[Q] My Nexus S cannot boot

Hello,
I was trying to root my Nexus S, and in the mean time don't know what failed, but now I cannot boot.
If I boot normally, pressing the power button, it gets stucks in the screen showing "Google" and nothing happens.
I can access the recovery menu if I press the volume up button while pressing the power button. I tried to reload images and recover from them, but it always get stucks in the image of the android with the exclamation.
My question is, does any of you know how I can repair my booting? At this point I don't care if I lose the root or not.
Thank you!

The exclamation is probably the stock recovery do you know how to use ADB
Sent from my HTC Desire HD using XDA App

yes, I know how to use it, not an expert but i know how to use it.

try this

seems like you never flashed to stock or bad flash try full wipe and flash either rooted stock or custom rom

Didn't help, no useful solution in that thread, however will keep an eye there if something new comes up.
Anyone experienced the same problem ?

but from root and stuck on bootloop you might need to reflash the rooted stock rom. it is usually PDxx.IMG what root method did you use? did you get any errors?

I got no errors.
I already tried to flash with several differents .img, but none worked so far... I tried really a lot differents. Always get stuck at booting.

Hello!
If you see the triangle and ! when you go into recovery, then you just need to flash clockworkmod recovery. Then you can flash a ROM.

if your in clockwork do full wipe then flash new img i always do this order
-mounts and storage
-format /cache
-format /data
-format /system
-back to advanced
-wipe dalvik cache
-wipe battery stats
-*****go back****
-wipe data/factory reset
-now flash rom

already tried, didn't work... nothing happens

the same happens, still get stuck during booting....

after wipe do you see rom install

Boot stuck

Today I tried doing the box.net trick to get 50gb free, so I editted my build.prop, then I rebooted. But it got stuck at the Galaxy Tab plus screen. So I tried reflashing via Odin. Now it booted, but now it is stuck at the Samsung boot screen.
So now I am running out of options, I tried mounting USB, but errors keep showing up. Please help. Thanks.
EDIT: Just to add on, using P6200.

I did attempt that as well, now waiting for boot in the past 15 minutes.
EDIT: Tried 3 firmwares, and all didn't work out.
Anyway maybe I had some useful information. Apparently I could not mount my internal SD card for some reason. So does wiping my internal SD help?

OK managed to salvage the situations. Thanks anyway. :victory:

[Q] Trouble with flashing Cyanogenmod 7.2 (status 7, installation aborted)

Hi, I have a Galaxy Ace GT-S5830M. I flashed the CWM Recovery v5.0.2.6 successfully. In the Recovery mode, it says "ClockworkMod Recovery v5.0.2.6." I wiped everything after a reboot. Then I tried to flash the Cyanogenmod 7 Nightly Cooper but I kept getting "(Status 7), Installation aborted."
I did Show log, along with other things I couldn't understand, this is what got: "Error in /sdcard/Apps/cm-7-20120826-NIGHTLY-Copper.zip," followed by status 7.
I don't know what to do or where to go from here. So if anyone has any advice, I'm all ears.

Does anyone know a solution to this problem, please?

Try downloading the Rom Again!, maybe it is corrupt, also try asking support in the ROM thread.

To do the following you need WinRAR, and Notepad++ (download here)
1.- Open the ROM with WinRAR, and go to META-INF/com/google/android and then double click updater-script. Open it with Notepad++.
2.- Delete the first 2 lines of the updater-script
3.- Save, then WinRAr will tell you that updater-scipt has been modified. Click Yes.
4.- Put it in your SDCard, and flash it now.
Press the Thanks button if helped.

Setup Wizard
@ImSoBored:
I followed the steps and did the flash again. The installation was successful, rebooted then flashed gapps, rebooted. After logo screen, I arrived at the same problem I was facing before:
Setup Wizard
Sorry!
The application Setup Wizard (process com.android.setupwizard) has stopped unexpectedly. Please try again.
Would Odin help? I tried Odin, but never got the phone to enter download mode. I held Volume Down+Home and tapped Power button and nothing happened. If I held all 3 keys together, the phone would just boot normally.
Also, is CMW for S5830i compatible with S5830M? Because I might have flashed the S5830i version.

Please press the Thanks button, I solved your first problem ^^
I doubt flashing with ODIN will help, do you know how to use ADB?
In terms of the CWM, I think there's no problem, since in here it says the S5830i and s5830M are exactly the same. Moreover, if you can use without any problem CWM, I don't think there's nothing wrong.

Thanks for the tahnks, now, do you know how to use ADB?

Wipe data, wipe cache partition, wipe dalvik cache (under advanced) and reboot. That should work on a boot loop. If not say me. Do you know how to use ADB?

The "wipe date/partition/dalvik cache did not work, but I odin flashed it back to factory setting. I still don't know what ADB is or how to use it. By the way, is there a working/compatible version of Cyanogenmod for Galaxy Ace S5830i or S5830M?

[Q] Phone Beyond Repair? Please HELP!

Hi All,
I think my phone may be done for, but I wanted to ask all of you first. It all started when I booted up my phone, and it went into Stock GB and before I could do anything at all, everything started force closing (i.e. twlauncher, clock, 10 other things etc.) basically the entire OS and the phone would reboot and then again same problem. Sometimes it would get stuck on the ATT "Rethink Possible" screen for a while, and then immediately it would get to the Your phone is locked screen, and everything would be force closing again. I booted up into recovery mode and wiped user data and cache. Nothing. So then I decided to re load the firmware using jscott's completely stock rom. I used ODIN with PIT, PDA, and Phone and let it do its thing. PASS. Once again, phone did the SAME thing over and over. I then thought let me try either a custom ROM or rooted stock GB. I used jscott's "I997UCLB3-CWM-root-deodex.rar" and used ODIN. PASS. Cleared user data, cache, dalvik. Tried to boot. Still SAME problem. Then I thought maybe I could load ICS Custom ROM and fix the issue (a stretch I know, but no idea what else to do). So, I used ADB to push "Infinitum" ICS ROM to the /sdcard Booted to CWM Recovery and installed the zip. The phone rebooted with the blue android logo and then once again, got to the welcome screen and everything started force closing and the phone rebooted.
Am I just out of luck? Any advise would be greatly appreciated. Thanks in advance.

Ok, I did that as well. Same thing happens. Everything completes successfully on the Heimdall 1 click, but when it boots, same problem...
I tried multiple times with multiple computers.
I also tried GTG Unbrick complete stock as well just in case. Same thing...
Anyone else know what I can try / do?

I would suggest formatting EVERYTHING except the boot partition on the phone and try again to stock. Something is screwed up and is causing the force closes. If you do that and it STILL does this, then there is a hardware failure that is most likely causing the issue.

Yes, I can get into recovery or download mode.
When I ODIN or Heimdall into the stock, I have 3e recovery. If / When I add CWM entropy kernel then I have CWM red recovery mode.
I have tried wipe user data, cache, dalvik cache, etc. to no avail.

There should be a mounts and storage menu where you can format stuff. Format EVERYTHING except the BOOT partition. IF you format boot you are screwed! Also if you have IMPORTANT info on the external or internal SD card back that up first!!!!!

Oh yes, I have done that several times already. I have mounted everything and then proceeded to format them all. It does keep telling me that sd-ext is not found... (not sure if that is normal)
So to recap, I have tried installing / flashing with the following:
ODIN GTG UCKD5: http://forum.xda-developers.com/showthread.php?t=1116251 Flash PASS - same problem exists
ODIN JScott UCLB3: http://forum.xda-developers.com/showthread.php?t=1705260 Flash PASS - same problem exists

ODIN JScott UCLB3 Rooted CWM (Entropy's Daily Driver): http://forum.xda-developers.com/showthread.php?t=1613523 Flash PASS - same problem exists
CWM Install ROM Infinity ICS - Successful Install - same problem exists
CWM Install ROM SlimBean (Jelly Bean) - Successful Install - same problem exits
Problem occurs no matter how many data/factory reset wipes I do. As soon as OS boots, everything immediately starts force closing (I can see the welcome screen, but can't get to it with all the force closes on top).
Example of some of the force closes: "android.process.acore has stopped" & "com.google.process.gapps has stopped", etc.
Ran EMMC Brick Find: http://forum.xda-developers.com/showthread.php?t=1823918 and it went through each MB up to 16 GB and said OK.
I think that covers it all.
Anymore ideas on what to try?
If it is hardware, what could it be?

I'm guessing you did let it do the bootloaders on the flash? Other than that it sounds like a serious hardware issue like a failing processor.

Here are the steps I would try to bring the phone back to a working stock GB. I can only offer a Heimdall approach.
1. Take out your microSD card.
2. Boot into DL mode.
3. Flash this in heimdall: http://forum.xda-developers.com/showpost.php?p=23118162&postcount=3
4. Boot into recovery.
5. In cwm: factory reset. Wipe cache. Advance: wipe dalvik. In Mount: format -system, data, cache, SDCard.
6. Power off.
7: Heimdall UCLB3. http://forum.xda-developers.com/showthread.php?t=1524081. Read the op. Flash it once to complete. If successful, on the PC screen, click the boot loader flash and wait for the phone to complete booting up. After the phone finishes, go to /Settings/Privacy: factory reset and wipe SDCard again. Put it back into DL mode
8. Flash the UCLB3 Heimdall again, with the BootLoader box checked.
9. Once complete, let the phone boot up and run it as stock without the microSD card.
It should run as stock uclb3 - factory new. Go through the set up - do not accept GOGGLE BACKUP for now.
If the phone process continues to crash, you are sol.
gl..
ps..you can always sell the screen..it's worth at least $75-to another user with a broken screen.

Not sure if this will help figure out anything, but if someone is really good at looking at a logcat file, I am attaching one that I obtained from ADB from when the phone started to boot at the ATT Rethink Possibilities Screen all the way through the constant unending force closes of everything as soon as the OS loads.
Thanks again for anyone willing to look this over.

Just a guess and I may be wrong but I looked briefly through the beginning of your logcat. The stock gb kernel should not be looking for /etc/init.d and there were some items listed for voodoo and lagfix and some mentioning of entropy. Is your OS messing up when you are trying to run Entropy's DD kernel?
If you are running a diagnostic with complete stock to make sure the phone and firmware is using complete stock and rfs file system, these items should not be a part of your logcat...
The only suggestion I have is wipe the sdcard and voodoo folder and try a complete re-partition and boot loader flash.

This actually isn't with stock. This is with the Entropy DD kernel. I followed your earlier thread to go back to complete stock and same error. I needed CWM to do other things, so I installed the Entropy DD, but same errors. I just happened to dump the logcat during that run.
As far as your suggestion, I believe that is what was already happening with your earlier post? As for RFS file system, does your Heimdal One Click do that already? If not, what do I need to do to create that specific FS? I think it might actually be Fat32 and EXT4? Thanks!

Heya,
Did you ever have any luck with this issue? I've a phone with similar issues.
Odin to stock - force closes and/or boot loops
Heimdall to stock - force closes and/or boot loops
Install various roms through CWM - force closes and/or boot loops
(I followed all directions to the letter, multiple times)
the last attempt lead me through a series of odins/heimdalls/roms ... basically following a path to install the latest CM10, during which sometimes a rom would seem to be stable before I moved on to the next and other roms would bootloop / fc right off the bat ..
once on CM10, though, it was stable... I was able to install apps from the market, play with settings, etc .... I did experience a 2 or 3 random reboots though in the process and ultimately, when I put my sim card and sdcard in, it was stuck in a boot loop
It doesn't appear that I'm experiencing a power button failure like other people are having ... only reason I mentioned it is because of the random reboots

Infinite Boot Loop

I use stock version of latest android , not rooted , no recovery installed , basically its not modified in any way.
After updating a few of my app's , i restarted my phone and since then its been stuck on those four circles .
I went into recovery mode and restarted my bootloader , that didn't work.

So no backup of your data?
First off, reboot into your bootloader then select Recovery. Use the Wipe cache partition option and try again.
If it doesn't solve your issue you will probably have to factory reset (loosing your /sdcard (data/media/0) content).

Yeah as mentioned, wipe cache is about your only option. Nothing you can do to get your data back otherwise.
Moving forward, I have suggestions on how you can back up your data, if you go to the all guides thread in my signature and look for my data thread.
btw, all loops are infinite
