So I have got this Samsung Galaxy Tab 2 3G 10.1" that has been lying in a cupboard for a around a year, mainly because I've been busy Now there's a family member of mine who would really need a tablet so I thought this one would be perfect for her!
From thinking I went on to doing and started with getting rid of the stock software and installing some nice custom ROM.
As I found out i couldn't use USB (probably busted data-cable), I rooted the tab using KingRoot and went on installing CWM recovery. Afterwards long story short: I've tried both CWM and TWRP, different ROM and android versions (Lineage, CM, Slim etc.) and different GApps packages from different developers but the problem still seems to come up :crying:
The problem itself is that when I've installed any of the above mentioned ROMs, all the GApps seem to not have been installed correctly (even though the installation process in recovery went smoothly) and basically none of them works (notifications saying that any GApp has stopped keep on coming up and I can't find any Google app in the menu except something things like "com.google.android..." or "com.android.vending...") otherwise everything seems perfectly fine.
Maybe there are others here experiencing the same issue or there's someone who knows how to fix this here, any help will be very appreciated :good:
Hello,
First, have you checked that the ROM you flashed was fully compatible with your device? Yes, this is obvious, but I have to ask.
Second, I'm not a ROM flashing via custom recovery fan... The best way to efficiently flash a ROM in my opinion is Odin-Download mode but whatever (your USB port is screwed, so pfu.)
Redownloading apps doesn't work for you? (updating the apk may fix that!)

Thanks for your reply!
Yes, I do have used ROMs compatible with my device as they've all are made for espresso3g (which is my device).
I know it's not really the best way but I'll keep on trying with custom recovery for some more time and then perhaps try buying a new cable, and see if that works.
Tried installing Google Play Store from APK both on a clean ROM without GApps and with, but it still doesn't run and keeps on saying that either Google Play Store or "com.google.process.gapps" has stopped.
Alright...
I'm out of idea x/

Hello...!
You could try the following....
1. make absolutely sure you are using the correct version of gapps for the custom rom you are currently using. If your custom rom is on android 6, you need gapps for android 6 for example.
2. after flashing gapps wipe cache/dalvik and make a factory reset BEFORE exiting twrp. You will lose personal data but since you are preparing to give the device to somebody else that should not be much of a concern.
Let me know if it helps, if it does not, I might be able to try and provide additional suggestions.
Good luck!

Hi and thanks for your reply!
1. The ROMs I've been trying to install are all android 6.0.1 and I've been trying with different OpenGApps packages for the 6.0 version which should work (except CM 12 which is android 5.1 with which I've tried OpenGApps and A-Gapps for Android 5.1).
2. Tried that with 3 different ROMs today and the results are following: Slimrom gets stuck in setupwizard which doesn't start, CM 12 starts but the same error as first seems to appear (I get notifications about GApps which stop working) and Lineage bootloops the lineage start screen.

Ok...
This is what I would do if it was my device and I was facing what you are describing. It might take some time and a little patience to do everything described here, but it might also work.
1. Usin Odin, flash latest available official rom for the device. Let it boot and complete setup.
2. Use odin and use CF autoroot to root. Again boot and complete setup.
3. Flash Twrp. Enter Twrp and flash latest flashable supersu.zip. At this time I believe is version 2.82. Again boot and let it reach your welcome screen.
4. Enter Twrp. Enter advanced wipe. Wipe everything except external SD and usb at least 3 times. Do not exit twrp.
5. Install you rom. Do not exit Twrp.
6. After installing your rom, Twrp will ask you if you want to wipe cache/dalvik. "Yes" but DO NOT reboot.
7. Install correct version of gapps for your custom rom (correct both android version and architecture version). Again twrp will ask you to wipe cache/dalvik. "Yes" and this time reboot.
See what happens. If it gets stuck, try entering twrp again and do a factory reset only, only once and reboot again.
If that fails again... I will at a loss here myself too...
I did a quick search here on xda on P5100, I am providing some links that you can take a look at. You probably already searched yourself but you never know...

If nothing else helps, perhaps the best way to go around this would be to find a custom rom with at least some google apps pre-installed, in order to save you the trouble you are currently facing.

Hey, just try uninstalling Google play services and install them again. I faced the same issue and now it's all working on my Samsung Galaxy Core 2
Hi everyone,
My phone has this restarting loop issue after flashing either Candy7 or CM13 ROM. Not sure if this is bootloop error because It got pass the Huawei booting logo, but as soon as it finish loading the Google App and go to the OS home screen it restart again and again. Worth noting that the phone restart from ROM loading logo (the blue face for CM13 or the Google Dot for Candy7), not all the way back from Huawei booting logo.
First I use TWRP to factory reset wipe, then advance wipe /system, /data, /cache / Dalvik, then install new ROM + Gapp, and got the sucess message, then reboot to system.
I also tried with out Gapp to save loading time, and it restart again when get to OS home screen.
Please advise what may cause this.
No issue when i restore back to B322 EMUI 3.1
I have US version unlocked MT2-L03, B322 version, unlocked bootloader, rooted, TWRP 3.1.1.0 installed.
I made a video clip of the looping: https://www.youtube.com/watch?v=Y7kRpdGN2qA
I'm going through the EXACT same thing. I tried CM13, CM14 and even CandyRom, and the same thing happened more or less. Even if I got the ROMs running for a while, eventually that LOD (Loop of Death) would hit and I'd have to again reflash. I'm now back to B322 (Lollipop) for stability.
Given that the SAME thing is happening on all those ROMs, it's leading me to think that perhaps there is a software issue with my phone. Not sure if this helps, but I do think it could be the way I updated to Lollipop (B322) from the original Jelly Bean (B148). I've done a LOT of digging, and it looks like the way I did it was not quite right, even though my phone has worked fine all this time.
Here is the XDA post that seems to detail the correct upgrade path to B322:
https://forum.xda-developers.com/ascend-mate2/help/how-to-update-unlocked-mt2-l03-to-t3422775
Basically, it looks like the correct path should be B148 (Jelly Bean) --> B309 (Lollipop) --> B322 (Lollipop)
Being rather new, I just flashed to B322 right off of B148. I am now wondering if this could be the source of my problems. Especially since I keep getting the "Error 7" for "unknown bootloader" whenever I use TWRP 3.1.1 to flash LineageOS or CandyRom.
But, if you successfully used TWRP 3.1.1 to flash, that means your bootloader was recognized (I got the Error 7). If that's the case, then we're both having the same issue and something else is indeed the culprit.
I strongly suspect that "something else" could be GAPPS. I've experimented with several GAPPS packages, and noticed that right before crashing and the dreaded infinite loop, something glitched involving Google apps.
Desperately want to leave Lollipop since Oreo is about to drop meaning we Android L users are in for a world of hurt if we can't migrate soon. :-\
I upgrade my phone B148-B309-B322. I also get error 7 whenever I flashed the ROM, so I have to manually delete '"assert" command line from ROM script to flash successfully.

My phone has been rooted for over a year now, I've had many roms on it doing that time. This loop started with a app I updated from the play store. Not sure it may be substratum will look into it when I have more time..
These problems is because of the room. Try to install lineageOs.
Thanks Kevinoriej,
Same looping issue on LineageOS, after loading to OS homescreen , phone restart.
Also get error 7, and manually remove "assert" lines in the ROM script in order to flash.

I believe the Error 7 message is because your bootloader is showing as "unknown". I downloaded an app from the Playstore that gave me my device's technical info, and sure enough, my bootloader is listed as "unknown". I forwarded a question to Huawei's EMUI team asking them if that happened due to unlocking it (using Huawei's official unlocking request). Still waiting for a replay. In order to get any of the ROMs to install, I had to downgrade TWRP to 2.8.7.0. Any version above that would trigger Error 7.
Out of curiosity, I then downgraded and flashed CandySix (with a corresponding GAPPS package) - and sure enough, the same looping happened. And again when I flashed CM13 AND LineageOS. The phone would successfully boot, get to the actual Start screen, and then boot again. I could NEVER predict exactly what triggered this. Also, I tried installing ROMs without GAPPS, and that didn't go well for me (couldn't get any of them to load properly without flashing a GAPPS package for some reason).
Something goofy seems to be happening between Google services and the custom ROMs on this phone. I'm not sure what's triggering it, but given the sheer number of different ROMs I've tried - ALL of which have the EXACT SAME ISSUE - I strongly suspect there is indeed a GAPPS problem lurking somewhere.
As a side note - I reflahsed B322 (restoring from backup) and the phone is again as stable as it has always been.
Is there an EMUI GAPPS package for Marshmallow and/or Nougat (i.e., pulled from Mate 7, 8 or 9) available for download? I'm game for testing.
RE: MT2 boot loop
(*** SEE POST #25 FOR UPDATED FIX!***)
I just noticed this thread, wish I found it earlier. I recently posted my discussion of the boot loop (and fix) here:
https://forum.xda-developers.com/ascend-mate2/orig-development/cm-nougat-mt2-t3478345/page14
Bratzilla was right when he said in his post, "I strongly suspect there is indeed a GAPPS problem lurking somewhere".
Thanks EndlessFall,
please help to check this link: github(dot)com/opengapps/arm/releases/download/20170811/open_gapps-arm-7.1-pico-20170811.zip

RE: dead link for Open GApps previous versions & boot loop fix
Strange, it seems that in the past day Open GApps has purged their GitHub archive. The "Older Releases" button at their website still redirects to the GitHub repo, but it no longer displays any version other than the current one.
As long as it does not violate any policy, I can always post a copy of the Open GApps 08/11/17 ARM 7.1 Pico package.
Although I have not tried other GApps distributions (Delta, Beans, etc), in theory there is no reason why they shouldn't work, as long as Google Play Services is not newer than v11.3.02. I recommend the minimal GApps available. Installing "pico" was an important part of isolating, and simplifying the search for, the culprit.
As I mentioned in my original post, I tested all versions of Google Play Services on apkmirror newer than v11.3.02 (build format 436 for MT2L03), up until 08/26. All newer builds induced an immediate boot loop. A future version may resolve the boot loop issue and work fine on the MT2L03, but it does not seem to be available as of today.
Have been running custom ROMs on my MT2L03 for years. Boot looping problem began for me two weeks ago when I completely wiped/formatted my CandyROMs v7.1.2 06/15 install and flashed MDMower's 08/19 LineageOS. Began digging deep into the cause (knowing MDMower would not release garbage) and discovered the connection to Play Services. Have been running MDMower's LineageOS & CandyROMs v7.1.2 ever since without any issues.
Remember to use MDMower's TWRP v3.1N0-0, it is much more stable on the MT2L03.
Thanks again Endless,
I follow your instruction to flash Candie ROM and the matching GAPP from 6/15, all went well, no more bootloop. I will check the phone from time to time to see if the Loop of death come back, maybe once GAPP get updated it may come back. LOL... hopefully not though.
RE: MT2 boot loop fix (workaround)
Great, hondaman82 - so glad it worked for you. Funny, the exact same environment that you are using (06/15 CandyROMs with the matching 06/15 Open GApps) is what served as my "proof of concept" that current Open GApps with updated Play Services was likely the problem.
Although the proper GApps package resolves the boot loop issue, it is important to point out that it's more of a workaround than a fix. The root cause might be a bug in the AOSP/LineageOS source code itself, preventing MT2L03 compatibility with the latest versions of Play Services.
MDMower has just released a new build of LineageOS dated 08/29/17. I'll continue to test the latest ROMs with the latest GApps & Play Services to see if new commits/updates fix the problem...

Oh nooo.. the LOD (loop of death) come back, after 3 days of working OK... sigh.... back to EMUI stock
RE: new ROM builds, GApps, & boot loop issue
Yes, I tested MDMower's LineageOS 08/29 last night using the 08/29 Open GApps package. Unfortunately, the boot loop bug persists. However, the 08/29 LineageOS runs great with Open GApps 08/11 and is worth installing (at least for me). Hopefully MDMower will keep up the good work and release a build in the next week or two with the Sept security patch.
I'll continue to test and report back if there is any progress...

RE: return of boot loop
Sorry to hear that Hondaman82.
I can only speak from my own experience, which is that my MT2L03 has been stable for the past 2 weeks using Open GApps pico dated no later than 08/11. It is possible that your Google Play Services was auto-updated to a version newer than v11.3.02 (inducing the loop), but you won't be able to tell because you can't boot the corrupted OS to read the version number in app settings. If my boot loop returns, I'll do an ADB pull from TWRP to examine the Play Services package version (curious to see if there is an update correlation).
Goes to show what I mentioned yesterday, which is that the root cause is likely some incompatibility between the ROMs customized for MT2L03 and Play Services that can only be fixed by a commit to the ROM source code, a script, patch, or change to Play Services.
Let's see what happens, perhaps MDMower would be willing to offer his expertise? I visited Matt's website, GitHub and XDA profile, but it seems difficult to contact him directly....

RE: preventing Google Play Services auto-update
(***SEE UPDATED FIX IN POST #25!***)
For those of you willing to experiment further, there is a method that supposedly disables Google Play Services from updating. This might allow you to "lock in" v11.3.02 until there is a proper fix for the boot loop:
https://forum.xda-developers.com/android/help/delete-disable-downgrade-prevent-update-t3091832
Basically, this involves using a root file manager to create two empty folders entitled "com.google.android.gms-1.apk" and "com.google.android.gms-2.apk" in the "\data\app" directory, causing auto-update to fail.
I haven't used this hack, try at your own risk!
Of course, this works off of the assumption that updating Google Play Services beyond v11.3.02 is the only factor involved in the boot loop. I just haven't dug deep enough...
Mine (Candy 0725 build) went into LOD by itself a moment ago
Does anyone have a B322 TWRP backup ZIP? I as of this morning have 2 MT2 phones dead. One went into LOD about 3am and the other about 4am.
Hi all
I am trying to upgrade a Lenovo Tab 3 (TB3-710F) 7" tablet because Android 5 is the latest official version. Ideally, 7 is better, but I will be happy with 6. I have downloaded SP Flash Tool and TWRP 3.0.2, and that is installed correctly and all working. Now the actual ROM is the problem. I have downloaded Resurrection Remix, LineageOS 13, Viper and Dot, and it would appear most of them have the same problem. When I try to install the zip file, I get told that it's unable to unmount or mount /system and it crashes out with signal 11. I have tried to wipe and reformat the system folder, again being told it's unable to unmount /system, and have changed the file system from NTFS or exFAT and back to Ext4, but to no avail. I suspect until I can format the system folder correctly, it won't install, but for the sake of me, I can't. Has anyone got any advice?
bump
A custom rom would be great for the tb3-710f.
I have just done a factory reset and most Google apps won't run because play services can't update.
bump
I've just upgraded to 5.1.1 on a TB3-710F using an old CyanogenMod cm-12 custom rom so that I can use Google's FamilyLink, works well.
Do you have a link to the LineageOS 13 rom?
I also had a similar error installing the cm-12 rom but that was because I'd missed wiping /data in TWRP first before attempting to install the rom.
YESS>>> We need lineage os for TB 3-710f.. I too use cm12
SOOOO.... Anyone??
I too have CM-12 on my Lenovo. so anywhere have a link to download any custom ROM but not CM-12.
let me explain, firstly

because all of those ROMs are not compatible with your device. that is why it won't flash. If you force it to install that specific ROM, it might end up in a boot loop. You must have not deleted all your files. :c

You did not upgrade though. The tablet is literally on 5.1.1 so maybe you did this because you hate the lag of its own UI provided by Lenovo. Well that is a good choice. Although, it does not make any difference between the apps that you can run and can't run because it is still in the same version (Android 5.1.1).
To be honest, even if you try to find a Lineage OS ROM, it is useless because it is not on the list of supported devices. Almost all custom ROMs do not have this tablet on their list (I hope they added and modify some **** because we really need it :c). For now, the only custom ROM that I know this tablet can have is Cyanogenmod 12. It is your own choice if you want to install the buggy ones. The buggy ones are, Lineage OS and Flyme OS.

Lineage and Flyme doesn't install for me.
Did a clean install with the stock TB3-710F_S000028_170316_ROW. Then format. Then tried to install the two ROM's.
I noticed the install log shows the variant 710X. My tablet is a 710F
What am I doing wrong?

nvm. Do not risk it. I installed CyanogenMod not those two. Sorry for misinformation.

No problem.
I'm struggling with CyanogenMod running super slow and freezing regularly. I have found two links. Using SP Flash Tool, I first flash stock TB3-710F_S000028_170316_ROW and then recovery_twrp302_Lenovo_TB3-710F
Then I flash these ROM's. One that a time

Hello, was the last stock rom very slow too? Might be Google services that make the device lag

No, stock is ok.
So, I install lineage os every one's and a while to test it and see if it is ok for me, I always revert to stock but that's not the point, one problem that I have is that the phone gets VERY HOT. One day I installed lineage and when I finished the setup process, the phone was so hot I couldn't hold it comfortably, while when I finish the setup on the stock rom the phone is just warm. Is there any way to make the phone run cooler? Is the phone getting hot because the software is too much for the processor? . I haven't installed lineage os for about two months now so I may try it again at some point. Is anyone else having the same problem?
No that's not normal, it's not supposed to heat up much.
Maybe you you didnt flash it properly, it's recommended to install it like this.

Also check before flashing if your camera works on the stock lg rom,
If it doesnt you have to downgrade to stock marshmellow, and then upgrade back to oreo to fix it.

Thanks for answering,
This is how I install it. The camera on stock oreo is working normally so I don't need to install stock Marshmallow. So, I firstly unlock the bootloader and then install lineage os 15.1 with no gapps. After that I upgrade to lineage os 16.1 again with no gapps. Now I uninstall lineage 16.1 and I am doing a clean install of official lineage os 17.1 WITH gapps. The reason I do this is because if I install lineage 17.1 instantly the cameras and sensors don't work. Unfortunately I don't remember the temperatures that I got but I remember that one day I woke up with 20 C and after 15 minutes of some web browsing and social media it went up to 40 C (there's a slight chance that I'm wrong since I don't remember the exact temperatures as I said)
Strange i didn't have those problems when flashing properly,
Do you also use nano/pico opengapps?
You could also give crDroid Android 5.12, a try maybe that will work well, but it's android 9 instead of 10.
I think you need to flash it in the same way as lineage.

I originally used nano opengapps but I started using stock because I use most of the gapps anyway but I will try crdroid 5.12 at some point to see what happens.
Build in the works. Going to release the BETA as soon as I can do testing on my own device before release.
IMO this is a necessity as there are literally no good roms for this right now. I tried the port of the Nexus stock CR rom and it was not great. Playstore was unusable due to an issue were the app thinks the system is out of storage space, even though it is almost empty. Chrome crashes instantly, the search on the page home screen flickers up/down without control.
I am a far bigger fan of LineageOS thus why I am working on this build.
More to come.

As a follow up to my original post I wanted to mention that for anyone who wants a new ROM on their SM-T290 until this is finished development, use the Nexus Rom by Magendanz. I was able to do a fresh stock firmware install and retry the rom and my opinion has changed. I have noticed that these Tab A 8.0 tablets have been used a lot for like Uber/Door Dash and other POS terminals. I am pretty sure a lot of them have modified or customized firmware for these reasons and when I mine second hand it was from a pizza store. I think that messed up the upgrade.
Overall Magendanz did a great job, when you install it properly. I have zero issues with functionality now, TWRP recovery set up, as well as Magisk installed and everything is running extremely well.
As far as instruction on how to install. Take a look at some of the comments further down on the Nexus thread. That is what I did this time around and it worked perfectly. Last thing I did was copy Magisk.Apk to my SD, change extension from .APK to .ZIP, then boot into TWRP and install that ZIP.
Going to update progression on a monthly basis as far as the LineageOS 18.0 build

Do you have a github with your source code and manifest? I just got this tablet (used) yesterday and I would like to see if I can help. I have built LineageOS roms for a number of older Samsung Tab A devices, but will have to do some research on the "new to me" T290. Thanks.
Just got this tablet, how's the beta coming along? And what can I do to help?
Thank you my guy I had lost all hope for custom roms on this tablet. It's quite relieving to know that I'm not alone.
Also, has anyone experienced severe lag on one ui 3 while doing basic tasks? The thing literally gets 5 fps while watching youtube and surfing the web but it plays 3d games at 20 fps on low settings. wtf

Hey Guys,
I didnt end up building a custom rom, because I was able to get the GSI version of Lineage 19 working fairly easily. Just use the correct image and flash the same as the Nexus post. Android 12 with Lineage 19 so i felt it wasnt worth it as everything works. I had trouble at first with a boot loop but that was because I had installed Magisk BEFORE the GSI rom and not AFTER. So dont make my mistake.
As per the Nexus Post;
Unlock Bootloader
flash TWRP
Wipe data
Install Andy Yan's Lineage OS 19 GSI
Andy Yan's personal builds // GSI - Browse /lineage-19.x at SourceForge.net
sourceforge.net
Install Magisk
Reboot
Cheers!

Good advice But which of Andy's GSIs did you use exactly ?
Thanks so much dude
The GSI is a .img.xz will it work or does it need to be .gsi

You download the .img.xz file and unzip it.
Inside this will be the .img file
This is what you need to flash (.img)

Sorry
Use this one
lineage-19.0-20220211-UNOFFICIAL-treble_arm64_bgS.img.xz
It has Gapps built in as well as super user through SSH, dont install Magisk as it will error that there is already SU tool installed.
@SniperFox22 , did you make a github for the code or didn't even start since you are happy with GSI?

My OS didn't have an option to unzip it at first glance. I haven't been able to install gapps so I'm gonna try that gsi. Also, am I supposed to wipe internal storage before flashing or not?
I got it working but games just crash which is worse than before
Came across this while trying to root my sm-t290. Just want to add that Andy Yan has upgraded to a 19.1 version that appears to work just fine. Flashed to system partition using twrp after I had flashed the Nexus rom. Wifi works, sound works, sd card, bluetooth keyboard works just fine.

Link to it???
I like the link above because it has all the versions but lineage-19.1-20220320-UNOFFICIAL-arm64_bgS.img.xz is the one that I used. The page has the naming convention. Ill mention that even though it says that it's supposed to be rooted, I couldn't get it to work right. The nexus rom had an option in the 'phh treble' menu to activate root and this lineage image should also but the option wasn't there. It kept saying the supersu binary was busy but that was after I flashed a supersu.zip(it may have worked before then i don't know). I played with it a little bit but ended up just flashing back to the Nexus rom.
Hey guys!
Installed "lineage-19.1-20220320-UNOFFICIAL-arm64_bgS.img"
Everything starts up, but something is weird with my installation and my storage, it freezes when i go into storage and i cant download anything without apps start to crash.
Im not sure if i flashed it correctly, i did a wipe in TWRP before installation.
Really hope i can get this to work since it waaaaay faster then the bloat samsung ships
Edit:
Tried flashing another rom (nexus) and had the same issue!
trying to reflash and wipe everything except internal storage.
Where should i flash image? i get: "select partition to flash image", never seen that before (might be because you flash img and not zip)
