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.

BIG WEIRD Fuze problem PLZ Help

Ok people let me tell you i love my fuze and i have followed all directions to updating my rom and i had a nice new cooked rom and everything was running fine until one day i go and take my phone off the charger and it turns off as if it had no power from the battery so then i try to turn it back on and still nothing :O "Sad FacE" then after staring at my phone for 20 minutes in complete disbeleive i started being creative starting with a soft reset to a hard reset , also take note when i put my phone back on the charger the light that breathes no longer came on, then i got my phone to boot to hard-spl olinox 1.90 and it said no boot image and sat there so then i turn the phone off and did a rom update thru my hard spl after updating the phone went to reset but only turned off and the only thing i can pull up is hard spl. plz help it would be so so so much appreciated and im not slow at computers so u wont have to explain everything to me i do programming but never cooked a rom or delt with this

Sounds like you may have a hardware problem; maybe there was a power surge or something and part of the phone got fried. Just a guess, but sorry, man. Could it have gotten wet somehow?
I guess the other possibility is that the battery is just completely dead. You can get into bootloader without a battery (pull the battery, plug it in, and you'll see). You can even flash, but you can't boot up. Try cleaning the contacts, and make sure they're contacting the battery electrodes. Now that I think about it more, I bet it's just the battery, or it's related to the battery (maybe the usb port is screwed). If this fails, go buy a cheap battery for the phone and try it out. If that doesn't work, just flash the stock rom and then the stock spl and return it for warranty. All isn't lost.

Thnx
ok thank you for you're reply. the battery is good i can flash rom off my micro sd card with out power source to phone also the phone had dropped about a foot from the ground onto carpet the same time i started having this problem im wondering if somethen is loose idk. im figuren if the phone can boot olinex on its own then it is still working as in the screen has full fuction as far as i know all buttons work, as i was looking into this phone im wondering if the thing that stops ur phone from charging and turning on when its over heating might be damaged. there is no warranty so im tryen to look into this as much as possible

GOOD NEWS
Ok I have no idea what was wrong with my phone but i found a htc service manual and disassembled my phone then put it back together and hoped for the best and press the power button and boom wala it came on to the at&t flash logo and problem solved all help was appreciated and i hope to help other peeps out as well and cooking up some roms eventualy

You were more help than AT&T i took my phone into the store and told them my problem and they went straight to the idea of a new phone and i kinda got mad and explain to him i dont want your phones i wanna fix mine and he told me it was bricked and i need to take it to a corperate AT&T n the closest one was about 6 hour drive so i left lol so thanks for ur help

That's i had the same prob. once and after a week of frustration, i noticed my reset button was cocked to one side slightly, after jabbing my styles at it a few time presto my POS started worken again

[Q] Blank screen when turning on phone?

Hi, I'll explain what happened.
My phone recently turned off (the screen kind of fizzled away to black) So I assumed this was the battery running out. When I got home I put it on charge and as I usually do waited a few minutes, then tried to turn on, to charge whilst on, the screen lit up the phone vibrated and the start up tune played, but only a lit up blank screen appeared?
I thought it might need more charging so I removed the batter to turn it off and put on charge again, whilst it was "charging" there was a flashing amber light for about 4 seconds at a time, this never turns steady or green, when just leaving on charge.
After numerous batter removals and replace the phone still does the same thing when turned on, but now with no sound, and still appears if the screen is on but blank and the four soft keys are lit, then if I press the power button or if I leave it, the screen goes off itself until I press the power key again (this same thing that would happen if going to lock screen). All of this happening with a now flashing green light?
I tried to access phone by USB cable and although laptop picks up fact something is plugged into USB, it doesn't appear on HTC sync or memory card doesn't appear.
When trying to hold in volume down and power on it's as if it's going to the right screen but still blank.
Stock rom on phone, S-OFF
Anyone have any ideas, without replacing phone?
Thanks

its seems like your phone has bricked.
1. First try this
2. if step 1 doesnt work, follow this
read step by step. good luck!

Have you tried a new battery? My phone went completely black while charging and it showed no signs of life, no charging light nothing. It was a new battery with about 60Percent charge when I put it on the charger. I noticed like you did, I tired to charge more but not even a light would come on. I happened to have another fully charged battery I kept as a spare. When I put the spare battery in, the phone sprang back to life! I threw the other battery away and have had zero problems since. So I suggest you try a new fully charged battery before you do any thing else. Strange thing was the battery I was using was fine the day before and even had the 60 percent charge when I put it on charger. I'm not sure how it happens but somehow the battery just died on charger. So give a new battery a try and see if it will also help you. If it doesn't, then likely it's failure of your device. But please do try because the exact same thing happened to me and the new fully charged battery fixed the problem! I'm hoping it will also fix it for you! Best of luck! You can get a good battery online for under 20 dollars. I recommend Anker extended battery. I really hope this works for you! Let us know.

I'll try this as a last resort and if not I'll get a new phone, cheers and I'll let you know what if anything works

So I get to the point where I have to ./brickdetect.sh and the phone isn't picked up or recognised, any idea how I can get the laptop to pick up the connection properly?

Sudden Death Z3

Hello all,
For some strange reason my phone died on me friday, the last time i saw it on was while updating.
It wasn't charging at the time so i thought maybe the battery ran out, but when i connected it with the charger my phone wouldn't boot correctly.
My Z3 was in a bootloop, it could still be detected by my pc but i couldn't do anything due the fact it was turning off and on all the time.
I tried to enter recovery mode but it instantly restarted itself...
Pc Companion wasn't detecting my phone so i couldn't use that.
since my phone did get repaired already (my screen broke) i could manually disconnect the battery but that didn't work either, i tried a new battery too but to no succes.
I also tried all the button combinations, the only mode i could enter was fastboot mode (blue led) and it would stay on but still no sign of a normal booting process.
The yellow button near the sdcard slot didn't work either.
When i put my phone to charge at the wallsocket the led stays red and it won't reboot all the time, but after 15 minutes the red led disappears and it seems like the phone isn't charging at all.
Today it got worse, my pc can't detect my phone anymore and the bootloop stopped too, the led stays red when charging (usb and wallsocket) but after some time the led disappears.
I can't enter fastboot mode anymore.. plainly said; nothing works anymore.
Anyone knows how to fix this problem?
Sony doesn't want to repair it for me since i fixed my screen externally so i hope for solution

I had a similar behavior on a Xperia T when my battery was deeply discarged.
There was No way to load the battery inside the phone.
The phone has to start the bootloader or something like a "mini kernel" (dunno how it is called exactly) to start the loading sequence.
If you are under the -normally not reachable- minimum volatge (under normal conditions phone turns off before) there is too less juice to turn on the booloader and start the loading.
In my case I opened the phone put out the battery and charged it directly with a power supply by wire.
For me it worked.
I see you write that you tried other battery was this one full for sure.?
regards

I assume that you know that... but nevertheless
I advise you to be very careful with li-ion batterys the
are very sensitive with charging voltage.
There are some tutorials on youtube but do it on your
own risk I´m not responsible for anything...just saying.
Edit: for safety...I think it would be good to try to load the
li-ion battery only that much that it has enough power
to boot in the loading state...then put the battery back in the
phone and load it the normal way.
I wish you a succsessful charging let me know if it worked.
good luck :fingers-crossed:

Shutting down after startup

Hi,
there are some threads about the bootloop problem, but I couldn't find exactly same problem: some days ago my phone landed into the bootloop. It was a bit spooky with battery charging state, it was jumping for different states - 3%, 99%, 24% after every loop. So I bought a new battery and replaced the old one. Now the phone starts to LG logo (with starting sound), but after 10 seconds I can hear the power-off sound and the phone turns off. It seems to be a "normal" shutdown, not the "reset-bootloop": I hear power-off-sound, LG-power-off-logo and LED is blinking blue for about 10 seconds. After that it repeats infinitely. Also, if I turn the phone off it stays off, but if I put the charger in it, it's starts from itself again and again. Did not tried the hard reset until now. Any ideas, guys?

update: tried hard reset. it's starts until "optimizing apps", if it's done, i can see for a second the "first setup" screen and then it's immediately shutting down. same problem with the old, original battery.
edit: for the first time I saw message "high temperature" on the screen, before it was powered off. But the phone is not even warm...

What you describe is exactly that happened to the Mrs's GF2. One day it was fine and then all of a sudden the battery drained really quick. Now she can only get to the optimizing apps screen before it shuts down again. Ordered a new battery but that doesn't look to be the solution from your findings. :crying:

My phone has the exact same prblm n i was thinking of buying a battery but now that i have read your post i am doubting my battery purchase.
By the way have u found any fix also are u sure the battery is genuine n not some poor replica?

I had this problem when I had flux in my battery port causing a battery connection problem. Sometimes it said temperature too high and other times temperature too low. I was able to fix it by taking out the motherboard using 90% alcohol and a toothbrush to clean the battery port in the motherboard. Then I let it dry and problem was gone. Now I'm not saying this is exactly your problem but it just means that there's most likely bad connectivity to your battery. It could be your battery, the cable or the port.

Mrs received her new battery and it seemed genuine. Put it in and the phone is 100% dead. No power, no charging, no life.
Its not all bad news as she bought a Honor 6X which is a far better phone.

I tried all the hints I could find (except cleaning it with alcohol), but nothing help to start the phone again. Could be defective heat/temp sensor on the motherboard.
Battery was from "Polarcell" - that's a pretty good one manufacturer with satisfied user reviews on amazon (also had good personal experience with their batteries). Just for info: phone doesn't even start with original battery anymore - same problem.
I already switched to Honor 9 (excellent phone!), but will give another try and clean the battery attachment port with alcohol today. Will give you an update later.

If you plug the phone into the charger does it even show the battery charging symbol at all?
From what I've been reading the temp sensor is in the battery and sends the temp signal through the battery connector to the motherboard. So if you replace the battery it's like plugin in a new temp sensor. However if the connector is bad then that's the only thing that I can think off that would prevent the phone from starting. If the port is bad I don't know if it can be fixed or not.

Had no luck yesterday with port cleaning. Still the same error.

Yes, but it's more complicated. If the phone is turned off and you plug USB in, it starts to boot from itself (without pressing the power button). In most cases it's going up to LG logo and powering off again. After powering off I can see battery charging symbol for about 5 seconds, after that it's changing to battery symbol with an thermometer. While the phone is in this bootloop, it's charging. From the point with this battery temperature symbol it stops charging. I read something on reddit about getting it up to 100% could solve the problem. So, I tried to plug it on and off about 50 times to get fully charged, got it up to 100%, but it's still rebooting. Can't get into recovery, but it's possible to get into the "hard reset"-menu, where I can wipe data. After this the phone boots normally (at the first sign), it's starting optimizing apps, I can see the "first-setup"-screen (that one with language chooser) for a half second and it turns off again. Same behavior with both batteries - new one and the original.

That's a lot of combined symptoms. I have no idea what could be wrong with yours exactly. I would try to bake the motherboard with solder flux as a last resort. I had to do that with my G flex 2 twice to bring it back to life. I'm not sure if it would fix it in your case, but at this point you don't have much to lose.

I've already spent enough time with trying get it back to life. Loved this phone, but I had to send it to LG service every half year (3 times!) and got it every time with a new motherboard back. My brother had to send his one two times within a year because of several problems (no vibration, no sound through 3.5 jack...). Furthermore it was not possible to root or unlock the bootloader since Android 6 (what I've got with the last replaced mainboard, but what was not available through the software update!). So, just for me it was a very bad experience and for sure I'll not buy an LG phone for the next 10 years.

Oh, that might void your warranty if you changed battery yourself. As I can see you're from Germany, EU, so you should ask for DAP (defective after purchase) act from service to get refund for your phone.

I've never heard about DAP. Do I give them my phone and get from them some money back or what is that about? Is it an manufacturer service or general refund possibility in EU?

I assume it should be available in EU. You should contact your seller or the service about if for detailed info. When you dave details about that please share them here.
