Solution: Recovering from soft brick

I faced a unique problem today...
1. Got a notification to update Super Su
2. After updating, went to the app and it asked for updating binary...clicked Ok
3. Asked which method to use- Normal or CWM/TWRP...clicked CWM/TWRP
And all hell broke loose...the phone rebooted and kept stuck at Samsung GT-N7000 screen
Tried booting into recovery using the Vol Up+Menu+Power Button but failed to boot into recovery and always booted in the same GT N7000 screen
In short my custom recovery was messed up...
The above may not be a huge problem for people frequenting these forums and having basic google search finesse, but still it took me more than 3 hours to un-brick my phone after trying several combinations and permutations, so to the benefit of other members here's my simple solution:
1. Check if you can get into download mode by using Volume Down+Menu+Power Button
2. If not, your problem might be more serious and you should keep searching for a solution...best of luck!
3. If you can get into download mode, fine ...lets continue...
4. Prepare your PC for flashing a custom recovery via PC Odin:
a. Download PC Odin: I used Odin 3 V 1.85
b. Download a custom recovery: I used Philz 5.03
c. Uninstall Kies and Samsung Drivers from your PC (do it, it worked for me!)
d. Install latest Samsung Drivers afresh
e. Eject and physically remove all USB connected devices from your PC
f. Disable any antivirus software
5. Now get to download mode on your handset- after Volume Down+Menu+Power Button- on the next screen press Vol Up key to enable download mode. Do not connect phone to PC yet.
6. Run Odin as administrator. Let the app window come up on your screen.
7. Connect the original Samsung USB cable to the USB port at the back of your PC- this is to ensure it gets connected to the motherboard USB slot directly- please do this- critically important- at least in my case. For a laptop, I guess any port will do.
8. Connect your phone to the PC using USB cable
9. The ID:COM indicator on the PC ODIN window should turn yellow in a few minutes
10. Do not click on any buttons on ODIN Window- Auto-Reboot and F.Reset Timer should be checked and everything else should be left unchecked.
11. Click on PDA tab on ODIN and browse to the custom recovery tar file, select it- it should now appear under PDA tab.
12. Click on start and let ODIN do its thing...
13. Disconnect the phone after successful reboot.
The above steps helped me recover my soft-bricked phone.
I understand you should follow the steps verbatim to use this method...believe me I have tried several iterations- using front USB port, trying without disconnecting all other devices from USB port, without uninstalling Kies, et al...and failed everytime.
I hope this helps you.

[Q] No SIM Message After Installing Latest CM10.1.3

Hello.
I recently installed CM10.1.3 on my GT-I9000 running stock GB. I did everything according to the instructions (though, mind you, this was not my first time installing a ROM just the first time on this device).
When I booted and tried to set up a CM account it gave me a message saying "Insert SIM card". I tried installing the kernel again, as well as installing other ROMs (AOKP mostly).
Nothing seems to work. It will simply not recognize my SIM.
Any suggestions?
Thanks!

since its the first time on this device, can you check IF sim card is inserted in the correct direction

Yes. It is.
Might be also worth mentioning that I tried it with a few different cards, all of which work with other devices, and not with this one.

you can try taking it back to stock ROM , you can follow this but it sounds like you may have hardware problem, if that fails as sim contacts can get broken or damaged too and can be replaced. so best to test with Stock ROM to check if its a software or hardware problem. also try to flash without SIM card and insert after flashing and first boot.

For a clean install and root, flash JVU ROM and its CF_root, as it is easy and problem free. I never had any problem with JVU
The whole procedure is given below
FLASHING JVU ROM WITH ODIN v1.85:
1. Install USB drivers for i9000 on PC (ignore if already installed) and restart computer to take effect
2. Turn off your phone and put it in download mode
by holding VOL DOWN+MENU+POWER
Do you get the Yellow Triangle?..If so
continue..if not do it again...
3. Plug in Phone with USB Cable To Computer.
4. In ID:COM it should go yellow and you should see
ADDED in the message box
5. Check Re-Partition option and then Click PIT
button to select: s1_odin_20100xxx.pit file.
6. Click PDA button and select :
CODE_I9000XXJVU_xxxxx.tar
7. Click PHONE button and select:
MODEM_I9000XXJVU_xxxxx.tar
8. Click CSC button and select:
GT-I9000-CSC-MULTI-OXAJVU.tar
9. When you have all the files needed in ODIN,
Click Start and let it Run
10. Once complete you will see S logo on phone
(computer will make a few noises like connect/
disconnecting
11.Unplug the Cable to the Phone
You will see your phone working excellent. Now it's time for rooting
Procedure for rooting:
1. Power Off Phone
2. Download CF-Root kernel first.
Unzip the file to a folder. You
will get the .tar file – CF-Root-
XX_OXA_JVU_2.3.6-v4.3-CWM3RFS.tar
— inside the extracted folder. DO NOT extract
the .tar file (even if you see it as a zip
file, which it is not). You need to flash
the .tar file using Odin to gain root
access and install the ClockworkMod
Recovery (CWM) alongside. If you’re
getting zimage file, it means you’ve
extracted the .tar file too! — and that’s
not a right thing to do.
3. Boot your phone in Download Mode —
Press and hold volume down+HOME
+POWER keys together.
4. Open Odin now. Connect your phone to PC now. You’ll notice “Added! !” message in the Odin’s message box in the bottom left.
5. On Odin, click the PDA tab and select the .tar file you got in step 2 — CF-Root-XX_OXA_JVU_2.3.6-v4.3-
CWM3RFS.tar
6. Make sure “Re-Partition” checkbox is not selected. Leave the “Auto Reboot” and “F. Reset Time” checkboxes selected.
7. Click the Start button on Odin to flash the CF-Root kernel. After the CF Root is installed, phone will restart automatically. When you see the PASS written in top left box, you can remove the cable.
8. Your phone is rooted now. That surperuser app is there! The CWM app is also there, and
clockworkmod based recovery has
been installed too. Now you enter the custom ROM world without worries. Enjoy!

But the hardware was functioning perfectly well before I flashed. Why would flashing a ROM damage my SIM contacts? (or any hardware, for that matter)?

I assume you have a software issue, that's why I asked you to revert to Stock ROM after you confirmed the SIM card was not inserted the wrong way round. , only IF the sock ROM also gave you that result than you need to consider hardware, as I have not heard of anyone having this issue after flashing CM 10.
AS for PIT file its in 4Shared site, all they would require is you should be a member and register with them ( you can do that with any name and password) the ROM site is FileRio, there you should only use free download button , clicked a number of times ( same button) for download to begin, both uploads were by me, so its virus free. I will upload pit file to the thread asap as its very small file.
EDIT: already uploaded PIT File to thread uploaded 3 PIT files in a package used for i9000, only use 512

Hey. Thanks again.
One more problem, and it's a big one:
Odin won't respond to my device. No yellow rectangle, or any kind of response...
What can I do to make it realize that it's there?

the guide to solve such problems is right on top (begining) of that thread
Note:- It's assumed that you can and know how to connect your Phone to PC with USB cable . If you do not know, first install Samsung USB drivers on your PC/Laptop, than enable USB debugging on your phone by settings menu>Developer options> tick USB Debugging. After this use only Samsung USB cable and plug it into your phone micro USB port and to your PC USB Port. ( Always use the Back USB port on PC as some ports may not connect well enough for flashing ROM's. )
If unable to connect your phone to PC for any reason, refer to this guide

I tried everything in that guide, and it still the same.
Might be worth noting that the computer totally does recognize the device. I mean, I can access the internal SD from the computer, when the phone is on. It's just that when I connect it in download mode, Odin doesn't respond.
Might also be worth to stress that I used Heimdall to flash the recovery, when I did it. Could it be related to why I can't use Odin now?

And another thing regarding my main issue - could the "Insert SIM" message be a modem thing?

The password for XXJVU is samfirmware.com
If you are still unable to open this, then download XXJVU by Google searching and then try. This is the best way to get rid of the problem.
If you are able to go to download mode, install USB drivers for Samsung and restart PC . Now exit the Kies program and its related services from your PC. If you are using windows, you may find the tray icon and exit by right clicking. Now run Odin and flash.
If you are not able to go to download mode then search "homemade usb jig" and use the jig method described in those threads.

I'm trying to download the XXJVU again. Will see how goes.
I am able to go to download mode. So that's not it. I also don't have Kies installed on my computer, so that's also not it. I installed a few different Samsung drivers, and did the whole process a few times. The computer always recognizes the phone, but Odin doesn't.

I don't get why I can't delete stuff, if I accidentally posted twice. Anyway - feel free to disregard this one. Sorry for spamming..

OK. Managed to open the XXJVU.
Still have the problem with Odin not paying attention to my phone being there. Do you think it might be a problem with dl mode, that I should try fix with a jig (the phone does act LIKE it in dl mode - yellow triangle and all...)?

You seem to be having strange problems. I assume you pressed the correct combo keys ( as shown in image on that thread) and you did not get download mode ( this could be due to ) you don't have an i9000 but a different version of Galaxy S? or your keys are not functioning or you have a wrong bootloader
so use this methods & tool from PC to boot into download mode after you are sure you have an i9000 international version by checking under the battery. just to give you an idea , read this
Odin will only connect when phone is in Download mode, so as you mentioned you have NO problem with drivers and PC, its only your phone not being able to enter download mode.

You assume correctly - I did use the correct combo. And the battery says I have an GT-I9000. I think that's only the int'l version, isn't it?

I will try the ADB solution tomorrow. But doesn't the fact that the phone displays the download mode screen say that it is indeed in that mode? (because it does display it, as I mentioned above). I mean - is it possible that the phone seems like it is in download mode, when it's actually not?
Thanks!

hmm, i got the impression that you are not getting the download mode display , if it does than it is in download mode, so now you need to check your Odin3 download, what version are you using , try and download again and always use fresh Odin3, meaning, if it had a problem or even when no problem restart it a fresh. And best install Samsung USB drivers again ( link on that thread), if that did not solve it.
Check this out! You , YES! you are an " Android ". Not your phone but U.​

I tried both versions that from here (i.e. v1.83 and v1.85). I'm not really doing anything else with Odin, so there's nothing to restart.
I also tried uninstalling and installing the drivers a few times, using a few different installation files, and by letting windows figure out on its own which drivers to install.
Non of it changed the result.

this is weird, anyway since heimdall is possible, right? try and download a heimdall rescue kit from MY Android collections and try flashing , if the phone boots you can also install Mobile Odin from playstore to flash stock ROM too.

Yup I lost imei but recover it now my phone is functioning in PDA mode I dont have nerwork

try to flash the efs saving zip in the forum,may save you a cost service
Sent from my GT-I9305

I'm curious, can't he add the IMEI since it's available on the phone under the battery?
Can't it be restored with full wipe of internal storage and flash with Odin?

im having the same problem my imei shows unkown along with other stuff and my network signals dont show. maybe the reason for my problem could be that i might have done a couple of resets in the previous week idk

Recovering IMEI And Data Connection :
•Make sure you have Samsung Kies or the Samsung USB Driver installed on your PC.
•Download and Extract: Odin3 3.04.zip - 457.11 KB to your PC if you don't already have it.
•Download and Extract: Param_Bin_I9305.zip - 612.14 KB to your PC.http://d-h.st/Fhb
•With your Phone Switched Off, press and hold: 'VOL DN' + 'HOME' + 'POWER' to enter Download Mode.
•Connect your phone to your PC via USB Cable and start Odin.
•Check your phone is connected by seeing if a COM Port in a Blue box is present under ID:COM.
•Press the 'PDA' Button and select the 'Param_Bin_I9305.tar.md5' file you extracted from the Zip Archive earlier.
•Press the 'Start' Button and wait for it to finish flashing. If successful, you will see a Green Box with 'PASS!'.
•Wait for your phone to reboot then go to your Dialer and press: *#06#. You should now see your IMEI and your Data Connection will be back.

Having problems installing ROM.

Okay so i did something dumb and I'm wondering if there is a way out. I just got my second Note 5 because I dropped my first one and the screen went black. It was gonna be cheaper and easier to just buy a new device than actually repairing all the damage.
I installed TWRP through Odin. Stupidly, I did a complete wipe, including internal storage, and now I can't get the device to see the USB/OTG. I have a new cable on the way that's going to get here tomorrow. I can't think of what else it could be? Any ideas would be much appreciated. It doesn't have an OS so I'm thinking I may have wasted 250$.
It's not turbo charging either so could It be the charging port that's causing it to not be picking up the OTG?

Does Odin recognize it at least in download mode?

Have you tried mount on as usb in twrp?
press install>select storage then there will be two option
Internal storage and USB storage. Click on USB and the value will change from 0 to the amount of gb your otg have,then you can flash via otg

Step 3 from the other guy's post above you. That's what I was gonna help you with because you wiped the internal storage. Odin will still recognize it but in Download mode and she won't work again unless you flash the stock firmware specifically for your phone from the link above.

Fixed
I reOdined and same problem so I went back and looked at the instructions. I saw that you had to have MM flashed onto the device so I tried that and it worked. I just figured updating the phone would give me enough but it didn't. Thanks for all the help guys!

Blue Light flash

Hey all,
I have Zuk z2pro z2121. I wanted more than stock ROM so I downloaded zui 2.5.344. I unlocked bootloader n rooted my phone as well as installed TWRP. "Tool All in one" PC software helped me to carry out above with ease.
While playing around I clicked "Lock Bootloader" and phone got switched off with indicating continuous blue light. I tried pressing vol down + power + Home button, and several other combination but didn't help. When I pressed power button for long, I got Zuk logo onscreen with a white flash on indicator for 1 sec and then again the blue light indicator.
After a little RnD after pressing power button till I got white flash for 3 times and the blue light got completely off. I don't know what to do further. I have backup of my boot , recovery and ROM. Kindly suggest.
Shoaib

Press and hold volume - and power . Release power, after vibration you can release the volume -. You will be in that menu https://ibb.co/f3vOHm . Go to device manager and check if pc recognize your phone https://ibb.co/bHqZOR . Open CMD in adb folder and write adb devices https://ibb.co/cwCg3R . Then adb reboot edl . You are i EDL https://ibb.co/cvjiHm . Use Qfil to flash stock rom

Didn't work...
Thanks for responding. As said, tried pressing Vol + Power and never got any vibrations. Tried Up vol + power, tried Down vol + power. No vibrations.
When I press power button with any combination, this is what happens,
After Approx 15 secs - 1 white light flash in place of blue along with ZUK pic on d display (stays approx 1 sec)
Still keeping power button pressed
After approx 7-8 secs - same as above
Still keeping power button pressed
After Approx 15 secs - 1 white light flash in place of blue along with ZUK pic on d display (stays approx 1 sec)
But now after this third time of flash, blue light appears and after 4-5 secs disssappears. If I leave the button only at this time, the blue light doesn't comes back.
If I leave the power button before or after this sequence, the blue light doeanon the indicator doesn't goes off at all.

What is happening when you connect phone with pc ? Is there any reaction ?

No reaction from PC.
I tried connecting to PC, earlier Tool all in one immediately use to detect, n now there is no response from the PC or the software after making USB connection.

Sir,
As I said earlier, I clicked lock bootloader, n when the screen went off, I disconnected the phone from PC. There is a possibility of the boot partition getting damaged or so. Kindly assist.

There aren't any ways to enter in fastboot or recovery , even in service menu . I think you should try deep flash cable to enter in EDL .

Will do as u say. Just one last thing, when I checked device manager in my PC, it showed the phone as other devicez "QUSB XXXX". Question is,
1. Any possibilities of recovery without going for a deep flash, as I got to learn it first.
2. Other part is, my phones battery seems to be drained now. So, it won't be a problem for a deep flash.

Could you give some print screen ?

The matter is that you must switch your phone to edl . Try this yet . Your phone must be turn off .
Press only volume up button for 10 sec and while keeping it pressed,connect phone to PC . Hold volume up until your PC finds a new hardware . It should be android phone - ShenQi composite adb interface . If it doesn't work I have no more ideas apart from df cable . This cable works on Zuk z2 and I think it should works on our Zuk z2 pro

Sir,
I managed to connect the phone via USB as 9008. Miflash not supporting my ROM. Will download Stock ROM n then try with QFIL and MiFlash as well. Thanks for all your support. Will keep u posted about the progres. XML file is not found in any ROMs I have. Miflash some error also but detecting the device. Is there any other tool similar to Miflash, which I can try..

First use QPST/Qfil . Follow this guide https://zukfans.eu/community/threads/howto-flash-a-stock-zui-rom-zuk-z2-pro-z2121-only.57/
Do all steps .

Good day.
I tried QFIL as well as Mi flash tool. Both showing errors. QFIL displaying Qualcomm HS USB QLoader 9008. But when downloading content , it shows Sahara error with even initiating the installation. After browsing a bit, started eMMC software download, and found displaying COM20 No phone connected. Can u assist me to fix this. I mean the phone must be in download mode. But how ?
Miflash, on the other hand shows Hello packet error. Don't know how to fix.
Things I did to fix above errors,
1. Copied ROM to Qualcomm/ bin file
2. Copied ROM to C:/
3. Tried using different USB ports
4. Tried different USB cables
5. Uninstalled n reinstalled USB driver, adb n fastboot, qpst, n miflash many a times along with restarting my PC.
None of the above helped.
I think, if eMMC software download starts displaying COM20 Phone connected, then the issue might be sorted out.
Kindly assist.

U need ufs flash not emmc. Change programmer in qfil.

I have a some experience with miflash but I use it for xiaomi . I've never flashed my zuk z2 pro by miflash . If you want to use miflash use 2016.03.30 and run it on PC with win 64 . Create a folder on c: for example "zuk" and copy to that all contents of unrar Qpst/Qfil zui rom . If you have Qualcomm hs usb 9008 that means your phone is in edl ( download mode ) . Good luck

I appreciate all ur support....
As suggested, tried Miflash 30.03.2016 also. This ones showing class not registered.
No of things i did to overcome this errors.
1. Changed my PC to developer mode. Allowed portable device connections n stuff.
2. Visual studio C++ 2010 was installed along with Qualcomm driver, i believe thats sufficient.
3. Disabled my Firewall.
4. Downloaded n copied some atl70.dll file to my syswow64 folder as well as sys32 folder.
Tried all flash tools again after these changes....Same negative results.
Any further advices !!!
Regards

It's fault of drivers . Go to device manager and chose qualcomm hs usb 9800 and update driver automaticly . The second matter concerning of flashing by qpst/qfil - why did you put rom in qpst location ? . It must be for example on desktop in one folder . The simplest path is better . Don't use spacebar . Load content you must chose from that rom . Don't use other location . It's not necessary . Could you give some screenshots with qfil errors
