Help - I cann't install custom rom on my x10

Hello everyone, I would like to have some help about installing custom roms on x10 devices...
Being honest the one who has the problem is my friend, he's in México using a Telcel Xperia X10, and we did all the steps for rooting the phone and so on.
The phone has already superuser and xrecovery, but when we try to put custom roms for locked bootloader always obtain the same line "Installation aborted". Of course we follow the threads abouts roms but nothing....
I don't know why this mistake?? Did anyone have the same problem??
The phone: Android 2.3.3, baseband 2.1.71, compilation 3.0.1.G.0.75....
FlashTool_0.2.9.1
Trying to install XSP rom for locked bootloader
Please if someone has a solution I would appreciate it so much or send me a PM...
Thanks.....

Hello , I guess you are getting the error because you are using rom.zip for unlocked bootloaders . Make sure you are using the correct zip file .
Or else you can unlock the device via latest flashtool (Flashtool in X10i developement section) then proceed with installation . It should work .

I'm very sure that the rom I'm trying to install is for locked bootloader even unlock the boot wasn't a solution...
i think you can check the information book first, to make all things right, if can not find it, try internet.
You can find all useful things through this, then make your phone good, Good luck.

[Q] LG Optimus L5 E610 reboots bootloader

Hi guys. Last night I tried to unlock my E610 bootloader, flashing recovery and eventually flashing with new ROm, but after I followed the steps for unlocking - I got a problem. My phone restarts after every Multimedia scanning. Although I can get to Recovery menu. I can put custom ROM in my SD Card and eventually flash it by Recovery menu, but would it fix rebooting the phone? And if it is - how to do that.
Please, I need your help!
p.s. I didn't make stock bootloader backup

I have a e612f with the same problem.
I did the same commands but with other bootloaders and recovery. I think it is previous version of the bootloader. I can send you, if you want. Also now I have a backup of stock bootloader, if someone need it.
Tonight I can put the in here, if you want.

No, I unlocked E610.
i did the unlock with the file for the 612 but it keep restarting
my LG is the e612g..
any help? for unlock the L5 e612g?
My problem looks like this:I have installed custom ROM on my LG L5 i think its mod of stock 20c (not sure) it work very gd,it has OC kernel on 1Ghz and its very fast and smooth.Battery life is better then the stock.In settings/about phone it says JB 4.1.2.What happend:I tried to install chainfire 3D and suddenly i lost Super User permisions and my phone restarted it self.After 2 hrs of war i managed to get into download mode n usin KDZ i flashed stock firmware or i tought it was a stock ICS.Well its not.It stayed on JB 4.1.2 and i cant get into recovery.Tried to root it but no luck.I cant use Titanium Backup to make few backups and to try to flash it again.Any help from here?Readin the posts on this topic it looks similar to my problem i cant get into recovery,cant root my phone.... -.-
Does anybody know how can I backup my stock bootloader? I want to unlock my bootloader, but since I keep seeing problems with random rebooting afterwards, I would like to do some preparations in case something goes wrong... Also, I read tons of explanations how to solve that problem, but I'm still not sure if I'd be able to do it...

Camera's not working after unlocking bootloader.

Hi guys,i realy love to flash a custom rom in my Zenfone 5.
Yes,I can flash roms or whatever via recovery,the only real problem here is,when i unlocked the bootloader,the camera will not working either on stock rom or custom rom,others are working just fine.
Flashing custom roms sure are fun,but this issue gave me a huge bummer as camera is realy important.:crying:
I used alot of methods to unlock the bootloader,but the problem still remains the same.:silly:
My Zenfone 5 Model is A501CG,here are the specs :-
-2/16gb ROM
-Intel Atom Z2560 1.6ghz
I found out that they are few users that having the same problem as mine.
Don't worry,i can make the camera back to normal,but for that,i'll have to relock the bootloader
I hope the devs will work on this problem.
Thank you and sorry for my bad english
You might have done some thing wrong or used the wrong unlocking tool am using same device with RR and camera works fine. try https://drive.google.com/file/d/0B-Fin8UxrD6PRU9MM1lQZkV0SG8/view
this is what i used and its works fine!

It's a uncommon issue that I found too.
Unlocking my friend's phone EXACTLY same way I did on mine (40.30 bootloader, 59.A1 ifwi) made his phone camera stop to work.
I don't know what is the issue, but it makes impossible to use the camera on the phone with a unlocked bootloader.

I'm on kk 2.22.40.54 original firmware with root and locked bootloder (i tried to flash twrp but the process failed). Can i use your tool without problems like random boot, no camera, etc.?
I need to install custom recovery only.
How can I make system backup before?
Thanks

You can try it. There's a small chance of your phone bring different from ours (which causes the camera bug). If you get camera bug just relock bootloader.

You can't install twrp with lock bootloader, you can't unlock den you can't , bad luck for you . If you want your phone to look good then try installing Xposed and mod it yourself

Bricked Huawei Honor 8 Lite PRA-LX1 | No Recovery | No OS | Bootloader Unlocked

I don't know what to say other than what I've did... I've unlocked the bootloader with an official code from Huawei, then I followed a post from Gizdev (dot) com on how to root the phone and successfully installed TWRP and root. After that I've downloaded a couple of system app remover apks and I've deleted something that made the phone go into bootloop so I've searched and downloaded different ROMs for hours, supposedly for this phone and it always gave me Error 7. I've tried to fix it with Notepad++, it apparently worked but then the ROM did not boot and after many hours I've repeated the process from the post but instead with a ClockworkMod recovery and that was the dead end.
For those that might be stuck in the same situation, I've found a way to get back to fastboot mode with the "finally-how-unbrick-revive-hard" tutorial from nairland(dot)com and MEDIATEK VCOM DRIVER. Then the "Root Honor 8 Lite EMUI 5.0 And Install TWRP Recovery" tutorial from Gizdev(dot)com to get back TWRP.
So after many many hours of agony, I've managed to get it up and running with an "elite" rom from HassanMirza01 BUT, IF you own a Honor 8 Lite DO NOT touch it, just leave it as it is, it's not worth it AT ALL... If you don't like the bloatware or the ROM just sell the phone and buy a different one, for real. The moral of the story is: Huawei SUCKS!
HELP
