[Q] My CWM 3.x.x.x backup doesn't work : SGS2

Hi,
I checked through many threads to see if anyone had a similar problem but couldn't find anything unfortunately.
Background :
I was running a Lite'ning ROM on my Samsung Galaxy S2. You're probably familiar with this ROM, but for those who aren't it gets flashed with ODIN and comes rooted and pre-installed with CWM.
I forget which version of Lite'ning ROM it was, but I am fairly certain it was pre-1.5 as the bundled CWM was definitely version 3.x.x.x (later versions I found had 4.x.x.x and 5.x.x.x).
I wanted to try a version of GalnetMIUI for something a bit different and hadn't changed ROMs in quite some time, so I booted into CWM 3.x.x.x (maybe 3.0.0.2?) and did a backup to the internal SD. This came in at around 1.4 GB and comprised of 4 files :
cache.img
data.img
nandroid.md5
system.img
I copied these to my PC too, just in case they somehow got erased from my phone.
Once I'd done this, I then copied the new ROM .zip file (latest version of GalnetMIUI) to the root of the internal SD, booted the phone into CWM, wiped user data and Dalvik cache, then proceeded to install it.
The problem :
I can't get my apps or data back. I was under the false impression that my Google account was automatically backing this up for me, and would restore everything once logged in as it had in the past (factory resets etc.). So once this didn't happen, I tried using CWM to revert back to how things were before installing the new ROM but although the restore appears to work I end up with issues.
I've tried a number of different ROMs and they either get stuck in 'boot loops' or a black screen after running through the restore procedure. I've tried restoring just data via the 'Advanced' option but this doesn't help.
I was under the impression that I'd be able to fully restore the ROM backup if I needed to, and have the phone running exactly how it was prior to messing around. It would seem this is not the case.
In desperation I tried flashing every Lite'ning ROM from version 1.0 to 4.2, restoring my backup each time but as mentioned I always get boot issues.
Have I lost my data? I hope not, as I had 'To Do' lists and all sorts of things that would cause problems if they were not retrievable. I realise this is a lack of knowledge and foresight on my part. I'm thinking now that I should have run Titanium Backup prior to this, and not assumed that CWM was going to provide a complete solution.
Hope all this makes sense and if any of you have the time to read through and offer advice it would be greatly appreciated. I am currently running a very pretty and slick GalnetMIUI without any of my data!
Thanks in advance.

Thanks for that, I'll give it a go tonight after work. Am I right in thinking that if it doesn't work I can extract the individual files and insert them manually to get my app data back?

OK, so after hours of searching I'm still no wiser as to how to install CWM 2.5.1.2
I found a zip file that was apparently version 2.5.1.2 but when I tried to install it from inside CWM 5.0.2.6 (included with GalnetMIUI) it sometimes gives an error, sometimes it reboots CWM and sometimes it simply says it has successfully installed (it lies). No matter what it says or does, it doesn't seem to actually replace version 5.0.2.6 with the older one and every time I do the three-finger boot it loads up the latest version like nothing changed.
I'm just so lost. All I want to do is restore my old backup, get my data back and move on. Please someone help me before I go insane from all this research!
[EDIT] In case any more information is needed, my exact procedure for installing version 2.5.1.2 of CWM went like this :
Download 2.5.1.2 zip file
Copy zip file to root folder on internal SD
Boot into CWM 5.0.2.6
Select "install zip from sdcard"
Select "choose zip from sdcard"
Navigate to 2.5.1.2 zip file, select and confirm

Can anyone help me at all?
In particular I'd like to know how I can downgrade to CWM 2.5.1.2 or similar in order to give [email protected]'s suggestion a go.
Failing that, if anyone has any suggestions whatsoever about how I can get my backup data restored it would be greatly appreciated. After spending some time with MIUI - in particular the Galnet ICS build - I have nothing but praise, but I really have to get my data back!

You should be able to downgrade through ROM manager. Go to "All Clockwork Mod Recoveries" and just flash one that is not 5.x.x. Any backup not made with version 5 will not work with the new version So if you can flash one that is version 2, 3 or 4 you should be good to go. If that doesn't work you can fastboot flash it. There are guides on how to do that.

Wait.....did you mount /system before installing the CWM zip ?

Sorry for the delayed reply, for some reason I didn't get an email notification that my thread had been updated.

For some reason, when I select "All ClockworkMod Recoveries" the only two options are 4.0.1.4 and v4.0.1.4. I'll have to look into "fastboot" flashing as I've never heard of that.
By the way, if I boot into CWM via ROM Manager the version that loads is 4.0.1.5, but if I perform the three-button combo when switching my device on I get version 5.0.2.6.

I didn't, is that something I should try?
Edit - Just tried this and at first it rebooted CWM and the version number hadn't changed. Doing this again yielded me the following error with no change in version number :
Code:
E:Error in /sdcard/CM V 2.5.1.2_update.zip
(Status 0)
Installation aborted.

I found out that I can extract the contents of my backed up .img files using unyaffs.exe.
Unless I'm doing something wrong, it would appear that my backup is corrupt somehow. When trying to extract data.img, it processes for a while and does bring back a lot of files but I also get the following :
Code:
read image file
: Bad file descriptor
read image file
: Bad file descriptor
data.img is around 1.2GB but the files I extract only amount to around 190MB.
It would appear that I don't have my contacts database in there which is annoying as for some reason there were quite a few that didn't get synced to Google's servers.

[Q] Infuse zip flashing stuck at "Finding update package"

Hi guys, this is the first post i upload and want to take the occasion to greet you all.
In these days i bought a Samsung Infuse 4G...i really like this phone but want to be able to use it with some special features such as connecting various USB devices to the phone and other juicy stuff.
I read that the builtin ROM is not capable of such this thing, and Ice Cream Sandwitch, witch should allow to do that, is not available for this smartphone model. At least not officially.
My choice fell upon CM7 LinuxBozo ROM ( http://forum.xda-developers.com/showthread.php?t=1311960 ).
I rooted my device. I'm sure of that because i am able to use the root explorer with root privileges and the root menu shows up among my applications.
I then followed the instructions here ( http://forum.xda-developers.com/showthread.php?t=1107881 ) in order to install the ClockWorkMod Flashing Menu but I am not sure whether anything went allright or not as, after trying both the methods shown on the guide, nothing happened (in the first case, the automatic install through ROM Manager seems to work, a message appears on the screen confirming anything went smooth but when i reboot i see the normal reboot menu, no advanced menu nor CWM menu; in the second case i tried to manually load the CWM menu by placing the update file in the SD and renaming it to update.zip, the update gets stuck somewhere saying something about a bad or wrong signature, tried it a few times and with different CWM update versions but nothing to do).
I then stumbled into a workaround to fix that issue by an even more manual procedure ( http://www.youtube.com/watch?v=PkMo8rBehHg&feature=related ) basically consisting in copying the "recovery" executable from the CWM update archive to the directory /system/bin and of course chmodding it to rwxr-xr-x and chowning it to the root.
Now the CWM screen appears but, as i attempt to flash the CM7 ROM, the flashing gets stuck at "Finding update package". I read here ( http://forum.xda-developers.com/showthread.php?t=821499 ) that it could happen sometimes and it's just a matter of trying and trying again... I tried at least ten times up to now but it keeps getting stuck...maybe it's not my case.
Hope someone will help me out...i really need that USB reading feature. Thank you.

what color is your cwm screen?
this may be a simpler way of gettin cwm:
http://forum.xda-developers.com/showthread.php?t=1220090
specifically, the CWM instructions set.

I see that the instructions you suggested me would mean to start the process almost from scratch. I will do that as soon as i finish studying the nazis for my school report .
And maybe after getting the next answer from you
The boot screen is green text on black backgroud.
Holding audio and power buttons for 10 seconds doesn't prompt me to the red boot screen if it was what you meant and if I read the instructions provided well (witch i didn't as i have no time now)... don't get me wrong. Just trying to provide you as more information as possible.

if you still have root, download from market
sgs kernel flasher and the flash the gingerbread kernel to give you RED recovery and flash the rom of your choice after a factory reset and usual wipes

Cool... i'm now running CM7 !
Here is what i missed for anyone who would have the same problem in the future (you can find the download links here: http://forum.xda-developers.com/showthread.php?t=1220090 ):
CWM Installation Instructions:
1) You must be rooted.
2) If you have a /Voodoo folder on your internal SD card, delete it and reboot.
3) If you're already running a custom ROM with Voodoo lagfix FULLY enabled, you can skip to step 7.
4) Download CWM-community-kernel-v8.zip if you're on Froyo or CWM-infused-v2.0.1-kernel.zip if you're on Gingerbread and place it on your internal SD card.
5) Install SGS Kernel Flasher from the Market.
6) Open SGS Kernel Flasher, select choose kernel, select the file you downloaded, and select flash kernel. Your phone will reboot and begin to enable Voodoo lagfix. Let it do that and boot all the way up. It will take a while (5-10 minutes) because it's converting all partitions to ext4.
7) Download update-infused-v2.X.X-full.zip and place it on your internal SD card.
8) Power off your phone.
9) With the phone powered off, hold both volume keys and the power button for about 10 seconds and then release. This should boot you into RED CWM.
10) Select "install zip from sdcard" and select update-infused-v2.X.X-full.zip.
11) Once that finishes, select "wipe data/factory reset".
12) Select "reboot system now".
13) Do NOT restore system data with Titanium Backup. Do NOT restore ALL apps with data. If you absolutely must restore something with Titanium Backup, only restore MISSING apps with data.

Now just another question: i noticed different errors when running the market and other old built-in apps... I just need to reinstall gapps right?

yeah, that is why it's stickeyed.
you just had to read/search them.
market wise, there's a market fix
or you can also factory reset and wipe cache and dalvik in cwm

Thanks. You helped me solving this and now anything works fine. Have a good day.

I tried different versions of gapps including the one suggested in the CM wiki but with no luck. I guess the problem is somewhere else.

[Q] Trying to Root: hboot 1.45.0013, Unlocked Bootloader, S-ON

Okay, have found a lot of threads similar to this, but with key differences that are making the answers not-terribly-helpful in my particular circumstances. Not a comment on the answers, but enough that I feel the need to ask my question specifically.
I am trying to gain more control over my MyTouch 4g Slide (aka Doubleshot), obviously on T-Mobile.
It is running Android 2.3.4, and has hboot 1.45.0013. I have wiped it a few times in the process of fuxing with it, so right now I'm not worried about losing anything other than basic function (i.e., bricking it is still bad).
I have tried the zergrush exploit (it's been closed),
have managed to unlock the bootloader using the HTC unlock tool,
and have managed to flash the appropriate Clockworkmod recovery and get the blue menu to come up.
My overall goal isn't to do any major overhauls- I want to be able to allow some apps to turn my GPS on and off, clean out some bloatware, and put some new ringtones into the same folder as the stock ones. My understanding is that temporary root access is enough to do these things- go in and clean up, change some permissions on apps, then go back to being a normal user, just like with a well-managed Linux computer.
I just can't seem to get the next step to work.
My understanding is that I now somehow use Clockworkmod to install Superuser from the .zip archive. The options I get in the recovery screen are:
reboot system now
apply update from sdcard
wipe data/factory reset
wipe cache partition
install zip from sdcard
backup and restore
mounts and storage
advanced
power off
My impression is that I should be using "install zip from sdcard" to install Superuser, but when I select that, the menu just disappears, and I am left looking at the logo, with no further options. I have seen it implied that there should be choices about which zip to install- those never come up.
What am I missing? My google-fu is failing me in trying to find instructions or guides for this particular combination of limitations and progress.
EDIT TO ADD: Ah- found part of my problem... the recovery menu uses the camera button, not the power button. Still somewhat at a loss to see what's next. Installing from the SD card fails. Info in a second post.

Got the menu working, but now failing to install Superuser. I get the following output:
Mounting SYSTEM...
Deleting SYSTEM:bin/su...
Extracting files to SYSTEM...
Setting SYSTEM:bin/su permissions to 06755...
Creating SYSTEM:xbin/su symbolic link...
E:Error in /sdcard/Superuser-3.0.7-efghi-signed.zip
(Status 0)
Installation aborted.
Now what?

I am seeing in other places that HBOOT 1.45.0013 can't be rooted. I've been trying for about 9 hours to do this. . .no luck, even with a variety of methods.
bummer.

I'm in the same boat as the both of you. Spent the last two hours and enough tabs in my browser that my music player was skipping when switching between them, and my machine is nothing to be scoffed at!
There just doesn't seem to be enough clear information about how to root this device, and with only 7 pages of development threads, it's gonna be hard to be told to search!

In recovery you use the trackpad to navigate, and select....also, why not just flash a pre rooted stock rom? Follow the directions in this thread, it will work with any rom, not just ICS roms. I used the instructions in this thread to install Bulletproof on my Bf's phone which was an insurance replacement, so it had the same hboot that you guys have, and S-on. It worked flawlessly, I am not sure why so many people are having such a hard time, because it worked the first time perfectly for me.
http://forum.xda-developers.com/showthread.php?t=1508556
Edit: Which recovery are you using?

Woot! Oops...
Well, I managed to root my phone... and then borked it through my own overexuberance. :headdesk: Oh well, I can fix it. Important part:
I finally found out what "Status 0" means- the zip you are trying to install wasn't signed properly. I re-downloaded, no luck. But there is an option to turn off signature checking in CWM, and that worked, after some fiddling- Superuser installed and worked fine. Not sure if re-downloading ended up being relevant or not.
So, you can root this version without flashing a new ROM.
That said, I think I probably did enough weirdness to mine that I will go for a new stock ROM, so much thanks to yellowjacket for posting that thread link. Removed HTC Sense, then somehow borked Go Launcher Ex, so my phone doesn't have a home screen and I can't get to the app I used to move stuff to fix it. Of course I never found a set of instructions for making a Nandroid backup until after I messed things up... Oh, well, time to go looking for the stock ROM.
Thanks all!

If anyone has a Nandroid backup or copy of the dead-standard out-of-the-box ROM for this phone, please let me know. All I am finding is modified versions. Can't find the base that they were made from, and even the most basic version says it requires S-OFF to install. :headdesk:

Do you specifically need a nandroid backup, or would a flashable ZIP do? Pointers to the latter are available.

Flashable zip would actually be preferable, and pointers would be very much appreciated. I know they have to be out there somewhere, I'm just not finding the right search terms to locate them among all the modified versions.

Look at this post in the developer reference thread: http://forum.xda-developers.com/showpost.php?p=17384145&postcount=7
(There's lots of stuff listed there, but look for the 400 MB+ images.)
NOTE: Some ZIP tools get confused by these signed ZIPs, so they might seem corrupt. Check the MD5s to see that you got a good download. 7Zip seems to deal with them OK if you want to look inside.
I have personally flashed the 1.28 and 1.55 ZIPs without incident, but I did check the MD5s.

Well, I was not able to restore the ROMS from the links wjcarpenter linked- everything worked fine, as far as I can tell, but the phone said the "updates" were older than what was originally installed, so the installation was aborted. Not sure how to fix/handle that.
For the moment, I have one of the cleaned-up ROMs that is very similar to stock, but I would really rather it not be obvious that I rooted the phone the second you start it up (the one I found has changed the startup animations), so I will keep looking.
If it's going to be obvious that I changed the ROM, I guess I might as well start looking for the best custom ROM... any suggestions as to which is the most stable?

Just think of it as a big learning experience! The first time I rooted a phone, I messed it up so much I had to keep flashing back to stock and rerooting at least 3 or 4 times. Thankfully I had a phone that was virtually unbrickable. It was a good learning experience though, and I now feel comfortable rooting and flashing on several different devices.

Lenovo IdeaTab a2107

Hello everyone,
I bought this tablet on ebay and it seems that the ROM preinstalled is a test ROM.
I searched the web to find a custom ROM but I couldn't find much info.
I found the way to root the tablet but that's all.
Is there anyone who can indicate me a link to a stock rom or a good custom one?
Thanks for those who will read and help!

What do you mean by TEST ROM?!!! this is ridiculous, I have the tablet and it's working like a charm even I received over air update yesterday, the only odd is that I can't use it as a phone because Lenovo has no license yet for that it's available only in the Chinese version, and I think this will be solved later when they start launching their mobile phones all over the world.

Hello mmis,
Test rom is not the correct terms but I didn't know how to call that !
The problem is that every widget I put on the desktop is loading but never display anything.
The information in "About tablet" are the following :
Model number : IdeaTab A2107A-H
Android Version : 4.0.3
Baseband version : MAUI.11AMD.W11.50.SP.V13, 2012/05/25 01:09
Build number : A2107A-H_S307_120605
If I search for system updates, it doesn't find anything. If I click on firmware update, the settings FC.
I made a factory reset but no luck.
That's why I thought it wasn't a stable version.

As long as you tried the factory reset with no luck, I think in your case its better to get back to Lenovo customer service or your local dealer if it's under warranty, they should be able to help you. it's a new device in the market and it will be difficult to find custom ROM for a while or even someone to give model-specific help. Good Luck

Would you mind linking to the instructions on how to root this thing?

Sure, no problem !
After several hours of search and difficulties to register onto Chinese websites
I managed to find the attached file. I take no credit for the tool because it was developped by someone else (SNARL I guess)
It was missing the superuser apk inside so I put it back and also translate the steps to English.
Here are the steps :
- Connect the tablet in Debug USB mode
- Launch root.bat
- The device will reboot at each of the 3 steps
If you need more info, don't mind to ask!
Here is the link of the original thread :
http://3g.lenovo.com/thread-69003-1-1.html

Fantastic, thank you very much.

LePad Chinese Model A2107A-H
I have a Chinese issue model of the A2107A-H that has the dual sim card cellular feature. I've been trying to get it rooted to get rid of the Chinese apks on it, but normal rooting software has not been successful so far, including the one posted here from SNARL via Ichi go's post. I get a "device not found" error message and in device manager on my PC it indicates that there is no driver installed for the device. I have "debug" turned on and the USB link seems to be working as I can see file folders on the device, but the rooting software will not run. I've tried several of the most well known methods with no luck. Any ideas on this would be appreciated and in particular, if there is a driver I need to have installed to get the rooting software to work??
TIA!!!
Rob

First of all many thanks to you ichi go it was very easy to root this device as instructed, but as the one I have does not have the phone calling capability, I replaced the phone.apk with different one but now the device does not recognize the sim card at all, I tried to push many versions of phone.apk to system folder with no luck, it seems even if I put the apk in the system folder the device will not launch it at all, could you please help me in that.

I've had this tablet for a while and love it. I just got the OTA update and its downloading now.
I'm a also keen on rooting it and inns installing a custom ROM. I guess once its a bit more common, we can expect a dedicated Dev community here on XDA

The update failed to install. I'm not rooted or anything but upon restart it gave a signature verification error.
Any way to fix this?
Edit: got it! was a path error since i had changed the default storage.
but i can't figure out any changes

I get a "device not found" error message and in device manager on my PC it indicates that there is no driver installed for the device. I have "debug" turned on and the USB link seems to be working as I can see file folders on the device, but the rooting software will not run. I've tried several of the most well known methods with no luck. Any ideas on this would be appreciated and in particular, if there is a driver I need to have installed to get the rooting software to work??
TIA!!!

How does your device appear in the device manager? For sure, the adb driver isn't installed. If it's not the case, download android sdk and then the Google USB driver in the extra section.

First of all many thanks to you ichi go it was very easy to root this device as instructed, but as the one I have does not have the phone calling capability, I replaced the phone.apk with different one but now the device does not recognize the sim card at all, I tried to push many versions of phone.apk to system folder with no luck, it seems even if I put the apk in the system folder the device will not launch it at all, could you please help me in that.

FM Tuner - perfect for in-dash?
The in-dash car tablet people should be happy to hear the A2107 has an FM Tuner. It's one of the few tablets that has a radio tuner, and the only modern 7" that I know of. I just ordered one. I will report back.

The Chinese stock rom I installed has the phone ability and that works very well! The problem of this stock rom is that the Google services aren't there. I'm trying to find a way to install the zip file but I need to know the exact path of the recovery partition.
I tried to find it with the cat /proc/emmc command but this partition isn't listed.
If anyone has an idea...

So I understood that you managed to flash the Chinese stock ROM, am I right?!! please tell me how to do as I am facing serious problems with my device, I managed to root and then I changed the phone.apk (what the hell I was thinking of) and now I have the the error message android.process.acore stopped working and sometimes the sittings force closed, I tried to re root, factory reset and deleting cache of almost everything with no use, even I contacted the Lenovo CS to reinstall the original firmware, I think they will charge me for that :crying:
by the way I don't have contacts anymore (I installed it manually) and the most impressive thing that the device doesn't recognize the SIM card (I cleverly deleted the original one phone.apk :silly and what ever apk I push into the system/app folder and change the permissions it will not install after reboot.
So...what do you think guys?!! any help?

I've confirmed this does work on the A2107-F.
I had some trouble with the ADB driver. I can't post links, so you will have to google it, but I used adb_driver_20110720.zip for the drivers. I forced it to install via Update Driver > Browse my computer > let me pick > have disk > pointed to the android_winusb.inf file > selected the thinkpad option, it was the bottom of the two.
I also had to manually turn the tablet back on after the first reboot, but it went fine after that.

Btw, I managed to install all the Google services and all is working well! The only thing is that the OS can only be put in English. All other languages are Chinese variants.

[Q] Unable to install GApps on Maxell C8 with ICS

Hi all,
I'd like to politely ask for your help with adding Google Play to my friend's tablet which unfortunately doesn't provide this app in factory setting.
First of all I'd like to mention that I've searched here before (and other sources over the internet as well) and found many threads with similar issues. Still I was unable to get everything working because of some problems that I'm not able to solve as I'm still just a user... Unfortunately it seems that each device is unique and requires a little different stuff to reach the goal.
So here's some basic information about the device:
Maxell Maxtab C8
Android 4.0.4
Kernel version: 3.0.8+
Here's what I was able to do so far:
Successfully rooted the device
Successfully set -rw to /system (using the "Mount /system (-rw / -ro)" app
I've tried many various Google Play installers including:
Android Market_install_files.zip
PlayStore_v4.6.17.apk found somewhere here in the forums
And about 5 more other without any success. Result is that Google Play is there but it doesn't work - I mean the icon has been added, Gmail account has been "assigned" to it during its first run and then every time I try to run Google Play there occurs an error saying that "Google Play stopped working" and it simply won't run. I also tried the simple solution with "Android-Market_install_files" package (4 apps) - as I found out it's the official way how to use Google Play on devices where it's not preinstalled. Still it didn't work as well - again ended up with the same error (stopped working). But there is maybe some kind of problem with the installation because two of four .apk files included in the "Android Market_install_files.zip" package cannot be installed as the device tells me that this app cannot be installed because of the conflicting signature (I found more about this here: http://stackoverflow.com/questions/...g-package-by-the-same-name-with-a-conflicting). I'm using files signed by Google. Advices are to firstly uninstall the original apps and then install these but I'm not able to uninstall as I can't find them. Guess these are some kind of system apps and I'm not sure where to find them exactly. Still no luck even using Root Explorer. These apps are called "OneTimeInitializer-signed.apk" and "GoogleServicesFramework-signed.apk". I think maybe Google Play from this package could work but the problem is caused by the device which doesn't overwrite the original apps (because of the signature).
Currently I've also found GApps Manager (http://forum.xda-developers.com/showthread.php?t=2589167) - I think this might work but I'm not able to test it at all. Simply I can't find how to get this Maxell tablet into recovery mode to find the "install from zip file" option.
Interesting is that there is no "Phonesky.apk" file in the device's memory...
Sorry for my post being soooo long but I'd like to provide as many additional information as possible.
Could you please give me advice how to install GApps on Maxell Maxtab C8 device or any other solution?
This could look easy for many of you but I'm working on it over two weeks now and I'm really clueless, even more when there are users confirming that Google Play works with this device. So I hope you're be so glad to help. Any help will be highly appreciated! Thanks!
With kind regards
PJ

Some info, since you have root, you can simply move .apk to your /system/app folder.
Also you had stated there is a conflicting issue with the same type of signature, this is because there is already an existing file of the same source.
To uninstall this .apk it usually located in the following folder(s).
- /system/app
And
- /system/priv-app
Just select and delete it. Reboot the device. And move your new files into /system/app and reboot. Make sure you also move Ann app called "Google Play Services.apk or GP will not start
Great things come in small packages.

Re:
Hi krishneelg3,
many thanks for your answer. Your advice looked really easy and reasonable but it didn't work.
I deleted all required .apk files from /system/app. Maxell tablet doesn't have /system/priv-app folder. Then I copied all the GApps files to corresponding folders in the tablet (/system/app, /system/etc, /system/framework, /system/lib). Then the setup wizard started but when I tried to confirm the setup guide touching the green Android icon it did nothing. After restarting the tablet I didn't see the setup wizard app any more. Tried about 5 times in a row from the beginning (copied the original files from the backup back to tablet, then replace them with the new ones from GApps) and always ended up with the same result.
There's also META-INF folder included in the GApps package. It seems to contain some certificates but I'm not sure what to do with it or where to copy these files. Could this be causing the problem?
Thank you very much.
PJ

I would like to tell you that, the GApps package is supposed to flashed via recovery.
The META INFO contains scripts to install and also certs
So if you have a custom recovery available for your device flash the custom recovery img and if you already have it then just flash it via recovery.

Sorry for the delay... I didn't manage how to switch the device to recovery mode. I tried many solutions reported to work for this device but they didn't for me. Some tested, some not because apparently my knowledge is user-level. To be honest after over 3 weeks trying I gave up.
But thanks for your effort.
Regards
PJ
