My bro accidentally clicked on OTA upgrade. I have bootloader unlocked , rooted P765 with cwm 6.0.2. I searched this forum for solutions and got some.Unfortunately none worked for me.
http://forum.xda-developers.com/showthread.php?t=2247371 - this method did not work . my phone also has some issues with USB i guess. Everytime i connect to pc , i get device not detected error. screes attached.
http://forum.xda-developers.com/showpost.php?p=40423549&postcount=2 ----this did not work. same as above.
i also tried with exitrecovery.zip . It ran successfully from CWM but everytime i boot, phone still goes to CWM recovery mode.
exitrecovery has following code
busybox echo -ne "\066" | busybox dd bs=1 seek=4107 count=1 conv=notrunc of=/dev/block/mmcblk0p8
I did trial and error with mmcblk0p till 1-20 with no success.
Here comes the saddest part...I also went to LG service centre. He also couldn't help.That guy told me motherboard is dead due to rooting.
I am sure that my p765 is very much alive.
I can go to Software upgrade mode on my phone, but my pc doesnt recognize it. I have latest LG drivers installed on my system.
NOw i think only way out of this could be a script to flash from CWM. Please help me!!.
I tried flashing other roms like Superlumina,Avatar. Also tried Ubuntu touch with no success. Still goes to CWM.
I am on JB India V20A.
Thanks in advance.
screen of device not detected. I have LGUnitedMobileDriver_S50MAN310AP22_ML_WHQL_Ver_3.10.1 on my system.

Try to disable your LG drivers and do the flash again via S/W Upgrade mode. . .I want to see if that will work. Let me know.

Darn! Sorry brother, looks like you are going to have to go the LONG way around. ICS u-boot and x-loader worked for me.

:crying: any scripts like exitrecovery to flash?? dying here seeing the state of my phone!
edit
You need to install fastboot drivers: http://forum.xda-developers.com/show....php?t=2119090
Turn off the phone and remove the battery. Download THIS and exctract it to C:/. Open device manager in windows (Rigt click on Computer > Manage > Device manager) and connect your phone without the battery to pc via USB cable.
'This' link is broken... u have the files brother?
SOLVED
I connected my phone in Software upgrade mode. Same error pop up- USB device not recognised.
Selected 'Options' from LG User support tool and clicked 'Update recovery'. Entered my mobiles serial number.
AFter around 3 hours of download, my device is detected on my system!!! I seriously did not do anything on my system.
AFter the download was complete, the update was installed. My P765 is BACK!!!!

I'm a new member to this forum. Need your help.
My P765 got stuck up with CWM recovery after an OTA update. I flashed some custom rom's but still it does end up in CWM recovery only.
Could you please upload the CWM zip to flash the stock recovery. So that I can get to back to my P765.
I have been searching in all the forum. Finally found this to get solution. Thanks in advance

The following will work with all OTA boot loops to recovery. The guide is for p765 but it will work with all variants. If you flashed a custom ROM trying to fix the problem, please restore your stock rom backup. Also, if you still have artas182x locked bootloader recovery (or you removed any system apps), the update will fail, but you will be of the loop
what kdz are you currently on? I made the zip but i need the extracted p765 recovery.img.
If you have the kdz please extract the recovery.img (look at my signature on how to extract it).
i could give you the p760 20b recovery.img but I think it would be best to use the recovery.img of the current kdz you are on (to be on the safe side).
Note: if this doesn't work, you will need to use the unoffical fastboot. So you might want to get fastboot setup before trying this. Actually, you probably won't need fastboot, but you will need to restore your custom recovery.
Or use the longer method (takes more time, depends on your download speed), LG mobile support tool.
Once you get the stock recovery.img for your kdz, Open the p765_stock_recovery.zip and copy the 3-recovery.img into the zip file.
Note: Don't change the name of the recovery.img or it will not work
The recovery must be named 3-recovery.img
Place it on you sdcard and flash with cwm and reboot.
Or sideload into your phone with cwm and your computer
Code:
adb sideload p765_stock_recovery.zip

i was follow this step, but still error
my device still black screen, cant power on
Hello everyone,
first of all im a total beginner on this field and it's the first time doing this stuff.
since there are no updates further than 4.2 for the beautiful HOX+ i tried to flash the cyanogenmod11 rom on my device. i used hasoons all-in-one toolkit. i followed the guide step by step and got stuck now in a hopefully not that serious problem.
i unlocked bootloader and flashed the cwm international recovery. the recovery was working fine and i did a backup. then i flashed the kernel with the boot.img from the cyanogenmod11.zip and the problems started. when normally booted the phone lights up with the white htc screen and then turns off again after about 3 seconds. i haven't flashed the CM11.zip yet and i guess that was the mistake? i still can acces the recover as well as the bootloader but like already said the phone doesn't start. another problem is that adb doesn't find the device enymore and only prints an empty line when using "adb devices" howevery using "fastboot devices" still gives me the proper result. hasoons toolkit also doesn't recognice the phone anymore.
if anyone could help either getting back to a custom rom or preferably setting up cyanogenmod properly would make me really happy =).
i hope this is the right place for this. i also searched around for hours and hours but can't find anything that helps me.

so you have installed the kernel but not the rom? if so, then you need to flash the rom and then it should work

you normally flash the zip via recovery, do you already have the zip on your phone?
if so, go into recovery and install, find the zip file and install it
if you don't have the zip on your phone then you will need to sideload the zip to your phone, (fancy way of copying the file to your phone) then post 4 tells you how to sideload the rom: http://forum.xda-developers.com/showthread.php?t=2066390

the problem with this is that i first don't have the zip on my phone so cant install from the recovery and second that adb doesnt recognize my phone for whatever reasone so i can't sideload the rom. if anyone experienced similar problems (fastboot working, adb not) please let me know how to fix it
Lukas
another thing i just read about is the possibility if one already has installed a running cyanogenmod rom on his device he can extract that as an system.img if i remember right and i could use it on my hox+. just in case anyone knows how to pull that off let me know =)
otherwise still looking for hints how to install rom via fastboot or how to make adb working again

Try flashing the ROM onto the phones storage. Then you can install the ROM. If you cant even charge your phone then you have bigger problems than not having an OS installed.

Hey guys,
I've had a total of 4 android smartphones during the last years, and I did root all of them and even install diferent ROM's, but on this phone (Honor 7) was kinda diferent.
The root process is way more complex than all the other androids I did root (simply flash a .zip file...) so I've been post-poning this task over and over..
Finally yesterday I gained courage to try out rooting my phone, and while attempting to root my Honor 7, after flashing SuperSU from TWRP, my phone no longer booted.
Stressed as I was, I just told to myself "f*ck it" and formatted the system and I didn't care much if there was a fix without needing to format the system. (but then I realised that I could not find any .img ROM files to flash from TWRP recovery, so basically I did my actions wrong once again)
I followed the tutorial from guidebeats.com which talks about rooting EMUI 4.0 Android 6.0 (I cant post links)
Basically this is the story:
While unlocking the bootloader, even though, the tutorial said the phone would reboot itself after typing "flashboot oem unlock 1234934829" I did a hard reboot (or reset?) holding (VOL+) + Power button and I have the feeling that the bootloader unlock was not 100% done, even if it said it was unlocked. (Phone was working perfectly fine there)
Then I flashed SuperSU, and I could no longer boot. After powering up my phone, after the first splashscreen, the screen would only turn black.
What (I think) I need to now is remove the TWRP recovery, and use the stock one and attempt to install an "update" using (Vol+) + (Vol-) + Power. (please correct me if I'm wrong)
But now there's some issues I got that I'd like some help with:
1- How can I get back to the stock recovery? (NOTE: I currently got no OS installed on my Honor 7, since I formated it)
2- Will I need to lock and unlock my bootloader again (if I want to 'fix' the bootloader unlock?)
3- Where can I get official Honor 7 stock ROM? (would be awesome if there was already the Android 6 stock rom for a clean install)
4- What are the steps on this tool (Honor 7 Multi-Tool) to root my phone?
I need my Honor 7 asap
Sorry for the long post, It's my first time doing a more advanced root and I have all these questions.
Thank you very much for any kind help!

As you are already familiar with adb and other stuff so will write a short post for you.
To download latest firmware, head to
http://forum.xda-developers.com/hon...tock-firmware-packages-honor-7-t3448747/page1
Google, download and install Huawei update extractor and open UPDATE.APP in it (obtained after extracting firmware).
You can see all the images. Just extract recovery and boot to platform-tools folder.
Meantime, do the unlocking command again, with
Fastboot OEM unlock xxxxxxxxxxxxxxxx
Followed by fastboot reboot
And press and hold the vol down button again until you reboot in bootloader.
Flash the recovery and boot you extracted using
Fastboot flash recovery recovery.img
Fastboot flash boot boot.img
(I got a habit of extracting and flashing system and Cust using
Fastboot flash system system.img
Fastboot flash Cust Cust.img
But they are not necessary)
Now you are set to try a 3 button update (sometimes it gets stuck so if it's stuck for 15 minutes, try 3 button again).
Please do report back if it comes to life.
To root, just flash twrp and then use SuperSU 2.62 (no other version) and update it later using play store.

Hey!
Thank you alot for your reply.
From the link you sent about the firmwares, there are alot of Builds for the L01 (EU) model. Can I simply use the latest from the list or I gotta install 1 by 1 (from older to newer)?
Also, the bootloader unlock thing, is it ok if I wait to do it until I install the stock ROM again? Because I think I don't have the code anymore (Also don't know about IMEI)
Other thing, yesterday before bricking my phone, I tried to re-unlock the bootloader as you said above, but it didnt let me because "it was already unlocked".
I really have no idea if it's 100% unlocked or not.
important thing!
With those ROM's, I still have the right to receive official OTA updates from the HiCare app right?
Thank you again

Just use B380 as it's the latest full firmware available there.
Unlocking bootloader again was just a precautionary measure (proceed without it and if it is not 100% unlocked and if something goes wrong, we can troubleshoot later, which imo, won't happen)
And yep, if you keep the firmware as it is, but if you flash twrp and root, you will still see the update available in Hicare but will have to install stock recovery again before upgrading. (Nothing else is needed as SuperSU 2.62 gives a systemless root so you only need to flash back stock recovery for an update)
I am not against honor-tool bit it's best to do things manually as it makes you learn stuff and is easy to troubleshoot if something is amiss.

Alright, btw, about the thing you said
"Now you are set to try a 3 button update (sometimes it gets stuck so if it's stuck for 15 minutes, try 3 button again)."
I gotta do that myself with an "update.app" file or what?
Sorry, I missed that part

You have to make a dload folder in SD card and copy UPDATE.APP to that folder.
Then just turn off the phone, press and hold power + vol up + vol down until phone boots.
Let go of power but keep others two pressed for 5, 6 sec more. Your phone will boot into recovery and start installing UPDATE.APP
It likes to get stuck at 5% (most reports) but sometimes, somewhere else. If its stuck for 15 minutes on a particular percentage, just press and hold the above three buttons again using the same process.
Multiple tries make it work...

Hello
How did you format your phone?
I'm still struggling with going back to Android 5 and EMUI 3.1 since there is no rollback file available. (PLK-AL10, B396) Maybe formatting and installing the old rom could be a solution, like in your case?

Hello.
Do you have unlocked bootloader and TWRP recovery? You can format your phone from TWRP recovery.
I think the only option for you is to get the old ROM img and flash it (starting from 0)
You can dirty-flash (Flash a different ROM with same android version as yours, e.g: flashing custom android 5 ROM over your stock android 5 ROM without factory resetting your phone) but I dont think you can do that from Android 6 to 5.

Yes I have unlocked bootloader and currently not twrp but I can flash it at any time.
The last two paragraphs you wrote are different solutions or the last one is a more detailed explanation of the previous?
I have android 6 so the later method won't work as you said.
But formatting it and flashing a stock android 5 rom - is it that simple? Nobody here suggested this before, however I have been asking for months.
All the phones are empty when they leave the assembly line.
How did you flash the new rom to your formatted phone? Extracted update.app and flashed each file with fastboot? Any issues you faced?

From my last 2 paragraphs, the first was a solution, the second was an impossible alternative that I thought it would work.
My issue was that I had a custom recovery but I had no ROM installed, so I had to install the stock recovery and boot (extracting from update.app) and flashing it via fastboot, to afterwards force the update with 3-button method.
-----
What you'll need to do is:
- Flash TWRP
- Wype system, data, cache.. (so that you completely delete your current ROM)
- Extract recovery.img and boot.img from an update.app of an Android 5 ROM you'd like to have (Official ROM for your device model)
- Flash them via fastboot (You'll go back to stock recovery again)
- Shutdown your device
- Create a folder named "dload" on your sdcard and put UPDATE.APP file in it.
- Reboot
- Do the 3-Button update ([Vol+] + [Vol-] + Power)
- If it works, it will auto install
(- If it gets stuck on 5% for over 5/10min, force reboot pressing [Vol+] + Power) and try again the installation
- After installing it will boot normally (first boot takes a while)
NOTE: I'd recommend creading the dload folder before wiping the ROM, because usb didnt work for me afterwards. (It would still work if I was on recovery tho)
>> Remember to make a full system backup before wiping aswell, dont be stupid like me xD (thats why I had to full wipe my system after soft-brick)
Im answering based on what I did and was explained here to me

Hi again,
I'm doing this OS installation now. It starts fine but stucks at 90%, (I'm trying to install the latest stock ROM which can be downloaded from Huawei site, B220 or221). Did you have the same issue? I waited more than half an hour at 90% but did not go on.

Hello
How did you format your phone?
I'm still struggling with going back to Android 5 and EMUI 3.1 since there is no rollback file available. (PLK-AL10, B396) Maybe formatting and installing the old rom could be a solution, like in your case?
Click to expand...
Click to collapse
Maybe formatting, Flash stock Android 5 recovery using Honor multitool , and then Flash a Android 5 firmware
Not sure it Will Work without rollback..
Finally, after 2 months of struggling I managed to get back to Android 5 and EMUI 3.1 without a rollback file.
Here is what I did:
0. Download a full ROM you want to install
1. Backup of the current system with Hisuite (everything. Apps, media, contacts, call log, etc.)
2. Flash TWRP recovery with fastboot (start phone in fastboot mode)
3. Wipe (and format!) everything you can with TWRP
4. Extract boot.img and recovery.img from update.app of the new ROM with Huawei Update Extractor
5. Flash boot.img and recovery.img with fastboot.
6. Copy update app to dload folder on SD card, insert into the phone.
7. Restart phone with [VOL+] + [VOL-] + [Power] buttons to force update.
8. The system will be installed from SD card. I had no issues with the installation. First I did not format the phone (just wiped) and it did not work.
9. Restore data from backup.
The only strange thing is that the native app icons look different than my previous lollipop system. Don't know why. They are less colorful. I installed C00B220 for PLK-AL10.

Yes it does. (It did for me.) Technically this is not a rollback but installing a brand new system on an empty phone. That's why it is important to do a backup upfront.

Thanks for the answer. Im gonna try this method. I can't reflash any region rom.
Hello XDA!
I am writing this thread to ask for help rooting my Samsung Galaxy J2 Pro.
I attempted to use apps such as: Framaroot, Kingroot, etc.. but so far none of them have worked and I have not been able to find a working guide on the internet of how to root my phone.
I also tried installing an unofficial version of TWRP for my phone but everytime I tried to boot into the recovery it would say "No Command" and then boot into the original recovery.
Is anyone able to help me root my phone? Can it even be done?
Any help is sincerely appreciated. Thanks!
Phone Specifications:
Samsung Galaxy J2 Pro.

Try this at your own risk
Make a backup before trying
I got root access with this method
Download stock Rom from sammobile extract and there should be 5 MD5 files extract the AP file with 7z and copied boot.img on to sdcard
Installed MagicalMmanager-7 used it to patch the boot.img to a tar file
Copied the boot image to my pc desktop then flashed the boot with odin
When I booted it back up magisk manager kept crashing so I uninstalled it and installed magiskmanager-5.23 rebooted it opened magisk and followed the prompts to update it

Hello there.
I have tried to patch my boot.img but when I put into a .tar and flash it, it doesn't flash, it's just stuck on file analysis despite being able to flash other files. Would you be able to send me a copy of your boot.img, thanks.
Kindest Regards

Unfortunately I have not found a solution. Please notify me if you find one.
here is a copy of my boot.img after flashing this you will get a verification problem and you will have to reset your phone if it bootloops into recovery or starts to update and says no command take battery out put it back in and boot it again or boot in to odin mode and push down and boot it eventually it will boot in to recovery then factory reset it. first boot may take 5-10 minutes
my software version is J250GDXU2ARD3_J250GXSA2ARD3_XSA

Hello and thanks a lot! I flashed my boot image and now when it boots it says "Set Warranty Bit : Kernel" and an infinite booting screen.
What do I do from here? or do I need to flash the original rom?

Hey, sorry for the late response. Everything is working fine! I now have superuser abilities but everytime I try to flash my recovery with TWRP it just loads the stock recovery. I even tried removing certain files from the root folder to avoid the stock recovery being flashed but it hasn't worked.
Any idea? Ps. You are a life saver my man.

glad i could help and i don't think there is an official twrp for this device here is one i ported a couple things still don't work mtp and sideload but it's not really usable until someone ports a rom due to the data encryption which you have to format to be able to flash anything

Hello,
Sorry, I don't have the J250G anymore as I traded it for a J5.
Kindest Regards
Jayden
My internal storage showed I only have 8gb instead of 16gb. Is there a fix for this?
P.S. Wiping data fixes it
ok
You can extract it from the AP file from stock firmware using 7z
hey
hey everyone im just wondering but is there a kernel for this device yet or any rom ("J250G")
Is there any way to work root for galaxy a10s i tried all the methods and didn't work with me ... even the boot.img method via odin didn't work with me .... is there any other way ?????
Galaxy a10s Mediatek MT6762 Helio P22 (12 nm)
CPU Octa-core 2.0 GHz Cortex-A53
Any helps please
Good morming,
This link worked for me: https://www.full-repair-firmware.com/2019/10/how-to-root-a107m-9.0.html
Although I didn't use the BL from the (in my case TELCEL SM-A107M) firmware, I downloaded this Boot file (I don't remember from where ), it is for A107MUBU3ASI4:
https://mega.nz/#!tRgXgCTI!dHdQPB-MSQ7Znpm7d-Nme7lwwc_w2-im75putNHxgtM
SO I copied the boot file to the sdcard, ran magisk manager on the phone, selected patch boot image and selected the boot image on the sdcard for patching, after the patching is done, I copied the image back to the PC, started Odin, booted the phone to download mode (turn it off, connect the phone to the usb cable press power button to start the phone, then release the power button and press both volume buttons until it boots to download mode), then when Odin detected the phone I clicked the AP button on Odin, selected the patched boot file that I copied from the phone and then clicked on the Start button to flash the image, then when Odin finished, the phone booted automatically ... the tutorial says that the phone will ask for a factory reset and delete all the phone info, but in my case it didn't asked for nothing nor deleted my data, so I got root without losing information, as soon as the phone booted it was already rooted an root was working witout me having to do anything.
The first time I rooted my phone I installed xposed framework, then had some troubles with the beta version, got a bootloop and had to re-flash the original firmware, BUT when I tried to reflash the patched boot image I got the PreNormal message and had to wait a week to root again my phone .
So I googled and then found some info about the KG/RMM problem, but couldn't find a zip that worked for the SM-A107M, also since there is no TWRP available to this model, I wouldn't be able to flash the zip anyway, but I found that deleting this files:
libvkjni.so
libvkmanager.so
libvkservice.so
KnoxGuard.apk/Rlc.apk
will disable the service.
The first 3 are in the system/lib directory, the knoxGuard apk is in the priv-app/knoxGuard directory.
So I rooted the phone again (after waiting 7 day to prenormal to end) and in the first boot I
installed "Root Explorer" from the play store (Any file manager with root privileges will work) and deleted 4 of those files (the RLC.apk I couldn't find) and after 2 weeks of rebooting, reinstalling xposed, getting the bootloop problem again , re-flashing original firmware (without the KG/RMM prenormal state), re-rooting, and finally installing xposed without problems (in my phone the 4.6.0 beta version didn't work so I inistalled the 4.5.1 beta) I am happy with my rooted, xposed phone.
I would really like if somebody created/xported a TWRP for this model, but in the interim all is good the ends good.
Regards
:good: Thanks for the wonderful information .... But the problem I have is KGG / RM PRENORMAL STATE .... must do cancellation of the first ...
If you have already Prenormal state, then you have to wait 7 days, dont turn off your phone, don't restart and don't disconnect from the internet, then after the 7 days (168 hrs) the prenormal state should disappear!
Check this link:
https://forum.xda-developers.com/sa...w-to/guide-root-install-twrp-samsung-t3747535
Best Regards
I did not find prenormal state or normal.....
I found : KG status : checking
OEM unlock : off
Then, if not in prenormal, you should be able to flash and root your phone!

Good night
Unfortunately .... this root method did not work for me .... via Magisk ... I don't know what the problem is .... but this method did not work for me which is in many websites and it is the same way .... As follows my device info :
Ap: A107FXXU3ASJ5
CP: A107FXXU3ASJ1
CSC: A107FOJM3ASJ5
Model: sm- A107F / DS
The same method is used by everyone via Magisk ...
My device have no problem:
Unlocking the device bootloader
OEM unlock: off
Kg status: checking
I have no prenormal state
I followed all the steps on the sites
1- I downloaded Galaxy A10S Firmware
2- I downloaded and installed the latest Magisk Manager app.
3- Copied only the boot.img file from the extracted folder to a device storage.
4- opened the Magisk Manager app then clicked on on “Patch Boot Image File”.
5- when patched boot img finished from Magisk .... I renamed to boot.img and used 7zip and archived it to .tar format ....
6- I flashed via Odin in download mode but I got on fail .....
I don't know what problem ...
But this is what happened !!!!
Did you use the boot image (BL) I posted on the second post??
Download the file, copy it to your phone, use magisk manager to patch it, copy patched image to pc, flash via Odin to your phone.
Regards
No, I didn't use that boot img .... It the same : A107F .... A107M.. ???
I will try later.
I used that boot in your post .... for A107m.... l flashed via Odin in my A107F ... It's flashed in my device.... but when I boot to Magisk..... no root........ for that I think will wait someone to create twrp for galaxy A10s then I flash root.... Thanks for everything....
anybody with A107F firmware pls. i need to try to root mine.

What do i need to do to make the oem unlock option appear again?
I've already tried the turning off updates and changing dates thing.
And I waited out the 7 days ( Which was difficult since my IP doesnt have a stable connection.)
I've started doubting if it even exists at all.
I only got my A10s for free from a carrier plan.
KG Status is Normal
OEM is still locked and nowhere to be seen

If you made all the attempts and didn't succeed with you ... Install the stock firmware for your country ... and you delay the date a few months earlier ... then go to update the program .... then you should have an OEM unlock

And how does one Install a "different/new" firmware?
I remember doing it once or twice with Odin with a firmware I got from sammobile SMA-107f.
Succeeded. Although I don't know if it actually worked, since it booted up just like the first time I got it, with the carriers default wallpaper and pre-loaded apps.
I've been trying to root the SM-A107F for weeks now but no luck.. Any help will be appreciated

This is very interesting. KG State has been non existent on my device, I can flash modified firmware since day 1. I'll try this, I tried patching the whole AP_ file and there are problems with the signal, I did not try only patching the boot.img
Thanks!

when you flash the patched AP.tar you should also be flashing it with the rest of the firmware.. tjw even says somewhere on his github you shouldnt flash the patched AP by itself
