Hi,
Im hoping someone can help me, I have been given a OEM tablet from where I work. I think its an unbranded Coby Kryos 7022, this the closest resembulance.
I installed clockworkmod from the android store to backup the rom, but when I rebooted, the clockmod loaded (IMG 1) and doesnt allow me to do anything, if i select reboot the device reboots back the clockworkmod. So Im stuck in this loop. Clockwork also wont mount the sdcard.
I have the Android SDK installed and followed a guide to replace the recovery.img but when it comes to replacing it i get error -1, im also unable to su in adb shell....
I did manage to get the device in to fastboot i think. As the screen was black and windows tried to load drivers but was unable to find them.
I have tried adb devices but get waiting for devices and fastboot devices and get nothing. I'm guessing i haven't got the right drivers for this device in whatever state its currently in. I have tried googles android composite adb driver with no success.
any help is appreciated

Hi everyone I first want to sincerely thank everyone that will answer to try to help me solve these problems with my nexus.
So the other day my nexus suddenly decided to stop being awesome and it started to be a pain in the ass instead.
When I turn it on it just keeps loading the booting animation of android 6 marshmallowand it never turn on. I identified this problem as a "bootloop" and i tried solving it anyway but it's being really hard and i'm almost getting no results.
I first tried with going into recovery mode. from the fastboot the recovery mode won't start, pops out a died android with a red triangle on it. Pressing volume up and power from that screen got me to another menu. I tried wiping the cache and wipe all the datas/ factory resets but no results. the crappy marshmallow animation goes on till forever.
On the screen that follow the dead android appears the error: E: failed to mount /cache (Invalid argument).
After that i tried with the famous sdk tools.
I am able to unlock the bootloader with the command [fastboot oem unlock]. however after unlocking it, if I turn the phone off and on again it auto lock itself.
i tried to flash a recovery image with the command [fastboot flash recovery recovery.img] but it won't flash. I unlock the device first, and then i try to flash the images. it says ok after the sending but on the writing says FAILED <remote: flash write failure>
same things happen flashing anything else (android factory images etc.)
I can't use adb, i d need to put the usb debugging mode from the developer options but since I coulnd't turn it on I don't know how to turn this option on.
So i discovered existed a "download mode"
Apparently for the nexus5 you have to push volume up and then connect it to the usb to enter in it. I tried many times and it just don't go to download mode (is this the correct procedure??)
I installed the last google divers, no results.
I really don't know what to do, do you guys have any ideas about how to save it?
phone details:
hammerhead d821(E) 32GB
hw version- rev 11
bootloader version: hhz12k
Cheers

I think your emmc chip has gone bad and that is why you are getting locked bootloader everytime you reboot the phone as it is not able to hold any memory.
I suggest RMA if its in warranty

OK so ur ennc chip is NOT dead, that little Android with the triangle is stock recovery, which u can do nothing with, ur going to need a PC, preferably running ubuntu or some other form of Linux with adb and fastboot installed, i cam help with that too if u need it, once u get that settled what u need to do is this, download TWRP for ur hammerhead and rename it recovery.img, place it in a folder u have access to. Open a terminal and connect ur nexus to the pc with USB cable, and boot into bootloader. Then type this into the terminal:
cd (folder with recovery.img in it)
fastboot reboot bootloader (this should boot u back into bootloader if ur device is connected right)
fastboot flash recovery recovery.img
fastboot reboot recovery
This will boot u to TWRP in which u can perform a factory reset, if this doesn't work and ur still in a bootloop, download ur fav rom and gaps and flash it, this will take care of everything
And there is no download mode on the nexus that would be bootloader mode, so let me get this right, what system are u on, and did u try manually formatting with ADB? What happens when u do, I would force format cache, system, boot, and userdata and then flash recovery, that might work

I'm in way over my head guys, so here's my situation:
I have no OS installed, for some reason I can't get into TWRP anymore (it goes to eRecovery instead).
I CAN get to bootloader screen (bootloader is unlocked).
adb does not recognize my device on device list command (it worked before, but now I can't get into the OS to turn on USB debugging and such...).
please help! I don't know what else to do!

I think the first step to fixing my phone is to get it recognized in the list of devices attached in adb.
how do I go about doing that?
In device manager I got it to recognize my phone as Android Phone > Android ADB Interface.
so I believe the drivers are updated, what else can I do to get my phone recognized in cmd adb?
If I need to provide any more details then please say, I am getting hopeless
Edit: I managed to get into TWRP. still no clue how to continue from here as I can't transfer any files from PC
I found a update.zip file on my phone's SD card, I can't remember which ROM version it holds, but when I try to flash it I get a few errors:
check_write_data_to_partition,write data error
E:unknown command [errno]
Update_huawei_pkg_from_ota_zip: update package from zip failed
Updater process ended with ERROR: 7
Error installing zip files '/external_sd/update.zip'
I think I managed to screw my phone up even more, I can no longer get into TWRP...
:crying:
Hi everyone!
I kinda screwed up here, phone was already rooted, went into twrp to flash twrp zip but forgot to use the .img
Now the phone is refusing to boot normal/recovery with the "ERROR: LoadImageAndAuth Failed: Load Error" and I think I solved it once before flashing to two partitions.... the thing is, I was messing around and disabled usb debugging a while ago and forgot to enable it.
Am I screwed now?
USB debugging won't affect you using fastboot. As long as the bootloader is unlocked or able to be unlocked you can just flash the factory images and be fine. I just had to do it.
Yeah, after messing around I found that, used Deuce's tool but didn't work, now fastboot doesn't detect the phone for some reason and I can't even get into download mode.... I'm beginning to panic haha I hope I can get the phone to be detected
EDIT: For some reason it was only on my main PC, used another PC and fastboot was able to detect my phone. After multiple flash-all and deuce's script, I'm in now again
Hey guys, in a little bit of a dilemma.
My s6, for some reason, cannot pass the flashing "Samsung" logo when booting it up. I have not rooted this phone, nor have I installed a custom recovery or rom. This phone is stock as it gets.
And I need to recover the photos off the phone. Issue is, I thought it would be simple as going into recovery mode and doing adb pull/sdcard/DCIM/Camera or something like that.
BUT I do not have USB debugging enabled!!! Never even turned on developer settings.
I tried to get into bootloader and use fastboot, but fastboot devices shows up with nothing. adb commands do not work, except when I press "install update from ADB", then only the very basic ADB commands work such as adb reboot, adb sideload etc.
So I am not sure what to do from here. Fastboot is not working (I have installed the Samsung drivers from the official webpage, but I haven't restarted my computer so i will try that).
Please help me to recover these photos :crying::crying::crying:
Hi,
If Download mode is working, flash TWRP recovery with Odin.
Go to Mount, select Data partition > Enable MTP and access files from PC.
Recover your data, then flash fresh new ROM https://forum.xda-developers.com/galaxy-s6/general/guide-tutorial-howto-samsung-galaxy-s6-t4108425
