Hi There. My name is Giselle. I wanted to ask you if you can help me with issues and on advice is for me to do at this point. I had this phone with me 2 years + and I did a CF auto root file 5 months ago and I manage to do factory resets, wipe data even I downloaded Super SU App which disabled Knox the first time then I did it. Again it completely unrooted my phone even tried to see if rooting would be able to remove the file from my phone. When I Checked my recovery mode it still sees the file as tlecan but a different software number that was software updated when I reset it to new again.
On my Odin mode this is what it reads: CURRENT BINARY: Samsung Official SYSTEM STATUS: Official REACTIVATION LOCK: OFF KNOX WARRANTY VOID: 0X1 (1) QUALCOMM SECUREBOOT: ENABLE (CSB) AP SWAREV: S1, T1, R1, A1, P1 SECURE DOWNLOAD: ENABLE UDC START.
My updates on my Play store are slow. I even formatted my SD card to see if it was the issue but my phone still keeps acting in like a small twitched motion. it also sometime gave me an error code 142 on my updates. It did a new up to software date recently but would it be safe for my privacy? What do you suggest to all this?
I tried contacting other people but no one hasn’t respond to me. I hope this isn’t much stressful for you to answering me. Please e-mail me back. I appreciate it. Thank you and have a good day. — Giselle
Solution: Hi Giselle. There are a number of ways to unroot a device. Let’s discuss some of them.
- Unroot with help of an app. This is the simplest way to remove root access from a device. The thing is, not every app that can remove root access work on every Android device so you must do some research on what app you can use. A good app to start with is Universal Unroot. You can install it from the Play Store.
- Use SuperSU to unroot. We know you’ve already tried this step but for the sake of other readers, we think it’s worth mentioning, especially that’s it’s a popular tool.
- nroot by using a file manager.
- Install ES File Explorer app on your device. Don’t move it to SD card.
- Open the app and tap the menu button.
- Now tap on ‘Tools’ and select ‘Root Explorer’ to turn it on.
- Superuser will ask you to grant privilege or root privileges to the app. Allow it.
- Now go back to the main screen of the app and select ‘/’ in the top corner of the screen.
- Go to system -> bin. Find the busybox and su file and delete them. If you can’t find any of them, just skip to the next step.
- Go back to system folder then open ‘xbin’ folder and delete the busybox and su file there (if you found any).
- Now go back to the system folder again and open ‘app’ folder and then delete the supeuser.apk file located in the folder. That’s all.
- Now restart your device and it should be unrooted.
- Remove root by installing OTA update.Installing a system update from your carrier can sometimes automatically remove root access. If you’re lucky and there’s a pending OTA update, make sure to install it to easily remove root access.
- Manually flash stock firmware to remove root. If possible consider flashing stock firmware on your device via the Samsung Smart Switch app. This of course depends whether or not Smart Switch will be able detect your phone and install the needed update. If Smart Switch won’t work, you have to manually flash stock firmware via Odin mode.
Don’t skip system updates
Software updates contain a number of things including security patches, under-the-hood improvement, cosmetic changes, or fixes for known bugs. Installing software updates is a good way to keep everything up-to-date so we don’t see your point of questioning whether it will compromise your privacy or not. As far as privacy is concerned, only your carrier (or not) can give a direct answer for that. In general though, software updates are necessary to minimize bugs and problems.
I just got my AT&T S5 but it took a firmware update from UCUGOK2 TO UCSGOK3 . I rooted (KingRoot) the phone after update and replaced the KingRoot with SuperSU and then started to debloat the phone. All was good till a week ago and when I go to Web and try typing it lags badly. I can type 3-4 words and wait and then they finally show up. I’m using Samsung keyboard.
Also it has low microphone when I get phone call people say that they can barely hear me. Also lags when I make phone call it takes 10-15 seconds to let me speak. And for the next issue it has mobile data connect problem it says no network found , I close and open Internet couple times and sometimes it connects and sometimes it doesn’t . I’ll stop here with those issues . I do reboot and have taken battery out and Sim & SD card it locked up other day so I did a safe mood and it cleared up. Maybe I could find a way to reset phone without losing root, I don’t really want to reroot . Thanks I hope you can give me some info, just wish I could have rooted before B/L got lock so I could have TWRP RECOVERY. — Mike
Solution: Hi Mike. We suggest that you find help from forums where there are active users using the same firmware and root software running on your phone. Some unofficial firmware can be buggy and may not be properly evaluated with all Samsung devices. The general rule when it comes to a situation like this is to let the developer know about the problems so they can take a look at it. The good thing with custom firmware is the fact that they are developed by Android users themselves and they are usually active in forums. Try to post your problems in some forums to let others know of your problem. If you’re lucky, the community may help you fix it. Otherwise, contact the developer of software and ask for direct assistance.
Hey its Ashley. So I was playing a game on my phone and then it crashed. I have removed the battery trying to see if it helped and it didn’t help. My phone won’t even go the Samsung logo. I could really use some help. I have tried to restart but it just goes straight to a screen that says the follow: boot recovery mode Check boot partitions. Sbl1 partition does not work Odin mood high speed Product name: sm g901f Current binary: Samsung official System status: custom Reactivation lock: off Knox warranty void: 0x0 Qualcomm secureboot: enable (csb) Ap swrev: s1 t1 a1 p1 Secure download: enable Udc start. — Ashley
Solution: Hi Ashley. If your phone won’t restart normally, the only available option is to try to boot to other modes so you can do follow up troubleshooting. Here’s how:
Boot in Recovery mode:
- Charge the phone for at least 30 minutes.
- Press and then hold the Home and Volume UP keys, then press and hold the Power key.
- When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
- When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
- Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
- You can either wipe the cache partition or do a factory reset when in this mode.
Boot in Download Mode:
- Charge the phone for at least 30 minutes.
- Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
- When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
- Wait until the Download screen appears.
- If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
- Use Google to look for a guide on how to do it.
Boot in safe mode:
- Charge the phone for at least 30 minutes.
- Press and hold the Power button.
- Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
- Continue holding the button until the phone finishes rebooting.
- Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
- The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.
If your phone remains unresponsive or stuck in the same page or screen, there may be a hardware issue causing it. Have the phone repaired or replaced.
Hi. I bought my Samsung Galaxy s5 direct from Hong Kong. I live in Australia. When I try a software upgrade on it, it comes up with “The operating system on your device has been modified in an unauthorised way. Try downloading software updates using Samsung Kies on your PC or visit a customer service centre.” I tried a factory reset, but got the same message. The customer service centre just said it can’t be updated because it is an “international phone.” There must be a way. I haven’t been able to find it on the internet after hours of searching. Would you please help? — Kenf490713
Solution: Hi Kenf490713. The error message suggests that the phone’s firmware or operating system is not the official one. If you want to restore it to stock Samsung firmware, you must do so with the help of Samsung Smart Switch app, or by manually flashing an official firmware to it.
We don’t provide a guide on how to flash a phone in our blog so you have to use Google to look for it. Flashing is a risky procedure and may lead to more problems so make sure you do some research and using a good guide on how to do it. You also want to make sure that you use the correct firmware for your phone model. A good place to get such firmware is Sammobile.
Hi. Saw a web page Where you all are trying to fix lags. Well mine needs medication I think.
I tried following your instructions but I got nowhere. I’m having trouble even trying to figure out what kind of phone it is.
Okay starting off it gets hot at some point. it’s so hot I can’t put it against my face. now it’s to the point where it just says whatever is not responding then closes but it’s like almost on everything. it opens some and pages that I hadn’t even typed and some more like from months ago it just opens randomly. And it changes ringtones and notifications.
Then people can’t hear me talking on the phone but I did what you had on your site and it is a little better. So I hope you can help because I’m about to throw the phone and I love Samsung phones love them but this one is possessed. — Cathy
Solution: Hi Cathy. Taken altogether, all the symptoms you mention here may be signs of an on-going hardware malfunction. We say you try to master reset your phone and observe how it works afterwards. Master reset or factory reset will return all software settings back to their defaults. If the symptoms you mention remain after a factory reset, that’s proof that there’s a hardware issue. That means that you need to send the phone in so it can be physically checked and examined. Only then can you know if a repair will help fix it, or if you need to have it replaced.
For reference, below are the steps on how to factory reset your phone:
- Turn off your Samsung Galaxy S5.
- Press and hold the Volume Up, Home and Power keys together.
- When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
- Wait until the Android Recovery Screen appears after about 30 seconds.
- Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
- Press the Volume Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
- After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.
When I got home I plugged it into the factory wall charger that came with it and it showed the charging symbol with 0% and proceeded to get VERY HOT! after about 2 minutes, I swapped out the battery from the other S5 (exactly the same model) knowing that the new battery was at 26%. When I installed it into my S5 it showed the same symptoms… 0% and hot after 2 min. My battery worked just fine and took a charge in the 2nd S5 so I don’t suspect the battery to be faulty. So.. what could be wrong with my phone?? It has been mostly reliable for 2.5 years and now this. The hot spots seem to be just below the camera lens near the SD and SIM ports. I have also tried all of the restart/reboot/card removal/battery removal methods and always the same thing. Please help. Thank you. — Derek
Solution: Hi Derek. Overheating in combination with any other symptoms is usually not a good sign. In many cases, it’s an indication of a hardware problem. If you dropped your phone or got it wet in water before, stop doing all software troubleshooting and just send the phone in. doing software troubleshooting for hardware issue is pointless.
If you never dropped your phone or got it wet, consider doing a factory reset like what we suggest Cathy above. If that won’t fix the issue you’re experiencing right now, you can assume that the hardware is bad. What that bad hardware is is for the attending technician to know. If possible, send the phone to a Samsung service center so a trained technician can examine the phone.
I have a desktop and a Samsung S5. I get identical emails to both. Last night when I was at a friend’s house, my phone would not automatically find the wifi. I dismissed it. When I got home my phone would not update my emails. I went to bed. This morning I thought someone hacked my email and changed the password. So I went on my desktop and could not log into my email. I went thru the steps to change the password. I did the same on my phone. I can now access my email only on my desktop. I am not sure if the wifi thing last night and the email issue are related. I still can’t get into my email on my phone. Please advise. Thank you. — Jessie
Solution: Hi Jessie. Telling us that you can’t log in to your email is not very helpful in identifying the cause of the problem. We need more information than that.
Since there’s very little information that we know about the history of the device, and the error message you’re getting, what we can suggest is very limited.
For starters, you want to make sure that your phone is connected to the internet either via wifi or mobile data.
Secondly, you want to ensure that there’s no problem with the email app itself. You can do that by wiping the email app’s cache and data. Here’s how:
- Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
- Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
- Once in there, click on an application.
- You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
- You should now clearly see the Clear Data and Clear Cache buttons for the application.
Thirdly, make sure that you reconfigure your account in the email app. Tapping on the Clear Data button will remove your account from the email app so you need to add your email account again. Make sure that you enter the correct username and password.
If, after setting up your account, the problem remains, contact your email provider for direct assistance. Make sure that you provide as much information about the problem to them as possible so they can diagnose the issue easily.
