Hi everyone,
I've got a quick bootloader unlocking query - if I were to unlock my bootloader and then immediately flash a custom kernel (i.e. no reboot in between), would this cause a hard-brick?
I ask because I'm on my 2nd phone now, having bricked the first one due to impatience! I'd like to unlock the bootloader but I'm too scared of bricking it again :silly:
Cheers
im quite sure you may need to let it settle for a bit
there has been no one who i know of who has done that so id suggest of unlocking and waiting a day or two

I think you'd better read carefully in the furom,unless you are full understanding,you can flash the custom rom

Yeah I've done a lot of reading & following guides for rooting etc. I've been searching through the bricked devices threads and it has now put me off unlocking the BL :laugh:
I found this post (http://forum.xda-developers.com/showthread.php?p=48773344#post48773344) where someone has successfully unlocked their bootloader and flashed an advanced stock kernel, and then flashed the DooMKernel (same one I tried the first time) and then bricked their phone!! Their symptoms are exactly the same as mine. The annoying thing is that everyone else seems to be able to flash the DooMKernel without issue - the DooMKernel thread is full of satisfied customers! The randomness of bricking isn't worth the risk
Cheers guys

well, this is my person experience, i unlocked and loaded a custom ROM immediately without flashing the kernal and it works fine. I am not sure if flashing a kernel after that will create any issues.

If you flashed a custom rom that required an unlocked bootloader, then I assume it's because it comes with a custom (i.e. non-stock) kernel? After unlocking the bootloader, did you let the phone boot normally before flashing the custom rom?

Yes I did... I asked the custom rom had a custom kernel inside

Ah, so you managed to flash a custom rom/kernel without rebooting after unlocking the bootloader? At least that confirms that something else is responsible for bricking my phone. When I bricked my phone, I didn't wipe cache or dalvik - I started from a fresh stock rom...didn't even root or have a recovery installed.

Hey guys,
since i flashed back to and older version to root the phone and then upgraded again, everytime my battery is empty and i plug in my phone in to charge, it ends in a bootloop. But when i press the back button to get into the recovery and then boot the phone from there it boots normally.
Someone knows what went wrong, when i rooted my phone?? :good:

here is a list of ROMs for your phone be sure you have Xperia Arc S not other phone never flash a ROM that is not for your phone because you can cause hardware damage to your phone
i cant install a custom rom, cause my bootloader is locked.
edit.:
can i install arconium (http://forum.xda-developers.com/showthread.php?t=1565475) cause it only requries a "stock kernel with CWM???
A unlocked bootloader is only usefull to install other kernels, but because this rom is compatible with a stock rom, i think i dont have to unlock the bootloader, right? :cyclops:

It seems Acronium requires an unlocked bootloader
for your first flash I recommend to install a stock-based ROM just leave bootloader as it is if you just wanna do this way then use a laptop when flashing /unlocking bootloader cause every failure in bootloader results in a dead-phone then only service tools save your phone -your phone is bricked
so search in that list for a ROM that is stock-based choose one with good howto instructions

I am pretty new to flashing ROMS and rooting. I rooted my S2 back in 2011. but since then I haven't. So i though I would do it with the Xperia S.
I installed XTXperience 9, unlocked bootloader. rooted n fastboot. I downloaded cwm recovery. cleared everything. installed the ROM, and It has got stuck in boot loop.
I was on the 6.1.A.2.45 firmware if that helps?
could someone please give me some short instructions and tell me what I am doing wrong I need this ROM looks so cool!
Please don't bite my head off either. I need help. it's only way i'll learn

If you have unlocked bootloader, why don't you install a custom kernel? Like Advanced ICS Kernel, ELiTE, etc.

Not sure how to do that yet. would that possibly fix the boot loop I am having??
I've never installed a recovery manually, because I've always flashed a custom kernel with a recovery included, maybe that's why you're having a boot loop but I'm not sure.
If you already unlocked the bootloader you should flash a stock based kernel and that's it.

I unlocked the bootloader before it got in the bootloop. after flashing firmware I guess it is still unlocked. just need to root it again
If you already have you bootloader unlocked just flash a custom kernel! If you flash a ROM after that, it will be pre-rooted.

My phone is a Xperia Arc (also known as lt15i) and it is rooted and has an unlocked bootloader.
It runs on Android 2.3.4.
I wanted to install CWM, and followed a guide for that.
Since I can't link the guide, I can just say that it's name was "How to root sony ericsson xperia arc lt15i and install custom rom" and tht is was on listenmefirst.
From that guide, all i did was option 2 for installing CWM.
At the end of the guide, it says "reboot your phone", and I did, and now it's stuck in a boot loop.
I've tried several different keycombinations without anything happening (holding down volume / holding left and right buttons / holding home+volume up). It does however blink a blue light when I hold left and right button, but it seems to have no effect.
So my question is: is there any way to get out of this bootloop?
if you have an unlocked bootloader you can simply flash a kernel that has CWM though fastboot or flashtool
Since your on 2.3.4, this may sound obvious, use a gingerbread kernel.
I used this for pretty much all GB roms i used

Then you need a kernel that supports ICS.
there's no possible way for me to brick your phone if you already have an unlocked bootloader. You can wipe everything off and start over. Everything can be solved.

If you just wanted to get out of the bootloop (like your title lol) then you need to flash GB kernel.
If you want to go to ICS you need to put an ICS ROM onto your SD card, flash kernel, then install rom
Thanks for the help, got it out of the bootloop today with flashtool! =)

hi,
after spending a lot of time in the KitSlim thread i'm getting more and more confused.
One person says do it that way, another suggests a different approach.
i'd like to install the KitSlim Evo9 from this thread:
http://forum.xda-developers.com/showthread.php?t=2743177
I'm currently running a stock 4.4.4 rooted with locked bootloader and a dualrecovery on my Z1C
- boot in TWRP
- do all the wipes
- flash the Rom from SD1
- without reboot flash the gapps
- power off
- use the flashtool to flash the 108 NUTStockKernel
- reboot & done
My Questions so far:
Is this order correct?
does the Rom file need to be on the internal Storage or would the SDCard also work?
Is the NutStockKernel ok for my locked BL, or do i just need to flash a standart 108Kernel file?
(Some say the NutStockKernel is only for unlocked Bootloader, some say it's for locked BL)
Does this NutStockKernel come with a dualrecovery?
Some even suggest not to flash a Kernel because i'm allready on a 4.4.4_108 !?
thanks in advance for answers!
the more i read here the harder it seems to get ^^ but i'll try.
this is a great community!

This is the process I used, worked fine.
thanks for the reply. i'll give it a go then.
If you already have fw.108 on your phone, you don't need to flash NUTs kernel.

does that mean, that the dual recovery will still be there?
(as far as i understand the recovery is in the kernel)
or does the recovery come with the ROM? cause it says in the thread that dual recovery is built in

Recovery is built into the rom, so whatever you do don't flash nuts recovery again after kitslim or you'll end up in bootloop and have to start from scratch flashing a stock rom.
So coming from a stock rom fw.108, with root and recovery (but locked bootloader) go into recovery, wipe system wipe cache&dalvik (don't reboot) flash the Evo9 then the Full gapps, that's it.
Even if it goes horribly wrong, you still won't unlock the bootloader, and rebuilds are so easy now thanks to Easyroot
thx for the advice. i did it and it's running on my phone now \o/
runs great, and no bugs encountered yet!
still got some questions.
are there any restrictions to what software to install with KitSlim running?

I think you should head over to the KitSlim thread, but no, it's just the same as a stock rom, install what you like. Although pay attention to which modules you install with Xposed, as some of them can clash.

Hi everyone!
So after unlocking my bootloader following Sony's guide, I restarted the phone but it got stuck in the bootanimation. The good news is that I had flashed CWM, the bad news is that the phone still gets stuck on the boot animation even With the Official CyanogenMod 11...
I really don't know what I must do and I can't find something concrete about my problem.
The bootloader can be unlocked, I've tested (with the code) before attempting anything. I have also the 4.3 update and followed a guide. I did flash the boot.img via fastboot. That's it. And the Xperia M I'm owning is a C1905.
I hope you people can help me, thanks in advance !
This happened to me the other day. Just reflash the 4.3 with flashtool, it will fix the bootloop. After that you can do whatever you want. Here is a link to download the stuff you need:
http://xperiafirmware.com/8-firmware/40-sony-xperia-m-c1905
Cheers
First of all use questions and troubleshooting section... I have to report the thread to be moved.
-
Second of all you do not have any problem.
The point is that you unlocked the bootloader while you have a rooted modified rom, right?
So after unlocking it do a factory reset, and due to modified system partition you are stuck on boot screen.
The solution is very simple, use flash tool and flash android 4.3 tft.
Then start your phone and make sure it boot up at least one time on stock firmware before starting with cm11 flash procedures.
Good-luck.
