Please Help - My phone stucked on bootloader warning (Urgent)

I was following guide from this thread.
"http://forum.xda-developers.com/moto-x-play/general/untested-how-to-root-moto-x-play-t3211941"
I did everything step by step, bootloader unlocked and once phone get started too then after flashing twrp i was not getting anything when i tried to reboot twrp asked to install supersu and i installed it.
THen i read somewhere don't install supersu when twrp asked ?
then i did process all again, but can't go through warning message of bootloader.
Please help i just want to root, don't want custom rom or anything.

did you take a backup ??? if you did restore it. otherwise do a factory wipe from twrp if it does not help Then download twrp flashable marshmallow stock firmware and flash it.

I can get into recovery twrp, but i can't get into phone.
I flashed twrp-lux-2.8.7-r6 & then flashed super su 2.46 ?
is there any solution without flashing stock firmware ? i can get root and override this problem.

Can anyone give me link to stock firmware ? Indian version i was on Marshmallow. & how to flash stock firmware

download from here forum.xda-developers.com/moto-x-play/general/rom-xt1563-brasil-stock-6-0-twrp-t3272979
if twrp doesn't detect the backup then connect the device to a PC in fast boot mode and type command "adb devices" it will show you your device id . now take out your external sdcard go to twrp backup folder and make another folder inside backup of the name of your device id and keep the backup there and then restore from twrp.

It takes good 15-20 Mins at Moto Logo; Wait patiently and if it refuses to boot after that then do this :
Download latest TWRP and flash it. DONT FLASH SUPERSU from TWRP when prompted at boot.
If this does not solve either, download Android 6.0 + TWRP from this Link
Save it to TWRP \ Backup and then boot to TWRP, Restore and Boot as per instructions in that forum.
If this also fails, then simply flash FULL STOCK FIRMWARE from here and follow instructions given at here.

[Guide] Safely unlock bootloader on official MM

UPDATE: This is now unneeded because threr is a faster way ro unlock bootloader on official MM here, he updated for official MM
Hi, I discovered an unlock method for official MM!! This maybe long but's it totally safe
You need:
Adb and fastboot environment ready PC
LP RAW File
Android 6.0 Beta Unlock tool
Android 5.0 One-Click Unlock tool
First version of beta MM (Z00A) (Z008)
Official MM zip (find it on Asus site)
Thanks to all people upload these links
Just do the following:
Flash the lastest LP via AFT (using raw file given above), wipe all data. If you already on MM, you have to downgrade
Unlock your bootloader using 1 click tool given above
Boot to stock recovery and sideload the first version of beta MM
Unlock the bootloader using MM beta unlock tool above
Boot to stock recovery
Two case here:
Case 1: You can't boot stock recovery
Normally boot your phone (to Android)
Setup it as a new phone
If it shows there is a new firmware, don't update!!!
Enable Developer options, then enable usb debugging
Copy the official MM zip to external sd card
Open command prompt, run adb reboot recovery, accept the adb permission if prompted
After it boots to recovery, select Apply update from SD, then choose the zip file you've copied before
Wait for it to update, it may stuck at flashing splashcreen, don't worry, it's trolling you, may be Asus forgot to update the script
Goto step 7
Case 2: You can boot stock recovery
Sideload the official MM zip (adb sideload <filename>.zip)
Goto step 7
7. Flash this TWRP (fastboot flash recovery <twrp>.img)
8. Root your phone using this method
9. Reboot, if it shows "Your phone has failed verification bla bla..", then you've success. It may reset loop like note 7 in the first time start, don't worry.
9. Enjoy :highfive:
Note: If you're facing with battery problems on MM, factory reset it in Settings > Backup and Reset > Factory Reset > Erase everything
Successfully on my ZE550ML
The warning screen is normal so don't worry and there is no way to fix it for now

Yes, BL will be relocked once you upgrade to MM.
If you want to unlock MM BL(6.0), refer to this thread.
Or you can downgrade to Lollipop referring to this thread. Then your BL(5.0) is unlocked.

Upgrade to MM
Hello folks!
2 week before MM was released i'ved opted to unlock my ZE551ML BL and therefore install twrp and a MM custom ROM..
so here´s the thing i stayed with the ROM for about 3 weeks and honestly..it works very well..but when i knew that 6.0 official was coming out i decided to go back to stock..i did it following manny tuturials avaliable for me to get my BL Re-Locked..but unsuccessfully..so i followed mr_gourav2000 tuturial (http://forum.xda-developers.com/zenfone2/development/stock-rom-ul-z00a-ww-2-20-40-168-t3354526) and reverted to the WW_Z00A-2.20.40.183-to-2.20.40.184 (hopefully i can get the sshot in this post) version...since my BL is unlocked i can´t get no updates..my question is:
Is there anyway to go to MM 6.0 by ASUS with the current status of my phone?
is there anything i can do to revert this??
Cheers to everyone

Just download the update package and rename it to mofd_sdupdate.zip, copy it to internal storage. Then reboot to stock recovery, the update will automatically start. This should work if you have lastest stock recovery

Have you downloaded the correct build? There are build for MM bootloader, if you flash the normal builds, it will fail and reboot to recovery again. Gapps is the same for all builds
After you install that special build, do not update to newer nightlies, it will fail. For updates, check the link i give you and see if there is a new MMBL build.
About that, here is the post: http://forum.xda-developers.com/showpost.php?p=68542370&postcount=8551

hello friend, I tried to install the CM13 ROM that indicated me and I get Error 7 in TWRP 3.0.2.0, I have Android 6.0 (.134) official and if I can change kernel and flash rom SuperSU but change with a new MM Blows I can not (CM13, AICP, beanstalk ....) thanks for your help!

Run the script again (i gave you in above post). Download the CM13 in that link, not in the OP of CM13 thread. Flash that CM13 and Gapps (Gapps is universal for MMBL and LPBL).
May be you have corrupt download, I'm currently running CM13 on MMBL

Hello, I have finally found the solution, the problem is the recovery, the TWRP 3.0.0.2 da failure with new builds, I Flashed next on the link you put me through adb and now it works, thank you very much for everything .

[Guide][How to]Update Bootloader/Firmware to OOS3/H2OS2 w/o installing OOS/H2OS

Okay guys first let me tell you why I have created a new thread just for updating the BL and Firmware ,
I know we already have methods of updating like:
1. flashing the full OOS3 zip through stock recovery ,this method is quite simple for the ones who are on stock recovery and just want to update their OOS version.If you fall in this category then you have no purpose here,you may leave.
2. Is method provided by our fav helping hand @Joshwin Aranha ,that method is sure for the rest of us who dont fall in the above category,but is way too long,although simple and effective still "long".
I created this thread to help the CM13(Official or Sultan's)//any custom rom using new BL,users who want to update their BL without flashing the OOS through the tedious way just to update BL and users who are stuck on bootlogo due to old BL with roms using new BL.
Here I will guide you through the required steps to update our bootloader "In easiest and fastest way without wiping and restoring anything".
So what are we waiting for ,lets start .
Prerequisites
you will need two files for this process,nothing else.
1 . First one is BLUpdater zip --->Here.
2. Second is TWRP compiled from latest sources use either This or the one from Here<--use v41 or use Sultan's from Here OR if you are Martin's fan like me and want to use his MutiRom TWRP goHere.
PS:I am assuming you have Unlocked Bootloader and have either
official/blu_spark/sultan's/ Multirom TWRP installed,in a working condition on OOS2.x BL(if not what are you doing here).
Note: make sure oem unlocking is checked in developer options in your current rom,else updating the BL may cause it to get locked ,and you will have to unlock it again and flash the recovery manually through fastboot itself.
Now the steps
1.First copy both of the above files in your sdcard or otg or ext-sdcard,any place accessible in recovery.
2. Now boot into recovery Choose Install and choose the "OPXBLUpdateOOS3.1" zip and flash it.
3. Don't reboot now ,go to Install again ,this time use "Install Image" button in lower right corner,navigate to folder where you copied the new TWRP,you should be able to see the file,select it ,choose recovery in the next menu and flash.
NOTE:If you chose to use Sultan's recovery.zip then just flash it normally.
4. Don't reboot come back to TWRP home ,goto reboot and recovery ,if TWRP says no OS installed ignore it.
Now voila you should have updated your firmware/BL.Congrats.
You can now install any rom that supports the new BL.Older roms won't boot on the new MM BL.So check the rom thread before installing the rom and later on quacking here about your device being stuck at bootlogo.
Notes
i)Neither I nor XDA will be responsible if your OPX bricks or explodes or ditches you and flies to space.
ii)We are not touching system partition so last installed ROM will be intact.
iii)This guide will leave you into bootable rom only if you have a rom installed that works on latest firmware.
iv)This can also be used to restore all your OPX partitions back to OOS3.x partition state,if you messed any.
v)In case you are using latest nightly (cm13) and face bootloop - go Here
psst:If you are not diggin the new BL,and wanna downgrade again ,back to old BL,check this post.
PS: (second one,I know) This guide was made by taking inspiration from Joshwin's post and devtry method.

No it wont,right now almost all the custom roms need to update to support new firmware.Only latest cm13 nightlies are booting now,also aosp compiled by olddroid for new BL(shh its only for testers right now)
also maybe the MIUI8 port ,just posted in the forums.

I'm a litte bit confused.
Currently I'm on nighty October 1st. (cm-13.0-20161001-NIGHTLY-onyx.zip)
Can i update the Bootloader with your method and after that booting up my current nightly version?
Or do I have to update after the bootloader update to nightly version 12 (the currently latest)?

no update the BL using the steps above ,then flash the latest nightly.That way it would be good.
Or you can flash nightly first then update BL.Choice is yours.I recommend updating the BL first.

I followed your guide with a locked bootloader, and now I'm in bootloops . Just suggest you put a big red "make sure your bootloader is unlocked" in the steps, not in the footnote.

Thanks! I actually relocked my bootloader not long after installed cm13, and disabled "unlock oem" in "developer settings"(I don't know why I did this). So both system and rec is inaccessible, and fastboot is useless in this case. Fortunately I followed the unbrick guide: http://forum.xda-developers.com/oneplus-x/general/guide-mega-unbrick-guide-hard-bricked-t3272108 and get the old bootloader back. Now I could enter CM13-09-28 with all my data intact.
Just hope to let people know the hard lesson I learned, and how to deal the bootloops.
And guys, NEVER RELOCK BOOTLOADER AGAIN!

taking you wanna flash ashwins cm14 right. You just wanna follow the instructions in first post and then flash the cm14.No need to install the whole Oos zip.
This way you should have updated BL and working cm14.
Just flash the cm14 after booting into new TWRP

I've just followed the procedure from OP and all went smooth as butter. Thanks
Directly after that (without reboot) I've installed the latest CM13 (with GApps) and Arsenic R24. Working as a charm

How to unbrick my ZTE Axon 7 mini b2017g

Dear Seniors.
I am facing great hardship because my phone is stuck at boot logo.
No booting in recovery mode to flash another rom.
I did unlock bootloader of it by using tuliptool with success. After that i flashed custom rom in it. after reboot it is happening that.
Please suggest to recover it.

Did you flash twrp after unlocking? Did you make backup of stock ROM? Perhaps find a version of the factory firmware and flash that.

Dear I have no backup and i flashed TWRP recovery.......
It is to aware you that i did relock bootloader now my phone is working properly. but i am unable to enter recovery mode. !!!
Now my phone is running android 6.0.1 B02
But i am failed to root this rom uptill now due above mentioned problem.

In easy words......... my recovery.img has been corrupted. I have no idea to get rid of this situation.

I planned to unlock my Mini's bootloader this weekend. After reading this post, I decided to act later until the root cause has been figured out.

Several people myself included have been able to use tuliptool to successfully unlock and root the device.

mine is hard bricked too. but I think it is worse than the case listed on the op.
if you want to hard bricked these are the steps:
follow the procedure to install the Spanish ROM 6.1, than another android m b12, than finally the android seven......use tulip tool and install twpr fine, root ect. amazing ROM.......buuuuut......I lost my IMEI somewhere in this process, and the original FTM which had a small menu changes to another static one, without the menu.
I needed this menu to open the com port to fix the IMEI. than I had the brilliant idea to re-flash android M via twrp (without modifying the zip file to remove the recovery, something I knew so well from the older axon mini).
results:
-lost twpr because the stock ROM wrote over it,
-cannot boot the OS because I flashed android m but the phone had the aboot 7.
-i now have a brick
I need a genious to sujest something to bring it back to life........sh....t...sh...t.....sh...t
any chances I could inject aboot7 via ADB through my dead recovery which somehow the phone recognises? ADB shell still seems to be working
thanks

Need backup img for tb-x304f

They don't have images like Google devices, but flashable firmwares.
http://lenovo-forums.ru/files/category/287-lenovo-tab4-a10-tb4-x304l/ has it, second from the bottom, underneath all the OTAs. Double check that you got the 4F and not the 4L one.
I don't have this device so I cannot help you with it if you have issues, nor can I say this will work for you. I also really don't profess to be any kind of an expert so do ask in one of the other Tab 4 threads if needed... but I do have the TB-8704F & have restored it to stock several times and I would assume the devices to be identical in process so I can give you a guide if needed! The general path is:
Download the zip and extract it
Download and install Xiaomi Mi Flash (some say to use QFIL but it often throws up errors and sometimes requires flashing in multiple passes, when Mi Flash doesn't)
Plug your device into your PC
Put your device into Emergency Download Mode, easiest way for you is probably to first reboot to TWRP which you luckily already have installed
In TWRP go to Advanced>Terminal>type Reboot EDL
Open Mi Flash and it should see your device. Click Select, open the images directory in your extracted firmware and it should detect the flashing process XML
Click Flash, then leave everything to complete
I will warn you that you will lose everything on your device. There's no way around this that I know of, nor would I suggest it anyway. Just back up everything before doing the restore.
+ Good luck! But honestly I'd first weigh up whether you really want to update to 8.1 since you're already on a perfectly-working device. They already pushed the OTA once and had to retract it because of the amount of serious errors it had - but that's your call entirely.
