Returning to stock rom and kernel - XPERIA X8 Q&A, Help & Troubleshooting

I haven't been on the forum since a few months ago, cause I got a new mobile, and I forgot a few things about x8. I have alfs kernel on it, and gingerdx, but i want to return to stock rom and kernel, and lock bootloader. Can somebody please post me a link with tutorila, because I can't find it, or tell me how to do it? thank you.

I can't flash stock kernel with pcc, I click on repair phone, then after downloading and preparing it just turns off. And nothing happens.

SEUS, but i successed, i just have to relock bootloader..

please help me! bad flashing? phone bricked?

Hi, I'm new in this forum, this is my first post, sorry for my english, i'm working on it, so, expect some bad errors...
Unfortunately it seems to be that my phone has been bricked... From the beginning i used the custom rom Ginger DX with stock kernel, then I decided to change and test the MiniCM of Nobodyatall. So, the first thing I decided to do was change the stock kernel to the custom kernel of naA (naa-08b), then I tried it with Ginger dx, after confirming that the rom and the kernel work, I decided to change the rom to MiniCM. with horrible results, I noticed that the phone did not pass the logo screen of the brand (Sony Ericsson), this means that the bootloader does not work no longer, that makes it impossible for me to change the ROM, thinking that perhaps the kernel generates me all this problem, I decided to change it back to the stock kernel, but without good results ...
I dont know what to do!
things that i noted while i was installing the custom rom:
-it said that i've didin't installed the naA kernel, wich it's not true, because before Install the MiniCM, i've flashed the cellphone with Flashtool, to install the custom kernel (which it worked for me, using gingerDX), so , maybe i didn't installed it right, or even it was never installed, i really don't know...
Please help! thanks a lot for your attention and any kind of help would be awesome...

Wrong! If you still see the Sony Ericsson logo this means your Bootloader and Kernel is still intact. If this wouldn't be the case you would have a hard brick (no lights, no vibration, no screen) on your hands.
To get your phone back into a working state ...
Flash back the ORIGINAL 015 BASEBAND (also includes the Stock Kernel)!
Baseband 015 for the X8 E15i (Flashtool FTF)
Baseband 015 for the X8 E15a (Flashtool FTF)
Do NOT Flash the wrong baseband - otherwise you may have problems connecting to the mobile network.
RELOCK the BOOTLOADER!
Do NOT miss out on the two steps above!
Flash back to Stock and go again from there
Hey! Thank a lot for the answer! It was very fast
so, if my phone is not bricked, that means that it can be fixed! thanx alot... what a relief, i was very scared!
okay, the thing that i've done right now, it's the downgrade of the baseband from 015 to 006 (my model is the E15a)... i noticed that , it's a wong step.. do i have to flash again to the original baseband 015?... i've downgrade it because my idea was to get the phone to the original baseband a kernel that it had when I purchased it, so the next step was, with PC Companion, repair the rom, to get de original one (2.1), the problem is that the pc companion didn't fix the issue because i't said something like " there is no update for your phone"... so, I'm at the beginning of the problem ... again ... :S
in another thread i saw this post made by you...

Yes, you need to flash the 015 baseband ... 006 is outdated and does NOT work with any custom ROM you may find around here in the Developer section.

The 006 Baseband (and possibly some 2.0 or 2.1 Stock ROM) may have been the default at the time you bought the phone, but meanwhile the latest ones are Baseband 015 / Stock 2.1.1.C.0.0 (X8 E15a/i) and Baseband 015 / Stock 2.1.1.A.0.46 (W8 E16a/i <-- is there actually such a thing as a E16i? Never saw one). EDIT: Don't expect to see any more updates from Sony Ericsson, the software update support for the W8/X8 phone is already discontinued for quite some time.
Anyhow, the "There is no update" message is a result of your alterations. Once you're running a custom Kernel or trying to restore from a soft-brick situation where there's still a custom ROM in the NAND (the Flash memory) PCC will most likely tell you to take a hike as it fails to correctly identify the phone (hence why I said "forget PCC/SEUS" in the post you refer to below). EDIT: Let me rephrase: "...as it fails to correctly identify the software installed on the phone as it's not a genuine Stock ROM, or Kernel"

It's the same thing I wrote up on my (still at being populated with content due to lack of time) droppage site ... the post on my droppage is just a somewhat rewritten version of the forum post to iron out things I missed to consider.
Both posts should work for you once you flashed back to Stock Baseband/Kernel and relocked the bootloader.
last question,(just to be secure of what i am going to do) how do i know if my phone has an unlocked bootloader? the only thing that i remember that i've changed on the phone it's the baseband, install xrecovery and clockwork mod, also the roms... i dont remember anything about unlock the bootloader...

At least you wrote in your first post that you installed nobodyAtall's nAa Kernel - which requires you to unlock the bootloader; otherwise MiniCM7 doesn't boot up... ... ... ... wait a sec ...
On a second thought ... could THAT be the reason why you're stuck at the SE Logo? You didn't unlock the boot loader, you didn't flash the required kernel for MiniCM7 but you actually flashed the MiniCM7 ROM and therefore managed to soft-brick?
About the question: See this thread. There's also a section about how you can tell if your boot loader is unlocked or not.
If the thread looks awfully familiar to you then you already dealt with boot loader unlocking. If that thread is news to you then you made a bad boo-boo along the way.
HAahajajaajaajahaja... Oh my gosh... that's totally not the answer that i was looking for... now i'm thinking "what the f*** did i done with my cellphone?", i feel really dumb right now, it's so much easier install custom roms with the stock kernel, but, well.. sometime's that's the way to learn new things, just messing up BADLY the things...
Oh god, well, this soft brick it's a huge pain in the ass.. so.. let's see...
i just wanna fix the phone, so, which are the best and safest way to fix it, considering that i've didin't unlock the bootloader? i dont wanna use the MiniCM7, i just wanna see the xrecovery to install any rom that work with the stock kernel, (or at least, anything that can keep running my cellphone...)
By the way... THANKS A LOT FOR HELP ME, right now, you are the only person who helped me , without your help, I would be totally crazy, hysterical, and angry ... even though my phone is not repaired (yet), you had helped a lot, sincerely, thank you very much!

This wasn't meant to make you feel dumb or bad ... the idea that you may have missed to unlock the boot loader and install the required Kernel just jumped into my mind while I typed the reply.
Let me tell you this to make you feel better ... if you look around in the "Q&A" board here you will notice that you're not the only one who managed to soft-brick while trying to install MiniCM7.

Well, if you really managed to downgrade the baseband to 006 then you need to upgrade it to 015 again FIRST (the 2.1.1.C.0.0 Flashtool ROM image needs baseband 015 ... only the older 2.1.1.A.0.0 stock ROM would also boot on 006).
You can find the baseband FTF either here in the X8 Development board ... or simply go to my droppage and click the "Downloads" tab ... the baseband FTF's for the X8 E15a and X8 E15i are for download there.
Once you verified that you're running the right baseband simply continue with the "Flash back to Stock" guide (Post #2 above) to pull your phone back out of Valhalla.

Question about rooting and install custom rom.

Hello all!
I'm new on this forum. I have questions about Xperia X8. About 1 week i will buy xperia x8(with android 2.1). I want to root it. I have found tutorials on net but i don't really understand, am i going to unlock the bootloader if a root my phone and install custom rom(I'm thinking to install Froyobread)? I don't want to brick my phone so is it safe to root? Also if i have Custom Rom(Froyobread) can I use market to install free apps?
Thanks
P.S Sorry for my english
rooting is easy. just use superoneclick. bootloader unlock is more difficult and dangerous.
for froyobread you wont need a custom kernel. you can us gingerbread roms 2.3 to without flashing a kernel. i have locked bootloader too.
It's safe to root your X8, i recommend this program to do with: http://forum.xda-developers.com/showthread.php?t=803682
It's a very simple and great program. U just need to connect your phone with USB Debugging, and click on root. Thats all
If you want to change the stock kernel (most of roms can run with stock) u will need to download stuff, and make these steps. http://forum.xda-developers.com/showthread.php?t=1254225
Also, make sure, your phone is able to do these processes.
And If you have a costum rom, you can download free apps from market. It's very simple.
To install a costum rom, u need just to read a lot of about it.
Good luck!
If I helped, please click on the THANKS button
magyarlovag
So that means with rooting i won't brick-damage my phone(if a follow instructions carefully)? What 2.3 android Rom to choose for daily using?
Will froyobread run on stock kernel(will i need to unlock bootloader)? Also is there a tool so if a brick(damage) my phone to restore to old state(i have heard that Sony PC Companion is doing that)???
Sorry for stupid questions
Every rom have it's own advantage. I'm using now Alfsv8 kernel, with GDXv22.
It's a very good rom, for almost everything. But nAa's kernel and rom are very popular and great too.
Rooting is very simple with this program, you can't miss it
EDIT: Most of GingerBread roms require the latest nAa kernel, but I prefer Alfs As I mentioned, u must unlock your bootloader to flash a costum kernel.
And yes, you can restore your phone if u accidently brick ur phone. You can make the restore with PCC.
So if i want to install froyobread i will need to change kernel. Is kernel automaticly installing when i browse and choose to install custom rom in xRecovery 0.1. Or is there a special procedure for that?
No, it won't get installed with a rom automatically (it would be too simple )
http://forum.xda-developers.com/showthread.php?t=1254225
Read this thread carefully, and u will know how to do it.
Wait but luisniklas said that i wont need custom kernels for froyo. I also read tutorials for installing custom rom for froyo and i don't find anything for custom kernels. I don't really understand is there a difference between bootloader and custom kernels? If i need to change kernel, i'm not going to risk my phone at all.
Sorry I'm so boring but i really don't understand this things
Update: I found that Froyobread is going to work on stock kernel? Is that mean that i have to skip that hard procedure(changing kernel)?
Some rom will work on stock kernel. I dont know which ones, minicm, gingerdx and the other better roms need to change the kernel. If you don't want to change the kernel, u will need to test the roms by yourself. With stock kernel, maybe u will have wifi, notification bar, bluetooth, camera, fm radio and other bugs. The performance will also won't be fast.
Thanks for explaing that. Now if someone know answer me:
WILL FROYOBREAD WORK ON STOCK KERNEL?
Look.I'll make it as easy as I can get:
First,you root.It's simple, easy and safe. Search for instructions about SuperOneClick.
Then, you install xrecovery.This is necessary in order to install rom.
Then,you choose the rom you want to install.Every rom mentions if it runs on custom or stock kernel, or both.
I suggest since you are new, you should not try to unlock your bootloader yet, you don't want to end up hard bricking your phone.
Go to the rom you want to install, and see if it says stock or custom kernel.And then, you save it to your sd card, you go to xrecovery and install it.
I found this http://forum.xda-developers.com/showthread.php?t=1079463
There is nowhere said that this rom need stock or custom kernel. What will happen if this rom needs custom kernel and i have install on stock?
After you install it, your phone will be stuck in the Sony Ericsson logo. That's what happens.

I want to be safe, so I will make a backup of stock rom in case this custom rom not work. I'll make backup and then if get stuck on sony ericsson logo i wall restore to stock. Anyway thanks guys for explaing me, if I stuck on some steps i will ask you.
Edit: Last stupid question: So if this rom work on stock kernel i won't need to change kernel or unlock bootloader?

Yes, that's what it means.
No, you won't.
But after u learn things about the X8, u should change the kernel too.
install recovery after rooting. use the xrecovery installer. if you cant find it pm me and i will help you. in xrecovery you can backup your current rom with apps etc .
i use GingerXperia(with all xperia apps) V22 on stock kernel. its very nice.
i something gets wrong you mostly can restore your phone with sony ericsson update service.

wifi/data problem

So suddenly my phones wifi and mobile data has stopped. I can't recover from a older back-up as i don't have one (tottaly forgot to make one) now when i try to repair it with PCC it says that the sofware has been modified and can't help ect.
I'm from belgium and i am now on fw 9.1.A1.140 but I can't seem to find the exect fw back in the thread. Can I also flash a other fw? My phone has root, unlocked bootloader doom kernel 7. Pleas some advise what should I do?
Try flashing doomkernel again in recovery.
Or try flashing a stock FTF in flashtool or a stock based custom rom.
Do a full factory reset before doing so and make sure you backup anything you want to keep
After leaving ma phone home for a day from school, things are back to normal.. Very strange.. Now going to see if the problem occurs again, but in the weekend I'm going to reset my phone, just to be sure. Btw, had already flashed the doomkernel again and it didn't work. Ether way, I'm happy now that for some reason everything is working again.

Steps for Switching Rom
I am currently using Cm11 on sony xperia sp, I have a unlocked BL and root access.
I would like to switch to a new custom rom now like XperianZe. I tried also, and in the process i bricked and also had a bootloop.
Can anyone please explain the detailed steps to do a fresh install to a new custom rom like XperianZe.

Just follow the mentioned instructions in the respective thread. And as for Xperianz as you mentioned, you have to read this post.
Based on the post, it seemed the installation is straight forward. What makes you have a bootloop? Did you flashed the kernel mentioned in the thread via fastboot?

yes, you guessed correct. i tried flashing the kernel. And the phone didn't start at all.. not even power up.
Later i read a post in XDA, in which it was described that i should do a hard rest by pushing the hole button at back and then try to boot.
Tats when i got boot-loop. I again flashed the custom kernel (DooMLoRD) and did installed CM11 again using CM recovery. Then the phone booted cm 11.
I followed this link and tried doing so. which resulted in phone not powering up and then boot-loop.
So now if i install Xperianz ROM following instruction in this link, it should be working properly correct?
Am sorry if am asking dump questions. Now am a bit scared to try to switch to this cutom ROM as i may end up bricking the phone again. The thing is I really don't want to mess it up again.
I am new to rooting n playing around with custom ROM. CM11 was my first try and was a success in first go.
Thank you for helping me.

I am concerned about how you flashed the kernel. How did you flash the kernel provided in the thread? Did you use adb or FlashTool?
If you want to try any other you can use Existenz as it require only the stock kernel.

I used FLashtool to flash the kernal.
If my understanding is correct, As of now i am not on stock kernal. When instaling CM11, I flashed the kernal of DoomLord for getting CM 6. recovery.
If this is the case should i flash the stock kernal first and then give a try for Existenz?

Well Existenze require most Sony things out of the box, so you'll first need to have Stock ROM in place before flashing it's ZIP. I've dug through the Xperianze thread for you and seemed like your problem is not to be found in the thread. If you really want to try out Xperianze, you might want to flash the kernel via fastboot using adb, rather than Flashtool.

I bricked my Xperia Z - Please help

I was using PAC ROM on my Xperia Z since after few weeks after buying the phone, but i find PAC rom kinda slow, so I wanted to go back to stock kernel,rom. So I decidede to relock bootloader(I already did it once and went back to PAC). But this time, after relock my phone is dead, all I can do is get it into flashmode and fastboot. I am not able to flash stock firmware. I need help, please guys. I can post logs, screenshot, whatever you need.
if the phone is able to get into flashmode and fastboot it is not bricked at all you should be able to reflash stock rom without any issue I suggest using flashtool and google how to flash to stock rom xperia z
Thank you for your fast reply. I am gonna keep trying from other PCs, with fresh install of flashtool and drivers. Does the version of stock firmware make any difference?
I have managed to unbrick it by flashing stock firmware as you said. I am very happy but I would still like to get my device rooted, But something based on stock kernel not some crazy stuff. Could you tell me how? Dont wanna mess up things again
