Guest sharkyo01 Posted June 11, 2013 Report Posted June 11, 2013 try this : http://www.modaco.co...teapp-20032013/ Problems being that he can't access the phone. It does not boot up! I also don't think he has debugging enabled and unknown sources ticked.
Guest penthaler Posted June 11, 2013 Report Posted June 11, 2013 OEM info hack could be used only when phone is running, connected to pc and via phone you have to ALLOW ROOT PERMISSIONS. That is why you get this ERROR on attached pic. If there is no possibility to use any update.app (worldwide / serbia 952 or older GB one) and then you can try anything - what about to try that oficial tool for downgrading from ics to gb? And there is one more possibility. My friend told me, that his SGS3 died, cannot boot it. He bought a HW tool called "JIG" which his SGS3 "resurected" - he was able to boot phone and after that he flashed it... Here is link - sorry, only in CZ language, use Translator http://www.sgs2.cz/clanek/jig-smazn-potadla-aneb-jak-reklamovat-po-rootu Maybe it could help - not sure, working on Samsung Devices, maybe others could do that too... And maybe this could be the last thing to try before sending to warranty... Or send it now, before trying
Guest sharkyo01 Posted June 11, 2013 Report Posted June 11, 2013 (edited) :( I was right ... I have a few hours now let me have a dig around for you see if I can find anything. Did you ever try that serbia rom? http://www.huaweidevice.com/worldwide/downloadCenter.do?method=toDownloadFile&flay=software&softid=NDcwNjQ= - Serbia Rom http://www.huaweidevice.com/worldwide/downloadCenter.do?method=toDownloadFile&flay=software&softid=NDcwMjk= - General Rom Both are worth a shot in the long run!

Guest zordonpl Posted June 11, 2013 Report Posted June 11, 2013 (edited) I've tried both of them. I'm thinking that General Rom is that rom that destroyed phone (Was on G300 when he died) Edited June 11, 2013 by zordonpl
Guest sharkyo01 Posted June 11, 2013 Report Posted June 11, 2013 Is your phone still under warranty? Depending where you are I know in the UK we have a 2 year warranty on ours!
Guest jimsie Posted June 11, 2013 Report Posted June 11, 2013 Have you checked this post? http://www.modaco.com/topic/356806-guide-upgrade-and-downgrade-the-g300-between-gb-ics-and-jb-with-downloads/page__hl__%20upgrade%20%20downgrade Had problems with mine a few months ago, couldn't get any rom to work. Also the rom I used to get it up and running. http://www.huaweidevice.com/worldwide/downloadCenter.do?method=toDownloadFile&flay=software&softid=NDY4ODE= Transfer rom onto root of sd card and initiate update.

That would never work because your on B952 if you think you installed the general rom. Edited June 12, 2013 by sharkyo01
Guest george109 Posted June 14, 2013 Report Posted June 14, 2013 If you hold down power and volume up, what do you see?
Guest joeyla Posted June 24, 2013 Report Posted June 24, 2013 @jimsie the same. update failed I have similar problem with my G300. I'm on Electra ROM but don't think that matters. Turning phone on just displays splash screen. Power on with Vol+ just displays splash screen. Power on with Vol- just displays splash screen. Power on with Vol+/Vol- goes to update but update never finishes. The only way I've been able to get to phone to boot is to remove the battery then connect to USB power. Splash screen displays. I put battery mostly back in but just touch the battery off the spring contacts a few times ( effectively bouncing the battery off the contacts a few times ) The phone will reboot to splash screen usually but sometimes it reboots normally. I may have to try several times but eventually goes past the splash screen and reboots and I gain access to my phone again. I've tried clearing everything possible once getting access again but this still happens when I try to reboot phone ( not always but most times ). But so far I've been able to re-gain access doing it this way...not ideal but only solution I've been able to come up with..... Might be worth a try for anyone stuck on splash screen....let me know if it works for anyone.....
Guest duonghuutrang Posted August 9, 2013 Report Posted August 9, 2013 (edited) I had similar problem, my g300 u8818 in android 2.36, fore update ICS b952 successful, but phone can't start. it still huawei logo bootloop, i can't install any update.app later. what shoud i can do? Edited August 9, 2013 by duonghuutrang
Guest sharkyo01 Posted August 10, 2013 Report Posted August 10, 2013 Can you not access either recovery or fast boot?
Guest duonghuutrang Posted August 11, 2013 Report Posted August 11, 2013 Can you not access either recovery or fast boot? I can access stock recovery and fast boot, please help me,..
Guest sharkyo01 Posted August 11, 2013 Report Posted August 11, 2013 Boot in to recovery and wipe all the caches and see what happens... Also have you unlocked you bootloader?
