tried to install JB, used Blackrose = can't get into recovery

Hello Folks,
I'm still stuck with my nexus one since I don't care that much about phones.
I've seen that jelly bean roms have made a significant progress. Thus I decided to give it a shot.
I started with installing adb and fastboot. :good: After that I rooted the nexus one :good: I've used this how to:
c2med blog, can't post links...
Next, I ran blackrose. :good: I saved the rom on the micro sd. Having done all the preperations I wanted to flash the JB rom.
I started the phone in bootloader mode but - unfortunately - couldn't access the recovery mode (ext4). I only get the Android figure and an exclamation mark.
In the how-to it sais i should use fastboot to flash the recovery made by ext 4.
Problem # 1: Ext4 generated a .zip, not a .img file
Problem # 2: I connect the device in fastboot mode, navigate to the adb/fastboot folder and use ./fastboot devices. The phone is recognized and I see the serial number. Next I try "flash recovery...." but I only get "command not found". Now, I basically have no idea what to do.
Which recovery should I flash? And how?
I'm so looking forward to your answers.

What you get is the stock recovery.
Flash 4Ext recovery or Amon RA recovery ( fastboot flash recovery recovery-RA-passion-v2.2.1.img)
Among the several guides to install JB, I suggest you to look at the following post:
http://forum.xda-developers.com/showthread.php?t=1804571
I just finished this morning the following process:
install RA recovery,
install Blackrose and resize partition,
install from SD card Evervolv-Perdo-3.2.0-Nightly-2013.01.13-passion.zip
install from SD card gapps-ev-jb-20120816.zip
I spent a lot of times reading and trying. I had an issue after installing Evervolv-perdo-3.1.0final-passion zip. That's why I switched to the Nightly (JB 4.2).
Once you are set install a2sd from within the terminal emulator on your N1.
In my opinion this is so far the best ROM I ever have had on my Nexus 1.:good:
I am impressed to the extend that I offer to my wife to do the same on her N1. She said no. No to unlock, no to root and of course no to custom ROM.
Good luck

Hi,
thanks for your reply. Thats basically what i did as well. But after using Blackrose i can't go into the recovery mode.
I used the same tutorial. The problem lies here:
"Note: some people have reported having problems getting into recovery at this point (if not move on to step 5). If that happens, luckily for you, 4ext put a recovery image in the downloads folder of your SD card and if you did what I said in step 2 you saved it. Try reflashing that recovery image using fastboot (remember the one that was in SD/Download/4EXT_Recovery_Touch/ and was named "recovery.img"). Put your phone into the bootloader by turning off your phone, turning it on again while holding the trackball down. To reflash the recovery open command prompt and cd to the location of the Android SDK tools. Then type in the following command (replacing "path" with the path to where the recovery image is located on your computer):
Code:
fastboot flash recovery /path/recovery.img
If that does not solve your problems (inability to get into recovery) then I would recommend going back to the cyanogenmod wiki and installing Amon_Ra's recovery. Then you can use it to flash your installation zip."
It seems like I am unable to understand what I am supposed to do. Could somebody give me a step by step advice? I would prefer using some other recovery.img than mine...

It happened to me. I just re-flashed Amon RA recovery from the fastboot mode. Maybe somewhere you missed a step?

Okay I see. Could you give me the exact steps for the fastbood method? :angel: And where did you get the recovery?

In other words open your folder android-sdk-windows installed on the root of your C: hd. Click on the folder platform-tools and download Amon RA recovery in this folder. Left click anywhere on a blank area of this folder then press the key Shift (keyboard) and right click your mouse. In the drop down menu select Open command window. In the CMD, to be sure that the N1 is recognized by the pc (meaning the right drivers are installed) type ADB devices and press enter. You should see a string of numbers like HT9C......
Type adb reboot bootloader and press enter. You are in the fastboot mode ( and mood if I may say so) and the phone shows that it is in the bootloader. You can check again that N1 is recognized by the pc by typing fastboot devices. Same string appears.
Type fastboot flash recovery recovery-RA-passion-v2.2.1.img.
After the installation is completed boot in recovery, select Flash zip from sdcard, select the ROM you have dropped on the card. When the installation is completed go back to Flash zip from sdcard ( you are still in recovery mode) and select the gapps you have dropped on the sdcard.
Go back to Reboot system now. You are then out of the recovery and it takes some times for the N1 to boot to this beautiful JB

As c2med posted in his guide, sometimes, people lose their recovery when they repartition using Black Rose. Hence, its always best to have Amon-RA or 4EXT flashable .img file in your PC so that incase you lose recovery, you can always flash it back.
Once you are in bootloader ( also called FASTBOOT mode) you can flash your recovery.
Then reboot into recovery from FASTBOOT (Shutdown and then restart using the recovery combination)
Once you are in recovery, follow the steps in c2med's guide (wipe cache/dalvik/etc - except sd-card ofcourse) and flash your ROM from sd card.
Then reboot into JayBee

In the screenshot you type:
$ ./fastboot devices
then you type:
$ flash recovery ......../recovery.img
Command not found.... Sure, flash it's not a command...
You need to type fastboot command first!
$ ./fastboot flash recovery ......../recovery.img

Thank You! That's what I figuered out last night. Of course I also tried "fastboot flash" but forgot the "./". That was the key. Now the JB ROM works like a charm.
New Problem:
I can't install google apps. In fact I don't really need them. I only use a few apps and found the .apk files with google. Unfortunately the "official" Google apps like chrome don't work.
Plus, I wanted to install the camera (laggy in the evervolv - rom) and keyboard from here.

When I try to install the .zip files in recovery mode I always get an error because of the signing... any help?

When you're in recovery, select "Flash zip from SD card" and then select "Toggle signature verification" to disable signature verification, and then "Choose zip from SD card" and navigate to the zip file that you want to flash.

[GUIDE] Downgrade Zenfone 2 Laser to any official firmware

I have discovered multiple ways of downgrading ZenFone 2 Laser out of which two methods proved out to be easy and reliable. Both methods have been tested and are working.
Method 2 doesn't require root while method 1 needs root access.
Pre-requisite: Stock firmware zip file. You can find download links from index thread for all variants.
WHILE THIS GUIDE HAS VERY LESS CHANCES OF MESSING UP YOUR DEVICE, HUMAN ERROR CAN ANYWAY HARM THE DEVICE. I AM NOT RESPONSIBLE FOR ANYTHING YOU DO TO ANY DEVICE. YOU ARE DOING THIS AT YOUR OWN RISK
METHOD 1: Requires ROOT-
Short instruction:
Some users say you can downgrade by renaming the OTA zip to correspond to a higher version but that will NEVER work because the update script has this line
(!less_than_int(1457089250, getprop("ro.build.date.utc"))) || abort("Can't install this package (Fri Mar 4 19:00:50 CST 2016) over newer build (" + getprop("ro.build.date") + ").");
Click to expand...
Click to collapse
The recovery reads ro.buid.date.utc value from buid.prop. If the value is less than the value in updater-script (like the value highligted in above quote) any recovery will not flash it, neither stock nor custom. Just increaase the value of ro.build.date.utc (in build.prop) to any value higher than the value in updater-script and then flash the zip via recovery.
Detailed Instructions:
1. Open updater-script from the firmware zip. It will be found in /META-INF/com/google/android inside the .zip
2. look at the first line (!less_than_int(1457089250, getprop("ro.bui....
3. The value 1457089250 is taken as an example, your updater-script may have a different value. Keep a note of this value.
4. Install any root file manager like ES file explorer (if you dont have already)
5. Goto /system (the system folder) using the root file manager. Grant root access if prompted
6. Open buid.prop file as text and look for the line "ro.build.date.utc=1446585430"
1446585430 is taken as example, your phone will have a different value.
7. Now increase this value in build.prop to any number greater than the value you noted from updater-script
for example, if my updater-script has 1457089250 this value and buil.prop has 1446585430 this value, I will simply change the value in build.prop to 1546585430 or 1448585430 or 1457089251. Any number greater than 1457089250 will work in my case.
8. Now reboot to recovery (vol down + power)
9. Select "apply update from external sd card" select your firmware zip file, and then select yes to flash. It will take 5-10 min
10. (optional but recommended) Wipe factory/data . If you don't do this, you will see the annoying "Android is upgrading.." screen which takes around 30-40 mins to reach home screen.
Method 2: Without root, requires computer
Short instructions:
As I mentioned earlier, recovery reads "ro.build.date.utc" But you can bypass this check by erasing system partition.
Just do
Code:
fastboot erase system
from fastboot mode and then flash the zip from recovery
Detailed Instructions:
1. Install Asus drivers to your computer. (link in index thread)
2. Download adb_fastboot.zip and extract its contents
3. Reboot your phone to 'bootloader mode'. To do this turn of your phone completely. Hold "volume down Up" button and then press and hold power button. Release power button after Asus logo appears and then release volume down button. Your phone is now in bootloader mode.
4. Connect your phone to pc via a reliable usb cable. Look at your phone screen. It should display "Fastboot mode!"
5. Now go to the folder where you have extracted all the files. Holding down shift key, Right click on any point on white screen. Then click on 'open command window here' from the menu that appears. Command Prompt will open now
6. On command prompt type
Code:
fastboot devices
and hit enter
and check if it is detecting your device.
7. Then type
Code:
fastboot erase system
(this will erase your current OS, you are warned!)
8. After it is done type
Code:
fastboot oem reboot-recovery
to boot into recovery mode
9. Select "apply update from external sd card" select your firmware zip file, and then select yes to flash. It will take 5-10 min
10. (optional but recommended) Wipe factory/data . If you don't do this, you will see the annoying "Android is upgrading.." screen which takes around 30-40 mins to reach home screen.

Successfully downgraded to 1.16.40.763 from 1.17.40.1234 without root
Thanks!

"Failed to mount /asdf" error is harmless you will get that error even on latest twrp. You can ignore the error and use the MM stock recovery like normal. Recovery will do its job it can format, install updates, clear cache and everything, you just need to ignore that /asdf error
But you can use any stock recovery from any firmware version lower than or equal to your current firmware version. Drawbacks: You cannot apply update to MM OTAs if your recovery version doesn't match the current firmware version.
Going back to stock 1.13 is a bad idea. I would recommend you to stay on MM since it has many performance improvements.
But still if you want to go back to lollipop, consider downgrading to the last lollipop update i.e. v1.17.40.1531

I got a 412 mb ota update some days before. I downloaded it. Apply it for proceed. Then it start checking system as usual phone restarted. But update did not happened. Instead this same error show up. Then i can only reboot system. Got an update failed message.since that when i check for updates iam not even getting any. May be it will be solved by a factory reset .but even if i get an ota. The update wont proceed .because the recovery wont allow me to do that
And also that wipe cache partition also results the same error .so without solving this error i cant update to the latest MM too :/ .

In my experience, the most reliable method is to
extract the recovery from the version of stock ROM you want to upgrade or downgrade to
Flash that recovery with fastboot
Wipe /system in fastboot
Reboot to recovery and update with the stock ROM .zip
Or
Even easier, use Sziraqui's fastboot ready .IMG files and just flash them via fastboot.:good:

The recovery is included in the stock ROM zip file. Extract the zip and you will find it inside.
Presumably if you want to flash the stock ROM you have already downloaded it?

Thank you.
Can ZE551KL use the recovery.img from ZE550KL? My ZE551KL has the extra 1700(AWS) band.

Please where are you guys downloading your stock rom from?
The stock zip is NOT flash-able like a custom ROM .zip. That's not how it works. If the Roms you have are custom recovery flash-able, they are not the OEM rom, they have been modified.
All the Roms I have come with a recovery.img file...
Then again if I have to explain how to use fast boot to flash the recovery, there is a good chance you shouldn't be messing around with fast boot.......

You don't need to unlock bootloader for flashing stock recovery that you downloaded from the above mega drive.
To flash the recovery.img (or any .img) You need to have Adb and fastboot files in your pc as well as Asus Zenfone drivers installed
All info and downloads for adb and fastboot can be found here
Search and download Asus ZenFone 2 laser drivers.
Once you have your pc setup with these tools,
With Administrator priveleges, locate the folder where adb.exe and fastboot.exe files are present. Hold down shift key and right click on that folder and select "open command window here". Then reboot your phone to fastboot mode [power off, hold vol up +power, release power when logo appears]
Connect your device to pc.
Type the following command on cmd
Code:
fastboot devices
Output should be something like this
Code:
FCAHSJSJJAKAK fastboot
This command will check if your device is connected or not
If output is blank, device is not being detected.
To flash recovery.img, copy the recovery.img file to the same folder where fastboot.exe exists and then type
Code:
fastboot flash recovery recovery.img
Output is easy to understand, if it says [OKAY] then flashing succeeded

Tried downgrading ze551kl by fastboot erase system then installing .zip from Asus website (via sdcard). All of the Asus updates except the earliest fail with 'fota return code 403'.
1.14.40.550 installs ok but then boots (gets as far as displaying the wallpaper), gives an error message in german (looks like 'android media process stopped') and goes into boot loop. Anyone seen this before?
Also, any way to build a recovery.img from the Asus update files?

invalid boot image whenever i flashed stock recovery,any one know why ?
What i do is flash the stock recovery and flash relock bootloader.

I think OP needs a small correction to enter into FASTBOOT you need to press volume up and power instead of volume down and power buttons

No, unfortunately not.
If XDA has no solution, who else?

I have the same problem, this is inside the file
Code:
#!/sbin/sh
# Include device-specific vars
source /sbin/bootrec-device
# Turn the LED off
echo 0 > ${BOOTREC_LED_RED}
echo 0 > ${BOOTREC_LED_GREEN}
echo 0 > ${BOOTREC_LED_BLUE}
that error is because this file bootrec-device located at sbin folder always missing when reboot system or recovery
I have try many way
-flash stock rom with flashtool
-flash rom via recovery
-wipe via adb and fastboot
-chmod this file bootrec-device to read only
-remove this file postrecoveryboot.sh just come back after reboot recovery
all that way doesn't work
my Xperia unable to boot right know :crying:
maybe i'll try search what's file that create this??? postrecoveryboot.sh
where's boot script locate???

Thanks for that much information. :good:
A possible 'emergency solution' so that your device reboots again could be attached link.
What really surprised me, no one else has this ERROR: 2, and if not, why not?
http://www.flashtool.net/index.php

You can fix this 'postrecoveryboot.sh' Error 2 with a lower version twrp
I use twrp 2.8.7 which has been uploaded by someone from here androidfilehost.com/?fid=24052804347811669
flash with "fastboot flash boot boot.img" only if you UB, on LB try downgrade your twrp version
and then via file manager, just chmod the file bootrec-device located at sbin folder with read only access
my phone can only be booted only with rom existenz, and it was frequently rebooted and my battery status is unclear, sometimes 65% during the initial boot, and then only a 5% reboot afterwards
I have flash using flashtool with many based rom from 10.5.1.A, 10.6.1.A, 10.7.1.A latest, but it still does not make my phone work just to show sony screen flickered and died with the indicator is still red
all the problems occurred after I had this problem 'postrecoveryboot.sh' Error 2
I still do not know how to turn off the script, when I delete the file after reboot definitely go back there
hoping my phone can be normal again sometime

Could the cause for the error be a kind of provider branding?
So deeper implemented than the usual firmware.
My device was delivered via German Telekom.

After installing Multirom v33 the error message is gone!
Dont ask why, both recoverys, the new one into the FOTA partition from attached link und the older, normal one 3.0.2.0 are error-free! :good:
https://forum.xda-developers.com/xperia-z/orig-development/mod-multirom-v33x-xperia-z-t3432385

I have installed the Modified recovery FOTA, before this error happen all working fine any custom rom working
but after this error, i can boot into recovery and install rom then reboot got bootloop, charger just show blip screen logo
just wanna try your idea with the Multirom v33 non modified

Google has no answer for me.
Every time I enter into the recovery and push the message button I get this ERROR: 2.
Everything works fine, its latest TWRP 3.0.2.
Could you tell me something about this error message 2?
What is 'postrecoveryboot.sh'?
How can I get this red message off / without error?
thanx in advance

Download latest recovery 'twrp-3.0.2-0-yuga.img' from link 1.
Put it to your Phone, turn of, push volume + and insert USB-cable for flashmode.
Blue LED-light appears.
Type -fastboot flash boot boot.img
-fastboot reboot
in ADB-connection CMD on your PC --> thats all.
Optional you can use the Tool in link 2.

I wa sure to copy the .img file in "platform-tools" folder in my PC and with cmd type "-fastboot flash boot boot.img" and not to have the file inside the internal memory of my Xperia Z. Obviously i think to rename "Twrp-3.0.blablabla" into boot.img

Yes, very correct, copy and rename the file into 'boot.img' to your ADB-folder and flash it. :angel:

Finally with some free time i unlocked and flash the latest TWRP on my old Xperia Z. And yes i've got the same error "ERROR: 2". But everything works from backup to restore and flash Custom ROM. So i think we can nevermind about that

I have the same.
Sometimes my phone randomly reboot, and seems to be some app cause this reboots.
It was happend more and more often. And suddenly couple days ago my phone start to bootloop (just endlesly booting at xperia logo).
I have F5121 stock 8.0 Oreo and done all like in this manual https://forum.xda-developers.com/t/...els-latest-34-4-a-2-118-25-sept-2018.3594502/
So I was have rooted kenrnel twrp 3.2.3.0+DRM-Fix +magisk +FCS_1.3 +debloat script.
Almost 2 years of no problems and this surprise.
When I load to twrp and press menu button i see this:
Updating partition details...
...done
Unable to mount storage
So I was trying do backup of all partitions and after that I go in in wipe menu => advanced wipe => checkbox cache partition => fix patition
than I try to fix all patitions - it doesn't help.
So I do this:
wipe menu => advanced wipe => checkbox data partition => change to exFAT filesystem then => change back to EXT4 filesystem and restore data from backup. And do system/data partitions
and try to restore my backup - and it don't work.
EVEN my older backups don't works - I always become bootloop on xperia logo.
When I download twrp backup to PC and unpack cache.ext4.win\recovery I see file with name last_log.
Thats how last strings of file last_log look like:
~
ro.bootimage.build.date.utc=1533015130

keyguard.no_require_sim=true
tombstoned.max_tombstone_count=50
Running boot script...
I:/sbin/postrecoveryboot.sh process ended with RC=0
Done.
I would like to hear some ideas why that may happen (Unable to mount storage). Coz i lost part of my data and don't wanna have the same experience again and again in future.

[Solved] Error while flashing Katkiss from CWM v6.0.5.0

Dear friends I need help!
I've tried to flash my tablet but I've got an error message while flashing Katkiss 6.0
What I did:
downloaded Rom.(md5sum is OK)
my bootloader is ww_epad-11.4.1.17-20140711
recovery CWM v6.0.5.0
previous rom zoombi pop
/format data
wipe data factory reset
install zip from sd card. (from internal storage or micro sd card)
And I have got the following error (in attachement)
Please help, my tablet boot only recovery now.
Thanks in advance for the help

trying to boot in fastboot mode when children let me try that...
Edit: fastboot ok.
I placed the the files
KatKiss-6.0_TF701T_033.zip
open_gapps-arm-6.0-pico-20170120.zip
UPDATE-SuperSU-v2.79-20161211114519.zip
In
C:\Program Files (x86)\Minimal ADB and Fastboot

ok I don't know how to proceed now.
Seems I cannot change the recovery from CMW to TWRP,
My bootloader is 11.4.1.17 and the tutorial to install TWRP says in capital red:
MUST BE ON A BOOTLOADER 11.4.1.27, 11.4.1.29 or 11.4.1.30
So how can I do?
I there a way to upgrade the bootloader to be able to install TWRP?
Or should I Flash the custom rom from fastboot?
My TF701 in not booting anymore.... only bootloader and recovery CMW
the positive thing is :
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot devices
15C3E10090400000011FA8580 fastboot
Please help

I have been able to flash CROMI X (unfortunately with strong battery drain) so CMW is able to flash but for some reasons not Katkiss 6.0.
I have been told that my problem is not ROM related... So it is recovery related?
What is the better option to get katkiss on my tablet? Flash the recovery to get TWRP even if my bootloader is 11.4.1.17 and the tutorial to install TWRP says in capital red:
MUST BE ON A BOOTLOADER 11.4.1.27, 11.4.1.29 or 11.4.1.30????
There is a technical reason about this warning?
Edit: I found this on an old post:
You can try this:
Download the stock recovery from here: http://droidbasement.com/db-blog/?p=3210
Copy the image to your fastboot folder.
Download the Asus firmware, unzip the file once and copy it to your internal SD.
Boot tablet into fastboot
Issue this command
Code:
fastboot boot recovery.img
Note: Do not flash the recovery, just boot it.
It should recognize the firmware file on your tablet and flash it.

Would this method work to get the latest stock rom from Asus?

Got your PM and will try to find some time at work today. Hang in there and don't do anything to make it worse

Ok, work was crazy busy so it took a bit longer.
If you flash a recovery that is incompatible with the bootloader nothing happens. Until you use the recovery... That could permanently brick the tablet. So heed the warnings, they are there for a reason.
Ok, let's try to get you on the latest bootloader. It's no suprise at all that nothing boots if you try to flash a Android 6 rom on an Android 4 bootloader....
Download either WW or US package from here: https://forum.xda-developers.com/showpost.php?p=61045480&postcount=2
That zip contains the latest bootloader and a compatible TWRP recovery. Flash the zip in your current recovery just like any rom, then reboot.
When you flash a bootloader or recovery you actually write those files to the staging partition. On the next boot the bootloader will unpack it and write everything to it's proper place.
So it's essential that you flash, then reboot. Does not matter that the boot does not go anywhere. The first part, flashing the contents of /staging to it's partition(s), will happen anyway.
You should see a brief blue bar filling up when that happens. It does not take long.
Boot back into fastboot and check your bootloader version.
Enter recovery through RCK and that should be TWRP now.
Then format /data. Do not wipe it, format it. Do not interrupt it. Wait for it to finish even if it takes an hour (a full battery is a must before you start this). The format command is under the Wipe menu.
Unfortunately the formatting in this kanged TWRP is pretty buggy, but I still like it better than CWM.... If you get lots of error messages after the format (cannot mount this, cannot mount that) go into Wipe > Advanced > select Data > Change or repair file system > Change file system > choose ext3 and execute
Note: The button you have to swipe is pretty "sticky". Swipe it slowly and fully
Reboot to recovery
Go back into Wipe > Advanced etc and change the file system back to ext4
Reboot to recovery
Now everything should be ok, try to mount/unmount data.
Finally you are ready to flash Katkiss
If the bootloader flash does not work, we can try to flash Asus firmware in fastboot, but try the above first.

Thanks a lot to take time to help me.
Will try that tonight and I'll let you know the result.

Thanks a lot!
It was just like you said.
I had to format to ext3 and ext4 because I had errors.
Battery seems to be very good. Just the screen display is very white, needs color saturation and contrast I guess...
Thanks again you save my tablet.

Now that's what I like to read! :cyclops:

[ROM/GUIDE] How to Restore Stock A2017U B20 Firmware and Re-lock Bootloader

First of all, I would like to say thanks to @DrakenFX, @tenfar, @rczrider, and @tennear for their work on the Axon 7.
Code:
/* Disclaimer
* I am not responsible for bricked devices, dead SD cards, thermonuclear war,
* or any other mishaps that may occur. YOU are choosing to make these modifications, and if
* you blame me in any way for what happens to your device, I will laugh at you.
*/
This guide is intended to help anyone wishing to return to stock B20 firmware on the A2017U for the purposes of re-locking the bootloader (either for sending a device in for an RMA or whatever you may need). After much trial and error, I have finally come up with a guide and attached all necessary files to do this. I performed the following steps on my Axon 7 2017U on the B29 firmware and successfully downgraded to the B20 firmware with a re-locked bootloader.
Here are the files you will need:
Stock system
Stock boot stack
Stock fastboot
Stock recovery
TWRP
Make sure you have ADB and fastboot set up properly on your computer.
Use the TWRP linked in this post. I know for sure that this version works towards the end of this process when your bootloader is locked again.
After you have the zip files, you will need to move them to your phone to flash in TWRP. Follow these steps:
1. Make a backup of all of your important data. EVERYTHING will be wiped in this process, including internal storage.
2. Power off the phone.
3. Download the the axon7tool executable file from this link: Here Check the post for instructions pertaining to drivers needed.
4. Boot the phone into EDL mode. Do this by holding down the Volume Up and Volume Down keys simultaneously and then plugging the phone in to your computer while keeping these keys pressed. (The phone's screen will be completely black and it will appear like nothing is happening. This is EDL mode.)
5. Open a command prompt in the directory with the axon7tool executable. (Windows: right click while holding shift and select "Open command window here." Linux: Open a terminal and cd into the directory)
6. Dump your gpt with the tool. (Note: you may need root access to run the following commands on Linux)
Code:
Windows: axon7tool-1.5-win64 -r gpt
Linux: ./axon7tool-1.5-linux -r gpt
7. The axon7tool will automatically reboot you. Reboot to TWRP.
8. Make a backup of your EFS partition by going to "Backup" with only the EFS box checked.
9. Copy the "TWRP" folder from your internal storage to your computer. This folder contains the EFS backup.
10. Go to "Wipe" -> "Advanced" -> "Format Data." Type "yes." WARNING: THIS DELETES ALL DATA. MAKE SURE YOU HAVE A BACKUP.
11. Reboot back into TWRP. Ignore anything TWRP says or asks you to do upon a reboot.
12. Copy the "B20_stock_system," B20_stock_bootstack," and "B20_stock_fastboot" zip files to your internal storage.
13. Flash the stock system zip first, then the boot stack zip, and finally the fastboot zip.
14. At this point you are on the stock B20 system, but with an unlocked bootloader. TWRP will probably be overwritten, so follow these next steps regardless.
15. Reboot the phone and let it get to the set up screen. This step can take a while; my Axon took almost a minute to get off of the ZTE splash screen initially.
16. As soon as you see that the phone boots, power off the phone and reboot to EDL mode.
17. Flash TWRP again with the axon7tool as it has been overwritten at this point and will be necessary soon. Download the linked TWRP recovery image and rename the file to "recovery.bin" Place it in the same folder as the axon7tool. Flash the recovery. (Note: you may need root access to run the following commands on Linux)
Code:
Windows: axon7tool-1.5-win64 -w recovery
Linux: ./axon7tool-1.5-linux -w recovery
18. Reboot the phone into the bootloader. You can do this by going to TWRP and by choosing reboot to bootloader or by manually doing so.
19. Type "fastboot oem lock" into a command prompt. This will lock your bootloader.
20. After I did this, I thought I was done. However, when I rebooted my phone, I saw that /data required a password to be decrypted upon a reboot. This is why we flashed TWRP. Go into TWRP and format data again.
21. Copy the "TWRP" phone from earlier back onto your internal storage. Restore your EFS in case anything has happened to your IMEI in this process.
22. At this point your phone is completely locked but with a custom recovery. To restore the stock recovery, reboot into EDL mode and replace the TWRP recovery.bin file from a few steps ago with the B20_stock_recovery.bin file you downloaded. Rename the B20_stock_recovery.bin file to recovery.bin and make sure it's in the same folder as the axon7tool.
23. Flash the stock recovery with the same commands for the axon7tool as listed earlier for TWRP.
24. Profit

As tennear has noted, do NOT backup or restore the EFS partition.

Never restore EFS using TWRP. You will lose its contents and probably your IMEI.

@tennear Thanks for the heads up. I'll remove that part from my guide.

Hi
I flashed the twrp recovery on locked bootloader but i lost my recovery
My firmware was 0b15

Were you trying to restore your whole firmware to b20 as the guide demonstrates or were you only flashing the TWRP linked in this post?

Oh no...
I had tried to flash twrp to install a custom rom...
And i used the Miflash tool to flash it,but i forgot to unlock bootloader, and i think if i flash the stock recovery, i will be able to change the situation...
Are you think this will work?
Or i have to downgrade my firmware to 0b20 and then flash the full pack?

You can try, but I'm not sure if it would work. The recovery is for stock b20 so try it at your own discretion.

Every time I try to do the fastboot oem lock it fails, I have the twrp you mentioned in the post and followed the steps as listed. Did you run into this issue?

I'm getting the following error (Win 10). Others have gotten the same error in various versions of linux, as well. The only one who resolved the error had forgot to elevate his terminal (which I've done):

I'm seriously stuck. I did everything up to step 15, but it starts to boot, sits at the ZTE screen for about 30 seconds, then shuts off. When I try to reboot, it does the same thing. I had two problems getting up to step 15. The first problem was that the axon tool refused to work. I posted the error a few days ago, but no one replied. Since the phone has to go back to ZTE and I'm running out of time, I decided to press on.... since it only seemed like a backup, which I have plenty of.
The second error was at step 12. After Step 10, I could not read/write anything on the internal sdcard. It is obviously encrypted... which begs the question... what good is step 10 if it doesn't blow away the encryption? At any rate, I copied the the three zip files to an external SD card flashed the bootstack and fastboot, both of which completed without error.
As of now, I can get into the ZTE MiFavor recovery and then to bootloader mode, but it won't take any of the fastboot commands. Running fastboot devices shows the phone, but every fastboot command fails with "unknown command".
I've also tried flashing the B20 system and fastboot zips from the MiFavor recovery, but both say "signature verification failed".
Not sure what to do now.

I just tried the official ZTE file here, but it said "signature verification failed" also. Not sure how that's possible.

@Yoshi_Guy
In step 22) where stock recovery has to be restored, instead of reusing axon7tool in EDL mode, maybe it would be easier to flash stock recovery by the signed tenfar TWRP itself (by using TWRP Install/flash image option, boot partition). This is a kind of "hara-kiri" (current TWRP destroys itself) but it should work.

That's quite odd, what version of Linux are you using? Also, are you able to try the Windows version of the tool? I've used the tool on Arch Linux and had no problems. Also, the program does need to be run as root, as you mentioned. The signature verification probably failed because you are trying to downgrade your version, I wouldn't recommend using the official ZTE zips entirely. I would take what you need and flash just that, downgrading is rather complex.

Thanks for the guide, but wish you would've used androidfilehost. I hit MEGA quota at 80%, so I'll have to wait til late tonight to give this a shot.
nvm: using megadownloader now
