Please help me unbrick my Mi A1 - Xiaomi Mi A1 Questions & Answers

I decided to go back to stock rom a few weeks ago after using Lineage, I obviously was an idiot because while the stock rom flashed perfectly as soon as there was an OTA update it went into the bootloop, couldn't flash it as the bootloader is locked.
Tried using ABD fastboot but it wouldn't unlock the bootloader, the mi unlock tool wouldn't do it either.
I now have an EDL cable but can't seem to get the phone into EDL mode to flash it. I connect the cable to the PC, press the button and plug into phone, the phone simply goes boots to the normal charging screen that presents when you plug it in whilst the phone is off. Nothing shows up in device manager etc.
Anyone help me unbrick it?

If EDL Cable is not working, try "test point" method. It will definitely work.

Thanks, that was the next step, which did work, but I've damaged it taking it apart. So all a bit pointless in the end!

Not really sure what I've damaged either since it doesnt seem to be a part of the screen or back plate. So not sure if it's worth getting it repaired.

I damaged my phone too yesterday while I was trying to open it so I could unbrick it but I don't care. Having a working phone (the way I want it) is more important than having one with stock Pie in immaculate condition.

It's called "middle frame housing/chassis" which holds all the components together like display, motherboard, sub board, battery etc. You have chipped off the plastic bezel/border of the housing that surrounds the display and protect it from breaking during fall.
It will not affect the functionality of the phone but will definitely make a big dent in your pocket if your phone falls from your hand / pocket.
I will suggest you to replace the middle frame as soon as possible and until then use it with extreme care or with a good quality case.
You can find it on Aliexpress or from your local spare parts dealer. It will cost you around 5-7USD.
P.S. : Don't try to do it yourself, get help from a technician(2-3USD) as they separate the lcd and frame using heat of lcd-glass separator machine.

Thanks, it's okay the price they'd charge to replace it would be around £60 here, even if I supplied the part, I can buy a new one for £60ish on ebay so it's not worth it.
I ordered the Note 8, the plan was to pass thr Mi A1 on to someone but I'll just write it off.

£ 60 is too much for this. Here in India I can get it done at just INR 100 which is equivalent to around £ 1.05

BUY/SELL a broken Wizard! Protect our dying breed.

do you have a broken wizard you'd like to sell? simply put it under www.ebay.com and signal the broken wizard offer (THE LINK!) under this thread - specifying the type of defect.
There is a number of OTHER broken wizards (like mine!) that could be repaired by recovering parts from others. And very often we could repair more than one - so after you've repaired yours you could try to resell the remaining pieces.
So, anybody having a broken wizard: follow this thread and we will ALL save money!
As you know, the service manual is very detailed and allows easy replacement of many parts: screens, keyboards, mainboards, stylus holders...batteries!
anyway, we are not anymore under warranty....right?
Comments also welcome, since keep the thread high in the list...
Anything YOU NEED?
Hi,
all those in need of parts could also post here...i desperately need one LCD PCB - since the connector on the flat cable between the LCD and the PCB went bad and my display doesn't work anymore/ after months of shaky performances...THX
anybody got a screen around?need the lcd+digitizer. im not sure yet whether its a gold or black connection, will check later on, but just wondering if anyone has an lcd around..
where could i get the service manual?
anyone know where I can find a switch? Yes, a switch not the button. Long story
Hi,
I have for sale the LCD and touch screen. However, it's more complicated.
My touch screen was cracked but the LCD was good so I bought a new touch screen and tried to fixed it but I was not able to connect touch screen to the LCD (solder the tape?). So I quit and bought a new LCD with the touch screnn. So now I have an used LCD and a brand new touch screen for sale. If you are good in fixing things, I'm sure you will have fun
Let me know if you need some more information or pictures.
Peace,

My son's Wizard/Cingular 8125 Died
I'll be listing my son's Cingular 8125 later on today on Ebay. It appears the motherboard went "belly up" on it. . . just 3 weeks out of warranty. At least -- from reading some other threads on the forums about the same type problems, that's what I'm surmising happened to it. It wasn't dropped, kicked, sat on, run over, etc., etc. -- it just shut down while he was on the Internet, never to be revived again. I tried switching out his battery with my fully-charged battery to rule that out and tried a few other ideas I found on the forums -- NADA.
No blinking LED when plugged into the wall charger and the PC gives me an error message that the "USB Device has malfunctioned" when plugging it up to the USB sync cable. He had been running the WM6 Underground Edition ROM for a little over 2 months without any problems. It's also one of the original G3 chip phones.
Thought I'd post on here before listing it to see if anyone is interested. PM me if you are.
(MODS -- if this isn't allowed, please remove the post, and I'm sorry)

What do you mean? Did the actual button break the one inside soldered to the board or just the case button that is used to press on the real button?
I broke the actual button trying to put the case back on and I got an old board I am desoldering the buttons from. If this is the case then I could probably send you one.

Getting no signal after a hard fall

Anyone can help me, my TyTN fall from my home stairs and I can't get signal after that.. I checked at the "Device Information" in the setting and it shows no Radio ROM.. so I try to install the radio ROM but im getting error during the installation.. I believe it is the hardware faulty and appreciate if anyone knows what is it and where can i get the replacement of the hardware..
FYI.. my TyTN can still be operated, its just cannot get the signal..
Thanking everyone's help in advance....
i'm not sure if you resolved the issue or not, but i'm selling an AT&T 8525. I'll sell it to you for $300 shipped as long as you live in the usa.
I'm not familiar with the insides of the phone, but there are a few options. 1, open it up and find out what's wrong. There could be a connector or circuit that broke and would only require minimal effort to fix. 2, find out if HTC can repair it for you through non-warrenty repair. 3, buy another phone online(like through ebay) that's only good for parts and use it for repairs.
Of course, if you don't feel up to opening it up, you could always find a friend or repair shop that might be willing to try.
ok one of these days i am going to write a book on how to re-attach antennas as the one in the TyTN is similar to the herm100 i presume
you cant miss it, its a big gold rod that slots into a V clip on the main board, a serious jolt could pop its loose, but it wont take much to pop back in, just be careful when you put the cover back on
Yep, there it is top left

And here it is disconnected.
However, I'm not convinced there is sufficient space available for that pin to disconnect while the casing is in place. My fear is a more destructive M/Board fault.
Mike
he could have shatterd the V clip off the board
It's more likely the golden connector from the picture got disconnected than that a board or chip broken. It would require the CASING to break in order for the board to break.
Open it up, take a chance. It's not so hard, just scary the first time.

We could take bets on what it is! No that wouldn't be fair would it
I agree it's worth opening up to check the connection. Depending on how hard the fall was it could be a variety of things. Don't agree that the motherboard can only crack if the casing breaks though - I've seen many examples of cracked m'boards and hardly a scratch on the case.
The OP seems to have disappeared anyway!
Mike
Thanks for the replies.. i've just been busy lately..
Will try your suggestion later to check the golden connector 'coz i've been opened it up many times already so its not a scary things to do for me...
will report back the results
hey again mates..
I already check on the golden connector and it seems fine.. everything is in contact and no physical crack was found or whatsoever...
I believe my TyTN is having the same problem with the one in this thread because I have similar symptoms like
1/ i can't flash radio back (the process hang in a middle of the flashing progress).
2/ there's no Radio & Protocol version in the "Settings->System->Device Information"
3/ no IMEI in the "Settings->System->Device Information"
Anyway, Is there a way to write the IMEI no. for the TyTN? maybe if there is an IMEI no. in the TyTN then can I flash the radio ROM.. i think.. and its worth trying (if possible) . or maybe its a hardware problem like in the thread above...
same wif my herm100 hard fall and no more signal
think tat is crack in gsm chips,u just look forward on gsm chips to replace ur old 1,then should be fine and work well ^^

What can I do with a screenless device

Beginning of the year my younger brother gave me his replaced HTC Touch from Telus (which I believe is the Vogue - correct me if I'm wrong). I used it for all of 2 weeks before it cracked in my pocket (huge rage moment).
I've got a Sapphire now, so it's cool, but I just found this busted phone. I still boots and I can hear sounds coming from it, but the screen is still toast (of course).
So, is there anything cool or fun or useful I can do with it? I'm not afraid of getting dirty or technical with it.
Here's a picture:

get a new screen?
Is it worth the cost? And where do I get one?
(I post before googling, mostly to get more responses, but off I go...)
I found a couple of replacement parts. I guess the screen for the Vogue and Elf are the same.
Now theres two things here:
OEM LCD Screen Display $50 US
https://www.gsm4world.us/htc-touch-oem-lcd-screen-display-d-01230_238.html
OEM LCD Digitizer/touch screen $20 US
https://www.gsm4world.us/htc-touch-oem-lcd-digitizer-touch-screen-d-01246_238.html
What's the difference? I'm fearful of the second one only being the touch input, and that I'd actually need to replace the screen, which is $50 US (and I'm in Canada - pushes it high enough not to be worth it).
Anyone got a broked model with a working screen they want to send me?
I was hoping I could do something without a screen. Like run a TF2 server or host a file share. (I hope you get the sarcasm)
you could sell it... check ebay for the lcd screen and you might save a little money.

can you access the internal memory using active sync? if you can, you can place a .lnk of any program installed on your phone into the /windows/startup/ folder and have it run automatically on boot. trying to think of a program that would be useful without the screen, coming up with blanks right now.

Not sure, I've never done this before. Perhaps I'll try some of that this weekend. It's not really important for me, just something cool to do.
Screenless Device
interesting.. Lol.. I am in Canada looking for a Touch Vogue Cell (doesn't matter what provider as I am pretty sure they are all the same except for Roms and Wifi. )that I can use for parts.. My Touch sensor died, was hoping to get one that was mostly in tact as I can use the touch sensor and the Casing to fix mine.. If you want to be able to do stuff still you can actually, get ActiveSyc working and use My Mobiler and you can do everything you need to through a computer as well.. Is how I do most of my major stuff like txting and settings etc..
Just some random thoughts..
PM ME if you want to talk
I mostly just want to use it as a phone. I've got a Magic from Rogers that work pays for, but my girlfriend's phone is crap. I've seen screens for these things for about $50 around... I may try to take this apart and see if I can get the screen off. If I can, it may be worth a shot.
Are you saying you'd be interested in taking this shell off my hands? I'm pretty sure it's only the screen because I can turn it on and still here things and clicking and whatnot.
continuing on tatnai's thought....I guess you could set it up to act as an ipod shuffle listen to mp3's without a screen. you could have the music link boot from start and set it to be the only thing that runs and bam you have an mp3 player. Also can be used for a paper weight
Note that taking apart the Vogue is hard without the right equipment. You need a fivesided screwdriver (T5) as well as a plastic prying tool. I recently replaced my digitizer and it was fairly easy with these tools (they came with the new digitizer)
If you want a guide to disasembling the vogue, this is what I used.
http://mikechannon.net/PDF%20Manuals/OSeven%27s%20Disassembly%20Guide%20to%20the%20HTC%20Touch%20-%20Elf%20.pdf
Hey, thanks a lot. I'll keep that guide handy. I don't have a plastic tool, but I should be able to make due with some other things around my tool box.
I personally thought my Vogue is one of the easier phones I've disassembled (had to air it out and redo the LCD flex - water damage). You just need a T5 which you've probably got in a screwdriver set somewhere.
Replacing the display itself would be *very* straightforward - disassemble, remove and reinsert one flex cable and two screws, and reassemble. You aren't going to get much out of it without a display, sadly.
As a note, I had the most trouble putting mine together because of the SD card door on the side - try not to let it fall off during disassembly as it's got some rubber tethers that are mildly tricky to put back. It's not exactly a disaster if it comes off though - it took me maybe 30 seconds. Was frustrating though.
Should be good as a card reader, microSD of course.
Get a big enough microSD card and it's a portable drive...slow and there're cheaper and/or faster alternatives...but something to brag about.

HD2 Opening Instructions for dummies (only till Main PCB)

Disclaimer: Opening your HD2 will result in your warranty becoming VOID. Any damage to your HD2 as a result of following this walk-through is not my fault and was because you have large clumsy hands. If you want your phone repaired professionally without your warranty voided, send it to your supplier.
Tools you will need:
- HD2
- T5 screwdriver
- Tool kit for Phone/iPod/PSP (available on ebay, pictured below)

1) To start off with, turn off the phone then remove the battery cover along with the battery, SIM card and SD card.
2) WARNING! This next step will VOID your warranty. Remove the 4 screws using the T5 screwdriver.
3) Now comes the fun bit, stick the suction cup near the top of the screen and insert the blue tool (for lack of a real name) between the screen and casing.
4) Once the blue tool is in you should be able to pop the screen out one side at a time as there are two sets of "hooks" that hold it in place. You can pull on the suction cup to make this process easier.
5) Now that the top bit is out you need to run the blue tool down the sides of the screen to loosen it up. Then pull on the suction cup and it should separate quite easily.
6) To remove the main PCB you need to remove 3 screws using the T5 screwdriver. There are 6 connectors on the Main PCB, 3 on the top (yellow) and three on the bottom (red). You will also need to remove the copper shielding, you can do so by carefully pulling it off taking care not to deform it as you will need it back it the same place when you reassemble it.
Reassembling it is just a reverse process of the disassembly with the exception of the volume buttons, I've found them quite annoying to hold in place as you push the screen back and had to try multiple times to get it right.
That's all I got up to so far, if I get a weekend off I'll try to go further and do a complete guide, along with replacing the screen. If anyone has any suggestions/improvements please let me know as this was a little rushed.
Notes: You can use a plastic screwdriver if you don't want to buy the blue thingy but it may damage your phone. On my first opening attempt I used a screwdriver and there is slight damage to the top where I inserted it. Second attempt with the blue thingy and there is no additional damage and the screen was much easier to remove.

This is very informative. Thank you.
Very well done. Thank you for your time. I do hope I will not have to come back to this guide anytime soon .
Many thanks, but can you do a youtube video of this? I tried to do this using exactly the same tools, but i didn't manage to remove the glass unit from the backcover although i used the blue plastic tool in the same way.
When do you have time to look at the screen? I've got all the tools ready, and the replacement screen. Hope to see some guide somewhere soon
Sorry, been real busy as of late. May do it in a month or two. But there are some videos that might help you here.

Thanks. My HD2 has a crack running from the battery holding place and all the way where the screen starts. I was gutted but looks easier than thought now , Thanks to these instructions by you if I buy a new back casing cover.
Thank you, Maybe now I can start thinking more seriously about replacing my LED to support more colours
Very nice quality BTW
If I may say well done I have had to take down my hd2 twice for screen replacements and I can't really say I'm proud of it.
My HD2 only has two screws. Is the uk casing different to the US one ?.

You should seriously think to get your touchscreen replaced, most likely you cracked it in your attempt to open your phone.

SM-T580 Black Screen

Hello,
While listening to music today on my tablet, I noticed my screen was black. I tried turning on and off with no prevail. I could still hear music before I tried to boot into recovery.
After booting into recovery the screen would still not turn on and I no idea where to turn.
My device is rooted and running custom firmware.
Thanks in advance
Let the battery drain out completely or open up the tablet and disconnect the battery for 5 minutes. That may fix your problem. There is a youtube video on that.
Sent from my [device_name] using XDA-Developers Legacy app
Thanks a million!
It worked! I searched on YouTube on how to disconnect battery and it was so easy I was able to do it with a credit card in the front seat of my truck!!!
Thank you again for the extremely fast reply
We are facing this problem in the sm-t580m model - in a few tablets (around 14)
May you pass us the video please professor?
Opening tablets!
I’m not able to post the video.
But I Googled, “how to open tablet” and found some redneck looking guy opening it on his front porch.
I use an old credit card to open it from the edges. And i actually went back to the credit card because the tool I used from a phone repair kit kept breaking.
If you need I can make a demo. Let me know!

Thank you, a demo would be useful.
we used to use the cards to open tablets - but not samsung- it's difficult i saw it.

After opening, remove protective tape and unplug the ribbon cables (one at a time). A smaller one and a longer one laying over whole battery. Wait five minutes, plug back in, and reassemble case.

Don't use metal prying tool, especially for novices because you will damage the LCD frame and case easily. Do carelessly like the guy in video will easily damage the case.
Remove the battery first is important step because disconnect and reconnect cables may cause a short circuit if you don't insert them properly.
Remove the white and small cable is not necessarily because it connects speakers and home button to mainboard. The main problem of black screen is from a loose LCD cable, like this one, the line on the cable is below the line on mainboard which indicates it got loose and you'll have a black screen.

So someone removed battery cable and other two cables and think it fixes the black screen problem is not correct. What he did actually fix the problem is reseating the LCD cable.
You should discard the OEM tape and use your own tape to secure the black LCD cable, use as much as you can because the connector is too weak to hold a long cable like this one.
Awesome
Thanks for the insight..!
I admit I don’t know exactly what I’m doing, but watched some videos on how to solve the problem.
I do notice though that after the screen blacks out, if I leave the tablet on until the battery fully drains and plug it back in, it corrects the situation as well..? Idk what that is about but thought I’d throw it out there.
Anyways thanks again for your help and insight!!!
Reseat the battery might fix the black screen but 90% of the time it’s from the loose LCD cable.
Normally, I reseat the battery first, plugin and the battery icon doesn’t show up, then reseating the lcd cable is next step. Always disconnect battery when doing reseating cable to avoid short circuit.
Many many thankz for the info Beut, it fixed the black screen on my sons Tab, after opening the tab i checked the lcd cable and voila the line was not straight. I pushed the cable back in,
so that the line was really aligned, tried the tab and got a lot of kisses and hugs from my kid .
So many many thankz from a happy Dad and Son
Thank you, I have been able to recover my T585 too, I reseated the batery and lcd connector and the black screen problem was fixed.
