bootloop after "wrong" flash odin, cannot enter recovery mode - Samsung Galaxy A21s Questions & Answers

Hi, I tried to flash the stock rom of my SM-A217F (XEF country code) and now it fails to boot, I cannot get into the recovery screen anymore, and there's a red message "fingerprint protection failed."
Any help would be appreciated!

As far as I know, that problem occurs because the bootloader is corrupted, and the only way I know to fix such problems is using a jtag or a similar device with so much caution and patience. If you can't get one, I'd suggest you take it to a technician you trust. Good luck.
PS: There are some videos on youtube on how to do this manually, but it's kind of difficult if you don't have experience with electronics.

The videos i've seen require removing the board and soldering some wires to the JTAG programmer, are these the videos you are talking about? Can you use a jtag without soldering? (sorry but i don't have any knowledge with this sttuff!)

Unfortunately, no. The only way jtags work is as you mentioned, you'd need to remove the board and weld the cables to the jtag. If this is too much effort (for me it is), I'd recommend you go to your local hardware repair shop. Good luck!

[Q] water damage!!

somebody pushed me into a pool with my clothes on a few weeks ago and I had my Samsung gs3 on me
I've tried drying it, took it apart, tried to dry the motherboard separately,... but nothing worked.
I got a new gs3 and the only thing I care about now is to retrive my photos if possible. The water damaged phone won't turn on and it won't connect to a computer. To make sure that the problem is the motherboard not the screen I've switched the motherboards to see if it works or connects to computer but it won't.
Does anybody know how I might be able to retrive my photos?
I think the solution might be to take the phone's internal memory out and maybe install it on a working board and recover photos from there but I dunno if that thought is doable??
Anybody knows of a repair shop that could do that for me?
Any suggestions?
Thanks in advance
Yeah ..i saw someone do that once ...in an episode of CSI !!
I know its not that helpful but hey ..at least im trying to cheer you up .
Good luck with your project and ask your dumbass friend to buy you another s3

I will, but the problem is I already took it to a repair shop and they couldn't help me and there are not a lot of pros in this field in the city I'm leaving
I thought maybe somebody could refer me to a pro and I ask them or mail the phone/motherboard to them
Sorry to hear about that, things happen though.
Did some research for you and found this: http://digital-photography-school.com/recover-images-from-a-damaged-sd-card
but I am not entirely sure it will work. If anything, you would take the phone back to Samsung to have the data removed
unless you have lost your warranty.
Good luck anyway.
It's probably possible to recover the data from the integrated ssd drive through complex and very specialized tools aswell as lots of work.
This would involve desoldering the chip from the motherboard and hope it's not defective due to your attempts to use the device.

In future, open a dropbox account and install dropbox on your phone.
This way, all your photos will upload automaticly to your dropbox account without any manipulation.
Good luck Bro !
thanks for the search
but unfortunately I wan't using sd card before so the pics are on the phone's memory
I do still have the warranty and I called Samsung but they would just repair it and wipe all the data off the phone they won't recover it for me

[Q] Lost volume in right channel

Hi All
I tried to find the answer, in vain.
For the last few weeks the volume of the right channel has nearly disappeared. I have 95% on the left and 5% on the right.
I use the original software in it.
I was looking for a balance button but can't see any.
The warranty run out two weeks ago.
Any thing I could do to restore its volume.
I tried different headphones, no changes.
Thanks
TA
Replace jack; fairly sure there's a detailed run through (with pics/parts needed) in the service manuals for the phone which have been posted here in the past (do an XDA or Google search). Or pay a local mobile repair shop to do it if you're not confident enough.

Is it an expensive task to do? I don't see myself doing it nor have the tools for the job.
Don't know/don't know exactly what parts are required (but remember seeing the run through in the manuals). It's fairly obvious it's a hardware issue, and as it's happening with headphone/headset, logic says you replace the jack first. Obviously if you're paying someone else to do that, it becomes expensive due to the cost of labour.

So, after some extra search, I have discovered that there is something broken with Android 4.1.2 audio.
I have installed Poweramp and got the some balance back. So it is a software problem.
Where to go from there?

How to extract photos from hard bricked XPERIA P ?

Hi..I had the very same problem that is mentioned in this thread, and it seems like that the phone is dead for good:
http://forum.xda-developers.com/showthread.php?t=2383875
My only question is, how can I extract my photos & vedios from the internal memory? Of course I understand that this isn't about USB cables and stuff, I know that I'll probably have to dissemble my phone, and I'm willing to do that, I just need to know what to do exactly? Thanks in advance for every body..

I believe there are devices that can read the memory, find a lab that has one compatible with your phone.
Have you tried all tricks, like rubber band?

bricked? Help understanding s1tool output (Hard bricked?)

Hello, I have problems with a u20i x10 mini pro.
I tried resetting with pccompanion, as well as flashing stock firmware (no error in flashtool log), but phone enters a sort of bootloop, without even arriving to SE logo. Only, display gets light, but nothing is displayed. Phone sometimes vibrates, when power button is pressed. No led light seen.

It's not hardbricked, in a hardbrick you don't get any responses from the phone. I think maybe your flex is broken, that's the ribbon cable that connects the screen to the rest of the phone. Other than that, i wouldn't know why it's not working properly.

Thanks mate, then I'm opening it tomorrow (I just don't have any tools with me right now).
Just another couple of questions before opening:
1) I would have expected the phone to turn on and without the display (and hence, be available via usb), instead of continuosly rebooting. Am I wrong?
2) does the ribbon cable brake, or sometimes just detach from the board?
thanks again (for the info as well as for the prompt answer)

Well... as for nr.1, you do get a response from your phone in S1Tool, so that is ok, and if it was booted you would have to turn on usb-connection from the status-bar in order for it to connect as mass storage The screen not working prevents you from doing that. On the other hand, the drivers for the screen and the digitizer may give a fatal sort of error because they can't connect, resulting in the kernel stopping the boot. Both are sort of guesses on my part but may explain your problem.
As for nr. 2, It usually breaks It's the most common hardware failure on the U20.

I see... and, please correct me if I am wrong, a broken flex cable could explain the led off while charging and while flashing, right? but, isn't also the "back" key connected through the flex, in the end? just for my information, I don't mean to test your knowledge
another couple of questions:
3) do I need to disassmble both the lower (the one of the battery) and the upper (the "display" one ) parts, to check the flex, or can I just concentrate on the upper one?
4) I suppose there is no way to repair the flex, if is is broken....
thanks for the valuable information!

Yes, it would mean the led wouldn't get any power, but the flex is a parallel cable, with lots of wires connecting various parts, they may not all be broken, so you might still be able to use the keys, or with some people, half the screen sometimes.
As for the disassembly, there are tutorials and videos you can follow, just search them on google. And a new flex-cable is quite inexpensive, a few quid should buy you one.

is the flex glued onto the metal plate? Do I have to destroy the old one? (and that would explain why all the video guides end without "disassembling" the flex do I need any special tool to attach the new one (assuming that I am really going to do the job )?

I received the new ribbon and put it in operation
Actually, I need a couple of further suggestions:

2) How do I solve the sim-lock?

I don't know if you need to glue it, maybe you could even use some tape to stick it, roughly in the same place where the old one was attached, if that was attached at all.
Secondly: What about the sim-lock? Do you mean it's locked to one particular provider, without accepting other sim-cards? Or do you mean the code you have to fill in before the phone is booted up?

Right... that is a sim-lock... either use a sim-card from the provider the phone is locked to, or ask that provider for an emma/imei code in order to unlock it. This is usually free after the initial contract period. The only other way is to use a paid service to unlock it.

It can be done over the internet, but everyone who offers that service will demand money for it. The only really free way ( and the safest way if you want to unlock the bootloader and play with custom kernels and roms ) is the code from the provider. There isn't some sort of logo or sticker inside that will identify the provider? Come to think of it, there should be a model-sticker inside with an SI number on it in the format of: 1238-2562 (that's my number, SE original Customised UK black ) One of those two numbers is usually a provider-code you can look up on the internet. I wish you good luck
(And flohmarkt is german for flee-market (usually american english), or car-bootsale (more commonly used in the UK)

I have no idea if that is legal, but since the Austrian government isn't reprimanding them I guess they are within the legal limits of doing so. The 'normal' thing to do though, is to do it for free after the initial contract period is over, since the phone is paid off by then, and there's really no need to keep it tied to your own network.
I can somewhat understand the difference between the receipt and non-receipt prices, they don't want to make it worth while for stolen phones to be used any longer. (Not that i'm saying your phone is stolen, but they can't know without the receipt).
I suggested doing it through them because it is usually free, but since you'll have to pay for it, You could try something like Omnius. They are a paid service, but they should be cheaper than the provider in this case.

Not to the phone-makers, a nice present to themselves, making money of a phone that's already paid for, and the only thing they have to do in return is e-mail a code they've got stored in a database.
They are hoping you'll go for a new phone (and contract) which would make a nice present for them AND a phone-maker It's win-win for them, apart from the fact that you're now pissed off and will never go for them as a provider in your life

very bad news from my small mobile phone
I had always had the feeling that I assemblied quite fast and not really well, so I decided to open it again and fix the ribbon with some glue... long story short, it does not work at all! No reaction at power on button, no reaction on linux (lsusb used to show a device, when the ribbon was broken), no reaction from s1tool... I fear I really broke something, this time... do you still have some suggestion for this case of "no response at all"? I actually don't think I ruined the ribbon with the glue (which was my first guess), but I don't know what to consider now...

No chance. If you have to ask, you won't be repairing it on your own. Why ? If you had the necessary knowledge/skills, you'd be resourceful enough to have already found out the extra info you might need.
Take it to someone who knows what they're doing, or if you fancy rendering the phone permanently unusable, search for the service manuals; they've been posted here before & a Google search should turn them up.

How do you honestly expect anyone here to diagnose a phone that's been runover by a car without having the phone in front of them ? Be prepared to be very disappointed. You also just proved my suggestion that you're not capable of fixing it with that post of yours; save yourself time/grief & take it to someone skilled in repairing phones. Or sit here in this thread expecting the impossible for days/weeks/whatever *shrugs*
