Which test points to short to flash locked device? - Xiaomi Mi A2 / 6X Questions & Answers

On the board I see six test points. The question is if any of these can be shorted to be able to get the device in a mode where it can be flashed despite being OEM locked.

OK, so the test points are below the fingerprint flex cable connector:

Here’s roughly how I proceeded:
Made sure that I’m grounded by touching a grounded metal piece in my apartment.
Removed the SIM tray.
Opened the device according to the instructions by Wit Rigs (youtu.be/1VIdpuXSFmI). Separating the top with the screen was quite hard as it is glued.
Popped out the battery flex cable connector, then the fingerprint flex cable connector.
On my laptop (Windows 7 X64) started MiFlash 2016.08.30.0, downloaded from en.miui.com/thread-345974-1-1.html.
Inserted the USB-C cable that came with the phone into the phone. (not yet into the laptop!)
Using a bent and cut staple, I connected the test points, then inserted the USB-C cable into my laptop.
Windows reported that a new device is connected.
Removed the staple, clicked refresh in MiFlash: A device showed up.
Flashed the latest official stock Android One ROM V9.6.10.0, downloaded from en.miui.com/download-353.html:
Initially I got a message that MiFlash cannot receive a “Hello” packet. It turned out that I was too slow. After connecting the device, one only has limited the time to start the flashing. I read elsewhere that it’s 15 seconds.
Success, my A2 boots up again! Now I’m only waiting for thermal paste to arrive in the mail, I will apply that, then close the phone again.

Can you upload the photo else where and provide a link maybe?

Please stop opening new threads for the same issue.
I think this is the third one I have seen now. I'm sure someone will be able to help you but with the phone being as new as it is you may have to wait or figure it out for yourself. I have the phone but have not tried root yet because it's too early in the phones life to be messing around with it. Let the community grow first.
I do hope you made to get it solved though and if so you could document it so we can all learn from it in the future

Coming from Q&A platforms such as StackOverflow, I was assuming it’s better to use separate threads: The other ones are about Magisk on the A2, about clean installing the A2 ROM, and about using a deep flash cable on the A2. Finally being able to upload pictures, I am now fleshing out my earlier posts with details.
Anyhow, I hope that the information can be of help for others!

I bought a Mi A2 and tried to put android pie on it, but I failed successfully. I'm gonna try this endpoint method, cause I cant flash images with fastboot.
Unfortunately I can only try this on Monday, cause I don't have the tools, but a friend in college has. I wanna know a few stuff for the grand day:
You told that the device is glued. Is it really hard to open it? and do i need to glue it back?
In the endpoint method, I need to manage to connect the two points with a metal tool, right? And i'll do the process with the battery disconnected, correct?
You wouldn't believe it, but this is my first android and I had it working for less than an hour. I have always being an apple user, but my devices were always jailbroken. I thought that with android things would go easy, but I ****ed them up hahah
As I saw you posted somewhere else, I always like to push my devices to the limit and thats why I am a computer science student...
thanks a lot anyway, and wish me luck on Monday!! Hope I can do it...

I used an X-ACTO knives (careful!), and yes it was somewhat hard to open.
and do i need to glue it back?

The A2 is glued with double sided tape going along all the edges. I removed that tape, then applied pieces of double sided tape (red TESA) in select locations. Applying double sided tape along all the edges should be practically impossible to do manually. Notes:
The original tape provides a certain level of water protection. So I’m not sure that it was a good idea to remove it. Between the pieces of tape that I applied there now are gaps, which however are not visible from the outside.
The device can be put together without tape at all, and the screen keeps attached to the body. What happens without tape in situations of stress, I don’t know.
So far everything has been working out fine for me, and my A2 already survived a couple of crashes (don’t use the ugly case).
In the endpoint method, I need to manage to connect the two points with a metal tool, right?

Yes. Note that after shorting the contacts, you have limited time to start the flashing. I think it was 40 seconds.
And i'll do the process with the battery disconnected, correct?

Yes that’s the recommended method. It also allows you to quickly reset the device, i.e. by unplugging the USB cable.

Same for me! Along the way I learned more than I wanted to. It’s interesting to see the device opened with all its components, removes a bit of the magic.
Anyhow, good luck!

Typing from my unbricked MI A2!
Thank you for the post. Everything went well. It only took me more time than it needed cause i was trying to flash the comrpessed ROM (yes, I really did it). After that everything worked fine. Remind on your post for noobs like me that you need to extract the file before flashing it!

Hello
I just try the method but me it does not happen anything if I disconnect the battery I tried with several usb cable on several computers on several USB port and it is not strictly nothing

xp wont recognize tilt unless its connected for ~15mins then disconnects after a few.

This is really weird. I plug my tilt into my computer (tried every USB port on the machine) and it does nothing. The tilt doesnt light up, the computer doesnt notice that anythings been plugged in. Then about 15 minutes later you get the 'bipbipbip' sound that somethings been plugged in and activesync opens and it tries to connect but can not, then after a few minutes of trying I get an error about nothing being connected and you hear disconnect sound xp makes when you remove something form the usb port. Tired reseting both the phone and pc with no change in behavior.
Any ideas?
I've tried the USB-PC switch which did not work.

it seems you're having the same problem I do ( http://forum.xda-developers.com/showthread.php?t=397840 )
USB to PC isn't working here too
I don't know if it's related, but I'm using L26 ROM. Are you using the original ROM?

yes original rom. I got it to sync over BT. Still not making me happy though.
Have you tried /Connections/USB to PC: disable advanced network functionality ?
Yes I have tried that with no difference.
But oddly enough its working now after I plugged the usb into the combo adapter I just got... now it works without it. Maybe it re-aligned a pin or something?

I think theres a batch of dodgy kaiser/tilts going round. My USB recently suffered many of the problems listed here and all over the forum. Won't connect to activesync, charges but nothing else, stuck in serial at bootloader. Tried on many pc's with many different cables, advanced USB functionality on/off, original SPL, the list goes on and on. I noticed one thing tho, the USB connector on my broken kaiser (O2 XDA stellar btw) looked different to my mates stellar. Mine had 5 holes on the front of it that lined up with the pins on the top. The one they sent me after i returned it doesn't have these holes and looks like my mates one. Ill try and get a pic of the difference.
Does yours have holes or no holes?
1st pic - with holes
2nd pic - no holes

but it's weird because it used to work
it stopped from nothing
I guess the holes aren't it then. Mine just stopped too, nothing changed, just didn't work one day. Does yours get recognised by windows at all? Mine kept saying usb device not recognised. This was after it was plugged in for about 15 mins or so. Incidentally, my bluetooth also stopped working at the same time.

USB device not recognized

All of a sudden I started getting this error when plugging into my PC.
I booted into the bootloader (tricolor screen) and still didn't work. It charges but doesn't connect properly.
I have searched around and read a few things (disable advanced networking, take out battery for 30 mins) Nothing seems to work.
Seems like it's a device problem... any suggestions because I'm kind of screwed here.

Hit up htcwiki.com there is a solution there, I had the same problem and it sorted itself out by buying a docking station station. I also use a three adapter (3.5mm head, sync cable and headset)which also works.
If you have the same issue as me chances are that your pda does not charge when connected either.
Hope this helps
No, as stated, mine charges when plugged in... I have a cradle, but it hooks up with the same usb cable so I can't see how that would make it better... it's just essentially an extension isn't it?
Could be a glitch in the phones software, a cable going bad, a plug going bad or a windows problem.
I've gone through a few cables and a dock, something always gets bent or something and it won't sync, I just grab another cable and it works. It's a shame the dock is bad now, it will only charge.

+1 All of a sudden a few weeks ago, my phone stopped syncing, panic, because I flash a lot . Tried everything, the list of things to try over at htcwiki was edited by me, and nothing worked, until I changed the cable. Voila ! been working ever since.
No good... not working even on another PC with another cable... and it worked before on that setup.
Um you only have troubleshot half of it. Did you say you reset the phone? LOL oh yeah my phone never worked on the original cable. Just because something was cool for one minute doesnt' mean it won't **** up the next.
Hard reset the phone. If that doesnt' work, than you are one step closer to a broken phone.
Have fun lol.

Found my problem in the last post (second to last post now )
My 2nd pin (closest to the middle) was laying flat and didn't have the curve the others had.. so it wasn't making contact. I used a caligraphy pen to get under it and pop it back up and now it works... I'm sure I'll have to keep an eye on it but for now it's working.
Hope this helps others that are reading everyone saying "it's the cable" and that isn't your problem
Thanks for all the suggestions, it had to be one of them!

Which OS on your comp. are you using Denco? I've been using vista with no problems until now and it's more than funny how this syncing issue has just been popping up all over (most likely from vista updates). First instinct with vista is updates and firewall; killed and accepted every option, still with no dice. I seriously doubt it's the cables since they worked just fine for the last several hundred syncs and now sync problems abound...any help would be appreciated brother

Yep... that pin is half of the data (1st pin is ground, last is power and two in the middle are data)... obviously ground and power are working as it charged, but if one of the data lines isn't making contact then the PC is going to be confused because it knows something is there just not getting enough info.
I tried everything, straightened my pins, shut off firewalls and security, I use Windows Xp running with Bootcamp on an iMac. I have never installed service pack 3, because I read that , that was a problem with syncing. Shut off advanced network functionality, everything I could think of.
I had sync'd a thousand times with that cable, and flashed at least one hundred roms. Then one day it just stopped syncing. After pulling my hair out for two days, trying everything, I pulled a new cable out of the overflowing cable draw, fixed, haven't had a problem since. Go figure !

HUh, It seems you might be right about a simple cable replacement. My previous cable synced me up for several hundred syncs and just crapped out one day; dug up one of my older cables and it synced just fine and now it just took a dive for charging but not syncing. Guess I'll have to hit Best Buy for a new one. Like you said; go figure. Although I noticed some new gray hairs sprouting from searching and tweaking for fix
Buy online.... Best Buy RAPES you on cables!

[Q] Stuck in low power (charging) mode, constant reboots

Hi, have a bit of an issue. My sister dropped her GXS in a pool today. she got it out and wiped it and it seemed to work fine (i told her that she should have taken the batt out immediately... she didn't) She went on then the phone died and got stuck in an endless reboot cycle. i opened it up and cleaned it and dried it, looks clean, from what i can tell. the screen shows the little refresh circle in the center, then shows the battery image for a few seconds then repeats the process (if i connect it to a wall charger, the battery image lasts about a second longer but it still restarts). it constantly restarts. and here is the problem, i can get it to download mode, but even in download mode it restarts after 3-4 seconds so i cant flash anything in such a short period. recovery does not work (even if it did i bet it would still restart after 3-4s). it starts doing this as soon as the battery is inserted.
It was running an old nightly of CM9 (about 2-3 months old)
Any help will be greatly appreciated
UPDATE:
Left it out on the sun for a few hours to dry even more off, now shows the galaxy I9000 splash screen and the semaphore kernel logo but it still restarts after 3-4s
UPDATE 2:
Dissasembled it and put it in a jar of rice, not expecting much. Took a look at the motherboard to prepare for the unbrickable mod. Those pads are TINY, i mean really tiny

That HUGE thing on the chip above is the microsd card
So my new questions are, in the original unbrickable thread i dont quite understand the instructions. IS it like in the picture near the enlarged piece numbered 1. that you must resolder the yellow marked resistor to the blue marked pads, or like in number 2. you must remove the resistor and put a wire (drawn grey) like in the picture or do you do first number 1. and then attach the wire to the upper end of the moved resistor and then to the other pad?
Congrats to your sister, looks like she killed her SGS.
Looks like the battery's not the problem, if it reboots when it's unplugged (an almost empty battery -almost empty = already shut down, but reboots for a few seconds- shows at
least unlock screen for me when I turn it on).
If recovery and download mode don't last enough to flash, it's over IMHO. And even if your warranty is still valid, water damage is not covered..
I am starting to consider doing the unbrickable mod, but i dont know whether this is a software or a hardware problem. any way to test that?

I doubt this has anything to do with Unbrickable mode solutions, anyway links to test mode tare on My Android Solutions, link below.
You problem would be most likely due to moisture shorting power and usb ports/contacts

I went over your list before posting, nothing helped in my situation, and there is no test mode on your list, or maybe i missed it. I cleaned the usb port and it looks clean, the battery contacts are also clean, no obvious damage shows, and the power on button can not be shorted because it is a potted foil membrane and the leading contacts are clean, and the button works otherwise i could not get temporarily in download mode. gonny try and mess about with adb if i can get the phone to be seen.

Problem:- Phone completely DEAD, Not Charging and NO response, only this SEC S5PC110 TEST B/D
you can only revive phone using unbrickable mode when phone is totally dead with only this words SEC S5PC110 TEST B/D, that why I said, i am doubtfull you need to use it.

I think i have no other choice, i have tried everything, my only options now are to get it repaired without warranty (probably will cost more than a new gxs off ebay), use it as a paperweight or try to do the unbrickable mod and see if that works.
Is there a possibility that a software error is constantly rebooting the phone or is there a hardware problem? I mean, could a corrupted bootloader constantly reboot the phone, no matter what mode the phone is in, like in download mode is the bootloader still runing in the background? or the kernel?
Good luck if you decide to try. I'm considered extremely good at soldering by many, I have all the proper tools including a top notch soldering station, and moving that 0201 resistor took me like an hour. One of the most difficult things I've ever had to do, and I didn't think it would work in the end. Having two irons and a microscope would have helped a lot but it's not a mod for the faint of heart. That said it saved my phone from some nasty software business.
I really doubt it would solve this problem, since it's water damage it's probably long gone. If you have no possible other option though, there's no harm in trying this.

I have a friend that does electronics and solders daily so he should be able to do it, but the big question is, is this actual hardware damage from water or a short caused data corruption and the problem is software, because the thing works, the display works, animation works, the buttons work, it only decides to repeat the process every 3-4s (it varies, sometimes it last about 6-7s, especially if i plug it in to charge, or it dies in a second or two). Could water damage it so precisely to do that, or was there a short that caused some data corruption of the rom/bootloader/kernel/whatever that makes it reboot after the boot process encounters that section of bad data, or the memory chip got corrupt. Is there a way to find out, can a log be dumped out while it is booting? my pc does not recognize anything is connected while it does its refresh battery thing, or maybe you need special drivers.

I think i have no other choice, i have tried everything, my only options now are to get it repaired without warranty (probably will cost more than a new gxs off ebay), use it as a paperweight or try to do the unbrickable mod and see if that works.
Is there a possibility that a software error is constantly rebooting the phone or is there a hardware problem? I mean, could a corrupted bootloader constantly reboot the phone, no matter what mode the phone is in, like in download mode is the bootloader still runing in the background? or the kernel?

If your phone had no problems and this problem only developed after the water damage it has nothing to do with software and all to do with hardware . I think the Phone reboots due to minute shorts in the hardware ..moisture underneath the chips could be one...you can try heating a few of larger chips...best would be to keep the phone wrapped in tissue and in a pot of rice for a week or so

i see one galaxy s like this before.
the phone boots if after u see a green battery on screeen
1.but u have to connect a strong charger (1 to 2 Amps) or a USB (1 Amp) laptop computer .
2.after connect the phone, u have to wait aprox. 30 sec, if nothing happened u ned to reconect (pull out battery , then insert it back in the same time with usb or charger plug )
3.if the grenn battery appears on screen wait to charge to 50% then press power button but not detach cable or charger
4.after complete boot , u are free to use your phone (ALL THINGS WORKS)

Galaxy S4 Active GPS Fix That Worked For Me

So My GPS randomly stopped working completely one day and so I started doing research on ways to improve it. I literally tried everything from application quick fixes, leaving my phone sitting outside for hours on end, ROM fixes... ext and nothing helped at all. I finally came across this article and, since I had nothing to lose at this point, I gave it a shot. When I finished, i got GPS fix within 2 seconds! This option is not for everyone, I really suggest making sure that the software/application fixes don't help first because taking apart your phone certainly has its risks but if you are like me and nothing has been working, there is hope!

Check this article out and give me a shout out if it worked for you too.

Keep in mind that the disassembly process is slightly different since we are talking about actives, but I just looked up another article showing how to remove the back of the active and jumped to step 3.
Thanks man, you nailed it! (I just signed up here to show my appreciation for your post, because otherwise I would probably not have come across the solution at all)
I had been somewhat unhappy with my s4a's gps performance since I bought the phone. It usually worked, but often needed 2-3 minutes for the first fix and often lost signal for a few minutes intermittently. Today I opened it up and noticed that the GPS antenna (or what I believe to be the GPS antenna) had apparently never been properly connected to the board. The springs had left no marks on the other side of the contacts (completely blank and spotless), unlike in all the other places where there are connections from the board to the midframe. Then I put a small, folded piece of tinfoil in as suggested in the link you posted and woohoo, only a few seconds now until I get my first fix outside and it can sometimes even get a fix inside my flat (a few meters away from the window at least, with 3 more floors above me), whereas before i had to hold my phone out of the window for that.
Now I am also curious whether or not that will reduce the heavy battery drain of gps logging while hiking in the mountains.
Also thanks for the hint about not following the disassembly instructions directly, since it seems one can easily break the midframe if unaware of the plastic clip above the battery holder. I used these instructions:
h t t p s : / /uuu.ifixit.com/Guide/Disassembling+Samsung+Galaxy+S4+Active/37470
With them and the appropriate tools, even I (theoretical physicist with thumbs on all fingers) found it easy to carry the task out.
(Sorry for the urls, I am not yet allowed to post links here, so replace uuu by www)
Also note that I believe that the two antenna contacts shown on the pictures of your instructables howto are the wrong ones. That should be the 4G antenna, wheras the GPS antenna is on the opposite side as shown here at 3:30:
h t t p s : / /uuu.youtube.com/watch?v=zm4f2XjQLAM
(at least that is where I put my tinfoil, maybe I am wrong and the effect I experience soley stems from me tightening the screws harder than they were before?)
Alright, now excuse me please, I have to catch that Pokemon which apparently spawned in my bathroom
My pleasure, glad I could help!

Much obliged for that!
I was able to download a service manual that appears to be an inside document bundle of Samsung. The GPS antenna is named 'ANT200', and it is in fact, on the other side of the PCB (left size, when looking at the PCB from the battery side of the phone, with the rear plastic assembly removed.)
Previously I tried the GPS fix by adding aluminum foils on the two other antenna connectors, which did not fix my GPS. adding the alumium on this single connector made a difference. (I actually also took it back out, to make sure this really helps.) However, still takes a while to get a fix. at least with my phone held outside my apartment.

Getting "Charging blocked due to moisture" error every time I try to charge

I've been getting this error every few days since I got the phone, but now I've gone a day without being able to plug it in (this is why I only buy phones with wireless charging). I tried rebooting, shutting it down for a while, etc.
And it's gotten nowhere near water.
Any solutions for this? Do I just need to take it to a t-mo store and ask?

I'd already be on my way back to the store. Besides, it's supposed to be water resistant- take it back let them figure it out

I got the same problem since 3 days ago, I think it is a software bug, as my G6 charges when it's off but gives me the same error when it's on! try to charge it while off. I am looking to find the actual problem, if anyone know why this happens??
Solved for me

I took my phone to spain and it had loads of sand on it by the beach. I couldn't charge due to the moisture warning for 3 days. Eventually i found a solution. I loaded a bathroom sink with about 2/3rds water. I swilled only the port area in the sink. I then dried the phone as well as possible. I screwed a thin tissue paper up and dabbed round the port. I then found a rectangle piece of card (it was a clothes price tag) it was probably 1 millimetre thick and i pushed it in deep into the usb port to aid cleaning using the corners of the tag. It solved the issue and didnt break anything and cleaned out some of the deep sand and cotton that wasnt drying at 30 celicus heat this week. Saved me claiming on my insurance and the headache of installing all my apps etc. Try it, but be very careful with the card tag as you dont want to break any terminals in the usb slot. I used this forum to try and find a fix and i couldn't, hence me putting my solution on here.

I got mine working via a similar method & haven't had the problem since. It's only given me the warning once since then, and a reboot fixed it.

Aaand my phone is doing it again. 24 hours and unable to charge except wirelessly or by plugging it in when it's turned off. Trouble is, I'm going out of town tomorrow and am counting on it for GPS.
edit: there's some relationship between the moisture alert and charging settings in developer options. Some people seem to be able to fix it totally that way, but I am seeing only partial success.
Same has happened to me. I am resetting right now to see if this works.
Any luck? They are replacing mine, but it's going to take a week or so.
This has been occurring on my device for a while as well. Usually the reboot while keeping the device plugged in would reset the software bug and charging would continue like normal. Now I can't get the phone past 4 or 5 percent charged. Every time I try to power off the device and charge that way, the phone automatically turns on after it gets to about 5 percent, and the cycle repeats with the charging blocked due to moisture in the usb port error. This is certainly very frustrating, not to mention I also had the weird camera glass cover anomaly where the glass shatters outside the lens, rendering my standard camera lens unusable with a foggy/smoky effect due to the glass on the outside cracked. I loved my LG G4, but I don't know about LG after this debacle of events. I too have tried changing charging settings in developer options with no success. I will be taking this back to T-Mobile tomorrow unless some miracle happens.

Nope it did not work. My next trick is to put it in a silica bag if that does not work I will take it back to T-mobile.
I keep seeing people come to this thread with hopes of a fix. I highly recommend you return your device if you have this issue. I have taken my G6 through the ringer at the water park (swimming, water slides, etc.) and have not once received this warning. It must be a defect.

Caught between a rock and a hard place there. I don't know if you're familiar with some G6's getting that crazy spider crack on the camera glass, but that freak occurrence happened on my device as well, so LG won't validate a return on the manufacturer's warranty due to that, and I really have no way of doing a factory reset since the phone won't charge anywhere past 5% while the phone is off before it turns on automatically at that point. $175 to get it replaced under T-Mobile insurance. Never thought a device so highly praised would be such a disappointment.

So T-mobile wanting you to pay the $175 fee? Did you tell them you put it in the water?
There was no contact with any significant amount of water at all since I got the phone, but thanks for adding your skepticism.
So I am no longer getting the moisture error I am getting the "Power Supply Tap To Change USB options message" and a different battery icon error which I think is making me have high phone idle.

I had this issue, and sent it in to LG. They told me there was a software glitch that once that alert was activated, the software wouldn't turn it off. You can prove this by restarting the phone, and plugging in the charger before it boots back up again. It will charge perfectly fine, but then if you unplug it and plug it back in, the error comes back. Send it in, they'll fix it.

For what it's worth, that wasn't the case for me. I tried every variation of plugging it in on/off/rebooting/tweaking every setting I could find or anyone suggested. The last time I had it happen, it took 3 days before it let me charge any way but wireless. Finally I went to the T-Mo store and they spent five minutes on it before ordering a new phone. That was a month ago. Knock on wood, I haven't yet seen the problem with the new phone.
ughhhhh.... tried everything. I absolutely hate having to reload everything on my phone!
Yup, last LG phone I'm buying. Software error or not I just came from a bootlooped LG G4 that I had to fight tooth and nail to get replaced and still wasn't free ($20.) I've never damaged a smartphone in the last 7 years of owning one. No cracked screens or water damage. Not only that, in an attempt to charge the phone while powered off it charges slowly AND forces my phone back on even though I select power off. Seriously people, stop buying LG.
Replace port charger this fix issue whith moisture charging blocked! i test this works fine
