Hi
Many customer contact us that have problem while flashing E720. Especially wrong flash with another region file or E720 to E720 Chinese not success. So we decided to write this guide to help customer fix this problem.
Normally we face stop at 98% problem. Below is the way to fix it.
1/ Select Platform "(SGH-E720 NAND Erease)" . The flash. If we get ERR_PROTOCOL after some seconds, that's not problem.
2/ Select Platform SGH-E720 then flash with E720_E720C firmware WITH REPAIR OPTION AND HAVEN'T ANY RESERVED REGION. No matter what this process stop at 98% or not, Continue the next step.
* NOTE : If after flash E720_FIX we get white blinking screen, don't worry *
3/ Flash E720XXEE1 WITH REPAIR OPTION AND HAVEN'T ANY RESERVED REGION. This should success 100%
Finally, it's all OK. Please use Agere Services to rebuilt E720 IMEI.

Yes, I flashed the file E720XXEE without any range in reserved region n with repair mode. It took around 4:20 hrs to cmplete the flashing only to stop at 98% with the error "err_too_many_retries".

I did the way u have asked to do but still the problem has not been solved. Both the screens of the phone r scrambled.

Plz help.

U can use an E810 Com cable + USB2COM adapter, with 921000 flashing speed. Before flashing please choose Platform at SGH-E720 NAND Erease to format NAND first.
Ah, so next night i'll wait for u on MSN (can u online at 10:00PM GMT+5) ? I'll wait for u in MSN . Don't worry. I reveive many many E720 :)

And it's recommand to have E720/P730 original USB cable. Very fast speed flashing + this problem fix.
