[Q] Xperia arc - stuck in Boot Loop issue - Please Help

Hey Guyz,
i unlocked by bootloader using fast boot method
then i rooted my phone using the same method and it was working fine.
Yesterday i installed CW rom and CWM autoinstaller , to reboot in recovery and installed a mod to bring reboot in Power Off menu options.. it intalled correctly.
But when i rebooted the phone, the sony ericcson logo appears again and again.. i.e it is stuck in boot loop.. m still able to enter in recovery but unable to boot my phone properly..
Please Help...

The First solution is to flash a stock firmware using flashtool.
But which Kernel and which Rom have you tried to flash?

k.. i'l try to flash 4.0.a.283 using fastboot..
BTW
I am noob.. Dont know anything about anything about kernel.. all i did was install Clock work rom.. When i opened it, it said, "you need to install CWM". So i installled CWM autoinstaller...
Now with everything installed, i booted into recovery and installed a mod ( which brings the option to reboot in Power Off menu). It installed correctly... Then i clicked on reboot system now.. That is when i realized that m stuck in boot loop..

You must first check the compatibilty of "reboot mod" with the firmware version you use.
Just check the firmware you have in your phone and make sure it matches with the firmware on which the mod is based.

@wayne
I have flashed my phone using fastboot method just like i did it when i was rooting my phone. And Thank GOD it is working fine now..
@KingWecked,
M still trying to figure out, where did i go wrong at the first place...
was it the CWM auto installer ??
or was it the Reboot mod ?? coz i downloaded the mod for xperia arc only..
Do we need to change that kernel thing after rooting ??
I don't know what the hell is a kernel; and after rooting i haven't done anything with my kernel. Should i ???

A kernel is the base of what Android runs

Before you install any mod,you must first check the firmware version you are using.You can find it out from Settings-->About Phone-->Build Number.
It contains the firmware version on which your phone is running Ex:4.0.a.283
.283 is the old version firmware and most of the mods dont work on this firmware.You must flash the latest firmware .42 in order to support the majority of the mods and themes available in this forum
And a kernel is very complicated thing.you must not mess with it unless you know what you are doing.Manipulating your kernel might brick your phone permanently.And if you want to know much further about kernels then search the forum and you must find loads of threads explaining about kernels and stuff related with it

@ KingWickedd
are u sure .283 is an old firmware
Coz initially i had "unrooted .62"
For rooting purpose i downloaded this firmware..
So can U please tell me where can i get " rooted 0.42 firmware" where i can start installing all mods right away..
Note: Multiupload links are not working ... Any other links ????

Yes I am sure its the old version where as .42/.62/.69 are the latest firmware versions.They have almost everything in common and they differ based on the regions they are released in.
For rooted .42 firmware..follow this link below..

CWM is gone after Xperia IC pureness

Hi,
I install a new rom ( the xperia ice cream pureness ) and after I install it, the CWM is gone, I cannot access the way I did before... I think is because i wipe everything when I install this rom... but now I have my doubts about this, because when I install the CWM I was on GB... I dont want to use the same method that I use before because I dont know if is compatible with ICS... and I read about new ways to install CWM on ICS but all of them request the stock rom.... is there is a way to install or run CWM on ICS pureness rom ????

Hi there,
One thing you can try is to use a kernel that has CWM built into it.
The one I know that's stable and good battery life is called "ArcKnight v3.3 stock" - This is good if you don't want to mess around with overclocking and stuff like that.
Then when you boot, you press the "volume down" button when the led lights up for the 1st time.
So the CWM recovery is built into the kernel.
I think there is also a well supported kernel called "doom kernel". I have not tried it, but many suggest it in their posts.
hope things go well.

You are on locked bootloader right?
If answer is yes, CWM is installed on the ROM. That means that after flashing a new ROM, it was wiped.
If you are on unlocked bootlader, install a Kernel that has CWM installed in it and you will never lose it.

Best thing to do is to reinstall

Warning is there so i don't have to deal with the bugs that arise from ppl with broken roms most of the time it will all be fine.
Try tapping the screen / volume buttons / power button (tapping) ect.

When the Sony Ericsson logo lited up, tap on the logo. I did that nowadays, when there's no blue led after installed cwm5.

Guys i need some advice with rooting my friend's Arc s. Here s what i did
Phone was on official ICS. I unlocked the bootloader using the official method.
Then i rooted it using some one click root method
Then installed recovery using recoverx software
Booted to recovery, wipe data, format system
Then tried to install a rom called racing bean. But i got and status 7 error. I tried some other JB rom.
But got the same error
Then i switched off and tried get to recovey. but could not
So i relocked the bootloader and installed official ICS again to boot the phone. The phone is fine now.
so can anybody help me to properly do this?? I just want to install CM on this phone

Racing bean or any other jb rom needs a JB Kernel too!.the ics kernel and jb rom mismatch might give that error.First flash a jb kernel and then it should work fine. This one's what i use http://forum.xda-developers.com/showthread.php?t=1885559.

First, you forgot kernel. Second make a backup with cwm before any wipe.

I flashed lupus kernel but after that i could not get into recovey. How can i do that?? I had the same problem with Arc fusion kernel

Well,there shouldnt be any problem,vol down or up button while the device lights up(led glows) does the job.But maybe u can try flashing it agn..if still having an issue..use an app like rom toolbox or boot manager to reboot into recovery..btw srry for the late reply

I gave up the effort. I tried about 6 Roms and kernels. Even ICS kernels with ICS roms. But After flashing the rom the phone does not go pass the kernel boot screen. I had to relock the bootloader and flash the stock Rom again. I have flashed hundreds of roms on so many devices. But never faced this kind of situation

Not sure why you would have installed RecoverX if you have an unlocked bootloader as all you need to do is flash a kernel that includes CWM.

Ya right i did flash the kernel via fastboot. Then booted into CWM and flashed the rom. But when i reboot it gets stuck at kernel screen

This happened to me and all I did was leave the phone like 10 mins booting, then it magically worked. I'm using Arc fusion 4.3 with racing bean, no problems. Try this, flash lupus kernel, wipe everything, go on fastboot and flash fusion, try to go on cwm and if it works, try to install racingbean again. At least that's one of the things I did.

Stuck at CM9.1 animation after flashing Xperia S

Hi !
I have a locked A.55 Xperia S from Dubai and were trying to install CM9.1 (stable) but now, its stuck at the Cyanogenmod animation. I waited for like 10 minutes but it just won't go from there. Re-flashing the kernal and wiping and then re-installing CM9.1 didn't work.
What I did:
1. Installed the drivers from Google dev website with fastmode driver from Sony dev site.
Selected the ADB mode driver (not the bootloader driver) for the S1boot device in Device Manager.
2. Rooted using Easy Root 1.2 (chinese version)
(success, I could see superuser process in the apps)
3. Unlocked bootloader using the fastmode as mentioned in Sony's website.
4. Downloaded the CM9.1 nozomi from CM website and Gapps from another website and copied to the root of the internal memory (Xperia doesn't have memory card ?)
5. Installed CWM recovery (6.0.3 ?) using Recover X
6. Flashed CM kernal from the CM9.1 nozomi zip (boot.img) using flashtool 0.9.11
7. Backed up the existing data using CWM.
8. Flashed CM9.1 nozomi using CWM and then Gapps. Factory reset and Cache clear.
9. Stuck at FreeXperia logo
10. Gone to CWM and restored the backup but it gave an error with "can't format with mkextf4 /dev/block/mmcblk3322 (or something like that)
11. Stuck at XPERIA logo (animation)
12. Installed the CM9.1 and Gapps and then factory reset, cache reset and Dalvik cache clear (when I press on "clear Dalvik Cache", I don't see any message in the log btw)
13. Stuck at CM9.1 Robot animation (the matrix ?)
Please help guys...its my only phone and I'm a busy guy regarding phone calls and emails
Thanks for reading

Does flashing a different kernal a good idea ?

Where did you download your cm? FXP or CM official website? You can fix it by flashing stock firmware using flashtool.

Yeah, CM official website !
So, should I just download the stock firmware.zip and flash it with recovery or I have to download the .ftf file ?
I flashed the Pure ICS kernal but its stuck at the "Pure ICS kernal" logo.
What should I do now ?
Download the stock firmware ftf and flash it ?
From where I can get the kernal for the stock firmware?
Thanks bro for the reply !

Man ! I hate this
I have installed the drivers from the driver folder in the flashtool but when I connect my mobile in flashmode (green led), the add hardware wizard pops up and within 2 seconds, the phone boots up freezing the system.
The flashtool displays an error saying "install drivers".
I have installed all drivers using flashtool's driver installer but why does it still say its not installed ?

Didn't note the error down...gonna do it again to see what it says !
EDIT:
Can I use fastboot mode instead of flash mode in the flashtool ?

Now, it doesn't even recognize the phone....I mean, even if I connect it in flash mode (green led), the flashtool doesn't start the flashing
EDIT:
Is there any way I could access its memory ?
I'm thinking about downloading a stock ROM and kernal and flash it using CWM.

A miracle has happened!!
I could flash the firmware successfully., thanks JZ
Now I'm wondering whether I should go ahead and flash the cm9.1 again!!

[Q] Can't put CWM onto my Xperia Arc after using EMMA

Hi,
I have tried everything I've read so far and I still can't get the phone to boot into recovery.
I flashed the latest Stock ROM using Sony Ericsson 'Emma' flashtool.
Then I rooted using eroot and I have confirmed the root with the app Root Checker.
I installed ROM Manager but it says my device isn't recognised.
Also installed X-Parts and even though that said ClockWorkMod install was successful it still won't boot into recovery.
I have tried holding down various combination of keys whilst powering up but I don't even see a blue light appearing.
Is there any way to get CWM onto my Xperia Arc (LT15i) please?
Thanks for any advice

The kernel will depend on your ROM, so if you're using stock ROM you can flash a stock kernel with CWM on it. LuPuS stock kernel and Advanced stock kernel are two examples of stock kernel that have CWM.
Most custom ROM kernel should have CWM installed. Custom ROM will also come with its kernel so flash that and you should have CWM on your phone.

Hi popthosegaskets, thanks very much for helping me. I was wondering if you could tell me where I'm going wrong trying to install a CM Rom please. I've tried both CM 9 and CM 10 but the former caused the boot screen to flicker and flash and when I tried to install CM 10 I just got an error in CMW saying error in sdcard/cm10.zip (status 7).
The problem stems from me experimenting and putting on the Jellybeanv4 Rom. I found that the Settings button didn't function and overal performance was slow so that is why I'm trying to flash back to a Stable CM Rom.
These are the instructions I followed using flashtool.
1. Download rom, patch and gapps from Downloads and put in SD card
2. Flash Xperia Arc S 4.1.B.1.13 Vodafone DE firmware via flashtool (For increasing system and data memory for Arc user and latest BB) Must
3. Flash included FXP kernel or any CM10 based kernel using fastboot
4. Boot into CWM
5. Wipe factory reset (Data & Cache)
6. Go mounts and storage
7. Format /system
8. Flash rom then patch and at last gapps
9. Reboot
10. After booting 1 time you can flash addons if you want
Is it a problem with a conflict with the Vodafone DE Firmware and CM Rom?
Thanks again for your help and advice

I have same problem...
Same rom and same instalation guide...
Any solution to get in CWM?
