Touchscreen unresponsive after "fastboot oem unlock" (Lenovo Tab3 10 Business) - Android Q&A, Help & Troubleshooting

Touchscreen unresponsive after "fastboot oem unlock" (Lenovo Tab3 10 Business)
Hi there,
I just got a TAB3 10 Business - Type ZA0X - Model ZA0X0125SE, 32 GB.
I thought it would be nice to root it and be able to boot TWRP, so I first tried to unlock the bootloader.
I booted into fastboot and from the ADB and Fastboot SDK Platform-Tools I ran this command:
- "fastboot oem unlock" : that appeared to be succesfull and ended in "OK"
- then with "fastboot boot twrp.img" (the img file I found here: https://www.androidfilehost.com/?fid=457095661767138880 I booted into TWRP but found out the touch screen did not work
- then I booted into normal mode, the tablet was reset to factory settings and I ended in the setup screen of Android: "Choose language".
But I can not choose a language as the touchscreen is not working.
Can anybody understand how the oem unlock command has resulted in an unresponsive touch screen?
And any idea how I can solve this?
Thanks!

Actually it was not the "fastboot oem unlock" command that caused the issue, but the "fastboot boot twrp.img" after that.
Although my firmware had a different type of version number (TB3-X70F_S000004_161208_ROW_P), I decided to flash the device with the SP Flash Tool and the "TB3-X70F_S000025_160527_ROW" firmware that I found here: https://www.androidfilehost.com/?fid=673368273298936487. Thanks Tzul !!
After flashing this firmware, unlocking the bootloader, flashing TWRP and installing SU (to get root access) went smoothly.
After an OTA update to S000026 (TB3-X70F_S000026_170208_ROW, I had to install TWRP and SU again, but everything seems to work fine now
Apparently my original firmware version did not work well in combination with the TWRP version from Tzul.

Do you have firmware file left? I can't download it, stuck on "Searching for mirrors..."

Honor 4x che2-l11 no boot.img or recovery

I installed an incorrect custom recovery after rooting with King root. After thinking I did the wrong thing I flashed the bad recovery as my boot.img. So now my boot.img and recovery don't work and I'm on a boot loop. Please help

Is your bootloader unlocked!? If yes, then fastboot flash the boot.img and the recovery.img of your stock ROM.

No it isn't I just used king root! I can't do it from here either can I ?!
Then you have to unlock it first by getting the unlock code from Huawei. Here are the steps...
1. Go to https://hwid5.vmall.com/oauth2/port...huawei.com/en/source/plugin/hwlogin/login.php and login with you Huawei ID CONTINUOUSLY FOR 14 DAYS. Don't have a Huawei ID? Then click on "register".
2. After that, you'll be redirected to the unlocking website. Make sure to check the box below.
3. Next, you'll be seeing 5 boxes. Then...
• Enter your model number in the first box
• Enter you serial number in the second box (Can be found in settings or at the back of your battery)
• Enter your IMEI in the third box (Can be found in settings or at the back of your phone)
• Enter you Product ID in the fourth box (Dial *#*#1357946#*#* in the dialer app to get it)
• And lastly, enter the verification code in the fifth box provided beside it (The verificarion code should be a 4-digit code)
4. After entering all of the required information, click the blue box below of all boxes then you'll end up seeing your unlock code (It should be a 16-digit code)
5. Download and install Huawei Update Extractor, Minimal ADB and Fastboot and the drivers. Make sure that USB debugging is enabled in settings -> developer options.
6. Download also the stock ROM and don't install of course, you don't have a recovery.
7. Open Huawei Update Extractor and extract the update. Make sure to only extract recovery.img, boot.img, and system.img.
8. Move the 3 extracted files to the directory folder of ADB. While in the ADB folder, after moving the 3 files, hold Shift and Right click and select "Open command window here".
9. Get a good working USB cable and plug in your device (make sure the device is powered on and the screen is on as well) and type in and enter " adb devices". A pop-up will appear on your phone asking to authorize. Press okay or whatever positive it says. After authorizing, it'll be displaying a code. Maybe like ••••••••••••• devices. If not, then try adb devices again.
10. Once finished with that, type in and enter "adb reboot bootloader" which will reboot your phone to bootloader.
11. Once in bootloader mode, you'll be seeing a text below saying "PHONE Unlocked" or "PHONE Locked" in red. If it says "PHONE Unlocked", it means the bootloader is unlocked, if it says " PHONE Locked", then your bootloader is still unlocked which means you still have to unlock it. To unlock it, type in and enter "fastboot devices" first and you'll be seeing a code again just like from adb devices. If that code shows up then you're good to go.
12. Next type in and enter "fastboot oem unlock ••••••••••••••••". You'll replace those circles with your unlocking code of course. Your phone will now perform a factory reset and will say " PHONE Unlocked" now. Congratulations!!! You've unlocked your bootloader!!!
13. Now we have to flash the files. If you want to flash the recovery only, then type in and enter "fastboot flash recovery recovery.img" and will say OKAY at the end. If you want to flash the whole system, type in and enter these:
• fastboot flash recovery recovery.img
• fastboot flash boot boot.img
• fastboot flash system system.img
• fastboot reboot
Your phone will now reboot into the system. If it's successful, then congratulations!!!!!

OMG
My phone isn't che2-l11 it's che2-l12.
Then why did your post says Che2-L11? Anyways, the method is just the same as Che2-L11, only select the UPDATE.APP for Che2-L12 not for Che2-L11. Good luck!

Ok so I was on the zzkey a website trying to get my unlock code! Then I found out that's a $130 sub key . The reason I was on there was because I can't get my product I'd due to the fact that I'm in a boot loop

Bro, you can get the unlock code from emui.com no need to use your phone because yes you are in a boot loop but instead, use another device or a computer.

Hey guys i have ended up with a huge problem here.
I am having the bootloop even with a flashed CWM recovery flashed it reboots.
I am allowed about a minute inside the recovery before it reboots.
I also suspect my unlock is not properly done.
If i use getvar command it fails.
However it does say my phone is unlocked at the bottom of the screen.
I should probably flash boot to make it stable so how do i do that and does anyone have any suggestion for what i can do now?
The original Emui recovery doesnt recognize the dl folder with update inside for the original rom.
I would love to get help making this stable again.
Thanks.
I believe i had as old as firmware version B086
it was stuck there which is the reason i tried to root and unlock because it was getting very old and unstable.

Stuck in bootloop after flashing custom recovery. Please help.

I ported TWRP using Android kitchen to flash to my device (Coolpad 801es) since there isn't an official version. For some reason, I can't seem to get fastboot to play nice with my phone (see my earlier post) so I used flashify. On reboot i'm stuck in a bootloop. I did have the foresight to back up my stock recovery with flashify and transfer it to my PC first, in case something went wrong. Now, I can't boot into recovery at all and ADB isn't working since the phone isn't being recognized by my PC when I plug it in. I just want to flash the stock recovery back and fix this. I can get into fastboot, and the PC does recognize the phone in fastboot, but when I try any commands it just hangs at waiting for device. I've googled but every solution i've seen for fixing a bootloop tells you to boot into recovery to do so.
Can someone please help me out?
UPDATE:
Upon further research, I discovered the reason fastboot commands weren't working is because my phone apparently isn't whitelisted in the fastboot exe. However, if I type Fastboot followed by -i 0x1ebf the commands seem to work. Using this method, fastboot devices lists my phone and fastboot reboot reboots the phone.
I think i'm on the right track, but when I try "Fastboot -i 0x1ebf flash recovery (path to recovery.img)" the terminal shows "sending 'recovery' (10240kb)..." and nothing else. No progress indicator, and i've waited 10 minutes for it to complete which should be more than enough time to flash a 10 meg file, but there's no change it just sits there. Like I said, I think i'm on the right track but I could REALLY use some help. I can't be the first person on here with this problem. Can someone, anyone, PLEASE help me.
So, more Googling would indicate that either i'm not using the correct USB port, or that my bootloader is locked. I have tried all the USB ports on my PC (front and back) as well as two different cables, no joy. As far as the bootloader being locked, the phone is rooted which I thought meant that the bootloader is unlocked as that is part of the rooting process. I try "Fastboot oem unlock" to check but I just get "failed remote no such command unlock" and there is no OEM option under developer options on this phone. I'm trying to piece this together but I could really use some help.

Oneplus X brick

Hello guys,
i have a bricked rooted oneplus x
I had issues with the rooted rom so i flashed the newest stock rom via twrp
The phone boots up and showed the usual otimizing apps message. After the proccess is done it just the usual "let me helpt set up your phone page" and then restarts
I cant acces twrp anymore and when i try to acces the stock recovery it just shows a oneplus logo
I do have access to fastboot though (i hope that leaves some hope)
I have tried the MegaUnbrickGuide here in the forum but i wasn't able to install the drivers i need for that method
One more thing whenever i try
Code:
fastboot boot recovery.img
i get the "remote dtb not found" message
Does that have to do with developer options not being unlocked?
Any ideas on how to just get some form of working os installed on the device
(i dont care wheter rooted or not at this point have been trying stuff for hours now)
regards
Jan
First download Minimal ADB and Fastboot and install it.
Go into fastboot mode.
1. Re-unlock your bootloader using the command - fastboot oem unlock
2. After doing that, download the latest version of TWRP(which at the time of writing this is 3.1.0) and rename it to 'recovery.img'
3. Open a command window in the place you have downloaded the recovery by pressing the shift key and right clicking and then choosing the option Open Command WIndow Here... Flash the recovery using the command fastboot flash recovery recovery.img
4. Boot into it using the command fastboot boot recovery.img
5. If it still gives 'remote dtb not found' then follow this guide: https://forum.xda-developers.com/oneplus-x/help/opx-remote-dtb-solution-t3480274
6. If it boots into recovery, your phone is now fine and go ahead and flash whatever ROM you want.
Cheers!

[Doopro P2 Pro] Need help with booting TWRP

Hi, I want to install a stock official google release of android 7.0 onto the Doopro P2 Pro. If I cant do that I want to at least root the phone, the reason being that this phone is pretty well built, but the software is just bloatware, it barely qualifies as android, it also has ads. I successfully got into bootloader/fastboot, and I checked that it is unlocked via windows cmd "fastboot oem device-info". I also successfully flashed some kind of twrp into it with "fastboot flash recovery "C:\Users\...\twrp.img"".
The only problem is that this phone only has options if I boot it into recovery mode, but only a logo if I am in fastboot mode. I tried using "fastboot boot "C:\Users...\twrp.img"", which returns a remote: dtb not found error.
Now when I try to boot into recovery mode (adb reboot recovery), it just loads the bootloader which only has a logo as I mentioned earlier. The OS still boots up fine. The only problem I can think of is that I am trying to boot a TWRP that is not compatible with the device / android (6.0.1). Please somebody help me!
