do you put dload folder in root of sd card ?

Force upgrade already works. But it only shows a pink bar without text. I wouldn't know if it's unpacking or installing. Now, my problem is that I think that I'm stuck at unpacking even if there's no text because it stopped loading.

I have a question: Can I flash a stock recovery through UPDATE.APP? Only the stock recovery.

I already have a stock recovery.img, but I can't flash it through fastboot because of the locked bootloader...

Yeah, I know. I tried contacting Huawei and requested an update.app for V100R001C000B182. But they kept telling me to let it checked from a local Huawei store, which there isn't.

Is there another place where I can download an update.app?

B182 is the build version for the Middle East Channel.

Hack tool a real problem. He wiped the IMEI but sometimes do not make the correct Beckup. I made Beckup but can not return it. Or I may have accidentally done Beckup IMEI 0. Try to put it HUAWEI_Y300_firmware%28Y300-0100%2CAndroid%204.1%2CEmotion_UI%2CV100R001C00B175%2CNormal%2C05011FKA%29. Works but no IMEI. good luck

sry update firmware Y300-0100_Android_4.1_Emotion_UI_V100R001C00B175_Normal_05011FKA

What do you mean by "Try to put it HUAWEI_Y300_firmware%28Y300-0100%2CAndroid%204.1%2CEmotion_UI%2CV100R001C00B175%2CNormal%2C05011FKA%29"?

If you are having trouble restoring your IMEI, try putting the OEMINFO-BACKUP to /sdcard or /storage/sdcard0 since /sdcard and /storage/sdcard0 are both internal storage.

Huawei Ascend Y300 Unlock & Root [How To / Tutorial]

This great little Android 4.1 smartphone has been released to the German market a week ago. At a price tag of merely 150,00 Euro, it's a steal.

But no fun without root, right ?

Now, Huawei locks and secures the bootloader, which makes flashing a custom recovery impossible without messing with the bootloader code itself.

Luckily, i found out that you can request a bootloader unlock-token on the Chinese Huawei website. After unlocking with

Code:

fastboot oem unlock XXX16-digits-codeXXX

we can flash a china-made (aka chinese-language only) ClockworkMod v6.1, that has been compiled for the Y300. After installing SuperSU from CMW, you GOT ROOT.

I have written an extensive dummy-style tutorial on my tumblr blog. Unfortunately, the forum wont let me post outside links. Please go to this URL:

huawei-y300.tumblr.com

Have fun!

Can u give me system update app of your phone? I need Update system from sd card feature

Hi guys!
Week ago I bought Ascend Y300 locker to Croatia T-Mobile network. As you guess, it's branded (startup i shutdown T-Mobile logo, T-Mobile ringtones ect.).
I requested code for unlock bootloader from huawei and this morning code arrived

Version of software is: Y300-0100V100R001HRVC150B151
I need few answers.
If I flash mobile with official Huawei rom (http://www.huaweidevice.com/worldwi...=toDownloadFile&flay=software&softid=NDcxNDI=) will I loose Croatian language? Do I need unlock bootloader first for flashing this official rom?
Last question

I ordered sim unlock code for unlocking so I can use Croatian Vipnet network. Can I unlock phone with this code after putting original non branded firmware or I must do this before?
Tnx in advance.
----------------
EDIT:
I put sim card which phone did not accept and enter sim unlock code and voila! Phone is unlocked

Next I tried to put original firmware but none of methods wont work (forced update with fastboot turned off - normal upgrade from update option in phone). Starts unpacking and when showed installing just shows yellow triangle with message ˝update failed˝.
Any solution for this? I did not unlock bootloader since I wont install custom firmware (for now

).

I tried to restore oem info because my imei is blank, but cmd says that there is nos oem-info on my mem card but it exist as you can see in pictures.

and here

AndronoobS3 · Jun 15, 2013

I think that I restore my IMEI. I put phone transfer to MPT and started restore oeminfo and it showed that operation is done. When phone reboots it shows Huawei logo which has been before when T-Mobile rom was in it but it cannot boots because that inside is stock Huawei rom which I didnt manage to install with my IMEI. Now my phone has my original IMEI but stock Huawei rom and cannot boot. I tried to force download again stock rom but it not allow (yellow triangle after unpacking).
Is there any T-Mobile rom so I can restore my phone?
EDIT:
Phone boots normally after I cleared cache in TWRP

I put my sim card and everything works so original Huawei rom stays. Only notification bar missing but I wont touch anything because i two days I lost few years of life finding solution

You should've done a full backup before hacking your imei so that after you flashed the original firmware, you can restore to your branded firmware.

It's always important to make backups.

You can add mods for the notification bar. You can find it here: http://www.android-hilfe.de/root-custom-roms-modding-fuer-huawei-ascend-y300/

The mod is for o2 devices, maybe it'll work. Do this only at your own risk.

This mod not work for me. I will waiting to someone make possible to install original rom without touching imei. Ofcourse and Huawei must fix problems with notification bar in their rom.
I know that backup is most important but I was too quick and now I pay my stupidness

Even though you'll revert back to stock, there still wouldn't be a notification panel unless you'll install the vendor folder included with the dload folder. But if you want to revert back to stock, you'll have to backup and hack your imei then flash the dload folder. Then install a mod for the notification panel through TWRP.
