Not able to boot into recovery mode

My "Coolpad Note 3" is not booting into recovery mode after Flashing Cool ui 8 V22 Rom & TWRP Recovery. However Normally its booting absolutely fine and its quite stable Rom. But I seriously need to flash TWRP in order to install SuperSU and Xposed Installer. Anyone Please suggest any solution Asap.
(Also My Titanium Backup(Apps+Data) could only be restored after granting root access).

Did you flash the correct recovery for your model number?
Have you tried flashing the recovery again?

Yes I Have flashed the correct recovery with SP FLASH TOOL (Mtk 6753 Scatter file). It shows that it will boot into recovery mode but again screen blanks and same process repeats.

Did you try booting to recovery using adb?

Do you know of your bootloader was unlocked before you flashed the recovery?
If it was locked then that is why it won't boot to recovery.

Yes, it's the same for all android.
adb reboot recovery
This still doesn't work if your bootloader was locked when you flashed your recovery.
If the bootloader was locked, you'll have to flash a copy of your stock recovery.
Then unlock the bootloader, then flash the recovery. It will probably work correctly then.

As I Know, Coolpad Note 3 comes with pre-unlocked bootloader. And Earlier I had TWRP installed in it with the same method. I dont think so The Bootloader was Locked as I Have flashed Cool Ui 8.....nd that was done quite easily.

Ok, if you had TWRP on it before then it isn't locked.
Did you at any point create a nandroid backup while that version of TWRP was installed? Have you tried flashing that same version of TWRP?

Yes, those are nandroid backups.
Can you flash the recovery that you used to create those backups? Or is that the same recovery that you're trying to flash now but can't get it to boot?

I dont remember the exact version of Twrp as its not officially available for my device. But ya..I had tried to flash 2-3 recovery.img 's (including the one which I flashed earlier). But no one worked...it just repeats the same process.

The device may have came with bootloader unlocked when you got it, but you flashed a stock update Cool UI 8, if that stock update came with a locked bootloader as part of the update package then your bootloader is locked now, and that would still explain why you can't flash or boot to TWRP.
Verify whether the Cool UI 8 v22 firmware itself came with an updated and locked bootloader. It has nothing to do with whether your device came with unlocked bootloader.

Ya I Have checked...Coolpad has locked bootloader for this firmvare version. What should I do now....Should I flash the earlier version of cool ui 8 or Is there any method to unlock ot manually?
(Ps: Not able to find Adb & Fastboot drivers for this device)

I'm not sure about the bootloader, I didn't find anything about unlocking bootloader for Cool UI 8 v22. Does it have a "OEM unlock" setting in system settings? If so, enable it and then see if you can flash/boot TWRP. Try fastboot with the following command:
fastboot oem unlock
But I did find something about how to root your device, if the information is correct. You might be able to root what you have then use FireFlash or Flashify to flash the Xposed Framework and get it working. You probably won't have unlocked bootloader or TWRP though.
But, you also might be able to downgrade to your previous firmware but I'm not sure if that will unlock your bootloader or not. The locked bootloader might not allow you to downgrade your firmware.

Honor 8 problems faced while relocking bootloader and returning to stock EMUI.

Hie Guys
Good day
I have an india version of honor 8 FRD-L02 with noghat B340 update (latest in india).
I ran into a problem when i tried to return back to full stock and locked bootloader.
Things i did which didnt helped :
1. Had unlocked Bootloader and TWRP (latest).
2. Taken full backup of my stock EMUI 5.0 rom in twrp.
3. Used custom roms for a while and now while returning back to full stock i restored the old EMUI 5 backup and i was back on EMUI 5 fully functioning.
4. Flashed Stock EMUI 5 recovery and it flashed well.
5. Now i am on stock emui rom and stock recovery now i wanted startup warnings to vanish.
6. I tried to relock bootloader via fastboot and it asked for full wipe...and fone formatted itself via factory reset and on restart no warnings of unlocked phone but the fone booted into Erecovery with a warning that data partition needs to be formatted.
tried formatting but as i reset my fone, the fone goes back to stock recovery and doest start.
but if i unlock bootloader again, the fone boots up fine after the warning message.
Can anyone help me to go back to full stock with no startup warnings.??
thanks
you can try booting into bootloader
flash twrp
format data
boot to bootloader
flash stock recovery
boot to system
(you may still have the warning message as bootlaoder will be in relocked state)
If you want your phone locked and not re-locked, provided that you are starting from nougat and your bootloader is unlocked: use rollback package and then flash an emui 4 firmware image, your bootloader will be locked not relocked
Download the latest firmware from here: http://www.hihonor.com/in/support/
Then using my guide here:
https://forum.xda-developers.com/honor-8/how-to/restoring-relocking-bricked-frd-l04-t3666360
Flash it on ur phone. After that u will be on marshmallow. Then do a full update and u will be on Nougat with a locked bootloader.

Huawei MediaPad T2 7.0 not Pro: BGO-DL09 (BG Oh, not Zero, DL Zero 9)

Hi, sorry if I posted in the wrong section. But I cant seem to find any info on TWRP or even official Update.app for this MediaPad T2 7.0 not Pro BGO-DL09. Things done:
1. Bootloader unlocked. (Huawei unlock bootloader page, fastboot oem unlock [the code] ok)
2. Update to the latest version via OTA. (Android 6.0 Emui 4.0 Build number BGO-DL09C209B008)
3. Fastboot boot twrp that i borrowed from mediapad m2 8.0 (official twrp) (not working, operation not allowed)
4. Cant seem to find this particular BGO-DL09C209B008 in official Update.app format.
5. How to actually install and patch boot.img for magisk if I dont have TWRP?
6. Every time I fully shut down the device and reboot it, that dm-verity warning showed up. How to get rid of it, without relocking the bootloader? Will flashing TWRP wipe the dm-verity screen?
7. No. I cannot just use any Update.app that I can get, just because the front is BGO-DL09. The region code is different. See the C209? Unless I can get my hands on any C209 region firmware, Im not going to cross region flash it.
Any help is very appreciated. Thank you.
Sorry to bump. Is there anyone here using this BGO-DL09 and successfully find the official recovery firmware package? need the file, just to be safe before doing anything. yep bootloader is unlocked already.
Have you found any solutions?

Off topic question: What is the latest EMUI/Android update version available for your T2 7.0 device?
Bootloader unlocked not get code

Is the bootloader unlocked? Do you know which model you had? Do you know which version of EMUI you had? Also for future reference do not make new threads without looking in guides because I think the answer is right here. https://forum.xda-developers.com/honor-8/how-to/to-emui5-custom-roms-tested-openkirin-t3638445 . Next time you post try to be more helpful because everyone here will try to help you if you help them help you. Some people may not respond if you do not leave information, or communicate that you need help to provide the information.
If you know you had EMUI 5, this should work (assuming you use the correct firmware files and have unlocked bootloader still). What did you wipe in TWRP?

yes, the bootloader is unlocked, I had the FRD-L09 model, I had the EMUI 5.0. I wiped everything accidentally with advanced wipe.

Next time be more careful. Here are some steps for you
1. Flash TWRP 3.1.1-1 (fastboot flash recovery twrp.img)
2. Download Firmware (If you are in Europe The L09 firmware up top should be what you use. If you are in Asia use the L09 firmware at the bottom.)
3. Move the firmware to your External SD if present and name the folder "Stock Firmware" using TWRP MTP
4. Factory Reset in TWRP (NOT ADVANCED WIPE)
5. Flash your region file before update.zip
6. Reboot to recovery in twrp, this will run EMUI stock recovery
7. Tap factory reset, wait.
You may need to Unlock the bootloader again, but your phone should be okay.

Please help me to unbrick my phone !!!

Hello guys,
Last week i received my Redmi Note 7 Pro with india global rom inside with bootloader unlocked.
I tried to install TWRP and root but on every reboot it disappeared... So i decided to relock my bootloader , with fastboot oem lock, in order to make a clean unlock after that ... What a bad idea, my phone is now in boot loop in recovery mode with "this miui version can't be installed on this device" in Mi recovery.
ADB is working when i select Miassistant in Mirecovery , i can launch fastboot mode but it's impossible to flash anything beaucause my bootloader is now locked.
So i tried Mi Flash Unlock Tools to unlock my bootloader but it ask to me to change some parameters in MIUI ... Too bad my phone doesn't boot to MIUI !
So i tried the hard way with MIFlash with rom stock in EDL mode ... Too bad my MIUI account is not allowed to make it on my phone !!!
So i tried the hard way n°2 with QPST/QFIL in EDL mode with elf , xml files contained in rom stock (i tried india and china rom stock) ... To bad QFIL is crashing after "Wait for 3 seconds"...
Any ideas guys on how i can do to unbrick my phone ???
Many thanks to you.
Ok so you should have never locked the bootloader again as there were far better ways to do a clean install
Now since the bootloader is locked most system level changes aren't possible and in order for you to use the EDL method you need an authorised account (which isn't easy to get), Most Authorised Mi Service centres have one, try to visit one.
Most probably the last method you suggested doesnt work cos of the locked bootloader too... :-\
If anyone on 10.3.9 & facing bugs & want to downgrade then unlock bootloader & then download minimal adb toolkit extract it & copy the extracted fastboot rom files into minimal adb folder & then put your phone into fastboot mode & then run clear all & install.bat inside the extracted folder & wait for it to finish & you will be able to downgrade because you wont be able to downgrade with mi flash, its a tested process by me as i bricked my bootloader unlocked phone which was only going to fastboot mode, i recovered by this processprocess, but i am not sure if it will work with locked bootloader or not please check & confirm
Hello guys,

It won't work with a locked bootloader and flashing an older update without clearing the current MIUI will enable anti rollback protection which will brick your device and the only way to unlock it would be to use an authorised account available at service centres.
I also have this problem. Xiaomi is making a mistake by limiting edl to some accounts.

My note7pro is also running arb1 , but I'm not managing to follow your steps, there ir no clear all bat, only flash_all.bat When I run flash_all.bat, the output is only the contents.
How exactly did you run?
Anyway, i've tried to manually run the commands, and I get the output:
