Guest KasioPC Posted May 8, 2012 Report Share Posted May 8, 2012 After installing the B888 ROM, I tried restoring a nandorid backup. It restored fine, but will now only boot into CWM. I've tried flashing all the Huawei ROMS, but they get stuck on "Update failed" The only one I can get booting is Seb404's debranded ROM flashed via CWM. I think maybe the partitions were somehow changed - anyone have any ideas for this? Link to comment Share on other sites More sharing options...

I think we need someone to post a list of the partition sizes from one not flashed with B888, and compare it with ours. Link to comment Share on other sites More sharing options...

Not sure what the /mnt/asec stuff is looks like a couple of apps I'm running Swannview, Twitplay and Tapatalk. Might be something related to apps stored on the SD card being mounted on launch?

Guest FrankieADZ Posted May 8, 2012 Report Share Posted May 8, 2012 i didnt do any nandorid backup, i wonder if it will affect you if u restore a rom created now u have b888 Link to comment Share on other sites More sharing options...
Guest Frankish Posted May 8, 2012 Report Share Posted May 8, 2012 I'm confused. Can you not just wipe data etc and stick with B888 or does that not boot now? Maybe there is something blocking downgrading? Maybe get a rom dump of B888, copy over the system folder to your system and then wipe data see if that boots?

Nope, cannot flash the B888 ROM the normal way after trying to restore my CWM backup. The partition sizes of /system and /cust are different: Filesystem Size Used Free Blksize /dev 197M 64K 197M 4096 /mnt/asec 197M 0K 197M 4096 /mnt/obb 197M 0K 197M 4096 /system 377M 263M 114M 4096 /data 755M 71M 684M 4096 /cache 188M 4M 184M 4096 /cust 78M 9M 69M 4096 /HWUserData 2G 96K 2G 32768 /mnt/sdcard 1G 477M 925M 4096 Link to comment Share on other sites More sharing options...

Guest FrankieADZ Posted May 8, 2012 Report Share Posted May 8, 2012 ok..so this all means what? we cant flash roms via clockwork unless they are B888 or higher based or something? (i havent a clue tbh..noob) Link to comment Share on other sites More sharing options...

(i havent a clue tbh..noob) The previous ROM Images assume a specific number and size of partitions. This has changed with this update. So to restore to a previous ROM a process to redefine the partitions to the old number and size is needed. Once this process has been written and tested it will be possible to restore the old ROMs. If you look at the partions reported in the posts, there are 2 that seem to be different: System /system partition pre B888 ROM was 295M post B88 is now 377MCustom /cust partition pre B888 ROM was 59M post B88 is now 78M Edited May 8, 2012 by FrownBreaker Link to comment Share on other sites More sharing options...
Guest KasioPC Posted May 8, 2012 Report Share Posted May 8, 2012 Can someone who hasn't flashed B888 reboot into Clockwork, connect via USB and go to 'adb shell' Then type 'parted /dev/block/mmcblk0 print' and post what you get. Link to comment Share on other sites More sharing options...

Guest KasioPC Posted May 8, 2012 Report Share Posted May 8, 2012 Have just tried flashing B888 and it is working fine. Will try selectively restoring bits of my CWM backup and see what happens Link to comment Share on other sites More sharing options...

I'm at at work -no USB access to the phone. parted is runnable from the phone's terminal but says access denied, tried su but the new prompt still says access denied. Is there a way to get terminal access to parted say from recovery, I have CWR installed (at a look but could not see it) I've 3g access at work and the G300 phone, rooted with Seb's CWR. Happy to report back the parted output but cannot run it and no ADB at work. Edited May 8, 2012 by FrownBreaker Link to comment Share on other sites More sharing options...

Unfortunately not, CWR is the only way to access parted, and it needs to be done via ADB as obviously CWR doesn't have a terminal :P Link to comment Share on other sites More sharing options...

I realised after I tried it, although I thought it may have been the ROM messing up the partitions. The fdisk output should hopefully be enough to rebuild the partition table manually - I'll have a crack on my day off (after making a dd backup :P) Link to comment Share on other sites More sharing options...
