I recently flashed ICS 4.0.3 on my Nexus S, and now when I enter Recovery it shows me the Android guy lying on his back with his chest open and having an exclamation mark on top and then the screens turns off.
I tried using a flashlight to read the screen and I tried re-flashing the 4.0.3 but to no success. I wanted to use ClocworkMod's ROM manager to boot but it says my phone is not rooted.
The phone was rooted when I had 2.3.6, but since I've updated I didn't root again.
I looked around the forum and I saw something about fastboot, but I'm a n00b when it comes to these things and I don't know how to use it..
Any idea on how to make it go into Recovery mode again? Thanks
While your phone is off; hold the power button and hold the volume up button, then you should be in recovery.

I've done that, I used a flashlight and tried to flash ICS all-over again, but nothing flashes...anything else?
Same problem
A friend of mine has the same problem unrooted stock 4.0.3 when he boots in to recovery black screen. Tried using a torch (flashlight) to see the screen but couldn't see anything on it.
A bit of research has found this section and just trying to find bright lamp to see if works as per a few of the posts on the link below
http://forum.xda-developers.com/showthread.php?t=1396615
and yes you can just see the text, we have used a bright lamp at different angles but not managed to do the 4.0.4 update yet...
Cheers
I've already used a flashlight and I could see part of the menu. I tried re-flashing the ICS update to 4.0.4 and the original 4.0.3 ROM, but still nothing. I couldn't tell what error it had or it said. I want to know how can I root again and try to install the ROM from ROM manager?

I remebered I saw this dead droid and seems like need to go into fastboot and download custom recovery again.
I think you should try to load in custome recovery. That is what happen to me and able to have a live droid.
When you see the android guy lying down with his chest open, just hold the power button and push the volume up button, then let it go and you should be in the bootloader menu. Then just use the volume buttons to move it down to recovery, then click install zip from sd card.

I tried that, it doesn't work (i tried flashing 2 ROMs and it didn't do anything to the phone). What custom recovery would you recommend?
Flash back to stock I guess
fastboot flash recovery recovery.img

Anyone can recomend a good ICS 4.0.4 ROM?

I can recommend AOSP+. It's very stable and fast (ROM benchmark 2nd place). It is very stockish, I LOVE IT. The developer is also involved in CodeName Android, a highly customizable ROM, they should update to 4.0.4 soon. If you like STOCK you should go with AOSP+, if you want more options for customization you can install CodeName in version 1.6 or wait for the Update on 4.0.4.
Also very good is Pete's Bugless Beast and Brainmaster's Stock 4.0.4
last night I got OTA for 4.0.4...dk how since I have root. I installed it and it runs sweet. thx for the help guys
how???
do u ve a phone bought in india...i have i9023 carrier airtel chennai india....i am still in 4.0.3 stock rom but manually updated....

You can just inter to bootloader, and reflash the recovery image with fastboot tools.

I have been running on the gb 2.3.3 rom (rooted) that I have flashed using odin back in summer and now decided to do some more upgrading . So I found a new rom that was very intriguing to me: http://forum.xda-developers.com/showthread.php?t=1305145 After doing some research I realized I needed to do a different type of flashing (cwm?), and not through odin. So I downloaded root explorer into my phone and followed the procedures in this forum: http://forum.xda-developers.com/showthread.php?t=1122508 but every time I try to put my phone in the recovery mode (holding volume up + down + power) it wouldn't go into the blue screen. Instead, it would just restart, and restart, etc.. Any suggestions? Do I need to do something with the kernels?
p.s.hahah after messing around and looking through forums all day, I got a little impatient and flashed gb 2.3.6 using odin in the mean time

Try this.
Basically do what youre doing but instead of keeping on holding to it, hold on to Volup+voldown+power for 2 reboots, then on the 3rd reboot, the gs4g screen in the beginning lights up a slight lighter than usual. Let go of the power button, See if this works.

Hi I have the same problem but I still cant get into recovery, I go straight into Download mode. Please Help
It might be because your phone is connected to the computer? If so, try disconnecting it

This thread says the original GB rom changed the key mapping. Any ideas on where I can find a fix. I think thats what happened to me.
hmm I'm still relativley new to this kind of stuff as well, so the only route I know that you can do that will most likley fix the problem is to odin to a newer rom, perhaps the one I have linked above, then odin the kernal as well to get it rooted and follow the guide on how to do it if you're confused. Then turn off your phone, hold (volume up + volume down + power), screen should boot up then dissapear, boot up again, then disappear, and on the third boot up, just release the power button but continue holding on to the volume up + volume down buttons and just wait. The cwm screen should come up from what I experienced on two different sgs4g's. Hope that helps somewhat lol. I'm sure there might be a easier way to just fix the key mapping but I'm not to sure on how to do it. gl
I just verified that method works for me as well. I'm lazy, though, and downloaded Quick Boot from the app store as it lets you boot into recovery or download mode. Less fuss.
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

Hello. I tried using the search button, but couldnt find anything. Sorry if I didnt look far enough into this before posting.
I have an Inspire 4g, and 2 days ago I rooted it, so that I may instal the sound mod. Im still running the stock rom. Well tonight, I tried to do a factory update, and now my phone is frozen. On the screen is a white triangle, with a yellow exclamation point in the middle and the droid robot below it. How do I fix this? Im trying to not freak out, as this is my first "smart phone".
Please help!
Thanks Chris
What do you exactly mean with "factory update". Do you mean OTA update or did you flash RUU?
Phone is just propably in recovery mode. If it has been there for long time, pull battery out and reinsert it and try to boot.

If I recall correctly when your rooted you are NOT suppose to OTA update from carrier. You suppose to wait for the rooted version from XDA Devs and flash it.
Sent from my Inspire 4G using xda premium
Yeah, you're never supposed to update OTA from AT&T if you're rooted. Unfortunately you learned this the hard way . I'm not 100% sure of the fix, but the go to move always is try to get into HBOOT. Do this by turning of the phone and then press the vol. down rocker button and the power button at the same time. If you can get into HBOOT then you'll be able to get into recovery to flash a new ROM or restore a back-up.

Chris, do as Bacon told you...try booting into hboot (Power + volume down) and check if you are still S-OFF (on the left corner you will see ACE PVT S-OFF or S-ON) if you are still S-OFF then you will have to try to flash a recovery image...
Chris,
I had the same issue when I first rooted. The process discussed above should fix it if you have a rom to flash on your sdcard, if you don't have a flashable rom, or can't access your sdcard through usb storage in your phone, pull your sdcard and put it into a reader to load a rom, then flash the rom using the instructions found in any number of threads about flashing custom roms. I am using IceColdSandwich v 4.2 and like it very much. Good luck.
Hello XDA-community,
I got a nexus s, i rooted the phone and got a custum rom up and running.
then i decieded to flash a new kernel.
Once done, i rebooted my phone.
The screen turns on, but stays all black,
I cant boot into recovery (volume up + power)
If let the phone on for 10 mins to see if it boots up, but nothing, i tried to dial my number on a other phone but got me straight to voicemail.
If i put the phone on the charger the screen turns on, But stays all black too.
I searched xda and other sites but could not find a solution, help appreciated.

I cant flash anything thats the problem,
i had cm9.1 on it : downloaded from cyanomod website.
Android started up, everything was working, but i wanted to flash a other kernel: TNS132-JB-ALPHA12 found on ( i cant post links becouse i am a new user)
got a new problem: screen wont turn on at all only when i put the phone on the charger it turns on, but all i see is a black screen.
I have not made a backup whatsoever, i even didnt clear cache when installing new kernel.
I know i am a totally noob, its becouse i have owned a hd2 and i could do anything with that device wich was unbrickable.
the first mistake was not reading here for 4 or 5 days
prior to jacking your phone up
since you probably need your phone befor that...
pull the battery
put it back
hold vol. up and hit the power button
boot to recovery
reflash the rom you had working
now
rectify the first mistake...
By the looks of it you've flashed a Jellybean kernel on an ICS ROM.

You need to use adb to push an ICS compatible kernel on to your phone, then flash it. Like someone said earlier, your kernel is meant for jellybean (android 4.1), and your ROM is based off of ice cream sandwich (android 4.0). If you've never used adb, look up a guide here in the nexus s forums on xda, I'd link you but I'm on the mobile app so I cant.

Good evening all?
Ive unlocked my TF300T a year back and had been running Cyogenmod 10.1 on it for months, all worked fine.
As a recovery i had CWM installed and it worked like a charm as well.
A week ago i saw Cyogenmod 10.2 was out there and i wanted to switch the recovery to TWRP (i installed ver 2.6.x.x) and tried the new Cyogenmod.
It sisnt work so i wanted to switch back to 10.1 and CWM.
I dont exactly know what i did but in the end even the vol down and power button menu doesnt work anymore.
The tab turn on now and shows the Asus start screen but doesnt boot up.
Also when i press vol down and the power button it doesnt load the boot menu where i can install a new recovery and install the old Cyogenmod.
When its powered on i cant even turn of the tab, it keeps turning on for a few minutes in the Asus logo screen and than turn off and on again... till the battery is empty.
Did i brick my tablet ?
Are there any ways i can try to get the original software back?
Any help would be greatly appreciated.
Cheers !

I think i didn't...
At first i just unlocked the device, installed recovery CWM and after a version (januari 2013) of Cyogenmod 10.1 wich was Android 4.2.2 and kept the Cyogenmod 10.1 up to date every few weeks... Thats all i did till i wanted to install Cyogenmod 10.2 (Android 4.3)
I can't recall updating the bootloader myself, could have been with an Asus update or something but i think i din't do it myself.
CM changed to the updated PITs when Asus updated first.
best solution would be to flash latest stock, boot into it once, flash twrp2 (2.6.0.0 works for me atm) then flash cm10.2
here is my summary

and no, i don't think you need to send it in for repair - it sounds more like broken PIT's so mount and boot points are not being recognized anymore.

More details will be needed before someone can help. What had you done right before it acted up? What rom do you have in there ATM? Can you post a picture or tell what's on the initial screen (the one before the boot animation)? Did you try volume down + power? If you did, what did the screen show?

I rooted my device using the method shown on this page
http://forum.xda-developers.com/showthread.php?t=2228613I
, the ROM is stock and the screen before the animation is normal (white Asus text). I have tried volume down and power and from that screen, I reset my tablet. This didn't solve the issue, before this started, I changed the boot animation and changed fonts. I think it was while restarting after the font change that it stopped booting properly.

I gather by "reset my tablet", you meant you cold booted it by selecting the android icon. This being the case, you can always reflash the stock ROM with fastboot. Depending on whether you had 4.1 or 4.2 bootloader - 4.1 has 4 icons including a USB icon which if clicked, will make the tab enter fastboot/download mode; 4.2 will enter that mode automatically as you press volume down+power - you need to choose the right ROM you want to install. The initial screen should tell you which bootloader on the top left corner. 4.1 matches stock Roms commencing with 10.4.x.xx; 4.2 is Roms with 10.6.x.xx
I've flashed a 4.1 ROM (104220) on a tab with 4.2 bootloader by means of an external SD card without problems. However, to be safe, you should flash whatever version you'd had before the incident. If you already have data on the tab that you care to keep, you shouldn't touch the wipe date icon. If you need a link as to what to do, read this one. Good luck.
