Phone hangs on Dual core logo, need help

I had CM7 installed on my phone, and then i proceeded to update to the beta 2. I downloaded the file, then unpacked it on my phone sdcard then proceeded to reboot in recovery mode and cleared cache , dalvik, factory settings and then updated the zip file. then clear everything again and reboot. Get stuck on dual core logo.
I can still access recovery and mount usb to add files. can anyone tell me how to fix this?

did you make a backup before installing the beta?

It seems like you've never installed a ROM before, so I would advise you to read before you try again.
Try and restore it from the 1.8.3 SBF or restore from the CM7 pre-beta2.zip.
Don't unpack the zip file.
Oh and I feel obligated to ask, but did you install romracer's recovery?

I have Tenfar's recovery. Does it matter?
When you say restore, do you mean going in recovery mode and then apply the beta-update2.zip?
I also beleive my recovery got updated to Clockwork's when I had CM7 beta installed?
I have read another post on here that suggest I should RSD flash the 1.8.3 SDF and just start anew.
Should I do that? I was on 1.8.3 prior to installing CM7 beta

I understand I probably come across as a complete noob, but I did read before I did anything.
And now this happened and I just need help fixing it, you can just say. Yes flash back to 1.8.3 with RSD, I don't need a dot point instruction on how to do that.
Now my recovery is "ClockworkMod Recovery v4.0.1.4" even tough i originally flashed Tenfar's
and my phone is unlocked.
I have tried many times to clear all caches and update the beta zip again and it does not work, I just get stuck on dual core logo again.
Thanks in advance for any help.

Redownload beta 2 again (I've had problems related to bum d/l's). Install romracers recovery. Wipe. Reinstall.
If that fails use fastboot -w to wipe and reinstall.

Legend, thanks a lot now I can go back to sleep.
I installed romancer's recovery (unlike tenfar's it took like 5 times longer to clear cache and install the rom) but it did work.
thanks for taking the time man.

I think that you forgot to wipe cache and Dalvik cache from within CWM.
For me that did the trick ...

No I had wiped dalvik and cache prior and after update.
Either beta 2 doesn't like tenfars recovery or it was an issue with the download . Since I installed romancers recovery before I tried the new download we will never know

Why use tenfar's recovery when you can use CWM real recovery now.
That might help a lot...

im having the same problem but i used romracers recovery in the first place. ive tried everything and i tried to restore my alien backup but the recovery cant find it... did prebeta1 change the directory? im lost.

Fastboot -w.

Solved:I guess I'm stuck in boot loop....now what?

Ok guys..... newbie here .... literally I'm new to Boot unlocking, root, Flashing etc.
Anyway I have followed this forum for so long that I decided to take plunge yesterday and get my hands dirty.
Here is what I did:
Unlock bootloader, root and install recovery on my Atrix 4G. Atrix was @ 2.3.4 and 4.5.91 during unlocking & root.
Rebooted the phone and everything seems to be in place. Atrix loaded like the way I bought it 7 months back. No problem until now.
Also created a restore folder on my external SD. Worked fine and was successful in creating backup with time stamp
Now here are my steps and subsequent issues that I'm facing:
1. Downloaded CM9 zip file from this thread(http://forum.xda-developers.com/showthread.php?t=1500535) along with Gapps to my external SD
2.Entered recovery mode during bootup and tried to flash CM9 and Gapps. Flashing seem to have gone well and completed (note I did not do clear data, clear cache or clear dalvik cache under advanced options being a newbie)
3. Reboot the phone and can only see red Moto logo and unlocked on top. Left for about 5 minutes and nothing happened.
4.Did a battery pull and entered recovery mode. wiped data, cache & cleared dalvik cache
5.Went to Install zip from sdcard option and tried to reflash CM9. Flashing seems to have gone well and completed
6. Reboot phone and again can only see Moto Red logo with unlock on top and nothing more.
7.Battery pull followed by recovery. But This time I tried to restore from my external SD. also wiped data, cache & dalvik cache
8.Restore took about 3 minutes and completed.
9.Reboot the phone. Now the phone boots and goes to Rethink possible screen and get sstuck.
10. Left it for 1 hr....nothing.
11.tried steps 7-9 again and still stuck in "Rethink possible" screen during boot.
What did I do wrong? Did I soft brick the phone? I can still enter recovery mode and read my internal and external SD and can see all files. i hope I didn't brick my phone doing this. If I did, I would regret!
Here are my options:
1.Try a stable ROM like CM7 and see what happens. I didn't want to do too much damage so haven't tried this option yet.
2.I know there is a way to hide 'unlock' during boot up (if someone can point to it obviously). Hide the 'unlock' and return the phone to ATT and tell them that phone would not boot after 2.3.6 update and get a refurbished one
Please let me know what your thoughts are. I'm currently crapping on my pants
Edit: I just tried Newtrino rom and stuck @ Moto screen which says unlock.
Edit 3/4/2012: Please go to the last post for the solution. Tenfar's CWM is old and cannot deal with latest ROMs. Use ROMRACERS latest CWM or touch based Koush's CWM for future ROM flashing.
Old CWMs will give you sleepless nights!

Ok tried restore again after wiping data, cache & dalvik cache.
Now after reboot, My Moto Logo screen says unlock and just starts flashing.
I can still get into recovery......
can someone please help me......

What you can do is: install a "stable" ROM of Gingerbread:
--Go in recovery, put a .zip of the ROM on your sdcard (with your computer), and after wiping data, install it .zip.
--Or you install a new ROM with fastboot
Anyway, be careful with your battery, because if it is empty, with no ROM on your phone, it'll be crap!

thank you for your response. However I tried that already Nutrino GB ROM. Again, I would go to 'M' screen which says unlocked and its stuck there for ever.
I used tenfar's CWM. Not sure if I need to use any other CWM. Also since my phone doesn't boot, I'm not sure how I can install any other CWM

Don't worry, soft bricks are easy to recover on the Atrix thanks to us being able to access fastboot.
For flashing a new recovery:
While your phone is off, press Volume Up + Power to power up, then release when a menu appears on your screen and navigate with volume down until you see Fastboot, select it with the volume up key.
Get the necessary files for fastboot, place them all in a folder called "moto" in your C: drive, and type in the following in a cmd window (assuming you're using windows and that the recovery image is called recovery.img):
C:/Moto> fastboot flash recovery recovery.img
C:/Moto> fastboot -w
C:/Moto> fastboot reboot
Now access your recovery wipe dalvik cache, cache, factory reset and then flash a new ROM. It SHOULD boot without issues. I personally use Koush's Clockworkmod Touch, also remember that Neutrino tends to get "stuck" sometimes after the first attempt to boot and requires a battery pull and then you try to boot again. (It takes a while)

Many people also seem to have suggested RACEROM CWM. Which one would you suggest? I'm so nervous about all this now. Just have this butterfly in my stomach

flash the latest recovery and wipe everything in recovery and flash neutrino again. It should work after that. try neutrino 2.2 though. 2.5 still has it's kinks.

1st off, relax. It's difficult to brick your phone from this point Just don't get any bright ideas with .sbfs lol.
As others have said, make sure you're on latest recovery.
Question: are you installing from internal or external SD? Internal is recommended for flashing most ROMs.

As someone else said, the ONLY thing you should NEVER do is flash an .sbf or go through an OTA update, that's a surefire way to hard brick your phone. From this point on it's VERY DIFFICULT to completely brick your phone using software only.
RomRacer's CWM is based I think on v5.0.2.7? Koush's latest recovery is v5.8.1.5. I honestly couldn't name any tangible differences other than the touch interface, which is the reason I use it in the first place. (I hate mashing volume keys like a madman) It really doesn't matter which CWM you use, but when I soft bricked my phone I recovered with CWM Touch.
I would recharge your battery to 100% before trying to recover it, as that is one less headache to worry about, but if your phone starts saying 'Battery is too low to flash', do not panic, you only need a USB cable you don't mind sacrificing (doesn't have to be new). I will go into detail in case you actually need to do this.
Just make sure you use the fastboot -w command and wipe EVERYTHING through CWM before trying to flash anything else.

Thanks I was able to fix my boot up issue using ROMRACERS CWM. I didn't use any command prompt or anything. I just downloaded zip file from this thread, entered recovery mode -->Install Zip from SD card --> Chose ROMRACERS zip --> it automatically flashed the recovery and I then rebooted recovery under advanced options.
After that Wiped data,cache & Dalvik Cache and proceeded to install CM9 and it booted up up flawlessly.
I'm kind of surprised that tenfar didn't add a not to use his CWM as the latest ROMs use latest ext format.
That seems to be issue. However, I'm pleased with your guidance and final output. Thanks a lot dude.

[DEV/LEAK] ICS for A501

Got hands on an update for A501, but it's update only not a full package.
If someone is interested to build and then dump the full system (sorry don't have time to do it) :
1. Download this files :
http://cdn.acer.futuredial.com/Acer_A501_4.015.15_4.031.24_COM_GEN1_1315884879002_1b385af8.zip

(You will have to decrypt packge to extract update.zip from them)
2. Wipe all with recovery
3. Install all packages in this order. (don't wipe between installs)
I may be able to provide a full dump this week-end if nobody did it.
Edit : Flashable (full) update : http://forum.xda-developers.com/showpost.php?p=25050248&postcount=38

Thanks Vache!

Thanks, I'll try to take the time to flash all this...

This implies that those of us who are on 4.066.24 need only force up to 4.066.29 and from there to the final version? It also implies that the software is out there for updating to the "real world" instead of just being leaks. Is this your understanding as well?

yeaaaa tnxxxx

Lets hope I get the 4g speeds.

3G works, SMS works.
This build number indicate it's a very early build but it works great, seems on par with the latest A500 leak.
Glad to see that Acer is finally working an our A501 !

installed all 4 OK after reboot it updates EBT and reboots again wiping out boot loader and recovery image.

3g initially did not work. I had to delete and recreate my APN for data to work.

Thanks Vache!
Now, I hope all of you are copying down your UID numbers before running the updates.
Will make things a whole lot easier if you need to roll back

What I also found is that if you try to go into recovery (vol down) it restores you back to Stock 3.2 HC Beware!
Also make sure you make a backup of all your stuff on internal SD card. the process will wipe it!!!!!

Thank you! Good)

There also apears to be something fishy with the update as well with the bootloader.
If you try to flash the custom bootloader with the thor recovery img each time it boots it appears to wipe the recovery image out and it wont go into recovery anymore after the first reboot and has to be flashed again? (shows dead android on its back with door open with red triangle)
http://forum.xda-developers.com/showthread.php?t=1594873
Not sure whats happening there however it does come up in RED after the PASS shows.
Secure Boot: Image LNX checksum fail.
Is there some funnyness locking happening with this update?
What am I doing wrong?
Update: I went back to back up of my prior ROM "DEV][AOSP] ICS sources and build instruction for A501" and it doesn't wipe out the recovery image. Is this because the boot-loader is specific to this ROM as it is for 4.0.4? Any ideas?

You have to root and remove /system/recovery-from-boot.p or it will reflash the recovery at every boot (assuming it's the same as the A500)

Could anybody tell me if my ICS Root tool works with this leak? I don't have access to an A501 and I have no idea what version of the kernel this is running etc.
Thanks!

blackthund3r : ICS ROOT 5.1 works on this version. I chose to run it for the latest A500 leak and everything went just fine.
Mounting /system works too.

I tried wifi no work. Reflashing again :|

WiFi works for me, if you had a custom ROM you may have forgot to wipe something.

1. install stock 3.0.1 rom
2. update to 3.2.1
3. make factory reset
4. go to recovery and flash this
5. wifi power on but no visible all wifi routers....
sometimes there are network. enter the password. all. again does not work.

OK it should work the way you did. One thing you can try is to install CWM, use it to wipe everything (factory, data, dalvik) and install from there. I know it can be done, I tested this.
Hope it will work for you too.

[Q] A500 hangs at booting primary kernel image

My Acer Iconia A500 was frozen, I turned it off by holding the power button, since then, I can not reboot the tab, it hangs at booting primary kernel image.
I have Skrilax_CZ V8 bootloader, CWM recovery 1.7.3, and the Flex-Resurrection_Rev1-Aroma-Public Rom.
-----------------------
I searched here, tried the methods by Moscow Desire
"Boot to recovery, and this time, do all your wipes
Wipes Menu
a. wipe Data/factory reset
b. wipe cache
c. wipe Dalvik
Go to Mounts and storage
a. Format system
b. Format Flexrom
Install rom, and make sure it's a rom with an ICS kernel.
As a last chance if the above normal things don;t work,
you may have corrupted data somewhere, and in this case, go to Backup and Restore and toggle Data Media."
------------------------
And tried method by Skrilax_CZ
"You can also wipe userdata from fastboot: "fastboot erase userdata".
-----------------------
I did it several times, after installed the Flex Rom, ( I also tried the Lightspeed_4.8,) it still stuck on the booting primary kernel image, What should be my next step?
I saw somewhere Dibb_nz mentioned that re-flash the BL, recovery.img, not sure if I should try. I do have the CPUID and SBK numbers.
Thanks for your help, anyone out there.

I'm having the exact same problem. I tried what you did, and it still didn't work. This is my first time flashing, so I'm not sure what to try next. I do have one idea - I thought the ROM did have a kernal, so I didn't flash one. I'm going to search for one and try that.

I switched to Skrilax's V9 bootloader thinking that might help but it didn't. When I do a recovery with the back up of my normal rom I made before flashing then and only then can I get past the bootloader. The backup says there's an error when recovering my data though, so I'm going to have to start over from fresh either way.
Any help would be greatly appreciated. I've been at this for over 7 hours now.

[Q] Can't remove multirom

I have a Nexus 7 WiFi 16GB running stock rooted and 2 custom roms via multiboot.
The custom roms stoped booting and now if you select any rom in multiboot it just boots the stock.
I tried to remove multirom (by reflashing boot.img to the device) and there were no errors but multirom remains.
I then thought I would reflash everything, bootloader, recovery, system the works. All of these processes reported 0 errors but the systems remains exactly the same.
I have also noticed that if I make any changes to the stock rom (install an app or change a setting) when the device restarts it's not there. It's as if the system isn't persistent.
Can anyone help???

Almost sounds like something in the file system got switched to read only.
What are you using to flash the device?
When I was playing with Multirom I think all I had to flash using Wug's was the stock kernel found under advanced options in order to remove multiboot.
The whole thing about making changes to the system that fail to persist is almost like root is borked or the bootloader is locked.
Does anyone know if its even possible to lock the bootloader once rooted?

4. Uninstaller
MultiROM uninstaller: multirom_uninstaller.zip
Flash this ZIP file to remove MultiROM from your device. It will erase all secondary ROMs. If you don't want MultiROM menus in recovery, re-flash clean TWRP, but it is not needed - those menus don't do anything if MultiROM is not installed.

Could've sworn there was an Q&A section

I have tryed flashing from commandline with fastboot as well as using both Wug's and Nexus7 Toolkit. I have tried flashing the stock kernel with Wug's and no change. The bootloader certainly says unlocked.

Apologies, it was late, I was flustrated and I didn't see... if I knew how to move it I would.

I had the same problem trying to remove multirom, it just wouldn't budge!! I found the best way was to just erase everything on the tablet with fastboot commands and then just re-flash a stock image of Jellybean.
There's nothing like dusting off the old cobwebs once in a while to get that out of the box feel again!

Exactly what im trying to do.
I have ran:
fastboot erase system
fastboot erase userdata
fastboot erase cache
all with no errors but nothing was actually erased?!?

Start again but follow it in this order. But you also need to flash a stock ROM too. Your only doing half a job.
fastboot erase cache
