Help my Sero 7 pro stopped working
« on: May 25, 2015, 10:42:20 AM »
Hello all:

Never dropped our Sero 7 pro, worked fine until yesterday plugged it in to recharge, saw the charging icon and left it alone.

This morning it won't turn on at all.  Tried every button combination and nothing.  Nothing working at all.  Any ideas?  Charger works on my Note 3 and other devices.

First thing that comes to mind,  maybe it got bumped. Pet pulled the cord. Something of this nature,  just enough to loose contact with the port. Try charging again.

Take a close lookmat your charging port. Over time it may have become loose.

Hello again Laura, So great to still see you here, helping all us clueless guys...
This is Rami, you helped me a lot back in October with my Sero 7 Pro.

I know this is not the right Forum, I could not find it, I found you here "Lucky Me" :)

In any case, I hope you can help me again. I turned on my tablet yesterday, it booted in A strange way, still through the Liquid Smooth. Most of the apps disappeared (out of about 40 apps I had only about 8 left). Those that were still there did not work properly. Tried to restore my system through recovery, this did not work either, tried many times with different options - Nada !!
All the apps to check if the tablet is rooted, Rom Toolbox and many other useful ones were no there. So, I started everything from scratch again (using your tutorials) - Rooting, installing the Clock mod recovery, and finally installing the Liquid Smooth ROM. All went well. Restarted the tablet, went through the LS boot and to the main screen. Luckily, the Google Play app was still there. So, I prepared a list of all the apps I was planning to reinstall, starting with the Rom Toolbox Pro. I downloaded it from Google Play, and when it was trying to install it, low and behold... came back with the dreaded "ERROR - INSUFFICIENT STORAGE AVAILABLE" (I CHECKED THE BUILT IN MEMORY, THERE'S MORE THAN 3.5GM OF MEMORY AVAILABLE), WHICH,  AS YOU MAY REMEMBER STARTED THE WHOLE THING AND THE REASON I ASKED YOUR HELP FROM THE START...
CAN YOU PLEASE HELP, ANY IDEAS, SUGGESTIONS, I Am LOST???[/color]

Further to my entry above, I did a factory reset, installed the CWM recovery and then installed to the apps I needed - all worked great. Finally, I also flashed the Liquid Smooth ROM. After doing that, my Google Play Store stopped working. Nothing I tried (from suggestions online) helped.

Can anyone please help??

Thanks

Hello Shneor,

Thank you very much for your reply.
You suggestion worked great. My mistake was that I was trying to install the Google Play Store by itself, now I know that this does not work.

BTW, I noticed that next to your name it shows your device... as "Sero 7 Pro, LiquidSmooth, OC, CWM...

What does the OC stand for and why is it good to have it? (:

Thanks
Rami

Hello again Shneor,
Thanks for your reply and explanation..

I have not done any upgrades to my Sero 7 since about October 2014.

Back then I flashed the CWM based recovery, (v6.0.4.5) and also the LS (Liquid Smooth) that upgraded my device from 4.2 to 4.4.

Is the dopa 5.1 an upgrade similar to the LS that upgrades to the Android 5.1 OS?. What are the advantages to have this upgrade done??

If yes, can you please let me know where I can get if from so I can also upgrade mine?
Any special instructions to flash it?, do you flash is on top of LS?
Do I also have to upgrade to a newer version of the CWM?

will this have any effect on all my existing Gapps, backup and restore??

Can you please help me with all this??

Thank you very much and best regards

Rami

Hi Rami,  if you would like to try lollipop you can find the link here,  at the bottom of the list.

http://sero7forum.com/sero-7-root-hack-mod-and-development/custom-roms-for-the-sero7-pro/

You will first need to flash philz recovery. it's at the link for lollipop.

Follow the developer's instructions.

FIRST use CWM to make a backup of yohr liquid smooth. Make sure your backups are stored on the external sd. Keep the CWM zip there also.

That way if you don't like lollipop,  you can boot to philz recovery, wipe cache & dalvik cache,  flash back your CWM recovery,  reboot recovery, wipe data,   flash your nandroid backup,  reboot system. you're back to liquid smooth. (Then you'll be a flashing expert! :)  )

Hi Laura,
Good to hear from you again.

Regarding your reply / suggestions, please see my questions, comments in your text below..

Thank you very much for your help..

JUST TO BE SURE - NO NEED TO REMOVE ANYTHING FROM THE EXISTING STUFF, JUST FLASH THE NEW RECOVERY OVER THE EXISTING ONE?


Follow the developer's instructions.

FIRST use CWM to make a backup of your liquid smooth. Make sure your backups are stored on the external sd. Keep the CWM zip there also.

I MADE A BACKUP OF ALL MY APPS USING ROM TOOLBOX PRO, AND SAVED IT TO THE EXTERNAL SD. NEVER DONE A "FIRST use CWM to make a backup of your liquid smooth.", CAN YOU PLEASE EXPLAIN WHAT I HAVE TO CHOOSE AFTER BOOTING INTO RECOVERY?                                       


THANKS
RAMI

Hi Rami,

Yes, just flash Philz zip file right over CWM.  the zip will over ride CWM and replace it with Philz.

It's great you backed up your apps and data with ROM toolbox.   But the benefit of a complete backup - aka Nandroid - is EVERYTHING is backed up.  EVERYTHING meaning the entire ROM including all your settings, downloaded stuff, ect...... EVERYTHING.  So you're back to actly the same ROM from the moment you created your nandroid. 

So if you don't like lollipop, you can flash that nandroid of your liquid smooth and you don't have to start from scratch setting up all your settings, or adding your apps you backed up with ROM toolbox.  Just flash the nandroid (sometimes referred to as nand) and you're done.

For making a complete backup -   I have a tutorial just for that!   ;D  Your CWM might look different from the one in the tutorial, but it's done the same way...It's done pretty much the same way no matter what custom recovery you are using.  Although sometimes the wording is a little different...

Hello Laura
Thank you very much for your continued help and support with my Sero 7 upgrades.

Regarding: "But the benefit of a complete backup - aka Nandroid - is EVERYTHING is backed up.  EVERYTHING meaning the entire ROM including all your settings, downloaded stuff, ect...... EVERYTHING.  So you're back to actly the same ROM from the moment you created your nandroid. "

I created the Nandroid as per you tutorial - All went well !!!

Also, flashed the Philz recovery ROM - and that turned out OK as well. I like it a lot, it's much more more elegant and user friendly than it's CWM predecessor...


Now, regarding the upgrade to the Lollipop, do I just flash the "sero7pro-aosp510-dopa5-v1.1.zip" ROM, and that's it?

After doing that, I'll have to create another Nandroid based on the new system, right?

THanks

Rami

Hello Laura
Thank you very much for your continued help and support with my Sero 7 upgrades. You're welcome!

Regarding: "But the benefit of a complete backup - aka Nandroid - is EVERYTHING is backed up.  EVERYTHING meaning the entire ROM including all your settings, downloaded stuff, ect...... EVERYTHING.  So you're back to actly the same ROM from the moment you created your nandroid. "

  Yes, and TWRP has it's own look also.  Which I like a lot.  One day for kicks, you should flash it.  And see it.  It has very large buttons.

Now, regarding the upgrade to the Lollipop, do I just flash the "sero7pro-aosp510-dopa5-v1.1.zip" ROM, and that's it?  No.  There are several steps to take, as you are not flashing over another custom rom from the developer or a CM based rom. (I don't think liquid smooth is CM based anyway) It looks like a lot of instructions, but they are easy, you will be able to follow them, I am confidant.  Don't look at them and be intimidated. 

In a nut shell you will be:

Making another nandroid with philz recovery (good to have, as you like it and can keep philz.  Your CWM nandroid may not flash in philz. (not sure) ) BE SURE IT'S ON THE EXTERNAL SD.  THE INTERNAL STORAGE IS ERASED DURING FLASHING OF THE ROM.

download the ROM zip file(full rom) and the pa_gapps nanno package for lollipop zip onto your external sd card.  Also, the nexus7 spoof zip if you want it.

boot to recovery
wipe
install all the zips in this order - rom, gapps, spoof.
reboot system. x2

happy happy joy joy! if all went well.......

Follow the developer's instructions for all the details on how to perform each step using philz.  Follow instructions for "FIRST TIME USERS "  Click "click to show" and start at step #2, as you already have Philz.





After doing that, I'll have to create another Nandroid based on the new system, right? Yes!

THanks

Rami

Hi Laura,
Many thanks again...
Regarding "yeah! Now you're an expert. " - not there yet.. but thanks... funny  :),

Just created a new Philz based Nandroid.

Doesn't each new Nandroid created, on top of another existing one, use quite a bit of the SD's storage space, what would be a good size of an SD to prevent it from running out of space?

During all this Nandroid creation, what happens to the "Link2SD - do I have to re-establish the links again or they're preserved??

All this upgrading, Rom flashing, Nandroid creating, Gapps downloading etc.. is really exciting and there's a lot to be learned. Yet, there's also a downside, for me at least.  With each wipe, I lose all my personal Apps (I have about 15 of them), this requires to reinstall each one of them manually, re-establish all the login id's, passwords etc..

Any comments, ideas for short-cuts... would be appreciated??

I'm also very amazed with the resiliency of this tablet, after almost 3 years since it was introduced, developers are still writing software for it... Just wondering, are there any other tablets with this kind of success and following?.

All comments would be appreciated...

Thanks
Rami

Hi Laura,
Many thanks again...
Regarding "yeah! Now you're an expert. " - not there yet.. but thanks... funny  :)YES you are!

Just created a new Philz based Nandroid. great!

Doesn't each new Nandroid created, on top of another existing one, use quite a bit of the SD's storage space, what would be a good size of an SD to prevent it from running out of space? Yes.  The Sero7 supports up to 32gb.  I suggest that you use that size.  Although some people are using 64gb sd cards, the tablet doesn't support them.  What that means is... you COULD loose data.  Probably not, but you COULD.  So probably not the best place to store nandroids.  Unless you are willing to take the risk and don't care.

You can also store your nands on your PC in a folder somewhere.  But, keep in mind copying and moving them back and forth could cause corruption.  Usually not.  But you know that Murphy guy!!  So always have a backup of your backup.  :o If you're moving them around.  I actually have an SDCard just for nands.  I keep one on my tablet on the external sdCard, and have others on an SD just for nandroids.  For a few different tablets, and a few different ROMs I liked.  When I get bored, I can swap them out.  Or if someone asks me a question and I just can't remember if it's important enough I'll flash it and see.  After a while I purge the older ones.  Make room for more!!  ;D

During all this Nandroid creation, what happens to the "Link2SD - do I have to re-establish the links again or they're preserved??   See post #18 in my tutorial here: http://sero7forum.com/sero-7-apps/links2sd/15/

You slide the left side out and clink to re create the links.

Don't forget to clean up the 2np partition occasionally.


All this upgrading, Rom flashing, Nandroid creating, Gapps downloading etc.. is really exciting and there's a lot to be learned. Yet, there's also a downside, for me at least.  With each wipe, I lose all my personal Apps (I have about 15 of them), this requires to reinstall each one of them manually, re-establish all the login id's, passwords etc.. As far as your personal apps go..  I thought you said you were using ROM toolbox?  You can restore all your apps and data with your backup from the toolbox- There is a batch function with the tool box.  BUT please note:  sometimes restoring data from one ROM to a completely different ROM (not updating though) you can have issues.  So if you do, and have an issue, you will have to uninstall and reinstall that one app without including the data. (and that's a debatable topic for some people.  But, many do say some data in your app is ROM specific.  So having it there in another ROM may interfere with performance.)  Anyway... use the batch function! Select them all and then install them all... 

After flashing your new ROM and setting up the tablet, install the toolbox, (from google play or your backup folder, you'll find the apk.file there) open the toolbox, go to preferences and change the preference to storage>external>apps backup.  Your previous backups should load into the app.  If they don't load, reboot the tablet.  They should load. (if not, check the path to the backup and correct the location)  Then choose the apps you want to flash onto the tablet - use the batch function - and flash them all on.  with or without your data.  Your choice.

Just wondering, are there any other tablets with this kind of success and following?.  We are incredibly lucky to have DoloresPark behind us and our tablet!!!
