Revert to stock - Xoom General

I am trying to revert my us wifi xoom to stock
I can get in to fastboot
I can flash boot recovery and userdata
However every time I try and flash system it fails with failed to process command 0x20000000
I am currently running a rooted 3.2
Anyone have any ideas?
Thanks
Tim

What's your host OS, I flash my MZ601 (UK3g) via an elevated command prompt (Win7x64) and it works fine here.
I have this little lot in a batch file I run.
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache

I am doing this in Mac OS but I can reboot and try it in windows

OK thanks for the tip the flash went fine in windows

What happens if you are rooted and accept the over the air update? Will it just unroot and return to stock without any problems?

No Os No Recovery & Boot failed

Guys, i need some help. i was messing with my nexus 7. then i tried to start fresh again by re-installing the stock 4.4.4. It's been a while since i flash Stock roms. So i find this tutorial, Erase boot, erase userdata etc. then when i tried to flash the bootloader, it always fail (unknown error). So im stuck with a OS-less Nexus 7 and no recovery. I can go to Fastboot. My device is recognizable through Fastboot devices. My old Rom was 4.4.4 stock. Please help me guys
Hello @vyrus027,
flash the files inside the factory image manually with these commands, it'll do the trick:
fastboot erase boot
fastboot erase recovery
fastboot erase system
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot format userdata
fastboot reboot

OTA upgrade from 7.0 with TWRP installed?

Hello,
So I've been trying to update my XT1265 which is currently on build number NPJS25.93-14-4. I my phone is rooted with TWRP installed. The phone was unlocked through the motorolla site. There's an OTA update that keeps annoying me so I'm trying to update it. If I try the update it updates, then when it reboots it stops in TWRP. (My phone actually always boots into TWRP when it reboots/boots but I'm able to reboot bootloader and get it booted.) I've read that I need to get back to stock recovery to get it to update. I've yet to be able to find a stock recovery that I can fastboot to reinstall.
What do I need to do to get this to update?
Generally, OTA updates require stock recovery, stock system and stock kernel - any modifications to these and the OTA update fails, as you've found (e.g. the TWRP boot issue). By modifications, I mean TWRP, root, even letting TWRP modify the system read/write status.
If you really want to flash OTA updates, then you'd be best served by re-flashing the stock ROM. The following commands in fastboot should preserve your data and roll back your device to an OTA friendly state. However, back up and be aware that this will remove TWRP, any modifications (including custom logos) and restore your system partition to a read-only status.

Extract the correct stock ROM zip to your ADB directory (it's about 2 GB expanded) and flash with the following commands in your ADB terminal:
Code:
[B]fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img[/B]
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash dsp adspso.bin
fastboot flash oem oem.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 system system.img_sparsechunk.4
fastboot flash system system.img_sparsechunk.5
fastboot flash system system.img_sparsechunk.6
fastboot flash system system.img_sparsechunk.7
[B]fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn[/B]
fastboot erase cache
fastboot reboot
Up to you if you choose to flash the steps in bold, as you should be flashing the same firmware onto your device as what you currently have.
Upon rebooting, your device should be back to where it was (though the initial boot might be longer as the cache is re-built) and then you should be okay to take OTA updates.
If you simply want to silence the updater, have a look at this thread (requires root) : https://forum.xda-developers.com/moto-g4-plus/help/how-disable-notification-update-t3459587
As for the TWRP boot issue, you may wish to look at this thread too (though I've not tried this, so be careful) : https://forum.xda-developers.com/moto-g4/help/troubleshooting-twrp-boot-loop-ota-t3714325

Moto G4 only boots in fastboot

Hi,
I have a problem with a Moto G4. I tried to root the device and think I f***** up a bit.
After successfully installing TWRP I tried to install SuperSu using adb sideload and afterwards the device wouldn't boot anymore. Only fastboot and the recovery are still working. If I try to boot the device it just turns off. A factory reset didn't help.
I tried installing a LineageOS but nothing changed. It still boots into fastboot.
Can anybody help?

I forgot to say that I at first didn't install supersu systemless.
After I noticed that the device wouldn't boot anymore I tried installing it again systemless.

Hmm, did you wipe your system and data in TWRP before flashing LineageOS? You do not require root to flash LineageOS, just an unlocked bootloader and a compatible TWRP recovery (taking care to note if you need the 32 bit or 64 bit TWRP recovery for the respective custom ROM).
Also, with rooting on our G4/Plus, if you are on stock Nougat, you must flash a custom kernel (e.g. ElementalX) before you root. You'll otherwise experience the boot failures you're experiencing. Thus, to root on stock Nougat, unlock bootloader, flash/boot TWRP, backup, then flash ElementalX, then flash SuperSU/magisk.
Without knowing the current state of your device, I would suggest re-flashing your device with the stock firmware. Can you remember what stock firmware you had on your device before rooting initially?

Hi, thanks for your reply
Yes, I wiped system data and cache before flashing lineage. I just tried it again and I am still stuck in fastboot.
Unfortunately I don't remember the stock firmware version. Should I just try to flush the custom kernel and supersu afterwards?

Hmm, did you know if the flash of LineageOS reported okay within TWRP? Just out of interest, which TWRP and which build of LineageOS are you flashing (e.g. are you using the 32 bit TWRP or 64 bit TWRP, and are you flashing the 32 or 64 bit Lineage OS)?
That's confusing that even pressing 'start' in fastboot reboots your device rather than booting, even with a custom ROM... What happens if you boot to TWRP and try to reboot via TWRP? Is there a system to boot to?
Without the stock system on your device, there's no point to re-flashing the custom kernel/SuperSU, since you should have LineageOS on your device. Do you have a TWRP backup you could restore before you tried to root? If not, then what's your device model number (and if you can remember it, what software channel you're on, e.g. retus, reteu etc). ?

Yes, everything was ok with the flash.
I am using lineage-14.1-20180516-nightly-athene-signed and twrp-3.2.1-0-athene. I didn't see any options to choose between 32 and 64 bit. (Download pages: https://download.lineageos.org/athene#!name https://eu.dl.twrp.me/athene/)
It doesn't matter how I try to boot (powerbutton, fastboot, recovery) I always directly end up in fastboot.
No I don't have a backup. When I got the device it was resetted so I saw no point in making one :/ It is an XT1622 and it should be reteu.

Okay, so they should both be 32 bit, so no worries there. There do seem to be a few reports of boot issues on the more recent official LineageOS builds https://forum.xda-developers.com/moto-g4-plus/development/rom-cyanogenmod-14-1-t3522101/page280 but I don't know if they are still existing on the build you've flashed.
As it's likely your device has been reset when you flashed LineageOS (I don't know if there are still files on your internal storage, which you can view in TWRP, so back up if you do have files), you may wish to look into a stock firmware flash. Here's the April 2018 NPJS25.93-14-18 firmware, which appears to be the build released to EU devices: https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138 You do not have to re-lock your bootloader if you don't wish to - if you wish to leave your bootloader unlocked, then flash the stock firmware via fastboot with the following flashing commands:
Code:
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img

fastboot flash system system.img_sparsechunk.5
fastboot flash system system.img_sparsechunk.6

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
Flashing these files via ADB should put a fresh copy of the latest firmware onto your device, which should then boot. If it does boot, then you can proceed with rooting (flash TWRP, then back up, then flash ElementalX or vegito, then flash SuperSU or magisk).

Thanks for the help!
I can boot the stock rom and I have root access. However if I start or shut down the device it goes to fastboot. From there I can boot or shut down the device and everything seems to work Do you know how I can boot directly without fastboot?

Hmm, try booting back to the bootloader, attach your device to your computer, then open ADB. In ADB, type 'fastboot oem fb_mode_clear' without the quotes. Press enter to submit, then reboot and see if your device boots to system rather than to fastboot.
This command should clear fastboot mode (though useful when flashing).

Nexus Player Rom help

Hi im having problems here with my nexus player
i purchased and used this since 3year with custom AOSP android lollirock that i found on this forum how to install in the begining when i purchased it now since there are newer version of android and app stop working correctly on it i wanna return to the stock rom
what it did is after booting into fastboot and running those command using google official rom
fastboot erase boot
fastboot erase recovery
fastboot erase system
fastboot erase cache
fastboot flash bootloader (bootloader filename)
fastboot reboot-bootloader
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash cache (there were no cache.img in the google official rom package so i leave it like this)
fastboot reboot
my nexus bootloader is in UNlocked state, i remeber unlocked it the first time i flash the original rom to install the lollirock one
the device rebooted and now im stuck in the bootloop of circle turning in the screen
i did the exact samething trying to install a older version of the rom (after i read on the internet that the 8.00 was sending people who never messed around with fastboot and just using OTA to update into this samebootloop)
i got the same exact problem using an older version of the google official rom 7.1.2 i try i think
then i tried to reinstall AOSP custom 7.1 of android that i found on the forum of zulu99 he tell to
fastboot flash boot boot.img
fastboot flash system system.img
fastboot -w (and i noticed that when i run this fastboot return me and error saying that the file is missing (cannot generate image for userdata)
anyone know what i can do from here ?
im able to get into fastboot no problem holding the button under the device before i plugged in the power cord
im pretty a beginner using ADB and flashing android roms so i have no clue what im missing here but i guess its something due to the fact that ivd run fastboot erase cache.img in the begining !?!?
Please any help would be greatly appreciated
I always used the nexus root tool kit for everything.

2019 pro stuck in boot loop

Got this working with Lineage ok but decided to go back to stock. I downloaded the stock recovery rom from NV and set everything up. Inside the recovery bundle is a bat file. Usually I would flash all files manually but this time I used the bat file. It manged the first 3 or 4 commands then came up with error. The box is now stuck in a boot loop and I am unable to access over adb.
Can anyone please suggest a way around this.
Thanks
Here is the bat file
fastboot flash staging blob
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash vendor vendor.img
fastboot flash dtb mdarcy.dtb.img
fastboot flash vbmeta vbmeta.img
fastboot oem lock (optional step: required for certain functionality)
fastboot reboot
EDIT:
Eventually managed to flash lineage zip again. Used USB keyboard to access recovery
may i ask, what kind of keyboard did u use?
thanks in advance
