Locked bootloader while trying to unbrick failed rom flash - OnePlus 3T Questions & Answers

Hello Guys, I have searched among the threads which have not be helpful enough to solve my solution.
Tried to use unbrick solution, flashed stock recovery, flashed twrp.. Upon completion of unbrick solution my bootloader is locked and i cannot get into recovery because md5 checksum failed on boot, system and recovery.
I've tried using the unbricking solution 3 times with no change.
right now it says modem, boot, recovery and system failed md5 checksum and just constantly reboots.
What do I do???
(bootloader locked)

And this with Qualcomm MSM download tool and the correct factory image?

i cant flash CWM on recently updated phone (LG ICS V30A)

hello,
i recently updated to the official ICS for o2x, and now i wanted to flash a custom ROM again.
so i tried with ROM manager to flash CWM, but my device is not listed above in rom manager.
i tried to install manually with nvflash, and this also didnt work, every time i try to flash cwm, it gives me this error:
downloading bootloader -- load address: 0x108000 entry point: 0x108000
sending file: fastboot.bin
/ 1024992/1024992 bytes sent
fastboot.bin sent successfully
waiting for bootloader to initialize
bootloader downloaded successfully
failed executing command 14 NvError 0x120000
command failure: partition download failed
anybody has any idea how to fix this, and flash CWM?
additional info: im on the new ics layout, my bootloader is unlocked, i have root, USB debugging was on, and i have the correct APX drivers.

Then you must be doing something wrong.... May be flashing something meant for old bootloader to the new bootloader ..... Bootloop at what point ??? Are you able to enter recovery ??? AIO Toolkit is a proven solution working for all P990's.... Also, which Custom ROM do you want to flash and for which bootloader, old or new?????

it gets me in the bootloop after changing the recovery image, and then booting in the recovery gets me in a bootloop. (bootloop only happens with toolkit) i tried the latest version available, and with nvflash, i tried it with cwm 5.0.2.0. im not flashing a rom cuz i cant flash cwm yet

Then you might be choosing the recovery for old (GB) bootloader ... Since you are on new bootloader, you will have to choose recovery for ICS bootloader... Use recoveries given within the toolkit itself....

[Q] Stuck at Service Provider Splash Screen, and CWM recovery is broken

I have the p880g model, I have rooted the phone and tried flashing CWM onto it.
Now, when I try to boot to recovery, I get "ERROR: boot image signation; Critical failure: unable to start kernel"
And when I try to boot regularly, I get stuck on the service provider splash screen (WIND Mobile).
Is there any tool I can use to get out of this? I had USB debugging enabled before this all went downhill

have you unlocked your kernel before you tried flashing cwm?

Do you mean unlocking the bootloader? No I didn't, I found out after the fact that the p880g can't.
I used this method to root it: http://forum.xda-developers.com/showthread.php?t=1886460
And then just tried using ROM Manager to flash CWM and then I tried rebooting into recovery.
Ah, didnt see that you have canadian version. You need unlocked bootloader to flash cwm trough rom manager afaik. What you can do to fix your issue, is reflash kdz file. There is a guide somewhere on the forum.

So it is fixable? I'm not exactly sure what a kdz file is, would you be able to point me to the guide? I'm also worried my phone won't be able to do it because I was on V09b development software, not whatever the release stuff was.
I had this same problem with my P880g, back before I realized CWM doesn't work with that model. I fixed it by re-flashing the V10C KDZ to my phone. However, it was already running V10C, so I don't know how yours will be affected.
The thread on how to flash a KDZ is here: http://forum.xda-developers.com/showthread.php?t=2069723
Flash the kdz file with the kdz flash tool and put mode on emergency
NOT emergency cs that wont do anything

[Q] Need help with TWRP boot loop

Boot loop
Moto x 1060 rooted on 4.2.2 with TWRP 2.7.7.1 installed. I tried to restore. TWRP says restore completed but when I try to reboot into the loop I go. I can access TWRP but nothing else. I have two TWRP recoveries but neither works. My computer doesn't see the phone when connected, so I can't flash. Any help would be greatly appreciated.

hope that helps u
When I restore with TWRP it shows successful. Then when I boot it goes into a loop. I have 2 recoveries and they both do that. MY computer does not recognize it so I cannot flash.

Your computer should recognize it in fastboot mode (NOT TWRP) - you need to be the bootloader screen (AP Fastboot Mode). Follow the guide in general "Return to 100% stock" to flash the entire SBF for your carrier. DO NOT ATTEMPT TO DOWNGRADE. Only flash the version you are currently on or higher.
Everything you need is in that thread, including the necessary drivers. If your phone isn't getting recognized it is either because you do not have the drivers installed, OR you are trying to connect when booted in to TWRP. Once again, this is wrong. You restore using your PC from the BOOTLOADER screen, NOT TWRP.
101
When I am in boot loader mode and try to connect with RSD Lite the phone is seen as "fast boot" connected but nothing I flash works. I have done this before and the phone was recognized but after installing TWRP it is not, nor can I flash anything, it says failed.
Thanks Sam. I got RED lite to work and all is well. Again, many thanks

Excellent! Glad to help. As you probably already know, you can now flash TWRP back on and re-root. Good Luck! :good:
P.S. I sent you a private message - please check your PMs.

I cannot flash or install SuperSu or TWRP. I don't really want to install TWRP because that caused the original problem. I need SuperSu but when I try to install it says "there is no SU binary installed". Phone says device is unlocked and Status code 3 and I get the bootloader unlocked warning screen. Should I reflash 4.2.2 and start over?

TWRP does not cause problems - likely your issue was un-related. You cannot install SuperSU without TWRP. You do need to flash TWRP - use the latest version from here: http://techerrata.com/browse/twrp2/ghost
After you flash it, type: fastboot reboot-bootloader and immediately boot into TWRP. Click exit and it will offer to root for you.
If you insist, you can flash stock recovery back on afterwards which will remove TWRP.

I did not face this exact error, but have faced error like image verification failed and my phone was bricked. Installing stock Lollipop didn't help. So I installed stock Kitkat via fastboot, and it worked, my phone booted successfully to Kitkat. Later I upgraded to Lollipop. Try this and let me know if it works.
Thanks for replying to my post
As it was a soft brick
I was searching so many links in xda

You have 2 choices with this.
If you can still boot into TWRP,
1. Flash the Beta Update.zip
2. Power off phone.
3. Press up button whilst powering up phone.
4. You will now be in stock recovery and you can perform a factory reset.
5. the device will now boot in to N beta but will be missing the vendor apps.
There is another way to fix if this doesn't work. Tell me if this method works first.
Edit: I just read in the op that you flashed the update and had stock recovery.
The reason it won't boot is because you need to have b322 flashed and you have to factory reset to repair the corrupt file system. To do this follow these instructions.
1. You need to flash the Boot, Recovery and System images from b322 in fastboot.
2. Then enter stock recovery (Vol + and Power)
3. Then factory reset (this is essential as it repairs the file system and enables boot)
4. The device will then boot.
5. (Optional )If you want to go back from the beta you have to flash the rollback.app to b300 through th dload method first then you can flash a Android 6.0 through the dload method.

I seen you PM. I am not sure it will wok by flashing B182. I think you have to flash B322 first.
Regards
fist you have to flash stock recovery from emui 5(android N) through fastboot.
second , download the rollback package,extract it and put it on dload folder of external storage.
third, turn off the phone , and press vol up + vol down + power button together to enter forced update mode.
if it is successful system will boot and you should flash android M firmware using dload method then u should unlock bootloader,install twrp,wipe /system /cache /data and then flash update.zip(android N) and hw_data of your firmware one after another.
i hope this help you.
still phone is not booting
I redownload b322, extracted Boot.img System.img Recovery.img Recovery2.img and Cust.img with
http://forum.xda-developers.com/showthread.php?t=2433454 Update Extractor
Flashed all .img true fastboot
But still nothing
Stuck on bootloader screen "Your device is unlocked, and can't be trusted"
Maybe i need flash some more images from b322.
Its look like phone cant pass bootloader.
Any sugestions?
P.S. Phone still have warranty, but booloader is unlocked
and fastboot oem relock ************** ends with failed.
"Failed - root cant trusted"
Sugestions how to lock it?
I had my phone bricked from testing cm, and going back to stock. My solution was to flash dload and recovery from the 182, followed by dload flash of 182.
@richish
caution : these commands will format the partition
can u use these command ?
"fastboot format /system"
"fastboot format /data"
or "fastboot erase /system"=> this will erase system partition
Phone is live now.
I downloaded DC-Phoenix and bought 15 credits
flashed stock B182 via DC-phoenix and phone booted.
I recomand this apllication for everybody who have similar problems.
THX for everybody who helpped.

How can i sign up for an account, it alway said wrong username or password !:crying:
DC-Phoenix is not cheap but it also cured my phone after bricking it with flashfire where all other methods did not work.
if you use it follow the instructions carefully and do the 2 step flashing although it will work after the first one. if you don`t do the second flash the partition sizes are wrong and a dload update will fail.

Hi everyone
I would like to share the problem that i am having with my p9 , so maybe i can get your help.
Firstly i had L19C185 version and i changed Oeminfo in order to install c636 Beta 7.0 Nougat.
I installed the nougat but then realized that i dont have stock apps in my phone, so by mistakely tried to install TWRP for 6.0 Marshmallow and my problem started here.
Now my phone can not boot. its stuck in Phone is booting now ( the screen when you unlock bootloader after huawei logo) , and its never booting. it stays like that.
I tried to flash rboot.img , recovery.img and System.Img from fast boot. but whenever im trying to flash system.img after boot and recovery.img, a get an error and never succeeded to flash system.img. Im trying to flash these .img files from L19C636b180.
Can you please help me or give me some advice because none of mobile services couldnt fix and flash new software. maybe because they dont know exactly what should they do. and in my country i couldnt find anyofficial huawei service provider.
Please help me how to fix my phone.
I also had serious problems with flashing the thing back to stock.
TWRP was broken too for me.
I've done that to fix it all
The ONLY way that worked for me was
1. Download EVA-L19C636B168 from here http://forum.xda-developers.com/p9/development/rom-stock-rom-eva-l19c636b168-t3419586
2. Download that SRK tool http://forum.xda-developers.com/p9/development/tool-srk-tool-huawei-bootloader-root-t3374068
3. Flash the recovery from the SRK tool, you can do that with the tool or directly via fastboot (i don't know other proper source for the correct recovery img)
4. Put the image EVA-L19C636B168 (UPDATE.app) in the "dload" folder of your sd card
5. Start phone in dload mode (Hold all 3 buttons at start) and let the update do it's job
What about recovery??? Does 3 button combination works? Whats heppens if u hold volup and power button when turning phone on!
Situation looks similar what i had.
Only solution for me was dc-phoenix.
U have tu buy 15 points to flash phone (15eur) But it works.
I'm 99% sure that there are bootloader comands what is same as for dc-phoenix,but i dont know them.
