[Q] Can you flash stock bootloader on custom ROM? - Atrix 4G Q&A, Help & Troubleshooting

Hi. I was wondering if it would be possible to flash the stock bootloader via RSDLite on top of a custom ROM?
Thanks.
Edit: JUST the bootloader. Keeping everything else intact.
I was thinking of taking the stock 4.5.141 sbf and with portable sbf tool removing all the rows, keeping the ones that correspond with the ones in the pudding sbf. What do you think?

UPDATE:
Ok. So I managed to extract the stock BL. It flashed OK, but I got Failed to boot 2 with CM7.2. Flashed pudding back, and it was fine. Guess custom ROMs need Unlocked BL to boot.

[Q] Re-Locking my bootloader

I am wanting to relock my bootloader. I have unlocked bootloader with CWM alien rom. I am returning my phone thus the need for relocking. Or is there a rom I can flash that will not have unlocked on motorola screen while it is booting.
In the same place you found the unlock .sbf, you can find a file called "nopuddingforu.rar." This is the bootloader locker, follow the instructions EXACTLY on that page as to locking the phone again. Also, you can flash the MR5 .sbf if you want 100% stock. Be sure to do a factory reset before flashing back to stock.

That should fix your problem. Forgive me if I'm wrong, but when you flash things with RSDLite you are flashing an actual partition image. The phone internal memory is broken up into multiple partitions, such as /system, /data, etc. When you flash the full MR5.sbf file, I believe it actually flashes all the partitions in the phone with the stock images.
Where is the full MD5 .sbf file located? I didnt see it in the pudding thread....
sorry MR5.sbf
Now that I realize it, I was actually seeing the full MR5.sbf WITH unlock... I can't seem to find one that is locked. Here is the one to the unlock though: http://mophoforum.com/the2dcour/pudding_stock.rar I imagine you could flash that and then flash the nopudding4u to relock it.
EDIT
Here is the nopudding4u file: http://diamantephoto.com/photon_nopudding4u.rar
It consists of only the locked bootloader. So flashing the full MR5.sbf (unlocked) will return your phone back to stock but with an unlocked bootloader. After you have flashed the full MR5, flash the nopudding4u file I linked so that it relocks the bootloader.
It's here in the developer forum. Look for the post from 8/11 about the "Final" sbf. Can't miss it. Good luck!

Yea, this should not be told to people, because as far as I know you HAVE to have the original recovery and as far as I know we have no zip or img file of it currently. So telling people to flash this will only cause problems.

Also, if you flash the full MR5 you do not need to flash the nopudding4u file because you just flashed the complete MR5 file. Meaning you just flashed the whole img file of the phone, meaning that the original recovery is there and it already relocked your phone. The nopudding4u was suppose to just make it so you don't have to flash the MR5, just the small file, so it doesn't take much time. But it wasn't really made clear that you need to have the original recovery, or how to get said recovery.

[Q] SOLVED - CWM won't boot into recovery

Need some help please.
I have Telstra Atrix with ota gingerbread, unlocked BL, rooted.
I can't get it to boot into cwm recovery.
I installed ROM Manager from market, flashed CWM 2.0.2.0 , selected Reboot into Recovery but it only gets to the triangle. From there I can hold down Vol Up+VolDown and get to Basic Android recovery.
I have deleted the racing car app as suggested in one thread to make room, but no help.
If I power off and boot it from Power+Vol Down it comes up "Failed to boot 2"
Can't find a solution in XDA or Google. Any help appreciated.
See if you can fastboot flash a recovery image
sent from my Atrix via XDA premium
Most likely need to delete "install-recovery.sh" @ /system/etc, if it's there, then try re-installing CWM Recovery, and see if that works.
Thanks fellas.
Turns out I had lost my unlock BL by flashing the Telstra Froyo sbf from the xda Atrix Firmwares Superthread.
Reflashed the pudding and it's unlocked again. Actually romracer explained it better in his thread. I thought you couldn't relock bootloader. CWM recovery works now.

U can't actually relock the boot loader, it "Burns a fuse" inside the unit when u unlock. But flashing an .sbf makes it appear as if it's locked again.

Yeah thanks. Romracer explained it to me. It doesn't seem to be common knowledge at all. So people flashing sbf's of stock roms are effectively losing root. I spent hours trying to figure it out and get info searching and asking questions. Anyway, all good now and I appreciate the assistance.
On another point do you know how I can get the Telstra radio so I can use it with custom roms? My phone use is way better since installing Telstra stock Gingerbread ota. If I flash another rom I'll lose it won't I? It is N_01.100.00R
Edit: thanks to @Msd24200 and @marko! for pointing out that Radio remains unchanged when flashing cm7. Also discovered where to get the zip of this radio if I lose it http://forum.xda-developers.com/showpost.php?p=15787709&postcount=1

[Q] Atrix 4g At&t bl unlocked, flash 4.5.91 SBF question

Hello to all
I receive an atrix 4g locked to at&t usa. I unlocked with a code, after i unlock the BL.
I install cwm and romracer and flash CM7(2.3.6) rom from sd.
After i flash Darkside(2.3.5) rom. Now i want to return back to stock.
I have some small problems, the soft keys light is very dimm and the wifi signal is very low compared with my previous iphone 4.
The question is: is it safe to flash 4.5.91(2.3.4) stock sbf with rsd?
I know that the other option are fruitcakes but i just want to know if i can flash this vers with rsd.
System version: 4.5.133.mb860.att.en.us
Android version 2.3.5
Baseband: N_01.77.30P
I read many threads about but i'm still in the "fog". I know that the answer is somewere on the forum and sorry for opening another thread.
Thanks a lot for understanding.
While it's not recommended to use RSDlite after unlocking the bootloader, it will work as long as you only use the 4.5.91 GB2.3.4 SBF (signed). I have done it twice but at my own risk of course.
If you need to return to stock you can flash the fruitcakes, which are stock files. This method is definitely recommended over sbf.

Will flashing the SBF via RSD re-lock the bootloader? I need to take my phone in for a warranty swap (hardware issue) and don't want them to know I unlocked the phone.
It will hide the "unlocked" text during boot but it does not actually re-lock the bootloader. But when you think about it, even though they never intended for the end user to unlock the phone (hence the encrypted/locked bootloader), they still put the warning in if/when anyone unlocked the bootloader. It's there for a reason but I doubt they will find out.

So yeah I was impatient and tried to flash it without waiting for a reply. It kept failing and then all I would get on my phone was "Failed to boot 4 Starting RSD Protocol".
I ended up having to re-flash pudding, which was an adventure in itself (upgrading RSD, rebooting computer, trying different USB ports & cables before it would finally take). I think I will just take it in tomorrow even with it saying "Unlocked" and see if they will swap it out. I'm having touch screen issues with intermittent dead spots and ghost touches.
Did you try the stock SBF with the same combination of port and cable as you did when you successfully flashed pudding? I've heard those two factors can cause a bad flash in the past. I've read that a back port on the computer is recommended for sufficient power and using the actual OEM cable the phone came with is highly recommended as well.
Oh well, hope you get it swapped out, the people at the AT&T stores (if that's where you got it) usually don't pay no mind to that anyways.

Hi,
I do have the same kind of query. I have AT&T Motorola Atrix 4G. I unlocked SIM, unlocked BL, rooted and installed CWM recovery, De-dexed and Webtop over HDMI hacked. I am still on AT&T Stock ROM 2.3.4 / Build # 4.5.91
I am facing random reboot problem while using 3G data service. I want to re-flash Stock 2.3.4 ROM. As per your reply in this thread I can only do this by flashing Fruitcakes as I have unlocked BL ... right? But in this link I am bit confused which file to download and flash amongst 2.3.4 / 2.3.5 att 4.5.133 / ATT 4.5.140 - 2.3.6? Also, after flashing a fruitcake can I still flash a custom ROM later on and at any point of time revert back to stock?
Thanks so much.

If you want to go back to stock, as in the last "Official" build released by Motorola, then you want the 2.3.4 build. And as long as you use the fruitcakes you can go back to a custom rom at any time.

Thanks for your early reply ... Just one thing more I wanna ask that if I flash ATT 4.5.140 - 2.3.6 fruitcake, then can I flash ATT 2.3.4 - 4.5.91 over it? Is the brick warning for going back to stock ATT ROM only after having BL unlocked?
Thanks for your help

Yes, you can flash 2.3.4 fruitcake over a 2.3.6 fruitcake. Just make sure to do the "wipes" (clear data/cache/factory reset/fastboot wipe/etc).
As far as I understand, the fruitcakes will not brick your device, as long as you follow the directions. The risk for bricking applies to using an SBF file and RSDlite.

[Q] Convert a .zip radio to SBF?

Hi guys,
I have some radios for the Atrix from this site: http://forum.cyanogenmod.com/topic/41765-radio-updates-zips-inside/
They are in .zip format.
However, I want to be able to flash them using RSDLite (so I do not need to install fastboot, root, or unlock my bootloader).
Is there any way for me to get the corresponding sbf files?
Thanks in advance!
Anyone? If there is no way to convert or no .sbf files, is there a way to install the .zip radio without rooting or unlocking the bootloader (preferably via RSDLite)?
PS: RSDLite says that the AT&T /zip radios "don't contain any supported file" when I try to select them directly.
it wood be easer to unlock root and add custom rom (total time 10 min

Might just want to look for the sbfs.

Thanks for the replies.
If converting is not possible, does anybody know where I can get the SBF then? I just want to update my guide on fixing permanently locked Atrix phones by adding the final step of flashing back the AT&T radio.
The guide so far did not require rooting or unlocking the bootloader, so I wanted to keep it as easy as possible.
Anyone?
i'm currently on 4.5.91 then i go to this web http://www.motorola.com/Support/US-EN/Atrix Upgrade/Atrix-Gingerbread-Update
then after update process i get 4.5.141 plus having my radio updated to stock rom version also...
btw thanks amilkh for your guide

Question about restoring to stock rom

Ok so i want to restore my atrix 4g, taking my moms upgrade and giving my atrix to her.
Currently it is rooted and the bootloader is unlocked, and i'm using cyanogen 7. I did not make a backup of my stock rom.
Is it possible to unroot, re-lock the bootloader and return to stock rom so that the warrenty "appears" to be un-voided?
I've always found android hacking pretty confusing so could someone point me in the right direction?
Which android version and build were you on when you unlocked your phone? I am guessing either ATT 2.3.6 or 2.3.4? Which build? 141, 91, etc.
I am asking because I was on ATT 2.3.6 build that ends on 141 before I unlocked and I was able to go back to factory stock by flashing the same sbf file through rsd lite. Only problem I encountered was the disappearing status bar which is fixed by totally wiping all data and signing up for a new Motoblur account.

Search for the "fruitcakes" thread over in the Dev section and flash whichever one you want. Fruitcakes allow you to flash back to stock firmware.
The bootloader will still be unlocked. Once you unlock, there's no going back, however its been reported that the word "unlock" doesn't show up when you boot the phone after you flash a fruitcake...

No need to flash a fruitcake if you want real stock ROM. Fruitcake will still show unlocked text on boot screen.
