galaxy s2 displays nothing after logo since flashing cm7 - General Questions and Answers

Hi guys, reasonable newbie here. My Galaxy S2 has stopped displaying anything after the initial logo. In fact it seems to turn the phone off as you can make repeated attempts to boot it within a few seconds.
I started by flashing an insecure sgs2 kernel from this site with odin, then used s2root.
I then played around with rom managed but found it wouldn't boot into clockworkmod (orange exclamation mark in a white triangle every time) I booted into it manually and started trying to flash cm7 which I had downloaded earlier.
I wiped the data etc and flashed the cm7 zip (plus the google apps zip). Rebooted and got into cm7 with everything seeming fine.
Next I thought I should probably flash back to the stock version of the insecure kernel. I rebooted the phone but got distracted and didn't start it up in download mode, I looked just in time to see the normal logo (with the yellow insecure triangle) and then nothing....just blank.
I tried rebooting afew times and nothing, even after yanking the battery. Then I tried getting back into clockworkmod to reflash cm7. Nope, same thing happens.
I can still get back into download mode but nothing I flash makes the slighest difference. Tried reflashing clockworkmod, insecure and stock kernels of various versions but I'm stuck.
This is almost a new phone and I can't believe I've already killed it I would be so grateful for any tips, I've included as much info as I can think of from the top of my head but I will do my best to answer anything you gurus might need.
Again, very grateful for any help...I don't want to have to explain to Orange how I've managed to brick this after 4 days

Ok after trying over and over again to get into recovery mode, it booted into the original (3e) recovery. I've just flash cwmod to it again and have just flash cm7.
After reading some posts about cyanogenmod sometimes not flashing correctly first time, I did it twice (and it did indeed take longer the second time) and twice for google apps.
Next I'll try to get back to the stock kernel. This is where it went wrong before but i'll cross my fingers.
Edit: Well, multiple reboots didn't cause a problem but flashing the stock kernel back does kill the handset again. I'm sure this stuff is all obvious to those with experience I guess I'll have to sit with an insecure kernel and the yellow triangle for the forseeable future. On a side note, s2root doesn't see the phone connected with cm7 (yes usb debugging was turned on). I'm hoping that it is pre-rooted but I haven't tested that yet.

[Q] Samsung Galaxy S i9000 Logo/loading loop? :( help appreciated.

I flashed Bionix-v on my phone the other day, it is a vibrant rom, and I flashed it on my i9000M without knowing this. I liked bionix, but I wanted my old configuration instead, so I restored from my back up with Nandroid. It would work fine until I plug it into either a computer or an outlet, it would immediately power off and have a battery that appears for a split second, then a loading circle, preventing me from connecting to the computer to transfer any type of file. It would continue this cycle until I powered my phone back on again which would say "Vibrant" (I'm using the GT-i9000) then my usual Galaxy S logo. It resumed working.
I decided that I needed a NORMAL charging process so I followed the guides and used Odin to flash my phone back to stock firmware. Odin told me everything succeeded and a giant "PASS" was lit up in green at the top of the window. However my phone no longer had a battery flashing, it was instead just a loading circle that would flash without stop. I unplugged my phone, and was greeted by a "Galaxy S" logo that would flash instead. I have also tried Heimdall by following TubeShaped's : http://forum.xda-developers.com/showpost.php?p=11257871&postcount=154
And tried to flash a custom rom directly from Odin: http://forum.xda-developers.com/showthread.php?t=940671
None of these methods have worked. If any of you have any idea of whats going on, I'd appreciate the help. My hunch is that by loading a custom Vibrant rom onto a GT-i9000, something went amiss, but have no idea what it could be.

P6200 bricked - but sometimes boots and CWM OK?

Hi guys,
Really sorry to ask about this but tearing my hair out!
I have a P6200 UK model. I installed CWM v6.0.1.0 and it worked fine. The intention was to install Galaxy ROM HD (build #06), so I downloaded it, put it on my SD card, and installed from CWM recovery. The install got stuck on "Flashing boot" - so after around 15 mins I reset it.
It went into a boot loop on the initial Samsung logo. Luckily I'd previously re-flashed stock HC with Odin (to cure a dead Wifi problem caused by, I think, an errant install of Busybox) so I did this again, rebooted, and the system came up, text started scrolling up the screen, followed by a red error message (see picture) and a reboot. I was then once again stuck on the initial Samsung Tab 7.0 Plus log. I repeated the process and it didn't even get past the Samsung logo.
So I thought I'd try the newly released ICS Rom (GT-P6200_ATO_P6200XXLQ1_P6200OXALQ1) - this seemed to install OK, then half booted, did some text type installation stuff with the blue Android, then rebooted again, finally getting stuck on the Samsung logo with blue pulsating behind it. It never gets any further than that.
I tried flashing HC back - same result as earlier. I can also reflash CWM and sometimes it works, sometimes it doesn't. It seems I've run out of options.
So - question is - where (if anywhere!) can I go from here?
Help greatly appreciated, many thanks!
have you tried a system wipe in cwm? if not do a system wipe and reflash HC using odin.. same thing happen to me 2 days ago.. I think something is up with HD rom

[SOLVED] Rogers I727R stuck on bootanimation

Sorry everyone... I tried one more time (my 5th attempt!) and it worked this time! I have no idea what happened with the earlier attempts. Thanks
Hello everyone. I'm having a problem with a Rogers Skyrocket here and hope someone can help. It was running a custom ROM, but I was given the task of returning it to stock. I don't recall which ROM was on it, but it worked nicely. I should have just kept it that way!
Thanks to vincom's super helpful posts, I got the info & file(s) needed to get this thing back to stock. I installed Odin 1.85, and extracted
I727RUXLF3_I727RRWCLF3_I727RUXLF3_HOME.tar.md5
from the zip. I started by doing a wipe/factory reset (from inside the custom rom) first, and rebooted to see that it showed the initial setup screen. Then pulled battery and booted the phone into ODIN mode. I made sure to kill Kies completely before connecting the phone to my laptop (WinXP). Then launched Odin, hit the PDA button, loaded up the above file, left the check-boxes as they were, and flashed. It was successful, and rebooted the phone.
The rogers logo appears, and the samsung galaxy bootanimation comes up, and it continues to animate.... forever (for the record, I waited 20 minutes, more than enough time). I can pull the battery and try to boot again but it still stays on the bootanimation. I'm not sure what else to do? I can still get into stock recovery or Odin mode. Can anyone help? Thanks

[Q] Galaxy S2 Soft Bricked after root....

Hi everyone!! New here, but not new to Forums in general. I searched around and couldn't find my exact issue, so I figured I’d start a new thread. This is gonna be kinda long, but I wanna give as many details as I can to keep things accurate.
My wife and I both have the Galaxy S2 T989 (T-Mobile). Both purchased like new off eBay. When I got hers a couple months ago, as soon as I got it I factory reset and wiped the caches, upgraded to JB via Kies, and then turned right around and rooted it via Odin using the instructions found on galaxys2root.com. Everything went flawless, took me less than a half an hour total for everything. I got mine a couple months later and did the exact same process as soon as I got it in the mail. However after rooting on Odin and getting the green pass just like hers, it got stuck in a boot loop when it rebooted. It would go as far as the "galaxy S2" splash screen, and sometimes past that to where the Android takes off, then reboot, or freeze. It then became unresponsive to any button pushes and I had to pull the battery to get it to shut off (The battery is a new OEM Samsung battery incidentally). I ultimately had to unroot, re-install ICS and re-upgrade back to JB via Kies again to get out of the loop. I did this whole process 3 times to make sure it wasn’t something I did. So I’m still running unrooted with JB on it now.
The only thing I noted that was kinda odd was that when I open Rom Manager in my current non rooted state, it shows that I already have CWM and TWRP installed on it. Even though when I go to recovery mode it's the standard OEM Samsung menu. I never installed TWRP, and CWM was only on it for a bit when I was in the boot loop. Could this be my issue? Are they both still somewhere on my phone interfering with each other and I can only see them via ROM manager?
Sorry for such a long first post, and thanks in advance!

hi,
can 'be that your device has some residual old. Do as you have advised. install a stock rom and firmware, so it becomes a new cell phone. After odin starts TWRP (much better) and root.
I would flash a complete bone stock Rom using Odin and start over. Also rom manager was highly discouraged on the AT&T version of the s2 so I don't know what the stance is on T-Mobile's version

Thanks for the advice! Should i flash it back to ICS then try to root again via Odin before i upgrade back to JB? I'm guessing there's something that isn't getting wiped. Since i can run CWM and Root with Odin without a hitch. it's the initial reboot after all that is done that I go into the boot loop.

Sorry for my ignorrance, what exactly is TWRP, and is it now on there because i used Odin and it installed it automaticly? And do i want to use this vice CWM?
One more question...before i try all this, can i backup everything on Kies just like i would be able to with CWM and reinstall if my root fails again? I've only used Kies for firmware upgrade, never to reinstall a backed up copy of my phone.
Thanks!

Hi
TWRP and the 'one touch recovery, better than CWM.
The backup kies can not recover from CWM
steps:
install odin, after recovery, nandroid backup, ROM, and root.
hi
Flash the stock firmware using odin!!..it will work!

freezes then booted
Hello I have this problem with my galaxy s2 i9100. After reboot the phone wasn't booting something like "boot loop" so I re flashed the firmware and now the phone boots up but after the boot it freezes immediately. So I decided to install clock work mod recovery and install cyanogen mode 11 with cyanogen mode the phone boots up and are able to be used again until the screen goes to sleep mode or the power button is pressed then the screen goes black and doesn't turn on after long pressing the power button it reboots. So I don't know what else to do I have tried kernels, operating systems re flashing reseting and nothing helps. No need to tel me to do resettings. Also my galaxy s2 i9100 chip has insane chip bug but I don't know if it has to do something with my problem.

[Q] Nexus 4 softbricked, can't charge

my nexus 4 was on temasek's unofficial cm12 build ver 6.1
recovery in use was recovery-philz_touch_6.59.0-mako
i decided to update the rom to build 6.5, so i downloaded the zip to my sdcard,
i had not made a nandroid bkp
after flashing the rom/gapps/superuser, wiping dalvik and cache, things went wrong
after that the phone would only show 'google', then freeze, then go blank, then again show 'google'. this is the first Loop i have encountered where the boot animation never even showed up.
after that in about 8 hrs, i tried all of the foll-
installing the stock images: my phone booted up the first few times i flashed stock images using fastboot, but after three times (because each time it successfully booted i would go back to recovery to try flashing the customromzip) my phone stopped booting up for stock.
it resolutely stayed stuck on the boot ani.
recovery: flashed many times, via sdcard and also via fastboot. no problem with the recovery
zips. absolute fail. nothing can get me past the 'google'
now there's another peculiarity, which makes me wonder if there is hardware damage involved in this softbrick story
after all this flashing my charge came down to 20%, so i tried to charge it (switched off, obviously, since it isn't booting up)
but every time i connect my charger, it boots up,and then shows me google, and freeze and restart..same old cycle
in a last ditch attempt to somehow charge my phone i have brought it to fastboot, and left it connected to my laptop. i don't know if this will work.
please help, also i am now considering using a toolkit, unified android or wugfresh (the latter, i have a previous bad experience with) to get my phone to atleast switch on with something.
should i use the toolkit or just take my brick to the servicecenter to check for damage to hardware
