I see they are flashing custom files / ROMs on the Kindle Fire using fastboot. I believe we are limited on this due to our current bootloader state, but does anyone with experience with Fastboot know if this may be a possible working option until we can get CWM / recovery ?
I agree, can someone please try this? I've seen romified asking this question several times but no one seems to have tried it. The chances aren't great, but it's definitely worth a try.
might be as simple as "adb reboot fastboot"
and then "fastboot oem unlock" or other commands (I'm not too familiar with them myself)
This harks back to the (not so long ago) days of flashing via fastboot on my HTC Magic, which have since passed since I move onto a SGS II.
Edit: Oops it wasn't romified who asked this previously. Can't remember who it was. But either way, that's not really important.
I have not asked about fastboot yet as I just though of it and did some quick research. I am comfortable hacking roms and decompiling files and what not, but bootloaders and hacking recovery is new to me (for now anyway) As soon as I get to where I can I will dig into it further but if someone knows it isn't going to happen with this bootloader, no need in wasting time on it. It could open the door for other possibilities as well. I tried to get fastboot to recognize my NT but no luck. It was just a quick try though.
Did you manage to get the NT to get into fastboot mode though? Probably using the adb reboot fastboot or adb reboot download command (unless we find the hard button shortcut to it)?
I don't have the Nook Touch yet, but will probably be getting one to play with soon (the gf has her eyes on one). Either way, the more capability unlocked, the better.
If you can get the device into fastboot, it's a matter of looking carefully at the USB device tree and seeing that you have a fastboot device listed, then digging through the strings until you find a string you can use to communicate with the device.
If Fastboot isn't included with the NT, it is available with a number of other software packages.
I know it's part of one of the Lenovo LeTools packages, for instance, which is available for download for Windows hosts. If you get the copy from LeTools, be aware that it will install (or try to) the LeTools.apk that's bundled with it from your computer to any bloody Android device that's attached, not just to Lenovo devices. So you may want to delete LeTools.apk after installing and before connecting your NT.
Or you might want to try leaving it there as an experiment. The apk does some interesting things, one of which is make your device discoverable via wifi, at least if it's a Lenovo branded device.
The release of LeTools I just confirmed fastboot for is available at http://consumersupport.lenovo.com/us/en/DriversDownloads/drivers_show_5004.html release IN12STW151WW5.exe.
You don't need to install everything to get fastboot - you can unzip the installer a couple of times to get to the install.msi file for just the tools.

Hi guys,
Wondering if anyone here has the know how to help.
Im fiddling with some new Kobo arcs, the 7HD and the 10HD and im having some bother with installing a custom recovery img.
For simplicity sake im going to refer to them as the same device as they are both behaving the same way
The device is rooted, and I am able to flash a custom recovery made by Jenkins builder but its not functional, when you boot to the recovery OS it just goes black and the back light flashes on an off (screen remains black it just lightens up)
At this point I can reboot as normal and adb to it and flash the original recovery img and all is well.
As far as I can tell its bootloader is unlocked but there might be a second bootloader im not able to interact with yet, possible called uboot?
From adb I am able to reboot the device in to bootloader and fastboot and both function as id expect, but the problem im having is booting directly to fastboot in case I bugger something up which would allow me to fix it.
I can boot the device in to a "mode" that tries to install an APX device, ive tried using various adb, fastboot, and composite drivers and nothing seems to work, ive downloaded some old NVidia APX tegra 2 drivers ive found but these fail to work with the NVFlash utility that comes with it, it says unknown device found, which would make sense given the utility is at least 3 years old
So firstly,
Does anyone know what might course the customer recovery rom to fail and yet flash like it is doing, if so any suggestions where to start to look for a solution?
Secondly,
Does anyone know much about this APX mode and how to actually put it to good use the driver appears to work and communicate but im needing something desktop wise to talk to it...?
hope you guys can help
edit
ive answered some of question 2 myself, it appears its a pain in the arse by all accounts and not as user friendly as I was hoping, I can send commands to it but it appears that commands may need to be "signed" of sorts as I don't get any response other than acknowledgment of the command sent, ill monitor the USB traffic and see if that sheds some light, it also appears that NVflash (not to be confused with its cousin in the GPU arena) is also hopelessly out of date and once again Linux is needed to get something more updated, if there is ANY help at all id appreciate some input

I know this is old, but how did you flash the original recovery? I think I need to do this so that I can install the update ZIP for the Kobo 10. CWM is failing to install the file.
Hello,
First off, I've gone through the forums and I have looked up other posts and despite everything I cannot figure out how to get my nexus 7 tablet to be recognized by the computer (I tried and after two days of searching for answers I decided to make a post). I like to include this information so people don't assume that I post without browsing or haven't tried anything yet.
The thing that I am having troubles with is that I have a nexus 7 tablet that is softbricked, I have already gone through a lot of ways to fix that problem (I found the best solution is this:http://forum.xda-developers.com/showthread.php?t=1809195). However, the issue is is that I cannot get my computer to recognize the nexus tablet to flash it and restore it back to factory settings.
I have installed and updated the device drivers on my computer, but still I have had no such luck. I found that ADB doesn't recognize the device whilst in the Bootloader, but still will not recognize the device in recovery mode. If anyone has any tips, or suggestions that might work PLEASE let me know, at this point I'm getting desperate and any/all help would be greatly appreciated!
Thank you!

adb is not designed to be usable in bootloader mode. You need fastboot for that. If you have the fastboot.exe program in the same folder as your adb stuff, try this:
fastboot devices
If it reads, then all you need to do is fastboot flash the various .img files back to the tablet. There are tool kits that do this for you, but I prefer doing it manually as there are less chances of things messing up and if they do, you're more likely to know at what step which could be useful for further troubleshooting if need be. It is important to download the correct img files due to differences between the generations and wifi / data enabled ones. There is a flash-all script that you can find in the download of the factory images, which might make it easier, but you can just manually flash the separate files as sometimes you don't need to bother with them all (like the bootloader) though if the script works, then it'll be fine and might make it easier if you are not familiar with the commands.
If you don't have fastboot at all, just grab it from here: http://forum.xda-developers.com/showthread.php?t=2317790

You won't get adb in bootloader mode.
You have to use the fastboot command.
Please tell the OS on your computer.
Use the tool in my signature as an environment.
Download 7zip, and install that.
Then go here and download the proper image for your device.
It would either be "Factory Images "nakasi" for Nexus 7 (Wi-Fi)" or "Factory Images "nakasig" for Nexus 7 (Mobile)".
Grab the 4.4.2 version.
Extract the downloaded file with 7zip into the "Work" folder in the tool form my signature.
Then extract that "nakasig-kot49h-factory-83d93b5f.tar" file with 7zip.
Then go into the folder that came out of that, and extract the "image-nakasig-kot49h.zip" into the Work folder.
And enter the following commands while in bootloader.
Code:
fastboot oem unlock
fastboot erase userdata
fastboot erase system
fastboot erase recovery
fastboot erase cache
cd nakasig-kot49h
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot reboot
Make SURE you grab the correct image for your device. Wifi or Mobile.
I also assume that you know the .img files should be in the Work folder before you type thse commands into my tool.
Hey guys, first of all thank you for the speedy replies and steps I should follow.
Right now I'm using OSX but for the tablet I'm using a virtual Win7 machine to try and get this damn tablet to be recognized by the computer. The process is being delayed a little bit because my micro USB cords are being temperamental, meaning that the tablet has no juice, and when I mess with it (using the power + volume buttons to boot to bootloader/recover) the cord comes unplugged. I know automatically you guys are going to pinpoint this as the source of the issue (mainly because I would too), but it works fine if just laid flat and stays connected. It just has zero charge so when it disconnects/reconnects I literally have to power it back up, just need to wait for it to have some charge before I tinker with it more.
I will post updates after it charges.
Although I already thanked you guys, thanks again for speedy reply. It's much appreciated.

I suggest to STOP!!!
If you are trying to restore the device and the cable disconnects in the middle of it, it might not be recoverable. That would be one of the few ways to really damage the tablet as they are pretty difficult to hard brick. Don't half ass it with stuff like this. A good cable is not THAT much and will certainly be cheaper than a new tablet or getting it to a point where you might have to send it somewhere for service.
I'm not familiar with Macs, but if you are more so, then this might be better than using a Virtual set up:

It's actually working fine now (in the sense that the computer can now read it). The Virtual Machine also works just as good, but for some reason the toolkit I'm using won't properly return the tablet to the stock image using the SkipSoft Android ToolKit, so I'm going to have to try and find another way.
Thanks for your guys' help.
Where to begin? Logic would dictate, the beginning.
I'll do my best to be brief with the backstory.
Months ago I ordered a Jide Ultratablet to use as my portable workhorse. At first things were peachy until a rather monumental lag began to manifest every 15-45 seconds. It made the device impossible to utilize in any productive fashion, so I contacted Jide and opened up a support ticket. After months (in no way an exaggeration) of barely responsive correspondence, during which I sent them a video to demonstrate the problem, they finally came back to me with an email containing a link to a compressed folder containing the Remix 2.0 images, and also a link to a rather vague and complicated tutorial on how to flash Remix 1.5 manually to a device. (In fact, I tried to include a link to the tutorial, but I am unable to since I haven't posted to the forum enough. I am happy to PM it or email it to anyone who might like to help) I can only assume I am meant to apply the same logic to the Remix 2.0 files they sent me. Seemed a bit dicey at first glance, but while I'm by no means an expert, I'm no slouch in this arena and I'm a very quick study.
Now, on to the proverbial meat and potatoes:
If you were able to contact me for a link to the tutorial in question, you will have undoubtedly seen that they indicate one should use ADB-Fastboot as a means to flash the recovery image. No real surprises there. I have ADB and Fastboot installed on my PC (Windows 10). I also have the ADB drivers installed and have confirmed the addition to my PATH. (eg: ;C:\ADB) I can also confirm that it is working fine since I am able to pull up a terminal and issue the ADB command and it gives me the usual wall of commands. The problem is that my device (Ultratablet) is not being seen by ADB. I have checked my USB drivers and they are all up to date and installed properly. My PC sees the device no problem and there is no indication of any sort of connection error. I've also tried different cables and ports. Yet, I can't access it via ADB and thus am unable to issue commands to my device such as "adb reboot bootloader" or "fastboot reboot-bootloader".
My next logical approach was to attempt forcing the device into fastboot mode using the hardware button combination, which is not listed specifically for the Ultratablet anywhere, I might add. (Power key + Volume up) It brings me to a boot options menu with the selections "Continue/Fastboot Protocol/Recovery Kernel/Reboot/Poweroff/Forced Recovery". Ateempting to select Fastboot Protocol causes the display to shut off for a moment, the device to vibrate once, and then the display to turn back on back at the same menu full of selections.
So, in summary, I am expected to flash the device using fastboot and yet I can't even get the device into fastboot mode, let alone issue commands from my PC terminal. As I highlighted near the beginning, teh Jide support team is incredibly unresponsive and not overly helpful. I have notified them of this same set of issues, but I don't expect to hear back in any expedient fashion and I thought one of the mighty members here on XDA might be able to help me come up with a next step in the meantime. I'd cerainly love to be able to use my shiny new tablet.
In any case, thank you for your time.
Kind regards.

Bump? Anyone? Still swinging in the breeze on this one. No word back from the manufacturer, as expected. =/
I have the same problem

I know it's been 4 years but did you find any solution to this? I'm asking because I have the same problem. I decided to downgrade to Remix OS 1.5 in order to root (I have tried 5 rooting apps with no success) but my device refuses to enter fastboot protocol. The whole idea was since I can't find a way to root the damn thing in its current state maybe I can manage it with its older OS version. All this just to turn it to android root apps "testing ground" device. Oof.
Hi all,
Came by a Blackview BV6600 from someone who gave up on it - shipped saying that the device was 'corrupt and couldn't be trusted'. Went back and forth with their crappy customer service and gave up, sold it to me for cheap. It seems like a decently rugged phone but it does have a lot of bloatware and according to some threads on here about the mfgr I don't know if I trust them too much.
I'd like to wipe this phone, and I'm finding it difficult to locate a generic 'How to' for flashing a new OS to a phone. Disclosure; this is the first time I've done something like this. My experience is with computers, I know phones are a different beast and the user has much less freedom due to specifics of the hardware. If I say anything based on incorrect assumptions please correct me.
Again, what I would like to do is akin to installing Linux on what was a Windows box. I'd like to ****can as much weird chinese bloatware as possible (upto and including the entire OS) and replace it with some basic clean open source software. It seems like LineageOS does not have a version for Blackview phones, nor does it have a generic image. I notice that the Android open source project has 'Generic System Images' https://source.android.com/setup/build/gsi#flashing-gsis which sounds like what I want but references a vbmeta.img file which itself, as far as I can tell searching the forums, is likely manufacturer dependent, maybe phone dependent.
Anyway, I'm taking all the steps I see across enough sites to suggest they are platform-independent and won't brick my phone. Been following this video
since it's relatively recent and addresses my specific manufacturer.
So far I have:
Got developer permissions (go to Settings-About Phone, click build number repetitively)
in Settings-System turned on OEM unlocking and USB debugging
Figured out how to put this phone model in fastboot mode (hold volume up during restart)
Installed ADB and Fastboot (Linux), pinged the phone with "adb devices" and checked it's partitioning with " 'adb shell' <enter> 'getprop ro.build.ab_update' " no output, so that suggests 'A only'.
Next step seems to be:
oem unlock using fastboot. I seem to be having trouble here. In fastboot mode connected via USB, I can't detect the device. "Waiting for any device". 'adb devices' gives no response. No idea why. Phone screen looks exactly like in the video, hooked to USB that did return output for USB devices in normal boot mode.
Once I get over this dumb hump, I think I'll need to find a version of TWRP that will work on my device, install TWRP.
At this point I'm even more at sea: Most places suggest Magisk, but I've also seen explainers to wipe the old OS and install LineageOS.
If anyone has advice on what to do from here, specifically the near-term issue of not being able to find my phone via USB debugging while in fastboot mode, please let me know. But of course, long term I'm gonna need to know how to shovel this **** the phone came with out of storage and replace with a clean install so that is welcome as well.

This Oneplus X seems to be more difficult than my previous attempts for installing TWRP and custom ROM. I keep getting stuck and nothing returning once in fastboot and executing command "fastboot devices". I just keep getting "< waiting for device >" .
I think I have ADB installed right because while the Oneplus X is on and in normal mode (developer settings enabled with OEM unlocking and USB debugging enabled also) ADB connects. The USB drivers look to work fine because I can see the device (including SD card storage) and transfer files. in ADB and typing in ADB devices, I see the device.
When I run adb reboot bootloader and execute fastboot devices using command.com with administrator privilege, it just returns another prompt. It doens't show any device. I get the same results with Powershell with administrator privelge.
I'm already on my 2nd machine trying to do this although it's a windows 10 also just w/o updates for six months (was off and on the side of office). I had the same issues on my newer machine and thought it's the windows 10 machine I'm using. Researching the internet and here, I see others mention it though I didn't see any solution. I don't have a Linux machine (never really used it though had redhat installed eons ago somewhere). I guess I can do a refresh of my 2nd/older machine and not do any updates to see if that may help with any driver conflict though I don't see any indicators since adb can see the device. I thought trying to install TWRP via sideloader may work but I don't see tutorials and commands via that way.
Also I'm using ADB 1.4.3 in the 2nd windows machine. I had the Minimal ADB and Fastboot version on the other machine.
Anything else I can try?
P.S. The Onyx seems to be harder than putting android on my old HP touchpad! Putting a Tmobile rom on a AT&T Galaxy S4 and custom rom on a Oneplus 2 seemed much easier than the Onyx though unsure why. Onyx and the Oneplus 2 were comparable manufacturing years iirc.
On the 2nd machine, i did a windows 10 reset to basically refresh it (like a fresh install). I started over again and managed to get past the fastboot device problem and it's showing it now. I think the prior problem was the device and driver and even with a re-install, can't seem to get past it. The only difference I did with ADB install was not opting to install google drivers.
I got the bootloader unlocked and the recovery.img file done. Basically I'm following the direction from this page - https://www.technobuzz.net/root-oneplus-x-install-twrp-recovery/ - which seems to be aligned with most youtube and I think same as old pages here.
Now where I'm stuck is when executing "fastboot boot recovery.img" I get the failed (remote : dtb not found) and can't seem to find a solution to this one. Some sites say something about the partition?
Thoughts? hopefully this machine is not too old/dead for some comments/guidance unless I'm posting on the wrong section.
well to share back here and for closure.. looks like the recovery image i used on the site above must be for a different OOS. doing some further searches here and different terms and jumping to another thread from a search result thread (lol), i read that i needed a specific twrp for oos 3.1.4. (odd since recovery is supposed to be independent of ROM version, but that seemed to have work). guess persistence pays after all.
it really did heavily matter having the device recognized properly by windows 10. once i got past the blank fastboot device command execution, i got the another issue due to the phone not knowing how to boot into the recovery version i was trying to install, at least that's how another poster in another thread explained it. hence the right twrp had to be used for oos 3.1.4
