Data recovery from a dead CPU? - Huawei Mate 10 Questions & Answers

Greetings,
The device was water-damaged, battery + screen + Charger IC were replaced, and it worked for 2 days.
During the 2 days, the charging was very slow. And it consumed 2-4 times the ampers it stored (I can tell by charging from a power bank with % indicator ) - a rough estimate.
I left it on the charger, at around 70% charged, left for a few minutes, and went back to see it completely dead.
4 days from a technician to another, no one was able to boot it up. Their final conclusion was that the CPU is damaged. And the device is non-fixable.
I heard that if the CPU was damaged then the internal memory is lost, too. And that I can't change the CPU while keeping the old memory as if they are digitally signed.
Assuming that the CPU was actually damaged, what are my chances of recovering data? Is it true that the CPU is irreplaceable (while keeping the internal memory) ?
Btw, according to them, there were no visible signs of burnt ICs.
The device in question is Mate 10 Pro, but I don't see a dedicated forum for it so I am posting here.
Regards.

You can probably buy a broken screen mate 10 pro online really cheap. As long as motherboard works all good, then send it a repair shop that does micro soldering and have them remove nand chip from the dead motherboard and transfer it over to the new one..
Cross fingers and hope that it will work alright which idk if it will...
The chances are that it likely won't lol . I'm not sure if chip might need reprogramming, whether it's paired to the CPU or whether you'd have to swap over some other parts as well.
It's likely gonna be really costly to do this. 50$ maybe for a new motherboard but expect 200/300$ at least for labor involved. Plus not every micro soldering shop even has the right tools necessary for all of this.
You're looking at 350$ + without even knowing whether it'll work or not in the end.

[Q] Xperia x10 motherboard problem

The problem:-
1- restarts many times.
2-randomly shut down when i open Wi-Fi or apps or use it for more than 5 mins.
3-can't turn on sometimes and can't turn on using charger , only pc companion.
4-Burning Smell.
i know there's another thread talks about this problem but pleaese it's a serious common problem , i bought the mobile yesterday and i can't replace it , i've seen this post in SE forms : -
............................................................................................................
It cost about more than 2 hours,and i sat near the engineer looked at what he was doing,everything.
1. He said before this one,he has fix 4 x10 with the same problem.He checked my phone and told me he must take the phone to parts,i agreeed.
2.The restart problem is neither a software problem nor briefly hardware problem.The reason most likely is welding procedure .Between X10's CPU and the chassis on the M/B there is no bayonet(i'm not sure it's the right word), so the closeness of them only depends on colophony(another word i use google to translate it) and solder (the third one).He said when x10 is koncked or bumped,fissure or something others may appear,and when CPU runs at a high level,the ammeter shows a number above 200mA,you can think its fever.Because goods expand with heat and contract with cold,here comes the flexibility.It may influence the contact between cpu and chassis.So the restart happens. He get the CPU off M/B,clear and rebuilt solder on them very carefully,and packed everything back.THIS COST TWO HOURS.
3.When parts became back to a phone,I push sim card,sd card back,truned it on,it booted successed.Then i run the Backup and Restore app,no problem.Before repaired erverytime i run it, the phone restarted.view www web use the brower by 3G, opened servel windows,no problem;Played Asphalt 5 for 10 mins,the phone became hot,still no problem.So i paid for it and left.That cost fuxk 500RMB,nearly 100$!!!!!!!!!!
4.When the engineer was soleing it, i talked to him,he said G7 also has a lot of problem,G7 use the smae CPU as x10,it also may restart.
............................................................................................................
anyone tried this?????
please if anyone has fixed this problem (i know i can change the motherboard but it cost alot , I need Electric solve) . and it's not a software problem at all and n ot in the battry .
this is the best forms for PPC's so i don't have to post this in every site so better sign up and replay please maybe someone can help...
64 views and no answer -,-
and btw the phone works well when it's cold but it shut down when it's worm or using Wi-Fi or Calling . so to re-operate it you need to put it in air conditioner then but the battery back and switch on
So far no problem.
By the way the phone had no warranty?
yea , i bought it used and it looks that someone bought it from china and sell it here so the warranty doesn't cover my country.
thanx for telling me that x10 doesn't have another factory problems.
i send it today to one of those small repair places , they said the IC's are burned because of short circuit or something like that so we'll see what will happen tomorrow.
it cost me around 100$ but it doesn't matter as long it work.
sorry to say it but you buy cheap, you get cheap. might have to shell out for some repair work or ditch it and buy a new one. hard luck man.

my friend I am sorry but there is no quick fix for something like this. To repair SMT type circuit boards you need a clean room environment and also some very expensive equipment. My advice is to get a new handset, there are a few people on here that need some parts for their phones and you can off set the cost of a new handset that way.
thanx for the advice , i'll replace it with one that works and with a warranty . this will be my last time buying cheap S***, i really like it and i hope they release android 2.0 soon for it.

As I said there are people who need parts, so it will not be a total loss!
where are you located? I need a few bits.
Tomorrow i'll sell it with around 150 dollar, i'll replace it with another X10 but with WARRANTY this time
just found this thread and it seems to describe my problem with my x10. If the crashing is heat related would using a cpu underclock help?
http://forum.xda-developers.com/showthread.php?t=831658 for more info
my phone doesnt charge the battery, but charging animation is playing, gave to service centre,they told motherboard replacement,but that told we dont do for the handsets without warranty.... pls help how can i sort this prob.
I don't agree with the first post, I had this problem too, and the problem was bad, but as soon I as I flashed with the latest firmware, that problem seems to have been fixed, gone by 2 days without any restarts.
i also have this problem.
The worse is now my charged battery will become red low batt at first and recharge itself back to normal without plug in power...i think i just solve the world energy problem here.
May have fixed the problem, for a bit.
I bought one of these used (x10a), I basically got ripped off by some guy that must have known about the issue. Anyway, I tore the phone apart down to the screen, I left that intact. I cleaned the housing, motherboard and sound jack with compressed air (lightly), cleaned contacts that looked a little dull. I noticed the foil covering the CPU and other components was a little askew and there were some heat bubbles forming. I used a mini spatula as a squeegee and got rid of the bubbles, cleaned up the edges around the foil to insure they didn't contact their neighbors and put the thing back together.
Before this I could use the phone for a call for longer than 2 minutes, the second I ended the call it would crash/reboot. Same with playing games and listening to music at the same time. Movies, forget it. I don't want to curse it because it has only been a day, but no crashes yet and I'm doing/running everything I can to try and get this thing to crash. If it was the bubbles contacting other metal in the chassis then they will probably return sometime in the future.
Who knows.
For now, I say it's fixed. I hope.
I downloaded the schematic and disassembly, reassembly instructions off the net.
UPDATE: Cleaning did not work, I really didn't think it would but it was worth a try. I did however rebake the main board in my convection oven for 10 minutes at 210 degrees Celsius and it worked. I have uploaded videos to youtube. If you're like me, no warranty and don't mind tearing things apart. Check out my videos on youtube, do a search for MrSpywhite.
I had the same problem and SE replaced the motherboard.

That sounds like good news, I have a friend with a similar problem, but his phone has the same behaviour faster than yours... did really work? any problems after the bake? (mic, speaker) ?
Sorry for bumping in a old thread but I am also facing the same problem i guess. Anyone got it to work ?
The motherboard is costing me Rs.8000 ( 160$ approx ) and its a 2 yr old phone. Cant spend that much now on such an old phone.
This solution might help on that cases, as main reason for such things are Pb free soldering (small balls between CPU and MB).

Non-removable battery - Dealbreaker?

Hey all,
There doesnt appear to be a topic specifically on this(I have searched) so I have to ask.
Does this cripple the phone for you?
My personal situation:
Have an x10i
Long time SE user
Planning on upgrading in the next month
The two cons with this phone for me are the lack of an SD slot, and the battery. With google music and the like I can totally deal with the SD failing. But the battery, its got me totally conflicted. Ruining a dream phone. I've had several SE phones and their programming isnt great. Even just the other day my X10 crashed twice and I had to pull the battery. This is what worries me.
Thoughts?
Scratch
No and no
The phone has built in reset button combinations (hard-coded so will always work). I don't see other than that, why the battery thing is a problem Unless you plan on keeping the phone for a very long time (read: to the point where the battery cant hold a charge) it's not worth losing sleep over. There's a few threads on how to remove the battery I believe as well, and by then your warranty will be up anyways, so who cares if you unscrew the back .
The no SD thing is also not a problem with the amount of internal memory available + USB OTG support

Ah jaysis, there were big rants about this on another forum and there was ZERO mention of the fact that it had a hardcoded reset.

1st. The 32gb seams to do me at mo (may not be good for app hoarders) at the end of day the battery will die before watch 1 season of (e.g family guy) or half way through 1 good space hungry sd using game, so why do you need it full up. 2nd. Batt is not a problem unless you carry spares around with you. Hard reset = (power button and vol up) works same as pulling the batt out. this was my same worrie when read about it myself at first.
well, i forced a bootloop to test the "hard shutdown" and it works
Think about the HTC X devices, they are only coming with 16gb and dropbox as backup.

That's the one s. The one x has 32gb, just like xperia s.
About the sd card slot. I really don't miss it. 32gb is more than enough memory for me. In my old phone (htc desire) I had a 32gb sd card and never took it out of the phone. If you need some removeable memory for whatever reason usb on the go will do, but I doubt I will ever need it.
The the battery. Well running around with spares is not something I ever did. I usually just bring a charger or usb cable if I'm away from home for a while. If you are in places where you have no access to power, you could allways buy an external charger. That would basically do the same job as extra batteries. If you're worried the battery may wear out over time: it is removeable if you unscrew the back. So It can be replaced if needed.

Yes, the X has 32, same as us. Given how much stuff I have installed I would think I would have less space, my 4S was a 32gb and it was mostly full with half the apps and a few more pics and videos.
+1 about the charger, I have some old Nokia N882/N95 micro USB cables that I use as backup and might even buy:

Desire X Bricked :(

OK, i got a desire x off a friend he bought it new two weeks ago but he went on holidays and i swapped him an iPhone.
The phone is unrooted. Last night i sat down while it was in my pocket and my car keys cracked the digitalizer. I was extremely annoyed so i left it down on the table. I had installed a new android launcher team that day but when i had the phone in my hand after it broke i remember the battery was a red icon, but i was low im just mentioning. Anyway long story short it went dead i brought it up to my room and plugged it into the wall charger. The orange light came on so i went to sleep. I woke up and the light was still on. I plugged it out and the light went off but the phone still wont boot nor go into recovery, safe etc.. Can someone please help me as i don't know what to do.

First of all, your friend's Desire X is surely bricked. It would take a more direct approach than damaging the digitizer or installing a launcher to actually brick the device.
From my knowledge of electricity i would say the digitizer is short circuiting internally which may explain the reason the electric current from the charger flowing constantly somewhere else other than the battery. This is evident in the fact when we have a mobile device which has almost no charge, and after we plug it in and start using that mobile device, the AC charger keeps the device running and also the screen on, until the battery gain enough charge to take over and start storing charge itself. The scenario seems possible to the extent that your digitizer is short circuiting internally. And it is preventing the battery from gaining enough charge to take over.
The next possible scenario is that the battery has got pushed inside as well. But for this to be possible your car keys have to go through the plastic and reach the battery to be flattened by force internally.
So what you can do is go to any authorized service center and explain just what happened. Of course they would charge you cos this would be out of question to offer warranty. Just replace the digitizer and check.
Good luck.

So if you can get a look at how much damage was done, maybe you can repair the digitizer only and be done with.

My #1 suggestion is for you to take the desire X to an authorized service center and let them repair it.
Because if you do any other damage while trying to take apart the device, it may damage parts which were not damage originally. This would cost you additionally then. So let the repair guys worry about it. As it is you have enough stress i can understand.
Unless you are sure about disassembling the unit yourself, i DO NOT recommend it. The manufacturers are now sticking to new methods of minimizing the size of the body. So this means a lot of glue and other adhesives between the body, lcd panels, digitizer instead of the traditional hooks between the plastic body and screws to hold the parts together. Believe me, removing away glued parts is very risky if you don't have the proper equipment to raise the temperature to certain degree to melt away the glue or adhesives.

As i have seen the internal of HTC Touch, Diamond and HD2 only what i would suggest is for you to check for any damages to ANY other parts of the device. This includes
1. the plastic body
2. the mainboard
3. the battery (by default it should be a uniform surface) so check if its pushed in any sides
4. if the lcd has been pushed from the inside leading to an external mark on the back side.
All the best
**edited**
Just had a quick look through my desire X
There is not circuit board on top of the battery compartment. The mainboard is just on top of the device.
So i am sure it is just the LCD/Digitizer
Hm, there were in fact three reports about similar issues on the German android-hilfe.de forums, where the device actually wouldn't turn back on after the battery had reached 0%, the device had been shut down automatically, and had then been charged as usual. Would be interesting whether that issue was a more general hardware/battery failure, and the physical damage reported here was just 'coincidentally', having no direct impact on the battery.
To be honest, I'm quite concerned about this - I always used to let my old Samsung device shut down when its battery reached 0%, hopefully saving some battery life (although this might also be a myth), and had planned to do so with my Desire X as well, but after reading the mentioned reports (and this one, of course), I'd rather recharge the device even before it reaches 0%...
Maybe someone could shed some (technical) light on this... - the mentioned forum reports in the end did not offer other solutions than taking the device to a service center and have it repaired.

[Q] Startup trouble

Fellow windows users,
Im having a little bit trouble to fix my nokia lumia 920 white cover.
The phone broke down after a heavy storm at tomorrowland where the phone was touched by humidity.
Nokia care doesn't want to repair my phone because the water marker went of.
Before I handed my phone over to nokia, the only problem was that I couldn't make connection to my carrier.
(Proximus Belgium)
Sometimes I recieved a call but most of the times I had no connection.
After the 'repair' department sent my phone back without fixing it through the presence of water. (Couldn't be much because I only saw a little bit of corrosion on the sim tray. I removed that connection and tested the conductivity with my voltage meter.)
Now I have it back and it doesn't boot anymore.
I've successfully flashed the device with a new firmware from nokia. (It's the proximus red version)
But still I get the charging icon blinking when I try to power it up. The battery should be fully charged in the 12 hours it was connected with the original charger.
I've checked the battery and there is no damage or sign of water damage. The amp meter indicates that the battery is still functioning.
Is there a way to be check what the problem is? Because a blinking battery Icon doesn't explain much.
Maybe use a stronger adapter to "Boost charge with High amps' to rekick some life in the battery?
This nokia lumia cost me 430 euro's and only worked for 2 months so I'm really unhappy with nokia Care.
With friendly regards
Me
Kickstart
To help myself.
What would be the strongest charger that I could plug my cellphone in?
The battery has been dead for 4 weeks due to nokia.
So maybe a High amp kickstart should refill the battery to a level the wall socket could do the rest.

I think the only way to boost it is to disassemble from the phone and try to charge the battery directly, but all this requires technical & basic electronics skills.
I have similar water damaged 920, after full charge of the battery out side the phone.The phone drained completely even before got to windows phone slogan...this was because of electrical shortcuts in the main board due water corrosion
I think it best to sell the phone if you don't want to deal with ordering spare parts over ebay in order to repair it.
In most cases water damage cannot be repaired. You have to understand it gets in an under everything in the phone. The phone will always get cascading problems as time goes by. It may work for a while but will and I do mean will fail later.

I have basic elektronical skills so it wouldn't be that hard.
Now I'm letting the battery charge for 48hours sometimes that helps.
I'll post my findings within 2 days if I can kickstart this thing.

[Q] Battery "discharges" out of the blue

Hi,
My wife's been complaining about her sgs3, i9300a phone a lot lately, so I've been taking some time of to have a long hard look at it.
the phone in itself works quite well, it is somewhat guarded (she tends to drop it a lot but most of the time it's actually in it's case) and we've switched the screen once (well, not the screen, the top half of the phone to be exact)
the phone used to have a stock 4.1.3 (I think) samsung rom on it for the past year, it's been working well untill a couple of months ago I think and it does still function properly on light use
so what is the issue?
if you'll start a game, or anything that'll cause the phone to heat up - the screen would flicker a bit (not always) and the battery will suddenly report to be down to 0%, shutting down the device right after.
this sudden discharge is obviously not real, as the minute I connect it to a charger and boot up the phone it shows it's last charge before the phone was shut down - however the issue keeps on repeating itself over and over again.
If the phone is connected to a wall charger (or a pc via USB cable) this doesn't happen.
I've been trying to install a kitkat on the device (it have been working slowly so she needed an upgrade) yet the issue persists.
I've been reading around the Internet, some claim it's a faulty battery issue so I'm ordering one from eBay, however - I can't shake the feeling it might some other faulty hardware, perhaps a memory chip gone bad? as I can't see the connection between a bad battery and a flickering screen.
Truth to be told - I'm not a fan of android, or samsung, so I don't know much of the history of problems with it (if there is any) and I've been hoping that there is someone around here who might encountered (or heard) about my issue and would be able to shed some light for me.
thanks in advance!
Change the battery first, replacing the motherboard isn't worth it.

Yeah... I'm planning on stealing my boss S3's battery for some testing later on today if he'll ever decide to show up...
perhaps shouldn't have told him that beforehand
I did hope someone encountered and fixed/learned about this problem as the device has 2 years of history at least...
if it'll come to motherboard switching I'll just force the little lady to switch to a real phone such as an HTC, or maybe go to WP
It was the battery..
Perhaps I should've guessed it by the fact it was REALLY hard closing the case... but it was only after I saw a normal battery that I noticed the real difference.
so for future reference to whomever might meet the same behavior - my battery was about 1.5 the size of what it should be and was quite round,
better call those Samsung representatives and get a replacement before it explodes
Anyone has experience with those 4200Mhz batteries? worth the money or should I just get a genuine one (it cost about the same in here, like 4$ more), the reviews are quite mixed.
