TPT ICS NANDROID Backup (rooted w/superuser - completely virgin) and other goodies!!

Hey hey XDA! (ignore the account name, I was 13 years old when I first joined XDA in like '08)
My father bought a refurbished TPT from TigerDirect and literally nothing worked. I factory wiped it and tried to update it so I could get the cameras working and other such things - but no luck. I started to crawl my way through the internet but neither Lenovo nor anybody else seemed to have the answers. I thought that since I was failing the SHA1 hash checks that I might as well start replacing the files and see where it gets me. Five hours later:
First try to restore my ICS nandroid backup, but if not, follow the mini-guide below! Also look at the end of the post for all my files!
For those of you that can't update because you're failing assertion checks:
Root your current version with one of the root tools in my package. Go to your advanced properties and see which Lenovo internal version you're running "0089, 0075, 0060, etc". There are three toolkits that I included and they all work; use the one for your version.
Flash the Ventana CWM.
Do a nandroid restore through CWM by going to backup->restore. It's going to wipe and install a clean 0075 Honeycomb build.
Root again, the pre 0089 package should be a relatively easy root to do.
Restore the factory recovery. I have one fresh from my tablet and one that I found floating around on the internet. You could use either (the one floating around worked fine for me, but if you want something 'newer' just use mine).
Connect to a WiFi network and check for updates. This is the part where it might get tricky. Not all of the files in the 0075 build that I attached were original (it wasn't my build, not my fault). If you get an assertion check, look at your error and see which file has failed. I only had to replace three files, gps.conf, Generic.kl, and the busybox binary. This theoretically should be the same for you. Try to update without replacement, and as the updates start to fail replace the files that are causing failure. The ones you need are attached in my bundle, but I have others too - so let me know if you'll need them!
By this step you should be on the ICS update. Root using the debugfs kit (in the ICS folder for rootkits) and then flash Koshu's recovery (which only worked for me on ICS). Do a backup. Live a happy life.
This procedure isn't meant to be very 'easy'; I am just attempting to make your inconsistencies match mine so they can be fixed in the same manner. A quick Google search showed me that a lot of people are missing different files with barely any files available. Everything I have was extracted from official packages from previous versions. I think I managed to 'get lucky'.
You can find everything that you need on my website. I won't ever take this down save for a plane crashing into the datacenter where it's hosted. There are copies of all the files I mentioned in this tutorial and even copies of Lenovo's official updates since their servers go down more than Kim Kardashian.
Go to http//davidstancu.me/TPT
I'm also working on a small Android app to replace these files to the factory files (kind of like the way Windows has sfc /checknow or whatever that command is. I would also like to extend a massive thank you to everybody who made the tools that I used to get this done.
Since my account doesn't have 10 posts yet I can't post a link, so you'll have to manually include the colon. Sorry

What is your tablet version? US? ROW?
I am looking for 16 US version.

i have inadvertantly deleted my original ics files when upgrading to Koshu's JB. I need to restore the stock ics so would like to use your cwm restore files.I've downloaded the files but the md5 check doesn't work.I assume it's only because i need the actual name of the folder these files are saved in the cwm backup folder. can you please either post it or email it?

don't worry. I just created a new blank nandroid.md5 file and it took.Unfortunately, my TPT would not boot up. It just stuck at the Lenovo logo. Any suggestions to get it working?

My guess is that a file was corrupted. Try redownloading?

Thank you so much for the detailed guide and the files! My TPT came with a strangely named bladenct...0037_0001 (US) firmware so I couldn't have updated to ICS otherwise.
In other words, confirmed working for a US 16GB TPT. :good:

Based on that version number I'm curious... is that a TPT from Tigerdirect? Is the model number 1839AJ6 or 1839AD7?

US vs ROW

Damn.I justchecked the build.prop and the ICS nandroid backup is for a US version. I've got a ROW version.
Anyone out there got an ICS nandroid ROW backup I can use? I'd really appreciate the help.

I bought it second-hand (and it seems to have had quite a rough life as is cut out for a ThinkPad), but it's an 1839AD7.

Thanks for the reply. I am trying to help another member get his up to ICS, and he has the same weird software version. Did you restore the nandroid or follow the mini guide?

I used the mini guide. Unlike the original poster, I found nothing broken in the stock software. The rear camera has some serious magenta artifacts on the side but that remained in ICS and CM10 so I'm guessing that's hardware damage. (This tablet seems to have been through a lot. Thus I got it at a reasonable price from ebay.)

Awesome! Thanks again for replying.

[Q] New User! Where should I start?

Hi, i just got my Galaxy S3 (SPH-L710) from Virgin Mobile today. I wanted to know where to start reading in this forum in order to not screw anything up on my phone. I am talking about things i need to be aware of when rooting or flashing roms so i don't brick my phone. Thanks guys!

You should definitely start here: Backup IMEI and also back up your EFS ! Theres plenty of guides around here, so help yourself

you should ALWAYS start from there with any android phone(not that, but something like that). i started from there...now i see posts on forum about guys that have problems with IMEI or phone won't boot cause EFS partition is damage(or something)...
after that just READ CAREFULLY when doing something...read the tutorial until you fully understand it... and have patience...don't hurry things.

EFS / IMEI losts are uncommon on brands other than Samsung. But i agree, BACKUP EVS AND NV.
Second, if you're not on 4.3 official, DO NOT UPDATE TO IT via official methods. You'll get knoxxed.

Q| No wifi after flashing D405h system on D415

Ive flashed a lolipop D405H system partition on a D415, now one of the bugs I have is that the wifi cant be turned ON and I get "Connection not allowed" error when tring.
What I tried:
replacing /etc/wifi folder to orginal
replacing /bin/wifi_suplicant to orginal
is there a build.prop tweak ? or any other solution ?

You can install the D415 kernel and it will help a little bit. I used the D405n with D415 kernel to modify the. 405n system. However i couldn't connect to the internet. I'd recommend jist using the whole D41520c system. I uploaded some modded version. It's on XDA..

Since the bands are different you'd probably not be able to. I only did it myself to create a modified system for other international users . it never worked for me either.

For the sake of time saving (since this question has been answered dozens of times already.) It's the base firmware including the modem and various files pertaining to a specific device and system.
Whether you will have luck flashing your specific device bootstack or the bootstack for the system from a totally different device since you're trying to flash an incompatible system on your device I couldn't say whether you'll have any luck with any. I feel as of you're wasting your time with this, unless you do not care about ruining your device. But it may work.
May I ask why you're trying of flash an incompatible system on a different device variant? Seems like you've got some sort of plan, or are you just experimenting. Most people will tell you not to flash systems from different device variants because of the headaches it will cause you. Unless you know exactly what you're doing.
All in all, be careful not to brick your device. Because it sounds like that's what you're trying to do.
Can you give me insight and explanation as to what you're doing?
This is all things you should research before installing things on the wrong device variants.
Please be care full and don't follow through with something you don't fully understand unless you've got a full proof plan to fix anything that will go wrong.
Seriously, Godspeed my friend!

First of all thank you for your response.
Now what Im tring to do is to add languages, I dont want to go through all the apks so I hoped I could make a shortcut, I know what Im doing but this time Im stuck with this bug.
Im not worried about bricking the phone because I can use Jtag and direct EMMC write so its ok even if I destory every thing.
Now about the bootstack Im not familiar with the terminology thats it.
Can you point me in any direction ?

Bootstack directly affects the data connection. And that includes wifi.
However....
I think your biggest issue is the wrong system on your device. You have completely different country device with an absolutely incompatible system.
Good luck with whatever happens for you.

PSA - Never flash another device's persist, IMEI loss understood

Hi all, I've seen that there are a few threads in this and other forums that are saying that using a particular other persist will help restore IMEI, Volte, or other lost functionality after installing a custom Rom and reverting back to stock nougat. As this sort of suggestion has resulted in many devices being permanently broken, I'm sharing a thread I made in potter.
Fix Persist, resolve IMEI=0, Explanation, Requirements
Now, the most important thing here is to NEVER EVER flash another device's persist. Your persist contains key files that have your IMEI data (in encrypted form), and it will not work with another device (or vice versa). In the thread above, I explain what has been happening, how to detect it, what can be done to fix (note - this may differ from device to device - I recommend not applying the fix until after other who have 'fully working devices' can confirm key details, such as the "rfs" user), and why other persist files gave the appearance of working (but were actually causing permanent damage).
Also note that the fix is for stock nougat. I have already seen in the cedric devices that the upcoming Oreo may apply the same type of fix on boot (i.e. changing ownership of key folders and files).
Happy to answer any questions if people ask. Please keep questions for this device in this thread.

Is there any hope to fix IMEI 0?

It all depends on what you have or haven't done. If you flashed another persist, you're out of luck. If you haven't flashed another persist, back it up now and save it to the cloud so you never lose it. Then the principles in the guide may help. You can see if you are affected or not by following the section 1), as long as you are on a stock nougat rom.

Dude , thank you so much for that thread and Info. Finally someone is starting to explain the root cause of this IMEI/4G/Volte mess in our devices. Unfortunately I got my phone second hand and the dude had flashed a lineage ROM on it. He had mentioned radio problems but has said he had flashed the wrong modem and fixed it. The phone was 100% operational with the Lineage ROM he had on it so I didn't think much of and I figured since I've been rooting/flashing my phones since the day I got my first android, I could deal with it anyway. In any case, I soon went to flash an 8.1 ROM and discovered my IMEI gone. Eventually I found a few 8.1 ROMs that worked and I'm completely happy with AEX 5.2 which I'm on now. I have the EFS and Persist backups as of the moment I acquired the phone. I wondering though if there is a way to tell if my persist is the one that is supposed to be there or if the owner flashed a different persist? Also when I input the terminal command from your post it returns a list of folder within persist but no ownership tags as shown in your post.

I think the only way to tell if the persist is definitely the one for the phone is to revert to stock nougat, follow the guide (I did find that one of the posters in the thread tried it on their sanders device and it worked for them - fortunately there is enough consistency so that the guide applies to many phones) to fix the folder ownership, then erase EFS and reboot. If your IMEI comes back, you're in luck. If it doesn't, hold onto your EFS backup for the rest of your phone's life!
(Also note that reverting to stock nougat should be done carefully. Don't downgrade the bootloader, otherwise you'll run into other problems..)
Also, just to emphasize, the output from the commands that list ownership is taken from nougat. Oreo has changed things, so it's not surprising if you get different things. E.g. Cedric's Oreo appears to not have an rfs user, instead it is using something like oem_2903.

Just wanted to chime in and say that this has fixed my phone! I've had iffy VoLTE and other issues since going back to stock and couldn't even use custom ROMs since it wouldn't allow me to search for a network. This seems to have cleared it all up. Thanks!

thanks a lot. I've had no lte data since the day I got the phone, but thanks to this it is fixed.
edit: for verizon peoples who only had 3g, I can confirm that lte still works after flashing at least msm xtended so probably other roms too.

Folks, the rom above was a test version of the Oreo soak test that I made. Unfortunately it seems the is an issue on the build. I have pulled it for now. Hoping that a downgrade to stock nougat will help fix it. Goodness knows I'm trying to help with the IMEI issue, not contribute to it *facepalm*
Edit: user got everything back by flashing a nougat twrp flashable build. So issue was definitely just in that particular Oreo build

Back up the EFS, run these commands, then run the fastboot commands to wipe your modem. It will rebuild and you should have imei back

Can you check if you have a file dhob.bin.bak after running the find command in the post? Many people who don't have success with the guide are missing that file.

I have successfully executed this procedure and I got a hd calling option or an hd calling icon..is that correct??. Then I backed up the efs and again i got to custom ROM then and flashed the efs partition but no sign of volte or can't make call from Jio...
The question is can I use the efs partition which I recovered through this on a custom ROM?

Answer as per the other thread:
Yes, I get an H+ icon on my phone, so that would be what you'd want if the procedure worked. If Volte doesn't work on the custom rom, then it's a custom rom issue.

my volte worked without restoring the efs... just fixed permissions from stock, flashed rom, everything worked.

Bro how you can fix the volte can you tell me?

just flashed stock and fixed the permissions like op said. when i rebooted everything was fixed and still works with at least gzosp-based roms and probably others too. no tricks needed.

Thank you bro...it's worked backuped the efs and persist partion on the stock ROM and again flashed pe ROM and reflashed the efs and persist volte is now working fine thanks....

is there a way to get this post pinnedor something?

Hi guys. Reported success earlier in the thread but my issues came back. IMEI is there, everything functions properly in stock, but in non-stock I get an "error searching for network" that I didn't get before I flashed a broken gapps file that edited my persist file.
I know my persist partition is currently stock, and I'd like a copy of a working persist file from an xt1806 that I can copy my known good persist data to. Thanks!

Linux user unable to find the correct process to get a custom rom installed and very confused

Hey guys ive been perusing the web for days, i cant seem to find the method that should be used to get a new rom on my phone i have the SM-N950U1.
i am also a linux user and not sure exactly how i should go about flashing when i dont have a windows machine. does any one have a clear start to finish idea how to correctly do this and what i will need to complete the root, flash. im sorry if it covered some where i hae looked but evidently not found a method. any assistance would be very grateful i really dont like proprietry bloatware and i know this is an older phone. thank you all for any assistance!

1. Unlock bootloader.
This will factory reset your phone.
I forgot the exact process of this, was a long time ago when I did this.
2. Flash a Custom Recovery with "ODIN"
"TWRP" is the most common Custom Recovery.
I think ODIN is Windows-only Software, but you could use a VM.
3. Boot into Custom Recovery & flash the Custom_ROM.zip file.
You can try out Custom ROMs from XDA from the ROMs-Section.
I may have forgotten something, so take this with caution

First of all the SM-N950U1 (snapdragons soc models) has a permanent LOCKED bootloader so no TWRP recovery.
The post from dreamytom is for SM-N950F/F-DS/N exynos models.
You can only root the SM-N950U1 models, with nougat firmware with root only, depending on the bootloader you are on and if you can find the files needed for it. The thread for that "Extreme Syndicate root thread " has been disconnected and the files taken down, so might want to ask in that thread for someone to share the files for you.
Best of luck!
