problems when upgrading firmware

Hi guys
Just installed the new keies software and it said the froyo update was out for my handset (galaxy s) it downloads the update really slow (takes about 20 mins) and then then after it reaches 100% the phone disconnects from the PC and the andriod constuction logo appears on the phone, then shortly after i get an error message from kies telling me the upgrade didnt work and that an emergancy repair is needed..
Ive managed to recover the phone back to working order, but is there anyway i can get this update?
p.s phone was unlocked with the tool from these forums when we had it, if that makes a differance
There are many problems with kies while upgrading the firmware. When you get the error - did you read the error? At times it says something about a "rapi.dll" file missing or any other file, just download that file and it should work.
Best alternative is download the firmware from samfirmware (stock) and flash through odin, it hardly takes any time.
If you want your genuine network supplied firmware i would use the Kies Registry Patcher as this allows you to save the downloaded rom in case of problems .
Failing that as advised the stock rom but that is not what came with the phone its generic non network non branded .

Click to expand...
Click to collapse
This is not a big deal, just click on emergency when it appears and kies will proceed, it might say that it will download the firmware again or might use the firmware that is already downloaded.
Can somebody point me on kernel for JVQ supporting Voodoo Color? Thanks.

[Q] Ota updates support

Can some help me i am trying to make a new custom rom and trying to integrate ota updates in it all setups were done successfully but when i went to my phone to check whether ota updates are working or not it popped a message - "There was an error with your download" can some one give me the reason of it

[Q] cant update to 4.3

Hey.
I got a notification to update my device this morning so I connected it to WiFi and let it download.
It was very slow for some reason and at about half of the download I had to go, I left the WiFi range and it stopped the download with a message something like that "cant connect to the server please try again", so i tried again and it said that I have the latest update already installed.
Then i tried with KIES, it found a firmware update but failed to actually start the update after the download.
so now i have 4.2.2 and OTA says that the latest update already installed.
I have tried to clear cache, delete all in google service framwork, revert updates for all google stuff, nothing so far
Last thing i want now is to flash it, can I do something to fix this?
The device is Galaxy S4 GT-I9500, stock rom not rooted
Thanks for your time
Same here my friend, I hope someone can give any advice on this.
