[Q] How to sign files so that they work in Android System Recovery 3e

Hello Guys
I am new to android so please correct my mistakes and i will try to give every detail as possible.
I am having Genx tablet GX pad 300 (It is rooted). By mistake i left my tablet as home and my small brother tried to unlock it. As it was password protected so after 15 failed failed attempts, it got hard locked and Asked for my Gmail ID and PASSWORD to unlock. BUT my wifi was disabled so i was not able to reset it.
An other method was to use ADB and bypass the Password, but The usb debugging was disabled so it didnt worked either
thirdly I saw a method (on XDA) to use Recovery mode to flash AROMA Filemanager and delete the files that were related to the password.
​Now the real problem begins so please cross your fingers.
First i copied the 'aroma file manager" .zip file in external sd card. the file is in the attachment and here is the link to its XDA page, click here
First i booted my device into the Recovery mode and seleted the the option "Apply update from external sd" and selected the update file (.zip format). It gave me error
E Signature verfication failed
Installation aborted
I had Android System Recovery 3e
I did a five hour research and came to know that it is security in android system recovery 3e to reject unofficial installation, i came to know that if i have to fix these errors the either i have to flash a Custom rom like CWM or a MODDED Android system recovery 3e which allows the installation of unofficial apps. the problem is that there is now Custom CWM for my device and i dont know how to make one from the source code. Secondly they have to be installed by ADB but i cant acess my device locked. I also found that sometimes we try to flash a new recovery form within a recovery it may brick the device. i also found that the updates that can be flashed by android system recovery should be named Update.zip and should be officially signed.
I know that there are many methods and apps to sign the .zip files so that they are accepted by the Android system recovery 3e.
i came across apps like zipsigner and signapktic both of them are available on google play. I also used used manual method to sign the aroma filemanager .zip file but every thing i tried it gave me the E signature verification error installation aborted.
My Question is this that how to Sign files so that they are accepted in the ANDROID STOCK RECOVERY 3e
Please keep it simple as possible.:good::laugh:

Download APKManager (5.1). Extract it, copy your zip to ./other/ folder, run cmd.exe, change directory to ./other/ then sign using following command in cmd.exe:
java -jar signapk.jar -w testkey.x509.pem testkey.pk8 your-rom.zip signed.zip.

~It does not require internet connect connection..you can sign in to google account without internet~

Me too!
I have the same problem and can not find an answer for my life! I really need something that can sign the zip for the stock recovery!

do not recognize the command

Error on OTA [EMUI 3.1 6.1.1]

Hello,
I am trying to update my H60-L12 from 6.1.1 to 6.1.16 (and then beyond) using OTA.
I have my phone rooted and with custom recovery. I know I have to unroot and restore stock recovery to get the OTA updates. Yesterday I learnt also that to get 6.1.16 I have to use TAPVPN to connect to the internet via Singapore (thanks to @bcostea for the hint).
Now I find that my phone downloads the update and when it tries to install there is an error in the process at the 6%.
I learnt that the update process logs its progress in the file /splash2/recovery_log
There I find this:
Code:
UI percent:5%.

It seems that my com.google.widevine.software.drm.jar is not the one expected by the process.
That makes some sense, as after I installed the full stock rom, I was not able to apply the pa_gapps (some error related to not being possible to install them in a system that did not had a previous version installed to avoid conflicts) (more details on this are available if anybody has a hint or is willing to trobuleshoot it).
Thing is that I applied open_gapps, which are working just fine, but seem to have a different com.google.widevine.software.drm.jar version.
Till 6.1.1, I was able to replace the com.google.widevine.software.drm.jar file in my phone with one from the system.img of the Stock ROM, and then the update was working.
With 6.1.1 I have not been able to find the right file (one with a SHA-1 hash of 7b4afc644b4d388fe159120f434f769a635a8c5e, seems to be necessary).
I have 3 files with hashes:
6189c99c76c84310f35b967e768440088e140f78
654d36de1c8e9e84979a67e897f36dc17a6f7565
bb6bfd30b3d6d03ecf9531e37bcdb0b5a8123e11
They come from stock, from pa_gapps and from open_gapps, but none of them work.
I put them in the \system\framework folder, but the update still fails with the same error.
Can anyone give me a hint? I am going to try by deleting the file, as I have seen that in the log there is one that is not found and the process does not complain that much.
Maybe someone has the right file in this phone and can send it to me. That would be great!!
Thanks in advance!

Well, it seems I managed to make it work.
Instructions below are without warranty. You know that. It's your phone, if you break it, it's your fault. Not mine. You acknowledge that.
Here is how I did it (if you don't know how to execute any of the steps, just google. Instructions have been provided a million times on how to boot in recovery, how to flash an image or how to do a full backup from custom recovery...):
1. I downloaded the full image of the release I had in my phone (I.e. 6.1.1)
2. Using Huawey Upgrade Extractor I extracted system.img and recovery.img
3. I restarted into custom recovery (TWRP) and took a full backup of my phone to the SD. I then removed the SD.
4. I restarted in fastboot mode and using fastboot.exe I flashed recovery.img and system.img (in my case that did not remove anything from my phone, but as I said before, I took a backup beforehand, just in case).
5. I rebooted the phone. Everything was working just fine.
6. I used TAPVPN app to connect through Singapore, so I could get the update to 6.1.16.
7. The update downloaded and installed as expected.
8. Then I used again TAPVPN to get 6.2.1.
9. Same result: download and installation as expected.
10. Then I rooted again and installed custom recovery by using Honor Multi-Tool.
I hope this helps.

Inazuma ROM for T-Mobile users

So I want to start off by saying that I'm not stealing the developers work. He just seems to not fix the issue related in the t-mobile aroma installer for his 2.8 version rom.
So the error is "Syntax error aroma-config on line 143 col 8"
Go here to download his rom > Thread
Download the one for tmobile 2.8.
After you have downloaded it, extract the zip file and go to "\Inzuma 2.8 tmobile\META-INF\com\google\android"
You are going to replace the file "aroma-config"
Download the fixed aroma installer.zip file from the attachements
Unzip the .zip file, copy and replace the aroma-installer file to the "META-INF\com\google\android" directory
Lastly once you have replaced the file, simply zip all the folders and flash it using your recovery
and that's it. easy fix, the error was caused by a simple code error (which I fixed real quick)

Turn off your tablet then hold volume down and the power button untill you get to the boot loader then use the volume down button to select recovery and press power if you have a custom recovery it will bot to it and it will say team win recovery

Using the right application.
You need SP Flash Tool to install the stock firmware on your device.
Install ROM:
- Install drivers
- Unpack FlashTools, and Click on Flash_tool.exe
- Select "scatter-Loading" and search MT6580_Android_scatter.txt in ROM
- Wait file to be added into Flash Tool
- Select "Download Only" or if upgrade "Firmware upgrade"
- Turn off your phone, remove the battery (if the battery is removable) and replace it after some seconds (and don't turn on the phone).
- Press “Download” button to start
- and connect your phone into the computer via USB data cable.
- The process will start and a red progress bar will appear after color purple, yellow.
- And green circles display
- Finish !
- You can now safely disconnect your phone and turn it on.

Thank you, LS.xD.
The reply you gave are very helpful.
