Guest seamie Posted April 12, 2013 Report Share Posted April 12, 2013 Hello, I have just bought brand new g300 from Amazon (under Vodafone umbrella). It has Android 4.0.3. This is my first smartphone so I am really beginner ;-) I'd like to upgrade to 4.2. Should I first unlock that phone and then upgrade or I don't need to unlock it ?

Guest kyan31 Posted April 12, 2013 Report Share Posted April 12, 2013 What do you mean by 'unlock'? Boot loader, or carrier? Link to comment Share on other sites More sharing options...
Guest seamie Posted April 12, 2013 Report Share Posted April 12, 2013 I wanted to use non-vodafone sim card but also upgrade to Android 4.2.2. So 'both' ? Link to comment Share on other sites More sharing options...
Guest kyan31 Posted April 12, 2013 Report Share Posted April 12, 2013 Well, to permanently unlock the phone, your gonna need to purchase an unlock code. Ebay sells them for about £5 a piece :) Link to comment Share on other sites More sharing options...
Guest hippy dave Posted April 12, 2013 Report Share Posted April 12, 2013 And you need to be on a stock rom to use the unlock code, so wait and do that before installing JB etc. Link to comment Share on other sites More sharing options...
Guest seamie Posted April 12, 2013 Report Share Posted April 12, 2013 What is stock rom ? I have just bought it from Vodafone. DO I have stock rom or not ? Link to comment Share on other sites More sharing options...
Guest hippy dave Posted April 12, 2013 Report Share Posted April 12, 2013 Yes you do, stock means the official unchanged rom, as opposed to a custom rom you download from here. Link to comment Share on other sites More sharing options...
Guest seamie Posted April 12, 2013 Report Share Posted April 12, 2013 Can you recommend anyone (cheap but trustworthy :-) ) on Ebay to unlock the phone ? Link to comment Share on other sites More sharing options...
Guest hippy dave Posted April 12, 2013 Report Share Posted April 12, 2013 Well I used korter_gsm, but he's currently not selling anything, so that doesn't help you, sorry. Maybe someone else can recommend. Link to comment Share on other sites More sharing options...
Guest Rico_89 Posted April 12, 2013 Report Share Posted April 12, 2013 I would suggest purchasing the unlock code from ebay as it's cheap and permanently unlocks your phone, so you wont have to think about that any more. Next step would be to "Root" and then Unlock the "Bootloader". Once that is done Install Clock WorkMod. Once you have installed that then make a "Nandroid" backup so you can return to your current point if you want to. You can find all the info on how to Root, Unlock Bootloader and install CWM here: http://www.modaco.com/topic/357243-explained-like-youre-5-install-custom-roms-from-scratch-install-the-official-ics-update-root-more/ Also once you have installed CWM, go here and upgrade it to CWM 6. http://www.modaco.com/topic/359191-recovery-cwm-clockworkmod-recovery-v6027-touch-hybrid-cm-last-updated-1601/ Download the "Touch Hybrid" version labeled "ZIP:" and flash it in CWM itself. IMO start with those things first and then you're set up to install any ICS based rom through CWM. Link to comment Share on other sites More sharing options...

TWRP would probably be a better option for a newbie, it has a very nice GUI with easy to operate controls. Link to comment Share on other sites More sharing options...
Guest seamie Posted April 12, 2013 Report Share Posted April 12, 2013 TWRP would probably be a better option for a newbie, it has a very nice GUI with easy to operate controls. I am not sure if it plays role but I am unix admin (yes - until last week without smatfon ;-) ) but without any knowledge about internals of android etc. If most of the commands are run from a console - that shouldn't be a problem. I just need to improve my "vocabulary" about Android internals since it is quite poor (I had to read what is CWM, etc). Link to comment Share on other sites More sharing options...
Guest shootomanUK Posted April 12, 2013 Report Share Posted April 12, 2013 HUAWEI G300 nck code (sim unlock code) £3.94 from Cellunlockerpro on Ebay http://www.ebay.co.uk/itm/Unlock-Code-Huawei-Blaze-U8510-Titan-U8800-Ascend-G300-U8815-Vodafone-Ideos-X5-/321093368622?pt=LH_DefaultDomain_3&hash=item4ac2a7fb2e Link to comment Share on other sites More sharing options...

Guest Rico_89 Posted April 12, 2013 Report Share Posted April 12, 2013 TWRP would probably be a better option for a newbie, it has a very nice GUI with easy to operate controls. I think he wants to install JB 4.22 so he will need to use CWM 6 which will allow him to get the OTA updates when they're released.. And although the UI isn't Newb friendly, it aint all that hard to figure out especially when the DEVs give instructions on how install their particular rom...

Guest george109 Posted April 12, 2013 Report Share Posted April 12, 2013 If I root and then install new Android - will I loose all installed applications so far ? Yes, You will, as you have to do a factory reset before you flash (install) the ROM Link to comment Share on other sites More sharing options...
Guest seamie Posted April 12, 2013 Report Share Posted April 12, 2013 Yes, You will, as you have to do a factory reset before you flash (install) the ROM Is there any way to save them and then restore ? Or at least make a list of installed software (without writing it on a paper sheet) and use sort of apt-get/yum ;-) ? Link to comment Share on other sites More sharing options...
