Hi [MENTION=8052153]toy_story[/MENTION]

Many thanks. Will look into your info.

[Galaxy S II General] Bootload٠:
Thank you

. Many thanks. My mother's phone stuck at system.img I used everything you said. Also pit files and even patched Odins and combination files. The phone is soft bricked for 3years now. While my mother was using it. Maybe she clicked on a malware ads or OTA caused the brick. I doubt a malware can damage the phone because it is not rooted. My mom does not know this things, she just use YouTube and whatup.

I had to take it to Samsung service insisting that the OTA, update to android 8 caused the problem. And try to solve it for free. The technician told her, she needs a new motherboard for the phone. But it is not hard bricked. Just fro lock and locked bootloader, plus odin secure download enabled.Samsung Galaxy J710F region Morocco I copied the Pda from the recovery mode (I used an app to access it, ultfone) because it was impossible through buttons the keys redirect me to the notice to use smart switch, but the latter app could not even recognize my device. then google it (thepda code) I got some 12 stock Roms I used IDM to download them all at once, done in 1 hour , stable connection not very strong " Idm helps " really.!

So all stocks stuck in system.img. then fail at (XmitData_write)

Now I managed to visit cyber cafe to try many computers and ask for Samsung Usbs there. I bought a new one usb2 but it did not help. I'm also thinking to use Jtag. Flash recovery alone if fastboot helps. But bootloader is locked. Flash kernel if possible and other tricks-suggested. I won't give up. Since I'm able to access download mode it is fine. I check if file is corrupt. I always get one error ( there are some data after the end of the payload data)

Thanks for this guide. In case anyone is trying to flash back to stock firmware after coming from Lineage 17, 18, 19 etc... and needs to repartition with a PIT file back to its original state (using Odin 3.07) along with STOCK firmware, I found this link to the PIT file from another thread: https://xdaforums.com/t/mod-guide-p...ement-pit-files.2538947/page-69#post-84556131

Updated OP to include an Odin flashable, 4.2.2 kernel (Dorimanx 9.34, .tar extension). It's recently been released by Dori, hence OP updated to reflect this.

Thanks for all the info, exactly what I need ;p

Just fullwiped and flashed a new rom, but it doesn't boot (kernel panic) and booting into recovery gets stuck at samsung logo.

So usb debugging is off (**** cm kernels) becuz I fullwiped. And downloadmode doesn't recognize the phone, I'll try all the steps when I get time. but you think odin is possible without usb debugging on ?

My usb also disconnected allot lately, until a few days ago no connection, (maybe cuz of xperia drivers/fastboot i had to install to root it) but charged fine, I've changed the usb board before and made it clean now. it connects fine but it cannot install the base system drivers.. (my guess is becuz usb debugging is off)

I'll try uninstalling all the drivers, and if needed a re-install of windows, to make sure no other device drivers are left
[Galaxy S II General] Hopper8:
Yes, you can definitely flash via Odin with usb debugging disabled. Definitely uninstall all the drivers completely & then reinstall (there's a few tools in OP to help with that). Don't try flashing until you're certain that you have a stable usb connection pc-phone... Without that, flashing will fail.

So yes, you're on the money with the drivers. If you have troubles with them still, you could always use a friend's computer for a little while.

Sorry to say, but if you really have tried absolutely everything that's listed, multiple times, and nothing works... Then as Andrew has said, unfortunately that's a motherboard replacement. Only go down that path if you're certain there is nothing else to try. Sorry

hi, i tried all of the above. and stiil nothing is working. i DL mode on every try i get a new count

CUSTOM BINARY DOWNLOAD: YES (8 COUNTS)

before i tried my first time, i still had cmw, and then i saw that everthing is unmounted. maybe i need to re-partition with PIT file? its the last resort..

(and flashing with odin works fine on my s4 , so its for sure the device.)
[Galaxy S II General] Hopper8:
Sorry for the slow reply, I haven't been able to go online much lately. To be honest, I'd still stay clear of the pit file, and try to flash the 3part firmware over again. A lot of people have success flashing that when nothing else will. If you really can't get it going again, then a pit file flash may be worth a shot. But do bear in mind, if it fails, you'll need a new motherboard.
[Galaxy S II General] Firoz24:
pls help me im getting this error
[Galaxy S II General] Hopper8:
That's a new one, usually it will fail at nand write start, but yours fails on the step right after that.

What file are you flashing, and what file extension does it have? And then also, you do have an i9100 right? Not a variant of it (i9100 etc).

If you do have an i9100, I'd try flashing the 3 part firmware which is linked in the guide.

[Galaxy S II General] Hopper8:
I just saw now that you've opened another thread in Q&A, asking the exact same questions. Please don't double post, the same people read all the posts anyway. As it has been said already though, there is no "magic fix". You need to keep trying everything that's listed off here, or there's no fixing it. If you really have tried absolutely everything, multiple times, then as has been said, take it to a service centre.
[Galaxy S II General] Firoz24:
problem solved. i have installed by my friend's pc. No error, it got installed. thanx for helping
[Galaxy S II General] Hopper8:
Ah there you go. Good job persevering. That's what I meant by trying absolutely everything. It seems with Odin that you can do most things over again, but it's the only one you don't try that makes it work. Don't miss any out!

From bad to worse

Hello all,

Thanks for all the advice on this forum. It's been quite a journey.

Problem: Soft brick - phone boot fails with 'phone / orange triangle / computer' icon. Can only enter Download mode.

Previous problem: Boot loop.

Currently, Kernel flash stops at "NAND write Start!!" and ROM flash freezes at "factoryfs.img" or "cache.img" (depending on ROM)

How I got here:

Was running with stock JB. When updating apps many would give an error saying Not Enough Storage Space. Simplest solution I could find was to dial *#9900#, and selected option 2 “Delete dumpstate/logcat” - freed up space, happy days.

Two weeks later I was typing an email and my phone reset and got stuck with a boot loop (unsure if related to above step). I could get into Recovery Mode (periodically) and Download Mode. I tried leaving the battery out over night - however, still got bootloop.

I then tried to Wipe Cache Partition in Recovery mode. This appeared to freeze on me, and I pulled out the battery (I waited about a minute - perhaps my downfall?). Recovery mode would then start loading and bomb out.

Then tried to flash a stock South African ROM (where I live). However I think the phone was from Nordic region (bought on an auction website). Froze at "factoryfs.img" or "cache.img" (ROM dependent)

'phone / orange triangle / computer' icon then appeared.

What I've tried - flashing with:

Multiple ROMS

Multiple Kernels

Multiple versions of Odin

Different Computers

Different USB Cables / Ports

Still to try:

Completely uninstalling Kies - installing S2 USB drivers only (and repeating above process).

Attempting 3 part firmware

European ROMS

If that fails, I'll look into the PIT option... or service centre.

Would pulling the battery during a Wipe Cache Partition somehow not allow me to flash kernels and roms?

Any other thoughts?
[Galaxy S II General] andrewwright:
Nand write fail =new mother board.

You can try pit file but I doubt it will work.
[Galaxy S II General] Hopper8:
I'd definitely not give up until you've flashed the 3 part firmware. As hotfile is down (hosting site) google search for XXLSJ firmware i9100. Hopefully you find a working download link. Concerning pulling the battery whilst flashing, don't. It could have the same effect as pulling the cable during a flash = hardbrick.

I just had a google, I can't find any links to XXLSJ which aren't down. I may have missed one, but it seems to me that all the download links point to hotfile.

Hmm.... Now to find an alternative 3 part firmware, which is still online... [MENTION=4905463]electricsheepdreamer[/MENTION] or [MENTION=4229457]It_ler[/MENTION], any suggestions?

Sent from a galaxy far, far away
[Galaxy S II General] It_ler:
Why do you need XXLSJ ?

It was only an unofficial test version of the first "leaked" Android 4.1.2 stock ROM for the GT-I9100.

I've googled it and found also some torrent download links ... as I don't want to go back and flash this version, I haven't tested if these links are still working.

EDIT:

OK, I think now I got you.

You want a 3-part stock firmware ... Android 4.1.2 ... for flashing in PC version of ODIN.

Let me check ... maybe you can separate the different ROM files of a 1-part tar file.

I found XXLPH as 3-part firmware ... but it's Android 4.0.3.

EDIT 2:

I found XXLSJ as 3-part firmware on my external hdd.

Will upload it to my dev-host and add the link here as soon as the upload is finished.

... may take a few hours ... unfortunately.

EDIT 3:

Here is the 3-part firmware for the unofficial/leaked Android 4.1.2 test ROM XXLSJ.

(Link removed !)

As it contains a data.img file, it will overwrite/wipe your data partition = factory reset.

You will lose your settings, apps + app data, etc.

I recommend to use this firmware version only for "repairing" your international SGS2 (GT-I9100).

After that, you should flash another firmware and/or restore your backup(s).

[Galaxy S II General] Waceman:
even worse

Hey guys,

Thank you all for your input.

In summary, I have made things even worse. Odin no longer recognizes my phone.

Steps I took:

So I used this 3 part firmware found online (can't post the link)

Used the PDA, CSC, and Modem files... and it seemed to flash everything up to the kernel (zImage)... left if for 45 mins.. but nothing happened.

Then tried the 3 part firmware provided on this forum - thanks for providing it guys. Also, stuck on the kernel flashing.

Then went back to the original multi-part firmware and included the bootloader... got stuck on the bootloader.

Tried again and got stuck on bootloader...

Switched phone off and now odin doesn't recognize phone (still can get into download mode).

:(
[Galaxy S II General] andrewwright:
Its a nand write problem so it wont flash. Best bet is either start to look at pit to repartion bad blocks. May not work either.. or mb replacement. But do keep trying to flash the 3 part fw . Dont give up on the first try. :thumbup:
[Galaxy S II General] Hopper8:
As andrewwright said, don't give up yet! My first port of call would be to try a friend's computer. Hopefully that will recognise your phone with the correct drivers installed.

[Galaxy S II General] Waceman:
Hi guys,

Thanks for the encouragement!

I tried the phone on a friends PC and it found it. We tried many different things... even Heimdall. Kernels, bootloaders, and the PIT! But it just seems that whatever we try can't be written. Even after having rebooted my phone after a failed PIT my phone could get into download mode.

Friend's conclusion is that some part of the usb is not working (we tried 4 different cables) - and think it's the socket that's perhaps not making full contact? Saw a post somewhere about cleaning it out with a cotton bud.

So may try that next...
[Galaxy S II General] keithross39:
Not a good idea.....the cotton bud is too large....you will have to push it in too hard in order for it to have any effect. This could make things worse.....you'd be better off with an old toothbrush.....you might end up having to replace the port........

This might be my S2, or it might be my W...but it's definitely CM
[Galaxy S II General] andrewwright:
Have you tried a kernel flash? Did it fail on pit file?
[Galaxy S II General] electricsheepdreamer:
Hi Waceman, speaking of which, check this post and see if you experienced anything similar.

http://xdaforums.com/showpost.php?p=30290884&postcount=3619.

Regarding your case, for as much as I can see, bootloop you got in the first place is what happens on stock kernel after a sudden power loss occurs and wiping data partition/factory reset is what should have solved it.

But phone freezing while wiping cache from Recovery is what worries me the most.

Anyway, best of luck and don't give up. :thumbup:

(Also try to uninstall Samsung drivers with Revo uninstaller and install v.1.5.27.0. that you can find if you tap my sig and navigate back).

Yes, after ROMS failed I tried a kernel flash, which also didn't conclude.

PIT also got stuck... but after rebooting - my phone wasn't dead.

Something is being written though - as my error logo changed from a small compact orange triangle to a large yellowish one with text (surprisingly this gave me some joy - haha)

Thanks [MENTION=4905463]electricsheepdreamer[/MENTION], I'll look into the broken usb port issue.
[Galaxy S II General] Hopper8:
Good job persevering, Waceman. Just wondering, after the kernel flash, you say something is being written. What happens if you try to boot into recovery mode (instead of download mode)? If by some miracle you have a working custom recovery, then try flashing a custom ROM zip file from recovery. But, definitely look into the usb port replacement.

An update:

I removed the drivers using Revo_Uninstaller. And installed 1.5.27 Samsung USB drivers.

Managed to clean the usb port more than I thought - using a toothbrush (a friend, offering much sympathy, assisted).

USB cables clip in a lot deeper - and crisper...

Alas, everything I try just gets stuck even when I flash individually. CSC, Modem, CODE, ROM, BOOTLOADER... It also seems my Custom Binary Counts has stopped at 29... so that's not updating too.

I will try another computer tomorrow...
[Galaxy S II General] Hopper8:
Good job, sorry to hear that you haven't cracked it yet.

Still trying...

Hi guys,

An update: I'm still trying to recover my phone #neversaydie!

I've tried the Heimdall route (Windows 7 mostly, but also tried Linux). For Windows 7: Removed all drivers using Revo Uninstaller. Didn't install new Samsung drivers, but rather used the one's tha Heimdall installed: "WinUSB (v6.1.7600.16385)". Although it didn't find my device as "Samsung USB Composite Device" - but rather "Gadget Serial". So have attempted to flash individual files, one at a time. This is what happened:

boot.bin = successful

param.ifs = successful

sbl.bin = stuck at 100%

modem.bin = stuck at 100%

zImage = stuck at 100%

cache.img = stuck at 100%

hidden.img = stuck at 25% (~100mb uploaded)

factoryfs.img = stuck at 21% (~100mb uploaded)

Trying to upload the PIT file also fails. However, downloading my device's PIT file is successful.

After the files get stuck, Heimdall reports "ERROR: Failed to confirm end of file transfer sequence!"

My bootup logo has gone back to the Samsung Galaxy SII logo (instead of the firmware error logo).

Really thinking there's a hardware fault (remember dropping my phone on tiles on the day / day before it started its nonsense). Going to take it in to the service centre on Friday.
[Galaxy S II General] Hopper8:
It really is looking that way isn't it. You've done everything possible pretty much. Good job persevering :) I'm sorry that it hasn't worked out for you with a functional phone. Let us know how you get on at the service centre?
