I've seen an increase in people who have gotten themselves stuck in a bootloop or can't seem to get the combo right to get into download or recovery mode.
Assumptions:
You have the proper drivers installed
Samsung Driver
Your phone is recognized by your PC
Instructions:
Power Phone off
Extract this folder to your computer
Run batch file for Download or Recovery Mode (it waits to see your phone)
Plug phone into computer
Power phone on
Phone should be detected and go into the proper mode
Thx Red_81, again. Glad to see u put this here for the i777. Appreciate u sharing this. It should provide some good help for many users. :thumbup:

So much easier than trying to explain how to install the sdk and then what commands to run. The only problem is you need to have working drivers.

My phone is stuck in boot logo. Computer is detecting phone as "SAMSUNG Android ADB Interface" but adb is not recognizing my phone.
Any ideas?

Never mind. I just got it working.
Had to just enter adb command directly. wait-for-device is not working for my phone for some reason.
If you get stuck there again, unplug and plug in the device again.

Thanks
Thanks i was tinkering with a noria 7" tablet, which hasn't worked right since i got it but for 65 bucks its to be expected, but i used sdk manager to get it to register on my computer as an android adb device and for some reason i tried to turn the wifi on and it crashed and got stuck in a boot loop idk why. like i said hasn't worked right since i bought it. But i did use adb portable like you said to get into recovery mode and it worked great thanks! For other noria users when i figure out how to flash a rom to it i'll start a section here on xda as soon as i figure it out. Thanks again
Any suggestions if ADB doesn't see it?
- Phone was working fine in the morning and at lunch I noticed it was off.
- Try to turn phone back on and it is stuck at the samsung menu like everyone else.
- Soft and hard reset change nothing.
- Neither recovery nor download mode works using every key combo that I've seen suggested.
- Computer detects a device but "USB Device not recognized" and ADB can't see any devices (and I know it is set up correctly as I have the full SDK installed and known to be working).
- Charging still works fine and the battery is now at 100%
- Phone is NOT rooted and has no special apps or any recent changes to change the situation (not even app updates since a few weeks)
I'm not sure what else to do. I will probably let it sit for a few days without a battery, but otherwise I would open it up and see if there is some mechanical/electrical issue like a short or something somewhere. Pretty sure this is a software issue though. Any ideas?

To use ADB you must have USB debugging enabled in settings under Developer Options. If you don't keep this enabled all the time, and it wasn't set when the phone stopped working, then ADB is not an option.
Hopefully, you can get into download mode. For reference, here are the ways I know of, in case you haven't tried something here:
If you can get into download mode, you should flash the stock firmware and then perform a wipe data/factory reset from within stock recovery.
There are several ways to put the phone into download mode. You should try all of them that you can before you give up.
Recovery mode:
With the phone off (and not connected to the computer), and battery installed, hold all three buttons, vol- vol+ pwr continuously until the initial boot screen appears the second time.
Download mode:
1. With the phone off and connected to the computer via USB cable, and battery installed, hold all three buttons, vol- vol+ pwr.
2. With the phone off and battery installed, hold vol- and vol+ (but not pwr) while plugging in the USB cable.
3. With the phone off and battery installed, hold vol- (but not vol+ or pwr) while plugging in the USB cable.
4. Attempt each of the above three options with the battery removed from the phone. The computer will supply the power to the phone.
5. Use Android Debug Bridge (adb) which will only work if USB debugging has been already turned on in Developer Options, since you can't boot into the system to turn it on. With the battery installed and the phone connected to the pc via USB cable, use the command "adb reboot download".
6. Use a USB jig. With the battery installed insert the USB jig into the USB connector of the phone. Some have reported that this method works when no other method would work.

Thanks a ton for the reply. Recovery mode does not work but using your methods I AM able to get it to boot to download mode. If it matters, USB debugging was and should still be enabled.
Now the question is... is there any way to backup the phone from this state or get into a state where I could back it up? I don't really care about my pictures or anything else as those were recently backed up but some app settings would be nice to save (Clash of Clans village without Google+, ugh). I'm going to do more research on the next step myself but if you have any suggestions or information to point me in the right direction I would of course appreciate that as well. Thanks for getting me this far though!

It's pretty difficult to recover information from the data partition when the phone is in a state such as you describe. Maybe the developers and technogeeks can do it. I can't. However, depending on where the game saves it's game data, you may be fine. If the game data is saved to the USB memory (internal sd card) then it will still be there once you flash new firmware. Your pictures should also be fine, since they are on the sdcard.
Hello Everyone,
2 days ago i tried to hard reset my Karbonn A21 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 nothing happened 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. now whenever i connect my phone to the laptop, i get Qualcomm HS-USB QDloader 9008(COM 4) in ports section of my device manager. 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...

Hi there,
yesterday I tried to root my new Tablet Z (16GB, LTE, Model: SGP321, Firmware: 10.4.B.0.569) and it doesn't start since then.
I used an ubuntu live CD for all these tasks because fastboot doesn't work on my win 8.1 and my debian wheezy didn't have the libc-dev needed in its repositories (didn't want to mess with packets that weren't yet integrated into my OS).
What I did:
unlock the bootloader according to http://unlockbootloader.sonymobile.com/instructions
I followed the instructions here: http://forum.xda-developers.com/xperia-z/general/how-to-root-10-4-b-0-569-t2590781
a few annotations to this:
the firmware rar didn't include a "Recover.zip", so I used the boot.img directly inside the firmware rar
although sony and this CM tutorial use the "-i" parameter of fastboot, I didn't use it because it wasn't used by the tutorial
after I did the "fastboot reboot" step, the device wasn't listed anymore when typing "fastboot devices", which, I think, is okay since the device should restart then.
I think it didn't really restart, because the LED on the side glew red.
I tried to turn on the tablet but it didn't do anything (the LED kept glowing red).
I tried holding vol up and power for a few seconds (until the LED blinked first once and then three times) but the tablet wouldn't do anything except for the LED glowing red. at somepoint, the LED would turn off (I think that happened when I hold vol up and power for more than 10 sec).
I was able to let it glow red again by pressing vol up and power again and release the vol up button before the power button.
I also tried to use the PC companion on my windows machine to repair the tablet but the tablet wasn't even recognized (either using the fastboot-procedure by holding vol up while connecting the tablet nor normal plugging in...)
any ideas what I could do next?
Same Problem!
Hey wullxz!
I have the same problem. Red LED most of the time, and I cannot make ANY USB connection to the PC. The tablet won't show up in the device manager. So obviously cant use flashtool, nor PC companion. Ive tried all this volume up and down button stuff, but simply cannot get it to show up on the computer.. Tried a different USB cable as well.. Same issue. The USB port is definitely not broken. Its brand new..
Have you found any solution ? Or anyone else? Mine just got back from Sony Repair.. they wont fix it cuz they detected that Ive tampered with the original software.... meaning Warranty Lost!
Great!
hi,
i also sent mine to sony for a repair. i wrote that i did a firmware update and the tablet wouldn't boot afterwards.
i didn't try the bootloader-unlock again afterwards.
Help Needed!
Tablet Z with unlocked bootloader and rooted 10.1.C.0.370
My issues occured after a downgrade to 4.1.2.
I CAN:
1) Start my tablet, everything normal...
2) Charge my tablet
3) Go into safe mode
4) Go into fastboot mode (solid BLUE LED)
5) Use the memory card and use root apps (maybe this could help restore?)
I CAN NOT:
1) Get my PC to recognize that a USB device is connected. Neither in Mass Storage mode, Media mode, nor fastboot mode.
- Tried with several cables and computers (this is not a driver issue, since it won't show up at all in device manager)
- Flashtool obvious;y says, no device connected
2) Get in to flashmode: device blinks red for about half a second, then green for half a second, and then LED is off. Nothing recognized via USB on PC
3) Get into recovery mode
4) Update over WIFI (fails because unlocled bootloader I suppose)
Any help would be greatly appreciated!
i think you should open a new thread for your problem because it seems like it's not really similar to my issue.
you should get more/better replies in an own thread.

let it charge to 100%, check for flashmode drivers installed and then try attaching it to pc only when flashtool asks you to do it.

Hey thanks for your reply... It wont go into flashmode... Theres something fundamentally wrong.. I cant figure out what... I leave it plugged in for 48 hours..but it doesnt really get full.. the most Ill get the orange LED.. like 50%... now its on since about 12 hours.. no LED on at all... strange..
But yea.. no flashmode... Nothing showing up when connecting the USB cable... nothing in device manager..and therefore flashtool sees nothing!
SOLVED
Problem solved! I can't believe it. Two bad(?) USB cables. Bought a new one, charges fine, flashmode fine. Flashed stock ROM.
However the Camera still doesn't work. Maybe the problem of the cable inside which may have come loose!
Hi, I was looking everywhere since yesterday but can't find a solution. I had cwm + twpr + lollipop cm12. I've decided to back to stock, so as allways: driver, b2cApp, kdz, v20h and v10a, usb, s/w mode, xml parser, shhtp, etc... Standard offline kdz method. But during flashing I stuck on 15% and get the info that my phone anad pc are not connected by usb cable, I tried changing usb ports at pc, reinstaling everything, but I have still the same error. If that woldn't be much enough I ****ed something up and I think I don't have any recovery right now
I can put my phone in s/w mode but I stuck on 15% with usb not connected error.
I can put my phone in fastboot mode but my pc does not recognize it, its just pluging in and out it from windows.
I can put my phone in stuck on LG logo 'mode'
Any help? How to unbrick it? How to flash stock or at least some custom recovery? Of course unlocked bootloader. Please help me :crying:
Key it ****ed up even more.
When kdz show me to connect my cable i clicked retry, plugen cable out and in, kdz found my device, and go to step 2. In half way I had again the same error, so again clicked retry, plug out, plug in. Again founded my device, when I had downloaded 100%, same situation. founded my device, log that tool is extracting kdz and nothing. Waiting about ~1,5h, nothing happend, so I diconected cable. In that moment kdz go to third step and I get windows force close for not repodnig app kdz. I said a loud **** and started again. Phone has not been found anymore by kdz. After a few tries, booted to fastboot, and connected to computer. It has been found as Google Fasbtoo USB, no way to update driver to fastboot. I disconected phone and decided to try again with s/w but nope. S/W not turning on anymore (with or without battery). Fastboot not turning on any more. Just LG logo, when I'm connecting device to PC it is sometging pluging in and out but nothing showing in device manager
Any ideas? Please!

Hi guys, I recently purchased a Homtom HT3 for my mother, when it arrived to me I charged it and checked it out a bit just to make sure everything was fine which it was.
She collected it from me the next day and told me she'd start to use it the day after, she calls me up the next day and tells me there's some problems with it and a few people at her workplace tried to fix it for her to no avail. I pick the phone back up and I notice that everytime I power it on, it gets stuck on the "homtom" logo.
As I don't know too much about fixing phones I only took the following steps before asking for advice here; I went into recovery mode by holding up volume and power button, the android guy with the red triangle appeared so I tapped up + power button to get into the recovery(?) menu. I wiped the phone to factory settings and deleted the cache in there but it hasn't fixed the problem.
I assume I need to flash a firmware or something to potentially fix this, but I'm unable to find an official firmware from doogee/homtom's site for the HT3. I've found a firmware that I downloaded from "chinagadgetsreviews" but I'm a bit weary to try and flash with that rom because it isn't from the manufacturer. (even if I knew how to - the only experience I have is rooting my own phone but that's when I actually had access to a working phone, not one thats stuck on a boot logo).
Sorry for the long post but could anyone guide me in the right direction here? TIA
I'm not opposed to not using official firmware, I think I use cyanogen mod(?) on my own phone. I'd just like the problem fixed in the easiest way possible.
Trying to fix it myself by flashing a rom via SP flash tools but I've ran into another problem which is stopping any kind of progress - the phone isn't detected in Windows, I can't enable usb debugging because I can't get passed the boot loop, I've tried installing the ADB driver manually which didn't seem to work (just said it didn't install correctly and left me with a yellow exclamation mark) and I tried to install it automatically via ADB driver installer but it just throws up an error that the device isn't detected.
Any help would be greatly appreciated.
Hello. I bought a Homtom HT3 and next day a done an update with sp flash tool. all gone ok, but phone now wont to turn on. I contact homtom and got all drivers and room to fix it.
