[Q] Atrix 4G (AT&T) boot loop - Atrix 4G General

Hello, I registered and created this thread because I couldn't find anything about my problem.
I looked for hours on this forums and googled a lot but still I can't resolve this.
Well here is the thing... I bought a used atrix 4g (AT&T), it came with 2.3.6 (4.5.141) unrooted
and bootloader locked. After a lot of reading I unlocked the bootloader and did a backup
so I wouldn't have any problem after that if I wanted to return to stock. Then, today I tried to
install CM7 so I did another backup just in case using CWM and installed it like it was
told from here:
wiki.cyanogenmod.com/wiki/Motorola_Atrix_4G:_Full_Update_Guide
*Boot into the ClockworkMod Recovery.
*Once the device boots into the ClockworkMod Recovery, use the side volume buttons to move around, and either the power button or the trackball to select.
*Select the option to Wipe data/factory reset.
*Then select the option to Wipe cache partition.
*Select Install zip from sdcard.
*Select Choose zip from sdcard.
*Select the CyanogenMod update.zip.
*Once the installation has finished, select +++++Go Back+++++ to get back to the main menu, and select the Reboot system now option. The Motorola Atrix 4G should now boot into CyanogenMod.
After the installation finished it rebooted and stayed at the Motorola logo so the first thing I thought was... this might take a while so I'll just wait for it.
After around 15 minutes it was still there so I flashed my backup back because I read that would make my atrix go back to stock like it was before.
After it finished flashing all the stuff back it stayed on the logo screen again
I don't understand why my backup isn't working and also why didn't CM7 worked even if I did everything like it was explained?
I still can't make it boot but I can get into cwm recovery.
What should I do? Also sorry if this was already asked and resolved, it is just that I couldn't find anything like this.

Nevermind, romracer CWM solved this.
Please lock this thread and sorry for bothering you guys. You are the best

Ive rooted my hero, and now Id like to start flashing ROMS, but have no clue how to go about doing this.

The info is around. Just choose which rom you want download it put on the root of sdcard,power of phone, hold home key and hit the power button. That should bring up the recovery menu, you will probably have to wipe then choose flash zip from sdcard.Once that is done reboot phone.enjoy...

Also...Do you have a custom recovery http://forum.xda-developers.com/showpost.php?p=4898505&postcount=1
Yes I flashed the 1.6.2 recovery file and have a nandroid backup.
I booted into the recovery screen, had no option to wipe, just install zip from SDcard, so I did that, it installed, THEN I had an option to wipe, as well as flash zip from SDcard, and first option under wipe was data/factory reset.
And thanks for the LMGTFY, but my specific recovery screen had a different option than what I found on google so I thought Id ask before I bricked my phone.
rebooted, it went into this endless reboot cycle, so I rebooted back into recovery, wiped, reflashed the ROM and rebooted and everything appears to be working now.

Help! Might have messed my phone up

LOL i was about to say i have a fascinate, but it would be redundant because I am posting in a Fascinate forum.
Hi guys, first post, thought I would post first about something not help related, but my phone is messed up.
I rooted my phone with 1 click root from android central, then i flashed it using odin and backed up my rom ( i guess stock touchwiz) with CWM from rom manager. Then i installed this theme: AOSP REVOLUTION a port on androidforums the adress is /fascinate-all-things-root/251094-theme-port-aosp-revolution.html ( after androidforums obviously, i cant post links!) ) -_-
I installed it by downloading the zip, renaming it to update, and launched CWM recovery and ran apply sd update.zip. Then i rebooted my phone the verizon logo flashed for a long time then the screen went black, and when i pressed the power buton all that happened is that the 4 buttons would light up.
Can anybody help me, sorry if i pissed you off because of my uber-noobness, but i just got the phone a month ago and rooted it yesterday. I made sure i followed the direction so my phone does mess up, but something went wrong after installing that theme. Thanks a FREAKING GAGILLION if you can help!
PS Another noob move but how do I run the backup that i made? sorry for my noobness if it offends u.
If you have ClockworkMod recovery installed, you just need to boot into it and restore your backup. Shut down the phone. Hold both volume up and down and then press power. When you see the Samsung logo, release power but keep holding the volume buttons. It'll boot into standard recovery. Select apply update.zip and it'll boot you into Clockwork. Should be easy to figure out how to restore from there.
If this doesn't work, then you don't have clockwork installed, or installed correctly. There should be a recent post on installing a new red clockwork. Follow that and then follow the instructions above except for applying update.zip. The new red clockwork boots directly, without going through the stock blue recovery first.
Alternately, there are various all-in-one Odin packages floating around here that will return you pretty much back to stock.
The problem you have here is that you flashed a theme that is made specifically for a the asop Rom. So the thing to do is download another Rom, place on root of sd card, boot into recovery (hold both volume keys and power until samsung logo flashes twice), wipe your data and cache, flash rom and reboot. I'm assuming you have updated to dl09 so you want a dl09 rom. here is a suggestion http://forum.xda-developers.com/showthread.php?t=894126, just download system rom part, ignore the odin stuff. hope this helps

This was also a mistake. On this device CWM depends on there being a cwm update.zip on the root of you sd card. To flash a rom/kernel/theme on this device you leave it alone and placed anywhere on the card. When booted in to cwm you use the "install zip from sdcard" option.
good day.
Yes LordShark,
As mentioned above, you do not rename the file at all. You can call it "umpty-Squat-Rom-Of-The_gods.zip or whatever you want, you boot into the CWM and as pointed out above, you will choose install zip from card and you will navigate to that umpty-squat that you downloaded to the phone.
So pull your SD card out and download a ROM and place it in the SD Card in a folder you like, I personally just use the default location od SD CARD / CLOCKWORKMOD / DOWNLOAD and store all my ROMs and stuff in that folder.
Hope this helps. Do not get too excited, your not ubber borked.... even if you are in a total panic you can follow the Adrynalyne ODIN back to bone stock DI01 post and in not to long you will up and running.

[Q] Installing CyanogenMod on Nexus S 4G?

I am a total noob and am having trouble installing CyanogenMod onto my Nexus S 4G. I barely rooted the darn thing, and I am using a guide that involves ROM Manager. It says I have to mount the SD card using ROM Manager, but I can't figure out how to. If there is a better way to install CyanogenMod, please tell me, because all the guides I have been finding are way too technical for me to understand, and I have been trying. Any help is appreciated.
Can you tell us which guide you are using and which step you are on? I think you must mean ClockworkMod not ROM Manager.

If you already have clock work then all you have to do is drag and drop cyanogen into the root of your sd card. Then flash through clock work.
ht tp://ww w.redmondpie.com/install-cyanogenmod-7.1-gingerbread-rom-on-nexus-s-4g-how-to-tutorial/
That's the guide I was using, I got stuck on step 4.
Is the rom the .zip file I downloaded from the cyanogen site, or is it inside the folder?
The rom is the zip file. Boot into recovery and select choose zip from sd and navigate to it and install it.make sure to do a back up and wipe cache,dalvic and do a factory rest before flashing the rom

Can you explain this part more? Is this the part of the guide that says "make a nandroid backup"?
1. Mount USB and drag and drop cm7 zip & Google apps into root of SD card.
2. Turn off nexus.
3. Boot into fastboot by holding volume up and then power button.
4. In fastboot go to recovery (power button is used as enter button, volume buttons represent up and down)
5. In recovery go to backup and restore and back up your current rom.
6. Go back and then wipe data factory reset and also wipe cache.
7. Go to advanced -> Wipe delvik cache.
8. Go back and then go to install zip from SD, find cm7 flash it, then flash Google apps. You can flash kernel right now if you want.
Hope this clears anything up

I got to your step 5, but when I choose Recovery, after showing the Google logo it briefly shows a box and an arrow coming out of the box and an Android logo, then the box changes to a triangle with an exclamation mark. It stayed like that so I just rebooted the phone.

That means you don't have Clockwork recovery installed. You need to download the latest Clockwork recovery image and place it in the tools folder of your Android SDK Folder(wherever you placed it). Then press shift and right click on the tools folder and select "open command prompt here". Then boot your phone into bootloader by pressing volume up and power button at the same time. Connect your phone to your computer via usb cable and in the command prompt you opened type: fastboot flash recovery name of recovery image here.img and press enter and you will see in the command prompt window it will say sending image. When it is done scroll down to recovery on your phone using the volume buttons and press power to enter. Your phone will reboot into Clockwork recovery and from there you can continue on the previous posts steps. Hope this helps. You can download the latest Clockwork by going to this thread: http://forum.xda-developers.com/showthread.php?t=1078213 and clicking on the brown "CWM Recovery" under 'How to: Root the Nexus S 4G'.
well I'm pretty sure I do have clockwork because there's a folder on my phone that is called clockworkmod, and I did root the phone successfully at the very least, but I'll try putting a new one there.

Alright here is a little run down on whats going on with your ns4g, you probably already flash clockworkmod on your nexus, but what samsung did was that it will try to revert back to the stock recovery. So what you have to do is flash Clockworkmod again to make it stick. Honestly it is good that it doesn't stick because then it would be easier to unroot the phone.
So now you have 2 different options on how to flash clockworkmod. 1) you can do it through fastboot but you have to have adb set up. I'm not sure what method you used to root your phone so i am just assuming.
2) you can download rom manager and flash clockwork through there. (Honestly i haven't done it through this method so i cant tell you of the pros or cons that are attributed with this).
NOTE: If you dont have super user yet it would be a prime time to flash it once you got CWM going.
For me, I only needed to flash clock work twice through fastboot in order to make it stick.
Good luck.
The guide I originally was using for this had me using rom manager, but it kept telling me I had to mount the SD card even though it was shown up in my computer.
If I were to flash clockwork again with adb setup, how would I do that? Sorry to be so asky, I just want this process to end correctly.
You have to set up adb if you don't have it already, go to ns4g development and go to vandam's thread that has all the list of rom's and rooting guides. Check out wolverines rooting guide, he goes indepth on how to set up adb. It make take awhile to set up but learning how to work in fastboot is essential in rooting the nexus.
Good luck

Well it was confusing and I almost asked for help again, but I finally got it flashed again and now cyanogen is working. I really appreciate the help and for pointing neon the right direction. As a final note, is there anything else I should know, like updating or something, just general knowledge (basically, "now what?")?

Did you get all the Google Apps installed too? That's the only "unusual" aspect of CyanogenMod.
Yep I got the Google apps.
Congrats dude its good you got it all working, BTW when ever you switch roms like from CM7 to miui you always have to wipe data, cache, and delvik cache. Delvik cache is in the advanced tab of CWM. If your just up updating from different versions of the same rom, you just need to wipe cache and delvik cache. That's about it, the hard part is done, enjoy flashing.

Actually if you are updating from different versions of the same rom, you don't need to wipe anything, you just flash it.

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.

[Q] Cannot update to ics after rooting.

I rooted my motorola defy using SuperOneClick. It said rooted successfully and I got a superuser app in my menu too. Now, I downloaded ics 4.0.4 firmware package and latest google apps and unzipped it to my sdcard. When I turned off my phone and then switched it on again by pressing poweron+volumedown key, an android icon with an exclamation mark came denying me root access. Please tell me what to do now.
You got it all wrong .
1) You never unzip the rom or gapps
2) Android exclamation mark isn't denying root access, it's just stock recovery, which you can access be pressing both the volume keys together.(but you don't need to do that)
3)After you root your phone ,install defy 2nd init(you can search it in the forum)
,which will install clockworkmod recovery on your phone.
4)flash the rom and gapps through that recovery(press vol down when led turns blue on restart to access recovery)
you can search for detailed threads in the forum.
Okay, I did what you asked me to, installed 2nd init. Did everything. Place the zip file in sd card. Pressed volum down when led turned blue. Unzipped the ics package. Done.
Now, when I rebooted my phone, I got a blue animation saying cynogenmod 9 and that animation is now going on forever. It is not rebooting my phone.
Put out the battery, put it back, start your phone, ready!!
If not, make a factoryreset in the custom-rom-section under stable or latest and reboot.
Okay. You ARE a noob! Sorry, but this really is funny! The op seriously has NO clue what he is up to! My advice: stay away from custom roms until you know what its all about. READ the guides!
Unzipping the rom and flashing it through stock recovery?? Are you trolling??
sent from my Defy+
Hahaha.
Ok when the light goes blue press vol -
1: Go to custom recovery,
2: Wipe data/cache
3: Go to advance
And wipe delvik and battery stats,
4: install update from sd card pick your rom your flashing,
5: Install update from sdcard again pick the kernal you want to flash ie cm9 kernal
6: install update from sdcard chose your gapps you want and flash it.
Do step 1 2 and 3 again then reboot your phone.
You scroll with volume buttons and pick with power button.
If you get stuck just search.
Hope this helped.

before posting for help, you should read all the posts and get some information about flashing roms..
and, to solve your problem, you should enter to the recovery (volume down on blue led) and wipe data, wipe cache partition and go to advanced -> wipe dalvik cache.. then your phone should start without any problem
