Yesterday i tried to unlock bootloader with adb tools i was suprised because the device was unbricked of caurse without all my files . Everything was good so i tried installing custom recovery and root it ,all went smooth no bricking or anything, until today at work it started freezing and only restart was helping .About third time it did the same thing as before even my backup file went missing only thing i got is bootloader and twrp even connecting it to pc in recovery mode shows no folders no files no system and adb cant see my device . Please help sory for my bad english and long post i just wanted to sum up the whole problem

HELP - Phone cannot be factory reset... To cry or laugh?

Hello everyone!
This is my first post here, and I have a problem with my phone.
It is Highscreen Boost II (russian one, you didn't maybe even heard about it). Google for it...
The main problem is that the phone started to act strange one day. Example: I unlock the phone, start opening my apps (Fb, Insta, Viber...) and after a few minutes it just restarts by them self. I also tried to turn OFF the Internet connection, but all the same thing.
The phone is rooted, and it have CWM recovery. And here starts the funny part. XD
When I go to CWM, i go to factory reset, it all done right, it says "successful" on the, but what is the strange part, that it just takes like 5 sec. to do the "reset". When I press reboot system, it reboots the phone, but nothing even changes XD.
I also tried, flashing new ROM, it says that is all done, but when I restart the phone, it just came back on the previous state that it was before. The other funny thing is that, the phone keeps go back, on the same date (~20. February 2017). I fix it manually in the Date and Time settings. I also tried in CWM, to go to Mounts and Storage, and doin' from there format of the SYSTEM, and than flash the ROM, it flash it for 10 sec. Reboot and all the same stuff. I even tried Mount /System and than Format it, i tried to format everything, but without success. It just says the CWM that is done, and nothing else...
Than, i tried to flash the Stock Recovery (it can be flashed from the CWM), it says that it's flashed, than when i try to reboot the phone in the Recovery mod, again it comes back with the CWM, so in fact, nothing has changed in the end. I also connected the phone with the ADB connected to the PC, entered in Fastboot mod, Booted in the STOCK RECOVERY (live boot - to say...), using the commands in the terminal, it successfully boot up the stock recovery, than i tried to do the factory, cash and all usually necessary before flashing the Stock ROM, after that, i flashed the ROM (from the ZIP file, SD card...), again, it was very short time, saying that it was successfully installed, restarted the phone, and imagine it all works good
-\ Nah', just kidding, it is the same thing again, all the same, not even changed the Recovery, the ROM, nothing... I also tried flashing the Custom/Stock ROM thru the commands on the PC, it says DONE on the end, and all the same, nothing...
After all that, i decided to restore the phone with other ROM (to say) in the way to go to the DFU mod (pressing + and - and Power button together), so i enter the phone in Download mod (to say). In that way, once (2 years ago) i recovered my phone from Hard Brick, since i deleted the partitions and all that stuff....
Than, i decided to flash the ROM from the DFU tool (Innos Upgrade Tool) - from here i was following the instructions, and doing all like before. It is connected in the device manager, and detected as DFU android phone (something like that), as it should be. When i try to format the partitions, it just crashes, or when i try to flash the ROM, it went to 100%, and doin' nothin' I even tried to reboot, and all, all over the same thing...
I want to add, that, i remember that on that date ~20. February 2017 When it always return to that date/time over and over again, that on that day, i re-flashed the ROM, because my system started to crash from itself... So by flashing the ROM from CWM only, it works fine, and didn't lost any app, i mean didn't needed to install all apps that i am using...
*The phone is running fine if i don't use it non-stop, i mean if i start to go in my settings, and click too many times, it will just reboot and go back on that date/time state... I am using it only for calling and sending some SMS. Nothing else...
*My 70% of the apps, we're on the SD card moved, trough the Link2SD app (root), so i cannot uninstall the apps that are here, neither i put the SD card IN.... This doesn't matter. But another thing is that, if i for an example took a Photo, add contact in the phone book, send SMS, call someone, after restarting the phone that data/info/sms/photo is not there... It acts like it is in the cash memory, something like that... It just all looses and starts over again, from the same date, and time.
My opinion is that the phone, somehow... that the "NAND" memory chip is death (just an example)... Something like the BIOS CMOS battery on the PC's, that is dead, and cannot keep the changes, after rebooting the phone, so it goes back on that time when it was last time in "good condition".
I really don't need the phone anymore, but it would be nice for an backup option to have it fully functional.
I want to hear your opinions, did you ever met a problem like this before? If you did, what did you did/fixed it?
For me this is kinda funny, because i never had/saw a problem like this before. So i don't know should i cry or laugh around... XD
Thanks.

Help needed to install the stock rom back

Hi,
First I want to say that although I am not a total newbie, I can be considered as a newbie. I have windows 7 32 bit. I am starting from the beginning.
Until about 1.5 years ago, I was used to connect my phone to Kies and do a "firmware upgrade and initialisation" after feeling that it is time to do so in order to speed up the phone back. Does it speed up the phone back? I'm not sure, but as a guy that still formats his pc from time to time maybe it's a habit.
But about 1.5 years ago when Kies told me that my phone is not supported any more I couldn't do that. Then I made some search and found out cm.
I first installed cwm 6.0.4.3 to my phone by heimdall 1.4.0 then installed cm 10.2.0 and gapps-jb-20130813. I thought it would be good and my phone would be faster since I wouldn't have the unnecessary att apps. It also supported Turkish whereas the stock only supports English and Spanish.
I actually liked it at first except for some parts. Then a few months later the phone switched its language to English itself and started to behave abnormally, so I switched back to latest att stock rom by using odin3-v1.85.
Then about 3 months ago my phone got some water inside when I was under the rain with my phone in my pocket and my pocket not being sealed enough. The phone at first said please insert sim card when it was actually inserted, then I noticed it got wet. I immediately turned it off and removed the battery. Then opened it up and let it dry for a few days.
The phone got back to normal except for a single issue. When I charge the battery the screen behaves abnormally. The abnormality increases with time during the charging, I thought it is related with the phone getting warmer during charging. After the phone turns the screen off after timeout, It does not always turn it on after I press the power button. It starts at first by turning on after a few trials up to not being able to turn on during the charging process. When I unplug the charging cable, I can turn the screen on after a few trials. The phone gets back to nearly normal after 10-15 minutes. Although the screen does not turn on it still responds, for example I can answer a call. And sometimes the screen turns on with being upside down and flickering but responding as if its not upside down.
I hope I could describe the problem well. So this may be a hardware or hopefully a software problem. So I decided to first go back to factory settings. The problem with the screen continued. Then I installed the stock rom by odin. The problem continued but I noticed that the two applications I installed after resetting to factory settings remained in the phone. odin either not installs the rom or installs it by copying files, not formatting the system partition. I thought maybe formatting and reinstalling stock would solve the problem with the screen.
I made some research and noticed that I could actually increase the system partition, which is awesome since I always encounter filled memory problem when I try to install an app so I uninstall some apps to install the new ones. If I manage to repartition the system drive, it also has to format it.
Then I installed the stock rom using the pit file someone uploaded (6GB system partition), I did it but got an error from cwm upon first boot saying something like "unable to mount F", when I ignored the error the phone seemed to turn on but got stuck with att sign. When I pull the battery and turn it back on the phone got stuck at the same place without an error from cwm. Then I installed the stock rom with the original pit file, now the phone turns on but I still have previous apps. I repeated thes a few times (6gb pit file, original pit file) but nothing changed.
Then cm came to my mind, it would format the system drive. I repeated the same procedure I did 1.5 years ago. The phone turned on. I noticed that the internal sd drive had the previous folders,so I wiped the sd drive with cm. Everything was fine but the problem with the screen continued which stated that the it was a hardware problem. There was no reason to stay with cm so I installed the stock rom.
The phone asked a password from me since it had encrypted folders ???. I didn't provide a password, I think it did not recognise the sd drive wiped by cm.
I couldn't install cwm 6.0.4.3 with heimdall, it gave an error at the end. I decided to install a recovery with odin so I installed twrp 2.8.7.0.
I installed cm with 6gb pit, with original pit, installed stock rom with 6gb pit, with original pit with random order and how many times I don't remember that I brought the phone to a state that it won't boot. It turned on with odin mode though. Even the twrp did not recognise the drives. So I wiped all with ext4 format.
Now I have cm with 6 gb system but I want to go back to stock rom. cm drains up my battery. I also noticed that I really got used to the stock rom. I would appreciate it if I have 6 gb system like now. But if I have to reduce it back to 2 gb I don't care.
Can someone please help me?
Sorry for the long post, I wanted to state the problem as good as possible.

Not getting even a single reply probably means I am facing a really extraordinary problem.
I'll try to reformat the partitions. Maybe the OS thinks the unrecognised partition as encrypted. I previously made them both FAT.
Can someone please tell me what should be the filesystems of the system and the internal sd? Are they the same or different?

I could be wrong but Ext4 is the most common filesystem so try that

Stock rom keeps corrupting, advice please.

Sorry if its been asked, i tried a search but couldnt match my problem.
I bought a used samsung s6 for my son, it seemed fine when we checked it.
But its got an odd bug where if it restarts it gets stuck on boot up.
I've used smart switch to reinstall the offical samsung stock rom
The re-install all his apps.
The phone works fine and re-boots fine.
But after a few days, if restarted it wont boot and just gets stuck on the boot loadung screen. None of the special boot options helps, clearing cache or reset.
The only fix is to use smart switch to do a complete wipe and reinstall official software.It has never had Knox tripped, and the guy didnt seem to be the type to run a custom rom.
It getting to be a pain as he cant turn his phone off and if his battery runs down gis ogone will become useless until i re-set it and wipe all his data and settings. Which I have to do on an almost weekly basis
I have a few questions...
Is it a hardware issue? (It the stock rom on a phone thats never been modded afaik)
anybody know whats causing this to bomb in stock firmware?
Any idea how to fix it?
Would a custom rom fix it?

I had this problem with my brand new S6 when I first got it. Yes, random reboots were occurring every now and then, which I could live with. Then one day it just got stuck at the boot logo and didn't boot no matter how many times I re-flashed stock firmware with Odin. Turns out it was an issue with the Main Board inside the phone. Once I got it repaired it's been fine ever since.

The reparations involved replacing the entire Main Board with a new one.

bootloop 4 blink red light every time I restart device

Hi,
I' sorry if I'm posting this in the wrong section or duplicate. I searched around and found something similar but les detailed or with rooted configurations.
I have this issue, when I reboot the device, it stucks in bootloop. This happen:
-power on 1 vibration
-sony logo
-android logo
-white screen with animated waves
-stuck animation
-4 times red led blinks then reboot
usually I use this energy saving apps: Greenify, Brevent, ForceDoze
Nova Launcher, not rooted, stock ROM Nougat 7.1 (from Xperia Companion)
and usually I don't stop anything of system apps
other apps are regular apps
The first time it happened I had repaired with Xperia Companion,two reboots, none issues.
Every time the issues happen the system seems buggy or something, like if i press back button it shows me stock launcher instead of Nova, or Sim Network is unresponsive, or some other little things are not so fluid like usually are or are not expected.
Flash stock ROM with flashtool doesn't resolve the issue (stays in bootloop), only full repair with Xperia Companion or a flash with complete wipe
can't execute ADB or Fastboot, in the flash mode (fixed blue led)
my question is: there's a solution to this?My mobo is bricked?there's something I can do without software repair, or reflash it?
around i found someone that says "SE2Tool JTAG flash" resolve this issue, but what I now this tool is used by rapair shops
anyone can help me?

Hi, I have the same problem. I tried to flash stock rom just like you did but without wiping cache and data because I got important files in storage. So I didn't even try to perform a full repair with Xperia Companion since it wipes everything in storage. Did you find the solution? Please share with me your experiences. Thanks.

Hi, the last time I've reflashed stock rom wiping only cache, data remain intact. Still working since then.

Just did that. Flashed the stock rom while only wiping cache with the Flashtool. Still no luck. Thanks anyway. Do you have any other suggestion?

first of all, it sound silly, a scheduled time to time incremental backup.
it's more easy to avoid-mitigate this boot loop issue rooting and install a bootloader like twrp. there are a lot of guides here that explain how to.
with recovery you can choose to backup data partitions if stuck on bootloop, on stock you can't do anything.
in your case if the reflash did not work you must do a repair through companion software, loosing all your data. or pay a service shop to recover it, but o don't know if its worth it
