I wonder whether there is help for someone who thought he knew how to flash a kernel but apparently is deluded. I have the original nexus seven Wi-Fi tablet android version 4.3 build number JWR66V. The system still wants to update me to 4.3 because I ripped some files out of the cache directory to prevent OTA updates. I have both fastboot and adb. I have read the stickies about flashing.
The phone is rooted and the bootloader is unlocked. I use TWRP custom recovery, and it's a good thing, because I solidly bricked myself up just trying to get my lollipop. I know there are tools to root a nexus seven even with stock lollipop, so I thought I'd upgrade my phone to stock lollipop and then use one of those methods. I tried both the stock lollipop kernel and the one provided by chain fire, which I understand is rooted already. (I'm assuming upgrading to lollipop will lose me my root, unless I want to recover back to 4.3.)
I tried to do these things a couple of different ways. When I tried fast boot, I got the message "error: neither -p product specified nor ANDROID_PRODUCT_OUT set". There was a YouTube video suggesting how to deal with this error message. I'm pretty sure I followed the instructions but no go. (I was using the "flash all" command.) This was after I had put the file containing lollipop in the directory, both zipped and unzipped (so that I had an .img file instead of a zip file). I tried using both the zip file with all of the lollipop partitions and the system image file individually. No go. I also had a message that android-info.txt could not be found, even though it was in the same, working directory.
I could be wrong but I don't think you can install a complete updated kernel from a file on the device. I think that works only with update.zip.
I'm still thinking fastboot is my best bet, but there are dependencies apparently and I don't know what files to include in its directory. Then, am I wise to go to stock and then root, or should I simply flash the stock kernel already rooted? I assume that's what chainfire is providing, correct?
I notice the lollipop official ROM nor Chainfire’s supposedly-rooted image have any file named nakasi. I have only .img files, no .zip files.
I found a dozen sets of instructions on how to flash a kernel but something I need is missing from all of them. Does anyone know what it is or can anyone offer some helpful advice?
Thank you,
Leon M.
Hey...Help me with this..
I tried to root my moto g4 plus using temporary twrp so that i get system updates,It is not working out.
I have used moto g3.. and used this same method for rooting and is successful..
In g4 plus till the last step i.e untill u need to flash supersu it works but there comes error.
Every data is lost and i have to boot into my custom rom backup...

Can I request some more details please?
OS version?
TWRP version?
Did you unlock your bootloader and enabled OEM unlocking in Developer Settings?
Which rooting method did you use (e.g. did you flash ElementalX kernel https://forum.xda-developers.com/moto-g4-plus/how-to/guide-how-root-nougat-moto-g4-plus-t3484672 or the superboot method https://forum.xda-developers.com/mo...t-how-to-root-n-firmware-npj25-93-11-t3532556) ?
What error do you get?
EDIT - I understand you're desperate for help resolving this, please don't post the same thing in 3 places if you can.

Here it is
I did not use kernel
Oem done
twrp-3.0.2-0-athene
SuperSU-v2.66
My error was that I could not get booted back on...
It would not turn on..
Then i downloaded another stock rom from xda and got back...im xt1643
All steps are followed until flashing of supersu..The error comes there..is there any xt 1643 users who could suggest a correct reliable and error free method for this

Couple of things:
Try installing the newer TWRP from here: https://forum.xda-developers.com/mo...covery-twrp-3-0-2-r3-moto-g4-g4-plus-t3494337
I don't think TWRP 3.0.2 is supported that well.
SuperSU - use the SuperSU 2.78 or the beta https://forum.xda-developers.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133
I think if you desire root, you'll need a modified kernel (so far, it appears that the stock kernel security prevents rooting, someone correct me if I'm wrong), which may explain the bootloops. Try with the ElementalX kernel method as linked above, seems that people have had luck with it. https://forum.xda-developers.com/moto-g4-plus/how-to/guide-how-root-nougat-moto-g4-plus-t3484672 You may need phh's Superuser instead.

If android o does arrive, I imagine you'll have to revert back to the stock ROM to update, so removing root and flashing your stock boot image over your existing installation. Alternatively you could fast boot a stock ROM to restore a stock install.
What's the rush anyway, no announcements have even been made for android o...?

I see you've already gotten an answer from tywinlannister regarding this question https://forum.xda-developers.com/showpost.php?p=71265934&postcount=249
I don't see much to add to his well thought out reply except if you're staying with stock (assuming you're using temporary TWRP):
1) Unroot completely using the SuperSU settings panel or follow the unrooting instructions for your superuser app.
2) Reboot into temporary TWRP, restore your boot.img (if you flashed ElementalX kernel) from within TWRP (if I recall, it's Restore >Select image and then assign it as a boot image). If you did not make a backup of your boot.img, there are images around (e.g. https://forum.xda-developers.com/moto-g4-plus/how-to/1643-indian-version-stock-boot-modem-t3460615 - i don't know if this is for nougat or marshmallow - download and extract the rar file, copy the extracted boot.img to your device and boot into temporary TWRP, then flash the boot.img).
3) Reboot and you should be fully stock - with stock kernel/boot.img, recovery and no root.
1a) As tywinlannister linked, you could just reflash the latest fastboot image which would remove root and give you a stock boot, which would be the best for reliability (which as of this post is this: https://forum.xda-developers.com/moto-g4-plus/how-to/moto-g4-plus-xt1640-43-athene-npj25-93-t3549369)
Thus, when/if Android O does arrive, you should be able to update via OTA. It's gonna be at least 6-12 months away for the update, if previous Android updates have been anything to go by.
OK Please note (4-25-17) this message is a work in progress, as I slowly restore my system.
This is a listing and hopefully helpful listing of what I did (right and wrong)
in upgrading my Systemless-rooted (suuser) phone from 6.01 to 7.00 (nougat)
# 1. it did not work, and I went back to 6.01 successfully using the twrp recovery
I have previously used Bender's guid (here) to get the system-less root on 6.01.
essentailly, here's the best plan. Use the Minimal ADB and Fastboot package (MADB &F) (here)
(Explanation: the MADB&FB package will allow you do do LOTS of stuff related to updating your phone, with very little grief.)
it also includes the ability to automatically "push" a package over your usb connection if the ZIP file doesnt load right. **THIS will come in handy later!
Once MADB&F is installed, make note of your directory, and then make sure you start your dos window (for pc users) as an administrator!
BTW, if I HADN'T made the "TWRP backup" of my system, I'd be Sh*t out of luck right now...", because I screwed up the 7.0 upgrade.
the technical problem was that I had no data, no modem, no way of getting data/voice in/out.
SIMPLY using the TWRP restore fixed me!!!
(so far, we have MADB&FB, downloaded and bender's (chainfire) rootless guide.
Next you want to download the current firmware image for your phone. This will be a lifesaver, I promise!
3) Download a TWRP image (this will MAGICALLY load on your pc when you tell it you need help! Look HERE
(Athene is the Motorola Codename for the motoG4+)
3) copy the athene TWRP image into your madb&FB directory to make it easy to load
4) next, (you still haven't touched your phone yet, you realize: (skipping some basics here, you can search here on XDA to find more info)
a) plug your phone into your pc
b) make sure you are a developer
c) make sure your phone shows you are connected to your pc for file transfers, NOT for charging
5) in your MADB&FB directory, (aka a dos/(admin) window) type the following:
all commands at this point will take place in whatever directory you installed Minimal ADB & Fast boot (MADB&FB)
Connect your phone to your PC and open MADB&FB, check the connection with:
adb devices
return should include your "serial-no" and "device".
6) next, on pc, tell the system to reboot your phone to the bootloader!
Reboot into bootloader with:
adb reboot-bootloader
and check again with:
fastboot devices
7) Next you are going to download TWRP to your phone (not permanently, just for a bit!)
fastboot. flash recovery twrp-3.0.2-0-athene.img
Now you have TWRP (Team Windows RECOVERY PROJECT) loaded.
SO.. THIS is where you create a backup of your current stuff using the backup options.
NEXT:
take the suUser2.78 (stateless rooting), and once your backup is done, install it from TWRP
Then (I was) back to 6.01 rooted.
NEXT: 7.0 and then rooting... (will update tomorrow)
did a successful upgrade to 7.0,
then unsuccessfully tried to sideload supersu2.78, which bricked loader
then downgraded again to 6.01 (and rooted again, ok)
will continue tomorrow.
need working phone for now..
cheers to all, and to all, a happy spelunking!
You can't root factory Nougat as is, it is well encrypted.
You need to replace first the kernel with the ElementalX one, or you will end up with bootloops.
Only after that you can do SuperSU, but only with the latest beta.
A few pointers from your story:
1)As you've found out the hard way, you won't be able to update to Nougat if you have root and/or TWRP, because the update requires a stock system - stock recovery, system and no modifications (bootloader status doesn't matter). In other words, you'll need to unroot and restore your stock recovery - might be easier to reflash the stock system, probably the quickest way to flash a stock ROM (and update to Nougat) is to use the fastboot ROM. https://forum.xda-developers.com/moto-g4-plus/how-to/moto-g4-plus-xt1640-43-athene-npj25-93-t3549369 Of course, this will remove root and TWRP, as well as potentially wipe your data, so back up accordingly. This should flash the NPJ25.93-14 build on your device, which appears to be the latest global build.
1a)Also, if you flash Nougat this way, your bootloader and GPT partitions will be updated, so if you wish to downgrade to Marshmallow at any point, when flashing do not flash these partitions from the Marshmallow ROM. Fastboot should stop you, but a brick may occur if these get flashed.
1b) You may find in the Guides section TWRP backups of Nougat builds, I don't recommend using these to update your system with. Granted, they have most of the Nougat system in a TWRP backup, but some crucial firmware (e.g. the baseband) is not included, and may cause you issues if your device is not formally flashed to Nougat.
2) As SoNic67 has already mentioned, the stock kernel security will cause your device to bootloop should you choose to try to root following the Marshmallow method. If you wish to use SuperSU, follow this guide: https://forum.xda-developers.com/mo...de-root-moto-g4-plus-supersu-android-t3587918 You may wish to use a more up to date TWRP than the official 3.0.2 (I recommend shrep's TWRP 3.0.3 n4 here:https://forum.xda-developers.com/mo...covery-twrp-3-0-2-r3-moto-g4-g4-plus-t3494337) Whatever you do, ensure you flash first the ElementalX kernel before you flash the SuperSU v2.79 SR3 beta (https://forum.xda-developers.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133), or apply the systemless fix with earlier SuperSU versions as directed in the aforementioned rooting with SuperSU guide. Else you'll be having bootloops or your device will not boot whatsoever. Here's my steps in successfully rooting Nougat: https://forum.xda-developers.com/showpost.php?p=71817346&postcount=225. Good luck either way.

After updating my US retail xt1644 to nougat, by restoring totally-stock marshmallow then taking the OTA, I wiped data and made a *complete* TWRP backup using @Shreps' unofficial 3.1 TWRP build (https://moto.shreps.fr/Moto G4 (athene)/recovery/twrp-3.1.0-athene_shreps.img).
This version of TWRP allows backup/restore of the full set of firmware partitions including baseband, DSP, etc.
In other words, I believe the TWRP backup folder in the following .zip file provides a one-stop path to the latest xt1644 USRET firmware by doing a restore from TWRP 3.1.0.
https://drive.google.com/file/d/0B4XobQzgZVHyRTlmSDMtYkdZeUU/view?usp=drivesdk
My only uncertainly is if the ota process modified the partition table in a way that might make this backup image incompatible with the xt1644 still in the marshmallow state.
I've often wondered if I (or a more skilled enthusiast) couldn't build a TWRP-flashable .zip that would setup the partition table, update the baseband, etc. This is what I've grown used to from devs on other phones I've had, but perhaps there's something about the way moto does things that makes this problematic.

Nice one, hopefully that'll help more XT 1644 users I'm still not sure if TWRP can backup/flash the baseband by itself, but I don't have a XT 1644 to test. I imagine your backup will need a clean flash (wipe data/cache/Dalvik) to work?
The OTA process does update the partition table, but as far as I know, that should not prevent you from flashing back to Marshmallow/Nougat as you wish, so long as you did not try to downgrade the GPT/bootloader.
There was an effort to create TWRP flashables of the stock ROMs a little while ago (you can see the thread here: https://forum.xda-developers.com/moto-g4/development/fxz-athene-twrp-flashable-fastboots-t3562147) which if I understood it created flashable radios and ROMs from the firmware files we have. We can't touch the GPT/bootloader since, as I recall, you need a signed stock firmware to do so (and besides, downgrading GPT might be asking for a brick). I recall some users mention they were able to run Nougat TWRP flashes on the MM bootloader/GPT without issue.
There were issues with simply flashing the Nougat 93-14 radio baseband files for some US users, losing LTE in the process and appears the only resolution was to flash the stock ROM - I don't know what the cause was (perhaps no/incorrect CDMA support in the radio files?). Your TWRP flash is from a US based phone so may have better luck in that department, and will likely behave on your device since that OTA has updated all the firmware on your device that TWRP isn't able to touch. I still am not sure if we can use this TWRP backup to update on a MM device without issue, but only one way to find out...
Alright so I apologize in advance if this thread has been posted a million times and believe me, I've spent the last 4-5 days combing through to make sure I could get every detail of this process done correctly. So I'm not just blindly asking for instructions on how to root my phone. Apologies also if I posted this in the wrong place.
For starters, I'm using Moto G4 Plus XT1641 6.0.1 Build Number MPJ24.139-23.3. My carrier is Koodo in Canada (unsure if that's important but I'll need to being it up again for another point). The files I downloaded were from a youtube tutorial and this includes ADB program, TWRP img 3.0.2.0, supersu zip 2.46 and Motorola Drivers 2.5.4, SOME of which I think may have been outdated versions.
So Saturday night I tried to root my phone with those files. I followed some more guides, I unlocked my bootloader and I think I mostly did everything right except for getting the right supersu version as I've seen up to version 2.82. I think this may have been my first mistake but maybe someone correct me if I'm wrong? My other mistake was not making a backup in TWRP. I'd read about possible wifi problems after rooting so I grabbed the elemental package and possibly even flashed that wrong. I can't even remember the steps of what I did but I'm sure it was all wrong.
Main point, after all that I didn't have ccell service, wifi, etc. The common problems that arise when you do it wrong. I ended up just taking my phone in and getting a new phone. Exact same one, same model. And this brings me to where I am now. I've downloaded some new files and I want to make sure that I've got everything right as to avoid misunderstanding some key parts to the process.
Minimal ADB and Fastboot 1.4.2, twrp-3.1.1-0-athene.img, SuperSU-v2.82-201705271822, Motorola Drivers 2.5.4, and lastly XT1641_ATHENE-TELUS_MPJ24.139-23.3_cid50_subsidy-TELUS_CFC.xml. Notice how that last one says Telus? It's the parent company of Koodo so I'm hoping I can use that as a failsafe.
I think I've covered all the key points so to sum up:
1. Did I use the wrong supersu zip version and could that be a reason why I had no wifi/cell service? Is that also possible because I may have flashed the wrong carrier athene file?
2. Are the files I have downloaded now the correct ones I need and up to date?
3. I'm following this guide. With the files I have downloaded, is it still a correct step by step process? Are there other guides that work better?(thats not a knock on the original guide I'm refering to). https://forum.xda-developers.com/moto-g4-plus/how-to/root-systemless-rooting-supersu-2-74-2-t3405772
I think I've got the right know how and tools to root my phone but I'm just nervous of doing what I did before again and would like some reassurance that I'm doing it right. I've just come from jailbreaks, the world of root is much different. I appreciate any help or tips you guys can throw me!
Hmm, that's odd how you lost radio signal when you rooted, did you obtain radio signal back after you unrooted?
A few things I noted:
1)You may wish to update your device to a newer build, you might get an OTA inviting you to update to MPJ24-139-63 (or 139-64), which was the latest Marshmallow build. Once you've rooted, you will not be able to install OTA updates until you have unrooted and restored the stock recovery (from the same build as you currently have). If you get an OTA notification for any build beginning with NPJ, that's for Nougat.
2)If you plan to stay on Marshmallow, you don't need the ElementalX kernel - a custom kernel like ElementalX is compulsory on Nougat, whereas Marshmallow is not as strict with regards to rooting.
3) I hope the carrier ROM is okay, though from other reports, flashing the incorrect ROM can corrupt device partitions, leaving with no IMEI/no service/no FP. We have possible ways of repairing that though.
The tools you've downloaded seem to be okay and Bender's guide is still okay - even though the tools they've used are out of date - so the general procedure would be (up to you if you've updated MM at this point):
Install adb on your computer.
Boot your device to the bootloader.
Flash TWRP 3.1.1 athene (either the offficial TWRP or an unofficial build from shreps or oadam11) as directed.
Reboot to recovery (to make sure the recovery sticks).
Back up all partitions on your device, make the name descriptive.
Make another backup of the boot partition - this contains your stock kernel, useful for switching root manager.
Once the backups have been made, flash SuperSU v2.82.
Wipe cache/Dalvik
Reboot.

Thanks for the reply, it helps me feel a little more confident in what I'm doing. I didn't get my cell service back as I just took my phone into Koodo and they just gave me a new one. A few questions.
Are there some clear guides on how to recover from lost wifi and cell service? I've seen a few but it appears they all have different directions so as a newcomer to Android it does seems a bit confusing to what the right way to do it is. I'm also hoping someone can chime in on the Telus carrier IMG file as that seems to be my backup in case anything goes terribly wrong again. I'd hate to have to bring my phone back again a second time. Also, is it an easy process to make a backup of the kernel in TWRP? I've figured out how to make a backup of the normal partition, just hoping backing up the kernel is just as easy.
I think I'm near ready to take the root plunge in the coming days. It's good to see such a strong community here. Totally different from the jailbreak scene.

Hmm, I'm not aware of any guides specifically dealing with lost Wi-Fi and lost mobile signal. There are a few posts where we've had some success in getting radios back, but it involves either hex editing https://forum.xda-developers.com/showpost.php?p=72340548&postcount=98 or flashing hw, modem or fsg partitions from a working device (in this case, XT1641) The instances I've seen of lost Wi-Fi/mobile signal appear to have occurred during a stock ROM fastboot flash, but hoping someone can chime in as to whether it was just flashing the wrong region firmware or something else.
If you want to back up your kernel in TWRP:
Boot to TWRP
Tap 'Backup' on the main menu
Select only the 'boot' partition - this is the partition that contains your kernel (should be stock and clean if you've not rooted).
Rename the file to remind you it's your kernel.
Swipe to back up.
If you need to revert to this kernel, unroot first (depending on your root manager, you may have to boot and then unroot. I recall SuperSU unroots via the SuperSU app settings), then boot to TWRP.
Tap 'Restore' on the main menu
Navigate to your boot backup
Flash your boot backup
You should now have a clean stock kernel, so if you wish to switch root managers, you should be able to obtain root with your new root manager. We want a clean kernel (no modifications made) since uninstalling the old root may leave traces of root on your existing kernel, and thus may cause issues if you re-root with a different manager.
Good luck in rooting

Hmm, I'm not aware of any guides specifically dealing with lost Wi-Fi and lost mobile signal. There are a few posts where we've had some success in getting radios back, but it involves either hex editing https://forum.xda-developers.com/showpost.php?p=72340548&postcount=98 or flashing hw, modem or fsg partitions from a working device (in this case, XT1641) The instances I've seen of lost Wi-Fi/mobile signal appear to have occurred during a stock ROM fastboot flash, but hoping someone can chime in as to whether it was just flashing the wrong region firmware or something else.
If you want to back up your kernel in TWRP:
Boot to TWRP
Tap 'Backup' on the main menu
Select only the 'boot' partition - this is the partition that contains your kernel (should be stock and clean if you've not rooted).
Rename the file to remind you it's your kernel.
Swipe to back up.

That's perfect thank you so much. Am I right to assume that if I get into a jam then I can just restore/reflash my backups and I'll be back to normal?
To be safe, flash the ElementalX kernel before rooting.

See this is where I get confused, the guy above you said ElementalX isn't needed on Marshmallow but you say i should use it anyway? I've seen a few differing opinions on what should and shouldn't be done, just not sure which one is the right answer.

ElementalX v0.07 is not required on Marshmallow (provided you are planning on staying on 6.0.1), you can root the stock ROM kernel. You may wish to flash the ElementalX kernel anyway as this custom kernel gives you more control and tuning options compared to the stock kernel. On stock Nougat, because the anti-rooting kernel security is much stricter and enforced (whereas on Marshmallow I don't think it's enforced), then you need ElementalX or vegito or a custom kernel to bypass the security, by in effect replacing the stock secure kernel with a kernel that doesn't have those restrictions. Without replacing the stock kernel on stock Nougat systems, you can run into a bootloop.
As an MM kernel as mentioned before has weaker security regarding rooting, it's up to you if you choose to root the stock kernel or ElementalX.
I've rooted MM (MPJ24.139-63) in the past with SuperSU (v2.79) and only used TWRP and SuperSU.
In response to your other post, the backups should get you out of a jam, since what you're doing should only affect the partitions you've backed up previously (they in theory shouldn't go anywhere near your modem, bootloader or critical firmware). Bear in mind that the TWRP backup if restored in full will revert your messages and data to that backup. You may wish to use Titanium Backup or other tools to take occasional snapshots of your apps data that you can restore should you have to roll back.

If you're on Nougat, then you should use ElementalX. If you're on Marshmallow, you don't need it.

Right on, I think I feel comfortable with this now! One more question though, with newer versions of SuperSU is it still necessary to make the command echo systemless=true or was that mostly for older versions? Also if that part is needed, should I run SuperSU from the data folder in TWRP?

The 'echo systemless=true', as I understand it, isn't required on SuperSU 2.79 or newer, so if you're flashing 2.82, you should be able to flash as is without having to run the command too Also makes uninstalling easier!
Hi, i just got the moto g5 plus, i always have phones that from the moment i bought them they wouldn recive any updates, so i realy didnt care if unlocking the bootloader installing new recoverys will affect the OTA updates. So i have a couple of questions.
1- first i want to at least have a stock firmware just in case, but i cant figure out which one should i download from here
firmware.center/firmware/Motorola/Moto%20G5%20Plus/Stock/
Before i always use sammobile.com and it was really easy to found a stock firmware from Argentina. My compilation number is: npns25.137-15-11 this means that i suppose to download that one XT1681-XT1683_POTTER_BRASIL_LATAM_MEXICO_7.0_NPN25.137-15_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip ?
2- it is possible to unlock the bootloader and root your phone without installing a new recovery? i was reading some post and when you change your recovery or you modify something the OTA update will stop working. they are some methods like the magisk but they seem i little bit too complex for me and i don't want to do it every time that a new update is available.
thanks for the help, and sorry for my English i am from Argentina.
1. yes, but any build will flash and run, so it doesn't really matter that much...
2. Nope. You need to flash TWRP in order to root. This is because the stock recovery will only flash signed images... You can use Magisk, after backing up a stock build. Anytime there is an OTA, just restore to that system image, Flash the original recovery via fastboot, and then take the OTA. Once you have it, flash TWRP again, and restore to your other build. Or just run a custom room like Lineage or RR, and this whole thing isn't really an issue anymore.

yeah i know i had a samsung galaxy s3 until now, and i always have cyanogen, slimrom or now lineage, but this is the first device that i have one that will get updates (at least 1 more :S) and i want to seize that
i will start downloading that file just in case
1- ok so unlocking the bootloader doesn't affect updates only when you modify files? when the update is installing is basically comparing the files that you have with the ones that you suppose to have and if there is something different it will fail? its something like that?
2-dumb question how do you do a full backup in the stock recovery there is no option no do a nandroid backup or it will appear after i just unlock the bootloader?
