How to update Lenovo Tab2 A7 30H to Lolipop from 4.4.2

I am a newbie yet I have flashed some roms from sdcard before, but I am a total NEWBIE!
For some taxing issues they imported Tab 2 a7 30 to Turkey with a "H" code at the end and they cropped calling feature from it.
However I do not care about "calling" but I want to have android lolipop on my device. On Lenovo support site it says it must have the update after July, I can not give link as forbidden before 10 messages.
yet my device says it is the updated version (has definitely 4.4.2 on it I'm newbie not dumb).
I know that there is this flashing by PC (needs drivers and sp flash tool and rom) and also sdcard method that directly installs rom from sd card (needs different rom I guess and deleting caches needed).
So, how would I upgrade, do I need to make it 30HC kitkat to upgrade, how, will it keep its own IMEI then?

any help?

Hey, I have a question. Are Lenovo Tab 2 A7 30 and A7 30H the same? Cos I'm super confused.

A few problems - IMEI, Rom, Root, recovery

Hi I succesfully flashed my brother in laws Lenovo A369i with the latest firmware Lenovo_A369i_4.2.2_(by_xdafirmware.com).zip found at http://firmwarefile.com/lenovo-a369i
I followed this guide and used the flash tool included in the firmware package above, and the latest usb drivers from below:
http://www.modifyandroid.com/stock-roms/lenovo/how-to-install-stock-rom-in-lenovo-a369i/
https://androidmtk.com/download-lenovo-usb-drivers
According to the phone, this version is A369I_S110_140108 - and when checking for updates it says that this is the latest one - but how can I be sure?
I searched on google and most of the times there are sites that claim to have the latest but they don't write which version it is(very anoying) so I can spend many hours(very slow internet connection) on downloading the one I already have or one older.
The information and guides on here Xda has not been updated for a while.
The Phone works with both phone calls and sms, but the IMEI is not written - so should I do that with SN_Write_Tool_v2.1504.00.zip, MTK Droid Tools or is there an easier way to do it - or should I just forget about it?
UPDATE: I got this sorted out now, by rooting with framaroot and using Chamelephon to first make random IMEI then reboot and change the IMEI to the correct ones.
-----------------------------------------------------------------------------------------------------------
My second problem is that the phone were unlocked before I flashed it and now its locked again - are there a guide to unlock it?
The phone were not bought with subscription, we bought it here in the philippines from Lenovo Mobile( not real Lenovo company but dealer/importer allowed to use the name(for god sake stay away from them)) and after repair the dealer sent back different older model(this A369i) with less battery and locked to Globe. After trying for 2 months to get them to give us the unlock code, I gave up fighting them and had it unlocked at phone repair shop were they had to use a box to do it, so I never got any code.
---------------------------------------
Third problem: I need to root it but not sure which tool to use?
Update: This is sorted out, see above.
--------------------------------------------------------------------------
Fourth problem: I like to install custom recovery on it - but which one work best and allow to flash from SD card?
As this is the first time I have flashed an Mediatek phone, are there anything else that I need to do?
Hope an expert can help me

galaxy j700h/ds mtk6572 black screen after flashing orignal stock rom.

hi all! actually i am having a strange problem with my j700h mtk6572 china device.the problem appeared first when i tried to install custom rom on my china device which failed giving me a broken android device.what next was that i flashed a wrong rom with sp flash tool and then the condition got even worse that from then onward i wasnt able to even boot..so i kept struggling to find the exact rom for my android..
when i was failed completely i decided to go to the mobile phone shopfrom there i bought an exact simmilar china phone and readback its rom with sp flash tool and mtk droid tool and when i flashed this rom the sp flashed tool started to flash it (this indicated it is the compatible rom because sp flash tool didnt found an issue).after when the phone booted up,...
strange boot scenarios after flash
the phone shows nothing on screen,its completely pitch black.
i can hear the boot sounds.
power key and volume keys are responding
while chaarging the flash led glows
some additional info about my device
the back flap removed shows me behind the batter the following specs
model_ sm j700h/ds
fcc id_ a3lsmj700h
ssn_ j700h/dsgsmh
rated 3.8v 2600mA
(there is a sticker of some farooq mobile, may be the distributor or developer.)
internel features
i remember once i opened the about section that showed itself j700f
the internel memory was 16gb
before by first hard reset the seemed to be android lollipop but after first hard reset onward the phone had a kitkat lock screen.
i even checked some recovery files manually that shows some files etc indicating sm-g530f
.
the nutshell problem
keeping all the scenarios in mind a came to the conclusion that nothing is wrong with rom because sp flash allowed it.
the issue is not confined to some screen attachments or driver because it dont even connect to my pc(just gives some two unformated partitions dissapear and reappear when i connect with pc using my cable).
i request you all if there is some official or developer who knows about china devices to please cooporate, as i am dead tired with this condition.and i made xda id just to post this thread...
any help will be highly appreciated.

Hello
On the sticker it shows it as j700h and inside the device it's j700f?
Hard reset doesn't downgrade the frimware
And you said some tools indicate IRS g530f?

@HoPe thanks for replying.
You got a point here,I am starting to ponder over it..actually about smg530f I am not sure,I don't remember exactly.what I am sure of is that I flashed the exact ROM and still its not working, and secondly that the lock screen style turned to KitKat 4.4 style when I did factory reset..I wanna know that, is there any thing apart from ROM files that I need to flash, like display drivers,imei etc..can I do a hardware replacement of emmc.
What partitions loads the hardware components like display.sdcard etc.
Any help is appreciated in advance..

Hello, so far i don't think this device is reversible since it seems to be a rebuilt device -modifed-, the hardwares and imei are changed. this explains why the black screen popped, better buy a new device so far or maybe 
 @Droidriven would you check it out ?

If it says J700H on the sticker(I'm assuming you mean the sticker behind the battery), but says J700F in system settings. That could be for a few reasons but it more than likely started out originally as J700H. Here are the possible reasons the numbers aren't matching:
1) the device is a J700H but has been flashed with J700F firmware.
2) The device was originally a J700H but now has a J700F motherboard for whatever reason.
3) The device could have originally been a J700F but has had the casing replaced with the casing from a J700H.
One way to know for sure is to open the device and inspect the motherboard for the model number that is stamped on it.
Edit: Nevermind, you don't actually have a device that is anything, it's not a J700H or a J700F. You have a cloned(fake) device.
There are no stock firmwares for clones that you can just download and flash. The cloned devices have firmware that has been hacked together from other devices, they don't actually have firmware that is their own.
I wouldn't waste my time on this cheap fake want-to-be Samsung crap. You're going to end up chasing your tail trying to manually put a firmware together for the device. Rest assured, you're gonna have to build it yourself if that's what you need, you probably won't find anything that can be flashed as is without making some modifications.
Next time, don't buy a cloned device, they aren't worth it, I don't care if they only cost $2, it still isn't worth it.
If you want a decent device then go buy one, don't buy a device that is pretending to be a decent device. When you try to be cheap, you get EXACTLY what you pay for. Stop robbing yourself.

@Droidriven @HoPe thank buddies for getting to my thread and properly responding..I am very grateful to y,all.actually that $30 clone is not my interest any more.
the day I hardbroked my mobile and the next day I bought the same from the same mobile shop (that too is China fake and is in working condition.) What seems interesting to me is that my older device is not booting even with a firmware of its own kind which I read back from the new j700h!..I wish I could get hands on that Chinese developer who is both a genious and an idiot....!!

This must be because the IMEI that you have is originally from a i9500 S4 then it was written onto the device you have because it either had no IMEI or it did have an IMEI but was blacklisted or was not a valid IMEI for whatever reason.

It wouldn't surprise me if the two devices you had are completely different at the hardware level, they probably don't have the same components so they can't use the same firmware.

Can I repair my cell phone?

Greetings to the people of the forum I am new so I apologize if I commit any lack
My case is so try to update my Huawei CHC-u03 to lollipop and marshmellow with the method of honor 4c
all good up to lollipop and a minor update, then when installing marshmellow (all this from sd with the method from the settings of the mobile) the phone is in bootlog and only says honor
I have not been able to revive it with any firmware from the 3 button method, I have tested with firmware 4.4, 5.1.1 and nothing the phone is still in bootlog
when forcing install from sd only says software install failed
* my biggest mistake was that I do not realize that the mobile is not root and has the bootloader blocked without possibility of unlocking because it has imei and serial number changed
Then can I fix it? or should I call it dead?
sorry i used google translate

When you say with the Honor method do you mean you flashed another phone's ROM on your device?

You should never at any case use another phone's ROM on your device as it will cause lot of problems including hard bricking

Android devices are not like PCs. You can't just install whatever operating system you want. Android is built for the specific hardware and device model number it is installed on, it is not built to work on other devices. It typically destroys a device when you flash a stock firmware or ROM from a different model number.
Your only hope is to flash your ORIGINAL stock firmware for your specific model number.

[REQUEST] Nokia 7 TA-1041 Official Firmware

My partner from Chinese 7to forum had made TWRP adaption for Nokia 5, 6 and 8. Now it's time to find out how to install custom recovery and root Nokia 7.
To achieve that, I need the official firmware of Nokia 7 TA-1041.
That's it. It will benefit a lot for both XDA and Chinese Android communities.
Current version is 00CN_0_64C I think.
Thanks a lot!
UPDATE: I got the Nokia 7 firmware, filename is C1N-0430-0-00CN-B05.rar. But I won't release it until @blackpanther0582 or @Quixote78 got Nokia 2 and 7 firmware.
UPDATE IN Mar 12th 2018 (UTC+8): I released this firmware. You can find it from https://forum.xda-developers.com/nokia-7/development/nokia-7-stock-firmware-t3762166

Can you help me with this firmware bro

I got this firmware from local Nokia Service center where I sent a bricked Nokia 6 to them.
To protect the employee who gave me the firmware, I won't release it immediately.

That's sweet of you. I've just got my Nokia 7 and I might just brick it while playing with it. So, can I at least stay assured that if something wrong happens, you'll privately provide me with the firmware? ?

Phone won't boot
Some help would be fantastic and greatly appreciated. I received the phone brand new just yesterday and have turned it on to set it up but it will not go past the "Powered by Android" screen. I have tried so many times to enter reset menu to factory restore it but it is not possible. I think my only option left is to somehow flash the phone with the original firmware but as I've never used a newer Nokia before, I am unsure of that too. I contacted Nokia online support who refuse to help me because the phone is exclusive to China and I am based in Australia. I feel like I have been scammed with a brand new phone that I can not use.

asking for rom to unbrick Nokia TA 1041
Hello everyone.
I would like to know if you have the rom and firmware of TA 1041 CCN 4GB ram.
I bought it on AliExpress.
After 2 hours of using it , it stopped booting normally.
The phone stays on the Nokia screen.
I cannot turn it off!
When trying to hook it to the PC , the Android driver is there , but their no device detected!
I wonder if some part of the boot chips are dead?
Can someone help him please?
Best regards

The same problem with "Powered by Android", only I'm from Belarus. Waiting for an answer from support.

Any update on this?
Got this phone recently from china (as it is unavailable yet in my country), its great but has a ton of software issues: setup screen constantly freezing, google play fires errors faster then a tommy gun, widgets and apps crashing, etc...
Really would like to be able to flash a clean rom.
Cheers!

I sent my phone back and going to claim a refund. I really want the phone because it has the specs that I want, the size that I want, the build quality that I want, and the look that I want. But it seems there is a software issue that means it doesn't function correctly out of China.

I have the same problem as you, the phone hangs on download mode after I reboot or power down consecutively 5 to 6 times after flashing the rom.
I cannot force flash the ROM, with OST LA, it hangs on "hwcfg" (C1N-0-0430-hwcfg.img) after 117 seconds of attempting to flash.
Google Play Store has been flashed in the original firmware, it is buggy as it doesnt update any application.
I think google applications are causing the phone to hang out and to bug.
I cannot seem to find a clean rom for this phone!

My biggest problem is updating/installing apps, as you said. I'm getting error 404 and no solutions from webs fix it. A funny related issue is that the phone is not showing up in the web version of Google Play (when you do a remote install). At least I think these issues are related.
Did you experience anything similar?

Yes I have experienced the same thing.
I have asked the reseller on Aliexpress for the original firmware.
I am waiting for his answer ...
What concerns me , I cannot find ANY ROM available for this Nokia 7 and the bootloader is locked and cannot be unlocked on fastboot.
I hope one day a developer on xda could give us a clean ROM+GAPPS, with a TWRP recovery.

Support for the firmware is not responding. The theme on community.phones.nokia.com/support/discussions constantly removes.

Any update?
Mine got stuck in "Powered by Android"
