[Q] Restore Xperia Arc To Stock Rom (Ics) From Cm9 - Xperia Arc Q&A, Help & Troubleshooting

Hi ,
I need some help in resolving issues with my Sony Ericsson Xperia Arc S (LT18i). sorry for big post.
I searched over this and CM forums for similar issues/detailed stapes, but failed. please forgive if its same dumb question asked by several people, but right direction will be helpful.
I have loaded Cynogenmod on my mobile, but now I want to goto stok firmware. Please guide me the steps for noob. Small back ground:
My bro bought this phone a year back and felt its slow and struck some times. So, I collected it from him and want to resolve issues . observed that there is a lag while opening dailer sometimes and sometimes after dailing number it takes approx 5-7 minutes to start dailing. so, wanted to resolve it .
What I did: I read a guide for rooting talk dot sonymobile website and rooted using Eroot_V1.3.4. (also unlocked bootloader using sony official code from website developer.sonymobile as suggested at cyanogenmod wiki Install_CM_for_anzu)
Finally I got Cynogenmod on my mobile. but I observed many bugs in it. the Slow/lagging problem still exists.
Yesterday when I tried to switch on bluetooth, the mobile went crazy. it automatically rebooting for every 3-5 minutes.
I went to recovery mode, tried different options, no use.
Actually I have taken backup before installing cynogenmod (cm-9.1.0-anzu.zip).
I took backup in view of going back, if some thing goes wrong. I thought it is the offical stock ware backup(rooted,unlocked and CWM added stock).So, just want to go back and tried to restore it. After sometime CWM restore completed when i rebooted system is up without any message on screen , I can see mobile is on by light.no flash screen nothing. after 10 minutes, I had to got back to latest backup of Cynogenmod.
Now I can see mobile is starting and CWm loaded but started rebooting loop. Then as a last try I have wiped cache/data.
Now my mobile is working but sometimes getting rebooted.
So, in this situation I want to go back to stock rom.
Please advise me how to go back. I dont need unrooting or unlocking boot loader. Just going back to stock is fine.
the dailer lag, dailing lag are ok for now. Please help.
Thanks,
Aditya

Dear SGY,
Thanks for quick answer.I checked the link suggested.I have downloaded the firmware link provided in that link. But I am confused whether it suits my situation or not.
I am worrying that if something go wrong my mobile might brick.
the reason for worry is as I already had cynogenmod. is that ok ?
one more question is that in CWM i have taken backup before installing cynogen mod. Is it not stock firmware ? If no, is that data backup ?
If it is data backup, can I restore that backup after following steps to get back stock firmware.
Sorry for too many questions.

thank you. now i could revert back my firmware. need to check how works

have played to change simcard...usualy I always shut the phone before, but for a reason, I changed my sim without shutting down the phone.. .from there the phone have rebooted by itself but stayed on the at&t logo!! it provoked probably a kind of glitch.. have waited at least half an hours but stayed at the at&t logo....so I knew that I was in problem from there.....lolllllll
soooo I had to reflash....and set-up from zero.....naturally I didn't be able to just flash the kernel...wich I'm positive will have revive the phone......but lg tool only make a complet new flashing....
end of story......shut your phone before changing your sim....

Help me Please, I'm the worse and the most stupid Noob ever!!!

Help me help me please, I'm so stupid , I have an AT&T S3 unlocked and I'm currently using Tmobile...
I rooted my phone, and I used DEBLOATER FREE, to debloat some of the stuffs in the list. I was actually being careful with the selection. Anyway, I deleted some files, and when I restarted the phone. I'm no longer getting signal. Can someone please help me. I need to get it fix soon. Any helps and advices at this point would be greatly appreciated. Please by the way, i tried to go to setting ->More setting->Mobile Networks, and it freezzed and received a message "unfortunately, settings has stopped"
I used mskip's tool to rooted my phone, if i used that tool to relfash my stock recovery, would this solve the issue?
or I'm on ICS 4.0.4 right now, If i Update the phone to JB would this solve the issue.
Let me add one more thing that, I rooted this phone a long time ago, today i was being stupid and debloat stuffs assuming it won't affect my phone much

just reflash stock rom via odin using this tutorial here ----> you will lose all data so find a way to back it up to your computer.

First of, thanks you so much. I don't think you attach a link for me yet. A quick update, I checked my imei, and it said null/null. so if i used mskip tool to do a efs partition would that solve the issue?
I'm downloading the ics stock rom right now, and I will keep you update. I will probably do it, via mskip's tool. What I'm wondering is, if i used samsung kies and update to JB, would this solve the issue also?
the phone is working fine, it's just i can't make call

I did more research and I think I narrow it down to EFS, mb i deleted my efs folder while debloated my phone, or some random reason...do you know any possible fix? because I didn't back it up. if I'm to re flash stock rom, do you think it will fix this issue?
I found this guide right here: http://forum.xda-developers.com/showthread.php?t=1264021
so i re-flashed the stock rom using mskip tool, and now i can make call, but now i'm getting a bunch of messages like process android.process.acore has stopped, and touchwiz home error and i can't get pass that. Please Advise
[SOLVED] thank you so much, got everything back to normal. one more questions, since i re-flashed the stock rom, I can still access CWM recovery, but as i tried to install superuser, it said I can't...this is my first time so can you lead me to the right path?
Just re root your device using the same method.

[Q] Slightly messed up my firmware

Hello there,
I'm very new, so apologies if I'm posting in the wrong forum, or if there's a more appropriate place for this quesion!
Here's the thing... In an attempt to root my Sony Xperia C1905, I was trying to revert my firmware to a previous version of Android (4.2, I think). Anyway, something happened and things didn't work out, so I re-flashed it with a version of 4.3 that I downloaded from somewhere (I don't know where, but the default language was set to German!)... Thing is, when I turn my phone on, I get stuck in a boot-loop (pretty Xperia colous) for about 3-5 minutes until it gets to the main screen.
I have tried things like using the Sony PC Companion to repair it, but to no avail. Is there some other way I can fix this, or revert it to its original firmware, without this stupid boot-loop?
Thanks for reading!

Please refer to this thread as it will tell you how to flash .ftf files manually. Also, make sure that you tick wipe data and wipe cache. This is probably the source of your bootloop problems. Have a good day, feel free to PM me if you need more help.
Wait, buddy i might be wrong here but did you say that it goes to the min screen after the bootanimation ( pretty colours). If so, then that isnt a bootloop. A bootloop is when your phone stays on that bootanimation and never loads up, it's also called a soft brick. As gamer649 above me said, you might wanna check out that thread to know how to flash ftfs manually.
Thank you both so much for responding so quickly! I shall indeed check out that thread posted by gamer649 and hope that solves the problem (If not I shall report back.)
Thanks again!

Ah yeah, you're right, it's not a boot-loop in that case because it does indeed load up after a while, my mistake!

Oppo find 7 X9076 rom problem, radi and wifi +

Hello, i hope there is someone that can help me with this problem i have.
I rooted and used cm12 sometime in the begining og 2015, then i unified the phone and used another rom(dont remember what), but it crashed sometime last summer and went black.
And after i have had it i started reading and found some posts and figured out i could try to get life in it befor cristhmas, and i found this: community.oppo.com/en/forum.php?mod=viewthread&tid=23067&extra=&page=1[/url]
And i found a computer with win 7 on, and i got the phone back to life, but the rom stopped at language or region settings at installing.
and the i tried using nameless-recovery-twrp-2.8.7.0-find7-20151220 and the rom will start up, but i dont have wifi, radio or IMEI.
And i found someone that gave me oneplus.qcn this file, but i cant get my phone in to diagnostic mode, becouse the code *#801# is not working on my phone(Only *#06# is working).
I have tried different roms and recovery, but onlu namless rom is working in that way that i can start a rom (color os 1.4i up to 1,8i) over 1.8 will not start.
So i would be wery happy if there is someone that can help me fix it..
And i apologies for my English, but hopfully it is possible to understand.
Kindly regard
Johan

Have you tried reverting back to stock ColorOS rom? Try to flash stock ColorOS 2.0.8i or ColorOS 2.1.5i to your phone. Usually when things go bad, people usually revert back to stock coloros rom and that fixed their problems as it fixed mine before this.

The phone will only start up when i use colosos 1.4 up to 1.8, when i use higher or lower it will not start up..
And i can not use color recovery, only with nameless-recovery-twrp-2.8.7.0-find7-20151220..
