stock rom for lenovo a3500 f.
[Lenovo A3500 Questions & Answers] leripe:
Sure can! :)
[Lenovo A3500 Questions & Answers] alvarez3010:
find the right thread

hi, because i was in doubt on witch model is my lenovo i went to our russian friends forum and i got 3 stock rom packages A3500 F, A3500 and A3500 FL. because this is a budget tablet i am trying to learn more about what is a ROM and how i download it as a image file and i see on you tube everybody flashing .zip files with TWRP recovery . my tablet gets frozen on logo (no OS) but i still can boot on recovery, this is not the right thread but it would be great if you could point me to the right place so that i can start to learn from the right place.

Thank you.
[Lenovo A3500 Questions & Answers] brickowner:
Anyone know how I can unbrick the model with number 59410286 with a "MTK 8121 QC" CPU? It's labeled "A7-40 A3500-FL", so I followed the guide here, not noticing the CPU is different, and by that I bricked it.
[Lenovo A3500 Questions & Answers] leripe:
Depends how bricked it is? Can you access recovery? Do you have backup? What exactly is not working and what you did to brick it? The russian lenovo forums might have right rom and stuff for your model.
[Lenovo A3500 Questions & Answers] leripe:
From recovery you need to flash recovery flashable zips. Image/bin flashs are generally via pc/Windows with some program/tool like in this guide.
[Lenovo A3500 Questions & Answers] brickowner:
I used one of the russian roms and now it's working again. :) Thanks for helping.

It was again for the wrong CPU, and flash tool showed an error message. Maybe it was just stuck somewhere.
[Lenovo A3500 Questions & Answers] alvarez3010:
i have the exact same device as you , it's bricked but i have access to TWRP to bring it back to life , can you describe how did you did it in a kind of step by step . it would be awsome or even if you can make a rom backup from your now NOTbrickedowner lenovo and .zip to me ? I'm happy for you :D .

Sweet taste of achievment

(*) I AM A JUNIOR MEMBER can't post links, so private message me for access to required:

SP Flash tool app, latest release

original SCATTER file ROM and auto-install USB drivers.

Before do this, check your model - A7-40 ( A3500-FL ), A7-50 ( A3500-F, A3500-H, A3500-HV ) in my case A7-50, A3500-F

If you reflash the tablet with incorrect ROM you can damage it. but if you are here you have past that concern, right ?

1. Download the ROM A3500-F_A442_01_34_140904_ROW This is a .RAR containing all that is mentioned in these instructions (*)

2. (**) my device turns ON and freezes or i boot in TWRP. can't switch off when needed and the battery is not removable. it was my biggest challenge as using the flash tool you need to turn off and on a few times, so FIND THE RESET HOLE that you can RESET using a paper-clip (in my case isvery close to the SD card is inserted.

3. Install drivers - i have a .bat that makes the job very easy

4. Start Device manager to control the driver installation.

------

5. Start SP_Flash_Tool.exe

6. Press "Scatter_loading" and load "MT6582_Android_scatter.txt (*)

7. Press "Download", SP_Flash_Tool will load necessery files.

8. Switch off the tablet. (**)

9. Press and hold the Volume Down button until you connect the micro USB cable.

10. Windows will start installing Preloader USB VCOM (Port X).

11. don't worry if the tablet starts or shoes charging symbol .

12. When Windows finished with the installation, reconnect the tablet again while press and hold the Volume down button (the tablet must be switched off). (**)All this things do take time be patient, use good quality usb cables and NEVER break the connection .

All i gave you is words , check some videos about the SP Flash tool...

All i can say is that after 3 months of mute , when i turned my tablet on and i heard the lenovo booting sound it was AMAZING but, it took 11 minutes in is first boot. all the times that i was tempted to grab 80 quid and buy a new one, i'm just so glad i didn't.

Like i said i have loads of info on most lenovo mobile devices, but (*)..... so, contact me if you need !

thank you all, but now i'm going to leave this old reliable Ubuntu dual boot win7 for a few days and explore the new toy toshiba satellite L50 and the pre installed Win 10.

Peace !

Hello, I rooted successfully my tablet and thank you for the tutorial.

Is there any custom rom for this tablet? The Cyanogenmod doesn't have anything about. :confused:
[Lenovo A3500 Questions & Answers] _purple_:
After following this guide, is it possible to flash TWRP recovery from within CWM recovery?

The only custom rom I was able to find is a clean KitKat port (probably AOSP) here: http://www.needrom.com/download/a70-40-a3500fl/

My son's tablet became unstable and after several attempts of fixing it, I decided to install ROM from scratch so I followed this guide and links and did it with original ROM and updates OTA., or more like Lenovo smart asistant.

Everything works fine now and thank you! for that!

There is good info here too (and surroundings... :) )

[Lenovo A3500 Questions & Answers] mirrou:
Yesterday I tried to root my a3500 fl, with the old flashtool wersion it install recovery but did not root. Next I tried with newer flashtool, but during the process there was lost usb connection. Now I can not start the tablet.

When try again to root it it was detected on cmd (on linux):

path name dev/ttyACM0, same for the port name

but process never ends and nothing happen. The tablet still not response.

Can someone help, please!
[Lenovo A3500 Questions & Answers] dzincha:
Mirrou,

Can you get in recovery?

If not try to flash recovery. I prefer CWM on A3500FL.

Then download Custom ROM ( I prefer RR 5.7.4) and install. During installation it give message - detected file system ext4 bla bla - but leave it for ~ 5-10 min and it will finish with message script finished succesfully - 1.

After that gaps should be flashed if you want to have Play store. http://opengapps.org/ there select arm, android 6.0 and type. I prefer pico.

So prepare sd card with those 2 files on it - rom and gaps and enjoy.

Hi,

My TAB Lenovo A7-40 Wi-Fi Mediatek MT8121 is bricked on a bootloop (lenovo logo)

I can access anyway to the recovery TWRP 2.8.4

Hardware : MT8121

Model : Lenovo A3500-FL

Build number :

Build date UTC : 19700101-000000

Android v :

Baseband v: -----

Kernel v : 3.4.67 (jenkins@diyisoft83) (gcc version 4.7 (GCC) ) #1 SMP Thu Nov 27 22:45:33 CST 2014

I tried to flash (with sp flash tool) a lot of stock roms but with hardware MT6582 , mine is MT8121

and downloaded them successfully, confirmation by the green circle on SPFT (drivers USB/ADB/MTK are installed and detected by W10) but unfortunately

when i boot my Lenovo TAB, it is still stuck on bootloop (logo lenovo) I tried with different cable, sp flash tool version, no success.

Could you post please the right stock rom with BB Chip: MT8121, i can't find a link with Google

I read that user brickowner on #144 have installed a working rom MTK 8121 QC" CPU, but don't know which one :(

Thanks in advance for your help ;)
[Lenovo A3500 Questions & Answers] _purple_:
Before I touch anything on my device, I'd like to ask, how can I check what baseband chip it has? My device has MT8121 soc but I do not see anywhere in this thread the soc being mentioned, just the baseband. Why?
[Nexus 5 Q&A, Help & Troubleshooting] kaspar737:
So my Nexus 5 sometimes won't charge. For example, I plug it in at 5%, and after an hour, it is still at 5% or lower ,often even at 0%, so when I unplug it, it instantly turns off. Sometimes it charges fine to something like 20%, then it stops and battery slowly starts to discharge. There are days when it's perfect, absolutely no trouble. I should also mention that when it charges normally, the charger plug is warm-hot, when it doesn't charge, it's cold.
[Nexus 5 Q&A, Help & Troubleshooting] :
It's hardware. Either the cable, the charger, or the phones mini USB port.

Try a different charger and cable for starters.
[Nexus 5 Q&A, Help & Troubleshooting] rafmjz:
Its the hardware, maybe the battery or something and its also happening to LG G2 (N5 brother), so LG's faults.

But Google posted oficcially some ways to fix it, you only need to power off the phone and plug it. Wait 30 minutes and then turn it on again, leave it charging and this time probably works.

It doesn't happen to often, but when it does, its really annoying.
[Nexus 5 Q&A, Help & Troubleshooting] badboy47:
I remember having this issue but only with wireless charging. Seems like an issue with the wire.
[Nexus 5 Q&A, Help & Troubleshooting] hotweiss:
I had this issue with my Galaxy Note. It was actually a faulty chip on the motherboard that was causing my charging problems... None the less, I would first check your cable and then the micro USB port.
[Nexus 5 Q&A, Help & Troubleshooting] kaspar737:
I have 3 chargers and 2 USB cables, tried all the possible combinations, nothing. What should I look for about the USB port?
[Nexus 5 Q&A, Help & Troubleshooting] :
My 5 year old daughters Galaxy tab 3 is the same. I can tell the plastic part of the mini USB port is snapped. So only the wires are holding it together. It will charge... But only when it's laying on a stable surface, untouched and sometimes I have to wiggle it til it's charging, then leave it alone til it's done.
[Nexus 5 Q&A, Help & Troubleshooting] kaspar737:
Does it say it's charging? For me, even if it isn't charging but is plugged in, it says "Charging (AC)".
[Nexus 5 Q&A, Help & Troubleshooting] :
Yeah, our tab makes the plug in noise over and over til it's good.

But just cause it says it's charging doesn't mean every pin is making proper contact with the charger or device.
[Nexus 5 Q&A, Help & Troubleshooting] kaspar737:
I cleaned the phone's USB port with a toothpick and compressed air and so far, it's working all right again.
[Nexus 5 Q&A, Help & Troubleshooting] kaspar737:
Oh well, it's doing that again. Charged 80% in 7 hours. Cleaning USB port didn't help.
[Nexus 5 Q&A, Help & Troubleshooting] chaco81:
my N5 does this but with wireless charging..

sometimes i put it on when i go to bed, and i know it starts charging

in the AM i see its lower ... checking the batt stats it shows that it charged for a few mins then stopped

dunno yet whats up, it happens sporadically.
[Nexus 5 Q&A, Help & Troubleshooting] kaspar737:
Any chance software could cause this? Rolling back to 4.4/4.4.x or resetting factory settings would help?
[Nexus 5 Q&A, Help & Troubleshooting] chaco81:
that could be next step.

if a factory reset doesnt help, then u have a hardware problem. Does the batt info says "healthy" or "good" for the battery?

have u tried using a toothpick to ensure all usb pins are clean of dust?

maybe u can get another battery and change it... if a cell is going bad inside the batt it can do that too
[Nexus 5 Q&A, Help & Troubleshooting] bblzd:
Good thinking. Glad to hear it's working better now. :good:
[Nexus 5 Q&A, Help & Troubleshooting] kaspar737:
Where can I see battery info?

I have 1.5yrs of warranty left, there's no point for me to try and change the battery on my own.
[Nexus 5 Q&A, Help & Troubleshooting] kaspar737:
Today it didn't charge, so I decided to restart. When I had just powered off, a fully charged battery icon came on the screen and stayed for about 15 seconds. Then the screen flashes black and started showing the charging battery icon.

Anyways, I am going to flash the phone back to stock when I have time, if that doesn't help then it's going back for repairs.
[Nexus 5 Q&A, Help & Troubleshooting] chaco81:
download CPU-Z as the simplest way to tell

go to the Battery tab and it will tell ya the "Health" of the battery. Mine says "Good"
[Nexus 5 Q&A, Help & Troubleshooting] MrObvious:
Another trick is to buy a wireless charger. If this ever happens to me I'm doing that.
[Nexus 5 Q&A, Help & Troubleshooting] cvin88:
This has happened to me months ago and I tried everything. Turned off my phone to charge, tried different cables...nothing worked.

Then I started charging my phone with a blackberry charger and it has been successfully charging my phone ever since. And it charges faster than the original charger. When you plug the charger into the phone, it's very solid, whereas the original charger is somewhat flimsy. Not sure if that may be the case. But that's what I did!

Hope this helped!

Amazing Development

Hi [MENTION=1755963]anirudhks[/MENTION]

This and your other ROMS is the maximum and most quick development for a LG G Pro 2. Thanks a lot....You'll soon have your beer...:fingers-crossed:...

However, I haven't installed this ROM yet.....But is that anyway that i can install LG Quick Remote App. (Since i love that and use it regularly and the only LG app that i use.)

I want to give the AOSP a try and i;m sure it'll not disappoint, but just confirming a few things before i do.

Thanks a lot. !!!

All the best

Buddy, this rom is still stock based, so LG apps should still work. Its is AOSP Flavoured, Not a AOSP rom. But I guess that may come in the near future eh? Anirudhks? ;)

Problem with my D838 in Egypt

I bought the D838 from Emirates 2 weeks aga , and use it in Cairo/Egypt. I have the following 2 issues:

1- Not bale to make Video call , and always receive the message :" When in Roaming, no video call is possible" . I have checked with Vodafone support in Cairo and made sure that Global roaming is off, but still get the same message.

2- can not receive or send MMS. it always fails.

3- There is a software update on the phone, and every time I try to update, I get error after few seconds.

To me it seems that the ROM is only for Korea, so the phone , when using Vodafone Egypt, thinks he thinks am using a Korean SIM in Cairo, so there is roaming. I can not find any other reason. Except those 3 issues, I am using the phone for calls, sms, emails, Facebook, whatsapp,...

Can some one advise ? is there a ROM that I can download safely to overcome this ?

LG support in Cairo, said they only support LG G Pro and nit Pro 2.

Thank you all in advance
[LG G Pro 2] anirudhks:
The ROM is not Korean . its singapore base .. There should be no problem in terms of roaming . however I am not sure about your video calls. MMS should work and you need to add the APN manually
[LG G Pro 2] mseif:
Thank u anirudhks, For the MMS, Vodafone in Cairo has checked and verified the APN for both SMS ( which is working) and for the MMS which is still not working.

here are the SW info in my mobile :

OS 4.4.2 , baseband M8974A-AAAANZM-1.0.190084

Kernal ver 3.4.0

Build # KOT49I-F350L10d

Software ver F350L 10d

you are saying there should be no problem in terms of roaming ? How is that , while every time i push the video call button, I get the message that " since there is global roaming, no video call ". I made sure that Global roaming is OFF.

Could it be because the Seoul area code is 02 exactly like Cairo area code ? Any way I tried " Disabled" and even made a Cairo tag for 02 , but did not work.

Also not able to update. I hear that there is ROM for Arab countries ( Samsung do that ) , can I update the ROM?

thanks again
[LG G Pro 2] anirudhks:
In this case I would suggest you to use my other Dustre ROM , as thats pure Singapore based ROM , apologies if i overlooked this one .. but that I am sure .. try that and lemme know..dont install the lollipop but the Kitkat version
[LG G Pro 2] mseif:
Thank u again anirudhks.

1- How can I get this ROM ? would it fit the Arabic area am in ?

2- How to install after download ? is there a manual or steps somewhere?

3- Any chance that it would ruin my device ? Can I rill back ?

many more thanks.

ONE IMPORTANT NOTE : I found out that the software version is F350L 10d and NOT D838 !!!!!

[LG G Pro 2] darkangel1016:
Hi, I am not sure about this phone as i have not yet rooted my phone. do this and check :

before flashing ROM:

Install ES Explorer or use your favorite root browser

Enable root access (in ES Explorer > Menu > Root Explorer > Mount R/W > Select RW for '/' and '/system)

Copy modem.img to your SD.

Flash the ROM

Navigate to /system/etc/firmware

Rename the flashed modem.img to modem.bak

Navigate to the oiginal modem.img in the SD card and copy

Navigate to /system/etc/firmware and paste

Make sure permissions show '-rw- r-- r--' (Directory list) or 'rw- r-- r--' (file properties)

Reboot

the above usually works for network issues. This is true for all network issues

---------- Post added at 10:02 AM ---------- Previous post was at 09:56 AM ----------

Hi , i was a lurker as i had a new phone and was not so eager to root as i am using to access office mail.

anyway, if the issue is only about network between D838 and F350, i think it can be easily solved.

before flashing ROM:

Install ES Explorer or use your favorite root browser

Enable root access (in ES Explorer > Menu > Root Explorer > Mount R/W > Select RW for '/' and '/system)

Copy modem.img to your SD.

Flash the ROM

Navigate to /system/etc/firmware

Rename the flashed modem.img to modem.bak

Navigate to the oiginal modem.img in the SD card and copy

Navigate to /system/etc/firmware and paste

Make sure permissions show '-rw- r-- r--' (Directory list) or 'rw- r-- r--' (file properties)

Reboot

the above usually works for network issues. This is true for all network related issues. modem.img is where all radio related information is kept. replacing this solves the problem.

I was using micromax a110 and this solution of mine ensured people using a110 clone were able to use ROMs made by developers in India and vice versa

can anyone check please ?

Hi folk :)

Since few time I got a BenQ F5 nice phone really :)

Root is ok ( I used galaxy verizon way ) but ...

But since I like to make crazy thing on my phone, I wanted to make a backup before to brick it lol

But I don't know How to do q.q

I also think build a cwm for that phone can be really nice but I need to dump kernel and maybe more.

Can someone help me ? ( I'm familiar with adb and a little with fastboot )

Thank you :D

PS : It looks like to be the same hardware than moto G 4G maybe cwm can work no ?

Hi,

Assuming software made for other devices will work on yours is not a great idea. You could end up bricking your device and find yourself phone shopping. ?

There is no section on XDA for your device, you would need to ask here for help... I looked, but can find nothing on XDA for your device,
