post an Odin screenshot if it doesn't go through

Hi guys!, first of all thank you for your support, here are the updates, i try flashing it via odin and a error was show and it was imposible to flash it that way, because i was desperate and impatient for having it back, i talk to a "expert" friend of mine, he told me that the problem was that the bootloader was locked by verizon, thats why i cant flash it, so he rooted the phone, and download e-z unlocker app or something like that, he install the app and then proceed to unlock the bootloader, everything went well, the turn off the phone for putting it on download mode but the phone wont turn on, it doesnt even charge it was dead, hard bricked :crying: ,so i reallyze that all my impatience went wrong and now i have a 900 dlls brick (im from mexico thats whhy is so expensive, a couple months ago) and well the only brigth side is that im going to try guarantee and say that the phone just experience a sudden death case and hopefully the belive me i´ll keep you guys updated! thanks for the support!

first of all, I asked for an Odin screenshot.
second of all, how can the bootloader be locked by Verizon if it's not a Verizon phone? i9300 is an international unlocked phone. If you messed with the bootloader, then I don't think there's anything you can do

Now i have no wifi and no service. I dont have any programs installed on the phone like cyanogenmod, rom manager or clockworkrecovery. I read that some people have it on there phone but i dont have service so i dont know how to install it on phone if i need it to fix this problem.
I did do a lot of searching but cant find the solution. Im thinking about bringing it to a sprint store to see if they can fix it but i thought id try this post as a last solutuion, im really fed up with this problem now. Any detailed help would be much appreciated...thanks
P.S. i went to settings>privacy>factory data reset and that didnt work and it still shows superuser on my phone.
Try flashing original firmware =)
Sent from my LG-P500 using XDA App

Noob problem after root

Hi guys
Sorry but i am a noob to all this so have proberly stupid questions.
After flashing to a customer rom i went back to a stock t-mobile rom. Problem i now face is when i try to download apps from other companies that are not on the app store eg mfortune they are unable to detect the type of phone i am using so i get "sorry we do not currently support your device" despite being able to do so before rooting and flashing. Is there a way i can change this with the release of skyGo on android this month i want to be able to download it. As it will be only on the galaxy s2 and HTC phones for some time i dont really want to wait.
Any help please???
Did you do a full whipe? Adding some details like model number, the rom you flashed and the one you came from may get you some more useful results.
As for the skyGo app, it won't take more than a day for it to pop up as an APK somewhere on the net.
Hello
Thanks for the reply i am currently in work so i cant look at my phone but will update on which firmware and kernal version i am running
I did however follow this guide to root reviews.cnet.co.uk/mobile-phones/how-to-root-your-samsung-galaxy-s2-50004972/[/url]
Not sure if that helps i did not however use the guide to flash the secure kernal maybe thats where i have gone wrong.
I will update the thread with the info later.
Thanks again

NEED HELP!! How to update ROM for International i9300 phone on Fido network!!!???

Hi
So I bought an International i9300 back in the summer and i've been using it Fido (Canada - doesnt support LTE yet)
and i rooted it somehow...dont know how and dont know why lol... and succeeded for whatever its worth... :good:
the last "COUPLE" of months,ive been getting these system update pop ups on my screen ALL the time!!
i've even tried to let my phone update itself but ,im guessing because of my root ,it makes my phone crash half way and forces me to reboot...
Btw,can my root be too old or is it,once its been done its done no matter how long ago you rooted?
anyways long story short,i desperately need to update my rom! the system update pop ups are super annoying and my phone is running on super old 4.0.4 :crying: and the battery SUUUUCKKKKS!!! anyways, im guessing i need a specific rom for an international i9300 running on FIDO? CAN ANYBODY HELP???!!!! IM DESPERATE!! LOL btw i might of been able to root it through ODIN at one point but don't be fooled i suck at these android things yet with a little help (hopefully) i might be able to fix this issue!
I attached a pic of my current situation...hope it help...
Hi,
You can update your rom following the instructions of this topic from "Intratech": http://forum.xda-developers.com/showthread.php?t=1671969
Just follow the instructions, it is pretty simple.
I go to sammobile to get my stock roms (http://www.sammobile.com/firmware/)
On the Intratech topic, you have anything you need to update your device.
Cheers

[Q] Un-root help needed - how can I return to S3 stock?

Hi All,
I'm totally new to rooting and to be honest I never planned to get into it and especially not in this way.... please read on....
I bought a 2nd hand S3. The original owner told me it had been unlocked from Vodafone UK, but no further modifications.
So the phone arrives and I turn it on and the first thing I notice is UltimaROM asking to download their latest v9 ROM. I see other apps installed like SuperuserSU, Headphones shortcut for SGS3, S Note etc... so I suspect the device has indeed been modified. Seller tells me it's only been unlocked and nothing else. Also, comparing to a work colleague's stock S3, my phone has a different appearance (different battery % icon amongst others...), I see Nexus 4 wallpapers are available, JaiThemes etc... all looks a bit fishy to me.
Also phone does boot into recovery mode into CWM...
So I start reading a little bit, I've downloaded Rootchecker - says phone is not rooted.
All I ever wanted was a stock S3, no interest in rooting for now. Could someone please advise what I can do to get back to stock and have it unlocked? I know there are guides to un-root a phone, but rootchecker says my phone is not rooted, and I have no original backup, so I don't know where to go from here....
Any help or guidance is appreciated here...
Check the basics, there's a guide on flashing a stock ROM.
The seller is definitely lying to you

Thanks for the reply.
If I find a Vodafone UK stock ROM, will I then lock the phone back to Vodafone?
Thanks
Don't think so, but why would you get a vodafone ROM? Just get a universal one

Thanks for that, I will look for a universal one.
I've been looking for a bit, but I can't find the 'basics' section you mention in order to flash a stock ROM.
I have searched the forums, and people have mentioned ' I flashed a stock ROM' but I need to know the steps to do this...
Also - has my warranty been affected? If yes and it is now invalid, will flashing a stock ROM solve this?
Again, any help is really appreciated here.

[Q] Help URGENT, deleted system

Hi i need some help please! I was using a ROM (MUI) later i try to install another, but i did a wrong option ( i don't remember actually what is) but now it erase me all the system. when i turn my phone on its only ( samsung galaxy s2 on the screen and nothing happen), also can use lock, volume down and home to downloading mode. i don't know what to do :'(. please some one help me i got a samsung galaxy s2 i9100 im kinda desperate.
i want to know how i can get to stock. please some help URGENT! :crying:
Why on Earth would you do something ridiculously foolish like that ? If you're going to mod your phone, make sure you understand what you're doing before you do it & pay attention.
The help you need is in this thread, and by that I mean do what I told that guy to do (and what Hopper also told him to do). Do not post to the other thread, simply read the help I've provided, and go fix your phone.
I referred you to it because I can't be arsed typing the exact same thing 3 times within 5 minutes (twice is plenty for my level of patience, trust me).

Hi. I am new to this forum but i think i kinda understand what your problem is. I mean a solution since you get to go into the downloading mode. try to use odin to flash the sammy stock rom? Somewhere in xda you can find the tutorial. Good luck.
P/S: Try it/do it at your own risk. not responsible for any damages. :laugh:
