[Q] Please help guys

I have installed 4.2.2 on nexus 7. As I had skipped account login at welcome screen, i could not login the account. I altered the apk of login. After factory reset my device has hanged on setup on welcome screen. I tried installing custom rom through stock bootloader but the bootloader says installation failed. How do I solve thia problem guys???

subin.nexus7 said:
don't know the exact steps, but i got it out of the APX mode and into the bootloader.
1. Tablet plugged into computer.
2. Held Volume Down + Volume Up + Power (simultatenously) for three seconds
3. And then released all, and pressed Power again.
4. Tablet booted into bootloader.
I thought that unlocking the bootloader ALWAYS voided the warranty, but in anycase I flashed reflashed ALL stock and locked the bootloader. Will be sending it to ASUS now. Thanks again!
EDIT:
So I wanted to verify that it was a CPU problem, and I downloaded StabilityTest again and ran the CPU load test. It crashed within two minutes, and went into AXP mode again. To get it out of AXP mode, the correct instructions:
1. Plug in the usb into computer
2. Hold Volume Down + Volume Up + Power simultaneously for like 15 seconds
3. The bootloader should show up.
4. If it doesn't, unplug the usb cable, and plug it back in and then repeat the these procedures.

Very helpful! I don't have a problem but I've read about others stuck in APX mode. This should be pinned if it works for those stuck in APX. Maybe you should change the thread title to something about APX solution so it draws some attention.

Well... being stuck in APX doesn't necessarily mean your hardbricked. (Corrupt or erased bootloader).
But being hardbricked DOES mean your device will default to APX mode.
To use a mathematical metaphor, one is a SUBSET of the other.

bftb0 has posted an exhaustive list of Nexus 7 button press combos here...
http://forum.xda-developers.com/showthread.php?t=2133986
... which includes how to pro-actively get into APX mode... although until somebody figures how to nvFlash the N7, APX is sort of redundant.

I'm sort of confused about the relationship between your edited post and what (apparently ?) kieso quoted, but I'll throw out a few suggestions:
1) AFAIK, there is no way to flash a dev ROM using fastboot (only the boot image of a dev ROM can be flashed this way). You said "bootloader", not "custom recovery" ... so that implies using fastboot. If that is not the case, then your use of terminology is not correct. (It's a computer - reporting details correctly is incredibly important).
2) If you bypass the WiFi login, an account can be added at any time later using the settings menu or simply by launching the Google Play (market) app - there is no need to "alter the apk of login", whatever that means.
3) I would recommend at this point that you start completely over by flashing a factory ROM using fastboot - see the sticky thread about returning to stock using fastboot. If you already have the 4.18 bootloader installed, I recommend you avoid like the plague any operation involving flashing the bootloader.
4) It should be obvious from the trouble that you got yourself into that you should learn what nandroid backups are and that you START USING THEM. The first thing you do after rooting is "make a backup", not "flash a ROM"
good luck

Thanq so much.But still some clarification needed
Now What do I do? My nexus 7 can't pass through at welcome screen saying saying unfortunately setup wizard has stopped. and in recovery{i have no custom recovery, I use bootloader 4.18} i cant flash any rom. I just want to start device any how.. any way.. Is there any way??

I guess I am having trouble understanding the sum total of information you have provided - I guess you have omitted some information or mis-stated something. No custom recovery sort of implies a full stock device, but yet you previously mentioned modifying/changing an .apk in /system... normally that would be possible only with a rooted ROM or a custom recovery to do that.
If your tablet is 100% stock, a factory reset of the tablet should allow you to boot once again - at the cost of deleting everything you put on the device, including all files you put on the (pseudo-) SD card.
If that is the case:
- press and hold power+vol-down until the bootloader screen shows up
- use vol-up/vol-down to select "start recovery" and press the power button
- an android lying on it's back should show up; this is the stock recovery splash screen, so
- press power+vol-up simultaneously for about one second - the stock recovery menu should show up
- select factory reset (with vol-up/vol-down) and press the power button.
good luck

when you say at the cost of deleting everything, does this include deleting everything in the bootloader because thats what I did when I used the command "fastboot erase bootloader"

Brah its so easy to unlock oem!
I'm so shocked and surprised that you guys haven't figured out how to unlock bootloader. Aren't you guys like the smartest computer wizards alive? Anywho... Ok kid this is how you unlock oem and will allow you to install any os you want.
Step one: power off your phone.
Step two: when you power off your phone and at the moment that your screen turns black press down and hold:
Step 3: Press both volume buttons at the same time, then after you feel the phone vibrate one time immediately...
"without lifting your fingers off of the two volume buttons"​ press and hold the power button.
Step 4: As you continue to hold down all three buttons at the same time.
The phone will vibrate, then it will take you to a green screen that states that installing a new operating system will erase your data, or void your warranty, or something like that.
Step 5: press the Volume Up Key to accept the consequences.
When you restart the phone will download an update which will allow oem unlock option to appear in Developer Mode Options.
Step 6
Go to about phone, then scroll down to Software Information, then click on Build Number 7 times. Go back to Settings and scroll all the way to the bottom and access developer options. Then scroll down until you see oem unlock. Check for notification of the update finishing.
Do all of this by the way with the phone connected to your computer. There's like a couple of tutorials online that you can find on youtube and on Library.
TADA! It worked for me just fine; ya sheee?!

What you have done does NOT root the phone
You obviously have not read this section.
The 205U cannot be rooted
You can only install official updates
look here
https://forum.xda-developers.com/galaxy-a20/how-to/android-10-q-guide-a20-t4095589

Disregarding official methods of rooting your phone, is there any way of manually or forcibly patching or modifying the bootloader without permissions given by the manufacturer? Such as doing so by an outside terminal on a computer.
I understand the risks of bricking a phone device.

It's a 50/50 chance for rooting. Samsung may remove the rmm lock on the a20 series once our 2 year update period is over.
Or it may be like the Verizon samsung galaxy S4 which has still never been fully rooted.

[Guide] How to root N20

How to root N20 (N985F/N986B/N9860)
WARNING!
Before you root your device you must be aware that
This will void warranty.
As of now you will lose Samsung Pay and Samsung Pass forever if you root once, even unrooting won't help.
There are many features stop working when you unlock bootloader other than S pay/Pass like Samsung Health, Secure Folder, Galaxy Watch pairing issue, Issue connecting old gear watch (S3 or earlier), Google Pay etc but some ROMs are patched for all these mentioned features, you can use custom ROM or patch it yourself for stock ROM. Still you may trouble using some bank apps and these may fixed by adding these apps to Magisk Hide
There may be some knox features there which you may not able to use but I can't list those as I never used. Just Google It
Patched featurs are working today when writing this, No idea if it may stop working next moment/tomorrow or later
Also to note, once you root, you can't go back to "pre-rooted" state completely. It is one way!
OTA won't work once you root device.
ROOT with caution.
You can unroot & Relock bootloader after flashing stock firmware, but still your warranty flag remain 0x1 and most of countries it still voids warranty. Also after unrooting & relocking bootloader, some knox features never work again.
How to Unlock Bootloader
Follow below four steps to ulock the bootloader
1.Enable Developer Option
Open the Settings app on your Galaxy device.
Choose About > Software Information.
Now tap on Build Number 7 times to enable the developer option.
You’ll get a message “You’re now a developer.”
Now Developer option has been enabled.
2: Enable OEM Unlock
Go to the Settings app again on your device.
Navigate to the Developer option.
Enable the toggle next to OEM Unlocking.
Tap YES to turn on the confirmation dialog box.
3: Boot Your device to Download Mode
While device is booted → Connect device to PC → Select to Restart → As soon as device screen turns off, Press and hold Volume Up + Volume Down simultaneously OR In case device is powered off Press and hold Volume Up + Volume Down simultaneously and connect your device to the PC via a USB Cable.
You can see the warning message on your device and release the pressed keys.
Finally, press the Volume Up key once, and you will be booted into Download Mode.
4: Unlock Bootloader
Once device booted into Download Mode, you will see option to long press Volume up to unlock bootloader,Now, press and hold the Volume Up key for a few seconds., Here, you’ll get a confirmation whether you are sure to proceed.
Use the Volume Up button to reply to the confirmation.
This will erase all the data on your device and unlock the bootloader.
Once completed, your device will automatically boot up to the OS.
Now you have successfully unlocked the bootloader
How to root
Instructions for stock non rooted ROM​
Use either samfirm.js, Frija, or Samloader to download the latest firmware zip of your device directly from Samsung servers.
Unzip the firmware and copy the AP tar file to your device. It is normally named as AP_[device_model_sw_ver].tar.md5
Install Magisk apk
Press the Install button in the Magisk card
Choose “Select and Patch a File” in method, and select the AP tar file
When done, copy patched file to PC
Reboot to download mode. Open Odin on your PC, and flash magisk_patched.tar as AP, together with BL, CP, and CSC (NOT HOME_CSC because we want to wipe data) from the original firmware.
Your device should reboot automatically once Odin finished flashing. Agree to do a factory reset if asked.
Install the Magisk app you’ve already downloaded above and launch the app. It should show a dialog asking for additional setup.
Let the app do its job and automatically reboot the device. Voila!
Upgrading the OS​Once you have rooted your Samsung device, you can no longer upgrade your Android OS through OTA. To upgrade your device’s OS, you have to manually download the new firmware zip file and go through the same AP patching process written in the previous section. The only difference here is in the Odin flashing step: do NOT use the CSC tar, but instead use the HOME_CSC tar as we are performing an upgrade, not the initial install.
Important Notes​
Never, ever try to restore either boot, recovery, or vbmeta partitions back to stock! You can brick your device by doing so, and the only way to recover from this is to do a full Odin restore with data wipe.
To upgrade your device with a new firmware, NEVER directly use the stock AP tar file with reasons mentioned above. Always patch AP in the Magisk app and use that instead.
Never just flash only AP, or else Odin may shrink your /data filesystem size. Flash AP + BL + CP + HOME_CSC when upgrading.
PS : It is strongly recommended to make EFS backup once you root device and save to safer place like on cloud or PC

Once you have enable OEM unlock option, switch off your device and reboot to download mode.
To put device in download mode - Press Volume Up & then Press Volume Down (Keep holding both) and connect device to PC with USB cable
When device start to download mode,long press volume up to unlock the bootloader. This will wipe your data and automatically reboot
Now let finish setup and again enable developer options (as said above), and confirm that the OEM unlocking option exists and grayed out!
If it is not then you can not root device!

What I guess, here unlocked means sim unlocked NOT bootloader.

Some people might need clarification. An "unlocked" phone is not the same as a phone with an unlockable bootloader. If it's the same pattern from the past several years of Note releases. All of the snapdragon US versions won't have the ability to have their boot loaders unlocked, therefore a root. This root method most likely applies to the non-US Exynos versions. If you live in the US, and ordered your phone through Samsung or any carrier, it will be the snapdragon version. I hope I'm proven wrong.

Plz post your question to appropriate forum

no one has the S pen pointer option?
Also have any of you signed up for beta 3.0 android 11 for the s20? Im guessing you guys have early access because the note 20 isnt even out yet.

"Error updating for slotselect" in Recovery mode on Samsung Galaxy A73 5G

I want to boot the phone to bootloader mode. However, when I come to the recovery mode, it says "[libfs_mgr]Error updating for slotselect" at the very bottom of the screen.
If I continue to choose Reboot to bootloader, it prints the same error message again a second time, and very quickly (less than 1s) reboots to the OS. So I can't go to the bootloader.
If anyone knows what happen and how to fix it, please help. Many thanks.

I have the same problem on the SM-A528B and any rom that installs even the originals with the bootloader locked to the original settings, still, my tele keeps blinking as if it had superimposed images... If anyone has a backup of the ROM STOCK, obviously without the data and EFS and can make it available I would appreciate it, I think it's some partition error, but so far I haven't been able to find any tutorial to clean and reinstall from scratch...

Imma need a bit of assistance here. I have been trying to get into Download (DL) mode while pressing vol up + down and plugging in the cable. But it just starts charging.
I can get into DL mode through recovery but that goesn't give me an option to unlock bootloader. Of course, OEM unlock and USB debugging are turned on. I even flashed the latest firmware A205FXXSBCVI2.
I was trying to odin flash custom recovery image which doesn't complete and on DL screen it says, Custom image (boot) blocked by OEM lock. I have unlocked a lot of phones before but I guess I never had to unlock a Samsung bootloader!
Thanks in advance.

This should work:
The following steps WILL WIPE YOUR DEVICE
1. Enable Developer Options by pressing the “Build Number” option in the “Settings” app within the “About” menu
From within the Developer options menu, enable OEM unlock.
3. Power off the device, and boot it into download mode:
With the device powered off, hold Volume Up + Volume Down and connect USB cable to PC.
Now, hold down the “Volume Up” button until you see the “Unlock bootloader” screen.
Then press the “Volume Up” button once to unlock the bootloader.
7. Your device will reboot twice and erase your data, you may now unplug the USB cable from your device.
8. Run through Android Setup skipping everything you can.
9. Re-enable Development settings by clicking the “Build Number” option 7 times, in the “Settings” app within the
“About” menu, and verify that “OEM Unlock” is enabled and greyed out in the “Developer options” menu.
If you have any problems, let me know.

I'm having the same issue did you got it to work

Nope. I don't have access to that phone for the time being. But I came accross a point that we need to plug in the audio cable on new Samsung phones to get that unlock option.
Haven't tried yet though.

Is “OEM Unlock” greyed out?

Nope. I had it enabled.
