Hi all, new in this forum because i need to ask for help, i ve already read a lot of threads here but i couldnt find a solution. In this moment i cant aford a new phone and this one do all i need, so im trying to save it.
The phone suddenly restarted and get stucked in the LG logo. If i restart it, it stays in LG logo. I ve already tryed to hard reset it, but the same, it stays in LG logo. I cant enter in Emergency mode. The only mode i can enter is Download mode. So ive tryed to flash it with the stock rom, that ive used a couple of weeks ago in this phone when i had a similar problem, but this time didnt worked, it get stuck in 4% in the 3rd step of Flash Tool 2014. Ive already tryed different cables and usb ports. ADB does not detect the device, neither the fastboot, but the LG Mobile Support Tool detect it.
So my question is what other options do i have in Download Mode, that is the only mode that i think i can use?
My phone is unrooted, and my laptop is windows 7 64bit.
Thanks!!

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...

So i stupidly installed chainfire 3d restarting my phone to a boot loop, i tried doing a hard reset still it restarted back to boot loop , I tried flashing a stock rom/kdz for my phone into lg support tool/r&d test tool, but every time i put it into s/w upgrade mode my pc dosent recognize it, it just says Usb device Not recognize , it also says device driver software was not successful , and i did
try installing my phone driver from here (LG P769 Support: Find Manuals & Warranty Info | LG USA) but yet it still dosent recognize it. I think this is the only problem thats blocking my way to unbrick my phone. I don't know if I'm installing the wrong driver or my phone.
If you know the right driver for my phone can you please reply with the link, I would be appreciated for your help.
my phone is also locked boot loader.
sorry for my bad english
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.

Hay guys,
I got a big problem, yesterday I tryed to downgrade my brothers LG P760 and made a big misstake.
When I tryed to go into 'recovery mode', I just used the wrong keys (VOL DOWN + HOME + POWER ON/OFF). Now my phone doesn't boot up anymore, it just hangs at the LG bootlogo. I can go into 'S/W Mode' and into 'Fastboot Mode', but if I go into 'Fastboot Mode' my decive driver is hangs in a loop. Hanging all day and night to fix this problem, but I can't do anything.... I hope anyone can help me!
Windows OS: Windows 10
Phone: LG P760
ROM: CM 12.1
Thanks a lot!

Yea, this is the last tool I used and it went fast as nothing else yet, but while flashing the stock firmware it doesn't continue at 60% and saying "Verifying phone connection...".
And does it work with Windows 10?
Thanks for your help!
Fastboot & L9 & Win10 ain't good for me, too.
But D/L mode is more basic and thus more reliable. And there are basically two ways to unbrick, online with the official LG tool, and with LG Flash Tool 2014 and a KDZ image. Only the first option works without problems for me.

Thanks for your time and answere!
Yea, I also think it's the Windows 10 which makes problems, I can't get any driver installed for this P760.
So I can just download the official lg support tool and try it this way?
EDIT: And btw... I did exactly the second step already and had also problems. I didn't did the D/L mode step yet. Can you explain how it works, I don't know how to come into D/L mode.
Thanks!
In da other Thread! In D/L mode the phone should get recognized by LG driver and a virtual com port be installed. LG software only works with LG drivers, and they sometimes don't recognize the phone, except in D/L mode.
Fir other purposes the Google SDK usb drivers are best, but then there's the Fastboot issue. But ADB should work.

The 'LG Mobile Support Tool' says that the right firmeware is already installed and then he is starting to download V20O with 599,15MByte. But the thing is, that the phone will just go out of the S/W mode while the 'LG Mobile Support Tool' is downloading the V20O. After the phone switched off, my driver is looping and always saying it can't recnogrize it. It does it like 20 times and then the phone will go on and LG logo appears. Nothing more.... :/
My P760 never quit D/L mode before or during download. Afterwards LGs recovery may appear, which calls itself something like Service Mode. This is not good, though the stock rom should initially work, but there are problems when rooting etc. In such a case leave phone connected and flash a second time. The phone should reboot to the launcher, if successful.
