[Q] Need to restore the 930A LG Gpad 10 - G Pad 10.1 Q&A, Help & Troubleshooting

I reset my GPad10 to sell, but the new owner can't get past the logon screen. It wants my email and password, I am not giving that away. Is there a way around it? I called AT&T and they suggest I wait 24 hours (I changed my password) and logon, then change the info once inside. Why would I need to do that? I did a factory reset, not any WIndows refresh, it is suppose to be like it came from the factory.

Hi*
V700 USER PLEASE READ !!!!!!
We need an loader image from an working v700 Gpad 10.1 to unbrick" (required:*Root*+ Terminal emulator*App)
in terminal type :
su
(grant*Root)
dd if=/dev/block/mmcblk0 of=/sdcard/loader.img bs=1024 count=168960
Thx in Advance**!!!!

item 9 above, probably best is to try change your cable and reflash stock firmware.
NOTE: after you reflash and able to bootup the phone.... it probably will have 2 issue
1) imei not found and unable to connect to your mobile provider
2) your storage will show only 16GB
IMPORANT: did u do backup for the below block partition ? IF NOT, guess you can only use the phone as tablet.
adb.exe shell su -c "mkdir /sdcard/System/"
adb.exe shell su -c "dd if=/dev/block/mmcblk0p12 of=/sdcard/System/12m9kefs1.img"
adb.exe shell su -c "dd if=/dev/block/mmcblk0p13 of=/sdcard/System/13m9kefs2.img"

1) fast method
probably u can ask ppl with backup of the 240K to send u those backup files
NOTE: if restore from other ppl's backup file you will probably have the same IMEI as the person send u his backup files.
2) long tedios method
its kinda hard to explain here .. but involved using QPST, pull out or backup a .qcn file from your phone and manual edit the IMEI then push it back into your phone.
its a long shots.... but worth a try.
if your phone now still showing 16GB, u can have the 32gb back by formatting the partition.
adb shell
su
stop
/sbin/make_ext4fs /dev/block/platform/msm_sdcc.1/by-name/userdata
reboot
NOTE: above command basically will
1) get adb shell
2) login root shell
3) stop/freeeze the system
4) formate the userdata using ext4 (note all of userdata will be gone)
5) reboot the phone
after reboot you should able to see back the 32gb storage.

[Help] G3 D855 Wifi Mac Address change: why?

I had an Lg G3 D855 32Gb with V10a.
I applied root with purpledrake and I installed TWRP recovery.
By a mistake I made an OTA update that cause bootloop.
After wipe cache and use this command:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
my LG G3 restarts with V10a firmware, but with different WiFi Mac Address.
1) I try to restore my backup made with TWRP;
2) I restore only modem (from backup I made with this command with adb shell:
adb shell
su
dd if=/dev/block/platform/msm_sdcc.1/by-name/modemst1 of=/sdcard/modemst1.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/modemst2 of=/sdcard/modemst2.img)
using adb shell;
3) I try to restore that two img using terminal command shell in TWRP;
4) I try to restore my LG G3 to stock using LG PC Suite restore
but WiFI Mac Address remain different from the original one!
Can you help me to restore original Mac Address?
Thanks!
Enter download mode and flash stock firmware?
Isn't it the same with LGSuite "restore after bad update"???
If not, where can I find the correct firmware for my phone?
Can you explain me?

You destroyed your misc partition, which held your wifi and bt mac's + region info. Which guide did you follow? Who's stupid enough to offer people to wipe phone-unique partition?..
No, it is not recoverable unless you have a backup (or access to LG's service tools).
You can ask someone to send their misc to you, then edit region/imei/mac's information via hex editor.

I made a complete backup with TWRP when I installed it.
Can I use that backup to recover that info, now?

can you share your misc partition? I really want to fix my generic mac address (00:90:4c:c5:12:38) but I have no idea which area to edit since i cant find the address in hex editor.
right now I only have temporary fix by changing my mac address from /data/misc/wifi but it wouldn't stick after reboot. If its too much, maybe just point me where to edit the partition? thanks!

stuck in bootloop and flash tool dont work solution

i really screwed up my d850 att g3. found this on a forum. and it fixed my bootloop. flash tool didnt work for me.
Found this on AndroidCentral: Saved my life – it got my phone back to original. Hope this helps others.
*****************************************************************************************************************
What worked for me was from the TWRP terminal command was to type
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
then hit enter
type
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
then hit enter and reboot.
it booted up to last rom i put on phone.

I belive your commands are incomplete.
dd command basically copies something. "if" stands for input file. What you miss is "of" which stands for output file. Could you provide me with a link to your source thread?
i copied it exactly and my phone booted up right after reboot. i tried flash tool around 50 times on 2 computers and different cables and ports

comment about half way down
If you say so... You could look up dd command or test it for yourself. What you or that guy copied is incomplete, idk how it worked.
Found that comment as well, he says he found it somewhere, no source thread there either.
it did work for me. thats all i can say. i don't know anything about command files.i was trying to get phone out of bootloop for 8 hours. seen this comment tried it and now my phone is working with my last rom i put on it which is cyanide.
found the original post.

Need help, Note 4 SM-N910A

ok here we go, i have a Note 4 sm-n910a and i update to 5.1.1 but when its finish send me a message: "Android is starting... optimizing app 1 of 23" and on 12 of 23 boop, and restart again and again. I try put AP file in ap slot, BL on BL slot, cp on cp and CSC on csc, and finish ok, but when restart do that again and again, even i try puting the pit file but the same, i don´t no what happen (i can´t do downgrade)
There is a solution , or blockage stayed forever? :crying:
One time when I was messing with a hidden menu this happened to me. Phone would only boot loop to the exact spot you're saying. I replied to you in the other thread. If what I said doesn't work you will have to take it in for warranty. I had to take mine in for warranty because of messing with the wrong options in the hidden menu. ATT tried everything including reflashing with their utility and it couldn't fix the issue. So, they gave me a new phone right there. I don't know where you are but if you go to the nearest ATT store they should give the steps on how to get it replaced. Hopefully you have a ATT service center near you so you can just get it replace then and there. Btw, don't mention anything about flashing with Odin. I don't think it violates the warranty since you didn't use custom firmware you just used the official firmware and used Odin which is Samsung software. However don't mention ever using Odin, just say that you had tried upgrading your phone and after the upgrade this happened.

Talking [GUIDE] Fix N910A Boot Loop - Unknown Baseband (step by step)
Hello friends
I have a few people asking questions on solution for N910 boot-loop, I want to make step-by-step guide to answer all questions.
Problem caused by changing *#9090# and possibly downgrade as well.
Takes time, several tries, don't worry.
I had the same problems and this method solved it.
1. Downgrade to 4.4.4 via Odin. Extract OC4, extract Odin, open Odin, select four files into correct position (BL, AP, CP, CSC) 4.4.4 OC4 Odin 3.09 (Samsung Mobile drivers required)
2. Once on 4.4.4 or below, enable developer options by tapping "build version" several times, enable USB debugging & mock location, and install KingRoot 4.0.0.233 to phone. Caution, newer versions did not work for me.
3. Open "Command Prompt" and type "adb version" should reply with "Android Debug Bridge version x.x.x", if does not, change to the correct directory where adb is installed via "cd" command. Need ADB? Here
4. These next two steps can be a little tricky as the phone often reboots before completed, must work quickly, I suggest copying the long command, then paste when ready.
5. Connect to working WiFi. Turn off your phone, reboot, or wait for it to reboot itself. Soon as phone turns on, open KingRoot, soon as WiFi connected notification appears, touch button in center of KingRoot app, soon as KingRoot reaches 30%, began adb commands.
6. ADB commands: first command "adb shell", second command "su", third command "dd if=/dev/zero of=/dev/block/mmcblk0p10 | dd if=/dev/zero of=/dev/block/mmcblk0p13 | dd if=/dev/zero of=/dev/block/mmcblk0p14 | dd if=/dev/zero of=/dev/block/mmcblk0p15 | dd if=/dev/zero of=/dev/block/mmcblk0p16" phone will reboot or you can reboot and after reboot boot-loop and unknown baseband will be fixed! Can now write new IMEI via "Write Cert" and possibly "Write QCN" if any network troubles, then all good to go!
7. Any questions feel free to contact me on skype: brandon.sisco or phone: 949.482.7058 I'm happy to walk you through any steps.
Once you see results, I have worked hard on this complete solution for many weeks, I would appreciate any donation. Secure paypal donate here

There's a possible fix until the moment you flash persist or restore EFS from another phone to yours.
ONCE AGAIN, DON'T TRY TO FLASH PERSIST OR RESTORE EFS FROM ANOTHER PHONE!!!
Just root your phone using Magisk and execute these commands using adb on your PC/laptop:
Things to note before you start executing commands below:
1. Make sure that USB debugging in your phone is turned on.
2. If everything is set properly and "adb devices" has been executed, u should see popup window about ADB allow on your phone BUT ONLY IN CASE YOU ARE USING ADB ON PC WHICH WASN'T USED FOR ADB YET. Make sure "Always allow from this PC" is checked and click "OK". Re-run command one more time. You should be able to see your device in cmd window now.
3. After "su" command, you have to grant root access to adb shell within 10 seconds.
4. "adb reboot" command will immediately reboot your phone, don't panic.
5. You are doing this at your own risk.
Code:
adb devices
adb shell
su
chown -R rfs:rfs /persist/rfs
chown -R rfs:rfs_shared /persist/hlos_rfs
adb reboot
Commands have been used from this thread: https://forum.xda-developers.com/g5-plus/how-to/fix-persist-resolve-imei0-explanation-t3825147
Good morning!
Look I was able to recover the signal (h +) with that command but not imei. Will not you know other commands that will make him recover or some method? regards
