Guest penthaler Posted August 31, 2013 Report Share Posted August 31, 2013 OK, this thread is a little warning for those G300 users, which cannot do oficial update via any oficial ROM (update.app) and need zeroing IMEI. Doesnt matter if you do that with 5irom or PC tool, if you restore it, there is one thing you have to know! NEVER RESTORE IMEI BACKUP when you back it up with locked bootloader, in state when you installed any custom ROM (or stock repacked ROM) and using unlocked bootloader. You will brick your phone and cannot ressurect it (no recovery, no possibility to run it in fastboot mode, cannot update via forced update) just only info, that your system has uncertified boot section or something and big orange triangle with ! sign... The main problem is in 5irom app, dont know why, but never had problems with that PC tool for zeroying IMEI. When installed repack of stock ICS B936 ROM, I had still unlocked Bootloader, but need to change first boot screen - so I unluckily used 5irom and very very very old IMEI backup (of course, I did it when bootloader was locked, and the first boot screen stays on huawei)... and... OK - my bad, my stupidity... custom ROM (doesnt matter if custom or stock REPACK) needs to have unlocked bootloader, and if that ROM has not corectly signed boot image, it doesnt matter, till you lock BL... with restoring IMEI I locked it and till that time cannot do nothing. Only sent to warranty, and that I did it last Tuesday... so, take this as a warning or advice, to prevent those troubles that I met with. Will provide you if they "fix" the system, or give me new one or any infos after I will get response from "repair" service. Link to comment Share on other sites More sharing options...
