Hi Guys,
I have a Nexus S EU version I9023 and I wanted to get ICS. I flashed the 128 mb ICS image manually through fastboot recovery, however, I wanted to go back and try to flash it again or flash 2.3.6 on the phone again but it's not working.
It's going into fastboot and I can choose what I want from the menu but when I choose Recovery, it shows the Google screen, Flashes the Android with a little "Matrix" ball in front of it and then it freezes at a black screen, with the soft buttons lit up.
Could anyone tell me what happened and if it can be fixed?
PS: When I press VolumeUp+Power at the black screen, it resets!

Thing is, I don't have clockworkmod installed at all. It's a clean Nexus S, NO root, NO CWM, no nothing.
I truly hope that somebody will have an answer to this or that, at least, I won't loose any OTA updates from Google by making this update.
The stock ics recovery turns off the backlight on the 9023, it has been explained countless times. Point a flashlight at it and u should be able to see what's actually there.

Exactly. I've had the same problem than OP and fixed it today. Just use a very bright lamp, try to find a good angle and you may see the recovery menu (it's hard to see, you'd better be comfortable with the navigation on the recovery menu as you may not be able to read everything).
it depends what you want to do from here on. the bright light method did not work for me so i installed cwmrecovery with bootloader.
if u are waiting for the next ota, do nothing as you wont need stock recovery to install update.
if you wanna downgrade or flash different rom, you can install cwmrecovery and use that from thr..
no need to access stock recovery
i panicked as well when it happened but ntg to worry about

Guys,
Thank you VERY MUCH for your prompt responses !!! I tried with a bright light and YES, everything is there, I just need to make sure that the angle of the light is right !!!
I can't thank you enough guys and I hope that this thread will help others as well !!!
Thank you once more !
I have the same problem on a I9020. I tried with the bright light, and the screen is blank. What should I do?
I've read all the soft brick threads I could get my hands on. If I missed something, I'm sorry for that in advanced.
Symptoms: When power button held down, "Samsung" appears in white, then switches to the blue glowing "Samsung" won't turn off unless I pull the battery. I cannot access the download menu.
What the [email protected]%$ did I do?: I was following the instructions on this thread http://forum.xda-developers.com/showpost.php?p=28350575&postcount=1 and I finished step 6 and started step 7. On step 7 it wiped the data but froze on the cache. After 2 hours of waiting for it to clear I tried a hard reset and hear I am.
Any ideas to try and fix this? Thank you for your assistance in advance.

Ok but what version?
I am only aware of one version of CWM that works correctly and that's 5.8.1.3. Lots of recoveries seem to have issues wiping the cache which results in soft brick issues.
Follow these steps:
http://www.theandroidsoul.com/touch-clockworkmod-recovery-for-rogers-and-att-skyrocket-sgh-i727/
Then try wiping your cache again, and reboot. If all is well, then re-try the steps to flash Embryo.
Power button isn't stuck.
Sorry, I couldn't access and so don't know what version of cwm but that did look familiar. Was trying Touch Recovery. I'll follow the steps on the link.
That fixed it perfectly. Thank you for your assistance.
Any idea why it wouldn't let me go into the download menu before?

Great, good to hear it's sorted out.
By download menu are you referring to Download mode used with Odin, or recovery menu?
The phone can be finicky with getting into recovery sometimes, I find this exact sequence of steps to always work:
Hold down vol+ and vol-
Hold down power
Wait for phone to vibrate once every 2 seconds
Release power, continue holding vol+ and vol-
Recovery should load.
Otherwise, I have no idea.

Glad to help.
Edit: How did you get into download mode to flash touch CWM 5.8.1.3 if download mode wasn't working? It sounded to me like the phone was bootlooping/locking up due to cache issues. As far as I know download mode can only be accessed starting from a state of OFF and not mid boot if that's what you were trying?

Ahh, live and learn... I had similar issues when I first got this phone and it took me a while to sort it all out. Was extremely happy once I finally got ICS flashed and working though, and now I am a flashaholic.

I've learned quite a bit just by reading development threads for various roms and trying them out, and reading the Q&A forum to see what issues people are having. But there is a lot to learn, I haven't tried any development as of yet..
For the most part just follow steps in the ROM threads verbatim and you should not have too many issues, now that you have a working recovery that is.
Yea, I should do some more reading on here. I love learning this new stuff anyway. I've gotta get to work but thank you for your help. let me know if there are any threads that you found particularly helpful besides the basics. Good night.
hi there,
I'm running CM11 nightly late feb. For no apparent reason my phone went into a boot loop this morning (n.b. I didn't flash a new rom or installed a new app). Now it constantly reboots (literally) and doesn't get further than the CM11 boot video or google logo.
If I press volume down and power, it will head into bootloader - but - I can't navigate beyond 'shut down' or 'restart bootloader'. It doesn't execute two consecutive volume up or down commands. In other words, it's impossible to get into recovery mode. Also, because my phone doesn't boot further than the video or logo, I can't make a fastboot or adb connection via my laptop.
Does anybody know how I can fix this issue? I'm clearly running out of luck. Many thx in advance!
reflash recovery?
Try to boot into recovery with cmd: fastboot boot TWRP.img (TWRP or your current custom recovery)
Then restore a nandroid backup or wipe data/system/dalvik
You can still flash the factory images. Fastboot mode is enough. Guide

The phone doesn't reboot in the bootloader right?
If it doesn't either do what primokorn said or flash the factory image.

Well the issue is that it only stays for a fraction of a second in bootloader, which gives it enough time to navigate one step up or down. Not enough time to get into recovery.
How can I do what Primoken said? It doesn't seem to be possible to do a flash when the phone is constantly rebooting?
Thx for helping me out guys, much appreciated!

Have you ever kept your phone in narrow pocket? Because it's definitely sounds to me like a stuck power button.

It's not a power issue. Also unscrewed my phone to see if that was what caused it. Nothing in there, mechanism functioned correctly.
UPDATE: For some reason my phone booted up out of nothing. I managed to flash an older ROM via CM Updater (through settings)- which seemed to work. Apps were updated and it was running normally. But after a couple of minutes it restarted out of the blue and now back to square one again.
Guess there's a chance I'll probably get a normal start up soon. Is it a good idea to do a factory whipe restart through the settings menu? Or is Primokorn's method safer?

Hi all,
Did a factory data reset with a rooted, bootloader unlocked XT925 on stock jb and now its bricked. I can't access recovery, and when I do the simulated battery pull by pressing both volume keys and power button, it shows the moto dual core screen, before going to the android with the blue bar underneath usually seen while updating for about 30 seconds before briefly flashing the android on its side with the red triangular warning sign above it, then it powers off.
Is there anything I can do to save it? I had modified the start up animation which I think may be causing it. It won't even show up when plugged into my computer.
Thanks
Hi there :
At this point, can you get your xt925 on fastboot mode by pressing volume up and power while it is off? if so, you can just go ahead and flash a 4.1.2 rom. Since your BL is unlocked you can download one from any region that suits you.

i have seen an unusual trend of hard bricks coming from fdr's recently. i cant begin to explain it, or offer a fix for it.
unfortunately from what you have described, your phone seems to be gone.
i can only suggest that anyone having issues with there phone, that they think a fdr would fix, dont do it!! re-flash with rsd instead until we determine what is causing this.
i know its not wide spread, but i wouldnt risk it just the same.

Nope fastboot is inaccessible. Oh well! Sad this happened just before I updated to the loooong awaited KK build as well. Luckily I found a Sony Xperia Z1 for a great price so off to new things (and new subsection of XDA).
Thanks for the replies everyone!
on the other hand Xperia is a good unit

Please relax as all of our phones say that now. I have to say it is quite annoying at times but it will not affect your phone in any negative way. The only coception is that you must watch to make sure you hit the power key when that comes on. If you ever forget it will keep rebooting to that screen and all you have to do is remove the battery and make sure to hit power the next time. I wish there was a way to get rid of it, but the only way is to lock bootloader again. I have never triedbpersonally but have heard it will brick your device because of twrp and the modification to the system. It could be fixed if you decide to try. It would just be a pain in the butt...lol I hope this helps...

XxThat partisa little tricky. From off:
Press & hold both buttons for about two full seconds. At this point release ONLY the power button, but only for half a second. Immediately! press it again (Never let go of volume down) Keep holding until you see a White Screen popup asking to factory reset. Now you can let go of Vol key. Select yes, and then ANOTHER white screen will ask you the same thing, to confirm the first screen. Select yes again. IMMEDIATELY start holding down both vol down and power again. You'll see a warning screen pass by. Let go of power key and quickly press again and hold (never letting go of volume) soon the red lwd light will come on and the splash screen for twrp will start and you re in.
It does take some patience and good timing. In time it becomes second nature and you learn to set up ways to boot directly to recovery from your operating system that way you don't have to do all the key crap. Lol. Make sure when you installed twrp that you removed the battery to power off phone. Also if you have booted your phone to use it without going into twrp first to finish the instructions from the post, which I'm sure you have, i couldn't go without my phone for long. You are going to have to do the install of twrp again. It is very important to boot into twrp first otherwise the stock system will overwrite twrp with it's own recovery again. It sucks but since your boot loader is already unlocked you won't lose all your data this time around. It's just connecting to your computer and using the fast boot commands that you used before. Make sure your twrp.img is in the same folder location as your fastboot\adb and you'll be golden.
Good luck :laugh:

The only thing that I have heard to work is to go back to your rom that you registered your fingerprint on and delete them manually from that rom. So restore your backup and delete from there. If there isn't a backup than I suppose you could try to manually reinstall stock and make new prints and then delete them, then try to switch rom. I'm not sure why that has been a problem and I personally don't use fp to unlock phone, so I am not the best for advice on this. I hope you figure it out
