Hello.

I allow myself to report a request that I did in the other threard on the tablet and Android M. Perhaps more people pass here and someone will help me to solve my problem.

Thanks in advance.

Good evening everyone.

I hope you can help me with a problem with the boot of the tablet

- (tab2 model A10-70L), build number: A10-70L_S000214_170606_ROW

From when I switch it on to when it becomes operational it takes exactly 10 minutes to start.

10 minutes and zero seconds .. I can not explain it to me.

How can I reduce this delay? With Lollipop the start never gave me any problem: now with Android 6 and with the root (magisk, v.16.4) I have this inexplicable behavior.

Can you tell me that the problem is born?

Every help is more than welcome

Thank you

Luigi
[Android General] bigrammy:
First time boot of a fresh install takes 10 mins this is quite normal.

After a few days and a few restarts this will dramatically reduce.

From FULL OFF to my Lock Screen showing with WiFi connected takes exactly 34 seconds.

I am using My own custom stock rom which is posted in the other thread and it's rooted with SuperSU.
[Android General] luighigno:
Thanks for the reply.

in your opinion, what does that behavior depend on?

I saw that installing magisk from twrp the boot is back again very long.

Hello
[Android General] bigrammy:
Use SuperSU and compare the startup times :confused:

I have Magisk installed on my other devices and have not noticed any unduly long startup times but things may be take slightly longer while Magisk runs it's scripts and handles all the app processes executed at boot up.

Are you using Xposed??? If so that's likely the cause.
[Android General] Jammol:
Hey Big,

Do you know where it is I can find internal parts for sale for this Tab 2? Need to find a new battery for my aunt.
[Android General] bigrammy:
Really Jammol you need me to search ebay for you :laugh: :laugh:

Since I am bored here you go https://www.ebay.com/itm/New-Genuine-L14D2P31-battery-for-Lenovo-TAB2-A10-70F-A10-70L = $20 USD

OR Amazon (USA) https://www.amazon.com around $27.00 USD
[Android General] Jammol:
My apologies. I phrased my post wrong. I know of sellers on eBay and Amazon that provide the parts. What I should have typed better was if you had any of them that you have gotten parts from or who you could recommend. ? I was in a rush when I typed that post at work. My apologies again.

Jammol
[Android General] bigrammy:
:laugh: No problem Jammol I thought it was a little odd :silly:

But to answer your question I have not had to purchase anything other than the flip case so I am afraid like everything on ebay it's a bit of a gamble.

I would use Amazon and pay slightly more because Amazon don't normally quibble plus it's seems to ship from the USA rather than China. :o

https://www.amazon.com around $27 USD
[Android General] Sparkrite:
Hi all,

Long time no type, and all that. :)

Anyway here's an odd one, was using a spurious charger while away on holidays, all was well until one day the tablet will not charge while turned on, but knock it off and it will charge properly. Was blaming the spurious charger but upon returning home it is the exact same with the original charger. Any ideas please?

Personally I suspect a hardware fault, unfortunately.
[Android General] bigrammy:
Hi Sparkrite,

Only just spotted your post and you have probably worked out what the problem is by now. :confused:

I think this could be software problem rather than a hardware issue as the battery charges normally while off. :eek:

Maybe a full wipe is in order as the spurious charger may of logged up some bad battery stats by overcharging or over volting the battery.

Hope you get it sorted. :fingers-crossed:
[Android General] charlestek:
The stock charger has a hard time charging the tablet quickly with the tablet on, as the current draw from the tablet running plus the current required to charge the battery is close to what the oem charger

can source. Other than having a bad cable (assume you swapped cables), the only other thought would be that perhaps you have a lot of power hungry apps running all at once with the tablet on and that is slowing the charge-up. You might try installing the Ampere app from the play store and see what kind of current the tablet draws when it is on and charging. I have a inline ammeter (somewhere) and can also tell you what my tablet draws when charging with the OEM charger.

As I think about it, the most likely culprit may be the solder connections for the female mini usb jack in the tablet becoming loose and therefore causing problems with supplying current into the tablet.

The jack in my Tab 2 managed to break off one day when I dropped the tablet slightly with a power cord attached that jarred the connector with too much force.

Fortunately I had a Square Trade warranty and was able to get it repaired.
[Android General] Sparkrite:
Hi [MENTION=3924647]bigrammy[/MENTION], yeah I worked out what the problem is alright :( and as suspected its hardware .

Tablet not seen by PC when connected either on/off, TWRPed back some earlier images and no change so cannot use SPflash to FULLY re-set tablet as not seeing preloader.

I have opened and disconnected battery and checked all connections around USB port but to no avail unfortunately.

Wont even charge in TWRP but will charge fully when off.

Ah well, we live and learn, thats the second one that "fried" from using cheap chargers, the first from a crap car charger.

All well with you and I'm sure you are settled in your new home by now.

Cheers.

[Android General] mkfsf2fs:
Hey,

I have stumbled across my old Lenovo Tab 2 which I had lying around for some years.

Last thing I did was trying to repair the WiFi Antenna which worked quite well.

Unfortunately I slipped when soldering and removed 2 SMD parts from the WiFi transceivers input circuitry -.-'

I was hoping to find some schematics of the tablet's pcba to get the type and values of the parts...

Unfortunately I was out of luck and let it rest.

Since I did not seek help here yet, I just wanted to ask whether anyone might have a clue what those SMD parts could be.

[IMG="Image indicating the SMD parts."]https://i.postimg.cc/Y9JkJjYr/lenovo.jpg[/IMG]

Any idea what it could be?

I remember I looked up the Ref Manuals of the transceiver but it did not help...

If I'd be guessing I'd say its an input RC-filter or RL-filter but still I don't know its nominal values.

Any help would be greatly appreciated :)

(or pcba schematics)

Best regards

[Android General] bigrammy:
Hi,

Have a look at this one Here hopefully it's got the info you need. :fingers-crossed:

Thank you very much! I will look into it. On first sight it looked quite promising. I'll let you know how things worked out :D
[Android General] mkfsf2fs:
[MENTION=3924647]bigrammy[/MENTION] I have checked out the schematics but unfortunately they seem to be for a different PCB (using two distinct antennas instead of one)... I took a look at my tablet and the imprint said "A6602 MB PCB V3.0".

I probably should have done that in advance... -.-'
[Android General] bigrammy:
Yes it seems that the .pdf is for the earlier Tab A10-70 not our Tab2 A10-70 :(

Sorry about that I should of spotted the drawing date of 2014 which is before the Tab2's release. :silly:

Well back to the drawing board i guess. :o
[Android General] lazostat:
I have a question about what is the max speed this tablet can read through a sd card. How can i find this?

Also should i format the sd as internal or external disk?

I did a test with an app and these are the results. The write/read speeds of sd card are very slow, compared of the tablet's. I have an Sandisk Ultra microSDHC 32GB U1 with up to 98mb/s speed. So i guess the tablet sd slot can read these speeds?

When i format it as internal, there is no option to select it for test.
[Android General] htc_unenthusiast:
I have a Lenovo Tab 2 A10 70F. Recently I can no longer get it to power on. The bootloader and charge screen are find but I noticed the pad for the "PRWKEY" is ripped off the PCB. I don't see this pad leading anywhere beyond a testpoint but it seems like the power button is dead. Is there a way to test this problem? I would like to jumper around as a test if possible.
[Android General] dvasiliou:
I would like some help please. After reseting my tablet (stock rom, never made a change), after boot and when i am trying to set a google account (or go to play store etc) i get the message Unfortunately Google Play services has stopped. I tried the Resque app Lenovo has but A10-70L isnt there. I tried clearing data on Google services app (as i see on internet solutions) but didnt made a change. Is there a way so i can flash stock rom (or a rom that will work, i need only Netflix and Yourube). Thanks, if anybody can help.

[Android General] Jbrimb:
Try using the aurora store instead of the google play store. For this you need Fdroid (which is an alternative appstore for open source apps) you can install aurora from fdroid. This wont fix your issue, but hopefully you'll be able to download your apps anyway

[Android General] KenMH:
Hi,

Not sure if this is the right place to post this but I have a Lenovo Tab2 A10-70 that will only charge when connected to a computer. When connected to a wall USB charger the current falls off to about 0.01mA when the screen goes off but if I connect to the USB port on a laptop PC or even to a raspberry pie computer it charges at about 0.5 A. I tried reflashing to a stock ROM and then ran the updates back to Android 6 and the problem was still there. Any thoughts from anyone what else I could try? I have anothe identical tablet that I could clone from if that is possible. I am assuming that this is a software problem as it charges from a computer USB.

[Android General] Bleskerinno:
I hope I'm not late to the party but:

I've had this tablet since it came to Portugal in 2015. In 2019? I guess, it starting stuttering a lot and suddenly freezing and weird things were happening to it so I just stopped using it. Sadly did I know that was the first sign of this tablet giving me some headaches.

2 or 3 years ago I decided to finally fix this paperweight, has it has an amazing screen, either in size and resolution, and might serve as an awesome media center once again, but there's no way I can get it to work back at home.

I can flash the stock rock, 4.4.4 versions and it just "works"? As soon as it boots, while in the setting up workspace for the first time, it starts to give some flashy errors concerning gapps and Ui and things like that so, it just remains the same. After some reboots those errors vanish and I can use it, but no point in using such an older version on a good tablet like this one.

Moving fowards, I can flash the stock rom in 6.0 (MM), given by this amazing posts, but it just doesn't start! :( It boots but then just freezes in the main Lenovo logo, the one that burns your eyeballs :/

Last night I tried everything that says here. I tried to flash the custom recovery, from the post #6, did everything just as you guys said and the small pixel balls actually popped up! But it just stayed like that, the balls jumping and 30 minutes later it went back to the white screen :( So I guess it was a failure? TWRP worked and oppened in recovery mode, the magisk official file installed I think but there's now way to booting it to the main screen.

Anyone has any suggestion of step by step guide on how to fix it? (I know how to use SPflashTool, enter Recovery mode, etc.)

Hey, everyone!

First time poster, here.

I have been trying to flash a Lenovo Tab 2 A10-70F to stock as I started getting a "System UI has stopped working" error on boot after a factory reset.

Everything goes well with flashing the device until I try to turn it back on and it just won't boot to the OS - I feel the vibration and the screen just keeps turning on and off.

Might I be doing something wrong? Maybe using the wrong stock ROM?

Also, I am avoiding to flash the preloader as I am afraid it might hard brick the device, as I have read multiple times.

Thanks in advance for any help you can provide.

I have already done and gathered everything your trying to do right here >> https://www.androidfilehost.com/?w=files&flid=46340
[Android General] Tzul:
What are you using to compose your messages? A PC? Which browser?

There is neither HTML nor XML input, just plain text, with BBCode markup, which is very common on forums all across the internet.

That's not a list of autospell matches, but a list of username matches! Clicking one simply saves you some typing, but I think it's easier to just type the username and ignore the dropdown list. Especially for a name as short as mine.

If you get a "message too short" error, then your message is probably too short. Your last reply to me landed all inside my quote, for example. That probably doesn't count as a message.

There's a "Reply" button and a "Quick Reply" beneath each post, right? Clicking "Reply" should paste a full quote of the referred message into your text field, which you can then edit - or remove completely. But "Quick Reply" will bring you to a seemingly empty text field, and later prepend a full quote of the message you replied to - I never use this one.

As for your "@" problem: Typing "@Tzul This is a test. Maybe some more text to make the message longer." without the quotes should work perfectly fine...

The scatter file is included in every SPFT firmware archive, or in my TWRP download. Note that while there are two scatter files, labelled "Android4" and "Android5", they are virtually identical, the only difference is the project name and preloader filename - absolutely uncritical information.

You told me you tried to read my post in the German forum with Google Translate, and the scatter file is attached to that for download as well...

Also, I've already referred you to this post, from which you should have taken at least two things:

1. MtkDroidTools does not work with this tablet, ignore it.

2. Get the latest SPFT (from here, link from this topic's first post)

To quote myself:

By the way, the latest version of the SPFT, v5.1548, makes readback (backups) even easier: open its "option.ini" file, find the "[ReadBack]" section and change the line "ShowByScatter=false" to "ShowByScatter=true". That way, the Readback page will automatically list all the partitions from the scatter file loaded on the Download page. You'll still have to double-click each entry to change the filename, though.

How's that for semi-automation?

[MENTION=2895182]clsA[/MENTION] You've gathered his proinfo and nvram? ;)

He could just install TWRP and make backups with that, but I think it's good that he's trying to learn how to work the SPFT, too.
[Android General] charlestek:
Yes, I could certainly install TWRP and was going to do that, but I would first have to upgrade to the last Kitkat build with the last incremental or the last Lollipop build with the last incremental first, as well as then probably installing the root sofware etc.

The point of the exercise was to have a baseline backup without anything else in it. I suppose since there is already access to the intial base KitKat rom , that therefore I am duplicating effort, but I keep on remembering people who have tried to downgrade from Lollipop using the initial KitKat rom having some assorted problems with the wireless id and something else. Now I have not gone back and read those posts, so they could be not really true or something else unrelated.

BTW, I just accidently moved a closing BBS tag [/foo] accidentally to another place in the text, when I tried to post I got the same error message, "my message is too short'

It appears that the person who wrote this BBS was lazy in handling errors/exceptions, he seems to use that error message for any error.
[Android General] Tzul:
[MENTION=7184758]charlestek[/MENTION] You did it again. You placed the bulk of your reply inside my post you quoted! :)

Like I said before, this does not count as a message. You're trying to make a post consisting of nothing but quoted text, which the board software assumes was not typed by you, hence you get the "message too short error".

A quote looks like this (without the space after the opening square bracket):

[ QUOTE=charlestek;65233949]... some text here
... more text[/QUOTE]

The first parameter after the "=" is obviously the name of the user that gets quoted, the second is the ID of the quoted post. But you can omit those and write:

[ QUOTE]... some text here
... more text[/QUOTE]

You can also use the buttons in the toolbar above the text entry field (advanced view has more) to generate BBCode tags like this (they don't need to be all uppercase either).

So, just remove the quoted text, or break it up into several blocks (by inserting [ /QUOTE] and [ QUOTE] where necessary), beneath which you can write your actual message. Don't write it between [ QUOTE] and [ /QUOTE]!

The scatter file inside the official OTA updates simply lists the partitions and their start addresses. This is not sufficient for the SPFT, it uses another scatter file format with more info.

That is another misunderstanding. The SPFT reads raw data, and it writes raw data. You don't need to make data "flashable".

If you use readback to save partitions to separate files, you can simply flash those files via "download", without having to change anything.

But you can also use readback to save multiple, or all, partitions to a single file. In that case, you need to split this into separate files before flashing, one per partition. That's what the article you found uses MtkDroidTools for, apparently. I didn't know MtkDroidTools had this feature, although I pretty much used to do the same. I made a single readback region, start address 0x0, size 0x3A2D80000, and thus saved all partitions from pgpt to userdata to a single file, which I then split into multiple files with a simple program I wrote.

With the new "ShowByScatter" feature, this isn't really necessary anymore.

The scatter files for the SPFT include a filename for each partition (well, for partitions marked as "download"). When you load a scatter file on the Download page, the SPFT searches for these filenames in the scatter file's folder, and if present loads them for downloading/flashing. If the files aren't present, or if you'd like to flash different files, you can simply click on a field of the "location" column to select another file to be flashed to the respective partition.

For the Readback page on the other hand, the filenames from the scatter file are ignored right now, and default to "ROM_0", "ROM_1", etc. You can double-click the location column to set the output filename (and the address and size values, but you don't need to change them when you use the new "ShowByScatter" feature).

I hope this clears things up now.
