At a previous time I tried to root my Huawei and didn't get very far. Mostly all I got accomplished was to unlock the bootloader. I gave up on it at the time and returned the phone (I thought) to its original condition. I did not then know about tamper fuses and such. Consequently, my phone now will not accept any OTA updates. Oh, it goes through the process of downloading, but it won't install. Instead it gives me a screen that starts with: Your device has failed verification and may not work properly.
Is there any way to get around this? Possibly reloading the entire stock system? Tell me what I can do if anything?
Can I at least tell Huawei to stop sending the updates somehow. If they are not going to work they are just annoying.

Hi,
So I wanted to prepare my unlocked Nexus 6 on T-mobile for my brother by completely un-rooting and then relocking to setup stock firmware. With the help of “Nexus Root Toolkit” it was a quick update. I simply picked up the latest firmware for t-mobile, then relocked - and off you go.
The Phone was ok for couple of days, but then google pushed new update – which would render my phone useless. After update Initially the phone went through the boot almost to the end, and then exception happened. Something about system UI crashing and then screen was unavailable. So I could not do anything on the phone.
I tried fixing with “Nexus Root Toolkit” (unlocking, rooting etc.), but at this point the phone is stock on booting (few colored dots signifying loading), but the phone never actually boots. Going to Factory reset or Recovery does nothing.
Is there anything else I can try please?
Thanks,
-Mariusz

There's not much you can do here. If you don't have TWRP or unlocked bootloader, you should just RMA the device direct through Motorola.
You could try to sideload the update you had received that caused this.
Other than that, RMA.
I was hoping not to hear RMA - but thanks for the reply.
Greetings everyone!
Few weeks ago, I gave my device to a friend of mine to manually update it. Something went wrong so he decided not to go any further. Yday i tried to "Factory reset", after reset some error pop'd in the left upper corner of the phone.It says:
[LGE_SECURITY] ERROR: boot image signature
Critical failure: Unable to start kernel.
Unrecoverable bootloader error (0x00000002).
Anyone had any similiar or even the same problem as i am facing right now? Thanks in advance.
best regards, Milan
Guy didn't know what he was doing apparently. Your handset is still locked and he apparently tried installing a 3rd party ROM, lemme guess, you wanted a newer version of Android than 4.1., which is a reasonable enough thing. Problem is that out of the box you can't do that because it only boots images signed by LG and they abandoned development after releasing 4.1 and a couple of minor point releases. You aren't totally screwed but if you were having somebody else do it for you, you might need to get some help. You can find the details elsewhere here, or more likely point a more skilled friend at it, but here it is in a nutshell.
You need to get LG's official updating software (from the LG website) and you need to fiddle with it a bit until you get it to do a rescue because it expects to have already paired up with the phone while it was still working. If you already had it installed, great because it will make it easier. Anyway, you will probably have to manually pick your model and input the IMEI since it won't already know those things and it will go out and fetch the most recent image. You will push VOL Down and insert the USB cable from a powered down state, it will then do the rest. Good chance you will even retain your data unless that 'factory reset' you mention actually succeeded.
Of course that will only get you back to stock 4.1. Read around for the official way and several un-official ways to unlock your boot loader. Once that is done you can install a better recovery and then a newer version of Android. But the first step is to restore the stock software since you have to have a running phone to be able to unlock it.
And no, nobody has ever been able to explain WHY they lock them, but every single manufacturer seems determined to do it, chipmakers put a lot of work and ad copy into how extensive and unbreakable the locks on their newest chip is, etc. And then they either bow to customer demand and add an unlock feature or we here at xda do it for them... as a courtesy of course. Truly we do live in the asylum. Wonko the Sane was onto something.
I'm running a P7 with the firmware it shipped with and I'd really like to get it up to date, but every package I've tried so far has failed during package verification. There seems to be very little info on how to update your phone from such an old build. Can anyone please help because I'm at my wit's end here. I have a limited date cap so can't just keep downloading updates in the hopes that one of them will work.
I would be greatly indebted to anyone who could help me. This issue is making me want to cry.
Do you have a phone with a provider/network lock? Which roms did you try so far? You may give B133 a shot, if that doesn't work you'd have to go the way over a custom rom and then getting back to the stock one. I can describe the process more detailed in case it's necessary.
Thanks for the response!
I think the issue is that it is a network locked ROM. I got the phone from a provider called Vodacom and get their splash screen and everything. I went to speak to them and they told me I'm not supposed to be able to update my firmware because that requires rooting the phone, which voids my warranty. Sales people being sales people, I'm not sure how truthful this is. I can't imagine a provider refusing to let you update your phone.
So far I've tried B133, B609, B617 and B853, none of which works, sadly. Someone suggested I unlock the bootloader and I got the unlock code through the Huawei site, but when I try to boot using the three-button method it tells me that no update.app file was found, so I'm not sure how to get to where I enter the unlock code.
Hm, you might search around a bit and find an easier way, but if not, unlock the bootloader, flash twrp and any emui 2.3 based custom rom. Then flash the stock recovery and make a forced update (3 buttons) with B133.
To access the bootloader you have to press volume- and power until a white screen with some text appears.
Anyway, to update would definitely be worth it.
Yeah, I did precisely that last night and ended up soft-bricking my phone. It wouldn't even work when I flashed the original firmware. It's currently in at a repair shop and I hope they can fix it. Lesson learned though.
Thanks for the help anyway.
It's not that easy to hardbrick the P7, it's very likely that he will be able to fix it! With some time for trying, you probably would have been able to do it by yourself, too.
Your very welcome
Yeah, the thing is I was up all night trying to fix it. Flashing it back the original software should theoretically have done it, so I have no idea why it didn't.
I have encountered device corrupt error on my pixel 4Xl few days back.. In few instances device worked normally for few hours but kept on switching off and getting the same error as device corrupt. I did factory reset once when I could switch on the device as suggested but currently issue is still persistent. I am using original OS Android 12 with latest Nov security update installed. I have never sideloaded any apps or done any changes to my OS. Device is always upto date with updates available. Please help me with any resolution to fix this issue. Currently my phone is out of warranty by few months.

Sounds like your bootloader is locked? If you have done a factory reset and the issue is still there it is more than likely a hardware issue you cannot fix. You could try flashing a full OTA image from recovery mode using adb on your computer. If this sounds like too much, I would still call Google. I have had my phone replaced twice, once outside the warranty. Just explain everything you have done so far (they may ask you to factory reset again to verify) but you may end up being covered out of warranty. It is definitely worth a try.
Hello,
did you do an OTA update before your problem ? If yes, it's not the right one that you used, in this case, you just have to update again with the right version.
Hey!
Did you try this tool form google: https://flash.android.com/welcome?continue=/?hl=pt-br
It allows you to flash firmware, even if the bootloader is locked. If the botloader is unlocked it allows to make a full firmware flash, if not it flashes only some partitions.
If it doesn't help, and you have the bootloader locked, you will need to use the EDL mode.
More on that on this thread!
Good day all. Long time lurker of these forums, and I am officially throwing in the towel on my amateur attempts to update my P20 Pro (CLT-L29 C636) from Android 8 to something newer. I've managed to soft brick the thing, getting stuck in a boot loop. I can get to fastboot, and I can (sometimes) get it to enter dload mode with an OTG cable and a thumb drive. I messed something up early on in the process and I am completely unable to go any further. Dload gets to 5% then fails every time, with every thumb drive I've used.
I am willing to accept that I just don't have the technical ability to take this journey any further. Being that I live in the US (Western New York), Huawei lists no official repair centers in the states. Are there any trusted 3rd party repair services I could send my phone to and have an expert attempt to repair the software? At this point it's been bootlooping so long the Huawei logo is ghosted onto the AMOLED screen. I would love to have this phone operational again.
Any thoughts I would greatly appreciate it!
Hold Both Vol + Power until Emergency Rescue pops up.
After that, restore Stock, unlock Bootloader, install any android 10/11/12 GSI u want.
Tried that. It's stuck in bootloop and only occasionally responds to boot prompts. On the couple of times it got past dload failed and prompted me with invalid install and offered to boot to Emergency Recovery, it fails to load the recovery dialog and drops back into a boot loop.
I promise, I have been back and forth with attempts on this phone for four months, and if I thought there was any new surface level tip or trick I haven't tried, I would still be searching. I feel like it's at a point where only specialized software or a physical test point, or something else beyond my technical ability will fix this phone.
I do appreciate the suggestion, though.
Unlocked Phone? So it *might* be possible to recover i imagine if u get twrp running, might need some dirty work, but not impossible.
Edith did forget to mention; Can u see ur Phone via adb/fastboot on your PC?

Sorry if I sent the wrong impression. The bootloader is still locked. It is only carrier unlocked.
I can locate it on DC-Unlocker on fastboot but it won't let me load any files to it.
With locked BL is not much hope left i guess. Hisuite Recovery fails too i imagine?

Oh yeah. HiSuite recovery states that this model isn't compatible with eRecovery and to take the phone to a service center.
