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.

Ok guys heres the deal....i recently got a samsung fascinate from my sister cause I couldnt mod my inc any more. ok so....i got the phone rooted. i have su perm. i downloaded rom manager and installed it. now heres my problem. i can preform a backup no problem, but when i go to restore that backup it boots into clockwordmod and begins and then get an error about erasing boot img. or something like that. can tell exactly if i get some help from this. also cant install custom roms like i can with my incredible. i know it can be done cause i see roms and all for this phone. can someone please please help me.
Thats because cwm3 will not perform nandroid restores on stock roms. You need to flash cwm 2.5.1.x red recovery. Its the best recovery imo for any bml(touchwiz) rom. Go over to my guide in general section and you cand find cwm 2.5 in section 2&5. Oh and ditch rom manager...manually install cwm via odin!
If you're coming from an incredible, also keep in mind you don't have to be rooted to flash roms either, you just have to have a custom recovery. There aren't really any modifications like rooting procedures, S-OFF, etc, required for rom flashing, just odin a recovery and flash your selected rom.
Hi,
I am unsure about how to flash a ROM on to my phone.
I have already rooted it and installed a insecure kernel using Odin and the Samsung Quick Root tool (found here: http://forum.xda-developers.com/showthread.php?t=1125414). :victory:
I am still running the insecure kernel that I flashed with Odin, and did not install CWM as I do not know what to do.
ROM Manager is installed on the phone but I don't think CWM is actually installed.
Currently, I want to install the F1 Galaxy Nexus ICS ROM. (http://forum.xda-developers.com/showthread.php?t=1601518)
All I want to know is do I need to install CWM, and how to install and flash the ROM to my phone.
The exact model of my phone is i1900-XWLPI.
Thanks.
Hi.
Yes you need cwm.
How to install Rom always be a guide in thread...
Send form Galaxy S2. Using XDA Premium
I was following a guide on it.
Now I am worried
I think it is bricked as it is stuck on the yellow triangle screen.
I don't have a jig and I NEED IT WORKING.:crying:
Ok I managed to get it to go in to d/l mode and flashed kernel back to the one I had earlier.
I think I'll just leave it for today and try another time.
Too much happened today and I don't want to risk a permanent brick.
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....

you do have an alternate recovery, right
most likely very simple...............is it a STATUS 7 ????
if so, you just need to update your recovery.
if you are using CWM, many ROM's suggest TWRP. some are not having problems with CWM, but TWRP is much more user friendly and don't have to mess with vol +/- buttons
You don't need to be rooted to flash a rom.
Either flash from the phone using a custom recovery like ^^^^^ described, or flash from a pc using samsung software (Kies or Odin3).
All custom roms are rooted by the developer.
You know YouTube helps if you think you are having trouble it shows you how to do it.
Hello,
I recently made some mistakes with my Galaxy S2 GT-i9100 while following this a tutorial on Galaxys2root.com (Can't link to the precise article because this is my first post) I flashed the CWM recovery tool linked by this website to my device through the latest version of Odin and afterwards my phone would not turn on. I was able to get into the Clockwork recovery mode however but couldnt install anything because I had forgotten to place any ROMS on my device beforehand. To try and resolve the problem I did a factory reset in the recovery mode but this did not effect anything. I am now unsure what to do next. I would still like to root my phone so that I cant get rid of all the bloatware put on it by Orange mobile as well as update my phone to Kitkat(Currently running Android 2.2) Can someone tell me what I have done wrong and what is the next step for me to take?
Thank you for any help that you can offer
the kernel you flashed it is the problem

is this site you are talking about:
http://galaxys2root.com/cwmtwrp-recovery
im guessing that is the problem(Installing CWM/TWRP recovery will most likely break the ROM you are running currently as it overwrites the ROM’s KERNEL).
If iam right,that means you have to flash another kernel,i suggest Siyah kernel 2.6.14 its for gingerbread version(it has CWM recovery and auto-root):
http://forum.xda-developers.com/showthread.php?t=1263838
after that you can flash the KK rom you want through CWM .
