I want to make a clean Install of factory image (Android 8.0 Oct) on my Nexus 6P with TWRP.
Should wipe Dalvik, Data, System and Internal storage, then move the stock zip file (That I downloaded from google's web) from my computer to my phone and just install in TWRP? Will it work?
Device is unrooted, only has an open boot loader, I just want to make a clean install of Android 8.0
If you wipe your internal all your downloads and your factory image are gone.
Sure you can flash the unpacked *.img with twrp, but don't try to flash the bootloader or radio with twrp.
If you really want a clean start and wipe everything, then you should flash the factory image with fastboot. This will update your bootloader and radio too.

Hi coremania, I have a few questions towards this method.
1. If the stock image is stored in either external SD card OR USB OTG, even then will there be any problem installing the the stock rom back using TWRP?
2. If the boot loader is unlocked, should one has to re-lock it first before reinstalling the stock rom either thru' TWRP or thru' Fasboot commands?. and finally,
3. Is it not advisable to flash the stock rom from the full factory image using TWRP rather than Fastboot?
(As I think it is easier to flash thru TWRP than typing those ADB commands in Fastboot).
Thank you for your inputs.

If you decide to flash and test some stuff the bootloader should be always unlocked. If anything will went wrong and your bootloader is locked you're mostly f***ed. Never relock your bootloader until you want to sell your device.
I mostly use flashfire to flash stock and custom roms, TWRP is ok too, but it's easier to keep root and TWRP with flashfire by flashing stock images. Do not flash bootloader and radio with flashfire, never ever !!! There are TWRP flashable zips for bootloader and radio here on XDA, you only should use these with TWRP, but the safe way for bootloader and radio is fastboot for sure. Fastboot is the safest way for flashing stock,
but not absolutely necessary, you have to decide this for yourself.
Edit: to your first question, I never flashed with USB otg on the n6p, but I think yes it should be fine.
I hope someone here can help answer this question. I also want to flash factory image version 8.1.0 on my nexus 6P. But somehow my phone is not recognized by any computers I tried to plug it in. When I plug in the usb cable to the phone, it doesn't pop up the usb notification to choose MTP for file transfer. Then I try with Developer tab in Settings to choose it manually (USB debugging is enable) but it still doesn't work. My laptop has been updated with android usb drivers and other stuffs. I have a second phone (Oneplus 1) and it's recognized by my laptop the moment I plug it in. Please suggest any solutions to fix this. Thanks everyone.

Check your cable, or try a different with different port.
In the Dev options you can reset the debugging options, i guess a reboot is necessary afterwards.

Thank you for the clarification. So, far I have not faced a situation to flash my custom recovery either thru' TWRP or thru Fastboot. Instead, I am using my Nandroid backups taken from TWRP and using it to restore my system after I try a custom rom OR upgrade my system with the latest Magisk version for a systemless root. So far there are no issues. But, I wanted to be aware of the methods to go back to stock (without any user installed apps/data) if need be. I read in some forums that we need to re-lock the unlocked bootloader if we want to go back to stock rom using fastboot. Otherwise, the system will not be installed alright and might cause a bootloop.
That's why I wanted to clarify.
Thanks again for your inputs.

You don't need to ever relock your bootloader. If you want to try stock and use TWRP try SuperXe 8.1. It's just flaahable stock with some extras you can opt out of your not intereseted.

I can't confirm the relock and unlock method to go back to stock. Senseless to me.

Hi, I am not too sure if I posted this in the right place or not but please let me know if it is posted in the wrong place. I am actually relatively new towards rooting of an android device so i need to clear my doubts.
I used Wugfresh toolkit to root my Nexus 10. The toolkit also have an option to install TWRP. But the version of TWRP is not the most updated one. So, can I just download the latest one and flash it or i need to remove the current one before I can update the version.
Also, I am interested in flashing a custom ROM. But my question is if a new stock firmware is out, how am i going to update to the latest stock firmware when I am in a custom ROM.
Please let me know if you don't understand my question. I will try my best to explain further and also thank you in advance.

TWRP typically recommends installing and updating their recovery via Goo's app thing, but if you know where to look (openrecovery on goo + manta), you can get the .img and then flash it with fastboot. I usually do fastboot erase recovery and then fastboot flash boot TWRP-IMAGE.img. But if you don't feel too comfortable with fastboot, then Goo's program should take care of it I think.
If you want to try the latest stock when you're using a custom ROM, you'll need to flash the latest factory image from Google to go back stock, and then update it (unless the factory image is updated to the latest, which doesn't usually happen till days later). Just want to make sure you backup anything important.

So, for TWRP, it means that I can restore the stock recovery before I flash the TWRP img right? Because I am using the Wugfresh toolkit to run all these fashboot commands and they only have the options to either flash a custom recovery or to restore the stock recovery.
As for the custom ROMs, every time I flash a ROM, all my stuff in my Nexus 10 will be gone right? For example my game progress etc. Because if I were to backup, I will make a nandroid backup which means every single thing in my nexus. So, correct me if I am wrong. Every time I flash a ROM, my nexus will be back to a clean state right?
Thank you in advance for your answers. ^^
I installed a custom rom, decided I wanted to go back to stock by restoring from TWRP, now in bootloop. I can boot into recovery and bootloader via the phone but my PC does not recognise that it is connected via bootloader. Is there a way I can rescue my device?
I have build B29M, and noticed there is a zip version of another build on this forum which I could have installed through TWRP, but would that make things worse?
Thanks for any advice..
Stupid question probably, as you've already installed a custom ROM, but you do have the fastboot drivers installed on your PC?
Yes it all worked before, I think it's because the phone must have defaulted back to not being in Debugging mode, and I can't access the OS to enable this mode.

Well, if you can reach recovery, flash another custom ROM to get the phone usable, then flash back to stock, looking at points 11 and 12.
I managed to fix it, for anyone who may encounter similar issue in the future...I tried restore again from TWRP but this time did not select Vendor Image, only Vendor.
I have this same problem, my PC doesn't see the phone when I go to bootloader and I can't fastboot at all. I can use my phone regularly copy files over. I already flashed to a new ROM from cataclysm to purenexus but still can't fastboot.

Quick question.
I flashed the radio in my 6p.
Can I install the latest OTA Android update over that or do I need to go back to stock?
Also my phone is unlocked, does it need to be locked?
The radio flash didn't solve my problems.
Anyone?
Which radio did you flash?

There's a lot about your config you haven't told us. Since you're staying your phone is "unlocked", I can only assume you mean the bootloader is unlocked, and you've got a custom recovery (TWRP) installed. If this is indeed the case, then no you should not take any "OTA" as any changes to "stock" (like a custom recovery) will cause it to fail.
You can, however, wipe and flash new Roms through twrp, or with an unlocked bootloader you can download the latest image from Google's sure for our device and flash that through fastboot (Google search to find tutorials on this there's a million of them). Be aware this will wipe EVERYTHING out on the device and reset it back to defaults (your data, recovery, etc.)

If you didn't flash a custom recovery you can download the ota without any issues. This is assuming that everything is still completely stock about your device. You can upgrade and downgrade your radio as you wish. I would advise to keep your bootloader unlocked so you can fix any problems if you ever have any.
I've posted in a few places here on xda but no responses yet, please help! I've unlocked bootloader, rooted, installed twrp, tried to flash cm13 but had the wrong gapps, so it failed, I tried to wipe and restore a backup I made in twrp but it says my device is corrupt then halts at the Google logo. I think all I need is to push the correct gapps to the phone through adb but I can't get my stupid pc to recognize it anymore. I boot into twrp, plug it in to the pc, tried multiple tools and sdk adb route, but nothing works! I have all the drivers installed, and reinstalled, keep getting a Windows error "The procedure entry point WSAPoll could not be located in the dynamic link library WS2_32.dll"
I read somewhere that the ws2_32.dll is only available in Vista and up... I'm running xp, I wonder if that's my problem. Sorry for all the posts and long explanations, I'm just frustrated and need professional help
You could get that dll somewhere and add it to your windows. I never flashed under Win XP... Also, you could try to download the factory image (NRD90U) from google. Boot your phone on fastboot mode and flash all the .img one by one and should be back to stock... That should fix your problem hopefully!
How do I boot into fastboot mode? I can get to the ko'd android and select options and get into twrp, it says download mode disabled and connect usb data cable, which doesn't change when I plug it in but I see my serial under fastboot in the skipsoft tool kit. I mainly get that error message when using that tool kit too

If you're running XP your pretty seriously out of date.
All of them say download mode disabled when you are in your bootloader. If you see the little droid on his back and the ascii device status in the bottom left corner of your screen you are in bootloader (which is fastboot 'mode' as you put it). Since it is returning your serial number it sounds like you're good.
I expect you may want to simply reflash the stock OS from your Skipsoft kit. Get it booted stock first, then install a custom ROM.
Ok thanks, got my bro here with his win 7 laptop, gonna try and see about pushing the correct gapps to the phone first, if I can't get adb to work when booted into twrp I guess I'll try the fastboot method to stock.
Is it safe to use the Skipsoft toolkit to flash stock Rom while I have twrp installed? And unlocked bootloader?

If your device is currently borked, just start from scratch. If you flash the factory image partitions properly as per Heisenberg's guide then recovery is overwritten anyway. And, you can't flash anything unless your bootloader is unlocked. You would need to reflash TWRP and SuperSU after it first boots.

I would suggest booting it up stock and letting it set up before flashing TWRP and then rooting. And if you do, when you flash TWRP via fastboot, boot right to recovery and flash SuperSU, otherwise TWRP will get overwritten by stock recovery. Rooting stops that.

So you went through that and flashed the wrong Gapps pkg again? I may regret asking but what custom ROM are you flashing? There are really only debloated stock variants right now.

Not again, only flashed wrong gapps once, was trying to flash cm13 and got the gapps from opengapps.org. It's ask good now tho, I'm back to stock thanks to you guys and the skipsoft toolkit! Thanks again!
I should start this off by saying that i have no idea how to root a device and i am now currently aware of how stupid my actions were.
I've searched the forums for about 2 hours now and i've yet to find a solution to this problem which is stressing me out like you wouldn't believe.
about i year ago i tried to root my Moto X Pure edition but i failed miserably so i returned to stock and lived without. This morning i decided i would try to root again but it isn't going so well.
I followed this guide: http://forum.xda-developers.com/moto-x-style/general/root-moto-x-style-xt1572-br-marshmallow-t3259380 And everything worked fine until i noticed that my wifi wasn't working.
I then decided to flash back to the original boot image which i found from this site: http://androiding.how/systemless-root-moto-x-style-marshmallow-mph24-49-18/ But my wifi still refuses to turn back on
By now I'm a bit stressed out and not thinking straight. I then recalled that device encryption can screw with the rooting process so i decided to factory reset (how stupid can i get.)
So now im sitting at the welcome screen and my XT1575 cant find a wifi network so im going to have to restore my device over cellular data.
What do i do!?!?!?!?!!?!?
EDIT: i just realized the first link i posted was for the XT1572. I feel so stupid. how do i restore original functionality to my device?
I have had this issue before but on a Moto X Style (XT1572). You need to flash the modem again through fastboot/ADB. You first need to download the full stock firmware and extract it on a PC. Reboot your phone into bootloader mode and run the following command through command prompt/terminal:
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
You may need to do this twice as it doesn't work always first time. Refer to this post for more information:

I've learned a lot in the past two hours. I did try to reflash the modem multiple times with multiple different files without any success. I don't think the method i was following works for XT1575 specifically.
I am currently back on stock with wifi working. I like the idea of a systemless root, but i couldn't find a method that works for the Pure. So i guess i will continue to run stock until i get a new phone (that might be a while.)

Glad you managed to sort out your WiFi.
If you are on stock ROM but have tried root, it means you already have an unlocked bootloader. You could always try and flash TWRP and then flash a pre-rooted stock ROM from here:
[ROM] Flashable Stock/Rooted X1575 6.0 MPHS24.49-18-4 (May security update)
This will give you what you are after minus the stock recovery. You could then just reflash the stock recovery using fastboot/ADB:
fastboot flash recovery recovery.img

Just download the full stock of the firmware version you flashed through TWRP and then extract and flash the respective version recovery from here:
[FiRMWARE] XT1575 PuRE FiRMWARE aNd STuFF
You should then be completely stock with root.
I tried systemless root on my XT1572 and didn't get on with it. Kept having issues so just went with full root and am happy with my phone as it is; stock 6.0.1 with full root and a few stock apps removed that I don't use/need.

The only app I am aware of without root is Helium. I haven't tried it personally but I think you need to have an app running on your PC and the phone connected to it. I personally use TWRP with Nandroid Manager and Titanium Backup. These both need root though. You could always make a backup through TWRP prior to flashing the pre-rooted ROM, then flash the ROM as always recommended. If you run into issues, just restore the backup through TWRP, then flash the stock recovery back through fastboot/ADB to be backup to your original state.

I think i can answer my own question now. TWRP is a "custom recovery" and after i use TWRP i can flash something over it so that i can be stock. The terminology around these parts is quite confusing
i've gone and ****ed everything up again. I flashed twrp and then tried to install a zip from the first link you provided but my phone refused to unlock
I did a factory reset from within twrp and reinstalled the zip but now my wifi isnt working again.
Is rooting always such a pain in the ass?

When rooting, there is always a risk. I have been flashing phones for over 10 years and it is always a learning experience. Even now i have occasionally done something and thought I've completely mucked up my phone. You just need to make sure you follow exactly what is stated as the procedure and if you run into problems, there is always someone at hand to help in this great forum.
Out of curiosity, did you follow the standard procedure for installing a new ROM? You will lose all data doing the standard procedure but can restore most stuff from your Nandroid backup. The steps I always do is:
1. Make a backup
2. Wipe data, system, dalvik/art and cache partitions
3. Flash your ROM
4. Wipe dalvik/art and cache again
5. Reboot
Click to expand...
Click to collapse
That is the standard recommended procedure for flashing all ROMs in TWRP. I have an EU XT1572 and have successfully used this ROM on my phone. The ROM contains everything you need including the modem. The modem is for the US XT1575 but worked fine on my phone. For sanities sake, I flashed the EU modem after and still had everything working.
Just another point, your phone needs to have been updated to Marshmallow before you can run one of these ROMs. If you are on Lollipop you may run into issues, especially from a radios perspective.
Another thing to point out is that all ROMs are started that you flash at your own risk. Developers will not be held responsible for anything going wrong. As long as you follow the guides and don't flash a ROM for a completely different device, you shouldn't run into any issues and more often then not can bring your phone back to a functional state if you do.

Flash twrp
Make backup
Flash su 2.62-3
Done.
Or...
1. Flash the factory image
2. Flash TWRP
3. Flash this attachment in TWRP, which will force install SuperSU 2.78 SR-1 systemless-ly. I've shared and posted about it before in this thread.
Nothing's changed with the attached zip here, except it has the latest version of SuperSU included as of this post.
