Custom Recovery not working

Hi everyone,

I'm new here and to doing anything with android at all. I've been doing a lot of reading today and I thought I was good to go with trying to change the version of Android OS on my tab 2 10.1 ( model number SAMSUNG-SGH-I497) I mainly want to do this because as it is with android 4.0.4, it can't download the apps I want, so if there is a work around for that then that's all I need.

Okay so my plan was: root the device, download the custom recovery, then try and find a custom ROM and then... I think from there I can change the OS? I was able to find a root through chainfire and I believe that the device is now rooted ( when I open apps like TWRM manager it says they have been granted superuser access). However, I couldn't find any recoveries that were specifically for model SGH-I497, and since the ones I did find said they were for all types of galaxy tab 2, I figured I would try it. So, I have tried flashing a couple different files and then booting in recovery to set it as the default recovery, and the first time it got me stuck in a loop where it would show the samsung and say "booting recovery" at the top, and then after half a second shut off again. I was sure I bricked it, but after a lot of fiddling was able to get it into download mode and I flashed the same .tar I had used and it let me use the tablet again. That first time was with the newest espresso3g.img TWRM done through the app. Then I tried again with the espresso3g.img.tar ( I don't really know the difference) and flashed it straight through odin. This still wouldnt boot in recovery but I could get to download mode with the volume button this time so I flashed again to fix it. I tried one last time with an older espresso-common file again through odin, and it didn't work either. I am worried that I might do something irreversible at this point, so I figured I would ask for help here. Am I using a file that doesn't work, or am I doing something wrong? any help would be appreciated, thanks!
[Galaxy Tab 2 Q&A, Help & Troubleshooting] Android-Andi:
P31xx and p51xx files are not compatible with SGH-I497, flashing those files could brick your device.

For your variant there has never been really active development, not sure if any.
[Galaxy Tab 2 Q&A, Help & Troubleshooting] Matt117:
So basically, I'm SOL with being able to download newer apps on this tablet unless I can find a specific recovery and rom developed for this tablet? That makes sense, thanks for the help.
[Galaxy Tab 2 Q&A, Help & Troubleshooting] ze7zez:
.

I think there's a chance for you.

.

After doing root on the sgh-i497 and getting recovery.img from the appropriate partition you can try the method described in [GUIDE]Porting TWRP without source.

.

I can't tell you anything else because I haven't tried this method yet.

[Galaxy Tab 2 Q&A, Help & Troubleshooting] EEngineer:
Make sure you are using a high capacity wall charger like a 1.8A wall charger because a low capacity charger will give you that red X on the battery icon. Don't bother charging from a computer's USB port as it won't source enough current.

Also make sure you have a good cable, as some of the aftermarket cables are okay for data transfers but lousy for charging. Keep the screen off while charging, as on this tablet screen-on charging can take a very long time, or even not charge at all.

There is an app called Ampere that shows you the charging current, I suggest you sideload that and make sure your charging current is above 800mA.

As a last resort, charge overnight with the tablet off to minimize power loss during charging.
[Galaxy Tab 2 Q&A, Help & Troubleshooting] BrainSoldSeparately:
Thanks for the tips about charging, however my main issue is the fact that I can't flash anything onto the device since it wont show up in the system (linux and windows with drivers), do you know what might be causing the behaviour I described in my previous post?
[Galaxy Tab 2 Q&A, Help & Troubleshooting] EEngineer:
Well, I can't directly help you but this tablet suffers from low power issues. On this tablet battery problems are often a symptom or cause of a seemingly unrelated problem.. So like car OBD codes sometimes fixing one Android problem fixes another seemingly unrelated problem. So I suggest you find a way to charge your battery to 100% without the red X and see if that fixes the issue.

For example it's possible that you have a bad cable, which would explain both the charging and the ADB problems. So fix what you can fix first, and then see what problems are left.
[Galaxy Tab 2 Q&A, Help & Troubleshooting] BrainSoldSeparately:
So, I charged it to 100% when it was off on powerbank and when i turned it on and plugged in to the laptop it still didnt respond to setup address (the same errors in dmesg as previously posted).

I ordered a new cable in case the data lanes on the one I'm using were broken or something, however it won't be here till Wednesday, is there anything else I could try in the mean time?
[Galaxy Tab 2 Q&A, Help & Troubleshooting] EEngineer:
I'm not familiar with Archlinux so I'd suggest trying to connect with ADB using a different computer.

[Galaxy Tab 2 Q&A, Help & Troubleshooting] BrainSoldSeparately:
Ok, so the new cable arrived today and I installed windows 10 pro 64bit on my second laptop (I was previously testing on windows server 2019), however with the new cable the behaviour is exactly the same on linux and on the mentioned laptop as before.

Here is the tutorial I'm using btw: https://wiki.lineageos.org/devices/espresso3g/install

any thoughts?
[Galaxy Tab 2 Q&A, Help & Troubleshooting] EEngineer:
I recall having a similar problem a while ago, I dimly remember that it was my firewall or antivirus that was blocking it. But you have the same issue on both Linux & Windows which points to a tablet configuration issue.

Double-check on your tablet that you have debugging and ADB enabled in Developer Options. If it's not enabled, enable them. If they are enabled, cycle the setting (disable it, wait 5 seconds, then re-enable).

Also try booting the tablet into Safe Mode and see if you can connect via ADB there.

Hello I am from INDIA, I tried to repair my Samsung Galaxy TAB 2 it was stuck on samsung logo. So I tried to install stock ROM with odin and I was able to go into download mode. but I guess I was tried to install wrong firmware. now the screen on display "Firmware upgrade encountered an issue. Please select recovery mode in Kies and try again" . I tried to run emergency recovery mode in Kies, but there was no recovery device list. So I tried to install twrp file from odin, but it showing fail status. So in short current condition is TA is SHOWing "Firmware upgrade encountered an issue. Please select recovery mode in Kies and try again" this massage I CANt go in revovery or download mode, but device is only showing in odin. can someone please help me to resolve this issue . I want to use this tab. Thanks in advance.
[Galaxy Tab 2 Q&A, Help & Troubleshooting] drnightshadow:
Maybe your tab has emmc issue... in short your tab died... many tab2 has/had issues.... you can google it about that.

Another idea... do you use win10? If you do than try using usb2.0 hub or search for reg fix on xda forum. Or if you can use win7.

Hope you'll fix the tab.

Good luck!

P.s.: another idea... try using pit file for tab2 in odin to flash firmware. Maybe just partitions are messed up. Be careful that pit is for your tab2 model like p5100 or p3100. If you put the wrong you'll bricked your device.

Hi! I'm having a few issues with my tab 2 10.1 p5113.

They might be vary basic but I would hope you can help me sort them out.

I'll start by saying that I'm not really a tech person. This is my first custom android install and I'm greatfull for people on this community. Sorry in advance because English is not my first language.

I installed lineage OS 13 or 14? The android 7 one and it was REALLY slow and unresponsive.

The official ROM was really slow, even more unresponsive that lineage was. It had android 4.1.2. Or 4.1.1.

I'm now on omnirom with android 6 and gapps. But I'm not having the best performance.

Its useable more than ever but it gets really slow at times and for some reason the battery started to die in standby randomly. When going to sleep with 100% I wake up with 0%

I only plan to use it for very basic tasks

PDF readin (xodo) {main purpose}

Docs

Music (from YouTube music)

Video streaming (YouTube, amazon [Netflix can't log in] and stremio)

I can do this things but its not really fast and even reading PDFs lag a bit when scrolling. Also when I try to play video from the web or play something GPU intensive I get graphical issues. Videos online get a flashing pink borders and games show like a lot of squares of differents colors and crashes to desktop.

One last issue that I seem to have is that I have less space than I used to. Its a 16 gigs tablet and I only have 6 free even tho I did a clean install. Maybe I didn't erased the old android right? cause I don't know how to. Could this affect performance ?

Here are my questions:

Should I try another ROM and if so, which one do u recommend ? Or let be as is.

How many times can I install ROMs before the "red triangle" appears? I have 2 custom ROMs so far

Is gapps really necessary / does it have a high impact on performance?

I'm open to try any suggestion. I can sacrifice everything on the list of usage except PDF reading. If I could turn this into a kindle sort of its fine by me.
[Galaxy Tab 2 Q&A, Help & Troubleshooting] Mighty:
Yes, android 7 roms have had issues with being slow and laggy, its better to use marshmallow(6) as it gives better performance than 7.

Whats the "red triangle"?

Gapps is Google Apps, they arent necessary but without them you wont have Google stuff (like Play Store etc) but without them the performance and battery is usually better.

The doctor for your tab 2 is here (me) !!!!

I'll tell you a great trick to resurrect your tab 2.

Install this rom- https://xdaforums.com/t/rom-resurrectionremix-v5-7-4.3502188/

Gapps- http://xdaforums.com/android/software/app-minimal-gapps-gapps-lp-20150107-1-t2997368

Once you install rom and gapps and set up your device, reboot to recovery and install this kernel- https://xdaforums.com/t/kernel-6-noob-kernel-22-01-2019-updated-oc.3891205/

ENJOY YOUR TAB 2 !!!!

NON GAPPS METHOD:

For YouTube music and YouTube, gapps are necessary. However, there is a modded version of YouTube which doesn't need gapps called as YouTube vanced https://youtubevanced.com/

Steps:

1) Install the rom without gapps.

2) Install the kernel.

3) Install vanced manager app- https://youtubevanced.com/downloads/manager.apk

4) Launch the app, select no root and install microg (modded version of Google Play services).

5) Install YouTube music and vanced.

Done.

If you want an app store, use Aurora Store (Google Play Store client)

App store- https://www.google.com/url?sa=t&sou...FjAKegQICBAC&usg=AOvVaw3WiIjE2p3DPKNl-7FK5zEN

Some apps might not work because of no gapps but you only want to read PDFs and watch video and listen to songs. I'll suggest you to install Microsoft word as it works without gapps

ENJOY YOUR TAB 2

Hi

I can't really say what it is, but I have read somewhere on this site (can't find it right noe) that if u install too many times a new android version, a red triangle will appear on boot. I don't know if that means that it will brick itself or if its just like a warning.

I don't get a good battery life compared for what I have seen from reviews. Maybe 5-6 hrs max with WiFi off and reading a pdf with medium Brightness. But I can't really complain cause its a really old tablet from 2012 and its been use a lot trough the years. Also I got it for free so that's a bonus.

Hi and thanks for replying.

I Will defintly try this ROM since it looks really promising for the comments of the post.

As soon as I finish this semester I will do it since I have my books here and all my notes on them and I'm really close to finish.

Thank you very much!

Hello everyone,

been looking around here for a while but I'd say it is better if, before doing anything real silly, I ask to you, knowledgeable folks.

I have a Samsung GT-P6200 (7") fully functioning, still with decent battery and all but stuck, of course, with a very old and by now useless Android version (3.2 !!).

I'd really like not to throw this thing away and even if i was to gift it i'd rather have it in a modernized version, if possible.

Could you please point me in the direction of a comprehensive guide and a rom version that would fit on this thing (still a beauty after a lot of years).

Thank you very much! Any suggestion is very much welcome..even "use it as a fancy doorstopper" :D

cheers.

So I got pretty far with the TAB 2 5113 up until the loading a new rom thing.

Followed this guide

https://xdaforums.com/t/how-to-root...p5113-5100-5110-4-0-4-upgrade-or-oem.1657056/

Installed phil > rooted GREEN > It said Modified under settings > I put the lineage ZIP file on the root > reboot, then try to install and it fails with error 7 this device is expressont (expressonr?) and it will kick me back out.

Any ideas on why this is happening?

The one I'm using is;

espressowifi (P3110, P3113, P5110, P5113)

lineage-14.1_espressowifi-7.1.2-20200623-1924.zip

Should I try 3G instead of WIFI even though the model is not the same?:

espresso3g (P3100 & P5100)

EDIT...................................

I tried to install Orion OS!! instead

I chose Wipe the cache partition and then chose clean to install a new ROM, then loaded the ZIP

It's the closest I've gotten to installing a custom ROM

OrionOS system files verified

Flashing SuperSU

unmount of /system failed: no such volume

script succeded result was []

install from sd complete

press any key to continue

I then reboot and get taken back to phil, i reboot a second time and there was an orion logo, but it just stayed on a gif of planets after that

maybe i did something wrong along the way

or should i wait more than 10min? (orion page says it does it in 4)

Hi, I have a SGH-I497 very slow, that's why I rooted and deleted plenty of apps until it cannot run. I unrooted it with odin into 4.1.2 version but now there's a problem with Play store's no connection error. I can't run APKPure apps (parsing error) and even default browser doesn't run (network error). I try everything I found to solve it, cache, Google accounts, root again, but nothing can solve it. Help!
[Galaxy Tab 2 Q&A, Help & Troubleshooting] EEngineer:
You probably deleted one or more essential system apps such as Google Webview. In that case you'll have to do a factory reset to recover. Back up all your data & apps - Titanium Backup is great for that.

After the reset, DO NOT CONNECT TO WiFi. Sideload any apps you need. Root it again if needed. Once rooted, only delete non-essential apps. Do not delete any system apps, Google Play Store or Google Play Services, Maps, Webview, or Framework. Delete any AT&T branded apps (that will speed it up).

After that, install a firewall and block non-essential apps for a real performance boost. Only after installing the firewall and blocking apps will it be safe to connect to WiFi.

Afterwards, you can try deleting other apps but back them up first. If you delete an app & suddenly you get your original problem, you have found the app that caused your error and so restore that app from backup.

Alternately, instead of a factory reset try booting it in Safe Mode and see if you can anything to work (sorry I'm not familiar with safe mode). If it won't work in safe mode then a factory reset is needed.

I have Play Store and Framework on my Galaxy Tab, but I did not log into my Google account so Google can't really do anything rude to my tablet.
[Galaxy Tab 2 Q&A, Help & Troubleshooting] Prtndr:
Thanks for your response Eengineer. At this point I don't have any data, so I just did a factory reset (from settings/backup and reset). As you said, I didn't connect to wifi and just connected to my laptop and copy an APKPure.app.com (chrome browser) , but as I commented before when I try to run it, my tablet reports a parsing error, "There is a problem parsing the package". At this point I don't want to erase any app, just want to install a better browser (chrome or other) by the Playstore or APKPure. Appreciate if you can write a firewall that I can use but I don't see how I can install or run. Thanks in advance.
[Galaxy Tab 2 Q&A, Help & Troubleshooting] EEngineer:
"A problem parsing the package" probably means the APK is not compatible with your version of Android. Get a version of the app compatible with your version - are you running Android v4.1.2?

For firewalls, AFWall+ is a popular and powerful firewall that only runs on rooted devices. It has a lot of options and is compatible with a VPN.

NetGuard is also a popular firewall that runs on unrooted devices. It does this by creating a VPN that routes all traffic. It is not compatible with a VPN. It does have a cool feature, a LAN-only mode where the device can only access your WiFi LAN but not the internet.

Both firewalls have a bit of a learning curve & so you must spend time reading the documentation. Make sure you get an APK compatible with your version of Android.
[Galaxy Tab 2 Q&A, Help & Troubleshooting] Prtndr:
Very thankful for your responses. As you said, problem with parsing is because android version. I have a chrome app and a AFWall+ compatible with my 4.1.2android version. Thanks a lot. I still have the play store app error "no connection" that I think is also because compatible versions and because of that I cannot run YouTube app (needs play store services upload -by Play store 🙄-), but at least a runnable browser app. Now, deal with RAM memory a slowly operation...😅👍

Hello everyone!

Can anyone help me with my GT-P5100 pls.

Tried a successful factory reset on my tab but it did not automatically reboot anymore.

After pressing power button (without pressing any volume button) it automatically go to recovery mode.

Tried to flash stock ROM and custom ROM zip files using TWRP but after flashing, when I press the "reboot" it does not restart automatically. Then when I press the power button, it goes to TWRP again. Same problem goes after flashing MD5 files using the odin method.

I even tried the ff:

* disconnect/connect the battery

* disconnecting the power volume button flex cable after pressing power ON (thinking it may have a grounded volume buttons)

but still it won't boot up and I goes to TWRP again.

Is it something with the hardware? or maybe I messed up the system by flashing several firmware versions?

Can anyone help me how to restore it?

Thank you so much in advance.

Hi. I have a P5100 with a clean AOSP rom flashed. I've bought a used official keyboard dock for my tablet, but it won't fully work. Android detects when I connect/disconnect it judging from the system chimes, the passthrough charging works and that's it, keys and the built in passive jack aren't responding, although the latter seems to be powered when I connect the headphones.

So, before I flash the original android 4 firmware back and test the keyboard further, can anyone share their experience of using the official keyboard dock with an unofficial rom booted? Thanks.
