[Q] Cannot boot into recovery. Laggy phone as well.

I was just about to try updating from NScollab 1.0.39 to 1.0.40 and for some reason my nexus s refuses to boot into recovery. It doesn't seem to exist anymore. Im not sure if it is related or not but my phone became very laggy after my first failed attempt to boot into recovery. I tried fixing user permissions and rebooting many many times but it doesn't seem to help.

What does it do when u try to boot into recovery?
Sent from my HTC Sensation 4G using XDA App

It doesnt do anything. It just reboots into the bootloader.
Thank you for the quick reply
edit:
i tried flashing recovery again through rom manager and now whenever i try to boot into recovery it just hangs at the google logo with the unlocked padlock.

Hmmm
Do me a quick favor.
go here:
http://wiki.cyanogenmod.com/wiki/Ne...de#Installing_the_ClockworkMod_Recovery_Image
and download the 4.0.0.2 recovery image and save it to some directory on ur computer
then follow these steps:
1. Open up command prompt/terminal and plug in phone to computer
2. Type "adb reboot bootloader"
3. It will take you to fastboot mode. Now type "fastboot erase recovery"
4. Then type fastboot "flash recovery ____.img"
( ____ is the name of the recovery img file)
5. Now it will flash and once it says "OKAY" then scroll down using volume down into recovery and see what happens
plz get back to me bout this!

IT WORKS! It went into recovery! Thank you so so much! Is there anything else I should do or am i set to go?

Thank you so much for the quick help! btw i updated recovery from rom manager and i ran into the same problem with it not booting into recovery so i am guessing there is a problem with the latest version of recovery? I'll just reflash through the instructions you gave me.

Yeah prolly a ROM manager issue

the recovery generally doesnt stick if flashing it through rom manager. flash it through fastboot and itll stick.

Hmm thanks for the advice! ill keep that in mind

[Q] [i9023] Blank/Black screen in recovery

Hey everyone,
Basically I was trying to flash a new ROM onto an old Nexus S of mine and when I tried to boot into recovery there was just a black screen. I pressed the power button and a single line saying "Clockwork mod Recovery" and the version number popped up. I assumed that the recovery must've been corrupted so I erased it and installed the latest version using fastboot which seemed to work fine.
Now whenever I try to boot into recovery I just get a blank screen with nothing else. I've tried using other recovery images such as twrp but the same problem happened, I just get the background wallpaper/image and nothing else.
I searched the forums and apparently people were having this issue earlier on when the i9023 was first released but now most custom recoveries are supposed to work with both i9020 and i9023.
Also the touch buttons light up and vibrate whenever I touch them when I'm in recovery mode.
Any help to this problem would be greatly appreciated as atm I have an old ROM which is buggy as hell and I need to get rid of it.
Cheers!

I had the same Issue. If you can boot into the rom, you can try to download the rommanager-app and install the recovery from there.

Hey I tried that already that and instead of booting into recovery it just went into the bootloader and said "No Recovery or Bootloader found".
Any other ideas?

Did you clicked the first point in rommanager? Install recovery, or you only hit the second button reboot into recovery?

Hey
I have the i9023 and I install rom manager. install CWM and if I reboot into recovery it works and I get in to CWM recovery.. but after reboot into os.. if I go into Rom manager and reboot to recovery it dont work? I just get the android figur and a "!".. then I just can Power + vol up and I'm in bootloader recovery..
Do I have to install CWM every time i want to use it? and can't I access CWM on boot op ?
sorry for my bad English

Normaly you have to flash the recovery only once.
Try to flash the newer clockwork-recovery with fastboot.

Alfiedk: You need to get rid of this file:
/system/etc/install-recovery.sh
As it re-installs the stock recovery every boot.
I think you can download any custom ROM for your phone, and flash it in CWM recovery, this will also solve the problem
Edit: Did you unlock the phone? Have you tried fastboot oem unlock?

I havent unlock my phone, but I can get in to bootloader is it then necessary to unlock ?
I try to delete the /install-recovery.sh

Yes you need to unlock your bootloader, if you dont want to reflash it all the time.

Yes I made sure I selected install clockwork mod. Like I said the problem isn't the same when I do this, instead of a blank screen, when I boot into recovery it goes straight to fastboot and tells me that I don't have a recovery image installed at all...

what happens when you try to temporary boot into the recovery?
instead of "fastboot flash recovery recovery.img", try to "fastboot boot recovery.img"
Just look for an recovery.img that works temporary and then try to flash it permanently.

I'll try it and get back to you Xziped. If anyone else can think of any other ideas please just throw'em at me, I'm willing to try anything!

Yeah no help there either. It does the exact same thing temporarily booting into a recovery that it did when I actually had it installed on the phone :\.
I updated ROM manager to the latest and tried installing CWM with that but to no avail. It still says that there is no recovery installed when I do that.

Sorry but if not even the temporary recovery boots up, i dont know what else we can do
did you try some of the older recoverys? is your bootloader unlocked?

I haven't tried an older recovery and my bootloader is unlocked.
could it be a problem with my computer as opposed to the phone itself? As in my computer is messing up when trying to flash the recovery?
I've also noticed now that when I boot into fastboot mode the menu just locks up and doesn't respond to anything. Sometimes I have to pull the battery and other times it'll start responding after randomly pressing the power key a lot of times...
I'll try an older recovery next

Use Odin, that might solve your problems. Search for the Nexus S version of Odin in the Dev section here.

Place the update.zip on your external sd card.

Wasnt working, got it tho. Installed CWM, flashed it. (After it took me awhile to figure out the CWM Recovery buttons :-/ ) Thanks for the help anyway.

You installed CWM before you flashed it?

Used fastboot to flash the CWM recovery.img then flashed the ICS leak update.zip from the sdcard, I couldn't get it to flash the update.zip without CWM for some reason

So that means the process for unlocking the bootloader for ICS works on HC. Great find (although you almost ended up with a paperweight ).

i did the same as the OP and I've tried the reset button and it doesn't seem to want to work.

Any help would be appreciated.

I can get into APX mode but no fastboot. And as you know you need the CPU ID to get through EUUs, I'm not sure how to get the CPU ID number.

Hello, I have a similar problem, I can enter in APX mode, I have CPUID and I have SBK key but I can not do anything because give me a error like...:can not write to usb....
any idea please?

Can I ask how you got the SBK? That's not available for the A100. The method used for the A500 doesn't work on the A100 bootloader either. If the device is stuck in APX mode then it's bricked and will need to be sent to Acer for repair or a motherboard replacement will need done by yourself or someone you take it to.

[Q] [SOLVED] Flashing recovery.img without fastboot?

Hi all!
My power button is stuck as pressed constantly, and cannot be unstuck.
So there is no way to flash recovery image under fastboot;
nor can I flash CWM recovery TOUCH using ROM Manager, due to network reason that cannot be solved from my aspect;
Flashify said "cannot find recovery block", thus unable to flash by it;
GooManager seems only able to flash TWRP that I decide not to use at present.
So what I want to ask is, is there a way, for our Nexus S, to flash recovery by an Android terminal command? Thanks in advance!

Hello guys. I need your help badly.
I am using Galaxy Grand Prime smg530h
The problem is when I push the power button, my phone automatically boots to recovery mode which is Twrp, yeah I was my only problem last time. I guess I wipe something using twrp, my phone says "NO OS INSTALLED" . Then I googled some ways to fix so I installed a custom rom using twrp. I though my problem was solved but still when I turn on my phone it automatically boots recovery. I googled again and did something. But a big problem shows up, When I turn on my phone, it boots automatically to twrp but after the samsung logo flashes, black screen appears. Its just blank but the my phone black light is on and I think im on twrp since everytime I touch the screen it vibrates.
Please help me

Have you tried to re-install everything including your recovery? Perhaps even your bootloader or try to flash your ROM manually from fastboot or adb.

There is already a guide available for how to flash stock rom, which you can check out here. You can get the stock rom from sammobile, the official samsung firmware resource which you can check out here.
Good luck!
Edit: You can then try to reflash twrp and if it doesn't work, post about it in the twrp thread for your device.

Samsung doesn't use fastboot, they use download mode and flash with Odin. Be familiar with these kinds of specifics about a device if you're going to give advice, otherwise you might tell someone something very wrong unintentionally.

CWM is a dead project, it is no longer supported, that is why you are only finding TWRP. If you want custom recovery, use TWRP, it is a much better recovery than CWM anyway.
