Soft Bricked Help!

Trying to fix a friends Vibrant...
He was running jk6 software when the phone bricked itself in his pocket (?).
Now, the only thing we can do is access download mode by holding down the power button.
If I run Odin, and try to start up the phone into download mode, none of the COM Ports detect the phone, even though he is in download mode. Conventional methods don't work (Starting up ODIN, Plug in USB, hold down volume buttons). Only way I access download mode is by holding the power button down.
Any Help?

Try switching to a different USB port.

You need to make sure the computer has the usb drivers installed. Simple plug and play won't work. Its good you can get into download mode. Look in the bible sticky and download and install the usb drivers. Also if its windows vista or 7, when you open odin don't double click it. Right click and run as administrator. Also, make sure you open odin first before you connect the phone to the computer. Good luck.

Drivers have already been installed.
I can access download mode perfectly using my Vibrant and ODIN recognizes it, but when i plug my friends Vibrant in, thats when the problems happen.

For the record, when I plug my friends Vibrant into the USB port..a message pops up saying that one of the usb devices attached has malfunctioned (Code 43). I'm thinking this is directly related to ODIN not recognizing it (although it recognizes mine)

If you can reach download mode fear not its not an issue with the phone its definitely a problem with the drivers or maybe even try a different usb cable.

Yea, but I can only reach download mode. Phone will not boot into recovery, or even start up, just download mode lol. And i dont think its the USB, seeing as how i can plug in my other Vibrant and odin detects it immediately (on the same computer).

Well if the very same usb cable and port recognizes your phone (I'm assuming you both have the same exact phones) and odin recognizes your phone and not his, then his usb port on his phone must be where the problem lies... Try looking it, or even opening your phone and cleaning his usb port or something. Or try a different computer. if you can get into download mode don't worry, you'll find a way to fix your phone.

Still having the same problems. Tried a different USB cable, different computer running Odin...no luck. Only my computer detects that the phone even exists by shooting me an error saying that the device has malfunctioned. Phone just stays in download mode...Odin doesnt detect it. I've tried different methods to have ODIN detect it and still nothing.

Had to go through this too, but didn't have another phone in download mode to test against.
Win7 x64, tried a bunch of different drivers, but in the end was running the ones that come with Samsung Kies. In my case it ended up working without the original samsung cable (just a generic one), and with a USB port hanging right off my motherboard at the back of my tower. I have two USB ports on the front of my tower and they always errored, no matter what combinations I tried (including the same cable and driver). But when I switched to a port at the back, I got past the malfunctioning USB device error. Also, it seemed like Odin likes to be running when the phone boots into download mode. This took hours but phone runs perfectly now.

N7 lost abilty to use ADB

I've had it working for a long time, then my PC quit recognizing my N7 2012 intermittently. I thought it was a buggy ROM so I tried another. Same problem, so I wiped it and flashed stock 5.0. Same problem
It doesn't recognize it at all anymore, but I can plug in my N5 and N9 and they work great. Has this happened to anyone?

Did you try reinstalling the drivers? Download official Google ADB/USB drivers and install them through Device Manager.

Yep, did all that. The same driver runs my other nexus devices fine. I wish I could remember what the Windows error message says...something like 'unplug and plug it in again, if that doesn't work then replace the device'.

Make sure you enable USB debugging on your tablet. And first time you do that and connect it to PC, it should ask you for sth like RSA fingerprint. Accept that and it should work.

I see where on a lot of replies that the tablet needs to be in USB debugging. If it's in boot loop, how can you do that? My Vista won't even recognize the tablet any more!

Ok it started working again, so I quickly downloaded the 5.1 image to flash. I got through it but now it just shows the google logo forever. I can get into the bootloader via the hardware keys, but the n7 isn't recognized as a fastboot device, so I can do nothing else with it....
What Windows tells me when I plug it in is this: "The last USB device you plugged in to this computer malfunctioned, and Windows does not recognize it"
In device manager it says this: "Unknown USB Device (Device Descriptor Request Failed)"
I can get it into recovery, but it just shows our little android friend laying on his back with a red triangle.

Try getting into Fastboot. Hold Power button to turn it off. Hold Power + Volume Down button to get to bootloader. Try using Nexus Root Toolkit when you get there or try getting into recovery and flashing something.

Why can't you get into the bootloader with the hardware keys? To get into recovery in your situation, Hold Power Button + Volume Up(for one second only) and the recovery should pop up.

I can get into the bootloader. Just can't get the device to be recognized bu the pc, so O never succeed at flashing anything.

Try using a different USB cable or port, or even try doing all this on an alternative PC.

Its the same on my laptop and desktop, all usb ports, 3 different cables...
I'm starting to think the n7's usb port is going bad perhaps.

Yesterday i flashed my Jiayu S3 to lolipop (i tought) and i just bricked my phone!
After reboot it was just dead.. when i plug into pc with USB i hear the connect sound and after 2 seconds the disconnect sound. This keeps on going until i pull the USB plug. When i look in DeviceManager i see it refresh after every sound, but nothing pops up (unknown device or whatever). I deletet all usb drivers with usbdeview, restart pc but still no changes.
I tried with or without battery, but without it does nothing at all.. i tried holding Vol+ or - or both or with power button, but nothing.
Read some threads about unbrick and install correct usb driver for jiayu s3, but all the options they came with does not work on my device!
I'm a little despered now and don't know what to do.. i get the feeling that my 2 weeks old phone is dead? :'(
My pc has windows 7
Did the flash with SP Flashtool 5.1516

Just flash it again, but this time with "Firmware upgrade " in SP Flashtool instead of "Download". Change from KK to LL needs reepartitioning, so firmware upgrade.
The reason why you don´t "see" the S3 any longer on the pc is, that the USB storage mode from KK, which is driverless for windows, don´t work right now on LL.
Once flashed to LL you will need to install a driver, for windows to connect to the S3.

@ Dior DNA:
No i can't. Phone does nothing with the buttons. Only diference if i hold Vol - then time from connect sound and disconnect sound is a little longer.. about 10 seconds. But still nothing happens.
@1testi:
Flashtools can't see my phone. I tried it a hundred times. With battery, without battery, with Vol - and with Vol +.
When i connect the USB cable i hear the connect sound and after 2 a 3 seconds i hear disconnect sound. This goes on and on until i pull the USB cable out. In devicemanager i see a refresh going on, but nothing pops up.
I'm realy despered on what to do now?

Why the SP Flashtool isn´t working any longer? You didn´t deinstalled the driver, did you? Just try to flash again with "Firmware Upgrade".
I don´t know a way to reinstall the driver in windows without the preloader. The only thing you can do, as far as i know, is to use a linux
pc to flash again. Linux don´t need a driver for SPF, only some rules.

Booting into recovery or flashtool I meant regardless of pc and/or spflashtool.
If I recall correctly:
hold volup and power boots recovery
hold voldn and power boots flashtool
If you can boot recovery then which one is it? Maybe you can restore something or manually flash preloader bin from there.

After the flash i reboot and then the connect and disconnect sound appears. So i tried differend things, but could not connect. I wanted to flash again, but flashtool did not reconice the phone and nothing in DeviceManager. That's why i thought to remove the driver and try to re-install it. But that did not help..
Holding Vol - or + button with power button or both Vol buttons with power button does nothing.. i tried to hold all combinations at least 30 seconds, but nothing at all.
I have no Linux pc or any knowhow to make a Linux pc.. or a pc to install Linux on..

One last thing you can try: remove the battery, wait a little, insert the battery again. Hold vol+ key, keep holding it and press power
button, while still holding the vol+. If you don´t see anything happening then you bricked the phone.
You will need help from a professional or at least from someone with a linux machine, sorry.

I'll try that.
You have any idea what could have caused the brick?

As i wrote above, moving from KK to LL with wrong parameter "Download" in SPF.
....and a not working recovery.

You should try this method :
darmowyinternet.net/forum/temat-poradnik-jak-uruchomic-uceglony-telefon-po-wgraniu-zlego-romu-test-point_383
unfortunately you have to translate before

Ok i tried that site with google translate and i could a little make up what they are saying.
But that is a very drastically operation, and i would like to give it some other tries before dismantling my phone.
So i googled and googled.. came here: http://forum.xda-developers.com/showthread.php?t=889128
Had enough electronics lying around from my former 27mc hobby, so searched for the right resistors,
cut up a micro usb cable and give it a try... well.. nothing! Tried for about an hour and gave up.
Then i googled on Unbrick Jigs, but for what i read they are only for Samsung phones, so i gues the trick
with the resistors were also?
So googling again... came here: http://forum.xda-developers.com/showthread.php?t=2454004
Reading the tread and the comments, someone mentioned a download for "Mediatek Driver Auto Installer".
Downloaded that and installed the drivers. Plugged in my phone and... whoohoo!! Something is happening! :silly:
My devicemanager saw an "Alcatel single RNDIS interface". I unplugged and plugged my phone a few times to
be sure it was my phone. Sooo... one step further! :good:
Then i googled on this device.. came up with all sorts of network devices, not helpfull. Then googled on Jiayu with
this device. Came up with this tread: https://www.china-devices.com/topic...vcomm-drivers-onto-your-pc-win-7vistaxp-only/
It's a tread about bricked Jiayu G3 devices, but i thought, 'What the heck, lets give it a try!'.
I downloaded the "MTK Megapack - All Tools Here!" and unpacked. Wend back to device manager and manually updated the driver
of the Alcatel device. Show all devices - browse - wend to Megapack map and there were MTK drivers for the 65xx device.
And yess.. when i plug in my phone there's the device: " MTK USB Port (COM7) "
SP Flashtools sees my phone again! :good:
Tried to flash a stock preloader, but got an error: "BROM ERROR : S_FT_ENABLE_DRAM_FAIL (4032) – [EMI] Enable DRAM failed!"
But for now that's a problem for tomorrow.. it's almost 2:30 and i have to got some sleep!
(sorry for the misspellings or telling things not clear, i'm tired and english is not my main language)

Grats!
You can google the error. This leds you in the right direction.

It's alive!!!!!! :laugh::silly::victory:
Because the kitkat stockrom i downloaded gave me the same error over and over i searched for something else.
So i downloaded TF Extreme lolipop 5.1 this morning and give it a try. And all went well. I pulled the usb plug and
pushed power button.. only vibration but nothing. Then pulled the battery and after few seconds put it back in
and try power again. Only 1 vibration.. then tried Vol + and - combinations but nothing. (dammn!)
Then plug the usb in and i saw the battery icon.. it was total empty! (because of a week trying).
So now it's charging and i hope it starts, can't wait!!
Thanx all for the effort in helping me out! :good:
Edit: Ok, so i could not wait and hit power! It shows green screen with Jiayu S3 logo and text "New Load". So i guess it's prepairing for first startup!

my s3 basic is not charging when on.. also when connected to pc thru usb, ipc shows device malfunctioning ,and there is no indication on phone..I try to connect to sp flash tool also no success..same error"usb device not recognized pops up every 2s.everything else is fine..Any method to upgrade to 5.1 now on official kk

Kinda need help, happened something similar
It happened something similar to me.
I flashed the whole ROM, bootloader included, I was very sure that my model, Jiayu S3 3GB ROM + 32GB RAM, was the correct, but still bricked my phone.
There's no problem at all when I plug it into my PC, I installed the lastest MTK drivers on windows 10, having to disable the signature enforcement.
The problem comes when I start flashing. I only mark the bootloader, then I press "Download" (on the lastest version of SP Flash Tools), and plug the phone, with the battery in it (I've tried without battery, pressing all possible combinations and does nothing), when I plug it in with the battery and pressing no buttons, the driver is detected as MTK USB Port. That's a good thing I guess. But It does not pass from the red bar, and gives me the known error "Enable DRAM Failed".
I've tried to google any possible solutions, reinstalling other version of the MTK drivers, on different versions of Windows, with other versions of official ROMs, and the result is always the same.
The only thing that's left to try is flashing it with an Ubuntu machine, which is something I do not expertise to be honest, but I'm gonna gather some info and try to do it.
However, if someone has any idea of what I might be doing wrong (excluding the part when I flashed the bootloader, I'll never do it again), I would be really grateful for any kind of help.
Thank you!

Problem with LG Spirit: Secure booting error

Hi,
A friend of mine gave me his LG Spirit H440 with the boot error: Secure booting error
In his words he tried to update the software, the phone started to lag and after a reboot the error occurred.
The guy is simple user so installing custom recovery or rooting are out of the question.
Here is a video I made of the problem:
https://www.youtube.com/watch?v=fONioh6uNms
After removing the battery the phone starts for 2-3 seconds with Secure booting error and then powers off. After that it cannot start again until the battery is removed and then everything repeats.
I tried to connect it to the PC with Windows 8.1 and installed LG drivers, but nothing happens. It's not recognized.
Also tried to enter download mode with Vol Up and connecting the USB cable, but again it just displays the error and shuts down.
Is this soft or hard brick? I'll be grateful for any help and guidance.

Try to set it in "upload mode" and flash stock rom kdz

im sorry for ignorance but FastBoot=Upload mode?

Same problem, is there a BOARD DIAG option for this phone?

Phone not recognized in Fastboot / Download

Three days ago, my phone went off by itself and I had a hard time starting again, it was just loading the bootanimation, I tried to reinstall the ROM, but it did not go into TWRP, although the message Recovery appears on the screen, I insisted and after several attempts, I got into the recovery, formatted everything and I installed the AICP ROM again, and I had to restart,my phone freezes in the LeEco bootloader, then again I insisted until the ROM finally started, but soon realized that it was taking too long to start (30 minutes waiting and nothing).
So I rebooted again, and from then on, I can not go into any mode anymore, trying to access the TWRP, the phone only stays on the Recovery screen until reboot after 2 minutes, when letting the phone try to start the ROM, it only stays on the LeEco screen and restart after 2 minutes, when entering Fastboot, it enters the screen in Fastboot mode, but is not recognized by the computer, not even as unknown device, the same for Download mode.
Is there anything I can try?

Doesn't seem like a a fried motherboard. In my experience, If you fried the CPU, you would still be able to access Fastboot, if you fried the GPU part of the chip, or if the LCD has failed you would feel vibrations..
Do you thin it is possible that you accidentally put the phone into EDL mode? It can sometimes be hard to get out of, and it will give you similar issues.
To leave EDL press and hold volume down and power for 1 minute or longer.
Try this
Install the All in One tool and use it to update your android and fastboot drivers. Afterwards see if the computer recognises the phone port connection by going to Control Panel>System> Device Manager* ( Even though, you may not see the drive, you will maybe still see unknown device or te port)
Maybe a Brick?
If it does not see the phone or show a unknown USB device with port 9008
Try placing the phone into EDL mode by pressing and holding the Vol Up (+) and Vol Down (-) together while simultaneously connecting the phone by USB cable to the computer. Do you see the port or phone now? If you see port 9008 you possibly are bricked, follow the steps on my unbricking thread., if you can not get back to TWRP, or fastboot,and the phone keeps a charge. Then I would think that you are definitely bricked.
Other possible issues
The issue could be the battery. Have you tried using other USB C Cables? If you can use a different usb cable let it charge for a couple of hours then see if you can get into TWRP again . If you can enter fastboot mode try reflashing TWRP, you can use the All in One tool for this.

Thanks for answering. I've tried everything.
But I can not see the smartphone when connected. USB drivers are properly installed (I used to recover other LeEco x651, x526 and x520 devices)
I left it restarting for more than hours holding the power button and volume down, no results.
The device does not appear in the Windows device manager in any way, not even as Unknown or 9008 port.
I tried several usb cables.
There is no communication with TWRP or ROM installed and neither with the computer, even though I enter into fastboot / 9008 mode. Only LeEco / recovery logo and Fastboot screen.
I think my main memory is damaged or something.

Well that sucks, if you feel like sending to the phone to China for repair, you can find several shops that are offering to repair any damaged Leeco for $10 and an average cost of $30 for resoldering. On the TaoBao website, use Chrome for translation. Some of their ads mention overseas repair
If it's memory it would be an easy fix for them.
If you don't want to fix it, I highly recommend the Mi8 if it's within your budget, its a perfect phone and you can find them for close to $300. My brother has a Redmi note 6 Pro which is also really nice. He paid $190.
Good Luck.

Thanks for answering. I've tried everything.
But I can not see the smartphone when connected. USB drivers are properly installed (I used to recover other LeEco x651, x526 and x520 devices)
I left it restarting for more than hours holding the power button and volume down, no results.
The device does not appear in the Windows device manager in any way, not even as Unknown or 9008 port.
I tried several usb cables.
There is no communication with TWRP or ROM installed and neither with the computer, even though I enter into fastboot / 9008 mode. Only LeEco / recovery logo and Fastboot screen.
I think my main memory is damaged or something.
