[Q] At least it's not bricked... - Atrix 4G General

I recently switched to my wife's Atrix. It was never rooted or unlocked, and was upgraded to 141. As with all android devices I touch, I just had to root/ unlock it and flash something.
I used 'automatic unlock 4.2' and everything seemed to go fine. Phone booted normally and I ensured I had root. I then decided to flash ICS. ICS will not boot (stuck at 'M' logo). Tried to restore my backup and it gets stuck at the 'rethink possible' screen. Also tried the obvious fixes such as clearing cache and formatting data.
Any suggestions?

Did you flash pudding and unlock the bootloadrr?

Well, it is unlocked. There is a 'pudding.sbf' in the script as well. I am just getting started with the atrix. I come from the samsung and htc world. Last moto phone I had was the cliq.
Is there a zip that I can pull system images from and just fastboot flash myself? Is that the proper procedure to recover from this kind of situation on this phone?
Oh, and it may be nothing.... when I try to flash ics in cwm, it seems to be done way too quick? No errors or anything... so it could just be I'm comparing apples to oranges (previous phones).

Flashing a new ROM only takes about 10 seconds through CWM. You shouldn't get any errors. After flashing any ICS based ROM you should see a random offset last.

Doesn't matter anymore.... looks like I bricked it.
Failed to boot 1.... and noe can't get into fast boot
Trying a second RSd lite flash but I'm not hopeful
I wasn't getting offset message btw for ics roms (can't believe I didn't notice that)

[Q] Emergency. HELP!

I was adding a new custom ROM to my Droid 2 because I wasn't happy with the Epic ROM so I went with the VZW 2.4.5 Clean ROM, I wanted to add the kangerade blue theme to it but accidently installed the wrong version of it over my ROM and now my phone is in a constant boot loop. sometimes it stays at the droid eye for a while and then load into the lock screen but will go right back into the boot sequence.
When it does boot into the lock screen there is not enough time for me to get into the bootstrapper app to boot into recovery mode.
are there any other ways to get into recovery mode? I've searched high and low on this forum and others as well.
I want my droid back =[
Have you tried to pull the battery and then put it back in. Everytime I do that, I end up at recovery thing.
yup, i've pull the battery many times. i've got it into the android recovery screen but when I to the data/cache format it just brings me to the green android starting screen and goes back into the boot loop, what's weird is that the theme is still applied to the phone

Hmmm. Kind of a roundabout process, but did you make a backup. I'd just restore it to a backup and then go from there.
i can't get into the clockwork recovery, just the stock android recovery. are there any backdoors that i could use with adb?
Try taking the battery out during the boot animation a few times, if that doesn't get you to clockwork recovery you've probably lost your recovery. I've noticed that I sometimes (or always?) Lose clockwork when installing a Rom. If that is the case you may have to sbf unless you can get adb to work from the lockscreen.

how would I go about doing an sbf? could you point me in the right direction?
On this forum three posts down is a guide. Follow the guide exactly, except you will have to put your phone in bootloader mode since it will not turn on and stay on. Do do this, hold the up button on the dpad when you turn it on.
It works, i just did it yesterday. First time ive ever had to flash SBF, and i did ALOT of roms and modding on my D1. The bootstrap is nice but not as nice as a full bootloader.

cool. i think i found the guide. it says backup my sd card to my computer..this doesn't delete everything on the sd card does it?
(not a huge concern since having a working phone is better than losing all my stuff on my memory card)
okay. I tried doing what the tutorial said and I got an error on my bootloader that says
"Critical Error: DEA1"
EDIT:
Well it looks like it was just a simple "I need to update my rsd lite program"
I was using the 4.5 and I read that 4.9 was out so I gave updating RSDLITE a shot and boom, the phone is reflashing as we speak
My sd card is intact... untouched from what I can tell. I had no apps2sd though (with 8 gigs on board why would I?)

[Q] Boot loop but can get into recover and flash

OK heres the deal. I have done tons of searching and it looks like I SHOULD be able to get out of this, but I cant figure it out and I may have gone to far(by unrooting with 4.24 and bootloader 2.16).
So long story short, my launch day evo got lost about a month after I got it. Got a replacement from Sprint(or whoever their insurance is), my original Evo got found about a month or so after that. It has not been powered on since then(a year realistically) with no battery or SD card in it. I got bored and decided to power it up and update everything(because I cant do **** with my new Evo3d, yet since im on a Mac and have no access to a PC). Here are where things went bad.
Phone was rooted with the very original Toast method including S-off with the .76 Eng boot loader. I was running some form of CM6 on it when I lost it.
-Went to power it up and it boot looped at the white Evo4g screen.
-Went into bootloader and tried to get into recovery(had Amon RA 1.7 I think). No go.
-Flashed the new TWRP recovery and got into recovery just fine.
-Flashed the CM7.1.0-RC1
-reboot into a boot loop
-battery pull and a reboot and it loaded, but after about 30 seconds, reboot into a boot loop.
-Thought maybe TWRP didnt like the phone so I flashed Amon RA 2.3
-went into recovery just fine. Did complete wipes of everything using Calkulin Wipe all.zip
-re-flashed CM7.1.0 RC1
-boot loop
-flashed latest radios
-rebooted back into recovery
-reflashed cm7.1.0 rc1
-boot loop
During all of the reboots I would occasionally get the CM7 splash screen and then a reboot into boot loops. I THINK everything was flashing ok.
At this point I was frustrated and was thinking it was something I was doing that was jacked up so I decided to unroot and I flashed the newest RUU(which obviously removes root, S-off, .76 boot loader, etc...) so I did it. Figured I was just trying to get the phone running to sell anyway. Flashed was successful, chose to reboot and guess what. Boot loop. I pulled the battery out for about 10 minutes and it boots into the rom, runs for about 10-15 seconds in the rom and then reboots, back into the rom at least, but only about 10-15 seconds later, another reboot.
Every thread I read on these infinite boot loops were guys saying they couldnt even get into recovery or flash anything, which I had no problem doing(obviously cant really do that anymore with losing root and s-off). So I am stuck.
So current state of the phone is boot loader 2.16 S-on with 4.24.651.1 with all current radios, etc... flashed(as far as I can tell) from the RUU posted on Goo-inside.me.
Does anybody have any ideas for me to try? It seems like I am so close to getting it running because it will run for about 60 seconds but then reboot. I am guessing a hardware issue, but I honestly at this point have no clue.
Sounds like a hardware issue to me.

Thats what I am leaning towards, but why, if a hardware issue, will the phone run in the boot loader or recovery for basically forever without rebooting? It will also successfully(or did) flash everything I asked it to. I would think it would always reboot around that 60 second time frame if it was a hardware issue.
damn, too bad you ran RUU & lost s-off. now you couldn't do anything to test/troubleshoot even if you wanted to.

because in the boot loader and recovery menu I'm sure the phone is not accessing radios, audio components, gps, and all manner of other hardware components that get activated once the phone tries to boot up for real.
It sounds like according to this thread: http://forum.xda-developers.com/showthread.php?t=805612&page=4
That my NV is FUBAR, but since I ran RUU and lost S-off, I cant do the fix. Oh well, I am sure eventually somebody will crack the boot loader and then I can fix it. Otherwise I have to send it off to HTC and I am sure pay them to fix it.
Just to clarify. The thread you linked to is for people who wrote nv items to their device.
What I'm afraid you are experiencing is the bootloop commonly complained about by those running CM roms.
I have yet to find a solution to the CM bootloop and all signs point to hardware failure.

Update gone wrong! NEED HELP!!!

So I've been running MIUI 1.8.whatever for a few weeks and finally realized there hadn't been an update in a while. After discovering MIUI move into the 1.9.Xs I downloaded 1.9.16 and proceeded to update via CWM. While updating it told me 1.9.16 runs off the Gingerbread kernel. At that point I got worried since I had been running the Froyo kernel since I rooted my DX.
After the update I told it to reboot and now it gets stuck at the white M logo. I can boot into regular recovery but I CANNOT get my phone to boot into CWM recovery so I can run the backup!
I've tried every button combination with no luck. i've booted into regular recovery and selected reboot having read that it will boot back into CWM recovery. Needless to say that didn't work either. And lastly I tried running RSDLite to SBF the phone to .602 but since the phone can't fully boot up RSDLite doesn't see the phone.
That is where I am at and I seek the help and guidance of you much smarter folks to help me get my phone at minimum to CWM recovery.
PLEASE HELP!!!
Boot the phone into bootloader mode, then SBF.

I got it into bootloader mode now, but my computer isn't finding the OMAP drivers and the installation keeps failing. How can I get these drivers onto my computer? RSD isn't seeing the phone even in bootloader so these drivers seem to be the key.
You can find the drivers in this thread:

I got RSDLite to see the phone. Now when I try to flash it, it makes it all the way to checking the checksums (which all pass) then tries to switch the phone to BP passthrough. It keeps failing to switch the phone to BP passthrough and now my phone will only boot to the Bootloader screen and says Code Corrupt. It'll let me run the flash again but RSDLite keeps failing at that BP passthrough switch.
Thats where i'm at now.
Try a different SBF file. I had problems like this when i tried to SBF once, but once I found the SBF file that works for me, its always worked since. (I've had to SBF like 6 times now haha)
will find an older sbf file and try that. Wil let you know.
Alright we've made progress! I was able to finally get the phone SBF'd to .602. Then I rocked the Pete's Droid Rooting program and all seemed to have gone smoothly... Except I cannot boot into CWM recovery at all! I've ensured ROM Manager has the correct flash for CWM installed, but when I click Reboot into CWM Recovery, it'll reboot normally. So I turned the phone off and held the Home + Power button to boot into regular recovery. I get the ! logo with the green android, but when I hit hte Search button nothing happens.
So now I'm rooted, but can't get to CWM Recovery to install ROMS.
What do you guys think?
Yeah, Reboot into Recovery from ROM Manager doesn't work for me usually either...in fact, I had to go into the Bootstrapper app, install the recovery again, and then hit Reboot Recovery. This is on Apex though, but can't hurt to try it.
Yea I finally got it figured out. Its been so long since I originally rooted my phone I forgot all about D2Bootstrapper. And I didn't read the how-to guide for updating to MIUI 1.9.16 so that was all on me.

[Q] Defy bricked - any hope?

Hi guys
Before I explain I'd like to say that yes, I have read other threads on similar topics, although none seem to have the same symptoms as me...
This week I bought a software-bricked Defy on eBay with the hopes of fixing it and giving it to a friend. I first tried flashing an old Eclair SBF to no avail (only switched on to bootloader) and thought that it could be failing due to it being on a newer firmware. So then I tried Froyo, and when that didn't work either (bootloops like when I received the phone) I thought my last resort was a CG 5 SBF, so I went for the JORDN_U3_97.21.51 build. This seems to get further into the booting process, with the MotoBLUR animation appearing but I get a BP Panic - 0x00080010 above the animation before the phone switches off. Thinking I had nothing to lose I tried a Gingerbread ROM, but that just bootlooped too so I went back to 97.21.51. I realise I've probably painted myself into a corner by flashing these
I'm all out of ideas with how to get the phone any further and have searched for the BP panic to no avail. I can get into stock recovery and bootloader, although the recovery seems to have issues with accessing the cache sometimes.
Thanks for reading
The same panic have y for the last 2 weeks, after flashing hangs in bootloader (red logo and no animation), after other flash hangs on a animated red logo and thats where you must give it time 3 or 4 min. wating, when its dont works you can try to pul out battery and do it in again while you hold the start and vol. down button, then in recovery menu wipe Dalvik cache and wipe cahe. Maby it works then, when not you can try like me to go again tho recovery and there restore stockrom, thats the way ym getting my defy work again. There are many ways to get it back to work again and it cost me 2 weeks after flashing maby 15 diverend roms to get it works and even than when it works, 2 days work whit rooting it and get 3G alive. So when you think its dead, maby RSDlite can bring it back to live, just like here.
Now my Defy MB525 working like a Defy 526 on Gingerbread.
So don't give up, when you can see whit RSDlite the phoon, it must be possible to get it work, only problem here was on a moment when the battery was empty, but here on XDA you can find the megayver method (charging on a ohter cell like a duo) or what y have don, get my old nokia loader (5V) and whit 2 wires hangs on the battery power it up to 4.1 V, succes.
Thanks, although I was just getting repeated boot loops rather than it hanging on the logo... And that wasn't animated either. How did you manage to restore the stock ROM through the recovery? Did you have a flashable zip? Please bear in mind that I did not get a custom recovery installed
I'll look out for the low battery problem. Thanks for your advice

Thanks, although I'm pretty sure I did wipe cache and data... and I definitely did (several times ) after flashing Gingerbread. I feel like whatever is preventing Froyo and Gingerbread from booting is the same thing as what is giving me the BP panic on the CG 5 Eclair ROM.
I would suspect a hardware issue here.w

I think it might be too It's a shame because I can enter recovery and bootloader okay, and the seller said it broke during a failed software update so I thought it would be a simple matter of reflashing an SBF.
what is bp panic?
what happens when it is booting?
Sent from my MB525 using xda premium
When I try to boot the CG 5 Eclair I get past the static Motorola logo (hence further than any other build) but the MotoBLUR animation is stuttery, with a BP panic at the top (see picture). This goes on for quite a while, then the phone switches off and this loops.
Ok if occurred during a software update, find out which he was installing and try that one. May also be worth trying motoupdate.
Sent from my MB525 using Tapatalk
I might try that, but won't it be useless now that I've flashed CG 5? I'll look into MotoUpdate
Is the general consensus that this is an unfixable hardware issue, then?
Apolgoies if you've already tried this, but I had a Defy which would do the same, either stuck on M logo or error in bootloader.
Each time I just plugged it into PC / USB at bootloader screen, and used RSD Lite to try another ROM. Eventually I found one which worked. I think I tried 5 before finding one which didn't cause any problems.
My defy was a ME525+ and the ROM which finally worked was "DEFYPLUS_U3_4.5.1-134_DFP-132_BLUR"
So, if you haven't already, I'd just suggest try a few more ROMS, flashed from Bootloader / RSD Lite.
Hope it helps somehow

[Q] Black screen/bootlooped Defy MB525

TLDR: See this post for the solution; but do read through the thread, lots of good info!
I've got a MB525 for parts, seller got rid of it because it won't boot up anymore. I've tried it and it shows black screen but it can be seen over USB and I can flash .sbf files. Now, I'm curious whether it can be made to work after all.
First I've tried most of the smgver=4 stock .sbf files but no luck, still got black screen. From what I've read, black screen means the efuse has blown to a higher version. So I tried the JORDN_U3_97.21.51 (smgver=5). Still nothing.
The only thing left would be to flash a Defy+ .sbf, I've seen people recommend DFP-231 Taiwan retail or similar, hopefully a smgver=6 or 7 would work.
I've no idea what the seller did to the poor thing, nor what ROM it came with originally or from where.
Am I right that I should try a Defy+ .sbf? On the one hand, no risk really, I got it for pennies so no big loss. On the other, it just irks me that a potentially fully working Defy should just be abandoned for scrap.
You can try it. But if your defy is green lens the camera won't work on stock Rom only on custom Rom CM10.....CM11.
Sent from my MB526 using Tapatalk
I intend to install a custom ROM anyway. The stock ROM is just to get me going, since right now flashing a .sbf is all I can do. Later on after I gain access to a working system I will install a CM version via recovery. Does that sound ok?

Try DFP-231. If it works, you can go ahead with custom ROMs.
I've successfuly flashed DFP-231. By "successfuly" I mean it now shows the Moto logo and I can enter bootloader (version 10.00, FWIW) and the stock recovery.
But it won't go past the Moto logo, shows it for about 10 seconds and then it reboots, forever. I pulled the battery after ~10 reboots in a row.
Yes, I did a factory reset from recovery (ie. cache and data wipe).
Any idea what might be causing this or what else I can try?
Try to reflash sbf.
And say "bye" to your battery charging via phone.
I've been trying all kinds of DFP-231 .sbf images. So far no luck, still got a few to go. Some of them have a longer delay, such as the first Moto logo staying on for more than 10 seconds – some for 20-30 seconds... but eventually they all bootloop.
I have another Defy+ so I can charge the battery through that one, but why do you say I can't charge through this one anymore?
PS: I've just realized that the stock recovery can flash stuff from the SD card. Would it be ok if I take a nandroid backup and slap it in there? Does it matter from what kind of system the backup is from eg. stock, a CM version etc? Or will anything work?
For battery you can check lasts posts of my problem here http://forum.xda-developers.com/showthread.php?t=2568049... I have never solve it .
Try ti omap blank flash option in rsdlite
Stock recovery cannot help unless you can brute force or steal Motorola's private key
You could try making a custom sbf, which would include custom recovery, from where it could work out.
@sterver1 the battery issue is an exception, it does not occur for most

Oh, so ok. I'm only unlucky...
Good luck...
Still no go unfortunately.
I tried DFP-231, including with TI OMAP blank flash option. If TI blank flash didn't work, am I looking at a hardware problem?
To recap: it's a MB525 (unknown whether red or green) stuck in bootloop: will show Motorola logo for ~10 seconds then restart and repeat forever. I can enter bootloader and flash SBFs but so far none of them helped. I can enter stock recovery and wipe /data and /cache, still no help from there. It was already at BL7 when I got it (tried lower versions first and got blank screen, only BL7 will allow it to boot).
Cannot flash ZIPs from stock recovery because it will only accept ZIPs signed with Motorola's private key which I obviously don't have.
I've read that the wrong region SBF might be the bootloop cause so I will still try out the rest of the official BL7 SBFs, just in case.
The only thing left I can think of is to somehow put custom recovery in there so I can try flashing a custom ROM.
But how do I build a custom SBF with 2ndinit and CWM or TWRP? I have the unpacker and I know how to unpack and repack a SBF. I also know that CG39 is an ext3 image of the /system partition, but that's about it. Which CG files do I have to modify and how?
I'm also not clear on what a "fixed SBF" is. I've noticed that it usually contains only certain CG files, but not sure how it works together with other types of flash and what good are they.
You can flash one of the cm 10 sbfs in the dev forum. Basically you need the sbf to contain the boot menu and recovery to try flashing from custom recovery. A fixed sbf is used to prevent bl version from incrementing by removing the higher version files
Sent from my MB526 using Tapatalk 4
I did it! The SBFs that did the trick are the ones in the OP in the thread Motorola defy bl7 sbf all in one. First the Asian Retail BL7, then wipe from stock recovery, then the MIUI SBF (which also contains CWM custom recovery). Then it booted right up.
I'll be back with more info about this Defy just returned to the land of the living after I poke around a bit (the MIUI ROM is in Chinese, gotta figure out how/if I can switch to English...)
So! Once again it's been proven that it's nearly impossible to softbrick a Defy. Given enough obstinacy ^_^ you can find a SBF that will put it right again.
PS: I should probably also add to the wiki page various stuff I've learned while doing this. I've had a hard time looking up some info, maybe it will help others.
Aaaand I spoke too soon. It booted MIUI successfuly exactly once (1 time). Now after the Moto logo dissapears I get a blank screen (but lit, not off) and nothing happens. I also tried a CyanogenMod ROM (Quarkx), both 10.0 and 10.2 – the CM spinning logo appears, it goes on for a while, sometimes it attempts to boot (got to the Dalvik generation, for example) but then it reboots, other times it will keep spinning and nothing happens.
On the bright side, I now have access to the advanced bootloader and custom recovery with all the goodies (ADB shell etc.) which opens up possibilities. If anybody has any ideas what I could try to diagnose this, please speak up – like I said, I can now have access to the actual Linux system on the phone.
The only idea that pops to mind right now is the CPU settings. Maybe it got overclocked by the original owner and something got fried? Resetting them to defaults didn't seem to do anything.
Still no luck. The MIUI I linked above is the only one that boots up, but won't recognize the SIM card and claims there's no GSM connectivity.
I'm speculating that perhaps something is messed up with the radio hardware, and that MIUI is the only ROM that somehow works around that and boots up, but the other ROMs don't expect it and reboot halfway through the bootup sequence.
I'll see if there's any logs made during bootup.
The reboots are characteristic of bad eMMC(data not getting wiped properly). Does miui work fine apart from radio? Also 2ndboot builds require a specific stock kernel(from eu dfp 231) so try that as well. Try full wipes from cwm, and make sure the data partition is formatted correctly from boot menu(ext3 for ics and below, ext4 for jb+).
The miui sbf masked the data problem(atleast temporarily) allowing the phone to boot up. Unfortunately if you do have other /data issues(which are seemingly unrelated), they all point at bad eMMC, necessitating replacement of the motherboard as the only viable option.
Sent from my MB526 using Tapatalk 4
@thekguy: Yes, apart from the GSM MIUI seems to be working fine, including WiFi. But only one time, if I reboot it doesn't start up again. Sometimes I get a hanged boot logo, sometimes I get endless bootloops. Other ROMs never work, it's straight to hanged or bootloop.
Are you saying that the internal memory has gone bad, like an HDD getting bad blocks? If that's the case, I can probably use a recovery update script to repartition the memory and work around the bad zone(s). As long as I can figure out which exactly are the bad zones (other than trial and error).
Or are you saying it's simply not getting scrubbed properly and it's a problem with the filesystem? In which case I can reformat at least some of them (/system, /data/ and /cache).
But doesn't the flash tool overwrite the partitions by raw-dumping images on them? So how can a bad filesystem survive SBF flashing?
And what about update zips? Do they reformat/raw-dump partitions – or do they just take the filesystem for granted and copy to it?
The image files within the sbf govern raw dumping of partitions. Flashing zip files does not involve wiping partitions in normal scenarios; it can be done thru the update script. As you yourself state correctly, flashing an sbf rules out filesystem errors; provided a data wipe from the stock recovery is carried out for confirmation.
I suspect bad eMMC blocks to be the root cause of your problem; however our partition table is signature verified at boot, and cannot be tampered with. It is possible to emulate a partition table via our custom kernel, but this zone of development has not been entered so far.
A log obtained via adb should be able to verify the same

If the bad eMMC blocks are entirely within the ext3/4 partitions, we should be able to run badblocks on them (taking care not to overwrite the signature at the end of /dev/block/mmcblk1p21 but past the actual file system) and avoid them. As the badblock list is stored in the file system rather than the partition table, I believe that would work.
I've also been experimenting with using an SD card partition for /system and keeping only a few minimal files on the eMMC (I think we could get away with busybox and a modified logwrapper script)—no unexpected problems. It's quite likely those two files won't interfere with the bad blocks, and after they've booted the kernel we wouldn't be touching the eMMC at all (assuming /data and /cache are also SD partitions, but that should be doable). I have been using Quarx's CM11, and I don't think my trick works with stock ROMs (at least I've never had success booting a stock kernel with 2nd-boot), so it might not be a helpful suggestion.
2nd system/ multiboot is a good idea to get past the bad blocks (probably some performance hit though) but better than a non functional phone. 2nd system should work even with a stock ROM as secondary system, not sure why it isn't working for you. I have no idea about the badblock remapping logic
