no recovery! please help? - OnePlus 2 Q&A, Help & Troubleshooting

So, I installed the new ground zero ROM, validus 8.1, but it has wiped my recovery and only stock android 6.0.1 recovery. I have flashed twrp though adb with no luck. Any advice?

I have fixed my issue if anyone is interested.
Validus was the first ROM ever to have wiped my recovery back to stock Android not even OnePlus recovery. I had to fastboot OEM unlock bootloader again and flash two again via fastboot. Almost a brick!

Lack of recovery

Hey guys, I'm a longtime XDA browser but hardly ever post. I have the MXPE rooted with the newest TWRP build and has been running great since I got it. last night flashed the Deodexed 6.0 build from AICPs 5.1.1. I had some issues with the SD card being mounted as internal storage and erasing something so I tried to flash back to stock as my nandroids weren't seen as usable.
Long story short when I flashed back to stock, the recovery would never take. I've flashed the stock recovery and twrp to no avail. For some reason it wont actually stick. Everything else is back to stock but that. When I used the win toolkit and tried to flash twrp again it said something about the folder locations so I'm wondering if I messed something in the partitions.
Question is, have you guys ran into this issue or have any insight on where to go from here? I've looked around but I couldn't find a post that the same as this issue. As a side note, I can get into the bootloader just fine.
I appreciate any info that someone can provide.
Flash twrp. Reboot back to recovery from recovery. Reboot system.
Hopefully it's that easy. Stock os flashes stock recovery on boot. Rebooting recovery from recovery prevents that from happening.
From TWRP:
"Note many devices will replace your custom recovery automatically during first boot.... Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install."

Thanks for the info ffejy462. What happens when I try to flash TWRP and it doesnt stick? I know for a fact that I can boot into it temporarily with fastboot boot and the recovery file. Should I just flash it from there?

I'm sorry I didn't see this sooner. Flash recovery with fastboot. Boot into recovery. From reboot menu in recovery, select reboot recovery. Twrp will patch so recovery isn't lost again.

That did it. thanks alot ffejy462!

One Plus two not Loading Recovery Mode (stuck on Logo)

Hi, I need help in installing Recovery.
I unlocked the bootloader, installed TWRP and then CyanogenMod 13 ROM.
After this, Oxygen Os 3 got released. I downloaded the zip file and flashed through TWRP.
Oxygen OS got installed but after this, I couldn't go back in TWRP recovery.
I tried everything. I use "fastboot flash recovery twrp.img"
everything works
but when I boot in recovery, phone gets stuck on the LOGO and nothing happens.
Is there any way to solve this issue.
Almost the same for me.
When I flash oOS 3.0.2, unable to reboot using Grarak'sTWRP or TWRP-3.0.2-1.
Always stuck on boot logo without animation.
I reverted to old TWRP and oOS 2.2.1

Try to install OOS recovery or Hybrid recovery.
Nobody ever learns or reads nowadays....
Read up on bootloader versions on Oneplus 2 and you will find the explanation perfectly understandable.
Thank You So much for your help. Finally it worked but I lost my data! Anyways, no issues.
Can you give us the way you fixed your problem .
Thanks

Stuck while flashing Rom zip [solved]

I officially upgraded to 3.0.2, unlocked and rooted my phone.
It was fine for the first few times I flashed multiple ROMs. But ever since I flashed Exodus, I keep having issues switching to different ROM.
A week ago, I flashed "Switch to OOS3_H2OSMMv7" zip and was able to flash Resurrection Remix, but today when I tried switching to CM13 or PA it gets stuck at flashing the ROM zip. I tried flashing the firmware zip again and flash the ROM, but to no avail. It won't flash any ROMs now, just stuck at recovery while flashing the zip.
I have a working fastboot and recovery mode though, so I'm trying to avoid flashing the entire factory image but that seems to be only option left. Does anyone have any clue as to why this is happening and how I can fix it?
Edit: Resurrection Remix gets installed fine, CM13 and PA still giving me issues.
Edit: I downloaded the latest version of CM13 and it works. Earlier I was using June 30 build which seems to have issues with the new firmware. I'll try out the new PA build to see if it fixes that too.
What error does your recovery gives?
Do you have Data Backup?
Can you access ADB while in Recovery?

It does not show any error as it just looping while installing the zip. I have to force shut down the phone to exit it.
Yes, I have backed up all my data
Yes, I am able to access my phone in both ADB and in fastboot modes.
After flashing Custom ROM, Wipe data, cache, d-cache and then reboot.
If still doesnt work try flashing another custom ROM. You can use adb-sideload to flash another zip in recovery mod.

Soft-Bricked, no access to recovery.... HELP!

Hey everyone.
I'm really hoping someone can help me. I just got my Redmi 2 Prime today, and before even properly setting it up I had rooted it. It wasn't long before I decided to try a different ROM. I decided on Resurrection Remix and TWRP recovery, both of which I flashed an ran flawlessly. RR booted up, everything was great.
I then tried flashing SuperSU again, after installing RR. Flashing the .zip file resulted in a boot loop, with no access to recovery, only fastboot.
What I've tried (with no success):
- Re-flashing TWRP (through Fastboot).
- Flashing CWM instead (through Fastboot).
- Flashing stock recovery (through Fastboot).
None of these have proven successful..... Can anyone give any advice on how to get out of this mess? I hardly feel up for having to take my phone into a shop without even having had it for 24 hours.....
TIA!
Fastboot flash Redmi 2 ROM. Download ROM file from MIUI forums and read the instructions there. Go to this link http://en.miui.com/a-234.html
i dont know if this comes at the right time,since fastboot is accesbile ,boot into fastboot, and flash recovery into boot(this may sound foolish but you can do it)
fastboot flash boot recovery_twrp.img
reboot,you will be taken into twrp
you can take a backup here,
now wipe all and flash the ROM.zip
anfd it should all work fine
I had the same problem when I switched from MIUI 8 4.4Kitkat to CM13 6.0
But I was able to solve it without fastboot.
RessurectionRemix and most roms esepecially CM based have "built-in" superSU manager.You just have simply to re-enable it on the developer settings.No need to flash supersu.zip,it would just make things worse.Download Flashify to boot in TWRP manually since flashing different ROMs will temporarily remove the TWRP(doing the button combination wouldn't boot into recovery,instead bootloop like you mentioned).
Then I was able to perform a restore on stock MIUI 8.
You have to download Flashify in order to manually force the phone to boot in recovery mode,since doing to volume up+power wouldn't let you.
I don't know if this is because my TWRP version only supports KitKat....or switching from 4.4-6.0 is a big gap.
Thanks for the responses!
I ended up solving the issue, though there wasn't really an issue to begin with. Turns out the button combination to enter recovery is different than stock (both volume buttons and power), though I did re-flash to the latest version of TWRP.
I'm now running Resurrection Remix without flaws!
But yeah, I realize now that CM based ROMs have a baked-in SU manager, it was foolish of me to flash the file without doing proper reading up beforehand!

Moto X Style bootloop on custom ROMS

Hey XDA,
I've just unlocked my bootloader and flashed TWRP 3.1.1. I was on the stock Nougat OTA. I wanted to install LineageOS 14.1, but I get a bootloop on the latest nightly. Process was factory reset/wipe -> flash ROM, Gapps, SU -> wipe dalvik, reboot I figured that maybe it was an issue with the nightly, so I installed Resurrection Remix and got the same issue.
Stuck on boot animation, occasionally a very slight vibration.
Does anyone have an idea of what this is?

Search a little... most custom ROMs do not work on a device that was updated to Nougat due to differences in radio firmware and partitioning. Try a newer Nougat custom ROM like Dirty Unicorns, and only flash ROM and appropriate Gapps, after boot is verified try flashing root with the latest SuperSU (2.82) or Magisk (14.0) only.
And clean flash... wipe everything but internal/external storage, then flash.

I don't know any custom working with Nougat baseband.
Before custom N you should downgrade it.
Download last MM for your model, unzip, and flash:
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
Reboot to twrp, adv.wipe - everything(except sd card) and flash any custom N you want.
