Death of g930f. Red writing in bootload. Wont boot

[mattharper228]

So yesterday my g930f uk version, died and i have no hope in getting it back up and running... Kinda hoping someone here can help me...

All that happens is its stuck on a bootload screen and i cant get no further. I can hard reset but thats it. No recovery and no download mode.

Any help at all would be appreciated

Update:
Well my battery finally ran out. I put it on charge for 10 mins and turned it on and there was life. Booted straight up to home screen. Using the phone right now to write this.

Ran without sd card and sim and no freezing or crashes.

Powered down, put sim card and sd card in and it crashes.

Took sd card out and it's running fine now !!!!!
So must be something to do with the sd card, which works fine in my s4 and laptop

How did it die though? What were you doing with it when it happened? Did you flash anything? We need more details.

Try USB JIGG METHOD for download mode

All started 5 days ago.
Day 1, working as normal then Facebook froze on a video, sound frozen on. Phone unresponsive. Forced restart, stuck on boot load loop couple of times and started normally. Normal operation rest of day.

Day 2, froze while on home screen, wouldn't boot back up, stuck on boot loop. Got into standard recovery mode, cleared cache and factory reset, had to do this a few times till finally back up and running normally.

Day 3, same as day 2. Plugged in to smart switch and went on to emergency/reinitialisation and re flashed firmware. Stuck on boot loop, cleared cache and factory reset. Back working after a few times.

Day 4 same as day 3

Day 5, downloaded evr firmware version and used odin (debug mode on and oem unlock turned off) flashed OK but still kept crashing and freezing as before.
So btu rom this time. All went OK, same problems as before, force reboot a few times and loading up to home screen before freezing again after 1 min of use. Then 4th time round that red writing came on boot loader.

I can force boot but withing half a second that writing comes back up. Can't get into recovery mode or download. No samsung logos come up. I can't turn the device off either.

All firmware was the latest version from Samsung server btu/evr/xeu. (Xeu being original firmware)
Btu and evr didn't have WiFi calling in the phone settings so wasn't going to keep them anyway.

Sounds like a defective unit, do you have warranty? If so, just send it in and let Samsung have a look at it

Yeah I was thinking about doing that. I've had the device since release (pre ordered) so 2 and a half months it was fine. There was no OTA update 5 days ago. So that's what I couldn't understand.

However if I return it and it doesn't have the correct firmware on (being xeu, and I have btu on it at the moment) and they figure out ive changed firmware then it would be warranty void job.

The pc still discovers the device in that re writing mode but it won't let me flash anything to it.

Tell us more about the SD card.

Is it partitioned? how long have you had it? does it work correctly with a laptop? have you attempted to clean the file systems in use? are many of your apps installed on it? etc etc otherwise its very difficult to say, could be anything from one app messing things up to a card that is totally frozen and needs throwing.

I've had one where it all looked good but write changes were not persistent (i.e. it was buggered) at least I could rescue the data

Having said that I have had a great many samsung phones and I have never seen the types of screen shot above.....

I'm going to take all the data off it tonight and format the sd card.
I bought about 3 months ago from tesco, it's a San disk ultra 32gb.

I'll update later on, as far as I know, I don't have many apps stored on it, it's mainly just for music, pictures, videos and backup of sms/contacts/etc.

probably worth running chkdsk / scandisk on it first.... might be as simple as a file system error.

if you're unsure you want chksk f: /f
where f: is the drive letter of the card

If you have regularly filled the drive you might also defrag it etc ... also worth checking the LOST+FOUND folder you probably wont be able to do much with it but it may give you a clue as the fact it's been having issues

Well unfortunately it wasn't the sd card. Phone started freezing last night while not being used and no sd card in.

Either way I checked the sd card. 0 errors on it and 10% fragmented.
I formatted it anyway to make sure there is no android conflicts on there.

So I decided to flash the bootloader, flashed the rom again, and also cp/phone partition data.

This seems to have rectified the crashing for now. I've got 6 hours use out of the device with no crashes so far.
