to + and 5 to - I could operate the mobile as if the battery was mounted and working.
My problem began because the battery isn't charging in bootloader mode.
And I'm still stuck there... Because it's a G4 device flashed with G3 SPL... Anyone got a suggestion how to solve this?

I Did the same thing '''''HELP"""

What you should do
Keep the device on for 2 hours connect it to the electricity.
Install the original rom with the PDA connected like that to the PC, if it does not enter the Rom update continue trying by doing a hard reset with the stylus and pressing the left com button on the left side of the device, then retry the rom install, if it says unable to connect continue trying, using the procedure i explained before, thats what i did when the same stuff happen to me i was without my device working for a month, now i´m using WM6 with the Diamond Rom, so its possible, to do this you just have to keep trying.

my prophet is block and after try of hard reboot is dont turn on.. its not turn on on any way, no detect charger ether ( no red led ) battery was almost full when its go off..
plz help, can i try 1-5 pins solution?

My friend. A few people have tried the pin method and one or two have succeeded. IMHO i would not try it, for fear of frying your phone, yourself or starting a fire.
Take out the battery for a good couple of hours. Take out SIm card and SD card. Put battery back in and try to charge for at least 5 hours, even if the light does not show (might just be LED issue).
Then see if you can start in boot loader, u now how to yes? (keep camera button pressed, soft reset with stylus, then let go of camera button after few sconds). What happens?

pins to power
I've tried connecting the extreme small pins to the (big) cables of the charger but nothing happens over here. The screen stays black.
To All,
Any hints on how to connect these cables to the pins, without the fact that they're constantly coming off the pins and constantly touching other pins?
You try and tell me about your experience ;-)

revive prophet revive ;-)
I was just playing with my qtek when I noticed that after connecting and disconnecting it to the AC for 5 times or so (with red light going on and off for a second), it tries to startup, but drops dead after a fraction of a second. Damned ;-) No chance of going into bootloader.
Almost there ;-))

keep it plugged in for about 5 hours, dont play with it or turn it on lol, give a go unless u have done already and just havent said

Direct Connection to 220v doesn't work
The workaround of connecting the pins directly to the charger doesn't seem to work on a QTEK S200 G4.
Since mine is a G4, I wasn't lucky... I'm left with a cut charger cable.
I'll try to charge it for 5 hours but since no led is going on I don't think this will have any effect.

Listen keep it plug in to the electricity for 12 hours, then try to put it in bootloader mode by pressing the, com button on the left side of the device after you hard reset it, with the stylus after you manage to enter the bootloader mode, you only need to follow the steps described on several posts on the forum.

if nothing works connect the device and try to install the original rom, my device is a g3 so i´m not sure if the g4 works the same way.

How To Unbrick Nexus S? Need Urgent Help.

Dear Geeks,
I need your urgent help/advice. i'm three weeks far to my wedding and have a lot of troubles to handle, of course i need this phone.
let me describe the matter i have.
My nexus s is not booting, not starting, nothing.
what i did?
Last night, power button stopped working. I have experienced this 4-5 months ago. I don't know why, the problem has been solved by itself after few days later. i did nothing at those days. the power button came back. (as to my opinion, this is happening due to software problem) Anyway, i have used the market and installed ''fix power button'' application to use volume buttons for opening the screen.
I slept and when i woke up, i saw that phone needs to be charged but i waited. there was %11 something. i tried to handle the power button, pressed many times on it, thought that it may come back again same as 4-5 months ago it happened.
I removed battery and replaced again. i tried this many times. removed, replaced, used the usb cable via AC charger and phone started but there was no result. power button still was not working.
i thought that if the battery runs out, and then, when i charge the phone, maybe this matter may be solved. (ok this was stupid idea)
phone started to charge. when i plug the usb cable, phone was booting and displaying the google and animation and later it was ok to use.
meanwhile i keep on removing battery and replacing battery while the usb cable connected. but when phone starts to boot, i removed battery and replaced again. phone was ok, it was booting. few times it was booting.
but baaaam.
it is now not starting not booting, nothing.
now, when i replace the battery, phone is getting hot, especially sim-card area. i m removing the battery and connecting the usb. same again phone is getting hot, same sim-card area again.
i have waited enough not to connect the battery or usb charging cable. but no result.
what can i do now? what are your opinions?
my opinions/guess:
-i am using 3500 mah lithium polymere battery. maybe the battery died. i m using that battery more than 1 year, around 15 months. i dont turn off wi-fi so i m charging phone everyday.
- phone crashed during booting. and now the phone is totally brick.(i dont wanna believe this, this phone can be usable, believe me i feel it i think whatever happens, this phone can be usable via software installing or rooting... of course if you dont throw it towards a wall etc.)
by the way, my phone was not rooted. no time to root these days. and of course the phone was not starting.
what is your idea? what happened phone? what should i do?
if you reply, i will be appreciated.
A big advice for people reading this, dont remove the battery when your phone is booting.

I hope someone has a solution, since I have the same probelm...
I searched everything and tried every tool in this forum, but no success...

dude, unfortunately those solutions not working on my device.
when i connect charger and i replace the battery, within seconds phone boots itself without power button. it should be this way. removing and replacing the battery helped me to start to boot.
i sense this case a bit different from that solutions.
i need to try with a different battery. my wife has nexus s also. she is very lucky she has no problems i have experienced so far. i will try with her battery.
i think there is a matter with mainboard.
by the way i forgot to say that i dropped my phone last evening. just after then phone was acting that i'm pressing long onto power button. and power button finally stopped working when i remove the battery.
i think this is happened because of dropping the phone from my belly high.
but the last thing i have done which removing the battery while the phone is booting, i wish, i should not have done. i could use it without the power button.

If you have not rooted your device, you should have you warranty, right? Take the phone back to the carrier, and tell them about your problem. o.o Sorry, I'm of no help, but you're in a horrible situation. Wanted to at least give a little help.

Same exact problem here.
2nd of August - mom's phone turned of and just would not boot or prompt at all. The modem heats up when power is turned on or connected.
Tried
The unbrickable methods (but the computer would not detect the device in any form)
A JTAG - I was able to write the recovery and bootloader - assembled the phone and it just won't boot or prompt
Need to try
Another battery to see if it solves the issue.
Removing the xOM5 resistor and converting to a development S5PC110

Tried another battery - no luck
Did the resistor removal and converted to a dev board - Unbrickable now detects the board!
trying to get the device into fastboot - will update

I had the same problem few months ago. Power button had died. While I was able to boot with remove battery and connect to charger option and I was rooted. But after a week I decided to take the phone to Samsung service center to get the power button replaced. My phone did not have warranty. Samsung took few hours to get the power button replaced and it costed me about $7. I think that's the easiest method. They did not have a stock of I9020 power button, so they fixed a I9023 power button.

Any update? I'm curious to see if you get it working. Had the same happen to my NS a few days ago and would like to see if I can get it going again so I can give it to my stepson.
Sent from my Galaxy Nexus using xda premium

I've given nexus s to samsung service. Actually, power button may be handled by replacing with new one, but with no hope, it will not come back when i read messages about mainboard failure. I will update news whenever it's possible.
we'll see.
I would like to hope it is kind of software matter.
Pls god give my nexus s back, i got extended 3500mah battery.
grrr....

So with the hardware mod - instead of selecting Nexus S -> I tied the Galaxy S in unbrickable - first time I've seen the screen alive! - puts the phone into download mode and I can disconnect from the usb and it stays in download mode! .. when i tried to flash odin I get a "There is no PIT partition" error -> this ofcourse is with re-partition and bootloader update UNCHECKED
When I tried Heimdall it wouldnt let me flash without a pit file. So trying Heimdall 1.1.1 - I get Failed to Access device Error: -3
Any chance some one with an i9020T can do me a huge favor? Use Heimdall 1.3.2 - download your PIT file and upload it here?
reaching for string ends out here :/

The power button had to be replaced. I shorted the connection when ever I had to press the power button during the boot sequence. That's how I fixed mine.

Look up jtag. It's your only option at this point. Unless the phone was purchased under a year ago. So yeah, paperweight for now.

thanks for the help i figured the skyrocket would say sky rocket on it lol so i just jumped into the s2 i777 forum like a noob i feel so dumb but will the jtag thing for sure fix it

Almost nothings for sure but it's a pretty good chance they revive it. mobiletechvideos is who a lot of people have used.

ok what about the usb jig thing has anyone tried that an how much does the jtag fix usaully cost

Spend the extra 20 bucks. lol It might matter or it might not. You don't wanna be the one that finds out it mattered though. lol

I would trust mobile techvideos over anyone on ebay. They have a stellar rep.

Hey there, Today my phone got stuck in a bootloop where the screen was black and there was an intermittent vibration. I couldn't get out of this bootloop at all. I tried getting into recovery mode, download mode, using Odin, holding down power for more than 20 seconds, removing the battery for 10 minutes, etc. Anyway, I figured, there has to be a solution without having to take apart my phone and trying to use JTAG, Geez! ANyway, I decided to try pressing the power and volume buttons in different combinations with and without the battery, and while being connected or disconnected to the PC. OK to make a long story short, here is the combination.
Plug USB into computer ( I used win7) without connecting it to your skyrocket.
Remove the battery from your phone.
Insert the Data cable into your phone without the battery.
Install battery and quickly press both the volume up/down button and the power button repeatedly (about 5-10 times) Basically press and release both sides at the same time over and over again until your skyrocket pops out of a bootloop. It took me only 5 presses.
I'm not saying this will work for everyone, but it worked for me. Due to the fact that this happened on a whim, I can't test it out to make sure the steps are just right. Whoever tries this, take note of the steps.
I hope this helps you guys out. Cheers.

what you have sir is a stuck power button, by repeadetly pressing the power button you momentarily "unstuck" the button, it can stay unstuck like that or it can become "sticky" once again, more info on that in the 1stop sticky

uhhhh, another person who is slightly misinformed. a boot loop doesn't equal JTAG. if your phone turns on AT ALL u should be able to recover it and get it working. JTAG is required for a brick, and like its name implies, a brick is just that. A phone that does absolutely nothing but sit there. No display, no sound, no vibrate, nuthin

Nothing. Happens it don't light up or power on at all. It is not reconized on computer either. It's hard bricked.

Make sure the Battery is charging...

How can I make sure the battery is charging when no lights come on at all? All I do know is I had it plugged in for a while yesterday and it got really warm. But no lights whatsoever. The screen doesn't light up at all neither does the led.

??????

There are no notification lights on the D720, but when you plug it in with a charger, you should see a battery bar on the display.
Other than that, you are probably right about hard-brick.
I, luckily, never had a "brick" on the Nexus S, so someone else with experience may wanna chime in. But Google and YouTube are your friends.
Sorry...

Please help me, i have the same problem

been awhile since any action here. saved mine with JIG method once but this time it won't work ??!(why) , in search of a solution again! -> hardbrick #2 on this device!

You guys can try a USB Jig. If that does not help, I think JTAG is what you need.

Jesus... just to revive this thread (and this concept of hard bricking), I think I just accidentally bricked mine as well.
Here's exactly what I did:
One moment, it was working spectacularly - fully stock, but unlocked. I had just listed it on eBay, too.
So I ran a factory reset on it (from the Settings menu), also "erase USB storage".
Then, after it shut down for the reboot, I pulled the battery.
...
That was it. Now it doesn't turn on for anything whatsoever. No device detected on USB when plugged into PC. Remove, replace battery, hold VolUp+Power, nothing. Plug into power adapter, nothing. Nothing at all.
But the back does get lukewarm after a minute or so, as if it's alive in the head but frozen, unable to start the bootloader.
WTF? I also have 2 more of these Nexus S 4G's, and both of them seem to have Flash storage chips that exhibit the same behavior when their chips are placed in (this) working motherboard. They can't boot. When I try to "hot-flash" it by booting the bootloader then swapping the Flash chips, they can't flash anything (this is probably to be expected). So, if I can get my ONCE-WORKING phone back to life, there's a good chance I can get another working as well (one just has a cracked glass, otherwise working mainboard & peripherals).
It's old, yes, but it's a damn shame to E-waste these things for a stupid software problem like this!

Samsung galaxy s6 completely dead. Will not power on or charge

Hey guys, So i was using my Samsung Galkaxy S6 one day when the screen went dead. Now it will not turn on or charge, I have tried using 3 different chargers and tried to use all of the button combinations to reset it and boot it into all the different modes. I have even tried to just let it charge for half a day but nothing. Does anyone know whats wrong with it, whether i can save it or if i'll have to get a replacement? I have emailed Samsung but they still haven't replied yet. It is running stock android not rooted and when i plug the charger in the device gets warm but will not turn on or show any signs of life

When you plug it into the computer does the computer see it ?
If yes, then your screen may need replacing. If No there maybe a problem on your motherboard.

The computer does not recognise it either. What you said about the motherboard must be the problem then. Do you have any idea how the motherboard could have been damaged and whether it was a hardware failure or my fault?

Easy on the MB replacement! They're the most expensive thing on the phone. Try the USB port/daughter board 1st. About $6 on eBay. After that if no joy- have to swap in a power amplifier. Here's a link how to

Not fun but might be necessary. I'll bet it's not your MB.
