Black screen after kernel(s) flash - Sony Ericsson Xperia Neo, Pro

Hello
I hope I'm not making a double post or something...
So I tried to flash the alliance kernel, but got issues with it.
I tried the stock 1.4 full logo, cm9 full and lite logo
(found here: http://forum.xda-developers.com/showthread.php?t=1566871)
Each time, I got a black screen after 1st vibration at boot.
And nothing happens.
I tried flashing with flashtool and fastboot command line.
Same problem.
Hopefully, i can reflash the original kernel from original ftf file to make it work again, but why do I got this issue, as when I read all thread, no one got this problem.
ps: Neo V mt11i / 4.0.4 / rooted / unlocked BT

I think the newest CM9 is not compatible with the Alliance 1.4 kernel. The kernel is based on the FXP128 kernel. Try flashing the kernel from the cm9 zip.
Sent from my Sony Xperia Neo using xda app-developers app

Hmm maybe I explained wrong..
I don't want to install CM9 rom.
I just want to flash the alliance kernel (and after, maybe [email protected] rom)

how you flash kernel with fastboot command?please explain here what you have and what you do...

Ok let's try to explain what I did:
I first d/led stock 1.4 kernel (link in 1st post).
I used fastboot command line to flash it.
Flash in 1.9sec, all seems to be ok.
I reboot the phone.
Vibration and black screen.
Have to replace battery to reboot again.
But always the damn black screen.
Then I use flashtool to flash the official ftf file (431 central europe 3), but only the kernel and wipe cache.
Now the phone boot normally.
I tried the other kernels given on alliance post, but always the same screen.
After reflashing with flashtool my BL is locked again (damn it), so tonight i will "test point" it again...
And then, retry another kernel or this again if I found a solution.

My Bootloader didnt locked again after flashing FTF file with flashtool,how did u can lock again?
My BL will relock if i used restore button on S1tool...
try again till succes....

Ok, i think there was a mistake this afternoon, because I just check at home, and BL is unlocked, so all is good.
But!.. I just try another kernel (http://forum.xda-developers.com/showthread.php?t=1679771) and also with suave kernel, and guess what...
Black screen again...
I really don't understand...

Maybe your problem related to this....

thanks for answer, but I think i'm not concerned, because I bought my mt11i "naked", and the bootloader status says unlocking is allowed...
Is there another way (s1tools) to know if BL is unlocked?
(And now, I'm afraid to flash a locked BL custom rom for testing.. lol)

I unlocked my bootloader via test point. At service menu the status still says bootloader unlock allowed yes, also it is unlocked.
On my lww which I unlocked via official Sony method the status says bootloader unlocked yes.
When you are able to flash a custom kernel than you have an unlocked bootloader.

I wanted to tell you that i unlocked bootloader of both phones. From live with walkman and the neo v.
Neo v via test point. Service menu still says bootloader unlock allowed yes
Lww via SE Bootloader Unlocking Relocking 1.6 tool (equal to sony method). Service menu has changed to status bootloader unlocked yes
Link to SE Bootloader Unlocking Relocking 1.6 tool: http://forum.xda-developers.com/showthread.php?t=1560613
Both phones are unlocked and the status is not the same. neo v still has the same status before i unlocked it. i thought that it will change to same status as the lww.
But it's (neo v) bootloader is unlocked, because i could flash a custom kernel (night elf ics 1.4).

1. Are you sure your bootloader is unlocked, if yes how did you do it?
2. Are you sure you downloaded a working flash tool and installed all needed drivers?

hooo ok ok ^^
1. So yes, I'm sure BL is unlocked, I verified with s1tools and service menu.
2. I think flashtool is ok because I can reflash the stock kernel. But maybe i should check the drivers.

Really strange behaviour.
I never hat any problems like you.
1. Please take a screen from service menu with the status of your bootloader.
2. Tell us which method you used to unlock your bootloader.
3. Try again flashing a kernel and post us the log fron flash tool.

I just reinstall drivers and flashtool.
I tried to flash differents kernels but always this black screen.
To unlock BL, I used Testpoint Method.
Here is the message i got:
Code:
writing 'boot'...
(bootloader) Download buffer format: boot IMG
(bootloader) Flash of partition 'boot' requested
(bootloader) S1 partID 0x00000003, block 0x00000280-0x000002e3

(bootloader) Flashing...
(bootloader) Flash operation complete
OKAY [ 1.236s]
finished. total time: 1.919s
As you can see, there a strange thing at line 5...

Hi my friend.
Yeah, line five is the answer to all your problems. Bad blocks at the bootloader are worse. I searched a bit with the help of google and some german forums.
Thats what they wrote down there.
A bad block at a custom kernel results in a not booting rom, while the stock kernel results in a booting rom.
The reason they wrote at at german forum is, that the stock kernel detects the bad sector and marks it to not use it. That's the reason why the stock kernel ist still functioning.
I am no kernel technican and i can't answer you if you can repair your bootloader.
But it would help, if the programmer of custom kernels could also implement a routine for detecting and marking such bad blocks like a stock kernel.
Sorry for bad news.

Well too bad for me...
But many thanks for searching and finding a answer ^^
(I think I will stop my try for the moment.)
Thanks

Locked the bootloader again.
Will update if any problem occurs in usage or updating.
TESTPOINT method should be used very carefully. better to take some help from another person. when connecting or disconnecting of usb cable is required it should be done from pc, microusb should always be connected to avoid moving the phone while touching the testpoint.

I'm glad that this idea works, I also unlocked my bootloader the official way and loss the DRM, track id and OTA, but everything is working now, I got everything work a different way.
BTW you can relock the bootloader by flashing a ftf file, it doesn't matter how you unlocked the phone, just put the phone in flash mode.
Which file you flashed? I see that post but when i open flashtool and try to flash a ftf file there is no loader.bin only preset.ta appears i do not understand why but every time i try it's no loader.sin so i do not do it. Just use s1tool restore and reunlock with test point
I have a file called xperia relock bootloader.ftf, thats how i relock my bootloader before.

[XU] Huge Problems Xperia U

Ok guys, I'm in deep sh*t -- let me start off.
I have an Xperia U rooted and locked BL, ever since JB was ported I wanted to try it, so I unlocked my BL by this method using flashtool --
1. Install Flashboot and Fastboot drivers of Flashtool (setup file will be on C:\Flashtool\drivers or similar place).
2. Turn on your phone, and connect with usb debugging on.
3. Go to Plugins-> Bootloader Unlock option, start it.
4. Now it will ask to disconnect your phone and reboot in FLASHMODE.
5. Again reboot your phone in FASTBOOT mode.
6. It will show a window with your IMEI number, insert your unlock key and click "unlock".
7. The device will reboot and you are done!
Everything was fine, I rebooted my phone. Download music info was FCing and I knew this was normal coz we lose our DRM keys when we unlock BL (Right?) So, After I did that, I wanted to try out Sliding XU kernel for XU so I downloaded it and flashed the .zip via CWM. Now the problems begin -- My phone didn't boot up at all, no Sony logo nothing, just 1 vibra ( Soft-Brick right? ). That shouldn't have happened right? Coz I was bootloader unlocked.
So I got worried and thought of reverting back to stock, So I reflashed stock generic ftf via flashtool ( B.54 ftf ). I wanted to root and install CWN so that I could restore my nandroid backup ( Yes! I made a backup ), But now my phone wouldnt root! I tried binary's root ( any droid and nothing, no root! (Error was -- "RECONNECT EXTERNAL MEMORY & TRY AGAIN"). I couldnt install CWM either ( atis112's). I used that coz all this time I used mods made for locked BL, I didnt know which to use for unlocked BL (noob regarding BL).
Started getting even more worried, So i tried flashing a custom pre-rooted kernel, even that didnt happen via flashtool, Here the error was " Root Required" or something, dont remember properly. I thought once I unlocked my BL, I could flash any kernel without root! (am I wrong?).
I dont even know if my BL is unlocked properly or not, since there is no way to know its status. So I tried download music info via walkman, It worked! Isnt it not supposed to work? I did it till 1% only of 524 songs ( Bad data plan, couldnt afford to lose bandwidth )
Now i dont know what to do bout rooting, unlocking BL or anything, BTW the phone is fine with B.54 firmware, just no root. Please Help!
P.S -- Long post, but please take a couple of minutes to help me out, sorry and thanks
Sorry bro, lemme help.1 You have to do some wipes in CWM when flashing kernels. 2 You can't root B.1.54 unless you flash .10 kernel, root then flash 54 kernel. 3 Yes you need root to flash a kernel
Press thanks?

Ok, thanks for your help, but first things first-- need a lil' more help from you
1. How do I root B.54? You said flash .10 kernel, I've never flashed a kernel before and I don't know how to do it, so help here.
2. Is my BL locked or unlocked now? Any way of knowing its status?
3. Since .89 firmware came out recently, Isnt it better to install that rather than B.54? And the method to root it is the same right?
4. Finally, Is the method I mentioned earlier to unlock BL correct? Did I do it right?
Well you have to flash 6.1.1.B.1.10 in flashtool, exclude everyting except the kernel. Turn it on, enable USB debugging (everything will look weird) ,root it then flash .54 kernel in the same way
Dial *#*#7378423#*#* and go into customization. It should say Bootloader Unlocked: Yes
You can flash the latest, it is stabler. Root the same way.
Yeah, if it says you did it in service menu.

You did not unlock bootloader because you booted phone into flashmode.

After a few tries, I have found out how to boot into our phone's stock recovery. We are now one step closer to root and flashing new ROMs! I know all of us can't wait for that.
Edit (September 6): ROOT AND UNLOCKED BOOTLOADER ACHIEVED! Check out the thread here. If you need help, don't be afraid to post in that thread! We'll get to you ASAP.
1) Turn off the phone.
2) Hold the power button and volume +.
3) Once the Huawei logo pops up, let go of the power button but not the volume + button.
4) The recovery will pop up, and you can let go of the volume button.
It'll look like this:

Good Job
recovery ,root ,Roms its gonna be a long ride for mate 2
Scoob I really appreciate what you and Modding.My.Mind have done today.
We aren't there yet, but we're so much closer to root because of you guys.
Thanks alot.

Nice find! Just ordered one on amazon tonight. Cant wait til i get it. Ive been flashing phones since the OG evo 4G. Hope we see root for this device soon!
If I had this device in my hand I could tackle it personally. Unfortunately, that is not the case, but I hope you guys see root soon. Now that you guys/gals know about this feature on your device it is just a matter of signing the update.zip properly which I sent to @ScoobSTi a few days back. The updater-script is written so that it will work in a stock recovery but without an acceptable signature the stock recovery will sadly deny it.

Go ahead man, no problem. It's made public on my dev host account. I recommend you make a notice in bold red in case you get that one guy lol. A disclaimer of some sort for development purposes.

Thanks! I'll just attach it here haha.
For those that don't know: attached is the flashable ZIP file that Modding made for us. If successful it will grant us root permissions, but at the moment it doesn't work, because it is not signed correctly. If anyone knows anything about signing, please try and work your magic! :good:
Man, hopefully we will see root very soon.
I almost ditched the phone for a Galaxy S5.
Glad I didn't.
I'd much rather see root versus Kit Kat update.
Following is a little bit more info:
Confirmed this device (MT2-L03) bootloader is locked.
I press and hold "volume down" and "power" keys for more than 10 seconds, I got into the fastboot screen, it displayed that bootloader is LOCKED.

I'm curious, but could you try:
Code:
fastboot oem unlock
May or may not work, so it's an idea. Not all devices can use this directly without taking other necessary steps.

Hi Modding.MyMind, First want to thank you give us MATE2 forum your help, and that su binary flash zip. Unfortunately, I tried a tools called Auto_Sign, and also use my own key to sign, both zip cause "Installation Aborted".
That's why I post above locked bootloader info, but still due to my limited knowledge of Android, I am not sure the relationship between the root and locked boot loader.
I read some articles like this:
http://forum.xda-developers.com/wiki/Bootloader
http://www.xda-developers.com/tag/bootloader/
Those give me mixed info, I even see some phone can root first, then flash a unlocked bootloader.
OK, back to topic, following is the output:
Code:
D:\Android\android-sdk\platform-tools>fastboot oem unlock
...
FAILED (remote: Please input key)
finished. total time: 0.009s
And even tried a dummy unlocked code (this should be 16 digit as the huawei website example says):
Code:
D:\Android\android-sdk\platform-tools>fastboot oem unlock 1234567812345678
...
(bootloader) Unlocking ...
OKAY [ 0.018s]
finished. total time: 0.021s
But, no, its not working, the phone display "Invalid Key" and rebooted.
P.S., I am Chinese and own a different HuaWei phone before. The official way is to use their website to request the unlock code, Huawei will record your SN number, and give you correct key to unlock it. That's the reason I have sent email to them to see if they can support this MT2-L03 in their request page.
Actually I just own this phone a few days, and starting reading the forum post, I think "ScoobSTi" actually tried the unlock before with similar result.
Anyway please let me know if you want me to test anything else.
Thanks.
unlocking that bootloader could possibly make some of the previous root methods several people have tried actually successful.
Oh this is getting interesting. We seem so close.
For some devices unlocking the bootloader would allow installing root similiar to what I shared. For most, it isn't enough. For the majority out there it is likely that a custom recovery be available to successfully gain root (which in turn would require an unlocked bootloader). Each device is different in these cases. For my current device, an unlocked bootloader is required so that a custom recovery may be allowed to overwrite the stock recovery.
Though, I will say, that by having an unlocked bootloader, the possibilities will most surely increase.

This is a bit off topic here, but TWRP is built to root devices if one by chance is developed and built properly for the "given" device. Saves the hassle of having to make flashable zips lol.
I actually need to rebuild TWRP for my device . Just got to sync omnirom after accidently screwing up my linux system this past weekend.

Thanks for trying! We may finally be getting closer now. I'm seriously missing a lot of the root tweaks I had on my old phone.
Teeny-tiny update.
It seems Huawei has updated the Emui website, most likely because of the Mate7. It is now both in English and Chinese.
The bootloader unlocking website has also been updated in the same fashion. The Mate2 now shows up, but unfortunately it's the MT2-C00 version, not our MT2-L03/5. Hopefully Xordos's email will help!
Thats it....Bootloader is now unlocked !!!! and rooting is successful !!!!

[Q][Z2]Relock/unlock Bootloader

Hello.
I have wondered about unlocking bootloader and go over to CM on my Xperia Z2.
But before i do so, i want to clear up some things first.
Is there a way to relock bootloader on my phone?
Will I be able to unlock after I have relocked? (using official metod)
Backing up TA, will it store my DRM-keys and make it possible to get them back after locking bootloader again?
I want to do this because im currently using CM on my Mini Pro, and i want to try it on my Z2. And I want to be able to get back to stock when the L is out for Z2.
If someone can answer my questions, or point me to the right direction, I would be much happy.

1. Yes, using flashtool, other methods i dont know of
2. Yes
3. Drm keys are in TA partition so backup your Ta and restore later (restoring relocks bootloader so flash stock kernel before doing so)
4. Relocking bootloader doesnt bring back drm keys
5. Its safe to restore TA over a locked bootloader
6. You can only restore TA or relock bootloader on a stock kernel
Answers to your queries :
1) Yes, you can relock it once it is unlocked. Restoring TA partition will also relock your bootloader.
2) Yes you can.. You need to have the oem unlock key which you have received from Sony while unlocking for the first time.
3) Yes
Please read this thread : http://forum.xda-developers.com/showthread.php?t=2440597

OK, thanks for the quick answer.
Here is a short of what I understand now. Correct me if its wrong.
Using this tool, I can backup and restore TA.
When restoring TA, it will lock bootloader automatically.
To restore TA, I have to download and flash stock ROM for Z2 (Nordic in my case), and that should be ok to use XPERIFirm to download?
When done restoring TA, I dont have to do more than wait for L to come to me??
I hope this is right, in that case I might give it a try.
(I dont want to start something without planning a way out of it, thats why I ask.)

3. Xperia firm, you can use flashtool to bundle the files into a FTF or you can see if someome has done already here...

One more thing. The key for unlocking my bootloader, is it the same after locking it again???
Or do I have to ask Sony for a new one?

Have you got an idea how to enable double tap to wake?? Cannot find it anywhere.
if you have installed a custom rom like CM then the chances of the kernel not having the double tap to wake wont be there because its the kernel that will have it and not the rom . So if you do want it then you have to look for a kernel which has got the feature

After installing m5 kernel, download m5 kernel settings, thats how you enable double tap to wake
It should show an option somewhere in the device settings now

It depends on the carier and i do believe you can pay for sim unlock and a bootloader release

Already payed for sim unlock, the phone was locked to EE UK. Here's a SS to see what it says on rooting status. When i unlocked it, they provided me multiple codes, NCK, SPCK, NSCK, CCK. Is any of the codes for bootloader unlocking? If so, where do i type it? Cheers.

My Z2 should be here on Tues, and I was going to unlock the BL, the directions above are very clear and straightforward. (I had a TMO XZ w/ an unlockable BL, so I know how the rom flashing goes) My question is do I have to use Nutz recovery, could i just fastboot flash recovery twrp.img and use Team Wins? Also for flashing a ROM do I need to use the FFT or can I just flash a rom the more traditional way say like a Nexus device? Thx guys, Im very green when it comes to Sony. Nexus, HTC, and Sammy are my staples. Thx again.
Nut is mainly for locked bootloaders, once you've unlocked the bootloader flash a kernel such as dooms via adb then flash a rom from recovery ftfs are stock roms only any custom rom will have a flashable zip

So you can unlock the bootloader, then relock it, restore TA partition and it will be like you never had unlocked the bootloader? I mean, if you do that, your device will be able to recieve OTA (and all Sony's features like x-reality and better camera performance) and your warranty will be "restored"?
