4 ways to fix TWRP recovery no OS installed error.

[@farheenkhanum4971]

The No OS installed message made me wonder if it's time to shell out a new phone, or wait for weeks till the service center can fix the device, you're an absolute lifesaver. Thank you!

[@jenna117]

No OS Installed means you deleted your Rom or Custom Rom to fix it you need a Stock Rom or Custom Rom depends on what file

[@bayl2329]

Thank you mate, absolutely freaked out when I realized i couldnt put my firmware files under internal stoage before reformatting the phone entirely! Luckily it had an SD card reader, phew!

[@Rootjunkycom]

[@NotPracticingLawdotinfo]

Excellent... video....so where you been hiding these to many moons ago, when I dished my SNote4.....at least 2 times with Not enough Wiping ..... LOL! This is really great "How Tos" for us old people, who don't care for "Stock" .. nothing, unless it is "stock cars," but NO need no "stock phones!" Putting on new TWRP and than lineageOS 17 on Note 4! Was running "Bean Stalk" for to long, and need a break, but NOT the phone... just the ROM! LOL! Thank you!

nice cool to see someone still rocking a Note 4 :-)

@rootjunky could you do an updated video tutorial on how to write a ducky script on the USB Rubber Ducky and how to write scripts for the Bash Bunny USB. I know that is not something you usually post video tutorials about but I've been watching your android tutorials since Lollipop and you make them very easy to understand.

So what causes the "RED ERROR 7" . . . .while..... installing any custom ROM via TWRP? After wipping the 1. cache 2. dalvik cache .... this is what TWRP states....... "What should I wipe in TWRP? If you are switching ROMs (changing from one ROM to a completely different one) then you should perform a factory reset." Since I have that OS backed up, and want to install ASOP / LineageOS 17... what should I WIPE to get rid of the "RED ERROR?"

This looked promising but my nord n10 Twrp will not let me mount the sd card or the otg, and the phone does not show up in windows,so I cannot do anything. And my version of twrp is unofficial so I needed to connect a usb mouse via adapter to even get to select options. adb and fastboot work. I have no idea how to even get this repaired. If you have any thoughts, please let me know. This all came about after I did a system upgrade to Oxygen 11.0.1, lost root, and reflashed twrp. Thanks for your work!

you should flash the phone in odin mode with odin software and get it back to stock firmware then you can hack it again with twrp and flash a different rom. this will get it working again.

[@ClintonGlasener-jx3yw]

Heya Rootjunky! I know it's a long shot that you'll see this; but if not maybe someone else could help. I'm trying to determine if accessing EDL mode on a Motorola might enable me to root a device or unlock a bootloader that would otherwise normally be unable to be unlocked (Verizon/moto one 5G Ace UW) OR, at least if blankflash might help me in assuring I wipe the phone from any malware/spyware currently on it. I can use LMSA all day long but it's pointless; after first boot there is a plethora of apps, especially Verizon bloat apps, that have exploited permissions or whatever and apps that are clearly not legitimate and no matter how many times I flash the firmware I cannot get an actual clean OS install. If I try using fastboot, I get a lot of header sparse errors when it gets to the super chunks. So I assume the same is happening with LMSA and I thought well maybe I could get into blankflash mode and run one of the blankflashes from lolinet, but would this prove to be a practical use of blankflash or is blankflash for something entirely different and if so, what? (In very basic terms more or less)

[@Rootjunkycom]

The blank flash files just restore the bootloader if it gets corrupted. basically it will bring back the bootloader and get it working again so that you can flash the firmware with fastboot or LMSA tool. The bloat apps you are talking about with that device are from the manufacturer and can not be removed unless you have root access to the device or back in the day you could flash the oem config file from a stock firmware and it would remove it. But this method has been locked for many years now. EDL mode is normally a MediaTec chip mode and you can do a lot from that mode but since you have a verizon devices I am pretty sure it is a qualcomm chipset and not mediatek. Basically unless you can unlock the bootloader with Motorolas official method then you are out of luck.

sounds like there is an incompatibility. you should head to XDA for support in the forums. on newer phones you have to be on the latest OEM ROM before flashing a custom ROM. Not all ROMS will work with all devices.
