Is there a guide somewhere to reverting my Marshmallow Nexus 5 back to the previous android 5.1.1 while keeping all my apps, data, and settings? I'd like to know what I'm actually doing so real steps with adb and fastboot and twrp would be appreciated, not a pointer to some toolkit that does God knows what behind my back .
Reverting to 5.1.1 appears to be the only way to eradicate the poorly thought out scourge that is doze mode .

Done
You will lose your settings though (all data related to /system partition).

adb devices
adb reboot bootloader

fastboot reboot
When i rebooted i noticed that everything was fine but i had paranoid android rather than stock rom! What happened?
You didn't erase anything and it's hard to say without a log. Follow method 2: http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701
Or use the built-in script (flash-all).

Thanks it worked!
Hello, I registered, hoping that somone maybe could help here.
Yesterday I wanted to get the latest 5.1 update for my moto g, running 5.0.2. Because I rooted the device amd modified some things like uninstalling system apps and replacing system apps with their updates; I wanted to flash a clean system first. I tried to find a german 5.0.2 rom and couldn't find one, so I decided the 4.4.4 version I got should do the same. So I tried to install it via fastboot. For doing this I used these fastboot commands:
Code:
fastboot flash partition gpt.bin
fastboot flash motoboot motoboot.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot reboot
I got these three errors: version downgraded primary_gp, version downgraded for tz, version downgraded for boot.
On reboot the phone get's stuck on bootloader unlocked screen and won't boot. I can reset by long pressing power, I can also enter fastboot menu.
After searching for two hours I could find this firmware XT1032_FALCON-RETDE_5.0.2_LXB22.46-28.1_1_cid7_CFC_1FF.xml (can't post link) and tried to install, I used the same commands as above and finished without any error. But there's still the bootloop. I tried to install several times and tried also to wipe data and cache. Can anyone help or is the phone bricked forever?
Dont flash motoboot, i had this same problem when flashing motoboot
I tried it again without flashing motoboot, with the same result. I think the problem is, that I flashed it once, so I think I could only fix it by undoing the motoboot flash.
Edit: Seems like the problem is only with stock rom. I tried to install CM12 and it is running fine, except it refuses a wifi connection. If CM would run that would also be ok, but without wifi,...so I just need stock.
Meanwhile I'm using a custom rom as a workaraound.
Try on this order @piet85
logo
boot
recovery
system.img1
system.img2
system.img3
nhlos
erase midem set 1
erase modem set 2
fsg
erase user data
and cache
Mind that the commands are not written on the right way just because im lazy :-
Thank you a lot, don't get me wrong, but for the moment I'm very glad having a running system on my phone and it runs very good for a custom rom. So there is no real need to flash again. Maybe I will do so, when there are major bugs or when I have more time, but for the moment the custom rom does it's job.
Although my Nexus 5 is rooted with the toolkit I haven't done anything to it in months (no custom roms or anything)
My phone was working last night but when I woke up and it was in a bootloop.
so i tried fixing the problem myself, here are the things I tried:
- Hitting it (in case the buttons were sticky)
- Flash stock + unroot on the n5 toolkit
- Bootloader>Recovery>Wipe Data/Factory Reset
After that, the boot loop stopped and whenever I try turning it on it goes straight to the bootloader.
So I tried going into the wugfresh advanced utilities and i tried:
- Fastboot Erase*
- Fastboot format*
*flash stock + unroot after both
I have a little bit of hope because I can access the bootloader but I have no idea what else I can try.
Any suggestions?
thank you in advance
Does the bootloader remain unlocked?
Try manually flashing the latest marshmallow. After flashing, boot back into fastboot and run these commands:
fastboot erase userdata
fastboot flash userdata userdata.img (the userdata.img file can be extracted from the stock ROM for flashing in fastboot)
After running the 2 commands, boot back into recovery and perform a full wipe of data and cache, then reboot.

Yup, I'm running windows.
anyways I don't think the nexus toolkit works on any other platform.

So, I went through the method one adb setup and I still have no idea how to do the fastboot erase userdata
nvm got it.
Were you able to boot the phone?
I'm in the same situation and need help
I got an OTA update for marshmallow. At this stage phone was locked, unrooted and not tampered with.
After updating OTA phone went into a bootloop.
'Allow OEM Unlock' is disabled from developer options before even updating OTA so bootloader can't be unlocked.
After bootloop, from bootloader using fastboot (and mfastboot also tried) I flashed "XT1550_OSPREY_RETASIA_DS_2GB_6.0.1_MPI24.107........" this marshmallow firmware using standard commands for newer Moto devies. Even after flashing firmware, still bootloop happens.
Code:
fastboot flash bootloader O:\MotoG3\Firmwares\bootloader.img
fastboot flash logo O:\MotoG3\Firmwares\logo.bin
fastboot flash boot O:\MotoG3\Firmwares\boot.img
fastboot flash recovery O:\MotoG3\Firmwares\recovery.img
fastboot flash system O:\MotoG3\Firmwares\system.img_sparsechunk.0
fastboot flash system O:\MotoG3\Firmwares\system.img_sparsechunk.1
fastboot flash system O:\MotoG3\Firmwares\system.img_sparsechunk.2
fastboot flash system O:\MotoG3\Firmwares\system.img_sparsechunk.3
fastboot flash system O:\MotoG3\Firmwares\system.img_sparsechunk.4
fastboot flash system O:\MotoG3\Firmwares\system.img_sparsechunk.5
fastboot flash system O:\MotoG3\Firmwares\system.img_sparsechunk.6
fastboot flash system O:\MotoG3\Firmwares\system.img_sparsechunk.7
fastboot flash modem O:\MotoG3\Firmwares\NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg O:\MotoG3\Firmwares\fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot reboot
pause
At this stage, phone still goes into a bootloop. Clicking on recovery from bootloader also sends phone into a bootloop so can't even access stock recovery.
Also no way to erase system as bootloader is locked.
In bootloader some details are given:
baseband- M8916_2020617.29.03.21.45R OSPREY_APAC_CUST
product- osprey xt1550 16gb p2b
cpu- msm8916
device is locked. status code 0. software status official.
How do I get the phone back in working state?
Other bootloop guides were not useful as here even after flashing stock firmware phone still goes into a bootloop. ALso no stock recovery is accessible and BL is locked
Using the guide in http://forum.xda-developers.com/2015-moto-g/general/guide-fastboot-flashing-factory-t3187750, it is suposed to work (but you can't enter in stock recovery to do a factory reset, right?).
Try one more time, and confirme you flash all the system.img_sparechunk's files (some firmware images have less, and some have more).
In the first boot, the device can take a long period of time to boot (10-15 min in some cases).
If you can boot the recovery or the system, do a factory reset.
did you get it working?
Hi, this is my first time making a post, ok here's the thing, a couple of days ago my phone run out of battery, when i come back to charge the phone, this just get stuck in the Motorola logo and don´t turn on, i never make nothing like root or flashing roms, the phone os was all stock Android 5.1; so i look in the internet for possible cause and i find that it was a bootloop, i try to get in to the fastboot flash mode to make a reset with the factory option but just get directly to the motorola logo and dont do nothing, so a try with the recovery option and gets in to the android system recovery <3e> and try the wipe data/factory reset but doesn´t work. I try even via computer using the minimal adb and fastboot to erase the cache and the userdata with the commands and doesn't work, still appearing the motorola logo. so i found that i have to install the original rom again but first ill have to unlock the bootloader for my device, so i did it, i unlock the bootloader and now appear <Device is UNLOCKED. Status Code: 3> and now appear the poster WARNING BOOTLOADER UNLOCKED instead of the motorola logo; then i search for the stock rom for my device and i find this one XT1040_PEREGRINE_RETBR_5.1_LPB23.13-8_cid12_CFC.xml.zip (i know that my device is peregrine because i remember saw it before in the settings but not remeber the hole name), so i make the installation with adb tools like the post say and make this commands:
fastboot flash partition gpt.bin
fastboot flash motoboot motoboot.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot reboot
when its over i press fastboot reboot, but then appears again the WARNING BOOTLOADER UNLOCKED poster, i try to make it again, bus still appearing, i try more than 10 times, but still appearing.
sorry if the post is too large but i try to explain everything so you guys can help me because im desesperate with this, thanks.

If your goal is to re-lock the bootloader: try the command: fastboot oem lock
However, I don't see that solving your problem and may compromise your ability to restore to stock. Instead check this link and follow the install directions EXACTLY:
http://forum.xda-developers.com/moto-g/4g-development/rom-stock-motorola-4g-lollipop-rom-t3142816
eg. for Canada choose: XT1040 (Note: for Rogers/Fido - confirmed)
Retail Canada 5.1 ROM (Untouched) (531mb) [Download]
i.e., you want the untouched version for your specific region.
Good luck. S
