locked bootoloader

Hi guys

First i would like to say hallo to everyone cause iam new here. So ''Hello''.

Iam the owner of Huawey Y300-0100 and iam wondering is there any way to change bootloader satsu back to ''locked''.

I now I can change to ''relock'' or something like that, but I really need to have ''locked''.

Sorry if the answer is somewhere on the forum but I couldnt find it.

Thank You

Need a little help with this guide!!!

Seems like this post is no more getting replies but i will try my luck. Also i am noob at rooting so please try to explain things in simple words. There couple of things i wanted to ask and didn't understand in the guide.

First of all will rooting my phone void my warranty. I have Y300-0100 one version. If it will void my warranty can i unroot it so that when i need to update or flash my custom rom i can do so.

Secondly where is the root of the SD card? And when i boot my phone in safe mode as mentioned in step 3 how will the update happen? Will it happen automatically or do i need to trigger it from somewhere. And you said that if we get pink screen we need to put the "dload" folder in the root of the internal memory. Where is the root of internal memory? And to put the folder in the internal memory do i need to open the phone in normal mode and use file manager to put it in the internal memory?

Thirdly you said in the step 6 that to install drivers. From where can i install these drivers? do i install them from the phone or the rar file you provided?

Fourthly how can i backup my stock rom so that i can restore it if somethings bad happen.

Fifthly i don't know if i am allowed to ask this or not so please forgive me and dont reply to this question if this isnt allowed, but to install modded apps do i need to root my phone or can i just install them without rooting?

Sixth i want to ask that can any one here suggest me a good backup app that back ups app data,not only the apk file but also the save game, settings and extra files which are downloaded within the app.

Lastly you said if we get error like camera, flash or bleached screen we should run install-windows.bat, from where can i run this, from the phone or the windows?

Thanks for reading and thanks in advance for any help. Hoping for a fast and satisfactory answer. Many many thanks and if all of this cant be answered can i ask this in a new thread in reference to this one?
[Upgrading, Modifying and Unlocking] goku1234567890:
How did you run the install-windows.bat? I mean did you connect your phone with the data cable to the PC and then run the install-windows.bat from the PC or copied the install-windows.bat to the phone and then run it?

Hi, after following all the steps in the instructions and what seemed to be a successfully process, I had to reboot my phone and now it is stuck in the Huawei logo, how can I fix this?

I still cannot remove these progams.

Ik know it is a while ago this post but I hope to get an answer anyway.

I have rooted succesfully (I think).

I had the same issues with camera, but not anymore.

Now I want to delete these programs but how?

If I go to the app-info I cannot delete them. I can shut them down but there is no delete button.

Starting the SU appm there are no applications in the list.

With info it sasys I have 'outdated binary' tap to check for updates. But it failes on downloading the manifest.

And if I try again the SU app stops with error.

Does this mean it is not correctly rooted?

[Upgrading, Modifying and Unlocking] 0xmilan:
Hi!

The bootloader unlock code is different for everyone, there is no universal code that works for every phone.

Try to get into recovery mode with holding down the Volume Up button while turning the phone on. In the recovery menu do a factory reset and delete cache, it might solve your problem.

You can also install a stock ROM from Huawei. Check their official site for ROMs, that have a higher version number, than the one on your phone. Put the downloaded ROM into a folder named dload in the root of your SD card, then install it by holding down the Volume Up AND Down buttons while turning it on.

I guess that's all I can help with.

Cheers.

huawei ascend y300 in loop

hello, i know that code is one for only phone...i have tried many times to delete cache memory and restart/reset like factory.

i can go in recovery mode but after i have delete cache and reset restart the phone , logo of huawey appear on screen and donìt go away...it appear to be in loop....

i have also tried to install a original rom from huawei center but when i push volume up and down and power the phone say to me: that impossible to upgrade the phone the memory eecm is only in read mode, ...so i guess i must unlock the bootloader, and after install a recovery mode so i can try to installa new cooked rom...like cyanogenmod and so on...but without a code is impossible to do that....
[Upgrading, Modifying and Unlocking] adeii:
Mostly you got 2 options - to get unlock code from Huawei's site or to overwrite/flash bootloader partition from SD card and then install CWM or TWRP recovery.

1. I used this webpage, for mine Y300..but official site it not working now :( .... this one works!!! But since you can not boot and read Product ID.... use 2. option

2. You can uses this thread, it also works for Y300.

Good luck with unlocking/rooting!

---------- Post added at 10:46 AM ---------- Previous post was at 10:38 AM ----------

(Unofficial) SlimKat 9.0 for Y300 is also excellent choice!
[Upgrading, Modifying and Unlocking] buzz71:
yes, but i must to unlock the bootloader before..to that!

the phone now is hard brick!
[Upgrading, Modifying and Unlocking] adeii:
Had you tried second option, it works on locked bootloader?

You want to say there is no even bootloader / recovery mode work, when you said "hard brick"? Any illumination of navigation buttons or screen backlight?

Update!

Try this option http://huaweinews.com/2013/07/root-huawei-ascend-y300/ with coping dload folder to SD card and starting bricked Y300 in Downloader mode! It should overwrite locked bootloader. After that can you start phone in normal mode (and continue with unlockroot3.exe) or flash CWM/TWPR recovery?
[Upgrading, Modifying and Unlocking] adeii:
IMHO, apps in /system/apps can not be normally uninstalled, you need app like System App Uninstaller or System App Remover...
[Upgrading, Modifying and Unlocking] buzz71:
Y300 bricked...

HELLO THERE'S SOME NEWS...i have the bootloader unlock code form huawei home page...i have so, 16 numbers!

i have tried many times to use this code to unlock in ms dos with app to unlock the bootloader..it doesn't works...i can't unlock the phone. after i have tried to unlock , i check the unlock by this software (now i have forget the name..) and it isn't unlocked....

on the other hand i have tried to upgrade from sd with "download mode" but it do not works...it says to me something about "emmc" that work onlyin download mode...

when i switch on the phone i see the light, and vibration, but i can't see recovery mode...i see the light and animation on the screen but it remain on the android logo freezed....

sorry for my bad english.

i hope you have understand my bad language...:eek:
[Upgrading, Modifying and Unlocking] adeii:
How you failed with dload method?! Did you got "a green tick" after its done or not? After that you still can not boot in normal mode?

Can you go to (fast)boot mode by holding Volume DOWN button and turn the phone on while keeping the Volume DOWN button pressed for at least 10 seconds ?!

Your phone should freeze on the splash screen (fastboot mode). If you can, try to execute UnlockTools/check_bootloader.bat ? And that unlock_bootloader.bat ? Or even flash_recovery.bat ?

---------- Post added at 01:01 PM ---------- Previous post was at 12:52 PM ----------

At least, you can try to restore all stock/official ROM partitions (boot/recovery/system) and see if your phone is working or has physical damage. http://consumer.huawei.com/en/search/index.htm?keywords=y300

Hi,

In my telephone trying the dload upgrade mode I got every time "EMMC is readonly....").

My internal memory is readonly, the telephone is not usable , app crash cyclically and has many restart.

By means DC unlocker is not possible to get Bootloader code, the driver see the telephone as "device unknow" and the pink screen doesn't remain on screen.

I am no able to reach sites to get bootloade code online.

Someone can help me?

Can someone help

I tried to unlock my bootloader by using the dload method. (place dload in the root and reboot to update)

Now i get the image signature verify fail message

The problem is that i placed the dload on the internal storage and now have no way to remove it ?

I can only press volume up +volume down and power to load. the up and power doesnt work nor does down and power.

I tried to put a proper dload on the external sd card and flash that however it seems to be picking up the internal one..

Is there anything I can do to mount the internal storage and delete the dload from there?

Thanks in advance.
[Upgrading, Modifying and Unlocking] adeii:
Have you tried with ADB ? (Basicilly you need only adb.exe, fastboot.exe, AdbWinApi.dll and AdbWinUsbApi.dll in any folder and type following commands in command shell, put your Y300 in recovery mode... and mount all sdcard/sdcard0/sdcard1 or internal_sd if you can in stock recovery)

adb devices (just to see are you Y300 is detected)

adb shell (to start Y300 shell)

su (this can be problem, since you got not root)

mount -o rw,remount -t yaffs2 /dev/block/mmcblk0p19 /internal_sd

cd dload

ls

rm *

cd ..

rmdir dload

and if you removed dload folder from internal sd, and you copied dload folder to external sd, reboot Y300 to download mode (vol - and vol + and power) to update it.
[Upgrading, Modifying and Unlocking] eezergeezer:
Adb is not finding my device. Its currently at the image signature verify fail screen.

I can see fastboot when i run

fastboot.exe devices

I am able to reboot the phone using this. Any ideas please?

C:\Users\Downloads\sdk-tools\sdk-tools>fastboot.exe devices

917e155c fastboot <-- this is my device serial..

What can I do ?
[Upgrading, Modifying and Unlocking] eezergeezer:
To add to above comment. I cannot put the phone into recovery mode.. Only fastboot mode.. I can see the device in fastboot
[Upgrading, Modifying and Unlocking] adeii:
But you must have put phone in download mode also, to update with dload folder from sdcard. Have you already copied dload to external sd?
[Upgrading, Modifying and Unlocking] eezergeezer:
the dload is on the internal storage .. I cannot remove it.. when i try and upload the one from my sd card the phone picks up the internal dload folder.

the phone is rooted

the boot loader is locked

i cannot see the phone in adb devices

i can see the phone in fastboot devices.

I can only go to fastboot mode.

The camera fix isn't working, I tried running the bat file from both my computer and phone, neither worked...

Edit

: Actually, it's fine now. I hadn't run the adb-windows file. After running, it seems to have worked...
[Upgrading, Modifying and Unlocking] adeii:
Use some memory card reader/writter to copy dload folder from pc to sdcard and flash it or try this . You can not have rooted phone with locked bootloader?!

In fastboot mode, you can use commands:

fastboot devices,

and

and fastboot reboot

Here is mine images for download, bootloader is for SlimKat 9.0 and recovery is Clockworkmod 6.0.5.0.
[Upgrading, Modifying and Unlocking] eezergeezer:
So I finally managed to get this problem sorted.

This is how:

1: Get hold of the product ID. This is difficult as I couldnt boot into the phone. only fastboot mode

So I used a tool called:

Huawei Product ID generator

http://androidxda.com/unlock-bootloader-of-huawei-honor-7

This allows you to put in the IMEI and give you a product ID

2: go to the following huawei site and plug in the usual details

SN

IMEI

Product ID from prev step

The unlock code magically appears

3: install the correct ADB drivers and when your phone has the image signature verify fail message you should be able to see the device by entering the following command

fastboot.exe devices

run the following command and replace the XX with you unlock code

fastboot.exe oem unlock 1702426194789013

This will then allow the bootloader to be unlocked . U can then flash whatever recovery you want and finish the job

Bro, I haven't seen it because i just now started messing, just a few minutes ago, with this phone but one thing I can tell you.

ALL THOSE TYPE OF USELESS SOFTWARE FLAG THIS THINGS AS HARMFUL. WHY?

Because it could be, if the source isn't trustworthy AND malicious, the person using it thinks Google invented the internet, and/or both of the above.

Are you from the States? Because i don't know how it is where you're from, but here you can buy a hot beverage, burn your mouth, and sue and win because it was hot and there was no warning! (Now there is)

True story.

Therefore, antiviruses have always worked like that, because you're basically gaining access thru an exploit. But it's your phone and your access and your exploit so the warning is moot!

You only need common (more like "rare" nowadays) sense and you'll be fine

[Upgrading, Modifying and Unlocking] Jampony:
I got it too. It turns out I needed to put the folder into the INTERNAL memory, not the SD Card root.

idk if people who put it in SD Card root had SD card storage set as default, cause I didn't, but putting it in the Internal root did it for me.

I think OP should tell people to put the folder in both Internal and SD root, just to be sure.

Also maybe he could just direct people to download Unlock Root from the official website: unlockroot[.]com

As it's a few versions ahead now (3.1.1) and supports a lot more phones/seems quicker overall.
