Hello everybody !
Ok, I am use to not ask any help, and to find out by myself. But I have to admit I don't have any idea remaining to solve this problem.
Let me explain you the situation :
I explain everything with details to not waste your time when you will help me !
When I first bought my Zenfone, everything worked properly. Then, I decided to flash a Custom ROM (to remove the bloatware, and to get the others optimizations). So what I did :
- I unlocked the bootloader,
- I flashed TWRP,
- I installed my custom ROM (SuperZen R15, super clean install) => at this moment, everything is working perfectly,
- I installed a custom Kernel (ProjectT, v56) by fastboot => here we are, the problem just appeared.
At this moment, the WiFi issues appear. When I boot the phone, I can turn on the WiFi (in most cases), then, WiFi just turn off. It is impossible to activate it again. In the best case, I can switch on/off the WiFi, but as soon as I download something, the WiFi just turn off immediately. Often, I just don't detect any network. In the worse case, it is impossible to activate again the WiFi, the ON/OFF button is grey.
So here is what I tried to get it back :
1) put the standard kernel with my TWRP backup => no success
2) flash another ROM (CM12, Paranoid Android, Barebone,...etc) => no success
3) flash my whole TWRP backup (system + kernel) => no success
4) flash the official Asus ROM (recovery.img, system.img, boot.img, droidboot.img) => no success
At the moment, I started thinking that maybe the WiFi just "forgot" my WPA key. So I modified the build.prop :
5) modification of the build.prop by adding the line ro.securestorage.support=false (instead of "true") => no success
6) flash the last Asus update 2.20.40... => no success.
...
I haven't any idea remaining !So I need your help ! This problem seems very standard, but I just couldn't find any solution yet !
P.S : I almost forgot. I talked about the wiFi signal, but it is exactly the same for the bluetooth signal : working on first boot, then when I use it, it just stop working and disconnect itself, and then, impossible to activate it again (grey button)
=> My last idea was to flash the radio directly by TWRP, but I didn't find any radio files for the zenfone 2...
Many thanks for your help, and thank you for reading everything !!

Try setting your phone as a wifi hotspot. If other devices are able to detect your device, it is a software issue. Or else, you might have to book an appointment with the Asus service center

You're such a genius ! I will try this evening ! Thanks a lot !
Didn't do anything. It's not working. I was thinking my wifi was just broken, but something creepy happened this morning. The Wi-Fi worked again (I downloaded one thing to be sure !) and then... My phone froze, and reboot... Is the devil inside my phone ??
SOLVED ! If someone has the same problem, just flash the stock ROM via ADB Sideload !
Step by step :
1) You go here, and download your version of the stock ROM : http://www.asus.com/fr/Phones/ZenFone_2_ZE551ML/HelpDesk_Download/
2) (If fastboot/adb drivers are installed) Go into your recovery (Advanced in TWRP)
3) Connect the phone to the PC, type WINDOWS + R , enter 'cmd'
4) Go into your firmware directory you just downloaded, and type : adb sideload 'thenameofthefirmwarefile'.zip
5) Wait (a loooong time), and here we go, reboot, and your phone work again.

can you tell me what firmware you used exactly? because i tried to flash the first one, from the asus page.
But it says that i have a newest build and it doesn`t lets me past trough the installing part.
I am also having troubles with my wifi and i would like to fix it
Hello ! I don't remember exactly, I went on a website and selected the right version for my country ! But my problem wasn't solve at all actually... I brought my phone to the store, and they told me my motherboard was just burnt. They changed everything, and now it works like a charm ! Be careful with the custom kernel, I'm pretty sure that's how my phone broke (I'm very careful with batteries,...etc)
Well thanks anyway. I will try to take the phone to te oficial ASUS services from my country but i don´t think they give a new one. I live in Uruguay and this cellphone is not at sale over here
Does sideloading the firmware wipe your apps? Or is every thing still there when its done?

Hi, a friend have 2 pda universal from vodafone that he has flashed and killed. I don´t know what happend. pda always shows USB and v1.00. After a lots o rom updates still dead, i have JAFWM, but with or without this machine is dead.
any rom especial version?
any soft?
thanks.
1. Try to restart the device in bootloader mode(Light key, power and reset pressed together)
2. Look at the display (should say Serial and version at the bottom)
3. Disable the USB connection in Active Sync otherwise the update will crash.
4. Plug in USB Cable (Screen Should now show USB at the top)
5. Start original Upgrade from your provider or take the upgrade you want to use with the MA_UpGrade_noid.exe.
6. After Flashing restart device with both soft keys at the bottom of the screen ( Buttons with - on it) pressed.
7. When asked type 0 to erase all data.
9. Device should start normally, if it doesn't do not hesitate to ask.
device always start in bootloader mode, i flash all times without problems, but when i restart device, automatically puts on bootloader mode.
after flash, make factory settings but,after this, restart in same mode.
always, when i run update program soft MaUpgradeUt_noID, detects no rom in pocket loaded.
strange problem on 2 pda´s ?
thanks
That shouldn't be a problem. Just continue to flash the rom. There could be a problem with your bootloader and the upgrade version (AKU2) you want to use.
Maybe it's a problem with bootloader.
Try it, maybe it will help you.
http://forum.xda-developers.com/download.php?id=11414
i think same as you, only problem with ROM image, but i have flashed many roms but I can´t revive device. So i ask name of Rom tht can revive pda.
Br.
PD. how i can flash the archive attached?
The rar file mentioned above is only the bootloader you already got on your device.
In your case i would use an old AKU1 rom and to see if it works.
hi guys
i have same problem. show only boot loader mode. how to use this boot loader file. wich AKU1 file is working. my phone is MDA PRO from germany T-mobile, i wan't to update ro to English. after flashing many times, many rom no result. help me

Hello Siemens Man
Which Bootloader do you have ?
It would be great if you could make an backup of your bootloader then, that i could downgrade my phone and try to unlock it.(If do not know how to make an backup, thats no problem, because i can show you how to do it)
greetz
hi man

thanks a lot
Did you try to update your phone to the latest orange rom for testing yet ?
If not try it out (I know it is said to be slow, but only if all orange customizations are installed) If it runs then its ok.
Otherwise try to use the exitbl.exe mentioned somewhere in this forum, hopefully it works.
connect to mtty and issue set 14 0 and then restart the device or use exitbl utility by buzz

HI to all! I have lost bootloader upgrading my qtek 9000 vodafone.
can i to solve problem? No bootloader menu, i have tried power+reset+lamp, power+reset+camera - herd reset with - + - reset without effect. Pse help me!!! Thanks.
Hi!
What I have done:
-got a rom which fits to my needs
-downloaded it, renamed it to DIAMIMG.NBH, transfered it to my internal storage
-put the phone into bootloader mode, used MTTY all went well
-boot again... freeze
-initialising rom .... freeze
-trying custom_ruu.exe .. freezes at 0%
-hard reset.. fine, boot.. freeze
-finding the thread about MTYY reading that I should have Hard SPL.. swearing a lot
Is there any possibility to get my phone running again? As far as I have found no info how to install anything without a running sync connection, but without any system on the phone I dont know how to establish any connection other to the bootloader mode
Because you haven't upgraded HardSPL before flashing new custom rom - I think you did brick your phone.
Hello, prl3st
I have solition if you use htc touch diamond ( diam 100 ) but if you did not model HTC Diamond, can go try it.
A possible solution could be:
- Obtain a functional ROM (file that RUU_signed.nbh) interface CustomRUU.exe
- Connect the phone cable to the PC
- CustomRUU.exe starts and pass the first two screens where you wondered if you connected the device and that he give the order to enter in flash mode
- On smartphone: press volume down and reset simultaneously to get in the boot mode. Once you made that follows the instructions on screen.
Possibly if it fails the first step to obtain a version of HardSPL Diamond, copy the file there. Nbh and running ROMUpdateUtility.exe phone connected to PC and a loader.
It should work. Good luck and more attention next time.
yep worked fine with the original ROM from HTC!
Thanks to XDA developers and big thanks also to awran5 who gave me some privat support =D
hi,
After spending many time trying to root my storex tab 901 I bought in france (Already installed on 4.1.1 with google play), Iwas finnaly able to root it using adb and command line.
to do so:
- Download attached file
- Download from google SDK usb_adb_driver
- Go to your device parameters-> USB -> enable debbuging mode
- create a c:\root folder on your windows XP computer then Extract the zip file attached into it.
- Plugin your device to the computer, when prompted for driver, use google sdk USB_ADB_Driver
- When done, open a windows terminal command line
- type: c:
- type: cd \
- type: cd root
- type: cd rootkit
- type: go.cmd
If everything goes well, your tablet should reboot. you can try installing the free app from google store called "Root checker" to confirm your device is properly rooted.
Also, if you lost the original rom and live suite, here is the link to download the latest build from storex web site:
(I will post the link later when I find it)
JB 4.2.2
CAUTION: USE THIS ROM AS YOUR OWN RISK.......Be sure you have the official rom in case it is not working for you. It appears that even though you have the same tablet Reference, depending on when you buy it, hardware might be a bit different and most likely you will take the risk of having a unusable Touch screen or wifi...
I found out you can fully use your Ezee Tab 901 4.2.2
you can install rom from Manta MID 13.
You will be able to install the rom using Livesuite.
Gain:
- Android 4.2.2
- Root Access out of the box
- Play store installed.
Everything will be working
For the link type in google:
MID13 Android 4.2.2 Jelly Bean - Manta Multimedia Info
select google link called: manta.info.pl
select the link catshare or 4shared.
Start live suite 1.7, select the download img file, do a format when prompted. You done.
When the tablet restart, go to the parameter icon, and change language to French or english
Procedure on the Ezee tab 901 with livesuit:
- completly turn off the tablet, unplug cable
- start livesuite and select the downloaded image file
- keep the VOL- button pressed and plug the usb cable
- without releasing the VOL- button press the Power button 6 times.
- You should hear windows sound saying a USB device has been plugged
- if windows request it, install the driver from Livesuitefolder\usbdriver
- Livesuite should automatically start the flashing process.
- when prompted, "Format device" press YEs.
- When it s 100% you tablet should reboot.
Done.
Note: I did not invent anything, thanks to the good work of MANTA team members. I just found out this rom works on my tablet out of the box.
Hi,
Thanks for sharing these tips. I'm gonna try to update to 4.2.2, hoping this is going to fix some problems with this tablet.
I've been looking a lot for information about how to update ezee tab 901, so you did definitely a great work !
edit : iflash went well, but touch screen is not responding anymore. Any idea of how to solve it ?
Thanks.

Hi,
did you try going into recovery mode and factory reset? (shutdown tabel completely and keep press on volume+key then press power button)
in the menu, using vol+/- scroll down to wipe factory reset and validate by pressing the power key.
Let me know how it goes.
btw, are you sure your tablet is a Ezee tab 901 and not 971?
Cheers
Hi,
Yes I've got 901 and not 971 (written on the back of the device). I tried factory reset , but still the same problem. However, I flashed again with the original rom, and then touch screen went functional again but the wifi switch is kinda "broken" : it's impossible to turn on wifi from the Settings menu.
I returned the tablet where I bought it, seems there's a sort of material problem with it :/

Im sorry to hear that, i dont think something is broken, i had the same issue with a memup tablet, even though it was a same reference, some model had different hardware, sonlike you after testing multiple rom i had only touch s creen and no wifi ( wifi switch went back to off when i tried to turn it on) or on other rom, i had working wifi but no touch screen.
I hope they will replace your device...

Fast custom ROM 4.2.2 by TOxico for Ezee tab 901
Guys,
I manage to find a very fast and usable rom for our tablet: (THanks to Toxico.) this rom will change your life.
All information and download are in the thread here:
http://forum.xda-developers.com/show...php?p=42274265
It should basically work on any A13 device with livesuit (tested on my Ezee tab 901 and on my 704CET mem up)
This rom comes with no TS driver, but there is all explanation and download to install the needed driver.
note: you might loose the camera though. I encourage you to read the full thread before going further and flash your tablet.
If you want to know the driver used on your tablet, run a adb shell and type lsmod (You will have a list of loaded/used driver.)
Dont be scared, everything is written in the toxico's thread
My only advice, if you dont know how to use adb, do not try it, this is not that easy.
I hope this will help.
Best regards.
As usual do it at your own risk and even more: make sure you have the original rom... just in case

Hi, sorry i cant help you, it looks like the 971 is using a10 cpu, sôit can be different.
If you know what you are doing, u can try to backup your original firmware and test the solution i have provided from toxico in py post above. But there is no warranty it s going to work.
Any case, donnot forget google is your friend
Good luck
Unfornetly it seems google doens't like this tablet...
I'll see what I can do with some backups and all.
Thanks anyway!
hi2all
before post this thread i cheked all xda but anyone method did not help me
my problem is "scanning media files"
one day when i serfing inet my E975 has been rebooted
after load i got a first time boot start message
all data lost and phone ask me to set all setting from beginning
now i see alltime 'scanning media files'
I have tried the following: steps:
made hard resets - no effect
flashed using KDZ updater (E97510C_00, E97510a_00 E97510f_00) - no effect
used LGtool (selected recovery..inserted my IMEI and load) - no effect
and followed this http://forum.xda-developers.com/show....php?t=2010624
but problem haven't solved
always media scanning
cant try any ways like fleshing kernel, becose need fastboot mode
cant unlock fastboot, cos cant make root... anyone way to install root not work, cos no access to phone storage
someone told me i can try to do root with adb shell... but cant find how i can use this in my sutuation
I would be very thanksfull any help
i rly dont know what should i do next....
In the past I have a problem with media scanner message, always running in the background, although I had no problems about rebooting or soft-resets, it was only a message running in the background always. The way I solve it was to go into "almacenador de medios" (dont know in english, maybe something like "media store") in app manager, and then force stop, clean data and clean cache, reboot and after a first past again, all went ok. I suppose you continue with the message after reseting maybe because cache or dalvik cache is not clean.
Hope that help.

have you tried the lg pc suite?go to lg's site and download it and the connect your phone to pc in "pc suite" mode.then from there you can do an update or press the "emergency firmware recovery" under device menu.This will propably recover your phone.

anyone knows how i can made root without access rights to sd card?
ways like "frameroot.apk" and via bat file "currentroot.bat" - not worked (all those methods need access to sd card)
or maybe there are any commands on ADB to reset or fix sd card?
i'm rly sad with my problem....
what is the model of your phone and ROM?
did You try go back to stock rom with LGMobile Support Tool?
I have same problem but it occurs when I flash to E97510D ROM (my phone is F180K):
http://forum.xda-developers.com/showthread.php?t=2246867
when I want to fix it, I make emergency firmware recovery in LGMobile Support Tool (and factory reset after this).
Maybe your motherboard is giving up
no... every time I go back to stock ROM, its working fine

Hello,
So the good news is - apparently we can unlock Kirin 970 now. I did the hardware testpoint mode with the HCU Client and it worked just fine! I was replacing the battery anyway so I already had access to the motherboard. The question now is - what happened to LineageOS ROMs? Looks like they just deleted all of them.
Is there anybody out there with one of them on their HDD willing to share? Google cached website is showing two of them:
lineage-16.0-20210211-nightly-charlotte-signed.zip 2/11/21
lineage-16.0-20210204-nightly-charlotte-signed.zip 2/4/21
I'm gonna try to build a custom LineageOS 18.1 (Android 11) soon as well.
Thanks.

Ok so here was the process:
1) Backed up all my data from the device (CLT-L29)
2) Factory reset the device
3) I used Huawei Hisuite software to rollback as far (BACK) as I could. It actually let me downgrade to EMUI 8.
4) Installed HCU and DC Phoenix (timed 72 hour license for both was like 20 euro)
5) Installed NECESSARY drivers on my Windows 10 machine (HUAWEI USB COM 1.0) for the testpoint
6) I opened the phone (I wanted to replace the battery anyway). Unscrew a couple of screws and take a shield to get to the pad.
7) With the phone completely off, short the testpad to ground (I used tweezers) and plug in the USB cable while still shorting out that pad. (USB cable that is connected to your Windows machine that is). Your phone screen will stay completely OFF, but you should hear an USB "ding" sound in you windows machine. Go to the device manager and check for HUAWEI USB COM 1.0 (Your Port). If you don't see it it won't work.
8) Fire up HCU Client, check account, select "Fastboot/XLoader (Hisilicon only)" on phone connection mode.
9) Go to the "Fastboot/Xloader" tab and select CPU (for me Kirin970_T2_A8.1_V5) worked fine.
10) Click Read phone info button, you'll see a progress bar on the bottom, it should take like 2 minutes
11) If everything went fine you'll see a log on the right with your unlock code in it
12) You can unlock it from that software, select "Bootloader lock: unlock", and "Write bootloader code" I also selected "Erase Huawei ID" and click "Repair" button. It will be quick. And that's it!
Now, flashing a custom ROM was a pain. Apparently most of them REQUIRE EMUI 9.0.0.159 (159 is the KEY!). You must get the original firmware and flash it with DC Phoenix. After that the process went something like this...
1) Put the phone in fastboot/rescue mode (hold the volume down button wile inserting USB cable with the phone off)
2) Flash TWRP for charlotte with fastboot from your PC
3) Restart phone into RECOVERY (TWRP) mode
4) Sideload your rom.ZIP file (Lineage for example)
5) Sideload google apps
6) Sideload factory camera app (honestly its the best for that phone)
7) Restart the bootloader (you will be in the fastboot mode again)
8) Upload the ORIGINAL recovery image (it wont boot if you dont do it) you can revert to TWRP after the first boot
9) Go into Huawei recovery mode (power+volume up)
10) Wipe/factory reset
11) Restart and you are done! (now you can flash TWRP again if you want)
It took me an entire day of work to figure it out. All the info (steps) is available online including the location of the test pad and disassembly of the phone. Here's an awesome guide to flashing Lineage (https://depl0y.com/posts/P20-Pro-LineageOS-Guide/). One thing I've noticed if you try to use HiSuite AFTER you unlocked your bootloader it WILL lock it again. I had to do it twice while I was trying to get EMUI 9.0.0.159. The best way was to use DC Phoenix and ROM from androidhost.ru.
Anyway after all that I now have an unlocked P20 Pro with stock android. It's bloatware free and runs great. So far no major issues with the ROM.

Ok so here was the process:
1) Backed up all my data from the device (CLT-L29)
2) Factory reset the device
3) I used Huawei Hisuite software to rollback as far (BACK) as I could. It actually let me downgrade to EMUI 8.
4) Installed HCU and DC Phoenix (timed 72 hour license for both was like 20 euro)
5) Installed NECESSARY drivers on my Windows 10 machine (HUAWEI USB COM 1.0) for the testpoint
6) I opened the phone (I wanted to replace the battery anyway). Unscrew a couple of screws and take a shield to get to the pad.
7) With the phone completely off, short the testpad to ground (I used tweezers) and plug in the USB cable while still shorting out that pad. (USB cable that is connected to your Windows machine that is). Your phone screen will stay completely OFF, but you should hear an USB "ding" sound in you windows machine. Go to the device manager and check for HUAWEI USB COM 1.0 (Your Port). If you don't see it it won't work.
8) Fire up HCU Client, check account, select "Fastboot/XLoader (Hisilicon only)" on phone connection mode.
9) Go to the "Fastboot/Xloader" tab and select CPU (for me Kirin970_T2_A8.1_V5) worked fine.
10) Click Read phone info button, you'll see a progress bar on the bottom, it should take like 2 minutes
11) If everything went fine you'll see a log on the right with your unlock code in it
12) You can unlock it from that software, select "Bootloader lock: unlock", and "Write bootloader code" I also selected "Erase Huawei ID" and click "Repair" button. It will be quick. And that's it!
Now, flashing a custom ROM was a pain. Apparently most of them REQUIRE EMUI 9.0.0.159 (159 is the KEY!). You must get the original firmware and flash it with DC Phoenix. After that the process went something like this...
1) Put the phone in fastboot/rescue mode (hold the volume down button wile inserting USB cable with the phone off)
2) Flash TWRP for charlotte with fastboot from your PC
3) Restart phone into RECOVERY (TWRP) mode
4) Sideload your rom.ZIP file (Lineage for example)
5) Sideload google apps
6) Sideload factory camera app (honestly its the best for that phone)
7) Restart the bootloader (you will be in the fastboot mode again)
8) Upload the ORIGINAL recovery image (it wont boot if you dont do it) you can revert to TWRP after the first boot
9) Go into Huawei recovery mode (power+volume up)
10) Wipe/factory reset
11) Restart and you are done! (now you can flash TWRP again if you want)

Things are not that simple. The HiSuite on Mac have been updated.
I can't find the button that can roll back or check for update after this.
Maybe I should try HiSuite on Windows.
I suddenly remembered that I cannot use HiSuite Windows version to roll back to EMUI 8 , but I can roll back to EMUI 9. Maybe I can roll back to EMUI 8 from EMUI 9. Needing roll back twice ?

You *should be able to unlock it with EMUI 9. I rolled it back to 8, just to find out later on I need 9.0.0.159 anyway. So I used HiSuite to update it to 9 - but it wasn't the version I wanted and also doing this in HiSuite removed my bootloader code, so I ended up using HCU Client on EMUI 9 and it worked just fine. After that I used DC Phoenix to flash the 9.0.0.159 (bootloader stayed unlocked). It was a pain, but yeah you SHOULD be able to unlock it with EMUI9.

Here's a log from unlocking 9.0.0.168...
Just to let you know that official ROM (lineage-16.0-20210211-nightly-charlotte-signed.zip) is not working on my P20 Pro. It crashes on the first boot. I'm back with (lineage-16.0-20190217_125340-UNOFFICIAL-charlotte.zip) I believe it was made made by LuK1337. Works great. I use it with open gapps pico version.
guys, this is p20 non-pro forum.
why are you discussing this here?
