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
Hi, I found a way to fix this bootloop which happens after you flash the latest ota update if you have unlocked and rooted your stock rom.
I own a HTC E8 China Unicom [M8Sw - dual sim], but I think it will work on other variants.
It is the SU binary/files which are preventing the phone from updating correctly.
You can also restore a clean unrooted TWRP backup and do the OTA update.. it will work just fine.
This tutorial is for those who don't want to lose their app data and modifications.
To be able to update... you need to fully unroot the phone before. Well, this was previously not possible due to system write protection.
(There are also other methods of unrooting. (deleting the SU files manually with the file manager of TWRP recovery) This doesn't work, I have tried it myself..often cause bootloops.)
But now we have a custom recovery mod which enables us to write to the system partition and thus can fully unroot with SuperSU app itself.
Requirements:
-some expertise with adb/flashing/twrp recovery management will be needed.
-stock firmware.zip, inside the OTA zip file, where you will find you stock recovery,boot image, etc
-Stock ROM, rooted with no modified existing system files
-TWRP Recovery from @Captain_Throwback works fine. I used the 2.8.6.0 one. http://forum.xda-developers.com/one-e8/orig-development/recovery-twrp-touch-recovery-t3060188
-untouched Stock Kernel Modules (IMPORTANT)
-SchKernel Extra 3.3, to gain write permission to /system http://forum.xda-developers.com/one-e8/general/schkernel-extra-3-3-t3200090
[UPDATE: SchKernel Extra has been updated to 3.5 and the old one is not available for download on the other thread. You can find attached at the bottom of this section ver3.3 which I had used. Please don't use ver3.5 as a user has reported having bootloop with that.)
-Battery +80 charge recommended...the process gonna demand a lot of power.
-Patience... loads of it....
Disclaimer: I am not responsible if you brick or damage you phone!!
Before you flash anything, be sure to have a working twrp full backup of you phone! In case anything goes wrong.
STEPS:
1. Copy the untouched kernel 'modules' folder [found in system/lib/ in your phone] to another location ( for e.g. to your internal phone memory), you're gonna need it later.
2. Flash the twrp recovery if you haven't already and boot into TWRP recovery.
3. flash SchKernel Extra 3.3 kernel mod. It will launch the aroma installer. There will be options as overclocking/underclocking etc..
I left everything on STOCK option, disabled Swipe2sleep, unselected the everything in the optional addition page. Then went to install it.
4. Reboot, and open SuperSU app, go into setting, tap the FULL UNROOT option, this might take a while. The first time, when the unrooting notice shows and it seems that the app is not doing anything, you might be required to exit the app by pressing home button. Then open the app again and redo FULL UNROOT option. If you exit the app and when re-opening it, the "unrooting notice" is still there, then it means it is working. This might take a bit of trial and error.
5. Ultimately, SuperSU app will close. Then you will need to reboot. You will see that SuperSU is gone and that you have no root access.
6. Now, turn it off again to go to fastboot. Connect to PC and flash the stock boot.img via adb to restore the stock kernel.
8. Then, in twrp recovery, mount /system partition and got to advanced >> file manager..
9. Now browse to /system/lib/ and delete the 'modules folder'.
This is because the SchKernel Extra 3.3 kernel mod flashed previously has modified your kernel modules and when you will try to update the OTA, the stock recovery will report that the kernel modules (xxxxx.ko) has be modified and it will stop the OTA update process.
10. Remember the previous untouched stock 'modules' folder you copied previously, now move it to /system/lib/HERE , to replace the deleted folder.
[DO STEP 9 BEFORE - Don't try to overwrite the folder, it won't be possible. It said operation failed for me. ]
Optional: You might also want to delete su.d folder in \system and init.d folder in system\etc
these files were for the custom kernel and won't be needed anymore.
11. Reboot into fastboot mode, connect to PC (if not already), flash stock recovery.
12. Now, you're good to flash the OTA updates. :good:
-Download it, if not already done.
If ever you have downloaded from PC and copied it to phone, and for whatever reason the phone is not detecting the zip file and asking for install.
Just move it to you exeternal SD card and rename it to "ptt.zip" , go into stock recovery and go down the list to "apply update from SD card"
and it should flash the zip file. When done, select the reboot option and it will say reboot to flash firmware.zip and the will boot. :fingers-crossed:
When booting it will take some time (3 to 8 mins), and then go to the "Android is updating - optimizing apps" screen. This might take a lot of time if you have a lot of apps installed. The phone might get really hot during this process.
When the OS finally boot completely there will be an "HTC" screen and an exclamatin mark in the notification bar. NO WORRIES, it is the just the update working. It will go away when the update is fully processed.
After OTA update is done, you can make a twrp backup of the unrooted system, so that you can restore it for future OTA updates.
If some steps are confusing, feel free to ask for any clarification

Click to expand...
Click to collapse
how did you flash it exactly?
Did you flash it thought TWRP recovery?
also...what variant of HTC e8 are you using?
Thank you for this guide. :good:
For the newbies, here are exact instructions for each step. TWRP is required; presumably you have this because you've rooted your phone. (If you haven't rooted your phone, what are you doing here?)
Note that rebooting to TWRP can be accomplished in several ways:
Long-press the power button; when prompted choose Reboot. When the screen goes black, press and hold the Volume Down key. This will take you to hboot; from there choose Recovery.
Enable developer mode from settings, plug in to a computer, and issue the command adb reboot recovery.
Also note that it is prudent to do a full TWRP backup to external storage (microSD, USB OTG) before anything else, so you have a good recovery point if things go wrong.
To copy the system/lib/modules directory, you can use a root-enabled file explorer or TWRP. To do it in TWRP:
Reboot to TWRP.
In TWRP, select Mount. Make sure that system is checked.
Back to the main TWRP menu, select Advanced.
In the advanced menu, select File Manager. Then navigate to /system/lib/modules.
Tap on Select, then Copy Folder. Navigate to a new location - I used /sdcard/Backup - and tap Select again. Don't use your external SD or USB-OTG, they may not preserve permissions correctly.
To flash the SchKernel Extra, copy the ZIP file to your device, reboot into TWRP, and select Install. From there, navigate to where you copied the ZIP file and select it; then follow the prompts as sanijsnj specified.
Removing SuperSU works exactly as described. Don't forget to reboot at the end (although it may not be necessary).
To flash the stock boot, in a cmd window where you have the Android SDK, typically in the sub-folder platform-tools enter: fastboot flash boot boot.img (boot.img from the OTA ZIP).
To delete and restore /system/lib/modules, follow the steps above, starting of course from your saved 'modules' directory and copying to /system/lib.
To flash the stock recovery, again in the cmd window enter: fastboot flash recovery recovery.img (recovery.img from the OTA ZIP).
This tool has been heavily modified for the zte max pro, it was originally posted as the axon 7 tool. Not all features have been included as not all work as of yet for the pro.

If you have problem with loading Widgets find build.prop file in mobile or download from Playstore BuildProp Editor
This problem is solved very easily with root access. You just need to fix one line in the build.prop file:
ro.freeme_freemanager=1
ro.hct_autostart_manager=1
In these lines you need to change 1 to 0
Magisk manager works without TWRP great
In TWRP recovery dos not work mtp
And big problem with TWRP is if you formating data then mobile can not recognize sim card (IMEI null,baseband unkown)
If anybody have solution thanks.
