[Q] G510 - Image signature verify fail - Android Q&A, Help & Troubleshooting

Regards to all!
Another brick I know...
I tried to install TeamWin, found this post on htcmania com showthread.php?t=591253.
Anyway on step 4. Ejecuta windows.bat the install-script I mess up recovery.img I suppose.
When I Power ON phone, I got this message:
Image signature verify fail!
Your boot/recovery image may have an incorrect signature.
...
Only have access to famous "Pink screen", tried many of update.app but every time it fails.
Also, is it necessary to unlock bootloader for this update.app, or to do something else, because it keeps fail on every firmware for G510 and Y300 that I try by now? I'm newbie to this, so sorry if is this stupid question (which I guess it is).
Is there any solution for this, any suggestions guys? Please, I'm close to breakdown.

Almost sure that I'm doing something wrong, tried these ROMs below (maybe some other also, but I wrote these in note later) and same error "Fail" .
B165
B166
B173
B178
B189
Anyone with idea?

---

I manage somehow (friend bought at same time) to find out potential ROM version, B195.
Googled for it, but no success by now.
To be specific: V100R001C00B195
Does someone have a link maybe?

Have a friend who works in phone service. They have an original ROM and he Flash it.
So for the future people who have same problem, here is explanation which I found on net:
"FAIL VERIFY IMAGE SIGNATURE":
The explanation is that the original recovery has a function to install zips with a particular firm, in this case should be Huawei.
However, almost all the ROMS officers who have taken both individual operators and Huawei for this phone have been format Update.app, installable using the "Firmware installer" phone and all had considerable weight.
But there have been some cases in which any operator like Orange Spain, used a zip supplied via OTA (like Update.app ) weighing approximately 90 MB (A minor update) whose function is to update the compilation B179 to B195, and what happens with this update zip format, is that the system makes a brief signature verification bootloader and the recovery and boot.img.
If the system detects that the Bootloader, the recovery or boot.img not have the original signature of Huawei or have been inserted through a hack or the like without having unlocked the bootloader officially, we will automatically display the following message after trying to install "Image Verify signature fail" in red letters.
The reason is surely and as I said before, we have unlocked the bootloader by an unofficial method or change some of those partitions by some hack before installing the zip, and this zip file contains the bootloader, recovery and boot.img because of their small weight, ie, is not able to replace him as the Update.app to return to the originals and leave us avoid this error signature verification.
A Update.app Bootloader completely regenerates us, so they used to solve 90% of problems. In this case we have no salvation unless there is a compilation format've tried installing Update.app or higher, and all other Update.app will Fail in the installation.
In the case of Orange model no Update.app the B195 is no compilation or compilation superior format Update.app , so we must take the SAT to have it fixed, and of course, do as we do not know what happened if we submit to third grade.
Solution is to find adequate ROM and flash with it. Mine was as I mention V100R001C00B195 and on net I can't find that one, so phone service was my destiny. Hope someone else will have more luck.
Regards!

You need to put the UPDATE.APP in a folder named "dload" in the sdcard and push vol - and + at the same time then power until it shows updating

Um, just take out the sd card, put it in your PC with an adapter or something and copy the files there?

Hi,
as above, the same problem with my sons G510. He has a Huawei G510-0100 phone, with a 4.1.1 Android, Vodafone (European)version.
I'd try to flash TWRP to install a custom ROM, but the phone now shows only that the image/recovery signature is invalid. The phone doesn't starts, can't enter in fastboot or recovery mode, but I can acces the pink screen. Thats all, the phone is stucked there.
How can I repare this halfbricked device?
(PS.
From Huawei's webpage I downloaded the factory G510-0200 Kernel (3.4.0 version, .rar file).
My phone is G510-0100 version.)

---

Solved.
I had the same problem. I installed custom recovery and I woke up with error "Your boot/recovery image may have an incorect signature" bla, bla, bla.
How solved I? Simple.
You must reflash stock rom for your Huawei Ascend G510 (0100, 0200 or 0251). If not know your version? Don't wory. Download and flash everyone version until result is ok.
