Hard problems with Samsung Galaxy S6 (broken flash chip?) - General Questions and Answers

Hello guys, I'm really STUCK with the galaxy S6 (G920F) at the moment.
A friend gave it to me he said it suddenly turned off while he was playing a game and couldn't boot anymore.
I can't turn it off, it will keep on turning on automatically.
I can't go into recovery mode.
I can only go into download mode and flash a firmware with odin
I flashed the stock firmware with the latest odin and it flashed successfully. But it's still stuck on the Samsung logo (powered by Android) and won't boot into recovery or do anything at all.
So I read it could be the battery, so I bought a new one and replaced the battery.
But the problem remains. On Windows 7 x64 it's detected as "Gadget Serial" and "SAMSUNG Mobile USB CDC Composite Device" when I'm in download mode.
Odin detects the phone fine.
I then tried using Samsung Kies, and Samsung Smart Switch. Samsung Smart Switch detects an "unsupported device" and Samsung Kies doesn't detect anything at all and is stuck at "connecting...".
I don't have any ideas anymore and I fear it's a dead flash chip or any other board malfunctions.
Any suggestions maybe? Pleasee?

Sounds to me like it has run out of storage space and has no room to cache files when it boots.
Have you tried extracting the stock recovery.img from the stock firmware file then converting the recovery.img to a .tar.md5 file, then flashing the recovery and try to boot directly to it after flashing? If you can get into recovery, you can factory reset the device and wipe the cache partition. Sometimes this solves a bootloop issue after flashing stock firmware.
You can also try flashing a copy of TWRP for your device and then use TWRP to factory reset and wipe the device.

Stuck on boot screen??

im stuck on the samsung galaxy s 19000 boot screen and i can go into download mode but not into recovery... but the problem is that i cant get my phone to connect to computer thru kies or anything and i tried using another cable and computer...can anybody help me plaese??
Did you install the drivers for your phone on the computer? I was in a similar situation with a Samsung fascinate. I got stuck on a boot/flash loop. What I did was look for the phones drivers, installed them on the computer, get it into download mode (with the android shoveling), looked for the Odin software, looked for the fascinates factory rom, and flashed it through Odin.

[Q] bricked samsung galaxy 5830m not detected by pc

I flashed my phone with cm10 I think? every thing went fine with that it was successful, however when the phone rebooted it stops at the samsung logo. The unit will not go into recovery mode. When I put it into download mode the screen shows odin d/l mode and the model is 5830i but my model is 5830m. also the computer does not even detect my device. where do I go from here?
Download a ROM for the 5830m with an Odin install. Go into download and install the ROM with Odin.
pc does acknolwedge that a device is connected
pc does acknowledge that a device is connected, it's as the pc doesn't know that a device is connected,( yes I loaded samsung drivers and Kies). What am I doing wrong?

how to bring back p3100 (solved)

I usually keep flashing ROMS.
This time in sheer confidence I didnt charge the battery full.
I was switching from mokee 4.4 to CM11.
I wiped everything for a fresh install and unfortunately CM11 didnt install.
The tab restarted and now it wont go into recovery. what just happened?
It is just showing logo and I cannot get into Odin more either.
The tab had about 30% battery when it shut off and I cannot reach a charger for it for the next 4 hours.
Can I switch it off in any way to save battery?
the phone has switched off now. Is service center the only alternative? the tab was rooted with mokee installed.

Try charging it when you have time and then try re flashing the stock Rom before taking it to service center
will the tab 2 charge without a recovery or ROM in place?

I think it should
Ok, the tab2 is charging. thank you
I installed all the necessary drivers and odin and recovery on my laptop.
The tab2 is giving error on pc (this device wont start) mtp uSB. THe tab is stuck at 'samsung p3100' logo.
If it is any help, I have a working p3100 also running on stock firmware.
what should be my next step? I think I can manage if only I can get odin to recognize my phone or get into recovery (both of which seem to be missing.)

Try reinstalling drivers
@shsagnik : Thank you very much for helping out.
I got installed all drivers by using the other P3100. But when I connect the bricked p3100, pc doesnt install MTP USB drivers. Under device manager it says " failed to start".
ODIN doesn't recognize it. either.
My mistake was I flashed everything on the phone including the internal memory.
PS: Can I force ODIN to recognize my phone?
Ok, my almost bricked device is back and runnning.
This might just help somebody. but my android handset was on a logo only mode. something in the combination of
Attaching it to pc (windows 7 64-bit)
re-installing and rejigging drivers
trying to let ODIN identiify
connecting via Samsung kies (I also tried restore on kies).
connecting a working android phone instead of the dead phone with pc to find and install drivers.
worked.
PS: I also let it sit dead powered off (worked only when charger was attached) for a whole day before trying to boot into recovery or bootlaoder (both worked).

bricked s6?

Hello, a friend of mine brought me probably bricked sm G920F (galaxy s6). he was on custom rom and twrp 3.0.2. He accidentaly wipped everything on the device and now it is stacked on twrp loading screen. i downloaded usb drivers and odin to flash back to stock but the pc is not recognizing my device when i boot into download mode. So i am a bit stacked since twrp is not loading and the phone is not recognized by my pc. We tried on different pcs with different cables and usb ports but still the phone is not get recognized.
Any suggestions?
hey, I'm in a similar boat.. been wrangling with it for a few days I am attempting the Emergency Software Recovery using Samsung Smart Switch, have you tried that?
It's shown when inquiry adb devices?
You must flash original firmware with ODIN

It has never been rooted or had installed something like a custom rom. It's 100% stock / stuck..
Any suggestions maybe? Pleasee?
