Can't Use Recovery - AT&T Samsung Galaxy S II SGH-I777

I tried to flash CM7 last night but it didn't work so I flashed back to to stock. http://forum.xda-developers.com/showthread.php?t=1313659.
Now when I'm in Recovery mode on my Samsung Galaxy S II a logo of a Black Hat appears when I click on any choice in the Recovery screen and I have to pull the battery to restart the phone. I've tried everything, I think.
Since my phone is almost brand new and everything is backed up, I think, I would like to just wipe the phone clean and reload with the original stock AT&T software or image.
Anyone know how to do this?
BTW.... I think this may have been caused by the fact I tried to use ROM Manager to flash CM7 and on one post it said in big letters NOT to use ROM Manager.
Any/all help is greatly appreciated.

What button are you using to select stuff in CWM?
Have you tried to home button, the power button isn't used in this version

If you have ClockworkMod Recovery 5.0.2.3 in your kernel, you have to use the "home" soft key to select. The power button will only toggle between menu and logo.
To flash back to stock, use one of the one click downloader packages you can find here. You can choose between straight stock, and stock plus root.

[Q] Flashing ROM with Macbook

hello all,
Just flashed this ROM using clockwork, only problem I ran into was clockwork will not reboot into recovery. Instead it reboots into samsung recovery.I would like to re-flash ROM. I am new to this, I was an iPhone user and it was pretty simple to reinstall operating system.
I use a macbook with snow leopard, what is going to be my best option to re-flash with the macbook. I have read about Odin, and ADB. But not really sure which to use or how to use them for just flashing a custom ROM.
Any help would be great!!!!1

Search "boot into recovery"....using buttons.
Power off
Hold vol+/vol- (keep holding)
Hold power (keep holding all three buttons)
Wait vibrant screen...wait for black...wait for second vibrant screen and release power button ONLY.
Should be set.
OR
Search for OS X...you can use Terminal to manually flash/reboot/etc. through utilities. Be careful though, the commands are slightly different.
I'm running OS X 10.4 (tiger) and never have to use the computer (outside of TGA_Gunman's one click root program)...everything can be done through the phone in most cases.
I have no problem getting it in this mode. I am trying to get it to boot into clockwork recovery, and the only thing that is loading is the stock kernal recovery menu.. So I am looking for a method that I can do it with my macbook. I have searched in google, and found other tutorials for other phones, but not the vibrant. If you know of one please let me know..
thanks
in sammy recovery hit 'reinstall packages' (may need to do this more than once) and it will reboot you to clockwork. then flash through clockwork like normal. this is why you need to leave the update.zip file on your sdcard after installing clockwork.

I never removed the zip file from sd card, in fact while looking at the files contained in clockwork mod file. It contains the same files as my other Vibrant that is running fine. Just doesn't have Bionics Obsidian 2.2 running on it..
I tried what you said about clicking on re-install and did that 5-6 times. That didn't improve the problem.
thanks for the idea,
Back to the original Question, what is the easiest way to load different rom on my phone with my macbook?
Does the phone still boot up normally? If so, open Rom Manager and select "Flash ClockworkMod Recovery". Then select your device. Reboot into recovery and if you are still in the stock recovery, hit "Reinstall Packages". If that doesn't work, then I have no idea...

Quirk on different recoveries used ...

When first installed mik's CM7 on my LG P500, it comes with the standard Android System Recovery. I can reach this from holding down the POWER key, and it gives me an option from the drop down menu for (Reboot, Recovery etc.). When you choose Recovery, you get booted to the Android System Recovery menu.
Now, if you launch ROM Manager, and install CWM into your device, you have to launch the CWM recovery from within the ROM Manager app itself. Else, if you use the POWER key, and choose Recovery, you get stuck on the LG logo. There is no way out that I know of. I tried removing the battery etc. but to no avail.
So, I tried the only scenario I know, I booted into EMERGENCY MODE, and recovered the device using KDZ with a Telus firmware load for the LG P500, and gingerbreak the device again, and then re-wiped it and put back mik's CM7 OS on it again.
It was a weird scenario. Anyways, I now only use the ROM Manager and access the CWM recovery from the ROM Manager only.
When holding down the POWER button, I still have the Recovery option shown, but I have not tried to see what happens if I choose it. I did not feel like re-installing all the apps all over etc. Now I have backups just in case.

Many people, including me, have faced issues with ROM manager. Some times when booting into recovery or taking a NAND backup, it performs a full wipe of the phone and it has been reported many times on this forum.
Are you saying that you installed Mik's CM for the first time through the Android recovery? The general procedure is to root -> install CWM recovery(either through ROM manager or through the android recovery) -> install the ROM through the CWM recovery. After this, whenever the 'Power' button is held, the 'boot into recovery' option would directly lead to CWM.
I installed CWM through ROM manager. It successfully installed CWM but wiped the phone completely. Stopped using ROM manager from then onwards.
No. I installed it as you mentioned below
-> The general procedure is to root -> install CWM recovery(either through ROM manager or through the android recovery) -> install the ROM through the CWM recovery.
But when I hold down the 'Power' button, instead of 'boot into recovery' option which I thought would directly lead to CWM, it hanged at the LG Logo. I have not tried it since. I now only go into CWM recovery from the ROM Manager.

If ROM manager works fine for you, then go ahead. It is the easier way to take backup/boot into recovery, but it does not work for me
it is safer to use CWM Recovery than Rom Manager installed on Cm7
Ok, what is the difference? Its the same thing isn't it? I am using CWM recovery but to get to CWM recovery, I am launching ROM Manager and choosing the option to boot to CWM recovery. I am not using the POWER button method option to get to the recovery. I am not certain the POWER button won't work but the last time I did that, I was hit with the stuck on LG Logo.
I did not notice that by holding down the POWER button, I have three options:
- reboot
- recovery
- bootloader
Not sure what the bootloader option does.
Ok
1. Booting to recovery through rom manager sucks because rom manager support for our phone is not correct.
2. Booting to recovery through power menu sucks because reboot in power menu causes an unclean shutdown which can screw with your filesystems.
So, in conclusion, don't use either of these methods, turn off the phone and use the button combination.

Ok. Interesting. Did not know that. I will use the button combination to get into the recovery. It does work for me from the ROM Manager, but who knows how long that might work for if its inconsistent for you guys with the same phone as well?
Thanks guys.

[Q] Ugh, can't get out of recovery 3e now...

I feel like such a n00b but I've literally flashed dozens of ROM's between my Captivate and my Infuse.
Thanks for Entropy, I have my modem back so I can make calls (thank you!).
Now I'm trying to get back into CWM but everytime I flash it in Rom Manager...then reboot into recovery I get this error..
E:failed to verify whole-file signature
E:signature verification failed
And that's in 3e...it won't boot into CWM.
I tried rerooting and using the SGH-I777_ClockwordMod-Reovery_5.0.2.3.tar in Odin...when I reboot in recovery...it freezes up...
Any suggestions?
Hmm that one is odd.
Until further notice - don't use ROM Manager on our device. Kernel-included CWM is the way to go. My guess is that somehow ROM manager dorked up your system partition. You may need to Odin/Heimdall back to stock, then flash codeworkx's CWM kernel, although I'm surprised you weren't able to enter CWM after flashing codeworkx's kernel...
Edit: When you say it "freezes up" - do you mean stuck at the Samsung Galaxy S II screen, or does CWM come up?
If I flash back to stock and try to get into recovery...I get stuck at the above mentioned screen.
If I Odin the CWM 5.0.2.3 package and try to get into recovery...I get into the light blue recovery screen but every option I click on just brings me to the Rom Manager Hat Icon and does nothing (even though I don't have Rom Manager installed anymore). I get stuck in that menu...pull the battery...reboot...still in light blue CWM menu but every option just brings up the Rom Manager Icon.
Only way to "fix" is to get back into download mode, odin back to stock or re-odin the CWM 5.0.2.3 tar again. But, again, if I try to get into recovery from stock...3e recovery (ie useless) if I Odin back to CWM.tar...I get stuck in Rom Manager Icon hell.

Furthermore, the first day I had the phone, I used Rom Manager to install MUIU and it worked fine! Except I had the wrong modem (which I just found out today). I thought MIUI screwed up my phone (because I was unable to make calls) so I then flashed back to stock. Luckily someone posted the stock modem up and I installed that...phone works fine.
I'd like to get MIUI on again because it was smooth as butter and all I did is download the Rom Manager version...i Know it's not supposed to work but it did.

Might be because the buttons aren't the same as they are on the Captivate and each time you hit power or menu (which used to be select on the Captivate) it kinda blanks out the menu until you press it again. Use the volume keys to move up and down, home button to select, and back button to go back.
whoa, I'm retarded...that worked...thanks!
Yeah I was losing my mind too when I was first trying to flash Cognition. Just started mashing buttons and got lucky

I9100 roms will work to an extent, but like you noticed there roms do not support our modems or capacitive keys. Could be other things that are unsupported as well.

This is correct - it's why you see a bunch of posts between myself, codeworkx, and atinm in the CWM thread.
The current behavior is a bit odd, but it is usable, it's just not documented properly right now.
I have a similar problem, I've found that whenever I get that message, and none of the options on cwm work I pull the battery and turn it back on and the install resumes. Not sure why it hangs up like that but its led to a few tense moments already

Can't enter cwm recovery/perform nandroid restore

Hi, I have this problem. I had rooted galaxy S3 i9300, with Android Revolution ROM. I wanted to flash Liquid Smooth ROM and I did something wrong because I soft bricked it. So I downloaded some stock ROM (Not the one I used to have, completely different one with older android I didn't notice version I looked for region) flashed it with Odin, then rooted phone with Odin and flashed CWM with Odin, so I could do nandroid restore of the older ROM I had. The problem is I can't get to CWM recovery. When I turn on phone while holding Vol-, Home and Power buttons, I don't see Samsung logo, I get straight to download mode. Somewhere I read that you need to install CWM first and then root, so I did that as well and it didn't help. Can I restore my backups some other way? Or what should I do?
Edit: I installed ROM manager and tried to install CWM. It downloaded and then I got Flashing 100/100 and nothing happened. It froze and CWM was not installed. Then I found app CWM (idk if it was there before I didn't notice it) So I tried to restore backup with that and it did not worked as well.
Actually I wouldn't mind using this older version, I would say it's faster than newer one, but my network is not working. No signal so I need to repair that fast bc I don't have any other backup phone.
I'd say your best bet would be to try:
Flashing your stock rom again using odin.
Let it reboot and load, then switch it off.
Go back into download mode and flash cwm or philz touch or whatever custom recovery you choose. Make sure you untick the reboot when finished option in odin or else the phone will revert back to stock recovery.
Unplug the phone and pull the battery.
Hold down the vol+ / home / power button for about 5 seconds and then let the power button go. This should load the recovery. Reboot from recovery and it should be a permanent fix.
I'd then root and apply supersu and then install a custom power menu (xposed module + gravitybox) which allows you to boot into recovery/download mode straight from the power menu.
Good luck.
I did what you said, installed stock ROM, right one (I guess), flashed cwm, unticked reboot, after that I unplugged phone and pulled out battery. And now, if I try to enter recovery I just enter download mode again. Idk what did I do wrong?

LG G5 H850 Unrooting and updating android?

Hello,
I got a little problem with my lg g5.. I've unrooted my phone for a couple weeks ago to try and update to the latests version of android but I'm stuck at the part of updating.
Currently my phone is running android version 6.0.1 but I've seen that there is a newer version and I would love to install it on my phone but the notification that is popping up every day is nog working.
Hope somebody can help me.. Im really bad at this kinda things.
Do you have TWRP installed as a custom recovery? If so I understand your need to flash the default recovery img or updating from the phone will fail on reboot.
Check our autoprime's all in one guide that might help you troubleshoot and restore your phone to MM or N

Is there a way to check what custom recovery I've installed? It's been a while since I rooted my phone..
Turn off the phone or remove the battery. Then, hold down the volume down button and then the power button. Keep them both held till you see the LG logo, then release the power button and briefly press and hold the power button again. If successful you should see a white, factory restore menu. Use the volume keys to navigate and the power button to select yes on both the two screens. NB if you do not have a custom recovery this will factory restore your phone-so make a backup. If you do have a custom recovery, it should boot up e.g TWRP
From here you can flash the default boot loader img and then update ota

When I restart my phone and use those keys my phone is booting into the white screen where I can go into factory restore.. Do I need to install a custom recovery first?
Once in the white screen, to see if you do have a custom recovery installed, you need to select yes on both screens to enter the custom recovery. As I said before, if you do not have a custom recovery (such as TWRP) you will factory reset your phone and lose all settings so make backups first.
Before all that though, how did you root and into it your phone- that will give me an idea as to if you have a custom recovery installed

I've been using the bootloader unlock from this link
So you most likely flashed TWRP if you followed the instructions verbatim. How did in root?

Flashed the SuperSU with TWRP, it's down below at the tutorial page.
Now I only need to know what I need for the stock recovery and how I can update my phone
For the stock recovery, I have 6.01 10E stock recovery here https://drive.google.com/file/d/0B3j5Gs11w3EqVzNwa0h3b2tVWmc/view?usp=drivesdk
Hopefully that should work. If not, you can extract the recovery image from the full zips on autoprime's all in one LG g5 post.
Good luck
Hope I will get it working xD Thanks for your help!
