P40 Pro unlocked bootloader - Huawei P40 Pro Questions & Answers

So let's say I have a method of unlocking the bootloader and I successfully unlocked it.
What would I be able to do since there's no official ROM or TWRP made for this model?

Congrats, Share your successful method to others first. Then someone will create the twrp or ROMs. Its my opinion/guess

post your method here on the forum and the developers will do the rest. Congratulation.

When the bootloader is unlocked it allows developers to make roms. So, by publishing a working method you will open the P40 world to roms and mods . (do it, do it, do it, do it !!!)

Unfortunately it's not a reliable method, it involves opening up the phone and shorting the test point but if you must know here it is:
requirements: a heat gun, a pry tool, a small + screwdriver and something like a metalic tweezer and a sigma box or other alternatives.
oh you're also gonna need some E7000 glue to put it back together
You open up the phone, remove the battery shield, remove the battery connector, short this point and plug in the usb right after.
After you just press unlock bootloader on your sigma key software
There MAY be better methods but this is all I can offer for now, it's really not worth spending $300 just for a bootloader alone unless you already have the tools.

I guess you can try getting treble info and install GSI roms on it...

It's not that expensive. 130 bucks for lifetime license. You can unlock it, brick it and fix it all at once.

You do not need to open it, just run it in download mode and perform the process of switching to Test Point mode - unlock fast boot. What steps do you need to take to - rip the software to modify? In order for developers to start working with software modification

HELP!!!! I need a alternate way to root My G1!!

I have been lurking in the shadows of this forum and it has helped me out alot so far. I finally registered after developing a bug or hardware problem (not sure which) with the original FW (rc33) that is preventing me from rooting my phone. Its with my QWERTY keyboard. It seems the entire top two rows are now activating more than one key stroke when i only press one, ie. press "e" and it comes up "3e". This really sucks when i get to the part of the rooting process to type "telenetd" before launching telenet. I have tried every combination i can think of to fix, but i am at a loss.
So, my question to all who can assist, is there an alternative way to root my phone other than the common way i find on all the forums? Anyway to do this thru the computer or anything? My computer uses windows vista. My phone has a non-rooted rc 29 (i did get that far in the process. i downgraded from rc33, got the recovery img on the root of my sdcard, along with the update.zip file. i also installed telenet from the apps store). I am ready for the next step is there is one for my situation.
I don't care how difficult or how many steps are involved, i just want to root my phone. Am i screwed or do i just wait for the official g1-1.5 and live with that version?
Red
P.S. please don't tell me to turn it in for servicing. I am currently located in the country of Bahrain and that isn't an option for me for about another year. yes i am in the military and kinda stuck. Thank you for any and all support you all have to give.
since you cannot send it in you should try servicing it yourself. i do not have the link to the service manual on hand but i know there is one out there. download that and get a few torx srewdriver heads(i'm sure there are a few laying around the base) take the phone apart and try it that way. or as i have done in the past firmly press your thumb over a few keys in those rows and run it back and forth a few times, occasionally it can help it the buttons are stuck beneath the casing in some way, or stuck together
if you can connect to a wireless network and get tenetd typed correctly you can get into your phone from the comp using the telnet command on the comp
have you tried the "app for that"?
http://code.google.com/p/androidroot/updates/list
I haven't tried it so I don't know what's involved exactly but it is worth a shot.
simply type out the commands as if your phone were working normally...then use the trackball and backspace key and go back and delete the unnecessary keystrokes
Here's how the keypad works, if you're going to open it up and try to troubleshoot it:
The keys are capacitive, so there's no direct electrical connection when you press one down. There's typically one set of contacts that run in rows, and one set in columns. When you press a key, it activates the sensor in that row and column, whereas the other keys on that row and column only see half the signal. That reduces the number of pins necessary to get inputs from all the keys.
So if you're pressing "e" and getting "e3", the column wire is probably working correctly but you're getting the number row and the top text row.
Try taking it apart and seeing if there's some dust or grit between the keypad and the circuit board. If that's not it, usually there's a ribbon cable that connects the keyboard circuit board with the rest of the phone. Both the socket and the cable itself for this type of connection are notoriously finicky.
Let us know how you make out. Also, why will it be a year until you can get it serviced? Are you in the pokey?
great advice!! and timely too!!!!
Hey guys!,
Thanks for the options, it didn't take long for replies and that shows how wonderful this community really is. I will keep you all informed as to my progress. unfortunately i am going to have to wait until the morning to attempt to find a set of torx head screw drivers. right now its 11:52pm and everything is shut down. No, i am not in the pokey, just unable to get back to the states until then and if you thought the mail service was bad in the states, you should really see this place. i am not going to risk my phone through that service.
ohnoezmahfone, thanks for that information. my gut feeling is it has something to do with that ribbon cable. about 60% of the top two rows of keys are doing the same thing. Now, i have never dropped the phone or jarred it in any way, so i don't know why it just started doing this. but then again, it could be dust too. That one thing this place has plenty of!!! Sand and Dirt!!!. as soon as i get my hands on those torx screwdrivers, i will report back.
Now, if someone has an alternate method that might work before i perform open heart surgery to this android unit, by all means speak up! I can build computers but have never dove into something this small, nor do i have all the tools i am used to having. But i will give it a shot. Whats the worst that can happen? I hose it up and spend 400 on a G2 later this year? . Not a total loss, i guess.
i will follow up soon,
thanks again all!!!

in case you dont have the service manual...

I used it to open one (got wet ) and it made the job very easy! One step at a time, and it really REALLY helps to have a plastic opening tool (or a plastic knife may work in a pinch).

gospeed.racer you are a lifesaver!!!! i recommend that .pdf to everyone. It bailed me out of having to enter the "g1, long distance throwing competition". Anyways, i followed the service manual step for step, took the g1 fully apart and when i got to the keypad module i didn't find any dust. kinda feeling like this was all for not, i proceeded to put the phone back together. once complete i powered it on. then i started to type and Holy Crap!!!!! it is fixed. all the keys are the way they should be and soon i will be on my way to rooting my g1!!!!!!
All of you here are outstanding and i am really proud to now be part of this forum. Thank you again, for pointing me in the right direction. I guess it must have been the ribbon cable not being seated correctly, causing my problem. well, not any more!!!!
Red
p.s. BTW i would like to thank all that posted in this thread. i couldn't have done this without you.
awesome that its fixed now. welcome to the world of root
get one of these http://www.androidaccess.com/sdcard/store.html
you wont need the top two rows of your keyboard to use it
it should reset your keyboard once you go back to rc 29 then it will allow you to just enter two commands that will root your phone. you can read about it here:

Question Who knows how to short the test points to enter the Qualcomm EDL flash mode

My Edge s bricked several days ago, Technical support said that there is no way to flah it back, except replace the motherboard, but the fees are high enought that you can buy a new one, so i give up, Today I disassembled the phone and tried to find the short test points to enter the EDL mode, But I don’t know which are the test points,Can anyone help look at the attached pictures, thank you.
Friendly reminder, Please don't try to relock phone like I did.
Unfortunately, I do not know what points to short in order for this to work, however I had a similar issue with my Asus Zenfone 6 and was able to resolve it using the following cable...

Just to be clear, did you try using the stock, factory firmware files and:
Code:
fastboot flash partition gpt.bin
fastboot flash motoboot bootloader.img
fastboot reboot-bootloader
I soft-bricked and did those three commands, then was able to flash back to stock via LMSA.
wow, I have the exact problem now for Edge S/G100 .... searching for "test point" brings me here.
I'll try the above FB commands and am still open for suggestions. Thanks...

I find that hard to believe; manufacturers love test points. They don't trash mobos over firmware... there's a way.
They aren't mark if present.
The location is likely proprietary until someone figures or leaks them out.
This is all I could find. Try asking here perhaps.

Nope, on more expensive devices, the boards between EVT, DVT, PVT revisions change a lot because they can afford to. Production boards for this phone simply don't have the pins for it.

Yes, well... the pin outs for that chipset are available from Qualcomm.
If there is no pin for that function on the chipset, then there's the definite answer that there's no way to do it. That's an easy way to verify it.
Otherwise it's game on...
The way to find it be to hot air the Qualcomm chipset off a trash mobo and trace out the correct pcb contact from the base of the BGA chipset (I assume it's a BGA form factor). The trace goes somewhere. While it could be s completely internal trace, I highly doubt that's the case. Even then there are still ways to get to it.
If the pin is there, there's a way...
Just depends how determined you are and you're skill level. Prototypes and repairs sometimes end up as scrap so you need to accept that reality as well. If you have a blown mobo to experiment and practice with you have nothing to lose.

about your advice do mean locking the bootloader after you unlocked it?
plz anyone plz answer me that my oneplus 9 5g has been hardbricked by me so can i fix it using edl cable??? plz answer as soon as possible.
Thank You.
To original poster: If you get Fastboot mode running which is what it looks like you were able to do, you can recover with the Motorola recovery tool. Otherwise if it shows up only as a serial device you need blankflash which I posted previously in this forum. I have bricked and unbricked my phone many times trying to get LineageOS and other things working on it since it's a little funky as a device swapping A/B stuff a lot on it's own.
Thanks

Was there ever a solution made on this issue? I have the same problem
FFS, people, If you can get into Fastboot, your device is not bricked. There was absolutely no need to open up the phone and disassemble it. You have to go into Fastboot mode to use the Motrola Rescue and Smart Assistant Tool.

Software or Hardware charging problems?

My Asus Zenfone 5z suddenly stopped fast charging i know its not the charger thats the problem, ive used it on several different phones and it still works. Now comes another problem, when i charge my phone and restart it while plugged in the charging symbol doesnt appear but i know its charging but slowly via ampere app. I need to unplug then plug it again then it shows the charging symbol. My PC's and Laptops cant detect the phone but charges it. I have the bootloadeer unlocked, but when i charge my phone powered off it pops up every few seconds and the LED indicator doesnt light up. I tampered with something then it fast charges all of a sudden, i even moved the phone around to ensure that the charger isnt faulty. Then when i went to go and charge my phone is slowly charges up again.
Any help? Do i just go to a technician? its harder because its lockdown where im from. Is it my charging pin thats faulty??
Maybe cleaning it can help, use isopropyl alcohol and a tooth brush or cotton swabs.

I echo what @XDHx86 has stated. At times, your charging port can be clogged up with dirt, lint, dust, etc... Cleaning it might resolve the issue. However, be sure not to use anything but isopropyl alcohol, preferably 70%+ solution.
Could be a charger port (PBC) failure if cleaning doesn't help.
Could also be a battery failure. Check for any signs of battery swelling.
Unlikely it's software.

no battery swelling, but i might go to a technician and see if they find a problem. As for now im trying everything before going. I did something, forgot what it was but it fast charged then i wiggled my charger around to see if it stops but it didn't. Tried plugging again and again but after a few hours it didn't fast charge again. Anyways what's a PBC failure?????
The charging port is mounted on a seperate printed circuit board in many phones.

You replace the port PCB. The port PCB can effect other seemingly unrelated systems when it fails depending on the manufacturer.
What warning? It may be a firmware or hardware issue. Normally the firmware doesn't go corrupt for no reason.
Possible mobo failure.
There's also the possibility of a rootkit infection.
If running on Android 8 this becomes more likely and if so it may need to be reflashed to purge it.
Is there any other kinds of unusual behavior when running?
You need a tech who is very familiar with this make.

I'm no expert on this, but is that a normal warning if you unlock the boot loader?
I'm not advising you to lock it as that may cause other issues but doesn't having unlock increase security risks?
In any event if it does have a rootkit* a factory reset should purge it. If it has custom rom, I have zero experience with them.
I don't like using factory reset as it's best to find the root cause instead. In your case it may not help at all if the root cause is hardware. You need to observe the symptoms and use the process of elimination.
This is one of the reasons I run a stock Android, in some respects it simplifies troubleshooting.
* be careful with all downloads especially side loaded apps. Playstore downloads aren't without risk though.
Email downloads are high risk; keep it all in the cloud whenever possible.
Check the download folder regularly for odd behavior and unauthorized downloads.

You're welcome. Sorry I couldn't help you more.
I be very careful about locking the boot loader.
Make sure you know the full implications before doing so.
You might consider flashing it to it's stock rom especially since the boot loader was unlocked when you got it.
Make sure it's functional enough to take a flash though, last thing you need now is to brick it.
If it's a hardware issue this should be corrected first.

I've tried factory resetting 2 times to no avail. It's a normal warning sign, its part of the booting process. But if i power off my device then charge it keep popping up every few seconds. Would a custom rom fix this? or do i just go to a technician now? Also for some reason only Type A to C chargers work. Ive tried my sibling's charger that's Type C to C and it doesn't work, but Type A to C works for them. Also my phone charges on my PC but it doesn't detect it despite having my phone on file transfer mode. I'm trying everything as it's hard to go to a technician especially during covid

Yeah, bricking it would be a bummer. I'm still researching on bootloaders and custom Roms in general. Tips on it would be great tho. And no need to be sorry. And I saw this reply late, I've replied to your previous comment.

The unlocked boot loader is suspicious.
Like I said if it's hardware is stable enough to do a reflash I would. Go with the OEM rom it originally came with for now so you have a known good rom loaded... it will simplify troubleshooting.
Error on the conservative side.
Letting a good experienced tech look it over is the safest route.
Finding one may be difficult. One that's does rooting may be more helpful.
On the PC try accessing it in drive management, try the rescan drives command.
The PC not detecting it maybe a driver issue.
In hardware management try updating or rolling back the driver. Try another port.
Reboot...
Look at Event Viewer for error messages after trying to connect the device.
If it's not the PC it maybe the phone's port PCB has failed.
Inspect the phone port carefully with a good light source and magnification. Look for signs of damage, corrosion or debris.
Try gently cleaning as mentioned with anhydrous (99%) isopropyl alcohol and a soft bristle toothbrush. Allow to dry in a low humidity room before using. Isopropyl alcohol is hygroscopic so it will grab moisture out of the air to some extant plus the cooling tend to do so all well.
A blower bulb or fan helps speed drying.

If it's not the PC it maybe the phone's port PCB has failed.
Inspect the phone port carefully with a good light source and magnification. Look for signs of damage, corrosion or debris.
Try gently cleaning as mentioned with anhydrous (99%) isopropyl alcohol and a soft bristle toothbrush. Allow to dry in a low humidity room before using. Isopropyl alcohol is hygroscopic so it will grab moisture out of the air to some extant plus the cooling tend to do so all well.
A blower bulb or fan helps speed drying.

If don't have the skillset it be probably the best plan. Ask about experience and pricing upfront.
If you can see the techs working and using ESD mats/wrist straps that's a good sign.

it looks like this when i restart it by the way. Mind you the Charger is secured. And at the end i unplugged then plugged it again then it charges. I've tried using the phone while charging to see if it stops charging but it doesn't, so i ruled the charger out of the problem. Thanks again.

You shouldn't need power it off to recharge.
So it won't charge unless powered off?

Factory reset a Phone with broken screen

Hey guys.
I have a Samsung Galaxy a51 but last week the screen broke. I cant see anything besides green lines and such.
Now i wanna either repair the screen or throw it away. But i wanna do factory reset in all cases. I think there might be possibility in recovery Mode but on this phone seems difficult.
So anyone with a Galaxy a51 can you probably tell me what and how i have to press to get blindly to recovery in order to execute the factory reset?
As another notice: i never used any unlock code, but since digitizer is broken also i cant use touch. Vol+/- and Power is working, device is powering up but not adb . It shows as symbol on pc but since i cant swype to top to get off Lockscreen i cant access the folders.
Maybe someone can help
If you're going to throw it away simply use the 5 pound sledge clean wipe technique.
Otherwise you'll need to bring up the boot menu and count down the menu mentally as you click the volume key... you get the idea.
The 5# sledge is a lot easier
Okay so destroying the device is easier? I thought so. But maybe i can even do better and fix the screen myself, this would be another way.
Another idea would use otg with HDMI and usb but not sure if it would work
I'm just saying if you're not going to try and repair it... not saying it's the wisest course of action.
If you change your Google and Samsung passwords most of the links will be locked out anyway.
This is another overlooked advantage to having an SD card and using it as a data drive.
You can simple physically remove the data.
Humm. I think it will depend on how much i wanna spend on it. I dunno how much is it worth? I think it was around 280€ (Well yes euro, im from Germany anyway).
I got my phone (a samsung galaxy note 5 (sm n920c)) bricked while flashing stock firmware with odin. The process ran successfully but the phone couldn't boot further after showing the Samsung logo. I can't go into developer options and enable usb debugging or enable oem, unlock bootloader and boot a custom rom etc since the phone won't work and everything is locked.
I tried to flash twrp with odin but no success. On top of all these things now the phone won't stay for longer in the download mode (odin mode) except for few seconds, may be I have lost support for the battery, and I can't get to try a different method such as custom cwm recovery for getting into the recovery mode and installing a custom rom. I have tried to remove the battery and rely on external power but I don't know why the phone doesn't even go into the odin mode without battery.
Is there a possible solution or I should feed my dustbin something valuable.

Add to that thought there may be more damage than just the display. Tough call especially if money is tight.
@blackhawk we're still not done. Add costs for the necessary tools. And think about the working time humm. Doesnt fit the bill. Suddenly the 5 pound sounds pretty good. Maybe i Just lay it under the wheel of my car, just drive over it. Might work as well lol

Microwave oven, bonfire... ideally you want to destroy the flash memory chipset but that's probably way over kill.
I wonder if i break the phone if the battery could potentially explode. This is why i would simply deassemble the device and kill the board

Just drain the battery before hand. Or set it aside for now, no rush.
Yes there is really no rush. Luckily i have a second phone which with im writing currently. This is working very fine.
I always use a case. They've saved my devices countless times.
This time i used one with only back protection. I should have known better. But the flip books are Always getting dirty. Feels dirty after few months but well this one here now at least have a flip book cover
This one. Easy to hold, clean and doesn't attract dirt. Pretty good heat dissipation.
Excellent drop protection. Never comes apart in a drop. The case kick stand eventually breaks but it's not needed.
My N10+ has taken close to a dozen 2-4 foot drops onto concrete with zero damage. It wuvs to corner hit when it's not face planting.
Nice. Thanks for the recommodation i might as well try this one.
Btw, i did what i mentioned First.
For all ppl that wanna factory reset their phone blindfolded, whyever:
1. Let the battery die
2. Charge it for ca 5 min
3. Connect to pc, hold power and vol up until it vibrates. Let go of power button as soon as it vibrates.
4. Press vol down exact one time and then press power button
5. Start fastboot on pc, Check if device is connected
6. Execute fastboot -w for purgeing userdata
7. Reboot with fastboot reboot
Now the 5 pound can work as well
But one thing is certainley strange. After i played around with fastboot oem unlock without activating unlock oem in debug menu it shows on every pc as unknown device and never boots up. Feels like its bricked. Very strange thou. Probably the battery died while try to execute fastboot unlock or sth
And yeah its starting to turn into a hobby of mine to play with devices til they get Hardware bricked. The Huawei p20 suffered a bit different but also somehow relateable damage (tried to unlock bl but short circuited everything on the PCB lol). I cant deny its fun to Check out the edge of possibilities there are in android phones

How to recover data from broken phone with PC?

I have a Huawei P20 with a broken screen, the touch does not work and I have a password and therefore I cannot unlock it, I would like to be able to get all the data back from the phone and I have tried in many ways how to do it without being able to use it and the only solution is do it through a computer, I have already tried to activate usb debugging with a program, only it shows me the notification but I can not approve, I checked if there was active ADB but it says it is unauthorized and now I wonder if I should send the phone in recovery mode or fastboot mode so that I can control it from a pc or somehow receive the data, the question is how can I do? I have no idea how fastboot or recovery mode can be and whether it will make me lose everything or not so I would like to make sure by asking an expert, I would be very grateful if you could help me.
Easiest way is to replace the damaged parts or temporarily jumper them in. No guarantees though; any impact that can break the display could have damaged the mobo.
Always redundantly backup critical data... for times like these.

But I know there is a way to get the data back without need to replace or repair, in my case is the screen broken but the phone works well but I can not do anything

That may be the only way especially if the touch screen doesn't work. A repair shop may be able to help if they have a parts queen of that model laying around.

Maybe so... best not to put yourself in that position to begin with, because eventually you'll likely lose data.
