Yes same problem with me also...i've downloaded 6times but after rebooting it is saying "could not update"
I also have this problem.
I rooted my Arc yesterday, then updated to 2.3.3, but now I cannot update to newer versions via WiFi or OTA, it just gives me a message saying 'you must use a computer to update your phone'.
If I do as it says will this damage the phones firmware, unroot my phone or just simply work???
Help plz???
Hellooo, its mentioned many times in the General section of the Arc forum that the Generic.181 is not used for OTA to .368
You must flash either HK.181 or Generic_UK.184 otherwise it will not work...
and then after you flash you loos every thing just perfect I'm beginning to think rooting my phone was a waist of time .

Look at threads in general section, we now have Root for 2.3.4
Downgrade to the UK rom 2.3.2 with Flashtool -> Gingerbreak -> OTA update via WiFi ( as in some coutries UK rom restricts Data (2g/3g) connection untill the correctconfig is obtained.. But if you keep it running on WiFi they will selv-download )
And it's not a waste of time.. i've had my Arc for just some hours out of the box and did this in halv an hour.. If you use Alternative Messaging app, Homescreen app and contacts app... You can backup the needed things.. So no problem at all reflashing.. just reflash and restore
Have fun with your FreeToBePhone!
wait for a while...
i wait..and today i was able to update 2.3.4 (build number .283)
over OTA..and root remain..
just to say...
before OTA i had 2.3.3 (.145)...i was downgrade to 2.3.2 to gain root and OTA...
after few day again OTA (not downgrade) and here i am
Ok I too followed the guide, I'm rooted on 2.3.2 (.181). From my research it looks like I used the wrong file when I flashed the phone. Can someone please send me the link to the correct file?

Are you using Xposed? Xposed modifies your system partition and OTAs don't work with a modified /system. Open Xposed and uninstall all of the modules, then uninstall Xposed. The OTA should work for you then.

G928a drk fix after updating to marshmallow

hello guys,
recently i was trying to update my phone from android 5.1.1 to 6.0.1, i have a problem with my phone aparently the one who sold me the phone changed the imei and when i update my phone got stuck on the android system recovery screen and at the bottom of the screen i had a message about "DRM FAILED CHECK YOUR DRK FIRST".
well after a few days of investigation i found a solution that i would like to share, since i havent found any other thread about fixing this phone directly.
ok instructions:
- Download the stock rom 5.1.1
link (http://forum.xda-developers.com/s6-...-edge-plus-t3194607/post66036193#post66036193)
- Flash a Custom Kernel
link (http://forum.xda-developers.com/att...t/g920a-g925a-g928a-kernel-auto-root-t3329792).
like you see for this you have to downgrade to 5.1.1 but in my opinion is better than have the phone not working at all.
Any question do not hesitate to ask.
