Hi all. This is by way of advice, information and a question.
I have a 7105 on contract and it got dropped. It was rooted but running stock 7.1.1 and was fine for months and months before I cracked its screen. My contract covers accidental damage so I got a new one. Thanks to the excellent guidance with various Android phones over the years from this forum I've happily rooted, hacked and generally mucked about with loads of HD2s and my 7105 and never had a problem.
Until now
When the new phone came I just dived right in. Rooted ok. Started to use Titanium backup to restore apps. All going well until I got to Flight sim game. In the middle of the restore, the phone rebooted and when it came back up it was in factory mode. You lot being by far the best source of advice I hunted this down in the forums and found a nice solution to fix it by modifying the keymgr and factorymode text files in the FactoryApp folder in efs. My problem was that I couldn't alter factorymode. It was in fact corrupt along with a number of other files. I'm sure you can imagine the panic! To cut a long story short. A day of intense hacking got me nowhere because I panicked and started flashing this and flashing that all to no avail.
After a sleepless night I turned to my own fledgling knowledge of Linux and using ADB I connected to the phone whilst it was in restore mode and used e2fsck to repair the efs partition. Once repaired I was out of factory mode! But the problems didn't end there.
I then ended up with what I would historically call video ram errors. Random crap appearing on the display. Coloured flashing lines across the screen etc. I couldn't fix this so I had to do the best I could to restore the machine to normal with TriangleAway. Unroot and generally get it back to factory condition before returning it as a faulty replacement.
So Advice: always back up your EFS folder. Even if you aren't flashing new roms! If you just root it then anything can happen!
Information: If your EFS folder is corrupt (this is from memory so forgive me if I'm not 100% right. Should be close enough though) start your phone in restore mode, connect with ADB, set permissions to root via su and then run e2fsck on the efs device. It's in /dev/block/something. if anyone really needs this I can probably dig it out of my current working phone
When using e2fsck there are two parameters you need. The first does the repair. the second important one is to force a repair even though the superBlock says all is well. For me this fixed factorymode file and several others.
My question is this: Could I have just been unlucky and genuinely had faulty hardware? The lines on screen and peculiar display behaviour in all screens from the bootup display right through to wallpaper in the shell were clearly indicative of video ram from experience but could a file in the EFS folder determine video subsystem parameters perhaps? So a corrupted file in the EFS file system was setting up the video hardware incorrectly?
Would be really interested to get some views on this
all the best to you out there and - as always - thanks for all the help and advice over the years.
Hello....I bricked my I927 when I accidently formatted my efs partition when using EFS professional .....my phone boots in download mode.....but only boots till samsung logo screen.....I tried various things like installing stock GB and ICS through odin and installing custom firmware but phone boots onle till samsung logo and then lights up with sone stange colored thin lines and screen goes off.....In TRWP I get a "unable to mount preload" error whenever I try to install somethiing.....I suspect that the EFS partiton is corrupted and needs to be repartioned....I had backupped the efs folder when my phone was working before.....its in a tar format.....I read somwhere that someone made a recovery.zip out of his backedup EFS.IMG and flashed it with CWM solved his problems which were exactly similar to mine.....can somebody on the forum make a recovery.zip for I927 with update binary and script so that I can add the backedup EFS image to it and flash it with CWM? Please.....this would also help many others who are facing similar issues.....and also what do I do regarding the "unable to mount preload" error? I need to repartition and tried to install hemdall.....but get the common .dll error even after following all the instructions and installing C++ 2010.....
Hi, k one thing after the other.
Do you have repartitioned anything?
Do you have adb in place and does adb works when in TWRP?
The easiest thing would be to connect by adb then mount /efs and then restore the efs backup. The good is that you will have a good chance to recover your device. Maybe you need to reformat /efs but that depends.
Which timezone do you live? Maybe a Teamviewer session would be helpful?
.
Thank you for your reply sir...
THANKS FOR THE REPLY SIR....YES I WAS ABLE TO GO INTO CWM RECOVERY AND CONNECT THE PHONE WITH MINIMAL ADB FASTBOOT.....AND AFTER SPENDING ALMOST 2 DAYS CONTINUOUSLY TRYING TO FIND THE PROBLEM USING GOOGLE, I TRIED DIFFERENT COMMANDS ON ADB TO GET EFS BACK OJ THE PHONE....BUT WITH NO SUCCESS...... MY EFS BACKUP IS IN TAR FORMAT......IT WAS MADE USING GALAXYSIMUNLOCK BY SPOCKY.....I LATER TYPED IN 'ADB MESG'.....OR SOMETHING SIMILAR TO THAT COMMAND, AND FOUND OUT THAT ALL THE PARTITIONS ON mmcblk0 were mangled up with strange letters.....for eg, p1, p2, p3 and so on had strange characters written next to them.....SO I TRIED TO RE-PARTITION THE WHOLE THING WITH SDPARTED......AND IT RE-PARTIONED THE SYSTEM (AROUND 7000MB).....MMCBLK01 (AROUND 500MB).....AND ANOTHER THING I CANT REMEMBER NOW.....BUT WHEN IT FINISHED THE JOB, IT GAVE ME A mmcblk02 ERROR.....AND WHEN WHEN I CHECKED MY PHONE ON CWM SCREEN, IT GAVE ME A LIST OF CACHE ERRORS.....AND WHEN I SWITCHED OFF THE PHONE AFTER THAT IT REFUSED TO POWER ON.....IT WAS NOT EVEN GOING INTO DOWNLOAD OR RECOVERY MODE.....BATTERY HAD ENOUGH POWER....SO ITS NOT BATTERY FAULT......I SUPPOSE THAT SINCE THE PARTITIONS WERE FORMATTED THE PHONE BECAME COMPLETELY DEAD......CAN YOU TELL ME IF THERE IS ANY WAY WHERE I COULD GET THE COMPUTER TO RECOGNIZE MY PHONE USING A 'DEAD PHONE USB FLASH' OR SOMETHING.....AND THEN FLASH A BLANK BOOTLOADER AND THEN WRITE CWM?
I LIVE IN INDIA SIR.....+5.30 GMT.....I DO NOT KNOW ANYTHING ABOUT TEAMVIEWER.....IS IT AN ANDROID APP? CAN YOU EXPLAIN MORE IN DETAIL SIR?
PLEASE LET ME KNOW HOW TO GET THE COMPUTER TO RECOGNIZE THE PHONE AGAIN......
Well.. that sounds not that good...
Teamviewer (www.teamviewer.com) is an easy to use and free remote control software for your PC (it runs on both Linux and Windows). We could do a remote control session if you like. I can try to help but cannot promise anything.
I live in Germany: GMT +1. Send me a PM if you want to give that a try. Next Monday. Tuesday or Thursday would be possible on my site. At least for getting a short overview.
.
Thank you sir,
Thanks for the reply Sir.....I believe using teamviewer requires a internet connection with good amount of data.....I have an extremely slow 2G internet connection here in India.....I searched google to find some solution for the bricked I927......and came across many posts where people have used the 'unbrick.img' which was specifically made for their samsung phone models on their SD cards to resurrect their dead phones.....The method involves creating a 'unbrick.img' with emmc files extracted from another working I927 and then writing the image on an external SD card with some linux commands or win2image software and then inserting the SD card into the dead phone and switch it on by which it goes to download mode.....once in download mode I can flash CWM or TWRP and also flash stock firmware through odin and recover the phone.....Since your a developer who is well versed in things pertaining to this, can you make a unbrick.img file for the I927 and upload it here Sir? It will be very helpful for others also on the samsung glide subforum, as there is no proper 'hard unbrick' thread for the glide on xda......Ill be very grateful and thankful to you for all your help Sir.....

Ok I have made one. It want to say it was VERY hard to find the correct instructions to do so and therefore I'm absolutely not sure if that will work for you!
Test it if you like but again: I have no idea if that would damage anything more than it is now!
See --> http://forum.xda-developers.com/cap...od-unbrick-debrick-hard-bricked-i927-t3285505
If it worked for you (would be like a miracle) then please report back!
If it does NOT work for you please report back, too!
thanks
xdajog

UPDATE:
Besides the link I posted --> Could you please also try the following:
1) Power on your device and directly after that:
2) Press and hold down Vol Up + Vol Down (both the same time)
3) You should see a warning message like the attached one which is the APX mode
4) you need to release the vol buttons immediately after you see the APX mode otherwise it will continue to the non working download mode.
Does teamviewer require internet connection with a lot of data?

Uhm do you have read my above post??
.
1927 wouldn't boot.....Help.
Ohhhh Thank you.....thank you.....thank you for your kind reply Sir.....how good of you to take all your precious time to help me.....I greatly appreciate all your hard work Sir.....wonderful...*.I wanted to download your img file to try it out and when I read the reply of brother Bubor, that the I927 woudnt boot from the SD card when the bootloader is bricked, I was very disappointed. Like I said before, I have a very very slow internet connection with very less data left....and according to brother bubor's reply I doubt this will work....It looked like he was sure that it wont work....I tried to get into APX mode as the link that brother bubor posted had mentioned, but no luck, as the phone is not going into APX mode.....I remember that when I was trying to get to the APX mode the first time, the computer flashed a notification that the APX driver was not successfully installed.....but after that I tried the method more than a dozen times, but the computer was not recognizing the phone to go into APX mode.....Does the phone go into APX mode when the full internal phone system is formatted? I tried your second method on trying to get to APX mode, but nothing happens.....the computer is not recognizing the phone.....The battery had about 30% power in it when the phone got bricked 2 weeks ago.....Dont know if the battery drained all these days of not using the phone.....And even if I get to the APX mode, I have no idea how to proceed from there to repartition the internal phone system and get back download mode.....In the link that brother bubor posted the person who made the thread has made some files to be used when one gets into APX mode.....The PIT and emmc files which are necessary for repartitioning the system and getting the bootloader work are found in that zip file.....But that zip file is for the I9103 Galaxy R.....there isnt something like that available for the I927 yet.....And is brother bubor sure that the unbrick.img file wont work on the I927?
Give it a try with my unbrick image.
we all don't know.

Hi @alvcross: any update on this?
have you tried the SD card unbrick?
You said you cannot open the APX mode but what happens when you press the buttons for accessing the APX mode?
Try it even if you see a blank screen and then connect your Cappy with USB to your computer --> you should get a message about a missing driver or similar.
If that works I tell you how to proceed.

Ok so you may try to install the special apx drivers now. Unfortunately I'm on vacation right now so I cannot upload them elsewhere. I come back to you next week.

Ok could you please try these driver package here: http://forum.xda-developers.com/galaxy-nexus/development/adb-fb-apx-driver-universal-naked-t1379875
Follow the instructions there for installing
The next step (if the driver would work for you) will be to flash a working PIT to your device to make sure you are using the correct partitions.
Afterwards we will flash the bootloader (may absolutely brick your device if not done correctly) and then --> if all goes fine --> you should be able to flash in download mode whatever you want to.
So it is still a long way to go and I need to check all the steps first before actually we can proceed.
That may take longer so do not expect that this will be something in the next days.. sorry.
Update:
If the above universal driver do NOT work for you: Test these one here View attachment apx_driver_samsung.zip

Thanks for the speedy reply Sir......Ill do as you said and let you know Sir......thank you.....thank you.....thank you Sir....
wooowwww......windows installed the drivers for the phone and it shows up as "NVIDIA usb boot-recovery for mobile devices." But when I open minimal adb and fastboot and type 'adb devices' the phone doesn't show up in the 'list of devices attached'....the line after 'list of devices attached' is just empty.....Also the phone doesnt show up in odin....what should I do next Sir?

nvidia apx isnt fastboot/adb device. You can found tool on nvidia site ( more info https://ac100.grandou.net/nvflash ), this tool can read and write whole flash.
Before you could use nvidia's tool, you must send an uniq blob to your phone. APX mode is useless without this blob.
This blob is uniq for every phone.
I have created boot recovery files based on Samsung's pdf titled "[14-96]_Boot_Recovery_Guide_Qualcomm_APQ8084_[includes_SM-N910F]__Rev_3.0"
These were done on a 32gb clas 10 microSD, they are imaged to a file via Norton Ghost portable (GHO file.
If your note doesn't boot, that might help. (No charging light, PC detects as QHUSB 9008 mode etc)
Download these GHO files and norton ghost portable.
Insert an empty microSD, Open norton ghost > Local>Image>to Disk the choose your microSD.
Your disk capacity might show up less, but don't worry, you can restore later on with Minitools (Check online on how to use).
I have also created an eMMC backup image of n910p running MM (PE2 build version)
It's a 2gb file, on unzipping with 7zip, around 4gb. (While creating, the output from adb shell is shown in the pick. Not sure if it's an error... is it supposed to be bigger? it was on a clean stock but rooted.. no user content)
Follow this guide http://www.droidsavvy.com/unbrick-qualcomm-mobiles/ to check it's in new 9008 mode.
Then my file might work for you.
All files are at https://mega.nz/#F!qRAGBZDY!_k24QWYaA0We2IQoAgE2Ng
Hi,
and Thanks
Well I have tried these Gho files but no joy. Ghost says file sizes are 19. After writing to the mirco SDCard there is no spaced used and 3 folders that are blank.
I am looking for these files below to recover to use QPST (QFIL) / MiFlash , maybe you can extract them from your device but I have no idea how to do it.
MPRG8084.hex
-8084_msimage.mbn
-rawprogram_32GB.xml
-patch0.xml
-Settings.xml
Thanks

And my phone its same
I hope to find way to solve it
i have also same issue does any one solve ?
an interesting read... curious, under what circumstances would this be more convenient / more practical than a simple odin flash?
is this supposed to recover hard bricks / bad bootloaders?
Took N910P back to Sprint.
I experienced my problem when I was using my secondary (not activated, clean esn) Sprint N910P as an MP3/MP4 player. After the last update which i don't know... it would not boot into the OS after the Sprint splash screen, so it would continue to do this constantly after removing the battery and rebooting even after optimizing apps screen. I researched and found XDAs forums with a lot of How tos, troubleshooting and workarounds. Long story short the Reactivation Lock was not disabled and even using the techniques supplied here I did not have any success.
I took it to the Sprint store and they deactivated my Primary LGV20 and activated the Note 4 so they could service it and then flash it to the current OS. They couldn't flash it and were going to have to send if off to replace the motherboard or replace the phone. The tech told me that this has been happening to Sprint Note 4 phones after an update and since it was a update error there will be not charge to me. Now I had insurance on the Note 4 for six years prior to upgrading to the LGV20, so they had to activate it to be able to service it. I will update their findings when i receive my phone in 7 to 10 days.
I pray this helps someone in my situation, as for me it is bittersweet. I didn't fix my phone but I found a new forum and I can tell everyone here is as passionate about what they do as I am!

So i got one of these vs985s. and nothing. screen lit up but nothing else.
so i had a unknown or damaged usb device .long story short
got it in 9008 i follow all the guides emmc and ap test past.
but when i to the sd ram test i get a error of
========DDR TEST START
Test level = 0(check data/address line)
sbl1 partition write FAIL.. senctor 0x28000
WRITE FAIL During ddr test..
Aborted..........
Also everytime i click a restore boot image in any version of board diag tool whatever partition im trying to restore write fails....
Now i remeber back on my g2 i got the 9006 mode i was able to zero all the partitions in linux when it mounted 30 somthin drives.
Is there any info any one could give me as i have followed all the guides.. But might be missing something somewhere.
any help is greatly appreiciated
I have the exact same problem here with my father in law's D852. The phone was never rooted. I was trying to unbrick it but it didn't reboot after flashing sbl1. So I decided to try a stock rom form another source and that's when this happened. Trying to go back to the first rom didn't work, even after erasing the entire emmc. My guess is somehow, we activated permanent paper weight mode. I hope someone more qualified than us can help us, or at least confirm our phones are good for recycling...
I need help with my pixel (taimen), and I don't know what to do. In attempt of resizing partitions with help of parted, I somehow deleted all the partitions (even though it showed they were recreated successfully), and now the phone won't even boot to fastboot. Is there any way how to repair it? I've had it for long time and I don't feel like loosing it today.
There are a couple of other threads where a user posted firebase files that could be used with existing firmware. Those files and a copy of MiFlash on the PC may be able to restore the device, but only if it shows up as a Qualcomm USB loader in Windows. The only other alternatives are to pay Google to fix the problem or sell the unit for parts.
