What would help other people to post answers for you is if you could list what you have done to solve the problem..There are lost of things you can do but it would be helpful to list what you have done to solve the problem, so that people are not posting answers that you have already tried.. Also don't forget to read the stickies on the subject..:good:

As you have already read and tried all the fixes then you need a service centre repair .

[Q] X10a Boot loop problem

First off please let me state that I am aware that I am not any sort of expert when it comes to this sort of stuff. I might use incorrect terms and say things in a way that displays my ignorance to these extremely technical topics. I am have some good common sense and problem solving skills though so if someone were to offer me some help I can probably 'figure it out' by thinking critically.
I have a X10A with AT&T and was too impatient to wait for SE to come out with the 2.1 update here. When the Nordic update came out I was one of the people that rooted and de-branded my phone so that I could get 2.1 on it. Everything went fine and nothing else seems to be wrong with the phone except the boot loop problem. I can not seem to find a definitive answer as to how to fix this on any forums or anywhere else on the internet. I updated it with SEUS and it did not fix the problem.
Since having done this I have read that all the user data must be wiped before rooting/upgrading otherwise one can get stuck in this boot loop (http://www.xda-developers.com/androi...or-xperia-x10/). I don't know if that is what happened to me or not???? Any help someone could offer would be very much appreciated. Thank you.
So you flashed to nordic when it came out but you just now get a boot loop?
Not sure what happened but I'd say try flashing it. Since you are in a boot loop & can't power on & turn it off to get into flash mode, try THIS
I suggest 2.1.A.0.435 X10a 2.1 Global Generic, there's a nice guide HERE on how to install & optimize it. From there you can install a custom rom if you want or just wait for the 2.3 update from SE or see what our devs come up with in the meantime...
At&t will never give us an update... one of my many complaints with them... I am dropping home & cell services ASAP...
Yes I flashed to Nordic when it came out. I have been in a boot loop ever since. I am just now posting this because I have not had time to deal with it. I had insurance on the phone and just got another one instead of fixing it. I will try your suggestion and let you know how it works out. Thanks for the help!

Do you flashed the correct baseband to your ROM?
Maybe you have to install correct baseband with flashtool.

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

hi thanks for the reply but i think i figured it out. i was looking in other posts and stuff about the same problem and or ones about how to root and i think i just used a out of date kernel thing. because i found the same kerrnel i used that messed up my cell but the other one i found was a newer version i tihnk. so i downloaded that and did the thing with odin and yah it rebooted perfectly and from what i see my cell is rooted.
Good news then

Galaxy S2 i9100 wont reboot after rooting
Hi There,
I have exactly the same problem. I did try to root and followed the instructions given in galaxys2root dot com.
Followed the link "ww.galaxys2root.com/galaxy-s2-root/how-to-root-galaxy-s2-i9100-icsandroid-4-0/" . ( One 'W' is intentionally missing in the referred link as a spoof. I am a new user with less than 10 posts so I am not allowed to paste a working link. Sorry) I went through the video first and followed all instructions threadbare.
Odin returned a green success message too. but the phone would not wake up beyond the Samsung Boot logo for S2. I was on ICS version 4.0.X prior to the ilflated root and my phone version is GT-I9100G.
You must excuse me, I did not note down my previous baseband version and similar other details in the about phone. I bought the phone from a Hongkong based ebay vendor and I live in Australia.
I am hoping i have not lost completely my phone and data. I have written too that web site too. Could you please help as soon as possible. I am without a phone.
thanks heaps in advance,

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

[Q] Upgrade s3 gt-i9300 ic motherboard problem

First of all, hi there. Im a new member and also a noob hehee..
Ok, direct to the questions.
I just upgrade my s3 gt-i9300 to a custom rom and it got softbricked.
I search anywhere to fixed the problem via odin and ota, but still cant fixed it. Pit problem and so on.
After all of the time i wasted, it still not solved and still stuck into samsung logo.
So, i decided to repair it to the technician. The technician said, my phone cant be repair using software , so he's gonna change the 'ic' of the motherboard. The cost is RM250.
The next day, my phone is done repairing.. but now, my phone version is only ics 4.0.4.
So the technican said, my phone cant be upgraded anymore. He said whenever u change the 'ic' of the motherboard, it wont be upgraded anymore.. so i got angry and said, why didnt he tell me before .... so, anyone can help me??? Is that true? Or the technician just troll me so i can send my phone to him and he got money more? Im confused about this.. anyone pls.. thanks a lot..

First of all welcome to xda. I've requested this thread to be moved to the troubleshooting thread cause this is the General thread and not meant for questions such as yours.
As for your question... I don't think he changed your ic just like that he may just have flashed a stock ics rom on your phone so he may had charged you quite a bit. You can always upgrade the 4.3 when you use ODIN if you want to know more there are stickies you can start here http://forum.xda-developers.com/galaxy-s3/help/frequently-questions-t2148708. Also be careful on flashing custom roms always make sure that it's for the GT-I9300 model that you have.

Thank you for your answer. So, can i upgraded my s3?? Coz the technician said that my phone will be damaged if upgraded. I still worry about this. By the way, is it really true that whenever the ic of the motherboard changed, the android can't be upgraded anymore??? Pls help me..
Maybe he changed the motherboard, maybe he didn't. It wasn't repaired properly, leaving it on 4.0 and telling you not to update it means the efs is patched to get it working, this might be your old motherboard with a bad fix or a 'new' motherboard with a bad coding of your imei and serial number.
Either way the technician isn't capable of repairing the phone so best try getting your money back, use the update excuse as a lever.
Leaving the phone on 4.0 will mean sds happens, as that version has a bug that kills the nand memory.
Thank you for answering. Here another question more. So,are there any way to fix my phone? If i upgrade my android to 4.3 will it be damaged?
