[ Q ] after sotware upgrade - phone dead

Hello,
3 day's ago I bought Se arc and first thing what I want to do was find the latest version of firmware for this phone. I connect to my wifi, downloaded the latest soft version 4.0 and clicked install. After installing the phone has shutdown and does not respond now. After pressing the power button flash only for a moment the green light and thats all. After reading forum I tried to flash it and install 3.0.1.A.0.145 FT but still no reaction what can i do next ?
maybe you have an unlocked bootloader?!
Maybe your bootloader was unlocked and the OTA update brick your phone.
Just look in: Fix FOTA bricked phones
If that's the problem, you will find some usefull information to repair.
Bukest
yessssssssss it works
thanks
strange thing that you bought a bootloader unlocked phone, you can get problems with your warranty

thats why was so cheap ;/
ok, my phone work now and I wont to get new software version 4.0 what can I do ?
When I take update software in telephone always after instalation it doesn't wont turn on, but after connecting to pc companion 2.0 also I have error "Your phone contains a modified software, which can not be updated"
You have two options:
1.As you are already unlocked simply flash a custom ROM (Check for DoomLord's kernel in the forum).. U get root, ability to overclock and tons of other stuff..
2. If you want to stick to stock SE.. Relock bootloader and then update.. (Check the namaste guide..)
I'd go with the first one
I have new soft in my ARC
i do this i my way - I search forum xda for new soft for arc 4.0 and using flashtool instaled that soft and working ;] symply and quickly

[Q] Updating Play After Unlocking Bootloader

Hi
I have just unlocked the boot loader on my SEXplay and was wondering about updating the phone to a newer firmware then putting doomkernel on.
Basically to cut a long story short, Can I do it through the PC companion or do I have to flash a newer version onto it?
Also if I have to flash could one of you fine members provide me with a link to the new one.
Thanks All
I think you'll have to flash. Btw, SEXplay sounds.. Well.. Wrong.

[Q] Help needed regarding .587 and downgrading !!!

Hey,
I am new to this forum and have been getting great help from this forum over all. The issue is that I have been using SE Xperia ARC LT15i for almost over an year now. I was on FW 4.0.a.2.368 (2.3.3) earlier and was going pretty good with it until i decided to upgrade my ARC to ICS 4.1.B.0.587 (4.0.4) through FlashTool and rooted it with DoomLord's method.
Now the problem i am facing right now... i am not quite satisfied with it. Problems and issues are same as many of us are having. Camera performance not that good, SMS LED not working, over all the phone is quite laggy. Can't play games... touch respond not that good as compared to previous FW. I like to use camera alot but cemera performance not good specially the video player. I like to play games in my free time but games are so laggy that it's almost impossible to play. Now what should i do about it? I want suggestions.
1. Should i downgrade to 2.3.4 (4.0.2.A.0.62)?
If i downgrade... my phone would still be rooted? Bacause i heard that FW 4.0.2.A.0.62 can't be rooted. Plus how to downgrade... Through FLASHTOOL or through CWM?
2. Is there any other FW or ROM available that can still increase my phone's performance? I saw many ROMs like AOKP / CM10 / Ultimate HD but i have a locked bootloader so can't use them plus i don't know how to use CWM? I tried ROM manager, X-parts but some how I can't boot into CWM. Every time i restart my phone (press volume down key at SONY logo)... it boots in Safe Mode . I love to try new things out but some how... this CWM thingy isn't helping me out. Over all i like ICS because it has given new feeling to my phone my this laggy thing is getting on my nerves :crying:
Here\s my phone info:
Model Number: LT15i
Android Version: 4.0.4
Baseband Ver: 8x55A-AAABQOAZM-203028G-77
Kernel Ver: 2.6.32.9-perf
[email protected]#1
Build Number: 4.1.B.0.587
So which option should i go for... should i downgrade and how would i downgrade to 2.3.4 or should i go for a new ROM (Locked Bootloader plus CWM not working) help needed badly from GURUs !!!
P.S: Don't ask me to search it out... because some how i couldn't find any topic like this before. That's why i am threading it.

Is your boootloader locked - or unlocked?
If it is unlocked then u have no problem with rooting...
If it is locked then u can flash a .42 GB firmware via flashtools and downgrade then root it.. Then you can OTA update ur firmware and still have root..

[Q] downgrade from 4.4.2 to official 4.3 can i use Odin?

Hi guys,
i'll sell my 7105 in few days so i'd like to set back official rom!
my only doubt is right now i'm using custom rom on 4.4.2 can i just wipe all go in DOWNLOAD mode and install 4.3 official rom?
about keeping the root ?
thanks
Yes, Odin is the way to go. You don't necessarily have to wipe anything, but I would do so to make sure it is factory reset and to prevent you from boot loop.
Flashing stock will unroot the phone, but it won't reset the flash counter! Consider to do that as well as you are going to sell it.
thanks Yakobus for your reply.. actually i did act before reading ur msg
well i was just scared to destroy note 2 just few days before leaving me ahah!
FYI , for those like me willing to know, this is what i did...
I've got latest rom from sammobile..
I used trianlge away and then i went in recovery over my phone!
once in recovery i wiped ALL.. and i mean all with TWRP recovery!
from there i rebooted phone in DOWNLOAD mode and i used ODIN pc (u can find step by step by Dr Ketan or other post)
flashed 4.3 to my phone, when rebooted everything was working ( yes also wifi )
COUNTER went back to ZERO ... Knox is installed (apparently) but honestly i couldn't care less..
everything good if anyone has some doubts.. ask
:highfive:
You are welcome. Good to see everything went fine and thank you for the summary!
Edit:
What I did not have in mind: Your Knox counter is probably set to 0x1 as you were using a custom ROM. You cannot reset it so far and I do not know what that means for our warranty as it depends on your country's laws and your provider/seller.
with some more details pls , i'm a noob , had note II 4.3 JB , upgraded to 4.4.2 official kit kat and want to downgrade , i didn't root it , i didn't do anything at all and i dont want to lose the phone i just bought a week ago , can u help me?

Need Serious Help

Dear All,
I have purchased LG F180 handset today in used condition. The previous user had VDT Rom-Choi Installed in it with android jelly bean 4.1.2 version and phone is having root access that I checked from root checker. Now I want to install Sling ROM version 2.2.2 but below are some issue which I came across while playing with my phone.
1. When I downloaded freegee from play store it is saying my device is not supported. Whereas when I checked from imei.info page below are the results;
Model: Swift G F180
Brand: LG
However the seller confirms me that It is F180L model
2. I am unable to get in Fastboot/revovery mode, I tried volume up+power button but nothing happen LG logo blink twice and device powered off. Then I restarted my device and back to the home screen.
As per the guides available Here we can unlock boot loader and install CWM by freegee.. as mentioned below;
6.Q: How do I unlock the bootloader?
A: It’s easy, using FREEGEE app from playstore. Both free and donate apps work.But I suggest using the paid app, to thanks Shelnutt2 for his wonderful work. He deserves a beer.
The reason of buying this handset is this ROM... I have purchased this handset with so much hope.. But when I came across to the above mentioned things.. I am a bit worried.. Please help me resolve this.. so I can able to get the ROM which I liked most.
First of all your bootloader is already unlocked you can't flash a custom rom with locked bootloader so if you have vdt you are unlocked the best thing to do is download cwm manager from playstore and flash cwm if nothing happens you should consider flashing kds for installing the original software back again and start from scratch root phone using framaroot and unlock bootloader using freegee then you‘ll have the latest mako bootloader unlocked and the latest custom recovery cwm or twrp and you could flash anything you want.
Thank you soo much.. I have done it

OTA update ur is to latest... Don't forget to Factory reset after each update. Stock KitKat update will make ur app data partition to 2GB. Then u can Sling 2.2.2 or MC Dev V7
