Hi all,
I'll try to keep this short, I am new to this and if anyone can help/point me in the right direction to find a solution it would be greatly appreciated.
I bought an mk809iv off of geek buying (I wanted to link the page of the stick I bought, but since I'm new here I can't)
I tried rooting it but jumped in too quickly and now nothing works. It doesn't connect to the PC or television. USB debugging is not checked on the stick.
I tried rooting with an Eazyroot image from an usb stick and got stuck in boot loop, then I found a rom that was said to be working and tried flashing it with RKbatchtool 1.7 and the drivers that came with the pack. The stick connected to my PC, i tried the to flash it, but at the end of the process i got flash failed as a message.
Now the PC doesn't recognize the stick, so even if i can find a rom (stock or otherwise) I can't even try to flash it.
Is it possible that I wiped the stick clean and that's why the PC wont recognize it? I have been reading a lot on fastboot and ADB, and am wondering if I could fastboot the device so i can load a new kernel (?) onto it so it would finally communicate to the PC.
Am I wasting my time with this? Is there anyway to get the stick to work again? I'll keep reading but if anyone can help or tell me where or what to look for to learn what I need to do to get it to work, it would be really appreciated.
Thanks!
* Edit: After reading some more, I seem to have hard bricked my stick... So just in case, is there anything to do or should i just throw it out?

Hello, I recently decided to root my phone and place Cyanogenmod on it. When I did that I realized my radio was no longer working. In an attempt to just get back to a working phone for the time being I flashed a rom that I believe was just for the Nexus S and not Nexus S 4G. Due to my stupidity I am unable to communicate from the device to my computer using USB. When I attach the device to the computer nothing happens. The device does not even appear in the device manager. I have tried on multiple computers as well. On top of that the rom seems to have put me back into the stock recovery. If anyone could help me figure out just how to get USB working again I would be very appreciative.
I should note that I can still transfer files to the phone using the sd card or via ftp.
Thank you for your time and help.
Change the USB cable?
Yes, forgot to mention that. I have tried 2 cables both of which work on other devices.
What if you hold in the middle of the volume buttons (i.e. both up and down at the same time) and keep holding, then plug in to your usb port? It should come up as download mode. If it will do that you might try using Odin.
Or try a different machine perhaps?
are the drivers the same for the S as the 4g?
do you have clockwork on the phone or have you tried to run recover by holding volume up and power?
just throwing things out.
Hello, I appreciate any and all suggestions and help.
I have Odin downloaded and installed, but the computer can not find the device so Odin can not do what it needs to do. This is even the case in download mode.
In terms of recovery I am on the stock recovery. I was on clockwork but made a small mistake and now am back to stock.
I know if I can just get the computer to see the phone exists I can fix it.
If you can find the full OTA package for NS4G, you can try putting it on the SD card and flash it via stock recovery.
Also another thing worth trying is connecting the phone to an Ubuntu machine and see if it's detected or not.
I have tried looking for the original full OS. I will continue looking, but the different OS thing is a good idea I did not think of. I will attempt that now. Thank you.
I installed Ubuntu and the Android SDK and Ubuntu was unable to see the phone as well. I am going to keep searching for the original firmware to see if that will fix it. Thank you for your help so far, it is greatly appreciated.
I have found the only rom my phone will accept now is
Android 2.3.4/GRJ22/KRKC1 Radio/KA3 Bootloader
Which is for the M200 variant. This apparently the Korean version.
Hi all,
I've got a Nexus S 4G CDMA Sprint phone running Stock ICS 4.0.4 IMM76D.
My bootloader is unlocked from previous roots and whatnot.
My problem is that my phone is not being recognized by my computer at all. We're talking complete nonrecognition. No yellow triangle in device manager, no pop-ups, nothing. This phone will just not be read by my computer! I've tried different cords, different computers, re-installation of drivers after resetting my computer, installed PDA net, did a factory reset on the phone, I've literally been on Google for hours upon hours upon hours trying to figure this out and can't figure out why the computer is not recognizing the phone and why the phone is not allowing me to put it into usb mounting. It is however, charging via the computer and wall plug. I can get into stock 3e android recovery, fastboot using V-Up and Power and I can get it into download mode. It is NOT recognized in any modes by the computer nor other computers including my Linux box. The phone states that the usb control initializes but then ends a moment later. I am thinking this is a hardware issue but that leaves me with two issues:
If I was to go to Sprint to have it fixed they would realize my bootloader was unlocked thus voiding the warranty and I'd feel like quite an idiot at the store
If it is hardware related why is the charge working on the device.
I have also tried to bend up the usb plate to make it touch the pins better but that did not help at all. I am at my wits end and really need some help here, I've done everything I could find on Google and here plus more. I want to just return it but with the bootloader unlocked this is really not a possibility. I am looking for help to either become able to lock the bootloader without it having to be connected via the computer so I can then get it fixed if it is hardware related or if I can get the darn thing to be read by the computer once more. so yea, this is where I am at and I would appreciate it so much if someone could help me out, thanks guys!!!
Wireless adb in playstore should help.

That would be perfect! Only problem is that it requires root access on the phone which I am unable to obtain because I cannot access the phone. Is there a way to root the phone without having to connect it via the computer? Something like an update.zip with files able to be flashed through android recovery 3e? If I can get root access than wireless adb would be perfect.
*ultimately if I could remove signature checking in Android Recovery 3e that would work so I could in turn try to root the phone and install a different recovery to then try a different rom to see if that in turn fixes the issue.

You might be able to download your rom of choice and rename it update.zip. I'm not sure if it will flash though....someone else chime in if I'm wrong. You can use wireless file transfer if needed.

Yea I've tried that, everything gets shot down by the recovery with a E:Signature Verification Failed. Thank you for your help so far but I don't think this is something that is going to be helped. I've put in a ticket to Samsung for a repair under it's warranty. In the past I've sent in a rooted phone and they've fixed it so I think I'm going to give that a shot. Just don't want to be without a phone for 2+ weeks.
Well good luck...you are running stock unrooted so it shouldn't matter. It is a dev phone for damn sake. Sorry couldn't help.

Well if you want to download a custom rom... Since you are on this forum. Download any rom (preferably CM9 since its quite good from my experience). Flash the stable version and wait till everything is completed. Now when you flash make sure you download a recovery...eg ClockWorkMod Recovery from google market. You should now have a custom rom installed and download wireless adb as chappy said. See if that works
Hello,
I have a strange issue - one that I've had for a while now - where neither my PC or laptop will 'discover' my TF700 as a storage device and allow me to copy/paste/delete files from it. This is incredibly annoying as it means I cannot now copy on any new roms.
Strangely - I have managed to flash new recoveries onto the device, but again this hasn't change anything as far as being able to copy/paste files in Windows.. Instead I am stuck with the current (very old) custom ROM I installed a few months ago.
Could this be something to do with the USB drivers I have on my PC/Laptop? I'll be honest - I have tried several.
Could it be something to do with the cable? My official cable is a complete mess and almost in pieces, the replacement I bought (cheaply) doesn't charge properly, but again both work when flashing stuff across...
I am at a bit of a loss... Hopefully someone can guide me in the right direction.
Many thanks in advance for any help
I had the same issue, almost, when flashing TWRP.
All I did was reboot the tablet while plugged into the PC and it was recognized again.
Not sure if it will help you but it is worth a try.
Thanks for the reply.
That was not the issue, I had tried a laptop, my main PC, a couple of cables, reboots, erasing partitions etc. etc.
I finally fixed it today by flashing the latest firmware blob via fastboot, albeit after flashing a jellybean bootloader, as it would not flash properly previously.
Straight after flash of blob it rebooted, took around five minutes finalising configuration and hey presto, Windows found it and everything was well with the world again.
Cheers
Hello everyone, I bought a brand new IPPO Q78 (Android 4.0.4) via focalprice.com 2 month ago. First day of using it, and by using I mean simply installing a few apps, and after reboot, I got BOOT LOOP problem, so it wasn't able to get to tablets home screen. After lot of reading about similar problems, I was able to successfully unbrick it using (I suggest others with same cheap china tablet that are also soft bricked to use this program, it really was the only one which helped me):
http://forum.gsmhosting.com/vbb/f781/android-tablet-wifi-cpu-a10-a13-wipe-rom-easy-zakir-gsm-1656461
Here is my situation now, you can view it:
http://www.youtube.com/watch?v=cU1KYIrvZWI
Before, when it was soft bricked, at least after this android logo came the android animation that looped forever, but my computer was able to recognize and install the drivers for Android ADB device, now it can't, it won't recognize my tablet no matter what, ONLY when I press volume up and connect it to usb port, then it recognizes and installs vid_1f3a_pid_efe8 driver, which also I cannot use with LiveSuite, why? I really don't know, I've tried every possible solution found on forums (mainly here, but elsewhere also).
Whole this situation is a result of me doing the CWM upgrade/install, I'm a newbie, so I cannot tell for sure what was it, I just know it was from xda--developers forum, more accurately this thread:
http://forum.xda-developers.com/showthread.php?t=2189640
after this, poof. I think it is hard bricked, and my question is, is there a way to flash it (btw, tablet is rooted) by only having access through mentioned driver vid_1f3a_pid_efe8 and without LiveSuit, cause I would have to download and try a 100 ROM's before I pin the one that suits my tablet. It's really a tough program to deal with, but if it's the only one, I would gladly format and reinstall my Windows OS as many times I need to to get it working.
So Ive just bought a brand new U12+, and obviously the very first thing I did was attempt to root it.
Main hiccup Im running into here is that my PC wont recognize the phone while its in recovery or fastboot/download mode.
If I had to guess, I think it's a driver issue, problem is I've been searching for hours now and cannot find the proper drivers for it to be recognized. (I've also tried every USB port on my PC, both 2.0 and 3.0.)
Ive tried using HTC sync, uninstalling it and leaving that driver, Ive tried letting windows auto install the driver, and I tried a generic android USB driver, none of which have seemed to work.
PC will recognize the phone while it's fully booted to OS, and I can even command it to reboot into recovery from there, but once its in recovery I lose connection.
Not sure how much of a difference this makes, but I bought a factory unlocked phone, still sealed, with all the plastic and accessories inside the box. But when I boot into download I get the message "Security checking failed DENY", this is only supposed to show up after the bootloader has been unlocked isn't it?
Anyways, if someone could point me in the right direction for these drivers it'd be greatly appreciated.

Strange suggestion but try a different pc. My phone isnt recognised when I try to install magisk on my phone on my home pc but it works on my work pc.
I got about 9 different USB ports on my home PC and none work
Also download platform-tools_r29.0.2-windows for fastboot etc.
While you're in troubleshooting mode, try another USB cable. I had issues running fastboot commands and the like when using a generic USB cable, but it worked fine using an OEM one. Can't hurt to rule that out too.

I am using the OEM cable, straight out the box. I'm gonna try meddling with it again when I get home and see if I can get it working.

Ive done a fair bit of searching but I can't find anywhere to download older version of platform tools, I have the current build 29.0.5.
