I recently rooted the phone and wanted to install a custom rom. When I tried to back up the current stock rooted rom with rom manager, someone went wrong. So I was then stuck on a flashing black screen. But I can still access Odin/download mode. But whenever I try to flash something, it flashes, but the screen just reboots back to the flashing black screen. Help please I dont know what to do
What firmware base did you start from, and what method did you use to root the phone?
Rom Manager is not recommended for use on the I777 phone. You need a custom kernel which contains ClockworkMod Recovery to back up the phone. Did you try to install ClockworkMod Recovery from Rom Manager?
Need more information before we can help. So, answer the above, and provide as much detail in addition as you can.
I almost messed my phone up by not rooting or flashing a ROM the proper (safe) way and ended up using a return to stock / unroot guide to start fresh and just follow the guides for rooting and installing ROMs from there.
Im tired of installing many ROM's and 2 different Recovery, some "cant open .zip" and having boot problems, and in other recovery, it can install roms, but other aslo cant open .zip, and also having boot problems,
Im really tired of reflashing stock ICS Fw then root, install Recovery again, after failing installing ROMs.. its too long to reflash, root, install recovery,, its waste my time and having headache after failing installing ROMs for almost a week
Is there any fast solution or what would you do after you fail installing ROMs and cant boot? even do you can enter recovery? what proper should do next? would you also reflash again stock ICS then root and install recovery?
or any other fast way solution..
Please help
Root and install recovery onto your device. Enter recovery and make a nandroid back up of your device. Flash your new rom and reboot the device. If you boot loop or the rom doesn't work or even if you just don't like it, enter recovery (may have to remove the battery to restart a boot cycle) and use your nandroid back up to restore your device.
Before flashing the new rom, you should make sure that the kernel is compatible with the one that is already on your device. If it isn't compatible, you will also want to flash the new kernel using fastboot/flashtool, and not recovery. Also make sure you have a back up of your rom's current kernel so you can flash the original kernel, if you decide to go backwards.

Thanks I think that what im looking for.. the Nandriod backup..
gota way to find that now and how to install
Thanks a lot!
Hmmm...the most easiest way it to unlock your bootloader first...then flash custom kernel...this can help you skip rooting and installing recovery again and again if something goes wrong cause all custom kernel is pre-rooted and got recovery by default....
next you need to find which custom roms you want to flash...some custom roms have their own kernel or flash any custom kernel that is compatible with the roms....
remember, custom kernel is important cause if you flash the wrong kernel, you might get bootloop after flashing the roms....

Hello All
i recently rooted my Z2 by downgrade method, thinking about moving to CM12 or PA as soon a stable build is released but have some doubts in that area.
1- if i make a nadroid backup through the dual recovery i have now and later after unlocking the bootloader and flashing a differnet recovery and ROM if i restore the old backup will my bootloader be locked automatically?
2- can i use my dual recovery to install a CM ROM( after a clean wipe of current system of course)?
3- i have read about people having problems after installing recovery after flashing a CM ROM, and i havnt really found a coherent answer for that in all the forums that i follow. can anyone give a proper method of how to flash a recovery after the ROM so that i can restore my backup just in case?
4- if my nandroid backup does not relock my bootloader than does restoring my TA backup relocks it?
5- if after flashing a CM or AOSP Rom i try flashing a stock based ROM like existenz or MoonWalker can i restore my TA Backup on dat? will that in anyway affect the root capability of my device? will this relock the bootloader?
Sorry for a list of questions. have only worked with locked bootloader till now and not really handy with sony devices. have only been few months since i got it.
Can someone please remove this thread, by mistake forgot to give a name for this, creating a new thread for same.
Hi,
I have custom ROM installed, I need to know the exact steps to restore the phone as it was stock with recovery and stock eui OS.
like do I need to flash stock recovery first, then flash eui OS or few other steps to make sure I should not lose my IMEIs ?
Thanks
