i tried to hard rest my Karbonna9+ android phone. i pressed Power+volume+home button. after that there was an error displayed on the screen saying "ENTRY QPST DOWNLOAD". i quickly searched on the internet but wasnt able to find any successful link. but then my computer asked me to format the device, i thought this will reset my phone but unfortunately i was totally wrong. after the format i tried to start my phone again but nothing happened. i also tried different combinations of keys but all nothing happens not even a single pixel lit up lol. then i downloaded cherry mobile flare software and AIO flasher and all the image files and other files required. they didnt work for me too coz my laptop (windows 7, 64 bit) doesn't recognise the device (unknown device or Com5 error). i tried to flash it in fastboot in AIO flasher. it says flashing but nothing really happens even after 10-15 minutes. all the online forums i searched they say enable debugging mode on ur phone in order to reboot but i dont know how the heck i can do it when my phone doesnt even start up lol. I am left with a dead phone now. can anyone please help me out and solve my problem. and please advise me step by step what to do next in order to get my phone working please...

Hello Everyone,

Hi,
my friend's Nexus S was stuck in a bootloop. i went into recovery mode and hard reset the phone, so that the phone would come back to stock. however, the phone was being reset when the battery of the phone came off, switching it off.
the phone fails to start. there is no response when i try charging it. Also, it does not go into DOWNLOAD mode or FASTBOOT, so i cant even run any utilities to flash the stock rom back. adb commands as well as the nexus toolkit show that there is no device connected.
can anybody suggest me what to do?? i was gonna try odin but i read somewhere that it is only useful for custom recoveries, not to flash stock roms.
i've gotten some usb drivers mentioned at some thread, saying i would have to update my 'android' device listed in the device manager using them, but i cant seem to find any device mentioned in my device manager either.
any suggestions as to what i should do??

Something like this happened to me a week ago. I have Nexus S 4G. So, I ordered USB Jig from usbjig.com and now I have download mode. It worked! :laugh:
You can buy USB Jig from that site, or build it yourself, or borrow it from someone.
hello,
I hope someone can help me with my AT&T LG Optimus Pro G phone, which I have royally screwed up.
I was experimenting with the cyogen mod and after installation I installed the freegee app and once the cwm recovery was installed, I decided to go into the recovery by holding down up volume and power button.
Once I was in recovery for CWM i couldn't exit out, and the phone constantly booted into recovery after every reboot, even if i took out the battery, and powered it on.
I tried reflashing the cynogen mod through the sd card, and even though I would get success message the phone would still reboot into the cwm recovery.
I started doing research on the internet and i found file exitrecovery.zip that could be used to possibly get the phone out of the cwm recovery.
After installing exitrecovery.zip, I rebooted the phone, and now I have complete black screen. There are no light, no hints the phone is even turning on, and I can't get into recovery( or at least I can't tell). The only thing now is that when i connect the phone to the computer the window tries to install drivers for the device, and eventually prompts to insert a CD for LG drivers. I already have LGUnitedMobileDriver v.3.10.1 connection drivers installed from their website.
Please help, I am really stuck here..... and have no clue what to do. I am fairly new with rooting and modding, and I am extremely miserable.
The phone is still under warranty from LG. Anyone if all else fails, and since the phone has no screen or lights, whether they would replace it?
Attaching the exitrecovery.zip that I used.
sobbing....

hi, thanks for your reply. Again I very much new to the rooting and android OS tinkering, and nowhere close to an experienced user.
I tried to use google with your information in regards to how to use flow ROM with expansion.exe, but did not get any leads.
I would appreciate if you could elaborate more on this process.
When my phone is connect to the computer via usb is is constantly trying to install drivers. I had already installed LG usb connection drivers in the past and it was successful. It almost seems it tries to install driver yet fails after receiving no input from the phone, and then request LG CD with drivers.

Try to find driver on the web-site of producer. Set them. Overload a vehicle in Bootloader. In the controller of devices on компе must be determined your device. Then on a computer start sewing - .EXE.
Did you get this problem resolved? I have the exact problem with the exact phone!!!
thank you very much
Hello community,
i kinda read everything on every forum about this topic, and nothing really worked, so i am asking here now.
I tried to flash CFW on my phone, but since the guy making the thread was a genius, i downloaded the wrong cfw for another handy, bricking my recovery, i am also stuck in a bootloop. HOWEVER i can still access Download mode and Emergency Download mode.
BUT if i connect my phone in download mode to my pc, it says that it is an unknown device, i deleted and installed so many drivers just to make it work, it did not. I also swapped USB ports, cables etc.
Suprisingly, when i connect my phone in Emergency download mode, Windows finds my phone and it actually works, even odin finds the phone, but i still cant flash it since im stuck on "setup connection".
I am on Win 8.1
Any help appreciated
I have a Xperia S running cm 12.1 with unlocked bootloaders TWRP installed and i tried to partition my SD card [http://forum.xda-developers.com/showthread.php?t=2584759] but clearly something went wrong and now the phone wont boot. I made a lot of research and tried everything but all the guides require to be able to boot into flashmode . My phone is dead the only sign of life is a red led when its charging which after some hours of charge will shut off. When the light is off and the phone connected on PC, the PC can recognize the device on unspecified devices (QHSUSB_DLOAD). i have installed all the needed drivers from Sony, google drivers from sdk, and adb drivers(adb wont see the device and i tried everything to do so, but nothing seem to work). I got a market for android on my pc called mobogenie that when i connect the phone it detects that a phone is connected but wont see what phone.The hardware reset buttons work but its useless in the current position. Concluding, the phone is bricked and wont open in fastboot-flashboot-bootloader-TWRP, its recognized as a device but not as "Xperia s" i got all the drivers and i want to flash the original firmware (already downloaded) to fix it. A possible problem is that the partition table is destroyed and after the flash it will hopefully be restored. The problem is not on the hardware but on software. I tried to trigger the download mode with the Samsung way (USB jig, 300k ohm ) but nothing happened as expected. Every solution i found required flash mode which is not accessible at the moment and i tried lots of things to go into fastboot(ever the rubber band trick,remove the battery etc). PLEASE help i dont know what to do, please help me flash it (i already got flashtool, Emma) or anohter solution. Thanks for the help in advance. (its my first thread in the forum, i hope to post it on the right section, i posted it here because i need the assistance of the developers i guess)
Hi,
You've asked in the correct section: http://forum.xda-developers.com/xperia-s/help/how-to-unbrick-xperia-s-lt26i-tried-t3265523/
so I'll close this thread.
