Can I do that? My device won't boot into recovery, despite flashing it through fastboot several times. Also tried "fastboot boot twrp.img" and it doesn't boot. Can I flash original OxygenOS or any other rom through fastboot? If so, how?
Also my device cannot be seen @"adb devices", I believe usb debugging is off, any way I can turn it on using fastboot? Googled for a while and couldn't find any information.
Just google "Mega Unbrick Guide" or search here !
Thanks for the suggestion, I did follow that process successfully but the phone is still stuck in a bootloop. The bootloader locked in the process as well and now I cannot flash any recovery through fastboot. The phone will get into recovery though but trying to sideload anything will result in a "protocol fault(no status)" error.
As a sidenote, the internal storage seems "faulty" to say the least now. It is not recognized at any time as MTP device but rather shows 3 unformated partitions of 1.00MBs, 155MBs and 2.5GB respectively. Moreover trying to "Install from Local" @recovery menu renders no response, just a short vibration, sometimes.
Anyone else encountered this problem? Is there any chance it is a hardware problem afterall? I'm really clueless right now.

I have searched a lot on google and xda and havn't found an answer to my issue. Either I'm searching for the wrong thing or I have a very unique problem.
My basic problem is on two Nabi 2's I can't access the bootloader in order to be able to fastboot TWRP (or any other recovery). It just perpetually hangs.
Both tablets boot just fine. Both tablets are on 1.9.37. Both tablets can be factory wiped via the stock recovery.
Both tablets were rooted via TWRP 2.3.3.0 a few years ago in order to install gapps. I wanted to be able to upgrade the tablets to JB when it came out so I used Nabilablite to "return to stock". I followed all of the prompts and it appeared as though everything worked as desired. I downloaded the OTA update told it to install and never looked at the version again...I just assumed it installed. Handed the tablets back to the kids and everyone was happy. Apparently all I did was flash the stock recovery because they are still rooted and have gapps after several factory resets.
Now (a year later) I have realized I was a dufas and didn't actually effect the change I wanted.
If I hold Vol+ & Pwr buttons it loads to the recovery/boot menu with "boot normally" "fastboot protocol" "recovery kernal" and "forced recovery". If I boot normal, the tablet works fine but I can't update via OTA.
If I choose fastboot protocol it just hangs...for ever...HOW DO I FIX THIS!?!?!
If I choose recovery kernal it loads the stock recovery but still wont install any update OTA or otherwise, even from the sd card.
If I choose forced recovery nothing happens, it also appears to just hang.
If I hold Vol- & Pwr button the nabi logo flashes then the device turns off.
If I hold Vol+ & Vol- & Pwr buttons it appears to be the same as just Vol+ & Pwr.
With the tablet on and fully booted I can see it via ADB. I tried using the adb restart bootloader. The tablet reboots but then just hangs never actually loading the boot loader...
I found http://forum.xda-developers.com/showthread.php?t=2587543. But aicjofs mentions seeing a bootloader issue once before.
Usually when it hangs at the Nabi logo it means you don't have the USB cable plugged in or that the fastboot driver is not installed.(Check device manager and see if fastboot driver is installed/no exclimation point). If that's not the issue then it's the bootloader which I have only seen one person have that issue. Depending on which OTA's you have ran there was an update to a Jellybean bootloader so it's possible. That can be fixed with nvflash or placing the bootloader blob in the staging partition.
Also you can always get recovery back without fastboot in Android by dd'ing the recovery over.
For example if the recovery image is on the internal SD
dd if=/data/media/recovery.img of=/dev/block/platform/sdhci-tegra.3/by-name/SOS
Click to expand...
Click to collapse
I have NO idea what dd'ing the recover over is...
Thank you for any help fixing this.
P.S. I have a 3rd tablet that I also used TWRP 2.3.3.0 on to root and install gapps with. I did NOT use nabilablite on that tablet to return to stock. Yesturday I used fastboot to flash TWRP 2.6(something) to flash a JB OTA update which worked fine. It was also able to download and install every other OTA update all the way to the most recent KK with no problems...

EDIT: OOOPPS. I didn't see this was in the XDA Assist section. I'm not suppose to answer questions(I was just searching for Nabi questions and didn't notice this was XDA assist), dedicated XDAers just point you in the right direction in this section. Please ask the question again in the Nabi2 section and I'l come help you. http://forum.xda-developers.com/nabi-2
This might help answer some questions http://forum.xda-developers.com/nabi-2/general/nabi-information-t3229119
If it just hangs at fastboot protocol then the USB connection isn't good or fastboot driver isn't installed most of the time. Can you verify fastboot shows up in device manager?(I know the 3rd tabet worked OK) .
Nabilabite doesn't do anything that should change the bootloader, and fastboot should still work as it did before.
dd'ing recovery over means that you use the root access you have in Android to flash the recovery partition instead of using fastboot. IT's just another way of getting the TWRP recovery on the tablet.
The stock recovery won't install the OTA because when you added Gapps it changed some fies and the OTA sees those files as invalid and will fail.
Forced recovery always looks blank screen. It's waiting for you to give it a bootloader to run(beyond the scope here).
You should be able to get back on track once you have TWRP loaded. It's one of 3 things. Bad USB connection, fastboot driver not installed right, bootloader damage. Check the first 2 issues despite the fact the 3rd tablet had no such problems.
One of the XDA smart guys fixed my error of posting this in the wrong section.
I'm running Windows 7 Ultimate and have installed and re-installed the drivers several times. When the tablet's are fully booted ADB has a good connection and sucessfully sends the command to reboot. So I don't believe there is a driver or USB cable error...
When the tablets hang on the fastboot protocol my computer makes the usb connecting noise but fails to install the drivers...
When I hit forced recovery I hear the unrecognized USB device sound...
These two things make me think I don't have the proper drivers installed...but I don't understand how the driver's work when the tablet is booted but not when trying to access the boot loader.
It appears as though I'm going to have to try the dd method if you are able to point me in that direction please.
EDIT: Now I'm thinking I really DON'T have the fastboot drivers installed. I just plugged the 2nd tablet that hands on the fastboot menu and fastboot failed. I also booted the tablet completly, the adb driver's installed correctly but the fastboot driver's did not...I have installed the 64 bit driver's included with nabilablite. I can't find any actual other downloads. The 15 second ADB installer didn't change anything...

Hi all, this is my last hope at the moment. Any input would be highly thanked.
I own an ASUS Padfone 2 (KOT49H.WW_Padfone-11.8.4.23-20141028), stock firmware, that I managed to get soft-bricked, as I read they call it.
Phone is unrooted, ran KitKat, and I really don't know much more about it, I'm not really an expert unfortunately... No custom ROM or any of those pro stuff.
Scenario:
Every single app crashed upon opening, performed a reboot, phone got stuck into infinite boot-loop, at the company logo in the beginning.
What can the phone do and what I've done so far (all of which have been found through internet):
I can enter into recovery mode.
Did a factory reset and wiped cache partition before the following.
I entered what the phone calls "CSC mode", that other sources call "fastboot mode".
Followed this guide http://forum.xda-developers.com/showthread.php?t=2256977 , installed drivers, entered into the proper directory on CMD, and typed "fastboot boot recovery.img", but CMD says "OKAY" and all, but gets stuck at "booting...", even after like 15 minutes.
Then, for whatever reason I saw on the internet, I tried the command "fastboot oem unlock" that also didn't finish anything either in CMD or (seemingly) on the phone.
Then, I tried following this guide in CSC mode (even though I don't have the invalid kernel error) http://www.modaco.com/forums/topic/365818-padfone-2-invalid-kernel/#comment-2191432 , but also didn't get any further than CMD stuck at "booting..." for forever.
I suspect it could be possible to do some of those booting magic, but I have no clue how it works and how my problem inside the problem could be solved...
Thank you so much in advance.
(Please beware that I don't understand what the words bootloader, fastboot, flash or ROM mean. I'm a mere mortal.)
I've searched around but haven't found anything on this. I want to root my phone to get more out of it and all, but It's not going so well.
My phone is a Huawei Honor 7 running Android 6.0, I'm using stock since I bricked my phone (I backed up anything important which were some apps and my contacts and such), so I have that which I can import.
I've followed different tutorials with no success in getting TWRP onto my phone, I got it unlocked but I can't get any further.
This is what I've tried for it:
Boot phone into Fastboot and have it connected wia USB to computer.
Checked if it shows up in "fastboot devices", which it does.
Did "fastboot flash recovery TWRP.img", which it says went OKAY, but then when after rebooting it, and getting it into recovery mode, it just boots into the default Huawei eRecovery, and not TWRP.
I've tried different TWRP images, some who said it were for the Honor7 as well, but with no luck, it just won't boot into it.
I hope that's all the needed information, if need anything else just ask.

If you want to get into recovery you have to unplug your phone from PC. You can use "ADB reboot recovery" command if you're connected and running system.

+1 the phone must not be connected to the pc when you try to reboot in recovery mode
Also you can use the MultiTool to install Twrp and reboiot to recovery from this tool
Thanks a lot guys! I'm able to boot into TWRP now.
Now I only got to fix my SuperSU problem, it makes me stuck where it says honor, which is loading screen really.
Tried different versions of the BETA-SuperSU (using the betas because got one from tutorai ladn read that they support Android 6.0), but as said simply stuck and don't know if it actually rooted my phone.
The facts:
-I'm an idiot and I dun ****ed up.
-I'm a fool to believe I could power my way through learning how to flash roms and unlock the bootloader unofficially.
About the Device:
1: Kenzo.
2: I can access Fastboot (PWR +Volume down)
3: When I try to boot the device, the Mi logo is visible for 3 seconds, disappears, reappears again and then then the phone turns off.
3.a: When connected to my computer via the official cable, the screen remains pure black and the red light blinks repeatedly, as if in EDL. In device manager, the phone reads as "Qualcomm HS-USB Diagnostics 900E (COM10)
4:XiaoMIFlash and MiFlash tool both do not detect the phone when I hit refresh (which is why I can't seem to fix it)
5: Putting the device in Fastboot and attempting to send any command through CMD/ADB results in either nothing happening, or <waiting for device> showing up, and then nothing else happens. (This used to work before)
6: I don't believe I can access recovery (PWR+Volume UP)
7: Could not unlock bootloader officially due to getting stuck at 50% with "Not connected to Mi Phone" error.
I ****ed up. Bad. I really need help. I tried following many tutorials, but all of them assume that the device can be detected by MiFlash, but mine can't.
Please, I desperately need help. I'm new to android and if I can somehow manage to get this fixed, I'm keeping MIUI, to hell with custom roms, as long as it works.
Please help, I'm at my wit's end.
PS: If the only possible way to fix it is test point method, please post the name of all tools I need, so I can go and buy them.
PSS: Device bricked after attempting unofficial unlock. I never got to the "OEM unlock" part, it bricked before that.
PSSS: Before bricking, I was using China Dev rom. As to try and avoid bricking the device, I switched using miflash to kenzo_global_images_V8.0.5.0.LHOMIDG_20160805.0000.29_5.1_global.
Then, following the unofficial unlock tutorial, I tried flashing the same rom with the modified prog_emmc_firehose_8976_ddr, and it bricked there.

Have your phone boot into fastboot. Connect your phone, run adb and check if it receives commands by using : "fastboot devices". If it returns a value then your phone is detected on your computer. Next, download this file : https://www.androidfilehost.com/?fid=24591000424940129
Now, extract the zip file and open Reboot.bat . This will open cmd and press the enter key.
Your phone is now booted into EDL mode. Now MiFlash should detect your phone and you can flash a stock image from the Miui forum. Probably best to to flash stable ROM (fastboot ROM).

So far, I've managed to successfully boot into EDL by unplugging the battery and USB. Now, I just need to figure out why Miflash is giving me a "System can't find path specified"

Read this thread : http://en.miui.com/thread-91415-1-1.html
Make sure that you've disabled driver verification signature, your path to the image folder does not contain any spaces, and also the flash all data except data and storage option.
Hi,
my Note 5 (which is standard with latest software updates) hangs on the Mi screen when starts up. I can get it into FASTBOOT mode.
And when I connect to PC/Windows 10 and go through adb and enter this:
fastboot devices
gives this result:
fcef713c0904
But I'm not sure what to do now? I guess I need to flash some sort of recovery but not being super tech savvy I'm a bit nervous.
thanks Phillip

Edit: fastboot is recognicing your device, as far I understood what you mean you tried to unroot it and gave you bootloop, flash the boot image that you are using lastly through fastboot and see what happens

Hi,
thanks for your reply.
I wasn't trying to do anything with my phone (root or unroot) when it started this behaviour so I don't have a boot image to flash? And my phone doesn't have 'usb debugging enabled' but because it won't turn on I can't enable it.
So i need to do 'fastboot flash recovery twrp.img' but when I do this it says cannot load twrp.img no such file or directory.
Aaaaaah!
thanks, Phil

Then try first going to recovery stock manually and wipe data and try to boot.
There are many users reporting this kind of issues along the time (updating firmware, charging all the night, etc) so the best is enabling USB debugging if something goes wrong you´ll have more options to save your device.
I guess you have your bootloader locked and also for this reason you can no longer use fastboot mode to flash some file.
If the first doesn´t result then your last resource would be to flash a rom through test point method (if you have Redmi 5 Plus-Vince)
