How to flash the Kernel correctly?

Im having a lot of troubles flashing a new Kernel to my Play. So i wanted to ask if I do something wrong.
Heres what i do to flash a new kernel
1. Unlock bootloader
2. flash new System.img and/or flash new boot.img via fastboot (fastboot flash system system.img / fastboot flash boot boot.img)
For now i succeed in flashing a new system.img which gives me root access, but everytime flash a boot.img (no matter what kind of kernel, even stock) I end up in.. hm not really a bootloop - nothing happens at all, screen doesnt even turn on.
Heres what i do to make my phone work again.
1. flash the relock ftf via flashtool
2. Use sony Ericsson update to renew the whole system
I gotta say that the flashing over flashtool only works with the relock.ftf, every other ftf I have tried gives me Errors, thats why I use the SE Update tool to go back to stock.
I guess flashing a new kernel through fastboot doesnt work for me, maybe i can flash only the kernel through flashtool? Any suggestions?

Nobody has an Idea??? Plz tell me how you flashed your (working) kernel and which kernel to use.

Will, I have a problem like that but i can't flash any thing with fastboot (Kernal or system)
and i'm also looking for help.

Plz say what exactly you did, otherwise nobody can help :-(

Will, Check my thread for details: Here

ddsds Just a thought, you could try relocking and unlocking bootloader again, maybe fastboot will work better

Wouldn't recommend you try it on a locked bootloader.
Those that are unlocked shouldn't have any issues.

Technically, with a locked bootloader, if Fastboot will allow you to downgrade, then it should be possible.
You'd have to boot into Fastboot, then run the command:
fastboot flash system system.img
Where system.img is the 4.1.2 image file extracted from the fxz file. If it won't let you do this, then downgrade isn't possible. It will likely say failed flash and you'll have to flash something to kick the phone out of fastboot like logo.img.
You could also try RSDLite and try to flash the 4.1.2 fxz, but I doubt that will work because bootloader and such are not downgradeable and it will likely fail.

You can get them here:

You can extract the original system.img from the archive as well as logo.img in case the phone doesn't allow you to flash system.img, you can use logo.img to kick the phone out of Fastboot. You will need to install Motorola ADB drivers on your computer in advance, and also need a fastboot.exe file which I think you can find via Google, but if you have ever rooted your phone in the past, usually that also came with fastboot.
Anyway, get into fastboot mode by turning off the phone, then holding down all 3 buttons. Use vol- to select Fastboot and vol+ to choose it. Phone should boot into fastboot.
Connect to PC and issue command:
fastboot flash system system.img
If it works, the phone should be downgraded. If it says flash failed, then downgrade isn't possible. In that case, if the phone is stuck in fastboot mode and can't be rebooted, issue this command to get out of fastboot.
fastboot flash logo logo.img
That should let it reboot as normal.
I actually doubt it's possible to downgrade, but I haven't tried it myself so I can't say for sure.

Thank u so much my friend, I need to clear that I m using this phone in India with Reliance CDMA network. If downgrade will succeed then will it in verizon locked condition or it will remain unlocked for global use? Also I need to add that I have never unlocked my bootloader or rooted my phone.

I think it would stay unlocked since you wouldn't be reflashing the radio.
It is easy enough to re-unlock if that should get reversed, however.

Ah, nevermind. Don't bother to try it. Even if you could succeed, you'd end up with black screen after the logo. The newer bootloaders will not allow Jellybean to boot. There is no way to downgrade. KitKat is a one way road with a locked BL. Sorry!

Good news is that major developments happened a month ago. :good:
You can now root AND unlock bootloader on KitKat. I think you can find the info you need in this thread:
http://forum.xda-developers.com/showthread.php?t=2783806
Once you have bootloader unlocked, you can downgrade back to JB. I have tried it and can confirm it works.

You just run it and let it do its thing. Your phone should be rooted once it has rebooted. You can verify with any rootchecker app.
Then install and run Motopocalypse.apk to unlock your bootloader.
You can the use RSDLite to flash back to JellyBean using the JB fxz file. You will need to edit the xml file in the fxz file, removing the lines with gpt.bin and tz.mbn.

[Q] bootloader issues

So a while ago I rooted my phone but messed it up because I uninstalled a few too many system apps. I just dealt with it for a few months since I could still make calls (but not much else). I finally bit the bullet to look into flashing the stock rom again, but to do so it looked like I had to install a custom recovery, but to do that, unlock the bootloader. So I first unlocked the bootloader using motopocalypse (batch file didn't work but apk did), and got the expected BOOTLOADER UNLOCKED message at bootup, with fastboot saying unlocked, code 3. I then tried flashing CWM recovery via Rom Manager, and it seemed successful, but I was unable to boot to it either from the UI of ROM manager or from holding the buttons during bootup, it would just hang for a few more minutes than normal at the BOOTLOADER UNLOCKED screen, then boot up like normal. So I kept reading, found RSDlite, and was able to flash the stock rom, which I downloaded from the internet and the phone boots up fine, but now fastboot says locked, status code 2, and motopocalypse does not unlock it again (either the batch file or the apk), but I still get the BOOTLOADER UNLOCKED message at bootup. So I'm not sure if my bootloader is unlocked or not and if I can proceed with installing CWM recovery again, so i can make a full backup in case I mess something up again.
So how do I reunlock the bootloader, or verify if it's locked or not?

First, CWM and TWRP aren't official for this phone, so you can't use their apps to flash. You'll need to use fastboot, Flashify, or Rashr. Second, you're still unlocked, we've seen this error come from bad flashes. What is the complete text on your FB screen. You should be able to clear this by re-flashing with RSD. What firmware did you attempt to flash?

I think your boot loader is still LOCKED. Mine is showing UNLOCKED. Status code: 3. You cannot flash a custom recovery on a phone with a locked BL. You need to motocalypse again!

To trace the issue from the ground up, if you're just trying to reinstall stock ROM, you should be relying on RSD instead of trying to mess with custom recoveries and BL unlocking. Just flash .10 (not .15) via RSD, root via Towelroot and you can start fresh.
Unlocking your BL is still highly recommended, though, 'cuz it's now or never.

Yes, that's why I'm asking. So I've got one vote for unlocked, one for locked. As I said though, motopocalypse isn't working a 2nd time.

I would like to flash custom ROMs later down the road, but for now I just want to get the stock stuff going.
On a side note, the version of the image I downloaded was 183.x.x, but my mother, who has the same phone, purchased at the same time, and has never rooted it or anything, has version 182.something, and that is also the version I had before I started messing with the bootloader/recovery stuff. The two versions were released at the same time, but I don't know what determines which version you got if you just did OTA updates, or if it even matters. Speaking of OTA updates, the version I downloaded is prompting me to do an OTA update now to another 183.x.x version. I wonder if I'd be able to grab the 182.x.x ROM from my mom's phone without rooting it via fastboot or something.

The 182/183 does not matter regarding root/boot loader unlock its the .10/.15 that matters do not take the .15 without unlocking your boot loader....
We cannot teach people anything; we can only help them discover it within themselves.

So no other thoughts? What would happen if I flashed a custom rom/recovery with a locked bootloader? I tried flashing the ROM again and fb still says locked, code 2, and motopocalypse still doesn't do anything like it did the first time.

It won't let you flash a custom recovery. This is the difference between locked and unlocked.

If your bootloader is relocked for some reasons, try unlocking it again with

fastboot oem unlock

I guess what I'm asking is, will it let me flash it but then the phone won't work or will give an error on boot, or perhaps brick my phone? Or will it just not flash in the first place? Because if it's the latter, then I can just try to flash a custom ROM/recovery and if it works then I know it's unlocked.

Still locked code 2 though. Looks like it wants an unlock code from Motorola's website, I tried following the steps to get the code but it says I'm not eligible for bootloader unlock. So unless there's another way to get the unlock code...

A "Code 0" locked device would refuse flashing an unofficial or older recovery. I have no idea about Code 2 though.

From what I was able to locate status code 2 indicates that the bootloader has been unlocked and relocked like by doing the whole "fastboot oem unlock unlock code" then the "fastboot oem lock" ... I'll look more into it but from what little I read it looks like it can not be unlocked again with out the Motorola unlock code...

Same here, I can see what it means but cannot find any way to get back to code 3 other than using the unlock code from Motorola, which I am unable to obtain because it says I am not eligible. Surprising that someone hasn't cracked the unlock code yet or made a keygen, people are so eager to do it with pirated computer software before the software is even released.

I've read of someone getting locked status code 2 b4 from flashing an older gpt with rsd (if I remember correctly) I think all that was required to fix it and get unlocked again was to flash the latest gpt. Very important..... Are you sure when you were unlocked you didn't ota update to .15? Because flashing .10 gpt while on .15 may be what caused your false relock

Nope, no OTA update to .15. The ZIP I have of the rom does include the gpt.bin file with the same timestamp as all the other files. I suppose I could try reflashing the whole rom once again later...

Hmm strange, I went to find the old thread I read about the gpt relock issue but it's not exactly the same as your situation.
http://forum.xda-developers.com/showthread.php?p=51436123
Until now I didn't think relock was possible due to the way unlocking works. It's a physical change, a qfuse was blown when the motopocalypse apk was run the first time. It can't be unblown lol. Wish I knew what went wrong here.

Huawei p9 hardbrick, cannot resolve the problem

Hello mates!
Yesterday I accidentally bricked my phone and I spent ours and ours on this and others forums to find solution but without succes, so here is what was happen:
I was on L21C432B380 firmware, stock, bootloader locked, without root acces. So I tried to flash ROM 7.1.2 AOSP by Meticulus. I followed step by step guide. I succesfully unlocked bootloader using fastboot. Then I flashed TWRP again using fastboot so I can downgrade to EMUI 4.X and that was succesfull also. After that I flashed oem-info using TWRP and flashed stock UPDATE.ZIP using three button method, both succesfully but when phone tried to boots up It shows message "No OS installed".
My entire system and data was deleted, there is no recovery, bootloader is again locked, I have only managed to get into fastboot mode using adb
Every single command I tryed to run in cmd results in this message: "FAILED (remote: Command not allowed)
Somehow I need to install Firmware using fastboot but don't know how cause bootloader is again locked
My knowledge about this things is above average but I cannot "google" the problem
Please help and thanks in adavnce

Hello man,
Dont know why u do that (downgrade to MM)...
Explicitly written for flash AOSP 7.1.2 to be on emui5 (were u was)...
Flashing oem also relocked your bootloader (written ton of times in threads)....
Now using fastboot re-unlock bootloader re-flash TWRP.
If u maked a full backup just use it, otherwise try to follow this guide..

I don't remember how, but a locked the bootloader and installed stock rom.. everything OK, but after an OTA update I got no bluetooth and I can't install now any other rom cuz I lost my OEM unlock code and now I can't get it from Huawei... When I go to fastboot, I have PHONE Unlocked and FRP Unlocked too, but I can't flash the recovery... it's like the bootloader is unlocked, but it don't let me flash my EliteTWRP image... I get FAILED (remote: Command not allowed)
Any sugestions on how to fix this? I want to give this phone to my nephew, it is still a good phone for some games and whatsapp
thanks :angel:

Hello,
even if it says it's unlocked, it's actually locked.
So you need to unlock it again if you want to flash stuffs...
Good luck
P.S.: About your other post... You cannot flash with dload method on android 7,
you need to use Elite recovery and HWOTA method or Huawei Recovery Updater to flash the firmware
you want. ( be sure you choose the correct firmware )
Cheers
