A couple questions about softmodding the phone - Huawei P20 Pro Questions & Answers

Thinking about getting this phone, the only thing holding me back is the fear of not being able to completely return to stock in case I need it for warranty. Is completely relocking the bootloader possible? (So it doesn't show something different like "relocked", like on Sony.)
How easy it is to brick the phone?
How is "rebranding" to dual SIM possible? Wouldn't that require hardware changes?

Would like to know this as well please. If I root and return to stock, does the phone show the annoying screen like Samsung which shows phone was previously rooted?

How to Purposely BRICK dream!???

I was wondering if anyone knows how i can purposely brick my g1/dream. My keyboard is fcked up and I know that i still have T-Mobile's warranty. I just wanna be able to brick it where the T-Mobiles center's employee cant boot into recovery and get passed the G1 boot screen...any advice?
(Should i revert back to stock recovery img and rom? Then flash danger spl?)

Downgrade the radio w/danger spl installed
Or if not install danger spl without the newest radio
the same way many of people have "accidentally" bricked their phones. just do what Diceman4 said, good ole 1.33.2005 can do it every time.
Curious why you would want to brick your phone, t-mobile will replace it just because the keyboard is bad, they replaced one of mine because the sd card reader stopped working. I'm not sure if they have measures in place to determine if you "bricked" your phone of if it was a faulty phone, but if you can revert to stock firmware and get a warranty replacement, why go about that way?
so if i use any of these methods...the employee wont be able to boot into recovery? or should i revert back into the original recov...just incase?
(i dont exactly want him to see RA's version)
The keyboard doesn't work, they should replace it under warranty.
Keep in mind there's a fee involved if they determine the phone was damaged by you and it was not a defective unit, I'd play it safe and revert to stock firmware and then warranty it, but that's just me
well it's not completely dead...it's just that the space key doesnt press easily. you gotta force press it for it to work. i dont wanna hear some **** that it's not under warranty cause i damaged it for whatever reason.
As long as your phone doesn't have any cracked plastics and your ldi is still white you should be fine. Just unroot and file under warranty. And just to speed up the process tell them you've already master reset the phone and you're still having the same issue.
I'm having the same issue with my space bar as well. For the second time. Faulty design? I always keep my hands clean and have never spilled anything on the phones. I don't even take them out if it's raining outside.
You have the white version? Both of mine have been white. Have a friend with a black G1/Dream and his is fine. Let me know how your return goes.
My ADP1 does this...i just live with it.
Geeze... warranty?
This is something that can be cured by CLEANING it.
Open it up, take the keyboard apart, clean it, put it back together. Fixed.
the keyboard connectors are a sealed thing, ive already had is stripped with mine as i have a dodgy backspace and enter key,

Is it possible to change the bootloader image?

Has anyone managed to change the bootloader image that shows up before the boot animation? I'm talking about the still 'X' image that first appears when you start the phone.
What I would REALLY like is a way to remove the unlocked icon below it. I'm not looking for a way to hide that my phone is unlocked, I just don't like being reminded of the fact every time I start up my phone. I prefer everything to have a completely OEM look and feel to it. Hopefully that doesn't sound crazy...
No, I believe the nexus has a locked SPL. At least if there was a way to change it, I think we would have seen that by now.
there probably is a way to change it, we just don't know it. people have sent their unlocked phones off to htc, and had them returned locked. so...there is a way to do it, we just don't have the tools, or a workaround.
yet
Well I look forward to the day someone figures it out. It's a shame Google/HTC went to such lengths to void warranties.
they didn't void your warranty. you did, lol.

Brick definition

Is it a state when there is nothing you can do (software-ly) to power-up your N1 no matter what?
So, if that's happened, what is solution for that?

Thats really vague. There is a method somewhere where you take the battery out and plug it in to the wall charger then instert battery to turn it on, which would be a troubleshooting method of whether your Power button is broken.
Definition of a brick is:
No fastboot
No recovery
No other screen than the original first Nexus One splash screen.
If your device will not power on at all:
What did you do to make this happen
Sounds like a hardware issue if it will not power on at all, ie, you can't see ANYTHING ON THE DISPLAY WHEN ATTEMPTING TO POWER IT ON.
A bricked phone is in a state where you can't do ANYTHING, from software or hardware, to recover the phone. It will just be stuck on the X logo which appears on bootup. There is no solution for it, hence the word "brick".
In general, N-1 is very resistant to bricking - it only happens if you pull out the battery when flashing the radio or something..
Thanks for sharing. So, is it any ways to unbrick the N1? Do we just throw it to the trash can?
By the very definition, "brick" is something that we can't recover from. If it were recoverable, it's not a brick
Okay, i got that. But i'm wondering, what if brick happened to you. Will you throw the device to trash can? Or send it to repair center maybe so they will fix it. My question is, if they can fix it, how?
HTC can fix the device, but it won't be under the warranty. I am guessing they have hardware to actually flash the radio (and other), and don't need to depend on fastboot like we do.
Thanks for sharing your thoughts.
To be crass, it basically means that you're ****ed.
Nearly any issue can be fixed as long as you can load fastboot or ADB. From there you can reflash the recovery image, format the phone, and start over. If you can't load ADB or Fastboot and it won't boot normally, it's effectively "a brick", only useful in it's physical ability to take up space. A paperweight.

Send it back to HTC and they will replace the SOC, for a price.
OP, I doubt its bricked. Its very difficult to brick the N1, like another poster said you'd have to interrupt the radio flashing process.
Explain to us what happened
Explain to us what happens when you power it on.
You only have 32 posts, I am quite certain there are other options than throwing it in the trash.

[Q] Relock Bootloader on P880

So I did some research on the xda forums about relocking the bootloader on the p880 and it seems like it is impossible.
My problem is, that under my screen there is an growing amount of dust, which really bothers me especially when I'm outside and the sun is shining on the display.
I would still have about 1 year of warrantiy left if i hadn't unlocked my bootloader, since it is impossible to relock again myquestion is if there is any way to change the text, that is displayed in S/W upgrade mode from "Bootloader: unlocked" to "bootloader: locked" so it would at least appear to be locked, when I send it in for repairs.
Thank you in advance!

They can't tell you unlocking bootloader makes dust under the screen but it depends on the terms of your warranty. In some regions warranty still works after unlocking since they can't prove that you done any demage to the device. First read your terms maybe you are lucky :good:
Thanks, but unfortunatly the terms say, that bootloader unlocking voids the warranty, I'm from Germany by the way...
"is there any way to change the text, that is displayed in S/W upgrade mode from "Bootloader: unlocked" to "bootloader: locked" so it would at least appear to be locked, when I send it in for repairs."
does anybody have a solution for this?
You can try to flash the stock 4.0 rom (v10).

After this, try to update to v20 and see if it's work. Check if "bootloader: locked" on v10 also .

If you're from Germany, the unlocked bootloader shouldn't be a problem. I believe that European laws state that the warranty of electronics can't be voided by a change of software as long as that change didn't lead to the defect. In the case of dust under your screen, they probably won't even check your bootloader.

There's already a thread about your issue here
I believe that flashing an ICS firmware should at least "camouflage" your unlocked bootloader
Just in case, anybody ever needs this information: there is indeed a paragrahp in the european laws, that states that the seller always has to give you 2 years of warranty, even if you change the software, as long as you can prove that the error didnt result from that action.
I bought my phone from amazon.de so I will contact them in the next couple of days and I will report back here to tell you about the results!
Thanks for the help!
So my phone returned today. They fixed it without any problems, BUT they somehow relocked the bootloader, now it is impossible for me to open it again, as I always get a small red Text in the upper left hand corner that reads "LG SECURITY unlock permission denied"
I've been searching for a solution all day, but I found nothing :b

lg support has a habit of doing that. it may be permanently locked
It wasn't sent to LG it was sent to Amazon, and from there to W-Support, a german repair center thing.
I wonder how they managed to permanently lock it...also they messed up my display (there is some kind of white stuff under there :b)
an a part auf the plastic that surrounds the handy is broken, so I will send in in again and if I'm lucky i will get my Money back, because they hat the oppurtunity to fix the error 2 Times and they screwed up both times, so I now have the option to get my money back :b
I do believe that the Tegra 3 SOC has PROM guarded by a series of fuses. Contrary to EPROM and EEPROM, PROM can be changed only once. So, by unlocking the bootloader, there is no way to change it back. Unlocked bootloader stays like that forever. They can only replace the whole SOC to reverse the situation, but thats like putting another screen in an old TV - it's not the same on that came with the phone - the old one is still unlocked.
Thats what I wrote them, because I didn't want anything but the screen replaced and they didn't notify me in any way that my bootloader will be permanently locked, because if it really is permanently locked the handy is worthless for me. I would rather shoot myself than sticking with the stock Firmware
No, it cannot be relocked. Physically impossible.
It can only be "relocked" by replacing the whole Tegra 3 SOC inside the phone and I'm pretty sure they don't do that anywhere. Besides, if they were to do that, it means you get another brand new, unlockable bootloader to unlock using the same procedure as the last time

But i tried every possible way to unlock the bootloader again, and the tool from here http://forum.xda-developers.com/showthread.php?t=2263627
gave me the error: all fuses blown, bootloader permanently locked
all the other ways of unlocking just gave me the error "LG SECURITY unlock permission denied" no matter whoch one I used. I even tried EU-Open Firmware, and the german one
Did you actually try to flash a ROM or did you just probe the bootloader for unlocking?
Second, try the official way of unlocking.
I used every way of unlocking that I could find, after each try i checked the bootloader state in hidden menu and every time it read: LOCK
the I redid every way with the EU-OPEN .kdz but still no results
btw. the official way was the first one that I tried
So, you didn't try to flash any ROM other than official LGs'?
@UsernameWasTaken: It's true that you can't change burned bits in fuses. That's why our device is designed to use more bits for bootloader unlock checking and if all fuses are burnt, it means a locked state. So basically it can't be unlocked again as far as we know at the moment.

@Adam77Root, yes, I've been reading upon this, but didn't realize that blowing all fuses locks the bl. I thought it meant blowing them with incorrect bits. This description is a little too technical and convoluted for an average reader, plus the writing style and language don't help one bit to easily understand what's going on.
So, presumably, one's phone's bootloader can and probably will be permanently locked by the repairmen, no matter if the owner messes with unlocking or not? They blow the fuses as standard procedure during repair, correct? Yet another d*ck move by nVidia.
As I understand it, there is a total of 16 fuses and all can be blown one at a time using this future81's method. Each separate fuse's current state defines whether the BL is locked/unlocked, or is it a combination of them?
All in all, I would guess that following the official unlocking method is a poorer choice than using future81's Unlock.apk, as long as there is no need to RMA the phone.
OP, I'm sorry they messed up your phone. If you can, replace or return it.
Main point is that you have 16 chances to change lock state, but once all fuses are blown, it remains in a locked state that can't be altered.
I don't think they blow the fuses always, but only if the BL has been unlocked. Maybe they want to punish users for being curious and messing with lock state.

Is there a way to safely restore warranty after bootloader unlocking?

Hi!
I am an owner of moto g5s plus and while I enjoy the phone I think there are a lot of things the phone could be improved by software-wise, and while I'd love to unlock it's bootloader I am not quite sure if it's possible to restore it's warranty after unlocking it. I read a lot of different opinions. Some say that after restoring the phone the ADB says our phone doesn't have voided warranty, but some say that the phone has a fuse which breaks after unlocking the phone and some even say that I lose my warranty as soon as I redeem the unlocking code for my phone (which I already did so I guess I am in a pretty bad spot already ).
Thank you for your answers!
Correct that the phone has a fuse sort of thing like samsung. Once you unlock the bootloader you trigger a unlocked message and also internally trigger that fuse thing. Once unlocked via the code moto sends you, you can unlock and lock at will, but internally moto will know if it's been unlocked or not, and then has the option to deny warranty repair of any kind. Will they? not always, can they? by all means they can, and have at times. I haven't had to send in any phones from them, but I have had at least 3 variants of moto phones over time, and have unocked each and every one. I have also re-locked the bootloader which then takes off the bootloader nag warning, but as i said internally moto will still be able to tell.
I have also flashed bootup screens successfully so as you would never know it was rooted without know what to look for.
So in short
-yes you can unlock it, but it triggers a stamp/fuse that moto will know.
-You can lock and un-lock at will after you unlock the bootloader via the motorola site and code.
In my case I gave my daughter my moto phone and she does not need root so I formatted, re-set the phone up to factory, and then re-locked the bootloader, and no one was even the wiser. It was like a factory phone. The only ones who would know are motorola themselves, aside from that I have had phones in for repair at the phone places and they didn't even suspect the phone was rooted.

When you unlock, you have to register with moto and get an unlock code. They know, all they have to do is check a database. You lose warranty, how strictly moto enforces that is unknown - although I have seen an example where a fee was charged for replacing a piece of defective hardware after relocking and restoring stock firmware.

Yep, that is correct.
I've had people I know that rooted and sent it in and moto didn't say a thing about it.
I kinda think some of these companies are getting more lenient on root with the phones. People like samsung and apple are pretty hard core but I think some of the others are not as harsh as to what they are doing these days. I know that I've brought my phone in, and even told them over the phone it was rooted and they didn't even blink an eye and still offered support for stuff, in fact I asked a tech if he could possibly reset the phone via his machine (I forget what phone it was) but he had no problems doing it, and didn't ask any questions either. This was a phone that I remember I couldn't just re-flash stock firmware or anything. It's been awhile back, but it just seems like companies are getting less and less aggressive on root, at least to me anyways.
It is however ultimately up to the company to cover the phone or to refuse coverage, and charge a fee, it's a 50/50 toss up, so if you do decide to do it, realise the end result, that said company "can" refuse service. If your ok with that, there aren't any adverse affects to rooting as far as the phone functionality goes, everything functions just the same as when it was not rooted, but the benefits are you have choices to use things and apps that only work when rooted ie: titanium backup is one that comes to mind.
