[Droid RAZR M General] kingwaqar:
i dont have money right now :( is there anyway for free?

i am poor :( if there is anyway to unlock bootloader for free please tell thank you brother
[Droid RAZR M General] sd_shadow:
no there is not

if possible downgrade
[Droid RAZR M General] sd_shadow:
cannot downgrade

Is this work on 183.46.15.XT907 rooted ?
[Droid RAZR M General] sd_shadow:

[Droid RAZR M General] nom_an:
Which one is for Downgrage ?
[Droid RAZR M General] motolio:
VRZ_XT907_9.8.1Q-94-1_CFC is 4.1.2 (which Im going to try, in order to attempt to use safestrap... but none of them will downgrade the bootloader).

Does anyone know if safestrap is just kernel dependent?
[Droid RAZR M General] motolio:
So after doing a bunch of file rearranging, My bl now says 10.9b (2013-03-22). But in order to do this, I had to flash it with the system of 4.4.2. So the BL is downgraded, but the "Get started" screen after booting up is completely frozen so I can't enable debugging to root or do motocolyps to unlock. What can I do?
[Droid RAZR M General] sd_shadow:
you cannot downgrade with the bootloader locked
[Droid RAZR M General] DragonFire1024:
I can't find a working link, but may have missed it. I have unlocked bootloader XT907 with KitKat. Trying to install a custom ROM, but appears the only ones I can get are for the JJBL. So how do I downgrade?
[Droid RAZR M General] sd_shadow:
i just use RSD Lite and a Jellybean firmware

Thank you very much [MENTION=4267571]sd_shadow[/MENTION]

I replied to a section of that thread that has the link. Wasn't sure anyone would see this one.

One more thing. What else can RSD Lite be used for? I'm curious as to what other software and what not can be used with it.
[Droid RAZR M General] sd_shadow:
RSD Lite can only be used for Motorola stock.zips

---------- Post added at 05:33 AM ---------- Previous post was at 05:24 AM ----------

Incase RSD Lite fails, which does happen

[Droid RAZR M General] DragonFire1024:
I've only had it fail on me once and that was because a bad cable. But good to know there's another option :)

---------- Post added at 12:50 AM ---------- Previous post was at 12:36 AM ----------

Last question. I already have a custom recovery flashed. When I downgrade do I need to flash it again?
[Droid RAZR M General] sd_shadow:
Yes, if you flash with RSD Lite, you will need to flash a custom recover

There are different recoveries for KitKat and Jellybean
[Droid RAZR M General] DragonFire1024:
RSD failed so I tried the Msfastboot method. I used the 4.1.1 file from your thread. I followed the steps in this link from your thread. Everything flashed perfectly. No errors at all, but when I reboot, it stays on the Motorola bootloader unlocked warning for a few minutes. Then the screen goes black and then back to the warning. So for now I flashed back to 4.4.2...with no issue at all. Phone boots normally :confused::confused:
[Droid RAZR M General] DragonFire1024:
Ok So I went back to the drawing board. From another link in your thread, instead of 4.1.1, I went and tried 4.1.2 (selected DROID RAZR M on the right, selected 4.1.2). Then I went to page 1 of this current thread and followed the instructions. Replaced the XML with the one provided in the OP .zip file. Opened RSD, connected the phone in fastboot, Selected the file, pressed start..............Success :D I am now on 4.1.2 JBBL!

---------- Post added at 04:35 PM ---------- Previous post was at 04:18 PM ----------

I just went here, scrolled to custom recovery, downloaded TWRP 3.0.2-1 file, extracted to a new folder, moved the recovery.img to my ADB folder containing fastboot and powered the phone off. I pressed volume down + volume up + power to get into recovery mode, selected AP fastboot and flashed recovery.img using command: flashboot flash recovery recovery.img. Success so far. Command: fastboot reboot and waited for phone to fully boot then powered it off again. Did the 3 button trick, selected recovery.....Success! :D I am now in custom recovery. I decided to do a cache and dalvik wipe for now and flashed SU. Wifi + data are off. I have not added an account.
[Droid RAZR M General] DragonFire1024:
[MENTION=4267571]sd_shadow[/MENTION] You really are a miracle on here. Pretty much because of ALL the material you've gathered over time, I think I've located every file I need to go to any version of Android from 4.1.1 to 7.0. Once I figured it all out, got all the files, everything was actually very easy. The hard part was tracking down older ROMs like CM 12. Lineage got rid of all the CM ROMs for the XT907 when they took over. It took several hours to locate everything, but I got it :victory: :D

I am currently on Lineage 13 (Android 6.0). The phone is much more stable, a lot faster, the display is clearer and it's just like the real thing. This phone has new life and a longer life span thanks to you and all the developers on XDA. If it weren't for all of you, none of this would be possible for me, or anyone else. Infinite thanks if I could give them to all of you!!! :good:
[Droid RAZR M General] topshot:
Perhaps you could add some links to the files you found.

I've stayed on pretty much stock 4.4.2 (w/ unlocked bootloader) but keep running out of space though I hardly use any apps and other oddities the past few months so I'd like to find a stable, lightweight ROM to try out to keep me from buying another phone since they are all so dang big now (and much more a PITA to unlock).

[MENTION=4267571]sd_shadow[/MENTION] I did actually have one problem. This has 8GB instenal, I know some is devoted to /system. So I got the ROM installed, running etc...But IDK where to post this so here goes: I was installing apps and it said internal storage was full, despite the fact it had said there was 1.6gb used of 4gb...which should be 8? I am confused. Did the ROM do that or TWRP?

EDIT: 4.5 for system and the rest user storage. Apps kept getting installed into the system partition? I couldn't figure out how to change that?

Let's keep the comments on topic with the title of the thread. Questions or troubleshooting for a different issue or anything NOT related to downgrading from KK to JB should be posted in HELP or Q & A threads.\

I know it might sound trivial to some members, but different sections are set up for the sole purpose to make finding information much easier, without having to navigate through a ton of unrelated comments and clutter.

And one other thing i installed TWRP which was in downgrade folder but my mobile was not starting recovery then o triend TWRP which was shared in Lineage OS 7.1.2 CRDroid thread by DiomondJohn, it gave error on flashing, then after some search i used rahimali's TWRP, and it flashed and worked perfectly.

Thankyou everyone for your effort for this old device, when i bought this device it was already on 4.4.2 so after returning to Jelly Bean Battery timing has approved little.

---------- Post added at 09:26 PM ---------- Previous post was at 09:23 PM ----------

I have actually used RSD to flash TWRP and Custom Boot.img, didnt even change anything in xml file, just rename recovery and boot to their default and replace them with stock one.

I think thats the advantage of Unlocked Bootloader.
[Droid RAZR M General] H.Rehman:
I am unable to downgrade from 4.4.2 to JB

I followed you instructions and replaced the file you attached in the downgrade folder.

The failure occurs in Process. 13/20 flash boot "boot.img" -> Phone returned FAIL.

Phone Fast Boot:

You can't downgrade with locked bootloader

I believe you can root with rootking

Or

see hydrogen peroxide root

Only option for bootloader unlock is Sunshine app

If kernel date is July 2014 or after

can only be unlocked with sunshine app

I would root with hydrogen peroxide, even though kingroot or temporary root should work too

Very useful information within this thread.

I'm not sure if any of you three can answer this question, and it might be off-topic but I figure why not.

Where the heck did ##PROGRAM go and if it's just not available then how can i upgrade to KK w/o losing my jellybro baseband settings (3G VZW MVNO programmed)? Is it as easy as not running the pair of fastboot erase commands when flashing the KK files?
[Droid RAZR M General] rickybogo:
I had an unlocked BL on 4.1.2 and now I hate KK and want to go back. Can I just flash a nandroid I have from before I took the KK upgrade?
[Droid RAZR M General] foxdie222:
After downgrading your firmware with RSD lite to 4.1.2, did you have to unlock the bootloader again or was it already unlocked ?
[Droid RAZR M General] dark.blue:
been in KK Bootloader in two days [ a day with kitstalk, a day with gummy -they both really are a great rom-]

BUT, im kind of regret my decision to upgrade to KK bl. there is some "problem" i got in this KK bl, and they are really annoying for me.

The wifi is really weak [in my opinion] and the gsm radio keeps disappearing and then on again... [maybe there is some bugs in the radio function]

So, if i wanna downgrade to JB, all the things in it [radio band, kernel, etc] are the one that JB use to have right? in simple way, i will get my phone back to what its used to be in JB right?

Note:

my phone right now: Xt907, KK Bootloader, Gummy rom, unlock bl, rooted.
[Droid RAZR M General] danielindra92:
Cannot go back to JB from 4.4.2

There is always said "security version downgraded"

I cant flash through using RSD lite with any suggestions u gave.

please help me,, sorry if my english is bad
[Droid RAZR M General] xKroniK13x:
That warning will always display when downgrading but it will work.
[Droid RAZR M General] danielindra92:
It's just stopped and cant continue to the next step.. I have tried but never success..

anyway thanks for the reply

PS: My device is Moto XT907 Locked Bootloader..
[Droid RAZR M General] xKroniK13x:
Try out House of Moto using the Universal script. I've used it (as did numerous others) and it will keep flashing after that warning. Infact, your computer will not display a warning, but the display on your phone will say a warning message while flashing, saying the TZ cannot be downgraded (or something along the lines of that).

http://www.droidrzr.com/index.php/topic/28162-house-of-moto-23/

EDIT: Just saw that you noted you have a locked bootloader... you can't downgrade on locked. Go to the KitKat OTA and unlock that thing!
[Droid RAZR M General] thaddious:
do you have one for the razr maxx hd?
[Droid RAZR M General] xKroniK13x:
Pretty much the same steps, just get the maxx HD fxz.

To downgrade, yes.
[Droid RAZR M General] CrushTheRealMan:
I'm thinking about going back to JB just for the kernel to test a few ROMS, but I use GSM. Do I still need to flash the modem? Or can I just remove it from the .xml
[Droid RAZR M General] 5318008:
I haven't tested this, but I've been told that if you remove the modemst1 and modemst2 lines from the .xml, you shouldn't have to redo the GSM unlock.
[Droid RAZR M General] CrushTheRealMan:
Thanks for the Info. I downgraded using House of Moto and none of the ROMs would boot
[Droid RAZR M General] thewraith420:
Now most of the rom's are using the kk bootloader.

I can't downgrade :(

2/20 flash sbl1 FAIL :(
[Droid RAZR M General] xKroniK13x:
Unlocked bootloader?
[Droid RAZR M General] TheForceUnleashed:
The bootloader needs to be unlocked if its failing at sbl1, which is one of the three bootloader partitions. Best idea would be to RSD to KitKat, root, unlock using Motopocalypse, then do the downgrade.

I've done this downgrade 3 times without fail.
[Droid RAZR M General] foxdie222:
if we unlock the bootloader, downgrade to jellybean, will the bootloader will remain unlocked after downgrading ? if yes, then is there a way to relock it again ?
[Droid RAZR M General] thewraith420:
Once unlocked it will remain unlocked there's no locking it back up. But its the best thing you can do to ensure they can never take root from you and if you don't like the latest ota you'll always be able to downgrade
[Droid RAZR M General] foxdie222:
OTA update on an ulocked bootloader won't brick the phone ?
[Droid RAZR M General] thewraith420:
Nope not at all. But you won't want to rooted when trying to take an ota
[Droid RAZR M General] foxdie222:
thanks mate.
[Droid RAZR M General] LinuxHolic:
Yes, of course :(

You can see the error i posted in this thread :)
[Droid RAZR M General] foxdie222:
After downgrading to jellybean, the system automatically starts to download the system update to kitkat. Is there anyway to stop it permanently ?

Fail at flashing system.img

Thanks for this post. I've been looking for a way to downgrade my Razr M from JB ever since taking the KK update. (KK causes me to lose 4G and sometimes even 3G occasionally, along with other major annoyances.) Your steps have gotten me the closest to succeeding.

My problem is the flash fails at: "16/20 flash system "system.img" -> Phone returned FAIL.

I tried rebooting the phone and restarting RSD, and no go. Right now my phone is a paperweight. Can you help?

---

Update...

I tried flashing system.img manually...

fastboot flash system ...system.img

... and saw a "Invalid sparse file format at header magi" error with a bunch of "write_sparse_skip_chunk: don't care size ###is not a multiple of the block size 4096" errors. Looking around I saw this thread: http://xdaforums.com/showthread.php?t=2749797

The solution looks like it's here, if I, a newbie, can figure it out.

---

Another update...

SparseConverter (from the other thread) failed saying the system.img is not a multiple of 4096 bytes. I used the stats option and it said system.img was 'invalid sparse image format'.
[Droid RAZR M General] thewraith420:
Fastboot flash system system.img -S 0

Or get moto fastboot

Tapatalk'n it from my XT907 (MoKee 4.4.4) on Page Plus Cellular.
[Droid RAZR M General] xKroniK13x:
This. Make sure you are using Moto fastboot or you will get flash fails.

[Droid RAZR M General] afextwin:
I had no errors downgrading, I used fastboot from the latest android SDK.
[Droid RAZR M General] w4y4n:
Does anyone test it yet?
[Droid RAZR M General] AndyBern:
Now that I'm running JB again, I've been reinstalling my apps. But I noticed I can't install anything over (approximately) 20Mb from Google Play Store. It gives me a: Unknown error during application install: "960"

I tried reflashing JB again (98.30.1), and still the same error. Anyone else experience this? I presume the problem is with the image used?

----

Update: It seems the error is not download size related. I could install IVONA text-to-speech, but not Beach Buggy Blitz, Quadragon, X-Plane, or other 3D graphics games. I also can't install Scanner Radio which doesn't use any graphics acceleration (that I know of).
[Droid RAZR M General] thewraith420:
I'd try reformatting internal storage... I haven't experienced that issue and I've been back and forth several times
[Droid RAZR M General] AndyBern:
I discovered the 960 error is due to corrupted data transfers. I have one app that can download modules for itself. When I downloaded a bunch of modules, it randomly gave me a zip extraction failed error (CRC mismatch). On that clue, I tried Play Store again was was able to successfully install apps if I kept trying.

I was able to install all the apps with no problem when I disabled wi-fi to download over 4G. Don't know if the problem is with my wi-fi or the success was due to a much faster 4G connection. (I live rurally, and our 4G is 25-37Mbs effective, compared to my 5Mb DSL connection.) I don't have problems with other devices over wi-fi.

UPDATE:

It seems the wifi problem is with my phone, not my wifi. I was able to twice download a large app (Terminal IDE) over wifi on my wife's identical phone. Her's is still stock, and she wants to go back to JB too, but I'd like to figure this problem out first. My wifi was working fine before flashing.
[Droid RAZR M General] 8on3s:
OK so this may be the same as rsd lite but I need to make sure just to keep things going smooth. Can I use the Linux sbf flash program to perform this same downgrade /without/ using rsd lite? I don't use windows and have no access to either a VM or actual windows machine.

I used the sbf flash tool to bring me back to stock. Just need to see if it will perform a downgrade too, I have not seen any info either direction so help is always appreciated :).
[Droid RAZR M General] :
Just to check: is it ok to modify the downgrade XML to flash VZW 9.8.1Q-66 Jelly Beans? Or is it strictly for 9.8.1Q-94? Need to confirm before risking my already crabby phone (and yes, BL is unlocked), and I would like to know what's the catch like comatose modem.
[Droid RAZR M General] thewraith420:
AFAIK you can go all the way back to ics by editing the xml. I am curious though why go with one of the older jb builds?
[Droid RAZR M General] :
I just don't like the locked-down version of kernel, defeating the point in having root. Safestrap simply died on the latest JB build, but not only that, the build I want is stable (don't want battery to go KA-BOOM).
[Droid RAZR M General] thewraith420:
Safestrap isn't necessary at all now since your bootloader unlocked.
[Droid RAZR M General] :
I know, just mentioning the limitations with certain kernels. However, I successfully downgraded my phone, no more worrying about my phone exploding in my pocket anymore.
[Droid RAZR M General] sbacham:
What does "explode" mean???? Is it mean Battery draining or blosting?
[Droid RAZR M General] :
Bloating - but if your phone's not too hot and battery drain is manageable, you don't have to worry about it. For me, it was a concern. The stock Kit Kat got my phone running too hot for my comfort (I know exactly what to watch out for - I handle the bare Lithium-ion batteries daily - gained lot of engineering experience as well as respect for those batteries). If the battery bloats, STOP USING THE PHONE AND HAVE THE PHONE REPAIR SHOP OR VERIZON TAKE CARE OF THIS POTENTIALLY DANGEROUS SITUATION. Now I got it outta the system. I also am going to have the battery replaced soon for preventative measure (a year old at this point).
[Droid RAZR M General] h20534:
Do you need to be rooted to roll back to 4.1.2?
[Droid RAZR M General] xKroniK13x:
No but bootloader needs unlocked.

Sent from my RAZR M (CM Nightlies) from Tapatalk Pro.
[Droid RAZR M General] :
First root then unlock the bootloader. That's all you gotta do. The downgrading process on locked bootloader will FAIL.
[Droid RAZR M General] h20534:
How do you root when towelroot fails on your device? It just hangs on my device and won't do anything... Is there an alternative way to root other than towelroot?
[Droid RAZR M General] sbacham:
Flash a custom recovery then flash update su.zip from recovery.
[Droid RAZR M General] :
Eh. It won't work. You have to unlock the bootloader first. Custom recovery will never boot from the locked bootloader - I tried it when I was on Jelly Beans - the bootloader was locked up as tight as a submarine's escape hatch. And, you may want to run from factory data reset - I succeed on first try and you MUST have SuperSU app already installed while you're at it and when SuperSU complains that SU is outdated after running TowelRoot, let it update the SU, then you will have the root.

P. S. If you have unlocked bootloader (Status 3 in fastboot BIOS status screen) and custom recovery (AND! With Install apps from unknown source allowed in security settings), all you have to do is simply flash the superuser.zip to the unrooted stock OS.
[Droid RAZR M General] Johnson.21:
