I read a lot here but I don't have all steps clear.

My exact model AGS-W09C331B251, untouched.

How to upgrade to EMUI8? Any guide?
[Miscellaneous Android Development] Da9L:
Im considering buying this cheap tablet, as it seems to be performing rather well for its price. But just to get things clear:

The AGS-L09 model is the one that comes with Oreo firmware ?

The AGS-W09 model is the one that comes with Nougat firmware ?

Is that correctly understood or is there more to it?
[Miscellaneous Android Development] peter_hun:
No it isnt correct. We bought a couple of ags-w09 tablets with Android 8 in Hungary for a project we already used these models. It was mandatory to use them rooted, so we send them back because dc-unlocker works only on android 7 firmwares. Even the service wasnt able to downgrade them.

Huawei Mediapad T3 10 reboot issue

Hello!

I have a Huawei Mediapad T3 10 AGS-W09 tablet but unfortunately it keeps rebooting itself mutliple times in a day even if there is no additional application is open.

I purchased it in 2017 (EU) and it was always used without SD and SIM card (it was on Wifi).

The issue is arise with and without charging.

I tried with Android 7.0 and 8.0 but the issue is the same.

It was never rooted or unlocked.

Could you help me what can be the issue?
[Miscellaneous Android Development] Majorian:
Still no official way to upgrade from Nougat to Oreo (EMUI 8). If you had an AGS-W09C100, you could try the 8.0.0.26 upgrade floating around in the net. It says it requires AGS-W09C100B285. Too bad B285 has not been pushed out by Huawei to end users, so without unlocking the bootloader you are out of luck, anyways. FF now shows Oreo firmwares for several areas, but they are only security updates and will not upgrade to Oreo from Nougat.
[Miscellaneous Android Development] Thanostsak:
I don't think that C100 has an emui 8 update yet.
[Miscellaneous Android Development] tidonoff:
hello.

is it possible to downgrade this tablet AGS-W09 from android 8.0 to 7.0 without root and no bootloader code?

AGS-L09 Android 8

I found a firmware android 8 for AGS-L09C185 (Middle East - Africa - Latin America version)... You think is possible install this on AGS-L09C100 (west europe version) ? Or there is an hardware difference?
[Miscellaneous Android Development] fr_jason:
Hey everyone, I got AGS-W09C100B285 working.

I unlocked my bootloader using DC-Unlocker, I paid the €4 for the credits.

I have flashed TWRP 3.2.1-0_14.01.2018

Using "ASSAYYED_KITCHEN_V1.82_STABLE" I edited the "boot.img" to remove encryption.

Then, in TWRP, I wiped each partition and flashed the necessary imgs, extracted from "UPDATE.APP", to their relavant paritions, replacing the stock "boot.img" with the modified version.

I am now on "AGS-W09C100B285 Firmware 7.0.0 r1 EMUI5.1" without encryption.

Rooted successfully with Magisk 20.4 in TWRP.

With an unlocked bootloader, TWRP and ROOT, how do I upgrade to Android 8?
[Miscellaneous Android Development] fr_jason:
That's an excellent question.

The only decent ROM I could find was "AGS-W09C100B285" but that's on Android 7.0

I've been looking on English, French, Chinese and Russian forums but all I find are the ROMs and they don't seem to be OTA's or even flashable to get from android 7 to 8.

Updating from the sdcard with UPDATE.APP in the dload folder didn't work for me, what I had to do was extract the imgs from UPDATE.APP and flash them one by one in TWRP, this gave me a working and fully functional AGS-W09C100B285.

However when I tried to do the same or similar with the Android 8.0 ROMs it seemed impossible because of course they failed using the sdcard method but also because the Android 8.0 doesn't have "boot.img" in its UPDATE.APP

I can't seem to find a concrete way to go from Android 7 to 8, anywhere, I'm starting to doubt if it even exists.

Somone posted about two AGS-W09 tablets having Android 8.0 but I think that was installed at the factory.
[Miscellaneous Android Development] Thanostsak:
I see many are asking about upgrading to android 8. These are the facts we know so far.

The devices with preinstalled android 8, are unfortunately not supported for bootloader unlocking (including third party service providers), so rooting and downgrading are not possible.

The devices with preinstalled android 7, can be unlocked (third party service provider like dc-unlocker) and rooted/decrypted but upgrading for most devices is not possible.

However, there is, in theory, a way to upgrade. Rebranding. This requires an oeminfo from a device that already has emui 8. For example an unlocked AGS-W09C100 (android 7) could use the oeminfo of an AGS-W09C432 (android 8) to upgrade and preserve the unlocked bootloader. The problem with this solution is that in order to extract the oeminfo from the device ,the bootloader needs to be unlocked. So we are back in the loophole.

The only way that i can think of is modifying the region of an existing oeminfo using something like this:

https://xdaforums.com/p9-plus/how-to/mod-oeminfo-structure-t3446382/amp/

I tried to give this a go but I was not able to repack the oeminfo file with the modified region.

I've done this on some Samsung devices with odin and TWRP(galaxy s7 installed Lineage 17.1)

It seems to be not so easy on this device....

So i downloadet CDunlocker and try to unlock it. ATM the DCunlocker dont detects my tablet....do u have any advice?

Do u have any guides orr tips to install a custom rom on it?

Wich software do u use to flash TWRP?
[Miscellaneous Android Development] Thanostsak:
There are no custom roms for this device.

oeminfo backup

Can anyone share with me your "oeminfo" partition of a AGS-W09, any help will be apreciated. Thanks

---------- Post added at 08:14 PM ---------- Previous post was at 08:05 PM ----------

Hello friend, could you share with me an "oeminfo" partition back up of your device... im actually semi-bricked with a "generic_a53" model number and no SN showing in the device info. it will help me to restore my device. thanks in advance.
[Miscellaneous Android Development] fr_jason:
Can you give me detailed instructions on how to perform the OEM backup?
[Miscellaneous Android Development] randrew87:
Connect your device to the computer, type adb shell in command line console or TWRP terminal.

Now type dd if=/dev/block/platrofm/hi_mci.0/by-name/oeminfo of=/sdcard/oeminfo.img and you'll get a byte-to-byte copy of oeminfo partition in internal storage.

many thanks in advance.

I've just got an ex-retail demo model. I've been able to unlock with dc-unlocker and HiSuite found, downloaded and installed a 2018 ROM.

I've a few issues:

default sleep is 15 seconds, I set to 2 mins and it doesn't change, it still says 15 seconds

There was an app called retail demo which I've removed soI can move icons around, but i still can't change the inactivity time

I have setup and account and that is still configured.

Does anyone know how I can stop this reseting of appearance?

thanks

I found an alternative settings app by gabenative on the play store which allowed me to change the time to 2 mins and it works! :fingers-crossed:

Ok, so there are a load of official full OTA out there but does anyone know what the latest is for an AGS-W09C101? The one HiSuite put on is B271 which has security for 1st Aug 2018.

thanks

Paul
[Miscellaneous Android Development] t3rm3y:
HiPaul,

How did you go about unlocking the tablet with dc-unlocker? i have never used this before, seems i would have to purchase credits? do you have the steps you had to do please? (or a link to the post on this thread).

im also on the B271 software, how did you get newer?

I only want to be able to move games from internal to sd card..
[Miscellaneous Android Development] csjjpm:
On the DC Unlocker website there are 'text tutorials' and follow the one for 'tablets', it goes like this:

Turn on phone.

Connect it to computer via USB cable.

Wait till all drivers are fully installed and phone appears in "Modems" and "Ports" sections in Device Manager.

Then launch DC-Unlocker.

Open Server tab, enter username and password that you received after credits purchase (you can buy credits here: www.dc-unlocker.com/buy ) and click "Check login"

If DC-Unlocker/Vygis/Rocker/Infinity dongle is connected, do not enter username and password, only click "Check login".

Select Manufacturer: Huawei phones, model leave Auto detect(recommended).

Click on "Detect" button (big magnifying glass).

Wait till phone will be fully detected.

Open Unlock tab, click "Unlock".

When you see that phone is successfully unlocked, remove battery and restart phone.

I registered and account and bought credit, Euros 15, I put my tablet in fastboot mode and DC Unlocker found it.

Then ran the software and it removed FRP.

I don't have newer than B271 as I've got model C101 and B271 is the newest for it. There are some sites which list the variants and what the latest 'update.app' is. I put some in a dload folder and tried to update but it said they weren't designed for my model. You need to check what variant you have.
[Miscellaneous Android Development] peter_hun:
Your "help" doenst make any sense. First, you have to buy only 4 credits to read bootloader unlock code, you dont need to remove FRP unless it is a stolen tablet...
[Miscellaneous Android Development] Crisal:
Hi, I have a MediaTab T3 ags-l09 I have root root on tablet and bootloader unlocked including FRP, I have performed a factory reset from the settings and now the tablet goes into recoveri twrp and when I start it starts in huawei eRecovery, if I try to install the firmware from TWRP everything that flasho tells me is impossible to mount usbotg (no such device) or from sideload from error 9.

I can no longer log into the system, the Huawei logo starts, stays a while and then restarts.

How can I solve it?
[Miscellaneous Android Development] dhomas:
To unlock the bootloader, you'll need to first purchase 4 credits (4 euro) from dc-unlocker. Then follow these instructions, paying special attention on how to enter Manufacturer Mode via the calculator app (since the pad has no dialer app):

Android 8.0 ROMs have the bootloader as the "aboot.img".
[Miscellaneous Android Development] fr_jason:
At that point in time I did all the necessary modifications on the aboot.img as I would on a boot.img but to no avail.
[Miscellaneous Android Development] futurestar10:
Hey guys I REALLY need some help here! Please! Ugh I'm such an idiot.

This might be long to read through but please read it!!!

So it all started after I tried to uninstall magisk through the magisk manager app. It did uninstall magisk but it got me into a bootloop.

Now like the idiot I am, by mistake, in twrp I had wiped the whole OS, system partition and stuff.

So then my only option to get back to stock ROM was to use fastboot and flash the factory images such as "boot.img" "system.img", now I can boot into an OS and have the apps by huawei. But there's no google apps!

There's no google play services,no google account manager, no play store, nothing except the apps that came with flashing system.img.

I tried manually installing google play services by using a browser to install the APKs but it causes bootloop. I tried flashing open Gapps (arm64,android 7.0, pico) using twrp, it flashed successfully, but caused a bootloop.

I tried huawei firmware finder and tried using the DNS method to get an update through erecovery but the erecovery fails to find info.

I tried the dload method by putting UPDATE.APP in dload folder in the SD card and then did the relevant step, but that doesn't work either.

Is there no way I can get back to my stock ROM? I downloaded the stock ROM for AGS-L09 from the 1st post.

Please help...

Note: There's also no themes in the themes app.

Unlocked Mediapad, problem with TWRP

I've tried the procedure (indeed a lot of procedures) my tablet is boot unlocked (did it with DC Unlocker)

Now I'm trying to flash TWRP on recovery but is not working...

When I boot in recovery mode ( Vol + & Power on) the system start and the go in black sceen,

I've tryed a lot of revision of TWRD no success.

Any suggestion?

Thanks a lot

[Miscellaneous Android Development] cor85:
My Mediapad T3 10 (Wifi only) started cyclic reboot last month. I've tried factory resetting using various combinations of Power,Vol Down & Vol Up.

Using an SD card I've tried several versions of firmware from http://huawei-firmware.com/rom/huawei-mediapad-t3-10/ags-w09. Extracting s/w to /update on the sd card. They usually fail with "Software install failed!".

Huawei eRecovery download recovery also fails during "getting package info from server" with "getting package info failed".

The mediapad came from Amazon UK and has model number 53018635 .

The tablet was never rooted or had any modifications. Now if rebooted it just keeps rebooting until the battery runs out. I get the Huawei logo, then bubbles, then another reboot.

Any suggestion?

thanks

Yes but you need to change country/region for hw/eu or some place with the official 8.0 update.
[Miscellaneous Android Development] i_am_fresco:
TWRP works with 7.0 firmwares. Maybe you are in android 8.0.
[Miscellaneous Android Development] i_am_fresco:
It happens when you unlock your bootloader or replace some hardware part (commonly LCD screen). Try to flash with a Qualcomm firmware package via EDL/Q9008 mode.
[Miscellaneous Android Development] i_am_fresco:
With TWRP if you can unlock the bootloader, if not, you need open the tablet, make a test point short, connect in Q9008 mode and using QFIL you can make the partition backup. If you need a guide just tell me.
[Miscellaneous Android Development] fr_jason:
How do we go about doing this?

Do we just change language/region from Settings and that will be the region change that allows us to upgrade to 8.0?

Or is there another method we can use so we can flash a full 8.0 firmware?
[Miscellaneous Android Development] cor85:
Success at last!

So I've been attempting to recover a device which was stuck in a boot loop. This boot loop happened spontaneously, I assume after a failed upgrade. There was no rooting or any modifications to the device.

Everything I tried failed. The best I got was to 5% upgrade and then failed. I tried multiple versions of firmware which I extracted to UPDATE.APP and put into a dload folder on a memory card. See first post on this thread. This thread is useful but very long dealing with different issues so I didn't read all the thread so hopefully this advice wasn't already given. If so I've wasted a lot of time.

I downloaded from Huawei and from this thread but each time there was no SDUpdate_Package in extracted file. Certainly not in any of the AGS-W09 files.

Finally, I googled and found Russian firmware at https://androidhost.ru/a1W

I extracted this, then extracted the SDUpdate_Package and copyingt he dload folder to the SD card and rebooted holding the three buttons down. This worked.

Now as I have no idea regarding the s/w, I've connected the device only to the Guest network at home and plan to keep the device isolated. It is only used for browsing.
[Miscellaneous Android Development] fr_jason:
I'm in the same boat as you.

Got stuck when trying to go from AGS-W09C100B285, to an AGS-W09C233 firmware.

For whatever reason now, FRP is locked but luckily my bootloader remains unlocked.

Team MT's Multi-tool 8 says it still has C100B285.

No solutions, fastboot or hex editing has worked thus far.

I'm going to try the firmware you suggested, maybe I'll have some luck.

@cor85 did your SD card have to be in any particular format?

So far I have tried; FAT, exFAT, EXT4 and just now NTFS.

None seem to work, I still get stuck at 5% and then eventually it gets reboots again to get stuck again at the boot screen.

I have FRP lock now, can't boot at all, can still acess TWRP and fastboot but with this FRP lock, can't do anything.
[Miscellaneous Android Development] cor85:
FAT32

So extracted the file which I downloaded resulting in SDUpdate_Package.tar which I extracted ending up with a dload directory under Software.

In dload directory there was UPDATE.APP and a folder AGS-W09_hw_eu which contained update_AGS_W09_hw_eu.app.

so a dir from the pc

Directory of C:\Huawei\Huawei MediaPad T3 10 hw eu AGS-W09C100B278CUSTC100D001 Firmware 7.0.0 r1 EMUI5.1 05014LUG\Software\dload

20/01/2021 09:57 <DIR> .

20/01/2021 09:57 <DIR> ..

08/10/2018 08:47 4,023,586,860 UPDATE.APP

I copied dload (all of it) directly to the SD card. Held down Vol+ Vol- and Power and once restarting I let go of power and then it started the install. I was expecting it to stop at 5% like before but it kept going. After 100% it looked to be hung but I left it and eventually it started.

I'm in Ireland but this tablet was purchased from Amazon.co.uk.
[Miscellaneous Android Development] fr_jason:
Thanks mate, I'll try that now.

The SD card I had couldn't be formatted in any way to FAT32.

I found another, an old one, takes 15mins to copy the dload folder.

Will report back here with my findings.
[Miscellaneous Android Development] fr_jason:
@cor85

So FAT32 SD CARD with "dload" folder with "UPDATE.APP" and " AGS-W09_hw_eu".

Best I got was stuck at 5%.
[Miscellaneous Android Development] fr_jason:
I guess I'll start with a fresh cry for help;

I have the Huawei MediaPad T3 10 aka AGS-W09 on firmware AGS-W09C100B285.

I cannot boot to System.

Booting into eRecovery does allow Wi-FI connection but cannot seem to retrieve package info.

Fastboot & Rescue Mode shows PHONE Unlocked and FRP Locked.

I have since attempted flashing via SD Card through 3-button boot, on multiple SD Cards, correctly formatted in FAT32 and with the necessary "dload" folder and subsequent contents.

Does anyone have any advice on how to proceed?
[Miscellaneous Android Development] khil:
I have the same problem and begin to think it really depends what you did to it before.

I use DC-unlock paid code to unlock BL, then flashed the apropriate english TWRP, then just magisked it.

Now I updated magisk and the tablet started acting weird, did a full factory reset, which was unsuccesful (screen lock PIN stay, despite reset, for example) so I did wipe inTWRP, accidentally checkin too many options and wiped the OS completely :D.

Now I managed to find/remember my version, L09C100B279, flashed back the apropriate original recovery. And now as many others the stock recovery wont flash any UPDATE.APP, i.e. stops after 5%.

Relocking BL seems risky, as possible wont be able to unlock it again and there is no guarantee HISENSE recovery will work. I am out of ideas, there are no custom ROMs.

EDIT:

wait wait wait, the russian did it again, i stupidly searched the androidhost.ru for my version C100B279 and found 2 roms emui 5.0 and 5.1. Just flashed 5.0 and it went over 5%. It runs smoothly. Obviously set up a fresh gmail account for this, and wont use it for anything personal related.

[Miscellaneous Android Development] fr_jason:
At the moment, I can access TWRP and fastboot.

However I can't do anything from fastboot because I messed up something and FRP locked myself out.

And I'm not sure what to do from the TWRP side as long as my FRP lock remains.

I think I'm bricked at this point.
