[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..

Miui

Do i have to have stock .587 to flash in the latest miui update from this post http://forum.xda-developers.com/showthread.php?t=1851262
And also, when i install the rom, do i just run Aroma installer instead of wiping cache and dalvik then flashing the rom in?
Thanks

Did you flashed the MIUI kernel?

no
where can i find that?

Is the "boot.img" inside the MIUI.zip
(only if you have unlocked bootloader)
or you can go back to stock rom using sony update service

There are no boot.img inside the MIUI.zip,

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.

I think you should flash kernels via fastboot.

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.

AW: Need Help
Always give the recovery log...
& exact error code ^^
Than search google.
Than xda.
Than post ^^

flash newest sony ics stock rom-->fastboot kernel in the cm zip-->wipe all cm need-->use cwm flash rom-->use cwm flash gapp (goo.im/gapps) (ex: cm10 should be gapps-jb-20121011-signed.zip)-->enjoy!!

So you didn't see the boot animation after kernel screen?
How do you flash the kernel? Did you see it finished successful on screen?

[Q] LT26 stuck at Sony logo after failed flashing

Hello, at start I apologize for my poor english, but I hope, that you'll understand what's the matter.
First I prepared to install new rom on my Xperia - I've rooted phone and installed CWM. After that I've launched CWM, then I've erased whole phone's memory - cache, system, data and dalvik. When I want to install rom from .zip file i get info, that file is bad. Next I've tried to launch mass storage mode to copy rom one more time and CWM was unable to open ums lunfile. When I've rebooted phone only thing I saw was Sony logo. Now I'm stucked at it. Phone have locked bootloader, so I can't launch fastboot mode. Adb can't find any connected devices. What can I do now?

Use flashtool and flash a stock ftf.
You must have unlocked your bootloader and hence seus gives that error.

Okay, so here is what you must do :-
1. Download stock ics ftf from here - http://ni.0a0.in/files/3432_kznsa/LT26i_6.1.A.2.55_SG Generic (1257-6921).zip
2. Extract the zip to get the ftf file.
3. Flash it with flashtool
4. Flash this custom kernel - http://forum.xda-developers.com/showthread.php?t=1729280
5. Then go and check out any custom roms that you like
All (most) custom kernels have CWM in them. As you have unlocked your bootloader, you can flash a custom kernel and get CWM. Also, each time you wipe /system nothing will happen to CWM. CWM remains intact
Good luck!

thanks

[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

Flash a kernel that has CWM using fastboot.

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?
