Same here, I ended up with the device having no OS installed and I can't flash through fastboot. When using "fastboot flash boot boot.img" I recevice following:
sending 'boot' (8741 KB)...
OKAY [ 0.607s]
writing 'boot'...
(bootloader) Please flash boot_sign.img
FAILED (remote: check_sign_key fail: no allow update kernel)
finished. total time: 0.943s
Why is this happening?
I also tried "Tethered Temporary CWM / TWRP Recovery Session" and in that menu I tried install zip file (UL-K016-WW-4.2.2.0-user) but receive following output:
Checking BOM token
BOM flashing failed
return code 0E:Error in /external_sd/MOFD_SDUPDATE.zip (=UL-K016-WW-4.2.2.0-user; just renamed it because I read that in some thread)
My device is from China and I am trying to use a WW version...
I would appreciate any help, thanks in advance!

Hi, I'm currently downloading the needed files which are listed in the thread that you have sent me. Also I've posted a reply to that post (its #111) - do you know if the raw file for FE380CG is suitable for my device, which is FE8030CXG (as I said its from China, maybe that is important to note...) In the list of raw files that are uploaded in that thread the FE380CG is the closest to my model.

Okay, i'll be waiting.

Guys, i've found this on an english forum:
To unlock the boot loader on your Asus Fonepad 8 Fe380cg you need to have the ADT with all the packages installed and configured. Download ADT with all the packages from this link : http://developer.android.com/sdk/index.html
Later once the configuration is done properly then you can connect your device and enable USB Debugging under the options.
1. Download Modaco Superboot file for Asus Fonepad 8 Fe380cg from this link :
http://downloadsafe.org/file/0YgX7 , and save them to your computer.
Tutorial Video : Easy Way To Download file = http://how-to-root.com/10
2. Once downloaded, extract it by right clicking and extract all.
3. On your device, click on Settings > Developer Options > Turn USB Debugging On.
4. Plug the device in to your computer via USB cable.
5. Open the superboot folder that we just extracted (until you see the folder with fastboot-windows inside it), then hold the shift key down on your computer and right click any blank area.
6. Now, select open command window here.
7. In the command prompt, type the following with hitting enter at the end of each line.
adb-windows reboot bootloader (and wait for the device to reboot) fastboot-windows oem unlock *If it gets stuck at waiting for device here, download and install PDANet on your computer, once installed, unplug then plug the device back in and see if that fixes it.
Once it runs the device should display a screen asking you if you are sure. Click yes using the volume buttons. The device will go back to the bootloader screen but say unlocked at the bottom.

Need help installing recovery on XT1526, it's just not working, tried all the methods

EDIT: ALSO, use usb 2.0 ports to flash stuff, usb 3.0 is not working 100 percent yet.
EDIT, 14 Mar 2016: Kingroot got me to root and now I have twrp installed, http://www.kingroot.net/ .
I have a Sprint prepaid Moto E 2015 LTE, XT1526. I did the motorola bootloader unlock, that went fine.
The phone works and is activated on RingPlus, when it boots, I get the Red Warning, Bootloader unlocked, when normally booting.
When I try to flash a recovery to the phone (all that I could find here on XDA), I get this response:
S:\Phones\Moto_E-2015-2ndGen-XT1526\adb-and-fastboot>fastboot devices
TA0XXXXXXX fastboot (edited to take out SN)

finished. total time: 0.015s
S:\Phones\Moto_E-2015-2ndGen-XT1526\adb-and-fastboot>adb kill-server
I've tried everything, and am providing as much info as I can, in case anyone seeing something that is 'new' or 'different' about my phone.
Double check and be sure you're attempting to flash the TWRP for the Moto E 2015 LTE "Surnia", not "Otus" (which is the Moto E 2015 3G). iirc, I used Squid's TWRP from here: http://forum.xda-developers.com/moto-e-2015/development/twrp-squid-twrp-recovery-moto-e-lte-t3137649 . If 3.0.0 doesn't work, try 2.8.7.
You should also try changing USB ports. I ran into a similar issue where I wasn't able to flash things when I plug into my most often used USB port. I suspect that the contacts got worn from how often I used it, so I tried another USB port and it worked fine.
I have done same procedure as yours and meet same problem yesterday.
I flashed twrp recovery with following command,
fastboot boot recovery.img
instead of
fastboot flash recovery recovery.img
here are the post which I followed.

I know that, does not help. I've tried that recovery, one from cyanogenmod also, the recovery img is not the problem. Thanks anyway.
go to phone options and turn on USB debugging and when you go to flash it..
- turn off phone.
- hold volume down and power to get to boot loader screen..
Leave it there and connect to PC.
It should be showing you the bootloader screen.. you know what that is right ?
Then open "Minimal ADB and Fastboot" install folder..
Right click empty folder space while holding shift key down..
Select open cmd window here..
type in either,
fastboot devices
or
mfastboot devices
and make sure it says your device is listed
then paste into cmd window..
mfastboot flash recovery recovery.img
make sure your new recovery file has that name and is copied to that fastboot folder.
that should be it..

Can a DEV please help ? If I need to go back to stock I'll be glad to do it and then unlock the bootloader again, however, I've posted in two diff forums trying to get someone to tell me the correct SPRINT img to bring back to stock, no answers.
XT1526_SURNIA_USC_5.0.2_LXI22.50-29.1_cid9_subsidy-DEFAULT_CFC.xml
XT1526_SURNIA_REPW_5.0.2_LXI22.50-56-1.1_cid6_subsidy-REPUB_CFC.xml
XT1526_SURNIA_BOOST_5.0.2_LXI22.50-14.8_cid9_subsidy-DEFAULT_CFC.xml
I think it's the boost, but it doesn't have the SPRINT label on it, like my phone.
You just said,
"Can a DEV please help ? If I need to go back to stock I'll be glad to do it and then unlock the bootloader again"
So why would you say that ?
Did you relock your bootloader ?
Maybe that is why you are having a problem ?
I never have relocked mine eh..
And i have had no problem flashing TWRP from Squid.. all his various updates overwriting the old one.
I have flashed a bunch of stock retail recoveries too and all of those worked fine too.
I am curious did you try and load recovery after to see if it actually changed or not ?
EDIT:
Can i ask you exactly what Custom Recovery you are trying to install ?
And did you verify the MD5 hash ?
I always do *if it's available..

I've done all those things and tried to post as much info in my OP. Is there a Dev that can help me?
I've now tried to go back to stock in an effort to unlock this biatch using XT1526_SURNIA_BOOST_5.0.2_LXI22.50-14.8_cid9_subsidy-DEFAULT_CFC.xml, and it wont let me do that either. It's not letting me write to the GPT partition. This leads me to believe my phone is NOT unlocked, even though the bootloader shows UNLOCKED BOOTLOADER. Anyone know an answer?
I noticed something a while back when I attempted to flash recovery on a different phone (nexus 6) but failed. I tried a bunch of stuff to no avail. The solution was to simply get a new set of platform tools because mine was too old. Doesn't hurt to try.

Thank you for trying. I just found a post, (and now I can't find it), but the guy went through what I did, and then he used KingRoot, http://www.kingroot.net/ , and it worked.
So, I tried it too, and magic, it worked. I now have root and TWRP installed.
I could have sworn I tried KingRoot, but it must have been on another phone I had.
Are you sure your recovery file is called recovery.img and not twrp.xxx.img? If not you need to rename it
Another problem I had, I was using a USB 3.0 port on my computer. This is a not the way. Using a USB 2.0 port works on flashing stuff.
Hi faheyd, I also have XT1526 on android 5.0.2, but kingroot fails. I was told not to update OS to keep it working in India.
Doess ur phone run on 5.1?
Does USB debugging needs to be activated?

Search root for Archos Diamond 2 Plus

Hi !
I desesperatly seeking a root process for the Archos Diamond 2 Plus.
I can not find it by google.
As it looks like the P9000 of Elephone, I wondered if it was possible to use its recovery.img and supersu 1 and 2.
An idea ? A link for tutorial or for the stock rom (If root process failed) ?
Please ?
ok, no response.
I have tested with unlocked bootloader procedure but :
- i type adb reboot bootloader
- fastboot oem unlock
An normaly we confirm unlock with vol+ . But with archos diamond 2 plus, wol + is not active. There is no reaction at this moment.
So, if not unlocked bootloder, no flashing..
An idea ?

You can boot into fastboot, which is good, in fastboot, type fastboot oem startftm. It will give you an error in the command line but what this allows you to do, is push files into partitions that are mounted R/W, that is of course, if this actually works for your device since every device is different.
Report results!
So after typed fastboot oem startftm i have the message "FAILED (remote: unknown command)"
And after to trying to put img file in boot , i have this : 'FAILED (remote: download for partition 'boot' is not allowed)"

Well, since the device is running mtk, try this. Flash the superuser binary and report, also, I am NOT responsible for anything, YOU are making these changes.
ok tested, but don't work with marshmallow. MTK Droid tools is incompatible with V6

BV6000s : unable to install TWRP

Hey guys, I do not think this is a re-post of the other TWRP problems on Blackview 6000s. I have tried to install TWRP on my device many times. When I reboot into the custom recovery, a android with a danger sign appears. Instead of the TWRP screen. So what is the problem? (Android Noob here, please don't throw big developer words ).
Have tried
1. Changing USB ports / Using different computers
2. Flash_tool.exe
3. Flashing though adb/fastboot (is it the same?)
4. Different versions of TWRP.
5. Enabled USB debugging, OEM unlock & Install from Unknown Sources
Error Messages:
1. Running this -> adb reboot bootloader
error :no devices/emulators found (device was detected in "fastboot devices")

Hi did you manage to find a ROM for the phone?
Hello
Might I know what ROM you are using, and where you got the TWRP? I managed to flash TWRP once on the device, and then install SuperSU when it had a previous ROM.
But I flashed it with blackview's latest ROM I found on their website. Since then, when I flash TWRP, the phone won't boot anymore
I'm using TWRP3.0.0, which is the latest one I found with a scatter file.

Fastboot can't flash anything after upgrade to B389

Hi~
My phone is huawei honor 7.
Fist, I'm sure I have unlocked my bootloader.
I upgrade to B388 today by fastboot flash cust.img and boot.img and system.img which extract from huawei's official update.app.
Then the phone reboot and I leaved for a while, but when I come back, I found it has replace my twrp by official recovery.
So I just reset my phone and wipe cache. When I reboot to system, I receive an OTA update, and I choose "Download latest full package" then the phone finish update by itself. So my phone now running EMUI 4.0.3 B389.
Finally, I enter fastboot model by "adb reboot bootloader" and try to flash twrp, it tell me:
Code:
PS E:\Root\platform-tools> fastboot flash recovery E:\Root\twrp.img

1. If you want to downgrade your firmware version, you need flash a downgrade package first by use dload method. Generally, you can find this kind of package in huawei hiclub ROM thread.
This is Chinese hiclub (club.huawei.com/thread-7268260-1-2.html) that contain this kind of package.
2. I solve this problem by open that unknown source switch . If you don't know where it is, just search it in settings.
3. I know a tool named HiSuit, which may can help you to downgrade your system.
4. Also, make sure you have turn off that f**ing "Phone Finder"!! This is just a s**t made by huawei!!
Hope those can help you~

3. I know a tool named HiSuit, which may can help you to downgrade your system.
4. Also, make sure you have turn off that f**ing "Phone Finder"!! This is just a s**t made by huawei!!
Hope those can help you~

Have you wiped system? That could be the error that twrp gives.
Edit: Don't forget to make a backup of system and data!
Even if the bootloader screen says that the phone is unlocked, in reality it isn't and that's why you are getting the command not allowed text. Just type fastboot oem unlock and your code to unlock it again. The same problem is present on many Huawei phones like the P8 and P9 Lite I've tested after installing an update.
if you want to emui4.0 to 3.0 it was impossible
HUAWEI big chrysanthemum and foolish engineer doesnt want you to flash emui3.0 But you can use the hisuite to demotion.I hope reply is very useful to you

Uninstall TWRP?

Hello Everyone!
I unlocked and installed TWRP on my P20 lite, but now I want to be able to install the updates of Huawei again (especially when Android P is about to release).
So how do I uninstall TWRP and if it's possbile lock my phone again?
(am not that amazing with Smartphone software, so just saying...)

Maybe this thread somehow can helps you:

Don't need lock bootloader to install or receive via OTA official updates.
Lock the bootloader is not possible (maybe it is, but is a pay service).
You can relock instead of lock, but don't do it if your device is not completely stock.
Within the little experience that I have with this team I have investigated the following, when flasheas the official roms by twrp the boatloader is blocked again and the twrp is erased

I still don't really understand how it works:
I downloaded the huawei extractor and extracted the files in a folder on my computer.
I got a update.zip file from my phone and extracted it on my computer.
But when I try to open the update.app file I get an error message saying:
https://i.gyazo.com/abce07c696fb31f15b95c832e3baa899.png
(if it doesn't work: ERECOVERY_VBMET.img: Invalid header crc - Expected: 42613 Got 18415)

Your are partially correct.
Flashing official firmware with TWRP, have to be done with HuRUpdater, during installation the TWRP is replaced by stock recovery, then is your decision keep it or not.
About lock bootloader, mine is unlocked since day one and every time that I install new firmware it keep it unlocked. My experience so far is installing ANE-LX1 firmware in my ANE-LX1 device, probably with other firmware like ANE-AL00 or ANE-TL00 it can be different.

So I can't seem to do "adb reboot bootloader" It will just go to the system.
And when I manually go into the bootloader and try to flash it, I get this error
Before this I tried to flash an other recovery on it which I found on a guide, but after I did that TWRP did get removed but I can't get on the recovery anymore and updating doesn't work either.

In the Fastboot&Rescue Mode screen did you see phone unlocked and FRP unlock ?
Can you share all commands that you are using, can be text like you see bellow:
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash recovery_ramdisk TWRP_3.2.1-0_ANE-LX1_Full_01.img
target reported max download size of 471859200 bytes
sending 'recovery_ramdisk' (24962 KB)...
OKAY [ 0.861s]
writing 'recovery_ramdisk'...
OKAY [ 0.109s]
finished. total time: 0.970s
Are you trying to use command recovery instead of recovery_ramdisk?

1. It says: Phone Unlocked
FRP Unlock
2. When I was in this screen I do:
- cd C:\Users\Louis\Desktop\platform-tools
- fastboot flash recovery RECOVERY_RAMDIS.img
then it gives the error
3. When I try to do it normally, I do:
- cd C:\Users\Louis\Desktop\platform-tools
- adb reboot bootloader

You have to use recovery_ramdisk because this is the name of the partition in this Android version.
I assume that you didn't change the name of the stock recovery extracted, for your case the right command is:
Code:
fastboot flash recovery_ramdisk RECOVERY_RAMDIS.img

Hi all,
Getting a "lock" state is possible indeed. I believe you @kilroystyx had seen it as well on @Merlin_99 's thread:
https://forum.xda-developers.com/huawei-p20-lite/how-to/root-how-to-install-update-t3841557
This will erase all data, except from sdcards of course
Cheers,
AS

You are right, first post was on the August 20th, at that time I didn't knew that was possible lock bootloader, only after Merlin_99 create that thread on September 12th.
