[Huawei MediaPad X2] audioralf:
Thank you for testing and reporting.

I guess you are on B111 now and to run the dload with the update.app, you have to flash the B112 files before.

Now I guess you had installed a different boot recovery on last trial. This might be the reason why the dload won't run, because it checks for the present files.

Try this: Install TWRP 5.1.1 and install universalcust for B112

Do a factory reset in TWRP

then goto you adb directory and delete the files boot.img, userdata.img, recovery.img and system.img. and if present cust.img.

then extract those files for B112 or download from here to your adb directory B112 files

Then flash boot,system, and recovery and try to start the dload via the vol- vol+ buttons.

If it runs into error on about 5 % flash userdata.img and try again.

If it runs into error repeat staring dload up to 4 times

If the dload process was successful, don't check the "about phone" info, but install TWRP and the universal cust B112.

Then do a nandroid and then install NearStock B111 the SimplyGoogle112

Yes you are correct, I was not able to remember what was the exact message.

It is normal that we get installation fail message on about 95%

Unfortunately the nadroid does not save the cust folder. So "untouched" means, that someone has just installed TWRP and not installed or flashed anything else.

Then he is able to copy the folder /cust with a root file explorer to the internal sd card and then zip it and send it to ajsmsg78.

If you once installed anything on your device the original cust folder will be lost for ever.

I had done this for my 701 model, which is delivered to west europe. So this device is supported.

The other points are possible things users have done by own inspiration and wondering why things didn't word

- renaming of files was wrong (in some guides we found the advice to rename TWRP_ENG_5_05.img to recovery.img and the run a batch file which flashes a "recovery.img"

This causes much confusion, because of the word "recovery". We have a partition on andriod wich is named "recovery". It can contain a program, wich has a name.

The files which are packed in the Huawei "update.app" which are named "recovery.img" are the Huawei_recovery applications for the recovery partition.

This is needed to do a firmware reset, to format the internal SD and to perform the "Dload" process.

But the recovery partition also can contain a different program. For example a version of the "TWRP".

This special recovery program also can be flashed via the command fastboot flash recovery XYZ.img, where XYZ.img is the name of the the TWRP.

The name must not be recovery.img but CAN be.

Some guys renamed it via the windows rename function with option to "hide known extensions". The result was recovery.img.img

Then they started the batch file which could not find recovery.img ;)

- not done reset on emui

- corrupt format of internal sd

I mean within EMUI we have the option to return to factory settings and there is a checkbox to format the internal SD.

In some situations users reported that the internal sd was 3 GByte instead 32 GByte.

- too slow external sd card

I used a old slow SD card and wondered why the dload process took more than one hour and was aborted

- installed the wrong recovery

you must always install the recovery for the version you want to flash or from the previous version.

B112 has 2 "previous" version B109 and B015

- had overwritten uni cust via flashing cust.img

Some guides say that you have to flash cust.img. But we replaced this step via installing universal cust via TWRP installing.

If you flash cust.img after that you are overwring some infomation which have been installed via the universal cust.zip file.

The difference is that this zip file also contains some script. So it can't be flashed simply as a cust.img.

- not supported version in universal cust

If your device is B006 there may be some hidden information of this in your device. The script inside the universal cust must modify this to get a full running coversion from B006 to B015

This is to get a manual update on other devices. It is not necessary for us , because we have the "dload" local update
