Hello,

I received my Lenovo Y700 tablet ordered on aliexpres with the bootloader open and a bad rom 15.0.549.

I used RSA to upgrade to globalrom 15.0.358 recently.

I relocked the bootloader for Netflix and others,

I wanted to know if you think it is necessary to change the boot since it was changed by a seller? (security of my data on the tablet).

Does the fact of storing ROMs by yourself guarantee the security of my data?

sorry for the newbie questions and my poor english.

Thanks for your job and tutorials.
[Lenovo Legion Y700] project_2501:
Were you able to update through the system app instead of recovery? You can payload dump the ota update and flash it either with fastboot or QFIL. More than likely your device is region locked to ROW and you will need to use a modified vendor_boot.
[Lenovo Legion Y700] xeropressence:
Never bothered to unlock the bootloader after converting from CN to global via RSA

Was able to update through the system app without issue.

Edit:

I'll note that I've installed global OTA's before via the app as well, i was just being inpatient with this one.
[Lenovo Legion Y700] Breed43214:
Early days, but the battery life seems MUCH improved.
[Lenovo Legion Y700] deeks888:
agreed standby power use seems better. would lose battery when screen off very quickly on 240

Anyone did trying to make a dual ROM for latest global 15.0.358 with these tools?

Post in thread 'ZUI 16 Android 14 for y700 2023 cn released' https://xdaforums.com/t/zui-16-android-14-for-y700-2023-cn-released.4680273/post-89610752

I think, there is a metod to update modified 15.0.240 (with cracked vendor_boot for run over PRC region) via fastboot flashing mode, when we get a dual ROM that version.
[Lenovo Legion Y700] Breed43214:
Is there any point when it's available on RSA?
[Lenovo Legion Y700] hitin911:
Is already available two days ago.

But, in RSA it is for QFIL EDL mode flashing, terajima -alc early and rydeen8 can make a dual mode ROM for fastboot flashing. Tools link i am add above.

There is a separate thread for that tools.

Thread 'Need tools and tutorials about dump from device and make ROM images' https://xdaforums.com/t/need-tools-and-tutorials-about-dump-from-device-and-make-rom-images.4680973/
[Lenovo Legion Y700] Breed43214:
I know. So why would you make a ROM with the above tools when it can be downloaded via RSA?
[Lenovo Legion Y700] hitin911:
Need fastboot mode rom to update 15.0.240 with modified vendor boot, and save all user data. Not RSA when it format all and loosing all data at all.

And there's a second metod to flash global rom over the cn version such as 15.0.737 via fastbootD, when you haven't a PC at all, therefore use a another smartphone and run fastboot commands to flash from it.
[Lenovo Legion Y700] batkrak:
What's the difference between a "dual-mode ROM" and a "NON-dual-mode ROM"?

I've seen links posted to these 2 types of ROMs and thought it's just uploaders creating weird .zip file names.

Example:

TB320FC_ROW_OPEN_USER_Q00031.0_T_ZUI_15.0.240_ST_240411.zip - NON-dual-mode?

TB320FC_ROW_v15.0.240_dual.zip - dual-mode?

What's the difference? One is "stock" and the other is somehow modified?
[Lenovo Legion Y700] ViXoZuDo:
Hi, right now I'm with the 240 (vendor_boot modified + magisk). I have seen that there is the 358 update available. I wanna know a couple of things:

1. If I OTA update it, will my tablet lock again? (not sure if the OTA would rewrite the vendor_boot). I don't want to reinstall everything again.

2. What's the current state of CN room (795)? does it still need to patch google services manually? Does the languages are fully working (not even 1 Chinese character)? If it's working perfectly, maybe I just update to the CN room.

3. Whats the current state of locking/unlocking the different rooms?

4. Any update about permanently changing the region of the tablet?
[Lenovo Legion Y700] Breed43214:
1) Yes. Google backup should speed this up though.

2) There is a newer CN ROM 16.0.388 which updates the OS to ZUI 16 (Android 14) which apparently has much better English (and now other languages) support. Not sure how perfect it is though as I've not used it myself as I'm on Global. Still needs Play Services installed manually. CN ROMs always will, as it's banned in China.

3) Don't understand this question.

4) No.

There's also a new NEC firmware out, which means those who last had .795 on their tablets can now flash and lock their bootloaders if they so wish.
[Lenovo Legion Y700] hitin911:
Dual mode ROM is unofficial dump image, but allow fastbootD mode for flashing also as ordinary EDL mode too.

Non dual is simply for EDL QFIL/RSA only flashing. Some of it maybe full original from Lenovo servers.
[Lenovo Legion Y700] hitin911:
15.0.761 and 15.0.795 are not allow to unlock / lock bootloader. So, it is need to downgrade or update to do it before.

If you wish to flash a japan NEC 15.0.051 over china 15.0.795 there is no need to unlock now. Also, if you choose to update to zui 16 china based on Android 14.
[Lenovo Legion Y700] S4NS3:
I confirm that it has been updated to global version 15.0.358 (139MB) from v240. A note, for the OTA update had to unroot the tablet, because it does not allow update if it is rooted.
[Lenovo Legion Y700] pwoyorkie:
It's been years since I messed with ROMs.

I've just ordered from Aliexpress and it ships with the global ROM. Netflix HD not supported, no OTA etc.

Can I ask, can I just connect to RSA and flash the official global ROM and not have any issues? There's so much info about I'm getting confused. Are there any other steps I need to do?
[Lenovo Legion Y700] roldev:
AliExpress sellers usually ship with 'fake' global rom, outdated Chinese one with added languages, Google services, etc. Usually ships with unlocked bootloader.

So it's easy to connect to RSA, the S/N and warranty status will not be recognized officially.

Look for the Legion Y700 2023 on the device list and will appear the current, Global ROM. There is a warning that is not supported officially for the device since it's CN, but go forward step by step and will be done under 10 minutes.

The Netflix HD is not supported because of unlocked bootloader. You can relock or root and install a magisk module to fix this. There is a thread in this sub-forum about it.

OTA will be available too, if you relock the bootloader. I think that otherwise OTA can be sideloaded, but didn't try it since no OTA for the official global ROM till now.

Hope this helps.
[Lenovo Legion Y700] pwoyorkie:
Thank you for the reply. You've cleared up all my questions and even ones I didn't ask! Appreciate you taking through time :)

Can I lock the bootloader through RSA or do I use adb?
[Lenovo Legion Y700] roldev:
Relock should be done from fastboot. There are other thread here about the exactly command for the device. Didn't remember it right now. Should be ' fastboot flash lock' or go-lock. Not sure, sorry.
[Lenovo Legion Y700] pwoyorkie:
Thank you! Gives me a clue on where to search.

Since then I have started a separate thread for this topic.

PC Mode resolution

Has anyone gotten a better resolution out of "PC Mode"? I have a y700 2023 (512GB model with global firmware) and I connect by the bottom (long side) USB-C, but the resolution on a 4K monitor seems less than 1080p. I assume this is an Android 13...

[Lenovo Legion Y700] DustoMan:
So my tablet with the Chinese ROM should be arriving Thursday. I just wanted to confirm that this new Global ROM does support pen input properly when the Japanese NEC ROM didn't. Cause it reads in the translated links like it should. Also I should be able to unlock install the Global ROM and relock without issue right? Since surly whatever version this Chinese ROM is, it should have a lower index number. Just looking for confirmation. Thanks!

Edit: wait so only if it's a specific Chinese version that I need to unlock. If it's not that one version, I can flash without unlocking?
[Lenovo Legion Y700] -Zeta-:
bought one a few days ago using 15.0.677, no need to unlock bootloader, just using the RSA to flash to Global 15.0.139
[Lenovo Legion Y700] anGel_pLayer:
Tablet from Ali came in today with CN rom. Updated it to 737 then just flash the global rom with RSA. No need to unlock as well. Still got Widevine L1.
[Lenovo Legion Y700] adek89:
If I bought Lenovo Legion Y700 2022 from Aliexpress, can I use the rescue_and_smart_assistant_v6.8.4.13_setup program to upload the global? Can you send me the one that was bought from Aliexpress? I have it rotated and bootloader unlocked
[Lenovo Legion Y700] giangnvh:
I can second that Y700 2023 CN xxx.737 could restore directly to Global xxx.139, without unlock bootloader.
[Lenovo Legion Y700] Brutal-Force:
I just stopped in to say I was able to RSA (Rescue and Smart Assistant) my Lenovo Legion Y700 2023 from China version into the English Version TB320FC. No one was really clear on the steps.

1. Download the RSA and follow instructions for selecting the Legion Tab ROW.

2. Find your SN in the Lenovo Vantage App on your device.

3. Follow instructions to boot into recovery.

Turn off the device.

Hold the up arrow on your device and plug in the USB. (Continue to hold down until the RSA finds your device, don't let go before it does)

Follow instructions and flash. Wait until finish then reboot.

4. Enjoy your new version of the Lenovo Legion Tab.

Edit: This was for the 16GB/512GB edition.
[Lenovo Legion Y700] Clalala:
Hmmm. been trying to get mine to work today (on the .737 CN version), and it just says "FAIL", via the RSA. Will keep trying!

Edit:

Tried a different cable and seems to be making progress this time!

2nd edit:

Different cable was successful! Did not have to unlock bootloader either, straight upgrade via the RSA. The RSA does give a warning stating this method is risky though.
[Lenovo Legion Y700] Dimon1358:
Hi, can someone confirm if Lenovo Pen AP500U works on a global ROM?
[Lenovo Legion Y700] Brutal-Force:
I have this one which works with the global ROM.
[Lenovo Legion Y700] Dimon1358:
Thanks for the reply, I'm going to install global ROM on a x.737 Chinese ROM.

Ps. can someone check the battery capacity when the tablet is fully charged (Aida64/aBattery app), mine shows 4250mAh when 100% charged instead of 6550mAh.
[Lenovo Legion Y700] DustoMan:
Oh good. I just ordered that one. I got the Precision Pen 2 and it did not work, but that may not had been the tablets fault. The pen was dead after charging. I couldn't get the thing to turn on. No matter what buttons and how long I pushed them.

I just wanted to update you guys. I got my tablet today. Went from Chinese ROM to Global without unlocking like you all said. I can't stress enough how much USB ports make a difference. I could not get it to flash with my desktop PC with fancy fast USB 3.1 Gen 2 ports all around it. Tried multiple cables. No dice. I had to borrow my wife's Dell XPS 13 laptop to get it done using a USB Type A probably 2.0 speed port. I did have to manually install the Qualcomm USB driver though because for whatever reason what was downloaded with the Rescue program didn't work. In the end, now I have the Global ROM and I'm super happy with this thing. It is freaking sick! Finally a tablet with a smaller screen size I can be happy with and it's not iOS! Thank you all for your assistance.
[Lenovo Legion Y700] Brutal-Force:
I took at look at Aida 64. The Battery Capacity at 100% (Reported by Android) is at 6550mAh. You aren't looking at the Charger counter are you? If you are looking at the Capacity and it is only 6550mAh, that is weird.
[Lenovo Legion Y700] Dimon1358:
I was looking at charge counter, because I thought that it showed current capacity and "reported by android" showed capacity of a new battery for a reference.
[Lenovo Legion Y700] ekafithra:
Hi, with this global rom, does game assistant working?
[Lenovo Legion Y700] Tenun:
Work but many features removed such as hang up is not present
[Lenovo Legion Y700] Nightf0x_007:
Hello guys, sold my ipad pro 2018 and looking to replace it with lenovo y700 2023 or samsung tab s9, whats your thoughts guys on tab s9 vs lenovo ?, lenovo cheaper than 2nd hand s9, screen size better for me, more ram 12gb vs 8gb in the samsung (concerning me), is there a big difference btw. Both in terms of emulation (psp psvita ps2 gamecube wii & especially switch) and i ofcourse will root the device + anybody knows when aliexpress prices drop as it went up since a couple of days or if there is a another cheaper place to get from
[Lenovo Legion Y700] roldev:
Legion Y700 2023 is my choice for tablet. Compact and powerful. I won't use it for gaming, but for work. It has good price in AliExpress. Just need to change the ROM and adapt your needs.
[Lenovo Legion Y700] roldev:
Please check my answer above.
[Lenovo Legion Y700] Brutal-Force:
- Lenovo has available 16GB/512GB

- AliExpress if you want the best price. Mine took about 21 days in shipping from Lenovo on AliE.

- Lenovo is over half the price of the S9 if cost plays into it.

- I'd say S9 if money isn't an issue, you are dead set on a larger screen, you want OLED, and you have to have the newest processor on a tablet. Otherwise Y700 2023 beats it handily.
[Lenovo Legion Y700] gonzothewicked:
Not sure which global rom install method you're using, but the method I used described at the begging of this thread using Lenovo's recovery assistant, the game assistant works beautifully.
[Lenovo Legion Y700] ekafithra:
Yes, the one from RSA. Thanks.

Edit: I'm happy to report the RSA firmware works really well, only need to enable usb debugging, no bootloader unlock. Lenovo pen is working, game assistant is there (although not as many feature as the chinese one). 5G wifi is working. Thanks all.
[Lenovo Legion Y700] Janaboy82:
This new global RSA firmware is containing all languages? Including Hungarian?

Thanks :)
[Lenovo Legion Y700] ekafithra:
I see Magyar, but can't find "Hungarian". Is it what you looking for?
[Lenovo Legion Y700] Janaboy82:
Yes, thank you :)
[Lenovo Legion Y700] Konkorouu:
is this only work on 15/512?
[Lenovo Legion Y700] Brutal-Force:
I am pretty sure it works with both the 12GB and 16GB devices.
[Lenovo Legion Y700] Konkorouu:
But i tried

I tried on 12gb from 737
[Lenovo Legion Y700] Konkorouu:
But i tried

I tried on 12gb from 737. There is red message shown, your current system is not cimplitable
[Lenovo Legion Y700] Brutal-Force:
The Y700 2023 model?
[Lenovo Legion Y700] -Zeta-:
Try some older devices with USB 2.0 ports
[Lenovo Legion Y700] project_2501:
Did you copy and replace the persist partition with partition manager within QFIL first (after flashing through RSA, and before first boot)? It may still be a requirement for region changing like previous generation Lenovo devices.
[Lenovo Legion Y700] Konkorouu:
Yes y700 2023
[Lenovo Legion Y700] Konkorouu:
No. I didnt replace any item. I just start flashing with RSA. I just follow the instructions
[Lenovo Legion Y700] Breed43214:
Well, it took 5 weeks and some change, but mine finally arrived today.

It came with 15.0.677 CN firmware. I used the Lenovo RSA tool to flash the 15.0.139 RoW ROM on it without issue. No need to unlock bootloader.

What a £150 saving! Thanks to all on here.
[Lenovo Legion Y700] goolby:
I paid 241.87$ and 45.96$ import tax for the 12Gig model and it came with the Chinese "Global ROM" V15.0.549 (bootloader unlocked chinese modified rom to include more languages) so I was able to update with the RSA tool to Official Global Rom V15.0.139 and lock the bootloader.

Verry happy with the savings, retail here it's 550$ 😳
[Lenovo Legion Y700] Onimusha117:
Guys... I tried to flash the device using RSA. And now my device is locked

It has a new update 774 before flashing. I installed the update.... And followed RSA flashing and now my device is locked.... Any help
[Lenovo Legion Y700] Onimusha117:
Hmmm.... My tab just updated by itself.... I did not read the info and after flashing, now my tab is a brick. I might have to wait for the next global rom....
[Lenovo Legion Y700] goolby:
There seems to be some problems with 774, maybe they put something in this latest CN rom so it will not cross flash successfully to the global rom...

According to this link (use Chrome to translate to english) the system might get corrupted...

Also found some more info about 774 failure in this link. Hope you can restore it :).
[Lenovo Legion Y700] Breed43214:
Potentially, yes. If you had 761 or 774 on the tablet, this is the one instance where you would have needed to unlock the bootloader before you flashed the RoW ROM, as you're then flashing an older ROM.

Have you tried unlocking the bootloader? https://gigglehd.com/gg/review/15165218

You'll need to wait for the next Global ROM, I think if you can't get it unlocked.
[Lenovo Legion Y700] Onimusha117:
Yeah, I tried all command from ADB and nothing worked. Double check the unlock status and it is not allowed. Haha.... Guess I have to wait then.

Also, is Lenovo great with...new updates for global android tab/phone in a general? I hope it is cuz this is new...
[Lenovo Legion Y700] project_2501:
Before the region change, your device was unlocked running the CN build, correct? I wonder if the rollback index changes between CN and Global? My only concern is you might not be able to region change back to the CN build with a locked bootloader without complications like others are now experiencing.
[Lenovo Legion Y700] goolby:
"Before the region change, your device was unlocked running the CN build, correct?"

Yes, bootloader was unlocked.

From what I could get online, the rollback index changes only when when you unlock the bootloader (not when you lock it), with the number from that firmware so in theory because my bootloader is locked now on V15.0.139, I could unlock it and flash to a firmware with the rollback index higher than 1701388800

Either way, my goal was to be able to flash to the RoW rom and have the bootloader locked and Widevine L1 Certification so I'm not planning to ever go back to the chinese rom.

PS: Even if the RoW rom gets lesser updates, V15.0.139 is Android 13 and after using the tablet for a couple of weeks I didn't found any bugs or had any problems with it, all is running perfectly.
[Lenovo Legion Y700] goolby:
Maybe Japan (NEC) will release a newer one sooner than RoW because Lenovo isn't that great with global firmware releases... :rolleyes:
[Lenovo Legion Y700] sean.trinidade:
Based on their website, Lenovo is expecting to release A14 by the end of July, so I don't really think we'll get many more feature updates before then
[Lenovo Legion Y700] project_2501:
Can anyone extract the ZUI Global apps ( File Manager, Legion Assistant, Lab features, etc. ) to test on CN build?
[Lenovo Legion Y700] Onimusha117:
Terajima closed his site? I could not find the site anymore. He offered such great info....
[Lenovo Legion Y700] goolby:
Yes, I asked him in DM and he said that he quit. His info and his choice so I respect it.
[Lenovo Legion Y700] daidey:
I have just found the latest global rom 240 is released!

I had flashed nec rom 022, and rsa the global rom 139 with bootloader unlocked. Today, I upgraded the global rom to 240 via system update in setting, then I can lock the bootloader again. Now, I can use Netflix without any problem. 👍
[Lenovo Legion Y700] roldev:
Just a quick question.

When you lock / unlock the bootloader wipe the data? That's the reason I avoid to lock it... Thanks.
[Lenovo Legion Y700] asim0:
I also received the ota update from 139 to 240 while the boatloaer was unlocked.
[Lenovo Legion Y700] daidey:
Unfortunately, whenever you unlock or lock the tablet, it wipes all data. 😓

If anyone wants it, please give it to them.
[Lenovo Legion Y700] bitz_dv:
OK guys I am stuck. I can not get my tablet to update to the global rom using RSA tool or QFIL. QFIL log attached below. Bootloader is unlocked, I did update from 15.0.654 to 15.0.723 using the fastboot rom found here (I updated thinking that maybe 654 was too low a version to update but that turned out not to be the case). Previously my device would not take OTA updates after unlocking bootloader, rooting and removing root (could something be lingering from this?) I followed gigglehd guide to updating to Global Rom.

The log file mentions not being able to find meta_cli.exe several times, and the log ends with a few errors. I am not sure where I am going wrong. Drivers, QFIL/QPST version platform tools etc all look correct.
[Lenovo Legion Y700] Breed43214:
What version are you trying to flash? .139 or .240? From the log it looks like .139? Are you using QFIL to try and install the ROM package that RSA downloaded?

Why not try using .240 from below using the fastboot method? You should be able to if your bootloaders unlocked. Just go into fastboot and run flash_all.bat as per the article you linked.

test - Google Drive

drive.google.com
[Lenovo Legion Y700] bitz_dv:
.139 that was downloaded through RSA.
[Lenovo Legion Y700] bitz_dv:
Actually I see that the drive posted by @terajima-alc has a .240_dual image with a .bat file. Would that also work for flashing it?
[Lenovo Legion Y700] Breed43214:
Yeah, noticed from the log. Updated my post above. Give it a go.
[Lenovo Legion Y700] bitz_dv:
.240 is safe to lock bootloader after correct?
[Lenovo Legion Y700] Breed43214:
It has the latest rollback value, so it should be.
[Lenovo Legion Y700] bitz_dv:
Yep, it's safe, I just relocked using fastboot flashing lock and it still boots!

Curious if future OTAs will work since I was previously having issues, but for now I am happy, have the global rom and working on setting everything back up.
[Lenovo Legion Y700] dieandromeda:
How to flash from china 774 to global 240?. Latest RSA that available is firmware 139. I guess we need to flash using QFiL?.
[Lenovo Legion Y700] ViXoZuDo:
Global 240 is available thought RSA now... Was able to install it on top of 774, but have the "The current system is not compatible with the hardware" message.
[Lenovo Legion Y700] googdot:
Going to grab one off of Ali this week...is it still best to get the sealed CN ROM version?
[Lenovo Legion Y700] Breed43214:
Did you unlock the bootloader? If not, I'd go back to .774, try unlocking, then reflash .240 using fastboot flashing rather than RSA.
[Lenovo Legion Y700] goolby:
It all depends on what firmware version it has (sealed CN rom)... latest CN firmware .761, .774 might have some issues flashing to RoW rom, check for ex. @ViXoZuDo post above.

I for example bought one that had "Global ROM" V15.0.549 (bootloader unlocked chinese modified rom to include more languages) so I was able to update with the RSA tool to Official Global Rom V15.0.139 and lock the bootloader.

Take your time and read a bit the top threads here to get an idea on how this works.

PS: there is no right answer because there are so many outcomes from people that flashed with or without bootloader unlocked, with RSA or without it but I think that for now there is a high probability of success even if you end up soft bricking your device... again, take your time to read thru the threads.
[Lenovo Legion Y700] Breed43214:
Agree with @goolby here. Something in .761 and .774 has definitely made flashing ROW ROM a bit harder. Probably deliberate by Lenovo.

As long as you get one with <.761 (which is highly likely) then you should in theory have no issues. Though no-one as of yet has went from <.761 straight to .240 from what I can tell, as it's only just been released. Success up to now has been <.761 to .139 without unlocking bootloader via RSA, but RSA has replaced .139 with .240 now.

I would definitely unlock the bootloader if I were doing it now. @bitz_dv has confirmed above it's still re-lockable on .240, so there's no harm in doing it and it makes recovery (if needed) much easier.
[Lenovo Legion Y700] dieandromeda:
Any update?
[Lenovo Legion Y700] Janaboy82:
I am on latest nec rom, locked bootloader, can i upgrade back to the global lenovo rom?

If yes, how?
[Lenovo Legion Y700] jianglai:
Anyone getting 240 from 139 via OTA? I have my bootloader locked but it still says 139 is the latest.
