[PATCH] Get back your PINK screen!
- Thread starter Blefish
- Start date
My burning question (and I think others have the same question)... with this "fix" for the pink screen / bootloader lock now available, what official rom version is the best to use for upgrading to the .35 kernel?
Or are they all the same, if you're going to simply flash a custom rom 5 minutes later?

b517 or b518, because then you dont have to unlock the bootloader
. Its faster. But i dont think it matter any other way.
Decided to go with B526 as I hope the latest version has less likelihood of losing the IMEI...lol Huawei is crap.b517 or b518, because then you dont have to unlock the bootloader
Anyway, I now have a phone running B526 + root + CWM + unlocked bootloader + a full backup (via Ghost, dd on Windows is not fun!)
I am not afraid of loosing my imei, i am afraid of killing my bootloader

It works with b528. I'm not 100% sure zip works but it just runs same command so it should work.

When you install B138, it automatically installs B138 bootloader.

Thanks!
So if you don't have a locked bootloader a new bootloader is always installed when you upgrade/downgrade stock rom?
My experience has shown that yes, all stock ROMs seem to install bootloader from the same version.
The bootloader is simply a binary, it hasn't got any locks and security on it, unlike in HTC phones.
But once we install the stock ROMs that have a locked bootloader, it stays locked no matter what other stock ROM we install, correct?

The work "locked" is not really right in our phone. It's not locked, it's simply modified "pink screen". Every stock ROM has a bootloader packed on, and will be installed when flashing. So it doesn't matter which rom you install, you will get bootloader from the same version as the rom you're flashing (B526 --> B526 bootloader; B138 --> B138 bootloader).
I hope you get me now

Oh I get it now... I was confusing the locked part with the no USB access in pink mode... so my question is, once we install a stock that has no USB access to pink mode, then, no matter what other stock we install, even 2.2, it will still have no access to pink mode, correct? At least that's my experience, and that's why this thread is so great, it provided me with a way to restore that USB storage...

56In the newer official ROMs, Huawei included a "feature" to lock the bootloader and therefore, get less bricks. But happened the opposite - if your cust partition gets corrupted/deleted, you'll have a high change of bricking your device.
The new bootloader is not actually locked, it's changed to use QPST (Qualcomm Product & Support Tools). As it needs a code, we can't use it.
This method flashes the B518 bootloader straight to your phone, so you will get back USB.
Apply only if you have upgraded your phone to B522 or newer. You may have a custom ROM on top, but the base has to be B522 or newer.
Tested by myself on B522, B526 & B528.
The steps required to get back pink/blue screen USB:
Automatic flashable zip is pretty much fail proof, but I have warned you.
Automatic method (recommended):
- Download update-B518-bootloader.zip from MediaFire.
- Save it to the root of your SD Card.
- Start the phone in recovery mode (recommended recovery is 5.5.0.4)
- Select "install zip from sdcard"
- Select "chooze zip from sdcard"
- Select the zip you downloaded before.
- Select yes.
- Reboot and enjoy!
Manual method (not recommended):
- Download the bootloader.bin (B518) from MediaFire.
- Copy it to the root of your SD card.
- Use a Terminal Emulator if on phone or start ADB and write in "adb shell".
- Write in "su" to get root rights.
- Write in "dd if=/sdcard/bootloader.bin of=/dev/block/mmcblk0p3" to copy the bootloader.bin from SD card to the bootloader partition.
- All done!
Protip: When using Linux distribution, pink screen mounts your internal SD card, data, cache and system partitions. This happens because Windows does not mount extX partitions by default.
I suggest everyone to do this as long as you have rooted your phone and want to flash custom ROMs/kernels.
Now you can recreate your backups with this tutorial.
Special thanks to dancer_69, who sent me B518 bootloader.5
Nope, but for the information, it's going to be an app named X5Toolbox, and from there you can flash recoveries, boot images, bootloaders, perhaps even AMSS, restore and backup IMEI etc.Wow!the big secret!

Some progress made, I have to work on the user interface. I'm not used to mobile app programming (especially the graphical part). First beta should be available within ~2 weeks.42.2 has pink screen already unlocked, so that has nothing to do with this. This is for flashing only if you have a locked bootloader, which is the B522 ROM.
I am creating an app to backup your phone fully even if it is turned on. That way there is a chance to restore the phone if something brakes during the process.
