[Q] Bootloop, Cant seem to fix it.

I'm new to rooting and all of this type of thing, i figured I would first start with my HTC Flyer. I successfully unlocked the bootloader, and installed SuperUser, upon installing greenify and i tried to install the Xposed Framework, and my device now is stuck in a boot loop.
When enter the bootloader and do a factory reset or try to enter factory it completely freezes, and when i try to connect it to my PC via fastboot the PC says that the USB device that is connected cannot be recognized and fastboot will not work. Did i completely fry this device? Also if you have time I couldnt figure out a proper way to flash a custom rom so if anyone has a guide for that I would appreciate a link to that as well.
Thank you so much!!

Huawei Y6, how to remove FRP?

Hi guys, i got the Huawei Y6 SCL-L01 phone and i wanted to install a custom rom, so i tried to install TWRP first, but since there wasn't a Y6 version (there isn't a Y6 version for anything pf ) i used the P8 version and it installed but when it rebooted the phone was stuck at a screen that say FASTBOOT & RESCUE MODE. The phone seems to be unlocked according to that screen but the FRP is loocked.
Things i've tried so far
Installed ADB latest version, extracted Recovery Cust System and Boot images from an official stock ROM.
Tried all available drivers from Google TP_Link and Intel for my phone.
The screen i am stuck does not work with ADB commands, the device is not recognized.
Fastboot commands work and it sees the device correctly, the problem is every time i try to flash the images from the stock rom i get FAILED message due to FRP Lock.
Format userdata and cache doesn't work either.
Vol + / - and Power button combinations also have no effect, it only shows that screen regardless of what i press.
I've searched the web and the XDA forums extensively since this happened and tried every possible solution i could find even if it was meant for another device.. no luck.
And here's my question, how can i possibly remove the FRP lock by only using fastboot?
Please somebody help, i am like half a day away from decorating the wall with this piece of ****
PS: I am not able to upload screenshots, sorry about that.

I'm stuck with this problem too. The exact problem. Have you found a way to fix it?
I have exactly the same problem with my Huawei Tablet.
If I boot with the original ROM and look in the "/log" - directory with adb shell, there is a cust.log. The contents say, that the specific ROM is not original or factory.
I think even the bootloader is unlocked, there is a kind of signature checking.
EDIT: @Asdforcer: Have you tried to boot the original boot.rom with "fastboot boot" - command?

vodafone tab speed 6 vf-1397 vf1397 stuck checking connection request firmware/help

could anyone help with a seemingly bricked tab speed 6, attempted to root using kingoroot and it failed causing connection issues to google so i was unable to add a account, after hard reset and booting in to recovery i have wiped the cache and reset to factory, however now the tablet is stuck on checking connection and doesn't go any further with or without sim card.
after searching and searching i have come up with nothing apart from this threadhttp://forum.xda-developers.com/general/xda-assist/stock-rom-vodafone-speed-tab-6-vf-1397-t3329343
it looks as though he is having the same problem.
assuming kingoroot has corrupted the rom and i need to reflash to repair it,
i don't know if it is a generic tablet it appears to be made by alcatel but im unsure.
i also do not know if i could use a firmware from another device or even custom rom, anything will do as long as it doesn't end up in the bin
i also have another which hasnt been messed with and was wondering if it would be possible to back up the rom from it and reflash it to the bricked one, if so could anyone steer me in the right direction
could anyone help me locate as rom and flashing tool that will help
thanks in advance, apologies if this is posted in the wrong place.
You said you had a second one, you don't have to root it, just follow this tutorial and hopefully you should be good to go.
no bootloader
hi thanks for your reply however upon backing up the other tablet, it had still not solved the problem does that tutorial back up the Rom or just system files I created the backup.ab and used adb recovery to no avail...., however, I gave up on this method and was going to use a custom recovery on the the working tablet to back up the rom, however when I tell adb to reboot to the downloader it just reboots the tablet there seams to be no downloader on either tablet, so even if I had the rom it appears I could not flash it via the downloader as I can't get to it, nor sd card as there is no option to flash it, it's really bugging me now as it's obviously only soft bricked, any more help would be greatly appreciated thanks in advance also to add fastboot lists the device but when I tell it write the recovery it says waiting for device
inexperience
thanks for the help I am quiet inexperienced but determined so any help pointing me in the right direction would help thanks

What command do you do to tell adb to reboot to download? What command to you give fastboot to flash the recovery?
hi thanks for the quick reply im ujsing adb reboot-bootloader , it reboots the tablet and then greats me with the vodafone start up logo then asks me which country im in, as for attempting to flash with fastboot ive tried fastboot oem unlock to unlock the bootloader ( says waiting for device) ive also tried adb push c:\adb\backup.ab ( doesnt seam to recognise the psush command as it cycles through all available commands , and attempted to flash recovery with fastboot flash recvovery cwm.zip ( says waiting for device) adb reboot sideload just reboots the tablet same as adb reboot bootloader, thanks for all your help.., ikt is really bugging me i appreciate your time.
I don't know if download mode is accessed differently I've found this post that seems to Suggest hold volume up and down then connect until battery charging appears http://forum.gsmhosting.com/vbb/f272/vf-1397-a-2047715/ this is for unlocking it seems, but don't seam to be able to get it to work, earlier I removed root with kingoroot from kingoroot app, also to no avail and rooted again both root removal and rooting were successful but still tablet stays on the checking connection screen when rebooted, I was hoping the removal may of fixed the issue but no...., I was thinking if I could get back custom recovery on it I could do the same to the working one I have begrudgingly so I could back up the working ones rom and use it to flash the bricked one, but I don't really want to risk bricking that one either, but was considering finding another rom from another model the same chipset and flash it with that but obviously no download mode means I can't do it..
if it's any help The recovery mode states android system recovery <3e>
LMY47V release keys
reboot system now
wipe data/factory reset
wipe cache partition
power down
enable adb
they are the only options,
again thanks for all your time and effort

You can't always unlock the bootloader via that command and you'll need to have the bootloader unlocked to flash a custom recovery, if you can find stock images on the web you can flash them via fastboot.

Also to restore an adb backup you do "adb restore filename".
unfortunately there is no stock image anywhere on the Web, is there a good app I could use to save the rom from the working tablet without rooting, really don't want to risk rooting the working tablet

Did it work? I see you left a "thanks" so I assume something happened.
hi, I give up on the tablet, I've been asked to see if I can give it another go, but don't know where to start, I still have a working one but no idea how to get the rom from the working one to the bricked one. thanks for the help you gave me to begin with.

I have a couple tricks up my sleeve and that is, you know how you said when you ran adb reboot bootloader? Run adb shell instead and it should give you a command explorer, from there, type "su" and report results, you should see either a root request on the device or a hash sign in the coommand shell.
Just a quick question
Did you ever manage to get it working if so how did you go about doing it as i attempted to install a custom boot animation and it appears to be stuck in a constant boot loop as such i'm not really sure what to do with it or if it is savable. Any response would be helpful. Thanks.

So I have Doogee X6 phone it's mt6580 android 5.1 , few days ago I decided to root it and I done it with Kingoroot app and it succeed. Today, I tried to install custon recovery so I head to Needrom and download twrp img from there and tried to install it with ADB FASTBOOT FILES WINDOWS like in this XDA tutorial
https://www.xda-developers.com/how-to-install-twrp/
I followed the steps then I ran to the problem where I had to unlock boatloader with "fastboot oem unlock" next I install the recovery img using "fastboot flash recovery twrp-2.8.x.x-xxx.img", after that the phone started to reboot and try to enter twrp with some failure lines like:

How to unbrick a rooted smartphone with USB debugging off and blocked bootloader?

My smarthphone is a Doogee F7. I bought it two weeks ago, just to root and to study. In the last week I rooted it with Magisk, no problems. However in this morning I received a notification I had a Magisk Manager update available, so I updated it. I opened up the manager, and saw there was a newer version of Magisk available also, so I installed that (directly, recommended) after reboot came a softbrick:
"Orange State. Your devices has been unlocked and can't be trusted. Your devices will boot in 5 seconds" occurs infinitively.
So, the USB debugging in my phone was off (yeah, now I know that it must be on ) and the bootloader was blocked also.
I can access the "Android Recovery" screen. Therefore, I tried to "Wipe data/factory reset" and after reboot the system, but it didn't resolve. I tried also "Wipe cache partition" but it did nothing as well.
So on, at fastboot screen I tried to unlock with the command "fastboot oem unlock" but it was not possible:
"(bootloader) Start unlock flow
FAILED (remote: '
Unlock operation is not allowed
')
fastboot: error: Command failed"
I read about test point but my phone doesn't have screw, the cover is glued.
I tried to use ADB sideload as youtube video whose title is "How to Unbrick device using TWRP/CWM ADB sideload [HD]" , but my computer recognize my device as "MTB USB Device", and when I am updating the ADB interface is not recognize even I searching for.
My phone doesn't have TRWP installed, when I rooted I just run TRWP for install Magisk.
I tried to upload images here but I am a new member and I can not until I reach 10 posts.
So, I am wondering about my phone can be recovered. Please, if anyone can help me, I will be very grateful .
Edited: The rom is the original, the stock rom.
maybe this helps...
