Hey Guys need your help.

I had bricked my phone on Sunday. Today i have managed to get it working somehow but there is a catch here.

I had taken qcn backup long long ago on my phone.

1. If i restore my original qcn file then my mobile restores its imei no for both the sim but then my radio setting is getting locked to off position. See screenshots.

2. If i do not restore my qcn then i do not have my imei no but my radio setting can be changed to on or off. But it makes no sense as my imei no is not available, my sim card do not work.

How to restore my imei no and other information from qcn file without losing radio on/off feature.
[Lenovo Vibe P1 Guides, News, & Discussion] Smarty_009:
Hey guys a new query here. Your expert opinion is required.

Check this attached screenshot.

I have range of both the networks. IMEI is also my original IMEI. But baseband is unknown. I remember baseband had some value. Why is it unknown now. Any idea?

Is there anything abnormal to worry or shall I ignore it?
[Lenovo Vibe P1 Guides, News, & Discussion] Smarty_009:
Hey Guys

Today i have intentionally hard bricked my own Lenovo Vibe P1 (P1a42) just to demonstrate you all how to recover the dead (hard bricked) qualcomm devices.

This process is more or less same for all the qualcomm devices. In some devices other steps may be needed where you will have to wipe entire ROM space and make a single partition of ExFAT format.

Well i have tried to make the video in such a way that i include more or less everything possible. Please bare with me.

Could anybody give me an pertinent answer? Before i flash my phone rom from Android 6.0.1 VIBEUI 3.1 (not ROW) to Android 5.1 (ROW) with QFIL, the phone BOOTLOADER should be LOCKED or UNLOCKED? My phone status now is LOCKED.

I don't want to get that SAHARA fail error and brick my phone.

Thank you !
[Lenovo Vibe P1 Guides, News, & Discussion] Starchm:
Will be locked, but on lollipop row the c72's nfc chip not work if i know right
[Lenovo Vibe P1 Guides, News, & Discussion] leviathanus:
Not a big problem. But i just flash to Android 5.1 and i lost both my IMEI and serial number and i cannot conect to any gsm network. What should i do?
[Lenovo Vibe P1 Guides, News, & Discussion] Smarty_009:
Already replied you on youtube. It doesn't matter what is present bootloader status when you flash new rom using QFIL.

Secondly you will have to restore your imei no using your own qcn backup or by rooting the rom and then using app to manually entering the imei nos. It is not good to use fake or someone else's imei no. So please restore your own only.
[Lenovo Vibe P1 Guides, News, & Discussion] leviathanus:
Thank you very much for your answers. I will root the phone using KINGROOT (i think it's ok) and use an app to manually enter imei. I have both on my phone package, no problem.

By the way, what is QCN backup? I'm sorry , i don't know.

Thank you, again.
[Lenovo Vibe P1 Guides, News, & Discussion] Smarty_009:
There is already twrp backup of rooted rom available or else you can root using supersu. Complete guide is available here in forum or on my YouTube channel. Lenovo Vibe P1 everything: http://www.youtube.com/playlist?list=PLMDkgo5euoOCArzKc1yl7WuS1szO8inlC

[youtube]kFWmrzcl6pA[/youtube]

[youtube]e6eprbeUfIs[/youtube]

As far as restoration of qcn is concerned it is something like library where your rf nv data is stored like which band to use and which not to use. Your imei no and many other settings.

It is recommended that everyone makes qcn backup after rooting as it helps in restoring phone in short time after brick. Checkout my Unbrick video on my channel where I was able to Unbrick my phone after it was totally bricked.

[Lenovo Vibe P1 Guides, News, & Discussion] leviathanus:
Unfortunately Kingroot failed to root my phone. To run "Advanced flash unlocked bootloader & recovery" using Qfill, can i add those files necesary into the "emmc_appsboot" folder from firmware_P1a42_S135_1510131022_Q20248.2_ROW_ that i allready flashed or i must make another flash with P1a42_S272_160506_ROW_QPST posted here on this thread and add files from that folder? I am not sure what version af Android is that rom S272.

I want to emphasize that i allready made two upgrades on this new Android 5.1 and now I'm at P1a42 S140.
[Lenovo Vibe P1 Guides, News, & Discussion] Smarty_009:
Latest rom is s288. This is marshmallow and both twrp and superSu are working with this rom. With older version of the rom like s135 and s140 bootloader was not unlocked. I recommend the latest firmware configuration only. As without unlocked bootloader twrp cannot be installed. As far as rooting is concerned s140 or s142 was rooted if am not wrong. It's been so long so am not sure exactly but I remember we used to root using king root then use supersumepro to replace king root and install supersu.

It is strictly recommended that you flash files of one rom package as a whole. Some files from one rom and some from others may have catastrophic effect. Only do it when you are sure like stock recovery of some of the rom version were different so you cannot interchange. However in some cases it was interchangeable. Programmers are interchangeable. Avoid swapping. Better to download full rom packages and flash Complete package as explained in guide. Nobody may be able to help in case you hard bricked your device.
[Lenovo Vibe P1 Guides, News, & Discussion] Smarty_009:
Bro you asked about s272 rom version

Here is everything you need from every rom link to drivers etc all resources

http://4pda.ru/forum/index.php?showtopic=703249&st=2840
[Lenovo Vibe P1 Guides, News, & Discussion] leviathanus:
So, now i should flash again and get Android 6 ROW version and again use Qfil to run bootloader unlock and recovery, root my phone , install SuperSU and the use an app to enter Imei. Right?
[Lenovo Vibe P1 Guides, News, & Discussion] Smarty_009:
Yes in case you are looking for this rom. If you go through older post or xda you will find qcn backup of P1 which you can restore and then you can just change imei no. Using qpst or any other app.
[Lenovo Vibe P1 Guides, News, & Discussion] leviathanus:
Ok. Thanks a lot and sorry again for so many questions.

I have a lot to learn about Android insides.

What aplication should I use?

how to flash twrp on lollipop ?
[Lenovo Vibe P1 Guides, News, & Discussion] Smarty_009:
I guess bootloader is locked on lolipop.
[Lenovo Vibe P1 Guides, News, & Discussion] tombassi:
wow so I have to flash back to 6, I unlocked the bootloader in 6 you mean it locked after downgrade?
[Lenovo Vibe P1 Guides, News, & Discussion] Smarty_009:
Well as far as I know while flashing the rom you did flash Emmc_aboot so it's locked now. Check if it's unlocked using adb /fastboot and let me also know.

My phone has become very sluggish. Can't even answer calls properly after installing xposed. I have disabled any Module that might cause that. Anyone else facing the same ?
[Lenovo Vibe P1 Guides, News, & Discussion] Slamka:
After instaling Xposed my rooted phone started to be very "funny" as well.

After one day of normal usage it gets freezed, so I restared device. It did not booted correctly, it stops to boot at Lenovo sign. Restarted again, a funny information about "application getting updated to newest Android" appears (Like when you install OTA update). Funny is, that it counts 211 apps, but I had only around 130 apps installed.

After this experience I rather removed Xposed, I never used it before so I think I will not miss it.
[Lenovo Vibe P1 Guides, News, & Discussion] coolsid8:
How did you uninstall it ?

Also, just a doubt, why the performance of this phone so bad as compared to Moto X Play ( Same specs ) ??

How did you uninstall it ? We need to flash the uninstallation zip in the recovery, right ?

Also, just a doubt, why the performance of this phone so bad as compared to Moto X Play ( Same specs ) ??
[Lenovo Vibe P1 Guides, News, & Discussion] Slamka:
Just through settings, applications, clear all memories and data and uninstall..
[Lenovo Vibe P1 Guides, News, & Discussion] pabgar:
I used Xposed on Samsung Note 3. Xposed is a bit whimsical app ( or rather app environment ). At this moment as I understand it is in alfa stage. I strongly recommend, that those who wish stable phone, do not install Xposed at the moment.
[Lenovo Vibe P1 Guides, News, & Discussion] coolsid8:
Xposed is excellent and stable but with OEM layers and customizations, it becomes a mess. I used it in my Nexus 5 and it was fantastic on it. I think that's why it sucks on this phone.
[Lenovo Vibe P1 Guides, News, & Discussion] pabgar:
Fully agree. Xposed is not for every phone. And not for everyone.

as you can see , no bootloader status , do you think I must go back to 6 as it was very easy to unlock and flash twrp in 6 but I wanted to use stock 5.1.1 that is why I downgraded

Hello,

I have a vibe p1 c58 2GB RAM / 16 GB sd card version. How can I install original stock ROM downloaded from vibeui.com?

I want to install VIBEUI_V2.9_1608_5.146.1_ST_P1c58 ROM downloaded from http://www.vibeui.com/vibeui/rom3?key=P1c58

I have a vibe p1 c58 2GB RAM / 16 GB sd card version. I installed P1a42_S288_160721_ROW_RAW_QFIL ROM a few months ago. And I had to change IMEI number of vibe p1 because of my country's tax regulations. It looked like everything goes well. But when I travel to another country, I have problems with cell reception. Phone cannot register itself to cell network. I cannot even dial emergency number. What could be wrong, how can I fix this? I installed a42 ROM to c58. Is it possible this cause the problem. I'm thinking to install stock ROM of c58. Do you think this could solve the problem?

Hi dear

This is regarding p1a42_S288_160721_ROW for TWRP a post created by pabgar to upgrade to 160721 for those who have TWRP already installed

I have a problem

The unpacked vol is about 5.5 GB and I put it in the folder to my SD card where TWRP images are held

I restored and following error as in attached snapshot occurred (In red color text) and the restored vol was about 3.5 gb means all 3 images as reported in error could not be restored

Please help

This is how i root my P1a42 after so many failed due to too many error encounters including "too many links", If you follow these step correctly you will succeed rooting your phone

1. Download P1a42_S288_160721_ROW_RAW_QFIL (Find from google or within xda work a bit to success)

2. Flash this Row using QFIL with normal setting (do backup because this will for sure delete all your files)

This time flash with "rawprogram0"

3. reboot your phone and skip everything and turn it back off to flash using QFIL again but this time under the XML setting choose "rawprogram0_aboot+twpr" hold your VOL+ button to prevent the mobile from blocking you editing the system files

4A. Try boot to recovery now to see if you succeed if you are still in the normal recovery follow step below, if you succeed then follow step 5

4B. Now download the tools below:-

a. ADB tools (as usual you can find it from google try these keyword "how to flash using ADB")

b. TWRP recovery img i use twrp_passion_row_recovery_.img (as usual google it)

c. copy the twrp img into the adb tools folder and click CTRL+SHIFT+RIGHT CLICK in that folder and choose "Open Command WIndow Here"

d. MAKE SURE YOUR DEBUGGING MODE IS ON AND YOUR USB IS CONNECTED TO YOUR PHONE AND PLEASE ALLOW DEBUGGING MODE FROM YOUR PHONE AND REMEMBER YOUR PC/LAPTOP

e. type commands below

adb devices

adb reboot-bootloader

fastboot devices

fastboot oem device-info

At this point you should make sure that your adb window is telling you as below

(bootloader) Device tampered: true

(bootloader) Device unlocked: true

If not your device is locked then type

fastboot oem unlock

if you are unable to unlock it please google how to unlock them first

after you have successfully unlocked your oem type the command below

fastboot boot twrp_passion_row.img

5. now you should wait a few second till you phone boot into TWRP then you can install SUPERSU (download the zip from xda and copy it into your internal storage)

after done, reboot and then go back to ADB and type command below

adb devices

adb reboot-bootloader

fastboot devices

fastboot flash recovery twrp_passion_row.img

and now yor recovery is permanently become TWRP, please do as the step above because if you do the other way around, it will not work, you must boot to twrp and install SuperSU first before flashing permanent TWRP recovery (Only for those who are unable to flash TWRP using QFIL)

i hope this help, i spent a month back and forth like an idiot with no success, just hoping nobody else do the same mistake as me

BTW, i have not yet able to get xmodgames to work on p1a42, i tried CM13, SuperSU, so far no luck , i have flashed lolipop to marshmellow if anybody succeeded getting xmodgames to work on this device please do reply me here!! have fun peeps

Thank you for your reply. I would like to explain whole story:

2. It worked in my country.

3. When I traveled to 2 different countries, I can't use phone with GSM networks.

4. Now I re-flashed with S135 with qfil. But I haven't tested it yet abroad.

5. I also found another rom: 1627 ST from 4pda.ru: VIBEUI_V3.1_1627_5.195.1_ST_P1c58

First I will try S135 at abroad. If it will not work, I'll let you know. I may try 1627 ST also.
