Recently I flashed ROM. Both IMEI were invalid. So I flashed recovery.img file also. Now I can't even access the Recovery Mode by hard reset. When I connect it to Pc via USB, it recognige it for 2-3 seconds with connect sound, then with disconnect sound. With thoese 2-3 second it shows COM port in Device Manager. So I can't do any thing to connect it to PC or Power it on. I have NO BACKUP also.

After try everything you can thing about this finnaly work!
You will need ODIN 4.38, some random full package ROM
1.Remove your SIM and Memory card
2.Load ODIN in your PC, and load the ROM files
3.Connect your Phone whit the PC via data cable and enter Download mode (Volume -; Home Button; Power Button)
note: if don't work, try another USB slot, my phone don't accept back USB's and i succed to connecting to front one!
4.Now ODIN should found your phone
5.After ODIN found your phone, disconnect the phone and reset him. It must work now
Cheers Sorry from my eniglish, hate to correct
Hi!
I had my device connected to PC in SD transfer mode to load a file at the SD card and restarted the device afterwards to reboot in recovery mode. Unfortunately I forgot to set it back to normal USB connect before restarting and restarted it, still connected to the PC in transfer mode. Since that, my device won't boot at all. Neither to OS, nor in recovery mode. It seems to be stuck at the data transfer mode. My pc recognizes something plugging in (USB connection sound) but i can't access it. Even fastboot doesn't recognize any attached devices.
Before that it worked fine several weeks, problems with a failed flashing or OS-problems are unlikely. I also tried another phone battery to make sure, it's not just the power supply.
Is there a simple way to fix it? I have no problem to lose all data (since it's just a testing device with nothing on it) but without access to the device i don't know what to do.
Device Information:
rooted HTC Sensation with CM 13 (customized for HTC Sensation) with TWRP recovery.
Hey guys,
I tried to root my SM-G930F and I probably have used the wrong ROM.
When I turn it on I got the following message:
"An error has occurred while updating the device software. Use the emergency recovery function in the smart switch PC software.".
Problem:
Phone will turn on just if it is connected to the charger/PC. (Otherwise the screen will be always dead black).**
**If connected to PC it will power off in 30 seconds or less.
OBS:
1. Phone NEVER turn off while connected to the CHARGER.
2. If connected to the PC it will turn off after 30 seconds, no matter if I'm in the message screen or in download mode.
Already:
3. Tried several cables (Including stock cable).
4. Tried to charge the phone.
5. Tried to remove SD card and SIM card.
6. Tried other USB ports and a USB Hub with external power source.
Any help would be great!
Thanks for reading and have a great day.
Did you tried to flash fast in odin stock image ? Did you tried with other charger ?
Hi,
maybe one of the experts can help...
I have a LEMAX2 with X820_20S_ROW_CUOCO92 ROM.
Since half a year or so the USB-Connection to the PC does not work anymore. Tried several cables and several PCs, no change.
I can boot the phone in RECOVRY Mode, but it It shuts itself off immediately.
I can enter fastboot mode, but the phone is still not recognized by the PC.
When I connect the phone via MyPhoneExplorerClient, WLAN works, but MyPhoneExplorerClient says 'USB-Cabel 'Not conneced.'
When I unplug and re-plug the USB-Cable, for a short time MyPhoneExplorerClient says 'USB-Cabel 'conneced', but no setting option for USB configuration can be found and after a second or so MyPhoneExplorerClient shows 'USB-Cabel Not conneced' again.
I tried to find out how to change or repair the firmware but all howtos require a USB Connection.
Mayby I accidentaly removed some system software responsible for the USB Connection?
Any idea?

Good morning guys,I've been trying since Friday,unlock the bootloader from my phone.
my computer normally recognizes the phone when it is connected, but when I start the phone in fastboot mode, my pc simply disconnects the phone, the USB input is firm, not this badly connects, but even so it disconnects.
I have tried to install numerous drivers times always and the same thing,from the moment it goes into mode of fastboot, it disconnects from computer.
(Remarks: My phone has a mediatek processor, my USB debugging is already activated.)

Click to expand...
Click to collapse
if I remember well,in the debug options I put only for file transfer , this may be causing some problem?
