[Q] Going from Cyanogenmod, back to stock - Xperia Arc Q&A, Help & Troubleshooting

Hello.
I installed Cyanogenmod 7.1 on my Xperia Arc when it was released a while ago. I'm having so much trouble with it, and I miss some of the essential features SE had implemented into the stock firmware which has made me want to go back.
How do I do this the "correct" way, so I can go back to stock, recieve official updates etc?
When I connect my phone to PC Companion it tells me there is an update available. I assume this is because CM 7.1 is based on a slightly older firmware for the Arc, so what will happen if I press accept? Will it just install the newest stock firmware or do I risk bricking it?
I did create a backup of current installation in ClockworkMod before installing Cyanogenmod.

Okay. I used this guide to use flashtool
http://forum.xda-developers.com/showthread.php?p=10879507#post10879507
I came to the point where it said "flashing finished" and "unplug the device and power it on" but nothing is happening when I press the power button.
So I guess thats it then..

Here is the Flashtool log.
there is no reaction from my phone now
EDIT: Ok, I'm too new to post a link obviously
EDIT 2: I tried using WotanClient to flash it again, and the flashing process went fine, but it still won't turn on. I've taken the battery in and out several times. When I hold the power button down, the LED light just flashes green but nothing happens.
EDIT 3: Ok I fixed it with this: http://forum.xda-developers.com/showthread.php?t=1126358 it worked for some reason, although that was not the problem. I never updated it. But at least it works now, so hopefully I can lock the bootloader and finally fix this.

Can you feel 3/5/7 vibrates when holding power button?
What did you try to do actually?
It's a phone sync software and not a ROM update which you have mentioned.
It seems that there might be problem with your battery. Check it first.

Did you root phone earlier? or
Is your phone's Bootloader unlocked?
If your bootloader is unlocked and your device rooted, install CWM Recovery via ADB, then download your ROM as a ZIP and install using CWM.
If you're not unlocked/rooted, do that first, again via ADB.

i guess the phone it is now useless because another guys says that
"Its bricked if you cant boot to hboot with vol-d + pwr. Srry only way is to send to htc"
so i guess that's the end of it
today i pressed both vol + and down and pressed power button.. the phone gave 7 vibrations and its LED turned on.
what does that mean? is there way to fix it somehow?

I think I killed my Arc. Is there anything I can do?

What is is:
Docomo Xperia Arc LT15i, flashed ICS LT18i firmware a while ago, which has worked fine.
I currently use a GNex as my primary phone, and decided to convert my Xperia Arc into a portable music player, just running ubermusic with a microSD card.
What happened:
Yesterday when I connected it to wifi there was a system update notification. I thought, sure, let's see what it does. Perhaps that was stupid, not sure. It downloaded the update, rebooted and started to update. Got about a quarter of the way and then went blank. That was the last I saw anything on the screen.
What is does now:
I tried to power it on but nothing happened. It won't even boot. When I hold the power button down, the led light blinks green (about one blink per second, very brief blinks). I plugged it into USB, and flashtools recognized it in flash mode (without holding down the back button when plugging it in...). I then tried to flash the newest generic global (4.1.B.0.431), which flashtools showed as completed and successfully flashed. But it also said "please wait a moment, the phone will reboot", which it never did. Flashtools showed it as still connected in flash mode. I unplugged it and tried again, same as before. Won't even boot. I tried a couple more times flashing the same and previous firmwares (4.0.2.A.0.42), but still nothing.
It seems totally bricked, and I think I killed it. All I can get is flashmode.
Any suggestions or ideas? Or am I just stupid for trying to see what the update would do? I figured there's always some way to fix the system, since the hardware is fine.
I invited myself to the same problem but in a different way, result is same bro
please help us folks
Did you unlock the bootloader?
Is ur Bootloader Locked or Unlocked ??
I think you could be suffering from the 0% battery Issue (just a guess).
Try reflashing LT15 firmware with Flashtools & when it says flashing finished device rebooting ,then unplug the device & turn it on.

Bootloader is unlocked. So yes, trying to accept the OTA system update with an unlocked bootloader was stupid.
I've tried flashing several times, and of course I try turning it on at that point, but nothing. I'll look into the 0% battery issue, haven't read about that.
Here is the thread, sorry I didn't find it in my previous searches. This solution worked for me. We can close this thread.
You can attempt using s1tool and test point to relock the BL then use sues to fix.

Xperia Play R800at stuck in boot loop (never rooted)

Hi,
This is my brother's phone, and he tells me he went to use it the other day and the phone was off. When he turned it on it would show the "Sony Ericsson" screen, then the AT&T logo and back to the Sony screen, and the loop continues. The only way to make it stop is to remove the battery.
His phone is stock and has never been rooted or unlocked. I tried flashtools but can't use it because the phone has a locked boot loader. I tried to unlock it through the Sony mobile site, but can't because it asks to go to the menu of the phone which I cannot do for obvious reasons to verify if it is unlockable. I tried to do so anyway, but the instructions say that you press the "search" key while connecting it to the computer and a BLUE LED would turn on, this phone turns on Orange. At this point I am stuck and don't have a clue what can be done now.
What I really want is to just get the phone working, it doesn't matter if it goes back to stock or if it will have a custom firmware, just to get it working again.
I appreciate if someone points me to the right direction on what I can do to restore the phone. Any tutorials or instructions related to this specific issue. I have found multiple threads similar to this but all involved previously rooted/unlocked phones. Also, I mostly use Linux so any instructions for Linux users would be great.
Thanks
You don't. Need to unlock it top use flash tool. Download an ftf for the phone. And choose flash mode in flash tool. Then choose the ftf you want to flash. And it will tell you to unplug the phone and plug it back in while holding the back button. A green led should turn on then it should flash the data and reboot and it will be back to stock

As above, Flashtool doesn't require an unlocked bootloader. A link to the stock R800at firmwire here: http://forum.xda-developers.com/showthread.php?t=1589399
Thanks! This worked perfectly, I mistakenly downloaded what Sony calls "Flashtool" on the Sony mobile site (named "Emma" when installed).
Any idea what could have happened to the phone in the first place to render it unbootable?
Again thanks for your help!
Could be the cache/dalvik partitions messing up. Usually when I get the same problem I just pop into recovery and clear these, but that does require root.
Quite strange for it to happen on a stock, non-rooted device though. Is the device working now?

You don't need root to have recovery, unlocked bootloader is enough. Just saying

[Q] Clockworkmod froze during restore phone is brick-ish right now.

I spend the afternoon dicking around with my phone, because this was a plan I made a backup with clockwork mod.
I did something that caused a boot loop, no problem, restore from backup took a while but it went. then I tried again, but a little differently. same result. (after two failures I was just going to give up) got into recovery again and went to restore again. set the phone down, went and watched tv for half an hour. come back it's still on the screen for the restore. I look and the status bar is frozen, it doesn't look like it's done anything. Not much I can do at this point but reset it. I hit the reset button behind the panel and expected to be able to try again. WRONG. phone turns on, boots to the SONY logo screen and stays there. so I decided well I've rooted it once I can do it again. go to flash re-flash it, but when I boot into flash mode it says it's flashing data, but isn't actually doing anything. the status bar doesn't move nothing seems to be doing anything. Is there anything you can suggest to me that might get my phone up and running? I'm stuck using my old ARC which had it's problems, hence the upgrade.

Flash ftf file using flashtool or try repair feature in PC companion. Or maybe u can flash latest mod kernel and try to restore ur backup.
Before u begin flashing, please backup ur TA, u can find the guide in Z forum. Just for ur backup but please read carefully the procedure becoz messing with TA is extremely dangerous.

I've been trying to flash a new ftf, but it get stuck at "Flashing Data" and the bar sits at 0%
I can't backup anything any more and I can't flash the kernel because my phone doesn't have an unlockable bootloader, so I can't enable fastboot.

[Q] Custom Kernel Flashing ends with black screen , Arc S

Hi everyone,
I really like my arc s and I don't want to change it if it does not fail. However, I decided try new ROMS just to make my device a bit different with improved performance.
I checked several of threads and read them carefully. I have already finished these steps (I hope I managed to do properly) :good:
=unlocked boot loader
=rooted with a software called eroot
=installed ClockWorkMod Recovery 5.0.2.7-nAa-r2
As much I understand everything is ready.
So I have downloaded a 4.2 JB custom ROM. I put the zip files to my SD card and also extracted boot.img file to my desktop. By using Flashtool, I flashed it. After that, I rebooted the device to enter CWM mod to be able to load the ROM and googleapps. However, I only get BLACK screen everytime. (I press volume down and power button) .
I followed 3-4 different techniques and different kernels and roms but everytime the result is black unresponsive secreen, I only get small vibration and than black screen forever. Thankfully, I manage to save the device but loading LT18i_4.1.B.0.587_(1254-2184).ftf with flashtool flash mode. However, I really want a shiny 4.2 in my mobile .
By the way, about my phone : android 4.0.4 kernel 2.6.32.9-perf
I don't know what I am doing wrong with flashing kernel...
Please share your experiences...
Regards
Onur
Hi again,
Seriously guys, I really need advanced help here. I spent 2 days for it, result is nothing.

What is the kernel logo that pops up, are you sure the kernel flashed correctly
Sent from my Nexus 5 using xda app-developers app
At least I have identified the problem, I guess
At first I didn't consider that as a problem but I think the reason of this kernel flashing problem is an issue about internal memory of the device. While flashing the kernel with flashtool, an error occurs "1 bad blocks encountered" (check the attachment pls), I did a quick search on the forum as well as Mr Google however the outcome is a bit devastating unfortunately. I think it is impossible to solve the problem. Still, I will be really appreciated if someone shares his/her solution for this problem.
Otherwise, I m kindly asking for ROM suggestions to upgrde my arc s (4.0.4 with kernel 2.6.32.9) without flashing a custom kernel.
Many thanks...
