G750-U10 B113 continous boot-loop

My device from HU. G750-U10 version B113, stock ROM 4.2.2

Well I did not read all the forum as was quite long now I have a continous boot-loop. What I did.

1. Phone was rooted via RootGenius, as I i was using terminal and "SU" command seemed to be ok.

2. I did a complete backup using MTKDroid software.

3. I flash ONLY the recovery.img ( CWM ) - Yes I saw after the issue heappened do not use the MTKdroid software..

4. Reboot the phone now here is continous boot-loop, all I can do is enter in Fastboot&Rescue ( USB connected + VOL Down ), I also get the serial number from fastbook command so drivers are ok.

when I try to use "fastboot" command to re-flash recovery I get the same access denied. When I run "fastboot unlock UUUUUUUUUUUUU" phone ask me if I really want ot unlock I choose Yes but fails.

I read almsot all posts - I saw no cure. Can anyone lync me to a working solution keeping in mind that all I have on the phone is "Fastboot&Recovery".

Thank You.

UPDATE: I used "fastboot continue" and phone started. I started terminal on the phone and SU is working

I could update the recovery img from android terminal just I need the block where to.

UPDATE2: I run from android terminal the "flash_image recovery...... " and I got access denied. So seems the device in not rooted properly but as mentioned on terminal I can run SU, and apps get SU.

Using TotalCommander I changed the /system/bin folder permision to 777 ( write ) and it worked...

MTKDroid tool says that system/bin/su is missing but is there. ...

Some feddback for those who are new and plan to use Win8.1 - You might run into issue installink driver as the MTK driver for Windows is not digitally signed. Here I mean the one for "Fastboot&Recovery". It might be easier way to install the Huawei HISuite that contains the driver still is not digitally signed so better use Win7 PC.

For those new here, with G750-U10 ( I have B113 ) you can not unlock booloader ( root ) properly. Like many others I tried to get the unlock code from Huawei site, you can not as the ProductID will not appear to you.

Here is the oficial Huawei site for this: http://emui.huawei.com/plugin.php?id=unlock&mod=detail I had no digit to be displayd when entering ProductID.

If I get it correctly there are a posts saying you need to flash the real stock ROM from huawei as the "U-10" dos not exist and should be T00. Here is how to do it, is not easy and you need to read other past and maybe future posts: http://xdaforums.com/showpost.php?p=55497054&postcount=1768 I found not "repack" option with al the links attached to download the stock ROM and clear instructions ( at least not for me ). Be carefull if you miss this then you really brick your phone. I will try to fing a way to flash my recovery and hev the phone work normally after I restart it without the need to enter the Fastboot&Recovery - connect the phone to PC and use "fastboot continue" command in order to boot the phone.

If I find a way then I will make a post with links for newby here to make it easier as I am reading this forum since this morning and get only here.

Any support appreciated and many thanks for all the effort done so far by everyone.

just forthe record: I managed to flash back the stock recovery image, boot-loop is gone. I did it with SP_Flash_Tool_v5.1352.01 from here tahat contains all the images and drivers for stock not only the tool:

There is a DOC how to - read carefully, what is important you can choose to flash recovery only. you do not need to flash all. The DOC I think has an issue, says disconned USB cable, well keep phone powered off, on step 5 you need to power on in order to download and write the image otherwise it looks like you wait forever for the download....

I tried to flash all but says is not allowed for my region so is clear that diffrent version B10, T00, B113... B116 or whatever updates are made based on the rule in your country or area. EU, US, China..etc.. therefore some updates are not released or like the unlock code not set available for your device that you purchased locally - officiall distributor like I did..

Also just to mention the tool SP_Flash does not need root or so...

Just to mention again: All I wrote was already in the forum, just took me a full day, gratitude goes to all that revealed this. Thanks again.
