I managed to hard brick my phone, any way on fixing it? - Samsung Galaxy M20 Questions & Answers

I just made this account, so I could not post it on the custom roms and recovery section.
So I managed to hard brick my phone, bootloader doesn't open, at all, I cant get into recovery, no shortcuts work, nothing. Before, I had rooted my device and had OEM unlocking plus USB debugging, so is there a slight chance I could fix it?
(I can't replace the motherboard, nor can I buy a new device, not even able to go to a service center or local service)

Factory Reset, start configuring language, dont connect any WIFI or DATA and Next button after this the screen show Configuring Phone, press volume up + volume down - home button and button back, and Woola bypass the stupid activation
This is the method
Thanks guys, I managed to skip this step. I founded tutorial on youtube, but phone must be connected to WiFI, otherwise there is no skip option only back to connect.
I have another problem, now it says that SIM card is invalid. I cannot connect to mobile network. It seems it is SIM locked, but I used current SIM with this phone and had no problems. Do you know guys is there some possible way to unlock again this phone without root? Again, I cannot contact Sprint because I'm not their user.

you might be able to try some trusted 3rd party unlckers no way to downgrade either or brick will result to try inter nat rom so thats not an option either and problem with some 3rd party unlock companys is sprint still has apns greyed out so not able to mod them some have reported ok but basicly now its a monetary risk and in my opinion the device isnt really worth investing any cash into except for the camera no root methods are available beyond zv6 firmware no downgrade possible

you might look for sevice menu ## codes look for a setting that says itson and disable it may need msl code n wich is still obtainable throught sprint its hard work but i have done it many times
mayers unlock method sometimes requires manual diable of itson to get rid of invalid sim card notification
no root needed
I bringed my device in local service shop to unlock, but they returned phone more damaged. Device can't turn on and when I connect charger there is no charging indicator, nothing. When I connect phone to computer it is recognized as "Qualcomm HS-USB QDLoader 9008". Is there any solution to unbrick this phone? Any answer would help. Thanks!

I would take it back to said shop and raise hell they damaged it they need to replace it. What firmware were u on. It dont really matter. The firehose.bin for qfil to reflash fone doesnt work for g4. Unless someone has made a new one but i havent seen one yet. You might try lgs waranty. Claim to have bootlooped. Or something like that

I dont know. If i tear up someones phone im working on. Its kinda my obligation to fix or replace it. I do unlock what phones i can. Repair. Root and modify. I wo far have a perfect track record with customer devices. But. If it ever came about i brick one. Like said. I kinda feel obligated. Or is that not a thing but a courtousy?

Totally agree with you. But people are different.
I, too, have long ago discovered my telephone cemetery)

(HTC DESIRE 500 HTC__M27) What if you can not enable USB Debugging at all?

Okay,
I have just created this account to ask this even though being aware that the phone is outdated. What is the solution for a phone which can be reached (connected) via USB without a problem, variables can be read and apply fastboot commands.
After reading countless topics, trying many softwares, trying many different original RUUs (HTC__M27 region especially considered) (since android is not booting, impossible to enable usb debugging and of course not possible to try custom roms etc. At this point s-off is not possible either) watching many many videos and such i started to think the only solution to revive this phone might be nothing but replacing the mainboard on it.
I remove the battery for sometime and when i try to switch it on normally, it vibrates 7 times (very common problem for most cases) and stuck with HTC logo forever.
If i apply the volume down, power up combo, phone can enter into Hboot, Bootloader, Fastboot, Recovery, Simlock, Barcode, Factory Reset options. When i try Recovery, Factory Reset nothing happens always stuck on HTC logo forever.
Even with the original ROM for my region which is Turkey HTC__M27 i get Error 131 Customer ID error.
I want to ask the community is there any solution for this kind of a situation?
Please kindly inform if you have time.
Thanks.
Answer to my own problem.
Simply phone is dead because 99% the emmc is either damaged or needs to be reprogrammed.
If your phone is S-ON and you are trying to S-OFF it and if your phone is unable to boot into android os you can not s-off it. All S-OFF methods needs "USB debugging function enabled". Since no os to reach and modify settings, you can consider your phone is a dead one and not going to rise at all.

Need help unlocking the phone (HCU Client etc)

Hey there.
So the other day I bought a broken Huawei P9 for really cheap. I repaired it and now that it boots, it is locked by the previous owner (by 'locked' I mean it has a pin code/fingerprint). They guy I bought it from claims that he found it in a store. So no one knows the pin code to unlock it.
I tried to wipe everything by accessing the recovery. In the recovery, there is the option to download and check the recovery but when I select it, I get a fail message. Bootloader is locked I believe. So what can I do?
I downloaded HCU-Client but the phone wont be detected by the software. I installed HiSuite for the drivers. Is there anything I can do to wipe the phone or at least make HCU client recognise it?
Thanks in advance

Enable ADB or Unlock bootloader with dead LCD

I have a nexus 6 device, recently the phone dropped and the digitilizer stopped working, but as i was searching for ways to backup data the screen went completely blank as well, the data is extremely important.
The phone is working perfectly debugging is off and it has a pin lock, i cant get data off by connecting a USB as it requires to unlock the device which i cant.
Serching the forums some people have mentioned they used WUG's toolkit to unlock bootloader without losing data! is it possible or am i missing something?
example: https://forum.xda-developers.com/nexus-6/help/enable-usb-debugging-recovery-t3434971
What i want:
1. Enable adb somehow
2. The only option i see in to flash custom recovery but that requires unlocking bootloader, i cant delete my data.
I also can't find a replacement LCD for this phone where i live suppliers don't ship here

You can't do anything without "USB debugging" so you have to replace the screen.

Unbrick Redmi 8

My phone suddenly get stucked into Redmi boot logo, cannot access system recovery but can access fastboot menu.
The problem is I hadn't enabled OEM unlock and developer options before. All the methods that I found so far requires bootloader unlock for that I also don't have MI account . What might be my next move? Thank you.
its hard to say what we can|t do with a still locked bootloader. if going to an authorized service center is out of reach, all we can do is try i guess. id still suggest going there if you can easily access your google account.
there are a few threads that say we can flash a still locked bl, but im not so sure.

Xiaomi Firmware Updater

With EDL mode? I'm in a similar situation, a friend's mother forced a shutdown during a firmware update and destroyed the system that way. Of course the bootloader is blocked. I find it extremely stupid of Xiaomi to rely on a working system to give you the chance to unlock the bootoader but I guess that's how you sell some extra phones.
So far I've taken out the rear cover and the plastic that goes on top of the motherboard, unplugged the battery and with an arduino cable and some fiddeling shorted the "boot" pins while connecting the USB cable. Seems to be working given that MiFlash has changed the locked bootloader error for "indice fuera de limites" or in English "index out of limits error". I guess I don't have the right ROM so I'm downloading another one, but I'm struggilng to find the correct original fastboot ROM. The first one I've downloaded from Mi Community, the second one is from xiaomifirmwareupdater, but is gonna take forever to download. And I mean... F-O-R-E-V-E-R

gl with that, as only authorized people can properly flash from there. while i havent used EDL, there are some trusty people who can help us out (ive seen it in tg groups)
a site did say maybe using another version can help, who knows it might do the trick
