Need help with softbrick! - Android Q&A, Help & Troubleshooting

Hello, guys.
Recently, I've tried to root a Cubot Power 4G following a guide I found online. I probably should have been more catious about it, cause now the phone is stuck on a bootloop. I tried to install a custom recovery to try and fix this, but as there was no official twrp for Cubot, I once again downloaded something that was probably shady. Thus, now the phone is stuck on bootloop, won't access recovery mode, is now turned off because battery gave out, but if I try to connect it to the pc, it will start to bootloop again. I cannot access adb, or at the least I don't know a way to, since it keeps bootlooping and I have no way to access a recovery mode(since there's no one, or at the least, if there is, it's faulty). What can I do here?

Re-flash phone's Stock ROM by means od MTK Flash Tool. You have to install the Mediatek VCOM drivers before on your Windows computer, if not done yet.

I did! Or so I think... The moment I connect it to the pc, it starts bootlooping and so the pc cannot actually connect there

Bootloop is a situation where you cannot get into the "normal" Android system. Take note that as soon Android logo is shown on phone's display Android kernel got successfully initialized, ADB & Fastboot are ready.

Lenovo P70A problems with flashing TWRP

Hey, I am new here so sorry if I'm posting in wrong board.
I rooted my P70 a while ago and everything was fine. Now I decided that I want to flash 5.1.1 on it. I proceeded to flash TWRP.
I tried it with SP flash on pc, I checked that my scatter file and recovery.img was correct. I opened the scatter file in SP, connected my phone and clicked download, but nothing happened. Only the phone started charging, I have enabled USB Debugging and developer mode. The bootloader was still the stock one. Why?
Next thing I tried is to put the recovery.img on SD card and downloading Uncletools, I flashed it and it asked me if I want to reboot in bootloader, so I did, but it was still the stock bootloader.
What am I doing wrong? Thanks a lot for any response.
Anyone got any idea?
Click download and conecting usb cable to hh
Hey,
I have the same issue. The phone is rooted but the SP flash tool will not do anything. I've read that it's because the USB drivers are incorrect. However I am unable to install the drivers as the phone does not show up under other devices but rather under portable devices. I tried to install the android sdk and use those drivers or ones I found on the web but none of them will take. I found the ADB device signed driver under USB devices in the device manager.
I am honestly at a loss here. Would be grateful if anyone has ideas I could try!
Thanks

Rooting or flashing recovery without fastboot?

I have flashed my device probably 50 times at this point trying different ROMS. Yesterday I decided to give stock another shot, but now I'm stuck. I had to flash the stock recovery to update to Marshmallow after restoring my Lollipop backup. I'm not happy with it, but I cannot reflash TWRP. When I boot to bootloader the fastboot drivers no longer work. Windows device manager says it's an unknown device and the device descriptor failed. I can't even manually force it to install the driver for the device by picking it, because it says that the driver isn't for that device. I even tried resetting my crappy Windows tablet so that it would have nothing previously installed and then installed HiSuite, but the same problem there as on my desktop. I have also tried generic "universal" android drivers and sketchy Huawei drivers from a "how to unlock your bootloader" tutorial. I have unplugged it and replugged it several times, using various different USB ports (I have 10 of them, so no shortage there).
I can't flash recovery through fastboot because that isn't an option. When in normal mode the computer sees the device just fine as a MTP device and an ADB device, but when I try to run ADB commands they don't see the device either. At this point I am really trying to find any way I can root the phone, regardless of how sketchy, so I can use Flashify to restore TWRP and go back to CM13 or an AOSP. Does anybody know a working method to root besides flashing through fastboot? Thanks.

There is none. The only safe way to root is to flash TWRP in fastboot. Right now, you can try to force update through update.app
Thanks for the reply, but:
1. I'm not looking for a safe method, just any method. I've tried the obvious suspects already (towelroot, kingroot, kingoroot)
2. I don't need to force an update, I am on the latest firmware now. If anything I may have to attempt to force a downgrade to open up vulnerabilities, but if I go back to lollipop then I will likely have issues flashing cm13.

Oh. But like I said, there is none.
I have come to the same conclusion, but I'm still hoping if somebody has rooted it in another way that they will see this thread and share their method. Otherwise I may end up stuck on unrooted stock, which will kinda suck.

Have you tried changing the drivers.?
Yes
So, I did not figure out how to root it without fastboot, but I did solve my problem. I dug out the cable that came with the phone, and using that cable my computer finally recognized it as an Android device when in fastboot mode. I don't know why it only works with that cable, but there it is, so I will have to make sure that cable never gets broken or lost.

10.1 inch tablet soft bricked

hi everyone i have a 10.1 " chinese tablet on an mtk6592 cpu with 3gb ram running marshmallow . i left it plugged into my windows 10 pc that was having issues with its modified xeon cpu . basically my daughter unplugged it from the pc used it then switched t off overnight next day it hangs on android screen and doesnt boot . adb doesnt see it so im assuming usb debugging is switched off . fastboot sees it but wont flash it.
when i boot it into recovery mode nd run a test it states it has a missing xbin file and 3 modified files but my daughter swerars she didnt root it or touch anything. now when i try to apply update from sd card it goes into the os on the tablet but doesnt list any files on the sd card . i have since swapped out the xeon for an old quadcore chip and reinstalled an os but went with linux mint . now i can only see the device in fastboot but not in adb and i get a mount error when i try to connect to pc in anything but fastboot mode . im no pro but im pretty competent on pcs but ive literally zero experience on android flashing etc all ive tried so far is from 3 weeks of reading forums online but im no closer to solving my problem does anyone have any ideas what i can do on a linux os . ps flashtool doesnt recognise it as connected either.
thanks for any help in advnce

Did you install mtk usb drivers? If not, try to install it for SP Flash Tool to recognize your device. I also got the same problem before but installing mtk usb drivers solved it. It's worth a try. Hit thanks if it helped you.

Install SP flash tool, install mtk usb drivers, download the correct rom for your device. The zipped rom should come with a 'scatter file' when unzipped. Run sp flash tool as administrator load scatter file then when sp flash tool reads your device (you can see it at the boottom of sp flash tool window), click download and wait for it to finish. That should solve to bootloop. Hit thanks button if it helped you.

I ****ed up a recovery flash... now I regret my life choices!

I have a thl knight 2, I tried to flash twrp and it's stuck in a bootloop. I can't connect trough adb, fastboot but I saw some ports in device manager. I downloaded mediatek drivers. As far as I know when I connect the phone it should be detected by the droid tools or sp flash tool but it isn't. All the drivers pop up, I tried setting them to mediatek DA USB VCOM (Android), Mediatek USB VCOM (android) and Mediatek PreLoader USB VCOM (Android) but still it doesn't find the phone. I can't use recovery and can't enter fastboot. My volume up key used to lower the volume instead so maybe they are both mapped to volume down? I have a orange state message on the android logo about not trusting my phone. It would have been better to just let the chinese government get my personal information than trying to mess with forces I don't comprehend! If anyone reads this and is willing to help me I will be forever in your debt.
Maybe if I brick it altogether I will have more chance than it just getting to the android logo.
